Item 6.  Indemnification of Directors and Officers.

Indemnification

Section 2-312 of the Maryland General Corporation Law (the "Act") provides that any director held liable for an unlawful distribution in violation of Section 2-311 of the Act or the corporation's charter is entitled to contribution from (i) every other director who could be held liable under Section 2-312 of the Act for the unlawful distribution and (ii) each stockholder for the amount the stockholder accepted knowing the distribution was made in violation of Section 2-311 of the Act or the corporation's charter.

Under Section 2-418 of the Act, a person who is made a party to a proceeding because such person is or was an officer or director of a corporation (an "Indemnitee") shall be indemnified by the corporation (unless the corporation's charter provides otherwise) against reasonable expenses incurred by the Indemnitee in connection with the proceeding if the Indemnitee is successful on the merits or otherwise or if ordered by a court of competent jurisdiction. In addition, under said section a corporation is permitted to indemnify an Indemnitee against liability incurred in a proceeding unless (i) the Indemnitee's act or omission was material to the matter giving rise to the proceeding and (a) was committed in bad faith or (b) was the result of active and deliberate dishonesty; (ii) the Indemnitee actually received an improper personal benefit in money, property, or services; (iii) in the case of a criminal proceeding, the Indemnitee had reasonable cause to believe that the act or omission was unlawful; (iv) the Indemnitee was adjudged liable to the corporation in a proceeding by or in the right of the corporation; or (v) the Indemnitee was adjudged liable on the basis that he or she improperly received a personal benefit.

As authorized by the Act, Article V of the registrant's Articles of Amendment and Restatement (the "Charter") provides that the registrant shall indemnify each of its officers and directors to the fullest extent permissible under the Act, as the same exists or may hereafter be amended, against all liabilities, losses, judgments, penalties, fines, settlements and reasonable expenses (including attorney fees) incurred or suffered by such person by reason of or arising from the fact that such person is or was an officer or director of the registrant or is or was serving at the request of the registrant as a director, officer, partner, trustee, employee or agent of another foreign or domestic corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. Such indemnification continues as to a person who has ceased to be a director, officer, partner, trustee, employee or agent and inures to the benefit of his or her heirs, executors, and administrators.

Effective April 10, 2012, the registrant entered into indemnification agreements with each of its outside directors. Under the indemnification agreements, the registrant has agreed, to the fullest extent permitted by the laws of the State of Maryland, and in accordance with the terms, conditions and limitations set forth in the indemnification agreements, to indemnify each of its outside directors against all judgments, penalties, fines and amounts paid in settlement and all expenses actually and reasonably incurred, in connection with various legal proceedings including, without limitation, a lawsuit, arbitration, administrative hearing or investigation, whether by or in the right of the registrant or otherwise. This right to indemnification will extend to actions taken by the director in other capacities in which he or she is serving at the request of the registrant, such as a director or officer of a subsidiary or a fiduciary or trustee of an employee benefit plan. Indemnification is not available if the act or omission by the director was material to the matter in question and the director acted in bad faith, with active and deliberate dishonesty, or in a manner that he or she had reasonable cause to believe was unlawful, or actually received an improper personal benefit. Indemnification is also generally not available if the proceeding is by or on behalf of the registrant and the director is found to be liable to the registrant or if the proceeding is brought by the director against the registrant. The indemnification agreements include a presumption that the director is entitled to indemnification, imposing on the registrant the burden of overcoming that presumption. The indemnification agreements also put in place specific processes and procedures for indemnification claims and advancement of expenses and costs.

Insurance

The registrant maintains directors' and officers' liability insurance under which the registrant's directors and officers are insured against loss (as defined) as a result of claims brought against them based upon their acts or omissions in such capacities, including civil liabilities under the Securities Act of 1933.

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 (“Securities Act”);

(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;

(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 periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 (“Exchange Act”) that are incorporated by reference in the 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 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to 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.

(h)           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 provisions described in Item 6 above, 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 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. The undertaking of the registrant in the preceding sentence does not apply to insurance against liability arising under the Securities Act.
