     benefits:

               (i)  For a period of six months subsequent to the date of the
               Executive's death, the Employers shall continue to pay an amount
               equal to the Executive's salary to the Executive's beneficiary
               designated in writing to the Employers prior to his death (or to
               his estate, if he fails to make such designation) at the salary
               rate in effect on the date of his death (unless an increased rate
               shall previously have been authorized to take effect as of a
               later date, in which case such increased rate shall apply), said
               payments to be made on the same periodic dates as salary payments
               would have been made to the Executive had he not died.

               (ii) For a period of six months subsequent to the date of the
               Executive's death, the Executive's beneficiary designated in
               writing to the Employers prior to his death (or to his estate, if
               he fails to make such designation) shall continue to receive all
               benefits described in Section 4(b) above existing on the date of
               death (except for any cash bonus plans which shall be pro-rated
               through the date of death). For purposes of application of such
               benefits, the Executive shall be treated as if he had remained in
               the employ of the Employers, with an annual total salary at the
               rate in effect on the date of death (unless an increased rate
               shall previously have been authorized to take effect as of a
               later date, in which case such increased rate shall


<PAGE>   5


               apply), and service credits will continue to accrue during such
               period as if the Executive has remained in the employ of the
               Employers.
               (iii) If, in spite of the provisions of Section 7(a)(ii) above,
               benefits or service credits under any benefit plan shall not be
               payable or accrued under any such plan to the Executive, or to
               the Executive's beneficiary or estate, because the Executive is
               no longer deemed to be an employee of the employers, the
               Employers themselves shall pay or provide for payment of such
               benefits (calculated as if all such service credits had been
               accrued) to or for the benefit of the Executive, or to the
               Executive's beneficiary or estate.

          (b)  TERMINATION BY THE EMPLOYERS FOR CAUSE. The Executive's
     employment hereunder may be terminated without further liability on the
     part of the Employers effective immediately by a resolution of the Board of
     Directors of the Company or the Bank, as the case may be, for cause by
     written notice to the Executive setting forth in reasonable detail the
     nature of such cause. Only the following shall constitute "cause" for such
     termination:

               (i)  Deliberate dishonesty of the Executive with respect to the
               Employers or any subsidiary or affiliate thereof.

               (ii) Conviction of the Executive of a crime involving moral
               turpitude.

Gross and willful failure to perform a substantial portion of his duties and
responsibilities hereunder.

          (a)  TERMINATION BY THE EXECUTIVE. The Executive's employment
     hereunder may be terminated effective immediately by the Executive by
     written notice to the Board immediately by the Executive by written notice
     to the Board of Directors of the Company or the Bank, as the case may be,
     in the event of material breach by either of the Employers of this
     Agreement. From and after the effective date of any termination by the
     Executive of his employment hereunder, in the absence of such a breach by
     the Company or the Bank, as the case may be, the Employers will have no
     further liability to the Executive for salary or other compensation or
     benefits, except as provided pursuant to compensation or benefits, except
     as provided pursuant to any other agreement to which the Executive and the
     Employers are parties or any compensation or benefit plan of the Employers
     in which the Executive is a participant.

          (b)  TERMINATION BY THE EMPLOYERS WITHOUT CAUSE. The Executive's
     employment with the Company or the Bank, as the case may be, may be
     terminated without cause by a resolution of the


<PAGE>   6


     Board of Directors of the Company or the Bank, respectively, on written
     notice to the Executive.

          (c)  CERTAIN TERMINATION BENEFITS. In the event of termination
     pursuant to the first sentence of Section 7(c) or pursuant to Section 7(d),
     the Executive shall be entitled to the following benefits:

               (i)  For the period subsequent to the date of termination until
               the Expiration Date, the Employers shall continue to pay the
               Executive a total salary at the rate in effect on the date of
               termination (unless an increased rate shall previously have been
               authorized to take effect as of a later date, in which case such
               increased rate shall apply).
               (ii) For the period subsequent to the date of termination until
               the Expiration Date, the Executive shall continue to receive all
               benefits described in Section 4(b) above existing on the date of
               termination (except for any cash bonus plans, which shall be
               pro-rated through the date of termination). For purposes of
               application of such benefits, the Executive shall be treated as
               if he had remained in the employ of the employers, with an annual
               total salary at the rate in effect on the date of termination
               (unless an increased rate shall previously have been authorized
               to take effect as of a later date, in which case such increased
               rate shall apply) and service credits will continue to accrue
               during such period as if the Executive had remained in the employ
               of the Employers.
               (iii) If, in spite of the provisions of Section 7(e)(ii) above,
               benefits or service credits under any benefit plan shall not be
               payable or accrued under any such plan to the Executive, or to
               the Executive's dependents, beneficiaries or estate, because the
               Executive is no longer deemed to be an employee of the Employers,
               the Employers themselves shall pay or provide for payment of such
               benefits (calculated as if all such service credits had been
               accrued) to or for the benefit of the Executive or the
               Executive's dependents, beneficiaries or estate.

               (a)  SET-OFF. The Employers shall be entitled to set off against
          any cash compensation to be provided to the Executive under Section
          7(e)(i) above, one-half of the amount of any cash compensation
          received by the Executive from other employment during the period in
          which the Executive receives cash compensation under Section 7(e)(i).
          The Executive shall inform the Employers of any such amounts of cash
          compensation and shall refund to the Employers any amounts which the
          Employers have paid which exceed the amounts due from the employers
          after application of the set-off provided for in this paragraph.
          Notwithstanding the foregoing and any other provision of this
          Agreement, the Executive shall be under no obligation to seek or
          accept any employment after termination of employment with the
          Employers for any reason.

     8.   DISABILITY. If, due to physical or mental illness, the Executive shall
be disabled so as to be unable to perform substantially all of his duties and
responsibilities hereunder, the Board of Directors of the Company or the Bank,
as the case may be, may designate another executive to act in his place during
the period of such disability. Notwithstanding any such designation, the
Executive shall continue to receive his full salary and benefits under Section 4
of this Agreement until he becomes eligible for disability income under the
employers' disability income plan. While receiving disability income payments
under such plan, the Executive shall not receive any salary under Section 4(a),
but shall continue to participate in the Employers' benefit plans and to receive
other benefits as specified in Section 4 until the Expiration Date. In the
absence of a disability income plan at the time of such disability, the
Employers shall pay the Executive benefits equal to those the Executive would
have received if the Employers' current disability income plan were in effect at
such time. If any question shall arise as to whether during any period the
Executive was disabled so as to be unable to perform substantially all of his
duties and responsibilities and at the request of the Employers will, submit to
the Employers a certification in reasonable detail by a physician selected by
the Executive or his guardian to whom the employers have no reasonable objection
as to whether the Executive was so disabled and such certification shall for the
purposes of this Agreement be conclusive of the issue. If such question shall
arise and the Executive shall fail to submit such certification, the Employer's
determination of such issue shall be binding on the Executive.

     9.   NONCOMPETITION AND CONFIDENTIAL INFORMATION.

          (a)  NONCOMPETITION. During the term of the Executive's employment
     hereunder, and either (i) a period of one year following the date of
     termination of the Executive's employment with either the Company or the
     Bank by the Executive or by either of the Employers for cause pursuant to
     Section 7(b) hereof, or (ii) the period during which the Employers continue
     to provide benefits to the Executive pursuant to Sections 7(e)(i) - (iii)
     hereof in the event of termination pursuant to the first sentence of
     Section 7(c) or pursuant to Section 7(d), the Executive shall not directly
     or indirectly, whether as owner, partner, shareholder (other than as the
     owner of less than 2% of the outstanding capital stock of a publicly-traded
     corporation), consultant, agent, employee, co-venturer or otherwise, of or
     through any Person (as defined in Section 11) having its main office in the
     Employers' market area (defined as the Massachusetts municipalities of
     Andover, North Andover, Lawrence, Methuen and Tewksbury) compete in said
     market area with the banking or any other business conducted by either of
     the Employers during the period of his employment hereunder, nor will he
     attempt to hire any employee of either of the Employers, assist in such
     hiring by any other Person, encourage any such


<PAGE>   8


     employee to terminate his or her relationship with either of the Employers,
     or solicit or encourage any customer of either of the Employers to
     terminate its relationship with such Employer or to conduct with any other
     Person any business or activity which such customer conducts or could
     conduct with such Employer.

          (b)  CONFIDENTIAL INFORMATION. The Executive will not disclose to any
     other Person (except as required by applicable law or in connection with
     the performance of his duties and responsibilities hereunder), or use for
     his own benefit or gain, any confidential information of either of the
     Employers obtained by him incident to his employment with the Employers.
     The term "confidential information" includes, without limitation, financial
     information, business plans, prospects and opportunities (such as lending
     relationships, financial product developments, or facilities) which have
     been discussed or considered by the management of the Employers but does
     not include any information which has become part of the public domain by
     means other than the Executive's non-observance of his obligations
     hereunder. Notwithstanding anything to the contrary herein, this provision
     shall survive any termination of this Agreement.

          (c)  RELIEF; INTERPRETATION. The Executive agrees that the Employers
     shall be entitled to injunctive relief for any breach by him of the
     covenants contained in Sections 9(a) or 9(b). In the event that any
     provision of this Section 9 shall be determined by any court of competent
     jurisdiction to be unenforceable by reason of its being extended over too
     great a period of time, too large a geographic area, or too great a range
     of activities, it shall be interpreted to extend only over the maximum
     period of time, geographic area, or range of activities as to which it may
     be enforceable. For purposes of this Section 9, the term "Employers" shall
     mean the Company, the Bank and any of their respective subsidiaries or
     affiliates.

     10.  CONFLICTING AGREEMENTS. The Executive hereby represents and warrants
that the execution of this Agreement and the performance of hi obligations
hereunder will not breach or be in conflict with any other agreement to which he
is a party or is bound, and that he is not now subject to any covenants against
competition or similar convenants which would affect the performance of his
obligations hereunder.

     11.  DEFINITION OF "PERSON". For purposes of this Agreement, the term
"Person" shall mean an individual, a corporation, an association, a partnership,
an estate, a trust and any other entity or organization.

     12.  WITHHOLDING. All payments made by the Employers under this Agreement
shall be net of any tax or other amounts required to be withheld by the
Employers under applicable law.


<PAGE>   9


     13.  Arbitration of Disputes. Any controversy or claim arising out of or
relating to this Agreement or the breach thereof shall be settled by arbitration
in accordance with the laws of the Commonwealth of Massachusetts by three
arbitrators, one of whom shall be appointed by the Employers, one by the
Executive and the third by the first two arbitrators. If the first two
arbitrators cannot agree on the appointment of a third arbitrator, then the
third arbitrator shall be appointed by the American Arbitration Association in
the City of Boston. Such arbitration shall be conducted in the City of Boston in
accordance with the rules of the American Arbitration Association, except with
respect to the selection of arbitrators which shall be as provided in this
Section 13. Judgment upon the award rendered by the arbitrators may be entered
in any court having jurisdiction thereof. In the event that it shall be
necessary or desirable for the Executive to retain legal counsel and/or incur
other costs and expenses in connection with the enforcement of any or all of the
Executive's rights under this Agreement, the Employers shall pay (or the
Executive shall be entitled to recover from the Employers, as the case may be)
the Executive's reasonable attorneys' fees and other reasonable costa and
expenses in connection the enforcement of said rights (including the enforcement
of any arbitration award in court) regardless of the final outcome, unless and
to the extent the arbitrators shall determine that under the circumstances
recovery by the Executive of all or a part of any such fees and costs and
expenses would be unjust.

     14.  Assignment; Successors and Assigns, etc. Neither the Employers nor the
Executive may make any assignment of this Agreement or any interest herein, by
operation of law or otherwise, without the prior written consent of the other
party; provided, however, that the Employers may assign its rights under this
Agreement without the consent of the Executive in the event either of the
Employers shall hereafter effect a reorganization, consolidate with or merge
into any other Person, or transfer all or substantially all of its properties or
assets to any other Person. This Agreement shall inure to the benefit of and be
binding upon the Employers and the Executive, their respective successors,
executors, administrators, heirs and permitted assigns. In the event of the
Executive's death prior to the completion by the employers of all payments due
him under this Agreement, the Employers shall continue such payments to the
Executive's beneficiary designated in writing to the Employers prior to his
death (or to his estate, if he fails to make such designation).

     15.  Enforceability. If any portion or provision of this Agreement shall to
any extent be declared illegal or unenforceable by a court of competent
jurisdiction, then the remainder of this Agreement, or the application of such
portion or provision in circumstances other than those as to which it is so
declared illegal or unenforceable, shall not be affected thereby, and each
portion and provision of this Agreement shall be valid and enforceable to the
fullest extent permitted by law.

     16.  ALLOCATION OF OBLIGATIONS BETWEEN EMPLOYERS. The obligations of the
Employers under this Agreement are intended to be the joint and several
obligations of the Bank and the Company and the Employers shall, as between
themselves, allocate these obligations in a manner agreed upon by them.

     17.  WAIVER. No waiver of any provision hereof shall be effective unless
made in writing and signed by the waiving party. The failure of any party to
require the performance of any term or obligation of this Agreement, or the
waiver by any party of any breach of this Agreement, shall not prevent any
subsequent enforcement of such term or obligation or be deemed a waiver of any
subsequent breach.

     18.  NOTICES. Any notices, requests, demands and other communications
provided for by this Agreement shall be sufficient if in writing and delivered
in person or sent by registered or certified mail, postage prepaid, to the
Executive at the last address the Executive has filed in writing with the
Employers or, in the case of the Bank, at its main offices, attention of the
Clerk or, in the case of the Company, at its main office, attention of the
Secretary.

     19.  AMENDMENT. This Agreement may be amended or modified only be a written
instrument signed by the Executive and by a duly authorized representative of
each of the Employers.

     20.  GOVERNING LAW. This is a Massachusetts contract and shall be construed
under and be governed in all respects by the laws of the Commonwealth of
Massachusetts.

     IN WITNESS WHEREOF, this Agreement has been executed as a sealed instrument
by the Executive and by the Employers, by its duly authorized officer, as of the
date first above written.

                     ANDOVER BANCORP, INC. STOCK OPTION PLAN

                                                        May 8, 1986
                                                        as amended May 22, 1986,
                                                        January 29, 1987 and
                                                        November 2, 1987

1.   PURPOSE

     This Stock Option Plan (the "Plan") is intended as a performance incentive
for officers and full-time employees of Andover Bancorp, Inc. (the
"Corporation") or its Subsidiaries (as hereinafter defined) to enable the
persons to whom options are granted (the "Optionees") to acquire or increase a
proprietary interest in the success of the Corporation. The Corporation intends
that this purpose will be effected by the granting of "incentive stock options"
("Incentive Options") as defined in Section 422A(b) of the Internal Revenue Code
of 1986, as amended (the "Code"), nonqualified stock options ("Nonqualified
Options") and stock appreciation rights under the Plan. The terms "Subsidiaries"
includes any corporations in which stock possessing fifty percent (50%) or more
of the total combined voting power of all classes of stock is owned directly or
indirectly by the Corporation.

2.   OPTIONS TO BE GRANTED AND ADMINISTRATION

     (a)  Options granted under the Plan may be either Incentive Options or
Nonqualified Options.

     (b)  The Plan shall be administered by a committee (the "Option Committee")
of not less than three directors appointed by the Board of Directors of the
Corporation. None of the members of the Option Committee shall be an officer or
other full-time employee of the Corporation. No person shall serve as a member
of the Option Committee if such person is then eligible, or has been eligible at
any time during the prior twelve months, to receive stock options, or stock
appreciation rights under the Plan or any other option, stock purchase or
similar plan of the Corporation or its Subsidiaries. It is the intention of the
Corporation that the Plan shall be administered, in accordance with the
provisions of Section 4 hereof, in a manner consistent with the provisions of
Rule 16b-3(b) (entitled "Disinterested Administrators") as promulgated by the
Securities and Exchange Commission under the Securities Exchange Act of 1934, as
amended (the "1934 Act"). Action by the Option Committee shall require the
affirmative vote of a majority of all its members.

     (c)  Subject to the terms and conditions of the Plan, the Option Committee
shall have the power:


<PAGE>   2


          (i)  To determine from time to time the options to be granted to
          eligible persons under the Plan and to prescribe the terms and
          provisions (which need not be identical) of each option granted under
          the Plan to such persons;
          (ii) To construe and interpret the Plan and options granted thereunder
          and to establish, amend, and revoke rules and regulations for
          administration of the Plan. In this connection, the Option Committee
          may correct any defect or supply any omission, or reconcile any
          inconsistency in the Plan, or in any option agreement, in the manner
          and to the extent it shall deem necessary or expedient to make the
          Plan fully effective. All decisions and determinations by the Option
          Committee in the exercise of this power shall be final and binding
          upon the Corporation and Optionees; and
          (iii) Generally, to exercise such powers and to perform such acts as
          are deemed necessary or expedient to promote the best interests of the
          Corporation with respect to the Plan.

