Details regarding the voting results in respect of the election of directors of the Company are set forth below.

Election of Directors

The election of each of the following director nominees proposed by management was duly authorized and approved by Shareholders, as follows:

Five of the director nominees previously served on the board of directors of Rock Tech, while Ms. Dönges and Ms. Gahagan were nominated for the first time. Ms. Dönges is a member of the executive board of the Federal Republic of Germany Finance Agency and a non-executive member of the supervisory board of Commerzbank AG, a significant entity supervised by the European Central Bank and the national competent authority. In order to act as a director of Rock Tech, Ms. Dönges requires the approval of these supervisory authorities (the "Regulatory Approval"). As at the date hereof, Ms. Dönges has applied for but not yet received the Regulatory Approval.

Ms. Dönges has agreed to deliver her formal consent to act as a director of the Company in accordance with the Business Corporations Act (British Columbia) subject to and following her receipt of the Regulatory Approval. Accordingly, while Ms. Dönges' election as a director of the Company has been authorized by Shareholders, she is not currently a director of the Company and, until the Regulatory Approval is granted and the Company has received Ms. Dönges' consent, she will not act as a director of the Company.

Following Ms. Dönges' becoming a director of the Company, she will hold office until Rock Tech's next annual meeting of Shareholders or until her successor is duly elected or appointed. The election of each of the other director nominees was effective as of the close of the Meeting, and such persons will hold office until Rock Tech's next annual meeting of Shareholders or until their successor is duly elected or appointed.
