Proposal 3 — Advisory Vote on Executive Compensation: To approve, in a non-binding, advisory vote, the compensation paid to our named executive officers.

The stockholders approved, on an advisory, non-binding basis, the compensation of our named executive officers. The final results of the voting for this proposal are set forth below:

Proposal 4 — Frequency of Advisory Vote on Executive Compensation: To determine, in a non-binding, advisory vote, whether a stockholder vote to approve the compensation paid to our named executive officers should occur every one, two or three years.

The stockholders voted for one year with respect to the frequency with which stockholders are provided a non-binding, advisory vote on the compensation paid to our named executive officers. The final results of the voting for this proposal are set forth below:

As described above, a majority of the votes cast voted, in an advisory, non-binding vote, in favor of having a stockholder vote to approve the compensation of the Company’s named executive officers every year. In light of such vote, and consistent with the Company’s recommendation, the Company’s board of directors determined that it currently intends to include an advisory, non-binding vote to approve the compensation of the Company’s named executive officers every year until the next required vote on the frequency of stockholder votes on the compensation of the Company’s named executive officers.
