ANNEX A

AMENDMENT TO SELLING SECURITYHOLDER INFORMATION

 

This Prospectus Supplement No. 1 is being filed in connection with certain changes to the selling securityholder information as set forth in the Prospectus dated November 25, 2016 (as supplemented to date, the “Prospectus”) resulting from the transfer by Tungsten III, LLC (“Tungsten”), an entity controlled by Michael A. Parker, of its Series D Warrants to Ana B. Parker, Mr. Parker’s wife. Consequently, the selling securityholders table (the “Selling Securityholders Table”) appearing under the heading “SELLING SECURITYHOLDERS” in the Prospectus is hereby amended and supplemented by (i) deleting the information for Tungsten in the Selling Securityholders Table; (ii) adding the following information for Ms. Parker to the Selling Securityholders Table; and (iii) updating footnotes (1) through (5):

 

Column 1 Column 2 Column 3 Column 4 Column 5 Column 6
Name of Selling Securityholder Number of Shares of Common Stock Issued and Issuable (1) Number of Shares of Common Stock Beneficially Owned Prior to this Offering (2) Maximum Number of Shares of Common Stock to be Sold Pursuant to this Prospectus (3) Number of Shares of Common Stock Beneficially Owned After This Offering (4) Percentage of Shares of Common Stock Beneficially Owned After This Offering (5)
Ana B Parker (24) 12,348,932 4,434,829 4,500,000 4,434,829 4.92%

 

(1)Reflects the total number of shares of Common Stock held or issuable to each selling securityholder including, to the extent applicable, (a) all remaining securities issued in the 2015 Private Placement Financing, in each case without regard to ownership limitations on the exercise of certain of the Series D Warrants as described in footnote (2) below; (b) all remaining securities issued in the 2016 Private Placement Financing (and together with the 2015 Private Placement Financing, the “Private Placement Financings”), none of which are being registered in the 2016 S-3 Registration Statement of which this prospectus forms a part and in each case without regard to the ownership limitations on the exercise of certain of the Series E Warrants as described in footnote (2) below; (c) all remaining securities issued in connection with the registered direct offering that closed on July 2, 2018 (the “2018 Financing”), none of which are being registered in the 2016 S-3 Registration Statement of which this prospectus forms a part and in each case without regard to the ownership limitations on the exercise of the Series G Warrants as described in footnote (2) below; (d) all remaining securities issued in connection with the registered direct offering that closed on May 14, 2019 (the “2019 Financing”, and together with the Private Placement Financings and 2018 Financing, the “Equity Financings”), none of which are being registered in the 2016 S-3 Registration Statement of which this prospectus forms a part and in each case without regard to the ownership limitations on the exercise of the Series H Warrants as described in footnote (2) below; and (e) all other securities issued in transactions unrelated to the Equity Financings, if any, none of which are being registered in the 2016 S-3 Registration Statement of which this prospectus forms a part and in each case without regard to any ownership limitations upon the exercise or conversion of such securities.

 

(2)Certain of the Series E and Series D Warrants issued in the 2016 Private Placement Financing and 2015 Private Placement Financing, respectively and all the Series G Warrants and Series H Warrants issued in the 2018 Financing and 2019 Financing, respectively, contain ownership limitations to prevent the exercise of such warrants in certain circumstances. In particular, certain of the Series E Warrants provide that they shall not be exercisable in the event and to the extent that the exercise thereof would result in the holder of the Series E Warrant, together with its affiliates and any other persons whose beneficial ownership of Common Stock would be aggregated with the holder’s, would be deemed to beneficially own more than 4.99% of the Common Stock; provided, however, the (i) holder, upon notice to us, may increase or decrease this ownership limitation so long as the maximum ownership limitation does not exceed 9.99% of the Company’s Common Stock; and (ii) any increase in the ownership limitation will not become effective until the 61st day after delivery of such notice. Similarly, certain of the Series D Warrants provide that a selling securityholder may not exercise such warrants to the extent (but only to the extent) that the exercise thereof would result in the selling securityholder or any of its affiliates beneficially owning more than 4.9% of our Common Stock after giving effect to such exercise; provided, however, that in the case of any Series D Warrant with an ownership limitation, the holder may waive such ownership limitation, in which case such waiver will become effective sixty-one (61) days after the holder’s delivery of such wavier notice. Finally, the Series G Warrants and Series H Warrants provide that they may not be exercised if the holder, together with its affiliates and any other persons whose beneficial ownership of the Common Stock would be aggregated with the holder’s, would be deemed to beneficially own more than 4.99% of the Common Stock; provided, however, the (i) holder, upon notice to us, may increase this ownership limitation so long as the maximum ownership limitation does not exceed 9.99% of the Company’s Common Stock; and (ii) any increase in the ownership limitation will not become effective until the 61st day after delivery of such notice.
