Bancorp,  Inc.  (the  "company")  wishes to caution  readers that the  following
important  factors,  among  others,  may have  affected  and could in the future
affect  the  company's  results  and  could  cause  the  company's  results  for

forward-looking  statement  made  herein:  (i) the effect of changes in laws and

                          Notes to Financial Statements

(1)      Organization of Holding Company

Enterprise Bancorp, Inc. (the "company") is a Massachusetts  corporation,  which
was  organized on February 29, 1996,  at the  direction of  Enterprise  Bank and
Trust Company,  a Massachusetts  trust company (the "bank"),  for the purpose of
becoming the holding company for the bank. The company had no material assets or
operations prior to completion of the holding company reorganization on July 26,
1996.

(2)      Basis of Presentation

The accompanying  unaudited  financial  statements should be read in conjunction
with the company's  December 31, 1998,  audited  financial  statements and notes
thereto.  Interim  results  are not  necessarily  indicative  of  results  to be
expected for the entire year.

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 revenues and expenses for the period.  Actual
results  could  differ  from  those  estimates.   Material  estimates  that  are
particularly  susceptible to change relate to the determination of the allowance
for loan losses.

In the opinion of management,  the accompanying financial statements reflect all
necessary  adjustments  consisting  of  normal  recurring  accruals  for a  fair
presentation.

(3)      Earnings per share

Basic  earnings per share are  calculated  by dividing net income by the year to
date  weighted  average  number of common  shares  outstanding  for the  period.
Diluted  earnings  per share  reflect  the  effect on  weighted  average  shares
outstanding  of the number of additional  shares  outstanding  if dilutive stock
options were converted into common stock using the treasury stock method.

(4)      Dividend Reinvestment Plan

The Board of Directors adopted a Dividend Reinvestment Plan (the "DRP"). The DRP
enables stockholders,  at their discretion,  to elect to reinvest dividends paid
on their  outstanding  shares of company  common stock by purchasing  additional
shares of company common stock from the company.  The stockholders  utilized the
DRP to reinvest  $388,000 of the dividends paid by the company in 1999 in 27,054
shares of the company's common stock.

(5)      Purchase and Assumption Agreement

On  September  22,  1999,  the company and the bank  entered into a Purchase and
Assumption  Agreement (the "Agreement") with Fleet Financial Group, Inc. and its
principal banking  subsidiary,  Fleet National Bank,  pursuant to which the bank
will purchase two branch offices of Fleet National Bank. The bank's  acquisition
of these  branch  offices is part of the overall  sale of 306 branch  offices of
Fleet National Bank and  BankBoston,  N.A. to be completed in accordance  with a
divestiture  order  of  the  United  States  Department  of  Justice  issued  in
connection with the merger of BankBoston Corporation with Fleet Financial Group,
Inc.  The bank's  acquisition  of the branches  remains  subject to the parties'
receipt of required federal and state  regulatory  approvals and satisfaction of
various other  customary  closing  conditions  specified in the  Agreement.  The
parties presently anticipate that the bank's acquisition of the branches will be
completed in the second or third quarter of 2000.

(6)      Reclassification

Certain fiscal 1998  information  has been  reclassified  to conform to the 1999
presentation.

On April 20, 1999,  the Board of Directors  declared a dividend in the amount of
$0.21 per share to be paid on or about July 1, 1999 to shareholders of record as
of the close of business on June 11,  1999.  The Board of  Directors  intends to
consider  the  payment  of future  dividends  on an annual  basis.  The Board of
Directors  adopted a Dividend  Reinvestment  Plan (the  "DRP").  The DRP enables
stockholders,  in their discretion, to elect to reinvest dividends paid on their
outstanding  shares of company common stock by purchasing  additional  shares of
company  common stock from the  company.  The  stockholders  utilized the DRP to
reinvest  $388,000 of the dividends paid by the company in 1999 in 27,054 shares
of the company's common stock.

