AGREEMENT AND PLAN OF MERGER

This Agreement and Plan of Merger (this “Agreement”) is made and entered into as of the 26^thday of April, 2006, by and among ▇▇▇▇▇▇▇ Wagonlit B.V., a Dutch B.V. (“CWT”), Horizon Merger Corp., a Delaware corporation and a wholly owned subsidiary of CWT (“Merger Sub”), and Navigant International, Inc., a Delaware corporation (“Navigant”).

RECITALS

WHEREAS, CWT and Navigant desire that CWT combine its businesses with the businesses operated by Navigant through the merger of Merger Sub with and into Navigant, with Navigant as the surviving corporation (the “Merger”), pursuant to which each share of common stock of Navigant, par value $0.001 per share (“Navigant Common Stock”) issued and outstanding at the Effective Time (as defined in Section 1.2), other than the shares of Navigant Common Stock owned by CWT, Merger Sub or Navigant (or any of their respective direct or indirect wholly owned subsidiaries (as defined in Section 8.3)) and other than the Appraisal Shares (as defined in Section 2.1(d)), will be converted into the right to receive the Merger Consideration (as defined in Section 2.1(b)), all as more fully provided in this Agreement; and

WHEREAS, the board of directors (the “Board”) of each of CWT, Merger Sub and Navigant has determined that the Merger upon the terms and subject to the conditions set forth in this Agreement is advisable, fair to and in the best interests of their respective stockholders; and

WHEREAS, CWT, Merger Sub and Navigant desire to make those representations, warranties, covenants and agreements specified herein in connection with this Agreement.

NOW, THEREFORE, in consideration of the premises, and of the representations, warranties, covenants and agreements contained herein, CWT, Merger Sub and Navigant agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger. Upon the terms and subject to the conditions of this Agreement, and in accordance with the provisions of the Delaware General Corporation Law (the “DGCL”), Merger Sub shall be merged with and into Navigant at the Effective Time. As a result of the Merger, the separate corporate existence of Merger Sub shall cease and Navigant shall continue its existence as a wholly owned subsidiary of CWT under the laws of the State of Delaware. Navigant, in its capacity as the corporation surviving the Merger, is hereinafter sometimes referred to as the ”Surviving Corporation.”

1.2 Closing; Effective Time. A closing (the “Closing”) shall be held at the offices of Wachtell, Lipton, ▇▇▇▇▇ & ▇▇▇▇, ▇▇ ▇▇▇▇ ▇▇^▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇.▇. ▇▇▇▇▇, or such other place as the parties hereto may agree, as soon as practicable but no later than the second business day following the date upon which all conditions set forth in Article VI (other than

those conditions that by their nature are to be satisfied or waived at the Closing, but subject to the satisfaction or waiver of those conditions) are satisfied or waived, or at such other date as CWT and Navigant may agree (such date, the “Closing Date”). As promptly as possible on the Closing Date, the parties hereto shall cause the Merger to be consummated by filing with the Secretary of State of the State of Delaware (the “Delaware Secretary of State”) a certificate of merger (the “Certificate of Merger”) in such form as is required by and executed in accordance with Section 251 of the DGCL. The Merger shall become effective when the Certificate of Merger has been filed with the Delaware Secretary of State or at such later time as shall be agreed upon by CWT and Navigant and specified in the Certificate of Merger (the “Effective Time”).

1.3 Effects of the Merger. From and after the Effective Time, the Merger shall have the effects set forth in Section 259 of the DGCL.

1.4 Certificate of Incorporation and Bylaws. The Certificate of Merger shall provide that at the Effective Time, (a) the Surviving Corporation’s Certificate of Incorporation as in effect immediately prior to the Effective Time shall be amended as of the Effective Time to read in the form attached hereto as Exhibit A, and (b) the Surviving Corporation’s Bylaws as in effect immediately prior to the Effective Time shall be amended as of the Effective Time to read in the form attached hereto as Exhibit B; in each case, until amended in accordance with the DGCL, this Agreement and such certificate of incorporation or bylaws, as the case may be.

1.5 Directors and Officers of the Surviving Corporation. From and after the Effective Time, the officers of Navigant shall be the officers of the Surviving Corporation and the directors of Merger Sub shall be the directors of the Surviving Corporation, in each case, until their respective successors are duly elected and qualified.

1.6 Navigant Stockholders Meeting.

(a) As promptly as practicable following the date of this Agreement, Navigant shall, in accordance with all applicable laws, statutes, orders, rules, regulations, policies or guidelines promulgated, or judgments, decisions or orders entered by any Governmental Authority (as defined in Section 3.3(d)), in each case, to the extent applicable (collectively, “Applicable Laws”), and Navigant’s Amended and Restated Certificate of Incorporation as in effect on the date of this Agreement (the “Navigant Certificate”) and Navigant’s By-laws, as in effect on the date of this Agreement (the “Navigant Bylaws”), duly call, give notice of, convene and hold a meeting of the holders of shares of Navigant Common Stock (the “Navigant Stockholders”) to consider and vote upon approval of this Agreement and the Merger (the “Navigant Stockholders Meeting”). Subject to Section 5.3(b)(iii), Navigant shall ensure that the Navigant Stockholders Meeting is called, noticed, convened, held and conducted, and that all proxies solicited in connection with the Navigant Stockholders Meeting are solicited in compliance in all material respects with Applicable Laws.

(b) Navigant shall promptly prepare and file with the Securities and Exchange Commission (the “Commission”) a proxy statement (together with any amendments thereof or supplements thereto, the “Proxy Statement”) that meets the requirements of Applicable Laws to seek the approval of this Agreement and the Merger. CWT shall promptly furnish to Navigant

all information concerning it and its business as Navigant may reasonably request in connection with the preparation of the Proxy Statement and the solicitation of proxies. Navigant shall respond promptly to any comments made by the Commission with respect to the Proxy Statement and any preliminary version thereof filed by it and shall cause such Proxy Statement to be mailed to the Navigant Stockholders as promptly as reasonably practicable. Navigant shall promptly notify CWT of the receipt of any comments of the Commission with respect to the Proxy Statement and shall provide to CWT copies of any comments received from the Commission in connection with the Proxy Statement. CWT shall be provided an opportunity to review and comment on all filings with the Commission, including the Proxy Statement, and all mailings to the Navigant Stockholders in connection with the Merger, and Navigant shall give reasonable consideration to all comments proposed by CWT.

