Forward-Looking Statements

This communication contains forward-looking statements that
involve a number of risks and uncertainties. Words such as
believes, anticipates, plans, expects, seeks, estimates, and
similar expressions are intended to identify forward-looking
statements, but other statements that are not historical facts
may also be deemed to be forward-looking statements. Important
factors that could cause actual results to differ materially from
those indicated by forward-looking statements include risks and
uncertainties relating to: the need to develop new products and
adapt to significant technological change; implementation of
strategies for improving growth; general economic conditions and
related uncertainties; dependence on customers capital spending
policies and government funding policies; the effect of exchange
rate fluctuations on international operations; use and protection
of intellectual property; the effect of changes in governmental
regulations; and the effect of laws and regulations governing
government contracts, as well as the possibility that expected
benefits related to recent and pending acquisitions, including
the proposed transaction, may not materialize as expected; the
proposed transaction not being timely completed, if completed at
all; prior to the completion of the transaction, Patheons
business experiencing disruptions due to transaction-related
uncertainty or other factors making it more difficult to maintain
relationships with employees, customers, licensees, other
business partners or governmental entities; difficulty retaining
key employees; the outcome of any legal proceedings related to
the proposed transaction; and the parties being unable to
successfully implement integration strategies or to achieve
expected synergies and operating efficiencies within the expected
time-frames or at all. Additional important factors that could
cause actual results to differ materially from those indicated by
such forward-looking statements are set forth in Thermo Fishers
Annual Report on Form 10-K for the year ended December 31, 2016,
which is on file with the U.S. Securities and Exchange Commission

Thermo Fishers or Patheons views as of any date subsequent to
