                            QUESTIONS AND ANSWERS ABOUT THE MERGER


Q.      Why are we receiving these documents?
A.      The Boards of Directors of Sterling Financial Corporation and Hanover
        Bancorp, Inc. provide this proxy statement/prospectus, their Annual
        Reports to Shareholders and their Annual Reports on Form 10-K to you to
        solicit your vote on proxies at the annual meetings of shareholders to
        be held at Willow Valley Family Resort and Conference Center, 2416
        Willow Street Pike, Lancaster, Pennsylvania at 9:00 a.m., local time, on
        Monday, May 22, 2000, for shareholders of Sterling and at Hanover
        Country Club, Lincolnway East, R.D. 1, Abbottstown, Pennsylvania, at
        9:30 a.m., on Tuesday, May 23, 2000, for shareholders of Hanover.

Q.      Who are the parties to the merger?
A.      Sterling and Hanover.

Q.      How will the merger be effected?
A.      Hanover will merge with and into Sterling. Sterling will survive the
        merger. Shareholders of Hanover will receive shares of common stock of
        Sterling in exchange for their shares in Hanover. Bank of Hanover and
        Trust Company, Hanover's wholly owned Pennsylvania chartered bank
        subsidiary and HOVB Investment Co., also a wholly owned subsidiary of
        Hanover, will continue operations as wholly owned subsidiaries of
        Sterling after the merger.

Q.      What do I need to do now?
A.      Just indicate on your proxy card how you want to vote your shares, then
        sign and mail your proxy card in the enclosed prepaid return envelope as
        soon as possible, so that your shares may be represented and voted at
        the Sterling annual meeting or the Hanover annual meeting.

        Your vote is very important. Approval of the merger agreement by
        Sterling shareholders requires the affirmative vote of 66 2/3 % of the
        outstanding shares entitled to vote at the Sterling annual meeting,
        present in person or by proxy. Hanover shareholder approval requires the
        affirmative vote of at least a majority of the outstanding shares of
        voting stock, present in person or by proxy, at the Hanover annual
        meeting. You should return your signed proxy card as soon as possible.

        Both the Sterling and Hanover Boards of Directors unanimously recommend
        voting "FOR" the agreement.

                                            Q&A-1
<PAGE>   8
Q.      If my shares are held in "street name" by my broker, will my broker vote
        my shares for me?
A.      Your broker will vote your shares with respect to the merger only if you
        provide instructions on how to vote. You should follow the directions
        provided by your broker. Without instructions, your shares will not be
        voted on the merger agreement.

Q.      Can I change my vote after I have mailed my signed proxy card?
A.      Yes. There are three ways for you to revoke your proxy and change your
        vote.

        -       You may send a written notice to the person to whom you
                submitted your proxy stating that you would like to revoke your
                proxy.
        -       You may complete and submit a new proxy card with a later date.
        -       You may vote in person at the annual meeting.
        If you have instructed a broker to vote your shares you must follow
        directions received from your broker to change your vote.


Q.      Who will be sending in their stock certificates?
A.      Only Hanover shareholders will be required to send in their stock
        certificates after approval of the merger.

Q.      Should I send in my stock certificates now?
A.      No. Shortly after the merger is completed, Sterling's transfer agent,
        American Stock Transfer & Trust Company, will send you written
        instructions for exchanging your Hanover stock certificates. They will
        request that you return your Hanover stock certificates at that time.

Q.      When do you expect to merge?
A.      We are working towards completing the merger as quickly as possible. In
        addition to the approval of Sterling and Hanover shareholders, we must
        also obtain regulatory approvals. We expect to receive all necessary
        approvals and complete the merger by June 30, 2000.

                                     SUMMARY

        This summary highlights selected information from this proxy statement.
It may not contain all of the information that is important to you. You should
read carefully this entire proxy statement and the attached annexes. See "Where
You Can Find More Information" on page __ for reference to additional
information available to you regarding Sterling Financial Corporation and
Hanover Bancorp, Inc.

THE MERGER

        If the merger is completed, shareholders of Hanover will receive shares
of Sterling common stock, plus cash instead of any fractional share, in exchange
for their Hanover common stock. Sterling shareholders will continue to hold
their shares of Sterling common stock. Hanover shareholders will receive .93
shares of Sterling for each share of Hanover common stock.

        Because the market price of Sterling stock fluctuates, you will not know
when you vote exactly what the Sterling shares will be worth when issued in the
merger.

NO FEDERAL INCOME TAX ON SHARES RECEIVED IN MERGER

        Hanover shareholders generally will not recognize gain or loss for
federal income tax purposes upon receipt of shares of Sterling common stock
received in the merger. Sterling's attorneys have issued a legal opinion to this

may vary among shareholders. We urge you to contact your own tax advisor to
understand fully how the merger will affect you.

                           COMPARATIVE PER SHARE DATA

        We summarize below the per share information for Sterling and Hanover on
a historical, pro forma combined and equivalent basis. You should read this
information in conjunction with Sterling's and Hanover's historical financial
statements and the related notes contained in the annual and quarterly reports
and other documents filed with the Commission. See "AVAILABLE INFORMATION." The
Sterling proforma information gives effect to the merger, accounted for as a
pooling of interests, assuming that .93 shares of Sterling common stock are
issued for each outstanding share of Hanover's common stock. Hanover's
equivalent pro forma share amounts are calculated by multiplying the pro forma
Sterling basic and diluted earnings per share, Sterling pro forma per share
dividend and Sterling pro forma book value per common share by the exchange
ratio of .93 shares of Sterling common stock so that the per share amounts equal
the respective values for one share of Hanover common stock. Do not rely on the
pro forma information as being indicative of the historical results that we
would have had if we had been combined or of the future results that we will
experience after the merger. Pro forma information does not include any expense
savings anticipated as a result of the merger.

                  PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

         The following tables set forth selected unaudited pro forma financial
data reflecting the merger.

         We prepared the pro forma information assuming that shareholders of
Hanover will receive .93 shares of Sterling common stock in the merger for each
share of Hanover common stock they own. Sterling pro forma financial information
included in this proxy statement is presented for illustrative purposes only.
The pro forma financial information does not necessarily reflect the actual
results of Sterling following completion of the merger.

         We prepared the pro forma information using the "pooling-of-interests"
method of accounting for business combinations. Use of this method is a
pre-condition for the completion of the merger.

         The pro forma information presented does not give effect to any cost
savings that may be realized nor any merger-related expenses that may be
incurred as a result of the merger. It also ignores the effect of cash payments
that will be required for fractional shares and may be paid to dissenting
shareholders. The amount of these cash payments is impossible to estimate but we
believe it to be immaterial.

              FOR THE YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

         The following three tables show pro forma statements of income for the
years ended December 31, 1999, 1998 and 1997. We prepared this pro forma
information under the pooling-of-interests method of accounting assuming that
the merger occurred on the first day of each period for which we present
information. Under the pooling-of-interests method of accounting, the income
statements of the separate companies are added together for each period shown.
The unaudited pro forma condensed combined income statements do not include any
non-recurring material expenses related to the Hanover acquisition. Sterling is
currently in the process of estimating the dollar amount of such expenses. You
should read this pro forma information together with the historical financial
statements of Sterling and Hanover incorporated by reference in this proxy
statement. See "WHERE YOU CAN FIND MORE INFORMATION."

         The Board of Directors of Hanover has unanimously approved the
agreement and recommends a vote FOR approval and adoption of the agreement, FOR
approval of the Hanover adjournment proposal and FOR the election, as directors,
of the nominees of the Board of Directors.

<PAGE>   36
         -        Attending Hanover's shareholders meetings and any adjournment
                  of the meetings and voting shares over which the individual

                  -        Vote shares over which the individual has control in
                           favor of a transaction with a third party;

                  -        Transfer shares over which the individual has
                           control;

fiduciary duties as a director or officer of Hanover.

         As of both the Sterling record date and the Hanover record date,
neither Sterling nor Hanover had voting power with respect to any shares of

corporation's independent auditors.

         In the case of shares of Hanover, proxy holders will vote properly
executed proxies that do not contain voting instructions in favor of the
agreement, in favor of the Hanover adjournment proposal and in favor of the
election, as directors, of the nominees of the Board of Directors.

         Sterling and Hanover each intend to count shares of Sterling common
stock or Hanover common stock, as the case may be, present in person at the
meetings but not voting, and shares of Sterling common stock or Hanover common
stock, as the case may be, for which they have received proxies but with respect
to which holders of shares have abstained or not voted on any matter, as present
at the meetings for purpose of determining the presence of a quorum for the
transaction of business.

         A broker cannot vote your shares with respect to the merger without
specific instructions from you, the shareholder. Abstentions and broker
non-votes relating to shares of Sterling or Hanover common stock will not
constitute or be counted as votes "cast," but will be counted for the
determination of a quorum, for purposes of the Sterling annual meeting and for
the Hanover annual meeting. Neither Sterling nor Hanover expect any matter other
than those referred to in this proxy will be brought before either of the
meetings. If, however, other matters are properly presented for a vote, the
persons named as proxies will vote in accordance with their judgement with
respect to such to matters.

         If you sign your proxy but do not make any selections, you give
discretionary authority to the proxy holder to vote on the proposals at the
meeting. Also, every proxy gives the holder discretionary authority to vote on
other matters that may arise at the meeting of which management is not currently
aware. However, the proxy holders will not vote any proxy that withholds
authority or that is voted against the merger in favor of any adjournment of the
meeting.

         If you execute a proxy, you can revoke it at any time up to the time of
the vote on the issue. Unless revoked, shares represented by proxies will be
voted at the meetings and at all adjournments or postponements of the meetings.
Your attendance at the meeting will not revoke your proxy. Proxies may be
revoked by:

         Delivery of a notice of revocation or of a later-dated proxy to:

         If a quorum is not present at the beginning of the meeting, the Board
of Directors of Sterling or Hanover, as the case may be, intend to adjourn the
meeting to another place and time without further notice to the shareholders. If
for any other reason the Board of Directors of Sterling or Hanover believe
additional time should be allowed to obtain proxies, the Board may adjourn the
meeting with a vote of a majority of the shares outstanding. If the Board
proposes to adjourn the meeting, the proxy holders will vote all shares for
which they have voting authority in favor of the adjournment.

                                  MATTER NO. 1
                  APPROVAL OF THE AGREEMENT AND PLAN OF MERGER

         In this section we describe the material terms and provisions of the
proposed merger. A copy of the agreement that provides for the merger is
attached to this proxy statement/prospectus as Annex A. This is only a
discussion of material terms of the merger and we qualify it by reference to the
full text of the agreement. We urge all shareholders to read the merger
agreement.

         The agreement provides that:

         -        Hanover Bancorp, Inc. will be merged into Sterling Financial
                  Corporation; and

         -        Shareholders of Hanover will receive .93 shares of Sterling
                  common stock for each share of Hanover common stock owned when
                  the merger is completed.

         Hanover Bancorp, Inc. will cease to exist. The Bank of Hanover and
Trust Company and HOVB Investment Co. will be subsidiaries of Sterling Financial
Corporation. The Federal Deposit Insurance Corporation and the Pennsylvania
Department of Banking will continue to regulate The Bank of Hanover and Trust
Company.

         The Boards of Directors of Sterling and Hanover have unanimously
approved and adopted the agreement and believe the merger is in the best
interests of Sterling and Hanover, as the case may be, their shareholders and
other constituencies. The Boards of Directors of Sterling and Hanover have
unanimously recommended that shareholders vote "FOR" the agreement.

BACKGROUND OF THE MERGER

         Sterling. The Sterling Board of Directors has, for several years, as
part of its long-range planning practices, periodically reviewed and evaluated
the various strategic options and alternatives available to maximize the
economic benefits for Sterling and its shareholders. At its most recent annual
review, the board considered its long-range plan in light of current economic,
financial and regulatory conditions and their impact and likely future
ramifications for Sterling and the local financial services industry.

         In the past several years, Sterling has been able to fulfill its
strategy of expanding through acquisition of North East Bank, as well as through
internal growth in its market place and the effective management of its net
interest margin.

         The Sterling Board has long recognized that, in order for Sterling to
achieve the requisite scale and scope of operations necessary to remain an
effective competitor in the dramatically changing market for banking and
financial services, the Board should look to strategic



                                       31
<PAGE>   41
combinations with other entities that share the culture and philosophy of
Sterling with a similar commitment to long-term shareholder value and expand
through strategic acquisition

         Hanover. In the context of its ongoing evaluation of shareholder value,
and its strategic positioning of the Bank of Hanover as a community bank serving
its natural market, the Board of Directors from time to time discussed the
attraction of creating a company that could retain the inherent characteristics
of the Bank of Hanover, yet have the size and scale necessary to produce
shareholder value and compete over the long term. With this in mind, the Board
of Directors of Hanover explored various options, including acquisitions,
mergers of equals or affiliations with larger institutions, through the years,
becoming more active recently in evaluating such alternatives.

         General. Hanover and Sterling have had an ongoing business relationship
for at least five years, in which Town & Country, Inc., a Bank of Lancaster
County subsidiary, was a customer of Bank of Hanover. The two companies were
also involved in loan participations. In mid 1999, John Stefan, President of
Sterling, and Brad Scovill, President of Hanover, informally discussed
acquisition strategies, in general, and first contemplated the possibility that
Hanover and Sterling might find success in pursuing a strategic opportunity
together. In September 1999, Terrence Hormel, Chairman of Hanover, and Mr.
Scovill met with Mr. Stefan to further discuss strategies. In the following two
months, Messrs. Scovill and Stefan discussed potential structures, philosophies
and social issues regarding a potential transaction between Hanover and
Sterling.

         As part of its evaluation of its strategic alternatives, including
discussions with Sterling, Hanover's Board began to interview investment banking
firms. In November and December, 1999, following its assessment of investment
banking candidates, the Board decided to hire McConnell, Budd & Downes, Inc. In
December, the Board of Directors also retained Barley, Snyder, Senft & Cohen,
LLC to provide legal counsel in connection with its discussions, and any
possible transaction, with Sterling.

         On January 10, 2000, representatives of Sterling and Hanover, their
respective legal counsel and representatives of MB&D met to discuss the
development of an indication of interest outlining terms of a possible
affiliation between Hanover and Sterling. As a result of this meeting, Sterling,
with its legal counsel, Shumaker Williams, P.C. and investment banking firm,
Garland McPherson, developed a non-binding indication of interest and presented
it to Hanover for its consideration. The indication of interest was discussed at
a meeting of Hanover's Executive Committee of its Board of Directors held on
January 13, 2000. As a result of the meeting, the Executive Committee authorized
Hanover's management and advisors to proceed to negotiate a revised indication
of interest and forms of definitive affiliation agreements with Sterling.
Following the meeting, Messrs. Hormel and Scovill made each of the directors of
Hanover aware, on a confidential basis, of a possible transaction with Sterling.



                                       32
<PAGE>   42
         Hanover's Board of Directors met on January 21, 2000, to consider a
revised indication of interest and draft affiliation agreements. At the meeting,
management of Hanover, MB&D and Barley, Snyder made extensive presentations on
the business, financial and legal aspects of the proposed transaction.

         The Board considered these presentations in the context of Hanover's
ongoing process of exploring its various alternatives and assessing how these
alternatives would support increasing long-term shareholder value while still
maintaining Bank of Hanover as a community bank serving its natural markets. In
this context, the Board reviewed Hanover's historical relationship with Sterling
and the results of the preliminary conversations with Sterling regarding the
benefits that could be provided to shareholders, employees and customers if the
two companies joined together. The Board discussed many factors that made the
possibility of merging with Sterling attractive and that are discussed in the
"Reasons for the Merger" section, following.

           The Board discussed the proposed structure, which would allow Bank of
Hanover to remain a separate operating subsidiary and to influence Sterling's
future direction through three board seats on the holding company board.
Sterling proposed to give Hanover shareholders .93 shares of Sterling common
stock for each share of Hanover stock and to "roll over" any outstanding Hanover
stock options. Other terms of the indication of interest included:

         -        A requirement that the transaction be accounted for as a
                  pooling of interests;

         -        A multibank holding company structure with Bank of Hanover as
                  a separate subsidiary; and

         -        Termination rights of each party based on the market value of
                  Sterling stock during a period prior to closing.

         After reviewing these terms and the proposed time line for pursuing the
transaction, representatives of McConnell Budd presented a financial analysis of
the proposed transaction. Their report summarized the aggregate and per share
value of the transaction based on the current market value of Sterling stock and
the proposed consideration as a multiple of Hanover's 1999 and estimated 2000
earnings and book value. The report also contained:

         -        An extensive financial analysis of the proposed transaction,
                  including a listing of comparable banking transactions in the
                  northeastern region based on a number of measures, including
                  earnings and book value multiples;

         -        A merger model that included various "pass through" values
                  (e.g. market value, earnings power, book value and dividend
                  income) using a .93 exchange ratio and cost savings required
                  to eliminate dilution;

         -        An analysis of certain other potential acquirers' ability to
                  pay the proposed price, in terms of dilution and cost savings;

         -        A discounted cash flow analysis; and



                                       33
<PAGE>   43
         -        An analysis of the market value of Sterling's stock in
                  comparison to its peers.

         Particular note was made of the fact that Sterling's stock traded at a
higher multiple of its earnings than its peers and the risks associated with a
potential decline in the market value of its stock and a fixed exchange ratio.
Following the presentation and discussion with the Board, representatives of
MB&D indicated that they anticipated that their firm would be in a position to
render an opinion that the proposed exchange ratio is fair to the Hanover
shareholders from a financial point of view.

         A representative of Barley, Snyder then addressed the Board regarding
issues of confidentiality and emphasizing the need to refrain from trading, or
disclosing information which may lead others to trade, in the stock of Sterling
or Hanover. He also summarized the process which was proposed should the Board
authorize Hanover's management and advisors to continue to pursue the
transaction; the draft definitive agreement would continue to be negotiated;
mutual due diligence would be continued; and McConnell Budd would be asked to
finalize its "fairness opinion." Assuming these items progressed in a
satisfactory manner, a final definitive agreement would be presented to the
Boards of Sterling and Hanover and, if approved, the agreement would be executed
and the transaction would be publicly announced.

         Barley, Snyder then reviewed the directors' standard of care in
evaluating the transaction under Pennsylvania corporate law and reviewed in
detail both the indication of interest and the draft definitive agreements
received from Sterling. The review involved:

         -        The structure of the transaction;

         -        The exchange of Sterling stock for Hanover stock;

         -        Covenants of the parties between the date of the Agreement and
                  closing;

         -        Conditions to consummation of the transaction;

         -        The option to be granted to Sterling by Hanover allowing
                  Sterling to acquire up to 19.9% of Hanover's outstanding under
                  certain conditions; and

         -        The requirement that each director execute an agreement
                  agreeing to vote his shares in favor of the transaction.

Drafts of the definitive agreements were made available for review by Board
members. After considerable discussion, it was the unanimous sense of the Board
to proceed with the process through negotiation of definitive agreements and
additional due diligence.

         On January 25, 2000, Sterling's Board of Directors met to discuss the
proposed agreement relating to the acquisition of Hanover. Representatives of
Shumaker Williams and



                                       34
<PAGE>   44
Garland McPherson attended the meeting. The Board discussed the strategic impact
of the merger, counsel reviewed and analyzed terms of the proposed agreement
with Hanover including:

         -        Structure of the transaction;

         -        Consideration;

         -        Covenants of the Agreement;

         -        The 19.9% stock option granted by Hanover to Sterling; and

         -        Termination provisions.

Counsel also discussed the Board's fiduciary duties under the law. The Board
then discussed:

         -        Certain financial aspects of the proposed transaction, as
                  described in the disclosure of Garland McPherson, below.

         -        The general structure of the transaction and certain
                  pooling-of-accounting issues and tax consequences, as
                  discussed later in this proxy statement/prospectus.

         -        Messrs. Stefan, Moyer and counsel discussed the findings of
                  their due diligence review.

         -        In addition, counsel and the Board of Directors discussed the
                  continuing parameters of the insider trading blackout.

         The Board then authorized officers of the company to execute and
deliver the agreement substantially in the form presented to the Board of
Directors and reviewed by the Board of Directors.

         A meeting of Hanover's Board of Directors was held on January 25, 2000,
to review the proposed definitive agreements relating to the acquisition of
Hanover by Sterling. A representative of Barley, Snyder indicated that the
parties' management and advisors had completed their mutual due diligence, and
negotiated terms of definitive agreements to present to the Board of Sterling
and Hanover.

         Barley, Snyder then reviewed the provisions of the proposed agreement
and plan of merger, investment agreement and stock option in detail with the
Board. Barley, Snyder particularly noted and described the "market out"
termination provisions of the agreement as finally negotiated allowing Hanover
to terminate the transaction under certain circumstances relating to a decline
in the market value of Sterling's stock and providing a substantially



                                       35
<PAGE>   45
reciprocal right to Sterling in the event of an increase in the market value of
Sterling's stock. Barley, Snyder also described in some detail the exercise
events, redemption rights and termination fee provisions relating to the option
to be granted by Hanover to Sterling to acquire up to 19.9% of Hanover's stock
under certain circumstances.

         Representatives of MB&D then updated their presentation of January 21,
2000, on the financial analysis of the transaction, including the distribution
of an updated report. The report included a summary of the terms of the
affiliation, examples of the "market out" termination clauses, an updated merger
model and a written "fairness opinion" concluding that, as of the date of the
opinion, the exchange ratio was fair to the shareholders of Hanover from a
financial point of view.

         A representative of Barley, Snyder then reviewed the set of resolutions
to be presented for Board action on the definitive agreements. The Board
unanimously adopted the resolutions and Hanover and Sterling proceeded to
execute the definitive merger documents and disclosed the transaction through a
press release and SEC filing.

STERLING REASONS FOR THE MERGER

         At its meeting on January 25, 2000, the Sterling Board of Directors
unanimously determined that the terms of the agreement with Hanover were in the
best interest of Sterling, its shareholders and other constituencies. In the
course of reaching its decision to approve the agreement, the Sterling Board of
Directors consulted with:

         -        Garland McPherson & Associates, Inc.;

         -        Its legal counsel; and

         -        Independent certified public accountants.

         In reaching these conclusions, the Sterling Board considered a number
of factors, including the following:

         -        Sterling's current condition and historical operating results
                  and its prospective results of operations if Sterling were to
                  acquire Hanover, including the earnings potential of the
                  combined business;

         -        The results of operations of the resulting entity, if there is
                  realization of economies of scale over a 1-to-3 year period of
                  time;

         -        The economic, business and competitive climate for banking and
                  financial institutions in south central Pennsylvania and
                  northern Maryland and Sterling's business plan for
                  strengthening and broadening Sterling's market position in
                  this



                                       36

                  area, specifically, the ability of Sterling through this
                  transaction to enter a neighboring market with additional
                  market opportunities;

         -        The potential expansion of Sterling's non-interest revenue
                  through its leasing subsidiary, Town & Country, Inc. and Bank
                  of Lancaster County's Wealth Management Group into a new
                  market that has market characteristics that should
                  foster additional growth of these business units;

         -        The expansion of Sterling's commercial loan market into an
                  area with substantial commercial loan needs;

         -        The opportunities for Sterling to deliver its comprehensive
                  list of services and products to the Hanover customer base;

         -        The enhancement of Sterling's capital base that results from
                  this transaction that will permit the banks to pursue larger
                  loan relationships;

         -        The commitment of Hanover senior management to remain with
                  Sterling following the merger;

         -        The availability of pooling-of-interests accounting treatment
                  for the merger; and

         -        The opinion of Garland McPherson that the exchange ratio was
                  fair to the Sterling shareholders from a financial point of
                  view.

         From Sterling's standpoint, the merger represents an attractive
opportunity to acquire access to additional expertise and specialized services,
especially expanded trust services, in a broadening market area.

         The list of factors considered by Sterling is not exhaustive, but we
have highlighted the important factors considered by each Board. Individual
directors may have given different weights to these factors in reaching their
decision; however, neither the Sterling nor the Hanover Board assigned specific
weights or priority to any one factor.

HANOVER REASONS FOR THE MERGER

         In the course of reaching its decision to approve the agreement, the
Hanover Board of Directors consulted with:

         -        MB&D;

         -        Its legal counsel; and



                                       37
<PAGE>   47
         -        Its independent certified public accountant.

         The Hanover Board believes the merger is fair to, and in the best
interests of Hanover and its shareholders. In reaching these conclusions, the
Hanover Board considered a number of factors, including the following:

         -        Hanover's current condition and historical operation results,
                  and its prospective results of operations if Hanover were to
                  remain independent;

         -        The economic, business and competitive climate for banking and
                  financial institutions in the south central Pennsylvania area,
                  and the challenges that Hanover faces as an independent bank
                  in a highly competitive marker;

         -        The business, operations, earnings and prospects of Sterling,
                  and the enhanced opportunities efficiencies, particularly from
                  the integration of operations and support functions, and the
                  growth that the merger would make possible;

         -        The opinion of MB&D that the financial consideration to be
                  received in the merger was fair to Hanover shareholders from a
                  financial point of view;

         -        The experience of Sterling's senior management team; and

         -        The benefits of a tax-free exchange to Hanover shareholders.

         The list of factors considered by Hanover Board is not exhaustive, but
we have highlighted the important factors considered by the Hanover Board.
Individual directors may have given different weights to these factors in
reaching their decision; however, the Hanover Board did not assign specific
weights or priority to any one factor.

         Accordingly, the Sterling and Hanover Boards recommend that
shareholders vote FOR approval of the agreement.

EFFECT OF THE MERGER

         If the agreement is approved by the shareholders of both Sterling and
Hanover, Sterling will acquire Hanover through a merger of Hanover into
Sterling. Sterling will exchange shares of Sterling common stock for the issued
and outstanding shares of Hanover common stock. The Bank of Hanover and Trust
Company and HOVB Investment Co. will be wholly owned subsidiaries of Sterling.




                                       38
<PAGE>   48
EXCHANGE RATIO

         On the effective date of the merger, each outstanding share of Hanover
common stock will convert into the right to receive .93 shares of Sterling
common stock.

         On the effective date of the merger, each outstanding option to
purchase shares of Hanover common stock will automatically convert into an
option to purchase Sterling common stock. The number of shares of Sterling
common stock issuable upon exercise will be equal to the number of shares of
Hanover common stock subject to the option multiplied by the exchange ratio,
 .93. Shares issuable upon exercise of these options to acquire Sterling common
stock will remain subject to the terms of the plans and grant agreements of
Hanover under which Hanover issued the options.

OPINION OF STERLING INDEPENDENT FINANCIAL ADVISOR

         Sterling retained Garland McPherson, by letter dated January 4, 2000,
to render financial advisory and investment banking services including but not
limited to rendering an opinion to Sterling's Board of Directors that the
exchange ratio is fair, from a financial point of view, to its shareholders, to
Sterling in connection with the possible acquisition of Hanover. Garland
McPherson has no other material relationship with Sterling or Hanover.

         Garland McPherson, as part of its investment banking and bank
consulting business, is engaged in the valuation of financial institution
securities for a variety of purposes, including mergers and acquisitions, and
the determination of adequate consideration in merger and acquisition
transactions. The Sterling Board selected Garland McPherson on the basis of its
experience in and knowledge of the banking industry and its ability to evaluate
the fairness of the exchange ratio from a financial point of view. Garland
McPherson acted exclusively for the Sterling Board in rendering its fairness
opinion and has received fees from Sterling in rendering its fairness opinion
and its services. There are no other material relationships between Garland
McPherson, its affiliates and representatives and Sterling or its affiliates.

         The full text of the Garland McPherson opinion is attached as Annex B
to this joint proxy statement/prospectus and is incorporated herein by
reference. We urge you to read the opinion in its entirety for a description of
the procedures followed, assumptions made, matters considered and qualifications
and limitations on the review undertaken by Garland McPherson in connection
therewith. The following summary of the opinion is qualified in its entirety by
the full text of the opinion. The exchange ratio was determined by negotiation
between Sterling and Hanover and was not determined by Garland McPherson.



                                       39
<PAGE>   49
         In rendering the Garland McPherson opinion, Garland McPherson:

         -        Reviewed the historical financial performances, current
                  financial positions and general prospects of Sterling and
                  Hanover;

         -        Reviewed the agreement;

         -        Reviewed the proxy statement/prospectus;

         -        Reviewed and analyzed the stock market performance of Sterling
                  and Hanover;

         -        Studied and analyzed the operations, historical financial
                  statements and future prospects of Sterling;

         -        Reviewed the respective history of dividends paid by the two
                  institutions;

         -        Considered the terms and conditions of the proposed
                  transaction as compared with the terms and conditions of
                  comparable bank mergers and acquisitions;

         -        Discussed with various senior officers of Sterling and Hanover
                  the foregoing as well as other matters it believed relevant to
                  its opinion; and

         -        Conducted such other analyses, studies and investigations as
                  were deemed appropriate.

         Garland McPherson relied without independent verification upon the
accuracy and completeness of all the financial and other information reviewed by
and discussed with it for purposes of its opinion. With respect to the Sterling
and Hanover financial forecasts reviewed by Garland McPherson in rendering its
opinion, Garland McPherson assumed that such financial forecasts were reasonably
prepared on the basis reflecting the best currently available estimates and
judgments of the respective managements as to the future financial performance
of Sterling and Hanover. Garland McPherson did not make an independent
evaluation or appraisal of the assets (including loans) or liabilities of
Sterling or Hanover nor was it furnished with any such appraisal. Garland
McPherson also did not independently verify, and has relied on and assumed, that
all allowances for loan losses set forth in the balance sheets of Sterling and
Hanover were adequate and complied fully with all applicable law, regulatory
policy and sound banking practice as of the date of such financial statements.

         In connection with rendering the opinion, Garland McPherson performed a
variety of financial analyses. Although the evaluation of the fairness, from a
financial point of view, of the exchange ratio and of the consideration to be
paid in the transaction was to some extent a subjective one based on the
experience and judgment of Garland McPherson and not merely the result of
mathematical analysis of financial data, Garland McPherson principally relied on
the



                                       40
<PAGE>   50
financial evaluation methodology summarized below in its determinations. Garland
McPherson believes its analyses must be considered as a whole and that selecting
portions of such analyses and factors considered by Garland McPherson without
considering all such analyses and factors could create an incomplete view of the
process underlying Garland McPherson's opinion. In its analysis, Garland
McPherson made numerous assumptions with respect to business, market, monetary
and economic conditions, industry performance and other matters, many of which
are beyond Sterling's and Hanover's control. Any estimates contained in Garland
McPherson's analyses are not necessarily indicative of future results or values,
which may be significantly more or less favorable than such estimates.

         The following is a summary of selective analyses conducted by Garland
McPherson in connection with the its opinion letter.

Comparable Company Analysis

         Garland McPherson compared selected financial and operating data for
Sterling, from 1995 through September 30, 1999, with those of a peer group of
seventeen Mid-Atlantic financial institutions with assets between $700 million
and $2 billion. This data included, but was not limited to: return on average
assets, return on average equity, certain capital adequacy ratios and certain
asset quality ratios. Garland McPherson excluded securities gains and items of a
non-recurring nature in computing profitability ratios. Selected data as of
September 30, 1999 is provided below:

</TABLE>


         Garland McPherson also compared stock market data for Sterling with the
same group of banking organizations. The analysis showed, among other things,
that the average ratio of trading price to tangible book value per share for the
peer group was 199% as compared to 287% for Sterling. In addition, the group's
average stock price to core operating earnings per share was 12.3 compared to
20.1 for Sterling.

         Garland McPherson compared selected financial and operating data from
1995 through September 30, 1999 for Hanover with those of a peer group of 22
Mid-Atlantic financial institutions with assets between $250 million and $1
billion. This data included, but was not limited to: return on average assets,
return on average equity, certain capital adequacy ratios and

</TABLE>


         Garland McPherson also compared stock market data for Hanover with the
same group of banking organizations. The analysis showed, among other things,
that the average ratio of trading price to tangible book value per share for the
peer group was 158% as compared to 157% for Hanover. In addition, the group's
average stock price to core operating earnings per share was 13.0 compared to
12.2 for Hanover.

Analysis of Selected Bank Mergers

         Garland McPherson examined selected bank mergers on a nationwide basis
announced after 1998 that resulted in a market expansion for the buyer. Garland
McPherson limited the analysis to targets with total assets between $100 million
and $1 billion that generated a return on equity between 10% and 15%. The median
book multiple of these transactions was 220.6%, the median tangible book
multiple was 250.8% and the median earnings multiple was 20.9. However, none of
the companies or transactions used in any of these analyses were identical to
Hanover or to Sterling or to this transaction. Accordingly, an analysis of the
results of the foregoing is not mathematical; rather, it involves complex
considerations and judgements concerning the differences in financial and
operating characteristics of the companies and other factors that would affect
the public trading values of the companies or company to which they are being
compared.

Discounted Dividend Analysis

         Using discounted dividend analysis, Garland McPherson estimated the
present value of the future dividend streams that Hanover could produce over a
five-year period under various earnings growth assumptions. Garland McPherson
also estimated the terminal value for Hanover by applying earnings multiples
ranging from thirteen to nineteen. The dividend streams and terminal value were
discounted to determine the present value using discount rates ranging from
10.0% to 12.0%. The discounted dividend analysis indicated a range of per share
values from $21.86 to $32.18 under the most likely earnings projections.

Pro Forma Merger Analysis

         Garland McPherson examined the relative contribution that would be made
by Sterling and Hanover to various key financial statistics of the combined
entity on a pro forma basis as of December 31, 1999 before giving consideration
to any economies that may result from the merger. This analysis indicated that
the relative contributions would have been as follows:

                                                       HANOVER                                 STERLING

Total Assets                                            32.2%                                   67.8%
Gross Loans                                             31.1%                                   68.9%
Total Deposits                                          30.8%                                   69.2%
Total Equity                                            26.7%                                   73.3%
Shares Outstanding                                      28.8%                                   71.2%
</TABLE>


         Garland McPherson also analyzed, using projections derived from
discussions with managements of Hanover and Sterling, certain pro forma
projected effects resulting from the merger. The analysis indicated that, based
on the most likely earnings projections, the merger is anticipated to be neutral
in terms of the impact on Sterling's earnings per share during the second year
following the merger and accretive to earnings per share thereafter.

         In reaching its opinion as to fairness, none of the analyses performed
by Garland McPherson was assigned a greater significance by Garland McPherson
than any other. As a result of its consideration of the aggregate of all factors
present and analyses performed, Garland McPherson reached the conclusion, and
opines, that the exchange ratio, as set forth in the agreement, is fair, from a
financial point of view, to holders of Sterling's securities.

         In connection with delivering the Garland McPherson opinion, Garland
McPherson updated certain of its analyses and reviewed the assumptions on which
the analyses were based and the factors considered.

         In delivering its opinion, Garland McPherson assumed that in the course
of obtaining the necessary regulatory and governmental approvals for the
transaction, no restrictions will be imposed on Sterling or Hanover that would
have a material adverse affect on the contemplated benefits of the transaction.
Garland McPherson also assumed that there would not occur any change in
applicable law or regulation that would cause a material adverse change in the
prospects or operations of Hanover after the effective date.

         Pursuant to the terms of the engagement letter, Sterling has paid
Garland McPherson $115,000 and has agreed to reimburse Garland McPherson for its
reasonable out-of-pocket


                                       43

expenses. Sterling has also agreed to pay Garland McPherson $135,000 upon
consummation of the merger. Whether or not the Merger is consummated, Sterling
has agreed to indemnify Garland McPherson and certain related persons against
certain liabilities relating to or arising out of its engagement.

         The full text of the opinion of Garland McPherson, as of the date of
this Proxy Statement/Prospectus, which sets forth assumptions made and matters
considered, is attached hereto as Annex B to this proxy statement/prospectus. We
urge you to read the opinion in its entirety. Garland McPherson's opinion is
directed only to the consideration to be received by shareholders in the
transaction and does not constitute a recommendation to you as to how you should
vote at the meeting.

OPINION OF HANOVER INDEPENDENT FINANCIAL ADVISOR

         The Hanover Board retained MB&D under an engagement letter dated
January 24, 2000, to render financial advisory and investment banking services
to Hanover in connection with the possible acquisition of Hanover by Sterling.
MB&D has no other material relationship with Hanover or Sterling.

         On January 25, 2000, MB&D delivered its opinion to the Hanover Board of
Directors, that as of that date, the exchange ratio was fair, from a financial
point of view, to Hanover shareholders. The basis for the opinion has been
updated for the purposes of this joint proxy statement/prospectus. The opinion,
which is unchanged, appears in Annex C. The exchange ratio of .93 shares of
Sterling common stock in exchange for each share of Hanover common stock, was
negotiated based on consideration of numerous factors including the following:

         -        Analysis of the historical and projected future contributions
                  of recurring earnings by the parties.

         -        Analysis of the possible future EPS results for the parties on
                  both a combined and a stand-alone basis.

         -        Anticipated dilutive or accretive effects of the prospective
                  transaction to the earnings per share of Sterling and by
                  extension, through the exchange ratio, to earnings per share
                  equivalent of Hanover.

         -        The probable impact on dividends per share to be received by
                  Hanover shareholders as a result of the contemplated
                  transaction.

         -        Contemplation of other factors, including certain intangible

         MB&D has acted as financial advisor to Hanover since December of 1999.
With respect to the pending transaction involving Sterling, MB&D advised Hanover
during the evaluation and negotiation process leading up to the execution of the
merger agreement and provided Hanover with a number of analyses as to a range of
financially feasible exchange ratios that might be achieved in a hypothetical
transaction. Representatives of MB&D met with the executive management and Board
of Directors of Hanover or designated committees of the board on eight separate
occasions during the period from November 2, 1999 to January 25, 2000, in
connection with the analysis of Hanover's strategic alternatives and the
negotiation process. The determination of the applicable exchange ratio was
arrived at in an arms-length negotiation between Sterling and Hanover in a
process in which MB&D advised Hanover and participated directly in the
negotiations.

         MB&D was retained based on its qualifications and experience in the
financial analysis of banking and thrift institutions generally, its knowledge
of the banking markets in general and of the Pennsylvania banking markets in
particular as well as its experience with merger and acquisition transactions
involving banking institutions. As a part of its investment banking business,
which is focused exclusively on financial services industry participants, MB&D
is regularly engaged in the valuation of financial institutions and their
securities in connection with its equity brokerage business generally and
mergers and acquisitions in particular. Members of the Corporate Finance
Advisory Group of MB&D have extensive experience in advising financial
institution clients on mergers and acquisitions. In the ordinary course of its
business as a NASD broker-dealer, MB&D may, from time to time purchase
securities from or sell securities to Hanover or Sterling and as a market maker
in securities, MB&D may from time to time have a long or short position in, and
buy or sell debt or equity securities of Hanover or Sterling for its own account
or for the accounts of its customers. In addition, in the ordinary course of
business, the employees of MB&D may have direct or indirect investments in the
debt or equity securities of either or both Hanover or Sterling.

         The full text of the opinion of MB&D, which summarizes the assumptions
made, matters considered and limits on the review undertaken is attached as
Annex C. MB&D recommends that all Hanover shareholders read the joint proxy
statement/prospectus in its entirety and the opinion in its entirety. The
summary description of the matters that MB&D considered, limitations on the
review undertaken and the analyses performed and the assumptions on which



                                       45
<PAGE>   55
the various analyses are based contained in the joint proxy statement/prospectus
is more thorough and detailed than the summary contained in the opinion itself.
MB&D therefore recommends that the reader carefully study this section of the
joint proxy statement/prospectus.

         The opinion of MB&D is directed only to the exchange ratio at which
shares of Hanover common stock may be exchanged for shares of Sterling common
stock. The opinion does not constitute a recommendation to any holder of Hanover
common stock as to how such holder should vote at the Hanover annual meeting.
The opinion is necessarily based upon conditions as of the date of the opinion
and upon information made available to MB&D through the date of the opinion.

         Other than the fact that a survey or market check of companies that
could logically have been expected to have an interest in acquiring Hanover was
not performed by MB&D in conjunction with the process followed, the management
and Board of Hanover imposed no limitations on MB&D with respect to the
investigations made, matters considered or procedures followed in the course of
rendering its opinions.

                  Hanover and Sterling;

         -        Discussions with members of the senior management of Hanover
                  concerning the past and current results of operations of
                  Hanover, its current financial condition and management's

                  dividend payments for both Hanover and Sterling common stock;

         -        Based primarily on anecdotal information, the current state of
                  and future prospects for the economy of Pennsylvania generally
                  and the relevant market areas for Hanover and Sterling in
                  particular;

         -        Specific merger analysis models developed by MB&D to evaluate
                  potential business combinations of financial institutions
                  using both historical reported information and projected
                  information for both Hanover and Sterling and the results of
                  the evaluation;

         -        The reported financial terms of selected recent business
                  combinations of financial institutions for purposes of
                  comparison to the pending transaction;

         -        A survey of institutions that might have had an interest in
                  the possible acquisition of Hanover, was not completed.
                  Alternatively, an analysis of the hypothetical acquisition
                  capacity or Upstream Acquisition Analysis, as described below,
                  of a selected group of companies which MB&D believed, with the
                  concurrence of management of Hanover, would logically have
                  been interested in a possible acquisition of Hanover, was
                  completed. This analysis was based solely on publicly
                  available information concerning the companies and did not
                  involve any actual contact with the companies. MB&D believes,
                  however, that the analysis is adequate to establish a
                  reasonable range of expected values that might have been
                  available to Hanover in an unrestricted negotiation process,
                  at a point in time.



