Item 6.

Indemnification of Directors and Officers.

Section 2-405.2 of the Maryland General Corporation Law permits a Maryland corporation to include in its charter a provision limiting the liability of its directors and officers to the corporation or its stockholders for money damages except: (1) to the extent it is proven that the director or officer actually received an improper benefit or profit in money, property or services for the amount of the benefit or profit in money, property or services actually received; or (2) to the extent that a judgment or other final adjudication adverse to the director or officer is entered in a proceeding based on a finding that the director’s or officer’s action or failure to act was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding. The Company’s charter contains such a provision, thereby limiting the liability of its directors and officers to the maximum extent permitted by Maryland law.

Section 2-418 of the Maryland General Corporation Law permits a Maryland corporation to indemnify a director or officer who is made a party to any proceeding by reason of service in that capacity against judgments, penalties, fines, settlements and reasonable expenses actually incurred unless it is established that: (1) the act or omission of the director or officer was material to the matter giving rise to the proceeding and was committed in bad faith or was the result of active and deliberate dishonesty; (2) the director or officer actually received an improper personal benefit in money, property or services; or (3) in the case of a criminal proceeding, the director or officer had reasonable cause to believe that his or her conduct was unlawful. The Maryland General Corporation Law provides that where a director or officer is a defendant in a proceeding by or in the right of the corporation, the director or officer may not be indemnified if he or she is found liable to the corporation. The Maryland General Corporation Law also provides that a director or officer may not be indemnified in respect of any proceeding alleging improper personal benefit in which he or she was found liable on the grounds that personal benefit was improperly received. A director or officer found liable in a proceeding by or in the right of the corporation or in a proceeding alleging improper personal benefit may petition a court to nevertheless order indemnification of expenses if the court determines that the director or officer is fairly and reasonably entitled to indemnification in view of all the relevant circumstances.

Section 2-418 of the Maryland General Corporation Law provides that unless limited by the charter of a Maryland corporation, a director or an officer who is successful on the merits or otherwise in defense of any proceeding must be indemnified against reasonable expenses. Section 2-418 also provides that a Maryland corporation may advance reasonable expenses to a director or an officer upon the corporation’s receipt of (a) a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation and (b) a written undertaking by the director or officer or on his or her behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the standard of conduct was not met.

The Company’s charter provides for indemnification of directors and officers to the maximum extent permitted by the Maryland General Corporation Law.

Under a directors’ and officers’ liability insurance policy, directors and officers of the Company are insured against certain liabilities.

Exhibits.

See Exhibit Index.

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 of 1933;

(ii)            To reflect in the prospectus any facts or events arising after the effective date of the 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 the 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; and

(iii)           To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the 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 Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act of 1933, 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 of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) 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 of 1933 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 Securities and Exchange Commission such indemnification is against public policy as expressed in the 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 Act and will be governed by the final adjudication of such issue.
