                 1A.1     PURPOSE AND SCOPE OF THIS AGREEMENT.  The purpose of
this Agreement is to permit Supplier to provide and Ordering Company to receive
Supplier's Products, Licensed Materials, and Services.  This Agreement shall
govern all transactions pursuant to which Supplier provides Products, Licensed
Materials and Services to AT&T and Ordering Companies.  AT&T and Supplier will
develop a template no later than June 30, 1996 for use when AT&T or Ordering
Company is ordering Products, Licensed Materials and Services from Supplier
pursuant to this Agreement for use outside the United States.  This template
will be used as the starting point for Supplemental Agreements to address such
purchases and will address the additional country and customer-specific terms
and requirements with the particular transaction.  This Agreement shall govern
Supplier's sale and licensing to Ordering Companies of Supplier's Products,
Licensed Materials and Services for Ordering Companies' internal business uses
only, and does not permit AT&T to resell or sublicense any Products, Licensed
Materials or Services provided hereunder as a distributor of same.  However,
this Agreement, including any restrictions on use, resale and transfer is not
intended to prohibit Ordering Company from reselling or transferring Products
and Licensed Materials no longer needed for the operation of its business,
provided, that, in the case of Software, such transfers are made in accordance
with the provisions of Article 9.  All terms and conditions governing resale or


sublicensing of Supplier's Products, Licensed Materials and Services as a
distributor shall be addressed in a separate agreement.


                                       14




This Agreement is organized in the following manner:  Part 1 sets forth the 
common terms and conditions that apply to all sales and licenses executed 
pursuant to this Agreement, unless otherwise stated in Part 2.  Part 2 sets 
forth the additional terms and conditions which govern Supplier's provision of 
network infrastructure Products, Licensed Materials and Services, other than 
such items currently provided by Supplier's Global Business Communications 
Systems business unit.  Part 3, to be negotiated and executed not later than 
March 31, 1996, shall set forth the additional terms and conditions which 
govern Supplier's provision of Products, Licensed Materials and Services 
provided by Supplier's Global Business Communications System Unit.

                 1A.2     STATEMENT OF ASPIRATIONS.  In an effort to ensure that
the parties remain fully focused upon their shared objectives and aspirations,
the parties agree that the following principles shall govern their work together
during the term of this Agreement:

                 (a)      Both parties want Lucent to provide AT&T with
Products, Licensed Materials and Services that confer significant offer
differentiation, premium value and operating cost reduction consistent with
AT&T's brand equity, and shall work together so that Lucent may assist AT&T in
this manner;

                 (b)      The parties recognize that Lucent's pricing of
Products, Licensed Materials and Services must balance two fundamental
requirements:  AT&T's requirement for the lowest possible operating costs and
Lucent's requirement for adequate return on and recovery of investment;

                 (c)      The parties shall at all times take care to conduct
themselves with the highest integrity, to respect all individuals, and to obtain
the maximum benefits of a shared end user customer focus, effective teamwork and
the parties' innovativeness; and

                 (d)      The parties desire to maintain a relationship that is
warm, open and mutually profitable.

                 1A.3     VOLUME COMMITMENT.  (a) AT&T commits that the
aggregate amount paid by Ordering Companies (including AT&T Wireless Services
Inc.) to Supplier during the calendar years 1996, 1997, and 1998 for Products,
Licensed Materials, and Services, pursuant to this Agreement, any Supplemental
Agreement, any other agreement or otherwise, between an Ordering Company and
Supplier for Supplier's provision of  Products, Licensed Materials or Services
to an Ordering Company, will total at least three billion dollars
($3,000,000,000).  If that commitment is not fulfilled by December 31, 1998,
Supplier shall, in January 1999, bill AT&T a carrying charge equal to the


shortfall at December 31, 1998, multiplied by the Prime Rate (as defined in the
Separation and Distribution Agreement) plus two percent (2%).  Thereafter,
Supplier shall, each month, bill AT&T a carrying charge equal to the shortfall,
if any, at the end of the preceding month, multiplied by 1/12 multiplied by the
Prime Rate plus two percent (2%).  Such billing shall continue until the three
billion dollar ($3,000,000,000) commitment is fulfilled.  AT&T will pay these
bills as set forth in Section  3.2, INVOICES AND TERMS OF PAYMENT.  The remedy
in this Section 1A.3, VOLUME COMMITMENT, is


                                       15




Supplier's exclusive remedy for AT&T's failure to fulfill the three billion
dollar ($3,000,000,000) volume commitment.

                 (b)      AT&T expects, but does not commit, that Products,
Licensed Materials and Services in the amount of one billion three hundred
million dollars ($1,300,000,000), out of the three billion dollar 
($3,000,000,000) total volume commitment, will be ordered in 1996.  Therefore, 
the shortfall billing and payment arrangement set forth in subparagraph 
(a) above does not apply to failure to meet this expectation by the end of 1996.

                 (c)      Prior to the Closing Date (as defined in the
Separation and Distribution Agreement), AT&T shall deliver to Supplier as
advance payment for purchases of Products, Services, Software, or Licensed
Materials an amount equal to five hundred million dollars ($500,000,000).
Commencing on January 1, 1997, Supplier shall apply a portion of such amount as
a credit against any undisputed invoiced amounts due and payable to Supplier
from  AT&T or, if AT&T shall so specify at any time, from any other Ordering
Company, on or after January 1, 1997, in full satisfaction of all obligations of
AT&T or any such Ordering Company then due in connection therewith.  Supplier
shall continue to so apply such advance payment as a credit against such
undisputed invoices until fully applied.

                 1A.4     GOVERNING TERMS.  (a) Current Order Performance:  On
the Effective Date of this Agreement, Supplier shall be in the process of
performing several Ordering Company orders, some of which have not been the
subject of written Orders and purchase agreements.  In addition, Supplier shall
be following many existing engineering, installation and maintenance practices
and procedures that have been developed mutually by Supplier and Ordering
Company but have not been completely documented. The parties intend that
Supplier shall continue to provide the same Products, Services and Licensed
Materials which Supplier is providing or has agreed to provide each Ordering
Company (hereinafter "Pending Orders") subject to the availability of third
party components and provided that Ordering Company shall retroactively
compensate Supplier for any Products, Licensed Materials and Services provided
by Supplier without compensation at the prices and rates set forth in any mutual
agreements entered into.  Exhibit 1A-1 lists the Services, identified thus far,
intended for coverage under this clause and also the Services covered under
other Supplemental Agreements or commercial agreements.  Services to be excluded
include, but are not limited to, real estate and motor vehicles.  The parties
agree to use their best efforts to formalize the Services listed in Exhibit 1A-1
in a commercially reasonable manner (including pricing) that is consistent with
the terms and conditions contained herein no later than March 31, 1996.  Such
retroactive compensation shall begin no earlier than the Effective Date and
shall be capped at twenty million dollars ($20,000,000) per month.  Supplier


shall not be liable for any injury to Ordering Company that results from
Supplier's employees and/or contractors failure to be aware of practices and
procedures that had not, at the time of Supplier's actions, been reduced to
writing.  Supplier and Ordering Company recognize that the existing practices
and procedures will need to be reevaluated in light of the restructure of AT&T.
As part of this reevaluation, Supplier and


                                       16




Ordering Company may decide to continue existing practices and procedures or one
party may notify the other that it wishes to change or eliminate certain
practices or procedures.

The parties agree to use their best efforts to identify any other Products,
Licensed Materials and Services provided by Supplier to Ordering Company that
require commercialization and to formalize such undocumented arrangements in a
commercially reasonable manner that is consistent with the terms and conditions
contained herein no later than March 31, 1996.  The parties acknowledge that
such formalization and modification of those arrangements may result in changes
in the terms and conditions pursuant to which such items are provided.  All
agreements will be reduced to writing which will govern transactions between
Supplier and all Ordering Companies, unless otherwise agreed to.  If the parties
are unable to negotiate a satisfactory resolution, the dispute resolution
provisions of Article 5A herein shall apply.  Services not currently performed
by Supplier are not covered under this Section 1A.4, GOVERNING TERMS, and will
be covered under separate Supplemental Agreements.

With respect to Pending Orders, this Agreement is incorporated by reference,
however, in the event of conflict between the terms and conditions of this
Agreement and the terms and conditions of Pending Orders, the terms and
conditions of Pending Orders shall prevail over the terms and conditions of this
Agreement until such time that the Pending Orders are formalized, terminated or
expired.

                 (b)      Future Procurements:  All future Orders and
Supplemental Agreements pursuant to which Supplier provides Products, Licensed
Materials and Services to AT&T Company shall be deemed to incorporate and be
subject to the terms and conditions of this Agreement, regardless of whether any
such Order or Supplemental Agreement expressly incorporates this Agreement by
reference, unless such Order or Supplemental Agreement expressly provides that
it is not subject to this Agreement.  To the extent that any exhibit to this
Agreement or any document other than a Supplemental Agreement conflicts with the
body of this Agreement, the body of this Agreement shall prevail over such
exhibit or other document.  To the extent that a Supplemental Agreement
conflicts with this General Purchase Agreement, the Supplemental Agreement shall
prevail over the body of this Agreement. To the extent that the Supplemental
General Purchase Agreement, No. LC3757D, conflicts with either or both of this
Agreement and a Supplemental Agreement, the Supplemental General Purchase
Agreement shall prevail over those other agreements.

                 1A.5     TERM OF AGREEMENT.  This Agreement shall become
effective on the Effective Date and shall continue in effect for a period of
five (5) years.  The term of this Agreement shall thereafter be automatically


extended for additional one (1) year periods unless either party provides the
other party one (1) year's prior written notice of its desire to permit this
Agreement to expire without further extension of its term, in which event this
Agreement shall expire on the day before this Agreement would otherwise be
automatically extended.  The amendment or termination of this Agreement shall
not affect the obligations of an Ordering


                                       17




Company or Supplier under any then existing Order or Supplemental Agreement
issued under this Agreement.

                 1A.6     TRANSITION PERIOD.  Although all terms of this
Agreement are effective on the Effective Date, the parties recognize that
complete implementation of certain terms depends upon the development and
deployment of necessary practices and systems.  Those terms include, but are not
limited to:

                 - Section 2.1 -   Orders
                 - Section 2.2 -   Order Acceptance
                 - Section 2.6 -   Order Cancellation and Holds
                 - Section 3.1 -   Pricing
                 - Section 3.2 -   Invoices and Terms of Payment 
                 - Section 5.1 -   Ordering Companies Remedies
                 - Section 5.2 -   Supplier Performance
                 - Section 6.21 -  Record Retention
                 - Section 8.16 -  Planning Information for Orders for
                                   Commercially Available Products
Both parties agree to use their reasonable best efforts to develop and deploy
those practices and systems underlying these and other terms as promptly as
possible, but not later than March 29, 1997. The inability of either party to
comply with any of these terms as a result of not having developed and deployed
such practices and systems prior to March 29, 1997, will not be construed a
breach of contract, provided, however, that if such Supplier's delay in
developing and deploying necessary practices and systems delays affording
Ordering Company the benefits of the Pricing Agreement, Supplier shall afford
those benefits to Ordering Company, as promptly as possible, retroactive to the
Effective Date.

                 1A.7     PURCHASES BY AT&T'S AFFILIATES.  This Agreement shall
govern purchases from Supplier by AT&T, its Affiliates and Ordering Companies,
but shall not govern purchases by other entities.

                 1A.8     ADDITIONAL TECHNOLOGY RIGHTS.  Supplemental Agreements
may provide, on a case-by-case basis, for Ordering Company's ownership (up to
and including 100% ownership) of specified intellectual property rights in
technology newly developed by Supplier solely on behalf of Ordering Company.  In
the event technology is licensed by Supplier to Ordering Company, Supplier may
agree to grant Ordering Company (a) the right to make, have made, use, sell,
modify, offer for sale or import specified Products and provide specified
Services and (b) the title and intellectual property rights to certain
modifications and resulting derivative works made by Ordering Company.

within that period shall be deemed acceptance of Order. Ordering Company or
Supplier may modify the terms or content of any Order if such changes are
mutually agreed to and documented in writing.
  
                 2.3      CHANGES IN ORDERING COMPANY'S ORDERS.  Should Ordering
Company wish to obtain information sufficient to permit it to assess whether to
submit an Order adding, deducting or deviating from a prior Order (hereinafter a
"Change Information Request"), it shall request such information from Supplier
in writing.  As promptly as reasonably possible after its receipt of a Change
Information Request, Supplier shall submit a proposal to Ordering Company which
includes any increases or decreases in Supplier's Price or changes in the
delivery or work schedule for the existing and new Orders necessitated by the
change.  Unless Supplier receives an Order to implement such change from
Ordering Company within  twenty-one (21) calendar days of Ordering Company's
receipt of Supplier's proposal, Ordering Company shall be deemed not to have
authorized the change and Supplier shall remain obligated to perform all
previously ordered work in accordance with (a) the governing Order (for
Products) or (b) for Licensed Material, the governing Order or appropriate
Supplemental Agreement.  Changes by Ordering Company to an accepted Order shall
be treated as a separate Order only if such change materially affects Supplier's
ability to meet its obligations under the original Order, in which case any
Price (or discount, if applicable), shipment date or Services Completion Date
provided by Supplier with respect to such original Order shall be subject to
change.

              

   2.4      CHANGES IN PRODUCTS BY SUPPLIER.  Any change that
Supplier proposes to the Product furnished hereunder and the documentation
related thereto would be subject to the Change Notice Process attached hereto as
Exhibit 2-2.

                 (a)      CANCELLATION FOR CONVENIENCE.

                          (i)     Ordering Company may, upon written notice to

                          (ii)    For those Products and Licensed Materials
         canceled prior to shipment that are considered stock items, Ordering
         Company agrees that it shall pay Supplier an Order cancellation fee
         equal to fifteen percent (15%) of the Price or license fee for such
         items.

                          (iii)   For those Products and Licensed Materials
         considered to be customized or non-stock items (1) not manufactured or

         recoveries and/or salvage value, if any), including, but not limited to
         de-installation, transportation and associated general and
         administrative expenses, plus a reasonable profit in the event that the
         customized or non-stock items are not ultimately sold or licensed to
         another party within ninety (90) days of cancellation, provided that
         Supplier has made a reasonable attempt to sell or license such items.

                          (iv)    If an Order for Services is canceled in whole
         or in part after execution of such Order and prior to the scheduled
         completion of such Services, Ordering Company agrees to pay Supplier
         the fees due for Services provided (which fees, depending upon the
         specific terms of the agreement, may be based on the applicable
         periodic rates or equal to the percentage of the contracted project or
         period that Supplier has completed multiplied by the total fee,
         excluding expenses, for such project or period) and all expenses of any
         type incurred for performing the Services prior to the date of
         cancellation and any expenses Supplier may incur for terminating the
         Services, including but not limited to:

                                  (A)      the cost of materials (less salvage
         value, if any) which have been delivered to the work site prior to the
         date of termination but which have not yet been incorporated into or
         been consumed in performing the Services; plus

                                  (B)      the cost of undelivered materials
        

         ( less salvage value, if any) planned for use in performance of this
         Agreement for which irrevocable Work Orders have been placed by
         Supplier prior to the effective date of cancellation; plus

                                  (C)      the cost of any other capital
         expenditure that has been incurred in order to perform the terminated
         project and that cannot be re-applied by Supplier to provide other
         Services; plus


                                       21




                                  (D)      the cost to Supplier of terminating
         and settling any subcontracts.

                          (v)     For purposes of this subparagraph (a),
         "salvage value" shall include the proceeds of the sale of the
         material to another Ordering Company and the costs Supplier avoids as a
         result of its reapplying materials to meet other needs of Ordering
         Company, the needs of other customers or its own internal needs within
         ninety (90) days of Order cancellation.  Supplier shall make reasonable
         efforts to maximize salvage value. Upon written request, Supplier will
         substantiate such avoided costs.

                 (b)      HOLDS.  Ordering Company may issue "holds" on Orders
or suspend performance under this Agreement, in whole or in part, upon written
notice to Supplier and shall compensate Supplier for any incremental expense
(including, but not limited to, warehousing, loss, damage and inventory carrying
costs) incurred. A hold automatically converts to an Order cancellation after
thirty (30) days.
  
