    be providing the Products and/or Services being ordered in the country in which the Products
    and/or Services are to be placed and/or performed, as appropriate;

    (iv)     the applicable prices, charges and fees with respect to such Products and Services;

    (v)      the location or facility to which the Products are to be delivered;

    (vi)     the incorporation by reference of this Agreement;

    (vii)    the location at which the Product is to be installed, if known;

    (viii)   the requested Ship Date and Turnover Date of the System; and

    (ix)     any other information required under this Agreement to be included in an Order.

           3.2     All purchases pursuant to this Agreement shall be made by means of Orders issued from time
  to time by Company and accepted by Nortel in writing within fifteen (15) days after receipt of the Order.  An
  Order submitted by a Company Affiliate pursuant to the terms and conditions of this Agreement, and which
  Nortel has accepted, shall constitute a Contract between the Company Affiliate ordering and Nortel or the
  applicable Nortel Affiliate.  In the event that Nortel fails to provide its acceptance of an Order in writing
  within such fifteen (15) day period, such Order shall be deemed to be accepted, provided that no additional
  or special terms and conditions have been written on the face of or otherwise incorporated into such Order. 
  Nortel shall have the right to reject any Order, or the applicable portion of such Order, placed hereunder
  from Company or a Company Affiliate, even if such Order is in accordance with the provisions of this Article
  3.

           3.3     Nortel's Director, Commercial Marketing, or such other person as designated by Nortel, shall
  forward the Order to the applicable Nortel Affiliate for fulfillment.

           3.4     All Orders issued by Company pursuant to this Agreement shall refer to and specifically
  incorporate this Agreement by reference and the terms and conditions herein shall govern the transaction
  resulting from such Order; provided that such Order is accepted by Nortel.  Preprinted terms and conditions
  set forth in Orders issued by Company, or in any prior Quotations, acknowledgments or other related
  documentation issued by any party, shall be considered null and void and shall have no force or effect;
  provided, however, that any special terms and conditions written on the face of an Order or otherwise
  incorporated into such Order shall, upon acceptance in writing by Nortel, and for such Order only, supersede
  the specific terms and conditions contained in this Agreement, including all Exhibits attached hereto, which
  are in conflict.

           3.5     Company may at any time request additions, alterations, deductions or deviations to an
  Order, subject to the condition that such changes and any adjustments resulting from such changes, including,
  but not limited to, schedules and prices, shall be mutually agreed upon and, if so agreed, subsequently
  detailed in a written revision to the applicable Order  ("Change Order").  Company acknowledges that a
  premium charge may be applied by Nortel should Nortel agree to process a Change Order outside of its standard
  Order processing cycle for a Product or in the event that a Change Order requires an additional amount of
  work (such as engineering) to be undertaken to comply with such changes.

           3.6     If Company desires to receive a budgetary or firm Quotation from Nortel for a Product or
  Service, Company shall submit such request in writing to Nortel's Director, Global Accounts, or such other
  person as designated by Nortel.  The request for Quotation shall include the information listed in Section
  3.1, as applicable.
   
           3.7     Nortel shall respond in writing to requests for budgetary Quotations and requests for firm
  Quotations.  Unless otherwise specified in the firm Quotation, such firm Quotation shall be valid for ninety
  (90) days from the date of such Quotation.  Budgetary Quotations shall be provided for information and
  planning purposes only and shall not be considered to be a final or firm statement binding on either party. 
  All prices will be quoted in U.S. dollars, unless otherwise agreed.  The Quotations shall include the
  following information:

    (i)      Budgetary Quotations
             (a)     preliminary Hardware and Software lists;
             (b)     the estimated charges for the Products;
             (c)     the estimated charges for Services requested; and
             (d)     any other information requested by Company.

    (ii)     Firm Quotations
             (a)     the price to be paid by Company for the Products, after applying the
      applicable discounts, if any;
             (b)     fixed charges for Services requested;
             (c)     complete Hardware and Software lists and project schedules; and
             (d)     any other information requested by Company.

           3.8     The Ship Date shall be based on Nortel's standard intervals for the applicable Product;
  however, the parties shall always mutually agree on the Ship Date and take into consideration any unique
  aspect of the applicable project.

           3.9     Orders may be issued either electronically, such as through electronic data interchange, or
  via traditional manual methods, as mutually agreed to by the parties.

           3.10    Company absolutely, irrevocably and unconditionally guarantees the performance of every
  Company Affiliate issuing Orders and/or otherwise acting under this Agreement and any Contract created
  thereby.  Company hereby expressly waives any other diligence, protest or notice as well as any requirement
  that Nortel exhaust any remedy or right against  such Company Affiliate.

             ARTICLE 4.  PRICE AND PAYMENT

  4.1Nortel shall charge Company for each Product and/or Service ordered by Company in accordance with the
  prices set forth in each accepted Order, which prices shall be based upon prices identified in one of (i) a
  Product Annex, (ii) a Firm Quotation, (iii) Nortel's then current prices, or (iv) as specified elsewhere in
  this Agreement or as otherwise mutually agreed in writing.  

           4.2     All Products shall be priced and delivered in accordance with Ex Works, Nortel's applicable
  facility.

           4.3     Nortel's prices, if set forth in Exhibit A, may be revised by Nortel no more than once each
  calendar year, by providing sixty (60) days prior written notice to Company.  Such notice shall specify the
  effective date of the price change and shall apply to all Orders received by Nortel on or after the effective
  date of the price change. However, in the event that there is a recognized industry-wide shortage of a
  component that is incorporated in a Product, Nortel may increase the price of such Product, following the
  provision of written notice to Company fifteen (15) days prior to the effective date of such increase or such
  shorter date as is mutually agreed in view of the shortage.  The price increase of such Product due to a
  component shortage shall be limited to a reasonable amount under the then-current circumstances having regard
  for industry conditions for the period of time during which such recognized shortage exists.  Following the
  implementation of a price increase due to a component shortage, the parties shall jointly review every three
  (3) months or at such other time as is mutually agreed, in good faith, whether such component shortage still
  exists.  If the component shortage has abated, the parties shall jointly determine whether there still is a
  need for such price increase. In addition, in the event that  worldwide hyperinflation occurs, the parties
  shall work together in good faith to determine any applicable increase in prices of affected Products to
  cover Nortel's additional costs.

           4.4     For all Orders, Nortel shall invoice Company for Products and Services as follows, unless
  otherwise agreed to in writing:

    (i)      for Systems, whether or not installation has been ordered from Nortel, one hundred
    percent (100%) of the price of the Products on the Ship Date, one hundred percent (100%) of
    the price of any Services upon the date of completion of such Services, except with respect
    to installation Services, if any,  which shall be invoiced one hundred percent (100%) upon
    Turnover;

    (ii)     for Merchandise or Documentation provided on a furnish-only basis, one hundred
    percent (100%) of the price on the Ship Date; and

    (iii)    for Orders covering Services only,  one hundred percent (100%) of the price for such
    Services following completion of performance, except for recurring support Services which
    shall be billed quarterly in advance unless otherwise agreed.  Some Services may be subject
    to monthly invoicing as set out in a Product Annex or separate Service agreement.  To the
    extent such Services are to be invoiced differently than set out in this paragraph (iii),
    such differences shall be set forth in the applicable Product Annex or separate Service
    agreement and such provisions shall take precedence.

           4.5     Each invoice shall be paid in full within thirty (30) days after the date of such invoice. 
  In the event that Company does not pay an invoice in full within such thirty (30) day period, then Nortel may
  charge Company interest on the outstanding portion of such invoice from day thirty one (31) forward, at the
  rate of one and one half percent (1.5%) simple compound interest per month, or such lesser amount as may be
  the maximum permissible rate under applicable law, until such time as the outstanding invoice is paid.  In
  addition, Company agrees to pay all collection costs and reasonable legal fees incurred by Nortel as a result
  of late payment or non-payment by Company.

                    ARTICLE 5.SHIPMENT, TITLE AND RISK OF LOSS

           5.1     Prior  to the  Ship  Date, Company  shall have  the right  to  reschedule any  pending Orders;
  provided  that (i)  a minimum  period of  notice prior  to such  Ship Date  is given  to  Nortel by  Company in
  accordance with the  applicable Product Annex; and  (ii) the new  Ship Date is within  ninety (90) days of  the
  original Ship  Date.  However, each Order may only be rescheduled once.  Company shall reimburse Nortel for any
  storage fees, insurance and demurrage costs incurred with respect to such rescheduled Orders.

