     Any statement contained in a document incorporated or deemed to be

for purposes of this Registration Statement to the extent that a statement

Statement.

Item 4.  Description of Securities.

     Not applicable.

Item 5. Interests of Named Experts and Counsel.

     Not applicable.

Item 6.  Indemnification of Directors and Officers.

     Under the Company's By-Laws, and in accordance with Section 145 of the
Delaware General Corporation Law (the "GCL"), the Company shall indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than any action or suit by or
in the right of the Company to procure a judgment in its favor, which is
hereinafter referred to as a "derivative action") by reason of the fact that
such person is or was a director, officer or employee of the Company, or is or
was serving in such capacity or as agent at the request of the Company for
another entity, to the full extent authorized by Delaware law, against expenses
(including, but not limited to, attorneys' fees), judgments, fines and amounts
actually and reasonably incurred in connection with the defense or settlement of
such action, suit or proceeding if such person acted in good faith and in a
manner the person reasonably believed to be in or not opposed to the best
interests of the Company, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe was unlawful. Agents of the
Company may be similarly indemnified, at the discretion of the Board of
Directors.

     Under Section 145 of the GCL, a similar standard of care is applicable in
the case of derivative actions, except that indemnification only extends to
expenses (including attorneys' fees) incurred in connection with the defense or
settlement of such an action and then, where the person is adjudged to be liable
to the Company, only if and to the extent that the Court of Chancery of the
State of Delaware or the court in which such action was brought determines that
such person is fairly and reasonably entitled to such indemnity and only for
such expenses as the court shall deem proper.

     Pursuant to the Company's By-Laws, a person eligible for indemnification
may have the expenses incurred in connection with any matter described above
paid in advance of a final disposition by the Company. However, such advances
will only be made upon the delivery of an undertaking by or on behalf of the
indemnified person to repay all amounts so advanced if it is ultimately
determined that such person is not entitled to indemnification.

     In addition, under the Company's By-Laws, the Company may purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the Company or of another corporation against any liability
asserted against and incurred by such person in such capacity, or arising out of
the person's status as such whether or not the Company would have the power or
the obligation to indemnify such person against such liability under the
provisions of the Company's By-Laws.

Item 7.  Exemption from Registration Claimed.

     Not applicable.

Item 9.  Undertakings.

     The Company 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:

     (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 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 this Registration Statement;
and

     (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 (i) and (ii) above 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 with or
furnished to the Commission 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 purposes 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) That, for purposes of determining any liability under the Securities Act,
each filing of the Company's annual report pursuant to Section 13(a) or Section
15(d) of the Exchange Act 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
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 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 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.

                                   SIGNATURES

     The Registrant. Pursuant to the requirements of the Securities Act, the

authorized, in the City of Arlington, Commonwealth of Virginia, on this 23rd day
of March, 2001.