                 (c)      CANCELLATION FOR CAUSE.  In the event Supplier shall
be in material breach or default of any of the terms, conditions, or covenants
of any Order or Supplemental Agreement and if such breach or default shall
continue for a period of forty-five (45) days in 1996 and thereafter thirty
(30) days after Supplier's receipt of notice thereof by Ordering Company, then,
in addition to the remedies specified in Section  5.1, ORDERING COMPANIES'
REMEDIES, Ordering Company shall have the right to cancel such Order or
Supplemental Agreement, except to the extent that Products, Licensed Materials
or Services have previously been provided pursuant to such Order or Supplemental
Agreement.
  
                 (d)      SURVIVAL.  The obligations of this Section 2.5 shall
survive termination of this Agreement.

                 2.6      SHIPPING, PACKING AND DELIVERY.  (a) Supplier shall,
at no additional charge, pack Products in accordance with its standard practices
for shipments to Ordering Company's locations. Unless instructed otherwise by

Order, (iii) mark all subordinate documents with the Order number, (iv) enclose
a packing memorandum with each shipment, and when more than one package is
shipped, identify the package containing the memorandum, and (v) mark Ordering

pay Supplier's additional charges for such packing.  Absent written agreement
otherwise, Supplier will deliver Products and Licensed Materials to Ordering

distribution facility of Supplier or its vendor.


                                       22




  
                 (c)      Unless otherwise directed by Ordering Company,
Supplier shall (i)  ship equipment from its nearest facility or that of its
vendor capable of filling the Order, (ii)  use the lowest available rate from
Ordering Company's pre-selected designated carrier (rail, truck or freight
forwarder), and (iii) prepay transportation charges at cost as a separate item
on Ordering Company's invoice when the cost of transportation is to be borne by
Ordering Company. Ordering Company shall promptly pay to Supplier any prepaid
transportation charges.  Supplier will provide to Ordering Company a
transportation factor card to be used for estimating transportation rates.
Shipping and routing instructions may be furnished or altered by Ordering
Company in writing, subject to additional charges, if applicable.
  
                 (d)      Supplier agrees not to deliver Products prior to five
(5) business days before the agreed upon delivery date without Ordering
Company's prior written authorization.
  
                 2.7      TITLE AND RISK OF LOSS.  Title to and risk of loss to
Products and risk of loss of Licensed Materials shall pass to Ordering Company
upon delivery to Ordering Company.  For purposes of this clause, "delivery"
shall mean the point at which Supplier or Supplier's supplier or agent turns
over possession of the Product or Licensed Materials to Ordering Company,
Ordering Company's employee, Ordering Company's pre-selected designated carrier,
Ordering Company's warehouse, or other Ordering Company's agent and not
necessarily the final destination shown on the Order.  Ordering Company shall
notify Supplier promptly of any claim with respect to loss which occurs while
Supplier has the risk of loss and shall cooperate in every reasonable way to
facilitate the settlement of any claim.

                                  ARTICLE III
                               PRICES AND PAYMENT

                 3.1      PRICES.  (a) To the extent Ordering Company's Order is
subject to a firm price quotation made by Supplier, prices, fees, and charges
("Prices") shall be as set forth in Supplier's firm price quotation or as
specified in the governing Supplemental Agreement.  In all other cases, Prices
shall be as set forth in the Product Information Catalog Extraction System
("PRICES") which provides toll free access to Supplier's complete Product
listing or in ELIB (electronic library information bulletin) or its successor
and will be provided in electronic media. For firm price quotations, Prices
shall be valid for thirty (30) days from the date of the quotation.  Prices
shall be applied based upon the date Supplier receives Ordering Company's Order.
Both parties will work together in the first quarter of 1996 to develop a plan
for the migration to PRICES.
  
 

                (b)      The database for pricing of all Standard Service Units
("SSU's") Products and Services is Service Unit Dictionary System ("SUDS").
  
                 (c)      Where Supplier is not performing installation, all
expenses after shipment from Supplier's manufacturing or software distribution
facility shall be paid by Ordering Company.  If Supplier pays any of such
expenses, they shall be borne by Ordering Company plus


                                       23




a fifteen percent (15%) administration fee. Supplier will not incur such
expenses unless it is requested to do so in writing by Ordering Company (which
request shall constitute Ordering Company's agreement to pay Supplier for such
expenses).

                 (d)      Notwithstanding the foregoing, if Supplier is delayed
from completion of an Order due to any change requested by Ordering Company or
as a result of delay by Ordering Company in furnishing information or in
performing its obligations (including site preparation), Supplier's prices are
subject to change to the extent that Supplier incurs costs for such delay.
  
                 (e)      Unless expressly stated in writing, Supplier's prices
are exclusive of charges for transportation and other related Services, and any
sales or other tax or duty which Supplier may be required to collect or pay upon
the ordered transaction. Supplier shall include these items as separate items in
its invoiced prices to Ordering Company.  Ordering Company shall be responsible
for prepaid transportation paid by Supplier.  Billable premium transportation
will be used only with Ordering Company's concurrence.
  
                 (f)      Supplier may amend its pricing schedules once every
six (6) months by providing sixty (60) days' prior written notice.  Unless the
parties agree otherwise in writing, Supplier's unaccepted firm price quotations
may be amended on ten (10) days' written notice.  Such changes in Supplier's
pricing shall apply only to Orders received on or after the effective date of
such price changes.
  
                 (g)      In addition to the applicable Price, reasonable
expenses for travel and living of Supplier's personnel while on travel
assignments outside the local area, approved by Ordering Company, shall be
reimbursable.  Such approval may be written or oral and on an individual case
basis or for a category of such assignments.  If oral approval is given, it
shall be followed with a written approval in ten (10) days.  Supplier shall
submit invoices for reimbursable travel and living expenses promptly upon
completion of the travel events.  Supplier shall list the travel and living
charges as separate items on each invoice. Supplier shall retain all records in
accordance with IRS standards of such charges for a period of not less than one
(1) calendar year after the expiration of the travel assignment.  Upon
reasonable request in the event of a question, Supplier shall make such records
available for inspection by Ordering Company.
  
                 3.2      INVOICES AND TERMS OF PAYMENT.

                 (a)      FOR CALENDAR YEAR 1996.  Invoices and terms of payment
shall be mutually agreed to by both parties no later than March 1, 1996.  The


intent is that both parties will plan a movement toward the terms of Section
3.2(b), INVOICES AND TERMS OF PAYMENT, and away from the current practice,
NS/NSD Payment and Invoicing Policy dated January 30, 1995. The principles for
1996 which the parties will strive to meet will include (i) the provision of a
single bill per order on last shipment; (ii) such bill shall not be submitted
manually; (iii) billing upon shipment for Products, Licensed Materials
(including transportation charges and taxes, if applicable) and Engineering,
except engineering Services associated with


                                       24




outside plant construction; (iv) billing for Installation upon Installation
Complete Date; and (v) implementation on or before April 1, 1996.

                 (b)      AFTER 1996.

                          (i)      Products, Licensed Materials (including
transportation charges and taxes, if applicable), and Engineering Services,
except engineering Services associated with outside plant construction, shall
be billed by Supplier when last shipment on an Order is made, or as soon
thereafter as practical;

                          (ii)     Installation shall be billed upon Acceptance;

                          (iii)    Engineering Services associated with outside
plant construction shall be billed as performed or, at Supplier's discretion,
on a monthly basis;

                          (iv)     Consulting, design, outside plant
construction, system integration and program management Services shall be
billed, as mutually agreed to by the parties (1) on a progress basis based on
the percentage of job completed up to eighty-five percent of the charge or, (2)
on a monthly basis.  Final billing for such Services will be invoiced when such
Service is completed;

                          (v)     Unless otherwise agreed to, Maintenance
Services shall be billed monthly, in advance.  Supplier will work with Ordering
Company to minimize the number of bills Ordering Company receives each month
for such Services.  If Ordering Company requests quarterly or annual invoicing,
such invoicing shall be rendered in advance of such Services;

                          (vi)    Payment for generally available Licensed
Material is payable in full upon delivery to First Field Application; and

                          (vii)   Software and/or other technology development
for small projects (i.e. less than or equal to fifteen million dollars 
($15,000,000) and less than or equal to twelve (12) months) shall be billed as 
follows:  ten percent (10%) at commitment (i.e., signing of contract), forty 
percent (40%) upon delivery of the Software to the Integrated Test Network (if 
the Software will not be tested in the ITN, this forty percent (40%) payment 
shall be due upon delivery to the First Field Application), and fifty percent 
(50%) when Software is ready for deployment, or thirty (30) days after 
Acceptance of the Software in the First Field Application, whichever occurs 
sooner. Billing for Software and/or other technology development for projects 
other than small projects as defined in the preceding sentence, shall be 


determined on a case by case basis.  The parties will conform the Supplemental 
Agreements to this Section 3.4(b)(vii) by March 31, 1996.

                 (c)      Ordering Company shall pay such invoiced amounts, less
any items known then to be disputed items, within thirty (30) days of the date
of Supplier's invoice. Ordering Company shall notify Supplier of any disputed
invoice within eighteen (18) months from the date of the invoice.  Such notice
of dispute shall not excuse Ordering Company from timely payment of the
undisputed portion(s) of any invoice containing a disputed portion.


                                       25




Supplier may apply any credit which remains outstanding in favor of Ordering
Company to the oldest undisputed invoice which remains in Ordering Company's
account, unless directed otherwise by Ordering Company.

                 (d)      Unless otherwise agreed, payment of all amounts
contained in this Agreement shall be made in United States dollars and invoices
shall be rendered in the same currency.  Unless otherwise agreed to by Supplier
and Ordering Company, payments shall be made by electronic transfer to the
account and address indicated by Supplier and shall reference the invoice(s) to
which they relate.

                 (e)      AT&T guarantees payment in United States dollars of
the obligations of Ordering Companies that are not Affiliates of AT&T on any
Orders placed pursuant to this Agreement.  Payment shall be made by AT&T  within
thirty (30) days after receipt of invoice of a guaranteed payment.  Such invoice
will only be issued to AT&T after Supplier has made reasonable efforts to obtain
payment from Ordering Company. Ordering Companies that are Affiliates of AT&T
shall bear sole responsibility for the performance of their obligations
hereunder.

                 3.3      TAXES.  (a) Ordering Company shall bear all taxes,
levies, duties and other similar charges (and any related interest and
penalties), however designated, (herein referred to as "Tax") imposed as a
result of the existence or operation of this Agreement, Order or any
Supplemental Agreement, including but not limited to any tax which Ordering
Company is required to withhold, collect or deduct from payments to Supplier,
except (i) any tax imposed upon Supplier in a jurisdiction outside the United
States if such tax is allowable as a credit against the United States income
taxes of Supplier; and (ii) any net income tax imposed upon Supplier by the
United States or any governmental entity within the United States proper (the
fifty (50) states and the District of Columbia including, but not limited to
counties, municipalities and other localities).  In order for the exception
contained in (i) to apply, Ordering Company must furnish Supplier with such
evidence as may be required by United States taxing authorities to establish
that such Tax has been paid, if any, so Supplier may claim the credit.

                 (b)      If Ordering Company is required to bear a tax pursuant
to paragraph (a) above, Ordering Company shall pay to Supplier or the
appropriate government entity or taxing authority, such Tax and other charges
and any additional amounts as are necessary to ensure that the net amounts
received by Supplier after all such payments or withholdings equal the amounts
to which Supplier is otherwise entitled under this Agreement as if such Tax or
other charges did not exist.

 

                (c)      If Ordering Company is exempt from any Tax, Ordering
Company shall provide Supplier with all required documentation necessary to
establish Ordering Company's exempt status.  Ordering Company hereby agrees to
indemnify Supplier from any Tax, including penalties and interest, resulting
from Supplier's reliance on Ordering Company's claim of exempt status.


                                       26




                 (d)      If Ordering Company disputes in good faith the
applicability of any Tax imposed as a result of the existence or operation of
this Agreement, Ordering Company, at its own expense and in its own name, may
contest the taxing jurisdiction of the disputed Tax.  In the event the
applicable law requires that such contest must be taken in the name of  Supplier
only, Supplier shall in good faith and with due diligence at Ordering Company's
sole expense contest the imposition of such Tax provided that (i) Supplier will
not be required to pursue such contest if the action will result in a lien
against Supplier for which Ordering Company has not adequately indemnified
Supplier or (ii) will result in a penalty being assessed against Supplier for
which Ordering Company has not adequately indemnified Supplier.


                                   ARTICLE IV
                          INTELLECTUAL PROPERTY RIGHTS

                 4.1      USE OF INFORMATION.  (a) All technical and business
Information disclosed by one party to the other subsequent to the execution of
this Agreement in whatever form recorded which is marked "proprietary" or
"confidential" or bears a legend or notice restricting its use, copying, or
dissemination or, if not in tangible form, is described as being proprietary or
confidential at the time of disclosure and is subsequently summarized in a
writing so marked and delivered to the receiving party within thirty (30) days
of disclosure to the receiving party shall remain the property of the furnishing
party.  Similarly, all technical and business Information disclosed by one party
to the other party prior to the execution of this Agreement and described at the
time of disclosure by the furnishing party as being proprietary or confidential
or known by the party receiving disclosure of such Information to be proprietary
or confidential shall remain the property of the furnishing party (regardless of
whether it is ever recorded in tangible form).

                 (b)      The furnishing party grants the receiving party the
right to use such Information only as follows:  Such Information (i) shall not
be reproduced or copied, in whole or part, except for use as authorized in this
Agreement; and (ii) shall, together with any full or partial copies thereof, be
returned or destroyed when no longer needed. Supplier shall use Ordering
Company's Information only for the purpose of performing under this Agreement,
and Ordering Company shall use Supplier's Information only (i) to order
Products, Licensed Materials or Services; (ii) to evaluate Supplier's Products,
Licensed Materials or Services; or (iii) to install, operate and maintain the
particular Products or Licensed Materials for which such Information was
originally furnished.  Unless the furnishing party consents in writing, such
Information, except for that part, if any, which was previously 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, or
which a receiving party receives from a third party without restriction, or
which is independently developed by the receiving party, shall be held in
confidence by 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 that


                                       27




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.  The contents of this Agreement are
confidential and shall not be disclosed by either party to third parties,
without the prior written agreement of both parties hereto, except to the extent
required by applicable law, a court or regulatory agency of competent
jurisdiction.
  
                 (c)  Each party shall be liable to the other for damages
resulting from violation of this Section 4.1.  Those damages shall be unlimited
as to nature and limited as to amount to thirty million dollars ($30,000,000)
per occurrence.

                 4.2      INFRINGEMENT AND MISAPPROPRIATION.  (a) In the event
of any claim, action, proceeding or suit by a third party against Ordering
Company alleging an infringement of any patent, copyright, trademark or
misappropriation of a trade secret recognized in any jurisdiction where an
Ordering Company may lawfully use or operate Products or Licensed Materials
purchased hereunder, or if by reason of the use, in accordance with Supplier's
Specifications, in any such jurisdiction of any Products or Licensed Materials
furnished by Supplier to an Ordering Company under this Agreement, Supplier, at
its expense, shall defend Ordering Company, subject to the conditions and
exceptions stated in Paragraphs (b), (c), (d), and (e) below.  Supplier shall
reimburse Ordering Company for all costs, expenses or attorneys' fees incurred
at Supplier's written request or authorization, and shall indemnify Ordering
Company against any liability assessed against Ordering Company by final
judgment on account of such infringement or violation arising out of such use.
In no event shall Supplier be liable for Ordering Company's consequential
damages.
  
                 (b)      If Ordering Company's use is enjoined or in Supplier's
opinion is likely to be enjoined, Supplier shall, at its expense use its
reasonable best efforts, to either (i) replace the enjoined Product or Licensed
Materials furnished pursuant to this Agreement with a substitute free of any
infringement; (ii) modify it so that it will be free of the infringement; or
(iii) procure for Ordering Company a license or other right to use it.  If none
of the foregoing options is achievable through reasonable best efforts, Supplier
shall remove the enjoined Product or Licensed Materials and refund or credit to
Ordering Company any amounts paid to Supplier therefor less a reasonable charge
for depreciation and any actual period of use by Ordering Company.  In no event,
however, shall Supplier's liability under this Section 4.2(b) exceed the
amount(s) paid by Ordering Company to Supplier to purchase the Product or to
obtain the right to use the Licensed Materials which are alleged to violate the


rights described in Paragraph (a) above.

