           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS


Results of Operations

The  corporation's  discussion  and analysis of the  significant  changes in the
results  of  operations,  capital  resources  and  liquidity  presented  in  the
accompanying  consolidated  financial  statements  for the  Registrant,  and its
wholly-owned  subsidiaries,  Adams County National Bank and Pennbanks  Insurance
Company, follow. The corporation's consolidated statement of financial condition
and results of operations consist  principally of the bank's financial condition
and results of operations.  This discussion  should be read in conjunction  with
the corporation's 2002 Annual Report to Shareholders.  Current  performance does
not guarantee,  assure, and is not necessarily indicative of similar performance
in the future.

In addition to historical information,  this Form 10-Q contains  forward-looking
statements.  From time to time,  the  corporation  may  publish  forward-looking
statements  relating  to such  matters  as  anticipated  financial  performance,
business  prospects,  technological  developments,  new  products,  research and
development  activities and similar matters.  The Private Securities  Litigation
Reform Act of 1995  provides a safe harbor for  forward-looking  statements.  In
order to comply with the terms of the safe harbor,  the corporation notes that a
variety of factors could cause the  corporation's  actual results and experience
to  differ  materially  from  the  anticipated  results  or  other  expectations
expressed  in  the  corporation's  forward-looking  statements.  The  risks  and
uncertainties  that may  affect the  operations,  performance,  development  and
results of the  corporation's  business include the following:  general economic
conditions, including their impact on capital expenditures;  business conditions
in the banking industry; the regulatory environment; rapidly changing technology
and  evolving  banking  industry  standards;   competitive  factors,   including
increased   competition   with  community,   regional  and  national   financial
institutions;  new  service  and  product  offerings  by  competitors  and price
pressures; and similar items.

Three months ended March 31, 2003 compared to three months ended March 31, 2002

Net Income for the three month period ending March 31, 2003 was  $2,467,000,  up
$193,000 from the first  quarter of 2002.  Net interest  income was down,  total
other income was up and other expense was up. The first quarter  increase is due
to securities gain and gain on sale of other real estate.  Net income per share,
for the first quarter,  was $.45, compared to the $.42 earned in the same period
in 2002. For the three month period  (annualized) in 2003, the return on average
assets  and  return on  average  equity  were  1.30% and  14.14%,  respectively,
compared to 1.47% and 14.55%, respectively for 2002.

An  explanation  of the factors and trends that caused  changes  between the two
periods, by major earnings category, follows.

Total interest  income for the first three month period of 2003 was  $9,565,000,
up $156,000 or 1.6% above the $9,409,000  earned in the same period of 2002. The
$156,000 increase in interest income was due to a rapid growth in earning assets
in the  securities  portfolio  during 2003.  The average yield on earning assets
declined 114 basis points  compared to the same quarter in 2002. In an effort to
manage interest rate risk, the corporation  continues to lower interest rates on
transaction accounts and keep securities maturities short. Income from loans was
down  approximately  $214,000 due to lower interest rates while security  income
was up approximately $366,000 due to greater volume of securities.



Total interest  expense for the first three month period of 2003 was $3,696,000,
up $383,000 or 11.6% from the  $3,313,000  incurred for the same period in 2002.
The  $383,000  increase  in  interest  expense  was  due to  successful  deposit
promotions  and increased  borrowing.  Because the increase in interest  expense
exceeded  the  increase  in  interest  income,  net  interest  income  decreased
$227,000.

Total other income for the first three month period of 2003 at  $1,939,000,  was
$905,000  greater than the same quarter in 2002.  The  following are the primary
causes of the 88% increase in other income:

o        A $55,000 increase in overdraft charges as the overdraft privilege
         program continues to be successful.

o        Gain on sale of other real estate.  The former Carroll Valley Office
         was sold in March of 2003, and a gain of $222,000 was recognized.

o        Realized gains on securities of $450,000.  Short term securities with
         terms of approximately 12 to 18 months were sold for gains, and the
         proceeds reinvested at terms of 24 to 30 months at higher rates.  Not
         all of the funds were reinvested at higher rates, but the average
         return ended up greater than before the sale.

o        Additional income from bank owned life insurance of approximately
         $50,000.

Since  interest  margins  continue to narrow,  the main cause of  increased  net
earnings can be traced to the other income category.