On  September  22,  1999,  the company and the bank  entered into a Purchase and
Assumption  Agreement (the "Agreement") with Fleet Financial Group, Inc. and its
principal banking  subsidiary,  Fleet National Bank,  pursuant to which the bank
will purchase two branch  offices of Fleet National Bank. The bank will purchase
approximately $7.1 million in loans,  furniture,  fixtures, and equipment with a
net book value of  approximately  $0.1  million,  and will purchase the land and
buildings at agreed upon values totaling  approximately  $1.5 million.  The bank
will  assume  $66.5   million  in  deposits,   in  exchange  for  a  premium  of
approximately  13.6% of total deposits,  presently estimated to be $9.1 million.
The  acquisition  will close with a net cash payment from Fleet National Bank to
the bank. Management  anticipates using the proceeds to repay the bank's current
Federal  Home Loan  Bank  ("FHLB")  borrowings  and/or to  increase  the  bank's
investment portfolio.

The bank's  acquisition  of these branch  offices is part of the overall sale of
306 branch offices of Fleet National Bank and  BankBoston,  N.A. to be completed
in  accordance  with a  divestiture  order of the United  States  Department  of
Justice  issued in  connection  with the merger of BankBoston  Corporation  with
Fleet  Financial  Group,  Inc. The bank's  acquisition  of the branches  remains
subject  to the  parties'  receipt  of  required  federal  and state  regulatory
approvals  and  satisfaction  of  various  other  customary  closing  conditions
specified in the Agreement.  The parties  presently  anticipate  that the bank's
acquisition  of the branches will be completed in the second or third quarter of
2000.  However,  no  assurance  can  be  given  that  the  acquisition  will  be
consummated.

                                       8


The company  presently  intends to raise  approximately  $14.5  million  from an
offering of trust preferred  securities to be made in the fourth quarter of 1999
or the first  quarter  of 2000.  However,  no  assurance  can be given  that the
offering  will be  consummated.  The company  currently  intends to contribute a
portion  of  the  offering  proceeds  to  the  bank.  This  anticipated  capital
contribution is intended to ensure that the bank remains "well  capitalized" for
regulatory purposes following the completion of the acquisition.  The completion
of the trust  preferred  offering is not a condition  to the parties  respective
obligations under the Agreement and management does not believe that the company
would be required to raise additional  capital in order to obtain the regulatory
approvals required for the transactions contemplated by the Agreement.

Balance Sheet
Total Assets

Total assets  increased  $53.5 million,  or 14.9%,  since December 31, 1998. The
increase  is  primarily  attributable  to an  increase  in gross  loans of $27.9
million, and in increase in investments of $25.4 million. The increase in assets
was funded by an  increase  in  short-term  borrowings  of $38.1  million and an
increase in deposits of $15.6 million.

Investments

At  September  30,  1999,  all  of  the  company's  investment  securities  were
classified as  available-for-sale  and carried at fair value. The net unrealized
loss at September 30, 1999 was $2.6 million,  compared to an unrealized  gain at
December 31, 1998 of $1.6 million.  The net  unrealized  gain (loss),  after tax
effects,  is shown  under  accumulated  other  comprehensive  income  (loss),  a
separate component of stockholders' equity, in the amounts of $(1.6) million and
$996 thousand at September 30, 1999 and December 31, 1998, respectively. The tax
effects are recorded as a change to deferred income taxes,  as discussed  below.
The change in the net  unrealized  gain  (loss) was due to an increase in market
interest rates since the end of 1998.

Loans

Total loans, before the allowance for loan losses, were $243.1 million, or 58.7%
of total assets, at September 30, 1999,  compared to $215.2 million, or 59.7% of
total assets,  at December 31, 1998.  The increase in loans of $27.9 million was
primarily attributed to continued strong loan origination in the commercial real
estate and  commercial  loan  portfolios.  The bank  continues to pursue  active
customer  calling  efforts as well as increased  marketing  and  advertising  to
identify quality-lending opportunities.

Premises and Equipment

Premises and  equipment  increased  by $1.8  million  from  December 31, 1998 to
September 30, 1999. The increase was primarily attributed to the construction of
the new Westford  branch,  scheduled  for opening in November of 1999,  and from
various  leasehold  improvements for  administrative  and executive office space
necessary due to the bank's growth.

