infringement or violation to the extent that it: (1) arises from adherence to
design modifications, specifications, drawings, or written instructions which
LUCENT is directed by Reseller to follow, but only if such alleged infringement

design or selection; or (2) arises from adherence to instructions to apply
Reseller's trademark, trade name, or other company identification; or (3)
resides in a Product which is not LUCENT's origin and which is furnished by
Reseller to LUCENT for use under this Contract; or (4) relates to uses of

         previously furnished Product;

         (d) Cease holding itself out, in any other manner, as a Reseller of the

         (e) Notify and arrange for all publishers and others who may identify,
         list or publish Reseller's name as a Reseller of the Products
         (including but not limited to publishers of telephone directories,
         yellow pages and other business directories) to discontinue such
         listings.

The respective obligations of Reseller and LUCENT under this contract which by
their nature would continue beyond the termination, cancellation or expiration
hereof, shall survive termination, cancellation or expiration hereof.


27. FORCE MAJEURE

Except with respect to Reseller's obligation to make timely payments, neither
party shall be held responsible for any delay or failure in performance to the
extent that such delay or failure is caused by fires, strikes, embargoes,
explosions, earthquakes, floods, wars, water, the elements, labor disputes,
government requirements, civil or military authorities, acts of God or by the
public enemy, inability to secure raw materials or transportation facilities,
acts or omissions of carriers or suppliers or other causes beyond its control
whether or not similar to the foregoing.

                                                      CONTRACT NO. LSW97CWORLDWT
                                                                              22


28. ASSIGNMENT (CONTINUED)

prior to written consent of LUCENT. Any attempted assignment or delegation in
contravention of the above provision shall be void and ineffective.

LUCENT has the right to assign this Contract and to assign its rights and
delegate its duties under this Contract, in whole or in part, at any time and
without Reseller's consent, to any corporate parent, to any present or future
affiliate or subsidiary of LUCENT, or to any combination of the foregoing.
LUCENT shall give Reseller prompt written notice of the assignment. The
assignment of any rights and the delegation of any duties shall be subject to
the provisions, terms and conditions of this Contract.


29. SEVERABILITY

If any of the provisions of this Contract shall be invalid or unenforceable such
invalidity or unenforceability shall not invalidate or render unenforceable the
entire Contract, but rather the entire Contract shall be construed as if not
containing the particular invalid or unenforceable provision or provisions, and
the rights and obligations of each party shall be construed and enforced
accordingly. However, in the event such provision is considered an essential
element of this Contract, the parties shall promptly negotiate a replacement
thereof.


30. RELEASES VOID

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


31. LIENS

All Products provided by LUCENT to Reseller shall be free of all liens and
encumbrances.


32. TAXES

The prices set forth in Appendix A do not include applicable taxes and such
prices shall not be subject to change as a result of any change in Reseller's or
LUCENT's tax liabilities. To the extent sales taxes and or any other tax are
applicable to sales made by Reseller to SWBT, the collection or other processing
of such tax shall be the responsibility of Reseller.

                                                                              23


33. NONWAIVER

No course of dealing, course of performance or failure of either party strictly
to enforce any term, right or condition of this Contract shall be construed as a
waiver of any term, right or condition.


34. CHOICE OF LAW

The construction, interpretation and performance of this Contract shall be
governed by the laws of the State of Missouri.


35. NOTICES

All notices under this Contract shall be in writing and shall be given by

to the addresses set forth at the beginning of this Contract or to such other
address as either party may designate by notice pursuant hereto. Such notices

36. DISPUTE RESOLUTION

A. Any controversy or claim, whether based on contract, tort, strict liability,
fraud, misrepresentation, or any other legal theory, related directly or
indirectly to this Contract ("Dispute") shall be resolved solely in accordance
with the terms of this Section 36.

B. If the Dispute cannot be settled by good faith negotiation between the
parties, Lucent and you will submit the Dispute to non-binding mediation. If
complete agreement cannot be reached within thirty (30) days of submission to
mediation, any remaining issues will be resolved by binding arbitration in
accordance with Sections 36C and 36D, except that Lucent reserves the right to
obtain an injunction in court to prevent you use of the Products in violation of
this Contract. The Federal Arbitration Act, 9 U.S.C. Sections 1 to 15, not state
law, will govern the arbitrability of all Disputes.

C. A single arbitrator who is knowledgeable in the telecommunications field or
in commercial matters will conduct the arbitration. The arbitrator's decision
and award will be final and binding and may be entered in any court with
jurisdiction. The arbitrator will not have authority to modify or expand any of
the provisions of this Agreement (e.g., Section 14 The Limitation of Liability
provision of this Agreement).

D. Any mediation or arbitration commenced pursuant to this Agreement will be
conducted under the then current rules of the alternate dispute resolution
(ADR) firm selected by the parties.  If the parties are unable to agree on an
ADR firm, the parties will

36. DISPUTE RESOLUTION (CONTINUED)

conduct the mediation and, if necessary, the arbitration under the then current
rules and supervision of the American Arbitration Association (AAA). Lucent and
you will each bear its own attorneys' fees associated with the mediation and, if
necessary, the arbitration. Lucent and you will pay all other costs and expenses
of the mediation/arbitration as the rules of the selected ADR firm provide.


37. OPTION TO EXTEND

Subject to the conditions stated herein, Reseller will have the right to extend
the period specified in the clause herein entitled Period of Agreement for
twenty four (24) months by giving LUCENT written notice at least thirty (30)
days' prior to the end of this Contract's Initial Period. Within ten (10) days
of the date of Buyer's notice to extend the Initial Period, LUCENT will notify
Reseller in writing whether LUCENT proposes to increase its prices under this
Contract. If it does and the parties fail to agree on the increased prices
within twenty (20) days after the date of LUCENT's notice to Reseller, then
Reseller's notice to extend will be considered withdrawn and the Contract shall
come to a conclusion in accordance with its terms and prices for outstanding
Orders will not be revised.


38. ATTORNEY'S FEES

If legal action is commenced to enforce the performance of any part of this
Contract, the prevailing party shall be paid by the other party reasonable
