The purchase agreements provide certain registration rights, pursuant to which the Company has agreed to file a registration statement within 30 business days to register the resale of the common shares sold in the private placement and the common shares issuable upon exercise of the pre-funded warrants sold in the private placement.

The private placement is exempt from the registration requirements of the Securities Act under Section 4(a)(2) of the Securities Act in that the private placement is between an issuer and sophisticated investors not involving any public offering. The Company is relying on this exemption from registration based in part on representations made in the purchase agreements for the private placement, a form of which is attached to this Current Report on Form 8-K as Exhibit 10.1.

The pre-funded warrants are exercisable at any time after their original issuance until the tenth anniversary of their original issuance. At any time during the last 90 days of the term, the holder may exchange the pre-funded warrant for, and the Company will issue, a new pre-funded warrant for the number of common shares then remaining under the pre-funded warrant. The pre-funded warrants will be exercisable, at the option of each holder, in whole or in part (but not for less than a common share) by delivering to the Company a duly executed exercise notice and by payment of the aggregate exercise price; provided that any exercise of the pre-funded warrants must be for at least 50,000 common shares (or, if less, the remaining common shares available for purchase under the pre-funded warrants). A holder will not be entitled to exercise any portion of any pre-funded warrants that, upon giving effect to such exercise, would cause the aggregate number of the Company’s common shares beneficially owned by the holder (together with its affiliates and certain attribution parties) to exceed 9.99% (or, 61 days after a written notice from such holder, any other percentage not in excess of 19.99%) of the number of the Company’s common shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants. The exercise price per common share purchasable upon the exercise of the pre-funded warrants is CHF 0.08 per share, subject to customary adjustments. In lieu of making cash payment of the aggregate exercise price, a holder may elect to exercise the pre-funded warrants on a cashless basis. However, if the Company, at the time of receipt of an exercise notice electing cashless exercise, (i) does not, or has reason to believe that the Company does not, have a sufficient amount of freely distributable equity to fund the nominal value of the number of common shares the Company would be required to deliver upon such cashless exercise, and (ii) (x) holds common shares representing more than 2% of its share capital registered in the commercial register at that time (the "Minimum Stock") in treasury, then the Company will not be obligated to (but may) deliver more than such number of common shares to the holder as exceeds the Minimum Stock or (y) holds up to the Minimum Stock in treasury, then the Company will not be obligated to deliver any common shares to the holder. The exercise notice will be deemed to be null and void to the extent the holder receives fewer common shares than to which such exercise notice relates. In the event of (i) a sale, lease or other transfer of all or substantially all of the Company’s assets, (ii) a merger or consolidation involving the Company in which the Company is not the surviving entity or in which the Company’s outstanding share capital is converted into or exchanged for shares of capital stock or other securities or property of another entity, or (iii) any sale by holders of the Company’s outstanding voting equity securities in a single transaction or series of related transactions of shares constituting a majority of the Company’s outstanding combined voting power, and (x) if the consideration received by the Company’s shareholders consists solely of cash and/or marketable securities, then holders of the pre-funded warrants will be deemed to have exercised their pre-funded warrants (without regard to the exercise limitations described above) immediately prior to the closing date of such transaction or (y) if the consideration received by the Company’s shareholders does not consist solely of cash and/or marketable securities, then the Company will cause the successor or surviving entity to assume the pre-funded warrants. Subject to applicable laws, the pre-funded warrants may be offered for sale, sold, transferred or assigned without the Company’s consent. The pre-funded warrants are governed by the laws of Switzerland. The foregoing description of the pre-funded warrants does not purport to be complete and is qualified in its entirety by reference to the form of pre-funded warrant, which is attached to this Current Report on Form 8-K as Exhibit 10.2.
