8.   DISPUTE RESOLUTION

    8.1.  Negotiation and Escalation.  If any controversy or claim arises
relating to this Agreement, the Parties will attempt in good faith to negotiate
a solution to their differences, including progressively escalating any
controversy or claim through senior levels of management.  If negotiation does
not result in a resolution within 30 days of the date one Party first notifies
the other of the controversy or claim, either Party may resort to arbitration
under Section 8.2.

    8.2.  Arbitration.  Any controversy or claim between the Parties concerning
any breach or alleged breach of this Agreement or performance or nonperformance
of any obligation under this Agreement or otherwise with respect to this
Agreement which cannot be resolved by negotiation will be resolved by binding
arbitration under this Section 8.2 and the then-current Commercial Rules and
supervision of the American Arbitration Association (the "AAA"). If any part of
this Section 8.2 is held to be unenforceable, it will be severed and will not
affect either the duty to arbitrate or any other part of this Section 8.2.  The
arbitration will be held in Philadelphia, Pennsylvania, before a sole
disinterested arbitrator who is knowledgeable in business information and the
Internet and experienced in handling commercial disputes.  The arbitrator shall
be appointed jointly by the Parties hereto within 30 days following the date on
which the arbitration is instituted.  If the Parties are unable to agree upon
the arbitrator within such 30-day period, the AAA shall be instructed to select
such arbitrator within 15 days thereafter.  The arbitrator's award will be final
and binding and may be entered in any court having jurisdiction.  The arbitrator
will not have the power to award punitive or exemplary damages, or any damages
excluded by, or in excess of, any damage limitations expressed in this
Agreement.  Issues of arbitrability will be determined in accordance solely with
the federal substantive and procedural laws relating to arbitration; in all
other respects, the arbitrator will be obligated to apply and follow the
substantive law of the Commonwealth of Pennsylvania.

    8.3.  Equitable Relief.  Notwithstanding anything to the contrary in this
Agreement, in the event of an alleged violation of Article 9 of this Agreement
by either Party, the Party alleging such a violation may seek temporary and
permanent injunctive or other appropriate equitable relief from any court of
competent jurisdiction pending appointment of an arbitrator.  The Party
requesting such relief shall simultaneously file a demand for arbitration of the
dispute, and shall request that the AAA proceed under its rules for an expedited
hearing.

    8.4.  Costs. Unless the arbitrator, if any, determines otherwise, each Party
will bear its own attorneys' fees and other costs associated with the
negotiation and arbitration provided for by this Article 8, except that costs
and expenses of the arbitrator shall be shared equally. If court proceedings to
stay litigation or compel arbitration are necessary, the Party who
unsuccessfully initiates or opposes such proceedings will pay all associated
costs, expenses and attorneys' fees that are reasonably incurred by the other
Party.  To the extent that any claim in arbitration relates to the collection of
amounts owed under Article 6, the Party entitled to collect such amounts shall
be entitled to recover all reasonable costs of collection, including expenses
and attorneys' fees that are reasonably incurred.

    8.5.  Two Year Limitation.  Except for claims under Sections 11.4 and 11.5
hereof, neither Party may bring a claim or action regardless of form, arising
out of or related to

                                       9
<PAGE>

this Agreement, including any claim of fraud or misrepresentation, more than two
years after the cause of action accrues or becomes known, whichever is later.

    8.6.  Confidentiality.  In order to facilitate the resolution of
controversies or claims between the Parties with respect to each Party hereto,
such controversies or claims, including details regarding negotiations,
arbitration and settlement terms, shall be treated as Confidential Information
of the other Party hereto in accordance with Article 9.

    8.7.  Remedial Measures. In the event of (a) any material remediable breach
of this Agreement by the other Party which remains uncured 30 days after notice
of such breach (other than a breach of a payment obligation) was received by the
other Party or (b) any material breach which cannot be cured, the non-breaching
Party may take reasonable remediable measures upon prior written notice and at
the cost and expense of the breaching Party without prejudice and in addition to
any other rights arising from such breach.  In addition, the non-breaching Party
shall take reasonable steps to mitigate damages arising out of such breach.

