                      THE LEAP WIRELESS INTERNATIONAL, INC.

                      EXECUTIVE OFFICER DEFERRED STOCK PLAN

        Leap Wireless International, Inc., a Delaware corporation (the
"Company"), by resolution of its Board of Directors, adopted The Leap Wireless
International, Inc. Executive Officer Deferred Stock Plan (the "Plan"),
effective as of December 9, 1999, for the benefit of the executive officers of
the Company.

        The Plan is a nonqualified deferred compensation plan pursuant to which
twenty-five percent (25%) of an executive officer's Bonus (as defined herein)
will be deferred and converted into Share Units (as defined herein) credited to
the officer's account under the Plan. Share Units will represent the right to
receive shares of the Company's Common Stock, par value $0.0001 per share
("Common Stock"), in accordance with the Plan. The Plan also provides that an
executive officer may elect to defer all or any portion of the remainder of such
executive officer's Bonus and that amounts the deferred at the election of an
executive officer will be converted into Share Units credited to the officer's
account under the Plan. Finally, the Plan provides for additional Share Units
that will be credited to the executive officer's account under the Plan,
determined based on the executive officer's Bonus deferrals pursuant to the
Plan. The Plan provides that the Share Units credited to an executive officer's
account will be distributed to such executive officer upon the earlier of the
date or dates designated by the officer or the officer's retirement, death,
Disability (as defined herein) or other termination of employment.

        The Plan is unfunded and is maintained primarily for the purpose of
providing deferred compensation for a select group of management or highly
compensated employees, within the meaning of Sections 201(2), 301(a)(3) and
401(a)(1) of the Employee Retirement Income Security Act of 1974, as amended.

        The Company may establish a grantor trust pursuant to the Plan and may
make contributions to the trust to provide for distributions of benefits to be
made under the Plan. The Company's contributions may be in the form of cash,
shares of Common Stock or other securities or property.

                      (iv) To provide that the obligations of the Company with
        respect to such Participant's Accounts be assumed by the successor or
        survivor corporation, or a parent or subsidiary thereof, or the rights
        of such Participant with respect to such Participant's Accounts shall be
        substituted for by similar rights covering units or amounts representing
        the stock of the successor or survivor corporation, or a parent or
        subsidiary thereof, with appropriate adjustments as to the number and
        kind of Share Units or other units or amounts credited to such
        Participant; and

                      (v) To make adjustments in the number and type of shares
        of Common Stock (or other securities or property) or cash amounts to be
        distributed to Participants and Beneficiaries under the Plan.

               (c) The existence of the Plan and the Accounts of Participants
under the Plan shall not affect or restrict in any way the right or power of the
Company or the shareholders of the Company to make or authorize any adjustment,
recapitalization, reorganization or other change in the Company's capital
structure or its business, any merger or consolidation of the Company, any issue
of stock or of options, warrants or rights to purchase stock or of bonds,
debentures, preferred or prior preference stocks whose rights are superior to or
affect the Common Stock or the rights thereof or which are convertible into or
exchangeable for Common Stock, or the dissolution or liquidation of the company,
or any sale or transfer of all or any part of its assets or business, or any
other corporate act or proceeding, whether of a similar character or otherwise.

Section 11.3  - Limitation on Rights of Employees

        The Plan is strictly a voluntary undertaking on the part of the Company
and shall not constitute a contract between a Company and any Employee with
respect to, or consideration for, or an inducement or condition of, the
employment of an Employee. Nothing contained in the Plan shall give any Employee
the right to be retained in the service of a Company or to interfere with or
restrict the rights of the Company, which are hereby expressly reserved, to
discharge or retire any Employee, except as provided by law, at any time without
notice and with or without cause. Inclusion under the Plan will not give any
Employee any right or claim to any benefit hereunder except to the extent such
right has specifically become fixed under the terms of the Plan. The doctrine of
substantial performance shall have no application to Employees, Participants,
"Beneficiaries" or any other persons entitled to payments under the Plan. Each
condition and provision, including numerical items, has been carefully
considered and constitutes the minimum limit on performance which will give rise
to the applicable right.

Section 11.4  - Unfunded Obligations of the Company

        The obligations of the Company under the Plan shall be unfunded and
unsecured, and nothing contained herein shall be construed as providing for
assets to be held in trust or escrow or any other form of segregation of the
assets of the Company for the benefit of any Participant, any Beneficiary or any
other person or persons to whom benefits are to be paid pursuant to the terms of
the Plan. The interest of any Participant, any Beneficiary or any other person
hereunder shall be limited to the right to receive the benefits as set forth
herein. To the extent



                                       15
<PAGE>   20

that a Participant, any Beneficiary or any other person acquires a right to
receive benefits under the Plan, such rights shall be no greater than the right
of an unsecured general creditor of the Companies.

Section 11.5 - Grantor Trust

               (a) The Company may establish a grantor trust (the "Trust") in
connection with the Plan, and may make irrevocable contributions to the Trust in
accordance with the terms of the trust agreement (the "Trust Agreement")
establishing the Trust. The Company shall designate the trustee of the Trust.
The Trust Agreement shall provide that the Trust assets shall be subject to the
claims of the creditors of the Company in the event of the "Insolvency" (as
defined in the Trust Agreement) of the Company, and that the Trust shall
constitute an unfunded arrangement and shall not affect the status of the Plan
as an unfunded plan for purposes of the Code and ERISA.

               (b) The Trust Agreement may provide that the trustee of the Trust
shall invest the assets in the Trust as directed by the Company. The Company
may, but shall not be obligated to, direct the trustee to invest the assets of
the Trust in shares of Common Stock.

