         Seller specified in Section 12 hereof. Seller's Designated
         Representative (or his agents) shall, with a representative of

         configuration, Products, scope of Services and any other ancillary

         then develop an equipment list and price sheet for the Products and
         Services required for each Site using the prices set forth in Exhibit A
         (the "Quotation").

     b.  Following receipt of the Quotation, Customer shall order Products and
         Services by submitting a Purchase Order to which the Quotation shall be
         attached and made a part thereof. The Purchase Order shall also include
         the desired delivery date and whether partial deliveries are
         acceptable. Purchase Orders should be submitted by Customer to Seller
         at least 90 days prior to date of delivery for such Products and
         Services. Upon receipt of the Purchase Order, Seller shall have five
         (5) business days to accept or reject the Purchase Order in writing.

     c.  In the event that the Customer submits a Purchase Order without a
         Quotation, such Purchase Order shall be subject to completion of a Site
         Survey by Seller. If following the completion of the Site Survey,

         forth in the Purchase Order must be changed, Seller shall, within ten
         (10) days of completion of the Site Survey, notify Customer with a
         written proposal for changes to the Purchase Order. Upon receipt,
         Customer shall have five (5) business days to accept or reject the
         written proposal for changes. If accepted, Customer shall execute a
         written Change Order to reflect the required changes identified by the
         Site Survey. If Customer rejects the Change Order Customer may cancel
         the Purchase Order subject to Section 3(d) below.

     d.  Customer may cancel or delay delivery of a Product contained in any
         Purchase or Change Order prior to Seller's shipment of the Product
         subject to the terms herein. Any such cancellation or delay must be
         made by written notification. If Customer directs such cancellation or
         delay with less than 30 days written notice from the delivery date
         specified in Purchase Order or Change Order, Customer shall pay to
         Seller any reasonable costs associated with such cancellation or delay
         provided, however, that any such costs shall not exceed in the
         aggregate ten percent (10%) of the Purchase Price of each canceled or
         delayed Product. Customer shall not be obligated to pay any such costs
         if Customer timely exercises its cancellation rights under section 3(c)
         hereof.

     e.  Within thirty days following execution of this Agreement, Customer
         shall give Seller a non binding forecast of Customer's estimated
         requirements for the Products and Services for the forthcoming twelve
         (12) months such forecast shall be updated by Customer on a monthly
         basis.

4.   SHIPPING, TITLE, RISK OF LOSS

     a.  Unless otherwise instructed by Customer, and subject to Section 3,

         Purchase Order and render invoices in accordance with Section 5 below.

         charges, except as noted in Section 4(b) below.

         sold by Seller to Customer hereunder shall pass to Customer upon
         Performance Acceptance. For all Follow-on Orders title to and risk of
         loss or damage to Products sold by Seller to Customer hereunder shall

         the Software License attached as Exhibit E hereto.

<PAGE>

         2.  In the event that Performance Acceptance for the Products in the
             Initial Order does not occur and Seller has indicated in writing
             that it will no longer pursue Performance Acceptance, Customer
             shall have the option of either (i) completing the purchase of the
             Products in which case Seller shall render an invoice for the
             balance due or (ii) returning the Products to the Seller. If
             Customer chooses to return the Products to Seller, Seller shall de-
             install such Products at Seller's expense and repair any damage to
             or reverse any modifications to the Customer's equipment at the
             Site caused by Seller during installation of the Products and
             during the Performance Evaluation Period. Seller shall arrange for
             and pay the costs of shipping and assumes the risk of loss and
             damage to Products during shipment of the Products back to its
             headquarters in Redmond, Washington.

     b.  For Follow-on Orders for Products, to be installed by Seller, Seller
         shall render invoices as follows: (i) [**] of the Purchase Price of
         each Product upon shipment of a Product to Customer, and (ii) [**] of
         the Purchase Price of each Product and one hundred percent (100%) of
         any associated Services promptly following the Commissioning of a
         Product. For Follow-on Orders, to be installed by Customer, Seller
         shall invoice Customer for one hundred percent (100%) of the Purchase
         Price of each Product upon shipment of Product to Customer.

     c.  For Follow-on-Orders for Services only, Seller shall render invoices
         for 100% of the Purchase Price upon the completion of the Services, or
         on alternative milestones based upon mutual agreement of the parties.

