PENTAIR LTD. 2012 STOCK AND INCENTIVE PLAN GRANT AGREEMENT RESTRICTED STOCK UNITS

1/2 of the units on the third anniversary of the Closing Date (as defined in the Merger Agreement)

1/2 of the units on the fourth anniversary of the Closing Date

The Restricted Stock Units become “vested” on the vesting dates noted above. The Shares underlying the Restricted Stock Units will be issued upon vesting. In the event the vesting date falls on a weekend day or holiday, the Restricted Stock Units will vest and Shares will be issued on the next trading day.

Each Restricted Stock Unit includes one Dividend Equivalent Unit. A Dividend Equivalent Unit entitles you to a cash payment equal to the cash dividends declared on a Share of stock during the vesting period. Payment of the Dividend Equivalent Units will be made to you in cash as soon as practicable after the dividend payment date. Dividend Equivalent Units are not eligible for dividend reinvestment.

If your employment with the Company terminates (a) by you for Good Reason (as defined in and subject to the provisions of your Key Executive Employment and Severance Agreement with the Company as in effect on the date hereof (your “KEESA”)), (b) in an involuntary termination by the Company without Cause (as defined in and subject to the provisions of your KEESA) or (c) due to your death or disability (as defined in and pursuant to the terms of your KEESA) before your Restricted Stock Units are 100% vested, then a pro rata portion of your Restricted Stock Units will become vested upon such termination based on the portion of the full four-year vesting period that has elapsed at the time of such termination. If your employment with the Company terminates as a result of your Retirement, death or Disability, then the Plan’s provisions will apply (to the extent that they provide a better result). Except as provided herein, any Restricted Stock Units remaining unvested immediately following your termination of employment will be forfeited.

If the Restricted Stock Units vest upon termination of employment, then the Shares underlying the Restricted Stock Units that vest will be issued promptly after your termination. If, however, you are a “specified employee” within the meaning of Code Section 409A of the Code at the time of your termination, then the issuance of the Shares for those Restricted Stock Units that vest as a result of your termination will be delayed for six months following your termination to the extent needed to comply with Code Section 409A.

The Restricted Stock Units will also vest upon a Change of Control provided you are still employed with the Company immediately prior to the Change of Control. The term “Change of Control” as applied to your Restricted Stock Units is modified to comply with Code Section 409A.

You cannot vote Restricted Stock Units.

You may not sell, assign, transfer, pledge as collateral or otherwise dispose of your Restricted Stock Units at any time during the vesting period.

The Fair Market Value of the Shares that are issued upon vesting of the Restricted Stock Units and the cash paid in respect of Dividend Equivalent Units generally will be considered taxable compensation, and may be subject to withholding taxes.

If you become Retirement eligible while this award is in effect, the value of your Restricted Stock Units that would be vested if you actually retired will be subject to Federal Insurance Contributions Act (“FICA”) taxes even if the award is not yet paid. Normally, such FICA taxes will be withheld at the end of the calendar year. A similar rule applies upon termination due to Good Reason, Cause or disability if the issuance of the Shares is subject to the 6-month delay under Code Section 409A.

Please refer to the Frequently Asked Questions (FAQs) for Restricted Stock Units for information about the methods of payment of your tax withholding obligations.

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.

The vesting of this award may be suspended or delayed as a result of a leave of absence.

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 Restricted Stock 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.
