 [Reverse of Note] 
  

Capital One Financial Corporation 
  
 6.25% Senior Notes Due November 15, 2013 
  
 This Security is one of a duly authorized issue of debt securities of the Company, of the series hereinafter specified, all issued or to be issued under a
Senior Indenture, dated as of November 1, 1996 (the “Senior Indenture”), and duly executed and delivered by the Company to BNY Midwest Trust Company, as successor to Harris Trust and Savings Bank, as trustee (hereinafter, the
“Trustee”). Reference to the Senior Indenture is hereby made for a description of the respective rights and duties thereunder of the Trustee, the Company and the Holders of the Securities. This Security is one of a series designated as the
“6.25% Senior Notes Due November 15, 2013” of the Company (hereinafter called the “Notes”), issued under the Senior Indenture. Each Holder by accepting a Note, agrees to be bound by all terms and provisions of the Senior
Indenture, as amended from time to time, applicable to the Notes. 
  
 Neither the Senior Indenture nor the Notes limit or otherwise restrict the amount of indebtedness which may be incurred or other securities which may be issued by the Company. The Notes issued under the Senior Indenture are direct,
unsecured obligations of the Company and will mature on November 15, 2013. The Notes rank on parity with all other unsecured, unsubordinated indebtedness of the Company. 
  
 The Company promises to pay interest on the principal amount of this Note at the rate per annum shown above. The Company
will pay interest semi-annually in arrears on May 15 and November 15 of each year (each an “interest payment date”), commencing on May 15, 2004. Interest on the Note will accrue from November 6, 2003 or from the most recent May 15 or
November 15, as the case may be, to which interest on the Notes has been paid or duly provided for, until payment of said principal sum has been made or duly provided for. Interest will be computed on the basis of a 360-day year of twelve 30-day
months. The Company will pay interest to the Person in whose name this Note is registered at the close of business on the May 1 or November 1, as the case may be, next preceding the applicable interest payment date. The Company will pay interest in
such coin or currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts. The Company will make payments in respect of Notes in global form (including principal and interest)
to the Holder thereof or a nominee of the Holder, by wire transfer of immediately available funds on the date such payments are due. 
  
 If the Company defaults in the payment of interest due on any interest payment date after taking into account any applicable grace period, such defaulted
interest shall be paid as set forth in the Senior Indenture. 
  
 The Notes are not redeemable prior to maturity. 
  
 The
Notes are not entitled to any sinking fund. 







 The Notes are subject to defeasance pursuant to Section 402 of the Senior Indenture. 
  
 The provisions in Section 305 of the Senior Indenture are applicable to the
Notes. 
  
 The Notes are not convertible into common stock of the
Company. 
  
 In case an Event of Default shall have occurred and
be continuing with respect to the Notes, the principal hereof may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Senior Indenture. The Senior
Indenture provides that in certain circumstances such declaration and its consequences may be waived by the Holders of a majority in aggregate principal amount of the Notes then Outstanding. However, any such consent or waiver by the Holder shall
not affect any subsequent default or impair any right consequent thereon. 
  
 The Senior Indenture permits the Company and the Trustee, without the consent of the Holders of the Notes for certain situations and with the consent of not less than two-thirds of the Holders in aggregate principal
amount of the Outstanding Notes in other situations, to execute supplemental indentures adding to, modifying, or changing various provisions of, the Senior Indenture; provided that no such supplemental indenture, without the consent of the
Holder of each Outstanding Note affected thereby, shall (i) change the Stated Maturity of the principal of, or any installment of interest on, the Notes, or reduce the principal amount thereof or the interest thereon, or change the place or currency
of payment of principal of, or interest on, the Notes, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof; (ii) reduce the percentage in principal amount of the Outstanding Notes, the
consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of the Senior Indenture or certain defaults thereunder and their
consequences) provided for in the Senior Indenture, or reduce the requirements of Section 1504 for quorum voting; or (iii) modify any of the provisions of Sections 902, 513 or 1008 of the Senior Indenture, except to increase any such percentage or
provide that certain other provisions of the Senior Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Note affected thereby. 
  
 The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 1005,
1006 or 1007 of the Senior Indenture, if before the time it would have to comply, the Holders of at least a majority in principal amount of the Outstanding Notes, by act of such Holders, either shall waive such compliance in such instance or
generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

 No reference herein to the Senior Indenture and no provision of this Note or of the Senior Indenture
shall alter or impair the obligations of the Company, which are absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note at the place, at the respective times, at the rate and in the coin and currency herein
prescribed. 
  
 The Notes are issuable in registered form without
coupons in denominations of $1,000 and any multiple thereof. A Holder may exchange the Notes for a like aggregate principal amount of Notes of other authorized denominations in the manner and subject to the limitations provided in the Senior
Indenture. 
  
 Upon due presentment for registration of transfer
of the Notes at the office or agency for said purpose of the Company, a new Note or Notes of authorized denominations, for a like aggregate principal amount, will be issued to the transferee as provided in the Senior Indenture. No service charge
shall be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto. 
  
 Prior to due presentation of this Note for registration of transfer, the Company, the Trustee, and any authorized agent of
the Company or the Trustee, may deem and treat the Holder hereof as the absolute owner of the Note (whether or not any payment with respect to this Note shall be overdue), for the purpose of receiving payment of, or on account of, the principal
hereof and, subject to the provisions herein, interest hereon and for all other purposes, and neither the Company nor the Trustee nor any authorized agent of the Company or the Trustee shall be affected by any notice to the contrary. 
  
 No recourse shall be had for the payment of the principal of, or interest on,
this Note, for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Senior Indenture or any indenture supplemental thereto, against any incorporator, shareholder, officer or director, as such, past, present or
future, of the Company or of any successor corporation, either directly or through the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment or penalty or
otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released. 
  
 THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 
  
 All terms used in this Note (and not otherwise defined in this Note) that are
defined in the Senior Indenture shall have the meanings assigned to them in the Senior Indenture.