     d.  All invoices shall be computed on the basis of the prices set forth
         in Exhibit A (including any applicable discounts) and shall identify
         and show separately quantities of Products, type of Services, total
         amounts for each item, shipping charges, insurance charges, applicable
         sales or use taxes and total amount due. Customer shall promptly pay
         Seller the amount due within thirty (30) days of the date of receipt of
         the invoice, except for the Initial Order only which shall be due
         ninety (90) days of the date of receipt of the invoice. Customer shall
         pay a late fee at the rate of one and one-half percent (1.5%) of the
         amount due for each month or portion thereof that the amount remains
         unpaid.

     e.  Excluding income, business and licensing taxes, Customer shall be
         responsible for the payment of all sales, use and any other taxes
         applicable specifically to the sale of the Products and Services
         provided by the Seller pursuant to this Agreement. When Seller is
         required by law to collect such taxes, 100% thereof will be added to
         invoices as separately stated charges and paid by Customer in
         accordance with this section.

     f.  If Customer disputes any invoices rendered or amount paid, Customer
         will so notify Seller, and the parties will use their reasonable
         efforts to resolve such

         dispute expeditiously. Provided that Customer so notifies Seller of a
         disputed invoice and there is a good faith basis for such dispute, the
         time for paying the portion of the invoice in dispute shall be extended
         by a period of time equal to the time between Seller's receipt of such
         notice from Customer and the resolution of such dispute.

6.   WARRANTY

     a.  Seller warrants, for the Initial Order, for a period of [***] from the

         further represents that, in connection with providing Calendar-Related
         data to and accepting Calendar-Related data from other automated,

         earlier termination of this Agreement. For purposes of this section,
         "Calendar-Related" refers to date values based on the Gregorian
         calendar, as defined in Encyclopedia Britannica, 15th edition, 1982,
         page 602, and to all uses in any manner of those date values, including
         without limitation manipulations, calculations, conversions,
         comparisons, and presentations; "Date Data" means any Calendar-Related
         data value in the inclusive range January 1, 1900 through December 31,
         2094, which the Product uses in any manner; and "System Date" means any
         Calendar-Related data value in the inclusive range January 1, 1985

        settlement negotiations, and (iii) Customer gives Seller information and
        assistance for the defense (Customer will be reimbursed for reasonable
        costs and expenses incurred in rendering such assistance, against
        receipt of invoices therefor). Subject to the conditions and limitations
        of liability stated in this Agreement, Seller shall indemnify and hold
        harmless Customer from all payments, which by final judgments in such
        claims, may be assessed against Customer on account of such alleged
        infringement and shall pay resulting settlements, costs and damages
        finally awarded against Customer by a court of law, arbitration or other
        adjudication of the claim.

     b. Customer agrees that if the Products or Software become, or in Seller's
        opinion are likely to become, the subject of such a claim, Customer will
        permit Seller, at Seller's option and expense, either to procure the
        right for Customer to continue using such Products or Software or to
        replace or modify same so that they become non-infringing as long as
        they continue to conform in all material respects to the specifications
        contained in this Agreement and Exhibits, and, if neither of the
        foregoing alternatives is available on terms which are acceptable to
        Seller, Customer shall at the written request of Seller, return the
        infringing or potentially infringing Products or Software and all the
        rights thereto at Seller's expense. Customer shall receive a refund of
        the prorated undepreciated portion of the Purchase Price actually paid
        by Customer to Seller for the returned portion of the Products. The
        Purchase Price shall be straight-line depreciated over a five (5) year
        period.

     c. Seller shall have no obligation to Customer with respect to any claim of
        patent or copyright infringement which is based upon (i) adherence to
        specifications, designs or instructions furnished by Customer, (ii) the
        combination, operation or use of any Products supplied hereunder with
        products, software or data with which the Products are not intended to
        be used or for which the Products are not designed, (iii) the alteration
        of the Products or modification of any Software made by any party other
        than Seller; or (iv) the Customer's use of a superseded or altered
        release of some or all of the Software if infringement would have been
        avoided by the use of a subsequent unaltered release of the Software
        that is provided to the Customer.

