been agreed upon in the Definitive Agreements; and (iii) Cricket shall provide
Ericsson with a copy of its current business plan and financial information, so
as to enable Ericsson to evaluate and make an informed business decision with
regard to whether it wishes to offer the proposed vendor financing. The Cricket
Notice shall provide reasonable specificity as to the requested information.
Cricket further agrees to reasonably cooperate with Ericsson by providing any
non-confidential information reasonably requested by Vendor for purposes of
verifying the information contained in Cricket's Notice, and, if requested by
Ericsson, will allow the audit procedure set forth in the Master Agreement to be

<PAGE>   4

set forth in the Definitive Agreements as provide in Section 3.4, and Ericsson
disapproves any such proposed new terms; or (iv) if Cricket's business plan or
financial information as provided by Cricket do not meet Ericsson's
satisfaction. Ericsson shall use commercial reasonable efforts to: (a) satisfy
the milestones; and (b) have its Board of Directors approve the financing. If
any of the items (i) through (iv) above within this Section occur, Ericsson may
terminate this Memorandum of Agreement and the Definitive Agreements by
providing written notice to Cricket (the "Ericsson Second Notice"). If Ericsson
exercises its termination option, the parties shall be relieved of all further
rights and obligations under this Memorandum of Agreement and the Definitive
Agreements; and Ericsson shall have no liability in connection with such
termination. If Ericsson fails to give the Ericsson Second Notice on or before
the date thirty (30) calendar days after receipt of the Cricket Notice, Cricket
shall give Ericsson notice of its failure to give the Ericsson Second Notice
and, if Ericsson has not given the Ericsson Second Notice within five (5)
business days after notice that the Ericsson Second Notice is late, then
Ericsson shall have been deemed to have terminated its obligations hereunder,
and the Memorandum of Agreement and the Definitive Agreements shall terminate
without further liability to either party.


3.     PURCHASE OF EQUIPMENT. Unless the Memorandum of Agreement is terminated
pursuant to Section 2.3 above and subject to satisfaction of the conditions set

software) from Ericsson Products and Services for mobile and fixed wireless
communications Systems based on CDMA digital wireless communications technology
in markets in the United States, pursuant to the terms and conditions set forth
below. The minimum commitment of Cricket to purchase and Ericsson to sell shall
be $330,000,000 of total value. The purchase obligations of Cricket are subject
to: (i) the existence of Available Markets (as defined below) at any time after
Ericsson is prepared to deliver the first System for commercial operations; (ii)
Ericsson being prepared to deliver the first System for


                                       4
<PAGE>   5
commercial operation within twenty-four (24) months from the Effective Date of
this Memorandum of Agreement and (iii) Ericsson complying with each of the other
terms set forth in this Section 3. If Ericsson fails to meet the milestones
and/or other requirements set forth in this Section 3, Cricket shall have the
option, as its sole and exclusive remedy to terminate this Memorandum of
Agreement and the Definitive Agreements without any further liability to either
party. The terms and conditions of such purchases shall be as follows:

         3.1. TECHNICAL SPECIFICATIONS. The Systems to be purchased by Cricket
and sold by Ericsson shall comply with any specifications agreed to by the
parties in the Definitive Agreements and those additional specifications as
published by Ericsson from time to time thereafter. In addition, in all cases,
the Systems shall meet the "Minimum Equipment Specifications" as set forth on
Exhibit A to this Memorandum of Agreement.

         3.2. DEVELOPMENT PROCESS AND MILESTONES. To demonstrate that the
Systems to be sold by Ericsson will meet the Minimum Equipment Specifications
set forth on Exhibit A, the parties agree that Ericsson shall follow the
"Procedures and Milestones for System Development and Monitoring Program" set

         3.3. DEFINITIVE AGREEMENTS. Within thirty (30) days after the Effective
Date, Ericsson and Cricket shall diligently and in good faith negotiate and
execute a System Equipment Purchase Agreement that shall be on the terms and
conditions set forth herein and on those additional terms contained in the Form
of Agreement. In the event of any inconsistency or conflict between the
Memorandum of Agreement and the Form of Agreement, the parties shall revise the
Form of Agreement to be consistent with the terms and concepts contained in this
Memorandum of Agreement. If the parties have not reached agreement on the
Definitive Agreements within thirty (30) days, the parties shall continue
efforts to negotiate the Definitive Agreements, and this Memorandum of Agreement
will continue in full force and effect. The parties shall complete negotiation
of those areas noted as open issues on the Form of Agreement (including but not
limited

                                       5
<PAGE>   6


to missing or incomplete exhibits) and those other areas which require
modification to reflect unique aspects of the Ericsson System and procedures
provided that such modifications are not inconsistent with non-operational
issues provide that no such modification shall require Cricket to accept changes
which materially and adversely impact the cost of acquiring, installing,
maintaining or operating the System, unless such change was expressly
contemplated with regard to an unopen item. Other provisions of the Form of
Agreement shall not be subject to negotiation and the negotiation of open issues
(including prices) will not be inconsistent with terms established herein or in
the Form of Agreement which are not designated as "open."


        3.4. VENDOR FINANCING. Ericsson shall provide to Cricket, vendor
financing in an amount not less than [*] of the purchase price of the System(s)
and Equipment acquired by Cricket from Ericsson on the terms and conditions set
forth in the term sheet attached hereto as Exhibit D, or such more favorable
terms as may be available to Cricket on the date of the Cricket Notice for
shipments on the date that Ericsson intends to first ship Products to Cricket,
if Cricket provides the Cricket Notice as provided above, the terms and
conditions of such financing shall be no less favorable in rates and terms and
conditions to Cricket (and its affiliates) than those terms and conditions
offered by Cricket's other Primary Vendor for comparable financing on the date
Cricket provides Cricket's Notice. "Primary Vendor" means Cricket's or its
affiliates then current primary (i.e., in terms of dollar cost of Equipment then
on order and which has been ordered within the previous three (3) months) vendor
for supplying the Systems. Within sixty (60) days after the Effective Date, the
parties agree to diligently and in good faith negotiate and execute: (i)
definitive form of loan documents, which are substantially similar to those loan
documents of Cricket's other Primary Vendor; and (ii) an intercreditor
agreement. Cricket shall diligently and in good faith attempt to obtain the
Primary Vendor's written approval to the form of an intercreditor agreement to
be used between

<PAGE>   7

Ericsson and Primary Vendor. The parties agree to execute documents and
amendments as necessary to accomplish the foregoing.

        3.5. PRICING. The price for the Systems to be purchased by Cricket
pursuant to this Memorandum of Agreement shall not be higher than the pricing
for comparable Systems available to Cricket from the Primary Vendor as of the
date of the Cricket Notice for Systems and Products to be delivered on the date
of first shipment of Ericsson Products to Cricket as established by Cricket
pursuant to the Cricket Notice provided as required by Section 2.2
above. The parties agree to use commercially reasonable efforts to cause the
determination of Ericsson's infrastructure prices versus the infrastructure
prices of the Primary Vendor, to be based on an "apples-to-apples" comparison
(taking into consideration not only the pricing of products and services, the
costs to obtain, install, maintain and operate the system, and the terms and
conditions of any other material consideration proposed to be given or received
by any competing bidder, including the financing terms and conditions and each
of the Competitive Factors (as that term is defined in the Master Agreement).

        3.6. VENDOR PREFERENCE. Provided that: Ericsson (i) has given a
timely Ericsson First Notice; (ii) has satisfied the conditions of Section 3
above; and (iii) has not given an Ericsson Second Notice, Cricket shall purchase
from Ericsson a System for the next Available Market (the "Test Market")
deployed by Cricket or its affiliates after the earlier of: (a) the date
twenty-four (24) months after the Effective Date; or (b) twelve (12) months
after the gives the Ericsson First Notice. "Available Market" means any market
where Cricket or any of its affiliates have acquired a license to build and
operate a System, which is not yet deployed and whether such market currently
exists as of the Effective Date or is acquired thereafter; provided however, it
excludes any Contiguous Markets. A "Contiguous Market" means a market owned by
Cricket or any of its affiliates that is geographically close or proximate to
an existing market where Cricket or any of its affiliates have deployed a
System, and where operating synergies would be

                                       7

<PAGE>   8
gained or capital expenditures would be avoided by deploying additional Systems
identical to those in the existing market (i.e., Salt Lake City, UT would be
considered a Contiguous Market to Provo, UT, since operating efficiencies would
exist). The System deployed in the Test Market will be subject to a "soak"
period, whereby it will be operated for six (6) months after the Substantial
Completion date (the "Test Period") in order to determine whether it is
operating in accordance with the Definitive Agreements and the Specifications.
Provided the System in the Test Market has operated in accordance with the
Specifications and Definitive Agreements during the Test Period, thereafter
Cricket shall purchase from Ericsson any additional Products and Services for
deployment in its remaining Available Markets in accordance with the following:
(i) if as of the expiration of the Test Period the projected cost (as reasonably
set forth in Cricket's business plan) to deploy Products and Services in all of
the remaining Available Markets is equal to or greater than $330,000,000 (less
the price of the Products and Services previously deployed in the Test Market),
then Cricket agrees to purchase a minimum of $330,000,000 (less the price of the
Products and Services previously deployed in the Test Market) of Products and
Services for deployment in such remaining Available Markets; or (ii) if as of
the expiration of the Test Period the projected cost (as reasonably set forth in
Cricket's business plan) to deploy Products and Services in all of the remaining
Available Markets is less than $330,000,000 (less the price of the Products and
Services previously deployed in the Test Market), then Cricket shall purchase
from Ericsson all of its Products and Services requirements for the Remaining
Markets until such time as Cricket has purchased from Ericsson Products and
Services with an aggregate total cost of $330,000,000 (less the price of the
Products and Services previously deployed in the Test Market). Cricket agrees
that it will deploy its Products and Services in good faith in a commercially
reasonable manner and will not arrange the deployment schedule so as to deploy
Products and Services in the Contiguous Markets where the purpose is to delay
the deployment of Ericsson's Products and Services in the Test Market.

Cricket as set forth in this Memorandum of Agreement, Ericsson agrees that upon
the earlier of: (i) execution of the Definitive Agreements; or (ii) thirty (30)
days after the Effective Date of this Memorandum of Agreement; (y) the
provisions of Section 2.4.4 of the Master Agreement be and hereby are terminated
and such Section shall be of no further force or effect; and (z) for all future
purchases by Leap and/or Cricket and/or their affiliates under Section 2 of the
Master Agreement, Ericsson's price must be not higher than the Lowest Competing
Infrastructure Bid (defined in the Master Agreement) or there shall be no
obligation to award any procurement to Ericsson (i.e., the parties hereby
eliminate the provisions in Section 2 that require Leap and/or Cricket and/or
their affiliates in certain circumstances to purchase Infrastructure Equipment
(defined in the Master Agreement) from Ericsson if the Ericsson Infrastructure
Prices (defined in the Master Agreement) are within 110% of the Lowest Competing
Infrastructure Bid). Without affecting the immediate enforceability of the
forgoing, the parties agree to negotiate and execute a more formal amendment to
the Master Agreement that will memorialize the foregoing amendments and which
shall be executed concurrently with the Definitive Agreements. Except as set
forth above, the term and provisions of the Master Agreement shall continue in
full force and effect. Notwithstanding the foregoing, pricing and purchase terms
for purchases made under this Memorandum of Agreement and the Definitive
Agreements are not affected by the Master Agreement.

Owner's inability to acquire sufficient rights to a location which could
constitute a Site in a timely or economic manner; provided that all such
alterations requested by Owner shall be considered by Owner and addressed
pursuant to the Change Order provisions described in Section 11 below. Vendor
shall offer to Owner Site Acquisition services as defined on Exhibit E and
according to the pricing set forth on Exhibit B-7. When making changes to the RF
engineering plan, the Vendor shall take into account the Site Acquisition
already completed by the Owner. Upon Site Acquisition Substantial Completion,

errors, inconsistencies or omissions so discovered or discovered by any of its

commissions as may be necessary for construction and operation of a PCS System.
Vendor reserves the right to self-insure its obligations hereunder.

            2.7 Further Assurances. The Vendor shall execute and deliver all
reasonable further instruments and documents, and will, in good faith, consider
all reasonable requests for further action, including but not limited to
assisting the Owner in filing notices of completion with the appropriate state
and local Governmental Entity, that may be necessary or that the Owner may
reasonably request in order to enable the Owner or the Vendor to complete
performance of the Work or to effectuate the purposes or intent of this
Contract. All such requests shall be addressed pursuant to the Change Order
procedures described below in Section 11.

            2.8 Liens and Other Encumbrances. (a) The Vendor covenants and
agrees, subject to Vendor's receipt from Owner of full payment in respect
thereof, to:

                        (i) protect and keep free all Systems, Expansion and/or
      any and all interests and estates therein acquired from the Vendor, and
      all improvements and materials now or hereafter placed thereon under the
      terms of this Contract, from any and all claims, liens, charges or
      encumbrances of the nature of mechanics, labor or materialmen liens or
      otherwise arising out of or in connection with performance by any
      Subcontractor, including services or furnishing of any materials
      hereunder, and to promptly have any such lien released by bond or
      otherwise; and

                        (ii) give notice of this subsection to each
      Subcontractor before such Subcontractor furnishes any labor or materials
      for any System.

