restriction and those commitments already in existence between Davox and other

     D.  EXCLUSIVITY.  Subject to this Section, during the Term (or any mutually
         -----------                                                            
agreed upon extension thereof) of this Agreement, and provided that Section l(d)
has not been terminated by Davox, both parties mutually agree that neither party
will enter into a distribution or reseller contract/arrangement with any direct

("Competitors") of each party:

<TABLE>
<CAPTION>
     Davox:                             Lucent:
     --------------------------------------------------------------------------
<S>                                <C>
     Mosaix Industries (formerly DSI)   Nortel
     Melita International               Rockwell International
     Versatility, Inc.                  Aspect Telecommunications, Inc.
     Syntellect, Inc.
</TABLE>

     This Section 1 shall apply only to Distributor's Business Communications
     Systems Division, and notwithstanding the foregoing, this Section shall not
     apply to any existing distributor/reseller arrangements, agreements or
     relationships of either Davox or Distributor's Business Communications
     Systems Division, and both parties agree to provide a detailed listing, at
     the commencement of this Agreement, specifying all Competitors that are, at
     that time, under the terms and conditions of a distributor/reseller
     contract with either party.  Nothing herein shall require either party to
     terminate said relationship(s) as provided in said listing.  Additionally,
     any information on the foregoing listing shall be deemed confidential
     information under the provisions of Section 10 and shall be maintained as
     provided under the provisions of Section 10.

     Nothing contained in this Section 1(d) shall be construed to restrict an
independent distributor of either Davox or Distributor from being a distributor
of a named Competitor's products, provided such arrangement is not used by Davox
or Distributor as a vehicle by which to circumvent the intent of this Section's
terms and conditions.  Furthermore, notwithstanding anything contained in this
Section l(d) and in Section 3(l) to the contrary, both parties agree that each
party shall have the right to enter into prime-sub relationships with any third
parties, including but not limited to Competitors, or to take any other similar
actions in order to meet individual customer needs or requirements, but neither
party shall use such prime-sub relationships or actions as a means to enter into
a relationship that is, in essence, a distributor/reseller arrangement with the
other party's Competitors.

     E.  DISTRIBUTOR CERTIFICATIONS.  Distributor hereby certifies and agrees
         --------------------------                                          
that, in consideration of the benefits of this Agreement, including the prices
granted to Distributor with respect to the Products that it may procure from
Davox:

                                      -2-
<PAGE>
 
     Distributor will market the Product(s) for its own account in the normal
     course of its business solely to end-users or Distributor's distributors
     ("Sub-Distributor(s)).  Notwithstanding the foregoing, in the event a Sub-
     Distributor will market and distribute the Products, Distributor and Sub-
     Distributor will both agree that prior to any marketing of the Products or
     sale/licensing of the Products by or through said Sub-Distributor, Davox
     must provide its written consent and approval for such appointment of said
     Sub-Distributor.  Additionally, any Sub-Distributor must agree to comply
     with all of the terms and conditions hereunder, with the exception of
     Sections l(d) and 3(l).  In the event that any of the foregoing
     undertakings are not complied with at any time during the term of this
     Agreement, Davox shall have the right to terminate this Agreement as to any
     or all further shipments to end users and as to any or all further exercise
     by Distributor of the rights granted herein with respect to the Products.

     F.  GRANT OF RIGHTS.  Subject to the terms and conditions of this
         ---------------                                              
Agreement, Distributor is hereby granted a non-exclusive, subject to Section
l(d), nontransferable right and license to take the following actions:

     1.   Market, distribute, sell, lease, and/or license the Product(s) to end-
          users in accordance with one of the programs listed in Section 2
          "Distribution Programs", and in accordance with the following:

          a.   Unless otherwise mutually agreed upon in writing, Distributor
               shall have the right and authority to distribute, in accordance
               with this Agreement, the Products to any site or location of a
               Davox customer, whether or not there is Distributor Equipment
               attached directly to the Products, provided:

               i.   Such distribution will be under the Prime-Sub Program and
               shall at all times be handled in accordance with the terms and
               provisions of a Prime-Sub transaction, unless otherwise agreed in
               writing between the parties hereto;

               ii.  Nothing contained above shall provide the right or authority
               for Distributor to provide or distribute any add on or upgrade
               Product(s), or Services thereto, to an existing Davox customer
               that has Davox products installed at that site.  Notwithstanding
               the foregoing, in the event a customer demands in writing that
               Distributor distribute the Products to said customer, Davox
               hereby consents to such distribution in accordance with this
               Agreement;

               iii. At all times, Distributor cannot provide or distribute any
               Product(s), or Services thereto, to those key accounts as
               identified in Exhibit 1, which shall be updated on a quarterly
               basis.  Beyond the initial listing of key accounts, additions to
               the key account list shall be made on a quarterly basis, and key
               accounts will be those customers as so designated in Davox's
               sales channel as "Key Accounts", provided said Key Account has
               Davox equipment or software installed at the time of the Key
               Account's addition to the list, but customers listed on the
               updated listing 

                                      -3-
<PAGE>
 
               that currently have installed Lucent PBX/ACD equipment, shall not
               be considered a Key Account, unless both parties mutually agree
               in writing. Notwithstanding the foregoing, in the event a Key
               Account demands in writing that Distributor distribute the
               Products to said Key Account, Davox hereby consents to such
               distribution in accordance with this Agreement.

     2.   Refer potential customers to Davox in accordance with Section 2B's
          provisions.

     3.   Use and display the Demonstration Product (as defined in Section 3c)
          for the sole purpose of promoting, marketing, and demonstrating the
          Product(s) in connection with the potential sale/licensing of
          Products.  Distributor has the right to purchase/license a maximum of
          fifteen (15) Demonstration Product, all at the prices and costs per
          Demonstration Product as described in Exhibit 1.  Subject to (i)
          Distributor paying to Davox the cost established in Exhibit 1, and
          (ii) availability of Demonstration Product and Davox's ability to
          provide Demonstration Product, Distributor may elect to increase the
          number of Demonstration Product purchased/licensed, but the number of
          Demonstration Product shall not exceed 25 Demonstration Product in
          total.

