              RE:   LEAP WIRELESS INTERNATIONAL, INC.
                    REGISTRATION STATEMENT ON FORM S-1 (FILE NO.333-101381)
                    NOTICE OF WITHDRAWAL

Dear Ladies and Gentlemen:

      The undersigned registrant hereby requests withdrawal of the
above-referenced Registration Statement, together with all exhibits thereto (the
"Registration Statement"). The Registration Statement was originally filed with
the Securities and Exchange Commission on November 21, 2002. The Registration
Statement has not been declared effective.

      On April 13, 2003, the registrant and substantially all of its
subsidiaries filed voluntary petitions for relief under Chapter 11 of the United
States Bankruptcy Code in the United States Bankruptcy Court for the Southern
District of California (jointly administered as Case Nos. 03-03470-LA to
03-03535-LA). In connection with its bankruptcy proceedings, registrant has
filed a schedule of executory contracts to be rejected which included
registrant's agreement containing registration rights provisions relating to
shares of common stock issued to MCG PCS, Inc., the selling security holder
under the Registration Statement. Rejection of the agreement is subject to
confirmation of the registrant's plan of reorganization by the Bankruptcy Court.
As a result, the registrant does not intend to cause the Registration Statement
to become effective and hereby makes application for withdrawal of the
Registration Statement on such grounds.

      If you have any questions regarding this application for withdrawal,
please contact Barry M. Clarkson of Latham & Watkins LLP at (858) 523-5406.

                                    Sincerely,

                                    Leap Wireless International, Inc.


                                    /s/ S. Douglas Hutcheson
