(1) The number of shares of common stock, par value $0.01 per share, of Dime
    Bancorp, Inc., a Delaware corporation ("Dime common stock"), to be
    registered pursuant to this registration statement is based upon the number
    of shares of common stock, no par value, of Hudson United Bancorp, a New
    Jersey corporation ("Hudson common stock"), presently outstanding or
    reserved for issuance under various plans or otherwise expected to be issued
    or to become issuable upon the consummation of the proposed merger
    transaction to which this registration statement relates, multiplied by the
    exchange ratio of one share of Dime common stock per share of Hudson common
    stock.
(2) Each share of Dime common stock is accompanied by a preferred stock purchase
    right that trades with the Dime common stock. The value attributable to such
    rights, if any, is reflected in the market price of Dime common stock. Prior
    to the occurrence of certain events, none of which have occurred as of this
    date, the rights will not be exercisable or evidenced separately from the
    common stock.
(3) Pursuant to Rules 457(f) and 457(c) under the Securities Act of 1933, as
    amended, the registration fee is based on the average of the high and low
    sales prices of Hudson common stock, as reported on the New York Stock
    Exchange on February 4, 2000 ($23.09), and computed based on the estimated
    maximum number of such shares that may be exchanged for the Dime common
    stock being registered.
(4) Pursuant to Rule 457(b) under the Securities Act of 1933, as amended, the
    amount of the registration fee has been reduced by $317,293.94, the amount
    paid to the Securities and Exchange Commission on November 19, 1999 with
    respect to this transaction. The difference of $14,109.73 is paid herewith.
                            ------------------------

    THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR
DATES AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL
FILE A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION
STATEMENT SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(a) OF
THE SECURITIES ACT OF 1933 OR UNTIL THE REGISTRATION STATEMENT SHALL BECOME
EFFECTIVE ON SUCH DATE AS THE COMMISSION, ACTING PURSUANT TO SAID SECTION 8(a),
MAY DETERMINE.

                               ------------------
    Dime and Hudson have entered into a merger agreement. Dime will be the
surviving corporation in the merger and will change its name to DIME UNITED
BANCORP, INC. In this document we refer to the combined company as Dime United.
Immediately after the merger, Dime stockholders will own 56% of the outstanding
Dime United stock and Hudson stockholders will own 44% of the outstanding Dime
United stock. The merger will be TAX-FREE TO BOTH DIME AND HUDSON STOCKHOLDERS
except for taxes on cash received by Dime stockholders for fractional Dime
United shares.

                               DIME STOCKHOLDERS

    This document is being sent to you for use at the special meeting of
stockholders of Dime to be held at Chelsea Piers, Pier 60, 23rd and Hudson
River, New York, New York 10011 at 10:00 a.m. on March 15, 2000. At this
meeting, Dime's board of directors will ask you to adopt the Agreement and Plan
of Merger between Dime and Hudson.

    YOU WILL RECEIVE 0.60255 OF A SHARE OF DIME UNITED STOCK FOR EACH SHARE OF
DIME STOCK THAT YOU OWN. Based on the $22 1/4 closing price of Hudson stock on
February 7, 2000, THE IMPLIED VALUE OF ONE SHARE OF DIME STOCK WAS $13.41. This
value will fluctuate prior to completion of the merger and you will not know the
value of what you will receive in the merger when you vote.

    Dime's board of directors has approved the merger. The board believes that
the merger is in the best interests of Dime stockholders and strongly encourages
you to vote "FOR" adoption of the merger agreement. In approving the merger, the
board considered many factors, including the opinion of its financial advisor,
Credit Suisse First Boston. This opinion states that the exchange ratio of
0.60255 of a share of Dime United stock for each share of Dime stock is fair,
from a financial point of view, to Dime stockholders.

                              HUDSON STOCKHOLDERS

    This document is being sent to you for use at the special meeting of
stockholders of Hudson to be held at The Sheraton Crossroads, Crossroads
Corporate Center, Route 17 North, Mahwah, New Jersey 07495 at 9:00 a.m. on March
15, 2000. At this meeting, Hudson's board of directors will ask you to approve
the Agreement and Plan of Merger between Dime and Hudson.
    YOU WILL RECEIVE ONE SHARE OF DIME UNITED STOCK FOR EACH SHARE OF HUDSON
STOCK THAT YOU OWN. THE IMPLIED VALUE OF ONE SHARE OF DIME UNITED STOCK ON
FEBRUARY 7, 2000 WAS $22 1/4, which was the closing price of Hudson stock on
that date. This value will fluctuate prior to completion of the merger and you
will not know the value of what you will receive in the merger when you vote.

    Hudson's board of directors has approved the merger. The board believes that
the merger is in the best interests of Hudson stockholders and strongly
encourages you to vote "FOR" approval of the merger agreement. In approving the
merger, the board considered many factors, including the opinion of its
financial advisor, Goldman, Sachs & Co. This opinion states that the exchange
ratio of one share of Dime United stock for each share of Hudson stock is fair,
from a financial point of view, to Hudson stockholders.

                          YOUR VOTE IS VERY IMPORTANT

     QUESTIONS AND ANSWERS ABOUT VOTING PROCEDURES FOR THE SPECIAL MEETINGS

Q:  WHAT DO I NEED TO DO NOW?

A:  After you have carefully read this document, indicate on your proxy card how
    you want your shares to be voted. Then sign and mail your proxy card in the
    enclosed prepaid return envelope as soon as possible. This will enable your
    shares to be represented and voted at the Dime special meeting or the Hudson
    special meeting.

Q:  WHY IS MY VOTE IMPORTANT?

A:  If you do not return your proxy card or vote in person at the appropriate
    special meeting, it will be more difficult for Dime and Hudson to obtain the
    necessary quorum to hold their special meetings. In addition, if a Dime
    stockholder fails to vote, by proxy or in person, that will have the same
    effect as a vote against the merger agreement. The merger must be approved
    by a majority of the outstanding shares of Dime stock entitled to vote. It
    must also be approved by a majority of the shares of Hudson stock that are
    voted at the Hudson special meeting.

Q:  IF MY SHARES ARE HELD IN STREET NAME BY MY BROKER, WILL MY BROKER
    AUTOMATICALLY VOTE MY SHARES FOR ME?

A:  No. Your broker will not be able to vote your shares without instructions
    from you. You should instruct your broker to vote your shares, following the
    directions your broker provides.

Q:  WHAT IF I FAIL TO INSTRUCT MY BROKER?

A:  If you fail to instruct your broker to vote your shares and the broker
    submits an unvoted proxy, that broker non-vote will be counted toward a
    quorum at the special meeting. This will not count as a vote for or against
    the merger agreement at the Hudson special meeting, but it will have the
    same effect as a vote against the merger agreement at the Dime special
    meeting.

Q:  CAN I ATTEND THE MEETING AND VOTE MY SHARES IN PERSON?

A:  Yes. All stockholders are invited to attend their special meeting.
    Stockholders of record can vote in person at the special meeting. If a
    broker holds your shares in street name, then you are not the stockholder of
    record and you must ask your broker how you can vote at the special meeting.

Q:  CAN I CHANGE MY VOTE?

A:  Yes. If you have not voted through your broker, there are three ways you can
    change your vote after you have sent in your proxy card.

     -  First, you may send a written notice to the person to whom you submitted
        your proxy stating that you would like to revoke your proxy.

     -  Second, you may complete and submit a new proxy card. Any earlier
        proxies will be revoked automatically.

     -  Third, you may attend the meeting and vote in person. Any earlier proxy
        will be revoked. However, simply attending the meeting without voting
        will not revoke your proxy.

     If you have instructed a broker to vote your shares, you must follow
     directions you receive from your broker to change your vote.

Q:  SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A:  No. You should not send in your stock certificates at this time.

    Dime stockholders will need to exchange their Dime stock certificates for
    new Dime United stock certificates after we complete the merger.
    Instructions for exchanging Dime stock certificates will be sent to you at
    that time.

    Hudson stockholders will not need to exchange their Hudson stock
    certificates after we complete the merger, unless we determine that an
    exchange is legally required. If an exchange is required, we will give you
    instructions on how to do so. Your current Hudson stock certificates will
    represent an equal number of shares of Dime United stock after the merger.

Q:  WHOM SHOULD I CALL WITH QUESTIONS?

A:  Dime stockholders should call the Investor Relations Department of Dime at
    (212) 326-6170.

    Hudson stockholders should call D. Lynn Van Borkulo-Nuzzo, Esq., Executive
    Vice President and Corporate Secretary of Hudson, at (201) 236-2641.

                                    SUMMARY

     This summary highlights selected information from this document. It does
not contain all of the information that is important to you. We urge you to read
carefully the entire document and the other documents to which we refer to fully
understand the merger and the related transactions. See "Where You Can Find More
Information" on page 100. Each item in this summary refers to the page where
that subject is discussed in more detail.

DIME STOCKHOLDERS TO RECEIVE 0.60255 OF A DIME UNITED SHARE PER DIME SHARE;
HUDSON STOCKHOLDERS TO RECEIVE ONE SHARE OF DIME UNITED PER HUDSON SHARE (SEE
PAGE 23-24)

Upon completion of the merger, Dime stockholders will own 56% of the Dime United
stock and Hudson stockholders will own 44% of the Dime United stock.

Dime Stockholders.  When the merger is complete, each Dime stockholder will
receive 0.60255 of a share of Dime United stock for each share of Dime stock
held. We sometimes refer to this 0.60255-for-1 ratio as the Dime exchange ratio.
Generally, no fractional shares of Dime United stock will be issued in the
merger. Instead of fractional shares, Dime stockholders will receive an amount
in cash based on the average market value of Hudson stock over the ten trading
days prior to the date the merger is completed.

For example, if you hold 100 shares of Dime stock, you will receive 60 shares of
Dime United stock and a cash payment instead of the 0.255 of a share of Dime
United stock you otherwise would have received.

Hudson Stockholders.  When the merger is complete, each Hudson stockholder will
receive one share of Dime United stock for each share of Hudson stock held. We
sometimes refer to this 1-for-1 ratio as the Hudson exchange ratio.

SHARE INFORMATION AND MARKET PRICES (SEE PAGES 24 AND 87-88)

Dime common stock is traded on the NYSE under the symbol "DME." Hudson common
stock is traded on the NYSE under the symbol "HU." The following table sets
forth the closing sale prices of Dime stock and Hudson stock for September 14,
1999, the last trading day before we announced the merger, and for February 7,
2000, the latest practicable date before mailing this document to you. This
table also shows the implied value of one share of Dime stock, which we
calculated by multiplying the Hudson closing price on those dates by 0.60255.

We adjusted retroactively the closing price of Hudson stock on September 14,
1999 to account for the 3% stock dividend paid by Hudson on December 1, 1999.

</TABLE>

THE MARKET PRICES OF BOTH DIME STOCK AND HUDSON STOCK WILL FLUCTUATE PRIOR TO
THE MERGER. THEREFORE, YOU SHOULD OBTAIN CURRENT MARKET QUOTATIONS FOR DIME
STOCK AND HUDSON STOCK.

DIME UNITED'S DIVIDEND POLICY (SEE PAGES 24 AND 88)

We have agreed that, after the merger is completed, Dime United will pay cash
dividends at an annual rate of $1.00 per share of Dime United stock. The Dime
United board of directors may, however, change this policy at any time. During
1999, Hudson paid cash dividends of $1.00 per share, before the impact of its 3%
stock dividend, and Dime paid cash dividends of $0.23 per share.

GENERALLY TAX-FREE FOR STOCKHOLDERS (SEE PAGES 51-53)

The merger has been structured as a tax-free reorganization for federal income
tax purposes. Dime and Hudson have received tax opinions from their counsel
regarding the merger. According to these opinions:

- - Dime stockholders generally will not recognize any gain or loss on the
  combination of shares of Dime stock into shares of Dime United stock, except
  for taxes on cash amounts received instead of fractional shares of Dime United
  stock, and

                                        2
<PAGE>   12

- - Hudson stockholders generally will not recognize any gain or loss on the
  conversion of shares of Hudson stock into shares of Dime United stock.

The tax opinions have been filed as exhibits to the registration statement that
registers the Dime United stock to be issued in the merger. Opinions regarding
the tax-free nature of the merger must be issued on the date the merger is
completed. Although the merger agreement allows us to waive this condition, we
currently do not anticipate doing so. If either of us does waive this condition,
we will inform you of this fact and ask you to vote on the merger taking this
into consideration.

This tax treatment may not apply to certain Dime or Hudson stockholders.
Determining the actual tax consequences of the merger to you may be complex.
They will depend on your specific situation and on factors not within our
control. You should consult your own tax advisor for a full understanding of the
merger's tax consequences to you.

DIME'S BOARD OF DIRECTORS RECOMMENDS STOCKHOLDER APPROVAL (SEE PAGES 27-32)

Dime's board of directors believes that the merger presents a unique opportunity
to combine and expand two complementary sets of banking operations in attractive
and contiguous markets in a four-state region that cover an area from
Philadelphia to Hartford. The board consulted with financial and other advisors,
considered many strategic and financial factors and determined that the merger
was likely to accelerate the strategic plans of Dime.

As a result, Dime's board of directors believes that the merger is fair to Dime
stockholders and in the best interests of Dime and its stockholders and has
approved the merger agreement. Dime's board of directors recommends that Dime
stockholders vote "FOR" adoption of the merger agreement.

HUDSON'S BOARD OF DIRECTORS RECOMMENDS STOCKHOLDER APPROVAL (SEE PAGES 32-34)

Hudson's board of directors believes that the merger presents a unique
opportunity to combine two strong franchises to create a premier banking and
financial services company with a presence in New York City and Long Island and
with a commitment and the resources to significantly enhance stockholder value.
The board consulted with financial and other advisors and considered many
factors in making its determination.

As a result, Hudson's board of directors believes that the merger is fair to
Hudson stockholders and in the best interests of Hudson and its stockholders and
has approved the merger agreement. Hudson's board of directors recommends that
Hudson stockholders vote "FOR" approval of the merger agreement.

DIME'S FINANCIAL ADVISOR SAYS THE DIME EXCHANGE RATIO IS FAIR FROM A FINANCIAL
POINT OF VIEW TO DIME STOCKHOLDERS (SEE PAGES 34-40)

Dime's financial advisor, Credit Suisse First Boston, has given an opinion to
Dime's board of directors that the Dime exchange ratio is fair to Dime
stockholders from a financial point of view. A copy of this opinion is attached
to this document as Appendix D. Dime stockholders should read the opinion
completely to understand the assumptions made, matters considered and
limitations on the review undertaken by Credit Suisse First Boston in providing
its opinion. Dime has agreed to pay $11 million to Credit Suisse First Boston,
of which $7 million is payable upon the completion of the merger.

HUDSON'S FINANCIAL ADVISOR SAYS THE HUDSON EXCHANGE RATIO IS FAIR FROM A
FINANCIAL POINT OF VIEW TO HUDSON STOCKHOLDERS (SEE PAGES 40-47)

Hudson's financial advisor, Goldman, Sachs & Co., has given an opinion to
Hudson's board of directors that the Hudson exchange ratio is fair to Hudson
stockholders from a financial point of view. A copy of this opinion is attached
to this document as Appendix E. Hudson stockholders should read the opinion
completely to understand the assumptions made, matters considered and
limitations of the review undertaken by Goldman Sachs in providing its opinion.
Hudson has agreed to pay $9 million to Goldman Sachs, all of which is payable
upon the completion of the merger.

DIME TO HOLD SPECIAL MEETING (SEE PAGES 18-21)

Dime stockholders will be asked to vote to adopt the merger agreement at the
special meeting of Dime stockholders to be held at 10:00 a.m. on

                                        3
<PAGE>   13

March 15, 2000, at Chelsea Piers, Pier 60, 23rd and Hudson River, New York, New
York 10011.

Record Date.  You can vote at the Dime special meeting if you owned Dime stock
at the close of business on February 4, 2000. At that date, there were
110,899,492 shares of Dime stock entitled to be voted at the special meeting.

Required Vote.  To approve the merger, a majority of the outstanding shares of
Dime stock on the record date must be voted in favor of the merger agreement.
Because approval is based on the affirmative vote of a majority of shares
outstanding, a Dime stockholder's failure to vote, a broker non-vote or an
abstention will have the same effect as a vote against the merger.

HUDSON TO HOLD SPECIAL MEETING (SEE PAGES 21-23)

Hudson stockholders will be asked to vote to approve the merger agreement at the
special meeting of Hudson stockholders to be held at 9:00 a.m. on March 15,
2000, at The Sheraton Crossroads, Crossroads Corporate Center, Route 17 North,
Mahwah, New Jersey 07495.

Record Date.  You can vote at the Hudson special meeting if you owned Hudson
stock at the close of business on February 7, 2000. At that date, there were
51,779,603 shares of Hudson stock entitled to be voted at the special meeting.
Required Vote.  To approve the merger, a majority of the votes cast at the
Hudson special meeting must be voted in favor of the merger agreement.

NO APPRAISAL RIGHTS (SEE PAGES 24-25)

In this merger, neither Dime stockholders nor Hudson stockholders have
dissenters' appraisal rights with respect to their shares under Delaware or New
Jersey law.

FINANCIAL INTERESTS OF OUR MANAGEMENTS AND BOARDS OF DIRECTORS IN THE MERGER
(SEE PAGES 55-63)

At the Dime record date, directors and executive officers of Dime and their
affiliates beneficially owned or had the right to vote 2,812,958 shares of Dime
stock, or 2.54% of Dime stock entitled to be voted at the special meeting. At
that date, directors and executive officers of Hudson and their affiliates,
including Hudson, owned or had the right to vote 2,475,260 shares of Dime stock,
or 2.23% of Dime stock entitled to be voted at the meeting.

At the Hudson record date, directors and executive officers of Hudson and their
affiliates beneficially owned or had the right to vote 3,234,107 shares of
Hudson stock, or 6.25% of Hudson stock entitled to be voted at the special
meeting. At that date, directors and executive officers of Dime and their
affiliates, including Dime, did not own or have the right to vote any shares of
Hudson stock.

Our directors and officers have interests in the merger as individuals in
addition to, or different from, their interests as stockholders, such as
receiving salaries and other benefits.

For example, Dime United and DimeBank will assume employment agreements with
Lawrence J. Toal and Kenneth T. Neilson that have provisions regarding the terms
of their employment after the merger. Mr. Toal is the current Chairman and Chief
Executive Officer of Dime and Dime Savings Bank. Mr. Neilson is the current
Chairman and Chief Executive Officer of Hudson and Hudson United Bank. Under Mr.
Toal's agreement, his salary will be at least $900,000 per year, with a target
bonus of at least half of that amount. Under Mr. Neilson's agreement, his salary
will be at least $750,000 per year, rising to at least $1 million per year when
he becomes Chief Executive Officer, and his target bonus will be at least equal
to his salary. Mr. Toal will be granted options to buy 150,000 shares of Dime
United stock, and Mr. Neilson will be granted options to buy 120,000 shares of
Dime United stock. The Black Scholes value of the grant to Mr. Toal is estimated
at $1,595,344 and of the grant to Mr. Neilson is estimated at $1,276,275. Mr.
Neilson also will be granted the right to buy, at $.01 per share, 100,000 shares
of Dime United restricted stock, which, based on the January 31, 2000 closing
price of Hudson stock, would have a value of $2,336,500. Mr. Toal will be
entitled, upon retirement, to additional payments so that his retirement
benefits from Dime United under Dime United's Supplemental Executive Retirement
Plan and other defined benefit plans will equal at least $1,235,000 per year,
starting at or after age 65, expressed as a single life annuity. Mr. Neilson
also will participate in the Supplemental Executive Retirement Plan, and he will
be entitled to additional payments so that his retirement benefits under the
Supplemental

                                        4
<PAGE>   14

Executive Retirement Plan and other defined benefit plans will equal at least
$741,000 starting at or after age 55, expressed as a single life annuity.

Furthermore:

- - The merger will cause all stock options and stock appreciation rights issued
  by Dime or Hudson before September 15, 1999 to become exercisable, and shares
  of restricted stock issued before September 15, 1999 to vest, because the
  merger constitutes a change in control under both Dime's and Hudson's plans
  governing these options, rights or restricted stock. The Dime options, stock
  appreciation rights and restricted stock that are expected to become
  exercisable or vest in connection with the merger have a value estimated at
  $4.78 million. The Hudson options and restricted stock that are expected to
  become exercisable or vest in connection with the merger have a value
  estimated at $11.7 million.

- - Dime employment and change in control agreements provide for special payments
  if the covered employees are fired or leave their employment in circumstances
  entitling them to the merger-related payments. Those payments could total as
  much as $76.5 million, although we anticipate that actual costs will be less.
  We also may pay supplemental pension benefits valued at as much as $15.2
  million in connection with the merger. An additional $16.5 million in death
  benefits to the beneficiaries of Dime officers may vest in connection with the
  merger.

- - Hudson employment and change in control agreements provide for special
  payments if covered employees are fired or leave their employment in
  circumstances entitling them to merger-related payments. Those payments could
  total as much as $9.8 million, although we anticipate that actual costs will
  be less.

The merger agreement also provides that director and officer insurance policies
will be continued or adopted by Dime United and that officers or directors of
Dime or Hudson may be indemnified by Dime United for events that occurred before
the merger.

Each of the Dime board of directors and the Hudson board of directors was aware
of these interests of their respective management and directors and considered
them in its decision to approve the merger agreement.

THE MERGER AND THE MERGER AGREEMENT
(SEE PAGES 23-68)

The merger agreement is attached as Appendix A to this document. We encourage
you to read it because it is the legal document governing the merger.

Merger Expected to Occur in First Quarter of 2000 (see pages 63-64)

The merger will occur only after all of the conditions to its completion have
been satisfied or waived. Currently, we anticipate that the merger will occur in
the first quarter of 2000.

Conditions That Must Be Satisfied or Waived for the Merger to Occur (see pages
63-64 and 67)

As more fully described in this document and the merger agreement, the
completion of the merger depends on a number of conditions being satisfied or
waived, including receipt of stockholder and regulatory approvals and tax, legal
and accounting opinions.

We cannot be certain when, or if, the conditions to the merger will be satisfied
or waived, or that the merger will be completed.

Termination of the Merger Agreement (see pages 67-68)

We may agree in writing to terminate the merger agreement before completing the
merger, even after the stockholders of each of Dime and Hudson have approved it,
as long as the termination is approved by each of our boards of directors.

Either of us may decide, without the consent of the other, to terminate the
merger agreement before our stockholders vote if the other party fails to
recommend the approval of the merger agreement to its stockholders.

In addition, either of us may decide, without the consent of the other, to
terminate the merger agreement, even after approval of the merger agreement by
our stockholders, if:

- - the merger has not been completed by June 30, 2000;

- - a governmental authority denies its approval of the merger, requests the
  withdrawal of our application to it for approval, or indicates an intention to
  deny our application or impose a condition that would have a material adverse
  effect on Dime United; or

- - the other party breaches its representations or warranties and the breach has
  a material adverse effect, or fails to perform its material obligations under
  the merger agreement, in either case, in a manner that cannot be or is not
  cured within 30 days after written notice is made of the breach or failure.

SUBSIDIARY BANKS TO MERGE (SEE PAGE 23)

Upon the merger of Dime and Hudson, Dime Savings Bank will merge into Hudson
United Bank. Hudson United Bank will be the primary banking subsidiary of Dime
United and will change its name to DimeBank.

                                        6
<PAGE>   16

MANAGEMENT OF DIME UNITED AND DIMEBANK (SEE PAGES 47-50)

The boards of directors of both Dime United and DimeBank will consist of 13
former directors of Dime and 12 former directors of Hudson. The Chairman and
Chief Executive Officer of both Dime United and DimeBank will be Mr. Toal. The
President and Chief Operating Officer of both Dime United and DimeBank will be
Mr. Neilson. On December 31, 2002, Mr. Neilson will succeed Mr. Toal as Chairman
and Chief Executive Officer of both Dime United and DimeBank. This succession
may occur earlier if Mr. Toal ceases to serve in these positions.

MERGER TO BE ACCOUNTED FOR AS POOLING OF INTERESTS (SEE PAGE 53)

The merger is intended to be accounted for under the pooling-of-interests method
of accounting. This means that, for accounting and financial reporting purposes,
we will treat Dime and Hudson as if they had always been combined. As a
condition to completion of the merger, we will each receive an opinion from our
independent public accountants that the merger is a pooling of interests.

AMENDMENTS TO DIME CERTIFICATE OF INCORPORATION AND BY-LAWS; COMPARISON OF DIME
AND HUDSON STOCKHOLDERS RIGHTS; HUDSON STOCKHOLDER RIGHTS TO BE GOVERNED BY NEW
STATE LAW AND NEW GOVERNING DOCUMENTS (SEE PAGES 50, 68, 73-80)

The merger will effect amendments to the certificate of incorporation and
by-laws of Dime. These amendments put into place agreements between us regarding
the management of the combined company.

The rights of Dime stockholders currently are governed by Delaware law, the Dime
certificate of incorporation and the Dime by-laws. The rights of Hudson
stockholders are currently governed by New Jersey law, the Hudson certificate of
incorporation and the Hudson by-laws. After the merger, the rights of Dime
United stockholders will be governed by Delaware law, the Dime United
certificate of incorporation and the Dime United by-laws. The changes to the
Dime certificate of incorporation and by-laws to create the Dime United
certificate of incorporation and by-laws are attached as Annex 1 and Annex 2 to
the merger agreement, contained in Appendix A to this document. Except for the
change in Dime's name, these changes are scheduled to expire on December 31,
2002.

The rights of Dime stockholders will not materially change in the merger.
However, Hudson stockholders will have different rights after the merger based
on the change in governing law and the change in governing documents to those of
Dime United. This document contains detailed descriptions of material
differences in these stockholder rights. As examples, from the perspective of
current Hudson stockholders, under Dime United's governing law and documents,
directors may be removed in more limited circumstances, the percentage vote
required to change by-laws has increased, the percentage vote required to change
certain provisions of the certificate of incorporation has decreased,
stockholder nominations and proposals require more formal procedures and
stockholder written consents require unanimity.

DIME UNITED STOCK TO BE ACCOMPANIED BY STOCKHOLDER PROTECTION RIGHTS (SEE PAGES
72-73)

Each share of Dime United stock issued will have attached to it one right to
purchase, under conditions described in a stockholder protection rights
agreement and this document, a fraction of a share of participating preferred
stock of Dime United. These rights are currently held by Dime stockholders under
Dime's stockholder protection rights agreement, which will remain in place after
the merger. These rights will be new rights for Hudson stockholders. See
"Description of Dime United Capital Stock -- Stockholder Protection Rights Plan"
on pages 72 and 73 for a description of this agreement and how it may have
antitakeover effects.

DIME UNITED'S CERTIFICATE OF INCORPORATION AND BY-LAWS TO CONTAIN PROVISIONS
THAT MAY DISCOURAGE TAKEOVERS (SEE PAGES 81-82)

Dime United's certificate of incorporation and by-laws will inherit from Dime's
existing governing documents provisions that may have antitakeover effects. The
provisions may discourage attempts to acquire control of Dime United without
negotiation with the board of directors. These provisions include:

- - the board's authority to issue additional shares of common and preferred
  stock;

                                        7
<PAGE>   17

- - provisions making it difficult to replace a majority of the board since Dime
  United's stockholders will elect only one-third of the directors each year and
  directors may be removed only for cause;

- - the lack of cumulative voting rights in elections of directors;

- - the board's ability to prevent special meetings of stockholders from being
  called without its approval;

- - the need for unanimous consent of stockholders to act without a meeting; and

- - the need for a super-majority vote to amend the by-laws and to amend
  provisions of the certificate of incorporation regarding amendments to
  by-laws, the board of directors, special meetings of stockholders, written
  consent of stockholders, and stockholder proposals.

REGULATORY APPROVALS WE MUST OBTAIN FOR THE MERGER (SEE PAGES 53-55)

We cannot complete the merger unless the Board of Governors of the Federal
Reserve System approves it. Furthermore, we cannot complete the subsidiary bank
merger unless the Federal Deposit Insurance Corporation and the New Jersey
Department of Banking and Insurance approve it. In addition, the merger and the
bank merger are subject to the approval of or notice to other state and
regulatory authorities. We have made the necessary filings with the Federal
Reserve Board, the FDIC, the New Jersey Department of Banking and other
regulatory authorities.

Although we do not know of any reason why we cannot obtain these regulatory
approvals in a timely manner, we cannot be certain when or if we will obtain
them.

DIME GRANTED STOCK OPTION TO HUDSON (SEE PAGES 68-70)

To induce Hudson to enter into the merger agreement, Dime granted Hudson an
option to purchase up to 19.9% of the outstanding shares of Dime stock at a
price per share of $17 3/4. The option could have the effect of discouraging
other companies from trying to acquire Dime until the merger is completed. Dime
may be required to repurchase the option and any shares purchased under it at a
predetermined price, or Hudson may choose to surrender the option to Dime for a
cash payment of $50 million.

Hudson cannot exercise this option unless the merger is not completed and
specified triggering events occur. These events generally relate to business
combinations or acquisition transactions involving Dime. We do not know of any
event that has occurred as of the date of this document that would allow Hudson
to exercise this option.

The Dime stock option agreement is attached to this document as Appendix B.

HUDSON GRANTED STOCK OPTION TO DIME (SEE PAGES 68-70)

To induce Dime to enter into the merger agreement, Hudson granted Dime an option
to purchase up to 19.9% of the outstanding shares of Hudson stock at a price per
share of $29 1/4. The option could have the effect of discouraging other
companies from trying to acquire Hudson until the merger is completed. Hudson
may be required to repurchase the option and any shares purchased under it at a
predetermined price, or Dime may choose to surrender the option to Hudson for a
cash payment of $50 million.

Dime cannot exercise this option unless the merger is not completed and
specified triggering events occur. These events generally relate to business
combinations or acquisition transactions involving Hudson. We do not know of any
event that has occurred as of the date of this document that would allow Dime to
exercise this option.

The Hudson stock option agreement is attached to this document as Appendix C.

UNAUDITED SELECTED HISTORICAL AND PRO FORMA COMBINED PER SHARE FINANCIAL
INFORMATION

    The following table shows information about our basic and diluted earnings
per common share, cash dividends per common share and book value per common
share after giving effect to the merger. This information is called pro forma
information in this document. In presenting the pro forma information, we have
assumed that we merged on January 1, 1996 because the pro forma information
assumes that the merger is accounted for under the pooling-of-interests method
of accounting in accordance with generally accepted accounting principles,
commonly called GAAP. In addition, Hudson information reflects completion of the
mergers of JeffBanks and Southern Jersey Bancorp into Hudson; Dime information
does not include the completion of the acquisition of 28 branches of KeyBank by
Dime Savings Bank effective as of October 18, 1999; Hudson information does not
include the completion of the acquisition of substantially all of the assets of
Lyon Credit Corporation that occurred on October 22, 1999 or the acquisition of
loans and other financial assets, and the assumption of deposits, of Advest Bank
and Trust that occurred on December 1, 1999.

    We expect to incur merger and integration charges and these charges have
been reflected in the pro forma book value per common share information below.
We also anticipate that the merger will provide the combined company with
financial benefits that include reduced operating expenses and the opportunity
to earn more revenue. The pro forma information throughout this document, while
helpful in illustrating the financial characteristics of the combined company
under one set of assumptions, does not reflect these expected reduced expenses
or expected revenue opportunities and, accordingly, does not attempt to predict
or suggest future results. It also does not necessarily reflect what the actual
historical results of the combined company would have been had our companies
been combined.

    The information in the following table should be read together with the
historical financial information that we have presented in our prior filings
with the SEC. We have incorporated this material into this document by reference
to those other filings. See "Where You Can Find More Information" on page 100.

SELECTED CONSOLIDATED HISTORICAL FINANCIAL DATA OF DIME

     The following table presents selected consolidated historical financial
data of Dime derived from Dime's previously filed financial statements. The
interim financial information at or for the nine months ended September 30, 1999
and September 30, 1998 has been derived from previously filed unaudited
financial statements of Dime. Dime believes that these financial statements
include all adjustments of a normal, recurring nature and all disclosures that
are necessary for a fair presentation of such financial statements at or for the
unaudited interim periods. Results for the interim periods do not necessarily
indicate results that may be expected for any other interim or annual period.

     This historical information does not include the acquisition by Dime
Savings Bank of 28 branches of KeyBank effective as of October 18, 1999. There
were no separate financial statements for the assets of KeyBank acquired, and
Dime does not believe that this acquisition presents a significant acquisition
in the context of Dime's historical financial data and under rules established
by the SEC.

     The information in the following table should be read together with the
historical financial information that Dime has presented in its prior filings
with the SEC. Dime has incorporated this material into this document by
reference to those other filings. See "Where You Can Find More Information" on

SELECTED CONSOLIDATED HISTORICAL FINANCIAL DATA OF HUDSON

     The following table presents selected consolidated historical financial
data of Hudson derived from Hudson's previously filed financial statements. The
interim financial information at or for the nine months ended September 30, 1999
and September 30, 1998 has been derived from unaudited financial statements of
Hudson. Hudson believes that these financial statements include all adjustments
of a normal, recurring nature and all disclosures that are necessary for a fair
presentation of such financial statements at or for the unaudited interim
periods. Results for the interim periods do not necessarily indicate results
that may be expected for any other interim or annual period.

     The previously filed financial statements from which this information was
derived include the financial statements presented in the Forms 8-K, filed by
Hudson on December 15, 1999 and January 28, 2000, which include supplemental and
restated financial information of Hudson reflecting the completion of the
acquisitions of JeffBanks and Southern Jersey Bancorp. Hudson information does
not include the completion of the acquisition of substantially all of the assets
of Lyon Credit Corporation that occurred on October 22, 1999 or the acquisition
of loans and other financial assets, and the assumption of deposits, of Advest
Bank and Trust that occurred on December 1, 1999. Hudson does not believe that
the Lyon Credit and Advest acquisitions present significant acquisitions in the
context of Hudson's historical financial data and under rules established by the
SEC.

     The information in the following table should be read together with the
historical financial information that Hudson has presented in its prior filings
with the SEC. Hudson has incorporated this material into this document by
reference to those other filings. See "Where You Can Find More Information" on
page 100.

UNAUDITED SELECTED PRO FORMA COMBINED FINANCIAL DATA OF DIME AND HUDSON

     The following table sets forth unaudited selected pro forma combined
financial data giving effect to the merger of Dime and Hudson under the
pooling-of-interests method of accounting, which assumes the merger was
completed on September 30, 1999 for balance sheet information and on January 1,
1996 for all other pro forma information. This pro forma information should be
read together with the adjustments and assumptions described in the "Notes to
Unaudited Pro Forma Combined Condensed Financial Information" on pages 96-98.

     We expect to incur merger and integration charges and these charges have
been reflected in the balance sheet information below. We also anticipate that
the merger will provide the combined company with financial benefits that
include reduced operating expenses and the opportunity to earn more revenue. The
pro forma information throughout this document, while helpful in illustrating
the financial characteristics of the combined company under one set of
assumptions, does not reflect these expected reduced expenses or expected
revenue opportunities and, accordingly, does not attempt to predict or suggest
future results. It also does not necessarily reflect what the actual historical
results of the combined company would have been had our companies been combined.

     This pro forma information reflects completion of the mergers of JeffBanks
and Southern Jersey Bancorp into Hudson; this pro forma information does not
include the completion of the acquisition by Dime Savings Bank of 28 branches of
KeyBank effective as of October 18, 1999; this pro forma information does not
include the completion of the acquisition by Hudson of substantially all of the
assets of Lyon Credit Corporation that occurred on October 22, 1999 or the
acquisition by Hudson of loans and other financial assets, and the assumption of
deposits, of Advest Bank and Trust that occurred on December 1, 1999.

     The information in the following table should be read together with the
historical financial information that we have presented in our respective prior
filings with the SEC. See "Where You Can Find More Information" on page 100.

                           FORWARD-LOOKING STATEMENTS

     This document contains a number of forward-looking statements regarding the
financial condition, results of operations and business of Dime, Hudson and Dime
United. These statements may be made directly in this document or may be
incorporated in this document by reference to other documents and may include
statements for the period following the completion of the merger. You can find
many of these statements by looking for words such as "believes," "expects,"
"anticipates," "estimates," "potential" or similar expressions. These
forward-looking statements involve substantial risks and uncertainties. Some of
the factors that may cause actual results to differ materially from those
contemplated by the forward-looking statements include, but are not limited to,
the following possibilities:

     - there may be increases in competitive pressure among financial
       institutions or from non-financial institutions;

     - changes in the interest rate environment may reduce interest margins or
       may adversely affect mortgage banking operations;

     - changes in deposit flows, loan demand or real estate values may adversely
       affect our business;

     - changes in accounting principles, policies or guidelines may cause our
       financial condition to be perceived differently;

     - general economic conditions, either nationally or in some or all of the
       states in which the combined company will be doing business, or
       conditions in securities markets, the banking industry or the mortgage
       banking industry, may be less favorable than we currently anticipate;

     - legislation or regulatory changes may adversely affect our business;

     - technological changes, including Year 2000 data system compliance issues,
       may be more difficult or expensive than anticipated;

     - combining the businesses of Dime and Hudson and retaining key personnel
       may be more difficult or more costly than we expect;

     - our revenues after the merger may be lower than we expect, or our
       operating costs may be higher than we expect;

     - expected cost savings from the merger may not be fully realized, may not
       be realized at all or may not be realized within the expected time frame;
       or

     - the timing and occurrence or non-occurrence of events may be subject to
       circumstances beyond our control.

     All subsequent written and oral forward-looking statements concerning the
merger or other matters addressed in this document and attributable to Dime or
Hudson or any person acting on their behalf are expressly qualified in their
entirety by the cautionary statements contained or referred to in this section.
Neither Dime nor Hudson undertakes any obligation to release publicly any
revisions to such forward-looking statements to reflect events or circumstances
after the date of this document or to reflect the occurrence of unanticipated
events.

RECENT DEVELOPMENTS -- FOURTH QUARTER AND YEAR-END 1999 RESULTS

     Dime.  On January 20, 2000, Dime reported its fourth quarter and 1999
full-year financial results. For the fourth quarter of 1999, Dime reported net
income of $62.3 million, or $0.56 per diluted share of Dime stock. For the year
1999, Dime reported net income of $239.8 million, or $2.13 per diluted share of
Dime stock. At December 31, 1999, Dime had consolidated assets of $23.9 billion,
consolidated deposits of $14.3 billion and consolidated stockholders equity of
$1.5 billion. A more detailed report of Dime's results can be found in a Form
8-K filed by Dime with the SEC on January 20, 2000. See "Where You Can Find More
Information" on page 100.

     Hudson.  On January 20, 2000, Hudson reported its fourth quarter and 1999
full-year financial results. Fourth quarter operating earnings were $30.3
million, or $0.57 per diluted share of Hudson stock. Hudson reported a net loss
of $17.6 million for the 1999 fourth quarter, which resulted from charges taken
related to the JeffBanks and Southern Jersey acquisitions. The charges consisted
of a $33.0 million pre-tax special provision for loan losses to conform the
reserve policies of the two institutions to those of Hudson and $37.2 million
pre-tax in merger-related restructuring charges. Net income for the full year
1999, including these special charges, was $69.3 million, or $1.30 per diluted
share of Hudson stock. These results do not reflect the benefit of cost savings
related to the JeffBanks and Southern Jersey acquisitions that are expected to
be realized with the computer conversions scheduled to occur in the first
quarter of 2000. At December 31, 1999, Hudson had consolidated assets of $9.7
billion, consolidated deposits of $6.5 billion and consolidated stockholders
equity of $519 million. A more detailed report of Hudson's results can be found

                              DIME SPECIAL MEETING

     THIS SECTION CONTAINS INFORMATION FROM DIME FOR DIME STOCKHOLDERS ABOUT THE
SPECIAL STOCKHOLDERS MEETING IT HAS CALLED TO CONSIDER AND ADOPT THE MERGER
AGREEMENT.

     We are mailing this document to you as a Dime stockholder on or about
February 9, 2000. Together with this document, we are also sending you a notice
of the Dime special meeting and a form of proxy that is solicited by our board
of directors. The special meeting will be held on March 15, 2000, at 10:00 a.m.
at Chelsea Piers, Pier 60, 23rd and Hudson River, New York, New York 10011.

MATTERS TO BE CONSIDERED

     The purpose of the Dime special meeting is to vote on the adoption of the
merger agreement.

     You may be asked to vote upon any other matters that may properly be
submitted to a vote at the special meeting. You may also be asked to vote on a
proposal to adjourn or postpone the special meeting. We could use any
adjournment or postponement for the purpose, among others, of allowing
additional time to solicit proxies.

                                       18

PROXIES

     You should complete and return the proxy card accompanying this document to
ensure that your vote is counted at the special meeting, regardless of whether
you plan to attend the special meeting. You can revoke your proxy at any time
before the vote is taken at the special meeting by

     - submitting written notice of revocation to the Corporate Secretary of
       Dime,

     - submitting a properly executed proxy of a later date, or

     - voting in person at the special meeting, but simply attending the special
       meeting without voting will not revoke an earlier proxy.

Written notices of revocation and other communications about revoking your proxy
should be addressed to:

                            Dime Bancorp, Inc.
                            589 Fifth Avenue
                            New York, NY 10017
                            Attention: Gene C. Brooks
                                       Corporate Secretary

If your shares are held in street name, you should follow the instructions of
your broker regarding revocation of proxies.

     All shares represented by valid proxies we receive through this
solicitation, and not revoked, will be voted in accordance with your
instructions on the proxy card. If you make no specification on your proxy card
as to how you want your shares voted before signing and returning it, your proxy
will be voted "FOR" adoption of the merger agreement. The board of directors is
presently unaware of any other matters that may be presented for action at the
special meeting. If other matters do properly come before the special meeting,
we intend that shares represented by properly submitted proxies will be voted,
or not voted, by and at the discretion of the persons named as proxies on the
proxy card. However, proxies that indicate a vote against adoption of the merger
agreement will not be voted in favor of adjourning or postponing the special
meeting to solicit additional proxies.

     DIME STOCKHOLDERS SHOULD NOT SEND STOCK CERTIFICATES WITH THEIR PROXY
CARDS. IF THE MERGER IS COMPLETED, DIME STOCKHOLDERS WILL BE MAILED A
TRANSMITTAL FORM WITH INSTRUCTIONS ON HOW TO EXCHANGE THEIR CURRENT STOCK
CERTIFICATES FOR STOCK CERTIFICATES OF DIME UNITED.

SOLICITATION OF PROXIES

     We will bear the entire cost of soliciting proxies from you, except that we
have agreed with Hudson that each of us will pay one-half of the costs and
expenses of preparing, printing and mailing this document and all filing and
other fees relating to the merger paid to the SEC. In addition to solicitation
of proxies by mail, we will request that banks, brokers and other record holders
send proxies and proxy material to the beneficial owners of Dime stock and
secure their voting instructions, if necessary. We will reimburse the record
holders for their reasonable expenses in taking those actions. We have also made
arrangements with Innisfree M&A Incorporated to assist us in soliciting proxies
and have agreed to pay them $9,000 plus reasonable expenses for these services.
If necessary, we may also use several of our regular employees, who will not be
specially compensated, to solicit proxies from Dime stockholders, either
personally or by telephone, telegram, facsimile or letter.

RECORD DATE

     In accordance with Delaware law, Dime's by-laws and the rules of the NYSE,
the close of business on February 4, 2000 has been fixed as the record date for
determining the Dime stockholders entitled to receive notice of and to vote at
the special meeting. At that time, 110,899,492 shares of Dime stock were
outstanding, held by 19,335 holders of record.

                                       19
<PAGE>   29

VOTING RIGHTS AND VOTE REQUIRED

     The presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of Dime stock is necessary to constitute a
quorum at the special meeting. Abstentions and broker non-votes will be counted
solely for the purpose of determining whether a quorum is present. Under the
applicable rules of the NYSE, brokers or members who hold shares in street name
for customers who are the beneficial owners of such shares are prohibited from
giving a proxy to vote those shares with respect to the merger without specific
instructions from such customers. An unvoted proxy submitted by a broker is
sometimes referred to as a broker non-vote.

     Adoption of the merger agreement requires the affirmative vote of the
holders of a majority of the outstanding shares of Dime stock entitled to vote
at the Dime special meeting. You are entitled to one vote for each share of Dime
stock you held as of the record date.

     BECAUSE THE AFFIRMATIVE VOTE OF THE HOLDERS OF A MAJORITY OF THE
OUTSTANDING SHARES OF DIME STOCK ENTITLED TO VOTE AT THE DIME SPECIAL MEETING IS
NEEDED FOR US TO PROCEED WITH THE MERGER, THE FAILURE TO VOTE BY PROXY OR IN
PERSON, ABSTENTIONS AND BROKER NON-VOTES WILL HAVE THE SAME EFFECT AS VOTES
AGAINST THE MERGER AGREEMENT. ACCORDINGLY, THE BOARD URGES DIME STOCKHOLDERS TO
COMPLETE, DATE AND SIGN THE ACCOMPANYING PROXY CARD AND RETURN IT PROMPTLY IN
THE ENCLOSED, POSTAGE-PAID ENVELOPE.

     As of the record date:

     - Directors and executive officers of Dime and their affiliates
       beneficially owned 2,812,958 shares of Dime stock, or 2.54% of the Dime
       stock outstanding on that date.

     - Directors and executive officers of Hudson and their affiliates
       beneficially owned 6,160 shares of Dime stock, or less than one percent
       of the Dime stock outstanding on that date.

     - Hudson beneficially owned 2,469,100 shares of Dime stock, or 2.23% of the
       Dime stock outstanding on that date, excluding the shares subject to the
       Dime stock option described in "The Stock Option Agreements" on pages
       68-70.

CONFIDENTIAL VOTING POLICY

     The board of directors of Dime has adopted a policy on confidential voting.
The policy provides that all proxies, ballots, and voting tabulations that
identify the vote of a particular stockholder be held in confidence by the
independent tabulators and inspectors of election and not disclosed to any other
person, including us and our directors, officers and employees, except in
certain limited circumstances, including:

     - as necessary to meet legal requirements or to pursue or defend legal
       actions;

     - to allow the inspectors of election to certify the results of the vote;

     - when expressly authorized by the stockholder;

     - in the event of a contested proxy solicitation; or

     - if a bona fide dispute exists regarding the authenticity of any proxy
       card or ballot or the accuracy of any tabulation of votes.

However, the policy permits disclosure of any comments or other information
written on any proxy card or ballot without reference to the vote of the
stockholder, except where such vote is included in, and necessary to an
understanding of, such written material.

RECOMMENDATION OF THE BOARD OF DIRECTORS

     The Dime board of directors has approved and declared advisable the merger
agreement and the transactions it contemplates. The Dime board of directors
believes that the merger agreement and the transactions it contemplates are fair
to Dime stockholders and are in the best interests of Dime and its stockholders
and recommends that you vote "FOR" the adoption of the merger agreement.

     HUDSON STOCKHOLDERS SHOULD NOT SEND STOCK CERTIFICATES WITH THEIR PROXY

EQUAL NUMBER OF SHARES OF DIME UNITED STOCK. HUDSON STOCKHOLDERS WILL NOT NEED
TO EXCHANGE THEIR STOCK CERTIFICATES UNLESS DIME AND HUDSON DETERMINE THAT AN
EXCHANGE IS LEGALLY REQUIRED, IN WHICH CASE WE WILL GIVE YOU INSTRUCTIONS ON HOW
TO EXCHANGE YOUR CERTIFICATES.

SOLICITATION OF PROXIES

     We will bear the entire cost of soliciting proxies from you, except that we
have agreed with Dime that each of us will pay one-half of the costs and
expenses of preparing, printing and mailing this document and all filing and

                                   THE MERGER

     The following discussion contains material information pertaining to the
merger. This discussion references the merger agreement, stock option agreements
and financial advisor opinions attached as Appendices to this document. We
encourage you to read and review those documents as well as the discussion in
this document.

GENERAL

     This section provides material information about the merger of Dime and
Hudson and the circumstances surrounding the merger. The next sections of this
document, entitled "The Merger Agreement" on pages 63-68 and "The Stock Option
Agreements" on pages 68-70, have additional and more detailed information
regarding the legal documents that govern the merger, including information
about the conditions to completion of the merger and the provisions for
terminating or amending the merger agreement.

     STRUCTURE

     The merger agreement provides for the merger of Hudson into Dime. Dime will
be the surviving corporation and will change its name to Dime United Bancorp,
Inc.

     Dime and Hudson have agreed to merge Dime Savings Bank into Hudson United
Bank and to rename the combined bank DimeBank. This bank merger will take place
simultaneously with the merger of Dime and Hudson. The merger of these banking
subsidiaries is subject to the regulatory approvals discussed in "Regulatory
Approvals Required for the Merger" on pages 53-55.

     Upon completion of the merger, Dime stockholders will receive 0.60255 of a
share of stock of Dime United for each share of Dime stock they hold. Dime
stockholders will receive cash instead of any fractional shares of Dime United
stock that would have otherwise been issued at the completion of the merger.
Fractional shares will be issued into Dime United's dividend reinvestment plan,
401(k) plan or other similar stock plans.

     Upon completion of the merger, Hudson stockholders will receive one share
of Dime United stock for each share of Hudson stock they hold, other than shares
owned by or for Hudson or Dime.

     If the number of shares of common stock of Dime or Hudson changes before
the merger is completed through a reorganization, recapitalization,
reclassification, stock dividend, stock split, reverse stock split, or other
similar event, then an appropriate and proportionate adjustment will be made to
the exchange ratios. The Dime exchange ratio has been increased from
0.585-for-1, as described in previously filed documents, because of the effect
of this provision in the merger agreement. The Dime exchange ratio was increased
because Hudson paid a 3% stock dividend on December 1, 1999 to Hudson
stockholders of record as of November 26, 1999.

                                       23
<PAGE>   33

     As a result of the merger, Dime stockholders immediately prior to the
merger will own 56%, and Hudson stockholders immediately prior to the merger
will own 44%, of the outstanding Dime United stock. These percentages are based
on the number of fully-diluted shares of Dime stock and Hudson stock calculated
as of September 15, 1999, after taking into account the exchange ratios.

     PUBLIC TRADING MARKETS

     Dime common stock is currently listed on the NYSE under the symbol "DME."
Hudson common stock is currently listed on the NYSE under the symbol "HU." Upon
completion of the merger, Hudson common stock will be delisted from the NYSE and
deregistered under the Securities Exchange Act. The authorization for listing on
the NYSE of the newly issued Dime United common stock issuable pursuant to the
merger agreement is a condition to the completion of the merger. It is currently
contemplated that the Dime United common stock will be listed on the NYSE under
the symbol "DU."

     The shares of Dime United stock to be issued in connection with the merger
will be freely transferable under the Securities Act, except for shares issued
to any stockholder who may be deemed to be an affiliate of Dime, Hudson or Dime
United, as discussed in "Resales of Dime United Stock by Affiliates" on page 53.

     The closing price per share of Dime stock on the NYSE on September 14,
1999, the last trading day prior to public announcement of the merger, was
$17 3/4. The closing price per share of Hudson stock on the NYSE on September
14, 1999 was $29 1/4, giving retroactive effect to Hudson's 3% stock dividend.
Based on these closing prices per share, and giving effect to the exchange
ratios, the implied per share value of Dime stock was $17.62 as of that date.
The closing price per share of Dime stock on the NYSE on February 7, 2000, the
last practicable trading day prior to the date of this document, was $13 1/8.
The closing price per share of Hudson stock on the NYSE on February 7, 2000, was
$22 1/4. The implied per share value of Dime stock was $13.41 as of that date.
The implied value of one share of Dime stock as of these dates was calculated by
multiplying Hudson's stock price by 0.60255. Because the stock prices of both of
our companies will fluctuate, you should obtain current quotations of these
prices.

     DIVIDEND POLICY OF DIME UNITED

     We currently contemplate that Dime United will pay cash dividends at an
annual rate of $1.00 per share, although the Dime United board of directors may
change this dividend policy at any time. During 1999, Hudson paid cash dividends
of $1.00 per share, before the impact of its 3% stock dividend, and Dime paid
cash dividends of $0.23 per share.

     Dime United stockholders will be entitled to receive dividends when and if
declared by the Dime United board of directors out of funds legally available
for dividends. The Dime United board of directors will periodically consider the
payment of dividends, taking into account Dime United's financial condition and
level of net income, Dime United's future prospects, economic conditions,
industry practices and other factors, including applicable banking laws and
regulations as discussed in "Regulation and Supervision of Dime United" on pages
82-86.

     ABSENCE OF APPRAISAL RIGHTS

     Appraisal rights are statutory rights that enable stockholders who object
to extraordinary transactions, such as mergers, to demand that the corporation
pay the fair value for their shares as determined by a court in a judicial
proceeding instead of receiving the consideration offered to stockholders in
connection with the extraordinary transaction. Appraisal rights are not
available in all circumstances and exceptions to such rights are set forth in
the laws of Delaware and New Jersey with respect to the rights of Dime
stockholders and Hudson stockholders, respectively.

