Warrant Inducement Agreement

On December 7, 2023, Altamira Therapeutics Ltd., an exempted company limited by shares incorporated in Bermuda (the "Company") entered into a letter agreement (the "Warrant Inducement Agreement") with the holder (the "Holder") of certain warrants (the "Existing Warrants") to purchase an aggregate of 1,625,487 of the Company's common shares, par value $0.0001 per share (the "Common Shares") dated May 1, 2023 in order to provide the Holder with a limited opportunity to exercise such Existing Warrants at a reduced exercise price and receive additional warrants upon any such exercise.

Under the Warrant Inducement Agreement, effective from the date and time of execution thereof until 12:59 PM ET on December 14, 2023 (such period, the "Exercise Window"), the Existing Warrants are temporarily amended by reducing the Exercise Price (as defined therein; currently CHF 1.538 per common share) of the Existing Warrants from time to time during such period to an amount with respect to each exercise of Existing Warrants during such Exercise Window (the "Reduced Exercise Price") equal to 90% of the daily trading volume weighted average price for Common Shares on the NASDAQ stock exchange on the trading day following the date of each such exercise upon which settlement of such exercise occurs (a "Settlement Day") measured commencing at the time of such settlement, in each case converted into Swiss Francs at the midpoint of the interbank exchange rate shown by UBS on such Settlement Day at 4:00 pm Central European Time per Common Share (the "Warrant Amendment"). Following the end of the Exercise Window, the Exercise Price will revert to its original amount in effect immediately prior to the execution of the Warrant Inducement Agreement.

In addition, within three trading days after the end of the Exercise Window, the Company will issue and deliver to the Holder additional warrants using the same form as the Existing Warrants (the "New Warrants") to purchase 2 Common Shares for each Common Share that the Holder receives upon any exercises for cash of Existing Warrants during the Exercise Window, provided that the initial exercise price of such New Warrants will be the volume weighted average of the Reduced Exercise Prices paid by the Holder upon such exercises, if any, and equal portions (i.e. two portions of 50% each) of such New Warrants will be exercisable for (A) six months from their date of issuance and (B) two years from their date of issuance, respectively.

The Company also agreed to file a registration statement to register for resale the Common Shares issuable upon exercise of the New Warrants within 15 calendar days after the end of the Exercise Window.

The foregoing description of the terms of the Warrant Inducement Agreement is qualified in its entirety by reference to the full text of the Warrant Inducement Agreement, which is filed as Exhibit 10.1 to this Report on Form 6-K and incorporated by reference herein.

The Common Shares issuable upon exercise of the Existing Warrants were registered for resale under the registration statement on Form F-3 (No. 333-272338), filed on June 1, 2023 and declared effective on June 9, 2023.
