Dispute Resolution.

(a)

Escalation Events. All controversies, disputes, differences or claims between the parties arising out of or relating to this Agreement, including but not limited to any question relating to the existence, validity, termination, interpretation, performance or enforcement of this Agreement, will be deemed an “Escalation Event” and subject to the following escalation process. An Escalation Event first will be discussed in good faith by the parties at a mutually convenient location in an attempt to resolve the Escalation Event amicably, in whole or in part. A senior director or vice president of business development with decision- making authority of each party (“Senior Business People”) will participate in these discussions. If the Senior Business People cannot resolve the Escalation Event within five days, then each party will designate a senior executive with decision-making authority (“Senior Executive”) to meet and confer in an effort to resolve the Escalation Event. If the Senior Executives cannot resolve the Escalation Event within 5 days, then the chief executive officers of the respective parties (“CEO”) will meet and confer in an effort to resolve the Escalation Event. Any decisions and resolutions of the Senior Business People, Senior Executives or CEOs will be final and binding on the parties once reduced to writing and signed by the parties. If the procedures outlined under this Section 13.12(a) fail to resolve an Escalation Event, then the parties hereby agree to submit the issue to binding arbitration pursuant to Section 13.12(b).

(b)

Disputes, Arbitration. All Escalation Events that are not resolved according to Section 13.12(a) above (each, a “Dispute”) will be finally and exclusively settled by binding arbitration in accordance with the following:

(i)

Submission: Rules. Either party will be entitled to submit a Dispute to the American Arbitration Association (“AAA”) for binding arbitration in New York, New York by providing written notice

*	CONFIDENTIAL TREATMENT REQUESTED. OMITTED PORTIONS FILED WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

to the other party and to AAA. Discovery will be conducted in accordance with Rules 26 through 36 and Rule 45 of the Federal Rules of Civil Procedure.

(ii)

Appointment of Panel. The parties will assemble a panel of three arbitrators (the “Panel”) as follows: Each party will nominate one arbitrator, and those two arbitrators will select a chairperson of the Panel. Each arbitrator on the Panel must have at least five years senior management or consulting experience in the on-line services industry and must not have been employed by or a supplier to either party during the preceding two years.

(iii)

Timing. The parties will undertake commercially reasonable efforts to conclude any arbitral proceedings within 60 calendar days from the date on which the last arbitrator accepts his or her appointment; provided, however, that if the arbitral award is not issued within such 60 calendar days, then the arbitration proceedings will continue until an award is made.

(iv)

Legal and Equitable Remedies. Neither party will be entitled to file a legal action against the other party until the arbitration is concluded, but nothing herein prohibits a party from requesting temporary injunctive relief from any court of competent jurisdiction. Either party may at any time apply to a court of competent jurisdiction for equitable relief.

(v)

Decision. Any decision or award of the Panel will be based solely on the terms of this Agreement and the facts and legal arguments presented at the hearing and any documents presented in accordance with the discovery rules. The Panel will issue a written decision that sets forth its rationale in reasonable detail. Any award rendered by the Panel may be enforced by any court of competent jurisdiction. The Panel will have the authority to award specific performance or an injunction to the prevailing party, or to make an award of direct damages, but will have no right to grant special, punitive or exemplary damages, or indirect or consequential damages unless such amounts are allowed under this Agreement.

13.13

This Promotion Agreement has been executed by the parties effective as of the Effective Date.

The other party to the License granted by Orbitz is referred to as the “Licensee”. To the extent they may differ with the general terms below, the specific terms of the License govern all use of the Brand Features by the Licensee.

2. Materials using Orbitz Brand Features. Any and all materials using the Orbitz Brand Features to be developed by Licensee (whether itself or in consultation with Orbitz) will not be publicly disseminated without Orbitz’s prior written approval, which will not be unreasonably withheld or delayed. All trademarks and service marks included in the Orbitz Brand Features will be designated with “SM”, “TM” or “®”, in the manner directed by Orbitz. The Orbitz Brand Features will not be presented or used: a) in a manner that suggests that editorial content has been authored by, or represents the views or opinions of, any Orbitz personnel or Affiliate; b) in a manner that is misleading, defamatory, libelous, obscene, infringing or otherwise objectionable; c) in connection with any material that infringes the trademark, copyright or any other rights of any third party; d) as part of a name of a product or service of a company other than Orbitz; or e) in a manner that infringes, derogates, dilutes, or impairs the rights of Orbitz in the Orbitz Brand Features. Licensee will comply with the commercially reasonable standards established by Orbitz and communicated to Licensee with respect to the form of the Orbitz Brand Features and their usage.

3. Deficient use of Orbitz Brand Features. If Orbitz at any time finds any materials using Orbitz Brand Features to be deficient in quality or finds any materials being marketed in a misleading or deceptive manner, then Orbitz may notify Licensee of such deficiency, and Licensee will eliminate such deficiency within a commercially reasonable time.

4. Modifications of Trademark Usage Guidelines. Orbitz will have the right modify these guidelines, from time to time, with respect to the Orbitz Brand Features, upon prior written notice to Licensee.

5. Modification or Discontinuation of Orbitz Brand Features. In the event that Orbitz decides, in its sole discretion, to modify or discontinue the use of any Orbitz Brand Features, Licensee agrees, upon 120 days’ prior written notice from Orbitz, to refrain from using the unmodified or discontinued Orbitz Brand Features, destroy all designs, stationary, promotional materials, advertising or other materials of every kind using any of the unmodified or discontinued Orbitz Brand Features, and to commence using the modified or substituted Orbitz Brand Features within 120 days following Orbitz’s written notice.

Exhibit B

Detailed Requirements for Tracking System

Tracking System Objectives: The purpose of the tracking system (“System”) is to allow for Bookings generated from Clicks to be tracked using 30-Day Look Back Tracking and otherwise in accordance with the terms of this Agreement.

Data Collection:

Summary: The System will function by using URL parameters to identify sources and by using cookies to identify visitors coming from those sources.

URL parameters: For Orbitz to attribute Bookings to Clicks, the System must be able to identify the source of the lead as Kayak or otherwise. Unique tracking parameters in the URL of leads to Orbitz from a Kayak Site will designate Kayak as the source. The System must provide tracking parameters to Kayak and Kayak will include these in the linking URLs for all Kayak leads to Orbitz.

Cookies: The System must set cookies on end-users’ browsers to identify unique visitor sessions. These cookies will be used to associate returning visitors, look-back conversions (within 30 days), and repeat conversions to their original visitor sessions. The cookie will allow the system to identify the source from which these visitors originated based on the unique URL tracking parameters. It will be set each time a lead to an Orbitz Site is made. If the cookie has already been set for a prior lead, subsequent leads will override the previously set cookie and designate a new source, even if the new source may be the same as the previous source. For end-users that disable cookies in their browsers or delete cookies prior to a conversion, the system will not be able to look-back and associate conversions to prior leads. In this scenario, the conversion will only be attributed to the lead which creates a Booking in the same session. However, Orbitz will not provide Kayak with information regarding the type of conversion (unique session or latent conversion).

Data Presentation:

Data Aggregation: The System aggregates all user conversion data collected through the scripting and processes it.

Data Elements: At a minimum, the System will allow both Orbitz and Kayak to view reports which detail each conversion, date/time-stamp of conversion, corresponding transaction ID, associated revenue, attributed source (Kayak), date/time-stamp of most recent introduction from attributed source and attributed lead query (an O/D pair, destination, vacation package, queried keywords. matched keywords, etc.). For any given time frame, the reports will display revenue and conversion counts in an aggregate view and a daily view.
