HOW WE DETERMINE EXECUTIVE COMPENSATION
Our compensation vision is to provide compensation programs that drivepromote the achievement of our purpose-driven strategy, align executives’ and employees’ interests with the success of the Company, and provide competitive compensation opportunities to attract, retain and motivate a highly talented executive team and workforce. Our philosophy is to design compensation programs that drive high performance and reward that performance competitively within our industry. We believe that everyone should clearly understand their compensation and connection betweenhow it connects to individual and shareowner value.
The objectives for our executive compensation program are as follows:
•    Reward Strong Performance: motivate and reward executives to contribute to the achievement of our business and ESG-related objectives by aligning pay and performance through variable at-risk compensation
•    Align Executives’ and Shareowners’ Interests: align executive officers’ interests with those of our shareowners by delivering a significant proportion of total compensation through equity, tying a significant portion of our long-term performanceincentive pay directly to total shareowner return, tying compensation to meeting ESG metrics, and requiring executives to own Company stock
•    Maintain Consistency: drive sustainable performance and improvement by maintaining an appropriate level of executive compensation design consistency
Maintain•    Provide Competitive Positioning: attract and retain the best possible personnel through competitive compensation that is comparable to that of similar companies but driving what is right for our strategy and stakeholders

COMPENSATION DISCUSSION AND ANALYSIS
These compensation practices help us achieve our program objectives:
Performance-Based•    Incentive-Based At-Risk Compensation: a substantial portion of our executive officers’ compensation is based on achievement of performance goals, including ESG-based goals, with long-term equity-based awards delivering a majority of the performance-basedincentive-based pay
•    Equity Ownership: long-term incentive awards settle in Company stock, which, combined with our share ownership requirement, promotes executive officers have significant holdingsofficer ownership of our common stock
Minimized•    Minimize Systemic Risk-Taking: compensation programs are developed to properly mitigate unintended risk-taking, including by providing a mix of long-term and short-term compensation and using multiple performance criteria to determine awards
•    Market Compensation: total aggregate compensation levels are reviewed against market compensation levels which ensuresto ensure that we provide a competitive pay opportunity
•    Access to Retirement Programs: executive officers have access to retirement plans commonly in use among comparable companies, including deferred compensation plans, certain non-qualified retirement plans and 401(k) savings plans
The Compensation and Personnel Committee reconsidersconsiders these objectives and practices in its regular reviews of the executive compensation program.

The Compensation and Personnel Committee considers survey data, tenureexperience in a position, strategic importance, individual responsibilities and the competitiveness of the total compensation package when setting the long-term performance pay target.incentive opportunities. The target dollar value of the long-term equity awards areis determined prior to the grant date, and we grant the number of target shares or units necessary to approximate that dollar value based on the fair market value of our share price on the grant date.
1.    Performance Restricted Stock Units
Performance restricted stock The target units are intended to reward absolute long-term growth. Vestingallocated among the four different types of the performance restricted stock units is based on achieving compounded annual net income growth over a three-year performance periodawards as follows:

Below 4%0%
Vesting at target requires 5% compounded annual growth, which is based on the successful and timely execution of our strategic plan. The target is calculated based on achieving a compounded annual growth rate of 5% for a two-year period over projected 2019 consolidated net income from continuing operations, excluding certain items as permitted by the Amended and Restated 2010 Omnibus Incentive Plan, such as charges for reorganizing and restructuring, discontinued operations, asset write-downs, gains or losses on the disposition of an asset or business, mergers, acquisitions or dispositions and unusual or non-recurring items of gain or loss, in each case, as identifiedset forth in the Company's audited financial statements or periodic reports. Performance restricted stock units granted in 2019 will vest at target if our consolidated net income from continuing operations is $596.0 million as of the end of the three-year performance period. Performance restricted stock unit payouts are capped at 200% of the target payout. Performance restricted stock units are paid in Company stock.table above.
Any dividend equivalents credited on performance restricted stock units are treated as reinvested, but are not payable to the participant until the performance target is met and vesting is completed.

COMPENSATION DISCUSSION AND ANALYSIS

Performance restricted stock units have double-trigger acceleration upon a change in control. Upon a change in control, the awards vest at target and are valued based on the Company’s stock price as of the date immediately preceding the change in control date. The awards are paid at the end of the three-year vesting period provided the executive is still employed by the Company or had a qualifying termination event.
Adjusted net income for the period ended December 31, 2019 was $536.3 million, which exceeded the 7% three-year compounded annual growth for the performance period for the 2017 performance restricted stock units. As a result, our named executive officers earned 200% of the target award for the 2017-2019 performance period. Additional information about the performance restricted stock unit payouts for the 2017-2019 performance period is provided in the “2019 Option Exercises and Stock Vested” table.

The total shareowner return calculation represents the cumulative return for the three-year performance period reflecting price appreciation and reinvested dividend payments. Performance shares pay at target if our relative total shareowner return over three years is equal to the median performance of a specific peer group selected by the Compensation and Personnel Committee. TheConsistent with prior years, the committee selected the Edison Electric Institute (“EEI”)EEI Stock Index as the peer group for the 20192022 grants of performance shares as in previous years.shares. We believe the comparison to the EEI Stock Index appropriately assesses our performance relative to other publicly traded utilities. Performance share payouts are capped at 200% of the target payout.
Performance Earned performance shares granted in 2017 and 2018 are paid in shares of our common stock, cash or a combination of our common stock and cash, at the executives’ election. If the named executive officer chooses to take the payment in cash, the amount of the payout is determined by multiplying the number of shares earned by the stock value on a date chosen by the Compensation and Personnel Committee. The committee chooses this date in advance of issuing shares under the program, and it is typically the date immediately prior to payment. Performance shares granted in 2019 are paid in Company stock.
Any dividend equivalents credited on performance shares are treated as reinvested, but are not payable to the participant untilunless the performance target is met and vesting is completed.
Performance shares have double-trigger acceleration upon a change in control.

The awards are paid at the end of the three-year performance period provided the executive is still employed by the Company or had a qualifying termination event.
The total shareowner return for the 20172020 performance share grant (performance period ended on December 31, 2019)2022) ranked at the 72nd57th percentile relative to the peer group. As a result, our named executive officers earned 155.0%118% of the target award for the 2017-20192020-2022 performance period.

    Performance Restricted Stock Units - Net Income
Performance restricted stock units based on a net income metric are intended to reward absolute long-term growth in our profitability.

