         Stockholders are requested to complete, date, sign and promptly return
the accompanying proxy card in the enclosed envelope. If the enclosed form of
proxy is properly executed and returned to Bancorp in time to be voted at the
Annual Meeting, the shares represented thereby will, unless such proxy has

however, affecting any vote taken prior to such revocation) by filing with the
Clerk of Bancorp a written notice of revocation, by delivering to Bancorp a duly

                                VOTING SECURITIES


         The Board of Directors has fixed the close of business on March 9, 1998
as the record date (the "Record Date") for determining the stockholders entitled
to notice of and to vote at the Annual Meeting and any adjournments thereof. On
the Record Date there were 3,816,992 shares of Common Stock ("Common Stock") of
Bancorp outstanding. As of the Record Date there were approximately 663 holders
of record of the Common Stock. All such shares carry voting rights and all
stockholders are entitled to cast one vote for each such share held of record at
the close of business on the Record Date upon each matter properly brought
before the Annual Meeting or any adjournment thereof. Holders of the Common
Stock are not entitled to cumulative voting in the election of directors. A
majority of the outstanding shares of Common Stock present in person or by proxy
will constitute a quorum for transaction of business at the Annual Meeting.

         Shares with respect to which votes have been withheld from any director
and shares abstaining from voting, and broker non-votes (i.e., shares
represented in the meeting held by brokers on nominees as to which instructions
have not been received from the beneficial owners entitled to vote such shares
and with respect to which one or more but not all proposals, such brokers or
nominees do not have discretionary voting power), will be counted for purposes
of determining whether a quorum is present at the Annual Meeting for the
transaction of business. Abstentions and broker non-votes will have no effect on
the election of directors or approval of Proposal 2 (approval of the 1998
Incentive and Nonqualified Stock Option Plan).

                                   PROPOSAL 1

                        ELECTION OF A CLASS OF DIRECTORS

         The Board of Directors of Bancorp presently consists of seventeen
members and is divided into three classes as nearly equal in number as possible.
The term of office of one class of Directors expires each year and their
successors are elected at each annual meeting of stockholders for a term of
three years and until their successors are duly elected and qualified.

         At the Annual Meeting, seven Directors will be elected to serve until
the 2001 annual meeting and until their respective successors are duly elected
and qualified. The Board of Directors has nominated Francis L. Conway, Arthur E.
Holden, Stephen G. Kasnet, Linda Lerner, Arthur J. Pappathanasi, George W.
Phillips and John H. Womack for election as Directors to serve until the 2001
annual meeting. Unless otherwise specified in the proxy, it is the intention of
the persons named in the proxy to vote the shares represented by each properly
executed proxy for the election of Ms. Lerner and Messrs. Conway, Holden,
Kasnet, Pappathanasi, Phillips and Womack as Directors. Each of Ms. Lerner and
Messrs. Conway, Holden, Kasnet, Pappathanasi, Phillips and Womack has agreed to
stand for election and to serve if elected as a Director. However, if any person
nominated by the Board of Directors fails to stand for election or is unable to
accept election, the proxies will be voted for the election of such other person
as the Board of Directors may recommend.

         The affirmative vote of holders of a plurality of the shares of Common
Stock represented in person or by proxy at the Annual Meeting is necessary to
elect the nominees as Directors.

THE BOARD OF DIRECTORS AND COMMITTEES OF THE BOARD

         The Board of Directors of Bancorp held 11 meetings during 1997. During
1997 each incumbent Director, except Robert R. Fanning, Jr. and Arthur E.
Holden, attended 75 percent or more of the total of all meetings of the Board of
Directors and the committees of the Board of Directors on which each served
during the period for which he served. The standing committees of the Board
include: an Executive Committee; a Finance, Audit and Compliance Committee and a
Nominating Committee. The Finance, Audit and Compliance Committee and the
Nominating Committee are described below. The Executive Committee of Bancorp,
acting jointly with the Executive Committee of the Bank, of which no employee
Director is a member, is responsible for all compensation matters.

         FINANCE, AUDIT AND COMPLIANCE COMMITTEE. At December 31, 1997, the
Finance, Audit and Compliance Committee consisted of Peter V. Bent, Francis L.
Conway, Robert R. Fanning, Jr., Stephen R. Howe, Chairman, John C. Jeffers,
Linda Lerner, and Arthur J. Pappathanasi. The Finance, Audit and Compliance
Committee reviews and approves the adequacy of management reporting and
financial and accounting control systems, as well as monitoring compliance with
state and federal laws and regulations. The Committee also approves the
selection of independent public accountants, reviews audit and compliance
examinations and reports, and approves and monitors appropriate action based
upon these reports, and reviews and advises with respect to material
transactions with Directors or officers. In addition, the Committee reviews and
approves matters relating to financial management and the capital markets.
Meetings are held as necessary to accomplish the objectives of the Committee,
and in 1997 the Committee met twice.

         NOMINATING COMMITTEE. At December 31, 1997, the Nominating Committee
consisted of Stephen J. Connolly, IV, Robert R. Fanning, Jr., Arthur E. Holden,
Stephen G. Kasnet and Arthur E. McCarthy, Chairman. The Nominating Committee met
once during 1997. The Nominating Committee selects nominees for election as
Directors; determines committee assignments and recommends for Board approval
the policy regarding directors' compensation. Meetings are held as necessary to
accomplish the objectives of the Nominating Committee. The Nominating Committee
will consider written recommendations from any stockholder of record with
respect to nominees for Directors of Bancorp. Such nominations must be delivered
to or mailed to and received by Bancorp at its principal executive office no
later than March 7, 1999 and no earlier than December 7, 1998 to be considered
at the 1999 annual meeting. To submit a nomination, a stockholder should send
the nominee's name and appropriate supporting information as provided in
Bancorp's By-Laws to Susan G. Ouellette, Clerk, at Bancorp's principal executive
office (see "Stockholder Proposals").

