<PAGE>

the Plan and this Agreement, for a period of thirty (30) days commencing
following the earliest to occur of the following events (each, a "DISTRIBUTION
EVENT"):

                           (i) the date Holder has a Termination of Employment,
         Termination of Consultancy or Termination of Directorship, as
         applicable;

                           (ii) the date immediately prior to a Change in
         Control; or

                           (iii) August 15, 2005.

                  (b) Following a Distribution Event, Holder may purchase the
shares of Common Stock issuable with respect to his or her vested Deferred Stock
Units by delivery to the Secretary of the Company or the Secretary's office of
all of the following within thirty (30) days following the occurrence of the
Distribution Event.

                           (i) A Purchase Notice in writing signed by the Holder
         or any other person then entitled to purchase the shares of Common
         Stock issuable with respect to the vested Deferred Stock Units, stating
         that such shares of Common Stock are being purchased, such notice
         complying with all applicable rules established by the Administrator.
         Such notice shall be substantially in the form attached as Exhibit B to
         the Grant Notice (or such other form as is prescribed by the
         Administrator); and

                           (ii) Full payment (in cash or by check) for the
         shares of Common Stock to be purchased by Holder, including payment of
         any applicable withholding tax, which in the discretion of the
         Administrator may be in any form permitted by Section 10.4 of the Plan;
         and

                           (iii) A bona fide written representation and
         agreement, in such form as is prescribed by the Administrator, signed
         by Holder or the other person then entitled to purchase the shares of
         Common Stock issuable with respect to the vested Deferred Stock Units,
         stating that the shares of Common Stock are being acquired for Holder's
         own account, for investment and without any present intention of
         distributing or reselling said shares or any of them except as may be
         permitted under the Securities Act and then applicable rules and
         regulations thereunder, and that Holder or the other person then
         entitled to purchase the shares of Common Stock issuable with respect
         to the vested Deferred Stock Units will indemnify the Company against
         and hold it free and harmless from any loss, damage, expense or
         liability resulting to the Company if any sale or distribution of the
         shares by such person is contrary to the representation and agreement
         referred to above. The Administrator may, in its absolute discretion,
         take whatever additional actions it deems appropriate to ensure the
         observance and performance of such representation and agreement and to
         effect compliance with the Securities Act and any other federal or
         state securities laws or regulations. Without limiting the generality
         of the foregoing, the Administrator may require an opinion of counsel
         acceptable to it to the effect that any subsequent transfer of shares
         acquired by Holder does not violate the Securities Act, and may issue
         stop-transfer orders covering such shares. Share certificates
         evidencing Common Stock issued pursuant to the Deferred Stock Units
         shall bear an appropriate legend referring to the provisions of this
         subsection (c) and the agreements

<PAGE>

         herein. The written representation and agreement referred to in the
         first sentence of this subsection (c) shall, however, not be required
         if the shares to be issued pursuant to such exercise have been
         registered under the Securities Act, and such registration is then
         effective in respect of such shares; and

                           (iv) In the event the shares of Common Stock issuable
         with respect to the vested Deferred Stock Units shall be purchased
         pursuant to this Section 2.4(b) by any person or persons other than
         Holder, appropriate proof of the right of such person or persons to
         purchase such shares of Common Stock.

                  (c) Subject to the conditions of Sections 2.4(b) and 2.6, the
Company shall distribute any shares of Common Stock purchased pursuant to this
Section 2.4(b) in a single lump sum distribution. If Holder does not purchase
the shares of Common Stock issuable with respect to any vested Deferred Stock
Units within thirty (30) days following the occurrence of a Distribution Event,
such Deferred Stock Units shall terminate.

                  (d) All distributions shall be made by the Company in the form
of whole shares of Common Stock (and cash in an amount equal to the value of any
fractional Deferred Stock Unit, determined based on the Fair Market Value as of
the distribution date).

                  (e) Neither the time nor form of distribution of the Deferred
Stock Units under this Agreement may be changed, except as may be provided by
the Plan.

                  (f) Notwithstanding the foregoing, shares of Common Stock
shall be issuable pursuant to a Deferred Stock Unit at such times and upon such
events as are specified in this Agreement only to the extent issuance under such
terms will not cause the Deferred Stock Units or the shares of Common Stock
issuable pursuant to the Deferred Stock Units to be includible in the gross
income of Holder under Section 409A of the Code prior to such times or the
occurrence of such events, as permitted by the Code and the regulations and
other guidance thereunder.

         2.5 Restrictions on Transfer. Unless otherwise permitted by the
Administrator pursuant to the Plan, no Deferred Stock Units or shares of Common
Stock issuable with respect thereto or any interest or right therein or part
thereof shall be liable for the debts, contracts or engagements of Holder or his
or her successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect.

         2.6 Conditions to Issuance of Stock Certificates. The shares of Common
Stock deliverable with respect to the Deferred Stock Units, or any portion
thereof, may be either previously authorized but unissued shares or issued
shares which have then been reacquired by the Company. Such shares shall be
fully paid and nonassessable. The Company shall not be required to issue or
deliver any shares of Common Stock with respect to the Deferred Stock Units
prior to fulfillment of all of the following conditions:

                  (a) The admission of such shares to listing on all stock
exchanges on which such Common Stock is then listed; and

<PAGE>

                  (b) The completion of any registration or other qualification
of such shares under any state or federal law or under rulings or regulations of
the Securities and Exchange Commission or of any other governmental regulatory
body, which the Administrator shall, in its absolute discretion, deem necessary
or advisable; and

                  (c) The obtaining of any approval or other clearance from any
state or federal governmental agency which the Administrator shall, in its
absolute discretion, determine to be necessary or advisable; and

                  (d) The lapse of such reasonable period of time following the
applicable Distribution Event as the Administrator may from time to time
establish for reasons of administrative convenience; and

                  (e) The receipt by the Company of full payment for such
shares, including payment of all amounts which, under federal, state or local
tax law, the Company (or other employer corporation) is required to withhold
upon issuance of such shares in accordance with Section 10.4 of the Plan.

         2.7 Rights as Stockholder. Except as otherwise provided herein, Holder
shall not be, nor have any of the rights or privileges of, a stockholder of the
Company in respect of any shares issuable pursuant to the Deferred Stock Units
unless and until such shares shall have been issued by the Company to Holder.

any sums required by federal, state or local tax law to be withheld with respect
to the issuance or distribution of the Deferred Stock Units or shares of Common
Stock issuable with respect thereto. The Company shall not be obligated to
deliver any new certificate representing shares of Common Stock issuable with
respect to the Deferred Stock Units to Holder or his legal representative unless
and until Holder or his legal representative shall have paid or otherwise
satisfied in full the amount of all federal,

<PAGE>

state and local taxes applicable to the taxable income of Holder resulting from
the grant of the Deferred Stock Units or the distribution of the shares of
Common Stock issuable with respect thereto.

         3.3 Limitations Applicable to Section 16 Persons. Notwithstanding any
other provision of the Plan or this Agreement, if Holder is subject to Section
16 of the Exchange Act, the Plan, the Deferred Stock Units and the shares of
Common stock issuable with respect thereto and this Agreement shall be subject
to any additional limitations set forth in any applicable exemptive rule under
Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of the

interpretation and application of the Plan as are consistent therewith and to
interpret, amend or revoke any such rules. All actions taken and all
interpretations and determinations made by the Administrator in good faith shall
be final and binding upon Holder, the Company and all other interested persons.
No member of the Administrator shall be personally liable for any action,
determination or interpretation made in good faith with respect to the Plan,
this Agreement or the Deferred Stock Units. In its absolute discretion, the
Board may at any time and from time to time exercise any and all rights and
duties of the Administrator under the Plan and this Agreement.

Stock issued hereunder shall be endorsed with any legend required by any
applicable federal and state securities laws.

                  (b) Holder agrees that, in order to ensure compliance with the
restrictions referred to herein, the Company may issue appropriate "stop
transfer" instructions to its transfer agent, if any, and that, if the Company
transfers its own securities, it may make appropriate notations to the same
effect in its own records.

                  (c) The Company shall not be required: (i) to transfer on its
books any shares of Common Stock that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement, or (ii) to treat as owner
of such shares of Common Stock or to accord the right to vote or pay dividends
to any purchaser or other transferee to whom such shares shall have been so
transferred.

to the Company shall be addressed to the Company in care of the Secretary of the
Company, and any notice to be given to Holder shall be addressed to Holder at

given pursuant to this Section 3.6, either party may hereafter designate a
different address for notices to be given to that party. Any notice shall be
deemed duly given when sent via email or when sent by certified mail (return
receipt requested)
<PAGE>

and deposited (with postage prepaid) in a post office or branch post office
regularly maintained by the United States Postal Service.

         3.7 Titles. Titles are provided herein for convenience only and are not
to serve as a basis for interpretation or construction of this Agreement.

         3.8 Governing Law; Severability. This Agreement shall be administered,
interpreted and enforced under the laws of the State of Delaware without regard
to conflicts of laws thereof. Should any provision of this Agreement be
determined by a court of law to be illegal or unenforceable, the other
provisions shall nevertheless remain effective and shall remain enforceable.

         3.9 Conformity to Securities Laws. Holder acknowledges that the Plan is
intended to conform to the extent necessary with all provisions of the
Securities Act and the Exchange Act and any and all regulations and rules
promulgated by the Securities and Exchange Commission thereunder, and state
securities laws and regulations. Notwithstanding anything herein to the
contrary, the Plan shall be administered, and the Deferred Stock Units are
granted, only in such a manner as to conform to such laws, rules and
regulations. To the extent permitted by applicable law, the Plan and this
Agreement shall be deemed amended to the extent necessary to conform to such
laws, rules and regulations.

         3.10 Amendments. This Agreement may not be modified, amended or
terminated except by an instrument in writing, signed by Holder and by a duly
authorized representative of the Company.

         3.11 No Employment Rights. If Holder is an Employee, nothing in the
Plan or this Agreement shall confer upon Holder any right to continue in the
employ of the Company or any Subsidiary or shall interfere with or restrict in
any way the rights of the Company and its Subsidiaries, which are expressly
reserved, to discharge Holder at any time for any reason whatsoever, with or
without cause, except to the extent expressly provided otherwise in a written
agreement between the Company and Holder.

         3.12 Successors and Assigns. The Company may assign any of its rights
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Holder and his or her heirs, executors, administrators, successors and
assigns.

         3.13 Unfunded, Unsecured Obligations. The obligations of the Company
under the Plan and this Agreement 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 Holder or any other person. Holder shall have only the rights of a
general, unsecured creditor of the Company with respect to the Deferred Stock
Units, unless and until shares of Common Stock shall be distributed to Holder
under the terms and conditions of this Agreement.

and procedures from time to time established by the Board of Directors of the
Parent. EXECUTIVE's duties to the Parent shall be those customarily assigned to
an executive holding similar positions in a comparable corporation engaged in a
business similar to the business of the Parent. In his role as an officer of
Parent, EXECUTIVE shall report directly to the Parent's Chief Executive Officer,
and shall devote such of his time as is appropriate (in light of his position
with the Company) to the activities of the Parent working from the Parent's
headquarters in San Diego, California, or other business locations, subject to
Parent-related business travel. Executive shall not receive any compensation or
benefits for such services other than the compensation and benefits provided for
in this Agreement.

2.    Loyal and Conscientious Performance.

      2.1   During his employment with the Company, EXECUTIVE shall faithfully
and diligently devote EXECUTIVE's full business time and efforts to the
performance of the duties of his executive management position with the Company
(except as otherwise provided in Paragraph 1.3 above and Paragraph 2.2 below),
and, following his appointment or election, the duties of the President and
Chief Financial Officer of the Company, with the degree of loyalty and care
prescribed by law, provided that EXECUTIVE shall be permitted to continue to
serve on the boards of directors/trustees/advisors of Scientific Materials, Inc.
and San Diego Children's Museum, and no other boards of directors or similar
obligations, unless approved by the Company's Chief Executive Officer, so long
as his services do not materially and adversely affect EXECUTIVE's ability to
perform his duties hereunder as reasonably determined by the Company's Board of
Directors. This Employment Agreement is a personal services contract whereby the
Company and Parent are engaging the services of EXECUTIVE.