     4.   Within ninety (90) days after the execution of this Agreement, Davox
          will place and maintain in escrow with an independent third party
          escrow agent (the "Escrow Agent") acceptable to Distributor under the
          terms of an agreement with the Escrow Agent that is acceptable to both
          Davox and Distributor, a fully documented, current version of the
          source code to Davox's proprietary Software and the object code form
          of Sybase, which is made a part of the Products) provided hereunder
          (the "Escrowed Materials").  Notwithstanding the foregoing, Davox will
          provide updated Escrowed Materials to the Escrow Agent within thirty
          (30) days from Davox's general release of the machine-readable object
          code version of the Product(s) to the public.  In the event that Davox
          goes out of business or ceases to do business in the normal course as
          a going concern, or Davox is unwilling or unable to provide Services
          hereunder, or Davox is in material breach of the provisions of Exhibit
          4A or Exhibit 4C, or Davox fails materially to meet the Davox approved
          warranty obligations to the end user, and said material breach is not
          cured within fifteen (15) days of Distributor's notification to Davox
          of such breach, Distributor shall be entitled to gain access to the
          Escrowed Materials for the purposes of providing Services to its end
          user customers and subject to terms set forth herein and in the escrow
          agreement, attached hereto as Exhibit 5.  Notwithstanding the
          foregoing, Distributor shall have the right to make modifications to
          the Escrowed Materials to effectuate said maintenance services,
          provided that Davox shall retain all intellectual property rights in
          and to the Escrowed Materials and any modifications or derivatives
          thereto.

                                      -4-
<PAGE>
 
          In the event that Distributor rightfully gains access to the Escrowed
          Materials under the terms of this Section, Davox grants to Distributor
          a non-exclusive, non-transferable license to use the Escrowed
          Materials solely in accordance with the terms and conditions herein
          and under the escrow agreement.  In the event this Agreement is no
          longer in existence, Distributor shall have a limited use right solely
          to maintain the Products, provided the non-disclosure and license
          terms herein are complied with.  Distributor acknowledges that the
          Escrowed Materials contain confidential information.  Distributor
          agrees to take such steps as may be necessary to prevent the Escrowed
          Materials from being used by or disclosed to any person or entity
          other than its employees or contractors in the course of their
          employment for purposes not inconsistent with the terms of this
          Section.  Anything herein to the contrary notwithstanding, all right,
          title and interest in and to the Escrowed Materials shall remain
          vested in Davox.

          Davox's obligations and Distributor's rights under this Section
          l(f)(4) shall terminate upon the earlier to occur of (i) Distributor's
          breach which directly leads to termination or cancellation of this
          Agreement, or (ii) default by Distributor of its obligations under
          this Agreement, which such default continues for thirty (30) days
          after written notice thereof from Davox to Distributor. Upon
          termination of Davox's obligations under this Section, Distributor
          shall immediately discontinue use of all Escrowed Materials and return
          Escrowed Materials to Davox.

          Davox agrees that the release terms herein shall form a part of the
          independent escrow agent's release terms, and Davox agrees that it
          will execute the necessary paperwork to effectuate this result.

          Distributor shall pay all direct, incremental fees and expenses
          related to said escrow account.

     G.   CANADA.  The parties acknowledge that Distributor may distribute
          ------                                                          
          Products in Canada through its subsidiary Lucent Technologies Canada
          Inc.  For purposes of this Agreement, Distributor shall encompass
          Lucent Technologies Canada Inc. in every instance where the Agreement
          applies to Distributor activities, rights, duties, obligations and
          liabilities in or relating to transactions in Canada.

2. DISTRIBUTION PROGRAMS:
   --------------------- 

     A.   Prime-Sub Contractor (Prime-Sub)
     -------------------------------------

          Under this Prime/Sub Program, Distributor will have primary
     responsibility for selling and closing the customer account and will
     contract the Product(s), Implementation Services, and Training Services on
     Distributor agreements (both purchase/license). Notwithstanding the
     foregoing, Distributor and Davox may mutually agree in writing that
     Implementation Services and Training Services should be contracted directly
     from the Customer to Davox. At all times under this Program, Maintenance

                                      -5-
<PAGE>
 
     Services shall be contracted directly between Davox and the end user
     customer under Davox's standard Continuum Support Services Agreement terms
     and conditions (See Exhibit 4A). Distributor may contract for Maintenance
     Services with the end user customer, but provision of Maintenance Services
     must be subcontracted directly with Davox. The governing terms and
     conditions for Davox's provision of Maintenance Services to the end user
     customer shall be Davox's standard Continuum Support Services Agreement,
     unless otherwise agreed in writing by Davox in its sole discretion. Davox
     will assist the Distributor sales organization with the close of the
     transaction and, all the Implementation, and Training Services will be sub-
     contracted to Davox under a Distributor Purchase Order(s) or the customer
     specific Prime-Sub agreements, which shall be negotiated between the
     parties in good faith ("Prime-Sub Agreement"). Distributor shall have the
     right to approve of or disapprove Davox's use of any subcontractors other
     than Grumman System Support Corp., but such approval shall not be
     unreasonably withheld. The pricing for the Products that Distributor shall
     pay to Davox is as defined in Exhibit 1 and the prices and fees for
     Services shall be as defined in Exhibits 2, 4, and 9.

