                      specifications are changed, Seller shall timely supply
                      updated information to Buyer, except information Seller
                      reasonably considers to be proprietary or confidential.
                      The information supplied shall include instruction on how
                      to place Products into diagnostic or monitor mode and, if
                      hardware or Software components are necessary, Seller
                      shall supply Buyer, without charge, with a quantity of
                      such components sufficient for Buyer's reasonable
                      requirements. The diagnostic and monitoring information to
                      be provided by Seller shall include specific
                      diagnostic/monitoring testing features on PCS 1900
                      equipment. If unique or proprietary connecting cables are
                      necessary to communicate with the Product when in
                      diagnostic or monitor mode, Seller shall furnish Buyer
                      with a reasonable quantity of such cables, without charge.

               2.2.2  USE OF INFORMATION. Seller hereby grants to Buyer a
                      royalty-free license to use the information described in
                      2.2.1 for Buyer's purposes in constructing, testing,
                      maintaining, using, and operating the Products. Seller
                      shall develop sample software demonstrating interfaces and
                      communications with the Product in diagnostic or monitor
                      mode and Seller shall supply, without charge, copies of
                      same, including sample source code (i.e., sample AT
                      command script), to Buyer for Buyer's use. Buyer shall
                      have the right to incorporate Products in this
                      configuration into its test equipment for testing the
                      Products, including the right to transfer information
                      furnished under this Section 2.2.2 to third parties to
                      develop test equipment for Buyer or to develop such test
                      equipment directly. Seller shall not charge Buyer or any
                      such third party any royalty or other similar charge where
                      the test equipment so developed is used for Buyer's
                      purposes testing the Products.

        2.3    POINT-OF-SALE PACKAGING.

               Seller shall use EAN 328, "3 of 9", or Universal Product Code
               ("UPC") stock control numbering ("SKU") markings or other
               customer-specific bar code markings and human readable format on
               the outside of the point-of-sale package

               for each of the packaging options described below. Seller shall
               provide information to Buyer concerning Seller's bar coding and
               serial number coding for Products, sufficient to permit Buyer to
               properly electronically read Seller's bar coding and to be able
               to monitor and track Products received. Invoices and shipping
               notices shall include electronic copies of serial numbers and
               other information reasonably needed by Buyer to track and control
               inventory.

               Buyer shall select, from time-to-time, its desired packaging
               format from among the options described below, subject to the
               limitations established therein. In the event that Buyer wishes
               to change its desired packaging format, Buyer and Seller shall
               agree upon the lead time necessary to effect such change, Buyer
               shall provide Seller with Notice of its desire to change
               packaging format as soon as possible (but no less than 90 days
               before the format change is desired), and Seller shall use
               reasonable efforts to afford the shortest lead time possible.

               2.3.1  SELLER-LABELED BOX. The Product is packaged and shipped in
                      Seller's standard size rectangular box labeled with
                      Seller's trade name.

               2.3.2  GENERIC BOX. The Product is packaged and shipped in
                      Seller's standard size rectangular box without any labels,
                      in a plain white cardboard format. In the event that any
                      labels, packaging or identifying marks are intended to be
                      attached to, or wrapped around such box, and Buyer uses
                      its transparent packaging, Seller shall design the Product
                      so that the "Novatel Inc." logo will be visible to the End
                      User.

               2.3.3  BULK-SHIP. The Product is shipped in a bulk package,
                      without individual packages for each unit of Product.
                      Buyer has the obligation to arrange for individual unit
                      packaging. In the event that any labels, packaging or
                      identifying marks are attached to, or wrapped around any
                      individual unit packaging, and Buyer uses its transparent
                      packaging, Seller shall design the Product so that the
                      "Novatel Inc." logo will be visible to the End User.

               2.3.4  CUSTOM PACKAGE. The Product is packaged and shipped in
                      Seller's standard size rectangular box with Buyer's
                      artwork and inserts (Commercial Product packaging). Buyer
                      shall provide the necessary artwork in such format and
                      upon such schedules as may be reasonably agreed by the
                      parties. The parties shall agree upon a
                      commercially-reasonable minimum order for such custom
                      packaging. In the event that the cost for producing and
                      shipping such a custom package exceeds Seller's cost to
                      produce and ship its Seller-labeled box, Buyer shall pay
                      that excess amount upon Seller's providing such
                      documentation as Buyer may reasonably require.

               2.3.5  PACKAGE INSERTS. With respect to the packaging performed
                      in sections 2.3.1, 2.3.2, and 2.3.4, Seller shall, without
                      charge to Buyer, insert into each point-of-sale package up
                      to four (4) pieces of Buyer-provided materials such as,
                      but not limited to, promotional materials and Buyer's
                      service provider information. Buyer's promotional
                      materials and information may be different for different
                      models of Products and may differ geographically, which
                      would require different SKU's for each package
                      configuration, but they shall be designed to fit within
                      the point of sale packaging with the Product, without
                      significantly increasing the packaging costs. Seller shall
                      ensure that the proper materials and information are
                      inserted into the corresponding Commercial Product
                      packaging and are delivered to the corresponding
                      geographical regions.

        2.4    CO-BRANDED PRODUCTS.

               2.4.1  CO-BRANDED PRODUCTS. Buyer may wish to receive all or part
                      of its orders in the form of co-branded Products in such
                      form as Buyer shall direct in advance, whereby Buyer's
                      name appears on the Product in addition to Seller's name
                      (such Products being referred to as "Co-Branded
                      Products"). Such Co-Branded Products may be in slightly
                      different form, different color, etc. as may be mutually
                      agreed by Buyer and Seller. Co-Branded Products shall be
                      available to Permitted Purchasers to the extent determined
                      and permitted in writing by Buyer. Seller's logo shall
                      also appear on Co-Branded Products.

                               documentation to Buyer. Notwithstanding anything
                               to the contrary contained in the preceding
                               sentences, the parties may mutually agree upon a
                               commercially reasonable charge for custom
                               manuals, documentation or other similar changes
                               from Seller's standard practices. ***" Seller's
                               charges for packaging of a Co-Branded Product are
                               to be determined consistent with this Section
                               2.4.

        2.5    PRODUCT TEST INSTRUMENTATION. ***, beginning when the first

               device driver software supplied on computer readable media (i.e.
               CD-ROM). In addition, Seller will offer a set of optional
               accessories available *** as identified in Attachment C, which
               shall be updated from time to time as mutually agreed to by the
               parties.

        2.7    UPDATE TO CHANGED STANDARDS. The parties recognize that the PCS
               1900 technology is still undergoing development and that
               Commercial Products may require post-production modification to
               meet changes in the various standards governing such Commercial
               Products.

               2.7.1  Seller agrees to provide to Buyer, ***, all Software
                      necessary to update any Products provided under this
                      Agreement to meet standards changes relevant to the
                      Product, where such standards change becomes effective
                      within *** from the date of delivery of the Product to the
                      End-User and (i) where, without the update, use of the
                      Product would be significantly impaired; or (ii) where the
                      update is necessary to remove a safety risk to users of
                      the Product; or (iii) where the update is necessary in
                      order to continue the safe, efficient and economic
                      operation of Buyer's network; or (iv) where the change is
                      required by operation of federal, state, local, or
                      international law or regulation.

               2.7.2  Further, Seller agrees to provide to Buyer, ***, any

                      this Agreement to meet standards changes relevant to such
                      Products where such standards changes become effective
                      within *** from the date of delivery of the Products to
                      Buyer and where, without the update (i) there would be a
                      material degradation in the operation of significant
                      features of the Products available to End-Users prior to
                      such standards changes and such material degradation
                      occurred with respect to a material number of Products, or
                      (ii) there would be a material degradation in the
                      operation of the network.

               2.7.3  Notwithstanding anything to the contrary contained herein,
                      Seller shall comply with the final order of any court or
                      administrative body with respect to any required
                      modification of any Product.

         2.8   MINIMUM PRODUCT PROCUREMENT.  ***

               2.8.1  RECORDS AND REPORTS. Seller shall maintain records
                      sufficient to accurately determine the actual purchase
                      volume credited to Buyer. Not later than thirty (30) days
                      after the end of each preceding month, Seller shall
                      prepare and provide to Buyer a report of qualifying
                      purchases and credits toward purchases (if appropriate)
                      for the preceding month. The report shall be furnished in
                      both paper and electronic versions. Seller shall certify
                      the accuracy of the report by signature of an appropriate
                      officer of Seller. The report shall be categorized by
                      identity of purchaser

                      Product purchased or credits toward purchases made, and
                      the report shall indicate the unit volume of purchases
                      qualifying for aggregation in each category.

               2.8.2  CONTINUE TO DEVELOP COMPETITIVE PRODUCTS. Buyer's guaranty
                      to purchase the Minimum Purchase Quantity is conditioned
                      upon Seller's ability to continue to supply
                      state-of-the-art Products that are readily accepted by the
                      marketplace.

