                  2.1.1 to use, load, store, transmit, execute, copy, distribute

                  2.2.1 No Restrictions on Number of Users. There shall be no
restriction on the number of subscribers to or registered users of, or numbers
of transactions conducted on or through, any Converge Marketplace.

herein, neither Converge nor any Converge Subsidiary shall be obligated to pay
any fees to Vert based upon the number of subscribers to or registered users of,

attempt to assess or collect fees from, third-party users for any use of
Products through or via use of any Converge Marketplace.

                  2.2.3 Third Party Licenses. When considering whether to
implement any new instantiations of Products, Converge shall consult with Vert
and Vert shall inform Converge whether such new instantiations would require
Vert to pay any significant third-party license fees in connection therewith. In
determining whether to implement such instantiations, Converge shall, in good
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.

third parties' computing environments (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 the Converge Marketplace to accept
membership agreements that are (a) at least as protective of Vert's Intellectual
Property Rights as this Agreement and (b) are otherwise consistent with
customary and usual agreements of that type in the industry. Converge or the
applicable Converge Subsidiary shall provide VNS with the total number of
instantiations of each Product component being deployed 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.

                  2.3.3 No Additional Sublicenses. Except as expressly set forth

2.4.5), worldwide (subject to qualification as set forth in Section 2.5),
non-exclusive, non-transferable (except in the event of a permitted transfer of
this Agreement under Section 14.11), and non-sublicensable right and license to

or distribution technology whatsoever, known or unknown, display, modify and
have modified, and make and have made Derivative Works of, any Source Code

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

right to engage third-party consultants that are Converge-certified system
integrators to perform such activities on behalf of Converge; provided, however,

be bound by obligations of nondisclosure and nonuse no less stringent than those

the contrary in this Agreement or in the provisions of the Professional Services
Agreement that survive the termination thereof (as set forth in the PSA
Termination Agreement), 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 C as "Japan-Restricted Community Products" or
"Japan-Restricted Content Products" (the "Japan-Restricted Community and

                                       9
<PAGE>

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 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.

            2.7 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 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.

            2.8 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.

            2.9 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

                                       10
<PAGE>

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.

            2.10 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.

            2.11 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.

            2.12 Delivery. During the Product Term, subject to the provisions of
Section 12, Vert shall offer to deliver to Converge all Future Products and any
Vert-General Release Enhancements promptly following the date on which Vert
makes the same generally available to its other customers, or, if Vert makes
such items available as beta or other early release versions, promptly following
the date on which Vert makes the same available in such format to any of its
other customers; provided, however, that Vert shall not be obligated to provide
Maintenance and Support Services under the Maintenance and Support Agreement for
such pre-release versions, and such pre-release versions shall not be used in a
production environment without Vert's consent). If Converge elects to implement
and deploy any such Future Product or Vert-General Release Enhancement, Vert
shall deliver same to Converge pursuant to Section 2.13. As set forth in Section
12 and notwithstanding any other provision in this Agreement to the contrary,
the Product Term shall not end upon the occurrence of a Prohibited Change in
Control Remedy Election, but Converge's right to receive Future Products
released by Vert after the Prohibited Change in Control Remedy Election Date, as
well as any Vert-General Release Enhancements to such Future Products, shall
automatically terminate. From and after the Prohibited Change in Control Remedy
Election Date, until the end of the Product Term, Vert shall only be obligated
to deliver to Converge Vert-General Release Enhancements to Products that are
Deployed Products as of the occurrence of the Prohibited Change in Control.

            2.13 Method of Delivery and Acceptance. Vert will transfer Products
and any associated Documentation by remote telecommunications from the Vert
place of business, to a Converge computer at a Converge place of business
located in the Commonwealth of Massachusetts. If any such Product and/or
associated Documentation cannot be delivered via remote telecommunications to a
Converge computer located at a Converge place of business in the Commonwealth of
Massachusetts, such Product and/or Documentation will be installed by Vert on a
Converge computer located at a Converge place of business in the Commonwealth of

                                       11
<PAGE>

Massachusetts, if any. 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 or associated Documentation under this Agreement. Each
Product delivered by Vert to Converge will be deemed accepted by Converge upon
Converge's receipt of the complete delivery to a Converge computer located at a
Converge place of business.

            2.14 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.

      3. Fees and Payments.

            3.1 Fees for Products.

                  3.1.1 General.

                        (A) The fees for the license rights granted to the
Products and for Maintenance and Support Services to be provided during the
Product Term are set forth in Part I of Exhibit B hereto. Converge shall pay
such fees to VNS in accordance with the provisions of Part I of Exhibit B. In
addition, Converge's payment obligations under Section 3.1 and Exhibit B of the
Original SLA (described in Part II of Exhibit B hereto) shall survive the
amendment and restatement of the Original SLA pursuant to this Agreement on a
deferred basis (i.e., not be due and payable as long as the payments described
in the first two sentences of this Section 3.1 and in Part I of Exhibit B hereto
are made), and such surviving payment obligations are subject to being released
in full in accordance with the following provisions of this Section 3.1.1.

                        (B) Subject to the conditions (which may be waived by
VNS pursuant to a written waiver signed by an authorized officer of VNS) that
(i) Converge pays when due each of the payments required to be made by it under
the Part I of Exhibit B hereto and the Maintenance and Support Agreement (and
VerticalNet receives good funds in the amount of each such payment) for the
period from and including the Effective Date to and including May 1, 2002, (ii)
no such payment made by Converge is recovered, recaptured or avoided including,
without limitation, by or on behalf of Converge or any bankruptcy trustee or
creditor of Converge, on or before the Release Date (defined below), and (iii)
Converge does not file for bankruptcy on or before the Release Date, is not
subjected to involuntary bankruptcy proceedings that are not dismissed within 60
days or if earlier, the Release Date, and Converge does not make a general
assignment for the benefit of its creditors on or before the Release Date, then:
(a) upon the receipt by VNS of each payment by Converge under Part I of Exhibit
B hereto, Converge's surviving and deferred payment obligations under the
Original SLA (set forth in Part II of Exhibit B hereto) shall be reduced by an
amount equal to the payment made by Converge (50% of each payment made shall be
applied to reduce Converge's surviving payment obligations under the Original
SLA next becoming due at the time of application; and 50% of each payment made
shall be applied to reduce Converge's surviving payment obligations under the
Original SLA last becoming due at the time of application); and (b) effective on
the later date (the "Release Date") to occur of August 1, 2002 or the 91st day
after Converge has made the payments required to be made by it on May 1, 2002
under Part I of Exhibit B hereto and the

                                       12
<PAGE>

Maintenance Agreement, Converge's surviving and deferred payment obligations
under the Original SLA (set forth in Part II of Exhibit B hereto) shall be
forgiven in full and Converge shall be released from all such surviving and
deferred payment obligations in full.

                        (C) If (1) Converge fails to pay when due any of the
payments required to be made by it under the Part I of Exhibit B hereto or the
Maintenance and Support Agreement (or if VerticalNet does not receive good funds
in the amount of any such payment) for the period from and including the
Effective Date to and including May 1, 2002 and fails to cure such breach within
the applicable cure period specified in this Agreement or in the Maintenance
Agreement, as applicable (and Vert does not waive such default and Vert's right
to receive such payment pursuant to a written waiver signed by an authorized
officer of Vert), or (2) any such payment made by Converge is recovered,
recaptured or avoided, or (3) if Converge files for bankruptcy on or before the
Release Date, is subjected to involuntary bankruptcy proceedings that are not
dismissed within 60 days or if earlier, the Release Date, or if Converge makes a
general assignment for the benefit of its creditors on or before the Release
Date, and Vert does not waive such failure, recovery, recapture, avoidance,
filing or occurrence pursuant to a written waiver signed by an authorized
officer of Vert, then the conditional reduction of, and agreement to forgive
Converge's surviving and deferred payment obligations under the Original SLA
(set forth in Part II of Exhibit B hereto) pursuant to the preceding sentence
shall automatically be terminated, null and void without any further action by
Vert. In such event, any reduction of Converge's surviving and deferred payment
obligations under the Original SLA (set forth in Part II of Exhibit B hereto)
shall be reversed and all such amounts shall be due and owing by Converge, but
such amounts shall be reduced by the amount of any payments that were made by
Converge to Vert under Part I of Exhibit B and were not recovered, recaptured or
avoided after payment was made.

                        (D) The provisions of this Agreement including, without
limitation, the provisions of this Section 3.1, reflect a financial
accommodation in favor of Converge.

