SECTION 3. Disputes.

agreements, shall not prevent the enforcement of these covenants.

SECTION 4. Blue-Penciling.

If any court or arbitrator, as the case may be, determines that any restrictive covenant herein, or any part thereof, is unenforceable because of the duration or geographic scope of such provisions or other reason, it is the intention of the parties that such court shall have the power to modify any such provisions to the extent necessary to render the provisions enforceable, and such provisions as so modified shall be enforced.

SECTION 5. Amendments.

This Agreement may not be amended except by an instrument in writing signed by the parties hereto; provided, however, that this Agreement may not be amended unless Worldspan and Buyer offer to enter into the same amendment with Northwest and American with respect to each of the Northwest Non-Competition Agreement and the American Non-Competition Agreement, respectively.
