                                  THE TRANSFER

The date on which the Closing shall occur is referred to herein as the "CLOSING

limited liability company to take, and will take, all such lawful and necessary
action.

                                   ARTICLE 3.

                             POST CLOSING ADJUSTMENT

         3.1. Definitions. For the purposes of this Article 3, the following
definitions shall apply:

         (a) "CLOSING DATE NET BOOK VALUE" shall be an amount, calculated as set
             forth in the Closing Schedules, equal to (i) the sum of the
             Company's total member's capital and intercompany debt, each as of
             the Closing Date, plus (ii) the sum of the Company's goodwill
             amortization expense, other intangible amortization expense and
             depreciation expense during the period beginning November 1, 2000
             and ending on the Closing Date.

         (b) "CLOSING DATE NET WORKING CAPITAL" shall be an amount, calculated
             as set forth in the Closing Schedules, equal to the sum of (i) the
             Company's current assets, less current liabilities (excluding
             intercompany debt), each as of the Closing Date, plus (ii) the
             Company's cumulative capital expenditures during the period
             beginning November 1, 2000 and ending on the Closing Date.

         (c) "BALANCE SHEET DATE NET BOOK VALUE" shall be an amount, calculated
             as set forth on Schedule 3.1(c), equal to the sum of the Company's

<PAGE>   5
         (d) "BALANCE SHEET DATE NET WORKING CAPITAL" shall be an amount,
             calculated as set forth on Schedule 3.1(d), equal to the sum of the
             Company's current assets, less current liabilities (excluding
             intercompany debt), each as of the Balance Sheet Date.

         3.2. Post-Closing Audit. Converge shall cause Converge's auditors to
conduct an audit of the Company to the extent necessary to determine whether any
adjustment to the Cash Consideration would be required pursuant to Section 3.4
below (the "POST-CLOSING AUDIT"), which audit shall be completed within 60 days
after the Closing Date. Converge's auditors shall have reasonable access to, and
the right to review, the Books and Records of the Company necessary for
conducting the Post-Closing Audit. Upon completion of the Post-Closing Audit,
Converge's auditors shall deliver an audited consolidated balance sheet of the
Company as of the Closing Date (the "AUDITED CLOSING DATE CONSOLIDATED BALANCE
SHEET") to Converge and VerticalNet. Separate Closing schedules setting forth
the calculation of the Closing Date Net Working Capital and Closing Date Net
Book Value (the "CLOSING SCHEDULES"), shall be prepared by Converge's Director
of Finance and delivered to VerticalNet in conjunction with the audited results.
Converge shall cause Converge's auditors to give VerticalNet and VerticalNet's
auditors reasonable access to the work papers of Converge's auditors related to
the Post-Closing Audit.

         3.3 Disputes. The Audited Closing Date Balance Sheet and the Closing
Schedules shall be deemed final and binding upon VerticalNet for the purposes of
determining whether any adjustment of the Cash Consideration would be required
pursuant to Section 3.4 below unless VerticalNet shall have delivered, within 10
Business Days following VerticalNet's receipt of the Audited Closing Date
Consolidated Balance Sheet and the Closing Schedules, a written notice (the
"DISPUTE NOTICE") to Converge. The Dispute Notice shall set forth the items in
the Audited Closing Date Consolidated Balance Sheet and the Closing Schedules
that either VerticalNet or VerticalNet's auditors dispute as not being in
accordance with the requirements of this Agreement or as having computational
errors, specifying in reasonable detail the nature and extent of any such
disagreement, including the amount of any proposed decrease in the Deficiency
(defined in Section 3.4 below) that would result if such disagreement were
resolved in VerticalNet's favor. VerticalNet and Converge shall negotiate in
good faith to resolve any such disagreement. If, after a period of 10 Business
Days, VerticalNet and Converge shall not have resolved such disagreement,
Converge and VerticalNet shall engage Arthur Andersen LLP or, if such firm
refuses to accept such engagement on terms reasonably acceptable to Converge and
VerticalNet, another independent, nationally recognized auditing firm reasonably
acceptable to Converge and VerticalNet (the "INDEPENDENT AUDITOR"). Converge and
VerticalNet shall engage the Independent Auditor to decide such disagreement
within 60 days from its engagement. The decision of the Independent Auditor
shall be final and binding upon the Parties, and a declaratory judgment by a
court of competent jurisdiction may be entered in accordance therewith. The fees
and expenses of the Independent Auditor shall be borne equally by Converge and
VerticalNet.