                  3.1.2 Converge Remedy Election. Subject to the provisions of
Section 3.1.1 relating to the deferral, reduction and release of Converge's
payment obligations under Section 3.1 and Exhibit B of the Original SLA
(described in Part II of Exhibit B hereto), the only event that shall relieve
Converge of its obligation to pay the fees pursuant to 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, subject to the
provisions of Section 3.1.1 relating to the deferral, reduction and release of
Converge's payment obligations under Section 3.1 and Exhibit B of the Original
SLA (described in Part II of Exhibit B hereto), 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 or Prohibited Change in Control
Remedy Election. Notwithstanding the occurrence of a Vert Remedy Election or a
Prohibited Change in Control Remedy Election, subject to the provisions of
Section 3.1.1 relating to the deferral, reduction and release of Converge's
payment obligations under Section 3.1 and Exhibit B of the Original SLA
(described in Part II of Exhibit B hereto), Converge shall remain obligated to
pay

                                       13
<PAGE>

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 or the Prohibited Change in
Control Remedy Election Date.

            3.2 Payments. All payments will be made by Converge in U.S. dollars,
without setoff, recoupment or deduction. Amount payable hereunder (other than
fees payable under Section 3.1) 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.

            3.3 Taxes. 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 3.2), 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).
Subject to the express provisions of this Agreement, the parties will cooperate
and use their commercially reasonable efforts to minimize or avoid, to the
maximum extent allowed by law, the obligation to pay any Sales Taxes that may be
levied on payments made under this Agreement or otherwise are chargeable by any
applicable government authority with respect to the Products or services under
this Agreement.

            3.4 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.

                                       14

      4. Disclaimer of Warranties. WITH THE EXCEPTION OF 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, ACCURACY, FITNESS FOR A PARTICULAR PURPOSE, QUIET
ENJOYMENT AND NON-INFRINGEMENT OF THIRD PARTY RIGHTS RELATING TO THE PRODUCTS
AND ANY SERVICES FURNISHED OR OTHERWISE PROVIDED OR TO BE PROVIDED HEREUNDER.

      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
surviving provisions of the Professional Services Agreement (specified in the
PSA Termination Agreement) with respect to Deliverables 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, 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
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 surviving provisions of the Professional Services Agreement
(set forth in the PSA Termination 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. Vert has delivered to the Escrow Agent, to be
held in escrow pursuant to the Escrow Agreement, true and complete copies of the
Source Code for the Initial Deployed 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, but excluding the Source Code for
the Structured Negotiations Product) 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 owned by VNI or any the VNI Subsidiaries becomes a Deployed
Product under this Agreement,

                                       15
<PAGE>

or an Enhancement or Maintenance Update for a Deployed Product becomes generally
available, but in any event at least once per calendar quarter, Vert shall
deliver to the Escrow Agent the Source Code for such other Deployed Products,
Enhancements and Maintenance Updates (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) to be held in escrow pursuant to
the provisions of the Escrow Agreement. 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 and Support Services for a
Deployed Product other than as a result of the expiration or termination of the
Maintenance and Support Agreement in accordance with its terms; (c) a Vert
Non-Renewal Election occurs and Vert fails to deliver to Converge the Source
Code for all Deployed Products within the time period specified in Section 2.4.3
above; or (d) a Converge Non-Renewal Election occurs and Vert fails to deliver
to Converge the Source Code for all Initial Deployed Products within the time
period specified in Section 2.4.3 above. Notwithstanding anything to the
contrary herein, (i) if the claimed Release Event is under clause (b) above,
only the Escrow Materials for the Product that is the subject of the Release
Event, together with all associated Maintenance Updates and Enhancements, shall
be subject to release to Converge hereunder; (ii) if the claimed Release Event
is under clause (c) above, only the Escrow Materials for the Deployed Products,
together with all associated Maintenance Updates and Enhancements, shall be
subject to release to Converge hereunder; and (iii) if the claimed Release Event
is under clause (d) above, only the Escrow Materials for the Initial Deployed
Products, together with all associated Maintenance 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, the Escrow Agent shall be instructed to deliver the relevant Escrow
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

                                       16
<PAGE>

deposited with the Escrow Agent and to be held in escrow in accordance with the
provisions of this Section 6 and the Escrow Agreement.

      7. Limitation of Liability.

            7.1 Disclaimer of Certain Damages.

                  7.1.1 Consequential and Similar Damages. TO THE MAXIMUM EXTENT
PERMITTED BY LAW, IN NO EVENT SHALL EITHER PARTY BE LIABLE OR OBLIGATED IN ANY
MANNER FOR ANY SPECIAL, INCIDENTAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES OF ANY
KIND ARISING OUT OF OR RELATING TO THIS AGREEMENT (INCLUDING, BUT NOT LIMITED
TO, LOST PROFITS, REVENUES OR BUSINESS OPPORTUNITIES) HOWEVER CAUSED AND
REGARDLESS OF THE FORM OF ACTION, WHETHER IN CONTRACT, TORT, NEGLIGENCE, STRICT
PRODUCT LIABILITY, OR OTHERWISE, EVEN IF THE PARTY HAS BEEN INFORMED OF THE
POSSIBILITY OF ANY SUCH DAMAGES IN ADVANCE. The foregoing limitation is
independent of any exclusive remedies available to either party under this
Agreement including any failure of such remedies.

                  7.1.2 Loss of Data, Usage, Etc. VERT DOES NOT GUARANTEE THAT
THE PRODUCTS WILL 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.

            7.2 Sole Remedy. IF A CLAIM OR CAUSE OF ACTION IS ATTRIBUTABLE TO A
PRODUCT OR ANY SERVICES PROVIDED OR TO BE PROVIDED UNDER THIS AGREEMENT, THE
REMEDIES SET FORTH IN THIS AGREEMENT, TO THE EXCLUSION OF THE REMEDIES SET FORTH
IN THE MAINTENANCE AND SUPPORT AGREEMENT, SHALL CONSTITUTE THE SOLE AND
EXCLUSIVE REMEDIES AVAILABLE TO A PARTY FOR SUCH CLAIM OR CAUSE OF ACTION. IF A
CLAIM OR CAUSE OF ACTION IS ATTRIBUTABLE TO A MAINTENANCE UPDATE, ENHANCEMENT OR
ANY SERVICES PROVIDED UNDER THE MAINTENANCE AND SUPPORT AGREEMENT, THE REMEDIES
SET FORTH IN THE MAINTENANCE AND SUPPORT AGREEMENT, TO THE EXCLUSION OF THE
REMEDIES SET FORTH IN THIS AGREEMENT, SHALL CONSTITUTE THE SOLE AND EXCLUSIVE
REMEDIES AVAILABLE TO A PARTY FOR SUCH CLAIM OR CAUSE OF ACTION. For the sake of
clarity, the parties acknowledge that claims concerning Vert's ownership of and
Converge's license rights to any Maintenance Updates, Enhancements or associated
Documentation shall be deemed to have arisen under this Agreement, that claims
with respect to Vert's delivery of any Vert-General Release Enhancements or
associated Documentation, or the performance or non-performance of any
Vert-General Release Enhancements, shall be deemed to have arisen under this
Agreement, and that claims with respect to Vert's delivery of any Maintenance
Updates, Converge-Requested Enhancements or associated Documentation, or the
performance or non-performance of any Maintenance Updates or Converge-Requested
Enhancements, shall be deemed to have arisen under the Maintenance and Support
Agreement. NO LIABILITY SHALL EXTEND UNDER THIS AGREEMENT TO

                                       17
<PAGE>

ANY THIRD PARTY (INCLUDING, BUT NOT LIMITED TO, ANY AFFILIATES OF VNI OTHER THAN
VNS, OR THEIR LICENSORS) IF NOT INVOLVED IN THE DEVELOPMENT, LICENSING OR
DELIVERY OF THE PRODUCTS OR ANY SERVICES HEREUNDER.