           5.2     All Products  shall be delivered to Company in  accordance with Ex Works  and risk of loss and
  damage  to Products shall be  construed as defined  therein.    Company shall keep  such Products fully insured
  for the total  amount then due Nortel  for such Products. Company shall pay transportation  charges, including
  insurance, associated  with the  shipment of  Products; provided  however, that  if the  parties agree,  Nortel
  shall prepay transportation charges, and insurance  for delivery of Products to  the Installation Site or other
  delivery location or  other designated receiving point  as specified in an Order.   The charges therefor  shall
  be invoiced by Nortel and paid by Company to Nortel in accordance with Article 4 above.

           5.3     Good title  to Hardware  furnished hereunder, free  and clear of  all liens  and encumbrances,
  shall vest in Company upon full payment to Nortel of the total amount payable  by Company for such Hardware and
  any related Licensed Software or Services ("Total Fee")  furnished by Nortel in connection with such  Hardware.
  Prior to payment of the Total Fee  for the Products and Services in an  Order, Company shall not sell or  lease
  the Hardware,  or allow  any liens  or encumbrances  to attach  to the  Hardware or   Software,  or remove  the
  Hardware or Software from the  Installation Site without the prior written consent of  Nortel, such consent not
  to be unreasonably withheld.

           5.4     If Company notifies  Nortel prior to a  Ship Date that Company  does not wish to  receive such
  Products on the Ship Date, or  the Installation Site or other  delivery location is not prepared in  sufficient
  time  for Nortel  to make delivery  in accordance  with such  date, or  Company fails  to take delivery  of any
  portion of the Products in an Order when shipped, Nortel may place the applicable Products in storage. In  that
  event, Company  shall be liable for all additional costs thereby incurred by Nortel.  Delivery by Nortel of any
  Products  to a storage location  as provided above  shall be deemed  to constitute delivery of  the Products to
  Company for  purposes of  this Agreement,  including, without  limitation, provisions  for payment,  invoicing,
  passage of risk of loss, and commencement of the warranty period.

           5.5     Until the Total  Fee is  paid, Company grants  to Nortel  and/or its agents  a purchase  money
  security interest in  the Products in an  Order and their proceeds  or such other similar protection  as may be
  available in the applicable  jurisdiction.  Company  shall cooperate with Nortel  in preserving and  perfecting
  Nortel's  security interest in the Products  and Company shall promptly (i)  execute and deliver to Nortel such
  financing  statements as  Nortel may  require and  (ii) execute  and deliver  to Nortel  such other agreements,
  documents  and instruments  as  Nortel may  require to  perfect and  maintain  the validity,  effectiveness and
  priority of the security interest created or intended to be created by this Agreement. 

           Company  authorizes Nortel  to file one or  more financing  or continuation  statements and amendments
  thereto, relating  to all  or any  part of  the Products  in an Order  without signature  of the  Company where
  permitted by law. A carbon, photographic or other reproduction  of this Agreement or of any financing statement
  covering the Products or any  part thereof shall be sufficient as  a financing statement and may be filed  as a
  financing statement. 

           Company shall not  sell, lease or otherwise transfer  the Products or any  portion thereof, except  to
  Company Affiliates only, or allow any  liens or encumbrances to attach to such Products or  any portion thereof
  prior to payment  in full of the Total Fee. Company Affiliates shall not  sell, lease or otherwise transfer the
  Products or any portion  thereof or allow any liens or  encumbrances to attach to such Products  or any portion
  thereof prior to payment in full of the Total Fee.

           5.6.1   Company shall provide  Nortel or its subcontractors  with access to its Installation  Sites or
  other Company facilities  during the times specified  by Nortel and as  are reasonably necessary for  Nortel to
  perform its obligations hereunder. Nortel  shall comply with Company's reasonable site and security regulations
  of which Nortel is informed by Company.  

           5.6.2   All sites at which the  Products shall be delivered or installed shall be  prepared by Company
  in accordance  with Nortel's standards,  including, without limitation,  environmental requirements.   Prior to
  and during installation,  Company shall ensure the timely  and adequate delivery, installation  and functioning
  of the  electrical and  communications  connections and  other environmental  requirements, including  but  not
  limited to,  HVAC systems, specified in  Nortel's instructions, Specifications,  Documentation  or in a Product
  Annex.

           5.6.3   Company shall  provide  reasonable  working  space  and  facilities,  including  heat,  light,
  ventilation, telephones,  electrical current, waste  removal and other necessary  utilities, for use  by Nortel
  personnel performing installation or other Services, and adequate  secure storage space, if required by Nortel,
  for Products and materials.   Company shall also provide adequate security against theft,  damage or other loss
  for the Products while on Company's Installation Site or other delivery location specified by Company.

           5.6.4   Company shall obtain  all necessary governmental  permits applicable to Company  in connection
  with the installation,  operation, and maintenance  of Products furnished  hereunder, excluding any  applicable
  permits required  in the normal  course of Nortel's  doing business.   Any information which  Nortel reasonably
  requests from Company and which is necessary for Nortel  to properly install or maintain the Products shall  be
  provided by Company to Nortel in a timely fashion and in a form reasonably specified by Nortel.

     ARTICLE 6.  TESTING, TURNOVER AND ACCEPTANCE

  6.1If installation Services are ordered by Company, Nortel shall, upon completion of such installation, test
  the Product in accordance with Nortel's Turnover procedures to verify that such Products function
  substantially in accordance with the applicable Specifications.  Upon completion of such verification, Nortel
  shall provide to Company a written notice of Turnover.  Company shall be permitted an opportunity to have an
  appropriately qualified individual in attendance to observe the performance of such tests, however, the
  absence of such Company individual for any reason shall not invalidate the tests nor be a reason for Company
  to withhold Acceptance.

           6.2     Within ten (10) business days after the Turnover Date, Company shall either accept the
  Product in writing by execution of a notice of Acceptance, or notify Nortel in writing, specifying in
  reasonable detail those particulars in which, in Company's opinion, the Product is not in material
  conformance with the Specifications.  If Acceptance does not occur within such ten (10) days after the
  Turnover Date and Company has not indicated to Nortel in writing its basis for not accepting such Product,
  then Acceptance shall be deemed to have occurred.

           6.3     If Nortel does not install Products furnished hereunder, Nortel shall, prior to delivery of
  the Products, perform such factory tests as Nortel determines to be appropriate in order to confirm that such
  Products perform substantially in accordance with the applicable Specifications.  Company shall be deemed to
  have accepted the Products based upon such tests and Acceptance shall be deemed to have occurred upon the
  Ship Date. In the event that Company or any other entity intends to perform installation of Products, (except
  for installation of Products which are not permitted to be installed other than by Nortel, as specified in
  the applicable Product Annex or Documentation) Company or such entity may be required to complete
  prerequisite training or certification prior to Company being allowed to install such Product.

           6.4     In the event that Company is utilizing any Product in a revenue-generating  capacity,
  Acceptance shall be deemed to have occurred without limitation or restriction, upon the date of placement of
  such Product  into revenue-generating service.

           6.5     Products, such as Merchandise, which are purchased separately from a System, shall be deemed
  accepted upon the Ship Date.  Services which are purchased separately from a Product shall be deemed to be
  accepted upon completion of such Services or upon specific milestones as may be identified in a Product
  Annex.

           6.6     Company shall not unreasonably withhold Acceptance.  Nortel shall correct any deficiencies
  identified by Company in the manner described in this Article whereby such Products do not materially conform
  to the Specifications.  When Nortel has corrected such deficiencies, Company shall accept the Products in
  writing.  Company's failure to either accept or provide notice of non-conformance within the timeframe from
  the Turnover Date, as prescribed in Section 6.2, shall constitute Acceptance of the Products.

           6.7     Following Acceptance of Products, Company shall execute Nortel's Acceptance notice,
  confirming Acceptance without any conditions, restrictions, or limitations of any nature whatsoever.

           6.8     Acceptance shall not be withheld or postponed due to:

    (i)      Deficiencies of such Products resulting from causes not attributable to Nortel, such
    as, but not limited to (a) material change or inaccuracy of Customer Information, (b)
    inadequacy or deficiencies of any materials, information, facilities or services provided
    directly or indirectly by Company and tested in conjunction with the applicable Products, or
    spurious outputs from adjacent material, or (c) other conditions external to the Products
    which are beyond the limits specified by Nortel in the Specifications for the Products; or

    (ii)     Minor deficiencies or shortages with respect to such Products which are attributable
    to Nortel, but of a nature that do not prevent operation of the Products in revenue
    generating service.

           6.9     With respect to any deficiencies of the type described in Section 6.8(i), Nortel shall at
  Company's request and expense assist Company in the elimination or minimization of any such deficiencies. 
  With respect to any deficiencies or shortages as described in Section 6.8(ii), Nortel shall, at Nortel's
  expense, correct any such deficiencies or shortages within thirty (30) days of the date of Acceptance or as
  otherwise agreed by the parties.

