Part I

Item 1.  BUSINESS

Description of Business
-----------------------
     The   Commercial   National   Financial   Corporation   (the
"corporation")  was  incorporated   under  the  laws    of    the 
Commonwealth of Pennsylvania on July 1, 1990 and is registered as
a bank holding company under the Bank Holding Company Act of 1956
as  amended.  The corporation is owner of 100% of the outstanding
shares  of  common  stock   of   Commercial   National   Bank  of
Westmoreland  County.  This subsidiary bank and  its  predecessor
have  been providing banking services since 1934. At the  present
time, two (2) banking offices are in operation in Latrobe, two(2)
in  Unity  Township  and one (1) each in Ligonier,  West  Newton,
Greensburg,  Murrysville and Hempfield Township. The  Murrysville
office   began   operations  in  July  of    1996.  An   asset
management/trust  department  was  established  in  1994  and  is
located  in  the  building  that houses  the  Greensburg  banking
office.   All  of  these  offices are within  the  boundaries  of
Westmoreland  County,  Pennsylvania.  In addition,  the  building
which  houses the downtown Latrobe banking office is the location
of  the corporation's and the bank's executive and administrative
offices.  The institution's operations center is located  at  the
Latrobe  Plaza in downtown Latrobe.  This operations center  also
houses  an in-house data processing system.  In November of 1997,
conversion of  the former Plaza  Hotel building officially became
our new corporate  office  center. The new center  will eliminate 
over-crowded work offices, organize work groups and provide space
for growth. Each of  the  banking  offices, except  for  downtown
Latrobe and Greensburg, is  equipped  with twenty-four-hour-a-day
automatic teller machines and one (1) additional  ATM  unit  each
is located on  the  campus  of  Saint Vincent  College  in  Unity
Township,  the  terminal   of   the Westmoreland  County  Airport
in  Unity  Township  and in  the reception  lobby of  the Latrobe
Area Hospital in Latrobe. A separate freestanding drive-up teller
staffed banking facility is attached  to  our Lincoln Road office
in downtown  Latrobe.  This facility also provides ATM service.

The  corporation's business activities are limited to  holding
the  stock  of  its subsidiary bank and the remaining  discussion
pertains to the activities of that bank.

The  subsidiary bank offers the full range of banking services
normally associated with the general commercial banking business.
Services  include  extending credit, providing deposit  services,
marketing   non-deposit   investments  and   offering   financial
counseling.   The ATM system described earlier is a part  of  the
MAC and Cirrus networks which permits the bank's customers access
to an extensive regional and national network. The bank  also has
implemented  a  comprehensive  electronic  home-banking  system.
This  product known as the Maxcess (at this point, there appears
a service mark) SM  Account,  provides  our  customers  with the 
option  of  paying bills through personal computer, screenphone,
touchtone phone and even rotary  phone. During 1997, the Maxcess
(at this point, there appears a service mark)SM  Check Card was
introduced. The card can be  used by customers  at ATMs and have
funds drawn electronically for purchases from merchants displaying
a Mastercard or MAC symbol.

[FN]
MAXCESS is a service mark of Commercial National Bank of
Westmoreland County

<PAGE>

Competition
-----------
Throughout  the  subsidiary bank's service  area,  substantial
competition  exists  both for deposit  and  loan  products.  The
competitors range from branches of major Cleveland Ohio, Indiana,
Pittsburgh  and Johnstown Pennsylvania  based  banks,  several 
independent  banks headquartered  in   Westmoreland   County,  a  
variety  of thrift institutions  and  a number of credit unions.  
Even though some portions of the thrift industry have experienced
fairly extensive restructuring, the level of competitive activity 
in  our service area remains strong. Competition for certificates
of deposit and money  market  deposits remains vigorous  with the
representatives of  insurance  companies and  securities  brokers
soliciting  customers   in   our  market  area.   In  addition,  
out-of-area institutions including retailers continue to solicit
business for credit cards, residential mortgages and automobile
financing.


Supervision and Regulation
--------------------------
As a result of the establishment of the holding company format,
the  holding company and the subsidiary bank are subject  to  the
supervision  of  the  following regulatory bodies:   The  Federal
Reserve Board, the Office of the Comptroller of the Currency, the
Securities   and   Exchange  Commission,  the   Commonwealth   of
Pennsylvania  Department  of  Banking  and  the  Federal  Deposit
Insurance Corporation.  The nature of the supervision extends  to
such  areas as safety and soundness, truth-in-lending,  truth-in-
savings, rate restrictions, consumer protection, permissible loan
and  securities  activities, merger and acquisition  limitations,
reserve   requirements,   dividend   payments   and   regulations
concerning   activities  by  corporate  officers  and  directors.
Because  the  corporation and the bank confine  their  activities
within  a single county, changes to intra and inter-state banking
regulations  have had little impact inasmuch as  the  competitive
situation described earlier can not be altered significantly  nor
is  the  corporation  likely to take  advantage  of  the  broader
branching  or merger options now available.  The Federal  Reserve
Board  monitors holding company activity while the Office of  the
Comptroller of the Currency is the corporation's primary  banking
regulator.   No  restrictions or actions  are  currently  pending
against the corporation or the bank.

Effects of Governmental Policies
--------------------------------
In addition to the regulatory requirements, the corporation and
its  subsidiary bank are affected by the national economy and the
influence on that economy exerted by governmental bodies  through
monetary and fiscal policies and their efforts to implement  such
policies.    In  particular,  the  impact  of  the  open   market
operations  on  interest  rates,  the  establishment  of  reserve
requirements  and the setting of the discount rate will  continue
to affect business volumes and earnings.  The exact nature or the
full  extent  of  this  impact is almost impossible  to  predict;
however,  management continues to monitor these activities  on  a
regular  basis  and seeks to modify its policies  and  procedures
accordingly.

Management review and evaluation of loan loss experience and loan loss 
potential on outstanding loans occurs on a monthly basis  and  is
considered  in  conjunction with current economic conditions  and
the current requirements of the appropriate regulatory agencies.

As a result of this on-going study, management believes that the
reserve amount shown for December 31, 1997 is adequate to  offset
the   expense   which   may  exist   as   a   result   of   under
collateralization or uncollectibility.

Item 2.  Properties
         ----------
         All of the corporation's banking and support facilities are owned
         and free of liens  and encumbrances with the exception of one (1) 
         banking office and an  adjacent drive-up  facility, both of which
         are leased. All of the properties are used in their entirety for  
         banking  purposes.  In each  case,  the  properties  have  been 
         maintained in good repair, are well suited for their present use
         and  appear  to  be  adequate  for  the  immediate  needs of the
         corporation and the bank. During 1997, existing corporate offices
         expanded onto the third floor  of the former Plaza Hotel property
         which  was  immediately  adjacent  to and  is now part the bank's
         corporate  headquarters. The  first  and  second  floors  of  the 
         building  will  be  finished  at a later  date as the demand for 
         additional space becomes apparent.

Item 3.  Legal Proceedings
         -----------------
         Other  than proceedings which occur in the normal  conduct  of
         business,  there  are no legal proceedings to  which  either  the
         corporation or the subsidiary bank is a party which will have any
         material effect  on  the  financial position of the  corporation 
         and  its subsidiary.

Item 4.   Submission of Matters to a Vote of Security Holders
          ---------------------------------------------------