                                       47
<PAGE>   57
                  This analysis, which was updated to reflect changing market
                  conditions, was discussed with the management and the Hanover
                  Board of Directors; and

         -        Other studies and analyses as MB&D considered appropriate
                  under the circumstances associated with this particular
                  transaction.

         The opinion of MB&D takes into account its assessment of general
economic, market and financial conditions and its experience in other
transactions involving participants in the financial services industry, as well
as its experience in securities valuation and its knowledge of the banking
industry generally. For purposes of reaching the opinion, MB&D has assumed and
relied upon the accuracy and completeness of the information provided to it or
made available by Hanover and Sterling and assumes no responsibility for the
independent verification of the information. With respect to financial forecasts
made available to MB&D it is assumed by MB&D that they were prepared on a
reasonable basis and reflect the best currently available estimates and good
faith judgments of the management of Hanover and Sterling as to the future
performance of Hanover and Sterling. MB&D has also relied upon assurances of the
management of Hanover and Sterling that they were not aware of any facts or of
the omission of any facts that would make the information or financial forecasts
provided to MB&D incomplete or misleading. In the course of rendering the
opinion, MB&D has not completed any independent valuation or appraisal of any of
the assets or liabilities of either Hanover or Sterling and was not provided
with such valuations or appraisals from any other source.

         A summary of the material analyses employed by MB&D in connection with
rendering its written opinion follows. Since it is a summary, it does not
purport to be a complete and comprehensive description of all the analyses
performed, or an enumeration of every matter considered by MB&D in arriving at
the opinion. The preparation of a fairness opinion is a complicated process,
involving a determination as to the most appropriate and relevant methods of
financial analysis and the application of those methods to the particular
circumstances. Therefore, opinions are not readily susceptible to summary
description. In arriving at its fairness opinion, MB&D did not attribute any
particular weight to any one specific analysis or factor considered by it and
made a number of qualitative as well as quantitative judgments as to the
significance of each analysis and factor. Therefore, MB&D believes that its
analyses must be considered as a whole and feels that attributing undue weight
to any single analysis or factor considered could create a misleading or
incomplete view of the process leading to the formation of its opinion. In the
analyses, MB&D has made certain assumptions with respect to banking industry
performance, general business and economic conditions and other factors, many of
which are beyond the control of management of either Hanover or Sterling.
Estimates, which by definition contain the possibility of error, referred to in
the analyses are not necessarily indicative of actual values or predictive of
future results or values, which may vary significantly from those described. In
addition, analyses relating to the values of businesses do not purport to be
appraisals or to reflect the prices at which businesses might actually be sold.
Accordingly, these analyses and estimates are inherently subject to uncertainty,
and MB&D does not assume responsibility for the accuracy of these analyses or
estimates.

Analysis of the Anticipated Transaction and the Applicable Exchange Ratio in
Relation to Hanover

         The agreement provides that Hanover shareholders will receive a fixed
exchange ratio of .93 shares of Sterling common stock in exchange for each share
of Hanover common stock. The parties anticipate that the transaction will be
tax-free to those shareholders of Hanover who hold their shares as a capital
asset and that the transaction will be accounted for as a pooling of interests.

         Based on reported financial data for Hanover and Sterling as of
September 30, 1999, and earnings estimates provided by the parties, the relative
contributions of the parties to the proforma Sterling on a pooling basis would
have been approximately as follows:

      Based on reported financial data for Hanover and Sterling as of December

contributions of the parties to the proforma Sterling on a pooling basis would
have been approximately as follows:

         Based on adjusted fully converted shares and share equivalents

1999, and the negotiated exchange ratio of



                                       49
<PAGE>   59
 .93 to 1, current Hanover shareholders, had the proposed transaction been
completed as of such dates, would have owned approximately the indicated
percentage amounts of the proforma shares outstanding of Sterling depicted in
the last row of each of the above tables. A manifestation of the premium implied
in the fixed exchange ratio which applies to the pending transaction is the
difference between the prospective earnings contribution of Hanover to the
combined entity and the prospective percentage ownership of the proforma entity
by former Hanover shareholders. Hanover shareholders will prospectively receive
a larger ownership interest in the proforma entity than the relative earnings
contribution to the proforma total by Hanover in the first year of the
transaction.

Projected Transaction Value

         Based upon the exchange ratio and the last trade value of Sterling
common stock reported by NASDAQ on January 24, 2000, which was the last
completed trading day prior to the execution of the agreement, which was $27.56,
the theoretical market value of the anticipated transaction was approximately
$101.4 million as of that date, based on an estimated 3,679,269 shares of
Sterling common stock to be issued to Hanover shareholders. On a per share
basis, this is equivalent to approximately $25.63 per share ($27.56x .93). MB&D
elected to use the closing value of Sterling on this date because January 24,
2000 was the last full day of trading prior to the execution of the merger
agreement. The transaction was announced on January 26, 2000, prior to the
opening of trading on NASDAQ. Because the applicable exchange ratio is fixed,
the market value of the exchange will fluctuate as the market value of Sterling
common stock fluctuates. Based on the last trade value for Sterling common stock
reported by NASDAQ as of __________ which was $__________ on the last trading
day prior to the printing and mailing of this joint proxy statement/prospectus,
the theoretical market value of the anticipated transaction was $_______ million
as of such date, based on an updated estimate of ______________ shares of
Sterling common stock to be issued to Hanover shareholders. The indicated market
value has declined by $__________, or ___%, from the level at the announcement
date. Hanover's shareholders should take note of and understand that this value
will continue to fluctuate up and down, as the value of a share of Sterling
common stock fluctuates in the market.

Mechanics and Applicability of "Market-Out" Termination Provision

         In a pending transaction, actual or perceived circumstances may arise
that negatively impact the market value of an acquirer's common stock, whether
or not the measurable accounting reality of such a development has a material
adverse effect. It is also possible, even in the absence of any identifiable
circumstance or development, that an acquirer's common stock price can suffer a
meaningful downward adjustment. In order to provide a measure of protection to
the shareholders of Hanover against such situations, a provision of the merger
agreement (see Schedule 2.1) provides that Sterling's stock price movements
during the period measured from the date of announcement of the merger to a date
5 business days before the schedule effective date will be monitored and
compared against the starting price of Sterling common stock just before the
merger



                                       50
<PAGE>   60
was announced, which has been fixed in the merger agreement at $27.09. Hanover
shall have the right to terminate the Agreement if

         -        The closing market price of Sterling common stock, calculated
                  as the arithmetic average of the per share mean between the
                  closing bid price and the closing asked price for Sterling
                  common stock during a 20 trading day period ended 5 business
                  days prior to the Effective Date, is less than $21.67, or 80%
                  of the starting price and

         -        The closing market price divided by the starting price,
                  expressed as a percentage, is less than the Average NASDAQ
                  Bank Index Value for the same 20 day period divided by the
                  NASDAQ Bank Index Value on the starting date, which has been
                  fixed as 1516.67, also expressed as a percentage, by more than
                  5%.

         -        Alternatively, in the event that the closing market price is
                  less than $18.96, or 70% of the starting price, at the end of
                  the 20 day period, Hanover shall have the right to terminate
                  the merger agreement without reference to movements of
                  Sterling's market price relative to the NASDAQ Bank Index
                  Value.

         Sterling has reciprocal rights to terminate the merger agreement in the
event of mirroring upward movements in its stock price. In either case, the
satisfaction of the termination conditions creates a right, but not an
obligation, to terminate. The opportunity to evaluate such termination
provisions will take place only at the end of the transaction in accordance with
its terms.

         As of the date of our opinion letter included in this joint proxy
statement/prospectus, the mean of the closing bid price and closing asked price
for Sterling had declined from $27.09, which it was as of the announcement date,
to $__.__ . It has therefore declined to a level that is ____% of the starting
price. As of the date of this joint proxy statement/prospectus, we are not at
the end of the 20 day price determination period, as defined in the merger
agreement, and the termination provision is not applicable. However, if we were
at the end of the period now, Hanover would have the right, but not the
obligation, to terminate the transaction.

Multiple of Historical and Projected Earnings for Hanover Common Stock

         The cited per share theoretical value of $25.63 as of January 24, 2000,
represents a multiple of 21.18 times reported earnings per share for 1999, which
was $1.21. The $25.63 value cited is the equivalent of 18.85 times management's
internal estimate for 2000 of $1.36. Based on the closing market value for
Sterling common stock as of __________ which was $_______ and a revised
transaction value per share of $__________, the multiples of earnings were
__________ and________ times for 1999 reported EPS and management's internal
estimate for 2000 stand-alone earnings per share, respectively. The revised
multiples reflect the fact that between the time of announcement of this
prospective transaction and the date of this joint proxy statement/prospectus,
the mean between the closing bid and asked prices for Sterling common



                                       51

stock has declined approximately _____ %. The tabular information which follows

 (1)      Since public financial institutions publish earnings per share
          information on a quarterly basis, this calculation is usually
          based on annualized earnings per share based on the most
          recent four (4) quarters of reported results.

         The table above depicts a time series of LTM P/E ratios, which are
backward looking price/earnings ratios, for a selected group of financial
institutions located in New York, New Jersey and Pennsylvania. The parties
discussed an earlier version of this table, prior to the announcement of the
transaction, with management and the Hanover Board of Directors to apprize them
of the fact, that although there had then been a 15.4% reduction in the LTM P/E
ratio for Sterling Financial Corporation between September of 1998 and January
of 2000, prior to the announcement of the pending transaction, that the
reduction of Sterling's LTM P/E during this time period had been less than one
half of that of the mean reduction of the comparison group during the same time
period. The reduction in the mean LTM P/E for the comparison group for the
September 98 to January 00 time frame was 32.9% and the mean LTM P/E for the
group stood at 11.30x in January of 2000. MB&D also observed that Sterling was
trading at a 19.2x LTM P/E in January, prior to the announcement of the
transaction. In other words, Sterling was trading at a higher LTM P/E than any
other member of the comparison group. MB&D commented that, based on a theory of
rational expectations, notwithstanding the fact that Sterling has for an
extended historical period traded at a relatively elevated P/E versus other bank
holding companies, MB&D was not


                                       52
<PAGE>   62
comfortable that this pattern would persist. MB&D advised both management and
the Board that the relative P/E of Sterling should be rationally expected to
trend toward the mean of the comparison group, over time, although it would not
necessarily actually reach the mean.

         Since the announcement of the transaction on January 26, 2000, the mean
LTM P/E of the comparison group continued to trend downward and stood at 10.49x
as of April __, 2000 based on the market prices of the constituent companies on
April __, 2000 divided by their reported earnings per share for 1999. During the
same time period, the LTM P/E of Sterling has experienced a sharp negative
adjustment from 19.2x to 13.0x calculated on the same basis. Sterling's backward
looking P/E has thus declined 32.3% during the period from the announcement date
to April __, 2000 although it is still trading at a premium to the mean LTM P/E
of the comparison group.

Multiple of Stated Book Value of Hanover Common Stock

         The theoretical value of $25.63 (as of the announcement date)
represents a multiple of 3.06 times Hanover's reported $____ book value per
share as of December 31, 1999. Based on the closing market value for Sterling
common stock as of __________ which was $_______ and a revised transaction value
per share of $__________, the multiple of the December 31, 1999 book value
declined to ________.

Percentage of Market Value of Hanover Common Stock

         Based upon the theoretical values of $25.63 and $_________ for the two
relevant valuation dates, the theoretical values represent 176.76% (a 76.76%
premium) and ______% (a_____% premium) of the last reported prices for Hanover
common stock which was $14.50 on January 24, 2000.

Specific Acquisition Analysis

         MB&D employs a proprietary analytical model to examine hypothetical
transactions involving banking companies. The model uses:

         -        Forecast earnings data;

         -        Selected current period balance sheet;

         -        Income statement data;

         -        Current market;

         -        Trading information; and



                                       53
<PAGE>   63
         -        A number of assumptions as to interest rates for borrowed
                  funds, the opportunity costs of funds, discount rates,
                  dividend streams, effective tax rates, transaction structures.

The model distinguishes between purchase and pooling accounting treatments and
inquires into the likely economic feasibility of a given hypothetical
transaction at a given price level or specified exchange rate while employing a
specified transaction structure. The model also permits evaluation of various
levels of potential non-interest expense savings that might be achieved along
with various potential implementation timetables for such savings, as well as
the possibility of income enhancement opportunities that may arise in a given
hypothetical transaction.

         For the purposes of rendering the opinion with respect to this
transaction, MB&D evaluated a fixed exchange ratio of .93 shares of common stock
of Sterling in exchange for each share of Hanover in a tax deferred transaction
conditioned on the receipt of pooling accounting treatment. MB&D believes that
the nominal earnings per share dilution on a proforma basis, before
consideration of cost savings or potential income enhancements and excluding
non-recurring expenses, for Sterling would approximate 3.02% or $0.05 per share.
MB&D's calculations suggest that this transaction would be dilutive (3.45%) to
tangible book value per share on a proforma basis to Sterling based on balance
sheet information for the parties as of September 30, 1999. The transaction
would equate to a comparable deposit premium of 17.32% and would result in a
43.38% increase of dividend payments to Hanover shareholders, based on an
annualization of the most recent regular quarterly dividend payment to
shareholders by Sterling. The proforma entity will continue to be more than
adequately capitalized with a ratio of tangible common equity to tangible assets
of approximately 7.94% and an estimated tier one capital ratio in excess of
11.00%. In order for the transaction to become neutral to earnings per share
from a dilution perspective, MB&D estimates that it would be necessary to
achieve a reduction in pre-tax non-interest-expense of approximately $940,000
which represents 6.68% of the budgeted non-interest expenses for Hanover in
2000 of approximately $14 million. Because the estimation of incremental
amounts of recurring cost savings and the exact timing of their realization is
not possible for outside observers, MB&D does not attempt to forecast the future
quarter in which the pending transaction will become either earnings neutral or
accretive. It is MB&D's belief, however, that reductions in recurring
non-interest expense and earnings improvements due to the implementation of a
more diverse product line should be highly feasible for the parties involved and
that this transaction can be expected to become accretive to proforma earnings
per share with the passage of time. MB&D anticipates that this transaction will
become accretive to earnings per share of Sterling in the year 2001.

Analysis of Other Comparable Transactions

         MB&D is reluctant to place emphasis on the analysis of comparable
transactions as a valuation methodology due to what it considers to be inherent
limitations of the application of



                                       54
<PAGE>   64
the results to specific cases. MB&D believes that such analysis fails to
adequately take into consideration such factors as:

         -        Material differences in the underlying capitalization of the
                  comparable institutions which are being acquired;

         -        Differences in the historic earnings (or loss) patterns
                  recorded by the compared institutions which can depict a very
                  different trend than might be implied by examining only recent
                  financial results;

         -        Failure to exclude non-recurring profit or loss items from the
                  last twelve months' earnings streams of target companies which
                  can distort apparent earnings multiples;

         -        Material differences in the form or forms of consideration
                  used to complete the transaction;

         -        Differences between the planned method of accounting for the
                  completed transaction;

         -        Such less accessible factors as the relative population,
                  business and economic demographics of the acquired entities
                  markets as compared or contrasted to such factors for the
                  markets in which comparable companies are doing business.

         -        Comparable analysis generally cites transaction multiples and
                  premiums as of the date of announcement only and usually fails
                  to adjust such multiples and premiums for subsequent changes
                  in the trading values of the securities of the acquirer. In
                  our opinion this failure can render such comparisons, which
                  are already questionable, relatively meaningless, particularly
                  in cases where there has been a material adjustment in the
                  equity prices of financial institutions subsequent to the
                  announcement dates for such "comparable transactions". There
                  has been a virtually industry-wide downward adjustment in the
                  equity trading prices of financial institutions during the
                  last six months of 1999 and the early months of 2000 which
                  renders such announcement date comparisons more than usually
                  suspect. Consequently any use of comparable analysis requires
                  that market price adjustments must be made.

         -        Comparable analysis rarely seems to take into consideration
                  the degree of facilities overlap between the acquirer's market
                  and that of the target or the absence of such overlap and the
                  resulting cost savings opportunity differentials between two
                  otherwise apparently comparable transactions.




                                       55
<PAGE>   65
         -       Comparable analysis also generally fails to incorporate the
                 projected impact of deposit divestitures that may be required
                 by regulators in a given transaction and which are not required
                 in a so-called comparable transaction.

         For the nine reasons cited, MB&D believes that comparable analysis has
serious inherent limitations and should not be relied upon to any material
extent by members of management, the Board of Directors or shareholders in
considering the presumed merits of a pending transaction.

         With these serious reservations in mind, MB&D nonetheless examined
statistics associated with 22 transactions involving commercial banks. The
following criteria were utilized to create the sample:

         -        Acquired institutions are all commercial banks.

         -        Transactions were announced between January 1, 1997, and
                  March___, 2000.

         -        Total assets of the target institutions were greater than $300
                  million and less than $750 million.

         -        All the listed transactions took place between entities
                  located in the middle Atlantic states and/or New England.

         pooling transactions only.

         It is evident that the selected statistics, adjusted to reflect
movements in the values of the acquirer's common stock price since the
announcement dates, provide a noticeably different picture than that derived
based on such data as of the announcement date only. The comparisons remain
vulnerable to the other types of flaws listed for such analyses. The analysis
does reveal one interesting fact. Prices to tangible book ratios and price
earnings multiples have moved down sharply for the all-stock pooling
transactions examined.

         Given the listed reservations concerning the problematic nature of
comparable analysis, MB&D is willing to supply the compiled information for the
possible benefit of the Hanover shareholders but is reluctant to draw
conclusions based on such comparisons alone. MB&D is inclined to place more
weight on the other methods of analysis summarized than on comparable analysis
regardless of whether or not the apparent comparisons appear to be in favor of,
or not in favor of, a given pending transaction.

Value Pass-Through Analysis

         Value pass-through analysis is based on a comparison of anticipated
proforma values to stand-alone values as of a given point in time. Value
pass-through analysis with respect to proforma earnings per exchange unit,
proforma tangible book value per exchange unit and proforma dividends to be
received per exchange unit is unaffected by movements in the market value of the
acquirer's common stock in fixed exchange ratio transactions.

         With respect to earnings per share, based on a Hanover management
internal forecast of $1.36 in stand-alone earnings per share for 2000 and an
internal estimate of Sterling's expected earnings per share on a stand-alone
basis for the same time period, we calculated the earnings that



                                       58
<PAGE>   68
would be associated with .93 shares of proforma Sterling common stock for
2000.(1) MB&D's calculations suggest that with zero cost savings and no income
enhancements and factoring out non-recurring and transaction expenses, the
earnings associated with .93 shares of Sterling common stock would represent a
6.77% increase over the earnings associated with one share of Hanover or
approximately $1.45 per share. Assuming that exactly enough cost savings and
income enhancements can be achieved to render the transaction earnings per share
neutral, from a Sterling perspective, the earnings associated with .93 shares of
Sterling would represent a 10.10% increase over the earnings associated with a
single share of Hanover or approximately $1.50 per share. To the extent that
more cost savings and/or income enhancements are achievable, such earnings
pass-through enhancement could exceed 6.77% and 10.10%. In the event cost
savings and income enhancements that are less than the amounts necessary to
achieve earnings neutrality are achieved, the earnings associated with .93
shares of Sterling will represent an increase of between 6.77% and a greater
amount. MB&D believes that cost savings and income enhancements in excess of the
level necessary to render this transaction earnings neutral to EPS for Sterling
are reasonably achievable. The conclusion of MB&D with respect to this aspect of
the analysis is that a Hanover shareholder who exchanges his shares for Sterling
common shares at the exchange ratio of .93:1 will then hold a security which,
MB&D believes, will generate more earnings per share than the single share of
Hanover common stock that was exchanged.(2) The implication is that as long as
Sterling trades at a price earnings ratio that is equal to or greater than the
price earnings ratio at which shares of Hanover trade, the market value of the
 .93 shares of Sterling will exceed the market value of the Hanover share
exchanged.

         With respect to tangible book value per share, assuming no cost savings
and no income enhancements and factoring out non-recurring items and transaction
expenses, MB&D calculates that the tangible book value of .93 shares of the
proforma Sterling would have been $8.88 as of September 30, 1999, based on
reported tangible book values of the parties as of September 30, 1999. This
represents a conceptual 5.86% increase from the $8.38 in tangible book value per
share for Hanover as of the same date. Such an increase is generally considered
to be supportive of the market value of the exchange unit.

         With respect to dividends received per share, the estimated annualized
dividend for Hanover as of the announcement date was $0.48 per share while the
estimated annualized dividend for Sterling as of the same date was $0.74.
Consequently assuming continuation of the recent dividend policy at Sterling,
the exchange rate of .93 will confer an estimated dividend income per exchange
unit of $0.69 to Hanover shareholders. This constitutes an increase of slightly
in excess of 43%.

Upstream Acquisition Analysis

         MB&D also completed an analysis of the relative capacity of other
financial services entities doing business in, or adjacent to, Pennsylvania to
acquire Hanover on economic terms, equal to or better than, those proposed by
Sterling. We examined the theoretical ability of these entities to use a
transaction structure with similar tax and accounting implications as the
structure proposed by Sterling, a "tax-free" stock for stock exchange accounted
for as a pooling of interests. The analysis was based solely on publicly
available information concerning such other entities and no conversations were
held with either the executives or representatives of such entities. Starting
with a large universe of hypothetical acquirers that in MB&D's opinion could
theoretically have been interested in a possible acquisition of Hanover, MB&D
narrowed the list down to seven entities, excluding Sterling, for a more
detailed analysis. In examining the seven companies, the data employed was
derived from publicly available information as of September 30, 1999 and
consensus estimates for future period earnings per share obtained from Bloomberg
Financial Markets. Factors considered included:

         -        Proforma EPS dilution.

         -        Proforma tangible book value dilution.

         -        A calculation of additional after-tax earnings necessary to
                  render a given transaction earnings per share neutral to the
                  acquiring entity.

         -        A calculation of the equivalent pre-tax reduction in
                  non-interest-expense which would be necessary to render a
                  given transaction earnings per share neutral to the acquirer.

         -        Consideration of whether or not the franchise adjacency or
                  overlap, or the absence thereof, of each such hypothetical
                  acquirer would facilitate the realization of such required
                  cost savings.

         -        A value pass through analysis with respect to earnings, book
                  value and proforma dividends per share.

         -        The likely impact on trading liquidity versus existing
                  liquidity for Hanover common stock.

         As a result of MB&D analysis, MB&D reached the conclusion that of the
entities considered, Sterling would be able to complete a stock for stock
transaction at a given exchange ratio, on a basis where the amount of required
cost savings to achieve earnings per share neutrality, expressed as a pre tax
reduction in non-interest expense would be lower than such case for all of the
other entities. This is important since such a transaction contains the highest
potential for future accretive results. The conclusion which MB&D reached as a
result of its



                                       60
<PAGE>   70
upstream analysis was that there was not an obvious additional candidate which
would be able or likely to offer consideration which equaled or exceeded that
offered by Sterling.

Discounted Cash Flow Analysis I

         MB&D reviewed a discounted cash flow model that we prepared based on
projections provided by the management of Hanover. The model employed a
projection of hypothetical earnings for Hanover on an independent stand-alone
basis for calendar years 2000 through 2002. As part of the exercise, a
hypothetical dividend payout ratio assumption, which depicted average annual
payout as a percentage of earnings, was used to project dividend streams, which
would be available to shareholders. MB&D employed a range of possible future
market trading price/earnings ratios ranging from a minimum of 12 times earnings
to a maximum of 18 times earnings in order to project possible future trading
values for a share of either Hanover common stock on an independent basis or an
equivalent amount of Sterling common stock reflecting the exchange ratio. Given
the model time horizon and a range of discount rates of 12% to 14%, these
assumptions resulted in a range of present discounted values for a share of
Hanover common stock on a independent basis. Such values ranged from $16.57 to
$25.36 and include consideration of the present discounted value of the
projected stream of cash dividends, which might be received by a shareholder
during the cited period. These values represent the discounted present values of
the sum of the future possible trading values of the equivalent of one share of
Hanover common stock plus the discounted value of the stream of cash dividends
which are projected to have been received between the present and the future
valuation date at the end of 2002. The value of .93 shares of Sterling as of
January 24, 2000 exceeded the full range of present discounted values for
Hanover on a stand-alone basis.

Discounted Cash Flow Analysis II

         As has already been discussed, the market value of Sterling has
experienced a marked negative adjustment since the announcement date. As a
consequence we have revisited the discounted cash flow analysis and have revised
certain of our assumptions. Based on the broad based reduction in trading values
of the common stocks of many financial institutions during the past six month
period, we have adjusted the terminal multiple range for this model to a range
of market multiples ranging from 9 times earnings to 15 times earnings since we
believe that such a multiple range is now more representative of the actual
market for the equity securities of financial institutions. MB&D has not made an
adjustment in its range of discount rates. The model uses a projection of
hypothetical earnings for Hanover on an independent stand-alone basis for
calendar years 2000 through 2002. As part of the exercise, a hypothetical
dividend payout ratio assumption, which depicted average annual payout as a
percentage of earnings, was used to project dividend streams, which would be
available to shareholders. Apart from the change in the range of terminal market
multiples used and recognition of the decline in market trading values for
Sterling common stock, all other assumptions are unchanged. MB&D employed the
revised range of possible future market trading price/earnings ratios in order
to project possible future trading values for a share of either Hanover common
stock on an independent basis or an equivalent amount of Sterling common stock
reflecting the exchange ratio. Given the model time horizon and a range of
discount rates of 12% to 14%, MB&D's calculations generated a




                                       61
<PAGE>   71
range of present discounted values for a share of Hanover common stock on a
independent basis. Such values ranged from a minimum of $12.79 to a maximum of
$21.38 and include consideration of the present discounted value of the
projected stream of cash dividends, which might be received by a shareholder
during the cited period. These values represent the discounted present values of
the sum of the future possible trading values of the equivalent of one share of
Hanover common stock plus the discounted value of the stream of cash dividends
which are projected to have been received between the present and the future
valuation date at the end of 2002. While the value of .93 shares of Sterling as
of January 24, 2000 exceeded the full range of present discounted values for
Hanover on a stand-alone basis, the value of .93 shares of Hanover as of April
__, 2000 no longer exceeds the full range of present discounted values although
it continues to equal or exceed 75% of the range.

         The point of such a discounted cash flow exercise is not to make a
precise estimate of where Hanover on a stand-alone basis would be trading at a
precise point in the future. It is equally not an effort to predict, on a
precise basis, where the proforma Sterling will be trading at an exact point in
the future. MB&D readily acknowledges that with the large number of variables
involved including many which are beyond the control of management, that such
predictions with any degree of precision are well beyond the capability of MB&D,
Hanover or Sterling. Rather, the point of the exercise is to employ reasonable
future point earnings estimates to complete an analysis designed to test a
hypothesis that the result of one given course of action is likely to be better
over time than another. In our opinion, the results of the present discounted
cash flow analysis provides comfort that the shareholders of Hanover are likely
to be better off as a result of completing the pending transaction with Sterling
than they would likely be by remaining an independent financial institution.

         It is important to note that the discount factors we have used embody
both the concept of a time value of money and separately risk factors that
reflect, among other things, the uncertainty of the forecasted cash flows and
terminal price/earnings multiples. Use of higher discount rates would result in
lower discounted present values. Conversely, use of lower discount rates would
result in higher discounted present values. MB&D advised the Hanover board of
directors that although discounted cash flow analysis is a commonly used
valuation methodology, it relies on numerous assumptions, including discount
rates, terminal values, future earnings performance and asset growth rates, as
well as dividend payout ratios. The accurate specification of such assumptions
for time periods more than one year in the future is a very difficult process
and contains the possibility of inaccuracy despite our attempts to be both
accurate and conservative in our analysis. Consequently, any or all of these
assumptions may vary from actual future performance and results. Any errors made
in the selection of assumptions for such an exercise can interact with one
another and can lead to conclusions that may demonstrate little resemblance to
actual events.

Other Factors Given Consideration

         MB&D has given consideration to a number of additional factors
associated with the pending transaction that it believes are favorable from the
point of view of a Hanover shareholder.




                                       62
<PAGE>   72
         -        MB&D believes that the exchange ratio negotiated reflects a
                  reasonable share of ownership in the proforma Sterling for
                  Hanover shareholders based on both a historical and a
                  projected contribution analysis.

         -        MB&D has given consideration to the fact that at the present,
                  Sterling has expressed its intention to permit Bank of Hanover
                  to conduct business as such and that it has no current plan to
                  convert Bank of Hanover into branch offices of Sterling.

         -        Hanover shareholders will be initially represented by three
                  directors on the Board of Directors of Sterling.

         -        MB&D believes that the proforma entity will be a more visible
                  financial institution in the national financial markets and
                  will attract increased research coverage and generate greater
                  liquidity from a shares traded perspective than is the case
                  for either Hanover or Sterling on a stand-alone basis.
 .
         -        MB&D also believes that Hanover shareholders will encounter
                  prospects for greater future annual cash dividends based upon
                  projected cost savings and the earnings growth expectations of
                  the combined entities than would have been the case for
                  continued independence.

Compensation of MB&D

         Pursuant to a letter agreement with Hanover dated January 24, 2000,
MB&D will receive a fee for services rendered The fee has been divided into
several payments, which correspond with the successful completion of specific
events. MB&D was paid $200,000.00 after the execution of the merger agreement
for the pending transaction with Sterling and will be paid a further $250,000.00
upon issuance of its opinion to be included as an exhibit to this joint proxy
statement/prospectus. A final payment equivalent to .70% (seventy basis points)
multiplied by the value of the shares to be issued to the shareholders of
Hanover, including, conceptually, the (in-the-money) options pertaining to
Hanover shares, at the time of closing of the transaction. This final fee will
be reduced by the amount of $450,000.00 already actually paid to MB&D. In MB&D
opinion the fee arrangement is in line with industry practices for the type of
services and advice provided.

         The fee payable to MB&D represents compensation for services rendered
in connection with the analysis of the hypothetical transaction, support of the
negotiations, and participation in the drafting of documentation, and for the
rendering of the opinion. In addition, Hanover has agreed to reimburse MB&D for
its reasonable out-of-pocket expenses incurred in connection with the
transaction. Hanover also has agreed to indemnify MB&D and its directors,
officers and employees against certain losses, claims, damages and liabilities
relating to or arising out of its engagement, including liabilities under the
federal securities laws.

<PAGE>   73

         MB&D has filed a written consent with the SEC relating to the inclusion
of its fairness opinion and the reference to such opinion and to MB&D in the
registration statement in which this joint proxy statement/prospectus is
included. In giving such consent, MB&D did not admit that it comes 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, nor did MB&D thereby admit that it is an expert with
respect to any part of such registration statement within the meaning of the
term "expert" as used in the Securities Act of 1933, as amended, or the rules
and regulations of the Securities and Exchange Commission thereunder.

EFFECTIVE DATE OF THE MERGER

         The effective date of the merger will occur within 30 days following
the satisfaction or waiver of all conditions to completion of the merger
specified in the agreement. Sterling and Hanover may also mutually agree on a
different date. We presently expect that the effective date of the merger will
occur prior to June 30, 2000.

         On or prior to the effective date of the merger, Sterling will file
articles of merger with the Pennsylvania Department of State. This document will
set forth the effective date of the merger.

EXCHANGE OF HANOVER STOCK CERTIFICATES

         As promptly as practicable after the effective date of the merger,
Sterling's transfer agent, American Stock Transfer and Trust Company, will send
a transmittal form to each record owner of Hanover common stock. The transmittal
form will contain instructions on how to surrender certificates representing
Hanover common stock for certificates representing Sterling common stock.
Hanover common stock held in the Hanover Dividend Reinvestment Plan, Employee
Stock Purchase Plan and 401K plan will be exchanged directly through the
transfer agent.

         You should not forward your Hanover stock certificates until you have
received transmittal forms from Sterling. You should not return stock
certificates with the enclosed proxy card.

         Until you exchange your certificates representing Hanover common stock,
you will not receive the certificates for the Sterling common stock into which
your Hanover shares have converted.

         For all other purposes, however, each certificate that represents
shares of Hanover common stock outstanding at the effective date of the merger
will evidence ownership of the shares of Sterling common stock into which those
shares converted as a result of the merger. Neither Sterling nor Hanover will
have liability for any amount paid in good faith to a public official pursuant
to any applicable abandoned property, escheat or similar law.

                  prevailing at the time for comparable arm's length
                  transactions with other persons that do not involve more than
                  the normal risk of collectibility or present other unfavorable
                  features;

         -        Not merge with or into, or consolidate with, or be purchased
                  or acquired by, any other corporation, financial institution,
                  entity or person (or agree to any merger, consolidation,

                  practice;

         -        Not change any method, practice or principle of accounting
                  except those that may be required by generally accepted
                  accounting principles or any applicable regulation or take any
                  action that would preclude satisfaction of the condition to
                  closing relating to the pooling-of-interest method of

         -        Not open any new branches, enter into any contracts or make
                  any expenditures with respect to any new branches without the
                  prior written consent of Sterling, with the exception of the
                  branch to be located in Red Lion, Pennsylvania, the business
                  bank branch to be located in Westminster, Maryland, and the
                  relocation of the branch in New Oxford, Pennsylvania.

Hanover. In addition, the companies were involved in loan participations.

CONDITIONS TO THE MERGER

         The obligations of Sterling and Hanover to complete the merger are

agreement. The most significant of these conditions include:

         -         Approval by the shareholders of Sterling and Hanover;

         -         Approval by, notice to or consent of the Board of Governors

         -         Receipt of an opinion of Shumaker Williams, P.C. concerning
                   certain federal income tax consequences relating to the

                   pooling of interests for financial reporting purposes;

         -         Determination of compliance with all applicable federal and
                   state securities and antitrust laws; and

         -         Dissenting shareholders exercise of dissenters' rights with
                   respect to no more than 5% of the issued and outstanding
                   shares of Sterling common stock and 6% of the issued and
                   outstanding shares of Hanover common stock.

         In connection with the regulatory approvals, Sterling will file:

         -         A Notice with respect to the transaction with the Board of
                   Governors of the Federal Reserve System, pursuant to the Bank
                   Holding Company Act; and

         -         An Application with the Pennsylvania Department of Banking,

         Any term or condition of the agreement may be waived by the party that
would benefit from the term at any time before the merger, whether before or
after the approval of the agreement by Sterling's or Hanover's shareholders.
However, the parties may not adopt a change in the

                                       67
<PAGE>   77
amount of consideration to be received by Hanover shareholders unless the
shareholders of Hanover approve the change. In addition, if the parties waive
the requirement that a tax opinion be delivered at closing and the tax
consequences to the Hanover shareholders are material, Hanover would send
revised materials to shareholders and solicit their approval.

INVESTMENT  AGREEMENT

         Concurrently with the execution and delivery of the agreement, Sterling
and Hanover entered into an investment agreement. The investment agreement is
attached as Exhibit A to the agreement, which is attached to this joint proxy
statement/prospectus as Annex A. The investment agreement protects Sterling from
interference from a third party during the period of time between execution of
the agreement and merger of the companies.

         Under the terms of the investment agreement Hanover granted Sterling an
option to purchase up to 772,995 shares of Hanover common stock at a purchase
price of $14.00 per share. However, Sterling may not exercise the option for
more than 19.9% of the issued and outstanding shares of Hanover after giving
effect to the option exercise.

         The option is exercisable upon the occurrence of the following events:

         -         The failure of Hanover's shareholders to approve the merger

         -         A third party's acquisition of 20% or more of Hanover's
                   common stock, exclusive of any of Hanover's common stock sold
                   to the third party, directly or indirectly, by Sterling;

         -         A third party beginning a tender or exchange offer for
                   Hanover's common stock, or applied to a bank regulatory
                   authority, that would result in the third party acquiring or
                   having the right to acquire 20% or more of the issuer's
                   common stock; or

         -         A third party's entrance into an acquisition agreement with
                   Hanover.

         Sterling may exercise the option for some or all of the shares.

         The Investment also grants redemption rights to Sterling These rights
permit Sterling to require the company to redeem some or all of the shares
acquired by Sterling upon exercise of the warrant at a redemption price equal
to:

         -         115% of the exercise price;

         -         The highest price paid or agreed to be paid for a share of
                   stock by an acquiring person, as defined; and

                                       68
<PAGE>   78
         -         In the event of sale of all or substantially all of the
                   company's assets, the sum of the price paid for the assets
                   and the current market value the remaining assets of the
                   company, as determined by a recognized banking firm, divided
                   by the number of shares of common stock then outstanding.

         The redemption rights are exercisable upon the occurrence of either of
the following events:

         -         Third party acquisition of 20% or more of the Hanover common
                   stock, exclusive of any shares resulting from the exercise of
                   the warrant or shares of Hanover common stock sold by
                   Sterling; or

         -         Third party agreement to acquire Hanover by any method.

         In addition, the investment agreement provides for adjustment of the
option in the event of a change in the Hanover common stock through a stock
dividend, stock split, recapitalization, combination, conversion, division, or
exchange of shares. In each case, the number and kind of shares issuable under
the option is adjusted appropriately.

TERMINATION OF THE MERGER AGREEMENT

         The agreement may be terminated at any time before the merger, whether
before or after its approval and adoption by the shareholders of Hanover by:

         -         Agreement of all of the parties;

         -         Unilateral action by each of the parties in the event of a
                   material breach by the other party of any representation,
                   warranty or covenant not cured or curable within 30 days
                   after written notice or any condition precedent to the
                   terminating party's obligation to consummate the merger is
                   not satisfied through no fault of the terminating party;

         -         By either party in the event of a failure to consummate the
                   merger by September 30, 2000; or

         -         By Sterling, if under circumstances described in Section
                   7.1(e) of the agreement, Hanover is involved in a merger or
                   other transaction with any other party or another party makes
                   an offer or a proposal to acquire 20% of Hanover capital
                   stock.

         The merger agreement contains provisions allowing Hanover or Sterling
to terminate the agreement in the event of a substantial decline or increase in
the market value of Sterling's common stock from its level immediately prior to
the execution of the agreement. These

                                       69
<PAGE>   79
provisions provide either party with the right, but not the obligation, to
terminate the agreement; this right of termination only exists immediately
before the scheduled closing date of the merger. In the case of Hanover, these
provisions are designed to protect it from a substantial decline in the market
value of Sterling's common stock that results from either a development directly
relating to Sterling, but which does not trigger any other termination right, or
from factors unrelated to Sterling itself, such as a general downward movement
of the stock markets or particular segments of the stock markets.

         The merger agreement sets forth two tests relating to the market value
of Sterling's common stock under which Hanover has the right to terminate the
agreement in the event the conditions of either test are met. To apply these
tests, the "closing market price" of Sterling's common stock is determined by
calculating the arithmetic average of the per share mean between the closing bid
price and the closing asked price for Sterling common stock during a 20 day
trading period ending 5 days prior to the scheduled closing of the merger. The
first test is a two-pronged test under which Hanover may terminate the merger
agreement if:

         -         Sterling's "closing market price" is less than 80% of the
                   market price of Sterling's stock on the day prior to
                   announcement of the transaction; that market price was
                   $27.09, and 80% of that market price equals, $21.67; and

         -         The decline in Sterling's market price, exceeds the decline
                   in the NASDAQ Bank Index Value between the day the starting
                   price is determined and the end of the 20 day period, by more
                   than 5%. For purposes of this calculation:

         -         The percentage decline in Sterling's market price is
                   calculated by dividing the closing market price by the
                   starting price of $27.09;

         -         The percentage decline in the NASDAQ Bank Index is calculated
                   by dividing the 20 day average NASDAQ Bank Index, during the
                   closing period, by the starting NASDAQ Bank Index Value of
                   1516.67.

         The second test has only once requirement:

         -         Hanover has the right to terminate the merger agreement if
                   the closing market price of Sterling's common stock is less
                   than 70% of the starting price, regardless of the movement of
                   the NASDAQ Bank Index Value. Seventy percent of the starting
                   price is $18.96.

         As we describe above, the Sterling market price termination provisions
apply during a period immediately prior to closing of the merger. Thus, neither
party has the right to terminate the agreement under the Sterling market price
termination provisions at this time. However, for the 20 day trading period
ended on April _____, 2000, the mean of the closing bid and closing asked price
for Sterling stock was $__________, a decline of _____%. The NASDAQ Bank Index
Value declined _____% during the period from the day the starting price was
determined to April _____, 2000. Thus, if the closing market price of Sterling
stock was determined during the



                                       72
<PAGE>   82
20 trading day period ended on April _____, 2000, Hanover would have the right
to terminate the merger agreement under either test.

