Amityville

First visited by Huntington settlers in 1653, Amityville was originally known
as Huntington West Neck South. The area was valued as a source of salt hay, which was used to feed livestock. The land was conveyed to the settlers by Chief Wyandanch in 1658.

From the onset, the area was primarily agricultural, with ties to fishing and boating.

Amityville lore notes the name change to Amityville in 1846. Two versions of the incident prevail. In one report, a meeting turned to mayhem when
residents were discussing a better name for the village post office. Discussions got heated, and one participant called for some amity. Another version reports the name Amityville as a suggestion of mill owner Samuel Ireland, after
Amity, his boat. Either way, the friendly bay village, Amityville, was thus named, and then formally incorporated in 1894.

Over
the years, the farming and marine industries dwindled as summer visitors sought out the beaches, breezes, and recreation of the Great South Bay. Located on the beautiful South Shore in the Town of Babylon, Amityville had become a tourist destination
by the early 1900s. Hotels and grand homes proliferated. One of the largest and most famous hotels was Hotel New Point, which boasted three and one-half stories, 60 guest rooms, bathhouses, and a carriage house. Situated on the Great South Bay, it
was a scheduled stagecoach stop on the Pow-ell Livery schedule from the Amityville Railroad Station. Designed by Wilber Ketchum, Narrasketuck sailboats racing on the Great South Bay were a familiar sight. Entertainers, prominent members of society,
writers, and artists all escaped to Amityville from Manhattan. Some of the more well-known residents and visitors included Annie Oakley, Fred Stone, Will Rogers, and Al Capone, to name a few.

But perhaps nothing catapulted Amityville to fame more that the best-selling novel, The Amityville Horror, published in 1977. Based on a true story, the book and subsequent films made Amityville a
household name throughout the United States and beyond.

Today, Amityville is still the friendly village, known for its Victorian
homes, its active downtown, and its inlets and waterfront amenities. While Amityville remains a recreational and cultural destination, it is also known as a business-friendly village, with a close-knit and involved community. It is a
perfect location for the Suffolk County National Banks thirtieth branch, which opened in November 2010, and is located at the entrance to the Village at 400 Merrick Road. The Bank has received a warm welcome from business owners and consumers,
who value the Banks dedication to serving businesses in Amityville as well as its strong community orientation.

Corporate Profile

Suffolk Bancorp does commercial banking through its wholly owned subsidiary, Suffolk County National Bank. Organized in 1890, SCNB is
a full-service, nationally chartered commercial bank. Most of SCNBs revenue comes from net interest income, and the remainder from charges for a variety of services. SCNB has built a good reputation for personal, attentive service, resulting
in a loyal and growing clientele. SCNB operates 30 full-service offices throughout Suffolk County, New York.

The staff at SCNB works hard to
develop and maintain ties to the communities it serves. SCNBs business includes loans to small and medium-sized commercial enterprises, to professionals, and to individual consumers. Suffolk Bancorps main strategic focus is on small
business owners and professionals and those retail customers who need a range of financial services tailored to their individual needs, and who expect the kind of personal service that is possible only through the establishment of relationships that
develop over time. In recent years commercial loans of all types have increased as a percentage of the loan portfolio and have made substantial contributions to SCNBs profitability. SCNBs primary market is Long Island, New York. Long
Island is home to approximately 2.9 million people outside of the limits of New York City and is primarily suburban in nature. Nassau County and the western end of Suffolk County are a center for commerce and are highly developed, supporting a
diversified economy. The economy on eastern Long Island is based on services that support tourism, a large number of second homes, and agriculture. Together, they generate family incomes greater than the national average, providing Suffolk Bancorp
with a steady and growing demand for loans and other services, and a reliable, reasonably priced supply of deposits.

Dear Shareholder:

To put it plainly, the past year was difficult for Suffolk Bancorp. To say otherwise would not be respectful of the facts, which included an increase in non-performing assets, an increase in our provision
for loan losses from year to year, an increase in net charge-offs, the signing of a formal agreement with our primary regulator, a decline in earnings-per-share, and, consequently, a decline in the price of our stock. These have the full attention
of the Board of Directors and management, have been challenging to our employees, and have been disappointing to you, our shareholders. My fellow directors and I take our responsibilities seriously, and to maintain our credibility and your
confidence in the future of Suffolk Bancorp, we have faced these facts squarely. I will discuss what we plan to do about them as I continue through this message.

I do want to emphasize, even in the face of these facts, that we believe 2010 included some real achievements. Return on equity remained in double-digits, at 10.46 percent. Total risk-based capital
increased to 13.22 percent, up from 11.73 percent a year ago. Book-value-per-share was $15.02, up from $14.27 last year. Our net interest margin (fully-taxable equivalent) actually widened a few basis points, to 5.05 percent from 4.99 percent. We
made money. Thus, whatever challenges we face, we can address them from a position of strength.

So, what are those challenges, why do we face
them, and how will we address them?

They fall into two main categories: asset quality and regulatory compliance.

Asset Quality

The key to understanding
how Suffolk Bancorps asset quality changed is to recognize the effect of a prolonged recession followed by an anemic recovery. Fortunately for Long Island, Suffolks primary and almost exclusive market, the local recession was not as deep
as it was nationally. Long Islanders were generally better funded than business people in many other parts of the country. Unfortunately, faced with an extended slump in revenue, the reserves of even good businesses came under strain, and some of
the loans we made to them became less secure, meaning that we had to classify them as such, and make greater provisions for the allowance for loan losses. Some were unable to make timely payments, resulting in their classification as
non-performing, in which case there was an even greater provision. A few defaulted altogether at which time we commenced foreclosure against the collateral, or in the case of unsecured credits, simply wrote them off.

So what have we done to respond to that situation?

First, subsequent to the first quarter of 2010 but as part of that quarters financial results, we made a substantial provision to our allowance for loan losses, increasing our coverage immediately
to 1.80 percent of loans from 1.06 percent at the end of the previous quarter, to account for greater uncertainty about the quality of some of our loans.

Without delay, we went to work to reduce that uncertainty. We made and are still making numerous changes to our credit policy to identify concentrations of risk, analyze the global cash flows of our
customers, reappraise and otherwise evaluate collateral, and improve credit risk management. We hired a new loan administrator and additional underwriting staff. We contracted with a loan workout specialist, and for an independent evaluation of loan
concentrations. We have undertaken expanded training of our lenders in all of these disciplines, and directed them to emphasize work with our customers to resolve problems as quickly and effectively as possible before the development of new
business.

The most significant project was the reappraisal of all commercial real estate securing loans in excess of $1 million which had not
otherwise been conducted during the last twelve months. While cash flow is the primary basis for lending for such properties, collateral is the insurance policy. We and our regulators felt it was important to confirm the value of that
real estate should cash flow be insufficient to pay those loans as agreed. We are pleased to

report that collateral securing loan balances of $366,857,000 was appraised at $758,700,000, resulting in a ratio of loans-to-value (LTV) of 48 percent. We are also pleased to
announce that, subsequent to year-end, of the $7.5 million of foreclosed real estate taken into Other Real Estate Owned (OREO) during the fourth quarter, we have already disposed of $4.7 million, owing to the determined, hard work of our
lending staff. We cannot guarantee that the remainder will be sold so quickly, but the same, intense effort is being made on those properties as well.

Regulatory Compliance

The most honest assessment of how we found ourselves in a formal
agreement with our primary regulator would be that for many years, we had been focused almost solely on profitability and efficiency. In a better economy, this was very much to your benefit as shareholders.

At a certain point, however, those efficiencies may have become too much of a good thing. The best illustration of this might be our headcount (full-time
equivalent (FTE). It peaked at 426 FTEs in 1994 when we had $811 million in assets. Ten years later, in 2004, with assets of $1.3 billion, FTEs totaled 374. At the end of 2010, with $1.6 billion of assets, there were 370
FTEs. Much of our ability to grow without adding staff was properly attributable to changes in technology, methods, and training, all of which improved greatly during the period. An additional part was attributable to inflation, which though
moderate, was also steady throughout. But at a certain point, to continue to grow, Suffolk Bancorps infrastructure must be expanded in order to properly manage risk, internal controls, and administration. That time is now.

On October 25, 2010, we signed a formal agreement with our primary regulator that addressed, among other things, management, staffing, strategic
planning, capital, liquidity, internal audit, a number of issues to do with credit, compliance, information technology, and encompassing them all, risk management. Even after the challenges I enumerated in the first paragraph of this message, our
financial performance is still better than that of our national peer group. But our regulator was concerned that we may have been leveraging our capital and our staff in an environment where the risks were greater than they had been at any time in
recent memory, and it wanted us to demonstrate that we both understand and have addressed those risks to its satisfaction. To that end, the Board and our corporate staff have been devoted to compliance with the agreement, while our line staff tends
to the relationships with our customers that are the foundation of our business. We have analyzed and have made submissions on each of the articles in the agreement, augmented our compliance staff, rewritten and further tightened a score of internal
policies and procedures, and continued to work with our regulator daily to comply fully with the agreement to be able to return to business as usual, as quickly as we can. We are improving our infrastructure so that as the economy
improves, we can grow prudently, effectively, and profitably.

My colleagues on the Board and in management are optimistic about our
prospects, both in relative terms in our ability to continue to outperform others in our industry, and in absolute terms to grow as improvements in the economy permit. The economy is still sluggish, and we continue to work on the formal agreement,
so we make no promises about our performance in the future. Nonetheless, all of us at Suffolk believe in our mission to our shareholders, customers, and the communities we serve. Good Relationships are Good Business. That is our motto. We understand
that we need to earn your trust every day. I hope that this message will take us another step in that direction.

Recent Developments and Current Trends

Suffolk Bancorp is a one-bank holding company engaged in the commercial banking business through
Suffolk County National Bank, a full-service commercial bank headquartered in Riverhead, New York. SCNB is Suffolk Bancorps wholly owned subsidiary. Organized in 1890, Suffolk County National Bank is headquartered on Long Island,
with 30 offices in Suffolk County, New York.

Recent Developments

During 2010, increasing amounts of credit were available to a select group of highly qualified borrowers as banks attempted to generate assets of high quality that would provide at least some spread over
more highly liquid investments such as fed funds, which had been priced at historically low rates of interest, typically well below 1 percent. However, deposits generally continued to increase as individuals and businesses hesitated
either to spend or employ these funds elsewhere. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the Act) was signed into law by President Obama on July 21, 2010, and established the general direction of financial
regulation. Much of the law extended discretion to regulators to promulgate regulations concerning a wide variety of issues. Uncertainty as to what those regulations might be and when they might take effect, amplified that hesitation as businesses
waited for clarity as to how they would affect their operations. Short-term rates remained near zero, and the yield curve remained comparatively steep in comparison with historic averages, with the margins between short- and long-term
rates unusually wide. However, a rally in the bond market continued to lower long term rates more than short, suggesting to observers that the net interest margin of many banks might compress going forward, after having widened during the past
several quarters. Low short-term rates were primarily the result of continuing, low short-term targets set by the Federal Reserve Board for federal funds and discount rates. It was also the result of continuing concern about the possibility of
inflation over the longer term as a result of deficit spending by the federal government, and the development of an offsetting concern late during the previous quarter that the recovery might stall, leading to deflation. Rates of unemployment
remained high by historic standards.

As disclosed previously, the prolonged slump in the economy has strained the resources of some of
Suffolks borrowers. Suffolk is a community bank that relies upon net interest income generated by the relationships it builds with the owners of small and medium-sized businesses, in contrast to certain large banks that profit from the
proprietary trading of securities and derivatives. Suffolks prospects remain tied more to Main Street than to Wall Street. At the start of the recent recession, Suffolks primary market area was wealthier than many other
markets. Owners of small businesses and other customers appeared to have greater financial reserves than similar customers in other regions of the nation, and the development of real estate, both residential and commercial, was more mature and
therefore less speculative. This contributed to a steadier and less dramatic decline than elsewhere; and Suffolks borrowers remained current in their obligations longer. However, as time has passed, the economy appears to have stabilized at
lower levels of output and higher levels of unemployment than before 2008.

At Suffolk, interest income decreased slightly, while net interest
income increased, primarily due to reduced interest expense. The net interest margin increased to 5.05 percent in 2010, up from 4.99 percent during 2009. Net interest income was offset, however, by substantially higher provisions for loan losses,
which increased by 296.4 percent over 2009.

At December 31, 2010, of the $35,183,000 of non-performing loans, $32,637,000 was secured by
collateral valued at approximately $50,542,000, having an average loan-to-value ratio of approximately 65 percent. The unsecured portion of $2,546,000 amounted to 23 basis points of net loans at year end. To determine the adequacy of the allowance
for loan losses Suffolk considered not only the status of non-performing loans on its books, but the performance of Suffolks peers. Although Suffolk continues to work with borrowers to ensure the collection of non-performing credits, some of
these loans were being paid more slowly than originally anticipated. This increased the allowance for loan losses to $21,288,000 at December 31, 2010, up from $12,333,000 at December 31, 2009. The majority of non-performing loans are
commercial and industrial loans, and loans secured by commercial real estate. The allowance is established through a provision for loan losses based on managements evaluation of the risk inherent in the various components of the loan portfolio
and other factors, including Suffolks own historical loan loss experience as well as Suffolks peer bank loss experiences. Suffolk increased its provision for loan loss and its allocated reserve to reflect the deterioration of the overall
economy, credit quality trends in the portfolios of Suffolks peer banks, and regulatory guidance and expectations. See Allowance for Loan Losses.

While non-performing assets as a percent of total assets increased much later at Suffolk than in peer banks, they increased from 173 basis points at December 31, 2009, to 264 basis points at
December 31, 2010. Non-performing loans to total loans amounted to 314 basis points at December 31, 2010 from 253 basis points at December 31, 2009. As noted in the discussion above, most non-performing loans are well collateralized.
However, as they remain non-accruing over a period of time, on the basis of objective and selective criteria, Suffolk may or may not elect to charge these and other loans off prudentially, even when they remain in collection and there is the
reasonable remaining expectation of the recovery of amounts owed and expenses incurred in collection. These charge-offs may or may not mirror

trends, on a trailing basis, in ratios of non-performing assets to total assets and non-performing loans to total loans. The amounts charged-off may be substantial in comparison with
Suffolks past loss history, although they may result in net recoveries at some point in the future if the economy improves and borrowers financial conditions strengthen, although there can be no assurance that this will happen. Further
discussion concerning the determination of the provision for loan losses is found in the following under the caption, Allowance for Loan Losses.

On October 25, 2010, the Bank, following discussion with the Office of the Comptroller of the Currency (OCC), entered into an agreement with the OCC (the Agreement). The
Agreement requires the Bank to take certain actions, including a review of management, the establishment of a three-year strategic plan and capital program, and the establishment of programs related to internal audit, maintaining an adequate
allowance for loan losses, real property appraisal, credit risk management, credit concentrations, Bank Secrecy Act compliance, and information technology.

Management and the Board of Directors are committed to taking all necessary actions to promptly address the requirements of the Agreement, and believe that the Bank has already made measurable progress in
addressing these requirements. In connection with the foregoing, the Bank has retained legal and other resources including the services of a compliance consultant to assist and advise in meeting the requirements of the Agreement.

While subject to the Agreement, Suffolk expects that its and the Banks management and Board of Directors will be required to focus a substantial
amount of time on complying with its terms. There also is no guarantee that the Bank will be able to fully comply with the Agreement. If the Bank fails to comply with the terms of the Agreement, it could be subject to further regulatory enforcement
actions.

Basic Performance and Current Activities

Return on average equity decreased to 10.46 percent in 2010, down from 18.30 percent during 2009, and basic earnings-per-share decreased from $2.35 in 2009 to $1.56 in 2010. Decreases in return on average
equity and basic earnings-per-share are primarily due to increased provision for loan losses, up 296.4 percent from the prior year. Additionally, the return on average equity decreased as average equity increased 16.5 percent from 2009 to 2010. Key
factors included:



| |  |  | Increase in provision for loan losses of $12,670,000.
| | - |  | -----------------------------------------------------



| |  |  | Increase in non-interest expense of $2,299,000, including other real estate owned (OREO) expense of $882,000 and legal, consulting, and
other costs of approximately $500,000 to comply with formal agreement, increased legal fees for collection of loans, forced-placed insurance for properties securing loans, real estate taxes for delinquent borrowers, and increased expense for
advertising.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Increase in provision for loan losses and increase in non-interest expense were offset by a lower tax provision than for 2009.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------

Although Suffolks net interest income after the provision for loan losses decreased, Suffolks net interest
income and core performance improved. Key to maintaining performance was disciplined management of the balance sheet. These steps included:



| |  |  | Maintaining emphasis on both commercial and personal demand deposits, and non-maturity time deposits, as a key part of relationships with customers,
while responding as necessary to demand in Suffolks market for certificates of deposit of all sizes. Suffolk continues its emphasis on the profitability of the whole relationship of its customers with the Bank, seeking when possible to both
make loans to and obtain funding from the best qualified customers.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Managing net loan charge-offs and non-performing loans. During the year ended December 31, 2010, net charge-offs were 71 basis points of average
net loans. Non-performing assets, including loans and OREO, amounted to $42,732,000 or 2.6 percent of total assets. Non-performing loans amounted to $35,183,000 or 3.1 percent of total loans. Lending staffs first efforts continue to be
directed to the management of such credits, and then to developing new business with an emphasis on the most profitable customer relationships.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Managing the investment portfolio in a difficult rate environment and continued purchases of municipal securities, which provide liquidity as well as
higher returns net of taxes, and some protection from falling interest rates.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

It has not been Suffolks policy to
grant loans or to buy investment securities backed by loans which would be characterized as sub-prime.

Suffolks Business

Nearly all of Suffolks business is to provide banking services to its commercial and retail customers in Suffolk County, on Long Island, New York.
Suffolk is a one-bank holding company. Its banking subsidiary, Suffolk County National Bank (the Bank), operates 30 full-service offices in Suffolk County, New York. It offers a full line of domestic, retail, and commercial banking
services, and trust services. The Banks primary lending area includes all of Suffolk County, New York, and a limited number of loans or loan-participations in the adjacent markets of Nassau County and New York City. The Bank makes loans that
are secured by commercial real estate and float with the prime rate and other indices, and that are retained in the Banks portfolio: commercial and industrial loans to small manufacturers, wholesalers, builders, farmers, and retailers,
including dealer financing. The Bank serves as an indirect lender to the customers of a number of automobile dealers. The Bank also makes loans secured by residential mortgages, and both fixed and floating rate second mortgage loans with a variety
of plans for repayment. Real estate construction loans are also offered.