3.   STOCK

     (a)  The stock subject to the options granted under the Plan shall be
shares of the Corporation's authorized but unissued common stock, par value $.10
per share (the "Common Stock"). The total number of shares that may be issued
pursuant to options or stock appreciation rights granted under the Plan shall
not exceed an aggregate of 500,000 shares of Common Stock. Such number shall be
subject to adjustment as provided in Section 8 hereof.

     (b)  Whenever any outstanding option under the Plan expires, is cancelled
or is otherwise terminated (other than by exercise), the shares of Common Stock
allocable to the unexercised portion of such option may again be the subject of
options under the Plan, except for options surrendered as provided in Section 7
hereof.

4.   ELIGIBILITY

     (a)  Incentive Options and/or Nonqualified Options may be granted only to
officers and other full-time employees of the Corporation or its Subsidiaries,
including members of the Board of Directors who are also officers or other
full-time employees of the Corporation or its Subsidiaries.

     (b)  No person shall be eligible to receive any option under the Plan, if
at the date of grant such person beneficially owns in excess of ten percent
(10%) of the outstanding Common Stock of the Corporation.


<PAGE>   3


     (c)  With respect to Incentive Options granted after December 31, 1986, the
aggregate fair market value (determined at the time each respective option is
granted) of the stock with respect to which Incentive Options are exercisable
for the first time by any individual during any calendar year (under all plans
of the Corporation and its parent and subsidiary corporations as defined in
Section 425 of the Code) shall not exceed $100,000. Any option granted in excess
of the foregoing limitation shall be clearly and specifically designated as not
being an Incentive Option.

5.   TERMS OF THE OPTION AGREEMENTS

     Each option agreement shall contain such provisions as the Option Committee
shall from time to time deem appropriate. Option agreements need not be
identical, but each option agreement by appropriate language shall include the
substance of all of the following provisions:

     (a)  EXPIRATION. Notwithstanding any other provision of the Plan or of any
option agreement, each option shall expire on the date specified in the option
agreement, which date shall not be later than the tenth anniversary of the date
on which the option was granted.

     (b)  MINIMUM SHARES EXERCISABLE. The minimum number of shares with respect
to which an option may be exercised at any one time shall be 100 shares, or such
lesser number as is subject to exercise under the option at the time.

     (c)  EXERCISE.

          (i)  Each option shall be exercisable in such installments (which need
     not be equal) and at such times as designated by the Option Committee. To
     the extent not exercised, installments shall accumulate and be exercisable,
     in whole or in part, at any time after becoming exercisable, but not later
     than the date the option expires.

          (ii) In the event of a Change in Control of the Corporation (as
     defined in (f) below), all options outstanding as of the date of such
     Change in Control shall become vested and immediately exercisable.

          (iii) The exercise of options granted hereunder shall be subject to
     the receipt of any prior regulatory approvals that may be required.

     (d)  PURCHASE PRICE. The purchase price per share of Common Stock under
each option shall be not less than the fair market value of the Common Stock on
the date the option is granted. For the purposes of the Plan, the fair market
value of the Common Stock shall be determined in good faith by the Option
Committee.

     (e)  RIGHTS OF OPTIONEES. No Optionee shall be deemed for any purpose to be
the owner of any shares of Common Stock subject to any option unless and until
(i) the option shall have been exercised pursuant to the terms thereof, (ii) the
Corporation shall have issued and delivered the Shares to the Optionee, and
(iii) the Optionee's name shall have been entered as a stockholder of record on
the books of the Corporation. Thereupon, the Optionee shall have full voting,
dividend and other ownership rights with respect to such shares of Common Stock.

     (f)  CHANGE IN CONTROL. For purposes of the Plan, a "Change in Control"
shall be deemed to have occurred in either of the following events: (i) if there
has occurred a change in control which the Corporation would be required to
report in response to Item 1 of Form 8-K promulgated under the 1934 Act, or, if
such regulation is no longer in effect, any regulations promulgated by the
Securities and Exchange Commission pursuant to the 1934 Act which are intended
to serve similar purposes or (ii) when any "person" (as such term is used in
Section 13(d) and 14(d)(2) of the 1934 Act) becomes a "beneficial owner" (as
such term is defined in Rule 13d-3 promulgated under the 1934 Act), directly or
indirectly, of securities of the Corporation representing twenty-five percent
(25%) or more of the total number of votes that may be generally cast for the
election of directors of the Corporation, and in the case of either (i) or (ii)
above, the Corporation's Board of Directors has not consented to such event by a
two-thirds vote of all of the members of the Board of Directors then in office
adopted prior to such event. In addition, a Change in Control shall be deemed to
have occurred if, as the result of, or in connection with, any tender or
exchange offer, merger or other business combination, sale of assets or
contested election, or any combination of the foregoing transactions, persons
who were directors of the Corporation before such transaction shall cease to
constitute a majority of the Board of Directors of the Corporation or of any
successor institution.

     (g)  TRANSFER. No options or stock appreciation rights shall be
transferable by the Optionee other than by will or the laws of descent and
distribution, and options or stock appreciation rights may be exercised during
the Optionee's lifetime only by the Optionee, or his or her guardian or legal
representative.

6.   METHOD OF EXERCISE; PAYMENT OF PURCHASE PRICE

     (a)  Any option granted under the Plan may be exercised by the Optionee by
delivering to the Option Committee on any business day a written notice
specifying the number of shares of Common Stock the Optionee then desires to
purchase (the "Notice").


<PAGE>   5


     (b)  Payment for the shares of Common Stock purchased pursuant to the
exercise of an option shall be made either in (i) cash equal to the option price
for the number of shares specified in the Notice (the "Total Option Price"), or
(ii) if authorized by the applicable option agreement, shares of Common Stock of
the Corporation having a fair market value, as determined in good faith by the
Option Committee, equal to or less than the Total Option Price, plus cash in an
amount equal to the excess, if any of the Total Option Price over the fair
market value of such shares of Common Stock.

7.   STOCK APPRECIATION RIGHTS

     (a)  The Option Committee may, but shall not be obligated to, include stock
appreciation rights in any option agreement, on such terms and conditions as it
deems appropriate in each case. Such stock appreciation rights shall permit the
Optionee, at his or her election, to surrender to the Corporation the right to
exercise such option (or portion thereof) in consideration for the payment by
the Corporation of any amount equal to the excess of the fair market value on
the date of such surrender of the shares of Common Stock subject to such option
(or portion thereof) surrendered over the exercise price of such shares. Such
payment may be made, at the discretion of the Option Committee upon the request
of the Optionee, in shares of Common Stock valued at the fair market value
thereof on the date of such surrender or in cash, or any combination thereof.

     (b)  Any election by an Optionee to exercise stock appreciation rights
included in any option agreement by settlement in cash shall be made only during
the period beginning on the third business day following the date of the release
for publication of quarterly or annual financial information and ending on the
twelfth business day following such date. This condition shall be deemed to be
satisfied when the specified financial data appears on or in a wire service,
financial news service or newspaper of general circulation or is otherwise first
made publicly available. No stock appreciation right may be exercised within six
months from the date of grant thereof, except that this limitation shall not
apply in the event that death or disability of the Optionee occurs prior to the
expiration of such six-month period.

     (c)  Any option surrendered as provided in this Section 7 shall be
cancelled by the Corporation and shall not be subject to further grant.

     (d)  The Option Committee shall be authorized hereunder to make payment to
the Optionee in shares of Common Stock only if Section 61 and 83 of the Code
apply to the Common Stock transferred to the Optionee.


<PAGE>   6


     (e)  Notwithstanding the foregoing, a stock appreciation right may not be
settled in either cash or shares of the Corporation's Common Stock, if such
settlement would result in the settlement of the stock appreciation right not
complying with Rule 16b-3(e) under the Exchange Act or any successor provision
thereto.

8.   ADJUSTMENT UPON CHANGES IN CAPITALIZATION

     (a)  If the shares of the Corporation's Common Stock as a whole are
increased, decreased, changed into or exchanged for, a different number or kind
of shares or securities of the Corporation, whether through merger,
consolidation, reorganization, recapitalization, reclassification, stock
dividend, stock split, combination of shares, exchange of shares, change in
corporate structure or the like, an appropriate and proportionate adjustment
shall be made in the number and kind of shares subject to the Plan and in the
number, kind, and per share exercise price of shares or other securities subject
to unexercised options or portions thereof granted prior to any such change. In
the event of any such adjustment in an outstanding option, the Optionee
thereafter shall have the right to purchase the number of shares or securities
under such option at the per share price or per unit price, as so adjusted,
which the Optionee could purchase for the total purchase price applicable to the
option immediately prior to such adjustment.

     (b)  Adjustments under this Section 8 shall be determined by the Option
Committee and such determinations shall be conclusive. The Option Committee
shall have the discretion and power in any such event to determine and to make
effective provision for acceleration of the time or times at which any option or
portion thereof shall become exercisable. No fractional shares of Common Stock
shall be issued under the plan on account of any adjustment specified above.

9.   EFFECT OF CERTAIN TRANSACTIONS

     In the case of (i) the dissolution or liquidation of the Corporation, (ii)
a reorganization, merger or consolidation in which the Corporation is acquired
by another entity or in which the Corporation is not the surviving corporation,
or (iii) the sale of all or substantially all of the property of the Corporation
to another corporation, the Plan and the options issued hereunder shall
terminate on the effective date of such transaction, unless provision is made in
connection with such transaction for the assumption of options theretofore
granted under the Plan, or the substitution for such options of new options of
the successor corporation or parent thereof, with appropriate adjustment as to
the number and kind of shares and the per share exercise prices, as provided in
Section 8. In the event of such termination, all outstanding options shall be
exercisable in full for at least 15 days prior to the date of such termination
whether or not otherwise exercisable during such period.


<PAGE>   7


10.  RELEASE OF FINANCIAL INFORMATION

     A copy of the Corporation's annual report to stockholders shall be
delivered to each Optionee at the time such report is distributed to the
Corporation's stockholders. Upon request, the Corporation shall furnish to each
Optionee a copy of its most recent annual report and each quarterly report and
current report filed under the 1934 Act since the end of the Corporation's prior
fiscal year.

11.  AMENDMENT OF THE PLAN

     The Board of Directors may amend the Plan at any time, and from time to
time, subject to any required regulatory approval and to the limitation that,
except as provided in Sections 8 and 9 hereof, no amendment shall be effective
unless approved by the stockholders of the Corporation in accordance with
applicable law and regulations at an annual or special meeting held within
twelve months before or after the date of adoption of such amendment, where such
amendment will:

     (a)  increase the number of shares of Common Stock as to which options may
be granted under the Plan;

     (b)  change in substance Section 4 hereof relating to eligibility to
participate in the Plan;

     (c)  change the minimum option price;

     (d)  increase the maximum term of options provided herein; or

     (e)  otherwise materially increase the benefits accruing to participants
under the Plan.

     Except as provided in Sections 8 and 9 hereof, rights and obligations under
any option granted before any amendment of the Plan shall not be altered or
impaired by such amendment, except with the consent of the Optionee.

12.  NONEXCLUSIVITY OF THE PLAN

     Neither the adoption of the Plan by the Board of Directors nor the
submission of the Plan to stockholders for approval shall be construed as having
created any limitations on the power of the Board of Directors to adopt such
other incentive arrangements as it may deem desirable, including, without
limitation, the granting of stock options otherwise than under the Plan, and
such arrangements may be either applicable generally or only in specific cases.


<PAGE>   8


13.  GOVERNMENT AND OTHER REGULATIONS; GOVERNING LAW

     (a)  The obligation of the Corporation to sell and deliver shares of Common
Stock with respect to options granted under the Plan shall be subject to all
applicable laws, rules and regulations, including all applicable federal and
state securities laws, and the obtaining of all such approvals by governmental
agencies as may be deemed necessary or appropriate by the Option Committee.

     (b)  The Plan shall be governed by Massachusetts law, except to the extent
that such law is preempted by federal law.

     (c)  The Plan is intended to comply with the provisions of Rule 16b-3
promulgated under the 1934 Act. Any provision inconsistent with such Rule shall
be inoperative and shall not affect the validity of the Plan.

14.  TERMINATION OF GRANTING OF OPTIONS UNDER PLAN

     No option may be granted under the Plan after May 8, 1996, which is the
tenth anniversary of the date the Plan became effective as the Andover Savings
Bank 1986 Stock Option Plan.

      1999          LETTER
                   -------------------------------------------------------------
                       TO SHAREHOLDERS


Dear Shareholders,

As I prepare to write this letter every year, I gather material that I have set
aside during the year as reminders of events and accomplishments, which should
be reported to you. Just before writing, I go back and reread last year's
letter. I was struck by how similar, only even better, this year's report to you
would be.

Last year I reported the fifth consecutive year of record earnings. This year, I
am pleased to report a sixth consecutive year of record earnings. The extent of
our success this year is reflected in the following financial highlights for
1999:

     -    Record earnings of $18.9 million, an increase of 9%
     -    Return on average assets increased to 1.31%
     -    Return on average equity of 15.05%
     -    Dividends of $0.87 per share, a 26% increase

In 1999, loan growth was coupled with a 6% increase in net interest margin,
while the earning increase in 1998 was primarily the result of loan growth,
which offset a decline in net interest margin. As in 1998, almost every loan
category witnessed growth in 1999, with special success in the following
categories:

     -    Commercial real estate loans increased by 26%
     -    Commercial and industrial loans increased by 49%
     -    Construction loans increased by 13%
     -    Equipment leases increased by 192%

I cannot conclude any discussion of loan growth without referring to credit
quality. This year's level of problem and delinquent loans is even below last
year's minimal level.

The excellent results and similarities in both the amount and sources of growth
from year to year indicate the fundamental strength of the Bank's core
businesses. The excellent returns on assets and equity validate both the Bank's
strategies and their execution. They further indicate the Bank's ability to meet
profitably the financial needs of its customers and marketplace.

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


For the year ahead, we look to augment those fundamentally strong operating
principles with expanded geography and new non-traditional products.

One of our most exciting expansion developments is our pending acquisition of
Gloucester Bank and Trust ("Gloucester Bank"). Gloucester Bank offers both
geographic and product expansion opportunities. As a commercial bank, it will
strengthen our commercial lending capabilities. Additionally, Gloucester Bank
offers us a new market to offer our broader, more competitively priced
residential mortgage and consumer loan products.

As I have reported to you before, Andover Bank's expansion into southern New
Hampshire has been extraordinarily well received. Our deposit and loan growth
and our gain in market share have greatly exceeded our expectations. Seeking to
capitalize and expand on that success, we have begun construction on a new
banking office in Derry. Based on marketing data and our positive reception in
neighboring Londonderry, we are excited about the prospects for this new office.
In addition, other expansion efforts occurred in Tewksbury, where Andover Bank
already enjoys the largest market share. Our new Tewksbury office is a larger
facility that offers greater customer convenience and access.

With regard to new products, we are excited about the banks recently initiated
insurance program. We are now offering a complete line of consumer and
commercial insurance products through our newly formed subsidiary, AB Insurance
Services. We look to offer our insurance products with very attractive,
competitive rates and the superior service our customers have come to expect.
Insurance represents only our most recent new product offering. It is our goal
to continue to broaden our array of products and services to meet all the
financial needs of our customers.

In addition to the challenge of increasing the services we provide, we must
continually strive to improve both the quality and convenience of our delivery
of those products. In this "electronic age," the delivery convenience of more
banking office locations must be matched with improvements in electronic and
remote product and service delivery.

                    Letter to Shareholders (continued)
                 ---------------------------------------------------------------


Once it might have seemed a leap to go from discussing on-line banking to
reporting on our record of community lending and service. In a world of
e-tailers and e-mailers, both traditional and electronic banking are running
together. Last year, I was proud to report that the Commonwealth of
Massachusetts awarded Andover Bank an "Outstanding" rating for its performance
under the Community Reinvestment Act. As a state chartered, federally insured
bank, Andover Bank is examined annually by either the Commonwealth or the FDIC
on alternating years. I am pleased to report that the FDIC also awarded Andover
Bank with an "Outstanding" rating this year. This recognition, by both our
state and federal regulators, validates our strong commitment, throughout the
Bank, to serve, equitable and well, our entire community.

After reporting all the positive news of 1999, I know that shareholders, like
all of us at the Bank, are disappointed by the stock's price performance. One
would hope and expect that financial markets would recognize and reward our
superior results. There has been a divergence between the valuation of
traditional companies and the new high-tech companies. Investors are enamored by
the stratospheric returns presently enjoyed by technology stocks. Our stock
price shares its lagging performance with many traditional industries, including
the entire financial services industry. All we can do is to continue to operate
as successfully as possible, to record superior results and to trust that the
investment community will again appreciate the value of reliable earnings
growth.

