                                                          Agreement No. 99006728

                           Products/Services: Buyer may at any time Terminate
                           any Order in whole or in part upon written notice to
                           Seller. In such event, Seller shall be entitled to
                           reasonable Termination charges consisting of its
                           actual and direct costs incurred to provide the
                           Products and Services ordered by Buyer but no more
                           than a percentage of the work performed or Products
                           delivered prior to Termination, minus salvage or
                           resale value of the Terminated Order. If requested,
                           Seller agrees to substantiate such costs with proof
                           satisfactory to Buyer. In no event shall the
                           Termination charges on any Order hereunder exceed the
                           Order price.

                           No Termination charges shall apply to Products not
                           specially manufactured for Buyer pursuant to any
                           Order which is Terminated at least thirty (30) days
                           prior to the required delivery date. Buyer shall not
                           be responsible for any work performed nor for any
                           costs incurred by Seller, Seller's sellers, or
                           Seller's subcontractors after Buyer has provided
                           notice of Termination. After the receipt of Buyer's
                           payment for such Terminated Services, Seller shall
                           deliver the physical embodiments, if any, of the
                           items charged to and paid by Buyer. The foregoing
                           Termination charges state the entire liability of
                           Buyer for Termination for convenience by Buyer of any
                           Order hereunder.

         C.       Partial Cancellation and Termination

                  Where a provision of this Agreement or applicable Laws and
                  Regulations permits Buyer to Terminate or Cancel an Order,
                  such Termination or Cancellation may, at Buyer's option, be
                  either complete or partial. In the case of a partial
                  Termination or Cancellation Buyer may, at its option, accept a
                  portion of the Products or Services covered by an Order and
                  pay Seller for such Products or Services at the unit prices
                  set forth in such Order. The right to Cancel an Order shall
                  also include the right to Cancel any other related Order.

         D.       Cancellation for Default

                  If Seller is in material default of any of its obligations
                  under this Agreement or applicable Orders and such default
                  continues for ten (10) days after written notice thereof is
                  given by Buyer, then in addition to all other rights and
                  remedies, at law or in equity, Buyer may Cancel this Agreement
                  and/or any Order which may be affected by such default without
                  any obligation or liability on the part of Buyer whatsoever.
                  Notwithstanding this paragraph D, additional provisions for
                  Cancellation of Orders hereunder are set forth in this
                  Agreement.

                  Buyer shall have the right to retain or return any Product
                  already received and accepted; provided, however, if Buyer
                  elects to return any Product, Seller shall reimburse Buyer the
                  cost of shipping any returned Product and amounts, if any,
                  previously paid by Buyer for such Product. Seller shall bear
                  all expenses for removal and return of such Product.

                  procedures within sixty (60) days of the commencement of such

         The following supersedes the General Agreement No. 98005906, section

         A.       TITLE

                  Title to Equipment purchased hereunder will vest in Buyer when
                  the Equipment has been delivered and accepted at the
                  destination specified in the applicable Order. If this
                  Agreement calls for additional Services such as unloading,
                  installation or the like to be performed after delivery,
                  Seller will retain risk of loss to the Equipment until the
                  additional Services have been performed to Buyer's
                  satisfaction. Title to Software will remain in Seller. Buyer
                  will have the right to make a reasonable number of copies of
                  the Software for use as authorized by OEM.

                  Product until delivery of the Product at the destination
                  specified in the applicable Order and acceptance by Buyer. In
                  the event that additional Services such as installation,
                  unloading or the like, are to be performed by Seller, the risk
                  of loss shall pass to Buyer after such additional Services
                  have been performed and the Product has been accepted by
                  Buyer. With respect to any loss or damage which occurs while
                  Seller has the risk of loss, Buyer shall notify Seller
                  promptly of any claim and shall cooperate with Seller to
                  facilitate making and settling any such claim.

                  After such delivery and acceptance, Buyer shall bear the risk
                  of loss of or damage to such Product, except to the extent
                  that any loss or damage arises out of or results from the
                  negligence or willful misconduct of Seller or its agents or
                  contractors.

         Each party hereto agrees to notify the other party hereto at least
         sixty (60) days prior to the expiration of any labor agreement. For any
         actual work stoppage, notification will be made within the first twelve
         (12) hours after such stoppage has occurred.

         For an emergency request by Buyer during any work stoppage, Seller will
         provide on-site technical support of Products and/or Services provided

         emergency service during a work stoppage, Seller will release
         sufficient information to a third party through a Non-Disclosure
         Agreement approved by Buyer to allow the requested Products and/or
         Services to be provided in the same manner as though Seller has
         provided same. Seller will receive Buyer's written approval prior to
         the release of any such information.

10.6     Tools and Equipment

         Unless otherwise specifically provided herein, Seller agrees to furnish
         all labor, tools and equipment (the "Tools") required for the
         performance of this Agreement. Upon completion of the Services, Seller
         agrees to promptly remove all tools, equipment, materials and debris
         from Buyer's premises. Should Seller use any Tools owned or rented by
         Buyer, Seller further agrees:

         (a)      To defend, indemnify and hold Buyer harmless from and against
                  any and all loss, liability, damage, expense, claim, demand or
                  suit (including attorney's fees and court costs) of any kind
                  and nature whatsoever (including but not limited to claims
                  resulting from injuries or death to persons or damage to
                  property) in any way arising out of or resulting from Seller's
                  maintenance, possession, operation, use, storage or movement
                  of the Tools or any accident occurring in connection
                  therewith.

         (b)      To accept the Tools "as is, where is" and that Buyer will have
                  no responsibility for the condition or state of repair
                  thereof.

         (c)      Not to remove the Tools from Buyer's premises and to return
                  them to Buyer upon completion of use, or at such earlier time
                  as Buyer may request, in the same condition as when received
                  by Seller, reasonable wear and tear excepted.