                 (c)      Ordering Company shall give Supplier prompt written
notice of all such claims, actions, proceedings or suits alleging infringement
or violation and Supplier shall have full and complete authority to assume the
sole defense thereof, including appeals, and to settle same. Ordering Company
shall, upon Supplier's request and at Supplier's expense, furnish all


                                       28




information and assistance available to Ordering Company and cooperate in every
reasonable way to facilitate the defense and/or settlement of any such claim,
action, proceeding or suit.
  
                 (d)      No undertaking of Supplier under this clause shall
extend to any such alleged infringement or violation to the extent that it:  (i)
solely arises from adherence to design modifications, Specifications, drawings,
or written instructions which Supplier is directed by Ordering Company to follow
but only if such alleged infringement or misappropriation does not reside in
material of Supplier's origin, design or selection; or (ii) arises from
adherence to instructions to apply Ordering Company's trademark, trade name or
other company identification; or (iii) resides in equipment or Software which is
furnished by Ordering Company to Supplier for use under this Agreement; or (iv)
arises from use of the Product or Licensed Materials provided by Supplier in
combination with any item not furnished directly by Supplier; or (v) is based
upon modification made by Ordering Company of any Product or Licensed Materials;
or (vi) arises from use of any Product or Licensed Material in a manner for
which it was not designed.  In the foregoing cases numbered (i) through (vi),
Ordering Company shall defend and save Supplier harmless, subject to the same
terms and conditions and exceptions stated above, with respect to Supplier's
rights and obligations under this clause.
  
                 (e)      The liability of Supplier, AT&T and Ordering Company
with respect to any and all claims, actions, proceedings or suits by third
parties alleging infringement of patents, trademarks or copyrights or violation
of trade secrets or proprietary rights because of, or in connection with, any
Products or Licensed Materials furnished pursuant to this Agreement shall be
limited to the specific undertakings contained in this Section 4.2.
  
                 4.3      NO PATENT LICENSES.  Nothing contained herein shall be
construed as conferring by implication, estoppel or otherwise any license or
right under any patent, except that which is essential to the use of the
Products and/or Licensed Materials as provided by Supplier, and provided however
that this Section 4.3 shall not limit or modify any of the rights and
obligations of the Intellectual Property Agreements or the Supplemental General
Purchase Agreement, No. LC3757D, both executed as of this date as Ancillary
Agreements to the Separation and Distribution Agreement.  Supplier shall retain
all ownership rights in all intellectual property used or embodied in Supplier's
Products, Licensed Materials and Service unless otherwise expressed herein, or
in a Supplemental Agreement.
  
                 4.4      TRADEMARKS.  (a) Subject to the provisions of the
Brand License Agreement, executed as of this date as an Ancillary Agreement to
the Separation and Distribution Agreement, each party shall have the right to


use Products and Licensed Materials which bear the other party's  trademarks,
trade name, logos, trade devices, service marks, symbols, and codes, unless
otherwise directed by that party to remove such indicia.
  
                 (b)      Except as provided in Section s 4.4 (a) above, each
party (including in the case of AT&T, each Ordering Company)  shall not use in
advertising or otherwise, any of the other party's  trade name, logo, trademark,
trade device, service mark, symbol, code or Specification, or any abbreviation,
contraction, or simulation thereof, without the prior written


                                       29




consent of such party.  Neither party  shall claim any ownership therein, and
any such usage shall inure to the benefit of the party which owns such trade
name, logo, trademark, trade device, service mark, symbol, code or
Specification.
  
                 4.5      PROPRIETARY NOTICE. Ordering Company shall reproduce
and include any Supplier copyright or proprietary notice on all authorized
copies of Licensed Materials.  Ordering Company shall also mark all media
containing such copies with a warning that the Licensed Materials are subject to
restrictions contained in an agreement between Supplier and AT&T and that such
Licensed Material are the property of Supplier.

         (a) An Ordering Company's exclusive remedies and the entire liability
of Supplier, Supplier's Affiliates and their employees and agents, and their
vendors for any claim, loss, damage or expense of Ordering Company or any other

warranty -- the remedy shall include those set forth in the applicable 
"warranty" clause;

                          (iv)    For third party claims against Ordering
Company for personal injury and property damage for which Supplier is held

                          (v)     For tangible property damage to Ordering
Company caused by Supplier's negligence -- the amount of the direct damages; and
 
                          (vi)    For Supplier's failure to deliver Products,


Licensed Materials or Services on Supplier's scheduled delivery date, if
Supplier fails to deliver such Products, Licensed Materials or Services (aa) in
1996 within forty-five (45) days from receipt of written notice from Ordering
Company to Supplier of its failure to deliver such Products, Licensed


                                       30




Materials or Services on Supplier's scheduled delivery date and (ab) thereafter
thirty (30) days from receipt of such notice, the following remedies shall

                                  (A)      Ordering Company may cancel the Order
without incursion of cancellation fees; and,

                                  (B) Ordering Company may request and Supplier
will reduce AT&T's volume purchase commitment by an amount equal to the value of
the Order.  In addition, if a worldwide supply shortage exists, Ordering Company
may request and, upon such request, shall receive priority on allocation of such
delivered Products, Licensed Materials or Services in a shortage condition based
upon priority criteria agreed to between Supplier and its affected customers
established for the particular shortage condition.
  
                 (b)      Notwithstanding any other provision of this Agreement
and except as provided in Section 5.1(a)(ii) above, ORDERING COMPANIES'
REMEDIES, Supplier, Supplier's Affiliates and their employees and agents, and
their vendors shall not be liable for any consequential damages in the nature of
lost profits, revenues or savings arising out of this Agreement, or the use or
performance of any Product, Licensed Materials, or Services, whether in an
action for or arising out of breach of contract, warranty, tort, including
negligence, or strict liability.

above, ORDERING COMPANIES' REMEDIES, Supplier's total liability for incidental
and/or consequential damages and damages resulting from network outages which
must be reported by Ordering Company to the Federal Communications Commission in
accordance with its rules ("Network Outage(s)") shall not exceed ten million
dollars ($10,000,000) per occurrence with a total not to exceed of thirty
million dollars ($30,000,000) in any one year.  This Section 5.1(c) shall
survive failure of an exclusive or limited remedy.
  
                 (d)      Ordering Company shall give Supplier prompt written

                 (e)      Supplier acknowledges that a Network Outage will cause
damage to AT&T in an amount impossible to ascertain. Supplier agrees to pay
AT&T, as liquidated damages and not as a penalty, the sum of one million dollars
($1,000,000) per occurrence in the event of a Network Outage caused solely by
Supplier in connection with network infrastructure equipment and one hundred
thousand dollars ($100,000) per occurrence in the event of a Network Outage
caused solely by Supplier in connection with GBCS Products, whether or not by


breach of warranty and whether before, during or after any Warranty Period.
With respect to a Network Outage caused solely by Supplier in connection with
network infrastructure equipment, Supplier's total liability for damages for
Network Outages, including the liquidated damages described herein shall be one
million dollars ($1,000,000) per occurrence not to exceed the amount of three
million dollars ($3,000,000) for any calendar year, and Supplier's total
liability


                                       31

including the liquidated damages described herein, shall be five million dollars
($5,000,000); provided that AT&T is meeting its obligations specified in Section
1A.3, VOLUME COMMITMENT, and the Pricing Agreement.  With respect to Network
Outages caused solely by Supplier in connection with GBCS Products, Supplier's
total liability under this section shall be one hundred thousand dollars
($100,000) per occurrence not to exceed the amount of three hundred thousand
dollars ($300,000) for any calendar year ,and Supplier's total liability for
damages for Network Outages for any three (3) year period of this Agreement,
including the liquidated damages described herein, shall be five hundred
thousand dollars ($500,000); provided that AT&T is meeting its obligations
specified in Section 1A.3, VOLUME COMMITMENT, and the Pricing Agreement. If, at
any time during the term of this Agreement, AT&T fails to meet its obligations
specified in Section 1A.3, VOLUME COMMITMENT, and the Pricing Agreement, it
shall not be entitled to the remedy in this Section 5.1(e).  Any damages paid by
Supplier pursuant to this Subparagraph shall be considered incidental and
consequential damages subject to the limitations on AT&T's right to recover same
that are set forth in Section 5.1(c), ORDERING COMPANIES' REMEDIES. At AT&T's
option, AT&T may take all or part of the payment as a credit against any invoice
due or to become due to Supplier.   The remedies available to AT&T under Section
5.1, ORDERING COMPANIES'  REMEDIES, and the foregoing liquidated damages shall
constitute AT&T's sole and exclusive remedy for Network Outages caused to any
extent by Supplier during the term of this Agreement.
  
                 5.2      SUPPLIER PERFORMANCE.   AT&T and Supplier will jointly
develop requirements for an annual Supplier Merit Award by December 1st of each
year for the following year.  For 1996, the requirements are listed in Exhibit
5-1.  The award program will provide that if Supplier meets or exceeds either
award performance criteria for receipt of a Supplier Merit Award, AT&T shall:

                          (a)     increase its minimum volume purchase
commitment for the following year (if the volume purchase commitment in Section
1A.3, VOLUME COMMITMENT, is in effect), by twenty million dollars ($20,000,000)
for achieving the on-time delivery criteria and ten million dollars
($10,000,000) for achieving the FCC reportable incidents criteria or
  
                          (b)     if a volume purchase commitment is not in
effect, increase its purchase or license of Supplier's Products, Licensed
Materials and Services for the following year by twenty million dollars
($20,000,000) for achieving the on-time delivery criteria and ten million
dollars ($10,000,000) for achieving the FCC reportable incidents criteria. A
public relations program will be jointly developed and executed in support of
this award program.
  
 

                5.3      INSURANCE.  Supplier shall maintain and cause
Supplier's subcontractors to maintain during the term of this Agreement:  (a)
Workers' Compensation insurance as prescribed by the law of the state or nation
in which the work is performed, (b) employer's liability insurance with limits
of at least three hundred thousand dollars ($300,000) for each occurrence; (c)
comprehensive automobile liability insurance if the use of motor vehicles is
required, with


                                       32




limits of at least one million dollars ($1,000,000) combined single limit for
bodily injury and property damage for each occurrence; (d) Comprehensive General
Liability ("CGL") insurance, including Blanket Contractual Liability and Broad
Form Property damage, with limits of at least one million dollars ($1,000,000)
combined single limit for personal injury and property damage for each
occurrence; and (e) if the furnishing to Ordering Company (by sale or otherwise)
of Products or material is involved, CGL insurance endorsed to include products
liability and completed operations coverage in the amount of five million
dollars ($5,000,000) for each occurrence.  If specifically requested by Ordering
Company, Supplier's subcontractors shall furnish, prior to the start of work,
certificates or adequate proof of the foregoing insurance, including copies of
the endorsements and insurance policies.  Supplier's obligations to maintain
insurance may be satisfied by providing proof of self-insurance in a form
satisfactory to Company.

                        ARBITRATION;  DISPUTE RESOLUTION

                 5A.1     AGREEMENT TO ARBITRATE.  The procedures for
discussion, negotiation and arbitration set forth in this Article 5A shall apply
to all disputes, controversies or claims (whether sounding in contract, tort or
otherwise) that may arise out of or related to, or arise under or in connection
with this Agreement or any Supplemental Agreement, or the transactions
contemplated hereby or thereby (including all actions taken in furtherance of
the transactions contemplated hereby or thereby on or prior to the date hereof),
or the commercial or economic relationship of the parties relating hereto,
between the parties.  Each party agrees that the procedures set forth in this
Article 5A shall be the sole and exclusive remedy in connection with any
dispute, controversy or claim relating to any of the foregoing matters and
irrevocably waives any right to commence any Action in or before any
Governmental Authority except as expressly provided in Section 5A.7(b), CERTAIN
ADDITIONAL MATTERS, and 5A.8, LIMITED COURT ACTIONS, below and except to the
extent provided under the Arbitration Act in the case of judicial review of
arbitration results or awards.  Each party on behalf of itself irrevocably
waives any right to any trial by jury with respect to any such claim,
controversy, or dispute.  

                 5A.2     ESCALATION.  (a)  It is the intent of the parties to
use their respective reasonable best efforts to resolve expeditiously any
dispute, controversy or claim between or among them with respect to the matters
covered hereby that may arise from time to time on a mutually acceptable
negotiated basis.  In furtherance of the foregoing, any party involved in a
dispute, controversy or claim may deliver a notice (an "Escalation Notice")


demanding an in-person meeting involving representatives of the parties at a
senior level of management of the parties (or if the parties agree, of the
appropriate strategic business unit or division within such entity).  A copy of
any such Escalation Notice shall be given to the General Counsel, or like
officer or official, of each party involved in the dispute, controversy or claim
(which copy shall state that it is an Escalation Notice pursuant to this
Agreement).  Any agenda, location or procedures for such discussions or
negotiations between the parties may be established by the


                                       33




parties from time to time; provided, however, that the parties shall use their
reasonable best efforts to meet within thirty (30) days of the Escalation
Notice.

                 (b)  The parties may, by mutual consent, retain a mediator to
aid the parties in their discussions and negotiations by informally providing
advice to the parties.  Any opinion expressed by the mediator shall be strictly
advisory and shall not be binding on the parties, nor shall any opinion
expressed by the mediator be admissible in any arbitration proceedings.  The
mediator may be chosen from a list of mediators previously selected by the
parties or by other agreement of the parties.  Costs of the mediation shall be
borne equally by the parties involved in the matter, except that each party
shall be responsible for its own expenses.  Mediation is not a prerequisite to a
demand for arbitration under Section 5A.3, DEMAND FOR ARBITRATION.

                 5A.3     DEMAND FOR ARBITRATION.  (a) At any time after the
first to occur of (i) the date of the meeting actually held pursuant to the
applicable Escalation Notice or (ii) forty five (45) days after the delivery of
an Escalation Notice (as applicable, the "Arbitration Demand Date"), any party
involved in the dispute, controversy or claim (regardless of whether such party
delivered the Escalation Notice) may, unless the applicable deadline has
occurred, make a written demand (the "Arbitration Demand Notice") that the
dispute be resolved by binding arbitration, which Arbitration Demand Notice
shall be given in the manner set forth in Section 6.3, NOTICES.  In the event
that any party shall deliver an Arbitration Demand Notice to another party, such
other party may itself deliver an Arbitration Demand Notice to such first party
with respect to any related dispute, controversy or claim with respect to which
the applicable deadline has not passed without the requirement of delivering an
Escalation Notice.  No party may assert that the failure to resolve any matter
during any discussions or negotiation, the course of conduct during the
discussions or negotiations or the failure to agree on a mutually acceptable
time, agenda, location or procedures for the meeting, in each case, as
contemplated by Section 5A.2, ESCALATION, is prerequisite to a demand for
arbitration under this Section 5A.3.

                 (b)  Any Arbitration Demand Notice may be given until one year
and forty-five (45) days after the later of the occurrence of the act or event
in the exercise of reasonable due diligence giving rise to the underlying claim
or the date on which such act or event was, or should have been, discovered by
the party asserting the claim (as applicable, and as it may in a particular case
be specifically extended by the parties in writing, the "Applicable Deadline").
Any discussions, negotiations or mediations between the parties pursuant to this
Agreement or otherwise will not toll the Applicable Deadline unless expressly
agreed in writing by the parties.  Each of the parties agrees that if an


Arbitration Demand Notice with respect to a dispute, controversy or claim is not
given prior to the expiration of the Applicable Deadline, as between or among
the parties, such dispute, controversy or claim will be barred.  Subject to
Section 5A.7(d), CERTAIN ADDITIONAL MATTERS, and 5A.8, LIMITED COURT
ACTIONS,
upon delivery of an Arbitration Demand Notice pursuant to Section 5A.3(b),
DEMAND FOR ARBITRATION, prior to the Applicable Deadline, the dispute,
controversy or claim shall be decided by a sole arbitrator in accordance with
the rules set forth in this Article 5A.


                                       34




                 5A.4   ARBITRATORS.  (a)  Within fifteen (15) days after a
valid Arbitration Demand Notice is given, the parties involved in the dispute,
controversy or claim referenced therein shall attempt to select a sole
arbitrator satisfactory to all such parties.