Performance restricted stock units granted in 2020 (performance period ended on December 31, 2022) had a net income target calculated based on achieving a cumulative consolidated net income from continuing operations over the performance period equated to a compounded annual growth rate of 5%, excluding certain items described above as permitted by the Amended and Restated 2010 Omnibus Incentive Plan. Cumulative consolidated net income for the performance period ended December 31, 2022 was $1.959 billion, which exceeded 7% three-year compounded annual growth of consolidated net income from continuing operations. As a result, our named executive officers earned 200% of the target award for the 2020-2022 performance period. Additional information about the payout of the performance restricted stock units for the 2020-2022 performance period is provided in the 2022 Option Exercises and Stock Vested table.
Performance Restricted Stock Units - Diversity
Performance restricted stock units based on DEI metrics are intended to reward successful implementation of our diversity efforts over time. Diversity performance restricted stock units were granted for the first time in 2022. Vesting of the performance restricted stock units is based on achieving a specified level of representation of women and people of color in our workforce over the three-year performance period as follows:
WomenPeople of Color
Percent of WorkforcePercentage of Target Value PayoutPercent of WorkforcePercentage of Target Value Payout
24.6%50%6.2%50%
25.2%100%7.1%100%
25.7%200%8.1%200%
Vesting at target requires growth in underrepresented populations in our workforce. Performance restricted stock units granted in 2022 will vest at target if women represent 25.2% of our workforce and people of color represent 7.1% of our workforce at the end of the performance period. Each target is equally weighted and measured independently. Performance restricted stock unit payouts are capped at 200% of the target payout.
    Service-based Restricted Stock Units
Service-based restricted stock units are time-vesting awards for which forfeiture restrictions lapse in a single installment after three years, subject to continuous employment.
Additional information about the restricted stock unit payouts for the 2017-20192020-2022 vesting period is provided in the “20192022 Option Exercises and Stock Vested”Vested table.
d.    Retirement and Other Benefits
We offer retirement and other benefit programs to our named executive officers that are consistent with those of our competitors.peers. We provide these benefits to remain competitive with the general market for executive officers. The benefit programs are designed to be competitive in attracting, retaining and motivating our named executive officers by providing competitive retirement benefits and incentivizing the promotion of the Company’s and shareowners’ interests over a long time horizon. A brief description of the plans is set forth in the table below.

BenefitDescription
Alliant Energy 
Deferred Compensation Plan
(“AEDCP”)(AEDCP)(1)
Enables participants to defer up to 100% of base salary and annual performanceincentive pay on a pre-tax basis and to receive earnings or incur losses on the deferrals until the date of distribution. The shares of Alliant EnergyCompany common stock identified as obligations under the AEDCP are held in a rabbi trust.
Alliant Energy
Cash Balance Pension Plan(2)
Offers flexible payment options and steady growth of retirement funds. The Cash Balance Pension Plan was frozen for participants effective August 2, 2008. Employees hired after December 25, 2005 are not eligible to participate.
Alliant Energy Corporation
401(k) Savings Plan
Provides for a match of $0.50 on each dollar for the first 8% of compensation contributed to the 401(k) Savings Plan account by the participants up to the IRS maximum. In addition, we contribute a percentage of participants’ salaries to their 401(k) accounts. The amount of the Company contribution ranges from 4% to 6% of a participant’s salary, depending on the participant’s age and number of years of service at the Company.
Alliant Energy
Excess Retirement Plan(2)

Provides the benefit that the participants would have earned under the Cash Balance Pension Plan and the Alliant Energy Corporation 401(k) Savings Plan but for statutory limitations on employer-provided benefits imposed on those tax-qualified plans and accruals earned on their deferrals into the AEDCP.
Alliant Energy
Supplemental Retirement Plan (“SRP”)(SRP)(2)
Generally provides retirement compensation in addition to the benefits provided by the Cash Balance Pension Plan and the 401(k) Savings Plan, which are limited by the Internal Revenue Code of 1986 (which we refer to as the tax(tax code), and the Alliant Energy Excess Retirement Plan.

(2)    See 2022 Pension Benefits below for more information regarding the Alliant Energy Cash Balance Pension Plan, the Excess Retirement Plan and the SRP.
The Compensation and Personnel Committee reviews benefit programs on a periodic basis to determine effectiveness and identify any necessary changes. Based on market data showing a trend away from SRPs, we do not anticipate providing SRP benefits to executives hired or promoted in 2013 or thereafter. The committee does not believe this change will inhibit our ability to attract and retain executive officers.
We provide limited perquisites to our named executive officers. Our named executive officers are eligible for executive physicals, reimbursement of financial planning expenses and long-term disability insurance which are in excess of the benefits provided to our other non-executive employees. The Compensation and Personnel Committee recognizes that the CEO’s job duties require significant travel and he or she is, therefore, permitted to use a corporate aircraft in some instances. From time to time, a family member or members may accompany the CEO on business trips.aircraft. For that reason,

e.    Mr. Luhrs was provided with a cash signing bonus which included two payments - a $250,000 bonus payable when he was hired and a $200,000 bonus payable in March 2024. Mr. Luhrs also was provided with a relocation package which includes reimbursement of expenses related to relocating to Madison, Wisconsin, and tax restoration payments for the relocation reimbursements. These sign-on awards were provided in consideration of forgone compensation from his previous employer and are an important part of his total compensation package, and were essential to our successful recruitment of Mr. Luhrs in a competitive market for talent in our industry. The awards are all subject to repayment terms in the event he terminates his employment within 24 months of receipt.
Post-Termination Compensation
1.    Key Executive Employment and Severance Agreements
We currently have in effect Key Executive Employment and Severance Agreements (“KEESAs”)(KEESAs) with our executive officers, including our named executive officers, and certain other key employees, which provide for double-trigger severance benefits under certain circumstances following a change in control.
Benefits under the KEESAs are paid ifonly if: (1) a change in control occurs and (2) a lossqualifying termination of employment occurs under certain circumstances within 180 days prior to the change in control or two years after the change in control. A qualifying termination occurs if the executive officer’s employment terminates as a result of (a) termination by the Company, other than by reason of death or disability or for cause, or (b) termination by the executive officer for good reason. This “double-trigger” double-trigger

COMPENSATION DISCUSSION AND ANALYSIS
mechanism ensures that only those executivesexecutive officers adversely affected by a change in control will receive benefits under the KEESA. KEESAs.
The KEESAs provide a cash termination benefit underpayment of 2.99 times for the KEESA is up toCEO, and for the other executive officers, two times the sum of (i) the executive officer’s (i) annual base salary and (ii) the greater of the officer’s target annual performanceincentive pay for the year in which the termination date occurs, oroccurs. The KEESAs also clarify that, consistent with the officer’s annual performance payterms of outstanding equity award agreements, any change in the year priorcontrol payments under outstanding equity awards will be paid pursuant to the change in control.terms of the equity plan and the agreements under which the awards were granted. We do not offer severance arrangements with executive officers that provide a multiplier equal to or greater than two.three.
The KEESAs are generally designed to avoid the adverse effects of Section 280G of the tax code. Each KEESA provides that if any portion of the benefits under the KEESA or under any other agreement would constitute an excess parachute payment for purposes of the tax code, the executive officer may receive the greater, on an after-tax basis, of either a payment $1 less than the maximum amount he or she may receive without becoming subject to the 20% excise tax or the fully calculatedfull payment subject to applicable excise taxes, for which the executive officer would be personally responsible. None of the KEESAs have Section 280G tax gross-up provisions.
We believe that the level of the benefits provided by the amended KEESAs to eachthe executive officerofficers reflects the appropriate amount of compensation necessary for our executive officers to consider our shareowners’ interests without potential influence of their personal interests. We believe the security afforded by the KEESAs will help the executives to remain focused on business continuity and will reduce the distraction of the executive’sexecutives’ reasonable concerns regarding future employment during the uncertainty of a proposed change in control transaction.
2.Additional information about the KEESAs is provided in the 2022 Potential Payments Upon Termination or Change in Control section.
    Executive Severance Plan
We also maintain the executive officer severance benefit plan, which compensates an executive officer in the event that his or her position is eliminated or significantly altered. As with our KEESA benefit, our executive officer severance benefit plan is designed to enable executives to remain focused on our business without undue personal concerns over job security. The plan provides for:
Severance pay equal to one year’s annual base salary
Up to 18 months of COBRA coverage or participation in our subsidized retiree medical insurance program if eligible (six months of which are paid by us)
Outplacement services and/or tuition reimbursement of up to $10,000
Access to our employee assistance program
Eligibility for benefits under this plan is conditioned upon an executive executing a severance agreement and release form. All severance packages of executive officers are approved by the Compensation and Personnel Committee. We believe our executive severance plan is consistent with industry-wide standards.
3.    Employment Agreements and Separation Arrangements
We do not have any other employment agreements or separation arrangements with our executive officers.