        2.9    ALLOCATION OF PRODUCTION. In the event that Seller is unable to
               meet its orders for Products as set forth in Purchase Orders that
               have been accepted by the Seller, and without derogation of
               Buyer's other remedies under this Agreement, Seller grants Buyer
               ***. Buyer shall retain this right of first refusal until Buyer
               has met its Minimum Purchase Quantity commitment, or the Minimum
               Purchase Term has expired, whichever is earlier. Buyer's right of
               first refusal shall apply to purchases by Affiliates and
               Authorized Purchasers.

        2.10   EMBEDDED PERMITTED SYSTEM RESTRICTION; PRE-LOADED SIM.

               2.10.1 EMBEDDED PERMITTED SYSTEM RESTRICTION. All Co-Branded
                      Handset Products sold to Permitted Purchasers shall be
                      configured with embedded software so as to function only
                      with a SIM supplied by Buyer or, as provided in Section
                      2.10.2, by Seller, unless otherwise specifically requested
                      by Buyer. Handsets shall be inoperable, except for
                      emergency calls, using a SIM for a network other than
                      Buyer's. Roaming operation with Buyer's network as the
                      subscriber's home system shall be unaffected by this
                      restriction. Such restriction shall be removable only
                      through an input key sequence unique to each individual
                      Handset (i.e., a common un-restriction code for all
                      Handsets of a particular model is not acceptable).
                      Following removal, the Handset shall operate with any SIM.
                      The removal key sequence shall be supplied to Buyer in an
                      electronic database, indexed by the serial number of the
                      Handset or other unique identifier agreed to by Buyer. The
                      removal key sequence shall not be supplied to any other
                      Permitted Purchaser or to the users of Handsets without
                      the written consent of Buyer on a case-by-case basis.

               2.10.2 PRE-LOADED SIM; PRE-PAID SIMS. Buyer intends that all
                      Handsets sold to Permitted Purchasers shall have a SIM
                      configured for Buyer's network pre-installed unless
                      otherwise directed by Buyer. The parties shall negotiate
                      the method of effecting Buyer's intention, recognizing the
                      need for security in the SIM configuration and the need to
                      accomplish installation in a cost-effective fashion. The
                      installation method may involve Buyer supplying configured
                      SIMs to Seller for installation. In those instances where
                      Seller is to install SIMs, the compensation to be

                      Where the parties agree that Seller is to assume
                      responsibility for installing SIMs, information concerning
                      the SIM and International Mobile Equipment Identity
                      ("IMEI"), etc., shall be provided to Buyer in a mutually
                      agreed electronic form. ***. Seller agrees that it will
                      implement reasonable and prudent safeguards to protect all
                      SIMs over which it has custody. In connection therewith,
                      no less frequently than once per calendar quarter, Seller
                      shall provide Buyer with a detail inventory report and
                      proper accounting of SIMs provided to Seller hereunder.

                      Seller agrees promptly to implement pre-paid SIM support
                      in its Handsets upon completion of pre-paid SIM standards.

        2.15   BATTERY RECYCLING. If Seller's Products contain separate
               batteries or batteries replacable by End-Users, Seller shall
               establish a "used battery return program," whereby Buyer and

               recycling used batteries through a nationwide toll-free "800"
               telephone number. Information concerning this program shall be

               Seller under similar circumstances.

3       CUSTOMER REPRESENTATIVE

        3.1    CUSTOMER REPRESENTATIVE. No more than 30 days subsequent to the
               effective date hereof, Seller shall identify a customer
               representative (the "Customer Representative") to whom it shall
               delegate such authority within Seller's organization as is
               necessary for proper discharge of the duties and obligations set
               forth in this Agreement. By illustration and not limitation, the
               Customer Representative shall provide timely information to Buyer
               concerning development, testing and manufacturing schedules, test
               procedures, test execution, shipping and delivery schedules,

               calendar quarter to review Buyer's needs for Products, and
               discuss new Products (such meeting being referred to as an
               "Update Meeting"). At least thirty (30) days prior to each Update
               Meeting, Buyer shall submit to Seller a written, proposed agenda,
               outlining the development issues Buyer would like addressed by
               Seller. Seller shall review such proposed agenda and will provide
               an update to Buyer on any such issue where Seller has provided,
               or is willing to provide, an update to any customer or other
               third party. Further, at each Update Meeting, Seller will provide
               to Buyer an update on the status of the development of any
               features Seller anticipates will be launched within the
               forthcoming two (2) years, provided that Seller has disclosed, or
               is willing to disclose, such information to any customer or other
               third party. Buyer agrees that certain of this information may be
               Confidential Information and shall be treated as such in accord

               Products or new Products intended as replacements for existing
               Products:

               4.3.1  INTERCHANGEABILITY. Where the new or changed Product is
                      intended to be physically interchangeable with an existing
                      Product, such new or changed Product must not adversely
                      affect physical or functional interchangeability with
                      existing Products or performance, unless otherwise agreed
                      in writing by Buyer.

               4.3.3  ADVANCE NOTICE.

                      4.3.3.1  Seller will provide Buyer with advance written
                               notice of any substantial change, modification
                               substitution, or discontinuance, including notice
                               of Seller's intention to change the Product's
                               price as set forth in section 4.3.2. Except where
                               unplanned and immediate market changes make such
                               notice impracticable, the notice shall be given
                               at least ninety (90) days in advance of the
                               effective date of the change, modification or
                               substitution, except that notice of Seller's
                               intention to change the Product's price shall be
                               given at least thirty (30) days in advance of the
                               effective date of the change. Should Seller not
                               have made its final pricing decisions at the date
                               of notice, Seller shall provide Buyer with
                               Seller's estimated prices *** and shall furnish
                               the final price information to Buyer not later
                               than thirty (30) days in advance of the effective
                               date. In the event that Seller has failed to
                               provide the required advance written notice, then
                               Buyer may, at its option, return all unsold
                               inventory of the Products to which the price
                               change applies and receive a credit from Seller

                               returned products. The price for any Product that
                               has not been shipped as of the effective date of
                               the price change shall be deemed to be restated
                               at the new, lower amount.

               4.3.4  ACCESSORY COMPATIBILITY. Where a new Product is
                      introduced, Seller shall ensure that, to the greatest
                      extent reasonably feasible, the new Product is
                      plug-compatible with older Products for accessories. It is
                      not Buyer's intention to limit Seller's ability to
                      introduce smaller or lighter Products through this Section
                      4.3.4. However, Seller shall give due consideration to
                      ensuring compatibility of, among other things, battery
                      chargers, hands-free kits, etc., when introducing new
                      Products.

        4.4    ***.

               ***

               4.4.2  *** either by (i) delivering a check made payable to the
                      order of Buyer or delivering cash to Buyer; or (ii)
                      applying a credit or offset against any outstanding
                      undisputed invoices Buyer has with Seller and delivering a
                      check to Buyer for the remaining amount. In addition to
                      the foregoing, the parties may agree that Seller may apply
                      *** rebate either by (x) delivering to Buyer such quantity
                      of Products as has an aggregate value equal to the ***; or
                      (y) combining any of the first three methods set forth in
                      this Section 4.4.2.

               4.4.3  CERTIFICATION. Buyer may from time to time obtain from
                      Seller, ***, a certification signed by an authorized
                      officer, stating that the price review was performed and
                      whether Buyer or any other Permitted Purchaser is entitled
                      to a rebate or a lower price upon the conclusion of the
                      quarterly price analysis described above. At Buyer's
                      request, Seller shall provide the results and
                      documentation of the review to Buyer's outside independent
                      firm of certified public accountants for verification;
                      provided that the accountants shall not disclose any
                      information related to such review to Buyer, unless Buyer
                      is entitled to lower prices or more favorable terms of
                      sale under this provision and then only such information
                      as may be necessary to request such prices or terms. All
                      information delivered to Buyer shall also be delivered to
                      Seller. In the event that the outside audit determines
                      that a price reduction should have been made but was not
                      made by Seller, Seller shall bear all expenses of the
                      audit. In the event that the outside audit determines that
                      no price reduction should have been made, Buyer shall bear
                      all expenses of the audit.

               sales tax, provided that Buyer has provided Seller with a current
               tax-exempt certificate.

        4.7    SELLER TO HOLD BUYER HARMLESS. Seller agrees to pay, and to hold
               Buyer harmless from and against, any penalty, interest, tax or

               delay or failure of Seller for any reason to pay any tax or file
               any return or information required by law, rule or regulation or
               by this Agreement to be paid or filed by Seller.

               charge. In the event that any payment becomes more than sixty
               (60) days past due, Seller may at its option (i) cease shipment

        twelve (12) month period immediately following the month in which the

        Purchase Quantity has been delivered, but it may be spent at any time in
        the twelve (12) month period immediately following completion of
        delivery of the Minimum Purchase Quantity.


7       TRADEMARKS AND LOGOS

        7.1    LOGOS ON PRODUCTS; ADVANCE CONSENT FOR OTHER LOGOS. At either
               party's reasonable request, the Products shipped under this
               Agreement shall carry that party's designated logo and/or
               labeling as described in Section 2.