                 (b)  In the event that such parties are not able to jointly
select a sole arbitrator within such fifteen (15) day period, such parties shall
each appoint an arbitrator within thirty (30) days after delivery of the
Arbitration Demand Notice.  If one party appoints an arbitrator within such time
period and the other party or parties fail to appoint an arbitrator within such
time period, the arbitrator appointed by the one party shall be the sole
arbitrator of the matter.

                 (c)  In the event that a sole arbitrator is not selected
pursuant to paragraph (a) or (b) above and, instead, two (2) or three (3)
arbitrators are selected pursuant to paragraph (b) above, the two or three
arbitrators will, within thirty (30) days after the appointment of the later of
them to be appointed, select an additional arbitrator who shall act as the sole
arbitrator of the dispute.  After selection of such sole arbitrator, the initial
arbitrators shall have no further role with respect to the dispute.  In the
event that the arbitrators so appointed do not, within thirty (30) days after
the appointment of the later of them to be appointed, agree on the selection of
the sole arbitrator, any party involved in such dispute may apply to CPR, New
York, New York, to select the sole arbitrator, which selection shall be made by
such  organization within thirty (30) days after such application.  Any
arbitrator selected pursuant to this paragraph (c) shall be disinterested with
respect to any of the parties and the matter and shall be reasonably competent
in the applicable subject matter.

                 (d)  The sole arbitrator selected pursuant to paragraph (a),
(b) or (c) above will set a time for the hearing of the matter which will
commence no later than ninety (90) days after the date of appointment of the
sole arbitrator pursuant to paragraph (a), (b) or (c) above, and which hearing
will be no longer than thirty (30) days (unless in the judgment of the
arbitrator the matter is unusually complex and sophisticated and thereby
requires a longer time, in which event such hearing shall be no longer than
ninety (90) days).  The final decision of such arbitrator will be rendered in
writing to the parties not later than sixty (60) days after the last hearing
date, unless otherwise agreed by the parties in writing.

                 (e)  The place of any arbitration hereunder will be New Jersey,
unless otherwise agreed by the parties.

                 5A.5     HEARINGS.  Within the time period specified in Section


5A.4(d), ARBITRATORS, the matter shall be presented to the arbitrator at a
hearing by means of written submissions of memoranda and verified witness
statements, filed simultaneously, and responses, if necessary in the judgment of
the arbitrator or both parties.  If the arbitrator deems it to be essential to a
fair resolution of the dispute, live cross-examination or direct examination may
be permitted, but is not generally contemplated to be necessary.  The arbitrator
shall actively manage the arbitration with a view to achieving a just, speedy
and cost-effective resolution of the dispute, claim or controversy.  The
arbitrator may, in his discretion, set time and other limits on the presentation
of each party's case, its memoranda or other submissions, and refuse to receive


                                       35




any proffered evidence, which the arbitrator, in his discretion, finds to be
cumulative, unnecessary, irrelevant or of low probative nature.  Except as
otherwise set forth herein, any arbitration hereunder will be conducted in
accordance with the CPR Rules for Non-Administered Arbitration of Business
Disputes (except that the arbitration will not be conducted under the auspices
of the CPR and the fee schedule of the CPR will not apply).  Except as expressly
set forth in Section 5A.8(b), LIMITED COURT ACTIONS, the decision of the
arbitrator will be final and binding on the parties, and judgment therein may be
had and will be enforceable in any court having jurisdiction over the parties.
Arbitration awards will bear interest at an annual rate of the Prime Rate Plus
two percent (2%) per annum.  To the extent that the provisions of this Agreement
and the prevailing rules of the CPR conflict, the provisions of this Agreement
shall govern.

                 5A.6     DISCOVERY AND CERTAIN OTHER MATTERS.  (a)  Any party
involved in the applicable dispute may request limited document production from
the other party or parties of specific and expressly relevant documents, with
the reasonable expenses of the producing party incurred in such production paid
by the requesting party.  Any such discovery (which rights to documents shall be
substantially less than document discovery rights prevailing under the Federal
Rules of Civil Procedure) shall be conducted expeditiously and shall not cause
the hearing provided for in Section 5A.5, HEARINGS, to be adjourned except upon
consent of all parties involved in the applicable dispute or upon an
extraordinary showing of cause demonstrating that such adjournment is necessary
to permit discovery essential to a party to the proceeding.  Depositions,
interrogatories or other forms of discovery (other than the document production
set forth above) shall not occur except with the consent of the parties involved
in the applicable dispute.  Disputes concerning the scope of document production
and enforcement of the document production requests will be determined by
written agreement of the parties involved in the applicable dispute or, failing
such agreement, will be referred to the arbitrator for resolution.  All
discovery requests will be subject to the proprietary rights and rights of
privilege of the parties, and the arbitrator will adopt procedures to protect
such rights and to maintain the confidential treatment of the arbitration
proceedings (except as may be required by law).  Subject to the foregoing, the
arbitrator shall have the power to issue subpoenas to compel the production of
documents relevant to the dispute, controversy or claim.
  
                 (b)  Except where contrary to the provisions set forth in this
Agreement or any Supplemental Agreement, the rules of the CPR for commercial
arbitration will be applied to all matters of procedure, including discovery.
The arbitrator shall have full power and authority to determine issues of
arbitrability but shall otherwise be limited to interpreting or continuing the
applicable provisions of this Agreement and will have no authority or power to


limit, expand, alter, amend, modify, revoke or suspend any condition or
provision of the Agreement; it being understood, however, the arbitrator will
have full authority to implement the provisions of this Agreement, and to
fashion appropriate remedies for breaches of this Agreement (including, other
than in the case of disputes, controversies or claims relating to, arising out
of or resulting from Patents (as such term is defined in the Patent License
Agreement), interim or permanent injunctive relief); provided that the
arbitrator shall not have (i) any authority in excess of the


                                       36




authority a court having jurisdiction over the parties and the controversy or
dispute would have absent these arbitration provisions or (ii) any right or
power to award punitive damages.  It is the intention of the parties that in
rendering a decision, the arbitrator give effect to the applicable provisions of
this agreement and follow applicable law (it being understood and agreed that
this sentence shall not give rise to a right of judicial review of the
arbitrator's award).
  
                 (c)  If a party fails or refuses to appear at and participate
in an arbitration hearing after due notice, the arbitrator may hear and
determine the controversy upon evidence produced by the appearing party.

                 (d)  Arbitration costs will be borne equally by each party
involved in the matter, except that each party will be responsible for its own
attorneys fees and other costs, expenses, including the costs of witnesses
selected by such party.

                 5A.7    CERTAIN ADDITIONAL MATTERS.  (a) Any arbitration award
shall be a bare award limited to a holding for or against a party and shall be
without findings as to facts, issues or conclusions of law (including with
respect to any matters relating to the validity or infringement of Patents) and
shall be without a statement of the reasoning on which the award rests, but must
be in adequate form so that a judgment of a court may be entered thereupon.
Judgment upon any arbitration award hereunder may be entered in any court having
jurisdiction thereof.
  
                 (b)  Prior to the time at which an arbitrator is appointed
pursuant to Section 5A.4(c), ARBITRATORS, any party may seek one or more
temporary restraining orders in a court of competent jurisdiction if necessary
in order to preserve and protect the status quo.  Neither the request for, nor
grant or denial of, any such temporary restraining order shall be deemed a
waiver of the obligation to arbitrate as set forth herein and the arbitrator may
dissolve, continue or modify any such order.  Any such temporary restraining
order shall remain in effect until the first to occur of the expiration of the
order in accordance with its terms or the dissolution thereof by the arbitrator.

                 (c)  Except as required by law, the parties shall hold, and
shall cause their respective officers, directors, employees, agents and other
representatives to hold, the existence, content and result of mediation or
arbitration in confidence in accordance with the provisions of Section 6.2 and
except as may be required in order to enforce any award.  Each of the parties
shall request that any mediator or arbitrator comply with such confidentiality
requirement.

 

                (d)  In the event that at any time the sole arbitrator shall
fail to serve as an arbitrator for any reason, the parties shall select a new
arbitrator who shall be disinterested as to the parties and the matter in
accordance with the procedures set forth herein for the selection of the initial
arbitrator.  The extent, if any, to which testimony previously given shall be

reasonably likely to be, in excess of one hundred million dollars ($100,000,000)
and if such party desires to commence an Action in lieu of complying with the
arbitration provisions of this Article, such party shall so state in its
Arbitration Demand Notice.  If the other parties to the arbitration do not agree
that the amount in controversy in such dispute, controversy or claim (or such
series of related disputes, controversies or claims) is, or is reasonably likely
to be, in excess of one hundred million dollars ($100,000,000), the arbitrator
selected pursuant to Section 5A.4, ARBITRATORS, hereof shall decide whether the

controversy in such dispute, controversy or claim (or such series of related
disputes, controversies or claims) is, or is reasonably likely to be, in excess
of one hundred million dollars ($100,000,000), the provisions of Sections
5A.4(d), and (e), ARBITRATORS, 5A.5, HEARINGS, 5A.6, DISCOVERY AND CERTAIN

                 5A.9    CONTINUITY OF SERVICE AND PERFORMANCE.  Unless
otherwise agreed in writing, the parties will continue to provide service and
honor all other commitments under this Agreement during the course of dispute

                 5A.10  LAW GOVERNING ARBITRATION PROCEDURES.  The
interpretation of the provisions of this Article 5A, only insofar as they relate

                                   ARTICLE VI
                                 MISCELLANEOUS

                 6.1      EXPORT CONTROL.  The parties acknowledge that
Products, Licensed Materials and Information (including, but not limited to,
Services and training) provided under this Agreement are subject to U.S. export
laws and regulations, and any use or transfer of such Products and Information
must be authorized under those regulations.  AT&T agrees that it will not use,
distribute, transfer, or transmit the Products, Licensed Materials or
Information (even if incorporated into other products) in violation of U.S.
export regulations.  If requested by Supplier, AT&T shall sign written
assurances and other export-related documents as may be required for Supplier to
comply with U.S. export regulations.  This Section does not grant AT&T any
contractual right to Export Supplier's Products and Licensed Materials.  Such
right shall only be granted expressly in an applicable Supplemental Agreement.

                 6.2      PUBLICATION OF AGREEMENT.  The parties shall treat the
provisions of this Agreement and any Supplemental Agreement or any Order
submitted hereunder as Information subject to the restrictions on use and
disclosure set forth in Section 4.1, USE OF INFORMATION, except as reasonably
necessary for performance hereunder (including enforcement of Supplier's
obligations under the Pricing Agreement and AT&T's obligations under Exhibit 1
thereto) and except to the extent disclosure may be required by applicable laws
or regulations, in which latter case, the party required to make such disclosure
shall promptly inform the other prior to such disclosure in sufficient time to
enable such other party to make known any objections it may have to such
disclosure.  The party required to disclose information concerning this
Agreement, a Supplemental Agreement or Order to a third party in accordance with
the previous sentence shall take all reasonable steps to secure a protective
order or otherwise assure that the Agreement, Supplemental Agreement or Order
will be withheld from the public record.
  
 

                6.3      NOTICES.  All notices under this Agreement shall be in
writing (except where otherwise stated) by confirmed, facsimile, electronic mail
or similar communication, or by certified or registered mail.  Within ten (10)
days following the Effective Date, the parties will exchange the names and
addresses to whom the notices should be sent.  A notice shall be deemed to have
been given, if by electronic mail, facsimile or similar communication, on the
date it is


                                       39




sent, and, if by certified or registered mail, on the date it is deposited
postage prepaid.  Communications may be made orally between the parties when the
nature of the communication does not require written notice. In the event of a
change of address, written notice of such change shall be given promptly to the
other party.
  
                 6.4      ORDERING COMPANY'S RESPONSIBILITY.  (a)  Ordering
Company shall, at no charge to Supplier, provide Supplier with notice of site
conditions known to Ordering Company and such electrical and environmental
conditions, technical information, data, technical support or assistance as may
reasonably be required by Supplier to fulfill its obligations under this
Agreement, any Supplemental Agreement or Order. If Ordering Company fails to
provide the required conditions, technical information, data, support or
assistance, Supplier shall be discharged from its obligations to perform
hereunder for that Order.  Where Services are to be performed by Supplier in
buildings owned or controlled by Ordering Company, Ordering Company shall be
responsible for ensuring that the premises where the work is to be performed by
Supplier are accessible to Supplier and ready and suitable for the Services to
be performed in accordance with Supplier's reasonable site-preparation
conditions communicated in advance to Ordering Company. Such conditions
include, but are not limited to, (a) site readiness and (b) access to adequate
storage space for tools and other small items necessary for the work, working
space, personal facilities, heat, light, ventilation, telephone, electrical
current, and outlets, all provided within a reasonable distance of the area
where the work is to be performed, if available.
  
                 (b)      Supplier's representative shall have the right to
inspect the site prior to Service Start Date. If Ordering Company or its other
vendors or contractors fail to timely complete site readiness or if the work of
Ordering Company or its other vendors or contractors interferes with Supplier's
performance, the applicable Completion Date shall be extended as necessary to
compensate for such delay or interference and additional charges shall be
invoiced to recover the additional expenses incurred by Supplier as a result of
such failure or interference.  Moreover, should Ordering Company fail to comply
with the reasonable site-preparation conditions after Supplier provides Ordering
Company notice, Supplier may perform such work or furnish such items and charge
Ordering Company for them in addition to the prices otherwise charged by
Supplier for such Services.
  
                 6.5      SUPPLIER'S RESPONSIBILITY.  (a)  Supplier shall become
acquainted with conditions governing the delivery, receipt and storage of
materials at the site of the work so that Supplier will not interfere with
Ordering Company's operations.  For items other than those identified in Section
6.4, ORDERING COMPANY'S RESPONSIBILITY, above, storage space will not


necessarily be provided adjacent to the site of the work.  Therefore, Supplier
shall be expected to select, uncrate, remove and transport materials from the
storage areas provided.  Except to the extent that Supplier's property located
on Ordering Company's property is damaged or misappropriated by employees,
contractors or representatives of Ordering Company, Ordering Company is not
responsible for the safekeeping of such property.  When Supplier's property
located on Ordering Company's property is damaged or misappropriated by
employees, contractors, or representatives of Ordering Company, Ordering Company
shall be liable to Supplier for such damage or misappropriation.  Supplier shall
not stop, delay or interfere with


                                       40




Ordering Company's work schedule without the prior approval of Ordering Company.
Supplier shall provide and maintain sufficient covering and take any other
precautions necessary to protect Ordering Company's stock, equipment and other
property from damage due to Supplier's performance of the work.

                 (b)      Supplier recognizes that the continuity of Ordering
Company's telecommunications services is of paramount importance to Ordering
Company, and Supplier shall at all times exercise reasonable care to prevent
damage to Company's plant and shall not use any equipment or methods which
Ordering Company has informed Supplier, either in writing or through oral
directives at the work site, might endanger or interfere with its service.
  
                 6.6      EACH PARTY'S RESPONSIBILITY.  Each party shall be
entirely responsible for all persons that it furnishes working in harmony with
all others when working on the other party's premises or those of Ordering
Company's customers. Services performed by either party or its other vendors or
contractors shall not interfere with the other party's performance of services.
  
                 6.7      ASSURANCE OF SUPPLY.  (a) AT&T and Supplier will
jointly conduct regularly scheduled Life Cycle Management reviews for the
purpose of sharing information concerning current and future Product and support
requirements in order to permit both parties to make informed decisions
concerning such matters.  AT&T's priority is to assure the ongoing growth and
service capabilities of the network are satisfied.  In order to ensure the long
term viability of the network, AT&T will have the option to request sustained
manufacturing service for all Products and components that are used in the
network.
  
                 (b)      Supplier must provide written notification to AT&T
eighteen (18) months in advance of Supplier's intended date of DA of any Product
used in Ordering Company's network, or to substitute or replace such Product if
Form, Fit or Function is affected.  Supplier will provide nine (9) months
written notice with regard to GBCS Products not used in Order Company's network.
If Supplier's vendor terminates production of a Product and/or component of a
Product, Supplier will use reasonable efforts to provide the Products or
components or secure sources for such Products or components; provided however,
that Supplier reserves the right to provide a shorter notice in the event
suppliers of a Product or critical component terminates production or
maintenance of such items and no other sources for such items can be secured.
Within six (6) months of notification of DA, AT&T will provide written
notification to Supplier that it concurs with Supplier's decision or that it
intends to negotiate the terms, conditions and prices under which availability
shall be extended, provided that such Product and/or its components are
available to Supplier. Unless otherwise agreed to, the framework for that


agreement is that Supplier will be entitled to recover its costs of providing
continued availability, plus a reasonable profit.  Software DA is governed by
Section 9.20, NOTIFICATION OF DISCONTINUED AVAILABILITY OF SOFTWARE.
  