           6.10    In the event that Company notifies Nortel of non-acceptance of a Product and Nortel
  personnel travel to the Installation Site to remedy such non-acceptance and determine that non-acceptance is
  due to a deficiency of the type described in Section 6.8(i), Nortel will invoice Company for Nortel's
  investigation of the matter, consisting of the standard labor rate for Nortel's personnel who travel to the
  Installation Site and the reasonable travel and living expenses incurred by such personnel. 

            ARTICLE 7.  ORDER CANCELLATION

  7.1If, prior to the Ship Date, Company cancels all or any part of an Order, Company shall pay to Nortel a
  cancellation charge for the Products or each item of Third Party Hardware or Third Party Software that has
  been canceled in accordance with the schedule set forth in the applicable Product Annex. 

  7.2Orders for Products that have been shipped may not be canceled.  Furthermore, Orders for Products which
  Nortel customizes in accordance with a specific Company request may not be canceled.

                            ARTICLE 8.  WARRANTY

            8.1  Nortel warrants that for a period of twelve (12) months from the Ship Date of a System, the Hardware
  contained in such System under normal use and service will be free from defective material and faulty
  workmanship and shall comply with the applicable Specifications. The warranty period for Merchandise shall be
  ninety (90) days from the Ship Date of such Merchandise.  The foregoing warranties shall not apply to items
  normally consumed during operation of a System such as, but not limited to, lamps and fuses.  

            8.2  Nortel warrants that any installation Services performed by Nortel with respect to a System will be free
  from defects in workmanship for a period of twelve (12) months from the completion date of such Services. 

            8.3  Nortel warrants that any Licensed Software shall function during the warranty period of the Hardware with
  respect to which such Licensed Software is furnished without any material, service-affecting, non-conformance
  to the applicable Specifications.  Licensed Software that is delivered separately from Hardware is warranted
  for a period of twelve (12) months from the applicable Ship Date.  If the Licensed Software fails to so
  function, Company's exclusive remedy and Nortel's sole obligation under this warranty is for Nortel to
  correct such failure through, at Nortel's option, the replacement or modification of the Licensed Software or
  such other actions as Nortel reasonably determines to be appropriate, all within a reasonable time having
  regard to all of the circumstances and failing which the parties agree to negotiate a commercially reasonable
  solution.  Any modification to the Software not performed by Nortel, other than with respect to Modifiable
  Software, shall void this warranty. 

           8.4     If Hardware is not free from  defects in material or workmanship and fails to comply with  the
  applicable  Specifications during  the warranty  period,  Nortel  will repair,  replace or  modify at  its sole
  option the  defective Hardware  so that  it substantially  complies with  the applicable  Specifications.   The
  warranty service shall be performed at the Installation  Site or Nortel's facility as determined  by Nortel. If
  Nortel is unable to repair  or modify the defective Hardware  within a reasonable period of  time so that such
  Hardware  conforms to the applicable Specifications, Nortel shall replace  the defective Hardware with Hardware
  that conforms  to such Specifications.  Replacement Hardware may  be new or reconditioned  at Nortel's option.
  Nortel's sole  obligation and  Company's exclusive remedy  under the warranty  provisions of this  Article with
  respect to Hardware and installation  Services shall be limited to repair,  modification or replacement of the
  defective Hardware or correction of the defective installation Services.

           8.5     Notwithstanding the  foregoing, the warranty period  of Hardware  which has  been subject  to
  repair or replacement by Nortel shall  commence upon the Ship Date of the repaired or replacement  Hardware to
  Company and  shall expire on the  later of ninety  (90) days or the  last day of  the original warranty period
  with respect to the Hardware which was repaired  or replaced.  The warranty period of  Licensed Software which
  has been corrected,  due to  a material, service-affecting non-conformance  found in  such Licensed  Software,
  shall expire  on the  later of  ninety (90) days from  the Ship  Date of  the corrected  Licensed Software  to
  Company or the last day of the original warranty period with respect to such Licensed Software.

           8.6     Nortel warrants that  its Products shall comply  in all material aspects  with all applicable
  laws and regulations  in force in the country  of destination known to Nortel, which are in  force on the date
  of acceptance  of the  applicable Order therefor,  which laws or  regulations directly impose  obligations upon
  any manufacturer,  Nortel or, if  applicable, installer of  such Products.  Upon request  therefor, Nortel may
  implement such changes  as are necessary  to comply  with any applicable  law and/or regulation  which becomes
  effective after the date of acceptance  of the applicable Order; provided that the parties have reached  mutual
  agreement concerning the cost of such changes and which party will bear them.

           8.7     The performance by  Nortel of any of its  obligations described in this  Article 8 shall  not
  extend the applicable warranty period. 

           8.8     The warranties set forth in this Article shall  not apply to any Products where  the defect or
  non-conformance is  due  to  (i)  accident,  fire,  explosion,  power  failure,  power  surge  or  other  power
  irregularity, lightning, alteration, abuse,  misuse or repair not performed by Nortel; (ii)  improper storage;
  (iii)  failure to  comply  with  all applicable  environmental requirements  for the  Products as  specified by
  Nortel  or any other  applicable supplier,  such as  but not  limited to  temperature or humidity  ranges; (iv)
  improper performance of  installation, maintenance, operation or other service in connection  with the Product,
  provided that such  service was not performed by Nortel or on Nortel's behalf; (v)  use in conjunction with an
  incompatible product  or a  product not purchased  under this  Agreement; (vi) any  error, act  or omission  by
  anyone other than Nortel; or (vii) where written notice of the defect  has not been given to Nortel within  the
  applicable warranty period. The  warranties set forth in this Article  shall not apply to Third Party  Software
  or  Third Party Hardware,  provided however  that Nortel  shall assign  to Company  (to the extent  of Nortel's
  right to do  so) the warranty rights granted to Nortel by the appropriate vendor  of such Third Party Software
  or Third Party Hardware.

           8.9     Unless  Nortel elects  to  repair  or replace  defective Hardware  at Company's  facility, all
  Hardware to  be repaired  or replaced,  whether in  or out of  warranty, shall  be de-installed  and packed by
  Company in  accordance with Nortel's  instructions.  Nortel  shall use reasonable efforts to  ship repaired or
  replacement Hardware  within thirty  (30)  days of  receipt of  the  defective Hardware.    To facilitate  the
  processing of the defective  Hardware returned hereunder, Nortel may  ship replacement Hardware prior to Nortel
  receiving the  defective Hardware.  In  the event that  Company fails to return  defective Hardware and  Nortel
  has  shipped such  replacement Hardware,  Nortel shall  invoice Company  at  Nortel's applicable  then-current
  prices for such  replacement Hardware, thirty (30) days after the Ship Date of  such replacement Hardware.  If
  mutually agreed, Nortel will make repairs on-site at Nortel's then-current charge for such repairs. 

           8.10    If  the Hardware returned  to Nortel pursuant to  Section 8.9 is  determined by  Nortel to be
  beyond repair and  is outside the warranty  period, Nortel shall notify Company  and if requested Nortel  shall
  sell Company replacement Hardware at Nortel's then-current prices for such replacement Hardware. 

           8.11    Company shall bear  risk of loss or  damage and shall pay for all transportation  charges for
  Hardware returned  to Nortel and Nortel shall  bear risk of loss or damage and  pay for transportation charges
  for repaired or  replacement Hardware shipped  to Company.   Title  to repaired Hardware  shall pass to  Nortel
  upon receipt.  Title to replacement Hardware shall pass to Company upon receipt. 

           8.12    Nortel  and  Nortel's  vendors   of  Third  Party  Hardware  and  Third  Party  Software,   as
  appropriate,  shall  not have  any  responsibility to  Customers  for warranties  offered  by  Company  to such
  Customers and  Company hereby indemnifies and holds  harmless Nortel and Nortel's vendors, as appropriate, from
  any claims, damages or  liabilities arising out of, or relating to,  any warranties offered by Company to such
  Customers.

           8.13    THE  WARRANTIES,  CONDITIONS AND  REMEDIES SET  FORTH HEREIN  CONSTITUTE THE  ONLY WARRANTIES,
  OBLIGATIONS  OR CONDITIONS OF  NORTEL WITH  RESPECT TO  THE PRODUCTS  AND SERVICES  AND ARE COMPANY'S  SOLE AND
  EXCLUSIVE  REMEDIES IN THE EVENT  THAT SUCH WARRANTIES OR  CONDITIONS ARE BREACHED.   THEY  ARE  IN LIEU OF ALL
  OTHER WARRANTIES  OR CONDITIONS,  WRITTEN OR ORAL,  STATUTORY, EXPRESS OR  IMPLIED, INCLUDING, BUT  NOT LIMITED
  TO, THE IMPLIED WARRANTY OF MERCHANTABILITY  AND FITNESS FOR A PARTICULAR PURPOSE.   NORTEL SHALL NOT BE LIABLE
  FOR  ANY INDIRECT, INCIDENTAL, SPECIAL, PUNITIVE  OR CONSEQUENTIAL DAMAGES, INCLUDING  WITHOUT LIMITATION LOST
  REVENUES  OR PROFITS  OR OTHER  ECONOMIC LOSS,  OF ANY  NATURE WHATSOEVER  ARISING OUT  OF NORTEL'S  BREACH  OF
  WARRANTY OR CONDITION.

