                                     PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE

         The Company hereby incorporates by reference the documents listed in
(a) through (d) below. In addition, all documents subsequently filed by the
Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act") (prior to filing of a
post-effective amendment that indicates that all securities offered have been
sold or that deregisters all securities then remaining unsold) will be deemed to
be incorporated by reference in this registration statement and to be a part
hereof from the date of filing of such documents.

         (a) The Company's Annual Report on Form 10-K for the year ended
December 31, 2000, as filed with the Commission on April 2, 2001 (as amended on
Form 10-K/A filed with the Commission on May 8, 2001).

         (b) The Company's Quarterly Reports on Form 10-Q for the quarters ended
March 31, 2001, June 30, 2001 (which included the text of the 2001 Plan that is
the subject of this registration statement) and September 30, 2001, as filed
with the Commission on May 15, 2001, August 14, 2001 and November 14, 2001,
respectively.

         (c) All other reports filed pursuant to Section 13(a) or 15(d) of the
Exchange Act since December 31, 2000.

         (d) The description of the Common Stock of the Company that is

any amendment or report filed for the purpose of updating such information.

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 Certificate of Incorporation and bylaws of the Company provide that
the Company will indemnify, to the fullest extent permitted by applicable law,
its directors and officers, whether serving the Company or another corporation
at the request of the Company, against all liability and loss suffered and
expenses reasonably incurred by such persons. The Delaware General Corporation
Law contains certain provisions which establish that a



Delaware corporation may indemnify any officer or director made party to any
proceeding by reason of service in that capacity unless it is established that
the director or officer (i) did not act in good faith and in a manner reasonably
believed to be in the best interests of the Company; or (ii) with respect to a
criminal proceeding, had reasonable cause to believe his act was unlawful. As
permitted by the Delaware General Corporation Law, the bylaws of the Company
also provide that the Company will advance expenses prior to the disposition of
any proceeding provided the Company receives an undertaking by the director or
officer to repay the expenses advanced if it is ultimately determined that the
director or officer is not entitled to be indemnified.

         The Company maintains a policy of directors' and officers' liability
insurance that insures the Company's directors and officers against the cost of
defense, settlement or payment of a judgment under certain circumstances.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED

         Not applicable.

ITEM 8. EXHIBITS

         The Exhibit Index attached to this registration statement is
incorporated herein by reference.

ITEM 9. UNDERTAKINGS

         (a)  The undersigned registrant hereby undertakes:

                  (1) 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;

                           (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 (a)(1)(i) and (a)(1)(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.

                  (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.

         (b) 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 (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 the initial bona
fide offering thereof.



         (c) 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 provisions set forth in Item 6, 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.




                                   SIGNATURES

         Pursuant to the requirements of the Securities Act of 1933, 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 County of Arlington, Commonwealth of Virginia, on
this 29th day of January, 2002.
