“Common Stock” means the common stock of the Corporation, par value $0.001 per share.

“Common Stock Equivalent” means any securities of the Corporation that entitles the holder thereof to acquire at any time shares of Common Stock, including, without limitation, any debt, preferred stock, right, option, warrant or other instrument that is at any time convertible into or exercisable or exchangeable for, or otherwise entitles the holder thereof to receive, shares of Common Stock.

In order to exercise the alternate conversion rights provided by this Section 3 with respect to a particular Subsequent Equity Financing, the Holder shall be required surrender to the Corporation this Special Warrant Certificate with the annexed Notice of Conversion Form duly completed and executed, on or before 5:00PM Pacific Time on the 1 month anniversary of the closing date of such Subsequent Equity Financing. Failure to deliver such documents to the Corporation by the date and time set forth in this Section 3(b) shall result in the alternate conversion rights set forth in this Section 3 ceasing to be available with respect to such Subsequent Financing.

The Holder expressly agrees that any Common Stock and Common Stock Equivalents received as a result of exercising the alternate conversion rights provided by this Section 3 shall be subject to substantially the same terms and conditions as if the Holder had directly subscribed for or otherwise directly participated in such Subsequent Equity Financing, including any restrictions, covenants, conditions, qualifications, adjustments, agreements or other provisions set out in the transaction documents to such Subsequent Equity Financing (including the terms and conditions of any Common Stock Equivalents issued as a part thereof), and the Holder agrees to execute such additional documents or agreements as may reasonably be required to evidence its agreement thereto. Notwithstanding the generality of the forgoing, any restrictions on transfer or resale required under applicable securities laws as set out in the transaction documents to such Subsequent Equity Financing (including the calculation of any hold periods required under applicable securities laws) shall be determined as such laws apply to the Holder.

If and whenever the shares of Common Stock at any time outstanding shall be subdivided into a greater, or consolidated into a lesser, number of shares, the number of Units to which the Holder is entitled upon a conversion of the Special Warrants represented hereby for Units shall be decreased or increased proportionately as the case may be.

In case of any capital reorganization or of any reclassification of the capital of the Corporation or in case of the consolidation, merger or amalgamation of the Corporation with or into any other company, the Special Warrants represented hereby shall, after such capital reorganization, reclassification of capital, consolidation, merger or amalgamation, confer the right to receive:

the number of shares or other securities of the Corporation or of the Corporation resulting from such capital reorganization, reclassification, consolidation, merger or amalgamation, as the case may be, to which the Holder would have been entitled had such Holder exercised its right to convert the Special Warrants represented hereby for Units immediately prior to such capital reorganization, reclassification of capital, consolidation, merger or amalgamation; and

the number of share purchase warrants or other securities or rights conferring the Holder the right to purchase from the Corporation that number of shares or other securities of the Corporation or of the Corporation resulting from such capital reorganization, reclassification, consolidation, merger or amalgamation, as the case may be, that the Holder would have been entitled to purchase had such Holder exercised its right to convert the Special Warrants represented hereby for Units immediately prior to such capital reorganization, reclassification of capital, consolidation, merger or amalgamation.

For greater clarity, it is the intention of the Holder and the Corporation that, on such capital reorganization, reclassification, consolidation, merger or amalgamation appropriate adjustments shall be made in the application of the provisions set forth herein with respect to the rights and interest thereafter of the Holder of the Special Warrants represented hereby so that the provisions set forth herein shall thereafter be applicable as nearly as may reasonably be in relation to any shares or other securities thereafter deliverable on the conversion of the Special Warrants represented hereby.

In the event of any dispute as to the adjustments to be made as a result of the provisions of this Section 8, a determination of the board of directors of the Corporation, acting reasonably and in good faith, as to the appropriate adjustments to be made with respect thereto shall be deemed final and binding on the Corporation and the Holder.

The adjustments provided for in this Section 8 are cumulative.
