Forward Looking Statements
3
This presentation, the prospectus supplement, the prospectus in the registration statement and the documents incorporated by reference therein contain forward-looking 
statements, within the meaning of Section 27A of the Securities Act of 1933, as amended, which we refer to as the Securities Act, and Section 21E of the Securities 
Exchange Act of 1934, as amended, which we refer to as the Exchange Act, with respect to the financial condition, liquidity, results of operations, future performance 
and business of CNB Financial Corporation. These forward-looking statements are intended to be covered by the safe harbor for “forward-looking statements” provided 
by the Private Securities Litigation Reform Act of 1995. Forward-looking statements are those that are not historical facts. These forward-looking statements include 
statements with respect to our beliefs, plans, objectives, goals, expectations, anticipations, estimates and intentions that are subject to significant risks and uncertainties 
and are subject to change based on various factors (some of which are beyond our control).   The words “may,” “could,” “should,” “would,” “believe,” “anticipate,” 
“estimate,” “expect,” “intend,” “plan” and similar expressions are intended to identify forward-looking statements. 
While we believe our plans, objectives, goals, expectations, anticipations, estimates and intentions as reflected in these forward-looking statements are reasonable, we 
can give no assurance that any of them will be achieved.  You should understand that various factors, in addition to those discussed elsewhere in this presentation, the 
prospectus supplement, the prospectus in the registration statement and the documents incorporated by reference in this presentation, the prospectus supplement and 
the prospectus in the registration statement, could affect our future results and could cause results to differ materially from those expressed in these forward-looking 
statements, including:
• changes in general business, industry or economic conditions or competition; 
• changes in any applicable law, rule, regulation, policy, guideline or practice governing or affecting financial holding companies and their subsidiaries or with respect to
   tax or accounting principals or otherwise;
• adverse changes or conditions in capital and financial markets;
• changes in interest rates;
• higher than expected costs or other difficulties related to integration of combined or merged businesses; 
• the inability to realize expected cost savings or achieve other anticipated benefits in connection with business combinations and other acquisitions; 
• changes in the quality or composition of our loan and investment portfolios;
• adequacy of loan loss reserves; 
• increased competition;
• loss of certain key officers;
• continued relationships with major customers; 
• deposit attrition;
• rapidly changing technology;
• unanticipated regulatory or judicial proceedings and liabilities and other costs;  
• changes in the cost of funds, demand for loan products or demand for financial services; and
• other economic, competitive, governmental or technological factors affecting our operations, markets, products, services and prices. 
Because such forward-looking statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such statements. 
The foregoing list of important factors is not exclusive and you are cautioned not to place undue reliance on these factors or any of our forward-looking statements, 
which speak only as of the date of this document or, in the case of documents incorporated by reference, the dates of those documents. We do not undertake to update 
any forward-looking statements, whether written or oral, that may be made from time to time by or on behalf of us except as required by applicable law.

Marcellus Shale Natural Gas
Marcellus Shale Formation
Natural gas development stimulates the economy
Natural gas ancillary businesses
Payments to land owners
Although in early stages, Marcellus gas producers spent $4.5
billion to develop shale gas reserves in 2009, up from $3.2
billion in 2008
Estimated to have created 44,000 jobs state-wide
Employment opportunities could expand to 111,000 jobs by
the end of 2011
Companies plan to increase spending to $8.8 billion for 2010
and over $11 billion for 2011
Projects are likely 2-4 years away from completion and
management believes that these projects could represent an
economic opportunity to western central PA

Tangible common equity to tangible assets is a non-GAAP financial measure calculated using GAAP amounts.  Tangible common
equity
is
calculated
by
excluding
the
balance
of
goodwill
and
other
intangible
assets
from
the
calculation
of
stockholders’
equity. 
Tangible assets is calculated by excluding the balance of goodwill and other intangible assets from the calculation of total assets.  CNB
believes
that
this
non-GAAP
financial
measure
provides
information
to
investors
that
is
useful
in
understanding
our
financial
condition. 
Because not all companies use the same calculation of tangible common equity and tangible assets, this presentation may not be
comparable to other similarly titled measures calculated by other companies.  A reconciliation of this non-GAAP financial measure is
provided below.
