we effected a

one

-for-

two thousand

reverse split of our common stock by the filing of an amendment to our certificate of incorporation with the State of Delaware.

Stock Options

During the

three

months ended

March 31, 2020,

there were

transactions involving our stock option plan. As a result of the reverse stock splits enacted in

April 2019

and in

January 2020,

we have made adjustments and retroactive restatements to all of our outstanding stock options such that the balances as of

March 31, 2020

are negligible. Therefore, there was

stock-based compensation expense related to our stock option plan recognized in the consolidated statement of operations for the

three

months ended

March 31, 2020.

Stock Purchase Warrants

The following table summarizes our stock purchase warrants outstanding as of

March 31, 2020:

	Expiration Date	Exercise Price		Number of Warrants
Series G	September 2021	$	25,440		48
Series H	December 2021		1.15		217,392
Series I	Aug-Dec 2024		15,000		48

All of the outstanding warrants contain anti-dilution and price adjustment provisions, which

may,

under certain circumstances reduce the exercise price to match if we sell or grant options to purchase, including rights to reprice, our common stock or common stock equivalents at a price lower than the then exercise price of the warrants. Such provisions as to the Series G and Series H Warrants apply to the exercise price only, with

effect on the number of shares subject to the warrants. Such provisions as to the Series I Warrants apply to both the exercise price and the number of shares subject to the warrants, so that the number of warrants will be increased such that the aggregate exercise price, after taking into account the decrease in the exercise price, will be equal to the aggregate exercise price prior to the adjustment. The Series H Warrants have an additional price adjustment provision requiring a similar adjustment to the exercise price and number of warrants following a reverse stock split of our common stock; such adjustments occurred in connection with our

April 30, 2019

reverse stock split and our

January 21, 2020