         We anticipate that the merger will close late in the second quarter of
2000. Neither Hanover nor Sterling can predict whether the market price of
Sterling's stock or the NASDAQ Bank Index Value will increase, decrease or
remain stable between the date of this proxy statement/prospectus and the end of
the period during which the closing market price is determined. However, if
either test is met allowing Hanover to terminate the merger agreement based on
the market value of Sterling's stock, Hanover's Board of Directors would
determine, as of the relevant date, in the exercise of its fiduciary duties,
whether the transaction remains in the best interests of Hanover's shareholders,
employees, customers, the communities it serves and Hanover's other
constituencies. This determination would be made by Hanover's Board in light of
all the facts and circumstances that exist at the time. Hanover's Board expects
to employ the same methodology it used and examine the same factors it
considered when it originally approved the merger agreement. Many of the
factors, including financial factors, originally considered by the Board in
approving and adopting the merger agreement were independent of the market price
of Sterling's stock. Thus, the market price of Sterling's common stock, in and
of itself, may not be determinative in the Board's decision. Among the
non-financial factors which Hanover's Board considered in approving and adopting
the merger agreement were the following:

         -         Sterling's financial performance, including its historical
                   return on equity and earnings per share, and capital
                   position;

         -         Sterling's credit quality, community banking philosophy,
                   geographic market and progressive view of the future of
                   financial services;

         -         Sterling's non-banking businesses, including leasing,
                   investment services and insurance;

         -         Sterling's size, market capitalization and stock liquidity;

         -         The consistent management philosophies and cultures of
                   Hanover and Sterling; and

         -         The profile of the resulting company in terms of assets,
                   market capitalization, stock liquidity, legal lending limit,
                   investment assets under management, contiguous markets and
                   management resources.

         As part of the process of evaluating whether to terminate the merger
agreement, Hanover's Board would expect to consult with McConnell Budd to review
an updated analysis of the financial factors that the Board originally
considered, including the market for financial institution merger transactions
at that time. In addition to the multiple of the merger price based on market
value to earnings, other financial factors that would be considered include:




                                       73
<PAGE>   83
         -         Relative ownership percentages of the Hanover and Sterling
                   shareholders in the institution resulting from the merger;

         -         Book value multiples;

         -         A merger model which includes various "pass through" values
                   (e.g. market value, earnings power, book value and dividend
                   income) using a .93 exchange ratio and cost savings required
                   to eliminate dilution;

         -         An analysis of certain other potential acquirers' ability to
                   pay the proposed price, in terms of dilution and cost
                   savings, although no discussions were held with such parties;

         -         A discounted cash flow analysis; and

         -         An analysis of the market value of Sterling's stock in
                   comparison to its peers.

         The input sought from McConnell Budd would likely include a
determination of whether McConnell Budd continues to believe the exchange ratio
is fair to Hanover's shareholders from a financial point of view. However, it
should be noted that the availability of an updated fairness opinion and the
determination as to whether to exercise Hanover's termination right based on the
market value of Sterling stock are not directly related. For example, a
situation could exist in which such a fairness opinion is available but the
Board of Directors determines it is in the best interests of Hanover and its
constituencies to exercise its right of termination.

         We reiterate that if the closing market price of Sterling's common
stock were to be determined during the 20 trading days ending on the date of
this proxy statement/prospectus, Hanover would have the right, but not the
obligation, to terminate the merger agreement under either of the tests
described above. No determination can be made as to whether Hanover's Board
would have the right to terminate the merger agreement until immediately before
the scheduled closing of the merger, and no determination can be made at this
point as to whether the Board would exercise that right. Therefore, in voting
whether to approve the merger agreement, Hanover's shareholders should not
assume that the Board would exercise a right to terminate if it were available.

CHANGE OF CONTROL FEE

         If Hanover or Bank of Hanover enters into a change of control
transaction:

         -         Within 60 days after termination of the agreement according
                   to its terms,

         -         Sterling has not breached its obligations under the
                   agreement,

                                       74
<PAGE>   84
then, Hanover will pay a $500,000 fee to Sterling, in addition to paying
Sterling's expenses relating to the merger. For purposes of this termination
fee, a change in control is defined as:

         -         A merger, consolidation or division,

         -         A sale, exchange, transfer or other disposition of
                   substantially all of Hanover's assets,

         -         Hanover's purchase of another entity unless the Hanover
                   shareholders control at least a majority of the votes
                   entitled to be cast for the election of directors or

         -         A transaction having an effect similar to those described in
                   the agreement.

EMPLOYEE BENEFITS

         Sterling and Hanover agreed to use their best efforts to employ as
officers and employees of Hanover immediately following the merger, any persons
who were officers and employees of Hanover immediately before the merger.
Employment in these circumstances will be on an "at will" basis. As a condition
to employment by Sterling or Hanover, any continuing employee must agree to
cancel any existing employment contract, agreement or understanding now in
existence with Hanover or Bank of Hanover.

         After the merger, all benefits of continuing Hanover employees will be
maintained at a level at least equal to the benefits enjoyed by those employees
prior to the merger. Sterling's and Hanover's Board of Directors will determine
changes to compensation and benefits in the future as may be appropriate. After
the merger, continuing Hanover employees will be eligible to apply for positions
available at Sterling or any of its subsidiaries. Sterling will also permit
severance payments to employees of Bank of Hanover, other than to employees who
severance benefits were provided for and written in employment agreements or
whose employment is terminated within six months following the merger. Those
individuals will need to sign a release of any and all claims the individual may
have against Hanover, Bank of Hanover, Sterling or any Sterling affiliate.

MANAGEMENT AND OPERATIONS FOLLOWING THE MERGER

         Sterling will employ and retain Hanover's senior executive officers,
who are employed, in good standing and actively at work on the day of the
merger, in their current management positions, with compensation initially at
least equal to their current levels of compensation. In the future, Sterling's
and Bank of Hanover's Board of Directors will determine any changes to
employment status, compensation and benefits as may be appropriate. Sterling
retains the right to terminate any of the continuing officers at any time
following the date of the merger for "good reason," as that term is reasonably
defined by Sterling.


                                       75
<PAGE>   85
         John E. Stefan, President and Chief Executive Officer of Sterling, will
join the Bank of Hanover Board of Directors following the merger. Non-employee
directors' compensation for services as a member of the Bank of Hanover Board of
Directors will remain the same for a period of 3 years after the effective date.
Individuals serving on the Bank of Hanover Board of Directors immediately
following the effective date of the merger shall, absent a breach of a
director's fiduciary duty, be nominated and recommended by Sterling's Board of
Directors to serve 3 successive 1 year terms, and to serve until the director's
successor has been duly elected, qualified or appointed.

         Three people, as Sterling and Hanover agree, will be appointed to the
Sterling Board of Directors and one individual will be appointed to the Board of
Directors of Bank of Lancaster County. Sterling's Board of Directors will elect
J. Bradley Scovill, President and Chief Executive Officer of Hanover, as
President and Chief Executive Officer of Bank of Hanover and as an Executive
Vice President of Sterling. Sterling's Board of Directors will also appoint Chad
M. Clabaugh as Executive Vice President of Bank of Hanover and Vice President of
Sterling. Messrs. Scovill and Clabaugh will also be members of the Sterling
Management Committee.

FEDERAL INCOME TAX CONSEQUENCES

         The following discussion summarizes the anticipated material federal
income tax consequences of the merger, if the merger were to take place on the
date of this proxy statement/prospectus. This is only a general description. We
include the opinion of Shumaker Williams, P.C., Special Counsel to Sterling, as
to the income tax consequences of the merger as Exhibit 8 to the Registration
Statement of which this proxy statement forms a part. Shumaker Williams assumed
that the merger and related transactions will take place as described in the
agreement. The opinion does not consider the particular facts and circumstances
of your situation. We recommend that you consult your own tax advisors as to
particular facts and circumstances that may be unique to you and not common to
shareholders as a whole, and also as to any estate, gift, state, local or
foreign tax consequences arising out of the transactions and/or any sale of
Sterling common stock received in the merger. We do not anticipate that the law
will change before completion of the merger.

         The following is a summary of the opinion of Shumaker Williams, P.C.:

         -         The merger will be treated for federal income tax purposes as
                   a reorganization within the meaning of Section 368(a)(1)(A)
                   of the Internal Revenue Code;

         -         Neither Hanover nor Sterling will recognize gain or loss in
                   the merger;

         -         Shareholders of Hanover will not recognize any gain or loss
                   upon their receipt of Sterling common stock in exchange for
                   their Hanover common stock, except shareholders who receive
                   cash proceeds received for fractional interests will
                   recognize gain or loss equal to the difference between the
                   proceeds and the tax




                                       76
<PAGE>   86
                   basis allocated to their fractional share interests, and the
                   gain or loss will constitute capital gain or loss if their
                   Hanover common stock is held as a capital asset at the
                   effective date of the merger;

         -         The tax basis of the shares of Sterling common stock,
                   including fractional share interests, that Hanover
                   shareholders receive in the merger will be the same as the
                   tax basis of their original shares of Hanover common stock
                   exchanged for Sterling less any basis allocable to fractional
                   share interests; and

         -         The holding period of the Sterling common stock Hanover
                   shareholders receive in the merger will include the holding
                   period of their original shares of Hanover common stock,
                   provided they hold their Hanover common stock as a capital
                   asset at the time of the merger.

         This is not a complete description of all the federal income tax
consequences of the merger and, in particular, does not address tax
considerations that may affect the treatment of shareholders who acquired their
Hanover common stock pursuant to the exercise of employee stock options or
otherwise as compensation, or shareholders that are exempt organizations of who
are not citizens or residents of the United States. Your individual
circumstances may affect the tax consequences of the merger to you. In addition,
we have not provided with respect to the tax consequences of the merger under
applicable state, local or foreign laws. We urge you to consult a tax advisor as
to the specific tax consequences of the merger to you.

ACCOUNTING TREATMENT

         The agreement contemplates that the merger will be treated as a pooling
of interests for financial accounting and reporting purposes. Under this
accounting method, the assets and liabilities of Hanover will be combined with
Sterling at their historical recorded bases. Results of operations of Sterling
will include the results of both companies for the entire fiscal year in which
the merger occurs. The reported balance sheet amounts and results of operations
of the separate companies for the prior periods will be combined, reclassified
and conformed, as appropriate, to reflect the combined financial position and
results of operations for Sterling.

         If Sterling would be required to purchase more than 10% of the
outstanding shares of Hanover capital stock for cash due to the exercise of
dissenters' rights by Hanover shareholders, or if other conditions arise that
would prevent the merger from being treated as a pooling-of-interests for
financial accounting purposes, Sterling has the right to terminate the agreement
and to cancel the merger.


                                       77
<PAGE>   87
EXPENSES

         Sterling and Hanover will each pay all their respective costs and
expenses, including fees and expenses of financial consultants, accountants and
legal counsel, except that Sterling and Hanover will share proportionally the
cost of printing this proxy statement.

RESTRICTION ON RESALE OF STOCK HELD BY AFFILIATES

         The shares of Sterling common stock to be issued upon completion of the
merger have been registered with the Commission under the Securities Act.
Following the merger, these shares may be freely resold or otherwise transferred
by all former shareholders of Hanover, except those former shareholders who are
deemed "affiliates" of Hanover, within the meaning of Commission Rules 144 and
145. In general terms, any person who is an executive officer, director or 10%
shareholder of Hanover at the time of the meeting may be deemed to be an
affiliate of Hanover for purposes of Commission Rules 144 and 145. This proxy
statement/prospectus does not cover resales of shares of Sterling common stock
to be issued to affiliates of Hanover in connection with the transaction.

         Sterling common stock received by persons who are deemed to be
affiliates of Hanover may be resold only:

         -         In compliance with the provisions of Commission Rule 145(d);

         -         In compliance with the provisions of another applicable
                   exemption from the registration requirements of the
                   Securities Act; or

         -         Pursuant to an effective registration statement filed with
                   the Commission.

         In general terms, Commission Rule 145(d) permits an affiliate of
Hanover to sell shares of Sterling common stock he or she received in ordinary
brokerage transactions subject to certain limitations on the number of shares
that may be sold in any consecutive three month period.

         The ability of affiliates to resell shares of Sterling common stock
received in the transaction under Rule 144 or Rule 145, is subject to Sterling's
having satisfied its Exchange Act reporting requirements for specified periods
prior to the time of sale. Affiliates are also permitted to resell Sterling
common stock received in the transaction pursuant to an effective registration
statement under the Securities Act or another available exemption from the
Securities Act regulations and requirements. This proxy statement/prospectus
does not cover any resales of Sterling common stock received by persons who may
be deemed to be affiliates of Sterling or Hanover.

         Each person who may be an affiliate of Hanover is required, prior to
the closing, to provide Sterling with a letter agreeing to abide by the
limitations imposed by the Commission



                                       78
<PAGE>   88
regarding the sale or other disposition of the shares of Sterling common stock
that the shareholders will receive in the merger.

         In addition, a requirement of pooling-of-interests accounting treatment
for the merger is that an affiliate of Hanover may not, as a general rule and
subject to an exception in a case of certain de minimis sales:

         -         Sell any shares of Hanover common stock during the 30-day
                   period immediately preceding the day of the merger; or

         -         Sell any shares of Sterling common stock received by him or
                   her in exchange for his or her shares of Hanover capital
                   stock until after the publication of financial results
                   covering at least 30 days of post-merger combined operations.

FINANCIAL INTERESTS OF DIRECTORS AND OFFICERS

         Certain members of management of Hanover and its Board of Directors,
may have interest in the merger in addition to their interests as shareholders.

         On January 25, 2000, Mr. Scovill entered into an employment agreement
with Sterling Financial Corporation and the Bank of Hanover which will only take
effect on the effective date of the merger. Under the terms of the agreement,
Mr. Scovill will be employed as Executive Vice President of Sterling and
President and Chief Executive Officer of Bank of Hanover. The term of the
Agreement is three years, beginning on the effective date of the merger between
Sterling and Hanover. On each anniversary date of the employment agreement, the
term of the agreement is extended for an additional year so that the term of the
employment agreement is a full three years each time it is renewed, unless
either Mr. Scovill or the Bank of Hanover or Sterling indicates that they do not
wish to extend the term.

         The employment agreement allows the Bank of Hanover or Sterling to
terminate Mr. Scovill's employment for cause. The agreement automatically
terminates if Mr. Scovill becomes disabled or terminates his employment other
than for good reason or because of a change in control. Following a change in
control of either Sterling or Bank of Hanover, Mr. Scovill would be entitled to
receive 2.99 times his annual compensation at the time of the change in control.
In addition, his life, disability and other welfare benefits will be continued
for three years following the change in control or until he obtains other
employment which provides substantially similar benefits. If Mr. Scovill's
employment is terminated by the Bank of Hanover or Sterling without cause, and
no change in control has occurred, Mr. Scovill is entitled to receive 2 times
his annual salary or the remaining balance of his compensation otherwise due to
him through the end of the existing term of the employment agreement, whichever
is greater. In addition, Mr. Scovill will continue to receive life, disability,
medical insurance and other normal health and welfare benefits for the remainder
of the current term of the employment agreement or the cost of such benefits in
cash. He would also be entitled to receive additional retirement benefits which
he otherwise


                                       79
<PAGE>   89
would have received if his employment had continued through the end of the term
of the employment agreement.

         The agreement also provides that Sterling and Bank of Hanover will
obtain insurance covering Mr. Scovill against lawsuits, arbitrations and similar
legal proceedings in his capacity as an officer of Sterling and Bank of Hanover.
In addition, Sterling has agreed to indemnify Mr. Scovill for legal proceedings
brought against him because of his service as a director, officer, employee or
agent of Sterling.

         In addition, Chad M. Clabaugh and Thomas J. Paholsky will be offered
change in control agreements. Under the change in control agreements, in
addition to terms standard to such agreements, it is anticipated that each of
Messrs. Clabaugh and Paholsky would be entitled to receive a multiple of his
average annual compensation in the event that he terminates his employment for
good reason following a change in control of the Bank of Hanover or Sterling.
However, he would not be entitled to receive this payment if he was terminated
for cause. In addition, it is anticipated that the change in control agreement
would terminate if he voluntarily left his employment, retired, died or became
disabled.

         The Hanover Board of Directors was aware of these factors and
considered them, among other matters, in approving the merger agreement.

         The directors and officers of Sterling and its subsidiaries have no
special interests in the merger, other than in their capacity as shareholders of
Sterling. The directors and officers of Sterling and its subsidiaries will not
receive any special consideration or compensation in connection with the
completion of the merger.

DISSENTERS' RIGHTS

         General. The Pennsylvania Business Corporation Law of 1988, grants
shareholders of Sterling and of Hanover the right to dissent from the merger and
to obtain payment of the "fair value" of their shares in the event we complete
the merger.

         If you are a shareholder of Sterling or Hanover and you contemplate
exercising your right to dissent, we urge you to read carefully the provisions
of Subchapter D of Chapter 15 of the Pennsylvania Business Corporation Law of
1988, which is attached to this proxy statement/prospectus as Annex D. We
include a discussion of the provisions of the statute. The discussion describes
the steps that you must take if you want to exercise your right to dissent.
You should read this summary and the full text of the law.

         Before the day of the shareholders meeting, send any written notice or
demand, required concerning your exercise of dissenters' rights to Ronald L.
Bowman, Vice President/Secretary, Sterling Financial Corporation, 101 North
Pointe Boulevard, Lancaster, Pennsylvania 17601, if




                                       80
<PAGE>   90
you are a Sterling shareholder, or Thomas J. Paholsky, Secretary, Hanover
Bancorp, Inc., 33 Carlisle Street, Hanover, Pennsylvania 17331, if you are a
Hanover shareholder.

         Fair Value. The term "fair value" means the value of a share of
Sterling or, if you are a Hanover shareholder, Hanover common stock immediately
before the day of the merger, taking into account all relevant factors, but
excluding any appreciation or depreciation in anticipation of the merger.

         Notice of Intention to Dissent.  If you wish to dissent, you must:

         -         File a written notice of intention to demand payment of the
                   fair value of your shares if the merger is effected with
                   Sterling or Hanover, prior to the vote of shareholders on the
                   merger at the meeting;

         -         Make no change in your beneficial ownership of stock from the
                   date you give notice through the day of the merger; and

         -         Not vote your stock for approval of the agreement.

         Neither a proxy nor a vote against approval of the merger satisfies the
necessary written notice of intention to dissent.

         Notice to Demand Payment. If the merger is approved by the required
vote of shareholders, Sterling or Hanover will mail a notice to all dissenters
who gave due notice of intention to demand payment and who did not vote for
approval of the agreement. The notice will state where and when you must deliver
a written demand for payment and where you must deposit certificates for stock
in order to obtain payment. The notice will include a form for demanding payment
and a copy of the law. The time set for receipt of the demand for payment and
deposit of stock certificates will be not less than 30 days from the date of
mailing of the notice.

         Failure to Comply with Notice to Demand Payment, etc. You must take
each step in the indicated order and in strict compliance with the statute to
keep your dissenters' rights. If you fail to follow the steps, you will lose
your right to dissent and you will receive .93 shares of Sterling common stock
for each share of Hanover common stock that you hold or, if you are a Sterling
shareholder, you will continue to hold Sterling common stock after the merger.

         Payment of Fair Value of Shares. Promptly after the merger, or upon
timely receipt of demand for payment if the merger already has taken place,
Sterling will send dissenters, who have deposited their stock certificates, the
amount that Sterling estimates to be the fair value of the stock. The remittance
or notice will be accompanied by:





                                       81
<PAGE>   91
         -         A closing balance sheet and statement of income of Sterling
                   or Hanover for a fiscal year ending not more than 16 months
                   before the date of remittance or notice together with the
                   latest available interim financial statements;

         -         A statement of Sterling's estimate of the fair value of the
                   Sterling common stock or Hanover common stock; and

         -         A notice of the right of the dissenter to demand supplemental
                   payment, accompanied by a copy of the law.

         Estimate by Dissenter of Fair Value of Shares. If a dissenter believes
that the amount stated or remitted by Sterling is less than the fair value of
the stock, the dissenter may send an estimate of the fair value of the stock to
Sterling. If Sterling remits payment of the estimated value of a dissenter's
stock and the dissenter does not file his or her own estimate within 30 days
after the mailing by Sterling of its remittance, the dissenter will be entitled
to no more than the amount remitted by Sterling.

         Valuation Proceeding. If any demands for payment remain unsettled
within 60 days after the latest to occur of:

         -         The merger;

         -         Timely receipt by Sterling or Hanover, as the case may be, of
                   any demands for payment; or

         -         Timely receipt by Sterling or Hanover, as the case may be, of
                   any estimates by dissenters of the fair value,

then, Sterling may file an application, in the Court of Common Pleas of
Lancaster County, requesting that the court determine the fair value of the
stock. If this happens, all dissenters, no matter where they reside, whose
demands have not been settled, shall be made parties to the proceeding. In
addition, a copy of the application will be delivered to each dissenter.

         If Sterling fails to file the application, then any dissenter, on
behalf of all dissenters who have made a demand and who have not settled their
claim against Sterling, may file an application in the name of Sterling at any
time within the 30-day period after the expiration of the 60-day period and
request that the Lancaster County Court determine the fair value of the shares.
The fair value determined by the Lancaster County Court may, but need not, equal
the dissenters' estimates of fair value. If no dissenter files an application,

fair value of the common stock and no more, and may bring an action to recover
any amount not previously remitted, plus interest at a rate the Lancaster County
Court finds fair and equitable.

         Sterling intends to negotiate in good faith with any dissenting
shareholders. If, after negotiation, a claim cannot be settled, then Sterling
intends to file an application requesting that the fair value of the common
stock be determined by the Lancaster County Court.

         Costs and Expenses. The costs and expenses of any valuation proceedings
in the Lancaster County Court, including the reasonable compensation and
expenses of any appraiser appointed by the Court to recommend a decision on the
issue of fair value, will be determined by the Court and assessed against
Sterling except that any part of the costs and expenses may be apportioned and
assessed by the Court against all or any of the dissenters who are parties and
whose action in demanding supplemental payment the Court finds to be dilatory,
obdurate, arbitrary, vexatious or in bad faith.

dividends are expected for the foreseeable future to be obtained exclusively
from dividends paid to Hanover by its bank subsidiary.

Anti-takeover Provisions

         The articles of incorporation and bylaws of Hanover include certain
provisions which may be considered to be anti-takeover in nature, in that they
may have the effect of discouraging or making more difficult the acquisition of
control over Hanover by means of an unsolicited tender or exchange offer, proxy
contest or similar transaction. The provisions in the articles of incorporation
of Hanover which may be so considered include the following:

         -        A provision which provides for substantial authorized but
                  unissued capital stock, including a class of preferred stock
                  whose rights and privileges may be determined prior to
                  issuance by the Hanover Board of Directors;

         -        A provision which denies to shareholders the right to cumulate
                  their votes in the election of directors;

         -        A provision which establishes criteria to be applied by the
                  Board of Directors in evaluating an acquisition proposal;

         -        A provision which requires a greater than majority vote in
                  order to remove a director or to fill a vacancy caused by such
                  a removal or to amend certain provisions of the articles of
                  incorporation and bylaws;

         -        A provisions which requires a greater than majority
                  shareholder vote in order to approve certain business
                  combinations and other extraordinary corporate transactions;
                  however, if a greater than majority of the Directors has
                  approved the transaction, only a majority shareholder vote is
                  required; and


                                       93
<PAGE>   103
         -        A provision that eliminates the right of shareholders to call
                  a special meeting.

         The provisions of the bylaws of Hanover which may be considered to be
anti-takeover in nature include the following:

         -        A provision which limits the permissible number of directors;

         -        A provision which establishes a classified Board of Directors
                  with staggered three year terms;

         -        A provision which prevents certain bylaws provisions from
                  being amended except by a greater than majority shareholder
                  vote; and

         -        A provision that requires advance written notice as a
                  precondition to the nomination of any person for election to
                  the Board of Directors, other than in the case of nominations
                  made by existing management.

         As a Pennsylvania business corporation and a corporation registered
under the Securities Exchange Act of 1934, Hanover is subject to, and may take
advantage of the protections of, the antitakeover provisions of the Pennsylvania
Business Corporation Law. These antitakeover provisions, which are designed to
discourage the acquisition of control over a targeted Pennsylvania business
corporation, include:

         -        A provision whereby the directors of the corporation, in
                  determining what is in the best interests of the corporation,
                  may consider factors other than the economic interests of the
                  shareholders, such as the effect of any action upon other
                  constituencies, including employees, suppliers, customers,
                  creditors and the community in which the corporation is
                  located;

         -        A provision that permits shareholders to demand that a
                  controlling person pay to them the fair value of their shares
                  in cash upon a change in control;

         -        A provision that restricts certain business combinations
                  unless there is prior approval by the directors or a
                  supermajority of the shareholders;

         -        A provision permitting a corporation to adopt a shareholders
                  rights plan;

         -        A provision denying the right to vote to a person who acquires
                  a specified percentage of stock ownership unless those voting
                  rights are restored by a vote of disinterested shareholders;
                  and


                                       94
<PAGE>   104
         -        A provision requiring a person who acquires "control share",
                  which are described in the previous sentence, to disgorge to
                  the corporation all profits from the sale of equity securities
                  within eighteen months thereafter.

         Corporations may elect to "opt out" of any or all of these antitakeover
provisions of the Pennsylvania corporate law. Hanover has not elected to opt out
of any of the protections provided by the antitakeover statutes.

INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE

         Certain documents previously filed by Hanover with the Commission are
incorporated by reference into this proxy statement/prospectus as follows:

         -        Hanover's Annual Report on Form 10-K for the year ended
                  December 31, 1999, as filed with the Commission on March 17,

                                   ADJOURNMENT

         In the event that there are not sufficient votes to constitute a quorum
or approve the adoption of the agreement at the time of either of the meetings,
the agreement could not be approved unless the meeting was adjourned in order to
permit further solicitation of proxies. In order to allow proxies that have been
received by either Sterling or Hanover, at the time of each annual meeting to be
voted for the adjournment, if necessary, both Sterling and Hanover have
submitted the question of adjournment under such circumstances to their
shareholders as a separate matter for their consideration. The Boards of
Directors of each of Sterling and Hanover recommend that shareholders vote their
proxies in favor of the respective adjournment proposals. Properly executed
proxies will be voted in favor of the adjournment proposal, unless otherwise
indicated on the proxy. If it is necessary, to adjourn one or both of the
meetings, no notice of the time and place of the adjourned meeting is required
to be given to shareholders other than an announcement of the time and place at
the meeting.

one-third of the directors. The bylaws also provide that the directors of each
class are elected for a term of three years, so that the term of office of one
class of directors expires at the annual meeting each year. The bylaws also
provide that the number of directors in each class of directors is determined by
the Board of Directors.

         A majority of the Board of Directors may increase the number of
directors between meetings of the shareholders. Any vacancy occurring in the
Board of Directors, whether due to an increase in the number of directors,
resignation, retirement, death or any other reason, may be filled by appointment
by the remaining directors. Any director who is appointed to fill a vacancy
holds office until the next annual meeting of the shareholders and until his/her
successor is elected and qualified. There is a mandatory retirement provision in
the bylaws that states that the office of a director is considered vacant at the
annual meeting of shareholders next following his/her attaining the age of 70
years.

         The Board of Directors has fixed the number of directors at 13. There
are five directors whose terms of office will expire at the 2000 annual meeting.
There are eight continuing directors whose terms of office will expire at the
2001 or 2002 annual meeting. The Board of Directors proposes to nominate the
following five persons for election to the Board of Directors for the terms
specified:

                      Nominees for Class of 2003 Directors
                            For a Term of Three Years

                                  S. Amy Argudo
                               Robert H. Caldwell
                                 J. Robert Hess
                               J. Roger Moyer, Jr.
                                W. Garth Sprecher

         Each of the above nominees is presently a director of Sterling
Financial Corporation.

         In the event that any of the nominees are unable to accept nomination
or election, proxyholders will vote proxies given pursuant to this solicitation
in favor of other persons recommended by management. The Board of Directors has
no reason to believe that any of its nominees will be unable to serve as a
director if elected.

         Section 2.3 of Sterling's bylaws requires that nominations, other than
those made by or on behalf of the existing Sterling management, be made pursuant
to timely notice in writing to the Sterling's Secretary. To be timely, a
shareholder's notice must be delivered to or received at the principal executive
office of the corporation not less than 90 days prior to the anniversary date of
the immediately preceding meeting of shareholders of the corporation called for
the election of directors. The chairman of the meeting is required to determine
whether nominations have been made in accordance with the requirements of the
bylaws. If he determines that a nomination was not made in accordance with the
bylaws, he shall so declare at the annual meeting and the defective nomination
will be disregarded.

Board Compensation Committee Report on Executive Compensation

         Role of the Compensation Committee and Compensation Philosophy

         The objectives of the Compensation Committee are to establish the
corporation's compensation philosophy and to monitor compensation programs and
related practices for conformity with that philosophy. The Compensation
Committee believes that the corporation should maintain a competitive
compensation structure with a strong emphasis toward paying for an employee's
contribution and performance. Therefore, the financial interests of the
shareholders are served by closely aligning, particularly for executive
management, year end financial results with an employee's reward for
performance. Accordingly, the committee and the corporation adhere to the
concept of pay-for-performance thus increasing the opportunity to maximize
shareholder value.

         The committee reviews compensation of the corporation's and the bank's
top executives annually. The top executives whose compensation is determined by
the committee include the President and Chief Executive Officer, all Senior
Executive Vice Presidents, all Executive Vice Presidents, all Senior Vice
Presidents and all senior management employees. As a guideline for review in
determining competitive base salaries, the committee uses information from
salary survey sources from Pennsylvania banks with assets from $500 million to
$1 billion, Pennsylvania banks with assets of $1 billion to $4 billion, as well
as peer banks located in the surrounding geographic region. Many local
competitors, represented in these peer groups, share similar performance results
to the Bank of Lancaster County. The committee used these peer group banks
because of common industry issues and competition for the same executive talent.

         The compensation committee is comprised of five non-employee directors
who are listed below. The Committee met seven times during 1999.


                                      110
<PAGE>   120
         Chief Executive Officer Compensation

         The Board of Directors has determined that the Chief Executive
Officer's 1999 compensation of $359,042, comprised of $283,005 in base annual
salary and $76,037 in bonus is appropriate in light of the following 1999
corporation performance accomplishments:

         -        A 7.27% increase in net income;

         -        A 15.17% return on equity; and

         -        A 6.16% increase in assets.

         While there is no direct correlation between the increase in Chief
Executive Officer base salary and these criteria, the Compensation Committee did
review 1998 corporate performance, as well as the peer bank comparisons
mentioned previously, in order to recommend a 6% increase in base salary over
the previous year. The Chief Executive Officer's annual performance incentive
(bonus) is tied directly to the organization's performance results by rewarding
Mr. Stefan for growth in the corporation's net income, return on shareholder
equity and efficiency ratio goals. Mr. Stefan's total bonus of $76,037
represents an increase of 15.5% from the total bonus paid in 1998.

         In addition, Mr. Stefan was awarded an incentive stock option. The
option to purchase 12,500 shares of corporation common stock is listed in the
table listed above. In addition, the Incentive Stock Option program itself is
described elsewhere in this proxy statement.

         Executive Officer Compensation

         Base salary ranges for executive positions are determined by evaluating
the responsibilities of the positions, required skills and experiences and the
average compensation paid for similar positions within peer banks of similar
asset size and within Sterling's geographic market region. The committee
determined annual base salary increases based on its subjective analysis of the
individual's contribution to the corporation's strategic goals and objectives,
and by taking into account any additional or new responsibilities assumed by the
individual in connection with promotions or organizational changes. In
determining whether strategic goals and objectives have been achieved, the Board
of Directors considers among numerous factors the following:

         -        The corporation's performance as measured by earnings;

         -        Revenues;

         -        Return on assets;


                                      111
<PAGE>   121
         -        Return on equity;

         -        Market share;

         -        Total assets; and

         -        Non-performing loans.

         Although the performance and increases in base salary were measured in
light of these factors, there is no direct correlation between any specific
criterion and the employees' base compensation, nor is there any specific weight
provided to any criteria in the committee's analysis. The determination by the
committee is subjective after review of all information it deems relevant.

         The executive officers of Sterling and the bank have an annual
management incentive bonus tied directly to Sterling's performance results.
Similar to the Chief Executive Officer, the executive officers' bonuses are
directly dependent upon the organization's growth in net income, return on
shareholder's equity and Sterling's efficiency ratio. In addition, executive
officers have been awarded incentive stock options to encourage ownership in the
corporation and provide continued focus on enhancing shareholder value.

         In addition to base salary and the management incentive bonus,
executive officers of the corporation and the bank may participate currently in
the following annual and long-term incentive plan:

                         Bank of Lancaster County, N.A.
                              Employees Stock Plan

         Total compensation opportunities available to the employees of the bank
are influenced by general labor market conditions, the specific responsibilities
of the individual and the individual's contributions to Sterling's success.
Individuals are reviewed annually on an anniversary year basis. The bank strives
to offer compensation that is competitive with that offered by employers of
comparable size in the banking industry, as well as those within the
corporation's and the bank's reasonable market area.

1996 Stock Incentive Plan

         Sterling maintains a Stock Incentive Plan that was approved by the
shareholders at the 1997 annual meeting. The purpose of the Stock Incentive Plan
is to advance the development, growth and financial condition of Sterling and
its subsidiaries by providing incentives through participation in the
appreciation of capital stock of the corporation in order to secure, retain and
motivate personnel responsible for the operation and management of Sterling and
its subsidiaries.

         A committee of non-employee directors administers the Stock Incentive
Plan. Persons eligible to receive awards under the Stock Incentive Plan are
those key officers and other management employees of the corporation and its
subsidiaries as determined by the committee.

         There were 82,350 options granted during 1999. There were 100 options
exercised during 1999. At December 31, 1999, there were 435,407 shares reserved
for future grants under the Stock Incentive Plan.

Employees Stock Plan/401(k)

         The Bank of Lancaster County maintains an Employees Stock Plan that was
approved by the shareholders in 1982. All employees of the Bank of Lancaster
County who have attained the age of 18, have completed one year of service and
worked at least 1,000 hours per year are eligible to participate in the plan.
Outside directors are not eligible to participate in the plan. Employees of Town
& Country, Inc., a wholly-owned subsidiary of the Bank of Lancaster County,
participate only in the salary deferral feature of the plan. The plan has two
components:

         -        A salary deferral feature and

         -        A performance incentive feature.

         Under the salary deferral feature of the plan, a participant may make
voluntary contributions to the plan each year of between 2% and 10% of
compensation. The Bank of Lancaster County will make a matching contribution
equal to 25% of each participant's voluntary contributions, up to the first 6%.
Under the performance incentive feature of the plan, the Bank of Lancaster
County contributes to the plan each year an amount determined by the Board of
Directors on the basis of the achievement by the Bank of Lancaster County of
certain performance objectives; contributions to the plan may not exceed the
amount which is deductible under the Internal Revenue Code. Contributions made
by the Bank of Lancaster County to the plan pursuant to the performance
incentive feature are allocated to participants who are employees of Bank of
Lancaster County in the same proportion that each participant's compensation
bears to the aggregate compensation of all participants.

         In 1997, the plan was amended to allow participants to defer their
contributions to five different investment alternatives. Previously, all
contributions to this plan were invested in

                                      113
<PAGE>   123
Sterling common stock. In addition, as of July 1, 1997, participants could elect
to diversify their contributions in increments of 5% to models with the
following investment objectives:

         -        Guaranteed Principal

         -        Fixed Income

         -        Growth and Income

         -        Growth (Equity)

         Sterling's matching contributions and the performance incentive feature
continue to be made in Sterling common stock. In addition, as of January 1,
1998, all participants may elect to diversify their existing holdings in the
pre-tax employee deferral account (those contributions made after January
1,1995) into the four different models. Those participants who are over age 55
and have 10 years of participation in the plan can elect to diversify up to 25%
of their entire post 1987 account balance in accordance with Internal Revenue
Code Section 401(a)(28).

         Voluntary contributions to the plan are fully vested at all times.
Matching contributions and contributions made by the Bank of Lancaster County to
the plan vest at the rate of 20% per year for each year of service. In general
terms, benefits under the plan may be paid to participants upon retirement,
termination of employment, disability or death. A participant may under certain
circumstances make earlier withdrawals (to the extent of his/her interest in the
plan attributable to voluntary contributions made by him/her) upon a showing of
financial hardship.

Pension Plan

         The Bank of Lancaster County Pension Plan is a qualified
non-contributory defined benefit pension plan that provides retirement benefits
to employees of the Bank of Lancaster County, including Messrs. Stefan, Moyer
and Obetz and to employees of Town & Country, Inc., a wholly-owned subsidiary of
the Bank of Lancaster County. All employees who have completed one year of
service, work at least 1,000 hours per year and who have attained the age of 21
are eligible to participate in the plan. Outside directors do not participate in
the plan. Employees become 100% vested upon the completion of five years of
service. Contributions to the plan are made by the Bank of Lancaster County and
are determined actuarially.

         Benefits under the plan, which are not integrated with Social Security
benefits, are based upon average monthly compensation, determined on the basis
of the highest five consecutive years' base compensation preceding retirement
and years of credited service. For purposes of determining benefits payable
under the plan, the term "compensation" is defined to mean base salary only and
does not include overtime pay or bonuses. Compensation paid to Messrs. Stefan,
Moyer and Obetz during 1999 and covered by the plan was $160,000, $152,534 and
$111,198

                                      114
<PAGE>   124
respectively. As of December 31, 1999, Messrs. Stefan, Moyer and Obetz had
accrued 20, 22 and 28 years of credited service, respectively, under the plan
for benefit accrual purposes.

         The following table indicates, for purposes of illustration, the
approximate annual retirement benefit that would be payable under the plan, in
the form of a straight life annuity with 120 months' certain period, at age 65,
under various assumptions as to average annual compensation and years of
credited service. The benefit amounts set forth below are not subject to further
deduction for Social Security or other offset amounts. Under the Internal
Revenue Code, the maximum annual retirement benefit that may be paid in the form
of a straight life annuity with 120 months' certain period under a qualified
defined benefit plan such as the Plan is $120,691, subject to adjustment based
upon increases in the Consumer Price Index. In addition, salary in excess of
$160,000, effective in the year 1997, is disregarded in determining a
participant's retirement benefit pursuant to regulations of the Internal Revenue
Service.

Retirement Restoration Plan

         Bank of Lancaster County adopted a Restoration Plan during 1996 for any
officer whose compensation exceeded $160,000. The plan is designed to "restore"
the level of benefits lost to these employees under certain qualified retirement
plans because of Internal Revenue Code restrictions.

         The plan is designed to mirror the provisions of the qualified
retirement plans available to all Bank of Lancaster County employees--the
Pension Plan, and the Employee Stock or 401(k)

                                      115
<PAGE>   125
plan. The Retirement Restoration Plan allows for the calculation of benefits on
an officer's salary in excess of $160,000. The effective date of the Plan is May
1, 1996.

Employment Agreement

         In July of 1999, Sterling and Bank of Lancaster County entered into a
three year employment agreement and change of control agreement with John E.
Stefan engaging Mr. Stefan as its Chairman, President and Chief Executive
Officer. Unless previously terminated or unless notice of intention not to renew
is given by either party, the employment agreement is subject to automatic
renewal for additional terms of three years each. The employment agreement may
be terminated by Sterling or the Bank of Lancaster County, with or without
cause. If terminated with cause, Mr. Stefan's right to receive salary and
benefits under the employment agreement terminates as of the effective date of
termination. If terminated without cause, the employment agreement with Mr.
Stefan provides for:

         -        A severance payment in the amount of 2.99 times the average
                  annual compensation over the last five years paid in 36 equal
                  monthly installments or a lump sum;

         -        A supplemental payment in lieu of benefits equaling 25% of the
                  payments calculated for compensation or benefits continued
                  throughout the duration of the severance period; and

         -        All stock options granted are immediately 100% vested.

         In the event of any change in control of Sterling or the Bank of
Lancaster County, the same conditions apply, except the severance payments will
be paid in 24 equal monthly installments, or a lump sum. The obligations of the
Bank of Lancaster County under the employment agreement have been jointly and
severally assumed by Sterling.

Change of Control Agreements

         In July of 1999, Sterling and Bank of Lancaster County entered into
three year change of control agreements ending December 31, 2002, with J. Roger
Moyer, Jr., Thomas P. Dautrich and Jere L. Obetz for the purpose of focusing our
executives on the interests of the shareholders should a change in control of
Sterling occur. A "change of control" is defined as:

         -        An acquisition of 20% or more of Sterling's outstanding voting
                  securities;

         -        Execution of an agreement providing for a sale of
                  substantially all of its assets to an entity that is not a
                  direct or indirect subsidiary of Sterling; and

         -        Execution of an agreement providing for a reorganization,
                  merger, consolidation or similar transaction unless the
                  Sterling shareholders will initially own securities
                  representing a majority of the voting power of the resulting
                  corporation and Sterling directors will represent a majority
                  of the directors of the surviving corporation.


                                      116
<PAGE>   126
         Unless previously terminated or unless notice of intention not to renew
is given, the change of control agreement is subject to automatic renewal every
year following the end of the first three year period.


