faith, consider the financial impact on Vert of multiple or additional
instantiations and will take that factor, as well as Converge's legitimate, good

determination as to the number of instantiations.

(i.e., within their firewalls) for the sole and limited purpose of permitting
such End Users to interact, integrate and/or interact with any Converge
Marketplace, to include the use of services and products offered at any Converge
Marketplace (each, an "End User License"). Converge shall cause all members of

by End Users each quarter; provided, however, that during any quarter after the
first Year in which the number of instantiations of a Product component is less
than ten, Converge shall not have to report the number of instantiations of such
Product component during such quarter.

                  2.3.2 Other Sublicenses. Should Converge or the Converge
Subsidiaries desire to grant any other sublicenses with respect to the Products,
the parties shall in good faith discuss and consider whether and under what
conditions Converge and the Converge Subsidiaries would be permitted to grant
such other sublicenses, and any license fees and/or revenue share payments with
respect thereto.

14.11), and non-sublicensable right and license to internally use, load, store,
transmit, test, execute, distribute, in any medium or distribution technology
whatsoever, known or unknown, display, modify and have modified, and make and

Agreement and of the Object Code forms thereof, solely in connection with use of
the Products by Converge and the Converge Subsidiaries as permitted under this
Agreement. All such modifications and Derivative Works to the Source Code,
together with all Object Code forms thereof, shall be owned by Converge without
divesting Vert or its licensor's ownership of the underlying Source Code and the
Object Code forms thereof, and (b) Converge shall remain permitted to use the
underlying Object Code only as part of the Products licensed to Converge
hereunder. Converge shall have the right to engage third-party consultants that
are Converge-certified system integrators to perform such activities on behalf
of Converge; provided, however, that each such third-party consultant shall
agree in advance and in writing to be bound by obligations of nondisclosure and
nonuse no less stringent than those set forth in this Section 2.4.1 and in
Section 9. Subject to the foregoing sentence, Converge and the Converge
Subsidiaries shall not provide any other persons or entities with access to any
of the Source Code furnished to Converge under this Agreement.

                  2.4.2 Delivery of Source Code. In the event of a Converge PSA
Termination or a Converge PSA Conversion Election (as such terms are used in the
Professional Services Agreement), Vert shall deliver to Converge, within 30 days
thereafter, the Source Code for all Deployed Products and Deliverables in
Process (including, with respect to Trade Secret Modules, either the Source Code
for such Trade Secret Modules or their corresponding API Documentation) to the
extent such Source Code is owned by VNI or any of the VNI Subsidiaries.
Thereafter, Vert shall deliver to Converge the Source Code for all Deployed
Product Upgrades (including, with respect to Trade Secret Modules, either the
Source Code for


                                       9

commencing on the Effective Date, to the extent such Source Code is owned by VNI
or any of the VNI Subsidiaries. Each such delivery of the Source Code for

of Default underlying the Converge PSA Termination Event or the Converge PSA
Conversion Election, the matter shall be resolved as expeditiously as possible
in accordance with the dispute resolution provisions of the Professional
Services Agreement and no delivery of Source Code hereunder shall occur until
such time as the matter is resolved.

                  2.4.3 Source Code for Third-Party Products. With respect to
Products that are licensed to VNI or the VNI Subsidiaries by third parties, Vert
will reasonably cooperate with Converge to arrange for delivery of the Source
Code for such Products to Converge in accordance with the provisions of Section
2.4.2.

                  2.4.4 Loss of Rights to Source Code. In the event of a Vert
Remedy Election all rights of Converge under Section 2.4.1 to use, load, store,
transmit, execute, distribute internally, display, modify and have modified, and
make and have made derivative works of, any Source Code delivered to Converge
under Section 2.4.2, and to receive further Source Code for Deployed Products,
Deployed Product Upgrades and Deliverables in Process under Section 2.4.2, shall
automatically cease. Furthermore, in the event of a Vert Remedy Election,
Converge shall erase, destroy or return to Vert all Source Code delivered to
Converge under Section 2.4.2, together with all copies, modifications and
derivative works thereof, and, upon Vert's written request, shall certify its
compliance with this Section 2.4.4 to Vert in writing.

            2.5 Limitation on Worldwide Rights. Notwithstanding any provision in
this Agreement or the Professional Services Agreement to the contrary, no right
or license is granted by Vert to Converge or any of the Converge Subsidiaries
to: (a) use, copy, display, perform or transmit the Products listed in Exhibit E
as "Japan-Restricted Community Products" or "Japan-Restricted Content Products"
(the "Japan-Restricted Community and Content Products") in Japan in connection
with the development, marketing, implementation, operation or provision of any
Internet-based business-to-business vertical trade community that is based on an
industry segment and combines content, community interaction and the ability to
conduct business transactions on-line, including sales of products and services
to businesses, and that has a URL that ends in the top level domain
"________________.co.jp" (a "Japanese Site"); (b) adapt or translate the
Japan-Restricted Community and Content Products into Japanese in connection with
the development, marketing, implementation, operation or provision of a Japanese
Site; or (c) use a Japanese translation of the software code enabling the
Japan-Restricted Community and Content Products in Japan. Notwithstanding the
foregoing, neither Converge nor any Converge Subsidiary shall be deemed to be
using, reproducing, displaying, performing or transmitting the software code
enabling the Japan-Restricted Community and Content Products, or a Japanese
translation thereof, in Japan if a Converge Web Site containing software code
enabling the Japan-Restricted Community and Content Products, or a Japanese
translation thereof, is hosted outside Japan and is accessed by a third party
inside Japan.

            2.6 Limited Exclusivity. Neither VNI nor any of its Affiliates shall
license, sell, assign or otherwise transfer Trade Products and other Vert-Owned
Deliverables to any person, entity or licensee to create, maintain, enhance or
operate, or be accessed or used via or in connection with, or be marketed or
offered as a service on, any Public Marketplace principally serving the High
Technology Industry, other than a Converge Marketplace, without the prior
written consent of Converge; provided, however, that neither VNI nor any of its
Affiliates shall be deemed to violate the foregoing restriction by operating a
VNI "Industry Marketplace" that has and remains based on substantially the same
elements of its business model as exist on the Effective Date in the VNI
"E-Commerce Centers." The restriction set forth in this Section 2.6 shall be
effective from the Effective Date until the soonest to occur of (a) the date
immediately preceding the Limited Exclusivity Expiration Date (defined below),
(b) the Vert Remedy Election Date or (c) the date immediately preceding the
first anniversary of the date that VNS exercises its right to terminate the
Professional Services Agreement following an "Event of Default" by Converge
under the Professional Services Agreement. For purposes of this Section 2.6
only, the application known as "AutoMatch" shall be deemed a "Trade Product." As
used herein, the term "Limited Exclusivity Expiration Date" means the date
immediately preceding the third anniversary of the Effective Date unless
Converge validly exercises its option set forth in the following sentence, in
which case the "Limited Exclusivity Expiration Date" shall be the date
immediately preceding the fourth anniversary of the Effective Date. Converge
shall have the option to extend the Limited Exclusivity Expiration Date by one
year from the date immediately preceding the third anniversary of the Effective
Date to the date immediately preceding the fourth anniversary of the Effective
Date, exercisable by Converge (i) delivering written notice of exercise to Vert
at least 60 days prior to the date immediately preceding the third anniversary
of the Effective Date and (ii) transferring to VNS $5,000,000 in immediately
available funds (to an account or accounts designated by VNS) on the second
Business Day of the first quarter of Year 4.

