parties hereto hereby agree as follows:

        principal thereof be due, nor shall such Indebtedness be subject to any
        mandatory redemption or required repurchase, conversion or exchange
        (whether upon the occurrence of any contingency or otherwise, but

        the net proceeds of such Indebtedness (other than the portion, if any,

        Subsidiary prior to September 30, 2000; provided that all proceeds
        described in this clause (ii) shall be held in an interest-bearing
        account until so used and, to the extent such proceeds and the accrued
        interest thereon are not used to purchase FCC Licenses prior to

        repaid or prepaid by the Borrower and the Subsidiary Loan Parties during
        such fiscal year, excluding (i) Eligible Secured Debt prepaid pursuant
        to Section 2.09(c) or (d), and (ii) repayments or prepayments of

                            DESCRIPTION OF THE NOTES

     The Senior Notes and the Senior Discount Notes will be issued under an
Indenture, to be dated as of the Closing Date (the "Indenture"), between the
Company, as issuer, the Guarantor and State Street Bank and Trust Company, as
Trustee (the "Trustee"). The Senior Notes and the Senior Discount Notes are
collectively referred to as the "Notes." A copy of the Indenture is available
upon request from the Company. The following summary of certain provisions of
the Indenture does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all the provisions of the Indenture,
the Notes and the Guarantee, including the definitions of certain terms therein
and those terms made a part thereof by reference to the Trust Indenture Act of
1939, as amended. Whenever particular defined terms of the Indenture not
otherwise defined herein are referred to, such defined terms are incorporated
herein by reference. For definitions of certain capitalized terms used in the
following summary, see "-- Certain Definitions." For purposes of the Description
of Notes, references to the "Company" are references solely to Leap Wireless
International, Inc. and do not include the Company's subsidiaries, except for
purposes of financial data determined on a consolidated basis.

GENERAL

     MATURITY, INTEREST AND PRINCIPAL OF THE SENIOR NOTES

     The Senior Notes will be initially limited to $225 million aggregate
principal amount, and will mature on April 15, 2010. Each Senior Note will
initially bear interest at the rate shown on the front cover of this Memorandum
from the Closing Date or from the most recent Interest Payment Date to which
interest has been paid or provided for, payable semiannually in arrears on April
15 and October 15 of each year, commencing April 15, 2000, to Holders of record
at the close of business on the April 1 or October 1 immediately preceding the
Interest Payment Date. Interest payments due on the first seven Interest Payment
Dates for the Senior Notes will be secured by amounts on deposit in the Pledge
Account described below. See "-- Security" below. See "-- Registration Rights"
for a description of the circumstances under which the interest rate on the
Notes may be increased.

     The Company may, subject to the covenants described below under
"-- Covenants" and applicable law, issue additional Senior Notes under the
Indenture having identical terms and conditions to the Senior Notes offered
hereby. The Senior Notes offered hereby and any additional Senior Notes
subsequently issued would be treated as a single class for all purposes of the
Indenture.

     MATURITY, INTEREST AND PRINCIPAL OF THE SENIOR DISCOUNT NOTES

     The Senior Discount Notes will be initially limited to $668 million
aggregate principal amount at maturity, and will mature on April 15, 2010. The
Senior Discount Notes are being offered at a discount from their aggregate
principal amount at maturity, with the initial Accreted Value per $1,000 in
principal amount of Senior Discount Notes equal to $486.68 (representing the
original price at which the Senior Discount Notes are being offered). The Senior
Discount Notes will accrete (representing the amortization of original issue
discount) on a semiannual bond equivalent basis using a 360-day year comprised
of twelve 30-day months such that the Accreted Value shall be equal to the full
principal amount at maturity of the Senior Discount Notes on April 15, 2005 (the
"Full Accretion Date"). See "Certain Federal Income Tax Considerations." No
interest is payable in cash on the Senior Discount Notes prior to the Full
Accretion Date, other than interest payable as a result of an increase in the
interest as described under the caption "-- Registration Rights." Beginning on
the Full Accretion Date, the Senior Discount Notes will accrue interest at the
rate shown on the front cover of this Memorandum from the Full Accretion Date or
from the most recent Interest Payment Date to which interest has been paid,
payable in cash semiannually in arrears on April 15 and October 15 of each year,
commencing October 15, 2005, to Holders of record on the close of business on
the April 1 or October 1 immediately

                                       87
<PAGE>   15

preceding the Interest Payment Date. See "-- Registration Rights" for a
description of the circumstances under which the interest rate on the Notes may
be increased.

     The Company may, subject to the covenants described below under
"-- Covenants" and applicable law, issue additional Senior Discount Notes under
the Indenture having identical terms and conditions to the Senior Discount Notes
offered hereby. The Senior Discount Notes offered hereby and any additional
Senior Discount Notes subsequently issued would be treated as a single class for
all purposes of the Indenture.

     RANKING

     The Notes will be senior, unsecured (except to the extent described under
"-- Security" below with respect to the Senior Notes) obligations of the Company
and will rank equally in right of payment with all of our existing and future
senior unsecured indebtedness and will be senior in right of payment to all
future subordinated indebtedness of the Company. The Notes (except to the extent
described under "-- Security" below with respect to the Senior Notes) will not
be secured by any assets and will be effectively subordinated to any secured
indebtedness of the Company to the extent of the value of the assets securing
such indebtedness and to all indebtedness and other liabilities (including trade
payables and lease obligations) of our subsidiaries other than any Guarantor. As
of November 30, 1999, on a pro forma as adjusted basis, after giving effect to
the offering and application of proceeds thereof, we and our subsidiaries had
approximately $241.0 million of indebtedness to which holders of the Notes would
have been effectively subordinated. See "Capitalization." The operations of the
Company are conducted through its subsidiaries and, therefore, the Company is
dependent upon cash flow from those entities to meet its obligations. None of
the Company's subsidiaries other than any Guarantor will have any direct
obligation to pay amounts due on the Notes and will not guarantee the Notes. As
of the Closing Date, Cricket Communications Holdings will be the only subsidiary
of the Company which will be a Guarantor. The Guarantee will be a senior,
unsecured obligation of the Guarantor and will rank equally in right of payment
with all existing and future senior, unsecured indebtedness of the Guarantor and
will be subordinate in right of payment to all secured indebtedness of the
Guarantor to the extent of the value of the assets securing such indebtedness.
See "Risk Factors -- Our Ability to Service the Notes Depends on Our Ability to
Get Cash from Our Subsidiaries" and "-- The Notes Will be Effectively
Subordinated to Our Secured Debt." The Company and its subsidiaries will be
permitted to incur additional secured and unsecured indebtedness. See "Risk
Factors -- We Will Have Substantial Indebtedness, and We May Incur More
Indebtedness." See "Covenants -- Limitation on Indebtedness" for a description
of additional indebtedness that may be incurred.

