PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

The following table sets forth the expenses (other than underwriting discounts, commissions, and non-accountable expense allowance) payable by the registrant in connection with the offer and sale of the securities being registered. The selling stockholders will not be responsible for any expenses in connection with the offering described in this registration statement other than underwriting discounts and commissions. All amounts are estimates except the registration and NASD filing fees.

Item 15. 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, as amended (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.

II-1

---

The registrant's Charter provides that officers and directors of the registrant shall not be liable to the registrant or its stockholders for monetary damages for conduct in their capacities as officers and directors except to the extent that elimination or limitation of officer and director liability is prohibited by Section 5-349 of the Courts and Judicial Proceedings Article of the Annotated Code of Maryland, which provides that personal liability for monetary damages may not be limited if the director or officer actually received an improper benefit or profit in money, property or services or in the event of active and deliberate dishonesty that is material to the cause of action and results in a final judgment adverse to the director or officer.

The registrant has entered into an indemnification agreement with each of its directors. Each such agreement provides that the registrant will indemnify the director to the full extent authorized or permitted by the Act or any other applicable statute or the registrant's Charter or bylaws or any amendment thereof against any obligation to pay a judgment, settlement, penalty, fine or reasonable expenses, including attorney fees (any of the foregoing, a "Liability") incurred in connection with any claim (as defined therein), including a claim by or in the right of the registrant; provided that no indemnity shall be paid by the registrant (i) if a final decision by a court having jurisdiction shall determine that such indemnification is unlawful, (ii) on account of acts or omissions by the director which are finally adjudged to have been not in good faith or to have involved intentional misconduct or a knowing violation of law, or (iii) on account of Liability under Section 16(b) of the Securities Exchange Act of 1934, as amended, or any similar provision of federal or state statutory law.

The Underwriting Agreement (Exhibit 1.1) will provide for indemnification by the underwriters of the registrant, its directors and officers, and by the registrant of the underwriters, for certain liabilities, including liabilities arising under the Securities Act of 1933, and affords certain rights of contribution with respect thereto.

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 16. Exhibits.

The exhibits to the registration statement required by Item 601 of Regulation S-K are listed in the index to exhibits at page II-5.

Item 17. Undertakings.

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 15 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 our 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.

The undersigned registrant hereby undertakes that:

        (1)   For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

        (2)   For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus 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.