            2.7 Exclusive Use of Products. The following shall be effective from
the Effective Date until the sooner to occur of (a) the date immediately
preceding the third anniversary of the Effective Date, (b) the Vert Remedy
Election Date or (c) the Converge Remedy Election Date: Converge will use best
efforts to implement, use and deploy Trade Products in connection with the
creation, maintenance, enhancement or operation of any Converge Marketplace, to
the exclusion of any alternative third party software solution, provided that
the Trade Products, in comparison with such third party software solution, (i)
provide equal or superior features, functionality, usability and performance in
all material respects and (ii) cost a reasonably equivalent or lesser amount to
implement and maintain. The parties will work in good faith to identify and
implement pilot releases of Products that are mutually beneficial.

            2.8 Use of Documentation. Subject to the other terms of this
Agreement, Converge and the Converge Subsidiaries may access and use the
Documentation, including by private-labeling said Documentation and by
excerpting and/or modifying portions thereof in a manner that is not confusing
or misleading, solely in connection with their use (including ancillary uses,
such as training, marketing and promotion, etc.) of the Products as permitted
under this Agreement.

            2.9 Copies. Converge and the Converge Subsidiaries shall be
permitted to make a reasonable number of copies of the Products and the
Documentation for the purposes


                                       11
<PAGE>

allowed by this Agreement, which copies shall be stored at locations under the
control of Converge or at the facilities of Converge's third party hosting and
disaster recovery service provider(s). Converge agrees to maintain, and shall
require the Converge Subsidiaries to maintain, accurate and complete written or
electronic records of the number and location of all copies or partial copies of
the Products in their possession or control, including all back-up and archival
copies.

            2.10 Third-Party Hosting. Converge and the Converge Subsidiaries
shall have the right to sublicense one or more third-party hosting entities to
reproduce, install, publicly perform, publicly display and host any of the
Products, in Object Code form, on such third party's servers, subject to the
terms of this Agreement. Such sublicenses shall be granted pursuant to written
agreements that authorize such third-party hosting entities to host, operate
and/or maintain such Products solely on behalf of Converge and the Converge
Subsidiaries as permitted hereunder.

            2.11 Audit Rights. Each party (the "Auditing Party") shall have the
right reasonably to audit, at its expense, the compliance with this Agreement by
the other party (the "Audited Party") and its Subsidiaries (together with the
Audited Party, the "Auditees"), provided that such audit(s) shall be conducted
during normal business hours and in such a manner as not to unreasonably
interfere with the operations of the Auditees. Any such audit will be conducted
by accountants from a nationally recognized public accounting firm chosen and
engaged by the Auditing Party. If any such audit discloses substantial
unlicensed use of the Products, the Audited Party shall reimburse the Auditing
Party for the reasonable fees and other amounts payable by the Auditing Party to
the public accounting firm that conducts the audit. The Auditing Party shall use
the information obtained or observed in the audit solely for the purposes of (a)
determining whether the Auditees have sufficient license rights for their use of
the Products and are otherwise complying with the terms and conditions of this
Agreement respecting such use, and (b) enforcing its rights under this Agreement
and any applicable laws. All such information shall be treated as Confidential
Information of the Audited Party for purposes of this Agreement; provided,
however, that the Auditing Party may use such information as permitted under
clause (b) of the foregoing sentence. Each party shall require each of its
Subsidiaries to permit the other party to conduct the audits authorized
hereunder.

            2.12 Notice to Users. Converge shall, and shall require the Converge
Subsidiaries to, use reasonable efforts to make all users of the Products
hereunder (including, without limitation, users of any Converge Marketplace that
are permitted to access or use the Products) aware that the Products (a) may
only be used subject to the terms and conditions contained in this Agreement and
the corresponding Documentation for such Products and (b) may not be copied,
transferred or otherwise used in violation of such terms and conditions.

            2.13 No Implied Licenses. No license or other rights to the Products
or the Documentation are granted, by implication or otherwise, except as
expressly set forth in this Agreement.

                  2.14.1 During the Product Term. Except as set forth in Section
2.14.2 or Section 2.14.3, Vert will provide Converge and the Converge
Subsidiaries with Maintenance & Support Services for all Products (excluding
Vert-Owned Deliverables) during the Product Term, and the cost of such services
is included in the amounts paid pursuant to Section 3.1.

                  2.14.2 Post-Product Term - No Remedy Election. In the event
the Product Term ends other than due to a Converge Remedy Election or a Vert
Remedy Election, Converge may purchase continued Maintenance & Support Services
for any individual Products (excluding Vert-Owned Deliverables) on a
year-by-year basis by paying Vert the then-standard fees for maintenance and
support for such Products that VNI or the applicable VNI Subsidiaries charge to
similarly situated licensees. In such circumstance, the Maintenance & Support
Services provided by Vert after the Product Term shall not include the right to
receive any Enhancements, unless such Enhancements are made generally available
as part Maintenance & Support Services provided to similarly situated licensees
of the Products in question.

                  2.14.3 Post-Product Term - Vert Remedy Election. In the event
the Product Term ends due to a Vert Remedy Election, Converge shall be entitled
to continued Maintenance & Support Services for any Deployed Products at no
additional cost for the remainder of the initial three-year period commencing on
the Effective Date. Thereafter, Converge may purchase continued Maintenance &
Support Services for any Deployed Products on a year-by-year basis by paying
Vert the then-standard fees for maintenance and support for such Deployed
Products that VNI or the applicable VNI Subsidiaries charge to similarly
situated licensees. In either of the foregoing circumstances, the Maintenance &
Support Services provided by Vert after the Product Term shall not include the
right to receive any Enhancements, unless such Enhancements are made generally
available as part Maintenance & Support Services provided to similarly situated
licensees of the Deployed Products in question.

                  2.14.4 Post-Product Term - Converge Remedy Election. In the
event the Product Term ends due to a Converge Remedy Election, Converge may
purchase continued Maintenance & Support Services for any Deployed Products on a
year-by-year basis by paying Vert the then-standard fees for maintenance and
support for such Deployed Products that VNI or the applicable VNI Subsidiaries
charge to similarly situated licensees. In such circumstance, the Maintenance &
Support Services provided by Vert for the remainder of the initial three-year
period following the end of the Product Term shall include the right to receive
Upgrades to Deployed Products, but not other Enhancements, unless such other
Enhancements are made generally available as part of the Maintenance & Support
Services provided to similarly situated licensees of the Deployed Products in
question. Thereafter, the Maintenance & Support Services shall not include the
right to receive any Enhancements, unless such other Enhancements are made
generally available as part Maintenance & Support Services provided to similarly
situated licensees of the Deployed Products in question.

            2.15 Delivery and Acceptance. Vert will transfer the Products and
all Documentation by remote telecommunications from the Vert place of business,
to a Converge computer located in the State of California. If the Products and
Documentation cannot be delivered via remote telecommunications to a Converge
computer located in the State of


                                       13
<PAGE>

California, the Products and Documentation will be installed by Vert on the
Converge computer located in the State of California. Converge will not obtain
title or possession of any tangible personal property, including any storage
media, as a result of the delivery of any Product under this Agreement. All
Products and Documentation existing as of the Effective Date shall be delivered
to Converge within 30 days following the Effective Date. Other Products shall be
delivered to Converge (a) promptly following the date on which they are
available as a beta or other early release version (provided, however, that Vert
shall not be obligated to provide Maintenance & Support Services for such
pre-release versions, and such pre-release versions shall not be used in a
production environment without Vert consent) and (b) promptly following the date
on which they become generally available. Without exception, all Products
including, but not limited to, Updates and Enhancements shall be delivered to
Converge as they become generally available and in accordance with the delivery
procedure outlined in this Section 2.15. Each Product, Update and Enhancement
will be deemed accepted by Converge upon Converge's receipt of the complete
delivery to the Converge computer located in the State of California thereof.