         Agreements with Mr. Moyer and Mr. Dautrich provide for:

         -        A severance payment in the amount of 2.5 times the average
                  annual compensation over the last five years paid either in 30
                  equal monthly installments or a lump sum;

         -        A supplemental payment in lieu of benefits equaling 25% of the
                  payments calculated for compensation or benefits continued
                  throughout the duration of the severance period; and

         -        All stock options granted are immediately 100% vested.

         The agreement with Mr. Obetz provides for:

         -        A severance payment in the amount of 2 times the average
                  annual compensation for the last five years paid either in 24
                  equal monthly installments or a lump sum;

         -        A supplemental payment in lieu of benefits equaling 25% of the
                  payments calculated for compensation or benefits continued
                  throughout the duration of the severance period; and

         -        All stock options granted are immediately 100% vested.

Sterling Financial Corporation Directors' Compensation

         The directors of Sterling do not receive any additional compensation
for their services, beyond the compensation paid to them as directors of the
Bank of Lancaster County. All directors of Sterling are directors of the Bank of
Lancaster County, with the exception of Ms. Argudo who is a director of Sterling
only. Sterling compensates Ms. Argudo as a director. Directors who are also
salaried officers of Sterling or the Bank of Lancaster County do not receive any
fees for board or committee meetings. Each year, the Bank of Lancaster County or
Sterling compensates all its non-employee directors by:

         -        Issuing 200 shares of Sterling common stock to each of them;
                  and

         -        Paying each of them cash equal to the value of the Sterling
                  common stock issued.


                                      117
<PAGE>   127
         The Sterling common stock is issued to directors by July 15th of each
year and is valued at the average closing price for the first ten business days
of July. In addition, each non-employee director receives $100 for each meeting
attended of a Board of Directors committee of which he or she is a member.
Committee chairs receive $150 for each meeting attended. The director's cash
compensation is reduced by one-twelfth for each meeting missed in excess of
three if a director attends fewer than 75% of scheduled Board meetings.

         In July, 1999, each non-employee director received 200 shares of
Sterling common stock, valued at $33.90 per share. The yearly cash portion of
the director's fees was $6,780 for the period beginning July 1, 1999. In the
aggregate, Bank of Lancaster County and Sterling paid $184,570 to non-employee
directors in cash and stock during 1999.

Transactions with Directors and Executive Officers

         Some of the Sterling directors and executive officers and the companies
with which they are associated were customers of and had banking transactions
with the Bank of Lancaster County during 1999. All loans and loan commitments
made to them and to their companies were made in the ordinary course of bank
business, on substantially the same terms, including interest rates, collateral
and repayment terms, as those prevailing at the time for comparable transactions
with other customers of the bank, and did not involve more than a normal risk of
collectibility or present other unfavorable features. The Bank of Lancaster
County anticipates that it will enter into similar transactions in the future.

         The Bank of Lancaster County has entered into several transactions with
businesses that are affiliates of Calvin G. High, a director of Sterling and of
the Bank of Lancaster County. The Bank of Lancaster County entered into a lease
agreement in 1984 with High Properties, in which Mr. High is a partner, under
which High Properties constructed and leased to the Bank of Lancaster County a
building at 525 Greenfield Road, Lancaster, Pennsylvania. Sterling and the Bank
of Lancaster County used the building for their administrative headquarters and
for a branch office from October of 1984 until August 1995. Sterling and the
Bank of Lancaster County moved their administrative headquarters to another
location in August 1995, but the Bank of Lancaster County continued to maintain
a branch office in the Greenfield Road building from October 1984. The term of
the lease for the building was 15 years and was not renewed. The monthly rent
was $12,331.70 and the Bank of Lancaster County paid a total of $49,326.80 in
rent to High Properties during 1999 for the Greenfield Road property.

         On January 10, 1997, the Bank of Lancaster County sublet to High
Employee Services, Ltd., 4,424 square feet of the Greenfield Road building
formerly occupied by Sterling's and the bank's administrative headquarters. High
Employee Services, Ltd. is a division of High Industries, of which Mr. High is a
Director. The term of the sublease was two years eight months and ended on the
expiration date for the original 1984 lease. The Bank of Lancaster County
received $159,264 in rent from High Employee Services for the remaining term of
the sublease.


                                      118
<PAGE>   128
         On October 28, 1998, the Bank of Lancaster County entered into a new
lease agreement with High Properties for its branch bank at the Greenfield Road
building. The lease term commenced on June 1, 1999, the expiration date of the
original lease. Under the terms of the lease, High Properties will lease to the
Bank of Lancaster County 4,424 square feet of space for a term of five years,
subject to renewal. Base rent over the five-year term is $370,999.92.

         The Bank of Lancaster County paid $257,715.69 to D & E Communications
and $398,793.98 to D & E Computer Networking Services, a division of D & E
Communications, Inc. in 1999. The Bank of Lancaster County uses D & E
Communications for telecommunication services. In addition, the Bank of
Lancaster County purchased local area network and wide area network integration
services, personal computer hardware and software and data communications
equipment from D & E Computer Networking Services. W. Garth Sprecher, a Director
of Sterling and the Bank of Lancaster County, is Vice President, Corporate
Secretary and a Director of D & E Communications, Inc.

Section 16(a) Beneficial Ownership Reporting Compliance

         Section 16(a) of the Securities Exchange Act of 1934 requires
Sterling's directors, executive officers and shareholders who beneficially own
more than 10% of Sterling's outstanding equity stock to file initial reports of
ownership and reports of changes in ownership of common stock and other equity
securities of Sterling with the Commission. Based on a review of copies of
reports we received, and on the statements of the reporting persons, Sterling
believes that all Section 16(a) filing requirements were complied with in a
timely fashion during 1999, with the exception of Mr. Calvin G. High who
inadvertently did not timely file two Form 4's reporting changes in ownership
during 1999.

NOMINATIONS AND ELECTION OF DIRECTORS - HANOVER

         Hanover's by-laws provide for the Board of Directors to manage
Hanover's business. Article III, Section 1 of the by-laws provides that the
number of directors not be less than five nor more than 25 and that the members
of the Board hold office for three years and until their successors are duly
elected and qualified. The Board determines the number of directors to be
elected at each annual shareholders meeting to serve during the ensuing year.
The Board may, within the limitations described above, increase the number of
directors by not more than two in any one year, provided that the directors
serve for a term to expire in accordance with the by-laws. Every director is a
shareholder of Hanover and owns, either outright, as tenant by the entirety with
their spouse, or beneficially, 100 shares of Hanover common stock. No person,
except those who were serving as directors as of June 2, 1982, is eligible for
election after he or she obtains the age of 70. Pursuant to Article III, Section
3 of the by-laws, vacancies on the Board may be filled by the remaining members
of the Board, even if less than a quorum, and any director or directors so
elected shall hold office for the unexpired term of the director or directors
who he, she or they replace, and until his, her or their successor or successors
are elected by the shareholders and qualify.


                                      119
<PAGE>   129
         On the date of the annual meeting, the Board will consist of 11
members. Three nominees are to be elected to hold office for a three-year term
and until their successors are duly elected and qualified. The names and certain
information concerning the nominees for election and the other directors whose
terms continue following the annual meeting are shown below. Following the
annual meeting, the Board will consist of 11 members. The proxyholders will vote
"FOR" the nominees listed. If any nominee becomes unavailable for election
(which is not expected), the proxyholders will vote "FOR" other individuals as
the Board may recommend. All business experience shown for each director is for
a period of at least five years.

         Management and the Board recommend the three nominees for election to
the Board and intend to vote their shares "FOR" the nominees.

Compensation of Directors

         Directors of the bank, including the Chairman of the Board, who are not
also employees, are entitled to fees at the rate of $1,500 per quarter, $350 per
regular board meeting and $150 for special board meetings and committee
meetings.

         Terrence L. Hormel, as Chairman of the Board, receives an annual
retainer of $14,400. He receives no fees for committee meetings. Mr. Hormel
earned total fees of $24,600 during 1999. Aggregate fees paid to all directors
in 1999 were $129,400.

         The bank has deferred compensation agreements with five current or
former directors. Under these agreements, participating directors elected to
forego receipt of director's fees for a period of five years in return for a
defined benefit over a ten year period. In order to account for this benefit,
the bank is required to fund a liability which recognizes the bank's future
contractual obligation to the participants. The bank is providing for cost
recovery through the purchase of life insurance policies covering the
participants of which the bank is the owner and beneficiary. Also, the bank has
split dollar agreements with four current directors who had previously
participated in deferred compensation agreements. Under the split dollar
agreements, the bank agrees to purchase a life insurance policy for the
participant until age 65. This life insurance policy is then split to provide
the participant with an undefined amount of compensation over a ten year period
while the bank maintains the policy in force to provide cost recovery. Since
there is no contractual obligation to provide a defined future benefit, the bank
is not required to fund a liability on behalf of the participant. The 1999 costs
associated with the deferred compensation and split dollar agreements were
$38,055.

Compensation Committee Report

         The Board has primary and ultimate responsibility for Hanover's
governance. The Board's fundamental task in discharging this responsibility,
which includes serving as steward for the

                                      125
<PAGE>   135
shareholders' investment and fiduciary for the customers' deposits, is to
provide a capable staff of executive officers, including the Chief Executive
Officer. The Board delegates to these executive officers the necessary authority
to operate and manage Hanover's resources to achieve the Board's stewardship and
fiduciary goals.

         Compensation of executive officers, including the Chief Executive
Officer, is an essential aspect of the Board's governance responsibilities. The
Boards' Executive Committee implements Hanover's Executive Compensation Policy.
This policy provides and maintains a salary and benefit program that rewards
executive officers for service to Hanover at a level sufficient to attract and
retain in each position the appropriate quality individual.

         The compensation range for each position is determined through
evaluation of internal and external equity, labor market conditions, and
specific responsibilities set forth in the position description. Specific
compensation for each executive officer is based primarily on the performance of
the incumbent, as measured in the annual performance review, with the goal of
matching the officer's compensation to his or her "value added" to Hanover. This
"value added" is comprised of two components:

         -        The dollar value of adequately discharging the duties of the
                  office as measured by the pay scale for the position; and

         -        The extra value added by the incumbent's extraordinary effort
                  and results. Thus, the compensation for executive officers
                  consists of base salary plus performance-based incentives.

         Performance-based incentives are determined within the framework of
Hanover's Incentive Compensation Program. The program is based upon the
achievement by corporate employees of targeted annual corporate financial
objectives. Incentive pools exist for all staff and officers as a component of
base salary. A Black Scholes valuation model is utilized for option awards.
Specific awards are determined to recognize the value of individual
contributions during the year.

         In 1999, Hanover awarded both short- and long-term incentives.
Short-term incentives consisted of cash payments. Long-term incentives consisted
of stock option awards. A total of 31,315 options were awarded, of which 6,000
stock options were granted to Mr. Scovill, Hanover's and the bank's Chief
Executive Officer and the Bank. The Board of Directors based this award on the
program parameters and its subjective assessment.

         The Compensation Committee does not deem Section 162(m) of the Internal
Revenue Code to be applicable to Hanover at this time. The committee will
monitor the future application of Section 162(m) to the compensation paid to its
executive officers and in the event that this section becomes applicable, the
committee intends to amend Hanover's compensation plans to preserve the
deductibility of the compensation payable under such plans.

Pension Plan

         On January 19, 1996, the Board of Directors authorized an amendment to
curtail the bank's defined benefit pension plan. Under the curtailment, pension
benefits were frozen and vested as of March 31, 1996. On September 16, 1996,
approximately two thirds of the plan's accumulated benefit obligation was
settled via the purchase of annuity contracts. The retirement plan was
terminated as of July 24, 1998 and all benefit obligations were settled through
the distribution of plan assets by December 31, 1998.

401(k) Plan

         Effective January 1, 1985, the bank made available a 401(k) Plan to
eligible employees. The plan was designed to give employees a source of
financial security and an investment opportunity. The plan is intended to comply
with the requirements of Section 401(k) of the Internal Revenue Code and is
subject to the Employee Retirement Income Security Act of 1974. The plan is
administered by the bank's Investment Services Group which also acts as the
trustee of the plan.

         All employees of Hanover and the bank who have completed at least one
year of employment as defined in the plan and are 21 years of age are eligible
to participate in the plan. In each pay period a participant may elect to defer
up to 15% of base salary/wages and to have that amount contributed to the plan
by the bank on the participant's behalf, up to the maximum allowable
contribution as established by the Internal Revenue Service. In addition,
contributions made on behalf of "highly compensated" employees may be further
restricted as provided for in the Internal Revenue Code. The total amount of a
participant's contributions for a given month is allocated to the plan according
to its terms. Except as may be restricted by the Internal Revenue Code, a
matching contribution is made by the bank equal to 50% of the participant's
contributions for the month, up to 4% of the participant's base salary/wages.
Beginning in 1996, the plan was amended to provide for discretionary
contributions by the bank to all eligible employees. All funds are held in trust
and are invested by the trustee in accordance with the participant's directions
within the scope of investment alternatives available under the plan. All
elective, matching and discretionary contributions are 100% vested upon
placement into the plan.

         Personal after-tax voluntary contributions made prior to January 1,
1988, may be withdrawn at any time upon the required notice. Participants may no
longer make personal after-tax contributions to the plan. Amounts contributed to
the plan on the participant's behalf, as described above, may be withdrawn only
in the event of financial hardship; however, any such withdrawal may not include
any earnings on pre-tax contributions credited to the participant's account
after December 31, 1988. Upon termination of employment or upon attaining the
age of 59 1/2, a participant's entire interest in the plan becomes payable. A
participant may receive a lump sum distribution or may, in certain
circumstances, elect to defer or receive installment payments.

                                      129
<PAGE>   139
         Employer matching contributions and a discretionary contribution made
to all employees of Hanover and the bank during 1999 was $215,532.

Severance Agreement

         On March 22, 1995, Hanover, the bank and J. Bradley Scovill, President
and Chief Executive Officer of Hanover and the bank, entered into a severance
agreement which is triggered upon a change of control of Hanover and the bank.
The agreement provides that if Mr. Scovill is discharged other than for cause,
or Mr. Scovill resigns from the successor to Hanover and/or the bank for good
reason within one year following a change of control of Hanover and/or the bank,
as defined in the agreement, he will receive, monthly, an amount equal to
one-twelfth of his base annual salary that is being paid to him on January 1st
of the year in which the change of control occurs. These monthly payments will
continue for a period of 18 months from the date of his discharge, for reasons
other than for cause, or resignation, for good reason. This 18 month period is
the severance benefit period. In addition, Mr. Scovill will receive, during the
severance benefit period, medical, health, accident and disability insurance and
a survivor's income benefit. These benefits will be equivalent in form,
substance and amount to that provided to him before the commencement of the
severance benefit period.

         Under the terms of the agreement, Mr. Scovill will be required to
mitigate the amount of any payment or benefit provided him as described above by
seeking employment in a substantially similar position, and the successor to
Hanover and the bank will be entitled to setoff against the amount of any
payment or benefit provided to Mr. Scovill, under the terms of the agreement, by
any amounts earned by Mr. Scovill in other employment during the severance
benefit period.

Certain Transactions

         It is not within the policies or practices of Hanover or of Bank of
Hanover to provide personal benefits to principal officers or directors, except
as a measure of reasonable compensation for services. There are no "fringe
benefits" paid or payable to any such person that are not available generally to
all other salaried employees. To facilitate the performance of his duties, the
President and Chief Executive Officer of the bank has been furnished with a
company automobile and a membership to a local country club. This officer pays
all charges attributed to his personal use of these items.

         The corporation and the bank have engaged in, and expect to continue to
engage in, transactions in the ordinary course of business with its directors
and officers and their associates on the same terms, including interest rates
and collateral on loans, as those prevailing at the time for comparable
transactions with others. These transactions do not involve more than the normal
risk of collection, nor do they present other unfavorable features.

         The largest aggregate amount of indebtedness outstanding at any time
during fiscal year 1999 to officers and directors of the corporation and the
bank was $4,656,325. The aggregate amount of

                                      130
<PAGE>   140
indebtedness outstanding as of the latest practicable date, February 29, 2000,
to the above described group was $4,437,332, approximately 13.86% of the total
equity capital of the corporation.

Section 16(a) Beneficial Ownership Reporting Compliance

         Section 16(a) of the Securities Exchange Act of 1934 requires the
corporation's officers and directors, and persons who own more than 10% of the
registered class of the Corporation's equity securities, to file reports of
ownership and changes in ownership with the Securities and Exchange Commission.
Officers, directors, and greater than 10% shareholders are required by SEC
regulation to furnish the Corporation with copies of all filed Section 16(a)
forms.

         Based solely on its review of the copies of such forms received by it,
or on written representation from reporting persons that no Forms 5 were
required for those persons, the Corporation believes that during the period
January 1, 1999, through December 31, 1999, its officers and directors were in
compliance with all Section 16(a) filing requirements applicable to them.

Legal Proceedings

         The nature of the corporation's and the bank's business generates a
certain amount of litigation involving matters arising in the ordinary course of
business. However, in the opinion of management of the corporation and the bank,
there are no proceedings pending to which the corporation and/or the bank are a
party or to which its property is subject which, if determined adversely to the
corporation and the bank, would be material in relation to the corporation's and
the bank's undivided profits or financial condition. No proceedings are pending
other than ordinary routine litigation incidental to the business of the
corporation and the bank. In addition, no material proceedings are pending or
are known to be threatened or contemplated against the corporation and the bank
by government authorities or others.

                     STERLING ANNUAL MEETING - OTHER MATTERS

         In addition to voting on the approval and adoption of the agreement,
the Sterling adjournment proposal and the election of directors, we will ask the
Sterling shareholders to consider and vote upon the following matters:

         -        Ratification of the selection of Ernst & Young, LLP as the
                  corporation's independent certified public accountants for the
                  year ending December 31, 2000; and

         -        Transaction of any other business that may properly come
                  before the Sterling annual meeting.

            RATIFICATION OF SELECTION OF INDEPENDENT CERTIFIED PUBLIC
                                   ACCOUNTANTS

         The Board of Directors engaged Trout, Ebersole & Groff, LLP as
independent certified public accountants to audit Sterling's and the bank's
books, records and accounts for the year 1999. A representative of Trout,
Ebersole & Groff is expected to be present at the 2000 Annual Meeting to respond
to appropriate questions and to make a statement if the representative so
desires.

         The Sterling Board of Directors at its meeting on October 26, 1999,
approved the recommendation of the Audit Committee to retain Ernst & Young LLP
as its independent public accountants for the examination of its financial
statements for the fiscal year ending December 31, 2000. On November 4, 1999,
Sterling agreed to retain Ernst & Young LLP as independent public accountants
for the examination of Sterling's financial statements for the fiscal year
ending December 31, 2000. During the last two most recent fiscal years and
interim periods, there were no disagreements with Trout, Ebersole & Groff, LLP
on matters of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure which disagreement(s) if not resolved
to the satisfaction of Trout, Ebersole & Groff, LLP would have caused them to
make reference to the subject matter of the disagreement(s) in connection with
their report.

         The Board of Directors recommends that the shareholders vote FOR
ratification of the selection of Ernst & Young LLP as independent certified
public accountants for the fiscal year ending December 31, 2000.

         WHEREAS, Sterling is a Pennsylvania corporation and multi-institution
bank holding company; and

         WHEREAS, HBI is a Pennsylvania corporation and bank holding company;
and

         WHEREAS, the boards of directors of Sterling and HBI have each
determined that it is in the best interests of their respective shareholders and

         WHEREAS, Sterling and HBI desire to make certain representations,
warranties, covenants and agreements in connection with this Agreement and to

         WHEREAS, HBI and Sterling desire to merge in the manner provided for
herein and to adopt this Agreement as a plan of merger and to consummate such
plan in accordance with the provisions of Section 368 of the Internal Revenue

                               THE PLAN OF MERGER

SECTION 1.1 The Merger, Closing: Effective Time.

         (a)      Subject to the terms and conditions of this Agreement and in
                  accordance with the applicable laws of the Commonwealth of
                  Pennsylvania, at the Effective Time (as defined in Section 1.
                  1 (c)), HBI shall be merged with and into Sterling and the
                  separate corporate existence of HBI shall thereupon cease.
                  Sterling shall be the surviving corporation in the Merger
                  (sometimes hereinafter referred to as the "Surviving
                  Corporation") and shall continue to be governed by the laws of
                  the Commonwealth of Pennsylvania and shall be a registered
                  bank holding company under the Bank Holding Company Act of
                  1956, as amended, and the separate corporate existence of
                  Sterling with all its rights, privileges, immunities, powers
                  and franchises shall continue unaffected by the Merger. The
                  name of the Surviving Corporation shall be "Sterling Financial
                  Corporation". The Merger shall have the effects specified in
                  the Pennsylvania Business Corporation Law of 1988, as amended
                  (the "PBCL"').

          (b)     The closing of the Merger (the "Closing") shall take place at
                  such place and time and on such date, following three (3)
                  business days' notice to HBI, as shall be agreed upon by all
                  parties, which date shall not be later than the 30th business
                  day after the last of: (i) the last approval of required
                  governmental authorities is granted and any related waiting
                  periods expire, (ii) the lifting, discharge or dismissal of
                  any stay of any such governmental approval or of any
                  injunction against the Merger and (iii) all shareholder
                  approvals required by the parties hereunder are received.

         (c)      Immediately following the Closing, and provided that this
                  Agreement has not been terminated or abandoned pursuant to
                  Article VI hereof, Sterling and HBI will cause articles of
                  merger (the "Articles of Merger") to be delivered and properly
                  filed with the Department of State of the Commonwealth of
                  Pennsylvania (the "Department of State"). The Merger shall
                  become effective on 11:59 p.m. on the day on which the Closing
                  occurs and Articles of Merger are filed with the Department of
                  State or such later date and time as may be agreed upon by the
                  parties and specified in the Articles of Merger (the
                  "Effective Time"). The "Effective Date" when used herein means
                  the day on which the Effective Time for the Merger occurs.

         (d)      At the Effective Time, the articles of incorporation and
                  bylaws of Sterling in effect immediately prior to the
                  Effective Time shall be the articles of incorporation and
                  bylaws of the Surviving Corporation. At the Effective Time,
                  the directors and officers of Sterling immediately prior to
                  the Effective Time shall be and become the directors and
                  officers of the Surviving Corporation with such additions as
                  provided in this Agreement.

                  owned by Sterling or any direct or indirect subsidiary of
                  Sterling, except for trust account shares or shares acquired
                  in connection with debts previously contracted (ii) shares the
                  holders of which (each a "Dissenting Shareholder") are
                  exercising appraisal rights pursuant to the PBCL (the
                  "Dissenters' Shares"), if any), shall, on the Effective Date,
                  be converted into and become, automatically and without any
                  action on the part of the holder thereof, the right to receive
                  shares of common stock, par value, $5.00 per share, of
                  Sterling ("Sterling Common Stock") determined in conformity
                  with the Exchange Ratio set forth at Schedule 2.1 hereof. As
                  of the Effective Time, each share of HBI Common Stock held
                  directly or indirectly by Sterling, other than shares held in
                  a fiduciary capacity or in satisfaction of a debt previously
                  contracted, shall be canceled and retired and cease to exist,
                  and no exchange or payment shall be made with respect thereto.

         (b)      Anti-dilution Provision. In the event that Sterling shall at
                  any time before the Effective Date: (i) declare or pay a
                  dividend in shares of Sterling Common Stock, (ii) combine the
                  outstanding shares of Sterling Common Stock into a smaller
                  number of shares, or (iii) subdivide the outstanding shares of
                  Sterling Common Stock into a greater number of shares, or (iv)
                  reclassify the shares of Sterling Common Stock, then the
                  Exchange Ratio shall be proportionately adjusted accordingly.

         (c)      Assumption of Stock Options. Sterling shall assume the
                  obligations of HBI under the stock options, outstanding as of
                  the date of this Agreement, to purchase 132,657 shares of HBI
                  Common Stock which remain unexercised on the Effective Date
                  (the "HBI Options"). The holder(s) of the HBI Options shall
                  receive stock options (the "Exchange Options") to purchase, on
                  the same terms and conditions as were applicable under the
                  assumed HBI Options, a number of shares of Sterling Common
                  Stock equal to the product of the Exchange Ratio and the
                  number of shares of HBI

                                      A-6
<PAGE>   157

                  Common Stock subject to such HBI Options. The option exercise
                  price per share of the Exchange Options shall be equal to the
                  option exercise price per share of HBI Common Stock divided by
                  the Exchange Ratio (the option price per share, as so
                  determined, being rounded upward to the nearest full cent).
                  The Exchange Options to be received by the HBI Option holders
                  shall be subject to proportional adjustment under Section
                  2.1(b) of this Agreement; provided, however, that the
                  obligation to assume the HBI Options by Sterling is
                  conditioned upon receipt of copies of all executed outstanding
                  options as disclosed on Annex 2.1(c) and receipt of agreements
                  from each of the holders of HBI Options to accept the Exchange
                  Options in exchange therefor. Each Exchange Option shall be
                  exercisable in accordance with the terms of the corresponding
                  HBI Option (including any acceleration of exercisability as a
                  result of the Merger and giving effect to the Exchange Ratio,
                  as provided herein). To the extent an HBI Option qualifies as
                  an incentive stock option under Section 422 of the Code, the
                  corresponding Exchange Option shall also so qualify, to the
                  extent permitted by the PCBL, the federal tax laws and the
                  "pooling of interest"accounting rules. Prior to the Effective
                  Time, Sterling shall reserve for issuance and, if not
                  previously registered pursuant to the Securities Act of 1933,
                  as amended, register the number of shares of Sterling Common
                  Stock necessary to satisfy Sterling's obligations with respect
                  to the issuance of Sterling's Common Stock pursuant to the
                  exercise of the Exchange Options.

         (d)      No Fractional Shares. No fractional shares of Sterling Common
                  Stock, and no scrip or certificates therefor, shall be issued
                  in connection with the Merger. In lieu of the issuance of any
                  fractional share to which he would otherwise be entitled, each
                  former shareholder of HBI shall receive in cash an amount
                  equal to the fair market value of his fractional interest,
                  which fair market value shall be determined by multiplying
                  such fraction by the Closing Market Price (as defined in
                  Schedule 2.1 to this Agreement).

         (e)      HBI Treasury Stock. Each share of HBI Common Stock (other than
                  trust account shares or shares acquired in connection with
                  debts previously contracted) owned by HBI or any direct or
                  indirect subsidiary of HBI on the Effective Date, if any,
                  shall be canceled.

         (f)      HBI Common Stock held by Sterling. Each share of HBI Common
                  Stock (other than trust account shares or shares acquired in
                  connection with debts previously contracted) owned by Sterling
                  or any direct or indirect subsidiary of Sterling on the
                  Effective Date, if any, shall be canceled.

         (g)      Sterling Common Stock.

                  (i)      Each share of Sterling Common Stock issued and
                           outstanding immediately prior to the Effective Date,
                           shall, on and after the Effective Date, continue to
                           be issued and outstanding as an identical share of
                           Sterling Common Stock.

                                       A-7
<PAGE>   158

                  (ii)     Each share of Sterling Common Stock issued and held
                           in the treasury of Sterling as of the Effective Date,
                           if any, shall, on and after the Effective Date,
                           continue to be issued and held in the treasury of
                           Sterling.

SECTION 2.2 Exchange of Stock Certificates.

         HBI Common Stock certificates shall be exchanged for Sterling Common
Stock certificates in accordance with the following procedures:

         (a)      Exchange Agent. The transfer agent of Sterling shall act as
                  exchange agent (the "Exchange Agent") to receive HBI Common
                  Stock certificates from the holders thereof and to exchange
                  such stock certificates for Sterling Common Stock certificates
                  and (if applicable) to pay cash for fractional shares of HBI
                  Common Stock pursuant to Section 2.1(d) above. The Exchange
                  Agent shall, on or promptly after the Effective Date, mail to
                  each former shareholder of HBI a notice specifying the
                  procedures to be followed in surrendering such shareholder's
                  HBI Common Stock certificates.

         (b)      Surrender of Certificates. As promptly as possible after
                  receipt of the Exchange Agent's notice, each former
                  shareholder of HBI shall surrender his HBI Common Stock
                  certificates to the Exchange Agent; provided, that if any
                  former shareholder of HBI shall be unable to surrender his HBI
                  Common Stock certificates due to loss or mutilation thereof,
                  he may make a constructive surrender by following procedures
                  comparable to those customarily used by Sterling for issuing
                  replacement certificates to Sterling shareholders whose
                  Sterling Common Stock certificates have been lost or
                  mutilated. Upon receiving a proper actual or constructive
                  surrender of HBI Common Stock certificates from a former HBI
                  shareholder, the Exchange Agent shall issue to such
                  shareholder, in exchange therefor, a Sterling Common Stock
                  certificate representing the whole number of shares of
                  Sterling Common Stock into which such shareholder's shares of
                  HBI Common Stock have been converted in accordance with this
                  Article II, together with a check in the amount of any cash to
                  which such shareholder is entitled, pursuant to Section 2.1(d)
                  of this Agreement, in lieu of the issuance of a fractional
                  share.

         (c)      Dividend Withholding. Dividends, if any, payable by Sterling
                  after the Effective Date to any former shareholder of HBI who
                  has not prior to the payment date surrendered his HBI Common
                  Stock certificates may, at the option of Sterling, be
                  withheld. Any dividends so withheld shall be paid, without
                  interest, to such former shareholder of HBI upon proper
                  surrender of his HBI Common Stock certificates.

         (d)      Failure to Surrender Certificates. All HBI Common Stock
                  certificates must be surrendered to the Exchange Agent within
                  two (2) years after the Effective Date. In the event that any
                  former shareholder of HBI shall not have properly surrendered
                  his HBI Common Stock certificates within two (2) years after
                  the Effective Date, the

                                      A-8
<PAGE>   159

                  shares of Sterling Common Stock that would otherwise have been
                  issued to him may, at the option of Sterling, be sold and the
                  net proceeds of such sale, together with the cash (if any) to
                  which he is entitled in lieu of the issuance of a fractional
                  share and any previously accrued dividends, shall be held in a
                  non-interest bearing account for his benefit. From and after
                  any such sale, the sole right of such former shareholder of
                  HBI shall be the right to collect such net proceeds, cash and
                  accumulated dividends. Subject to all applicable laws of
                  escheat, such net proceeds, cash and accumulated dividends
                  shall be paid to such former shareholder of HBI, without
                  interest, upon proper surrender of his HBI Common Stock
                  certificates.

         (e)      Expenses of Share Surrender and Exchange. All costs and
                  expenses associated with the foregoing surrender and exchange
                  procedure shall be borne by Sterling. Notwithstanding the
                  foregoing, no party hereto will be liable to any holder of HBI
                  Common Stock for any amount paid in good faith to a public
                  official or agency pursuant to any applicable abandoned
                  property, escheat or similar law.

         (f)      Exchange Procedures. Each certificate for shares of HBI Common
                  Stock delivered for exchange under this Article II must be
                  endorsed in blank by the registered holder thereof or be
                  accompanied by a power of attorney to transfer such shares
                  endorsed in blank by such holder. If more than one certificate
                  is surrendered at one time and in one transmittal package for
                  the same shareholder account, the number of whole shares of
                  Sterling Common Stock for which certificates will be issued
                  pursuant to this Article II will be computed on the basis of
                  the aggregate number of shares represented by the certificates
                  so surrendered. If shares of HBI Common Stock or payments of
                  cash are to be issued or made to a person other than the one
                  in whose name the surrendered certificate is registered, the
                  certificate so surrendered must be properly endorsed in blank,
                  with signature(s) guaranteed, or otherwise in proper form for
                  transfer, and the person to whom certificates for shares of
                  Sterling Common Stock is to be issued or to whom cash is to be
                  paid shall pay any transfer or other taxes required by reason
                  of such issuance or payment to a person other than the
                  registered holder of the certificate for shares of HBI Common
                  Stock which are surrendered. As promptly as practicable after
                  the Effective Date, Sterling shall send, or cause to be sent,
                  to each shareholder of record of HBI Common Stock, transmittal
                  materials for use in exchanging certificates representing HBI
                  Common Stock for certificates representing Sterling Common
                  Stock into which the former have been converted in the Merger.

         (g)      Closing of Stock Transfer Books; Cancellation of HBI
                  Certificates. Upon the Effective Date, the stock transfer
                  books for HBI Common Stock will be closed and no further
                  transfers of shares of HBI Common Stock will thereafter be
                  made or recognized. All certificates for shares of HBI Common
                  Stock surrendered pursuant to this Article II will be canceled
                  by Sterling.

         (h)      Rights Evidenced by Certificate. Each certificate for shares
                  of Sterling Common Stock issued in exchange for certificates
                  of HBI Common Stock pursuant to Section 2.2(f) hereof will be
                  dated as of the Effective Date and be entitled to dividends
                  and all other rights and privileges pertaining to such shares
                  of Sterling Common Stock from the Effective Date. Until
                  surrendered, each certificate theretofore evidencing shares of
                  HBI Common Stock will, from and after the Effective Date,
                  evidence solely the right to receive certificates for shares
                  of Sterling Common Stock pursuant to Section 2.2(f) hereof. If
                  certificates for shares of HBI Common Stock are exchanged for
                  Sterling Common Stock at a date following one or more record
                  dates for the payment of dividends or of any other
                  distribution on the shares of Sterling Common Stock subsequent
                  to the Effective Date, Sterling will pay cash in an amount
                  equal to dividends theretofore payable on such Sterling Common
                  Stock and pay or deliver any other distribution to which
                  holders of shares of Sterling Common Stock have theretofore
                  become entitled. No interest will accrue or be payable in
                  respect of dividends or cash otherwise payable under this
                  Section 2.2 upon surrender of certificates for shares of
                  Sterling Common Stock. Notwithstanding the foregoing, no party
                  hereto will be liable to any holder of HBI Common Stock for
                  any amount paid in good faith to a public official or agency
                  pursuant to any applicable abandoned property, escheat or
                  similar law. Until such time as certificates for shares of HBI
                  Common Stock are surrendered by a HBI shareholder to Sterling
                  for exchange, Sterling shall have the right to withhold
                  dividends or any other distributions, without interest, on the
                  shares of the Sterling Common Stock issuable to such
                  shareholder.

         (i)      Payment Procedures. As soon as practical after the Effective
                  Date, Sterling shall make payment of the cash consideration
                  provided for in Section 2.1(d) to each person entitled
                  thereto.

         (j)      Unclaimed Shares. In the event that any certificates for
                  shares of HBI Common Stock have not been surrendered for
                  exchange in accordance with this Section on or before the
                  second anniversary of the Effective Time, Sterling may at any
                  time thereafter, with or without notice to the holders of
                  record of such certificates, sell for the accounts of any or
                  all of such holders any or all of the shares of Sterling
                  Common Stock which such holders are entitled to receive under
                  Section 2.1(a) hereof (the "Unclaimed Shares"). Any such sale
                  may be made by public or private sale or sale at any broker's
                  board or on any securities exchange in such manner and at such
                  times as Sterling shall determine. If, in the opinion of
                  counsel for Sterling, it is necessary or desirable, any
                  Unclaimed Shares may be registered for sale under the
                  Securities Act of 1933, as amended (the "Securities Act") and
                  applicable state laws. Sterling shall not be obligated to make
                  any sale of Unclaimed Shares if it shall determine not do so,
                  even if notice of sale of the Unclaimed Shares has been given.
                  The net proceeds of any such sale of Unclaimed Shares shall be
                  held for holders of the unsurrendered certificates for shares
                  of HBI Common Stock whose Unclaimed Shares have been sold, to
                  be paid to them upon surrender of the certificates for shares
                  of HBI Common Stock. From and after any such sale, the sole
                  right of the holders

                                      A-10
<PAGE>   161

                  of the unsurrendered certificates for shares of HBI Common
                  Stock whose Unclaimed Shares have been sold shall be the right
                  to collect the net sale proceeds held by Sterling for their
                  respective accounts, and such holders shall not be entitled to
                  receive any interest on such net sale proceeds held by
                  Sterling.

SECTION 2.3 Other Matters.

         Nothing set forth in this Agreement or any Exhibit hereto shall be
construed:

                  (a)      to preclude Sterling from acquiring or assuming, or
                           to limit in any way the right of Sterling to acquire
                           or assume, prior to or following the Effective Time,
                           the stock, assets or liabilities of any other
                           financial services institution or other corporation
                           or entity, whether by issuance or exchange of
                           Sterling Common Stock, or otherwise;

                  (b)      to preclude Sterling from issuing, or to limit in any
                           way the right of Sterling to issue, prior to or
                           following the Effective Date, Sterling Common Stock,
                           Sterling Preferred Stock or other securities;

                           Preferred Stock or other securities;

                  (d)      to preclude option holders of Sterling from
                           exercising options at any time with respect to
                           Sterling Common Stock, Sterling Preferred Stock or
                           other securities; or

                  (e)      to preclude Sterling from taking, or to limit in any
                           way its right to take, any other action not expressly
                           and specifically prohibited by the terms of this
                           Agreement; provided, however, that in the event
                           Sterling desires to (A) take any action described in
                           Section 2.3(a) above, (B) merge or consolidate with

                           agreement relating thereto), and HBI shall have the
                           right, in its sole discretion, to terminate this

                         REPRESENTATIONS AND WARRANTIES

SECTION 3.1 Representations and Warranties of HBI.

         HBI represents and warrants to Sterling (and the word "it" in this
Section 3.1 refers to HBI, and each subsidiary of HBI) that, as of even date
herewith and except as specifically disclosed in the Annex of disclosure
schedules included herewith, as follows:

         (a)      Corporate Organization and Qualification. HBI is a corporation
                  duly incorporated, validly existing and in good standing under
                  the laws of the Commonwealth of Pennsylvania and is in good
                  standing as a foreign corporation in each jurisdiction where
                  the properties owned, leased or operated, or the business
                  conducted, by HBI requires such qualification, except for such
                  failure to qualify or be in such good standing which, when
                  taken together with all other such failures, would not have a
                  Material Adverse Effect on HBI and its subsidiaries, taken as
                  a whole. HBI is a registered bank holding company under the
                  Bank Holding Company Act of 1956, as amended. HBI owns,
                  directly or indirectly all of the issued and outstanding
                  shares of capital stock of Hanover. Hanover is a Pennsylvania
                  chartered bank and trust company, duly organized, validly
                  existing and in good standing under the laws of the
                  Commonwealth of Pennsylvania. HBI and Hanover each have the
                  requisite corporate and other power and authority (including
                  all federal, state, local and foreign governmental
                  authorizations) to carry on their respective businesses as now
                  being conducted and to own its properties and assets. HBI has
                  made available to Sterling a complete and correct copy of the
                  articles of incorporation and bylaws of HBI, and Hanover has
                  made available to Sterling a complete and correct copy of the
                  charter and bylaws of Hanover and such charter or articles, as
                  applicable, and such bylaws are in full force and effect as of
                  the date hereof.

         (b)      Authorized Capital. The authorized capital stock of HBI
                  consists of 9,000,000 shares of HBI Common Stock and 2,000,000
                  shares of preferred stock, of which 3,884,198 shares of HBI
                  Common Stock were issued and outstanding as of the date of
                  this Agreement. The stock of Hanover consists of 600,000
                  shares of common stock, $2.50 par value per share, of which
                  399,574 shares of common stock were issued and outstanding as
                  of the date of this Agreement; all of these are held by HBI.
                  All of the outstanding shares of capital stock of HBI have
                  been duly authorized and are validly issued, fully paid and
                  nonassessable. Neither HBI nor Hanover has any shares of
                  capital stock reserved for issuance except pursuant to the
                  Investment Agreement and the HBI Options. Neither HBI nor
                  Hanover has any outstanding bonds, debentures, notes or other
                  obligations the holders of which have the right to vote (or
                  convertible into or exercisable for securities having the
                  right to vote) with shareholders on any matter. The shares of
                  Hanover's common stock owned by HBI are owned free and clear
                  of all liens, pledges, security interests, claims or other
                  encumbrances. The outstanding shares of capital stock of HBI
                  have not been issued in violation of any

                                      A-12
<PAGE>   163

                  preemptive rights. Except as set forth in Annex 3.1 (b) and in
                  Annex 3.1(m), and as provided in the Investment Agreement,
                  there are no outstanding subscriptions, options, warrants,
                  rights, convertible securities or other agreements or
                  commitments of any character relating to the issued or
                  unissued capital stock or other securities of HBI. After the
                  Effective Time, HBI will have no obligation which is being
                  assumed by Sterling which will result in any obligation to
                  issue, transfer or sell any shares of capital stock pursuant
                  to any HBI/Hanover Employee Plan (as defined in Section 3.1
                  (m)).

         (c)      Subsidiaries. The only subsidiaries of HBI are as listed and
                  described at Annex 3.l(c). The only subsidiaries of Hanover
                  are as listed and described at Annex 3.1(c). Each such
                  subsidiary is duly organized and existing as a corporation, is
                  in good standing under the laws of the jurisdiction in which
                  it was organized, and has adequate corporate power to carry on
                  its business as now conducted. All of the outstanding capital
                  stock of all such subsidiaries has been validly issued, is
                  fully paid and nonassessable and is owned by HBI or Hanover,
                  free and clear of all liens, security interests and
                  encumbrances. Except as set forth in Annex 3.1(c), all such
                  subsidiaries are organized under Pennsylvania law and make no
                  use of fictitious names in the conduct of their respective
                  businesses.