            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
CLAIMS FOR DAMAGES, OR CLAIMS FOR INDEMNIFICATION UNDER SECTION 8, IF ANY,
RELATING TO THIS AGREEMENT OR THE PRODUCTS OR SERVICES PROVIDED OR TO BE
PROVIDED HEREUNDER, WHETHER FOR BREACH OF CONTRACT OR WARRANTY, STRICT
LIABILITY, NEGLIGENCE OR OTHER TORT, STRICT PRODUCT LIABILITY, THE FAILURE OF
ANY LIMITED REMEDY TO ACHIEVE ITS ESSENTIAL PURPOSE, OR OTHERWISE, SHALL NOT
EXCEED: (I) FOR ALL CLAIMS IN THE AGGREGATE, $3,000,000, AND (II) FOR ANY
INDIVIDUAL CLAIM, THE GREATER OF $1,000,000 PER PRODUCT OR THE LIST PRICE OF
SUCH PRODUCT AS OF THE DATE ON WHICH THE CLAIM OR CAUSE OF ACTION FIRST AROSE.
THE FOREGOING LIMITATIONS ON EACH PARTY'S AGGREGATE LIABILITY TO THE OTHER SHALL
BE IN ADDITION TO ANY FEES AND OTHER AMOUNTS DUE AND OWING UNDER SECTION 3. FOR
PURPOSES OF THIS SECTION 7.3, THE TERM "PARTY" MEANS CONVERGE ON THE ONE HAND,
AND VNI AND VNS COLLECTIVELY ON THE OTHER HAND, SO THAT AS TO VNI AND VNS THE
LIMITATIONS IN THIS SECTION 7.3 ARE COLLECTIVE LIMITATIONS AND NOT SEPARATE
LIMITATIONS FOR EACH OF VNI AND VNS.

            7.4 Exceptions. THE LIMITATIONS OF LIABILITY CONTAINED IN THIS
SECTION 7 SHALL NOT APPLY WITH RESPECT TO (A) ANY CLAIMS OF BODILY INJURY OR
DAMAGE TO TANGIBLE PERSONAL PROPERTY RESULTING FROM WILLFUL MISCONDUCT OR GROSS
NEGLIGENCE, (B) ANY BREACH OF THE PROVISIONS GOVERNING LICENSE RIGHTS AND
RESTRICTIONS IN SECTION 2, (C) ANY BREACH OF THE CONFIDENTIALITY OBLIGATIONS IN
SECTION 9, OR (D) LIABILITY FOR PAYMENT OF INTEREST ADDED BY A COURT OF LAW OR
AN ARBITRATION PANEL TO A JUDGMENT ENTERED IN ANY ACTION OR PROCEEDING UNDER
THIS AGREEMENT.

            7.5 Duty to Mitigate. Each party will have a duty to take reasonable
steps to mitigate damages for which the other party is responsible.

            7.6 Acknowledgement. Each of the parties acknowledge that the
disclaimers and limitations set forth in this Section 7 are an essential element
of this Agreement between the parties and that the parties would not have
entered into this Agreement without such disclaimers and limitations.

      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 that are developed based on unique specifications or requirements
provided or selected by Converge, to the extent that such portion is the cause
of such infringement; (d) with respect to any Initial Deployed Product, any
infringement claims concerning any U.S. patent, European Union Office patent or
patent of a country in the European Union issued after the Effective Date; and
(e) with respect to any other Product, any infringement claims concerning any
U.S. patent, European Union Office patent or patent of a country in the European
Union issued after the date such Product becomes a Deployed Product. For the
purposes of this Section 8.1, the term "Products" shall exclude the Vert-Owned
Deliverables and Converge-Requested Enhancements.

                  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 by reason
of any actual or threatened Converge Claim for which Vert is required to
indemnify Converge under Section 8.1.1, 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 Products;
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.

                                       19
<PAGE>

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 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 Products and pay to Converge the list price charged by Vert for such
Products and, with respect to Converge-Requested Enhancements, the amount paid
by Converge for such Enhancements.

                  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 THAT
SURVIVE IN ACCORDANCE WITH THE PSA TERMINATION 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 THAT SURVIVE IN ACCORDANCE WITH THE
PSA TERMINATION 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, but such exception shall not apply to the extent that the alleged
infringement or misappropriation (1) arises out of or relates to (A) a
modification of the Product by Converge or at the direction of Converge by
anyone other than Vert, to the extent that such modification is the cause of
such infringement; (B) a combination of the Product 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; or (C) portions
of the Product that are developed based on unique specifications or requirements
provided or selected by Converge, to the extent that such portion is the cause
of such infringement; and (2) concerns any

                                       20
<PAGE>

U.S. patent, European Union Office patent or patent of a country in the European
Union issued on or before the date on which such modified, combined or developed
Product is first implemented or utilized by Converge on an ongoing basis in
conjunction with the maintenance, enhancement and operation of the Converge
Marketplace (such date, a "Converge Modification Deployment Date"); (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.

            8.3 Expiration of Obligations. The rights and obligations of each
party under this Section 8 shall automatically terminate with respect to any
Converge Claims not identified by Converge to Vert in writing, and any Vert
Claims not identified by Vert to Converge in writing, as of the second
anniversary of (a) with respect to Converge Claims concerning any Initial
Deployed Product, the Effective Date; (b) with respect to Converge Claims
concerning any other Product, the date on which such Product becomes a Deployed
Product; and (c) with respect to Vert Claims, the sooner of the applicable
Converge Modification Deployment Date or the date the Product Term ends.

      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

                                       21
<PAGE>

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 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 unless terminated by parties in
accordance with the provisions of Section 14.1.

                                       22
<PAGE>

            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 a
payment breach by Converge of the type described in clause (c) below, which is
covered by such clause (c)) and the result is the non-breaching party
experiencing a substantial deprivation of the benefits to which the
non-breaching party is entitled under this Agreement, or of the value of the
non-breaching party's Intellectual Property Rights, 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 three (3) 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(a), (b) or (c), 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 not have the
right to terminate this Agreement upon the occurrence of an Event of Default by
Converge under Section 10.2(a), (b) or (c) 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.

      11. Effect of Remedy Election. Upon the occurrence of a Vert Remedy
Election or a Converge Remedy Election, the Product Term shall end effective on
the Vert Remedy Election Date or the Converge Remedy Election Date, as
applicable, and each party shall erase, destroy or return to the other party all
copies of the Confidential Information of or provided by such party, and, upon
such other party's written request, shall certify its compliance with this
Section 11 to the other party in writing. Effective as of the Vert Remedy
Election Date or the Converge Remedy Election Date, as applicable, Converge's
right to receive Future Products released by Vert thereafter, as well as any
Vert-General Release Enhancements to such Future Products, shall automatically
terminate. Notwithstanding the foregoing provisions of this Section 11, (a) with
respect to and for so long as any licenses granted to Converge respecting
Products survive a

                                       23
<PAGE>

Vert Remedy Election or a Converge Remedy Election, as applicable, Converge
shall not be required to erase, destroy or return such Products or any
Confidential Information of VNI or any of the VNI Subsidiaries respecting such
Products, and (b) with respect to and for so long as any licenses granted to
Converge respecting Source Code survive a Converge Remedy Election, Converge
shall not be required to erase, destroy or return such Source Code or any
Confidential Information of VNI or any of the VNI Subsidiaries respecting such
Source Code. With respect to the payment obligations of Converge relating to the
effect or lack of effect of a Converge Remedy Election or Vert Remedy Election,
respectively, the provisions of Section 3.1.2 and/or Section 3.1.3 shall apply.

      12. Prohibited Change in Control of Converge. If a Prohibited Change in
Control of Converge shall occur at any time during the term of this Agreement,
Vert shall have the right, but not the obligation, to make a "Prohibited Change
in Control Remedy Election," exercisable by delivering written notice thereof to
Converge within 10 Business Days after Vert receives written notice of the
occurrence of the Prohibited Change in Control of Converge, or the Prohibited
Change in Control of Converge is publicly announced. Upon the occurrence of a
Prohibited Change in Control Remedy Election, the Product Term shall not end but
Converge's right to receive Future Products released by Vert after the
Prohibited Change in Control Remedy Election Date, as well as any Vert-General
Release Enhancements to such Future Products, shall automatically terminate.
From and after the Prohibited Change in Control Remedy Election Date, until the
end of the Product Term, Vert shall only be obligated to deliver to Converge
Vert-General Release Enhancements to Products that are Deployed Products as of
the occurrence of the Prohibited Change in Control. With respect to the payment
obligations of Converge relating to the lack of effect of a Prohibited Change in
Control Remedy Election the provisions of Section 3.1.3 shall apply.

      13. Compliance with U.S. Export Laws. Converge acknowledges that the laws
and regulations of the United States may restrict the export and re-export of
commodities and technical data of United States origin, including the Products
and the Documentation in any medium. Each party agrees that it will not export
or re-export the Products or the Documentation in any form without the
appropriate United States and foreign government licenses.

      14. General.

            14.1 Termination and Survival. This Agreement and all rights and
licenses granted herein may be terminated only upon written agreement of the
parties. Upon any such termination, Section 1, Section 2.9, Section 4, Section
5, Section 7, Section 8, Section 9, Section 13 and Section 14 shall survive.

