               AMENDMENT NO. 1 TO THE AMENDED AND RESTATED SYSTEM
                  EQUIPMENT PURCHASE AGREEMENT BETWEEN LUCENT
               TECHNOLOGIES INC. AND CRICKET COMMUNICATIONS, INC.

This Amendment No. 1 is entered into by and between Lucent Technologies Inc.
("LUCENT") and CRICKET Communications, Inc. ("CRICKET") as of this 22nd day of
March, 2002 ("Effective Date").

WHEREAS, the Parties have entered into that certain Amended and Restated System
Equipment Purchase Agreement dated June 30, 2000, as amended, under which
CRICKET may purchase products and services from LUCENT (hereafter "The Supply
Agreement"); and

WHEREAS, pursuant to The Supply Agreement, LUCENT has agreed to finance certain
products and services purchased by CRICKET thereunder; and

WHEREAS, the Parties have agreed to modify certain provisions of the Supply
Agreement as indicated herein;

NOW THEREFORE, in consideration of the mutual promises and covenants contained
herein, the Parties agree to amend The Supply Agreement as follows (terms not
otherwise defined herein shall have the meanings set forth in The Supply
Agreement):

1.      The heading of Section 24.7 of the Supply Agreement is hereby changed to
        the following:

        "24.7 Vendor's Right to Terminate and Pursue Remedies"

2.      Section 24.7(b) is hereby modified to read as follows:

        "(b) the Owner fails to make payments of undisputed amounts due to the
        Vendor pursuant to the terms of this Contract, which are more than
        thirty (30) days overdue, provided that such failure has continued for
        at least thirty (30) days after the Vendor has notified the Owner in
        writing of its right and intent to terminate on account of such overdue
        amount."

3.      A new Section 24.7(d) shall be added to the Supply Agreement and shall
        read as follows:

        "(d) (i) the Owner or any of Owner's subsidiaries is in material default
        of any Indebtedness (as such term is defined in the Amended and Restated
        Credit Agreement, dated as of September 20, 1999, as amended and
        restated as of October 20, 2000, among Cricket, Lucent and the other
        parties thereto, as amended to date) for borrowed money, that has an
        outstanding principal balance of at least Twenty-Five Million Dollars
        (US$25,000,000.00) in the aggregate

<PAGE>

        ("Indebtedness Default"), (ii) Owner or any of its subsidiaries has been
        served with notice of such Indebtedness Default under the terms of such
        Indebtedness, to the extent notice is required thereunder; and (iii)
        such Indebtedness Default has not been cured, waived or discharged in
        full, (including, through payment of the related Indebtedness) within
        the Cure Periods (as defined below) after Owner (or its subsidiaries as
        applicable) has been served with written notice of default. The "Cure
        Periods" for purposes of this paragraph shall be: 1) for an Indebtedness
        Default that is not a payment default, the cure period shall be as set
        forth in the agreement governing the applicable Indebtedness, and if
        said Indebtedness provides for no such cure period, then thirty (30)
        days; and 2) for payment Indebtedness Default, three (3) business days
        ("Cure Periods").

        Notwithstanding the provisions of the preceding paragraph of this
        subsection (d), Vendor's rights to terminate or pursue other claims
        pursuant to this subsection (d) as a result of a specific Indebtedness
        Default will be suspended in the event Owner has a bona fide dispute
        over the existence of such Indebtedness Default, provided a) Owner is
        diligently pursuing a resolution of the dispute in good faith; and b)
        Owner commences, within ninety (90) days after the end of the applicable
        Cure Period, formal mediation, arbitration, litigation or such other
        dispute resolution mechanism available to Owner under the subject
        Indebtedness.

        Within five (5) days after Owner's receipt of written notice of any
        Indebtedness Default, Owner shall notify Vendor of the Indebtedness
        Default in writing. Such notification will include the description of
        the default and a statement of Owner's intent to dispute such
        Indebtedness Default, if Owner has made such a determination at such
        time, and if Owner has not made such determination, then when Owner
        makes the determination, Owner will give notice thereof to Vendor."