                             EXECUTIVE COMPENSATION


COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         The Executive Committees (the "Committees") of the Boards of Directors
of Bancorp and the Bank, which are comprised of the same individuals, are
responsible for compensation policies and decisions. Bancorp does not pay any
separate compensation to the Chief Executive Officer or executive officers of
Bancorp, all of whom are executive officers of the Bank and receive compensation
in such capacities. Neither George W. Phillips, Paul M. Peduto nor John R.
Putney is or was a member of the Executive Committee of Bancorp or the Bank.

         The Committees' policy with regard to executive compensation is as
follows: Salaries and perquisites, other than bonuses and option grants, are
based in part on the Committees' subjective evaluation of (a) publicly available
information concerning salaries and perquisites earned by individuals with
comparable responsibilities and positions at other public companies and (b) the
performance of Bancorp and the Bank and individual executive officers. In the
case of compensation for executive officers other than the Chief Executive
Officer, the Committees rely to a large extent upon the recommendations of the
Chief Executive Officer. Because the Committees believe that employment
opportunities for executive officers are not necessarily limited to or
coextensive with the financial institutions included in the Keefe, Bruyette &
Woods New England Bank Index shown in the performance graph below, its review of
compensation information includes companies not included in this industry index.
Bonuses and option grants are intended to provide annual and long-term
compensation incentives. Bonuses and option grants are awarded to executive
officers based mainly on the financial performance of Bancorp and the Bank
compared to targets for the business segment for which each executive is
responsible. Bonuses were paid after the Committees reviewed the financial
performance of the Bank for 1997. Stock option grants are intended to create
incentives for the long-term growth and financial success of Bancorp and the
Bank and to increase the commonality of interest between management and
Bancorp's shareholders and are granted as and when determined appropriate by the
Committees. The level of bonuses and stock options awarded to individuals is not
based on any formula; instead, a general determination is made based on the
above factors and, in the case of executive officers other than the Chief
Executive Officer, the recommendations of the Chief Executive Officer. Stock
option awards during 1997 reflect the Committees' review of the Bank's financial
performance.

         The salary and perquisites paid to the Chief Executive Officer in 1997
are specified in a 1995 employment agreement between the Chief Executive Officer
and Bancorp and the Bank (see Executive Compensation (Salary and Bonus Payments,
Options Granted and Other) - Employment Agreement - George W. Phillips, below).
Effective July 1, 1995, as part of the employment agreement, the Committee
established a supplemental retirement benefit arrangement for Mr. Phillips,
including the purchase of a split-dollar life insurance policy, in recognition
of the improved financial performance of the Bank. Also, as part of the
employment agreement, Mr. Phillips did not participate in any allocation of
stock options and was not eligible for any year-end bonus compensation payments
except for discretionary payments to the Bank's 401(k) Plan in which all Plan
members participate.

SEVERANCE ARRANGEMENTS

         EMPLOYMENT AGREEMENT - JOHN R. PUTNEY. The employment agreement between
John R. Putney and the Bank described above, provides that upon a "non-hostile
change of control" the term of the employment agreement shall automatically
convert to a term of three years from the date of the "change of control" and
automatically extend for an additional one-year period on each anniversary.
"Non-hostile change of control" is defined in the agreement and generally refers
to a 25 percent or more change in ownership of the Common Stock of Bancorp which
is consented to by a two-thirds vote of the directors of Bancorp.

         SPECIAL TERMINATION AGREEMENTS. Bancorp and the Bank have entered into
severance agreements with Leo C. Donahue, Paul M. Peduto, John R. Putney and
Mark J. Terry. Each severance agreement provides severance pay benefits to the
relevant officer if his employment is terminated under certain circumstances
following a "change of control." "Change of control" is defined in each
agreement and generally refers to a 25 percent or more change in ownership of
the Common Stock of Bancorp or the Bank which, in some cases, is not consented
to by the Board of Directors. If there is such a "change of control" at any time
during the term of the agreement, and thereafter the officer's employment were
terminated either by Bancorp or the Bank other than for "cause" or by the
officer following the officer's demotion, the officer's loss of title or office,
or a reduction in the officer's annual compensation, the officer would generally
be entitled to receive a lump sum cash payment equal to approximately three
times his average annual compensation over his five most recent years of
employment with Bancorp or the Bank. The agreements terminate upon the earliest
of termination of the officer's employment by Bancorp and the Bank for cause,
the officer's resignation or termination for any reason prior to a change in
control, or resignation after a change in control except for reasons just
described.

         STOCK OPTION AGREEMENTS. Stock option agreements with Leo C. Donahue,
Paul M. Peduto, John R. Putney and Mark J. Terry provide that currently
exercisable stock options shall immediately vest in full and become exercisable
upon a "change of control," as defined in such stock option agreements.

                                   PROPOSAL 2

                               PROPOSAL TO APPROVE
                1998 INCENTIVE AND NONQUALIFIED STOCK OPTION PLAN


PROPOSAL

         The Board of Directors has adopted the 1998 Incentive and Nonqualified
Stock Option Plan (the "1998 Plan") for Directors, officers, employees and other
key persons of the Corporation and its subsidiaries, subject to the approval of
the 1998 Plan by the stockholders.

         The 1998 Plan will be administered by the Executive Committee (the
"Committee") of the Board of Directors. The Committee, at its discretion, may
grant incentive and nonqualified stock options to purchase shares of the Common
Stock of the Corporation. These awards are described in greater detail below.

         Subject to adjustment for stock splits, stock dividends and similar
events, the total number of shares of Common Stock that can be issued under the
1998 Plan is 300,000 shares. Based solely upon the closing price of the Common
Stock as reported by the NASDAQ National Market on March 2, 1998, the maximum
aggregate market value of the securities to be issued under the 1998 Plan would
be $6.9 million. In order to satisfy the performance-based compensation
exception to the $1 million cap on the Corporation's tax deduction imposed by
Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"),
the 1998 Plan also provides that stock options with respect to no more than
100,000 shares of Common Stock may be granted to any one individual in any
calendar year. The shares issued by the Corporation under the 1998 Plan may be
authorized but unissued shares, or shares reacquired by the Corporation. To the
extent that awards under the 1998 Plan do not vest or otherwise revert to the
Corporation, the shares of Common Stock represented by such awards may be the
subject of subsequent awards.