            14.2 Notices. All notices permitted or required under this Agreement
("Notices") shall be in writing and shall be delivered as follows with notice
deemed given as indicated (a) by personal delivery when delivered personally;
(b) by overnight courier upon written verification of receipt; or (c) by
certified or registered mail, return receipt requested, five days after deposit
in the mail. All Notices shall be properly addressed as follows, or to such
other addresses as may be specified in a Notice given hereunder:

If to Converge:

Attn: General Counsel
Converge, Inc.

            14.3 Force Majeure. Except for the obligation to pay monies due,
neither party shall be liable hereunder by reason of any failure or delay in the
performance of its obligations hereunder (except for the payment of money) on
account of strikes, riots, insurrection, fires, flood, storm, explosions, acts
of God, war, governmental action, labor conditions, earthquakes, or any other
cause which is beyond the control of such party.

            14.4 Waiver. An effective waiver under this Agreement must be in
writing signed by the party waiving its right. The failure of either party to
require performance by the other party of any provision hereof shall not affect
the full right to require such performance at any time thereafter; nor shall the
waiver by either party of a breach of any provision hereof be taken or held to
be a waiver of subsequent breaches of that or any other provision hereof.

            14.5 Severability. In the event that any provision of this Agreement
shall be unenforceable or invalid under any applicable law or be so held by
applicable court decision, such unenforceability or invalidity shall not render
this Agreement unenforceable or invalid as a whole, and, in such event, such
provision shall be changed and interpreted so as to best accomplish the
objectives of such provisions within the limits of applicable law or applicable
court decisions.

            14.6 Headings. The section headings appearing in this Agreement are
inserted only as a matter of convenience and in no way define, limit, construe
or describe the scope or extent of such section or in any way affect such
section.

            14.7 No Solicitation. During the Product Term and for a period of
one year thereafter, Converge and Vert each agree not to directly or indirectly
solicit, encourage or cause others to solicit or encourage any employees or
individual independent contractors of the other party to terminate their
employment or independent contracting relationship with the other party and
become an employee or independent contractor of the soliciting party or its
Affiliate. This provision does not prohibit a party's responding to unsolicited
employment inquiries and/or any indirect solicitations and other employment
activities (e.g., job postings, advertising of positions) that are not
specifically targeted at any particular individual. In the event of a
Vert-Non-Renewal Election, the provisions of this Section 14.7 shall cease to
apply with respect to Converge's solicitation or encouragement of any of the VNE
Service Personnel (as such term is

                                       25
<PAGE>

defined in the Maintenance and Support Agreement) to terminate their employment
or independent contracting relationship with Vert and become an employee or
independent contractor of Converge or its Affiliate.

            14.8 Choice of Law; Waiver of Jury Trial; Limitation of Action. This
Agreement and performance under this Agreement shall be governed by the laws of
the United States of America and of the Commonwealth of Pennsylvania as applied
to agreements entered into and to be performed entirely within Pennsylvania
between Pennsylvania residents, excluding its conflicts of law provisions. The
United Nations Convention on Contracts for the International Sale of Goods is
specifically excluded from application to this Agreement. The parties expressly
waive any right to a jury trial regarding disputes related to this Agreement.
Unless otherwise provided by local law without the possibility of contractual
waiver or limitation, any legal or other action related to this Agreement must
be commenced no later than two years from the date on which the cause of action
arose.

            14.9 No Agency. Nothing contained herein shall be construed as
creating any agency, partnership or other form of joint enterprise between the
parties or to allow either party to bind the other or incur any obligation on
its behalf.

            14.10 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original and all of which
together shall constitute one and the same instrument. This Agreement shall
become binding when any one or more counterparts hereof, individually or taken
together, bear the signatures of both parties hereto. For the purposes hereof, a
facsimile copy of this Agreement, including the signature pages hereto, shall be
deemed an original.

            14.11 Assignment. A party may assign this Agreement to any
Affiliate. Otherwise, neither party may assign this Agreement without the other
party's prior written consent (not to be unreasonably withheld). No transfer of
this Agreement by operation of law or change in Control of a party, including,
without limitation, by merger, consolidation or sale or other transfer of equity
interests, shall be considered an assignment for purposes of this Section 14.11.
However, if a Prohibited Change in Control of Converge occurs, Vert shall have
the right to make a Prohibited Change in Control Remedy Election under Section
12. This Agreement will bind and inure to the benefit of the parties and their
respective successors and permitted assigns.

            14.12 No Third-Party Beneficiaries. Except as expressly stated in
Section 8, nothing in this Agreement is intended to confer benefits, rights or
remedies unto any person or entity other than the parties and their successors
and permitted assigns.

            14.13 Non-Exclusive Agreement. Except as expressly stated herein,
this Agreement is not exclusive as to either party, and, subject to the express
provisions of this Agreement, each party will have the right to conduct any
other business in which it may now or hereafter be engaged.

            14.14 Entire Agreement. This Agreement, together with the PSA
Termination Agreement, the Maintenance and Support Agreement and the Escrow
Agreement, are the entire

                                       26

agreement between Vert and Converge relating to the subject matter of this
Agreement. This Agreement shall supersede any prior agreement or understanding,
whether written or oral, and any other communications between Vert and Converge
relating to the subject matter of this Agreement. This Agreement may only be
amended by a writing specifically referencing this Agreement, which has been

            2.2 Converge Support Personnel. Only authorized personnel designated
by Converge ("Converge Support Personnel") may communicate Problem Reports and
Support

                                        3
<PAGE>

Requests to VNE. The number of Converge Support Personnel will not exceed seven
persons without VNE's prior approval. The initial Converge Support Personnel
shall be identified to VNE in writing within 10 business days following the
Effective Date. Converge may change the Converge Support Personnel on written
notice to VNE; provided, however, that Converge shall use reasonable efforts not
to change the Converge Support Personnel more frequently than once every 30
days. All replacement personnel shall be required to participate in Support
Training as described in Section 3.3 below. Converge Support Personnel will be
the "single point of contact" for the Maintenance and Support Services provided
by VNE under this Section 2.

            2.3 Method of Reporting. All Problem Reports and Support Requests
shall be communicated by the Converge Support Personnel to VNE as follows: (1)
via telephone at 1-877-249-1423, or such other telephone number(s) as VNE may
provide to Converge from time to time, or (2) via electronic mail to
support.solutions@verticalnet.com, or such other e-mail address(es) as VNE may
provide to Converge from time to time, or (3) in person to VNE Service Personnel
(if any) on Converge premises at the time; provided, however, that the Converge
Support Personnel shall communicate all Severity Level 1 and Severity Level 2
Problems to VNE via method (1) or method (3) above. Converge shall classify all
Problems reported to VNE according to the Problem Severity Levels listed in
Exhibit A attached hereto.

            2.4 Support Responsibilities. Converge and the Converge Support
Personnel 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 Supported Products on which VNE has
provided training as set forth in Section 3.3 below. Subject to the provisions
of this Section 2, VNE shall be responsible for providing "Level 2" (responding
to technical inquiries) and "Level 3" (code fixes) support for such Supported
Products. In the case of Supported Products for which Converge is providing
Level 1 support, Converge shall not escalate Problem Reports or Support Requests
to VNE until such Problem Reports or Support Requests have been reasonably
escalated through the "Level 1" support procedures of Converge. In addition,
Converge shall conduct reasonable problem identification and isolation
activities to determine whether or not a given problem relates to the Products
(i.e., whether a "Problem" as defined exists). Converge shall not escalate
Problem Reports or Support Requests to VNE prior to conducting such activities
or if Converge has determined that the Problem Report or Support Request does
not relate to the Supported Products.

            2.5 Additional Information for Problems. With respect to each
Problem reported to VNE, Converge shall provide, at the time the Problem Report
is communicated to VNE and to the extent known to or reasonably ascertainable by
Converge, information that will enable VNE to reproduce (in as complete a
step-by-step manner as is reasonably possible), or verify the existence of the
Problem, plus any additional information regarding the Problem that Converge
believes will assist in the diagnosis thereof and response thereto. The parties
shall reasonably cooperate to obtain and provide to VNE any additional
information about the reported Problem that may be relevant to diagnosing and
responding thereto. In the event that Converge is unable to make a determination
based on the problem identification and isolation activities described in
Section 2.4 or reproduce, or provide the information necessary for VNE to
diagnose or reproduce, any Problem, Converge may request VNE's assistance in
performing identification and isolation or reproducing the Problem and/or
generating or documenting such information.

