On January 8, 2018, the Company announced a reverse split of its common stock, $0.001 par value, at a ratio of 1 for 10, which became effective January 19, 2018 (the “Effective Date”). The Company’s common stock began trading on a split-adjusted basis on January 22, 2018 under the existing trading symbol “OGEN”.

As a result of the reverse split, each 10 pre-split shares of common stock outstanding were automatically combined into one new share of common stock without any action on the part of the holders, and the number of outstanding common shares was reduced from approximately 49 million shares to approximately 4.9 million shares. The reverse split also applied to common stock issuable upon the exercise of the Company’s outstanding stock options. In addition, the Company also announced that the authorized common stock of the Company was decreased from 450 million to 45 million shares. The authorized preferred stock remains at 50,000,000 shares. The common stock issued pursuant to the reverse stock split will remain fully paid and non-assessable. The reverse stock split did not affect the par value of the common stock.

The majority shareholders approved giving the Board discretionary authority to enact the reverse stock split by written consent on December 1, 2017 in accordance with the Company’s current articles of incorporation and bylaws. The Board approved the reverse stock split on a one for ten ratio on January 8, 2018.

No fractional shares were issued as a result of the reverse stock split. Shareholders who otherwise would be entitled to a fractional share because they hold a number of shares not evenly divisible by the 1 for 10 reverse split ratio, were automatically entitled to receive an additional fractional share of the Company’s common stock to round up to the next whole share.