        7.2    LIMITED USE OF MARKS. To ensure protection of each party's
               trademarks, trade names, corporate slogans, corporate logo,
               goodwill and product designations, neither party, without the
               express written consent of the other, shall have the right to use
               any such marks, names, slogans or designations of the other, in
               the sales, lease or advertising of any Products or on any Product
               container, component part, business forms, sales, advertising and
               promotional materials or other business supplies or material,
               whether in writing, orally or otherwise.

        7.3    ARTWORK AND REPRODUCTION. To the extent requested by a party and
               in accordance with Sections 2 and 7.1, the other shall provide
               camera-ready artwork of the other's trademarked logo labels. The
               providing party hereby authorizes the receiving party to
               reproduce such trademarked labels to the providing party's
               satisfaction for the sole purpose of affixing such trademarked
               labels to the Products and point-of-sale packaging in accordance
               with the providing party's specifications. Each party represents
               and warrants to the other that it has the right, by way of
               ownership or otherwise, to use such logo and further agrees to
               indemnify and hold the other harmless for any losses, damages or
               other liabilities resulting from the use of the providing party's
               designated logo. The parties will agree upon reasonable

               8.1 FORECAST OF DEMAND. Buyer shall MONTHLY FURNISH SELLER WITH
twelve-month rolling forecasts, showing Buyer's projected purchases month by
month. Buyer shall use its reasonable efforts to make the rolling forecasts
accurate but the rolling forecast does not obligate Buyer to purchase any
specific Products or quantities of Products, subject to the Minimum Purchase
Quantity commitment. Seller shall notify Buyer promptly upon receipt of each
forecast whether Seller can provide Products sufficient to meet the forecast.
Buyer shall provide the first forecast within two business days after complete
execution of this Agreement.

               8.2 PURCHASE ORDERS; ACCEPTANCE; THE MINIMUM PURCHASE QUANTITY.
Buyer shall periodically submit to Seller orders for the purchase of the
Products (each a "Purchase Order") as set forth below. Purchase Orders shall be
governed by the terms and conditions of this Agreement. If a Purchase Order
specifies quantities that do not exceed the forecast, then Seller must accept
that Purchase Order. If a Purchase Order specifies quantities that exceed the
forecast, Seller may at its option accept all of the Purchase Order, but it must
accept that portion or quantity of the Purchase Order specified in the forecast.
If a Purchase Order is within the forecast and Seller can only deliver less, the
difference between the quantity within the forecast and the quantity delivered
shall be applied against Buyer's obligation to purchase the Minimum Purchase
Quantity. In the event that Seller refuses to provide Products in excess of the
quantities set forth in the forecast, then such amounts shall not be applied

                                 provided, however, that each Purchase Order

                                 Specified Delivery Date be sooner than ninety
                                 (90) days after Seller receives the Purchase
                                 Order;

                                 third party delivery points or warehouses [the
                                 "Delivery Location(s)"];

                          (e)    the preferred method of shipping;

                          (f)    the SKU and any other Products packaging or

               8.4. RECEIPTS OF PURCHASE ORDERS. Seller shall provide Buyer with

                                       16

Purchase Order, Seller shall notify Buyer in writing of its acceptance or
rejection of Buyer's Purchase Order including shipment dates. Seller shall also
provide to Buyer notices of actual shipments on each day of shipment. Such
notices shall include the serial numbers of Products being shipped and the
Purchase Order number being filled, SKU, description, quantity shipped and
quantities backordered, the name of the carrier and the carrier's tracking
number, delivery date, and Universal Product Codes ("UPC") related to the
shipment.

               8.5. SIM UNLOCK DATA. Seller shall provide Buyer with all handset
SIM unlock data via electronic or disks within five (5) days of any handset
deliveries. The data format shall follow the GSM NA reference document NAPT 14
(or successor thereto). Upon prior written approval by Buyer, Seller may
implement an alternate means of Seller's choice of providing the SIM unlock
data, provided, however, that if such alternate means requires additional costs
or equipment, this shall be provided to Buyer by Seller free of charge.

               8.6 CHANGES TO DELIVERY LOCATIONS. Changes to the Delivery
Location(s) originally specified on a purchase order must be submitted to Seller
in writing at least fifteen (15) business days prior to the Shipment Date.


               8.7 TEMPORARY HOLD ON DELIVERIES. Buyer shall have the right to
require Seller to hold delivery of up to twenty percent (20%) of any shipment
for a period not to exceed sixty (60) days, where the hold notice is given at
least thirty (30) days in advance of the scheduled shipping date; provided,
however, for all such shipments scheduled to be made during the last calendar
quarter of any year, Seller may, at its option, in lieu of postponing shipment
according to the terms of this Section 8.7, ship the Products as scheduled.
However, if Seller elects not to honor Buyer's hold notice and instead elects to
ship the entire quantity of Product ordered by Buyer, Buyer shall be afforded
sixty (60) days from the date of receipt of the invoice applicable to such
shipped order in which to pay Seller for such shipment. Notwithstanding anything
to the contrary contained in this Section 8.7, if Buyer shall invoke its
privilege to delay delivery of up to twenty percent (20%) and shipment is
delayed as provided herein, the liquidated damages provision of Section 8.10
shall not apply to the late delivery of the re-scheduled shipment(s) and Buyer
expressly acknowledges that Seller may sell to another of Seller's customers any
delayed Handset inventory on hold.

               8.8    CHANGE OF MODEL MIX. Buyer may change the model mix of any
                      shipment of any Purchase Order and Seller shall honor such
                      changes subject to the following:

                      8.8.1.   All such changes must be made in writing.

                      8.8.2.   For changes requested where Products are sought
                               to be substituted for other Products within that
                               same model family, requests for changes made at
                               least ninety (90) days prior to the Specified



                                       17
<PAGE>   24

                             Shipping Date shall be honored, without adjustment
                             to the Specified Shipping Date.

                      8.8.3    For changes requested where (a) Products are
                               sought to be substituted for other Products
                               within that same model family, but the request is
                               made less than ninety (90) prior to the Specified
                               Shipping Date or (b) Products are sought to be
                               substituted for other Products outside the model
                               family, Seller shall, within ten (10) days of
                               receipt of such request, notify Seller whether
                               the requested change is acceptable and/or whether
                               such changes will necessitate a change in the
                               Specified Shipping Date.

        8.9    INABILITY TO MEET A SPECIFIED SHIPPING DATE. Once a Purchase
               Order has been accepted, Seller is expected to deliver the
               Products in such quantities, in such manner and in such time as
               specified in the Purchase Order. As soon as Seller believes that
               it will be unable to meet the Specified Shipping Date, Seller
               shall without delay provide notice to Buyer.

        8.10.  FAILURE TO MEET SPECIFIED SHIPPING DATE. Regardless of whether
               Buyer has been notified of Seller's inability to meet a Specified
               Shipping Date, should Seller fail to ship Products within
               fourteen (14) days of the Specified Shipping Date, Buyer shall
               have the option, which shall not be unreasonably invoked, to
               exercise any one or more of the remedies defined below:

               8.10.1 Cancel the Purchase Order, in whole or in part, with no
                      obligation to pay for the Products specified in the
                      Purchase Order.

               8.10.2 Reschedule the delivery date for all or any part of the
                      late shipment.

               8.10.3 If delivery is not complete by the Specified Shipping
                      Date, then Seller shall be liable for the following late
                      delivery damages: ***

               8.10.4 If Seller fails to make a full delivery within 30 days of
                      the Specified Shipping Date, in addition to the foregoing
                      remedies, ***

        8.11   RIGHT TO COVER. Except as otherwise limited in the manner
               described in this Section 8.11, in addition to any other rights
               that Buyer might have elsewhere in this Agreement, including
               specifically section 8.10, should Seller fail to meet its
               Specified Shipping Date for any Product, at its sole option and
               after providing Seller with written notice no less than thirty
               (30) days prior to seeking alternative supplies, Buyer may seek
               alternative supplies from other manufacturers or distributors.
               However, if within such thirty (30) day period, Seller resolves
               the delivery problems that have caused Buyer to seek such
               alternative supplies, Buyer shall renew purchasing Products from
               Seller on the terms and conditions set forth in this Agreement.

               Should Buyer exercise its option to seek alternative supplies
               after the thirty (30) day period described above, Buyer's Minimum
               Purchase Quantity shall be reduced by the number of units that
               Buyer obtains from its alternative source. The number of units
               that Buyer obtains from its alternative source shall also count
               toward Buyer's ***, as set forth in Section 4.2. For example, in
               the event that Seller fails to meet a Specified Delivery Date for
               *** units, and after 30 days, Buyer exercises its option to
               purchase those *** units from an alternative source, then those
               *** units shall count as purchased in determining when Buyer
               shall begin to recoup the Product Development Fee. If Buyer has
               already begun to ***, then those units shall be eligible for ***
               in accordance with Section 4.2.

