Vienna, Austria, 12 December 2014 - The management board of C.A.T. oil AG (Company) (ISIN: AT0000A00Y78; WKN: A0JKWU) was informed by AB PCO Investment Limited (Cyprus) (AB PCO), an investment vehicle of the member of the management board Anna Brinkmann, on 12 December 2014 that the offer document which was published by Joma Industrial Source Corp. (Joma or Bidder) on 11 December 2014 in conjunction with its mandatory takeover offer for all shares of the Company is allegedly incorrect in two respects. On the one hand, according to AB PCO, the Bidder informed AB PCO that the shares of the Company which are held by CAT. Holding (Cyprus) Ltd. (CAT. Holding) - in contrast to the information provided in the offer document on page 24 et seq. (English language version) - have not been pledged. According to the Bidder's Cypriot lawyers' information this statement was a misunderstanding ("Furthermore for the avoidance of any misunderstanding or confusion we attach for your reference an extract […] which confirms that no security interest whatsoever or charge was or is created over the shares of CAT Oil AG held by CAT Holding (Cyprus) Ltd. No share pledge or charge of shares has been granted by […] CAT. Holding (Cyprus) Limited […].").On the other hand, according to AB PCO, the Non-Tender Agreement
- mentioned on page 25 et seq. of the offer document (English language version) - between the Bidder and CAT. Holding is null and void due to violation of statutory law. The management board will inform the competent German Federal Financial Supervisory Authority (BaFin) about this situation without undue delay together with the request to further investigate the facts and to issue appropriate orders if necessary. This Ad hoc-disclosure does not qualify as a statement, or as part of a statement, by the management board and the supervisory board within the meaning of sec. 27 of the German Securities Acquisition and Takeover Act (WpÜG), which the management board and supervisory board will publish within the statutory period.