On behalf of the Board of Directors, I wish to thank our Shareholders for their
continued support and the Employees for their commitment in achieving the
excellent results recorded over the past year.

performance or achievements including, without limitation, the Bank's (as
defined below) continued ability to originate quality loans, fluctuation of
interest rates, real estate market conditions in the Bank's lending area,
general and local economic conditions, the Bank's continued ability to attract
and retain deposits, the Company's (as defined below) ability to control costs,

                                     PART I

ITEM 1.  BUSINESS

GENERAL

     Andover Bancorp, Inc. ("Andover" or the "Company") is a Delaware
corporation that was organized in 1987. Although Andover has corporate authority
to engage in any activity permitted by the Delaware General Corporation Law,
Andover's primary activity is to act as the holding company for Andover Bank
(the "Bank").

     The Bank is a Massachusetts-chartered savings bank which was incorporated
in 1834 and is headquartered in Andover, Massachusetts. On May 8, 1986, Andover
Bank converted from mutual to stock form. Deposits at the Bank are insured by
the Federal Deposit Insurance Corporation ("FDIC") up to $100,000 per separately
insured account and by the Depositors Insurance Fund, Inc. ("DIF") for that
portion of deposits in excess of $100,000.

     On June 30, 1999, Andover Bank NH, a wholly-owned subsidiary of Andover,
was merged with and into Andover Bank. As a result, the two banking offices of
Andover Bank NH are currently operating as branches of Andover Bank.

     The Bank is engaged principally in the business of attracting deposits from
the general public and investing in residential and commercial real estate
loans, in construction, consumer, commercial loans and lease financing, and in
various securities. Emphasis is placed on both retail and corporate banking.
Retail activities, an important source of franchise value to the Bank, consist
of branch operations, home mortgage and consumer lending, and mortgage banking.
The Bank offers a variety of retail products through branch offices, automated
teller machines ("ATMs"), its telephone call center with its expanded hours,
online banking and product specialists. Other non-banking services available to
its customers include the recently initiated insurance program in addition to
the investment services provided by a third party. Corporate banking activities
consist primarily of commercial real estate, construction, land and commercial
lending and lease financing. These activities are conducted primarily by
experienced loan officers and business development specialists.


                                       3
<PAGE>   10


     The Company's strong financial performance in 1999 includes pre-tax gains
of $1.6 million from the termination of the Company's defined benefit pension
plan as well as an increase in the net interest margin while the Company's
financial performance in 1998 was positively impacted by a credit for loan
losses of $1.7 million and a tax benefit of $1.1 million.

     On January 26, 2000, the Company entered into a definitive agreement to
acquire GBT Bancorp ("GBT") and its wholly-owned subsidiary, Gloucester Bank and
Trust Company. This agreement is subject to customary closing conditions and a
number of approvals from various regulatory agencies. At December 31, 1999, GBT
had $130.9 in assets, primarily commercial real estate loans and investment
securities, and deposits of $103.5 million. The acquisition will be accounted
for as a purchase and had a total value on the date of announcement of
approximately $16.2 million and estimated goodwill of approximately $9.2
million.

MARKET AREA

     The Bank's market area is centered in Andover, Massachusetts, approximately
25 miles north of downtown Boston. The Bank operates banking offices in the
towns of Andover, Lawrence, Methuen, North Andover and Tewksbury, Massachusetts
and Salem and Londonderry, New Hampshire, which serve those towns as well as
surrounding communities in northeastern Massachusetts and in southern New
Hampshire. Andover Capital Group, Inc., a subsidiary of Andover Bank, offering
commercial equipment loans and lease financing, is located in Westford with the
entire Northeast as its primary market area.

LENDING ACTIVITIES

     General. Lending is the principal business of the Bank and loans represent
the largest portion of the Bank's assets. At December 31, 1999, the Bank's loan
portfolio, prior to the allowance for loan losses, amounted to $1.1 billion or
76.0% of total assets. The Bank's loan portfolio increased 7.8% during 1999
resulting primarily from higher corporate loan originations. For additional
information on the composition of the loan portfolio and loan originations, see
Note 4 to the "Consolidated Financial Statements" and Item F, "Management's
Discussion and Analysis -- Results of Operations -- Financial Condition --
Loans".

     The primary lending activity has been the origination of first mortgage
loans for the purchase or refinance of residential properties in Andover's
primary market area and adjacent communities. Such loans are generally viewed as
having less risk than other types of retail and non-retail loans and provide a
relatively stable source of interest income in the loan portfolio. They also
provide a significant source of fee income when they are sold in the secondary
mortgage market and serviced by the Bank. The Bank is an active servicer of
residential loans for investors in the secondary mortgage market.

     The Bank originates a variety of other loans for consumer purposes. These
include home equity, second mortgage, and personal loans, among others, and
constitute an additional source of interest income in the loan portfolio. The
consumer lending activities of the Bank complement its home mortgage activities
and position it as a full service retail lender. The retail lending activities
of the Bank complement the retail deposit gathering activities and strengthen
the overall retail franchise value. At December 31, 1999, retail loans totaled
$805.6 million or 71.1% of total loans.

     The Bank also originates non-retail or corporate loans, such as commercial
real estate, commercial, construction and land loans and lease financings.
Historically, these types of loans have generated higher yields and returns than
retail loans, but also involve additional risk. See "Risk Elements" below.
Corporate loans have also been viewed as a means of maintaining a diversified
loan and asset portfolio. At December 31, 1999, corporate loans amounted to
$327.5 million, or 28.9% of total loans.

     Residential Mortgage Loans. Residential mortgage loans totaling $743.7
million represented 65.6% of the total loan portfolio at December 31, 1999. An
additional $1.5 million in residential mortgage loans was held for sale at that
date. During 1999, the Bank purchased from other banks and correspondent
relationships $28.2 million of locally originated residential real estate whole
loans.


                                       4
<PAGE>   11


     Nearly all of the loans in the residential mortgage portfolio are secured
by homes located in Massachusetts or in southern New Hampshire. According to
internal policy, the majority of these loans are written to be eligible for sale
in the secondary mortgage market, primarily to the Federal Home Loan Mortgage
Corporation ("FHLMC") and the Federal National Mortgage Association ("FNMA").
Residential mortgage loans include both fixed and variable rate mortgages with
original terms of 5 to 30 years. The Bank remains an active seller of originated
home mortgages in the secondary market.

     Commercial Real Estate Loans. At December 31, 1999, commercial real estate
loans totaled $207.4 million, representing 18.3% of total loans. Approximately
$43.5 million, or 21.0% of these loans, are secured by apartment buildings and
multi-family residential properties. The balance of the commercial real estate
portfolio is secured by commercial facilities, including office, mixed use,
retail or light manufacturing properties, small shopping centers, and various
other types of commercial real estate. During 1999, the Bank purchased $10.1
million of commercial real estate first mortgages. Commercial real estate loans
generally amortize over a period of 15 to 25 years. Variable interest rates on
such loans are set at a margin above either the one-year Treasury index or the
prime rate as published in the Wall Street Journal and are subject to periodic
adjustment. Commercial real estate loans with fixed interest rates are generally
set at a margin above the equivalent Federal Home Loan Bank term advance rate.

     Construction and Land Loans. Construction and land loans totaled $63.7
million at December 31, 1999, representing 5.6% of total loans. At that date,
amounts committed but not yet advanced in connection with such loans totaled an
additional $26.5 million. At December 31, 1999, outstanding construction loans
totaled $34.5 million and outstanding land loans (including loans for unimproved
land and land development) totaled $29.2 million. The majority of the
construction loans are for residential development of single-family homes.
However, the Bank is increasingly undertaking commercial construction projects
at this time. Construction and land loans generally have a term of two years,
although the Bank typically is entitled to review and adjust the interest rate
at the end of the first year. The interest rate is set at a margin above the
prime rate as published in the Wall Street Journal.

     Consumer Loans. Consumer loans totaled $61.8 million at December 31, 1999,
representing 5.5% of total loans. Home equity lines constitute the greatest
portion of the Bank's consumer lending activity and totaled $41.7 million at
December 31, 1999. At that date, unadvanced amounts relating to home equity
lines totaled an additional $74.2 million. Home equity lines are offered both in
fixed rate and adjustable form with varying terms of three to ten years. The
adjustable rate loans are generally tied to the prime rate as published in the
Wall Street Journal. Home equity lines are subject to the same general
underwriting standards as residential first mortgage loans. Other consumer loans
are offered in fixed rate form with varying terms of three to eight years, while
second mortgages have terms of five to fifteen years.

     Commercial and Lease Loans. At December 31, 1999, commercial and lease
loans totaled $27.4 million, or approximately 2.4% of total loans. Secured
equipment loans included in the commercial and lease loan portfolio amounted to
$7.3 million and $4.9 million at December 31, 1999 and 1998, respectively. The
interest rate on commercial loans generally varies at a margin above the prime
rate as published in the Wall Street Journal. Commercial loans may be secured in
whole or in part by real estate unrelated to the principal purpose of the loan
or secured by inventories and receivables and are ordinarily guaranteed by the
principals of the borrower. Commercial loans with fixed interest rates are set
at a margin above the Federal Home Loan Bank advance rate.

     Lease Financing. Andover Capital Group, Inc. offers commercial equipment
loan and lease financing as an additional financing option for the Bank's
corporate customers. Total lease financing balances were $29.1 million and $10.0
million at December 31, 1999 and 1998, respectively.

     Loan Origination. Mortgage loans originate from a number of sources. These
include realtor, builder and customer referrals, direct advertising and
participation in home shows and other events. The Bank employs a number of
mortgage loan originators who maintain regular contact with real estate firms
and other sources of business and who respond to general mortgage inquiries.
These mortgage specialists are assigned specific territories and receive
commissions on closed mortgage loans. Total residential mortgages originated by
the Bank in 1999


                                       5
<PAGE>   12


amounted to $173.8 million. The decline in total residential originations from
1998 to 1999 was primarily due to lower mortgage refinancing activity
experienced throughout the year as a result of rising interest rates.

     Consumer loans are solicited by advertising and by direct mail targeted to
existing deposit and mortgage customers and, from time to time, selected market
area households which have no customer relationship with the Bank. The primary
origination activity in the consumer loan area relates to home equity lines of
credit and second mortgages, totaling $22.5 million in 1999, or nearly 82.2% of
the total consumer originations.

     Corporate originations, comprised of commercial real estate, commercial,
construction and land loans and lease financings, are originated from direct
solicitation of existing and prospective customers and from a variety of
referral sources. The Banks originated $174.3 million of these corporate loans
during 1999.

RISK ELEMENTS

     General. For further information concerning the composition of the loan
portfolio, nonaccrual loans, impaired loans and the allowance for loan losses,
see Note 4 to the "Consolidated Financial Statements" and Item 7, "Management's
Discussion and Analysis -- Results of Operations -- Financial Condition -- Risk
Elements.".

     Non-performing Assets. Non-performing assets consist of nonaccruing loans
and other real estate owned. During 1999, non-performing assets decreased 28.5%
or $995,000 from 1998 levels, to $2.5 million and amounted to 0.2% of total
assets at year-end. The Company places all loans, regardless of collateral
values, on nonaccrual status when principal or interest is past due 90 days or
more. Loans for which payments are less than 90 days past due are placed on
non-accrual status where there exists serious doubt as to collectibility. At
December 31, 1999, the Bank had $2.5 million in nonaccruing loans and $41,000 in
other real estate owned.

     Provision (Credit) for Loan Losses. The allowance for loan losses is
established through a provision for loan losses charged to the statement of
operations. The allowance is reduced by a credit for loan losses as well as loan
charge-offs. The Company recorded provisions for loan losses of $400,000 in 1999
as compared to a credit for loan losses of $1.7 million in 1998. Among the
factors used to determine that the provision for loan losses was appropriate
were the increase in corporate loan balances and the deterioration of two loans
on nonaccrual during the fourth quarter of 1999.

INVESTMENT ACTIVITIES

     The investment portfolio, an important component of Andover's asset
structure, is a source of earnings in the form of interest and dividends,
provides for diversification and is a source of liquidity. Overall, the
portfolio, comprised of mortgage-backed securities, corporate bonds, U.S.
Treasury and federal agency securities, short-term investments and equity
securities, represented 19.2% of total assets, or $286.7 million as of December
31, 1999.

     In 1999, the total investment portfolio produced interest and dividend
income of $19.8 million, or 19.8% of the total interest and dividend income
earned by the Company. The investment portfolio and the sale of loans generated
losses of $368,000 in 1999, as compared to gains of $670,000 in 1998 on sales,
redemptions and the marking of certain securities to market. For additional
information on investments, see Notes 1, 2 and 3 to the "Consolidated Financial
Statements" and Item 7, "Management's Discussion and Analysis -- Results of
Operations -- Financial Condition -- Investments".

DEPOSITS AND BORROWED FUNDS

     The Bank's major sources of funds are deposits, borrowings, principal
payments or payoffs on loans and mortgage-backed securities, and maturities of
investments. Borrowings are generally used to fund long-term assets and
short-term liquidity requirements or to manage interest rate risk. Total
deposits amounted to $968.5 million at December 31, 1999.


                                       6
<PAGE>   13


     The Bank is a member of the Federal Home Loan Bank of Boston ("FHLB") and
is authorized to borrow funds to meet withdrawals of savings deposits or to
expand the loan or investment portfolios. These borrowings are subject to
collateral requirements and borrowing limitations. The Bank also has available
various other sources of funds, including secured borrowings, federal funds
purchased or lines of credit from commercial banks and reverse repurchase
agreements from brokerage firms, FHLMC and FNMA. In addition, the Bank has
overnight repurchase agreements with various corporate customers. The Bank may
also obtain funds at the discount window of the Federal Reserve Bank of Boston.
At December 31, 1999, total borrowings outstanding from all of the Company's
various sources amounted to $379.4 million.

     For additional information concerning the composition and maturity of
deposits and borrowings, see Notes 8, 9 and 10 to the "Consolidated Financial
Statements" and Item 7, "Management's Discussion and Analysis -- Results of
Operations -- Financial Condition -- Deposits -- Borrowings -- Asset and
Liability Management and Market Risk -- Liquidity".

OTHER SERVICES

     Investment Services. The Bank makes investment and brokerage services
available to their customers through a contract with Liberty Securities
Corporation, an unaffiliated company. A fully licensed broker of Liberty
Securities located at the Bank's headquarters is available for consultation on
investment opportunities, including mutual funds, municipal bonds,
government-backed securities and annuities. The Bank received income of
approximately $68,000 from these services in 1999.

COMPETITION

     The Bank's lending and deposit-taking activities are concentrated in the
Merrimack Valley and the surrounding communities in northeastern Massachusetts
and southern New Hampshire. The Bank faces strong competition both in
originating loans and in attracting deposits. Competition in originating loans
in the Bank's expansive lending area comes primarily from thrift institutions,
commercial banks, mortgage companies, credit unions and consumer finance
companies. The Bank competes for loans principally on the basis of interest
rates and loan fees, the types of loans offered, and the quality of service and
convenience provided to borrowers.

     In attracting deposits, the Bank's primary competitors are thrift
institutions, commercial banks, credit unions and mutual funds. The attraction
and retention of deposits depends on the Bank's ability to provide investment
opportunities that satisfy the requirements of depositors with respect to the
rate of return, liquidity, risk, service and other factors. The Bank competes
for these deposits by offering competitive rates, convenient branch locations,
extended business hours, electronic delivery channels and automated teller
machines.

     On November 12, 1999, President Clinton signed into law the
Gramm-Leach-Bliley Act (the "Gramm-Leach-Bliley Act"). Under the
Gramm-Leach-Bliley Act, effective March 11, 2000, securities firms, insurance
companies and other financial services providers that elect to become financial
holding companies may acquire banks and other financial institutions. The
Gramm-Leach-Bliley Act may significantly change the competitive environment in
which the Company and its subsidiaries conduct business. See "Supervision and
Regulation -- Gramm-Leach-Bliley Act of 1999" below. The financial services
industry is also likely to become more competitive as further technological
advances enable more companies to provide financial services.

SUPERVISION AND REGULATION

     General. The Company and the Bank are heavily regulated. As a bank holding
company, Andover is supervised by the Board of Governors of the Federal Reserve
Board System ("the Federal Reserve Board") and it is also subject to the
jurisdiction of the Massachusetts Board of Bank Incorporation. The activities of
bank holding companies, such as Andover, that do not become financial holding
companies under the recently enacted Gramm-Leach-Bliley Act (as discussed below)
are limited to the business of banking and activities closely related or
incidental to banking. Provided that it does not become a financial holding
company, Andover may not directly or indirectly acquire the ownership or control
of more than 5 percent of any class of voting shares or substantially all of the


                                       7
<PAGE>   14


assets of any company that is not engaged in activities determined by the
Federal Reserve Board prior to November 12, 1999 by order or regulation to be
closely related to banking, and also generally must provide notice to or obtain
the approval of the Federal Reserve Board in connection with any such
acquisition. As a Massachusetts-chartered savings bank, the Bank is subject to
regulation, examination and supervision by the FDIC and the Massachusetts
Commissioner of Banks ("the Commissioner"). The Bank is also subject to certain
requirements established by the Federal Reserve Board.