9.   CONFIDENTIALITY

    9.1.  Confidentiality Obligations.  Except as permitted elsewhere under this
Agreement, each Party agrees to take Reasonable Steps (as defined below) (a) to
receive and maintain the Confidential Information of the other Party in
confidence and (b) not to disclose such Confidential Information to any third
parties, provided, the receiving Party may disclose such Confidential
Information to its employees, representatives and agents who have a need to know
such information for purposes of carrying out the terms of this Agreement.
Neither Party hereto shall use all or any part of the Confidential Information
of the other Party for any purpose other than to perform its obligations under
this Agreement.  The Parties will take Reasonable Steps (as defined below) to
ensure that their employees, representatives and agents comply with this
provision.  As used herein, "Reasonable Steps" means at least the same degree of
care that the receiving Party uses to protect its own Confidential Information,

Party; (b) was already known to the receiving Party at the time it was disclosed

of or access to such information, as evidenced by records of the receiving
Party; (d) is received from a third party who is under no obligation of
confidentiality to the disclosing Party; or (e) must be disclosed pursuant to
applicable laws, rules or regulations; provided, however, that the receiving

    9.4.  Injunction.  Each Party acknowledges and agrees that the provisions of
this Article 9 are reasonable and necessary to protect the other Party's
interests in its Confidential Information, that any breach of the provisions of
this Article 9 may result in irreparable harm to such other Party, and that the
remedy at law for such breach may be inadequate.  Accordingly, in the event of
any breach or threatened breach of the provisions of this Article 9 by a Party
hereto, the other Party, in addition to any other relief available to it at law,
in equity or otherwise, shall be entitled to seek temporary and permanent
injunctive relief restraining the breaching Party from engaging in and/or
continuing any conduct that would constitute a breach of this Article 9, without
posting a bond or other security.

    9.5.  Publicity. Except as may be required by law in which case a party will
provide as much advance notice as reasonably possible, neither Party will
originate any press release concerning the relationship between the Parties or
the transactions described in this Agreement without the prior written consent
of the other Party, which consent shall not be unreasonably withheld or delayed.
Notwithstanding the foregoing, as soon as reasonably practicable following the
Effective Date, VerticalNet and LeadersOnline shall jointly issue a press
release with respect to entering into this Agreement.

    9.6.  User Data. LeadersOnline shall provide VerticalNet with User Data on
each User that enters the LeadersOnline Site through a Link from a VerticalNet
Site and submits information through the LeadersOnline Site by sending an email
with such information to an email address designated by VerticalNet at the time
the request occurs.  User Data shall be maintained by each Party as Confidential
Information of the other Party during the Term and 5 years thereafter, provided
such User Data may be disclosed only as part of an aggregation or analysis of
all User Data but not as independent data.  Upon termination of the Agreement,
VerticalNet and LeadersOnline shall jointly own all User Data. Neither Party
shall use the User Data other than in accordance with the VerticalNet privacy
policy and all applicable laws during the Term and thereafter.

to which indemnity may be sought from the other Party pursuant to the provisions
of this Article 11, the Party seeking indemnity (the "Indemnitee") shall follow
the procedures in this Section.  If an Indemnitee receives any notice of a claim
or other allegation with respect to which the other Party (the "Indemnitor") has
an obligation of indemnity hereunder, then the Indemnitee will, as soon as
reasonably possible after receipt of such notice, give the Indemnitor written
notice of such claim or allegation setting forth in reasonable detail the facts
and circumstances surrounding the claim.  The Indemnitee will not make any
payment or incur any costs or expenses with respect to such claim, except as
requested by the Indemnitor or as necessary to comply with this procedure.  The
Indemnitee will not make any admission of liability or take any other action
that limits the ability of the Indemnitor to defend the case.  The Indemnitor
shall immediately assume the full control of the defense or settlement of such
claim or allegation, including the selection and employment of counsel, and

settlement of the claim.  The Indemnitee shall have the right, at its own
expense, to employ separate counsel and participate in the defense or settlement
of the claim; provided that the Indemnitor shall have no liability for costs or
expenses incurred by the Indemnitee, except to the extent authorized by the
Indemnitor pursuant to this procedure.  The

                                       13
<PAGE>

Indemnitor will not agree to any settlement that does not include a complete
release of the Indemnitee.