(c) The Navigant Board shall make the Navigant Board Recommendation (as defined in Section 4.22(c)). Subject to Section 5.3(b)(iii), the Navigant Board Recommendation shall be included in the Proxy Statement and the Navigant Board shall use its reasonable best efforts to solicit the approval of this Agreement and the Merger by the Navigant Stockholders. In the event that subsequent to the date of this Agreement, the Navigant Board determines after consultation with outside counsel that a failure to withdraw, modify or qualify the Navigant Board Recommendation in a manner adverse to CWT would be reasonably likely to result in a breach of its fiduciary duties under Applicable Law, the Navigant Board may so withdraw, modify or qualify the Navigant Board Recommendation; provided, however, that the Navigant Board may not recommend any Acquisition Proposal (as defined in Section 5.3(b)(vii)(A)) (other than this Agreement and the transactions contemplated hereby, including the Merger), except as specifically contemplated by, and in accordance with, Section 5.3(b)(iii); provided, further, however, that unless this Agreement is theretofore terminated, Navigant shall nevertheless submit this Agreement to the Navigant Stockholders for adoption at the Navigant Stockholders Meeting.

1.7 Additional Actions. If, at any time after the Effective Time, the Surviving Corporation shall consider or be advised that any further deeds, assignments or assurances in law or any other acts are necessary or desirable to (a) vest, perfect or confirm, of record or otherwise, in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of Navigant or (b) otherwise carry out the provisions of this Agreement, Navigant and its officers and directors shall be deemed to have granted to the Surviving Corporation an irrevocable power of attorney to execute and deliver all such deeds, assignments or assurances in law and to take all acts necessary, proper or desirable to vest, perfect or confirm title to and possession of such rights, properties or assets in the Surviving Corporation and otherwise to carry out the provisions of this Agreement, and the officers and directors of the Surviving Corporation are authorized in the name of Navigant or otherwise to take any and all such action.

ARTICLE II

CONVERSION OF SECURITIES

2.1 Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of CWT, Merger Sub or Navigant or their respective stockholders:

(a) Each share of common stock, $0.001 par value, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one fully paid and nonassessable share of common stock, $0.001 par value, of the Surviving Corporation. Such newly issued shares shall thereafter constitute all of the issued and outstanding Surviving Corporation capital stock.

(b) Subject to the other provisions of this Article II, each share of Navigant Common Stock issued and outstanding immediately prior to the Effective Time (excluding (i) any shares of Navigant Common Stock owned by Navigant (which shares shall be cancelled in accordance with Section 2.1(c)), (ii) any shares of Navigant Common Stock owned by CWT or any direct or indirect wholly owned subsidiary of Navigant or CWT (which shares shall remain outstanding except that the number of such shares owned by CWT or any such subsidiary shall be adjusted in the Merger to maintain the relative ownership percentages) and (iii) any shares of Navigant Common Stock owned by stockholders properly exercising appraisal rights pursuant to Section 262 of the DGCL (“Section 262”), as provided in Section 2.1(d)) shall be converted into and represent the right to receive $16.50 in cash, without interest (the “Merger Consideration”). At the Effective Time, all shares of Navigant Common Stock shall no longer be outstanding and automatically shall be cancelled and shall cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented such shares of Navigant Common Stock (a “Certificate”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration.

(c) Each share of Navigant capital stock held in the treasury of Navigant automatically shall be cancelled and retired and no payment shall be made in respect thereof.

(d) Notwithstanding anything in this Agreement to the contrary, the shares of Navigant Common Stock issued and outstanding immediately prior to the Effective Time that are held by any Navigant Stockholder that is entitled to demand and properly demands appraisal of shares of Navigant Common Stock pursuant to, and complies in all respects with, the provisions of Section 262 (the “Appraisal Shares”) shall not be converted into the right to receive the Merger Consideration as provided in Section 2.1(b), but, instead, such Navigant Stockholder shall be entitled to such rights (but only such rights) as are granted by Section 262. At the Effective Time, all Appraisal Shares shall no longer be outstanding and automatically shall be cancelled and shall cease to exist, and, except as otherwise provided by Applicable Laws, each holder of Appraisal Shares shall cease to have any rights with respect to the Appraisal Shares, other than such rights as are granted by Section 262. Notwithstanding the foregoing, if any such Navigant Stockholder shall fail to validly perfect or shall otherwise waive, withdraw or lose the right to appraisal under Section 262 or if a court of competent jurisdiction shall determine that such Navigant Stockholder is not entitled to the relief provided by Section 262, then the rights of such Navigant Stockholder under Section 262 shall cease, and such Appraisal Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive the Merger Consideration as provided in Section 2.1(b) without interest. Navigant shall give prompt notice to CWT of any demands for appraisal of any shares of Navigant Common Stock, and CWT shall have the opportunity to participate in all negotiations and proceedings with respect to such demands. Prior to the Effective Time, Navigant shall not, without the prior written consent of CWT, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing.

2.2 Surrender and Payment.

(a) Paying Agent; Exchange Fund. Prior to the Effective Time, for the benefit of the Navigant Stockholders, CWT shall designate, or shall cause to be designated (pursuant to an agreement in form and substance reasonably acceptable to CWT and Navigant), a bank or trust company reasonably acceptable to CWT and Navigant to act as agent for the payment of the Merger Consideration in respect of Certificates upon surrender of such Certificates in accordance with this Article II from time to time after the Effective Time (the “Paying Agent”). At the Effective Time, CWT shall deposit, or cause Merger Sub to deposit, with the Paying Agent cash in an amount sufficient for the payment of the aggregate Merger Consideration pursuant to Section 2.1(b) upon surrender of such Certificates (such cash, the “Exchange Fund”). The Paying Agent shall invest any cash included in the Exchange Fund, as directed by CWT, on a daily basis; provided that such investments shall be in obligations of or guaranteed by the United States of America or of any agency thereof and backed by the full faith and credit of the United States of America, in commercial paper obligations rated A-1 or P-1 or better by ▇▇▇▇▇’▇ Investors Service, Inc. or Standard & Poor’s Corporation, respectively, or in deposit accounts, certificates of deposit or banker’s acceptances of, repurchase or reverse repurchase agreements with, or Eurodollar time deposits purchased from, commercial banks with capital, surplus and undivided profits aggregating in excess of $500 million (based on the most recent financial statements of such bank which are then publicly available at the Commission or otherwise). Any portion of the Exchange Fund (including any interest and other income resulting from investments of the Exchange Fund) that remains undistributed to the Navigant Stockholders six months after the date of the mailing required by Section 2.2(b) shall be delivered to CWT, upon demand by CWT, and holders of Certificates that have not theretofore complied with this Section 2.2 shall thereafter look only to CWT for payment of any claim to the Merger Consideration. If any Certificates shall not have been surrendered prior to seven years after the Effective Time, any such cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by Applicable Laws, become the property of CWT, free and clear of all claims or interest of any person previously entitled thereto.