Other investments are made in short-term United States Treasury
debt, high-quality obligations of municipalities in New York and other states, issues of agencies of the United States government, collateralized mortgage obligations, mortgage-backed securities, and stock in the Federal Reserve Bank and the FHLBNY,
each required as a condition of membership.

The Bank finances most of its activities with deposits, including demand, saving, N.O.W., and
money market accounts, as well as term certificates. It also relies on other sources of funds, including inter-bank overnight loans, and sale-repurchase agreements.

General Economic Conditions

Long Island has a population of
approximately 2.9 million people, which has increased about 4 percent since 2000, a growth rate on par with the New York region, but much lower than growth in the United States as a whole. Long Island has a number of important regional
advantages, including public and private schools and universities that are ranked above national averages; an increasingly diversified economy with growing health, information, and business services; as well as hundreds of miles of coastline and
other open spaces that draw tourists from within and beyond the region. However, Long Island also faces a number of challenges as a result of the historical fragmentation of governance among towns, villages, special authorities, and other taxing
districts, as well as growing disparity in incomes.

In 2010, the total private sector gross metropolitan product (GMP) for Long
Island was $125 billion. Consistent with the global economic recession, this is flat from 2009 and down 4.6 percent from 2008, when Long Islands GMP was at its peak of $131 billion. Despite the prolonged economic recession, the Long Island GMP
is still up 10 percent for the decade due to sustained private sector expansion of about 2.5 percent per year from 2001 through 2007. As compared to the rest of the nation, Long Islands recession was deeper and has taken longer to recover.
From 2008 to 2009, the U.S. private sector gross domestic product (GDP) shrank by 3.3 percent. Long Islands GMP contracted at an even higher rate of 4.3 percent. By 2010, the nation had returned to economic growth at a rate of 2.3
percent. Long Islands rate of contraction has slowed of late; in 2010 it remained slightly negative at (0.4) percent. (Source: Long Island Index 2011)

Results of Operations

Net Income

Net income was $15,020,000, a decrease of 33.4 percent from $22,548,000 in 2009, which decreased 8.7 percent from $24,688,000 in 2008. Basic earnings-per-share were $1.56 during 2010, compared to $2.35 in
2009 and $2.58 in 2008. The decrease in net income is primarily due to an increased provision for possible loans losses, up 296.4 percent over 2009.

Net Interest Income

Net interest income during 2010 was
$76,592,000, up 3.0 percent from $74,336,000 in 2009, which was up 12.3 percent from $66,220,000 in 2008. Net interest income is the most significant part of the net income of Suffolk. The net interest rate margin, on a taxable-equivalent basis, was
5.05 percent in 2010, 4.99 percent during 2009, and 4.75 percent in 2008. Average rates of interest on average interest-earning assets decreased to 5.66 percent in 2010, down from 5.80 percent in 2009, and 6.27 percent in 2008. Average rates on
average interest-bearing liabilities decreased to 0.95 percent in 2010, down from 1.24 percent in 2009, and 2.24 percent in 2008. Demand deposits remained a significant source of funds as a percentage of total liabilities.

Interest income on a taxable-equivalent basis includes the additional amount of interest income that would have
been earned if Suffolks investment in nontaxable U.S. Treasury securities and states and municipal obligations had been subject to New York State and federal income taxes yielding the same after-tax income. The rate used for this adjustment
was approximately 34 percent for federal income taxes and 9 percent for New York State income taxes for all periods. For each of the years 2010, 2009, and 2008, $1.00 of nontaxable income from obligations of states and political subdivisions equates
to fully taxable income of $1.52, and $1.00 of nontaxable income from taxable obligations of states and political subdivisions equates to fully taxable income of $1.50. In addition, in 2010, 2009, and 2008, $1.00 of nontaxable income on U.S.
Treasury securities equates to $1.02 of fully taxable income. Various loan fees included in interest income amounted to $1,304,000; $1,594,000; and $1,817,000 in 2010, 2009, and 2008, respectively.

Analysis of Changes in Net Interest Income

The table below presents a summary of changes in interest income, interest expense, and the resulting net interest income on a taxable-equivalent basis
for the periods presented, each as compared with the preceding period. Because of numerous, simultaneous changes in volume and rate during the period, it is not possible to allocate precisely the changes between volumes and rates. In this table
changes not due solely to volume or to rate have been allocated to these categories based on percentage changes in average volume and average rate as they compare to each other: (in thousands)

Interest Income

Interest income decreased to $86,306,000 in 2010, down 0.8 percent from $87,008,000 in 2009, which was down 1.6 percent from $88,457,000 in 2008.

Investment Securities

SCNB purchases investment securities only after a disciplined evaluation to ensure that they are the most appropriate available given the companys objectives. Key factors include:



| |  |  | Liquidity  the ease with which the security can be pledged or sold.
| | - |  | --------------------------------------------------------------------



| |  |  | Credit Quality  the likelihood the security will perform according to its original terms, with timely payments of principal and interest.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Yield  the rate of return on the investment, balanced against the first two.
| | - |  | -----------------------------------------------------------------------------

Investment securities are also selected in consideration of certain key risks to:



| |  |  | Market value  the market value of fixed-rate securities increases when interest rates fall, and decreases when interest rates rise. The longer
the maturity of the security, the greater this effect.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Income risk  how long fixed payments can be assured. The shorter the duration of the portfolio, the greater this risk.
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | Asset liability management  seeks to limit the change in net interest income as a result of changing interest rates. For example, when the
maturities or the intervals between the repricing of investments are longer than those of the liabilities that fund them, net interest income will decline when rates rise because payments from those securities will remain the same while payments to
depositors or other banks from which SCNB has borrowed will increase. This is referred to as asset-sensitive. Conversely, when investments mature or are repriced sooner than their funding, net interest income may decline when interest
rates fall as income declines the same while funding expense remains the same. Asset liability management attempts to manage the duration of the investment portfolio, as well as that of the funding to minimize the risk to net interest income while
maximizing returns.

##### Table of Contents

The company seeks to create a portfolio that is diversified across different classes of assets.
Historically, bonds have returned more than cash, and been less volatile than mortgage-backed securities (MBS). The steady return on bonds can also offset the decline in variable loan yields as interest rates fall. Collateralized
mortgage obligations (CMOs) provide more predictable cash flows because payments are assigned to specific securities (tranches or slices) in the order in which they are received, in contrast to a traditional security
backed by a pool of mortgages in which investors share payments equally pro rata, based on the percentage of the pool they own. Analysis of CMOs requires careful due diligence of the mortgages that serve as the underlying collateral. Suffolk
has never owned mortgage obligations with underlying collateral that could be classified as sub-prime. Tranche structure, final maturity, and credit support also provide improved assurance of repayment. There are CMOs which have
experienced increased delinquencies in the underlying loan portfolio; however, these securities are in senior tranches where delinquencies and foreclosures result in accelerated cash flows received, and not losses. Suf-folk reviews its investments
for impairment regularly, and to date, none have been determined to be other-than-temporarily impaired due to credit.

Average investment in
U.S. government agency securities decreased to $38,525,000 from $79,358,000 in 2009, and $94,801,000 in 2008. Average balances of CMOs increased to $181,463,000 in 2010 from $148,566,000 in 2009, and $145,285,000 in 2008. Average investments
in municipal securities increased to $220,957,000 in 2010, up from $194,089,000 in 2009 and $164,296,000 in 2008. U.S. Treasury, U.S. government agency, collateralized mortgage obligations, and municipal securities provide collateral for various
liabilities to municipal depositors. Securities are Suffolks primary source of liquidity. With regard to securities characterized as available for sale, in general, Suf-folk has the intent and ability to hold them until maturity. The following

Loan Portfolio

Loans, net of unearned discounts but before the allowance for loan losses, totaled $1,120,290,000. Loans secured by commercial real estate amounted to $433,737,000 and comprise 38.7 percent of the
portfolio, the largest single component, up from $375,652,000 in 2009, and $352,502,000 in 2008. Commercial, financial, and agricultural loans followed at $252,334,000, down 2.8 percent from $259,565,000 at the end of 2009. These loans are made to
small local businesses throughout Suffolk County. Commercial loan balances are seasonal, particularly in the Hamptons where retail inventories rise in the spring and decline by autumn. Consumer loans are a declining part of the portfolio. Net of
unearned discounts, they totaled $67,814,000 at the end of 2010, down 15.6 percent from $80,352,000 at year-end 2009. Consumer loans include indirect, dealer-generated automobile loans. Competition among commercial banks and with captive finance
companies of automobile manufacturers has reduced yields and volume. Additionally, rising fuel costs and uncertainties regarding the economy have led to a decline in consumer confidence, affecting automobile sales. Regional financial institutions
have tightened their lending activities as a result of turmoil in the credit markets, offering continuing opportunity for real estate construction, and residential and commercial mortgage lending.

The remaining significant components of the loan portfolio are residential mortgages at $195,993,000, down 8.6 percent from $214,501,000; home equity
loans at $84,696,000, up 2.3 percent from $82,808,000; and construction loans at $84,589,000, down 36.6 percent from $133,431,000. Construction loans decreased primarily because as the projects securing these loans have been completed they are moved
into permanent financing as they begin to generate their intended cash flows. These loans have been underwritten on the basis of reasonable ratios of loan-to-value, evaluations of projected cash flows, guarantees for permanent financing in place
prior to granting the interim credit, and the ability of the borrower to repay the loan from sources other than the sale of the secured property. Other loans consist of overdraft advances nearly all of which have been repaid subsequent to year-end.

Non-Performing Loans

Generally, recognition of interest income is discontinued when reasonable doubt exists as to whether interest can be collected. Ordinarily, loans no
longer accrue interest when 90 days past due. When a loan stops accruing interest, all interest accrued in the current year, but not collected, is reversed against interest income in the current year. Loans start accruing interest again when they
become current as to principal and interest, and when, in the opinion of management, they can be collected in full.

Total non-performing loans and restructured loans past due as of December 31, 2010 amounted to $35,676,000. Of that
amount, $32,637,000 was secured by collateral valued at approximately $50,542,000, having a cumulative loan-to-value of approximately 65 percent.

Interest on loans that are no longer accruing interest would have amounted to about $1,510,000 for 2010 under the contractual terms of those loans. Suffolk records the payment of interest on such loans as
a reduction of principal. Interest income recognized on restructured and non-accrual loans was $1,188,000 for 2010, and immaterial for the years 2009 and 2008. Suffolk has a formal procedure for internal credit review to more precisely identify risk
and exposure in the loan portfolio.

Impaired loans are segregated and reviewed separately. Impaired loans secured by collateral are reviewed
based on their collateral and the estimated time required to recover Suffolks investment in the loan as well as the cost of doing so, and the estimate of the recovery anticipated. Reserves are allocated to impaired loans based on this review.
The allocated reserve is an estimation of losses specific to individual impaired loans. Allocated reserves are established based on an analysis of the most probable sources of repayment and liquidation of collateral. Reserves allocated to impaired
loans were $3.3 million and $3.0 million as of December 31, 2010 and December 31, 2009, respectively. While every non-performing loan is evaluated individually, not every loan requires an allocated reserve. Allocated reserves fluctuate
based on changes in the underlying loans, anticipated sources of repayment, and charge-offs.

Impairment was measured on approximately $26,495,000 or 75 percent of our impaired loans as of December 31, 2010 with
the assistance of a third-party appraisal. As of December 31, 2009, impairment was measured on approximately $6,009,000 or 18 percent of our impaired loans with the assistance of a third-party appraisal. Collateral-dependent loans are evaluated
for impairment when a loan becomes 90 days past due or another impairment indicator is identified. At the time a loan is evaluated for impairment, an appraisal is ordered from an independent third-party licensed appraiser for loans in excess of
$250,000. Typically, it takes approximately 30-90 days to receive and review the appraisal on a commercial real estate mortgage. To date, the Company has not experienced any significant delays between ordering appraisals and recognizing charge-offs.
While waiting for an updated appraisal, we continue to contact the borrower to arrange a payment plan and monitor for any payment. Since the majority of the collateral securing impaired loans are within our local market, an officer of the Bank may
drive by to make an initial assessment of the propertys condition.

Once the updated appraisal is received, if the fair value less
estimated costs to sell is less than the carrying amount of the loan, we record a charge-off for the difference. We do not increase the value of any of our loans based upon an appraisal amount greater than our carrying amount. All
collateral-dependent impaired loans have had a third-party appraisal during the past 12 months, except for one loan whose most recent appraisal dated 2009 was discounted by 10 percent. Additionally, the Bank has obtained updated appraisals during
2010 for most of the commercial real estate portfolio including non-impaired loans, and commercial real estate and construction loans totaling $516,068,000 at December 31, 2010. Of this balance, updated appraisals were obtained for
$366,857,000, representing 71 percent of the portfolio. The total combined collateral value of the $366,857,000 loans recently appraised totaled $758,700,000. This represents a total combined loan-to-value ratio of 48 percent for the loans most
recently appraised. As of December 31, 2010, our impaired loans inclusive of previously recognized charge-off amounts totaled $37,565,000. Subsequent to charging off the difference, collateral-dependent loans are deemed to be non-performing
impaired loans. As of December 31, 2010, there is one loan totaling $6,546,000 that has been restructured for which a partial charge-off has been recognized totaling $1,400,000. The terms of the restructured loan include a reduced interest
rate. The loan is currently classified as non-accrual. Additional funds have been advanced for this loan, and a valuation reserve has been established for these advances.

At December 31, 2010, impaired loans totaling $24,398,000 have no associated valuation allowance. For these loans, an evaluation for impairment was completed with no measurement of impairment. The
measurement is based upon the appraisal methodology described above for collateral-dependent loans. For non-collateral-dependent loans, measurement is based on the present value of future cash flows. As measuring impairment is an estimate which
requires judgment, future results of operations may be negatively affected by outcomes different from those estimated.

Suffolk evaluates
classified and criticized loans that are not impaired by categorizing loans by type of risk and applying reserves based on loan type and corresponding risk. Suffolk also records reserves on Suffolks non-criticized and non-classified loan
balances. This represents a general allowance for homogeneous loan pools where the loans are not individually evaluated for impairment, though rated according to loan product type and risk rating.

This amount is determined by applying loss factors to pools of loans within the portfolio having similar risk characteristics.

In addition, external factors are considered for areas of concern that cannot be fully quantified in the allocation based on historical net charge-off
ratios. External factors include:



| |  |  | Economic outlook
| | - |  | ----------------



| |  |  | Trends in delinquency and problem loans
| | - |  | ---------------------------------------



| |  |  | Changes in loan volume and nature of terms of loans
| | - |  | ---------------------------------------------------



| |  |  | Effects of changes in lending policy
| | - |  | ------------------------------------



| |  |  | Experience, ability, and depth of lending management and staff
| | - |  | --------------------------------------------------------------



| |  |  | Concentrations of credit
| | - |  | ------------------------



| |  |  | Board and Loan Review oversight
| | - |  | -------------------------------



| |  |  | Changes in value of underlying collateral
| | - |  | -----------------------------------------



| |  |  | Competition, regulation, and other external factors
| | - |  | ---------------------------------------------------

For performing loans, an estimate of adequacy is made by applying external factors specific to the portfolio to the period-end balances. Suffolk used a higher percentage factor for criticized and
classified loans, given their potential for greater loss. Consideration is also given to the type and collateral of the loans with particular attention paid to commercial real estate construction loans, due to the inherent risk of this type of loan.
Allocated and general reserves are available for any identified loss.

Delinquent, non-performing, and classified loans have trended upward.
These are primary factors in the determination of the allowance.

##### Table of Contents

At December 31, 2010, non-performing loans and past due restructured loans totaled $35,676,000 as
compared with $29,372,000 at December 31, 2009. When compared to total loans, non-performing loans rose to 3.14 percent at December 31, 2010, up from 2.53 percent at December 31, 2009. Commercial mortgages and commercial real estate
construction loans were primarily responsible for the increase. Non-performing loans include all non-accrual loans and loans 90 days or more delinquent.

For non-performing loans, cash receipts are applied entirely against principal until the loan has been collected in full,
after which time, any additional cash receipts are recognized as interest income. When, in managements judgment, the borrowers ability to make required interest and principal payments resumes and collectability is no longer in doubt, the
loan is returned to accrual status. When interest accruals are suspended, accrued interest income is reversed and charged to earnings. During the years ended December 31, 2010 and 2009, interest income totaling $1,239,000 and $957,000,
respectively, was recognized on impaired loans. Cash basis interest income recognized on those loans during that period was immaterial.

Restructured loans totaled $20,856,000 at December 31, 2010 and $11,674,000 at December 31, 2009. The increase in restructured loans is the
result of the prolonged economic slowdown in the region. Included in non-performing loans are restructured loans of $8,488,000 at December 31, 2010, that are no longer accruing interest. Subsequent to restructure, there has been $671,000 in
advances funded on non-performing restructured loans outstanding as of December 31, 2010.

As of December 31, 2010 and
December 31, 2009, we consider the non-performing restructured loans totaling $8.5 million and $10.3 million, respectively, to be impaired loans. The loans that have been restructured have been modified as to interest rate, due dates, or
extension of the maturity date. Restructured loans are considered to be non-accrual loans, if at the time of restructuring the loan was deemed non-accrual. Once a sufficient amount of time has passed, generally six months, if the restructured loan
has performed under the modified terms, the loan is returned to accrual status. In addition to the passage of time, we also consider the collateral value and the ability of the borrower to continue to make payments in accordance with the modified
terms. During the year ended December 31, 2010, there were no restructured loans returned to accrual status. During the year ended December 31, 2010, there were restructured loans charged-off totaling $65,000. During the year ended
December 31, 2010, a restructured loan totaling $7,275,000 had $1,400,000 of the balance charged-off during the quarter ended June 30, 2010 as a result of a new appraisal indicating the fair value less estimated costs to sell was less than
the carrying amount of the loan.