     Dime stockholders are not entitled to appraisal rights under Delaware law
in connection with the merger because shares of Dime common stock are listed on
the NYSE and the Dime United stock will be listed on the NYSE. Delaware law
states that stockholders of a company whose stock is listed on a

                                       24
<PAGE>   34

national securities exchange are not entitled to appraisal rights if they
receive stock in a company whose stock is listed on a national securities
exchange.

     Hudson stockholders are not entitled to appraisal rights under New Jersey
law in connection with the merger because the shares of Hudson common stock are
listed on the NYSE. New Jersey law states that stockholders of a company whose
stock is listed on a national securities exchange are not entitled to appraisal
rights.

BACKGROUND OF THE MERGER

     Dime has periodically considered the possibility of various forms of
strategic combinations with a variety of financial institutions and has
evaluated the potential strategic fit with institutions based on their lines of
business, prospects, management and geographic location and concentration.

     Management of Hudson has, over time, regularly considered the possibility
of, and engaged in, acquisitions and strategic combinations with a variety of
financial institutions and financial services companies. In considering and
engaging in these transactions, Hudson has taken into account various factors,
including its potential strategic fit with these institutions based upon their
banking and financial services business, their customer profile and franchise,
their directors, management and employees and the geographic locations and
breadth or limits of their businesses. In light of recent trends regarding
consolidation and merger in the banking industry, the senior management of
Hudson has from time to time had informal discussions with senior management of
other larger and smaller financial institutions regarding potential business
combination transactions.

     On June 4, 1999, at a special meeting, the Hudson board of directors
determined, as it had on occasion in the past, to explore the company's
strategic alternatives while continuing its long-standing acquisition strategy.
Hudson engaged Goldman, Sachs & Co. to assist it in this regard. On June 28, as
part of its continuing long-term acquisition strategy, Hudson entered into two
separate merger agreements by which it would acquire JeffBanks, Inc. and
Southern Jersey Bancorp of Delaware, Inc.

     During the summer, Goldman Sachs approached a small number of entities
selected by Hudson, ranging in size from institutions substantially larger than
Hudson to institutions somewhat smaller than Hudson.

     In late July, Goldman Sachs contacted Dime on Hudson's behalf and inquired
as to whether Dime might be interested in a strategic combination involving
Hudson. On July 29, Goldman Sachs provided Dime with preliminary business and
financial information regarding Hudson. On August 10, Lawrence J. Toal,
Chairman, President and Chief Executive Officer of Dime, and Kenneth T. Neilson,
Chairman, Chief Executive Officer and President of Hudson, met at Dime's
corporate offices to discuss the possibility of a merger of equals between Dime
and Hudson.

     Throughout the remainder of August and early September, Mr. Toal and Mr.
Neilson, as well as their financial and legal advisors, continued discussions
relating to a strategic combination of Dime and Hudson and related issues,
including the possibility of a market-based merger of equals, as well as
governance considerations, including board representation and key senior
management positions.

     At the request of Hudson, Goldman Sachs prepared preliminary materials
about a potential merger of equals with Dime and provided these materials to the
entire Hudson board of directors during the last week of August.

     In August, Dime engaged Credit Suisse First Boston to act as its financial
advisor to assist Dime in reviewing the business and financial position of
Hudson and the feasibility of the proposed transaction. Additionally, Dime's
senior management continued its review of previously provided or otherwise
available information regarding Hudson. During the week of August 30, Dime also
requested that its legal counsel begin drafting documents related to the merger
and begin negotiating such documents and other terms of the merger with Hudson's
legal counsel.

     The Hudson board of directors and its Executive Committee held a series of
meetings during September to consider a potential merger with Dime. On September
3, the Executive Committee of Hudson met with Goldman Sachs and Hudson's legal
advisors to discuss a potential merger of equals with Dime. After extensive
discussion, the Executive Committee authorized management of Hudson to commence
a due diligence review of Dime to assist the Hudson board of directors in its
consideration of the potential merger. Hudson directed its legal advisors to
discuss with Dime's legal advisors the form of contract for a merger of equals
between Hudson and Dime. On September 6, legal counsel for Dime and Hudson began
discussions of a possible merger agreement. During the week of September 7,
representatives of Dime and Hudson met as part of a due diligence review of each
other's business.

     The Strategic Planning Committee of the Dime board of directors met on the
evening of September 7 and was advised of the status of the discussions between
Dime and Hudson. At that meeting, Credit Suisse First Boston gave a presentation
to the Dime Strategic Planning Committee regarding the financial and strategic
considerations of a possible merger of equals between Dime and Hudson and legal
counsel made a preliminary presentation with respect to the proposed
transaction. Additional meetings of the Dime Strategic Planning Committee were
held on September 9 and 10.

     On Thursday, September 9, the full Hudson board of directors met to hear
the results of the due diligence review to that date and the Hudson board of
directors engaged in extensive discussions concerning the business of Dime and
the structure of the transaction. Legal counsel to Hudson also summarized the
terms of the draft merger agreement that had been drafted by Dime's legal
counsel after discussions with Hudson's legal counsel. Following these
presentations and discussions, the members of the board were introduced to Mr.
Toal.

     The Dime board of directors met on September 10 to consider the proposed
merger. At this meeting the Dime Strategic Planning Committee recommended
consideration of the possible merger of equals to the full board of directors of
Dime. Also at this board meeting, Credit Suisse First Boston gave a detailed
analysis of the financial and strategic considerations of the merger, Dime
senior management reported on Dime's due diligence findings to date, and the
Dime board of directors engaged in a discussion of the reasons for entering into
this transaction. Legal counsel also made a presentation to the Dime board of
directors with respect to the terms of the proposed merger agreement. Following
these presentations and discussions, the members of the board were introduced to
Mr. Neilson.

     The Dime board of directors met again to discuss and review business,
strategic and financial issues regarding the possible business combination on
September 12 and 13. At the September 12 board meeting, Credit Suisse First
Boston presented the Dime board of directors with its updated financial analysis
of the proposed merger and gave its oral opinion as to the fairness, from a
financial point of view, as of such date, of the proposed Dime exchange ratio in
the merger to Dime stockholders. At this meeting, legal counsel updated the
board with respect to the status of negotiations of the merger agreement and
senior management presented the results of its due diligence review of the
business and financial position of Hudson. Also at this meeting and the meeting
on September 13, the Dime board of directors continued its discussion of the
various considerations in undertaking the proposed merger with Hudson as listed
in "Dime's Reasons for the Merger; Recommendation of Dime's Board of Directors"
on pages 27-32 of this document.

     During the day on September 13, the Executive Committee of Hudson again met
to discuss the terms of the merger proposal and authorized further negotiations
with Dime. The Hudson board of directors met again on the evening of September
13, but the Board did not consider the merger proposal because certain of the
proposed terms of the merger had not been finalized in accordance with the
Executive Committee's understanding. The Hudson board of directors met again on
the evening of September 14. At this meeting, a further and extensive
presentation regarding the results of the due diligence review of Dime was made
to the Hudson board of directors by the senior management of Hudson. Hudson
reviewed its discussions and negotiations with Dime regarding a business
combination. Goldman Sachs made a presentation to the Hudson board of directors
on financial aspects of the potential transaction, and Goldman Sachs rendered a
written opinion dated September 14 that the Hudson exchange ratio was fair to
Hudson stockholders from

                                       26
<PAGE>   36

a financial point of view. At the September 14 meeting, the Hudson board of
directors again discussed with counsel to Hudson the terms of the merger
agreement and the stock option agreements as well as Mr. Neilson's proposed
contract. After questions by and discussions among the members of the Hudson
board of directors, and after consideration of the factors described under the
caption "Hudson's Reasons for the Merger; Recommendation of Hudson's Board of
Directors" on pages 32-34, the Hudson board of directors voted to approve the
merger agreement and transactions contemplated thereby, as well as the stock
option agreements and Mr. Neilson's contract, and recommended approval of the
merger agreement to Hudson's stockholders.

     At the Dime board of directors meeting on September 14, Credit Suisse First
Boston again reviewed with the Dime board of directors its financial analysis
and reiterated its earlier oral opinion as to the fairness of the transaction to
Dime stockholders, and senior management and legal counsel gave the board of
directors a final briefing on the status of the merger agreement and related
documents. Following further discussion, the Dime board of directors voted to
approve and deem advisable the merger of Dime and Hudson, the merger agreement
and the stock option agreements, and to recommend the adoption of the merger
agreement to Dime's stockholders.

     Throughout the discussions between Dime and Hudson, the senior management
of each company consulted with its respective financial advisors to determine
the appropriate exchange ratios. The exchange ratios were a product of
arms-length negotiation between Dime and Hudson.

     Hudson and Hudson United Bank executed Mr. Neilson's employment agreement
as of September 14. Dime and Hudson executed the merger agreement prior to the
opening of business on the morning of September 15, and the stock option
agreements as of September 16. Announcement of the transaction was made on
September 15.

DIME'S REASONS FOR THE MERGER; RECOMMENDATION OF DIME'S BOARD OF DIRECTORS

     The Dime board of directors believes that the merger presents a unique
opportunity to combine and expand two complementary sets of banking operations
in attractive and contiguous markets in a four-state region that cover an area
from Philadelphia to Hartford. The board consulted with financial and other
advisors and determined that the merger was likely to accelerate the strategic
plans of Dime and was in the best interests of Dime and its stockholders. In
reaching its conclusion to approve the merger agreement, the stock option
agreements, and the transactions contemplated by those documents, the board
considered a number of factors, including those discussed below.

- - FINANCIAL CONSIDERATIONS

     - Market-based exchange ratio.  The board took into account that the
      exchange ratios for Dime stock and Hudson stock into Dime United stock
      were determined consistent with the market prices for the stock of each
      company and exchange ratios in other mergers of equals. In connection with
      this review, the board considered the relative contribution of earnings,
      assets, liabilities and equity of the two parties to the combined company.

     - Enhanced financial performance ratios.  The board took into consideration
      the expected significant improvement in Dime's key financial performance
      ratios, including return on assets and return on equity on both a reported
      basis and a cash operating earnings basis, net interest margin, and the
      efficiency ratio. These performance measures, on a pro forma basis for the
      quarter ended June 30, 1999, giving effect to the merger and all pending
      acquisitions, would show material improvement and would compare favorably
      to a peer group of banks selected by Credit Suisse First Boston, which
      included Charter One Financial Inc., GreenPoint Financial Corp., Peoples
      Heritage Financial

                                       27
<PAGE>   37

      Group Inc., North Fork Bancorporation Inc., TCF Financial Corp., and
      Associated Banc Corp. The following chart quantifies the factors presented
      to the board for consideration:

<TABLE>
<CAPTION>
                                                         PRO FORMA     BANK PEER

                                                ----    -----------    ---------
<S>                                             <C>     <C>            <C>
Net Interest Margin                             2.94%      3.38%         3.92%
Efficiency Ratio                                51.2%      42.0%         49.3%
Return on Assets                                1.15%      1.34%         1.40%
Return on Equity                                16.7%      19.9%         17.7%
Cash Return on Assets                           1.22%      1.44%         1.61%
Cash Return on Equity                           23.5%      28.3%         24.2%
</TABLE>

       Management of Dime and Hudson have established the following goals for
       the performance ratios of Dime United: a net interest margin greater than
       4.00%, an efficiency ratio less than 45%, a return on assets greater than
       1.5%, a return on equity greater than 20% and earnings per share growth
       greater than 12%. Because these represent "goals" developed by management
       and because management set no time table for attaining them, we cannot be
       certain that they will in fact be achieved or on what schedule any
       realization of these goals may occur.

     - Cost savings.  The board observed that the synergies expected from the
       merger should result in expense reductions. In making this determination,
       fully phased-in annual pre-tax expense reductions of $78 million,
       representing an estimated 8.6% of the combined company's expenses and an
       estimated 13.7% of the combined company's expense base excluding mortgage
       banking operations, were identified by management following a due
       diligence review of the businesses of Dime and Hudson. These cost saving
       actions were expected to result in the achievement of $38 million in cost
       savings for the year 2000 and $78 million for the year 2001. Of the
       anticipated year 2001 pre-tax expense reductions, $42 million is
       associated with personnel costs, largely reflecting the expected
       elimination of approximately 550 positions, and $14 million is associated
       with the elimination of redundant facilities, equipment and systems. The
       remaining $22 million of cost savings are expected to be achieved through
       reductions in various general and administrative expense categories,
       primarily marketing, regulatory assessments as a result of the
       relinquishment by Dime Savings Bank of its thrift charter, and
       professional fees.

     - Revenue enhancements.  The board took note that the complementary nature
       of the respective geographic markets, business products and skills of
       Dime and Hudson should result in enhanced revenue opportunities as
       products are cross-marketed and distributed over broader geographic and
       customer bases. Management of Dime and Hudson have identified revenue
       enhancement initiatives of approximately $20 million annually, although
       we cannot be certain that such revenue enhancements will in fact be
       achieved or on what schedule any initiatives may be undertaken.

     - Improved price-to-earnings multiple of Dime United stock.  The board
       analyzed the historical and current market prices of Hudson stock and
       believed that the combination could result in an increase in the
       price-to-earnings multiple at which Dime stock currently trades. In
       addition, the board assessed the prospects for continued improvement in
       the price-to-earnings multiple trading range of Dime United stock as a
       result of the anticipated transition toward a commercial banking
       enterprise, greater earnings diversification and other factors. The board
       considered September 10, 1999 price-to-earnings multiples, the most
       recent information available to the board at the time. In this regard,
       the board took note of the average price-to-earnings multiple of a
       commercial bank peer group identified by Credit Suisse First Boston,
       which reflected stock valuations in excess of Dime's by 37%, based on
       year 2000 earnings estimates. After the announcement of the transaction,
       management of Dime and Hudson jointly analyzed various scenarios
       regarding potential growth in price-to-earnings multiples on a pro forma
       basis. In investor presentations given after September 15, 1999,
       management of Dime and Hudson discussed the potential value that might be
       created for stockholders by expansion of Dime United's price-to-earnings
       multiple. For the purpose of the investor presentations, management of
       Dime and Hudson analyzed a peer group of banks that

                                       28
<PAGE>   38

       included Associated Banc Corp., M&T Bank Corp., North Fork Bancorporation
       Inc. and Summit Bancorp. Using market data as of September 14, 1999 and
       fully phasing-in anticipated cost savings from the merger, management of
       Dime and Hudson presented the following analysis:

<TABLE>
<CAPTION>
                                                        PRO FORMA                           POTENTIAL
                     IMPLIED MULTIPLE TO:              DIME UNITED   BANK PEER GROUP   IMPLIED VALUE GROWTH

         1999 Estimated Earnings Per Share...........      8.5x           13.0x                 54%
         2000 Estimated Earnings Per Share...........      7.7x           11.8x                 53%
         Book Value..................................     1.69x           2.39x                 41%
         Tangible Book Value.........................     2.39x           3.16x                 32%
</TABLE>

      The potential implied value growth figures are the product of calculating
      the mathematical difference between the pro forma Dime United multiples
      and the corresponding multiples for the bank peer group. These
      calculations were presented for informational purposes in considering
      potential outcomes; in deciding how to vote, you should not assume that
      potential growth will occur in terms of these multiples.

     - Effect on earnings per share.  The board noted that the merger should be
       modestly accretive to earnings per share by 2001, upon realization of
       identified cost savings. In assessing this earnings accretion, the board
       noted that no revenue enhancements were assumed.

     - Hudson's past performance.  The board assessed the strength of Hudson's
       financial performance on a stand-alone basis and Hudson's ability to
       maintain superior profitability even during the integration of various
       acquisitions over the past several years.

     - Financial strength.  The board considered the expected financial strength
       of Dime United, including its ability to realize enhanced returns on
       capital and to take advantage of various business opportunities with
       greater financial resources.

     - Credit Suisse First Boston opinion.  The board evaluated the detailed
       financial analyses and presentation of Credit Suisse First Boston as well
       as its opinion that, based on and subject to the considerations set forth
       in the opinion, the Dime exchange ratio is fair from a financial point of
       view to Dime stockholders. See "Opinion of Dime's Financial Advisor" on
       pages 34-40.

- - STRATEGIC CONSIDERATIONS

     - Transformation to commercial bank.  The board considered the strategic
       implications of combining Dime Savings Bank, which is a federal savings
       bank or thrift, into a commercial bank. Specifically, the board took into
       account:

       --  Dime's long-term strategy to shift from a traditional savings
           association to a more commercial bank-like profile and that the
           combination with a commercial bank such as Hudson would accelerate
           this strategy;

       --  that the proposed merger would result in an immediate change in
           Dime's loan mix, so that, after the merger is completed and based on
           June 30, 1999 information available to the board, relatively
           higher-yielding commercial real estate, business and consumer loans
           are expected to increase from approximately 36% to 48% of total loans
           receivable, and relatively lower-yielding residential mortgage loans
           are expected to decrease from approximately 64% to 52% of total loans
           receivable;

       --  that the proposed merger is expected to improve profitability ratios
           and potentially enhance Dime's price-to-earnings stock trading
           multiple, as discussed above under "Financial Considerations"; and

       --  the regulatory issues related to becoming a bank holding company and
           conducting banking operations through a commercial bank.

                                       29
<PAGE>   39

     - Attractive markets.  The board noted the complementary and compatible
      nature of Dime's and Hudson's contiguous geographic markets, which it
      believed to present a desirable strategic opportunity for geographic
      expansion and diversification. In particular, the board considered that:

       --  the combination of the two businesses will provide Dime with broader
           coverage in its traditional market, the greater New York City
           metropolitan area;

       --  the merger presents Dime with the ability to enter into attractive
           neighboring markets, including Connecticut, Southern New Jersey and
           the greater Philadelphia metropolitan area; and

       --  the resulting institution's branch network and franchise would be
           concentrated in one of the most affluent and populous regions in the
           country.

     - Complementary businesses and skills.  The board took into consideration
      that the businesses and skills of Hudson would augment those of Dime. In
      particular, the board considered that Hudson would:

       --  contribute businesses and skills beyond those currently present at
           Dime, including a broader focus on commercial banking, trust
           services, and a private label credit card program; and

       --  add to Dime's strengths in residential and consumer lending, mortgage
           banking services, and deposit taking, as well as automobile
           financing.

     - Earnings diversification.  The board noted that the combination of Hudson
      and Dime would continue the process of balancing and diversifying Dime's
      businesses, thereby decreasing the percentage of earnings attributable to
      mortgage banking from 25% to 13% of overall earnings. In making its
      determination, the board considered the relatively volatile nature of
      earnings derived from mortgage banking and the stock market reaction to
      that volatility.

     - Wider product distribution.  The board considered that there would be
      expected revenue and other business and customer enhancements from a wider
      distribution base in the combined company's core market for Dime products
      and a nationwide distribution base for selected Hudson products.

     - Ability to integrate.  The board took note of the integration
      capabilities of Dime and Hudson. In this regard, the board evaluated
      several key factors, including:

       --  that customer disruption from branch closings or consolidations in
           the transition phase should not be significant due to the limited
           overlap and complementary nature of the markets served by Dime and
           Hudson;

       --  that the combined company would benefit from the strong management
           teams of each of Dime and Hudson and that, because a number of key
           senior management positions had already been decided, management
           would be better able to focus on integration early in the process;
           and

       --  the records of both Dime and Hudson in integrating acquisitions
           smoothly while retaining profitability, Dime having participated in
           the successful merger of equals with Anchor Bancorp, Inc. in early
           1995 and completed several acquisitions since that date, and Hudson
           having acquired 20 banking institutions since 1990.

     - Continuity.  The board considered the ability of Dime to retain
      continuity of management and of corporate structure, including retention
      of directors and the chief executive officer position, as well as its
      governing documents.

     - Greater financial resources.  The board considered that Dime United would
      have greater resources and broader product offerings, enabling it to
      capitalize on various business opportunities and to provide expanded
      services to its customer base.

     - Pooling-of-interests accounting.  The board took note of the probability
      of the elimination of pooling-of-interests accounting by early 2001 and
      the advantages of undertaking a pooling-of-

                                       30
<PAGE>   40

      interests transaction prior to this elimination. In making its
      determination, the board believed that finding a reasonable acquisition
      transaction that would put Dime in a similar strategic position as the
      proposed merger with Hudson prior to this development would be unlikely.

- - GENERAL CONSIDERATIONS

     c Due diligence.  The board considered the reports of management and
       outside advisors concerning the operations, financial condition and
       prospects of Hudson.

     c Strategic merger of equals.  The board reviewed the terms of the merger
       agreement and the stock option agreements, including the strategic
       merger-of-equals concept, which provides for reciprocal representations
       and warranties, conditions to closing and termination rights. In
       addition, the board compared the terms and resulting management structure
       of the merger with those of other recent mergers of this type.

     c Stock prices.  The board weighed the historical and current market prices
       of Dime stock and Hudson stock.

     c Dime's Goodwill Lawsuit.  Dime's board of directors also considered the
       value of its goodwill lawsuit against the US government in the context of
       a pooling-of-interests merger with Hudson. A detailed discussion of
       Dime's claim against the government is provided in Dime's Annual Report
       on Form 10-K for the year ended December 31, 1998. See "Where You Can
       Find More Information" on page 100. Specifically, the board examined,
       among other things:

      -- the inherent uncertainties involved in any litigation;

      -- the history of Dime's claim against the US government, noting that the
         basis of Dime's claim related to the write off of approximately $560
         million, consisting of:

        M $518 in supervisory goodwill;

        M $42 million in other contractual regulatory capital; and

        M until 1991, Dime's claim also included an additional $157 million

          and Loan Insurance Corporation;

      -- the litigation award ordered to be paid to Glendale Federal Bank, FSB
         in a similar goodwill lawsuit, which is currently under appeal, and in
         similar lawsuits by other banks. Glendale Federal wrote off
         approximately $475 million of supervisory goodwill and the court
         ordered the US government to pay $909 million in restitution and
         non-overlapping reliance damages to Glendale Federal; and

     The Dime board of directors realizes that there can be no assurance about
future results, including results expected or considered in the factors listed
above, such as assumptions regarding price-to-earnings multiples, potential
revenue enhancements, anticipated cost savings and earnings accretion. However,
the board concluded that the potential positive factors outweighed the potential
risks of consummating the merger.

     This discussion of information and factors considered by the Dime board of
directors is not intended to be exhaustive, but includes all material factors
considered by the board. The board did not assign specific weights to the
foregoing factors and individual directors may have given different weights to
different factors. After consideration of these factors, the board concluded
that the merger, the merger agreement and the stock option agreements were in
the best interests of Dime and its stockholders, and they authorized and
approved the merger agreement, the merger, the stock option agreements, and the
transactions contemplated thereby and recommended that Dime stockholders adopt
the merger agreement.

other information presented in this section is forward-looking in nature and,

     THE DIME BOARD OF DIRECTORS BELIEVES THAT THE MERGER IS FAIR TO, AND IN THE
BEST INTERESTS OF, DIME AND ITS STOCKHOLDERS. ACCORDINGLY, THE DIME BOARD OF
DIRECTORS RECOMMENDS THAT DIME STOCKHOLDERS VOTE "FOR" THE ADOPTION OF THE
MERGER AGREEMENT.

HUDSON'S REASONS FOR THE MERGER; RECOMMENDATION OF HUDSON'S BOARD OF DIRECTORS

     The Hudson board of directors believes that the consummation of the merger
presents a unique opportunity to combine two strong franchises to create a
premier banking and financial services company with a presence in New York City
and Long Island with a commitment and the resources to significantly enhance
shareholder value.

     In reaching its decision to approve the merger agreement and the stock
option agreements, the Hudson board of directors consulted with management of
Hudson, as well as with its financial and legal advisors, and considered a
variety of factors, including the following:

     - Their familiarity with and review of the business, operations, financial
       condition, earnings and prospects of each of Hudson and Dime. In making
       its determination, the Hudson board of directors took into account the
       results of Hudson's due diligence review of Dime's businesses.

     - Their knowledge and analysis of the current financial services industry
       environment, characterized by

       c rapid consolidation,

       c the proposed end of pooling-of-interests accounting, which has been a
         significant factor in Hudson's larger acquisitions,

       c increased opportunities for cross-industry expansion, possibly
         facilitated by proposed financial institution reform legislation, and

       c the need to anticipate, and best position Hudson in light of, industry
         trends.

     - Their belief that a combination of Hudson and Dime will enhance the
       combined company's financial profile, locally and nationally, and will
       expand its banking franchise to serve a significantly greater number of
       customers, recognizing the benefits associated with Dime's franchise in
       New York City and Long Island, as well as Dime's provision of mortgage
       banking services throughout the United States.

     - Their evaluation of the financial terms of the merger-of-equals structure
       and the effect of those financial terms on the Hudson stockholders,
       including:

       c the exchange terms, which provided basically for an exchange at market
         prices, and

       c the potential benefit to Hudson stockholders of the pro forma earnings
         per share accretion of between 32% and 40% from the merger, weighed
         against the offsetting detriment, which will occur to the extent that
         Dime United's stock trades at a lower price-to-earnings multiple than
         the multiple at which Hudson's stock has historically traded. While
         price-to-earnings multiples fluctuate over time and no assurances can
         be given as to the price-to-earnings multiple for Dime United at any
         time, the Hudson board of directors believed it likely that the Dime
         United stock would trade at a price-to-earnings multiple somewhere
         between the historical price-to-earnings multiples of Hudson and of
         Dime, and that, over time the price-to-earnings multiple of Dime United
         stock would expand to a higher commercial bank multiple. The board was
         informed by Goldman, Sachs & Co., its financial advisor, that as of
         September 10, 1999, Dime common stock was trading at a multiple of 6.8
         times Dime's I/B/E/S estimated 2001 earnings and Hudson common stock
         was trading at a multiple of 10.2 times Hudson's I/B/E/S estimated 2001

                                       32
<PAGE>   42

         earnings. The Board noted Goldman Sachs' calculation, based on
         assumptions including that the I/B/E/S estimates would be borne out,
         that in 2001 Hudson would experience pro forma earnings per share
         accretion of 40% and Hudson would experience pro forma share price
         appreciation of 40.4% if the combined company traded at Hudson's
         multiple of 10.2 times estimated 2001 earnings, pro forma share price
         appreciation of 9.3% if the combined company traded at a blended
         multiple (weighted according to the relative earnings contributions of
         the two entities) of 8.0 times estimated 2001 earnings, and pro forma
         share price depreciation of (7.0%) if the combined company traded at
         Dime's multiple of 6.8 times estimated 2001 earnings.

     - Their belief that the financial terms of the proposed merger are fair to
       and in the best interests of Hudson and Hudson stockholders and are
       consistent with Hudson's long-term strategy.

     - The scale, scope, strength and diversity of operations, product lines and
       delivery systems that could be achieved by combining Hudson and Dime, as
       illustrated by the fact that, based on information available as of the
       date of the merger agreement, Dime United:

       c would be the 35th largest bank holding company in the United States
         measured by total assets and with total assets of $32 billion on a pro
         forma basis one of the larger bank holding companies based in the
         Mid-Atlantic region,

       c could deliver financial products through over 340 branches in four
         states, and

       c would have scale in most of its business lines.

     - The opportunity to leverage each of Hudson's and Dime's products and
       lines of business over a larger consumer and business customer base.

     - The potential benefits from the combined company having greater depth of
       management talent than either Hudson or Dime would have on its own.

     - The possibility of achieving significant expense savings and operating
       efficiencies through, among other things, the elimination of duplicate
       efforts. The Hudson board of directors noted that, although no assurances
       could be given that any particular level of expense savings and operating
       efficiencies will be achieved, the managements of Dime and Hudson had
       identified potential cost savings of $78 million annually, with 50%
       expected to be achieved in 2000 and 100% expected to be achieved by the
       end of 2001.

     - The structure of the merger and the terms of the merger agreement and the
       stock option agreements, which are reciprocal in nature, including the
       fact that the exchange ratio provides certainty as to the number of
       shares of Dime United stock to be issued in the merger, and that the
       merger is intended to qualify as a transaction of a type that is
       generally tax-free for federal income tax purposes and as a pooling of
       interests for accounting purposes.

     - The non-financial terms of the merger agreement and related agreements,
       including that:

       c 12 members of the Hudson board of directors and 13 members of the Dime
         board of directors will comprise the boards for both Dime United and
         DimeBank,

       c Mr. Neilson will serve as President and Chief Operating Officer of Dime
         United and DimeBank,

       c Mr. Neilson is to become Chairman and Chief Executive Officer of Dime
         United and DimeBank at year-end 2002, or sooner if Mr. Toal no longer
         occupies those positions,

       c the terms of the corporate succession will be set forth in the Dime
         United certificate of incorporation,

       c Dime United will be a bank holding company, and

       c the new name of the combined company will be Dime United Bancorp, Inc.

     - The opinion of Goldman Sachs to the Hudson board of directors that, based
       on and subject to the considerations set forth in the opinion, the Hudson
       exchange ratio is fair from a financial point of view to Hudson
       stockholders. See "Opinion of Hudson's Financial Advisors" on pages
       40-47.

     - Their understanding that consummation of the merger depends on various
       factors, a number of which will be beyond its control, including the
       regulatory environment, economic conditions and unanticipated changes in
       business conditions.

     This discussion of the information and factors considered by the Hudson
board of directors is not intended to be exhaustive, but includes all material
factors considered by the Hudson board of directors. In reaching its
determination to approve and recommend the merger, the Hudson board of directors
did not assign any relative or specific weights to these factors, and individual
directors may have given differing weights to different factors. It should be
noted that this explanation of the Hudson board's reasoning is forward-looking
in nature and, therefore, should be read in light of the factors discussed under
the heading "Forward-Looking Statements" on page 16.

     THE HUDSON BOARD OF DIRECTORS BELIEVES THAT THE MERGER IS FAIR TO, AND IN
THE BEST INTERESTS OF, HUDSON AND ITS STOCKHOLDERS. ACCORDINGLY, THE HUDSON
BOARD OF DIRECTORS HAS APPROVED THE MERGER AGREEMENT AND RECOMMENDS THAT HUDSON
STOCKHOLDERS VOTE "FOR" APPROVAL OF THE MERGER AGREEMENT.

OPINION OF DIME'S FINANCIAL ADVISOR

     Credit Suisse First Boston acted as financial advisor to Dime in connection
with the merger. Dime selected Credit Suisse First Boston based on its
experience, expertise and familiarity with Dime and its business. Credit Suisse
First Boston is an internationally recognized investment banking firm and is
regularly engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, leveraged buyouts, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes.

     In connection with Credit Suisse First Boston's engagement, Dime asked
Credit Suisse First Boston to evaluate the fairness of the Dime exchange ratio
to Dime stockholders from a financial point of view. At the September 12, 1999
meeting of the Dime board of directors, Credit Suisse First Boston rendered to
the Dime board of directors an oral opinion that, as of September 12, 1999, and
based upon and subject to various matters stated in its opinion, the Dime
exchange ratio was fair to Dime stockholders from a financial point of view.
Credit Suisse First Boston has confirmed this oral opinion by delivery of a
written opinion dated September 15, 1999, the date the merger agreement was
signed, and updated as of the date of this document. The written opinion dated
as of the date of this document is sometimes referred to as the Credit Suisse
First Boston Opinion. In delivering the Credit Suisse First Boston Opinion,
Credit Suisse First Boston updated selected analyses it performed in connection
with its September 12, 1999 oral opinion and reviewed the assumptions on which
those analyses were based and the factors considered in connection with those
analyses.

     On November 16, 1999, Hudson announced a 3% common stock dividend, payable
December 1, 1999 to stockholders of record on November 26, 1999. As a result of
this dividend, the Dime exchange ratio was increased from 0.585-for-1 to
0.60255-for-1, pursuant to the antidilution provisions of the merger agreement.
This adjustment to the Dime exchange ratio did not affect Credit Suisse First
Boston's analyses because the adjustment did not affect the relative economic
interests of either the Dime or the Hudson stockholders.

     We have attached the full text of the Credit Suisse First Boston Opinion,
which describes the procedures followed, assumptions made, matters considered
and limitations on the review undertaken in connection with that opinion, as
Appendix D to this document. Dime stockholders should read the entire Credit
Suisse First Boston Opinion.

     Credit Suisse First Boston has consented to the inclusion of the Credit
Suisse First Boston Opinion as Appendix D and has reviewed and consented to the
inclusion of this disclosure related to the Credit Suisse
                                       34

First Boston Opinion. In giving this consent, Credit Suisse First Boston does
not admit that it comes within the category of persons whose consent is required
under Section 7 of the Securities Act or the rules and regulations of the SEC
under the Securities Act, nor does Credit Suisse First Boston admit that it is
an expert with respect to any part of the registration statement of which this
document is a part within the meaning of the term "experts" as used in the
Securities Act or the rules and regulations of the SEC under the Securities Act.

     The Credit Suisse First Boston Opinion is directed to the Dime board of
directors. It relates only to the fairness of the Dime exchange ratio to Dime
stockholders from a financial point of view, does not address any other aspect
of the merger or any related transaction and does not constitute a
recommendation to Dime stockholders as to how to vote at the Dime special
meeting. The summary of the Credit Suisse First Boston Opinion in this document
is qualified in its entirety by reference to the full text of that opinion.

     In arriving at its opinion, Credit Suisse First Boston:

     - reviewed the merger agreement and publicly available business and
       financial information relating to Hudson and Dime that it considered
       relevant;

     - reviewed other information relating to Hudson and Dime, including
       internal financial forecasts for 1999 and forecasts of cost savings to be
       achieved in the merger, provided by Hudson and Dime;

     - met with Dime's management to discuss the business and prospects of Dime;

     - considered financial and stock market information about Hudson and Dime
       and compared that information with similar information about other
       publicly held companies in similar businesses;

     - considered the financial terms of other recent business combinations and
       transactions; and

     - considered other information, financial studies, analyses and
       investigations and financial, economic and market criteria that Credit
       Suisse First Boston deemed relevant.

     In connection with its review, Credit Suisse First Boston did not assume
any responsibility for independent verification of any of the information
provided to or otherwise reviewed by Credit Suisse First Boston. Credit Suisse
First Boston relied on this information being complete and accurate in all
material respects. As to the financial forecasts, including the estimates of
future cost savings and operating synergies expected to be achieved as a result
of the merger, Credit Suisse First Boston assumed that these forecasts were
reasonably prepared and reflected the best currently available estimates and
judgments of the managements of Hudson and Dime as to the future financial
performance of Hudson and Dime. In addition, Dime did not ask Credit Suisse
First Boston to make, and Credit Suisse First Boston did not make, an
independent evaluation or appraisal of the assets or liabilities, contingent or
otherwise, of Hudson or Dime, nor was Credit Suisse First Boston furnished with
any evaluations or appraisals of this kind. Dime placed no limits on the scope
of analysis performed, or opinion expressed, by Credit Suisse First Boston.

     Credit Suisse First Boston's opinion was necessarily based upon financial,
economic, market and other conditions as they existed and could be evaluated on
the date of the opinion. Credit Suisse First Boston did not express any opinion
as to the actual value of Dime United stock when issued to Dime stockholders in
the merger or the prices at which the Dime United stock will trade.

     In preparing its opinion, Credit Suisse First Boston performed a variety of
financial and comparative analyses, the material aspects of which are described
below. The preparation of a fairness opinion is a complex analytic process
involving various determinations as to the most appropriate and relevant methods
of financial analyses and the application of those methods to the particular
circumstances. Therefore, such an opinion is not readily susceptible of summary
description. In arriving at its opinion, Credit Suisse First Boston made
qualitative judgments as to the significance and relevance of each analysis and
factor considered by it. Accordingly, Credit Suisse First Boston believes that
its analyses must be considered as a

                                       35
<PAGE>   45

whole and that selecting portions of its analyses and factors, without
considering all analyses and factors, could create a misleading or incomplete
view of the processes underlying its analyses and the Credit Suisse First Boston
Opinion.

     In its analyses, Credit Suisse First Boston made numerous assumptions with
respect to Hudson, Dime, industry performance, and regulatory, general business,
economic, market and financial conditions and other matters, many of which are
beyond the control of Hudson and Dime. No company, transaction or business used
in these analyses as a comparison is identical to Hudson, Dime or the merger.

     Moreover, an evaluation of the results of these analyses is not entirely
mathematical; rather, these analyses involve complex considerations and
judgments concerning financial and operating characteristics and other factors
that could affect the transaction, public trading or other values of the
companies, business segments or transactions being analyzed. The estimates
contained in these analyses and the ranges resulting from any particular
analysis are not necessarily indicative of actual values or predictive of future
results or values, which may be significantly more or less favorable than those
suggested by these analyses. In addition, analyses relating to the value of
businesses or securities do not purport to be appraisals or to reflect the
prices at which those businesses or securities actually may be sold.
Accordingly, these analyses and estimates are inherently subject to substantial
uncertainty.

     The Credit Suisse First Boston Opinion and the financial analyses Credit
Suisse First Boston presented to the Dime board of directors were among many
factors considered by the Dime board of directors in its evaluation of the
merger and should not be viewed as determinative of the views of the Dime board
of directors or management of Dime with respect to the Dime exchange ratio or
the merger.

     The following is a summary of the material financial analyses performed by
Credit Suisse First Boston in connection with its oral opinion rendered to the
Dime board of directors on September 12, 1999. Certain of these summaries
include information presented in tabular format. In order to fully understand
the financial analyses used by Credit Suisse First Boston, these tables must be
read together with the accompanying narrative. The tables alone do not
constitute a complete description of the applicable financial analysis.

     Unless otherwise noted, all multiples and ratios in the following analyses
were calculated using stock market data as of September 10, 1999 and financial
data as of or for the twelve-month period ended June 30, 1999. All estimates of
future earnings were based on consensus earnings per share estimates published
by either I/B/E/S International Inc. or First Call. I/B/E/S is an industry
service provider of global earnings information based on an average of earnings
estimates published by selected research analysts regarding companies of
interest to institutional investors. First Call is an industry service provider
of global earnings information based on an average of earnings estimates
published by various investment banking firms.

     Comparable Companies Analysis.  Credit Suisse First Boston compared
selected operating and stock market data for each of Dime and Hudson to
corresponding data for peer companies that Credit Suisse First Boston selected
and deemed to be relevant for this purpose based on their financial, operational
and other characteristics. The Dime peer group consisted of:

     - Astoria Financial Corp.

     - Sovereign Bancorp Inc.

     - Bank United Corp.

     - Roslyn Bancorp Inc.

     - Washington Mutual, Inc.

                                       36
<PAGE>   46

     The Hudson peer group consisted of:

     - Charter One Financial Inc.

     - GreenPoint Financial Corp.

     - Peoples Heritage Financial Group Inc.

     - North Fork Bancorporation Inc.

     - TCF Financial Corp.

     - Associated Banc Corp.

     The following table compares selected information derived by Credit Suisse
First Boston for Dime with corresponding data for its peer group. Historical
profitability and capital ratios for Dime and its peer group were calculated
based on operating results and financial condition data as of and for the three
months ended June 30, 1999. Credit Suisse First Boston also performed this
analysis for Dime on an adjusted basis to normalize Dime's capital levels with
the average capital levels of its peer group. For this purpose Credit Suisse
First Boston assumed that Dime had an additional $275 million of common equity
and generated additional pre-tax earnings on the incremental common equity at an
annual rate of 6%. Credit Suisse First Boston noted that on an adjusted basis
Dime would trade within the ranges of its peer group and slightly below the peer
group averages based on multiples to estimated earnings and stated book value.

     Credit Suisse First Boston also noted that approximately 25% of Dime's
revenues in the fiscal quarter ended June 30, 1999 was derived from Dime's
mortgage banking operations and that these revenues were subject to potential
volatility in a rising interest rate environment.

</TABLE>

     Credit Suisse First Boston also analyzed the theoretical value of Dime's
pending lawsuit against the U.S. government regarding the elimination of
supervisory goodwill. Credit Suisse First Boston noted that the potential
recovery in the lawsuit had a theoretical market value of up to $94 million
based on the trading prices of securities issued by California Federal Bank,
Coast Federal Savings Bank and Glendale Federal Bank, which were based on
anticipated recoveries in similar lawsuits. Credit Suisse First Boston also
noted, however, that this amount represented less than 5% of Dime's current
market capitalization and accordingly was not a material factor in a valuation
of Dime stock.

     Discounted Cash Flow Analysis.  Credit Suisse First Boston analyzed the
range of values of a share of each of Dime stock and Hudson stock implied by the
dividends per share that could be paid based on earnings per share projected
over a five-year period and by the theoretical value of a share of Dime stock
and Hudson stock at the end of the five-year period. Credit Suisse First Boston
based the projected earnings per share of Dime stock and Hudson stock on
consensus earnings per share estimates, as reported by I/B/E/S, for 1999 and
2000, excluding non-core net income items, and on the consensus long-term growth
rate for Dime's and Hudson's earnings per share, as reported by I/B/E/S, for
2001 through 2005. Earnings were adjusted to reflect an assumed constant ratio
of tangible common equity to assets that Credit Suisse First Boston viewed as
appropriate (5.50% in the case of both Dime and Hudson). Based on these
assumptions, Credit Suisse First Boston determined the theoretical value of a
share of Dime stock and Hudson stock at the end of the five-year period by
applying terminal multiples and discount rates that Credit Suisse First Boston
viewed as appropriate for companies with Dime's and Hudson's respective risk
characteristics. This analysis showed implied values per share of Dime stock
between $18.30 and $23.35 and values per share of Hudson stock between $29.65
and $36.74. Credit Suisse First Boston noted that the closing prices of Dime
stock and Hudson stock on September 10, 1999 were $18.125 and $31.50,
respectively.

     The discounted cash flow analysis for Dime is summarized in the chart
below:

</TABLE>

     Credit Suisse First Boston noted that the modest discount at which Dime's
stock traded compared to its theoretical discounted cash flow valuation appeared
to reflect the potential volatility of Dime's mortgage banking earnings streams,
particularly in the then current uncertain interest rate environment.
Accordingly,

                                       38

Credit Suisse First Boston indicated that the discounted cash flow valuation
results were consistent with its conclusions as to the fairness of the Dime
exchange ratio.

     Contribution Analysis.  Credit Suisse First Boston analyzed the relative
contribution to selected pro forma financial measures that Dime and Hudson would
be making to the combined company, excluding any projected cost savings, and
compared this to the pro forma ownership of the outstanding Dime United stock by
Dime stockholders and Hudson stockholders. Credit Suisse First Boston noted
that, based on the Dime exchange ratio and the number of shares of Dime stock
and Hudson stock outstanding at September 12, 1999, Dime stockholders would own
approximately 55.9% and Hudson stockholders would own approximately 44.1% of the
outstanding Dime United stock upon completion of the merger. Credit Suisse First
Boston compared these percentages to the following pro forma data:

</TABLE>

     Credit Suisse First Boston noted that the exchange ratios reflected the
relative market capitalizations of Dime and Hudson rather than their respective
contributions to the combined company in terms of pro forma earnings and assets,
and that this in turn reflected the disparity between the price/earnings and
book/earnings multiples of the two companies, which is shown in the following
table:

     Merger Consequences Analysis.  Credit Suisse First Boston analyzed the pro
forma effect of the merger on the estimated earnings per share of Dime for 2000
and 2001. In performing this analysis, Credit Suisse First Boston considered the
cost savings expected to be achieved in 2000 and 2001.

     Based on this analysis, Credit Suisse First Boston calculated that the
merger would be 6.8% dilutive to Dime's estimated earnings per share for 2000
given a phase-in of approximately 50% of the anticipated cost savings resulting
from the merger. Credit Suisse First Boston further calculated that the
transaction would be 0.1% accretive to Dime's estimated earnings per share for
2001, when 100% of the anticipated cost savings were assumed to have been
realized.

     Credit Suisse First Boston also calculated the present value of the
projected cost savings anticipated from the merger. These cost savings are
sometimes referred to as synergies in this document. Using discount rates of
11%-15% and assuming a 3% perpetual growth rate, Credit Suisse First Boston
calculated

                                       39
<PAGE>   49

the present value of such cost savings to be between $393 million and $604
million, of which 55.9% would be allocated to Dime stockholders based on the
Dime exchange ratio. Credit Suisse First Boston noted that this 55.9% share
would represent $219-$334 million of cost savings on a present value basis,
equal to approximately 10.6%-16.1%, respectively, of Dime's total market
capitalization on September 10, 1999.

     In addition, Credit Suisse First Boston analyzed the potential impact on
trading values for Dime stockholders if the Dime United stock issued in the
merger were to trade at a multiple closer to the multiple at which Hudson stock
trades or the average trading multiple of Hudson's peer group.

     For purposes of this analysis, Credit Suisse First Boston calculated an
implied price per share of Dime stock by applying different multiples to the pro
forma estimated year 2000 earnings of Dime United. The results of this analysis
are shown in the table below:

     Engagement of Credit Suisse First Boston.  Under the terms of Credit Suisse
First Boston's engagement, Dime has agreed to pay Credit Suisse First Boston a
total fee of $11 million, $2 million of which was payable upon execution of the
merger agreement, $2 million of which was payable upon the mailing of this
document and the remaining $7 million of which will be payable upon the
consummation of the merger. Dime has also agreed to indemnify Credit Suisse
First Boston and various related persons and entities against various
liabilities, including liabilities under the federal securities laws, arising
out of Credit Suisse First Boston's engagement, and to reimburse Credit Suisse
First Boston for its reasonable out-of-pocket expenses, including the reasonable
fees and expenses of its legal counsel, incurred by Credit Suisse First Boston
in connection with its engagement. In the ordinary course of its business,
Credit Suisse First Boston and its affiliates may actively trade the debt and
equity securities of both Hudson and Dime for their own accounts and for the
accounts of customers and, accordingly, may at any time hold a long or short
position in these securities. In the past, Credit Suisse First Boston provided
financial advisory and financial services to Dime and received customary fees
for those services.

OPINION OF HUDSON'S FINANCIAL ADVISOR

     Hudson retained Goldman Sachs to act as its financial advisor in connection
with a possible business combination with Dime based upon Goldman Sach's
qualifications, expertise and reputation, as well as upon its prior investment
banking relationship with Hudson. At a meeting of the Hudson board of directors
held on September 14, 1999, Goldman Sachs made a presentation on financial
aspects of the merger, and Goldman Sachs rendered a written opinion dated
September 14, 1999 that, based upon and subject to the considerations set forth
in its opinion, as of September 14, 1999, the Hudson exchange ratio was fair
from a financial point of view to the holders of Hudson stock. Goldman Sachs
subsequently confirmed its September 14, 1999 opinion by delivering to the
Hudson board of directors a written opinion dated as of the date of this
document. In connection with its subsequent opinion, Goldman Sachs performed
procedures to update certain of its analyses and reviewed the assumptions used
in its analyses and the factors considered in connection with its earlier
opinion. Goldman Sachs has reviewed the disclosure relating to its opinion
contained in this document and has consented to the inclusion of that
disclosure.

     The adjustment to the Dime exchange ratio, as an antidilution adjustment
made pursuant to the terms of the merger agreement, did not affect Goldman
Sachs' analyses because the adjustment did not affect the relative economic
interests of either the Dime or the Hudson stockholders.

     You should consider the following when reading the description of Goldman
Sachs' opinion in this document:

     - The description of Goldman Sachs' opinion is qualified by reference to
       the full opinion attached as Appendix E to this document, which we
       encourage you to read carefully and in its entirety.

     - Goldman Sachs' services and opinion were provided to the Hudson board of
       directors for its information and assistance in its consideration of the
       merger and its opinion is directed only to the fairness of the Hudson
       exchange ratio from a financial point of view to holders of Hudson stock.
       Its opinion does not constitute a recommendation as to how any holder of
       Hudson stock should vote on the merger or any related matter.

     - Goldman Sachs' opinion does not address the merits of Hudson's underlying
       business decision to engage in the merger.

     - Goldman Sachs' opinion does not address the price or range of prices at
       which Hudson stock or Dime stock may trade before the merger or at which
       Dime United stock may trade.

     - Goldman Sachs' opinion was necessarily based upon conditions as they
       existed and could be evaluated on the date of its opinion and this
       document, and Goldman Sachs has assumed no responsibility to update or
       revise its opinion based upon circumstances or events occurring after the
       date of this document.

     In connection with its opinion, Goldman Sachs, among other things:

     - reviewed the merger agreement;

     - reviewed the annual reports to stockholders of Hudson and of Dime for
       each of the years in the five-year period ended December 31, 1998;

     - reviewed the annual reports on Form 10-K of Hudson and of Dime for each
       of the years in the five-year period ended December 31, 1998;

     - reviewed certain interim reports to stockholders and quarterly reports on
       Form 10-Q of Hudson and of Dime;

     - reviewed certain other communications from Hudson and Dime to their
       respective stockholders;

     - reviewed internal financial analyses and forecasts for Hudson and Dime
       prepared by their respective managements for 1999, and reviewed cost
       savings and operating synergies projected by the management of Hudson to
       result from the merger;

     - held discussions with members of the senior management of Hudson and Dime
       regarding the strategic rationale for, and the potential benefits of, the
       merger and the past and current business operations, financial condition
       and future prospects of their respective companies;

     - reviewed the reported prices and trading activity for Hudson stock and
       Dime stock;

     - compared certain financial and stock market information for Hudson and
       Dime with similar information for certain other publicly-traded
       companies;

     - reviewed the financial terms of certain recent business combinations in
       the commercial banking and thrift industries specifically and in other
       industries generally; and

     - performed other studies and analyses as it considered appropriate.

     Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information reviewed by it and assumed that accuracy and
completeness for purposes of rendering its opinion. In that regard, Goldman
Sachs assumed with Hudson's consent that the projected cost savings and
operating synergies expected to result from the merger were reasonably prepared
on a basis reflecting the best estimates and judgments available to Hudson when
such estimates and judgments were made. Goldman Sachs relied at Hudson's request
on the estimates of future performance published by I/B/E/S
                                       41
<PAGE>   51

for periods beyond fiscal 1999, and Goldman Sachs assumed the accuracy and
timing of such forecasts and estimates. In addition, Goldman Sachs assumed that
the merger will be accounted for as a pooling of interests under generally
accepted accounting principles and that all material governmental, regulatory or
other consents and approvals necessary for the consummation of the merger will
be obtained without any adverse effect on Hudson or Dime or on the contemplated
benefits of the merger.

     Goldman Sachs is not an expert in the evaluation of loan and lease
portfolios for the purposes of assessing the adequacy of the allowances for
losses with respect to those portfolios, and Goldman Sachs therefore assumed,
with Hudson's consent, that the existing allowances for each of Hudson and Dime
are in the aggregate adequate to cover all losses with respect to those
portfolios. Goldman Sachs did not review individual credit files or make an
independent evaluation or appraisal of the assets and liabilities, including any
hedge or derivative positions, of Hudson or Dime or any of their respective
subsidiaries and Goldman Sachs was not furnished with any such evaluation or
appraisal.

     Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. Goldman Sachs is
familiar with Hudson, having provided certain financial advice from time to
time, including having provided Hudson a fairness opinion in July 1996 in
connection with the acquisition of Lafayette American Bank and Trust Company and
in June 1999 in connection with the acquisition of JeffBanks, Inc. and having
acted as financial advisor in connection with, and having participated in,
certain of the negotiations leading to the merger agreement. During the two
years prior to the date of this document, Hudson has paid fees to Goldman Sachs
totaling $450,000 for providing financial services other than those relating to
the merger of Dime and Hudson.

     Goldman Sachs also has provided certain investment banking services to Dime
from time to time, including having acted as a co-manager of Dime's public
offering of $150 million aggregate principal amount of 7% Notes due 2001 in July
1999 and as financial advisor in connection with Dime's purchase of the
automobile finance business conducted by Citibank, N.A. effective as of August
1, 1999. Goldman Sachs provides a full range of financial advisory and
securities services, and, in the course of its normal trading activities, may
from time to time effect transactions and hold securities, including derivative
securities, of Hudson and Dime for its own account and for the accounts of
customers.

     Hudson has agreed to pay Goldman Sachs a transaction fee of 0.75% of the
aggregate consideration paid in a sale of 50% or more of the assets of Hudson,
or of the outstanding Hudson stock, including the exchange of the shares of
Hudson stock for shares of Dime stock in the merger, payable in cash upon
completion of the merger. Based on an estimated 52,240,000 fully-diluted shares
of Hudson stock as of January 31, 2000, and the closing price of Dime stock on
that date of $14 1/8, this fee would be approximately $9 million. Hudson has
also agreed to reimburse Goldman Sachs for its reasonable out-of-pocket
expenses, including attorneys' fees, and for any sales, use or similar taxes
arising in connection with its engagement, and to indemnify Goldman Sachs
against certain liabilities, including certain liabilities under the federal
securities laws.

     The following is a summary of the material financial analyses performed by
Goldman Sachs in arriving at its opinion and does not purport to be a complete
description of the analyses performed by Goldman Sachs. Unless otherwise
indicated, the following quantitative information, to the extent it is based on
market data, is based on market data as it existed on or about September 10,
1999, the last trading day prior to the date on which Goldman Sachs made its
presentation on the financial aspects of the merger to the Hudson board of
directors, and is not necessarily indicative of current market conditions. In
addition, all future estimates of earnings and growth rates are based on I/B/E/S
estimates unless otherwise indicated. You should understand that the order of
analyses, and results of those analyses, described below is not intended to
indicate any relative importance given to those analyses by Goldman Sachs. The
summary of financial analyses includes information presented in tabular format,
which should be read together with the text that accompanies those tables.

