Description of Registrant's Securities Registered Pursuant to Section 12 of the Securities Exchange Act of 1934

Our authorized capital stock consists of 60,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share, all of which shares of preferred stock are undesignated. Our board of directors may establish the rights and preferences of the preferred stock from time to time. There are currently no outstanding shares of preferred stock.

Our board of directors has the authority, without further action by our stockholders, to issue from time to time the undesignated preferred stock in one or more series and to fix the number of shares, designations, preferences, powers, and relative, participating, optional or other special rights and the qualifications or restrictions thereof. The preferences, powers, rights and restrictions of different series of preferred stock

may differ with respect to dividend rates, amounts payable on liquidation, voting rights, conversion rights, redemption provisions, sinking fund provisions, purchase funds and other matters. The issuance of preferred stock could decrease the amount of earnings and assets available for distribution to holders of our common stock or adversely affect the rights and powers, including voting rights, of the holders of our common stock, and may have the effect of delaying, deferring or preventing a change in control of our company.

We are subject to Section 203 of the Delaware General Corporation Law which prohibits persons deemed “interested stockholders” from engaging in a “business combination” with a Delaware corporation for three years following the date these persons become interested stockholders. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the board of directors.

In addition, we have implemented other anti-takeover provisions or provisions that could have an anti-takeover effect, including advance notice requirements for director nominations and stockholder proposals, no cumulative voting for directors, director vacancies are filled by remaining directors (including vacancies resulting from removal), and the number of directors is fixed by the board of directors, and the board of directors can increase or decrease the size of the board of directors without stockholder approval (within the range set forth in our certificate of incorporation and bylaws). These provisions, and others that our board of directors may adopt hereafter, may discourage offers to acquire us and may permit our board of directors to choose not to entertain offers to purchase us, even if such offers include a substantial premium to the market price of our stock. Therefore, our stockholders may be deprived of opportunities to profit from a sale of control.

We have adopted provisions in our certificate of incorporation that limit the liability of our directors for monetary damages for breach of their fiduciary duties, except liability for any of the following under applicable law: (1) any breach of their duty of loyalty to the corporation or the stockholders; (2) acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law; (3) unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or (4) any transaction from which the director derived an improper personal benefit. This limitation of liability does not apply to liabilities arising under the federal securities laws and does not affect the availability of equitable remedies such as injunctive relief or rescission.

Our certificate of incorporation and bylaws provide that we will indemnify our directors, executive officers, employees and other agents to the fullest extent permitted by the Delaware General Corporation Law. Our bylaws also permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in such capacity. We have entered into separate indemnification agreements with our directors, in addition to the indemnification provided for in our bylaws.

Actions under the Securities Act. Unless we otherwise consent in writing, the United States federal district courts shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended (the “Securities Act”). If any action arising under the Securities Act is filed in a court other than a federal district court in the name of any stockholder (current, former or future), such stockholder shall be deemed to have consented to: (i) the personal jurisdiction of the federal district courts in connection with any action brought in any such court to enforce the federal forum selection provision, and (ii) having service of process made upon such stockholder in any such enforcement action by service upon such stockholder’s counsel in the enforcement action as agent for such stockholder.

State Law Claims. Unless we otherwise consent in writing, the Court of Chancery of the State of Delaware or, if the Court of Chancery of the State of Delaware does not have jurisdiction, another state or federal court located within the State of Delaware, shall be the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, (3) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation or bylaws, or (4) any action asserting a claim governed by the internal affairs doctrine. If any such action is filed in a court other than a court located within the State of Delaware in the name of any stockholder, such stockholder shall be deemed to have consented to: (i) the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce the Delaware forum selection provision, and (ii) having service of process made upon such stockholder in any such enforcement action by service upon such stockholder’s counsel in the foreign action as agent for such stockholder.