     B.  Referral Program
     --------------------

         This program will support those instances in which Distributor in its
     sole discretion does not sell, or wishes not to sell directly to the end
     user. Davox will pay a finders fee of 5% of the total net sales price of
     the Davox proprietary Product(s), excluding any discounts and costs for
     service, implementation, training and taxes, shipment, freight, and
     insurance to Distributor. Under this Referral Program, the total
     transaction will be sold and supported by Davox and will be credited
     towards the Minimum Revenue Performance Level as outlined in Section 3(i).
     The following procedure shall be followed for this Program:

          i)   To qualify, the lead must be a minimum configuration of 20 seats
          and be qualified to close within 180 days.

          ii)  Distributor must identify the opportunity through the completion
          of a Lead Registration Form to the Manager, Business Partners at
          Davox.  The Lead Generation Form's appearance and content will be
          mutually agreed upon between the parties.

          iii) Davox shall review the lead and upon identifying the lead as a
          "new" opportunity, will accept the lead and return the signed form to
          Distributor.  A lead is not considered "new", when the prospect/lead
          is being worked directly/indirectly by Davox's sales force or is
          currently a Davox customer.  Davox must notify Distributor within five
          (5) days of receipt of a Lead Registration Form as to acceptance or
          non-acceptance of said Lead.

          iv)  This Lead Registration Form, if accepted and executed by Davox,
          will qualify Distributor for the 5% Finders Fee (as described above),
          which will be paid, net thirty (30) days from the Davox's shipment
          date to the end user customer.

                                      -6-
<PAGE>
 
          v)  The Finders Fee will be paid only once per customer on the initial
          sale/licensing to a customer only.

3.   DISTRIBUTOR'S OBLIGATIONS
     -------------------------

     A.  REASONABLE EFFORTS.  Distributor will use such efforts as are
         ------------------                                           
commercially reasonable to (i) promote, solicit and obtain orders for the

reputation of Davox.  Distributor represents that it possesses the experience,
skills and resources required to carry out these marketing activities.

     B.  FACILITIES AND STAFF.  Davox recommends that Distributor possess and
         --------------------                                                
maintain facilities and staff that will allow it to effectively market the
Products throughout the Territory.  It is required that Distributor establish
and implement appropriate training programs for its staff

     C.  DEMONSTRATION PRODUCT.  Distributor will order from Davox the Products
         ---------------------                                                 
specified in Exhibit 1, and defined as demonstration product (the "Demonstration
Product") in accordance with the terms contemplated in this Agreement.
Distributor will not sublicense, assign, allow third party use of, or act as a
service bureau, or otherwise transfer the Demonstration Product to any person
without Davox's prior written approval.

     At all times, following the initial training as described in Section 4(d),
it shall be Distributor's responsibility to install and maintain all
Demonstration System(s) and updates thereto, itself.

     D.  PROMOTION.  Distributor will, at its expense, actively promote and
         ---------                                                         
advertise the Products and will take some or all of the following actions or
take such other activities which will, in Distributor's good faith belief,
result in comparable market impact:  (i) placing the Products in Distributor's
catalogs; (ii) featuring the Products in any applicable trade show that it
attends and (iii) contacting existing and potential customers on a regular basis
to solicit orders for the Products, consistent with good business practice.

     E.  MARKETING MATERIALS/PRODUCT DOCUMENTATION.  Distributor may use the
         -----------------------------------------                          
Marketing Materials and Product Documentation, described in Exhibit 6, which
shall describe the Products in the English language.  Distributor may reproduce,
but not modify, only the Collateral Materials as described in Exhibit 6 for
distribution within the Territory.  Distributor will affix Davox's copyright and
trademark notices to all such reproductions, and shall not deface or remove such
notices.  Distributor will bear all reproduction costs, unless otherwise agreed.
In the event Distributor desires to modify, in any way, or affix its corporate
name and logo (alongside Davox's) to said Collateral Material, Distributor must
provide a sample to Davox and receive Davox's prior written consent, which shall
be in Davox's sole discretion prior to any use.

     F.  SOFTWARE.  Distributor will promote, solicit and accept orders for the
         --------                                                              
Software subject to the terms and conditions contained herein.  In accordance
with Davox's commitments to its third party licensors, Davox may modify the
procedures and terms for licensing herein upon 

                                      -7-
<PAGE>
 
thirty (30) days advance written notice to Distributor, in whole or in part,
subject to any binding commitment that Davox has made to Distributor. Until
further notice, Distributor will utilize the agreements and procedures set forth
below for the respective items of Software. In no event will Distributor license
or deliver to any customer or third person any source code for the Software, in
whole or in part.

     (i)  Distributor will promote, solicit and accept orders for the DCS
          operating system software incorporated into each item of Davox
          Hardware subject to the terms and conditions of the "shrink-wrap"
          license contained in the respective Hardware package.  Distributor
          will notify each purchaser of an item of Hardware that the respective
          package contains a "shrink-wrap" license.

     (ii) Distributor will promote, solicit and accept orders for the Software
          identified in Exhibit 1 as the Base System, Desktop API Developer
          License, SCALE, software included in the DCS, and Additional
          Supervisor Licenses, (hereinafter referred to as: "Davox Licensed
          Software") subject to the terms contained in the software license
          agreement attached hereto as Exhibit 3 (the "Software License").
          Davox may modify or replace the Software License, at any time, in
          whole or in part, with thirty (30) day prior written notice to
          Distributor and consent to said changes from Distributor, which
          consent shall not be unreasonably withheld.  Distributor may utilize
          its own license agreement to cover use of Product(s) provided its
          terms and conditions are substantially similar to those in the
          Software License and Davox provides its written consent to such
          license prior to Distributor's use, which consent will be contingent
          upon Davox receiving consent from its third party licensors ("Approved
          License").  Distributor agrees that every time Software is licensed
          pursuant to this Agreement (whether by original license, expansion or
          upgrade), Distributor shall obtain written agreement from its end user
          that the Software License or the Approved License terms and conditions
          shall govern the terms of the licensing to said end user.  In the
          event Distributor fails to secure such written agreement from its end
          users and/or Davox approved sub-distributors, Distributor agrees to
          indemnify Davox to the full extent for any damages that Davox incurs
          solely due to Distributor's failure to obtain said agreement. (BOTH
          PARTIES SPECIFICALLY AGREE THAT THIS INDEMNITY SHALL NOT BE SUBJECT TO
          OR LIMITED BY SECTION 9'S LIMITATION OF LIABILITY).