b.��   Process forFor Setting Executive Compensation
EntityRole
Compensation and Personnel Committee
The Compensation and Personnel Committee reviews and sets each component and level of compensation for the Company’s named executive officers and other executive officers.
The Compensation and Personnel Committee’s responsibilities include:
• Review and approval ofapprove executive officers’ compensation packages
• Review and approval ofapprove corporate incentive goals and objectives relevant to compensation
Evaluation ofEvaluate individual performance results in light of these goals and objectives
The Compensation and Personnel Committee is made up of independent directors and meets regularly in executive sessions without management present. The committee is supported in its work by the human resources staff and by the committee’s outside consultant.
Chief Executive Officer
The CEO recommends to the Compensation and Personnel Committee the level of compensation for the Company’s named executive officers and other senior Company executives, other than himself. The CEO considers the following factors when making his recommendations:
• Executive performance
TenureExperience in the role
• Strategic importance
• Internal pay equity
• Market data, as discussed below
• Information provided by the Company’s human resources staff
The CEO is present and available to the Compensation and Personnel Committee during their meetings with respect to the compensation of the Company’s other named executive officers and other executive officers. However, the committee discusses and determines the CEO’s compensation in executive session.
Independent Compensation ConsultantThe Compensation and Personnel Committee engaged Pay Governance LLC as its independent external advisor. The committee receives data, analyses and support from Pay Governance. During 2019,2022, Pay Governance participated in committee meetings, analyzed the competitive level of compensation for each of the named executive officers and provided information regarding executive compensation trends.trends and market practices. Pay Governance reports solely to the committee and meets with the committee at each meeting in executive session.
Market Data
Each year, Pay Governance prepares a market compensation analysis based on companies of similar size in terms of revenue and market capitalization, including those in the energy services industry and in general industry. This analysis assists the Compensation and Personnel Committee in establishing executive officer compensation levels to allow us to remain competitive in our market.
The market data used in 20192022 included two surveys:
• Willis Towers Watson’s 20182021 General Industry Executive Compensation Database, which includes pay data for approximately 1,000 general industry companies
• Willis Towers Watson’s 20182021 Energy Services Industry Executive Compensation Database which includes pay data for nearly all U.S. utilities.
Survey information was size-adjusted using regression analysis to correspond to each officer’s scope of responsibility.
The Compensation and Personnel Committee used equally blended general industry data and energy industry data to determine the market reference point used for corporate positions, which in 20192022 were held by Mr. Larsen, Mr. Durian, Mr. GallegosLuhrs and Ms. Kampling.Mr. Gallegos. Energy industry data was used as a secondary market reference point for these positions. Energy industry data
A defined utility peer group was used as the sole market reference point for utility-specific operating positions, such as those held by Mr. de Leon and Mr. Kouba. This peer group included: Atmos Energy Corp., Ameren Corp., Avista Corp., Black Hills Corp., CenterPoint Energy, Inc., CMS Energy Corp., Evergy, Inc., Eversource Energy, Hawaiian Electric Industries, Inc., IDACORP, Inc., MDU Resources Group, Inc., NiSource Inc., OGE Energy Corp., Pinnacle West Capital Corp., Portland General Electric Co., PPL Corp., Public Service Enterprise Group, Southwest Gas Holdings Inc., and WEC Energy Group, Inc.
The Compensation and Personnel Committee considered only aggregate data from these broad-based surveys and did not select any individual companies for comparison. Survey information was size-adjusted using regression analysis to correspond to each officer’s scope of responsibility. The survey data was updated to January 2019 using a 3% annual update factor, as 3% was the anticipated average annual compensation increase for the survey companies.
The surveymarket data provides market reference points at the 25th, 50th and 75th percentilepercentiles for each executive officer’s compensation components and total compensation. Generally, total aggregate compensation that falls within 15% of the median market reference point is considered to be at target. The aggregate total targeted compensation for all named executive officers fell within 15% of the applicable market reference point in 2019.2022.

Key Compensation Governance and Pay Practices
c.    Our executive compensation program emphasizes best practices in compensation design and governance practices, including:
Regular reviews of the program by the Compensation and Personnel CommitteePerformance metrics that encourage achievement of both absolute growth and relative growth
Double-trigger change in control provisions in our severance agreements and long-term equity awardsNo hedging or pledging of Company stock
Stock ownership guidelines for executive officersClawback policy that applies to our annual and long-term incentive pay plans
Dividends paid on equity awards only if performance targets are met or vesting is completedNo tax gross-up provisions in our change in control agreements
Maximum multiplier for change in control cash severance benefit no greater than 2.99All long-term equity awards settle in Company stock
Strong linkage of compensation to achievement of financial, customer-focused and ESG-related goalsLimited perquisites for our executive officers

Executive Stock Ownership Requirements
We require executives to own a certain number of shares of our common stock to further align the executives’ interests with those of our shareowners. The stock ownership guidelines are:
Officer LevelStock Ownership Guideline
Chief Executive Officer6 times base salary
President4 times base salary
Executive Vice President3.5 times base salary
Senior Vice President3 times base salary
Vice President1.5 times base salary
The required number of shares for each executive is determined by taking the preceding multiples of the executive’s base salary and dividing that amount by the closing price of our common stock as ofof: (i) January 2, 2019, (ii) the date of hire, or (iii) the date of promotion to a higher level of ownership requirement, whichever is later. We round that number to the nearest 500-share increment. The number of shares an executive is required to hold will not change unless the executive is promoted. Setting the required number of shares this way mitigates the effect of short-term volatility on compliance caused by changes in our stock price and by changes in salary.
Shares held outright, vested restricted stock vested restricted stock units, earned performance shares, earned performance restricted stock units, unvested restricted stock that vests solely on the passage of time, unvested restricted stock units that vest based solely on the passage of time, shares held in our AEDCP and shares held in the Alliant Energy Corporation 401(k) Savings Plan count toward the sharestock ownership requirement. Unearned performance restricted stock units and unearned performance shares do not count for this purpose.
Executives have five years from the date of their first long-term equity grants after the later of their hire date, or the date they were promoted into a position with a higher multiple, to achieve their goals. Executives are required to hold 100% of the after-tax value of vested performance restricted stock units until the share ownership guideline is met. Executives who have not met their sharestock ownership level after five years are required to retain 100% of the after-tax value of vested long-term equity awards until the share ownership requirement is met. The Company has not issued any stock options so there is no requirement to hold stock options after exercise. Our CEO retains the right to grant special dispensation for hardship, promotions or new hires.
AllOur CEO and all of our current named executive officers who have held their current positions for five years are in compliance with the sharestock ownership guidelines. The named executive officers who have been in their positions for less than five years including our CEO, are on track to achieve the above ownership goals. The shares owned by our named executive officers are shown in the “OwnershipOwnership of Voting Securities”Securities table.