Deferred Income Taxes

The  increase in deferred  income  taxes was caused  primarily  by a decrease in
investment  market values from an  unrealized  gain at December 31, 1998 of $1.6
million to an  unrealized  loss of $2.6  million at  September  30,  1999.  This
resulted in the deferred tax asset  increasing from a $0.6 million  deferred tax
liability  as of  December  31,  1998 to a $1.0  million  deferred  tax asset at
September 30, 1999. Deposits and Borrowings

Total deposits, including escrow deposits of borrowers, increased $15.6 million,
or 4.9%,  during the first nine months of 1999 from  $318.4  million at December
31, 1998, to $334.0  million at September  30, 1999.  The increase was primarily
due to increased market  penetration of the bank's newer branches and aggressive
customer calling efforts.

Total  borrowings,  consisting of securities sold under agreements to repurchase
and FHLB  (Federal  Home Loan Bank)  borrowings,  increased  $38.1  million,  or
315.3%,  from $12.1  million at December 31, 1998 to $50.2  million at September
30, 1999. Management periodically takes advantage of opportunities to fund asset
growth with borrowings, but on a long-term basis the bank intends to replace any
FHLB borrowings with deposits.  Management also actively uses FHLB borrowings in
managing  the  bank's  asset/liability  position.  The bank had FHLB  borrowings
outstanding  of $25.5  million at September 30, 1999 compared to $0.5 million at
December  31,  1998.  The  bank  had the  ability  to  borrow  approximately  an
additional $58.1 million at September 30, 1999.

Total  non-performing  loans  decreased  $0.3  million from  September  30, 1998
through  September 30, 1999.  The ratio of  non-performing  loans to gross loans
decreased  from 0.55% to 0.35%  during this  period.  The primary  cause for the
declines  was  the  removal  of  several  commercial  and  consumer  loans  from
non-accrual status.  These loans were either paid in full or brought current and
assessed as fully collectable by management.

                                       11


Total  non-performing  loans  decreased  $0.5 million from  December 31, 1998 to
September 30, 1999. The ratio of  non-performing  loans to gross loans decreased
from 0.63% as of December  31, 1998 to 0.35%  during  this  period.  The primary
cause for the  decline  was the  pay-off of several  commercial  loans that were
classified  as  non-accrual.  The level of  non-performing  assets is  largely a
function of economic conditions and the overall banking environment,  as well as
the strength of the bank's loan underwriting. Adverse changes in local, regional
or  national   economic   conditions  could  negatively   impact  the  level  of
non-performing assets in the future, despite prudent underwriting.

Year 2000 Compliance

The statements in the following section include "Year 2000 Readiness Disclosure"
within the meaning of the Year 2000  Information  and Readiness  Disclosure Act.
This section contains certain  forward-looking  statements within the meaning of
Section 27A of the Securities Act of 1993, as amended.  The company's  readiness
for the Year 2000, and the eventual  effects of the Year 2000 on the company may
be materially different than projected.

The company has  determined,  tested and  remediated the impact of the so-called
"millennium" or "Y2K" bug (i.e.,  that many existing computer chips and programs
use only two digits to  identify  the year in a date field and if such  programs
are  not  corrected  many  computer  applications  or  computer  chip  dependent
operations  could fail or create  erroneous  results by or beginning in the year
2000).  Every department and function of the company is affected and is included
in the  company's  analysis and  compliance  process.  The  remediation  efforts
discussed below relate to both  information  technology  systems (i.e.  computer
systems, phone systems, telecommunications, etc.) and non-information technology
systems (i.e. alarm systems,  security systems,  elevators,  electrical systems,
etc.).

The company primarily  utilized internal resources to manage the Y2K remediation
process and test, update,  and/or replace all software  information  systems for
Y2K modifications.  The company has a "Year 2000 Steering Committee"  consisting
of various members of senior  management and all department  managers.  The Year
2000 Steering Committee's purpose is to evaluate risks, formulate timetables and
allocate  resources to ensure  timely and  effective  completion of Y2K testing,
remediation  and  contingency  planning.  The  company  also  has  a  technology
committee,  consisting  of  certain  members  of  the  Board  of  Directors  and
management,  which oversees the Year 2000 Steering  Committee and is responsible
for ensuring  proper  reporting of results to the full Board of  Directors.  One
full time information  system specialist and one consultant on a part time basis
are  solely  devoted  to Y2K  issues.  Many other  employees  are also  actively
involved  including  each  department  manager and members of their  staff.  The
company also  utilizes  external  resources  (information  systems  consultants,
auditors,  speakers,  accountants,  etc.) as  deemed  necessary  by the  various
committees and management.