         All use of Tools by Seller will be subject to the provisions of the
         Section entitled LIABILITY, and Seller agrees to maintain at all times
         adequate insurance acceptable to Buyer to cover its indemnification
         obligations hereunder and provide Buyer, upon request, with evidence
         thereof.

10.7     Use of Buyer's Systems

         Buyer reserves the right to determine how Seller's personnel provided
         to perform Services hereunder will access Buyer's network remotely and
         locally.

         Seller agrees and promises to use the applicable Buyer computer systems
         on which the Services are provided in a professional and effective
         manner, and only for the purposes of the performance of this Agreement.
         Any other intentional use or misuse of such computer systems will
         constitute a breach of this Agreement.

         Seller acknowledges that any person Seller selects to work under this
         Agreement will be expected to fully comply with the known requirements,
         conditions, or restrictions applicable to the use of Buyer's computers
         or telephone network or applicable to access to Buyer's database,

         or restrictions by any of these persons. Seller further agrees to
         cooperate fully in any Buyer inquiry into alleged violations by
         Seller's personnel with respect to Buyer's computers, property or
         information.

10.8     Damages to Property and Live Equipment

         A.       Buyer shall notify Seller, of any damage to or theft of
                  tangible property, real or personal, caused directly or
                  indirectly by Seller and of circumstances, which it believes,
                  could give rise to such damage. Seller shall take precautions
                  and reasonable and necessary measures to prevent further
                  damage. Seller shall indemnify Buyer for such damage or loss
                  in accordance with the Section entitled INDEMNIFICATION.
                  Seller shall replace or temporarily repair such property. At
                  Buyer's or a third party owner's option and direction, Seller
                  shall restore or replace Buyer's or other's property to its
                  original condition, place such property in operational
                  condition or bear the cost of such restoration or replacement.

         B.       The continuity of Buyer's service is of paramount importance
                  and Seller shall at all times exercise the greatest care to
                  prevent damage to Buyer's property and shall not use any
                  materials, equipment or methods which, in the judgment of
                  Buyer, might endanger or interfere with Buyer's service to its
                  customers.

         C.       In the event of damage to "live" equipment caused by, or as a
                  result of Seller's negligent or reckless acts or omissions,
                  except to the extent that the specific act or omission
                  producing damage was expressly directed by Buyer, Seller shall
                  be liable in accordance with the provisions of the Section
                  entitled INDEMNIFICATION.

         agent when Equipment is ready for inspection, (b) give Buyer such
         reasonable opportunity to inspect such Equipment at any time prior to
         the scheduled shipment date, and (c) provide without charge any
         production testing facilities and personnel required to inspect the
         Equipment under the inspection instructions specified. Purchase of any
         Equipment under this Agreement is subject to Buyer's inspection and
         acceptance after delivery. It is mutually agreed that Buyer or Buyer's
         agent may develop inspection instructions which will be made a part of
         this Agreement at a later date by written agreement of the parties.
         Inspection or failure to inspect on any occasion will not affect
         Buyer's rights under warranty or other provisions of this Agreement.

10.10    Installation Services

         Seller agrees to install, at no additional charge to Buyer, all
         Products ordered hereunder, including all necessary cabling, connection
         with Buyer-supplied power, utility and communications services, and in
         all other respects make the Equipment ready for operational use. The
         Equipment will be deemed installed and ready for operational use at the
         conclusion of a successful Acceptance Test performed at the
         Installation Site, which demonstrates that the Equipment meets minimum
         design capabilities. Seller will provide Buyer with written
         documentation of the successful Acceptance Test and certify, by the
         Installation Date, that the Equipment is ready for operational use in
         accordance with Buyer's Order.

         Installation of the Software by Buyer or Seller will consist of a
         version that will perform in accordance with the corresponding
         published performance Specifications and will include a demonstration
         of the Software's features and functions using Seller's standard
         demonstration procedure of the installed Software on Buyer's computer
         system.

                            Proprietary Information
     The information contained herein is not for use of disclosure outside

         The purpose of the installation demonstration will be to confirm that
         all Software ordered has been entered into Buyer's program library and
         that such Software functions in accordance with Seller's published
         performance Specifications associated therewith.

         The demonstration will be considered successfully completed when the
         Software output results match the standard set of results provided by
         Seller.

         If Seller installs the Software, Seller will certify in writing to
         Buyer, at the successful completion of the installation demonstration,
         that the Software has been properly installed and performs in
         accordance with Seller's published performance Specifications
         applicable thereto. If Buyer installs same, Seller agrees to provide
         complete installation instructions with the Software and telephone
         consultation during Seller's business hours, on the proper installation
         thereof at no additional charge to Buyer.

10.11    Installation Performance

         Buyer retains the right to determine the installation vendor for
         Products. If Installation of Products purchased hereunder is to be
         performed by Seller, the applicable Order(s) shall so indicate. If
         Seller or Seller's subcontractors are chosen to install the Products,
         Installation shall be performed in accordance with TP76300
         "Southwestern Bell Telephone Installation Guide", dated September 1996
         for SWBT or with "PACIFIC BELL/NEVADA BELL CENTRAL OFFICE EQUIPMENT
         INSTALLATION AND JOB ACCEPTANCE HANDBOOK" dated November 1994 for
         PACIFIC ("Installation Handbook"), or Telcordia Publication
         TR-NWT-001275" CO Environment Installation/Removal Generic
         Requirements" for Affiliate installations and as subsequently amended
         from time to time, which are incorporated herein by this reference. In
         addition, Seller agrees to adhere to Seller's own installation
         standards to the extent such standards do not reduce or detract from
         Buyer's installation requirements or impair or impact the design or
         operation of the Products.

         In order to install Products in SWBT's market areas, Seller must obtain
         prior approval from SWBT's local Vendor Certification Committees. In
         order to install Products in PACIFIC's market areas, Seller must be
         certified by PACIFIC'S Installation Vendor (IVEN) process as a
         qualified installation vendor before starting any Installation
         activity. Seller's intended use of any subcontractor or agent to
         install Products will likewise be subject to prior approval, which
         approval will not be unreasonably withheld.