ALLIANT ENERGY | 2023 Proxy Statement | 39


COMPENSATION DISCUSSION AND ANALYSIS
Clawback Policy
The Compensation and Personnel Committee adopted a clawback policy that applies to all cash and equity-based incentive compensation. Under the clawback policy, the committee will recoup compensation paid under the Company’s cash and equity incentive plans if it determines that such compensation was based on the achievement of financial or other results that were subsequently restated due to material noncompliance of the Company with any financial reporting requirement under the federal securities laws, and due in whole or in part to gross negligence, intentional misconduct or fraud of a current or former executive officer. If, in the committee’s view, the incentive-based compensation would have been materially lower if it had been based on the restated results, the committee will, to the extent permitted by applicable law, seek recoupment from that executive officer of any excess incentive compensation. Incentive compensation is also subject to clawback under applicable rules and regulations promulgated by the Securities and Exchange Commission and the national securities exchanges.
Prohibition on Hedging and Pledging
We prohibit the use of any hedging or similar transactions related to our shares by our executive officers and directors. We prohibit all “insiders”insiders from trading in puts, calls, options or other derivative securities related to the Company’s securities.securities. Other hedging transactions, such as short sales, zero-cost collars, prepaid variable forward sale contracts, equity swaps or similar transactions are also prohibited. Insiders are further prohibited from pledging Company securities. Insiders include all executive officers, all members of the Board of Directors and designated employees who receive material nonpublic information in the regular course of their duties.
e.    Compensation and Personnel Committee Risk Assessment
In December 2019,2022, the Compensation and Personnel Committee reviewed an assessment presented by management of our general compensation policies and practices for all employees, including those in our non-regulated businesses, to evaluate whether risks arising from these policies and practices were reasonably likely to have a material adverse effect on us. Based on this assessment, the committee concluded that our compensation policies and practices are not reasonably likely to have a material adverse effect on the Company and did not recommend or implement any material changes in 2019.changes. The committee believes that the following features of our policies and practices serve to mitigate material risks arising from our compensation policies and practices:
•    A mix of annual and long-term performance-basedincentive-based awards to provide an appropriate balance of short- and long-term risk and reward horizons
•    A variety of performance metrics for performanceincentive awards to avoid excessive focus on a single measure of performance

COMPENSATION DISCUSSION AND ANALYSIS

•    Caps on performanceincentive awards to reduce incentives to take short-term or inappropriately risky measures to increase payouts in any given year
•    Review of our compensation programs for reasonableness by our state utility commissions to mitigate risk
•    Clawback policies that provide us with the ability to recoup annual performanceand long-term incentive awards under appropriate circumstances
•    Stock ownership requirements for certain executives, including our named executive officers, that help to focus our executives on long-term stock price appreciation and sustainability
•    Robust compensation governance practices
f.    Role of Tax Considerations
Section 162(m) of the tax code limits the tax deductibility of compensation paid to our CEO and certain other executive officers to $1 million per person in any taxable year. Prior to changes to the tax code in December 2017, this limit did not apply to compensation that qualified as “performance-based”performance-based under Section 162(m). Effective for taxable years beginning after December 31, 2017, this exception has been repealed, unless the compensation qualifies for transition relief. New compensation awarded in the 2018 taxable year and thereafter in excess of $1 million per year generally will not be deductible, even if performance-based.
The Compensation and Personnel Committee, considers whether compensation will be deductible for federal tax purposes butconsistent with past practice, retains the flexibility and discretion to authorize compensation that will not be deductible, particularly as a result of the changes to Section 162(m) of the tax code.deductible. This flexibility is necessary to achieve elements of the Company’s success that are in areasthe best long-term interests of the Company and its shareowners, such as attracting and retaining talented executives and rewarding achievement of key corporate goals. Although the tax deduction exception for “performance-based” compensation is no longer available, the Compensation and Personal Committee continues to believe a significant portion of our executive compensation should be performance-based to align pay and performance and to create long-term value for our shareowners.

2022 CEO Pay Ratio
As required by SEC rules, we are providing the following information based on reasonable estimates.
For 2019,2022, the median of the annual total compensation of all employees (other than CEO) of the Company was $138,044.
In 2019, both Ms. Kampling and Mr. Larsen served in the role$100,691. The annual total compensation of CEO. We used our current CEO’s annualized compensation to calculate the CEO, pay ratio. To calculate our current CEO’s annualized compensation, we used the 2019 values reflectedas reported in the Summary Compensation Table except for salary where we used the annualized salary of $900,000. For purposes of calculating the CEO pay ratio only, the total CEO compensation used2022 above, was $7,765,384.$7,286,977.
The ratio of the annual total compensation of our CEO to the median of the annual total compensation of all employees for 20192022 was 5672 to 1.
As permitted by the SEC rules, the median employee utilized for 20192022 is the same employee identified in 2017 and 20182020 because there have been no changes in our employee population or employee compensation arrangements that we reasonably believe would result in a significant change to this pay ratio disclosure. To identify the “median employee”median employee from our employee population in 2017,2020, we compared the amount of salary and wages of our employees as reflected in our payroll records as reported to the IRS on Form W-2 for 2017.2020. We used December 31, 20172020 as the determination date. We did not consider annual equity awards in determining the median employee as such awards are not widely distributed to our employee population. We did not make any cost-of-living adjustments. We annualized the compensation of full-time employees who were hired in 2017.2020.
Once we identified our median employee, we calculated that employee’s compensation for 20192022 as though that compensation were being calculated for purposes of the Summary Compensation Table. We compared that compensation total with the annualized 20192022 compensation of our current CEO as described above.

b.    Alliant Energy Cash Balance Pension Plan
A portion of our salaried employees, including certain of our named executive officers, are eligible to participate in the Alliant Energy Cash Balance Pension Plan that we maintain. The Cash Balance Pension Plan bases a participant’s defined benefit pension on the value of a hypothetical account balance. For individuals participating in the Cash Balance Pension Plan as of August 1, 1998, a starting account balance was created equal to the present value of the benefit accrued as of December 31, 1997, under the applicable prior benefit formula. In addition, such individuals received a special one-time transition credit amount equal to a specified percentage varying with age and multiplied by credited service and pay. For 1998 through August 2, 2008, participants received annual credits to the account equal to 5% of base pay (including certain performanceincentive payments, pre-tax deferrals and other items). For 1998 through August 2, 2008, participants also received an interest credit on all prior accruals equal to 4%, plus a potential share of the gain on the investment return on Cash Balance Pension Plan assets for the year. We amended the Cash Balance Pension Plan’s interest crediting rate for 2009 and future years. The new interest crediting rate is equal to the annual percentage change in the consumer price index as of October each year, plus 3%.
Ms. Kampling’s benefit is determined under the Cash Balance Pension Plan formula. Mr. Gallegos isand Mr. Luhrs are not eligible to participate in the Cash Balance Pension Plan. For Mr. Larsen, Mr. Durian, Mr. de Leon, and Mr. Kouba, estimated benefits under the applicable prior plan benefit formula are expected to be higher than under the Cash Balance Pension Plan formula, utilizing current assumptions. Therefore, their benefits are determined under the applicable prior plan benefit formula. To the extent benefits under the Cash Balance Pension Plan are limited by tax law, any excess will be paid under the Excess Retirement Plan described below. Cash Balance Pension Plan accruals ceased as of August 2, 2008. This “freeze”freeze applies to both the 5% of base pay annual credits to the hypothetical account balance and to the grandfathered prior plan formulas. Subsequent to August 2, 2008, active participants receive enhanced benefits under the Alliant Energy Corporation 401(k) Savings Plan.
Pension benefits for Mr. Larsen and Mr. Durian are determined using the prior plan formula from the IES Industries pension plan. The prior plan formula provides retirement income based on years of service, final average compensation and Social Security covered compensation.
The monthly benefit formula for Mr. Larsen and Mr. Durian for service until the August 2, 2008 freeze date is A + B + C where: A= 1.05% of average monthly compensation for the number of years of service not in excess of 35; B = 0.50% of average monthly compensation in excess of Social Security covered compensation for the number of years of service not in excess of 35; and C = 1.38% of average monthly compensation for the number of years of service in excess of 35. Compensation generally is the salary amount reported in the Summary Compensation Table (subject to the limit in the tax code), with the final average compensation being calculated based on the three highest calendar years of such pay. The formula provides the basic benefit payable for the life of the participant. If the participant receives an alternative form of payment, then the monthly benefit would be reduced accordingly. Early retirement benefits are available after a participant reaches age 55, provided he has at least 15 years of service. Unreduced benefits are available at age 62. Benefits that commence prior to age 62 are reduced by a factor of not less than 5% per year.
Pension benefits for Mr. de Leon are determined using the prior plan formula from the WPL pension plan. The prior plan formula provides retirement income based on years of service, final average compensation and Social Security covered compensation.
The monthly benefit formula for Mr. de Leon for service until the August 2, 2008 freeze date is A - B x C where: A = 55% of average monthly compensation for the number of years of service not in excess of 30; B = 0.50% of average monthly compensation in excess of Social Security covered compensation; and C is credited service (up to 360 months) divided by 30. Compensation generally is the salary amount reported in the Summary Compensation Table (subject to the limit in the tax code), with the final average compensation being calculated based on the three highest calendar years of such pay. The formula provides the basic benefit payable for the life of the participant. If the participant receives an alternative form of payment, then the monthly benefit would be reduced accordingly. Early retirement benefits are available after a participant reaches age 55, provided he has at least 5five years of vesting service. Unreduced benefits are available at age 62. Benefits that commence prior to age 62 are reduced by a factor of not less than 5% per year.

