Item 5.03 Amendments to Articles of  Incorporation  or Bylaws;  Change in Fiscal
          Year.

     On February  21,  2006,  the Board of  Directors  (the  "Board") of Penseco
Financial Services Corporation (the "Company") voted to amend the By-laws of the
Company (the "Bylaws") by: (i) amending  Article II, Section 2.1 to provide that
the annual  meetings of the  shareholders  of the Company will be held once each
calendar year at a date and time determined by the Board;  (ii) amending Article
II,  Sections  2.2  and  2.3  and  adding  a new  Section  2.4 to  require  that
shareholders  provide  advance  notice to the  Company in order to (a)  nominate
individuals for election to the Board of Directors of the Company at meetings of
the stockholders, or (b) submit proposals for any new business to be taken up at
meetings of the stockholders;  (iii) amending Article II, Section 2.3 to provide
that only the  President of Company,  the Chairman of the Board or the Board can
call a special  meeting of the  shareholders  of the  Company;  and (iv)  adding
Article IV, Section 4.5 to provide for the creation of a Compensation  Committee
of the Board. These amendments were effective immediately.

     In addition,  the Board approved,  subject to the approval of the Company's
shareholders,  an amendment to the Articles of  Incorporation of the Company and
the addition of Article II,  Section 2.9 of the Bylaws,  in each case to provide
that  shareholders  may not take any  action  by  written  consent  in lieu of a
meeting and may only take any actions at a duly called meeting of  shareholders.
The  Board  recommended  that the  shareholders  of the  Company  approve  these
amendments to the Articles and Bylaws at the 2006 annual meeting of shareholders
to be held on May 2, 2006.

     The full text of the amended  and  restated  By-laws is attached  hereto as
Exhibit 3(ii).