         (d)      Corporate Authority. Subject only to approval of this
                  Agreement by the holders of the number of votes required by
                  HBI's articles of incorporation or bylaws cast by all holders
                  of HBI Common Stock (without any minority, class or series
                  voting requirement), and, subject to the regulatory approvals
                  specified in Section 5.1(b) hereof, HBI has the requisite
                  corporate power and authority, and legal right, and has taken
                  all corporate action necessary in order to execute and deliver
                  this Agreement and to consummate the transactions applicable
                  to either HBI or Hanover contemplated hereby. This Agreement
                  has been duly and validly executed and delivered by HBI and
                  constitutes the valid and binding obligations of HBI
                  enforceable against each, in accordance with its terms, except
                  to the extent enforcement is limited by bankruptcy, insolvency
                  and other similar laws affecting creditors' rights or the
                  application by a court of equitable principles.

         (e)      No Violations. The execution, delivery and performance of this
                  Agreement by it does not, the execution, delivery and
                  performance of the Investment Agreement by it will not, and
                  the consummation of the transactions contemplated hereby by it
                  will not, constitute (i) subject to receipt of the required
                  regulatory approvals specified in Section 5.1(b), a breach or
                  violation of, or a default under, any law, rule or regulation
                  or any judgment, decree, order, governmental permit or
                  license, to which it (or any of its respective properties) is
                  subject, which breach, violation or default would have a
                  Material Adverse Effect on it, or enable any person to enjoin
                  the Merger, (ii) a breach or violation of, or a default under
                  HBI's articles of incorporation, the charter of Hanover, or
                  the bylaws of either of them, or (iii) except as disclosed in
                  Annex 3.1(e), a breach or violation of, or a default under (or
                  an event which with due notice

                  result in the termination of, accelerate the performance
                  required by, or result in the creation of any lien, pledge,
                  security interest, charge or other encumbrance upon any of the
                  properties or assets of it under any of the terms, conditions
                  or provisions of any note, bond, indenture, deed of trust,
                  loan agreement or other agreement, instrument or obligation to
                  which it is a party, or to which any of its respective
                  properties or assets may be bound, or affected, except for any
                  of the foregoing that, individually or in the aggregate, would
                  not have a Material Adverse Effect on it or enable any person
                  to enjoin the Merger; and the consummation of the transactions
                  contemplated hereby or, upon its execution and delivery, the
                  Investment Agreement, will not require any approval, consent
                  or waiver under any such law, rule, regulation, judgment,
                  decree, order, governmental permit or license or the approval,
                  consent or waiver of any other party to any such agreement,
                  indenture or instrument, other than (w) all required
                  approvals, consents and waivers of governmental authorities,
                  (x) the approval of its shareholders referred to in Section
                  5.1(a), (y) any such approval, consent or waiver that already
                  has been obtained, and (z) any other approvals, consents or
                  waivers, the absence of which, individually or in the
                  aggregate, would not result in a Material Adverse Effect on it
                  or enable any person to enjoin the Merger.

         (f)      Reports.

                  (i)      HBI's consolidated statement of financial condition

                  accounting principles) other than those taxes which are being

                  that would have a Material Adverse Effect on it. All taxes,
                  interest, additions and penalties due with respect to
                  completed and settled examinations or concluded litigation

                  has been made for any such taxes on its balance sheet (in
                  accordance with generally accepted accounting principles). It
                  has not executed an extension or waiver of any statute of
                  limitations on the assessment or collection of any tax due
                  that is currently in effect.

                  environmental and occupational safety and health matters, or
                  any other facts or circumstances of which its management is
                  aware that could reasonably be expected to result in any
                  claims against or obligations or liabilities of it), that,
                  alone or in the aggregate, are reasonably likely to have a
                  Material Adverse Effect on it or to hinder or delay, in any

                           transaction" (as defined in Section 406 of ERISA or
                           Section 4975 of the Code) with respect to any
                           HBI/Hanover Employee Plan which is likely to result
                           in any material penalties, taxes or other events
                           under Section 502(i) of ERISA or Section 4975 of the
                           Code which would have a Material Adverse Effect on
                           it.


                  (ii)     No liability to the Pension Benefit Guaranty
                           Corporation has been or is expected by it to be
                           incurred with respect to any HBI/Hanover Employee
                           Plan which is subject to Title IV of ERISA ("Pension
                           Plan"), or with respect to any "single-employer plan"
                           (as defined in Section 4001 (a)(15) of ERISA)
                           currently or formerly maintained by it or any entity
                           which is considered one employer with HBI or Hanover
                           under Section 4001 of ERISA or Section 414 of the
                           Code (an "ERISA Affiliate").

                  (iii)    No Pension Plan or single-employer plan of an ERISA
                           Affiliate had an "accumulated funding deficiency" (as
                           defined in Section 302 of ERISA (whether or not
                           waived)) as of the last day of the end of the most
                           recent plan year ending prior to the date hereof; all
                           contributions to any Pension Plan or single-employer
                           plan of an ERISA Affiliate that were required by
                           Section 302 of ERISA and were due prior to the date

                           dates on which such contributions were due; the fair
                           market value of the assets of each Pension Plan or
                           single-employer plan of an ERISA Affiliate exceeds
                           the present value of the "benefit liabilities" (as
                           defined in Section 4001(a)(16) of ERISA) under such
                           Pension Plan or single employer plan of an ERISA
                           Affiliate as of the end of the most recent plan year
                           with respect to the respective Pension Plan or
                           single-employer plan of an ERISA Affiliate ending
                           prior to the date hereof, calculated on the basis of
                           the actuarial assumptions used in the most recent
                           actuarial valuation for such Pension Plan or
                           single-employer plan of an ERISA Affiliate as of the
                           date hereof; and no notice of a "reportable event"
                           (as defined in Section 4043 of ERISA) for which the
                           30-day reporting requirement has not been waived has
                           been required to be filed for any Pension Plan or
                           single-employer plan of an ERISA Affiliate within the
                           12-month period ending on the date hereof.

                  (iv)     Neither has it provided, nor is it required to
                           provide, security to any Pension Plan or to any
                           single-employer plan of an ERISA Affiliate pursuant
                           to Section 401(a)(29) of the Code.

                  (v)      Neither it nor any ERISA Affiliate has contributed to
                           any "multi-employer plan," as defined in Section
                           3(37) of ERISA, on or after September 26, 1980.

                  (vi)     Each HBI/Hanover Employee Plan of it which is an
                           "employee pension benefit plan" (as defined in
                           Section 3(2) of ERISA) and which is intended to be
                           qualified under Section 401(a) of the Code (a

                           Reduction Act of 1984 and the Tax Reform Act of 1986;
                           it is not aware of any circumstances likely to result
                           in revocation of any such favorable determination
                           letter; each such HBI/Hanover Employee Plan has been
                           amended to reflect the requirements of subsequent
                           legislation applicable to such plans; and each
                           Qualified Plan has complied at all relevant times in
                           all material respects with all applicable
                           requirements of Section 401(a) of the Code.

                  (vii)    Each Qualified Plan which is an "employee stock
                           ownership plan" (as defined in Section 4975(e)(7) of
                           the Code) has at all relevant times satisfied all of
                           the applicable requirements of Sections 409 and
                           4975(e)(7) of the Code and the regulations
                           thereunder.

                  (viii)   Neither it nor any ERISA Affiliate has committed any
                           act or omission or engaged in any transaction that

                  been filed in due and timely fashion. In the judgment of its
                  management, such insurance coverage is adequate.

         (u)      Dividends. The only dividends or other distributions which it
                  has made on its capital stock since January 1, 1999 are set
                  forth in Annex 3.1(u).

         (v)      Books and Records. Its books and records have been, and are
                  being, maintained in accordance with applicable legal and
                  accounting requirements and reflect in all material respects
                  the substance of events and transactions that should be
                  included therein.

         (w)      Board Action. Its board of directors (at a meeting duly called
                  and held) has been duly convened and by the requisite vote of
                  the directors (a) determined that the Merger is advisable and
                  in the best interests of it and its shareholders, (b) approved
                  this Agreement, the Investment Agreement and the transactions
                  contemplated hereby and thereby and (c) directed that the
                  Agreement be submitted for consideration by its shareholders
                  at the HBI Shareholders' Meeting (as hereafter defined) with
                  the recommendation of the board of directors that the
                  shareholders approve the merger and the transactions
                  contemplated thereby.

         (y)      Fairness Opinions. Its board of directors has received a
                  written opinion, a copy of which has been furnished to
                  Sterling, to the effect that the Exchange Ratio specified in
                  this Agreement, at the time of its execution, is fair to HBI
                  shareholders from a financial point of view.

         (y)      Fidelity Bonds. Since at least December 31, 1994, Hanover has
                  continuously maintained fidelity bonds insuring it against
                  acts of dishonesty by its employees in such amounts as is
                  customary for a bank of its size. Since December 31, 1994, the
                  aggregate amount of all potential claims under such bonds has
                  not exceeded $100,000 and neither HBI nor Hanover is aware of
                  any facts which would reasonably form the basis of a claim
                  under such bonds. Neither HBI nor Hanover has reason to
                  believe that its fidelity coverage will not be renewed by its
                  carrier on substantially the same terms as its existing
                  coverage.

         (z)      Condition of Tangible Assets. Except as set forth in Annex
                  3.1(z), all buildings, structures and improvements on the real
                  property owned or leased by it are in good condition, ordinary
                  wear and tear excepted, and are free from structural defects
                  in all material respects. The equipment, including heating,
                  air conditioning and ventilation equipment owned by it, is in
                  good operating condition, ordinary wear and tear excepted. The
                  operation and use of the property in the business conform in
                  all material respects to all applicable laws, ordinances,
                  regulations, permits, licenses and certificates.

         (aa)     Owned Software. To its knowledge, HBI and Hanover do not use
                  any software material to either of their operations that has
                  been designed or developed by HBI"s or Hanover's management
                  information or development staff or by consultants on HBI's or
                  Hanover's behalf.

         (bb)     Licensed Software. The software material to its operations
                  that is used by HBI and Hanover is licensed from third party
                  licensors or constitutes "off-the-shelf" software, is held by
                  HBI or Hanover legitimately and, except as set forth on Annex
                  3.1(bb), is fully transferable hereunder without any third
                  party consent. All of HBI's or Hanover's computer hardware has
                  legitimately licensed software installed therein.

         (cc)     No Errors; Nonconformity. The software material to its
                  operations that is used by HBI or Hanover is free from any
                  material defect or programming or documentation error,
                  operates and runs in a reasonable and efficient business
                  manner and conforms to the stated specifications thereof.

         (dd)     No Bugs or Viruses. Neither HBI nor Hanover has knowingly
                  altered its data, or any software material to its operations
                  which may, in turn, damage the integrity of the data, stored
                  in electronic, optical, or magnetic or other form. Except as
                  set forth on Annex 3.1(dd) hereto, neither HBI nor Hanover has
                  knowledge of the existence of any bugs or viruses with respect
                  to such software.

         (ee)     Annual Reports and Financial Statements. HBI has delivered to
                  Sterling true and complete copies of (i) its Balance Sheets,
                  Statements of Earnings, Statements of Stockholders' Equity and
                  Statements of Cash Flows of HBI for the years ended December
                  31, 1998, 1997 and 1996, certified by independent public
                  accountants, and (ii) HBI's Quarterly Reports for the quarter
                  ended September 30, 1999, containing unaudited consolidated
                  balance sheets of HBI as at such dates and unaudited
                  consolidated statements of earnings and cash flows of HBI for
                  the three month period reflected therein. HBI has also
                  delivered to Sterling true and correct copies of its annual
                  reports to shareholders for the years 1998, 1997 and 1996. All
                  such reports (collectively, the "HBI Reports") (i) comply in
                  all material respects with the requirements of the Financial
                  Accounting Standards Board ("FASB") and the American Institute
                  of Certified Public Accountants, (ii) do not contain any
                  untrue statement of a material fact and (iii) do not omit to
                  state a material fact required to be stated therein or
                  necessary in order to make the statements therein, in light of
                  the circumstances under which they were made, not misleading.
                  No documents to be filed by HBI with the SEC or any regulatory
                  agency in connection with this Agreement, or the transactions
                  contemplated hereby will 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,
                  in light of the circumstances under which they are made, not
                  misleading. All documents which HBI is responsible for filing
                  with the SEC or any regulatory agency in connection with the
                  Merger will comply as to form in all material respects with
                  the requirements of applicable law.

         (ff)     Proxy Statement/Prospectus., Etc. Except for information
                  relating to Sterling and its subsidiaries and pro forma
                  financial information reflecting the combined operations of
                  Sterling and HBI, neither (i) the Proxy Statement/Prospectus
                  (as defined herein at Section 4.3(b)) or any amendment or
                  supplement thereto, at the time it is filed with the SEC, at
                  the time the Registration Statement (as defined hereinafter at
                  Section 4.3(b)) is declared effective, at the time the Proxy
                  Statement/Prospectus is mailed to the shareholders of HBI or
                  at the date of the meeting of the HBI shareholders at which
                  the shareholders will consider this Agreement (the "HBI
                  Shareholders' Meeting") nor (ii) any other documents to be
                  filed by HBI with the SEC or any regulatory agency in
                  connection with this Agreement, or the transactions

                                      A-25
<PAGE>   176

                  contemplated hereby, will contain any untrue statement of
                  material fact or omit to state any material fact required to
                  be stated therein or necessary to make the statements therein,
                  in light of the circumstances under which they are made, not
                  misleading.

         (gg)     Complete and Accurate Disclosure. Neither this Agreement
                  (insofar as it relates to HBI, HBI Common Stock and HBI's
                  involvement in the transactions contemplated hereby) nor any
                  financial statement, schedule (including without limitation
                  the Annexes attached hereto, certificate, or other statement
                  or document delivered by HBI to Sterling in connection
                  herewith contains any statement which, at the time and in
                  light of the circumstances under which it is made, is false or
                  misleading with respect to any material fact or omits to state
                  any material fact necessary to make the statements contained
                  herein or therein not false or misleading. In particular,
                  without limiting the generality of the foregoing sentence, the
                  information provided and the representations made by HBI to
                  Sterling in connection with the Registration Statement, both
                  at the time such information and representations are provided
                  and made and at the time of the Closing, will be true and
                  accurate in all material respects and will not contain any
                  false or misleading statement with respect to any material
                  fact or omit to state any material fact necessary (i) to make
                  the statements made therein not false or misleading, or (ii)
                  to correct any statement contained in an earlier communication
                  with respect to such information or representations which has
                  become false or misleading.

         (hh)     Beneficial Ownership of Sterling Common Stock. Prior to the
                  Effective Date, HBI and its officers and directors will not in
                  the aggregate own beneficially (within the meaning of SEC Rule
                  13d-3(d)(1)) more than five percent (5%) of the outstanding
                  shares of Sterling Common Stock.

         (ii)     Assumability of Contracts and Leases. Except as disclosed on
                  Annex 3.1(ii), all Material Contracts between HBI or Hanover
                  and any other entity or person are assumable and assignable
                  and do not contain any term or provision that would accelerate
                  or increase payments that would otherwise be due by HBI or
                  Hanover to such person or entity, or change or modify the
                  provisions or terms of such leases, contracts and agreements
                  by reason of this Agreement or the transactions contemplated
                  hereby. Except as disclosed on Annex 3.1(ii), each lease
                  pursuant to which HBI or Hanover, as lessee, leases real or
                  personal property is valid and in effect in accordance with
                  its respective terms, and there is not, under any of such
                  leases, on the part of the lessee any material existing
                  default or any event which with notice or lapse of time, or
                  both, would constitute such a default, other than defaults
                  which would not individually or in the aggregate have a
                  material adverse effect on the financial condition, business,
                  prospects, or operating results of HBI.

         (jj)     Absence of Questionable Payments. From and after December 31,
                  1994 neither HBI nor Hanover has, nor, to the knowledge of HBI
                  or Hanover, has any director, officer,

                                      A-26
<PAGE>   177


                  agent, employee, consultant or other person associated with or
                  acting on behalf of, HBI or Hanover (i) used any HBI or
                  Hanover corporate funds for unlawful contributions, gifts,
                  entertainment or unlawful expenses relating to political
                  activity; or (ii) made any direct or indirect unlawful
                  payments to governmental officials from any HBI or Hanover
                  corporate funds, or established or maintained any unlawful or
                  unrecorded accounts with funds received from HBI or Hanover.

         (kk)     Powers of Attorney; Guarantees. Except as set forth on Annex
                  3.1(kk), neither HBI nor Hanover has any power of attorney
                  outstanding, or any obligation or liability either actual,
                  constructive or contingent, as guarantor, surety, cosigner,
                  endorser, co-maker or indemnitor in respect of the obligation
                  of any person, corporation, partnership, joint venture,
                  association, organization or other entity, except for letters
                  of credit issued in the Ordinary Course of Business which are
                  listed on Annex 3.1(ll)

         (ll)     Accuracy of Representations. Until and as of Closing, HBI will
                  promptly notify Sterling if any of the representations
                  contained in this Section 3.1 cease to be true and correct
                  subsequent to the date hereof. Further, no representations
                  made by HBI or Hanover pursuant to this Agreement contain any
                  untrue statement of material fact or omit to state a material
                  fact necessary to make the statements not misleading.

SECTION 3.2  Representations and Warranties of Sterling.

         Sterling represents and warrants to HBI (and the word "it" in this
Section 3.2 refers to Sterling, and each subsidiary of it) that, as of even date
herewith and except as specifically disclosed in the Annex of disclosure
schedules included herewith, as follows:

         (a)      Corporate Organization and Qualification. Sterling is a
                  corporation duly incorporated, validly existing and in good
                  standing under the laws of the Commonwealth of Pennsylvania
                  and is in good standing as a foreign corporation in each
                  jurisdiction where the properties owned, leased or operated,
                  or the business conducted, by Sterling requires such
                  qualification, except for such failure to qualify or be in
                  such good standing which, when taken together with all other
                  such failures, would not have a Material Adverse Effect on
                  Sterling and its subsidiaries, taken as a whole. Sterling is a
                  registered bank holding company under the Bank Holding Company
                  Act of 1956, as amended. Sterling has the requisite corporate
                  and other power and authority (including all federal, state,
                  local and foreign governmental authorizations) to carry on its
                  businesses as now being conducted and to own its properties
                  and assets. Sterling owns, directly or indirectly all of the
                  issued and outstanding shares of capital stock of Bank of
                  Lancaster County, N.A. ("Bank of Lancaster County"), Northeast
                  Bancorp, Inc. and The First National Bank of North East. Bank
                  of Lancaster County and the First National Bank of North East
                  are national banking associations duly organized, validly
                  existing and in good standing under the laws of the United
                  States, and are duly authorized to engage in the banking
                  business as an insured bank under the Federal Deposit
                  Insurance Act, as amended.

<PAGE>   178


                  Bank of Lancaster County is authorized to engage in trust
                  activities. Northeast Bancorp, Inc. is a Delaware corporation
                  and a registered bank holding company under the Bank Holding
                  Company Act of 1956, as amended. Northeast Bancorp, Inc. has
                  the requisite corporate and other power and authority
                  (including all federal, state, local and foreign governmental
                  authorizations) to carry on its businesses as now being
                  conducted and to own its properties and assets. Northeast
                  Bancorp, Inc. directly owns all of the issued and outstanding
                  shares of The First National Bank of North East. Sterling has
                  made available to HBI a complete and correct copy of the
                  articles of incorporation and bylaws of Sterling, and such
                  articles and such bylaws are in full force and effect as of
                  the date hereof.

         (b)      Authorized Capital. The authorized capital stock of Sterling
                  consists of 35,000,000 shares of Sterling Common Stock of
                  which 8,931,568 shares were issued and outstanding as of the
                  date of this Agreement, and 3,220 shares were issued and held
                  as treasury shares as of the date of this Agreement. All of
                  the outstanding shares of capital stock of Sterling have been
                  duly authorized and are validly issued, fully paid and
                  nonassessable. Sterling has no shares of capital stock
                  reserved for issuance. Sterling has no outstanding bonds,
                  debentures, notes or other obligations the holders of which
                  have the right to vote (or convertible into or exercisable for
                  securities having the right to vote) with shareholders on any
                  matter. The outstanding shares of capital stock of Sterling
                  have not been issued in violation of any preemptive rights.
                  Except as set forth in Annex 3.2 (b) and in Annex 3.2(m),
                  there are no outstanding subscriptions, options, warrants,
                  rights, convertible securities or other agreements or
                  commitments of any character relating to the issued or
                  unissued capital stock or other securities of Sterling. After
                  the Effective Time, Sterling will have no obligation which is
                  being assumed by HBI which will result in any obligation to
                  issue, transfer or sell any shares of capital stock pursuant

                  any of its respective properties) is subject, which breach,

                  to which any of its respective properties or assets may be
                  bound, or affected, except for any of the foregoing that,
                  individually or in the aggregate, would not have a Material
                  Adverse Effect on it or enable any person to enjoin the
                  Merger; and the consummation of the transactions contemplated

                  and (z) any other approvals, consents or waivers, the absence
                  of which, individually or in the aggregate, would not result

                  would have a Material Adverse Effect on it. All taxes,
                  interest, additions and penalties due with respect to

                  proceedings before any court, governmental agency or otherwise

                  relating to environmental and occupational safety and health
                  matters, or any other facts or circumstances of which its
                  management is aware that could reasonably be expected to
                  result in any claims against or obligations or liabilities of
                  it), that, alone or in the aggregate, are reasonably likely to
                  have a Material Adverse Effect on it or to hinder or delay, in

                  contemplated by this Agreement.

                  Sterling Regulatory Agency that such body is contemplating
                  issuing or requesting (or is considering the appropriateness
                  of issuing or requesting) any such order, directive, written
                  agreement, memorandum of understanding, extraordinary
                  supervisory letter, commitment letter, board resolution or

                  is subject, other than such defaults or violations as could

                           material respects with all applicable requirements of

                           Sterling Employee Plan which is likely to result in

                           Plan"), or with respect to any "single-employer plan"
                           (as defined in Section 4001 (a)(15) of ERISA)
                           currently or formerly maintained by it or any entity
                           which is considered one employer with Sterling under

                           "ERISA Affiliate").

                           dates on which such contributions were due; the fair

                           amended to reflect the requirements of subsequent
                           legislation applicable to such plans; and each
                           Qualified Plan has complied at all relevant times in

                           the Code) has at all relevant times satisfied all of

                           4975(e)(7) of the Code and the regulations
                           thereunder.

                  (viii)   Neither it nor any ERISA Affiliate has committed any
                           act or omission or engaged in any transaction that
                           has caused it to incur, or created a material risk
                           that it may incur, liability for any excise tax under
                           Sections 4971 through 4980B of the Code, other than
                           excise taxes which heretofore have been paid and

                           applicable law which do not materially increase the
                           cost of such Sterling Employee Plan, and it does not
                           have any obligations for retiree health and life
                           benefits under any Sterling Employee Plan that cannot
                           be terminated without incurring any liability
                           thereunder.

                  (xi)     The execution and delivery of this Agreement and the
                           consummation of the transactions contemplated hereby

                           by Sterling to any person which is an "excess
                           parachute payment" (as defined in Section 280G of the
                           Code) under any Sterling Employee Plan, increase any
                           benefits payable under any Sterling Employee Plan, or

                  consolidated financial statements or notes thereto; (ii) liens
                  on real property for current real estate taxes not yet
                  delinquent, or (iii) such defects in title which would not,
                  individually or in the aggregate, have a Material Adverse
                  Effect on it. With respect to any property leased by it, there
                  are no defaults by it, or to its knowledge, any of the other
                  parties thereto, or any events which, with the giving of
                  notice or lapse of time or both, would become defaults by it
                  or to its knowledge any of the other parties thereto, under
                  any of such leases, except for such defaults or events which
                  would not, individually or in the aggregate, have a Material
                  Adverse Effect on it; and all such leases are in full force
                  and effect and are enforceable against it, as the case may be,
                  and to its knowledge there is no circumstance existing as of
                  the date of this Agreement which causes or would cause such
                  leases to be unenforceable against any of the other parties
                  thereto except as the same may be limited by bankruptcy,
                  insolvency, reorganization, moratorium or similar laws
                  affecting the rights of creditors generally as well as
                  principles of equity to the extent enforcement by a court of
                  equity is required.

                  federal, state, local and foreign governmental or regulatory
                  bodies that are required in order to permit it to carry on its
                  business as it is presently conducted and the absence of which
                  could, individually or in the aggregate, have a Material
                  Adverse Effect on it; all such permits, licenses, certificates
                  of authority, orders and approvals are in full force and
                  effect, and no suspension or cancellation of any of them is

                  neither it nor any of its respective officers, directors,
                  employees or agents have employed any broker or finder or

                  ordinance including, without limitation, the Comprehensive

                  the knowledge of Sterling, there is no reasonable basis for
                  any such proceeding, claim, action or governmental
                  investigation; Sterling is not subject to any agreement,
                  order, judgment, decree or memorandum by or with any court,
                  governmental authority, regulatory agency or third party
                  imposing any such liability.

                  To the knowledge of Sterling, there are and have been no
                  Hazardous Substances or other conditions at any property
                  (whether or not owned operated, or otherwise used by, or the
                  subject of a security interest on behalf of, Sterling or any

                  condition for periods ending after the date of this Agreement
                  will be, in the opinion of management of Sterling and Bank of

                  requirements for all losses reasonably anticipated in the

         (s)      Material Interests of Certain Persons. Except as noted in
                  Annex 3.2(s), none of its respective officers or directors, or
                  any "associate" (as such term is defined in Rule 12b-2 under
                  the Securities Exchange Act of 1934 (the "Exchange Act")) of
                  any such officer or director, has any material interest in any
                  material contract or property (real or personal), tangible or

         (t)      Insurance. All of the insurance policies and bonds maintained
                  by it are in full force and effect, it is not in default
                  thereunder and all material claims thereunder have been filed
                  in due and timely fashion. In the judgment of its management,
                  such insurance coverage is adequate.

         (u)      Dividends. The only dividends or other distributions which it
                  has made on its capital stock since January 1, 1999 are set
                  forth in Annex 3.2(u).

         (v)      Books and Records. Its books and records have been, and are
                  being, maintained in accordance with applicable legal and
                  accounting requirements and reflect in all material respects
                  the substance of events and transactions that should be
                  included therein.

         (w)      Board Action. Its board of directors (at a meeting duly called
                  and held) has been duly convened and by the requisite vote of
                  the directors (a) determined that the Merger is advisable and
                  in the best interests of it and its shareholders, (b) approved
                  this Agreement and the transactions contemplated hereby and
                  thereby and (c)

                                      A-36
<PAGE>   187


                  directed that the Agreement be submitted for consideration by
                  its shareholders at the Sterling Shareholders' Meeting (as
                  hereafter defined) with the recommendation of the board of
                  directors that the shareholders approve the merger and the
                  transactions contemplated thereby.

         (x)      Fairness Opinions. Its board of directors has received a
                  written opinion, a copy of which has been furnished to HBI, to
                  the effect that the Exchange Ratio specified in this
                  Agreement, at the time of its execution, is fair to Sterling's
                  shareholders from a financial point of view.

         (y)      Fidelity Bonds. Since at least December 31, 1992, each
                  Sterling subsidiary has continuously maintained fidelity bonds
                  insuring it against acts of dishonesty by its employees in
                  such amounts as is customary for a bank of its size. Since
                  December 31, 1992, the aggregate amount of all potential
                  claims under such bonds has not exceeded $100,000 and Sterling
                  is not aware of any facts which would reasonably form the
                  basis of a claim under such bonds. Sterling has no reason to
                  believe that its fidelity coverage will not be renewed by its
                  carrier on substantially the same terms as its existing
                  coverage.

         (z)      Condition of Tangible Assets. All buildings, structures and
                  improvements on the real property owned or leased by it are in
                  good condition, ordinary wear and tear excepted, and are free
                  from structural defects in all material respects. The
                  equipment, including heating, air conditioning and ventilation
                  equipment owned by it, is in good operating condition,
                  ordinary wear and tear excepted. The operation and use of the
                  property in the business conform in all material respects to
                  all applicable laws, ordinances, regulations, permits,
                  licenses and certificates.

         (aa)     Annual Reports and Financial Statements. Except as previously
                  disclosed, Sterling has delivered to HBI true and complete
                  copies of (i) its Balance Sheets, Statements of Earnings,
                  Statements of Stockholders' Equity and Statements of Cash
                  Flows of Sterling for the years ended December 31, 1998, 1997

                  statements of earnings and cash flows of Sterling for the
                  three month period reflected therein. Except as previously
                  disclosed, Sterling has also delivered to HBI true and correct
                  copies of its annual reports to shareholders for the years
                  1998, 1997 and 1996. Except as previously disclosed to HBI,
                  all such reports (collectively, the "Sterling Reports") (i)
                  comply in all material respects with the requirements of the
                  Financial Accounting Standards Board ("FASB") and the American
                  Institute of Certified Public Accountants, (ii) do not contain
                  any untrue statement of a material fact and (iii) do not omit

                  respects with the requirements of applicable law.

                  transactions contemplated hereby, will contain any untrue
                  statement of material fact or omit to state any material fact
                  required to be stated therein or necessary to make the

                  they are made, not misleading.

         (cc)     Complete and Accurate Disclosure. Neither this Agreement

         HBI and Sterling shall each use its reasonable best efforts in good
faith, and each of them shall cause its subsidiaries to use their reasonable

without limiting the generality of the foregoing sentence, each shall:

         (a)      cooperate with the other party in the preparation of all
                  required applications for regulatory approval of the

                  preparation of the Registration Statement;

         (b)      call a special or annual meeting of its shareholders and take,
                  in good faith, all actions which are necessary or appropriate
                  on its part in order to secure the approval and adoption of
                  this Agreement by its shareholders at that meeting, including
                  recommending the approval of such agreements by the
                  shareholders. Unless, prior to calling such meeting, the party

         (c)      after receipt of all required regulatory approvals, cooperate
                  with the other party in making employees reasonably available
                  for training prior to the Effective Date, to the extent that
                  such training is deemed reasonably necessary to ensure that

                  subsidiary of Sterling after the Merger;

         (d)      make additions to loan loss reserves and make loan write-offs,

                  rules and directives of the PDB, OCC and FDIC;

                  Agreement;

         (f)      in the case, of HBI, suspend its dividend reinvestment plan,
                  employee stock purchase plan and the option to purchase HBI
                  Common Stock in its 401(k) plan; and

         (g)      modify the Articles of Incorporation or Bylaws or any other
                  documents reasonably requested by the other party necessary to
                  effectuate the transactions contemplated hereby.

SECTION 4.3   Regulatory Matters and Consents

         (a)      Applications for Regulatory Approval. Sterling and HBI shall
                  promptly prepare and file, and use their reasonable best
                  efforts to obtain, all required applications for regulatory
                  approval of the transactions contemplated by this Agreement.
                  Sterling shall provide copies of all applications for
                  regulatory approval to HBI and its counsel for comment and
                  review at least five (5) business days in advance of the
                  anticipated filing date.

         (b)      Registration Statement. Sterling and HBI shall promptly
                  prepare and Sterling shall file with the SEC, a registration
                  statement under the 1933 Act (the "Registration Statement")
                  for the purpose of registering the shares of Sterling Common
                  Stock to be issued under the provisions of this Agreement.
                  Each party may rely upon all information provided to it by the
                  other party in this connection and each party shall not be
                  liable for any untrue statement of a material fact or any
                  omission to state a material fact in the Registration
                  Statement or in the proxy statement and prospectus (the "Proxy
                  Statement/Prospectus") which is prepared as a part thereof, if
                  such statement is made by it in reliance upon any information
                  provided to by the other party or by its agents and
                  representatives. Sterling will advise HBI, after it receives
                  notice thereof, of the time when the Registration Statement or
                  any Pre- or Post-Effective Amendment thereto has become
                  effective or any supplement or amendment has been filed.
                  Sterling shall provide a copy of the Registration Statement to
                  HBI and its counsel for comment and review at least ten (10)
                  business days in advance of the anticipated filing date.

         (c)      State Securities Laws. Sterling, with the cooperation of HBI,
                  shall promptly take all such actions as may be necessary or
                  appropriate in order to comply with all applicable securities
                  laws of any state having jurisdiction over the transactions
                  contemplated by this Agreement. Sterling shall provide a copy
                  of any anticipated application or filing to HBI for comment
                  and review at least five (5) days in advance of the
                  anticipated filing date.

SECTION 4.4 Access to Properties and Records.

         Each party shall give to the other party and their authorized
representatives (including without limitation their counsel, accountants,
economic and environmental consultants and other designated representatives)
reasonable access during normal business hours to all of its properties, books,
contracts, documents and records as the other party may reasonably request,
subject to the obligation, including the obligation of that party's authorized
representatives, to maintain the confidentiality of all non-public information
obtained by reason of such access.

SECTION 4.5  Subsequent Financial Statements.

         Between the date of execution of this Agreement and the Effective Date,
each party shall promptly prepare and deliver to the other party, as soon as
practicable, all internal monthly and quarterly financial statements, reports to
shareholders and reports to regulatory authorities it has prepared, including
all audit reports submitted to it by independent auditors in connection with
each annual, interim or special audit of its books made by such accountants. In
particular, without limiting the generality of the foregoing sentence, HBI shall
deliver to Sterling, and Sterling shall deliver to HBI as soon as practicable a
balance sheet as of December 31, 1999 and a related statement of income for the
three (3) months then ended (which financial statements are hereinafter referred
to as the "December 31, 1999 Financial Statements"). The representations and
warranties set forth in Sections 3.1(f) and 3.2(f) of this Agreement shall apply
to the December 31, 1999 Financial Statements

SECTION 4.6 Board and Committee Minutes.

         HBI shall provide to Sterling, within 10 days after any meeting of the
Board of Directors, or any committee thereof, or any senior or executive
management committee, a copy of the minutes of such meeting.

SECTION 4.7 Update Schedule.

         Each party shall promptly disclose to the other in writing any change,
addition, deletion or other modification to the information set forth in the
Annexes to this Agreement. Notwithstanding the foregoing, disclosures made
subsequent to the date of this Agreement shall not relieve any party from any
and all liabilities for prior statements and disclosures to the other party.

SECTION 4.8  Notice.

         Each party shall promptly notify the other party in writing of any
actions, claims, investigations, proceedings or other developments which, if
pending or in existence on the date of this Agreement, would have been required
to be disclosed to that party in order to ensure the accuracy of the
representations and warranties set forth in this Agreement or which otherwise
could materially and adversely affect the condition (financial or otherwise),
assets, liabilities, business operations or future prospects of the party with
the burden of disclosure.

SECTION 4.9 Other Proposals.

         (a)      HBI shall not solicit or encourage inquiries or proposals with
                  respect to, furnish any information relating to, or
                  participate in any negotiations or discussions concerning any
                  acquisition or purchase of all or a substantial equity
                  interest or portion of the assets in or of HBI or any business
                  combination with HBI other than as contemplated by this
                  Agreement, or authorize or permit any officer, director, agent
                  or affiliate of it to do any of the above, provided, however,
                  that it may respond to an unsolicited,

                                      A-44
<PAGE>   195

                  bona fide, written offer, if the directors of HBI shall have
                  determined in good faith, based of the written opinion of
                  outside counsel (subject to appropriate qualifications) that
                  failure to respond would be reasonably likely to constitute a
                  breach of the HBI board of directors' fiduciary duty under
                  Pennsylvania law; or fail to notify Sterling immediately if
                  any such inquiries or proposals are received by, any such
                  information is requested from, or any such negotiations are
                  sought to be initiated with HBI;

         (b)      HBI shall not authorize or permit any officer, director,
                  employee, agent, consultant, counsel, financial advisor or
                  other representative to, directly or indirectly, solicit,
                  encourage, initiate or engage in discussions or negotiations
                  with, or respond to requests for information, inquiries or
                  other communications from any persons other than Sterling
                  concerning the fact of, or the terms and conditions of, this
                  Agreement, or concerning any acquisition of HBI, or any assets
                  or business thereof (except that HBI officers may respond to
                  inquiries from analysts, regulatory authorities and holders of
                  HBI Common Stock in the Ordinary Course of Business); and HBI
                  shall notify Sterling immediately if any such discussions or
                  negotiations are sought to be initiated with HBI by any such
                  person other than Sterling or if any such requests for
                  information, inquiries, proposals or communications are
                  received from any person other than Sterling. Provided,
                  however, that HBI may respond to an unsolicited bona fide
                  written offer if the directors of HBI shall have determined in
                  good faith, based on the written opinion of outside counsel
                  (subject to appropriate qualifications) that the failure to
                  respond would be reasonably likely to constitute a breach of
                  the HBI board of directors' fiduciary duty under applicable
                  law.

SECTION 4.10  Dividends.

         Between the date of this Agreement and the Effective Date, HBI shall
only declare and pay cash dividends as provided herein. HBI shall only pay
regular quarterly cash dividends in an amount not in excess of $0.12 per share
during each of the first, second and third calendar quarters of 2000. HBI
dividend declaration and payment dates shall be consistent with prior practices
of HBI. Provided, however, that if the Effective Date of the Merger were to
entitle HBI shareholders to a quarterly cash dividend for the respective
calendar quarter from HBI and subsequently from Sterling, then HBI shall not pay
a dividend in said quarter.

SECTION 4.11 Core Deposits.

         HBI shall cause Hanover to use commercially reasonable efforts to
maintain its deposits.

SECTION 4.12 Affiliate Letters.

         HBI shall deliver or cause to be delivered to Sterling, at or before
the Closing (as defined in Section 1.1(c) of this Agreement), a letter or
agreement from its officers, directors and shareholders who may be deemed to be
an "affiliate" (as that term is defined for purposes of Rules 145 and 405
promulgated by the SEC under the 1933 Act) of HBI or Hanover, in form and
substance satisfactory

                                      A-45
<PAGE>   196

to Sterling, under the terms of which each such officer, director or shareholder
acknowledges and agrees to abide by all limitations imposed by the 1933 Act and
by all rules, regulations and releases promulgated thereunder with respect to
the sale or other disposition of the shares of Sterling Common Stock to be
received by such person pursuant to this Agreement.

SECTION 4.13 No Purchases or Sales of Sterling Common Stock During
             Price Determination Period.

         Neither party nor any of its executive officers or directors nor any of
its shareholders who may be deemed to be an "affiliate" (as that term is defined
for purposes of Rules 145 and 405 promulgated by the SEC under the 1933 Act)
shall purchase or sell or submit a bid to purchase or an offer to sell, directly
or indirectly, any shares of Sterling Common Stock or any options, rights or
other securities convertible into shares of Sterling Common Stock during the
Price Determination Period; provided, however, that Sterling may purchase shares
of Sterling Common Stock in the Ordinary Course of Business during the Price
Determination Period pursuant to Sterling's employee benefit plans, stock option
plans or Sterling's dividend reinvestment and stock purchase plan.

SECTION 4.14 Accounting Treatment.

         Each party acknowledges that the other party presently intends to treat
the business combination contemplated by this Agreement as a "pooling of
interests" for financial reporting purposes. Neither party shall take (and shall
use its best efforts not to permit any of its directors, officers, employees,
shareholders, agents, consultants or other representatives to take) any action
which would preclude treating such business combination as a "pooling of
interests" for financial reporting purposes.

SECTION 4.15 Press Releases.

         Neither party shall issue any press release related to this Agreement
or the transactions contemplated hereby or thereby as to which the other party
has not given its prior written consent, which shall not be unreasonably
withheld, and shall consult with the other party as to the form and substance of
other public disclosures related thereto; provided, however, that nothing
contained herein shall prohibit Sterling or HBI from making any disclosure which
its counsel deems reasonably necessary.

SECTION 4.16 Phase I Environmental Audit.

         Each party shall permit the other party, if it elects to do so at its
own expense, a "phase I environmental audit" to be performed at any physical
location owned or occupied on the date hereof by it or any of its subsidiaries.

                           CONDITIONS TO CONSUMMATION

SECTION 5.1 Common Conditions.

         The respective obligations of the parties to effect the Merger shall be
subject to the satisfaction or waiver prior to the Effective Time of the
following conditions:

         (a)      The Agreement and the transactions contemplated hereby and
                  thereby shall have been approved by the requisite vote of the
                  shareholders of HBI and Sterling in accordance with applicable
                  law.