            (b) If any laborers', materialmen's, mechanics', or other similar
lien or claim thereof is filed by any Subcontractor, the Vendor shall cause such
lien to be satisfied or otherwise discharged, or shall file a bond in form and
substance satisfactory to the Owner in lieu thereof within ten (10) Business
Days of the Vendor's receipt of notice of such filing. If any such lien is filed
or otherwise imposed, and the Vendor does not cause such lien to be released and
discharged forthwith, or file a bond in lieu thereof, then, without limiting the
Owner's other available remedies, the Owner has the right, but not the
obligation, to pay all sums necessary to obtain such release and discharge or
otherwise cause the lien to be removed or bonded to the Owner's satisfaction
from funds retained from any payment then due or thereafter to become due to the
Vendor.

            (c) The Owner reserves the right to post or place within any System
notices of non-responsibility or to do any other act required by Applicable Law,
to exempt the Owner from any liability to third parties by reason of any work or
improvements to be performed or furnished hereunder; provided that failure by
the Owner to do so shall not release or discharge the Vendor from any of its
obligations hereunder.

            2.9 Duty To Inform Itself Fully; Waiver of Defense. (a) Each party
shall be deemed to have notice of and to have fully examined and approved the
Specifications, the Exhibits and all other documents referred to herein, and all
drawings, specifications, schedules, terms and conditions of this Contract,
regulations and other information in relation to this Contract and/or any
amendments, modifications or supplements thereto at


                                       15

            SECTION 3. PURCHASE ORDERS AND SCHEDULES

            3.1 Purchase Orders. The Owner and any Operating Affiliate may
deliver Purchase Orders to the Vendor at any time and from time to time during
the Contract Term. Such Purchase Orders shall be sent to the Vendor either by
certified mail, electronic transmission or another mutually acceptable manner to
the address specified in Exhibit L of this Contract. All Purchase Orders shall
be governed by the terms and conditions of this Contract, unless otherwise
agreed by the parties in writing. Each Purchase Order shall specify, in
reasonable detail, the Products, Services or other items of Work to be provided
by the Vendor.

            3.2 Delivery under the Contract. The Vendor shall complete the Work
specified in each Purchase Order in accordance with the terms and conditions of
this Contract.

            3.3 Order Acceptance. All Purchase Orders submitted by Owner shall
be deemed to incorporate and be subject to the terms and conditions of this
Contract unless otherwise agreed in writing. All Purchase Orders, including
electronic orders, shall contain the information necessary for Vendor to fulfill
the order. All schedules and requested dates are subject to Vendor's
concurrence, provided that if orders are made within the agreed to lead times
specified in Exhibit L, Vendor shall not withhold its concurrence to the
requested dates. No provision or data on any Purchase Order or contained in any
documents attached to or referenced in any Purchase Order, or any subordinate
document (such as shipping releases), which is inconsistent with the terms of
this Contract shall be binding, except data necessary for Vendor to fill the
order. All such other data and provisions are hereby rejected. Electronic orders
shall be binding on Owner notwithstanding the absence of a signature, provided
that the parties have implemented a mutually acceptable electronic order process
and such orders deemed to be binding have been issued by Owner and accepted by
Vendor in accordance with the process agreed upon by the parties. Order
acceptance provisions, together with delivery schedules and intervals and
forecast requirements are set forth in Exhibit L.

      While it is Vendor's objective to provide Owner with an acknowledgment of
each Purchase Order received, Owner shall advise Vendor to the extent that Owner
becomes


                                       16
<PAGE>   31
aware of any missing or late notifications to ensure that the Purchase Order has
not been lost.

      Changes made by Owner to an accepted Purchase Order shall be treated as a
separate order unless the parties expressly agree otherwise. If any such change
affects Vendor's ability to meet its obligations under the original Purchase
Order, any price, shipment date, or completion date quoted by Vendor with
respect to such original order is subject to change and shall be addressed
pursuant to the Change Order provisions below in Section 11.

            3.4 Forecasts. Owner shall provide to Vendor regular forecasts of
Owner's annual Product and Services needs. If the quantities ordered are more
than [*] greater than forecast quantities, Vendor shall be permitted a
reasonable extension of time to fulfill such orders and achieve the Milestones
required of Vendor hereunder.

            3.5 Deployment Plans and Milestones. The deployment plans and
intervals, together with the key milestones, order lead times, in respect of
each System, are set forth in Exhibit L.

            3.6 Inventory Control and Bar-coding. Vendor shall, at no additional
charge, pack and mark shipping containers in accordance with its standard
practices for domestic shipments. Where in order to meet Owner's requests,
Vendor packs and/or is required to mark shipping cartons in accordance with
Owner's specifications, Vendor shall invoice Owner additional charges for such
packing and/or marking. Vendor shall: (i) enclose a packing memorandum with each
shipment and, if the shipment contains more than one package, identify the
package containing the memorandum; and (ii) mark Products as applicable for
identification in accordance with Vendor's marking specifications (for example,
model/serial number and month, year of manufacture).

            SECTION 4. SUBCONTRACTORS

            4.1 Subcontractors. The Vendor may subcontract any portion of its
obligations under this Contract, but no such subcontract shall relieve Vendor
from primary responsibility and liability for the performance of Vendor's
covenants and obligations under this Contract. Regardless of whether or not the
Vendor obtains approval from the Owner or a Subcontractor or whether the Vendor
uses a Subcontractor recommended by the Owner, use by the Vendor of a
Subcontractor shall not, under any circumstances: (i) give rise to any claim by
the Vendor against the Owner if such Subcontractor breaches its subcontract or
contract with the Vendor; (ii) give rise to any claim by such Subcontractor
against the Owner; (iii) create any contractual obligation by the Owner to the
Subcontractor; (iv) give rise to a waiver by the Owner of its rights to reject
any Defects or Deficiencies or Defective Work; or (v) in any way release the
Vendor from being solely responsible to the Owner for the Work to be performed
under this Contract.

[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

<PAGE>   32
            4.2 Vendor's Liability. The Vendor is responsible for all of its
obligations under this Contract, including the Work, regardless of whether a
subcontract or supply agreement is made or whether the Vendor relies upon any
Subcontractor to any extent. The Vendor's use of Subcontractors for any of the
Work shall in no way increase the Vendor's rights or diminish the Vendor's
liabilities to the Owner with respect to this Contract, and in all events,
except as otherwise expressly provided for herein, the Vendor's rights and
liabilities hereunder with respect to the Owner shall be as though the Vendor
had itself performed such Work. The Vendor shall be liable for any delays caused
by any Subcontractor as if such delays were caused by the Vendor.

            4.3 No Effect of Inconsistent Terms in Subcontracts. The terms of
this Contract shall in all events be binding upon the Vendor regardless of and
without regard to the existence of any inconsistent terms in any agreement
between the Vendor and any Subcontractor whether or not and without regard to
the fact that the Owner may have directly and/or indirectly had notice of any
such inconsistent term.

            4.4 Assignability of Subcontracts to Owner. Vendor shall use
reasonable efforts to have each agreement between the Vendor and a Subcontractor
contain a provision stating that, in the event that the Vendor is terminated for
cause, convenience, abandonment of this Contract or otherwise then: (i) each
Subcontractor shall continue its portion of the Work as may be requested by the
Owner; and (ii) such agreement permits assignment thereof without penalty to the
Owner and, in order to create security interests, to third parties designated by
Owner, in either case at the option of the Owner and for the same price and
under the same terms and conditions as originally specified in such
Subcontractor's agreement with the Vendor.

            4.5 Removal of Subcontractor or Subcontractor's Personnel. The Owner
has the right at any time to request removal of a Subcontractor and/or any of a
Subcontractor's personnel from Work on the System upon reasonable grounds and
reasonable prior notice to Vendor. Such request (a "Request for Removal") shall
be in writing and shall specify the Owner's reasoning therefor. The Vendor
promptly shall issue a written response to any such Request for Removal,
specifying the reasoning for its disagreement or agreement, as the case may be,
with the reasoning contained in the Request for Removal. If the parties fail to
agree, this matter shall be handled in accordance with the dispute resolution
procedures in Section 23. The exercise of such right by the Owner shall have no
effect on the provisions of subsections 4.1 and 4.2.

            4.6 Subcontractor Insurance. The Vendor shall require its
Subcontractors to obtain, maintain and keep in force, during the time they are
engaged in providing Products and Services hereunder, insurance coverage of the
types and levels customary in the industry (provided that the maintenance of any
such Subcontractor insurance shall not relieve the Vendor of its other
obligations pursuant to this Contract). The Vendor shall, upon the Owner's
request, furnish the Owner with evidence of such insurance in form and substance
reasonably satisfactory to the Owner.

<PAGE>   33
            4.7 Review and Approval not Relief of Vendor Liability. No
inspection, review or approval by the Owner permitted under this Contract of any
portion of the Work shall relieve the Vendor of any duties, liabilities or
obligations under this Contract, but nothing contained in this subsection shall
be deemed a bar of any waiver given by the Owner to the Vendor pursuant to and
in accordance with the terms of this Contract.

            4.8 Vendor Warranties. Except as otherwise expressly provided in
Section 18, the warranties of the Vendor pursuant to Section 18 shall be deemed
to apply to all Work performed by any Subcontractor as though the Vendor had
itself performed such Work and to all Products supplied by any third-party
vendor or other subcontractor as though the Vendor itself had supplied such
Products. Except as otherwise specifically provided in Section 18, the parties
agree that such warranties shall not be enforceable merely on a "pass-through"
basis but that Owner may, but shall not be obligated to, enforce such warranties
of any Subcontractor to the extent that the Owner determines that the Vendor is
not paying and/or performing its warranties; provided that any such election by
the Owner shall not relieve the Vendor from any obligations or liability with
respect to any such warranty.

            4.9 Payment of Subcontractors. The Vendor shall make all payments it
is contractually required to make to all Subcontractors (except in the case of
legitimate disputes between the Vendor and any such Subcontractor arising out of
the agreement between the Vendor and such Subcontractor) in accordance with the
respective agreements between the Vendor and its Subcontractors such that no
Subcontractor shall be in a position to enforce any liens and/or other rights
against the Owner, the System, any Products or any part thereof.

            4.10 Copies. Subject to any confidentiality obligations insisted
upon by third party providers, including Subcontractors, Vendor will use its
good faith, reasonable efforts to provide Owner with any and all relevant
agreements, understandings, subcontracts and other documents pertaining to the
provision of Products or Services by a Subcontractor which Owner may reasonably
require in order for it to be provided with the information necessary to
exercise any of its rights under this Contract.

            4.11 Benefit of Subcontracts. In addition to anything else provided
for in this Contract, the Owner shall be entitled to the following benefits and
rights of the Vendor under its contracts with any applicable third-party vendors
or other Subcontractors: all rights to conduct in-house tests, to receive notice
of upgrades and enhancements and to purchase spare parts; provided however, that
the Vendor shall maintain sole responsibility for all obligations and other
duties under all such contracts.

Contract, provided, however, that the Owner shall not be liable for and shall
not pay or reimburse Vendor for any Taxes on or measured by the income or

      a delay in reaching Substantial Completion solely attributable to the
      failure or lack of performance of Owner to satisfy its obligations and
      commitments in a timely manner, such amount shall be invoiced on the fifth
      (5th) Business Day following Substantial Completion; and

respect of the System for which such Services are rendered; provided that in the
event that a Certificate of Substantial Completion is not issued within five (5)
Business Days after the Guaranteed Substantial Completion Date because of a
delay in reaching Substantial Completion solely attributable to the failure or

            (c) Optional Software Features and Spares. The purchase price for
the initial Optional Software Features and Spares shall be invoiced after the

which such initial Optional Software Features and Spares are furnished; provided
that in the event that a Certificate of Substantial Completion is not issued
within five (5) Business Bays after the Guaranteed Substantial Completion Date
because of a delay in reaching Substantial Completion attributable solely to the
failure or lack of performance of Owner to satisfy its obligations and
commitments in a timely manner, such amount shall be invoiced on the fifth (5th)

      installation Services pursuant to an Expansion shall be invoiced upon
      delivery of such Products.

            (e) Payment of Invoices. Owner shall pay the invoiced amounts, less
any disputed amounts, within ten (10) days from the date of transmission of
Vendor's invoice. Delinquent payments are subject to a late payment charge after

of this Contract.

            5.6 In Revenue Payments. At any time during a period of delay the
Owner may, in its sole discretion, decide to place a System which is subject to
such delay into In Revenue Service. Such placement into In Revenue Service shall
constitute Substantial Completion only for purposes of the payment obligations
above, but shall not in any way relieve the Vendor of any of its obligations
under this Contract, including without limitation achieving a Guaranteed
Substantial Completion Date nor shall such In Revenue Service trigger the
commencement of the Initial Period.

            5.7 Currency and Place of Payment. Payments under this Contract

safeguard to avoid damage to existing facilities, and if repairs or new
construction are required in order to replace facilities damaged by the Vendor
due to its carelessness, negligence or willful misconduct, such repairs or new
construction shall be at the Vendor's sole cost and expense. Vendor understands
that many of the Sites may be co-located with other RF transmission facilities
and Vendor shall take all necessary precautions and safety measures to ensure
the safety of all of Vendor's and Subcontractors' personnel at such Sites. The
Owner shall use its reasonable best efforts to ensure that no other third
parties employed or engaged by the Owner hinder or delay the Vendor in the
performance of its installation obligations hereunder.