(b) Exchange Procedure. As promptly as practicable after the Effective Time, the Paying Agent shall mail to each holder of record of a Certificate (i) a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates held by such Navigant Stockholder shall pass, only upon proper delivery of the Certificates to the Paying Agent and shall be in such form and have such other customary provisions as CWT may reasonably specify), and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as may be appointed by CWT, together with such letter of transmittal, duly completed and validly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate shall be entitled to receive promptly in exchange therefor the amount of cash into which the shares of Navigant Common Stock formerly represented by the Certificate shall have been converted pursuant to Section 2.1(b), and the Certificate so surrendered shall be cancelled. In the event of a transfer of ownership of Navigant Common Stock that is not registered in the stock transfer books of Navigant, the proper amount of cash may be paid in exchange therefor to a person other than the person in whose name the Certificate so surrendered is registered if the Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person

requesting such payment shall pay any transfer or other Taxes (as defined in Section 4.13(c)) required by reason of the payment to a person other than the registered holder of the Certificate or establish to the satisfaction of CWT that the Tax has been paid or is not applicable. No interest shall be paid or shall accrue on the cash payable upon surrender of any Certificate.

(c) Stock Transfer Books. At the close of business on the day on which the Effective Time occurs, the stock transfer books of Navigant shall be closed, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Navigant Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Paying Agent for transfer or any other reason, they shall be cancelled and exchanged as provided in this Article II.

(d) No Liability. None of CWT, Merger Sub, Navigant or the Paying Agent shall be liable to any person in respect of any cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(e) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming a Certificate to be lost, stolen or destroyed and, if required by CWT or the Surviving Corporation, the posting by such person of a bond in such reasonable amount as CWT or the Surviving Corporation may reasonably direct as indemnity against any claim that may be made against it with respect to the Certificate, the Paying Agent shall pay in respect of the lost, stolen or destroyed Certificate the Merger Consideration.

(f) No Further Ownership Rights in Navigant Common Stock. The Merger Consideration paid in accordance with the terms of this Article II in respect of Certificates that have been surrendered in accordance with the terms of this Agreement shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Navigant Common Stock represented thereby.

(g) Withholding Rights. Each of the Surviving Corporation and CWT shall be entitled to deduct and withhold, or cause the Paying Agent to deduct and withhold, from the consideration otherwise payable pursuant to this Agreement to any Navigant Stockholders or any holder of Navigant Options (as defined in Section 2.3(a)) such amounts as it may be required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”), or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by the Surviving Corporation, CWT or the Paying Agent, as the case may be, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Navigant Stockholders or holders of Navigant Options (as applicable) in respect of which the deduction and withholding was made by the Surviving Corporation, CWT or the Paying Agent, as the case may be. At or prior to the Effective Time, Navigant shall deliver to CWT a duly executed and acknowledged affidavit of Navigant, in form and substance reasonably satisfactory to CWT and in accordance with Treasury Regulation Section 1.1445-2(c)(3), 1.897-2(g) and 1.897-2(h), certifying that each “interest” in Navigant (within the meaning of Section 897(c)(1) of the Code) is not a “United States real property interest” within the meaning of Section 897(c) of the Code.

2.3 Treatment of Stock Options.

(a) At the Effective Time, each option to purchase a share of Navigant Common Stock (a “Navigant Option”) granted under the Navigant equity compensation plans in effect on the date of this Agreement (the “Navigant Stock Plans”), or otherwise, that is outstanding immediately prior to the Effective Time shall (i) if unvested, become fully vested and (ii) be converted into the right to receive (as soon as practicable following the Effective Time) an amount in cash (less any applicable withholding Taxes and without interest) equal to the product of (x) the excess, if any, of (A) the Merger Consideration over (B) the per share exercise price of Navigant Common Stock subject to such Navigant Option and (y) the number of shares of Navigant Common Stock subject to such Navigant Option immediately prior to the Effective Time. Each outstanding Navigant Option so converted shall, simultaneously with such conversion, be terminated. For the avoidance of doubt, the holder of each Navigant Option so terminated with an exercise price per share of Navigant Common Stock that is equal to or greater than the Merger Consideration shall not be entitled to receive any cash from the Surviving Corporation or CWT. Prior to the Effective Time, Navigant shall take any and all actions necessary to effectuate this Section 2.3(a).

(b) Navigant shall ensure that following the Effective Time no holder of a Navigant Option or any participant in any Navigant Stock Plan or other employee benefit arrangement of Navigant shall have any right thereunder to acquire any capital stock (including any “phantom” stock or stock appreciation rights) of Navigant or the Surviving Corporation. Prior to the Effective Time, Navigant shall deliver to the holders of Navigant Options appropriate notices, in form and substance reasonably acceptable to CWT, setting forth such holders’ rights pursuant to this Agreement.

2.4 Adjustments to Prevent Dilution. In the event that Navigant changes the number of shares of Navigant Common Stock, or securities convertible or exchangeable into or exercisable for shares of Navigant Common Stock, issued and outstanding prior to the Effective Time as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer, or other similar transaction, the Merger Consideration shall be equitably adjusted to reflect such change.

The Navigant SEC Documents, including any financial statements or schedules included in the Navigant SEC Documents, at the time filed (and, in the case of registration statements and proxy statements, on the dates of effectiveness and the dates of mailing, respectively) or, in the case of any Navigant SEC Document amended or superseded by a filing prior to the date of this Agreement, then solely on the date of such amending or superseding filing, (i) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, and (ii) complied in all material respects with the applicable requirements of the Exchange Act and the Securities Act, as the case may be. The financial statements of Navigant and its subsidiaries included in the Navigant SEC Documents (i) have been prepared from, and are in accordance with, the books and records of Navigant and its subsidiaries, (ii) at the time filed (and, in the case of registration statements and proxy statements, on the dates of effectiveness and the dates of mailing, respectively) or, in the case of any Navigant SEC Document amended or superseded by a filing prior to the date of this Agreement, then solely on the date of such amending or superseding filing, complied as to form in all material respects with the applicable accounting requirements and with the published rules and regulations of the Commission with respect thereto, (iii) were prepared in accordance with United States generally accepted accounting principles (“GAAP”) applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto, or, in the case of unaudited statements, as permitted by Form 10-Q of the Commission), and (iv) fairly present (subject, in the case of unaudited statements, to normal, recurring audit adjustments) the consolidated financial position of Navigant and its consolidated subsidiaries as at the dates thereof and the consolidated results of their operations and cash flows (and changes in financial position, if any) for the periods then ended.

respects the financial condition and results of operations of Navigant as of, and for, the periods presented in the Navigant SEC Documents. Since March 31, 2003, Navigant’s principal executive officer and its principal financial officer have disclosed to Navigant’s auditors and the audit committee of the Navigant Board (i) all significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting which are reasonably likely to adversely affect Navigant’s ability to record, process, summarize and report financial information and have identified for Navigant’s auditors any material weaknesses in internal controls and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in Navigant’s internal controls over financial reporting and Navigant has provided to CWT copies of any written materials relating to the foregoing. Navigant has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act); such disclosure controls and procedures are designed to ensure that material information relating to Navigant, including its consolidated subsidiaries, is made known to Navigant’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared, and, to the knowledge of Navigant, such disclosure controls and procedures are effective to ensure that all material information required to be included in Navigant’s periodic reports required under the Exchange Act is made known on a timely basis to the individuals responsible for filing the Navigant SEC Documents. Except as set forth in Section 4.7(b) to the Navigant Disclosure Schedule, there are no outstanding loans made by Navigant or any of its subsidiaries to any executive officer (as defined in Rule 3b-7 under the Exchange Act) or director of Navigant.

