capital markets or increased cost of borrowings, including as a result of a credit rating downgrade, (11) inherent uncertainties involved in the estimates and judgments used in the preparation of financial statements and the providing of
estimates of financial measures, in accordance with the accounting principles generally accepted in the United States of America and related standards, or on an adjusted basis, (12) the integration of IFF and its Frutarom business and/or
N&Bco being more difficult, time consuming or costly than expected, (13) the failure to achieve expected or targeted future financial and operating performance and results, (14) the possibility that IFF may be unable to achieve
expected benefits, synergies and operating efficiencies in connection with the proposed transaction within the expected time frames or at all or to successfully integrate Frutarom and N&Bco, (15) customer loss and business disruption being
greater than expected following the proposed transaction, (16) the impact of divestitures required as a condition to consummation of the proposed transaction as well as other conditional commitments, (17) legislative, regulatory and
economic developments; (18) an increase or decrease in the anticipated transaction taxes (including due to any changes to tax legislation and its impact on tax rates (and the timing of the effectiveness of any such changes)) to be paid in