EXECUTIVE COMPENSATION

Pension benefits for Mr. Kouba are determined using the prior plan formula from the IPC pension plan. The prior plan formula provides retirement income based on years of service and final average compensation.
ALLIANT ENERGY | 2023 Proxy Statement | 52


EXECUTIVE COMPENSATION
The monthly benefit formula for Mr. Kouba for service until the August 2, 2008 freeze date is A + B where: A = 1.17% of average monthly compensation for the number of years of service not in excess of 35 and B = 0.35% of average monthly compensation in excess of Social Security covered compensation. Compensation generally is the salary amount reported in the Summary Compensation Table (subject to the limit in the tax code), with the final average compensation being calculated based on the three highest calendar years of such pay. The formula provides the basic benefit payable for the life of the participant. If the participant receives an alternative form of payment, then the monthly benefit would be reduced accordingly. Early retirement benefits are available after a participant reaches age 55, provided he has at least 5 years of vesting service. Unreduced benefits are available at age 62. Benefits that commence prior to age 62 are reduced by a factor of not less than 3% per year.
c.    Alliant Energy Excess Retirement Plan
We maintain an unfunded Excess Retirement Plan that provides funds for payment of retirement benefits where an employee’s retirement benefits exceed statutory limits applicable to the tax-qualified plans. The Excess Retirement Plan provides an amount equal to the difference between (i) the actual pension benefit payable under the Cash Balance Pension Plan and our actual contributions based on age and service to the Alliant Energy Corporation 401(k) Savings Plan, and (ii) what such benefits and contributions would be if calculated without regard to any limitation imposed by the tax code on pension benefits or covered compensation.
d.    Alliant Energy Supplemental Retirement Plan
We maintain a legacy DB SRP and a legacy DC SRP, which provide additional retirement benefits if the executive remains with us until retirement, disability or death. The DB SRP is an unfunded, defined benefit retirement plan. The DC SRP is an unfunded, defined contribution plan. The DB SRP was discontinued in 2008. We also do not anticipate providing any DC SRP benefits to any executives hired or promoted in or after 2013. Mr. Larsen and Ms. Kampling participateparticipates in the DB SRP. Mr. Gallegos participates in the DC SRP. Mr. Durian, Mr. Luhrs, Mr. de Leon and Mr. Kouba do not participate in either the DB SRP or the DC SRP.
For Mr. Larsen, and Ms. Kampling, the DB SRP provides for payments in accordance with the formula A - (B(B + C + D)D) where: A = 50% of the participant’s average annual earnings (base salary plus annual performanceincentive pay) for the highest paid three consecutive years out of the last 10 years of the participant’s employment; B = benefits payable to the officer from the officer’s defined benefit plan; C = the aggregate Company contributions based on age and service to the Alliant Energy Corporation 401(k) Savings Plan; and D = the Excess Retirement Plan. The normal retirement date under the DB SRP is age 62 with at least 10 years of service; early retirement is at age 55 with at least 10 years of service and five or more years of continuous DB SRP employment. If a participant retires prior to age 62, the payment under the DB SRP is reduced by approximately 5% per year for each year the participant’s retirement date precedes his or her normal retirement date. This early retirement reduction factor is applied prior to any other offsets (described as B,, C,, or D above). Payment of benefits under the DB SRP commences six months after the participant’s retirement.
At the timely election of the participant, benefits under the DB SRP will be made in a lump sum, in annual installments over a period of five years, or in monthly installments for 18 years. Participants made their elections in December 2008. Participants may change their form of payment once, provided that the new election is made at least 12 months prior to their retirement. If such an election is made, benefits under the DB SRP will not be paid for five years after they otherwise would have been. If the monthly benefit is selected, and the participant dies prior to receiving 12 years of payments, payments continue to any surviving spouse or dependent children, payable for the remainder of the 12-year period. If the five annual installments benefit is selected and the participant dies prior to receiving five annual payments, payments will continue to any surviving spouse or dependent children, payable for the remainder of the five-year period. If the participant dies while still employed by us, the designated beneficiary will receive a lump sum equal to the discounted value of retirement benefits for 12 years. Ms. Kampling elected to receive her benefit payments in a lump sum commencing in January of 2020.
For Mr. Gallegos, the annual contribution credited to the DC SRP iswas equal to 12% of annual earnings, which consistsconsisted of base salary and annual performanceincentive pay earned for the year. An annual interest credit is earned on Mr. Gallegos’ account based on the annual investment return of a benchmark S&P 500 index fund. The normal retirement date under the DC SRP is age 55 with at least five years of continuous SRP employment. Payment of benefits under the DC SRP commences six months after the participant’s retirement. UponAt retirement, distributiondistributions from the plan isare made in five annual installments.

