Reverse Stock Split

Effective May 20, 2015, Lexicon completed a one-for-seven reverse split of its common stock. All references to shares of common stock and per-share data for all periods presented in this report have been adjusted to give effect to this reverse stock split. Proportional adjustments were also made to all shares of common stock issuable under Lexicon’s equity incentive plans and upon conversion of Lexicon’s Notes.  Concurrent with the reverse stock split, the authorized shares of common stock were reduced from 900 million (prior to the reverse stock split) to 225 million.  As no change was made to the par value of the common shares, common stock and additional paid-in capital were adjusted on a retroactive basis to give effect to the reverse stock split. No fractional shares were issued in connection with the reverse stock split.  Any fractional share of common stock that would otherwise have resulted from the reverse stock split were converted into cash payments equal to such fraction multiplied by the closing sales price of the common stock as last reported on the last trading day immediately preceding the effective date of the reverse stock split.