                                        4
<PAGE>

            2.6 Response to Problem Reports. VNE shall use its reasonable best
efforts to provide Converge with an initial response to and status reports for
all Problems reported by Converge, and to resolve all Problems identified, in
accordance with the provisions of Exhibit B attached hereto; provided, however,
that VNE shall have no further obligation to respond to or attempt to diagnose
or resolve a Problem once it is determined not to be attributable to Errors. VNE
will review all Problem Requests submitted by Converge at the Problem Severity
Level indicated by Converge unless another Problem Severity Level is clearly
warranted. In the event of a reasonable uncertainty, the parties will assume a
higher Severity Level for a Problem until they have sufficient information to
make a determination that a lower Severity Level is warranted. If, at Converge's
request, VNE responds to a Problem at a Severity Level that is higher than what
proves to be the actual Severity Level of the Problem, or if VNE's review of a
Problem reported by Converge establishes that the Problem was not due to an
Error, Converge shall pay or reimburse VNE for all incremental fees and expenses
reasonably incurred by VNE in performing such activities.

            2.7 Response to Support Requests. VNE shall respond to all Support
Requests submitted by Converge within a reasonable period of time, taking into
consideration the nature of the Support Request, its impact on Converge's
business operations and any Problem Reports or other Support Requests VNE is
responding to at such time.

            2.8 Tracking Procedures. VNE will maintain procedures and systems
designed to ensure that Problem Reports and Support Requests submitted by
Converge are properly logged and tracked. In addition, VNE will provide to
Converge a weekly status log of Problem Reports and Support Requests currently
being tracked. Such report shall identify, as appropriate, each Problem Report
or Support Request as submitted by Converge, the Severity Level for each
identified Problem, the date and time each Problem Report or Support Request was
received by VNE, an assessment of the Problem Report or Support Request and an
action plan detailing the proposed method of resolution, and an estimated time
schedule for delivery of any necessary Error corrections.

            2.9 Remote Access. Converge shall provide VNE with remote access,
via modem, the Internet or some other remote communications method mutually
agreed-upon by the parties and subject to Converge's network security procedures
and requirements, to Converge's servers on which the Supported Products are
installed for the sole and limited purpose of enabling VNE to fulfill its
obligation to provide Maintenance and Support Services hereunder. Converge shall
be responsible for all costs associated with providing data network connectivity
at the point of connectivity to Converge's data network. The parties will share
equally in the cost of such connectivity between VNE's facilities and Converge's
facilities (including all associated telecommunications charges). VNE shall not
be responsible for any delay in providing Maintenance and Support Services under
this Agreement to the extent such delay is due to Converge's adoption of
unreasonable network security procedures or requirements.

            2.10 Provision of Maintenance Updates. VNE shall provide Converge
with Maintenance Updates as VNE makes them generally available to its other
customers. Converge agrees to install in the recommend environments all
Maintenance Updates within a reasonable time following the date they are
provided by VNE, taking into consideration any testing and customization
required by Converge (the parties expect that the time for such installation

                                        5
<PAGE>

generally will not exceed 90 days). Should Converge find one or more material
deficiencies in any Maintenance Update, Converge shall promptly identify such
deficiencies to VNE in reasonable detail.

            2.11 Method of Delivery. VNE will transfer to Converge all
Maintenance Updates, and any associated Documentation, by remote
telecommunications from the VNE place of business, to a Converge computer
located at a Converge place of business in the Commonwealth of Massachusetts, if
any. If any such Maintenance Update and/or associated Documentation cannot be
delivered via remote telecommunications to a Converge computer located at a
Converge place of business in the Commonwealth of Massachusetts, such
Maintenance Update and/or Documentation will be installed by VNE on a Converge
computer located at a Converge place of business in the Commonwealth of
Massachusetts, if any. Converge will not obtain title or possession of any
tangible personal property, including any storage media, as a result of the
delivery of any Maintenance Update or associated Documentation under this
Agreement.

            2.12 Acceptance. Each Maintenance Update will be deemed accepted by
Converge upon Converge's receipt of the complete delivery thereof to a Converge
computer located at a Converge place of business.

            2.13 License Rights. The scope of Converge's license rights to all
Maintenance Updates shall be as set forth in the Subscription License Agreement.
Except as may be set forth in the Subscription License Agreement, Converge
acknowledges and agrees that Vert has no obligation to deliver Source Code for
any Maintenance Update, or to grant Converge any license to use the Source Code
form of any Maintenance Update.

            2.14 Tracking of Maintenance Updates. VNE will maintain procedures
and systems designed to ensure that all Maintenance Updates are compatible with
previous versions of the Supported Products and any previously provided
Maintenance Updates and Enhancements.

            2.15 Modifications by Converge. Converge may notify VNE at least 10
Business Days in advance, through the Problem reporting process above, of
Converge's desire to modify any Supported Product, or the hardware and other
application and system software environment for any Supported Product. Within 10
Business Days of VNE's receipt of Converge's written notice, VNE will provide
Converge with any recommendations that VNE may have as to how Converge should
implement the desired modification. VNE shall have no responsibility for any
Problems, Errors or other issues with respect to the Supported Products that are
due to Converge's failure to ask for or follow any such recommendations of VNE.

      3. Professional Services.

            3.1 Project Managers. Each of Converge and VNE shall appoint a
Project Manager to coordinate such party's activities with respect to the
Professional Services hereunder. The initial VNE Project Manager shall be
Michael Decker and the initial Converge Project Manager shall be Farooq Ahmad.
Either party may change its Project Manager on notice (via e-mail or in some
other reasonable fashion not necessarily in accordance with the express notice

                                        6
<PAGE>

provisions of this Agreement) to the other party's Project Manager and
Relationship Manager at any time.

            3.2 Monthly Work Plans. As reasonably requested by either party, the
Converge Project Manager and the VNE Project Manager will conduct planning
meetings to determine the Professional Services that VNE will provide to
Converge for each month during the Term. In connection with each such planning
meeting, the Converge Project Manager and the VNE Project Manager will jointly
prepare a written work summary or plan (each, a "Work Plan") indicating the
Professional Services to be performed by VNE for such month. The Work Plan shall
identify those Professional Services that the Project Managers anticipate can be
performed without causing VNE to materially exceed (on a pro-rata monthly basis
for the given quarter, unless otherwise mutually agreed upon in writing) the
Quarterly Allocation for any quarter during the Term. All Professional Services
that the Project Managers anticipate will cause VNE to materially exceed (on a
pro-rata monthly basis for the given quarter, unless otherwise mutually agreed
upon in writing) the Quarterly Allocation shall either be separately identified
in the applicable Work Plan or performed by VNE pursuant to a Statement of Work
prepared in accordance with the following provisions of this Section 3. The
Converge Project Manager and the VNE Project Manager may amend any Work Plan
upon their written agreement at any time.

            3.3 Training to Converge. VNE will provide, and the Work Plans will
encompass as appropriate, VNE providing reasonable training and available
training materials to enable Converge to provide Level 1 support for the
Supported Products ("Support Training"). Support Training will include both
introductory training reasonably in advance of when new Supported Products are
put into production by Converge and periodic refreshers as appropriate when
Maintenance Updates and Vert-General Release Enhancements are released. Support
Training will be provided at mutually agreed locations and times.

            3.4 Environment and Deployment Process. As part of the Professional
Services provided by VNE, VNE will create a document entitled, "Environment and
Deployment Process." This document will detail the recommended Supported Product
environments and the build and deployment process for the Supported Products.
VNE agrees to complete a draft of this document for Converge's review within 30
days following the Effective Date. Converge agrees to review and provide final
comments on this draft document within 30 days after receipt thereof. Both
parties shall use commercially reasonable efforts to reach a mutual agreement on
the document and execute the final document within 90 days following the
Effective Date.

            3.5 Initial Request and Response. If Converge desires that VNE
perform any Professional Services that the Project Managers anticipate would
cause VNE to materially exceed (on a pro-rata monthly basis for the given
quarter, unless otherwise mutually agreed upon in writing) the Quarterly
Allocation, Converge shall submit to VNE a written request for such Professional
Services, which request shall detail the Professional Services being requested
in reasonable detail. Within 45 days after VNE's receipt of Converge's request
for VNE to perform any such Professional Services, VNE shall furnish to Converge
a preliminary statement of work (including proposed pricing, which shall take
into account any portion of such work that will be covered by a portion of the
Quarterly Allocation) under which VNE would be willing to perform such
Professional Services for Converge (each, a "Proposed SOW"). VNE may respond to

                                        7
<PAGE>

separate requests for Professional Services in a single Proposed SOW; provided,
however, that the Proposed SOW will itemize the foregoing information separately
for each of the requested Professional Services.

