• You may defer your Performance Units under the employer’s non-qualified deferred compensation plan. If you make a deferral election, then the Performance Units subject to that election will not be paid following the end of the performance period, but will instead be paid pursuant to the terms of the non-qualified deferred compensation plan.

• If your employment with the Company terminates (voluntarily or involuntarily) before the end of the performance period, all Performance Units will be forfeited. Exceptions to this rule are made for certain types of terminations, including termination due to death, Disability or Retirement, in accordance with the terms of the Plan.

• The cash paid for the earned Performance Units is considered taxable wages. To the extent required by law, the Company will withhold all applicable withholding taxes from the payment.

General

• The grant of this Plan award to you does not limit in any way the right of the Company to terminate your employment at any time for any reason, nor does it guarantee you will receive Plan awards in subsequent years.

• If the Compensation Committee of the Pentair Ltd. Board of Directors (the “Committee”) determines that recoupment of incentive compensation paid to you pursuant to this grant agreement is required under any law or any recoupment policy of the Company, then your Performance Units will terminate immediately on the date of such determination to the extent required by such law or recoupment policy and the Committee may recoup any such incentive compensation in accordance with such recoupment policy or as required by law. The Company shall have the right to offset against any other amounts due from the Company to you the amount owed by you hereunder.

• The Committee may amend or modify the Plan at any time but generally such changes will apply to future Plan awards. The Committee may also amend or modify this award, but most changes will require your consent.