     The Company will grant a security interest to the Trustee for the benefit
of the holders of the Senior Notes in the Pledge Account and all amounts on
deposit therein. The holders of the Senior Notes will have a claim on the
amounts on deposit in the Pledge Account and any investment and reinvestment
thereof that is prior to the claims of other creditors of the Company.

     PAYMENT, DENOMINATIONS

     If a holder has given wire transfer instructions to the Company, the
Company will make all principal, premium, if any, and interest payments on such
Notes in accordance with such instructions. All other principal of, premium, if
any, and interest on the Notes will be payable, and the Notes may be exchanged
or transferred, at the office or agency of the Company maintained for such
purpose in the Borough of Manhattan, the City of New York (which initially will
be the corporate trust office of the Trustee at 61 Broadway, New York, New York
10006); provided that, at the option of the Company, payment of interest may be
made by check mailed to the Holders at their addresses as they appear in the
Security Register.

                                       88
<PAGE>   16

     The Notes will be issued only in fully registered form, without coupons, in
denominations of $1,000 of principal amount at maturity of the Notes and
integral multiples thereof. See "-- Book-Entry; Delivery and Form." No service
charge will be made for any registration of transfer or exchange of Notes, but
the Company may require payment of a sum sufficient to cover any transfer tax or
other similar governmental charge payable in connection therewith.

GUARANTEE

     On the Closing Date, Cricket Communications Holdings will jointly and
severally with any future Guarantors, as primary obligor and not merely as
surety, unconditionally and irrevocably guarantee (the "Guarantee") the due and
punctual payment of the principal of, premium, if any, and interest on the
Notes, on an unsecured basis, in accordance with the terms thereof and of the
Indenture. The Guarantee will be limited so as not to constitute a fraudulent
conveyance under applicable law. See, however, "Risk Factors -- Fraudulent
Conveyance Considerations." After the Closing Date, the Company will cause any
future domestic Restricted Subsidiary (other than any direct or indirect
Subsidiary of Cricket Communications Holdings or any License Subsidiary) and any
Restricted Subsidiary which guarantees certain Indebtedness of the Company to
execute and deliver to the Trustee a Guarantee pursuant to which such Restricted
Subsidiary will jointly and severally with all other Guarantors, as primary
obligor and not merely as surety, unconditionally and irrevocably guarantee the
due and punctual payment of the principal of, premium, if any, and interest on
the Notes, on an unsecured basis, in accordance with the terms thereof and of
the Indenture. See "Covenants -- Limitation on Issuance of Guarantees by
Restricted Subsidiaries" and "-- Future Guarantors." If no Event of Default has
occurred and is continuing, concurrently with any sale or disposition of all of
the Capital Stock of any Guarantor or all or substantially all of the assets of
any Guarantor to any Person that is not an Affiliate of the Company, which sale
or disposition is in compliance with the covenant entitled "Limitation on Asset
Sales" described below, or upon the designation of any Guarantor as an
Unrestricted Subsidiary in compliance with the Indenture, such Guarantor will
automatically and unconditionally be released from all obligations under its
Guarantee.

SECURITY

     The Trustee will establish the Pledge Account on or before the Closing Date
in connection with the issuance of the Senior Notes. On the Closing Date, the
Company will deposit in the Pledge Account, for the benefit of the Holders of
the Senior Notes, an amount from the net proceeds of the Offering of the Senior
Notes sufficient to acquire Pledged Securities in an amount as will be
sufficient upon receipt of scheduled interest and principal payments on such
Pledged Securities to provide payment in full when due of the first seven
scheduled interest payments due on the Senior Notes. The Company expects to use
approximately $78.3 million of the net proceeds from the Offering of the Senior
Notes to acquire the Pledged Securities; however, the actual amount of the net
proceeds used to purchase the Pledged Securities will vary depending on the
interest rates on U.S. government obligations prevailing at the time of the
purchase of the Pledged Securities. The Pledged Securities will be deposited in
the Pledge Account on the Closing Date.

     All amounts deposited in the Pledge Account and the Pledged Securities will
be pledged by the Company to the Trustee for the benefit of the Holders of the
Senior Notes pursuant to the Pledge Agreement. Pursuant to the Pledge Agreement,
immediately prior to an Interest Payment Date for the Senior Notes, the Company
may either deposit with the Trustee from funds otherwise available to the
Company cash sufficient to pay the interest scheduled to be paid on such date or
the Company may direct the Trustee to release from the Pledge Account proceeds
sufficient to pay interest then due on the Senior Notes. In the event the
Company exercises the former option, the Company may direct the

                                       89
<PAGE>   17

Trustee to release a like amount of proceeds from the Pledge Account. The
Pledged Securities and Pledge Account also secure the repayment of the principal
amount and premium on the Senior Notes.

     If an Event of Default shall have occurred and be continuing and the Senior
Notes shall have been accelerated, the Trustee shall apply the funds in the
Pledge Account in the following order of priority: first, to the Trustee for
amounts due to the Trustee under the Indenture; second, to the Holders for
amounts due and unpaid on the Senior Notes for interest, ratably, without
preference or priority of any kind, according to the amounts due and payable on
the Senior Notes for interest; and third, to the Holders for amounts due and
unpaid on the Senior Notes for principal, ratably, without preference or
priority of any kind, according to the amounts due and payable on the Senior
Notes for principal.

     Under the Pledge Agreement, once the Company makes the first six scheduled
interest payments on the Senior Notes, all of the remaining Pledged Securities,
if any, will be released from the Pledge Account and thereafter the Senior Notes
will be unsecured.

OPTIONAL REDEMPTION

     OPTIONAL REDEMPTION OF SENIOR NOTES

     The Senior Notes will be redeemable, at the Company's option, in whole or

     SELECTION

     In the case of any partial redemption, selection of the Senior Notes or
Senior Discount Notes, as the case may be, to be redeemed will be made by the
Trustee in compliance with the requirements of the principal national securities
exchange, if any, on which the Notes are listed or, if the Notes are not listed
on a national securities exchange, on a pro rata basis or by such other method
as the Trustee in its sole discretion shall deem to be fair and appropriate;
provided that no Notes of $1,000 or less in principal amount of the Senior Notes
or Accreted Value of the Senior Discount Notes shall be redeemed in part. If any
Note is to be redeemed in part only, the notice of redemption relating to such
Note shall state the portion of the principal amount thereof to be redeemed. A
new Note in principal amount equal to the unredeemed portion thereof will be
issued in the name of the Holder thereof upon cancellation of the original Note.

