     Re:      First National Master Note Trust, Series 2003-1 Asset Backed Notes

Ladies and Gentlemen:

At your request, we have examined the Registration Statement on Form S-3
(Registration Nos. 333-86574-00 and 333-86574-01) of First National Funding LLC
(the "LLC") and First Bankcard Master Credit Card Trust (the "Master Trust")
(collectively, the LLC and the Master Trust are referred to herein as the
"Co-Registrants"), together with the exhibits thereto, as amended (the
"Registration Statement") registering notes representing debt of First National
Master Note Trust (the "Trust"), and the related Prospectus, dated March 13,
2003, and Prospectus Supplement, dated March 13, 2003 (collectively, the
"Prospectus"), filed by the Co-Registrants with the Securities and Exchange
Commission (the "Commission") pursuant to Rule 424(b) under the Securities Act
of 1933, as amended (the "Act"), relating to the issuance of $415,000,000 Class
A Series 2003-1 Asset Backed Notes, $38,750,000 Class B Series 2003-1 Asset
Backed Notes and $46,250,000 Class C Series 2003-1 Asset Backed Notes (the
"Series 2003-1 Notes"). The Series 2003-1 Notes will be issued pursuant to the
Master Indenture, dated as of October 24, 2002 (the "Master Indenture"), a copy
of which is included as Exhibit 4.1 to the Form 8-K filed with the Commission on
November 4, 2002, as supplemented by an Indenture Supplement, dated as of March
20, 2003 (the "Indenture Supplement", and together with the Master Indenture,
the "Indenture"), a copy of the form of which is included as Exhibit 4.2 to the
Registration Statement, and the specific terms of which are summarized in the
Prospectus, each by and between the Trust and The Bank of New York, as indenture
trustee (the "Indenture Trustee"). We are familiar with the proceedings taken by
the LLC as transferor in connection with the authorization of the issuance and
sale of the Series 2003-1 Notes, and have examined such documents and such
questions of law and fact as we have deemed necessary in order to express the
opinion hereinafter stated. This opinion letter is furnished in accordance with
the requirements of Item 16 of Form S-3 and Item 601(b)(5)(i) of Regulation S-K.

We are opining herein as to the effect on the subject transactions of only
United States federal law and the laws of the State of Nebraska, and we express
no opinion with respect to the applicability thereto or the effect thereon of
the laws of any other jurisdiction or as to any matters of municipal law or the
laws of any local agencies within any state.

Based on the foregoing, we are of the opinion, as of the date hereof, that the
Series 2003-1 Notes, upon issuance and sale thereof in the manner described in
the Prospectus and as provided in the Indenture, will be legally issued and
binding obligations of the Trust, subject to the effects of bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium and other similar
laws relating to or affecting creditors' rights generally and general equitable
principles, including, without limitation, concepts of materiality,
reasonableness, good faith and fair dealing and the possible unavailability of
specific performance or injunctive relief, regardless of whether considered in a
proceeding in equity or at law and the discretion of the court before which any
proceeding therefore may be brought.

In rendering our opinion, we have assumed that, upon or prior to the issuance
and sale of the Series 2003-1 Notes, (i) the Indenture Supplement will be duly
authorized, executed and delivered by the parties thereto, (ii) all documents
required to be executed and delivered in connection with the issuance and sale
of the Series 2003-1 Notes will be so executed and delivered by properly
authorized persons, and (iii) the purchase price for the Series 2003-1 Notes
will be paid to the LLC by the various underwriters named in the Prospectus.

We hereby consent to the filing of this opinion letter as an exhibit to the
Co-Registrant's Current Report on Form 8-K, dated on or about March 14, 2003 and
to the references to this firm under the heading "Legal Matters" in the
Prospectus. In giving such consent we do not admit that we are "experts" within
the meaning of the Act or the rules and regulations of the Commission issued
thereunder, with respect to any part of the Registration Statement or
Prospectus, including this opinion letter as an exhibit or otherwise.

                                Very truly yours,

                                /s/ Kutak Rock LLP