                 6.8      PUBLICITY.  Each party shall submit to the other a
proposed copy of all advertising wherein the name, trademark, code,
Specification or service mark of the other party

                                       41




or its Affiliates is mentioned. Neither party shall publish or use such
advertising without the other's prior written approval, which consent shall not
be unreasonably withheld or delayed.
  
                 6.9      RIGHT OF ACCESS/PERMITS AND APPROVALS.  Each party
shall have the right to enter the premises of the other party during normal
business hours with respect to the performance of this Agreement, subject to all
plant rules and regulations, security regulations and procedures and U.S.
Government clearance requirements if applicable.  No charge shall be made for
such access.  Reasonable prior notification shall be given when access is
required.  Ordering Company shall have the responsibility for obtaining all
state, local and federal approvals and permits prior to the commencement of the
work.  Any limitation of or delay in providing timely access may result in a
change of Supplier's schedule for performing its obligations hereunder and
additional charges to recover additional expenses incurred by Supplier as a
result of such limitations or delays.
  
                 6.10     FORCE MAJEURE.  Neither party shall be held
responsible for any delay or failure in performance to the extent that such
delay or failure is caused by a Force Majeure; provided, however, that Ordering
Company shall not be relieved by reason of such cause of its obligation to make
payments to Supplier. If any Force Majeure condition occurs, the party delayed
or unable to perform shall give prompt notice to the other party, stating the
nature of the Force Majeure condition and any action being taken to avoid or
minimize its effect.  The party affected by the other's delay or inability to
perform (hereinafter the "Affected Party") may elect to:  (a) suspend the
applicable Supplemental Agreement or Order for the duration of the Force Majeure
condition and (i) only to the extent reasonably necessary to maintain the normal
operation of the Affected Party's business, buy, sell, obtain or furnish
elsewhere the Product, Licensed Material or Services to be bought, sold,
obtained or furnished thereunder (unless such sale or furnishing is prohibited
under this Agreement, a Supplemental Agreement or an Order, in which event an
Ordering Company experiencing a Force Majeure condition shall bear Supplier's
reasonable costs (including inventory costs) incurred awaiting cessation of the
Force Majeure condition) and, at the option of the Affected Party, deduct from
any commitment the quantity bought, sold, obtained or furnished or for which
commitments have been made elsewhere and (ii) once the Force Majeure condition
ceases, resume performance under the applicable Supplemental Agreement or Order
with an option in the Affected Party to extend the period of such Supplemental
Agreement or Order up to the length of time the Force Majeure condition endured
and/or (b) when the delay or nonperformance continues for a period of at least
thirty (30) days, terminate, at no charge and without any liability, the
applicable Supplemental Agreement or Order or the part of it relating to
Products or Licensed Material not already shipped, or Services not already


performed.  Unless written notice is given within forty-five (45) days after the
Affected Party is notified of the Force Majeure condition, option (a) shall be
deemed selected.  Nothing contained herein or elsewhere shall impose any
obligation on either party to settle any labor difficulty.

                 6.11     INDEPENDENT CONTRACTOR.  All work performed by
Supplier, AT&T or an Ordering Company under this Agreement shall be performed as
an independent contractor and not as an agent of the other, and no persons
furnished by the performing party shall be considered


                                       42




the employees or agents of the other.  Each party is wholly responsible for
withholding and payment of all federal, state, and local income and other
payroll taxes with respect to its employees, including contributions from them
as required by law.

                 6.12     RELEASES VOID.  Neither party shall
require releases or waivers of any personal rights from representatives or
employees of the other in connection with visits to its premises, nor shall such
parties plead such releases or waivers in any action or proceeding.

                 6.13     SURVIVAL OF OBLIGATIONS.  The rights and obligations
of the parties which by their nature would continue beyond the termination,

                 6.14     GOVERNMENT CONTRACT PROVISIONS.  Ordering Company
shall identify in a request for proposed Supplemental Agreement if a Product,
Licensed Material or Service to be provided by Supplier is intended for use
under a government contract and if government contract flowdown provisions shall
apply to such procurement, with identification of such flowdown provisions.  In
such a case, Supplier will advise AT&T if it will submit a proposal, bid or
accept an Order on such basis and, if so, it will address its acceptance or
compliance with the flowdown terms and conditions in its proposal, bid or
Supplemental Agreement.  Orders placed in accordance with such proposal, bid or
Supplemental Agreement will be subject to the identified government contract
provisions as negotiated.  If an Order or Supplemental Agreement fails to
specify the inclusion of government flowdown clauses or is issued by AT&T
without the prior identification of government contract use or flowdown clauses
as provided above, Supplier shall have the right to terminate such Order or
Supplemental Agreement and collect from Ordering Company charges for expenses
incurred until the effective date of such termination.

                 6.15     QUALITY SYSTEM AUDIT.  (a) Supplier shall maintain a
compliant quality system that is subject to third party quality system audit
that shall include the following elements:

    

             (i)      Management Responsibility
                 (ii)     Quality System Principles

                 (iv)     Quality in Specification/Design

                 (vi)     Quality in Production
                 (vii)    Control of Production
                 (viii)   Product Verification
                 (ix)     Control of Measuring and Test Equipment


                                       43




                 (x)      Non-conformity
                 (xi)     Corrective Action
                 (xii)    Handling and Post-production
                 (xiii)   Quality Documentation and Records
                 (xiv)    Use of Statistical Methods

                 (b)      Such an audit shall assess the effectiveness and
documentation of the various elements that comprise a functioning quality
system. Supplier agrees that any deficiencies discovered in Supplier's quality
system as a result of the audit(s) shall be remedied by Supplier at Supplier's
expense.

                 6.16     ISO 9000. Supplier will undertake all reasonable
actions to become ISO 9000 registered.  Certain vintage Products are exempt from
this Section.  Such registration must be made by a third party registrar(s)
accredited in the following countries: United States or such other country as
may be designated in writing by AT&T or an Ordering Company.

                 6.17     UTILIZATION OF MINORITY AND WOMEN-OWNED BUSINESS
ENTERPRISES.  It is AT&T's policy that minority and women-owned business
enterprises ("MWBE's) as defined in Exhibit 6-1 shall have the maximum
practicable opportunity to participate in the performance of contracts. Supplier
agrees to use its good faith efforts to utilize MWBE's to carry out this policy
to the fullest extent consistent with the efficient performance of its business
and this Agreement.  In addition to these general conditions for MWBE support,
provided that Ordering Company will work with  Supplier to seek out MWBE's and
works with Supplier in the development of opportunities for the use of MWBE's,
Supplier agrees to (a) work with Ordering  Company to develop opportunities for
the utilization of MWBE's for first tier procurement of Supplier's Products,
Licensed Materials and Services by Ordering Company, (b) use its good faith
efforts to utilize MWBE's in support of this Agreement and strive to achieve the
portion of total expenditures for all Products, Licensed Materials and Services
purchased from Supplier equal to 5% of the value of Ordering Companies'
purchases of Products, Licensed Materials and Services from Supplier in 1996,
and strive to increase such percentage by 10% each of the following years of
this Agreement and (c) support Ordering Companies'  state and regional goals for
MWBE and service-disabled veterans spending in California and other
states/regions as may be defined in the future.  Supplier agrees to conduct a
program which will enable MWBE's to be considered fairly as subcontractors and
suppliers under this Agreement.  Supplier shall submit to AT&T periodic reports
of work with known MWBE's in the form of Exhibit 6-1 in such manner and at such
time (not more than quarterly) as AT&T's representative may prescribe.  Such
periodic reports shall state separately for MBE's and WBE's the subcontracted
work which is attributable to Ordering Companies.  In instances where direct


correlation cannot be determined, such MWBE payments may be established by
Supplier comparing Ordering Company's payments to Supplier, in that period, to
total payments to Supplier from all of its customers, in that period, and then
arriving at Ordering Company's apportionment of such MWBE payments.  Nothing in
this clause shall affect or diminish Supplier's obligations as set forth in the
assignment and subcontracting provisions.


                                       44

  



                 6.18     ASSIGNABILITY.  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. Any
attempted assignment in contravention of this clause shall be void and
ineffective.  Nothing shall preclude a party from employing a subcontractor in
carrying out its obligations under this Agreement; provided, however, that if
Supplier uses a subcontractor to perform a material service or obligation under
this Agreement, such use will be subject to AT&T's written consent.  Supplier's
use of such subcontractor shall not release Supplier from its obligations under
this Agreement.  Notwithstanding the foregoing, Supplier shall have the right to
assign this Agreement and to assign its rights under this Agreement, in whole or
in part, to any present or future Affiliate or to any entity which purchases
from Supplier the operating asset(s) utilized by Supplier to fulfill its
obligations hereunder, subject to AT&T's written consent, which consent shall
not be unreasonably withheld; provided, however, that in any such event Supplier
shall not be released from its obligations hereunder and shall indemnify, defend
and hold harmless each Ordering Company for all losses or damages arising in
connection therewith, including from any breach of this Agreement by such
assignee.  The notice of assignment shall state the effective date thereof.

not be released from obligations.  For purposes of this clause, the "Agreement"
includes this Agreement, each Supplemental Agreement, each Order and any other
subordinate agreement placed under this Agreement.

                 6.19     GOVERNING LAW.    Except as set forth in Section

but not limited to,  those relating to the environment, health, and safety. Each
Party agrees to indemnify, defend (at the other party's request) and save

their officers, directors and employees from and against any losses, damages,
claims, demands, suits, liabilities, fines, penalties and expenses (including
reasonable attorney's fees) that arise out of or result from (i)  failure to do
so or (ii)  activity, duty or status of such party that triggers any obligation
to investigate or remediate environmental contamination.



                 6.21     RECORD RETENTION.  Ordering  Company agrees to keep
true and accurate records with regard to its use of Supplier's Licensed

notice in writing to Ordering Company.  Supplier shall bear the cost of such
auditing.


                                       45




                 6.22     NON-WAIVERS.  The failure of either party at any time
to enforce any right or remedy available to it under this Agreement or otherwise
with respect to any breach or failure by the other party shall not be construed
to be a waiver of such right or remedy with respect to any other breach or
failure by the other party.

                 6.23     THIRD PARTY BENEFICIARIES.  Except as otherwise
provided in Section 1A.7, PURCHASES BY AT&T'S AFFILIATES, of this Agreement or

                 6.24     SEVERABILITY.  If any provision of this Agreement or
any Supplemental Agreement or the application thereof to any person or
circumstance is determined by a court of competent jurisdiction to be invalid,
void or unenforceable, the remaining provisions hereof or thereof, or the
application of such provision to persons or circumstances or in jurisdiction
other than those as to which it has been held invalid or unenforceable, shall

                              PURCHASE OF PRODUCTS

                 8.1      GENERAL.  The provisions of this Article 8 shall be
applicable to the purchase of Products from Supplier. If Software is also to be
licensed for use on a purchased Product, or if a Product is also to be
engineered or installed by Supplier, the provisions of Articles 9 and 10 shall

                 8.2      PRODUCT WARRANTY.   (a) Supplier warrants to Ordering
Company only, that:

                          (i)     As of the date title passes, Supplier will
         have the right to sell, transfer, and assign such Products and the
         title conveyed by Supplier shall be good and Products shall be
         delivered free from any security interests or any other liens or
         encumbrances;

                          (ii)    Upon shipment or, if installed by Supplier
         upon Acceptance, Supplier's Manufactured Products will be new (except
         if manufactured discontinued, or with Ordering Company's approval),
         free from defects in material, workmanship, and design (except to the
         extent (A) designed, in whole or in part, by Ordering Company or
         persons furnished by Ordering Company; or (B) such design defects are
         caused by the presence in Supplier's Manufactured Product of substitute
         components of Ordering Company's selection and not recommended by
         Supplier), and will conform to Supplier's Specifications or any other
   

      agreed-upon Specifications referenced in the Order for such Products;
         and

                          (iii)   With respect to Vendor Items, Supplier, to the
         extent permitted, does hereby assign to Ordering Company the warranties
         given to Supplier by its vendor


                                       48




         of such Vendor Items.  Such assignment will be effective on the date of
         shipment of such Vendor Items.  With respect to Vendor Items
         recommended by Supplier in its Specifications for which the Vendor's
         warranty cannot be assigned to Ordering Company, or if assigned, less
         than sixty (60) days remain of the Vendor's warranty at the time of
         assignment, Supplier warrants for sixty (60) days from date of shipment
         or if installed by Supplier from Acceptance that such Vendor's Items
         will be free from defects in material and workmanship and will conform
         to Supplier's Specifications or any other agreed-upon Specification
         referenced in the Order for such Products.

                          (iv)    Neither inspection, Acceptance, nor payment
         shall affect or reduce the term of any warranty.

                 (b)      The Warranty Period for a Product is set forth in
Exhibit 8-1.  The Warranty Period for a Product or part thereof repaired under
this Warranty is the period indicated in Exhibit  8-1.

                 (c)      If, under normal and proper use during the applicable
Warranty Period, a defect or nonconformity is identified in a Product furnished
by Supplier, Ordering Company shall notify Supplier in writing of such defect or
nonconformity promptly after Ordering Company discovers such defect or
nonconformity and follow Supplier's instructions regarding the return of
defective or nonconforming Product.  With respect to a defect or nonconformity
of Products to Supplier's Specifications or any other agreed upon Specification
referenced in the Order for such Products, Supplier shall take the following
action promptly:

                          (i)     Within the first sixty (60) days after (aa)
         installation completion of a Product, if Supplier has installed the
         Product or (ab) delivery, if Supplier is not installing the Product, if
         Ordering Company notifies Supplier of a defect or nonconformity of
         Products to the Specifications, that does not appear to be curable
         through repair or replacement within a reasonable time period, Ordering
         Company will be entitled, at its option, to a refund of the Product's
         purchase price and installation charges and the associated Licensed
         Materials charges.  Should Ordering Company seek such a refund, it will
         provide Supplier such cooperation as necessary to enable Supplier to
         remove the Product from Ordering Company's premises, if necessary.  In
         the event of such refund, Ordering Company may also return for credit
         any other Products intended for use with the defective Product that
         cannot be applied to another use by Ordering Company and may cancel,
         without liability for cancellation charges, any pending Orders for such
         Product.



                          (ii)    After sixty (60) days from (aa) installation
         completion of a Product, if Supplier has installed the Product or (ab)
         delivery, if Supplier is not installing the Product, with respect to a
         defect or nonconformity of Products to Supplier's Specifications,
         Supplier shall take the following action promptly:


                                       49




                                  (A)      Supplier, at its option, shall
         attempt first to repair or replace such Product without charge or, if
         not feasible, provide a refund or credit based on the original purchase
         price, installation charges paid by Ordering Company if installed by
         Supplier, and the associated Licensed Materials charges.  Ordering
         Company must return Product to Supplier for repair and replacement,
         except as noted in Sections 8.2 (c) (ii) (B) and (C).  In the event of
         such refund, Ordering Company may also return for credit any other
         Products intended for use with the defective Product that cannot be
         applied to another use by Ordering Company and may cancel, without
         liability for cancellation charges, any pending Orders for such
         Product.

                                  (B)      Supplier, in the case of any service
         affecting defect, shall either (1)  repair such defect in the field
         using best reasonable efforts to avoid any service interruption; or (2)
         immediately replace the defective Product, Licensed Material, or
         Service with a working replacement, at Supplier's expense, for the time
         that it takes the original Product, Licensed Material, or Service to be
         repaired.  At Ordering Company's option, Ordering Company may elect to
         retain the replacement Product, Licensed Material, or Service if
         substitution of the original after repair could cause a further service
         interruption.  Where Supplier has elected to repair or replace a
         Product (other than Cable and Wire Products) which has not been
         installed by Supplier and Supplier ascertains that the Product is not
         readily returnable by Ordering Company, Supplier will repair or replace
         the Product at Ordering Company's site.  For the purposes of Sections
         8.2 (c) (ii) (B) and (C) and Section 8.2 (d), Cable and Wire Products
         shall mean fiber optics and associated products and copper cable and
         associated products, including, but not limited to, interbay cable,
         closures, arrays, and mounts.

