Item 15.  Indemnification of Directors and Officers

   Section 145(a) of the General Corporation Law of the State of Delaware
("Delaware Corporation Law") provides, in general, that a corporation shall
have the power to 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 an action by or in the right of the corporation), because the person is or
was a director or officer of the corporation. Such indemnity may be against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by the person in connection with
such action, suit or proceeding, if the 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 corporation and if, with respect to any criminal action or
proceeding, the person did not have reasonable cause to believe the person's
conduct was unlawful.

   Section 145(b) of the Delaware Corporation Law provides, in general, that a
corporation shall have the power to indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in
its favor because the person is or was a director or officer of the
corporation, against any expenses (including attorneys' fees) actually and
reasonably incurred by the person in connection with the defense or settlement
of such action or suit if the 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
corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

   Section 145(g) of the Delaware Corporation Law provides, in general, that a
corporation shall have the power to purchase and maintain insurance on behalf
of any person who is or was a director or officer of the corporation against
any liability asserted against the person in any such capacity, or arising out
of the person's

                                     II-1



status as such, whether or not the corporation would have the power to
indemnify the person against such liability under the provisions of the law.

   Article XI of Capital One Financial Corporation's Restated Certificate of
Incorporation, as amended, and Section 6.7 of Capital One Financial
Corporation's Bylaws provide, in general, for mandatory indemnification of
directors and officers to the extent permitted by law, against liability
incurred by them in proceedings instituted or threatened against them by third
parties, or by or on behalf of Capital One Financial Corporation itself,
relating to the manner in which they performed their duties unless they have
been guilty of willful misconduct or of a knowing violation of the criminal law.

   For the undertaking with respect to indemnification, see Item 17 below.

   Reference is made to the underwriting agreements, which are filed as
Exhibits 1.1.1 and 1.1.2 to this registration statement, relating to Capital

Item 17.  Undertakings

   (a) Each of the undersigned registrants 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 of 1933;

     (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. Notwithstanding the 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 end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Securities and Exchange Commission pursuant
          to Rule 424(b) if, in the aggregate, the changes in volume and price
          represent no more than a 20% change in the maximum aggregate offering
          price set forth in the "Calculation of Registration Fee" table in the
          effective 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 (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 with the Securities
   and Exchange Commission by a registrant pursuant to Section 13 or Section
   15(d) of the Securities Exchange Act of 1934 that are incorporated by
   reference in this 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 to
   be the initial bonafide 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)  Each of the undersigned registrants hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, each
filing of a registrant's annual report pursuant to Section 13(a) or 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 herein, and the offering of such
securities at that time shall be deemed to be the initial bonafide offering
thereof.

   (c)  Insofar as indemnification for liabilities arising under the Securities
Act of 1993 may be permitted to directors, officers and controlling persons of
each registrant pursuant to the provisions described under Item 15 above, or
otherwise, each registrant has been advised that in the opinion of 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 each
registrant of expenses incurred or paid by a director, officer or controlling
person of each 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, each 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 final adjudication of such issue.
