[IFF LETTERHEAD] Exhibit 10 (o) As of October 1, 1999 Mr. Carlos A. Lobbosco Thorney Court Apartments Palace Gate Kensington London W8 5NJ England Dear Carlos, This letter will outline the understandings you and International Flavors & Fragrances Inc. ("IFF" or the "Company") have reached in respect of your assignment, effective October 1, 1999, as President, Fragrance Division (the "Assignment"). This letter supersedes the letter agreement between you and IFF dated June 23, 1998. We have agreed as follows: 1. Effective October 1, 1999, your annual base salary will be US$500,000. Your salary will be reviewed annually, commencing at the end of 2000, in accordance with IFF policy for officers of the Company. 2. IFF will cause to be leased for your use during the Assignment, in the name of IFF, an apartment in New York City, New York, for your business and personal use (the "Apartment"). IFF will cause the rent and utilities (other than telephone) to be paid on the Apartment. The initial monthly rent for the Apartment may not exceed US$10,000 without the prior written approval of the Chairman and Chief Executive Officer of the Company. Any taxable income that you are required to recognize as a result of the Company's leasing the Apartment for your use will be considered "Other Assignment Income", as defined in Mr. Carlos A. Lobbosco As of October 1, 1999 Page 2 of 7 Pages Section 5 below. You will be responsible for all costs related to any housing that you continue to maintain in Argentina during the Assignment. 3. During the Assignment you will continue to participate in the IFF Management Incentive Compensation Plan ("MICP") on the same terms as you currently participate in the MICP. Your MICP award will continue to be based on a combination of the performance of IFF as well as your own performance. 4. I will recommend to the Stock Option and Compensation Committee of the Board of Directors that, at its meeting on November 9, 1999, you be granted a stock option award of 25,000 shares of IFF Common Stock under, and subject to the terms and conditions of, the IFF 1997 Employee Stock Option Plan. 5. To the extent that the effective aggregate income tax rate on your annual base salary and MICP during the relating to the Assignment ("Assignment Salary and Bonus") exceeds 30%, IFF will reimburse you, on a fully "grossed up" basis, for all income taxes in excess of 30% in respect of such taxable Assignment Salary and Bonus. IFF will also fully "gross up" any other taxable income relating to the Assignment that you are required to recognize ("Other Assignment Income"). Assignment Salary and Bonus and Other Assignment Income are sometimes collectively referred to as "Assignment Compensation." The effective aggregate income tax rate on your Assignment Salary and Bonus, and the income tax due on Other Assignment Income, will be determined by considering income taxes owed on the Assignment Salary and Bonus and Other Assignment Income in any country in which such taxes are required to be paid, and will be calculated by PricewaterhouseCoopers LLP or such other independent public accountants whom IFF may elect to retain to prepare your income tax returns related to the Assignment Compensation (the "Accountant"). IFF will pay that percentage of the cost of having your taxes prepared by the Accountant that Assignment Compensation bears to total taxable income reported in returns prepared for you by the Accountant (the "Assignment Compensation Percentage"). The Mr. Carlos A. Lobbosco As of October 1, 1999 Page 3 of 7 Pages determination by the Accountant of (a) the effective aggregate income tax rate in respect of Assignment Salary and Bonus, (b) income taxes owed on Other Assignment Income, and (c) the Assignment Compensation Percentage will be binding on both you and IFF. You will be fully and solely responsible for all income and other taxes due in any country in respect of any income (whether or not compensation from IFF) other than Assignment Compensation. Any taxable income that you are required to recognize as a result of the Company's payment of the Assignment Compensation Percentage will be considered Other Assignment Income. 6. During the Assignment you will continue to participate in the IFF TCN Pension Plan, (the "TCN Plan"). IFF agrees to assure that, upon your retirement from the Company, you will receive an aggregate minimum monthly pension, expressed as a 60-month annuity certain (the "Pension"), of at least the amount in respect of the various retirement dates set forth in the schedule below (the "Pension Schedule"). The Pension will be paid in US Dollars. If your actual retirement date (the "Retirement Date") falls between any two dates in the Pension Schedule, the Pension will be adjusted accordingly. The amount of the Pension will first be calculated by aggregating the retirement benefits that you have or will have earned at your actual retirement date from all sources in which you currently participate or have participated during your IFF service, including but not limited to the TCN Plan, pension plans of other IFF entities, and the Argentina social security/retirement system (collectively the "Applicable Sources"). The amount of the Pension will be calculated in accordance with the terms of the TCN Plan. If for any reason the Pension as calculated under the TCN Plan does not provide the minimum Pension required by the Pension Schedule, IFF will pay you a monthly supplemental amount so that your aggregate retirement benefit from all Applicable Sources equals the Pension required by the Pension Schedule for the applicable retirement date. You will have the right to elect to receive the Pension Mr. Carlos A. Lobbosco As of October 1, 1999 Page 4 of 7 Pages in such a way that, rather than receiving a 60-month annuity certain (which provides no benefit for your surviving spouse beyond the fifth anniversary after the Retirement Date), your surviving spouse, upon your death, will continue to receive a benefit equal to 50% of the benefit you were receiving at your death. You acknowledge, however, that should you elect such a "joint and 50%" option, the amount to be paid to you at your retirement will be reduced actuarially from that set forth in the Pension Schedule.

IFF will pay for up to eight round trip business class airfares between Argentina and New York, which may be used by you and members of your family.

In such event, you may elect (a) to commence receiving the Pension immediately after the Retirement Date, or (b) in lieu of commencing to receive the Pension at the Retirement Date, to receive "Salary Continuation Payments" equal to your monthly base salary at the Retirement Date, for the shorter of (i) twenty-four (24) months or (ii) if the Retirement Date occurs on or after July 1, 2001, the number of months between the Retirement Date and July 1, 2003, after which the Pension will commence (with the amount of the Pension--including the guaranteed minimum--computed based on your years of service through the Retirement Date but with a commencement date based on your age on the actual date on which the Pension commences).