The representation contained in the immediately preceding sentence will not apply to statements or omissions included in the Proxy Statement based upon information furnished to Navigant by CWT or Merger Sub specifically for use therein. The Proxy Statement will comply as to form in all material respects with the provisions of the Exchange Act.

4.10 Compliance with Law. Navigant and its subsidiaries hold all franchises, grants, authorizations, licenses, permits, easements, variances, exemptions, consents, certificates,

approvals and orders of all Governmental Authorities necessary for the lawful conduct of their respective businesses (the “Navigant Permits”), except for failures to hold such Navigant Permits that would not, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect on Navigant. Navigant and its subsidiaries are in compliance with the terms of the Navigant Permits, except where the failure so to comply would not, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect on Navigant. The businesses of Navigant and its subsidiaries are not being conducted in violation of any Applicable Law, except for violations that would not, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect on Navigant. Except as set forth in Section 4.10 to the Navigant Disclosure Schedule, no investigation or review by any Governmental Authority with respect to Navigant or any of its subsidiaries is pending or, to the knowledge of Navigant, threatened, nor has any Governmental Authority indicated in writing an intention to conduct any such investigation or review, other than, in each case, those the outcome of which would not, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect on Navigant.

4.11 Litigation. There is no suit, claim, action, proceeding, hearing, notice of violation, demand letter or, to the knowledge of Navigant, investigation (each, an “Action”) pending, or, to the knowledge of Navigant, threatened, against Navigant or any of its subsidiaries or any executive officer or director of Navigant or any of its subsidiaries that would, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect on Navigant. Neither Navigant nor any of its subsidiaries is subject to any outstanding order, writ, injunction or decree that would, individually or in the aggregate, insofar as can be reasonably foreseen, have or reasonably be expected to have a Material Adverse Effect on Navigant.

(b) There has not been any action taken by Navigant or any of its subsidiaries from December 25, 2005 through the date of this Agreement that, if taken during the period from the date of this Agreement through the Effective Time, would constitute a breach of Section 5.3(a).

4.13 Taxes.

(a) Navigant and each of its subsidiaries has filed all material Tax Returns (as defined in Section 4.13(b)) required to be filed by it. All such Tax Returns were true, correct and complete in all material respects, and Navigant and each of its subsidiaries has paid or caused to be paid all material Taxes in respect of the periods covered by such Tax Returns other than Taxes for which appropriate reserves have been established in accordance with GAAP. Each of Navigant and its subsidiaries has timely withheld and paid all material Taxes required to have been withheld and paid in connection with amounts paid or owing to any employee, creditor, independent contractor, shareholder or other third party. Neither Navigant nor any of its subsidiaries is currently the beneficiary of any extension of time within which to file any

material Tax Return. There are no material security interests on any of the assets of Navigant or any of its subsidiaries that arose in connection with any failure to pay any Tax when due (taking into account relevant extensions), except with respect to such Taxes that are being contested in good faith by appropriate proceedings and for which appropriate reserves have been established in accordance with GAAP.

ARTICLE V

COVENANTS OF THE PARTIES

The parties hereto agree that:

5.1 Mutual Covenants.

(a) Reasonable Best Efforts.

(i) Subject to the terms and conditions of this Agreement, each party hereto will use its reasonable best efforts to take, or cause to be taken, promptly all actions, and to do, or cause to be done, promptly all things necessary, proper or advisable under this Agreement and Applicable Laws to consummate the Merger and the other transactions contemplated by this Agreement as soon as practicable after the date hereof, including preparing and filing as promptly as practicable all documentation to effect all necessary applications, notices, petitions, filings, and other documents, and to obtain as promptly as practicable (A) all consents, waivers, licenses, novations, orders, registrations, approvals, permits, rulings, authorizations and clearances necessary or advisable to be obtained from any Governmental Authority in order to consummate the Merger or any of the other transactions contemplated by this Agreement (collectively, the “Required Approvals”), and (B) the consents and authorizations of the third parties identified in Section 5.1(a) of the Navigant Disclosure Schedule. In furtherance and not in limitation of the foregoing, each of Navigant and CWT agrees to make (1) as promptly as practicable, but in any event within ten business days, an

appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby, and (2) as promptly as practicable all other necessary filings with other Governmental Authorities relating to the Merger, and to supply as promptly as practicable any additional information or documentary material that may be requested pursuant to such laws or by such authorities and to use reasonable best efforts to cause the expiration or termination of the applicable waiting periods under the HSR Act and the receipt of Required Approvals under such other laws or from such authorities as promptly as practicable. Each party shall have responsibility for its respective filing fees associated with the filings under the HSR Act and other Required Approvals. Notwithstanding anything to the contrary in this Agreement, neither Navigant nor CWT nor any of their respective subsidiaries shall be required (x) to hold separate (including by trust or otherwise) or to divest any of their respective businesses or assets, or (y) to accept any operational restriction, or take any other action that, in the reasonable judgment of CWT, could be expected to limit the right of CWT or Navigant to own or operate all or any portion of their respective businesses or assets.

(ii) Each of CWT and Navigant shall, in connection with the efforts referenced in Section 5.1(a)(i) to obtain all Required Approvals, use its reasonable best efforts, but in any event subject to Applicable Laws, to (A) cooperate in all respects with each other in connection with any filing or submission and in connection with any investigation or other inquiry, including any proceeding initiated by a private party, (B) subject to Applicable Laws, permit counsel for the other party to review in advance any proposed written communication between it and any Governmental Authority; provided, however, that the parties may redact any information (1) regarding the Merger Consideration, (2) alternative mergers or acquisitions considered, (3) that is privileged and the provision of which to the other party would waive such privilege, or (4) that would violate a confidentiality agreement with a third party, (C) promptly inform each other of (and, at the other party’s reasonable request, supply to such other party’s counsel) any communication (or other correspondence or memoranda) received by such party from, or given by such party to, the Department of Justice (“DOJ”), the Federal Trade Commission (“FTC”) or any other Governmental Authority and of any material communication received or given in connection with any proceeding by a private party, in each case regarding any of the transactions contemplated hereby, (D) consult with each other in advance to the extent practicable of any meeting or conference with the DOJ, the FTC or any other Governmental Authority or, in connection with any proceeding by a private party, with any other Person, and to the extent permitted by the DOJ, the FTC or such other applicable Governmental Authority or other Person, give the other party the opportunity to attend and participate in such meetings and conferences, and (E) keep each other apprised of the status of any filings or any requests for additional information and documentary material.

