(i)    To DPC's knowledge, as of the Effective Date, any activity performed by or on behalf of DPC under this Agreement (including, without limitation, the practice of any of DPC's manufacturing processes or technology, but excluding use of API in accordance with this Agreement) would not infringe any patent, trademark, trade secret or other proprietary right of any third party.

ARTICLE 15: GOVERNING LAW AND DISPUTE RESOLUTION

15.1    Good Faith Negotiation.    Any controversy, claim or dispute arising out of or relating to this Agreement or the breach of this Agreement shall be settled, if possible, through good faith negotiation between the parties.

before three (3) arbitrators. Such arbitration shall take place in New York, New York and shall proceed in accordance with the Commercial Arbitration Rules of the American Arbitration Association ("AAA"). Within seven (7) calendar days of either party making a demand for arbitration (or longer if the parties so agree), NovaCardia and DPC shall each select one (1) arbitrator. A third (3^rd) arbitrator shall be selected by the arbitrators selected by the parties within thirty (30) days of the demand for arbitration. In the event that either party shall fail to appoint its arbitrator, or the two (2) arbitrators selected by the parties fail to appoint a third (3^rd) arbitrator, in either case within the prescribed time period, then either party may apply to the AAA for the appointment of such arbitrator. The determination of a majority of the panel of arbitrators shall be the decision of the panel and shall be binding regardless of whether one of the parties fails or refuses to participate in the arbitration. The panel shall be authorized to award compensatory damages, but shall NOT be authorized (i) to award non-economic damages, such as for emotional distress, pain and suffering or loss of consortium, (ii) to award punitive damages, or (iii) to reform, modify or materially change this Agreement or any other agreements contemplated hereunder; provided, however, that the damage limitations described in subsections (i) and (ii) of this sentence will not apply if such damages are statutorily imposed. The panel also shall be authorized to grant any temporary, preliminary or permanent equitable remedy or relief it deems just and equitable and within the scope of this Agreement, including, without limitation, an injunction or order for specific performance. The determination of the panel shall be enforceable by any court of competent jurisdiction. Nothing herein shall limit or restrict a party's ability to seek injunctive or other equitable relief in the event of a breach or anticipated breach of Article 7.

15.3    Payment of Costs.    Each party shall pay for the arbitrator it selects with the cost of the third (3^rd) arbitrator being split equally between the parties. All other costs shall also be split equally between the parties. Either party may enter any arbitration award in any court having jurisdiction or may make application to any such court for a judicial acceptance of the award and order of enforcement, as the case may be. The parties' agreement to submit to arbitration referred to herein shall in no way prevent either party from exercising its right to terminate this Agreement consistent with the terms herein.

15.4    Equitable Remedies From A Court of Law.    Each party has the right before or during the arbitration to seek and obtain from the appropriate court provisional remedies, such as attachment, preliminary injunction or replevin, to avoid irreparable harm, maintain the status quo, or preserve the subject matter of the arbitration.

15.5    Intellectual Property and Anti-Trust.    This Article 15 shall not apply to any dispute, controversy or claim that concerns (i) the validity or infringement of a patent, trademark or copyright; or (ii) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory.

15.6    Waiver and Acknowledgement.    By agreeing to this binding arbitration provision, the parties understand that they are waiving certain rights and protections which may otherwise be available to such party in court, including, without limitation, the right to seek or obtain certain types of damages precluded by this provision, the right to a jury trial, certain rights of appeal, and a right to invoke formal rules of procedure and evidence.

ARTICLE 16: FORCE MAJEURE

ARTICLE 17: NOTICES