     Federal Deposit Insurance Corporation. The FDIC insures the Bank's deposit
accounts up to the $100,000 maximum per separately insured account and is
subject to reporting requirements of the FDIC. The FDIC has adopted requirements
setting minimum standards for capital adequacy and imposing minimum leverage
capital ratios. The Bank exceeded all applicable requirements at December 31,
1999. Furthermore, under the capital standards established pursuant to the FDIC
Improvement Act of 1991, the Bank is currently well-capitalized. International
bank supervisory organizations, principally the Basel Committee on Banking
Supervision, currently are considering changes to the risk-based capital
adequacy framework, which ultimately could affect the FDIC's guidelines
regarding capital adequacy. For additional information on regulatory capital
ratios, see Note 12 to the "Consolidated Financial Statements" and Item 7,
"Management's Discussion and Analysis -- Financial Condition -- Capital

     Massachusetts Commissioner of Banks and Board of Bank Incorporation.
Massachusetts statutes and regulations govern, among other things, investment
powers, lending powers, deposit activities, maintenance of surplus and reserve
accounts, the distribution of earnings, the payment of dividends, issuance of
capital stock, branching, acquisitions and mergers and consolidations. Any
Massachusetts bank that does not operate in accordance with the regulations,
policies and directives of the Commissioner may be subject to sanctions for
noncompliance. The Commissioner may, under certain circumstances, suspend or
remove officers or directors who have violated the law, conducted the Bank's
business in a manner which is unsafe, unsound or contrary to the depositors'
interest, or been negligent in the performance of their duties. In response to a
Massachusetts law enacted in 1996, in 1997 and 2000, the Commissioner finalized
rules that generally give Massachusetts banks, and their subsidiaries, many
powers equivalent to those of national banks. The Commissioner also has adopted
regulations and procedures expediting the approval process for well-capitalized
banks to establish branches or to engage in certain activities.

     Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994. Under
the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (the
"Riegle-Neal"), certain interstate transactions and activities are permitted.
Interstate transactions and activities permitted for under the law include: (i)
bank holding company acquisitions of separately held banks in a state other than
a bank holding company's home state; (ii) mergers between banks with different
home states, including consolidations of affiliated banks; (iii) establishment
of interstate branches either de novo or by branch acquisition; and (iv)
affiliate banks acting as agents for one another for certain banking functions
without being considered a "branch". In general, subject to limitations,
nationwide interstate acquisitions are now permissible, irrespective of state
law limitations other than limitations related to deposit concentrations and
bank age requirements. Interstate mergers generally also are permissible, and
affiliated banks may act as agents for one another. Each of the transactions and
activities must be approved by the appropriate federal bank regulator, with
separate and specific criteria established for each category.

     In 1996, Massachusetts enacted interstate banking laws in response to the
Riegle-Neal Act. The laws permit, subject to certain deposit and other
limitations, interstate acquisitions, mergers and branching on a reciprocal
basis. The Riegle-Neal Act has made it easier for out-of-state institutions to
attempt to purchase or otherwise acquire a Massachusetts bank, or to compete
with the Bank in Massachusetts, and similarly has made it easier for the Bank to
compete outside the state.

     Gramm-Leach-Bliley Act of 1999. The general effect of the new law is to
establish a comprehensive framework to permit affiliations among commercial
banks, insurance companies, securities firms, and other financial service
providers by revising and expanding the Bank Holding Company Act framework to
permit a holding company system, such as Andover, to engage in a full range of
financial activities through a new entity known as a "financial holding
company." "Financial activities" is broadly defined to include not only banking,
insurance, and securities activities, but also merchant banking and additional
activities that the Federal Reserve Board, in consultation with


                                       8
<PAGE>   15


the Secretary of the Treasury, determines to be financial in nature, incidental
to such financial activities or complementary activities that do not pose a
substantial risk to the safety and soundness of depository institutions or the
financial system generally. Generally, the Gramm-Leach-Bliley Act does the
following: (i) repeals historical restrictions on, and eliminates many federal
and state law barriers to, affiliations among banks, securities firms, insurance
companies, and other financial service providers; (ii) provides a uniform
framework for the functional regulation of the activities of banks, savings
institutions, and their holding companies; (iii) broadens the activities that
may be conducted by national banks (and derivatively, state banks), banking
subsidiaries of bank holding companies, and their financial subsidiaries; (iv)
provides an enhanced framework for protecting the privacy of consumer
information; (v) adopts a number of provisions related to the capitalization,
membership, corporate governance, and other measures designed to modernize the
Federal Home Loan Bank system; (vi) modifies the laws governing the
implementation of the Community Reinvestment Act of 1977; and (vii) addresses a
variety of other legal and regulatory issues affecting both day-to-day
operations and long-term activities of financial institutions. In order to
engage in the new activities, a bank holding company, such as Andover, must meet
certain tests and elect to become a financial holding company. Specifically, all
of a bank holding company's banking subsidiaries must be well-capitalized and
well-managed, as measured by regulatory guidelines, and all of the bank holding
company's banks must have been rated "satisfactory" or better in their most
recent CRA evaluation. Furthermore, a bank holding company that elects to be
treated as a financial holding company may face significant consequences if its
banks fail to maintain the required capital and management ratings, including
entering into an agreement with the Federal Reserve Board that imposes
limitations on its operations and may even require divestitures. Such possible
ramifications may limit the ability of a bank subsidiary to significantly expand
or acquire less than well-capitalized and well-managed institutions. At this
time, Andover has not determined whether it will become a financial holding
company.

     Further, the Gramm-Leach-Bliley Act includes a new section of the Federal
Deposit Insurance Act governing subsidiaries of state banks that engage in
"activities as principal that would only be permissible" for a national bank to
conduct in a financial subsidiary. The provision will permit state banks, to the
extent permitted under state law, to engage in certain new activities which are
permissible for subsidiaries of a financial holding company. Further, it
expressly preserves the ability of a state bank to retain all existing
subsidiaries. Massachusetts permits Massachusetts-chartered banks to engage in
activities which are permissible for national banks and that are approved by the
Commissioner. Thus, the Bank would only be permitted to engage in the activities
authorized by the Gramm-Leach-Bliley Act that are also approved by the
Commissioner or otherwise authorized by Massachusetts law. In order to form a
financial subsidiary, a state bank must be well-capitalized, and the state bank
would be subject to certain capital deduction, risk management and affiliate
transaction rules which are applicable to national banks.

EMPLOYEES

     At December 31, 1999, Andover had 281 full-time equivalent employees. None
of the employees of Andover are represented by a collective bargaining group and
management considers relations with its employees to be good.

SUBSIDIARIES

     Andover has one direct subsidiary, the Bank. The Bank has two wholly-owned
subsidiaries and one majority-owned subsidiary. One of the Bank's subsidiaries,
AB Insurance Services LLC, was created in 1999 to act as an insurance agent or
broker enabling it to sell all lines of consumer and commercial insurance. The
Bank's other direct subsidiary, ASB Development Corp. ("ASB"), has five
subsidiaries and holds title to a portion of Andover's main office, the loan
operations building and to other income producing property. One subsidiary of
ASB holds real estate property that comprises a portion of Andover's main office
location. Three other subsidiaries of ASB were organized as Massachusetts
security corporations to take advantage of beneficial state tax treatment
related to the holding of certain investments. The fifth subsidiary of ASB,
Andover Preferred Capital Corporation ("APCC"), is 99 percent owned by ASB and
is a Massachusetts business corporation which has elected to be taxed as a real
estate investment trust for federal and Massachusetts tax purposes. APCC holds
mortgage loans which were previously originated by Andover Bank. The
majority-owned subsidiary of the Bank, Andover Capital Group, Inc., provides
secured equipment lending and lease financing.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

     General. The Company's results of operations depend to a great extent on
the Bank's net interest income, which is the difference between income earned on
the loan and investment portfolios and the interest paid by the Bank on deposits
and borrowed funds, the size of the provisions or credits for loan losses and
operating expenses. Net interest income is primarily affected by the level of
earning assets as a percentage of total assets, the level of interest-bearing
liabilities, yields earned on assets and rates paid on liabilities. Earnings are
also affected by non-interest income which consists primarily of mortgage
banking income, transaction account fees, gains and losses on sales of the
investment portfolio and real estate operations. The levels of operating
expenses and income taxes also affect earnings.

     On June 30, 1999, the Company merged Andover Bank NH with and into Andover
Bank with the two banking offices of Andover Bank NH remaining in full operation
as branches of Andover Bank.

     The following is a discussion and analysis of the Company's consolidated
results of operations for the last three years and its financial condition at
the end of fiscal 1999 and 1998. This section is intended to be read in
conjunction with the Consolidated Financial Statements and accompanying
footnotes.

     The following also contains forward-looking statements. There are a number
of important risks, uncertainties and other factors that could cause the
Company's actual results, performance or achievements to differ materially from
those expressed or implied by such forward-looking statements. These risks,
uncertainties and other factors include, without limitation, those set forth
under the caption "Certain Factors That May Affect Future Results".

RESULTS OF OPERATIONS

     Andover generated net income of $18.9 million or $2.82 per diluted share,
$17.4 million or $2.60 per diluted share and $13.2 million or $1.99 per diluted
share in 1999, 1998 and 1997, respectively. Andover's return on average assets
increased in 1999 to 1.31%, as compared to 1.27% in 1998 and 1.06% in 1997.
Return on average stockholders' equity decreased in 1999 to 15.05%, as compared
to 15.64% in 1998 and 13.24% in 1997. The Company's financial performance in
1999 includes a pre-tax gain of $1.6 million from the termination of the
Company's defined benefit pension plan, increased mortgage banking income and an
increase in net interest income. The Company's financial performance in 1998 was
positively impacted by a credit for loan losses of $1.7 million and an increase
in net interest income. The financial performance in 1997 was impacted by an
increase in total earning assets as well as the net yield on those assets.

     Net Interest and Dividend Income. Net interest and dividend income was
$47.3 million in 1999, $42.2 million in 1998 and $38.7 million in 1997. Net
interest income increased $5.1 million in 1999, $3.5 million during 1998 and
$3.4 million during 1997, primarily due to higher average earning asset volumes
in each of the years. Market interest rates have been fairly volatile over the
past several years. During 1999, market interest began to rise in the spring and
continued to rise throughout the year. The Company was able to hold the rates
paid on deposits during 1999 in spite of the market rate increase, the effect of
which allowed the interest rate spread to widen to 2.79% and the net yield to
increase to 3.37% in 1999. During 1998, the difference between longer-term
interest rates and shorter-term interest rates lessened, thereby creating a flat
yield curve. This compression in the margins was reflected in the declines in
both the interest rate spread of 2.57% and the net yield of 3.18% for 1998. In
1997, the interest rate spread of 2.67% and the net yield of 3.22% were
favorably impacted by market interest rates. The amount of foregone interest
income from nonaccruing and restructured loans totaled $256,000 in 1999,
$514,000 in 1998 and $716,000 in 1997.

     Average earning assets increased 5.9% in 1999 to $1,404.3 million as of
December 31, 1999, and increased 10.5% during 1998 to $1,326.5 million. The
increase in each of the two years was primarily due to higher loan growth
resulting from increased loan originations and purchases.

     The volatility in the interest rates has also impacted the yields earned on
the investment portfolio. The yield on short-term investments decreased 29 basis
points during 1999 to 5.02%, while also decreasing 14 basis points during 1998
to 5.31%. The yields earned on investment securities decreased 32 basis points
in 1999 to 6.36% as compared to 6.68% in 1998 and 1997. The yield on
mortgage-backed securities decreased 9 and 22 basis points during 1999 and 1998,
respectively, to 6.52% and 6.61%, respectively. In the latter part of 1999,
there were three increases in the federal funds rate totaling 75 basis points.
During 1998, there were three decreases in the federal funds rate totaling 75
basis points while there was an increase of 25 basis points in 1997. The swings
in the federal funds rate have impacted the short-term investment yield in a
corresponding manner. The decline in the yield on mortgage-backed securities
reflects the decline in long-term interest rates since the cash flows generated
by the high prepayment activity were unable to be reinvested at a comparable
interest rate.

     Total average loans increased $71.5 million during 1999 and $118.7 million
during 1998 primarily due to retained loan originations and whole loan
purchases. The yield on real estate loans decreased 19 basis points in 1999 to
7.26% while decreasing 31 basis points during 1998 to 7.45%. The largest
component of the yield on real estate loans was residential loans. Due to the
compression in the yield curve in 1998, the biggest impact has been felt in the
residential portfolio as evidenced by the 27 and 35 basis point decline,
respectively, in the average yield during 1999 and 1998. The yields on the
commercial real estate and construction and land portfolios have declined
slightly over the past two years. The yield on consumer loans decreased 55 basis
points in 1999 to 7.94% and increased 29 basis points in 1998 to 8.49%. The
impact of the declines in the prime rate in the fourth quarter of 1998 was felt
in 1999. The yield on commercial loans decreased 101 basis points in 1999 to
8.05% and decreased 38 basis points during 1998 to 9.06%. The decline in the
yield on commercial loans reflects a decline in the prime rate as well as
competitive pricing pressures. In addition, the yield on the lease financings,
included in the commercial portfolio, was lower than the portfolio, thereby
dragging down the overall yield.

     The rate paid on interest-bearing deposits decreased 56 basis points in
1999 to 3.92%, and decreased 14 basis points during 1998 to 4.48%. Core
deposits, which include NOW, savings and money market accounts, typically have
rates lower than those paid on certificates of deposit. However, to grow the
core deposit balances, the Bank has offered promotional rates on certain
products. While the Bank reduced the rates in 1998 in connection with a decline
in market interest rates, the impact of the rate reduction was felt in 1999. The
impact of the promotional rates on the savings rate has been an increase of 21
basis points in 1998 and 98 basis points in 1997. Average balances on these
savings accounts, meanwhile, have grown by $34.0 million and $54.6 million,
respectively, in 1999 and 1998. The Bank moderated the rates it paid on money
market accounts and had a decrease in the rate paid of 8 and 14 basis points,
respectively, in 1999 and 1998. However, the balances maintained in money market
accounts have declined in each of those years as customers have migrated to the
savings account promotional products. The balances maintained in NOW accounts
have increased modestly in both years while the rates have remained fairly
stable during that same time period. Certificate of deposit average balances
decreased $37.0 million and $7.6 million, respectively, and the rates paid
decreased 62 and 8 basis points, respectively, during 1999 and 1998. The decline
in the average balances and rates paid on the certificates of deposit reflect
the customers' desire to migrate out of longer-term deposits into core deposit
or short-term maturities.

     The Company has continued its reliance on borrowed funds as an alternative
source of funds to deposits in order to grow average earning assets. During
1999, the average balance of borrowed funds increased $59.3 million while the
rate paid decreased 25 basis points. In 1998, the average balance of borrowed
funds increased $44.2 million while the rate paid decreased 17 basis points. The
Company's reliance on shorter term borrowed funds in 1999 allowed it to keep the
rates paid on its borrowed funds low in spite of the overall increase in market
rates. The decline in the rate paid on borrowed funds in 1998 was due to the
reduction in overall market interest rates.

     The combination of the factors mentioned above contributed to a 22 basis
point increase to 2.79% in the interest rate spread in 1999 and a 10 basis point
decline in the interest rate spread to 2.57% during 1998. The net yield on
earnings assets was 3.37% for the year ended December 31, 1999 and 3.18% and
3.22%, respectively, for 1998 and 1997.

     Rate/Volume Analysis. The following table shows the changes in interest
income and interest expense caused by changes in the volume of interest earning
assets and interest bearing liabilities, and changes in interest rates received
and paid, respectively. The change attributable to a mix of volume and rate has
been allocated proportionally to the change due to volume and the change due to
volume and the change due to rate.

     Provision (Credit) for Loan Losses. The allowance for loan losses is
established through a provision for loan losses charged to the statement of
operations. The allowance is reduced by a credit for loan losses as well as loan
charge-offs. Assessing the adequacy of the allowance for loan losses involves
substantial uncertainties and is based upon management's evaluation of the
amounts required to meet possible losses in the loan portfolio after weighing
various factors. Among the factors management may consider are the quality of
specific loans, risk characteristics of the loan portfolio generally, the level
of nonaccruing loans, current economic conditions, trends in delinquencies,
actual charge-off experience, and the collateral values of the underlying
security. Ultimate loan losses may vary significantly from current estimates and
future additions may be necessary. In addition, various regulatory agencies, as
an integral part of their examination process, review the Bank's allowance and
may require the Bank to provide additions to the allowance based on their
assessment, which may differ from management's assessment.


                                       16
<PAGE>   23


     The provision for loan losses in 1999 and 1997 was $400,000 and $983,000,
respectively, as compared to a credit for loan losses in 1998 of $1.7 million.
Net recoveries amounted to $498,000 in 1999, while net charge-offs totaled
$330,000 in 1998 and $691,000 in 1997. The provision for loan losses of $400,000
in 1999 was taken in the fourth quarter due to the fact that almost half of the
corporate loan growth occurred in the fourth quarter, which when combined with
the sudden deterioration of two lease financing relationships, necessitated the
charge to earnings. The credit for loan losses in 1998 resulted from an
improvement in overall loan quality, as reflected by the 59% decline in
nonaccruing loans, 38% decline in total overdue loans and net charge-offs of
$330,000. The decline in the provision recorded in 1997 from 1996 reflects,
among other things, a 33% reduction in non-performing assets and reduced levels
of delinquencies, combined with lower levels of net charge-offs.