RECOMMENDATION

         The Board of Directors believes that stock option awards can play an
important role in the success of the Corporation by encouraging and enabling the
officers and other employees of the Corporation and its subsidiaries upon whose
judgment, initiative and efforts the Corporation largely depends for the
successful conduct of its business to acquire a proprietary interest in the
Corporation. The Board of Directors anticipates that providing such persons with
a direct stake in the Corporation will assure a closer identification of the
interests of participants in the 1998 Plan with those of the Corporation,
thereby stimulating their efforts on the Corporation's behalf and strengthening
their desire to remain with the Corporation. However, under the Corporation's
1991 and 1995 Incentive and Nonqualified Stock Option Plans (collectively, the
"Existing Plans"), there are only a total of 59,000 shares remaining available
for grant.

         The Board of Directors believes that the proposed 1998 Plan, which
provides for stock options on substantially the same terms as the Existing
Plans, will help the Corporation to achieve its goals by keeping the
Corporation's incentive compensation program dynamic and competitive with those
of other companies. Accordingly, the Board of Directors believes that the 1998
Plan is in the best interests of the Corporation and its stockholders and
recommends that the stockholders approve the 1998 Plan.


                                       20
   22
         THE BOARD OF DIRECTORS RECOMMENDS THAT THE 1998 PLAN BE APPROVED, AND
THEREFORE RECOMMENDS A VOTE FOR THIS PROPOSAL.

SUMMARY OF THE 1998 PLAN

         The following description of certain features of the 1998 Plan is
intended to be a summary only. The summary is qualified in its entirety by the
full text of the 1998 Plan which is attached hereto as Exhibit A.

         Plan Administration; Eligibility. The 1998 Plan is administered by the
Committee. All members of the Committee must be "non-employee directors" as that
term is defined under the rules promulgated by the Securities and Exchange
Commission and "outside directors" as that term is defined in Section 162 of the
Code and the regulations promulgated thereunder.

         The Committee has full power to select, from among the employees
eligible for awards, the individuals to whom awards will be granted, to make any
combination of awards to participants, and to determine the specific terms and
conditions of each award, subject to the provisions of the 1998 Plan. The
Committee may permit Common Stock, and other amounts payable pursuant to stock
options, to be deferred. In such instances, the Committee may permit interest,
dividend or deemed dividends to be credited to the amount of deferrals.

         Persons eligible to participate in the 1998 Plan will be those
employees and other key persons of the Corporation and its subsidiaries who are
responsible for or contribute to the management, growth or profitability of the
Corporation and its subsidiaries, as selected from time to time by the
Committee. Directors of the Corporation who are not employed by the Corporation
or its subsidiaries ("Independent Directors") will also be eligible for certain
awards under the 1998 Plan.

         Stock Options. The 1998 Plan permits the granting of (i) options to
purchase Common Stock intended to qualify as incentive stock options ("Incentive
Options") under Section 422 of the Code and (ii) options that do not so qualify
("Nonqualified Options"). The option exercise price of each option will be
determined by the Committee but may not be less than 100% of the fair market
value of the Common Stock on the date of grant.

         The term of each option will be fixed by the Committee and may not
exceed ten years from date of grant in the case of an Incentive Option. The
Committee will determine at what time or times each option may be exercised and,
subject to the provisions of the 1998 Plan, the period of time, if any, after
retirement, death, disability or termination of employment during which options
may be exercised. Options may be made exercisable in installments, and the
exercisability of options may be accelerated by the Committee.

         Upon exercise of options, the option exercise price must be paid in
full either in cash or by certified or bank check or other instrument acceptable
to the Committee or, if the Committee so permits, by delivery of shares of
Common Stock already owned by the optionee. The exercise price may also be
delivered to the Corporation by a broker pursuant to irrevocable instructions to
the broker from the optionee.

         To qualify as Incentive Options, options must meet additional Federal
tax requirements, including limits on the value of shares subject to Incentive
Options which first become exercisable in any one calendar year, and a shorter
term and higher minimum exercise price in the case of certain large
stockholders.

         The 1998 Plan provides for the grant of Nonqualified Options to
Independent Directors in the discretion of the Committee. The exercise price of
each such Nonqualified Option is the fair market value of the Common Stock on
the date of grant.


                                       21
   23
         Adjustments for Stock Dividends, Mergers, Etc. The Committee will make
appropriate adjustments in outstanding awards to reflect stock dividends, stock
splits and similar events. In the event of a merger, liquidation, sale of the
Corporation or similar event, the Committee, in its discretion, may provide for
substitution or adjustments of outstanding options, or may terminate all
unvested options with or without payment of cash consideration.

         Amendments and Termination. The Board of Directors may at any time
amend or discontinue the 1998 Plan and the Committee may at any time amend or
cancel outstanding awards for the purpose of satisfying changes in the law or
for any other lawful purpose. However, no such action may be taken which
adversely affects any rights under outstanding awards without the holder's
consent. In addition, the Committee may amend any outstanding Stock Option to
reduce the exercise price in order to fulfill a legitimate corporate purpose
(e.g., to retain a key employee) or to maintain the value of such outstanding
Stock Option under circumstances beyond the control of the Corporation's
management, but in no event shall such amendments be made to outstanding Stock
Options representing greater than 10% of the total number of shares of Stock
authorized for issuance pursuant to the Plan. Further, Plan amendments shall be
subject to approval by the Corporation's stockholders if and to the extent
required by the Code to preserve the qualified status of Incentive Options or to
ensure that compensation under the Plan qualifies as performance-based under
Section 162(m) of the Code.

         Change of Control Provisions. The 1998 Plan provides that in the event
of a "Change of Control" (as defined in the 1998 Plan) of the Corporation, all
stock options shall automatically become fully exercisable. In addition, at any
time prior to or after a Change of Control, the Committee may accelerate awards
and waive conditions and restrictions on any awards to the extent it may
determine appropriate.

EFFECTIVE DATE OF 1998 PLAN

         The 1998 Plan will become effective upon the affirmative vote of the
holders of at least a majority of the shares of Common Stock present or
represented and voting on the proposal at the Annual Meeting. For purposes of
the vote on the 1998 Plan, abstentions and broker non-votes will have no effect
on the results of the vote. Both abstentions and broker non-votes will count
towards the presence of a quorum. Awards of Incentive Stock Options may be
granted under the 1998 Plan until May 6, 2008.

