(f)interpret the provisions of the Plan, including, but not limited to, determining vesting percentages of Performance Units.

4.Eligibility and Participation. Key employees of the Company and/or its subsidiaries are designated for participation in the Plan by the Committee. The Committee shall also designate the number of Performance Units to be granted to the Employee at the Target 100% rate.

(a)Performance Unit Defined. A Performance Unit is a right to receive a cash payment from the Company that is based upon the value of shares of Company Stock and is contingent on the Company's achievement with respect to applicable Performance Measure(s) during a three-year performance period. The Committee may establish the three-year performance periods. The Performance Units granted under this Plan will be reflected in a book account maintained by the Company for each Employee until they have become vested or have been forfeited.

(b)Short-Term Dividend Equivalents The Company will increase the number of Unvested Performance Units as of any date that the Company declares a cash dividend on its shares of Common Stock by the amount of the "Short-Term Dividend Equivalents." Short-Term Dividend Equivalents shall be calculated by:

Short-Term Dividend Equivalents shall be treated as additional Unvested Performance Units and shall be subject to the same vesting, forfeiture, payment, termination and other terms, conditions and restrictions as the original Performance Units to which they relate. Short-Term Dividend Equivalents shall also be treated as Unvested Performance Units for purposes of calculating future Short-Term Dividend Equivalents. Short-Term Dividend Equivalents shall not be granted with respect to any Performance Units which, as of the declaration date, have either been paid or terminated.

(c)Vesting Of Performance Units. The Performance Units are subject to forfeiture until they vest. The vesting percentage of an Employee's Unvested Performance Units shall be calculated as outlined below.

[a]    The Committee, in its sole discretion, will select one or more Performance Measure(s) to apply to a grant of Performance Units. The Committee will select the applicable Performance Measure(s) at the beginning of the three-year performance period. The Committee may determine achievement within a Performance Measure over the entire three-year performance period or on an annual basis. A Performance Measure may be based on any combination of Company, subsidiary or divisional standards. Performance Measures may have the same or different weightings in relation to Performance Unit vesting.

The calculation of the Employee's vesting percentage, if the Performance Measure requires comparison relative to a peer group, shall be subject to the following rules:

[i]    The Committee shall select the benchmark utilities at the beginning of the three-year performance period.

(d)Special Vesting Of Performance Units. Unvested Performance Units shall become immediately vested upon the occurrence of any of the following events (the "Special Vesting Events"):

(e)Prorated Vesting upon Retirement. A prorated number of the Unvested Performance Units shall become vested upon the termination of the Employee's employment with the Company or a subsidiary by reason of Retirement prior to the end of the three-year performance period. The number of Unvested Performance Units becoming vested shall be determined by multiplying the number of Unvested Performance Units by a fraction, with the numerator of the fraction being the number of completed calendar months between Employee's Retirement date and the beginning of the performance period and the denominator being thirty-six (36).

Therefore, if Employee retires on September 15 of the second year in the three-year performance period, the number of Unvested Performance Units becoming vested as a result of Employee's Retirement shall be equal to the number of Unvested Performance Units times 20/36.

(f)Forfeiture of Performance Units. Except as provided in paragraphs (d) and (e) above, any Unvested Performance Units are immediately forfeited upon the Employee's cessation of employment with the Company or a subsidiary prior to the completion of the three-year performance period.

6.Shareholder Rights; Voting. An Employee shall not, by reason of any Performance Units granted hereunder, have any rights of a shareholder of the Company and shall have no voting rights with respect to any Performance Units.

8.Beneficiary Designation. Each Participant under the Plan may, from time to time, name any beneficiary or beneficiaries (who may be named contingently or successively) to whom any benefit under the Plan is to be paid in case the Participant dies before receiving any or all of such benefit. Each designation will revoke all prior designations by the same Participant, shall be in a form prescribed by the Company and will be effective only when submitted to the Company during the Participant's lifetime. To the extent authorized by the Committee, the designation may be made electronically or set forth in some other media or format. In the absence of any such designation, or if the beneficiary predeceases the Participant, benefits remaining unpaid at the Participant's death shall be paid to the Participant's surviving spouse, if none, to the Participant's descendants by right of representation or, if none, to the Participant's next of kin determined pursuant to the laws of the state in which the Company's principal place of business is located as if the Participant had died unmarried and intestate. In the event of a Participant's divorce, any designation of the Participant's former spouse as a beneficiary shall be void unless after the divorce the Participant completes a new designation naming such former spouse as a beneficiary.

9.Adjustments. Notwithstanding any other provision herein, in the event of any merger, reorganization, consolidation, recapitalization, liquidation, stock dividend, split-up, share combination, or other change in the corporate structure of the Company affecting the Company Stock, such adjustment shall be made in the number of Performance Units granted to Employees as may be determined by the

10.Tax Withholding. The Company shall have the right to deduct from any payment made under the Plan the amount of any federal, state or local taxes of any kind required by law to be withheld with respect to the grant, vesting, payment or settlement of an award under this Plan, or to take such other action as may be necessary in the opinion of the Company to satisfy all obligations for the payment of such taxes.

11.Governing Law. The law of the State of Wisconsin, except its law with respect to choice of law, shall be controlling in all matters relating to the Plan.

12.Plan Amendment and Termination.

13.Acceptance of Performance Units. A participant must accept Performance Units granted under this Plan, including all terms and conditions of the Plan, in a time and manner as specified by the Company. To the extent authorized by the Committee, the acceptance may be made electronically or set forth in some other media or format.

14.Miscellaneous. If the Committee determines in its discretion that a benefit under this Plan is to be paid to a minor, a person declared incompetent or to a person incapable of handling the disposition of that person's property, the Committee may direct payment of such benefit to the guardian, legal representative or person having the care and custody of such minor, incompetent or incapable person. The Committee may require proof of minority, incompetence, incapacity or guardianship, as it may deem appropriate prior to distribution of the benefit. Any payment of a benefit shall be a payment for the account of the Participant and the Participant's Beneficiary, as the case may be, and shall be a complete discharge of any liability under the Plan for such payment amount.

(a)General Compliance. The Plan is intended to qualify for an exclusion from, or satisfy the requirements governing the deferral of compensation under Section 409A of the Internal Revenue Code and any Treasury Regulations or other Internal Revenue Service guidance promulgated thereunder (collectively, the "409A Requirements"), as applicable.

(b)Specified Employees. Effective for Performance Units awarded on or after January 1, 2015, and notwithstanding any other provision of the Plan, if any payment or benefit provided to an Employee in connection with the Employee's termination of employment is determined to constitute "nonqualified deferred compensation" within the meaning of Section 409A and such Employee is determined to be a "specified employee" as defined in Section 409A(a)(2)(b)(i), then such payment or benefit shall not be paid until the first payroll date to occur following the six month anniversary of termination of employment or, if earlier, upon the Employee's death.