               (c) The Company may cause the payment of benefits under the Plan
to be made, in whole or in part, by the Trust in accordance with the terms of
the Trust Agreement.

               (d) Any payment of benefits by the Trust shall be in satisfaction
of the obligations of the Company under the Plan. Notwithstanding the
establishment of the Trust, and any contributions made by the Company to the
Trust, the Company shall remain obligated to make all payments of benefits under
the Plan, except to the extent such payments are made by the Trust in accordance
with the Trust Agreement.

               (e) To the extent the Company establishes the Trust and directs
that the assets of the Trust be invested in shares of Common Stock, all voting
rights on shares of Company Stock in the Trust Fund held by the Trust shall be
exercised by the Trustee in accordance with instructions from the Participants
with respect to the Share Units credited to their Accounts, or the Administrator
in accordance with the following provisions of this Section:

                      (i) All voting rights on shares of Company Stock in the
        Trust shall be exercised by the Trustee only as directed by the
        Participants with respect to shares of Company Stock attributable to the
        Share Units credited to their Accounts in accordance with the following
        provisions of subsections (ii) and (iii) below.

                      (ii) As soon as practicable before each annual or special
        shareholders' meeting of the Company at which shares of Company Stock
        are entitled to vote, the Trustee shall furnish to each Participant a
        copy of the proxy solicitation material sent generally to stockholders,
        together with a form requesting confidential instructions on how the
        shares of Company Stock attributable to the Share Units credited to such
        Participant's Accounts (including fractional shares to 1/1000th of a
        share) are to be voted. The Company shall cooperate with the Trustee to
        ensure that Participants receive the requisite information in a timely
        manner. The materials furnished to the Participants shall include a
        notice from the Trustee explaining each Participant's right to instruct
        the Trustee with respect to the voting of the shares of Company Stock
        attributable to the Share Units credited to the Participant's Accounts.
        Upon timely receipt of such instructions, the Trustee (after combining
        votes of fractional shares to give effect to the greatest extent to
        Participants' instructions) shall vote the shares as instructed. If
        voting instructions for shares of Company Stock to the Accounts of any
        Participant are not timely received by the Trustee for a particular
        stockholders' meeting, such shares shall not be voted in accordance with
        the instructions but shall be voted as provided in subsection (c) below.
        The instructions received by the Trustee from Participants shall be held
        by the Trustee in strict confidence and shall not be divulged or
        released to any person including directors, officers or employees of the
        Company, or of any other company, except as otherwise required by law.

<PAGE>   21

                      (iii) All shares of Company Stock attributable to Share
        Units credited to the Accounts of Participants shall be voted only in
        accordance with the directions of such Participants as given to the
        Trustee. Each Participant shall be entitled to 1/1000th of a share)
        attributable to Share Units credited to his Accounts. If, however,
        voting instructions for shares of Company Stock to the Participant's
        Accounts are not timely received by the Trustee for a particular
        stockholders' meeting, such shares shall be voted by the Trustee as
        directed by the Administrator.

Section 11.6  - Consolidation or Merger

               In the event of the consolidation or merger of a Company with or
into any other corporation, or the sale by a Company of its assets, the
resulting successor may continue the Plan by adopting it in a resolution of its
board of directors or agreement of its partners. If within 90 days from the
effective date of such consolidation, merger or sale of assets, such new
corporation does not adopt the Plan, the Plan shall be terminated.

Section 11.7  - Errors and Misstatements

        In the event of any misstatement or omission of fact by a Participant to
the Administrator or any clerical error resulting in payment of benefits in an
incorrect amount, the Administrator shall promptly cause the amount of future
payments to be corrected upon discovery of the facts and the Companies shall pay
the Participant or any other person entitled to payment under the Plan any
underpayment in cash in a lump sum or to recoup any overpayment from future
payments to the Participant or any other person entitled to payment under the
Plan in such amounts as the Administrator shall direct or to proceed against the
Participant or any other person entitled to payment under the Plan for recovery
of any such overpayment.

Section 11.8 - Payment on Behalf of Minor, etc.

        In the event any amount becomes payable under the Plan to a minor or a
person who, in the sole judgment of the Administrator is considered by reason of
physical or mental condition to be unable to give a valid receipt therefor, the
Administrator may direct that such payment be made to any person found by the
Administrator in its sole judgment, to have assumed the care of such minor or
other person. Any payment made pursuant to such determination shall constitute a
full release and discharge of the Companies, the Board, the Administrator, the
Committee and their officers, directors and Employees.

Section 11.9  - Amendment of Plan

        As limited by any applicable law, the Plan may be wholly or partially
amended by the Board from time to time including retroactive amendments
necessary to conform to the provisions and requirements of ERISA or the Code or
regulations pursuant thereto; provided, however, that no amendment shall
decrease the Vested percentage or amount of interest any Participant or any
other person entitled to payment under the Plan has in the Participant's
Nonqualified Accounts.

Section 11.10  - Tax Withholding

        The Company shall be entitled to require payment in cash or deduction
from other compensation payable to a Participant of any sums required by
federal, state or local tax law to be withheld with respect to the crediting of
Share Units to a Participant's Accounts and the distribution of amounts to such
Participant. The Administrator may in its discretion and in satisfaction of the
foregoing requirement allow such Holder to elect to have the Company withhold
shares of Common Stock otherwise distributable under the Plan (or allow the
return of shares of Common Stock) having a Fair Market Value equal to the sums
required to be withheld.

Section 11.11   - Governing Law

        This Plan shall be construed, administered and governed in all respects
under and by applicable federal laws and, where state law is applicable, the
laws of the State of California.