     G.   SERVICES.  (i) Maintenance services shall be furnished to end user
          ---------                                                         
customers that purchase/license Products under the terms of this Agreement,
directly from Davox and Davox's hardware support subcontractor, Grumman System
Support Corp. in accordance with the terms, conditions and pricing of Davox's
standard Continuum Support Services Program, or under the terms, conditions and
pricing negotiated between Distributor or Davox and the end user customer,
provided Davox has provided its written consent.  Exhibit 4A shall define the
Maintenance Services to be provided to an end user customer, Exhibit 4B shall
define the spare parts pricing for Davox hardware components, Exhibit 4C shall
define the escalation procedure utilized by Davox, and Exhibit 4D shall define
the prices and fees that Davox shall receive for 

                                      -8-
<PAGE>
 
such Maintenance Services. Davox warrants that all Services provided hereunder
will be rendered in a professional and workmanlike manner consistent with
industry practice. Distributor is not authorized, nor does it have the right to
perform any Maintenance Services on Product. (ii) Unless otherwise agreed upon
in writing, provision of Training and Implementation Services shall be
subcontracted from Distributor to Davox, in accordance with the Implementation
Plan attached hereto as Exhibit 9A and the pricing thereto shall be as defined
in Exhibit 9B.

     H.  PRICES.  Distributor will independently establish the prices that it
         ------                                                              
charges to customers within the Territory for the Products and related
Implementation and Training Services, but shall at all times pay to Davox the
fees and prices contained in this Agreement.  Distributor will be solely
responsible for obtaining payment of its prices from customers.  Delays or
failures in obtaining such payments will not affect Distributor's obligation to
make payments to Davox pursuant to Section 6.

     I.  MINIMUM REVENUE PERFORMANCE LEVEL.  In the event the following Minimum
         ---------------------------------                                     
Revenue Performance Levels are not attained by Distributor, Davox may terminate
the exclusivity provisions contained under Section 1(d):

marketing activities under this Agreement, including (i) a current list of
customers licensed to use the Products and (ii) copies of all Software Licenses
or Approved Licenses executed with customers.  Distributor will provide Davox
with a rolling 3-month order forecast commencing on the first day of the next
month including details of prospective orders by Product model, quantity, net
forecasted fees to Davox, intended order submittal dates and desired delivery
dates.  Distributor will also provide such other reports that Davox may
periodically request, and agreed upon between the parties.

     K.  ENFORCEMENT.  Distributor will effectively enforce against all of its
         -----------                                                          
end user customers that obtained the Products from Distributor the Software
License that affects proprietary or confidentiality rights of Davox or its
licensors in the Products.  If Distributor learns that any customer has breached
any such provision, Distributor will immediately notify Davox and take, at
Distributor's expense, all steps that may be available to enforce the Software
License, including availing itself of actions for seizure or injunctive relief.
If Distributor fails to take these steps in a timely and adequate manner, Davox
or its licensors may take them in its own or Distributor's name and at
Distributor's expense.

     L.  NON-COMPETITION.  During the Term of this Agreement, and subject to
         ---------------                                                    
Section l(d)'s exclusivity provision being in effect pursuant to Section 3(i),

been disclosed to Distributor at the time of the execution of this Agreement.
Thereafter, as products are added to the list of Products, both parties will
mutually agree in writing as to whether or not said additional products will be
subject to the terms of this Section 3(l).  Davox agrees that, during the term
of this Agreement, it will not distribute an Automatic Call Distributor ("ACD").

4.   DAVOX'S OBLIGATIONS
     -------------------

     A.  MARKETING MATERIALS.  Davox will provide Distributor with access and
         -------------------

the Demonstration Systems.  Following said training, it will be the
responsibility for Distributor to install and maintain all Demonstration
Systems.  Any Services performed, other than the initial training, shall be on a
time and materials basis.  Davox will provide updates to the Demonstration
Product within thirty (30) days from the date that Davox provides said updates
to its own sales force, provided Distributor pays any out of pocket cost that
Davox may reasonably incur relating to installation, maintenance, or shipment.

     E.  PRODUCT INFORMATIONAL MEETINGS.  Subject to Section 10's
         ------------------------------                          
confidentiality provisions, Davox will provide to Distributor a summary of its
planned future product releases, no less than two times per year.  At that time,
both parties will mutually agree whether Distributor will have the right to
distribute such new products and any terms related thereto.  Nothing contained
in any report provided to Distributor shall be construed as a commitment to
provide any products in the time frames specified, nor is Davox committing to
bringing any product listed on such report to market.  ANY REPORT IS SOLELY
PROVIDED TO DISTRIBUTOR FOR INFORMATIONAL PURPOSES AND IS NOT MEANT AS A
COMMITMENT OF ANY KIND.