     Summary of Proposed Transaction.  Goldman Sachs reviewed the proposed terms
of the merger, including the structure, exchange ratios, ownership composition,
board composition and composition of senior management of the combined company.
Goldman Sachs noted that, based upon the Dime and Hudson exchange ratios, Hudson
stockholders would own approximately 44% of Dime United and Dime stockholders
would own approximately 56% of Dime United immediately following the merger.
Goldman Sachs also noted that, pursuant to the merger agreement, Hudson board
members would comprise 48% of Dime United's board, with Dime board members
comprising the remaining 52%. Goldman Sachs further noted that, pursuant to the
merger agreement, the chairman and chief executive officer of Dime would
continue to hold those positions with Dime United and DimeBank through 2002,
while the chairman and chief executive officer of Hudson would serve both Dime
United and DimeBank as president and chief operating officer until that time, at
which point he would succeed to the positions of chairman and chief executive
officer.

     Contribution Analysis.  Goldman Sachs analyzed the relative contributions
of Hudson and Dime to the combined company with respect to market
capitalization, loans, assets, deposits, equity, tangible equity, 1999 estimated
net income and 2000 estimated net income. The following table summarizes this
analysis:

     Goldman Sachs also noted that following the merger, Dime United would rank
within the top 35 U.S. banks and thrifts based on total assets as of June 30,
1999 and within the top 40 U.S. banks and thrifts based on market capitalization
as of September 10, 1999.

     Overview of Dime.  Goldman Sachs conducted a detailed review of Dime's
business and financial results. Goldman Sachs performed an analysis of the
source of Dime's earnings for fiscal 1998, which noted that approximately 24% of
Dime's earnings were from mortgage banking, including originations and
servicing, 48% from retail banking, including consumer financial services and
lending, 20% from commercial banking, including commercial real estate lending
and business banking, and 8% from its investment portfolio. Goldman Sachs
reviewed certain aspects of these segments, including business activities
conducted, geographic market presence and historical performance and growth
rates. For Dime's mortgage banking operations, Goldman Sachs reviewed the
mortgage banking earnings' sensitivity to changes in origination levels and
reviewed the valuation of Dime's mortgage servicing rights under varying
assumptions. Goldman Sachs also reviewed the ownership of Dime stock, noting
that institutional investors held 64.1% of Dime stock and executive officers and
directors of Dime held 1.8% of Dime stock. In addition, Goldman Sachs reviewed
the profiles of the members of Dime's executive management and of the Dime
Board.

     Overview of Hudson and Dime.  Goldman Sachs reviewed and compared certain
aspects of Dime's, Hudson's and Dime United's businesses. Among other things,
Goldman Sachs reviewed and compared

                                       43
<PAGE>   53

deposit market share and deposit composition information for Dime, Hudson and
Dime United. Goldman Sachs also reviewed and compared loan portfolio composition
information for Dime, Hudson, Dime United and certain other banks and thrift
institutions that it deemed relevant to its analysis. In addition, Goldman Sachs
analyzed the contribution of mortgage banking earnings to Dime's and to Dime
United's total earnings. Goldman Sachs also compared the institutional investors
holding shares of Dime stock to the institutional investors holding shares of
Hudson stock.

     Comparison of Selected Public Companies.  Goldman Sachs reviewed and
compared selected financial information, ratios and multiples for Hudson and
Dime to corresponding financial information, ratios and multiples for eight
Northeast regional banking companies (Summit, M&T Bank, North Fork -- pro forma
for the acquisition of JSB Financial Inc. announced August 16, 1999, Valley
National, Keystone Financial, Fulton Financial, Commerce Bancorp and Chittenden
Corporation), four large capitalization banking companies (First Union, Fleet
Financial, PNC and KeyCorp) and eight regional thrifts (Charter One, GreenPoint
Financial, Peoples Heritage, Astoria Financial, Sovereign Bancorp, People's
Bank, Roslyn Bancorp and Webster Financial).

     The selected companies were chosen because they have certain operational
and other characteristics that Goldman Sachs deemed comparable to Hudson and
Dime for purposes of its analysis. Unless otherwise indicated, the multiples and
ratios were calculated using information at or for the 12-month period ended
March 31, 1999. Goldman Sachs' analyses included the following financial
information, ratios and multiples:

     - closing price per share on September 10, 1999 as a percentage of the
       highest stock price for the previous 52-week period;

     - the ratio of the closing price per share on September 10, 1999 to the
       I/B/E/S estimated GAAP earnings per share ("EPS") for calendar years
       1999, 2000 and 2001;

     - estimated 5-year growth rates, provided by I/B/E/S ("5-Year Growth
       Rates");

     - the ratio of the closing price per share on September 10, 1999 to
       estimated 2000 EPS as a multiple of 5-Year Growth Rates;

     - the ratio of the closing price per share on September 10, 1999 to
       estimated 1999 cash earnings per share ("Cash EPS");

     - the ratio of the closing price per share on September 10, 1999 to
       estimated 2000 Cash EPS;

     - the ratio of the closing price per share on September 10, 1999 to
       tangible book value per share;

     - the ratio of tangible common equity to tangible assets;

     - return on average assets for last 12 months; and

     - return on average common equity for last 12 months.

     Historical Stock Price Performance Analysis.  Goldman Sachs reviewed the
closing per share market prices for Dime stock on a daily basis from March 10,
1999 to September 10, 1999, and on a weekly basis from September 10, 1996 to
September 10, 1999. Goldman Sachs compared the stock price performance for Dime,
Hudson, an index of six Northeast regional banks (including M&T Bank, North
Fork, Valley National, Commerce Bancorp, Keystone Financial, Fulton Financial)
and an index of seven regional thrifts (including Charter One, GreenPoint,
Astoria Financial, Sovereign Bancorp, Peoples Bank, Roslyn Bancorp and Webster
Financial) for those periods.

     Goldman Sachs observed that:

     - the closing per share market price for Dime stock on a daily basis from
       March 10, 1999 to September 10, 1999 declined by 33%,

     - the closing per share market price for Hudson stock over that period
       declined by 7%,

     - the closing per share market price for the Northeast regional bank index
       over that period declined by 10%, and

     - the closing per share market price for the regional thrift index over
       that period declined by 17%.

     In addition, Goldman Sachs observed that:

     - the closing per share market price for Dime stock on a weekly basis from
       September 10, 1996 to September 10, 1999 increased by 43%,

     - the closing per share market price for Hudson stock over that period
       increased by 66%,

     - the closing per share market price for the Northeast regional bank index
       over that period increased by 55%, and

     - the closing per share market price for the regional thrift index over
       that period increased by 44%

     Historical Forward Price to Earnings Trading Analysis.  Goldman Sachs
reviewed the ratio of the closing per share market prices for Dime stock on a
daily basis from March 10, 1999 to September 10, 1999, and on a weekly basis
from September 10, 1996 to September 10, 1999, to Dime's projected EPS. This
analysis showed that from March 10, 1999 to September 10, 1999, Dime's price to
one year forward fiscal earnings declined from 12.9x to 8.4x, and from September
10, 1996 to September 10, 1999 Dime's price to one year forward fiscal earnings
declined from 12.0x to 8.4x.

     Accretion/Dilution Analysis.  Goldman Sachs analyzed the pro forma impact
of the merger on Dime's estimated 2000 EPS and estimated 2001 EPS. Based on
management assumptions with respect to the size and timing of cost savings and
other assumptions regarding goodwill amortization periods, the size of the
restructuring reserve, interest and tax rates and the use of
pooling-of-interests accounting, none of which was independently verified by
Goldman Sachs, Goldman Sachs' analysis of the merger from Hudson's perspective
showed that the merger, compared to continued operation of Hudson on a stand-
alone basis, would be 32% accretive to estimated 2000 EPS and 40% accretive to
estimated 2001 EPS.

     Historical Exchange Ratio Analysis.  Goldman Sachs calculated the ratio of
the closing price per share of Dime stock to the closing price per share of
Hudson stock for each trading day in the period from September 10, 1996 to
September 10, 1999. Goldman Sachs compared the Dime exchange ratio of 0.585-to-1
to the results of this analysis, which showed an implied exchange ratio of
0.7610-to-1 based on the three-year daily average per share closing market
prices of Dime stock and Hudson stock, an implied exchange ratio of 0.7616-to-1
based on the one-year daily average per share closing market prices of Dime
stock and Hudson stock, an implied exchange ratio of 0.6291-to-1 based on the
three-month daily average per share closing market prices of Dime stock and
Hudson stock and an implied exchange ratio of 0.5754-to-1 based on the closing
prices per share of Dime Stock and Hudson stock on September 10, 1999. The
antidilution adjustment to the Dime exchange ratio did not affect the substance
of this analysis because the historical exchange ratios against which the Dime
exchange ratio was compared would have been proportionately adjusted if the
antidilution adjustment had been made prior to the completion of the analysis.

     Comparable Transactions Analysis.  Goldman Sachs analyzed certain terms,
the consideration paid and other information in the following merger-of-equals
transactions, which it deemed relevant to its analysis (acquiror/target):
Fleet/Bank Boston, UNUM/Provident, Norwest/Wells Fargo, NationsBank/
BankAmerica, Banc One/First Chicago NBD, Travelers/Citicorp, Chemical/Chase,
First Chicago/NBD. The following table compares information derived by Goldman
Sachs with respect to the these selected transactions:

Goldman Sachs also reviewed certain other aspects of the foregoing
mergers-of-equals transactions, including chairman/chief executive officer
arrangements, headquarters and name.

     The preparation of a fairness opinion is a complex process involving
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, is not necessarily susceptible to partial analysis
or summary description. Selecting portions of the analyses or of the summary set
forth above, without considering the analyses as a whole, could create an
incomplete view of the processes underlying Goldman Sachs' opinion. In arriving
at its fairness determination, Goldman Sachs considered the results of all of
its analyses and did not attribute any particular weight to any factor or
analysis considered by it; rather, Goldman Sachs made its determination as to
fairness on the basis of its experience and professional judgment after
considering the results of all these analyses. In addition, in performing its
analyses, Goldman Sachs made numerous assumptions with respect to industry
performance, general business, economic, market and

                                       46
<PAGE>   56

financial conditions and other matters. No company or transaction used in the
above analyses as a comparison is directly comparable to Hudson or Dime or the
merger. The analyses were prepared for purposes of Goldman Sachs providing its
opinion to the Hudson board of directors as to the fairness of the Hudson
exchange ratio from a financial point of view and do not purport to be
appraisals or necessarily reflect the prices at which businesses or securities
actually may be sold. Analyses based upon forecasts of future results are not
necessarily indicative of actual future results, which may be significantly more
or less favorable than suggested by those analyses. Because those analyses are
inherently subject to uncertainty, being based upon numerous factors or events
beyond the control of the parties or their respective advisors, Goldman Sachs
does not assume responsibility if future results are materially different from
those forecast.

     As described above, the opinion of Goldman Sachs to the Hudson board of
directors was among many factors taken into consideration by the Hudson board of
directors in making its determination to approve the merger agreement.
Consequently, the analyses described above should not be viewed as determinative
of the Hudson board of directors' or Hudson management's opinion with respect to
the value of Hudson or a combination of Hudson and Dime, or of whether the
Hudson board of directors or Hudson management would have been willing to agree
to a different Hudson exchange ratio. Hudson placed no limits on the scope of
the analysis performed, or opinion expressed, by Goldman Sachs.

BOARD AND MANAGEMENT OF DIME UNITED AND DIMEBANK

     Boards of Directors.  The merger agreement provides that the board of
directors of each of Dime United and DimeBank will consist of a total of 25
directors. Thirteen of these directors will be designated by Dime prior to
completion of the merger; twelve of these directors will be designated by Hudson
prior to completion of the merger. These directors will be split as evenly as
possible among the three classes of directors on the classified board of Dime
United. Both Mr. Toal and Mr. Neilson will be members of the boards of
directors. We each will designate our respective number of directors for the
boards prior to completion of the merger and the bank merger, and Dime and
Hudson United Bank will adopt resolutions to have such persons placed on the
Dime United and DimeBank boards of directors, respectively, as of the completion
of the merger and the bank merger. No determination has yet been made as to who
will be on the Dime United and DimeBank boards of directors, but the directors
are expected to be selected from Dime's and Hudson's existing boards of
directors.

     We have also agreed to create committees of the Dime United and DimeBank
boards of directors and have agreed to the composition of these committees.
These committees are described in Annex 3 to the merger agreement included as
Appendix A to this document. We each will designate appropriate directors to be
members of these committees, and Dime and Hudson United Bank will adopt
resolutions to establish the committees and to have the designated directors
placed on the committees.

     Management.  The merger agreement provides that Mr. Toal will serve as
Chairman of the Board and Chief Executive Officer of both Dime United and
DimeBank, and Mr. Neilson will serve as President and Chief Operating Officer of
both Dime United and DimeBank, until December 31, 2002. The merger agreement
also provides that, on December 31, 2002, or such earlier date that Mr. Toal
shall cease to be Chairman and Chief Executive Officer, Mr. Neilson will succeed
Mr. Toal as Chairman of the Board and Chief Executive Officer, unless a Special
Majority, as discussed in "Corporate Governance after the Merger" on pages
49-50, of the Dime United board of directors decides otherwise. See "Interests
of Management and Directors in the Merger -- New Employment Arrangements" on
pages 56-58 for further information regarding the employment arrangements for
Mr. Toal and Mr. Neilson. In addition, as set

                                       47

forth in Annex 5 to the merger agreement included as Appendix A to this

     Remaining staff positions with Dime United or DimeBank have not yet been
fully determined. From time to time prior to consummation of the merger,
decisions may be made with respect to the management of Dime United and
DimeBank.

     Corporate Governance After the Merger.  The merger agreement contains
certain provisions regarding the governance of Dime United for the period from
the completion of the merger until December 31, 2002. These provisions include
the following:

     - A person may be qualified for election as a director at an annual or
       special meeting of the stockholders, or by unanimous written consent of
       stockholders, of Dime United if the person is

       - nominated by a stockholder in accordance with the stockholder
         nomination procedures of Dime United's certificate of incorporation and
         by-laws, or

       - nominated by the board of directors after the person has been nominated
         to the board of directors by the nominating committee procedures
         discussed below.

     - A person may be qualified for election as a director by the board of
       directors when filling a vacancy or a newly created directorship by first
       having been nominated to the board of directors by the nominating
       committee procedures discussed below.

     - The nominating committee procedures consist of nomination by a
       three-member nominating committee.

       - For directorships occupied by, vacated by, to be occupied by or
         designated for a former Dime director, the nominating committee will
         consist of two former Dime directors and one former Hudson director.
         For directorships occupied by, vacated by, to be occupied by or
         designated for a former Hudson director, the nominating committee will
         consist of two former Hudson directors and one former Dime director.

       - Former Dime directors on any nominating committee will be appointed
         from time to time by the board at the recommendation of Mr. Toal, or
         the most senior former Dime director on the Dime United board of
         directors if Mr. Toal cannot make the recommendation. Former Hudson
         directors on any nominating committee will be appointed from time to
         time by the board at the recommendation of Mr. Neilson, or the most
         senior former Hudson director on the Dime United board of directors if
         Mr. Neilson cannot make the recommendation.

       - A nominating committee may only act by a vote of at least two of the
         three members of the nominating committee.

     - A person elected and qualified under these nominating committee
       procedures will be designated as a former Dime director or a former
       Hudson director, as appropriate.

     - All former Dime directors and all former Hudson directors are also
       considered continuing directors for purposes of determining a special
       majority on the Dime United board of directors, as described below.

     - A special majority of the Dime United board of directors will consist of
       the affirmative vote of a majority of the members of the board voting,
       but will also require the vote of a number of continuing directors equal
       to the number of former Dime directors in office plus three or, if there
       are less than three former Hudson directors in office, then plus that
       number of former Hudson directors.

                                       49
<PAGE>   59

     - A special majority of the Dime United board of directors will be required
       for:

       - Altering provisions for the succession of Mr. Neilson to the positions
         of Chairman of the Board and Chief Executive Officer, as described in
         "Board and Management of Dime United and DimeBank" on pages 47-50;

       - The removal of Mr. Toal or Mr. Neilson from their positions as officers
         of the company, as each position is filled at the completion of the
         merger; and

       - Any material change to or breach of either Mr. Toal's or Mr. Neilson's
         employment agreement.

     - If the board of directors decides to increase or decrease the number of
       directors, the board of directors will designate the vacancies or will
       otherwise use their best efforts to keep the ratio of former Dime
       directors to former Hudson directors as close to equal as possible to the
       ratio that will exist on the date of completion of the merger.

     - If both a nominating committee for a former Dime director position and a
       nominating committee for a former Hudson director position so recommend,
       the Dime United board of directors may decide:

       - not to allocate directorships so as to keep the ratio the same as on
         the date of the completion of the merger in the manner described in the
         preceding paragraph, or

       - not to apply the nominating committee procedures to any one or more
         directorships.

     Amendments to Dime Certificate of Incorporation and By-Laws.  These
corporate governance procedures and the provisions related to the size of the
board and the management of Dime United discussed above will be put into place
by amendments to the certificate of incorporation of Dime effected by the merger
pursuant to the provisions of the merger agreement or by amendments to the
by-laws of Dime effected by the Dime board of directors, each of which will
become effective at the completion of the merger. These procedures are scheduled
to be in place only until December 31, 2002. The amendments to the certificate
of incorporation and to the by-laws of Dime are described more fully in Annex 1
and Annex 2, respectively, to the merger agreement which is included as Appendix
A to this document. In addition, the amendments to the certificate of
incorporation will change the name of Dime to Dime United Bancorp, Inc. Adoption
or approval of the merger agreement will also result in adoption of the
amendments to the Dime certificate of incorporation.

DISTRIBUTION OF DIME UNITED CERTIFICATES

     Hudson stockholders are not required to exchange their Hudson stock
certificates for certificates of Dime United, unless we determine that such
exchange is legally required, in which case we will give you instructions on how
to exchange your Hudson stock certificates for Dime United stock certificates.

     At or prior to the completion of the merger, Dime will cause to be
deposited with an exchange agent for the benefit of the holders of certificates
representing shares of Dime stock, certificates representing shares of Dime
United stock.

     Promptly after the completion of the merger, Dime United will send or cause
to be sent transmittal materials to each holder of a Dime stock certificate for
use in exchanging Dime stock certificates for certificates representing shares
of Dime United stock. HOLDERS OF DIME STOCK CERTIFICATES SHOULD NOT SURRENDER
THEIR DIME STOCK CERTIFICATES FOR EXCHANGE UNTIL THEY RECEIVE THE LETTER OF
TRANSMITTAL AND INSTRUCTIONS. The exchange agent will deliver certificates for
Dime United stock and/or a check instead of any fractional shares of Dime United
Stock once it receives the certificates representing a holder's shares of Dime
stock.

     Holders of Dime stock certificates may exchange those certificates for Dime
United stock certificates with the exchange agent for up to one year after the
completion of the merger. At the end of that period, any Dime United stock
certificates and cash will be returned to Dime United. Any holders of Dime stock
certificates who have not exchanged their certificates will be entitled to look
only to Dime United, and

                                       50
<PAGE>   60

only as general creditors of Dime United, for Dime United stock certificates and
any cash to be received instead of fractional shares of Dime United stock.

     No interest will be paid or will accrue on any amount payable upon
surrender of Dime stock certificates. If any Dime United stock certificate or
cash payment instead of a fractional share of Dime United stock is to be issued
or made in a name other than that in which the Dime stock certificate
surrendered is registered, the person requesting the exchange must pay any
transfer or other taxes required by reason of the issuance of the Dime United
stock certificate or cash payment instead of a fractional share of Dime United
stock or must establish to the satisfaction of Dime United that any taxes have
been paid or are not applicable.

     Any person claiming that a Dime stock certificate has been lost, stolen or
destroyed may receive a Dime United stock certificate upon the making of an
affidavit of that fact, and Dime United will issue Dime United stock
certificates to the claimant and pay any applicable amounts of cash instead of
fractional shares of Dime United stock. Dime United may require the claimant to
post a bond in a reasonable amount as an indemnity against any claim that may be
made against Dime United with respect to the lost, stolen or destroyed Dime
stock certificate.

     At or after the completion of the merger, there will be no transfers on the
stock transfer books of Hudson of the shares of Hudson stock that were
outstanding immediately prior to that time.

FRACTIONAL SHARES

     Dime United will not issue any fractional shares of Dime United stock.
Instead, a Dime stockholder who would otherwise have received a fraction of a
share of Dime United stock pursuant to the Dime exchange ratio will receive cash
without interest instead of a fractional share. The amount of cash received will
be determined by multiplying the fraction of a share of Dime United stock to
which such holder would otherwise be entitled by the average of the closing
price per share of Hudson stock for the ten trading days most recently preceding
the closing date of the merger as reported on the NYSE Composite Transactions
reporting system. Fractional shares of Dime United stock will, however, be
issued into a dividend reinvestment plan, 401(k) plan or other similar stock
plan of Dime United at the completion of the merger.

FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

     The following is a summary of the material federal income tax consequences
to holders of Dime stock or Hudson stock who hold such stock as a capital asset
within the meaning of Section 1221 of the Internal Revenue Code of 1986. Special
tax consequences may be applicable to particular classes of taxpayers, such as
financial institutions, insurance companies, tax-exempt organizations,
broker-dealers, traders in securities that elect to apply a mark-to-market
method of accounting, persons that hold Dime stock or Hudson stock as part of a
hedge, straddle or conversion transaction, persons who are not citizens or
residents of the United States and stockholders who acquired their shares of
Dime stock or Hudson stock through the exercise of an employee stock option or
otherwise as compensation. The following discussion is based upon the Internal
Revenue Code, its legislative history, existing and proposed regulations
thereunder, published rulings and decisions, all as currently in effect as of
the date hereof, and all of which are subject to change, possibly with
retroactive effect. Tax considerations under state, local and foreign laws are
not addressed in this document. The tax treatment discussed below may not apply
to certain Dime or Hudson stockholders. Determining the actual tax consequences
of the merger to you may be complex. They will depend on your specific situation
and on factors not within our control. YOU SHOULD CONSULT WITH YOUR OWN TAX
ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES OF THE MERGER TO YOU, INCLUDING
THE APPLICABILITY AND EFFECT OF THE ALTERNATIVE MINIMUM TAX AND ANY STATE, LOCAL
OR FOREIGN INCOME AND OTHER TAX LAWS AND OF CHANGES IN THOSE TAX LAWS.

                                       51

     Tax Consequences of the Merger Generally.

     The following disclosure summarizes the opinions of Sullivan & Cromwell,
counsel to Dime, and Pitney, Hardin, Kipp & Szuch, LLP, counsel to Hudson,
received by each of Dime and Hudson. Assuming the merger is completed in the
manner described in this document, for federal income tax purposes, and as
described in these opinions.

     - the merger will be treated as a reorganization within the meaning of
       Section 368(a) of the Internal Revenue Code,

     - no income, gain or loss will be recognized by Dime or Hudson pursuant to
       the merger, and

     - a stockholder of Dime or Hudson who receives solely Dime United stock in
       exchange for its shares of Hudson stock or Dime stock in the merger will
       not recognize any income, gain or loss, except, as discussed below, with
       respect to cash received by a stockholder of Dime instead of fractional
       shares of Dime United stock.

     These opinions have been filed as exhibits to the registration statement
that registers the Dime United stock to be issued in this merger. These opinions
are based in part on assumptions set forth in such opinions and facts (but not
legal conclusions) specified in letters of representation received by counsel
from each of Dime and Hudson.

     In addition to the opinions already received, it is a condition to the
completion of the merger that:

     - Dime receive an opinion of Sullivan & Cromwell, dated the closing date of
       the merger, to the effect that, on the basis of facts, factual
       representations and assumptions set forth in that opinion, the merger
       will be treated as a tax-free reorganization within the meaning of
       Section 368(a) of the Internal Revenue Code and that Dime and Hudson will
       each be a party to the reorganization under Section 368(b) of the
       Internal Revenue Code; and

     - Hudson receive an opinion of Pitney, Hardin, Kipp & Szuch LLP, dated the
       closing date of the merger, to the effect that, on the basis of facts,
       factual representations and assumptions set forth in that opinion, (1)
       the merger will be treated as a tax-free reorganization within the
       meaning of Section 368(a) of the Internal Revenue Code, (2) Dime and
       Hudson will each be a party to the reorganization under Section 368(b) of
       the Internal Revenue Code, and (3) subject to customary exceptions, no
       income, gain or loss will be recognized by Dime, Hudson or Hudson
       stockholders in connection with the merger.

Although the merger agreement allows us to waive this condition, we currently do
not anticipate doing so. If either of us does waive this condition, we will
inform you of this fact and ask you to vote on the merger taking this into
consideration. Neither of the tax opinions will be binding on the Internal
Revenue Service, but neither Dime nor Hudson intends to request any ruling from
the IRS as to the federal income tax consequences of the merger.

     Exchange of Dime Stock or Hudson Stock Solely for Dime United Stock.  A
Dime stockholder or Hudson stockholder who receives solely Dime United stock in
exchange for his or her shares of Dime stock or Hudson stock in the merger
generally will not recognize any gain or loss upon the exchange. A stockholder
of Dime may recognize gain or loss, however, with respect to cash received
instead of a fractional share of Dime United stock, as discussed below. The
aggregate adjusted tax basis of the shares of Dime United stock received in the
exchange, including fractional shares deemed received and redeemed as described
below, will be equal to the aggregate adjusted tax basis of the shares of Dime
stock or Hudson stock surrendered, and the holding period of the Dime United
stock, including fractional shares deemed received and redeemed as described
below, will include the holding period of such surrendered shares.

     Cash Received Instead of a Fractional Share of Dime United Stock.  A
stockholder of Dime who receives cash instead of a fractional share of Dime
United stock will be treated as having received the fractional share pursuant to
the merger and then as having exchanged the fractional share for cash in a

                                       52
<PAGE>   62

redemption by Dime United subject to Section 302 of the Internal Revenue Code.
That deemed redemption will be treated as a sale of the fractional share, unless
it is both essentially equivalent to a dividend and is not substantially
disproportionate with respect to the Dime stockholder. If treated as a sale and
not a dividend, the Dime stockholder will recognize capital gain or loss equal
to the difference between the amount of cash received and the portion of the
basis of the shares of Dime stock allocable to the fractional interest. This
capital gain or loss will be long-term capital gain or loss if, as of the date
of the exchange, the holding period for the shares of Dime stock is greater than
one year.

     Backup Withholding and Information Reporting.  Payments of cash to a person
surrendering shares of Dime stock will be subject to information reporting and
backup withholding at a rate of 31% of the cash payable, unless such person
furnishes its taxpayer identification number in the manner prescribed in
applicable Treasury regulations, certifies that the number is correct, certifies
as to no loss of exemption from backup withholding and meets certain other
conditions. Any amounts withheld from payments under the backup withholding
rules will be allowed as a refund or credit against federal income tax
liability, provided the required information is furnished to the IRS.

ACCOUNTING TREATMENT

     We intend for the merger to be accounted for as a pooling of interests, as
that term is used under GAAP, for accounting and financial reporting purposes
and have agreed not to take any action that would adversely affect the
qualification of the merger for this treatment. Under the pooling-of-interests
method of accounting, Dime's consolidated financial statements for prior periods
will be restated to include the assets, liabilities, stockholders' equity and
results of operations of Hudson as if Hudson had always been combined with Dime.
Completion of the merger is conditioned on receipt by Dime and Hudson of letters
from their respective independent public accounting firms to the effect that the
merger will qualify as a pooling of interests for accounting and financial
reporting purposes.

RESALES OF DIME UNITED STOCK BY AFFILIATES

     Affiliates of Dime or Hudson under Rule 145 under the Securities Act or
affiliates of Dime United generally may not sell their shares of Dime United
stock acquired in the merger except pursuant to an effective registration
statement under the Securities Act or an applicable exemption from the
registration requirements of the Securities Act, including Rules 144 and 145
issued by the SEC under the Securities Act. Affiliates include directors,
executive officers, and beneficial owners of 10% or more of any class of capital
stock.

     Dime and Hudson have agreed to use their reasonable best efforts to cause
each person who may be deemed to be an affiliate of Dime or Hudson to execute an
agreement in which that person agrees, among other things, not to offer to sell,
transfer or otherwise dispose of any of the shares of Dime United stock
distributed to him or her pursuant to the merger except in compliance with Rules
144 and Rule 145 under the Securities Act, in a transaction that, in the opinion
of counsel reasonably satisfactory to Dime United, is otherwise exempt from the
registration requirements of the Securities Act, or in an offering registered
under the Securities Act. Dime United may place restrictive legends on
certificates representing its stock issued to all persons who are deemed to be
affiliates of Dime, Hudson or Dime United under the Securities Act. These
agreements also aid Dime and Hudson in complying with accounting rules governing
pooling-of-interests transactions. The forms of these agreements are included as
Annexes 4(a) and 4(b) to the merger agreement, which is attached as Appendix A.

     This document does not cover any resales of Dime United stock received in
the merger by any person who may be deemed an affiliate of Dime, Hudson, or Dime
United.

REGULATORY APPROVALS REQUIRED FOR THE MERGER

     We have agreed to use our reasonable efforts to obtain all regulatory
approvals required to consummate the transactions contemplated by the merger
agreement, which include approval from the Federal Reserve Board and various
state and other regulatory authorities. We have completed the filing of
                                       53
<PAGE>   63

these applications and notifications but have not yet received final regulatory
approval nor have any required notification periods expired. The merger cannot
proceed in the absence of these regulatory approvals. There can be no assurance
that these regulatory approvals will be obtained, and if obtained, there can be
no assurance as to the date of any such approvals or the absence of any
litigation challenging such approvals. There can likewise be no assurance that
the United States Department of Justice or any state attorney general will not
attempt to challenge the merger on antitrust grounds, and if such a challenge is
made, there can be no assurance as to its result.

     We are not aware of any material governmental approvals or actions that are
required for completion of the merger other than those described below. It is
presently contemplated that if any such additional governmental approvals or
actions are required, such approvals or actions will be sought. There can be no
assurance, however, that any such additional approvals or actions will be
obtained.

     Federal Reserve Board.  Because Dime will become a bank holding company
after the merger due to its acquisition of Hudson's commercial bank subsidiary,
Hudson United Bank, the merger is subject to approval by the Federal Reserve
Board under the Bank Holding Company Act of 1956. The merger may not be
consummated until 30 days after the Federal Reserve Board approval, during which
time the Justice Department may challenge the merger on antitrust grounds. The
Federal Reserve Board and the Justice Department may reduce the waiting period
to no less than 15 days.

     The Federal Reserve Board is prohibited under applicable statutes from
approving any transaction that would result in a monopoly, or that would be in
furtherance of any combination or conspiracy to monopolize or to attempt to
monopolize the business of banking in any part of the United States, or that may
have the effect in any section of the United States of substantially reducing
competition, or tending to create a monopoly, or resulting in a restraint of
trade, unless the Federal Reserve Board finds that the anti-competitive effects
of the transaction are clearly outweighed in the public interest by the probable
effect of the transaction in meeting the convenience and needs of the
communities to be served.

     In addition, the Federal Reserve Board will consider the financial and
managerial resources of the companies and their subsidiary depository
institutions. It will also consider the convenience and needs of the communities
to be served by the resulting company and its subsidiary depository
institutions. As part of its consideration of these factors, we expect that the
Federal Reserve Board will consider our respective regulatory status, the
progress each of us has made in achieving resolution of Year 2000 computer
problems and the overall capital and safety and soundness standards established
by and under the Federal Deposit Insurance Corporation Improvement Act of 1991.

     Under the Community Reinvestment Act of 1977, the Federal Reserve Board
will take into account the performance record of each of us, and our respective
depository institution subsidiaries, in meeting the credit needs of the entire
community, including low- and moderate-income neighborhoods, served by each
company. Both Dime Savings Bank and Hudson United Bank have sponsored a variety
of programs and services designed to meet the credit needs of the
low-to-moderate income persons and communities they serve. Hudson United Bank
has received a satisfactory Community Reinvestment Act rating from its federal
regulator at its most recent examination, and Dime Savings Bank has received an
outstanding Community Reinvestment Act rating from its federal regulator in its
last four examinations.

     The Federal Reserve Board will furnish notice and a copy of the application
for approval of the merger to the appropriate state regulatory authorities.
These agencies have 30 days to submit their views and recommendations to the
Federal Reserve Board. The Federal Reserve Board must hold a public hearing if
it receives a written recommendation of disapproval of the application from any
of these agencies within the 30-day period. In addition, the Federal Reserve
Board will take into account compliance with certain state laws regarding
interstate acquisitions of banks. Furthermore, the Bank Holding Company Act and
Federal Reserve Board regulations require publication of notice of, and the
opportunity for public comment on, the application submitted by Dime for
approval of the merger and authorize the Federal Reserve Board to hold a public
hearing or meeting in connection therewith if the Federal Reserve Board
determines that it would be appropriate. Any hearing, meeting or comments from
third parties could prolong the review of the application.
                                       54
<PAGE>   64

     If the Justice Department were to commence an antitrust action, it would
stay the effectiveness of Federal Reserve Board approval of the merger unless a
court specifically orders otherwise. In reviewing the merger, the Justice
Department could analyze the merger's effect on competition differently from the
Federal Reserve Board. It is possible that the Justice Department could reach a
different conclusion from the Federal Reserve Board regarding the merger's
competitive effects. In particular, the Justice Department may focus on the
impact of the merger on competition for loans and other financial services to
small- and middle-market businesses. Failure of the Justice Department to object
to the merger may not prevent private persons or state attorneys general from
filing antitrust actions.

     Federal Deposit Insurance Corporation.  As the primary federal regulator of
Hudson United Bank, the FDIC is required under the Bank Merger Act to approve
the merger of Dime Savings Bank into Hudson United Bank. Although the approval
of the bank merger by the FDIC is not required to complete the merger of Dime
and Hudson, both Dime and Hudson desire to obtain the necessary approvals for
the bank merger as soon as possible so that the subsidiary banks may be merged
simultaneously with the merger of Dime and Hudson.

     When reviewing the application for approval of the merger of Dime Savings
Bank and Hudson United Bank, the FDIC will consider issues with respect to those
institutions that are similar to those considered by the Federal Reserve Board
in its review of the merger of Dime and Hudson under the Bank Holding Company
Act, including, among others, the financial and managerial resources of the
combined bank, effects on competition in the markets served by the two banks,
the convenience and needs of the communities to be served by the resulting bank,
the overall capital and safety and soundness of the resulting bank, and the
records of the two institutions under the Community Reinvestment Act. In
addition, the FDIC will consider the operation of the interstate branches of
DimeBank.

     The discussions above regarding the requirement of the Federal Reserve
Board to request the views and recommendations of the other appropriate
regulatory authorities, the publication of notice to the public regarding the
application and the waiting period for review of the Justice Department are
equally applicable to the application reviewed by the FDIC for the bank merger.

     Other Regulatory Authorities.  Notice was also required to be given to the
Office of Thrift Supervision as the primary federal regulator for Dime Savings
Bank. Applications or notifications have been filed with various state
regulators, including the New Jersey Department of Banking and Insurance as the
primary state regulator of Hudson United Bank. These applications or
notifications are required to be made because the merger or the merger of the
banking subsidiaries may be considered to cause acquisitions, changes in control
or other changes in status or operation of subsidiaries of Dime or Hudson doing
business in these states. In addition, the merger may be reviewed by the
attorneys general in the states where the subsidiaries of Dime and Hudson have
operations. Such authorities may be empowered under applicable state laws and
regulations to investigate and/or disapprove the merger under the circumstances
and based upon the review set forth in those laws and regulations.

INTERESTS OF MANAGEMENT AND DIRECTORS IN THE MERGER

     GENERAL

     Some members of the management of Dime and the management of Hudson, and
some members of the Dime board of directors and the Hudson board of directors,
are stockholders of Dime or stockholders of Hudson. In addition, our directors
and officers have interests in the merger as individuals in addition to, or
different from, their interests as stockholders, as described in this section.

     In addition to the interests discussed in this section of this document,
certain members of management or the boards of directors of Dime and Hudson will
be members of management or the boards of directors of Dime United and DimeBank
and will receive compensation for such services. See "Board and Management of
Dime United and DimeBank" on pages 47-50. Dime and Hudson may also provide
incentives to key employees to ensure that they remain throughout the merger
integration process.

     The Dime board of directors and the Hudson board of directors were both
aware of these interests and considered them in their respective decisions to
approve the merger agreement.

     NEW EMPLOYMENT ARRANGEMENTS

     Agreement with Mr. Toal.  Mr. Toal's existing employment agreement, dated
as of January 30, 1998, with Dime Savings Bank was amended effective October 22,
1999. Dime is jointly and severally liable for the obligations of Dime Savings
Bank under Mr. Toal's agreement. Following the completion of the merger, Mr.
Toal's agreement will continue as an obligation of Dime United and DimeBank. The
terms of Mr. Toal's amended agreement after the merger are as follows:

     The term of Mr. Toal's agreement extends to December 31, 2002 and provides
that he will serve, throughout the term, as Chairman of the Board and Chief
Executive Officer of each of Dime United and DimeBank. Under his agreement, Mr.
Toal's current base salary of $900,000 may be increased, but not decreased, by
the board of directors. Mr. Toal also will continue to be eligible to
participate in an annual cash bonus program with a target bonus opportunity of
at least 50% his base salary, and a long-term incentive program and will
continue to be provided with certain perquisites, such as financial planning
benefits, club memberships and a car and driver. Mr. Toal's agreement also
provides that, immediately following the completion of the merger, he will
receive options to purchase 150,000 shares of Dime United stock at the closing
price on the first trading day following completion of the merger, and, provided
he continues to serve as Chairman of the Board and Chief Executive Officer,
one-third of these options will vest on each of the first and second
anniversaries of the grant and the remaining third will vest on December 30,
2002. Based on a 56% Dime/44% Hudson weighted average of volatility and an
assumed January 31, 2000 grant date, the Black Scholes value of these options
would be $1,595,344.

     Mr. Toal will continue to participate in Dime's current Supplemental
Executive Retirement Plan -- also known as a SERP -- which will be assumed by
Dime United. The SERP provides for a benefit, offset by other defined benefit
plan benefits, generally equal to a stated percentage of average salary and
bonus, payable in the form of a single life annuity at age 65, with actuarially
reduced benefits available commencing at earlier ages. This benefit generally
requires ten years of service to fully vest, except that it will be fully vested
in the event of an involuntary termination without cause, or a termination after
either a reduction in salary or a material reduction in duties, within a
prescribed period after the signing of the merger agreement or the completion of
the merger. Mr. Toal's agreement provides that his SERP pension goal will be not
less than 60%. As of December 31, 1999, Mr. Toal had a pension goal under the
SERP of 60% of his average salary and bonus and had accrued a SERP benefit,
commencing at age 65 in the form of a single life annuity, before offset, of
approximately $1,070,000. Mr. Toal was then 80% vested in that benefit. However,
pursuant to his agreement, Mr. Toal will be fully vested in his SERP benefit in
the event of a termination of his employment other than for cause that otherwise
would trigger a right to change in control-related benefits, as described below.
In addition, when applying the average compensation definition under the SERP
following a change in control, average compensation will, if it results in a
greater benefit, be determined as if Mr. Toal had continued service throughout
the term of his agreement and earned an assumed annual bonus based upon a
formula set forth in the agreement. Furthermore, under his agreement, if, at or
after age 65, his SERP benefit, including other deferred benefit plan benefits,
does not equal at least $1,235,000, he will be entitled, upon retirement, to an
additional payment such that his total retirement benefit, expressed as a single
life annuity, at or after age 65 will not be less than that amount.

     Mr. Toal's agreement also provides for specific benefits following a change
in control, as defined in his agreement. For these purposes, completion of the
merger constitutes such a change in control. Accordingly, if Mr. Toal's
employment is involuntarily terminated other than for cause during the term of
his agreement, or if Mr. Toal terminates his employment during the term after he
has not been re-elected as Chairman or Chief Executive Officer or after there
has been a material diminution in his responsibilities, Mr. Toal will be
entitled to benefits, including a lump sum equal to three times the sum of his
annual salary plus an assumed annual bonus based upon a formula set forth in his
agreement and continued disability, medical, and dental insurance coverage for
Mr. Toal and his spouse for the remainder of their lives. In addition, if any of
these benefits, or any of his SERP-related benefits, results in additional tax
under Section 4999 of the Internal Revenue Code because the amounts are deemed
to constitute parachute payments within the meaning of Section 280G of the
Internal Revenue Code, Dime will make
                                       56
<PAGE>   66

an additional payment so as to provide Mr. Toal with the benefits he would have
received in the absence of such a tax.

     Under Mr. Toal's agreement, his vested stock options will continue to be
exercisable for their full terms notwithstanding any termination of his
employment, and any new stock options granted to him will provide that, once
vested, their terms may not be shortened as a result of termination of his
employment, other than for cause, or otherwise.

     Agreement with Mr. Neilson.  Concurrently with the execution of the merger
agreement, Hudson and Hudson United Bank entered into a new employment agreement
with Mr. Neilson, which primarily contains substantive changes to Mr. Neilson's
employment arrangement that take effect after completion of the merger. The term
of Mr. Neilson's agreement extends to December 31, 2004. Following the
completion of the merger, by operation of law, Dime United and DimeBank will
assume the obligations of Hudson and Hudson United Bank under Mr. Neilson's
employment agreement, and Mr. Neilson will serve as President and Chief
Operating Officer of each of Dime United and DimeBank. Mr. Neilson's employment
agreement also provides that he will succeed Mr. Toal on December 31, 2002, or
earlier if Mr. Toal leaves office earlier, as Chairman of the Board and Chief
Executive Officer of those entities. The terms of Mr. Neilson's employment after
the merger are as follows:

     Mr. Neilson's base salary will initially be at least $750,000, or, if
greater, 80% of Mr. Toal's salary, and at least $1,000,000 once he becomes
Chairman of the Board and Chief Executive Officer of both Dime United and
DimeBank. Also, he will be eligible to participate in Dime United's cash
incentive plan, with an annual target bonus opportunity of at least 100% of his
base salary, and to receive annual stock incentive awards while he is President
and Chief Operating Officer equal to 80% of Mr. Toal's base annual stock
incentive awards. Mr. Neilson will be provided with a car and driver while based
in New York City, financial planning benefits and club memberships. After Mr.
Neilson becomes Chairman of the Board and Chief Executive Officer, he will be
eligible to receive annual stock incentive awards on a basis commensurate with
those for which Mr. Toal was eligible while holding those offices. Immediately
following completion of the merger, Mr. Neilson will receive

     - options to purchase 120,000 shares of Dime United stock at the closing
       price on the first trading day after completion of the merger, with
       one-third of these options to vest on the date Mr. Neilson becomes
       Chairman of the Board and Chief Executive Officer and, provided that he
       continues to hold such offices, one-third on the first anniversary of
       such date and the remaining one-third on December 31, 2004, and

     - the right to purchase, at par value of $0.01 per share, 100,000 shares of
       restricted stock of Dime United, with restrictions to lapse on one-third
       of the restricted shares on each of the first, second and third
       anniversaries of the grant date, provided Mr. Neilson is still employed
       pursuant to his employment agreement on those dates, subject to the
       exceptions explained below.

Based on a 56% Dime/44% Hudson weighted average of volatility and an assumed
January 31, 2000 grant date, the Black Scholes value of Mr. Neilson's stock
option grant would be $1,276,275. Based on the January 31, 2000 closing price of
Hudson stock, his restricted shares would be valued at $2,336,500.

     Mr. Neilson also will participate in Dime United's SERP, with a pension
goal of not less than 50% of average compensation, as described under "Agreement
with Mr. Toal" on page 56, offset by benefits received under other defined
benefit plans, including plans of Hudson, such as the Hudson Supplemental
Employees' Retirement Plan. Under the terms of Dime United's SERP, Mr. Neilson
will receive credit for his years of service at Hudson. As of the date of this
document, Mr. Neilson had completed 16 years of service with Hudson, which will
result in his benefit under the SERP being 100% vested at the completion of the
merger.

     If Mr. Neilson's employment is involuntarily terminated other than for
cause or if Mr. Neilson terminates his employment following a material change,
which is defined to include a failure to elect, re-elect, appoint or reappoint
Mr. Neilson to the positions specified above, a material diminution in his
responsibilities, other material breaches of the employment agreement, requiring
his services to be
                                       57
<PAGE>   67

performed primarily outside the New York metropolitan area, or adoption of a
resolution by a simple majority of the board of directors of Dime United or
DimeBank providing that he shall not become Chairman of the Board and Chief
Executive Officer thereof as specified in his agreement, Mr. Neilson will
receive certain specified benefits. These benefits include:

     - a lump sum payment equal to his annual salary in effect immediately prior
       to termination, plus 100% of his annual target bonus;

     - the continuation of life, medical and dental coverage for the remainder
       of the term of his agreement, or 18 months if longer;

     - full vesting of all stock options granted during the term of his
       agreement, continued exercisability of such stock options as if there had
       been no termination of employment and continued vesting of restricted
       stock granted at the completion of the merger as if there had been no
       termination of employment; and

     - if Mr. Neilson's SERP benefit does not then equal at least $741,000
       starting at or after age 55, an additional payment so that his total
       retirement benefit, commencing at or after age 55, expressed as a single
       life annuity, will not be less than that amount.

If Mr. Neilson voluntarily terminates his employment, other than following a
material change, generally no additional benefits will be provided to him.

     If during the term of his agreement and following a change in control, as
defined in his agreement, of Dime United, Mr. Neilson's employment is
involuntarily terminated other than for cause, or he terminates his employment
after a material change, he will be entitled to receive the benefits described
above with respect to an involuntary termination of his employment and
additional benefits, including continued medical coverage for him and his spouse
for the remainder of their lives and, instead of the lump sum described above, a
lump sum equal to three times his rate of annual salary and target bonus, or
average actual bonus, if greater. In addition, Mr. Neilson may receive
reimbursement of costs or expenses if, following a change in control, he must
relocate his principal residence. Neither the execution and delivery of the
merger agreement between Dime and Hudson nor the consummation of the
transactions contemplated by the merger agreement will constitute a change in
control under Mr. Neilson's agreement.

     If any of the compensation and other benefits payable to Mr. Neilson under
his agreement results in additional tax under section 4999 of Internal Revenue
Code, Dime United will make an additional payment so as to provide Mr. Neilson
with the benefits he would have received in the absence of such tax.

     EFFECT OF THE MERGER ON EXISTING DIME AND HUDSON STOCK-BASED RIGHTS,
     INCLUDING STOCK OPTIONS AND STOCK GRANTS

     The merger agreement provides that, on completion of the merger, each
outstanding and unexercised stock option to purchase shares of Dime stock or
Hudson stock granted under Dime's or Hudson's stock-based employee benefit plans
will no longer represent the right to acquire shares of Dime stock or Hudson
stock and will become, respectively, a right to acquire Dime United stock based
on the Dime and Hudson exchange ratios.

     Pursuant to the merger agreement, employee and director options to purchase
shares of Dime stock will be converted at the completion of the merger into
options to purchase 0.60255 of a share of Dime United stock for each share of
Dime stock under the original Dime stock option, and the price for the exercise
of each such Dime United stock option will be equal to the exercise price under
the original Dime stock option divided by 0.60255, subject to any requirements
under the Internal Revenue Code with respect to incentive stock options.

     Pursuant to the merger agreement, employee and director options to purchase
shares of Hudson stock will be converted at the completion of the merger into
options to purchase an equal number of shares of Dime United stock, and the
price for the exercise of each such Dime United stock option will be equal to
the price under the original Hudson stock option.
                                       58
<PAGE>   68

     Approval of the merger agreement by Dime stockholders and Hudson
stockholders will also constitute approval of the conversion of Dime and Hudson
stock options into Dime United stock options as described above and the
assumption by Dime United of the stock-based employee and directors benefit
plans of Hudson.

     Dime.  All outstanding stock options issued under Dime's stock-based
employee and director benefit plans prior to September 15, 1999, that are not
then exercisable will become exercisable at the completion of the merger because
the completion of the merger will constitute a change in control under the terms
of those plans. For those options accompanied by tandem stock appreciation
rights, or SARs, the tandem SARs will be exercisable within 60 days after the
completion of the merger. Any restrictions on restricted stock issued prior to
September 15, 1999 under Dime's stock-based plans will lapse at the completion
of the merger as well. As of September 15, 1999, there were 3,912,428 shares of
Dime stock that were the subject of options granted under Dime's stock-based
plans that were not then exercisable, with 1,044,774 tandem SARs. As of the same
date, there were 401,798 shares of restricted stock issued under Dime's
stock-based plans that remained subject to restrictions. Of these amounts,
options with respect to 862,622 shares of stock, of which 441,696 are
accompanied by tandem SARs, and 45,736 shares of restricted stock have become
exercisable or free of restrictions, or are scheduled to do so, if service
continues, between September 15, 1999 and the date of completion of the merger,
which is currently anticipated to be during the first quarter of 2000. Based on
the $14 1/8 per share closing price of Dime stock on January 31, 2000, options
and restricted stock grants that would not otherwise become exercisable or free
of restrictions prior to the completion of the merger, but will become
exercisable or free of restrictions as of the completion of the merger, have a
value, for options, based on the difference between stock value and exercise
price, of $4.78 million.

     Hudson.  Because the completion of the merger will constitute a change in
control under the terms of Hudson's stock-based employee and director plans, all
outstanding stock options issued under those plans prior to September 15, 1999,
whether or not then otherwise exercisable, will become exercisable at the
completion of the merger. Any restrictions on restricted stock issued prior to
September 15, 1999 under Hudson's stock-based plans will lapse at the completion
of the merger as well. As of September 15, 1999, there were 317,445 shares of
Hudson stock that were the subject of options granted under Hudson's stock-based
plans that were not then exercisable. As of the same date, there were 81,329
shares of restricted stock issued under Hudson's stock-based plans that remained
subject to restrictions. Of these amounts, options with respect to approximately
32,780 shares of stock and no shares of restricted stock have become exercisable
or free of restrictions, or are scheduled to do so, if service continues,
between September 15, 1999 and the date of completion of the merger, which is
currently anticipated to be during the first quarter of 2000. Based on the
$23 3/8 per share closing price of Hudson stock on January 31, 2000, options and
restricted stock grants that would not otherwise become exercisable or free of
restrictions prior to the completion of the merger, but will become exercisable
or free of restrictions as of the completion of the merger, have a value, for
options, based on the difference between stock value and exercise price, of
$11.7 million.

     EFFECTS OF THE MERGER ON EXISTING DIME INCENTIVE PLANS AND SEVERANCE
AGREEMENTS

     In addition to the employment agreement with Mr. Toal described above,
Dime, Dime Savings Bank or their subsidiaries are parties to employment
agreements with 19 officers and change in control agreements with 60 officers,
each of which provides for benefits following a change of control. For the
purposes of each of these agreements, a change in control will occur at the
completion of the merger and was also deemed to have occurred upon the signing
of the merger agreement.

     The employment agreements provide for enhanced severance benefits following
a change in control. Most of these employment agreements extend to March 1,
2002, subject to renewal. If, after a change in control, any of the covered
officers' employment is involuntarily terminated other than for cause, or if any
of the officers terminates his or her employment during the term of the
agreement in effect at the time of the change in control after a decrease in
annual salary or there is a material downgrading of duties or responsibilities,
the enhanced benefits will be payable. Those enhanced benefits include (i)
payment
                                       59
<PAGE>   69

generally equal to two or three times the sum of annual salary and target cash
incentives for which the officer was eligible immediately before the
termination, and (ii) continuation of all life, disability, medical and dental
insurance coverage for the remaining term of the agreement at the time of the
termination, subject to certain conditions specified in the agreements. Vested
stock options will continue to be exercisable for the remainder of their terms,
and there will be continued vesting and exercisability of all non-vested stock
options as if there had not been a termination of service upon the change in
control. A supplemental benefit is provided to make up for any lost vesting in
defined contribution plan benefits provided by Dime. Relocation benefits are
provided in many of the agreements, including those of the executive officers of
Dime.

     Each of the employment agreements described above also provides that, in
the event of a change in control, if an excise tax is payable with respect to
benefits payable under Section 4999 of the Internal Revenue Code because the
amounts are deemed to constitute parachute payments within the meaning of
Section 280G of the Internal Revenue Code, Dime, or Dime United, as the case may
be, will make an additional payment or payments so as to provide the executive
with the benefits he or she would have received in the absence of such tax.
Dime, or Dime United, as the case may be, will not be entitled to a federal
income tax deduction for any excess parachute payments, including any additional
amounts paid pursuant to these gross-up provisions of the employment agreements
with regard to these taxes, including the employment agreements with Mr. Toal
and Mr. Neilson.