Total other expense for the first three month period of 2003 was $4,302,000,  up
$510,000  from the  $3,792,000  incurred  for the  first  quarter  of 2002.  The
following are the primary causes of the 13% increase in other expense:

o        A $301,000 or 14% increase in salaries and benefits caused by a
         continuation of staffing efforts connected with a new branch
         in Dillsburg, PA, and upgrading of loan personnel.

o        A $120,000 increase in premises and equipment expense. This increase
         was spread across the entire category and not confined to a specific
         area.

o        An $89,000 increase spread across the entire other expense category.

The provision for income taxes in the first quarter  decreased  $25,000 due to a
higher level of tax-free income and low income housing tax credits.

OVERVIEW OF THE BALANCE SHEET

The changes in the balance  sheet have been driven by strong  growth in interest
bearing  transaction  accounts and  borrowings.  The  following  are some of the
results:




o        Total investment securities were $355,978,000, at March 31, 2003, an
         increase of $143,127,000  or 67% since March 31, 2002.  Securities have
         increased  from 34% of total  assets to 45% of total  assets,  of these
         securities,  $20,000,000  mature  within  seven  months with a total of
         $72,100,000  maturing within two years. These funds should be available
         for reinvestment when interest rates rise.


o        Total deposits have grown from $511,759,000, at March 31, 2002, to
         $604,793,000,  at March 31, 2003,  an increase of  $93,034,000  or 18%.
         Approximately  $72,600,000  of those  deposits are called classic money
         market.  At March 31,2002,  the corporation had none of these accounts.
         They are  transaction  accounts,  which  will  require  a  movement  of
         interest rates, similar to general money market rates, when the economy
         improves. In addition,  borrowings have increased from $37,400,000,  at
         March  31,  2002,  to  $108,600,000,   at  March  31,  2003.  Of  these
         $75,000,000  are  term  borrowings  ranging  from  two to ten  years in
         maturity.

o        Accumulated other comprehensive income has increased from a negative
         $508,000,  at March 31, 2002,  to a positive  $3,963,000,  at March 31,
         2003. This indicates the after tax effect in the change in market value
         of the available for sale securities portfolio. This shift enhances the
         corporation's  ability to reposition the portfolio for income  purposes
         as interest  rates rise. As these  securities  come closer to maturity,
         they can be sold and terms lengthened to obtain higher yields.

Net Yield on Earning Assets                                      3.28%     4.19%

Net Yield on Earning Assets is the difference,  stated in  percentages,  between
the interest  earned on loans and other  investments  and the  interest  paid on
deposits and other sources of funds.  The Net Yield on Earning  Assets is one of
the best  analytical  tools available to demonstrate the effect of interest rate
changes on the corporation's earning capacity.

The Net Yield on Earning Assets, for the first three months of 2003, was down 91
basis points compared to the same period in 2002. Yields on loans and securities
have changed more  rapidly than deposit  rates as interest  rates in the general
economy have  remained at record low levels after falling  dramatically  in 2001
and 2002.

The Reserve for Possible Loan Losses at March 31, 2003 was $3,849,000  (1.01% of
Total Loans),  an increase of $161,000 from $3,688,000 (1.01% of Total Loans) at
the end of the first quarter of 2002.  Loans past due 90 days and still accruing
were $1,265,000 and non-accrual  loans were $424,000,  as of March 31, 2003. The
ratio of non-performing  assets plus other real estate owned to total assets was
..28%, at March 31, 2003.  All  properties  are carried at the lower of market or
book value and are not considered to represent significant threat of loss to the
bank.

Loans past due 90 days and still  accruing  were  $1,379,000,  at year end 2002,
while  non-accruals were $1,037,000.  The bulk of the corporation's  real estate
loans are in  residential  mortgages.  Management  believes  that  internal loan
review  procedures  will be effective in  recognizing  and  correcting  any real
estate  lending  problems  that may occur due to  current  economic  conditions.
Interest not accrued,  due to an average of $730,000 in non-accrual  loans,  was
approximately $10,000 for the first quarter of 2003.

The bank  considers  a loan  impaired  when,  based on current  information  and
events,  it is probable that a lender will be unable to collect all amounts due.
We measure  impaired  loans based on the present  value of expected  future cash
flows,  discounted  at the loan's  effective  interest  rate,  or as a practical
expedient,  at the  loan's  observable  market  price or the  fair  value of the
collateral if the loan is collateral  dependent.  If the measure of the impaired
loan is less than its recorded  investment a lender must recognize an impairment
by creating, or adjusting,  a valuation allowance with a corresponding charge to
loan loss  expense.  The  corporation  uses the cash basis  method to  recognize
interest income on loans that are impaired.  All of the  corporation's  impaired
loans were on a non-accrual status for all reported periods.