               Should Buyer exercise its option to seek alternative supplies
               after the thirty (30) day period described above, Seller shall be
               liable to Buyer for Buyer's increased costs, including
               differences in unit prices, expedited shipping charges and
               related operating costs related acquiring comparable Products
               from an alternative source. Notwithstanding anything to the
               contrary in the immediately preceding sentence, Buyer agrees that
               it shall take reasonable steps to mitigate the level of such
               increased costs and the resultant impact on Buyer's operations.

        8.12   DISCREPANCIES. Buyer shall report to Seller any discrepancies
               concerning the quantity of Products shipped or drop-shipped
               within either five (5) days following delivery or three (3) days
               of discovery of the discrepancy, whichever comes later.

        8.13   MODIFICATIONS TO PURCHASE ORDER. Except to the extent restricted
               by this Agreement, Buyer retains the right to modify or cancel,
               in whole or in part, any Purchase Order prior to complete
               performance thereof by Seller. Any such modification or
               cancellation shall be subject to the provisions set forth below
               and to this Agreement.

               8.13.1 MODIFIED OR CANCELED PURCHASE ORDER. Notwithstanding the
                      foregoing, Buyer may modify or cancel any Purchase Order
                      through notice to Seller. In the event of modification or
                      cancellation of a Purchase Order by Buyer, Seller may be
                      entitled to claim compensation as provided in Section
                      8.13.2.

               8.13.2 CHANGE IN COSTS. If Seller has performed work that is not
                      reusable in fulfilling its obligations under other
                      Purchase Orders issued by Buyer, or that such non-reusable
                      work cannot reasonably be restocked or otherwise used by
                      Seller in fulfillment of its obligations to other
                      customers without increased cost to Seller, then the
                      purchase price to be charged by Seller shall be equitably
                      adjusted. Seller shall inform Buyer of its intention to
                      demand a price increase due to the variation within two
                      (2) weeks after the receipt by the Seller of the modified
                      or canceled Purchase Order. Buyer need not give notice to
                      Seller of Buyer's intention to claim a

                      payment reduction due to any cancellation or reduction in
                      quantity of Products. In such instances, Seller shall
                      reduce appropriately and automatically the invoice amount
                      to reflect the reduced quantity of Product ordered. The
                      determination of any price adjustment shall in no event
                      delay any performance by Seller under this Agreement.

9       QUALITY ASSURANCE

        9.1    ACCEPTANCE TEST PROCEDURE TO BE DEFINED. Buyer and Seller will
               jointly establish the appropriate Acceptance Test Procedures that
               will be added to this Agreement subsequent to the date hereof as
               Attachment E not later than the dates set forth in Attachment B.
               Notwithstanding the preceding sentence, Seller is expected to
               plan other tests, generate test procedures, incorporate Buyer
               input, to the extent Seller believes such input is reasonably
               appropriate, execute tests, report results and rectify test
               failures, before testing a Product for Acceptance.

        9.2    REGULATORY. Seller shall be responsible at its sole cost for
               obtaining any and all approvals and certifications required by
               governing bodies, including, but not limited to, FCC approvals,
               Underwriter's Laboratory approval, etc. Seller is deemed to be an
               expert in obtaining any regulatory approvals and delays in
               obtaining regulatory approval shall not constitute an excusable
               delay, unless such delay is the result of system simulator
               failure or similar problems, or such delay results from an event
               deemed to be Force Majeure, unless Seller can clearly demonstrate
               such, where requests are timely filed. Seller represents and
               warrants that all Products delivered hereunder will have received
               all necessary regulatory approvals. By illustration and not
               limitation of the foregoing, Seller warrants that, upon delivery,
               Products will comply with all FCC rules or other regulations
               including, without limitation, compatibility with disabled or
               handicapped End-Users, including hearing impaired End-Users using
               hearing aids, blind End-Users, etc., applicable as of the date of
               such delivery. Seller also warrants that, to the extent
               applicable to Seller or Buyer, Seller's Products comply with the
               requirements of the Americans With Disabilities Act, 42 U.S.C.
               Section 12101. Seller shall add to its instruction manuals
               information concerning use of Products by disabled or handicapped
               persons. Buyer agrees to provide Seller at Seller's expense with
               reasonable assistance and backup support when so requested by
               Seller and where necessary in obtaining such approvals.

        9.3    ISO 9000 COMPLIANCE; AUDITS. Seller shall endeavor to produce
               Products in accordance with a quality system meeting the
               requirements established in ISO Standard 9001. Seller shall work
               to gain ISO 9001 certification and shall, upon request by Buyer,
               furnish Buyer a copy of Seller's ISO certification plans and
               timetable. Buyer may conduct quality audits of Seller's
               manufacturing facilities up to four times a year, with advance
               notice of five (5) working days.



                                       20
<PAGE>   27

        9.4    MARKET VERIFICATION TEST; COMMERCIAL TEST PROCEDURES. For each
               Prototype model of Product, within five (5) days of the first day
               on which Alpha units are available (as set forth in Attachment
               J), Seller will provide Buyer, at no charge, two (2) such
               Prototypes for testing. Buyer shall test the units according to
               any protocols submitted by Seller and may additionally test the
               units as Buyer deems appropriate. In addition, for each new model
               of Product, within five (5) days of the first (1st) day of Beta
               testing (generally, about thirty (30) days before launch), Seller
               will provide Buyer, at no charge, one hundred (100) units for
               Beta testing in accordance with Seller's protocols. Buyer shall
               conduct all such testing in good faith and shall submit the
               results to Seller within ten (10) days of completion of testing.
               In addition, if Seller so requests, all test units on loan to
               Buyer shall be (i) returned to Seller, or (ii) destroyed by
               Buyer, either at Seller's expense.

        9.5    FIELD TRIALS. Where Buyer and Seller agree to conduct field
               trials using Buyer's network and Prototype Products, should FCC
               type acceptance or other regulatory approval not have been
               granted for the Prototype or Pre-production Products, Seller, at
               its cost and with appropriate support from Buyer in Buyer's
               discretion, shall promptly seek and diligently prosecute, a
               request for expedited approval or an interim waiver to meet
               regulatory requirements. In connection with such field trials, at
               no charge to Seller, Buyer shall provide Seller with a
               commercially reasonable number of SIMs for the purpose of
               conducting such field trials. The SIMs to be provided to Seller
               shall be enabled for use in Buyer's home network and for roaming
               in other networks. The reasonable and customary expenses incurred
               by Seller in performing such tests shall be borne by Seller.

        9.6    SAMPLE TESTING. Seller may at its sole option, but is not
               obligated to, perform adequate testing to assure that shipped
               Products meet Buyer's sample testing criteria established in
               Attachment D. Notwithstanding the foregoing, prior to Seller
               initiating the volume manufacture of Products, Buyer shall have
               the right at its sole option, but is not obligated to, conduct
               sample testing of incoming Products and to reject lots that fail
               to meet the applicable product specifications and quality levels
               set forth in this Agreement and Attachments hereto (including the
               quality levels set forth in Attachment D), and/or US regulatory
               requirements and US law. Buyer shall have the right to conduct
               such testing either at Seller's manufacturing facility ("on-site
               testing") or Buyer's facility ("off-site testing"). Neither
               Buyer's waiver of its right to conduct sample testing nor Buyer's
               conducting sample testing in any way other than as set forth in
               Attachment D shall derogate from or otherwise affect in any way
               Buyer's other rights or remedies under this Agreement, including
               by illustration and not limitation its rights and remedies under
               sections 13, 14, or 17.

               9.6.1  ON-SITE TESTING. Buyer shall have the right to conduct at
                      Seller's site acceptance tests of manufactured Products in
                      such time frames as are



                                       21

                      mutually agreed upon by the parties. Buyer's acceptance
                      tests shall not unreasonably interfere with Seller's
                      normal business operations, and Buyer may not require
                      Seller to provide test equipment for such tests beyond
                      that which Seller normally uses to perform such tests.
                      This testing in no way relieves Seller of any other
                      responsibilities under this Agreement. Seller shall make
                      available such test equipment to Buyer at Seller's
                      location to perform such tests. In the event Buyer
                      requests tests that are not normally performed by Seller,
                      Buyer and Seller shall work together to implement Buyer
                      specific end of process tests. Any increases in cost to
                      Seller to perform such Buyer tests will be negotiated in
                      good faith by both parties prior to Seller initiating such
                      tests.

               9.6.2  OFF-SITE TESTING. Seller acknowledges and agrees that, in
                      addition to the testing described in Section 9.6.1 or in
                      lieu thereof, Buyer shall have the right to conduct
                      off-site sample testing of incoming Products and to reject
                      lots that fail to meet the quality levels set forth in
                      Attachment D. In connection with such off-site testing,
                      Buyer shall bear the cost of any additional test equipment
                      required to perform such test(s); however, Seller shall
                      provide Buyer, without charge, all upgrade(s) to any
                      Seller owned software used in the test equipment so that
                      Buyer is able to test and confirm the quality of the
                      various releases of Products provided hereunder. Buyer
                      shall be solely responsible for any additional testing
                      required to qualify Products for sale in any market other
                      than the U.S. Seller shall perform adequate testing to
                      assure that shipped Products meet Buyer's sample testing
                      criteria set forth in Attachment D.