      2.2   The Company and the Parent agree that EXECUTIVE may devote up to
three business days per month pursuing outside business interests provided such
business interests do not compete with the Company's or the Parent's business.

3.    Term of Employment.

      3.1   EXECUTIVE shall be employed pursuant to the terms of this Agreement
for a term beginning on the Effective Date and expiring at midnight on February
28, 2006. The term of employment, including any extension period contemplated in
Paragraph 3.2 below, shall be referred to as the "Employment Period."

      3.2   This Agreement and EXECUTIVE's employment hereunder may be extended
for such period following February 28, 2006, and upon such terms and conditions,
as shall be mutually agreed upon by the Company, the Parent and EXECUTIVE and
set forth in a written amendment to this Agreement.

      3.3   Notwithstanding Paragraphs 3.1 and 3.2, EXECUTIVE's employment may
terminate in accordance with Paragraph 5 and, in the event of such termination,
the Employment Period shall end on the Date of Termination (as defined in
Paragraph 5.8 below).

4.    Compensation and Benefits.

      4.1   Beginning with the Effective Date, and during the Employment Period,
Company shall pay EXECUTIVE a salary (the "Base Salary") of three hundred thirty
five thousand dollars ($335,000) per year, payable bi-weekly in accordance with
the Company's normal payroll practices for EXECUTIVE, such salary subject to
adjustment from time to time pursuant to periodic reviews by the Company's Board
of Directors (with input, if any, from the Compensation Committee of the Board
of Directors of Parent).

      4.2   The Company shall pay EXECUTIVE a success bonus in the amount of
three hundred thousand dollars ($300,000) as follows:

                  (a)   Not later than fourteen (14) days after the Effective
      Date, the Company shall pay EXECUTIVE a lump sum payment in cash in the
      amount of one hundred fifty thousand dollars ($150,000), and

                  (b)   Not later than January 31, 2005, the Company shall pay
      EXECUTIVE an additional lump sum payment in cash in the amount of one
      hundred fifty thousand dollars ($150,000).

      4.3   During the Employment Period, EXECUTIVE's annual target performance
bonus ("Target Performance Bonus") shall be sixty-five percent (65%) of
EXECUTIVE's Base Salary, and EXECUTIVE shall be eligible to be paid an annual
performance bonus with respect to each calendar year (including 2004), with the
amount of such bonus to be paid to EXECUTIVE determined in accordance with the
Company's prevailing annual performance bonus practices that are used to
determine annual performance bonuses for the senior executives of the Company
generally; provided, however, that, in the event EXECUTIVE is employed by the
Company on the earlier of (i) the date on which the final installments of the
2005 annual performance bonuses for senior executives are paid by the Company,
and (ii) February 28, 2006, then EXECUTIVE shall be paid any final installment
of his 2005 annual performance bonus, calculated as set forth above, on the date
on which the final installments of the 2005 annual performance bonuses for
senior executives are paid, without regard to whether EXECUTIVE is then employed
by the Company.

      4.4   The EXECUTIVE shall be entitled to the following benefits during the
Employment Period:

                                      - 3
<PAGE>

            4.4.1 All benefits to which other executive officers of the Company
are entitled as determined by the Company's Board of Directors, on terms no less
favorable than other such participants, including but not limited to,
participation in any and all retirement plans, bonus and incentive payment
programs (provided that such participation would not duplicate Executive's bonus
entitlement pursuant to Paragraph 4.3), group life insurance policies and plans,
medical, health, dental and disability insurance policies and plans, and the
like, which may be maintained by the Company for the benefit of its executive
officers.

            4.4.2 Four (4) weeks of Scheduled Time Off ("STO") per year under
the Company's Paid Time Off ("PTO") policy, which shall accrue and may be used
by EXECUTIVE in accordance with the Company's then prevailing PTO practices.

in a manner consistent with the Company's policies and practices for senior
executives.

      4.5   The Company shall reimburse EXECUTIVE for all reasonable
out-of-pocket expenses incurred by him in the course of performing his duties
under this Agreement (whether such reimbursement is sought before or after
termination of this Agreement), to the extent consistent with the Company's
policies in effect from time to time with respect to travel, entertainment and
other business expenses, subject to the Company's requirements with respect to
reporting and documentation of such expenses pursuant to Company policy.

      4.6   All of EXECUTIVE's compensation shall be subject to applicable
federal and state withholding taxes and any other employment taxes as are
required to be collected or withheld by the Company.

      4.7   The Parent has adopted the Leap Wireless International, Inc. 2004
Stock Option, Restricted Stock and Deferred Stock Unit Plan (the "Parent Plan").
Not later than sixty (60) days after the Effective Date, the Parent shall grant,
or cause to be granted, to EXECUTIVE the awards described in Exhibit A hereto
(the "Awards") under the Plan. The terms and conditions of the Awards shall be
set forth in the Restricted Stock Award Grant Notice and Restricted Stock Award
Agreement (attached as Attachment A-1 hereto), the Stock Option Grant Notice and
Non-Qualified Stock Option Agreement (attached as Attachment A-2 hereto) and the
Deferred Stock Unit Award Grant Notice and Deferred Stock Unit Award Agreement
(attached as Attachment A-3 hereto), respectively, and shall be subject to the
terms and conditions of the Plan (as in effect from time to time).

      4.8   If, during the Employment Period, all or substantially all of the
assets of the Company of shares of stock of the Company or Parent having fifty
percent (50%) or more of the voting rights of the total outstanding stock of the
Company or Parent, as the case may be, are sold with the approval of or pursuant
to the active solicitation of the Board of Directors of the Company or the Board
of Directors of the Parent, whichever is applicable, to a strategic investor
(i.e. an investor whose primary business is not financial investing ) the
Company shall pay to EXECUTIVE a stay bonus in a lump sum payment in cash in an
amount equal to EXECUTIVE's Base Salary (at the annual rate then in effect) for
a period of eighteen (18) months, if the EXECUTIVE continues his Employment with
the Company ( or its successor) for a two (2)

                                      - 4
<PAGE>

month period commencing on the date of the closing of such sale. Such lump sum
cash payment shall be made within fifteen (15) days following the expiration of
the two (2) month period.

5.       Termination of Employment.

      5.1   EXECUTIVE's employment under this Agreement shall terminate without
notice upon the date of EXECUTIVE's death. In the event of EXECUTIVE's death,
all rights of EXECUTIVE to compensation hereunder shall automatically terminate
immediately upon his death, except that EXECUTIVE's heirs, personal
representatives or estate shall be entitled to any unpaid portion of his salary
and accrued benefits earned up to the date of his death, including a pro rata
share of EXECUTIVE's Target Performance Bonus for the year of his death.

      5.2   The Company may terminate EXECUTIVE's employment under this
Agreement after thirty (30) days notice in the event that EXECUTIVE is unable to
substantially perform his duties for an aggregate period of sixty (60) days
during any 180-day period resulting from EXECUTIVE's incapacity due to a
physical or mental disability after attempts to reasonably accommodate
EXECUTIVE's disability have failed. In the event that, during the Employment
Period, EXECUTIVE's employment is terminated for disability, EXECUTIVE shall be
entitled to any unpaid portion of his salary and accrued benefits earned up to
the Date of Termination, including a pro rata share of EXECUTIVE's Target
Performance Bonus for the year in which his termination occurs.

      5.3   The Company may terminate EXECUTIVE's employment under this
Agreement for Cause (as defined in Paragraph 5.5 below). In the event that,
EXECUTIVE's employment is terminated by the Company for Cause during the
Employment Period, EXECUTIVE shall be entitled to any unpaid portion of his
salary and accrued benefits earned up to the Date of Termination.

      5.4   The Company may terminate EXECUTIVE's employment under this
Agreement other than for Cause, and EXECUTIVE may terminate his employment under
this Agreement for Good Reason (as defined in Paragraph 5.6 below). In the event
that, EXECUTIVE's employment is terminated by the Company other than for Cause,
or by EXECUTIVE for Good Reason, during the remaining Employment Period,
EXECUTIVE shall be entitled to the following:

            5.4.1 EXECUTIVE shall be entitled to any unpaid portion of his
salary and accrued benefits earned up to the Date of Termination.

            5.4.2 The Company shall pay EXECUTIVE (i) a severance benefit in the
form of a lump sum payment in cash in an amount equal to the EXECUTIVE's Base
Salary (at the annual rate then in effect) for a period of nine (9) months which
shall be made within thirty (30) days after the date of termination and (ii)
monthly payments for nine months commencing on the first day of the ninth month
following the date of termination equal to the EXECUTIVE's Base Salary;
provided, however, that the monthly severance benefit shall be reduced by the
amount, if any, that the EXECUTIVE receives from employment with a subsequent
employer or for services as an independent contractor during the period during
which the monthly payments are paid. Upon written request from the Company, made
not more than monthly during the period

                                      - 5
<PAGE>

during which such monthly payments are paid, EXECUTIVE shall furnish the Company
with a statement as to whether he is employed or acting as an independent
contractor and the amount of compensation (including salary, wages, bonuses and
fees for services) therefrom; if EXECUTIVE fails to furnish the statement within
thirty (30) days of the Company's request or furnishes a materially false
statement, the Company may, in its sole discretion, reduce or permanently
discontinue any further monthly payments under this Paragraph 5.4.2.
Notwithstanding the foregoing, no payments shall be made to EXECUTIVE under this
Paragraph 5.4.2 in the event that EXECUTIVE has been paid or is entitled to a
payment under Paragraph 4.8.

            5.4.3 In the event that the Date of Termination occurs on or prior
to December 31, 2005, the Company shall pay EXECUTIVE an additional lump sum
payment in cash in an amount equal to the excess (if any) of: (i) EXECUTIVE's
Target Performance Bonus for 2005, over (ii) any portion of EXECUTIVE's annual
performance bonus for 2005 already paid to EXECUTIVE. Such lump sum cash payment
shall be made within thirty (30) days after the Date of Termination and shall be
in lieu of any annual performance bonus with respect to 2005, or any remaining
installments thereof, otherwise payable under Paragraph 4.3.

            5.4.4 To the extent EXECUTIVE elects continuation health care
coverage for EXECUTIVE and his eligible dependents under Section 4980B of the
Internal Revenue Code of 1986, as amended from time to time (the "Code"), and
Sections 601-608 of the Employee Retirement Income Security Act of 1974, as
amended from time to time (collectively, "COBRA Coverage"), EXECUTIVE shall
not-be required to pay premiums for such COBRA Coverage for the eighteen (18)
month period commencing on the Date of Termination (or, if earlier, until
EXECUTIVE is eligible for comparable coverage with a subsequent employer).

            5.4.5 EXECUTIVE shall not be required to mitigate the amount of any
payment provided for in this Paragraph 5.4 by seeking other employment or
otherwise nor, except as provided in Paragraphs 5.4.2 and 5.4.4, shall the
amount of any payment or benefit provided for in this Paragraph 5.4 be reduced
by any compensation or benefits earned by EXECUTIVE as the result of employment
by another employer or self-employment, by retirement benefits, by offset
against any amount claimed to be owed by EXECUTIVE to the Company, or otherwise.