         (b)      All approvals, consents or waivers required by any of the HBI
                  Regulatory Agencies or the Sterling Regulatory Agencies with
                  respect to this Agreement (including the Merger) and the
                  transactions contemplated hereby and thereby including,
                  without limitation, the approvals, notices to, consents or
                  waivers of (i) the Board and (ii) the Pennsylvania Department
                  of Banking (the HBI Regulatory Agencies and the Sterling
                  Regulatory Agencies, are, collectively the "Regulatory
                  Agencies") shall have been obtained and shall remain in full
                  force and effect, and all applicable statutory waiting periods
                  (including without limitation all applicable statutory waiting
                  periods relating to the Merger) shall have expired; and the
                  parties shall have procured all other regulatory approvals,
                  consents or waivers of governmental authorities or other
                  persons that are necessary or appropriate to the consummation
                  of the transactions contemplated by this Agreement, except
                  those approvals, consents or waivers, if any, of which failure
                  to obtain would not, individually or in the aggregate, have a
                  Material Adverse Effect on Sterling, HBI or Hanover (after
                  giving effect to the transaction contemplated hereby);
                  provided, however, that no such approval shall have imposed
                  any condition or requirement which would: (i) require or could
                  reasonably be expected to require (A) any divestiture by
                  Sterling of a portion of the business of Sterling or of any
                  subsidiary or affiliate of Sterling, or (B) any divestiture by
                  HBI or any of its subsidiaries of a portion of its business
                  which Sterling in its good faith judgment believes will have a
                  significant adverse impact on HBI's business or prospects; or
                  (ii) impose any condition upon Sterling or any of its
                  subsidiaries or affiliates, which in Sterling's good faith
                  judgment (x) would be materially burdensome to Sterling and
                  its subsidiaries taken as whole, (y) would significantly
                  increase the costs incurred or that would be incurred by
                  Sterling as a result of consummating the Merger, or (z) would
                  prevent Sterling from obtaining a material benefit
                  contemplated to be attained as a result of the Merger.

         (c)      All other requirements prescribed by law which are necessary
                  to the consummation of the transactions contemplated by this
                  Agreement shall have been satisfied.

         (d)      No party hereto shall be subject to any order, decree or
                  injunction of a court or agency of competent jurisdiction
                  which enjoins or prohibits the consummation of the Merger

                                      A-47
<PAGE>   198

                  or any other transaction contemplated by this Agreement, and
                  no litigation or proceeding shall be pending against any of
                  the parties herein or any of their subsidiaries brought by any
                  governmental agency seeking to prevent consummation of the
                  transactions contemplated hereby.

         (e)      No statute, rule, regulation, order, injunction or decree
                  shall have been enacted, entered, promulgated or enforced by
                  any governmental authority which prohibits, restricts or makes
                  illegal consummation of the Merger or any other transaction
                  contemplated by this Agreement.

         (f)      The Registration Statement shall have been filed (the date of
                  which is referred to herein as the "Filing Date") by Sterling
                  with the SEC under the 1933 Act, and shall have been declared
                  effective prior to the time the Proxy Statement/ Prospectus is
                  first mailed to the respective shareholders of Sterling and
                  HBI, and no stop order with respect to the effectiveness of
                  the Registration Statement shall have been issued; the
                  Sterling Common Stock to be issued pursuant to this Agreement
                  shall be duly registered or qualified under the securities or
                  "blue sky" laws of all states in which such action is required
                  for purposes of the initial issuance of such shares and the
                  distribution thereof to the shareholders of HBI entitled to
                  receive such shares.

         (g)      An opinion of Shumaker Williams, P.C., or from Ernst & Young,
                  LLP, shall have been received by Sterling and HBI to the
                  effect that:

                  (i)      The Merger will constitute a reorganization within
                           the meaning of Section 368(a) of the Code and HBI and
                           Sterling will each be a "party to a reorganization"
                           within the meaning of Section 368(b) of the Code;

                  (ii)     No gain or loss will be recognized by HBI or Sterling
                           by reason of the Merger;

                  (iii)    Except for cash received in lieu of fractional shares
                           and cash received by HBI Shareholders who exercise
                           their dissenter's rights, no gain or loss will be
                           recognized by the shareholders of HBI who receive
                           solely Sterling Common Stock upon the exchange of
                           their shares of HBI Common Stock for shares of
                           Sterling Common Stock;

                  (iv)     The tax basis of the Sterling Common Stock to be
                           received by the HBI shareholders will be, in each
                           instance, the same as the basis of the HBI Common
                           Stock surrendered in exchange therefor;

                  (v)      The holding period of the Sterling Common Stock
                           received by a HBI shareholder receiving Sterling
                           Common Stock will include the period during which the
                           HBI Common Stock surrendered in exchange therefor was
                           held;


                                      A-48
<PAGE>   199

                  (vi)     Cash received by a HBI shareholder in lieu of a
                           fractional share interest of Sterling Common Stock or
                           upon exercise of dissenter's rights will be treated
                           as having been received as a distribution in full
                           payment in exchange for the fractional share interest
                           of Sterling Common Stock, or the tax basis in the
                           shares surrendered, as the case may be, which he
                           would otherwise be entitled to receive and will
                           qualify as capital gain or loss; and

                  (vii)    Subject to any limitations imposed under Sections 381
                           and 382 of the Code, Sterling, as the survivor to the
                           Merger, will carry-over and take into account all
                           accounting items and tax attributes of HBI, including
                           but not limited to earning and profits, methods of
                           accounting, and tax basis and holding periods of HBI.

         In case a ruling from the IRS is sought, HBI and Sterling shall
         cooperate and each shall furnish to the other and to the IRS such
         information and representations as shall, in the opinion of counsel for

                  this Agreement shall be true and correct in all material
                  respects as of the Effective Date as if made on such date (or
                  on the date when made in the case of any representation or
                  warranty which specifically relates to an earlier date); HBI
                  shall have performed each of its covenants and agreements
                  contained in this Agreement; and Sterling shall have received
                  certificates signed by the President or Vice President and the

         (b)      Ernst & Young, LLP, or such other accounting firm as is
                  acceptable to the parties, shall have furnished to Sterling an
                  "agreed upon procedures" letter, dated the Effective Date, in
                  form and substance satisfactory to Sterling to the effect
                  that, based upon a procedure performed with respect to the
                  financial condition of HBI, Hanover and affiliates, for the
                  period from December 31, 1999 to a specified date not more

                  responsible for financial and accounting matters as to

                  liabilities, and (c) of other specified procedures and
                  inquiries performed by them, nothing has come to their
                  attention that would indicate that (A) during the period from

                  days prior to the date of such letter, there was any change in

                                      A-49
<PAGE>   200

                  capitalization of HBI or Hanover on a consolidated basis, or
                  (B) any material adjustments would be required to the audited
                  financial statements for the period ended December 31, 1999 in
                  order for them to be in conformity with generally accepted

                  condition, properties, assets, business or results of

                  aggregate, has had or might reasonably be expected to result
                  in a Material Adverse Effect on HBI or Hanover.

         (e)      The Merger shall as of the date of the Closing meet the
                  requirements for pooling-of-interests accounting treatment

                  accounting rules of the SEC, and Sterling shall have received
                  a letter from Ernst & Young, LLP in form and substance
                  reasonably satisfactory to Sterling as to the matters
                  specified in Section 5.2(e).

                  Closing, all issued and outstanding options, warrants or
                  rights to acquire HBI Common Stock or any capital stock of

                  in the Merger in respect of any such rights which remain
                  unexercised at the Effective Time.

                  Sterling Common Stock shall have exercised their statutory
                  appraisal or Dissenters' Rights.

         (i)      No environmental problem of the kind contemplated in Section
                  3.1(q) of Article III of this Agreement and not previously
                  disclosed on Annex 3.1(q) shall have been discovered which
                  would, or which potentially could, materially and adversely
                  affect the condition (financial or otherwise), assets,
                  liabilities, business, operations or future prospects of HBI
                  or Hanover; provided, that for purposes of determining the
                  materiality of an undisclosed environmental problem or
                  problems, the definition of "material" shall be governed by
                  the proviso to Section 8.1 of this Agreement. The result of
                  any "phase I environmental audit" conducted pursuant to
                  Section 4.16 with

                  McPherson & Associates, Inc. as of a date no later than the
                  date of the Proxy Statement/Prospectus mailed to the Sterling
                  shareholders in connection with the Merger to the effect that
                  the Exchange Ratio is fair to Sterling's shareholders from a
                  financial point of view.

         (k)      All litigation pending against HBI or Hanover which,
                  individually or in the aggregate, would have a Material
                  Adverse Effect on HBI's consolidated operations, business or
                  future prospects, shall have been settled or otherwise
                  resolved on terms satisfactory to Sterling.

                  provided, however, that such date may be extended by the

SECTION 7.1   Employees and Benefits.

         (a)      Except as otherwise provided in this Agreement, Sterling and
                  Hanover shall use their best efforts (but shall be under no
                  obligation) to employ, as officers and employees of Hanover
                  immediately following the Effective Date, any persons who are
                  officers and employees of Hanover immediately before the
                  Effective Date (the "Continuing Employees"), provided that
                  such employment shall be on an "at will" basis. It shall be a

                  benefits related to severance arrangements upon a change of
                  control or otherwise, prior to accepting such new employment
                  and without accepting any of the severance benefits or other

                  or understanding.

         (b)      After the Effective Date, all benefits of each of the
                  Continuing Employees will be maintained at a level at least
                  equal to the benefits enjoyed by the employee of Hanover prior
                  to the Effective Date, with such changes to compensation and
                  benefits in the future as may be appropriate, as determined by
                  Sterling's and Hanover's Board of Directors.

         (c)      After the Effective Date, Continuing Employees shall be
                  eligible to apply for any positions available at Sterling, or

         (d)      As provided herein, Sterling will permit, after the Merger,
                  severance payments to employees of HBI and Hanover (other than
                  employees whose severance benefits are provided for in written
                  employment agreements) whose employment is terminated (other
                  than for cause) on or after the Effective Date, and before the
                  expiration of six (6) months following the Effective Date and
                  who sign a release of any and all claims the employee may have
                  against HBI, Hanover, Sterling or a Sterling affiliate.
                  Sterling, HBI and Hanover shall consult and mutually agree
                  upon the individual amounts to be received by former HBI or
                  Hanover employees who are eligible for severance payments.

SECTION 7.2   Officers.

         Hanover's senior executive officers who are employed in good standing
and actively at work as of the Effective Date (the "Continuing Officers") shall
be employed and retained in their current management positions with compensation
initially at least equal to their current levels of compensation, with such
changes to employment status, compensation and benefits in the future as

                                      A-54
<PAGE>   205

may be appropriate, as determined by Sterling's and Hanover's Board of

terminate any of the Continuing Officers at any time following the Effective
Date for "Good Reason", as that term shall be reasonably defined by Sterling.

                  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
                  actions or omissions occurring at or prior to the Effective
                  Date (and also advance expenses incurred to the fullest extent
                  permitted by applicable law), with the exception of (i)
                  actions or omissions occurring in connection with the
                  transactions contemplated by this Agreement and the Investment
                  Agreement, whether asserted or claimed prior to, at or after
                  the Effective Date, and (ii) liability for fraud, deception or
                  intentional misrepresentation.; provided, however, that
                  Sterling shall not have an obligation hereunder to any
                  Indemnified Party when and if a court of competent
                  jurisdiction shall ultimately determine, and such
                  determination shall become final and non-appealable, that the
                  indemnification of such Indemnified Party in the manner
                  contemplated hereby is prohibited by applicable law.

         (b)      For a period of six (6) years following the Effective Date,
                  Sterling shall pay the premiums for a Director and Officer
                  Liability Insurance Tail Policy for the Directors and Officers
                  of HBI as of the Effective Date and for all former directors
                  and officers of HBI, if so permitted by the insurance carrier
                  and within the financial limitations of this Section 7.5(b),
                  with conditions and terms substantially comparable to the
                  Director and Officer Liability Policy of HBI as of the date of
                  this Agreement, so long as such policy can be obtained at a
                  cost not in excess of 150% of the rate for such Director and
                  Officer Liability Insurance Tail Policy in effect as of the
                  date of this Agreement. In the event Sterling is unable to
                  obtain such a Director and Officer Liability Insurance Tail
                  Policy at a cost not in excess of 150% of such rate, Sterling
                  shall obtain a Director and Officer Liability Insurance Tail

                  cost that is equal to 150% of such rate.

                  corporate name "Bank of Hanover and Trust Company", and until
                  such time as the Sterling and Hanover Board of Directors
                  determine otherwise. Sterling shall use its best efforts to
                  maintain the level of customer service and community support
                  as has been the custom of HBI.

                  waive any of all of the provisions of Sections 7.3 or 7.6.

SECTION 8.11   Change of Control Fee.

         (a)      In the event that a Change of Control of HBI is effected, or
                  HBI or Hanover enters into an agreement to effect a Change of
                  Control, within sixty (60) days of the termination of this
                  Agreement in accordance with the terms hereof (and provided
                  that such period shall be extended to November 30, 2000, if
                  such termination results from a breach by HBI of its
                  obligations hereunder), and so long as Sterling shall not have
                  breached its obligations hereunder, then HBI shall promptly,
                  but in no event later than two (2) business days after the
                  Change of Control or entering into an agreement to effect a

                  fails to promptly pay the amount due pursuant to this Section
                  8.11 and, in order to obtain such payment, Sterling commences
                  a suit which results in a judgment against HBI for all or a
                  substantial portion of the fee set forth in this Section 8.11,
                  HBI shall pay to Sterling all costs and expenses (including
                  reasonable attorneys' fees) incurred by Sterling in connection
                  with such suit. This Section 8.11 shall survive any
                  termination of this Agreement.

         (b)      As used in this Section 8.11 and subsection (d) of Schedule
                  2.1 and Section 2.3(e) of this Agreement, "Change of Control"
                  shall mean the occurrence of any of the following:

<PAGE>   210

                  transfer or other disposition of substantially all of the
                  assets of HBI, Hanover or Sterling, as the case may be, or (C)
                  a purchase by HBI or Hanover of substantially all of the
                  assets of another entity, unless (y) the shareholders of HBI
                  or Sterling, as the case may be, are to hold shares of the
                  legal entity resulting from or existing after the transaction
                  to be outstanding immediately after such transaction entitled
                  to cast at least a majority of the votes entitled to be cast
                  generally for the election of directors; or

         (ii)     any other change of control of HBI, Hanover or Sterling, as
                  the case may be, similar in effect to any of the foregoing.

         SECTION 8.12 Notices.

         All notices, requests, acknowledgments and other communications
hereunder to a party shall be in writing and shall be deemed to have been duly

                                  SCHEDULE 2.1


                               Exchange Provisions


         (a) Each of the outstanding shares of HBI Common Stock shall be
exchanged for 0.93 shares of Sterling Common Stock and the Exchange Ratio shall
be 0.93. Subject to the provisions of Section 2.1(b), the aggregate number of
shares of Sterling Common Stock to be issued under this Agreement shall not
exceed 3,735,675 shares (assuming the exercise of all of the HBI Options prior
to the Effective Date).

         (b) The Closing Market Price of Sterling Common Stock shall be the
arithmetic average of the per share mean of the closing bid price and the
closing asked price for Sterling Common Stock for each of the twenty (20)
trading days immediately preceding the date which is five (5) business days
before the Effective Date, as reported on the National Market System of the
National Association of Securities Dealers Automated Quotation System
(NASDAQ/NMS), the foregoing twenty (20) trading days being hereinafter sometimes
referred to as the "Price Determination Period". (For example, if June 30, 2000

22.) In the event that NASDAQ/NMS shall fail to report a closing bid price and
closing asked price, respectively, for Sterling Common Stock for any trading day
during the Price Determination Period, then the per share mean price for that
day shall be equal to the average of the closing bid prices and the closing
asked prices as quoted: (i) by two market makers in Sterling Common Stock listed
in Sterling's 1999 Third Quarter Report to Shareholders; or (ii) in the event
that neither of these firms is then making a market in Sterling Common Stock, by
two brokerage firms then making a market in Sterling Common Stock to be selected
by Sterling and approved by the Board of Directors of HBI which approval shall
not be unreasonably withheld.

                              INVESTMENT AGREEMENT


         THIS AGREEMENT dated as of January 25, 2000, between STERLING FINANCIAL
CORPORATION ("STERLING") and HANOVER BANCORP, INC. ("HANOVER BANCORP"),

                                   WITNESSETH:

         WHEREAS, Sterling and Hanover Bancorp have, simultaneously with
executing this Agreement, entered into an Agreement and Plan of Merger dated as
of the date hereof (the "Plan"); and

         WHEREAS, as a condition to Sterling's entry into the Plan and in
consideration of such entry, Hanover Bancorp has agreed to issue to Sterling, on
the terms and conditions set forth herein, options entitling Sterling to
purchase up to an aggregate of 772,955 shares (the "Shares") of Hanover
Bancorp's common stock, par value $0.83 per share ("Hanover Bancorp Common
Stock");

         NOW, THEREFORE, in consideration of the execution of the Plan and the
agreements herein contained, Sterling and Hanover Bancorp, intending to be
legally bound hereby, agree as follows:

         1. Concurrently with the execution of the Plan and this Agreement,
Hanover Bancorp shall issue to Sterling an option or options in the form of
Attachment A hereto (the "Option", which term as used herein shall include any
options issued upon transfer or exchange of the original Option or pursuant to
Paragraph 4 of this Agreement) to purchase up to 772,955 shares of Hanover
Bancorp Common Stock. Each Option shall be exercisable at a price per share of
$14.00, subject to adjustment as therein provided (the "Exercise Price"). So
long as the Option is outstanding and unexercised, Hanover Bancorp shall at all
times maintain and reserve, free from preemptive rights, such number of
authorized but unissued or treasury shares of Hanover Bancorp Common Stock as
may be necessary so that the Option may be exercised without additional
authorization of Hanover Bancorp Common Stock after giving effect to all other
options, warrants, convertible securities and other rights to acquire shares of
Hanover Bancorp Common Stock at the time outstanding. Hanover Bancorp represents
and warrants that it has duly authorized the issuance of the Shares upon
exercise of the Option and covenants that the Shares issued upon exercise of the
Option shall be duly authorized, validly issued and fully paid and nonassessable
and subject to no preemptive rights. The Option and the Shares are hereinafter
collectively referred to, from time to time, as the "Securities".

         So long as the Option is owned by Sterling, in no event shall Sterling
exercise the Option for a number of shares of Hanover Bancorp Common Stock
which, when added to the number of shares of Hanover Bancorp Common Stock owned
or controlled by Sterling (otherwise than in a fiduciary capacity) would result
in Sterling owning or controlling (otherwise than in a fiduciary

                                      A-65
<PAGE>   216
capacity) more than 19.9 percent of the shares of Hanover Bancorp Common Stock
issued and outstanding immediately after giving effect to such exercise.

         2. Subject to the terms and conditions hereof, Sterling may exercise or
sell the Option, in whole or in part, upon: (i) the failure of Hanover Bancorp's
shareholders to approve the Plan at a meeting called for such purpose after the
announcement by a qualified and financially capable person (other than Sterling)
of a bona fide written offer to acquire 20 percent or more of Hanover Bancorp
Common Stock, or to acquire, merge or consolidate with Hanover Bancorp or to
purchase or acquire all or substantially all of Hanover Bancorp's assets; (ii)
the acquisition by any person (other than Sterling) of beneficial ownership of
20 percent or more of Hanover Bancorp Common Stock exclusive of shares of
Hanover Bancorp Common Stock sold directly or indirectly to such person by
Sterling; (iii) any person (other than Sterling) shall have commenced a tender
or exchange offer, or shall have filed an application with an appropriate bank
regulatory authority with respect to a publicly announced offer, to purchase or
acquire securities of Hanover Bancorp such that, upon consummation of such
offer, such person would own, control or have the right to acquire 20 percent or
more of Hanover Bancorp Common Stock (before giving effect to any exercise of
the Option); or (iv) Hanover Bancorp shall have entered into an agreement with a
person (other than Sterling) for such person to acquire, merge or consolidate
with Hanover Bancorp or to purchase or acquire all or substantially all of
Hanover Bancorp's assets. Sterling's right to exercise the Option shall
terminate and be of no further effect, except as to notices of exercise given
prior thereto, upon termination of the Option as provided in Paragraph 10
thereof. As used in this Paragraph 2, "person" and "beneficial ownership" shall
have the same meanings as in the Option. Notwithstanding the foregoing, Hanover
Bancorp shall not be obligated to issue Shares upon exercise of the Option (i)
in the absence of any required governmental or regulatory approval or consent
necessary for Hanover Bancorp to issue the Shares or for Sterling to exercise
the Option or prior to the expiration or termination of any waiting period
required by law or (ii) so long as any injunction or other order, decree or
ruling issued by any federal or state court of competent jurisdiction is in
effect which prohibits the sale or delivery of the Shares. Any sale of the
Option, in whole or in part, or any of the Shares by Sterling, other than a sale
to a majority-owned subsidiary of Sterling, shall be subject to the right of
first refusal of Hanover Bancorp (or any assignee or assignees of Hanover
Bancorp the identity of whom or which prior to the date thereof has been given
to Sterling) at a price equal to the written offer price which Sterling receives
from a third party (other than a majority-owned subsidiary of Sterling) and
intends to accept. The right of first refusal shall terminate 20 days after
notice of Sterling's intention to sell has been delivered to Hanover Bancorp. If
an offer is made for a consideration which in whole or in part consists of other
than cash, the value of the non-cash portion of the consideration shall be
determined by a recognized investment banking firm selected jointly by Sterling
and Hanover Bancorp, and such determination shall in no event be made later than
the fifth day after notice of Sterling's intention to sell has been delivered to
Hanover Bancorp. In the event of the failure or refusal of Hanover Bancorp to
purchase the Option or all the Shares covered by Sterling's notice to sell,
Sterling may, within 30 days from the date of such notice, unless additional
time is needed to give notification to or to obtain approval from any
governmental or regulatory authority and, if so required, within five days after
the date on which the required notification period has expired or been
terminated or such approval has been obtained and any requisite waiting period
with respect

                                      A-66
<PAGE>   217
thereto has passed, sell all, but not less than all, of the portion of the
Option or such Shares covered by such notice to such proposed transferee at no
less than the price specified and on terms no more favorable to the buyer than
those set forth in the notice.

         3. Subject to applicable regulatory restrictions, from and after the
date on which any event described in the second paragraph of this Paragraph 3
occurs, the Holder as defined in the Option (which shall include a former
Holder) who has exercised the Option in whole or in part shall have the right to
require Hanover Bancorp to redeem some or all of the Shares at a redemption
price per share (the "Redemption Price") equal to the highest of: (i) one
hundred and fifteen percent (115 %) of the Exercise Price in the case of an
event under subsection (i) of the second paragraph of this Paragraph 3 occurs or
one hundred twenty-five percent (125%) of the Exercise Price in the case of an
event under subsection (ii) of the second paragraph of this Paragraph 3 occurs;
(ii) the highest price paid or agreed to be paid for any share of Hanover
Bancorp Common Stock by an Acquiring Person (as defined in the Option) during
the twelve months immediately preceding the date notice of the election to
require redemption is given by the Holder under the third paragraph of this
Paragraph 3 (as appropriately adjusted to reflect any of the events described in
Paragraph 7(A) of the Option); and (iii) in the event of a sale of all or
substantially all of Hanover Bancorp's assets, (x) the sum of the price paid in
such sale for such assets and the current market value of the remaining assets
of Hanover Bancorp as determined by a recognized investment banking firm
selected by such Holder, divided by (y) the number of shares of Hanover Bancorp
Common Stock then outstanding. If the price paid consists in whole or in part of
the securities or assets other than cash, the value of such securities or assets
shall be their then current market value as determined by a recognized
investment banking firm selected by the Holder. The Holder's right to require
Hanover Bancorp to redeem some or all of the Shares under this Paragraph 3 shall
expire on the close of business on the 180th day following the occurrence of any
event described in the second paragraph of this Paragraph 3.

         The redemption rights provided in this Paragraph 3 shall become
exercisable upon the occurrence of any of the following events: (i) the
acquisition by any person (other than Sterling or any subsidiary of Sterling) of
beneficial ownership of 20 percent or more of the Hanover Bancorp Common Stock
(before giving effect to any exercise of the Option) exclusive of shares of
Hanover Bancorp Common Stock sold directly or indirectly to such person by
Sterling or (ii) a transaction of the type specified in Paragraph 2(iv)shall
have been consummated. As used in this Paragraph 3 "person" and "beneficial
ownership" shall have the same meanings as in the Option.

         The Holder may exercise its right to require Hanover Bancorp to redeem
some or all of the Shares pursuant to this Paragraph 3 by surrendering for such
purpose to Hanover Bancorp, at its principal office within the time period
specified in the preceding paragraph, a certificate or certificates representing
the number of Shares to be redeemed accompanied by a written notice stating that
it elects to require Hanover Bancorp to redeem all or a specified number of such
Shares in accordance with the provisions of this Paragraph 3. As promptly as
practicable, and in any event within ten business days after the surrender of
such certificates and the receipt of such notice relating thereto, Hanover
Bancorp shall deliver or cause to be delivered to the Holder the Redemption
Price multiplied by the number of Shares that the Holder is requiring Hanover

                                      A-67
<PAGE>   218
Bancorp to redeem which it is not then prohibited under applicable law or
regulation from redeeming, and, if the Holder has given Hanover Bancorp notice
that less than the full number of Shares evidenced by the surrendered
certificate or certificates are to be redeemed, a new certificate or
certificates, of like tenor, for the number of Shares evidenced by such
surrendered certificate or certificates, less the number of Shares redeemed. To
the extent that Hanover Bancorp is prohibited under applicable law or
regulation, or by judicial or administrative action, from redeeming all of the
Shares as to which the Holder has given notice to redeem hereunder, Hanover
Bancorp shall immediately notify the Holder and thereafter deliver or cause to
be delivered to the Holder the applicable Redemption Price for such number of
the Shares as it is not prohibited from redeeming within ten business days after
the date on which Hanover Bancorp is no longer so prohibited; provided, however,
that at the option of Sterling, at any time after receipt of such notice from
Hanover Bancorp, Hanover Bancorp shall deliver to the Holder a certificate for
such number of the Shares as it is then prohibited from redeeming, or, at the
Holder's option, all the Shares, and Hanover Bancorp shall have no further
obligation to redeem such Shares.

         4. In the event that Hanover Bancorp issues any additional Shares of
Hanover Bancorp Common Stock pursuant to outstanding stock options after the
date of this Agreement, Hanover Bancorp shall issue additional options to
Sterling, such that, after such issuance, the number of Shares of Hanover
Bancorp Common Stock subject to all options hereunder, together with any shares
of Hanover Bancorp Common Stock previously issued pursuant hereto, equals 19.9
percent of the shares of Hanover Bancorp Common Stock then issued and
outstanding. Such additional options shall be identical to the Option.

         5. Hanover Bancorp will not enter into any transaction described in
(a), (b) or (c) of Paragraph 6(A) of the Option unless the Acquiror (as defined
in the Option) assumes in writing, in form and substance satisfactory to the
Holder, all the obligations of Hanover Bancorp hereunder.

         6. This Agreement shall not be assignable by Sterling except to any
direct or indirect subsidiary, affiliate or successor of Sterling.

         7. Without limiting the foregoing or any remedies available to
Sterling, it is specifically acknowledged that Sterling would not have an
adequate remedy at law for any breach of this Agreement and will be entitled to
specific performance of the obligations under, and injunctive relief against
actual or threatened violations of the obligations of any person subject to this
Agreement.

                                     OPTION

                       TO PURCHASE UP TO 772,955 SHARES OF
                                  COMMON STOCK

                              HANOVER BANCORP, INC.


         This is to certify that, for value received, STERLING FINANCIAL
CORPORATION ("Sterling") or any permitted transferee (Sterling or such
transferee hereinafter the "Holder") is entitled to purchase, subject to the
provisions of this Option and of the Agreement (as hereinafter defined), from
HANOVER BANCORP, INC. ("Hanover Bancorp"), at any time on or after the date
hereof, an aggregate of up to 772,955 fully paid and nonassessable shares of
common stock, par value $0.83 per share ("Hanover Bancorp Common Stock") of
Hanover Bancorp at a price per share equal to $14.00, subject to adjustment as
herein provided (the "Exercise Price").

         1.       Exercise of Option. Subject to the provisions hereof and the
                  limitations set forth in Paragraph 2 of an Investment
                  Agreement dated as of January 25, 2000, by and between
                  Sterling and Hanover Bancorp (the "Agreement") executed and
                  delivered in connection with an Agreement and Plan of Merger
                  dated as of January 25, 2000, between Sterling and Hanover
                  Bancorp (the "Plan"), this Option may be exercised at any time
                  or from time to time on or after the date hereof. This Option
                  shall be exercised by presentation and surrender hereof to
                  Hanover Bancorp at its principal office, accompanied by (i) a
                  written notice of exercise, (ii) payment to Hanover Bancorp,
                  for the account of Hanover Bancorp, of the Exercise Price for
                  the number of shares of Hanover Bancorp Common Stock specified
                  in such notice and (iii) a certificate of the Holder
                  specifying the event or events which have occurred which
                  entitle the Holder to exercise the Option. The Exercise Price
                  for the number of shares of Hanover Bancorp Common Stock
                  specified in the notice shall be payable in immediately
                  available funds. This Option may not be exercised in part for
                  less than 10,000 shares, except (i) for an initial exercise
                  resulting in ownership of approximately 5 percent of the
                  outstanding shares of Hanover Bancorp Common Stock after
                  giving effect to the exercise, (ii) as limited by applicable
                  law, regulation or regulatory order or (iii) when this Option
                  becomes exercisable for less than 10,000 shares, the remaining
                  shares for which it is then exercisable.

         Upon such presentation and surrender, Hanover Bancorp shall issue
promptly (and within five business days if requested by the Holder) to the
Holder or its assignee, transferee or designee the shares of Hanover Bancorp
Common Stock to which the Holder is entitled hereunder.

         If this Option should be exercised in part only, Hanover Bancorp shall,
upon surrender of this Option for cancellation, execute and deliver a new Option
evidencing the rights of the Holder thereof to purchase the balance of the
shares of Hanover Bancorp Common Stock purchasable

                                      A-70
<PAGE>   221
hereunder. Upon receipt by Hanover Bancorp of this Option, in proper form for
exercise, the Holder shall be deemed to be the holder of record of the shares of
Hanover Bancorp Common Stock issuable upon such exercise, notwithstanding that
the stock transfer books of Hanover Bancorp may then be closed or that
certificates representing such shares of Hanover Bancorp Common Stock shall not
then be actually delivered to the Holder. Hanover Bancorp 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 pursuant to this Paragraph 1 in the name of the
Holder or its assignee, transferee or designee.

         2.       Reservation of Shares; Preservation of Rights of Holder.
                  Hanover Bancorp shall at all times while this Option is
                  outstanding and unexercised maintain and reserve, free from
                  preemptive rights, such number of authorized but unissued or
                  treasury shares of Hanover Bancorp Common Stock as may be
                  necessary so that this Option may be exercised without
                  additional authorization of Hanover Bancorp Common Stock after
                  giving effect to all other options, warrants, convertible
                  securities and other rights to acquire shares of Hanover
                  Bancorp Common Stock at the time outstanding. Hanover Bancorp
                  further agrees (i) 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 or under the Agreement by Hanover Bancorp,
                  (ii) that it will use its best efforts to take all action
                  (including (A) complying with all premerger notification,
                  reporting and waiting period requirements specified in 15
                  U.S.C. Section 18a and the regulations promulgated thereunder
                  and (B) in the event that under the Bank Holding Company Act
                  of 1956 or the Change in Bank Control Act or any other law,
                  prior approval of the Board of Governors of the Federal
                  Reserve System (the "Board"), the Securities Regulatory
                  Commissions (SEC), or any other regulatory agency is necessary
                  before this Option may be exercised, cooperating fully with
                  the Holder in preparing any and all such applications and
                  providing such information to the Board as such agency may
                  require) in order to permit the Holder to exercise this Option
                  and Hanover Bancorp duly and effectively to issue shares of
                  Hanover Bancorp Common Stock hereunder, and (iii) that it will
                  promptly take all action necessary to protect the rights of
                  the Holder against dilution as provided herein.

         3.       Fractional Shares. Hanover Bancorp shall not be required to
                  issue fractional shares of Hanover Bancorp Common Stock upon
                  exercise of this Option but shall pay for such fraction of a
                  share in cash or by certified or official bank check at the
                  Exercise Price.

         4.       Exchange, Transfer or Loss of Option. This Option is
                  exchangeable or, subject to Paragraph 2 of the Investment
                  Agreement, transferable, without expense, at the option of the
                  Holder, upon presentation and surrender hereof at the
                  principal office of Hanover Bancorp for other Options of
                  different denominations entitling the Holder to purchase in
                  the aggregate the same number of shares of Hanover Bancorp
                  Common Stock purchasable hereunder. The term "Option" as used
                  herein includes

                  any Options for which this Option may be exchanged. Upon
                  receipt by Hanover Bancorp of evidence reasonably satisfactory
                  to it of the loss, theft, destruction or mutilation of this
                  Option, and (in the case of loss, theft or destruction) of
                  reasonably satisfactory indemnification, and upon surrender
                  and cancellation of this Option, if mutilated, Hanover Bancorp
                  will execute and deliver a new Option of like tenor and date.

         This Option may not be exercised or sold except in accordance with the
terms of the Agreement.

         5. Redemption.

                  (A) Subject to applicable regulatory restrictions, from and
         after the date on which any event described in the second paragraph of
         Paragraph 3 of the Agreement occurs, the Holder shall have the right to
         require Hanover Bancorp to redeem this Option at a redemption price
         (the "Redemption Amount") equal to (x) the highest of: (i) the number
         of shares of Hanover Bancorp Common Stock for which this Option is then
         exercisable (the "Conversion Number") multiplied by the Exercise Price
         multiplied by 115% in the case of an event under subsection (i) of the
         second paragraph of Paragraph 3 of the Agreement occurs or 125% in the
         case of an event under subsection (ii) of the second paragraph of
         Paragraph 3 of the Agreement occurs; (ii) the highest price paid or
         agreed to be paid for any share of Hanover Bancorp Common Stock by the
         Acquiring Person (as hereinafter defined) during the twelve months
         immediately preceding the date notice of the election to require
         redemption is given by the Holder under Paragraph 5(B)(such price to be
         appropriately adjusted to reflect the effect of any of the events
         described in Paragraph 7(A) hereof), multiplied by the Conversion
         Number; and (iii) in the event of the sale of all or substantially all
         of the assets of Hanover Bancorp, the Conversion Number multiplied by
         (I) the sum of (a) the price paid for such assets and (b) the current
         market value of the remaining assets of Hanover Bancorp, as determined
         by a recognized investment banking firm selected by the Holder, divided
         by (II) the sum of the number of shares of Hanover Bancorp Common Stock
         then outstanding, less (y) the Exercise Price multiplied by the
         Conversion Number. If, for the purpose of this calculation or
         calculating the Assigned Value (as hereinafter described), the price
         paid consists in whole or in part of securities or assets other than
         cash, the value of such securities or assets shall be their then
         current market value as determined by a recognized investment banking
         firm selected by the Holder. The Holder's right to require Hanover
         Bancorp to redeem this Option under this Paragraph 5 shall expire at
         the close of business on the 180th day following the occurrence of any
         event described in the second paragraph of Paragraph 3 of the
         Agreement.

                  (B) The Holder of this Option may exercise its right to
         require Hanover Bancorp to redeem this Option pursuant to this
         Paragraph 5 by surrendering for such purpose to Hanover Bancorp, at its
         principal office, within the period specified above, this Option
         accompanied by a written notice stating that the Holder elects to
         require Hanover Bancorp to redeem this Option in accordance with the
         provisions of this Paragraph 5. As promptly as practicable, and in any
         event within ten business days after the surrender of this Option

                                      A-72
<PAGE>   223
         and the receipt of such notice relating thereto, Hanover Bancorp shall
         deliver or cause to be delivered to the Holder the Redemption Amount
         therefor or the portion thereof which it is not then prohibited under
         applicable law and regulation from delivering to the Holder.


                  To the extent that Hanover Bancorp is prohibited under
         applicable law or regulation, or as a result of administrative or
         judicial action, from redeeming this Option in full, Hanover Bancorp
         shall immediately notify the Holder and thereafter deliver or cause to
         be delivered to the Holder the portion of the Redemption Amount which
         it is no longer prohibited from delivering to the Holder within ten
         business days after the date on which Hanover Bancorp is no longer so
         prohibited; provided, however, that, at the option of the Holder, at
         any time after receipt of such notice, Hanover Bancorp shall deliver to
         the Holder a new Option evidencing the right to the Holder to purchase
         that number of shares of Hanover Bancorp Common Stock obtained by
         multiplying the Conversion Number in effect at such time by a fraction,
         the numerator of which is the Redemption Amount less the portion
         thereof (if any) theretofore delivered to the Holder and the
         denominator of which is the Redemption Amount, and Hanover Bancorp
         shall have no further obligation to redeem such new Option.

                  (C) As used in this Option, the following terms have the
meanings indicated:

                           (a) "Acquiring Person" shall mean any "Person"
                  (hereinafter defined) who or which shall be the "Beneficial
                  Owner" (as hereinafter defined) of 20% or more of Hanover
                  Bancorp Common Stock;

                           (b) A "Person" shall mean any individual, firm,
                  corporation or other entity and include as well any syndicate
                  or group deemed to be a "person" by Section 13(d)(3) of the
                  Securities Exchange Act of 1934, as amended;

                           (c) A Person shall be a "Beneficial Owner" of all
                  securities:

                                    (i) which such Person or any of its
                           "Affiliates" (as hereinafter defined) or "Associates"
                           (as hereinafter defined) beneficially owns, directly
                           or indirectly; and

                                    (ii) which such Person or any of its
                           Affiliates or Associates has (1) the right to acquire
                           (whether such right is exercisable immediately or
                           only after the passage of time or otherwise) pursuant
                           to any agreement, arrangement or understanding or
                           upon the exercise of conversion rights, exchange
                           rights, warrants or options, or otherwise, or (2) the
                           right to vote pursuant to any agreement, arrangement
                           or understanding; and

                           (d) "Affiliate" and "Associate" shall have the
                  respective meanings ascribed to such terms in Rule 12b-2 of
                  the General Rules and Regulations

                                      A-73
<PAGE>   224
                  promulgated under the Securities Exchange Act of 1934, as
                  amended, as in effect on the date of the Agreement.

         6. Certain Transactions.

                  (A) In case Hanover Bancorp (a) shall consolidate with or
         merge into any Person, other than the Holder or one of its Affiliates,
         and shall not be the continuing or surviving corporation of such
         consolidation or merger, (b) shall permit any Person, other than the
         Holder or one of its Affiliates, to merge into Hanover Bancorp and
         Hanover Bancorp shall be the continuing or surviving corporation, but,
         in connection with such merger, the then outstanding shares of Hanover
         Bancorp Common Stock shall be changed into or exchanged for stock or
         other securities of any other Person or cash or any other property or
         shall represent less than 25% of the shares of Hanover Bancorp Common
         Stock immediately after giving effect to the merger, or (c) shall sell
         or otherwise transfer all or substantially all of its assets to any
         Person, other than the Holder or one of its Affiliates, then, and in
         each such case, the agreement governing such transaction shall make
         proper provision so that this Option shall (at the option of the
         Holder, in whole or in part), upon the consummation of any such
         transaction and upon the terms and conditions set forth herein, be
         converted into, or exchanged for, a option, at the option of the
         Holder, of either (I) the Acquiring Corporation (as hereinafter
         defined), (II) any company which controls the Acquiring Corporation, or
         (III) in the case of a merger described in clause (A)(b), Hanover
         Bancorp, in which case such option shall be a newly issued option (in
         any such case, the "Substitute Option").

                  (B) The following terms have the meanings indicated:

                           (a) "Acquiring Corporation" shall mean (i) the
                  continuing or surviving corporation of a consolidation or
                  merger with Hanover Bancorp (if other than the Hanover
                  Bancorp), (ii) the corporation merging into Hanover Bancorp in
                  a merger in which the Hanover Bancorp is the continuing or
                  surviving person and in connection with which the then
                  outstanding shares of Hanover Bancorp Common Stock are changed
                  into or exchanged for stock of other securities of any other
                  Person or cash or any other property or shall represent less
                  than 50% of the shares of Hanover Bancorp Common Stock
                  immediately after giving effect to the merger, and (iii) the
                  transferee of all or substantially all of Hanover Bancorp's
                  assets, Hanover Bancorp or all or substantially all of the
                  Hanover Bancorp's assets;

                           (b) "Substitute Common Stock" shall mean the common
                  stock issued by the issuer of the Substitute Option;

                           (c) "Assigned Value" shall mean the Redemption Price
                  per share of Hanover Bancorp Common Stock (as defined in
                  Paragraph 3 of the Agreement) multiplied by the Conversion
                  Number;

                                      A-74
<PAGE>   225
                           (d) "Average Price" shall mean the average closing
                  price (or if unavailable, the average of the daily averages of
                  the closing bid and asked prices) of a share of Substitute
                  Common Stock for the one year immediately preceding the
                  consolidation, merger or sale in question, but in no event
                  higher than the closing price (or average of the closing bid
                  and asked prices) of a share of Substitute Common Stock on the
                  day preceding such consolidation, merger or sale; provided
                  that if Hanover Bancorp is the issuer of the Substitute
                  Option, the Average Price shall be computed with respect to a
                  share of the common stock issued by the Person merging into
                  Hanover Bancorp or by any company which controls such Person,
                  as the Holder may elect. If the Average Price cannot be
                  computed as aforesaid because neither closing prices nor
                  closing bid and asked prices are available for such one-year
                  period, then the Average Price shall be the average fair
                  market value of a share of Substitute Common Stock for such
                  period (but in no event higher than the fair market value on
                  the day preceding such consolidation, merger or sale) as
                  determined by a recognized investment banking firm selected by
                  Sterling.