        9.7    INCOMING INSPECTION. In addition to the sample testing described
               in Section 9.6, Buyer shall have the right to conduct up to one
               hundred percent (100%) inspection of all incoming products
               ("Incoming Inspection"). Any Incoming Inspection shall be
               completed within thirty (30) days of receipt of the Product
               undergoing inspection. The Incoming Inspection shall determine
               completeness of shipment, physical and electrical condition of
               Products, and otherwise verify conformance of the Products with
               the specifications thereof. Buyer shall have the right to reject
               any such shipment as having failed Incoming Inspection. In such
               event, at the Seller's discretion either (i) Buyer may reject the
               shipment and return it to Seller at Seller's expense or (ii)
               Buyer may reject the shipment, and, as soon as commercially
               feasible but no later than seventy-two (72) hours after receiving
               Buyer's notice of rejection, Seller will fly one or more of its
               personnel to the location of such rejected shipment for the
               purpose of examining the same and rectifying the cause for
               Buyer's rejection. Buyer, however, shall not have the right to
               delay payment, where payment to Seller is otherwise due, by
               virtue of Buyer's failure to complete Incoming Inspection within
               thirty (30) days. Buyer's performance of Incoming Inspection,
               however, shall not prevent Buyer from making claims under other
               provisions of this Agreement for defective, misdelivered or
               otherwise incorrect Products.

        9.8    RETURN OF DEFECTIVE PRODUCTS OTHER THAN IN WHOLE SHIPMENTS. With
               respect to Products failing Buyer's acceptance tests, where such
               failures are random in nature and type and are not common
               failures (e.g., a software program bug that affects every unit
               shipped in the same or a similar manner), Seller shall compensate
               Buyer in liquidated damages for Buyer's efforts in identifying
               Defective Products and returning them to Seller for credit
               against Buyer's account. A Product Defect shall include, but not
               be limited to, a damaged, mislabeled or mis-packaged Product, an
               incorrect Product model or improperly operating Product, or a
               Product not in compliance with the specifications as set forth in
               Attachments A-1 through A-3 of this Agreement or such subsequent
               Attachment (a "Defect" or "Defective Product"). The liquidated
               damages shall be in the form of additional like Products shipped
               at Seller's expense, provided without additional charge to Buyer,
               and shall be in addition to any other remedies for Defective
               equipment as provided elsewhere in this Agreement. The liquidated
               damages shall be determined as follows:

               9.8.2  ***

10.     EXTENDED TERM FOR CERTAIN PROVISIONS. Except as may be more specifically

        15, 17, 18, 19, 25, and 32 shall survive the termination of other

               Products to the location specified in the Purchase Order. Seller

               center to Seller's warehouse in San Diego, California. Seller

               Points at the amounts set forth in Attachment C. Delivery of the
               Products shall convey to Buyer all rights and title therein by
               appropriate documents with warranty of title, free and clear of
               all liens and encumbrances. Title to Seller's intellectual
               property, including software, patents, copyrights, trademarks and

13      WARRANTY AND SERVICE REPAIR

        13.1   PRODUCT WARRANTY. Without reducing the scope of warranties
               provided by Seller elsewhere in this Agreement or that may be
               imposed upon Seller at law or in equity, Seller hereby represents
               and warrants to Buyer as follows:

               13.1.1 INTER-OPERABILITY TESTING. Seller shall warrant and
                      certify that it has tested its PCS 1900 Products with PCS
                      1900 network infrastructure manufactured by Northern
                      Telecom, Ericsson, Siemens, Motorola, Nokia and Lucent, to
                      the extent these manufacturers have a functioning PCS 1900
                      test system and are willing to cooperate with Seller in
                      such compatibility testing, and that the results of such
                      tests demonstrate proper inter-operability as of the date
                      of testing. Seller shall periodically inform Buyer of the
                      status of its compatibility testing and shall provide such
                      information to Buyer when Seller introduces a new
                      configuration Product.

               13.1.2 REGULATORY APPROVALS. Seller warrants that all Products
                      have received all necessary regulatory approvals and
                      comply with all applicable federal and state laws, rules,
                      regulations, and codes in existence during the term hereof
                      (including without limitation FCC rules, regulations and
                      requirements),.

               13.1.3 COMPLIANCE. Seller warrants that all Products will work on
                      the full PCS spectrum, Bands A through F, inclusive,
                      except as may be specifically excluded on a
                      product-by-product basis in Buyer's sole discretion.
                      Seller further warrants that the Products comply with all
                      EIA/TIA, GSM, GSM NA, PTCRB, and ETSI standards and all
                      other mutually agreed industry specifications and
                      standards. Seller further warrants that the Products are
                      and will be fully Year 2000 compliant, meaning that the
                      advent of the Year 2000 shall not adversely affect the
                      performance, operation, or networking of any Products,
                      with respect to date or date-dependent data or functions.

               13.1.4 GOOD TITLE. Seller warrants that it has good title to the
                      Products and the right to sell them to Buyer free of any
                      proprietary rights of any other party, security interest,
                      lien or any other encumbrance whatsoever.

               13.1.5 OPERATIONS WARRANTY. Seller warrants that Products
                      furnished by Seller hereunder shall be free from defects
                      in manufacture, material, design, workmanship and title,
                      and shall conform to published specifications at the time
                      of original purchase. This warranty shall not apply to any
                      Product, or part thereof, which (i) has been modified or
                      otherwise altered other than pursuant to Seller's written
                      instructions or written approval, (ii) is in the normal
                      course consumed or depleted in operation or, (iii) is not
                      properly stored, installed, used, maintained or repaired
                      other than by



                                       26

                      Seller-authorized repair, or, (iv) has been subjected to
                      any other type of misuse or detrimental exposure, or has
                      been involved in an accident.

               13.1.6 If a Product fails to meet the foregoing Warranties during
                      the warranty period, Seller shall promptly correct the
                      failure. Any repaired or replacement part furnished
                      hereunder shall be warranted for either the longer of (a)
                      the remainder of the warranty period of the Products in
                      which it is installed or (b) ninety (90) days after the
                      repair or replacement. In the event that Seller is unable
                      to correct the failure through either repair or
                      replacement, Buyer shall return the Product and Seller
                      shall refund the purchase price of the Product.

        13.2   LIMITATION. SUBJECT TO SECTIONS 4, 9, 11, AND 12, THE WARRANTIES
               SET FORTH IN THIS SECTION 13 ARE THE ONLY WARRANTIES, EITHER
               EXPRESS OR IMPLIED, THAT ARE MADE BY SELLER TO BUYER AS TO THE
               PRODUCTS, AND ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, STATUTORY
               OR COMMON LAW, ARE HEREBY EXPRESSLY DISCLAIMED, INCLUDING, BUT
               NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTIBILITY AND
               FITNESS FOR A PARTICULAR PURPOSE.

        13.3   END-USER WARRANTY. In addition, each Product shall come with such
               warranty to the End-User, as Seller shall establish as its
               standard End-User warranty for the Products from time to time,
               the current such standard warranty to the End-User being
               substantially in the form attached hereto as Attachment F. Under
               no circumstances shall the warranty period under the End-User
               warranty be for less than the longer of either (a) one year from
               the purchase of the Product or (b) ninety (90) days from the date
               of repair of the Product.

        13.4   SERVICE REPAIR AND REPLACEMENT. Seller shall maintain one or more
               authorized service centers as may be necessary to provide
               warranty service for the Products. The authorized service centers
               shall be equipped to repair or exchange, at no cost to the owner
               of the Product, defective Products that are within the warranty
               period, as described above. For products requiring repair or
               replacement after expiration of the applicable warranty period,
               Seller's authorized service center shall implement an exchange
               and repaid policy at reasonable rates.

        13.5   EXCHANGE PROGRAM. In order to minimize end-user time without
               Handsets in the event of warranty repairs, Seller shall support a
               Handset exchange program to be administered by PCS Partners or
               other servicer authorized by Seller and selected by Buyer (PCSP).
               Such support shall consist of (a) supplying an appropriate number
               of handsets and standard accessories to PCSP as seed stock
               sufficient to meet warranty replacement needs, and (b) the
               payment of fees to PCSP to cover repairs, refurbishing and one
               way standard ground freight for in-warranty



                                       27
<PAGE>   34

               defective Seller products received from end-users. PCSP shall use
               all in-warranty repaired and refurbished units as replacements
               under the exchange program.