      5.5   For purposes of this Paragraph 5, "Cause" shall mean termination of
EXECUTIVE's employment by the Company: (i) upon EXECUTIVE's willful failure
substantially to perform EXECUTIVE's duties with the Company (or the Parent)
(other than any such failure resulting from EXECUTIVE's incapacity due to
physical or mental illness or any such actual or anticipated failure after
EXECUTIVE's issuance of a Notice of Termination (as defined below) for Good
Reason), as reasonably determined by the Company, after a written demand for
substantial performance is delivered to EXECUTIVE by the Board of Directors of
the Company, which demand specifically identifies the manner in which the Board
of Directors of the Company believes that EXECUTIVE has not substantially
performed such duties, provided that the EXECUTIVE shall have been given a
reasonable period, not to exceed fifteen (15) days, in which to cure such
failure (provided such failure is capable of being cured), (ii) upon EXECUTIVE's
willful failure substantially to follow and comply with the specific and lawful
directives of the Board of Directors of the Company (or the Board of Directors
of the

                                      - 6
<PAGE>

Parent) which are consistent with EXECUTIVE's duties with the Company (or the
Parent), as reasonably determined by the Board of Directors of the Company
(other than any such failure resulting from EXECUTIVE's incapacity due to
physical or mental illness or any such actual or anticipated failure after
EXECUTIVE's issuance of a Notice of Termination for Good Reason), after a
written demand for substantial performance is delivered to EXECUTIVE by the
Board of Directors of the Company, which demand specifically identifies the
manner in which the Board of Directors of the Company believes that EXECUTIVE
has not substantially performed such directives, provided that the EXECUTIVE
shall have been given a reasonable period not to exceed fifteen (15) days in
which to cure such failure (provided such failure is capable of being cured),
(iii) upon EXECUTIVE's commission of an act of fraud or dishonesty materially
impacting or involving the Company (or the Parent), or (iv) upon EXECUTIVE's
willful engagement in illegal conduct or gross misconduct. Notwithstanding the
foregoing, EXECUTIVE's employment shall not be deemed terminated for "Cause"
pursuant to this Paragraph 5.5 unless and until there shall have been delivered
to EXECUTIVE a copy of a resolution duly adopted by the affirmative vote of not
less than a majority of the entire membership of the Board of Directors of the
Company at a meeting of the Board of Directors of the Company held within three
(3) days (or such longer time period as the Board of Directors of the Company
may determine) after the Company provides the EXECUTIVE with notice that it has
determined that an event described in clauses (i) through (iv) of this Paragraph
5.5 has occurred, at which the EXECUTIVE, together with EXECUTIVE's counsel may
be heard for a period of no more than three (3) hours before the Company. The
determination of whether the EXECUTIVE's employment shall be terminated for
"Cause" shall be made by the Board of Directors of the Company in its sole
discretion.

      5.6   For purposes of this Paragraph 5, "Good Reason" shall mean, without
EXECUTIVE's express written consent, the occurrence of any of the following
circumstances unless such circumstances are cured (provided such circumstances
are capable of being cured) prior to the Date of Termination specified in the
Notice of Termination given in respect thereof: (i) the continuous assignment to
EXECUTIVE of any duties materially inconsistent with EXECUTIVE's positions with
the Company (or the Parent), a significant adverse alteration in the nature or
status of EXECUTIVE's responsibilities or the conditions of EXECUTIVE's
employment with the Company (or the Parent), or any other action that results in
a material diminution in EXECUTIVE's position, authority, title, duties or
responsibilities with the Company (or the Parent); (ii) reduction of EXECUTIVE's
annual Base Salary as in effect on the Effective Date or as the same may be
increased from time to time thereafter; (iii) the relocation of the Company's
offices at which EXECUTIVE is principally employed to a location more than sixty
(60) miles from such location, but only after the EXECUTIVE has commuted for a
period of one year to the new location (with the Company bearing the reasonable
cost of such commuting); (iv) the Company's failure to pay EXECUTIVE any portion
of EXECUTIVE's current compensation; (v) the Company's failure to continue in
effect any material compensation or benefit plan in which EXECUTIVE
participates, unless an equitable arrangement (embodied in an ongoing substitute
or alternative plan) has been made with respect to such plan, or the Company's
failure to continue EXECUTIVE's participation therein (or in such substitute or
alternative plan) on the basis not materially less favorable, both in terms of
the amount of benefits provided and the level of EXECUTIVE's participation
relative to other participants; (vi) the Company's failure to continue to
provide EXECUTIVE with benefits substantially similar in

                                      - 7
<PAGE>

the aggregate to those enjoyed by EXECUTIVE under any of the Company's life
insurance, medical, health and accident, disability, pension, retirement, or
other benefit plans in which EXECUTIVE or EXECUTIVE's eligible family members
were participating immediately prior thereto, or the taking of any action by the
Company which would directly or indirectly materially reduce any of such
benefits; or (vii) the continuation or repetition, after written notice of
objection from EXECUTIVE, of harassing or denigrating treatment of EXECUTIVE by
the Company inconsistent with EXECUTIVE's position with the Company or (viii) if
a successor to Company does not retain EXECUTIVE'S services for at least one
year on substantially the same terms as Sections 4.1 and 4.2 of this Agreement
which includes the obligation to assume the Company's obligations under this
Agreement. EXECUTIVE's right to terminate employment with the Company pursuant
to Paragraph 5.4 shall not be affected by EXECUTIVE's incapacity due to physical
or mental illness. EXECUTIVE's continued employment with the Company shall not
constitute consent to, or a waiver of rights with respect to, any circumstance
constituting Good Reason thereunder. The appointment or election of EXECUTIVE as
President and Chief Financial Officer of the Company (or the Parent) and the
assignment to EXECUTIVE of the duties, responsibilities and authority such
positions shall not constitute "Good Reason."

      5.7   Any purported termination of EXECUTIVE's employment by the Company
for Cause or other than for Cause, or by EXECUTIVE for Good Reason, shall be
communicated by Notice of Termination to the other party hereto in accordance
with Paragraph 10. "Notice of Termination" shall mean a written notice that
shall indicate the specific termination provision in this Paragraph 5 relied
upon and shall set forth in reasonable detail any facts and circumstances
claimed to provide a basis for the termination of employment under the provision
so indicated.

      5.8   For purposes of this Paragraph 5, "Date of Termination" shall mean
the date specified in the Notice of Termination (which, in the case of a
termination by the Company for Cause may occur immediately upon giving the
Notice of Termination, and, in the case of a termination by the Company other
than for Cause, or by EXECUTIVE for Good Reason, shall not be less than fifteen
(15) nor more than sixty (60) days after the date such Notice of Termination is
given), or, if EXECUTIVE's employment terminates by reason of EXECUTIVE's death
or disability, the date of such termination.

      5.9   In consideration of, and as a condition to receiving, the benefits
to be provided to EXECUTIVE under this Paragraph 5 (other than any unpaid
portion of his salary and accrued benefits earned up to the Date of
Termination), EXECUTIVE (or, in the event of EXECUTIVE's death, the executor or
legal representative of his estate) shall execute and deliver to the Company and
to the Parent, the "General Release" set forth on Exhibit B hereto on or after
the Date of Termination and not later than twenty-one (21) days after the Date
of Termination (or, in the event that the termination of EXECUTIVE's employment
with the Company is in connection with an exit incentive or other employment
termination program offered to a group or class of employees, not later than
forty-five (45) days after the Date of Termination (or, if later, the date
EXECUTIVE is provided with the information required in accordance with Section
3(f) of the General Release)). In the event that EXECUTIVE fails to execute and
deliver the General Release in accordance with this Paragraph 5.9, or EXECUTIVE
revokes the General Release in accordance with the terms thereof, EXECUTIVE
shall not receive the benefits set forth in this

                                      - 8
<PAGE>

Paragraph 5 (other than any unpaid portion of his salary and accrued benefits
earned up to the Date of Termination).

      5.10  As further consideration for the benefits to be provided under this
Paragraph 5 (other than any unpaid portion of his salary and accrued benefits
earned up to the Date of Termination), EXECUTIVE hereby agrees as follows:

            5.10.1 For the period commencing on the Date of Termination and
terminating on the second anniversary thereof, EXECUTIVE shall not, either on
EXECUTIVE's own account or jointly with or as a manager, agent, officer,
employee, consultant, partner, joint venturer, owner or shareholder or otherwise
on behalf of any other person, firm or corporation, directly or indirectly
solicit or attempt to solicit away from the Company, the Parent, or any of their
respective affiliates, any of their respective officers or employees or offer
employment to any person who, on or during the six (6) months immediately
preceding the date of such solicitation or offer, is or was an officer or
employee of the Company, the Parent, or any of their respective affiliates;
provided, however, that a general advertisement to which an officer or employee
of the Company, the Parent, or any of their respective affiliates, responds and
any employment resulting from such response shall in no event be deemed to
result in a breach of this Paragraph 5.10.1.

            5.10.2 In the event that EXECUTIVE breaches the provisions of
Paragraph 5.10.1, or threatens to do so, in addition to and without limiting or
waiving any other remedies available to the Company or the Parent in law or in
equity, the Company or the Parent shall be entitled to immediate injunctive
relief in any court having the capacity to grant such relief, to restrain such
breach or threatened breach and to enforce Paragraph 5.10.1. EXECUTIVE
acknowledges that it is impossible to measure in money the damages that the
Company will sustain in the event that EXECUTIVE breaches or threatens to breach
Paragraph 5.10.1 and, in the event that the Company or the Parent institutes any
action or proceeding to enforce Paragraph 5.10.1 seeking injunctive relief,
EXECUTIVE hereby waives and agrees not to assert or use as a defense a claim or
defense that the Company or the Parent has an adequate remedy at law. Also, in
addition to any other remedies available to the Company or the Parent in law or
in equity, in the event that EXECUTIVE breaches the provisions of Paragraph
5.10.1 in any material respect, EXECUTIVE shall forfeit EXECUTIVE's right to
further benefits under Paragraph 5 and EXECUTIVE shall be obligated to repay to
the Company the benefits that EXECUTIVE has received under Paragraph 5.

      5.11  Notwithstanding the foregoing provision of this Paragraph 5, the
payments provided for in this Paragraph 5 (other than unpaid salary earned prior
to termination and the monthly severance payments pursuant paragraph 5.4.2)
shall be made not later than the tenth day following the date on which the
General Release by EXECUTIVE becomes irrevocable.

6.    Parachute Payment Excise Tax Gross-Up.

      6.1   In the event that the EXECUTIVE'S employment under this Agreement is
(i) terminated by the Company other than for Cause or (ii) by the EXECUTIVE for
Good Reason, in each case within one (1) year of a Change in Control (as defined
in the Parent Plan, as in effect on the Effective Date) and it is determined
under this Paragraph 6 that any payment or

                                      - 9
<PAGE>

benefit to EXECUTIVE or for EXECUTIVE's benefit or on EXECUTIVE's behalf
(whether paid or payable or distributed or distributable) pursuant to the terms
of this Agreement or any other agreement, arrangement or plan with the Company
or any Affiliate (as defined below) (individually, a "Payment" and collectively,
the "Payments") would be subject to the excise tax imposed by Section 4999 of
the Code (the "Excise Tax"), then EXECUTIVE shall be entitled to receive from
the Company one or more additional payments (individually, a "Gross-Up Payment"
and collectively, the "Gross-Up Payments"), such that the net amount of the
Payments and the Gross-Up Payments retained by EXECUTIVE after the payment of
all Excise Taxes (and any interest or penalties imposed with respect to such
Excise Taxes) on the Payments, and all federal, state and local income tax,
employment tax and Excise Taxes (including any interest or penalties imposed
with respect to such taxes) on the Gross-Up Payments provided for in this
Paragraph 6, shall be equal to the Payments. For purposes of this Paragraph 6,
an "Affiliate" shall mean Parent, any successor to all or substantially all of
the business and/or assets of the Company or the Parent, any person acquiring
ownership or effective control of the Company or the Parent or ownership of a
substantial portion of the assets of the Company or the Parent, or any person
whose relationship to the Company, the Parent or such person is such as to
require attribution under Section 318(a) of the Code.

            6.1.1 All determinations required to be made under this Paragraph 6,
including whether and when any Gross-Up Payment is required and the amount of
such Gross-Up Payment, and the assumptions to be utilized in arriving at such
determinations shall be made by the Accountants (as defined below) which shall
provide EXECUTIVE and the Company with detailed supporting calculations with
respect to such Gross-Up Payment within fifteen (15) business days of the
receipt of notice from EXECUTIVE or the Company that EXECUTIVE has received or
will receive a Payment. For the purposes of this Paragraph 6, the "Accountants"
shall mean the Company's independent certified public accountants serving
immediately prior to the "change in the ownership or effective control of a
corporation" or "change in the ownership of a substantial portion of the assets
of a corporation", as defined in Code Section 280G, with respect to which the
determination is being made. In the event that the Accountants are also serving
as the accountants or auditors for the individual, entity or group effecting the
"change in the ownership or effective control of a corporation" or "change in
the ownership of a substantial portion of the assets of a corporation", as
defined in Code Section 280G, with respect to which the determination is being
made, Company shall appoint another nationally recognized public accounting
firm, reasonably acceptable to the EXECUTIVE, to make the determinations
required hereunder (which accounting firm shall then be referred to as the
Accountants hereunder). All fees and expenses of the Accountants shall be borne
solely by the Company.

