                             DISTRIBUTOR AGREEMENT

This reseller and distributor agreement ("Agreement") is entered into this 15th
day of January, 1999 between Contego, LLC ("Contego") and Intelispan, Inc.
("Intelispan").

1.   PURPOSE

          1.1.  PKI Product. Contego develops and markets a software program
operating over a TCP/IP network known as "Contego-PKI", which includes TD
Client, certain interfaces and server software. TD Client permits a client
computer to authenticate its identity, using a pre-established key, with a
server computer running certain software from Zergo, PLC ("Zergo") that Contego
distributes.

          1.2.  Premium Authentication Service. Contego has integrated TD Client
with certain Zergo products into the private advanced network (the "GridNet
Network") owned and operated by MCI WorldCOM to provide a specialized
authentication service (the "Premium Authentication Service").

          1.3.  Distribution Rights. Contego has the right to license certain
distributors to sell the Premium Authentication Service, provided such
distributors are licensed resellers of the GridNet Network.

          1.4.  Subdistributor. Intelispan desires to be appointed as a
subdistributor of the Premium Authentication Service.

2.   RESELLER TERMS

          2.1.  Grant of Subdistributor License. Contego appoints Intelispan as
a subdistributor of the Premium Authentication Service for the Territory,
subject to the terms contained in this Agreement (the "Subdistributor License").
All customer agreements ("Customer Agreement") must comply with the
then-current Customer Agreement specified by Contego, in compliance with
requirements established by Contego. The current acceptable Customer Agreement
is specified in Attachment "A".

          2.2.  Territory. Intelispan may market, solicit and license the
Premium Authentication Service to prospective customers and customers
worldwide, without limitation (the "Territory").

          2.3.  Pricing. Intelispan must comply with the pricing terms specified
in Attachment "B".

          2.4.  Royalty. Intelispan shall pay to Contego, under the terms of
Section 2.5 below, a royalty of 60% of all amounts paid to Intelispan for the
Premium Authentication Service. The royalty shall be calculated based upon the
amount charged by Intelispan over its rate for any underlying services. For
example, if Intelispan sells a service that includes its exSPANd VPN, TradeSPAN
and the Premium Authentication Service, the royalty shall be paid only upon the
portion of the fee attributable to the Premium Authentication Service.
Intelispan shall not manipulate its fees to attribute less to the Premium
Authentication Service when it bundles its services. In case of a dispute, the
presumed reasonable amount shall be a pro rata percentage based upon
Intelispan's published rates for such services, which presumption may be
overcome by competent evidence.

          2.5.  Reporting and Payment Terms. No later than the thirtieth day
after each calendar quarter, Intelispan shall deliver to Contego a report
containing: (a) the name of each party with which Intelispan billed for the
Premium Authentication Service during the prior calendar quarter ("Customer");
(b) the amount of fees billed to and paid by the Customer for such period; and
(c) the amount of fees payable by Intelispan to Contego for such Customer. The
specified

                                     Page 1
<PAGE>   2
payment shall accompany the report. Intelispan must comply with the Customer
payment terms specified in the Customer Agreement.

          2.6.  Bad Accounts. Intelispan shall be credited with any payments
made to Contego for which Intelispan never receives Customer payment.

          2.7.  Audit rights. Contego shall have the right to examine books,
records and accounts of Intelispan, during normal business hours, to verify
Intelispan's reports regarding the amount of payments made under this
Agreement. If such examination discloses a shortfall in payment of more than
five percent (5%) for any calendar period, Intelispan shall reimburse Contego
for all reasonable expenses of such audit.

3.   INTELLECTUAL PROPERTY RIGHTS

          3.1.  Re-Branding and Attribution. Intelispan shall resell the Premium
Authentication Service under an Intelispan brand name, which Intelispan
currently anticipates will be "exSPANd-PKI" (the "Intelispan Mark"). Intelispan
may also distribute TD Client with the Intelispan Mark, provided that copyright
notices for the software are not modified and attribution is given to Contego
for developing the software.

          3.2.  License of Marks. Contego authorizes Intelispan to use the
"Contego" mark and logo ("Contego Marks"), at Intelispan's option, for

non-exclusive, non-transferable, non-assignable demonstration license (the
"Demo License") to operate, for internal marketing and demonstration purposes
only,the Premium Authentication Service including TD Client. Intelispan may use

software for the Premium Authentication Service contain copyrighted material,

human-readable form only for purposes of improving such software and/or to

Service. Contego maintains ownership of any such derivative works.

          3.6.  Export Issues. Use of Premium Authentication Service by the U.S.

other applicable U.S. Government organizations. Intelispan shall comply with

                                    ADDENDUM

This addendum ("Addendum") to the Distributor Agreement ("Distributor
Agreement") dated January 15, 1999 between Contego, LLC ("Contego") and
Intelispan, Inc. ("Intelispan") is effective this      day of          ,
1999.

A. Contego previously granted certain rights to Intelispan to Re-Brand the
   Premium Authentication Service as specified in Section 3.1 of the Distributor
   Agreement.

B. Intelispan now desires to make certain additional changes to the Contego
   product known as TD Client, both to use in reselling the Premium
   Authentication Service (branded by Intelispan as "exSPANd-PKI") and for use
   with Intelispan's own exSPANd VPN Service. For consistency in marketing, to
   save on costs, and to provide more transparency for customers that use both
   or change between exSPANd-PKI and exSPANd VPN, Intelispan desires to use the
   dialing capacity in TD Client as the dialer for the software offered with
   exSPANd VPN.

C. Contego does not desire to expend additional funds on the changes requested
   by Intelispan although it acknowledges that certain changes are necessary to
   improve the dialing capacity and other functionality of TD Client.

The parties therefore agree:

1. Contego licenses to Intelispan the right to modify the source code for the TD
   Client software (the "Revised Software") to make improvements in the dialer
   and in the software in general, whether to improve TD Client for use with the
   Premium Authentication Service or for use with Intelispan's exSPANd VPN
   Service, and to distribute the executable version of the Revised Software for
   use with the Premium Authentication Service and/or exSPANd VPN.

2. Contego licenses to Intelispan the right to use and re-brand the TD Client
   software without specific attribution to Contego.

3. Intelispan agrees to bear sole responsibility for payment of work to create
   the Revised Software. Except as specified herein, Intelispan agrees that
   Contego will retain all rights in the copyright and trade secrets to the
   Revised Software.