4.      A new paragraph shall be added to the end of Section 24.7, after Section
        24.7(d), and shall read as follows:

        "In addition to the right to terminate this Contract as provided above,
        in the event any one or more of the events described in subsections
        24.7(a) through (d) above occurs, then Vendor, at its sole option, may
        exercise all legal rights and remedies it has available to it by law or
        equity, and specifically, the rights to stop any outstanding shipments,
        to cease performance until the default is cured (except for performance
        obligations arising under Sections 2.8, 12, 13, 14, 15, 16.3, 18, 19,
        20, 23, 24 and 26), to place a credit hold on Owner's purchases, to
        require revised payment terms for continued sales and purchases (except
        that no such revisions will be made to the provisions of Section 5.3(e)
        relative to late payment charges) for any outstanding payments due and
        to cancel any outstanding orders.

<PAGE>

5.      Section 24.8(a) is hereby modified to read as follows:

        "(a) In the event that funds sufficient to finance Owner's obligations
        under this Contract are not available to Owner under the Vendor
        Financing as a result of limitations imposed by Vendor by the definition
        of Available Commitment in the Vendor Financing, and provided that the
        unavailability of funds is not due to the expiration of the Vendor
        Financing, then i) each party's obligations to perform shall be
        suspended except for those obligations contained in Sections 2.8, 12.
        13, 14, 15, 16.3, 18, 19, 20, 23, 24 and 26, or as otherwise required by
        law, and (ii) if the cap remains in place for more than thirty (30)
        days, Owner shall be released from any obligations to purchase Equipment
        and Services under this Contract."

6.      In the event of a conflict between this Amendment and the Supply
        Agreement, this Amendment shall govern.

7.      All other terms and conditions contained in The Supply Agreement remain
        unchanged and in full force and effect and continue to apply to this
        Amendment.

AGREED:

Site: (i) the Services that have been completed, (ii) the Services that are
incomplete but will be finished by Vendor, and (iii) the management Services
that Vendor proposes to transition to Owner.

Vendor shall be released of all contractual obligations associated with the
tasks transitioned and assumed by Owner in writing.

Due to the above transition impacting Vendor's ability to control the triggers
for Services invoicing and billing per Section 5.3 of the Contract, the parties
agree that such Services for transitioned Sites will be billed as the Work is
performed and payment will be made within 30 days of such billing.

Vendor agrees that the actual Work performed per the E Exhibits, (except for the
management portion of such Services assumed by Owner after transition) will
continue to be financed in the same manner under the Contract and the Credit
Agreement. The parties will agree on the total dollar amount of financing
required after transition of such Services, which shall not exceed the amount of
financing already provided for under the Credit Agreement based on Vendor
providing the Services per the E Exhibits prior to any modification in Services
resulting from the transition. If the parties cannot agree on the amount of
financing required as a result of the transition of Services, then such
transition of Services, except as qualified above, will remain as currently
stated in the Contract.

19. Full Force and Effect. Except as expressly modified in this Amendment No. 2,
the Contract shall remain unmodified and in full force and effect.

20. Entirety of Amendment. This Amendment No. 2 to the Contract together with
the Contract, and related Credit Agreement, constitute the entirety of the
agreement between the parties with respect to the subject matter thereof, and no
modifications, alterations or waivers of any provision contained therein shall
be binding on the parties hereto unless evidenced in writing signed by duly
authorized representatives of both parties as set forth in the Contract. This
Amendment No. 2 shall specifically supercede, replace and is intended to
memorialize the contractual elements of the Letter Agreements that are still
applicable as of the Effective Date of this Amendment.

21. Execution. This Amendment No. 2 may be executed in one or more counterparts,
each of which shall be deemed to be an original hereof, but together shall
constitute but one and the same instrument. This Amendment No. 2 may be executed
by facsimile and the parties agree that such facsimile signatures shall have the
same force and effect as original signatures.