         3.4 Adjustment.


                                      -4-
<PAGE>   6
         (a) If either (i) the Balance Sheet Date Net Working Capital exceeds
the Closing Date Net Working Capital or (ii) the Balance Sheet Date Net Book
Value exceeds the Closing Date Net Book Value, then the Cash Consideration shall
be decreased on a dollar-for-dollar basis by an amount (the "DEFICIENCY") equal
to the greater of (i) the difference between the Balance Sheet Date Net Working
Capital and the Closing Date Net Working Capital, or (ii) the difference between
the Balance Sheet Date Net Book Value and the Closing Date Net Book Value. No
increase in the Cash Consideration shall be made.

         (b) Within 15 Business Days of Converge's receipt of the Audited
Closing Date Consolidated Balance Sheet and the Closing Schedules, the following
payments shall be paid by wire transfer of immediately available funds:

                  (i) If the Deficiency is greater than the Holdback Amount,
         then Converge shall retain the entire Holdback Amount and VerticalNet
         shall pay to Converge an amount equal to the difference between the
         Deficiency and the Holdback Amount;

                  (ii) If the Deficiency is less than the Holdback Amount, then
         Converge shall retain an amount equal to the Deficiency from the
         Holdback Amount and pay to VerticalNet an amount equal to the
         difference between the Holdback Amount and the Deficiency; or

                  (iii) If there is no Deficiency, then Converge shall pay to
         VerticalNet the entire Holdback Amount;

provided, however, that if any disagreement with respect to the Audited Closing
Date Consolidated Balance Sheet or the Closing Schedules remains unresolved as
of the date of payment under this Section 3.4(b), then a portion of any amounts
to be paid to VerticalNet equal to the amount of any proposed decrease in the
Deficiency set forth in the Dispute Notice shall continue to be held by Converge
until the final resolution of such disagreement between the Parties in
accordance with Section 3.4 above.

         3.5 Exclusive Remedy. To the extent that any fact or circumstance shall
have resulted in a decrease in the Cash Consideration, the actual decrease
resulting from of such fact or circumstance shall not provide the basis for a
claim of indemnification under Article 11.

                                   ARTICLE 4.

the subject of bankruptcy, conservatorship or rehabilitation proceedings.

         (j) No Acceleration or Creation of Rights. Except as set forth in
Section 4.19(j) of APPENDIX II, neither the execution and delivery of this

creation of any rights of any person to benefits under any Employee Plan
(including the acceleration of the vesting or exercisability of any stock
options, the acceleration of the vesting of any restricted stock, the
acceleration of the accrual or vesting of any benefits under any Pension Plan or

         time or the taking of any action (or failure to take any action) by or

         as described in Section 4.22(d) of APPENDIX II, the Company has no
         knowledge that the Company or any employee thereof either is or was
         under any obligation of noncompetition, secrecy, confidentiality or
         non-disclosure to any third party with respect to any Software Product.

                  (vii) To the Company's knowledge, any customized software

APPENDIX II, the Company and VerticalNet (i) have not received any notice
alleging, or otherwise have knowledge of facts that might give rise to,
invalidity or unenforceability with respect to any of the Proprietary Rights of
the Company and (ii) have not received any notice of alleged infringement of any
rights of others due to any activity by the Company. To the Company's knowledge,
the Company's use of its Proprietary Rights in its past and current products and
services does not infringe upon or otherwise violate the valid rights of any
third party anywhere in the world. No other Person (i) has notified the Company
or VerticalNet that it is claiming any ownership of or right to use any of the
Company's Proprietary Rights or (ii) to the Company's knowledge, is infringing
upon any such Proprietary Rights in any way.

         (g) Protection of Confidential Proprietary Rights. The Company has

WRITTEN AGREEMENT ENTERED INTO BY ANY OF THE PARTIES WITH RESPECT TO ANY ASSET
OF THE COMPANY, BUT, IN SUCH EVENT, ONLY TO THE EXTENT AS SET FORTH THEREIN WITH
RESPECT TO THE SUBJECT MATTER THEREOF.

