     Re:  Amendment to Note Purchase Agreements

Ladies and Gentlemen:

     Reference is made to (1) the Note Purchase Agreement, dated as of November
15, 2000, by and between Navigant International, Inc., a Delaware corporation
(the "Company"), and The Prudential Insurance Company of America, (2) the Note
Purchase Agreement, dated as of November 15, 2000, by and between the Company,
on the one hand, and Security Life of Denver Insurance Company, USG Annuity &
Life Company, Northern Life Insurance Company, Reliastar Life Insurance Company,
Reliastar Life Insurance Company of New York and Security Connecticut Life
Insurance Company, on the other hand, (3) the Note Purchase Agreement, dated as
of November 15, 2000, by and between the Company and Teachers Insurance and
Annuity Association of America, (4) the Note Purchase Agreement, dated as of
November 15, 2000, by and between the Company and The Guardian Life Insurance
Company of America, and (5) the Note Purchase Agreement, dated as of November
15, 2000, by and between the Company and Hartford Life Insurance Company (each a
"Note Purchase Agreement"; collectively, the "Note Purchase Agreements").
Capitalized terms not defined herein shall have the meanings given to such terms
in the Note Purchase Agreements.

     Pursuant to the request of the Company and the provisions of Section 17.1
of the Note Purchase Agreements, each of the undersigned agrees to amend the
respective Note Purchase Agreement to which it is a party, subject to the
conditions and in reliance on the representations and warranties set forth
herein.

     In consideration of the foregoing recitals, the parties hereto agree as
follows:

     1.   Amendments to Note Purchase Agreements.

          1.1  Section 10.5 of each Note Purchase Agreement is amended by
inserting the following proviso at the end thereof:

          "; provided, however, that solely during such period of time
          Consolidated EBITDA for the period of four fiscal quarters ended
          September 30, 2001 is

          relevant, the Company may permit such ratio to be in excess of
          2.75:1.00 but not greater than 3.75:1.00."

          1.2  The following is added to each Note Purchase Agreement as a new
Section 9.10 thereof:

          "9.10  Minimum Commitment.

          The Company shall at all times have in place a committed revolving
          credit facility from banks and other financial institutions with
          aggregate availability of not less than $150,000,000, and such
          facility shall not expire until such time as each holder of the Notes
          has received (i) financial statements of the Company and its
          subsidiaries for the fiscal year ended December 31, 2001 (which may be
          in the form of internally-prepared financial statements) and (ii) a
          certificate ("Certificate") from the Company's chief financial officer
          certifying to the effect that such financial statements fairly present
          in all material respects the consolidated financial position of the
          Company and its Restricted Subsidiaries as of December 31, 2001 and
          that no Default or Event of Default existed on December 31, 2001 or
          exists as of the date of the Certificate, unless such Default or Event
          of Default has been consented to or waived."

          1.3  The following is added to each Note Purchase Agreement as a new
Section 10.14 thereof:

          "10.14  Minimum Bank Commitment.

          The Company will not allow the principal amount of Indebtedness of the
          Company under the Bank Credit Agreement to be less than $100,000,000
          until such time as each holder of the Notes has received (i) financial
          statements of the Company and its subsidiaries for the fiscal year
          ended December 31, 2001 (which may be in the form of internally-
          prepared financial statements) and (ii) the Certificate."

          1.4  The following definition is added to the list of definitions set
forth on Schedule B of each Note Purchase Agreement, inserted in its respective
alphabetical sequence:

          "Certificate" shall have the meaning assigned to such term in Section
          9.10.

     2.   Condition to Effectiveness.  The effectiveness of the foregoing
amendments is subject to the receipt by each of the undersigned of an amendment
to the Bank Credit Agreement, in the form of Exhibit A attached hereto ("Bank
Amendment"), duly executed and
<PAGE>

delivered by each lender under the Bank Credit Agreement and Bank of America, as
agent thereunder (collectively, the "Bank Group").

     3.   Representations and Warranties.  The Company hereby certifies that (a)
no Default or Event of Default under any Note Purchase Agreement will exist upon
giving effect to this letter amendment and the Bank Amendment, and (b) the Bank
Group is not receiving any remuneration for the Bank Amendment.

     4.   Covenants of the Company.  In consideration of the consent set forth
above, the Company hereby covenants and agrees that, notwithstanding Section
10.9, Section 10.11, and Section 10.12 of, or any other provision to the
contrary in, the Note Purchase Agreements or the other Transaction Documents,
the Company will not at any time prior to the time each holder of the Notes has
received the Certificate (a) make any cash payments to acquire all or any
portion of the capital stock or other ownership interest in, or all or any
substantial portion of the assets, property and/or operations of, any Person
(except cash payments made to satisfy earn-out obligations to the extent
exclusively funded from the revenues of the acquired Person or from assets or
operations acquired from a Person shall not be prohibited hereunder) or (b) make
or permit any cash payments to repurchase or redeem any capital stock of the
Company, or (c) declare or pay any cash dividend or make any other cash
distribution on any of its capital stock now outstanding or hereafter issued.

     5.   No Waiver.  The amendments and agreements set forth in this letter
amendment shall be limited precisely as written and shall not be deemed to be
(a) an amendment, consent or waiver of any other terms or conditions of any Note
Purchase Agreement or any other Transaction Document, (b) a waiver of any right
or remedy of the holders of the Notes pursuant to the Transaction Documents or
(c) a consent to any future amendment, consent or waiver of any provision of the
Note Purchase Agreements or any other Transaction Document. Except as expressly
set forth in this letter amendment, each Note Purchase Agreement and all related
documents shall continue in full force and effect.

     6.   Counterparts; Effectiveness.  This letter amendment may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed an
original, but all of which counterparts together shall constitute but one and
the same instrument.