         Seller agrees to pay certain liquidated damages for failure to (1) meet
         scheduled completion dates, and (2) perform central office equipment
         installation functions as requested by Buyer on the Order and in
         accordance with Buyer's specification.

         The amount of such damages shall be in accordance with the following
         schedule:

         1.   Installation Requirements

         o        Seller shall perform Central Office Equipment Installation
                  functions as requested by Buyer on the Order and in accordance
                  with Buyer's specification. Should Seller's performance or
                  lack thereof result in an out of service condition, the
                  following charges will apply: Out of Service Condition -
                  Seller will forfeit twenty percent (20%) of installation fee.

         o        An out of service condition will require a positive reporting
                  of the incident to the SWBT Area Manager - Maintenance

                  Network Operations supervisor for SWBT and PACIFIC and Buyer's
                  representative (as described in Buyer's Installation
                  Handbooks).

         2.       Completion Dates

         o        Installation Services shall be completed in accordance with
                  Buyer's schedule(s) and/or mutually negotiated completion
                  schedule(s). Seller will forfeit ten percent (10%) of
                  installation fee for failure to meet scheduled or mutually
                  agreed advance service and/or job completion dates.

         Seller shall not be liable or responsible for liquidated damages for
         any delay caused by (1) Buyer changes, revisions or modifications, or
         special requirements of Buyer not communicated to Seller, (2) Buyer
         changes in scheduled dates, (3) failure of Buyer to provide any item to
         be furnished by Buyer, (4) failure of Buyer to furnish required
         order/engineering information prior to Seller's standard engineering
         interval, or (5) other reasons attributable to Buyer.

         Any liquidated damages for which Seller is liable pursuant to this
         clause shall be credited against the invoice for the affected Order,
         provided, however, that if the relevant invoice has been paid in full,
         the applicable amount for liquidated damages shall be remitted to Buyer
         by check.

10.12    Installation/Cutover Assistance

         If requested by Buyer, Seller agrees to make available at the
         installation site, without charge, a field engineer to render
         installation and cutover assistance as required by Buyer for the
         initial installation/cutover in each of Buyer's operating areas.

10.13    Acceptance

         Buyer reserves the right to accept or reject Products and Services
         after the delivery (including installation or other work, if required)
         of Products at the location designated in the applicable Order and
         after the performance of Services if such Products or Services fail to
         meet the applicable Specifications. If, prior to acceptance by Buyer,
         any of the Products or Services are found to be not in strict
         conformance to this Agreement, including the applicable Order, Buyer
         shall have the right (a) to reject the same and cancel any affected
         Order(s) or, (b) at its option, (1) in the case of Products, require
         that such Products be repaired or replaced promptly at Seller's risk
         and expense (including freight charges) and (2) in the case of
         Services, require the performance or reperformance of such Services.
         Buyer's use of Products for revenue generating purposes shall not
         thereby constitute acceptance. Installation of replacement Equipment
         will be within the time period mutually agreed upon by the parties in
         writing. Buyer may terminate the applicable Order and request the
         removal of the Equipment with no charges or penalties. Acceptance of
         Products by Buyer shall be without prejudice to Buyer's right to revoke
         acceptance pursuant to the Uniform Commercial Code.

         Buyer reserves the right to conduct an Acceptance Test of the Products
         and Services during the Acceptance Period starting the day after Seller
         certifies in writing that the Equipment is ready for Acceptance
         Testing, if Seller installs the Equipment, or the day following
         completion of installation by Buyer; provided, however, Acceptance
         Testing will not begin until Buyer personnel have been trained by OEM
         to operate the Equipment. In such excepted case, Acceptance Testing
         will begin the business day following completion of the required
         training. Testing will be performed to determine whether:

         associated necessary training required ensuring that technicians
         perform quality installations. Seller therefore, agrees, to provide
         training on the installation of all Equipment purchased hereunder to
         Buyer or any other party reasonably designated by Buyer. Such
         installation training shall include, but not be limited to:

                  Equipment.

         2.       The proper order in which the different elements that comprise
                  the system must be installed and the location of each element.

         5.       Proper routing and terminating of power cable and connectors.

         6.       Proper routing and termination of ground cable and connectors.

         7.       Any unique features in the design of the system that if not
                  properly installed may adversely affect the operation of the
                  intelligent network element.

         8.       The order and proper methods for applying power to the system
                  when it is initially powered up so it does not interfere with
                  the operation of any network element already in service. Other
                  installation requirements are specified in Buyer's
                  "Installation Handbook".

10.15    Relocation

         Upon thirty (30) days' prior written notice from Buyer, Seller agrees
         to prepare for relocation and reinstall Equipment purchased hereunder
         at any other site at Buyer's expense. The charge will be at no more
         than Seller's maintenance rates set forth herein.

11.0     REPAIR AND MAINTENANCE

11.1     Notice of Delays & Liquidated Damages

         A.       Whenever any actual or potential cause delays or threatens to
                  delay Seller's performance with respect to delivery, including
                  the availability of promised features or functionality, in
                  addition to all other Seller obligations and Buyer remedies,
                  Seller shall immediately and regularly thereafter, but no less
                  often than twice-a-month, so notify Buyer in writing. Such
                  notice shall include all relevant information concerning the
                  actual or potential cause of the delay and its background.
                  During the period such actual or potential cause exists,
                  Seller shall keep Buyer advised of its effect on Seller's
                  performance and of the measures being taken to remove it. For
                  purposes of this section, promised feature or functions shall
                  include Seller's Product Specifications for a promised feature
                  or function and Seller's written commitments to Buyer for
                  delivery of a promised feature or function.