9.   INDEMNIFICATION

          Seller shall indemnify Customer, its employees and directors, and each
     of them, against any loss, damage, claim, or liability, arising out of, as
     a result of, or in connection with the use of the Product in accordance
     with this Agreement or the acts or omissions, negligent or otherwise, of
     Seller in the performance of this Agreement, or a contractor or an agent of
     Seller or an employee of anyone of them, except where such loss, damage,
     claim, or liability arises from the sole negligence or willful misconduct
     of Customer, agents or its employees. Seller shall, at its own expense,
     defend any suit asserting a claim for any loss, damage or liability
     specified above, and Seller shall pay any costs, expenses and attorneys'
     fees that may be incurred by Customer in connection with any such claim or
     suit or in enforcing the indemnity granted above, provided that Seller (i)
     is given prompt notice of any such claim or suit and (ii) full opportunity
     to assume control of the defense or settlement. Customer shall, at its
     discretion, have the right to reasonably participate in the defense and
     settlement of any claim asserted against Customer, including, but not
     limited to, choice of counsel and any settlement, but Seller shall have
     final authority to choose counsel and determine whether or not to settle a
     claim. Neither Seller nor Customer shall not be liable to the other for
     indirect or consequential damages, including but not limited to lost
     profits or revenue.

10.  TERM AND TERMINATION

          The term of this Agreement shall be three (3) years from the Effective
     Date. If either party is in material default of any of its obligations
     under this Agreement and such default continues for thirty (30) days after
     written notice thereof by the party not in default, the nondefaulting party
     may cancel this Agreement. In addition, a party may cancel this Agreement
     if a petition in bankruptcy or under any insolvency law is filed by or
     against the other party and is not dismissed within sixty (60) days of the
     commencement thereof.

11.  ASSIGNMENT

        substantially all of the assets, business or stock of Seller, whether by
        sale, merger or otherwise.

     b. Customer shall not (i) assign, sublicense or otherwise transfer the
        Software License set forth in Exhibit E, to any third party other than
        an Affiliate without the prior consent of the Seller, (ii) purchase a
        Product solely for the purpose of reselling or distributing it to
        another party, (iii) transport, relocate, or otherwise transfer the
        Products or the Software outside the United States, or (iv) permit its
        directors, officers, employees, agents or any other third person to
        modify, copy, decompile, disassemble or reverse engineer the Products or
        the Software.

     c. Subject to the provisions of paragraphs a, and b above, this Agreement
        shall inure to the benefit of and be binding upon the respective
        successors and assigns, if any, of the parties hereto.

13.  COMPLIANCE WITH LAWS

          Seller shall comply with all applicable federal, state and local laws,
     regulations and codes, including the procurement of permits and licenses
     when needed, in the performance of this Agreement.

14.  FORCE MAJEURE

          Except for payment of moneys due, neither party shall be liable for
     delays in delivery or performance or for failure to manufacture, deliver or
     perform resulting from acts beyond the reasonable control of the party
     responsible for performance. Such acts shall include, but not be limited to
     (a) acts of God, acts of a public enemy, acts or failures to act by the
     other party, acts of civil or military authority, governmental priorities,
     strikes or other labor disturbances, hurricanes, earthquakes, fires,
     floods, epidemics, embargoes, war, riots, and loss or damage to goods in
     transit; or (b) inability to obtain necessary products, components,
     services or facilities on account of causes beyond the reasonable control
     of the delayed party or its suppliers. In the event of any such delay, the
     date(s) of delivery or performance shall be extended for as many days are
     reasonably required due to the delay. If

                                      12
<PAGE>

     such delay continues for 45 days, either party may terminate the Purchase
     Order affected by the event by providing written notice.

15.  GOVERNING LAW; DISPUTE RESOLUTION

     a. This Agreement and each Purchase Order shall be construed in accordance
        with the internal laws of the State of California, without regard to its
        choice of law provisions.

     b. Any and all disputes arising between the parties shall be resolved in
        the following order: (i) by good faith negotiation between
        representatives of Customer and Seller who have authority to fully and
        finally resolve the dispute to commence within ten (10) days of the
        request of either party; (ii) in the event that the parties have not
        succeeded in negotiating a resolution of the dispute within ten (10)
        days after the first meeting, then the dispute will be resolved by
        nonbinding mediation to be held in a mutually agreed location in the
        United States, using a mutually agreed upon non-affiliated neutral party
        having experience with or knowledge in the wireless communications
        equipment industry to be chosen within twenty (20) days after written
        notice by either party demanding mediation (the costs therefor to be
        shared equally); and (iii) if within sixty (60) days of the initial
        demand for mediation by the parties, the dispute cannot be resolved by
        mediation, then a party may institute litigation in a court having
        subject matter jurisdiction, and the parties expressly consent and
        submit themselves to the personal jurisdiction of such court. If
        compliance with this section would result in expiration of any statute
        of limitations for the filing of a court action, the statute of
        limitations shall be tolled for the period of time required to comply
        with this section.