5.   ORDERS AND DELIVERY
     -------------------

     A.   PRIME-SUB.  Distributor will place orders for the Products under the
          ---------                                                           
Prime - Sub Program directly with Davox in the following manner:

                                      -10-
<PAGE>
 
          (i) Distributor must submit to Davox the Software License or the
          Approved License, executed by both Distributor and its end user, along
          with a Purchase Order or Prime - Sub Agreement referencing this
          Agreement as "LUC-1997", specifying the Products and Services, the
          specific Product configuration, customer name, personnel contact
          names, and location, anticipated delivery dates, and any and all other
          information Davox may reasonably request to effectuate a smooth
          implementation of said end user;

          (ii) Each order should, but does not necessarily have to, include an
          executed standard Davox Continuum Support Services Agreement signed by
          the end user customer, and at Davox's standard rates and fees for
          Maintenance Services.  Distributor will use commercially reasonable
          efforts to obtain such agreement.  Both parties mutually understand
          and agree that in the event any customer has not executed a standard,
          or negotiated, Continuum Support Services Agreement with Davox, prior
          to the conclusion of said end user's warranty period, Services shall
          be provided to the end user customer thereafter on a time and
          materials basis.  Davox agrees that it will pay to Distributor a 2%
          commission on any standard Continuum Support Services Agreement
          executed by an end user customer that Davox receives with or prior to
          the conclusion of the ninety (90) day warranty period referenced in
          Section 7, and for which Davox personnel had no active sales/marketing
          involvement.  Commissions in the preceding sub-clause (i) shall be
          based upon the initial Continuum Support Services fee paid by the end
          user to Davox.  Said fee shall be paid to Lucent net thirty (30) days
          from receipt of the standard Continuum Support Services Agreement;

          (iii) Each order must include the minimum statement of work and
          software specification information as more particularly described in
          Exhibit 9B.

     C.   EXPANSION ORDERS.  In addition to the other provisions in this Section
          ----------------                                                      
5, expansion orders of Product under this Agreement for end users shall be
handled in the following manner:

          Expansion Orders are those orders that flow from a Distributor initial
          customer purchase/license of product (for example, upgrades, add on
          orders, etc.).  Distributor must receive a binding purchase order
          form, or its equivalent ("PO") from the end user customer specifically
          referencing the Software License or Approved License between itself
          and Distributor ("PO Reference").  In addition to the language
          required to effectuate the terms of this Agreement, said PO Reference
          must provide that the Products provided under the PO shall be governed
          by said Software License or Approved License.  Additionally, all
          Expansion Orders for Products should, but not necessarily have to,
          include a separate PO with regard to Maintenance Services for the
          particular Product.  Davox will bill the end user customer for the
          additional services required.  In the event Distributor (or any Davox
          approved sub-distributor) does not adhere to the terms herein and
          Davox 

                                      -11-
<PAGE>
 
          incurs any damage due to such failure to adhere to the terms herein,
          Distributor shall indemnify Davox for any and all losses incurred by
          Davox due to such failure. (BOTH PARTIES SPECIFICALLY AGREE THAT TIES
          INDEMNITY SHALL NOT BE SUBJECT TO OR LIMITED BY SECTION 9'S LIMITATION
          OF LIABILITY.)

     D.   ACCEPTANCE. Davox may accept or reject any order under the Prime - Sub
          ----------
Program and any lead referral under the Referral Program in its sole discretion,
subject to any binding commitment that Davox has made to Distributor. Davox may,
in its sole discretion, allocate available inventory among its customers in any
manner that Davox deems fair and reasonable. No order under the Prime-Sub or
Referral Programs will be deemed accepted unless Davox confirms its acceptance
in writing. Davox will use its reasonable efforts to respond to each order
within 5 days after its receipt from Distributor. Any order that Davox may
accept will be subject to the terms and conditions of this Agreement.

     E.   SHIPMENT.  Davox will establish a shipment schedule for each order
          --------                                                          
accepted from Distributor.  Notwithstanding the foregoing, and unless otherwise
agreed by Davox, Davox will endeavor to install Products within ninety (90) days
from Davox's receipt and acceptance of the Order.  Davox will ship the Products
from its distribution center in accordance with this schedule, subject to delays
beyond Davox's reasonable control.

     F.   RESCHEDULING.  Under the Prime - Sub Program, Distributor may
          ------------                                                 
reschedule a shipment date for the Products by notifying Davox of the proposed
new shipment date, but any such proposed new date cannot extend the original
shipment date by more than thirty (30) days.  If Davox receives a rescheduling
notice at least thirty (30) days before the original shipment date, the
rescheduling will not be subject to additional charges.  If Davox receives the
rescheduling notice thirty (30) days or less before the original shipment date,
then Distributor will pay to Davox an amount equal to 5% of the price of the
Products included in the rescheduled order.  A shipment date may not be
rescheduled more than once.

     G.   DELIVERY.  Any Products that Davox ships to Distributor and has not
          --------

Davox's facility in Westford, Massachusetts, freight pre-paid and add, with
freight/shipment charges payable by Distributor to Davox.  All shipments to
Distributor's end users shall be FOB Davox's facility in Westford,

Distributor or Distributor's end user at the time it leaves Davox's distribution
center.  Notwithstanding the foregoing, Distributor shall provide, upon request
of Davox, a "purchase money security interest" in said Products to secure
payment.  Under these circumstances, the Distributor will, at the request of
Davox, execute and register the instruments required to perfect said security
interest.  Distributor acknowledges that title to the Software will not, under
any circumstances, pass to Distributor or its end user customers.

notify Davox of any breakage, tampering, shortage or other discrepancy between
the Products and shipping documents.  Distributor, or its end user customer will

8.  INDEMNITY BY DAVOX
    ------------------

     A.  INDEMNITY.  If an action is brought against Distributor claiming that

Software and replace or modify said infringing Davox Hardware or Software with a
non-infringing equivalent, procure the right to continue using the Davox
Hardware or Software, or accept the return of the Davox Hardware or Software in
exchange for a refund of the price that Distributor actually paid to Davox for
such Davox Hardware or Software, less depreciation based on a 5-year straight-
line depreciation schedule.