                                   ARTICLE 5.

                   MATTERS RELATING TO THE STOCK CONSIDERATION

         5.1 Purchase Entirely for Own Account. The Stock Consideration is being
issued to VNI Holdings Inc., a wholly-owned subsidiary of VerticalNet ("VNI") in
reliance upon VerticalNet's representation to Converge, which by VerticalNet's
execution of this Agreement VerticalNet hereby confirms, that the Stock
Consideration to be issued to VNI (at the direction of VerticalNet) and the
Common Stock issuable upon conversion thereof (collectively, the "SECURITIES")
will be acquired for investment for VNI's own account, not as a nominee or agent
on behalf of any other Person, and not with a view to the resale or distribution
of any part thereof, and that neither VerticalNet or VNI has any present
intention of selling, granting any participation in, or otherwise distributing
same. By executing this Agreement, VerticalNet further represents that
VerticalNet has no Contract with any Person to sell, transfer or grant


                                      -25-
<PAGE>   27
participations to such Person or to any other Person, with respect to any of the
Securities, except as contemplated hereby.

         5.2 Disclosure of Information. Converge has provided VerticalNet the
opportunity to ask questions of Converge and has provided full access to its
facilities and personnel in response to any request therefor that VerticalNet,
has made, concerning Converge and its activities, and all other matters relating
to the operations of Converge and the offering and sale of shares of Stock
Consideration. The foregoing, however, does not limit or modify the
representations and warranties of Converge in Article 6 of this Agreement or the
right of VerticalNet to rely thereon.

         5.3 Investment Experience. VerticalNet, through VNI, is an investor in
securities of companies in the development stage and acknowledges that it is
able to fend for itself, can bear the economic risk of its investment, and has
such knowledge and experience in financial or business matters that it is
capable of evaluating the merits and risks of the investment in the Stock
Consideration. VerticalNet also represents VNI has not been organized for the
purpose of acquiring the Securities.

         5.4 Accredited Investor. VNI is an "accredited investor" within the
meaning of Rule 501 of Regulation D of the Securities Act, as presently in
effect.

         5.5 Restricted Securities. VerticalNet understands that the Securities
are characterized as "restricted securities" under the federal securities laws
inasmuch as they are being acquired from Converge in a transaction not involving
a public offering and that under such laws and applicable regulations such
securities may be resold without registration under the Securities Act, only in
certain limited circumstances. In this connection, VerticalNet represents that
it is familiar with Rule 144 of the Securities Act, as presently in effect, and
understands the resale limitations imposed thereby and by the Securities Act. In
addition, VerticalNet understands that the Investors Agreement, in the form
attached hereto as EXHIBIT A-1, contains additional restrictions on the
transferability of the Securities.

         6.15 Liabilities. Except as set forth in Section 6.15 of APPENDIX III,
Converge has no Liabilities which may reasonably be expected to result in a
Converge Material Adverse Effect except (i) Liabilities which are properly
accrued for in accordance with GAAP in the Converge Financial Statements, (ii)
Liabilities incurred in the ordinary course of business and consistent with past
practice since the Balance Sheet Date and (iii) Liabilities arising under the
Converge Material Contracts (other than obligations which are required to be
reflected on a balance sheet prepared in accordance with GAAP and Liabilities
relating to breach of contract) or Liabilities which are not required to be
disclosed on such Appendix and which have arisen or been incurred in the
ordinary course of business. Except as set forth in Section 6.15 of APPENDIX
III, none of the Liabilities described in this Section 6.15 relates to any
claim, suit, litigation, proceeding or investigation known to Converge
(collectively, "ACTIONS") or breach of Contract, breach of warranty, tort,
infringement or violation of any Regulation or arose out of any action, order,
writ, injunction, judgment or decree outstanding.

