MODIFICATION OF THE WARRANTY AGREEMENT DATED 08.09.98

Dear Sir or Madam,

When reviewing the Warranty Agreement, we have noticed that this must be adapted
to current practice in two points:

The emissions requirements of the American authorities do not refer to exhaust
gas emissions, rather to other types of vehicle emissions (e.g. through
permeation). For this reason, the corresponding opening clause in subparagraph 2
of the Warranty Agreement should be changed as follows:

         "To the extent that exhaust, emission, or safety-relevant parts exceed
         the above-mentioned warranty periods by following valid warranty period
         or kilometric performances resulting from mandatory or other
         regulations, the longer time periods apply."

To the extent that nothing else results from the above, subparagraph 2 of the
Warranty agreement remains unaffected.

Various companies of the BMW Group use other conditions for purchasing besides
the purchasing conditions for production materials and car components stated in
the Warranty Agreement. For this reason, the reference should be agreed upon as
follows, as a departure from subparagraph 1:

         "To the extent that nothing differing has been regulated in this
         agreement, the prevailing BMW purchasing conditions given in the BMW
         order are applicable for fault liability."

To show your consent to the above changes, we kindly ask you to return a signed
copy of this letter to us. We have noted the 19.06.02 for the receipt of you
reply. We are looking forward to continuing the supply relationship with your
company in a partnership-like manner based on the changed Warranty Agreement.

Yours sincerely,

18.      FORM & EFFECT OF AGREEMENT

18.1     Entire Agreement. This Agreement together with its Schedules and other
         attachments (if any) constitutes the entire agreement between the
         parties regarding the subject matter hereof and supersedes any and all
         prior negotiations, promises, commitments, undertakings, and agreements
         of the parties relating thereto.

18.2     Counterparts. This Agreement may be executed in counterparts, each of
         which shall be an original, but all of which together shall constitute
         one instrument.

18.3     Modification. This Agreement may be modified or amended only by a
         written instrument duly executed by the parties hereto.

18.4     Waiver of Breach. No waiver of any kind under this Agreement will be
         deemed effective unless set forth in writing and signed by the party
         charged with such waiver, and no waiver of any right arising from any
         breach or failure to perform will be deemed to be a waiver or
         authorization of any other breach or failure to perform or of any other
         right arising under this Agreement.

18.5     Notices. All notices required or permitted under this Agreement shall
         be delivered by hand, fax or nationally recognized overnight courier
         addressed if to NAVTECH and if to LICENSEE at the NAVTECH Address and
         the LICENSEE Address, respectively, set forth in ARTICLE 1 of this
         Agreement, or at such other address as either party shall have
         furnished to the other in writing. All such notices and other written
         communications shall be effective (1) if sent by overnight courier, two
         business days after mailing, and (2) if sent otherwise, upon delivery.

18.6     Survival of Terms. The provisions of ARTICLE 5 (Fees & Payment),
         Section 6.4 (Obligations on Termination), Section 10.2 (Rights
         Reserved), ARTICLE 11 (Restrictions on Use), Section 12.1 (Display of
         Marks, Legends & Notices), Section 14.1 (Limits on Liability), ARTICLE
         15 (Indemnification), ARTICLE 16 (Confidentiality), ARTICLE 17
         (Disputes), Section 18.6 (Survival of Terms) and Section 18.8
         (Governing Law), shall survive the termination of this Agreement for
         any reason.

18.7     Headings. The headings and subheadings used in this Agreement and in
         the Schedules hereto are only used for convenience of reference, and
         are not to be considered in construing this Agreement.

18.8     Governing Law. This Agreement shall be construed and governed by the
         substantive laws of the State of Illinois without giving effect to the
         conflict of laws provisions. The United Nations Convention of Contracts
         for the International Sale of Goods shall not apply to this Agreement.

18.9     Severability. If any provision of this Agreement is held to be invalid,
         illegal, or unenforceable, the remaining provisions hereof shall be
         unaffected thereby and remain valid and enforceable as if such
         provision had not been set forth herein. The parties agree to
         substitute for such provision a valid provision which most closely
         approximates the intent and economic effect of such severed provision.

18.10    Advice of Counsel. The parties acknowledge that prior to executing this
         Agreement they have been advised by legal counsel and fully understand
         and agree

         else in executing this Agreement that is not set forth expressly
         herein.

IN WITNESS WHEREOF, the parties have caused their duly authorized
representatives to execute this Agreement as of the Effective Date set forth in