The company is addressing the Y2K issue in accordance with regulatory guidelines
promulgated by the Federal Financial Institutions Examination Council ("FFIEC").
The company  does not perform any  in-house  programming  and,  according to our
vendor,  since 1987, the system we use for our core loan and deposit  processing
was designed to process dated data into the next century and beyond.  Management
has  completed  testing  of  internal  mission  critical   information  systems.
Management has also completed the testing  required for mission critical systems
associated with service providers including the trust accounting system. Mission
critical  systems are those  critical to daily  operations  and failure of which
would  result in  definite  disruption  to  business.  Testing of the  company's
non-mission  critical  applications  will  continue  through  1999  and  will be
completed prior to any anticipated impact on its operating systems.  Contingency
plans have been  developed  for each  function so that the company is adequately
prepared  in the  event of a system  failure,  despite  remediation  efforts.  A
sub-committee  of the Y2K  Steering  Committee  has been  formed  to  facilitate
preparation  of contingency  plans.  These  contingency  plans will be reviewed,
enhanced  and  updated,  as  needed,  throughout  the  remainder  of  the  year.
Additionally,  the  bank has  formed  a  coalition  with  surrounding  financial
institutions  to  periodically  meet  and  discuss  contingency  plans  and pool
resources to deal with potential disruptions (i.e., failure of security systems,
failure of electrical grids, cash needs, etc.).

                                       12


Included in other non-interest  expenses are charges incurred in connection with
the preparation,  testing,  modification or replacement of software and hardware
in connection with the process of rendering the company's  computer  systems Y2K
compliant. Excluding internal salary and benefit costs, approximately $10,000 in
costs  associated with Y2K  remediation  efforts were expended in the year ended
December 31, 1998 and  $111,000  through the third  quarter of 1999.  Management
expects  that the costs  incurred to replace or upgrade  existing  hardware  and
software will be  capitalized  and  amortized in  accordance  with the company's
existing   accounting   policies,   while  miscellaneous   consulting,   salary,
maintenance  and  modification  costs will be expensed as incurred.  Anticipated
future costs,  excluding internal salary and benefit costs,  associated with Y2K
compliance are estimated at $75,000,  which mostly consists of consulting costs.
Due to short-term  personnel  constraints it was necessary to engage consultants
to assist in the Year 2000  management  process.  Other  than the one  dedicated
information  system specialist the company does not separately track the portion
of its  salary  and  benefit  costs  allocable  to the  Y2K  project.  It is not
anticipated  that  material  incremental  costs will be  incurred  in any single
period.

The cost of the project and the date on which the company  plans to complete the
Y2K modifications  are based on management's best estimates,  which were derived
utilizing  numerous   assumptions  of  future  events  including  the  continued
availability of certain  resources,  third party availability and other factors.
However,  there can be no guarantee  that these  estimates  will be achieved and
actual results could differ  materially from those plans.  Specific factors that
might  cause such  material  differences  include,  but are not  limited to, the
availability  and cost of  personnel  trained in this area,  employee  turnover,
non-compliance  of the  company's  vendors  or  service  providers  and  similar
uncertainties.  The  company  is working  closely  with all of its  vendors  and
service  providers to determine the extent to which the company is vulnerable to
those third parties' failure to remediate their own Y2K issues.

Management  recognizes  the potential risk of Y2K on the bank's  customers.  The
bank has approached  the credit risk  component of Y2K through  education of all
lending officers, education of customers, analysis of the bank's loan portfolio,
and consideration of Y2K in the underwriting of loans. All lending officers were
required to undergo  internal  training to learn the potential risks of Y2K. The
bank  has  sponsored  numerous  seminars  for bank  customers,  in  addition  to
distribution of literature regarding Y2K to all customers.  In 1998, an analysis
of the bank's  commercial  loan  portfolio was performed to determine  potential
exposure to Y2K risks.  Increases in the allowance for loan losses,  solely as a
result of Y2K, were not deemed  necessary.  Any new commercial  loans require an
assessment of the customer's Y2K compliance as part of preliminary underwriting.
The need for  additional  provisions  to the bank's  allowance  for loan  losses
resulting  from  borrowers' Y2K  compliance  problems will be considered,  on an
ongoing basis, based on management's assessment of the potential exposure of its
customer base to such problems.