modification, or Derivative of the Davox Software not provided by or approved in
writing by Davox, (ii) the failure to promptly install a Fix, update or
enhancement of the Davox Software that would have eliminated the actual or
alleged infringement or (iii) the combination of the Davox Software with other

unauthorized use or disclosure of the Information may cause irreparable damage
to the other party or its licensors.  If an unauthorized use or disclosure
occurs, the party disclosing the Information ("Breaching Party") will promptly
notify the other party ("Aggrieved Party") and take, at the Breaching Party's
expense, all steps which are necessary to recover the Information and to prevent
its subsequent unauthorized use or dissemination, including availing itself of
actions for seizure and injunctive relief.  If the Breaching Party fails to take
these steps in a timely and adequate manner, the Aggrieved Party may take them
in its own or the Breaching Party's name and at the Breaching Party's expense.

words, phrases or symbols identifying the Products or Davox's business (the
"Marks") are and will remain the exclusive property  of Davox or its licensors,
whether or not specifically recognized or perfected under the laws of the
Territory.  Distributor will not take any action that jeopardizes Davox's or its
licensors' proprietary rights or acquire any right in the Marks, except the
limited use rights specified in Section 11(b).  Distributor will not register,
directly or indirectly, any trademark, service mark, trade name, copyright,
company name or other proprietary or commercial right which is identical or
confusingly similar to the Marks or which constitute translations thereof into
the language(s) spoken within the Territory.  Upon Davox's request, Distributor
will execute the instruments that may be appropriate to register, maintain or
renew the registration of the Marks in Davox's or its licensors name within the
Territory.  Notwithstanding the foregoing, all of Distributor's trademarks,
service marks, trade names, logos or other words or symbols ("Distributor
Marks") are and will remain the exclusive property of Distributor or its

the sole benefit of Davox.  All advertisements and promotional materials will
(i) clearly identify Davox or its licensors as the owner of the Marks, (ii)
conform to Davox's then-current trademark and logo guidelines and (iii)
otherwise comply with any local notice or marking requirement contemplated under
the laws of the Territory.  Before publishing or disseminating any advertisement
or promotional materials bearing a Mark, Distributor will deliver a sample of
the advertisement or promotional materials to Davox for prior approval.  If
Davox notifies Distributor that the use of the Mark is inappropriate,
Distributor will not publish or otherwise disseminate the advertisement or
promotional materials until they have been modified to Davox's reasonable
satisfaction.  Notwithstanding the foregoing, provided Davox has provided its
written consent, Distributor will have the fight to place the Distributor Marks
alongside Davox's Marks, but such consent may not be unreasonably withheld.

     C.  INFRINGEMENT.  Distributor will immediately notify Davox if Distributor
         ------------

Davox may reasonably request and (ii) take no steps on its own without Davox's
prior approval.

          for its business or assets, or avails itself of or becomes subject to
          any other judicial or administrative proceeding that relates to
          insolvency or protection of creditors' rights.

                           1. A. PRODUCT DESCRIPTION

The following describes the five (5) components of the Davox Unison Call Center
Management System.  Attached hereto Exhibit 1-D is a Sun Hardware listing that
provides the Sun Microsystems's requirements that Lucent shall procure on its
o___ to run the following components of the Davox Unison Call Center Management
System.  Only those items listed in paragraph #1 below shall be considered the
base product ("Base Product").

1.  Unison Call Management Software (Base System)
    --------------------------------------------

Davox's Unison systems include supervisor management tools utilizing Rules-Based
management strategies and a broad range of software-driven features that allow
the real-time control of all call center activities via a user-friendly, point-
ar__ click graphical user interface (GUI).

The Unison Call Center Management System software is comprised of three (3)
modules, each with a distinct set of features designed to enhance calling
operations, resulting in improved supervisor, agent, and overall call center
productivity.

    .  Unison Strategist(R) -- Allows call center managers to set overall
       productivity objectives and campaign strategies for the call center in a
       timely fashion. Features of this module support supervisory tasks for
       establishing and managing all center activities, including messaging,
       scripting, and reporting, all via an easy-to-use graphical user
       interface. Most importantly, all user-defined parameters can be modified
       at any time to reflect shifts in strategic objectives.

    .  Unison Tactician(R) -- Provides supervisors the flexibility and
       functionality to ensure maximum agent productivity and effectiveness. By
       providing real-time "windows" into all call center activity, supervisors
       can measure both individual and team performance and when necessary,
       quickly and easily spot and support individuals requiring assistance.
       With outbound agent skill set matching and transfer capabilities, users
       can be assured that customer calls are handled by the appropriately
       skilled agent or agent group. Real-time monitors assist supervisors in
       tracking and reacting to changing conditions which might adversely affect
       operations.

    .  Unison Precision Dial(R) -- Automates all aspects of the calling process
       by streamlining unproductive, time consuming, and redundant tasks,
       allowing agents to focus on the customer contact and supervisors to
       assist agents in their efforts. Agents are paced seamlessly and
       automatically through the calling tasks and jobs, including those
       scheduled to occur at a time and date in the future. Inbound calls
       received prior to a scheduled outbound placement are eliminated from the
       calling job, while newly scheduled customer contacts are automatically
       inserted into an appropriate call campaign. By offloading all call
       placement activities, agents and supervisors are free to engage in and
       focus on productive customer conversations.
<PAGE>
 
2.  Desktop API Developer License
    -----------------------------

The agent's desktop application will vary significantly depending upon the
individual end user.  Unison provides an Application Programming Interface
("API"), that allows the application provider with the necessary message set in
order to integrate their desktop application with the Unison Base Product to
provide a seamless integration.

