Item 4.  Description of Securities

Not applicable.

Item 5.  Interests of Named Experts and Counsel

None.

Item 6.  Indemnification of Directors and Officers

Indemnification. Article VI of the Company’s certificate of incorporation provides that, unless expressly prohibited by law, the Company shall indemnify a director or officer of the Company or of a subsidiary of the Company against his reasonable expenses and all liabilities in connection with any proceeding involving that director or officer of the Company or a wholly-owned subsidiary of the Company, including a proceeding by or in the right of the Company or its wholly-owned subsidiary, unless such breach of duty is based on an act or omission (a) in breach of such person’s duty of loyalty to the Company or its shareholders; (b) not in good faith or involving a knowing violation of law; or (c) resulting in receipt by such person of an improper personal benefit. The Company shall advance or pay those reasonable expenses incurred by such director or officer in a proceeding as and when incurred, provided, however, that the director or officer shall, as a condition to receipt of such advances, undertake to repay all amounts advanced if it shall finally be adjudicated that the breach of duty by the director or officer was based upon an act or omission (a) in breach of such person’s duty of loyalty to the Company (and/or its subsidiary) or its shareholders; (b) not in good faith or involving a knowing violation of law; or (c) resulting in receipt by such person of an improper personal benefit.

The New Jersey Business Corporation Act empowers a corporation to indemnify a corporate agent against his expenses and liabilities incurred in connection with any proceeding (other than a derivative lawsuit) involving the corporate agent by reason of his being or having been a corporate agent if (a) the agent acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and (b) with respect to any criminal proceeding, the corporate agent had no reasonable cause to believe his conduct was unlawful. For purposes of the Act, the term “corporate agent” includes any present or former director, officer, employee or agent of the corporation, and a person serving as a “corporate agent” at the request of the corporation for any other enterprise.

With respect to any derivative action, the corporation is empowered to indemnify a corporate agent against his expenses (but not his liabilities) incurred in connection with any proceeding involving the corporate agent by reason of his being or having been a corporate agent if the agent acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation. However, only the court in which the proceeding was brought can empower a corporation to indemnify a corporate agent against expenses with respect to any claim, issue or matter as to which the agent was adjudged liable for negligence or misconduct.

The corporation may indemnify a corporate agent in a specific case if a determination is made by any of the following that the applicable standard of conduct was met: (i) the board of directors, or a committee thereof, acting by a majority vote of a quorum consisting of disinterested directors; (ii) by independent legal counsel, if there is not a quorum of disinterested directors or if the disinterested quorum empowers counsel to make the determination; or (iii) by the shareholders.

A corporate agent is entitled to mandatory indemnification to the extent that the agent is successful on the merits or otherwise in any proceeding, or in defense of any claim, issue or matter in the proceeding. If a corporation fails or refuses to indemnify a corporate agent, whether the indemnification is permissive or mandatory, the agent may apply to a court to grant him the requested indemnification. In advance of the final disposition of a proceeding, the corporation may pay an agent’s expenses if the agent agrees to repay the expenses unless it is ultimately determined he is entitled to indemnification.

Exculpation. Article VI of the Company’s certificate of incorporation provides that no director or officer of the Company, or of a subsidiary of the Company, shall be personally liable to the Company or to its shareholders for damages for breach of any duty owed to the Company or its shareholders unless such breach of duty is based on an act or omission (a) in breach of such person’s duty of loyalty to the Company (and/or its subsidiary) or its shareholders;

(b) not in good faith or involving a knowing violation of law; or (c) resulting in receipt by such person of an improper benefit.

Insurance. The Company maintains insurance policies insuring the Company’s directors and officers against liability for wrongful acts or omissions arising out of their positions as directors and officers, subject to certain limitations.

Item 7.  Exemption From Registration Claimed.

Not applicable.

Item 8.  List of Exhibits.

The undersigned registrant hereby undertakes:

1. To file, during any period in which offers or sales are being made, a post-effective amendment to the 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 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) (Section 230.424(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 Filing Fees” 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 1(i) and 1(ii) above do not apply if the information required to be included in a post-effective amendment by these paragraphs is contained in reports filed with or furnished to the Commission by the Company 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;

4. 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 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; and

5. 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.
