The description of the Class A Common Stock set forth in the Registrant's Registration Statement on Form 8-A (File No. 000-49604), as filed with the Commission on January 25, 2002, under which the Registrant registered shares of its Class A Common Stock under Section 12(g) of Securities and Exchange Act of 1934, as amended (the "Exchange Act").

Any statement contained in this Registration Statement or any report or document incorporated into this Registration Statement by reference, however, shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained in a subsequently dated report or document that is also considered part of this Registration Statement, or in any amendment to this Registration Statement, is inconsistent with such prior statement. The Registrant's file number with the Commission is 000-49604. 2 Item 4. Description of Securities. Not applicable. Item 5. Interests of Named Experts and Counsel. Not applicable. Item 6. 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 attorneys' 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 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 Registrant's 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 3 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 Registrant's 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, Bylaws, 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. The Registrant may, to the fullest extent permitted by the DGCL, purchase and maintain insurance on behalf of any officer, director, employee or agent against any liability that may be asserted against such person. Item 7. Exemption from Registration Claimed. Not applicable. 4 Item 8. Exhibits.

Undertakings. (1) The undersigned 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 of 1933, as amended (the "Securities Act"); (ii) To reflect in the prospectus any facts or events arising after the effective date of this 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 5 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 and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" 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)(a)(i) and (1)(a)(ii) do not apply if 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 this 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; and (c) To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering. (2) The undersigned 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 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. (3) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, the Company 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 Company of expenses incurred or paid by a director, officer or controlling person of the Company 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 Company 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. 6 SIGNATURES Pursuant to the requirements of the Securities Act, 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 the City of Fairfax in the Commonwealth of Virginia, on this 4th day of March, 2002.