            Vendor represents and warrants that all Products furnished hereunder
shall comply, to the extent required, with the requirements of Part 24 of the

pertaining to personal communications services in effect upon delivery of such
Product. In addition, Vendor represents and warrants that a Product furnished
hereunder shall comply, to the extent required, with the requirements of Subpart
J of Part 15 of the FCC Rules in effect upon delivery of such Product, including
those sections concerning the labeling of such Product and the suppression of
radio frequency and electromagnetic radiation to specified levels. Vendor makes
no undertaking with respect to harmful interference caused by (i) unauthorized
installation, repair, modification or change or Products not furnished by
Vendor; (ii) Products being subject to misuse, neglect, accident or abuse by
other than Vendor; (iii) Products being used in a manner not in accordance with
operating instructions or in a suitable installation environment or operations
of other equipment in the frequency ranges reserved for Owner within the
applicable licensed area. Vendor assumes no


                                       23
<PAGE>   38
responsibility under this clause for items not specified or supplied by Vendor.
The foregoing warranties are collectively referred to as the "Compliance
Warranty".

            Vendor shall, when appropriate, have reasonable access to Owner's
premises during normal business hours and at such other times as may be agreed
upon by the parties in order to enable Vendor to perform its obligations under
this Contract. Vendor shall coordinate such access with Owner's designated
representative prior to visiting such premises. Vendor agrees to instruct its
employees to comply with all site rules while on Owner's premises. The employees
and agents of Vendor shall, while on the Owner's premises, comply with all site
rules and guidelines including but not limited to where required by government
regulations, submission of satisfactory clearance from U.S. Department of

require waivers or releases of any personal rights from representatives of the
other in connection with visits to its premises, and no such releases or waivers
shall be pleaded by either party in any action or proceeding.

            For purposes of this Section, all references to "Owner's premises"
and other similar references shall be deemed to refer to any location where a
Site is to be located, which may include land or buildings owned or leased by
Owner. To the extent that Owner does not own the premises, Vendor's obligations
to adhere to site rules and guidelines shall include, without limitation, those
rules and guidelines required by the owner, landlord or property manager having

            10.2 Costs and Expenses. The costs and expenses of complying with
all acceptance procedures set forth above shall be borne by the Vendor, provided
that Owner remains responsible for completing those items identified as Owner's
responsibility in the Exhibits.

            SECTION 11. CHANGE ORDERS AND SCHEDULING

            11.1 Change Orders. The Owner has the right to request expansions,
other revisions and/or modifications to any Purchase Order or to the Work
("Changes"), including but not limited to the Specifications, the manner of
performance of the Work or the timing of the completion of the Work. All Changes
shall be subject to the prior written consent of the Vendor. All Changes shall
be documented in a written order ("Change Order") which shall be executed by the
Owner and the Vendor and shall contain any adjustments to pricing, Milestone or
other aspect of the Work as mutually agreed by the parties. The Vendor shall
promptly notify the Owner of any such requested Changes which may materially
affect the operation and/or maintenance of any System or any part thereof. In
the event that the parties cannot agree on a Change Order within fifteen (15)
days of submission of a Change Order by the Owner to the Vendor, the matter
shall then be referred to dispute resolution pursuant to Section 23. Nothing
contained in this subsection is intended to limit the Vendor's right, from time
to time, to make suggestions for modifications to the Work or the
Specifications, provided that in any such event the Owner, in its sole and
absolute discretion pursuant to the terms of this Contract may refuse to make
any such modification or otherwise agree to issue a Change Order incorporating
any such Vendor suggestion.

            11.2 Cancellation. Owner may at any time to cancel, in whole or in
part, any Purchase Order or Change Order upon advance written notice to the
Vendor. In the

    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       27
<PAGE>   42
event of such cancellation, the Owner shall pay to the Vendor cancellation
charges in accordance with the Exhibits.

            SECTION 12. DISCONTINUED PRODUCTS AND CONTINUING PRODUCT SUPPORT

            12.1 Notice of Discontinuation. For a period of [*] for the
AXE switch and [*] for all other Products furnished hereunder after the
Effective Date, but in no event less than [*] after the date of shipment,
the Vendor agrees to provide the Owner, or its affiliates as the case may be,
not less than one (1) year notice before the Vendor discontinues a Product
("Discontinued Products") furnished under this Contract. With respect to
Products manufactured by a third party vendor, the notice period may vary. Where
the Vendor offers a product for sale that is equivalent in Form, Fit and
Function in accordance with and pursuant to the Specifications, the notification
period may vary but in no event shall be less than sixty (60) days. In the event
of the foregoing, the Vendor shall continue to furnish Products fully compatible
with the relevant System Elements within the System at such time during the
appropriate [*] and [*] periods referenced above; provided that nothing
herein shall bar the Vendor from discontinuing individual items of Products as
provided in and pursuant to this subsection. In the event that Vendor
discontinues a Product, Vendor will meet with Owner and use reasonable, good
faith efforts to develop a mutually acceptable transition plan that takes into
account the Owner's existing investment in the item scheduled for
discontinuance.

            In addition to repairs provided for under any applicable Warranty,
Vendor shall offer repair Services and repair parts in accordance with Vendor's
repair and repair parts practices and terms and conditions then in effect, for
Vendor-manufactured Equipment furnished pursuant to this Contract. Such repair
Services and repair parts shall be available while Vendor is manufacturing or
stocking such Products or repair parts, but in no event less than [*] for
the AXE switch and [*] for all other Products after such Product's discontinued
availability effective date. Vendor may use either the same or functionally
equivalent products or parts which are new, remanufactured, reconditioned or
refurbished in the furnishing of repairs or replacements under this Contract.

            If during the agreed-to support period following the issuance of
notice of discontinuance, Vendor fails to provide repair parts and or repair
Services and a functionally equivalent replacement has not been designated,
Vendor shall so advise Owner, to allow Owner to plan appropriately, and if
Vendor is unable to identify another source of supply for such repair parts or
services, Vendor shall, in addition to any other right or remedy available to
Owner at law or in equity, provide Owner, at no additional charge to Owner, upon
request, with non-exclusive licenses for Product manufacturing to the extent
Vendor can grant such licenses, so that Owner will have sufficient information,
ability and rights to have such Discontinued Products manufactured, or obtain
such repair Service or repair parts from other sources. Such license shall
include appropriate non-disclosure and confidentiality covenants.

[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

<PAGE>   43
            12.2 Discontinuation During Warranty Period. If Vendor discontinues
the availability of a Product during that Product's Warranty Period and Owner is
required to purchase a replacement Product to replace the Discontinued Product
in order to maintain the same functionality of the Discontinued Product in a
System, Vendor agrees to grant Owner an additional [*] discount to be applied
against the net price of all Products required to be purchased by Owner as
replacements for such Discontinued Product, which additional discount shall be
applied after the determination of the lowest price available to Owner pursuant
to this Contract.

            SECTION 13. SOFTWARE; CONFIDENTIAL INFORMATION

            13.1 RTU License. Upon delivery of the Software, but subject to
payment of the license fees specified in Exhibit B-5, the Owner is hereby
granted a personal, non-exclusive, fully paid-up, multi-site (capability to move
Software from site to site on prior notice to Vendor) right to use license for
the Software ("RTU License"), to operate the specific Equipment, processor or
product line for which the licenses to use the Software are initially granted,
or temporarily on any comparable replacement if any such Equipment, processor or
product line becomes inoperative. Owner shall use such Software only for its own
internal business operation. The RTU License grants Owner no right to, and Owner
will not, sublicense such Software or modify, decompile, or disassemble Software
furnished as object code to generate corresponding source code provided in each
of the Systems. Except as provided below, no license is granted to Owner to use
the Software outside of the United States.

            In the event that Owner wishes to use the Software on associated
equipment outside of the United States or to transfer Software to an affiliate
or third party transferee located outside the United States, Vendor shall not
unreasonably withhold its consent to such use or transfer, provided that Vendor
or the transferee, as the case may be, enters into an appropriate license
agreement with an affiliate of Vendor carrying on business in the territory in
which the Software is to be located, on terms substantially similar to the RTU
License terms set forth herein, provided, however, that Owner acknowledges and
agrees that support and maintenance obligations set forth herein are only
applicable for Software resident on Equipment located within the United States.
Support and maintenance Services offered by Vendor's affiliates differs in
various different territories, and will be subject to the local practices
maintained in such territory.

            13.2 Owner's Obligations. The Owner agrees that the Software,
whether or not modified, and all copies thereof made by Owner, shall be treated
as proprietary to the Vendor, its Subcontractors or its suppliers, as
appropriate and the Owner shall:

            (a) Utilize the Software solely in conjunction with a System;
provided that the Vendor acknowledges that the Software shall be integrated
across interfaces with systems, equipment and software provided by other
suppliers and customers;

[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       29
<PAGE>   44
            (b) Ensure that all copies of the Software shall, upon any
reproduction by the Owner authorized by the Vendor and whether or not in the
same form or format as such Software, contain the same proprietary,
confidentiality and copyright notices or legends which appear on the Software
provided pursuant hereto; and

            (c) Hold secret and not disclose the Software to any person, except
to (i) such of its employees, contractors, agents or affiliates that are
involved in the operation or management of a System and need to have access
thereto to fulfill their duties in such capacity, or (ii) other Persons who need
to use such Software to permit integration of a System with systems and software
of other suppliers and customers; provided that such persons agree, or are
otherwise obligated, to hold secret and not disclose the Software to the same
extent as if they were subject to this Contract, and provided further that if
any such Person is a competitor of Vendor involved in the manufacture of
communications equipment, software or related services, Vendor must approve such
use on a case-by-case basis on commercially reasonable terms and such use shall
be subject to an appropriate non-disclosure agreement.

            (d) When and if the Owner determines that it no longer needs the
Software or if the Owner's license is canceled or terminated pursuant to the
terms of this Contract, return all copies of such Software to the Vendor or
follow reasonable written disposition instructions provided by the Vendor. If
the Vendor authorizes disposition by erasure or destruction, the Owner shall
remove from the medium on which Software resides all electronic evidence of the
Software, both original and derived, in such manner that prevents subsequent
recovery of such original or derived Software.

            (e) Owner shall not copy Software embodied in firmware and unless
otherwise specifically provided in this Contract, Owner is not granted any right
to modify Software furnished by Vendor under this Contract.

            13.3 Backwards Compatibility. The Vendor represents and warrants
(the "Software Backwards Compatibility Warranty") that each Software Maintenance
Release, Software Upgrade and Software Enhancement will be Backwards Compatible.
[***] Notwithstanding the foregoing, the Software Backwards Compatibility
Warranty does not apply to Products developed AXE in accordance with standards
not yet finalized as of the date hereof.

            13.4 Transfer and Relocation. (a) In the event the Owner or any
successor to the Owner's title in the Products: (i) elects to transfer a Product
to a third party, and where such Product shall remain in place and used for
substantially the same purpose as used by the Owner and where such third party
resides in the United States and is not a direct competitor of the Vendor
involved in the manufacture of communications equipment, software or related
services; or (ii) elects to transfer Products to an affiliate, the Owner may

    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       30
<PAGE>   45
transfer its RTU License for the Software furnished under this Contract for use
with such Product, without the payment of any additional Software right-to-use
fees by the transferee provided that Annual Maintenance Fees shall continue to
be calculated on the same basis. For example, if the RTU License for the
Software contains usage or per subscriber limits, or the processor to be used by
transferee requires additional memory or hard disk space additional payments or
purchases may be required. The following conditions shall apply to transfers and
relocations pursuant to this subsection 13.4:

            (A)   The right to use such Software may be transferred only
                  together with the Products with which the Owner has a right to
                  use such Software, and such right to use the Software shall
                  continue to be limited to use with such Products;

            (B)   Before any such Software is transferred, the Owner shall
                  notify the Vendor of such transfer and the transferee shall
                  have agreed in writing (a copy of which shall be provided to
                  the Vendor) to keep the Software in confidence and to
                  corresponding conditions respecting possession and use of
                  Software as those imposed on the Owner in this Contract; and

            (C)   The transferee shall have the same right to Software warranty
                  and Software maintenance for such Software as the transferor,
                  provided the transferee continues to pay the fees, including
                  recurring fees, if any, associated with such Software warranty
                  or maintenance pursuant to this Contract.

            (b) Except as otherwise provided in this Contract, the Owner or any
successor to the Owner's title in the Products shall have no right to transfer
Software furnished by the Vendor under this Contract without the consent of the
Vendor, which consent shall not be unreasonably withheld. If the Owner or such
successor elects to transfer a Product purchased under this Contract for which
it does not under this Contract have the right to transfer related Software, the
Vendor agrees that upon written request of the transferee of such Product, or of
the Owner or such successor, the Vendor shall not without reasonable cause fail
to grant to the transferee a license to use such Software with the Products,
whether to be located within the United States or elsewhere, upon payment of a
relicensing fee to the Vendor on commercially reasonable terms acceptable to
Vendor.