     One executive vice president will also receive the enhanced benefits
described above if he voluntarily terminates his employment during the 90-day
period beginning six months after the completion of the merger, provided,
however, that if his employment is terminated by DimeBank within the period
after a timely notice has been received of his intention to leave during his
90-day window period, and the termination is by or at the direction of Mr. Toal
for reasons of his performance other than for cause, the lump sum payment will
equal only two times, rather than three times, his salary and target bonus. If
he terminates his employment voluntarily within the special window period
available for such termination under his employment agreement following the
completion of the merger, while full SERP vesting will not apply, he will be
provided with a benefit to make up any lost vesting in other defined benefit
plans or defined contribution plans maintained by Dime. This same special
vesting benefit is provided to other officers with employment agreements who do
not otherwise participate in the SERP and the special benefit will apply as well
in the event of an involuntary termination of employment or a termination of
employment following a reduction in pay or a material reduction in
responsibilities. Each of the other executive vice presidents of Dime and Dime
Savings Bank participates in Dime's SERP.

     The officers who are parties to change in control agreements with Dime or
its subsidiaries will generally receive a payment ranging from one to two years'
salary and target bonus on an involuntary termination of employment, or a
voluntary termination following a reduction in salary, following a change in
control, as described above. Officers with change in control agreements would
also generally be eligible for continued life, disability, medical and dental
insurance coverage for a stated period after such termination of employment. The
change in control agreements generally provide for cutbacks to avoid excise
taxes on excess parachute payments under Section 280G of the Internal Revenue
Code, and have a current term until March 1, 2001, subject to renewal.

     If the employment of each of the officers covered by agreements described
above were to be terminated in a manner resulting in the payment of all benefits
thereunder, based on the closing price of Dime stock on January 31, 2000 of
$14 1/8 per share, it is anticipated that the aggregate cash payments, other
than SERP benefits, that would be payable to them would be approximately $48.1
million. That total estimated cost, and the other estimated costs described in
this section, would only be incurred if each of the officers terminated
employment under circumstances entitling all of them to the benefits described,
which we believe to be unlikely. If a similar triggering event applied to the
special SERP vesting benefit described above, and it applied to all of the
covered officers other than Mr. Toal, it is estimated that the increased cost of
such SERP vesting would total approximately $15.2 million. We also believe that
it is unlikely that all such employees would terminate service in a manner
entitling them to the SERP vesting. The cost amounts described above have been
calculated on the assumption that the change in control
                                       60
<PAGE>   70

event with respect to Dime will not trigger excise taxes under Section 280G of
the Internal Revenue Code. If such excise taxes were triggered, the cost of the
gross-up for such excise taxes, net of reduction for cutbacks, where appropriate
could, if all eligible employees were entitled to such gross-up, add an
additional $28.4 million in estimated cost.

     For 11 officers of Dime Savings, death benefits provided under the Dime
Savings Bank Key Executive Life Insurance/Death Benefit Plan will be fully
vested at the completion of the merger, or if there is an interim involuntary
termination of service or a termination after a reduction in salary or a
material diminution of duties. The plan provides death benefits of up to six
times annual compensation for certain participants and up to three times annual
compensation for other participants. In the absence of a change in control,
these death benefits would normally vest depending on length of plan
participation, with full vesting only after ten years. Of these participants, if
their employment had continued into, and terminated within the year 2000, death
benefits totaling approximately $16.5 million, or life insurance benefits in a
reduced amount, that would not have been vested will now be vested upon
completion of the merger.

     Dime's voluntary deferred compensation plans also provide for a special
minimum investment return if a deemed investment option is eliminated after the
completion of the merger or the signing of the merger agreement. However, we do
not anticipate that any of the now-available deemed investment options will be
eliminated, and therefore no expense is anticipated because of this protection.
Special valuation rules, based upon the highest closing price of Dime stock
during the 90-day period ending at the completion of the merger, will also apply
with respect to deemed investments in Dime phantom stock under Dime's voluntary
deferred compensation plans for both employees and directors.

     EFFECTS OF THE MERGER ON EXISTING HUDSON SEVERANCE AGREEMENTS

     In addition to the employment agreement with Mr. Neilson described above,
Hudson and Hudson United Bank were, at the time the merger agreement was
executed, parties to agreements with six officers that provide for benefits
following a change of control. If the merger is completed, a change in control
under each of these agreements will be deemed to have occurred 45 days prior to
the date we signed the merger agreement. An officer who resigns before the
merger is completed will not be entitled to any benefits under these agreements.

     Under each of the agreements, Hudson and Hudson United Bank agreed to
employ the officer for a two-year contract period following the change in
control. The officer's title, position, status, duties and authority generally
are to be those in effect immediately prior to the change in control. The
officer's annual salary during the contract period is to be no less than that
prior to the change in control, and the officer's annual bonus is to be as high
as the highest bonus actually paid during any of the three fiscal years prior to
the change in control. Some of the agreements provide that the officer is
entitled to receive an annual bonus equal to the highest bonus to which the
officer would have been entitled during the prior three-fiscal-year period, if
that amount is higher than the highest bonus the officer actually received.

     Severance benefits are payable under these agreements if, during the
contract period, the officer's employment is involuntarily terminated other than
for cause, or if the officer terminates his or her employment for good reason.
The agreements define good reason to include events such as a decrease in
salary, a downgrading of the officer's responsibilities, or a transfer of the
officer to a location more than 25 miles from the officer's present office
location. Two of these agreements also provide for payment of severance benefits
if the officer resigns for any reason during the contract period, so long as the
officer is employed by the company for at least 90 days following completion of
the merger.

     The severance benefits include payment of a lump sum and continuation of
health, hospitalization and medical insurance coverage for a specified time
period, either one or three years, depending on the agreement. The amount of the
lump sum payment varies, depending on the agreement, and ranges from one to
three times the sum of the officer's annual salary immediately prior to the
change in control and the highest bonus actually paid to the officer during any
of the three fiscal years prior to the change in control.

                                       61
<PAGE>   71

     Two of these six change in control agreements contain gross-up provisions.
If an excise tax is payable with respect to benefits payable under Section 4999
of the Internal Revenue Code because the amounts are deemed to constitute
parachute payments within the meaning of Section 280G of the Internal Revenue
Code, the company will make additional payments to provide the officer with the
benefits he or she would have received in the absence of that excise tax. The
company will not be entitled to a federal income tax deduction for any excess
parachute payments, including any additional amounts paid pursuant to the gross-
up provisions of these two agreements regarding such taxes.

     The other four change in control agreements contain a cutback provision.
Under these agreements, if the severance payments and benefits under the
agreement, together with any other parachute payments, would constitute excess
parachute payments under Section 280G of the Internal Revenue Code, the payments
and benefits under the agreement are to be reduced, but not below zero, to the
extent necessary to avoid excess parachute payments.

     In addition to the six agreements described above, Hudson has letter
agreements with two other officers in which Hudson has agreed to provide those
officers with one year of severance pay upon a change in control. In addition,
Hudson has assumed obligations under a number of other agreements with change in
control provisions in connection with its acquisitions of other financial
institutions in recent years.

     One of the six Hudson officers with a change in control agreement reached
an agreement with Hudson on an early resignation and payment in settlement of
his contract. If the employment of each other Hudson officer covered by either a
change in control agreement or one of the letter or other agreements described
above were to be terminated in a manner resulting in the payment of all benefits
thereunder, it is anticipated that the aggregate cash payments that would be
payable to them and to the officer who reached an early settlement would be
approximately $8.5 million. That total estimated cost would only be incurred if
each of the officers terminated employment under circumstances entitling all of
them to the benefits described, which we believe to be unlikely. The costs
described above have been calculated on the assumption that the change in
control event will not trigger excise taxes under Section 280G of the Internal
Revenue Code. If such excise taxes were triggered, the cost of the gross-up for
such excise taxes, net of reduction for cutbacks, where appropriate, could, if
all eligible employees were entitled to such gross-up, add an additional $1.3
million in estimated cost.

     DIME UNITED EMPLOYEE BENEFIT PLANS

     The merger agreement provides that, as promptly as practicable following
the completion of the merger, Dime United and its subsidiaries will adopt
employee benefits plans, including severance plans, or amend existing plans to
provide coverage for persons who become and remain employees of Dime United or
its subsidiaries and who were employees of Hudson or its subsidiaries or
employees of Dime or its subsidiaries immediately prior to the completion of the
merger.

     It is also anticipated that severance benefits will be provided to other
employees whose employment is terminated in connection with the merger. While
Dime and Hudson have had different policies with respect to the provision of
severance benefits, it is anticipated that upon completion of the merger a
unified policy will apply for employees not covered by individual agreements
whose employment is terminated in connection with the merger. The benefits
provided will initially not be less favorable than those that would have been
available to employees of Dime or Hudson, respectively, prior to the completion
of the merger.

     INDEMNIFICATION AND DIRECTORS' AND OFFICERS' INSURANCE

     The merger agreement provides that Dime United will indemnify each present
and former director and officer of Dime, Hudson and their respective
subsidiaries against all costs or expenses, including attorneys' fees or other
liabilities incurred, in connection with any claim arising out of matters
existing at or prior to the completion of the merger, and for six years from the
completion of the merger for such costs arising out of the transactions
contemplated by the merger agreement, to the fullest extent that Dime, Hudson
and their respective subsidiaries are permitted to indemnify their directors and
officers under applicable laws, and their respective certificates of
incorporation or by-laws.
                                       62
<PAGE>   72

     The merger agreement also provides that, for a period of six years
following the merger, Dime United will provide directors' and officers'
liability insurance that serves to reimburse the present and former officers and
directors of Hudson or any of their subsidiaries with respect to claims arising
from facts or events occurring at or prior to the completion of the merger,
which insurance must contain at least the same coverage and amounts, and contain
terms and conditions no less advantageous, as that coverage currently provided
by Hudson.

                              THE MERGER AGREEMENT

     The following describes material provisions of the merger agreement. The
following description of the merger agreement does not purport to be complete
and is subject to, and qualified in its entirety by reference to, the merger
agreement, which is attached as Appendix A and is incorporated by reference in
this document. You are urged to read the merger agreement carefully and in its
entirety.

TERMS OF THE MERGER

     The merger agreement provides for the merger of Hudson into Dime. Dime will
be the surviving corporation after the merger and will be renamed Dime United
Bancorp, Inc. At the time the merger is completed,

     - each outstanding share of Hudson common stock, except for shares, if any,
       owned by Hudson or a subsidiary of Hudson or owned by Dime or a
       subsidiary of Dime, will be converted into one share of Dime United
       common stock, and

     - each issued share of Dime common stock not otherwise retired or
       cancelled, including treasury stock, will be combined into 0.60255 of a
       share of Dime United common stock. Cash will be paid instead of
       fractional shares of Dime United common stock otherwise issuable in the
       merger in exchange for shares of Dime common stock.

POSSIBLE ALTERNATIVE MERGER STRUCTURE

     The merger agreement provides that we may agree to change the structure of
the merger. No change will be made that adversely affects what Dime stockholders
and Hudson stockholders would receive in the merger, unless the change is
presented to and approved by the Dime stockholders and Hudson stockholders prior
to completion of the merger.

AMENDMENT, WAIVER AND TERMINATION OF THE MERGER AGREEMENT

     The provisions of the merger agreement may be waived by the party
benefitted by those provisions. The merger agreement may be amended or modified,
in accordance with applicable law, by our written agreement.

     The merger agreement may be terminated, and the merger abandoned, by us at
any time before the merger is scheduled to be completed if both of our boards of
directors vote to do so. In addition, the merger agreement may be terminated,
and the merger abandoned:

     - by action of a majority of either of our boards of directors if

       - the merger is not consummated by June 30, 2000,

       - any request or application for governmental approval is requested to be
         withdrawn by the governmental agency,

       - any governmental approval or authorization required for the

         intention to deny any governmental approval or authorization, or

         indicates an intention to grant, subject to conditions or restrictions
         that would be materially adverse to Dime United; or

     - by either of us if

       - the other materially breaches any representation, warranty, covenant or
         agreement contained in the merger agreement that would result in the

                                       67
<PAGE>   77

         cannot be or has not been cured within 30 days after the giving of
         written notice of such breach or

       - the board of directors of the other fails to recommend to its
         stockholders the adoption or approval of the merger agreement.

AMENDMENTS TO CERTIFICATE OF INCORPORATION AND BY-LAWS OF DIME

     The merger agreement also provides for amendments to the certificate of
incorporation of Dime to be effected by the merger. In addition, immediately
prior to completion of the merger, the Dime board of directors will amend the
by-laws of Dime effective at the completion of the merger. These amendments will
give effect to agreements concerning the board of directors and management of
Dime United as discussed in "The Merger -- Board and Management of Dime United
and DimeBank" on pages 47-50. In addition, the amendments to Dime's certificate
will change the name of Dime to Dime United Bancorp, Inc. These amendments are
described in Annex 1 and Annex 2 of the merger agreement. Adoption or approval
of the merger agreement will also result in adoption of the amendments to the
Dime certificate of incorporation.

                          THE STOCK OPTION AGREEMENTS

     The following description sets forth the material provisions of each of the
Dime stock option agreement and the Hudson stock option agreement, but does not
purport to be complete and is subject to the full texts of, and qualified in its
entirety by reference to, these agreements, which are attached as Appendices B
and C, respectively, to this document and are incorporated herein by reference.
You are urged to read each of these documents carefully and in their entirety.

GENERAL

     As an inducement for Dime to enter into the merger agreement, Hudson agreed
to grant Dime an option to purchase shares of Hudson stock. As an inducement for
Hudson to enter into the merger agreement, Dime agreed to grant Hudson an option
to purchase shares of Dime stock. Except as otherwise noted below, the terms and
conditions of the Dime stock option agreement and the Hudson stock option
agreement are identical in all material respects.

     Under the Hudson option, Dime can purchase up to 8,139,081 shares of Hudson
common stock. Under the Dime option, Hudson can purchase up to 22,271,682 shares
of Dime stock. Although these numbers are subject to adjustment in certain
cases, including the issuance of additional shares, they will never exceed 19.9%
of the number of shares of Dime or Hudson stock, as the case may be, outstanding
immediately before exercise of the option. The exercise price of the Dime option
is $17 3/4 per share of Dime stock, and the exercise price of the Hudson option
is $29 1/4 per share of Hudson stock, but each per share option price is subject
to adjustment in certain cases, including stock dividends, recapitalizations and
other changes in capitalization. These exercise prices were determined by using
the closing prices for Dime stock and for Hudson stock on September 14, 1999,
the day before the merger was announced. Because Hudson announced a 3% stock
dividend after the date of these stock option agreements, the exercise price of
the Hudson option was automatically adjusted, pursuant to provisions of the
Hudson stock option agreement, to take into account the change in price of
Hudson stock that resulted from this dividend. The Hudson exercise price of
$29 1/4 reflects this adjustment.

PURPOSE OF THE STOCK OPTION AGREEMENTS

     Arrangements such as the stock option agreements are customarily entered
into in connection with announced mergers involving publicly traded companies to
increase the likelihood that the transactions will be completed in accordance
with their terms and to compensate the grantee for the efforts undertaken and
the expenses and losses incurred by it if the transaction is not completed. The
stock option agreements may have the effect of discouraging offers by third
parties to acquire the issuer of the option, even if those persons were prepared
to offer consideration to the issuer's stockholders that has a greater value
than what

                                       68
<PAGE>   78

these stockholders will receive in the merger. Also, following consultation with
our respective independent accountants, we believe that the exercise or
repurchase of either of the stock options is likely to prohibit another acquiror
from accounting for any acquisition of the issuer of the stock option using the
pooling-of-interests accounting method for a period of two years.

     To our best knowledge, no event giving rise to the right to exercise either
option has occurred as of the date of this document.

EXERCISE; EXPIRATION

     Each of Dime and Hudson can exercise its option if both an initial
triggering event and a subsequent triggering event occur prior to the occurrence
of an exercise termination event, as these terms are described below. The
purchase of any shares of Dime stock and Hudson stock pursuant to the options is
subject to compliance with applicable law.

     The option agreements describe a number of different events as initial
triggering events. Generally, an initial triggering event will occur when the
issuer of the option enters into, proposes to enter into, or is the subject of
an acquisition transaction or a proposed acquisition transaction.

     As used in the stock option agreements, the term acquisition transaction
means:

     - a merger or consolidation or any similar transaction, involving the
       issuer, other than certain mergers involving only the issuer and its
       subsidiaries;

     - a purchase, lease or other acquisition of all or any substantial part of
       the assets or deposits of the issuer or any of its subsidiaries; or

     - a purchase or other acquisition of securities representing 10% or more of
       the voting power of the outstanding common stock of the issuer or any of
       its subsidiaries.

     The stock option agreements generally define the term subsequent triggering
event to mean any of the following events or transactions:

     - the acquisition by a third party of beneficial ownership of 25% or more
       of the outstanding common stock of the issuer or

     - the issuer or any of its subsidiaries, without the prior written consent
       of the grantee, enters into an agreement to engage in an acquisition
       transaction with a third party, or the board of directors of the issuer
       recommends that its stockholders approve or accept any acquisition
       transaction, other than the merger, provided that, for purposes of this
       definition of subsequent triggering event, the percentage referred to in
       the third definition of acquisition transaction above shall be 25% rather
       than 10%.

     The stock option agreements define the term exercise termination event to
mean any of the following:

     - completion of the merger;

     - termination of the merger agreement in accordance with its terms if
       before an initial triggering event, provided that this would not include
       a termination of the merger agreement by the grantee based on a willful
       breach by the issuer of a representation, warranty, covenant or other
       agreement contained in the merger agreement; or

     - the passage of 18 months, subject to extension in order to obtain
       required regulatory approvals, after termination of the merger agreement
       if the termination follows the occurrence of an initial triggering event
       or is a termination of the merger agreement by the grantee based on a
       willful breach by the issuer of a representation, warranty, covenant or
       other agreement contained in the merger agreement.

     If an option becomes exercisable, it may be exercised in whole or in part
within six months following the subsequent triggering event. The grantee's right
to exercise the option and certain other rights under

                                       69
<PAGE>   79

the respective stock option agreement are subject to an extension in order to
obtain required regulatory approvals and comply with applicable regulatory
waiting periods and to avoid liability under the short-swing trading
restrictions contained in Section 16(b) of the Securities Exchange Act. The
option price and the number of shares issuable under the option are subject to
adjustment in the event of specified changes in the capital stock of the issuer.
Nevertheless, the grantee may not exercise the option if it is in breach of any
of its covenants or agreements under the merger agreement.

RIGHTS OF THE GRANTEE OF THE OPTION

     At any time after a repurchase event, as this term is described below, upon
the request of the grantee, the issuer may be required to repurchase the option
and all or any part of the shares issued under the option from the grantee. The
repurchase of the option will be at a price per share equal to the amount by
which the option repurchase price, as that term is defined in the stock option
agreement, exceeds the option price. The term repurchase event is defined to
mean:

     - the acquisition by any third party of beneficial ownership of 50% or more
       of the outstanding shares of the issuer's common stock or

     - the consummation of an acquisition transaction, provided that for
       purposes of the definition of repurchase event, the percentage referred
       to in the third definition of acquisition transaction above shall be 25%
       rather than 10%.

     The stock option agreements also provide that the grantee of the option
may, at any time within 90 days after a repurchase event, surrender the option
and any shares issued under the option held by the grantee for a cash fee equal
to $50 million, adjusted if there have been purchases of stock under the option
and gains on sales of stock purchased under the option.

     If prior to an exercise termination event the issuer enters into certain
transactions in which it is not the surviving corporation, certain fundamental
changes in its capital stock occur, or the issuer sells all or substantially all
of its or its significant subsidiaries' assets, the option will be converted
into or exchangeable for a substitute option, at the grantee's election, of

     - the continuing or surviving person of a consolidation or merger with the
       issuer,

     - the acquiring person in a plan of exchange in which the issuer is
       acquired,

     - the issuer in a merger or plan of exchange in which the issuer is the
       acquiring person,

     - the transferee of all or substantially all of the assets of the issuer or
       its significant subsidiary, or

     - any person that controls any of these entities, as the case may be.

     The substitute option will have the same terms and conditions as the
original option. However, if the terms of the substitute option cannot be the
same as those of the option by law, the terms of the substitute option will be
as similar as possible and at least as advantageous to the grantee.

                    DESCRIPTION OF DIME UNITED CAPITAL STOCK

     In this section, we describe material features and rights of the Dime
United capital stock after the merger. Because Dime is the surviving corporation

except as otherwise noted. This summary is qualified in its entirety by
reference to applicable Delaware law, Dime's Amended and Restated Certificate of
Incorporation, Dime's by-laws, the rights agreement, as described below, and
Annexes 1 and 2 to the merger agreement, which annexes include changes to Dime's
governing documents that will be part of Dime United's governing documents. See

to dividends when, as and if declared by the Dime United board of directors,

outstanding. Dime United's ability to pay dividends will be limited by certain
restrictions imposed on Delaware corporations. Under these restrictions,
dividends may be paid only out of a Dime United surplus, as defined by the
Delaware General Corporation Law or if there is no surplus, Dime United's net

distributions, if any, from DimeBank, and such dividends and other capital
distributions will be subject to regulatory restrictions. See "Regulation and
Supervision of Dime United -- Regulatory Capital Requirements" on pages 83-84
and "Regulation and Supervision of Dime United -- Limitations on Capital
Distributions" on page 84.

United remaining after a liquidation, dissolution or winding up of Dime United,
subject to creditors rights and any rights of any holders of Dime United
preferred stock that may be outstanding.

National Bank of Boston. Each right will entitle its holder to purchase
one-hundredth of a share of participating preferred stock of Dime United at an
exercise price of $50, subject to adjustment, after the separation time, which
is after the close of business on the earlier of

     - the tenth business day after commencement of a tender or exchange offer
       that, if consummated, would result in a person becoming an acquiring
       person, which is defined in the rights agreement as a person beneficially
       owning 20% or more of the outstanding shares of Dime United common stock;
       and

     - the tenth business day after the first date of public announcement that a
       person has become an acquiring person, which is also called the flip-in
       date.

     The rights will not be exercisable until the business day following the
separation time. The rights will expire on the earlier of

     - the close of business on November 6, 2005;

     - redemption, as described below;

     - an exchange for common stock, as described below; or

     - the merger of Dime United into another corporation pursuant to an
       agreement entered into prior to a flip-in date.

The Dime United board of directors may, at any time prior to occurrence of a
flip-in date, redeem all the rights at a price of $0.01 per right.

     If a flip-in date occurs, each right, other than those held by the
acquiring person or any affiliate or associate of the acquiring person or by any
transferees of any of these persons, will constitute the right to purchase
shares of Dime United common stock having an aggregate market price equal to
$100 in cash, subject to adjustment. In addition, the Dime United board of
directors may at any time between a flip-in date and the time that an acquiring
person becomes the beneficial owner of more than 50% of the outstanding shares
of Dime United common stock elect to exchange the rights for shares of Dime
United common stock at an exchange ratio of one share of Dime United common
stock per right.

     Under the rights agreement, Dime United may not consolidate or merge, or
engage in other similar transactions, with an acquiring person without entering
into a supplemental agreement with the acquiring person providing that, upon
consummation or occurrence of the transaction, each right shall thereafter
constitute the right to purchase common stock of the acquiring person having an
aggregate market price equal to $100 in cash, subject to adjustment.

     The rights will not prevent a takeover of Dime United. The rights, however,
may have antitakeover effects. The rights may cause substantial dilution to a
person or group that acquires 20% or more of the outstanding Dime United common
stock unless the rights are first redeemed by the Dime United board of
directors.

     A description of the rights agreement specifying the terms of the rights
has been included in reports filed by Dime under the Securities Exchange Act.
See "Where You Can Find More Information" on page 100.

     The rights agreement currently applies to Dime stock but has not been
triggered by the merger with Hudson because Hudson would not be deemed an
acquiring person under the rights agreement. The rights agreement will remain in
place without modification after completion of the merger with Hudson.

               MATERIAL DIFFERENCES IN THE RIGHTS OF DIME UNITED
                      STOCKHOLDERS AND HUDSON STOCKHOLDERS

     At the completion of the merger, Hudson stockholders automatically will
become stockholders of Dime United and their rights as stockholders will be
determined by Dime United's certificate of incorporation, Dime United's by-laws
and Delaware law, instead of by Hudson's certificate of incorporation, Hudson's
by-laws and New Jersey law. The following is a summary of the material
differences in the rights of stockholders of Dime United and stockholders of
Hudson.

     Because Dime is the surviving corporation in the merger, the rights of Dime
United stockholders will be the same as the rights of the Dime stockholders,
except as otherwise noted.

     This summary is necessarily general and does not purport to be a complete
discussion of, and is qualified in its entirety by reference to, the Delaware
General Corporation Law, the New Jersey Business Corporation Act, the
certificate of incorporation and by-laws of each corporation, including the
amendments to Dime's certificate of incorporation to be effected by the merger
pursuant to provisions of the merger agreement and to Dime's by-laws to be
effected by the Dime board of directors effective at the completion of the
merger, as well as Dime's rights agreement.

     The New Jersey Business Corporation Act refers to holders of stock as
shareholders, while the Delaware General Corporation Law uses the term
stockholders. To make this document easier to read, we have used the term
stockholder throughout.

to recommend a person for election to the board of
directors at an annual or special meeting of
stockholders, the person must have been nominated in
accordance with special nominating committee
procedures. In addition, certain provisions of the
Dime United certificate of incorporation will require
that the Dime United board of directors designate
directorships or otherwise use efforts to maintain
the ratio of former Dime directors to former Hudson
directors that will exist at the completion of the
merger. These special nominating committee procedures
and ratio maintenance requirements will survive until
December 31, 2002 and are described in this document
in "The Merger -- Board and Management of Dime United
and DimeBank" on pages 47-50. Dime's governing
documents do not currently include such special
nominating committee procedures or ratio maintenance
requirements.

      DISCUSSION OF ANTITAKEOVER PROTECTION IN DIME UNITED CERTIFICATE OF
                           INCORPORATION AND BY-LAWS

GENERAL

     Certain provisions of Dime United's certificate of incorporation and
by-laws described above in "Description of Dime United Capital Stock" on pages
71-73 and "Material Differences in the Rights of Dime United Stockholders and
Hudson Stockholders" on pages 73-81 may have antitakeover effects. These
provisions may discourage attempts by others to acquire control of Dime United
without negotiation with Dime United's board of directors. The effect of these
provisions is discussed briefly below. In addition to these provisions of the
Dime United certificate of incorporation and by-laws, the rights agreement
discussed in "Description of Dime United Capital Stock -- Stockholder Protection
Rights Plan" on pages 72-73 may also have antitakeover effects. All of the
provisions discussed below are contained in Dime's certificate of incorporation
and by-laws currently.

AUTHORIZED STOCK

     The shares of Dime United common stock and Dime United preferred stock
authorized by Dime United's certificate of incorporation but not issued will
provide the Dime United board of directors with flexibility to effect certain
financings, acquisitions, stock dividends, stock splits and stock-based grants
without the need for a stockholder vote. The Dime United board of directors,
consistent with its fiduciary duties, could also authorize the issuance of these
shares, and could establish voting, conversion, liquidation and other rights for
the Dime United preferred stock being issued, in an effort to deter attempts to
gain control of Dime United.

CLASSIFICATION OF BOARD OF DIRECTORS; NO CUMULATIVE VOTING

     Dime United's certificate of incorporation and by-laws will provide that
the directors of Dime United will be divided into three classes of as nearly
equal size as possible, with one class elected annually to serve for a term of
three years. The classification of the Dime United board of directors may
discourage a takeover of Dime United because a stockholder with a majority
interest in Dime United would have to wait for at least two consecutive annual
meetings of stockholders to elect a majority of the members of the Dime United
board of directors. Dime United's certificate of incorporation also will not
authorize cumulative voting for the election of directors of Dime United.

SIZE OF BOARD; VACANCIES; REMOVAL OF DIRECTORS

     The provisions of Dime United's certificate of incorporation and by-laws
giving the Dime United board of directors the power to determine the exact
number of directors and to fill any vacancies or newly created positions, and
allowing removal of directors only for cause upon a supermajority vote of
stockholders are intended to insure that the classified board provisions
discussed above are not circumvented by the removal of incumbent directors.
Furthermore, since Dime United stockholders will not have the ability to call
special meetings of stockholders, a stockholder seeking to have a director
removed for cause generally will be able to do so only at an annual meeting of
stockholders. These provisions could make the removal of any director more
difficult, even if such removal were desired by the stockholders of Dime United.
In addition, these provisions of Dime United's certificate of incorporation and
by-laws could make a takeover of Dime United more difficult under circumstances
where the potential acquiror seeks to do so through obtaining control of the
Dime United board of directors.

SPECIAL MEETINGS OF STOCKHOLDERS

     The provisions of Dime United's certificate of incorporation and by-laws
relating to special meetings of stockholders are intended to enable the Dime
United board of directors to determine if it is appropriate for Dime United to
incur the expense of a special meeting in order to present a proposal to Dime
United stockholders. If the Dime United board of directors determines not to
call a special meeting, stockholder

                                       81
<PAGE>   91

proposals could not be presented to the stockholders for action until the next
annual meeting because stockholders cannot call a special meeting. In addition,
these provisions could make a takeover of Dime United more difficult under
circumstances where the potential acquiror seeks to do so through obtaining
control of the Dime United board of directors.

STOCKHOLDER ACTION BY UNANIMOUS WRITTEN CONSENT

     The purpose of the provision in Dime's certificate of incorporation
requiring unanimity in a stockholder written consent is to prevent any person or
persons holding the percentage of the voting stock of Dime United otherwise
required to take corporate action from taking such action without giving notice
to other stockholders and without the procedures of a stockholder meeting. In a
publicly held corporation with many stockholders, the practical effect of
requiring 100% of the stockholders to consent to any action in writing is that
stockholders can act only at a duly held stockholder meeting.

AMENDMENT OF CERTIFICATE OF INCORPORATION AND BY-LAWS

     The requirements in Dime United's certificate of incorporation and by-laws
for a supermajority stockholder vote for the amendment of certain provisions of
Dime United's certificate of incorporation and Dime United's by-laws is intended
to prevent a stockholder controlling a majority of the Dime United stock from
avoiding the requirements of important provisions of Dime United's certificate
of incorporation or by-laws simply by amending or repealing them. Thus, the
holders of a minority of the shares of the Dime United stock could block the
future repeal or modification of Dime United's by-laws and certain provisions of
the certificate of incorporation even if such action were deemed beneficial by
the holders of more than a majority, but less than two-thirds, of the Dime
United stock.

                   REGULATION AND SUPERVISION OF DIME UNITED

     Dime United will be a bank holding company. The following discussion sets
forth the material elements of the regulatory framework applicable to bank
holding companies and their subsidiaries and incorporates by reference certain
information relevant to Dime and Hudson prior to the merger. This regulatory
framework is intended primarily for the protection of depositors and the federal
deposit insurance funds and not for the protection of security holders. To the
extent that the following information describes statutory and regulatory
provisions, it is qualified in its entirety by reference to those provisions. A
change in the statutes, regulations or regulatory policies applicable to Dime
United or its subsidiaries may have a material effect on its business. Further
information is contained in the documents incorporated by reference into this
document. See "Where You Can Find More Information" on page 100.

     Hudson is currently a bank holding company and it is subject to regulation
under the Bank Holding Company Act and to inspection, examination and
supervision by the Federal Reserve Board. Hudson United Bank is a New
Jersey-chartered commercial bank subject to inspection, examination and
supervision by the FDIC, at the federal level, and the New Jersey Department of
Banking and Insurance, at the state level. For further information regarding
regulation and supervision of Hudson and its subsidiaries prior to the merger,
see discussions in the documents incorporated by reference into this document,
such as Hudson's Annual Report on Form 10-K, as amended, for the year ended
December 31, 1998. See "Where You Can Find More Information" on page 100.

     Dime is currently a savings and loan holding company and it and Dime
Savings Bank are subject to regulation under the Home Owners' Loan Act and to
inspection, examination and supervision by the Office of Thrift Supervision. For
further information regarding regulation and supervision of Dime and its
subsidiaries prior to the merger, see discussions in the documents incorporated
by reference into this document, such as Dime's Annual Report on Form 10-K for
the year ended December 31, 1998. See "Where You Can Find More Information" on
page 100.

GENERAL

     As the sole owner of DimeBank, Dime United will be a bank holding company
and will be subject to regulation under the Bank Holding Company Act, and to
inspection, examination and supervision by the Federal Reserve Board. DimeBank
will be a New Jersey chartered commercial bank subject to primary federal
regulation by the FDIC and primary state regulation by the New Jersey Department
of Banking and Insurance. Dime United and its subsidiaries also will be affected
by the fiscal and monetary policies of the federal government and the Federal
Reserve Board and by various other governmental requirements and regulations.

     Under the Bank Holding Company Act, bank holding companies generally may
not acquire the ownership or control of more than 5% of the voting shares or
substantially all the assets of any company, including a bank, without the
Federal Reserve Board's prior approval. In addition, bank holding companies
generally may engage, directly or indirectly, only in banking and those other
activities that are determined by the Federal Reserve Board to be closely
related to banking.

     As a bank holding company, Dime United's ability to pay dividends and make
other distributions on its stock will be largely dependent on its ability to
receive dividends and other funds from DimeBank. Dime United's ability to pay
dividends and other distributions on its stock therefore will be affected by
statutes and regulations relating to the business of DimeBank that have the
effect of limiting transfers of funds from DimeBank to Dime United. The nature
and extent of these restrictions will depend upon DimeBank's level of regulatory
capital and its income.

REGULATORY CAPITAL REQUIREMENTS

     Dime United will be subject to risk-based capital requirements and
guidelines imposed by the Federal Reserve Board, which are substantially similar
to the capital requirements and guidelines imposed by the FDIC on the depository
institutions within its jurisdiction. For this purpose, a depository
institution's or holding company's assets and certain specified
off-balance-sheet commitments and obligations are assigned to various risk
categories. A depository institution's or holding company's capital, in turn, is
classified in one of three tiers: core, or Tier 1, capital, which includes
common equity, non-cumulative perpetual preferred stock, a limited amount of
cumulative perpetual preferred stock at the holding company level and minority
interests in equity accounts of consolidated subsidiaries, less goodwill, and
most intangible assets; supplementary, or Tier 2, capital, which includes, among
other items, perpetual preferred stock not meeting the Tier 1 definition,
mandatorily convertible securities, subordinated debt and allowances for loan
and lease losses, subject to certain limitations; and market risk, or Tier 3,
capital, which includes qualifying unsecured subordinated debt.

     Bank holding companies currently are required to maintain Tier 1 capital
and total capital (the sum of Tier 1, Tier 2 and Tier 3 capital) equal,
respectively, to at least 4% and 8% of its total risk-weighted assets, including
certain off-balance-sheet items, such as standby letters of credit. In addition,
in order for a holding company or depository institution to be considered well
capitalized for regulatory purposes, its Tier 1 and total capital ratios must be
6% and 10% on a risk-adjusted basis, respectively.

     The Federal Reserve Board and the FDIC have adopted rules to incorporate
market and interest rate risk components into their risk-based capital
standards. Under market risk requirements, capital will be allocated to support
the amount of market risk related to a financial institution's ongoing trading
activities.

     The Federal Reserve Board also requires bank holding companies to maintain
a minimum leverage ratio (Tier 1 capital to adjusted total assets) of 3% if the
holding company has the highest regulatory rating and meets certain other
requirements, or of 3% plus an additional cushion of at least 100 to 200 basis
points if the holding company does not meet these requirements.

     The Federal Reserve Board may set capital requirements higher than the
minimum noted above for holding companies whose circumstances warrant it. For
example, holding companies experiencing or anticipating significant growth may
be expected to maintain capital positions substantially above the minimum
supervisory levels without significant reliance on intangible assets.
Furthermore, the Federal
                                       83
<PAGE>   93

Reserve Board has indicated that it will consider a tangible Tier 1 capital
leverage ratio, deducting all intangibles, and other indicia of capital strength
in evaluating proposals for expansion or new activities.

     DimeBank will be subject to similar risk-based and leverage capital
requirements adopted by the FDIC.

     Failure to meet capital requirements could subject a bank to a variety of
enforcement remedies, including the termination of federal deposit insurance and
to certain restrictions on its business under "prompt corrective action"
guidelines by the federal banking regulators.

LIMITATIONS ON CAPITAL DISTRIBUTIONS

     Various federal and state statutory provisions limit the amount of
dividends that DimeBank will be able to pay to Dime United without regulatory
approval.

     Under federal law, a state bank that is not a member of the Federal Reserve
System, such as DimeBank, cannot make any distribution or dividend if, following
such distribution or dividend, the bank would be undercapitalized under the laws
and regulations regarding regulatory capitalization of the bank. Under New
Jersey law, as applicable to DimeBank, a bank's board may determine dividends on
capital stock of the bank in its discretion. However, no dividend shall be paid
if:

     - the capital stock of the bank would be impaired and

     - the payment of such dividend would reduce the surplus of the bank, as
       calculated under New Jersey law, or the payment of such dividend would
       cause the surplus of the bank, as calculated under New Jersey law, to be
       less than 50% of its capital stock.

     In addition, federal bank regulatory authorities will have authority to
prohibit DimeBank from engaging in unsafe or unsound practices in conducting its
business. The payment of dividends, depending upon the financial condition of
DimeBank, could be deemed an unsafe or unsound practice. The ability of DimeBank
to pay dividends could be further influenced by bank regulatory policies and
capital guidelines.

TRANSACTIONS WITH AFFILIATES

     Under federal law and regulation, transactions between a bank, such as
DimeBank, and its affiliates, which term includes its holding company, Dime
United, and other companies controlled by its holding company, are subject to
quantitative and qualitative restrictions. Banks are restricted in their ability
to engage in certain types of transactions with their affiliates, including
transactions that could provide funds to a holding company for the payment of
capital distributions. These covered transactions include

     - lending or extending credit to an affiliate,

     - purchasing assets from an affiliate,

     - accepting securities issued by an affiliate as collateral for a loan or
       extension of credit, and

     - issuing a guarantee, acceptance or letter of credit on behalf of an
       affiliate.

     Covered transactions are permitted between a bank and a single affiliate up
to 10% of the capital stock and surplus of the bank, and between a bank and all
of its affiliates up to 20% of the capital stock and surplus of the bank. The
purchase of low-quality assets by a bank from an affiliate is not permitted.
Each loan or extension of credit to an affiliate by a bank must be secured by
collateral with a market value ranging from 100% to 130% of the amount of credit
extended, depending on the type of collateral.

     Covered transactions between a bank and an affiliate, and other
transactions with or benefitting an affiliate, must be on terms and conditions
at least as favorable to the bank as those prevailing at the time for comparable
transactions with non-affiliated companies. This arm's-length requirement
applies to all covered transactions, as well as to

     - the sale of securities or other assets to an affiliate,

                                       84
<PAGE>   94

     - the payment of money or the furnishing of services to an affiliate,

     - any transaction in which an affiliate acts as agent or broker or receives
       a fee for its services to the bank or to any other person, or

     - any transaction or series of transactions with a third party if any
       affiliate has a financial interest in the third party or is a participant

     Under the Riegle-Neal Interstate Banking and Branching Efficiency Act of
1994, subject to specified requirements:

     - bank holding companies, such as Dime United, are permitted to acquire
       banks and bank holding companies located in any state;

     - any bank that is a subsidiary of a bank holding company is permitted to
       receive deposits, renew time deposits, close loans, service loans and
       receive loan payments as an agent for any other bank subsidiary of that
       holding company, although some restrictions apply to federal savings
       associations acting as agent for other bank subsidiaries of that bank
       holding company; and

     - banks are permitted to acquire branch offices outside their home states
       by merging with out-of-state banks, by purchasing branches in other
       states and by establishing new, or de novo, branches in other states.
       Under the Riegle-Neal Act, each state had the opportunity either to opt
       out of this provision, thereby prohibiting interstate branching in such
       states, or to opt in at an earlier time, thereby allowing interstate
       branching within that state. Furthermore, a state may opt in with respect
       to de novo branching, thereby permitting a bank to open new branches in a
       state in which the bank does not already have a branch. If a state
       chooses not to opt in to de novo branching, then a bank can only enter
       that state by acquiring an existing bank or branch.

     DimeBank will also be subject to the requirements of New Jersey law
regarding opening new branches in New Jersey or outside New Jersey. In addition,
DimeBank will be subject to the requirements of each state for branching into
that state, including whether that state has chosen to opt in to de novo
branching.

ACQUISITION OF CONTROL

     Before any company may acquire more than 5% of the voting securities of a
bank holding company such as Dime United, that company must obtain approval of
the Federal Reserve Board. Also, under the Change in Bank Control Act, before
any person may acquire control of Dime United, as a bank holding company, it
must submit 60 days' prior written notice to the Federal Reserve Board and such
notice must not be disapproved.

RECENT LEGISLATION

     On November 12, 1999, the President signed the Gramm-Leach-Bliley Financial
Modernization Act of 1999 into law. The Modernization Act will:

     - allow bank holding companies meeting management, capital and Community
       Reinvestment Act standards to engage in a substantially broader range of
       nonbanking activities than currently is permissible, including insurance
       underwriting and making merchant banking investments in commercial and
       financial companies;

     - allow insurers and other financial services companies to acquire banks;

     - remove various restrictions that currently apply to bank holding company
       ownership of securities firms and mutual fund advisory companies; and

                                       85
<PAGE>   95

     - establish the overall regulatory structure applicable to bank holding
       companies that also engage in insurance and securities operations.

This part of the Modernization Act will become effective on March 11, 2000. The
Modernization Act also modifies other current financial laws, including laws
related to financial privacy and community reinvestment. The new financial
privacy provisions will generally prohibit financial institutions, including us,
from disclosing nonpublic personal financial information to third parties unless
customers have the opportunity to opt out of the disclosure.

     Dime United will, during the regular course of its business, evaluate the
potential opportunities presented by the Modernization Act, including evaluating
its ability to engage in additional permitted activities or to acquire other
companies engaged in additional permitted activities.

DIVIDEND POLICY OF DIME UNITED

     We currently contemplate that the combined company, Dime United, will pay
cash dividends at an annual rate of $1.00 per share, although the Dime United
board of directors may change this dividend policy at any time. During 1999,
Hudson paid cash dividends of $1.00 per share, before the impact of its 3% stock
dividend, and Dime paid cash dividends of $0.23 per share. Dime United
stockholders will be entitled to receive dividends when and if declared by the
Dime United board of directors out of funds legally available for dividends. The
Dime United board of directors will periodically consider the payment of
dividends, taking into account Dime United's financial condition and level of
net income, Dime United's future prospects, economic conditions, industry
practices and other factors, including applicable banking laws and regulations
as discussed in "Regulation and Supervision of Dime United" on pages 82-86.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION

     The following unaudited pro forma combined condensed financial information
is presented to show the effect of the merger on the historical financial
position and results of operations of Dime and Hudson under the
pooling-of-interests method of accounting. The unaudited pro forma combined
condensed financial information combines the historical financial information of
Dime and Hudson, after giving effect to the assumptions and adjustments
contained in the accompanying notes to unaudited pro forma combined condensed
financial information, as of September 30, 1999 and for the nine months ended
September 30, 1999 and 1998 and for the years ended December 31, 1998, 1997, and
1996, respectively. The unaudited pro forma combined condensed balance sheet
gives effect to the merger as if it had been completed on September 30, 1999 and
the unaudited pro forma combined condensed statements of income give effect to
the merger as if the merger had been consummated at the beginning of the
earliest period presented. The historical information of Hudson includes
supplemental and restated financial information of Hudson, filed on Forms 8-K on
December 15, 1999 and January 28, 2000, reflecting the completion of the
acquisitions of JeffBanks and Southern Jersey Bancorp. See "Where You Can Find
More Information" on page 100.

     The merger, which is expected to be completed in the first quarter of 2000,
provides for the exchange of 0.60255 shares of Dime United common stock for each
share of Dime common stock and provides for the exchange of one share of Dime
United common stock for each outstanding share of Hudson common stock. The pro
forma combined condensed financial information as of September 30, 1999 and for
the nine months ended September 30, 1999 and 1998 and each of the three years
ended December 31, 1998, 1997 and 1996 is based on and derived from, and should
be read in conjunction with the historical consolidated financial statements and
the related notes of Dime and Hudson, which are incorporated by reference
herein. See "Where You Can Find More Information" on page 100.

     The pro forma data are presented for comparative purposes only and are not
necessarily indicative of the future financial position or results of operations
of the combined company or of the combined financial position or the results of
operations that would have been realized had the merger been consummated during
the periods or as of the date for which the pro forma data are presented.

     The pro forma financial information begins on the next page.

                          NOTES TO UNAUDITED PRO FORMA
                    COMBINED CONDENSED FINANCIAL INFORMATION

NOTE 1 -- BASIS OF PRESENTATION

     The unaudited pro forma combined condensed financial information has been
prepared giving effect to the merger of Dime and Hudson under the
pooling-of-interests method of accounting and the assumptions and adjustments
described in these notes. The merger was assumed to be consummated as of
September 30, 1999 for purposes of the unaudited pro forma combined condensed
balance sheet and as of the beginning of the earliest period presented for
purposes of the unaudited pro forma combined condensed statements of income.

     The unaudited pro forma combined condensed financial information is
presented for comparative purposes only and is not necessarily indicative of the
combined financial position or results of operations in the future or of the
combined financial position or results of operations that would have occurred
had the merger been in effect at or for the periods presented.

     The unaudited pro forma combined condensed financial information does not
reflect Dime Saving Bank's acquisition of 28 branches of KeyBank effective as of
October 18, 1999, Hudson United Bank's acquisition of substantially all of the
assets of Lyon Credit Corporation that occurred on October 22, 1999 or Hudson
United Bank's acquisition of loans and other financial assets, and assumption of
deposits, of Advest Bank and Trust that occurred on December 1, 1999.
Information regarding these transactions has not been included because they do
not present significant acquisitions in the context of the pro forma financial
information and because separate financial statements for the assets acquired
and the liabilities assumed are not prepared by the companies from which such
assets and liabilities were acquired. For information about these acquisitions,
see "Information About Dime and Hudson" beginning on page 17.

     The unaudited pro forma combined condensed financial information also does
not give effect to anticipated cost savings and opportunities to increase
revenues associated with the merger. As a result of the merger, cost savings of
$78 million annually are expected to be realized of which $38 million are
expected to be achieved for the year 2000 and $78 million are expected to be
achieved for the year 2001. Of the $78 million of cost savings, $42 million is
associated with personnel costs, largely reflecting the expected elimination of
approximately 550 positions, and $14 million is associated with the elimination
of redundant facilities, equipment and systems. The remaining $22 million are
expected to be achieved through reductions in various general and administrative
expense categories, primarily marketing, regulatory assessments as a result of
relinquishment by Dime Savings Bank of its thrift charter, and professional
fees. Additional cost savings are expected to be achieved in connection with the
mergers of Hudson and JeffBanks and Hudson and Southern Jersey Bancorp.

     In order to conform presentations, certain reclassifications have been made
in the unaudited pro forma combined condensed balance sheet and statements of
income to the historical classifications of Dime and Hudson. Further, Dime and
Hudson are in the process of reviewing their accounting policies and financial
statement classifications and, upon completion thereof, adjustments to the
unaudited pro forma combined condensed financial information may be necessary to
conform to those accounting policies and classifications.

NOTE 2 -- MERGER-RELATED AND RESTRUCTURING CHARGES

     The following table summarizes the merger-related and restructuring charges
currently anticipated to be recorded in connection with the merger of Dime and
Hudson (in thousands):

<TABLE>
<S>                                                           <C>
Pre-tax expense:
  Facilities, equipment and systems costs                     $ 62,400
  Personnel costs                                               40,000
  Investment banking, legal, accounting and consulting fees     32,000
  Other costs                                                    2,000
                                                              --------
Total pre-tax expense                                          136,400
Income tax benefit attributable to total pre-tax expense       (54,500)
Income tax expense attributable to recapture of bad debt
  reserve                                                       12,000
                                                              --------
Total merger-related and restructuring charges                $ 93,900
                                                              ========
</TABLE>

     Facilities, equipment and systems costs include charges associated with the
consolidation of duplicative banking branches and other operational facilities,
write-offs of redundant computer hardware and software and the termination of
certain systems-related contracts. Facilities-, equipment- and systems-related
asset write-downs are currently expected to be, in the aggregate, approximately
$33 million, representing the carrying value of such assets.

     Personnel costs are largely associated with charges for severance benefits,
employment contracts and the vesting of restricted stock of Dime and Hudson in
connection with the merger. It is currently expected that approximately 550
positions will be eliminated over a one year period in connection with the
merger. The most substantial reductions in staff are anticipated to be in the
areas of duplicative operations and support for retail banking, mortgage banking
and information technology. The remaining staff reductions are largely
associated with various corporate administrative and back-office operations.

     Simultaneously with the merger, Dime Savings Bank will merge with and into
Hudson United Bank. At such time, Dime Savings Bank will relinquish its thrift
charter, resulting in the recapture of its existing bad debt reserve.

     Additionally, merger-related and restructuring charges associated with the
mergers of Hudson and JeffBanks and Hudson and Southern Jersey Bancorp are, in
the aggregate, currently anticipated to be approximately $70 million on a
pre-tax basis and $48 million on an after-tax basis. These charges are comprised
of personnel, facilities, equipment, systems, professional and other costs,
including increases in the allowance for loan losses to conform the related
accounting policies of JeffBanks and Southern Jersey Bancorp to those of Hudson.

     The merger-related and restructuring charges associated with the mergers of
Dime and Hudson, Hudson and JeffBanks and Hudson and Southern Jersey Bancorp
have been reflected in the unaudited pro forma combined condensed balance sheet
at September 30, 1999; however, since these charges are non-recurring in nature,
they have not been reflected in the unaudited pro forma combined condensed
statements of income.

NOTE 3 -- PRO FORMA ADJUSTMENTS

     At September 30, 1999, Hudson owned 2,010,100 shares of Dime common stock.
The following adjustments were made to the unaudited pro forma combined
condensed balance sheet to reclassify these shares from securities available for
sale to treasury stock and to eliminate the related unrealized gain, net of
taxes: (i) securities available for sale were reduced by $35.2 million; (ii)
accumulated comprehensive loss was increased by $0.6 million; (iii) other assets
was increased by $0.3 million; and (iv) treasury stock was increased by $34.3
million. No dividend income was recognized by Hudson on these shares.

                                       97
<PAGE>   107

     The following adjustments were made to the unaudited pro forma combined
condensed balance sheet in order to reflect the impact of merger-related and
restructuring charges associated with the merger, as well as the mergers of
Hudson and JeffBanks and Hudson and Southern Jersey Bancorp: (i) retained
earnings was reduced by $141.8 million; (ii) unearned compensation and ESOP
shares was reduced by $8.4 million; (iii) other liabilities was increased by
$100.4 million; and (iv) the allowance for loan losses was increased by $33.0
million.

     The unaudited pro forma combined condensed balance sheet was further
adjusted for the merger of Dime and Hudson as follows: (i) treasury stock was
reduced by $63.5 million, additional paid-in capital was reduced by $59.9
million and common stock was reduced by $3.6 million to reflect the elimination
of 2,009,212 shares of Hudson common stock held in treasury; and (ii) additional
paid-in capital was increased by $90.2 million and common stock was reduced by
$90.2 million to reflect the issuance of 123,215,678 shares of Dime United
common stock, including 6,933,789 shares placed in Dime United's treasury, with
a par value of $0.01 per share, the elimination of 120,252,459 issued shares of
Dime common stock with a par value of $0.01 per share and the elimination of
50,757,559 outstanding shares of Hudson common stock with a stated value of
$1.778 per share. Hudson's shares of common stock held in treasury and
outstanding shares of common stock reported above do not reflect the 3% stock
dividend paid by Hudson on December 1, 1999. As a result of this stock dividend,
Hudson's shares of common stock held in treasury were increased by 53,377 and
its outstanding shares of common stock were increased by 1,218,933.

NOTE 4 -- EARNINGS PER SHARE

     The pro forma combined weighted average basic and diluted common shares
outstanding reflect Dime's historical weighted average shares, as adjusted for
the Dime exchange ratio of 0.60255 and the shares of Dime common stock held by
Hudson, plus Hudson's historical weighted average shares, which have been
retroactively restated to give effect to the 3% stock dividend paid by Hudson on
December 1, 1999.

                                    EXPERTS

     The consolidated financial statements of Dime and its subsidiaries as of
December 31, 1998 and 1997 and for each of the years in the three-year period
ended December 31, 1998 included in Dime's 1998 Annual Report on Form 10-K have
been incorporated by reference in this document in reliance upon the report of
KPMG LLP, independent certified public accountants, found in Dime's 1998 Annual
Report on Form 10-K which is incorporated by reference in this document, and
upon the authority of KPMG LLP as experts in accounting and auditing.

     The consolidated financial statements of Hudson as of December 31, 1998 and
1997 and for each of the years in the three-year period ended December 31, 1998
have been incorporated by reference in this document and have been audited by
Arthur Andersen LLP, independent public accountants, as indicated in their
reports with respect thereto, and are included herein in reliance upon the
authority of said firm as experts in accounting and auditing.