In  addition,  Enterprise  Bank's  Trust  Division is working  with its business
partners to make sure that analysts are routinely monitoring  quarterly,  annual
and other  financial  reports on the companies  they invest in and that they are
monitoring reports for the required SEC disclosure.  For international companies
where there is no SEC mandate,  we are making inquiries of our business partners
to verify that analysts are looking for satisfactory disclosure of Y2K readiness
and if none is present that they are contacting management directly to determine
Y2K status.

The internal and external risks associated with Y2K are numerous. The company is
addressing the Y2K issue in accordance with regulatory guidelines promulgated by
the FFIEC.  However,  there can be no guarantee that the systems of the company,
bank customers or other associated  companies (i.e. electric company,  telephone
company,  printing  companies,  office  supply  companies,  etc.) will be timely
remediated. There can be no guarantee that the systems of third party vendors on
which the company's systems rely will be timely  remediated.  The failure of the
company or a critical  third  party  vendor to timely  remediate  Y2K issues may
cause systems malfunctions,  incorrect or incomplete transaction processing, the
inability  to  reconcile  accounting  books and  records,  or other  problematic
situations.

The company's operations and/or financial condition could possibly be negatively
impacted to the extent the company,  customers or entities  doing  business with
the company are unsuccessful in timely and properly  addressing their respective
Y2K compliance responsibilities.

Net Interest Income

The  company's  net interest  income was  $12,603,000  for the nine months ended
September 30, 1999, an increase of $1,002,000 or 8.6% from  $11,601,000  for the
nine months ended  September 30, 1998.  Interest  income  increased  $1,563,000,
primarily a result of an increase of average loan  balances of $30.6 million and
average  investment  balances of $17.6 million.  The increase in interest income
was partially offset by an increase in interest  expense of $561,000,  primarily
due to an increase in average deposits and short-term borrowings.

The average  tax-equivalent  yield on earning  assets in the nine  months  ended
September  30,  1999,  was 8.08%,  down 24 basis  points from 8.32% for the nine
months ended September 30, 1998. The decrease in average yield on earning assets
is primarily  attributable to a decrease in yield on loans,  partially offset by
an increase in yield on investment securities. The decrease in yield on loans is
primarily  attributable  to a 75 basis point  decrease in the prime lending rate
during the fourth quarter of 1998,  slightly offset by a 50 basis point increase
during the third quarter of 1999.  The increase in the tax  equivalent  yield on
investment  securities from 6.51% to 6.58% was primarily a result of a change in
investment mix to higher yielding  securities,  such as collateralized  mortgage
obligations  and  tax-exempt  municipal  securities.  The  average  rate paid on
interest  bearing  deposits and  short-term  borrowings in the nine months ended
September 30, 1999,  was 3.81%,  a decrease of 10 basis points from 3.91% in the
nine months ended  September 30, 1998,  primarily due to a drop in rates paid on
certificates  of deposit.  The average rate on short-term  borrowings  increased
from  3.67% to 4.58% as a result  of an  increase  in sweep  account  rates  and
increased borrowings from the FHLB.

The following table sets forth,  among other things, the extent to which changes
in interest rates and changes in the average balances of interest-earning assets
and  interest-bearing  liabilities  have  affected  interest  income and expense
during the nine months ended  September 30, 1999, and 1998. For each category of
interest-earning  assets  and  interest-bearing   liabilities,   information  is
provided  on changes  attributable  to: (1)  volume  (change in average  balance
multiplied  by prior year average  rate);  (2) interest  rate (change in average
interest rate multiplied by prior year average balance); and (3) rate and volume
(the remaining difference).

The bank manages its earning assets by fully using available  capital  resources
within what  management  believes are prudent  credit and  leverage  parameters.
Loans, investment securities, and federal funds sold comprise the bank's earning
assets.

