                          CODORUS VALLEY BANCORP, INC.

ITEM 1.01 ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

          On November 4, 2005, Codorus Valley Bancorp, Inc. (the "Company")
     entered into a Rights Agreement with Wells Fargo Bank, N.A., as Rights
     Agent (the "Rights Agreement"). Pursuant to the Rights Agreement, the
     Company declared a dividend distribution of one Right for each outstanding
     share of common stock, par value $2.50 per share (the "Common Stock"), of
     the Company to shareholders of record at the close of business on November
     7, 2005 (the "Record Date"). Each Right entitles the registered holder to
     purchase from the Company one share of Common Stock at a price of $150.00
     per share (the "Purchase Price"), subject to adjustment. The Purchase Price
     shall be paid, at the option of the holder, in cash or shares of Common
     Stock having an equivalent value. The description and terms of the Rights
     are set forth in a Rights Agreement.

          Initially, the Rights will be evidenced by all Common Stock
     certificates representing shares then outstanding, and no separate Rights
     certificates will be distributed. The Rights will separate from the Common
     Stock and a Distribution Date will occur upon the earlier of (i) 10
     business days following a public announcement that a person or a group of
     affiliated or associated persons (an "Acquiring Person") has acquired, or
     obtained the right to acquire, beneficial ownership of 20% or more of the
     outstanding shares of Common Stock (the "Stock Acquisition Date"), or (ii)
     10 business days following the commencement of a tender offer or exchange
     offer that would result in a person or group beneficially owning 20% or
     more of such outstanding shares of Common Stock. Until the Distribution
     Date, (i) the Rights will be evidenced by such Common Stock certificates
     and will be transferred with and only with such Common Stock certificates,
     (ii) new Common Stock certificates issued after the Record Date will
     contain a notation incorporating the Rights Agreement by reference, and
     (iii) the surrender for transfer of any certificates for Common Stock
     outstanding will also constitute the transfer of the Rights associated with
     the Common Stock represented by such certificates. As soon as practicable
     following the Distribution Date, separate certificates evidencing the
     Rights ("Right Certificates") will be mailed to holders of record of the
     Common Stock as of the close of business on the Distribution Date and,
     thereafter, such separate Rights Certificates alone will evidence the
     rights.

          The Rights are not exercisable until the Distribution Date and will
     expire at the close of business on November 4, 2015, unless earlier
     redeemed by the Company as described below.

          In the event that (i) the Company is the surviving corporation in a
     merger or the acquiring corporation in a statutory share exchange with an
     Acquiring Person and its Common Stock is not changed or exchanged, (ii) an
     Acquiring Person engages in certain self-dealing transactions with the
     Company, (iii) a person (other than the Company and its affiliates) becomes
     the beneficial owner of 20% or more of the then outstanding shares of
     Common Stock, or (iv) during a time that there is an Acquiring Person, one
     or more specified events occur that result in such Acquiring Person's
     ownership interest in the Company being increased by more than 1%, the
     Rights Agreement provides that proper provision shall be made so that each
     holder of a Right will thereafter have the right to receive, upon exercise,
     Common Stock (or, in certain circumstances, cash, property or other
     securities of the Company) having a value equal to two (2) times the
     exercise price of the Right.


                                        2



          For example, at an exercise price of $150.00 per Right, each Right not
     owned by an Acquiring Person (or by certain related parties and transferees
     of the Acquiring Person) following an event set forth in the preceding
     paragraph would entitle its holder to purchase $300.00 worth of Common
     Stock (or other consideration, as noted above) for $150.00. Assuming that
     the Common Stock had a per share value of $150.00 at such time, the holder
     of each valid Right would be entitled to purchase two shares of Common
     Stock for $150.00.