     SINKING FUND

     The Notes will not have the benefit of any sinking fund.

REGISTRATION RIGHTS

     The Company will use its best efforts, at its cost, to file and cause to
become effective a registration statement with respect to a registered offer
(the "Exchange Offer") to exchange the Senior Notes and the Senior Discount
Notes, respectively, for senior notes and senior discount notes of the Company,
respectively (the "Exchange Notes"), to be issued under the Indenture with terms
identical to the Senior Notes and Senior Discount Notes, respectively (except
that the Exchange Notes will not contain the interest rate step-up provision
contained herein or bear legends restricting the transfer thereof). Upon such
registration statement being declared effective, the Company shall offer the
Exchange Notes in return for surrender of the Notes. Such offer shall remain
open for not less than 20 business days after the date notice of the Exchange
Offer is mailed to Holders. For each Senior Note or Senior Discount Note
surrendered to the Company under the Exchange Offer, the Holder will receive an
Exchange Note of equal principal amount at maturity. Interest on each Exchange
Note issued in exchange for a Senior Note shall accrue from the last Interest
Payment Date on which interest was paid on the Senior Notes so

                                       91
<PAGE>   19

surrendered or, if no interest has been paid on such Senior Notes, from the
Closing Date. The Accreted Value of each Exchange Note issued in exchange for a
Senior Discount Note shall be identical to, and shall be determined in the same
manner as, the Accreted Value of the Senior Discount Notes so surrendered and
exchanged. Interest on each Exchange Note issued in exchange for a Senior
Discount Note shall be calculated and paid in the same manner as interest on the
Senior Discount Notes so surrendered and exchanged. In the event that applicable
interpretations of the staff of the SEC do not permit the Company to effect the
Exchange Offer, or under certain other circumstances, the Company shall, at its
cost, use its best efforts to cause to become effective a shelf registration
statement (the "Shelf Registration Statement") with respect to resales of the
Notes and to keep such registration statement effective until the earlier of the
expiration of the time period referred to in Rule 144(k) under the Securities
Act and the date upon which all of the Notes covered by the Shelf Registration
Statement have been sold pursuant to the Shelf Registration Statement. The
Company shall, in the event of such a shelf registration, provide to each
registered Holder copies of the prospectus, notify each registered Holder when
the Shelf Registration Statement for the Notes has become effective and take
certain other actions as are required to permit resales of the Notes. A Holder
that sells its Notes pursuant to the Shelf Registration Statement generally will
be required to be named as a selling security holder in the related prospectus
and to deliver a prospectus to purchasers, will be subject to certain of the
civil liability provisions under the Securities Act in connection with such
sales and will be bound by the provisions of the Registration Rights Agreement
that are applicable to such a Holder (including certain indemnification
obligations).

     In the event that the Exchange Offer is not consummated and a Shelf
Registration Statement is not declared effective on or prior to the date that is
180 days after the Closing Date, (i) the interest rate borne by the Senior Notes
shall be increased by .50% per annum over the rate shown on the cover page of
this Memorandum and (ii) interest in addition to the accrual of original issue
discount and in addition to interest otherwise due for periods after the Full
Accretion Date will accrue on the Senior Discount Notes at a rate per annum
equal to .50% of the Accreted Value thereof, in each case until the Exchange
Offer is consummated or a Shelf Registration is declared effective. In the event
of such an increase in the per annum interest rate on the Notes, the Trustee
shall provide notice thereof to the Holders upon receipt of notice from the
Company of such increase.

     The Company will be entitled to close the Exchange Offer 20 business days
after the commencement thereof, provided that it has accepted all Notes
theretofore validly surrendered in accordance with the terms of the Exchange
Offer. Notes not tendered in the Exchange Offer shall bear interest at the rate
set forth on the cover page of this Memorandum and be subject to all of the
terms and conditions specified in the Indenture and to the transfer restrictions
described in "Transfer Restrictions." Holders of Notes who do not participate in
the Exchange Offer may thereafter hold a less liquid security.

     The Company will be required to allow participating broker-dealers and
other persons, if any, with similar prospectus delivery requirements to use the
prospectus contained in the registration statement in connection with the resale
of Exchange Notes for a period of 180 days from the issuance of the Exchange
Notes.

     This summary of certain provisions of the Registration Rights Agreement
does not purport to be complete and is subject to, and is qualified in its
entirety by reference to, all the provisions of the Registration Rights
Agreement, a copy of which is available from the Company upon request.

SUBSIDIARIES

     The Company will not, and will not permit any Restricted Subsidiary to,
create or otherwise cause or suffer to exist or become effective any consensual
encumbrance or restriction of any kind on the ability of any Restricted
Subsidiary to (i) pay dividends or make any other distributions permitted by
applicable law on any Capital Stock of such Restricted Subsidiary owned by the
Company or any other Restricted Subsidiary, (ii) pay any Indebtedness owed to
the Company or any other Restricted Subsidiary, (iii) make loans or advances to
the Company or any other Restricted Subsidiary or (iv) transfer any of its
property or assets to the Company or any other Restricted Subsidiary.

     The foregoing provisions shall not restrict any encumbrances or
restrictions:

          (i) existing on the Closing Date in the Indenture, Pledge Agreement or
     any other agreements in effect on the Closing Date, and any amendments,
     extensions, refinancings, renewals or replacements of such agreements;
     provided that the encumbrances and restrictions in any such amendments,
     extensions, refinancings, renewals or replacements are no less favorable in
     any material respect to the Holders than those encumbrances or restrictions
     that are then in effect and that are being extended, refinanced, renewed or
     replaced;

          (ii) existing under or by reason of applicable law;

          (iii) existing with respect to any Person or the property or assets of
     such Person acquired by the Company or any Restricted Subsidiary, existing
     at the time of such acquisition and not incurred in contemplation thereof,
     which encumbrances or restrictions are not applicable to any Person or the
     property or assets of any Person other than such Person or the property or
     assets of such Person so acquired;