16.  CONFIDENTIALITY

     a. During the term of this Agreement and thereafter it may be necessary for
        Seller and Customer to mutually exchange certain information, data and
        proprietary material relating to marketing, sales, technical, financial
        and other matters involving the Products, this Agreement or the
        relationship between the Seller and Customer. In order 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 oral
        information at the time of disclosure and provide written confirmation
        thereof within fifteen (15) days following such disclosure. All
        Confidential Information shall:

        1. 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) agree(s) that it 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; and

                                      13
<PAGE>

        2. Be used by the parties hereto solely for the purpose of implementing
           this Agreement.

     b. This provision shall not apply to any Confidential Information which:
        (i) is known by the receiving party prior to the date of disclosure by
        the disclosing party, and is not subject to or in violation of an
        obligation of confidentiality; (ii) is or become public knowledge other
        than by default of the receiving party; (iii) is obtained by the
        receiving party from a bona-fide third party having free right of
        disposal of such information; (iv) is wholly and independently developed
        by receiving party without reference to the Confidential Information; or
        (v) the receiving party is required to disclose pursuant to any law,
        regulation or 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.

     c. Subject to the foregoing, this Agreement shall also be treated
        confidentially by all parties hereto.

     d. This section shall survive any termination of the Agreement for a period
        of three (3) years.

17.  GENERAL PROVISIONS

     a. Seller and Customer may issue a joint press release concerning the
        execution of this Agreement. Such press release shall be subject to
        prior review and written approval by both parties, not to be
        unreasonably withheld.

     b. Any waiver by any party of any breach or failure to comply with any
        provision of this Agreement by the other party must be in writing and
        shall not be construed as, or constitute, a continuing waiver or such
        provision, or a waiver of any other provision of this Agreement.

     c. If any of the provisions 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
        Agreement shall be construed as if not containing the particular invalid
        or unenforceable provisions, and the rights and obligations of Seller
        and Customer shall be construed and enforced accordingly.

     d. This Agreement, including all Exhibits which are attached to and hereby
        incorporated into this Agreement, shall constitute the entire agreement
        between Customer and Seller with respect to the subject matter hereof
        and supersedes all prior agreements, covenants, arrangements,
        communications, representations or warranties, whether oral or written,
        by any party or any officer, employee or representative of any party
        with respect to the subject matter hereof.

        United States.

     g. Each party shall comply with all applicable U.S. and foreign export

        technical data or products except in compliance with the applicable
        export control laws and regulations of the U.S. and any foreign country.

     "SpotLight System" shall mean a single SpotLight(TM) 2000 spectrum
     management system as described in Exhibit B.

     Any terms not defined herein shall have the same meanings as in the

2.   SCOPE

     Pursuant to the Agreement, Software will be delivered by Seller to Customer
     for use with a SpotLight System according to the terms of the Agreement and
     this Exhibit. Customer shall then become a licensee with respect to such
     Software.

3.   LICENSING GRANT

     3.1  Concurrent with execution of the Agreement, and subject to the terms
          and conditions set forth herein, Seller grants to Customer a
          revocable, non-exclusive and non-transferable license under Seller's
          applicable proprietary rights to use Software delivered to Customer
          hereunder to routinely operate and monitor the SpotLight System with
          which the Software was delivered.

     3.2  The Software licensing fees for the most current versions of the
          Embedded System Software and LampLighter Software (available at the
          time of purchase of a

                                    1 of 4
<PAGE>

          System. Software Updates are available under the Software Maintenance
          Program described in Exhibit D or for additional licensing fees.

4.   LIMITATIONS ON USE OF SOFTWARE

     4.1  Without the prior written consent of Seller, Customer shall only use
          the Software in conjunction with a single SpotLight System delivered
          to Customer under the terms of the Agreement.

