PART I. INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS The information required by Part I is included in documents sent or given to participants in the plans specified on the cover page of this Registration Statement, pursuant to Rule 428(b)(1) of the Securities Act. PART II. INFORMATION REQUIRED IN THE REGISTRATION STATEMENT Item 3. Incorporation of Certain Documents by Reference. ----------------------------------------------- The Registrant is subject to the informational and reporting requirements of Sections 13(a), 14 and 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance therewith files reports, proxy statements and other information with the Securities and Exchange Commission (the "Commission"). The following documents, which are filed with the Commission, are incorporated in this Registration Statement by reference: (1) The Registrant's latest annual report filed pursuant to Section 13(a) or 15(d) of the Exchange Act or either (1) the latest prospectus filed pursuant to Rule 424(b) under the Securities Act that contains audited financial statements for the Registrant's latest fiscal year for which such statements have been filed or (2) the Registrant's effective registration statement on Form 10 or 20-F filed under the Exchange Act containing audited financial statements or the Registrant's latest fiscal year; (2) All other reports filed pursuant to Section 13(a) or 15(d) of the Exchange Act since the end of the fiscal year covered by the registrant document referred to in (1) above. (3) The description of the Class A Common Stock, $0.01 par value per share (the "Common Stock"), contained in the Company's Registration Statement on Form 8-A as filed with the Commission on October 15, 1997, including any amendment or report filed for the purpose of updating such description.

Item 4. Description of Securities. -------------------------- Not applicable. Item 5. Interests of Named Experts and Counsel. --------------------------------------- Not applicable. Item 6. Indemnification of Directors and Officers. ------------------------------------------ The Registrant's Second Amended and Restated Certificate of Incorporation contains certain provisions permitted under the General Corporation Law of Delaware relating to the liability of directors. These provisions eliminate a director's personal liability for monetary damages for a breach of fiduciary duty, except in certain circumstances involving wrongful acts, such as the breach of a director's duty of loyalty or acts or omissions which involve intentional misconduct or a knowing violation of the law. The Registrant's Second Amended and Restated Certificate of Incorporation also contains provisions obligating the Registrant to indemnify its directors and officers to the fullest extent permitted by the General Corporation Law of Delaware. The Registrant maintains insurance coverage insuring directors and officers of the Registrant against certain liabilities which they may incur as directors and officers of the Registrant, which may include coverage for liabilities arising under the Securities Act. Section 145 of the General Corporation Law of Delaware provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against amounts paid and expenses incurred in connection with an action or proceeding to which he is or is threatened to be made a party by reason of such position, if such person shall have 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, in any criminal proceeding, if such person had no reasonable cause to believe his conduct was unlawful; provided that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the adjudicating court determines that such indemnification is proper under the circumstances. Item 7. Exemption From Registration Claimed. ------------------------------------ Not applicable. Item 8. Exhibits. --------- The Exhibit Index immediately preceding the exhibits is incorporated herein by reference. Item 9. Undertakings. ------------- 1. The Registrant hereby undertakes: (a) 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; (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; and (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 (i) and (ii) do not apply if the registration statement is on Form S-3 or Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement. (b) 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. (c) 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. 2. The 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 Section 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 in the initial bona fide offering thereof. 3. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, executive 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 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, executive officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, executive 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.

We have examined the Certificate of Incorporation of the Company and the By-Laws of the Company, each as amended to date, and originals, or copies certified to our satisfaction, of all pertinent records of the meetings of the directors and stockholders of the Company, the Registration Statement and such other documents relating to the Company as we have deemed material for the purposes of this opinion. In our examination of the foregoing documents, we have assumed the genuineness of all signatures and the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified or photostatic copies, and the authenticity of the originals of such latter documents. We assume that the appropriate action will be taken, prior to the offer and sale of the shares in accordance with the Plans, as the case may be, to register and qualify the shares for sale under all applicable state securities or "blue sky" laws.