          (iv) in the case of clause (iv) of the first paragraph of this
     "Limitation on Dividend and Other Payment Restrictions Affecting Restricted
     Subsidiaries" covenant, (a) that restrict in a customary manner the
     subletting, assignment or transfer of any property or asset that is a
     lease, license, conveyance or contract or similar property or asset, (b)
     existing by virtue of any transfer of, agreement to transfer, option or
     right with respect to, or Lien on, any property or assets of the Company or
     any Restricted Subsidiary not otherwise prohibited by the Indenture or (c)
     arising or agreed to in the ordinary course of business, not relating to
     any Indebtedness, and that do not, individually or in the aggregate,
     detract from the value of property or assets of the Company or any
     Restricted Subsidiary in any manner material to the Company or any
     Restricted Subsidiary;

                                       112
<PAGE>   40

          (v) with respect to a Restricted Subsidiary and imposed pursuant to an
     agreement that has been entered into for the sale or disposition of all or
     substantially all of the Capital Stock of, or property and assets of, such
     Restricted Subsidiary; or

          (vi) contained in the terms of any Indebtedness of a Restricted
     Subsidiary, or any agreement pursuant to which such Indebtedness was
     issued, if the encumbrance or restriction applies only in the event of a
     payment default or a default with respect to a financial covenant contained
     in such Indebtedness or agreement, if the encumbrance or restriction is not
     materially more disadvantageous to the Holders of the Notes than is
     customary in comparable financings (as determined by the Company) and if
     the Company determines that any such encumbrance or restriction will not
     materially affect the Company's ability to make principal or interest
     payments on the Notes.

     Nothing contained in this "Limitation on Dividend and Other Payment
Restrictions Affecting Restricted Subsidiaries" covenant shall prevent the
Company or any Restricted Subsidiary from (1) creating, incurring, assuming or
suffering to exist any liens otherwise permitted in the "Limitation on Liens"
covenant or (2) restricting the sale or other disposition of property or assets
of the Company or any of its Restricted Subsidiaries that secure Indebtedness of
the Company or any of its Restricted Subsidiaries.

     LIMITATION ON THE ISSUANCE AND SALE OF CAPITAL STOCK OF RESTRICTED
SUBSIDIARIES

     The Company will not sell, and will not permit any Restricted Subsidiary,
directly or indirectly, to issue or sell, any shares of Capital Stock of a
Restricted Subsidiary (including options, warrants or other rights to purchase
shares of such Capital Stock) except (i) to the Company or a Wholly Owned
Restricted Subsidiary; (ii) issuances of director's qualifying shares or sales
to foreign nationals of shares of Capital Stock of foreign Restricted
Subsidiaries, to the extent required by applicable law; (iii) Permitted Cricket
Holdings Shares and Options; (iv) if, immediately after giving effect to such
issuance or sale, such Restricted Subsidiary would no longer constitute a
Restricted Subsidiary, provided any Investment in such Person remaining after
giving effect to such issuance or sale would have been permitted to be made
under the "Limitation on Restricted Payments" covenant, if made on the date of
such issuance or sale, or (iv) issuances and sales of Common Stock of any
Restricted Subsidiary, provided that the Company or such Restricted Subsidiary
applies the Net Cash Proceeds of any such sale in accordance with clause (a) or
(b) of the "Limitation on Asset Sales" covenant described below.

     LIMITATION ON ISSUANCES OF GUARANTEES BY RESTRICTED SUBSIDIARIES

     The Company will not permit any Restricted Subsidiary, directly or
indirectly, to guarantee any Indebtedness of the Company or any Guarantor
("Guaranteed Indebtedness"), unless (i) such Restricted Subsidiary (a) is a
Guarantor or (b) simultaneously executes and delivers a supplemental indenture
to the Indenture providing for a Guarantee of payment of the Notes by such
Restricted Subsidiary and (ii) such Restricted Subsidiary waives, and will not
in any manner whatsoever claim or take the benefit or advantage of, any rights
of reimbursement, indemnity or subrogation or any other rights against the
Company or any other Restricted Subsidiary as a result of any payment by such
Restricted Subsidiary under its Guarantee; provided that this paragraph shall
not be applicable to (a) any guarantee by a Restricted Subsidiary existing on
the Closing Date or in respect of Indebtedness Incurred pursuant to clause (i)
or (vii) of the second paragraph of the "Limitation on Indebtedness" covenant or
(b) any guarantee of any Restricted Subsidiary that existed at the time such
Person became a Restricted Subsidiary and was not Incurred in connection with,
or in contemplation of, such Person becoming a Restricted Subsidiary. If the
Guaranteed Indebtedness is (1) pari passu with the Notes or any Guaranty, then
the guarantee of such Guaranteed Indebtedness shall be pari passu with, or
subordinated to, the Guarantee or (2) subordinated to the Notes or any Guaranty,
then the guarantee of

                                       113
<PAGE>   41

such Guaranteed Indebtedness shall be subordinated to the Guarantee at least to
the extent that the Guaranteed Indebtedness is subordinated to the Notes.

     Notwithstanding the foregoing, any Guarantee executed by a Restricted
Subsidiary pursuant to this provision shall provide by its terms that it shall
be automatically and unconditionally released and discharged upon (i) any sale,
exchange or transfer, to any Person not an Affiliate of the Company, of all of
the Company's and each Restricted Subsidiary's Capital Stock in, or all or
substantially all of the assets of, such Restricted Subsidiary (which sale,
exchange or transfer is not prohibited by the Indenture) or (ii) the release or
discharge of the guarantee which resulted in the creation of such Guarantee,
except a discharge or release by or as a result of payment under such guarantee.

     LIMITATION ON TRANSACTIONS WITH STOCKHOLDERS AND AFFILIATES

     The Company will not, and will not permit any Restricted Subsidiary to,
directly or indirectly, enter into, renew or extend any transaction (including,
without limitation, the purchase, sale, lease or exchange of property or assets,
or the rendering of any service) with any holder (or any Affiliate of such
holder) of 5% or more of any class of Capital Stock of the Company or with any
Affiliate of the Company or any Restricted Subsidiary, except upon fair and
reasonable terms no less favorable to the Company or such Restricted Subsidiary
than could be obtained, at the time of such transaction or, if such transaction
is pursuant to a written agreement, at the time of the execution of the
agreement providing therefor, in a comparable arm's-length transaction with a
Person that is not such a holder or an Affiliate.