            6.1.2 For the purposes of determining whether any of the Payments
will be subject to the Excise Tax and the amount of such Excise Tax, such
Payments shall be treated as "parachute payments" within the meaning of Section
280G of the Code, and all "parachute payments" in excess of the "base amount"
(as defined under Section 280G(b)(3) of the Code) shall be treated as subject to
the Excise Tax, unless and except to the extent that, in the opinion of the
Accountants, such Payments (in whole or in part) either do not constitute
"parachute payments" or represent reasonable compensation for services actually
rendered (within the meaning of Section 280G(b)(4) of the Code) in excess of the
"base amount," or such "parachute payments" are otherwise not subject to such
Excise Tax.

                                      - 10
<PAGE>

            6.1.3 For purposes of determining the amount of the Gross-Up
Payment, EXECUTIVE shall be deemed to pay federal income taxes at the highest
applicable marginal rate of federal income taxation for the calendar year in
which the Gross-Up Payment is to be made and to pay any applicable state and
local income taxes at the highest applicable marginal rate of taxation for the
calendar year in which the Gross-Up Payment is to be made, net of the maximum
reduction in federal income taxes which could be obtained from the deduction of
such state or local taxes if paid in such year (determined without regard to
limitations on deductions based upon the amount of EXECUTIVE's adjusted gross
income); and to have otherwise allowable deductions for federal, state and local
income tax purposes at least equal to those disallowed because of the inclusion
of the Gross-Up Payment in EXECUTIVE's adjusted gross income. To the extent
practicable, any Gross-Up Payment with respect to any Payment shall be paid by
the Company at the time EXECUTIVE is entitled to receive the Payment and in no
event will any Gross-Up Payment be paid later than five days after the receipt
by EXECUTIVE of the Accountant's determination.

            6.1.4 Any determination by the Accountants shall be binding upon the
Company and EXECUTIVE. As a result of uncertainty in the application of Section
4999 of the Code at the time of the initial determination by the Accountants
hereunder, it is possible that the Gross-Up Payment made will have been an
amount less than the Company should have paid pursuant to this Paragraph 6 (the
"Underpayment"), or more than the Company should have paid pursuant to this
Paragraph 6 (the "Overpayment"). In the event that the Company exhausts its
remedies pursuant to Paragraph 6 and EXECUTIVE is required to make a payment of
any Excise Tax, the Underpayment shall be promptly paid by the Company to or for
EXECUTIVE's benefit (together with interest at the rate provided in Section
1274(b)(2)(B) of the Code. In the event it is determined that there has been an
Overpayment, the Overpayment shall be promptly paid by EXECUTIVE to the Company
(together with interest at the rate provided in Section 1274(b)(2)(B) of the
Code).

            6.1.5 EXECUTIVE shall notify the Company in writing of any claim by
the Internal Revenue Service that, if successful, would require the payment by
the Company of the Gross-Up Payment. Such notification shall be given as soon as
practicable after EXECUTIVE is informed in writing of such claim and shall
apprise the Company of the nature of such claim and the date on which such claim
is requested to be paid. EXECUTIVE shall not pay such claim prior to the
expiration of the 30-day period following the date on which EXECUTIVE gives such
notice to the Company (or such shorter period ending on the date that any
payment of taxes, interest and/or penalties with respect to such claim is due).
If the Company notifies EXECUTIVE in writing prior to the expiration of such
period that it desires to contest such claim, EXECUTIVE shall: (i) give the
Company any information reasonably requested by the Company relating to such
claim; (ii) take such action in connection with contesting such claim as the
Company shall reasonably request in writing from time to time, including,
without limitation, accepting legal representation with respect to such claim by
an attorney reasonably selected by the Company; (iii) cooperate with the Company
in good faith in order to effectively contest such claim; and (iv) permit the
Company to participate in any proceedings relating to such claims; provided,
however, that the Company shall bear and pay directly all costs and expenses
(including additional interest and penalties) incurred in connection with such
contest and shall indemnify EXECUTIVE for and hold EXECUTIVE harmless from, on
an after-tax basis, any

                                      - 11
<PAGE>

Excise Tax or income or other taxes (including interest and penalties with
respect thereto) imposed as a result of such representation and payment of all
related costs and expenses.

            6.1.6 Without limiting the foregoing provisions of this Paragraph 6,
the Company shall control all proceedings taken in connection with such contest
and, at its sole option, may pursue or forgo any and all administrative appeals,
proceedings, hearings and conferences with the taxing authority in respect of
such claim and may, at its sole option, either direct EXECUTIVE to pay the tax
claimed and sue for a refund or contest the claim in any permissible manner, and
EXECUTIVE agrees to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more
appellate courts, as the Company shall determine; provided, however, that if the
Company directs EXECUTIVE to pay such claim and sue for a refund, the Company
shall advance the amount of such payment to EXECUTIVE, on an interest-free
basis, and shall indemnify EXECUTIVE for and hold EXECUTIVE harmless from, on an
after-tax basis, any Excise Tax or income or other taxes (including interest or
penalties with respect thereto) imposed with respect to such advance or with
respect to any imputed income with respect to such advance (including as a
result of any forgiveness by the Company of such advance); provided, further,
that any extension of the statute of limitations relating to the payment of
taxes for the taxable year of EXECUTIVE with respect to which such contested
amount is claimed to be due is limited solely to such contested amount.
Furthermore, the Company's control of the contest shall be limited to issues
with respect to which a Gross-Up Payment would be payable hereunder and
EXECUTIVE shall be entitled to settle or contest, as the case may be, any other
issue raised by the Internal Revenue Service or any other taxing authority.

            6.1.7 Notwithstanding the foregoing provisions of this Paragraph
6.1, if the EXECUTIVE terminated his employment for Good Reason, he shall, upon
the written request of the Company and reasonable advance notice, provide
consulting services to the Company (or to the Parent at the direction of the
Company, or both) for up to three (3) days per month for up to a one (1) year
period following his Date of Termination. The EXECUTIVE shall be entitled to
payment by the Company in the amount of $1,500 for each day on which he provides
consulting services pursuant to such written request from the Company. The
Company and the EXECUTIVE shall mutually use their best efforts to schedule the
date or dates on which EXECUTIVE will provide the requested consulting services
so as not to prevent EXECUTIVE from being gainfully employed by a subsequent
employer, and shall be arranged so as to reasonably accommodate EXECUTIVE's
vacation or other personal affairs. Notwithstanding any other provision of this
Paragraph 6, if EXECUTIVE refuses or otherwise fails to perform the requested
consulting services, if any, he shall forfeit his right to the payment of any
Gross-Up Payments or indemnification hereunder, and if any such Gross-Up
Payments or indemnification had previously been paid by the Company to the
EXECUTIVE hereunder, EXECUTIVE shall promptly repay such amount or amounts to
the Company within five (5) business days following the Company's written demand
therefor.

            6.1.8 Notwithstanding the foregoing provisions of this Paragraph 6,
in no event shall the Company's liability for Gross-Up Payments as
indemnification under this Paragraph 6 exceed one million dollars ($1,000,000).

                                      - 12
<PAGE>

      6.2   In the event of the termination of EXECUTIVE's employment with the
Company, any Gross-Up Payment to be made to EXECUTIVE pursuant to this Section 6
shall be made not later than the tenth day following the date on which the
General Release by EXECUTIVE becomes irrevocable (or, if later, the tenth day
following the date the "change in the ownership or effective control of a
corporation" or "change in a substantial portion of the assets of a corporation"
occurs); provided, however, if the Gross-Up Payment cannot be finally determined
on or before such day, the Company shall pay to EXECUTIVE on such day an
estimate, as determined in good faith by the Company, of the minimum amount of
such GrossUp Payment and shall pay the remainder of such Gross-Up Payment
(together with interest at the rate provided in Section 1274(b)(2)(B) of the
Code) as soon as the amount thereof can be determined but in no event later than
the thirtieth day after the Date of Termination. In the event that the amount of
the estimated Gross-Up Payment exceeds the amount subsequently determined to
have been due, such excess shall constitute a loan by the Company to EXECUTIVE,
payable on the fifth day after demand by the Company (together with interest at
the rate provided in Section 1274(b)(2)(B) of the Code).

7.    Proprietary and Confidential Information.

      7.1   Prior to the execution of this Agreement, EXECUTIVE executed the
Company's standard form of Invention Disclosure, Confidentiality and Proprietary
Rights Agreement which, among other matters, requires EXECUTIVE to maintain the
confidentiality of certain Company information. Such Invention Disclosure,
Confidentiality and Proprietary Rights Agreement shall remain in full force and
effect in accordance with the terms and conditions thereof.

      7.2   EXECUTIVE will exercise reasonable care, consistent with good
business judgment to preserve in good working order, subject to reasonable wear
and tear from authorized usage, and to prevent loss of, any equipment,
instruments or accessories of the Company in his custody for the purpose of
conducting the business of the Company. Upon request, EXECUTIVE will promptly
surrender the same to the Company at the conclusion of his employment, or if not
surrendered, EXECUTIVE will account to the Company to its reasonable
satisfaction as to the present location of all such instruments or accessories
and the business purpose for their placement at such location. At the conclusion
of EXECUTIVE's employment with the Company, he agrees to return such instruments
or accessories to the Company or to account for same to the Company's reasonable
satisfaction.

8.    Termination of Severance Benefits Agreement.

      8.1   In consideration of the execution and delivery of this Agreement by
the Company and the Parent, the Severance Agreement, dated May 30, 2003, by and
among EXECUTIVE, the Parent and the Company (the "Severance Benefits Agreement")
is hereby terminated effective as of the Effective Date. From and after the
Effective Date, EXECUTIVE waives any and all rights, claims, benefits and awards
under the Severance Agreement and releases the Parent and the Company from any

restrictions herein, including the right to vote the Shares and to receive all
dividends or other distributions paid or made with respect to the Shares;
provided, however, that any and all cash dividends paid on such Shares and any
and all shares of Common Stock, capital stock or other securities received by or
distributed to Holder with respect to the Shares as a result of any stock
dividend stock split, reverse stock split, recapitalization, combination,
reclassification, or similar change in the capital structure of the Company

                             RESTRICTIONS ON SHARES

      3.1   Repurchase Option. Subject to the provisions of Section 3.2 below,
if Holder has a Termination of Employment, Termination of Directorship or
Termination of Consultancy, as applicable, before all of the Shares are released
from the Company's Repurchase Option (as defined below), the Company shall, upon
the date of such Termination (as reasonably fixed and determined by the
Company), have an irrevocable, exclusive option, but not the obligation, for a
period of sixty (60) days, commencing ninety (90) days after the date Holder has
a Termination of Employment, Termination of Directorship or Termination of
Consultancy, as applicable, to repurchase all or any portion of the Unreleased
Shares (as defined below in Section 3.3) at such time (the "Repurchase Option")
at the original cash purchase price per share (the "Repurchase Price"). The
Repurchase Option shall lapse and terminate one hundred fifty (150) days after

                                      -2-
<PAGE>

Holder has a Termination of Employment, Termination of Directorship or
Termination of Consultancy, as applicable. The Repurchase Option shall be
exercisable by the Company by written notice to Holder or Holder's executor
(with a copy to the escrow agent appointed pursuant to Section 4.1 below) and
shall be exercisable, at the Company's option, by delivery to Holder or Holder's
executor with such notice of a check in the amount of the Repurchase Price times
the number of Shares to be repurchased (the "Aggregate Repurchase Price"). Upon
delivery of such notice and the payment of the Aggregate Repurchase Price, the
Company shall become the legal and beneficial owner of the Shares being
repurchased and all rights and interests therein or relating thereto, and the
Company shall have the right to retain and transfer to its own name the number
of Shares being repurchased by the Company. In the event the Company repurchases
any Shares under this Section 3.1, any dividends or other distributions paid on
such Shares and held by the escrow agent pursuant to Section 4.1 and the Joint
Escrow Instructions shall be promptly paid by the escrow agent to the Company.