     While management believes that it has been reasonable in its analysis of
the allowance for loan losses and in estimating the net fair values of other
real estate owned, management is unable to predict the ultimate course of the
economy or the extent of its impact on the Company's financial condition. See
"Financial Condition -- Risk Elements" and Notes 1 and 4 to the "Consolidated
Financial Statements".

     Non-interest Income. The Company recorded income from non-interest sources
of $4.2 million in both 1999 and 1998 and $4.8 million in 1997. The increase of
$54,000 in 1999 resulted from an increase of $1.3 million in mortgage banking
income offset by losses from the sales of assets held for sale and investments
available for sale. The decrease in 1998 was primarily due to losses relating to
mortgage banking activities, offset by gains on real estate operations and
increased fee income on deposits and loans.

     Net losses from sales and redemptions of investments totaled $385,000 in
1999, compared to net gains of $17,000 in 1998 and $158,000 in 1997. In the
third quarter of 1999, approximately $27.6 million of lower yielding investments
available for sale were sold at a loss of $385,000. The reinvestment of the
sales proceeds was intended to enhance future earnings. See "Financial Condition
- -- Investments" and Notes 1 and 3 to the "Consolidated Financial Statements".

     The Company recorded net gains from sales of assets held for sale of
$17,000 in 1999, $653,000 in 1998 and $264,000 in 1997. Included in each of the
three years were gains totaling $439,000, $726,000 and $447,000, respectively,
from the capitalization of originated mortgage servicing rights. See "Financial
Condition -- Loans" and Notes 1, 2 and 5 to the "Consolidated Financial
Statements".

     Andover may incur gains and losses on the sale of the loans that it
originates. These loans are generally securitized prior to sale in the form of
mortgage-backed securities which are guaranteed by a government agency and are
then held for sale. Because loans held for sale are stated at the lower of cost
or market value and mortgage-backed securities held for sale are stated at fair
value, periods of rising interest rates, such as was experienced in 1999, cause
the values of loans and mortgage-backed securities held for sale to decrease,
resulting in a charge to income. The Company frequently enters into forward
delivery contracts to reduce its exposure to this risk from rising interest
rates. Forward delivery contracts may, however, increase exposure to the risk
from declining interest rates if sufficient loans or mortgage-backed securities
held for sale bearing interest rates specified by the contracts are not
available to meet the delivery schedules under the contracts. See Note 17 to the
"Consolidated Financial Statements".

     Mortgage banking income represents the gross servicing fee income less
amortization and provisions or credits for the valuation allowance on the
mortgage servicing assets. The Company retains as a service fee a portion of the
interest paid by the borrower. A valuation allowance for mortgage servicing
assets was established in 1996. A credit to the valuation allowance was recorded
in 1999 totaling $175,000, as compared to provisions charged against earnings
totaling $1.5 million and $285,000, respectively, for the years ended December
31, 1998 and 1997. In a low interest rate environment, the underlying
residential loans will repay faster than expected, causing the fair value of the
mortgage servicing assets to decline as well as reduce the gross cash flows
collected on a shrinking serviced portfolio. This prepayment risk results in
increased provisions and charge-offs to the valuation allowance, and thus lower
mortgage banking income.


                                       17
<PAGE>   24


     Mortgage banking income totaled $908,000 in 1999, as compared to a mortgage
banking loss of $389,000 in 1998 and income of $2.0 million in 1997. The
increase in income in 1999 was mainly due to the change in fair values caused by
higher market interest rates, thereby enabling the Company to record a credit to
the valuation allowance. The gross servicing income has fluctuated over the past
three years but generally corresponds to the level of average loans serviced for
investors.

The table below summarizes the Company's results from servicing loans for
investors.

</TABLE>

     During 1999, 1998 and 1997, the Company purchased mortgage servicing rights
to $223.2 million, $184.7 million and $228.8 million, respectively, in
residential first mortgage loans. These purchased balances are included in the
balance of loans serviced for investors. As part of its long-term business plan,
the Company intends to continue purchasing mortgage servicing rights to
maintain, or even increase, the use of its existing servicing capacity as well
as increase non-interest income when it is deemed appropriate. The Company also
expects to continue selling mortgages in the secondary market while retaining
the servicing rights, therefore, servicing income related to this activity is
accordingly expected to continue for the foreseeable future. See Notes 1 and 5
to the "Consolidated Financial Statements".

     Losses on real estate operations totaled $5,000 in 1999, versus gains of
$14,000 in 1998, compared to losses of $971,000 in 1997. Real estate operations
consist of provisions for the valuation allowance caused by declines in net fair
value, operating costs of maintaining other real estate owned, gains or losses
on sales of properties and costs associated with the foreclosure on nonaccrual
properties, less any rental income on other real estate owned. The Company
accounts for other real estate owned at the lower of cost or estimated net fair
value. Declines in value subsequent to foreclosure or substantive repossession
result in a charge to the valuation allowance.

     In 1999 and 1998, credit provisions were taken to reduce the valuation
allowance in the amount of $20,000 and $107,000, respectively, while
replenishing the valuation allowance resulted in a charge of $350,000 in 1997.
Gains on sales of other real estate owned totaled $52,000 in 1999, $50,000 in
1998 and $110,000 in 1997. The costs of foreclosing on loans, as well as the
administrative costs of maintaining the non-performing assets, correspond with
the average volumes of problem assets and totaled $92,000 in 1999, $153,000 in
1998 and $757,000 in 1997. See "Financial Condition -- Risk Elements" and Note 1
to the "Consolidated Financial Statements".

     Other income totaled $3.7 million, $3.9 million and $3.3 million in 1999,
1998 and 1997, respectively, and was derived primarily from customer service
charges and fees. Deposit account service charges, representing the largest
component of such other income, totaled $2.5 million in 1999, $2.3 million in
1998 and $2.0 million in 1997. Loan late charges and other fees decreased during
1999 by $201,000 to $502,000, while increasing in 1998 to $703,000 and remaining
stable in 1997 at $407,000, respectively. The majority of the increase in
deposit fee income in each of the two years is due to increased ATM fee income.
As customers increasingly use debit cards or non-customers use the Bank's
multiple ATM's, overall fee income has increased. The swings in the loan fee
income reflect the changes in the residential loan originations which increased
tremendously in 1998 and then decreased in 1999. Another source of income that
has remained stable in each of the three years is rental income. Other income
totaled $432,000, $577,000 and $559,000, respectively, for 1999, 1998 and 1997
and includes income from Liberty Securities, IRA, safe deposit and miscellaneous
charges. See Note 13 to the "Consolidated Financial Statements".

     Non-interest Expense. Non-interest expenses decreased $600,000 or 2.7% to
$22.0 million in 1999 while increasing $591,000 or 2.7% to $22.6 million in
1998. The decrease in 1999 was primarily due to the curtailment and settlement
gains of $1.6 million on terminating the Company's defined benefit plan. The
modest increase in 1998 reflects higher salary costs due to merit increases
partially offset by a higher level of capitalized loan origination costs
resulting from the high level of originations as well as the Company's continued
attempts at cost containment.

     Salaries and employee benefits, the largest component of non-interest
expense, decreased $893,000 to $11.1 million in 1999 and increased $123,000 in
1998 to $12.0 million. The decrease in 1999 resulted from the aforementioned
gains of $1.6 million from the termination of the Company's defined benefit
pension plan which were reflected as a reduction of salary and employee
benefits. Offsetting these gains, however, were increased costs for higher staff
levels, merit increases and employee benefits. The increase in 1998 was
primarily due to increased benefits offset by higher levels of capitalized loan
origination costs. See Note 14 to the "Consolidated Financial Statements".

     Office occupancy and equipment increased $195,000 to $3.2 million in 1999
and increased $87,000 in 1998 to $3.0 million. The increase in 1999 was
primarily due to increased depreciation costs on equipment purchases and high
expenses on the Company's leased properties. The increase in 1998 was primarily
due to increased rental expense resulting from rental increases and more
properties leased from third parties. See Note 6 to the "Consolidated Financial
Statements".

     Data processing expenses totaled $2.4 million in 1999, $2.1 million in 1998
and $1.9 million in 1997. Data processing expenses increased $289,000 in 1999
and $157,000 in 1998 due to a higher loan and deposit base resulting from the
purchase of loans and mortgage loan servicing and internally generated loan
growth. In addition, the introduction of alternative delivery systems, via
customers' computers, debit cards and by the telephone service center, have
caused overall processing costs to increase in each of the two years. The level
of data processing expenses incurred in 1999 on behalf of the Company's effort
in its Y2K compliance was approximately $70,000. See "Financial Condition - -
Year 2000 Readiness Disclosure".

     Professional fees, including corporate legal and accounting and auditing
expenses, totaled $1.2 million in 1999, $940,000 in 1998 and $862,000 in 1997.
Professional fees increased $238,000 in 1999 due to increased recruiting
expenses and consulting fees. Professional fees increased $78,000 in 1998 due to
increased consulting and corporate legal expenses.

     Marketing expenses totaled $908,000 in 1999, $831,000 in 1998 and $988,000
in 1997. Marketing expenses increased $77,000 in 1999, due to an increase in
discretionary promotions while expenses decreased $157,000 in 1998 due to a
reduction in the number of discretionary promotions and direct mail
solicitations.

     Mortgage banking expenses totaled $267,000 in 1999, $606,000 in 1998 and
$430,000 in 1997. Costs included in mortgage banking expenses are commissions
and related expenses paid to the mortgage loan originators, net of any deferred
origination expenses, and costs associated with servicing the portfolio for
outside investors. The swing in expenses in each of the two years reflect the
level of origination volume.

     Other operating expenses totaled $3.0 million in 1999, $3.1 million in 1998
and $3.0 million in 1997. Some of the cost savings in 1999 result from the
combination of the two subsidiary banks as well as a continued focus on cost
containment. The Company has experienced some savings in the area of corporate
insurance and telephone expenses. The increase of $127,000 in 1998 was
distributed among multiple categories and generally reflected costs associated
with running a larger organization.

     Federal and State Income Tax Expense. The Company recorded tax expenses of
$10.3 million, $8.2 million and $7.3 million in 1999, 1998 and 1997,
respectively, and realized effective tax rates of 35%, 32% and 36%,
respectively. The income tax expense increase of $2.1 million in 1999 resulted
from an increase in pre-tax income of 14.2% offset by tax benefits of $440,000.
The increase in 1998 was primarily due to an increase in pre-tax income of $5.1
million offset by a $1.1 million tax benefit resulting from the favorable
resolution of several tax


                                       19

issues that had previously been fully reserved against. Recognition of deferred
tax assets and liabilities is based on the expected future tax consequences of
temporary differences between the financial reporting and tax basis of the
Company's assets and liabilities. Measurement of deferred tax assets and
liabilities is based upon the provision of enacted tax laws and the effects of
future changes in tax laws or rates.

     Management believes the existing net deductible temporary differences that
give rise to the net deferred income tax asset will reverse in periods in which
the Company generates net taxable income. For the years ending December 31,
1999, 1998, and 1997, the Company generated taxable income of approximately
$27.0 million, $22.1 million and $17.3 million, respectively. Taxable income
differs from pretax book income primarily as a result of loan losses and
provision for losses on other real estate owned being recognized in a different
period than for book income. The Company recorded a reduction of the valuation
allowance of $328,000 in 1998 and $500,000 in 1997. The amount recognized in
1998 was due to the expiration of subsidiary net operating loss carry forwards
while the amounts recognized in 1997 were due to increased recoverable federal
income taxes.

     At December 31, 1999, the net deferred tax asset is supported by
recoverable income taxes of approximately $23.0 million. Management believes
that the net deferred income tax asset at December 31, 1999 will be realized
based upon the high level of taxable income in the past three years. It should
be noted, however, that factors beyond management's control, such as the general
state of the economy and real estate values, can affect future levels of taxable
income and that no assurance can be given that sufficient taxable income will be
generated to fully absorb gross deductible temporary differences.

     See Note 11 to the "Consolidated Financial Statements" for further
information.

FINANCIAL CONDITION

     Total assets increased $80.8 million, or 5.7%, to $1,491.1 million at
December 31, 1999. The growth in total assets was primarily due to an increase
of $82.3 million in total loans. Total assets at December 31, 1998 amounted to
$1,410.2 million, an increase of $87.5 million or 6.6% from $1,322.7 million at
December 31, 1997, resulting primarily from an increase in total loans of $71.9
million.

LOANS

     Total loans at December 31, 1999, prior to the allowance for loan losses,
amounted to $1,133.1 million compared with $1,050.8 million at December 31,
1998, an increase of $82.3 million or 7.8%, primarily due to internally
generated loan growth combined with purchases of $38.3 million in residential
and commercial real estate whole loans. As of December 31, 1999, 58.1% of
Andover's total loan portfolio consisted of loans with adjustable rates as
compared to 60.0% at December 31, 1998, reflecting the increased preference for
fixed rate loans by the Bank's corporate customers.

     Total real estate loans, which represent the largest component of the loan
portfolio, increased $54.2 million in 1999 to $1,014.8 million at December 31,
1999, due to real estate loan originations of $295.1 million. Origination
volumes are sensitive to market rates, particularly in the residential loan
refinancing arena. As can be determined by the following table, total loan
originations were the highest in 1998, a year with low interest rates throughout
the year. At the start of 1999, low interest rates prevailed but in the spring
of 1999, market interest rates increased, a trend that continued through the
year. However, total loan originations were strong in each of the other years
but the mix between retail and corporate originations changes in relation to the
level of mortgage refinance activity.

The following table shows the composition of the Company's loan originations and
loan purchases for the years indicated:

     Residential loan originations totaled $173.8 million in 1999, $329.4
million in 1998 and $165.3 million in 1997. It should be noted that these
originations are not fully reflected in loan balances outstanding due to the
securitization, regular amortization and prepayments of residential real estate
loans as well as refinancings and the sale of a portion of new loan production.
As mentioned above, the originations of residential loans are sensitive to
market interest rates and 1998 experienced extremely high levels of
refinancings.

     The majority of the Company's residential loans are underwritten to be
eligible for sale in the secondary market. Andover sells most of the eligible
30-year fixed rate loans it originates. A loan which the Company intends to sell
may be sold directly or converted into mortgage-backed securities and sold in
that form. Residential loans sold directly amounted to $1.4 million in 1999,
$6.1 million in 1998 and $3.4 million in 1997. Those sold in the form of
mortgage-backed securities held for sale or available for sale totaled $32.3
million, $53.3 million and $24.2 million, respectively, in 1999, 1998 and 1997.
The portfolio of residential mortgage loans serviced for others totaled $956.4
million at December 31, 1999, compared to $894.4 million at December 31, 1998
and $971.0 million at December 31, 1997.

     Commercial real estate loans increased $43.4 million in 1999 to $207.4
million at December 31, 1999, while construction and land loan balances
increased $7.1 million to $63.7 million in the same period. Outstanding
commercial loans increased $28.2 million in 1999 to $56.5 million at December
31, 1999. While originations of corporate loans, comprised of commercial real
estate, commercial, construction and land loans and lease financings, are
sensitive to the interest rate environment; a customer's capacity for borrowing,
real estate values and current and anticipated economic conditions have a more
critical role. Origination volumes for these loan types have increased
substantially in 1999, reflecting increasing real estate values, higher capacity
for borrowings, as well as the Company's continued interest in corporate
lending. Total originations of corporate loans were $177.3 million in 1999,
$153.9 million in 1998 and $84.1 million in 1997. Not all originations reflect
the balances advanced at the time of origination due to amounts available for
future commitments, nor does it reflect the level of prepayments experienced in
the corporate loans.

     Commercial real estate, construction and land, commercial loans and lease
financings involve significant risks compared with single-family residential
mortgage and consumer lending. See Item 1, "Business -- Lending Activities".

     Consumer loans outstanding decreased modestly to $61.8 million at December
31, 1999, and decreased $6.4 million in 1998. A large component of the decline
during 1998 resulted from the sale of student loans totaling $2.9 million. Over
the past four years, the Company has aggressively priced its home equity lines
of credit and second mortgage loans; thereby keeping originations of these loans
in excess of $20 million per year. Other consumer loans include collateral loans
and installment loans. Originations of consumer loans are also sensitive to
changes in the interest rate environment.

</TABLE>

     During 1999, continued progress was made in reducing non-performing assets
with a reduction of $995,000 or 28.5%, primarily due to a reduction of
nonaccruing loans. Loans transferred into other real estate owned totaled


                                       22
<PAGE>   29


$395,000, $773,000 and $2.1 million in 1999, 1998 and 1997, respectively The
impact of existing non-performing assets on future interest income will be
largely dependent upon converting these assets to earning status, either through
a return to performing status or through foreclosure and subsequent disposition
of the property.

