                                       11
<PAGE>

     Asymetrix or a breach by Asymetrix of a representation and/or warranty made

     liability, cost, loss, or expense of any kind; and (ii) hold harmless

     b. BY GO2NET. With respect to claims or actions against one or both parties
     by third parties insofar as such claim, demand or action is attributable to
     the acts or omissions of Go2Net or a breach by Go2Net of a representation
     and/or warranty made in this Agreement, Go2Net shall (i) indemnify
     Asymetrix against any liability, cost, loss, or expense of any kind; and

     c. PROCEDURE. If any action shall be brought against a party in respect to
     which indemnity may be sought from the other party pursuant to the
     provisions of this Section, 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, within fifteen (15) days of 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 required
     to comply with this procedure. 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 shall pay all
     authorized costs and expenses of such defense and settlement. The
     indemnified party must consent to any settlement that imposes restrictions
     on or requires the Indemnitee to contribute financially to such settlement.
     The Indemnitee will fully cooperate, at the expense of the Indemnitor, in
     the defense or 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.

34.  DISPUTE RESOLUTION. If any dispute arises under this Agreement, the parties
shall make a good faith effort to resolve the dispute before taking any action.
The parties shall meet to discuss the dispute no later than thirty (30) days
after either party gives written notice to the other party that such a dispute
exists. Such meeting may be held telephonically if travel is impractical for
either party. At such meeting, an officer of each of Asymetrix and who has
authority to resolve the dispute shall be in attendance. No action, suit,
arbitration or other proceeding may be commenced before the parties have met
pursuant to this provision unless immediate injunctive relief is being sought,
in which case the noted meeting shall take place at the earliest opportunity
after such immediate injunctive relief is sought.

35.  WAIVER OF JURY TRIAL. The parties hereby agree to waive their respective
rights to a jury trial of any claim or cause of action related to or arising out
of this Agreement. The scope of the waiver is intended to be all encompassing of

the waiver. The waiver is irrevocable, meaning that it may not be modified

                                       12

breach of this Agreement or any of the warranties herein, the prevailing party
shall be entitled to recover its reasonable attorneys' fees and other costs
incurred in bringing such action or proceeding, in addition to any other relief
to which such party may be entitled.

obligation, effective immediately upon giving notice.

fifteen (15) days of notice of such breach.

42.  WAIVER OF BREACH. A breach of any provision of this Agreement may only be
waived in writing and the waiver of such breach shall not operate or be
construed as a waiver of any subsequent breach.

43.  SEVERABILITY. If any provision of this Agreement should, for any reason, be
held invalid or unenforceable in any respect, the remainder of this Agreement
shall be enforced to the full extent permitted by law. A court of competent
jurisdiction is hereby empowered to modify the invalid or unenforceable
provision to make it valid and enforceable.

44.  PERFORMANCE EXCUSED. The parties shall be excused from delays in performing
or from any failure to perform hereunder to the extent that such delay or
failure result from causes such as war or natural disaster or strike which are
beyond the reasonable control of the party, provided that, in order to be
excused from delay or failure to perform, the party must act diligently to
remedy such delay or failure. In the event such delay continues for ten (10)
consecutive days, either party shall have the right to terminate this Agreement.
