Preferred Stock Rights

On May 23, 2013, the Company's Board of Directors adopted a tax benefit preservation plan in the form of a Section 382 Rights Agreement (the 382 Agreement). The 382 Agreement is intended to diminish the risk that our ability to use our net operating loss carryforwards to reduce future federal income tax obligations may become substantially limited due to an “ownership change,” as defined in Section 382 of the Internal Revenue Code. The Board authorized and declared a dividend distribution of one right for each outstanding share of common stock, par value $0.0001 per share, of the Company to stockholders of record as of the close of business on June 4, 2013. Each right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series B Participating Preferred Stock, par value $0.0001 per share, of the Company at an exercise price of $20.00 per one one-thousandth of a Preferred Share, subject to adjustment.

The rights will become exercisable following (i) the 10th business day (or such later date as may be determined by the Board of Directors) after the public announcement that an acquiring person has acquired beneficial ownership of 4.99% or more of the common shares of the Company or (ii) the 10th business day (or such later date as may be determined by the Board of Directors) after a person or group announces a tender or exchange offer that would result in ownership by a person or group of 4.99% or more of the common shares of the Company.

In addition, upon the occurrence of certain events, the exercise price of the rights would be adjusted and holders of the rights (other than rights owned by an acquiring person or group) would be entitled to purchase common stock at approximately half of market value. Given the potential adjustment of the exercise price of the rights, the rights could cause substantial dilution to a person or group that acquires 4.99% or more of the Company's common stock on terms not approved by the Company's Board of Directors.

No rights were exercisable at December 31, 2014. There is no impact to the Company's financial results as a result of the adoption of the rights plan for the years ended December 31, 2014 and 2013.
