If negotiation does not result in a resolution within 30 days of when one Party first notifies the other of the controversy or claim, either Party may resort to arbitration under Section 12.2 [ARBITRATION]. 12.2 ARBITRATION.

If any part of this Section 12.2 [ARBITRATION] 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 12.2 [ARBITRATION]. 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. 12.3 EQUITABLE RELIEF. Notwithstanding anything to the contrary in this Agreement, in the event of an alleged violation of Article 13 [CONFIDENTIALITY] of this Agreement by either Party, the Party alleging such a violation may seek temporary injunctive or other appropriate equitable relief from any court of competent jurisdiction pending appointment of an arbitrator.

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 12 [DISPUTE RESOLUTION], except that costs and expenses of the arbitrators shall be shared equally. If court proceedings to stay litigation or compel arbitration are necessary, the Party who unsuccessfully opposes such proceedings will pay all associated costs, expenses and attorneys' fees that are reasonably incurred by the other Party. 12.5 TWO YEAR LIMITATION. Except for claims under Sections 15.4 [INDEMNIFICATION BY NEOFORMA] and 15.5 [INDEMNIFICATION BY VERTICALNET] hereof, neither Party may bring a claim or action regardless of form, arising out of or related to this Agreement, including any claim of fraud or misrepresentation, more than two years after the cause of action accrues or Source: NEOFORMA INC, S-1/A, 12/2/1999 becomes known, whichever is later. 12.6 CONFIDENTIALITY.
