                    AGREEMENT REGARDING REGISTRATION OF SHARES

     This AGREEMENT REGARDING REGISTRATION OF SHARES ("Agreement") is made as of
May 17, 2004 by and between NAVTEQ Corporation ("Company") and NavPart I B. V.
("Stockholder").

     WHEREAS, the Company has filed a registration statement on Form S-1
("Registration Statement") with the Securities and Exchange Commission under the
Securities Act of 1933, as amended, ("Act") to register the offer and sale of
certain shares of the Company's common stock, $0.001 par value, held by Philips
Consumer Electronic Services B. V. ("Philips") pursuant to a firm commitment
underwritten public offering ("Offering"); and

     WHEREAS, the Stockholder has requested that the Company register the offer
and sale under the Act certain shares of the Company's common stock it holds
("Stockholder Shares") by including such shares in the Registration Statement;
and

     WHEREAS, the Company has indicated its willingness to include such
Stockholder Shares in the Registration Statement, subject to the terms and
conditions specified in this Agreement.

     NOW, THEREFORE, in consideration of the mutual promises and covenants
contained herein, the parties agree as follows:

1.   AGREEMENT TO REGISTER SHARES. Subject to the conditions set forth herein,
the Company agrees to use its commercially reasonable efforts to register the
Stockholder Shares by including such shares in the Registration Statement. The
number of Stockholder Shares to be registered will be determined through
consultation with Credit Suisse First Boston LLC and Merrill Lynch & Co., the
Underwriters of the Offering. Such number of shares may be increased or
decreased at any time prior to the completion of the Offering in the sole
discretion of the Underwriters.

2.   CONDITIONS TO COMPANY'S OBLIGATION. In addition to the condition set forth
in Section 5 below, the obligations of the Company to include the Stockholder
Shares in the Registration Statement are expressly subject to the following
conditions:

     (a)  the Stockholder shall become a party to the Underwriting Agreement
between the Company, the Underwriters, Philips and the Stockholder;

     (b)  the Stockholder cooperates with the Company and the Underwriters as
requested by the Company and/or Underwriters in connection with the Registration
Statement and the Offering, including, without limitation, providing such
information as is requested by them for inclusion in the Registration Statement
and executing such agreements, acknowledgments and certificates as are customary

3.   FEES AND EXPENSES. The Company shall be responsible for the Securities and
Exchange Commission, National Association of Securities Dealers, Inc., New York

selling commissions and transfer taxes, if any, applicable to the sale of the
Stockholder Shares, and the fees and expenses of its counsel.

4.   NO OTHER REGISTRATION RIGHTS. The Stockholder acknowledges and agrees that
the Company's agreement to register the Stockholder Shares pursuant to this
Agreement does not create any further right of Stockholder to have any of its
shares registered in any subsequent registration of the offer and sale of
Company securities under the Act (whether in an offering by the Company or for
the account of any Company securityholder). The Stockholder further acknowledges
and agrees that nothing in this Agreement is intended to make the Stockholder a
party to or confer upon such Stockholder any rights set forth in that certain
Registration Rights Agreement dated as of March 29, 2001 by and between the
Company and Philips.

5.   AGREEMENT OF UNDERWRITERS. The obligations of the Company and the rights of
the Stockholder under this Agreement are expressly conditioned on the consent
and agreement of the Underwriters to include the Stockholder Shares in the
Offering. In the event that the Underwriters determine, in their sole
discretion, not to include the Stockholder Shares in the Offering, the Company's
obligations under this Agreement shall cease and be of no further force or
effect.

6.   REASONABLE INVESTIGATION. In connection with the preparation and filing of
the Registration Statement and the completion of the Offering, the Company will
provide the Stockholder reasonable and customary access to the Company's books
and records and such opportunities to discuss the business of the Company with
its officers as shall be reasonably necessary to conduct a reasonable
investigation within the meaning of the Act.

7.   NON-TRANSFERABILITY. The rights and obligations of the Stockholder under
this Agreement may not be transferred or assigned without the written agreement
of the Company.

8.   GOVERNING LAW. This Agreement and the rights and obligations of the parties
hereto shall be governed by and construed in accordance with the laws of the
state of Delaware, but not including the choice of law rules thereof.

9.   ENTIRE AGREEMENT. This Agreement constitutes the full and entire
understanding and agreement of the parties with regard to the subject matters
described herein and supersedes and any and all prior agreements and
understandings between the parties with regard to the subject matters described
herein. This Agreement may be amended or modified only by written agreement of
the parties.