        B.        Seller shall be given twenty (20) business days from the
                  occurrence of such failure to cure its breach and/or work with
                  Buyer to develop a plan, which will minimize Buyer's
                  liability. Although Buyer shall have the final authority to
                  approve any such plan, Buyer shall not unreasonably delay or
                  withhold approval of any technically viable plan that provides
                  a reasonable remedy for Seller's failure to meet the agreed
                  upon delivery or completion date as specified above.

                  Seller shall pay to Buyer in total satisfaction of this
                  provision as liquidated damages and not as a penalty the
                  lesser of either (i) an amount equal to one percent (1%) of
                  the price of the Products per day for such delayed Products,
                  or (ii) one thousand dollars ($1,000), for each day of delay
                  occurring after the end of the twenty day cure period set
                  forth in the preceding paragraph until the actual Delivery
                  Date. Liquidated damages under this section shall in no event
                  exceed 100% of the dollar volume of the portion of the Order
                  and regularly thereafter, but no less than twice-a-month, so
                  notify Buyer in writing. Such notice shall include all
                  relevant information concerning the actual or potential cause
                  of the delay and its background. During the period such actual
                  or potential cause

                                                          Agreement No. 99006728

                  exists, Seller shall keep Buyer advised of its effect on
                  Seller's performance and of the measures being taken to remove
                  it. For purposes of this section, promised feature or
                  functions shall include Seller's Product Specifications for a
                  promised feature or function and Seller's written commitments
                  to Buyer for delivery of a promised feature or function.

         B.       Seller shall be given twenty (20) business days from the
                  occurrence of such failure to cure its breach and/or work with
                  Buyer to develop a plan, which will minimize Buyer's
                  liability. Although Buyer shall have the final authority to
                  approve any such plan, Buyer shall not unreasonably delay or
                  withhold approval of any technically viable plan that provides
                  a reasonable remedy for Seller's failure to meet the agreed
                  upon delivery or completion date as specified above.

                  Seller shall pay to Buyer in total satisfaction of this
                  provision as liquidated damages and not as a penalty the
                  lesser of either (i) an amount equal to one percent (1%) of
                  the price of the Products per day for such delayed Products,
                  or (ii) one thousand dollars ($1,000), for each day of delay
                  occurring after the end of the twenty day cure period set
                  forth in the preceding paragraph until the actual Delivery
                  Date. Liquidated damages under this section shall in no event
                  exceed 100% of the dollar volume of the portion of the Order
                  which is delayed, or which cannot be deployed because of the
                  delayed delivery of other parts of the Order. Such amount
                  shall be paid, at Buyer's election, in the form of either cash
                  (net 30 days after notice), credit, or a Product credit on a
                  going-forward basis.

                  This liquidated damage amount shall not apply where the
                  lateness was caused by failure of a vendor to fulfill a
                  contractual obligation to Seller where such failure was beyond
                  the vendor's reasonable control, such as by Force Majeure, as
                  defined in this Agreement. Buyer shall give Seller the
                  flexibility to ship partial order quantities if deployment is
                  reasonably feasible consistent with Buyer's deployment plans
                  and personnel availability, in order to minimize liquidated
                  damages. In addition to the foregoing, Seller shall diligently
                  use proactive efforts to remedy the shortfall. Such efforts
                  include, at no additional charge to Buyer, the following: a)
                  an automatic and immediate allocation of resources to meet the
                  failed commitment (or anticipated shortfall); b) the provision
                  of hotlot or expedite status for material which is in short
                  supply; c) expedited shipment; and, d) the waiving of
                  lead-time requirements for further orders as necessary to meet
                  the commitment.

                  In the event that Seller does not deliver Products including
                  delivery of promised features, to Buyer or complete
                  performance of Services on or before such extended Delivery
                  Date (which shall, unless the parties agree to a shorter
                  period, be at least thirty (30) business days after the
                  originally scheduled Delivery Date), Buyer may (1) cancel such
                  Order or (2) extend the Delivery Date and hereby reserves its
                  rights as stated above. No payments, progress or otherwise,
                  made by Buyer to Seller after the scheduled Delivery Date
                  shall constitute a waiver of liquidated damages, and receipt
                  of liquidated damages shall be in lieu of consequential and
                  incidental damages resulting from Seller's breach.

         Seller agrees that all rights, title and interest in and to all
         original works of authorship which Seller produces or composes in

         and shall belong to the Buyer, including all copyrights thereon, and
         the rights to obtain registrations of copyrights thereon throughout the
         world. In the event that such works contemplated hereunder as works
         made for hire shall not be considered works made for hire, Seller
         hereby assigns such Works and all rights, title and interest in them to
         Buyer.

This Product Resale Agreement ("Agreement") is made by and between World Wide
Technology, Inc., a Missouri corporation, with offices at 127 Weldon Parkway, St
Louis Missouri 63043 ("Vendor") and Lucent Technologies Inc., a Delaware
corporation, with its principal place of business at 600 Mountain Avenue, Murray
Hill, New Jersey 07974 ("Lucent").

WHEREAS, Lucent desires to sell certain 5ESS(R) electronic switch system
apparatus [*Confidential treatment will be requested.] ("Product(s)") and is
desirous of having another company stock and furnish equipment to Ameritech
Services, Inc. ("ASI"); and

WHEREAS, Vendor represents that it is a reseller of telecommunications equipment
and has in place the facilities and organization to stock and furnish such
equipment to ASI; and

WHEREAS, Lucent believes that ASI desires to make purchases of Product(s) from a
certified Minority Business Enterprise ("MBE"); and

WHEREAS, Vendor represents and warrants that it is a certified MBE and desires
to purchase Product(s) for the sole purpose of reselling such Product(s) to ASI.

NOW THEREFORE the parties agree as follows:

1.       SCOPE OF AGREEMENT

(a)      The terms and conditions of this Agreement shall apply to transactions
         in which Lucent furnishes Product(s) to Vendor so that Vendor may
         furnish such Product solely to and for ASI.