EXECUTIVE COMPENSATION

We maintain the Alliant Energy Deferred Compensation Plan (“AEDCP”)(AEDCP) under which participants, including our current named executive officers, may defer up to 100% of base salary and annual performanceincentive pay. Participants who have made the maximum allowed contribution to the Alliant Energy Corporation 401(k) Savings Plan may receive an additional credit from the Company to the AEDCP. The credit made in March 20192022 was equal to 50% of A - B,, where:
A = the lesser of (i) 8% of base salary for the plan year or (ii) the sum of the amounts (if any) contributed by the participant to the Alliant Energy Corporation 401(k) Savings Plan during the applicable year that were eligible for matching contributions under the Alliant Energy Corporation 401(k) Savings Plan, plus the amounts deferred by the participant during the applicable year under the AEDCP; and
B = the amount of any matching contributions under the Alliant Energy Corporation 401(k) Savings Plan on behalf of the participant for the applicable year.
The participant may elect to have his or her deferrals credited to an Interest Account, Equity Account, Company Stock Account or Mutual Fund Account. Deferrals and matching contributions to the Interest Account receive an annual return based on the 10-year Treasury Bond Rate plus 1.50%. Deferrals and matching contributions credited to the Equity Account are treated as invested in an S&P 500 index fund. Deferrals and matching contributions credited to the Mutual Fund Account are treated as invested in a mutual fund or other investment vehicle offered under the Alliant Energy Corporation 401(k) Savings Plan and selected by the participant. Deferrals and matching contributions credited to the Company Stock Account are treated as though invested in our common stock and are credited with dividend equivalents, which are treated as if reinvested. The shares of common stock identified as obligations under the AEDCP are held in a rabbi trust. Payments from the AEDCP due to death or retirement may be made in a lump sum or in annual installments for up to 10 years at the election of the participant. Payments from the AEDCP for any reason other than death or retirement are made in a lump sum. Participants are selected by our CEO. All of our current named executive officers are participants in the AEDCP. Ms. Kampling elected to receive her benefit paymentsAEDCP, except Mr. Gallegos who received a lump sum payment of his account balance in 1 to 10 annual installments commencing in January of 2020.  Remaining payments will be made in each January thereafter.2022.
We maintain a frozen legacy deferred compensation plan (the IES Deferred Compensation Plan), in which Mr. Larsen has a frozen account balance in the amount of $34,235$44,335 as of December 31, 2019.2022. An interest credit is provided for the balance in the account at aan annual rate of 11% for the balance in the account prior to July 1, 1993 and 9% on the remainder of the account.. This plan was frozen on April 21, 1998,21,1998, and since then, no amounts have been deferred to the account.

We are asking shareowners to approve the Alliant Energy Corporation 2020 Omnibus Incentive Plan (the “Plan”) to replace the Amended and Restated Alliant Energy Corporation 2010 Omnibus Incentive Plan (the “2010 Plan”) which expires on May 20, 2020. On the recommendationSection 14A of the Compensation and Personnel Committee,Securities Exchange Act of 1934 also provides shareowners the opportunity to indicate how frequently we should hold future advisory votes on the compensation of our named executive officers. Shareowners may indicate whether they prefer to have future advisory votes on executive compensation every year, every two years, every three years or abstain from voting on this proposal.
After careful consideration, the Board of Directors approvedrecommends that future advisory votes on the Plan and recommends approval by shareowners. The Plan is an important partcompensation of our pay-for-performance compensation program and long-term equity awards form a significant component of compensation for ournamed executive officers be held annually. Our Board believes that holding a vote every year is the most appropriate option because it enables our shareowners to provide us with input regarding the compensation of our named executive officers on a timely and employees. consistent basis. We have held annual advisory votes on executive compensation since 2011.
Shareowners are not voting to approve or disapprove the Board’s recommendation. Instead, shareowners are casting votes to recommend the frequency of future advisory votes on the compensation of our named executive officers by selecting one year, two years or three years, or abstaining from the vote.
The Planparticular frequency of this advisory vote receiving the greatest number of votes at the annual meeting (assuming a quorum is essential to rewarding strong performance, aligning executives’present) will be considered the shareowner recommendation for the frequency of the advisory vote on the compensation of our named executive officers. Abstentions and shareowners’ interests and maintaining a competitive compensation program. If shareowners do not approve the Plan, webroker non-votes will not have an equity plan under which we can make equity awards and, asconstitute a result, will be severely limited in our ability to achieve the foregoing goals.vote for any particular frequency.

No further awards can be granted under the 2010 Plan after its expiration date, and any shares previously available but not granted under the 2010 Plan as of its expiration date will not be issued, except upon vesting of awards that are outstanding under the 2010 Plan. As of March 9, 2020, 1,030,398 shares were subject to outstanding awards under the 2010 Plan and 6,151,395 shares remained available for new grants under the 2010 Plan (in each case basedthis advisory vote on the number of outstanding long-term awards at target which aggregate amount is 600,138 shares and which are subject to performance goals and dividend accumulation based on achieved performance).
Key Governance Practices

No liberal share recycling
No liberal “change in control” definition
No evergreen share feature
Double-trigger change in control vesting requirements
Minimum one-year vesting period for time-based awards (with limited exceptions)
No dividends paid on unvested awards
Limits on non-employee director cash and equity compensation

Except for adjustments permitted by the Plan, neither the Compensation and Personnel Committee nor any other person may, without shareowner approval, (i) decrease the exercise price of an option after it is granted; (ii) cancel an option when its exercise price exceeds the fair market value of the underlying shares, in exchange for cash, another option, restricted stock, or other equity award; or (iii) take any other action that is treated as a repricing under U.S. generally accepted accounting principles.
Eligibility. Awards may be granted under the Plan to officers (including executive officers) or other employees and consultants of the Company or its affiliates. Awards also may be granted to members of the Board of Directors of the Company. As of March 9, 2020, approximately 135 employees, including six executive officers and nine non-employee directors, were eligible to participate in the Plan.
Types of Awards. The Plan permits the granting of any or all of the following types of awards:
Restricted Stock, Restricted Stock Units and Share Awards.Restricted stock, restricted stock units and share awards may be subject to repurchase or forfeiture restrictions in the discretion of the Compensation and Personnel Committee. Restrictions may be based on continuous service with the Company or the achievement of performance goals over a performance period, as determined by the Compensation and Personnel Committee. Restricted stock units may be paid in cash, stock or a combination of stock and cash.
Performance Shares and Performance Units. Performance shares are awards valued by reference to a designated number of shares, and performance units are awards valued in relation to a unit that has a designated dollar value or the value of which is equal to the fair market value of one or more shares. Either type of award may be paid in cash, stock or a combination of stock and cash, subject in each case to the achievement of performance goals over a performance period established by the Compensation and Personnel Committee.
Other Stock or Cash-Based Awards. The Compensation and Personnel Committee may grant other incentives denominated in cash, shares or other property, subject to the terms of the Plan and any other terms and conditions determined by the Compensation and Personnel Committee.
Stock Options. Stock options may be designated as either nonqualified stock options or incentive stock options, which must comply with Section 422 of the tax code. The Compensation and Personnel Committee will determine the terms and conditions of options granted, including the vesting terms. The exercise price per share for options may not be less than the fair market value of a share of common stock on the grant date, except in the case of assumed or substituted options in acquisition transactions. Options have a maximum term of 10 years from the grant date, subject to earlier termination following a participant’s termination of service. Unless the Compensation and Personnel Committee determines otherwise, fair market value means, as of a given date, the closing price of our common stock.



