3.1 This Agreement is not intended to establish an exclusive relationship.
Nothing in this Agreement shall be construed as limiting, in any manner,
Company's marketing or distribution activities or its appointment of other
dealers, distributors, licensees or agents, provided that in engaging in such
activities or appointments, Company and its other dealers, distributors,
licensees or agents do not violate Company's obligations to Lucent as set out in
this Agreement. Nothing in this Agreement shall be construed as limiting, in any
manner, Lucent's pursuit of, negotiation with, and establishment of sales
referral agreements or other arrangements with other companies, or to market its
own products or those of other third parties to Lucent Customers even though
such products may be comparable to Products. Company acknowledges that nothing
herein shall be deemed to bar Lucent from proposing to the same Lucent Customer,
at the same time that it is referring Products, the products of one or more
other suppliers, including Lucent. Company further acknowledges that Lucent
markets through its own sales personnel and through its Affiliates and that the
right of Lucent to refer Lucent Customers to Company, and to receive sales
referral commissions in respect of transfers of Products to Registered Lucent

Affiliates. As used herein, the term Lucent shall include such Affiliates unless
the context otherwise requires.

after providing such description, Lucent may refer Lucent Customers to Company
as specified in Exhibit D. Each Lucent Customer referred to Company and accepted
by Company pursuant to such procedure shall, to the extent of such acceptance,
become a Registered Lucent Account.

3.3 Notwithstanding the provisions above, Company shall either accept or reject
each referral of a Lucent Customer or Lucent Customer Service Area within five
(5) business days, stating its reason(s) therefor. Reasons for rejection of a
Lucent Customer referral may include, but are not limited to:

         (a)  the Lucent Customer or Lucent Customer Service Area is a
              Restricted Company Account;

         (b)  the Lucent Customer's financial status is unacceptable; and/or

         (c)  the product development requirements of the Lucent Customer will
              require extensive development by Company.

In the event Company rejects a Lucent Customer referral for reason (a) above,
Company will be able to pursue that account directly without Lucent's approval.
In the event Company rejects a Lucent Customer referral for any reason other
than (a) above, Company agrees it will not pursue that Lucent Customer directly
for a period of one (1) year after its rejection. In the event that Company does
not respond to Lucent within five (5) business days to accept or reject the
Lucent Customer referral, for purposes hereof it will be assumed that Company
has accepted the referral and the referred Lucent Customer or Lucent Customer
Service Area shall be deemed a Registered Lucent Account.

accompany Lucent's personnel on visits to Registered Lucent Accounts and provide

such customers, and otherwise take affirmative steps intended to cause such
customers to purchase Products.

3.5 In the event that the parties shall mutually agree that a Registered Lucent
Account should no longer be considered such, effective with the date of such
agreement, the Lucent Customer or Lucent Customer Service Area involved shall no
longer be deemed a Registered Lucent Account and Company will then, at its sole
discretion, be able to pursue that account directly or through another
distribution channel without owing any commission or other such payments to
Lucent, provided, however, that nothing herein shall be deemed to excuse
Company's obligation under Article 6.0, COMMISSION to pay commissions in respect
of Products or additional growth, upgrades and new features furnished by Company
for Products transferred to the Lucent Customer or Lucent Customer Service Area
pursuant to arrangements entered into prior to the time the Lucent Customer or
Lucent Customer Service Area ceases to be a Registered Lucent Account.

their acts and be responsible for payment of all unemployment, Social Security,
and other payroll taxes, including contributions required by law.

