Physical Presence Technology Employees Redirecting Resources At C&N, we are taking a proactive approach to these changes by adjusting our delivery model in a three-tiered approach; our physical presence, technology and employees Over the last few years, there has been a drastic decrease in the number of in-branch transactions due to the increase in technology and online banking services Many customers are managing their daily banking activities remotely from their smartphones, tablets and computers As a result, the decision was made to close our Ralston branch and redirect these resources We are also in the midst of relocating our Towanda branch to a new state-of-the-art facility that positions us to better serve our customers Our mergers and acquisitions team has been hard at work evaluating potential markets and partnerships throughout the region In October, we announced a pending acquisition of Monument Bank in Bucks County, PA with two branches and a loan production office We plan to finalize this acquisition in the second quarter of 2019 At the end of January, we also announced an expansion into York, PA with a loan production office and long-term plans to add two new branches in that area 2 MOMENTUM: The Pursuit of Excellence

2018 was an outstanding year at C&N and the theme of this year's Annual Highlights - Momentum - is most appropriate Our efforts over the past several years to strengthen our values-based culture and business model grounded on relationships are producing current performance while we also build future capacity Our efforts have been disciplined and persistent and progress has been steady In 2018, C&N announced its expansion into Bucks County, PA through the pending acquisition of Monument Bank, delivered strong earnings, continued the extraordinary community engagement of the C&N Team, and provided a solid return to shareholders through price appreciation and an increased dividend Importantly, we continued the discipline of investing in our people, technology, and data management to support strategic growth and expansion and to continue our momentum into the future The September announcement of the acquisition of Monument Bank is a significant event for C&N as we step out of our historic market area We have built an exceptionally strong community banking franchise with capacity for growth 2017 Earnings for both J BRADLEY SCOVILL Establishing a presence in Bucks County is an initial step to leverage our strengths in a larger market with a partner that is a strong cultural fit and shares our focus on local communities Monument's market leadership and lending teams will remain in place and begin to utilize the products, services and years were affected by the change in tax rates enacted in late 2017 and by net securities gains/losses, so it is useful to discuss our results on a pre-tax basis after adjusting for both items With these adjustments, 2018 pre-tax income was $24.2 million, a 19.2% increase from other resources provided by C&N to create additional value for customers upon closing of the transaction which is expected to occur in the second quarter We We have built an exceptionally strong community banking franchise with capacity for growth $20.3 million in 2017 Sustained revenue growth was the primary driver as both net interest income and noninterest income grew at a substantially faster pace than are confident this strategic move will create long term value for our shareholders as we drive growth in Bucks County and seek additional opportunities to expand into attractive markets over time While we have been actively pursuing expansion, our focus on deepening relationships to grow the historic franchise has not wavered Our regional market Teams are steadily improving their effectiveness at identifying customer needs and delivering solutions from all business lines And while these markets are not growing rapidly, there is significant opportunity to improve market share, particularly in Lycoming County in Pennsylvania and Steuben and Chemung counties in New York This core franchise has produced excellent results and will continue to provide the foundation for growth in the years ahead Net income totaled $22 million during 2018 or $1.79 per share as compared to $13.4 million or $1.10 per share in noninterest expenses during the year This operating leverage in our core business gained momentum in 2018 Growth in net interest income and expansion of the net interest margin resulted from modest overall loan growth, the strength of C&N's core deposits, and continued improvement in the mix of the balance sheet Loan growth was muted due to lower production levels and several larger commercial loan payoffs, however the mix of new loan business and repricing in the portfolio produced higher yields and revenue Total deposit growth was solid for the year Demand deposits were the primary source of growth which further improved our funding mix and controlled the related costs Credit quality remains stable and solid as measured by our past due and non-performing loans metrics at year- end when compared to December 31, 2017 The provision was $584,000 in 2018 compared to $801,000 in 2017 This decrease was primarily due to a lower level of specific MOMENTUM: The Pursuit of Excellence 5

