PROPOSAL NO. 3

APPROVAL OF REVERSE STOCK SPLIT</div>

Background Regarding Reverse Stock Split

Our Board has adopted and deemed advisable, and is recommending that our stockholders approve, a series of alternate amendments to the Company’s Amended and Restated Certificate of Incorporation, each of which would

effect a reverse stock split (the “Reverse Stock Split”) of all of the outstanding shares of our common stock at a ratio of between 1-for-10 and 1-for-30, inclusive; and

effect a proportionate reduction in the total number of authorized shares of our common stock (the “Authorized Shares Reduction”).

Accordingly, effecting a Reverse Stock Split would reduce the number of outstanding shares of our common stock and the Authorized Shares Reduction would reduce the total number of authorized shares of our common stock. The form of the proposed amendment to our amended and restated certificate of incorporation to effect the Reverse Stock Split is attached asAppendix Ato this Proxy Statement. However, the text of the proposed amendment is subject to revision to include such changes as may be required by the Secretary of State of the State of Delaware and as the Board deems necessary or advisable to effect the proposed amendment of our amended and restated certificate of incorporation.

Our stockholders are being asked to approve these proposed amendments pursuant to this Proposals 3, and to grant authorization to our Board of Directors to determine, in its discretion, whether to implement a Reverse Stock Split, including its specific timing and ratio, and the resulting corresponding proportionate Authorized Shares Reduction. The corresponding proportionate Authorized Shares Reduction was designed so that we do not have what some stockholders might view as an unreasonably high number of authorized shares of common stock that are unissued or reserved for issuance following the Reverse Stock Split.

By approving this proposal, stockholders will (i) approve a series of amendments to our amended and restated certificate of incorporation pursuant to which any whole number of outstanding shares between and including 10 and 30 would be combined into one share of our common stock along with a corresponding proportionate reduction in the total number of authorized shares of our common stock and (ii) authorize the Board to file only one such amendment, as determined by the Board in the manner described herein and to abandon each amendment not