(iii) In furtherance and not in limitation of the covenants of the parties contained in Sections 5.1(a)(i) and 5.1(a)(ii), if any administrative or judicial action or proceeding, including any proceeding by a private party, is instituted (or threatened to be instituted) challenging any transaction contemplated by this Agreement as violative of any regulatory law, or if any statute, rule, regulation, executive order, decree, injunction or administrative order is enacted, entered, promulgated or enforced by a Governmental Authority which would make the Merger or the other transactions contemplated hereby illegal or would otherwise prohibit or materially impair or delay the consummation of the Merger or the other transactions contemplated hereby, each of CWT and Navigant shall cooperate in all respects with

each other and use its respective reasonable best efforts, to contest and resist vigorously any such action or proceeding and to seek to avoid the entry of, or seek to have vacated, lifted, reversed or overturned as promptly as practicable, any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the Merger or the other transactions contemplated by this Agreement on or before the Termination Date and to seek to have such statute, rule, regulation, executive order, decree, injunction or administrative order repealed, rescinded or made inapplicable as promptly as practicable so as to permit consummation of the transactions contemplated by this Agreement on or before the Termination Date. Notwithstanding the foregoing or any other provision of this Agreement, nothing in this Section 5.1(a) shall limit a party’s right to terminate this Agreement pursuant Article VII so long as such party has up to then complied with its obligations under this Section 5.1(a).

(iv) In the event a party hereto receives a request for additional information or documentary material (“Second Request”) issued by a Governmental Authority pursuant to 16 C.F.R. § 803.20 in connection with the transactions contemplated by this Agreement, such party will comply with such request as provided by Section 7A(e) of the HSR Act as quickly as practicable. In the event that a party hereto receives a subpoena or civil investigative demand requesting materials and information similar to that usually demanded in a Second Request, such party shall comply with such subpoena or civil investigative demand as quickly as practicable. In the event the Governmental Authority disputes the adequacy of compliance by a party hereto with respect to a Second Request, subpoena, or civil investigative demand, such party shall endeavor to satisfy the Governmental Authority so as to minimize any delay in the conduct or resolution of the investigation. Each of the Parties agrees that, during the term of this Agreement, it will not withdraw its filing under the HSR Act or any other applicable antitrust, competition or trade regulation law without the written consent of the other party. Each of the Parties agrees that it will not enter into any timing agreement with any Governmental Authority without the written consent of the other party.

(b) Public Announcements. CWT and Navigant will consult with each other before issuing any press release or making any public statement with respect to this Agreement or the transactions contemplated hereby and, except as may be required by Applicable Law or any listing agreement with any national securities exchange, will not issue any such press release or make any such public statement prior to such consultation.

(c) Conveyance Taxes. Navigant and CWT shall cooperate in the preparation, execution and filing of all Tax Returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer and stamp taxes, any transfer, recording, registration and other fees, and any similar Taxes that become payable in connection with the transactions contemplated by this Agreement that are required or permitted to be filed on or before the Effective Time.

(d) Notice of Certain Events. Each of the Navigant and CWT shall promptly notify the other of:

(i) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement;

(ii) any material notice or other communication from any Governmental Authority in connection with the transactions contemplated by this Agreement; and

(iii) any actions, suits, claims, investigations or proceedings commenced after the date hereof or, to its knowledge, threatened after the date hereof against, relating to or involving or otherwise affecting Navigant, CWT or any of their respective subsidiaries that relate to the consummation of the transactions contemplated by this Agreement, including the Merger.

5.2 Covenants of CWT.

(a) Indemnification; Directors’ and Officers’ Insurance.

(i) For a period of six years from the Effective Time, the Surviving Corporation’s Certificate of Incorporation and the Surviving Corporation’s Bylaws shall contain provisions no less favorable with respect to indemnification than are set forth in Article Eight of the Navigant Certificate and Article IV of the Navigant Bylaws, in each case as in effect on the date hereof, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Effective Time, were directors or officers of Navigant or any of its subsidiaries, unless such modification shall be required by law and then only to the minimum extent required by law.

(ii) After the Effective Time, for a period of six years after the date thereof, CWT shall cause the Surviving Corporation to, and the Surviving Corporation shall, to the fullest extent permitted under applicable law, indemnify and hold harmless, each present and former director or officer of Navigant and each of its subsidiaries (individually, an “Indemnified Party” and collectively, the “Indemnified Parties”) against all costs and expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages, liabilities and settlement amounts paid in connection with any claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), whether civil, criminal, administrative or investigative, arising out of or pertaining to any action or omission occurring at or prior to the Effective Time in their capacity as an officer or director. If the Surviving Corporation acknowledges its indemnification obligations under this Section 5.2, the Surviving Corporation shall be entitled to assume the defense of any such action, suit, proceeding or investigation and, if the Surviving Corporation assumes the defense thereof, the Surviving Corporation shall not be liable to any Indemnified Party for any legal expenses of separate counsel or any other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof, except that if the Surviving Corporation elects not to assume such defense or counsel to the Indemnified Party advises that there are issues that raise conflicts of interest between the Surviving Corporation and the Indemnified Party, the Indemnified Party may retain counsel reasonably satisfactory to the Surviving Corporation, and the Surviving Corporation shall pay all reasonable

fees and expenses of such counsel for the Indemnified Party promptly as statements therefor are received; provided that the Surviving Corporation shall not be liable for the fees of more than one counsel for all Indemnified Parties, other than local counsel, unless a conflict of interest shall be caused thereby, and provided further that the Surviving Corporation shall not be liable for any settlement effected without its written consent (which consent shall not be unreasonably withheld or delayed). If the Surviving Corporation does not assume the defense of any such action, suit, proceeding or investigation, the Surviving Corporation shall reasonably cooperate with the Indemnified Parties in the defense of any such matter and shall permit the Indemnified Parties and their counsel and other authorized representatives reasonable access during normal business hours to the offices, properties, books and records (including, without limitation, pertinent and necessary financial documents, internal correspondence, notes, memoranda, and electronic mail) and personnel of the Surviving Corporation and its subsidiaries for the purposes of responding to, defending against or otherwise dealing with any such matter.