                                  (C)      With respect to Cable and Wire
         Products which Supplier has ascertained are not readily returnable for
         repair, whether or not installed by Supplier, Supplier may elect to
         repair the Cable and Wire Products at Ordering Company's site.

                 (d)      If Supplier has elected to repair or replace a
defective Product, Ordering Company is responsible for removing and reinstalling
the Product and, in addition, for on-site repair or replacement of cable and
wire products, Ordering Company must make the Product accessible for repair or
replacement, and is responsible to restore the site.

                 (e)      Products returned for repair or replacement will be


accepted by Supplier only in accordance with its instructions and procedures for
such returns.  The transportation expense associated with returning such Product
to Supplier shall be borne by Ordering Company.  Supplier shall pay the cost of
transportation of the repaired or replacing Product to the destination
designated by Ordering Company.  The same Product or part shall not be returned
by Supplier to Ordering Company with the notation no-trouble-found (NTF) on more
than two (2) occasions.  On the third occasion that a Product or part has been
classified by Supplier as NTF, the Product or part shall be returned to Supplier
and shall become Supplier's property. Supplier shall ship a new, refurbished, or
reconditioned replacement to Ordering Company for the returned Product or part
at no charge for that Product under warranty.  For out of warranty


                                       50




Product, Supplier shall ship a new, refurbished, or reconditioned replacement to
Ordering Company for the returned Product or part at Supplier's current
negotiated price for the production equipment element/component.

                 (f)      The defective or nonconforming Products or parts which
are replaced shall become Supplier's property. Supplier may use either new,
remanufactured, reconditioned, refurbished, or functionally equivalent Products
or parts in the furnishing of repairs or replacements under this Agreement.
Unless otherwise agreed or unless unavailable, Supplier shall use new components
in the repair of Products.

                 (g)      If a Product for which warranty Service is claimed is
not defective or is in conformance, Ordering Company shall pay Supplier's costs
of handling, inspecting, testing, and transporting, and, if applicable,
reasonable traveling and related expenses as referenced in Section 3.1 (g),
PRICES.

                 (h)      Supplier makes no warranty with respect to defective
conditions or nonconformities resulting from the following:  Ordering Company
modifications, misuse, neglect, accident or abuse, improper wiring, repairing,
splicing, alteration, installation, storage or maintenance other than by
Supplier, use in a manner not in accordance with Supplier's or vendor's
Specifications or operating instructions or failure of Ordering Company to apply
previously applicable Supplier modifications and corrections which were
available without extra charges and which Ordering Company had had reasonable
opportunity to apply.  In addition, Supplier makes no warranty with respect to
Products which have had their serial numbers or month and year of manufacture
removed or altered and with respect to expendable items, including, without
limitation, fuses, light bulbs, motor brushes, and the like.

                 (i)      THE FOREGOING PRODUCT WARRANTIES ARE EXCLUSIVE AND
ARE
IN LIEU OF ALL OTHER EXPRESS AND IMPLIED WARRANTIES, INCLUDING BUT
NOT LIMITED
TO WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE, EXCEPT

Ordering Company such as, but not limited to, distinctive marks conforming to
Ordering Company's Serialization Plan.  Charges, if any, for such additional
identification marking shall be as agreed upon by Supplier and Ordering Company.
This clause does not reduce or modify Supplier's obligations under Section 4.4,
TRADEMARKS, included in this Agreement.

                 8.14     PERIODIC PRODUCT QUALIFICATION REVIEWS.  Supplier
shall conduct periodic product qualification ("PPQ") reviews to ensure that the

                 8.15     MAINTENANCE/POST WARRANTY.  Supplier may offer various
programs which provide services beyond the warranty repairs above.  At Ordering
Company's option, Ordering Company may purchase these Repair Service and Return
("R/SAR"), Spares Exchange Service ("SES"), and other offerings at prices, terms
and conditions to be mutually agreed upon.

                 8.16     PLANNING INFORMATION FOR ORDERS FOR COMMERCIALLY
AVAILABLE PRODUCTS. (a)  This planning information addresses the process for all
Orders of Supplier's commercially available Products.   It is not applicable to
custom Products  or special arrangements on such things as inventory or
manufacturing (i.e., any custom or legacy products requiring unique procedures,
such as NGLN, DDM1000, FT-Series G and projects such as Customer Connectivity).
Special Product or unique arrangements will require a Supplemental Agreement to
document the agreements made specifically for that Product or project only.

                 (b)      Supplier and Ordering Company shall identify Products
or technologies that will require special arrangements and for which
Supplemental Agreements must be negotiated.

                 (c)      Ordering Company  will provide to Supplier on a
monthly basis via the Customer Demand Planning (CDP) mechanized system, a
forecast of Product requirements consisting of funded, unfunded, and a
projection of unforecasted demand.  This forecast is considered unconstrained
and will be provided for a rolling twelve (12) months as well as an aggregate
forecast for the subsequent year.  It will represent forecasted demand by fiscal
month.

                 (d)      A current listing of Products that are presently
forecasted by Network Services Division/Inventory Management ("NSD/IM") will be
mutually agreed upon and updated periodically as the scope of the forecasting
process changes.  Forecasts furnished by Ordering Company will eventually
encompass all of the network Product requirements for Ordering Companies.

                 (e)      Orders will be placed within Supplier's planning
interval documented in Exhibit 2-1, Planning Intervals, to the extent possible,
and will constitute a commitment to buy.  Ordering Company will compare the
monthly forecast with the semi-annual planning forecast being provided in April
and September, and will reconcile the two accordingly.  In the future, if the
frequency of these forecasts changes, a similar reconciliation will be performed
on all Product elements that are provided in the planning forecasts.  Ordering
Company and Supplier will review Ordering Company's forecasting accuracy
quarterly with the goal of obtaining 80% forecasting accuracy.  Ordering Company
will work with Supplier to provide Product level requirements on a monthly basis
especially for those forecasts within the six (6) month window as part of the


rolling forecast.

                 (f)      CUSTOMER DEMAND PLANNING (CDP).  Should Ordering
Company request a programming change to the CDP system that would benefit
external users of the CDP system, Supplier shall make such modification at no
cost to Ordering Company.  If Ordering Company has a request for a modification
to the CDP system that is specific to Ordering Company's needs,


                                       56




such modification to the system shall be made at a cost mutually agreed upon by
Ordering Company and Supplier.  Supplier shall provide Ordering Company with CDP
system support via the 1-800-CDP-8845 Hotline at no cost to Ordering Company.

                 (g)      METRICS.  Ordering Company and Supplier agree to
monitor forecast accuracy on a monthly basis.  Forecast accuracy measurements
shall be based upon a two month lead time for each forecasted item.  CDP shall
be the vehicle for gathering data on forecast accuracy and shipping performance.
Ordering Company will monitor its forecasts and seek to achieve improvements in
accuracy as described in Exhibit 8-3.  Supplier will monitor and seek to achieve
improvements on performance to customer requested completion date (CRCD), and
performance to published order intervals. This is an informal process and does
not imply penalty for non-performance.  The 1996 metric goals are set forth in
Exhibit 8-3.  Joint goals and metrics for future years will be mutually
negotiated for continuous improvement.

                 (h)      FORECASTING PROCESS MONITORING.  Forecasting Process
Performance Goals will be monitored on an ongoing basis by the Inventory
Management Process Management Team and the Forecasting Quality Improvement Team.
Additional meetings to review forecasting specifics may be scheduled as needed
by either Ordering Company or Supplier.

     redirect its efforts being expended on a lower Severity Level condition,
     Supplier shall notify Ordering Company that there will be a delay in
     correcting the lower Severity Level condition.

                     (H) PROBLEM MANAGEMENT - Supplier shall perform procedures
     and actions upon written or oral request of Ordering Company to investigate
     and develop the resolution of a reported condition in a manner that
     provides Ordering Company a single interface. This service is performed
     only for Products covered under the Maintenance Service Order.

                     (I) MANAGEMENT NOTIFICATION - Supplier will observe the
     following escalation procedures:

                         (1) SEVERITY LEVEL ONE - In the event of a Severity
     Level One condition that is still unrestored four (4) hours after the
     condition is reported, Supplier will notify Supplier's supervisory
     management or next level of expertise of the unrestored condition. If the
     condition is still unrestored within eight (8) hours after the condition is
     reported, the next higher level of Supplier supervisory management or level
     of expertise will be notified of the unresolved condition. Once the highest
     level of expertise is reached, no further escalation will occur.

                         (2) SEVERITY LEVEL TWO - In the event of a Severity
     Level Two condition that is still unrestored twelve (12) hours after the
     condition is reported, Supplier will notify Supplier's supervisory
     management of the unrestored condition.

                     (J) SERVICE PERFORMANCE REPORTS (SPR) - Supplier will
     provide quarterly reports of Supplier's performance against the objectives
     stated in this Article 10.

     provide Ordering Company Notification Bulletins to Ordering Company on an
     as needed basis. 

                     (L) ON-SITE ASSISTANCE - At Ordering Company's request and
     as agreed to by Supplier, a Supplier's engineer may be dispatched to
     Ordering Company's site for resolution of a problem. If the problem is not
     caused by a Designated Processor covered by this Agreement, On-Site


     Assistance will be billed at minimum of eight (8) hours a day at the then
     current Supplier time and material (T&M) rate. 

                                       75




     Reasonable travel and living expenses incurred by Supplier as referenced in
     Section 3.1(g), PRICES, will also be billed.

               (ii)  PERFORMANCE METRICS & OBJECTIVES. (A) The Performance
     Metrics described in this Section shall apply to Products and Licensed
     Software covered under the Preferred and Standard Service Levels as
     described in Section 10.2(c)(ii)(E) above. The problem must be reproducible
     at either Supplier's location or on Ordering Company's system verifiable by
     Supplier. The Severity Level of any problem shall be determined by Ordering
     Company; however, if during resolution Supplier determines that the
     Severity Level of the problem claimed by Ordering Company to be inaccurate,
     the Severity Level may be changed by Supplier upon mutual agreement with
     Ordering Company. Ordering Company requests which do not go through
     Supplier's Call Receipt function will be excluded from the Performance 
     Metrics.

                     (B) Initial Response. During the term of a fixed-term
     Maintenance Service Agreement, and upon expiration of any product warranty,

     Response time will be validated through the use of the Service Performance
     Report (SPR). Ordering Company requests which do not go through Supplier's
     Call Receipt function will be excluded from the Performance Metrics.

                     (C) Service Restoration for Service Levels One and Two
     shall be mutually agreed to by Ordering Company and Supplier, and
     documented in the Maintenance Service Agreement. Restoral time will be
     validated through the use of the Service Performance Report (SPR).

                     (D) Resolution of Defect and Service Severity Levels One
     through Four shall be mutually agreed to by Ordering Company and Supplier,
     and documented in the Maintenance Service Agreement. Resolution times will
     be validated through the use of the Service Performance Report (SPR).

In addition, for 4ESS switch and 5ESS switch, the Switching Software Support
Plan (SSP), defines how the level of support changes with time upon the
introduction of new base releases. Exhibit 10-2 further explains the support
service that will be offered during each of the life cycle phases.

         10.10 ELIGIBILITY FOR MAINTENANCE SERVICE. (a) Products and Software
furnished and installed by Supplier are eligible for Maintenance Service without
initial evaluation by Supplier provided the Service commences not later than the
end of the Warranty Period. Unless otherwise agreed by Supplier in writing,
Maintenance Service for Software shall only be available for the generic that is
current at the time that such Service is ordered and the immediately preceding
generic, as well as a generic where the term of warranty is still in effect.

         (b)  In all other situations, the Products and Software shall not be
eligible for Maintenance Service until Supplier, at its option, has made an
initial evaluation to determine whether modifications are required to make the
Product or Software eligible. If, in Supplier's judgment, modifications are
required for this purpose, Supplier will provide a written estimate based on
standard rates to Ordering Company for making such modifications. Upon Ordering
Company's written Acceptance, Ordering Company will be billed at Supplier's then
standard rate for such evaluation and any such modifications furnished by
Supplier. Software will not be eligible for Maintenance Service unless Supplier
determines that the Software is in good working order in accordance with its
Specifications and can be maintained in such condition.

         10.11 ORDERS FOR MAINTENANCE SERVICES. Ordering Company shall place
Orders for Maintenance Services, indicating the Level of Service to be provided
for each Product upon commencement of the Order. The Level of Service chosen
shall remain in effect without change for the contract period covered by the
Order. All installations of each Product and each release of Software must be
served at the same Level of Service.

         10.12 PRICES. Sixty (60) days prior to the expiration of any fixed-term
Service Order, Supplier will, at Ordering Company's request, submit a price for
the renewal of the Service. Charges for time-and-material Maintenance Service
shall be determined at Supplier's applicable time and material rates in effect
at the time an Order for such Service is accepted and will be based on the total
work-hours (which includes travel time) expended on the job, and actual travel
expense. Such charges shall be based on a minimum number of hours.

         10.13 PERIODS OF MAINTENANCE SERVICE. Maintenance Service will be
provided in accordance with the Level of Service specified in an Order.

         10.14 MAINTENANCE SERVICE EXCLUSIONS. (a) Unless expressly agreed by


Supplier, Maintenance Services to be provided under this Article do not include:

               (i)   Performing preventive maintenance;
               
               (ii)  Making corrections to user-defined reports;

                                       77




               (iii) Making Specification changes or performing Services
     connected with relocation of the Product;

               (iv)  Service which is impractical for Supplier to render because
     of changes not authorized by Supplier in the Designated Product processor,
     hardware configuration, Supplier's Product or the Product environment in
     which Supplier's Product operates;

               (v)   Modification or replacement of Product, repair of damage, 
     or increase in Service time caused by:

                     (A) Failure to continually provide a suitable operational
     environment with all facilities prescribed by the applicable document
     including, but not limited to, the failure to provide, or the failure of,
     adequate electrical power, air conditioning, or humidity control;

                     (B) The use of the Product in a manner not in accordance
     with its Specifications, operating instruction or license-to-use;

                     (C) Accident; disaster, which shall include, but not be
     limited to, fire, flood, earthquake, water, wind and lightning;
     transportation; neglect or misuse; pest damage; or power failures or surges
     from sources external to the Product;

                     (D) Modifications, maintenance, or repair performed by a
     party other than Supplier;

                     (E) The conversion from one Supplier Software release to
     Supplier's subsequent Software Release, or the failure of Ordering Company
     to apply previously applicable modifications and corrections offered by
     Supplier;

                     (F) Attachment of unspecified or non-approved products to
     the Product, including updates from manufacturers of third party Software
     and Software not licensed by Supplier, or Designated Processors that have
     not been certified by Supplier, or failure of a processor or other
     equipment or software not maintained by Supplier, or failure of removable
     or rotating storage media.

               (vi)  Problem Management, as follows:

                     (A) Database Problems - If the condition is mutually
     determined to be the result of corruption of the Software Product data
     base, and such corruption is not the direct result of the Product, the


     condition will be referred back to Ordering Company for resolution. At
     Ordering Company's request, and at Supplier's option, Supplier may prepare
     a proposal for billable corrective action to correct Ordering Company's
     database. However, if corruption is the result of, or caused by another of

                                       78




     Supplier's Products or Services, Supplier shall initiate Problem Management
     regardless of whether such Software Product is covered under an Order.

                     (B) Hardware/Firmware Problems - When a condition has been
     isolated to a problem in hardware or Firmware not covered under this
     Agreement, the condition will be referred back to Ordering Company for
     disposition under whatever arrangements Ordering Company may have for such
     hardware or Firmware.

                     (C) Other/Interfacing Problems - If the condition is
     determined mutually to be caused by systems other than the Products covered
     under the existing Order, including, but not limited to, systems which
     interface with the Product, the condition will be referred to Ordering
     Company for corrective action unless such other system has been furnished
     by Supplier, in which case, Supplier shall initiate Problem Management.
     However, if a defect is identified with Software or Products covered by the
     Order which is documented or advertised to interface or work with other
     systems, hardware, Products or Software, Supplier shall conduct restoral
     and correction procedures as required for a defect and not as Problem
     Resolution Management.