(b)      In consideration of the covenants by Vendor contained herein, Vendor is
         granted the right to obtain the Products [*Confidential treatment will
         be requested.], plus such additional items as Lucent may from time to
         time in writing agree to furnish to Vendor, solely for the purpose of
         selling, or otherwise furnishing Product to ASI. Vendor shall only sell
         or otherwise furnish Product to ASI against ASI orders placed with
         Vendor. Products purchased by Vendor from Lucent pursuant to this
         Agreement shall not be resold, assigned or delivered to any other
         person or entity other than ASI and are sold solely on the
         representation that such purchases are related to the sale and delivery
         of Product to ASI. Any Products Vendor desires to purchase for work
         competitively awarded by ASI shall be purchased through other
         distribution channels or as may be mutually agreed by the parties.

(c)      Vendor is also a participant in Lucent's Value Added Reseller ("VAR")
         program and acknowledges and agrees that in performing for and on
         behalf of ASI, Vendor is not participating in the VAR program and that
         any purchases for or on behalf of ASI hereunder shall not be counted
         towards any awards, discounts, credits or minimum purchase commitments
         as may exist under the VAR program. Vendor agrees that it shall not
         make any claim for any such benefits for the VAR program for any sales,
         deliveries or efforts hereunder.

                                                                    Page 3 of 23

(d)      VENDOR AGREES THAT THE TERMS AND CONDITIONS OF PARAGRAPHS 1(a) THROUGH
         1(c) ARE MATERIAL TO THE AGREEMENT AND ANY BREACH THEREOF BY VENDOR
         SHALL BE A MATERIAL BREACH AND CAUSE FOR TERMINATION AS PROVIDED
         HEREIN.

(e)      No payment of any fee is required as a condition of such grant. Lucent
         may, without the consent of Vendor, delete or add any Product available
         to Vendor. Lucent agrees to provide notice to Vendor in the event such
         additions and deletions to the Products available hereunder.

(f)      Vendor acknowledges that this Agreement does not confer upon it an
         exclusive right to market Product or any other items and Lucent
         expressly reserves the right to contract with others to market Product
         or any other items to ASI, and to itself engage in such marketing, in
         competition with Vendor.

         delivered to Vendor [*Confidential treatment will be requested.].

c)       "ASI" shall mean Ameritech Services, Inc. as it exists on the day of
         this Agreement and its current Affiliate(s) in the five (5) state
         Ameritech region which are formally authorized by ASI to purchase
         Products from Lucent.

d)       "Licensed Material" shall mean Software in object code form for which

         for the furnishing of the Products including, without limitation,
         Lucent's contract number, the date of the order, the shipping

function or are recommended to enhance safety. Lucent may use either new,
reconditioned, refurbished or remanufactured Products or parts in the furnishing
of Products, spares, replacement parts or repairs under this Agreement.

Vendor acknowledges that Lucent will be changing during the term of this

Vendor in writing ("Name Change Notice"). Said Name Change Notice shall include,
without limitation:

         symbol, code, and/or specification selected by Lucent (in its sole and

         the use by Vendor of such new trade name, logo, trademark, trade

(including, without limitation, Clause 20, TRADEMARKS) to use any mark (as
defined in Clause 20) which contains any reference to "AT&T" or any
abbreviation, contraction or simulation thereof shall be terminated and null and
void and thereupon all rights of Vendor under this Agreement to use any mark

         arising from the provision of or the transfer, sale, license, or use of
         Products, or other items provided by Lucent. Taxes reimbursable under
         this clause shall be separately listed on the invoice.

(f)      Lucent shall not collect the otherwise applicable tax if Vendor's
         purchase is exempt from Lucent's collection of such tax and a valid tax
         exemption certificate is furnished by Vendor to Lucent.

(g)      In no event shall Vendor's payment, as set forth in this Clause 13,
         INVOICING AND TERMS OF PAYMENT, be contingent on Vendor's resale of
         Product(s) or product(s) to ASI.

14.      DELIVERY, TITLE AND RISK OF LOSS

Shipments of Product shall be made FOB destination and title and risk of loss to
such Products shall pass to Vendor upon delivery to the Vendor. Shipments of

Licensed Materials shall pass to Vendor upon delivery to the Vendor. Title to
Licensed Materials shall remain in Lucent. Vendor shall notify Lucent promptly
of any claim with respect to loss which occurred while Lucent bears the risk of

destination shown on the order, prepaid and added to the invoice as may be
specified on individual orders. When Vendor requests Lucent to arrange the
transportation of the Product, Lucent shall ship all Products freight collect.

carrier based on the best rate, as negotiated by Lucent, and Vendor shall pay
Lucent's transportation costs in accordance with the standard factors then in
effect.

                  the other.

16.      USE OF INFORMATION

All Information which bears a proprietary legend or notice restricting its use,
copying, or dissemination shall remain the property of the furnishing party
("Information"). The furnishing party grants the receiving party the right to
use such Information only as follows: such Information (1) shall not be
reproduced or copied, in whole or in part, except for use as authorized in this
Agreement; and (2) shall, together with any full or partial copies thereof; be
returned or destroyed when no longer needed. When Lucent is the receiving party,
Lucent shall use such information only for the purpose of performing under this
Agreement. When Vendor is the receiving party, Vendor shall use such Information
only (1) to evaluate or order Lucent's Products or (2) to install, operate and
maintain the particular Products for which it was originally furnished. Unless
the furnishing party consents in writing, such Information shall be held in
confidence by the receiving party, except for that part, if any, which is known
to the receiving party free of any confidential obligation, or which becomes
generally known to the public through acts not attributable to the receiving
party. The receiving party may disclose such Information to other persons, upon
the furnishing party's prior written authorization, but solely to perform acts
which this clause expressly authorizes the receiving party to perform itself and
further provided such other person agrees in writing (a copy of which writing
will be provided to the furnishing party at its request) to the same conditions
respecting use of Information contained in this clause and to any other
reasonable conditions requested by the furnishing party.