        13.6   CONSISTENT FAILURES. Notwithstanding any disclaimer of warranties
               herein, where delivered Products repeatedly exhibit Defect
               failure rates during the warranty period with regard to any
               particular model of Product (i.e. any lot, batch, or other
               separately distinguishable group of Product sold or delivered to
               the End-user or remaining in inventory has more than ***of the
               same or similar Defect, or *** failure due to cumulative
               Defects), Seller and Buyer shall immediately initiate a joint
               program for appropriate countermeasures and, in addition to any
               other remedy ultimately available to Buyer under this Agreement
               or otherwise, Buyer shall have the option to exercise any of the
               following rights, individually or cumulatively:

               13.6.1 COVER. Buyer may purchase substitute products from another
                      supplier, in which case Seller shall be liable to Buyer
                      for Buyer's increased costs, including increased operating
                      costs, resulting from the substitute products

               13.6.2 TERMINATE FOR CAUSE. Buyer may terminate this Agreement
                      for cause; provided, however, Buyer shall deliver notice
                      to Seller of its intent to terminate this Agreement for
                      cause pursuant to this Section 13.6 and Seller shall be
                      given thirty (30) days in which to completely remedy to
                      Buyer's reasonable satisfaction the problem or problems
                      creating the unacceptable consistent defective failure
                      rate.

               13.6.3 RETURN OF DEFECTIVE PRODUCTS. Upon notice from Buyer of a
                      Product Defect, Seller shall issue a return authorization
                      to Buyer within 48 hours of receipt of notice. A Defective
                      Product may be returned directly by any Permitted
                      Purchaser or by Buyer's distributors or retailers at
                      Seller's expense. Seller shall accept returns even though
                      the Product is no longer in its original point-of-sale
                      packaging. Buyer agrees that each Defective Product is to
                      be returned to Seller without its associated SIM. Buyer's
                      distributors and retailers may return Defective Products
                      for a period starting upon receipt of such Product and
                      ending one (1) year after the last date the particular
                      model of Product has been purchased and received by an
                      End-User. Where Buyer elects to proceed under this Section
                      13.6.3, Seller shall issue an open credit memo to Buyer in
                      the amount of the full invoice purchase price for all
                      returned Products within thirty (30) days of return. Once
                      repaired or replaced, the Products will be delivered with
                      new invoices. This return policy shall continue to apply
                      notwithstanding that Seller has discontinued the model of
                      the Defective Products.

               13.6.4 CANCELLATION OF PURCHASE ORDER. Cancel the Purchase Order,
                      in whole or in part, and return Defective and
                      non-Defective Products to Seller. Should Buyer exercise
                      its option under this section, Buyer's Minimum Purchase
                      Quantity shall be reduced by the number of units returned.
                      That number of units returned shall also count toward
                      Buyer's recoupment of the Product Development Fee, as set
                      forth in Section 4.2.

               13.6.5 RESHIPMENT. Require Seller to ship within 48 hours a
                      comparable non-Defective Product to the location requested
                      by Buyer, at Seller's expense; provided, however, such
                      right shall be exercised by Buyer only for returns of
                      twenty-five (25) or few units of Product.

               13.6.6 DURATION OF RIGHTS. Buyer shall be entitled to exercise
                      its rights under Section 13.6 until such time as Seller
                      establishes to Buyer's reasonable satisfaction that it has
                      cured the consistent failures. Provided, however, that
                      should Buyer have exercised its rights to terminate under
                      Section 13.6.2, Buyer shall be under no obligation to
                      reinstate this Agreement and provided that should Buyer
                      have exercised the remedies identified in Sections 13.6.1,
                      Seller shall be obligated to supply alternative Products
                      and cover Buyer's reasonable expenses, respectively, until
                      Seller has demonstrated, through delivery of Products to
                      Buyer, a period of three (3) consecutive months'
                      compliance with a failure rate of *** in each delivery
                      lot. Where Buyer elects to terminate this Agreement under
                      Section 13.6.2 during the Minimum Purchase Term, Seller
                      shall be liable to Buyer for Buyer's increased costs for
                      the remainder of the Minimum Purchase Term. Where Buyer
                      elects the right of cover under section 13.6.1, for a
                      period of forty-five (45) days following receipt by Seller
                      of notice of Buyer's remedy, Buyer shall provide Seller
                      the opportunity to negotiate the supply contract necessary
                      to effect such cover.

        13.7   SURVIVAL AND TERM. The rights and warranties granted in this
               Section 13 shall survive the term of this Agreement and shall
               remain valid for the periods during which the right or warranty
               is provided as described in this Section 13.

               Agreement upon thirty (30) days prior written notice of
               termination to the other party, unless such breach and any
               intervening breaches have been cured.

        14.2   BANKRUPTCY. Either party may terminate this Agreement by written
               notice in the event that the other party (i) applies for or
               consents to the appointment of, or the

               creditors, (iii) commences a voluntary proceeding under the
               Federal Bankruptcy code or under any other law relating to relief

               Bankruptcy Code or under any other law relating to relief from
               creditors generally, or any application for the appointment of a
               receiver, custodian, trustee, or liquidator of itself or of all
               or a substantial part of its property, or its liquidation,
               reorganization, dissolution, or winding-up.

        14.3   LIMITATION OF LIABILITY.

               14.3.1 EXCEPT FOR SELLER'S LIABILITY UNDER SECTIONS 9, 12, 13,
               15, 17, AND 18, AND EXCEPT FOR SELLER'S GROSSLY NEGLIGENT OR
               INTENTIONALLY WRONGFUL ACTS OR OMISSIONS, THE TOTAL LIABILITY OF
               SELLER, ON ANY AND ALL CLAIMS, WHETHER IN CONTRACT, WARRANTY,
               TORT (INCLUDING NEGLIGENCE) OR OTHERWISE, ARISING OUT OF,
               CONNECTED WITH, OR RESULTING FROM THE PERFORMANCE OR
               NON-PERFORMANCE OF ANY AGREEMENT RESULTING HEREFROM OR FROM THE
               MANUFACTURE, SALE, DELIVERY, RESALE, REPAIR, REPLACEMENT OR USE
               OF THE PRODUCTS OR THE FURNISHING OF ANY SERVICE, SHALL NOT
               EXCEED THE PRICE ALLOCABLE TO THE PRODUCT OR SERVICE WHICH GIVES
               RISE TO THE CLAIM.

               14.3.2 Where a remedy, including a series of optional remedies or
               multiple remedies, is set forth in the Agreement, those remedies
               shall be the sole and exclusive remedies for the breach or event
               for which it is specified, unless such section states that the
               series of remedies are not exclusive of other remedies. Where no
               specific remedy is provided, the non-defaulting party shall have
               the right to recover from the defaulting party only its direct
               damages arising out of that breach or event. NOTWITHSTANDING
               ANYTHING TO THE CONTRARY CONTAINED IN THIS AGREEMENT, IN NO

        14.4   RIGHTS OF PARTIES UPON TERMINATION BY EITHER PARTY. In the event
               of a termination by Buyer or Seller pursuant to the terms hereof,
               the parties shall make an equitable accounting of any sums due
               Seller for partial deliveries, such accounting to be completed
               within sixty (60) days following the effective date of
               termination, with payment by Buyer to be completed within thirty
               (30) days following the completion of such accounting.

               Seller acknowledges and agrees that the Minimum Purchase Quantity
               commitment of Section 2.8 imposed upon Buyer shall be terminated
               in the event of any termination hereunder due to the Seller's
               breach of this Agreement.

         14.5  OTHER GROUNDS FOR TERMINATION. Notwithstanding anything to the
               contrary contained elsewhere in this Agreement, this Agreement
               may be terminated and the obligations of the parties hereunder
               shall be ended under the following circumstances:

                      (a) Buyer and Seller mutually agree in writing to
                      terminate this Agreement;

                      (b) Buyer determines that the development of Products is
                      more than 6 months behind the development schedule set
                      forth in Attachment J; or

                      (c) Buyer determines that key performance requirements
                      (e.g., dataspeeds, etc.) are beyond the deviation or
                      tolerance standards set forth in this Agreement or in any
                      Attachments hereto.


15      CONFIDENTIALITY

        15.1   CONFIDENTIAL INFORMATION DEFINED. During the term of this
               Agreement and thereafter it may be necessary for the parties to
               mutually exchange certain information, data and material of a
               proprietary nature whether relating to marketing, technical,
               financial and other matters. To be treated as confidential
               hereunder ("Confidential Information"), information disclosed in
               writing shall be marked as confidential or proprietary, and the
               disclosing party shall indicate the confidential nature of verbal
               information at the time of disclosure. All Confidential
               Information shall:

               15.1.1 BE HELD IN CONFIDENCE. Be received and retained in the
                      strictest confidence by the parties and will be deemed to
                      be proprietary information of the disclosing party and the
                      recipient(s) of such Confidential Information agree(s)
                      that it (or they) will not disclose it to third parties
                      and further, will treat such information, data or material
                      as proprietary using the same degree of care that it (or
                      they) would normally use in protecting its (or their) own
                      proprietary information.

                      purpose of implementing this Agreement.