                     (D) Additional Services - Additional services, including
     but not limited to custom feature development, training, planning sessions,
     and other value-added services, are not included in the fees paid under
     this Agreement. Such services may be available through a Firm Price Quote
     (FPQ).

         (b)   At the request of Ordering Company, Supplier, at its option, may
perform Maintenance Services in the excluded conditions listed above, at
Supplier's rates and terms in effect at the time of such request.

         10.15 ORDERING COMPANY RESPONSIBILITIES. In addition to the

Company agrees to install the corrections or replacements provided under this
Agreement within a reasonable period of time. Ordering Company's failure to
install emergency fixes, work-arounds, patches or releases will cause the
Software Product to be considered non-standard until all such fixes are
installed, unless Ordering Company has previously notified Supplier of problems
with such emergency fixes, work-arounds, patches or releases.

         10.18 MAINTENANCE SERVICES WARRANTY. Supplier warrants to Ordering
Company that Maintenance Services will be performed in a professional manner and
in accordance with Supplier's specifications or those referenced in an Order and
with accepted practices in the community in which such Services are performed,
using material free from defects except where such material is provided by
Ordering Company. If the Services prove to be not so performed and if Ordering
Company notifies Supplier, within the period of time equal to the repaired
Product warranty period (Exhibit 8-1), of the Product being repaired, or six (6)


months, whichever is less, commencing on the date of Acceptance of the Service,
as identified in writing by Supplier, Supplier, at its option, either will
correct the defect or nonconforming Service for which Supplier is responsible or
render a full or prorated refund or credit based on the 

                                       82




original charge for the Services. After the corrective action, Ordering Company
shall have the right to Acceptance of the corrective work done.

                 11.3     ORDERING COMPANY FURNISHED MATERIALS.  (a) All
material furnished by Ordering Company shall be delivered to Supplier at
storeyards or other locations to be mutually agreed upon; and, Supplier shall
have charge of, and be responsible for, all the material upon and after its
delivery to Supplier and shall return to Ordering Company all the material not
required for the completion of the Work, excluding waste.

                 (b)      Supplier shall replace all Ordering Company furnished
materials which are lost or damaged while in the custody of Supplier.
Replacement materials shall be of a type and quality substantially equal to the
original materials, acceptable to the Engineer, and shall be obtained promptly
to prevent delay of the Work.



                 (c)      Supplier shall rehandle and reload, if required, all
Ordering Company furnished materials and equipment which have been rejected by
Supplier.

                 (d)      Ordering Company shall reimburse Supplier for all its
material shipping and handling expenses associated with:


                                       84




                          (i)     The return and/or replacement of defective 
         Ordering Company provided materials.

                          (ii)    The return of excess materials resulting from
         the termination of an Order or a decrease in the quantities of
         materials required to complete a Work Order for reasons other than
         breach of contract or material non-performance by Supplier.

                          (iii)   The return of materials provided by Ordering
         Company in excess of those requested by Supplier in the Bill of
         Materials.

                 (e)      Unless expressly stated to the contrary, the Price
does not include costs for any Ordering Company furnished material nor does it
include any Supplier charges for re-engineering, reinstallation, modification,
or repair Services to Ordering Company furnished material.  New or used
material (if any) furnished by Ordering Company shall be in such condition that
it requires no repair and no adjustment or test effort in excess of that normal
for new material. Ordering Company assumes all responsibility for the proper
functioning of such material under normal conditions of use and/or when
properly installed.  Ordering Company shall also provide the necessary
information for Supplier to properly install such material.

                 11.4     ORDERING COMPANY OBLIGATIONS.  (a) On or before the
start date, at its own expense, Ordering Company will complete or provide, or
arrange for the completion or provision, of all of the following "Ordering
Company Obligations" set forth or referred to in this Section 11.4, ORDERING
COMPANY OBLIGATIONS.  Ordering Company shall fulfill all obligations applicable
to Ordering Company-owned or -controlled buildings set forth in Section 10.7,
CONDITIONS OF INSTALLATION AND OTHER SERVICES PERFORMED ON
ORDERING COMPANY'S
SITE, above, including but not limited to provision of adequate Access to
Building and Site, General Building Conditions, Repairs to Buildings, Openings
in Buildings, Floor Space and Storage Facilities and Building Grounds.  In
addition to Ordering Company's obligations in the Specifications, Ordering
Company shall comply with the following:

                          (i)     CONSULTANTS FOR SPECIAL SITES - Except as
         otherwise provided in Section 11.18, ARCHAEOLOGICAL SITES;
         ENVIRONMENTAL PROTECTION, Ordering Company shall provide, or, at
         Ordering Company's option, shall authorize Supplier to provide, any
         consultants for special considerations, including, but not limited to,
         biologists to evaluate endangered species impacts or archaeologists to
         evaluate historically sensitive sites and qualified experts to


         evaluate environmentally hazardous conditions.  In the event that
         Supplier provides such consultants, Ordering Company shall reimburse
         Supplier for such consultant costs on a Lump Sum Price basis; and

                          (ii)    EASEMENTS, PERMITS, AND RIGHTS OF WAY -
         Unless otherwise required by applicable ordinances, codes or statutes,
         any necessary highway permits, construction permits, easements,
         joint-use or right of way grants shall be obtained and paid for by
         Ordering Company and Ordering Company shall file, or have filed, the

                                       85




         necessary papers (collectively, the "Ordering Company Permits").
         Ordering Company Permits and corresponding permit applications, if
         necessary, are included in the Agreement Documents.  If a permit is
         unavailable at the time of issue of the Agreement Documents, the permit
         application only will appear.  Permits which are not available at the
         time of issue of the Agreement Documents will be provided to Supplier
         prior to the Start Date specified in each Work Order.  When permits not
         listed in the Agreement Documents are obtained by Ordering Company, a
         copy will be provided to Supplier.

                          (iii)   Railroad flagmen and/or inspectors required
         to be on the Site as a condition of an easement permit or right of way
         or other railroad requirement, will be provided by Ordering Company at
         no cost to Supplier.

                 11.5     WORK ORDERS; CHANGES.  (a) Ordering Company shall
submit Work Orders to Supplier utilizing Ordering Company's form.  Each Work
Order and Field Order shall contain or refer to a document containing the
information necessary for Supplier to fulfill the Work Order, including, but
not limited to, the information called for by Section 2.1, ORDERS, above, a
reference to this Agreement, Special Conditions, a Start Date, Completion Date
and a Completion Schedule.  If such work items have been mutually agreed upon
in a writing signed by the parties (e.g., a Supplemental Agreement or a
previously issued Work Order), then Supplier shall proceed to fulfill the Work
Order (i.e., the Work Order shall function as a notice by Ordering Company for
Supplier to proceed with the Work).  If such items have not been agreed upon,
Supplier may reject the Work Order or propose changes to the Work Order.  If
the parties are unable to agree, the Work Order shall be deemed abandoned.

                 (b)      Each Work Order and Field Order shall be subject to
the terms and conditions of this Agreement which shall control over any
conflicting provisions in such Work Order.

                 (c)      Changes by Ordering Company to an accepted Work Order
shall be treated as a separate Work Order unless the parties expressly agree
otherwise.  In addition, subject to Section 11.18, ARCHAEOLOGICAL SITES;
ENVIRONMENTAL PROTECTION, Supplier may identify additional changes to the Work
which must be performed due to certain conditions, as set forth in Section
11.8, LOCAL CONDITIONS; DIFFERING SITE CONDITIONS below.  If any such change
affects Supplier's ability to meet its obligations under the original Work
Order, any Price or Completion Date quoted by Supplier with respect to such
original Work Order is subject to change.  All such changes must be approved in
writing by authorized representatives of both parties using Ordering Company's
Form.



                 (d)      Minor changes may be made by means of a Field Order.

                 11.6     PLANT PROTECTION; UNDERGROUND FACILITIES.  (a)
Supplier shall adhere to the applicable MOP with respect to Ordering Company's
underground facilities.

                                       86




                 (b)      Ordering Company has made minimal efforts to identify
existing utilities by field surveys and utility records research.  Existing
underground and aerial utilities within the construction limits of the Work are
indicated on the Drawings only to the extent information on such utilities has
been made available to, or discovered by, the Engineer in the performance of
the design work.  Except to the extent that the information contains a material
misrepresentation of fact, the Engineer and Ordering Company expressly disclaim
all responsibility for the accuracy and completeness of the information
indicated.  Supplier shall conduct its operations on the basis that underground
and aerial utilities may exist which are not indicated on the Drawings.

                 (c)      Supplier shall be responsible for locating and
identifying, except for Ordering Company's facilities or structures, all
existing utilities or structures within the construction limits of Work and
elsewhere where Supplier's construction operations may subject the utilities
or structures to damage.  This shall be done prior to the performance of the
Work.  All information relative to the above shall be recorded and incorporated
into the records in a manner reasonably acceptable by the Engineer.

                 (d)      For Ordering Company facilities or structures,
Supplier shall adhere to the "One Call" procedure, as set forth in the
Specifications.

                 11.7     PROTECTION OF PUBLIC AND PUBLIC PROPERTY. Subject to
any more stringent requirements of Section  11.18, ARCHAEOLOGICAL SITES;
ENVIRONMENTAL PROTECTION, and Section 6.20, COMPLIANCE WITH LAW:

                 (a) Supplier shall in the performance of the Work exercise
reasonable measures to minimize inconvenience to the public and shall use its
reasonable efforts to preserve and protect all trees, shrubs, grass, or other
vegetation on or adjacent to the right of way or  Site which do not
unreasonably interfere with the Work.  Unless otherwise required by Ordering
Company's Representative, Supplier shall restore all such property which may
be disturbed in the execution of its Work to its former visible condition.

                 (b)      In accordance with Supplier's standard procedures,
all pavement, surfacing, driveways, curbs, walks, buildings, utility poles, guy
wires, fences, and other surface structures affected by Supplier's Work,
together with all sod and shrubs in yards and parking areas, shall be
substantially restored to their original visible condition, whether within or
outside the easement. Supplier shall be responsible for (i) making reasonably
satisfactory and acceptable arrangements with the owner of, or the agency or
authority having jurisdiction over, the damaged property concerning its repair
or (ii) replacement, or payment of reasonable costs incurred in connection with


such damage caused by Supplier or its Subcontractors.

                 11.8     LOCAL CONDITIONS; DIFFERING SITE CONDITIONS.  (a)
Upon execution of a Work Order, Supplier admits to being reasonably informed as
to the nature and locations of the Work set forth therein; provided, however,
that in all cases, except as otherwise provided in Section  11.18,
ARCHAEOLOGICAL SITES; ENVIRONMENTAL PROTECTION, Differing


                                       87




Site Conditions shall be the basis for a Change Order and additional
compensation as set forth  below in this Section 11.8.

                 (b)      Delays, Additional Work, or extra costs may result
from Differing Site Conditions of which neither Ordering Company nor Supplier
should reasonably have had knowledge at the time of the effective date of the
earlier of the Supplemental Agreement, the Work Order and the Change Order.  In
such case:

                          (i)     Supplier shall, promptly and before Differing
         Site Conditions are disturbed, notify the Engineer in writing by means
         of  the Ordering Company Change Order Form of such conditions;

                          (ii)    After receiving notice from Supplier, the
         Engineer shall promptly investigate the Differing Site Conditions,
         and, if in his reasonable judgment, such conditions exist, the
         Ordering Company Representative shall by means of a Change Order make
         an equitable adjustment to the Price and the Completion Schedule, as
         agreed by Supplier; and

                          (iii)   No claim of Supplier for an equitable
         adjustment because of Differing Site Conditions shall be allowed
         unless written notice has been given as required.

                 11.9     OUTSIDE PLANT SERVICES SCHEDULING.  Prior to the
pre-construction meeting, Supplier shall submit a detailed Outside Plant
Services Scheduling schedule as set forth in the Specifications. The Engineer,
Supplier and Ordering Company Representative shall hold weekly status meetings
at mutually agreed upon times and places.  Additional coordination between the
parties will be held on an as needed basis as set forth in the Specifications.

                 11.10    INSPECTION AND CORRECTION OF DEFECTS; ACCEPTANCE.
(a) Ordering Company's Representative shall have free access to the Work
performed and materials furnished by Supplier under this Agreement for the
purpose of inspection thereof.  Prior to the commencement of the Warranty
Period (as defined in Section 11.12, WARRANTY, below), Supplier shall upon
receipt of written request from Ordering Company's Representative, furnish
sufficient labor and facilities at Supplier's expense, to make an inspection
of Work already completed by uncovering and exposing the Work for inspection.

                 (b)      If the inspection discloses that the Work reasonably
conforms to the applicable Specifications in all material respects, the cost to
Supplier of (i) uncovering and exposing the Work, and (ii) examining and
restoring of the Work shall be considered a Change Order and shall be paid for


by Ordering Company.  In addition, if completion of the Work has been delayed
thereby, Supplier shall be granted a suitable extension of time and/or delay
and disruption compensation, as mutually determined by Ordering Company and
Supplier.

                                       88




                 (c)      If the inspection discloses that the Work does not
conform to the applicable Specifications in all material respects, Supplier
shall not have a basis for a Change Order and shall correct the Work at its own
expense.  The Completion Date shall not be extended because of any delay caused
by such non-conforming Work.

                 (d)      If Ordering Company notifies Supplier of a defect or
non-conformance during the progress of the Work or prior to Final Acceptance or
Beneficial Occupancy, Supplier will schedule the repair or replacement of such
Work within two (2) work days after receipt of written notice.

                 (e)      Supplier may submit to Ordering Company a notice of
completion, placing Ordering Company on notice that the Work is complete and
ready for inspection.  Ordering Company shall inspect the Work promptly and in
no event later than seven (7) business days after receipt of such notice.  In
the event that Ordering Company does not inspect the Work within such time
period, Final Acceptance shall be deemed to have occurred with respect to such
Work.  If the inspection results in a Punch List, Final Acceptance shall occur
when the Punch List is complete to Ordering Company's reasonable satisfaction.
Again, Supplier may submit a notice of completion regarding the Punch List and
the same procedure set forth above shall apply (i.e., Ordering Company shall
inspect the Work no later than seven (7) business days after receipt of such
notice and Final Acceptance shall be deemed if Ordering Company fails to
inspect within that time).

                 11.11    SUPERVISION; CONTROL OF WORK.  (a) Supplier shall
keep on the Work site a competent Superintendent and any necessary assistants
and all of them shall be reasonably satisfactory to Ordering Company's
Representative.

                 (b)      Supplier shall have full control and direction (i)
over the mode and manner of doing the Work, subject to Sections 6.20,
COMPLIANCE WITH LAWS, and 11.18, ARCHAEOLOGICAL SITES; ENVIRONMENTAL
PROTECTION, and MOPS and (ii) of its personnel employed on or about the Work.

                 11.12    WARRANTY.

                 (a)      FOR PRODUCTS.  The Warranty  for  Products is set
         forth in Section 8.2, WARRANTY; the Warranty Period is set forth in
         Exhibit 8-1, provided, however, that the Warranty Period begins on
         the earlier of Final Acceptance of a completed Work Order or
         Beneficial Occupancy.

                 (b)      FOR SERVICES.   The warranty shall begin on the


earlier of Final Acceptance of a completed Work Order or Beneficial Occupancy
and shall extend for one (1) year (the "Warranty Period").  Supplier agrees to
perform Work in a professional manner; using competent and responsible
personnel trained as required by the most stringent of accepted industry
practice, Supplier practice, Section 6.20 COMPLIANCE WITH LAWS, and Applicable
EH&S Requirements (Section 11.18 (c)); and in accordance with the
Specifications or other

                                       89




agreed upon specifications and in accordance with accepted practices in the
community in which the Work is performed using material free from defects
except where such material is provided by Ordering Company.  If Work provided
by Supplier proves not to have been so performed, and if Ordering Company
notifies Supplier in writing to that effect within the Warranty Period, then
Supplier shall, at its option, correct any defects or render a full pro-rated
refund or credit based on the original charges for the Work.

                 (c)      If the refund or option is not chosen and if, during
the Warranty Period, Ordering Company notifies Supplier of a defect covered
under paragraphs (a) and (b) above, then Supplier shall commence to repair or
replace such Work within seven (7) days after receipt of written notice.
Notwithstanding the above, if the refund or credit option is not chosen and if
Ordering Company notifies Supplier that the defective or non-conforming Work is
of a critical nature for network protection or for safety reasons, Supplier
shall commence to repair or replace the Work within twenty-four (24) hours
after receipt of written notice.