     The foregoing limitation does not limit, and shall not apply to (i)
transactions (a) approved by a majority of the Disinterested Directors or (b)
for which the Company or a Restricted Subsidiary delivers to the Trustee a
written opinion of a nationally recognized investment banking firm stating that
the transaction is fair to the Company or such Restricted Subsidiary from a
financial point of view; (ii) any transaction solely between the Company and any
of its Wholly Owned Restricted Subsidiaries or solely between Wholly Owned
Restricted Subsidiaries; (iii) the payment of reasonable and customary regular
fees to directors of the Company who are not employees of the Company; (iv) any
payments or other transactions pursuant to any tax-sharing agreement between the
Company and any other Person with which the Company files a consolidated tax
return or with which the Company is part of a consolidated group for tax
purposes; or (v) any Restricted Payments not prohibited by the "Limitation on
Restricted Payments" covenant. Notwithstanding the foregoing, any transaction
covered by the first paragraph of this "Limitation on Transactions with
Stockholders and Affiliates" covenant and not covered by clauses (ii) through
(v) of this paragraph, (1) must be approved in the manner provided for in clause
(i)(a) above and a certified Board Resolution to such effect delivered to the
Trustee, if the aggregate amount of such transaction exceeds $2 million, and (2)
must be determined fair in the manner provided for in clause (i)(b) above, if
the aggregate amount of such transaction exceeds $10 million.

     LIMITATION ON LIENS

     The Company will not, and will not permit any Restricted Subsidiary to,
create, incur, assume or suffer to exist any Lien on any of its assets or
properties of any character, or any shares of Capital Stock or Indebtedness of
any Restricted Subsidiary, without making effective provision for all of the
Notes and the Guarantees and all other amounts due under the Indenture to be
directly secured equally and ratably with (or, if the obligation or liability to
be secured by such Lien is subordinated in right of payment to the Notes, prior
to) the obligation or liability secured by such Lien.

     The foregoing limitation does not apply to (i) Liens existing on the
Closing Date; (ii) Liens granted after the Closing Date on any assets or Capital
Stock of the Company or its Restricted Subsidiaries created in favor of the
Holders; (iii) Liens with respect to the assets of a Restricted Subsidiary
granted by such Restricted Subsidiary to the Company or a Wholly Owned
Restricted Subsidiary to secure

                                       114
<PAGE>   42

Indebtedness owing to the Company or such other Restricted Subsidiary; (iv)
Liens securing Indebtedness which is permitted to be Incurred under clause (i)
of the "Limitation on Indebtedness" covenant; (v) Liens securing Indebtedness
which is Incurred to refinance secured Indebtedness which is permitted to be
Incurred under clause (iii) of the second paragraph of the "Limitation on
Indebtedness" covenant; provided that such Liens do not extend to or cover any
property or assets of the Company or any Restricted Subsidiary other than the
property or assets securing the Indebtedness being refinanced; (vi) Liens on the
Capital Stock of, or any property or assets of, a Restricted Subsidiary securing
Indebtedness of such Restricted Subsidiary (or obligations in respect thereof)
or Indebtedness of any Restricted Subsidiary guaranteed by such Restricted
Subsidiary permitted under the "Limitation on Indebtedness" covenant; or (vii)
Permitted Liens.

     Notwithstanding the foregoing, the Company will not create, incur or suffer
to exist any Lien on the capital stock of Cricket Communications Holdings.

     LIMITATION ON SALE-LEASEBACK TRANSACTIONS

     The Company will not, and will not permit any Restricted Subsidiary to,
enter into any sale-leaseback transaction involving any of its assets or
properties whether now owned or hereafter acquired, whereby the Company or a
Restricted Subsidiary sells or transfers such assets or properties and then or
thereafter leases such assets or properties or any part thereof or any other
assets or properties which the Company or such Restricted Subsidiary, as the
case may be, intends to use for substantially the same purpose or purposes as
the assets or properties sold or transferred.

     The foregoing restriction does not apply to any sale-leaseback transaction
if (i) the lease is for a period, including renewal rights, of not in excess of
three years; (ii) the lease secures or relates to industrial revenue or
pollution control bonds; (iii) the transaction is solely between the Company and
any Wholly Owned Restricted Subsidiary or solely between Wholly Owned Restricted
Subsidiaries; or (iv) the Company or such Restricted Subsidiary, within twelve
months after the sale or transfer of any assets or properties is completed,
applies an amount not less than the net proceeds received from such sale in
accordance with clause (a) or (b) or of the second paragraph of the "Limitation
on Asset Sales" covenant described below.

     FUTURE SUBSIDIARY GUARANTORS

     The Company will cause each domestic Restricted Subsidiary other than any
direct or indirect Subsidiary of Cricket Communications Holdings or any License
Subsidiary to execute and deliver a Guarantee pursuant to which each such
Subsidiary will, jointly and severally, Guarantee irrevocably and
unconditionally all principal, premium, if any, and interest on the Notes on an
unsecured basis.

     LIMITATION ON ASSET SALES

     The Company will not, and will not permit any Restricted Subsidiary to,
consummate any Asset Sale, unless (i) the consideration received by the Company
or such Restricted Subsidiary is at least equal to the fair market value of the
assets sold or disposed of as evidenced by a Board Resolution filed with the
Trustee, and (ii) at least 75% of the consideration received consists of cash or
Temporary Cash Investments, provided that the amount of any (a) liabilities (as
shown on the Company's or such Restricted Subsidiary's most recent balance
sheet) of the Company or any Restricted Subsidiary (other than contingent
liabilities and liabilities that are by their terms subordinated to the Notes or
any Guarantee) that are assumed by the transferee of any such assets pursuant to
an agreement that irrevocably releases the Company or such Restricted Subsidiary
from further liability shall be deemed to be cash for purposes of this
provision.

                                       115
<PAGE>   43

     In the event and to the extent that the Net Cash Proceeds received by the
Company or any of its Restricted Subsidiaries from one or more Asset Sales
occurring on or after the Closing Date in any period of 12 consecutive months
exceed 10% of Adjusted Consolidated Net Tangible Assets (determined as of the
date closest to the commencement of such 12-month period for which a
consolidated balance sheet of the Company and its Subsidiaries has been filed
with the Trustee pursuant to the "Commission Reports and Reports to Holders"
covenant), then the Company shall or shall cause the relevant Restricted
Subsidiary to (i) within 12 months after the date Net Cash Proceeds so received
exceed 10% of Adjusted Consolidated Net Tangible Assets (a) apply an amount
equal to such excess Net Cash Proceeds to permanently repay unsubordinated
Indebtedness of the Company or any Guarantor or Indebtedness of any other
Restricted Subsidiary, in each case owing to a Person other than the Company or
any of its Restricted Subsidiaries or (b) invest an equal amount, or the amount
not so applied pursuant to clause (a) (or enter into a definitive agreement
committing to so invest within 12 months after the date of such agreement), in
property or assets (other than current assets) of a nature or type or that are
used in a business (or in a company having property and assets of a nature or
type, or engaged in a business) similar or related to the nature or type of the
property and assets of, or the business of, the Company and its Restricted
Subsidiaries existing on the date of such investment and (ii) apply (no later
than the end of the 12-month period referred to in clause (i)) such excess Net
Cash Proceeds (to the extent not applied pursuant to clause (i)) as provided in
the following paragraph of this "Limitation on Asset Sales" covenant. The amount
of such excess Net Cash Proceeds required to be applied (or to be committed to
be applied) during such twelve-month period as set forth in clause (i) of the
preceding sentence and not applied as so required by the end of such period
shall constitute "Excess Proceeds."

