April 2016 Dear Fellow Shareholders: Like most banking companies, the challenge to grow earnings in this historic low interest rate environ- ment continues. Low interest rates hurt us in many ways from the yield on new loan originations to margin compression to the cost of our pension plan (a soft freeze was instituted in 2010). However, many of our revenue-enhancement and cost-reduction initiatives are kicking in, and we saw earnings climb 15.6% in 2015. We will discuss some of these initiatives below. Financial Results Net income for the year was $9.4 million and earnings per share (EPS) were $2.00, up from $8.2 million and $1.74 respectively from the prior year. Tangible book value grew to $23.53, an increase of 3.6% from a year earlier. In 2015, $4.8 million in dividends were declared, continuing our long history of uninterrupted dividend payments. Our return on average assets was 0.60% and our return on average equity was 6.84%. Commercial loans increased $80.7 million, or 13.0%, and con- sumer and mortgage loans de- creased $33.6 million or 6.7% from year earlier levels, the decrease driven by a strategic decision to sell long-term residential mortgages in the secondary market and to exit the very low rate indirect new car loan business. Evidenced by the ratio of non-performing assets to total as- sets, 0.85% at year-end, credit quality remains strong. De- mand deposits grew $55.7 million or 11.7% while total core deposits (demand, NOW, savings and money market) grew $166.0 million or 15.5% from year earlier levels. At December 31, 2015, our balance sheet reflects to- tal assets of $1.6 billion, total loans of $1.2 billion, total deposits of $1.4 billion and total shareholders’ equity of $137.2 million. Our capital ratios exceed the higher mini- mum regulatory capital requirements for banks under the new Basel III rules. The market value of total assets under management or administration in our Wealth Man- agement Group was $1.9 billion at year-end. A Tale of Two Cities (Markets) It is of interest to note that our bank operates in two different geographies, our legacy Southern Tier/Finger Lakes Region and the Albany/Capital Region. Our lega- cy region provides stable, low-cost funding, and the Al- bany region has been the engine for loan growth. Since we entered the Albany market in 2011, we have en- joyed compound average loan growth of 24% per year in that market. Both markets are vitally important to our success and we believe this platform positions us well for continued profitable organic growth. We also believe there are economies of scale in banking and we plan to grow organically and through acquisition. Earnings Improvement A major focus has been to ratio- nalize our brick-and-mortar branch system and to make it more effi- cient. With new technology reduc- ing branch traffic, we have been reducing branch staff. We are also adopting a “hub and spoke” model where branch managers are responsible for more than one office. The implementation of a “Universal Banker” model in some offices is also creating some staffing efficiencies. We are also looking for opportunities to right-size some locations when leases expire. You should recognize that changes in retail banking delivery will be slower for us given the older demographic we serve and the fact that this segment still views the branch as its primary channel. In terms of expense reductions, we expect to realize savings in our health care expense as more and more employees migrate to a high-deductible health plan from the traditional plan. With stabilization of credit quality, we also expect to see a more normalized provi- sioning expense in the future. This past November, we converted our card brand from Visa to MasterCard®. These debit cards were issued with an EMV chip, the global standard Letter to Shareholders Some banks just talk about service; we live it. “ “ R. Bentley D. Dalrymple 1

today, which provides greater protection for our clients against identity theft and fraud. It also shifts the re- sponsibility and cost of data breaches from the bank to the merchant if they are not equipped to accept the new EMV embedded chip card. With this change, we expect to experience a lift in interchange income and lower fraud losses. On another positive note, we believe our net interest mar- gin has stabilized after years of compression. With most of the asset repricing behind us, growth in our balance sheet should translate into improvement in net interest income. The future direction of interest rates, however, is a wild card and a flat or inverted yield curve, or “negative” interest rates, would pose a new set of challenges for the industry and us. Our margin will also benefit from a modest extension of the duration in our investment securities portfolio. Other Accomplishments Over a year ago, we moved into our new Capital Region headquarters in downtown Albany. Located at 132 State Street, our new regional headquarters is steps away from the Capitol Building. It is exciting to be a part of the revitalization of the former Wellington Row site, which includes a new 204- room Renaissance by Marriott and a new Convention Center. We are also in the process of relocating our Clifton Park, New York, office to a more convenient, free-standing building with a two-bay drive-up