      3.2   Release of Shares from Repurchase Restriction. The Shares shall be
released from the Company's Repurchase Option as indicated in Exhibit B to the
Grant Notice. Any of the Shares released from the Company's Repurchase Option
shall thereupon be released from the restrictions on transfer under Section 3.4.
In the event any of the Shares are released from the Company's Repurchase
Option, any dividends or other distributions paid on such Shares and held by the
escrow agent pursuant to Section 4.1 and the Joint Escrow Instructions shall be
promptly paid by the escrow agent to the Holder.

      3.3   Unreleased Shares. Any of the Shares which, from time to time, have
not yet been released from the Company's Repurchase Option are referred to
herein as "Unreleased Shares."

      3.4   Restrictions on Transfer. Unless otherwise permitted by the
Administrator pursuant to the Plan, no Unreleased Shares or any dividends or
other distributions thereon or any interest or right therein or part thereof,
shall be liable for the debts, contracts or engagements of the Holder or his
successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect.

                                   ARTICLE IV

                                ESCROW OF SHARES

      4.1   Escrow of Shares. To insure the availability for delivery of
Holder's Unreleased Shares upon repurchase by the Company pursuant to the
Repurchase Option under Section 3.1, Holder hereby appoints the Secretary of the
Company, or any other person designated by the Administrator as escrow agent, as
his or her attorney-in-fact to assign and transfer unto the Company, such
Unreleased Shares, if any, repurchased by the Company pursuant to the Repurchase
Option pursuant to Section 3.1 and any dividends or other distributions thereon,
and shall, upon execution of this Agreement, deliver and deposit with the
Secretary of the Company, or such other person designated by the Administrator,
any share certificates representing the

                                      -3-
<PAGE>

Unreleased Shares, together with the stock assignment duly endorsed in blank,
attached to the Grant Notice as Exhibit D to the Grant Notice. The Unreleased
Shares and stock assignment shall be held by the Secretary of the Company, or
such other person designated by the Administrator, in escrow, pursuant to the
Joint Escrow Instructions of the Company and Holder attached as Exhibit E to the
Grant Notice, until the Company exercises its Repurchase Option as provided in
Section 3.1, until such Unreleased Shares are released from the Company's
Repurchase Option, or until such time as this Agreement no longer is in effect.
Upon release of the Unreleased Shares, the escrow agent shall deliver to Holder
the certificate or certificates representing such Shares in the escrow agent's
possession belonging to Holder in accordance with the terms of the Joint Escrow
Instructions attached as Exhibit E to the Grant Notice, and the escrow agent
shall be discharged of all further obligations hereunder; provided, however,
that the escrow agent shall nevertheless retain such certificate or certificates
as escrow agent if so required pursuant to other restrictions imposed pursuant
to this Agreement. If the Shares are held in book entry form, then such entry
will reflect that the Shares are subject to the restrictions of this Agreement.
If any dividends or other distributions are paid on the Unreleased Shares held
by the escrow agent pursuant to this Section 4.1 and the Joint Escrow
Instructions, such dividends or other distributions shall also be subject to the
restrictions set forth in this Agreement and held in escrow pending release of
the Unreleased Shares with respect to which such dividends or other
distributions were paid from the Company's Repurchase Option.

      4.2   Transfer of Repurchased Shares. Holder hereby authorizes and directs
the Secretary of the Company, or such other person designated by the
Administrator, to transfer the Unreleased Shares as to which the Repurchase
Option has been exercised from Holder to the Company.

      4.3   No Liability for Actions in Connection with Escrow. The Company, or
its designee, shall not be liable for any act it may do or omit to do with
respect to holding the Shares in escrow and while acting in good faith and in
the exercise of its judgment.

                                    ARTICLE V

                                OTHER PROVISIONS

      5.1   Adjustment for Stock Split. In the event of any stock dividend,
stock split, reverse stock split, recapitalization, combination,
reclassification, or similar change in the capital structure of the Company, the
Administrator shall make appropriate and equitable adjustments in the Unreleased
Shares subject to the Repurchase Option and the number of Shares, consistent
with any adjustment under Section 10.3 of the Plan. The provisions of this
Agreement shall apply, to the full extent set forth herein with respect to the
Shares, to any and all shares of capital stock or other securities which may be
issued in respect of, in exchange for, or in substitution of the Shares, and
shall be appropriately adjusted for any stock dividends, splits, reverse splits,
combinations, recapitalizations and the like occurring after the date hereof.

      5.2   Taxes. Holder has reviewed with Holder's own tax advisors the
federal, state, local and foreign tax consequences of this investment and the
transactions contemplated by the Grant Notice and this Agreement. Holder is
relying solely on such advisors and not on any statements or representations of
the Company or any of its agents. Holder understands that

                                      -4-
<PAGE>

Holder (and not the Company) shall be responsible for Holder's own tax liability
that may arise as a result of this investment or the transactions contemplated
by this Agreement. Holder understands that Holder will recognize ordinary income
for federal income tax purposes under Section 83 of the Code. In this context,
"restriction" includes the right of the Company to repurchase the Shares
pursuant to its Repurchase Option set forth in Section 3.1. Holder understands
that Holder may elect to be taxed for federal income tax purposes at the time
the Shares are purchased rather than as and when the Repurchase Option lapses by
filing an election under Section 83(b) of the Code with the Internal Revenue
Service within thirty (30) days from the date of purchase. A form of election
under Section 83(b) of the Code is attached to the Grant Notice as Exhibit F.

      HOLDER ACKNOWLEDGES THAT IT IS HOLDER'S SOLE RESPONSIBILITY AND NOT THE
COMPANY'S TO TIMELY FILE THE ELECTION UNDER SECTION 83(b), EVEN IF HOLDER
REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE THIS FILING ON HOLDER'S
BEHALF

      5.3   Limitations Applicable to Section 16 Persons. Notwithstanding any
other provision of the Plan or this Agreement, if Holder is subject to Section
16 of the Exchange Act, the Plan, the Shares and this Agreement shall be subject
to any additional limitations set forth in any applicable exemptive rule under
Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of the
Exchange Act) that are requirements for the application of such exemptive rule.
To the extent permitted by applicable law, this Agreement shall be deemed
amended to the extent necessary to conform to such applicable exemptive rule.

      5.4   Administration. The Administrator shall have the power to interpret
the Plan and this Agreement and to adopt such rules for the administration,
interpretation and application of the Plan as are consistent therewith and to
interpret, amend or revoke any such rules. All actions taken and all
interpretations and determinations made by the Administrator in good faith shall
be final and binding upon Holder, the Company and all other interested persons.
No member of the Administrator shall be personally liable for any action,
determination or interpretation made in good faith with respect to the Plan,
this Agreement or the Shares. In its absolute discretion, the Board may at any
time and from time to time exercise any and all rights and duties of the
Administrator under the Plan and this Agreement.

      5.5   Restrictive Legends and Stop-Transfer Orders.

            (a)   Any share certificate(s) evidencing the Shares issued
hereunder shall be endorsed with the following legend and any other legend
required by any applicable federal and state securities laws:

      THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A RIGHT OF
      REPURCHASE IN FAVOR OF THE COMPANY AND MAY BE TRANSFERRED ONLY IN
      ACCORDANCE WITH THE TERMS OF A RESTRICTED STOCK AWARD AGREEMENT BETWEEN
      THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE WITH THE
      SECRETARY OF THE COMPANY.

                                      -5-
<PAGE>

            (b)   Holder agrees that, in order to ensure compliance with the
restrictions referred to herein, the Company may issue appropriate "stop
transfer" instructions to its transfer agent, if any, and that, if the Company
transfers its own securities, it may make appropriate notations to the same
effect in its own records.

            (c)   The Company shall not be required: (i) to transfer on its
books any shares of Common Stock that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement, or (ii) to treat as owner
of such shares of Common Stock or to accord the right to vote or pay dividends
to any purchaser or other transferee to whom such shares shall have been so
transferred.

      5.6   Notices. Any notice to be given under the terms of this Agreement to
the Company shall be addressed to the Company in care of the Secretary of the
Company, and any notice to be given to Holder shall be addressed to Holder at
the address given beneath Holder's signature on the Grant Notice. By a notice
given pursuant to this Section 5.6, either party may hereafter designate a
different address for notices to be given to that party. Any notice shall be
deemed duly given when sent via email or when sent by certified mail (return
receipt requested) and deposited (with postage prepaid) in a post office or
branch post office regularly maintained by the United States Postal Service.

      5.7   Titles. Titles are provided herein for convenience only and are not
to serve as a basis for interpretation or construction of this Agreement.

      5.8   Governing Law; Severability. This Agreement shall be administered,
interpreted and enforced under the laws of the State of Delaware without regard
to conflicts of laws thereof. Should any provision of this Agreement be
determined by a court of law to be illegal or unenforceable, the other
provisions shall nevertheless remain effective and shall remain enforceable.

      5.9   Conformity to Securities Laws. Holder acknowledges that the Plan is
intended to conform to the extent necessary with all provisions of the
Securities Act and the Exchange Act and any and all regulations and rules
promulgated by the Securities and Exchange Commission thereunder, and state
securities laws and regulations. Notwithstanding anything herein to the
contrary, the Plan shall be administered, and the Shares are to be issued, only
in such a manner as to conform to such laws, rules and regulations. To the
extent permitted by applicable law, the Plan and this Agreement shall be deemed
amended to the extent necessary to conform to such laws, rules and regulations.

      5.10  Amendments. This Agreement may not be modified, amended or
terminated except by an instrument in writing, signed by Holder and by a duly
authorized representative of the Company.

      5.11  No Employment Rights. If Holder is an Employee, nothing in the Plan
or this Agreement shall confer upon Holder any right to continue in the employ
of the Company or any Subsidiary or shall interfere with or restrict in any way
the rights of the Company and its Subsidiaries, which are expressly reserved, to
discharge Holder at any time for any reason

                                      -6-
<PAGE>

whatsoever, with or without cause, except to the extent expressly provided
otherwise in a written agreement between the Company and Holder.

      5.12  Successors and Assigns. The Company may assign any of its rights
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Holder and his or her heirs, executors, administrators, successors and
assigns.

Director or Consultant of the Company or any of its Subsidiaries on the
applicable Performance Vesting Effective Date.

            (g)   Definition of Fiscal Year. For purposes of this Exhibit B, the
term "FISCAL YEAR" means the Company's fiscal year ending December 31.

            (h)   Definition of Performance Vesting Effective Date. For purposes
of this Exhibit B, the term "PERFORMANCE VESTING EFFECTIVE DATE" means, with

minimum number of Unreleased Shares that shall be released from the Company's
Repurchase Option under this subparagraph 2 on the Performance Vesting Effective
Date for Fiscal Year 2006 (with respect to EBITDA and Net Adds performance for
Fiscal Year 2006) shall be twenty percent (20%) of the total number of shares of
Restricted Stock subject to the Award (as shown in the Grant Notice).

Director or Consultant immediately prior to such Change in Control, then fifty
percent (50%) of the Unreleased Shares shall be released from the Company's
Repurchase Option, and (ii) if Holder is an Employee, Director or Consultant on
the first anniversary of the date of the occurrence of such Change in Control,
then an additional fifty percent (50%) of the Unreleased Shares shall be
released from the Company's Repurchase Option, and (iii) if the Holder is an
Employee, Director or Consultant on the second anniversary of the date of the
occurrence of such Change in Control, then any remaining Unreleased Shares shall
be released from the Company's Repurchase Option.

