The following votes were cast at the Special Meeting (in person or by proxy) on the Merger Proposal:

The Merger Proposal was approved by the holders of more than a majority of Catalyst's outstanding common shares, which satisfies one of the closing conditions under the Merger Agreement for consummation of the Merger.

To approve, on a non-binding, advisory basis, the compensation that may be paid or become payable to Catalyst's named executive officers that is based on or otherwise relates to the Merger and/or the other transactions contemplated by the Merger Agreement.

The following votes were cast at the Special Meeting (in person or by proxy) on the Compensation Proposal:

The Compensation Proposal was not approved by the requisite vote of Catalyst stockholders required to approve such proposal. However, approval of the Compensation Proposal is advisory and non-binding and is not a condition to the completion of the Merger.

The proposal to adjourn the Special Meeting to a later date or dates as provided in the Merger Agreement, if necessary or appropriate, to solicit additional votes if there are insufficient votes to adopt the Merger Agreement at the time of the Special Meeting, was not voted upon at the Special Meeting since there were sufficient votes to approve the Merger Proposal.