            2.16 Product List. Vert represents that Exhibit A, in the form
initially attached to this Agreement, is a reasonably complete and correct list
of all Products existing as of the Effective Date. Vert agrees to promptly amend
and update Exhibit A, from time to time, to reflect Future Products.

            2.17 Promotion Efforts and Responsibilities. The parties will
participate in mutually acceptable joint promotional activities that may include
those of the type set forth in Exhibit D.

the Effective Date and thereafter during the Product Term, Vert shall place a
Converge Link from each of VNI's "Industry Marketplaces" in the High Technology
Industry to any and all Converge Web Sites in a mutually agreed upon manner.
Converge hereby grants Vert a non-exclusive, non-transferable, royalty-free
right and license to (a) link to the Converge Web Sites through Converge Links
as described in this Section 2.18.1 and (b) use a Converge Mark(s) in connection
with such Link. Vert agrees to use the Converge Mark(s) in accordance with this
Agreement, with the trademark and usage guidelines of Converge in Exhibit F
hereto, and with good trademark practices, including, but not limited to,
protecting the value of the goodwill residing in such intellectual property.

                  2.18.2 Vert Links and Vert Marks. Within 30 days after the
Effective Date and thereafter during the Product Term, Converge shall place a
Vert Link from each Converge Web Site within the Converge Marketplace to any and
all of VNI's "Industry Marketplaces" in the High Technology Industry. Vert
hereby grants Converge a non-exclusive, non-transferable, royalty-free right and
license to (a) link to VNI's "Industry Marketplaces" in the High Technology
Industry through Vert Links as described in this Section 2.18.2 and (b) use a
Vert Mark in connection with (i) such Link and (ii) the promotion of certain

                                       14
<PAGE>

trademark practices, including, but not limited to, protecting the value of the
goodwill residing in such intellectual property.

                  2.18.3 Integration. The parties will explore and pursue
further integration opportunities to link the Converge Marketplace with VNI's
"Industry Marketplaces" in the High Tech Industry.

                  2.18.4 Ownership of Vert Marks. Vert owns all right, title and
interest in and to the Vert Marks and all Intellectual Property Rights and
goodwill (including, but not limited to, goodwill accruing during the term of
this Agreement) associated therewith. Except for the express rights granted to
Converge under this Agreement, Converge acknowledges and agrees that the
Intellectual Property owned, acquired or developed by Vert (including all
Intellectual Property Rights associated therewith), including, but not limited
to the Vert Marks, is and shall remain the sole property of Vert and nothing in
this Agreement shall confer in Converge any right of ownership or license rights
in Vert's Intellectual Property (including all Intellectual Property Rights
associated therewith).

                  2.18.5 Ownership of Converge Marks. Converge owns all right,
title and interest in and to the Converge Marks and all Intellectual Property
Rights and goodwill (including, but not limited to, goodwill accruing during the
term of this Agreement) associated therewith. Except for the express rights
granted to Vert under this Agreement, VNI acknowledges and agrees that the
Intellectual Property owned, acquired or developed by Converge (including all
Intellectual Property Rights associated therewith), including, but not limited
to the Converge Marks, is and shall remain the sole property of Converge and
nothing in this Agreement shall confer in Vert any right of ownership or license
rights in Converge's Intellectual Property (including all Intellectual Property
Rights associated therewith).

            2.19 Marketplace Protection Measures. Unless otherwise agreed upon
by the parties in writing, Converge shall implement and operate the Marketplace
Protection Measures for the Converge Web Site at www.converge.com within four
months following the Effective Date. With respect to any other Converge
Marketplace utilizing any Trading Functionality, unless otherwise agreed upon by
the parties in writing, Converge shall implement the applicable Marketplace
Protection Measures within three months following the date on which such Trading
Functionality is first utilized on such other Converge Marketplace in a
production environment. For so long as any Converge Marketplace continues to
utilize any Trading Functionality, Converge agrees to continue implementing and
operating all applicable Marketplace Protection Measures in all material
respects with respect to such Converge Marketplace.

      3. Fees and Payments.

            3.1 Fees for Products.

                  3.1.1 General. The fees for the license rights granted to the

VNS in accordance with the provisions of Exhibit B.


                                       15
<PAGE>

                  3.1.2 Converge Remedy Election. The only event that shall
relieve Converge of its obligation to pay the fees set forth in Exhibit B shall
be a Converge Remedy Election, which event shall relieve Converge of its
obligation to pay those fees set forth in Exhibit B that first become due and
payable after the Converge Remedy Election Date. For the sake of clarity,
Converge shall remain obligated to pay all fees set forth in Exhibit B that
become due on or before the Converge Remedy Election Date, but that have not
been paid by Converge on or before the Converge Remedy Election Date.

                  3.1.3 Vert Remedy Election. Notwithstanding the occurrence of
a Vert Remedy Election, Converge shall remain obligated to pay the full amount
of all fees set forth in Exhibit B, whether such fees become due before, on or
after the Vert Remedy Election Date.

            3.2 On-Site Maintenance. Converge shall pay Vert's then-standard
charges for any on-site Maintenance & Support Services provided by Vert under
this Agreement. The amounts payable under this Section 3.2 shall be in addition
to the fees payable by Converge under Section 3.1.

            3.3 Commissions Due to Converge. Commissions due to Converge with
respect to the joint promotional activities conducted under Exhibit D shall be
paid by VNS as set forth therein.

            3.4 Payments. All payments will be made in U.S. dollars, without
setoff or deduction. Amounts due under Section 3.2 will be invoiced to Converge
by VNS. Payment of such invoiced amounts shall be due within 30 days of
Converge's receipt of invoice. All fees and other payments not paid when due
shall be subject to late charges of the lesser of (a) 1.5% per month of the
overdue amount or (b) the maximum permitted under applicable law.

            3.5 Taxes.

                  3.5.1 Generally. The fees and other payments specified in this
Agreement are exclusive of any sales, use and other taxes on consumption of
goods and services ("Sales Taxes"), however designated or levied, based on this
Agreement, the delivery of the Products or services under this Agreement, or
Converge's or the Converge Subsidiaries' use thereof. In those jurisdictions in
which VNS determines it is required to register, collect and remit Sales Taxes,
VNS will separately invoice Converge for such Sales Taxes (which invoices shall
be payable by Converge as set forth in Section 3.4), collect such Sales Taxes
from Converge and remit such Sales Taxes to the proper taxing authority. In
those jurisdictions in which VNS has determined that it does not have a
collection responsibility, Converge will be required to self-assess and remit
any Sales Taxes due on the purchase of taxable property and services acquired
under this Agreement. Converge will retain ultimate responsibility and liability
for remitting any Sales Taxes due on the purchase of any property and/or
services acquired under this Agreement, including, without limitation, any
interest, penalties or additions attributable to or imposed on or with respect
to any such assessment excluding any taxes imposed upon the net income of either
party).