(iii) CWT shall cause the Surviving Corporation or CWT to obtain and maintain in effect, for a period of six years after the Effective Time, policies of directors’ and officers’ liability insurance on behalf of the former officers and directors of Navigant currently covered by Navigant’s directors’ and officers’ liability insurance policy with respect to acts or omissions occurring prior to the Effective Time with at least the same coverage and containing terms and conditions that are not less favorable than those under existing policies; provided, however, that if the aggregate annual premiums for such insurance at any time during such period shall exceed 200% of the per annum rate of premium paid by Navigant and its subsidiaries as of the date hereof for such insurance, then CWT shall or shall cause its subsidiaries to, provide only such coverage as shall then be available at an annual premium equal to 200% of such rate.

(iv) In the event the Surviving Corporation or any of its successors or assigns (A) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (B) transfers all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation, or at CWT’s option, CWT, shall assume the obligations set forth in this Section 5.2(a).

(v) The provisions of this Section 5.2(a) are intended to be for the benefit of, and will be enforceable by, each Indemnified Party, his or her heirs and his or her representatives and (ii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by contract or otherwise.

(vi) CWT shall cause the Surviving Corporation to perform all of the obligations of the Surviving Corporation under this Section 5.2(a).

(b) Employees and Employee Benefits.

(i) CWT will cause the Surviving Corporation to honor the obligations of Navigant and any of its subsidiaries as of the Effective Time under the provisions of all Plans listed on Section 4.15(b) of the Navigant Disclosure Schedule, provided that this provision shall not prevent the Surviving Corporation from amending, suspending or terminating

any such Plans to the extent permitted by the applicable terms of such Plan. Notwithstanding any such amendment, suspension or termination, CWT shall, following the Effective Time and until December 31, 2006, cause the Surviving Corporation and its subsidiaries to provide Navigant Employees with a comprehensive employee benefits program (excluding equity incentives) substantially similar in the aggregate to employee benefits currently provided to Navigant Employees, it being understood that this Section 5.3(b)(i) shall not prevent CWT or the Surviving Corporation from changing any specific employee benefits program or provision other than the United Healthcare Insurance Company Personal Benefit Account Plan. Subject to the accuracy of the representation in Section 4.15(l), CWT shall, following the Effective Time and until December 31, 2006, cause the Surviving Corporation and its subsidiaries either to maintain, or to provide a plan or program substantially equivalent to, the United Healthcare Insurance Company Personal Benefit Account Plan, for the benefit of participants in that plan as of the date hereof; provided, however, that no termination or modification of the United Healthcare Insurance Company Personal Benefit Account Plan prior to December 31, 2006 will result in any financial or material detriment to a plan participant.

(ii) Nothing contained in this Agreement shall restrict the ability of CWT and its affiliates to terminate the employment of any Navigant Employee for any reason at any time after the Effective Time.

(iii) For purposes of this Section 5.2(b), “Navigant Employees” means individuals who are, as of the Effective Time, employees of Navigant and its subsidiaries not subject to collective bargaining agreements and who following the Effective Time continue such employment with Navigant, CWT or their respective subsidiaries.

(iv) With respect to benefit plans of CWT in which Navigant Employees (and their dependents) participate after the Closing Date, CWT shall (and shall cause the Surviving Corporation to): (A) waive any limitations as to pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to Navigant Employees under any such plan in which such Navigant Employees may be eligible to participate after the Closing Date; provided, however, that no such waiver shall apply to (1) a pre-existing condition of any Navigant Employee or any dependent thereof, who was, immediately prior to the Closing Date, excluded from participation in a benefit plan maintained or contributed to for the benefit of such Navigant Employee or dependent by nature of such pre-existing condition or (2) any Navigant Employee or any dependent thereof, who did not, immediately prior to the Closing Date participate in the applicable Navigant plan, (B) provide each Navigant Employee with credit for any co-payments and deductibles paid prior to the Closing Date during the year in which the Closing Date occurs in satisfying any applicable deductible or out-of-pocket requirements under any welfare benefit plan in which such Navigant Employee may be eligible to participate after the Closing Date, and (C) recognize all service of Navigant Employees with Navigant or any affiliate (including, without limitation, Navigant subsidiaries) or predecessor(s) thereof for purposes of eligibility to participate, vesting credit, entitlement to benefits and benefit accrual (but not for purposes of benefit accrual under any CWT plans other than vacation and severance benefits) in any benefit plan in which such Navigant Employee may be eligible to participate on or after the Closing Date, except to the extent such treatment would result in duplicative benefits, benefit accrual under a defined benefit

plan or past credited service that is not provided for other participants in such benefit plan generally.

(c) Supplemental Indenture. As of the Effective Time, the Surviving Corporation and CWT shall (i) execute and deliver to ▇▇▇▇▇ Fargo Bank, National Association (successor by merger to ▇▇▇▇▇ Fargo Bank Minnesota, N.A.), as trustee under the Indenture, dated as of November 7, 2003, between Navigant, as issuer, and ▇▇▇▇▇ Fargo Bank, National Association (successor by merger to ▇▇▇▇▇ Fargo Bank Minnesota, N.A.), as trustee, as amended by the First Supplemental Indenture dated as of July 22, 2005 (as amended, the ”Indenture”), a supplemental indenture in accordance with Section 12.01 and Section 15.06 of the Indenture.

(d) Financing. Each of CWT and Merger Sub shall use its reasonable best efforts to obtain the funding contemplated by each of the Financing Letters on terms and conditions no less favorable to CWT and Merger Sub than the terms set forth in the Financing Letters. In the event that at any time funds are not or have not been made available pursuant to any of the Financing Letters, each of CWT and Merger Sub shall use its reasonable best efforts to obtain alternative funding in an amount at least equal to the amount necessary to consummate the Merger; provided, however, that CWT and Merger Sub shall not be obligated to obtain alternative financing other than alternative financing (in an amount no less than the amounts specified in the Debt Commitment Letters) from a globally recognized banking and lending institution on terms and conditions substantially similar to the terms and conditions contained in the Debt Commitment Letters. Following the date hereof, (i) CWT and Merger Sub shall not agree to any amendment or modification of any term or condition of any of the Financings without the prior written consent of Navigant (such consent not to be unreasonably withheld or delayed) if such amendment or modification would reasonably be expected to prevent or materially delay consummation of the transactions contemplated by this Agreement or any of the Financings and (ii) CWT shall disclose promptly to Navigant any termination or cancellation of any of the Financings and any information that becomes known to CWT or Merger Sub regarding any facts or circumstances that would reasonably be expected to prevent or materially delay any of the Financings or consummation of the transactions contemplated by this Agreement.