                  (C) The Substitute Option shall have the same terms as this
         Option provided that if the terms of the Substitute Option cannot, for
         legal reasons, be the same as this 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 of the Substitute Option in substantially the same
         form as the Agreement, which shall be applicable to the Substitute
         Option. For purposes of the Substitute Option and such agreement, any
         event referred to in Paragraph 2 or Paragraph 3 of the Agreement shall
         be deemed to have occurred when it occurred with respect to Hanover
         Bancorp.

                  (D) The Substitute Option shall be immediately exercisable for
         such number of shares of Substitute Common Stock as is equal to the
         Assigned Value divided by the Average Price. The exercise price of the
         Substitute Option per share of Substitute Common Stock shall be equal
         to the Exercise Price multiplied by a fraction in which the numerator
         is the Conversion Number and the denominator is 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
         aggregate of the outstanding shares of Substitute Common Stock and the
         shares of Substitute Common Stock issuable upon exercise of the
         Substitute Option.

         7.       Adjustment. The number of shares of Hanover Bancorp Common
                  Stock purchasable upon the exercise of this Option and the
                  Exercise Price shall be subject to adjustment from time to
                  time as provided in this Paragraph 7:

                           (A)(1) In case Hanover Bancorp shall pay or make a
                  dividend or other distribution on any class of capital stock
                  of Hanover Bancorp in Hanover Bancorp Common Stock, the number
                  of shares of Hanover Bancorp Common Stock purchasable upon
                  exercise of this Option shall be increased by multiplying such

                                      A-75
<PAGE>   226
                  number of shares by a fraction of which the denominator shall
                  be the number of shares of Hanover Bancorp Common Stock
                  outstanding at the close of business on the day immediately
                  preceding the date of such distribution and the numerator
                  shall be the sum of such number of shares and the total number
                  of shares constituting such dividend or other distribution,
                  such increase to become effective immediately after the
                  opening of business on the day following such distribution,
                  provided, however, that in no event shall the Option be
                  exercised for more than 19.9% of the shares of Hanover Bancorp
                  Common Stock issued and outstanding.

                           (2) In case outstanding shares of Hanover Bancorp
                  Common Stock shall be subdivided into a greater number of
                  shares of Hanover Bancorp Common Stock, the number of shares
                  of Hanover Bancorp Common Stock purchasable upon exercise of
                  this Option at the opening of business on the day following
                  the day upon which such subdivision becomes effective shall be
                  proportionately increased, and, conversely, in case
                  outstanding shares of Hanover Bancorp Common Stock shall each
                  be combined into a smaller number of shares of Hanover Bancorp
                  Common Stock, the number of shares of Hanover Bancorp Common
                  Stock purchasable upon exercise of this Option at the opening
                  of business on the day following the day upon which such
                  combination becomes effective shall be proportionately
                  decreased, such increase or decrease, as the case may be, to
                  become effective immediately after the opening of business on
                  the day following the day upon which such subdivision or
                  combination becomes effective, provided, however, that in no
                  event shall the Option be exercised for more than 19.9% of the
                  shares of Hanover Bancorp Common Stock issued and outstanding.

                           (3) The reclassification (excluding any transaction
                  in which a Substitute Option would be issued) of Hanover
                  Bancorp Common Stock into securities (other than Hanover
                  Bancorp Common Stock) and/or cash and/or other consideration
                  shall be deemed to involve a subdivision or combination, as
                  the case may be, of the number of shares of Hanover Bancorp
                  Common Stock outstanding immediately prior to such
                  reclassification into the number or amount of securities
                  and/or cash and/or other consideration outstanding immediately
                  thereafter and the effective date of such reclassification
                  shall be deemed to be "the day upon which such subdivision
                  becomes effective," or "the day upon which such combination
                  becomes effective," as the case may be, within the meaning of
                  clause (2) above.

                           (4) Hanover Bancorp may make such increases in the
                  number of shares of Hanover Bancorp Common Stock purchasable
                  upon exercise of this Option, in addition to those required by
                  this subparagraph (A), as shall be determined by its Board of
                  Directors to be advisable in order to avoid taxation so far as
                  practicable of any dividend of stock or stock rights or any
                  event treated as such for federal income tax purposes to the
                  recipients.

                  (B) Whenever the number of shares of Hanover Bancorp Common
         Stock purchasable upon exercise of this Option is adjusted as herein
         provided, the Exercise Price

                                      A-76
<PAGE>   227
         shall be adjusted by a fraction in which the numerator is equal to the
         number of shares of Hanover Bancorp Common Stock purchasable prior to
         the adjustment and the denominator is equal to the number of shares of
         Hanover Bancorp Common Stock purchasable after the adjustment.

                  (C) For the purpose of this Paragraph 7, the term "Hanover
         Bancorp Common Stock" shall include any shares of Hanover Bancorp of
         any class or series which has no preference or priority in the payment
         of dividends or in the distribution of assets upon any voluntary or
         involuntary liquidation, dissolution or winding up of Hanover Bancorp
         and which is not subject to redemption by Hanover Bancorp.

         8.       Notice.

                  (A) Whenever the number of shares for which this Option is
         exercisable is adjusted as provided in Paragraph 7, Hanover Bancorp
         shall promptly compute such adjustment and mail to the Holder a
         certificate, signed by a principal financial officer of Hanover
         Bancorp, setting forth the number of shares of Hanover Bancorp Common
         Stock for which this Option is exercisable as a result of such
         adjustment, a brief statement of the facts requiring such adjustment
         and the computation thereof and when such adjustment will become
         effective.

                  (B) Upon the occurrence of any event which results in this
         Option becoming redeemable, as provided in Paragraph 5, Hanover Bancorp
         shall promptly notify the Holder of such event; and promptly compute
         the Redemption Amount and furnish to the Holder a certificate, signed
         by a principal financial officer of Hanover Bancorp, setting forth the
         Redemption Amount and the basis and computation thereof.

                  (C) Upon the occurrence of an event which results in this
         Option becoming convertible into, or exchangeable for, the Substitute
         Option, as provided in Paragraph 6, the Acquiring Corporation and
         Hanover Bancorp shall promptly notify the Holder of such event; and,
         upon receipt from the Holder of its choice as to the issuer of the
         Substitute Option, the Acquiring Corporation and Hanover Bancorp shall
         promptly compute the number of shares of Substitute Common Stock for
         which the Substitute Option is exercisable and furnish to the Holder a

The Board of Directors
Sterling Financial Corporation
101 North Pointe Boulevard
Lancaster, PA 17601

Members of the Board:

You have requested that we update our opinion as to the fairness, from a
financial point of view, to the shareholders of Sterling Financial Corporation
("Sterling") of the Agreement and Plan of Merger (the "Agreement") pursuant to
which Hanover Bancorp, Inc. ("Hanover") will combine with and into Sterling by
means of a merger (the "Merger"). Under the terms of the Agreement, each
outstanding share of Hanover common stock will be converted into 0.93 shares of
Sterling common stock.

Garland McPherson & Associates, Inc., as part of its investment banking and bank
consulting business, is routinely engaged in the valuation of financial
institution securities for a variety of purposes, including mergers and
acquisitions, and the determination of adequate consideration in such
transactions.

For purposes of this opinion and the original opinion that was rendered on
January 25, 2000, we reviewed and analyzed information pertaining to the
financial and operating condition of Sterling and Hanover. This review included,
but was not limited to: (i) the Agreement and Plan of Merger; (ii) financial and
other information which was publicly available or provided to us by Sterling and
Hanover; (iii) certain financial information relating to the banking industry in
general; (iv) the respective history of dividends paid by the two institutions;
(v) our evaluation of future prospects for the merged institution; (vi) terms
and conditions of comparable merger transactions and (vii) such other financial
reviews, analyses, and investigations as we deemed appropriate.

In rendering our opinion, we conducted discussions with members of senior
management of Sterling and Hanover concerning their respective businesses and
prospects and have relied on the accuracy and completeness of information and
representations delivered to us by Sterling and Hanover and their officers,
directors, counsel, and other agents. We have not independently verified the
information reviewed by us (either publicly available or provided to us by
Sterling and Hanover) and, in rendering our opinion, have relied upon such
information as being complete and accurate in all material respects.

                                       B-2
<PAGE>   231
We have assumed that the allowances for loan losses indicated on the balance
sheets of Sterling and Hanover as of December 31, 1999 are adequate to cover
such losses. We have not reviewed the loan files of Sterling or Hanover, nor did
we make an independent valuation or appraisal of the assets and liabilities of
Sterling and Hanover.

We assumed that in the course of obtaining the necessary regulatory approvals
for the Merger, no restrictions will be imposed on Hanover that would have a
material adverse effect on the contemplated benefits of the Merger to Sterling.
We further assumed that no change would occur in applicable law or regulation
that would cause a material adverse change in the prospects or operations of
Hanover after the Merger. We express no opinion as to the tax consequences of
the merger to Sterling and its shareholders.

Our conclusion is based on the market, economic and other conditions prevailing
as of the date hereof and the current conditions and prospects of Sterling and
Hanover. Events occurring subsequent to this date could materially affect the
assumptions and conclusions contained in our opinion. We express no opinion as
to what the value of Sterling common stock will be at the time the Merger is
consummated. Our opinion pertains only to the financial consideration of the
Merger and does not constitute a recommendation to the Board of Sterling nor a
recommendation as to how Sterling shareholders should vote with regard to the
Merger.

Based upon and subject to the foregoing, it is our opinion as of the date
hereof, that the exchange ratio and the consideration to be paid by Sterling in
the transaction is fair, from a financial point of view, to the shareholders of
Sterling Financial Corporation

Sincerely,



Garland McPherson & Associates, Inc.

The Board of Directors
Hanover Bancorp, Inc.
33 Carlisle Street
Hanover, Pennsylvania 17331



The Board of Directors:

        You have requested our opinion as to the fairness, from a financial
point of view, to the stockholders of Hanover Bancorp, Inc ("Hanover") of the
exchange ratio governing the exchange of shares of the common stock of Hanover
for shares of common stock of Sterling Financial Corporation ("Sterling") in
connection with the proposed acquisition of Hanover by Sterling pursuant to an
Agreement and Plan of Merger (the "Merger Agreement") dated January 25, 2000 by
and between Hanover and Sterling. Pursuant to the Merger Agreement, Hanover will
merge with and into Sterling, with Sterling being the surviving corporation.

        As is more specifically set forth in the Merger Agreement, upon
consummation of the merger, each outstanding share of Hanover common stock,
except for shares held by Sterling and its subsidiaries or by Hanover and its
subsidiaries (in both cases, other than shares held in a fiduciary capacity or
as a result of debts previously contracted), will be converted into and
exchangeable for 0.93 shares of Sterling common stock. The exchange ratio
referenced is a fixed exchange ratio and consequently the market value of the
consideration to be received by Hanover stockholders will fluctuate with changes
in Sterling's stock price. The Merger Agreement may be terminated under certain
conditions prior to the effective time of the merger by the Board of Directors
of either party based on defined criteria.

        McConnell, Budd & Downes, Inc., as part of its investment banking
business, is regularly engaged in the valuation of bank holding companies and
banks, thrift holding companies and thrifts and their securities in connection
with mergers and acquisitions, negotiated underwritings, private placements,
competitive bidding processes, market making as a NASD market maker, secondary
distributions of listed securities and valuations for corporate, estate and
other purposes. Our experience and familiarity with Hanover includes having
worked as a financial advisor to Hanover throughout the process and negotiations
leading up to the proposed merger with Sterling. In the course of our role as
financial advisor to Hanover in connection with the merger, we have received
fees for our services and will receive additional fees contingent on the
occurrence of certain defined events. While the payment of all or a significant
portion of fees related to financial advisory services provided in connection
with arm's-length mergers and other business combination transactions upon
consummation of such transactions, as is the case with this transaction, might
be viewed as giving such financial advisors a financial interest in the
successful completion of such




                                       C-2
<PAGE>   234
transactions, such compensation arrangements are standard and customary for
transactions of the size and type of this transaction.

        In arriving at our opinion, we have reviewed the Merger Agreement and
the joint proxy statement/prospectus in substantially the form in which this
letter appears as an exhibit. We have also reviewed publicly available business,
financial and shareholder information relating to Hanover and its subsidiaries
and certain publicly available financial and shareholder information relating to
Sterling.

        In connection with the foregoing, we have (i) reviewed Hanover's Annual
Reports to Stockholders, Annual Reports on Form 10-K and related financial
information for the four calendar years ended December 31, 1999 and Hanover's
Quarterly Report on Form 10-Q and related unaudited financial information for
1999; (ii) reviewed Sterling's Annual Reports to Stockholders, Annual Reports on
Form 10-K and related financial information for the four calendar years ended
December 31, 1999 and Sterling's Quarterly Report on Form 10-Q and related
unaudited financial information for 1999; (iii) reviewed certain internal
financial information and financial forecasts, relating to the business,
earnings, cash flows, assets and prospects of the respective companies furnished
to McConnell, Budd & Downes, Inc. by Hanover and Sterling, respectively; (iv)
held discussions with members of the senior management and board of Hanover
concerning the past and current results of operations of Hanover, its current
financial condition and management's opinion of its future prospects; (v) held
discussions with members of senior management of Sterling concerning the past
and current results of operations of Sterling, its current financial condition
and management's opinion of its future prospects; (vi) reviewed the historical
record of reported prices, trading volume and dividend payments for both Hanover
and Sterling common stock; (vii) considered the current state of and future
prospects for the economy of Pennsylvania generally and the relevant market
areas for Hanover and Sterling in particular; (viii) reviewed specific merger
analysis models employed by McConnell, Budd & Downes, Inc. to evaluate potential
business combinations of financial institutions; (ix) reviewed the reported
financial terms of selected recent business combinations in the banking
industry; and (x) performed such other studies and analyses as McConnell, Budd &
Downes, Inc. considered appropriate under the circumstances associated with this
particular transaction.

        In the course of our review and analysis we considered, among other
things, such topics as the historical and projected future contributions of
recurring earnings by the parties, the anticipated future earnings per share
results for the parties on both a combined and stand-alone basis, the potential
to realize significant recurring operating expense reductions and the impact
thereof on projected future earnings per share, the relative capitalization and
capital adequacy of each of the parties, the availability of non-interest income
to each of the parties, the relative asset quality and apparent adequacy of the
reserve for loan losses for each of the parties. We also considered the
composition of deposits and the composition of the loan portfolio of each of
Hanover and Sterling. In addition, we considered the historical trading range,
trading pattern and relative market liquidity of the common shares of each of
the parties. In the conduct of our review and analysis we have relied upon and
assumed, without independent verification, the accuracy and completeness of the
financial information provided to us by Hanover and Sterling and or otherwise
publicly obtainable. In reaching our opinion we have not assumed any
responsibility for the independent verification of such information or any
independent valuation or appraisal of any of the assets or the liabilities of




                                       C-3
<PAGE>   235
either Hanover or Sterling, nor have we obtained from any other source, any
current appraisals of the assets or liabilities of either Hanover or Sterling.
We have also relied on the management of Hanover and Sterling as to the
reasonableness of various financial and operating forecasts and of the
assumptions on which they are based, which were provided to us for use in our
analyses.

        In the course of rendering this opinion, which is being rendered prior
to the receipt of certain required regulatory approvals necessary before
consummation of the merger, we assume that no conditions will be imposed by any
regulatory agency in connection with its approval of the merger that will have a
material adverse effect on the results of operations, the financial condition or
the prospects of Sterling following consummation of the merger.

        Based upon and subject to the foregoing, it is our opinion, that as of
the date of this letter, the exchange ratio is fair to the stockholders of
Hanover from a financial point of view.




                                Very truly yours,




                                McConnell, Budd & Downes, Inc.

                  rights.

         (d)      Notice of dissenters rights. Unless otherwise provided by
                  statute, if a proposed corporate action that would give rise
                  to dissenters rights under this subpart is submitted to a vote
                  at a meeting of shareholders, there shall be included in or
                  enclosed with the notice of meeting:

                  (1)      a statement of the proposed action and a statement
                           that the shareholders have a right to dissent and
                           obtain payment of the fair value of their shares by
                           complying with the terms of this subchapter; and

                  (2)      a copy of this subchapter.

         (e)      Other statutes. The procedures of this subchapter shall also
                  be applicable to any transaction described in any statute
                  other than this part that makes reference to this subchapter
                  for the purpose of granting dissenters rights.

         (f)      Certain provisions of articles ineffective. This subchapter
                  may not be relaxed by any provision of the articles.

                  doctrine abolished) and 2512 (relating to dissenters rights
                  procedure).

SECTION 1572. DEFINITIONS.

The following words and phrases when used in this subchapter shall have the
meanings given to them in this section unless the context clearly indicates
otherwise:

                                       D-4
<PAGE>   240
         "Corporation." The issuer of the shares held or owned by the dissenter
         before the corporate action or the successor by merger, consolidation,
         division, conversion or otherwise of that issuer. A plan of division
         may designate which of the resulting corporations is the successor
         corporation for the purposes of this subchapter. The successor
         corporation in a division shall have sole responsibility for payments
         to dissenters and other liabilities under this subchapter except as
         otherwise provided in the plan of division.

         "Dissenter." A shareholder or beneficial owner who is entitled to and
         does assert dissenters rights under this subchapter and who has
         performed every act required up to the time involved for the assertion
         of those rights.

         "Fair value." The fair value of shares immediately before the
         effectuation of the corporate action to which the dissenter objects,
         taking into account all relevant factors, but excluding any
         appreciation or depreciation in anticipation of the corporate action.

         "Interest." Interest from the effective date of the corporate action
         until the date of payment at such rate as is fair and equitable under
         all of the circumstances, taking into account all relevant factors,
         including the average rate currently paid by the corporation on its
         principal bank loans.

SECTION 1573. RECORD AND BENEFICIAL HOLDERS AND OWNERS.

         (a)      Record holders of shares. A record holder of shares of a
                  business corporation may assert dissenters rights as to fewer
                  than all of the shares registered in his name only if he
                  dissents with respect to all the shares of the same class or
                  series beneficially owned by any one person and discloses the
                  name and address of the person or persons on whose behalf he
                  dissents. In that event, his rights shall be determined as if
                  the shares as to which he has dissented and his other shares
                  were registered in the names of different shareholders.

         (b)      Beneficial owners of shares. A beneficial owner of shares of a
                  business corporation who is not the record holder may assert
                  dissenters rights with respect to shares held on his behalf
                  and shall be treated as a dissenting shareholder under the
                  terms of this subchapter if he submits to the corporation not
                  later than the time of the assertion of dissenters rights a
                  written consent of the record holder. A beneficial owner may
                  not dissent with respect to some but less than all shares of
                  the same class or series owned by the owner, whether or not
                  the shares so owned by him are registered in his name.

SECTION 1574. NOTICE OF INTENTION TO DISSENT.

         If the proposed corporate action is submitted to a vote at a meeting of
         shareholders of a business corporation, any person who wishes to
         dissent and obtain payment of the fair value of his shares must file
         with the corporation, prior to the vote, a written notice of intention
         to demand that he be paid the fair value for his shares if the proposed
         action is effectuated, must

                                       D-5
<PAGE>   241
         effect no change in the beneficial ownership of his shares from the
         date of such filing continuously through the effective date of the
         proposed action and must refrain from voting his shares in approval of
         such action. A dissenter who fails in any respect shall not acquire any
         right to payment of the fair value of his shares under this subchapter.
         Neither a proxy nor a vote against the proposed corporate action shall
         constitute the written notice required by this section.



SECTION 1575. NOTICE TO DEMAND PAYMENT.

         (a)      General rule. If the proposed corporate action is approved by
                  the required vote at a meeting of shareholders of a business
                  corporation, the corporation shall mail a further notice to
                  all dissenters who gave due notice of intention to demand
                  payment of the fair value of their shares and who refrained
                  from voting in favor of the proposed action. If the proposed
                  corporate action is to be taken without a vote of
                  shareholders, the corporation shall send to all shareholders
                  who are entitled to dissent and demand payment of the fair
                  value of their shares a notice of the adoption of the plan or
                  other corporate action. In either case, the notice shall:

                  (1)      State where and when a demand for payment must be
                           sent and certificates for certificated shares must be
                           deposited in order to obtain payment.

                  (2)      Inform holders of uncertificated shares to what
                           extent transfer of shares will be restricted from the
                           time that demand for payment is received.

                  (3)      Supply a form for demanding payment that includes a
                           request for certification of the date on which the
                           shareholder, or the person on whose behalf the
                           shareholder dissents, acquired beneficial ownership
                           of the shares.

                  (4)      Be accompanied by a copy of this subchapter.

         (b)      Time for receipt of demand for payment. The time set for
                  receipt of the demand and deposit of certificated shares shall
                  be not less than 30 days from the mailing of the notice.

SECTION 1576. FAILURE TO COMPLY WITH NOTICE TO DEMAND PAYMENT, ETC.

         (a)      Effect of failure of shareholder to act. A shareholder who
                  fails to timely demand payment, or fails (in the case of
                  certificated shares) to timely deposit certificates, as
                  required by a notice pursuant to section 1575 (relating to
                  notice to demand payment) shall not have any right under this
                  subchapter to receive payment of the fair value of his shares.

                                       D-6
<PAGE>   242
         (b)      Restriction on uncertificated shares. If the shares are not
                  represented by certificates, the business corporation may
                  restrict their transfer from the time of receipt of demand for
                  payment until effectuation of the proposed corporate action or
                  the release of restrictions under the terms of section 1577(a)
                  (relating to failure to effectuate corporate action).

         (c)      Rights retained by shareholder. The dissenter shall retain all
                  other rights of a shareholder until those rights are modified
                  by effectuation of the proposed corporate action.

SECTION 1577. RELEASE OF RESTRICTIONS OR PAYMENT FOR SHARES.

         (a)      Failure to effectuate corporate action. Within 60 days after
                  the date set for demanding payment and depositing
                  certificates, if the business corporation has not effectuated
                  the proposed corporate action, it shall return any
                  certificates that have been deposited and release
                  uncertificated shares from any transfer restrictions imposed
                  by reason of the demand for payment.

         (b)      Renewal of notice to demand payment. When uncertificated
                  shares have been released from transfer restrictions and
                  deposited certificates have been returned, the corporation may
                  at any later time send a new notice conforming to the
                  requirements of section 1575 (relating to notice to demand
                  payment), with like effect.

         (c)      Payment of fair value of shares. Promptly after effectuation
                  of the proposed corporate action, or upon timely receipt of
                  demand for payment if the corporate action has already been
                  effectuated, the corporation shall either remit to dissenters
                  who have made demand and (if their shares are certificated)
                  have deposited their certificates the amount that the
                  corporation estimates to be the fair value of the shares, or
                  give written notice that no remittance under this section will
                  be made. The remittance or notice shall be accompanied by:

                  (1)      The closing balance sheet and statement of income of
                           the issuer of the shares held or owned by the
                           dissenter for a fiscal year ending not more than 16
                           months before the date of remittance or notice
                           together with the latest available interim financial
                           statements.

                  (2)      A statement of the corporation's estimate of the fair
                           value of the shares.

                  (3)      A notice of the right of the dissenter to demand
                           payment or supplemental payment, as the case may be,
                           accompanied by a copy of this subchapter.

         (d)      Failure to make payment. If the corporation does not remit the
                  amount of its estimate of the fair value of the shares as
                  provided by subsection (c), it shall return any certificates
                  that have been deposited and release uncertificated shares
                  from any transfer

                                       D-7
<PAGE>   243
                  restrictions imposed by reason of the demand for payment. The
                  corporation may make a notation on any such certificate or on
                  the records of the corporation relating to any such
                  uncertificated shares that such demand has been made. If
                  shares with respect to which notation has been so made shall
                  be transferred, each new certificate issued therefor or the
                  records relating to any transferred uncertificated shares
                  shall bear a similar notation, together with the name of the
                  original dissenting holder or owner of such shares. A
                  transferee of such shares shall not acquire by such transfer
                  any rights in the corporation other than those that the
                  original dissenter had after making demand for payment of
                  their fair value.


SECTION 1578. ESTIMATE BY DISSENTER OF FAIR VALUE OF SHARES.

         (a)      General rule. If the business corporation gives notice of its
                  estimate of the fair value of the shares, without remitting
                  such amount, or remits payment of its estimate of the fair
                  value of a dissenter's shares as permitted by section 1577(c)
                  (relating to payment of fair value of shares) and the
                  dissenter believes that the amount stated or remitted is less
                  than the fair value of his shares, he may send to the
                  corporation his own estimate of the fair value of the shares,
                  which shall be deemed a demand for payment of the amount or
                  the deficiency.

         (b)      Effect of failure to file estimate. Where the dissenter does
                  not file his own estimate under subsection (a) within 30 days
                  after the mailing by the corporation of its remittance or
                  notice, the dissenter shall be entitled to no more than the
                  amount stated in the notice or remitted to him by the
                  corporation.

SECTION 1579. VALUATION PROCEEDINGS GENERALLY.

         (a)      General rule. Within 60 days after the latest of:

                  (1)      effectuation of the proposed corporate action;

                  (2)      timely receipt of any demands for payment under
                           Section 1575 (relating to notice to demand payment);
                           or

                  (3)      timely receipt of any estimates pursuant to section
                           1578 (relating to estimate by dissenter of fair value
                           of shares);

                  if any demands for payment remain unsettled, the business
                  corporation may file in court an application for relief
                  requesting that the fair value of the shares be determined by
                  the court.

                                       D-8
<PAGE>   244
         (b)      Mandatory joinder of dissenters. All, dissenters, wherever
                  residing, whose demands have not been settled shall be made
                  parties to the proceeding as in an action against their
                  shares. A copy of the application shall be served on each such
                  dissenter. If a dissenter is a nonresident, the copy may be
                  served on him in the manner provided or prescribed by or
                  pursuant to 42 Pa.C.S. Ch. 53 (relating to bases of
                  jurisdiction and interstate and international procedure).

         (c)      Jurisdiction of the court. The jurisdiction of the court shall
                  be plenary and exclusive. The court may appoint an appraiser
                  to receive evidence and recommend a decision on the issue of
                  fair value. The appraiser shall have such power and authority
                  as may be specified in the order of appointment or in any
                  amendment thereof.

         (d)      Measure of recovery. Each dissenter who is made a party shall
                  be entitled to recover the amount by which the fair value of
                  his shares is found to exceed the amount, if any, previously
                  remitted, plus interest.

         (e)      Effect of corporation's failure to file application. If the
                  corporation fails to file an application as provided in
                  subsection (a), any dissenter who made a demand and who has
                  not already settled his claim against the corporation may do
                  so in the name of the corporation at any time within 30 days
                  after the expiration of the 60-day period. If a dissenter does
                  not file an application within the 30-day period, each
                  dissenter entitled to file an application shall be paid the
                  corporation's estimate of the fair value of the shares and no
                  more, and may bring an action to recover any amount not
                  previously remitted.

SECTION 1580. COSTS AND EXPENSES OF VALUATION PROCEEDINGS.

         (a)      General rule. The costs and expenses of any proceeding under
                  section 1579 (relating to valuation proceedings generally),
                  including the reasonable compensation and expenses of the
                  appraiser appointed by the court, shall be determined by the
                  court and assessed against the business corporation except
                  that any part of the costs and expenses may be apportioned and
                  assessed as the court deems appropriate against all or some of
                  the dissenters who are parties and whose action in demanding
                  supplemental payment under section 1578 (relating to estimate
                  by dissenter of fair value of shares) the court finds to be
                  dilatory, obdurate, arbitrary, vexatious or in bad faith.

         (b)      Assessment of counsel fees and expert fees where lack of good
                  faith appears. Fees and expenses of counsel and of experts for
                  the respective parties may be assessed as the court deems
                  appropriate against the corporation and in favor of any or all
                  dissenters if the corporation failed to comply substantially
                  with the requirements of this subchapter and may be assessed
                  against either the corporation or a dissenter, in favor of any
                  other party, if the court finds that the party against whom
                  the fees and expenses are assessed

                                       D-9
<PAGE>   245
                  acted in bad faith or in a dilatory, obdurate, arbitrary or
                  vexatious manner in respect to the rights provided by this
                  subchapter.

         (c)      Award of fees for benefits to other dissenters. If the court
                  finds that the services of counsel for any dissenter were of
                  substantial benefit to other dissenters similarly situated and
                  should not be assessed against the corporation, it may award
                  to those counsel reasonable fees to be paid out of the amounts
                  awarded to the dissenters who were benefitted.

Item 22. Undertakings.

         (a)

         1.       The undersigned Registrant hereby undertakes as follows:

                  (A) To file, during any period in which offers or sales are
being made, a post-effective amendment to this registration statement: (i) to
include any prospectus required by Section 10(a)(3) of the Securities Act; (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; (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 (1)(a)(i) and
(1)(a)(ii) above do not apply if the registration statement is on Form S-3 or
Form S-8 and the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registration pursuant to Section 13 or Section 15(d) of the Exchange Act that
are incorporated by reference in the registration statement.

                  (B) That, for the purpose of determining any liability under
the Securities Act, 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.

                  (C) 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.

         2.       The undersigned registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration

                                      II-4
<PAGE>   250
statement relating to the securities offered therein, and the offering of such
securities at the time shall be deemed to be the initial bona fide offering
thereof.

         3. 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 the reofferings
by persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

            The registrant undertakes that every prospectus (i) that is
filed pursuant to the preceding paragraph, or (ii) that purports to meet the
requirements of Section 10(a)(3) of the Act and is used in connection with an
offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-operative 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.

         4. Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the bylaws of the registrant, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

         (b) The undersigned registrant hereby undertakes to respond to requests
for information that is incorporated by reference into the prospectus pursuant
to Items 4, 10(b), 11, or 13 of this Form, within one (1) 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.

                                      II-5
<PAGE>   251
         (c) The undersigned registrant hereby undertakes to supplement 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.

     RE: Sterling Financial Corporation/Hanover Bancorp, Inc.
         Our File No: 00-537

Dear Messrs Stefan and Scovill:

        We are special counsel to Sterling Financial Corporation (the "Company")
in the Company's acquisition of Hanover Bancorp, Inc. ("Hanover"). In connection
with the transaction, the Company proposes to offer up to 3,733,342 shares of
common stock, par value $5.00 per share (the "Common Stock"), to shareholders of
Hanover. The Common Stock is covered by a Registration Statement on Form S-4
(the "Registration Statement") filed with the Securities and Exchange Commission
under the Securities Act of 1933, as amended. In connection with the
registration of the Common Stock, we have reviewed:

        1.      The Articles of Incorporation of the Company;

        2.      The Bylaws of the Company;

        3.      Resolutions adopted by the Board of Directors of the Company
                relating to the Registration Statement;

        4.      The Agreement and Plan of Reorganization, dated as of January
                25, 2000, by and between the Company and Hanover;

        5.      The Registration Statement; and

        6.      Copies of the certificates representing shares of the Common
                Stock.
<PAGE>   2

        Based on our review of the foregoing, it is our opinion that:

        a.      The Company is a corporation, duly organized, validly existing
                and in good standing under the laws of the Commonwealth of
                Pennsylvania; and

        b.      The Common Stock covered by the Registration Statement has been
                duly authorized and, when issued pursuant to the terms described
                in the Registration Statement and the Agreement, will be legally
                issued by the Company and fully paid and non-assessable.

        We consent to the filing of this opinion as an exhibit to the
Registration Statement and the reference to us in the related Proxy
Statement/Prospectus. In giving this consent, we do not admit that we are
experts within the category of persons whose consent is required under Section 7
of the Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.

                                 Very truly yours,

                                 SHUMAKER WILLIAMS, P.C.

STERLING FINANCIAL CORPORATION                          HANOVER BANCORP, INC.
101 North Pointe Boulevard                              P.O. Box 513
Lancaster, PA  17601                                    25 Carlisle Street
                                                        Hanover, PA  17331-2404

Dear Members of the Boards:

         You have requested our opinion regarding material federal income tax
questions in connection with the transaction contemplated by the Agreement and
Plan of Merger, dated as of January 25, 2000, between Hanover Bancorp, Inc., a
Pennsylvania business corporation and a Bank Holding Company, ("Hanover") and
Sterling Financial Corporation, a Pennsylvania business corporation and a Bank
Holding Company, ("Sterling"), pursuant to which Hanover will merge with and
into Sterling, which will be the surviving corporation.

         At the effective date of the merger (the "Merger"), each share of
Hanover's common stock issued and outstanding immediately prior to the effective
date will, by virtue of the Merger, be converted into the right to receive the
number of shares of Sterling common stock as is provided in Section 2.1 (a) of
the Agreement and Plan of Merger. As a result of the Merger, Bank of Hanover and
Trust Company, a subsidiary of Hanover, shall become a wholly-owned operating
subsidiary of Sterling, subject to the provisions of Section 7.6 of the
Agreement and Plan of Merger.

         Hanover shareholders shall exchange their Hanover common stock
certificates for Sterling common stock certificates, as provided in Section 2.2
of the Agreement and Plan of Merger. No fractional shares of Sterling common
stock will issue. In lieu of fractional shares, shareholders of Hanover will
receive cash in an amount determined pursuant to Section 2.1 (d) of the
Agreement and Plan of Merger. Shareholders of Hanover and Sterling will be
entitled to exercise dissenter's rights in connection with the Merger.

         On the effective date, all Treasury shares of Hanover common stock,
other than trust account shares or shares acquired in connection with debts
previously contracted owned by Hanover or any direct or indirect subsidiary of
Hanover, if any, shall be cancelled.

         On the effective date, each share of Hanover common stock, other than
trust account shares or shares acquired in connection with debts previously
contracted owned by Sterling or any direct or indirect subsidiary of Sterling,
if any, shall be cancelled.

         Each share of Sterling common stock issued and outstanding immediately
prior to the effective date, shall, on and after the effective date, continue to
be issued and outstanding as an identical share of Sterling common stock.

         Each share of Sterling common stock issued and held in the treasury of
Sterling as of the effective date, if any, shall on and after the effective
date, continue to be issued and held in the treasury of Sterling.

         In connection with the opinion set forth below with respect to the
Merger, we have reviewed and relied upon the following documents:

         o        The articles of incorporation, bylaws, and resolutions of
                  Sterling's Board of Directors;

         o        The articles of incorporation, bylaws, and resolutions of
                  Hanover's Board of Directors;

         o        The Agreement and Plan of Merger and all exhibits and
                  attachments to the Agreement;

         o        The Articles of Merger which will be filed in Pennsylvania;

         o        Certificates of Officers of both Sterling and Hanover; and

         o        Other documents as we have deemed relevant or appropriate to
                  our opinion.

         In rendering this Opinion, we have relied upon the accuracy and
authenticity of the information contained in these documents. This Opinion is
further based upon the following assumptions that we have made with your consent
and upon which we are relying:

         o        Hanover shareholders will receive shares of Sterling voting
                  common stock in exchange for their shares of Hanover voting
                  common stock surrendered in the exchange based upon a formula
                  provided in the Agreement and Plan of Merger;

         o        Immediately following the transaction, Sterling will possess
                  all the assets and liabilities possessed by Hanover
                  immediately prior to the transaction;

         o        Sterling will continue the historic business of Hanover or
                  will use a significant portion of Hanover's assets in the
                  continuing business of Sterling, and Sterling will continue to
                  operate The Bank of Hanover and Trust Company as a wholly
                  owned operating subsidiary of Sterling;

         o        The Merger will be consummated in accordance with the
                  Agreement and Plan of Merger, including the satisfaction of
                  all covenants and conditions to the obligations of the parties
                  without amendment or waiver thereof;

         o        The Merger will qualify as a merger under the applicable laws
                  of the Commonwealth of Pennsylvania; and

         o        The Agreement and Plan of Merger and all other documents and
                  instruments referred to therein are valid and binding in
                  accordance with their terms.

         Based upon the foregoing facts, documents and assumptions, it is our
opinion that for United States Federal Income Tax purposes:

         o        The Merger of Hanover into Sterling will constitute a
                  "reorganization" within the meaning of Section 368(a)(1)(A) of
                  the Internal Revenue Code of 1986, as amended and Hanover and
                  Sterling will each be a party to the "reorganization" within
                  the meaning of Section 368(b) of the Code;

         o        No gain or loss will be recognized by Hanover or Sterling as a
                  result of the Merger;

         o        No gain or loss will be recognized by the shareholders upon
                  the exchange of their shares of Hanover voting common stock
                  solely for shares of Sterling voting common stock pursuant to
                  the Merger;

         o        The aggregate tax basis of the shares of Sterling voting
                  common stock received solely in exchange for shares of Hanover
                  voting common stock pursuant to the Merger will be the same as
                  the aggregate tax basis of Hanover voting common stock
                  exchanged therefor;

         o        The holding period for the shares of Sterling voting common
                  stock received in exchange for shares of Hanover voting common
                  stock pursuant to the Merger will include the holding period
                  of the shares of Hanover voting common stock exchanged
                  therefor, provided the shares of Hanover voting common stock
                  were held as capital assets by the shareholder at the
                  effective date of the Merger;

         o        The payment of cash in lieu of fractional share interests of
                  Sterling voting common stock will be treated as if the
                  fractional share interests were distributed as part of the
                  Merger and then redeemed by Sterling. These cash payments will
                  be treated as having been received as a distribution in full
                  payment in exchange for the fractional share interest
                  redeemed, as provided in Section 302(a) of the Code;

         o        As provided in Section 381(c)(2) of the Code and related
                  Treasury Regulations, Sterling will succeed to and take into
                  account the earnings and profits, or deficit earnings and
                  profits, of Hanover as of the Merger. Any deficit in the
                  earnings and profits of Sterling or Hanover will be used only
                  to offset the earnings and profits accumulated after the
                  Merger; and

         o        Pursuant to Section 381(a) of the Code and related Treasury
                  Regulations, Sterling will succeed to and take into account
                  the items of Hanover described in Section 381(c) of the Code.
                  These items will be taken into account by Sterling subject to
                  the conditions and limitations of Sections 381, 382, 383 and
                  384 of the Code and Treasury Regulations thereunder.

                              EMPLOYMENT AGREEMENT

                                   WITNESSETH:

         WHEREAS, the Corporation is a registered bank holding company;

         WHEREAS, the Bank is a subsidiary of the Corporation;

         WHEREAS, Corporation and Bank desire to employ Executive to serve in

                                   AGREEMENT:

         NOW, THEREFORE, the parties hereto, intending to be legally bound,
agree as follows:

1.       EMPLOYMENT. Corporation and Bank hereby employ Executive and Executive
         hereby accepts employment with Corporation and Bank, under the terms
         and conditions set forth in this Agreement. As consideration for this
         Agreement, Executive hereby agrees to release Corporation, Hanover
         Bancorp Inc. and Bank of any obligations, duties or responsibilities,
         and Executive agrees to relinquish any and all rights, including but
         not limited to any payments, compensation or sums of money he may
         otherwise be entitled, or he may have, under the Severance Agreement
         dated March 22, 1995 between Executive, Hanover Bancorp Inc. and Bank.

2.       DUTIES OF EMPLOYEE. Executive shall perform and discharge well and
         faithfully such duties as an executive officer of Corporation and Bank
         as may be assigned to Executive from time to time by the Board of
         Directors of Corporation and Bank and the Chairman and President of the
         Corporation so long as the assignment is consistent with the
         Executive's office and duties. Executive shall be employed as Executive
         Vice President of Corporation and President and Chief Executive Officer
         of Bank, and shall hold such other titles as may be given to him from
         time to time by the Board of Directors of Corporation and Bank.

         business of Corporation and Bank during the Employment Period (as
         defined in Section 3 of this Agreement); provided, however, that this
         Section 2 shall not be construed as preventing Executive from
<PAGE>   2
         (a) engaging in activities incident or necessary to personal
         investments so long as such investment does not exceed 5% of the
         outstanding shares of any publicly held company, (b) acting as a member
         of the Board of Directors of any other corporation or as a member of
         the Board of Trustees of any other organization, with the prior
         approval of the Board of Directors of Corporation and Bank, or (c)
         being involved in any other activity with the prior approval of the
         Board of Directors of Corporation and Bank. The Executive shall not
         engage in any business or commercial activities, duties or pursuits
         which compete with the business or commercial activities of Corporation
         or Bank, nor may the Executive serve as a director or officer or in any
         other capacity in a company which competes with Corporation or Bank.