                  3.5.2 Certain Sales Taxes. The parties will cooperate and use
their commercially reasonable efforts to minimize or avoid, to the maximum
extent allowed by law,


                                       16
<PAGE>

the obligation to pay any Sales Taxes that may be levied on payments made under
this Agreement or otherwise are chargeable to or against VNS by any applicable
government authority with respect to the Services and the Deliverables. To that
end, the parties will conduct transactions using an electronic commerce approach
under which Vert will provide all Services (where applicable) and all
Deliverables to Converge using an electronic medium of delivery, electronically
via the Internet, by "drop and load" to an Converge computer from a CD-ROM that
is in the possession and control of Vert Personnel at all times, or in any other
mutually agreeable intangible form or by such other means as is mutually agreed
upon by the parties. Additionally, the parties will electronically transmit and
receive SOWs, invoices and other applicable documentation. Each party, at its
own expense, will provide and maintain the equipment, software, services and
testing necessary for it to transmit and receive such documentation. Any amount
of Sales Tax that legally could have been avoided but for the acts or omissions
of a party will be payable by that party. Sales Taxes that may not be avoided
will be payable (a) one-half by Converge and one-half by VNS if due to a US
federal, state or local taxing authority and (b) by Converge if due to a non-US
taxing authority. Taxes chargeable against the income or gross receipts of VNS
shall be paid by VNS. Taxes chargeable against the income or gross receipts of
Converge shall be paid by Converge.

            3.6 Tax Withholding. If laws, rules or regulations require
withholding of any taxes imposed upon amounts payable to a party hereunder, the
other party shall make such withholding payments as required and subtract such
withholding payments from the amounts payable to such party. The other party
shall submit reasonable proof of payment of the withholding taxes to such party
within 30 days after obtaining such proof. The parties agree to fully cooperate
with each other, including, without limitation, in the filing of appropriate
certificates of tax exemption, to ensure that any withholding payments required
to be made by the other party are reduced or avoided to the fullest extent
permitted by law. Converge shall be deemed to be the sole payor of payments owed
to VNS under this Agreement and shall not have the right to substitute any
domestic or foreign affiliate for that purpose, and if Converge reincorporates
or otherwise reorganizes as a foreign person that would thereupon cause payments
hereunder to VNS to become subject to withholding, then Converge shall comply
with applicable laws to the extent required and shall gross up the payments
otherwise owed to VNS so that VNS receives, net of withholding taxes, the
amounts VNS would have received if Converge had not substituted a foreign person
or had remained a domestic person.

            3.7 Most Favored Nation. If at any time following the Product Term,
Converge purchases software product(s) and/or maintenance & support services
(including, but not limited to, Maintenance & Support Services purchased
pursuant to Section 2.4), the provisions of this Section 3.7 shall apply.
Notwithstanding anything to the contrary herein, all fees, charges and rates
charged or invoiced by Vert in connection with such software products and
maintenance & support services shall be as low as or lower than the fees,
charges and rates charged or invoiced at the relevant time by Vert to any of its
other similarly situated customers for software products or for maintenance &
support services of the same or a substantially similar nature.

      4. Warranty.

            4.1 Scope of Warranty. Vert warrants that for the shorter of six
months after receipt by Converge of each Product (which for purposes of this
Section 4.1, shall include Enhancements to existing Products, but not Updates to
such Products) or 90 days after the date of deployment of the Product by
Converge in a production environment (the "Warranty Period") such Product, as
delivered by Vert to Converge, will be free from Errors, provided that such
Product has not been modified by Converge or any third party. In the event that
a Problem occurs with respect to a Product, which Problem is attributable to an
Error, and provided that Converge reports such Problem to Vert within the
Warranty Period, Vert, as its sole obligation and Converge's sole and exclusive
remedy, shall respond to such Problem and correct any associated Errors, subject
to and in accordance with the provisions of Exhibit C. The warranty set forth in
this Section 4.1 shall not apply with respect to Vert-Owned Deliverables, which
shall be warranted, if at all, as set forth in the Professional Services
Agreement, nor shall the warranty set forth in this Section 4.1 apply to any
beta or other early release versions of Products provided to Converge under
Section 2.15.

            4.2 Disclaimer. WITH THE EXCEPTION OF THE EXPRESS WARRANTY PROVIDED
IN SECTION 4.1 AND THE INDEMNITY PROVIDED IN SECTION 8, VNI AND ALL AFFILIATES
OF VNI SPECIFICALLY DISCLAIM ANY AND ALL WARRANTIES, EXPRESS OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS
FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF THIRD PARTY RIGHTS RELATING TO
THE PRODUCTS AND ANY SERVICES FURNISHED OR OTHERWISE PROVIDED HEREUNDER, IF ANY.
IN ADDITION, ALL BETA OR OTHER EARLY RELEASE VERSIONS OF PRODUCTS PROVIDED TO
CONVERGE UNDER SECTION 2.15 ARE PROVIDED BY VNI AND ALL AFFILIATES OF VNI "AS
IS" AND "WITH ALL FAULTS" AND VNI AND ALL AFFILIATTES OF VNI DISCLAIM ANY AND
ALL WARRANTIES, EXPRESS OR IMPLIED, WITH RESPECT THERETO.

            5. Proprietary Rights. The Products and the Documentation are
protected by applicable copyright and other intellectual property laws and
international treaty provisions. As between Vert and Converge, but subject to
any contrary provisions in the Professional Services Agreement with respect to
Deliverables (as defined therein) provided thereunder, and to the rights and
licenses granted to Converge hereunder, Vert and its licensors own all right,
title and interest (including but not limited to all copyrights, patents,
trademarks, trade names and trade secrets and other proprietary rights) in and
to the Products and the Documentation. Converge agrees to reproduce all
copyright, trademark and other proprietary notices contained on or in the
Products or the Documentation, as delivered to Converge, on all copies thereof,
and Converge further agrees not to remove or obscure any such notices. Except as
expressly set forth in this Agreement or the Professional Services Agreement,
Converge acknowledges and agrees that Vert has no obligation to deliver Source
Code under the terms of this Agreement, or to grant Converge any license to use
the Source Code form of the Products. Except as expressly permitted hereunder,
the Products are not to be licensed, sold, rented, leased or otherwise
transferred by Converge. Converge agrees not to (a) decompile, reverse engineer
or disassemble or otherwise attempt to reconstruct or discover any Source Code
or underlying algorithms of the Products that are provided solely in Object Code
form or (b) separate or disassociate any


                                       18
<PAGE>

component parts of the Products (it being understood that this restriction shall
not restrict Converge from separating or disassociating separately identified
modules from Products containing them). Except as expressly set forth in this
Agreement and in the Professional Services Agreement, Converge shall not modify
or change the Products or the Documentation (except to configure the Products by
means of their user-enabled features) in any manner, nor may Converge create any
derivative works of the Products or the Documentation. The provisions of this
Section 5 shall apply equally to the Converge Subsidiaries and Converge shall
ensure that any Converge Subsidiaries provided with access to or use of the
Products are bound thereby.