(iii) Notwithstanding anything in this Agreement to the contrary, nothing contained in this Agreement shall prevent Navigant or the Navigant Board from at any time prior to, but not after, the time this Agreement and the Merger are approved by the Navigant Stockholders at the Navigant Stockholders Meeting, (A) providing information in response to a request therefor by, or engaging in any negotiations or discussions with, a Person who has made a bona fide written Acquisition Proposal to the Navigant Board after the date hereof which was not solicited by Navigant, directly or indirectly, after the date hereof in violation of Section 5.3(b)(i) if the Navigant Board receives from such Person an executed confidentiality agreement on customary terms no less favorable to Navigant than the Confidentiality Agreement, dated as of March 31, 2005, between Navigant and CWT (the ”Confidentiality Agreement”); or (B) recommending such an unsolicited bona fide written Acquisition Proposal to the Navigant Stockholders, if and only to the extent that, (1) in each such case referred to in clause (A) or (B) above, the Navigant Board determines in good faith after consultation with outside legal counsel that a failure to take such action would be reasonably likely to result in a breach by its directors of their respective fiduciary duties under Applicable Law, (2) in the case of clause (A) above, the Navigant Board determines in good faith after consultation with outside legal counsel and outside financial advisors that there is a reasonable likelihood that such Acquisition Proposal will result in a Superior Proposal; and (3) in the case of clause (B) above, the Navigant Board determines in good faith that such Acquisition Proposal (in the form, other than immaterial changes, that was the subject of the Superior Proposal Notice, as defined below) constitutes a

Superior Proposal and CWT shall have received written notice (the ”Superior Proposal Notice”) of Navigant’s intention to take the action referred to in clause (B) at least seventy-two (72) hours prior to the taking of such action by Navigant (the ”Waiting Period”); provided, however, that the Navigant Board continues to believe, after taking into account any modifications to the terms of the transaction contemplated by this Agreement that are proposed by CWT after its receipt of the Superior Proposal Notice (with respect to which modifications Navigant and CWT shall endeavor to negotiate in good faith), that such Acquisition Proposal constitutes a Superior Proposal. If the Navigant Board recommends an unsolicited bona fide written Acquisition Proposal pursuant to clause (B) above, then CWT shall be entitled to terminate this Agreement pursuant to Section 7.4(a) of the Agreement.

(iv) Navigant agrees that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any Person (other than the parties hereto) conducted heretofore with respect to any Acquisition Proposal. Navigant agrees that it will take the necessary steps to promptly inform the officers, directors, employees and Representatives of Navigant and its subsidiaries of the obligations undertaken in this Section 5.3(b). Navigant also agrees promptly, but, in any event, within five days after the date of this Agreement, to request the return or destruction of all confidential information and materials provided prior to the date of this Agreement by it, its subsidiaries or their respective Representatives to any Person (other than the parties hereto) that has executed a confidentiality agreement within the last twelve (12) months prior to the date hereof in connection with its consideration or making of any Acquisition Proposal.

(v) From and after the execution of this Agreement, Navigant shall promptly, orally notify CWT of any request for information or any inquiries, proposals or offers relating to an Acquisition Proposal indicating, in connection with such notice, the name of such Person making such request, inquiry, proposal or offer and the material terms and conditions of any proposals or offers and Navigant shall provide to CWT written notice of any such inquiry, proposal or offer within 24 hours of such event. Navigant shall keep CWT informed orally on a reasonably current basis of the status of any Acquisition Proposal, including with respect to the status and material terms of any such proposal or offer and whether any such proposal or offer has been definitively withdrawn or rejected. Navigant also agrees to provide to CWT any material non-public information regarding Navigant (not theretofore provided or made available to CWT) that it is providing to another Person pursuant to this Section 5.3(b)(v) promptly after it provides such information to such other Person.

(vi) Without limiting the foregoing, it is understood that any violation of the restrictions set forth in this Section 5.3(b) by any officer, director or employee of Navigant or any of its subsidiaries or any Representative of Navigant or any of its subsidiaries shall be deemed to be a breach of this Section 5.3(b) by Navigant.

(vii) For purposes of this Agreement:

(A) “Acquisition Proposal” means any proposal or offer with respect to (1) a merger, reorganization, share exchange, consolidation, business combination, recapitalization, dissolution, liquidation or similar transaction involving Navigant, (2) any purchase of an equity interest (including by means of

a tender or exchange offer) representing an amount equal to or greater than a 15% voting or economic interest in Navigant, or (3) any purchase of assets, securities or ownership interests representing an amount equal to or greater than 15% of the consolidated assets of Navigant and its subsidiaries taken as a whole (including stock of the subsidiaries of Navigant).

(B) “Superior Proposal” means a bona fide written Acquisition Proposal (except that references in the definition of “Acquisition Proposal” to “15%” shall be replaced by “50%”) made by a Person other than a party hereto that is on terms that the Navigant Board (after consultation with its outside financial advisor and outside counsel) in good faith concludes, taking into account, among other relevant considerations, all legal, financial, regulatory and other aspects of the proposal, the likelihood of obtaining financing and satisfying other conditions, and the Person making the proposal, are more favorable to the Navigant Stockholders than the transaction contemplated by this Agreement, taking into account any change in the transaction proposed by CWT.

(c) Third Party Standstill Agreements. During the period from the date of this Agreement until the earlier of the Effective Time and termination of this Agreement: (i) Navigant shall not (and shall not agree to, and shall not permit any of its subsidiaries to or to agree to) terminate, amend, modify or waive any provision of any confidentiality or standstill agreement to which it or any of its subsidiaries is a party (other than any involving CWT or its subsidiaries); and (ii) Navigant shall use its commercially reasonable efforts to enforce, to the fullest extent permitted under Applicable Law, the provisions of any such agreements, including, if so requested by CWT and at CWT’s expense, seeking injunctions to prevent any breaches of such confidentiality or standstill agreements and enforcing specifically the terms and provisions thereof in any court of the United States or any state thereof having jurisdiction.

(d) Access. From the date hereof until the Effective Time and subject to Applicable Law and the Confidentiality Agreement, Navigant shall (i) give CWT, its counsel, financial advisors, auditors and other authorized representatives reasonable access during normal business hours to the offices, properties, books and records of Navigant and its subsidiaries, (ii) furnish to CWT, its counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information as such Persons may reasonably request (including furnishing to CWT Navigant’s financial results in advance of filing any Navigant SEC Documents containing such financial results), and (iii) instruct the employees, counsel, financial advisors, auditors and other authorized representatives of Navigant and its subsidiaries to cooperate with CWT in its investigation of Navigant and its subsidiaries. Any investigation pursuant to this Section 5.3(d) shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of Navigant and its subsidiaries. No information or knowledge obtained by CWT in any investigation pursuant to this Section shall affect or be deemed to modify any representation or warranty made by Navigant hereunder.

(e) Convertible Debentures. Navigant shall provide the notice required pursuant to Section 15.01(b)(ii) of the Indenture.