            13.5 Termination and Survival. The rights and obligations of the
Owner under the RTU License shall survive the termination of this Contract,
regardless of the cause of termination provided Owner has met its material
obligations hereunder and has rendered all payments in accordance with this
Contract. In the event that Owner persistently and materially breaches its
confidentiality obligations hereunder with respect to the Software
notwithstanding the fact that Vendor will have provided Owner with prior written
notice describing the alleged material breaches and will have given Owner a
reasonable time, and in no event less than thirty (30) days, to cure any such
breaches, Vendor may terminate Owner's RTU License. In the event that Owner
fails to pay the Annual Release


                                       31
<PAGE>   46
Maintenance Fees (other than with respect to any periods for which no payment
for Annual Release Maintenance Fees are due pursuant to this Contract), Vendor
may terminate Owner's right to use the Software to which such fees apply. In no
event other than as set forth in this subsection 13.5 may Vendor terminate
Owner's right to use the Software. Notwithstanding any other provision of this
Contract, if there is a dispute, pending final resolution of such dispute, all
of Owner's rights under this Contract shall continue in full force and effect,
and Vendor will not terminate the RTU License, and so long as Owner continues to
pay Vendor applicable Annual Maintenance Release Fees, Vendor will not
terminate, suspend, interrupt or delay maintenance and support of the Software.

            13.6 Access to Source Codes. The Vendor represents and warrants that
as of the date hereof, Vendor has not established a Source Code escrow for any
of its existing customers. In the event that Vendor establishes a Source Code
escrow in the future which applies to any of the Software furnished to Owner
hereunder, Vendor shall add Owner as a beneficiary of such Source Code escrow,
and Owner shall be entitled to receive a copy of the escrowed Source Code in the
event of the occurrence of any of the events set out below. In addition to the
foregoing, the Vendor shall immediately deliver and hereby grants the Owner a
right to access the Source Code and to modify the Software (the "RTM License")
for the maintenance, enhancement and support of those Products purchased from
the Vendor and owned or operated by the Owner under the following circumstances,
provided that any such released Source Code shall be subject to the
confidentiality provisions set forth in this Contract:

                        (i) if the Vendor becomes insolvent, makes a general
      assignment for the benefit of creditors, files a voluntary petition in
      bankruptcy or an involuntary petition in bankruptcy is filed against the
      Vendor which is not dismissed within sixty (60) days, or suffers or
      permits the appointment of a receiver for its business, or its assets
      become subject to any proceeding under a bankruptcy or insolvency law,
      domestic or foreign, or has liquidated its business, or the Vendor, or a
      business unit of the Vendor that is responsible for maintenance of the
      Software, ceases doing business without providing for a successor, and the
      Owner has reasonable cause to believe that any such event shall cause the
      Vendor to be unable to meet its Warranty service or support requirements
      hereunder; or

                        (ii) if the Vendor ceases to maintain or support a
      previously supported version of the Software and Owner cannot obtain, with
      Vendor's assistance (for example, by providing a third party with Source
      Code or by any other appropriate method) the same support services the
      Vendor is required to provide under this Contract from another entity
      (either working with or independently from Vendor) at a price that is
      equal to or less than the prices for such support as provided herein, or
      there is a persistent and material failure by Vendor to provide the
      Warranty service or support it is required to provide pursuant to the
      terms of this Contract.

            13.7 Ownership of Intellectual Property. The Vendor shall own all
forms of intellectual property rights (including, but not limited to, patent,
trade secret, copyright and

mask rights) pertaining to the Software, and shall have the right to file for or
otherwise secure and protect such rights. The foregoing notwithstanding, the
parties understand and agree that from time to time the Owner may devise,
develop or otherwise create ideas or other concepts for services or new products
which are patentable or otherwise capable of receiving protection from
duplication. In such event, the Owner shall have the right to apply for a patent
in accordance with applicable law, provided, however, that notwithstanding this
subsection, the Vendor does not hereby relinquish or release any of its
intellectual property rights.

            SECTION 14. SOFTWARE AND EQUIPMENT CHANGES

            14.1 Software.

            14.1.1 Software Upgrades, Software Maintenance Releases, Software
Enhancements and Combined Releases. During the Contract Term, upon payment of
the Annual Release Maintenance Fees, calculated pursuant to Exhibit B-5, Owner
shall receive all base Software releases and all Software Maintenance Releases,
Software Upgrades, Software Enhancements and Software Combined Releases
applicable to Software for Products for which the Owner has obtained a RTU
License at such times as they become generally available to the Vendor's
customers. Owner shall also be entitled to receive Optional Software Features
upon payment of the appropriate fees determined in accordance with Exhibit B-5.
Owner may elect to purchase such features on a per feature basis, or purchase
annual buy-out rights on a per market basis, permitting Owner to select those
features it wishes to deploy in the relevant market.

            14.1.2 Notice. The Vendor shall give the Owner, or cause the Owner
to be given not less than ninety (90) days prior written notice of the
introduction of any Software Enhancement release or any Software Combined
Release or any optional Software release. In addition, in each February and
August of each year during the term of this Contract, the Vendor shall provide,
or cause to be provided, to the Owner a forecast of future Software Enhancement
releases, Software Upgrades, or Software Combined Releases or any optional
Software release, as the case may be, then currently being developed by or on
behalf of the Vendor.

            14.1.3 Installation, Testing and Maintenance. The installation and
testing of the Software by the Vendor and the acceptance thereof by the Owner
shall be performed in accordance with the criteria set forth in Exhibit G.

            14.1.4 Software Fixes. In the event that any Software Maintenance
Release, Software Upgrade, Software Enhancement or Software Combined Release
supplied by the Vendor during the term of this Contract has the effect of
preventing any System or any part thereof from satisfying, or performing in
accordance with the Specifications or the Exhibits or otherwise adversely
affects the functionality or features of any System or any part thereof, then
the Vendor shall promptly retrofit or take such other corrective action as may
be necessary to ensure that any System or any such affected part, as modified to
include each


                                       33
<PAGE>   48
such Software Maintenance Release, Software Upgrade, Software Enhancement or
Software Combined Release, shall satisfy, and perform in accordance with, the
Specifications and the Exhibits and restore all pre-existing functionality and
features as well as provide any new features and functionality provided by any
of the foregoing modifications, in each case without any charge to the Owner
(other than payment of the applicable fees pursuant to the terms of this
Contract). Notwithstanding anything contained herein in this subsection to the
contrary, Owner shall be responsible for the cost of any additional Equipment
required to accommodate additional capacity, memory or processing requirements
necessitated by any new Software feature or Optional Software Feature which
Owner elects to use (provided such use by Owner is optional without losing the
benefit of the Software Maintenance Release or Software Upgrade) which are
contained in any such Software Upgrade, Software Enhancement or Software
Combined Release; provided, however, that Owner shall not be required to pay for
any additional Equipment required to accommodate additional capacity, memory or
processing requirements necessitated by implementation of a required Software
Maintenance Release, whether or not such Software Maintenance Release is issued
as a stand-alone release, or is contained within a Software Upgrade, Software
Enhancement or Software Combined Release.

            14.2 Equipment.

            14.2.1 Equipment Upgrades. (a) Equipment Upgrades will be provided
to the Owner by the Vendor at no charge to the Owner as provided in subsection
14.2.1(b) below. Equipment Enhancements must be provided to the Owner by the
Vendor, if requested by the Owner, and the Owner is obligated to make payment
therefor in an amount that is specified on the B Exhibits. If the Vendor at any
time issues an Equipment Upgrade which is combined with any Equipment
Enhancement (collectively, the "Equipment Combined Release") to such Equipment,
the Equipment Combined Release will be provided at no charge to the Owner unless
and until the Owner uses any of the Equipment Enhancements included within the
Equipment Combined Release, provided such use by Owner of such Equipment is
optional without losing the benefit of the Equipment Upgrade.

            (b) (i) After a Product has been shipped to the Owner, if the Vendor
issues an Equipment Upgrade or Equipment Enhancement, or where a modification to
correct an error in field documentation is to be introduced, the Vendor will
promptly notify the Owner of such change through the Vendor's design change
management system or another Vendor notification procedure. Each change
notification, whether or not it bears a restrictive legend, will be subject to
the confidentiality obligations provided in subsection 26.18, except that such
information may be reproduced by the Owner for the Owner's use as required
within the System. If the Vendor has engineered, furnished, and installed a
Product which is subject to an Equipment Upgrade, the Vendor will implement such
change, at its sole cost and expense, if it is announced within [*] for the AXE
switch and [*] for all other Products from the date of shipment of that Product,
and subject to the reasonable review and acceptance of the Owner at such times
as the Owner reasonably determines that it needs to review such Vendor decision,
by either (A) modifying the Product at the Owner's site; (B) modifying the
Product which the Owner has returned to the Vendor in accordance with the
Vendor's reasonable instructions pursuant to and in

[*]  Certain material (indicated by an asterisk) has been omitted from this
     document pursuant to a request for confidential treatment. The omitted
     material has been filed separately with the Securities and Exchange
     Commission.

                                       34
<PAGE>   49
accordance with the terms of this Contract; or (C) replacing the Product
requiring the change with a replacement Product for which such change has
already been implemented. If the Vendor has not engineered the original Product
application and accordingly office records are not available to the Vendor, the
Vendor will provide the generic change information and associated parts for the
Owner's use in implementing such change.

            (ii) In any of the instances described in clause (i) above, if the
Vendor and the Owner agree that a Product or part thereof subject to such change
is readily returnable, without incurring any significant time or expense, the
Owner, at its expense, will remove and return such Product or part to the
Vendor's designated facility within the United States and the Vendor, at its
sole expense, will implement such change (or replace it with a Product or part
for which such change has already been implemented) at its facility and return
such changed (or replacement) Product or part at its sole cost and expense to
the Owner's designated location within the United States. Any such
reinstallation of Products which were readily returnable will be performed by
the Owner at its sole expense, provided such reinstallation can be done by Owner
without incurring any significant time or expense. In all other circumstances,
Vendor shall provide such removal, repair and reinstallation Services at its
sole cost and expense.

            (iii) If the Owner does not make or permit the Vendor to make an
Equipment Upgrade as stated above within the appropriate [*] or [*] period from
the date of change notification or such other period as the Vendor may agree,
subsequent changes, repairs or replacements affected by the failure to make such
change may, at the Vendor's option, be invoiced to the Owner whether or not such
subsequent change, repair or replacement is covered under the warranty provided
in this Contract for such Product. If requested by the Owner, Equipment Upgrades
announced more than the appropriate [*] or [*] period from the date of shipment
will be implemented at the Owner's expense.

            (iv) If the Vendor issues an Equipment Enhancement after a Product
has been shipped to the Owner, the Vendor will promptly notify the Owner of such
change if it is being offered to any of the Vendor's customers. Except as
otherwise set forth above in subsection 14.2(b), when an Equipment Enhancement
is requested by the Owner, the pricing set for such Equipment Enhancements will
be at the Vendor's standard charges subject to the applicable discounts set
forth in the B Exhibits.

            (v) All change notifications for Equipment Upgrades and Equipment
Enhancements provided by the Vendor to the Owner pursuant to the terms of this
Contract must contain the following information: (A) a detailed description of
the change; (B) the reason for the change; (C) the effective date of the change;
and (D) the implementation schedule for such change, if appropriate.

            14.2.2 Notice. The Vendor shall give, or shall cause to be given to,
the Owner not less than ninety (90) days prior written notice of the
introduction of any Equipment Enhancement or any Equipment Combined Release. In
addition, in each February and August of each year during the Term of this
Contract, the Vendor shall

    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       35
<PAGE>   50
provide the Owner with a forecast of future Equipment Enhancements to the
Equipment or Equipment Combined Releases then currently being developed by or on
behalf of the Vendor.

            14.2.3 Installation, Testing and Acceptance The Installation and
testing of the Equipment by the Vendor and the acceptance thereof by the Owner
shall be performed in accordance with the Exhibits and pursuant to the
Milestones contained in the Exhibits.

            14.2.4 Equipment Fixes. In the event that any Equipment Upgrade or
Equipment Enhancement, directly or indirectly, supplied by the Vendor during the
appropriate [*] or [*] period following the Effective Date or during [*] period
following the date of shipment of such Equipment Upgrade or Equipment
Enhancement, has the effect of preventing any System or any part thereof from
satisfying, or performing in accordance with, the Specifications or otherwise
adversely affects the functionality, interoperability or features of any System,
or any part thereof then the Vendor shall without any charge to the Owner
promptly retrofit or take such other corrective action as may be necessary to
assure that any System or any such affected part, as modified to include each
such Equipment Upgrade and Equipment Enhancement, shall satisfy, and perform in
accordance with, the Specifications and restore all pre-existing functionality
and features as well as provide any features and functionality provided by any
of the foregoing modifications.

            14.2.5 Equipment Backwards Compatibility Warranty. The Vendor
represents and warrants (the "Equipment Backwards Compatibility Warranty") that
each New Equipment Release will be Backwards Compatible, provided that it is
implemented within the specified time provided with each New Equipment Release.
[***] Notwithstanding the foregoing, the Equipment Backwards Compatibility
Warranty does not apply to Products developed beyond AXE standards not yet
finalized as of the date hereof.

            14.3 Notice of Developments.

            14.3.1 Vendor Developments. The Vendor shall provide the Owner, or
cause to be provided to the Owner, through the Owner's chief executive officer,
with reasonable written notice of any Product developments, innovations and/or
technological advances (collectively "Vendor Developments") relevant to the
System simultaneous to giving such notice to any other customer or otherwise
making any such Vendor Development public; provided that the Vendor shall not be
obligated to provide the Owner such notice before any other customer if doing so
would breach any contractual obligation to any other customer, provided further
that any such notice need not include any information originated by another
customer of Vendor which is proprietary to such other

[*] Certain material (indicated by an asterisk) has been omitted from this
    document pursuant to a request for confidential treatment. The omitted
    material has been filed separately with the Securities and Exchange
    Commission.