     At December 31, 1999, total impaired loans were $2.5 million, of which $1.1
million had related allowances of $197,000 and $1.4 million which did not
require a related impairment allowance. All of the $2.5 million in impaired
loans have been measured using the fair value of the collateral method. During
the year ended December 31, 1999, the average recorded value of impaired loans
was $2.1 million and the related amount of interest income recognized was
$40,000.

     See Notes 1 and 4 to the "Consolidated Financial Statements" for further
information.

     Nonaccruing Loans. Management places loans, regardless of collateral
values, on nonaccrual status when principal or interest is past due 90 days or
more. All previously accrued but uncollected interest is reversed against
current period interest income when a loan is placed on nonaccrual status. Loans
for which payments are less than 90 days past due are placed on nonaccrual
status when concern exists as to the ultimate collection of principal or
interest. Non-performing loans are generally not returned to performing status
until the obligation is brought current and when concern no longer exists as to
the collectibility of principal or interest.

</TABLE>

     During 1999, loans on nonaccrual decreased 24.2% to $2.5 million,
throughout most loan categories. Interest income of approximately $477,000 would
have been recorded in 1999 on nonaccruing loans if those loans had been on a
current basis in accordance with their original terms. Interest income actually
recognized in 1999 on nonaccruing loans amounted to approximately $159,000.
Additionally, another $62,000 in interest payments were received on nonaccruing
loans during 1999 and applied as a reduction of the loan balance instead of as
interest income.

     Restructured Loans. A restructured loan is one for which the Bank has
modified the terms to provide a temporary reduction in the rate of interest
below the prevailing market interest rates at the time of modification and, in
most instances, an extension of payments of principal or interest or both due to
the deterioration in the financial position of the borrowers. Restructured loans
are not returned to performing status until the obligation has performed for a
reasonable period of time, its ultimate collectibility is no longer in doubt and
is at a market rate of interest. Restructured loans totaled $413,000 at December
31, 1999.

     Other Real Estate Owned. Andover's other real estate owned has consistently
declined over the last several years as economic conditions improved. The
valuation allowance represents management's estimate of the net fair value of
other real estate owned.

     All other real estate owned is carried at the lower of the carrying value
of the loan or the net fair value of the property. Initial writedowns to net
fair value are charged to the allowance for loan losses and totaled $104,000 in
1999, $172,000 in 1998 and $836,000 in 1997. In 1999 and 1998, credit provisions
were taken to reduce the valuation allowance in the amount of $20,000 and
$107,000, respectively. Subsequent provisions due to deterioration in real
estate values are charged to real estate operations and totaled $350,000 in
1997. Gains of $52,000, $50,000 and $110,000 were recognized on sales of
$678,000, $1.1 million and $3.2 million in other real estate owned in 1999, 1998
and 1997, respectively.

     The allowance for loan losses as a percentage of total loans remained
stable at 1.0% at both December 31, 1999, and December 31, 1998, as compared to
1.3% at December 31, 1997. While the Company has experienced four years with
loan recoveries in excess of $1.1 million each, this trend is not expected to
continue. Management analyzes the adequacy of the allowance for loan losses on a
quarterly basis. See "Results of Operations -- Provision for Loan Losses".
Management measures the adequacy of its allowance for loan losses by assigning
loans into risk categories based on a loan classification system modeled after
the bank regulatory classification system. While management believes that its
allowance for loan losses is adequate to cover possible losses, there are
uncertainties regarding future events. Deterioration in the real estate market
or economy may result in additions to nonaccruing loans, charge-offs or
provisions for loan losses to maintain an adequate allowance. In addition,
various regulatory agencies, as an integral part of their examination process,
periodically review the Bank's allowance for loan losses. Such agencies may
require the Bank to provide additions to the allowance based on their judgments
about information available to them at the time of their examination. Allocation
of the allowance for loan losses to the various categories of the portfolio is
also made periodically, based on management's judgment in weighing various
factors, including the quality of specific loans, the level of nonaccruing loans
in the various categories, current economic conditions, trends in delinquencies
and prior charge-offs, and the collateral value of the underlying security.
Because the allowance for loan losses is based on various estimates, including
loan collectibility and real estate values, and includes a high degree of
judgment, subsequent changes in the general economic prospects of the borrowers
may require changes in those estimates.

     The changes in the allowance allocated to each category of loan directly
corresponds to the level of nonaccrual loans and adversely classified loans as
well as the level of outstanding loans. Andover historically has experienced
lower losses in its residential mortgage loan portfolio and, therefore,
allocations applicable to this portfolio are lower.

     The following table summarizes the allocation of the allowance for loan
losses at December 31:

INVESTMENTS

     Andover's investment portfolio totaled $286.7 million as of December 31,
1999, and $283.0 million as of December 31, 1998. The Company manages the
investment portfolio in accordance with an investment policy adopted by the
Board of Directors. The primary objectives are to provide interest and dividend
income, to ensure adequate liquidity and achieve an acceptable asset/liability
gap position while diversifying the asset mix. The investment portfolio is also
evaluated in comparison to returns that are earned by the loan portfolio.


                                       25

     During the third quarter of 1999, approximately $27.6 million of lower
yielding investments were sold at a loss of $385,000. These included U.S.
government obligations and GNMA mortgage-backed securities. The reinvestment of
the sales proceeds was intended to enhance future earnings.

     The principal component of the total investment portfolio is
mortgage-backed securities, which accounted for 43.0% of total investments at
December 31, 1999. The remaining portion of the total investment portfolio
consists of U.S. government and federal agency obligations, corporate bonds,
short-term investments, equity securities and other investment grade securities.
Corporate bonds represent the fastest growing component of the investment
portfolio and totaled 30.6% as of December 31, 1999, as compared to 14.9% at
year end 1998.

     All of the mortgage-backed securities represent undivided interests in
pools of mortgages which have been formed into pass-through securities and sold
to investors by GNMA, FHLMC and FNMA. Securities issued by GNMA, a wholly-owned
U.S. government corporation, are fully guaranteed as to the timely payment of
principal and interest. Securities issued by FHLMC and FNMA, government
sponsored corporations, carry each corporation's guarantee as to the timely
payment of interest and the ultimate payment of principal. Cash flows from the
underlying mortgages of all mortgage-backed securities are passed through to
Andover in the form of monthly payments of interest, scheduled principal
amortization, and prepayments of mortgage balances. These securities, therefore,
have unpredictable cash flows. Principal repayments on all mortgaged-backed
securities in the investment portfolio totaled $54.4 million in 1999 as compared
to $60.4 million in 1998, reflecting, among other things, the slowdown in the
mortgage refinance market. The approximate market value of adjustable rate
mortgage-backed securities included in the investment portfolio totaled $11.6
million at December 31, 1999, as compared to $41.1 million at December 31, 1998,
primarily due to the sale of investments mentioned above.

     The carrying amount of callable securities included in investments
available for sale and investments held to maturity totaled $45.9 million and

     Debt securities are classified as held to maturity only when there is
positive intent and ability to hold them to maturity. Such securities are
recorded at amortized cost. Trading securities are debt and equity securities
held principally for the purpose of selling in the near term. The Company does
not have any securities designated as trading securities. Such securities are
recorded at fair value, with unrealized gains and losses recorded in earnings.
Investments available for sale are any debt or equity security not classified as
either held to maturity or trading securities. Investments available for sale
are recorded at fair value with any changes in fair value recorded as a separate
component of stockholders' equity, net of related income taxes.

     See Notes 1, 2 and 3 to the "Consolidated Financial Statements" for further
information.

     There was a fair value decline of $9.8 million in the investment portfolio,
from a net unrealized gain of $3.7 million at December 31, 1998 to a net
unrealized loss of $6.2 million at December 31, 1999, resulting from a
significant increase in market interest rates. Changes in interest rates and
their impact on the unrealized gain or loss in the investment portfolio are not
material factors in the Company's overall investment strategy. This is largely
due to the fact that neither the changes nor their impact can be controlled by
the Company. Additionally, investment purchases are often funded by long-term
advances of an equivalent term in order to achieve a consistent spread on a
particular investment.

     The following table presents unrealized gains and losses by major
categories of securities at December 31, 1999. The net unrealized losses of $5.0
million on investments available for sale is included in stockholders' equity,
net of applicable income taxes at December 31, 1999. At that date, Andover's net
unrealized losses on investments held to maturity amounted to $1.2 million.

DEPOSITS

     Total deposits decreased $20.1 million during 1999 to $968.5 million at
December 31, 1999, compared to an increase of $41.7 million during 1998. This
decrease was most pronounced in demand deposit accounts which decreased $16.2
million during 1999 although the balances increased $23.5 million in 1998. In
addition, certificates of deposit declined by $12.3 million during 1999. The
decline in 1999 and the increase in 1998 in demand deposits resulted from the
high level of custodial balances at year-end 1998 due to the high level of
mortgage refinance activity experienced at that time. The decline in
certificates of deposit balances reflect the continued customer preference for
shorter term or core deposit accounts without fixed maturities. Partially
offsetting these declines were increases in the savings account balances of
$14.0 million and $49.7 million in 1999 and 1998, respectively. The popularity
of these accounts were primarily due to the introduction of a tiered savings
product offering customers a premium rate on balances in excess of $50,000. This
premium product represents more than half of the savings account balances. The
decline in each of the past two years in money market accounts is primarily due
to a shift in customer preference for the premium savings account.

     See Note 8 to the "Consolidated Financial Statements" for further
information.

     The following table reflects the balance of deposit accounts of Andover at
each date indicated and the weighted average interest rates at December 31:

BORROWINGS

     Total borrowings increased $95.6 million in 1999 to $379.4 million at
December 31, 1999, and increased $25.1 million during 1998 to $283.8 million at
December 31, 1998. In order to fund the growth in total assets, the Bank has
increased its reliance on borrowed funds in 1999 due to the decline in total
deposits. The Bank will continue to


                                       29
<PAGE>   36


rely on borrowed funds as an alternative source of funds in order to grow
interest earning assets. The Bank has multiple sources for borrowed funds,
including its primary source, the FHLB of Boston.

     The weighted average rate on the total borrowed funds dropped to 5.31% at
December 31, 1999, from 5.39% at December 31, 1998. The decline in the weighted
average interest rate since year-end 1998 was due to a change in the mix of
borrowed funds and reflects the shorter term maturities at December 31, 1999.
Borrowed funds, maturing within one year or with an initial call date within one
year as of December 31, 1999, were approximately 81.4% as compared to 61.0% at
December 31, 1998. This reliance on shorter term borrowed funds in 1999 has
allowed the Company to keep the rates paid on its borrowed funds low in spite of
the overall increase in market interest rates.

     The amount of callable advances included in total borrowings totaled $125.0
million as of December 31, 1999. These advances are callable at the discretion
of the FHLB of Boston, starting in 2000 and at regular intervals thereafter.

See Notes 9 and 10 to the "Consolidated Financial Statements" for further

ASSET AND LIABILITY MANAGEMENT AND MARKET RISK

     The Bank's earnings are largely dependent on its net interest income, which
is the difference between the yield on interest-earning assets and the cost of
interest-bearing liabilities. The Company seeks to manage its exposure to
changes in interest rates, or market risk, through active monitoring and
management of its interest rate risk exposure. The policies and procedures for
managing both on and off balance sheet activities are established by Andover's
asset/liability management committee (ALCO). The Board of Directors reviews and
approves the ALCO policy annually and monitors its related activities on an
ongoing basis.

     Market risk is the risk of loss from adverse changes in market prices and
rates. The Bank's market risk arises primarily from interest rate risk inherent
in its lending and deposit taking activities.

     The main objective in managing interest rate risk is to minimize the
adverse impact of changes in interest rates on the Company's net interest income
and to preserve capital, while adjusting the Company's asset/liability structure
to obtain the maximum yield-cost spread on that structure. The Company relies
primarily on its asset/liability structure to control interest rate risk.
However, a sudden and substantial increase in interest rates may adversely
impact earnings to the extent that the interest rates borne by assets and
liabilities do not change at the same speed, to the same extent, or on the same
basis.

     The following two tables reflect different methods of disclosing the
Company's exposure to a change in interest rates and its potential impact on the
Company's net interest income. The gap analysis uses estimated prepayments,
contractual maturities and next repricing dates while the market risk analysis
excludes the next repricing dates. The interest rate sensitivity of the
Company's assets and liabilities in both tables would vary substantially if
different assumptions were used or if actual experience differs from the
assumptions provided.

     One method used to measure the interest rate risk exposure is the Company's
gap analysis, which involves comparing the difference between assets and
liabilities that mature or reprice during a given period of time. These
differences are a primary component of the risk to net interest income. A gap is
considered positive when the amount of interest sensitive assets exceeds the
amount of interest sensitive liabilities, and is considered negative when the
amount of interest sensitive liabilities exceeds the amount of interest
sensitive assets. A positive gap would produce increased net interest income
during a period of rising interest rates and decreased net interest income when
interest rates decline. A negative gap would have the reciprocal impact on net
interest income.

     The primary cause for the change in the Company's gap position from
December 31, 1998 to December 31, 1999, was the prepayment speeds used on the
residential loan and mortgage-backed securities portfolios from one year to the
next. This resulted in a negative gap position of 22.4% at December 31, 1999, as
compared to 9.3% at December 31, 1998.

     The balances on the interest sensitive asset and liability accounts have
been allocated among the various periods using common industry techniques and
market consensus data. Fixed and variable rate retail loans, the largest
component of the loan portfolio, are shown in the table in the time period
corresponding to scheduled principal amortization and anticipated prepayments
using annual conditional prepayment rates that vary from 11.1% to 18.0% at
December 31, 1999, as compared with 11.9% to 25.3% at December 31, 1998. In
addition, variable rate retail and corporate loans are allocated to the periods
in which the loans could be next adjusted. Fixed rate mortgage-backed securities
are allocated using annual conditional prepayment rates of 10.3% to 11.2% at
December 31, 1999, versus 21.2% to 46.9% at December 31, 1998. All other loans
and securities, certificates of deposit and borrowed funds are allocated to the
period in which the rates could be next adjusted or to their final contractual
maturity for the fixed rate instruments. Substantially all of the callable
advances from the FHLB are allocated according to their initial call dates due
to the strong likelihood of their being called by the FHLB given current market
interest rates. Other interest sensitive assets include assets held for sale and
FHLB stock. Nonaccruing loans have been excluded from both the gap analysis and
the market risk analysis.

     A substantial portion of the savings, money market and NOW accounts are
considered core deposits by management and, therefore, relatively insensitive to
interest rates. In addition, any future changes to the interest rates paid on
these accounts are at the sole discretion of management. Despite the foregoing
factors, these deposits


                                       31
<PAGE>   38


have been allocated between each time period based on the Bank's own historical
experience, or decay rates, in determining the deposit runoff.

     Another method used to measure interest rate risk is the market risk
analysis. The following table shows the Company's financial instruments that are
sensitive to changes in interest rates, categorized by expected maturity, and
the instruments' fair values at December 31, 1999.

</TABLE>


     Market risk sensitive instruments are generally defined as on and off
balance sheet derivatives and other financial instruments. Expected maturities
are contractual maturities adjusted for prepayments of principal. The Company
uses certain assumptions to estimate fair values and expected maturities. For
interest sensitive assets, expected maturities are based upon contractual
maturity, projected repayments and prepayments of principal using the same
ratios used for the gap analysis presented previously. However, as mentioned
above, the market risk analysis excludes repricing features on all interest
sensitive assets. Retail loans include residential and consumer loans while
corporate loans are comprised of commercial real estate, commercial,
construction and land loans and leases. For interest sensitive liabilities, the
same decay rates and contractual maturities used for the gap analysis are used
for the market risk analysis. The only difference between the gap analysis and
the market analysis of the interest sensitive liabilities are the callable
features on the FHLB advances. The market risk analysis uses the advances
contractual maturity date in all cases, whereas the gap report allocates the
callable advances using their respective initial call date.

</TABLE>

     Of the loans maturing after one year, $4.6 million, or 7.4%, have fixed
rates and $57.5 million, or 92.6%, have floating or variable rates.

LIQUIDITY

     The Company's primary source of funds is dividends from its bank
subsidiary. The Company could also access the capital market to raise additional
equity. Dividends from the Bank to the Company totaled $7.0 million in 1999,
$9.5 million in 1998 and $7.0 million in 1997.

     The Company made payments of dividends to stockholders in the amount of
$5.7 million, $4.5 million and $3.5 million, respectively, for the years ended
December 31, 1999, 1998 and 1997.

     The goal of the Company's liquidity management process is to assess funding
requirements so as to efficiently meet the cash needs of borrowers and
depositors, while also providing funds for attractive investment opportunities.
Liquidity involves the Company's ability to raise or gain access to funds in
order to fulfill its existing and anticipated financial obligations.

     The Bank has a diverse base of funding. Sources of liquidity include
maturation, amortization and prepayment of the investment and loan portfolios.
In addition, the Bank's investments available for sale portfolio provides the
Bank with flexibility to sell these securities quickly. Other sources of
liquidity are increasing deposit balances, funds purchased from other banks, the
sale of securities under repurchase agreements, customer repurchase agreements,
and borrowings from the FHLB, of which Andover Bank is a voluntary member. The
Bank may also obtain funds at the discount window of the Federal Reserve Bank of
Boston.