            3.6 Finalization of Proposed SOWs. If Converge desires to have VNE
provide any Professional Services under the terms of a Proposed SOW, Converge
shall notify VNE thereof in writing. Should Converge wish to negotiate the terms
of the Proposed SOW, the Converge Project Manager and the VNE Project Manager
shall promptly and in good faith discuss and agree upon what revisions, if any,
should be made to the Proposed SOW. Should the Converge Project Manager and the
VNE Project Manager reach mutual agreement on such revisions, if any, the
Proposed SOW shall be finalized and executed by both parties in writing (each, a
"Final SOW").

            3.7 Change Orders. Either party may request changes to a previously
agreed upon Final SOW. In such event, VNE will inform Converge the impact of
such changes. Changes to any Final SOW will be specified in a written change
order or amendment to the Final SOW. Neither party shall be bound by any change
order or amendment to a Final SOW unless and until such change order or
amendment has been executed by both parties in writing.

            3.8 Implementation. VNE will use commercially reasonable efforts to
perform all Professional Services covered by a Work Plan or Final SOW in
accordance with the schedule for performance of such Services set forth therein
(or within a reasonable time, with due regard for the consequences of delayed
performance, if no such schedule is set forth). Converge will reasonably
cooperate with VNE in connection with its performance of such Professional
Services as specified in the corresponding Work Plan or Final SOW and as may
otherwise be reasonably requested by VNE. VNE shall not be liable for any
default or delay in performance of such Professional Services to the extent the
same is attributable to the failure of Converge to comply in any material
respect with its obligations under this Agreement or any Work Plan or Final SOW.

            3.9 Method of Delivery. VNE will transfer to Converge all
Converge-Requested Enhancements to Converge, and any associated Documentation,
by remote telecommunications from the VNE place of business, to a Converge
computer located at a Converge place of business in the Commonwealth of
Massachusetts, if any. If any such Converge-Requested Enhancement and/or
associated Documentation cannot be delivered via remote telecommunications to a
Converge computer located at a Converge place of business in the Commonwealth of
Massachusetts, such Enhancement and/or Documentation will be installed by VNE on
a Converge computer located at a Converge place of business in the Commonwealth
of Massachusetts, if any. Converge will not obtain title or possession of any
tangible personal property, including any storage media, as a result of the
delivery of any Converge-Requested Enhancement or associated Documentation under
this Agreement.

            3.10 Acceptance. Each Converge-Requested Enhancement provided to
Converge under a Final SOW will be subject to acceptance testing by Converge in
accordance with the provisions of its corresponding Final SOW. All other
Converge-Requested Enhancements provided to Converge under this Agreement will
be deemed accepted by

                                        8
<PAGE>

Converge upon Converge's receipt of the complete delivery thereof to a Converge
computer located at a Converge place of business.

            3.11 Ownership; License to Vert. Unless otherwise expressly stated
in an applicable Work Plan or Final SOW, Vert shall be the sole and exclusive
owner of all Converge-Requested Enhancements, but excluding any portions thereof
that are or were developed independently by Converge or its Affiliates
("Converge-Independent Materials") and any portions thereof that are Converge
Brand Features or Third-Party Materials. Except as the parties may otherwise
agree in writing, Converge, to the extent it has the legal right to do so,
hereby grants to Vert an irrevocable, perpetual, world-wide, non-exclusive right
and license to use, load, store, transmit, execute, copy, market, distribute, in
any medium or distribution technology whatsoever, known or unknown, display,
perform and sublicense the Converge-Independent Materials and the Third-Party
Materials, in both Source Code and Object Code formats, and to make unlimited
instantiations thereof, for any and all purposes. As used herein, "Converge
Brand Features" means all logos, trademarks, service marks and trade names,
brand names and other brand features of Converge and its licensors (other than
Vert). As used herein, "Third-Party Materials" means any products or materials
of third parties (including Converge's licensors and third-party contractors) to
be incorporated into or provided as part of any Converge-Requested Enhancement.
Converge shall use reasonable efforts to identify to VNE all relevant
Third-Party Materials in the applicable Work Plan or Final SOW.

            3.12 License Rights of Converge. The scope of Converge's license
rights to each Converge-Requested Enhancement shall be as set forth in the
Subscription License Agreement and, if relevant, the applicable Final SOW.
Except as may be set forth in the Subscription License Agreement or as the
parties may otherwise expressly agree in writing, Converge acknowledges and
agrees that Vert has no obligation to deliver Source Code for any
Converge-Requested Enhancement, or to grant Converge any license to use the
Source Code form of any Converge-Requested Enhancement.

            3.13 Installation and Configuration. Converge shall be responsible
for installing and configuring any Converge-Requested Enhancements provided by
VNE hereunder. Converge may request, and VNE will provide, reasonable assistance
to Converge in its efforts to install and configure such Enhancements as part of
the Professional Services provided hereunder.

            3.14 Third-Party Technology. Except as the parties may otherwise
expressly agree in writing, Converge shall be responsible for paying for and,
with VNE's assistance, securing license rights to any third-party technology
required for the provision or use of any Converge-Requested Enhancements
provided under this Agreement. Vert shall use reasonable efforts to identify to
Converge all required license rights to third-party technology in the applicable
Work Plan or Final SOW.

            3.15 Unforseen Costs and Expenses. Notwithstanding anything to the
contrary in this Section 3, neither party shall be obligated to incur any costs
or expenses in connection with the performance or implementation of a Work Plan
or Final SOW unless such Work Plan or Final SOW reasonably contemplates that
such party shall be responsible for such costs or expenses, or such party
otherwise agrees in writing to incur such costs and expenses.

                                        9

            3.16 Escalation Procedures. Should the Converge Project Manager and
the VNE Project Manager be unable to reach agreement on any matter within the
scope of their discretion under this Section 3, the matter shall be escalated to
the parties' respective Relationship Managers for discussion. In addition,
should either party believe that the other party has failed to fulfill its
obligations under Section 2 or this Section 3 above, the matter shall be
escalated to the parties' respective Relationship Managers for discussion. The
initial VNE Relationship Manager shall be William Swank and the initial Converge
Relationship Manager shall be Francesco DeMarchis. Either party may change its
Relationship Manager on notice (via e-mail or in some other reasonable fashion
not necessarily in accordance with the express notice provisions of this
Agreement) to the other party's Project Manager and Relationship Manager at any
time, except that the Relationship Manager always shall be at the director level
or higher.

      4. Fees and Payments.

            4.1 Minimum Fee During Initial Term. Converge shall pay to VNE a
minimum fee of Four and One-Half Million Dollars ($4,500,000) for VNE's
provision of the Services during the Initial Term (the "Initial Term Minimum
Fee"). Converge shall pay the Initial Term Minimum Fee to VNE in 18 equal
installments of Two Hundred Fifty Thousand Dollars ($250,000) (each, a "Monthly
Installment"). Converge shall pay the first such Monthly Installment to VNE on
the date this Agreement is executed and delivered by both parties. Thereafter,
Converge shall pay each such Monthly Installment to VNE no later than the first
day of each month during the Initial Term (November 2001 and through March
2003). All such Monthly Installments are non-refundable.

            4.2 Minimum Fee During Each Renewal Term. If the Parties mutually
agree in writing to renew this Agreement pursuant to Section 9.1, the minimum
fee payable by Converge to VNE during any such renewal period shall be as
mutually determined by the Parties.

            4.3 Application of Quarterly Allocation; Out-Of-Scope Services. For
each quarter during the Term of this Agreement that Converge pays the applicable
Monthly Installments, Converge shall be entitled to receive Services in an
amount equal to the Quarterly Allocation; provided, however, that VNE shall
provide all Maintenance and Support Services with respect to Problem Reports
(but not with respect to Support Requests) reported during such quarter, and all
Maintenance Updates released by VNE during such quarter, regardless of whether
the provision of such Services would cause VNE to exceed the Quarterly
Allocation for such quarter; and provided further, however, that if Converge
fails to make a Monthly Installment when due (subject to the cure period in
Section 9.2(c)), VNE shall not be required to provided additional Services
during the remaining portion of the applicable quarter until such payment is
made. Should Converge request and VNE provide any Professional Services, or any
Maintenance and Support Services with respect to Support Requests, that would
cause VNE to exceed the Quarterly Allocation for any quarter, then Converge
shall pay VNE's then-current time charges, or such other charges as the parties
may otherwise agree in any Final SOW ("Out-Of-Scope Services"), for such
Out-Of-Scope Services. VNE shall use commercially reasonable efforts to inform
Converge that any Professional Services requested by Converge would be
Out-Of-Scope Services prior to VNE's performance of such Professional Services.
Converge shall not be required to pay for and VNS shall not be required to
perform any such Services that have not been approved in a Work Plan or Final
SOW, or otherwise approved by Converge in writing.

