Capitalized terms used herein without definition shall have the respective meanings ascribed to them in the Agreement. The Shares will be issued in an underwritten public offering pursuant to the Company’s Registration Statement on Form S-3 (Registration No. 333-189191), as amended, filed by the Company with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), and the related prospectus dated August 2, 2013 and prospectus supplement dated the date hereof (collectively, the “Prospectus”).