     At December 31, 1999, the Company had home equity, reserve credit and
commercial unadvanced lines of credit totaling $101.8 million. Outstanding
commitments to originate loans totaled $53.7 million. Unadvanced portions of
construction and land loans amounted to $26.5 million. Standby letters of credit
were $3.2 million. Loans sold with recourse totaled $1.2 million. Management
believes that its sources of liquidity are sufficient to meet these commitments
if and as called upon.

     See Notes 9, 10, 12, 16 and 17 to the "Consolidated Financial Statements"
for further information.

     Cash flows provided by operating activities increased by $9.7 million to
$30.2 million at December 31, 1999, and increased by $6.4 million to $20.5
million at December 31, 1998. The increase in cash flows provided in 1999 was
due to a decrease in assets held for sale. The change in 1998 was primarily
attributable to an increase in net income and an increase in accrued income
taxes payable. Cash flows used by investing activities increased by $43.0
million to $117.1 million during 1999 and decreased $54.6 million during 1998 to
$74.1 million. The change in 1999 was primarily attributable to a much higher
level of purchases of investments and mortgage-backed securities available for
sale and increased purchases of whole loans. The decrease in 1998 was due to a
large reduction in the purchases of whole loans. Cash flows provided by
financing activities increased by $6.7 million to $70.0 million during 1999 due
to a significant increase in total borrowed funds offset by a decline in
deposits. The decrease of $40.9 million in cash flows provided by financing
activities to $63.3 million at December 31, 1998, was mainly attributable to a
smaller increase in deposits.

CAPITAL RESOURCES

     At December 31, 1999, the Company reported total capital of $130.3 million,
or 8.7% of total assets as compared to $121.1 million, or 8.6% at December 31,
1998. The Company and the Bank continue to maintain capital ratios in excess of
all applicable regulatory minimums.

     The capital position of banks and bank holding companies are regulated by
various Federal and state agencies. The following table presents regulatory
capital ratios under current regulatory and risk-based capital requirements as
of December 31, 1999:

</TABLE>

     Under the FDIC's prompt corrective action regulations promulgated pursuant
to the FDIC Improvement Act of 1991, the Bank has sufficient capital to be
considered "well capitalized". Therefore, the Bank is entitled to pay the lowest
deposit premiums possible.

     In January, 1999, the Company adopted a Shareholder Rights Plan and in
1998, the Company's Board of Directors approved a stock repurchase program.

     See Item 1, "Business -- Supervision and Regulation" and Note 12 to the
"Consolidated Financial Statements" for further information.

IMPACT OF INFLATION

     The Consolidated Financial Statements and related consolidated financial
data presented herein have been prepared in accordance with generally accepted
accounting principles which require the measurement of financial position and
operating results in terms of historical dollars without considering the changes
in the relative purchasing power of money over time due to inflation. The
primary impact of inflation on operations of Andover is reflected in increased
operating costs. Unlike most industrial companies, virtually all the assets and
liabilities of a financial institution are monetary in nature. As a result,
interest rates have a more significant impact on a financial institution's
performance than the effects of general levels of inflation. Interest rates do
not necessarily move in the same direction or to the same extent as the price of
goods and services.

YEAR 2000 DISCLOSURE

     The Year 2000 computer software compliance issues affected Andover and many
other financial institutions and companies in the U.S. The primary concern was
that computer programs would not recognize the proper date which could then
generate erroneous data or cause systems to fail, thereby creating an adverse
impact on the Company's business and possibly its operating results.

     The Company started its Year 2000 initiative in early 1997. Prior to the
end of 1999, the Company completed its assessment, testing and remediating of
Year 2000 issues. The Company developed multiple contingency plans, tested its
various software information systems, hardware components and non-technology
systems and arranged for the required human and financial resources to complete
its necessary remediation efforts.

     Due to the extensive planning and testing over the past three years, the
Company did not experience any Year 2000 difficulties with regards to software,
hardware or non-technology systems.

     Included in other noninterest expenses during 1999 were charges incurred in
connection with the modification or replacement of software and hardware in
order for the Company's computer systems to properly recognize the Year 2000.
The level of data processing expenses and consulting services incurred in 1999
was approximately $70,000 and $45,000, respectively. Total expenses incurred and
hardware capitalized were approximately $415,000 for the year ended December 31,
1999 and $700,000 over the course of the project.

RECENT ACCOUNTING DEVELOPMENTS

     In June, 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133"), which establishes new
accounting and reporting standards for derivative instruments. SFAS 133 requires
that an entity recognize all derivatives as either assets or liabilities and
measure those instruments at fair value. This statement, as amended by SFAS 137,
is effective for financial statements issued for all fiscal quarters of fiscal
years beginning after June 15, 2000. Early application is encouraged but
restatement of prior periods is prohibited. SFAS 133 is not expected to have a
material impact on the consolidated financial statements of the Company.

                          INDEPENDENT AUDITORS' REPORT



The Board of Directors and Stockholders
Andover Bancorp, Inc.:

     We have audited the accompanying consolidated balance sheets of Andover
Bancorp, Inc. and subsidiaries as of December 31, 1999 and 1998, and the related
consolidated statements of operations, changes in stockholders' equity and cash
flows for each of the years in the three-year period ended December 31, 1999.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Andover
Bancorp, Inc. and subsidiaries as of December 31, 1999 and 1998 and the results
of their operations and their cash flows for each of the years in the three-year
period ended December 31, 1999, in conformity with generally accepted accounting
principles.

                     ANDOVER BANCORP, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1999, 1998 and 1997

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Andover Bancorp, Inc. (the "Company") is a Delaware corporation and the
holding company of Andover Bank. Andover Bank (the "Bank") is a state-chartered
savings bank with its headquarters located in Andover, Massachusetts. The
Company provides a variety of loan and deposit services to its customers through
13 locations. The Company is supervised by the Board of Governors of the Federal
Reserve System ("FRB") and it is also subject to the jurisdiction of the
Massachusetts Board of Bank Incorporation, while the Bank is subject to
regulation and supervision by the Federal Deposit Insurance Corporation ("FDIC")
and the Massachusetts Commissioner of Banks (the "Commissioner"). The Bank's
deposits are insured by the FDIC and the Depositors Insurance Fund, Inc.
("DIF").
     Andover Bank NH was a wholly-owned de novo guaranty savings bank chartered
in September, 1995 and headquartered in Salem, New Hampshire. The Company merged
Andover Bank NH with and into Andover Bank as of close of business on June 30,
1999.
     The accounting and reporting policies of Andover Bancorp, Inc. and
subsidiaries conform with generally accepted accounting principles and general
practices within the banking industry. In preparing the financial statements,
management is required to make estimates and assumptions that affect the
reported amounts of assets and liabilities as of the date of the balance sheet
and income and expenses for the period. Actual results could differ
significantly from those estimates. Material estimates that are particularly
susceptible to change relate to the allowance for loan loss and the valuation of
mortgage servicing assets. The following is a summary of the more significant
accounting policies.

  Principles of Consolidation
     The consolidated financial statements include the accounts of Andover
Bancorp, Inc. and its subsidiaries, including its principal subsidiary Andover
Bank. All intercompany accounts and transactions have been eliminated in
consolidation. Certain amounts in the prior years' financial statements have
been reclassified to conform with the current year's presentation for
comparative purposes. Such reclassifications had no effect on net income. In
addition, the Company is reporting its results as one operating segment.

  Mortgage Banking Activities
     Loans held for sale in the secondary market are stated at the lower of
aggregate amortized cost or market value. Market value is estimated based on
outstanding investor commitments or, in the absence of such commitments, current
investor yield requirements. Net unrealized losses, if any, are provided for in
a valuation allowance by charges to operations. When loans are sold, a gain or
loss is recognized to the extent that the sale proceeds exceed or are less than
the carrying amount of the loans. Gains and losses are determined using the
specific identification method.
     The Company recognizes a servicing asset based on an allocation of the
carrying amount of the assets sold between the underlying asset sold and the
servicing obligation or other retained interests using the relative fair value
of the assets sold to the interests retained. These capitalized mortgage loan
servicing rights are a significant component of the net gains from sales of
assets held for sale income category.
     Mortgage loan servicing rights purchased or originated are amortized
against mortgage banking income using a method which approximates the level
yield method in proportion to, and over the period of, estimated net servicing
income. Prepayment experience on each mortgage servicing asset is reviewed
periodically, and, when actual prepayments exceed estimated prepayments, the
balance of the mortgage servicing asset is adjusted by a charge to the valuation
allowance. On a regular basis, the mortgage servicing assets are assessed for
impairment based on the fair value of such rights. The fair value is estimated
using market prices when available or, alternatively, using a valuation model
that calculates the present value of future servicing asset cash flows using
discount rates and prepayment assumptions that management believes market
participants would use. Any impairment in the fair value of those mortgage
servicing assets is recognized by a charge to the valuation allowance. The risk
characteristics of the underlying loans used to measure impairment of originated
and purchased mortgage loan servicing rights include the loan type, interest
rate, loan origination date, term to maturity and geographic location.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1999, 1998 and 1997

  Investments
     Investments include short-term, available for sale, held to maturity and
trading. Debt securities are classified as held to maturity only when there is
positive intent and ability to hold them to maturity. Such securities are
recorded at amortized cost, adjusted for amortization of premiums and accretion
of discounts and adjusted as necessary for estimated prepayments. Trading
securities are debt or equity securities held principally for the purpose of
selling in the near term. Such securities are recorded at fair value, with
unrealized gains and losses recorded in earnings. Investments available for sale
are any debt or equity securities not classified as either held to maturity or
trading securities. Such investments are recorded at fair value with changes in
fair value recorded as a separate component of stockholders' equity, net of the
related income tax effect. Originated mortgage loans converted to
mortgage-backed securities to be sold are classified as trading. Gains and
losses on sales of investment and mortgage-backed securities are recognized
using the specific identification method. Premiums and discounts on investment
and mortgage-backed securities are amortized or accreted into income by use of
the level-yield method. The yields on mortgage-backed securities are affected by
prepayments and changes in interest rates. If a decline in fair value below the
amortized cost basis of an investment or mortgage-backed security is judged to
be other than temporary, the cost basis of the security is written down to fair
value. The amount of the writedown is included as a charge against gain on sale
of securities. Short-term investments with original maturities of 90 days or
less are carried at cost, which approximates market value.

  Loans
     Accrual of interest income on loans and amortization of net deferred loan
fees are discontinued when loan payments are 90 days or more past due or earlier
when concern exists as to the ultimate collection of principal or interest. When
loans are placed on nonaccrual status, the interest receivable on the loan is
reversed against interest income of the current period. Non-performing loans are
not returned to performing status until the obligation is brought current, the
loan becomes well-secured and in the process of collection and, in either case,
when concern no longer exists as to the ultimate collectibility of principal or
interest. Interest received on nonaccruing loans is either applied against
principal or reported as income according to management's judgment as to the
collectibility of principal.
     Loan origination fees and related direct incremental loan origination costs
are deferred and amortized over the life of the related loans as yield
adjustments using the level yield method. When loans are sold or paid off, the
unamortized fees and costs are recognized to income. Purchased loan discounts
and premiums are amortized or accreted into income over the weighted average
repricing term of the underlying loans.

Allowance for Loan Losses
     The Bank maintains an allowance for possible losses that are inherent in
its loan portfolio. The allowance is increased by provisions charged against
earnings or by recoveries of previously charged-off loans. The allowance is
decreased as loans are charged-off.
     The allowance is an amount that management believes will be adequate for
loan losses based on evaluations of collectibility and prior loss experience,
changes in the nature and volume of the loan portfolio, overall portfolio
quality, specific problem loans and current and anticipated economic conditions
that may affect the borrower's ability to pay. A substantial portion of the
Bank's loans are secured by real estate in Massachusetts and New Hampshire.
Accordingly, the ultimate collectibility of a substantial portion of the Bank's
loan portfolio is susceptible to changes in market conditions in these areas.
     Management believes the allowance for loan losses is adequate. While
management uses available information to recognize losses on loans, future
additions to the allowance may be necessary based on changes in economic
conditions. In addition, various regulatory agencies, as an integral part of
their examination process, periodically review the Bank's allowance for loan
losses. Such agencies may require the Bank to recognize additions to the
allowance based on their judgments about information available to them at the
time of their examination.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1999, 1998 and 1997

     Impaired loans are commercial, commercial real estate, and individually
significant mortgage and consumer loans for which it is probable that the
Company will not be able to collect all amounts due according to the contractual
terms of the loan agreement. The definition of "impaired loans" is not the same
as the definition of "nonaccrual loans", although the two categories overlap.
Nonaccrual loans include impaired loans and are those on which the accrual of
interest is discontinued when collectibility of principal or interest is
uncertain or payments of principal or interest have been contractually past due
90 days. The Company may choose to place a loan on nonaccrual status due to
payment delinquency, while not classifying the loan as impaired due to
insignificant payment delays and insignificant shortfalls in payment amounts.
Factors considered by management in determining impairment include payment
status and collateral value. The amount of impairment for these types of
impaired loans is determined by the difference between the present value of the
expected cash flows related to the loan, using the original contractual interest
rate and its recorded value, or, as a practical expedient in the case of
collateral dependent loans, the difference between the fair value of the
collateral and the recorded amount of the loans. When foreclosure is probable,
impairment is measured based on the fair value of the collateral. Loan
restructurings at below current market rates are reported as impaired loans and
impairment is measured as described above using the loan's pre-modification rate
of interest. Income received on impaired loans is recognized in income similar
to nonaccrual loans.

  Other Real Estate Owned
     Other real estate owned is comprised of properties acquired through
foreclosure proceedings, acceptance of a deed in lieu of foreclosure or when the
Bank is in possession of the collateral. Real estate owned is recorded at the
lower of the carrying value of the loan or the net fair value of the property.
Losses arising from the acquisition of such properties are charged against the
allowance for loan losses. Operating expenses, net of related income, and any
provisions to increase the valuation allowance are charged to real estate
operations. Subsequent declines in net fair value are charged-off to the
valuation allowance while gains and losses upon disposition are reflected in
real estate operations. Management believes the allowance is adequate to provide
for potential losses. However, future additions to the valuation allowance may
be necessary based on changes in economic conditions.

  Premises and Equipment
     Premises and equipment are stated at cost less accumulated depreciation.
Depreciation or amortization is computed on the straight-line method over the
lesser of the estimated useful lives of the assets or over the terms of their
respective leases for leasehold improvements. It is the Company's practice to
charge the cost of maintenance and repairs to operations when incurred; major
expenditures for improvements are capitalized and depreciated.

  Income Taxes
     Income taxes are accounted for using the asset and liability method of
accounting. Under the asset and liability method, deferred tax assets and
liabilities are recognized for the future tax consequences attributable to
differences between the financial statement carrying amounts of existing assets
and liabilities and their respective tax basis and operating loss and tax credit
carryforwards. Deferred tax assets and liabilities are measured using enacted
tax rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on
deferred tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date. The valuation allowance
related to deferred tax assets is recognized when, in management's judgment, it
is more likely than not that all, or a portion of, such deferred tax assets will
not be realized.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                        December 31, 1999, 1998 and 1997

  Employee Benefits
     The Company accounts for pension and postretirement benefits on the net
periodic cost method for financial reporting purposes. This method recognizes
the compensation cost of any employee's benefit over that employee's approximate
service period. After evaluating the Company's pension plan in early 1999, the
Company elected to terminate the plan. In its stead, the Bank increased the
employer contribution to the 401(k) plan and adopted a new replacement defined
contribution plan effective January 1, 2000. Due to the termination of the
pension plan, the Company recognized curtailment and settlement gains of $1.6
million in 1999.
     The Company continues to follow APB Opinion No. 25 "Accounting for Stock
Issued to Employees" as permitted by Statement of Financial Accounting Standards
No. 123 "Accounting for Stock-Based Compensation" ("SFAS 123"). For companies
that elect to continue using APB 25, SFAS 123 requires disclosure of the pro
forma effect of using the fair value method of accounting for stock-based
compensation that is encouraged by SFAS 123. The proforma disclosures include
the effects of all awards granted on or after January 1, 1995. See footnote 14
for the expanded disclosures required by SFAS 123.

  Earnings Per Share
     There are two methods of calculating earnings per share: basic and diluted.
Basic earnings per share excludes common stock equivalents and is computed by
dividing net income by the weighted average number of common shares outstanding
for the period. Diluted earnings per share gives effect to all potential
dilutive common shares using the average market price of the Company's common
stock for the period plus the weighted average number of common shares
outstanding for the equivalent period of time.

     A reconciliation of the common shares outstanding for the three years ended
December 31, follows:

     At December 31, 1999, 1998 and 1997, mortgage loans partially or wholly
owned by others and serviced by the Company amounted to approximately
$956,358,000, $894,432,000 and $971,041,000 respectively, and are not reflected
in the accompanying consolidated financial statements because they are not
assets of the Company. The custodial balances included in the demand deposits
totaled $12,689,000 in 1999, $22,627,000 in 1998 and $16,422,000 in 1997.

