PART I

The management of Codorus Valley Bancorp, Inc. has made forward-looking
statements in this annual report on Form 10-K. These forward-looking statements
may be subject to risks and uncertainties. Forward-looking statements include
the information concerning possible or assumed future results of operations of
Codorus Valley Bancorp, Inc. and its subsidiaries, PeoplesBank, A Codorus Valley
Company and SYC Realty Company, Inc. Management is making forward-looking
statements when words such as "believes," "expects," "anticipates" or similar
expressions are used in this annual report.

Shareholders should note that many factors some of which are discussed elsewhere
in this report, could affect the future financial results of Codorus Valley
Bancorp, Inc.,its subsidiaries, or the combined company, and could cause those
results to differ materially from those expressed in the forward-looking
statements contained in this annual report on Form 10-K. These factors include:

     o    operating, legal and regulatory risks;
     o    economic, political and competitive forces affecting banking,
          securities, asset management and credit services businesses; and
     o    the risk that management's analysis of these risks and forces could be
          incorrect and/or that the strategies developed to address them could
          be unsuccessful.

Item 1: Business

Codorus Valley Bancorp, Inc. is a Pennsylvania business corporation. It was
incorporated on October 7, 1986. On March 2, 1987, Codorus Valley became a bank
holding company, under the Bank Holding Company Act of 1956. PeoplesBank, A
Codorus Valley Company is its wholly-owned banking subsidiary and SYC Realty
Co., Inc. is its wholly-owned nonbank subsidiary. Codorus Valley's business
consists primarily of managing PeoplesBank, and its principal source of income
has been dividends received from PeoplesBank. On December 31, 1999, Codorus
Valley had total consolidated assets of $291 million, total deposits and other
liabilities of $266 million, and total stockholders' equity of $25 million.

Bank Subsidiary

PeoplesBank, organized in 1934, is a Pennsylvania chartered bank and is not a
member of the Federal Reserve System. PeoplesBank offers a full range of
commercial and consumer banking services through eight full service banking
office locations in York County, Pennsylvania. PeoplesBank also offers trust and
investment services at Codorus Valley Corporate Center located in York,
Pennsylvania. The Federal Deposit Insurance Corporation insures the deposits of
PeoplesBank to the extent provided by law. On December 31,1999, PeoplesBank had
total loans of $207 million and total deposits of $238 million.

PeoplesBank is not dependent on deposits or exposed to loan concentration to a
single customer, or to a small group of customers. Therefore, losses from a
single customer, or small customer group, would not have a material adverse
effect on the financial condition of PeoplesBank. At year end 1999,

                                        3



there were three concentrations of loans by industry that exceeded 10% of total
loans, as follows: commercial facility leasing, 16.1%; residential facility
leasing, 10.9%; and real estate development, 10.6%, compared to 17.2%, 11.8% and
10.4%, respectively, at year end 1998.

In 1998, PeoplesBank created SYC Settlement Services, Inc., as a wholly-owned
subsidiary, to provide real estate settlement services. SYC Settlement Services,
Inc. began operations in January 1999.

In 1999, PeoplesBank created SYC Insurance Services, Inc., as a wholly-owned
subsidiary, to facilitate the sale of investment products through a third-party
marketing arrangement. SYC Insurance, inactive during 1999, began operations in
January 2000.

Nonbank Subsidiary

On June 20, 1991, SYC Realty Company, Inc. was incorporated as a wholly-owned
subsidiary of Codorus Valley Bancorp, Inc. Codorus Valley created this nonbank
subsidiary primarily for the purpose of disposing of selected properties
obtained from PeoplesBank in satisfaction of debts previously contracted. SYC
Realty commenced business operations in October 1995. To date, the financial
impact of this subsidiary's operations on Codorus Valley and PeoplesBank has
been immaterial.

Competition

The banking industry in PeoplesBank's service area, principally York County,
Pennsylvania, is extremely competitive. PeoplesBank competes with commercial
banks and other financial service providers such as thrifts, credit unions,
consumer finance companies, investment firms, and mortgage companies. Some
financial service providers operating in PeoplesBank's service area operate on a
national and regional scale and possess resources greater than those of
PeoplesBank.