            (b)   Change in Control during 2006. In the event of a Change in
Control during 2006, (i) if Holder is an Employee, Director or Consultant
immediately prior to such Change in Control, then seventy-five percent (75%) of
the Unreleased Shares shall be released from the Company's Repurchase Option,
and (ii) if Holder is an Employee, Director or Consultant on the first
anniversary of the date of the occurrence of such Change in Control, then the
remaining Unreleased Shares shall be released from the Company's Repurchase
Option.

            (c)   Change in Control on or after January 1 2007. In the event of
a Change in Control on or after January 1, 2007, if Holder is an Employee,
Director or Consultant immediately prior to such Change in Control, then
eighty-five percent (85%) of the Unreleased Shares shall be released from the
Company's Repurchase Option and (ii) if the Holder is an Employee, Director or
Consultant on the first anniversary of the date of occurrence of such change in
Control, then any then remaining Unreleased Shares shall be released from the
Company's Repurchase Option.

            (d)   Termination of Employment in the Event of a Change in Control.
In the event of a Change in Control, if Holder has a Termination of Employment
by reason of discharge by the Company other than for Cause (as defined below),
or by reason of resignation by Holder for Good Reason (as defined below), during
the period commencing ninety (90) days prior to such Change in Control and
ending twelve (12) months after such Change in Control, then (i) if the Change
in Control occurs prior to January 1, 2006, twenty-five percent (25%) of the
Unreleased Shares shall be released form the Company's Repurchase Option and
(ii) if the Change in Control occurs on or after January 1, 2006, the remaining
Unreleased Shares shall be released from the Company's Repurchase Option, in
each case, on the date of Holder's Termination of Employment (or, if later,
immediately prior to the date of the occurrence of such Change in Control).

      4.    Accelerated Vesting in the Event of Termination of Employment.

            (a)   Accelerated Vesting in the Event of Termination of Employment
by the Company Other than for Cause or by Holder for Good Reason After February
28, 2006. In the event of Holder's Termination of Employment by reason of
discharge by the Company other than for Cause, or by reason of resignation by
the Holder for Good Reason after February 28, 2006, (i) if the Holder, upon
written request of the Company and reasonable advance notice, agrees to provide,
and does provide, consulting services to the Company (or to the Parent at the

                                      -5-
<PAGE>

direction of the Company, or both) for up to five (5) days a month for up to a
one (1) year period for a fee of $1,500 per day, the remaining Unreleased Shares
shall be released from the Company's Repurchase Option on the last day of the
one year period, or (ii) such remaining Unreleased Shares shall otherwise be
released from the Company's Repurchase Option on the third anniversary of the
Grant Date. The Company and the Holder shall mutually use their best efforts to
schedule the date or dates on which the Holder will provide the requested
consulting services so as not to prevent the Holder from being gainfully
employed by a subsequent employer, and shall be arranged so as to reasonably
accommodate Holder's vacation or other personal affairs.

            (b)   Definitions of Cause and Good Reason. For purposes of this
Exhibit B, the terms "CAUSE" and "GOOD REASON" shall have the meanings given to
such terms in that certain Executive Employment Agreement dated as of January
10, 2005, by and between Holder, the Company and Cricket Communications, Inc.,
as amended from time to time (the "EMPLOYMENT AGREEMENT").

            (c)   Condition to Release of Shares. The release of Unreleased
Shares from the Company's Repurchase Option pursuant to this paragraph 4 shall
be conditioned on the Holder's delivery to the Company of an executed General
Release in accordance with Section 5.9 of the Employment Agreement and the
Holder's non-revocation of such General Release during the time period for such
revocation set forth therein.

      5.    Limit on Release of Shares. In no event will more than 100% of the
Unreleased Shares be released from the Company's Repurchase Option pursuant to
the provisions of this Exhibit B.

      6.    Confidentiality. The Holder agrees to keep the EBITDA and Net Adds
achievement levels set forth in this Exhibit B confidential and not to disclose
such thresholds to any third party without the prior written consent of the
Company.

</TABLE>

The EBITDA amounts in the following examples are shown in thousands.

Example 1:

-     2005 EBITDA: [***]

-     2005 Net Adds: [***]

      PROBLEM: The net adds performance falls exactly on a specified payout
range, but performance in EBITDA falls somewhere in-between the schedule.

      SOLUTION: Start with the net adds payout column and use straight-line
interpolation to determine the final payout.

      PAYOUT CALCULATION: Net additions of [***] dictate a payout of 12.5% for
threshold EBITDA performance and 20% for target EBITDA performance. Since EBITDA
performance ([***]) is halfway between THRESHOLD and TARGET performance ([***]
and [***]), the actual payout should be halfway between the scheduled payouts of
12.5% and 20%. Thus the payout is (1/2)*(20%-12.5%)+12.5%

-     Payout = 16.25%

Example 2:

-     2005 EBITDA: [***]

-     2005 Net Adds: [***]

<PAGE>

      PROBLEM: Neither the net adds performance nor the EBITDA performance fall
exactly on a specified payout.

      SOLUTION: Use straight line interpolation for both measures. Starting with
either measure will yield the same result.

      PAYOUT CALCULATION: EBITDA performance ([***]) is halfway between
THRESHOLD and TARGET performance ([***] and [***]), so we can interpolate an
EBITDA-based payout schedule by finding the halfway point at each defined level
of Net Adds. At [***] net adds, the EBITDA-based payout would be halfway between
10% and 12.5%. At [***] net adds, the EBITDA-based payout would be halfway
between 12.5% and 20%. At [***] net adds, the EBITDA-based payout would be
halfway between 15% and 22.5%. Thus the interpolated, EBITDA-based payout
schedule looks like this:

                  (midpoint of [***]  10% and         12.5% and           15% and
                  and [***])          12.5%)          20%)                22.5%)
</TABLE>

      To determine the actual payout given this range, we interpolate a payout
at [***] net adds based on the scheduled payouts at [***] and [***]. First we
determine where [***] lies in the range of [***] to [***]. The length of the
range is [***] - [***] = [***] net adds. [***] is [***] above the range minimum
([***] - [***] = [***]). So the actual performance of [***] net adds falls 1/3
of the way between [***] net adds (target) and [***] net adds (maximum). This
means the actual payout must fall 1/3 of the way between 16.25% and 18.75%. Thus
the payout is (1/3)*(18.75%-16.25%)+16.25%

-     Payout = 17.08%

Ladies and Gentlemen:

      As escrow agent (the "ESCROW AGENT") for both Leap Wireless International,
Inc., a Delaware corporation (the "COMPANY"), and the undersigned recipient of
stock of the Company (the "HOLDER"), you are hereby authorized and directed to
hold in escrow the documents delivered to you pursuant to the terms of that
certain Restricted Stock Award Agreement ("AGREEMENT") between the Company and
the undersigned (the "Escrow"), including the stock certificate and the
Assignment in Blank, in accordance with the following instructions:

      1.    In the event the Company and/or any assignee of the Company
(referred to collectively for convenience herein as the "COMPANY") exercises the
Company's Repurchase Option as defined in the Agreement), the Company shall give
to the Holder and you a written notice specifying the number of shares of stock
to be purchased, the purchase price and the time for a closing hereunder at the
principal office of the Company. The Holder and the Company hereby irrevocably
authorize and direct you to close the transaction contemplated by such notice in
accordance with the terms of said notice.

      2.    As of the date of closing of the repurchase indicated in such
notice, you are directed (a) to date the stock assignments necessary for the
repurchase and transfer in question, (b) to fill in the number of shares being
repurchased and transferred, and (c) to deliver the same, together with the
certificate evidencing the shares of stock to be repurchased and transferred, to
the Company or its assignee.

      3.    Holder irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to said shares as defined in the Agreement. Holder
does hereby irrevocably constitute and appoint you as Holder's attorney-in-fact
and agent for the term of this escrow to execute with respect to such securities
all documents necessary or appropriate to make such securities negotiable and to
complete any transaction herein contemplated, including but not limited to the
filing with any applicable state blue sky authority of any required applications
for consent to, or notice of transfer of, the securities. Subject to the
provisions of this paragraph and the Agreement, Holder shall exercise all rights
and privileges of a stockholder of the Company while the stock is held by you.

                                      -1-
<PAGE>

      4.    Upon written request of Holder, but no more than once per calendar
month, unless the Company's Repurchase Option has been exercised, you will
deliver to Holder a certificate or certificates representing so many shares of
stock as are not then subject to the Repurchase Option. Within one hundred
twenty (120) days after any voluntary or involuntary termination of Holder's
services to the Company for any or no reason, you will deliver to Holder a
certificate or certificates representing the aggregate number of shares held or
issued pursuant to the Agreement and not repurchased pursuant to the Repurchase
Option set forth in Section 3.1 of the Agreement.

      5.    If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to Holder, you
shall deliver all of the same to the Holder and shall be discharged of all
further obligations hereunder.

      6.    Your duties hereunder may be altered, amended, modified or revoked
only by a writing signed by all of the parties hereto.

shall not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact for Holder while acting in good faith, and
any act done or omitted by you pursuant to the advice of your own attorneys
shall be conclusive evidence of such good faith.

      8.    You are hereby expressly authorized to disregard any and all
warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law and are hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case you obey or comply with any such order, judgment or decree, you
shall not be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

      12.   Your responsibilities as Escrow Agent hereunder shall terminate if
you shall cease to be an officer or agent of the Company or if you shall resign
by written notice to each party. In the event of any such termination, the
Company shall appoint a successor Escrow Agent.

      13.   If you reasonably require other or further instruments in connection
with these Joint Escrow Instructions or obligations in respect hereto, the
necessary parties hereto shall join in furnishing such instruments.

      14.   It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the
securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such disputes shall have been settled either by mutual written agreement
of the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

      4.1   Person Eligible to Exercise. Except as provided in Sections 5.2(b)
and 5.2(c), during the lifetime of Holder, only Holder may exercise the Option
or any portion thereof. After the death of Holder, any exercisable portion of
the Option may, prior to the time when the Option becomes unexercisable under
Section 3.3, be exercised by Holder's personal representative or by any person
empowered to do so under the deceased Holder's will or under the then applicable
laws of descent and distribution.

      4.2   Partial Exercise. Any exercisable portion of the Option or the
entire Option, if then wholly exercisable, may be exercised in whole or in part
at any time prior to the time when the Option or portion thereof becomes
unexercisable under Section 3.3.

                                      -2-
<PAGE>

      4.3   Manner of Exercise. The Option, or any exercisable portion thereof,
may be exercised solely by delivery to the Secretary of the Company or the
Secretary's office of all of the following prior to the time when the Option or
such portion thereof becomes unexercisable under Section 3.3:

            (a)   An Exercise Notice in writing signed by Holder or any other
person then entitled to exercise the Option or portion thereof, stating that the
Option or portion thereof is thereby exercised, such notice complying with all
applicable rules established by the Administrator. Such notice shall be
substantially in the form attached as Exhibit C to the Grant Notice (or such
other form as is prescribed by the Administrator); and

            (b)   Subject to Section 6.2(d) of the Plan:

                  (i)   Full payment (in cash or by check) for the shares with
respect to which the Option or portion thereof is exercised; or

                  (ii)  With the consent of the Administrator, such payment may
be made, in whole or in part, through the delivery of shares of Common Stock
which have been owned by Holder for at least six (6) months, duly endorsed for
transfer to the Company with a Fair Market Value on the date of delivery equal
to the aggregate exercise price of the Option or exercised portion thereof; or

                  (iii) To the extent permitted under applicable laws, through
the delivery of a notice that Holder has placed a market sell order with a
broker with respect to shares of Common Stock then issuable upon exercise of the
Option, and that the broker has been directed to pay a sufficient portion of the
net proceeds of the sale to the Company in satisfaction of the Option exercise
price, provided, that payment of such proceeds is made to the Company upon
settlement of such sale; or

                  (iv)  With the consent of the Administrator, any combination
of the consideration provided in the foregoing paragraphs (i), (ii) and (iii);
and

            (c)   A bona fide written representation and agreement, in such form
as is prescribed by the Administrator, signed by Holder or the other person then
entitled to exercise such Option or portion thereof, stating that the shares of
Common Stock are being acquired for Holder's own account, for investment and
without any present intention of distributing or reselling said shares or any of
them except as may be permitted under the Securities Act and then applicable
rules and regulations thereunder, and that Holder or other person then entitled
to exercise such Option or portion thereof will indemnify the Company against
and hold it free and harmless from any loss, damage, expense or liability
resulting to the Company if any sale or distribution of the shares by such
person is contrary to the representation and agreement referred to above. The
Administrator may, in its absolute discretion, take whatever additional actions
it deems appropriate to ensure the observance and performance of such
representation and agreement and to effect compliance with the Securities Act
and any other federal or state securities laws or regulations. Without limiting
the generality of the foregoing, the Administrator may require an opinion of
counsel acceptable to it to the effect that any subsequent transfer of shares
acquired on an Option exercise does not violate the Securities Act,

                                      -3-
<PAGE>

and may issue stop-transfer orders covering such shares. Share certificates
evidencing Common Stock issued on exercise of the Option shall bear an
appropriate legend referring to the provisions of this subsection (c) and the
agreements herein. The written representation and agreement referred to in the
first sentence of this subsection (c) shall, however, not be required if the
shares to be issued pursuant to such exercise have been registered under the
Securities Act, and such registration is then effective in respect of such
shares; and

            (d)   The receipt by the Company of full payment for such shares,
including payment of any applicable withholding tax, which in the discretion of
the Administrator may be in the form of consideration used by Holder to pay for
such shares under Section 4.3(b), subject to Section 10.4 of the Plan; and

            (e)   In the event the Option or portion thereof shall be exercised
pursuant to Section 4.1 by any person or persons other than Holder, appropriate
proof of the right of such person or persons to exercise the Option.