                            ARTICLE 9.  NORTEL'S ADDITIONAL OBLIGATIONS

           9.1  Nortel shall make training available to representatives of Company with respect to the operation,
  configuration, installation, service, maintenance and support of the Products at Nortel's then current prices
  and at Nortel's facilities, subject to course and class availability.  The training provided under this
  Section 9.1 may be provided within the U.S. or at an offshore location, at Nortel's discretion.  Nortel shall
  provide Company with a certain number of student training days ("Training Credits"), as set forth in the
  Product Annexes, to be used by Company in any of Nortel's training courses related to the Products that
  Company has purchased.  The Training Credits for each Product may only be used in connection with such
  Product and must be used within one (1) year from the date such Training Credits were earned, after which
  such Training Credits will be forfeited by Company.

           9.2     Upon request, Nortel shall provide Company with copies of its then current training
  catalogue. Company shall provide Nortel with a reasonable number of names and addresses of people to whom
  this catalogue should be sent.  Upon the request of Company, Nortel shall provide to Company such additional
  training as Company requests, at a time and place mutually agreed upon and at the prices to be quoted for
  such training. The cancellation fees set forth in the training catalogues shall apply.

           9.3     Nortel shall include its standard Documentation package, if any, with each shipment of
  Products.  Nortel shall make the Documentation available on its choice of media, which may include CD-ROM or
  other electronic media.  Nortel shall provide Company with any other Documentation that is ordered at its
  then-current prices therefor.  Documentation provided via Nortel's CD-ROM media may be printed and copied and
  Documentation provided in paper format may be copied, to the extent such Documentation so provides, and only
  to the extent such printing or copying is necessary for the operation and maintenance of the Products to
  which the Documentation pertains.  However, Company may not press any copies of CD-ROM discs.

           9.4     During the term  of this Agreement, Company  may acquire various support Services  from Nortel
  in  connection  with the  Products  that Company  acquires  from Nortel  under this  Agreement.  These Services
  include, but are not limited to the  following: technical assistance Services, installation Services,  Hardware
  maintenance  Services, software  maintenance  Services and  parts  repair and  replacement  Services.   Certain
  support  Services that Company may are described in Exhibit B, the Master Services Agreement, which is attached
  hereto and incorporated  herein. The  fees for such  support Services,  if ascertained upon  execution of  this
  Agreement are  set forth in  Exhibit B.  Fees for  any support Services  not described  in Exhibit  B shall  be
  provided on an as-quoted basis pursuant to Nortel's applicable terms and conditions.

                                 ARTICLE 10.  SOFTWARE LICENSE 

       10.1       Company acknowledges that the Software may contain programs which have been supplied by, and are
  proprietary to, Third Party Software vendors. In addition to the terms and conditions herein, Company shall
  abide by any additional terms and conditions specified in a Product Annex with respect to any Software
  provided by any Third Party Software vendor.

       10.2        Upon Company's payment to Nortel of the applicable fees with respect to any Software
  furnished to Company pursuant to this Agreement, Nortel hereby grants to Company, subject to the applicable
  terms and conditions of this Article 10, a personal, non-exclusive, right and license to use the Object Code
  version of the Software furnished to Company only in conjunction with Company's use of the Hardware with
  respect to which such Software was furnished for the life of that Hardware as it may be repaired or modified.
  Company shall be granted no title or ownership rights to the Software, which rights shall remain in Nortel or
  its suppliers.

       10.3        As a condition precedent to this license and to the supply of Software by Nortel pursuant to
  this Agreement, Nortel requires Company to give proper assurances to Nortel for the protection of the
  Software.  Accordingly, all Software supplied by Nortel under or in implementation of this Agreement shall be
  treated by Company as the exclusive property, and as proprietary and a trade secret, of Nortel and/or its
  suppliers, as appropriate, and Company shall: a) hold the Software, including, without limitation, any
  methods or concepts utilized therein in confidence for the benefit of Nortel and/or its suppliers, as
  appropriate; b) not provide or make the Software available to any person except to its employees on a 'need
  to know' basis; c) not reproduce, copy, or modify the Software in whole or in part except as authorized by
  Nortel; d) not attempt to decompile, reverse engineer, disassemble, reverse translate, or in any other manner
  decode the Software; e) issue adequate instructions to all persons, and take all actions reasonably necessary
  to satisfy Company's obligations under this license; and f) forthwith return to Nortel, or with Nortel's
  consent destroy i) upon termination of the license for any reason or ii) upon receipt of replacement,
  modified, or updated Software, any magnetic tape, disc, semiconductor device or other memory device or system
  memory and/or Documentation or other material, including, but not limited to all printed material furnished
  by Nortel to Company.

           10.4    The obligations of Company hereunder shall not extend to any information or data relating to
  the Software which is now available to the general public or becomes available by reason of acts or failures
  to act not attributable to Company.

           10.5    Nortel may  issue updates to the Software from time  to time, and, upon  Company's payment of
  applicable right  to use  fees, if any,  shall license such  updates to  Company.  Nortel  shall classify  such
  updates  as either: (i) incremental Software upgrades  ("ISUs"), designed to correct any  nonconformance to the
  applicable  Software   specifications;  or  (ii)  enhancements  which  will  provide   additional  features  or
  functionality ("Enhancements").

           Updates classified as  ISUs by  Nortel will  be provided at  no cost  to Company  during the  warranty
  period for such  Licensed Software.   The right to use fees for ISUs and Enhancements  do not include the price
  of any associated  hardware that may be required  to use such  ISUs and Enhancements.   Updates classified  as
  Enhancements by Nortel  will be made available to Company  at Nortel's applicable right  to use fees.   In the
  event  that Nortel determines that  an update includes  both ISUs  and Enhancements, such update  shall be made
  available to  Company.  If  Company elects to  receive the update, Nortel shall  invoice Company only  for the
  right to use fees applicable to the Enhancements contained in such update.

       10.6        Neither Company  nor any successor to  Company's title in the  applicable Hardware shall have
  the right  to (i) assign  this license as to  the applicable Software  to any other  person who acquires legal
  title to such Hardware, or (ii)  sublicense the rights herein granted as to  such Software to any other person
  who subsequently  acquires the  right to  use such  Hardware, unless agreed  to in writing  by both  Nortel and
  Company.  Such consent shall not be unreasonably withheld.

       10.7        Company shall indemnify and  hold Nortel and its suppliers,  as appropriate, harmless from any
  loss or damage resulting from  a breach of this Article 10.   The obligations of Company  under this Article 10
  shall survive the termination of the Agreement and shall continue if the Software is removed from service.

  Non-Licensed Software

           10.8    Certain  Software  delivered  by  Nortel  may include  Non-Licensed  Software.   Non-Licensed
  Software includes  (i) any Software for  which the applicable  right-to-use fees have not  been paid, and  (ii)
  Software for which a  periodic right to use  fee has expired  and the  applicable additional periodic right  to
  use fees  have not been  paid.  Company  shall submit to Nortel  an Order for  any Non-Licensed  Software that
  Company desires to license or renew.

           10.9    When Non-Licensed Software is placed into  service, the applicable right to  use fees shall be
  payable.   Company shall also  have the option to  pay the applicable  right to use  fees for any Non-Licensed
  Software upon installation of a Software load containing such Non-Licensed Software.

           10.10   To ensure Company's proper  activation and/or usage of only the appropriate Software,  Company
  shall complete the appropriate  form designated by Nortel, prior to  the activation and/or usage by Company  of
  any  Non-Licensed  Software.    Company shall  identify  all  Software  desired  to be  activated  and/or  used
  (including the  number of lines  or other units  activated, if applicable)  in each System  and shall  transmit
  such form to Nortel.

           10.11   Nortel shall promptly  review any  form submitted pursuant to  Section 10.10  and respond  in
  writing, identifying  whether (i)  any applicable  prerequisite Hardware  or Software  is required  by Company
  prior to  activation  and/or usage  of the  applicable  Software,  or (ii)  whether the  use  of such  Software
  requires Nortel to determine  whether the current system configuration will require additional  elements, such
  as Hardware, other hardware and/or  System memory, prior to activation and/or  usage; or (iii) whether Company
  can use such Software without the addition of any additional Hardware or Software.