3.       TERM OF AGREEMENT.

         (a)      This Agreement shall be for a three (3) year period (the
                  "Employment Period") beginning on the Effective Date as set
                  forth in Section 1.1(c) of the Agreement and Plan of Merger
                  between Corporation and Hanover Bancorp, Inc. (the "Effective
                  Date") (the "Agreement and Plan of Merger"), and if not
                  previously terminated pursuant to the terms of this Agreement,
                  the Employment Period shall end three (3) years later;
                  provided however, that this Agreement will be automatically
                  renewed on the first anniversary date of the Effective Date
                  (the "Renewal Date") for the three-year period commencing on
                  such date and ending three years later, unless either party
                  gives written notice of nonrenewal to the other party at least
                  sixty (60) days prior to the Renewal Date (in which case this
                  Agreement will continue in effect for a term ending two years
                  from the Renewal Date). If this Agreement is renewed on the
                  Renewal Date, it will be automatically renewed on the first
                  anniversary date of the Renewal Date and each subsequent year
                  (the "Annual Renewal Date") for a period ending three years
                  from each Annual Renewal Date, unless either party gives
                  written notice of non renewal to the other party at least
                  sixty (60) days prior to an Annual Renewal (in which case this
                  Agreement will continue in effect for a term ending two years
                  from the Annual Renewal Date immediately following such
                  notice). If the Agreement and Plan of Merger is terminated
                  pursuant to its terms, the parties hereto shall have no
                  further obligations under this Agreement and this Agreement
                  shall be null and void.

         (b)      Notwithstanding the provisions of Section 3(a) of this
                  Agreement, this Agreement shall terminate automatically for
                  Cause (as defined herein) upon written notice from the Board
                  of Directors of each of Corporation and Bank to Executive. As
                  used in this Agreement, "Cause" shall mean any of the
                  following:

                  (i)      Executive's conviction of or plea of guilty or nolo

                           crime involving moral turpitude, or the actual
                           incarceration of Executive for a period of forty five
                           (45) consecutive days or more;

                  (ii)     Executive's failure to follow the good faith lawful
                           instructions of the Board of Directors of Corporation
                           or Bank with respect to its operations, after

                                        2
<PAGE>   3
                           written notice from Corporation or Bank and a failure
                           to cure such violation within thirty (30) days of
                           said written notice;

                  (iii)    Executive's willful failure to substantially perform
                           Executive's duties to Corporation or Bank, other than
                           a failure resulting from Executive's incapacity
                           because of physical or mental illness, as provided in
                           subsection (d) of this Section 3, after written
                           notice from Corporation or Bank and a failure to cure
                           such violation within thirty (30) days of said
                           written notice;

                  (iv)     Executive's intentional violation of the provisions
                           of this Agreement, after written notice from
                           Corporation or Bank and a failure to cure such
                           violation within thirty (30) days of said written
                           notice;

                  (v)      dishonesty of the Executive in the performance of his
                           duties;

                  (vi)     Executive's removal or prohibition from being an
                           institutional-affiliated party by a final order of an
                           appropriate federal banking agency pursuant to
                           Section 8(e) of the Federal Deposit Insurance Act or
                           by the Office of the Comptroller of the Currency
                           pursuant to national law;

                  (vii)    conduct on the part of the Executive as determined by
                           an affirmative vote of seventy percent (70%) of the
                           disinterested members of the Board of Directors of
                           Corporation and Bank which brings public discredit to
                           Corporation or Bank; or

                  (viii)   Executive's breach of fiduciary duty involving
                           personal profit.

                  If this Agreement is terminated for Cause, all of Executive's
                  rights under this Agreement shall cease as of the effective
                  date of such termination.

         (c)      Notwithstanding the provisions of Section 3(a) of this
                  Agreement, this Agreement shall terminate automatically upon
                  Executive's voluntary termination of employment (other than in
                  accordance with Section 5 of this Agreement) for Good Reason.
                  The term "Good Reason" shall mean (i) the assignment of duties
                  and responsibilities inconsistent with Executive's status as
                  Executive Vice President of Corporation and President and
                  Chief Executive Officer of Bank, (ii) a reassignment which
                  requires Executive to move his principal residence more than
                  fifty (50) miles from the Corporation's and Bank's principal
                  executive office immediately prior to this Agreement, (iii)
                  any removal of the Executive from office or any adverse change
                  in the terms and conditions of the Executive's employment,
                  except for any termination of the Executive's employment under
                  the provisions of Section 3(b) hereof, (iv) any reduction in
                  the Executive's Annual Base Salary as in effect on the date
                  hereof or as the same may be increased from time to time,
                  except such reductions that are the result of a national
                  financial depression, or national or bank emergency, or (v)
                  any failure of Corporation and Bank to provide the Executive
                  with benefits at least as

                                        3
<PAGE>   4
                  favorable as those enjoyed by the Executive during the
                  Employment Period under any of the pension, life insurance,
                  medical, health and accident, disability or other employee
                  plans of Corporation and Bank, or the taking of any action
                  that would materially reduce any of such benefits unless such
                  reduction is part of a reduction applicable to all employees.
                  If such termination occurs for Good Reason, then Corporation
                  or Bank shall pay Executive an amount equal to the remaining
                  balance of the Agreed Compensation otherwise due to the
                  Executive for the remainder of the then existing Employment
                  Period, which amount shall be payable in equal monthly
                  installments and shall be subject to federal, state and local
                  tax withholdings. In addition, for the remainder of the then
                  existing Employment Period, or until Executive secures
                  substantially similar benefits through other employment,
                  whichever shall first occur, Executive shall receive a
                  continuation of all life, disability, medical insurance and
                  other normal health and welfare benefits in effect with
                  respect to Executive during the two (2) years prior to his
                  termination of employment, or, if Corporation and Bank cannot
                  provide such benefits because Executive is no longer an
                  employee, a dollar amount equal to the cost to Executive of
                  obtaining such benefits (or substantially similar benefits).
                  If permitted under the terms of the plan, Executive shall
                  receive the additional retirement benefits to which he would
                  have been entitled had his employment continued through the
                  remaining term of the Agreement. In lieu of continued pension,
                  welfare and other benefits, Executive may elect to receive a
                  lump sum cash payment equal to 25% of the payments to be
                  received for termination of the Agreement under this
                  provision. However, in the event the payment described herein,
                  when added to all other amounts or benefits provided to or on
                  behalf of the Executive in connection with his termination of
                  employment, would result in the imposition of an excise tax
                  under Code Section 4999, such payments shall be retroactively
                  (if necessary) reduced to the extent necessary to avoid such
                  excise tax imposition. Upon written notice to Executive,
                  together with calculations of Corporation's independent
                  auditors, Executive shall remit to Corporation the amount of
                  the reduction plus such interest as may be necessary to avoid
                  the imposition of such excise tax. Notwithstanding the
                  foregoing or any other provision of this contract to the
                  contrary, if any portion of the amount herein payable to the
                  Executive is determined to be non-deductible pursuant to the
                  regulations promulgated under Section 280G of the Internal
                  Revenue Code of 1986, as amended (the "Code"), the Corporation
                  shall be required only to pay to Executive the amount
                  determined to be deductible under Section 280G.

                  At the option of the Executive, exercisable by the Executive
                  within ninety (90) days after the occurrence of the event
                  constituting "Good Reason," the Executive may resign from
                  employment under this Agreement by a notice in writing (the
                  "Notice of Termination") delivered to Corporation and Bank and
                  the provisions of this Section 3(c) hereof shall thereupon
                  apply.

         (d)      Notwithstanding the provisions of Section 3(a) of this
                  Agreement, this Agreement shall terminate automatically upon
                  Executive's Disability and Executive's rights under this
                  Agreement shall cease as of the date of such termination;
                  provided,

                  however, that Executive shall nevertheless be entitled to
                  receive any benefits that may be available under any
                  disability plan of Corporation and Bank, until the earliest of
                  (i) Executive's return to employment, (ii) his attainment of
                  age 65, or (iii) his death. In addition, Executive shall
                  receive for such period a continuation of all life,
                  disability, medical insurance and other normal health and
                  welfare benefits in effect with respect to Executive during
                  the two (2) years prior to his disability, or, if Corporation
                  and Bank cannot provide such benefits because Executive is no
                  longer an employee, a dollar amount equal to the cost to
                  Executive of obtaining such benefits (or substantially similar
                  benefits). For purposes of this Agreement, the Executive shall
                  have a Disability if, as a result of physical or mental injury
                  or impairment, Executive is unable to perform all of the
                  essential job functions of his position on a full time basis
                  with or without a reasonable accommodation and without posting
                  a direct threat to himself and others, for a period of one
                  hundred eighty (180) days. The Executive shall have no duty to
                  mitigate any payment provided for in this Section 3(d) by
                  seeking other employment.

         (e)      Executive agrees that in the event his employment under this
                  Agreement is terminated, Executive shall resign as a director
                  of Corporation and Bank, or any affiliate or subsidiary
                  thereof, if he is then serving as a director of any of such
                  entities.

         (f)      The term "Agreed Compensation" shall equal the sum of (A) the
                  Executive's highest Annual Base Salary under the Agreement,
                  and (B) the average of the Executive's annual bonuses with
                  respect to the three (3) calendar years immediately preceding
                  the Executive's termination.

         (g)      In the event that this Agreement expires by its terms in
                  accordance with the provisions of Section 3(a) and other than
                  for Cause, the Bank will pay Executive within thirty (30) days
                  following termination of the Agreement and upon the receipt of
                  a mutually agreed release an amount equal to 2.0 times the
                  Executive's Agreed Compensation.

4.       EMPLOYMENT PERIOD COMPENSATION.

         (a)      Annual Base Salary. For services performed by Executive under
                  this Agreement, Corporation or Bank shall pay Executive an
                  Annual Base Salary during the Employment Period at the rate of
                  $217,500 per year (subject to applicable withholdings and
                  deductions) payable at the same times as salaries are payable
                  to other executive employees of Corporation or Bank.
                  Corporation or Bank may, from time to time, increase
                  Executive's Annual Base Salary, and any and all such increases
                  shall be deemed to constitute amendments to this Section 4(a)
                  to reflect the increased amounts, effective as of the date
                  established for such increases by the Board of Directors of
                  Corporation or Bank or any committee of such Board in the
                  resolutions authorizing such increases.

         (b)      Bonus. For services performed by Executive under this
                  Agreement, Corporation or Bank may, from time to time, pay a
                  bonus or bonuses to Executive as Corporation or Bank, in its
                  sole discretion, deems appropriate. The payment of any such
                  bonuses shall not reduce or otherwise affect any other
                  obligation of Corporation or Bank to Executive provided for in
                  this Agreement. Executive is entitled to participate in the
                  bonus programs available to senior executives.

         (c)      Paid Time Off and/or Vacations. During the term of this
                  Agreement, Executive shall be entitled to paid time off and/or
                  vacation in accordance with the policies as established from
                  time to time by the Boards of Directors of Corporation and
                  Bank for the Corporation's and Bank's senior management.
                  However, Executive shall not be entitled to receive any
                  additional compensation from Corporation and Bank for failure
                  to take paid time off and/or vacation, nor shall Executive be
                  able to accumulate unused paid time off and/or vacation time
                  from one year to the next, except to the extent authorized by
                  the Boards of Directors of Corporation and Bank.

         (d)      Automobile. During the term of this Agreement, Corporation and
                  Bank shall provide Executive with exclusive use of an
                  automobile mutually agreed upon by Corporation and Bank and
                  reasonably consistent with Executive's position. Corporation
                  and Bank shall be responsible and shall pay for all costs of
                  insurance coverage, repairs, maintenance and other operating
                  and incidental expenses, including license, fuel and oil.
                  Corporation and Bank shall provide Executive with a
                  replacement automobile at approximately the time Executive's
                  automobile reaches three (3) years of age or 50,000 miles,
                  whichever is first, and approximately every three (3) years or
                  50,000 miles thereafter, upon the same terms and conditions.

         (e)      Employee Benefit Plans. During the term of this Agreement,
                  Executive shall be entitled to participate in or receive the
                  benefits of any employee benefit plan currently in effect at
                  Corporation and Bank, subject to the terms of said plan, until
                  such time that the Boards of Directors of Corporation and Bank
                  authorize a change in such benefits. Corporation and Bank
                  shall not make any changes in such plans or benefits which
                  would adversely affect Executive's rights or benefits
                  thereunder, unless such change occurs pursuant to a program
                  applicable to all executive officers of Corporation and Bank
                  and does not result in a proportionately greater adverse
                  change in the rights of or benefits to Executive as compared
                  with any other executive officer of Corporation and Bank.
                  Nothing paid to Executive under any plan or arrangement
                  presently in effect or made available in the future shall be
                  deemed to be in lieu of the salary payable to Executive
                  pursuant to Section 4(a) hereof.

         (f)      Business Expenses. During the term of this Agreement,
                  Executive shall be entitled to receive prompt reimbursement
                  for all reasonable expenses incurred by him, which are
                  properly accounted for, in accordance with the policies and
                  procedures established by the Boards of Directors of
                  Corporation and Bank for their executive officers. Corporation
                  and Bank shall reimburse Executive for any and all dues and
                  reasonable related business expenses associated with the
                  Executive's membership in

                                        6

                  a country club, social club or service organization, including
                  but not limited to, The Hanover Country Club.

         (g)      Stock Options. Executive shall be entitled to participate in
                  the Corporation's stock option plans consistent with his
                  position as a member of Corporation's and Bank's senior
                  management. Upon a Change in Control (as defined in Section
                  5(b) of this Agreement), all options theretofore granted to
                  the Executive by the Corporation and not previously
                  exercisable shall become fully exercisable to the same extent
                  and in the same manner as if they had become exercisable by
                  passage of time or by virtue of the Corporation achieving
                  certain performance objectives in accordance with the relevant
                  provisions of any plan and any agreement.

5.       TERMINATION OF EMPLOYMENT FOLLOWING CHANGE IN CONTROL.

         (a)      If a Change in Control (as defined in Section 5(b) of this
                  Agreement) shall occur, then, at the option of Executive,
                  exercisable by Executive within three hundred sixty five (365)
                  days of the Change in Control, Executive may resign from
                  employment with Corporation and Bank (or, if involuntarily
                  terminated, give notice of intention to collect benefits under
                  this Agreement) by delivering a notice in writing (the "Notice
                  of Termination") to Corporation and Bank and the provisions of
                  Section 6 of this Agreement shall apply.

         (b)      As used in this Agreement, "Change in Control" shall mean the
                  occurrence of any of the following:

                  (i)      (A) a merger, consolidation or division involving
                           Corporation or Bank, (B) a sale, exchange, transfer
                           or other disposition of substantially all of the
                           assets of Corporation or Bank, or (C) a purchase by
                           Corporation or Bank of substantially all of the
                           assets of another entity, unless (y) such merger,
                           consolidation, division, sale, exchange, transfer,
                           purchase or disposition is approved in advance by
                           seventy percent (70%) or more of the members of the
                           Board of Directors of Corporation or Bank (of the
                           entity affected by the transaction) who are not
                           interested in the transaction and (z) a majority of
                           the members of the Board of Directors of the legal
                           entity resulting from or existing after any such
                           transaction and of the Board of Directors of such
                           entity's parent corporation, if any, are former
                           members of the Board of Directors of Corporation or
                           Bank (of the entity affected by the transaction);
                           provided, however, that the provisions of (y) and (z)
                           above shall not apply to the merger of Bank within
                           three (3) years of the Effective Date in which the
                           Bank is the not surviving entity; or

                  (ii)     any "person" (as such term is used in Sections 13(d)
                           and 14(d) of the Securities Exchange Act of 1934 (the
                           "Exchange Act")), other than Corporation or Bank or
                           any "person" who on the date hereof is a director or
                           officer of Corporation or Bank is or becomes the
                           "beneficial owner" (as

                                        7
<PAGE>   8
                           defined in Rule 13d-3 under the Exchange Act),
                           directly or indirectly, of securities of Corporation
                           or Bank representing twenty-five (25%) percent or
                           more of the combined voting power of Corporation or
                           Bank's then outstanding securities, or

                  (iii)    during any period of two (2) consecutive years during
                           the term of Executive's employment under this
                           Agreement, individuals who at the beginning of such
                           period constitute the Board of Directors of
                           Corporation or Bank cease for any reason to
                           constitute at least a majority thereof, unless the
                           election of each director who was not a director at
                           the beginning of such period has been approved in
                           advance by directors representing at least two-thirds
                           of the directors then in office who were directors at
                           the beginning of the period; or

                  (iv)     any other change in control of Corporation and Bank
                           similar in effect to any of the foregoing.

6.       RIGHTS IN EVENT OF TERMINATION OF EMPLOYMENT FOLLOWING CHANGE IN
         CONTROL.

         (a)      In the event that Executive delivers a Notice of Termination
                  (as defined in Section 5(a) of this Agreement) to Corporation
                  and Bank, Executive shall be entitled to receive the
                  compensation and benefits set forth below:

                  If, at the time of termination of Executive's employment, a
                  "Change in Control" (as defined in Section 5(b) of this
                  Agreement) has also occurred, Corporation and Bank shall pay
                  Executive a lump sum amount equal to and no greater than 2.99
                  times the Executive's Agreed Compensation as defined in
                  subsection (f) of Section 3, (the payment of which shall be
                  subject to applicable taxes and withholdings). In addition,
                  for a period of three (3) years from the date of termination
                  of employment, or until Executive secures substantially
                  similar benefits through other employment, whichever shall
                  first occur, Executive shall receive a continuation of all
                  life, disability, medical insurance and other normal health
                  and welfare benefits in effect with respect to Executive
                  during the two (2) years prior to his termination of
                  employment, or, if Corporation and Bank cannot provide such
                  benefits because Executive is no longer an employee, a dollar
                  amount equal to the cost to Executive of obtaining such
                  benefits (or substantially similar benefits). If permitted
                  under the terms of the plan, Executive shall receive
                  additional retirement benefits to which he would have been
                  entitled had his employment continued through the then
                  remaining term of the Agreement. In lieu of continued pension,
                  welfare and other benefits, Executive may elect to receive a
                  lump sum cash payment equal to 25% of the payments to be
                  received for termination of the Agreement under this
                  provision. However, in the event the payment described herein,
                  when added to all other amounts or benefits provided to or on
                  behalf of the Executive in connection with his termination of
                  employment, would result in the imposition of an excise tax
                  under Code Section 4999, such payments shall be retroactively
                  (if necessary) reduced to the extent necessary to avoid such
                  excise tax imposition. Upon written notice to

                                        8
<PAGE>   9
                  Executive, together with calculations of Corporation's
                  independent auditors, Executive shall remit to Corporation the
                  amount of the reduction plus such interest as may be necessary
                  to avoid the imposition of such excise tax. Notwithstanding
                  the foregoing or any other provision of this contract to the
                  contrary, if any portion of the amount herein payable to the
                  Executive is determined to be non-deductible pursuant to the
                  regulations promulgated under Section 280G of the Code, the
                  Corporation shall be required only to pay to Executive the
                  amount determined to be deductible under Section 280G.

         (b)      Executive shall not be required to mitigate the amount of any
                  payment provided for in this Section 6 by seeking other
                  employment or otherwise. Unless otherwise agreed to in
                  writing, the amount of payment or the benefit provided for in
                  this Section 6 shall not be reduced by any compensation earned
                  by Executive as the result of employment by another employer
                  or by reason of Executive's receipt of or right to receive any
                  retirement or other benefits after the date of termination of
                  employment or otherwise.

7.       RIGHTS IN EVENT OF TERMINATION OF EMPLOYMENT ABSENT CHANGE IN CONTROL.

         (a)      In the event that Executive's employment is involuntarily
                  terminated by Corporation and/or Bank without Cause and no
                  Change in Control shall have occurred at the date of such
                  termination, Corporation and Bank shall pay Executive an
                  amount equal to 2.0 times the Executive's Agreed Compensation
                  or the remaining balance of the Agreed Compensation otherwise
                  due to the Executive for the remainder of the then existing
                  Employment Period, whichever is greater, and shall be payable
                  in equal monthly installments and shall be subject to federal,
                  state and local tax withholdings. In addition, for the
                  remainder of the then existing Employment Period or until
                  Executive secures substantially similar benefits through other
                  employment, whichever shall first occur, Executive shall
                  receive a continuation of all life, disability, medical
                  insurance and other normal health and welfare benefits in
                  effect with respect to Executive during the two (2) years
                  prior to his termination of employment, or, if Corporation and
                  Bank cannot provide such benefits because Executive is no
                  longer an employee, a dollar amount equal to the cost to
                  Executive of obtaining such benefits (or substantially similar
                  benefits). In addition, if permitted pursuant to the terms of
                  the plan, Executive shall receive additional retirement
                  benefits to which he would have been entitled had his
                  employment continued through the then remaining term of the
                  Agreement. In lieu of continued pension, welfare and other
                  benefits, Executive may elect to receive a lump sum cash
                  payment equal to 25% of the payments to be received for
                  termination of the Agreement under this provision. However, in
                  the event the payment described herein, when added to all
                  other amounts or benefits provided to or on behalf of the
                  Executive in connection with his termination of employment,
                  would result in the imposition of an excise tax under Code
                  Section 4999, such payments shall be retroactively (if
                  necessary) reduced to the extent necessary to avoid such
                  excise tax imposition. Upon written notice to Executive,
                  together with calculations of Corporation's independent
                  auditors,

                                        9
<PAGE>   10
                  Executive shall remit to Corporation the amount of the
                  reduction plus such interest as may be necessary to avoid the
                  imposition of such excise tax. Notwithstanding the foregoing
                  or any other provision of this contract to the contrary, if
                  any portion of the amount herein payable to the Executive is
                  determined to be non-deductible pursuant to the regulations
                  promulgated under Section 280G of the Code, the Corporation
                  shall be required only to pay to Executive the amount
                  determined to be deductible under Section 280G.

         (b)      Executive shall not be required to mitigate the amount of any
                  payment provided for in this Section 7 by seeking other
                  employment or otherwise. Unless otherwise agreed to in
                  writing, the amount of payment or the benefit provided for in
                  this Section 7 shall not be reduced by any compensation earned
                  by Executive as the result of employment by another employer
                  or by reason of Executive's receipt of or right to receive any
                  retirement or other benefits after the date of termination of
                  employment or otherwise.

8.       COVENANT NOT TO COMPETE.

         (a)      Executive hereby acknowledges and recognizes the highly
                  competitive nature of the business of Corporation and Bank and
                  accordingly agrees that, during and for the applicable period
                  set forth in Section 8(c) hereof, Executive shall not, except
                  as otherwise permitted in writing by the Corporation and the
                  Bank:

                  (i)      be engaged, directly or indirectly, either for his
                           own account or as agent, consultant, employee,
                           partner, officer, director, proprietor, investor
                           (except as an investor owning less than 5% of the
                           stock of a publicly owned company) or otherwise of
                           any person, firm, corporation or enterprise engaged
                           in (1) the banking (including bank holding company)
                           or financial services industry, or (2) any other
                           activity in which Corporation or Bank or any of their
                           subsidiaries are engaged during the Employment
                           Period, and remain so engaged at the end of the
                           Employment Period, in any area in which, at any time
                           during the Employment Period or at the date of
                           termination of the Executive's employment, is within
                           thirty (30) miles of any branch location, office or
                           other facility of Corporation or Bank or any of their
                           subsidiaries, unless Executive exclusively performs
                           all such activity outside of said thirty (30) mile
                           area (the "Non-Competition Area"); or

                  (ii)     provide financial or other assistance to any person,
                           firm, corporation, or enterprise engaged in (1) the
                           banking (including bank holding company) or financial
                           services industry, or (2) any other activity in which
                           Corporation or Bank or any of their subsidiaries are
                           engaged during the Employment Period, in the
                           Non-Competition Area; or


                                       10
<PAGE>   11
                  (iii)    if employed in a capacity provided in (i) and (ii),
                           solicit current customers, during the term of this
                           Agreement, of Corporation, Bank or any Corporation
                           subsidiary in the Non-Competition Area; or

                  (iv)     solicit employees of Corporation, Bank or any
                           Corporation subsidiary who are employed during the
                           term of this Agreement.

         (b)      It is expressly understood and agreed that, although Executive
                  and Corporation and Bank consider the restrictions contained
                  in Section 8(a) hereof reasonable for the purpose of
                  preserving for Corporation and Bank and their subsidiaries
                  their good will and other proprietary rights, if a final
                  judicial determination is made by a court having jurisdiction
                  that the time or territory or any other restriction contained
                  in Section 8(a) hereof is an unreasonable or otherwise
                  unenforceable restriction against Executive, the provisions of
                  Section 8(a) hereof shall not be rendered void but shall be
                  deemed amended to apply as to such maximum time and territory
                  and to such other extent as such court may judicially
                  determine or indicate to be reasonable.

         (c)      The provisions of this Section 8 shall be applicable
                  commencing on the date of this Agreement and ending on one of
                  the following dates, as applicable:

                  (i)      if Executive's employment terminates in accordance
                           with the provisions of Section 3(c), the end of the
                           then existing Employment Period; or

                  (ii)     if Executive's employment terminates in accordance
                           with the provisions of Section 3(b) of this Agreement
                           (relating to termination for Cause), the second
                           anniversary date of the effective date of termination
                           of employment; or

                  (iii)    if the Executive voluntarily terminates his
                           employment in accordance with the provisions of
                           Section 5 hereof, the third anniversary date of the
                           effective date of termination of employment; or

                  (iv)     if the Executive's employment is involuntarily
                           terminated in accordance with the provisions of
                           Section 7 hereof, the second anniversary date of the
                           effective date of termination of employment;

                  (v)      if the Agreement expires by its terms in accordance
                           with the provisions of Section 3(a) and other than
                           for Cause, the second anniversary date of the
                           effective date of termination of employment.

9.       UNAUTHORIZED DISCLOSURE. During the term of his employment hereunder,
         or at any later time, the Executive shall not, without the written
         consent of the Boards of Directors of Corporation and Bank or a person
         authorized thereby, knowingly disclose to any person, other than an
         employee of Corporation or Bank or a person to whom disclosure is
         reasonably necessary or appropriate in connection with the performance
         by the Executive of his duties as an executive of Corporation and Bank,
         any material confidential information

                                       11
<PAGE>   12
         obtained by him while in the employ of Corporation and Bank with
         respect to any of Corporation and Bank's services, products,
         improvements, formulas, designs or styles, processes, customers,
         methods of business or any business practices the disclosure of which
         could be or will be damaging to Corporation or Bank; provided, however,
         that confidential information shall not include any information known
         generally to the public (other than as a result of unauthorized
         disclosure by the Executive or any person with the assistance, consent
         or direction of the Executive) or any information of a type not
         otherwise considered confidential by persons engaged in the same
         business of a business similar to that conducted by Corporation and
         Bank or any information that must be disclosed as required by law.

10.      LIABILITY INSURANCE. Corporation and Bank shall use their best efforts
         to obtain insurance coverage for the Executive under an insurance
         policy covering officers and directors of Corporation and Bank against
         lawsuits, arbitrations or other legal or regulatory proceedings;
         however, nothing herein shall be construed to require Corporation
         and/or Bank to obtain such insurance, if the Board of Directors of the
         Corporation and/or Bank determine that such coverage cannot be obtained
         at a reasonable price.

11.      NOTICES. Except as otherwise provided in this Agreement, any notice
         required or permitted to be given under this Agreement shall be deemed
         properly given if in writing and if mailed by registered or certified
         mail, postage prepaid with return receipt requested, to Executive's
         residence, in the case of notices to Executive, and to the principal
         executive offices of Corporation and Bank, in the case of notices to
         Corporation and Bank.

12.      WAIVER. No provision of this Agreement may be modified, waived or
         discharged unless such waiver, modification or discharge is agreed to
         in writing and signed by Executive and an executive officer
         specifically designated by the Boards of Directors of Corporation and
         Bank. No waiver by either party hereto at any time of any breach by the
         other party hereto of, or compliance with, any condition or provision
         of this Agreement to be performed by such other party shall be deemed a
         waiver of similar or dissimilar provisions or conditions at the same or
         at any prior or subsequent time.

13.      ASSIGNMENT. This Agreement shall not be assignable by any party, except
         by Corporation and Bank to any successor in interest to their
         respective businesses.

14.      ATTORNEY'S FEES AND COSTS. If any action at law or in equity is
         necessary to enforce or interpret the terms of this Agreement, the
         prevailing party shall be entitled to reasonable attorney's fees,
         costs, and necessary disbursements in addition to any other relief that
         may be proper.

15.      INDEMNIFICATION. The Corporation will indemnify the Executive, to the
         fullest extent permitted under Pennsylvania and federal law, with
         respect to any threatened, pending or completed legal or regulatory
         action, suit or proceeding brought against him by reason of the fact
         that he is or was a director, officer, employee or agent of the
         Corporation, or is or was serving at the request of the Corporation as
         a director, officer, employee or agent of another person or entity. To
         the fullest extent permitted by Pennsylvania and federal law, the

                                       12
<PAGE>   13
         Corporation will, in advance of final disposition, pay any and all
         expenses incurred by the Executive in connection with any threatened,
         pending or completed legal or regulatory action, suit or proceeding
         with respect to which he may be entitled to indemnification hereunder.

16.      ENTIRE AGREEMENT. This Agreement supersedes any and all agreements,
         either oral or in writing, between the parties with respect to the
         employment of the Executive by the Bank and/or Corporation and this
         Agreement contains all the covenants and agreements between the parties
         with respect to employment.

17.      SUCCESSORS; BINDING AGREEMENT.

         (a)      Corporation and Bank will require any successor (whether
                  direct or indirect, by purchase, merger, consolidation, or
                  otherwise) to all or substantially all of the businesses
                  and/or assets of Corporation and Bank to expressly assume and
                  agree to perform this Agreement in the same manner and to the
                  same extent that Corporation and Bank would be required to
                  perform it if no such succession had taken place. Failure by
                  Corporation and Bank to obtain such assumption and agreement
                  prior to the effectiveness of any such succession shall
                  constitute a breach of this Agreement and the provisions of
                  Section 3 of this Agreement shall apply. As used in this
                  Agreement, "Corporation" and "Bank" shall mean Sterling
                  Financial Corporation and Bank of Hanover and Trust Company,
                  as defined previously and any successor to their respective
                  businesses and/or assets as aforesaid which assumes and agrees
                  to perform this Agreement by operation of law or otherwise.

         (b)      This Agreement shall inure to the benefit of and be
                  enforceable by Executive's personal or legal representatives,
                  executors, administrators, heirs, distributees, devisees and
                  legatees. If Executive should die after a Notice of
                  Termination is delivered by Executive, or following
                  termination of Executive's employment without Cause, and any
                  amounts would be payable to Executive under this Agreement if
                  Executive had continued to live, all such amounts shall be
                  paid in accordance with the terms of this Agreement to
                  Executive's devisee, legatee, or other designee, or, if there
                  is no such designee, to Executive's estate.

18.      ARBITRATION. Corporation, Bank and Executive recognize that in the
         event a dispute should arise between them concerning the interpretation
         or implementation of this Agreement, lengthy and expensive litigation
         will not afford a practical resolution of the issues within a
         reasonable period of time. Consequently, each party agrees that all
         disputes, disagreements and questions of interpretation concerning this
         Agreement are to be submitted for resolution, in Philadelphia,
         Pennsylvania, to the American Arbitration Association (the
         "Association") in accordance with the Association's National Rules for
         the Resolution of Employment Disputes or other applicable rules then in
         effect ("Rules"). Corporation, Bank or Executive may initiate an
         arbitration proceeding at any time by giving notice to the other in
         accordance with the Rules. Corporation and Bank and Executive may, as a
         matter of right, mutually agree on the appointment of a particular
         arbitrator from the Association's pool. The

                                       13
<PAGE>   14
         arbitrator shall not be bound by the rules of evidence and procedure of
         the courts of the Commonwealth of Pennsylvania but shall be bound by
         the substantive law applicable to this Agreement. The decision of the
         arbitrator, absent fraud, duress, incompetence or gross and obvious
         error of fact, shall be final and binding upon the parties and shall be
         enforceable in courts of proper jurisdiction. Following written notice
         of a request for arbitration, Corporation, Bank and Executive shall be
         entitled to an injunction restraining all further proceedings in any
         pending or subsequently filed litigation concerning this Agreement,
         except as otherwise provided herein.

19.      NO MITIGATION OR OFFSET. The Executive will not be required to mitigate
         the amount of any payment provided for in this Agreement by seeking
         employment or otherwise; nor will any amounts or benefits payable or
         provided hereunder be reduced in the event he does not secure
         employment, except as otherwise provided herein.

20.      VALIDITY. The invalidity or unenforceability of any provision of this
         Agreement shall not affect the validity or enforceability of any other
         provision of this Agreement, which shall remain in full force and
         effect.

21.      APPLICABLE LAW. This Agreement shall be governed by and construed in
         accordance with the domestic, internal laws of the Commonwealth of
         Pennsylvania, without regard to its conflicts of laws principles.

22.      HEADINGS. The section headings of this Agreement are for convenience
         only and shall not control or affect the meaning or construction or
         limit the scope or intent of any of the provisions of this Agreement.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first above written.

We ask you to approve the merger of Sterling with Hanover Bancorp, Inc. The
merger is described in the materials we are sending to you and provides for
Hanover's subsidiary, Hanover Bank and Trust Company to become a wholly owned
subsidiary of Sterling after the merger. We are also asking shareholders to
elect five Class of 2003 Directors and to ratify the selection of Ernst & Young,
LLP as the corporation's certified public accountants. We enclose Sterling's
Notice of Annual Meeting, Proxy Statement and proxy card with this letter. We
also enclose the 1999 Annual Report of Sterling Financial Corporation,

Hanover's 1999 Annual Report to Shareholders and Hanover's Annual Report on Form
10-K for the year ended December 31, 1999.

I hope you will take the opportunity to review the material in the Annual
Report, which reflects a successful year in 1999. We will report on Sterling's
1999 business results and other matters of interest to shareholders at this
meeting.

It is important that your shares be represented at the Annual Meeting whether or
not you are personally able to attend or regardless of the number of shares you
own. We urge you to sign and date the enclosed proxy and return it in the
enclosed envelope as soon as possible. If you do attend the meeting and wish to

so that your proxy will be superseded by any ballot that you submit at the

                      STATUTES RELATING TO INDEMNIFICATION

Subchapter D of Chapter 17 of the Pennsylvania Business Corporation Law of 1988,
                (15 Pa.C.S. Sections 17410-1750), as amended


Subchapter D. - Indemnification

SECTION 1741.  Third party actions.

         Unless otherwise restricted in its bylaws, a business corporation shall
have power to indemnify any person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation), by reason of the fact that he is or was
a representative of the corporation, or is or was serving at the request of the
corporation as a representative of another domestic or foreign corporation for
profit or not-for-profit, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with the
action or proceeding if he 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,
with respect to any criminal proceeding, had no reasonable cause to believe his
conduct was unlawful. The termination of any action or proceeding by judgment,
order, settlement or conviction or upon a plea of nolo contendere or its
equivalent shall not of itself create a presumption that the person did not act
in good faith and in a manner that he reasonably believed to be in, or not
opposed to, the best interests of the corporation and, with respect to any
criminal proceeding, had reasonable cause to believe that his conduct was
unlawful.

SECTION 1742.  Derivative actions.

         Unless otherwise restricted in its bylaws, a business corporation shall
have power to indemnify any person who was or is a party, or is threatened to be
made a party, to any threatened, pending or completed action by or in the right
of the corporation to procure a judgment in its favor by reason of the fact that
he is or was a representative of the corporation or is or was serving at the
request of the corporation as a representative of another domestic or foreign
corporation for profit or not-for-profit, partnership, joint venture, trust or
other enterprise, against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection with the defense or settlement of the
action if he acted in good faith and in a manner he reasonably believed to be
in, or not opposed to, the best interests of the corporation. Indemnification
shall not be made under this section in respect of any claim, issue or matter as
to which the person has been adjudged to be liable to the corporation unless and
only to the extent that the court of common pleas of the judicial district
embracing the county in which the registered office of the corporation is
located or the court in which the action was brought determines upon application
that, despite the adjudication of liability but in view of all the
<PAGE>   2
circumstances of the case, the person is fairly and reasonably entitled to
indemnity for the expenses that the court of common pleas or other court deems
proper.

SECTION 1743.  Mandatory indemnification.

         To the extent that a representative of a business corporation has been
successful on the merits or otherwise in defense of any action or proceeding
referred to in section 1741 (relating to third-party actions) or 1742 (relating
to derivative and corporate actions) or in defense of any claim, issue or matter
therein, he shall be indemnified against expenses (including attorney fees)
actually and reasonably incurred by him in connection therewith.

SECTION 1744.  Procedure for effecting indemnification.

         Unless ordered by a court, any indemnification under section 1741
(relating to third-party actions) or 1742 (relating to derivative and corporate
actions) shall be made by the business corporation only as authorized in the
specific case upon a determination that indemnification of the representative is
proper in the circumstances because he has met the applicable standard of
conduct set forth in those sections. The determination shall be made:

         (1)      by the board of directors by a majority vote of a quorum
                  consisting of directors who were not parties to the action or
                  proceedings;

         (2)      if such a quorum is not obtainable or if obtainable and a
                  majority vote of a quorum of disinterested directors so
                  directs, by independent legal counsel in a written opinion; or

         (3)      by the shareholders.

SECTION 1745.  Advancing expenses.

         Expenses (including attorneys' fees) incurred in defending any action
or proceeding referred to in this subchapter may be paid by a business
corporation in advance of the final disposition of the action or proceeding upon
receipt of an undertaking by or on behalf of the representative to repay the
amount if it is ultimately determined that he is not entitled to be indemnified
by the corporation as authorized in this subchapter or otherwise.

SECTION 1746.  Supplementary coverage.

         (a) General rule - The indemnification and advancement of expenses
provided by, or granted pursuant to, the other section of this subchapter shall
not be deemed exclusive of any other rights which a person seeking
indemnification or advancement of expenses may be entitled under any bylaw,
agreement, vote of shareholders or disinterested directors or otherwise, both as
to action in his official capacity and as to action in another capacity while
holding that office. Section 1728 (relating to interested directors or officers;
quorum) and, in the case of a registered corporation, section 2538 relating to
approval of transactions with interested shareholders) shall
<PAGE>   3
be applicable to any bylaw, contract or transaction authorized by the directors
under this section. A corporation may create a fund of any nature, which may,
but need not be, under the control of a trustee, or to otherwise secure or
insure in any manner its indemnification obligations, whether arising under or
pursuant to this section or otherwise.

         (b) When indemnification is not to be made - Indemnification pursuant
to subsection (a) shall not be made in any case where the act or failure to act
giving rise to the claim for indemnification is determined by a court to have
constituted willful misconduct or recklessness. The articles may not provide for
indemnification in the case of willful misconduct or recklessness.

         (c) Grounds - Indemnification pursuant to subsection (a) under any
bylaw, agreement, vote of shareholders or directors or otherwise may be granted
for any action taken and may be made whether or not the corporation would have
the power to indemnify the person under any other provision of law except as
provided in this section and whether or not the indemnified liability arises or
arose from any threatened, pending or completed action by or in the right of the
corporation. Such indemnification is declared to be consistent with the public
policy of this Commonwealth.

SECTION 1747.  Power to purchase insurance.

         Unless otherwise restricted in its bylaws, a business corporation shall
have power to purchase and maintain insurance on behalf of any person who is or
was a representative of the corporation or is or was serving at the request of
the corporation as a representative of another domestic or foreign corporation
for profit or not-for-profit, partnership, joint venture, trust or other
enterprise against any liability asserted against him and incurred by him in any
such capacity, or arising out of his status as such, whether or not the
corporation would have the power to indemnify him against that liability under
the provisions of this subchapter. Such insurance is declared to be consistent
with the public policy of this Commonwealth.

SECTION 1748.  Application to surviving or new corporations.

         For the purposes of this subchapter, references to the "corporation"
include all constituent corporations absorbed in a consolidation, merger or
division, as well as the surviving or new corporations surviving or resulting
therefrom, so that any person who is or was a representative f the constituent,
surviving or new corporation ,or is or was serving at the request of the
constituent, surviving or new corporation as a representative of another
domestic or foreign corporation for profit or not-for-profit, partnership, joint
venture, trust or other enterprise, shall stand in the same position under the
provisions of this subchapter with respect to the surviving or new corporation
as he would if he had served the surviving or new corporation in the same
capacity.

SECTION 1749.  Application to employee benefit plans.

         For the purposes of this subchapter:
<PAGE>   4
         (1)      References to "other enterprises" shall include employee
                  benefit plans and references to "serving at the request of the
                  corporation" shall include any service as a representative of
                  the business corporation that imposes duties on, or involves
                  services by, the representative with respect to an employee
                  benefit plan, its participants or beneficiaries.

         (2)      Excise taxes assessed on a person with respect to an employee
                  benefit plan pursuant to applicable law shall be deemed
                  "fines".

         (3)      Action with respect to an employee benefit plan taken or
                  omitted in good faith by a representative of the corporation
                  in a manner he reasonably believed to be in the interest of
                  the participants and beneficiaries of the plan shall be deemed
                  to be action in a manner that is not opposed to the best
                  interests of the corporation.

SECTION 1750.  Duration and extent of coverage.

         The indemnification and advancement of expenses provided by, or granted
pursuant to, this subchapter shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a representative of the
corporation and shall inure to the benefit of the heirs and personal
representative of that person.
