DESCRIPTION OF SECURITIES. Not applicable. ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL. Not applicable. ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS. The Company's Amended and Restated Certificate of Incorporation permits the Company to indemnify to the fullest extent permitted by Section 145 of the Delaware General Corporation Law (the "DGCL") each person that such Section grants the Company the power to indemnify. The Company's Amended and Restated Certificate of Incorporation eliminates the personal liability of directors to the Company or its stockholders for monetary damages for breaches of fiduciary duty as directors to the fullest extent permitted by Delaware law. These provisions of the Company's Amended and Restated Certificate of Incorporation are consistent with the DGCL, which permits a Delaware corporation (i) to include in its certificate of incorporation a provision limiting or eliminating a director's liability for monetary damages for breach of the duty of care and (ii) to indemnify certain individuals, including its directors, officers and employees. These provisions of the Company's Amended and Restated Certificate of Incorporation protect the Company's directors against personal liability for monetary damages resulting from breaches of their fiduciary duty of care, except as set forth below. Under the DGCL, absent these provisions, directors could be held liable for gross negligence in the performance of their duty of care but not for simple negligence. These provisions of the Company's Amended and Restated Certificate of Incorporation absolve directors of liability for negligence in the performance of their duties, including gross negligence. Directors remain liable for breaches of their duty of loyalty to the Company and its stockholders, as well as acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law and transactions from which a director derives improper personal benefit. These provisions also do not absolve directors of liability under Section 174 of the DGCL, which makes directors personally liable for unlawful dividends or unlawful stock repurchases or redemptions and expressly sets forth a negligence standard with respect to such liability. Under the DGCL, current and former directors and officers as well as other employees and individuals (and persons serving at the request of the Company as a director, officer, employee or agent for another entity) may be indemnified against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement in connection with 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 interest of the Company 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 only extends to expenses (including attorneys' fees) actually and reasonably incurred in connection with the defense or settlement of such an action and the DGCL requires court approval before there can be any indemnification of expenses where the person seeking indemnification has been found liable to the Company. The DGCL provides that the indemnification and advancement of expenses granted pursuant to it shall, unless otherwise provided when authorized, continue as to each person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. The Company maintains insurance to cover directors and officers against liability which they may incur in such capacity. 4 <Page> Except to the extent hereinabove set forth, there is no charter provision, by-law, contract, arrangement or statute under which any director or officer of the Company is insured or indemnified in any manner against any liability which he may incur in his capacity as such. Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the "Securities Act"), may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, the Company has been informed 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.

ITEM 9. UNDERTAKINGS. The undersigned registrant hereby undertakes: A. 1. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement 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. 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 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. 5 <Page> 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 this 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 Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such issue. 6 <Page> SIGNATURES Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Woodbury, New York on September 17, 2001.