17.      INFRINGEMENT

In the event of any claim, action, proceeding or suit by a third party against
Vendor alleging an infringement of any United States patent, United States
copyright, or United States trademark, or a violation in the United States of
any trade secret or proprietary rights by reason of the use, in accordance with
Lucent's or other applicable specifications, of any Product, Licensed Material
(software or related documentation), if any, or other item furnished by Lucent
to Vendor under this Agreement, Lucent, at its expense, will defend Vendor,
subject to the conditions and exceptions stated below. Lucent will reimburse
Vendor for any cost, expense or attorney's fee, incurred at Lucent's written
request or authorization, and will indemnify Vendor against any liability
assessed against Vendor by final judgment on account of such infringement or
violation arising out of such use.

If Vendor's or ASI's use shall be enjoined or in Lucent's opinion is likely to
be enjoined, Lucent will, at its expense and at its option, either (a) replace
the affected Product, Licensed Material or other item furnished pursuant to this
Agreement with a suitable substitute free of any infringement or violation, (b)
modify it so that it will be free of the infringement or violation, or (c)
procure for Vendor or ASI a license or other right to use it. If none of the
foregoing options is practical, Lucent will accept the return of the enjoined
Product, Licensed Material or other item and refund to Vendor any amounts paid
to Lucent less a reasonable charge for any actual period of use by Vendor.

Vendor shall give Lucent prompt written notice of all such claims, actions,
proceedings or suits alleging infringement or violation and Lucent shall have
full and complete authority to assume the sole defense thereof; including
appeals, and to settle same. Vendor shall, upon Lucent's request and at Lucent's
expense, furnish all information and assistance available to Vendor and
cooperate in every reasonable way to facilitate the defense and/or settlement of
any such claim, action, proceeding or suit.

No undertaking of Lucent under this section shall extend to any such alleged
infringement or violation to the extent that it: (a) arises from adherence to
design modifications, specifications, drawings, or written instructions which
Lucent is directed by Vendor or ASI to follow, but only if such alleged
infringement or violation does not reside in corresponding commercial Product or
Licensed Material of Lucent's design or selection; or (b) arises from adherence
to instructions to apply Vendor's or ASI's trademark, trade name, or other
company identification; or (c) resides in a Product or Licensed Material which
is not of Lucent's origin and which is furnished by Vendor or ASI to Lucent for
use under this Agreement; or (d) relates to use of Products, Licensed Materials
or other items provided by Lucent in combinations with other Products, Licensed
Materials or other items, furnished either by Lucent or others, which
combination was not installed, recommended or otherwise approved by Lucent. In
the foregoing cases (a) through (d), Vendor will defend and save Lucent
harmless, subject to the same terms and conditions and exceptions stated above
with respect to Lucent's rights and obligations under this clause.

20.      TRADEMARKS

Vendor will not, without Lucent's express written permission, use in marketing,
advertising, publicity, or otherwise any trade name, trademark, trade device,
service mark, symbol, code, or specification or any abbreviation, contraction,
or simulation thereof ("mark") of the Lucent companies nor shall Vendor claim
any ownership therein. Vendor shall not remove, deface, alter or otherwise
obscure any mark of the Lucent companies which is on a Product sold under this
Agreement nor shall Vendor place any mark of any other company on any such
Product. Any such usage shall inure to the benefit of the Lucent company mark
owner. As used in this Clause the term "Lucent" means Lucent Technologies Inc.,
Bell Labs and its Affiliated companies.

21.      LEGISLATION AND GOVERNMENTAL REGULATIONS

Vendor shall at all times comply with all applicable requirements of federal,
state and local laws, ordinances, administrative rules and regulations. Vendor
shall contractually require its subcontractors, distributors and agents to
comply with all such legal requirements as well, and Vendor shall indemnify,
defend and hold harmless Lucent for any damages, losses, costs, or penalties
incurred by Lucent by virtue of such noncompliance by Vendor or its
subcontractors, distributors, or agents. If requested by Lucent, Vendor shall
advise Lucent in writing of the identity and addresses of its subcontractors,
distributors and agents in connection with the Products.

22.      TERMINATION OF ORDERS

Vendor may, upon notice to Lucent, and upon terms that will compensate Lucent
from all loss, terminate any order or portion thereof, issue a "hold" on an
order, or suspend performance under the Agreement in whole or in part, except
with respect to Products which have already been shipped or services which have
already been performed. Vendor's liability to Lucent for any

such termination, "hold" or suspension shall include, but not be limited to, the
price of all services performed and of Products delivered or held for
disposition, loss of profits, incurred costs (including charges made by Lucent
suppliers), work in progress, and an allocation of general and administrative
expenses.

23.      TERMINATION OF AGREEMENT

(a)      Either party may terminate this Agreement without cause or reason
         whatsoever upon sixty (60) days prior written notice to the other
         setting forth the effective date of such termination. The termination
         of this Agreement shall not affect the obligations of the parties with
         respect to any orders previously entered into hereunder, and the terms
         and conditions of this Agreement shall continue to apply to such orders
         as if this Agreement had not been terminated.

         Upon termination of this Agreement without cause pursuant to this
         paragraph neither party shall be liable to the other, either for
         compensation or for damages of any kind or character whatsoever,
         whether on account of the loss by Lucent or Vendor of present or
         prospective profits on sales or anticipated sales, or expenditures,
         investments, or commitments made in connection therewith or in
         connection with the establishment, development or maintenance or
         Vendor's business, or on account of any other cause or thing
         whatsoever, provided that termination shall not prejudice or otherwise
         affect the rights or liability of the parties with respect to Products
         theretofore sold hereunder, or any indebtedness then owing by either
         party to the other.