                                       36
<PAGE>   51
customer of Vendor. For the purposes of this subsection the term "Vendor"
includes the Vendor and its affiliates and subsidiaries.

            14.3.2 Participation in Testing. The Owner has the right, but not
the obligation, to witness and/or participate in any initial testing; provided
that any such initial testing of Vendor Developments shall be subject to: (i)
scheduling as reasonably determined by the Vendor; (ii) the qualification that
the Owner's System meets the technical requirements for the testing of such
Vendor Development as reasonably determined by the Vendor (or otherwise that the
Owner is willing to update such System to meet such requirements); (iii) the
Owner's acknowledgment that it shall be able to provide the resources necessary
to implement the initial testing for such Vendor Development; and (iv) the Owner
and the Vendor executing a verification office testing agreement that identifies
the scope, terms, pricing, responsibilities and schedule related to the initial
testing of such Vendor Development. The Vendor shall provide the Owner at least
thirty (30) days prior written notice of its intent to test any such Vendor
Development and upon the Owner's written request the Vendor shall allow the
Owner to participate in such testing upon terms and in a testing environment
reasonably acceptable to the parties at such time. Such rights shall not apply
to a Vendor Development originated by another customer of Vendor which includes
information which is proprietary to such other customer.

            14.3.3 Quarterly Notices. Vendor shall make reasonable efforts to
collect and distribute on a quarterly basis a list of new Software bugs,
problems, fixes, etc., provided that Vendor shall not be required to distribute
confidential information of any other customer.

            SECTION 15. INTELLECTUAL PROPERTY

            15.1 Intellectual Property. Neither Owner nor Vendor shall publish
or use any advertising, sales promotion, press releases or publicity matters
relating to this Contract without the prior written approval of the other, in
accordance with subsection 26.13.

            15.2 Infringement. (a) The Vendor agrees that it shall defend,
indemnify and hold harmless, at its own expense, all suits and claims against
the Owner for infringement or violation of any patent, trademark, copyright,
trade secret or other intellectual property rights of any third party
enforceable in the United States or in any other territory where Vendor has
approved the deployment or use of Products under this Contract (collectively,
"Intellectual Property Rights"), covering, or alleged to cover, the Products or
any component thereof. The Vendor agrees that it shall pay all sums, including
without limitation, reasonable attorneys' fees and other costs incurred at
Vendor's written request or authorization, which, in defense of, by final
judgment or decree, or in settlement of any suit or claim to which the Vendor
agrees, may be assessed against, or incurred by, the Owner on account of such
infringement or violation, provided that the Owner shall cooperate in all
reasonable respects with the Vendor and its attorneys in the investigation,
trial and defense of such lawsuit or action and any appeal arising therefrom;
provided, however, that the Owner may, at its own cost, participate in the
investigation, trial and defense of


                                       37
<PAGE>   52
such lawsuit or action and any appeal arising therefrom. The parties shall
cooperate with each other in any notifications to insurers. If a claim for
Losses (a "Claim") is to be made by a party entitled to indemnification
hereunder against the Vendor, the party claiming such indemnification shall give
written notice (a "Claim Notice") to the Vendor as soon as practicable after the
party entitled to indemnification becomes aware of any fact, condition or event
which may give rise to Losses for which indemnification may be sought under this
Agreement, provided, however, no delay on the part of the Owner in notifying the
Vendor shall relieve the Vendor from any obligation hereunder unless (and then
solely to the extent) the Vendor is thereby materially prejudiced. If any
lawsuit or enforcement action is filed against any party entitled to the benefit
of indemnity hereunder, written notice thereof shall be given to the Vendor as
promptly as practicable (and in any event within twenty (20) calendar days after
the service of the citation or summons). The Vendor shall be entitled, if it so
elects to: (i) defend such lawsuit or action; (ii) employ and engage attorneys
of its own choice to handle and defend the same, at the Vendor's cost, risk and
expense; and (iii) compromise or settle such Claim, which compromise or
settlement shall be made only with the written consent of the Owner (which may
not be unreasonably withheld), unless such compromise or settlement includes an
unconditional release of any claims against the Owner in which event such
written consent of the Owner shall not be required. If the Vendor fails to
assume the defense of such Claim within twenty (20) calendar days after receipt
of the Claim Notice, the Owner against which such Claim has been asserted will
(upon delivering notice to such effect to the Vendor) have the right to
undertake, at the Vendor's cost and expense, the defense, compromise or
settlement of such Claim on behalf of and for the account and risk of the
Vendor. In the event the Owner assumes the defense of the Claim, the Owner will
keep the Vendor reasonably informed of the progress of any such defense,
compromise or settlement. The Vendor shall be liable for any settlement of any
action effected pursuant to and in accordance with this Agreement and for any
final judgment (subject to any right of appeal), and the Vendor agrees to
indemnify and hold harmless the Owner from and against any Losses by reason of
such settlement or judgment.

            (b) The Vendor's obligation under this subsection shall not extend
to alleged infringements or violations that arise because the Products provided
by the Vendor are used in combination with other products furnished by third
parties and where any such combination was not installed, recommended or
approved by the Vendor.

            15.3 Vendor's Obligation to Cure. If in any such suit so defended,
all or any part of the Products or any component thereof is held to constitute
an infringement or violation of Intellectual Property Rights of others and its
use is enjoined, or if in respect of any claim of infringement or violation the
Vendor deems it advisable to do so, the Vendor shall at its sole cost, expense
and option take one or more of the following actions: (i) procure the right to
continue the use of the same without interruption for the Owner; (ii) replace
the same with non-infringing Products that meets the Specifications in
accordance with the terms of this Contract; or (iii) modify said Products, any
System or any component thereof so as to be non-infringing, provided that the
Products, any System or any component thereof as modified meets all of the
Specifications. In the event that the Vendor is not able to cure the
infringement pursuant to clause (i), (ii) or (iii) in the immediately preceding


                                       38
<PAGE>   53
sentence, in addition to the other rights and remedies provided in this Section
15, the Vendor shall refund to the Owner the full purchase price paid by the
Owner for such infringing Product or feature, and the Owner shall be under no
obligation to return to the Vendor such infringing Product or feature regardless
of whether, or by what means, the Owner, on its own or otherwise, subsequently
cures such infringement, unless Owner is directed to do so by court order.

            15.4 Vendor's Obligations. The Vendor's obligations under this
Section 15 shall not apply to any infringement or violation of Intellectual
Property Rights caused by unauthorized modification of the Products, any System
or any component thereof by the Owner, or arises from adherence to instructions
to apply Owner's trademark, trade name or other company identification to a
Product, or any infringement caused solely by the Owner's use and maintenance of
the Products other than in accordance with the Specifications, except as
authorized or permitted by the Vendor. The Owner shall indemnify the Vendor
against all liabilities and costs, including reasonable attorneys' fees, for
defense and settlement of any and all claims against the Vendor for
infringements or violations based upon this subsection.

            15.5 Liability of Vendor. The Liability of Vendor with respect to
any and all claims, actions, proceedings or suits by third parties alleging
infringement of patents, trademarks, or copyrights or violation of trade secrets
or proprietary rights because of, or in connection with, any items furnished
pursuant to this Contract shall be limited to the specific undertakings
contained in this Section 15.

            SECTION 16. DELAY

            16.1 Liquidated Damages. The parties agree that damages for delay
are difficult to calculate accurately and not reasonably determinable at the
time of execution of this Contract, and, therefore, agree that liquidated
damages (the "Liquidated Damages") shall be paid for non-performance or late
performance of the Vendor's obligations to achieve a Guaranteed Substantial
Completion Date for reasons not otherwise excused by Force Majeure or Owner's
failure to satisfy its obligations set out in this Contact. The parties agree
that Liquidated Damages are intended to compensate Owner for the delayed or late
performance by the Vendor and are not a penalty.

            16.2 Delay and Default. In the event the Vendor fails to achieve
(other than as permitted by this Contract) the Substantial Completion of a
System on or before the Guaranteed Substantial Completion Date for such System
or during a ten day cure period following such date, the Vendor shall pay,
weekly in arrears, for the next [*] commencing on the eleventh day after the
Guaranteed Substantial Completion Date, Liquidated Damages to the Owner in an
amount equal to [*] (pro-rated on a daily basis for periods of time less than
one week) of the total amount of all Purchase Orders relating to the System with
respect to which the Vendor has so failed, based on the number of days elapsed
after a ten day cure period following the Guaranteed Substantial Completion Date
and before the achievement of Substantial Completion;

[*]  Certain material (included by an asterisk) has been omitted from this
     document pursuant to a request for confidential treatment. The omitted
     material has been filed separately with the Securities and Exchange
     Commission.


                                       39
<PAGE>   54
provided that in the event that Substantial Completion is not achieved prior to
the expiration of such [*] period, thereafter Vendor shall pay, weekly in
arrears, additional Liquidated Damages to the Owner in an amount equal to [*]
(pro-rated on a daily basis for periods of time less than one week) of the total
amount of all Purchase Orders relating to the System with respect to which the
Vendor has so failed, based on the number of days elapsed after the [*]
plus ten day cure period following the Guaranteed Substantial Completion Date
and before the achievement of Substantial Completion; provided that in no event
shall the amount of Liquidated Damages so paid in respect of a System exceed [*]
of the total amount of all Purchase Orders relating to the System with respect
to which the Vendor has so failed.

            16.3 System Capacity Guarantee. [***]

            16.4 Limitation. The foregoing provisions concerning Liquidated
Damages shall not be deemed to limit the amount payable by the Vendor to the
Owner for breach of contract, except for amounts payable on account of delay as
aforesaid, provided, however


[*]  Certain material (indicated by an asterisk) has been omitted from this
     document pursuant to a request for confidential treatment. The omitted
     material has been filed separately with the Securities and Exchange
     Commission.


                                       40
<PAGE>   55
that the payment of Liquidated Damages shall be Owner's sole remedy for the
delay giving rise to the Vendor's obligation to pay the Liquidated Damages.

            16.5 Early Completion Bonus. With respect to a System, Vendor shall
be entitled to an early completion bonus from the Owner in the event that
Substantial Completion with respect to such System occurs on or prior to the
date that is [*] prior to the Guaranteed Substantial Completion Date for such
System. Such early completion bonus shall be equal to [*] (pro-rated on a daily
basis for periods of time less than one week) of the total amount of all
Purchase Orders relating to such System, based on the number of days that
Substantial Completion occurs prior the date that is [*] prior to the Guaranteed
Substantial Completion Date for such System.

            SECTION 17. FORCE MAJEURE

            17.1 Excusable Delay. (a) If the performance of this Contract, or of
any obligation hereunder except for the obligations set forth in Section 5 is
prevented, restricted or interfered with by reason of fires, breakdown of plant,
labor disputes, embargoes, government ordinances or requirements, civil or
military authorities, acts of God or of the public enemy, acts or omissions of
carriers, inability to obtain necessary materials or services from suppliers, or
other causes beyond the reasonable control of the party whose performance is
affected ("Force Majeure"), then the party affected, upon giving prompt notice
to the other party, shall be excused from such performance on a day-for-day
basis to the extent of such prevention, restriction, or interference (and the
other party shall likewise be excused from performance of its obligations on a
day-for-day basis to the extent such party's obligations relate to the
performance so prevented, restricted or interfered with); provided that the
party so affected shall use reasonable efforts to avoid or remove such cause of
non-performance and both parties shall proceed to perform their obligations with
dispatch whenever such causes are removed or cease.

            (b) The party claiming the benefit of excusable delay hereunder
shall: (i) promptly notify the other party of the circumstances creating the
failure or delay and provide a statement of the impact of such party failure or
delay; and (ii) use reasonable efforts to avoid or remove such causes of
nonperformance, excusable failure or delay. If an event of Force Majeure
prevents the Vendor from performing its obligations under this affected Purchase
Orders for a period exceeding sixty (60) days, the Owner may, upon prior written
notice to the other party, terminate any affected Purchase Orders; however, this
Contract remains in full force and effect. [To be negotiated.]

            (c) In the event of a Force Majeure which the party claiming relief
for such event has used all best efforts to resolve in accordance with the terms
of this Contract, upon the written request of either party, the other party
shall in good faith negotiate modifications, to the extent reasonable and
necessary, in scheduling and performance criteria in order to reasonably address
the impact of such Force Majeure.

