business on the business days occurring in the Quarter. If there exist currency translation restrictions, embargoes, or other currency restrictions that would prevent THRESHOLD, its Affiliates, or Sub-Licensees from converting local currency into United States dollars and remitting the same to ▇▇▇▇▇▇ ONCOLOGY, THRESHOLD, its Affiliates and Sub-Licensees shall be entitled to pay ▇▇▇▇▇▇ ONCOLOGY in the local currency in the country where such restrictions exist.

Said findings shall be maintained in confidence by BAXTER ONCOLOGY. Findings on the accuracy or supposed inaccuracy of such payment shall be disclosed to ▇▇▇▇▇▇ ONCOLOGY by such representative who shall, at the time of reporting his conclusions to ▇▇▇▇▇▇ ONCOLOGY, supply THRESHOLD with a copy of such findings.

15.1

The construction, validity and performance of this Agreement shall be governed in all respects by the laws of the State of California without taking into consideration any of its conflict of laws provisions.

15.2

The Parties will attempt in good faith to resolve any dispute, controversy or claim arising out of or relating to the interpretation, performance or enforceability of this Agreement promptly by negotiation between executives of the Parties. In the event that such negotiations do not result in a mutually acceptable resolution, the Parties agree to consider other dispute resolution mechanisms including mediation and arbitration. In the event that the Parties fail to agree on a mutually acceptable solution within a period of thirty (30) business days, any such dispute shall be submitted to binding arbitration.

15.3

Such arbitration shall be conducted in accordance with the American Arbitration Association. Notwithstanding those rules, the following

provisions shall in any event apply to any issue submitted for arbitration hereunder:

15.3.1

The arbitration shall be conducted by a panel of three (3) neutral arbitrators (“Panel”). One (1) arbitrator shall be appointed by each Party and the third member shall be appointed by the two (2) arbitrators appointed by the Parties. Each Party will select an arbitrator within fifteen (15) business days following the demand for arbitration. The two (2) arbitrators selected by the Parties will appoint the third arbitrator within ten (10) days following their appointment. Notwithstanding the above and in the interest of obtaining a judgment within the shortest possible period in connection with certain bona fide disputes or technical or developmental matters that require referral to independent experts, the Parties may agree to appoint only one (1) single neutral arbitrator selected in agreement by both Parties.

15.3.2

The language to be used in the arbitration shall be English.

15.3.3

Any arbitrator selected by the Parties may be of any nationality, and need not be a lawyer or hold any other professional status or membership but will be selected on the basis of his or her qualifications and expertise with respect to the matter under dispute.

15.3.4

The arbitration shall be held in New York, New York.

15.3.5

The specific pleading schedule for each proceeding shall be determined by the Parties in consultation with the Panel within fifteen (15) business days following the selection of the arbitrators.

15.3.6

Unless the Parties otherwise agree at the time a particular issue is submitted for arbitration, the Panel shall be required as a condition to their engagement to agree to render a decision within thirty (30) days of the date on which the record in the proceeding is completed, but in no case more than one hundred and twenty (120) days after the date of their engagement. The time period for cure specified in Clause 11 shall be suspended upon institution of arbitration until completion of such arbitration.

15.3.7

The Parties shall use their best efforts to schedule and make their submissions, and to take all other necessary actions in connection with the proceeding, at a time and in a manner which will permit the Panel to render their decision in accordance with the schedule set forth herein.

15.3.8

All communications with the arbitrator(s) during the proceeding shall be made in writing, with a copy thereof delivered simultaneously to the other Party to the proceeding, or if made

orally, made only in the presence of the other Party to the proceeding or its representative.

15.3.9

All decisions by the Panel shall be rendered by majority vote. The arbitration award or order shall be rendered in writing and shall be final and binding upon the Parties. The arbitrator(s) shall establish and enforce appropriate rules to ensure that the arbitration proceedings, including the decisions, are kept confidential and that all confidential and/or proprietary information of the Parties is kept confidential and is used for no purpose other than for such arbitration proceedings.

15.3.10

Judgment on any order or award shall be entered by any court of competent jurisdiction.

15.3.11

Each Party shall bear its own expenses and attorney’s fees in connection with the arbitration.

15.3.12

The fees and expenses of the arbitrator(s) shall be equally shared except that if, in the opinion of the arbitrators, any claim by a Party hereto or any defense or objection thereto by the other Party was unreasonable and frivolous, the arbitrators may in their discretion assess as part of the award all or any part of the arbitration expenses of the other Party (including reasonable attorney’s fees) and expenses of the arbitrators against the Party raising such unreasonable and frivolous claim, defense or objection.