CAPITAL MANAGEMENT

Total  Shareholders'  Equity was  $71,607,000,  at March 31,  2003,  compared to
$62,938,000,  at March 31, 2002,  an increase of  $8,669,000  or 13.8% over that
period.  The ratio of Total  Shareholders'  Equity to Total Assets was 9.54%, at
December 31, 2002,  10.17%, at March 31, 2002, and 9.04%, at March 31, 2003. The
total risk-based capital ratio was 14.53%, at March 31, 2003. The leverage ratio
was 8.65%,  at March 31,  2003,  and  10.16%,  during  the same  period in 2002.
Capital growth of $4,471,000  reflects a change in other  comprehensive  income,
consisting mainly of unrealized  security gains, but the remainder,  $4,198,000,
was generated internally through retained earnings.

LIQUIDITY AND INTEREST RATE SENSITIVITY

Management believes that the corporation's liquidity is adequate.  Liquid assets
(cash  and due  from  banks,  federal  funds  sold,  money  market  instruments,
available  for  sale  securities  and  held to  maturity  investment  securities
maturing within one year) were 45% of total assets, at March 31, 2003. This





mix of assets would be readily available for funding any cash  requirements.  In
addition, the Bank has an approved line of credit of $343,284,000 at the Federal
Home Loan Bank of Pittsburgh with $75,000,000 outstanding at March 31, 2003.

As of March 31,  2003,  the  cumulative  asset  sensitive  gap was 4.2% of total
assets at one month, 9.0% at six months, and 17.0% at one year.  Adjustable rate
mortgages,  which have an annual  interest rate cap of 2%, are  considered  rate
sensitive.  Twenty-five (25%) percent of passbook and statement savings, NOW and
money market deposit accounts are calculated to reprice overnight. The remaining
75% are carried in the over 5-year category.

Other than the construction of a new operations  center,  costing  approximately
$7,000,000  over the next 18  months,  there  are no known  trends  or  demands,
commitments, events or uncertainties that will result in, or that are reasonably
likely to result in,  liquidity  increasing  or  decreasing in any material way.
Aside from those matters described above,  management does not currently believe
that  there are any known  trends or  uncertainties  that  would have a material
impact on future  operating  results,  liquidity or capital  resources nor is it
aware of any current  recommendations by the regulatory  authorities,  which, if
they were to be  implemented,  would have such an effect,  although  the general
cost of  compliance  with  numerous  and  multiple  federal  and state  laws and
regulation  does  have and in the  future  may  have a  negative  impact  on the
corporation's results of operations.




                                     ITEM 3

            QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Management  monitors and  evaluates  changes in market  conditions  on a regular
basis.  Based upon the most recent review  management has determined  that there
have been no  material  changes  in market  risks  since year end.  For  further
discussion of year end information, refer to the annual report.


                                     ITEM 4

                             CONTROLS AND PROCEDURES

Within the 90 days prior to the date of this report, the corporation carried out
an  evaluation,  under  the  supervision  and  with  the  participation  of  the
corporation's  management,  including the corporation's Chief Financial Officer,
of the effectiveness of the design and operation of the corporation's disclosure
controls  and  procedures  pursuant  to the  Securities  Exchange  Act  of  1934
("Exchange  Act") Rule 13a-14.  Based upon that  evaluation,  the  corporation's
Chief Executive  Officer along with the  corporation's  Chief Financial  Officer
concluded  that  the  corporation's   disclosure  controls  and  procedures  are
effective  in timely  alerting  them to  material  information  relating  to the
corporation (including its consolidated subsidiaries) required to be included in
the corporation's  periodic SEC filings.  There have been no significant changes
in  the  corporation's  internal  controls  or  in  other  factors  which  could
significantly  affect  these  controls  subsequent  to the date the  corporation
carried out its evaluation.  Disclosure  controls and procedures are corporation
controls  and other  procedures  that are  designed to ensure  that  information
required to be  disclosed  by the  Corporation  in the reports  that it files or
submits under the Exchange Act is recorded,  processed,  summarized and reported
within the time periods specified in the SEC's rules and forms.