NEW PLAN BENEFITS

         Approximately 165 employees and Independent Directors are currently
eligible to participate in the 1998 Plan. The number of shares that may be
granted to executive officers, non-executive officers and directors is
undeterminable at this time, as such grants are subject to the discretion of the
Committee.

TAX ASPECTS UNDER THE U.S. INTERNAL REVENUE CODE

         The following is a summary of the principal Federal income tax
consequences of option grants under the 1998 Plan. It does not describe all
Federal tax consequences under the 1998 Plan, nor does it describe state or
local tax consequences.


                                       22
   24
         Incentive Options. Under the Code, an employee will not realize taxable
income by reason of the grant or the exercise of an Incentive Option. If an
employee exercises an Incentive Option and does not dispose of the shares until
the later of (a) two years from the date the option was granted or (b) one year
from the date the shares were transferred to the employee, the entire gain, if
any, realized upon disposition of such shares will be taxable to the employee as
long-term or mid-term capital gain (depending on the holding period of the
shares), and the Corporation will not be entitled to any deduction. The exercise
of an Incentive Option will give rise to an item of tax preference that may
result in alternative minimum tax liability for the employee.

         If an employee disposes of the shares within such one-year or two-year
period in a manner so as to violate the holding period requirements (a
"disqualifying disposition"), the employee generally will realize ordinary
income in the year of disposition, and, provided the Corporation complies with
applicable withholding requirements, the Corporation will receive a
corresponding deduction, in an amount equal to the excess of (1) the lesser of
(x) the amount, if any, realized on the disposition and (y) the fair market
value of the shares on the date the option was exercised over (2) the option
price. Any additional gain realized by the employee on the disposition of the
shares acquired upon exercise of the option will be long-term, mid-term or
short-term capital gain and any loss will be long-term, mid-term or short-term
capital loss depending upon the holding period for such shares.

         The employee will be considered to have disposed of his shares if he
sells, exchanges, makes a gift of or transfers legal title to the shares (except
by pledge or by transfer on death). If the disposition of shares is by gift and
violates the holding period requirements, the amount of the employee's ordinary
income (and the Corporation's deduction) is equal to the fair market value of
the shares on the date of exercise less the option price. If the disposition is
by sale or exchange, the employee's tax basis will equal the amount paid for the
shares plus any ordinary income realized as a result of the disqualifying
distribution.

         An employee who surrenders shares of Common Stock in payment of the
exercise price of his Incentive Option generally will not, under proposed
Treasury Regulations, recognize gain or loss on his surrender of such shares.
The surrender of shares previously acquired upon exercise of an Incentive Option
in payment of the exercise price of another Incentive Option is, however, a
"disposition" of such stock. If the incentive stock option holding period
requirements described above have not been satisfied with respect to such stock,
such disposition will be a disqualifying disposition that may cause the employee
to recognize ordinary income as discussed above.

         All of the shares received by an employee upon exercise of an Incentive
Option by surrendering shares of Common Stock will be subject to the incentive
stock option holding period requirements. Of those shares, a number of shares
(the "Exchange Shares") equal to the number of shares of Common Stock
surrendered by the employee will have the same tax basis for capital gains
purposes (increased by any ordinary income recognized as a result of any
disqualifying disposition of the surrendered shares if they were Incentive
Option shares) and the same capital gains holding period as the shares
surrendered. For purposes of determining ordinary income upon a subsequent
disqualifying disposition of the Exchange Shares, the amount paid for such
shares will be deemed to be the fair market value of the shares surrendered. The
balance of the shares received by the employee will have a tax basis (and a
deemed purchase price) of zero and a capital gains holding period beginning on
the date of exercise. The incentive stock option holding period for all shares
will be the same as if the option had been exercised for cash.

         An Incentive Option that is exercised by an employee more than three
months after an employee's employment terminates will be treated as a
Nonqualified Option for Federal income tax purposes. In the case of an employee
who is disabled, the three-month period is extended to one year and in the case
of an employee who dies, the three-month employment rule does not apply.


                                       23
   25
         Nonqualified Options. There are no Federal income tax consequences to
either the optionee, or the Corporation on the grant of a Nonqualified Option.
On the exercise of a Nonqualified Option, the optionee has taxable ordinary
income equal to the excess of the fair market value of the shares of Common
Stock received on the exercise date over the option price of the shares. The
optionee's tax basis for the shares acquired upon exercise of a Nonqualified
Option is increased by the amount of such taxable income. The Corporation will
be entitled to a Federal income tax deduction in an amount equal to the ordinary
income recognized by the optionee. Upon the sale of the shares acquired by
exercise of a Nonqualified Option, optionees will realize long-term, mid-term or
short-term capital gain or loss depending upon his or her holding period for
such shares.

         An optionee who surrenders shares of Common Stock in payment of the
exercise price of a Nonqualified Option will not recognize gain or loss on his
surrender of such shares. (Such an optionee will recognize ordinary income on
the exercise of the Nonqualified Option as described above.) Of the shares
received in such an exchange, that number of shares equal to the number of
shares surrendered will have the same tax basis and capital gains holding period
as the shares surrendered. The balance of the shares received will have a tax
basis equal to their fair market value on the date of exercise, and the capital
gains holding period will begin on the date of exercise.

         Parachute Payments. The exercise of any portion of any option that is
accelerated due to the occurrence of a change of control may cause a portion of
the payments with respect to such accelerated options to be treated as
"parachute payments" as defined in the Code. Any such parachute payments may be
non-deductible to the Corporation, in whole or in part, and may subject the
recipient to a non-deductible 20% Federal excise tax on all or portion of such
payment (in addition to other taxes ordinarily payable).

LIMITATION ON COMPANY'S DEDUCTIONS

         As a result of Section 162(m) of the Code, the Corporation's Federal
tax deduction for certain awards under the Plan may be limited to the extent
that the Chief Executive Officer or other executive officer whose compensation
is required to be reported in the summary compensation table receives
compensation (other than performance-based compensation) in excess of $1 million
a year.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS


         The Bank makes and has made loans to certain of its officers and
Directors and their associates. All of such loans were made in the ordinary
course of business and were made on substantially the same terms, including
interest rates and collateral, as those prevailing at the time for comparable
transactions with other persons. Management believes that such loans did not
involve more than the normal risk of collectibility or present other unfavorable
features.

