Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

​

As a corporation incorporated under Delaware law, the Company’s indemnification of its directors and officers is governed by the Delaware General Corporation Law (the “DGCL”). As discussed in greater detail below, the Company’s Amended and Restated Certificate of Incorporation, as amended (the “Certificate”) and Amended and Restated Bylaws (the “Bylaws”) provide indemnification to its directors and officers to the fullest extent permitted by the DGCL.

​

Section 102(b)(7) of the DGCL allows a corporation to eliminate the personal liability of a director or officer to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director or officer, except for liability of (a) a director or officer for any breach of the director’s or officer’s duty of loyalty to the corporation or its

stockholders, (b) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) a director under Section 174 of the DGCL, or (d) a director or officer for any transaction from which the director or officer derived an improper personal benefit, or (e) any officer in any action by or in the right of the corporation. Article 10 and Article 15 of the Certificate contain such provisions, and provides that if the DGCL is amended to authorize the further elimination or limitation of a director’s or officer’s liability, then the liability of our directors and officers will automatically be limited to the fullest extent provided by law.

​

In addition, Section 145 of the DGCL authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers under certain circumstances for liabilities incurred in connection with their activities in such capacities (including reimbursement for expenses incurred). Under Article 11 of the Certificate and Article 7 of the Bylaws, the Company must indemnify its directors and officers to the fullest extent permitted by the DGCL and, subject to very limited exceptions, must also advance expenses, as incurred, to its directors and officers in connection with any action, suit, or proceeding, to the fullest extent permitted by Delaware law, provided that the party seeking indemnification acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company, and had no reasonable cause to believe his or her conduct was unlawful. In addition, the Bylaws permit the Company to indemnify employees and others and advance expenses to them in connection with any action, suit, or proceeding, in the manner and to the same extent as required for directors or officers.

​

In the case of an action or suit by or in the right of the Company to procure a judgment in its favor, Section 145(b) of the DGCL and Article 7.2 of the Bylaws provide that no indemnification shall be made in respect of any claim, issue or matter as to which such party shall have been adjudged to be liable to the Company unless and only to the extent that an appropriate court shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such party is fairly and reasonably entitled to indemnity for such expenses that the court shall deem proper.

​

In addition, the Company has entered into individual indemnification agreements with each of its directors and certain officers to provide them with the procedural and substantive rights to indemnification currently set forth in the Certificate and Bylaws. The right to indemnification (and related advancement of expenses) provided by these agreements applies to all covered claims, whether such claims arose before or after the effective date of the contract, other than liabilities arising from actions or omissions (a) regarding enforcement of the indemnification agreement, if not taken in good faith; (b) relating to the purchase and sale by the director or officer of securities in violation of Section 16(b) of the Exchange Act; (c) subject to certain exceptions, in the event of claims initiated or brought voluntarily by the director or officer (rather than by way of defense, counterclaim or cross claim); or (d) for which applicable law prohibits indemnification.

​

The Company also maintains an insurance policy covering the liability of its directors and officers for actions taken in their official capacity. Under this policy, directors and officers are insured, within the limits and subject to the limitations of the policy, against certain expenses in connection with the defense of certain claims, actions, suits or proceedings, and certain liabilities which might be imposed as a result thereof, which may be brought against them by reason of their being or having been directors and officers.

​

The foregoing contains only a general summary of certain aspects of Delaware law and the Certificate and Bylaws dealing with indemnification of directors and officers as well as the form of indemnification agreement entered into between the Company and its directors and certain officers, and does not purport to be complete. It is qualified in its entirety by reference to the relevant provisions of the DGCL, the Certificate, the Bylaws, and the form of indemnification agreement, the last three of which are on file with the Commission.

Item 7. Exemption from Registration Claimed.

Not applicable.

Item 8. Exhibits.

* Filed herewith.

​

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