                                       10
<PAGE>

            4.4 Materials Costs and Expenses. Converge will reimburse VNE for
all reasonable materials costs and expenses actually incurred by VNE in
providing the Services under this Agreement, including travel and related
expenses; provided, however, that VNE shall bear any travel or related expenses
incurred by VNE at its sole option or as may be required in connection with the
correction of any Error. Notwithstanding the foregoing, if travel is required
due to the unavailability of remote access (see Section 2.9), then Converge
shall reimburse VNE for the reasonable costs of such travel and related
expenses. Upon Converge's request, the parties shall prepare budgets of any
materials costs and expenses to be incurred by VNE in its performance of any
Professional Services hereunder and any costs or expenses in excess of the
applicable budgeted amounts shall be subject to Converge's written approval,
such approval not to be unreasonably withheld or delayed. VNE's invoices for all
travel and related expenses shall be reasonably itemized and list all such
expenses by category/person/trip, and be accompanied by reasonable documentation
sufficient to support the deductibility by Converge of the reimbursable expense.

            4.5 Invoicing and Payments. Converge shall pay the Monthly
Installments to VNE on the dates specified in Section 4.1 and, if applicable,
Section 4.2 above. All other amounts due under this Agreement will be invoiced
by VNE to Converge on a monthly basis in arrears. All such invoiced amounts
shall be due to VNE within 30 days following Converge's receipt of VNE's
invoice. All payments will be made by Converge in U.S. dollars, without setoff,
recoupment or deduction. All fees and other amounts 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.

            4.6 Taxes. 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,
delivery of the Services under this Agreement, or Converge's or its Affiliates'
use thereof. In those jurisdictions in which VNE determines it is required to
register, collect and remit Sales Taxes, VNE will separately invoice Converge
for such Sales Taxes (which invoices shall be payable by Converge as set forth
in Section 4.5), collect such Sales Taxes from Converge and remit such Sales
Taxes to the proper taxing authority. In those jurisdictions in which VNE 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). Subject to the express provisions
of this Agreement, the parties will cooperate and use their commercially
reasonable efforts to minimize or avoid, to the maximum extent allowed by law,
the obligation to pay any Sales Taxes that may be levied on payments made under
this Agreement or otherwise are chargeable by any applicable government
authority with respect to the Services.

            4.7 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

                                       11
<PAGE>

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 VNE 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 VNE 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 VNE so that VNE
receives, net of withholding taxes, the amounts VNE would have received if
Converge had not substituted a foreign person or had remained a domestic person.

      5. Warranty.

            5.1 Services Warranty. VNE warrants that the Services provided
hereunder will be provided in accordance with generally-accepted industry
standards applicable to the performance of services of a similar nature. In the
event of any breach of the foregoing warranty, and provided that Converge
reports such breach to VNE in writing within 90 days following the date of
performance of the Services in question, VNE shall, as its sole obligation and
Converge's sole and exclusive remedy, promptly repair, replace or re-perform the
Services in question, without additional cost to Converge, so as to correct the
warranty non-compliance as promptly as practicable (within 30 days to the extent
technically feasible).

            5.2 Disclaimer. WITH THE EXCEPTION OF THE EXPRESS WARRANTY PROVIDED
IN SECTION 5.1 AND AS THE PARTIES MAY OTHERWISE AGREE IN ANY WORK PLAN, VNI AND
ALL AFFILIATES OF VNI SPECIFICALLY DISCLAIM ANY AND ALL WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY,
ACCURACY, FITNESS FOR A PARTICULAR PURPOSE, QUIET ENJOYMENT AND NON-INFRINGEMENT
OF THIRD PARTY RIGHTS RELATING TO ANY SERVICES, MAINTENANCE UPDATES OR
ENHANCEMENTS PROVIDED OR TO BE PROVIDED HEREUNDER.

      6. Limitation of Liability.

            6.1 Disclaimer of Liability for Certain Damages.

                  6.1.1 Consequential and Similar Damages. TO THE MAXIMUM EXTENT
PERMITTED BY LAW, IN NO EVENT SHALL EITHER PARTY BE LIABLE OR OBLIGATED IN ANY
MANNER FOR ANY SPECIAL, INCIDENTAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES OF ANY
KIND ARISING OUT OF OR RELATING TO THIS AGREEMENT (INCLUDING, BUT NOT LIMITED
TO, LOST PROFITS, REVENUES OR BUSINESS OPPORTUNITIES) HOWEVER CAUSED AND
REGARDLESS OF THE FORM OF ACTION, WHETHER IN CONTRACT, TORT, NEGLIGENCE, STRICT
PRODUCT LIABILITY, OR OTHERWISE, EVEN IF THE PARTY HAS BEEN INFORMED OF THE
POSSIBILITY OF ANY SUCH DAMAGES IN ADVANCE. The foregoing limitation

                                       12
<PAGE>

is independent of any exclusive remedies available to either party under this
Agreement, including any failure of such remedies.

                  6.1.2 Loss of Data, Usage, Etc. VERT DOES NOT GUARANTEE THAT
ANY MAINTENANCE UPDATES OR ENHANCEMENTS WILL 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 ANY PRODUCTS, MAINTENANCE UPDATES
OR ENHANCEMENTS RESULTING THEREFROM.

            6.2 Sole Remedy. IF A CLAIM OR CAUSE OF ACTION IS ATTRIBUTABLE TO
ANY MAINTENANCE UPDATE, ENHANCEMENT OR SERVICES PROVIDED OR TO BE PROVIDED UNDER
THIS AGREEMENT, THE REMEDIES SET FORTH IN THIS AGREEMENT, TO THE EXCLUSION OF
THE REMEDIES SET FORTH IN THE SUBSCRIPTION LICENSE AGREEMENT, SHALL CONSTITUTE
THE SOLE AND EXCLUSIVE REMEDIES AVAILABLE TO A PARTY FOR SUCH CLAIM OR CAUSE OF
ACTION. IF A CLAIM OR CAUSE OF ACTION IS ATTRIBUTABLE TO A PRODUCT OR ANY
SERVICES PROVIDED UNDER THE SUBSCRIPTION LICENSE AGREEMENT, THE REMEDIES SET
FORTH IN THE SUBSCRIPTION LICENSE AGREEMENT, TO THE EXCLUSION OF THE REMEDIES
SET FORTH IN THIS AGREEMENT, SHALL CONSTITUTE THE SOLE AND EXCLUSIVE REMEDIES
AVAILABLE TO A PARTY FOR SUCH CLAIM OR CAUSE OF ACTION. For the sake of clarity,
the parties acknowledge that claims concerning Vert's ownership of and
Converge's license rights to any Maintenance Updates, Enhancements or associated
Documentation shall be deemed to have arisen under the Subscription License
Agreement, that claims with respect to VNE's delivery of any Vert-General
Release Enhancements or associated Documentation, or the performance or
non-performance of any Vert-General Release Enhancements, shall be deemed to
have arisen under the Subscription License Agreement, and that claims with
respect to VNE's delivery of any Maintenance Updates, Converge-Requested
Enhancements or associated Documentation, or the performance or non-performance
of any Maintenance Updates or Converge-Requested Enhancements, shall be deemed
to have arisen under this Agreement. NO LIABILITY SHALL EXTEND UNDER THIS
AGREEMENT TO ANY THIRD PARTY (INCLUDING, BUT NOT LIMITED TO, ANY AFFILIATES OF
VNI OTHER THAN VNE, OR THEIR LICENSORS) IF NOT INVOLVED IN THE DEVELOPMENT OR
DELIVERY OF ANY MAINTENANCE UPDATE, ENHANCEMENT OR SERVICES HEREUNDER.