         Certain loans or other extensions of credit to principal officers and
Directors must be approved by the Bank's Loan Committee and the Board of
Directors, and reported annually to the Massachusetts Commissioner of Banks. In
addition, the Bank is subject to regulations of the Federal Deposit Insurance
Corporation which (i) require that such loans to principal officers be made on
the same rates, terms and conditions as loans to unaffiliated persons, and (ii)
impose reporting requirements, approval procedures and limits on the amounts of
such loans. As a matter of policy, the Bank also makes certain loans to other
employees.

         The Bank engages John's Janitorial Services (JJS Services), of which
Bancorp Director John H. Womack is President, to perform janitorial work at its
six offices. Fees paid in 1997 to JJS Services were approximately $48,000.

                         INDEPENDENT PUBLIC ACCOUNTANTS


         The firm of Arthur Andersen LLP has served as Bancorp's independent
public accountants since 1997. Representatives of Arthur Andersen LLP have
accepted an invitation to attend the Annual Meeting. They will have an
opportunity to make a statement should they so desire and will be available to
respond to appropriate questions.


                                  OTHER MATTERS

         The cost of soliciting proxies will be paid by Bancorp. In addition to
solicitation by mail, officers and employees of the Bank, who will receive no
compensation for their services other than their salaries, may solicit proxies
by telephone, telegraph or personal interview. Brokerage houses, nominees,
fiduciaries and other custodians are requested to forward soliciting material to
the beneficial owners of shares held of record by them and will be reimbursed
for their expenses. Bancorp also intends to employ the services of D.F. King &
Co., Inc. to solicit proxies. It is estimated that D.F. King & Co., Inc. will
receive approximately $3,000 plus reimbursement of certain out-of-pocket
expenses for its services in connection with such solicitation of proxies.

         It is not anticipated that matters other than those set forth in the
Notice of Annual Meeting and described in this Proxy Statement will be brought
before the Annual Meeting, but if any such matters are properly presented, the
persons named in the proxy will vote in accordance with their best judgment.


                              STOCKHOLDER PROPOSALS

         Proposals of stockholders of Bancorp intended to be presented at the
1999 annual meeting of Bancorp's stockholders must be received by Bancorp not
later than November 27, 1998, to be included in Bancorp's proxy statement and
form of proxy relating to that annual meeting. If the date of the 1999 annual
meeting is subsequently changed by more than 30 calendar days from the date of
this year's annual meeting, Bancorp will, in a timely manner, inform its
stockholders of such change and the date by which proposals of stockholders must
be received. Nominations and proposals of stockholders may be submitted to
Bancorp for consideration at the 1999 Annual Meeting if certain conditions set
forth in Bancorp's By-Laws are satisfied, although such nominations and
proposals will not be included in the proxy statement and form of proxy relating
to that meeting unless submitted in accordance with the time limits set forth
above and related rules of the Securities and Exchange Commission. See "Election
Of a Class of Directors - The Board of Directors and its Committees - Nominating
Committee."

         acts and proceedings as it shall deem advisable; to interpret the terms
         and provisions of the Plan and any Stock Option (including related
         written instruments); to make all determinations it deems advisable for
         the administration of the Plan; to decide all disputes arising in
         connection with the Plan; and to otherwise supervise the administration
         of the Plan.

         All decisions and interpretations of the Administrator shall be binding
on all persons, including the Corporation and Plan participants.


SECTION 3.        STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION

         (a) Stock Issuable. The maximum number of shares of Stock reserved and
available for issuance under the Plan shall be 300,000 shares. For purposes of
this limitation, the shares of Stock underlying any Stock Options which are
forfeited, canceled, reacquired by the Corporation, satisfied without the
issuance of Stock or otherwise terminated (other than by exercise) shall be
added back to the shares of Stock available for issuance under the Plan. Subject
to such overall limitation, shares of Stock may be issued up to such maximum
number pursuant to any Stock Options; provided, however, that Stock Options with
respect to no more than 100,000 shares of stock may be granted to any one
individual participant during any calendar year period. The shares available for
issuance under the Plan may be authorized but unissued shares of Stock or shares
of Stock reacquired by the Corporation and held in its treasury.

         (b) Changes in Stock. If, as a result of any reorganization,
recapitalization, reclassification, stock dividend, stock split, reverse stock
split or other similar change in the Corporation's capital stock, the
outstanding shares of Stock are increased or decreased or are exchanged for a
different number or kind of shares or other securities of the Corporation, or
additional shares or new or different shares or other securities of the
Corporation or other non-cash assets are distributed with respect to such shares
of Stock or other securities, the Administrator shall make an appropriate or
proportionate adjustment in (i) the maximum number of shares reserved for
issuance under the Plan, (ii) the number of Stock Options that can be granted to
any one individual participant, (iii) the number and kind of shares or other
securities subject to any then outstanding Stock Options under the Plan, and
(iv) the price for each share subject to any then outstanding Stock Options
under the Plan, without changing the aggregate exercise price (i.e., the
exercise price multiplied by the number of Stock Options as to which such Stock
Options remain exercisable). The adjustment by the Administrator shall be final,
binding and conclusive. No fractional shares of Stock shall be issued under the
Plan resulting from any such adjustment, but the Administrator in its discretion
may make a cash payment in lieu of fractional shares.

         The Administrator may also adjust the number of shares subject to
outstanding Stock Options and the exercise price and the terms of outstanding
Stock Options to take into consideration material changes in accounting
practices or principles, extraordinary dividends, acquisitions or dispositions
of stock or property or any other event if it is determined by the Administrator
that such adjustment is appropriate to avoid distortion in the operation of the
Plan, provided that no such adjustment shall be made in the case of an Incentive
Stock Option, without the consent of the participant, if it would constitute a
modification, extension or renewal of the Option within the meaning of Section
424(h) of the Code.

