|1. | Current Software License Agreement - 2011 Agreement Year.  With respect to the final year (commencing January 1, 2011 and ending December 31, 2011, to be referred to as the “2011 Agreement Year”) of the Current Software License Agreement, Orbitz shall pay ITA fees as set forth in this Paragraph 1.  The terms set forth in this Paragraph 1 shall supersede any inconsistent provisions in the Current Software License Agreement.

|a. | License Fee.  The license fee for Orbitz' use of QPX will be $(***) (“2011 Agreement Year License Fee”), based on a per-PNR charge of $(***)/PNR for the first (***) QPX-Powered PNRs.  For the QPX-Powered PNRs in excess of (***), Orbitz shall pay ITA $(***)/PNR.  ITA shall credit the excess amounts from Orbitz' payment of $(***) (made March 31, 2010) toward the payment of excess PNRs created during the 2011 Agreement Year or any excess fees due from Orbitz to ITA for the 2011 Agreement Year.  Promptly following the end of the 2011 Agreement Year, if the excess amount has not been fully applied, ITA will refund the remainder to Orbitz.

|-- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|b. | Excess Query Fee.  If Orbitz's look-to-book ratio exceeds (***) Queries:1 QPX-Powered PNR, Orbitz shall pay an excess query fee (which will not be counted toward the 2011 Agreement Year Annual License Fee) of $(***)/Query.  The look-to-book ratio of (***) Queries:1 QPX-Powered PNR shall be calculated on a blended basis across the Orbitz Sites, the Third Party Sites and the White Label Sites.  For the avoidance of doubt, split Queries, with no regard to whether ITA or Orbitz generates, will count as one Query.

|5. | ITA Technology; Updates; New Technology.  “QPX”, as provided to Orbitz under the New Agreement and in the 2011 Agreement Year, will include all modifications, enhancements, improvements, updates and upgrades to the current functionality which are generally made available by ITA to ITA customers (all of the foregoing, collectively, “QPX Enhancements”), including any future releases or versions of such products and services and any successor or replacement products or services that provide similar functionality as the current functionality or which provide functionality that is used as a replacement for the current functionality.  “QPX Enhancements” will not include “New Products”, which are defined as products and services provided by ITA to its customers that are related to QPX but have substantially different functionality to the then-existing ITA Technology, and that are not used as a replacement for any functionality within the ITA Technology.  Although Fast QPX may fall within the definition of “QPX Enhancements” above, because Fast QPX requires significantly increased processing power and/or expenditures on hardware as compared to the current QPX, the Parties expressly agree that Fast QPX will be deemed a New Product unless alternative functionality is no longer available in QPX because it is retired or replaced by Fast QPX, in which case Fast QPX will be provided as part of QPX.




ITA shall make available to Orbitz QPX Enhancements and New Products on the same time frame and on terms no less favorable than they are made available to other ITA customers.

|a. | License Fee.  ITA proposes a (***)%(***) in the license fee (relative to that set forth in the Current Software License Agreement) associated with Orbitz' use of ITA Technology with respect to the minimum number of PNRs, and a (***)%(***) in the license fee for PNRs in excess of the minimum.  This (***) would be applied to the per-PNR fee and would affect the Annual Minimum.  The license fee for Orbitz's use of the ITA Technology will be based on a per-PNR charge of $(***)/PNR for the first (***) ITA Technology-powered PNRs created during any Agreement Year, and $(***) per PNR for PNRs in excess of (***).  Orbitz shall pay ITA an annual license fee (“Annual License Fee”) of $(***), representing (***) ITA Technology-powered PNRs per year.  Orbitz shall pay the Annual License Fee on March 31 of the year prior to the commencement of the New Agreement Year, as per the Current Agreement.

|b. | Excess Query Fee.  If Orbitz's look-to-book ratio exceeds (***) queries:1 ITA Technology-powered PNR, Orbitz shall pay an excess query fee (which will not be counted toward the Annual License Fee) of $(***)/query.  The look-to-book ratio of (***) queries:1 ITA Technology-powered PNR shall be calculated on a blended basis across the Orbitz Sites, the Third Party Sites and the White Label Sites.  For the avoidance of doubt, split queries, with no regard to whether ITA or Orbitz generates, will count as one query.