OMNIBUS INCENTIVE PLAN PROPOSAL

Dividend or Dividend Equivalents.The Compensation and Personnel Committee may grant participants the right to receive dividend or dividend equivalent payments on equity-based awards. Any such dividend or dividend equivalent payments will be subject to the same restrictions on transferability and forfeitability that apply to the corresponding award. Dividends and dividend equivalents will be paid only if and to the extent the underlying award becomes vested or payable upon satisfaction of applicable service requirements and/or performance goals. Participants will not have a right to receive dividend payments or dividend equivalent payments with respect to shares of common stock subject to options.
Terms of Performance Awards
The Compensation and Personnel Committee may grant awards subject to the achievement of specified levels of one of more performance goals for the Company as a whole or an affiliate or business unit of the Company. Performance goals for awards may include, but are not limited to the following: net income, net earnings per share and total shareowner return.
In its discretion, the Compensation and Personnel Committee may adjust the performance goals applicable to an award granted to any participant to reflect such participant’s individual performance or such other factors as the committee may determine. If permitted under an award agreement, the committee will have the discretion, on the basis of such criteria as may be established by the committee, to reduce the amount otherwise payable pursuant to such award.
Prior to payment, the Compensation and Personnel Committee will determinereview and consider the amount payable under performance awards.
Limits on Awards. Subjectoutcome of this vote when making determinations as to certain adjustments, participants may not be granted awards in any calendar year with respect to more than 750,000 shares, andwhen the maximum dollar value payable to any participant with respect to performance units or other awards denominated in cash or other property cannot exceed $15,000,000 in any calendar year (measured at target for performance awards). In addition, the aggregate value of any compensation, both cash and equity, paid in any calendar year to any non-employee director will not exceed $750,000.
Adjustments: Change in Control. In the event of (i) a stock split, stock dividend, recapitalization or combination of shares, (ii) a merger or other transaction in which shares are changed or exchanged, or (iii) a cash dividend that exceeds 10% of the trading price of the shares (or similar special or extraordinary dividend event), then proportionate adjustments will be made to (A) the maximum number and/or kind of securities issuable under the Plan, including the maximum number and kind of securities issuable as incentive stock options, (B) the number and/or kind of securities subject to outstanding awards and the per share purchase or exercise price of such awards, (C) the maximum numbers and/or kinds of securities issuable to a participant, and (D) as applicable, the performance goals of outstanding awards. The Compensation and Personnel Committee also is authorized to make any of the foregoing adjustments if any other events occur that the Compensation and Personnel Committee determines requires an adjustment to prevent dilution or enlargement of benefits intended to be made available under the Plan.
In any of the foregoing events or in the event of a change in control, the Compensation and Personnel Committee may also (or in lieu of the foregoing) provide for a cash payment to the holder of an outstanding award in exchange for cancellation of all or a portion of the award. In addition, the committee is authorized to substitute, on an equitable basis as the committee determines, for each share then subject to an award, the number and kind of shares of stock, other securities, cash or other property to which holders of common stock are or will be entitled in respect of each share pursuant to the transaction (with appropriate adjustments with respect to any awards that have an exercise or purchase price).
Under the Plan, a “change in control” is generally deemed to have occurred if:
any person (with certain exceptions set forth in the Plan) is or becomes the beneficial owner of securities representing 30% or more of our outstanding shares of common stock or combined voting power;
a change in the composition of the majority of our Board of Directors occurs during a 12-month period that is not approved by at least two-thirds of the existing directors;
we consummate a merger, consolidation or share exchange with any other corporation (or issue voting securities in connection with a merger, consolidation or share exchange) in which our shareowners immediately prior to such transaction control less than 50% of the combined voting power after the merger, consolidation or share exchange; or
our shareowners approve, and we complete, a plan of complete liquidation or dissolution or the sale or disposition by us of all or substantially all of our assets (with certain exceptions set forth in the Plan).

OMNIBUS INCENTIVE PLAN PROPOSAL

The Compensation and Personnel Committee may, in connection with any merger, consolidation, acquisition of property or stock, or reorganization, and without affecting the number of shares of common stock otherwise reserved or available under the Plan, authorize the issuance or assumption of awards of an acquired entity upon terms it deems appropriate.
Minimum Vesting and Performance Periods. Awards that vest solely based on a participant’s continued employment or service require a minimum vesting period of one year of continuous service, except in connection with death, disability, retirement, change in control or other conditions as determined by the Compensation and Personnel Committee. The committee may grant awards that do not satisfy the minimum vesting schedule to non-employee directors, and to other employees, up to an aggregate of 5% of the shares reserved for issuance under the Plan with respect to employee grants, subject to adjustment as provided in the Plan.
Notwithstanding the foregoing, the Compensation and Personnel Committee may impose, at the time an award is granted or any later date, a shorter vesting and/or performance period than is otherwise required under the Plan to take into account a participant’s hire or promotion. In the event of a change in control of the Company, the Compensation and Personnel Committee may reduce the minimum vesting period only for participants who leave the Company for good reason or who are terminated by the Company for reasons other than cause.
Limited Transferability. Awards generally may not be transferred, except by will or the laws of descent and distribution, unless the transfer is approved by the Compensation and Personnel Committee and is for no consideration.
Clawback/Recoupment. Awards granted under the Plan are subject to recovery pursuant to any clawback requirements that the Compensation and Personnel Committee sets forth in the award agreement or any clawback policy that the Company adopts or is required to adopt under applicable law.
Term of Plan. Unless earlier terminated by the Board of Directors or the Compensation and Personnel Committee, the Plan will remain in effect until the tenth anniversary of shareowner approval of the Plan, which shareowner approval is expected to occur on May 21, 2020, or, if earlier, until all shares reserved for issuance have been issued.
Termination and Amendment. The Board of Directors or the Compensation and Personnel Committee may amend, alter, suspend, discontinue or terminate the Plan at any time, except that the Board of Directors must approve any amendment to the Plan if such approval is required by prior action of the Board or applicable law or regulation. Shareowners must approve any amendment to the Plan to the extent required by applicable law, regulation or stock exchange rule.
Certain U.S. Federal Income Tax Consequences. The following discussion briefly describes the material U.S. federal income tax consequences of the Plan generally applicable to the Company and to participants who are subject to U.S. federal taxation. The discussion is general in nature and does not address issues relating to the tax circumstances of any individual participant or any participant who is not subject to U.S. federal taxation. The discussion is basedadvisory vote on the tax code, applicable Treasury regulations and administrative and judicial interpretations thereof, each as in effect on the datecompensation of this proxy statement and is, therefore, subject to future changes in the law, possibly with retroactive effect. The discussion does not address the consequences of any estate, gift, state, local or foreign tax laws.
Stock Options.Generally, a participant will not recognize income at the time an option is granted or upon its vesting, provided the option has an exercise price at least equal to the fair market value of the common stock on the grant date and has no additional deferral feature. A participant who is granted a nonqualified stock option generally will recognize ordinary compensation income at the time of exercise in an amount equal to the excess of the fair market value of the shares at such time over the exercise price. Upon the participant’s subsequent disposition of the shares received with respect to such option, the participant will recognize a capital gain or loss (long-term or short-term, depending on how long the shares were held) to the extent the amount realized from the sale differs from the tax basis, i.e., the fair market value of the shares on the exercise date.
Generally, a participant will not recognize income at the time of exercise of an incentive stock option, except that the alternative minimum tax may apply. If the participant holds the shares of common stock acquired pursuant to the exercise of an incentive stock option for at least two years from the grant date of the incentive stock option and one year from the exercise date, then the participant will recognize a long-term capital gain or loss on the disposition of the shares equal to the difference between the amount the participant received in the disposition and the exercise price. If the participant fails to hold the shares for the holding periods set forth in the prior sentence, then the participant will recognize ordinary compensation income at the time of the disposition equal to the lesser of (i) the gain realized on the disposition and (ii) the excess of the fair market value of the shares of common stock on the exercise date over the exercise price. Any additional gain realized by the participant over the fair market value of the shares at the time of exercise will be treated as capital gain.
Restricted Stock. Generally, a participant will not recognize income at the time an award of restricted stock is made, unless the participant makes the election described below. A participant who has not made such an election will recognize