3.  Seamless Call and Agent Load Equalizer (SCALE)
    ---------------------------------------------

The SCALE(R) option allows users to create pools of agents which can alternate
between handling incoming and outgoing calls as overall peak and lull patterns
dictate.  In so doing, Unison allows call center management to share valuable
agent resources for call handling and call placement functions.  SCALE, which
monitors inbound activity via an ASAI CTI link to the AT&T G3, provides the
seamless blending of outbound and inbound calling functions.  Based on dynamic
checks of the inbound queue-dependent, user-defined threshold settings or
service level goals, blended agents are Assigned inbound calls as necessary to
maintain the established goal settings.

All inbound activity is reported on in the same manner as outbound calling
activity: agent status displays, agent and campaign call results, agent and
campaign alerts, etc.

Supervisors control outbound and inbound agent assignments as well as set agent
priority assignments for each campaign worked.  This provides for ultimate
flexibility in defining which agents Unison should seek first for any campaign,
outbound or inbound.  Adjustments can be made as necessary as conditions
dictate, without interrupting campaign activity.

SCALE coupled with the Unison Call Center Management Base software ensures
ultimate productivity in the call center by streamlining and maximizing all call
center resources.

4.  Digital Communications Server (DCS)
    -----------------------------------

The Unison DCS is a fully digital, non-blocking switch matrix, with direct T1
support for both trunk and agent connections.  The DCS places calls via PBX/CO
trunks and performs call signal detection, call progress analysis, and call
routing functions.  The DCS, incorporating advanced digital signal processing
(DSP) technology, is based on the industry standard SPOX operating system
developed at Massachusetts Institute of Technology (MIT).

Each physical DCS cabinet supports a total of 288 voice ports.  A voice port can
be configured either for support of outbound call processing or as an agent
interface.  The non-blocking, digital switch is designed to interconnect with
other Digital Communications Servers to form a scaleable, non-blocking matrix of
up to 200 outbound/blended agents and 300 lines.  All components are VME
compatible.

                                      -30-
<PAGE>
 
Depending upon the customer environment and requirements, the Unison base
software module can interface either to the DCS as described above or to the
AT&T G3 Call Classifier option to perform call signal detection and call
progress analysis.

5.  Additional Supervisor License
    -----------------------------

Each Unison Base Product comes with one (1) Supervisor License.  For larger
Systems, additional Supervisor Licenses may be required to allow a division of
agents into groups where each supervisor can view and mange their individual
groups.  Refer to Exhibit 1.D. for workstation options to provide these
additional supervisory positions.

     Davox reserves the right, at any time, to evaluate any Equipment or
     Software, including its use and environment, and qualify continuance of
     support services based upon changes, which, in Davox's sole opinion, are
     reasonably required for the proper operation of any Equipment, Software and
     the continuance of the Support Option in effect hereunder.

7.  PAYMENT

     In return for the Services under the Support Option(s) or other coverage to
     be provided, Customer agrees to pay to Davox the fees stated on the
     Quotation or such fees as Davox may, from time to time, establish in
     accordance with this Section prior to the commencement date of each term or
     as otherwise provided in this Agreement.  Davox may change the prices for
     Support Options by providing Customer written notification of such changes
     ninety (90) days prior to the end of a current term.  The fees stated are
     annual charges, quoted and to be paid in United States dollars, and shall
     be paid one (1) year in advance.  Davox shall invoice Customer annually,
     not more than sixty (60) days prior to the commencement of the Initial Term
     or the expiration of the then current Term and such invoice will be due
     upon receipt.  Support services furnished on a "time and material" basis
     will be invoiced as rendered and shall be due thirty (30) days from the
     date of invoice.

     Davox may suspend or terminate, at its sole option, this Agreement in the
     event Customer fails to make prompt payment on or before the invoice due
     date or if Customer otherwise materially breaches this Agreement.

     With the exception of United States income taxes which Davox may be
     obligated to pay as the result of payment made by Customer, Customer agrees
     to pay or reimburse Davox for all other taxes, duties, fees, and all other
     charges which may be levied by any governmental body as a result of this
     Agreement.  All amounts payable by Customer to Davox under this Agreement
     are exclusive of any tax, levy, or similar governmental charge that may be
     assessed by any jurisdiction, whether based on gross revenue, the delivery,
     use or possession of the Products, the execution or performance of this
     Agreement or otherwise, except for net income taxes assessed on Davox in
     the United States, by taxing authorities within the United States.  Subject
     to this exception, Customer shall pay all taxes, levies or similar
     governmental charges or provide Davox with a certificate of exemption
     acceptable to the taxing authority.  If Customer is required under the law
     of any applicable jurisdiction to deduct any withholding taxes from
     payments to Davox, then (i) Customer shall notify Davox prior to
     withholding any such taxes, (ii) the price payable by Customer for the
     products shall be increased so that the actual amount received by Davox,
     net of all taxes, will be equal to the prices set forth in the Agreement
     and invoiced Customer and (iii) Customer will promptly furnish Davox with
     the official receipt of payment of these taxes to the appropriate taxing
     authority.

     In the event Customer requests support services under a Support Option and
     the UNISON System is located at a site other than that shown as the Install
     Location in the Quotation, Davox shall have the right to charge Customer
     for travel time and reasonable travel expenses incurred as the result of
     such request to perform support hereunder at another site.

8.  UPDATES AND ENGINEERING CHANGES

     Updates and engineering changes will be made to the Equipment or Software
     when in Davox opinion such updates and changes are necessary to correct
     mechanical or operational errors or deficiencies in order to conform the
     Equipment or Software to Davox published specifications at the time of
     shipment.

     Davox may from time to time elect to make changes to the Equipment or
     Software to enhance performance, reliability, or serviceability and make
     such changes available to Customer.