            SECTION 18. WARRANTIES

            18.1 Equipment and Services Warranty. Vendor warrants that, with
respect to each System, for a period of two (2) years from the date of
Substantial Completion, provided, however that if prior to Final Acceptance a
Major Outage occurs, the two (2) year period shall be extended by the number of
days elapsed between Substantial Completion and the date the Owner signs the
Certificate of Final Acceptance (as so determined, the "Warranty Period"), all
Equipment and Services furnished under this Contract with respect to such System
will be free of Defects and Deficiencies and shall conform to the applicable
portions of the Specifications (the "Equipment and Services Warranty"),
provided, however, that with respect to those Services for which a warranty is
set forth in an Exhibit, the warranty contained in the Exhibit shall supersede
the general Services warranty contained in this Section 18.1. With respect to
third-party manufactured Products which are not a part of a Core System, Vendor
shall furnish such Products only on a pass-through warranty basis; provided,
however, that Vendor shall identify such Products to Owner before acceptance of
any Purchase Order which includes any such Products. The terms of the warranty
applicable to such Products shall be provided in an addendum to the Purchase
Order. Except as noted in the B Exhibits, all Products referenced in the B
Exhibits qualify as Vendor-warranted Products. The Vendor's obligations with
respect to the Equipment and Services Warranty shall be to attempt first to
repair or replace at no additional cost, any defective Equipment or correct any
deficient Services. If, after using its best efforts to repair or replace such
Product and after consultation with and with the consent of Owner, which consent
shall not be unreasonably withheld, Vendor determines that it is unable to
repair, replace or otherwise correct such defect, Vendor shall provide a credit
or refund based on the original purchase price, and installation charges if
installed by Vendor. If, as a result of the Defect and Deficiency, the Product
fails to operate in accordance with the Specifications which causes the System
to fail to materially operate in accordance with its Specifications, a refund
shall be paid to the Owner on account of the purchase price for the total
System, less a pro-rata discount calculated with regard to the period of time
during the Warranty Period that Owner operated the System in In Revenue Service.
For purposes of calculating such pro rata discount, the period of time the Owner
would have been able to operate the System within In Revenue Service shall be:
(i) ten (10) years from Substantial Completion for the AXE switch; and (ii)
seven (7) years from Substantial Completion for all other Products. In the event
that Vendor pays a refund hereunder, Owner shall return such Products to Vendor
at Vendor's sole cost and expense. The Warranty Period for all Equipment or
Services repaired, replaced or corrected under the Equipment and Services
Warranty shall be the longer of: (i) one (1) year from the date of delivery of
the repaired or replacement Equipment or from the completion of the corrected
Services, as applicable; or (ii) or the unexpired term of the Warranty Period.
The Warranty Period for Equipment purchased as spares shall be two (2) years
from installation of such Equipment.

      For those Products not readily returnable by Owner, or where Owner cannot
remove and reinstall the Products without incurring significant time and
expense, and where Vendor elects to repair or replace the Product, Vendor shall
repair or replace the Product at Owner's Site. In the event Vendor does the
repair work at Owner's site, Vendor shall be responsible


                                       42
<PAGE>   57
for replacement of cable and wire Products, and for reasonable Site restoration.
If Vendor has elected to repair or replace a defective Product, and the Product
is readily returnable by Owner without incurring significant work or expense,
Owner is responsible for removing and reinstalling the Products. Products
returned for repair or replacement will be accepted by Vendor only in accordance
with its instructions and procedures for such returns. The transportation
expense associated with returning such Product to Vendor shall be borne by
Owner. Vendor shall pay the cost of transportation of the repaired or replacing
Product to the return destination designated by Owner. Defective or
nonconforming Products or parts which are replaced hereunder shall become
Vendor's property. Vendor may use either the same or functionally equivalent
new, remanufactured, reconditioned or refurbished Products or parts in the
furnishing of repairs or replacements under this Contract, provided that such
Products satisfy the Specifications.

            18.2 Expansions Warranty. Vendor warrants that, with respect to
Products and Services constituting Expansions (including Expansions to a System,
or Expansions or growth not part of a System, and all other purchased Products)
furnished under this Contract will be free of Defects and Deficiencies and shall
conform the applicable portions of the Specifications (the "Expansions
Warranty"). The warranty period with respect to such Products and Services shall
be two (2) years from the date of installation completion or completion of
Services, as the case may be (the "Expansions Warranty Period"). With respect to
third-party manufactured Products which are not a part of a Core System, Vendor
shall furnish such Products only on a pass-through warranty basis; provided,
however, that Vendor shall identify such Products to Owner before acceptance of
any Purchase Order which includes any such Products. The terms of the warranty
applicable to such Products shall be provided in an addendum to the Purchase
Order. Except as noted in the B Exhibits, all Products referenced in the B
Exhibits qualify as Vendor-warranted Products. The Vendor's obligations with
respect to the Expansions Warranty shall be to attempt first to repair or
replace at no additional cost, any defective Equipment or correct any deficient
Services. If, after using its best efforts to repair or replace such Product and
after consultation with and with the consent of Owner, which consent shall not
be unreasonably withheld, Vendor determines that it is unable to repair, replace
or otherwise correct such defect, Vendor shall provide a credit or refund based
on the original purchase price, and installation charges if installed by Vendor.
The warranty period for all Equipment or Services repaired, replaced or
corrected under the Expansions Warranty shall be the longer of: (i) one (1) year
from the date of delivery of the repaired or replacement Equipment or from the
completion of the corrected Services, as applicable; or (ii) or the unexpired
term of the Expansions Warranty Period. The Warranty Period for Equipment
purchased as spares shall be two (2) years from installation of such Equipment.

      For those Products not readily returnable by Owner, or where Owner cannot
remove and reinstall the Products without incurring significant time and
expense, and where Vendor elects to repair or replace the Product, Vendor shall
repair or replace the Product at Owner's Site. In the event Vendor does the
repair work at Owner's site, Vendor shall be responsible for replacement of
cable and wire Products, and for reasonable Site restoration. If Vendor has
elected to repair or replace a defective Product, and the Product is readily
returnable by Owner without incurring significant work or expense, Owner is
responsible for removing


                                       43
<PAGE>   58
and reinstalling the Products. Products returned for repair or replacement will
be accepted by Vendor only in accordance with its instructions and procedures
for such returns. The transportation expense associated with returning such
Product to Vendor shall be borne by Owner. Vendor shall pay the cost of
transportation of the repaired or replacing Product to the return destination
designated by Owner. Defective or nonconforming Products or parts which are
replaced hereunder shall become Vendor's property. Vendor may use either the
same or functionally equivalent new, remanufactured, reconditioned or
refurbished Products or parts in the furnishing of repairs or replacements under
this Contract, provided that such Products satisfy the Specifications.

            18.3 Software Warranty. Vendor warrants that, with respect to each
System for the Warranty Period, all Software will be free of Defects and
Deficiencies and shall conform to the applicable portions of the Specifications
(the "Software Warranty"). The Vendor's obligations with respect to the Software
Warranty shall be to attempt first to repair or replace at no additional cost,
any defective Software. If, after using its best efforts to repair or replace
such Software and after consultation with and with the consent of Owner, which
consent shall not be unreasonably withheld, Vendor determines that it is unable
to repair, replace or otherwise correct such defect, Vendor shall provide a
credit or refund based on the original purchase price, and installation charges
if installed by Vendor. If, as a result of the Defect and Deficiency, the
Software fails to operate in accordance with the Specifications which causes the
System to fail to materially operate in accordance with its Specifications, a
refund shall be paid to Owner on account of the purchase price for the total
System, less a pro rata discount calculated with regard to the period of time
during the Warranty Period that Owner operated the System in In Revenue Service.
For purposes of calculating such pro rata discount, the period of time the Owner
would have been able to operate the System in In Revenue Service shall be: (i)
ten (10) years from Substantial Completion for the AXE switch; and (ii) seven
(7) years from Substantial Completion for all other Products. In the event that
Vendor pays a refund hereunder, Owner shall return such Products to Vendor. The
warranty period for all Software so corrected or replaced under the Software
Warranty shall be the longer of: (i) one (1) year from the date of delivery of
the repaired or replacement Software; or (ii) or the unexpired term of the
Warranty Period. Vendor shall be solely responsible for all costs and expenses
incurred by Owner or Vendor in connection with the de-installation, removal and
transportation of defective Software under the Software Warranty and for the
transportation and installation of repaired, corrected or replacement Software,
including without limitation any additional or upgraded Equipment or processing
capability necessary to run or operate such repaired, corrected or replacement
Software. The Warranty Period with respect to Software Maintenance Releases,
Software Upgrades, Software Enhancements and Software Combined Releases shall be
two (2) years from the successful installation [To be negotiated.] of such
Software Maintenance Releases, Software Upgrades, Software Combined Releases and
Software Enhancements.

successors and assigns, from Losses and threatened Losses arising from, in
connection with, or based on allegations of, any of the following:

            (a)   Vendor's failure to observe or perform any duties or

                  conduct (including without limitation negligence, willful
                  misconduct or breach of warranty) or strict liability of
                  Vendor, any Subcontractor


                                       46
<PAGE>   61
                  or its or their respective employees, contractors, agents or

                  without limitation negligence, willful misconduct or breach of
                  warranty) or strict liability of Vendor, any Subcontractor or
                  its or their respective employees, contractors, agents or
                  representatives; or

            (d)   any claim, demand, charge, action, cause of action or other
                  proceeding asserted against Owner but arising out of or

                  or its or their respective employees, contractors, agents or
                  representatives in its or their respective capacities as an
                  employer.

            20.2 Claim for Losses. If a Claim is to be made by a party entitled
to indemnification hereunder against the Vendor, the party claiming such
indemnification shall give a Claim Notice to the Vendor as soon as practicable

under this Agreement, provided, however, no delay on the part of the Owner in
notifying the Vendor shall relieve the Vendor from any obligation hereunder

which compromise or settlement shall be made only with the written consent of
the Owner (which may not be unreasonably withheld), unless such compromise or
settlement includes an unconditional release of any claims against the Owner in
which event such written consent of the Owner shall not be required. If the
Vendor fails to assume the defense of such Claim within twenty (20) calendar
days after receipt of the Claim Notice, the Owner against which such Claim has
been asserted will (upon delivering notice to such effect to the Vendor) have
the right to undertake, at the Vendor's cost and expense, the defense,
compromise or settlement of such Claim on behalf of and for the account and risk
of the Vendor. In the event the Owner assumes the defense of the Claim, the
Owner will keep the Vendor reasonably informed of the progress of any such
defense, compromise or settlement. The Vendor shall be liable for any settlement
of any action effected pursuant to and in accordance with this Agreement and for
any final judgment (subject to any right of appeal), and the Vendor agrees to
indemnify and hold harmless the Owner from and against any Losses by reason of
such settlement or judgment.

CLAIM, LOSS, DAMAGE OR EXPENSE OF OWNER OR ANY OTHER

      or a casualty which is fully covered by insurance or as to which other
      provisions reasonably acceptable to the Owner are being diligently
      pursued); or

            (f) the Vendor assigns or subcontracts Work other than as provided
      for in this Contract which has a Material Adverse Effect; or

            (g) the Vendor misses the Guaranteed Substantial Completion Date for
      any given System by a period in excess of one hundred-fifty (150) days;
      provided that in such case the Owner shall have the right, but not the
      obligation, to terminate this Contract with respect to only that System in
      which such delay occurred; and provided further that such failure to
      achieve such date was not caused by: (i) a Force Majeure event; and/or
      (ii) any act or omission of the Owner; or

            (h) if an event of Force Majeure prevents the Vendor from performing
      its obligations under this Contract for a period exceeding sixty (60)
      days, the Owner may, upon prior written notice to the Vendor, terminate
      this Contract in accordance with the Force Majeure provisions above; or

            (i) the Vendor otherwise materially breaches any provision of this
      Contract.

            24.3 Remedies. (a) If any of the Vendor Events of Default exists,
the Owner may, in addition to and without prejudice to any other rights or
remedies of the Owner in this Contract or at law or in equity, terminate this
Contract upon written notice to the Vendor; provided, however, that the Owner
shall have first provided to the Vendor the following periods of notice and
opportunity to cure:


                                       52
<PAGE>   67
                  (i) in the case of a Vendor Event of Default specified in the
      foregoing clauses (a) or (b), no notice or opportunity to cure shall be
      required from the Owner; and

                  (ii) in the case of any other Vendor Event of Default, the
      Owner shall have provided thirty (30) days' prior written notice, and the
      Vendor shall have failed to: (i) commence to cure the default within five
      (5) Business Days of delivery of such notice; and (ii) diligently pursue
      such cure and remedy the breach entirely.

            (b) If the Owner elects to terminate this Contract, the Owner may,
in addition to and without prejudice to any other rights or remedies of the
Owner in this Contract or of law or in equity, do one or more of the following:

                  (i) require Vendor, at no additional charge to Owner, to
      complete or assist others with the completion of all ordered but
      unfinished Work, including the sharing with Owner and others all relevant
      engineering and design data, procurement data, manufacturing data,
      construction and erection data, start-up and testing data, materials, and
      Products that shall become part of such unfinished System and/or the
      specified Systems, which Vendor would otherwise have been required to
      deliver to Owner pursuant to the terms of this Contract but for the
      breach, under reasonably appropriate non-disclosure agreements; or

                  (ii) direct that the Vendor assign its Subcontractor
      agreements to the Owner without any change of price or conditions therein
      or penalty or payment therefor.

            (c) In the event of any termination of this Contract by Owner in
connection with a Vendor Event of Default, Owner shall have no liability for any
failure to satisfy the Minimum Purchase Commitment prior to such termination.

