I, Ernest J. Sewell, certify that:

      1.    I have reviewed this Quarterly  Report on Form 10-Q of FNB Financial
            Services Corporation;

      2.    Based on my  knowledge,  this  report  does not  contain  any untrue
            statement  of a  material  fact  or omit to  state a  material  fact
            necessary to make the statements made, in light of the circumstances
            under which such  statements  were made, not misleading with respect
            to the period covered by this report;

      3.    Based on my knowledge, the financial statements, and other financial
            information included in this report,  fairly present in all material
            respects,  the financial  condition,  results of operations and cash
            flows of the  registrant  as of, and for,  the periods  presented in
            this report;

      4.    The registrant's  other certifying  officer(s) and I are responsible
            for establishing and maintaining  disclosure controls and procedures
            (as defined in  Exchange  Act Rules  13a-15(e)  and  15d-15(e))  and
            internal  control over  financial  reporting (as defined in Exchange
            Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:

                  (a)  Designed  such  disclosure  controls and  procedures,  or
                  caused such disclosure  controls and procedures to be designed
                  under our  supervision,  to ensure that  material  information
                  relating  to  the  registrant,   including  its   consolidated
                  subsidiaries,  is made  known  to us by  others  within  those
                  entities,  particularly during the period in which this report
                  is being prepared;

                  (b) Designed such internal  control over financial  reporting,
                  or caused such internal control over financial reporting to be
                  designed  under  our   supervision,   to  provide   reasonable
                  assurance regarding the reliability of financial reporting and
                  the preparation of financial  statements for external purposes
                  in accordance with generally accepted accounting principles;

                  (c) Evaluated the effectiveness of the registrant's disclosure
                  controls  and  procedures  and  presented  in this  report our
                  conclusions about the effectiveness of the disclosure controls
                  and  procedures,  as of the end of the period  covered by this
                  report based on such evaluation; and

                  (d)  Disclosed  in this report any change in the  registrant's
                  internal control over financial reporting that occurred during
                  the registrant's  most recent fiscal quarter (the registrant's
                  fourth  fiscal  quarter in the case of an annual  report) that
                  has materially affected, or is reasonably likely to materially
                  affect,  the  registrant's  internal  control  over  financial
                  reporting; and

      5.    The registrant's  other certifying  officer(s) and I have disclosed,
            based  on our  most  recent  evaluation  of  internal  control  over
            financial  reporting,  to the  registrant's  auditors  and the audit
            committee  of  the  registrant's  board  of  directors  (or  persons
            performing the equivalent functions):

                  (a) All significant  deficiencies  and material  weaknesses in
                  the design or  operation of internal  control  over  financial
                  reporting which are reasonably  likely to adversely affect the
                  registrant's ability to record, process,  summarize and report
                  financial information; and

                  (b)  Any  fraud,  whether  or  not  material,   that  involves
                  management or other  employees who have a significant  role in
                  the registrant's internal control over financial reporting.