         (c) Mergers. In contemplation of and subject to the consummation of a
consolidation or merger or sale of all or substantially all of the assets of the
Corporation in which outstanding shares of Stock are exchanged for securities,
cash or other property of an unrelated corporation or business entity or in the
event of a liquidation of the Corporation (in each case, a "Transaction"), the
Board, or the board of directors of any corporation assuming the obligations of
the Corporation, may, in its


                                       A-3
   31
discretion, take any one or more of the following actions, as to outstanding
Stock Options: (i) provide that such Stock Options shall be assumed or
equivalent awards shall be substituted, by the acquiring or succeeding
corporation (or an affiliate thereof), and/or (ii) upon written notice to the
participants, provide that all Stock Options will terminate immediately prior
to the consummation of the Transaction. In the event that, pursuant to clause
(ii) above, Stock Options will terminate immediately prior to the consummation
of the Transaction, all vested Stock Options, shall be fully settled, in cash
or in kind, in an amount equal to the difference between (A) the Merger Price
times the number of shares of Stock subject to such outstanding Stock Options
and (to the extent then exercisable at prices not in excess of the Merger
Price) and (B) the aggregate exercise price of all such outstanding Stock
Options; provided, however, that each participant shall be permitted, within a
specified period determined by the Administrator prior to the consummation of
the Transaction, to exercise all outstanding Stock Options and, including those
that are not then exercisable, subject to the consummation of the Transaction.

         (d) Substitute Stock Options. The Administrator may grant Stock Options
under the Plan in substitution for stock and stock based awards held by
employees of another corporation who become employees of the Corporation or a
Subsidiary as the result of a merger or consolidation of the employing
corporation with the Corporation or a subsidiary or the acquisition by the
Corporation or a Subsidiary of property or stock of the employing corporation.
The Administrator may direct that the substitute awards be granted on such terms
and conditions as the Administrator considers appropriate in the circumstances.


SECTION 4.        ELIGIBILITY

         Participants in the Plan will be such full or part-time officers and
other employees, Independent Directors and key persons of the Corporation and
its Subsidiaries who are responsible for or contribute to the management, growth
or profitability of the Corporation and its Subsidiaries as are selected from
time to time by the Administrator in its sole discretion.


SECTION 5.        STOCK OPTIONS

         Any Stock Option granted under the Plan shall be in such form as the
Administrator may from time to time approve.

         Stock Options granted under the Plan may be either Incentive Stock
Options or Non-Qualified Stock Options. Incentive Stock Options may be granted
only to employees of the Corporation or any Subsidiary that is a "subsidiary
corporation" within the meaning of Section 424(f) of the Code. To the extent
that any Option does not qualify as an Incentive Stock Option, it shall be
deemed a Non-Qualified Stock Option.

         No Incentive Stock Option shall be granted under the Plan after May 6,
2008.

         (a) Stock Options Granted to Employees and Key Persons. The
Administrator in its discretion may grant Stock Options to eligible employees
and key persons of the Corporation or any Subsidiary. Stock Options granted
pursuant to this Section 5(a) shall be subject to the following terms and
conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of the Plan, as the Administrator shall deem
desirable. If the Administrator so determines, Stock Options may be granted in
lieu of cash compensation at the participant's election, subject to


                                       A-4
   32
such terms and conditions as the Administrator may establish, as well as in
addition to other compensation.

                  (i) Exercise Price. The exercise price per share for the Stock
         covered by a Stock Option granted pursuant to this Section 5(a) shall
         be determined by the Administrator at the time of grant but shall not
         be less than 100% of the Fair Market Value on the date of grant. If an
         employee owns or is deemed to own (by reason of the attribution rules
         of Section 424(d) of the Code) more than 10% of the combined voting
         power of all classes of stock of the Corporation or any parent or
         subsidiary corporation and an Incentive Stock Option is granted to such
         employee, the option price of such Incentive Stock Option shall be not
         less than 110% of the Fair Market Value on the grant date.

                  (ii) Option Term. The term of each Stock Option shall be fixed
         by the Administrator, but no Incentive Stock Option shall be
         exercisable more than ten years after the date the option is granted.
         If an employee owns or is deemed to own (by reason of the attribution
         rules of Section 424(d) of the Code) more than 10% of the combined
         voting power of all classes of stock of the Corporation or any parent
         or subsidiary corporation and an Incentive Stock Option is granted to
         such employee, the term of such option shall be no more than five years
         from the date of grant.

                  (iii) Exercisability; Rights of a Stockholder. Stock Options
         shall become exercisable at such time or times, whether or not in
         installments, as shall be determined by the Administrator at or after
         the grant date; provided, however, that Stock Options granted in lieu
         of compensation shall be exercisable in full as of the grant date. The
         Administrator may at any time accelerate the exercisability of all or
         any portion of any Stock Option. An optionee shall have the rights of a
         stockholder only as to shares acquired upon the exercise of a Stock
         Option and not as to unexercised Stock Options.

                  (iv) Method of Exercise. Stock Options may be exercised in
         whole or in part by giving written notice of exercise to the
         Corporation, specifying the number of shares to be purchased. Payment
         of the purchase price may be made by one or more of the following
         methods to the extent provided in the Option agreement:

                           (A) In cash, by certified or bank check or other
                  instrument acceptable to the Administrator;

                           (B) Through the delivery (or attestation to the
                  ownership) of shares of Stock that have been purchased by the
                  optionee on the open market or that are not then subject to
                  restrictions under any Corporation plan and that have been
                  beneficially owned by the optionee for at least six months, if
                  permitted by the Administrator in its discretion. Such
                  surrendered shares shall be valued at Fair Market Value on the
                  exercise date; or

                           (C) By the optionee delivering to the Corporation a
                  properly executed exercise notice together with irrevocable
                  instructions to a broker to promptly deliver to the
                  Corporation cash or a check payable and acceptable to the
                  Corporation for the purchase price; provided that in the event
                  the optionee chooses to pay the purchase price as so provided,
                  the optionee and the broker shall comply with such procedures
                  and enter into such agreements of indemnity and other
                  agreements as the Administrator shall prescribe as a condition
                  of such payment procedure.