         6.16 Litigation. Except as set forth in Sections 6.16 of APPENDIX III,
there is no Action, pending or, threatened in writing (i) against, relating to
or affecting Converge, any of the material Assets or Converge's officers and
directors, in any of their capacity as such, (ii) which seeks to enjoin or
obtain damages in respect of the transactions contemplated hereby or by the


                                      -36-
<PAGE>   38
Ancillary Agreements or (iii) or anticipated which could reasonably be expected
to prevent Converge from consummating the transactions contemplated hereby.
Except as set forth in Section 6.16 of APPENDIX III, none of the Actions, if
adversely determined against Converge, its directors or officers, or any other
Person could reasonably be expected to result in a loss to Converge,
individually in excess of $25,000. To Converge's knowledge, there is no basis
for any Action, which (a) if adversely determined against Converge or (b) if
adversely determined against any officer or director, that could reasonably be
expected to cause Converge to incur an obligation to indemnify such officer or
director under Converge's Certificate of Incorporation or by statute, that
could, in each such case, be reasonably expected to result in a loss to Converge
in excess of $25,000. There are presently no outstanding Court Orders that would
impose upon Converge any material obligation in law or in equity. Section 6.16
of APPENDIX III contains a complete and accurate description of all Actions
since April 26, 2000 to which Converge or any predecessor of Converge has been a
party or, to Converge's knowledge, which otherwise relate to any of the material
Assets of Converge or Converge's officers or directors as such, or any such
Actions which were settled prior to the institution of formal proceedings. This
section does not apply to any Environmental Claims.

         6.17     Labor Matters.

         (a) General. Converge is not a party to any collective bargaining
agreement with respect to its Employees with any labor organization, group or
association and to Converge's knowledge has not experienced any attempt by
organized labor or its representatives to make Converge conform to demands of
organized labor relating to its Employees or to enter into a binding agreement
with organized labor that would cover the Employees of Converge. There is no
unfair labor practice charge or complaint against Converge pending before the
National Labor Relations Board (or its equivalent in any applicable
jurisdiction) or any other governmental agency arising out of Converge's
activities, there is no labor strike or labor disturbance pending or, to
Converge's knowledge, threatened against Converge nor has Converge received
notice that any grievance is currently being asserted against it; and Converge
has not experienced a work stoppage. There are no material controversies pending
or, to Converge's knowledge, threatened between Converge and its Employees.

         (b) Compliance. Converge is in material compliance with all applicable
Regulations respecting employment practices, terms and conditions of employment,
wages and hours, equal employment opportunity. Except as set forth in Section
6.17(b) of APPENDIX III, to Converge's knowledge, Converge is not liable for any
claims for any material amount of past due wages. Except as set forth in Section
6.17(b) of APPENDIX III, Converge is not liable for any penalties for failure to
comply with any of the foregoing.

         (c) Severance Obligations. Except as set forth in Section 6.17(c) of
APPENDIX III, Converge is not a party to any severance agreement, "stay-bonus"
agreement or similar arrangement, in each such case those currently in effect,
with any current or past executive officers or directors of Converge that will
result in any obligation (absolute or contingent) of Converge or that would
cause Converge to make any payment in excess of $25,000 to any such persons
following termination of employment or upon consummation of the transactions
contemplated by this Agreement (whether or not employment is continued for any
specified period after the Closing Date). Except as set forth in Section 6.17(c)
of APPENDIX III, neither


                                      -37-
<PAGE>   39
the execution and delivery of this Agreement or any Ancillary Agreement nor the
consummation of the transactions contemplated hereby or thereby will result in
the acceleration or vesting of any other rights of any Person to benefits under
any Employee Plans.

         6.18 Employee Benefit Plans. Section 6.18 of APPENDIX III contains a
complete list of Employee Plans which cover or have covered employees of
Converge or any predecessor (with respect to their relationship with Converge or
any predecessor). To the extent they exist, true and complete copies of each of
the following documents have been made available by Converge to VerticalNet: (i)
each Employee Plan document (and, if applicable, related trust agreements,
annuity contracts or other funding instruments) which covers or has covered
employees of Converge (with respect to their relationship with Converge) and all
amendments thereto, all summary plan descriptions, summary of material
modifications (as defined in ERISA) and all written interpretations and

forth the amount of any Liability of the Company as of the Closing Date for
payments more than 30 calendar days past due with respect to any Welfare Plan.

         funding instrument which covers or has covered employees or former
         employees of Converge (with respect to their relationship with
         Converge) which has been operated as a plan that is intended to be
         qualified under Section 401(a) of the Code (1) has received a favorable
         determination letter from the Internal Revenue Service stating that
         such Pension Plan and each related trust is qualified and tax-exempt

         appropriate) and 501(a) or still has a remaining period of time under
         applicable Treasury Regulations or IRS pronouncements in which to apply
         for such letter and to make any amendments necessary to obtain a
         favorable determination and (2) to the knowledge of Converge each
         Pension Plan has been so qualified during the period from its adoption
         to date, and nothing has occurred that is reasonably likely to
         adversely affect such qualification.

