Indemnification of Directors and Officers. Section 145 of the Delaware General Corporation Law (DGCL) generally provides that all directors and officers (as well as other employees and individuals) may be indemnified against expenses (including attorney's fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with certain specified actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation -- a "derivative action"), if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard of care is applicable in the case of derivative actions, except that indemnification extends only to expenses (including attorneys' fees) actually and reasonably incurred in connection with defense or settlement of an action and the DGCL requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. Section 145 of the DGCL also provides that the rights conferred thereby are not exclusive of any other right which any person may be entitled to under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, and permits a corporation to advance expenses to or on behalf of a person to be indemnified upon receipt of an undertaking to repay the amounts advanced if it is determined that the person is not entitled to be indemnified. The registrant's certificate of incorporation and bylaws provide that each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding by reason of the fact that he is or was a director or officer of the registrant (or is or was serving at the request of the registrant as director, officer, employee or agent of another entity), shall be indemnified and held harmless by the registrant to the fullest extent authorized by the DGCL, as in effect (or to the extent that indemnification is broadened, as it may be amended), against all expense, liability and loss (including attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith. Except II-1 with respect to actions initiated by an officer or director against the registrant to recover the amount of an unpaid claim, the registrant is required to indemnify an officer or director in connection with an action, suit or proceeding initiated by such person only if such action, suit or proceeding was authorized by the board of directors of the registrant. The certificate of incorporation and bylaws further provide that an officer or director may (60 days after a written claim has been received by the registrant) bring suit against the registrant to recover an unpaid claim and, if such suit is successful, the expense of bringing such suit. While it is a defense to such suit that the claimant has not met the applicable standards of conduct which make indemnification permissible under the DGCL, neither the failure of the board of directors to have made a determination that indemnification is proper, nor an actual determination that the claimant has not met the applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct. The certificate of incorporation and bylaws also provide that the rights conferred thereby are contract rights, that they are not exclusive of any other rights which an officer or director may have or hereafter acquire under any statute, any other provision of the certificate of incorporation, bylaw, agreement, vote of stockholders or disinterested directors or otherwise, and that they include the right to be paid by the registrant the expenses incurred in defending any specified action, suit or proceeding in advance of its final disposition provided that, if the DGCL so requires, such payment shall only be made upon delivery to the registrant by the officer or director of an undertaking to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under the bylaws or otherwise. Item 15. Recent Sales of Unregistered Securities. On September 17, 2001, we made a net contribution of 6,628 shares of the Class A common stock of our predecessor company, a New Jersey corporation, to the Employee Stock Ownership Plan Trust. The transaction described above was undertaken in reliance upon the exemptions from the registration requirements of the Securities Act of 1933 afforded by Rule 701 promulgated thereunder, as a transaction pursuant to the compensatory benefit plans and contracts relating to compensation. The registrant believes that exemptions other than the foregoing exemption may exist for this transaction. Item 16. Exhibits and Financial Statement Schedule.

II-6 Item 17. Undertakings (a) The undersigned registrant hereby undertakes to provide to the underwriters, at the closing specified in the underwriting agreement, certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser. (b) 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 Securities Act and will be governed by the final adjudication of such issue. (c) 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.