     Dime expects representatives of KPMG LLP to attend Dime's special meeting,
and Hudson expects representatives of Arthur Andersen LLP to attend Hudson's
special meeting. These representatives will have an opportunity to make a
statement if they desire to do so, and we expect that they will be available to
respond to any appropriate questions you may have.

                      VALIDITY OF DIME UNITED COMMON STOCK

     The validity of the shares of Dime United common stock to be issued in the
merger will be passed upon by Sullivan & Cromwell, New York, New York, counsel
to Dime in connection with the merger.

                                 OTHER MATTERS

     As of the date of this document, the Dime board of directors and the Hudson
board of directors know of no matters that will be presented for consideration
at their respective special meetings other than as described in this document.
However, if any other matter shall properly come before these special meetings
or any adjournments or postponements thereof and shall be voted upon, the
proposed proxy will be deemed to confer authority to the individuals named as
authorized therein to vote the shares represented by the proxy as to any matters
that fall within the purposes set forth in the notice of special meeting.
However, no proxy that is voted against the merger agreement will be voted in
favor of any adjournment or postponement.

DIME 2000 ANNUAL MEETING STOCKHOLDER PROPOSALS

     In order to be considered for inclusion in Dime's proxy statement for the
annual meeting of stockholders to be held in 2000, all stockholder nominations
and proposals must have been submitted to the Secretary of Dime at Dime's
offices at 589 Fifth Avenue, New York, New York 10017, on or before December 2,
1999. If the merger is completed as expected in the first quarter of 2000, this
meeting will be the first annual meeting of Dime United stockholders. Under
Dime's by-laws, stockholder nominations for director and stockholder proposals
not included in Dime's 2000 proxy statement, in order to be considered for
possible action by stockholders at the 2000 annual meeting of stockholders, must
be submitted to Dime's Secretary, at the address set forth above, not less than
60 nor more than 90 days in advance of March 31, 2000. In addition, stockholder
nominations and stockholder proposals must meet other applicable criteria set
forth in Dime's by-laws in order to be considered at the 2000 annual meeting.
Dime's board of directors will review any stockholder proposals that are filed
as required and will determine whether such proposals meet applicable criteria
for consideration at the 2000 annual meeting.

HUDSON 2000 ANNUAL MEETING STOCKHOLDER PROPOSALS

     If the merger is completed as expected in the first quarter of 2000, Hudson
will no longer exist, and therefore the next annual stockholders meeting will be
of Dime United stockholders.

                                       99
<PAGE>   109

     If the merger has not occurred by March 31, 2000, it is expected that
Hudson's annual stockholder meeting will be scheduled to take place on or about
May 10, 2000. New Jersey law requires that the notice of regular or special
stockholders' meeting specify the purpose or purposes of such meeting. Thus,
stockholder proposals must be referred to in Hudson's notice of stockholder's
meeting for such proposal to be properly considered at a meeting of
stockholders.

     Any Hudson stockholder that wishes to have a proposal included in Hudson's
notice of stockholder's meeting, proxy statement and proxy card for its 2000
Annual Meeting must submit the proposal to Hudson by the applicable deadline.
The deadline was November 16, 1999. However, the deadline is subject to change
as noted below.

     If Hudson changes its 2000 Annual Meeting date to a date more than 30 days
from the date of its 1999 Annual Meeting, then the deadline will be changed to a
reasonable time before Hudson begins to print and mail its proxy materials. If
Hudson changes the date of its 2000 Annual Meeting in a manner which alters the
deadline, Hudson will so state under Item 5 of the first quarterly report on
Form 10-Q it files with the SEC after the date change or will notify its
stockholders in another reasonable manner.

of 1933, as amended ("HOLA").

     B.  Hudson.  Hudson has been duly incorporated and is an existing
corporation in good standing under the laws of the State of New Jersey, with its
principal executive offices located in Mahwah, New Jersey. As of the date
hereof, Hudson has 100 million authorized shares of common stock, no par value
("Hudson Common Stock"), of which not more than 40,899,905 shares are

     C.  The Merger.  At the Effective Time (as defined in Section 1.2), the

with and into Dime, with Dime the surviving corporation of the Merger. At and
after the Effective Time, Dime, as the surviving corporation in the Merger, is
referred to herein as the "Surviving Corporation". The name of the Surviving
Corporation shall be "Dime United Bancorp, Inc."

     D.  Stock Option Agreements.  As an inducement to and condition of Hudson's
willingness to enter into this Agreement and the Hudson Stock Option Agreement
(as defined in the following sentence), Dime will grant to Hudson an option
pursuant to a Stock Option Agreement (the "Dime Stock Option Agreement"). As an
inducement to and condition of Dime's willingness to enter into this Agreement
and the Dime Stock Option Agreement, Hudson will grant to Dime an option

The Stock Option Agreements will be entered into immediately following the

as amended (the "Internal Revenue Code").

     F.  Approvals.  The Boards of Directors of Dime and Hudson (at meetings
duly called and held) have determined that this Agreement and the transactions
contemplated hereby are in the best interests of Dime and Hudson, respectively,
and their respective stockholders and have approved this Agreement and the Stock
Option Agreements.

     G.  Subsidiary Bank.  It is the intention of the parties that the Surviving
Corporation shall be a bank holding company registered pursuant to the BHCA and
that the operation of the federal savings bank subsidiary of Dime and the New
Jersey state-chartered commercial bank subsidiary of Hudson shall be combined,
in a manner to be determined, so that the primary depository institution
subsidiary of the Surviving Corporation is a New Jersey state-chartered
commercial bank (the "Subsidiary Bank"). It is the intention of the parties that
the Board of Directors of the Surviving Corporation and the Board of Directors
of the Subsidiary Bank shall be the same, until otherwise modified, and that the
charter and by-
<PAGE>   121

laws of the Subsidiary Bank shall contain those provisions (or other provisions
of similar effect) discussed in Article III hereof with respect to the Surviving
Corporation.

     NOW, THEREFORE, in consideration of the premises, and of the
representations, warranties, covenants and agreements set forth herein, the
parties hereto agree as follows:

                                   ARTICLE IV

               CONVERSION OR CANCELLATION AND EXCHANGE OF SHARES

     4.1  Conversion or Cancellation of Shares.  At the Effective Time, by
virtue of the Merger and without any action on the part of any stockholder of
either Dime or Hudson:

          (a) Each share of Dime Common Stock issued and not retired or canceled
     immediately prior to the Effective Time, including treasury stock, shall be
     combined into 0.60255 (the "Exchange Ratio") of a fully paid and
     nonassessable share of common stock, par value $0.01 per share, of the
     Surviving Corporation ("Surviving Corporation Common Stock").

          (b) Other than Exception Shares, each share of Hudson Common Stock
     outstanding immediately prior to the Effective Time shall be converted into
     and constitute one fully paid and nonassessable share of Surviving
     Corporation Common Stock. Each holder of a certificate representing any
     such shares of Hudson Common Stock shall cease to have any rights with
     respect thereto, except that, from and after the Effective Time,
     certificates representing Hudson Common Stock, other than Exception Shares,
     immediately prior to the Effective Time shall be deemed for all purposes to
     represent the number of shares of Surviving Corporation Common Stock into
     which they were converted pursuant to this Section. "Exception Shares"
     means shares of Hudson Common Stock held by Hudson or any of its
     subsidiaries or by Dime or any of its subsidiaries, in each case other than
     in a fiduciary capacity or in satisfaction of a debt previously contracted
     in good faith.

          (c) Each share of Hudson Common Stock constituting an Exception Share
     immediately prior to the Effective Time shall be canceled and retired at
     the Effective Time and no consideration shall be issued in exchange
     therefor.

          (d) Holders of certificates formerly representing Hudson Common Stock
     shall not be required to exchange such certificates for certificates
     representing Surviving Corporation Common Stock, provided, however, that if
     an exchange of such certificates is required by law or applicable rule or
     regulation, the parties will cause the Surviving Corporation to arrange for
     such exchange on a one-share-for-one-share basis. Holders of certificates
     representing the Dime Common Stock referred to in Section 4.1(a) ("Old
     Certificates") shall exchange such Old Certificates for certificates
     representing shares of Surviving Corporation Common Stock ("New
     Certificates") in the manner described in Section 4.2.

          (e) In the event that, subsequent to the date of this Agreement but
     prior to the Effective Time, the shares of Dime Common Stock or Hudson
     Common Stock issued and outstanding shall, through a reorganization,
     recapitalization, reclassification, stock dividend, stock split, reverse
     stock split, or other similar change in the capitalization of Dime or
     Hudson, as the case may be, increase or decrease in number or be changed
     into or exchanged for a different issue or number of securities, then an
     appropriate and proportionate adjustment shall be made to the Exchange
     Ratio.

     4.2  Exchange of Old Certificates for New Certificates.  (a) Appointment of
Exchange Agent. From the Effective Time until the end of the one-year period
following the Effective Time, the Surviving Corporation shall make available to
an exchange agent (which may be a subsidiary bank of the Surviving Corporation)
appointed prior to the Effective Time by Dime and Hudson jointly on behalf of
the Surviving Corporation (the "Exchange Agent") New Certificates and cash in
amounts sufficient to allow the
                                       A-4
<PAGE>   124

Exchange Agent to make all deliveries of New Certificates and payments that may
be required in exchange for Old Certificates pursuant to this Article IV. At the
end of such one-year period, any such New Certificates and cash remaining in the
possession of the Exchange Agent (together with any dividends or earnings in
respect thereof) shall be returned to the Surviving Corporation. Any former
holders of Old Certificates who have not theretofore exchanged their Old
Certificates for New Certificates and cash pursuant to this Article IV shall
thereafter be entitled to look exclusively to the Surviving Corporation, and
only as general creditors thereof, for the shares of Surviving Corporation
Common Stock and any cash to which they become entitled upon exchange of their
Old Certificates pursuant to this Article IV.

     (b)  Exchange Procedures.  Promptly after the Effective Time, the Surviving
Corporation shall cause the Exchange Agent to mail or deliver to each person who
was, immediately prior to the Effective Time, a holder of record of Dime Common
Stock, a form (mutually agreed upon by Dime and Hudson) of letter of transmittal
containing instructions for use in effecting the surrender of Old Certificates
in exchange for New Certificates and any payments pursuant to this Article IV.
Upon surrender to the Exchange Agent of an Old Certificate for cancellation
together with such letter of transmittal, duly executed and completed in
accordance with the instructions thereto, the holder of such Old Certificate
shall be entitled to receive in exchange therefor a New Certificate representing
the shares of Surviving Corporation Common Stock, and a check in the amount, if
any, to which such holder is entitled pursuant to this Article IV, and the Old
Certificate so surrendered shall forthwith be canceled. No interest will be paid
or will accrue on any amount payable upon surrender of Old Certificates. If any
New Certificate or cash payment is to be issued or made in a name other than
that in which the Old Certificate surrendered in exchange therefor is
registered, it shall be a condition of such exchange that the person requesting
such exchange shall pay any transfer or other taxes required by reason of the
issuance of such New Certificate or the making of such cash payment in a name
other than that of the registered holder of the Old Certificate surrendered, or
shall establish to the satisfaction of the Surviving Corporation that any such
taxes have been paid or are not applicable. An Affiliate (as defined in Section
6.15) of Dime shall not be entitled to receive any New Certificate or payment
pursuant to this Article IV until such Affiliate shall have duly executed and
delivered an appropriate agreement described in Section 6.15.

     (c)  Fractional Shares.  Upon giving effect to the combination and exchange
described in Section 4.1(a), the resulting number of shares of Surviving
Corporation Common Stock of each registered holder of Dime Common Stock shall be
rounded down to the nearest whole number and each such registered holder shall
be entitled to receive from the Surviving Corporation in lieu of any fractional
share of Surviving Corporation Common Stock prior to such rounding down an
amount in cash (without interest) equal to the product obtained by multiplying
(a) the fraction of a share of Surviving Corporation Common Stock to which such
holder would otherwise be entitled and (b) the average of the closing price per
share of Hudson Common Stock for the ten trading days most recently preceding
the Closing Date as reported on the New York Stock Exchange, Inc. (the "NYSE")
Composite Transactions reporting system. Notwithstanding the foregoing,
fractional shares of Surviving Corporation Common Stock that would be issued
into a dividend reinvestment plan, 401(k) plan or other similar stock plan
maintained by Dime prior to the Effective Time shall be issued within such plan
as a fractional share of Surviving Corporation Common Stock at the Effective
Time.

     (d)  Transfers.  At or after the Effective Time, there shall be no
transfers on the stock transfer books of the Surviving Corporation of the shares
of Hudson Common Stock which were outstanding immediately prior to the Effective
Time.

     (e)  No Liability.  In the event that any Old Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such Old Certificate to be lost, stolen or destroyed and, if
required by the Surviving Corporation, the posting by such person of a bond in
such reasonable amount as the Surviving Corporation may direct as indemnity
against any claim that may be made against it with respect to such Old
Certificate, the Surviving Corporation shall, in exchange for such lost, stolen

on the part of any holder of any such option or warrant, each option or warrant

terms as the original Dime Option):

          (a) the number of shares of Surviving Corporation Common Stock to be
     subject to the new option or warrant shall be equal to the product of (1)
     the number of shares of Dime Common Stock purchasable upon exercise of the

Closing Date. With respect to any Dime Options that are "incentive stock

adjustments shall be effected in a manner consistent with Section 424(a) of the
Internal Revenue Code.

delivered to Hudson and Hudson has delivered to Dime a schedule (respectively,
its "Disclosure Schedule") setting forth, among other things, items the
disclosure of which is necessary or appropriate either in response to an express
disclosure requirement contained in a provision hereof or as an exception to one
or more representations or warranties contained in Section 5.3 or to one or more
of its covenants contained in Article VI; provided that (1) no such item is
required to be set forth in a Disclosure Schedule 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 standard established by Section 5.2, and (2) the mere inclusion of an item
in a Disclosure Schedule as an exception to a representation or warranty shall
not be deemed an admission by a party that such item represents a material
exception or fact, event or circumstance or that such item is reasonably likely
to result in a Material Adverse Effect.

     (b) "Material Adverse Effect" shall mean with respect to Dime, Hudson or
the Surviving Corporation any effect that (1) is material and adverse to the
financial position, results of operations or business of Dime and its
subsidiaries taken as a whole, Hudson and its subsidiaries taken as a whole or
the Surviving Corporation and its subsidiaries taken as a whole, respectively,
or (2) would materially impair the ability

<PAGE>   126

of either Dime or Hudson to perform its obligations under this Agreement or
otherwise materially threaten or materially impede the consummation of the
Merger and the other transactions contemplated by this Agreement; provided,
however, that Material Adverse Effect shall not be deemed to include the impact
of (A) changes in banking and similar laws of general applicability or
interpretations thereof by courts or governmental authorities, (B) changes in
generally accepted accounting principles or regulatory accounting requirements
applicable to depository institutions and their holding companies generally, (C)
actions or omissions of Dime or Hudson taken with the prior written consent of

and (E) the effects of any change attributable to or resulting from changes in
economic conditions applicable to depository institutions or their holding
companies generally or in general levels of interest rates, except to the extent
that the effect of such change is materially more severe for Dime, Hudson or the
Surviving Corporation, as the case may be, than for depository institutions or
their holding companies generally.

     (c) "Previously Disclosed" by a party shall mean information set forth on
its Disclosure Schedule corresponding to the provision of this Agreement to
which such information relates; provided that information which, on its face,

in Section 5.3 shall be deemed untrue or incorrect, and no party hereto shall be

event, individually or taken together with all other facts, circumstances or
events inconsistent with any representation or warranty contained in Section 5.3
has had or is reasonably likely to result in a Material Adverse Effect.

     circulated by it with respect to periods since January 1, 1997 through the
     date of this Agreement and will promptly deliver each such registration
     statement, offering circular, report, definitive proxy statement or
     information statement filed, used or circulated after the date hereof
     (collectively, its "Reports"), each in the form (including exhibits and any
     amendments thereto) filed with the SEC (or if not so filed, in the form
     used or circulated).

     investigations or hearings of, before or by any Governmental Entity, or
     civil, criminal or administrative actions, suits, claims or proceedings of,

     its knowledge, threatened, against it or any of its subsidiaries; and
     neither it nor any of its subsidiaries (nor any officer, director,

     similar submission to, any Governmental Entity charged with the supervision
     or regulation of depository institutions or engaged in the insurance of

     issuing or requesting (or is considering the appropriateness of issuing or
     requesting) any such order, decree, agreement, memorandum of understanding,
     commitment letter or similar submission.

          (m) Taxes.  (1) The term "Tax" or "Taxes" includes any tax or similar

     to a tax sharing or similar agreement or any agreement pursuant to which it
     or any of its subsidiaries has indemnified any party (other than it or one
     of its subsidiaries) with respect to Taxes. The proper and accurate amounts
     have been or will be withheld from all employees (and timely paid to the
     appropriate Governmental Entity or set aside in an account for such
     purposes) for all periods through the Closing Date in compliance with all
     Tax withholding provisions of applicable federal, state, local and foreign
     laws (including, without limitation, income, social security and employment
     tax withholding for all types of compensation).

          (n) Insurance.  Each of it and its subsidiaries has taken all
     requisite action (including without limitation the making of claims and the
     giving of notices) pursuant to its directors' and officers' liability
     insurance policy or policies in order to preserve all rights thereunder
     with respect to all matters (other than matters arising in connection with
     this Agreement and the transactions

                                      A-12
<PAGE>   132

     contemplated hereby) that are known to it. It has Previously Disclosed a
     list of all directors' and officers' liability insurance policies
     maintained by it or its subsidiaries.

          (o) Labor Matters.  Neither it nor any of its subsidiaries is a party
     to, or is bound by, any collective bargaining agreement, contract or other
     agreement or understanding with a labor union or labor organization, nor is
     it or any of its subsidiaries the subject of any material proceeding
     asserting that it or any such subsidiary has committed an unfair labor
     practice or seeking to compel it or such subsidiary to bargain with any
     labor organization as to wages or conditions of employment, nor is there
     any strike involving it or any of its subsidiaries pending or, to its
     knowledge, threatened, nor is it aware of any activity involving its or any
     of its subsidiaries' employees seeking to certify a collective bargaining
     unit or engaging in any other organizational activity.

          (p) Employee Benefits.  (1) As of the date of this Agreement, it has
     Previously Disclosed a list of all bonus, deferred compensation, pension,
     retirement, profit-sharing, thrift, savings, employee stock ownership,
     stock bonus, stock purchase, restricted stock and stock option plans, all
     material employment or severance contracts, consulting agreements and all
     other material employee benefit plans that cover employees, former
     employees, directors or independent contractors (and their spouses,
     dependents or beneficiaries) of it and its subsidiaries (its "Compensation
     Plans"). True and complete copies of the Compensation Plans (and, as
     applicable, copies of summary plan descriptions, governmental filings (on
     Form 5500 series or otherwise), actuarial reports and reports under
     Financial Accounting Standards Board Statement No. 106 relating thereto)
     and all other benefit plans, contracts or arrangements (regardless of
     whether they are funded or unfunded or foreign or domestic) covering
     current or former employees, directors or independent contractors (and
     their spouses, dependents or beneficiaries) of it or its subsidiaries (its
     "Employees"), including, but not limited to, "employee benefit plans"
     within the meaning of Section 3(3) of the Employee Retirement Income
     Security Act of 1974, as amended ("ERISA"), and all amendments thereto,
     have been made available to the other party.

          (2) Except as disclosed in its Reports or as provided in this
     Agreement, the transactions contemplated by this Agreement and the Stock
     Option Agreements will not result in the vesting or acceleration of any
     amounts under any Compensation Plan, any material increase in benefits
     under any Compensation Plan or payment of any severance or similar
     compensation under any Compensation Plan.

          (3) All of its and its subsidiaries' employee benefit plans, within
     the meaning of Section 3(3) of ERISA, other than "multiemployer plans"
     within the meaning of Section 3(37) or 4001(a)(3) of ERISA, covering
     Employees (collectively, its "Plans") are in compliance with the applicable
     provisions of ERISA and the Internal Revenue Code, and other applicable
     laws in all material respects. Each of its Plans which is an "employee
     pension benefit plan" within the meaning of Section 3(2) of ERISA ("Pension
     Plan") and which is intended to be qualified under Section 401(a) of the
     Internal Revenue Code has received a favorable determination letter from
     the Internal Revenue Service, and it is not aware of any circumstances
     likely to result in revocation of any such favorable determination letter.
     There is no pending or, to its knowledge, threatened litigation relating to
     its Plans. Neither it nor any of its subsidiaries has engaged in a
     transaction with respect to any Plan that could subject it or any of its
     subsidiaries to a tax or penalty imposed by either Section 4975 of the
     Internal Revenue Code or Section 502(i) of ERISA.

          (4) No liability under Subtitle C or D of Title IV of ERISA (other
     than payment of applicable premiums) has been or is expected to be incurred
     by it or any of its subsidiaries with respect to any ongoing, frozen or
     terminated "single-employer plan", within the meaning of Section
     4001(a)(15) of ERISA, currently or formerly maintained by any of them, or
     the single-employer plan of any entity which is considered one employer
     with it under Section 4001 of ERISA or Section 414 of the Internal Revenue
     Code (an "ERISA Affiliate"). It and its subsidiaries and ERISA Affiliates
     have not incurred and do not expect to incur any material withdrawal
     liability with respect to a multiemployer plan under Subtitle E of Title IV
     of ERISA (regardless of whether based on contributions of an

                                      A-13
<PAGE>   133

     ERISA Affiliate), nor has it or any of its subsidiaries or ERISA Affiliates
     been notified by any multiemployer plan to which it or any of its
     subsidiaries or ERISA Affiliates is contributing, or may be obligated to
     contribute, that such multiemployer plan is currently in reorganization or
     insolvency under and within the meaning of Section 4241 or 4245 of ERISA or
     that such multiemployer plan intends to terminate or has been terminated
     under Section 4041A of ERISA. No notice of a "reportable event", within the
     meaning of Section 4043 of ERISA, for which the 30-day reporting
     requirement has not been waived, has been required to be filed for any of
     its Pension Plans or by any of its ERISA Affiliates within the 12-month
     period ending on the date hereof. Neither it, its subsidiaries nor any of
     their respective ERISA Affiliates has incurred or is aware of any facts
     that are reasonably likely to result in any liability pursuant to Section
     4069 or 4204 of ERISA.

          (5) All material contributions required to be made by it and its
     subsidiaries under the terms of any of its Plans have been timely made or
     have been reflected on its Financial Statements. Neither any of its Pension
     Plans nor any single-employer plan of any of its ERISA Affiliates has an
     "accumulated funding deficiency" (whether or not waived) within the meaning
     of Section 412 of the Internal Revenue Code or Section 302 of ERISA. None
     of it, its subsidiaries or its ERISA Affiliates has provided, or is
     required to provide, security to any Pension Plan or to any single-employer
     plan of an ERISA Affiliate pursuant to Section 401(a)(29) or 412(f)(3) of
     the Internal Revenue Code or Section 306, 307 or 4204 of ERISA.

          (6) Under each of its and its ERISA Affiliates' Pension Plans which is
     a single-employer plan, as of the last day of the most recent plan year
     ended prior to the date of this Agreement, the actuarially determined
     present value of all "benefit liabilities", within the meaning of Section
     4001(a)(16) of ERISA (as determined on the basis of the actuarial
     assumptions contained in the Pension Plan's most recent actuarial
     valuation), did not exceed the then current value of the assets of such
     Pension Plan, and to its knowledge, there has been no change in the
     financial condition of such Pension Plan since the last day of the most
     recent plan year which reasonably could be expected to change such
     conclusion. There would be no withdrawal liability of it and its
     subsidiaries under each benefit plan which is a multiemployer plan to which
     it, its subsidiaries or its ERISA Affiliates has contributed during the
     preceding 12 months, if such withdrawal liability were determined as if a
     "complete withdrawal", within the meaning of Section 4203 of ERISA, had
     occurred as of the date hereof.

          (7) Except as disclosed in its Reports, neither it nor its
     subsidiaries have any obligations for retiree health and life benefits.

          (8) There are no restrictions on the rights of it or its subsidiaries
     to amend or terminate any Plan without incurring any liability thereunder
     in addition to normal liabilities for benefits.

     except for (A) the Stock Option Agreements, and (B) arrangements made after

          (t) Knowledge as to Conditions.  (1) As of the date of this Agreement,
     it knows of no reason why any regulatory approvals and, to the extent
     necessary, any other approvals, authorizations, filings, registrations, and
     notices should not be obtained without the imposition of any condition or
     restriction described in the proviso to Section 7.1(b), or why the

     counsel referred to in Sections 7.2(d) and 7.3(c) cannot be obtained.

          (2) In the case of the representations and warranties made by Hudson,

     Bank, a New Jersey bank and wholly owned subsidiary of Hudson, JeffBanks,
     Inc., a Pennsylvania corporation, Jefferson Bank, a Pennsylvania bank and

     Hudson United Bank and Southern Jersey Bancorp of Delaware, Inc., a
     Delaware corporation, and Farmers and Merchants National Bank, a national
     banking association, should not be consummated. In case either or both of
     the Pending Transactions shall fail to be consummated, such mere failure,

     Agreement or give Dime any right of termination hereunder.

          (u) Year 2000 Compliance.  (1) All computer software and hardware used
     in its businesses is Year 2000 Compliant (as defined below) or is

     Compliant prior to December 31, 1999.

          (2) It has disclosed to the other party its plans for evaluating
     whether the business conducted by it or its subsidiaries is Year 2000
     Compliant. Neither it or its subsidiaries has received any written notice
     or, to its knowledge, oral notice from any Governmental Entity which
     indicates that such Governmental Entity considers or would consider the
     businesses conducted by it or its subsidiaries not to be Year 2000
     Compliant.

          (3) "Year 2000 Compliant" means, with respect to any computer software
     or hardware and other processing capabilities of a party, that such
     software or hardware and processing capabilities are able, in all material
     respects, accurately to process date and time data (including calculating,
     comparing, and sequencing) from, into and between the years 1999 and 2000
     and leap year calculations, and will not generate erroneous data or cause a
     system to fail because of a date of the year 1999 or greater or spanning
     the years 1999 and 2000.

          (v) Brokers and Finders.  None of it, its subsidiaries or any of their
     officers, directors or employees has employed any broker or finder or
     incurred any liability for any brokerage fees, commissions or finder's fees
     in connection with the transactions contemplated herein, except that Hudson
     has retained Goldman, Sachs & Co. as its financial advisor and Dime has
     retained Credit Suisse First Boston as its financial advisor, the
     arrangements with which have been disclosed in writing to the other party
     prior to the date hereof.

     6.1  Conduct of Business Pending the Effective Time.  Each of Dime and
Hudson agrees as to itself and its subsidiaries that, from and after the date
hereof until the Effective Time, except insofar as the other party shall
otherwise consent in writing (such consent not to be unreasonably withheld or
delayed) or except as otherwise expressly contemplated by this Agreement or the
Stock Option Agreements or as Previously Disclosed:

          (a) The business of it and its subsidiaries will be conducted only in
     the ordinary and usual course and, to the extent consistent therewith, it
     and its subsidiaries will use all reasonable efforts to preserve intact
     their business organizations and assets and maintain their rights,
     franchises and existing relations with customers, suppliers, employees and
     business associates and to take no action that would (1) adversely affect
     the ability of any of them to obtain any necessary approvals of
     Governmental Entities required for the transactions contemplated hereby
     without imposition of a condition or restriction of the type referred to in
     the proviso to Section 7.1(b), (2) adversely affect its ability to perform
     its obligations under this Agreement or the Stock Option Agreements or (3)
     be reasonably likely to result in a Material Adverse Effect.

          (b) It will not (1) sell or pledge or agree to sell or pledge or
     permit any Lien to exist on any stock owned by it of any of its material
     subsidiaries; (2) amend its certificate of incorporation or by-laws; (3)
     split, combine or reclassify any outstanding capital stock; (4) other than
     as permitted by Section 6.2, declare, set aside or pay any dividend payable
     in cash, stock or other property with respect to any of its capital stock;
     or (5) repurchase, redeem or otherwise acquire, or permit any subsidiary to
     purchase or otherwise acquire, directly or indirectly, any shares of its
     capital stock or any securities convertible into or exercisable for any
     shares of its capital stock (other than such capital stock repurchased
     pursuant to the Dime Stock Plans and the Hudson Stock Plans, as the case
     may be).

          (c) Notwithstanding anything to the contrary contained in Section 6.3,
     neither it nor any of its subsidiaries will (1) issue, sell, pledge,
     dispose of or encumber, or authorize or propose the issuance, sale, pledge,
     disposition or encumbrance of, any shares of, or securities convertible or
     exchangeable for, or options, warrants, calls, commitments or rights of any
     kind to acquire, any shares of its capital stock of any class, with the
     exception of Dime Common Stock or Hudson Common Stock issuable as of the
     date hereof pursuant to the Dime Stock Plans or Hudson Stock Plans,
     respectively, consistent with past practice, and the Stock Option
     Agreements; (2) transfer, lease, license, guarantee, sell, mortgage, pledge
     or dispose of any other material property or assets or encumber any
     property or assets other than to a direct or indirect wholly owned
     subsidiary of it; (3) cancel, release, assign or modify any material amount
     of indebtedness of any other individual, corporation or other entity
     (collectively, a "Person") other than in the ordinary and usual course of
     business; or (4) authorize capital expenditures other than in the ordinary
     and usual course of business.

          (d) Except as expressly contemplated in this Agreement and except for
     internal reorganizations involving existing subsidiaries, neither it nor
     any of its subsidiaries will make any material acquisition of, or
     investment in, assets or stock of any other Person not in the ordinary and
     usual course of business.

          (e) Other than in the ordinary course of business consistent with past

     accordance with its terms and in the ordinary course of business); (5)
     grant any increase in fees or other increases in compensation or other
     benefits to any of its present or former directors; or (6) effect any
     change in retirement benefits for any class of its Employees or officers

     opinion of counsel, is necessary or advisable to maintain the tax
     qualification of any plan under which the retirement benefits are
     provided); provided, however, that nothing in this Section 6.1 shall
     prevent Dime from renegotiating, amending or modifying the current

     each party hereto shall be permitted to take, or authorize or agree to
     take, any of the actions contemplated in such Sections without the consent
     of the other party, if such action (1) is reasonably necessary to qualify
     for, or preserve, an exemption of certain transactions from the operation
     of Section 16(b) of the Exchange Act in accordance with the provisions of
     SEC Rule 16b-3, as amended, or (2) is Previously Disclosed.

such dividends or distributions, and their corresponding record dates and
payment dates, are coordinated between the parties and are in the ordinary
course consistent with past practice and (2) such dividends or distributions are
not in amounts exceeding $0.25 per quarter in the case of Hudson and $0.06 per
quarter in the case of Dime, subject to and consistent with each party's normal

or advisable to consummate the transactions contemplated by this Agreement. Each
of Dime and Hudson shall have the right to review in advance, and to the extent
practicable each will consult with the other, in each case subject to applicable
laws relating to the exchange of information, with respect to all the
information relating to the other party, and any of their respective
subsidiaries, which appear in any filing made with, or written materials
submitted to, any third party or any Governmental Entity in connection with the
transactions contemplated by this Agreement. In exercising the foregoing right,
each of the parties hereto agrees to act reasonably and as promptly as

objectives stated in such joint business plan.

     6.6  Information Supplied.  Each of Hudson and Dime agrees, as to itself
and its subsidiaries, that none of the information supplied or to be supplied by
it for inclusion or incorporation by reference in (a) the Registration Statement
will, at the time the Registration Statement and each amendment and supplement
thereto, if any, become effective under the Securities Act, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading, and
(b) the Joint Proxy Statement and any amendment or supplement thereto will, at
the date of mailing to stockholders and at the times of the Dime Meeting and the
Hudson Meeting to be held in connection with this Agreement, contain any
statement which, in the light of the circumstances under which such statement is
made, will be false or misleading with respect to any material fact, or which
will omit to state any material fact necessary in order to make the statements
therein not false or misleading or necessary to correct any statement in any
earlier statement in the Joint Proxy Statement or any amendment or supplement
thereto. Neither the Joint Proxy Statement nor the Registration Statement shall

party in form and substance customary for "comfort" letters delivered by
independent accountants in connection with registration statements similar to
the Registration Statement.

     6.8  Access.  Upon reasonable notice, each party agrees to (and shall cause
each of its subsidiaries to) afford the other party's officers, employees,
counsel, accountants and other authorized representatives ("Representatives")
access, during normal business hours throughout the period until the Closing
Date, to its properties, books, contracts and records and, during such period,
shall (and shall cause each of its subsidiaries to) furnish promptly to the
other party all information concerning its business, properties and personnel as
may reasonably be requested; provided that no investigation pursuant to this
Section 6.8 shall affect or be deemed to modify any representation or warranty
made by the party furnishing such information. Each party will not, and will
cause its respective Representatives not to, use any information obtained
pursuant to this Section 6.8 for any purpose unrelated to the consummation of
the transactions contemplated by this Agreement. Subject to the requirements of
applicable law, pending consummation of the transactions herein contemplated,
each party conducting an investigation hereunder will keep confidential, and
will cause its Representatives to keep confidential, all information and
documents obtained from the other party pursuant to this Section 6.8 or during
the investigation leading up to the execution of this Agreement. The agreements
between Dime and Hudson regarding the confidentiality of such information in
effect at the date hereof (the "Confidentiality Agreements") shall continue and
survive in full force and effect until the Effective Time or, in the event this
Agreement is terminated, shall continue in accordance with the terms thereof.
Upon any termination of this Agreement, each party will collect and deliver to
the other party all nonpublic documents obtained by it or any of its
Representatives and then in their possession and any copies thereof and destroy
or cause to be destroyed all notes, memoranda or other documents in the
possession of it or of its Representatives containing or reflecting any
                                      A-20
<PAGE>   140

nonpublic information obtained from the other party, except to the extent that
any such information may be embodied in minutes of the meetings of such party's
Board of Directors or in filings, reports or submissions to or with any
Governmental Entity.

     6.9  Notification of Certain Matters.  Each of Dime and Hudson will give
prompt notice to the other of any fact, event or circumstance known to it that

cause or constitute a material breach of any of the representations, warranties,
covenants or agreements of such party contained herein or (c) is reasonably
likely to result in the failure of a condition to consummation set forth in
Article VII to be satisfied on or prior to June 30, 2000.

     6.10  Publicity.  The initial press release relating hereto will be a joint
press release and thereafter Hudson and Dime shall consult with each other prior
to issuing any press releases or otherwise making public statements with respect
to the transactions contemplated hereby and prior to making any filings with any
Governmental Entity or with the NYSE or the NASD with respect thereto.

     6.11  Benefit Plans.  (a) At or as promptly as practicable following the
Effective Time, the Surviving Corporation and its subsidiaries will adopt
employee benefit plans (including, without limitation, severance plans) covering
persons who become and remain employees of the Surviving Corporation or its
subsidiaries and who were immediately prior to the Effective Time employees of
Dime or its subsidiaries (the "Former Dime Employees") or employees of Hudson or
its subsidiaries (the "Former Hudson Employees") or will amend existing plans to
provide coverage for Former Dime Employees and Former Hudson Employees. It is
the express understanding and intention of the parties that no Former Dime
Employee or Former Hudson Employee or other person shall be deemed to be a third
party beneficiary, or have or acquire any right to enforce the provisions, of
this Section 6.11(a), and that nothing in this Agreement shall be deemed to
constitute a Plan or an amendment to a Plan.

     (b)  Each of Dime and Hudson agrees, with respect to any Pension Plans
maintained by them or any of their subsidiaries with respect to which the
"remedial amendment period" described in Revenue Procedure 99-23, 1999-16 I.R.B.
5 (4/19/99), and any subsequent pronouncement by the Internal Revenue Service
extending or modifying the remedial amendment period as so described, ends prior
to the Closing Date and with respect to any amendments to such plans required to
be adopted before the end of such remedial amendment period, that to the extent
a determination letter with respect to the qualification of such Pension Plan or
Plans under the Internal Revenue Code reflecting such amendments has not been
obtained, an application for such a letter shall be filed with the Internal
Revenue Service on or before the last day of such remedial amendment period.

     6.12  Expenses.  Each of the parties 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 or
other consultants, investment bankers, accountants and counsel, except that Dime

Statement and applications to Governmental Entities for the approval of the
Merger and (b) all listing, filing or registration fees, including, without
limitation, fees paid for filing the Registration Statement with the SEC and
fees paid for filings with Governmental Entities.

     6.13  Indemnification; Directors' and Officers' Insurance.  (a) Each of
Dime and Hudson agrees that, from and after the Effective Time, the Surviving
Corporation will indemnify and hold harmless each present and former director
and officer of Dime, Hudson and their respective subsidiaries, determined as of
the Effective Time (the "Indemnified Parties"), 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 or pertaining to matters
existing or occurring at or prior to the Effective Time, whether asserted or
claimed prior to, at or after the Effective Time, to the fullest extent that
Dime, Hudson or such subsidiary would have been permitted under applicable law
of the jurisdiction of its incorporation and the certificate of incorporation or
by-laws of Dime, Hudson or such subsidiary in effect
                                      A-21
<PAGE>   141

on the date hereof to indemnify such person (and the Surviving Corporation shall
also advance expenses as incurred to the fullest extent permitted under
applicable law; provided that the person to whom expenses are advanced provides
an undertaking to repay such advances if it is ultimately determined that such
person is not entitled to indemnification).

     (b)  To the extent that paragraph (a) shall not serve to indemnify and hold
harmless an Indemnified Party, for a period of six years after the Effective
Time, each of Dime and Hudson agrees that the Surviving Corporation shall,
subject to the terms set forth herein, indemnify and hold harmless, to the
fullest extent permitted under applicable law (and the Surviving Corporation
shall also advance expenses as incurred to the fullest extent permitted under
applicable law, provided that the person to whom expenses are advanced provides
an undertaking to repay such advances if it is ultimately determined that such
person is not entitled to indemnification), each Indemnified Party against any
Costs incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, arising
out of or pertaining to the transactions contemplated by this Agreement. In the
event any claim or claims are asserted or made within such six-year period, all
rights to indemnification in respect of any such claim or claims shall continue
until final disposition of any and all such claims.

     (c)  For a period of six years from the Effective Time, the Surviving
Corporation shall provide that portion of directors' and officers' liability
insurance that serves to reimburse the present and former officers and directors
of Hudson or any of its subsidiaries (determined as of the Effective Time) with
respect to claims against such directors and officers arising from facts or
events which occurred before the Effective Time, which insurance shall contain
at least the same coverage and amounts, and contain terms and conditions no less
advantageous, as that coverage currently provided by Hudson.

     (d)  Any Indemnified Party wishing to claim indemnification under Section
6.13(a) or (b), upon learning of any such claim, action, suit, proceeding or
investigation, shall promptly notify the Surviving Corporation thereof, but the
failure to so notify shall not relieve the Surviving Corporation of any
liability it may have to such Indemnified Party if such failure does not
materially prejudice the Surviving Corporation. In the event of any such claim,
action, suit, proceeding or investigation (whether arising before or after the
Effective Time), the Surviving Corporation shall have the right to assume the
defense thereof and the Surviving Corporation shall not be liable to such
Indemnified Parties for any legal expenses of other counsel or any other
expenses subsequently incurred by such Indemnified Parties in connection with
the defense thereof, except that, if the Surviving Corporation elects not to
assume such defense or counsel for the Indemnified Parties advises that there
are issues which raise conflicts of interest between the Surviving Corporation
and the Indemnified Parties, the Indemnified Parties may retain counsel
satisfactory to them, and the Surviving Corporation shall pay all reasonable
fees and expenses of such counsel for the Indemnified Parties promptly as
statements therefor are received. If such indemnity is not available with
respect to any Indemnified Party, then the Surviving Corporation and the
Indemnified Party shall contribute to the amount payable in such proportion as
is appropriate to reflect relative faults and benefits.

     6.14  Antitakeover Provisions.  If any "business combination",
"moratorium", "control share" or other state antitakeover statute or regulation
(collectively, "Antitakeover Provisions") may become applicable to the
transactions contemplated hereby, each of Dime and Hudson and the members of
their respective Boards of Directors will grant such approvals and take such
actions as are necessary so that the transactions contemplated by this Agreement
may be consummated as promptly as practicable on the terms contemplated hereby
and otherwise act to eliminate or minimize the effects of any Antitakeover
Provision on any of the transactions contemplated by this Agreement.

     6.15  Affiliate Agreements.  (a) As soon as practicable after the date
hereof, Dime shall identify to Hudson and Hudson shall identify to Dime all

paragraphs (c) and (d) of Rule 145 under the Securities Act and/or Accounting
Series Releases 130 and 135, as amended, of the SEC ("Affiliates"). Each of Dime
and Hudson shall use their best efforts to obtain a written agreement in the
form of Annex 4(a) (for Affiliates of Hudson) or 4(b) (for Affiliates of

                                      A-22
<PAGE>   142

Dime) from each person who is so identified as a possible Affiliate and shall
deliver copies of such written agreements to the other party as soon as
practicable.

     (b)  As soon as practicable after the date of the Dime Meeting or Hudson
Meeting, as applicable, Dime shall identify to Hudson and Hudson shall identify
to Dime all persons who were, at the time of the Dime Meeting or the Hudson
Meeting, possible Affiliates of Dime and Hudson, respectively, and who were not
previously identified in accordance with Section 6.15(a). Each of Dime and
Hudson shall use their best efforts to obtain a written agreement in the form of

efforts to cause to be listed on the NYSE, subject to official notice of
issuance, the shares of Surviving Corporation Common Stock to be issued in the
Merger.

this Agreement, each of Dime and Hudson agrees to use reasonable efforts to
take, or cause to be taken, all actions, and to do, or cause to be done, all
things necessary, proper or advisable to consummate and make effective, as soon
as practicable after the date of this Agreement, the transactions contemplated
hereby, including, without limitation, using reasonable efforts to lift or
rescind any injunction or restraining order or other order adversely affecting
the ability of the parties to consummate the transactions contemplated hereby.

     6.18  Reports.  Each of Dime and Hudson agrees to file, and to cause its
respective subsidiaries to file, all reports required to be filed with all
Governmental Entities pursuant to the Securities Laws or Federal or state
banking laws between the date of this Agreement and the Effective Time, and to
deliver to the other party copies of all such reports promptly after the same
are filed.

     6.19  Accounting and Tax Treatment.  Neither Dime nor Hudson will take,
cause or to the best of its ability permit to be taken any action that would
adversely affect the qualification of the Merger for pooling-of-interests
accounting treatment or the qualification of the Merger as a "reorganization"
within the meaning of Section 368 of the Internal Revenue Code; provided, that
nothing in this Section 6.19 shall preclude either party from exercising its
respective rights under the Stock Option Agreements.

     6.20  Assumptions.  The parties agree to take all reasonable action for the
Surviving Corporation to assume any guaranties or indentures to which Hudson is
currently a party, including, without limitation, guaranties and indentures
associated with the Hudson-guarantied mandatorily redeemable preferred capital
securities, Series B, of Hudson Capital Trust I and Hudson Capital Trust II
which hold solely junior subordinated debentures of Hudson.

     6.21  Bank Combination and Governance.  The parties agree to take all

the Subsidiary Bank is a New Jersey state-chartered commercial bank, (b) the
Board of Directors and senior executive officers of the Subsidiary Bank shall be
the same persons in the same positions as the Board of Directors and senior
executive officers of the Surviving Corporation and (c) the committees and
composition of committees of the Board of Directors of the Subsidiary Bank shall

a person, the term "subsidiary" means those corporations, banks, savings banks,
associations and other entities of which such person owns or controls 25% or
more of the outstanding equity securities either directly or through an unbroken
chain of entities as to each of which 25% or more of the outstanding equity
securities is owned directly or indirectly by its parent; provided however,
that, except for purposes of Section 5.3(q), there shall not be included any
such entity
                                      A-28
<PAGE>   148

to the extent that the equity securities of such entity were acquired in
satisfaction of a debt previously contracted in good faith or are owned or
controlled in a bona fide fiduciary capacity.

     (b)  Insofar as any provision of this Agreement shall require a subsidiary
to take or omit to take any action, such provision shall be deemed a covenant by
Dime or Hudson, as the case may be, to cause such action or omission to occur.

     9.9  Captions.  The Article, Section and paragraph captions herein are for
convenience of reference only, do not constitute part of this Agreement and

     9.10  Severability.  If any provision of this Agreement or the application
thereof to any person (including, without limitation, the officers and directors
of Dime and Hudson) or circumstance is determined by a court of competent
jurisdiction to be invalid, void or unenforceable, the remaining provisions
hereof, or the application of such provision to persons or circumstances other
than those as to which it has been held invalid or unenforceable, shall remain
in full force and effect and shall in no way be affected, impaired or
invalidated thereby, so long as the economic or legal substance of the
transactions contemplated hereby is not affected in any manner materially
adverse to any party. Upon such determination, the parties shall negotiate in
good faith in an effort to agree upon a suitable and equitable substitute
provision to effect the original intent of the parties. Prior to the termination
of this Agreement in accordance with its terms, the absence of adoption by the
stockholders of a party hereto shall not render invalid or inoperative any
provision hereof not required to be contained in the agreement of merger to be
adopted by such stockholders pursuant to Sections 251 and 252 of the DGCL, or
Section 14A: 10-3 of the NJBCA, as the case may be, and the certificate of

     Directorships (as defined below) to be equal (or as close to equal as
     possible) to the Ratio.

          (ii) The board of directors may decide, on the recommendation of both
     a Dime Nominating Committee (as defined below) and a Hudson Nominating
     Committee (as defined below), (A) not to designate any one or more
     directorships in the manner described in the previous paragraph (i), or (B)
     to determine that the Nominating Committee Procedures shall not apply to
     any one or more directorships.

          (iii) For any directorship occupied by, vacated by, to be occupied by,
     or designated for a Former Dime Director (a "Former Dime Directorship"),
     the Nominating Committee will consist of two Former Dime Directors and one

        Re:  Agreement and Plan of Merger between
             Dime Bancorp, Inc. and Hudson United Bancorp
            ----------------------------------------------------------------

Ladies and Gentlemen:

     I have been advised that I may be considered an "affiliate" of Hudson
United Bancorp (the "Company") for purposes of (i) Rule 145 of the General Rules
and Regulations (the "Rules and Regulations") of the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the
"Securities Act"), and/or (ii) SEC Accounting Series Releases 130 and 135, as
amended. Pursuant to the Agreement and Plan of Merger, dated as of the 15th day
of September, 1999 (the "Merger Agreement"), by and between the Company and Dime
Bancorp, Inc. ("Dime"), I may receive securities (the "Shares"), in exchange for
the shares of stock of the Company owned by me at the effective date of the
merger provided for in the Merger Agreement (the "Merger").

     I represent and warrant to, and agree with, the Company and Dime (for their
benefit and the benefit of the surviving corporation of the Merger) that:

          A.  I have carefully read this letter agreement and the Merger
     Agreement and have discussed their requirements and other applicable
     limitations upon my ability to sell, transfer or otherwise dispose of the
     Shares, to the extent I felt necessary, with my counsel or counsel for the
     Company.

          B.  I will not make any sale, transfer or other disposition of my
     Shares in violation of the Securities Act or the Rules and Regulations.

          C.  I have been advised that the offering, sale and delivery of the
     Shares to me in the Merger have been registered under the Securities Act on
     a Registration Statement on Form S-4. I have also been advised, however,
     that, since I may be considered an "affiliate" of the Company at the time
     the Merger Agreement is submitted for a vote of the stockholders of the
     Company, any public offering or sale by me of any of the Shares will, under
     current law, require either (i) the further registration under the
     Securities Act of the Shares to be offered and sold, (ii) compliance by me
     with SEC Rule 145 under the Securities Act in connection with such offer
     and sale or (iii) the availability of another exemption from registration
     of such Shares under the Securities Act for such offer and sale.

          D.  I have been informed by the Company that the Shares have not been
     registered under the Securities Act for distribution by me and that the
     Shares must be held by me unless (i) such Shares have been registered for
     distribution under the Securities Act, (ii) a sale of the Shares is made in
     conformity with the volume and other limitations of SEC Rule 145 under the
     Securities Act or (iii) in the opinion of counsel reasonably acceptable to
     the surviving corporation, some other exemption from registration under the
     Securities Act is available with respect to any such proposed sale,
     transfer or other disposition of the Shares.
<PAGE>   156
Dime Bancorp, Inc.
Hudson United Bancorp

          E.  I understand that the surviving corporation is under no obligation
     to register the sale, transfer or other disposition of the Shares by me or
     on my behalf under the Securities Act or to take any other action necessary
     in order to make compliance with an exemption from such registration
     available to me.

          F.  I also understand that stop transfer instructions will be given to
     all transfer agents for the Shares and that there will be placed on the
     certificates for the Shares issued to me, or any replacements or
     substitutes therefor, a legend stating in substance:

             "The shares represented by this certificate were issued in a
        transaction to which Rule 145 under the Securities Act of 1933 applies.
        The shares represented by this certificate may only be transferred in
        accordance with the terms of an agreement, dated [            ], 1999,
        between the registered holder hereof and the issuer, a copy of which
        agreement will be mailed to the holder hereof without charge promptly
        after receipt by the issuer of a written request therefor."

     It is understood and agreed that the legend set forth in paragraph F above
shall be removed by the delivery of substitute certificates without such legend
if I shall have delivered to the surviving corporation (1) a copy of a letter
from the staff of the SEC, or an opinion of counsel in form and substance
reasonably satisfactory to the surviving corporation, to the effect that such
legend is not required for purposes of the Act or (2) evidence or
representations satisfactory to the surviving corporation that the Shares
represented by such certificate are being or have been sold in conformity with
the provisions of Rule 145(d).

     I further represent to and covenant with each of the Company and Dime (for
their benefit and the benefit of the surviving corporation) that (1) I will not,
within the 30 days prior to the Closing Date (as defined in the Merger
Agreement), sell, transfer or otherwise dispose of any shares of stock of the
Company and (2) I will not sell, transfer or otherwise dispose of any Shares
(whether or not acquired by me in the Merger) until after such time as results
covering at least 30 days of combined operations of the Company and Dime have
been published by the surviving corporation, in the form of a quarterly earnings
report, an effective registration statement filed with the SEC, a report filed
with the SEC on Form 10-K, 10-Q or 8-K or any other public filing or
announcement that includes such combined results of operations. Furthermore, I
understand that the Company and the surviving corporation will give stop
transfer instructions to their respective transfer agents in order to prevent
the breach of the covenants made by me in this paragraph. I also understand that
the Merger is intended to be treated for accounting purposes as a
"pooling-of-interests", and I agree that, if the Company or the surviving
corporation advises me in writing that additional restrictions apply to my
ability to sell, transfer or otherwise dispose of stock of the Company or Shares
in order to be entitled to use the pooling of interests accounting method, I
will abide by such restrictions.

     I further understand and agree that this letter agreement shall apply to
all shares of the stock of the Company and all of the Shares that I am deemed to
beneficially own pursuant to applicable federal securities laws.

     By its acceptance hereof, Dime Bancorp, Inc. agrees, for a period of two
years after the effective date of the Merger, that it, as the surviving
corporation, will file on a timely basis all reports required to be filed by it
pursuant to Section 13 of the Securities Exchange Act of 1934, as amended, so
that the public information provisions of SEC Rule 144(c) under the Securities
Act are satisfied and the resale provisions of SEC Rules 145(d)(1) and (2) are
therefore available to me in the event I desire to transfer any Shares issued to
me in the Merger.

Ladies and Gentlemen:

     STOCK OPTION AGREEMENT, dated as of September 16, 1999 (this "Agreement"),
between Hudson United Bancorp, a New Jersey corporation ("Grantee"), and Dime
Bancorp, Inc., a Delaware corporation ("Issuer").

                                    RECITALS

     A.  Merger Agreement.  Grantee and Issuer have entered into an Agreement
and Plan of Merger, dated as of September 15, 1999 (the "Merger Agreement"),
which agreement was executed and delivered on the day preceding the date of this
Stock Option Agreement, pursuant to which Grantee is to merge with and into
Issuer (the "Merger"); and

     B.  Option.  As a condition to Grantee's entering into the Merger Agreement
and in consideration therefor, Issuer has agreed to grant Grantee the Option (as
hereinafter defined).

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein and in the Merger Agreement, the parties hereto
agree as follows:

          1.  Grant of Option.  (a) Issuer hereby grants to Grantee an
     unconditional, irrevocable option (the "Option") to purchase, subject to
     the terms hereof, up to an aggregate of 22,271,682 fully paid and
     nonassessable shares of the common stock, par value $0.01 per share, of
     Issuer ("Common Stock") at a price per share equal to $17 3/4; provided,
     however, that in no event shall the number of shares for which this Option
     is exercisable exceed 19.9% of the issued and outstanding shares of Common
     Stock. The number of shares of Common Stock that may be received upon the
     exercise of the Option and the Option Price are subject to adjustment as
     herein set forth.

