Each of the reporting persons (other than the direct holder) disclaims beneficial ownership of these securities, except to the extent of its or his pecuniary interest therein, and this Form shall not be construed as an admission that any such reporting person is the beneficial owner of any such securities.
Because of their relationships with the other reporting persons, each of Access Industries Holdings LLC, Access Industries, LLC and Access Industries Management, LLC may be deemed to beneficially own the ordinary shares held directly by AI Altep Investments LLC (formerly AI New Holdings LLC) and AI Chemical Holdings LLC (formerly, AI New Holdings 2 LLC) ("AICH").

The securities reported are held directly by AICH and may be deemed to be indirectly beneficially owned by Access Industries Management, LLC, Access Industries Holdings LLC and Len Blavatnik because Mr. Blavatnik controls Access Industries Management, LLC, Access Industries Holdings LLC owns a majority of the outstanding voting interests in RSB 2 Limited which is the sole member of AICH, and Access Industries Management, LLC controls AICH and Access Industries Holdings LLC.