            24.4 Discontinuance of Work. Upon such notification of termination,
the Vendor shall immediately discontinue all of the Work (unless such notice of
termination directs otherwise), and, as more fully set forth in subsection
24.3(b), deliver to the Owner copies of all data, drawings, specifications,
reports, estimates, summaries, and such other information, and materials as may
have been accumulated by the Vendor in performing the Work, whether completed or
in process, which Vendor would otherwise have been required to deliver to Owner
pursuant to this Contract but for the breach. Furthermore, the Vendor shall
assign, assemble and deliver to the Owner all purchase orders and Subcontractor
agreements requested by the Owner.

            24.5 Payments. If the Owner terminates this Contract pursuant to
subsection 24.2, the Vendor shall not be entitled to receive further payment
other than payments due and payable under this Contract and not subject to
dispute prior to such termination (provided that any such disputed amounts shall
be paid by the Owner when and if such dispute is in fact resolved).
Notwithstanding anything herein to the contrary, the Owner may withhold
payments, if any, to the Vendor for the purposes of offset of amounts


                                       53
<PAGE>   68
owed to the Owner pursuant to the terms of this Contract until such time as the
exact amount of damages due the Owner from the Vendor is fully determined by a
court of competent jurisdiction.

            24.6 Continuing Obligations. Termination of this Contract for any
reason (i) shall not relieve either party of its obligations with respect to the
confidentiality of the Proprietary Information as set forth in subsection 26.18;
(ii) shall not relieve either party of any obligation which applies to it and
which expressly or by implication survives termination; and (iii) except as
otherwise provided in any provision of this Contract expressly limiting the
liability of either party, shall not relieve either party of any obligations or
liabilities for loss or damage to the other party arising out of or caused by
acts or omissions of such party prior to the effectiveness of such termination
or arising out of its obligations as to portions of the Work already performed
or of obligations assumed by the Vendor prior to the date of such termination.

            24.7 Vendor's Right to Terminate. The Vendor shall have the option
to terminate this Contract without any penalty or payment obligations, other
than undisputed payment obligations outstanding as of the date of any such
termination pursuant to the terms of this Contract if:

            (a) the Owner (i) files a voluntary petition in bankruptcy or has an
      involuntary petition in bankruptcy filed against it that is not dismissed
      within sixty (60) days of such involuntary filing: (ii) admits the
      material allegations of any petition in bankruptcy filed against it; (iii)
      is adjudged bankrupt; (iv) makes a general assignment for the benefit of
      its creditors, or if a receiver is appointed for all or a substantial
      portion of its assets and is not discharged within sixty (60) days after
      his appointment; or (v) commences any proceeding for relief from its
      creditors in any court under any state insolvency statutes, and any such
      filing, proceeding, adjudication or assignment as described herein above
      shall otherwise materially impair the Owner's ability to perform its
      obligations under this Contract; or

            (b) the Owner fails to make payments of undisputed amounts due to
      the Vendor pursuant to the terms of this Contract which are more than
      sixty (60) days overdue, provided that such failure has continued for at
      least thirty (30) days after the Vendor has notified the Owner of its
      right and intent to so terminate on account of such overdue amount; and
      provided, further, that such failure to make undisputed payments to Vendor
      shall not arise out of or relate to a termination of or credit
      restrictions under the Vendor Financing, or

            (c) the Owner materially breaches any provision of this Contract
      other than a breach to which subsection 24.7(b) is applicable, and after
      the Vendor having provided thirty (30) days' prior written notice, the
      Owner shall have failed to: (i) commence to cure the default within five
      (5) Business Days of delivery of such notice; and (ii) diligently pursue
      such cure and remedy the breach entirely.

            24.8 Special Termination Events. (a) Neither the Vendor nor the
Owner shall be obligated to perform under this Contract, except as specifically
provided, in the event that financing for the purpose of acquiring any System
sufficient to cover Owner's current payment obligations hereunder has not been
finalized with the Vendor on terms and conditions reasonably satisfactory to the
Owner. Unless acceptable financing is available, either party may terminate this
Contract without recourse, except as noted below, by notifying the other party
in writing. Further, the parties agree that the delivery and performance
schedules shall be extended by the period of time required to secure acceptable
financing. In the event of a termination of this Contract pursuant to this
subsection the Owner shall remain liable for amounts due to the Vendor for all
Work performed or Products delivered by the Vendor or any of its Subcontractors
pursuant to the specific terms of this Contract which had been directly
delivered to or performed for the Owner and/or any of its facilities or Sites in
accordance with the terms of this Contract. Any amounts owed by the Owner for
Work done or Products delivered by the Vendor during such interim period not
otherwise invoiced to the Owner by the Vendor prior to the termination of such
interim period, shall be invoiced to the Owner by the Vendor within thirty (30)
days. In no event shall the Owner be liable to the Vendor due to a termination
of this Contract pursuant to this subsection for satisfaction of the Minimum
Purchase Commitment or for any of the Vendor's direct or indirect costs or
expenses incurred in connection with any supplies or equipment ordered by the
Vendor or agreements entered into by the Vendor in order to enable it to fulfill
its obligations hereunder or in connection with the establishment of and/or
upgrade to its manufacturing, personnel, engineering, administrative or other
capacities and/or resources in contemplation of or pursuant to its performance
in accordance with the terms of this Contract. Any amounts due to the Vendor
pursuant to this subsection shall be limited in all cases to Work actually done
or Products or Services actually delivered to the Owner, its Sites or its
facilities.

            (b) If at any time after the Effective Date any material change
shall have occurred in any Applicable Law or in the interpretation thereof by
any Governmental Entity, or there shall be rendered any decision in any judicial
or administrative case or proceeding, in either case which, in the reasonable
opinion of the Owner would make the Owner's use of any part of any System
illegal or would subject the Owner or any of its Affiliates to any material
penalty, other material liability or onerous condition or to any burdensome
regulation by any Governmental Entity or otherwise render the use of such System
economically nonviable, then, with respect to such System, or affected part
thereof, or with respect to all Systems if so affected, the Owner may terminate
this Contract without charge or penalty of any kind; provided that (i) the Owner
gives the Vendor prior written notice of any such change or decision and (ii)
that the Owner uses its reasonable efforts for a reasonable time to reverse or
ameliorate such change or decision to the extent possible or practical prior to
declaring such termination. In the event of a termination pursuant to this
subsection, payment obligations incurred by the Owner for Work actually done or
Products or Services actually delivered by the Vendor prior to such termination
pursuant to this Contract shall be payable by the Owner to the Vendor on the
same terms and subject to the limitations set forth in subsection 24.8(a) above.

            SECTION 25. SUSPENSION

            25.1 Owner's Right to Suspend Work. The Owner may at any time issue
a Change Order to the Vendor to suspend all or any part of the Work for such
period of time as the Owner may reasonably determine to be appropriate. Any such
Change Order shall be handled in accordance with the provisions of Section 11
hereof.

            SECTION 26. MISCELLANEOUS

            26.1 Amendments. The terms and conditions of this Contract may only
be amended by mutually agreed contract amendments. Each amendment shall be in
writing and shall identify the provisions to be changed and the changes to be
made. Contract amendments shall be signed by duly authorized representatives of
each of the Vendor and the Owner.

            26.2 Owner Liabilities. Vendor understands and agrees that no third
party shall guarantee or otherwise be in any way liable with respect to any
obligations or liabilities of the Owner or any of its affiliates pursuant to
this Contract.

            26.3 Offset. The Vendor hereby waives any right of offset of amounts
owed by the Owner to the Vendor pursuant to the terms of this Contract.

            26.4 Assignment. The Owner may assign this Contract, or any part
hereof, to any affiliate of Owner without the Vendor's approval or consent.
Subject to the foregoing and except as otherwise permitted herein, neither this
Contract nor any portion hereof may be assigned by either party without the
express prior written consent of the other party. The Owner may, without the
consent of the Vendor, collaterally assign its rights hereunder (including but
not limited to all licenses with respect to the Software) to any or all parties
providing financing for any part of a System for the benefit of the Vendor and
one or more other entities providing financing for any part of a System or
similar arrangement for the benefit of the Vendor and one or more other entities
providing for the financing for any part of a System, in either case, which
arrangement, as the case may be, is reasonably acceptable to the Vendor in
accordance with the terms of the financing documents. If requested by the Owner,
the Vendor shall within seven (7) calendar days of such request provide a
written consent to any such assignment; provided that such consent shall permit
reassignment if the financing parties exercise their remedies under the
documents for such financing subject to reasonable standards as to: (i) the
creditworthiness of the assignee; and (ii) the fact that the assignee is not at
such time a direct competitor of the Vendor involved in the manufacture of
communications equipment, software or related services. The foregoing rights and
obligations are in addition to those set forth elsewhere in this Contract. Any
attempted assignment in violation of the terms of this Contract shall be null
and void. Subject to the foregoing, this Contract shall bind and inure to the
benefit of the parties to this Contract, their successors and permitted assigns.
Notwithstanding the foregoing, Vendor shall have the right to assign this
Contract to its affiliate, Ericsson Inc.; provided however, such


                                       56
<PAGE>   71
assignment shall not relieve Vendor of its obligations hereunder or cause Owner
to incur any additional costs or expenses.

            26.5 Notices. Except as otherwise expressly stated herein, all
notices, requests, demands and other communications which are required or may be
given under this Contract shall be in writing and shall be deemed to have been
duly given when received if personally delivered; when transmitted if
transmitted by telecopy, electronic or digital transmission method; the day

recognized overnight delivery service; and three (3 ) days after sending, if

            26.12 Waiver. Unless otherwise specifically provided by the terms of
this Contract, no delay or failure to exercise a right resulting from any breach
of this Contract shall impair such right or shall be construed to be a waiver
thereof, but such right may be exercised from time to time as may be deemed
expedient. If any representation, warranty or covenant contained in this
Contract is breached by either party and thereafter waived by the other party,
such waiver shall be limited to the particular breach so waived and not be
deemed to waive any other breach under this Contract.

            26.13 Public Statements and Advertising. (a) Neither party shall
issue any public statement (or any private statement unless required in the
performance of the Work) relating to or in any way disclosing any aspect of the
Work or any System including the scope, the specific terms of this Contract,
extent or value of the Work or any System. Express written consent of the other
party is required prior to the invitation of or permission to any reporter or
journalist to enter upon the System or any part thereof. The Vendor agrees not
to use for publicity purposes any photographs, drawings and/or materials
describing any System without obtaining the prior written consent of the Owner,
which consent shall not be unreasonably withheld. The Owner agrees not to use
for publicity purposes any photographs, drawings and/or materials describing the
Vendor's products and services without obtaining the prior written consent of
the Vendor, which consent shall not be unreasonably withheld. This subsection
shall not prohibit the provision of necessary information to prospective
Subcontractors and the Vendor's or the Owner's personnel, agents or consultants
or other disclosures which are required by Applicable Law, including without
limitation federal and state securities laws and regulations. All other such
public disclosures by a party require the written consent of the other party.

            (b) Each party shall submit to the other proposed copies of all
advertising (other than public statements or press releases) wherein the name,
trademark or service mark of the other party or its affiliates is mentioned; and
neither party shall publish or use such advertising without the other party's
prior written approval. Such approval shall be granted as promptly as possible
and shall not be unreasonably withheld. The parties acknowledge that the
obtaining of prior written approval for each such use pursuant to this
subsection may be an administrative burden. At the request of either party, the

specified therein. Such guidelines shall be subject to change from time to time
at the reasonable request of either party.

            26.14 Records and Communications. Procedures for keeping and

            26.15 Ownership of Specifications. The Specifications shall
constitute the Proprietary Information of each party to the extent of each
party's contribution to the Specifications. Neither party shall use those parts
of the Specifications contributed by the other party or any part of the
Proprietary Information of the other party for any purpose other than fulfilling
or exercising their respective rights or obligations under this Agreement.

            26.16 Financing Requirements. The Vendor acknowledges that the
attainment of financing for construction of the System may be subject to
conditions that are customary and appropriate for the providers of such
financing. Therefore, the Vendor agrees to promptly consider any reasonable
amendment to or modification or assignment of this Contract required by such
providers (including, without limitation, any pertinent industrial development
authority or other similar governmental agency issuing bonds for financing of
the System) which do not materially modify the scope of the Vendor's Work in
order to obtain such financing. In the event that any such amendment or
modification materially increases the Vendor's risk or costs hereunder, the
Owner and the Vendor shall negotiate in good faith to adjust pricing matters,
and to equitably adjust such other provisions of this Contract, if any, which
may be affected thereby, to the extent necessary to reflect such increased risk
or costs. In no event shall the Vendor be required to accept any modification or
amendment pursuant to this subsection provide it has a commercially reasonable
basis for such refusal.

            26.17 Owner Review, Comment and Approval. To the extent that various
provisions of this Contract provide for the Owner's review, comment, inspection,
evaluation, recommendation or approval, the Owner may at its option do so in
conjunction and/or consultation with the Vendor. To the extent that this
Contract requires the Owner to submit, furnish, provide or deliver to the Vendor
any report, notice, Change Order, request or other items, the Owner may at its
option and upon written notice to the Vendor designate a representative to
submit, furnish, provide or deliver such items as the Owner's agent therefor. To
the extent that various provisions of this Contract provide that the Owner may
order, direct or make requests with respect to performance of the Work or is
provided access to the System sites or any other site, the Owner may at its
option and upon written notice to the Vendor authorize a representative to act
as the Owner's agent therefor. Upon receipt of such notice, the Vendor shall be
entitled to rely upon such authorization until a superseding written notice from
the Owner is received by the Vendor.