                  (ii) Each Pension Plan and each related trust agreement,
         annuity contract or other funding instrument which covers or has

         respects and has been maintained in compliance in all material respects
         with its terms and, both as to form and in operation, with the
         requirements prescribed by any and all statutes, orders, rules and
         regulations which are applicable to such plans, including ERISA and the

Code or Title IV of ERISA, nor have they any current or contingent obligation to
contribute to any Multiemployer Plan.

         (c)      Welfare Plans.

                  (i) Except as set forth in Section 6.18(c)(i) of APPENDIX III,
         each Welfare Plan which covers or has covered employees or former

         Company) complies in all material respects with its terms and, both as
         to form and operation, with the requirements prescribed by any and all
         statutes, orders, rules and regulations which are applicable to such
         Welfare Plan, including ERISA and the Code.

                   (ii) Except as set forth in Section 6.18(c)(ii) of APPENDIX
         III, each Welfare Plan that is a group health plan (within the meaning
         of Section 4980B(g)(2) of the Code) complies in all material respects
         in all material respects, and in each and every case has materially
         complied, with all of the applicable requirements of Section 4980B of

                   (iii) Except as set forth in Section 6.18(c)(iii) of APPENDIX
         III, no Welfare Plan provides any health, life or other welfare

         than coverage as may be required under Section 4980B of the Code or
         Part 6 of ERISA, or otherwise as a result of applicable laws.

                  (iv) Neither the Company nor any ERISA Affiliate has, at any

orders, rules and regulations.

         (e) Deductibility of Payments. There is no contract, agreement, plan or
arrangement covering any employee or former employee of Converge (with respect
to such employee's relationship with Converge) that, individually or
collectively, requires the payment by Converge of any amount (i) that is not
deductible under Section 162(a)(1) or 404 of the Code or (ii) that is an "excess

<PAGE>   41
         (f) Prohibited Transactions. There have not been any "prohibited
transactions," as such term is defined under Section 4975 of the Code or Section

Section 6.18(j) of APPENDIX II, neither the execution and delivery of this

THE ASSETS AND THE BUSINESS OF THE COMPANY BEING ACQUIRED AS A RESULT OF THIS
AGREEMENT SHALL BE DEEMED TO HAVE BEEN ACQUIRED ON AN "AS IS," "WHERE IS" BASIS

                                 INDEMNIFICATION

         11.1 Survival of Representations, etc. All statements contained in this
Agreement, any schedule or in any certificate or instrument of conveyance
delivered by or on behalf of the Parties pursuant to this Agreement or in
connection with the transactions contemplated hereby shall be deemed to be
representations and warranties by such Party hereunder. The representations and
warranties contained herein (and claims based upon or arising out of such
representations and warranties, as well as any claims based upon or arising out
of any covenants and agreements herein or made hereunder) may be asserted at any
time and shall survive the Closing Date until the relevant dates set forth in
Section 11.3(c). No investigation made by any of the Parties (whether prior to,
on or after the Closing Date) shall in any way limit the representations and
warranties of the Parties. On the Closing Date all representations and
warranties contained in this Agreement and made by the Company shall expire as
to the Company and thereafter will be deemed to have been made exclusively by
VerticalNet. The termination of the representations and warranties provided
herein shall not affect the rights of a Party in respect of any claim made by
such Party in a writing received by any other Party prior to the expiration of
the applicable survival period provided in Section 11.3(c).

         11.2     Indemnification.

         (a)      General.