     If, as of the first day of any calendar month, the aggregate amount of
Excess Proceeds not theretofore subject to an Offer to Purchase pursuant to this
"Limitation on Asset Sales" covenant totals at least $10,000,000, the Company
must commence, not later than the fifteenth Business Day of such month, and
consummate an Offer to Purchase from the Holders on a pro rata basis an
aggregate principal amount of Notes equal to the Excess Proceeds on such date,
at a purchase price equal to 100% of the principal amount of the Senior Notes or
Accreted Value of the Senior Discount Notes, plus, in each case, accrued
interest (if any) to the Payment Date.

     ADDITIONAL HOLDING COMPANIES

     The Company shall not create any subsidiary which directly or indirectly
owns (i) Capital Stock of Cricket Communications Holdings or (ii) Capital Stock
of Cricket Communications, Inc., other than Cricket Communications Holdings.

REPURCHASE OF NOTES UPON A CHANGE OF CONTROL

     The Company must commence, within 30 days of the occurrence of a Change of
Control, and consummate an Offer to Purchase for all Notes then outstanding, at
a purchase price equal to 101% of the principal amount of the Senior Notes or
Accreted Value of the Senior Discount Notes, plus accrued interest (if any) to
the Payment Date.

     There can be no assurance that the Company will have sufficient funds
available at the time of any Change of Control to make any debt payment
(including repurchases of Notes) required by the foregoing covenant (as well as
may be contained in other securities of the Company which might be outstanding
at the time). The above covenant requiring the Company to repurchase the Notes
will, unless consents are obtained, require the Company to repay all
indebtedness then outstanding which by its terms would prohibit such Note
repurchase, either prior to or concurrently with such Note repurchase.

     The Company will furnish to each of the Holders of Notes within the time
period specified in the SEC's rules and regulations (i) all quarterly and annual
financial information that would be required to be contained in a filing with
the Commission on forms 10-Q and form 10-K as if the Company were required to

Commission will not accept such a filing) and make such information available to
security analysts and prospective investors upon request for so long as any

     clause (a), (b) or (c) above) and such default or breach continues for a
     period of 30 consecutive days after written notice by the Trustee or the

     the Holders of 25% or more of the aggregate principal amount at maturity of
     the Senior Discount Notes, as the case may be;

     created, (1) an event of default that has caused the holder thereof to
     declare such Indebtedness to be due and payable prior to its Stated
     Maturity and such Indebtedness has not been discharged in full or such
     acceleration has not been rescinded or annulled within 30 days of such
     acceleration and/or (2) the failure to make a principal payment at the

     payment of money in excess of $5 million in the aggregate for all such
     final judgments or orders against all such Persons (treating any
     deductibles, self-insurance or retention as not so covered) shall be
     rendered against the Company or any Restricted Subsidiary and shall not be
     paid or discharged, and there shall be any period of 60 consecutive days
     following entry of the final judgment or order that causes the aggregate
     amount for all such final judgments or orders outstanding and not paid or
     discharged against all such Persons to exceed $5 million during which a
     stay of enforcement of such final judgment or order, by reason of a pending
     appeal or otherwise, shall not be in effect;

          (g) a court having jurisdiction in the premises enters a decree or
     order for (1) relief in respect of the Company or any Restricted Subsidiary
     in an involuntary case under any applicable bankruptcy, insolvency or other
     similar law now or hereafter in effect, (2) appointment of a receiver,
     liquidator, assignee, custodian, trustee, sequestrator or similar official

          (h) the Company or any Restricted Subsidiary (1) commences a voluntary
     case under any applicable bankruptcy, insolvency or other similar law now
     or hereafter in effect, or consents to the entry of an order for relief in
     an involuntary case under any such law, (2) consents to the appointment of

     terms;

          (j) except upon the release of any Guarantee in accordance with the
     Indenture, (1) any Guarantee ceases to be in full force and effect or is
     declared null and void or (2) any Guarantor denies that it has any further
     liability under the Guarantee or gives notice to that effect; or

          (k) there shall have occurred any loss, suspension, revocation or
     non-renewal of the wireless licenses of the Company and its Restricted
     Subsidiaries covering 50% or more of the total potential customers covered
     by all of the wireless licenses of the Company and its Restricted
     Subsidiaries.

     If an Event of Default (other than an Event of Default specified in clause
(g) or (h) above that occurs with respect to the Company) occurs and is
continuing under the Indenture, the Trustee or the Holders of at least 25% in
aggregate principal amount of the Senior Notes or the Holders of at least 25% in
aggregate principal amount at maturity of the Senior Discount Notes, as the case
may be, then outstanding, by written notice to the Company (and to the Trustee
if such notice is given by the Holders), may, and the Trustee at the request of
such Holders shall, declare the principal of all outstanding Senior Notes or the
Accreted Value of all outstanding Senior Discount Notes, as the case may be,
together with premium, if any, and all accrued and unpaid interest thereon to be
immediately due and payable. Upon a declaration of acceleration, such principal
of, premium, if any, and accrued interest shall be immediately due and payable.
In the event of a declaration of acceleration because an Event of Default set
forth in clause (e) above has occurred and is continuing, such declaration of
acceleration shall be automatically rescinded and annulled if the event of
default triggering such Event of Default pursuant to clause (e) shall be
remedied or cured by the Company or the relevant Subsidiary or waived by the
holders of the relevant Indebtedness within 60 days after the declaration of
acceleration with respect thereto. If an Event of Default specified in clause
(g) or (h) above occurs with respect to

                                       118
<PAGE>   46

the Company, the principal of, premium, if any, and accrued interest on the
Notes then outstanding shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder. At any time after declaration of acceleration, but before a judgment or
decree for the payment of the money due has been obtained by the Trustee, the
Holders of at least a majority in principal amount of the outstanding Senior
Notes or the Holders of at least a majority in aggregate principal amount at
maturity of the outstanding Senior Discount Notes by written notice to the
Company and to the Trustee, may waive all past defaults and rescind and annul a
declaration of acceleration and its consequences if (i) all existing Events of
Default, other than the nonpayment of the principal of, premium, if any, and
interest on the Notes that have become due solely by such declaration of
acceleration, have been cured or waived and (ii) the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction. For
information as to the waiver of defaults, see "-- Modification and Waiver."