        15.2   EXCEPTIONS. The provisions of Section 15.1 above shall not apply
               to any Confidential Information which:

                      (a) Is known by the receiving party prior to the date
                      hereof, and is not subject to or in violation of an
                      obligation of confidentiality;

                      (b) Is or becomes public knowledge other than by default
                      of the receiving party;

                      (c) Is obtained by the receiving party from a bona-fide
                      third party having free right of disposal of such
                      information;

                      (d) Is wholly and independently developed by receiving
                      party without reference to the Confidential Information;
                      or

                      (e) The receiving party is required to disclose pursuant
                      to a valid order of a court or other governmental body or
                      any political subdivision thereof, provided, however, that
                      the recipient of the information shall first have given
                      notice to the disclosing party and made a reasonable
                      effort to obtain a protective order requiring that the
                      information and/or documents so disclosed be used only for
                      the purposes for which the order was issued.

        15.3   SURVIVAL. This Section 15 shall survive any termination of this
               Agreement for a period of two (2) years.


16      FORCE MAJEURE

        16.1   FORCE MAJEURE. Neither of the parties hereto shall be liable for
               any damages or penalty for delay in performance of its
               obligations under this Agreement when such delay is due to acts
               of God, acts of civil or military authority, fires, floods,
               epidemics, war or riots, industry-wide strikes, lockouts or other
               labor disputes, , or any other causes beyond the reasonable
               control of such party. The party so affected shall, upon giving
               prompt written notice to the other party of the delay and the
               cause therefore, be excused from performance to the extent of the
               prevention, restriction or interference; provided, however, that
               the party so affected shall use reasonable efforts to avoid or
               remove such causes of nonperformance and shall continue
               performance hereunder with the utmost dispatch whenever such
               causes are removed. In the event of Force Majeure delays, the
               time for performance shall be extended by mutual agreement of the

               provided above, but in no case shall the extension exceed a
               day-for-day extension based upon the duration of the act of Force
               Majeure.

        16.2   BUYER'S RIGHT TO TERMINATE FOR FORCE MAJEURE. Should Force
               Majeure prevent Seller from timely performing under this
               Agreement, where the Force Majeure delays Seller's performance by
               such time that, in Buyer's reasonable judgment, Buyer has lost
               the benefit of the bargain or where the delay is such that Buyer
               must reasonably look to substitute supplies to protect Buyer's
               position, Buyer has the right to terminate this Agreement,
               notwithstanding the provisions of Section 18.1.

        16.3   SELLER'S RIGHT TO TERMINATE FOR FORCE MAJEURE. Should Force
               Majeure prevent Buyer's performance under this Agreement for a
               period of more than six (6) months, Seller has the right to
               terminate this Agreement, notwithstanding the provisions of
               Section 16.1.


17      PRODUCT LIABILITY INDEMNIFICATION

        Notwithstanding anything to the contrary contained herein, Seller agrees
        to defend, hold harmless and indemnify Buyer, its subsidiaries and
        Affiliates, and its and their officers, agents and employees, from and
        against any damages, claims, demands, liabilities and expenses
        (including reasonable attorneys' fees) that arise out of, or result
        from, the death or bodily injury to, or damage to tangible property of
        any third party resulting (including Seller's employees) from the
        design, manufacture, or use of a Product, whether or not resulting from
        a Defect, produced by Seller or Seller's affiliate. Seller shall pay all
        costs, damages and reasonable attorneys' fees that a court awards as a
        result of such claim provided that: (i) Seller has sole control of the
        defense and related settlement negotiations; (ii) Buyer provides Seller
        with assistance, information and authority reasonably necessary for
        Seller to perform its obligations under this Section 17; and (iii) Buyer
        notifies Seller in writing within thirty (30) days of the discovery of
        the claim. Seller shall not be responsible for any settlement made
        without its consent. Buyer shall not be required to admit any liability
        either to obtain Seller's compliance with the indemnification provisions
        of this Section or for any other reason.


18      INTELLECTUAL PROPERTY INDEMNIFICATION

        18.1   Seller warrants that the Products furnished hereunder shall be
               delivered free of any rightful claim of any third party for
               infringement of any patent, copyright, trademark, trade secret,
               or other intellectual property right. If Buyer notifies Seller
               with thirty (30) days of the receipt of any claim that the
               Products infringes a patent, copyright, trademark, trade secret,
               or other intellectual property right, and gives Seller
               information assistance and exclusive authority to settle and
               defend such claim, Seller at its own expense shall indemnify,
               defend, and hold harmless



                                       33
<PAGE>   40

               Buyer, or may settle, any suit or proceeding against Buyer so far
               as based on a claimed infringement which breaches this warranty.
               If, in any such suit arising from such claim, the continued use
               of the Products for the purpose intended is enjoined by any court
               of competent jurisdiction, Seller shall, at its expense and
               option, either: (i) procure for Buyer the right to continue using
               the Products, or (ii) modify the Products so that they become
               non-infringing, or (iii) replace the Products or portions thereof
               so that they become non-infringing, or (iv) if none of (i), (ii),
               or (iii) can be accomplished within a reasonable period, accept
               the return of the Products and refund the purchase price. The
               foregoing states the entire liability of Seller for patent,
               copyright, trademark, trade secret or other intellectual property
               right infringement by the Products and is subject to any
               limitation of total liability set forth in this Contract. Buyer
               shall not be required to admit any liability either to obtain
               Seller's compliance with the indemnification provisions of this
               Section or for any other reason.

        18.2   The preceding subsection 18.1 shall not apply to: (i) any portion
               of the Products that is manufactured to Buyer's design, provided
               that the claim of infringement arose out of Buyer's design or
               (ii) the use of the Products for a purpose not intended or in
               conjunction with any other apparatus or material not supplied by
               Seller to the extent that such conjoined use causes the alleged
               infringement. As to any portion of the Products or use described
               in the preceding sentence, Seller assumes no liability whatsoever
               for patent, copyright, trademark, trade secrets, or intellectual
               property rights infringement.

        18.3   Seller will not be responsible for any compromise or settlement
               made without its written consent.

19      DISPUTE RESOLUTION

        19.1   INTERNAL ESCALATION. In the event that a dispute arises over the
               interpretation or application of any provision of this Agreement
               or the grounds for termination hereof, any party may request that
               the parties meet within ten (10) days of such request and seek to
               resolve the dispute by negotiation of the appropriate officers of
               each party, with the request for resolution being passed to each
               officer at the next higher level of authority, in turn. Such
               meetings shall be attended by individuals with decision-making
               authority, to attempt in good faith to negotiate a resolution of
               the dispute prior to pursuing other available remedies. If,
               within ten (10) days after the first such meeting, the parties
               have not succeeded in negotiating a resolution of the dispute, or
               if it has not been possible to schedule a meeting within ten (10)
               days following request thereof by a party, a party may request
               that such dispute be mediated in accordance with Subsection 19.2.
               Notwithstanding anything to the contrary contained in the
               foregoing, any disputes with respect to intellectual property
               rights shall be submitted to the courts and not



                                       34
<PAGE>   41

               subject to the provisions of Subsection 19.2, unless otherwise
               agreed by both Buyer and Seller.

        19.2   MEDIATION. If the attempts to resolve a dispute described in
               Subsection 19.1 fail, then such dispute will be mediated by a
               mutually acceptable mediator to be chosen by Seller and Buyer
               within twenty (20) days after written notice by either party
               demanding mediation. A party may not unreasonably withhold
               consent to the selection of a mediator, and Seller and Buyer
               shall share the costs of mediation equally. Each party shall pay
               its own attorneys' fees. By mutual agreement, however, Seller and
               Buyer may postpone mediation until each has completed some
               specified but limited discovery regarding the dispute. The
               parties may also agree to replace mediation with some other form
               of alternate dispute resolution, such as neutral fact-finding or
               mini-trial.

        19.3   ARBITRATION OF DISPUTES. Any controversy or claim arising out of
               or relating to this Agreement for the breach hereof which cannot
               be settled by the parties pursuant to Section 19.1 and 19.2,
               shall be settled by arbitration in accordance with the commercial
               arbitration rules of the American Arbitration Association as set
               forth herein.

               19.3.1 SELECTION OF ARBITRATORS. Each party may select one
                      arbitrator. Selection shall be completed within ten (10)
                      days of the receipt of a demand for arbitration. If either
                      party fails to select an arbitrator within such ten (10)
                      day period, the one selected shall act as sole arbitrator.
                      If two (2) arbitrators have been selected, the two
                      arbitrators selected shall select a third within fifteen
                      (15) days after their selection. If they fail to do so,
                      the third arbitrator shall be selected by the American
                      Arbitration Association. The arbitrators shall set a date
                      of hearing no later than sixty (60) days from the date all
                      arbitrators have been selected and shall enter a decision
                      within thirty (30) days at the end of the proceeding

               19.3.2 LANGUAGE. All proceedings shall be conducted in the
                      English language.

               19.3.3 LOCATION. The arbitration shall take place at a location
                      to be agreed upon by the parties. If the parties are
                      unable to agree, the arbitration shall be in Bellevue, or
                      Seattle, Washington, as designated by Buyer.