                  (i) Subsequent to the Closing, VerticalNet shall, subject to
         the limitations contained in Sections 3.5 and 11.3, indemnify Converge,
         its Affiliates, and each of their respective, officers, directors,
         employees, stockholders and agents ("CONVERGE INDEMNIFIED PARTIES")
         against, and hold each of the Converge Indemnified Parties harmless
         from, any damage, claim, Encumbrance, loss, cost, Tax, Liability or
         expense (including interest, penalties, reasonable attorneys' fees and
         expenses of investigation), diminution of value, response action,
         removal action or remedial action (collectively "DAMAGES") sustained,
         suffered or incurred by any such Converge Indemnified Party, that arise
         out of or relate to, the breach of any warranty, representation,
         covenant or agreement of the Company or VerticalNet contained in this
         Agreement or any schedule hereto delivered by or on behalf of the
         Company or VerticalNet pursuant to this


                                      -54-
<PAGE>   56
         Agreement or in connection with the transactions contemplated hereby,
         net of any related insurance recoveries and any related reductions
         after Closing in the federal, state or local Liability of any Converge
         Indemnified Party or the Company for Taxes paid or payable during the
         tax year in which a Claim, as defined in Section 11.2(b), is made or
         any refund of a prior Liability attributable to adjustments to the
         income, deductions or credits of any Converge Indemnified Party or the
         Company resulting from any event that is a basis for indemnification
         under this Section 11.

                  (ii) Subsequent to the Closing, subject to the limitations
         contained in Sections 3.5 and 11.3, Converge shall indemnify
         VerticalNet, its Affiliates, and each of their respective partners,
         officers, directors, employees, shareholders and agents, as the case
         may be ("VERTICALNET INDEMNIFIED PARTIES"), against, and hold each of
         the VerticalNet Indemnified Parties harmless from, any Damages
         sustained, suffered or incurred by such VerticalNet Indemnified Party,
         that arise out of or relate to, whether directly or indirectly, the
         breach of any warranty, representation, covenant or agreement of
         Converge contained in this Agreement or delivered by Converge pursuant
         to this Agreement net of any related insurance recoveries and any
         related reductions after Closing in the federal, state or local
         Liability of any VerticalNet Indemnified Party or the Company for Taxes
         paid or payable during the tax year in which a Claim, as defined in
         Section 11.2(b), is made or any refund of a prior Liability
         attributable to adjustments to the income, deductions or credits of any
         VerticalNet Indemnified Party or the Company resulting from any event
         that is a basis for indemnification under this Section 11. In the case
         of Damages actually sustained, suffered or incurred by a VerticalNet
         Indemnified Party ("ACTUAL DAMAGES"), any VerticalNet Indemnified Party
         that is an equity owner of Converge shall be deemed to have sustained,
         suffered or incurred Damages in an amount that is at least equal to
         such VerticalNet Indemnified Party percentage ownership interest in
         Converge multiplied by the amount of such Actual Damages.

                  (iii) To the extent that any Converge Indemnified Party
         recovers a Claim for Damages related to a breach of Section 4.25 due to
         the fact that an account receivable was not collectible within the time
         period set forth therein and payment of such accounts receivable is
         subsequently received, the amount of such payment will promptly be paid
         to Seller.

         The term "DAMAGES" as used in this Section 11.2 is not limited to
matters asserted by third parties against VerticalNet Indemnified Parties or
Converge Indemnified Parties, but includes Damages incurred or sustained by such
Persons in the absence of third party claims. The right to obtain
indemnification provided in this Section 11.2(a) is the sole recourse and remedy
at law or in equity for breaches of this Agreement, other than with respect to
Section 12.2 and 12.3 or as set forth in Section 3.3, in which case, in the
event of any breach or threatened breach by any Party, the non-breaching Party
shall be entitled to injunctive or other equitable relief, restraining such
breaching Party from engaging in conduct that would constitute a breach of the
obligations of a Party under such Sections. Such relief shall be in addition to
and not in lieu of any other remedies that may be available, including an action
for the recovery of Damages.

         (b)      Procedure for Claims.