            26.18 Confidentiality. (a) All information which is identified as
proprietary or confidential by the disclosing party, including without
limitation all oral and written information (including but not limited to
determinations or reports by arbitrators pursuant to the terms of this
Contract), disclosed to the other party is deemed to be confidential, restricted
and proprietary to the disclosing party (hereinafter referred to as "Proprietary
Information"). Each party agrees to use the Proprietary Information received
from the other party only for the purpose of this Contract. Except as specified
in this Contract, no other rights, and particularly licenses, to trademarks,
inventions, copyrights, patents, or any other intellectual property rights are
implied or granted under this Contract or by the conveying of Proprietary
Information between the parties. Proprietary Information supplied is not to be
reproduced in any form except as required to accomplish the intent of, and in
accordance


                                       60
<PAGE>   75
with the terms of, this Contract. The receiving party shall provide the same
care to avoid disclosure or unauthorized use of Proprietary Information as it
provides to protect its own similar proprietary information but in no event
shall the receiving party fail to use reasonable care under the circumstances to
avoid disclosure or unauthorized use of Proprietary Information. All Proprietary
Information shall be retained by the receiving party in a secure place with
access limited to only such of the receiving party's employees, subcontractors
or agents who need to know such information for purposes of this Contract and to
such third parties as the disclosing party has consented to by prior written
approval. All Proprietary Information, unless otherwise specified in writing (i)
remains the property of the disclosing party, (ii) shall be used by the
receiving party only for the purpose for which it was intended, and (iii) such
Proprietary Information, including all copies of such information, shall be
returned to the disclosing party or destroyed after the receiving party's need
for it has expired or upon request of the disclosing party, and, in any event,
upon termination of this Contract. At the request of the disclosing party, the
receiving party shall furnish a certificate of an officer of the receiving party
certifying that Proprietary Information not returned to disclosing party has
been destroyed. For the purposes hereof, Proprietary Information does not
include information which:

            (i)   is published or is otherwise in the public domain through no
                  fault of the receiving party at the time of any claimed
                  disclosure or unauthorized use by the receiving party;

            (ii)  prior to disclosure pursuant to this Contract is properly
                  within the legitimate possession of the receiving party as
                  evidenced by reasonable documentation to the extent
                  applicable;

            (iii) subsequent to disclosure pursuant to this Contract is lawfully
                  received from a third party having rights in the information
                  without restriction of the third party's right to disseminate
                  the information and without notice of any restriction against

            26.19 Entirety of Contract; No Oral Change. This Contract and the
Exhibits and Schedules referenced herein constitute the entire contract between
the parties with respect to the subject matter hereof, and supersede all
proposals, oral or written, all previous negotiations, and all other
communications between the parties with respect to the subject matter hereof. No
modifications, alterations or waivers of any provisions herein contained shall
be binding on the parties hereto unless evidenced in writing signed by duly
authorized representatives of both parties as set forth in this Contract.

The Vendor is and shall remain an independent contractor in the performance of
this Contract, maintaining complete control of its personnel, workers,
Subcontractors and operations required for performance of the Work. This

otherwise, between the Owner and any Subcontractor, except to establish Owner as
a third party beneficiary of the Vendor's contacts with Subcontractors as
provided herein.

            26.21 Discretion. Notwithstanding anything contained herein to the
contrary, to the extent that various provisions of this Contract call for an
exercise of discretion in making decisions or granting approvals or consents,
the parties shall be required to exercise such discretion, decision or approvals
and in good faith.

            26.22 Non-Recourse. No past, present or future limited or general

be liable by virtue of the direct or indirect ownership interest of such
Operative in the Owner for payments due under this Contract or for the
performance of any obligation, or breach of any representation or warranty made
by the Owner hereunder. The sole recourse of the Vendor for satisfaction of the
obligations of the Owner under this Contract shall be against the Owner and the
Owner's assets and not against any Operative or any assets or property of any
such Operative. In the event that a default occurs in connection with such
obligations, no action shall be brought against any such Operative by virtue of
its direct or indirect ownership interest in the Owner.

            26.23 Improvements, Inventions and Innovations. All rights in any
improvements, inventions, and innovations made solely by the Owner shall vest in
the

improvements, inventions and innovations. All rights in any improvements,
inventions and innovations made by the substantial contribution of both parties
("Joint Information") shall vest jointly in both parties. Joint Information does
not include any underlying information owned by one of the parties prior to
commencement of such joint activities or developed beyond the scope of such
joint activities, including Products and Product information, technical
information or inventions developed prior to the commencement of any joint
activities, developed outside of the scope of such joint activities or developed
solely by either party. The rights of joint ownership to such Joint Information
shall be rights of full non-exclusive worldwide ownership, including rights to
license and transfer. Each party may exploit its rights to the Joint Information
independent of the other and may retain all economic benefits thereof, neither
party shall have any obligation to account to the other for profits derived from
the Joint Information and each party shall have full rights to enforce the Joint
Information intellectual property rights against non-authorized users.

            26.26 References to Certain Sources. Reference to standard
specifications, manuals or codes of any technical society, organization or
association or to the laws or regulations of any Governmental Entity, whether
such reference is specific or by implication, by this Contract, means the latest
standard specification, manual, code, laws or regulations in effect at the time
of such reference, except as may be otherwise specifically agreed to by the
Owner. However, no provision of any reference, standard, specification, manual
or code (whether or not specifically incorporated by reference in this Contract)
shall be effective to change the duties and responsibilities of the Owner or the

this Contract shall require the Owner or the Vendor to violate then existing and
enforceable Applicable Laws.

more third party vendors, contractors and other personnel engaged to provide
work, equipment or services to Owner in connection with or related to this
Contract. Vendor agrees to reasonably communicate and cooperate with such third

In connection with sales of equipment, Ericsson will provide Leap with vendor
financing that will be used for equipment, services and operations needed to
expand its wireless network in various markets across the United States. The
Ericsson agreement is part of Leap's strategy to work with multiple world-class
infrastructure vendors.

communications solutions will be important to Cricket's success as it rolls out
across the United States," said Susan G. Swenson, president of Leap and CEO of
Cricket.

BACKGROUND INFORMATION:

In 1998, Qualcomm deployed a CDMA PCS network for ChaseTel in Chattanooga,
Tennessee. The network, which uses Qualcomm/Ericsson BSS equipment and Alcatel
switches, was commercially launched in the fall of 1998. In January of this
year, Leap Wireless International announced that it would acquire ChaseTel. In
March 1999, Leap's "Cricket" brand of service was launched in Chattanooga. No
products or services are currently sold under the ChaseTel name.

Leap is pursuing a "multi-vendor" strategy and has awarded Lucent an
infrastructure contract to supply equipment for their Cricket networks. Ericsson
will also continue to supply equipment to Leap as they expand their Cricket
networks.

1.   HOW MUCH OF THE EQUIPMENT IS BEING FINANCED BY ERICSSON?

Ericsson is financing * * * percent of the equipment to cover capital and
operational costs associated with the expansion of Cricket's network.

2.   WHEN DOES ERICSSON EXPECT TO OBTAIN BOARD APPROVAL OF THE FINANCING
     AGREEMENT?

Board approval timing depends on Cricket's rollout schedule, which will
determine when equipment is purchased and shipped. Once Cricket presents its
specific rollout plans to Ericsson, we have 30 days to obtain board approval.

3.   WHEN EXACTLY WILL ERICSSON HAVE CDMAONE 1XRTT EQUIPMENT AVAILABLE? DOES
     THAT MEAN THAT ERICSSON WON'T SELL ANY CURRENT GENERATION EQUIPMENT TO
     LEAP?

Ericsson expects to support cdma2000 1XRTT in 2001. Ericsson is undertaking the
normal product development process for our 1XRTT solution, and we'll proceed
with executing trials, demos, prototype equipment, etc over the next year. We'll
keep the market updated as to the specifics of our product availability schedule
as internal milestones are reached.

Ericsson will continue to supply current-generation equipment to Leap Wireless
as per our existing contracts with Pegaso PCS, Chilesat PCS and other operators.

4.   WHERE WILL THE ERICSSON EQUIPMENT BE DEPLOYED IN THE US? WHERE WILL
     LUCENT'S EQUIPMENT BE DEPLOYED?

Cricket's service is currently offered in Tennessee, and Cricket Communications
plans to deploy the service in additional markets across the United States. Leap
has rights to acquire licenses to offer the Cricket service to approximately 24
million potential subscribers (1998 POPs) in more than 50 markets across the
country, including Albuquerque, N.M., Greensboro, N.C., Little Rock, Ark.,
Nashville, Tenn., Salt Lake City, Utah, Spokane, Wash., Tucson, Ariz., Tulsa,
Okla., and Wichita, Kans.

Specific information on Leap's rollout schedule has not been announced. We
expect that some geographical areas will be supplied with Ericsson equipment,
while others will be supplied with Lucent equipment.

5.   IT DOESN'T SOUND LIKE YOU HAVE SPECIFIC EQUIPMENT ORDERS TODAY. WHEN DO YOU
     EXPECT CONCRETE ORDERS AGAINST THIS PURCHASE AGREEMENT?

It is customary in this business to issue master purchase agreements followed by
specific equipment orders. We are currently supplying equipment to several of
Leap's projects, including Chile and Mexico. Specific information on the timing
of Leap's Cricket expansions will have to come from Leap.

6.   DIDN'T ERICSSON, IN EFFECT, ALREADY HAVE A MASTER SUPPLY AGREEMENT WITH
     LEAP BECAUSE OF THE CONTRACTUAL OBLIGATIONS TRANSFERRED FROM QUALCOMM? IS
     THIS REALLY NEW BUSINESS?

Ericsson does have a global agreement with Leap wireless that gives us the right
to supply up to 50% of all of their infrastructure equipment. However, this
agreement has no specific dollar amounts or timeframes attached to it. The $330
million agreements represent new network expansions for Leap, and therefore new
business for Ericsson. In addition, this new agreement is much more specific in
terms of the type of equipment to be supplied.

            QUESTIONS ADAPTED FROM LEAP WIRELESS INTERNATIONAL'S Q&A


1.   IS LEAP PURCHASING LUCENT EQUIPMENT BECAUSE OF SPECIFIC PROBLEMS WITH
     ERICSSON'S EQUIPMENT?

In the past, Leap has indicated that they plan to build a multi-infrastructure
network. The agreement with Lucent simply adds another vendor to Leap's
portfolio of infrastructure equipment.

2.   WHY DID LEAP DECIDE TO CHOOSE A NEW VENDOR NOW?

It is a natural process for a new company such as Leap or Cricket to complete a
vendor selection process when entertaining a major expansion. Recognizing that
Leap has always planned to become a multi-vendor shop, it was essential to
select an additional vendor as they begin to launch in Cricket service in new
markets.

3.   WHAT DOES THIS MEAN FOR LEAP'S RELATIONSHIP WITH QUALCOMM?

This agreement should not have any impact on Leap's relationship with QC.

4.   WHAT DOES THIS MEAN FOR LEAP'S RELATIONSHIP WITH ERICSSON?

Ericsson expects to continue a strong relationship with Leap as they develop and
expand new networks. Leap believes that having two vendors will ultimately mean
better service and pricing for their customers.

5.   WHAT ARE THE TERMS OF ERICSSON'S EXISTING AGREEMENT WITH LEAP? HOW DOES
     THIS TRANSACTION AFFECT THOSE OBLIGATIONS?

Ericsson has the right to supply infrastructure equipment for up to 50% of Leap
needs for any future RFPs under the terms of the separation agreements
(separation agreements between Leap / Qualcomm and Qualcomm / Ericsson).

6.   WILL LUCENT NOW BE YOUR VENDOR IN MEXICO AND CHILE?

This contract covers the domestic markets only. It does not affect the existing
infrastructure in any other markets.

7.   DOES THIS CONTRACT AFFECT THE INFRASTRUCTURE IN OTHER MARKETS?

    Please direct all media inquiries to an appropriate Ericsson spokesperson
        o Michelle French, Senior Public Relations Manager, CDMA Systems
              Phone: +1 858 332 5241, e-mail: [email protected]

         Phone: +46 70 590 05 99, e-mail: [email protected]


It does not affect the existing infrastructure in any other markets.

8.   ARE THERE ANY COMPATIBILITY ISSUES BETWEEN THE TWO VENDORS' EQUIPMENT?

There are no compatibility issues. In fact, Lucent and Ericsson support both
IS-41, which is the interface between switches, and IOS, which is the standard
interface between switches and radio access equipment.

9.   DOES THIS CONTRACT INVOLVE THE EXISTING CHATTANOOGA NETWORK INFRASTRUCTURE
     EQUIPMENT?

Yes, Leap will be putting Lucent equipment into their existing Chattanooga
property, as well as in new markets.

10.  WHY IS LEAP REMOVING ERICSSON'S EQUIPMENT?

The products originally installed in Chattanooga were intended for support of a
traditional mobile wireless network as designed by ChaseTel. Now that Leap has
deployed their Cricket one-rate service plan, the network traffic patterns more
closely resemble landline traffic. Leap plans to redeploy the Ericsson equipment
to be used in more traditional mobile networks.

11.  WHAT WILL HAPPEN TO ALL OF ERICSSON'S EXISTING EQUIPMENT?

The equipment that was originally installed by Qualcomm will be redeployed in
other Leap markets.