          In the event that, at any time following the Distribution Date, (i)
     the Company is acquired in a merger, statutory share exchange or other
     business combination transaction in which the Company is not the surviving
     corporation, (ii) the Company engages in a merger or other business
     combination transaction with another person in which the Company is the
     surviving corporation, but in which its Common Stock is changed or
     exchanged, or (iii) 50% or more of the Company's assets or earning power is
     sold or transferred, the Rights Agreement provides that proper provision
     shall be made so that each holder of a Right shall thereafter have the
     right to receive, upon exercise of the Right, common stock or other
     consideration of the acquiring company having a value equal to two (2)
     times the exercise price of the Right.

          Notwithstanding any of the foregoing, following the occurrence of any
     of the events set forth in the preceding paragraph and the third preceding
     paragraph (the "Triggering Events"), any Rights that are, or (under certain
     circumstances specified in the Rights Agreement) were, beneficially owned
     by any Acquiring Person shall immediately become null and void. Also, under
     no circumstances may a Right be exercised following the occurrence of an
     event set forth in clause (iii) of the third preceding paragraph prior to
     expiration of the Company's right of redemption.

          The Purchase Price payable, and the number of shares of Common Stock
     or other securities or property issuable, upon exercise of the Rights are
     subject to adjustment from time to time to prevent dilution (i) in the
     event of a stock dividend on, or a subdivision, combination or
     reclassification of, the Common Stock, (ii) upon the grant to holders of
     the Common Stock of certain rights or warrants to subscribe for Common
     Stock or convertible securities at less than the then current market price
     of Common Stock, or (iii) upon the distribution to holders of the Common
     Stock of evidences of indebtedness or assets (excluding regular quarterly
     cash dividends) or of subscription rights or warrants (other than the
     Rights).

          No adjustment in the Purchase Price will be required until cumulative
     adjustments amount to at least 1% of the Purchase Price. No fractional
     shares will be issued upon exercise of a Right and, in lieu thereof, an
     adjustment in cash will be made based on the market price of the Common
     Stock on the last trading date prior to the date of exercise.

          The term "Continuing Directors" means any member of the Board of
     Directors of the Company who was a member of the Board prior to the date of
     the Rights Agreement, and any person who is subsequently elected to the
     Board if such person is recommended or approved by a majority of the
     Continuing Directors, but shall not include an Acquiring Person, or any
     affiliate or associate of an Acquiring Person, or any representative of an
     Acquiring Person or of an affiliate or associate of an Acquiring Person.

          At any time until ten (10) business days following the Stock
     Acquisition Date or prior to November 4, 2015, the Board of Directors may
     cause the Company to redeem the Rights in whole, but not in part, at a
     price of $0.001 per Right (the "Redemption Price"); provided, however, if
     the


                                        3



     Board of Directors of the Company authorizes redemption of the Rights in
     either of the circumstances set forth in clauses (i) and (ii) below, then
     there must be at least five Continuing Directors then in office and such
     authorization requires the concurrence of a majority of such Continuing
     Directors: (i) such authorization occurs on or after the time a person or
     group acquires beneficial ownership of 20% or more of the outstanding
     Common Stock, or (ii) such authorization occurs on or after the date of a
     change in a majority of the directors resulting from a proxy solicitation
     if the solicitor (or any participant in the solicitation) indicates an
     intention to become an Acquiring Person or to cause a Triggering Event.
     Thereafter, the Company's right of redemption may be reinstated if an
     Acquiring Person reduces his beneficial ownership to 10% or less of the
     outstanding shares of Common Stock in a transaction or series of
     transactions not involving the Company and there is then no other Acquiring
     Person.

          Immediately upon the action of the Board of Directors of the Company,
     with, where required, the concurrence of the Continuing Directors, ordering
     redemption of the Rights, the Rights will terminate and the only right of
     the holders of Rights will be to receive the Redemption Price.

          Until a Right is exercised, the holder thereof, as such, will have no
     rights as a stockholder of the Company, including, without limitation, the
     right to vote or to receive dividends.

          The Rights Agreement and related press release are attached hereto as
     Exhibits 4 and 99.1 respectively.