      6. Source Code Escrow.

            6.1 Escrow Materials. Within 30 days following the Effective Date,
the parties shall put in place a mutually acceptable escrow agreement pursuant
to which Vert shall place in escrow with Fort Knox or other escrow agent
mutually agreeable to the parties (the "Escrow Agent") true and complete copies
of the Source Code for the Products (including, with respect to Trade Secret
Modules, either the Source Code for such Trade Secret Modules or their
corresponding API Documentation, with the understanding that Vert may remove the
Source Code for any Trade Secret Module from escrow at the time it places its
corresponding API Documentation into escrow) owned by VNI or any of the VNI
Subsidiaries and existing as of the Effective Date. Promptly following the date
on which any other Product, Update or Enhancement owned by VNI or any the VNI
Subsidiaries becomes generally available, or any Vert-Owned Deliverable is
provided to Converge under the Professional Services Agreement, but in any event
at least once per calendar quarter, Vert shall deliver to the Escrow Agent the
Source Code for such other Products, Updates, Enhancements and Vert-Owned
Deliverables (including, with respect to Trade Secret Modules, either the Source
Code for such Trade Secret Modules or their corresponding API Documentation,
with the understanding that Vert may remove the Source Code for any Trade Secret
Module from escrow at the time it places its corresponding API Documentation
into escrow). All of the foregoing materials delivered by Vert to the Escrow
Agent are referred to herein as the "Escrow Materials."

            6.2 Release Events. For purposes of this Agreement, the following
shall be deemed "Release Events": (a) VNI becomes insolvent, files for
bankruptcy or is subjected to involuntary bankruptcy proceedings that are not
dismissed within 60 days, or makes a general assignment for the benefit of its
creditors; (b) Vert ceases to offer any maintenance services for a Product; or
(c) Converge makes a Priority Remedy Election. Notwithstanding anything to the
contrary herein, if the claimed Release Event is under clause (b) or clause (c)
above, only the Escrow Materials for the Product that is the subject of the
Release Event, together with all associated Updates and Enhancements, shall be
subject to release to Converge hereunder.

            6.3 Delivery of Escrow Materials. Should Converge desire to obtain
any Escrow Materials due to the occurrence of a Release Event, Converge shall
provide Vert and the Escrow Agent with written notice thereof. The Escrow Agent
shall be instructed to promptly provide a copy of such notice to Vert. Unless
the Escrow Agent receives written notice from Vert contesting the occurrence of
such Release Event within 15 days after Vert receives such copy of Converge's
notice (48 hours in the event the Release Event is a Priority Remedy Election by
Converge), the Escrow Agent shall be instructed to deliver the relevant Escrow


                                       19
<PAGE>

Materials to Converge forthwith. In the event Vert contests the occurrence of
the Release Event, the matter shall be resolved as expeditiously as possible in
accordance with the dispute resolution provisions of the Escrow Agreement and
the Escrow Materials shall remain in escrow until such time as the matter is
resolved.

            6.4 Fees of Escrow Agent. Converge shall pay all fees and other
amounts payable to the Escrow Agent under the Escrow Agreement.

            6.5 Escrow of Third-Party Products. With respect to Products that
are licensed to VNI or the VNI Subsidiaries by third parties, Vert will
reasonably cooperate with Converge to arrange for true and complete copies of
the Source Code for such Products to be deposited with the Escrow Agent and to
be held in escrow in accordance with the provisions of this Section 6 and the
Escrow Agreement.

            6.6 Loss of Rights to Source Code. Should Vert cure a Priority Event
of Default by effectuating a Cataclysmic Event Cure with respect to the
Cataclysmic Event giving rise thereto prior to a Priority Remedy Election, then:
(i) the rights of Converge under Section 2.4.1 to use, load, store, transmit,
execute, distribute internally, display, modify and have modified, and make and
have made derivative works of, the Source Code delivered to Converge under this
Section 6 by reason of such Priority Event of Default shall automatically cease;
(ii) Converge shall erase, destroy or return to the Escrow Agent all such Source
Code, together with all copies, modifications and derivative works thereof; and
(iii) upon Vert' written request, shall certify its compliance with this Section
6.6 to Vert in writing.

      7. Limitation of Liability.

            7.1 Disclaimer of Certain Damages. TO THE MAXIMUM EXTENT PERMITTED
BY LAW, IN NO EVENT SHALL EITHER PARTY BE LIABLE OR OBLIGATED IN ANY MANNER FOR

OPERATE WITHOUT ERROR OR INTERRUPTION AND VERT SHALL NOT BE RESPONSIBLE FOR ANY
DAMAGES ASSOCIATED WITH LOSS OF DATA OR INTERRUPTION OR LOSS OF USE OF PRODUCTS
RESULTING THEREFROM.

            7.3 Maximum Aggregate Liability. TO THE MAXIMUM EXTENT PERMITTED BY
LAW, THE MAXIMUM LIABILITY OF EACH PARTY TO THE OTHER OR TO ANY THIRD PARTY FOR

      8. Indemnification.

            8.1 By Vert.

                  8.1.1 Vert Indemnity. Vert agrees to defend and hold Converge
and its officers, directors, employees and agents harmless from and against any
suit, claim or action by any unaffiliated third party (a "Converge Claim")
alleging that any of the Products, when used within the scope of this Agreement
and its corresponding Documentation, infringe upon or misappropriate any U.S.
patent, European Union Office patent, patent of a country in the European Union,
copyright or trade secret of a third party. Vert further agrees to indemnify
Converge and its officers, directors, employees and agents for any damages,
costs, liabilities, expenses (including, without limitation, attorneys fees) and
settlement amounts payable to unaffiliated third parties in connection with such
Converge Claims. The foregoing obligations shall not extend to any Converge
Claims arising out of or related to (a) a modification of the Products by or at
the direction of anyone other than Vert, to the extent that such modification is
the cause of such infringement; (b) a combination of the Products with any third
party software or equipment neither recommended, approved or authorized by Vert
in writing, whether in any Documentation for the Product or otherwise, to the
extent that such combination is the cause of such infringement; (c) portions of
the Products based on unique specifications or requirements provided or selected
by Converge, to the extent that such portion is the cause of such infringement;
or (d) solely with respect to infringement claims concerning U.S. patent,
European Union Office patent or patent of a country in the European Union, any
infringement claims to the extent based on or arising out of Future Products.
For the purposes of this Section 8.1, the term "Products" shall exclude the
Vert-Owned Deliverables.

                  8.1.2 Converge Obligation. Vert's obligations to defend,
indemnify and hold Converge harmless are subject to Converge (a) giving Vert
prompt written notice of any such Converge Claim; (b) giving Vert sole control
over the defense and settlement of any such Converge Claim; (c) providing full
cooperation for the defense of any such Converge Claim, at Vert's expense; and
(d) not entering into any settlement or compromise of any such Converge Claim
without Vert's prior written approval.

                  8.1.3 Mitigation. If Converge is enjoined or is reasonably
likely to be enjoined from using any Products as permitted hereunder, Vert will,
at its own expense, exercise the first of the following remedies that is
practicable: (i) obtain for Converge the right to continue to use, sell and
license the Products as permitted under this Agreement; (ii) modify Products so
they are non-infringing and functionally equivalent in all material respects to
the infringing Products; or (iii) replace the Products, or other affected
Products, with non-infringing ones that are functionally equivalent in all
material respects to the infringing Services and Deliverables; provided,
however, that Vert may seek to provide the remedies in (ii) or (iii) above prior
to seeking to provide the remedy in (i) above only if such decision would not
have a significant adverse impact on Converge's ability to provide uninterrupted
products or services to its customers; provided, however, that with respect to
infringement claims concerning U.S. patents, European Union Office patents or
patents of a country in the European Union, Vert shall in no event be required
to incur costs or expenses in excess of $1,000,000, in the aggregate and
regardless of the number of claims involved, in performing its obligations under
this Section 8.1.3. If all of the remedies set forth in the preceding sentence
are neither technically feasible


                                       22
<PAGE>

nor available on commercially reasonable terms, then Vert may, or if the
following remedy is requested by Converge, then Vert shall, require the return
of the affected Deliverables and pay to Converge the list price charged by Vert
for such Products.

