     11.9 Governing Law/Arbitration. This Agreement shall be construed and
enforced in accordance with the laws of the State of Florida. Any dispute
between the parties arising out of or relating to this Agreement or its breach
that cannot be resolved within sixty (60) days of written notice of the
existence of a dispute will be resolved in binding arbitration administered by
the American Arbitration Association under its Commercial Arbitration Rules and
Procedures for Large Complex Commercial Disputes. Unless otherwise agreed to in
writing by the parties, a single neutral arbitrator agreeable to both parties
will conduct such arbitration, and the arbitrator shall have the authority to
award reasonable attorneys' fees and expenses in his or her discretion. Unless
otherwise agreed by the parties, such arbitration shall be held in the State of
Florida if initiated by ATS MEDICAL and shall be held in the State of Minnesota
if initiated by ATC. Judgment upon any arbitration award may be entered in any
court of competent jurisdiction. Nothing herein shall preclude a party from
seeking an injunction or order requiring performance from any court of competent
jurisdiction. Should any part or provision of this Agreement be held
unenforceable or in conflict with the law of any jurisdiction, the validity of
the remaining parts or provisions shall not be affected by such holding. In the
event a part or provision of this Agreement is held unenforceable or in conflict
with the law affecting consideration to either

event beyond such Party's reasonable control and without the fault or negligence
of the Party seeking to excuse performance, including, but not limited to, acts
of God, fire, terrorism, explosion, weather, plague, war, insurrection, civil
strife or riots, provided, however, such performance shall be excused only to
the extent of and during such disability and such Party makes commercially
reasonable efforts to remove the disability. Any Party seeking to excuse or

the other Party of the nature and anticipated duration of the delay.