         Payment instruments will be received subject to collection. The
         delivery of certificates representing the shares of Stock to be
         purchased pursuant to the exercise of a Stock Option


                                       A-5
   33
         will be contingent upon receipt from the optionee (or a purchaser
         acting in his stead in accordance with the provisions of the Stock
         Option) by the Corporation of the full purchase price for such shares
         and the fulfillment of any other requirements contained in the Stock
         Option or applicable provisions of laws. In the event an optionee
         chooses to pay the purchase price by previously-owned shares of Stock
         through the attestation method, the shares of Stock transferred to the
         optionee upon the exercise of the Stock Option shall be net of the
         number of shares attested to.

                  (v) Annual Limit on Incentive Stock Options. To the extent
         required for "incentive stock option" treatment under Section 422 of
         the Code, the aggregate Fair Market Value (determined as of the time of
         grant) of the shares of Stock with respect to which Incentive Stock
         Options granted under this Plan and any other plan of the Corporation
         or its parent and subsidiary corporations become exercisable for the
         first time by any optionee during any calendar year shall not exceed
         $100,000. To the extent that any Stock Option exceeds this limit, it
         shall constitute a Non-Qualified Stock Option.

         (b)      Stock Options Granted to Independent Directors.

                  (i) Grant of Options.

                           (A) The Administrator, in its discretion, may grant
                  Non-Qualified Stock Options to Independent Directors. Any such
                  grant may vary among individual Independent Directors.

                           (B) The exercise price per share for the Stock
                  covered by a Stock Option granted under this Section 5(b)
                  shall be equal to the Fair Market Value of the Stock on the
                  date the Stock Option is granted.

                  (ii) Exercise; Termination.

                           (A) An Option issued under this Section 5(b) shall
                  not be exercisable after the expiration of ten years from the
                  date of grant.

                           (B) Options granted under this Section 5(b) may be
                  exercised only by written notice to the Corporation specifying
                  the number of shares to be purchased. Payment of the full
                  purchase price of the shares to be purchased may be made by
                  one or more of the methods specified in Section 5(a)(iv). An
                  optionee shall have the rights of a stockholder only as to
                  shares acquired upon the exercise of a Stock Option and not as
                  to unexercised Stock Options.

         (c) Non-transferability of Options. No Stock Options shall be
transferable by the optionee otherwise than by will or by the laws of descent
and distribution and all Stock Options shall be exercisable, during the
optionee's lifetime, only by the optionee. Notwithstanding the foregoing, the
Administrator, in its sole discretion, may provide in the Stock Option agreement
regarding a given Option that the optionee may transfer, without consideration
for the transfer, his Non-Qualified Stock Options to members of his immediate
family, to trusts for the benefit of such family members, or to partnerships in
which such family members are the only partners, provided that the transferee
agrees in writing with the Corporation to be bound by all of the terms and
conditions of this Plan and the applicable Option.


                                       A-6
   34
         (d) Termination. Except as may otherwise be provided below in this
Section 5(d) or by the Administrator either in the Stock Option Agreement or
subject to Section 10 below, in writing after the Stock Option agreement is
issued, an optionee's rights in all Stock Options shall automatically terminate
upon the participant's termination of employment (or cessation of business
relationship) with the Corporation and its Subsidiaries for any reason, in
accordance with the following provisions:

                  (i) if the optionee's employment shall have been terminated by
         the Corporation or a subsidiary, at any time, involuntarily for cause,
         the option shall immediately terminate and may no longer be exercised;
         and

                  (ii) if the optionee's employment by the Corporation and its
         subsidiaries shall have been terminated for any reason other than for
         cause, the optionee may, at any time within a period of two (2) years
         after such termination of employment, exercise the option to the extent
         that it was exercisable on the date of termination of the optionee's
         employment, provided, however that no option may be exercised to any
         extent by anyone after the date of expiration of the option.

                  Each Director option shall, to the extent it was exercisable
         on the date on which the director ceases to perform services for
         Bancorp or a subsidiary, terminate on the date two (2) years after such
         date.

                  Notwithstanding the above, however, no option may be exercised
         to any extent by anyone after the date of expiration of the option.


SECTION 6.  TAX WITHHOLDING

         (a) Payment by Participant. Each participant shall, no later than the
date as of which the value of a Stock Option or of any Stock or other amounts
received thereunder first becomes includable in the gross income of the
participant for Federal income tax purposes, pay to the Corporation, or make
arrangements satisfactory to the Administrator regarding payment of, any
Federal, state, or local taxes of any kind required by law to be withheld with
respect to such income. The Corporation and its Subsidiaries shall, to the
extent permitted by law, have the right to deduct any such taxes from any
payment of any kind otherwise due to the participant. The Corporation's
obligation to deliver stock certificates to any participant is subject to and
conditioned on tax obligations being satisfied by the participant.

         (b) Payment in Stock. Subject to approval by the Administrator, a
participant may elect to have such tax withholding obligation satisfied, in
whole or in part, by (i) authorizing the Corporation to withhold from shares of
Stock to be issued pursuant to any Stock Option a number of shares with an
aggregate Fair Market Value (as of the date the withholding is effected) that
would satisfy the withholding amount due, or (ii) transferring to the
Corporation shares of Stock owned by the participant with an aggregate Fair
Market Value (as of the date the withholding is effected) that would satisfy the
withholding amount due.


SECTION 7.  TRANSFER, LEAVE OF ABSENCE, ETC.

         For purposes of the Plan, the following events shall not be deemed a
termination of employment:


                                       A-7
   35
         (a) a transfer to the employment of the Corporation from a Subsidiary
or from the Corporation to a Subsidiary, or from one Subsidiary to another; or

         (b) an approved leave of absence for military service or sickness, or
for any other purpose approved by the Corporation, if the employee's right to
re-employment is guaranteed either by a statute or by contract or under the
policy pursuant to which the leave of absence was granted or if the
Administrator otherwise so provides in writing.