           10.12   Nortel  reserves the  right  to access  by  remote polling  any  site in  which  Software  was
  installed to  determine  which Software  has been  activated.    Such polling  shall  be  done so  as  not  to
  unreasonably interfere with Company's use of the Products.

           10.13   Nortel shall  issue invoices  to Company, in  addition to those  amounts previously  invoiced,
  for amounts found  to be payable as a result of Company's activation and/or usage of any Software which Nortel
  determines as  a result  of the  remote polling of  a site and  for which Company  has not previously  paid the
  appropriate right to use fee.

           10.14   The warranty period for Software activated later than  the original Ship Date of  the Software
  load  shall be for the same period as such  original Software load and shall not be extended to provide for an
  additional period of warranty based upon  the date individual features or units are activated and/or  utilized
  by Company or the date Company pays any applicable right to use fees.

           10.15   Nortel shall  provide the Software support  Services specified in Article  9 or in a  Services
  agreement, provided that Company  maintains the Software  at Nortel's current Software release level  or within
  at least two previous Software release levels, or as otherwise specified in the Services agreement.

  Modifiable Software

           10.16.1 Notwithstanding anything  to the  contrary above,  upon payment to Nortel  of the  applicable
  fees, Nortel hereby grants to  Company, subject to the applicable terms and  conditions of this Article 10,  a
  personal,  non-transferable, non-assignable  and non-exclusive  right and license  to modify  Licensed Software
  which Nortel identifies  as modifiable in its  Documentation solely for the purpose of modifying  and creating
  Building  Blocks and Applications.  Upon  the modification or creation of any Applications, or the modification
  or creation of any  Building Blocks, Nortel shall have no obligations with regard to  warranty under Article 8
  or indemnity under Article 12 for such Applications or Building Blocks.

           10.16.2 Nothing  contained in  Sections  10.16.1  through 10.16.5  shall  transfer, or  be  deemed  to
  transfer,  or  contemplate  the transfer  of,  any  rights  in  or  to the  Software  other  than those  rights
  specifically granted  herein, and  in  particular but  without restricting  the generality  of the  foregoing,
  Nortel  does not  in any  way transfer  any  right, title  or interest  in or  to the  Software or  any element
  constituting a  portion thereof  to Company,  other than  the right  of Company  to modify  or create  Building
  Blocks and Applications.

           10.16.3 For any  Building Blocks and  Applications created  solely by Company, and  for all  Company-
  modified portions of the  Nortel-provided Building Blocks  with respect to such modified portion  only, Company
  shall  own all  forms of  intellectual property rights  (including but  not limited  to patent,  trade secret,
  copyright and  mask rights) pertaining  to such  Applications, Building Blocks  or portions thereof and  shall
  have  the right  to file  for or  otherwise secure  and protect  such rights.   For  all such  Company created
  Applications or  Building Blocks, or  modified portions of  Building Blocks, the  parties shall, on  a case  by
  case basis,  negotiate in good faith to determine  whether Company may desire  to license any such Applications
  or Building Blocks to Nortel.

           10.16.4 For any Application created  solely by Nortel and for  the Nortel- provided Building  Blocks,
  Nortel shall  own all  forms of  intellectual property  rights  (including but  not limited  to patent,  trade
  secret, copyright  and mask  rights) pertaining  to such  Applications or  Building Blocks  and shall have  the
  right to file for or otherwise secure  and protect such rights.  For all such Nortel Applications or  Building
  Blocks, Company  may license  any such additional  Nortel Products upon  Nortel making such  software generally
  available to its customers.

           10.16.5 In the  event that  Company and  Nortel intend  to jointly  create  Applications or  Building
  Blocks, the parties shall mutually agree as to applicable terms and conditions.

  Services Software

           10.17.1 With respect to Services Software,  Company shall: i) utilize such  Services Software and the
  results thereof solely  for the purposes described  in Section 1.27; and ii)  comply with additional terms,  if
  any, applicable  to such  Services Software as  specified in  a Product  Annex.  Nortel  may, at  any time and
  without  liability or obligation to Company, modify the Services Software, any  computer equipment of Nortel or
  its suppliers  used in  connection with  such Services  Software, and  identification codes,  manuals or  other
  information or Documentation used in connection with the Services Software.

           10.17.2 SERVICES SOFTWARE IS  PROVIDED AS IS  AND WITHOUT  WARRANTY OR CONDITION  OF ANY KIND,  EITHER
  EXPRESSED  OR IMPLIED, INCLUDING,  BUT NOT LIMITED  TO, THE IMPLIED  WARRANTIES OF  MERCHANTABILITY AND FITNESS
  FOR A PARTICULAR  PURPOSE.  NORTEL DOES NOT AND CANNOT WARRANT THE PERFORMANCE OR RESULTS THAT MAY BE OBTAINED
  BY USING SERVICES SOFTWARE.   COMPANY ASSUMES SOLE  RESPONSIBILITY FOR THE SELECTION  OF THE SERVICES SOFTWARE
  TO  ACHIEVE COMPANY'S INTENDED RESULTS, AND FOR THE INSTALLATION, USE,  AND RESULTS OBTAINED FROM THE SERVICES
  SOFTWARE.   IN  NO  EVENT  SHALL  NORTEL  BE  LIABLE  FOR  ANY INDIRECT,  INCIDENTAL,  SPECIAL,  PUNITIVE,  OR
  CONSEQUENTIAL DAMAGES,  INCLUDING WITHOUT  LIMITATION, LOST REVENUES OR  PROFITS OR OTHER ECONOMIC  LOSS OF ANY
  NATURE WHATSOEVER ARISING OUT OF COMPANY'S USE OF SERVICES SOFTWARE.

                       ARTICLE 11.  HOMOLOGATION AND
                                CERTIFICATION

            11.1  Nortel hereby warrants that it will comply with the homologation requirements for a Product, unless
  otherwise specified in a Product Annex, in each of the countries set forth on Exhibit E.

            11.2  In the event that Nortel or a Nortel Affiliate has complied or complies in the future with the
  homologation requirements for a Product in any country not set forth on Exhibit E, Nortel shall, to the
  extent of its legal right to do so, grant Company the right to use the results of such homologation.   Any
  costs arising from such grant shall be subject to agreement by the parties prior to such grant being made.

              ARTICLE 12.  LIABILITY FOR BODILY INJURY, PROPERTY DAMAGE
                         AND PATENT INFRINGEMENT

            12.1  A party hereto shall defend the other party against any suit, claim, or proceeding brought against the
  other party for direct damages due to bodily injuries (including death) or damage to tangible property which
  allegedly result from the negligence or willful misconduct of the defending party in the performance of this
  Agreement.  The defending party shall pay all litigation costs, reasonable attorney's fees, settlement
  payments and such direct damages awarded or resulting from any such suit, claim or proceeding.

           12.2    Nortel shall defend Company against any suit, claim or proceeding brought against Company
  alleging that the sale to, or use by Company of, any Products, excluding Third Party Hardware or Third Party
  Software, furnished hereunder infringes any patent ("Infringement Claim"). Nortel shall pay all litigation
  costs, reasonable attorney's fees, settlement payments and damages awarded or resulting from any such suit,
  claim or proceeding. With respect to Third Party Hardware or Third Party Software, Nortel shall assign any
  rights with respect to infringement of patents granted to Nortel by the supplier of such items to the extent
  of Nortel's right to do so.

           12.3    Nortel's cumulative liability, pursuant to this Article 12 and including its costs and
  expenses incurred in satisfying its obligations set forth below, shall not exceed one hundred percent (100%)
  of the purchase price of the Product giving rise to the Infringement Claim.

           12.4     Nortel shall not be liable and Company shall indemnify Nortel for any costs incurred by
  Nortel or liabilities of Nortel arising under this Article in excess of the amounts so stated above.

           12.5     Nortel shall have no liability, in respect of any Infringement Claim based on the use of a
  Product in the event that such Product:  (a) is manufactured, designed or supplied by Nortel in accordance
  with any design or any special instruction furnished by Company, (b) is used by Company in a manner or for a
  purpose not contemplated by this Agreement, (c) is used by Company in combination with other products not
  provided by Nortel, including, without limitation, any software developed solely by Company through the
  permitted use of Products furnished hereunder, provided that the Infringement Claim arises from such
  combination or the use thereof, (d) is modified by Company where such modification is not authorized by
  Nortel, or (e) is used or located by Company in a location other than the location in which and for which it
  was supplied by Nortel.  In the excepted cases stated above, Company shall indemnify and hold Nortel harmless
  against any loss, cost, expense, damage, settlement or other liability, including, but not limited to,
  attorneys' fees, which may be incurred by Nortel with respect to any suit, claim, or proceeding described in
  this Section 12.5.