      4.4   Conditions to Issuance of Stock Certificates. The shares of Common
Stock deliverable upon the exercise of the Option, or any portion thereof, may
be either previously authorized but unissued shares or issued shares which have
then been reacquired by the Company. Such shares shall be fully paid and
nonassessable. The Company shall not be required to issue or deliver any shares
of Common Stock purchased upon the exercise of the Option or portion thereof
prior to fulfillment of all of the following conditions:

            (a)   The admission of such shares to listing on all stock exchanges
on which such Common Stock is then listed; and

            (b)   The completion of any registration or other qualification of
such shares under any state or federal law or under rulings or regulations of
the Securities and Exchange Commission or of any other governmental regulatory
body, which the Administrator shall, in its absolute discretion, deem necessary
or advisable; and

            (c)   The obtaining of any approval or other clearance from any
state or federal governmental agency which the Administrator shall, in its
absolute discretion, determine to be necessary or advisable; and

            (d)   The lapse of such reasonable period of time following the
exercise of the Option as the Administrator may from time to time establish for
reasons of administrative convenience; and

            (e)   The receipt by the Company of full payment for such shares,
including payment of any applicable withholding tax, which in the discretion of
the Administrator may be in the form of consideration used by the Holder to pay
for such shares under Section 4.3(b), subject to Section 10.4 of the Plan.

      4.5   Rights as Stockholder. Holder of the Option shall not be, nor have
any of the rights or privileges of, a stockholder of the Company in respect of
any shares purchasable upon the exercise of any part of the Option unless and
until such shares shall have been issued by the Company to such holder.

                                OTHER PROVISIONS

      5.1   Administration. The Administrator shall have the power to interpret
the Plan and this Agreement and to adopt such rules for the administration,
interpretation and application of the Plan as are consistent therewith and to
interpret, amend or revoke any such rules. All actions taken and all
interpretations and determinations made by the Administrator in good faith shall
be final and binding upon Holder, the Company and all other interested persons.
No member of the Administrator shall be personally liable for any action,
determination or interpretation made in good faith with respect to the Plan,
this Agreement or the Option. In its absolute discretion, the Board may at any
time and from time to time exercise any and all rights and duties of the
Administrator under the Plan and this Agreement.

      5.2   Option Not Transferable.

            (a)   Subject to Section 5.2(b), the Option may not be sold,
pledged, assigned or transferred in any manner other than by will or the laws of
descent and distribution or, subject to the consent of the Administrator,
pursuant to a DRO, unless and until the shares underlying the Option have been
issued, and all restrictions applicable to such shares have lapsed. Neither the
Option nor any interest or right therein shall be liable for the debts,
contracts or engagements of Holder or his or her successors in interest or shall
be subject to disposition by transfer, alienation, anticipation, pledge,
encumbrance, assignment or any other means whether such disposition be voluntary
or involuntary or by operation of law by judgment, levy, attachment, garnishment
or any other legal or equitable proceedings (including bankruptcy), and any
attempted disposition thereof shall be null and void and of no effect, except to
the extent that such disposition is permitted by the preceding sentence.

            (b)   Notwithstanding any other provision in this Agreement, with
the consent of the Administrator and to the extent the Option is not intended to
qualify as an Incentive Stock Option, the Option may be transferred to one or
more Permitted Transferees, subject to the terms and conditions set forth in
Section 10.1 of the Plan.

            (c)   Unless transferred to a Permitted Transferee in accordance
with Section 5.2(b), during the lifetime of Holder, only Holder may exercise the
Option or any portion thereof unless it has been disposed of pursuant to a DRO.
After the death of Holder, any exercisable portion of the Option may, prior to
the time when the Option becomes unexercisable under Section 3.3, be exercised
by Holder's personal representative or by any person empowered to do so under
the deceased Holder's will or under the then applicable laws of descent and
distribution.

      5.3   Restrictive Legends and Stop-Transfer Orders.

            (a)   The share certificate or certificates evidencing the shares of
Common Stock purchased hereunder shall be endorsed with any legends that may be
required by state or federal securities laws.

            (b)   Holder agrees that, in order to ensure compliance with the
restrictions referred to herein, the Company may issue appropriate "stop
transfer" instructions to its transfer

                                      -5-

agent, if any, and that, if the Company transfers its own securities, it may
make appropriate notations to the same effect in its own records.

            (c)   The Company shall not be required: (i) to transfer on its
books any shares of Common Stock that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement, or (ii) to treat as owner
of such shares of Common Stock or to accord the right to vote or pay dividends
to any purchaser or other transferee to whom such shares shall have been so
transferred.

      5.4   Shares to Be Reserved. The Company shall at all times during the
term of the Option reserve and keep available such number of shares of Common
Stock as will be sufficient to satisfy the requirements of this Agreement.

      5.5   Notices. Any notice to be given under the terms of this Agreement to
the Company shall be addressed to the Company in care of the Secretary of the
Company, and any notice to be given to Holder shall be addressed to Holder at
the address given beneath Holder's signature on the Grant Notice. By a notice
given pursuant to this Section 5.5, either party may hereafter designate a
different address for notices to be given to that party. Any notice which is
required to be given to Holder shall, if Holder is then deceased, be given to
the person entitled to exercise his or her Option pursuant to Section 4.1 by
written notice under this Section 5.5. Any notice shall be deemed duly given
when sent via email or when sent by certified mail (return receipt requested)
and deposited (with postage prepaid) in a post office or branch post office
regularly maintained by the United States Postal Service.

      5.6   Titles. Titles are provided herein for convenience only and are not

intended to conform to the extent necessary with all provisions of the
Securities Act and the Exchange Act and any and all regulations and rules
promulgated by the Securities and Exchange Commission thereunder, and state
securities laws and regulations. Notwithstanding anything herein to the
contrary, the Plan shall be administered, and the Option is granted and may be

Agreement shall be deemed amended to the extent necessary to conform to such

terminated except by an instrument in writing, signed by Holder or such other
person as may be permitted to exercise the Option pursuant to Section 4.1 and by
a duly authorized representative of the Company.

      5.10  No Employment Rights. If Holder is an Employee, nothing in the Plan

of the Company or any Subsidiary or shall interfere with or restrict in any way
the rights of the Company and its Subsidiaries, which are expressly reserved, to
discharge Holder at any time for any reason whatsoever, with or without cause,

                          TO STOCK OPTION GRANT NOTICE

                      VESTING AND EXERCISABILITY PROVISIONS

      Capitalized terms used in this Exhibit B and not defined below shall have
the meanings given them in the Grant Notice and the Stock Option Agreement.

      1.    Time-Based Vesting. Subject to any accelerated vesting and
exercisability pursuant to paragraphs 2, 3 and 4 below, the shares of Common
Stock subject to the Option shall vest and become exercisable in their entirety
on the third anniversary of the Grant Date, if Holder is an Employee, Director
or Consultant on that date.

      2.    Performance-Based Accelerated Vesting. If the Company's EBITDA (as
defined below) and the Company's Net Adds (as defined below) both equal or
exceed the respective Achievement Threshold amounts for 2005 as set forth in
paragraph (a) below and/or both equal or exceed the Achievement Threshold
amounts for 2006 as set forth in paragraph (b) below, then a certain percentage
of the number of shares of Common Stock subject to the Option shall vest and
become exercisable in accordance with the provisions of paragraphs (a) and (b)
below; provided, however, that no shares subject to the Option shall vest and
become exercisable pursuant to paragraphs (a) or (b) below, if either the
Company's EBITDA or Net Adds do not at least equal the Achievement Threshold
amount for the applicable year.

            (a)   Fiscal Year 2005. If the Company's EBITDA (as defined below)
and Net Adds (as defined below) for Fiscal Year 2005 equal or exceed the EBITDA
and Net Adds Achievement Thresholds (as set forth below), then the Option shall
vest and become exercisable as to that number of shares of Common Stock equal to
the number obtained by multiplying the percentage determined in accordance with
the following table, by the total number of shares of Common Stock subject to
the Option (as set forth in the Grant Notice).

            (d)   Definition of Net Adds. For purposes of this Exhibit B, the
term "NET ADDS" means, with respect to any Fiscal Year, the Company's "end of
period customers" on the last day of such Fiscal Year less "end of period

pre-paid card based service offering, the Administrator shall, in its
discretion, equitably adjust the Net Adds Achievement Levels set forth in
paragraphs (a) and (b) to reflect the Company's changed scope of operations.

            (e)   Adjustments for Future Changes in the Company's Business. The
EBITDA Achievement Levels and Net Adds Achievement Levels set forth in
paragraphs (a) and (b) are designed to be measured against the Company's
performance in its existing thirty-nine (39) markets. If the Company commences
operations in any new markets, or ceases to operate in any existing market, the
Administrator shall, in its discretion, equitably adjust the EBITDA Achievement
Levels and/or the Net Adds Achievement Levels to reflect the Company's changed
scope of operations.

            (f)   Accelerated Vesting Cumulative; Continued Service Condition.
The vesting and exercisability of the Option as to shares of Common Stock under
paragraphs 2(a) and 2(b) shall be cumulative. Except as otherwise provided in
subparagraph 2(j), the Option shall vest and become exercisable as to shares of
Common Stock pursuant to this paragraph 2 if Holder is an Employee, Director or
Consultant of the Company or any of its Subsidiaries on the applicable
Performance Vesting Effective Date.

relevant Fiscal Year, but in no event shall the Company make such public
announcement later than the date on which the Company files its Form 10-K for
the relevant Fiscal Year.

            (h)   Definition of Fiscal Year. For purposes of this Exhibit B, the
term "FISCAL YEAR" means the Company's fiscal year ending December 31.

performance-based accelerated vesting and exercisability under this paragraph 2
on or after the date of the occurrence of a Change in Control.

            (j)   Minimum Vesting For Fiscal Year 2006. Notwithstanding the
other provisions of this paragraph 2 (other than subparagraph 2(i)), if Holder
is an Employee, Director or Consultant on December 31, 2005, then the minimum
additional number of shares of Common Stock that shall vest and become
exercisable under this paragraph 2 on the Performance Vesting Effective Date for

The EBITDA amounts in the following examples are shown in thousands.

Example 1:

-     2005 EBITDA: [***]

-     2005 Net Adds: [***]

      PROBLEM: The net adds performance falls exactly on a specified payout
range, but performance in EBITDA falls somewhere in-between the schedule.