SECTION 8.  AMENDMENTS AND TERMINATION

         The Board may, at any time, amend or discontinue the Plan and the
Administrator may, at any time, amend or cancel any outstanding Stock Option for
the purpose of satisfying changes in law or for any other lawful purpose, but no
such action shall adversely affect rights under any outstanding Stock Option
without the holder's consent. In addition the Administrator may amend any
outstanding Stock Option to reduce the exercise price in order to fulfill a
legitimate corporate purpose (e.g., to retain a key employee) or to maintain the
value of such outstanding Stock Option under circumstances beyond the control of
the Corporation's management, but in no event shall such amendments be made to
outstanding Stock Options representing greater than 10% of the total number of
shares of Stock authorized for issuance pursuant to the Plan. If and to the
extent determined by the Administrator to be required by the Code to ensure that
Incentive Stock Options granted under the Plan are qualified under Section 422
of the Code or to ensure that compensation earned under Stock Options qualifies
as performance-based compensation under Section 162(m) of the Code, if and to
the extent intended to so qualify, Plan amendments shall be subject to approval
by the Corporation stockholders entitled to vote at a meeting of stockholders.
Nothing in this Section 8 shall limit the Board's authority to take any action
permitted pursuant to Section 3(c).


SECTION 9.  STATUS OF PLAN

         With respect to the portion of any Stock Option that has not been
exercised and any payments in cash, Stock or other consideration not received by
a participant, a participant shall have no rights greater than those of a
general creditor of the Corporation unless the Administrator shall otherwise
expressly determine in connection with any Stock Option or Stock Options.


SECTION 10.  CHANGE OF CONTROL PROVISIONS

         Upon the occurrence of a Change of Control as defined in this Section
10:

         (a) Except as otherwise provided in the applicable Stock Option
agreement, each outstanding Stock Option shall automatically become fully
exercisable.

         (b) "Change of Control" shall mean the occurrence of any one of the
following events:

                  (i) any "person," as such term is used in Sections 13(d) and
         14(d) of the Act (other than the Corporation, any of its Subsidiaries,
         or any trustee, fiduciary or other person or entity holding securities
         under any employee benefit plan or trust of the Corporation or any of
         its Subsidiaries), together with all "affiliates" and "associates" (as
         such terms are defined in Rule 12b-2 under the Act) of such person,
         shall become the "beneficial owner" (as such term is defined in Rule
         13d-3 under the Act), directly or indirectly, of securities of the
         Corporation representing 25% or more of the combined voting power of
         the Corporation's then outstanding


                                       A-8
   36
         securities having the right to vote in an election of the Corporation's
         Board of Directors ("Voting Securities") (in such case other than as a
         result of an acquisition of securities directly from the Corporation);
         or

                  (ii) persons who, as of the Effective Date, constitute the
         Corporation's Board of Directors (the "Incumbent Directors") cease for
         any reason, including, without limitation, as a result of a tender
         offer, proxy contest, merger or similar transaction, to constitute at
         least a majority of the Board, provided that any person becoming a
         director of the Corporation subsequent to the Effective Date shall be
         considered an Incumbent Director if such person's election was approved
         by or such person was nominated for election by either (A) a vote of at
         least a majority of the Incumbent Directors or (B) a vote of at least a
         majority of the Incumbent Directors who are members of a nominating
         committee comprised, in the majority, of Incumbent Directors; or

                  (iii) the stockholders of the Corporation shall approve (A)
         any consolidation or merger of the Corporation where the stockholders
         of the Corporation, immediately prior to the consolidation or merger,
         would not, immediately after the consolidation or merger, beneficially
         own (as such term is defined in Rule 13d-3 under the Act), directly or
         indirectly, shares representing in the aggregate 50% or more of the
         voting shares of the corporation issuing cash or securities in the
         consolidation or merger (or of its ultimate parent corporation, if
         any), (B) any sale, lease, exchange or other transfer (in one
         transaction or a series of transactions contemplated or arranged by any
         party as a single plan) of all or substantially all of the assets of
         the Corporation or (C) any plan or proposal for the liquidation or
         dissolution of the Corporation.

         Notwithstanding the foregoing, a "Change of Control" shall not be
deemed to have occurred for purposes of the foregoing clause (i) solely as the
result of an acquisition of securities by the Corporation which, by reducing the
number of shares of Voting Securities outstanding, increases the proportionate
number of shares of Voting Securities beneficially owned by any person to 25% or
more of the combined voting power of all then outstanding Voting Securities;
provided, however, that if any person referred to in this sentence shall
thereafter become the beneficial owner of any additional shares of Voting
Securities (other than pursuant to a stock split, stock dividend, or similar
transaction or as a result of an acquisition of securities directly from the
Corporation), then a "Change of Control" shall be deemed to have occurred for
purposes of the foregoing clause (i).


SECTION 11.  GENERAL PROVISIONS

         (a) No Distribution; Compliance with Legal Requirements. The
Administrator may require each person acquiring Stock pursuant to a Stock Option
to represent to and agree with the Corporation in writing that such person is
acquiring the shares without a view to distribution thereof.

         No shares of Stock shall be issued pursuant to a Stock Option until all
applicable securities law and other legal and stock exchange or similar
requirements have been satisfied. The Administrator may require the placing of
such stop-orders and restrictive legends on certificates for Stock and Stock
Options as it deems appropriate.

         (b) Delivery of Stock Certificates. Stock certificates to participants
under this Plan shall be deemed delivered for all purposes when the Corporation
or a stock transfer agent of the Corporation shall have mailed such certificates
in the United States mail, addressed to the participant, at the participant's
last known address on file with the Corporation.


                                       A-9
   37
         (c) Other Compensation Arrangements; No Employment Rights. Nothing
contained in this Plan shall prevent the Board from adopting other or additional
compensation arrangements, including trusts, and such arrangements may be either
generally applicable or applicable only in specific cases. The adoption of this
Plan and the grant of Stock Options do not confer upon any employee any right to
continued employment with the Corporation or any Subsidiary.

         (d) Trading Policy Restrictions. The Board of Directors or the
Administrator may establish insider-trading-policy-related restrictions, terms
and conditions, or other related policies, and may change these from time to
time, and all Stock Option shall be subject to these restrictions, terms,
conditions or other related policies.


SECTION 12.  EFFECTIVE DATE OF PLAN

         This Plan shall become effective upon approval by the holders of a
majority of the votes cast at a meeting of stockholders at which a quorum is
