                                LICENSE PURCHASE

               THIS LICENSE PURCHASE AGREEMENT (the "Agreement") is made the
11th day of September, 1998 by and between Leap Wireless International, Inc., a
Delaware Corporation (the "Buyer") and Airgate Wireless, L.L.C., a Delaware
limited Liability company (the "Seller").

               WHEREAS, Seller (i) has acquired the authorization of the Federal
Communications Commission (the "FCC") to construct and operate personal
communication systems ("PCS") in the Basic Trading Areas ("BTAs") listed on
Exhibit A attached hereto (collectively referred to herein as the "Licenses");

               WHEREAS, Seller desires to sell to Buyer and Buyer desires to
purchase from Seller all right, title and interest in and to the Licenses; and

               WHEREAS, Seller and Buyer desire to enter into this Agreement to
effect the purchase and sale of the Licenses pursuant to the terms set forth
herein except as specifically provided otherwise herein;

               WHEREAS, the prior consent of the FCC to the transfer of the
Licenses from the Seller to Buyer is required, and the parties intend that the
transactions contemplated by this Agreement will be consummated only if such
consent is obtained;

               NOW, THEREFORE, in consideration of the mutual covenants
contained herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto, each intending
to be legally bound, do hereby agree as follows:

1.      SALE AND PURCHASE OF LICENSES.

               (a) Purchase of Licenses. Subject to the terms and conditions set
forth herein, the Seller agrees to sell the Licenses to the Buyer and the Buyer
agrees to purchase the Licenses from the Seller at the Closing (as defined
below).

               (b) Purchase Price. Subject to adjustment as provided in
subparagraph (c) below, the purchase price for the Licenses shall be Nineteen
Million Four Hundred Fifty Thousand Dollars ($19,450,000) (the "Purchase
Price"), payable as set forth below:

                      (1) Upon execution of this Agreement, Buyer shall pay Six
Hundred Thousand Dollars ($600,000) (the "Initial Payment") to an escrow account
(the "Escrow") with Lukas Nace Gutierrez and Sachs, Chartered ("Escrow Agent"),
payable pursuant to an escrow agreement in form and substance as set forth in
Exhibit B. In the event this Agreement terminates pursuant to Section 2(a)
hereof, and the Closing does not occur for a reason attributable to a breach by
Buyer of its obligations under this Agreement, the Initial Payment shall be paid
to Seller upon the termination of this Agreement. Such payment shall constitute
liquidated damages, and Seller shall be entitled to the full amount of the
Initial Payment without having to demonstrate quantifiable damages, it being
recognized that accurate calculation of actual damages would prove

            to be impractical.

                      (2) Delivery of a cash payment in the amount equal to the
difference between the Purchase Price and the sum of (i) the outstanding
principal and accrued interest on the Assumed FCC debt at the time of closing
and (ii) the Initial Payment.

                      (3) Assumed Liabilities. On the Closing Date, the Buyer
shall assume and agrees to discharge the liabilities and obligations of Seller,
accruing after the Closing Date, under the FCC notes (individually the "FCC
Notes") and security agreements, copies of which Seller shall provide to Buyer
within three (3) business days (the "Assumed FCC Debt"). Subject to the
provisions of subparagraph (c) below, Seller agrees to make all payments due
under the Assumed FCC Debt up to and including the Closing Date. Other than the
Assumed FCC Debt, Buyer shall not assume or be obligated to pay, perform or
otherwise discharge any liability or obligation of the Seller, direct or
indirect, known or unknown, absolute or contingent.

               (c)    Adjustment to Purchase Price.

                      (1)    If the FCC has not granted the FCC Consent (as
                             defined below) within six (6) months after the
                             execution of this Agreement (the "Adjustment Date")
                             due to concerns about the Buyer's qualifications to
                             be a "Designated Entity" as provided in Section
                             3(e) below and the parties have timely entered into
                             the Management Agreement (as defined below), then
                             the Purchase Price shall be increased by an amount
                             equal to the interest payments Seller has made on
                             the Assumed FCC Debt from the Adjustment Date to
                             the Closing.

                      (2)    If the FCC shall impose any unjust enrichment
                             penalty upon Seller solely by virtue of Buyer not
                             qualifying for the same level Designated Entity
                             benefits for which Seller qualified, the Purchase
                             Price shall be increased by the amount of the
                             penalty imposed upon Seller.

               (d) Allocation of Purchase Price. The Purchase Price shall be
allocated such that 10% (Ten percent) ($1,945,000) of the Purchase Price shall
be allocated to the non-capitalization provision set forth in Section 5(f) of
this Agreement; provided that Buyer shall agree to any reasonable sub-allocation
of such Purchase Price, as may exist on a market by market, and may be
determined by Seller. Buyer and Seller will follow and use such allocation in
all income, sales and other tax returns, filings or other related reports made
by them to any governmental agencies. To the extent that disclosures of this
allocation are required to be made by the parties to the Internal Revenue
Service ("IRS") under the provisions of Section 1060 of the Internal Revenue
Code of 1986, as amended (the "Code") or any regulations thereunder, each of
Buyer and Seller will disclose such reports to the other prior to filing with
the IRS.

2.      CLOSING.

               (a) Closing Date. The Closing shall take place within ten (10)
days after the grant

been reversed, stayed, enjoined, set aside, annulled or suspended and (ii) With
