INFORMATION REQUIRED IN
THE REGISTRATION STATEMENT
Item 3. Incorporation of Documents by Reference.
The following documents are incorporated herein by reference:
(a) The Registrant's Annual Report on Form 20-F filed with the
Commission on March 18, 2021 (Registration No. 001-39071), which contains the Registrant's audited financial statements for the
latest fiscal year for which such statements have been filed.
(b) The Registrant's Report of Foreign Private Issuer on Form
6-K filed with the Commission on May 6, 2021 (other than Exhibit 99.3 thereto) (Registration No. 001-39071).

contained in the Registrant's Registration Statement Form 8-A (Registration No. 001-39071), dated May 11, 2020, including any amendments
or supplements thereto.
In addition, all documents subsequently filed by the Registrant with
the Commission pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended (the "
Exchange
Act
"), prior to the filing of a post-effective amendment to this Registration Statement which indicates that all securities
offered have been sold or which deregisters all securities then remaining unsold, including any Reports of Foreign Private Issuers on
Form 6-K submitted during such period (or portion thereof) that is identified in such form as being incorporated by reference into this
Registration Statement, shall be deemed to be incorporated by reference in this Registration Statement and to be a part hereof from the
date of the filing of such documents. The Registrant is not incorporating by reference any documents or portions thereof, whether specifically
listed above or filed in the future, that are not deemed "filed" with the Commission.
Any statement contained in a document incorporated or deemed to be
incorporated by reference herein shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent
that a statement contained herein, (or in any other subsequently filed document which also is incorporated or deemed to be incorporated
by reference herein), modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except
as so modified or superseded, to constitute a part of this Registration Statement.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
Under Swiss law, a corporation may indemnify its
directors or officers against losses and expenses (except for such losses and expenses arising from willful misconduct or negligence,
although legal scholars advocate that at least gross negligence be required), including attorney's fees, judgments, fines and settlement
amounts actually and reasonably
incurred in a civil or criminal action, suit or
proceeding by reason of having been the representative of, or serving at the request of, the corporation.
Subject to Swiss law, the Registrant's amended
and restated articles of association provides for indemnification of the existing and former members of the Registrant's board of
directors, executive committee as well as their heirs, executors and administrators, against liabilities arising in connection with the
performance of their duties in such capacity, and the Registrant's amended and restated articles of association requires the Registrant
to advance the expenses of defending any act, suit or proceeding to existing and former members of the Registrant's board of directors
and executive committee to the extent not included in insurance coverage or advanced by third parties.
In addition, under general principles of Swiss
employment law, an employer may be required to indemnify an employee against losses and expenses incurred by such employee in the proper
execution of their duties under the employment agreement with the company.
The Registrant has entered into indemnification
agreements with each of the members of its board of directors and executive committee. The indemnification agreements and our articles
of association require us to indemnify our executive officers and directors to the fullest extent permitted by law.
Insofar as indemnification for liabilities arising
under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant, the Registrant has been advised
that, in the opinion of the Commission, such indemnification is against public policy as expressed in the Securities Act and is, therefore,
unenforceable.