          (b) In the event that any additional shares of Common Stock are issued
     or otherwise become outstanding after the date of this Agreement (other
     than pursuant to this Agreement and other than pursuant to an event
     described in Section 5(a) hereof), the number of shares of Common Stock
     subject to the Option shall be increased so that, after such issuance, such
     number together with any shares of Common Stock previously issued pursuant
     hereto, equals 19.9% of the number of shares of Common Stock then issued
     and outstanding without giving effect to any shares subject or issued
     pursuant to the Option. Nothing contained in this Section l(b) or elsewhere
     in this Agreement shall be deemed to authorize Issuer to issue shares in
     breach of any provision of the Merger Agreement.

          2.  Exercise.  (a) The Holder (as hereinafter defined) may exercise
     the Option, in whole or part, if, but only if, both an Initial Triggering
     Event (as hereinafter defined) and a Subsequent Triggering Event (as
     hereinafter defined) shall have occurred prior to the occurrence of an
     Exercise Termination Event (as hereinafter defined), provided that the
     Holder shall have sent the written notice of such exercise (as provided in
     subsection (e) of this Section 2) within six (6) months following such
     Subsequent Triggering Event (or such later period as provided in Section
     10). Each of the following shall be an Exercise Termination Event: (i) the
     Effective Time (as defined in the Merger Agreement) of the Merger; (ii)
     termination of the Merger Agreement in accordance with the provisions
     thereof if such termination occurs prior to the occurrence of an Initial
     Triggering Event except a termination by Grantee pursuant to Section 8.3(a)
     of the Merger Agreement (unless the breach by Issuer giving rise to such
     right of termination is non-volitional) (a "Listed Termination"); or (iii)
     the passage of eighteen (18) months (or such longer period as provided in
     Section 10) after termination of the Merger Agreement if such termination
     follows the occurrence of an Initial Triggering Event or is a Listed
     Termination. The term "Holder" shall mean the holder or holders of the
     Option. Notwithstanding anything to the contrary contained herein, the
     Option may not be exercised at any time when Grantee shall be in material
     breach of any of its covenants or agreements contained in the Merger
     Agreement such that Issuer shall be entitled to terminate the Merger
     Agreement pursuant to Section 8.4(a) thereof.

          (b) The term "Initial Triggering Event" shall mean any of the
     following events or transactions occurring on or after the date hereof:

             (i) Issuer or any of its Significant Subsidiaries (as defined in
        Rule 1-02 of Regulation S-X promulgated by the Securities and Exchange
        Commission (the "SEC")) (the "Issuer Subsidiaries"), without having
        received Grantee's prior written consent, shall have entered into an
        agreement to engage in an Acquisition Transaction (as hereinafter
        defined) 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 Securities Exchange Act of 1934, as amended (the "1934
        Act"), and the rules and regulations thereunder) other than Grantee or
        any of its Subsidiaries (each a "Grantee Subsidiary") or the Board of
        Directors of Issuer (the "Issuer Board") shall have recommended that the
        stockholders of Issuer approve or accept any Acquisition Transaction
        other than as contemplated by the Merger Agreement. For purposes of this
        Agreement, (a)"Acquisition Transaction" shall mean (x) a merger or
        consolidation, or any similar transaction, involving Issuer or any
        Issuer Subsidiary (other than mergers, consolidations or similar
        transactions involving solely Issuer and/or one or more wholly-owned
        Subsidiaries of the Issuer, provided, any such transaction is not
        entered into in violation of the terms of the Merger Agreement), (y) a
        purchase, lease or other acquisition of all or any substantial part of
        the assets or deposits of Issuer or any Issuer Subsidiary, or (z) a
        purchase or other acquisition (including by way of merger,
        consolidation, share exchange or otherwise) of securities representing
        10% or more of the voting power of Issuer or any Issuer Subsidiary and
        (b) "Subsidiary" shall have the meaning set forth in Rule 12b-2 under
        the 1934 Act;

             (ii) Any person other than the Grantee or any Grantee Subsidiary
        shall have acquired beneficial ownership or the right to acquire
        beneficial ownership of 10% or more of the outstanding shares of Common
        Stock (the term "beneficial ownership" for purposes of this Agreement
        having the meaning assigned thereto in Section 13(d) of the 1934 Act,
        and the rules and regulations thereunder);

             (iii) The stockholders of Issuer shall have voted and failed to
        approve the Merger Agreement and the Merger at a meeting which has been
        held for that purpose or any adjournment or postponement thereof, or
        such meeting shall not have been held in violation of the Merger
        Agreement or shall have been canceled prior to termination of the Merger
        Agreement if, prior to such meeting (or if such meeting shall not have
        been held or shall have been canceled, prior to such termination), it
        shall have been publicly announced that any person (other than Grantee
        or any of its Subsidiaries) shall have made, or disclosed an intention
        to make, a proposal to engage in an Acquisition Transaction;

             (iv) The Issuer Board shall have withdrawn, modified or qualified
        (or publicly announced its intention to withdraw, modify or qualify) in
        any manner adverse in any respect to Grantee its recommendation that the
        stockholders of Issuer approve the transactions contemplated by the
        Merger Agreement in anticipation of engaging in an Acquisition
        Transaction, or Issuer or any Issuer Subsidiary shall have authorized,
        recommended, proposed (or publicly announced its intention to authorize,
        recommend or propose) an agreement to engage in an Acquisition
        Transaction with any person other than Grantee or a Grantee Subsidiary;

             (v) Any person other than Grantee or any Grantee Subsidiary shall
        have filed with the SEC a registration statement or tender offer
        materials with respect to a potential exchange or tender offer that
        would constitute an Acquisition Transaction (or filed a preliminary
        proxy statement with the SEC with respect to a potential vote by its
        stockholders to approve the issuance of shares to be offered in such an
        exchange offer);

             (vi) Issuer shall have willfully breached any covenant or
        obligation contained in the Merger Agreement after an overture is made
        by a third party to Issuer or its stockholders to engage in an
        Acquisition Transaction, and (a) following such breach Grantee would be
        entitled to terminate the Merger Agreement (whether immediately or after
        the giving of notice or passage of time or

                                       B-2
<PAGE>   163

        both) and (b) such breach shall not have been cured prior to the Notice
        Date (as defined in Section 2(e)); or

             (vii) Any person other than Grantee or any Grantee Subsidiary,
        without Grantee's prior written consent, shall have filed an application
        or notice with the Board of Governors of the Federal Reserve System (the
        "Federal Reserve Board"), the Office of Thrift Supervision (the "OTS")
        or other federal or state bank regulatory or antitrust authority, which
        application or notice has been accepted for processing, for approval to
        engage in an Acquisition Transaction.

          (c) The term "Subsequent Triggering Event" shall mean any of the
     following events or transactions occurring after the date hereof:

             (i) The acquisition by any person (other than Grantee or any
        Grantee Subsidiary) of beneficial ownership of 25% or more of the then
        outstanding Common Stock; or

             (ii) The occurrence of the Initial Triggering Event described in
        clause (i) of subsection (b) of this Section 2, except that the
        percentage referred to in clause (z) of the second sentence thereof
        shall be 25%.

          (d) Issuer shall notify Grantee promptly in writing of the occurrence
     of any Initial Triggering Event or Subsequent Triggering Event (together, a
     "Triggering Event"), it being understood that the giving of such notice by
     Issuer shall not be a condition to the right of the Holder to exercise the
     Option.

          (e) In the event the Holder is entitled to and wishes to exercise the
     Option (or any portion thereof), it shall send to Issuer a written notice
     (the date of which being herein referred to as the "Notice Date")
     specifying (i) the total number of shares it will purchase pursuant to such
     exercise and (ii) a place and date not earlier than three business days nor
     later than 60 business days from the Notice Date for the closing of such
     purchase (the "Closing Date"); provided, that if prior notification to or
     approval of the Federal Reserve Board or any other regulatory or antitrust
     agency is required in connection with such purchase, the Holder shall
     promptly file the required notice or application for approval, shall
     promptly notify Issuer of such filing and shall expeditiously process the
     same and the period of time that otherwise would run pursuant to this
     sentence shall run instead from the date on which any required notification
     periods have expired or been terminated or such approvals have been
     obtained and any requisite waiting period or periods shall have passed. Any
     exercise of the Option shall be deemed to occur on the Notice Date relating
     thereto.

          (f) At the closing referred to in subsection (e) of this Section 2,
     the Holder shall (i) pay to Issuer the aggregate purchase price for the
     shares of Common Stock purchased pursuant to the exercise of the Option in
     immediately available funds by wire transfer to a bank account designated
     by Issuer and (ii) present and surrender this Agreement to Issuer at its
     principal executive offices, provided that the failure or refusal of the
     Issuer to designate such a bank account or accept surrender of this
     Agreement shall not preclude the Holder from exercising the Option.

          (g) At such closing, simultaneously with the delivery of immediately
     available funds as provided in subsection (f) of this Section 2, Issuer
     shall deliver to the Holder a certificate or certificates representing the
     number of shares of Common Stock purchased by the Holder and, if the Option
     should be exercised in part only, a new Option evidencing the rights of the
     Holder thereof to purchase the balance of the shares purchasable hereunder.

          (h) Certificates for Common Stock delivered at a closing hereunder may
     be endorsed with a restrictive legend that shall read substantially as
     follows:

             "The transfer of the shares represented by this certificate is
        subject to certain provisions of an agreement between the registered
        holder hereof and Issuer and to resale restrictions arising under the
        Securities Act of 1933, as amended. A copy of such agreement is on file
        at the principal office of Issuer and will be provided to the holder
        hereof without charge upon receipt by Issuer of a written request
        therefor."

                                       B-3
<PAGE>   164

     It is understood and agreed that: (i) the reference to the resale
     restrictions of the Securities Act of 1933, as amended (the "1933 Act") in
     the above legend shall be removed by delivery of substitute certificate(s)
     without such reference if the Holder shall have delivered to Issuer a copy
     of a letter from the staff of the SEC, or an opinion of counsel, in form
     and substance reasonably satisfactory to Issuer, to the effect that such
     legend is not required for purposes of the 1933 Act; (ii) the reference to
     the provisions of this Agreement in the above legend shall be removed by
     delivery of substitute certificate(s) without such reference if the shares
     have been sold or transferred in compliance with the provisions of this
     Agreement and under circumstances that do not require the retention of such
     reference in the opinion of counsel to the Holder, in form and substance
     reasonably satisfactory to the Issuer; and (iii) the legend shall be
     removed in its entirety if the conditions in the preceding clauses (i) and
     (ii) are both satisfied. In addition, such certificates shall bear any
     other legend as may be required by law.

          (i) Upon the giving by the Holder to Issuer of the written notice of
     exercise of the Option provided for under subsection (e) of this Section 2
     and the tender of the applicable purchase price in immediately available
     funds, the Holder shall be deemed to be the holder of record of the shares
     of 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 Common Stock shall not then be actually
     delivered to the 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, issue and delivery of stock
     certificates under this Section 2 in the name of the Holder or its
     assignee, transferee or designee.

          3.  Covenants of Issuer.  Issuer agrees: (i) that it shall at all
     times maintain, free from preemptive rights, sufficient authorized but
     unissued or treasury shares of Common Stock so that the Option may be
     exercised without additional authorization of Common Stock after giving
     effect to all other options, warrants, convertible securities and other
     rights to purchase 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 (x)
     complying with all applicable premerger notification, reporting and waiting
     period requirements specified in 15 U.S.C. Section 18a and regulations
     promulgated thereunder and (y) in the event, under the Bank Holding Company
     Act of 1956, as amended (the "BHCA"), the Home Owners' Loan Act, as amended
     (the "HOLA") or the Change in Bank Control Act of 1978, as amended, or any
     state or other federal banking law, prior approval of or notice to the
     Federal Reserve Board, the OTS or to any state or other federal regulatory
     authority is necessary before the Option may be exercised, cooperating
     fully with the Holder in preparing such applications or notices and
     providing such information to the Federal Reserve Board, the OTS or such
     state or other federal regulatory authority as they may require) in order
     to permit the Holder to exercise the Option and Issuer duly and effectively
     to issue shares of Common Stock pursuant hereto; and (iv) promptly to take
     all action provided herein to protect the rights of the Holder against
     dilution.

          4.  Exchange.  This Agreement (and the Option granted hereby) are
     exchangeable, without expense, at the option of the 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, on the same terms
     and subject to the same conditions as are set forth herein, in the
     aggregate the same number of shares of Common Stock purchasable hereunder.
     The terms "Agreement" and "Option" as used herein include any 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

                                       B-4
<PAGE>   165

     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.

          5.  Certain Adjustments.  In addition to the adjustment in the number
     of shares of Common Stock that are purchasable upon exercise of the Option
     pursuant to Section 1 of this Agreement, the number of shares of Common
     Stock purchasable upon the exercise of the Option and the Option Price
     shall be subject to adjustment from time to time as provided in this
     Section 5. In the event of any change in Common Stock by reason of a stock
     dividend, stock split, split-up, recapitalization, stock combination,
     exchange of shares or similar transaction, the type and number of shares or
     securities subject to the Option, and the Option Price therefor, shall be
     adjusted appropriately, and proper provision shall be made in the
     agreements governing such transaction so that Grantee shall receive, upon
     exercise of the Option, the number and class of shares or other securities
     or property that Grantee would have received in respect of 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 Common
     Stock are issued after the date of this Agreement (other than pursuant to
     an event described in the first sentence of this Section 5), the number of
     shares of Common Stock subject to the Option shall be adjusted so that,
     after such issuance, it, together with any shares of Common Stock
     previously issued pursuant hereto, equals 19.9% of the number of shares of
     Common Stock then issued and outstanding, without giving effect to any
     shares subject to or issued pursuant to the Option.

          6.  Registration Rights.  Upon the occurrence of a Subsequent
     Triggering Event that occurs prior to an Exercise Termination Event, Issuer
     shall, at the request of Grantee delivered within twelve (12) months (or
     such later period as provided in Section 10) of such Subsequent Triggering
     Event (whether on its own behalf or on behalf of any subsequent holder of
     this Option (or part thereof) or any of the shares of Common Stock issued
     pursuant hereto), promptly prepare, file and keep current a registration
     statement under the 1933 Act covering any shares issued and issuable
     pursuant to this Option and shall use its reasonable best efforts to cause
     such registration statement to become effective and remain current in order
     to permit the sale or other disposition of any shares of Common Stock
     issued upon total or partial exercise of this Option ("Option Shares") in
     accordance with any plan of disposition requested by Grantee. Issuer will
     use its reasonable best efforts to cause such registration statement
     promptly to become effective and then to remain effective for such period
     not in excess of 180 days from the day such registration statement first
     becomes effective or such shorter time as may be reasonably necessary to
     effect such sales or other dispositions. Grantee shall have the right to
     demand two such registrations. The Issuer shall bear the costs of such
     registrations (including, but not limited to, Issuer's attorneys' fees,
     printing costs and filing fees, except for underwriting discounts or
     commissions, brokers' fees and the fees and disbursements of Grantee's
     counsel related thereto). The foregoing notwithstanding, if, at the time of
     any request by Grantee for registration of Option Shares as provided above,
     Issuer is in registration with respect to an underwritten public offering
     by Issuer of shares of Common Stock, and if in the good faith judgment of
     the managing underwriter or managing underwriters, or, if none, the sole
     underwriter or underwriters, of such offering the offer and sale of the
     Option Shares would interfere with the successful marketing of the shares
     of Common Stock offered by Issuer, the number of Option Shares otherwise to
     be covered in the registration statement contemplated hereby may be
     reduced; provided, however, that after any such required reduction the
     number of Option Shares to be included in such offering for the account of
     the Holder shall constitute at least 33 1/3% of the total number of shares
     to be sold by the Holder and Issuer in the aggregate; and provided further,
     however, that if such reduction occurs, then Issuer shall file a
     registration statement for the balance as promptly as practicable
     thereafter as to which no reduction pursuant to this Section 6 shall be
     permitted or occur and the Holder shall thereafter be entitled to one
     additional registration and the twelve (12) month period referred to in the
     first sentence of this section shall be increased to twenty-four (24)
     months. Each such Holder shall provide all information reasonably requested
     by Issuer for inclusion in any registration statement to be filed
     hereunder. If requested by any such Holder in connection with such
     registration, Issuer shall become a party to any underwriting agreement
     relating to the sale of such

                                       B-5
<PAGE>   166

     shares, but only to the extent of obligating itself in respect of
     representations, warranties, indemnities and other agreements customarily
     included in such underwriting agreements for Issuer. Upon receiving any
     request under this Section 6 from any Holder, Issuer agrees to send a copy
     thereof to any other person known to Issuer to be entitled to registration
     rights under this Section 6, in each case by promptly mailing the same,
     postage prepaid, to the address of record of the persons entitled to
     receive such copies. Notwithstanding anything to the contrary contained
     herein, in no event shall the number of registrations that Issuer is
     obligated to effect be increased by reason of the fact that there shall be
     more than one Holder as a result of any assignment or division of this
     Agreement.

          7.  Repurchase.  (a) At any time after the occurrence of a Repurchase
     Event (as defined below) (i) at the request of the Holder, delivered prior
     to an Exercise Termination Event (or such later period as provided in
     Section 10), Issuer (or any successor thereto) shall repurchase the Option
     from the Holder at a price (the "Option Repurchase Price") equal to the
     amount by which (A) the market/offer price (as defined below) exceeds (B)
     the Option Price, multiplied by the number of shares for which this Option
     may then be exercised and (ii) at the request of the owner of Option Shares
     from time to time (the "Owner"), delivered prior to an Exercise Termination
     Event (or such later period as provided in Section 10), Issuer (or any
     successor thereto) shall repurchase such number of the Option Shares from
     the Owner as the Owner shall designate at a price (the "Option Share
     Repurchase Price") equal to the market/offer price multiplied by the number
     of Option Shares so designated. The term "market/offer price" shall mean
     the highest of (i) the price per share of Common Stock at which a tender or
     exchange offer therefor has been made, (ii) the price per share of Common
     Stock to be paid by any third party pursuant to an agreement with Issuer,
     (iii) the highest closing price for shares of Common Stock within the
     six-month period immediately preceding the date the Holder gives notice of
     the required repurchase of this Option or the Owner gives notice of the
     required repurchase of Option Shares, as the case may be, or (iv) in the
     event of a sale of all or any substantial part of Issuer's assets or
     deposits, the sum of the net price paid in such sale for such assets or
     deposits and the current market value of the remaining net assets of Issuer
     as determined by a nationally recognized investment banking firm selected
     by the Holder or the Owner, as the case may be, and reasonably acceptable
     to Issuer, divided by the number of shares of Common Stock of Issuer
     outstanding at the time of such sale. In determining the market/offer
     price, the value of consideration other than cash shall be determined by a
     nationally recognized investment banking firm selected by the Holder or
     Owner, as the case may be, and reasonably acceptable to Issuer.

          (b) The Holder and the Owner, as the case may be, may exercise its
     right to require Issuer to repurchase the Option and any Option Shares
     pursuant to this Section 7 by surrendering for such purpose to Issuer, at
     its principal office, a copy of this Agreement or certificates for Option
     Shares, as applicable, accompanied by a written notice or notices stating
     that the Holder or the Owner, as the case may be, elects to require Issuer
     to repurchase this Option and/or the Option Shares in accordance with the
     provisions of this Section 7. The Holder shall also represent and warrant
     that it has sole record and beneficial ownership of such Option Shares and
     that such Option Shares are then free and clear of all liens. As promptly
     as practicable, and in any event within five (5) business days after the
     surrender of the Option and/or certificates representing Option Shares and
     the receipt of such notice or notices relating thereto, Issuer shall
     deliver or cause to be delivered to the Holder the Option Repurchase Price
     and/or to the Owner the Option Share Repurchase Price therefor or the
     portion thereof that Issuer is not then prohibited under applicable law and
     regulation from so delivering.

          (c) To the extent that Issuer is prohibited under applicable law or
     regulation, or as a consequence of administrative policy, from repurchasing
     the Option and/or the Option Shares in full, Issuer shall immediately so
     notify the Holder and/or the Owner and thereafter deliver or cause to be
     delivered, from time to time, to the Holder and/or the Owner, as
     appropriate, the portion of the Option Repurchase Price and the Option
     Share Repurchase Price, respectively, that it is no longer prohibited from
     delivering, within five (5) business days after the date on which Issuer is
     no longer so prohibited; provided, however, that if Issuer at any time
     after delivery of a notice of repurchase

                                       B-6
<PAGE>   167

     pursuant to paragraph (b) of this Section 7 is prohibited under applicable
     law or regulation, or as a consequence of administrative policy, from
     delivering to the Holder and/or the Owner, as appropriate, the Option
     Repurchase Price and the Option Share Repurchase Price, respectively, in
     full (and Issuer hereby undertakes to use its reasonable best efforts to
     obtain all required regulatory and legal approvals and to file any required
     notices as promptly as practicable in order to accomplish such repurchase),
     the Holder or Owner may revoke its notice of repurchase of the Option
     and/or the Option Shares whether in whole or to the extent of the
     prohibition, whereupon, in the latter case, Issuer shall promptly (i)
     deliver to the Holder and/or the Owner, as appropriate, that portion of the
     Option Repurchase Price and/or the Option Share Repurchase Price that
     Issuer is not prohibited from delivering; and (ii) deliver, as appropriate,
     either (A) to the Holder, a new Agreement evidencing the right of the
     Holder to purchase that number of shares of Common Stock obtained by
     multiplying the number of shares of Common Stock for which the surrendered
     Agreement was exercisable at the time of delivery of the notice of
     repurchase by a fraction, the numerator of which is the Option Repurchase
     Price less the portion thereof theretofore delivered to the Holder and the
     denominator of which is the Option Repurchase Price, and/or (B) to the
     Owner, a certificate for the Option Shares it is then so prohibited from
     repurchasing. If an Exercise Termination Event shall have occurred prior to
     the date of the notice by Issuer described in the first sentence of this
     subsection (c), or shall be scheduled to occur at any time before the
     expiration of a period ending on the thirtieth day after such date, the
     Holder shall nonetheless have the right to exercise the Option until the
     expiration of such 30-day period.

          (d) For purposes of this Section 7, a "Repurchase Event" shall be
     deemed to have occurred upon the occurrence of any of the following events
     or transactions after the date hereof:

             (i) the acquisition by any person (other than Grantee or any
        Grantee Subsidiary) of beneficial ownership of 50% or more of the then
        outstanding Common Stock; or

             (ii) the consummation of any Acquisition Transaction described in
        Section 2(b)(i) hereof, except that the percentage referred to in clause
        (z) shall be 25%.

          8.  Substitute Option.  (a) In the event that prior to an Exercise
     Termination Event, Issuer shall enter into an agreement (i) to consolidate
     with or merge into any person, other than Grantee or a Grantee Subsidiary,
     or engage in a plan of exchange with any person, other than Grantee or a
     Grantee Subsidiary and Issuer shall not be the continuing or surviving
     corporation of such consolidation or merger or the acquirer in such plan of
     exchange, (ii) to permit any person, other than Grantee or a Grantee
     Subsidiary, to merge into Issuer or be acquired by Issuer in a plan of
     exchange and Issuer shall be the continuing or surviving or acquiring
     corporation, but, in connection with such merger or plan of exchange, the
     then outstanding shares of Common Stock shall be changed into or exchanged
     for stock or other securities of any other person or cash or any other
     property or the then outstanding shares of Common Stock shall after such
     merger or plan of exchange represent less than 50% of the outstanding
     shares and share equivalents of the merged or acquiring company, or (iii)
     to sell or otherwise transfer all or a substantial part of its or any
     Issuer Subsidiary's assets or deposits to any person, other than Grantee or
     a Grantee Subsidiary, then, and in each such case, the agreement governing
     such transaction shall make proper provision 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 the Holder, of either (x) the
     Acquiring Corporation (as hereinafter defined) or (y) any person that
     controls the Acquiring Corporation.

          (b) The following terms have the meanings indicated:

             (i) "Acquiring Corporation" shall mean (i) the continuing or
        surviving person of a consolidation or merger with Issuer (if other than
        Issuer), (ii) the acquiring person in a plan of exchange in which Issuer
        is acquired, (iii) the Issuer in a merger or plan of exchange in which
        Issuer is the continuing or surviving or acquiring person and (iv) the
        transferee of all or a substantial part of Issuer's assets or deposits
        (or the assets or deposits of any Issuer Subsidiary).

                                       B-7
<PAGE>   168

             (ii) "Substitute Common Stock" shall mean the common stock issued
        by the issuer of the Substitute Option upon exercise of the Substitute
        Option.

             (iii) "Assigned Value" shall mean the market/offer price, as
        defined in Section 7.

             (iv) "Average Price" shall mean the average closing price of a
        share of the Substitute Common Stock for one (1) 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 the
        person merging into Issuer or by any company which controls or is
        controlled by such person, as the Holder may elect.

          (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 the Holder. The issuer of the
     Substitute Option shall also enter into an agreement with the then Holder
     or Holders of the Substitute Option in substantially the same form as this
     Agreement (after giving effect for such purpose to the provisions of
     Section 9), which agreement shall be applicable to the Substitute Option.

          (d) The Substitute Option shall be exercisable for such number of
     shares of Substitute Common Stock as is equal to the Assigned Value
     multiplied by the number of shares of Common Stock for which the Option was
     exercisable immediately prior to the event described in the first sentence
     of Section 8(a), divided by the Average Price. The exercise price of the
     Substitute Option per share of Substitute Common Stock shall then be equal
     to the Option Price multiplied by a fraction, the numerator of which shall
     be the number of shares of Common Stock for which the Option was
     exercisable immediately prior to the event described in the first sentence
     of Section 8(a) and the denominator of which shall be the number of shares
     of Substitute Common Stock for which the Substitute Option is exercisable.

          (e) In no event, pursuant to any of the foregoing paragraphs, shall
     the Substitute Option be exercisable for more than 19.9% 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 shares of Substitute Common Stock outstanding prior
     to exercise but for this clause (e), the issuer of the Substitute Option
     (the "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 this clause (e) over (ii) the value of the
     Substitute Option after giving effect to the limitation in this clause (e).
     This difference in value shall be determined by a nationally recognized
     investment banking firm selected by the Holder.

          (f) Issuer shall not enter into any transaction described in
     subsection (a) of this Section 8 unless the Acquiring Corporation and any
     person that controls the Acquiring Corporation assume in writing all the
     obligations of Issuer hereunder.

          9.  Repurchase of Substitute Option.  (a) At the request of the holder
     of the Substitute Option (the "Substitute Option Holder"), the Substitute
     Option Issuer shall repurchase the Substitute Option from the Substitute
     Option Holder at a price (the "Substitute Option Repurchase Price") equal
     to the amount by which (i) the Highest Closing Price (as hereinafter
     defined) exceeds (ii) the exercise price of the Substitute Option,
     multiplied by the number of shares of Substitute Common Stock for which the
     Substitute Option may then be exercised, and at the request of the owner
     (the "Substitute Share Owner") of shares of Substitute Common Stock (the
     "Substitute Shares"), the Substitute Option Issuer shall repurchase the
     Substitute Shares at a price (the "Substitute Share Repurchase Price")
     equal to the Highest Closing Price multiplied by the number of Substitute
     Shares so designated. The term "Highest Closing Price" shall mean the
     highest closing price for shares of Substitute Common Stock within the
     six-month period immediately preceding the date the Substitute

                                       B-8
<PAGE>   169

     Option Holder gives notice of the required repurchase of the Substitute
     Option or the Substitute Share Owner gives notice of the required
     repurchase of the Substitute Shares, as applicable.

          (b) The Substitute Option Holder and the Substitute Share Owner, as
     the case may be, may exercise its respective rights to require the
     Substitute Option Issuer to repurchase the Substitute Option and the
     Substitute Shares pursuant to this Section 9 by surrendering for such
     purpose to the Substitute Option Issuer, at its principal office, the
     agreement for such Substitute Option (or, in the absence of such an
     agreement, a copy of this Agreement) and/or certificates for Substitute
     Shares accompanied by a written notice or notices stating that the
     Substitute Option Holder or the Substitute Share Owner, as the case may be,
     elects to require the Substitute Option Issuer to repurchase the Substitute
     Option and/or the Substitute Shares in accordance with the provisions of
     this Section 9. As promptly as practicable and in any event within five (5)
     business days after the surrender of the Substitute Option and/or
     certificates representing Substitute Shares and the receipt of such notice
     or notices relating thereto, the Substitute Option Issuer shall deliver or
     cause to be delivered to the Substitute Option Holder the Substitute Option
     Repurchase Price and/or to the Substitute Share Owner the Substitute Share
     Repurchase Price therefor or the portion thereof which the Substitute
     Option Issuer is not then prohibited under applicable law and regulation
     from so delivering.

          (c) To the extent that the Substitute Option Issuer is prohibited
     under applicable law or regulation, or as a consequence of administrative
     policy, from repurchasing the Substitute Option and/ or the Substitute
     Shares in part or in full, the Substitute Option Issuer shall immediately
     so notify the Substitute Option Holder and/or the Substitute Share Owner
     and thereafter deliver or cause to be delivered, from time to time, to the
     Substitute Option Holder and/or the Substitute Share Owner, as appropriate,
     the portion of the Substitute Option Repurchase Price and/or the Substitute
     Share Repurchase Price, respectively, which it is no longer prohibited from
     delivering, within five (5) business days after the date on which the
     Substitute Option Issuer is no longer so prohibited; provided, however,
     that if the Substitute Option Issuer is at any time after delivery of a
     notice of repurchase pursuant to subsection (b) of this Section 9
     prohibited under applicable law or regulation, or as a consequence of
     administrative policy, from delivering to the Substitute Option Holder
     and/or the Substitute Share Owner, as appropriate, the Substitute Option
     Repurchase Price and the Substitute Share Repurchase Price, respectively,
     in full (and the Substitute Option Issuer shall use its reasonable best
     efforts to receive all required regulatory and legal approvals as promptly
     as practicable in order to accomplish such repurchase), the Substitute
     Option Holder and/or Substitute Share Owner may revoke its notice of
     repurchase of the Substitute Option or the Substitute Shares either in
     whole or to the extent of prohibition, whereupon, in the latter case, the
     Substitute Option Issuer shall promptly (i) deliver to the Substitute
     Option Holder or Substitute Share Owner, as appropriate, that portion of
     the Substitute Option Repurchase Price or the Substitute Share Repurchase
     Price that the Substitute Option Issuer is not prohibited from delivering;
     and (ii) deliver, as appropriate, either (A) to the Substitute Option
     Holder, a new Substitute Option evidencing the right of the Substitute
     Option Holder to purchase that number of shares of the Substitute Common
     Stock obtained by multiplying the number of shares of the Substitute Common
     Stock for which the surrendered Substitute Option was exercisable at the
     time of delivery of the notice of repurchase by a fraction, the numerator
     of which is the Substitute Option Repurchase Price less the portion thereof
     theretofore delivered to the Substitute Option Holder and the denominator
     of which is the Substitute Option Repurchase Price, and/or (B) to the
     Substitute Share Owner, a certificate for the Substitute Option Shares it
     is then so prohibited from repurchasing. If an Exercise Termination Event
     shall have occurred prior to the date of the notice by the Substitute
     Option Issuer described in the first sentence of this subsection (c), or
     shall be scheduled to occur at any time before the expiration of a period
     ending on the thirtieth day after such date, the Substitute Option Holder
     shall nevertheless have the right to exercise the Substitute Option until
     the expiration of such 30-day period.

          10.  Extension of Periods Under Certain Circumstances.  The periods
     for exercise of certain rights under Sections 2, 6, 7, 9 and 14 shall be
     extended: (i) to the extent necessary to obtain all regulatory approvals
     for the exercise of such rights (for so long as the Holder, Owner,
     Substitute

                                       B-9
<PAGE>   170

     Option Holder or Substitute Share Owner, as the case may be, is using
     commercially reasonable efforts to obtain such regulatory approvals), and
     for the expiration of all statutory waiting periods; (ii) to the extent
     necessary to avoid liability under Section 16(b) of the 1934 Act by reason
     of such exercise; and (iii) when there exists an injunction, order or
     judgment that prohibits or delays exercise of such right.

          11.  Representations and Warranties.  (a) Issuer hereby represents and
     warrants to Grantee as follows:

             (i) Issuer has the requisite 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 Issuer Board prior to the date hereof 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.

             (ii) Issuer has taken all necessary corporate action to authorize
        and reserve and to 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 Common Stock equal to the maximum number of
        shares of Common Stock at any time and from time to time issuable
        hereunder, and all such shares, upon issuance pursuant thereto, will be
        duly authorized, validly issued, fully paid, nonassessable, and will be
        delivered free and clear of all claims, liens, encumbrance and security
        interests and not subject to any preemptive rights.

          (b) Grantee hereby represents and warrants to Issuer as follows:
     Grantee has the requisite corporate power and authority to execute and
     deliver this Agreement and to perform its obligations hereunder. The
     execution and delivery of this Agreement by the Grantee and the performance
     of its obligations hereunder by the Grantee have been duly and validly
     authorized by the Board of Directors of Grantee and no other corporate
     proceedings on the part of the Grantee are necessary to authorize this
     Agreement or for Grantee to perform its obligations hereunder. This
     Agreement has been duly and validly executed and delivered by Grantee.

          (c) This Option is not being, and any Option Shares or other
     securities acquired by Grantee upon exercise of the Option will not be,
     acquired with a view to the public distribution thereof and will not be
     transferred or otherwise disposed or except in a transaction registered or
     exempt from registration under the 1933 Act.

          12.  Assignment.  Neither of the parties hereto may assign any of its
     rights or obligations under this Agreement or the Option created hereunder
     to any other person, without the express written consent of the other
     party, except that in the event an Initial Triggering Event shall have
     occurred prior to an Exercise Termination Event, Grantee, subject to the
     express provisions hereof, may assign in whole or in part its rights and
     obligations hereunder; provided, however, that until the date fifteen (15)
     days following the date on which the Federal Reserve Board or the OTS, as
     the case may be, has approved an application by Grantee to acquire the
     shares of Common Stock subject to the Option, Grantee may not assign its
     rights under the Option except in (i) a widely dispersed public
     distribution, (ii) a private placement in which no one party acquires the
     right to purchase in excess of 2% of the voting shares of Issuer, (iii) an
     assignment to a single party (e.g., a broker or investment banker) for the
     purpose of conducting a widely dispersed public distribution on Grantee's
     behalf or (iv) any other manner approved by the Federal Reserve Board or
     the OTS, as the case may be.

          13.  Filings, Etc.  Each of Grantee and Issuer will use its reasonable
     best efforts to make all filings with, and to obtain consents of, all third
     parties and governmental authorities necessary to the consummation of the
     transactions contemplated by this Agreement, including, without limitation,
     applying to the Federal Reserve Board under the BHCA for approval to
     acquire the shares issuable

                                      B-10
<PAGE>   171

     hereunder, but Grantee shall not be obligated to apply to state banking
     authorities for approval to acquire the shares of Common Stock issuable
     hereunder until such time, if ever, as it deems appropriate to do so.

          14.  Surrender of Option.  (a) Grantee may, at any time following a
     Repurchase Event and prior to the occurrence of an Exercise Termination
     Event (or such later period as provided in Section 10), relinquish the
     Option (together with any Option Shares issued to and then owned by
     Grantee) to Issuer in exchange for a cash fee equal to the Surrender Price.
     The "Surrender Price" shall be equal to $50 million (i) plus, if
     applicable, Grantee's purchase price with respect to any Option Shares and
     (ii) minus, if applicable, the excess of (A) the net price, if any,
     received by Grantee or a Grantee Subsidiary pursuant to the sale of Option
     Shares (or any other securities into which such Option Shares were
     converted or exchanged) to any unaffiliated party, over (B) Grantee's
     purchase price of such Option Shares.

          (b) Grantee may exercise its right to relinquish the Option and any
     Option Shares pursuant to this Section 14 by surrendering to Issuer, at its
     principal office, a copy of this Agreement together with certificates for
     Option Shares, if any, accompanied by a written notice stating (i) that
     Grantee elects to relinquish the Option and Option Shares, if any, in
     accordance with the provisions of this Section 14 and (ii) the Surrender
     Price. The Surrender Price shall be payable in immediately available funds
     on or before the second business day following receipt of such notice by
     Issuer.

          (c) To the extent that Issuer is prohibited under applicable law or
     regulation, or as a consequence of administrative policy, from paying the
     Surrender Price to Grantee in full, Issuer shall immediately so notify
     Grantee and thereafter deliver or cause to be delivered, from time to time,
     to Grantee, the portion of the Surrender Price that it is no longer
     prohibited from paying, within five (5) business days after the date on
     which Issuer is no longer so prohibited; provided, however, that if Issuer
     at any time after delivery of a notice of surrender pursuant to paragraph
     (b) of this Section 14 is prohibited under applicable law or regulation, or
     as a consequence of administrative policy, from paying to Grantee the
     Surrender Price in full, (i) Issuer shall (A) use its reasonable best
     efforts to obtain all required regulatory and legal approvals and to file
     any required notices as promptly as practicable in order to make such
     payments, (B) within five (5) days of the submission or receipt of any
     documents relating to any such regulatory and legal approvals, provide
     Grantee with copies of the same and (c) keep Grantee advised of both the
     status of any such request for regulatory and legal approvals, as well as
     any discussions with any relevant regulatory or other third party
     reasonably related to the same and (ii) Grantee may revoke such notice of
     surrender by delivery of a notice of revocation to Issuer and, upon
     delivery of such notice of revocation, the Exercise Termination Date shall
     be extended to a date six (6) months from the date on which the Exercise
     Termination Date would have occurred if not for the provisions of this
     Section 14(c) (during which period Grantee may exercise any of its rights
     hereunder, including any and all rights pursuant to this Section 14).

          15.  Specific Performance.  The parties hereto acknowledge that
     damages would be an inadequate remedy for a breach of this Agreement by
     either party hereto and that the obligations of the parties hereto shall be
     enforceable by either party hereto through injunctive or other equitable
     relief. In connection therewith, both parties waive the posting of any bond
     or similar requirement.

          16.  Severability.  If any term, provision, covenant or restriction
     contained in this Agreement is held by a court or a federal or state
     regulatory agency of competent jurisdiction to be invalid, void or
     unenforceable, the remainder of the terms, provisions and covenants and
     restrictions contained in 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 agency determines that the Holder is
     not permitted to acquire, or Issuer is not permitted to repurchase pursuant
     to Section 7, the full number of shares of Common Stock provided in Section
     l(a) hereof (as adjusted pursuant to Section l(b) or Section 5 hereof), it
     is the express intention of Issuer to allow the Holder to acquire or to
     require Issuer to repurchase such lesser number of shares as may be
     permissible, without any amendment or modification hereof.

                                      B-11

          17.  Notices.  All notices, requests, claims, demands and other
     communications hereunder shall be deemed to have been duly given when
     delivered in person, by fax, telecopy, or by registered or certified mail
     (postage prepaid, return receipt requested) at the respective addresses of
     the parties set forth in the Merger Agreement.

          18.  Governing Law.  This Agreement shall be governed by and construed
     in accordance with the laws of the State of New York.

          19.  Counterparts.  This Agreement may be executed in two or more
     counterparts, each of which shall be deemed to be an original, but all of
     which shall constitute one and the same agreement.

          20.  Expenses.  Except as otherwise expressly provided herein, 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,

     STOCK OPTION AGREEMENT, dated as of September 16, 1999 (this "Agreement"),
between Dime Bancorp, Inc., a Delaware corporation ("Grantee"), and Hudson
United Bancorp, a New Jersey corporation ("Issuer").

                                    RECITALS

     A.  Merger Agreement.  Grantee and Issuer have entered into an Agreement
and Plan of Merger, dated as of September 15, 1999 (the "Merger Agreement"),
which agreement was executed and delivered on the day preceding the date of this
Stock Option Agreement, pursuant to which Issuer is to merge with and into
Grantee (the "Merger"); and

     B.  Option.  As a condition to Grantee's entering into the Merger Agreement
and in consideration therefor, Issuer has agreed to grant Grantee the Option (as
hereinafter defined).

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein and in the Merger Agreement, the parties hereto
agree as follows:

          1.  Grant of Option.  (a) Issuer hereby grants to Grantee an
     unconditional, irrevocable option (the "Option") to purchase, subject to
     the terms hereof, up to an aggregate of 8,139,081 fully paid and
     nonassessable shares of the common stock, no par value per share, of Issuer
     ("Common Stock") at a price per share equal to $30 1/8; provided, however,
     that in no event shall the number of shares for which this Option is
     exercisable exceed 19.9% of the issued and outstanding shares of Common
     Stock. The number of shares of Common Stock that may be received upon the
     exercise of the Option and the Option Price are subject to adjustment as
     herein set forth.

          (b) In the event that any additional shares of Common Stock are issued
     or otherwise become outstanding after the date of this Agreement (other
     than pursuant to this Agreement and other than pursuant to an event
     described in Section 5(a) hereof), the number of shares of Common Stock
     subject to the Option shall be increased so that, after such issuance, such
     number together with any shares of Common Stock previously issued pursuant
     hereto, equals 19.9% of the number of shares of Common Stock then issued
     and outstanding without giving effect to any shares subject or issued
     pursuant to the Option. Nothing contained in this Section 1(b) or elsewhere
     in this Agreement shall be deemed to authorize Issuer to issue shares in
     breach of any provision of the Merger Agreement.

          2.  Exercise.  (a) The Holder (as hereinafter defined) may exercise
     the Option, in whole or part, if, but only if, both an Initial Triggering
     Event (as hereinafter defined) and a Subsequent Triggering Event (as
     hereinafter defined) shall have occurred prior to the occurrence of an
     Exercise Termination Event (as hereinafter defined), provided that the
     Holder shall have sent the written notice of such exercise (as provided in
     subsection (e) of this Section 2) within six (6) months following such
     Subsequent Triggering Event (or such later period as provided in Section
     10). Each of the following shall be an Exercise Termination Event: (i) the
     Effective Time (as defined in the Merger Agreement) of the Merger; (ii)
     termination of the Merger Agreement in accordance with the provisions
     thereof if such termination occurs prior to the occurrence of an Initial
     Triggering Event except a termination by Grantee pursuant to Section 8.4(a)
     of the Merger Agreement (unless the breach by Issuer giving rise to such
     right of termination is non-volitional) (a "Listed Termination"); or (iii)
     the passage of eighteen (18) months (or such longer period as provided in
     Section 10) after termination of the Merger Agreement if such termination
     follows the occurrence of an Initial Triggering Event or is a Listed
     Termination. The term "Holder" shall mean the holder or holders of the
     Option. Notwithstanding anything to the contrary contained herein, the
     Option may not be exercised at any time when Grantee shall be in material
     breach of any of its covenants or agreements contained in the Merger
     Agreement such that Issuer shall be entitled to terminate the Merger
     Agreement pursuant to Section 8.3(a) thereof.
<PAGE>   174

          (b) The term "Initial Triggering Event" shall mean any of the
     following events or transactions occurring on or after the date hereof:

             (i) Issuer or any of its Significant Subsidiaries (as defined in
        Rule 1-02 of Regulation S-X promulgated by the Securities and Exchange
        Commission (the "SEC")) (the "Issuer Subsidiaries"), without having
        received Grantee's prior written consent, shall have entered into an
        agreement to engage in an Acquisition Transaction (as hereinafter
        defined) 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 Securities Exchange Act of 1934, as amended (the "1934
        Act"), and the rules and regulations thereunder) other than Grantee or
        any of its Subsidiaries (each a "Grantee Subsidiary") or the Board of
        Directors of Issuer (the "Issuer Board") shall have recommended that the
        stockholders of Issuer approve or accept any Acquisition Transaction
        other than as contemplated by the Merger Agreement. For purposes of this
        Agreement, (a) "Acquisition Transaction" shall mean (x) a merger or
        consolidation, or any similar transaction, involving Issuer or any
        Issuer Subsidiary (other than mergers, consolidations or similar
        transactions involving solely Issuer and/or one or more wholly-owned
        Subsidiaries of the Issuer, provided, any such transaction is not
        entered into in violation of the terms of the Merger Agreement), (y) a
        purchase, lease or other acquisition of all or any substantial part of
        the assets or deposits of Issuer or any Issuer Subsidiary, or (z) a
        purchase or other acquisition (including by way of merger,
        consolidation, share exchange or otherwise) of securities representing
        10% or more of the voting power of Issuer or any Issuer Subsidiary and
        (b) "Subsidiary" shall have the meaning set forth in Rule 12b-2 under
        the 1934 Act;

             (ii) Any person other than the Grantee or any Grantee Subsidiary
        shall have acquired beneficial ownership or the right to acquire
        beneficial ownership of 10% or more of the outstanding shares of Common
        Stock (the term "beneficial ownership" for purposes of this Agreement
        having the meaning assigned thereto in Section 13(d) of the 1934 Act,
        and the rules and regulations thereunder);

             (iii) The stockholders of Issuer shall have voted and failed to
        approve the Merger Agreement and the Merger at a meeting which has been
        held for that purpose or any adjournment or postponement thereof, or
        such meeting shall not have been held in violation of the Merger
        Agreement or shall have been canceled prior to termination of the Merger
        Agreement if, prior to such meeting (or if such meeting shall not have
        been held or shall have been canceled, prior to such termination), it
        shall have been publicly announced that any person (other than Grantee
        or any of its Subsidiaries) shall have made, or disclosed an intention
        to make, a proposal to engage in an Acquisition Transaction;

             (iv) The Issuer Board shall have withdrawn, modified or qualified
        (or publicly announced its intention to withdraw, modify or qualify) in
        any manner adverse in any respect to Grantee its recommendation that the
        stockholders of Issuer approve the transactions contemplated by the
        Merger Agreement in anticipation of engaging in an Acquisition
        Transaction, or Issuer or any Issuer Subsidiary shall have authorized,
        recommended, proposed (or publicly announced its intention to authorize,
        recommend or propose) an agreement to engage in an Acquisition
        Transaction with any person other than Grantee or a Grantee Subsidiary;

             (v) Any person other than Grantee or any Grantee Subsidiary shall
        have filed with the SEC a registration statement or tender offer
        materials with respect to a potential exchange or tender offer that
        would constitute an Acquisition Transaction (or filed a preliminary
        proxy statement with the SEC with respect to a potential vote by its
        stockholders to approve the issuance of shares to be offered in such an
        exchange offer);

             (vi) Issuer shall have willfully breached any covenant or
        obligation contained in the Merger Agreement after an overture is made
        by a third party to Issuer or its stockholders to engage in an
        Acquisition Transaction, and (a) following such breach Grantee would be
        entitled to terminate the Merger Agreement (whether immediately or after
        the giving of notice or passage of time or
                                       C-2
<PAGE>   175

        both) and (b) such breach shall not have been cured prior to the Notice
        Date (as defined in Section 2(e)); or

             (vii) Any person other than Grantee or any Grantee Subsidiary,
        without Grantee's prior written consent, shall have filed an application
        or notice with the Board of Governors of the Federal Reserve System (the
        "Federal Reserve Board"), the Office of Thrift Supervision (the "OTS")
        or other federal or state bank regulatory or antitrust authority, which
        application or notice has been accepted for processing, for approval to
        engage in an Acquisition Transaction.

          (c) The term "Subsequent Triggering Event" shall mean any of the
     following events or transactions occurring after the date hereof:

             (i) The acquisition by any person (other than Grantee or any
        Grantee Subsidiary) of beneficial ownership of 25% or more of the then
        outstanding Common Stock; or

             (ii) The occurrence of the Initial Triggering Event described in
        clause (i) of subsection (b) of this Section 2, except that the
        percentage referred to in clause (z) of the second sentence thereof
        shall be 25%.

          (d) Issuer shall notify Grantee promptly in writing of the occurrence
     of any Initial Triggering Event or Subsequent Triggering Event (together, a
     "Triggering Event"), it being understood that the giving of such notice by
     Issuer shall not be a condition to the right of the Holder to exercise the
     Option.

          (e) In the event the Holder is entitled to and wishes to exercise the
     Option (or any portion thereof), it shall send to Issuer a written notice
     (the date of which being herein referred to as the "Notice Date")
     specifying (i) the total number of shares it will purchase pursuant to such
     exercise and (ii) a place and date not earlier than three business days nor
     later than 60 business days from the Notice Date for the closing of such
     purchase (the "Closing Date"); provided, that if prior notification to or
     approval of the Federal Reserve Board or any other regulatory or antitrust
     agency is required in connection with such purchase, the Holder shall
     promptly file the required notice or application for approval, shall
     promptly notify Issuer of such filing and shall expeditiously process the
     same and the period of time that otherwise would run pursuant to this
     sentence shall run instead from the date on which any required notification
     periods have expired or been terminated or such approvals have been
     obtained and any requisite waiting period or periods shall have passed. Any
     exercise of the Option shall be deemed to occur on the Notice Date relating
     thereto.

          (f) At the closing referred to in subsection (e) of this Section 2,
     the Holder shall (i) pay to Issuer the aggregate purchase price for the
     shares of Common Stock purchased pursuant to the exercise of the Option in
     immediately available funds by wire transfer to a bank account designated
     by Issuer and (ii) present and surrender this Agreement to Issuer at its
     principal executive offices, provided that the failure or refusal of the
     Issuer to designate such a bank account or accept surrender of this
     Agreement shall not preclude the Holder from exercising the Option.

          (g) At such closing, simultaneously with the delivery of immediately
     available funds as provided in subsection (f) of this Section 2, Issuer
     shall deliver to the Holder a certificate or certificates representing the
     number of shares of Common Stock purchased by the Holder and, if the Option
     should be exercised in part only, a new Option evidencing the rights of the
     Holder thereof to purchase the balance of the shares purchasable hereunder.

          (h) Certificates for Common Stock delivered at a closing hereunder may
     be endorsed with a restrictive legend that shall read substantially as
     follows:

             "The transfer of the shares represented by this certificate is
        subject to certain provisions of an agreement between the registered
        holder hereof and Issuer and to resale restrictions arising under the
        Securities Act of 1933, as amended. A copy of such agreement is on file
        at the principal office of Issuer and will be provided to the holder
        hereof without charge upon receipt by Issuer of a written request
        therefor."
                                       C-3
<PAGE>   176

     It is understood and agreed that: (i) the reference to the resale
     restrictions of the Securities Act of 1933, as amended (the "1933 Act") in
     the above legend shall be removed by delivery of substitute certificate(s)
     without such reference if the Holder shall have delivered to Issuer a copy
     of a letter from the staff of the SEC, or an opinion of counsel, in form
     and substance reasonably satisfactory to Issuer, to the effect that such
     legend is not required for purposes of the 1933 Act; (ii) the reference to
     the provisions of this Agreement in the above legend shall be removed by
     delivery of substitute certificate(s) without such reference if the shares
     have been sold or transferred in compliance with the provisions of this
     Agreement and under circumstances that do not require the retention of such
     reference in the opinion of counsel to the Holder, in form and substance
     reasonably satisfactory to the Issuer; and (iii) the legend shall be
     removed in its entirety if the conditions in the preceding clauses (i) and
     (ii) are both satisfied. In addition, such certificates shall bear any
     other legend as may be required by law.

          (i) Upon the giving by the Holder to Issuer of the written notice of
     exercise of the Option provided for under subsection (e) of this Section 2
     and the tender of the applicable purchase price in immediately available
     funds, the Holder shall be deemed to be the holder of record of the shares
     of 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 Common Stock shall not then be actually
     delivered to the 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, issue and delivery of stock
     certificates under this Section 2 in the name of the Holder or its
     assignee, transferee or designee.

          3.  Covenants of Issuer.  Issuer agrees: (i) that it shall at all
     times maintain, free from preemptive rights, sufficient authorized but
     unissued or treasury shares of Common Stock so that the Option may be
     exercised without additional authorization of Common Stock after giving
     effect to all other options, warrants, convertible securities and other
     rights to purchase 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 (x)
     complying with all applicable premerger notification, reporting and waiting
     period requirements specified in 15 U.S.C. Section 18a and regulations
     promulgated thereunder and (y) in the event, under the Bank Holding Company
     Act of 1956, as amended (the "BHCA"), the Home Owners' Loan Act, as amended
     (the "HOLA") or the Change in Bank Control Act of 1978, as amended, or any
     state or other federal banking law, prior approval of or notice to the
     Federal Reserve Board, the OTS or to any state or other federal regulatory
     authority is necessary before the Option may be exercised, cooperating
     fully with the Holder in preparing such applications or notices and
     providing such information to the Federal Reserve Board, the OTS or such
     state or other federal regulatory authority as they may require) in order
     to permit the Holder to exercise the Option and Issuer duly and effectively
     to issue shares of Common Stock pursuant hereto; and (iv) promptly to take
     all action provided herein to protect the rights of the Holder against
     dilution.

          4.  Exchange.  This Agreement (and the Option granted hereby) are
     exchangeable, without expense, at the option of the 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, on the same terms
     and subject to the same conditions as are set forth herein, in the
     aggregate the same number of shares of Common Stock purchasable hereunder.
     The terms "Agreement" and "Option" as used herein include any 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

                                       C-4
<PAGE>   177

     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.