As of both December 31, 2010 and December 31, 2009, we have not performed any commercial real
estate (CRE) or other type of loan workouts whereby an existing loan was restructured into multiple new loans.

During the year ended
December 31, 2010, Suffolk acquired three properties through foreclosure (OREO.) The carrying value of OREO, which is recorded at fair value, less estimated selling costs, was $7,549,000 at December 31, 2010. Subsequent to year
end, $4,742,000 of OREO was sold for a net gain of $448,000.

As of December 31, 2010, classified loans amounted to 6.85 percent of total
loans, as compared with 3.48 percent at December 31, 2009. The increase is attributable to the prolonged national and regional economic slowdown.

Real estate construction loans amount to $84,589,000 as of December 31, 2010. Non-performing real estate construction loans total $13,120,000, which is 15.5 percent of the real estate construction
portfolio.

Real estate construction loans as a percentage of the loan portfolio have decreased since December 31, 2009; however,
the non-performing balance of real estate construction loans as a percentage of all non-performing loans has increased from 36.68 percent at December 31, 2009 to 37.29 percent at December 31, 2010. Although the allowance has increased during
that same period, it has not increased to the same extent as the increase in non-performing loans. This is a result of the measurement of impairment, and because of the collateral value of the real estate construction portfolio, reserves were not
required to reflect the same level of increase as the non-performing loans themselves.

Suffolk recorded a provision for loan losses for the
year ended December 31, 2010 of $16,945,000, an increase of $12,670,000 as compared to the year ended December 31, 2009. The total provision recorded for the year ended December 31, 2009 was $4,275,000. During the year ended
December 31, 2010, Suffolk recorded $8,041,000 in net loan charge-offs compared to $993,000 for the year ended December 31, 2009. The increase in the provision for loan losses and net charge-offs in 2010 is primarily the result of the prolonged
decline in the regional economy, which has resulted in customers who are not able or willing to remain current in their obligations. Suffolk believes that the allowance for loan losses of $21,288,000, or 1.90 percent of total loans at
December 31, 2010, is adequate based on its review of overall credit quality indicators and ongoing loan monitoring processes. As required by the Agreement with the OCC, Suffolk is in the process of reviewing its allowance for loans losses,
which may result in an increased provision to the allowance.

Summary of Loan Losses and Allowance for Loan Losses

The allowance for loan losses is determined by continuous analysis of the loan portfolio. That analysis includes changes in the size and
composition of the portfolio, historical loan losses, industry-wide losses, current and anticipated economic trends, and details about individual loans. It also includes estimates of the actual value of collateral and other possible sources of
repayment. There can be no assurance that the allowance is, in fact, adequate. When a loan, in full or in part, is deemed uncollectible, it is charged against the allowance. This happens when it is well past due and the borrower has not shown the
ability or intent to make the loan current, or the borrower does not have enough assets to pay the debt, or the value of the collateral is less than the balance of the loan and not likely to improve soon. Residential real estate and consumer loans
are analyzed as a group and not individually because of the large number of loans, small balances, and historically low losses. In the future, the provision for loan losses may change as a percentage of total loans. The percentage of net charge-offs
to average net loans during 2010 was 0.71 percent, compared to 0.09 percent in 2009, and 0.06 percent during 2008. The ratio of the allowance for loan losses to loans, net of discounts, was 1.90 percent at the end of 2010, up from 1.06 percent in
2009 and 0.83 percent in 2008. A summary of transactions follows: (in thousands)

Suffolk considers the determination of the allowance for loan losses to involve a higher degree of judgment and complexity than its other significant accounting policies. Suffolk maintains an allowance
for loan losses at a level that management believes will be adequate to absorb probable losses on existing loans that may become uncollectible based on evaluations of collectability. Suffolks underwriting standards generally require a
loan-to-value ratio of 75 percent or less, and when applicable, a debt coverage ratio of at least 120 percent, at the time a loan is originated. Suffolk has not been directly affected by the increase in defaults of sub-prime mortgages as Suffolk
does not originate, or hold in portfolio, sub-prime mortgages. The allowance for loan loss analysis includes changes in the size and composition of the portfolio, Suffolks own historical loan losses, current and anticipated economic trends,
and details about individual loans. It also includes estimates of the actual value of collateral, other possible sources of repayment and estimates that are susceptible to significant changes due to changes in appraisal values of collateral,
national and regional economic conditions, and other factors. The analysis also considers the loan loss history of Suffolks peers with similar characteristics. In assessing the adequacy of the allowance, Suffolk reviews its loan portfolio by
separate categories which have similar risk and collateral characteristics; e.g. commercial loans, commercial real estate, construction loans, residential mortgages, home equity loans, and consumer loans. Management conducts a monthly analysis of
the loan portfolio which evaluates any loan designated as having a high risk profile including but not limited to, loans classified as Substandard or Doubtful as defined by regulation, loans criticized internally or
designated as Special Mention, delinquencies, expirations, overdrafts, loans to customers having experienced recent operating losses and loans identified by management as impaired. The analysis is performed to determine the amount of the
allowance which would be adequate to absorb probable losses contained in the loan portfolio. The analytical process is regularly reviewed and adjustments may be made based on the assessments of internal and external influences on credit quality. As
required by the Agreement with the OCC, Suffolk is in the process of reviewing its allowance for loan losses policy which may result in an increase to the allowance. During 2010, Suffolk experienced an increase in classified and criticized loans as
a result of the deterioration of the economy and resulting failure of businesses, devaluation of assets, and the effect on customers ability to service debt. This was further noted in Suffolks review of the report of the Banks
third-party loan reviewer.

There can be no assurance that the allowance is, in fact, adequate. When a loan, in full or in part, is deemed
uncollectible, it is charged against the allowance. This happens when it is past due and the borrower has not shown the ability or intent to make the loan current, or the borrower does not have enough assets to pay the debt, or the value of the
collateral is less than the balance of the loan and not likely to improve soon. In the future, the allowance for loan losses may change as a percentage of total loans. To the extent actual performance differs from managements estimates,
additional provisions for loan losses may be required that would reduce or may substantially reduce earnings in future periods, and no assurances can be given that Suffolk will not sustain loan losses, in any particular period, that are sizable in
relation to the allowance for loan losses.

##### Table of Contents

Net charge-offs for the year ended December 31, 2010 were $8.0 million compared to $993,000 of net
charge-offs for the year ended De-cember 31, 2009. The increased charge-offs were realized in all of our loan categories. This increase in charge-offs reflects the deterioration of economic conditions and resulting failure of businesses, devaluation
of assets, and negative impact on customers ability to service debt. For impaired collateral-dependent loans, which include commercial real estate mortgages and real estate construction loans, charge-offs were the result of new appraisals
indicating a collateral deficiency after considering costs to sell.

Interest Expense

Interest expense in 2010 was $9,714,000, down from $12,672,000 the year before, which was down from $22,237,000 during 2008. Interest expense decreased in 2010 due to decreased rates paid for all
interest-bearing liabilities. Most interest was paid for the deposits of individuals, businesses, and various governments and their agencies. The cost of funds of average interest-bearing deposits decreased from 1.09 percent during 2009 to 0.87
percent during 2010. Borrowings include federal funds purchased (short-term lending by other banks), securities sold under agreements to repurchase, and FHLBNY borrowings. The Federal Reserve Bank discount window was available though not used during
2010. Borrowings averaged $93,169,000 during 2010, $131,986,000 during 2009, and $206,878,000 during 2008.

Deposits

Average interest-bearing deposits increased to $926,058,000 in 2010, up 3.8 percent from $892,366,000 in
2009. Saving, N.O.W., and money market deposits increased during 2010, averaging $601,953,000, up 6.8 percent from 2009 when they averaged $563,513,000. Average time certificates of less than $100,000 totaled $104,282,000, down 15.8 percent from
$123,905,000 in 2009. Average time certificates of $100,000 or more totaled $219,823,000, up 7.3 percent from $204,948,000 during 2009. During 2008, the Bank entered into an agreement with Promontory Interfinancial Network, LLC, for the purpose of
issuing certificates of deposit through their CDARS® program. As of December 31, 2010, the Bank had issued
$12,368,000 in brokered certificates of deposit, up from $5,046,000 as of December 31, 2009. A portion of the Banks demand deposits are reclassified as saving accounts on a daily basis. The sole purpose of the reclassification is to
reduce the non-interest-bearing reserve balances that the Bank is required to maintain with the Federal Reserve Bank, and thereby increase funds available for investment. Although these balances are classified as saving accounts for regulatory
purposes, they are included in demand deposits in the accompanying consolidated statements of condition.

Borrowings

Suffolk uses both short-term and long-term funding when it is advantageous to do so in comparison with the alternatives. This includes borrowings from the Federal Home Loan Bank, lines of credit for
federal funds with correspondent banks, and repurchase agreements.

Other Income

Other income decreased to $10,913,000 during 2010, down 1.8 percent from $11,118,000 during 2009, which was down 24.1 percent from $14,643,000 during 2008. Service charges on deposit accounts decreased
10.0 percent from 2009 to 2010, and by 3.9 percent from 2008 to 2009. Other service charges were up 7.8 percent and 8.5 percent for the same periods, respectively. Fiduciary fees in 2010 totaled $976,000, down 3.4 percent from 2009 when they
amounted to $1,010,000, which was down 30.8 percent from 2008, at $1,460,000. Other operating income decreased by 18.5 percent, mainly attributable to a decrease in the sale of residential mortgage loans to the secondary market. During the fourth
quarter of 2010, $11,109,000 of municipal securities were sold at a net gain of $363,000. Net security gains for 2010 totaled $375,000. There were no sales of securities in 2009. Net security gains totaled $3,741,000 in 2008, $3,737,000 of which
pertained to the proceeds from the sale of shares issued by Visa, Inc. in connection with its initial public offering. Suffolks subsidiary, SCNB, was a member of the former Visa, Inc. payments organization and was issued shares when Visa, Inc.
was organized. Approximately 39 percent of those shares were redeemed in connection with the initial public offering. The remaining shares are restricted because of unsettled litigation pending against Visa, Inc. Accordingly, Suffolk has recorded
these shares at zero in the accompanying statement of condition.

Other Expense

During 2010, other expense was $51,100,000, up 4.7 percent from 2009 when it was $48,801,000, which was up 14.3 percent from $42,701,000 in 2008.
Salaries and employee benefits increased 0.9 percent, and net occupancy expense grew by 6.1 percent. Equipment expense decreased 10.5 percent. The remainder of other operating expense increased 10.2 percent primarily due to increased professional
fees associated with collections of delinquent loans, increased costs associated with information technology and appraisal fees. Suffolk anticipates substantial additional expenses associated with meeting the requirements of the Agreement both
nonrecurring over the next one to two years and permanent increases thereafter.

In December 2009, SCNB confirmed that an unauthorized
intruder accessed certain customers log-in information via the computer server hosting SCNBs Online Banking system. As a result, 8,378 Online Banking customers were affected, amounting to less than 10 percent of SCNBs total
customers. To date, SCNB has found no evidence of any unauthorized access to Online Banking accounts, nor received any reports of unusual activity or reports of financial loss to its customers. Expenses associated with investigation and remediation
regarding this event totaled $205,000.

Deposits meeting certain regulatory criteria as to size held at SCNB are insured by the Federal
Deposit Insurance Corporation (FDIC). The FDIC maintains the Deposit Insurance Fund (DIF) by assessing depository institutions an insurance premium. The amount each institution is assessed is based upon statutory factors that
include the balance of insured deposits as well as the degree of risk the institution poses to the insurance fund. SCNB has participated in the FDICs Transaction Account Guarantee Program. Under the program,

which was extended from June 30, 2010 until December 31, 2010, all non-interest-bearing transaction accounts were fully guaranteed by the FDIC for the entire amount in the account.
Coverage under the Transaction Account Guarantee Program was in addition to and separate from the $250,000 coverage available under the FDICs general deposit insurance rules. Due to the passage of the Dodd-Frank Act, all deposits held in
non-interest-bearing transaction accounts will be fully insured, regardless of the amount in the account. Interest-bearing transaction and non-transaction accounts will be subject to coverage up to $250,000 per depositor, per insured bank, for each
account ownership category. Effective for the FDIC insurance assessment payable September 30, 2011, which covers the second quarter of 2011, the FDIC assessment will be based on the Banks total average assets less Tier 1 capital, instead
of deposits. The assessment on average assets will be computed at lower rates, which may result in lower deposit premiums beginning in the second quarter of 2011. FDIC assessments increased to $2,751,000 or 1.3 percent from 2009 when it was
$2,717,000, which was up 459.1 percent from $486,000 in 2008. In prior years, the FDIC granted a one-time initial assessment credit to recognize an institutions past contributions to the DIF. For SCNB, this credit totaled $970,000. Up to
ninety (90) percent of the credit was applied to the annual assessment with the remainder carried forward to the next year. In 2008, approximately $340,000 of the remaining one-time initial assessment credit offset DIF premiums of $777,000. In
June 2009, SCNB paid a special assessment charged by the FDIC in the amount of $770,000. On November 12, 2009, the FDIC adopted a final rule imposing a 13-quarter prepayment of FDIC premiums. Suffolks prepayment amount totaled $7,158,000
and was paid in December 2009. This was an estimated prepayment for the fourth quarter of 2009 through the fourth quarter of 2012. The prepayment amount is used to offset FDIC premiums and began in March 2010.

The provision for income taxes decreased from $9,830,000, for an effective income tax rate of 30.4 percent in 2009, to $4,440,000, for an effective
income tax rate of 22.8 percent in 2010, primarily as a result of increased investments in municipal securities. Bank tax provisions of New York State Article 32 allow banking corporations to exclude from income 60 percent of the dividends it has
received from subsidiaries such as a real estate investment trust (REIT). On various occasions over the course of a number of years, the tax commissioner of New York State has proposed the elimination of this provision, raising the
question for New York State banking corporations as to whether this exclusion would remain in effect. Going forward, the Company may not realize the benefits of the exclusion from income of 60 percent of the dividends received from the REIT,
resulting in a higher effective state income tax rate.

Asset/Liability Management &
Liquidity

The Asset/Liability Management Committee (ALCO) reviews Suffolks financial performance and compares it to the
asset/liability management policy. The committee includes four outside directors, executive management, the senior lenders, the comptroller, and the head of risk management. It uses computer simulations to quantify interest rate risk and to project
liquidity. The simulations also help the committee to develop contingent strategies to increase net interest income. The committee always assesses the impact of any change in strategy on Suffolks ability to make loans and repay deposits. Only
strategies and policies that meet regulatory guidelines and that are appropriate under the economic and competitive circumstances are considered by the committee. Suffolk has not used forward contracts or interest rate swaps to manage interest rate
risk.

Suffolk and its subsidiary manage liquidity to ensure that it has funds available, at a reasonable cost, to disburse funds as it
becomes necessary, both in the ordinary course of business, and under extraordinary circumstances. These disbursements are made primarily to: depositors making withdrawals from their accounts; other banks when repaying borrowed funds; borrowers from
the bank when funding loans to which the bank had previously made commitments; purchase investments; respond to unanticipated declines in deposits; take advantage of unanticipated opportunities to lend or invest which may help Suffolk to grow; and
fund operations.

At the parent, Suffolk Bancorp, sources of liquidity included cash and cash equivalents of $2.1 million as of
December 31, 2010, and dividends from the Bank. Cash available for distribution of dividends to shareholders of Suffolk is derived primarily from dividends paid by the Bank to Suffolk. Regulatory restrictions limit the amount of dividends that
may be paid by the Bank (see Capital Resources). Dividends from the Bank to Suffolk at December 31, 2010, were limited to $44.7 million, which represented the Banks net income for 2010 as well as its retained earnings for the previous two
years, less dividends paid. Prior approval from regulators is required if the total of all dividends declared by the Bank in any calendar year exceeds this amount. In addition, under the Agreement, the Bank is required to establish a dividend policy
that will permit the declaration of a dividend only when the Bank is in compliance with its capital program and with the prior written determination of no supervisory objection by the OCC and the Federal Reserve Bank of New York. In the event that
Suffolk expands its current operations, in addition to dividends from the Bank, it will need to rely on its own earnings, additional capital raised, and other borrowings to meet its need for liquidity.

The Banks most liquid assets are cash and cash equivalents, securities available for sale, and securities held to maturity due within one year. The
amounts of these assets are dependent upon the Banks operating, financing, lending, and investing activities during any given period. Other sources of liquidity include principal repayments and maturities of loans and investment securities,
lines of credit with other financial institutions including the Federal Home Loan Bank, growth in core deposits, and sources of wholesale funding such as brokered certificates of deposit and eligibility for lines at the Federal Reserve Bank.
Scheduled loan amortization, maturing securities, and short-term investments are relatively predictable sources of funds, whereas deposit flows and prepayments of loans and mortgage-backed securities are influenced by general interest rates,
economic conditions, and competition, and may vary accordingly. The Bank adjusts its liquidity to fund such things as seasonal deposit outflows and loans, and to pursue asset and liability management objectives using a marginal cost of funds
approach, seeking to find the lowest cost of funding possible for each additional dollar. The Bank relies primarily on its deposits, obtained

through 30 full-service branches that serve its market area, as well as local municipal deposits. The Banks primary service area is Suffolk County, New York, where it holds approximately
4.08 percent of deposits in that market.

During 2010, the Banks core deposits increased, in demand, saving, N.O.W., and money market
accounts, and in other time deposits. Time deposits of $100,000 or more decreased. The Bank borrows from the FHLBNY as advance rates are generally lower than local rates for other time deposits offered by competitors. The Banks Asset/Liability
and Funds Management Policy allows for wholesale borrowings of up to 25 percent of total assets. On December 31, 2010, the Bank had access to total lines of credit in the amount of $26 million which provide for short-term credit for liquidity.
Of this total, $15 million was available on an unsecured basis. As of December 31, 2010, none of these lines had been drawn upon. The Bank is a member of the FHLBNY and may borrow using as collateral unencumbered investment securities and
residential and commercial mortgages owned by the Bank. As of December 31, 2010, the Bank had pledged collateral giving it the capacity to borrow approximately $240.2 million from FHLBNY. As of December 31, 2010, the amount of overnight
borrowings under these lines was zero. The Bank had $40.0 million in term borrowings from the FHLBNY. There were no securities sold under agreements to repurchase from an unaffiliated primary broker as of December 31, 2010. As of
December 31, 2010, the Bank had $12.4 million in brokered deposits.

Interest Rate
Sensitivity

Interest rate sensitivity is determined by the date when each asset and liability in Suffolks portfolio can
be re-priced. Sensitivity increases when interest-earning assets and interest-bearing liabilities cannot be re-priced at the same time. While this analysis presents the volume of assets and liabilities re-pricing in each period of time, it does not
consider how quickly various assets and liabilities might actually be re-priced in response to changes in interest rates. Management reviews its interest rate sensitivity regularly and adjusts its asset/ liability management strategy accordingly.
Because the interest rates of assets and liabilities vary according to their maturity, management may selectively mismatch the re-pricing of assets and liabilities to take advantage of temporary or projected differences between short-and long-term
interest rates.

At December 31, 2010, interest-bearing liabilities with maturities of less than one year
exceed interest-earning assets of similar maturity. This cumulative gap might result in decreased net interest income if interest rates increase or remain stable during the next 12 months. If interest rates decline, net interest income might
increase. However, interest-earning assets with maturities of greater than one year exceed interest-bearing liabilities of similar maturity. This cumulative gap might result in increased net interest income if interest rates increase beyond 12
months. If interest rates decline or remain stable, net interest income might decrease.

Interest
Rate Risk

Interest rate risk is the sensitivity of earnings to changes in interest rates. As interest rates change, interest income and
expense also change, thereby changing net interest income (NII). NII is the primary component of Suffolks earnings. ALCO uses a detailed and dynamic model to quantify the effect of sustained changes in interest rates on NII. While
ALCO routinely monitors simulated NII sensitivity two years into the future, it uses other tools to monitor longer term interest rate risk.

The model measures the effect in the future of changing interest rates on both interest income and expense for all assets and liabilities, as well as for
derivative financial instruments that do not appear on the balance sheet. The results are compared to ALCO policy limits that specify a maximum effect on NII one year in the future, assuming no growth in assets or liabilities, or a 200 basis point
(bp) change in interest rates upward and 100 bp downward. The downward scenario was computed at 100 bp because of historically low interest rates as of the date of computation.

Following is Suffolks NII sensitivity as of December 31, 2010. Suffolks Board has approved a policy limit of 12.5 percent.

##### Table of Contents

These estimates should not be interpreted as Suffolks forecast, and should not be considered as
indicative of managements expectations for operating results. They are hypothetical estimates that are based on many assumptions including: the nature and time of changes in interest rates, the shape of the yield curve (variations
in interest rates for financial instruments of varying maturity at a given moment in time), prepayments on loans and securities, deposit outflows, pricing on loans and deposits, and the reinvestment of cash flows from assets and liabilities, among
other things. While these assumptions are based on managements best estimate of current economic conditions, Suffolk cannot give any assurance that they will actually predict results, nor can they anticipate how the behavior of customers and
competitors may change in the future.

Factors that may affect actual results include: prepayment and refinancing of loans other than as
assumed, interest rate change caps and floors, repricing intervals on adjustable rate instruments, changes in debt service on adjustable rate loans, and early withdrawal of deposits. Actual results may also be affected by actions ALCO takes in
response to changes in interest rates, actual or anticipated.

When appropriate, ALCO may use off-balance-sheet instruments such as interest
rate floors, caps, and swaps to hedge its position with regard to interest rate risk. The Board of Directors has approved a hedging policy statement that governs the use of such instruments. As of December 31, 2010, there were no derivative
financial instruments outstanding.

Market Risk

Market risk is the risk that a financial instrument will lose value as the result of adverse changes in market prices, interest rates, foreign currency exchange rates, commodity prices, or the prices of
equity securities. Suffolks primary exposure to market risk is to changing interest rates. Suffolk originates and invests in interest-earning assets and solicits interest-bearing deposit accounts. Suffolks operations are subject to
market risk resulting from fluctuations in interest rates to the extent that there is a difference between the amounts of interest-earning assets and interest-bearing liabilities that are prepaid, withdrawn, mature, or re-priced in any given period
of time. Suffolks earnings or the net value of its portfolio (the present value of expected cash flows from liabilities) will change when interest rates change. The principal objective of Suffolks asset/liability management program is to
maximize net interest income while keeping risks acceptable. These risks include both the effect of changes in interest rates, and risks to liquidity. The program also provides guidance to management in funding Suffolks investment in loans and
securities. Suffolks exposure to interest-rate risk has not changed substantially since December 31, 2009.

Monitoring and managing
this risk is an important part of Suffolks asset/liability management process. It is governed by policies established by its Board of Directors. These policies are reviewed and approved annually. The Board delegates responsibility for
asset/liability management to ALCO. ALCO then develops guidelines and strategies to implement the policy.

Amounts listed as purchase obligations include agreements to purchase services for Suffolks core banking system.

Suffolk has not used, and has no intention to use, any significant off-balance-sheet financing arrangements for liquidity purposes. Its
primary financial instruments with off-balance-sheet risk are limited to loan servicing for others and obligations to fund loans to customers pursuant to existing commitments.

Capital Resources

Primary capital, including stockholders
equity, not including the net unrealized gain (loss) on securities available for sale, net of tax, the comprehensive gain (loss) on the unfunded projected benefit obligation of the pension plan, and the allowance for loan losses, amounted to
$169,101,000 at year-end 2010, compared to $151,211,000 at year-end 2009 and $132,882,000 at year-end 2008.

The Board has adopted a policy whereby management will maximize both return on average equity and earnings-per-share, and
therefore shareholder value, while maintaining the regulatory standard of well capitalized. That standard is currently 10 percent Total Risk-Based Capital, 6 percent Tier 1 Capital, and 5 percent Leverage Capital. However, increases in
these ratios are currently under public discussion, and are expected to be implemented in the foreseeable future. Accordingly, capital will be allowed to increase to accommodate the standards now anticipated, as well as what an internal analysis
indicates is necessary to allow Suffolk to operate with acceptable risk. The Bank is subject to individual minimum capital ratios established by the OCC for the Bank requiring the Bank to maintain a Tier 1 Capital ratio of at least 8.00 percent of
adjusted total assets, to maintain a Tier 1 Capital ratio of at least 10.50 percent of risk-weighted assets, and to maintain a Total Risk Based Capital ratio at least equal to 12.00 percent of risk-weighted assets. When capital exceeds that standard
meaningfully over what is expected to be required to maintain that standard during the current quarter, shares may be repurchased as they become available at prices that remain accretive to earnings-per-share in transactions under SEC rule 10-b 18
and in private purchases. When capital expected to be required during the current quarter does not exceed the standard, repurchases will not be made. Further, the dividend reinvestment program will automatically follow the same standard, purchasing
shares in the market when Suffolk is in the market to repurchase shares, and issuing from the reserve when it is not. There were no repurchases during 2010.

Suffolk measures how effectively it uses capital by two widely accepted performance ratios: return on average assets and return on average equity. The return in 2010 on average assets was 0.88 percent and
on average common equity was 10.46 percent, compared to 2009 returns of 1.36 percent and 18.30 percent, respectively.

All dividends must
conform to applicable statutory requirements. Suffolk Bancorps ability to pay dividends depends on Suffolk County National Banks ability to pay dividends. Under 12 USC 56-9, a national bank may not pay a dividend on its common stock if
the dividend would exceed net undivided profits then on hand. Further, under 12 USC 60, a national bank must obtain prior approval from the Office of the Comptroller of the Currency to pay dividends on either common or preferred stock that would
exceed the banks net profits for the current year combined with retained net profits (net profits minus dividends paid during that period) of the prior two years. The amount the Bank currently has available to pay dividends is approximately
$44,689,000. The ability of the Bank to pay dividends to

the Company is subject to certain regulatory restrictions. Generally, dividends declared in a given year by a national bank are limited to its net profit, as defined by regulatory agencies, for
that year, combined with its retained net income for the preceding two years, less any required transfer to surplus or to fund for the retirement of any preferred stock of which the Bank has none as of December 31, 2010. A national bank also
may not pay dividends in an amount greater than its undivided profits, and a national bank may not declare any dividends if such declaration would leave the bank inadequately capitalized. In addition, under the Agreement the Bank is required to
establish a dividend policy that will permit the declaration of a dividend only when the Bank is in compliance with its capital program and with the prior written determination of no supervisory objection by the OCC. Therefore, the ability of the
Bank to declare dividends will depend on its future net income and capital requirements and the prior approval of the OCC and Federal Reserve Bank of New York.

During the fourth quarter of 2008, the United States Treasury Department announced the Capital Purchase Program (CPP) of the Troubled Asset Relief Program (TARP). Under the
program, banks were provided the opportunity to obtain additional capital in the form of senior preferred stock bearing an interest rate of 5 percent for five years and 9 percent thereafter and not callable for three years except in consideration of
the issuance of other Tier 1 capital, along with certain warrants to purchase common stock. Suffolk analyzed it carefully and at length, and in light of satisfactory current capital and net income, neither applied for nor accepted funds from the
program.

Risk-Based Capital and Leverage Guidelines

The Federal Reserve Banks risk-based capital guidelines call for bank holding companies to require minimum ratios of capital to risk-weighted
assets, which include certain off-balance-sheet activities, such as standby letters of credit. The guidelines define capital as being core, or Tier 1 capital, which includes common stockholders equity; a limited amount
of perpetual preferred stock; minority interest in unconsolidated subsidiaries, less goodwill; or supplementary or Tier 2 capital, which includes subordinated debt, redeemable preferred stock, and a limited amount of the
allowance for loan losses. All bank holding companies must meet a minimum ratio of total qualifying capital to risk-weighted assets of 8.00 percent, of which at least 4.00 percent should be in the form of Tier 1 capital. Suffolks ratios of
core capital and total qualifying capital (core capital plus Tier 2 capital) to risk-weighted assets were 11.96 percent and 13.22 percent, respectively. The Bank is also subject to individual minimum capital ratios established by the OCC requiring
the Bank to maintain a Tier 1 capital ratio of at least equal to 8.00 percent of adjusted total assets, to maintain a Tier 1 capital ratio at least equal to 10.50 percent of risk-weighted assets, and to maintain a total risk based capital ratio at
least equal to 12.00 percent of risk-weighted assets. At December 31, 2010, the Bank met all three capital ratios as our Tier 1 capital ratio was 8.64 percent of adjusted total assets, our Tier 1 capital ratio was 11.78 percent of risk-weighted
assets, and our Total Risk Based capital ratio was 13.03 percent of risk-weighted assets.

Discussion of New Accounting Pronouncements

In January 2010, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2010-06, which amends the authoritative accounting guidance under
ASC Topic 820 Fair Value Measurements and Disclosures. The update requires the following additional disclosures. 1) Separately disclose the amounts of significant transfers in and out of Level 1 and Level 2 fair value measurements and
describe the reasons for the transfers. 2) Information about purchases, sales, issuances and settlements need to be disclosed separately in the reconciliation for fair value measurements using Level 3. The update provides for amendments to existing
disclosures as follows. 1) Fair value measurement disclosures are to be made for each class of assets and liabilities. 2) Disclosures about valuation techniques and inputs used to measure fair value for both recurring and nonrecurring fair value
measurements. The update also includes conforming amendments to guidance on employers disclosures about post-retirement benefit plan assets. The update is effective for interim and annual reporting periods beginning after December 15,
2009, except for the disclosures about purchases, sales, issuances and settlements in the roll-forward of activity in Level 3 fair value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010, and for
interim periods within those fiscal years. Suffolk has evaluated the provisions of ASU No. 2010-06 and determined there is no material effect on its disclosures, results of operations or financial condition.

In February 2010, the FASB issued ASU No. 2010-09, which amends the authoritative accounting guidance under ASC Topic 855 Subsequent
Events. The update provides that a Securities and Exchange Commission (SEC) filer is required to evaluate subsequent events through the date financial statements are issued. However, an SEC filer is not required to disclose the
date through which subsequent events have been evaluated. The update was effective as of the date of issuance. Adoption of this update did not have a material effect on Suffolks disclosures, results of operations or financial condition.

In July 2010, the FASB issued ASU No. 2010-20 which amends the authoritative accounting guidance under ASC Topic 310,
Receivables. The update amends existing disclosures about an entitys financing receivables on a disaggregated basis to require: 1) a roll-forward schedule of the allowance for credit losses from the beginning of the reporting
period to the end of the reporting period on a portfolio segment basis, with the ending balance further disaggregated on the basis of impairment method; 2) for each disaggregated ending balance in item 1) above, the related recorded investment in
financing receivables; 3) the non-accrual status of financing receivables by class of financing receivables; and 4) impaired financing receivables by class of financing receivables. In addition, the amendments require an entity to provide the
following additional disclosures about its financing receivables: 1) credit quality indicators of financing receivables at the end of the reporting period by class of financing receivables; 2) the aging of past due financing receivables at the end
of the reporting period by class of financing receivables; 3) the nature and extent of troubled debt restructurings that occurred during the period by class of

financing receivables and their effect on the allowance for credit losses; 4) the nature and extent of financing receivables modified as troubled debt restructurings within the previous 12 months
that defaulted during the reporting period by class of financing receivables and their effect on the allowance for credit losses; and 5) significant purchases and sales of financing receivables during the reporting period disag-gregated by portfolio
segment. The disclosures as of the end of a reporting period are effective for interim and annual reporting periods ending on or after December 15, 2010. The disclosures about activity that occurs during a reporting period are effective for
interim and annual reporting periods beginning after December 15, 2010. Suffolk does not expect the provisions of this update to have a material effect on its results of operations or financial condition.

In January 2011, the FASB issued ASU No. 2011-01, which temporarily delays the effective date of the required disclosures about troubled debt
restructurings contained in ASU No. 2010-20. The delay is intended to allow the FASB additional time to deliberate what constitutes a troubled debt restructuring. All other amendments contained in ASU No. 2010-20 are effective as issued.
Adoption of this update did not have a material effect on the Companys results of operations or financial condition.

Critical Accounting Policies, Judgments, and Estimates

The accounting and reporting policies of Suffolk conform to generally accepted
accounting principles in the United States of America (GAAP) and general practices in the financial services industry. The preparation of financial statements in conformity with these accounting principles requires management to make
estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results in the future could differ from those estimates.

Suffolk considers that the determination of the allowance for loan losses involves a higher degree of judgment and complexity than its other significant accounting policies. The allowance for loan losses
is calculated to maintain a reserve believed by management to be sufficient to absorb estimated credit losses. Managements determination of the adequacy of the allowance is based on periodic evaluations of the loan portfolio and other relevant
factors. This evaluation is inherently subjective as it requires material estimates, including, among others, the expected probability of default; the amount of loss in the event of default; the expected usage of loan commitments; the amounts and
timing of cash flows expected in the future from impaired loans and mortgages; and an additional factor for potential loan losses based on historical experience. Management also considers economic conditions, uncertainties in estimating losses, and
inherent risks in the loan portfolio. All of these factors may change significantly in the future. To the extent that actual results differ from managements estimates, additional provisions for loan losses may be required that could reduce
earnings in future periods.

Suffolk recognizes deferred-tax assets and liabilities. Deferred income taxes occur when income taxes are
allocated through time. Some items are temporary, resulting from differences in the timing of a transaction under generally accepted accounting principles, and for the computation of income tax. Examples would include the future tax effects of
temporary differences for such items as deferred compensation and the provision for loan losses. Estimates of deferred tax assets are based upon evidence available to management that future realization is more likely than not. If management
determines that Suffolk may be unable to realize all or part of net deferred tax assets in the future, a direct charge to income tax expense may be required to reduce the recorded value of the net deferred tax asset to the amount that management
expects to realize.

Suffolk evaluates unrealized losses on securities to determine if any reduction in the fair value is other than
temporary. This amount will continue to be dependent on market conditions, the occurrence of certain events or changes in circumstances of the issuer of the security, and the Companys intent and ability to hold the impaired investment at the
time the valuation is made. If management determines that an impairment in the investments value is other than temporary, earnings would be charged.

Business Risks and Uncertainties

This annual report contains
some statements that look to the future. These may include remarks about Suffolk Bancorp, the banking industry, and the economy in general, expectations of the business environment in which Suffolk operates, projections of future performance, and
potential future credit experience. These forward-looking statements are based upon current management expectations, and may, therefore, involve risks and uncertainties that cannot be predicted or quantified and are beyond Suffolks control and
are subject to a variety of uncertainties that could cause future results to vary materially from Suffolks historical performance, or from current expectations. Factors affecting Suffolk Bancorp include particularly, but are not limited to:
changes in interest rates; increases or decreases in retail and commercial economic activity in Suffolks market area; variations in the ability and propensity of consumers and businesses to borrow, repay, or deposit money, or to use other
banking and financial services; results of regulatory examinations; any failure by us to comply with our written agreement with the OCC or the individual minimum capital ratios for the Bank established by the OCC; the cost of compliance with the
Agreement; and the potential that net loan charge-offs are higher than expected. Further, it could take Suffolk longer than anticipated to implement its strategic plans to increase revenue and manage non-interest expense, or it may not be possible
to implement those plans at all. Finally, regulation or accounting standards may require Suffolk to change its practices in ways that materially change the results of operations.

Managements Report on Internal Control over Financial
Reporting

The management of Suffolk Bancorp is responsible for establishing and maintaining adequate internal control over financial
reporting. Suffolk Bancorps internal control system was designed to provide reasonable assurance to the companys management and Board of Directors regarding the preparation and fair presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be
effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Suffolk Bancorp management
assessed the effectiveness of the companys internal control over financial reporting as of December 31, 2010. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO) in Internal Control  Integrated Framework. Based on our assessment and those criteria we have determined that, as of December 31, 2010, the companys internal control over financial reporting is effective.

Suffolk Bancorps independent registered public accounting firm has issued its report on our assessment of the companys internal
control over financial reporting. This report appears on page 56.

Notes to Consolidated Financial Statements

Note 1  Summary of Significant Accounting Policies

The accounting and reporting policies of Suffolk Bancorp (Suffolk) and its subsidiary conform to accounting principles generally accepted in the United States of America (U.S. GAAP) and general practices
within the banking industry. The following footnotes describe the most significant of these policies.

In preparing the consolidated financial
statements, management is required to make estimates and assumptions that affect the reported assets and liabilities as of the date of the consolidated statements of condition. The same is true of revenues and expenses reported for the period.
Actual results could differ significantly from those estimates.

The Financial Accounting Standards Boards (FASB) Accounting
Standards Codification (ASC) became effective for financial statements issued for interim and annual periods ending after September 15, 2009. The ASC or codification became FASBs officially recognized source of
authoritative U.S. GAAP applicable to all public and non-public non-governmental entities, superseding existing FASB, American Institute of Certified Public Accountants (AICPA), Emerging Issues Task Force (EITF) and related
literature. Rules and interpretive releases of the SEC under the authority of federal securities laws are also sources of authoritative GAAP for SEC registrants. All other accounting literature is considered non-authoritative.

(A) Consolidation  The consolidated financial statements include the accounts of Suffolk and its wholly owned subsidiary, Suffolk County
National Bank (the Bank). In 1998, the Bank formed a Real Estate Investment Trust named Suffolk Greenway, Inc. In 2004, the Bank formed an insurance agency named SCNB Financial Services, Inc. All inter-company transactions and balances
have been eliminated in consolidation.

(B) Investment Securities  Suffolk reports debt securities and mortgage-backed securities
in one of the following categories: (i) held to maturity (management has the intent and ability to hold to maturity), which are to be reported at amortized cost; (ii) trading (held for current resale), which are to
be reported at fair value, with unrealized gains and losses included in earnings; and (iii) available for sale (all other debt securities and mortgage-backed securities), which are to be reported at fair value, with unrealized gains
and losses excluded from earnings and reported as a separate component of stockholders equity. Accordingly, Suffolk classified all of its holdings of debt securities and mortgage-backed securities as either held to maturity or
available for sale. At the time a security is purchased, a determination is made as to the appropriate classification.

Premiums
and discounts on debt and mortgage-backed securities are amortized as expense and accreted as income over the estimated life of the respective security using a method that approximates the level-yield method. Gains and losses on the sales of
investment securities are recognized upon realization, using the specific identification method and shown separately in the consolidated statements of income.

Suffolk evaluates unrealized losses on securities to determine if any reduction in the fair value is other than temporary. This amount will continue to be dependent on market conditions, the occurrence of
certain events or changes in circumstances of the issuer of the security, and the Companys intent and ability to hold the impaired investment at the time the valuation is made. If management determines that an impairment in the
investments value is other than temporary, earnings would be charged. Gains and losses on securities are identified using the specific identification method.

(C) Loans and Loan Interest Income Recognition Loans are stated at the principal amount outstanding. Interest on loans not made on a discounted basis is credited to income, based upon the
principal amount outstanding during the period. Unearned discounts on installment loans are credited to income using methods that result in a level yield. Recognition of interest income is discontinued when reasonable doubt exists as to whether
interest due can be collected. Loans generally no longer accrue interest when 90 days past due. When a loan is placed on non-accrual status, all interest previously accrued in the current year, but not collected, is reversed against current-year
interest income. Loans start accruing interest again when they become current as to principal and interest, and when, in the opinion of management, the loans can be collected in full.

(D) Allowance for Loan Losses  The allowance for loan losses is determined by continuous analysis of the loan portfolio. That analysis includes changes in the size and composition of the
portfolio, Suffolks own historical loan losses, current and anticipated economic trends, and details about individual loans. It also includes estimates of the actual value of collateral, other possible sources of repayment and estimates that
are susceptible to significant changes due to changes in appraisal values of collateral, national and regional economic conditions and other factors. Loans in the commercial, commercial real estate, and construction portfolio segments are evaluated
individually for impairment. The loans in the remaining categories consist of loans with smaller balances, which are evaluated as a homogeneous pool. In assessing the adequacy of the allowance, Suffolk reviews its loan portfolio by separate
categories which have similar risk and collateral characteristics; e.g. commercial loans, commercial real estate, construction loans, residential mortgages, home equity loans, and consumer loans. Management conducts a monthly analysis of the loan
portfolio which evaluates any loan designated as having a high risk profile including, but not limited to, loans classified as Substandard or Doubtful as defined by regulation, loans criticized internally or designated as
Special Mention, delinquencies, expirations, overdrafts, loans to customers having experienced recent operating losses and loans identified by management as impaired. The analysis is performed to determine the amount of the allowance
which would be adequate to absorb probable losses contained in the loan portfolio. The analytical process is regularly reviewed and adjustments may be made based on the assessments of internal and external influences on credit quality. Regulatory
examiners may require the Bank to add to the allowance based upon their judgment of information available to them at the time of their examination.

In accordance with FASB ASC 310, Receivables, an allowance is maintained for impaired loans to reflect the difference, if any, between the principal balance of the loan and the present value

of projected cash flows, observable fair value, or collateral value. An impaired loan is defined as a loan for which it is probable that the lender will not collect all amounts due under the
contractual terms of the loan.

Impaired loans which have been identified individually are segregated and reviewed separately. Impaired loans
secured by collateral are reviewed based on their collateral and the estimated time required to recover Suffolks investment in the loan as well as the cost of doing so, and the estimate of the recovery. Reserves are allocated to impaired loans
based on this review. The allocated reserve is an estimation of losses specific to individual impaired loans. Allocated reserves are established based on an analysis of the most probable sources of repayment and liquidation of collateral. Reserves
allocated to impaired loans were $3.3 million and $3.0 million as of December 31, 2010 and December 31, 2009, respectively. While every non-performing loan is evaluated individually, not every loan requires an allocated reserve. Allocated
reserves fluctuate based on changes in the underlying loans, anticipated sources of repayment, and charge-offs.

Suffolk evaluates classified
and criticized loans that are not individually identified as impaired by categorizing loans by type of risk and applying reserves based on loan type and corresponding risk. Suffolk also records reserves on Suffolks non-criticized and
non-classified loan balances. This represents a general allowance for homogeneous loan pools where the loans are not individually evaluated for impairment, though rated according to loan product type and risk rating. This amount is determined by
applying loss factors to pools of loans within the portfolio having similar risk characteristics. In addition, external factors are considered for areas of concern that cannot be fully quantified in the allocation based on the historical net
charge-off ratios.

Transfers of financial assets for which the Bank has surrendered control of the financial assets are accounted for as
sales to the extent that consideration other than beneficial interests in the transferred assets is received in exchange. Retained interests in a sale or securitization of financial assets are measured at the date of transfer by allocating the
previous carrying amount between the assets transferred and based on their relative estimated fair values. The fair values of retained servicing rights and any other retained interests are determined based on the present value of expected future
cash flows associated with those interests and by reference to market prices for similar assets. There were no transfers of financial assets to related or affiliated parties. At December 31, 2010 and 2009, the Banks servicing loan
portfolio approximated $137,256,000 and $132,768,000, respectively, which are not included in the accompanying consolidated statements of condition. The carrying value which approximates the estimated fair value of mortgage servicing rights was
$1,596,000 and $1,444,000 as of December 31, 2010 and 2009, respectively.

(E) Premises and Equipment  Premises and
equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is calculated by the declining-balance or straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized using the
straight-line method over the term of the lease or the estimated life of the asset, whichever is shorter.

The Bank periodically evaluates
impairment of long-lived assets to be held and used or to be disposed of by sale. There was no impairment of long-lived assets as of December 31, 2010 and 2009, respectively.

(F) Other Real Estate Owned  Property acquired through foreclosure (other real estate owned or OREO), is stated at fair value less selling costs. Losses arising at the time of the
acquisition of property are charged against the allowance for loan losses. Any additional write-downs to the carrying value of these assets that may be required, as well as the cost of maintaining and operating these foreclosed properties, are
charged to expense. Additional write-downs are recorded in a valuation reserve account that is maintained asset by asset. The carrying value of OREO at December 31, 2010, was $7,549,000.

(G) Goodwill and Other Intangible Assets Through December 31, 2001, goodwill was amortized on a straight-line basis over a period of ten years. On January 1, 2002, the Bank ceased
amortizing goodwill and, instead, tests goodwill for impairment annually on December 31st or when there is a circumstance that would indicate the need to evaluate between annual tests. No such circumstances occurred in 2010. Based on these
tests, there was no impairment of goodwill as of December 31, 2010 and 2009.

(H) Allowance for Contingent Liabilities  The
balance of the allowance for contingent liabilities is determined by managements estimate of the amount of financial risk in outstanding loan commitments and contingent liabilities such as performance and financial letters of credit. The
allowance for contingent liabilities was $368,000 and $419,000 as of December 31, 2010 and 2009, respectively.

Suffolk has financial and
performance letters of credit. Financial letters of credit require the Bank to make payment if the customers financial condition deteriorates, as defined in the agreements. Performance letters of credit require the Bank to make payments if the
customer fails to perform certain non-financial contractual obligations. The maximum potential un-discounted amount of the future payments of these letters of credit as of December 31, 2010 is $24,430,000 and they expire as follows: (in
thousands)



|                    |  |   |        | 
|------------------- |  | - | ------ | 
|2011                |  | $ | 23,832 | 
|2012                |  |   | 516    | 
|2013                |  |   |       | 
|2014 and thereafter |  |   | 82     | 
|                    |  |   |        | 
|                    |  | $ | 24,430 | 
|                    |  |   |        | 

Amounts due under these letters of credit would be reduced by any proceeds that Suffolk would be able to obtain in
liquidating the collateral for the loans, which varies depending on the customer. The valuation of the allowance for contingent liabilities includes a provision of $37,000 for losses based on the letters of credit outstanding on December 31,
2010.

(I) Income Taxes  Suffolk uses an asset and liability approach to accounting for income taxes. The asset and liability
approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred tax assets are recognized
if it is

more likely than not that a future benefit will be realized. It is managements position that no valuation allowance is necessary against any of Suffolks deferred tax assets.

Suffolk accounts for income taxes in accordance with FASB ASC 740, Income Taxes, which prescribes the recognition and measurement
criteria related to tax positions taken or expected to be taken in a tax return.

(J) Summary of Retirement Benefits Accounting 
Suf-folks retirement plan is noncontributory and covers substantially all eligible employees. The plan conforms to the provisions of the Employee Retirement Income Security Act of 1974, as amended, and the Pension Protection Act of 2006, which
requires certain funding rules for defined benefit plans. Suffolks policy is to accrue for all pension costs and to fund the maximum amount allowable for tax purposes. Actuarial gains and losses that arise from changes in assumptions
concerning future events are amortized over a period that reflects the long-term nature of pension expense used in estimating pension costs.

Suffolk accounts for its retirement plan in accordance with FASB ASC 715, Compensation  Retirement Benefits and FASB ASC 960,
Plan Accounting  Defined Benefit Pension Plans, which require an employer that is a business entity and sponsors one or more single-employer defined benefit plans to recognize the funded status of a benefit plan in its statement of
financial position; recognize as a component of other comprehensive income, net of tax, the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic benefit cost; measure
defined benefit plan assets and obligation as of the date of fiscal year-end statement of financial position (with limited exceptions); and disclose in the notes to financial statements additional information about certain effects of net periodic
benefit cost for the next fiscal year that arise from delayed recognition of the gains or losses, prior service costs or credits, and transition asset and obligation. Plan assets and benefit obligations shall be measured as of the date of its
statement of financial position and in determining the amount of net periodic benefit cost. The codification also requires an employer to use the same date for the measurement of plan assets as for the statement of condition, and provides for either
of two methods to make the transition. Suffolk has chosen to re-measure the obligations of the plan as of the beginning of fiscal year 2008. Under this method, 2008 net periodic pension expense was determined using the market value of plan assets
and liabilities as of January 1, 2008. Accordingly, Suffolk recorded a decrease to prepaid pension cost of $1,297,000, a debit adjustment to opening retained earnings in the amount of $118,000, and a debit adjustment to accumulated other
comprehensive loss in the amount of $1,140,000.

Suffolk accrues for post-retirement benefits other than pensions by accruing the cost of
providing those benefits to an employee during the years that the employee serves. The remeasurement of the post-retirement plan resulted in a credit to the 2008 opening retained earnings in the amount of $157,000.

(K) Cash and Cash Equivalents  For purposes of the consolidated statement of cash flows, cash and due from banks, and federal funds sold are
considered to be cash equivalents. Generally, federal funds are sold for one-day periods.

(L) Stock-Based Compensation  At
December 31, 2010, the Bank had one stock-based employee compensation plan, which is more fully described in Note 8. Stock-based compensation for all share-based payments to employees, including grants of employee stock options, are recognized
in the financial statements based on their fair values.

During 2010, 2009, and 2008, $5,000, $83,000, and $108,000 of compensation expense,
net of a tax benefit of $3,000, $57,000, and $74,000, respectively, was recorded for stock-based compensation. As of December 31, 2010, there was no unrecognized compensation cost, net of estimated forfeitures, related to non-vested options
under the stock-based employee compensation plan.

(M) Treasury Stock  The balance of treasury stock is computed at par value.
The excess cost over par is subtracted from undivided profits.

(N) Earnings-per-share  Basic earnings-per-share are computed by
dividing net income by the number of weighted-average shares outstanding during the period. Diluted earnings-per-share reflect the dilution that would occur if stock options were exercised in return for common stock that would then share in
Suffolks earnings. It is computed by dividing net income by the sum of the weighted-average number of common shares outstanding and the weighted-average number of stock options exercisable during the period. Suffolk has no other securities
that could be converted into common stock, nor any contracts that would result in the issuance of common stock.

(O) Comprehensive
Income  Comprehensive income includes net income and all other changes in equity during a period except those resulting from investments by owners and distributions to owners. Other comprehensive income includes revenues, expenses, gains,
and losses that under generally accepted accounting principles are included in comprehensive income but excluded from net income. Comprehensive income and accumulated other comprehensive income are reported net of related income taxes. Accumulated
other comprehensive income for the Bank consists of unrealized holding gains or losses on securities available for sale, and gains or losses on the unfunded projected benefit obligation of the pension plan.

The unrealized gain on investment securities at December 31, 2010 is mainly attributable an increase of $2,908,000 in
the market value of collateralized mortgage obligations, offset by decreases of $704,000 in the market value of state and political subdivisions, $127,000 in the market value of U.S. Treasury Securities, and $178,000 in the market value of U.S.
Government agency debt. Also included in accumulated other comprehensive income at December 31, 2010, is the reclassification of gain on sale of securities recognized of $223,000, net of taxes.

(P) Segment Reporting FASB ASC 28, Segment Reporting, requires that public companies report certain information about operating
segments. It also requires that public companies report certain information about their products and services, the geographic areas in which they operate, and their major customers. Suffolk is a regional bank, which offers a wide array of products
and services to its customers. Pursuant to its banking strategy, emphasis is placed on building relationships with its customers, as opposed to building specific lines of business. As a result, at December 31, 2010 and 2009, Suffolk is not
organized around discernible lines of business and prefers to work as an integrated unit to customize solutions for its customers, with business line emphasis and product offerings changing over time as needs and demands change. Thus, all necessary
requirements have been met by Suffolk as of De-cember 31, 2010.

(Q) Fair Value Measurements Fair value measurement is
determined based on the assumptions that market participants would use in pricing the asset or liability in an exchange. The definition of fair value includes the exchange price, which is the price in an orderly transaction between market
participants to sell an asset or transfer a liability in the principal market for the asset or liability. Market participant assumptions include assumptions about risk, the risk inherent in a particular valuation technique used to measure fair
value, and/or the risk inherent in the inputs to the valuation technique, as well as the effect of credit risk on the fair value of liabilities.

##### Table of Contents

In accordance with FASB ASC 820, Fair Value Measurements and Disclosures, Suffolk uses three
levels of the fair value inputs to measure assets, as described below.

Basis of Fair Value Measurement:

Level 1Unadjusted, quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets
or liabilities;

Level 2Quoted prices in markets that are not active, or inputs that use pricing models or matrix
pricing;

Level 3Prices or valuation techniques that require inputs that are both significant to the fair value
measurement and unobservable (i.e., supported by little or no market activity).

There were no transfers between levels of fair value
measurement during 2010 and 2009.

(R) Reclassification of Prior Year Consolidated Financial Statements Certain
reclassifications have been made to the prior years consolidated financial statements that conform with the current years presentation. Such reclassifications had no impact on net income.

Included in realized gains on securities as of December 31, 2008, is $3,737,000 of proceeds received in connection with
shares redeemed as part of the Visa, Inc. initial public offering. Suffolks subsidiary, Suffolk County National Bank, was a member of the former Visa, Inc. payments organization and was issued shares when Visa, Inc. was organized.
Approximately 39 percent of those shares were redeemed in connection with the public offering. The remaining shares are restricted because of unsettled litigation pending against Visa, Inc. Visa, Inc., at its discretion, may redeem additional shares
in order to resolve pending litigation.

The restriction expires upon resolution of the pending litigation. Accordingly, Suffolk has recorded
these shares at zero in the accompanying statement of condition. Upon expiration of the restriction, Suffolk expects to record the fair value of the remaining shares.

Management has considered factors such as market value, cash flows, and analysis of underlying collateral regarding
other-than-temporarily impaired securities and determined that there are no other-than-temporarily impaired securities as of December 31, 2010 and 2009.

The unrealized losses in collateralized mortgage obligations at December 31, 2010 were caused by a significant widening of credit spreads across markets for these securities, and illiquidity and
uncertainty in the financial markets. These securities include two private issues held at a continuous, unrealized loss for twelve months or longer. Each of these securities has some level of credit enhancement, and none are collateralized by
sub-prime loans. With the assistance of a third-party, management reviews the characteristics of these securities periodically, including levels of delinquency and foreclosure, projected losses at various de-grees of severity, and credit enhancement
and coverage. These securities are performing according to their terms, and, in the opinion of management, will continue to do so.

The
unrealized losses in municipal securities at December 31, 2010 were the result of uncertainty in the financial markets. These securities are performing according to their terms, and, in the opinion of management, will continue to do so.

Suffolk does not have the intent to sell these securities and does not anticipate that it will be necessary to sell these securities before
the full recovery of principal and interest due, which may be at maturity. Therefore, Suffolk did not consider these investments to be other-than-temporarily impaired at December 31, 2010.

This valuation allowance is included in the allowance for loan losses on the statements of condition.

The qualitative factors are determined based on the various risk characteristics of each loan class. Relevant risk characteristics are as follows:

Commercial, industrial and agricultural loans  Loans in this class are made to businesses. Generally these loans are secured by assets
of the business and repayment is expected from the cash flows of the business. A weakened economy, and resultant decreased consumer and/or business spending will have an effect on the credit quality in this loan class.

Commercial real estate  Loans in this class include income-producing investment properties and owner-occupied real estate used for business
purposes. The underlying properties are

##### Table of Contents

generally located largely in our primary market area. The cash flows of the income producing investment properties are adversely impacted by a downturn in the economy as evidenced by increased
vacancy rates, which in turn, will have an effect on credit quality. Generally management obtains annual financial information for borrowers with loans in excess of $1 million in this category. In the case of owner-occupied real estate used for
business purposes a weakened economy and resultant decreased consumer and/or business spending will have an adverse effect on credit quality.

Construction loans  Loans in this class primarily include land loans to local individuals, contractors and developers for developing the land for
sale or for the purpose of making improvements thereon. Repayment is derived from sale of the lots/ units including any pre-sold units. Credit risk is affected by market conditions, time to sell at an adequate price and cost overruns. To a lesser
extent this class includes commercial development projects we finance which in most cases have an interest-only phase during construction and then convert to permanent financing. Credit risk is affected by construction delays, cost overruns, market
conditions and the availability of permanent financing, to the extent such permanent financing is not being provided by us.

Residential real
estate  Loans in this class, including home equity loans, are made to and secured by owner-occupied residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy,
including unemployment rates and housing prices, will have an effect on the credit quality in this loan class. The Bank generally does not originate loans with a loan-to-value ratio greater than 80 percent and does not grant sub-prime loans.

Consumer loans  Loans in this class may be either secured or unsecured and repayment is dependent on the credit quality of the
individual borrower and, if applicable, sale of the collateral securing the loan (such as automobile, mobile home). Therefore the overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit
quality in this loan class.

CREDIT QUALITY INFORMATION

The Bank utilizes an eight grade risk rating system for commercial loans, commercial real estate and construction loans as follows:

Loans rated 1-4: Loans in these categories are considered pass rated loans with low to average risk.

Loans rated 5: Loans in this category are considered special mention. These loans contain one or more weaknesses that may be tolerated in the short run. Assets in this category are currently
protected but are potentially weak and are being closely monitored by management.

Loans rated 6: Loans in this category are considered
substandard. Generally, a loan is considered substandard if it is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged. There is distinct possibility that the Bank will sustain
some loss if the weakness is not corrected.

Loans rated 7: Loans in this category are considered doubtful. Loans classified as
doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make the collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly
questionable and improbable. The possibility of loss is extremely high; however, its classification as an estimated loss is deferred until a more exact determination of the extent of the loss is ascertained.

Loans rated 8: Loans in this category are considered uncollectible loss and of such little value that their continuance as loans is not
warranted.

The Bank considers real estate, home equity and consumer loans secured by real estate (such as mobile homes) that are
contractually past due 90 days or more or where legal action has commenced against the borrower to be substandard. The Bank follows the Federal Financial Institutions Examination Council (FFIEC) Uniform Retail Credit Classification
guidelines.

The Bank formally reviews the ratings on all commercial and industrial, commercial real estate and construction loans greater
than $1 million annually. Quarterly, the Bank engages an independent third-party to review a significant portion of loans within these segments. Management uses the results of these reviews as part of its annual review process.

##### Table of Contents

For purposes of borrowing, Suffolk has no assets pledged as collateral to the Federal Reserve Bank as of
December 31, 2010 and 2009. Assets pledged as collateral to the Federal Home Loan Bank (FHLB) as of December 31, 2010 and 2009 totaled $356,349,000 and $330,471,000, consisting of eligible loans and investment securities as
determined under FHLB borrowing guidelines.

Note 8  Stockholders Equity

Suffolk has a Dividend Reinvestment Plan. Stockholders can reinvest dividends in common stock of Suffolk at a 3 percent discount from market value on
newly issued shares. Shareholders may also make additional cash purchases at market value. There were 54,305, 30,498 and 13,969 shares issued in 2010, 2009 and 2008, respectively.

At December 31, 2010, Suffolk has a Stock Incentive Plan (the Plan) under which 500,000 shares of Suffolks common stock were originally reserved for issuance to key employees and
directors, and of which none have been issued at that date. Options are awarded by a committee appointed by the Board of Directors. The Plan provides that the option price shall not be less than the fair value of the common stock on the date the
option is granted. All options are exercisable for a period of ten years or less. The Plan provides for but does not require the grant of stock appreciation rights that the holder may exercise instead of the underlying option. When the stock
appreciation right is exercised, the underlying option is canceled. The optionee receives shares of common stock with a fair market value equal to the excess of the fair value of the shares subject to the option at the time of exercise (or the
portion thereof so exercised) over the aggregate option price of the shares set forth in the option agreement. The exercise of stock appreciation rights is treated as the exercise of the underlying option. Options vest after one year and expire
after ten years. Compensation (benefit) expense related to stock appreciation rights amounted to approximately ($253,000), ($174,000), and $104,000, for the years ended December 31, 2010, 2009, and 2008, respectively.

The following table presents the options granted, exercised, or expired during each of the past three years:

All dividends must conform to applicable statutory requirements. Under 12 USC 56-9, a national bank may not pay a dividend
on its common stock if the dividend would exceed net undivided profits then on hand. Further, under 12 USC 60, a national bank must obtain prior approval from the Office of the Comptroller of the Currency (OCC) to pay dividends on either
common or preferred stock that would exceed the banks net profits for the current year combined with retained net profits (net profits minus dividends paid during that period) from the prior two years. The ability of the Bank to pay dividends
to the Company is subject to certain regulatory restrictions. Generally, dividends declared in a given year by a national bank are limited to its net profit, as defined by regulatory agencies, for that year, combined with its retained net income for
the preceding two years, less any required transfer to surplus or to fund for the retirement of any preferred stock of which the Bank has none as of December 31, 2010. In addition, a national bank may not pay any dividends in an amount greater
than its undivided profits and a national bank may not declare any dividends if such declaration would leave the bank inadequately capitalized. Therefore, the ability of the Bank to declare dividends will depend on its future net income and capital
requirements. In addition, under the Agreement the

Please refer to Note 1 (Q) for further discussion on the three levels of fair value inputs to measure assets.

For pension assets, Level 1 securities consist primarily of short-term investment funds and equity securities which include investments in
common stock and depository receipts. Level 2 securities consist of fixed income securities including corporate bonds, government issues, and mortgage-backed securities. Level 3 securities include rights and warrants.

Investment Policies

The New York State
Bankers Retirement System (the System) was established in 1938 to provide for the payment of benefits to employees of participating banks. The System is overseen by a Board of Trustees who meet quarterly and set the investment policy
guidelines.

The System utilizes two investment management firms (which will be referred to as Firm I and Firm II), each investing
approximately 50 percent of the total portfolio. The Systems investment objective is to exceed the investment benchmarks in each asset category. Each firm operates under a separate written investment policy approved by the Trustees and
designed to achieve an allocation approximating 60 percent invested in equity securities and 40 percent invested in debt securities.

Each
Firm shall report at least quarterly to the Investment Committee and semiannually to the Board.

Equity Securities

The target allocation percentage for equity securities is from 40-60 percent at the investment managers discretion.

Firm I is employed for its expertise as a Value Manager. It is allowed to invest a certain amount of the equity portfolio under its management in
international securities and to hedge said international securities so as to protect against currency devaluations.

The equities managed by
Firm II are in a separately managed Large Cap Core Equity Fund. The portfolio is permitted to

invest in a diversified range of securities in the U.S. equity markets. Although the portfolio holds primarily common stocks, from time to time the portfolio may invest in other types of
investments on an opportunistic basis.

The System currently prohibits its investment managers from purchasing the following investments:
securities in emerging market countries as defined by the Morgan Stanley Emerging Markets Index, short sales, unregistered securities, and margin purchases.

Debt Securities

For both investment portfolios, the target allocation percentage for debt
securities is from 40-60 percent at the investment managers discretion.

The Fixed Income Portfolio managed by Firm I operates with
guidelines relating to types of debt securities, quality ratings, maturities, and maximum single and sector allocations.

The portfolio may
trade foreign currencies in both spot and forward markets to effect securities transactions and to hedge underlying asset positions. The purchase and sale of futures and options on futures on foreign currencies and on foreign and domestic bonds,
bond indices, and short-term securities is permitted; however, purchases may not be used to leverage the portfolio. Currency transactions may be used only to hedge 0-100 percent of currency exposure of foreign securities.

The Fixed Income portfolio managed by Firm II is a Core Bond Fixed Income Fund. The portfolio investments are limited to U.S. Dollar denominated,
fixed income securities and selective derivatives designed to have similar attributes of such fixed income securities. The term fixed income security is defined to include instruments with fixed, floating, variable, adjustable, auction
rate, zero, or other coupon features.

The System currently prohibits its investment managers from purchasing the following investments:
securities of BBB quality or less, CMOs that have an inverse floating rate and whose payments dont include principal or which arent certified and guaranteed by the U.S. Government, ABSs that arent issued or guaranteed
by the U.S., or its agencies or its instrumentalities, Non-Agency residential subprime or ALT-A MBSs and structured notes.

Concentration

At December 31,
2010, the System held approximately $25,200,000 of the State Street Bank & Trust Company Short Term Investment Fund. This fund represented 11.0 percent of the Systems total investments. Suffolks portion of this investment is
$3,616,000 at December 31, 2010.

Expected Long-Term Rate of Return

The expected long-term rate of return on plan assets reflects long-term earnings expectations on existing plan assets and those contributions expected to be received during the current plan year. In
estimating that rate, appropriate consideration was given to historical returns earned by plan assets in the fund and the rates of return expected to be available for reinvestment. Average rates of return over the past one-, three-, five-, and
ten-year periods were determined and subsequently adjusted to reflect current capital market assumptions and changes in investment allocations.

(B) Directors Retirement Income Agreement of the Bank of the Hamptons  On April 11, 1994, Suffolk acquired Hamptons Bancshares,
Inc., which had a directors deferred compensation plan. The liability for this plan was approximately $124,000 and $137,000 on December 31, 2010 and 2009. Interest (approximately $11,000 in 2010, $13,000 in 2009, and $14,000 in 2008) is
accrued over the term of the plan. In 2010, the Bank paid approximately $23,000 to participants.

(C) Deferred Compensation

1986 Plan In 1986, the Board approved a deferred compensation plan. Under the plan, certain employees and Directors of Suffolk elected to
defer compensation aggregating approximately $177,000 in exchange for stated future payments to be made at specified dates. The rate of return on the initial deferral was guaranteed. For purposes of financial reporting, interest (approximately
$119,000 in 2010, $71,000 in 2009, and $268,000 in 2008) at the plans contractual rate is being accrued on the deferral amounts over the expected plan term.

During 2010, Suffolk made payments of approximately $119,000 to participants of the plan. Suffolk has purchased life insurance policies on the plans participants based upon reasonable actuarial
benefit and other financial assumptions where the present value of the projected cash flows from the insurance proceeds approximates the present value of the projected cost of the employee benefit. Suffolk is the named beneficiary on the policies.
Net insurance (expense) income related to the policies aggregated approximately ($7,000), $17,000, and $222,000, in 2010, 2009, and 2008, respectively.

1999 PlanIn 1999, the Board approved a non-qualified deferred compensation plan. Under this plan, certain employees and Directors of Suffolk may elect to defer some or all of their
compensation in exchange for a future payment of the compensation deferred, with accrued interest, at retirement. During 2010, participants deferred compensation totaling $147,000. During 2010, payments of $228,000 have been made to the
participants.

Benefit assumptions are based on sponsor contributions of $0.27 per participant per month per $1,000 of life insurance. The
retiree is responsible for the premiums, less sponsor contributions. The Bank no longer contributes towards a retiree health plan.

(E) 401(k) Retirement Plan

The
Bank has a 401(k) Retirement Plan and Trust (the 401(k) Plan). Employees who have attained the age of 21 and have completed one year of service have the option to participate. Employees may elect to contribute up to a dollar limit which
is set by law. The limit was $16,500 for 2010. The Bank will match one-half of the employees contribution up to a maximum of 6 percent of the employees annual gross compensation subject to the aforementioned limit. Employees are fully
vested in their own contributions, and the Banks matching contributions are fully vested once the participant has six years of service. Bank contributions under the 401(k) Plan amounted to $406,000, $396,000, and $377,000 in 2010, 2009, and
2008, respectively. The Bank funds all amounts when due. At December 31, 2010, contributions to the 401(k) Plan were invested in various bond, equity, money market, or diversified funds as directed by each employee. The 401(k) Plan does not allow
for investment in the Companys common stock.

Note 11  Commitments and Contingent Liabilities

In the normal course of business, there are various outstanding commitments and contingent liabilities, such as standby letters of credit and commitments
to extend credit, which are not reflected in the accompanying consolidated financial statements. No material losses are anticipated as a result of these transactions. Suffolk is contingently liable under standby letters of credit in the amount of
$24,430,000 and $30,769,000 at December 31, 2010 and 2009, respectively. Suffolk has commitments to make or to extend credit in the form of revolving open-end lines secured by one- to four-family residential properties, commercial real estate,
construction and land development loans, and lease financing arrangements in the amount of $123,672,000 and $148,309,000, and commercial loans of $33,889,000 and $39,885,000 as of December 31, 2010 and 2009, respectively.

In the opinion of management, based upon legal counsel, liabilities arising from legal proceedings against Suffolk would not have a significant effect on
the financial position of Suffolk.

During 2010, Suffolk was required to maintain minimum balances with the Federal Reserve Bank of New York
for reserve and clearing requirements of $2,500,000. These balances averaged $11,313,000 in 2010.

Total rental expense for the years ended
December 31, 2010, 2009, and 2008 amounted to $1,644,000, $1,633,000, and $1,319,000, respectively.

At December 31, 2010, Suffolk
was obligated under a number of non-cancelable leases for land and buildings used for bank purposes. Minimum annual rentals, exclusive of taxes and other charges under non-cancelable operating leases, are summarized as follows: (in thousands)

Note 12  Regulatory Capital

The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements
can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Banks financial statements. Under capital adequacy guidelines and the regulatory
framework for prompt corrective action, the Bank must meet specific capital requirements that involve quantitative measures of the Banks assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices.
The Banks capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital (as
defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2010, that the Bank meets all capital adequacy requirements to which it
is subject.

The Bank is also subject to individual minimum capital ratios established by the OCC requiring the Bank to maintain Tier 1
capital ratio of at least equal to 8.00 percent of adjusted total assets, to maintain a Tier 1 capital ratio at least equal to 10.50 percent of risk-weighted assets, and to maintain a total risk based capital ratio at least equal to 12.00 percent of
risk-weighted assets. At December 31, 2010, the Bank met all three capital ratios. The Bank remains well-capitalized for regulatory purposes as of December 31, 2010.

The Banks actual capital amounts and ratios are also presented in the following table: (dollars in thousands)

Note 13  Credit Concentrations

Suffolks principal investments are loans and a portfolio of short- and medium-term debt of the United States Treasury, states and other political subdivisions, U.S. government agencies,
corporations, and mortgage-backed securities and collateralized mortgage obligations.

Loans secured by real estate comprise 71.3 percent of
the portfolio and 49.4 percent of assets, 31.9 percent of which are for commercial real estate. Commercial real estate loans present greater risk than residential mortgages. Suffolk has attempted to minimize the risks of these loans by considering
several factors, including the creditworthiness of the borrower, location, condition, value, and the business prospects for the security property. Commercial, financial, and agricultural loans, unsecured or secured by collateral other than real
estate, comprise 22.5 percent of the loan portfolio and 15.6 percent of assets. These loans present significantly greater risk than other types of loans. Average credits are greater in size than consumer loans, and unsecured loans may be more
difficult to collect. Suffolk obtains, whenever possible, both the personal guarantees of the principal(s) and cross-guarantees among the principals business enterprises. Consumer loans, net of unearned discounts, comprised 6.1 percent of
Suffolks loan portfolio and 4.2 percent of assets. A majority are indirect dealer-generated loans secured by automobiles. Most of these loans are made to residents of Suffolks primary lending area. Each loan is small in amount. Borrowers
represent a cross-section of the population and are employed in a variety of industries. The risk presented by any one loan is correspondingly small, and therefore, the risk that this portion of the portfolio presents to Suffolk depends on the
financial stability of the population as a whole, not any one entity or industry.

Municipal obligations constitute 52.4 percent of the
investment portfolio and 13.2 percent of assets. These obligations present slightly greater risk than U.S. Treasury securities, or those secured by the U.S. government, but significantly less risk than loans because they are backed by the full faith
and taxing power of the issuer, most of which is located in the state of New York. U.S. Treasury securities represented 2.0 percent of the investment portfolio and 0.5 percent of assets. U.S. government agency debt securities represented 5.5 percent
of the investment portfolio and 1.4 percent of assets. These offer little or no financial risk. Collateralized mortgage obligations represented 39.9 percent of the investment portfolio and 10.0 percent of assets. These securities are backed by pools

gages; however, they provide more predictable cash flows because payments are assigned to specific tranches of securities in the order in which they are received. Suffolk invests in
senior tranches, which provides for prioritized receipt of cash flows. Mortgage-backed securities represented 0.1 percent of the investment portfolio and less than 0.03 percent of assets.

Note 14  Fair Value of Financial Instruments

The following table presents the
carrying amounts and fair values of Suffolks financial instruments. FASB ASC 825, Financial Instruments, defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current
transaction between willing parties, other than in a forced sale or liquidation: (in thousands)

Limitations

The following estimates are made at a specific point in time and may be based on judgments regarding losses expected in the future, risk, and other
factors that are subjective in nature. The methods and assumptions used to produce the fair value estimates follow.

Short-Term Instruments

Short-term financial instruments are valued at the carrying amounts included in the statements of condition, which are reasonable
estimates of fair value due to the relatively short term of the instruments. This approach applies to cash and cash equivalents; federal funds purchased; accrued interest receivable; non-interest-bearing demand deposits; N.O.W., money market, and
saving accounts; accrued interest payable; and other borrowings. Federal Home Loan Bank advances/borrowings are measured using a discounted replacement cost of funds approach.

Loans

Fair values are estimated for portfolios of loans with similar characteristics.
Loans are segregated by type.

The fair value of performing loans was calculated by discounting scheduled cash flows through the estimated
maturity using estimated market discount rates that reflect the credit and interest rate risk of the loan. Estimated maturity is based on the Banks history of repayments for each type of loan and an estimate of the effect of the current
economy.

Fair value for significant non-performing loans is based on recent external appraisals of collateral, if any. If appraisals are not
available, estimated cash flows are discounted using a rate commensurate with the associated risk. Assumptions regarding credit risk, cash flows, and discount rates are made using available market information and specific borrower information.

Mortgage servicing rights are measured at fair value on a recurring basis.

Other real estate owned is recorded at fair value, less estimated selling costs, and are therefore measured at fair value on a non-recurring basis. Other
real estate owned is classified at level 3 in the fair value hierarchy. Fair value is measured based on independent third-party appraisals, assets acquired through foreclosure are recorded as held for sale initially at the lower of the recorded
investment in the loan or fair value less estimated selling costs, upon the date of foreclosure. Subsequent to foreclosure, valuations are updated periodically and the carrying value of these assets may be reduced further.

Impaired loans are evaluated and valued at the time the loan is identified as impaired, at the lower of cost or market value, and classified at level 3
in the fair value hierarchy. Market value is measured based on the value of the collateral securing these loans or techniques that are not supported by market activity for loans that are not collateral-dependent and require managements
judgment. Collateral may be real estate and/or business assets including equipment, inventory, and/or accounts receivable. The value of real estate collateral is determined based on appraisals by qualified licensed appraisers hired by Suffolk. The
value of business equipment may be based on an appraisal by qualified licensed appraisers hired by Suffolk if significant, or may be valued based on the equipments net book value on the business financial statements. Inventory and
accounts receivable collateral may be valued based on independent field examiner review or aging reports, if significant.

Field examiner
reviews may be conducted based on the loan exposure and reliance on this type of collateral. Appraised and reported values may be discounted based on managements historical knowledge, changes in market conditions from the time of valuation,
and/or managements expertise and knowledge of the client and clients business. Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors
identified above.

The types of instruments valued based on quoted market prices in active markets include most U.S. government debt and agency
debt securities. Such instruments are generally classified within level 1 or level 2 of the fair value hierarchy. Suffolk does not adjust the quoted price for such instruments.

The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency include
state and municipal obligations, mortgage-backed securities and collateralized mortgage obligations. Such instruments are generally classified within level 2 of the fair value hierarchy.

FASB ASC 820, Fair Value Measurements and Disclosures, provides additional guidance in determining fair values when the volume and level of activity for the asset or liability have
significantly decreased, particularly when there is no active market or where the price inputs being used represent distressed sales. It also provides guidelines for making fair value measurements more consistent with principles, reaffirming the
need to use judgment to ascertain if a formerly active market has become inactive and in determining fair values when markets become inactive. Suffolk adopted this codification effective April 1, 2009. The adoption did not have a material
impact on Suffolks financial condition and results of operations. The additional disclosures are included herein.

Deposit
Liabilities

The fair value of certificates of deposit less than $100,000 was calculated by discounting cash flows with applicable
origination rates. At December 31, 2010, the fair value of certificates of deposit less than $100,000 totaling $98,145,000 had a carrying value of $97,199,000. At December 31, 2010, the fair value of certificates of deposit of $100,000 or
more totaling $211,772,000 had a carrying value of $210,096,000.

Commitments to Extend Credit, Standby Letters of Credit, and Written Financial Guarantees

The fair value of commitments to extend credit was estimated by either discounting cash flows or using the fees currently charged to enter into similar
agreements, taking into account the remaining terms of the agreements and the current creditworthiness of the counter-parties.

Credit in the
form of revolving open-end lines secured by one- to four-family residential properties, commercial real estate, construction and land development loans, and lease financing arrangements was $123,672,000 and $148,309,000 as of December 31, 2010
and 2009, respectively.

The estimated fair value of written financial guarantees and letters of credit is based on fees currently charged for
similar agreements. The contractual amounts of these commitments were $58,319,000 and $70,654,000 at December 31, 2010 and 2009, respectively. The fees charged for the commitments were not material in amount.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and

Shareholders of Suffolk
Bancorp

We have audited Suffolk Bancorp (a New York corporation) and subsidiaries internal control over financial reporting as of
December 31, 2010, based on criteria established in Internal ControlIntegrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Suffolk Bancorps management is responsible for
maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Managements Report on Internal Control over Financial Reporting. Our
responsibility is to express an opinion on Suffolk Bancorps internal control over financial reporting based on our audit.

We conducted
our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over
financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and
operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed 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. A companys internal control over financial reporting includes those policies and procedures that
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors
of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Suffolk Bancorp and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2010, based on criteria established in Internal ControlIntegrated Frameworkissued by COSO.

We also have
audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated statements of condition of Suffolk Bancorp and subsidiaries as of December 31, 2010 and 2009, and the related
consolidated statements of income, changes in stockholders equity, and cash flows for each of the three years in the period ended December 31, 2010 and our report dated March 15, 2011 expressed an unqualified opinion.

and cash flows for each of the three years in the period ended December 31, 2010. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements
based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Suffolk Bancorp and subsidiaries as of December 31, 2010 and 2009, and the results of their operations and their cash flows for each of the three years in the period ended
December 31, 2010 in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in
accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Suffolk Bancorp and its subsidiaries internal control over financial reporting as of December 31, 2010, based on criteria

Board of Directors and

Shareholders of Suffolk Bancorp

The management of Suffolk Bancorp is responsible for the preparation and integrity of the consolidated financial statements and all other information in

PART I



|ITEM 1. | Business
|------- | --------

Suffolk
Bancorp (Suffolk)

Suffolk was incorporated on January 2, 1985 as a bank holding company. On that date, Suffolk acquired,
and currently owns, all of the outstanding capital stock of Suffolk County National Bank. On July 14, 1988, Suffolk acquired all the outstanding capital stock of Island Computer Corporation of New York, Inc. The business of Suffolk consists
primarily of the ownership, supervision, and control of its subsidiaries. On April 11, 1994, Suffolk acquired all the outstanding capital stock of Hamptons Bancshares, Inc. and merged it into a subsidiary. During 1996, the operations of Island
Computer Corporation of New York, Inc. were assumed by Suffolk County National Bank.

Suffolks chief competition includes local banks
with main or branch offices in the service area of Suffolk County National Bank, including Peoples United Bank and Bridgehampton National Bank. Additionally, New York City money center banks and regional banks provide competition. These banks
include primarily Capital One, Citibank, Bank of America, JPMorgan Chase & Co., TD Bank, and Hudson City Savings.

Suffolk and its
subsidiaries had 360 full-time and 54 part-time employees on December 31, 2010.

Suffolk County National Bank (the
Bank)

The Suffolk County National Bank of Riverhead was organized under the national banking laws of the United States of
America on January 6, 1890. The Bank is a member of the Federal Reserve System, and its deposits are insured by the Federal Deposit Insurance Corporation to the extent provided by law.

Directed by members of the communities it serves, the Banks main service area includes the towns of Babylon, Brookhaven, East Hampton, Islip, Riverhead, Smithtown, Southampton, and Southold. The
main office of the Bank is situated at 6 West Second Street, Riverhead, New York. Its branch offices are located at Amityville, Bohemia, Center Moriches, Cutchogue, Deer Park, East Hampton, Hampton Bays, Hauppauge, Manorville, Mattituck, Medford,
Middle Island, Miller Place, Montauk, Port Jefferson, Port Jefferson Station, Riverhead, Sag Harbor, Sayville, Shoreham, Smithtown, Southampton, Wading River, Water Mill, West Babylon, and Westhampton Beach, New York.

The Bank is a full-service bank serving the needs of the local residents of Suffolk County. Most of the Banks business is devoted to serving those
residing in the immediate area of the Banks main and branch offices. Among the services offered by the Bank are checking accounts, savings accounts, time and savings certificates, money market accounts, negotiable-order-of-withdrawal accounts,
holiday club accounts, and individual retirement accounts; secured and unsecured loans, including commercial loans to individuals, partnerships, and corporations, agricultural loans to farmers, installment loans to finance small businesses, and
automobile loans; home equity and real estate mortgage loans; safe deposit boxes; trust and estate services; the sale of mutual funds and annuities; and the maintenance of a master pension plan for self-employed individuals participation. The
business of the Bank is only mildly seasonal.

BUSINESS SEGMENT REPORTING

Suffolk County National Bank is a regional bank, which offers a wide array of products and services to its customers. Pursuant to its banking strategy,
emphasis is placed on building relationships with its customers, as opposed to building specific lines of business. As a result, at December 31, 2010 and 2009, Suffolk is not organized around discernible lines of business and prefers to work as
an integrated unit to customize solutions for its customers, with business line emphasis and product offerings changing over time as needs and demands change. See page 37 of this Annual Report to Shareholders for the fiscal year ended December 31,
2010.



AVAILABLE INFORMATION

Suffolk files Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, Proxy Statements on Form 14(a), and any
amendments to those reports, with the United States Securities and Exchange Commission (the SEC). The public may read and copy any of these materials at the SECs Public Reference Room at 100 F Street, NE, Washington, D.C. 20549.
Information on the operation of the Public Reference Room can be obtained by calling the SEC at 1-800-SEC-0330 (1-800-732-0330). The SEC also maintains an Internet site (http://www.sec.gov) that contains reports, proxy, and information statements,
and other information regarding issuers, including Suffolk, that file electronically with the SEC. Suffolk also makes these reports available free of charge through its Internet website (http://www.suffolkbancorp.com) as soon as practicably possible
after Suffolk files these reports electronically with the SEC.

SUPERVISION AND REGULATION

References in this section to applicable statutes and regulations are brief summaries only, and do not purport to be complete. The reader should
consult such statutes and regulations themselves for a full understanding of the details of their operation.

As a consequence of the
extensive regulation of commercial banking activities in the United States, the business of Suffolk and its subsidiaries is particularly susceptible to federal and state legislation that may have the effect of increasing or decreasing the cost of
doing business, modifying permissible activities, or enhancing the competitive position of other financial institutions.

Suffolk is a bank
holding company registered under the Bank Holding Company Act (BHCAct) and is subject to supervision and regulation by the Federal Reserve Board. Federal laws subject bank holding companies to particular restrictions on the types of
activities in which they may engage, and to a range of supervisory requirements and activities, including regulatory enforcement actions for violation of laws and policies.



59



---

##### Table of Contents

Activities Closely Related to Banking

The BHC Act prohibits a bank holding company, with certain limited exceptions, from acquiring direct or indirect ownership or control of any voting
shares of any company that is not a bank or from engaging in any activities other than those of banking, managing or controlling banks and certain other subsidiaries, or furnishing services to or performing services for its subsidiaries. One
principal exception to these prohibitions allows the acquisition of interests in companies whose activities are found by the Federal Reserve Board, by order or regulation, to be closely related to banking, or managing or controlling banks. If a bank
holding company has become a Financial Holding Company (a FHC), it may engage in activities that are jointly determined by the Federal Reserve Board and the Treasury Department to be financial in nature or incidental to
such financial activity. FHCs may also engage in activities that are determined by the Federal Reserve to be complementary to financial activities. See Gramm-Leach-Bliley Act for a brief summary of the statutory
provisions relating to FHCs.

Safe and Sound Banking Practices

Bank holding companies are not permitted to engage in unsafe and unsound banking practices. The Federal Reserve Board may order a bank holding company to
terminate an activity or control of a nonbank subsidiary if such activity or control constitutes a significant risk to the financial safety, soundness, or stability of a subsidiary bank and is inconsistent with sound banking principles. Regulation Y
also requires a holding company to give the Federal Reserve Board prior notice of any redemption or repurchase of its own equity securities, if the consideration to be paid, together with the consideration paid for any repurchases or redemptions in
the preceding year, is equal to 10 percent or more of the companys consolidated net worth.

The Federal Reserve Board has broad
authority to prohibit activities of bank holding companies and their non-banking subsidiaries which represent unsafe and unsound banking practices or which constitute violations of laws or regulations. Notably, the Financial Institutions Reform,
Recovery and Enforcement Act of 1989 (FIRREA) provides that the Federal Reserve Board can assess civil money penalties for such practices or violations, which can be as high as $1 million per day. FIRREA contains expansive provisions
regarding the scope of individuals and entities against which such penalties may be assessed.

Annual Reporting and
Examinations

Suffolk is required to file an annual report with the Federal Reserve Board, and such additional information as the Federal
Reserve Board may require pursuant to the BHC Act. The Federal Reserve Board may examine a bank holding company or any of its subsidiaries, and charge the company for the cost of such an examination. Suffolk is also subject to reporting and
disclosure requirements under state and federal securities laws.

Imposition of Liability for Undercapitalized Subsidiaries

The Federal Deposit Insurance Corporation Improvement Act of 1991 (FDICIA) required each federal banking agency to revise its
risk-based capital standards to ensure that those standards take adequate account of interest rate risk, concentration of credit risk, and the risks of nontraditional activities, as well as reflect the actual performance and expected risk of loss on
multifamily mortgages. In accordance with the law, each federal banking agency has specified, by regulation, the levels at which an insured institution would be considered well capitalized, adequately capitalized,
undercapitalized, significantly undercapitalized, and critically undercapitalized. Under these regulations, as of December 31, 2010, the Bank would be deemed to be well capitalized.

FDICIA requires bank regulators to take prompt corrective action to resolve problems associated with insured depository institutions. In the
event an institution becomes undercapitalized, it must submit a capital restoration plan. If an institution becomes significantly undercapitalized or critically undercapitalized, additional and significant
limitations are placed on the institution. The capital restoration plan of an undercapitalized institution will not be accepted by the regulators unless each company having control of the undercapitalized institution
guarantees the subsidiarys compliance with the capital restoration plan until it becomes adequately capitalized. Suffolk has control of the Bank for the purpose of this statute.

Additionally, Federal Reserve Board policy discourages the payment of dividends by a bank holding company from borrowed funds as well as payments that
would adversely affect capital adequacy. Failure to meet the capital guidelines may result in supervisory or enforcement actions by the Federal Reserve Board.

Acquisition by Bank Holding Companies

The BHC Act requires every bank holding company to
obtain the prior approval of the Federal Reserve Board before it may acquire all or substantially all of the assets of any bank, or ownership or control of any voting shares of any bank, if after such acquisition it would own or control, directly or
indirectly, more than 5 percent of the voting shares of such bank. In approving bank acquisitions by bank holding companies, the Federal Reserve Board is required to consider the financial and managerial resources and future prospects of the bank
holding company and banks concerned, the convenience and needs of the communities to be served, and the effect on competition. The Attorney General of the United States may, within 30 days after approval of an acquisition by the Federal Reserve
Board, bring an action challenging such acquisition under the federal antitrust laws, in which case the effectiveness of such approval is stayed pending a final ruling by the courts. Under certain circumstances, the 30-day period may be shortened to
15 days.

Interstate Acquisitions

Under the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994, beginning September 29, 1995, bank holding companies may acquire banks in any state subject to limited restrictions
including bank age and deposit concentration limits,



60

notwithstanding contrary state law. All banks owned in common by a bank holding company may act as agents for one another. An agent bank may receive deposits, renew time deposits, accept
payments, and close and service loans for its principal bank and not be considered to be a branch of the principal banks.

Banks also may
merge with banks in another state and operate either office as a branch, preexisting contrary state law notwithstanding. This law became effective automatically in all states on June 1, 1997, unless a state, by legislation enacted before
June 1, 1997, opted out of coverage by the interstate branching provision. Upon consummation of an interstate merger, the resulting bank may acquire or establish branches on the same basis that any participant in the merger could have if the
merger had not taken place.

Banks may also merge with branches of banks in other states without merging with the banks themselves, or may
establish de novo branches in other states if the laws of the other states expressly permit such mergers or such interstate de novo branching.

Banking Regulation

The Bank is a national bank, which is subject to regulation and
supervision primarily by the Office of the Comptroller of the Currency (the OCC) and secondarily by the Federal Reserve Board and the Federal Deposit Insurance Corporation (the FDIC). The Bank is subject to the requirements
and restrictions under federal law, including requirements to maintain reserves against deposits, restrictions on the types and amounts of loans that may be granted and the interest that may be charged thereon, and limitations on the types of
investments that may be made and the types of services that may be offered. Various consumer laws and regulations also affect the operations of the Bank.

Restrictions on Transactions with Affiliates

Section 23A of the Federal Reserve Act
imposes quantitative and qualitative limits on transactions between a bank and any affiliate, and requires certain levels of collateral for such loans. It also limits the amount of advances to third parties which are collateralized by the securities
or obligations of Suffolk or its subsidiaries.

Section 23B requires that certain transactions between the Bank and its affiliates must
be on terms substantially the same, or at least as favorable, as those prevailing at the time for comparable transactions with or involving other nonaffiliated companies. In the absence of such comparable transactions, any transaction between the
Bank and its affiliates must be on terms and under circumstances, including credit standards, that in good faith would be offered to or would apply to nonaffiliated companies.

Examinations

The OCC regularly examines the Bank and records of the Bank. The FDIC may
also periodically examine and evaluate insured banks. In addition, the Federal Reserve Board regularly examines the Bank and records of Suffolk.

Standards for Safety and Soundness

As part of the FDICIAs efforts to promote the
safety and soundness of depository institutions and their holding companies, appropriate federal banking regulators are required to have in place regulations specifying operational and management standards (addressing internal controls, loan
documentation, credit underwriting, and interest rate risk), asset quality, and earnings. In addition, the Federal Reserve Board, the OCC, and FDIC have extensive authority to police unsafe or unsound practices and violations of applicable laws and
regulations by depository institutions and their holding companies. For example, the FDIC may terminate the deposit insurance of any institution that it determines has engaged in an unsafe or unsound practice. The agencies can also assess civil
money penalties of up to $1 million per day, issue cease-and-desist or removal orders, seek injunctions, and publicly disclose such actions.

The Gramm-Leach-Bliley Act, effective on March 11, 2000,
permits bank holding companies to become FHCs and, by doing so, affiliate with securities firms and insurance companies and engage in other activities that are financial in nature or complementary thereto. A bank holding company may become a FHC, if
each of its subsidiary banks is well capitalized under the FDI-CIA prompt corrective action provisions, is well managed, and has at least a satisfactory rating under the Community Reinvestment Act as of 1977 as
amended (the CRA), by filing a declaration that the bank holding company wishes to become a FHC and meets all applicable requirements.

No prior regulatory approval is required for a FHC to acquire a company, other than a bank or savings association, engaged in activities permitted under the Gramm-Leach-Bliley Act. Activities specified in
the Gramm-Leach-Bliley Act as being financial in nature include securities underwriting and dealing, and insurance underwriting and agency activities. Activities that the Federal Reserve Board has determined to be closely related to
banking are also deemed to be financial in nature.

A national bank also may engage, subject to limitations on investment, in activities that
are financial in nature, other than insurance underwriting, merchant banking, real estate development, and real estate investment, through a financial subsidiary of the bank, if the bank is well capitalized, well managed, and
has at least a satisfactory CRA rating. Subsidiary banks of a FHC or national bank with financial subsidiaries must continue to be well capitalized and well managed in order to continue to engage in such activities without regulatory
actions or restrictions, which could include divestiture of the financial subsidiary or subsidiaries. In addition, a FHC or a bank may not acquire a company that is engaged in such activities unless each of the subsidiary banks of the FHC or the
bank has at least a satisfactory rating. At December 31, 2010, the Bank was rated as outstanding.

In July of
2001, provisions of the Gramm-Leach-Bliley Act became effective that impose additional requirements on financial institutions with respect to customer privacy. These provisions generally prohibit disclosure of customer information to

nonaffiliated third parties unless the customer has been given the opportunity to object, and has not objected, to such disclosure. Financial institutions are also required to disclose their
privacy policies to customers annually and may be required to comply with provisions of applicable state law if such provisions are more protective of customer privacy than those contained in the Gramm-Leach-Bliley Act.

Emergency Economic Stabilization Act of 2008

On October 3, 2008, the Emergency Economic Stabilization Act of 2008 (EESA) was signed into law. EESAs stated purpose is to provide the Secretary of the U.S. Treasury (the
Secretary) with the authority and facilities to restore liquidity and stability to the United States financial system and to ensure that such authority and facilities are used to protect home values, college funds, retirement accounts
and life savings, preserve homeownership and promote jobs and economic growth, maximize overall returns to U.S. taxpayers and provide accountability for the Secretarys exercise of such authority.

EESA includes a federal program to purchase troubled mortgages and financial instruments from financial institutions, which is referred to as the
Troubled Asset Relief Program (TARP). EESA also includes provisions that place limits on executive pay practices by institutions participating in the TARP, measures to facilitate acquisitions of financial institutions with troubled
assets without government assistance, temporary enhancements to the federal deposit insurance program, enhanced tax benefits for losses incurred in the sale of certain assets, possible relief from fair value accounting, and an acceleration of the
date on which the Board of Governors of the Federal Reserve System (FRB) can pay interest to banks on reserves on deposit with the FRB. On October 6, 2008, the FRB stated that it will begin paying interest on both excess and
required reserves on October 9, 2008. The Bank maintains funds on deposit at the Federal Reserve Bank of New York, and each has received interest on these deposits since October 9, 2008.

The Secretary utilized his authority under the TARP to invest in preferred stocks of financial institutions under a Capital Purchase Program
(CPP). Under the CPP, we were eligible to submit an application for between $12.3 million and $36.1 million. After careful analysis, we chose to not submit an application for any TARP funds. EESA immediately raised the FDIC insurance
limit from $100,000 to $250,000, which increase was made permanent by the Dodd-Frank Wall Street Reform and Consumer Protection Act.

EESA
also provides that gains or losses from the sale or exchange of Fannie Mae and Freddie Mac preferred stocks by an applicable institution (which includes banks, thrifts and their holding companies) shall be treated as ordinary gains or losses.
Previously, these gains or losses were treated as capital gains or losses. This provision allows applicable institutions to deduct losses realized on the sale of the preferred stocks of Fannie Mae and Freddie Mac. Prior to the passage of the Act,
the tax deductibility of these losses for us was limited to offset capital gains. Due to the provisions of the tax code, we have a limited ability to realize capital gains other than from the sale of our facilities. We do not hold any preferred
stock of either Fannie Mae or Freddie Mac.

The FDIC adopted the Temporary Liquidity Guarantee Program to free up credit markets and maintain
confidence in uninsured transaction accounts. The FDIC guaranteed senior unsecured debt issued between October 14, 2008 and October 31, 2009. The insurance will run through June 30, 2012. The annualized guarantee fee is a 75 basis
point charge of the debt issued. All FDIC-insured institutions were eligible for the program, except troubled institutions and a small number of grandfathered savings and loan holding companies with commercial owners. The FDIC also
provided full insurance coverage for non-interest bearing transaction accounts and NOW accounts with interest rates no higher than 50 basis points at insured institutions through December 31, 2009 under the Transaction Account Guarantee Program
(the TAGP). The cost was a 10 basis point annualized charge on amounts in excess of $250,000. Both programs had no cost for the first 30 days. After that, institutions remained in the program unless they notified the FDIC that they were
opting out of one or both programs by December 12, 2008. Those institutions were not allowed to opt back in. Participating banks in both programs are subject to enhanced supervisory oversight to prevent rapid growth or excessive risk-taking. If
the costs of the programs are not covered by the special fees, all FDIC-insured institutions will be assessed even if they did not participate in the programs. The Bank opted to participate in these programs. The TAGP was subsequently extended
through December 31, 2010. The extension increased the rate institutions paid to 15 basis points, 20 basis points or 25 basis points, depending on the risk category assigned to the institution under the FDICs risk-based premium system.

The American Recovery and Reinvestment Act of 2009

On February 17, 2009, the American Recovery and Reinvestment Act of 2009 (the Stimulus Act) was signed into law. The purpose of the Stimulus Act is to provide stimulus for the U.S.
economy. The Stimulus Act provided additional restrictions and standards throughout the period during which an institutions obligations under the CPP remained outstanding, including:



| |  |  | Limits on compensation incentives for risk taking by senior executive officers;
| | - |  | -------------------------------------------------------------------------------



| |  |  | Recovery of any compensation paid based on inaccurate financial information;
| | - |  | ----------------------------------------------------------------------------

| |  |  | Prohibition on compensation plans that would encourage manipulation of reported earnings to enhance the compensation of employees;

| |  |  | Publicly registered TARP recipients must establish a board compensation committee comprised entirely of independent directors, for the purpose of
reviewing employee compensation plans;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Prohibition on bonuses, retention awards, or incentive compensation, except for payments of long term restricted stock;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | Limitation on luxury expenditures;
| | - |  | ----------------------------------



| |  |  | TARP recipients may be required to permit a separate shareholder vote to approve the compensation of executives, as disclosed pursuant to the
SECs compensation disclosure rules; and

The Stimulus Act required the Secretary to issue additional regulations governing executive
compensation at institutions participating in the CPP. These regulations did not have a significant effect on our operations as we did not participate in the CPP program as noted above.

The Dodd-Frank Wall Street Reform and Consumer Protection Act

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act), signed into law on July 21, 2010, makes extensive changes to the laws regulating financial services
firms. The Dodd-Frank Act also requires significant rulemaking and mandates multiple studies which could result in additional legislative or regulatory action. Under the Dodd-Frank Act federal banking regulatory agencies are required to draft and
implement enhanced supervision, examination and capital standards for depository institutions and their holding companies. The enhanced requirements include, among other things, changes to capital, leverage and liquidity standards and numerous other
requirements. The Dodd-Frank Act authorizes various new assessments and fees, expands supervision and oversight authority over non-bank subsidiaries, increases the standards for certain covered transactions with affiliates and requires the
establishment of minimum leverage and risk-based capital requirements for insured depository institutions. The Dodd-Frank Act also establishes a new federal Consumer Financial Protection Bureau with broad authority and permits states to adopt
stricter consumer protection laws and enforce consumer protection rules issued by the Consumer Financial Protection Bureau. Due to the passage of the Dodd-Frank Act, all deposits held in non-interest-bearing transaction accounts will be fully
insured, regardless of the amount in the account. Interest-bearing transaction and non-transaction accounts will be subject to coverage up to $250,000 per depositor, per insured bank, for each account ownership category. Effective for the FDIC
insurance assessment payable September 30, 2011, which covers the second quarter of 2011, the FDIC assessment will be based on the Banks total average assets less Tier 1 capital, instead of deposits. The assessment on average assets will
be computed at lower rates, which may result in lower deposit premiums beginning in the second quarter of 2011.

Governmental Monetary Policies and Economic Conditions

The principal sources of funds essential to the business of banks and bank holding companies are deposits, stockholders equity, and borrowed funds. The availability of these various sources of funds
and other potential sources, such as preferred stock or commercial paper, and the extent to which they are utilized, depends on many factors, the most important of which are the Federal Reserve Boards monetary policies and the relative costs
of different types of funds. An important function of the Federal Reserve Board is to regulate the national supply of bank credit in order to combat recession and curb inflationary pressure. Among the instruments of monetary policy used by the
Federal

Reserve Board to implement these objectives are open market operations in United States government securities, changes in the
discount rate on bank borrowings, and changes in reserve requirements against bank deposits. The monetary policies of the Federal Reserve Board have had a significant effect on the operating results of commercial banks in the past and are expected
to continue to do so in the future. In view of the recent changes in regulations affecting commercial banks and other actions and proposed actions by the federal government and its monetary and fiscal authorities, including proposed changes in the
structure of banking in the United States, no prediction can be made as to future changes in interest rates, availability of credit, deposit balances, or the overall performance of banks generally or of Suffolk and its subsidiaries in particular.



|ITEM 1A. | Risk Factors
|-------- | ------------

Our results may be
adversely affected if we continue to suffer higher than expected losses on our loans or are required to further increase our allowance for loan losses.

We assume credit risk from the possibility that we will suffer losses because borrowers, guarantors, and related parties fail to perform under the terms of their loans. We try to minimize and monitor this
risk by adopting and implementing what we believe are effective underwriting and credit policies and procedures, including how we establish and review the allowance for loan losses. The allowance for loan losses is determined by continuous analysis
of the loan portfolio and the analytical process is regularly reviewed and adjustments may be made based on the assessments of internal and external influences on credit quality. Those policies and procedures may still not prevent unexpected losses
that could adversely affect our results. Weak economic conditions could adversely impact the ability of borrowers to repay outstanding loans or the value of collateral securing those loans. In addition, deterioration in economic conditions affecting
borrowers, new information regarding existing loans, identification of additional problem loans, changes in regulation and regulatory interpretation and other factors, both within and outside of our control, may require an increase in the allowance
for loan losses. See the sections captioned Loan Portfolio, Non-Performing Loans and Summary of Loan Losses and Allowance for Loan Losses beginning on page 13 of this report and Note 1(D) and Note 4 to our
Consolidated Financial Statements contained in this report for further discussion related to our loan portfolio and our process for determining the appropriate level of the allowance for loan losses. As required by the Agreement with the OCC,
Suffolk is in the process of reviewing its allowance for loan losses which may result in further increases to the allowance.

Recent
financial reforms and related regulations may affect our results of operations, financial condition or liquidity.

The Dodd-Frank Act,
signed into law on July 21, 2010, makes extensive changes to the laws regulating financial services firms. The Dodd-Frank Act also requires significant rulemaking and mandates multiple studies which could result in

##### Table of Contents

additional legislative or regulatory action. For a Description of the Dodd-Frank Act see Supervision and RegulationThe Dodd Frank Wall Street Reform and Consumer Protection Act.
At this time, it is difficult to predict the extent to which the Dodd-Frank Act or the resulting regulations will impact Suffolks business. However, compliance with these new laws and regulations will likely result in additional costs, and
these additional costs may adversely impact our results of operations, financial condition or liquidity.

Failure to comply with the
Banks written agreement with the OCC may result in further regulatory enforcement actions.

On October 25, 2010, the Bank,
following discussion with the OCC, entered into an agreement with the OCC. The Agreement requires the Bank to take certain actions, including a review of management, the establishment of a three-year strategic plan and capital program, and the
establishment of programs related to internal audit, maintaining an adequate allowance for loan losses, real property appraisal, credit risk management, credit concentrations, Bank Secrecy Act compliance and information technology. While subject to
the Agreement, Suffolk expects that its and the Banks management and Board of Directors will be required to focus a substantial amount of time on complying with its terms. There also is no guarantee that the Bank will be able to fully comply
with the Agreement. If the Bank fails to comply with the terms of the Agreement, it could be subject to further regulatory enforcement actions.

While the Bank currently meets the three individual minimum capital ratios set by the OCC, further increases to our allowance for loan losses would
negatively impact our capital levels, causing the Bank to no longer be in compliance with such ratios.

The Bank is subject to individual
minimum capital ratios established by the OCC requiring the Bank to maintain a Tier 1 capital ratio of at least equal to 8.00 percent of adjusted total assets, to maintain a Tier 1 capital ratio at least equal to 10.50 percent of risk-weighted
assets, and to maintain a total risk based capital ratio at least equal to 12.00 percent of risk-weighted assets. At December 31, 2010, the Bank met all three capital ratios as the Bank had a Tier 1 leverage ratio of 8.64 percent, a Tier 1
risk-based capital ratio of 11.78 percent and a total risk-based capital ratio of 13.03 percent. Further increases to Suffolks allowance for loan losses, however, would negatively impact the Banks capital levels and make it difficult to
maintain the capital levels directed by the OCC. If the Bank fails to maintain the required capital levels, it could be subject to further regulatory enforcement actions.

As a bank holding company that conducts substantially all of its operations through its banking subsidiary, our ability to pay dividends to stockholders depends upon the results of operations of the
Bank and its ability to pay dividends to Suffolk. Dividends paid by the Bank are subject to limits imposed by law and regulation and are restricted by an agreement with the OCC.

Substantially all of our activities are conducted through the Bank, and Suffolk receives substantially all of its funds through dividends from the Bank. Suffolks ability to pay dividends to
stockholders depends on the Banks ability to pay dividends to Suffolk. Various laws and regulations limit the amount of dividends that the Bank may pay us. In addition, under the Agreement, the Bank is required to establish a dividend policy
that will permit the declaration of a dividend only when the Bank is in compliance with its capital program and with the prior written determination of no supervisory objection by the OCC. If the Bank is unable to pay dividends to Suffolk, we will
not be able to pay dividends to our stockholders.

Changes in interest rates could adversely affect Suffolks results of operations
and financial condition.

Our ability to generate net income depends primarily upon our net interest income. Net interest income is income
that remains after deducting, from total income generated by earning assets, the interest expense attributable to the acquisition of the funds required to support earning assets. Income from earning assets includes income from loans, investment
securities and short-term investments. The amount of interest income is dependent on many factors including the volume of earning assets, the general level of interest rates, the dynamics of the change in interest rates and the levels of
non-performing loans. The cost of funds varies with the amount of funds necessary to support earning assets, the rates paid to attract and hold deposits, rates paid on borrowed funds and the levels of non-interest-bearing demand deposits and equity
capital.

Different types of assets and liabilities may react differently, at different times, to changes in market interest rates. We expect
that we will periodically experience gaps in the interest rate sensitivities of our assets and liabilities. That means either our interest-bearing liabilities will be more sensitive to changes in market interest rates than our interest
earning assets, or vice versa. When interest-bearing liabilities mature or re-price more quickly than interest-earning assets, an increase in market rates of interest could reduce our net interest income. Likewise, when interest-earning assets
mature or re-price more quickly than interest-bearing liabilities, falling interest rates could reduce net interest income. We are unable to predict changes in market interest rates which are affected by many factors beyond our control including
inflation, recession, unemployment, money supply, domestic and international events and changes in the United States and other financial markets. Net interest income is not only affected by the level and direction of interest rates, but also by the
shape of the yield curve, relationships between interest sensitive instruments and key driver rates, as well as balance sheet growth, client loan and deposit preferences and the timing of changes in these variables.

We attempt to manage risk from changes in market interest rates, in part, by controlling the mix of interest rate-sensitive assets and interest
rate-sensitive liabilities. We review our interest rate risk position and modify our strategies based on projections to minimize the impact of future interest rate changes. However, interest rate risk management techniques are not exact. A rapid
increase or decrease in interest rates could adversely affect our results of operations and financial condition.

Suffolks
Chief Executive Officer and Chief Financial Officer (collectively, the Certifying Officers) are responsible for establishing and maintaining disclosure controls and procedures for Suffolk. Based upon their evaluation of these controls
and procedures as of a date within 90 days of the filing of this report, the Certifying Officers have concluded that Suffolks disclosure controls and procedures are effective to ensure that information required to be disclosed by Suffolk in
this report is accumulated and communicated to Suffolks management, including its principal executive officers as appropriate, to allow timely decisions regarding required disclosure.

The Certifying Officers also have indicated that there were no significant changes in Suffolks internal controls or other factors that could significantly affect these controls subsequent to the
date of their evaluation, and there were no corrective actions with regard to significant deficiencies and material weaknesses. Managements Report on Internal Control over Financial Reporting is incorporated herein and can be found on page 29.
The effectiveness of Suffolks internal control over financial reporting as of December 31, 2010, has been audited by Grant Thornton LLP whose report can be found on page 56.