           12.6    Nortel shall not be liable for, and Company shall indemnify Nortel in respect of, any
  damages awarded based on Company's willful, knowing or deliberate infringement of a patent, copyright, trade
  secret, trademark or other proprietary right where such infringement results in a pecuniary damage award.

           12.7    Nortel may provide Company with notice of an actual or potential Infringement Claim.  Nortel
  shall consult with Company regarding the Infringement Claim and the course of action to be pursued as a
  result thereof.  In the event that the parties fail to agree on a satisfactory course of action for dealing
  with the matter, Company may either:

    return to Nortel the affected portion of the Product(s) in return for a refund of the
             depreciated value (as carried on the books of Company) of the Product(s) so
             returned; or

    (ii)     continue to use the Product(s) at Company's own risk.

           12.8    Nortel shall not be liable for, and Company shall indemnify Nortel in respect of any
  Infringement Claim(s) where Nortel has provided notice to Company of the Infringement Claim(s) and Company
  elects to continue its use of the Product(s) covered by the Infringement Claim.

           12.9    If as a result of an Infringement Claim, other than those contemplated above, an injunction
  is obtained against Company's use of any Product, Nortel shall, at Nortel's option: 

             (i)     procure for Company the right to continue using the alleged infringing
             Product(s);

             (ii)    replace or modify the same with equivalent or better Product(s) so that
             Company's use is non-infringing; or

             (iii)   accept return of the affected portion of the Product(s) and refund to
             Company the depreciated value (as carried on the books of Company) of the Product(s)
             so returned.

           12.10   The defense of any claim which is predominantly covered by the provisions of this Agreement
  shall be controlled by the party upon whom the majority of the ultimate liability is likely to be imposed. 
  Such controlling party shall give the other party a reasonable opportunity to participate in negotiation or
  defense of the claim so that such other Party may reasonably protect its own interests.  Neither Party shall
  be liable for any settlement obligation incurred without its written consent.

           12.11   Company shall waive any and all claims that Company may have against Nortel that Company may
  have due to any use by Company of Modifiable Software and any modification Company may have made to a Product
  as a result of such use.  Further, Company shall be responsible for any additional hardware, software or
  services required as a result of such use.

           12.12   THE REMEDIES SET FORTH IN THIS ARTICLE 12 ESTABLISH THE ENTIRE OBLIGATION OF THE PARTIES IN
  REGARD TO CLAIMS RELATING TO INTELLECTUAL PROPERTY RIGHTS INCLUDING CLAIMS DIRECTED TO THE INFRINGEMENT OF
  PATENTS, COPYRIGHT, TRADE SECRETS AND OTHER PROPRIETARY RIGHTS.  IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR
  ANY INDIRECT, INCIDENTAL, SPECIAL, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR FOR LOST REVENUES, PROFITS OR OTHER
  ECONOMIC LOSSES, ARISING FROM SUCH INFRINGEMENTS AND/OR OTHER MATTERS, OTHER THAN AS SPECIFICALLY SET FORTH
  HEREIN.

                    ARTICLE 13.REMEDIES AND LIMITATION OF LIABILITY

           13.1  Nortel shall have the right to suspend its performance, upon written notice to Company, and forthwith
  remove and take possession of all Products that shall have been delivered to Company, if, prior to payment to
  Nortel of any amounts due pursuant to this Agreement with respect to such Products, Company shall (a) become
  insolvent or bankrupt or cease, be unable, or admit in writing its inability, to pay all debts as they
  mature, or make a general assignment for the benefit of, or enter into any arrangement with, creditors, (b)
  authorize, apply for, or consent to the appointment of, a receiver, trustee, or liquidator of all or a
  substantial part of its assets or have proceedings seeking such appointment commenced against it which are
  not terminated within sixty (60) days of such commencement, or (c) file a voluntary petition under any
  bankruptcy or insolvency law or under the reorganization or arrangement provisions of the United States
  Bankruptcy Code or any similar law of any jurisdiction or have proceedings under any such law instituted
  against it which are not terminated within sixty (60) days of such commencement.

           13.2    In the event of any material breach of this Agreement which shall continue for thirty (30)
  or more days after written notice of such breach (including a reasonably detailed statement of the nature of
  such breach) shall have been given to the breaching party by the aggrieved party, the aggrieved party shall
  be entitled at its option to avail itself of any and all remedies available at law or equity, except as
  otherwise limited in this Agreement.  

           13.3    Nothing contained in Section 13.2 or elsewhere in this Agreement shall make Nortel liable
  for any indirect, incidental, punitive, special or consequential damages of any nature whatsoever for any
  breach of this Agreement whether the claims for such damages arise in tort (including negligence regardless
  of degree of fault), contract, or otherwise.

           13.4    Nortel shall not be liable for any additional costs, expenses, losses or damages resulting
  from errors, acts or omissions of Company, including, but not limited to, inaccuracy, incompleteness or
  untimeliness in the provision of information by Company to Nortel or fulfillment by Company of any of its
  obligations under this Agreement.  Company shall pay Nortel the amount of any such costs, expenses, losses or
  damage incurred by Nortel.

           13.5    Any action for breach of this Agreement or to enforce any right hereunder shall be commenced
  within two (2) years after the cause of action accrues or it shall be deemed waived and barred, except any
  action for nonpayment by Company of any prices, charges, fees or other amounts payable hereunder may be
  brought by Nortel at any time permitted by applicable law, and Nortel may suspend performance of any of its
  obligations hereunder until all such payments are made.

                        ARTICLE 14.  TERM AND TERMINATION

           14.1   This Agreement will be in effect from the Effective Date for a period of eighteen (18) months (the
  "Original Term").  Thereafter, this Agreement shall automatically renew for one (1) year terms (each, a
  "Renewal Period" and collectively and together with the Initial Term, the "Term"), unless either party
  provides the other party with written notice of its intent not to renew at least sixty (60) days prior to the
  end of the Original Term or any Renewal Period.
   
           14.2     Either party may delay performance under this Agreement or terminate this Agreement, in
  whole or in part, in the event of a default by the other, provided that the non-defaulting party so advises
  the defaulting party in writing of the event of alleged default and the defaulting party does not remedy the
  alleged default within thirty (30) days after written notice thereof. If the alleged default is not capable
  of being remedied within thirty (30) days, the defaulting party must commence to remedy the alleged default
  within such thirty (30) day period and provide to the non-defaulting party a plan for timely remedying the
  alleged default in order to avoid termination.  A default shall include:

             (i)     a party's insolvency or initiation of bankruptcy or receivership proceedings
             by or against a party or the execution of an assignment for the benefit of
             creditors; or

    either party's material breach of any of the terms or conditions hereof including the
             failure to make any payment when due.

           14.3    The expiration or termination of this Agreement for any cause shall not release either party
  from:

    any obligations and duties remaining under any Order entered into prior to such expiration
             or termination;

    any liability which at the time of termination has already accrued to the other party, or,
             which thereafter may accrue in respect to any event prior to termination; or

    any liability from any obligation specified in Section 16.18 below to survive expiration or
             termination.

                           ARTICLE 15.  CONFIDENTIALITY

           15.1    Each party which receives the other party's Confidential Information shall use reasonable
  care to hold such Confidential Information in confidence and not disclose such Confidential Information to
  anyone other than to its employees and employees of a Company Affiliate or a Nortel Affiliate, as applicable,
  with a need to know. A party that receives the other party's Confidential Information shall not reproduce
  such Confidential Information, except to the extent reasonably required for the performance of its
  obligations pursuant to this Agreement and in connection with any permitted use of such Confidential
  Information. 

           15.2    Company shall take reasonable care to use Nortel's Confidential Information only for study,
  operating, or maintenance purposes in connection with Company's use of Products furnished by Nortel pursuant
  to this Agreement.

  Confidential Information which may be retained in intangible form by those employees who have had access to
  the Confidential Information, for any purpose, including use in the development, manufacture, marketing and
  maintenance of its products and service. The marketing of any product or service, including the dissemination
  of supporting documentation, which inherently discloses the disclosing party's Confidential Information shall

  Confidential Information and all intellectual property rights to such Confidential Information remain with
  the disclosing party.

           15.4    The obligations of either party pursuant to this Article 15 shall not extend to any

  the recipient prior to its disclosure to the recipient and without confidential obligations was known or
  generally available to the public at the time of disclosure to the recipient, becomes known or generally
  available to the public (other than by act of the recipient) subsequent to its disclosure to the recipient,
  is disclosed or made available in writing to the recipient by a third party having a bona fide right to do so
  and without similar confidentiality obligations, is independently developed by recipient, or is required to
  be disclosed by process of law, provided that the recipient shall notify the disclosing party promptly of any
  such subpoena or other process of law requiring disclosure.

      Article 4 of the Agreement.