          5.  Certain Adjustments.  In addition to the adjustment in the number
     of shares of Common Stock that are purchasable upon exercise of the Option
     pursuant to Section 1 of this Agreement, the number of shares of Common
     Stock purchasable upon the exercise of the Option and the Option Price
     shall be subject to adjustment from time to time as provided in this
     Section 5. In the event of any change in Common Stock by reason of a stock
     dividend, stock split, split-up, recapitalization, stock combination,
     exchange of shares or similar transaction, the type and number of shares or
     securities subject to the Option, and the Option Price therefor, shall be
     adjusted appropriately, and proper provision shall be made in the
     agreements governing such transaction so that Grantee shall receive, upon
     exercise of the Option, the number and class of shares or other securities
     or property that Grantee would have received in respect of 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 Common
     Stock are issued after the date of this Agreement (other than pursuant to
     an event described in the first sentence of this Section 5), the number of
     shares of Common Stock subject to the Option shall be adjusted so that,
     after such issuance, it, together with any shares of Common Stock
     previously issued pursuant hereto, equals 19.9% of the number of shares of
     Common Stock then issued and outstanding, without giving effect to any
     shares subject to or issued pursuant to the Option.

          6.  Registration Rights.  Upon the occurrence of a Subsequent
     Triggering Event that occurs prior to an Exercise Termination Event, Issuer
     shall, at the request of Grantee delivered within twelve (12) months (or
     such later period as provided in Section 10) of such Subsequent Triggering
     Event (whether on its own behalf or on behalf of any subsequent holder of
     this Option (or part thereof) or any of the shares of Common Stock issued
     pursuant hereto), promptly prepare, file and keep current a registration
     statement under the 1933 Act covering any shares issued and issuable
     pursuant to this Option and shall use its reasonable best efforts to cause
     such registration statement to become effective and remain current in order
     to permit the sale or other disposition of any shares of Common Stock
     issued upon total or partial exercise of this Option ("Option Shares") in
     accordance with any plan of disposition requested by Grantee. Issuer will
     use its reasonable best efforts to cause such registration statement
     promptly to become effective and then to remain effective for such period
     not in excess of 180 days from the day such registration statement first
     becomes effective or such shorter time as may be reasonably necessary to
     effect such sales or other dispositions. Grantee shall have the right to
     demand two such registrations. The Issuer shall bear the costs of such
     registrations (including, but not limited to, Issuer's attorneys' fees,
     printing costs and filing fees, except for underwriting discounts or
     commissions, brokers' fees and the fees and disbursements of Grantee's
     counsel related thereto). The foregoing notwithstanding, if, at the time of
     any request by Grantee for registration of Option Shares as provided above,
     Issuer is in registration with respect to an underwritten public offering
     by Issuer of shares of Common Stock, and if in the good faith judgment of
     the managing underwriter or managing underwriters, or, if none, the sole
     underwriter or underwriters, of such offering the offer and sale of the
     Option Shares would interfere with the successful marketing of the shares
     of Common Stock offered by Issuer, the number of Option Shares otherwise to
     be covered in the registration statement contemplated hereby may be
     reduced; provided, however, that after any such required reduction the
     number of Option Shares to be included in such offering for the account of
     the Holder shall constitute at least 33 1/3% of the total number of shares
     to be sold by the Holder and Issuer in the aggregate; and provided further,
     however, that if such reduction occurs, then Issuer shall file a
     registration statement for the balance as promptly as practicable
     thereafter as to which no reduction pursuant to this Section 6 shall be
     permitted or occur and the Holder shall thereafter be entitled to one
     additional registration and the twelve (12) month period referred to in the
     first sentence of this section shall be increased to twenty-four (24)
     months. Each such Holder shall provide all information reasonably requested
     by Issuer for inclusion in any registration statement to be filed
     hereunder. If requested by any such Holder in connection with such
     registration, Issuer shall become a party to any underwriting agreement
     relating to the sale of such
                                       C-5

     shares, but only to the extent of obligating itself in respect of
     representations, warranties, indemnities and other agreements customarily
     included in such underwriting agreements for Issuer. Upon receiving any
     request under this Section 6 from any Holder, Issuer agrees to send a copy
     thereof to any other person known to Issuer to be entitled to registration
     rights under this Section 6, in each case by promptly mailing the same,
     postage prepaid, to the address of record of the persons entitled to
     receive such copies. Notwithstanding anything to the contrary contained
     herein, in no event shall the number of registrations that Issuer is
     obligated to effect be increased by reason of the fact that there shall be
     more than one Holder as a result of any assignment or division of this
     Agreement.

          7.  Repurchase.  (a) At any time after the occurrence of a Repurchase
     Event (as defined below) (i) at the request of the Holder, delivered prior
     to an Exercise Termination Event (or such later period as provided in
     Section 10), Issuer (or any successor thereto) shall repurchase the Option
     from the Holder at a price (the "Option Repurchase Price") equal to the
     amount by which (A) the market/offer price (as defined below) exceeds (B)
     the Option Price, multiplied by the number of shares for which this Option
     may then be exercised and (ii) at the request of the owner of Option Shares
     from time to time (the "Owner"), delivered prior to an Exercise Termination
     Event (or such later period as provided in Section 10), Issuer (or any
     successor thereto) shall repurchase such number of the Option Shares from
     the Owner as the Owner shall designate at a price (the "Option Share
     Repurchase Price") equal to the market/offer price multiplied by the number
     of Option Shares so designated. The term "market/offer price" shall mean
     the highest of (i) the price per share of Common Stock at which a tender or
     exchange offer therefor has been made, (ii) the price per share of Common
     Stock to be paid by any third party pursuant to an agreement with Issuer,
     (iii) the highest closing price for shares of Common Stock within the
     six-month period immediately preceding the date the Holder gives notice of
     the required repurchase of this Option or the Owner gives notice of the
     required repurchase of Option Shares, as the case may be, or (iv) in the
     event of a sale of all or any substantial part of Issuer's assets or
     deposits, the sum of the net price paid in such sale for such assets or
     deposits and the current market value of the remaining net assets of Issuer
     as determined by a nationally recognized investment banking firm selected
     by the Holder or the Owner, as the case may be, and reasonably acceptable
     to Issuer, divided by the number of shares of Common Stock of Issuer
     outstanding at the time of such sale. In determining the market/offer
     price, the value of consideration other than cash shall be determined by a
     nationally recognized investment banking firm selected by the Holder or
     Owner, as the case may be, and reasonably acceptable to Issuer.

          (b) The Holder and the Owner, as the case may be, may exercise its
     right to require Issuer to repurchase the Option and any Option Shares
     pursuant to this Section 7 by surrendering for such purpose to Issuer, at
     its principal office, a copy of this Agreement or certificates for Option
     Shares, as applicable, accompanied by a written notice or notices stating
     that the Holder or the Owner, as the case may be, elects to require Issuer
     to repurchase this Option and/or the Option Shares in accordance with the
     provisions of this Section 7. The Holder shall also represent and warrant
     that it has sole record and beneficial ownership of such Option Shares and
     that such Option Shares are then free and clear of all liens. As promptly
     as practicable, and in any event within five (5) business days after the
     surrender of the Option and/or certificates representing Option Shares and
     the receipt of such notice or notices relating thereto, Issuer shall
     deliver or cause to be delivered to the Holder the Option Repurchase Price
     and/or to the Owner the Option Share Repurchase Price therefor or the
     portion thereof that Issuer is not then prohibited under applicable law and
     regulation from so delivering.

          (c) To the extent that Issuer is prohibited under applicable law or
     regulation, or as a consequence of administrative policy, from repurchasing
     the Option and/or the Option Shares in full, Issuer shall immediately so
     notify the Holder and/or the Owner and thereafter deliver or cause to be
     delivered, from time to time, to the Holder and/or the Owner, as
     appropriate, the portion of the Option Repurchase Price and the Option
     Share Repurchase Price, respectively, that it is no longer prohibited from
     delivering, within five (5) business days after the date on which Issuer is
     no longer so prohibited; provided, however, that if Issuer at any time
     after delivery of a notice of repurchase

                                       C-6
<PAGE>   179

     pursuant to paragraph (b) of this Section 7 is prohibited under applicable
     law or regulation, or as a consequence of administrative policy, from
     delivering to the Holder and/or the Owner, as appropriate, the Option
     Repurchase Price and the Option Share Repurchase Price, respectively, in
     full (and Issuer hereby undertakes to use its reasonable best efforts to
     obtain all required regulatory and legal approvals and to file any required
     notices as promptly as practicable in order to accomplish such repurchase),
     the Holder or Owner may revoke its notice of repurchase of the Option
     and/or the Option Shares whether in whole or to the extent of the
     prohibition, whereupon, in the latter case, Issuer shall promptly (i)
     deliver to the Holder and/or the Owner, as appropriate, that portion of the
     Option Repurchase Price and/or the Option Share Repurchase Price that
     Issuer is not prohibited from delivering; and (ii) deliver, as appropriate,
     either (A) to the Holder, a new Agreement evidencing the right of the
     Holder to purchase that number of shares of Common Stock obtained by
     multiplying the number of shares of Common Stock for which the surrendered
     Agreement was exercisable at the time of delivery of the notice of
     repurchase by a fraction, the numerator of which is the Option Repurchase
     Price less the portion thereof theretofore delivered to the Holder and the
     denominator of which is the Option Repurchase Price, and/or (B) to the
     Owner, a certificate for the Option Shares it is then so prohibited from
     repurchasing. If an Exercise Termination Event shall have occurred prior to
     the date of the notice by Issuer described in the first sentence of this
     subsection (c), or shall be scheduled to occur at any time before the
     expiration of a period ending on the thirtieth day after such date, the
     Holder shall nonetheless have the right to exercise the Option until the
     expiration of such 30 day period.

          (d) For purposes of this Section 7, a "Repurchase Event" shall be
     deemed to have occurred upon the occurrence of any of the following events
     or transactions after the date hereof:

             (i) the acquisition by any person (other than Grantee or any
        Grantee Subsidiary) of beneficial ownership of 50% or more of the then
        outstanding Common Stock; or

             (ii) the consummation of any Acquisition Transaction described in
        Section 2(b)(i) hereof, except that the percentage referred to in clause
        (z) shall be 25%.

          8.  Substitute Option.  (a) In the event that prior to an Exercise
     Termination Event, Issuer shall enter into an agreement (i) to consolidate
     with or merge into any person, other than Grantee or a Grantee Subsidiary,
     or engage in a plan of exchange with any person, other than Grantee or a
     Grantee Subsidiary and Issuer shall not be the continuing or surviving
     corporation of such consolidation or merger or the acquirer in such plan of
     exchange, (ii) to permit any person, other than Grantee or a Grantee
     Subsidiary, to merge into Issuer or be acquired by Issuer in a plan of
     exchange and Issuer shall be the continuing or surviving or acquiring
     corporation, but, in connection with such merger or plan of exchange, the
     then outstanding shares of Common Stock shall be changed into or exchanged
     for stock or other securities of any other person or cash or any other
     property or the then outstanding shares of Common Stock shall after such
     merger or plan of exchange represent less than 50% of the outstanding
     shares and share equivalents of the merged or acquiring company, or (iii)
     to sell or otherwise transfer all or a substantial part of its or any
     Issuer Subsidiary's assets or deposits to any person, other than Grantee or
     a Grantee Subsidiary, then, and in each such case, the agreement governing
     such transaction shall make proper provision 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 the Holder, of either (x) the
     Acquiring Corporation (as hereinafter defined) or (y) any person that
     controls the Acquiring Corporation.

          (b) The following terms have the meanings indicated:

             (i) "Acquiring Corporation" shall mean (i) the continuing or
        surviving person of a consolidation or merger with Issuer (if other than
        Issuer), (ii) the acquiring person in a plan of exchange in which Issuer
        is acquired, (iii) the Issuer in a merger or plan of exchange in which
        Issuer is the continuing or surviving or acquiring person and (iv) the
        transferee of all or a substantial part of Issuer's assets or deposits
        (or the assets or deposits of any Issuer Subsidiary).
                                       C-7
<PAGE>   180

             (ii) "Substitute Common Stock" shall mean the common stock issued
        by the issuer of the Substitute Option upon exercise of the Substitute
        Option.

             (iii) "Assigned Value" shall mean the market/offer price, as
        defined in Section 7.

             (iv) "Average Price" shall mean the average closing price of a
        share of the Substitute Common Stock for one (1) 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 the
        person merging into Issuer or by any company which controls or is
        controlled by such person, as the Holder may elect.

          (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 the Holder. The issuer of the
     Substitute Option shall also enter into an agreement with the then Holder
     or Holders of the Substitute Option in substantially the same form as this
     Agreement (after giving effect for such purpose to the provisions of
     Section 9), which agreement shall be applicable to the Substitute Option.

          (d) The Substitute Option shall be exercisable for such number of
     shares of Substitute Common Stock as is equal to the Assigned Value
     multiplied by the number of shares of Common Stock for which the Option was
     exercisable immediately prior to the event described in the first sentence
     of Section 8(a), divided by the Average Price. The exercise price of the
     Substitute Option per share of Substitute Common Stock shall then be equal
     to the Option Price multiplied by a fraction, the numerator of which shall
     be the number of shares of Common Stock for which the Option was
     exercisable immediately prior to the event described in the first sentence
     of Section 8(a) and the denominator of which shall be the number of shares
     of Substitute Common Stock for which the Substitute Option is exercisable.

          (e) In no event, pursuant to any of the foregoing paragraphs, shall
     the Substitute Option be exercisable for more than 19.9% 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 shares of Substitute Common Stock outstanding prior
     to exercise but for this clause (e), the issuer of the Substitute Option
     (the "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 this clause (e) over (ii) the value of the
     Substitute Option after giving effect to the limitation in this clause (e).
     This difference in value shall be determined by a nationally recognized
     investment banking firm selected by the Holder.

          (f) Issuer shall not enter into any transaction described in
     subsection (a) of this Section 8 unless the Acquiring Corporation and any
     person that controls the Acquiring Corporation assume in writing all the
     obligations of Issuer hereunder.

          9.  Repurchase of Substitute Option.  (a) At the request of the holder
     of the Substitute Option (the "Substitute Option Holder"), the Substitute
     Option Issuer shall repurchase the Substitute Option from the Substitute
     Option Holder at a price (the "Substitute Option Repurchase Price") equal
     to the amount by which (i) the Highest Closing Price (as hereinafter
     defined) exceeds (ii) the exercise price of the Substitute Option,
     multiplied by the number of shares of Substitute Common Stock for which the
     Substitute Option may then be exercised, and at the request of the owner
     (the "Substitute Share Owner") of shares of Substitute Common Stock (the
     "Substitute Shares"), the Substitute Option Issuer shall repurchase the
     Substitute Shares at a price (the "Substitute Share Repurchase Price")
     equal to the Highest Closing Price multiplied by the number of Substitute
     Shares so designated. The term "Highest Closing Price" shall mean the
     highest closing price for shares of Substitute Common Stock within the
     six-month period immediately preceding the date the Substitute

                                       C-8
<PAGE>   181

     Option Holder gives notice of the required repurchase of the Substitute
     Option or the Substitute Share Owner gives notice of the required
     repurchase of the Substitute Shares, as applicable.

          (b) The Substitute Option Holder and the Substitute Share Owner, as
     the case may be, may exercise its respective rights to require the
     Substitute Option Issuer to repurchase the Substitute Option and the
     Substitute Shares pursuant to this Section 9 by surrendering for such
     purpose to the Substitute Option Issuer, at its principal office, the
     agreement for such Substitute Option (or, in the absence of such an
     agreement, a copy of this Agreement) and/or certificates for Substitute
     Shares accompanied by a written notice or notices stating that the
     Substitute Option Holder or the Substitute Share Owner, as the case may be,
     elects to require the Substitute Option Issuer to repurchase the Substitute
     Option and/or the Substitute Shares in accordance with the provisions of
     this Section 9. As promptly as practicable and in any event within five (5)
     business days after the surrender of the Substitute Option and/or
     certificates representing Substitute Shares and the receipt of such notice
     or notices relating thereto, the Substitute Option Issuer shall deliver or
     cause to be delivered to the Substitute Option Holder the Substitute Option
     Repurchase Price and/or to the Substitute Share Owner the Substitute Share
     Repurchase Price therefor or the portion thereof which the Substitute
     Option Issuer is not then prohibited under applicable law and regulation
     from so delivering.

          (c) To the extent that the Substitute Option Issuer is prohibited
     under applicable law or regulation, or as a consequence of administrative
     policy, from repurchasing the Substitute Option and/or the Substitute
     Shares in part or in full, the Substitute Option Issuer shall immediately
     so notify the Substitute Option Holder and/or the Substitute Share Owner
     and thereafter deliver or cause to be delivered, from time to time, to the
     Substitute Option Holder and/or the Substitute Share Owner, as appropriate,
     the portion of the Substitute Option Repurchase Price and/or the Substitute
     Share Repurchase Price, respectively, which it is no longer prohibited from
     delivering, within five (5) business days after the date on which the
     Substitute Option Issuer is no longer so prohibited; provided, however,
     that if the Substitute Option Issuer is at any time after delivery of a
     notice of repurchase pursuant to subsection (b) of this Section 9
     prohibited under applicable law or regulation, or as a consequence of
     administrative policy, from delivering to the Substitute Option Holder
     and/or the Substitute Share Owner, as appropriate, the Substitute Option
     Repurchase Price and the Substitute Share Repurchase Price, respectively,
     in full (and the Substitute Option Issuer shall use its reasonable best
     efforts to receive all required regulatory and legal approvals as promptly
     as practicable in order to accomplish such repurchase), the Substitute
     Option Holder and/or Substitute Share Owner may revoke its notice of
     repurchase of the Substitute Option or the Substitute Shares either in
     whole or to the extent of prohibition, whereupon, in the latter case, the
     Substitute Option Issuer shall promptly (i) deliver to the Substitute
     Option Holder or Substitute Share Owner, as appropriate, that portion of
     the Substitute Option Repurchase Price or the Substitute Share Repurchase
     Price that the Substitute Option Issuer is not prohibited from delivering;
     and (ii) deliver, as appropriate, either (A) to the Substitute Option
     Holder, a new Substitute Option evidencing the right of the Substitute
     Option Holder to purchase that number of shares of the Substitute Common
     Stock obtained by multiplying the number of shares of the Substitute Common
     Stock for which the surrendered Substitute Option was exercisable at the
     time of delivery of the notice of repurchase by a fraction, the numerator
     of which is the Substitute Option Repurchase Price less the portion thereof
     theretofore delivered to the Substitute Option Holder and the denominator
     of which is the Substitute Option Repurchase Price, and/or (B) to the
     Substitute Share Owner, a certificate for the Substitute Option Shares it
     is then so prohibited from repurchasing. If an Exercise Termination Event
     shall have occurred prior to the date of the notice by the Substitute
     Option Issuer described in the first sentence of this subsection (c), or
     shall be scheduled to occur at any time before the expiration of a period
     ending on the thirtieth day after such date, the Substitute Option Holder
     shall nevertheless have the right to exercise the Substitute Option until
     the expiration of such 30-day period.

          10.  Extension of Periods Under Certain Circumstances.  The periods
     for exercise of certain rights under Sections 2, 6, 7, 9 and 14 shall be
     extended: (i) to the extent necessary to obtain all regulatory approvals
     for the exercise of such rights (for so long as the Holder, Owner,
     Substitute

                                       C-9
<PAGE>   182

     Option Holder or Substitute Share Owner, as the case may be, is using
     commercially reasonable efforts to obtain such regulatory approvals), and
     for the expiration of all statutory waiting periods; (ii) to the extent
     necessary to avoid liability under Section 16(b) of the 1934 Act by reason
     of such exercise; and (iii) when there exists an injunction, order or
     judgment that prohibits or delays exercise of such right.

          11.  Representations and Warranties.  (a) Issuer hereby represents and
     warrants to Grantee as follows:

             (i) Issuer has the requisite 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 Issuer Board prior to the date hereof 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.

             (ii) Issuer has taken all necessary corporate action to authorize
        and reserve and to 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 Common Stock equal to the maximum number of
        shares of Common Stock at any time and from time to time issuable
        hereunder, and all such shares, upon issuance pursuant thereto, will be
        duly authorized, validly issued, fully paid, nonassessable, and will be
        delivered free and clear of all claims, liens, encumbrance and security
        interests and not subject to any preemptive rights.

          (b) Grantee hereby represents and warrants to Issuer as follows:
     Grantee has the requisite corporate power and authority to execute and
     deliver this Agreement and to perform its obligations hereunder. The
     execution and delivery of this Agreement by the Grantee and the performance
     of its obligations hereunder by the Grantee have been duly and validly
     authorized by the Board of Directors of Grantee and no other corporate
     proceedings on the part of the Grantee are necessary to authorize this
     Agreement or for Grantee to perform its obligations hereunder. This
     Agreement has been duly and validly executed and delivered by Grantee.

          (c) This Option is not being, and any Option Shares or other
     securities acquired by Grantee upon exercise of the Option will not be,
     acquired with a view to the public distribution thereof and will not be
     transferred or otherwise disposed or except in a transaction registered or
     exempt from registration under the 1933 Act.

          12.  Assignment.  Neither of the parties hereto may assign any of its
     rights or obligations under this Agreement or the Option created hereunder
     to any other person, without the express written consent of the other
     party, except that in the event an Initial Triggering Event shall have
     occurred prior to an Exercise Termination Event, Grantee, subject to the
     express provisions hereof, may assign in whole or in part its rights and
     obligations hereunder; provided, however, that until the date fifteen (15)
     days following the date on which the Federal Reserve Board or the OTS, as
     the case may be, has approved an application by Grantee to acquire the
     shares of Common Stock subject to the Option, Grantee may not assign its
     rights under the Option except in (i) a widely dispersed public
     distribution, (ii) a private placement in which no one party acquires the
     right to purchase in excess of 2% of the voting shares of Issuer, (iii) an
     assignment to a single party (e.g., a broker or investment banker) for the
     purpose of conducting a widely dispersed public distribution on Grantee's
     behalf or (iv) any other manner approved by the Federal Reserve Board or
     the OTS, as the case may be.

          13.  Filings, Etc.  Each of Grantee and Issuer will use its reasonable
     best efforts to make all filings with, and to obtain consents of, all third
     parties and governmental authorities necessary to the consummation of the
     transactions contemplated by this Agreement, including, without limitation,
     applying to the Federal Reserve Board under the BHCA for approval to
     acquire the shares issuable

                                      C-10
<PAGE>   183

     hereunder, but Grantee shall not be obligated to apply to state banking
     authorities for approval to acquire the shares of Common Stock issuable
     hereunder until such time, if ever, as it deems appropriate to do so.

          14.  Surrender of Option.  (a) Grantee may, at any time following a
     Repurchase Event and prior to the occurrence of an Exercise Termination
     Event (or such later period as provided in Section 10), relinquish the
     Option (together with any Option Shares issued to and then owned by
     Grantee) to Issuer in exchange for a cash fee equal to the Surrender Price.
     The "Surrender Price" shall be equal to $50 million (i) plus, if
     applicable, Grantee's purchase price with respect to any Option Shares and
     (ii) minus, if applicable, the excess of (A) the net price, if any,
     received by Grantee or a Grantee Subsidiary pursuant to the sale of Option
     Shares (or any other securities into which such Option Shares were
     converted or exchanged) to any unaffiliated party, over (B) Grantee's
     purchase price of such Option Shares.

          (b) Grantee may exercise its right to relinquish the Option and any
     Option Shares pursuant to this Section 14 by surrendering to Issuer, at its
     principal office, a copy of this Agreement together with certificates for
     Option Shares, if any, accompanied by a written notice stating (i) that
     Grantee elects to relinquish the Option and Option Shares, if any, in
     accordance with the provisions of this Section 14 and (ii) the Surrender
     Price. The Surrender Price shall be payable in immediately available funds
     on or before the second business day following receipt of such notice by
     Issuer.

          (c) To the extent that Issuer is prohibited under applicable law or
     regulation, or as a consequence of administrative policy, from paying the
     Surrender Price to Grantee in full, Issuer shall immediately so notify
     Grantee and thereafter deliver or cause to be delivered, from time to time,
     to Grantee, the portion of the Surrender Price that it is no longer
     prohibited from paying, within five (5) business days after the date on
     which Issuer is no longer so prohibited; provided, however, that if Issuer
     at any time after delivery of a notice of surrender pursuant to paragraph
     (b) of this Section 14 is prohibited under applicable law or regulation, or
     as a consequence of administrative policy, from paying to Grantee the
     Surrender Price in full, (i) Issuer shall (A) use its reasonable best
     efforts to obtain all required regulatory and legal approvals and to file
     any required notices as promptly as practicable in order to make such
     payments, (B) within five (5) days of the submission or receipt of any
     documents relating to any such regulatory and legal approvals, provide
     Grantee with copies of the same and (c) keep Grantee advised of both the
     status of any such request for regulatory and legal approvals, as well as
     any discussions with any relevant regulatory or other third party
     reasonably related to the same and (ii) Grantee may revoke such notice of
     surrender by delivery of a notice of revocation to Issuer and, upon
     delivery of such notice of revocation, the Exercise Termination Date shall
     be extended to a date six (6) months from the date on which the Exercise
     Termination Date would have occurred if not for the provisions of this
     Section 14(c) (during which period Grantee may exercise any of its rights
     hereunder, including any and all rights pursuant to this Section 14).

          15.  Specific Performance.  The parties hereto acknowledge that
     damages would be an inadequate remedy for a breach of this Agreement by
     either party hereto and that the obligations of the parties hereto shall be
     enforceable by either party hereto through injunctive or other equitable
     relief. In connection therewith, both parties waive the posting of any bond
     or similar requirement.

          16.  Severability.  If any term, provision, covenant or restriction
     contained in this Agreement is held by a court or a federal or state
     regulatory agency of competent jurisdiction to be invalid, void or
     unenforceable, the remainder of the terms, provisions and covenants and
     restrictions contained in 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 agency determines that the Holder is
     not permitted to acquire, or Issuer is not permitted to repurchase pursuant
     to Section 7, the full number of shares of Common Stock provided in Section
     l(a) hereof (as adjusted pursuant to Section l(b) or Section 5 hereof), it
     is the express intention of Issuer to allow the Holder to acquire or to
     require Issuer to repurchase such lesser number of shares as may be
     permissible, without any amendment or modification hereof.

     communications hereunder shall be deemed to have been duly given when
     delivered in person, by fax, telecopy, or by registered or certified mail
     (postage prepaid, return receipt requested) at the respective addresses of

          18.  Governing Law.  This Agreement shall be governed by and construed
     in accordance with the laws of the State of New York.

          19.  Counterparts.  This Agreement may be executed in two or more
     counterparts, each of which shall be deemed to be an original, but all of
     which shall constitute one and the same agreement.

          20.  Expenses.  Except as otherwise expressly provided herein, each of
     the parties hereto shall bear and pay all costs and expenses incurred by it

[CREDIT SUISSE/FIRST BOSTON LETTERHEAD]

February 8, 2000

Board of Directors
Dime Bancorp, Inc.
589 Fifth Avenue
New York, New York 10017

Ladies and Gentlemen:

     You have asked us to advise you with respect to the fairness to the
stockholders of Dime Bancorp, Inc. (the "Company") from a financial point of
view of the consideration to be received by such stockholders pursuant to the
terms of the Agreement and Plan of Merger, dated as of September 15, 1999, as
amended and restated as of December 27, 1999 (the "Merger Agreement"), between
the Company and Hudson United Bancorp ("Hudson"). The Merger Agreement provides
for the merger (the "Merger") of Hudson with and into the Company, with the
Company as the surviving corporation (the "Surviving Corporation"). In the
Merger, each outstanding share of common stock, par value $0.01 per share, of
the Company (the "Dime Common Stock") will be converted into 0.60255 shares (the
"Exchange Ratio") of common stock of the Surviving Corporation, par value $0.01
per share (the "Surviving Corporation Common Stock"). Each outstanding share of
common stock, no par value per share, of Hudson will be converted into one share
of Surviving Corporation Common Stock.

     In arriving at our opinion, we have reviewed certain publicly available
business and financial information relating to the company and Hudson, as well
as the Merger Agreement. We have also reviewed certain other information,
including financial forecasts for 1999, provided to us by the Company and
Hudson, and have met with the Company's and Hudson's management to discuss the
business and prospects of their respective companies.

     We have also considered certain financial and stock market data of the
Company and Hudson, and we have compared those data with similar data for other
publicly held companies in businesses similar to the Company and Hudson and we
have considered the financial terms of certain other business combinations and
other transactions which have recently been effected. We also considered such
other information, financial studies, analyses and investigations and financial,
economic and market criteria which we deemed relevant.

     In connection with our review, we have not assumed any responsibility for
independent verification of any of the foregoing information and have relied on
its being complete and accurate in all material respects. With respect to the
financial forecasts, we have assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
Company's and Hudson's managements as to the future financial performance of the
Company and Hudson and as to the cost savings and other potential synergies
(including the amount, timing and achievability thereof) anticipated to result
from the Merger. In addition, we have not been requested to make, and have not
made, an independent evaluation or appraisal of the assets or liabilities
(contingent or otherwise) of the Company or Hudson, nor have we been furnished
with any such evaluations or appraisals.

     Our opinion is necessarily based upon financial, economic, market and other
conditions as they exist and can be evaluated on the date hereof. We are not
expressing any opinion as to the actual value of the Surviving Corporation
Common Stock when issued to the Company's stockholders pursuant to the Merger or
the prices at which the Surviving Corporation Common Stock will trade subsequent
to the Merger.
<PAGE>   186

     We have acted as financial advisor to the Company in connection with the
Merger and will receive a fee for our services, a significant portion of which
is contingent upon the consummation of the Merger.

     In the past, we have performed certain investment banking services for the
Company and have received customary fees for such services.

     In the ordinary course of our business, we and our affiliates may actively
trade the debt and equity securities of both the Company and Hudson for our and
such affiliates' own accounts and for the accounts of customers and,
accordingly, may at any time hold a long or short position in such securities.

     It is understood that this letter is for the information of the Board of
Directors of the Company in connection with its consideration of the Merger,
does not constitute a recommendation to any stockholder as to how such
stockholder should vote on the Merger.

     Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Exchange Ratio is fair to the stockholders of the Company from
a financial point of view.

Very truly yours,

CREDIT SUISSE FIRST BOSTON CORPORATION

Ladies and Gentleman:

     You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of Common Stock, no par value (the
"Hudson United Stock"), of Hudson United Bancorp ("Hudson United") of the
Exchange Ratio (as defined below) contemplated by the Agreement and Plan of
Merger (the "Agreement"), dated as of September 15, 1999, as amended and
restated as of December 27, 1999, between Hudson United and Dime Bancorp, Inc.
("Dime"). The Agreement provides for the merger of Hudson United and Dime,
pursuant to which, among other things, each share of Hudson United Stock will be
exchanged for one share (the "Exchange Ratio") of Common Stock, par value $0.01
per share (the "Dime Stock"), of Dime and each share of Dime Stock will be
converted into 0.60255 shares of Common Stock, par value $0.01 per share, of
Dime, the surviving company.

     Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. We are
familiar with Hudson United having provided certain financial advice from time
to time, including having provided Hudson United a fairness opinion in
connection with the acquisition of Lafayette American Bank and Trust Company in
July 1986 and in connection with the acquisition of JeffBanks, Inc. in June 1999
and having acted as financial advisor in connection with, and having
participated in certain of the negotiations leading to, the Agreement. We also
have provided certain investment banking services to Dime from time to time,
including having acted as a co-manager of the public offering of the $150
million aggregate principal amount of 7% Notes due 2001 in July 1999. Goldman,
Sachs & Co. provides a full range of financial advisory and securities services
and, in the course of its normal trading activities, may from time to time
effect transactions and hold securities, including derivative securities, of
Hudson United or Dime for its own account and for the accounts of customers.

     In connection with this opinion, we have reviewed, among other things, the
Agreement; the Registration Statement on Form S-4 of Dime dated February 8,
2000, including the joint proxy statement-prospectus relating to the special
meetings of Dime and Hudson United stockholders being held to vote on the
merger; Annual Reports to Stockholders and Annual Reports on Form 10-K of Hudson
United and Dime for the five years ended December 31, 1998; certain interim
reports to stockholders and Quarterly Reports on Form 10-Q of Hudson United and
Dime; certain other communications from Hudson United and Dime to their
respective stockholders; certain internal financial analyses and forecasts for
Hudson United and Dime prepared by their respective managements; and certain
cost savings and operating synergies projected by the management of Hudson
United to result from the transaction contemplated by the Agreement (the
"Synergies"). We also have held discussions with members of the senior
management of Hudson United and Dime regarding the strategic rationale for, and
the potential benefits of, the transaction contemplated by the Agreement and the
past and current business operations, financial condition and future prospects
of their respective companies. In addition, we have reviewed the reported price
and trading activity for the Hudson United Stock and the Dime Stock, compared
certain financial and stock market information for
<PAGE>   188
Hudson United Bancorp

Page  2

Hudson United and Dime with similar information for certain other companies the
securities of which are publicly traded, reviewed the financial terms of certain
recent business combinations in the commercial banking industry and in other
industries generally and performed such other studies and analyses as we
considered appropriate.

     We have relied upon the accuracy and completeness of all of the financial
and other information reviewed by us and have assumed such accuracy and
completeness for purposes of rendering this opinion. In that regard, we have
assumed with your consent that the Synergies have been reasonably prepared on a
basis reflecting the best currently available estimates and judgments of Hudson
United. For purposes of our analysis with respect to forecasts of future
performance we have relied at your instruction on the estimates for Hudson
United and Dime published by the Institutional Brokers Estimate Service. We are
not experts in the evaluation of loan and lease portfolios for purposes of
assessing the adequacy of the allowances for losses with respect thereto and
have assumed, with your consent, that such allowances for each of Hudson United
and Dime are in the aggregate adequate to cover all such losses. In addition, we
have not reviewed individual credit files nor have we made an independent
evaluation or appraisal of the assets and liabilities (including any hedge or
derivative positions) of Hudson United or Dime or any of their subsidiaries and
we have not been furnished with any such evaluation or appraisal. We have also
assumed with your consent that the transaction contemplated by the Agreement
will be accounted for as a pooling-of-interests under generally accepted
accounting principles. We also have assumed that all material governmental,
regulatory or other consents and approvals necessary for the consummation of the
transaction contemplated by the Agreement will be obtained without any adverse
effect on Hudson United or Dime or on the contemplated benefits of the
transaction contemplated by the Agreement. Our advisory services and the opinion
expressed herein are provided for the information and assistance of the Board of
Directors of Hudson United in connection with its consideration of the
transaction contemplated by the Agreement and such opinion does not constitute a
recommendation as to how any holder of Hudson United Stock should vote with
respect to such transaction.

     Based upon and subject to the foregoing and based upon such other matters
as we consider relevant, it is our opinion that as of the date hereof the
Exchange Ratio pursuant to the Agreement is fair from a financial point of view
to the holders of the Hudson United Stock.

                                          Very truly yours,

                                    PART II

              ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling the
registrant pursuant to the foregoing provisions, the registrant has been
informed that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is
therefore unenforceable.

     The description below is equally applicable to Dime currently.

     Dime United's certificate of incorporation will provide that Dime United's
directors will not be personally liable to Dime United or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for

- - any breach of the director's duty of loyalty to Dime United or its
  stockholders,

- - acts or omissions not in good faith or which involve intentional misconduct or
  knowing violation of law,

- - unlawful dividends or distributions, or

- - any transaction from which the director derived an improper personal benefit.

     Dime United's certificate of incorporation will further provide that, if
Delaware law is amended to further eliminate or limit the personal liability of
directors, then the liability of a director of Dime United will be eliminated or
limited to the fullest extent permitted by Delaware law. Delaware law provides
that, subject to certain limitations in the case of suits brought by a
corporation and derivative suits brought by a corporation's stockholders in its
name, a corporation may indemnify any person who is made a party to any third
party suit or proceeding on account of being a director, officer, employee or
agent of the corporation against expenses, including attorney's fees, judgments,
fines and amounts paid in settlement reasonably incurred by him in connection
with the action, through, among other things, a majority vote of the directors
who were not parties to the suit or proceeding, if the 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

- - in a criminal proceeding, had no reasonable cause to believe his conduct was
  unlawful.

     Dime United's certificate of incorporation will provide that:

- - in actions other than by or in the right of the corporation, Dime United will,
  to the extent permitted by applicable banking law or regulation, indemnify any
  person who was or is a party or is threatened to be made a party to any action
  because that person is or was or agreed to be a director or officer of Dime
  United, or is or was serving or agreed to serve at the request of Dime United
  as a director, officer, partner, trustee, administrator or fiduciary of
  another entity, against any costs, expenses, judgments, fines and amounts paid
  in settlement, if that person acted in good faith and in a manner that person
  reasonably believed to be in, or not opposed to, the best interests of Dime
  United, and, with respect to any criminal action or proceeding, had no
  reasonable cause to believe his or her conduct was unlawful. Expenses may be
  advanced to these persons on the condition that they will be repaid if the
  person is not entitled to be indemnified.

- - in actions by or in the right of the corporation, Dime United will, to the
  extent permitted by applicable banking law or regulation, indemnify any person
  who was or is a party or is threatened to be made a party to any action by or
  in the right of Dime United to procure a judgment in its favor because that
  person is or was or has agreed to become a director or officer of Dime United,
  or is or was serving or has agreed to serve at the request of Dime United as a
  director, officer, partner, trustee, administrator or fiduciary of another
  entity, against expenses actually and reasonably incurred by that person in
  the defense or settlement of such action, if he or she acted in good faith and
  in a manner that person reasonably believed to be in, or not opposed to, the
  best interest of Dime United, except that no indemnification shall be made in
  respect to any claim, issue or matter as to which such person shall
<PAGE>   190

  have been adjudged to be liable to Dime United unless and only to the extent
  that the court in which such action was brought determines that such person is
  fairly and reasonably entitled to indemnity for such expenses which the court
  shall deem proper. Expenses may be advanced to these persons on the condition
  that they will be repaid if the person is not entitled to be indemnified.

- - to the extent that a director or officer of Dime United has been successful in
  defense of any action, that person must be indemnified against all expenses
  actually and reasonably incurred by that person.

- - Dime United may, but is not required to, indemnify and advance expenses to an
  employee or agent of Dime United in defense of any action by reason of the
  fact that such person is or was or has agreed to become an employee or agent
  of Dime United, or is of was serving or has agreed to serve at the request of
  Dime United as an employee or agent of another entity, against all costs
  actually and reasonably incurred by that person.

          (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 the 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 not more than a 20 percent change in the maximum offering
     price set forth in the "Calculation of Registration Fee" table in the
     effective registration statement.

          (iii) 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;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
Registration Statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Securities and
Exchange Commission by the registrant pursuant to Section 13 or 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference 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 here, 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.

                                      II-3

     (b) The undersigned registrant hereby undertakes that, 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, where applicable, 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 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.

     (c)(1) The undersigned registrant hereby undertakes as follows: 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

for by the other items of the applicable form.

     (2) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (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 145, 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 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) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the proxy statement 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) The undersigned registrant hereby undertakes 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.

                      [LETTERHEAD OF SULLIVAN & CROMWELL]

                                                                February 7, 2000

Dime Bancorp, Inc.,
     589 Fifth Avenue,
          New York, New York 10017.

Ladies and Gentlemen:

     In connection with the registration under the Securities Act of 1933 (the
"Act") of 54,366,259 shares (the "Securities") of Common Stock, par value $0.01
per share, of Dime Bancorp, Inc., a Delaware corporation (the "Company"), and
the related preferred stock purchase rights (the "Rights") to be issued pursuant
to the Stockholder Protection Rights Agreement, dated as of October 20, 1995
(the "Rights Agreement"), between the Company and First National Bank of Boston,
as Rights Agent, issuable under the Agreement and Plan of Merger, dated as of
September 15, 1999 and amended and restated on December 27, 1999, (the "Merger
Agreement"), between Hudson United Bancorp and the Company, we, as your counsel,
have examined such corporate records, certificates and other documents, and such
questions of law, as we have considered necessary or appropriate for the
purposes of this opinion. Upon the basis of such examination, we advise you
that, in our opinion:

          (1) When the registration statement relating to the Securities and the
     Rights (the "Registration Statement") has become effective under the Act
     and the Securities to be issued under the Merger Agreement have been duly
     issued and delivered as contemplated by the Registration Statement, the
     Securities will be validly issued, fully paid and nonassessable.

          (2) When the Registration Statement has become effective under the Act
     and the Securities have been validly issued and delivered as contemplated
     by the Registration Statement, the Rights attributable to the Securities
     will be validly issued.

     In connection with our opinion set forth in paragraph (2) above, we note
that the question whether the Board of Directors of the Company might be
required to redeem the Rights at some future time will depend upon the facts and
circumstances existing at that time and, accordingly, is beyond the scope of
such opinion.

     The foregoing opinion is limited to the Federal laws of the United States
and the laws of the State of Delaware, and we are expressing no opinion as to
the effect of the laws of any other jurisdiction.

     We have relied as to certain matters on information obtained from public
officials, officers and counsel for the Company and other sources believed by us
to be responsible.

     We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the heading "Validity of
Dime United Common Stock" in the Proxy Statement/ Prospectus included in the
Registration Statement. In giving such consent, we do not thereby admit that we
are in the category of persons whose consent is required under Section 7 of the
Act.

                                          Very truly yours,

                                          /s/ SULLIVAN & CROMWELL

<PAGE>   1

                                                                     EXHIBIT 8.1

                      [LETTERHEAD OF SULLIVAN & CROMWELL]

                                                                February 7, 2000

Dime Bancorp, Inc.,
     589 Fifth Avenue,
          New York, New York 10017.

Ladies and Gentlemen:

        We have acted as counsel to Dime Bancorp, Inc., a Delaware corporation
(the "Company"), in connection with the planned merger of Hudson United Bancorp,
a New Jersey corporation ("Hudson"), with and into the Company, pursuant to the
Agreement and Plan of Merger, dated as of September 15, 1999 and amended and
restated on December 27, 1999, by and between Hudson and the Company (the
"Merger Agreement"). All capitalized terms used and not otherwise defined herein
shall have the meanings assigned to such terms in the Merger Agreement.

        For purposes of this opinion, we have reviewed the Merger Agreement and
such other documents and matters of law and fact as we have considered necessary
or appropriate, and we have assumed, with your consent, the following:

          (1) The Merger will be completed in the manner set forth in the Merger
     Agreement and the Joint Proxy Statement/Prospectus of the Company and
     Hudson relating thereto (the "Proxy/ Prospectus"); and

          (2) The facts specified in the letters of representation from the
     Company and Hudson to us, both dated January 21, 2000, were true and
     complete when made and will be true and complete at the Effective Time.

        On the basis of the foregoing and subject to the limitations described
below, it is our opinion that (i) the Merger will be treated as a
"reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code, (ii) no income, gain or loss will be recognized by the Company or Hudson
pursuant to the Merger and (iii) a stockholder of the Company or Hudson who
receives solely Surviving Corporation Common Stock in exchange for its shares of
Company stock or Hudson stock in the Merger will not recognize any income, gain
or loss, except with respect to cash received by a stockholder of the Company
instead of fractional shares of Surviving Corporation Common Stock.

        This opinion may not be applicable to particular classes of taxpayers,
such as financial institutions, insurance companies, tax-exempt organizations,
broker-dealers, traders in securities that elect to apply a mark-to-market
method of accounting, persons that hold Company stock or Hudson stock as part of
a hedge, straddle or conversion transaction, persons who are not citizens or
residents of the United States and stockholders who acquired their shares of
Company stock or Hudson stock through the exercise of an employee stock option
or otherwise as compensation. This opinion is limited to the federal income tax
laws of the United States and does not purport to discuss the consequences of
effectiveness of the Merger under any other laws.

        Finally, in connection with the foregoing, we express no opinion as to
the effect, if any, on Hudson of the early termination of its taxable year as of
the Effective Date (assuming such Date is not otherwise the end of its taxable
year) in respect of 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.

        We hereby consent to the filing of this opinion as our exhibit to the
Registration Statement containing the Proxy/Prospectus and all amendments
thereto and the references to us under the heading "Federal Income Tax
Consequences of the Merger" in the Proxy/Prospectus. In giving such consent, we
do not thereby admit that we are in the category of persons whose consent is
required under Section 7 of the Securities Act.

                                          Very truly yours,

                                          /s/ SULLIVAN & CROMWELL

     Re: Merger of Hudson United Bancorp and Dime Bancorp, Inc.

Gentlemen:

     We have represented Hudson United Bancorp ("HUB"), a New Jersey corporation
which is a registered bank holding company in connection with the merger of HUB
into Dime Bancorp, Inc. ("DIME"), a Delaware Corporation (the "Merger"). The
Merger shall be effected pursuant to the provisions of an Agreement and Plan of
Merger dated as of September 15, 1999, as amended and restated on December 27,
1999, (the "Merger Agreement") between HUB and DIME.

     Capitalized terms used but not defined herein shall have the meanings
ascribed to such terms in the Joint Proxy Statement-Prospectus pertaining to the
Merger.

     We have assumed, with your consent, that:

     (a) the Merger will be effected in accordance with the Merger Agreement,
and

     (b) the factual representations contained in the letters of representation
from HUB and DIME dated January 21, 2000 will be true at the Effective Time;
provided, however, that we did not rely on legal conclusions, if any, contained
in such representations.

     On the basis of the foregoing, and our consideration of such other matters
of fact and law as we have deemed necessary or appropriate, it is our opinion,
under presently applicable federal income tax law that:

     1. The Merger will qualify as a "reorganization" under Section 368. (All
"Section" references are to the Internal Revenue Code of 1986, as amended unless
otherwise noted.)

     2. No gain or loss will be recognized by HUB or DIME in connection with the
Merger. Sections 361(a) and 1032.

     3. DIME and HUB are each "parties to the reorganization" within the meaning
of Section 368(b).

     4. HUB shareholders will not recognize any gain or loss for federal income
tax purposes upon the exchange in the Merger of shares of HUB Common Stock
solely for DIME Common Stock. Section 354(a).

     5. DIME shareholders will not recognize any gain or loss for federal income
tax purposes upon the exchange in the Merger of Shares of DIME Common Stock
solely for DIME Common Stock. Section 354(a).

     6. HUB and DIME shareholders receiving cash in lieu of fractional shares of
DIME Common Stock will be treated as if such fractional shares had been received
from DIME and then subsequently redeemed by DIME. The cash received by the HUB
and DIME shareholders in lieu of fractional shares will be treated as having
been received as full payment in exchange for the fractional shares deemed to
have been redeemed. Section 302(a). Accordingly, such shareholders should, in
general, recognize capital gain or loss
<PAGE>   2

in an amount equal to the difference between the amount of such cash received
and the portion of the adjusted tax basis in the DIME Common Stock allocable to
the fractional share interest.

     The opinions expressed herein are delivered to you solely in connection
with and for the purposes of the transactions contemplated by the Merger
Agreement. We consent to the filing with the SEC of this letter as an exhibit to
the Registration Statement on Form S-4 of which the Proxy Statement is a part,
and to the reference to our firm under the heading "Federal Income Tax
Consequences" contained therein. In giving such consent, we do not admit that we
are in the category of persons whose consent is required under Section 7 of the
Securities Act of 1933 or the rules of the SEC thereunder.

                                          Very truly yours,

                                          /s/  Pitney, Hardin, Kipp & Szuch LLP

     second anniversary of the date of grant (provided the Officer continues to
     hold such offices on such date); and (iii) one-third on December 30, 2002

     such stock option is granted), upon vesting, remain exercisable for the
     full term thereof, without reduction of such term on account of termination
     of employment (other than for cause), retirement, disability or death (or
     any other events, such as loss of office, that are directly related
     thereto) (each, a "Termination Event"), provided, that such options shall

     the applicable grant letter.

           (ii) At the Effective Time, each stock option for Company stock
     (including any tandem stock appreciation right) granted to the Officer
     prior to the Effective Time (other than stock options to which Section
     5(g)(i) hereof apply) shall, upon vesting, to the extent permitted by the
     plan under which such stock option was granted but notwithstanding anything
     to the contrary in the grant letter related to such stock option,
     thereafter remain exercisable for the term specified in such grant letter
     without reduction of such term on account of any Termination Event, but
     otherwise subject to all of the other terms and conditions of such
     applicable grant letter."

     6. Section 7 of the Employment Agreement shall be amended as follows:

          (a) The existing provisions of Section 7 shall be retained and shall
     be designated paragraph (a) thereof;

          (b) By deleting the figure "50%" in the first sentence of such Section

          (c) There shall be added thereto the following Section 7(b):

             "(b) Notwithstanding anything in paragraph (a) of this Section 7 to
        the contrary, the Company shall pay to the Officer, for each calendar
        year or portion thereof during the Officer's remaining life following
        the later of the date the Officer attains age 65, or the date his
        employment by the Company and the Bank terminates, an amount equal to
        the difference, if any, between (i) $1,235,000 (prorated for any
        applicable periods of less than one year) less (ii) the sum of (A) all
        benefits payable to the Officer under the SERP with respect to such year
        or

                                        2
<PAGE>   3

        period or otherwise pursuant to Section 7(a), presuming an effective
        election to commence SERP benefits (or other benefits pursuant to
        Section 7(a)) at the same time as benefits under this paragraph (b) had
        been made (whether or not such SERP (or other Section 7(a)) benefits are
        actually being paid on such date), plus (B) the amount of any benefits
        which the Officer is entitled to receive for such year or period under
        any defined benefit plan qualified under Section 401(a) of the Code
        sponsored by the Company, any Affiliate (as defined in Section 12(a)) or
        any predecessor or successor to any of them (the "Retirement Plans")
        plus (C) the amount of any benefits which the Officer is entitled to
        receive for such year or period under any defined benefit excess benefit
        or benefit restoration plan of the Company, any Affiliate or any
        predecessor or successor to any of them, plus (D) the amount of any
        benefits which the Officer is entitled to receive for such year or
        period under any other plan, agreement or arrangement maintained by the
        Company, any Affiliate or any predecessor or successor to any of them
        that determines benefit amounts with relation to one or more Retirement
        Plans, plus (E) the amount of any benefits which the Officer is then
        entitled to receive for such year (or, if the amount specified in clause
        (i) is to be prorated for a specified period, for the same period) under
        Section 6 of this Agreement. In determining the amount so payable, any
        benefits described in clause (ii) of the preceding sentence (other than
        subclause (E) thereof) that are not payable in the form of a single life
        annuity commencing at the same time as benefits hereunder shall, solely
        for purposes of the preceding sentence, be converted, on an actuarial
        equivalent basis, to a single life annuity form of payment commencing on
        the same date as the benefits pursuant to this paragraph (b) with
        actuarial equivalence to be determined based on the factors used to
        determine actuarial equivalence under the SERP. The amount so determined
        to be payable pursuant to this paragraph (b) shall be paid on the same
        basis as payments under the SERP (including actuarial reductions with
        respect to alternative forms of benefit thereunder, and the SERP's
        provisions regarding preretirement survivor benefits), and the Officer
        shall have the same election rights with respect thereto, regardless of
        whether or not any amounts are then being paid under the SERP."

     7. Section 9(e) shall be amended to delete the existing text thereof in its
entirety and insert in its place the following:

          "Unless this Agreement shall have previously been terminated pursuant
     to the terms hereof, then upon the expiration of the Term on December 31,
     2002, the employment of the Officer hereunder shall terminate and the
     Officer shall not be entitled to any additional compensation or benefits as
     a result of such expiration pursuant to this Section 9 or Section 12."

     8. Section 12(g)(i) shall be amended so that each reference therein to
"SERP benefits" shall be changed to read "SERP and other related benefits."

     9. Section 16 shall be amended by adding the following at the end thereof:
"This Agreement shall be subject to, and the Officer shall be entitled to the
benefits of, the applicable provisions of Sections 3.3 and 3.4 of the Merger
Agreement."

     10. In consideration of the rights and benefits granted under this
Amendment, the Officer hereby irrevocably waives any right he may otherwise to
additional benefits based on a claim that the provisions of Section 2 of this
Amendment or the effectuation thereof constitute or will constitute a "Material
Change" as defined in and for purposes of the Employment Agreement.

                                        3

     11. The Company hereby joins in this Amendment for purposes of confirming
that the Agreement dated as of January 30, 1998 between the Company and the
Officer shall, as modified hereby, remain in full force and effect and that each
reference therein to the "Employment Agreement" shall be deemed to mean the
Employment Agreement as modified and amended by this Amendment.

illness and vacation), substantially all of the Officer's business time,
attention, skill and efforts shall be devoted to the performance of the
Officer's duties under this Agreement. Notwithstanding the foregoing, the
Officer may (a) continue to serve on the boards of directors of, and hold any
other offices or positions in, companies or organizations previously approved by
the Board of Directors of the Company and (b) with the approval of the Board of
Directors of the Company, from time to time serve on the board of directors of,

prior to the Effective Time may provide the Officer with a normal increase in
annual salary, and may continue all existing bonus, incentive and employee
benefit arrangements, including, without limitation, the making of normal stock
option and restricted stock plan grants, on a basis consistent with past
practice. In no event shall the Officer's annual salary be decreased below his
annual salary specified in the first sentence of this Section 5(a) plus all
subsequent increases in his annual salary. As used in this Agreement, "annual
salary" shall mean, at any time, the annual rate of salary then payable to the
Officer pursuant to this Section 5(a) (before deduction of any amounts deferred
under any deferred compensation plan of the Company or the Bank, any voluntary
contributions to a 401(k) plan of the Company or the Bank, or any other
deductions from income) and shall be exclusive of bonuses, incentive
compensation or other compensation or benefits paid to or accrued for the
Officer other than pursuant to this Section 5(a). Amounts payable to the Officer
under this Section 5(a) shall, subject to the provisions of Section 5(e), be
payable in installments (pro rata with respect to the period during a year to
which it relates) in accordance with the prevailing general payroll practice of
the Company as it may exist from time to time.

other provider agreed to by the Company and the Officer) in an amount not to
exceed $12,000 per annum.