                  8.1.4 Sole Remedy. IF A CLAIM OR CAUSE OF ACTION RELATING TO
THE INFRINGEMENT OR MISAPPROPRIATION OF ANY PATENT, COPYRIGHT, TRADE SECRET OR
OTHER INTELLECTUAL PROPERTY RIGHT IS ATTRIBUTABLE TO A PRODUCT (BUT EXCLUDING
ANY VERT-OWNED DELIVERABLES), THE REMEDIES SET FORTH IN THIS SECTION 8, TO THE
EXCLUSION OF THE REMEDIES SET FORTH IN THE PROFESSIONAL SERVICES AGREEMENT,
SHALL CONSTITUTE THE SOLE AND EXCLUSIVE REMEDIES AVAILABLE TO CONVERGE FOR SUCH
CLAIM OR CAUSE OF ACTION. IF A CLAIM OR CAUSE OF ACTION RELATING TO THE
INFRINGEMENT OR MISAPPROPRIATION OF ANY PATENT, COPYRIGHT, TRADE SECRET OR OTHER
INTELLECTUAL PROPERTY RIGHT IS ATTRIBUTABLE TO A DELIVERABLE OR ANY SERVICES
PROVIDED UNDER THE PROFESSIONAL SERVICE AGREEMENT (EXCLUDING ANY UNDERLYING
PRODUCTS (OTHER THAN VERT-OWNED DELIVERABLES) INCLUDED IN SUCH DELIVERABLES),
THE REMEDIES SET FORTH IN THE PROFESSIONAL SERVICES AGREEMENT, TO THE EXCLUSION
OF THE REMEDIES SET FORTH IN THIS AGREEMENT, SHALL CONSTITUTE THE SOLE AND
EXCLUSIVE REMEDIES AVAILABLE TO CONVERGE FOR SUCH CLAIM OR CAUSE OF ACTION.

            8.2 By Converge.

                  8.2.1 Converge Indemnity. Converge agrees to defend and hold
Vert and its officers, directors, employees and agents harmless from and against
any suit, claim or action by any unaffiliated third party (a "Vert Claim")
relating to (a) the operation of and/or business conducted on or through any
Converge Marketplace, except to the extent that the occurrence giving rise to
such Vert Claim is a suit, claim or action by any unaffiliated third party
alleging that any Product, when used within the scope of the rights granted to
Converge under this Agreement, infringes upon or misappropriates any U.S. or
foreign patent copyright, trade secret or other intellectual property rights of
a third party; (b) the use of any Product outside the scope the rights granted
to Converge under this Agreement; or (c) any claim associated with any Converge
product or service to the extent not based on Products or service provided by
Vert hereunder. Converge further agrees to indemnify Vert and its officers,
directors, employees and agents for any damages, costs, liabilities, expenses
(including, without limitation, attorneys fees) and settlement amounts payable
to unaffiliated third parties in connection with such Vert Claims.

                  8.2.2 Vert Obligation. Converge's obligations to defend,
indemnify and hold harmless Vert are subject to Vert (a) giving Converge prompt
written notice of any such Vert Claim; (b) giving Converge sole control over the
defense and settlement of any such Vert Claim; (c) providing full cooperation
for the defense of any such Vert Claim, at Converge's expense; and (d) not
entering into any settlement or compromise of any such Vert Claim without
Converge's prior written approval.

      9. Confidential Information.

            9.1 Definition of Confidential Information. "Confidential
Information" as used in this Agreement shall mean any and all proprietary or
non-public information of a party (including, without limitation, any Source
Code furnished by or to Converge hereunder) whether in oral, written or other
tangible form that the party disclosing the information (the "Discloser")
designates as being confidential or which, under the circumstances surrounding
disclosure, the receiving party (the "Recipient") knows or has reason to know
should be treated as confidential.

            9.2 Nondisclosure and Nonuse Obligations. Each of the parties, as
Recipient, agrees that such Recipient will not use, disseminate, or in any way
disclose any Confidential Information of the other party, as Discloser, to any
person, firm or business, except to the extent necessary for the performance of
such party's obligations or the enjoyment of such party's rights and benefits
hereunder, and for any other purpose such Discloser may hereafter authorize in
writing. Each of the parties, as Recipient, agrees that such Recipient shall
treat all Confidential Information of the other party, as Discloser, with the
same degree of care as such Recipient accords to such Recipient's own
Confidential Information, but in no case less than reasonable care. Each of the
parties, as Recipient, agrees that such Recipient shall disclose Confidential
Information of the other party, as Discloser, only to those of such Recipient's
employees who need to know such information, and such Recipient certifies that
such Recipient employees have previously agreed, either as a condition to
employment or in order to obtain the Confidential Information of the Discloser,
to be bound by terms and conditions substantially similar to those terms and
conditions applicable to such Recipient under this Agreement. Each of the
parties, as Recipient, shall immediately give notice to the other party, as
Discloser, of any unauthorized use or disclosure of Discloser's Confidential
Information. Each of the parties, as Recipient, agrees to assist the other
party, as Discloser, in remedying any such unauthorized use or disclosure of
Discloser's Confidential Information.

            9.3 Exclusions from Nondisclosure and Nonuse Obligations. The
obligations under this Section 9 of each of the parties, as Recipient, with
respect to any portion of the Confidential Information of the other party, as
Discloser, shall not apply to such portion that Recipient can document: (a) was
in the public domain at or subsequent to the time such portion was communicated
to Recipient by Discloser through no fault of Recipient; (b) was rightfully in
Recipient's possession free of any obligation of confidence at or subsequent to
the time such portion was communicated to Recipient by Discloser; (c) was
developed by employees or agents of Recipient independently of and without
reference to any information communicated to Recipient by Discloser; or (d) was
communicated by Discloser to an unaffiliated third party free of any obligation
of confidence. A disclosure by either of the parties, as Recipient, of
Confidential Information of the other party, as Discloser, either (i) in
response to a valid order by a court or other governmental body; (ii) as
otherwise required by law; or (iii) as necessary to establish the rights of
either party under this Agreement, shall not be considered to be a breach of
this Agreement by Recipient or a waiver of confidentiality for other purposes;
provided, however, that Recipient shall provide prompt prior written notice
thereof to Discloser to enable Discloser to seek a protective order or otherwise
prevent such disclosure.

            9.4 Confidentiality of this Agreement. The parties hereto agree to
keep the terms of this Agreement confidential and not to divulge any part
thereof to any third party


                                       24
<PAGE>

except: (a) with the prior written consent of the other party; (b) to any
governmental body having jurisdiction to request and to read the same; (c) as
otherwise may be required by law or legal process; or (d) to legal counsel
representing either party. Notwithstanding the foregoing, no disclosure of this
Agreement shall be made pursuant to clauses (b) or (c) of the foregoing sentence
without the disclosing party first giving the other party reasonable notice
prior to the intended disclosure so as to allow the other party sufficient time
to seek a protective order or otherwise assure the confidentiality of this
Agreement as that other party shall deem appropriate. Each party agrees not to
file this Agreement as an exhibit to its SEC filings without first redacting and
requesting confidential treatment for any information reasonably considered by
the other party to be confidential. Such other party shall inform the first
party of any such information it wishes to redact and request confidential
treatment for within five Business Days following the date such other party is
requested to do so in writing. Nothing herein shall prohibit either party from
complying with applicable securities or other laws, rules or regulations.