      SOLUTION: Start with the net adds payout column and use straight-line
interpolation to determine the final payout.

      PAYOUT CALCULATION: Net additions of [***] dictate a payout of 12.5% for
threshold EBITDA performance and 20% for target EBITDA performance. Since EBITDA
performance ([***]) is halfway between THRESHOLD and TARGET performance ([***]
and [***]), the actual payout should be halfway between the scheduled payouts of
12.5% and 20%. Thus the payout is (1/2)*(20%-12.5%)+12.5%

-     Payout = 16.25%

Example 2:

-     2005 EBITDA: [***]

-     2005 Net Adds: [***]

<PAGE>

      PROBLEM: Neither the net adds performance nor the EBITDA performance fall
exactly on a specified payout.

      SOLUTION: Use straight line interpolation for both measures. Starting with
either measure will yield the same result.

      PAYOUT CALCULATION: EBITDA performance ([***]) is halfway between
THRESHOLD and TARGET performance ([***] and [***]), so we can interpolate an
EBITDA-based payout schedule by finding the halfway point at each defined level
of Net Adds. At [***] net adds, the EBITDA-based payout would be halfway between
10% and 12.5%. At [***] net adds, the EBITDA-based payout would be halfway
between 12.5% and 20%. At [***] net adds, the EBITDA-based payout would be
halfway between 15% and 22.5%. Thus the interpolated, EBITDA-based payout
schedule looks like this:

              Actual                     11.25%               16.25%                18.75%
2005          [***]                      (midpoint of 10%     (midpoint of 12.5%    (midpoint of 15%
EBITDA        (midpoint of [***] and     and 12.5%)           and 20%)              and 22.5%)
              [***])
----------------------------------------------------------------------------------------------------
</TABLE>

      To determine the actual payout given this range, we interpolate a payout
at [***] net adds based on the scheduled payouts at [***] and [***]. First we
determine where [***] lies in the range of [***] to [***]. The length of the
range is [***] - [***] = [***] net adds. [***] is [***] above the range minimum
([***] - [***] = [***]). So the actual performance of [***] net adds falls 1/3
of the way between [***] net adds (target) and [***] net adds (maximum). This
means the actual payout must fall 1/3 of the way between 16.25% and 18.75%. Thus
the payout is (1/3)*(18.75%-16.25%)+16.25%

-     Payout = 17.08%

             GRANT, VESTING AND DISTRIBUTION OF DEFERRED STOCK UNITS

and/or continued employment with or service to the Company or its Subsidiaries
and for other good and valuable consideration, effective as of the Grant Date

<PAGE>

the Plan and this Agreement, for a period of thirty (30) days commencing
following the earliest to occur of the following events (each, a "DISTRIBUTION
EVENT"):

                  (i)   the date Holder has a Termination of Employment,
      Termination of Consultancy or Termination of Directorship, as applicable;

                  (ii)  the date immediately prior to a Change in Control; or

                  (iii) August 15, 2005.

            (b)   Following a Distribution Event, Holder may purchase the shares
of Common Stock issuable with respect to his or her vested Deferred Stock Units
by delivery to the Secretary of the Company or the Secretary's office of all of
the following within thirty (30) days following the occurrence of the
Distribution Event.

                  (i)   A Purchase Notice in writing signed by the Holder or any
      other person then entitled to purchase the shares of Common Stock issuable
      with respect to the vested Deferred Stock Units, stating that such shares
      of Common Stock are being purchased, such notice complying with all
      applicable rules established by the Administrator. Such notice shall be
      substantially in the form attached as Exhibit B to the Grant Notice (or
      such other form as is prescribed by the Administrator); and

                  (ii)  Full payment (in cash or by check) for the shares of
      Common Stock to be purchased by Holder, including payment of any
      applicable withholding tax, which in the discretion of the Administrator
      may be in any form permitted by Section 10.4 of the Plan; and

                  (iii) A bona fide written representation and agreement, in
      such form as is prescribed by the Administrator, signed by Holder or the
      other person then entitled to purchase the shares of Common Stock issuable
      with respect to the vested Deferred Stock Units, stating that the shares
      of Common Stock are being acquired for Holder's own account, for
      investment and without any present intention of distributing or reselling
      said shares or any of them except as may be permitted under the Securities
      Act and then applicable rules and regulations thereunder, and that Holder
      or the other person then entitled to purchase the shares of Common Stock
      issuable with respect to the vested Deferred Stock Units will indemnify
      the Company against and hold it free and harmless from any loss, damage,
      expense or liability resulting to the Company if any sale or distribution
      of the shares by such person is contrary to the representation and
      agreement referred to above. The Administrator may, in its absolute
      discretion, take whatever additional actions it deems appropriate to
      ensure the observance and performance of such representation and agreement
      and to effect compliance with the Securities Act and any other federal or
      state securities laws or regulations. Without limiting the generality of
      the foregoing, the Administrator may require an opinion of counsel
      acceptable to it to the effect that any subsequent transfer of shares
      acquired by Holder does not violate the Securities Act, and may issue
      stop-transfer orders covering such shares. Share certificates evidencing
      Common Stock issued pursuant to the Deferred Stock Units shall bear an
      appropriate legend referring to the provisions of this subsection (c) and
      the agreements

                                      -2-
<PAGE>

      herein. The written representation and agreement referred to in the first
      sentence of this subsection (c) shall, however, not be required if the
      shares to be issued pursuant to such exercise have been registered under
      the Securities Act, and such registration is then effective in respect of
      such shares; and

                  (iv)  In the event the shares of Common Stock issuable with
      respect to the vested Deferred Stock Units shall be purchased pursuant to
      this Section 2.4(b) by any person or persons other than Holder,
      appropriate proof of the right of such person or persons to purchase such
      shares of Common Stock.

            (c)   Subject to the conditions of Sections 2.4(b) and 2.6, the
Company shall distribute any shares of Common Stock purchased pursuant to this
Section 2.4(b) in a single lump sum distribution. If Holder does not purchase
the shares of Common Stock issuable with respect to any vested Deferred Stock
Units within thirty (30) days following the occurrence of a Distribution Event,
such Deferred Stock Units shall terminate.

            (d)   All distributions shall be made by the Company in the form of
whole shares of Common Stock (and cash in an amount equal to the value of any
fractional Deferred Stock Unit, determined based on the Fair Market Value as of
the distribution date).

            (e)   Neither the time nor form of distribution of the Deferred
Stock Units under this Agreement may be changed, except as may be provided under
the Plan.

            (f)   Notwithstanding the foregoing, shares of Common Stock shall be
issuable pursuant to a Deferred Stock Unit at such times and upon such events as
are specified in this Agreement only to the extent issuance under such terms
will not cause the Deferred Stock Units or the shares of Common Stock issuable
pursuant to the Deferred Stock Units to be includible in the gross income of
Holder under Section 409A of the Code prior to such times or the occurrence of
such events, as permitted by the Code and the regulations and other guidance
thereunder.

      2.5   Restrictions on Transfer. Unless otherwise permitted by the
Administrator pursuant to the Plan, no Deferred Stock Units or shares of Common
Stock issuable with respect thereto or any interest or right therein or part
thereof shall be liable for the debts, contracts or engagements of the Holder or
his successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect.

      2.6   Conditions to Issuance of Stock Certificates. The shares of Common
Stock deliverable with respect to the Deferred Stock Units, or any portion
thereof, may be either previously authorized but unissued shares or issued
shares which have then been reacquired by the Company. Such shares shall be
fully paid and nonassessable. The Company shall not be required to issue or
deliver any shares of Common Stock with respect to the Deferred Stock Units
prior to fulfillment of all of the following conditions:

            (a)   The admission of such shares to listing on all stock exchanges
on which such Common Stock is then listed; and

                                      -3-
<PAGE>

            (b)   The completion of any registration or other qualification of
such shares under any state or federal law or under rulings or regulations of
the Securities and Exchange Commission or of any other governmental regulatory
body, which the Administrator shall, in its absolute discretion, deem necessary
or advisable; and

            (c)   The obtaining of any approval or other clearance from any
state or federal governmental agency which the Administrator shall, in its
absolute discretion, determine to be necessary or advisable; and

            (d)   The lapse of such reasonable period of time following the
applicable Distribution Event as the Administrator may from time to time
establish for reasons of administrative convenience; and

            (e)   The receipt by the Company of full payment for such shares,
including payment of all amounts which, under federal, state or local tax law,
the Company (or other employer corporation) is required to withhold upon
issuance of such shares in accordance with Section 10.4 of the Plan.

      2.7   Rights as Stockholder. Except as otherwise provided herein, the
Holder shall not be, nor have any of the rights or privileges of, a stockholder
of the Company in respect of any shares issuable pursuant to the Deferred Stock
Units unless and until such shares shall have been issued by the Company to
Holder.

to the issuance or distribution of the Deferred Stock Units or shares of Common
Stock issuable with respect thereto. The Company shall not be obligated to
deliver any new certificate representing shares of Common Stock issuable with
respect to the Deferred Stock Units to Holder or his legal representative unless
and until Holder or his legal representative shall have paid or otherwise
satisfied in full the amount of all federal,

                                      -4-

the Plan and this Agreement and to adopt such rules for the administration,
interpretation and application of the Plan as are consistent therewith and to
interpret, amend or revoke any such rules. All actions taken and all

            (a)   Any share certificate(s) evidencing the shares of Common Stock
issued hereunder shall be endorsed with any legend required by any applicable
federal and state securities laws.

            (b)   Holder agrees that, in order to ensure compliance with the
restrictions referred to herein, the Company may issue appropriate "stop
transfer" instructions to its transfer agent, if any, and that, if the Company
transfers its own securities, it may make appropriate notations to the same
effect in its own records.

            (c)   The Company shall not be required: (i) to transfer on its
books any shares of Common Stock that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement, or (ii) to treat as owner
of such shares of Common Stock or to accord the right to vote or pay dividends

intended to conform to the extent necessary with all provisions of the
Securities Act and the Exchange Act and any and all regulations and rules
promulgated by the Securities and Exchange Commission thereunder, and state
securities laws and regulations. Notwithstanding anything herein to the
contrary, the Plan shall be administered, and the Deferred Stock Units are
granted, only in such a manner as to conform to such laws, rules and
regulations. To the extent permitted by applicable law, the Plan and this
Agreement shall be deemed amended to the extent necessary to conform to such
laws, rules and regulations.

terminated except by an instrument in writing, signed by Holder and by a duly
authorized representative of the Company.

discharge Holder at any time for any reason whatsoever, with or without cause,
except to the extent expressly provided otherwise in a written agreement between
the Company and Holder.

      3.12  Successors and Assigns. The Company may assign any of its rights
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Holder and his or her heirs, executors, administrators, successors and
assigns.

      3.13  Unfunded, Unsecured Obligations. The obligations of the Company
under the Plan and this Agreement shall be unfunded and unsecured, and nothing

benefit of Holder or any other person. Holder shall have only the rights of a
general, unsecured creditor of the Company with respect to the Deferred Stock
Units, unless and until shares of Common Stock shall be distributed to Holder
under the terms and conditions of this Agreement.

forever discharge the Company, the Parent, their subsidiaries, and their
respective stockholders, officers, directors, any of the directors' affiliated
entities, managers, employees, representatives, related entities, successors and
assigns, and all persons acting by, through or in concert with them (the
"Releasees") of and from any and all claims, actions, charges, complaints,
causes of action, rights, demands, debts, damages, or accountings of whatever
nature, known or unknown, which EXECUTIVE may have against the Releasees based
on any actions or events which occurred prior to the date of this General

      A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH A CREDITOR DOES NOT KNOW
      OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE,
      WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH
      THE DEBTOR.

      3.    OLDER WORKER'S BENEFIT PROTECTION ACT. EXECUTIVE AGREES AND
EXPRESSLY ACKNOWLEDGES THAT THIS GENERAL RELEASE INCLUDES A WAIVER AND RELEASE

incurred as a result of any person asserting any such assignment or transfer of

the payment of money nor the execution of this Release shall constitute or be
construed as an admission of any liability whatsoever by the Releasees.