4.2 No director, officer, employee, consultant or agent of either Party hereto
or their respective Affiliates shall at any time be deemed to be a director,
officer, employee, consultant or agent of the other Party for any purpose
whatsoever, and the Parties shall use commercially reasonable efforts to prevent
any such misrepresentation. Nothing in this Agreement shall be deemed to create
any joint venture, partnership, or principal-agent relationship between the
Company and Lucent, and neither Party shall hold itself out in its advertising
or in any other manner which would indicate any such relationship with the
other. Company shall at all times be considered an independent contractor for

failure in performance to the extent that such delay or failure is caused by a
Force Majeure. Each such Party shall notify the other such Party within thirty

results in a delay or failure in performance, the Parties may mutually agree to
resume performance once the Force Majeure ceases with an option for the injured
Party to extend the performance date up to the length of time the Force Majeure
endured. Unless written notice is given within thirty (30) days after such
injured Party is apprised of the occurrence of a Force Majeure, the
aforementioned option shall be deemed selected. Nothing contained herein or
elsewhere shall impose any obligation on either Party to settle any labor
difficulty.

21.0 NON-WAIVER

21.1 No waiver of the terms and conditions of this Agreement, or the failure of

Information (1) shall not be reproduced or copied, in whole or part, except for
use as authorized in this Agreement; and (2) shall, together with any full or
partial copies thereof, be returned or destroyed when no longer needed. Unless
the furnishing Party consents in writing, such Information, except for that
part, if any, which is known to the receiving Party free of any confidential
obligation, or which becomes generally known to the public through acts not
attributable to the receiving Party, shall be held in confidence by the

the Parties' cooperation under this Agreement, and will not be used for any
other purpose, including the solicitation or servicing of Lucent Customers or
prospective customers, except as expressly authorized in writing by Lucent.

OR ANY OTHER INDIRECT LOSS OR DAMAGE ARISING OUT OF THIS AGREEMENT OR ANY
OBLIGATION RESULTING THEREFROM, WHETHER IN AN ACTION FOR OR ARISING OUT OF

           EXHIBIT A - PRODUCT DESCRIPTION AND LIST PRICE INFORMATION

SMS WEB GATEWAY

The SMS Web Gateway works in conjunction with the Short Message Service Center
and uses SMPP, the preferred protocol for sending short text messages. The SMS
Web Gateway accepts messages from e-mail or web pages, translates the messages
from SMTP or HTTP to SMPP and then forwards the messages to the SMSC for
delivery to the handset.

E-mail messages can be sent from standard E-mail clients through the SMS Web
Gateway to SMSC and then to the handset. E-mail attachments are not sent and the
message will be truncated if it is longer than the current acceptable length.

The SMS Web Gateway resides on a platform distinct from that of the SMSC
application. The SMS Web Gateway is a Java application that will run on a server
with a Java interpreter. The SMS Web Gateway must reside on a server with web
server software that supports servlets. Servlet plug-ins are available for many
of the major web servers. If the SMS Web Gateway is to be used for SMTP to SMPP
translation, i.e. e-mail transfers, then no other mail server can reside on the
same server.

CUSTOMIZED PERSONAL LIST PAGES

The Customized Personal List Pages are intelligent, client-side web pages which
can be used in conjunction with the SMSC. The Personal List pages allow the user
to categorize their personal entries.

The Customized Personal Lists allow any number of end users to store the names
and associated MIN numbers of their personal contacts. This allows users to
customize the web page to their individual needs. By using client side cookies,
the pages do not add any additional storage or processing overhead to the server
due to data lookups.

Once the user has entered a contact, the user would simply select the contact's
name from a list and the MIN would automatically be entered in the To: field.
The user would then type a short text message on the form and submit the form
when complete. The Customized Personal Lists works in conjunction with a web
server and the SMS Web Gateway. The submitted message would then be routed to
the SMS Web Gateway for protocol translation and forwarding to the SMSC.

CUSTOM USER PAGE APPLICATION

The Custom User Page Application (CUPA) application can be configured to operate
with the SMS Web Gateway. This application resides on a web server that supports
servlets. It queries a relational database and allows individual users to
configure customized web pages for themselves containing such information as
their e-mail, address, message of the day and a URL. The generated pages allow
individuals to send short text messages directly to the owner of the page.