                                                                 15


The  provision  for loan  losses  amounted  to  $270,000  and  $710,000  for the
nine-month  periods  ended  September  30, 1999 and 1998,  respectively.  Loans,
before the allowance for loan losses,  have  increased from $207.5  million,  at
September 30, 1998, to $243.1 million,  at September 30, 1999, or an increase of
17.2%. Despite the increase in the bank's loan portfolio,  there has not been an
increase  in  problem  assets  or a  significant  change  in  the  bank's  basic
underwriting  practices.  Management regularly reviews the levels of non-accrual
loans,  levels of charge-offs and recoveries,  levels of outstanding  loans, and
known and inherent risks in the loan portfolio. Based on this review, and taking
into account loan quality, and a net recovery position for the nine months ended
September  30,  1999,  management  determined  that  further  additions  to  the
allowance for loan losses were not necessary during the third quarter.

Non-Interest Income

Non-interest  income,  exclusive  of security  gains,  increased  by $208,000 to
$1,932,000 for the nine months ended September 30, 1999,  compared to $1,724,000
for the nine months ended September 30, 1998. This increase was caused primarily
by an increase in trust fees of $180,000.

Trust fees increased by $180,000,  or 25.6%, for the nine months ended September
30, 1999 compared to the same period in 1998 due to an increase in trust assets.

Deposit fees decreased by $26,000,  or 3.9%, for the nine months ended September
30, 1999, compared to the nine months ended September 30, 1998, due primarily to
a reduction in overdraft charges.

Gains on sales  of loans  increased  from  $132,000  for the nine  months  ended
September 30, 1998, to $148,000 for the nine months ended September 30, 1999, as
a result of increased  loan volume caused by low interest rates in the first six
months of the year and a strong real estate market.

Other income for the nine months ended  September  30, 1999,  was  $253,000,  an
increase of 10.5%,  from $229,000 for the nine months ended  September 30, 1998,
primarily due to increases in ATM fees,  safe deposit fees,  wire fees and debit
card fees.

Net gains on sales of investment  securities  decreased by $250,000 for the nine
months  ended  September  30,  1999,  from  $433,000  for the nine months  ended
September 30, 1998. The decrease was due to relatively  higher interest rates in
1999, resulting in less opportunity to restructure the investment portfolio.

Non-Interest Expense

Salaries  and  benefits  expense  totaled  $6,052,000  for the nine months ended
September 30, 1999, compared with $5,262,000 for the nine months ended September
30, 1998,  an increase of $790,000 or 15.0%.  This  increase was  primarily  the
result of new  hires,  to support  the  overall  growth of the bank,  and annual
salary increases.

Occupancy  expense was $1,809,000 for the nine months ended  September 30, 1999,
compared  with  $1,629,000  for the nine months ended  September  30,  1998,  an
increase of $180,000 or 11.0%.  The increase was  primarily  due to the addition
and renovation of new  facilities  for the bank's  accounting and loan servicing
departments,  executive offices,  commercial  lending offices,  customer service
center and the Westford branch.

Advertising and public relations  expenses  increased by $46,000,  or 12.8%, for
the nine months ended  September  30, 1999  compared to the same period in 1998.
The increase was primarily attributed to increased  advertising  associated with
the bank's growth.

Office and data processing  supplies expense decreased by $35,000, or 13.0%, for
the nine months  ended  September  30,  1999  compared to the same period in the
prior year. The decrease was primarily due to various cost savings programs.

Audit,  legal and other professional  expenses decreased by $104,000,  or 16.9%,
for the nine months ended  September 30, 1999 compared to the prior year period,
primarily as a result of professional  services incurred in 1998 relating to tax
saving strategies.

                                       16



Trust,  professional and custodial expenses increased by $25,000,  or 11.1%, for
the nine months ended September 30, 1999 as compared to the same period in 1998.
The increase was due to an increase in trust assets under  management as well as
additional services provided by the trust department.

The company's  effective tax rate for the nine months ending  September 30, 1999
was 27.3%  compared to 31.4% for the nine months ended  September 30, 1998.  The
reduction in rate was a result of the  implementation  of certain tax strategies
in 1998. Expenses for these strategies were fully absorbed in 1998.