     During 1999, 1998 and 1997, the Company purchased mortgage servicing rights
to $233.2 million, $184.7 million and $228.8 million, respectively, in
residential first mortgage loans. These purchased balances are included in the
loans serviced for others reflected above. Gains resulting from the
capitalization of originated mortgage servicing rights are included in net gains
on assets held for sale. Amortization of the mortgage servicing assets and the
provisions for the valuation allowance are included as a reduction of mortgage
banking income. However, credits for the valuation allowance increase mortgage
banking income.

(9)  OTHER BORROWINGS

     Other borrowings consist of various short-term borrowings that typically
have a maturity date of 90 days or less. However, FHLB overnight and federal
funds purchased have maturities of one day. In addition, the Bank enters into
sales of securities under agreements to repurchase. These agreements are treated
as financings and the obligations to repurchase securities sold are reflected as
a liability in the consolidated balance sheets and the securities underlying the
agreements remain in the asset accounts. The securities underlying the
agreements are held by third parties as custodian for the Bank. The Bank has
also established overnight corporate customer repurchase agreements whereby
collateral is set aside by the Bank's custodian and the rates paid approximate
short term deposit or market interest rates (see note 3).

     The composition of other borrowings at December 31 follows:

     The existing net deductible temporary differences that give rise to the net
deferred income tax asset are expected to reverse in periods in which the
Company will generate net taxable income. At December 31, 1999, the net deferred
tax asset is supported by recoverable income taxes of approximately $23.0
million. It should be noted, however, that factors beyond management's control,
such as the general state of the economy and real estate values, can affect
levels of taxable income and that no assurance can be given that sufficient
taxable income will be generated to fully absorb gross deductible temporary
differences.

The components of the net deferred taxes receivable for the years ended December
31, follow:

(12) STOCKHOLDERS' EQUITY
     Preferred Stock
     In connection with the Company's adoption of a Shareholder Rights Plan on
January 21, 1999, the Company established a series of 100,000 shares of
preferred stock designated as Series A Junior Participating Cumulative Preferred
Stock, par value $0.10 per share ("Series A Stock") and declared a dividend of
one Preferred Stock Purchase Right (the "Right") for each outstanding share of
the Company's Common Stock held of record as of February 16, 1999.

                     ANDOVER BANCORP, INC. AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
                        December 31, 1999, 1998 and 1997

     Pursuant to the Shareholder Rights Plan, each Right entitles the holder to
purchase a unit consisting of one one-thousandth of a share of Series A Stock,
par value $0.10 per share, at an initial cash exercise price of $130.00 per
unit, subject to adjustment. The Rights are not exercisable and remain attached
to all outstanding shares of Common Stock until the earliest of (i) ten calendar
days following a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired beneficial ownership of
15% or more of the outstanding shares of Common Stock (the date of said
announcement being referred to as the "Stock Acquisition Date"), (ii) ten
business days following the commencement of a tender offer or exchange offer
that could result in a person or group becoming an Acquiring Person or (iii) the
declaration by the Board of Directors that a person is an "Adverse Person", as
such term is defined in the Shareholder Rights Plan.
     In the event that a Stock Acquisition Date occurs or the Board of Directors
determines that a person is an Adverse Person, each holder of a Right will be
entitled to receive upon exercise that number of units of Series A Stock having
a market value of two times the exercise price of the Right. In the event that,
at any time following the Stock Acquisition Date, (i) the Company is acquired in
a merger or other business combination transaction or (ii) 50% or more of the
Company's assets or earning power is sold, each holder of a Right shall
thereafter have the right to receive, upon exercise, common stock of the
acquiring company having a market value equal to two times the exercise price of
the Right. The Rights have no voting or dividend privileges and, until they
become exercisable, have no dilutive effect on the earnings of the Company. The
Rights expire on February 16, 2009.
     The holders of Series A Stock would be entitled to a preference with
respect to dividends and liquidation.

Stock Repurchase Plan
     In October 1998, the Company's Board of Directors approved a common stock
repurchase program authorizing the repurchase of 5%, or 324,000 shares, of the
Company's common stock outstanding. Purchases may be made on the open market or
in private transactions. As of December 31, 1999, no shares had been
repurchased.

Retained Earnings
     The Company may not declare or pay cash dividends on its common stock if
the effect thereof would cause its net worth to be reduced below regulatory net
worth requirements or if such declaration and payment would otherwise violate
regulatory requirements.
     The Bank is subject to various regulatory capital requirements administered
by federal banking agencies. Failure to meet minimum capital requirements can
initiate certain mandatory, and possibly additional discretionary, actions by
regulators that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities, and certain off-balance sheet items as calculated under regulatory
accounting practices. The Bank's capital amounts and classification are also
subject to qualitative judgments by the regulators about components, risk
weightings, and other factors.
     Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier 1 capital (as defined in the regulations) to risk
weighted assets (as defined), and of Tier 1 capital (as defined) to average
assets (as defined). Management believes that as of December 31, 1999, the Bank
met all capital adequacy requirements to which they are subject.
     As of December 31, 1999, the most recent notification from the FDIC
categorized the Bank as well capitalized under the prompt corrective action
provisions. To be categorized as well capitalized, the Bank must maintain total
capital risk-based, Tier 1 capital risk-based, and Tier 1 capital leverage
ratios as set forth in the table. There are no conditions or events since that
notification that management believes would cause a change in the Bank's
categorization.

(14) EMPLOYEE BENEFITS
     Pension Plan and Postretirement Benefits Other Than Pensions
     The Company sponsors a non-contributory defined benefit pension plan that
covers all employees who meet specified age and employment requirements. The
plan provides for benefits to be paid to eligible employees at retirement based
primarily upon their years of service with the Company and compensation levels
near retirement. In addition, the Bank provides health care and life insurance
benefits for certain eligible retired employees.

     The Company applies APB Opinion No. 25 in accounting for stock options and,
accordingly, no compensation expense has been recognized in the financial
statements. Had the Company determined compensation expense based on the fair
value at the grant date for its stock options under SFAS 123, the Company's net
income would have been reduced to the pro forma amounts indicated below:

     Employee Stock Ownership Plan
     The Company maintains an Employee Stock Ownership Plan (the "ESOP") that
covers all employees who meet specified age and length of service requirements.
Contributions are made for the purchase of additional shares of Company stock
and accordingly, a charge to salaries and employee benefits expense is recorded.
In 1999, 11,566 shares of common stock were purchased in the open market at an
average price of $30.63 per share, which when combined with forfeited shares are
allocated to participants proportionately to their gross wages. In 1998 and
1997, 11,552 and 15,316 shares were purchased at an average price of $32.32 and
$24.45 per share, respectively. Contributions by the Bank to the ESOP for
participants for the years ended December 31, 1999, October 31, 1998 and 1997
were $355,000, $375,000 and $385,000, respectively.

     Thrift Incentive Plan
     The Company has an employee tax deferred thrift incentive plan (the
"401(k)") under which individual employee contributions to the plan are matched
within certain limitations by the Bank. All employees who meet specified age and
length of service requirements are eligible to participate in the 401(k) plan.
The amounts matched by the Bank are included in salaries and employee benefits
expense. The amounts matched for the years ended December 31, 1999, 1998 and
1997 were $91,000, $94,000 and $71,000, respectively.

     Officers Incentive Compensation Plan
     The Incentive Compensation Plan provides for the payment of bonuses to
officers under certain circumstances based upon the Company's pre-tax earnings
adjusted for gains or losses from sales of assets, targeted returns on assets
and the individual's accomplishment of established goals and objectives. Amounts
are to be allocated to participants as determined by the Company's Compensation
and Option Committee based on the recommendation of the President and subject to
approval by its Board of Directors.
     In 1999, 1998 and 1997 $620,000, $490,000 and $318,000, respectively, was
charged to salaries and employee benefits expense under this plan.

Executive Officer Employment and Termination Agreements
     The Company maintains an employment agreement with its President and Chief
Executive Officer, The employment agreement generally provides for the continued
payment of specified compensation and benefits for specified periods after
termination, unless the termination is for "cause" as defined in the employment
agreement. In addition, the Company has entered into special termination
agreements with its President and Chief Executive Officer and certain other
executives which provide for the payment, under certain circumstances, of
lump-sum amounts upon termination following a "change of control" which is
generally defined to mean a person or group acquiring ownership of 25% or more
of the shares of the Company.

Deferred Compensation Plan
     The Company has adopted a deferred compensation plan for its directors
whereby a non-employee director can elect to defer earned fees to future years
with benefits commencing at retirement. In 1996, this unfunded plan was amended
to allow the directors to change their deferred compensation account to
equivalent stock units in the Company's common stock, permit distribution upon
retirement to be paid in shares of common stock, or to choose to receive
interest credits based on an equivalent rate on a term certificate of deposit.
The amended deferred compensation plan reserved 75,000 shares of common stock,
approximately 50,000 shares remain unallocated. The deferred compensation
attributed to the directors for the years ended December 31, 1999, 1998 and 1997
totaled $159,000, $108,000 and $89,000, respectively. In 1999, 5,553 equivalent
stock units were allocated at an average price of $30.81. In 1998 and 1997,
3,295 and 4,277 equivalent stock units were allocated at an average price of
$32.79 and $23.93 per stock unit, respectively.

(15) FAIR VALUES OF FINANCIAL INSTRUMENTS
     Fair value estimates are based on existing on- and off-balance sheet
financial instruments without attempting to estimate the value of anticipated
future business and the value of assets and liabilities that are not considered
financial instruments. Other significant assets and liabilities that are not
considered financial assets or liabilities include real estate acquired by
foreclosure, the deferred income tax asset, office properties and equipment,
core deposits and other intangibles. In addition, the tax ramifications related
to the realization of the unrealized gains and losses can have a significant
effect on fair value estimates and have not been considered in any of the
estimates. Accordingly, the aggregate fair value amounts presented do not
represent the underlying value of the Company. The estimated fair value amounts
have been determined by using available quoted market information or other
appropriate valuation methodologies.

     The fair value estimates provided are made at a specific point in time,
based on relevant market information and the characteristics of the financial
instrument. The estimates do not provide for any premiums or discounts that
could result from concentrations of ownership of a financial instrument. Because
no active market exists for a portion of the Company's financial instruments,
certain fair value estimates are based on subjective judgments regarding current
economic conditions, risk characteristics of the financial instruments, future
expected loss experience, prepayment assumptions, and other factors. The
resulting estimates involve uncertainties and therefore cannot be determined
with precision. Changes made to any of the underlying assumptions could
significantly affect the estimates.

valued at December 31 using quoted available market prices follow:

</TABLE>

     The following methods and assumptions were used to estimate fair value of
each class of financial instrument for which it is practicable to estimate fair
value. The fair values for investments available for sale and held to maturity
are based on quoted bid prices received from securities dealers or third party
pricing services. Commitments to originate loans and forward commitments to sell
loans have been considered in the value of assets held for sale. Loans are
estimated by discounting contractual cash flows adjusted for prepayment
estimates and using discount rates approximately equal to current market rates
on loans with similar characteristics and maturities. The incremental credit
risk for non-performing loans has been considered in the determination of the
fair value of loans. Excess servicing is based on the present value of the
estimated cash flows using a current risk rate and taking into consideration
estimated prepayments. Fixed rate certificates and Federal Home Loan Bank
advances are based on the discounted value of contractual cash flows. The
discount rates used are representative of approximate rates currently offered on
instruments with similar remaining maturities. The fair values for cash and
short-term investments approximate their carrying amounts because of the short
maturity of these instruments. The fair values of accrued interest receivable,
variable rate certificates, securities sold under agreements to repurchase and
mortgagors' escrow accounts approximate their carrying amounts because of the
short-term nature of these financial instruments. The fair value of stock in the
Federal Home Loan Bank of Boston equals its carrying amount as reported in the
balance sheet because this stock is redeemable only at full par by the FHLB. The
fair values of demand deposit accounts, NOW accounts, regular savings accounts
and money market accounts are equal to their respective carrying amounts since
they are equal to the amounts payable on demand at the reporting date. The
majority of the Company's commitments for unused lines and outstanding standby
letters of credit and unadvanced portions of loans are at floating rates and,
therefore, there is no fair value adjustment.

(17) FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK, COMMITMENTS AND
     CONTINGENCIES
     The Company is party to financial instruments with off-balance sheet risk
in the normal course of business to meet the financing needs of its customers
and to reduce its own exposure to fluctuations in interest rates. These
financial instruments include commitments to originate loans, standby letters of
credit, recourse arrangements on assets sold, and forward commitments to sell
loans. The instruments involve, to varying degrees, elements of credit and
interest rate risk in excess of the amounts recognized in the Consolidated
Balance Sheets. The contract or notional amounts of those instruments reflect
the extent of involvement the Company has in particular classes of financial
instruments.
     The Company's exposure to credit loss in the event of nonperformance by the
other party to the financial instrument for loan commitments, standby letters of
credit and recourse arrangements is represented by the contractual amount of
those instruments. The Company uses the same credit policies in making
commitments and conditional obligations as it does for on-balance sheet
instruments. For forward commitments to sell loans and mortgage-backed
securities, the contract or notional amounts do not represent exposure to credit
loss. The Company monitors the credit risk of its forward commitments through
credit approvals, limits, and monitoring procedures.

</TABLE>

     Commitments to originate loans, unused lines of credit, and unadvanced
portions of loans are agreements to lend to a customer provided there is no
violation of any condition established in the contract. Commitments generally
have fixed expiration dates or other termination clauses and may require payment
of a fee. Since a portion of the commitments are expected to expire without
being drawn upon, the total commitment amounts do not necessarily represent
future cash requirements. The Company evaluates each customer's creditworthiness
on a case-by-case basis. The amount of collateral obtained, if deemed necessary
by the Company upon extension of credit, is based on management's credit
evaluation of the borrower. Collateral held varies but may include accounts
receivable, inventory, equipment and real estate. Standby letters of credit are
conditional commitments issued by the Company to guarantee the performance by a
customer to a third party. The credit risk in issuing letters of credit is
essentially the same as that involved in extending loan facilities to customers.
     The Company has retained credit risk on certain residential mortgage loans
sold with recourse prior to June, 1990. Accordingly, the Company has retained
the risk of loss resulting from any foreclosures on such loans.
     Forward commitments to sell loans or mortgage-backed securities are
contracts which the Company enters into for the purpose of reducing the interest
rate risk associated with originating loans for sale. In order to fulfill a
forward commitment, the Company typically exchanges its current production of
loans for mortgage-backed securities through FNMA or FHLMC which are then
delivered to a national securities firm at a future date at prices or yields
specified by the contracts. Risks may arise from the possible inability of the
Company to originate loans to fulfill these contracts, in which case the Company
would normally purchase securities in the open market to deliver against the
contract. Unrealized gains and losses on contracts used for the Company's closed
loans and pipeline of loans expected to close are considered in adjusting
carrying values of the loans held for sale to the lower of cost or market.
     As a nonmember of the Federal Reserve System, the Company is required to
maintain certain reserve requirements or vault cash and/or deposits with the
Federal Reserve Bank of Boston. The amount of this reserve requirement, included
in "Cash and due from banks", was $992,000 and $1,141,000 at December 31, 1999
and 1998, respectively.
     A number of legal claims against the Company arising in the normal course
of business were outstanding at December 31, 1999. Management, after reviewing
these claims with legal counsel, is of the opinion that the resolution of these
claims will not have a material effect on the Company's financial position.

(18) SUBSEQUENT EVENT (UNAUDITED)

     On January 26, 2000, the Company entered into a definitive agreement to
acquire GBT Bancorp ("GBT") and its wholly-owned subsidiary, Gloucester Bank and
Trust Company, a Massachusetts-chartered trust company with two banking offices
in Gloucester, Massachusetts. This agreement is subject to a number of
conditions, including regulatory approval. Under the terms of the agreement,
Gloucester Bank and Trust Company will continue to operate under its own name as
a subsidiary of Andover Bancorp, Inc.
     At December 31, 1999, GBT had $130.9 million in assets, primarily
commercial real estate loans and investment securities, and deposits of $103.5
million. The acquisition will be accounted for as a purchase and had a total
value of approximately $16.2 million on the date announced. The estimated
portion of goodwill attributed to this transaction is approximately $9.2
million.

     The following presentation reflects the key line items on a historical
basis, as reported, for GBT and Andover, and on a proforma combined basis
assuming the merger was in effect for the year ended December 31, 1999:

(19) QUARTERLY RESULTS OF OPERATIONS (UNAUDITED)
     Quarterly earnings per share is calculated by dividing quarterly net income
by the average shares outstanding each quarter. Therefore, the sum of the
quarters may not equal the net earnings per common share for the year. A
discussion of the difference between basic and diluted earnings per share is
presented in footnote 1.
     Summaries of consolidated operating results on a quarterly basis for the
years ended December 31, follow:
