                         Community Bank System Completes
                      Tupper Lake National Bank Acquisition

      Syracuse, N.Y. - June 4, 2007 - Community Bank System, Inc. (NYSE: CBU)
has completed its acquisition of TLNB Financial Corporation, as previously
announced in January.

      Based in Tupper Lake, N.Y., TLNB Financial Corporation is the parent of
Tupper Lake National Bank, which operates five branches, including two in the
Clinton County city of Plattsburgh, one in the Essex County village of Saranac
Lake, and two in its Franklin County base of Tupper Lake. All branches have been
re-branded as "Community Bank, N.A." facilities, and have begun operating as
such beginning today. It also operates an insurance agency subsidiary, TLNB
Insurance Agency, Inc., with offices in Tupper Lake and Plattsburgh, which has
also been renamed as "CBNA Insurance Agency, Inc."

      An all-cash transaction valued at approximately $17.6 million, this
acquisition is expected to have an accretive impact on earnings in 2008. As of
March 31, 2007, Tupper Lake National Bank held approximately $100 million in
assets, including $56 million of loans, and $87 million in customer deposits.

      "We enthusiastically welcome Tupper Lake National's customers and
employees into the Community Bank, N.A. family," said Mark E. Tryniski,
President and Chief Executive Officer of Community Bank System. "This
transaction represents a very attractive expansion opportunity for us. Its
Plattsburgh and Saranac Lake locations will mark our first entry into the
counties of Clinton and Essex, respectively. It is a very logical extension of
our northern New York footprint into markets that we've been looking to expand
into for some time. In addition, it's an opportunity to strengthen our presence
in Franklin County to a `number-one' market share position. We're confident that
the greater breadth of banking and financial services products which we offer
will be well received by consumers within these markets. "

      Community Bank System, Inc. (NYSE: CBU) is a registered bank holding
company based in DeWitt, N.Y., with approximately $4.5 billion in assets and
more than 130 customer facilities. Its wholly-owned banking subsidiary operates
as Community Bank, N.A. across Upstate New York, and as First Liberty Bank &
Trust throughout Northeastern Pennsylvania. Its other subsidiaries include:
BPA-Harbridge, which provides actuarial, administration, consulting and daily
valuation recordkeeping services for benefit plans from offices in Upstate New
York, Pittsburgh, PA, and Houston, TX; Community Investment Services, Inc., a
broker-dealer delivering financial products throughout the company's




branch network; and Nottingham Advisors, a wealth management and advisory firm
with offices in Buffalo, N.Y., and North Palm Beach, Fla. For more information