Net Interest Income

The  company's  net interest  income was  $4,507,000  for the three months ended
September  30, 1999,  an increase of $417,000 or 10.2% from  $4,090,000  for the
three months ended  September  30, 1998.  Interest  income  increased  $728,000,
primarily a result of an increase of $31.8  million in the average  loan balance
and $39.7 million in the average  investment  balance.  The increase in interest
income was  partially  offset by an increase in  interest  expense of  $311,000,
primarily due to an increase in average time deposits and short-term borrowings.

The average  tax-equivalent  yield on earning  assets in the three  months ended
September  30,  1999,  was 8.11%,  down 23 basis  points from 8.34% in the three
months ended September 30, 1998. The decrease in average yield on earning assets
is  primarily  attributable  to a decrease in yield on loans,  and a decrease in
yield on  investment  securities.  The  decrease in yield on loans is  primarily
attributable  to a 75 basis point  decrease in the prime lending rate during the
fourth quarter of 1998,  slightly offset by a 50 basis point increase during the
third quarter of 1999.  The decrease in the tax  equivalent  yield on investment
securities from 6.65% to 6.40% was primarily a result of a decline in investment
rates  during the fourth  quarter  of 1998 and the  re-investment  of funds from
sales and calls of investment  securities  during that period.  The average rate
paid on interest bearing deposits and short-term  borrowings in the three months
ended  September 30, 1999, was 3.82%, a decrease of 6 basis points from 3.88% in
the three months ended September 30, 1998, primarily due to a drop in rates paid
on certificates of deposit. The average rate on short-term  borrowings increased
from  3.03% to  4.84% as a result  of an  increase  in  interest  rates on sweep
accounts and increased borrowings from FHLB.

The following table sets forth,  among other things, the extent to which changes
in interest rates and changes in the average balances of interest-earning assets
and  interest-bearing  liabilities  have  affected  interest  income and expense
during the three months ended September 30, 1999, and 1998. For each category of
interest-earning  assets  and  interest-bearing   liabilities,   information  is
provided  on changes  attributable  to: (1)  volume  (change in average  balance
multiplied  by prior year average  rate);  (2) interest  rate (change in average
interest rate multiplied by prior year average balance); and (3) rate and volume
(the remaining difference).

The  provision for loan losses  amounted to $0 and $440,000 for the  three-month
periods  ended  September  30, 1999 and 1998,  respectively.  Loans,  before the
allowance for loan losses,  have increased from $207.5 million, at September 30,
1998, to $243.1 million, at September 30, 1999, or an increase of 17.2%. Despite
the growth in the  bank's  loan  portfolio,  there has not been an  increase  in
problem assets or significant change in the bank's basic underwriting practices,
and the company has recorded a net recovery to the allowance for loan losses for
the nine month period ended September 30, 1999. Management regularly reviews the
level of non-accrual  loans,  levels of charge-offs  and  recoveries,  levels of
outstanding  loans,  and  known  and  inherent  risks in the  nature of the loan
portfolio.  Based on this review, and taking into account considerations of loan
quality  and the net  recovery  position,  management  determined  that  further
additions to the allowance for loan loss were not necessary at this time.

Non-Interest Income

Non-interest  income,  exclusive  of  security  gains,  increased  by $57,000 to
$644,000 for the three months ended September 30, 1999, compared to $587,000 for
the three months ended September 30, 1998. This increase was primarily caused by
an increase in trust fees of $61,000.

Trust fees increased by $61,000,  or 25.0%, for the three months ended September
30, 1999 compared to the same period in 1998 due to an increase in trust assets.

Deposit fees decreased by $3,000,  or 1.3%, for the three months ended September
30, 1999,  compared to the three months ended September 30, 1998,  primarily due
to a reduction in overdraft fees.

Other income for the three  months ended  September  30, 1999,  was $89,000,  an
increase of 18.7%,  from $75,000 for the three months ended  September 30, 1998,
primarily due to increases in ATM fees,  safe deposit fees,  wire transfer fees,
and debit card fees.

Net gains on sales of  investments  decreased  to $80,000  for the three  months
ended  September  30,  1999,  compared  to $268,000  in the three  months  ended
September 30, 1998. The decrease was due to relatively  higher interest rates in
1999, resulting in less opportunity to restructure the investment portfolio.