      10. Term; Events of Default; and Remedies.

            10.1 Term. The term of this Agreement shall commence upon the
Effective Date and continue in perpetuity.

            10.2 Events of Default. The occurrence of any one or more of the
following acts, events or occurrences shall constitute an "Event of Default"
under this Agreement: (a) either party becomes insolvent, files for bankruptcy
or is subjected to involuntary bankruptcy proceedings that are not dismissed
within 60 days, or makes a general assignment for the benefit of its creditors;
(b) either party breaches any material provision of this Agreement (excluding
(i) a breach by either party of the provisions of Section 2.17 or Exhibit D
hereto, which may not result in an "Event of Default," and (ii) a payment breach
by Converge of the type described in clause (c) below, which is covered by such
clause (c)) and the result is that the non-breaching party experiencing a
substantial deprivation of the benefits to which the non-breaching party is
entitled under this Agreement, which material breach is not cured by the
breaching party within 45 days after the breaching party's receipt of the
non-breaching party's written notice specifying the breach in detail; provided,
however, that if the breach is of such a nature that it may be cured, but it may
not reasonably be cured within such 45-day period, the non-breaching party may
not terminate this Agreement unless such breach is not cured by the breaching
party on or before the 90th day after the breaching party's receipt of the
non-breaching party's notice of breach if breaching party has commenced
substantial efforts to cure the breach within the initial 45-day period and has
continued in good faith to work to cure the breach as soon as reasonably
practicable thereafter, or (c) Converge fails to pay when due any amounts
payable under Section 3.1 and Exhibit B hereto and fails to cure such breach
within 10 Business Days after Vert gives Converge written notice specifying the
breach.

            10.3 Remedies.

                  10.3.1 Remedies of Vert. Immediately upon the occurrence of an
Event of Default by Converge under Section 10.2, Vert shall have the right, but
not the obligation, to make a "Vert Remedy Election," exercisable by delivering
written notice thereof to Converge within 10 Business Days after the occurrence
of such Event of Default by Converge. Vert shall


                                       25
<PAGE>

not have the right to terminate this Agreement upon the occurrence of an Event
of Default by Converge under Section 10.2 or any other breach by Converge under
this Agreement.

                  10.3.2 Remedies of Converge. Immediately upon the occurrence
of an Event of Default by Vert under Section 10.2, Converge shall have the
right, but not the obligation, to make a "Converge Remedy Election," exercisable
by delivering written notice thereof to Vert within 10 Business Days after the
occurrence of such Event of Default by Vert. Converge shall not have the right
to terminate this Agreement upon the occurrence of an Event of Default by Vert
under Section 10.2 or any other breach by Vert under this Agreement.

            10.4 Cataclysmic Event.

                  10.4.1 Notice and Response. Should a Cataclysmic Event occur,
Converge shall provide Vert with notice thereof as immediately as possible (a
"Cataclysmic Event Notice"). Each Cataclysmic Event Notice shall be provided to
Vert via telephone, pager and e-mail in accordance with VNS' Maintenance &
Support procedures for the reporting of a Severity Level 1 Problem, and the
Converge Tech Support representative or other Converge Personnel reporting the
Cataclysmic Event shall indicate to VNS that they are reporting a Severity Level
1 Problem. Vert shall respond to a Cataclysmic Event Notice and seek to provide
a Cataclysmic Event Cure in accordance with the provisions of Exhibit C
respecting Severity Level 1 Problems.

                  10.4.2 Efforts of Converge. Converge shall fully cooperate
with and assist Vert, as reasonably requested by Vert, in Vert's efforts to
characterize and diagnose the cause of any Cataclysmic Event and to effectuate a
Cataclysmic Event Cure with respect thereto. Without limiting the foregoing, at
any point when the Converge Marketplace is experiencing an interruption in Trade
Functionality, Converge shall use best efforts to restore such functionality to
the Converge Marketplace as soon as possible, such efforts to be in coordination
with Vert's efforts to effectuate a Cataclysmic Event Cure. Converge's efforts
under this Section 10.4.2, at a minimum, shall include implementing all
applicable Marketplace Response Procedures as immediately as practicable.

                  10.4.3 Priority Event of Default. In the event that a
Cataclysmic Event Cure is not effectuated within three days (72 hours) following
its corresponding Response Initiation Date/Time, Vert shall be in default of its
obligations under this Agreement (a "Priority Event of Default"). Should a
Cataclysmic Event Cure for such Priority Event of Default not be effectuated
within 11 days (264 hours) following the occurrence of such Priority Event of
Default, Converge shall have the right, but not the obligation, to make a
"Priority Remedy Election," exercisable by delivering written notice thereof to
Vert within 10 Business Days after the occurrence of such Priority Event of
Default. Converge shall not have the right to terminate this Agreement upon the
occurrence of a Priority Event of Default hereunder. For purposes of the
provisions of this Agreement other than those set forth in Section 10.2 and
Section 10.3, the consequences of a Priority Remedy Election by Converge shall
be the same as the consequences of a Converge Remedy Election by Converge,
unless otherwise expressly stated in this Agreement.

                  10.4.4 Tolling. The time periods specified in Section 10.4.3,
Section 10.4.5 and Section 6.6 shall be tolled for any time during which
Converge substantially fails to comply with its obligations under Section 10.4.2
to implement the applicable Marketplace Response Procedures.

                  10.4.5 Payments by Vert. In the event that Vert does not
effectuate a Cataclysmic Event Cure by the end of the third day (72nd hour)
following its corresponding Response Initiation Date/Time, Vert shall pay
Converge as liquidated damages, with respect to monetary claims, and without
limiting Converge's right to make a Priority Remedy Election (with such
liquidated damages and Priority Remedy Election being Converge's sole remedies
in connection with such Cataclysmic Event so long as this Section 10.4 applies),
the following amounts, depending on the length of time that such failure
continues:

Such payments shall be made within 30 days following the date on which the total
amount due under this Section 10.4.5 with respect to the Cataclysmic Event in
question becomes fixed.

                  10.4.6 Trigger Events. Notwithstanding anything to the
contrary in this Section 10.4, the provisions of this Section 10.4 shall not
apply with respect to any Converge Marketplace that is the subject of a
Cataclysmic Event unless and until a Trigger Event has occurred with respect to
such Converge Marketplace. Furthermore, the amounts payable by Vert to Converge
under Section 10.4.5 above with respect to a particular Converge Marketplace

Election. The provisions of this Section 10.4 shall be Converge's sole remedy in
the event this Section 10.4 applies. In addition, the provisions of this

those Products for which Converge is then purchasing Maintenance & Support
Services and (ii) if Converge is then paying for Maintenance & Support Services
at an annualized rate of at least $1,750,000 per year.

      11. Effect of Remedy Election. Upon the occurrence of a Vert Remedy
Election or a Converge Remedy Election, each party shall erase, destroy or
return to the other party all copies of the Confidential Information of or
provided by such party (which in the case of Converge as the erasing, destroying
or returning party shall include the Products and the Documentation), and, upon
such other party's written request, shall certify its compliance with this
Section 11 to the other party in writing. Notwithstanding the foregoing
provisions of this Section 11, with respect to and for so long as any licenses
granted to Converge respecting Products and/or Source Code survive a Vert Remedy
Election or a Converge Remedy Election, Converge shall not be required to erase,
destroy or return any Confidential Information of VNI or any of the VNI
Subsidiaries respecting such Products and/or Source Code.