Supervision and Regulation

Codorus Valley Bancorp, Inc. is registered as a bank holding company and is
subject to the regulations of the Board of Governors of the Federal Reserve
System under the Bank Holding Company Act of 1956. The Bank Holding Company Act
requires bank holding companies to file periodic reports with and are subject to
examination by the Federal Reserve. The Federal Reserve issued regulations under
the Bank Holding Company Act that require a bank holding company to serve as a
source of financial and managerial strength to its subsidiary banks. As a
result, the Federal Reserve, pursuant to such regulations, may require Codorus
Valley to stand ready to use its resources to provide adequate capital funds to
PeoplesBank during periods of financial stress or adversity.

The Bank Holding Company Act prohibits Codorus Valley from acquiring: direct or
indirect control of more than 5% of the outstanding voting stock of any bank, or
substantially all of the assets of any bank, or merging with another bank
holding company, without the prior approval of the Federal Reserve. The
Pennsylvania Department of Banking also must approve any similar consolidation.
Pennsylvania law permits Pennsylvania bank holding companies to control an
unlimited number of banks.


                                        4


The Bank Holding Company Act restricts Codorus Valley to engaging in activities
that the Federal Reserve has found to be closely related to banking, and which
are expected to produce benefits for the public that will outweigh any
potentially adverse effects. To this end, the Bank Holding Company Act prohibits
Codorus Valley from: engaging in most nonbanking businesses, or acquiring
ownership or control of more than 5% of the outstanding voting stock of any
company engaged in a nonbanking business, unless the Federal Reserve has
determined that the nonbanking business is closely related to banking. Under the
Bank Holding Company Act, the Federal Reserve may require a bank holding company
to end a nonbanking business if it constitutes a serious risk to the financial
soundness and stability of any bank subsidiary of the bank holding company.

The operations of PeoplesBank are subject to federal and state statutes
applicable to banks chartered under the banking laws of the Commonwealth of
Pennsylvania and whose deposits are insured by the Federal Deposit Insurance
Corporation.

The FDIC is the primary regulator of PeoplesBank. It regularly examines banks in
such areas as loss reserves, loans, investments, management practices, and other
aspects of operations. These examinations are designed for the protection of
PeoplesBank's depositors rather than Codorus Valley's shareholders. PeoplesBank
must furnish annual and quarterly reports to the FDIC.

Federal and state banking laws and regulations govern, among other things, the
scope of a bank's business, the investments a bank may make, the reserves
against deposits a bank must maintain, the types and terms of loans a bank may
make and the collateral it may take, the activities of a bank with respect to
mergers and consolidations, and the establishment of branches.

The Federal Reserve Act imposes restrictions on a subsidiary bank of a bank
holding company, such as PeoplesBank. The restrictions affect extensions of
credit to the bank holding company and its subsidiaries, investments in the
stock or other securities of the bank holding company and its subsidiaries, and
taking such stock or securities as collateral for loans. The Federal Reserve Act
and Federal Reserve regulations also place limitations and reporting
requirements on extensions of credit by a bank to the principal shareholders of
its parent holding company, among others, and to related interests of such
principal shareholders. In addition, such legislation and regulations may affect
the terms upon which any person becoming a principal shareholder of a holding
company may obtain credit from banks with which the subsidiary bank maintains a
correspondent relationship.

PeoplesBank and the banking industry in general, are affected by the monetary
and fiscal policies of government agencies, including the Federal Reserve.
Through open market securities transactions and changes in its discount rate and
reserve requirements, the Board of Governors of the Federal Reserve exerts
considerable influence over the cost and availability of funds for lending and
investment.

We provide a brief discussion of recent federal agency pronouncements that
affect Codorus Valley and/or PeoplesBank below.


                                        5


On November 12, 1999, President Clinton signed into law the Gramm-Leach-Bliley
Act of 1999, which is also known as the Financial Services Modernization Act.
The act repeals Depression-era banking laws and will permit banks, insurance
companies and securities firms to engage in each others businesses after
complying with conditions and regulations which are yet to be finalized. The act
grants to community banks the power to enter new financial markets as a matter
of right that larger institutions have managed to do on an ad hoc basis. At this
time Codorus Valley has no plans to pursue these additional possibilities.
Management does not believe that the Financial Services Modernization Act will
have an immediate positive or negative material effect on Codorus Valley's
operations. However, the act may result in increased competition from larger
financial service companies, many of who have substantially more financial
resources than Codorus Valley, and now may offer banking services in addition to
insurance and brokerage services.