Non-Interest Expense

Salaries  and benefits  expense  totaled  $2,207,000  for the three months ended
September  30,  1999,  compared  with  $1,854,000  for the  three  months  ended
September  30,  1998,  an  increase  of $353,000  or 19.0%.  This  increase  was
primarily  the result of new hires,  to support the overall  growth of the bank,
and annual salary increases.

Occupancy  expense was $648,000 for the three months ended  September  30, 1999,
compared  with  $535,000  for the three  months ended  September  30,  1998,  an
increase of $113,000 or 21.1%.  The increase was  primarily  due to the addition
and renovation of new  facilities  for the bank's  accounting and loan servicing
departments,  executive  office  space,  commercial  lending  offices,  customer
service center, and the Westford branch.

Advertising and public relations expenses decreased by $13,000, or 9.5%, for the
three months ended  September 30, 1999 compared to the same period in 1998.  The
decrease  is due  to  timing  of  expenses,  as  advertising  expenditures  have
increased for the nine months ended September 30, 1999, as compared to the prior
year period.

Office and data processing  supplies expense increased by $15,000, or 18.1%, for
the three months  ended  September  30, 1999  compared to the same period in the
prior year. The increase was primarily due to overall growth of the bank.

Audit,  legal and other professional  expenses decreased by $134,000,  or 41.4%,
for the three months ended September 30, 1999 compared to the prior year period,
primarily due to consulting fees incurred in 1998 relating to the implementation
of certain tax strategies.

Trust,  professional and custodial expenses increased by $17,000,  or 21.3%, for
the three  months  ended  September  30,  1999 as compared to the same period in
1998.  The increase was due to an increase in trust assets under  management  as
well as additional services provided by the trust department.

                                       20



The company's  effective tax rate for the three months ending September 30, 1999
was 26.5%  compared to 21.6% for the three  months  ended  September  30,  1998.
During the third  quarter of 1998,  the company  implemented  certain tax saving
strategies. The effective rate for the three months ended September 30, 1998 was
lower due to  accelerating  these  strategies  to achieve  full year benefit for
1998.

ITEM 3 - Quantitative and Qualitative Disclosures about Market Risk

The company's primary market risk is interest rate risk,  specifically,  changes
in the interest rate environment. The bank's investment committee is responsible
for establishing  policy guidelines on acceptable exposure to interest rate risk
and liquidity.  The investment  committee is comprised of certain members of the
Board of  Directors  and  certain  members  of senior  management.  The  primary
objectives of the company's  asset/liability policy is to monitor,  evaluate and
control the bank's  interest rate risk,  as a whole,  within  certain  tolerance
levels while ensuring adequate  liquidity and adequate  capital.  The investment
committee  establishes  and  monitors  guidelines  for the net  interest  margin
sensitivity,  equity  to  capital  ratios,  liquidity,  Federal  Home  Loan Bank
borrowing capacity and loan to deposit ratio. The asset/liability strategies are
reviewed regularly by management and presented and discussed with the investment
committee on at least a quarterly  basis.  The  asset/liability  strategies  are
revised based on changes in interest rate levels,  general economic  conditions,
competition in the marketplace,  the current  position of the bank,  anticipated
growth of the bank and other factors.

One of the  principal  factors in  maintaining  planned  levels of net  interest
income is the  ability to design  effective  strategies  to manage the impact of
changes in  interest  rates on future net  interest  income.  The  balancing  of
changes in interest income from interest  earning assets and interest expense of
interest  bearing  liabilities  is  accomplished   through  the  asset/liability
management  program.  The bank's simulation model analyzes various interest rate
scenarios.  Variations in the interest rate environment affect numerous factors,
including prepayment speeds,  reinvestment rates, maturities of investments (due
to call provisions), and interest rates on various asset and liability accounts.
The  investment  committee   periodically  reviews  guidelines  or  restrictions
contained in the asset/liability policy and adjusts them accordingly. The bank's
current  asset/liability  policy is designed to limit the impact on net interest
income to 10% in the 24 month period  following the date of the  analysis,  in a
rising and falling rate shock analysis of 100 and 200 basis points.

Management  believes  there have been no material  changes in the interest  rate
risk reported in the  company's  Annual Report on Form 10-KSB for the year ended
December 31, 1998.
