WHEREAS, TRX desires to engage WT to provide certain services and WT desires to accept such engagement; and

WHEREAS, this Agreement amends and restates that certain Shared Services Agreement entered into by and between WT and WorldTravel Technologies, LLC, a wholly owned subsidiary of TRX, dated November 1,1999 (the “Original Agreement”).

NOW, THEREFORE, in consideration of the premises and of the promises and agreements hereinafter set forth, the parties hereto, intending to be legally bound, do hereby agree as follows:

1. The Services.

1.1 Services. WT agrees to provide various services as set forth on Exhibit A (the “Services”) to TRX under the terms and conditions provided herein. The individuals who provide the Services will be referred to as “WT Personnel.”

1.2 Additional Services. TRX may desire that WT perform additional services that are different from or in addition to, the Services, including, but not limited to, industry relations, marketing and business development (“Additional Services”). WT will provide such Additional Services as TRX may reasonably request, upon such terms and conditions (including compensation terms) as are mutually agreed to in writing between the parties, which written agreement shall be attached to this Agreement and incorporated herein by reference. Exhibit A shall be amended to reflect any such Additional Services. In no event shall WT be obligated to perform any Additional Services, including any Additional Services that would cause it to be in conflict with any law, rule or regulation, or any internal WT policy. TRX shall not resell the Services or Additional Services provided hereunder to any third party without the prior written consent of WT.

TRX shall be responsible for its proportionate amount (as determined in good faith by the parties) of any fees, costs or expenses WT incurs from any third party as a direct result of any change set forth in (i) or (ii) above. WT shall have no obligation to commence work in connection with any change of the type described in either clause (i) or (ii) above until the fee impact of such change is agreed upon by the parties in writing.

mutually acceptable adjustment, the matter shall be handled in accordance with the Section 9 (Dispute Resolution).

10.8 Severability. If any provision of this Agreement is found to be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

10.9 Waiver. No delay or omission by either party to exercise any right or power under this Agreement or pursuant to applicable law shall impair such right or power or be

8

construed as a waiver thereof. A waiver by any party of any covenant or breach shall not be construed to be a waiver of any other covenant or succeeding breach.