Periodically, various types of federal and state legislation are proposed that
could result in additional regulation of, and restrictions on, the business of
Codorus Valley and PeoplesBank. It cannot be predicted whether such legislation
will be adopted or, if adopted, how such legislation would affect the business
of Codorus Valley and its subsidiaries. As a consequence of the extensive
regulation of commercial banking activities in the United States, Codorus
Valley's and PeoplesBank's business is particularly susceptible to being
affected by federal legislation and regulations that may increase the cost of
doing business. Except as specifically described above, management believes that
the effect of the provisions of the aforementioned legislation on the liquidity,
capital resources, and results of operations of the Codorus Valley will be
immaterial. Management is not aware of any other current specific
recommendations by regulatory authorities or proposed legislation, which if they
were implemented, would have a material adverse effect upon the liquidity,
capital resources, or results of operations, although the general cost of
compliance with numerous and multiple federal and state laws and regulations
does have, and in the future may have, a negative impact on the Codorus Valley=s
results of operations.

Other information

On December 31, 1999, PeoplesBank had 124 full-time employees and 13 part-time
employees.

Management's Discussion and Analysis of Financial Condition and Results of
Operations of this report.

     November 29, 1993, is for a twenty year term, with four five year term
     options. From inception of the lease through 1997, the minimum annual rent
     was approximately $15,700. For the four year period 1998 through 2001, the
     minimum annual rent will be approximately $17,300. Thereafter, the minimum
     annual rent will increase at three-year intervals.

All of the above properties are located in York County, Pennsylvania and are, in
the opinion of management, adequate for the business purposes of Codorus Valley
and its subsidiaries.

Item 7A: Quantitative and Qualitative Disclosures About Market Risk

Information appearing in the 1999 Annual Report to Stockholders, under the
caption Market Risk Management included in Management's Discussion and Analysis
of Consolidated Financial Condition and Results of Operations, is incorporated
by reference in response to this item and is included on pages 38 and 39 of
Exhibit 13.

Codorus Valley manages interest rate risk primarily through sensitivity
analysis, included on pages 38 and 39 of Exhibit 13. It also uses a gap analysis
as a secondary means for managing interest rate risk. The gap analysis begins by
assigning interest rate sensitive assets and interest rate sensitive liabilities
into future time periods, typically one year, based on a scheduled maturity or
repricing date. Repriceable liabilities are then subtracted from repriceable
assets to determine a difference, or gap. The measurement process relies on many
assumptions such as the amount and timing of repriceable cash flows from
interest rate sensitive assets and liabilities. The following assumptions are
made about repriceable cash flows from interest rate sensitive assets:

     o    variable rate instruments could reprice daily,
     o    adjustable rate instruments reprice at the interest maturity date,
     o    fixed rate loans reprice at their scheduled maturity date and include
          estimated prepayments
     o    fixed rate investment securities, except for mortgage-backed
          instruments, reprice at their scheduled maturity date, or call date if
          more appropriate, and
     o    fixed rate mortgage-backed instruments reprice based on principal
          pay-down estimates.

Generally, interest sensitive liabilities reprice similarly to interest
sensitive assets with the exception of NOW and savings deposits which do not
have scheduled maturities. Technically, NOW and savings balances can be repriced
at any time. Historically, NOW and savings balances have been relatively stable
despite changes in market interest rates. This stability assumption was made in
the current measurement process.

We provide a schedule depicting balance sheet repricing characteristics and an
estimate of gap at December 31, 1999 below. The cumulative gap measure is one
way to measure how a change in market interest rates will impact net interest
income for specific time frames. For example, the cumulative gap in the
"181-365" repricing category represents a one year net liability position of
$100 million or 38 percent of interest earning assets on December 31, 1999. The
liability sensitive gap position implies that over the next year net income will
decrease if market interest rates rise and increase if rates fall. The theory is
that more liabilities will reprice, at higher market interest rates, than the
assets that they fund. Management is presently implementing financial strategies
to reduce Codorus Valley's liability sensitive gap position.

A gap analysis is limited in its usefulness since it represents a one-day
position, which is continually changing and not necessarily indicative of
Codorus Valley's position at any other time. Gap analysis does not consider the
complexity of interest rate relationships and spreads depending on the

                                        9



direction, magnitude and timing of changes in market interest rates.
Additionally, it does not consider the impact of financial strategies that
management could employ.