(f) Financing Matters. Navigant will provide CWT and Merger Sub and its financing sources as promptly as practicable (i) the consolidated annual audited accounts of Navigant (which shall be provided within 90 days of the financial year end), (ii) the unaudited consolidated quarterly financial statements of Navigant (which shall be provided within 45 days of the end of each financial quarter) and (iii) such other reasonable financial information as may be reasonably requested from time to time. Navigant shall, and shall cause its Subsidiaries to, provide such reasonable cooperation as may be reasonably requested by CWT and Merger Sub in connection with the Financings, including (i) upon reasonable advance notice by CWT and Merger Sub, participation in meetings, drafting sessions, due diligence sessions, management presentation sessions, “road shows” and sessions with rating agencies; (ii) using its reasonable best efforts in satisfying the conditions in the Acquisition Commitment Letter that require action by Navigant or its subsidiaries; (iii) using its reasonable best efforts in providing and executing customary documents as may reasonably be requested by CWT and Merger Sub or such financing sources, including a certificate of the Chief Financial Officer of Navigant with respect to solvency matters; (iv) using its reasonable best efforts in obtaining accountants’ comfort letters, accountants’ consents for use of their reports in materials relating to the debt financing, legal opinions, surveys and title insurance as may be reasonably requested by CWT and Merger Sub; (v) reasonably cooperating with CWT in preparing offering memoranda, private placement memoranda, prospectuses and similar documents (including any materials for rating agency presentations); (vi) reasonably cooperating with the marketing efforts of CWT and Merger Sub and its financing sources for any debt; and (vi) forming new direct or indirect Subsidiaries.

8.3 Interpretation. When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article or Section of this Agreement unless otherwise indicated. The headings, the table of contents and the index of defined terms contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes,” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” Information disclosed in one section of the Navigant Disclosure Schedule shall be integrated into

another section of the Navigant Disclosure Schedule without the necessity of a cross-reference to the extent its applicability thereto is readily apparent. For the purposes of this Agreement:

(a) “Material Adverse Effect” with respect to Navigant means any event, change, circumstance or effect (any such item, an ”Effect”) that is or is reasonably likely to have a material adverse effect on the business, results of operations or financial condition of Navigant and its subsidiaries taken as a whole or on its ability to perform its obligations under this Agreement on a timely basis or to consummate the transactions contemplated by this Agreement on a timely basis; provided, however, that in no event shall any of the following be deemed, either alone or in combination, to constitute, nor shall any of the following be taken into account in determining whether there has been, a Material Adverse Effect with respect to Navigant: (i) any Effect related to the actions of CWT or Merger Sub or the public announcement or pendency of the transactions contemplated by this Agreement, (ii) any Effect that results from (x) any action taken pursuant to or in accordance with this Agreement or (y) any action taken, or any failure to take action, to which CWT has consented in writing, (iii) any change, in and of itself, in the market price or trading volume of shares of Navigant, or (iv) any Effect that results from changes in general economic conditions or general changes in the travel industry (including economic, legal or regulatory changes or circumstances that affect or are generally perceived to affect traveler health or safety, or any material worsening of terrorist activities or war or armed hostilities occurring after the date hereof), except to the extent those Effects adversely affect Navigant and its subsidiaries to a materially greater extent than they affect other entities in the corporate travel management industry;

8.4 Counterparts. This Agreement may be executed in counterparts, which together shall constitute one and the same agreement. The parties hereto may execute more than one copy of this Agreement, each of which shall constitute an original.

8.5 Entire Agreement. This Agreement (including the documents and the instruments referred to in this Agreement) and the Confidentiality Agreement constitute the entire agreement among the parties hereto and thereto and supersede all prior agreements and understandings, agreements or representations by or among the parties hereto and thereto, written and oral, with respect to the subject matter hereof and thereof.

8.6 Third-Party Beneficiaries. Except for the agreements set forth in Section 5.2(a), nothing in this Agreement, express or implied, is intended or shall be construed to create any third-party beneficiaries. Notwithstanding the foregoing, for purposes of Section 6.2(g) only, Accor shall be a third party beneficiary of this Agreement and no waiver of the condition set forth in Section 6.2(g) shall be effective unless such waiver is in writing executed by each of CWT and Accor.

8.7 Governing Law. This Agreement shall be governed and construed in accordance with the laws of the State of Delaware applicable to contracts executed in and to be performed in that State. All Actions arising out of or relating to this Agreement and the Confidentiality Agreement shall be heard and determined in any state or federal court sitting in the State of Delaware.

8.8 Consent to Jurisdiction; Venue.

(a) Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the state courts of Delaware and to the jurisdiction of the United States District Court for the District of Delaware for the purpose of any Action arising out of or relating to this Agreement and the Confidentiality Agreement, and each of the parties hereto irrevocably agrees that all claims in respect to such Action may be heard and determined exclusively in any Delaware state or federal court sitting in the State of Delaware. Each of the parties hereto agrees that a final judgment in any Action shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(b) Each of the parties hereto irrevocably consents to the service of any summons and complaint and any other process in any other Action relating to the Merger, on behalf of itself or its property, by the personal delivery of copies of such process to such party. Nothing in this Section 8.8 shall affect the right of any party hereto to serve legal process in any other manner permitted by law.

8.9 Specific Performance. The transactions contemplated by this Agreement are unique. Accordingly, each of the parties hereto acknowledges and agrees that, in addition to all other remedies to which it may be entitled, each of the parties hereto is entitled to a decree of specific performance; provided, that such party hereto was not in material default hereunder at the time of the other party’s material breach of the Agreement. The parties hereto agree that if CWT, Merger Sub or Navigant shall have failed to perform its obligations under this Agreement, then the party hereto seeking to enforce this Agreement against such nonperforming party under this Agreement shall be entitled to specific performance and injunctive and other equitable relief, and the parties hereto further agree to waive any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other equitable relief. This provision is without prejudice to any other rights that any party hereto may have against another party hereto for any failure to perform its obligations under this Agreement.

8.10 Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties hereto. Notwithstanding the foregoing, CWT may without such consent assign or delegate its rights and

obligations hereunder or under any instrument executed or delivered in connection herewith as collateral security to any lender or any other debt financing source providing financing in connection herewith, which assignment shall not relieve the assigning party of its obligations hereunder. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of and be enforceable by the parties hereto and their respective successors and assigns.

8.11 Amendment. This Agreement may be amended by the parties hereto at any time before or after approval of the Merger by the Navigant Stockholders; provided, however, that after any such approval, no amendment shall be made that by law requires further approval by the Navigant Stockholders without such approval having been obtained. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

8.12 Extension; Waiver. At any time prior to the Effective Time, the parties may (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto or (c) subject to the proviso of Section 8.11, waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights and the single or partial exercise of any rights hereof shall not preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

8.13 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable.

IN WITNESS WHEREOF, CWT, Merger Sub and Navigant have signed this Agreement as of the date first written above.