      12. Compliance with U.S. Export Laws. Converge acknowledges that the laws

similar materials discussing this Agreement or either party's performance

parties may mutually agree upon a joint marketing program. Notwithstanding the
foregoing, Vert will be entitled to list Converge as a customer of Vert and as a
reference without submitting such lists to Converge. Converge will provide Vert
with a mutually agreed upon name (and contact information) for an employee of
Converge who will accept reference calls.

      14. General.

                         Maintenance & Support Services

1.0 Problem Handling. VNS shall be responsible for responding to Problems as set
forth in this Exhibit C. Only authorized personnel designated by Converge will
report Problems to VNS technical support personnel ("Converge Tech Support"),
the number of such Converge personnel will not exceed 50 without VNS approval.
Unless otherwise agreed in writing in a SOW executed under the PSA, Converge and
the Converge Subsidiaries shall be responsible for providing "Level 1" (help
desk-type support) support to both Converge Personnel (internal help desk) and
Converge users (external help desk), for each of the Deployed Products on which
VNS has provided the necessary training as described herein. VNS shall be
responsible for providing "Level 2" (technical inquiries and support) and "Level
3" (code fixes) support for such Deployed Products and Level 1, 2 and 3 support
for all other Products. Converge Tech Support will be the "single point of
contact" for support of the Products and the escalation of Problems in
accordance with this Exhibit C. In the case of a Deployed Product for which
Converge is proving Level 1 support, Problems will be escalated to VNS only
after such Problems have been reasonably escalated through the "Level 1" support
procedures of Converge and the Converge Subsidiaries. With respect to Problems
reported to VNS, Converge shall provide, to the extent known to Converge,
information to enable VNS to reproduce, verify, diagnose and correct such
Problems. VNS will attempt to resolve Problems reported by Converge to VNS as
set forth below.

VNS will provide all reasonable training and available training materials to
enable Converge to provide Level 1 support for the Deployed Products ("Support
Training"). Support Training will include both introductory training reasonably
in advance of when new Deployed Products are put into production by Converge and
periodic refreshers as appropriate when Updates and Enhancements of Deployed
Products are released. Support Training will be provided at mutually agreed
locations and schedules, and each party will bear its own costs and expenses
(except for reasonable travel for VNS Personnel and out-of-pocket costs for
training materials, which Converge will reimburse to VNS at cost).

All Problems shall be reported by Converge and the Converge Subsidiaries to
designated VNS technical support personnel via telephone, e-mail and/or in some
other manner agreed to by the parties. VNS will establish a process to check
incoming electronic requests for Level 2 at least once every two hours and Level
3 support at least once every four hours. VNS will maintain procedures and
systems designed to ensure that Problems are properly logged and track and all
new Error corrections are compatible with previous Error corrections. Packaging
of Error corrections will be done as mutually agreed to by the parties. VNS will
provide to Converge the names, phone numbers and 24X7 pager numbers of the VNS
support personnel to contact outside of Business Hours when high priority
Problems are encountered that require immediate assistance.

2.0 Problem Severity Levels. The following chart describes the distinctions
between the different severity levels for Problems reported by Converge and the
Converge Subsidiaries.

Severity Level    Definition

1                 A "Severity Level 1" Problem is one where critical or central
                  functionality of the Product is unavailable and the Product
                  cannot reasonably be used and/or performance of the Product is
                  severely degraded. The adverse impact of a Severity 1 Problem
                  on Converge's business is severe and immediate, and requires
                  an immediate solution.
                  -     A "Severity Level 1" Problem may have one or more of the
                        following characteristics:
                  -     Data is corrupt or Product corrupts or loses data
                  -     Complete or severe lack of ability to use the Product
                  -     Product crashes repeatedly
                  -     Product is not operational
                  -     The Product fails to run to completion or returns
                        incorrect results

2                 A "Severity Level 2" Problem is one where critical, central or
                  important functionality of the Product is restricted and/or
                  performance of the Product is significantly degraded. Use of
                  the Product can continue in a restricted fashion or the user
                  experiences a significant degradation of Product functionality
                  and/or performance.
                  o     A "Severity Level 2" Problem may have one or more of the
                        following characteristics:
                  o     A substantial loss of use of certain functionality of
                        the Product for which there is an insufficient
                        workaround
                  o     Performance of the Product is severely degraded
                  o     Some important Product functionality is unavailable or
                        improperly functioning, but the Product can continue to
                        operate in a restricted fashion

3                 A "Severity Level 3" Problem causes minimal interruption to
                  non-central or non-important functionality. The Problem has a
                  minor impact or is inconvenient.
                  o     A "Severity Level 3" Problem may have one or more of the
                        following characteristics:
                  o     Performance of the Product is degraded in a non-critical
                        manner
                  o     Performance of the Product is minimally impaired

4                 A "Severity Level 4" Problem causes no loss of use of the
                  Product.
                  o     Cosmetic Problem with the Product
                  o     Documentation error
                  o     Minor incorrect behavior of the Product that does not
                        impede its operation

3.0 Problem Response and Resolution. VNS will review all Problems reported by
Converge to determine whether they are caused by Errors. In the event of a
reasonable uncertainty, the parties will assume the higher level until they have
sufficient information to make a determination. VNS shall conduct such review
and use best efforts to provide Converge


                                       36
<PAGE>

with an initial response and status reports as set forth in the table below.
Should VNS determine that a Problem is caused by one or more Errors, VNS will
use best efforts to resolve such Errors as set forth in the table below. If
Converge unreasonably reports a Problem as being at a Severity Level that is
higher than what proves to be the actual Severity Level of the Problem, Converge
shall pay or reimburse VNS for all incremental costs and expenses incurred by
VNS in reviewing and responding to the Problem as a higher Severity Level
Problem. If VNS' review of, or response to, a Problem reported by Converge
establishes that the Problem was not due to an Error, Converge shall pay or
reimburse VNS for all costs and expenses reasonably incurred by VNS in reviewing
and responding to the Problem.

In addition to individual Problem reporting as described below, commencing not
later than July 1, 2001, VNS will provide to Converge a weekly status log of
Problem tickets to include: severity level of Problem as reported by Converge,
severity level of Problem as determined by VNS, date and time each Problem was
reported, date and time of initial response for each reported Problems, date and
time of status for each reported, date and time of diagnosis for each reported,
and date and time of work-around or fix. Between the Effective Date and July 1,
2001, VNS shall provide coverage with all reasonably available information of a
similar nature.

                 Marketplace Protection Measures and Procedures

Converge Web Sites - Marketplace Protection Measures

      -     Deployment of a data-reliability architecture relying on multiple
            data centers in geographically disparate locations for all core
            functions of the Converge Web Site
      -     Industry-Standard efforts to restrict access to data centers.
      -     Industry-Standard hardware and software designed to provide
            transparent failover from one data center to another.
      -     Industry-Standard measures to protect the data centers from damage
            due to fire, water, storms, flood, vandalism, and other similar
            events.
      -     Industry Standard use of uninterruptible power supplies for all
            appropriate data center components.
      -     Deployment of reliable storage media, such as RAID 5 disks.
      -     Active monitoring of failures so as to allow restart of failed
            systems and replacement of systems in the event of failure, without
            loss of significant data.
      -     Industry Standard techniques for monitoring of disk and memory
            usage, including "water-level"-based alarm approaches designed to
