                                  EXHIBIT 10.2
                     CHANGE OF CONTROL AGREEMENT - J. WEAVER

THIS CHANGE OF CONTROL AGREEMENT (hereinafter "Agreement") is made as of the 1st
day of October, 1997, between PeoplesBank, A Codorus Valley Company, a
Pennsylvania banking institution (the "Bank"), Codorus Valley Bancorp, Inc., a
Pennsylvania business corporation (the "Corporation") and Jann A. Weaver, an
adult individual (the "Executive").

WHEREAS, the Corporation employs the Executive as its Assistant Secretary and
Assistant Treasurer, and the Bank employs the Executive as its Senior Vice
President and Chief Financial Officer; and

WHEREAS, the Executive has provided valued service to the Corporation and the
Bank in the past; and

WHEREAS, in recognition of the valued past and present service of the Executive,
the Bank and the Corporation desire to provide incentive for continued valued
service and grants to the Executive the benefits set forth herein upon the
occurrence of a Change of Control (as defined herein); and

WHEREAS, the purpose of this Agreement is to define certain severance benefits
that will be paid by the Bank and the Corporation in the event of a Change of
Control (as defined herein). This Agreement is not intended to affect the terms
of the Executive's employment at will, in the absence of a Change of Control (as
defined herein) of the Bank and the Corporation. Accordingly, although this
Agreement will take effect upon Executive as a binding legal obligation of the
Bank and the Corporation, it will become operative only upon a Change in
Control, as that concept is defined below.

NOW THEREFORE, in consideration of the Executive's service to the Corporation
and the Bank and of the mutual covenants, undertakings and agreements set forth
herein and intending to be legally bound hereby, the parties agree as follows:

     1. TERM The initial term of this Agreement shall be deemed to have
commenced on October 1, 1997, such that the initial term shall continue for a
period of fifteen (15) months until December 31, 1998. Each term thereafter
shall consist of a twelve (12) month period which shall begin on January 1, of
each year. On the initial renewal date of January 1, 1999, and on each
subsequent renewal date, this Agreement shall be automatically renewed for an
additional twelve (12) month term, unless the Corporation and/or the Bank
provide the Executive with written notice of non-renewal at least sixty (60)
days prior to any such renewal date. For example: (1) if the Corporation and/or
the Bank do not provide written notice of non-renewal at least sixty (60) days
prior to January 1, 1999, the Agreement will automatically renew for an
additional twelve (12) month period terminating on December 31, 1999; or (2) If
the Corporation and/or the Bank provide written notice of non-renewal on
November 1, 1998, which is at least sixty (60) days prior to January 1, 1999,
the Agreement will terminate on December 31, 1998.

     2. DEFINITION OF CHANGE OF CONTROL. For purposes of this Agreement, the
term "Change of Control" shall mean: A change in control of a nature that would
be required to be reported in response to Item 6(e) of Schedule 14A of
Regulation 14A and any successor rule or regulation promulgated under the
Securities Exchange Act of 1934 (the "Exchange Act"); provided that, without
limitation, such a change in control shall be deemed to have occurred if (a) any
"person" (as such term is used in Sections 13(d) and

                                       15

<PAGE>

14(d) of the Exchange Act), other than the Corporation or any "person" who on
the date hereof is a director or officer of the Corporation is or becomes the
"beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly
or indirectly, of securities of the Corporation representing twenty-five percent
(25%) or more of the combined voting power of the Corporation's then outstanding
securities, or (b) during any period of two consecutive years during the term of
this Agreement, individuals who at the beginning of such period constitute the
Board of Directors of the Bank or Corporation cease for any reason to constitute
at least a majority thereof, unless the election of each director who was not a
director at the beginning of such period has been approved in advance by
directors representing at least two-thirds of the directors then in office who
were directors at the beginning of the period, or (c) the sale or transfer of
all or substantially all of the Bank or Corporation's assets.

     3. DEFINITION OF DATE OF CHANGE OF CONTROL. For purposes of this Agreement,
the date of Change of Control shall mean:

     (a) the first date on which a single person and/or entity, or group of
affiliated persons and/or entities, acquire the beneficial ownership of
twenty-five percent (25%) or more of the Corporation's voting securities, or

     (b) the date of the transfer of all or substantially all of the Bank or
Corporation's assets, or

     (c) the date on which a merger, consolidation or combination is
consummated, as applicable, or

     (d) the date on which individuals who formerly constituted a majority of
the Board of Directors of the Bank or Corporation, ceased to be a majority.

     4. PAYMENTS UPON TERMINATION. If a Change of Control (as defined herein)
occurs, the Executive shall receive a lump sum amount equal to his current
"Annual Direct Salary", as of the Date of the Change of Control (as defined
herein). Annual Direct Salary shall be defined herein as the fixed, gross, base
annual salary paid to the Executive in installments at such time as the Bank and
Corporation customarily pays its other senior officers and shall not include any
benefits, bonuses, incentives or other compensation.

     5. UNAUTHORIZED DISCLOSURE. During the term of this Agreement, or at any
later time, the Executive shall not, without the written consent of the Board of
Directors of the Corporation or Bank or a person authorized thereby, knowingly
disclose to any person, other than an employee of the Corporation or Bank or a
person to whom disclosure is reasonably necessary or appropriate in connection
with the performance by the Executive of his duties as an executive of the
Corporation or Bank, any material confidential information obtained by him while
in the employ of the Corporation or Bank with respect to any of the Corporation
or Bank's services, products, improvements, formulas, designs or styles,
processes, customers, methods of business or any business practices the
disclosure of which could be or will be materially damaging to the Corporation
or Bank provided, however, that confidential information shall not include any
information known generally to the public (other than as a result of
unauthorized disclosure by the Executive or any person with the assistance,
consent or direction of the Executive) or any information of a type not
otherwise considered confidential by persons engaged in the same business or a
business similar to that conducted by the Corporation or Bank or any information
that must be disclosed as required by law.

                                       16

     6. RESTRICTIVE COVENANT. The Executive covenants and agrees that the
Executive shall not directly or indirectly, within the marketing area of the
Bank (defined as an area within twenty-five (25) of the registered office of the
Bank), enter into or engage generally in direct or indirect competition with the
Corporation or Bank or any subsidiary of the Corporation, either as an
individual on his own or as a partner or joint venturer, or as a director,
officer, greater than five percent (5%) shareholder, employee, agent,
independent contractor, lessor or creditor of or for any person, for a period of
six (6) months after the date of termination of his employment if the
Executive's employment is terminated as a result of a Change of Control (as
defined herein). The existence of any claim or cause of action of the Executive
against the Corporation or Bank, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by the Corporation
or Bank of this covenant. The Executive agrees that any breach of the
restrictions set forth in this Agreement will result in irreparable injury to
the Corporation or Bank for which it shall have no adequate remedy at law and
the Corporation or Bank shall be entitled to injunctive relief in order to
enforce the provisions hereof. In the event that this paragraph shall be
determined by any court of competent jurisdiction to be unenforceable in part by
reason of it being too great a period of time or covering too great a
geographical area, it shall be in full force and effect as to that period of
time or geographical area determined to be reasonable by the court.

     7. DAMAGES FOR BREACH OF CONTRACT. In the event of a breach of this
Agreement by either the Corporation, Bank or the Executive resulting in damages

breaching the Agreement only those damages as set forth herein. In no event
shall any party be entitled to the recovery of attorney's fees or costs.