               19.3.4 FRCP TO APPLY. In any such arbitration proceeding the
                      arbitrators shall adopt and apply the provisions of the
                      Federal Rules of Civil Procedure relating to discovery so
                      that each party shall allow and may obtain discovery of
                      any matter not privileged which is relevant to the subject
                      matter involved in the arbitration to the same extent as
                      if such arbitration were a civil action pending in a
                      United States District Court; provided, however, that each
                      party shall be entitled to no more than four (4)



                                       35
<PAGE>   42

                      depositions upon oral examination of no more than one (1)
                      day in length each.

               19.3.5 FINAL AWARD. The award of any arbitration shall be final,
                      conclusive and binding on the parties hereto.

               19.3.6 REMEDY. The arbitrators may award any legal or equitable
                      remedy. The arbitration award shall include an award of
                      reasonable attorney's fees, in the amount of such fees, to
                      the prevailing party. Judgment upon any arbitration award
                      may be entered and enforced in any court of competent
                      jurisdiction.

               19.3.7 INJUNCTIVE RELIEF. Either party to an arbitration
                      hereunder may bring an action for injunctive relief
                      against the other party if such action is necessary to
                      preserve jurisdiction of the arbitrators or to maintain
                      status quo pending the arbitrators' decision. Any such
                      action called pursuant to this paragraph shall be
                      discontinued upon assumption of jurisdiction by the
                      arbitrators and their opportunity to consider the request
                      for equitable relief pending final decision in the
                      arbitration.

        19.4   CONTINUE TO PERFORM. The parties shall continue to perform all
               obligations under the Agreement pending the above-described
               dispute resolution proceedings, subject to full reservation of
               rights at law or under this Agreement.

        19.5   CHOICE OF LAW. THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN
               ACCORDANCE WITH AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF
               WASHINGTON, WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF
               LAW THEREOF.


20      NON-EXCLUSIVE AGREEMENT

        This Agreement is a nonexclusive agreement. Buyer expressly reserves the
        right to contract with others for any of the goods or services it may
        require, including those that may duplicate Products.


21      INSURANCE

        21.1   SELLER TO MAINTAIN. Seller shall maintain and keep in force all
               risk insurance, in form and substance and with insurers
               reasonably satisfactory to Buyer, covering all Products delivered
               to Buyer the risk of loss to which has not passed to Buyer, and
               shall furnish Buyer with proof that such insurance has been
               obtained and is in force.

<PAGE>   43

        21.2   LEVEL OF INSURANCE. Seller shall at all times while performing
               services on Buyer's premises carry insurance with limits not less
               than the limits described as follows:

                      (a) Employer's General Liability: Limits ***.

                      (b) Comprehensive General Public Liability: *** single
                      limit bodily injury and property damage combined; such
                      coverage shall include a broad form liability rider,
                      completed operations coverage rider and contractual
                      liability rider.

                      (c) An umbrella policy: with *** single limit bodily
                      injury and property damage combined.

                      (d) Workmen's Compensation: maintained at least at the
                      level required by statute in the states in which Seller is
                      to perform work under this Agreement.

        21.3   CERTIFICATES OF INSURANCE. Seller shall provide Buyer with
               certificates of insurance (i) evidencing the insurance to be
               carried under this Article 21, naming the Buyer as an additional
               insured and (ii) including provisions that such insurance policy
               shall not be subject to cancellation, expiration or reduction
               without thirty (30) days written notice to Buyer.

        21.4   NO WAIVER. Notwithstanding the requirements as to insurance to be
               carried, the insolvency, bankruptcy or failure of any insurance
               company carrying insurance for either party, or failure of any
               such insurance company to pay claims accruing, shall not be held
               to waive any of the provisions of this Agreement or relieve
               either party from any obligations under this Agreement.

22      ASSIGNMENT

        22.1   CONSENT REQUIRED. Except as otherwise expressly provided in this
               Agreement, no party shall have the right to assign its rights or
               delegate its duties under this Agreement or any Purchase Order
               hereunder, without the prior written consent of the other party
               hereto, which consent shall not be unreasonably withheld.
               Notwithstanding the foregoing, Buyer may assign its rights and
               obligations hereunder to (1) any corporation resulting from any
               merger or other reorganization to which Buyer is a party, (2) any

               assets or business existing at such time, or (3) any entity which
               controls, is controlled by, or under common control with Buyer.

        waiver by the non-defaulting party of any other default. Failure of a
        party to exercise a right or remedy shall not be deemed a waiver of that
        right or remedy.


27      AMENDMENTS

        No provisions of this Agreement or any Purchase Order shall be deemed
        waived, amended or modified by a party, unless such waiver, amendment or

        of the party against whom it is sought to enforce such waiver, amendment
        or modification.


28      ORDER OF PRECEDENCE

        During the Term, Buyer's purchase of Products from Seller shall be
        deemed to be purchased under the terms and conditions of this Agreement.
        The terms and conditions of Buyer's Purchase Order, Seller's
        acknowledgments, invoices or any other writings by either party which
        differ from the terms hereunder shall not be effective unless
        specifically accepted in writing by amendment to this Agreement made
        separate and apart from said terms and conditions and signed by all of
        the parties to this Agreement. In the event of any conflict or
        inconsistency among the provisions of this Agreement and the



                                       39

        and thereafter to the Attachments.

        purposes only and shall not affect in any way the meaning or
        interpretation of this Agreement.


30      SEVERABILITY

        If any provision or any part of a provision of this Agreement shall be
        invalid or unenforceable, such invalidity or unenforceability shall not
        invalidate or render unenforceable the entire Agreement, but rather the
        entire provision or the Agreement shall be construed as if not
        containing the particular invalid or unenforceable provision or
        provisions, and the rights and obligations of the parties shall be
        construed and enforced accordingly, provided, that the deletion of such
        provision does not change the intent of the Agreement.


31      SURVIVAL

        The provisions contained in this Agreement that by their sense and
        context are intended to survive the cancellation or termination of this
        Agreement or any Purchase Order hereunder shall survive such
        Cancellation and termination.

        Except as specifically provided in Section 2 hereof, no licenses,
        express or implied, under any patents, copyrights, trademarks or trade
        secrets are granted by Buyer or Seller to the other hereunder.


33      PARTY RELATIONSHIP

        It is expressly understood that the parties intend by this Agreement to
        establish the relationship of independent contractors. No party shall
        have any authority to create or assume in the name of or on behalf of
        the other party any obligation, express or implied, nor to act or to

</TABLE>

Notwithstanding anything to the contrary set forth herein below, three Minor
Defects (as defined in the Defect Categorization for AQL Testing table set forth
herein below) of Handset Products shall also be deemed to constitute a Major
Defect and contribute to the acceptance or rejection of a lot as provided in the
table, rounded downward (i.e., five (5) Minor Defects should be counted as one
(1) Major Defect, while six (6) Minor Defects shall be counted as two (2) Major
Defects).

Major and Minor Defects are determined on a per-Product basis (i.e., a single
unit of Product with two (2) Major Defects is counted only as a single Major
Defect for the purpose of acceptance or rejection of a lot).

Should Buyer reject a lot based upon sample testing in accordance with this
Attachment E, Seller shall have the option to perform 100% testing of the lot,
at Seller's sole expense, at Buyer's premises or elsewhere with Buyer having the
right of observation of the tests and may re-submit the lot (less any defective
units) to Buyer. Seller agrees that Buyer may then re-sample test the
re-submitted lot, and Buyer may accept or reject such lot based on the testing
criteria set forth above.

Seller shall provide Buyer with Product specifications, including pass/fail
limits on parameters.

ATTACHMENT I RETURN POLICY


Recognizing that product sold to our customers is done so in good faith, the
return of stock is considered contrary to the original purchase terms. However,
at your request, Seller will consider the return of customer's inventory under
certain market conditions. Seller will only consider credit returns if our
customer has demonstrated active promotion and proper positioning of our
product.

This agreement is necessitated by the cost prohibitive nature of stock returns
and covers the blanket guidelines for processing a return. As a partner with
Seller interested in growing our relationship and respective businesses,
customers are asked to share the cost of this burden.

Note that each request for return must be specifically agreed to by the Seller
customer representative and Seller management. To obtain approval for a specific
restock return for credit, a customer signed agreement in accordance with the
following return guidelines is required:

        The product must be in current production and directly purchased by
        Buyer within the last 90 days. If product is determined to been
        purchased from other suppliers, product will be returned to customer.

        The product must be in new, immediate resoluble condition including
        original packaging and master cartons.

        ***

        A return authorization will be provided by your sales representative. It
        will be valid for 30 days from issuance.

        Stock is to be returned to the Seller San Diego, California, facility.

        No custom products are returnable under this policy.

        Buyer shall pay freight on returns.

Credit will be provided to customer's account within thirty (30) days.
