                               FIRST AMENDMENT TO
                 WHOLESALE SOLUTIONS SWITCHED SERVICES AGREEMENT

Confidential Treatment. The portions of this exhibit that have been replaced
with "[*****]" have been filed separately with the Securities and Exchange
Commission and are the subject of an application for confidential treatment.

This First Amendment (WSG0307-028r2) is made to the Wholesale Solutions Switched
Services Agreement (WSG0206-048r18s) between SPRINT COMMUNICATIONS COMPANY L.P.
("Sprint") and VALOR TELECOMMUNICATIONS ENTERPRISES, LLC ("Customer") signed by
Customer on July 2, 2003 and by Sprint on or about July 3, 2003 (collectively,
the "Agreement"). The following modified and added terms and conditions are made
a part of the Agreement effective the first day of the first billing month after
this First Amendment is signed by Sprint and Customer ("First Amendment
Effective Date") if Customer signs and returns this Agreement to Sprint by the
8th day of the current billing month. Otherwise, the First Amendment Effective
Date is the first day of the second billing month after the month that Sprint
signs the First Amendment.

Sprint and Customer agree as follows:

1.       The Agreement is amended by deleting Attachment D-1 in its entirety and
         replacing it with the Attachment D-1 attached to this Amendment and
         incorporated by reference.

2.       To become effective, the First Amendment must be signed by an
         authorized representative of Customer. Any change to this First
         Amendment is subject to written acceptance by a Sprint officer. All
         other terms and conditions in the Agreement, not amended above, will
         remain in effect. This First Amendment and any information concerning
         its terms and conditions are Sprint's proprietary information and are
         governed by the parties' Nondisclosure Agreement.

3.       Sprint's offer to amend the Agreement will be withdrawn if this First
         Amendment is not executed by both parties within 45 days after
         September 30, 2003.