         If a claim for Damages (a "CLAIM") is to be made by a VerticalNet
Indemnified Party or a Converge Indemnified Party entitled to indemnification
hereunder, the Person claiming such indemnification (the "CLAIMING PARTY") shall
give written notice (a "CLAIM NOTICE") to the indemnifying Person (the
"INDEMNIFYING PARTY") promptly after the Claiming Party becomes aware of any
fact, condition or event which gives rise to Damages for which indemnification
may be sought under this Section 11.2. The failure of any Claiming Party to give
timely notice hereunder shall not affect rights to indemnification hereunder
unless the rights of or remedies available to the Indemnifying Party are
prejudiced by such failure, and then only to the extent thereof. In the event
that fact or circumstance gives rise to a breach of more than one representation
or warranty by an Indemnifying Party, the Claiming Party shall only be entitled
to a make a Claim under one such representation or warranty and shall not have
the right to make a Claim under any other representation or warranty at any
time. In the case of a Claim involving the assertion of a claim by a third party
(whether pursuant to a lawsuit, other legal action or otherwise, a "THIRD-PARTY
CLAIM"), if the Indemnifying Party shall acknowledge in writing to the Claiming
Party that the Indemnifying Party shall be obligated to indemnify the Claiming
Party under the terms of its indemnity hereunder in connection with such
Third-Party Claim, then (i) the Indemnifying Party shall be entitled and, if it
so elects, shall be obligated at its own cost, risk and expense, (A) to take
control of the defense and investigation of such Third-Party Claim and (B) to
pursue the defense thereof in good faith by appropriate actions or proceedings
promptly taken or instituted and diligently pursued, including employing and
engaging attorneys of its own choice reasonably acceptable to the Claiming Party
to handle and defend the same, and (ii) the Indemnifying Party shall be entitled
(but not obligated), if it so elects, to compromise or settle such claim, which
compromise or settlement shall be made only with the written consent of the
Claiming Party, such consent not to be unreasonably withheld. In the event the
Indemnifying Party elects to assume control of the defense and investigation of
such lawsuit or other legal action in accordance with this Section 11.2(b), the
Claiming Party may, at its own cost and expense, participate in the
investigation, trial and defense of such Third-Party Claim; provided that, if
the named Persons to a lawsuit or other legal action include both the
Indemnifying Party and the Claiming Party and the Claiming Party has been
advised in writing by counsel that there may be one or more legal defenses
available to such Claiming Party that are different from or additional to those
available to the Indemnifying Party, the Claiming Party shall be entitled, at
the Indemnifying Party's cost, risk and expense, to retain one firm of separate
counsel of its own choosing. If the Indemnifying Party fails to assume the
defense of such Third-Party Claim in accordance with this Section 11.2(b) within
10 Business Days after receipt of the Claim Notice, the Claiming Party against
which such Third-Party Claim has been asserted shall (upon delivering notice to
such effect to the Indemnifying Party) have the right to undertake, at the
Indemnifying Party's cost, risk and expense, the defense, compromise and
settlement of such Third-Party Claim on behalf of and for the account of the
Indemnifying Party; provided that such Third-Party Claim shall not be
compromised or settled without the written consent of the Indemnifying Party,
which consent shall not be unreasonably withheld. In the event the Indemnifying
Party assumes the defense of the claim, the Indemnifying Party shall keep the
Claiming Party reasonably informed of the progress of any such defense,
compromise or settlement, and in the event the Claiming Party assumes the
defense of the claim, the Claiming Party shall keep the Indemnifying Party
reasonably informed of the progress of any such defense, compromise or
settlement. The Indemnifying Party shall be liable for any settlement of


                                      -56-
<PAGE>   58
any Third-Party Claim effected pursuant to and in accordance with this Section
11.2 and for any final judgment (subject to any right of appeal), and the
Indemnifying Party shall indemnify and hold harmless each Claiming Party from
and against any and all Damages by reason of such settlement or judgment.

         11.3     Threshold; Limitations on Indemnity.

         (a) The Converge Indemnified Parties shall not be entitled to recover
for any Damages until such time as the Damages claimed by the Converge
Indemnified Parties in the aggregate exceed $1.5 million (the "DAMAGE
THRESHOLD"), at which time the Converge Indemnified Parties shall be entitled to
be indemnified against and compensated and reimbursed for all such Damages in
excess of the initial $500,000 thereof. Notwithstanding the foregoing, the
maximum amount of Damages claimed by the Converge Indemnified Parties, in the
aggregate, shall not exceed the lesser of Cash Consideration or $52 million.