and ATM a short distance away from our current storefront location. To better serve the small business segment, we over- hauled the way we do business and created a new oper- ating model—we are already seeing success. This change comes in recognition that we cannot commit the same re- sources in making a $50,000 loan that we use in making a $1 million loan. If you are a client of the bank (you should be if you are a shareholder), you probably like the look of our new state- ments. We began outsourcing the generation of statements last July, which cut costs and delivered a better product. Not a day goes by that we don’t look for ways to take advantage of new technology to make us a more effi- cient organization. CanalCare & CapitalCare— Our Competitive Advantage The consumer banking business has become commod- itized and the only sustainable competitive advantage is the quality of our people and the service they provide. Evi- denced by recent client surveys and other metrics, the qual- ity of our service is very good. Some banks just talk about service; we live it. On the commercial side of our business, CanalCare is very much alive. We continue to respond quickly with tailored solutions for each client. This is our value proposition and our success is clear evidence that we are providing value. Management Appointments and Retirements This past July, our board of directors appointed Anders Tomson President and Chief Operating Officer of the bank. In this position, Anders has responsibil- ity for most functional areas of the bank and reports to the CEO. For the immedi- ate future, Anders retains his position as President of our Capital Bank Division. Anders joined our organization in No- vember of 2010 in anticipation of our ac- quisition of Capital Bank in Albany. He assumed his duties as President of the Division in April of 2011 when the merg- er transaction was consummated. Over the past four years, Anders has done an outstanding job leading our Capital Bank team and delivering strong results for our company. Rick Carr and Melinda Sartori, both Executive Vice Pres- idents who led major bank divisions, retired on December 31st. These two long-serving executives, Rick for 18 years Letter to Shareholders A. Tomson 2

Ronald M. Bentley Chief Executive Officer David J. Dalrymple Chairman of the Board Letter to Shareholders and Melinda for 21 years, have made sig- nificant contributions to our success over the years. Both have been key members of my cabinet and I will miss them. A testament to our succession plan- ning at the bank, Lou DiFabio, Executive Vice President, was named to lead our Business Client Services Group and Tom Wirth was promoted to Executive Vice President and head of our Wealth Management Group. Also retiring at year-end were Assistant Vice President Debra Newcomer after 27 years of service and Vice Presi- dent Susan Smith who joined Chemung Canal in connec- tion with the Bank of America branch purchase. Susan’s banking career spanned 43 years. We wish all of them the very best in retirement. Our Board of Directors At our annual meeting in May, two of our directors will retire from the board: Bill Eggers after 14 years of service and Gene Sneeringer Jr. who served on our board the past five years. Bill joined our board in 2002 coming from Corning Inc. where he held the position of General Counsel and Senior Vice Presi- dent. Gene joined the board in connection with the Capi- tal Bank merger in 2011. We are grateful for their many contributions to our success and we will miss them in the boardroom. In March 2016 we welcomed a new member of the Board, Kevin B. Tully, a partner in Teal, Becker & Chiaramonte, CPA’s PC, a regional accounting firm in Albany, NY. Kevin is a Certi- fied Public Accountant and brings a wealth of experience ad- vising small and midsized businesses in all areas of tax and finance accounting. We welcome Kevin and look forward to the knowledge and input he will bring to the Board. Some Closing Thoughts The years following the financial crisis have been a diffi- cult period for community banks. Low interest rates and an increased regulatory and compliance burden have buffet- ed profitability. We are proud to say we have emerged from this period a healthy and vibrant organization. Indeed, we are well-positioned for future success. We are thankful for the continued support of our clients, employees, share- holders and the communities we serve. In Memory of Bill Clark Bill Clark from our Facilities Department passed away on September 6, 2015 after a brief illness, he was 59 years old. A 32-year employee, Bill provided logistical and general maintenance support throughout our company. He was an avid outdoorsman who loved hunting, fishing and playing golf. Bill played an active role in branch relocations, expansions and acquisitions over the last several years, and took great pride in his work. He was proud of the many friendships he developed throughout his CCTC career. He was quick to lend a hand and tell a story. We will miss his smile, his great sense of humor and hearing the creative nicknames he gave his co-workers. We extend our condolences to Bill’s wife Karen, his mother Erma, his children and grandchildren. Rest in peace, Bill. B. Clark 3 L. DiFabio T. Wirth W. Eggers E. Sneeringer