     The Holders of at least a majority in aggregate principal amount of the
outstanding Senior Notes or Holders of at least a majority in aggregate
principal amount at maturity of the outstanding Senior Discount Notes, as the
case may be, may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or exercising any trust or power
conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the Trustee
in personal liability, or that the Trustee determines in good faith may be
unduly prejudicial to the rights of Holders of Notes not joining in the giving
of such direction and may take any other action it deems proper that is not
inconsistent with any such direction received from Holders of Notes. A Holder
may not pursue any remedy with respect to the Indenture or the Notes unless: (i)
the Holder gives the Trustee written notice of a continuing Event of Default;
(ii) the Holders of at least 25% in aggregate principal amount of outstanding
Senior Notes or the Holders of at least a majority in aggregate principal amount
at maturity of the outstanding Senior Discount Notes, as the case may be, make a
written request to the Trustee to pursue the remedy; (iii) such Holder or
Holders offer the Trustee indemnity satisfactory to the Trustee against any
costs, liability or expense; (iv) the Trustee does not comply with the request
within 60 days after receipt of the request and the offer of indemnity; and (v)
during such 60-day period, the Holders of a majority in aggregate principal
amount of the outstanding Notes do not give the Trustee a direction that is
inconsistent with the request. However, such limitations do not apply to the
right of any Holder of a Note to receive payment of the principal of, premium,
if any, or interest on, such Note or to bring suit for the enforcement of any
such payment, on or after the due date expressed in the Notes, which right shall
not be impaired or affected without the consent of the Holder.

     The Indenture will require certain officers of the Company to certify, on
or before a date not more than 90 days after the end of each fiscal year, that a
review has been conducted of the activities of the Company and its Restricted
Subsidiaries and the Company's and its Restricted Subsidiaries' performance
under the Indenture and that the Company has fulfilled all obligations
thereunder, or, if there has been a default in the fulfillment of any such
obligation, specifying each such default and the nature and status thereof. The

organized and validly existing under the laws of the United States of America or
any jurisdiction thereof and shall expressly assume, by a supplemental
indenture, executed and delivered to the Trustee, all of the obligations of the
Company on all of the Notes and under the Indenture; (ii) immediately after
giving effect to such transaction on a pro forma basis, no Default or Event of
Default shall have occurred and be continuing; (iii) immediately after giving
effect to such transaction on a pro forma basis, the Company or any Person
becoming the successor obligor of the Notes shall have a Consolidated Net Worth
equal to or greater than the Consolidated Net Worth of the Company immediately
prior to such transaction, provided that this clause (iii) shall only apply to a
sale of less than all of the assets of the Company; (iv) immediately after
giving effect to such transaction on a pro forma basis the Company, or any
Person becoming the successor obligor of the Notes, as the case may be, could
Incur at least $1.00 of Indebtedness under the first paragraph of the
"Limitation on Indebtedness" covenant described above; provided that this clause
(iv) shall not apply to a consolidation or merger or sale of all (but not less
than all) of the assets of the Company if all Liens and Indebtedness of the
Company or any Person becoming the successor obligor on the Notes, as the case
may be, and its Restricted Subsidiaries outstanding immediately after such
transaction would, if Incurred at such time, have been permitted to be Incurred

transaction, shall be deemed to have been Incurred) for all purposes of the
Indenture; (v) if the Company is not the surviving or continuing Person, each
Guarantor shall have delivered a written instrument in form satisfactory to the
Trustee confirming its Guarantee; and (vi) the Company delivers to the Trustee

stating that such consolidation, merger or transfer and such supplemental
indenture, if any, complies with this provision and that all conditions
precedent provided for herein relating to such transaction have been complied
with; provided, however, that clauses (iii) and (iv) above do not apply if, in
the good faith determination of the Board of Directors of the Company, whose
determination shall be evidenced by a Board Resolution, the principal purpose of
such transaction is to change the state of incorporation of the Company; and
provided further that any such transaction shall not have as one of its purposes
the evasion of the foregoing limitations.

     The Company will not permit any Guarantor (other than any Guarantor whose
Guarantee is to be released in accordance with the terms of the Guarantee and
the Indenture in connection with any transaction complying with the provisions
described in the "Limitation on Assets Sales" covenant described above) to, in a
single transaction or a series of related transactions, (i) consolidate with or
merge with or into any other Person (other than a Guarantor which is a Wholly
Owned Restricted Subsidiary) or (ii) directly or indirectly, transfer, sell,
lease or otherwise dispose of all or substantially all of its assets, unless:
(a) the Guarantor shall be the surviving or continuing Person, or the Person (if
other than the Guarantor) formed by such consolidation or into which the
Guarantor is merged or that acquired or leased such property and assets of the

any jurisdiction thereof and shall expressly assume, by a supplemental
indenture, executed and delivered to the Trustee, all of the Guarantor's
obligations under the Indenture; (b) immediately after giving effect to such
transaction on a pro forma basis, no Default or Event of Default shall have
occurred and be continuing; (c) immediately after giving effect to such
transaction on a pro forma basis, the Company or any Person becoming a successor
obligor on the Notes, as the case may be, could Incur at least $1.00 of

Indebtedness" covenant described above; and (d) the Company shall have delivered

to demonstrate compliance with clause (c)) and an Opinion of Counsel, in each
case stating that such consolidation, merger or transfer and such supplemental
indenture , if any, complies with this provision and that all conditions
precedent provided for herein relating to such transaction have been complied

