Sales Agreement Summary

The following is a summary of the Sales Agreement. This summary is not complete and is qualified in its entirety by reference to the full text of the Sales Agreement, a copy of which is filed herewith as Exhibit 1.1.

In accordance with the terms of the Sales Agreement, upon delivery of a placement notice and subject to the terms and conditions of the Sales Agreement, JonesTrading may sell the Shares by any method deemed to be an “at the market offering” as defined in Rule 415 promulgated under the Securities Act of 1933, as amended (the “Securities Act”), including sales made through the Nasdaq Global Market, on any other existing trading market for the Common Stock or to or through a market maker. In addition, with the Company’s prior written approval, JonesTrading may also sell the Shares in privately negotiated transactions.

JonesTrading will use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of the Nasdaq Global Market to sell on the Company’s behalf all of the shares requested to be sold by the Company.

The Company has no obligation to sell any of the Shares under the Sales Agreement. Either the Company or JonesTrading may at any time suspend solicitations and offers under the Sales Agreement upon notice to the other party.

The aggregate compensation payable to JonesTrading shall be equal to 3% of the gross proceeds from sales of the Shares sold by JonesTrading pursuant to the Sales Agreement. In addition, the Company has agreed to reimburse a portion of the expenses of JonesTrading in connection with the offering up to a maximum of $30,000.

The Sales Agreement contains customary representations and warranties, covenants of each party, and conditions to the sale of any Shares by JonesTrading thereunder. Additionally, each party has agreed in the Sales Agreement to provide indemnification and contribution against certain liabilities, including liabilities under the Securities Act, subject to the terms of the Sales Agreement.

The Sales Agreement will terminate upon the earlier of (i) the issuance and sale of all of the Shares through JonesTrading on the terms and conditions set forth therein, or (ii) termination of the Sales Agreement as permitted therein. JonesTrading may terminate the Sales Agreement at any time in specified circumstances, including: in connection with the occurrence of a material adverse change with respect to the Company that, in JonesTrading’s reasonable judgment, may materially impair its ability to sell the Shares; due to the Company’s inability, refusal or failure to perform specified conditions of the Sales Agreement, subject, in certain circumstances, to the Company’s right to cure within a period of 30 days; if any other condition to JonesTrading’s obligations is not fulfilled; or any suspension of trading in the Shares or in securities generally on the Nasdaq Global Market shall have occurred. The Company and JonesTrading each has the right to terminate the Sales Agreement in its sole discretion at any time upon five days’ notice.