(b)      Either party may terminate this Agreement, immediately, upon
         twenty-four (24) hours written notice:

         (i)      if the other party files a petition in bankruptcy, or is
                  adjudicated bankrupt, or makes a general assignment for the
                  benefit of creditors, or becomes insolvent, or is otherwise
                  unable to meet its business obligations for a period of six
                  (6) months. Such party shall promptly and fully inform the
                  other party of the imminence or occurrence of any event
                  described in this subparagraph; or

         (ii)     in the event of change in the controlling ownership of Vendor
                  or in the event of a sale or assumption of all or
                  substantially all of the assets of Vendor on or after the
                  effective date of this Agreement, if such change, sale or
                  assumption is unacceptable by Lucent.

         (iii)    in the event the agreement between Vendor and ASI terminates
                  in which event Vendor shall notify Lucent of said termination
                  immediately and in writing.

(c)      Either party may terminate this Agreement if the other party breaches
         any of the material terms and conditions of this Agreement and the
         other party fails to cure such breach within thirty (30) days after
         written notice thereof from the non-breaching party.

(d)      Notwithstanding any other terms and provisions of this Agreement or
         other arrangements agreed to by the parties, termination of this
         Agreement shall automatically accelerate the due date of all invoices
         for Products such that they shall become immediately due and payable on
         the effective date of termination.

(e)      Upon notice of termination, Lucent shall be entitled to reject all or a
         part of any orders received from Vendor after notice but prior to the
         effective date of termination.

Notwithstanding any credit terms made available to Vendor prior to that time,
any Product shipped after notice of termination and prior to effective date of
termination shall be paid for by certified or cashier's check prior to shipment.
Upon termination or non-renewal of this Agreement, Vendor shall immediately:

         (1)      Discontinue any and all use of marks (as defined in the Clause
                  TRADEMARKS) except to identify the Products, including but not
                  limited to such use in advertising or business material of
                  Vendor;

         (2)      Remove and return to Lucent or destroy at Lucent's request,
                  any and all promotional material supplied without charge by
                  Lucent;

         (3)      Return, upon request, all Lucent Information as described in
                  the paragraph Use of Information except that which Lucent
                  agrees is necessary to operate and maintain previously
                  furnished Products;

         (4)      Cease holding itself out, in any other manner, as a Vendor
                  capable of purchasing or obtaining Products for or on behalf
                  of ASI directly from Lucent; and

         (5)      Notify ASI and others who may, at the initiation of Vendor,
                  identify, list or publish Vendor's name as a Vendor capable of
                  purchasing or obtaining Products for or on behalf of ASI
                  (including but not limited to publishers of other business
                  directories) to discontinue such listings.

24.      SURVIVAL OF OBLIGATIONS

The respective obligations of Vendor and Lucent under this Agreement which by
their nature would continue beyond the termination, cancellation or expiration
hereof shall survive such termination, cancellation or expiration.

25.      FORCE MAJEURE

Except with respect to Vendor's obligation to make timely payments, neither
party shall be liable to the other party for any loss, damage, delay or failure
of performance resulting directly or indirectly from any cause which is beyond
its reasonable control, including, but not limited to the elements;
extraordinary traffic conditions, riots; civil disturbances, wars; states of
belligerency or acts of the public enemy; labor disputes; strikes, work
stoppages, inability to secure raw

materials, product or transportation facilities; or the laws, regulations, acts
or failure to act of any governmental authority, including but not limited to
denial of a U.S. Export License, hereinafter referred to as "Force Majeure". A
Party shall promptly notify the other party of the occurrence of a Force Majeure
event and the notifying party shall be excused from any further performance of
these obligations affected by the Force Majeure event for as long as such Force
Majeure event continues and such party uses and continues to use its best
efforts to recommence performance. Failure of either party to perform under this
Agreement because of the endurance of a Force Majeure event for more than three
(3) months will represent grounds by either party for its termination of the
portion of this Agreement affected by the Force Majeure event.

26.      ASSIGNMENT

Except as provided in this clause, neither party shall assign this Agreement or
any right or interest under this Agreement, nor delegate any work or obligation
to be performed under this Agreement, (an "Assignment") without the other
party's prior written consent. Nothing shall preclude a party from employing a
subcontractor in carrying out its obligations under this Agreement, but a
party's use of such subcontractor shall not release the party from its
obligations under this Agreement. An attempted assignment or delegation in
contravention of this clause shall be void and ineffective. Lucent has the sole
right to assign this Agreement and to assign its rights and delegate its duties
under this Agreement, in whole or in part, at any time and without Vendor's
consent, to any corporate parent or to any present Affiliate or to any
combination of the foregoing, provided that Lucent give prompt written notice of
such assignment to Vendor.

27.      SEVERABILITY

If any provision in this Agreement, or any portion thereof is subsequently held
to be invalid or unenforceable under any applicable statute or rule of law, then
that provision or portion notwithstanding, this Agreement shall remain in full
force and effect and such provision or portion shall be deemed omitted and this
Agreement shall be construed as if such invalid or unenforceable provision or
portion had not been contained herein.

28.      RELEASE VOID

Neither party shall require release or waivers of any personal rights from
representatives of the other in connection with visits to its premises and both
parties agree that no such releases or waivers shall be pleaded by them in any
action or proceeding.

29.      NON-WAIVER

No waiver of the terms and conditions of this Agreement, or the failure of
either party to strictly enforce any term or condition of this Agreement on one
or more occasions shall be construed as a waiver of the same or of any other
term or condition of this Agreement on any other occasion.

30.      CHOICE OF LAW

The construction, interpretation and performance of this Agreement shall be
governed by the laws of the State of New York, except for its conflicts of law
provisions.

31.      TECHNOLOGY OWNERSHIP

Lucent retains sole ownership of the design, assembly, testing rights and
information, regardless of Vendor's contribution to the value of those rights,
design and information. Lucent's sale of the Products to Vendor; Lucent's grant
to Vendor of the right to assemble, package, and sell the Product, conveys no
ownership rights whatsoever in any Product or the Product.