      2.  In the event  that Company does not satisfy the  Commitment set forth in Section  1 of this Product Annex A.1,
      upon  the expiration of the Term,  Nortel shall invoice Company  for, and Company shall  pay to Nortel, an
      amount equal  to the price difference  obtained by subtracting: (i)  the total prices paid  by Company for
      all  Products purchased by  Company during the  Term, excluding  any and all Orders  cancelled pursuant to
      Article 7 of the Agreement during the Term, from (ii)           [*]              .  Company  shall pay  to
      Nortel the entire invoiced amount within thirty (30) days after the date of invoice.

      3. From time  to time  during the  Term,  Company may  license any  of the  DMS-GSP  Optional  Software listed  in
      Attachment 1,  Part IV ("Optional Software").   In the event  that Company includes an  Order for Optional
      Software with Company's Order for a DMS-GSP, Company shall receive a     [*]              discount  off the
      licensing fees for such Optional Software as set forth  in Attachment 1, Part IV.  For all  other Optional
      Software Orders issued by Company during the Term, Company shall receive a       [*]      discount  off the
      licensing fees set forth in Attachment 1, Part IV.

      4.  From time to time during the Term, Company may issue an Order for no more than [*]              
      generic  Software upgrades  per each  DMS-GSP  purchased by  Company  under this  Product  Annex A.1  (the
      "Software  Upgrade").   Each  Software  Upgrade shall  be within  two  (2) previous  Software  releases of

      Upgrade.  Nortel shall issue an invoice to Company  for the price of any gating Hardware that  is required
      for Software feature functionality  of the Software Upgrade,  and Company shall pay  to Nortel the  entire
      invoiced amount within thirty  (30) days after the date of invoice.   Company may elect to issue  an Order
      for  each Software Upgrade  upon the  Acceptance date  of Company's  initial DMS-GSP purchased  under this
      Product Annex A.1.  In the event  that Company has not issued an Order for  delivery and installation of a
      Software  Upgrade  prior to  the  expiration of  the Term,  Company  shall forfeit  any and  all remaining
      Software Upgrades.

           for such Extension Ports in accordance with Article 4 of the Agreement.

  6.0      Exclusive Purchases - In consideration of Nortel's pricing  of its Products and Services as set  forth
           and described in this  Product Annex, and in order to ensure that  Nortel's warranty and other support
           obligations pursuant to the Agreement apply  to all telecommunications switching Products installed in
           the Company's network, Company  shall purchase, during the Term,  any and all of its  requirements for
           telecommunications  switching Products  and Services  that will  be used  by Company  for the  same or

           to be produced by Nortel, including, but not limited to the telecommunications switching  Products and
           Services set forth in  this Product Annex.   In the event  that Nortel, as a  result of a  substantial
           difference in the purchase price of the  telecommunications switching Products and Services, is unable
           to  provide such telecommunications switching Products and Services  to Company, and both parties have
           made a good  faith effort  to negotiate a  resolution, Nortel  will consent to  Company's purchase  of
           substitute products from other vendors.

           terms of its telecommunications  switching Products and Services, which are set  forth in this Product
           Annex, for any purchases that occur after Company violates the exclusivity provision of this section.

deviations to an Order, subject to the condition that such changes and any

written notice to Company. Such notice shall specify the effective date of the
price change and shall apply to all Orders received by Nortel on or after the
effective date of the price change.

     4.3  Unless otherwise set forth in a Service Annex or a Statement of Work,
Nortel shall invoice Company for one hundred percent (100%) of the price of

Agreement, and such payment default continues unremedied for a period of at
least [**] days or such other breach continues for a period of at least [**]
days, the Grantor, or its authorized agent, may notify the Purchaser in writing
of such payment default or other breach and if full payment is not received or
such other breach is not fully remedied within 15 (fifteen) days of such

over any of the facilities comprising the System, or impair privacy of any
communications over such facilities, cause damage to plant or create hazards to
employees, affiliates or connecting companies of the Grantor, any Subsidiary
Grantor, the Purchaser, or any other user, owner or operator of the System or
the public.  The Purchaser shall bear the cost of any additional protective
apparatus reasonably required to be installed because of the use of such
facilities by the Purchaser, any lessees or permitted transferees of the
Purchaser, or any customer or customers of the Purchaser or of any such lessee
or transferee.  The Grantor will use reasonable efforts to cause all other
purchasers of capacity in the System to undertake obligations comparable to
those of the Purchaser set forth in this Section, and the Purchaser shall cause
all permitted users of the IRU in the Purchased Capacity to undertake comparable
obligations.
 
         The Purchased Capacity granted to the Purchaser shall be made available
to the Grantor (or it subsidiaries, its agents or the Operator), at such times
agreeable to the Purchaser and the Grantor, to permit the Grantor and the
Subsidiary Grantors to conduct such tests and adjustments as may be necessary

         This Agreement shall become effective on the day and year set forth in
the preamble hereto and shall continue in operation until the [**]anniversary of
the RFS Date for the entire System (the "Term").
 
         The termination of this Agreement (whether under this Section or
otherwise) shall not relieve the Purchaser, the Grantor or the Subsidiary
Grantors from any liabilities arising prior to such termination.

         Upon the termination of this Agreement, so long as Purchaser is not in
default hereunder, the Purchaser may elect to extend its rights in the System,
for so long as the System exists or has not been retired, by giving written
notice to Grantor any paying to Grantor one (1) dollar.  Such election to extend
shall not affect or delay the termination of the Grantor's obligations under
this Agreement.  Upon such election to extend and payment, the Purchaser,
together with all other purchaser of capacity on the System that also elect to
so extend, shall become the sole owner of the System.  The ownership interests
of the Purchaser and such other purchasers shall be in proportion to the amount
of capacity covered by IRU's previously granted to the Purchaser and such other
purchasers.  The Grantor shall execute and deliver such documentation as may be
reasonably required to effect such transfer of ownership.  Without limitation to
the generality of the foregoing provisions, Grantor shall have no obligation to
operate or maintain the System during such extension.

         The parties hereto shall discuss with each other and the other
purchasers of capacity on the System establishing a procedure for the early
retirement of the System if such retirement appears to be commercially

and inure to the benefit of the parties hereto, the Subsidiary Grantors and
their respective successors and permitted assigns; provided that, except for the
assignment of the Purchaser's or the Grantor's and/or any Subsidiary Grantor's
rights under this Agreement to one or more of the Purchaser's or the Grantor's
lenders as security and except as proved in one of paragraphs (b), (c), (d) or
(e) of this Section, neither this Agreement nor any of the rights or interests

obligations hereunder delegated by either party hereto without the prior written
consent of the other party.
 
         Each party hereto shall be permitted to assign, transfer or otherwise
dispose of any or all of their rights hereunder and under the Right of Use
Agreement and delegate any or all of their obligations hereunder and under the
Right of Use Agreement to any present or future affiliated company of such party
or to an entity controlled by, under the same control as, or controlling, such
party; provided that any such assignment, transfer or other disposition shall
not release such party from its obligations hereunder, unless the other party
consents otherwise in writing, which consent shall not be unreasonably withheld
(it being understood that it is not unreasonable to withhold consent if the
assignee or transferee is not as creditworthy as the assignor).  Each party
shall give the others notice of any such assignment, transfer or other
disposition or any such delegation.

         Except as specifically under paragraph (a), (b), (c), (d) or (e) of
this Section, the Purchaser shall not be permitted to:
 
                  (1)      Assign, transfer or otherwise dispose of any or all
of its rights hereunder or under the Right of Use Agreement; provided that the
Purchaser shall be permitted to (A) enter into one or more lease or license
agreements to lease or license Purchased Capacity to a lessee so long as each

not its obligations) to use any Purchased Capacity to a Carrier Party in
accordance with paragraph 6 of Annex B to this Agreement, provided that the
aggregate maximum amount of capacity that may be transferred to all Carrier
Parties shall not exceed one MCU and provided further that simultaneously with
transferring such rights to such Carrier Party, such Carrier Party executes a
document acknowledging:

                                    (i)     that is has acquired from the
Purchaser rights to use Purchased Capacity which were conveyed to the Purchaser

          that the Purchaser has an ongoing obligation under the CPA to make
certain payments to the Grantor (including, without limitation, in respect of
operation, administration and maintenance expenses and in respect of remaining
payments for the Purchase price of such Purchased Capacity) and otherwise comply
with the terms thereof, and that the failure of the Purchaser to make any such
payments when due or the occurrence of any other breach by the Purchaser of the
terms of the CPA could result in the suspension of Purchaser's right to the
Purchased Capacity or reclamation by the Grantor of the Purchased Capacity in
accordance with the terms of the CPA; and
 
         that such Carrier Party is not a third party beneficiary of the CPA or
the right of use Agreement; or

                  delegate any or all of its obligations hereunder or under the
Right of Use Agreement to any person or entity.