reserves on commercial loans and more modest loan growth Management maintains a robust process to determine the adequacy of the allowance that incorporates a broad range of factors Generation of core noninterest income is a strength for C&N and is one of the positive outcomes of our focus on developing value-based relationships with Noninterest expenses increased approximately 7% when compared to 2017 Salaries and wages were the primary component of this growth, driven by performance-based salary adjustments, incentive compensation, and additional staff Pensions and employee benefits declined primarily due to lower health care expenses Data processing and telecommunications increases customers Trust and brokerage revenues from our wealth management business continued to grow as we added new business and received the full year benefits of a modest fee increase implemented in mid- 2017 Service charges and fees related to our core deposits, Importantly, we continued the discipline of investing in our people, technology, and data management to support strategic growth and expansion and to continue our momentum into the future resulted from investment in systems and technology and their ongoing costs Professional fees were higher due to acquisition expenses and various other projects, and the mid- year donation of the Towanda Office to a non-profit pushed contributions expense higher for including interchange revenue from debit cards, also increased substantially Net gains from the sale of loans declined as conforming mortgage loan originations as a percentage of total mortgage originations declined, resulting in fewer sales the year Leveraging C&N's capital position and paying off our investments in C&N's capacity for growth have been important elements of our strategic plan for the past several years 6 MOMENTUM: The Pursuit of Excellence

The Monument acquisition is consistent with this strategy and provides some initial leverage along with the potential for substantial future growth Our focus has also been on producing earnings that support a strong dividend and positive stock valuation, positioning our "currency" to support our capacity for growth 2018 earnings were exceptional and dividends per share increased from $1.04 to $1.08, producing a dividend yield of 4.09% based on the December 31, 2018 closing price of $26.43 per share This closing price was a 10.1% increase from the $24.00 closing price a year earlier At its January 2019 meeting, the Board of Directors declared a regular quarterly dividend of $.27 per share, or an annualized rate of $1.08 per share At the same time, the Board declared a special dividend of $.10 per share in recognition of C&N's overall performance in 2018 and the Company's ongoing strength As we look to continue our momentum going forward, the external environment remains positive, on balance National and regional economic growth remain solid while politics and the Federal Reserve continue to influence the broad economy and the banking industry We foreshadowed the possibility of regulatory relief and further Fed rate hikes in the 2017 Annual Review and in 2018, both occurred The Economic Growth, Regulatory Relief, and Consumer Protection Act (the "Act") was signed into law in May 2018, with the goal of easing the burden imposed by the Dodd-Frank legislation passed in 2010 There are provisions in the new Act that may simplify and streamline the activities of smaller banks relating to reporting requirements, regulatory capital standards, certain lending functions, and brokered deposits We expect to benefit from some elements of the Act immediately while others will take time to assess A more substantial and immediate impact was felt as the Fed raised its fed funds target rate four times in 2018 to 2.25% - 2.50% This continued tightening of monetary policy reflected the Fed's ongoing concern regarding inflation as the economy remained strong throughout the year At year-end, however, Chairman Powell stated that the Fed would be patient about further increases and would be driven by economic data moving forward While short term rates increased, longer rates decreased during the year and the yield curve flattened substantially, extending the challenging environment faced by banks to expand the net interest margin While the rate environment has not had a significant impact on business and lending activity, management will devote significant attention to our efforts to generate deposit growth while managing the cost of funds in 2019 During 2018, two of our Directors, R Bruce Haner and Edward H Owlett, III, retired from the Board Having served for 20 years and 24 years respectively, Bruce and Ed have provided C&N with leadership, advice, and counsel throughout their tenures We thank them for their commitment and many contributions to C&N We also welcomed Bobbi Kilmer to the Board Bobbi has been the President & CEO of Claverack Rural Electric Cooperative since 2006 and comes to C&N with extensive business experience and knowledge of our regional markets She is also serving as the Chair of the Mansfield University Council of Trustees, one of her numerous community and professional volunteer activities We look forward to her insight and perspective as she contributes to C&N's future success To continue momentum into 2019, C&N will remain committed to developing our Team and our values-based culture and sustaining performance in our core franchise We are also excited to work through the integration activities with our partners at Monument Bank and pursue the opportunities presented by expanding into new markets We have an engaged and motivated Team that is focused on our mission of Creating Value Through Lifelong Relationships for our customers, communities, and shareholders I remain confident in their ability to be successful and grateful for their commitment to C&N Thank you to all of our shareholders for your confidence and continued support MOMENTUM: The Pursuit of Excellence 7