         (b) The VerticalNet Indemnified Parties shall not be entitled to
recover for any Damages until such time as the Damages claimed by the
VerticalNet Indemnified Parties in the aggregate exceed the Damage Threshold, at
which time the VerticalNet Indemnified Parties shall be entitled to be
indemnified against and compensated and reimbursed for all such Damages in
excess of the initial $500,000 thereof. Notwithstanding the foregoing, the
maximum amount of Damages claimed by the VerticalNet Indemnified Parties, in the
aggregate, shall not exceed the lesser of the Cash Consideration or $52 million.

         (c) Any claim for a breach of a covenant or of the representations and
warranties of the Parties contained in this Agreement shall survive the Closing
until September 30, 2002, except the representations and warranties set forth in
Sections 4.9, 4.16, 4.22, 4.23, 6.9 and 6.21 and the covenants contained in
Section 7.6 shall survive the Closing Date until the earlier of the fifth
anniversary of the Closing Date or the date that is 20 Business Days after the
date of the expiration of the applicable statute of limitations (including any
extensions thereof). The covenants and agreements (including any covenants and
agreements contained within the representations and warranties in Article 4, 5
or 6) of the Parties hereto shall survive the Closing until performed in
accordance with their terms. In the event that more than one such survival
period should apply to a Claim the shorter survival period shall be deemed to
govern the ability of a Claiming Party to timely bring such Claim.

                                  ARTICLE 12.

                                  MISCELLANEOUS

                  (ii) By Converge or VerticalNet if the Closing shall not have

<PAGE>   59
                  (iii) By Converge if there is a material breach of any
         representation or warranty set forth in Article 4 or Article 5 or any
         covenant or agreement to be complied with or performed by the Company
         or VerticalNet pursuant to the terms of this Agreement and such breach
         persists for 10 Business Days or more after notice is given, so long as
         any such breach is not caused solely by the action or inaction of
         Converge;

                  (iv) By VerticalNet if there is a material breach of any
         representation or warranty set forth in Article 6 hereof or of any
         covenant or agreement to be complied with or performed by Converge
         pursuant to the terms of this Agreement and such breach persists for 10
         Business Days or more after written notice is given, so long as any
         such breach is not caused solely by the action or inaction of the
         Company or VerticalNet; or

                  (v) By Converge or VerticalNet if a court of competent
         jurisdiction or governmental authority shall have issued a final and
         nonappealable order in writing, or shall have taken such other action
         having the effect of permanently restraining, enjoining, or otherwise
         prohibiting the consummation of the transactions contemplated hereby.

         (b) In the event of termination of this Agreement:

                  (i) The provisions of the Confidentiality Agreement and
         Sections 4.22(j), 12.1(b), 12.2, 12.5, 12.7, 12.9 through 12.11, and
         12.13 shall continue in full force and effect; and

                  (ii) Except as otherwise specified herein, no Party shall have
         any liability to any other Party, except for any willful breach of, or
         knowing misrepresentation made in, this Agreement occurring prior to
         the formal termination of this Agreement.

         (c) So long as Converge shall not have breached its obligations

"KEY EMPLOYEE") or (ii) prior to December 8, 2001, solicit any employee of the
other Party to cease their current employment and become an employee of the
soliciting party (except as is implicit in an acquisition of the Company by
Converge). Except with respect to Key Employees, this provision does not
prohibit a party's responding to unsolicited employment inquiries and/or
indirect solicitations and other employment activities (e.g., job postings,
advertising of positions) that are not specifically targeted at any particular
individual.

         12.3 Assignment. Neither this Agreement nor any of the rights or
obligations hereunder may be assigned by the Company or VerticalNet without the
prior written consent of Converge, or, subject to the following sentence, by

acquire, from the Company or any of its Subsidiaries any Proprietary Rights or
other Assets owned by the Company or such Subsidiary, for such amount payable in
Stock Consideration or Cash Consideration, in each case as the parties may
agree; provided that the amount of Stock Consideration or Cash Consideration

been paid to acquire any Asset pursuant to this Section 12.3.

         12.4 Notices. Unless otherwise provided herein, any notice, request,