         In addition to any rights of assignment under Section 20(b), upon

purchased hereunder, or, prior to such payment, upon execution and delivery by
the Purchaser of a Parent Guaranty (or if a Parent Guaranty is already in

Guaranty or a written consent), the Purchaser shall be permitted to assign,
transfer or otherwise dispose of any or all of its rights hereunder and under
the Right of Use Agreement and delegate any or all of its obligations hereunder
and under the Right of Use Agreement to any present or future affiliated company
of the Purchaser or to an entity controlled by, under the same control as, or
controlling, the Purchaser.  The Purchaser shall give the Grantor notice of any
such assignment, transfer or other disposition or any such delegation.

         In addition to any rights the Purchaser may have under any other
paragraph of this Section, (i) after the date on which all capacity (including
additional capacity created when the System is upgraded) on the System has been
sold by the Grantor or (ii) prior to such date, so long as a Purchaser has not
acquired more than one MCU of Purchased Capacity on a Transatlantic Segment
hereunder, and provided that it waives all rights to acquire additional MCUs of
Purchased Capacity under the terms of Sections 2(f) and 2(g) hereof, such
Purchaser shall be permitted to assign, transfer or otherwise dispose of all if
its rights hereunder and under the Right of Use Agreement and delegate all of
its obligations hereunder and under the Right of Use Agreement or any other
Person; provided that any such assignment, transfer, other disposition or
delegation shall not release such Purchaser from its obligations hereunder,
unless the Grantor consents otherwise in writing, which consent shall not be
unreasonably withheld (it being understood that it is not unreasonable to
withhold consent if the assignee or transferee is not as creditworthy as the

                                         INDEFEASIBLE RIGHT OF USE AGREEMENT

         THIS AGREEMENT (as amended, supplemented or otherwise modified from
time to time, this "Agreement") is made and entered into as of this 7th day of
April, 1998, between and among GT Landing Corp., GT U.K. Ltd., Global

Grantors") and the Purchaser signatory hereto.

                                                     WITNESSETH:

         WHEREAS, each Subsidiary Grantor is a wholly-owned subsidiary of Global
Telesystems Ltd. (the "Parent") who is the grantor under the Capacity Purchase
Agreement (as amended, supplemented or otherwise modified form time to time, the
"Capacity Purchase Agreement") to which a copy of this Agreement is attached;

         WHEREAS, capitalized terms used in this Agreement and not otherwise
defined in this Agreement shall have the meanings assigned to them in the
Capacity Purchase Agreement;

         WHEREAS, upon completion of the construction and installation of the
System, GT Landing Corp. will have an IRU in the whole of Segment T-1, GT U.K.
Ltd. will own Segment T-2, Global Telesytems GmbH will own Segment T-3 (except
with respect to that portion of Segment T-3 which comprises Subsegment T-3A in
which Global Telesystems GmbH has rights to) and GT Netherlands B.V. will own
Segment T-4 (except with respect to that portion of Segment T-4 which comprises
Subsegment T-4A in which GT Netherlands B.V. shall have rights to);

         WHEREAS, subject to and in accordance with the terms of the Capacity
Purchase Agreement, the Parent is conveying certain S Capacity to the Purchaser
on an indefeasible right of use basis;

         WHEREAS, each Subsidiary Granter desires to grant to the Purchaser, at
no additional charge and for so long as the Purchaser maintains an IRU in any S
Capacity, an indefeasible right of use with respect to its respective T Segment
to the extent required by the Purchaser to use its IRU in such S Capacity; and

         WHEREAS, the Subsidiary Grantors acknowledge and agree that the
Purchaser has relied upon this Agreement in entering into the Capacity Purchase
Agreement;

         NOW, THEREFORE, for good and valuable consideration the receipt and
sufficiency of which and hereby acknowledged, the Subsidiary Grantors covenant
and agree as follows:

1.   Upon the effectiveness of the grant to the Purchaser of an indefeasible
     right of use with respect to any S Capacity (including in any Residual
     Capacity) in accordance with the Capacity Purchase Agreement, each
     Subsidiary Grantor grants to the Purchaser, at no additional charge and for
     the Term of the Capacity Purchase Agreement so long as the Purchaser
     maintains an IRU is such S Capacity, an indefeasible right of use with
     respect to its respective T Segment to the extent required by the Purchaser
     to use its IRU in the S Capacity.

2.   Subject to Sections 10 and 11 of the Capacity Purchase Agreement, each
     Subsidiary Grantor shall maintain, or cause the Operator to maintain, its
     respective T Segment in accordance with the provisions set forth in the
     Capacity Purchase Agreement and the OA&M Agreement.

3.   The grant under this Agreement by the Subsidiary Grantors is contingent
     upon the continued operation of the System, the continuance of the Capacity
     Purchase Agreement and upon the obtaining and continuance of such
     approvals, consents, governmental authorizations, licenses and permits as
     may be required or deemed necessary by the parties and as may be
     satisfactory to them.  No license under patents is granted by the
     Subsidiary Grantor or shall be implied or arise by estoppel in the
     Purchaser's favor with respect to any apparatus, system or method used by
     the Purchaser in connection with the use of the T Segment(s) granted
     hereunder.

4.   The Subsidiary Grantors and the Parent have entered in the Supply Contract
     to obtain plant, equipment and services necessary to allow the T Segments
     to be placed into operation on the applicable scheduled RFS Date.  The
     Subsidiary Grantors do not warrant or guarantee that the RFS Date will
     occur for any T Segment and the Subsidiary Grantors will otherwise have no
     obligation under this Agreement or otherwise unless and until the
     applicable RFS Date occurs.  UNLESS SPECIFICALLY SET FORTH IN THIS
     AGREEMENT, ANY OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING BUT NOT
     LIMITEDTO, THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
     PURPOSE ARE SPECIFICALLY DISCLAIMED.

5.   In no event shall any Subsidiary Grantor be liable to the Purchaser for
     consequential, incidental, indirect or special damages, including but not
     limited to, loss of revenue or loss of business opportunity, or the cost
     associated with the use of external (outside the System) restoration
     facilities.

6.   This Agreement shall not form a joint venture or partnership or similar
     business arrangement between the parties hereto or between the parties
     hereto, the Parent and the Purchaser, and nothing contained herein shall be
     deemed to constitute a partnership or joint venture or similar business
     arrangement nor shall any party be deemed to be the agent or partner of any
     Purchaser.  No party hereto shall have the right to bind any Purchaser.

7.   Except with respect to the Purchaser as provided I Section 12, this
     Agreement does not provide and is not intended to provide third parties
     (including, but not limited to, customers of the Purchaser, any permitted
     transferee (other than a permitted transferee of all of the Purchaser's
     rights and obligations under the Capacity Purchase Agreement) of the
     Purchased Capacity or any other permitted user of Purchased Capacity) with
     any remedy, claim, liability, reimbursement, cause of action, or any other
     right.

8.   This Agreement and all of the provisions hereof shall be binding upon and
     inure to the benefit of the Purchaser and the Subsidiary Grantors and their
     respective successors and permitted assigns under the Capacity Purchase
     Agreement.           

9.   This Agreement shall not be modified or amended except by a writing signed
     by authorized representatives of the parties hereto, provided that in no
     event shall any such amendment that is adverse to the interests of the
     Purchaser be effective as against the Purchaser unless and until the
     Purchaser shall have consented in writing to such amendment. 

10.  This Agreement shall become effective on the date set forth above and shall
     continue in effect for the Term of the Capacity Purchase Agreement, and
     shall immediately terminate without any further action upon the termination
     of the Capacity Purchase Agreement.

11.  The provisions of Section 11, 12, 14, 20, 23 and 25 of the Capacity
     Purchase Agreement are hereby incorporated herein by reference, Mutatis
     Mutandis, and shall be deemed a part of this Agreement as if fully act
     forth herein.

12.  This Agreement is intended to be for the express benefit of each of the
     Purchaser signatories to this Agreement and, upon execution by each
     Subsidiary Grantor and each such Purchaser, shall be deemed to be a
     contract between each such Subsidiary Grantor and each such Purchaser under
     the laws of the State of New York, enforceable directly by such party in
     its own name.

         IN WITNESS WHEREOF, the parties have executed this Agreement effective
on the date first written above.

actual costs of operating, maintaining and repairing the System by the number of
STM-1's sold on the entire System as of such date to all users of the System and
then multiplying the quotient by the number of MCUs in which the purchaser
acquired an IRU.  The Assumed Maintenance Costs for the first calendar year will
be assumed to be [*].

         Within 30 days after the end of each calendar year, Grantor shall
provide the Purchaser with an itemized statement of the actual Maintenance Costs
for the prior calendar year.  If it is determined that the amount paid by the