32.      NOTICES

All notices, requests, approvals and other communications ("Notices") required
or allowed under this Agreement shall be in writing and addressed as set forth
below or to such other person and/or address as either party may designate by
written Notice pursuant hereto. Such Notices shall be deemed to have been given
when received. Notices may be delivered by hand or sent by prepaid certified or
registered airmail, confirmed facsimile or electronic mail, provided a copy is
also forwarded by prepaid registered airmail.

33.      PURCHASE MONEY SECURITY INTEREST

(a)      Subject to Lucent's prior written notice hereunder to Vendor of
         Lucent's intent to file purchase money security documents as set forth
         in the following and Vendor's failure to resolve any default(s) leading
         to such action within ten (10) days of Lucent's notice, Lucent reserves
         and Vendor agrees that Lucent shall have a purchase money security
         interest in all Products heretofore sold or hereafter sold to Vendor by
         Lucent under this Agreement, until any and all payments and charges due
         Lucent under this Agreement including, without limitation, shipping and
         installation charges, are paid in full. Lucent shall have the right, at
         any time during the Term and without notice to Vendor, to file in any
         state or local jurisdiction such financing statements (e.g., UCC1
         financing statements) as Lucent deems necessary to perfect its purchase
         money security interest

         hereunder. Vendor agrees to execute and deliver to Lucent all such
         financing statements and other documents as Lucent deems necessary to
         perfect its purchase money security interest hereunder. Notwithstanding
         the foregoing obligation, Vendor hereby irrevocably appoints Lucent as
         its attorney-in-fact for purposes of executing and filing such
         financing statements and such other documents prepared by Lucent or its
         designated agent for purposes of perfecting Lucent's security interest
         hereunder. Vendor also agrees that this Agreement may be filed by
         Lucent in any state or local jurisdiction as a financing statement (or
         as other evidence of the Lucent's purchase money security interest).

(b)      In addition to any other remedy available to Lucent as provided herein,
         by common law and by statute, Lucent may exercise its right to reclaim
         all Products sold to Vendor pursuant to U.C.C. Section 2-702 or such
         other applicable provision as it may exist from state to state, upon
         discovery of Vendor's insolvency, provided Lucent demands in writing
         reclamation of such Products before ten (10) days after receipt of such
         Products by Vendor, or if such 10 day period expires after the
         commencement of a bankruptcy case, before twenty (20) days after
         receipt of such Products by the Vendor.

34.      SETTLEMENT OF DISPUTES

The following procedures shall apply after the Effective Date to any dispute or
disagreement between the parties arising out of this Agreement, provided,
however, that this Clause shall not apply to indemnification claims arising
under this Agreement nor to actions for injunctive relief by one party against
the other.

(a)      Either party may give written notification of such dispute or
         disagreement to the other party, if the other party is Vendor, to the
         President and CEO of Vendor, or if the other party is Lucent, to the
         Vice President Sales, ASI Region ("RVP") (together being the Senior
         Executive Officers or "SEOs") and

(b)      The SEOs shall communicate with each other promptly with a view to
         resolving such dispute or disagreement within sixty (60) days of
         commencing their negotiations (or such extended period as the SEOs
         agree is appropriate in any case).

(c)      The giving of any notice regarding any dispute or disagreement
         hereunder shall toll the running of all applicable statutes of
         limitation until the later of (a) ninety (90) days following the giving
         of such notice or (b) thirty (30) days following the termination of
         discussions between the SEOs.

35.      GRANT OF LICENSE

(a)      The license for Licensed Materials with "Tear-Me" or "Tear-Open"
         licenses shall be as provided in those licenses and shall be provided
         by Vendor in their unopened original package to the end-user.

(b)      For all other Licensed Materials which are provided to Vendor for its
         own use, Lucent retains title to the Licensed Materials and grants
         Vendor a personal, non-transferable (except as provided in paragraph
         (c) below) and non-exclusive license to use Licensed Materials in the
         territory on a single designated processor for its own business
         operations. The Licensed Materials shall not be copied in whole or in
         part except as necessary for authorized use and each copy shall bear
         the same copyright and proprietary marks as the original. Vendor shall
         not reverse engineer, decompile or disassemble any Software to obtain
         corresponding Source Code.

(c)      Lucent grants to Vendor the right to sublicense Licensed Materials to
         ASI only, provided Vendor obtains a written license agreement from its
         sublicensee which provides that it accepts the license under the terms
         provided in the GPA between ASI and Lucent.

36.      CLAUSE HEADINGS

38.      AGREEMENT

(a)      The terms and conditions contained in this Agreement supersede all
         prior oral or written understandings between the parties and shall
         constitute the entire Agreement between them concerning the subject
         matter of this Agreement and shall not be contradicted, explained or
         supplemented by any course of dealing between Lucent or any of its
         Affiliates and Vendor or any of its Affiliates. Lucent's employees,
         statements and its advertisements or descriptions other than its
         published specifications do not constitute warranties or other
         contractual obligations and shall not be relied upon by Vendor as such.
         There are no understandings or representations, express or implied, not
         expressly set forth in this Agreement. No terms or conditions contained
         in any order or other form originated by Vendor shall apply except for
         quantity, description, and delivery schedule terms. Notwithstanding
         anything herein to the contrary, the parties intend that any agreement
         between the parties not otherwise identified herein not related to the
         Vendor status shall continue unaffected by this Agreement.

(b)      This Agreement shall not be modified or amended except by a writing
         signed by the parties to be charged, and no changes or additions to
         this Agreement shall be binding upon Lucent unless signed by an
         authorized representative of Lucent.

(c)      Both parties acknowledge they are sophisticated business entities with
         access to legal and financial counsel of their choosing and that each
         has had the opportunity to comment