            6.3 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
DAMAGES, IF ANY, RELATING TO THIS AGREEMENT OR ANY MAINTENANCE UPDATE,
ENHANCEMENT OR SERVICES PROVIDED OR TO BE PROVIDED HEREUNDER, WHETHER FOR BREACH
OF CONTRACT OR WARRANTY, STRICT LIABILITY, NEGLIGENCE OR OTHER TORT, STRICT
PRODUCT LIABILITY, THE FAILURE OF ANY LIMITED REMEDY TO ACHIEVE ITS ESSENTIAL
PURPOSE, OR OTHERWISE, SHALL NOT EXCEED (I) WITH RESPECT TO ANY ENHANCEMENT
PROVIDED HEREUNDER, THE AMOUNTS PAID BY CONVERGE TO VERT FOR SUCH ENHANCEMENT,
AND (II) WITH RESPECT TO ANY MAINTENANCE AND SUPPORT SERVICES, THE AMOUNTS PAID
BY

                                       13
<PAGE>

CONVERGE TO VERT FOR SUCH MAINTENANCE AND SUPPORT SERVICES DURING THE THREE
MONTH PERIOD IMMEDIATELY PRECEDING THE DATE ON WHICH THE CLAIM OR CAUSE OF
ACTION FOR ANY SUCH DAMAGES FIRST AROSE. THE FOREGOING LIMITATIONS ON EACH
PARTY'S AGGREGATE LIABILITY TO THE OTHER SHALL BE IN ADDITION TO ANY FEES AND
OTHER AMOUNTS DUE AND OWING UNDER SECTION 4. FOR PURPOSES OF THIS SECTION 6.3,
THE TERM "PARTY" MEANS CONVERGE ON THE ONE HAND, AND VNI AND VNE COLLECTIVELY ON
THE OTHER HAND, SO THAT AS TO VNI AND VNE THE LIMITATIONS IN THIS SECTION 6.3
ARE COLLECTIVE LIMITATIONS AND NOT SEPARATE LIMITATIONS FOR EACH OF VNI AND VNE.

            6.4 Exceptions. THE LIMITATIONS OF LIABILITY CONTAINED IN THIS
SECTION 6 SHALL NOT APPLY WITH RESPECT TO (A) ANY CLAIMS OF BODILY INJURY OR
DAMAGE TO TANGIBLE PERSONAL PROPERTY RESULTING FROM WILLFUL MISCONDUCT OR GROSS
NEGLIGENCE, (B) ANY BREACH OF THE CONFIDENTIALITY OBLIGATIONS IN SECTION 7, OR
(C) LIABILITY FOR PAYMENT OF INTEREST ADDED BY A COURT OF LAW OR AN ARBITRATION
PANEL TO A JUDGMENT ENTERED IN ANY ACTION OR PROCEEDING UNDER THIS AGREEMENT.

            6.5 Duty to Mitigate. Each party will have a duty to take reasonable
steps to mitigate damages for which the other party is responsible.

            6.6 Acknowledgement. Each of the parties acknowledge that the
disclaimers and limitations set forth in this Section 6 are an essential element
of this Agreement between the parties and that the parties would not have
entered into this Agreement without such disclaimers and limitations.

      7. Confidential Information.

            7.1 Definition of Confidential Information. "Confidential
Information" as used in this Agreement shall mean any and all proprietary or
non-public information of a party 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.

            7.2 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

                                       14
<PAGE>

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.

            7.3 Exclusions from Nondisclosure and Nonuse Obligations. The
obligations under this Section 7 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.

            7.4 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 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.

      8. Non-Solicitation. During the Term of this Agreement and for a period of
one year thereafter, Converge and Vert each agree not to directly or indirectly
solicit, encourage or cause others to solicit or encourage any employees or
individual independent contractors of the other party to terminate their
employment or independent contracting relationship with the other party and
become an employee or independent contractor of the soliciting party or its
Affiliate. This provision does not prohibit a party's responding to unsolicited
employment inquiries and/or any

                                       15
<PAGE>

indirect solicitations and other employment activities (e.g., job postings,
advertising of positions) that are not specifically targeted at any particular
individual.

      9. Term; Events of Default; and Termination.

            9.1 Term. The initial period of this Agreement (the "Initial Term")
shall commence upon the Effective Date and continue until March 31, 2003.
Thereafter, this Agreement shall renew only upon the mutual written agreement of
the parties for up to three additional renewal terms of one year each (each, a
"Renewal Term"). Notwithstanding the foregoing provisions of this Section 9.1,
in the event any Services or other obligations of either party (including
payment obligations) with respect to any Final Work Plan have not been completed
or discharged as of the date on which this Agreement would otherwise expire,
this Agreement shall remain in effect solely with respect to such Work Plan
until such Services or other obligations have been completed or discharged.

            9.2 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 and the
result is 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 30 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 30-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 60th 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 30-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 4 and fails to cure such
breach within 3 Business Days after VNE gives Converge written notice specifying
the breach.

            9.3 Termination. Immediately upon the occurrence of an Event of
Default by either party, the other party shall have the right, but not the
obligation, to terminate this Agreement, exercisable by such other party giving
written notice thereof to first party within 10 Business Days after the
occurrence of such Event of Default. In addition, this Agreement shall
automatically terminate upon any termination of the Subscription License
Agreement as permitted thereunder.

            9.4 Effect of Termination. Upon the expiration or termination of
this Agreement, each party shall erase, destroy or return to the other party all
copies of the Confidential Information of or provided by such party under this
Agreement and, upon such other party's written request, shall certify its
compliance with this Section 9.4 to the other party in writing. Notwithstanding
the foregoing provisions of this Section 9.4, with respect to and for so long as
any licenses granted to Converge respecting Deployed Products and/or Source Code
under the Subscription License Agreement survive the expiration or termination
of this

                                       16
<PAGE>

Agreement, Converge shall not be required to erase, destroy or return any
Confidential Information of Vert or its Affiliates respecting such Deployed
Products and/or Source Code.

            9.5 Effect of Vert Non-Renewal Election. If VNE or VNI is unwilling
to renew this Agreement on its existing terms for any Renewal Term, a "Vert
Non-Renewal Election" shall be deemed to have occurred. In the event of a
Vert-Non-Renewal Election, in addition to any rights or remedies that may be
available to Converge under the Subscription License Agreement, the provisions
of Section 8 above shall cease to apply with respect to Converge's solicitation
or encouragement of any of the VNE Service Personnel to terminate their
employment or independent contracting relationship with VNE and become an
employee or independent contractor of Converge or its Affiliate.

            9.6 Effect of Converge Non-Renewal Election. If VNE or VNI is
willing to renew this Agreement on its existing terms for any Renewal Term, but

                                    Exhibit A
                           Severity Levels of Problems

The following chart describes the distinctions between the different severity
levels for Problems reported by Converge.

<TABLE>
<CAPTION>
Severity    Definition
Level
<S>         <C>
1           A "Severity Level 1" Problem is one where critical or central
            functionality of the Supported Product is unavailable and the
            Supported Product cannot reasonably be used, or performance of
            critical or central functionality of the Supported Product is
            severely degraded, and in either such case Converge does not have or
            cannot implement a reasonable workaround. 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, in each case
            without Converge being able to implement a reasonable workaround:

            -     Data is corrupted or lost by the Supported Product, or the
                  Supported Product returns incorrect results, and such
                  corruption, loss or incorrect results have a material adverse
                  impact on critical or central functionality of the Supported
                  Product
            -     Complete or severe lack of ability to use the critical or
                  central functionality of the Supported Product
            -     The Supported Product crashes repeatedly
            -     Critical or central functionality of the Supported Product is
                  not operational or is severely degraded
            -     Critical or central functionality of the Supported Product
                  fails to run to completion

2           A "Severity Level 2" Problem is one where critical or central
            functionality of the Supported Product is unavailable, or
            performance of critical or central functionality of the Supported
            Product is severely degraded, but in either such case Converge can
            implement a reasonable workaround but such workaround does not
            downgrade the Problem to Severity Level 3 or 4. Use of critical or
            central functionality of the Supported Product can continue in a
            restricted fashion through use of such workaround, but the user
            still experiences a significant degradation of performance of such
            functionality. A "Severity Level 2" Problem may have one or more of
            the characteristics of a "Severity Level 1" Problem, but critical or
            central functionality of

            -     the Supported Product can continue to operate in a restricted
                  fashion through use of such workaround.

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. A "Severity Level 3" Problem may have one
            or more of the following characteristics:

            -     Performance of the Supported Product is degraded in a
                  non-critical manner
            -     Performance of the Supported Product is minimally impaired

<TABLE>
<S>         <C>
4           A "Severity Level 4" Problem causes no loss of use of the Supported
            Product. The following would be "Severity Level 4" Problems:

            -     Cosmetic problem with the Supported Product
            -     Documentation error
            -     Minor incorrect behavior of the Supported Product that does
                  not impede its operation
