Employee Stock Purchase Plan

The Company's Employee Stock Purchase Plan, as amended and restated (the "Amended ESPP") allows participants to purchase up to 1,250 shares of Ligand common stock during each offering period, but in no event may a participant purchase more than 1,250 shares of common stock during any calendar year. The length of each offering period is six months, and employees are eligible to participate in the first offering period beginning after their hire date.

The Amended ESPP allows employees to purchase Ligand common stock at the end of each six month period at a price equal to 85% of the lesser of fair market value on either the start date of the period or the last trading day of the period (the "Lookback Provision"). The 15% discount and the Lookback Provision make the Amended ESPP compensatory. There were 2,404 and 81,844 shares of common stock issued and $18,000 and $0.1 million of proceeds received under the Amended ESPP during the six months ended June 30, 2011 and 2010, respectively. The Company recorded compensation expense of $700 and $44,000 for the six months ended June 30, 2011 and 2010, respectively. As of June 30, 2011, 102,498 shares were available for future purchases under the Amended ESPP.

Warrants

As of June 30, 2011, warrants to purchase 144,606 shares of the Company's common stock were outstanding with an exercise price of $51.54 per share and an expiration date of April 2012. The warrants were assumed in the acquisition of Pharmacopeia, Inc.

As of June 30, 2011, 163,568 warrants with an exercise price of $179.40 per warrant and an expiration date of April 2013 were outstanding to purchase an aggregate of 129,360 shares of the Company's common stock. If exercised, these warrants are also entitled to receive $0.1 million in cash and 981,411 of each of the Company's four contingent value rights issued to Neurogen shareholders in December 2009. The series of warrants was assumed in the acquisition of Neurogen Corporation.
