The names of the persons filing this statement are:

Marius Skaugen
Haut Brion AS (collectively, the “Filers”)

The Filers are filing this Schedule 13G jointly but not as members of a group, and each disclaims membership in a group. Each of the Filers disclaims beneficial ownership of the Stock (as defined in section (d) below), except to the extent of that person’s pecuniary interest therein.

Prior to October 18, 2021, Mr. Skaugen was included as a joint filer on a Schedule 13G filed by Arvarius AS to report beneficial ownership of Stock of the Issuer. On October 18, 2021, Arvarius AS distributed all Stock of the Issuer held by it to its investors, including Haut Brion AS, for no consideration. As a result, Arvarius AS filed an amendment to its Schedule 13G to report that it is no longer a beneficial owner of the Issuer’s Stock, and Mr. Skaugen and Haut Brion AS are separately filing this Schedule 13G to report their beneficial ownership of the Issuer’s Stock.

On October 18, 2021, the Filers acquired 4,421,974 shares of the Stock, representing 7.8% of the outstanding Stock. The Filers subsequently disposed of shares of the Stock and have ceased to own more than 5% of the Stock. In addition, Haut Brion has distributed its remaining shares of the Stock to its investors, including Mr. Skaugen. This Schedule 13G reports the Filers’ ownership of the Stock as of the date of filing.

(b)

The principal business office of the Filers is located at:

Parkveien 57
c/o B. Skaugen
Oslo Q8 AS 0256

(c)

For citizenship of Filers, see Item 4 of the cover sheet for each Filer.