     (c) The Officer shall not have or acquire by virtue of this Agreement any
rights to participate in, or receive benefits with respect to, any compensation
or benefit plan or program of the Company or the Bank, except (i) that during
the Post-Merger Period and while employed by the Company, the Officer shall
(subject to the approval of the Compensation Committee or other appropriate
committee of the Board of Directors) participate in the Company's Senior Officer
Incentive Plan, as in effect from time to time, with a target bonus (the "Target
Bonus") of at least 100% of the Officer's then effective annual salary (or such
higher target bonus amount as the Board of Directors of the Company may
establish from time to time), (ii) during the Initial Post-Merger Period and
while employed by the Company, the Officer shall (at the discretion of the
Compensation Committee and the Board of Directors or other appropriate committee
of the Board of Directors) receive annual stock incentive awards at the same
time as and equal to 80% of the base annual stock incentive award of the Present
CEO for such year, and during the Remaining Post-Merger Period and while
employed by the Company, the Officer shall receive annual stock incentive awards
(at the discretion of the Compensation Committee and the Board of Directors or
other appropriate committee of the Board of Directors) on a basis commensurate
with the awards for which the Present CEO was eligible during the Initial
Post-Merger Period; (iii) that while employed by the Company, the Officer may
participate in plans or programs of the Company and the Bank to the extent
provided in such plans and programs and on the same basis as if the Officer's
employment were not subject to the terms and conditions of this Agreement;
provided that, during the Initial Post-Merger Period, the Officer shall, subject
to the terms thereof, be eligible to participate in all plans and programs in
which the Present CEO is eligible to participate and shall be considered for any
awards that may be made thereunder at the same time as the Present CEO, or (iv)
as otherwise specifically provided in this Agreement, including without
limitation Section 7 hereof. For purposes of this Section 5(c), it is the
intention of the parties that the Officer's bonus opportunity and all other
grant opportunities under this Agreement shall at all times during the Initial
Post-Merger Period be: (i) at least 80% (in dollar value) of the Present CEO's
bonus and other grant opportunities; (ii) awarded on the same terms and
conditions as awards to the Present CEO regarding exercise price, pre- and
post-termination exercise rights, vesting and term, and (iii) to the extent the
Officer's opportunities are based on corporate-wide performance goals, subject
to the same corporate-wide performance goals as apply to the opportunities
provided to the Present CEO.

     (d) The Officer is authorized to incur reasonable expenses for promoting
the businesses of the Company and its Affiliates, including expenses for travel,
entertainment and similar items. The Company shall pay, or reimburse the Officer
for, all such expenses upon presentation by the Officer from time to time of an
itemized account (in reasonable detail) of such expenditures.

     (e) Notwithstanding anything to the contrary in the foregoing provisions,
following the Effective Time the payment (but not the grant or award) of any
amounts that would otherwise be payable to the Officer but which would be in
excess of the amount which the Company or the Bank could deduct for federal
income tax purposes if then paid on account of the operation of Section 162(m)
of the Internal Revenue Code of 1986, as amended (the "Code"), shall be deferred
to the extent such deferral is required pursuant to a policy adopted by the
Compensation Committee of the Company or the Bank and, to the extent so
deferred, shall be payable pursuant to the relevant terms of the Company's
Voluntary Deferred Compensation Plan; provided, however, that, if a Change in
Control (as defined in Section 12(a)) has occurred, deferral of amounts payable
hereunder to the Officer on or after the date of such Change in Control will
only be required if and to the extent such policy in effect immediately prior to
the Change in

                                        3
<PAGE>   4

Control (without taking into consideration any changes therein made in
contemplation of the occurrence of the Change in Control) requires or would have
required such deferral.

     (f) The Company and the Bank may from time to time enter into arrangements
for the sharing of costs and provision of benefits to the Officer hereunder;
provided, that each of the Company and the Bank shall remain jointly and
severally liable for fulfillment of all obligations hereunder; provided,
further, that any compensation, benefits, reimbursements or other payments made
to the Officer, whether paid by the Company or the Bank (or any other Affiliate
of the Company) shall be deemed made and received in satisfaction of the
Company's and the Bank's obligations hereunder, regardless of whether an
obligation is herein stated to be an obligation of the Company only or of the
Bank only; and provided further, that where any notice is required or permitted,
to be given or action taken by the Company or the Bank, such condition shall be
deemed fulfilled if such notice is given or action taken by either of the
Company or the Bank.

     (g) Immediately following the Effective Time, subject to the discretion and
approval of the Compensation Committee, the Board of Directors or other
appropriate Committee of the Board of Directors, the Company shall grant to the
Officer options to purchase 120,000 shares of the Company's common stock at the
market price thereof on such date; provided, that such options shall vest in
accordance with the following schedule: (i) one-third on the date on which the
Officer becomes Chairman of the Board and Chief Executive Officer of the
Company; (ii) one-third on the first anniversary of the date described in clause
(i) (provided the Officer continues to hold such offices on such anniversary
date); and (iii) one-third on December 31, 2004 (provided the Officer continues
to hold such offices on such anniversary date). Such options shall be granted
subject to the terms and conditions (including accelerated vesting) of the
Company's stock incentive plan under which they are issued, and such other terms
as are set by the granting committee in accordance with such Plan.

     (h) Immediately following the Effective Time, subject to the discretion and
approval of the Compensation Committee, the Board of Directors or other
appropriate Committee of the Board of Directors, the Company shall offer to sell
to the Officer 100,000 shares of common stock of the Company subject to vesting
restrictions ("Restricted Stock") at a price equal to the par value of such
shares, with the grant of such shares to vest, and the restrictions on such
stock (if so purchased) to lapse in accordance with the following schedule:

             (i) one-third on the first anniversary of the date of grant
        (provided the Officer continues to be employed hereunder on such date);
        (ii) one-third on the second anniversary of the date of grant (provided
        the Officer continues to be employed hereunder on such date); and (iii)
        one-third on the third anniversary of the date of grant (provided the
        Officer continues to be employed hereunder on such date). The Restricted
        Stock shall be granted subject to the terms and conditions (including
        accelerated vesting) of the Company's stock incentive plan under which
        it is issued, and such other terms as are set by the granting committee
        in accordance with such plan.

     6.  Disability.  (a) The Company may terminate the Officer's employment
under this Agreement for "permanent disability" if (i) the Officer shall become
physically or mentally disabled or incapacitated to the extent that the Officer
has been absent from the Officer's duties with the Company on account of such
disabilities or incapacitation, as determined in a manner consistent with the
policy which applies generally to employees of the Company, on a full-time basis
for a period of six consecutive months, and (ii) within 30 days after written
notice of proposed termination for permanent disability is given by the Company
to the Officer, the Officer shall not have returned to full-time performance of
the Officer's duties.

     (b) In the event of termination for "permanent disability" following the
Effective Time, the Company shall provide the Officer with a benefit equal to
(i) his annual salary (as in effect immediately prior to the occurrence of such
disability) for a period commencing on the Effective Date of Termination and
ending on the day immediately prior to the first anniversary thereof and (ii)
75% of his annual salary (as in effect immediately prior to the occurrence of
such disability) from the date of the first anniversary of the Effective Date of
Termination and continuing through the duration of his disability (but in no
event beyond the Officer's attainment of age 65). Notwithstanding the first
sentence of this Section 6(b), any

                                        4
<PAGE>   5

such payment shall terminate upon the earliest to occur of (A) the date the
Officer returns to full-time employment with the Company, (B) the date of the
Officer's full time employment by another employer (including full-time service
as a sole proprietor or owner of an unincorporated business), or (C) the date of
the Officer's death. In the event of termination for "permanent disability," the
Company also shall continue to provide until the Officer's death or, if earlier,
the first to occur of (aa) the date the Officer returns to full-time employment
with the Company, (bb) the date of the Officer's full-time employment by another
employer, or (cc) the date of the Officer's attainment of age 65, all life,
medical and dental insurance coverage as is maintained by the Company for
full-time employees, provided that the Officer shall continue to pay all amounts
in respect of such coverage that other employees receiving the same level of
coverage are required to pay. In the event of termination for "permanent
disability" following the Effective Time, the Company shall also provide the
Officer with the benefits set forth in Section 12(d)(ii) hereof (notwithstanding
that no Change in Control shall have occurred).

     (c) There shall be no reduction in the compensation payable to the Officer
or the Officer's other rights under this Agreement during any period when the
Officer is incapable of performing some or all of the Officer's duties by reason
of temporary or partial disability.

     (d) The obligations of the Company to provide the benefits described in
Section 6(b) may be satisfied, in whole or in part, by payments under disability
insurance policies covering the Officer and obtained and maintained in force
(with respect to the benefit described in the first sentence of Section 6(b)
solely at the Company's expense) by the Company. In connection therewith, the
Company may require the Officer to elect the maximum disability insurance
coverage available under the Bank's or the Company's group disability policy,
provided that the Company shall pay on the Officer's behalf all amounts required
to be paid by the Officer as a result of such election. The Officer shall
cooperate with the Company in all reasonable ways to obtain any such disability
or key person insurance coverage.

     7.  Supplemental Executive Retirement Benefits.  (a) During the Post-Merger
Period, the Officer shall participate in the Supplemental Executive Retirement
Plan of the Company (the "SERP") and shall have a "Pension Goal" under such plan
of not less than 50%. The Company acknowledges that in light of the Officer's
years of service with the Company, he will following the Effective Time be fully
vested in the Surviving Corporation's SERP. For purposes of calculating benefits
payable to the Officer under the SERP, any benefit plans, programs or
arrangements of the Company or any predecessor or Affiliate of the Company that
are in effect prior to the Effective Time shall be treated under the SERP in the
same manner as plans of the Surviving Corporation, but no amount of gross up tax
payments made pursuant to Section 12(g) hereof or otherwise shall be considered
"Compensation" thereunder.

     (b) Notwithstanding anything in paragraph (a) of this Section 7 to the
contrary, if the Officer's employment hereunder is terminated by the Company for
any reason (other than a termination by the Company for "cause"), or the Officer
terminates his employment hereunder at any time after a Material Change has
occurred (determined without regard to whether or not a Change in Control has
occurred), at any time during the Term following the Effective Time, then the
Company shall pay to the Officer, for each calendar year or portion thereof
during the Officer's remaining life following the later of the Effective Date of
Termination or the date the Officer attains age 55, an amount equal to the
difference, if any, between (i) $741,000 (prorated for any applicable periods of
less than one year) less (ii) the sum of (A) all benefits payable to the Officer
under the SERP with respect to such year or period, presuming an effective
election to commence SERP benefits at the same time as benefits under this
paragraph (b) had been made (whether or not such SERP benefits are actually
being paid on such date), plus (B) the amount of any benefits which the Officer
is entitled to receive for such year or period under any defined benefit plan
qualified under Section 401(a) of the Code sponsored by the Company, any
Affiliate (as defined in Section 12(a)) or any predecessor or successor to any
of them (the "Retirement Plans") plus (C) the amount of any benefits which the
Officer is entitled to receive for such year or period under any defined benefit
excess benefit or benefit restoration plan of the Company, any Affiliate or any
predecessor or successor to any of them, plus (D) the amount of any benefits
which the Officer is entitled to receive for such year or period under any other
plan, agreement or arrangement maintained by the Company, any Affiliate or any
predecessor or successor to any of them that determines benefit amounts with
relation to
                                        5
<PAGE>   6

one or more Retirement Plans, plus (E) the amount of any benefits which the
Officer is then entitled to receive for such year (or, if the amount specified
in clause (i) is to be prorated for a specified period, for the same period)
under Section 6 of this Agreement. In determining the amount so payable, any
benefits described in clause (ii) of the preceding sentence (other than
subclause (E) thereof) that are not payable in the form of a single life annuity
commencing at the same time as benefits hereunder shall, solely for purposes of
the preceding sentence, be converted, on an actuarial equivalent basis, to a
single life annuity form of payment commencing on the same date as the benefits
pursuant to this paragraph (b) with actuarial equivalence to be determined based
on the factors used to determine actuarial equivalence under the SERP. The
amount so determined to be payable pursuant to this paragraph (b) shall be paid
on the same basis as payments under the SERP (including actuarial reductions
with respect to alternative forms of benefit thereunder, and the SERP's
provisions regarding preretirement survivor benefits), and the Officer shall
have the same election rights with respect thereto, regardless of whether or not
any amounts are then being paid under the SERP.

     8.  Death.  In the event of the Officer's death during the Term, this
Agreement and all of the Company's obligations under this Agreement shall
terminate (except as otherwise provided in this Section 8, Section 12(f) or with
respect to the obligations of the Company under Section 7). In the event of the
Officer's death during the Term, the Company or the Bank shall, during the
remainder of the life of the Officer's surviving spouse, continue to provide
such spouse the same level of medical and dental insurance as is maintained from
time to time by the Company or the Bank for spouses of full-time employees (or,
as appropriate, retirees) of the Company or the Bank or, in lieu of providing
any such coverage, the Company or the Bank may pay such spouse the cash
equivalent of the cost of such coverage), provided that such surviving spouse
shall continue to pay any amounts in respect of such coverage that is otherwise
required to be paid by employees (or, as appropriate, retirees) for such
coverage and provided, further, that any such medical coverage may be modified
so that Medicare (or other governmental) coverage is primary, with coverage
provided by the Company or the Bank supplementary, to the extent permitted by
law. In the event of the Officer's death during the Term, the Company shall
provide the Officer's beneficiaries with the benefits set forth in Section
12(d)(ii) hereof (notwithstanding that no Change in Control shall have
occurred).

     9.  Termination by the Company.  (a)(i) The Company may terminate the
Officer's employment under this Agreement at any time by giving the Officer
written notice of such termination, provided that, except where termination is
for "cause" (as defined in Section 9(b)), such notice shall be provided at least
30 days prior to the Effective Date of Termination. In the event of a
termination by the Company of the Officer's employment, other than a termination
for "cause" (as defined in Section 9(b)), then except as otherwise provided in
this Section 9 and in Sections 2(b), 7 and 12 hereof, all of the Company's
obligations under this Agreement shall terminate, except that the Officer shall
remain entitled to any compensation or benefits earned prior to the Effective
Date of Termination and shall not be precluded from receiving a bonus as
provided in Section 5(c) hereof as a result of his termination of employment
prior to the payment date for such bonus and except that the Company shall
(subject to the provisions of Section 9(c)): (A) pay to the Officer, as a
severance payment for services previously rendered to the Company and the Bank,
a lump sum equal to the sum of (1) the Officer's annual salary (as defined in
Section 5(a)) at the Effective Date of Termination plus (2) the amount of the
target bonus which the officer is eligible to earn for the year in which the
Effective Date of Termination occurs and (B) provide the Officer with the
benefits set forth in Section 12(d)(ii) hereof (notwithstanding that no Change
in Control shall have occurred) and (C) maintain, until the later to occur of
(1) the 18-month anniversary of the Effective Date of Termination and (2) the
end of the Term, all life, medical and dental insurance coverage as is
maintained by the Company or the Bank for full-time employees (or, in lieu of
providing any such coverage, the Company or the Bank may pay the Officer the
cash equivalent of the cost of such coverage), provided that the Officer shall
continue to pay all amounts in respect of such coverage that other employees
receiving the same level of coverage are required to pay. If the Effective Date
of Termination by the Company of the Officer's employment occurs at any time
following a Change in Control, the provisions of Section 12 shall apply in lieu
of the provisions of the immediately preceding sentence of this Section 9(a).
The lump sum payment referred to in section 9(a)(i)(A) shall be made to
                                        6
<PAGE>   7

the Officer as soon as practicable after the Effective Date of Termination, but
in no event later than 90 days thereafter.

     (ii) If the Merger Agreement is terminated and the Merger (as defined
therein) abandoned, then this Agreement shall be void ab initio, neither party
shall have any further rights or obligations hereunder, and, all prior
agreements between the Officer and the Company and/or the Bank shall remain and
continue in full force and effect in accordance with their terms, as if this
Agreement had not been adopted.

     (b) The Officer shall have no right to receive compensation or other
benefits under this Agreement for any period after the Effective Date of
Termination if the Officer's employment is terminated for "cause." As used in
this Agreement, "termination for cause" shall mean a termination for "cause" by
either the Company or the Bank and "cause" shall mean (i) willful and continued
failure by the Officer to materially perform his duties under this Agreement
after at least one warning in writing from the Company's Board of Directors
identifying specifically any such material failure and offering a reasonable
opportunity to cure such failure (provided, that failure to achieve performance
goals shall in no event be grounds for termination for "cause" hereunder); (ii)
the willful engaging by the Officer in material misconduct which causes material
injury to the Company or the Bank as specified in a written notice to the
Officer from the Board of Directors of the Company; (iii) material breach of
fiduciary duty involving personal profit; or (iv) conviction of a crime (other
than a traffic violation), habitual drunkenness, drug abuse, or excessive
absenteeism other than for illness, after a warning (with respect to drunkenness
or absenteeism only) in writing from the Board of Directors of the Company to
refrain from such behavior. No act or failure to act on the part of the Officer
shall be considered willful unless done, or omitted to be done, by the Officer
not in good faith and without reasonable belief that the action or omission was
in the best interest of the Company. Any termination of the Officer for "cause"
shall be based upon a finding of a Special Majority of the Board of Directors,
with notice thereof given to the Officer in accordance with Section 9(d).

     (c) Notwithstanding any other provision of this Section 9 or of Section 12,
if at the Effective Date of Termination any statute, regulation, order,
agreement, or regulatory interpretation thereof that is valid and binding upon
the Company or the Bank (excluding Sections 280G and 4999 of the Code and
regulations promulgated thereunder) (a "Regulatory Restriction") shall restrict,
prohibit or limit the amount of any payment or the provision of any benefit that
the Company or the Bank would otherwise be liable for under this Section 9 or
under Section 12, then the amount that the Company or the Bank shall pay to the
Officer hereunder shall not exceed the maximum amount permissible under such
Regulatory Restriction; provided that, if such Regulatory Restriction shall
subsequently be rescinded, superseded, amended or otherwise determined not to
restrict, limit or prohibit payment by the Company or the Bank of amounts
otherwise due the Officer hereunder, then the Company or the Bank shall promptly
thereafter pay to such Officer any amounts (or the value of any benefit)
previously withheld from such Officer as a result of such Regulatory
Restriction, and provided further that, if any Regulatory Restriction restricts,
prohibits or limits one of the Company or the Bank to a lesser extent than it
restricts, prohibits or limits the other of the two, then the entity least
restricted shall be obligated hereunder to perform any of the obligations of the
other hereunder to the fullest extent permitted by the Regulatory Restriction.

     (d) If subsequent to the Effective Time, the Officer's employment is
proposed to be terminated by the Company (whether or not for "cause" (as defined
in Section 9(b)), the Company shall deliver to the Officer a Notice of
Termination (as defined in Section 14) accompanied by a copy of a resolution
duly adopted by the affirmative vote of not less than a Special Majority of the
entire Board of Directors of the Company at a meeting called and held for that
purpose (after reasonable notice to the Officer and an opportunity for him,
together with counsel, to be heard before the Board of Directors), and if such
termination is for cause it shall include a finding that in the good faith
opinion of a Special Majority of the Board of Directors the Officer's conduct
constituted cause for termination and specifying the particulars thereof in
reasonable detail.

                                        7
<PAGE>   8

     10.  Voluntary Termination by the Officer.  (a) The Officer shall have the
right to terminate the Officer's employment under this Agreement at any time
following the Effective Time, whether for Material Change or any other reason,
upon at least 60 but not more than 90 days' prior written notice to the Company
(an "Officer's Termination Notice"). If this Agreement is terminated pursuant to
the immediately preceding sentence, then except as otherwise provided in
Sections 2(b), 7, 10(b) and 12 hereof, all of the Company's obligations under
this Agreement shall terminate, except that the Officer shall remain entitled to
any compensation or benefits earned prior to the Effective Date of Termination.

     (b) If the Officer shall terminate his employment pursuant to Section 10(a)
at any time when a Material Change (determined without regard to whether a
Change in Control has occurred) has occurred, then in addition to the benefits
provided in Section 10(a), the Officer shall also be entitled to the benefits
provided in Sections 7 and 9(a)(i) hereof; provided that, if such termination
occurs after a Change in Control has occurred, then the Officer shall be
entitled to the benefits of Section 12 in lieu of the provisions of Section
9(a)(i). For purposes of this Section 10, the term "Material Change" shall have
the same meaning as set forth in Section 12(c)(ii) hereof, except that in
determining whether a Material Change has occurred, (i) the fact that no Change
in Control shall have occurred shall be disregarded, (ii) the failure to provide
compensation or benefits required to be provided under this Agreement shall be
treated as a material breach of this Agreement, and (iii) whether there has been
a Material Change in the Officer's functions, duties or responsibilities, as
provided in clause (C) of such Section, shall be made by reference to the
functions, duties and responsibilities required to be provided under Section 4
hereof.

     11.  Additional Termination and Suspension Provisions.  There are hereby
included by reference any provisions that are required by applicable law or
regulation binding on the Company or the Bank to be included in an employment
agreement entered into by the Company or the Bank. If any such provision is a
Regulatory Restriction that restricts, prohibits or limits one of the Company or
the Bank to a lesser extent than it restricts, prohibits or limits the other of
the two, then the entity least restricted shall be obligated hereunder to
perform any of the obligations of the other hereunder to the fullest extent
permitted by the Regulatory Restriction.

     12.  Change in Control.  The provisions of this Section 12 shall only be
applicable during the Post-Merger Period; provided, that neither the Holding
Company Combination nor the Bank Combination (nor any other event or transaction
contemplated by or reasonably necessary to effectuate the purposes of the Merger
Agreement or between or among the Company, the Holding Company and their
respective Affiliates) shall be deemed to constitute a Change in Control for any
purpose of this Agreement. (a) As used in this Agreement, a "Change in Control"
shall be deemed to have occurred if the event set forth in any one of the
following paragraphs shall have occurred:

          (I) any Person is or becomes the Beneficial Owner, directly or
     indirectly, of securities of the Company (not including in the securities
     beneficially owned by such Person any securities acquired directly from the
     Company or its Affiliates) representing 35% or more of the combined voting
     power of the Company's then outstanding securities; or

          (II) the following individuals cease for any reason to constitute a
     majority of the number of directors then serving as directors of the
     Company: individuals who, immediately following the Effective Time,
     constitute the Board of Directors of the Company and any new director
     (other than a director whose initial assumption of office is in connection
     with the settlement of an actual or threatened election contest, including
     but not limited to a consent solicitation, relating to the election of
     directors of the Company) whose appointment or election by the Board of
     Directors of the Company or nomination for election by the Company's
     stockholders was approved or recommended by a vote of at least two-thirds
     ( 2/3) of the directors then still in office who either were directors
     immediately following the Effective Time or whose appointment, election or
     nomination for election was previously so approved or recommended; or

          (III) there is consummated a merger or consolidation of the Company or
     any direct or indirect subsidiary of the Company with any other corporation
     or entity, other than (i) a merger or consolidation which would result in
     the voting securities of the Company outstanding immediately
                                        8
<PAGE>   9

     prior to such merger or consolidation continuing to represent (either by
     remaining outstanding or by being converted into voting securities of the
     surviving entity or any Parent thereof), in combination with the ownership
     of any trustee or other fiduciary holding securities under an employee
     benefit plan of the Company or any subsidiary of the Company, at least 65%
     of the combined voting power of the securities of the Company, such
     surviving entity or any Parent thereof outstanding immediately after such
     merger or consolidation or (ii) a merger or consolidation effected solely
     to implement a recapitalization of the Company or the Bank (or similar
     transaction) in which no Person is or becomes the Beneficial Owner,
     directly or indirectly, of securities of the Company or the Bank (not
     including in the securities beneficially owned by such Person any
     securities acquired directly from the Company or its Affiliates)
     representing 35% or more of the combined voting power of the Company's or
     the Bank's then outstanding securities; or

          (IV) the stockholders of the Company or the Bank approve a plan of
     complete liquidation or dissolution of the Company or the Bank,
     respectively, or there is consummated a sale or disposition by the Company
     or any of its subsidiaries of any assets which individually or as part of a
     series of related transactions constitute all or substantially all of the
     Company's consolidated assets (provided that, for these purposes, a sale of
     all or substantially all of the voting securities of the Bank or a Parent
     of the Bank shall be deemed to constitute a sale of substantially all of
     the Company's consolidated assets), other than any such sale or disposition
     to an entity at least 65% of the combined voting power of the voting
     securities of which are owned by stockholders of the Company in
     substantially the same proportions as their ownership of the voting
     securities of the Company immediately prior to such sale or disposition; or

          (V) the execution of a binding agreement that if consummated would
     result in a Change in Control of a type specified in clause (I) or (III) of
     this Section 12(a) (an "Acquisition Agreement") or of a binding agreement
     for the sale or disposition of assets that, if consummated, would result in
     a Change in Control of a type specified in clause (IV) of this Section
     12(a) (an "Asset Sale Agreement") or the adoption by the Board of Directors
     of the Company or the Bank of a plan of complete liquidation or dissolution
     of the Company or the Bank that, if consummated, would result in a Change
     in Control of a type specified in clause (IV) of this Section 12(a) (a
     "Plan of Liquidation"), provided however, that a Change in Control of the
     type specified in this clause (V) shall not be deemed to exist or have
     occurred as a result of the execution of such Acquisition Agreement or
     Asset Sale Agreement, or the adoption of such a Plan of Liquidation, from
     and after the Abandonment Date if the Effective Date of Termination of the
     Officer's employment has not occurred on or prior to the Abandonment Date.
     As used in this Section, the term "Abandonment Date" shall mean the date on
     which (A) an Acquisition Agreement, Asset Sale Agreement or Plan of
     Liquidation is terminated (pursuant to its terms or otherwise) without

     Asset Sale Agreement abandon the transactions contemplated thereby, (C) the
     Bank or the Company abandons a Plan of Liquidation or (D) a court or
     regulatory body having competent jurisdiction enjoins or issues a cease and
     desist or stop order with respect to or otherwise prevents the consummation
     of, or a regulatory body notifies the Bank or the Company that it will not
     approve, an Acquisition Agreement, Asset Sale Agreement or Plan of
     Liquidation or the transactions contemplated thereby and such injunction,
     order or notice has become final and not subject to appeal.

     As used in connection with the foregoing definition of Change in Control,
"Affiliate" shall have the meaning set forth in Rule 12b-2 promulgated under
Section 12 of the Exchange Act; "Beneficial Owner" shall have the meaning set
forth in Rule 13d-3 under the Exchange Act; "Exchange Act" shall mean the
Securities Exchange Act of 1934, as amended from time to time; "Parent" shall
mean any entity that becomes the Beneficial Owner of at least 80% of the voting
power of the outstanding voting securities of the Company or of an entity that
survives any merger or consolidation of the Company or any direct or indirect

3(a)(9) of the Exchange Act, as modified and used in Sections 13(d) and 14(d)

subsidiaries, (ii) a trustee or other fiduciary holding securities under

                                        9
<PAGE>   10

an employee benefit plan of the Company or any of its Affiliates, (iii) an
underwriter temporarily holding securities pursuant to an offering of such
securities, or (iv) a corporation or entity owned, directly or indirectly, by
the stockholders of the Company in substantially the same proportions as their
ownership of stock of the Company.

     (b) If the Company shall relocate its principal executive offices after a
Change in Control, and if the Officer is required, as a result, to change the
Officer's principal residence, the Company shall (i) promptly pay (or reimburse
the Officer for) all reasonable moving expenses incurred by the Officer as a
result of such change in the Officer's principal residence, and (ii) indemnify
the Officer against, and reimburse the Officer for, any loss incurred as the
result of the sale of the Officer's principal residence (which loss shall be
computed for the purpose of this Agreement as the difference between the actual
sales price (net of closing costs and brokerage fees) of such residence and the
fair market value of such residence (computed as of the time the Company
relocates its principal executive offices) as determined by an independent real
estate appraiser designated and paid by the Company and acceptable to the
Officer), provided that such sale of the Officer's principal residence occurs
within six months after the Company relocates its principal executive offices.

     (c)(i) If a Change in Control shall occur, the Officer shall be entitled to
the compensation and benefits provided in paragraphs (d), (e), (f) and (g) of
this Section 12 upon the subsequent termination by the Company of the Officer's
employment at any time during the remaining Term in effect at the time of the
Change in Control, other than a termination for cause (as defined in Section
9(b)), provided that the rights to any such compensation and benefits shall be
subject to the limitations and provisions set forth in Section 9(c).

     (ii) If a Change in Control shall occur, and thereafter the Board of
Directors of the Company or the Bank or, if the Company or the Bank is not the
surviving entity in the transaction giving rise to such Change in Control, the
Board of Directors of the ultimate parent entity surviving such Change in
Control, either (A) fails to elect or re-elect or appoint or reappoint the
Officer to the offices or positions specified in Section 3 with the Company and
the Bank or, if the Company or the Bank is not the surviving ultimate parent
entity in the transaction giving rise to such Change in Control, with the
ultimate parent entity surviving such Change in Control, (B) materially breaches
this Agreement, (C) makes a material change in the Officer's functions, duties
or responsibilities, which change would cause the Officer's position with the
Company or the Bank or, if the Company or the Bank is not the surviving entity
in the transaction giving rise to such Change in Control, with the entity
surviving such Change in Control to become one of lesser responsibility,
importance or scope from that in effect immediately prior to the time of the
Change in Control, (D) requires that the Officer's services be rendered
primarily at a location or locations outside of the New York metropolitan area
or (E) during the Initial Post-Merger Period, adopts a resolution approved by at
least a simple majority of the Board of Directors providing that the Officer
shall not become Chairman of the Board and Chief Executive Officer of the
Company and the Bank (an event specified in clause (A), (B), (C), (D) or (E) is
hereafter referred to as a "Material Change"), the Officer shall be entitled to
the compensation and benefits provided in paragraphs (d), (e), (f) and (g) of
this Section 12 (subject to the limitations and provisions set forth in Section
9(c)) upon the subsequent termination of the Officer's employment, at any time
during the remaining Term in effect at the time of the Change in Control, by the
Officer. Any good faith determination by the Officer that a Material Change has
taken place shall be presumed to be correct and therefore shall be controlling
for all purposes of this Agreement, unless, within 30 days after receipt of the
Officer's Termination Notice a Special Majority of the Board of Directors of the
Company shall determine that no such Material Change has occurred, in which
event no such presumption shall be made, and the determination of whether a
Material Change has occurred shall be resolved in accordance with Section 22
hereof.

     (iii) If the Officer's employment is terminated by the Officer during the
remaining Term in effect at the time of the Change in Control and no Material
Change shall have occurred, then the provisions of Section 10 shall apply in
lieu of the provisions of paragraphs (d), (e) and (f) of this Section 12.

                                       10
<PAGE>   11

     (iv) Only for purposes of determining whether there has been a termination
of the Officer's employment during the remaining Term in effect at the time of a
Change in Control (as specified in paragraphs (c)(i) or (c)(ii) of this Section
12) so as to entitle the Officer to the compensation and benefits provided in
paragraphs (d), (e), (f) and (g) of this Section 12, a termination of the
Officer's employment following a Change in Control shall be deemed to have
occurred on such date during the remaining Term that (A) Notice of Termination
(as defined in Section 14(b)) is given by the Company to the Officer (regardless
of the Effective Date of Termination specified therein), or (B) an Officer's
Termination Notice (as defined in Section 10) is given by the Officer to the
Company (regardless of the Effective Date of Termination specified therein).
Notwithstanding the immediately preceding sentence, the Officer shall continue
to be employed by the Company and the Bank pursuant to this Agreement until the
Effective Date of Termination specified in the Notice of Termination or
Officer's Termination Notice, as the case may be.

     (d)(i) Upon the occurrence of a Change in Control followed by any
termination of the Officer's employment pursuant to Section 12(c)(i) or (c)(ii),
the Bank shall pay to the Officer, as a severance payment for services
previously rendered to the Bank, a lump sum equal to three times the Officer's
Deemed Annual Compensation, as in effect immediately prior to the Effective Date
of Termination (without regard to any decrease in the Officer's Deemed Annual
Compensation made after the Change in Control). As used in this Section
12(d)(i), the term "Deemed Annual Compensation" shall mean, at any time, an
amount equal to the sum of (A) the Officer's annual salary (as defined in
Section 5(a)) at such time, plus (B) the higher of (y) the amount of the target
bonus which the Officer is eligible to earn for the year which includes the day
immediately prior to the Change in Control, or (z) the amount of the average
bonus or other cash incentive earned by the Officer with respect to the two most
recently completed fiscal years.

     (ii) Upon the occurrence of a Change in Control followed by any termination
of the Officer's employment pursuant to Section 12(c)(i) or (c)(ii), to the
extent not otherwise limited pursuant to Section 9(c), (x) each option granted
after the date hereof under a stock incentive or stock option plan of the
Company and held by the Officer shall (to the extent permitted by the plan under
which such option was granted), notwithstanding anything to the contrary in the
grant letter related to such option and regardless of the actual Effective Date
of Termination, immediately vest and remain exercisable for the term specified
in such grant letter as if there had been no termination of the Officer's
employment and the Officer remained in the employment of the Company for the
entire term of such option and (y) each share of Restricted Stock granted
pursuant to Section 5(h) shall (to the extent permitted by the plan under which
such Restricted Stock was granted), notwithstanding anything to the contrary in
the grant letter related to such Restricted Stock and regardless of the actual
Effective Date of Termination, vest and the restrictions thereon shall lapse at
such time as they would have otherwise vested, and the restrictions thereon
would have otherwise lapsed, as if there had been no termination of the
Officer's employment and the Officer remained in the employment of the Company
through the period required for the vesting of and lapsing of the restrictions
on such stock.

     (e) Any payment pursuant to Section 12(d)(i) shall be made to the Officer
within 30 days after the Effective Date of Termination.

     (f) Upon the occurrence of a Change in Control followed by any termination
of the Officer's employment pursuant to Section 12(c)(i) or (c)(ii), to the
extent not otherwise limited pursuant to Section 9(c), the Company or the Bank
shall, for the remainder of the Officer's life, and for the remainder of the
life of the Officer's spouse (to whom the Officer was married as of the
Effective Date of Termination), continue to provide to the Officer and such
spouse the same level of disability, medical and dental insurance coverage as is
maintained from time to time by the Company or the Bank for full-time employees
and their spouses, provided that (x) the Officer (and, after the Officer's
death, the Officer's surviving spouse) shall continue to pay all amounts in
respect of such coverage that the other employees, retirees, or surviving
spouses, as applicable, receiving the same levels of coverage are required to
pay, (y) any medical coverage may be modified so that Medicare (or other
governmental coverage) is primary, with coverage provided by the Company or the
Bank supplementary, to the extent permitted by law, and
                                       11
<PAGE>   12

(z) in lieu of providing any benefit hereunder, the Company or the Bank may pay
the Officer (and after the Officer's death, the Officer's surviving spouse) the
cash equivalent of the cost of such coverage.

     (g)(i) If, on account of events described in Sections 12(c)(i) or 12(c)(ii)
following a Change in Control, any payment or other benefit paid or to be paid
or any property transferred or to be transferred with respect to one or more
calendar years by or on behalf of the Company (or any affiliate of the Company)
to the Officer pursuant to this Agreement or pursuant to the terms of any other
plan, arrangement or agreement of the Company (or any of its subsidiaries)
(collectively, a "Severance Payment") shall constitute an "excess parachute
payment" within the meaning of Section 280G(b) of the Code subject to the tax
imposed by Section 4999 of the Code (the "Excise Tax"), then the Company shall
pay to the Officer an additional amount (the "Gross Up Payment") such that the
amount paid or transferred to the Officer, after deduction of any Excise Tax on
the Severance Payment, and any federal, state and local income tax, employment
tax and Excise Tax upon the Gross Up Payment, shall be equal to the Severance
Payment. In addition, if, absent a Change in Control or in other circumstances
following a Change in Control, notwithstanding the reductions mandated by
Section 9(c), the benefits described in Section 7 and any other benefits payable
in connection with the Holding Company Combination (the "Section 7 Benefits")
shall constitute "excess parachute payments" within the meaning of Section
280G(b) of the Code subject to the Excise Tax, then the Company shall pay to the
Officer one or more Gross Up Payments such that the amount of such Gross Up
Payments, when combined with such Section 7 Benefits, after deduction of any
Excise Tax on the Section 7 Benefits, and any federal, state and local income
tax, employment tax and Excise Tax upon the Gross Up Payments, shall be equal to
such Section 7 Benefits.

     (ii) For purposes of determining under Section 12(g)(i) whether any portion
of a Severance Payment or Section 7 Benefit will be subject to the Excise Tax
and the amount of such Excise Tax, (A) the Severance Payment or Section 7
Benefit and payments provided for in Section 12(g)(i) shall be treated as
"parachute payments" within the meaning of Section 280G(b)(2) of the Code, and
all "excess parachute payments" within the meaning of Section 280(G)(b)(1) of
the Code shall be treated as subject to the Excise Tax, unless and to the extent
that tax counsel selected by the Company's independent auditors and acceptable
to the Officer is of the opinion that the Severance Payment or Section 7 Benefit
(in whole or in part) does not constitute a "parachute payment" or such "excess
parachute payment" (in whole or in part) represents reasonable compensation for
services actually rendered within the meaning of Section 280G(b)(4) of the Code
in excess of the allocable base amount within the meaning of Section 280G(b)(3)
of the Code, or the Severance Payment or Section 7 Benefit is otherwise not
subject to the Excise Tax, (B) the amount of the Severance Payment or Section 7
Benefit that is treated as subject to the Excise Tax shall be equal to the
lesser of (X) the total amount of the Severance Payment or Section 7 Benefit, as
applicable, and (Y) the amount of "excess parachute payments" within the meaning
of Section 280G(b)(1) of the Code (after applying clause (A) above), (C) any
Gross Up Payment pursuant to Section 12(g)(i) shall be treated as subject to the
Excise Tax in its entirety and (D) the value of any non-cash benefits or any
deferred payment or benefit shall be determined by the Company's independent
auditors in accordance with the principles of Sections 280G(d)(3) and (4) of the
Code.

     (iii) If in circumstances described in Section 12(g)(i), by reason of the
filing by the Officer of an amended tax return, an audit by the Internal Revenue
Service or other taxing authority, or a final determination by a court of
competent jurisdiction, it is determined that "excess parachute payments"
exceeding those previously reported in his tax returns were received by the
Officer and as a result an additional Excise Tax (the "Additional Excise Tax")
shall become due, the Company shall pay the Officer an additional amount (the
"Subsequent Gross Up Payment") such that the amount paid or transferred to the
Officer, after deduction of (A) any Additional Excise Tax and (B) on an after
tax basis, any interest, additions and penalties with respect to the Additional
Excise Tax and (C) any federal, state and local income tax, employment tax and
Excise Tax upon the Subsequent Gross Up Payment and (D) the payments provided
for in Section 12(g)(i), shall be equal to the Severance Payment or Section 7
Benefits, as appropriate.

                                       12
<PAGE>   13

     (iv) Any Gross Up Payment required hereunder shall be made at least ten
days prior to the due date (without regard to extensions) of the Officers's
federal income tax return for the year with respect to which the "excess
parachute payment" is deemed made under the Code. Any Subsequent Gross Up
Payment required hereunder shall be made to the Officer within 30 days after the
amount thereof is determined. Notwithstanding the two immediately preceding
sentences, the Company shall pay any federal, state and local tax or taxes and
employment taxes required to be withheld from the Officer's wages (within the
meaning of Section 3121 and 3402 of the Code) with respect to the "excess
parachute payment" and any such tax or taxes paid by the Company to the Internal
Revenue Service or state or local taxing authority shall constitute payment to
the Officer.

     (v) If the Excise Tax is finally determined (whether by the filing of an
amended tax return by the Officer, by audit of the Internal Revenue Service or
other taxing authority, or by a final determination of a court of competent
jurisdiction) to be less than the amount paid to or on behalf of the Officer
under the provisions of Sections 12(g)(i)-(iv) and the overpayment is refunded
to the Officer, the Officer shall repay to the Company, promptly following the
receipt of the refund, the portion of the Gross Up Payment (and/or Subsequent
Gross Up Payment) attributable to such reduction of the Excise Tax (plus the
portion attributable to federal, state and local income tax and employment taxes
imposed on the portion being repaid by the Officer but only to the extent that
the repayment may result in a tax benefit to the Officer under Section 1341 of
the Code and similar provisions of applicable state and local law).

     (vi) The provisions of this Section 12(g) shall inure to the benefit of the
Officer during the Term of this Agreement regardless of whether or not his
employment is terminated, and if the Officer's employment is terminated, the
rights and obligations of the Officer and the Company under this Section 12(g)
shall survive the termination of this Agreement.

     13.  Post-Termination Obligations of the Officer.  (a) In addition to any
related requirements that may apply pursuant to the terms of the Consulting
Agreement, upon any termination of the Officer's employment during the Term of
this Agreement or upon termination of the Officer's employment after the
expiration of the Term of this Agreement or upon retirement, the Officer agrees
(i) not to make any disclosure in violation of Section 13(b), (ii) to return to
the Company and the Bank all material documents relating to the business of the
Company and the Bank that are in the Officer's possession or under the Officer's
control, and (iii) except if the termination or retirement occurs after a Change
in Control, not to solicit (directly or indirectly), for one year following the
Effective Date of Termination (or date of termination after the expiration of
the Term) or retirement, the employment of any person who is an employee of the
Company or the Bank on the Effective Date of Termination (or date of termination
after the expiration of the Term) or retirement or who, within six months prior
to the Effective Date of Termination (or date of termination after the
expiration of the Term) or retirement, was an employee of the Company, unless
the Officer receives written permission from the Company to engage in the
activities proscribed by this Section 13(a) or by Section 13(b) or to be
relieved of any obligation under Section 13(a)(ii).

     (b) The Officer recognizes and acknowledges that the confidential business
activities and plans for business activities of the Company and its Affiliates,
as they may exist from time to time, are valuable, special and unique assets of
the Company. The Officer shall not, during or at any time after the Officer's
employment, disclose any knowledge of the past, present or planned business
activities of the Company or its Affiliates that are of a confidential nature
(collectively, the "Company's Confidential Activities") to any person, firm,
corporation, company, thrift institution or other entity for any reason or
purposes whatsoever. Notwithstanding anything in this Section 13(b) to the
contrary, the Officer (i) may disclose any knowledge of banking, financial
and/or economic principles, concepts or ideas that are not derived from the
Company's Confidential Activities, and (ii) shall not be precluded from
disclosures respecting the Company's Confidential Activities that are (A) made
pursuant to compulsory legal process or when required by an appropriate
governmental agency; (B) public knowledge or become public without the Officer's
breach of this Section 13(b); (C) already known to the party to whom the Officer
makes such disclosures; or (D) approved by the Company for disclosure.

                                       13
<PAGE>   14

     (c) The parties, recognizing that irreparable injury will result to the
Company, its business and property in the event of the Officer's breach or
threatened breach of Section 13(a) or (b), agree that in the event of such
breach or threatened breach by the Officer, the Company will be entitled, in
addition to any other remedies and damages that may be available, to seek and
obtain an injunction to restrain the violation of Section 13(a) or (b) by the
Officer.

     14.  Notices.  (a) All notices under this Agreement shall be in writing and
shall be delivered personally, sent by registered or certified mail, return
receipt requested or sent by recognized next-day courier service, (a) to the
Company, at Hudson United Bancorp, 1000 MacArthur Boulevard, Mahwah, New Jersey
07430 (attention: General Counsel), (b) to the Bank at Hudson United Bank, 1000
MacArthur Boulevard, Mahwah, New Jersey 07430 (attention: General Counsel) and
(C) to the Officer, at his address as it appears on the books and records of the
Company or to such other address as either party may hereafter designate in
writing in the manner provided in this Section 14. All notices under this
Agreement shall be deemed given (i) upon receipt if delivered personally, (ii)
on the third business day after deposit in a facility of the U.S. Postal Service
with postage prepaid, if delivered by registered or certified mail, or (iii) on
the first business day following the date of dispatch if delivered by a
recognized next-day courier service.

     (b) Any purported termination of the Officer's employment with the Company
and the Bank pursuant to Sections 6 or 9 shall be communicated to the Officer by
means of a written notice (a "Notice of Termination"). The Notice of Termination
shall (i) indicate a specific termination provision relied upon, (ii) set forth
in reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Officer's employment under the provision so indicated, and
(iii) specify the Effective Date of Termination; provided, however, that no such
Notice of Termination shall specify an Effective Date of Termination that is
prior to the date on which any such Notice of Termination is given.

     (c) As used in this Agreement, the term "Effective Date of Termination"
shall mean (i) the date on which the Officer's employment with the Company and
the Bank is to terminate, as specified in a Notice of Termination given by the
Company or the Bank, or (ii) the date on which the Officer's employment with the
Company and the Bank is to terminate, as specified in an Officer's Termination
Notice given by the Officer.

     15.  No Duty to Mitigate.  Except as otherwise expressly provided herein,
if the Officer shall continue to receive compensation or benefits or severance
pay pursuant to this Agreement after its termination, (a) the Officer shall have
no duty to mitigate such payments by seeking or obtaining other employment or
otherwise, and (b) in the event the Officer does obtain other employment, such
payments from the Company shall not be reduced by compensation received from
such other employment.

     16.  Complete Understanding.  This Agreement constitutes the complete
understanding between the parties with respect to its subject matter and merges
and supersedes all prior oral and written agreements and understandings and all
contemporaneous oral agreements and understandings, including, without
limitation, that certain agreement (the "Prior Agreement") dated January 1, 1997
between the Officer and the Company (and the Officer by entering into this
Agreement specifically disclaims any right to receive any payments or any other
benefits under that agreement) and any other employment agreement heretofore
executed by the Officer and the Company or any of its predecessors or
Affiliates. Notwithstanding the foregoing, if any Regulatory Restriction shall
prevent this Agreement from going into effect, shall void this Agreement in its
entirety, or shall prohibit the Company and the Bank from carrying out all of
the provisions of Sections 7, 9, 10 or 12 hereof, then the Officer shall be
entitled to the benefits of Sections 9 and 10 of the Prior Agreement to the
extent that such benefits exceed the benefits, after application of any
Regulatory Restriction, available under this Agreement. This Agreement may not
be amended, terminated or rescinded except in a writing signed by all the
parties hereto; provided, that no amendment or other modification to this
Agreement made prior to the Effective Time shall be valid or binding unless
agreed to by all parties hereto and also consented to by Bancorp; and provided
further that any amendment or modification to this Agreement agreed to on behalf
of the Company shall be approved by a Special Majority of the Board of
Directors. Notwithstanding the foregoing or any other provision in

                                       14
<PAGE>   15

this Agreement to the contrary, any provision in this Agreement requiring or
permitting any action, determination or decision to be taken or made by a
Special Majority of the Board of Directors shall terminate on December 31, 2002,
after which any such action, determination or decision may be taken or made by a
simple majority of the Board of Directors.

     17.  No Waiver.  The failure of any party at any time to require
performance by any other party of a provision of this Agreement or to resort to
a remedy at law or in equity or otherwise shall in no way affect the right of
such party to require full performance or to resort to such remedy at any time
thereafter nor shall a waiver by any party of the breach of any provision of
this Agreement be taken or held to be a waiver of any subsequent breach of such
provision unless expressly so stated in writing. No waiver of any of the
provisions of this Agreement shall be effective unless in writing and signed by
the party to be charged.

     18.  Governing Law.  This Agreement shall be governed by the laws of the
State of New York, without regard to conflict of laws principles applied in the
State of New York.

     19.  Headings.  The headings to the Sections of this Agreement are for
convenience of reference only and shall not be given any effect in the
construction or interpretation of this Agreement.

     20.  Severability.  If any provision of this Agreement is held by a court
or other authority having competent jurisdiction to be invalid, void or
otherwise unenforceable, in whole or in part, by reason of any applicable law,
statute or regulation or any interpretation thereof, then (a) the remainder of
the provisions of this Agreement shall remain in full force and effect and in no
way affected, impaired or invalidated and (b) the provision so held to be
invalid, void or otherwise unenforceable shall be deemed modified in amount,
duration, scope or otherwise to the minimum extent necessary so that such
provision shall not be invalid, void or otherwise unenforceable by reason of
such law, statute, regulation or interpretation and such provision, as so
modified, shall remain in full force and effect.

     21.  Payment of Legal Fees.  If any legal action or proceeding is commenced
to enforce or interpret the provisions of this Agreement, or any plan, agreement
or arrangement referenced in this Agreement, or to recover damages for breach
thereof, including without limitation any proceeding commenced under Section 22
hereof, all reasonable legal fees, disbursements and court or arbitration costs
paid or incurred by the Officer arising out of or resulting from such action or
proceeding shall be paid or reimbursed to the Officer by the Company, provided
that the action or proceeding is not dismissed or summarily decided against the
Officer.

     22.  Dispute Resolution.  Any dispute or controversy arising under, in
connection with or relating to this Agreement or the transactions contemplated
hereby shall be subject to compulsory mediation in New York City in accordance
with the National Rules for the Resolution of Employment Disputes of the
American Arbitration Association then in effect. In the event that such
compulsory mediation does not result in a resolution of such dispute or
controversy which is acceptable to both the Company and the Officer, such
dispute or controversy shall be resolved exclusively by arbitration in New York
City in accordance with the National Rules for the Resolution of Employment
Disputes of the American Arbitration Association then in effect. The parties
hereto agree that the decision of such arbitration shall be final and binding
upon the parties and upon confirmation of the decision resulting from such
arbitration, judgment may be entered on the arbitrators' award in any court
having jurisdiction.

     23.  Taxes.  Any payments due to the Officer pursuant to this Agreement
shall be reduced by all applicable federal, state, city or other taxes required
by law to be withheld with respect to such payments.

                                       15
<PAGE>   16

     24.  Limitation on Payments.  Any payments made to the Officer pursuant to
this Agreement, or otherwise, are subject to and conditioned upon their
compliance with, or the non-applicability thereto of, 12 USC sec. 1828(k) and
any regulations promulgated thereunder.

                      Re: Joint Proxy Statement-Prospectus

Ladies and Gentlemen:

     Reference is hereby made to our opinion letter (our "Opinion Letter") dated
February 8, 2000 with respect to the fairness from a financial point of view to
holders of common stock, no par value ("Hudson Common Stock"), of Hudson United
Bancorp ("Hudson") of the Exchange Ratio (as defined below) contemplated by the
Agreement and Plan of Merger (the "Agreement"), dated as of September 15, 1999,
as amended and restated as of December 27, 1999, between Hudson and Dime
Bancorp, Inc. ("Dime"). The Agreement provides for the merger of Hudson with and
into Dime under the name "Dime United Bancorp, Inc." (the "Merger"), pursuant to
which, among other things, each share of Hudson Common Stock will be exchanged
for one share (the "Exchange Ratio") of common stock, par value $0.01 per share,
of Dime ("Dime United Common Stock"), and each share of common stock, par value
$0.01 per share, of Dime will be converted into 0.60255 shares of Dime United
Common Stock.

     Our Opinion Letter is provided to the Board of Directors of Hudson in
connection with the filing of the Registration Statement on Form S-4 of Dime
dated February 8, 2000, including the joint proxy statement-prospectus relating
to the special meetings of Dime and Hudson being held to vote on the merger (the
"Merger Proxy"), and is not to be used, circulated, quoted or otherwise referred
to for any other purpose, nor is it to be filed with, included in or referred to
in whole or in part in any registration statement, proxy statement or any other
document, except in accordance with our prior written consent.

     In that regard we hereby consent to the reference to our Opinion Letter in
the Merger Proxy under the captions "SUMMARY -- Hudson's Financial Advisor Says
the Hudson Exchange Ratio is Fair from a Financial Point of View to Hudson
Stockholders," "THE MERGER -- Background of the Merger," "THE MERGER -- Hudson's
Reasons for the Merger; Recommendation of Hudson's Board of Directors" and "THE
MERGER -- Opinion of Hudson's Financial Advisor" and to the inclusion of our
Opinion Letter in the Merger Proxy. We also consent to the filing with the
Securities and Exchange Commission of this consent letter as supplemental
information and not as "filed" material under the Securities Exchange Act of
1934. In giving such consent, we do not hereby admit that we come within the
category of persons whose consent is required under Section 7 of the Securities
Act of 1933 or the rules and regulations of the Securities and Exchange
Commission thereunder.

                                          Very truly yours,