     All updates and changes released by Davox under this subsection shall be
     deemed `Revisions".  Davox shall provide Customer with general Revisions of
     the Software upon release by Davox.  Davox will be relieved of any
     liability arising out of any errors or defects in any prior version or
     Revision of the Software ten (10) days following delivery of the latest
     Revision.  Customer may elect to install or not install a Revision.  In the
     event Customer elects not to install the latest Revision, Davox will
     continue to support the immediate prior Revision until the next new
     Revision is released.  In no event shall Davox be obligated to support a
     Revision other than the then latest Revision or, the immediate prior
     Revision.

     new site and environmental conditions as a condition for continuing Support
     on the UNISON System and to bill Customer at its then prevailing rates for
     such inspection and any labor, material and adjustments which, in Davox's

     UNISON System shall be to deinstall the UNISON System at Customer's then
     current location and re-install the UNISON System at Customers new
     location.  In the absence of prior shipping instructions, Davox will select
     a carrier on behalf of Customer, but in no event shall such carrier be
     construed to be an agent of Davox.  Risk of loss to the UNISON System shall
     at all times reside solely with Customer.  IN NO EVENT SHALL DAVOX 

                                      -77-

     not designed, unusual physical or electrical stress, accident, neglect,
     acts of God, or misuse, abuse, or modification of the Equipment or Software
     by persons other than Davox.  When support service is required for reasons
     other than normal wear and tear, services will be performed at Davox's then
     prevailing time and materials rate and an invoice issued to the Customer.
     If Customer modifies the Equipment or Software or adds foreign devices to
     the UNISON System, then Davox may at its option, (i) terminate this
     Agreement or (ii) support and service such modifications and foreign
     devices at its then prevailing rates.  Provisions or replacement of
     operational supplies or media items are specifically excluded from support
     services hereunder.

                          PROBLEM ESCALATION PROCEDURE


I.  INTRODUCTION
    ------------

     This procedure defines the process for handling and escalating problems on
     released products for customers with support contracts within DAVOX.  It
     describes how problem calls are placed, how problems are prioritized, how
     problems are escalated, and how higher levels of technical and management
     resources are brought to bear on especially difficult problems.

/*/ INDICATES MATERIAL THAT HAS BEEN OMITTED AND FOR WHICH CONFIDENTIAL
TREATMENT HAS BEEN REQUESTED. ALL SUCH OMITTED MATERIAL HAS BEEN FILED WITH THE
COMMISSION PURSUANT TO RULE 24b-2 PROMULGATED UNDER THE SECURITIES EXCHANGE ACT
OF 1934, AS AMENDED.

                                     -82-
<PAGE>
 
II.  PURPOSE
     -------

     To establish the lines of communications and to identify the responsible
     DAVOX personnel and/or ensure all calls are managed in a consistent and
     expeditious manner to minimize downtime and disruption to the customer
     environment.

III   GENERAL GUIDELINES
      ------------------

1)   All escalation begins within the Worldwide Support Center (WSC).

2)   The WSC representative who initiates a Case is responsible for ensuring
     problem resolution and communicating status and/or resolution to the
     customer.

3)   The WSC representative in conjunction with the customer assesses the
     technical and business impact of the problem and assigns the priority (see
     Case Priority Definitions "Attachment "A").  The priority of the escalated
     problem will be reviewed by WSC management.

4)   The status/resolution of an escalated problem is reported by the action
     owning department to the WSC, via the on-line system, for customer
     communication/verification and Case closure.

5)   Initial problem escalation is the responsibility of the WSC and is effected
     via a predetermined set of timeframes based upon the priority of the
     problem (Attachment "B").

6)   All problems escalated to Development will be accompanied by a Case/Defect
     with problem duplication (or agreed best effort performed).

7)   Problem escalation's to Development is from the Installation Support and
     SES organizations ONLY.

8)   Customer and/or field retrieval of required additional information,
     installation of available fix, and follow up remain the responsibility of
     SES/SIS department.  In circumstances where problem reproduction is not
     possible, the escalating department should be prepared to participate in
     the problem resolution activities as required to ensure a timely solution.

9)   ALL Customer system problems should be escalated through the established
     paths of the Installation Support and/or SES organizations regardless of
     priority and should be accompanied by the appropriate Defect/Case database
     information.  It is understood that any escalation's outside this process
     will occur when the time attributed to following these guidelines would, in
     and of itself, impose a significant delay or overall reduction in the
     service quality provided to the customer.

10)  If a patch or workaround supplied by Development does not solve the
     customers problem; SES/SIS is to escalate the problem back to Development
     where continuous effort (as required) will be applied to correct the
     problem.

                                      -83-
<PAGE>
 
11)  All times in this document are (MAXIMUM TIMES) to be viewed as "Stated
     Company Business Hours/Days" management reserves the right to move calls as
     required to meet specific business demands.

12)  If a Case is determined to be outside of the intended specified
     functionality of the product.  The Case will be escalated to Marketing for
     resolution with the customer in accordance with the priorities and time
     frames as stated herein.

IV   PROCEDURE
     ---------

1.0  INITIAL CUSTOMER CONTACT
     ------------------------

       The customer contacts the WSC with the nature of the problem and the
       pertinent information is entered into the on-line system (Support Center
       1-800-999-4455, International 508-952-0669).

 .      The WSC performs the necessary troubleshooting or diagnostics to
       establish corrective action and implementation.

   unless different priorities are assigned by Management.

VI.  ENHANCEMENTS
     ------------

 .  If a reported problem has been determined to be a product improvement or
   enhancement, then the Case will be forwarded by the WSC to the Marketing
   Department for evaluation.

 .  The Marketing Department will then:

     1.   Determine if it is to become a product improvement.  If so, the
          specification will be forwarded to Development.  If not, the issue
          will be closed through the WSC.

     2.   Determine if it is to be treated as a special and quoted to the