                 (d)      The warranties provided in this Section 11.12 do not
cover repair for damages, malfunctions or service failures caused by:  (i)
actions of any personnel not employed, directly or indirectly, by  Supplier;
(ii) Ordering Company's failure to follow Supplier's installation,
maintenance or operation instructions; or (iii) a condition of Force Majeure.

                 (e)      THE WARRANTIES STATED IN THIS SECTION 11.12 ARE
EXCLUSIVE AND ARE IN LIEU OF ALL OTHER EXPRESSED OR IMPLIED
WARRANTIES,
INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY OR
FITNESS FOR A
PARTICULAR PURPOSE.  EXCEPT FOR (a) TANGIBLE PROPERTY DAMAGE AND
PERSONAL
INJURY FOR WHICH SUPPLIER IS HELD LIABLE AND (b) THE REMEDY PROVIDED
IN SECTION
5.1(e), ORDERING COMPANIES'  REMEDIES, ORDERING COMPANY'S SOLE AND
EXCLUSIVE
REMEDY SHALL BE SUPPLIER'S OBLIGATION TO REPAIR, REPLACE, MAKE
CORRECTIONS OR
REFUND AS SET FORTH ABOVE IN THIS WARRANTY.

                 (f)      PRODUCT RELOCATION OR MODIFICATION.  Ordering Company
shall advise Supplier promptly of any change in location or modification to any
Product covered by warranty service under this Agreement. If such change, in
Supplier's opinion, creates a safety hazard or is likely to cause a
malfunction, Supplier may at Ordering Company's expense, correct the


condition.  If the condition cannot be corrected to Supplier's reasonable
satisfaction, Supplier reserves the right to terminate without liability
warranty service under this Agreement for the products relocated and/or
modified.

                 11.13    SAFETY; EMERGENCY.  (a) Supplier shall be responsible
for the safety of the Work it performs; provided, however, that Supplier shall
not be responsible for any unsafe circumstance caused by Ordering Company or
Others.

                 (b)      Whenever, in the reasonable opinion of Ordering
Company or the Engineer, Supplier has not taken sufficient precautions for the
safety of the public or the

                                       90




protection of the Work or adjacent structures or property, and whenever, in the
reasonable opinion of Ordering Company or the Engineer, an emergency has arisen
and immediate action is considered necessary, then Ordering Company, with prior
notice to Supplier, may provide suitable protection by causing Work to be done
and material to be furnished and placed.  To the extent that Supplier is
responsible for such emergency, the reasonable out-of-pocket cost of such Work
and material shall be borne by Supplier, and if the same is not paid on
presentation of the bills therefor, such costs may be deducted from amounts due
or to become due Supplier.  The performance of such emergency Work shall not
relieve Supplier to the extent of its responsibility for damage which may
occur.  Ordering Company shall make a good faith effort to contact and utilize
the services of Supplier to correct the emergency protection problem prior to
retaining the services of another contractor.

                 11.14    ENGINEER'S DRAWINGS AND SPECIFICATIONS.  (a) Supplier
will be furnished a sufficient number of sets of Drawings including revisions
thereto and sufficient copies of the Specifications without charge.  All
Drawings and Specifications shall be returned to the Engineer upon completion
of the Work. Supplier may retain sufficient copies to perform its Warranty
administration.

                 (b)      The Drawings shall be signed by Ordering Company's
Representative and by Supplier.

                 (c)      Supplier shall conduct a normal and customary check
of all dimensions, elevations, and quantities indicated on the Drawings and
lists furnished by the Engineer. If Suppliers discovers in the course of its
work, major discrepancies between the Drawings and the conditions at the site,
errors or omissions in the Drawings, and in the layout as given by stakes,
points, or instructions, Supplier shall notify the Engineer.   Supplier will
not be allowed to take advantage of errors or omissions in the Drawings or
other Agreement Documents.  Full instructions will be furnished by the Engineer
should such error or omission be discovered, and Supplier shall carry out such
instructions as if originally specified; provided, however, that in the event
that such instructions result in an increase in Supplier's costs or in a
Construction Delay (as defined in Section 11.20, CONSTRUCTION DELAY, below) in
the Completion Schedule, Supplier shall be entitled to reasonable compensation
and, if necessary, an extension in the Completion Schedule.

                 11.15    REFERENCE STANDARDS.  Reference to the standards of
any technical society, organization, or association, or to codes of local or
state authorities, or AT&T EH&S Practices shall mean the latest standard, code,
Specification, or tentative standard adopted and published, unless specifically
stated otherwise.  Since the Agreement will likely cover multiple years, except


as otherwise required by Section 6.20, COMPLIANCE WITH LAW, Supplier will be
given sufficient time to assess and comply with new standards, and to request
additional time and/or compensation for compliance.

                 11.16    RECORDS. Supplier shall maintain complete records
including, but not limited to all labor and equipment hours, material
purchased, and Work subcontracted to other

                                       91




parties.   The records shall be maintained in accordance with recognized
commercial accounting practices and in such manner that they may be readily
audited.  The records, including all supporting documents, shall be available
at all reasonable times for audit by Ordering Company both during the contract
period and for one year following the date of final payment or until all
disputes, if any, between Supplier and Ordering Company have been finally
resolved, whichever is later. Supplier shall also maintain weekly sheets,
showing all labor and equipment employed and material received.

                 (a)      Supplier shall maintain at the site where Work is
being performed or Supplier's local construction office a file of current
copies of all Drawings, Specifications, and other Agreement Documents and
supplementary data.

                 (b)      Supplier shall create a timed and dated pictorial
record of the Site, including paths of ingress and egress, before and after
Work is performed for the purpose of precluding or settling claims.

                 11.17    UNFAVORABLE CONSTRUCTION CONDITIONS.  (a) During
periods of unfavorable weather, wet or frozen grounds, or other unsuitable
construction conditions, Supplier shall confine its operations to Work which
will not be affected adversely thereby.  No portion of the Work shall be
constructed under conditions which would adversely affect the quality or
efficiency thereof, unless special means or precautions are taken by Supplier
to perform the Work in a proper and satisfactory manner.

                 (b)      If adverse weather conditions are encountered by
Supplier or its subcontractor(s) which are abnormal for the location and time
of year for which such claim is made, the construction schedule shall be
extended by an amount of time equal to the effect of such adverse weather.  If
adverse weather is the basis of a claim by Supplier for additional time, such
claim shall be documented by Supplier and include data substantiating that
weather conditions were abnormal for the period of time in question and
Supplier could not have been reasonably anticipated such adverse weather and
that such weather conditions had an adverse effect on the construction
schedule.

                 11.18    ARCHAEOLOGICAL SITES; ENVIRONMENTAL PROTECTION.  (a)
Known archaeological, historical or cultural sites along the route will be
indicated on the Drawings by the Engineer.

                 (b)      If archaeological, historical or cultural artifacts
are encountered during construction anywhere along the route, construction at
that location shall stop and the Engineer shall be promptly notified. Supplier


shall not harm or disturb such artifacts until instructed by Ordering Company
or Engineer as to how to proceed.  If an extended delay is anticipated,
Supplier may elect to move to another location of Work.  Notwithstanding
anything to the contrary herein, Demobilization and Remobilization or
construction delay due to unanticipated

                                       92




archaeological findings shall be a basis for extra payment.  Ordering Company
shall be responsible for obtaining any necessary permits in order to continue
Work in the affected area.

                 (c)      Ordering Company shall provide Supplier with AT&T
EH&S Practices, including updates.  At the end of each calendar year, Ordering
Company shall provide Supplier a list of all AT&T EH&S Practices still in
effect.  AT&T EH&S Practices shall be deemed applicable to the Work under a
Work Order only when provided to Supplier at or prior to the date of the Work
Order.  Supplier shall at its own expense comply with the most stringent of:
applicable governmental laws, regulations, ordinances, rules, codes, orders,
guidances, permits, approvals; applicable easement or license conditions;
applicable Supplier EH&S practices; and applicable AT&T EH&S Practices
(collectively "Applicable EH&S Requirements").

                 (d)      Supplier shall be deemed the generator of all waste
associated with the Work and shall dispose of that waste at its own expense as
set forth in Section 11.18(c), ARCHAELOGICAL SITES; ENVIRONMENTAL PROTECTION,
above.  "Waste" shall include without limitation all hazardous and
non-hazardous substances and materials associated with the Work which are
intended to be discarded, scrapped, or recycled.  It shall be presumed that all
substances and materials associated with the Work that are not incorporated
into the Work (including without limitation damaged components or tools,
leftovers, containers, garbage, scrap, residues or byproducts), except for
substances and materials that Supplier or Ordering Company intend to use in
their original form in connection with similar work, are waste.

                 (e)      In the event conditions are discovered or created at
or near the site of the Work which may require (i) investigation or remediation
or (ii) unforeseen measures to protect the environment, health or safety
(collectively "Adverse EH&S Conditions"), the party discovering the condition
shall immediately notify the other party.  The party in the best position to do
so (or, if the parties are equally situated, Supplier) will then immediately
take reasonable measures temporarily to contain or otherwise avoid exacerbation
of or exposure to the conditions.  Unless Ordering Company affirmatively
notifies Supplier otherwise, Supplier shall also take such other actions as
Applicable EH&S Requirements prescribe.

                 (f)      In the event Supplier's failure to comply with
Section 11.18(c), ARCHAELOGICAL SITES; ENVIRONMENTAL PROTECTION,  above or
Supplier's negligence or willful misconduct was a not insignificant cause of
(i) the Adverse EH&S Conditions or (ii) exacerbation of the Adverse EH&S
Conditions, Supplier shall indemnify and hold harmless Ordering Company and be
responsible for all costs associated with curing the Adverse EH&S Conditions.


In all other events Ordering Company shall indemnify and hold harmless Supplier
from and be responsible for all costs associated with curing the Adverse EH&S
Conditions.

                 11.19    REPORTING DEFECTS.  (a) If any part of Supplier's
Work depends, for its proper execution or results, upon the Work of any Others,
excepting Subcontractors, Supplier shall inspect and promptly report to
Ordering Company's Representative any defects in the Work

                                       93




that render it unsuitable for the proper execution or results, and Supplier
shall not proceed with that phase of the Work until so authorized by Ordering
Company's Representative.  Ordering Company may request and Supplier shall
provide such reports in writing.

                 (b)     Supplier shall be made aware of the delivery status of
Ordering Company furnished materials and of the progress of construction Work
being performed under separate contracts, in each case as informed by Ordering
Company pursuant to (c) below.

                 (c)      Ordering Company will furnish information to Supplier
which may be available to it regarding the status of Ordering Company furnished
materials or construction Work being performed under separate contracts.

                 11.20    CONSTRUCTION DELAY.  (a) Supplier will complete all
Work on or before the Completion Date unless either Ordering Company agrees to
extend that Date or Supplier is entitled to an extension pursuant to this
Agreement.

                 (b)      Ordering Company will perform all of its obligations,
including provision of  labor and materials to be furnished by it in such a
manner so as not to delay the progress of the Work (such being a "Construction
Delay"), and in event of its failure to do so, thereby causing loss to Supplier
or as a result of one or more of the circumstances set forth in paragraph (c)
immediately below, Ordering Company agrees that it will compensate Supplier for
such loss and, if necessary, reschedule the Completion Date to a mutually
agreed upon date. Supplier agrees that if Supplier shall delay the progress of
the Work in breach of its obligations hereunder and such delay causes Ordering
Company to sustain a loss, then Supplier will reimburse Ordering Company for
such loss, subject to the limitation of Supplier's liability set forth in
Article 5 of this Agreement.

                 (c)     Notwithstanding anything to the contrary in this
Agreement, among the causes of "Construction Delay" for which Supplier shall be
compensated and the Completion Date shall be rescheduled pursuant to paragraph
(b) immediately above, are the following:

                         (i)      Lack of Ordering Company Permits;

                         (ii)     Lack of Ordering Company furnished material;

                         (iii)    Work stoppage by landowner;

                         (iv)     Work stoppage by permitting agency even


         though Supplier has met the requirements of the relevant permits;

                          (v)     Railroad company denying access to the
         right-of-way or rail due to railroad's operations which regulate the
         Work conditions;


                                       94





                   (vi) Work stoppage by Ordering Company to implement new
         requirements, including changes to the Completion Date or Completion
         Schedule;

                   (vii) Waiting for the presence of the Ordering Company
         Representative;

                   (viii) Defective or damaged Ordering Company furnished
         material;
                                  
                   (ix) Special Service Precautions per the Specifications; and

                   (x) Waiting for Engineer's written approval to proceed due to
         the interference of other contractors.

               (d) Delay time is payable by Ordering Company for Construction
Delay for the reasons set forth above, when Supplier is prevented from or
delayed in working on any contracted item that is available to Supplier.
Construction Delay time will begin after Supplier has been denied access to the
Work or Ordering Company has delayed the Work for an accumulated time in excess
of one (1) hour during a given normal working day.

               (e) The term "accumulated time" shall include discontinuous
amounts of time and shall be applied to an entire crew. For example, a
four-person crew that incurred a forty five (45) minute Construction Delay due
to a permit problem and then later in the same working day incurred an
additional Construction Delay for another reason, would begin Construction Delay
time for the crew after fifteen (15) minutes of the second delay. If a crew is
into Construction Delay time at the end of a Work day and is prevented from
working on any contracted item available the next Work day and the condition
that caused the Construction Delay still exists, then Construction Delay time
shall continue without the requirement that it be in excess of one hour for the
second day.

               (f) If Supplier is forced to cease all or a portion of its
operations due to lack of right-of-way, by reason of injunction against Ordering
Company or other legal obstacles, or delay in Ordering Company-furnished
material deliveries, Ordering Company may request that Supplier move to another
site or to move off the project. At Ordering Company's request, Supplier shall
move from the portion of the project upon which he was previously engaged to
another point in the project designated by Ordering Company or to an Ordering
Company location completely off the project. Supplier shall at a later date
complete the Work left behind, when requested to do so by Ordering Company, and
such Work shall be done at prices specified in the Proposal plus Demobilization


and Remobilization.

               11.21 NOTICE OF LABOR DISPUTES. Whenever Supplier has knowledge
that any labor dispute is delaying or threatens to delay the timely performance
of the Work, Supplier shall promptly give notice thereof to Ordering Company.
Supplier shall confirm the notice in writing within three (3) Work days.

               11.22 PERFORMANCE AND PAYMENT BOND. Ordering Company shall have
the right to require Supplier to furnish a bond for the full and faithful
performance of the Work and 

                                       95




for the payment of all bills, debts and obligations related to the Work. The
bond shall be in such form, principal amount and with such sureties as may be
required by Ordering Company. Ordering Company shall reimburse Supplier for the
net premium on the bond upon receipt of the sureties' bills to Supplier.
Supplier agrees and represents that no amount for bond premium is included in
the contract price.

               11.23 APPLICATION FOR PAYMENT; TERMS OF PAYMENT. (a) Supplier
shall render to Ordering Company Applications for Payment for an amount based
upon the quantities of Work in a Work Order which have been completed by
Supplier during the monthly invoicing period, unless billing is rendered sooner
pursuant to a written modification of this Section or for delay and disruption
compensation or Special Conditions accrued as provided for elsewhere in the
Agreement. Ordering Company shall promptly approve the Application for Payment
within ten (10) business days or notify Supplier of any disputed items in an
Application for Payment. If at the expiration of such ten business day period,
Supplier does not receive written approval or rejection from Ordering Company,
the Application for Payment shall be deemed approved.

               (b) The method of measurement, basis of payment and conditions
under which payments for Special Conditions are made can be found in the
Specifications.

               (c) For material furnished by Supplier, the same terms of payment
shall apply as the terms which apply for Services billed by Supplier. For
Material supplied by Ordering Company and ordered from Supplier pursuant to
another Article of this General Purchase Agreement (e.g., an Order for cable),
the terms of payment are set forth in such Article or elsewhere in this
Agreement.

               11.24 LIENS. If as a result of any act or omission of Supplier,
any lien is filed by a Subcontractor against Ordering Company, Supplier shall
cause the same to be discharged of record within forty-five (45) days after
receipt of written notice thereof from Ordering Company.

                                   ARTICLE XII