DEFEASANCE

     DEFEASANCE AND DISCHARGE

     The Indenture will provide that the Company and the Guarantors will be
deemed to have paid and will be discharged from any and all obligations in
respect of the Senior Notes and/or the Senior Discount Notes on the 123rd day
after the deposit referred to below, and the provisions of the Indenture will no
longer be in effect with respect to the Notes (except for, among other matters,
certain obligations to register the transfer or exchange of the Notes, to
replace stolen, lost or mutilated Notes, to maintain paying agencies and to hold
monies for payment in trust) if, among other things, (i) the Company has
deposited with the Trustee, in trust, money and/or U.S. Government Obligations
that through the payment of interest and principal in respect thereof in
accordance with their terms will provide money in an amount sufficient to pay
the principal of, premium, if any, and accrued interest on the Notes on the
Stated Maturity of such payments in accordance with the terms of the Indenture
and the Notes, (ii) the Company has delivered to the Trustee (a) either (1) an
Opinion of Counsel to the effect that Holders will not recognize income, gain or
loss for federal income tax purposes as a result of the Company's exercise of
its option under this "Defeasance" provision and will be subject to federal
income tax on the same amount and in the same manner and at the same times as
would have been the case if such deposit, defeasance and discharge had not
occurred, which Opinion of Counsel must be based upon (and accompanied by a copy
of) a ruling of the Internal Revenue Service to the same effect unless there has
been a change in applicable federal income tax law after the Closing Date such
that a ruling is no longer required or (2) a ruling directed to the Trustee
received from the Internal Revenue Service to the same effect as the
aforementioned Opinion of Counsel and (b) an Opinion of Counsel to the effect
that the creation of the defeasance trust does not violate the Investment
Company Act of 1940 and after the passage of 123 days following the deposit
(except with respect to any trust funds for the account of any Holder who may be
deemed an "insider" for purposes of the United States Bankruptcy Code, after one
year following the deposit); the trust funds will not be subject to the effect
of Section 547 of the United States Bankruptcy Code or Section 15 of the New
York Debtor and Creditor Law, (iii) immediately after giving effect to such
deposit on a pro forma basis, no Default or Event of Default shall have occurred
and be continuing on the date of such deposit or during the period ending on the
123rd day after the date of such deposit, and such deposit shall not result in a
breach or violation of, or constitute a default under, any other agreement or
instrument to which the Company or any of its Subsidiaries is a party or by
which the Company or any of its Subsidiaries is bound, and (iv) if at such time
the Notes are listed on a national securities exchange, the Company has
delivered to the Trustee an Opinion of Counsel to the effect that the Notes will
not be delisted as a result of such deposit, defeasance and discharge.

     DEFEASANCE OF CERTAIN COVENANTS AND CERTAIN EVENTS OF DEFAULT

     The Indenture further will provide that the provisions of the Indenture
will no longer be in effect with respect to clauses (iii) and (iv) under
"Consolidation, Merger and Sale of Assets" and all the covenants described
herein under "Covenants," clauses (c) and (d) under "Events of Default" with
respect to such clauses (iii) and (iv) under "Consolidation, Merger and Sale of
Assets" and such covenants and clauses (e) and (f) under "Events of Default"
shall be deemed not to be Events of Default, upon, among other things, the
deposit with the Trustee, in trust, of money and/or U.S. Government Obligations
that through the payment of interest and principal in respect thereof in
accordance with their terms will provide money in an amount sufficient to pay
the principal of, premium, if any, and accrued interest on the Notes on the
Stated Maturity of such payments in accordance with the terms of the Indenture
and the Notes, the satisfaction of the provisions described in clauses (ii)(b),
(iii) and (iv) of the preceding paragraph and the delivery by the Company to the
Trustee of an Opinion of Counsel to the effect that, among other things, the
Holders will not recognize income, gain or loss for federal income tax purposes
as a result of such deposit and defeasance of certain covenants and Events of

                                       121
<PAGE>   49

Default and will be subject to federal income tax on the same amount and in the
same manner and at the same times as would have been the case if such deposit
and defeasance had not occurred.

     DEFEASANCE AND CERTAIN OTHER EVENTS OF DEFAULT

     In the event the Company exercises its option to omit compliance with
certain covenants and provisions of the Indenture with respect to the Notes as
described in the immediately preceding paragraphs and the Notes are declared due
and payable because of the occurrence of an Event of Default that remains
applicable, the amount of money and/or U.S. Government Obligations on deposit
with the Trustee will be sufficient to pay amounts due on the Notes at the time
of their Stated Maturity but may not be sufficient to pay amounts due on the
Notes at the time of the acceleration resulting from such Event of Default.
However, the Company will remain liable for such payments.

MODIFICATION AND WAIVER

     Modifications and amendments of the Indenture may be made by the Company
and the Trustee with the consent of the Holders of not less than a majority in
aggregate principal amount of the outstanding Senior Notes or the Holders of not
less than a majority in aggregate principal amount at maturity of the
outstanding Senior Discount Notes, as the case may be; provided, however, that
no such modification or amendment may, without the consent of each Holder
affected thereby, (i) change the Stated Maturity of the principal of, or any
installment of interest on, any Note, (ii) reduce the principal of, or premium,
if any, or interest on, any Note, (iii) change the place or currency of payment
of principal of, or premium, if any, or interest on, any Note, (iv) impair the
right to institute suit for the enforcement of any payment on or after the
Stated Maturity (or, in the case of a redemption, on or after the Redemption
Date) of any Note, (v) reduce the above-stated percentage of outstanding Notes
the consent of whose Holders is necessary to modify or amend the Indenture, (vi)
waive a default in the payment of principal of, premium, if any, or interest on
the Notes or (vii) reduce the percentage or aggregate principal amount of
outstanding Notes the consent of whose Holders is necessary for waiver of
compliance with certain provisions of the Indenture or for waiver of certain
defaults.

NO PERSONAL LIABILITY OF INCORPORATORS, STOCKHOLDERS, OFFICERS, DIRECTORS OR
EMPLOYEES

     The Indenture provides that no recourse for the payment of the principal
of, premium, if any, or interest on any of the Notes or for any claim based
thereon or otherwise in respect thereof, and no recourse under or upon any
obligation, covenant or agreement of the Company in the Pledge Agreement, the
Indenture, or in any of the Notes or because of the creation of any Indebtedness
represented thereby, shall be had against any incorporator, stockholder,
officer, director, employee or controlling person of the Company or of any
successor Person thereof. Each Holder, by accepting the Notes, waives and
releases all such liability.

CONCERNING THE TRUSTEE

     The Indenture provides that, except during the continuance of a Default,
the Trustee will not be liable, except for the performance of such duties as are
specifically set forth in such Indenture. If an Event of Default has occurred
and is continuing, the Trustee will use the same degree of care and skill in its
exercise as a prudent person would exercise under the circumstances in the
conduct of such person's own affairs.

     The Indenture and provisions of the Trust Indenture Act of 1939, as
amended, incorporated by reference therein contain limitations on the rights of
the Trustee, should it become a creditor of the Company, to obtain payment of
claims in certain cases or to realize on certain property received by it in
respect of any such claims, as security or otherwise. The Trustee is permitted
to engage in other transactions; provided, however, that if it acquires any
conflicting interest, it must eliminate such conflict or resign.