     4.2  The license granted to Customer in Section 3 is personal and may only
          be transferred to another SpotLight or site or another entity in
          accordance with Section 11(b) of the Agreement.

     4.3  The Software is subject to laws protecting patents, trade secrets,
          know-how, confidentiality and copyright.

     4.4  Customer shall not translate, modify, adapt, decompile, disassemble,
          or reverse engineer the Software or any portion thereof.

     4.5  Unless otherwise expressly agreed by Seller, Customer shall not permit
          its directors, officers, employees or any other person under its
          direct or indirect control, to write, develop, produce, sell, or

          by means directly attributable to access to the Software (e.g. reverse
          engineering or copying).

     4.6  Customer shall not export the Software from the United States without
          the written permission of Seller. If written permission is granted for
          export of the Software, then Customer shall comply with all U.S. laws
          and regulations for such exports and shall hold Seller harmless,
          including legal fees and expenses for any violation or attempted
          violation of the U.S. export laws.

     4.7  Customer acknowledges that Seller owns the Software and that any
          rights therein not specifically granted in this License are the
          exclusive property of Seller.

5.   RIGHT TO COPY, PROTECTION AND SECURITY

     5.1  Software provided hereunder may be copied (for back-up purposes only)
          in whole or in part, in printed or machine-readable form for
          Customer's internal use only, provided, however, that no more than
          three (3) printed copies and three (3) machine-readable copies shall
          be in existence at any one time without the prior written consent of
          Seller, other than copies electronically resident in SpotLight
          Systems.

     5.2  With reference to any copyright notice of Seller associated with
          Software, Customer agrees to include the same on all copies it makes
          in whole or in part. Seller's copyright notice may appear in any of
          several forms, including machine-readable form. Use of a copyright
          notice on the Software does not imply that such has been published or
          otherwise made generally available to the public.

     5.3  Customer agrees to keep confidential, in accordance with the terms of
          the Agreement or a non disclosure agreement signed by the parties, and
          not provide or otherwise make available in any form any Software or
          its contents, or any portion

                                    2 of 4
<PAGE>

          thereof, or any documentation pertaining to the Software, to any
          person other than employees of Customer or Seller.

     5.4  Software is the sole and exclusive property of Seller and no title or
          ownership rights to the Software or any of its parts, including
          documentation, is transferred to Customer.

          take all reasonable measures to safeguard Software and to prevent its
          unauthorized use or duplication.

6.   REMEDIES

     Customer acknowledges that violation of the terms of this Exhibit or the
     Agreement shall cause Seller irreparable harm for which monetary damages
     may be inadequate, and Customer agrees that Seller may, in addition to any
     other legal or equitable remedy, seek temporary or permanent injunctive
     relief without the need to prove actual harm in order to protect Seller's
     interests.

7.   TERM

     Unless otherwise terminated, pursuant to Section 8 hereof, the term of the
     license granted pursuant to Section 3 herein shall be perpetual.

8.   TERMINATION

     8.1  The license granted hereunder may be terminated by Customer upon one
          (1) month's prior written notice.

     8.2  Seller may terminate the license granted hereunder if Customer is in
          material default of any of the terms and conditions of this Exhibit E
          and such termination shall be effective if Customer fails to correct
          such default within thirty (30) days after written notice thereof by
          Seller, provided, however, that if such default cannot reasonably be
          cured within thirty (30) days after written notice by Seller, and
          Customer diligently commences to correct such default within such
          thirty (30) days of written notice, the termination by Seller shall
          become effective if Customer fails to correct such default within
          ninety (90) days of such written notice. The provisions of Sections 4
          and 5 herein shall survive termination of any such license.

     8.3  In the event that Customer is required to return the Software,
          pursuant to Section 8(b) of the Purchase Agreement, or in the event
          that Customer returns a SpotLight System pursuant to Section 5(a)(2)
          of the Purchase Agreement, this license shall terminate immediately
          upon such return of the Software or Product to Seller.

     8.4  Within one (1) month after termination of the license granted
          hereunder, Customer shall furnish to Seller a document certifying that
          through its best efforts and to the best of its knowledge, the
          original and all copies in whole or in part of all Software, in any
          form, including any copy in an updated work, have been returned to