OMNIBUS INCENTIVE PLAN PROPOSAL

ordinary income at the time the restrictions on the stock lapse in an amount equal to the fair market value of the restricted stock at such time (less the amount, if any, the participant paid for such restricted stock). Any otherwise taxable disposition of the restricted stock after the time the restrictions lapse will result in a capital gain or loss (long-term or short-term, depending on the holding period) to the extent the amount realized from the sale differs from the tax basis, i.e., the fair market value of the common stock on the date the restrictions lapse. Dividends paid in cash and received by a participant prior to the time the restrictions lapse will constitute ordinary income to the participant in the year paid. Any dividends paid in stock will be treated as an award of additional restricted stock subject to the tax treatment described herein.
A participant may, within 30 days after the date of the award of restricted stock, elect to recognize ordinary income as of the date of the award in an amount equal to the fair market value of such restricted stock on the date of the award (less the amount, if any, the participant paid for such restricted stock). If the participant makes the election, then any cash dividends the participant receives with respect to the restricted stock will be treated as dividend income to the participant in the year of payment and will not be deductible by the Company. Any otherwise taxable disposition of the restricted stock (other than by forfeiture) will result in a capital gain or loss. If the participant who has made an election subsequently forfeits the restricted stock, then the participant will not be entitled to deduct any loss. In addition, the Company would then be required to include as ordinary income the amount of any deduction the Company originally claimed with respect to such shares.
Performance Shares. The grant of performance shares generally will not create income tax consequences for the Company or the participant on the date of grant. Upon the participant’s receipt of shares at the end of the applicable performance period, the participant will recognize ordinary income equal to the fair market value of the shares received, except that if the participant receives shares of restricted stock in payment of performance shares, recognition of income may be deferred in accordance with the rules applicable to restricted stock as described above. Upon the participant’s subsequent disposition of the shares, the participant will recognize capital gain or loss (long-term or short-term, depending on the holding period) to the extent the amount realized from the disposition differs from the shares’ tax basis, i.e., the fair market value of the shares on the date the participant received the shares.
Performance Units and Restricted Stock Units. The grant of a performance unit or restricted stock unit will not create income tax consequences to the Company or the participant on the date of grant. Upon the participant’s receipt of cash and/or shares at the end of the applicable performance or vesting period, the participant will recognize ordinary income equal to the amount of cash and/or the fair market value of the shares received. If performance units are settled in whole or in part in shares, upon the participant’s subsequent disposition of the shares, the participant will recognize a capital gain or loss (long-term or short-term, depending on the holding period) to the extent the amount realized upon disposition differs from the shares’ tax basis, i.e., the fair market value of the shares on the date the employee received the shares.
Tax Consequences to the Company. In the foregoing cases, the Company generally will be entitled to a deduction at the same time and in the same amount as a participant recognizes ordinary income, subject to any limitations imposed under the tax code.
Withholding. We are authorized to deduct or withhold from any award granted or payment due under the Plan, or require a participant to remit to us, the amount of any withholding taxes due in respect of the award or payment and to take such other action as may be necessary to satisfy all obligations for the payment of applicable withholding taxes. We are not required to issue any shares or otherwise settle an award under the Plan until all tax withholding obligations are satisfied.
Additional Taxes Under Section 409A. If an award under the Plan is considered non-qualified deferred compensation and such award is neither exempt from nor compliant with the requirements of Internal Revenue Code Section 409A, then the participant generally will be subject to an additional 20% income tax on the value of the award when it is no longer subject to a substantial risk of forfeiture, as well as interest on the income taxes that were owed from the date of vesting to the date such taxes are paid.
Limitation of Deduction. Section 162(m) of the tax code generally denies a tax deduction to any publicly held corporation for compensation paid to certain “covered employees” in a taxable year to the extent that such compensation paid to a covered employee exceeds $1 million.
No Guarantee of Tax Treatment. Notwithstanding any provision of the Plan, the Company does not guarantee that (i) any award intended to be exempt from Section 409A of the tax code is so exempt, (ii) any award intended to comply with Section 409A of the tax code does so comply, or (iii) any award will otherwise receive a specific tax treatment under any other applicable tax law, nor in any such case will the Company or any of its affiliates indemnify, defend or hold harmless any individual with respect to the tax consequences of any award.

(b)Delegation to Other Committees or Officers. To the extent applicable law permits, the Board may delegate to another committee of the Board, or the Board or the Committee may delegate to one or more officers of the Company, any or all of the authority and responsibility of the Committee with respect to this Plan; provided, however, that no such delegation is permitted with respect to Awards made to Section 16 Participants at the time any such delegated authority or responsibility is exercised unless the delegation is to another committee of the Board consisting entirely of Non-Employee Directors. If the Board or the Committee has made such a delegation, then all references to the Committee in this Plan include such other committee or one or more officers to the extent of such delegation.
(c)Repricing Prohibited. Notwithstanding any provision of this Plan to the contrary, and except for adjustments permitted by Section 13, the Committee shall not have the right, without shareowner approval, to (i) decrease the exercise price of an Option after it is granted; (ii) cancel an Option at a time when its exercise price exceeds the Fair Market Value of the underlying Shares, in exchange for cash, another option, restricted stock, or other equity award; or (iii) take any other action that is treated as a repricing under U.S. generally accepted accounting principles.

(e)Committee Determinations. All Committee determinations shall be made in the sole discretion of the Committee and are final, conclusive and binding on all interested parties.
SECTION 4. SHARES SUBJECT TO THIS PLAN
(a)Plan Reserve. Subject to adjustment as provided in Section 13, an aggregate of 9,000,000 Shares are available for issuance under this Plan. The Shares reserved for issuance may be either authorized and unissued Shares or Shares reacquired at any time and now or hereafter held as treasury stock.
(b)Share Usage. The aggregate number of Shares reserved under Section 4(a) shall be depleted on the date of grant of an Award by the maximum number of Shares, if any, with respect to which such Award is granted. If (i) an Award lapses, expires, terminates or is cancelled without the issuance of Shares under, or the payment of other compensation with respect to Shares covered by, the Award (whether due currently or on a deferred basis), (ii) it is determined during or at the conclusion of the term of an Award that all or some portion of the Shares with respect to which the Award was granted will not be issuable, or that other compensation with respect to Shares covered by the Award will not be payable, (iii) Shares are forfeited under an Award, or (iv) Shares are issued under any Award and the Company subsequently reacquires them pursuant to rights reserved upon the issuance of the Shares, then such Shares shall be recredited to this Plan’s reserve and may again be used for new Awards under this Plan. Notwithstanding the foregoing, in no event shall the following Shares be recredited to this Plan’s reserve; (A) Shares tendered or withheld to satisfy federal, state or local tax withholding obligations; (B) Shares tendered or withheld in payment of the exercise price of an Option; or (C) Shares purchased by the Company using proceeds from Option exercises.


2020 OMNIBUS INCENTIVE PLAN

(c)Subject to adjustment as provided in Section 13, no more than an aggregate of 2,000,000 Shares may be issued upon the exercise of Incentive Stock Options.
SECTION 5. ELIGIBILITY
An Award may be granted to any officer or other employee of the Company or its Affiliates, a consultant who provides services to the Company or its Affiliates, or a Director, including a Non-Employee Director; provided, however, that only employees of the Company or a Subsidiary may be granted Incentive Stock Options.
SECTION 6. AWARDS
(a)General. Subject to the terms of this Plan, the Committee shall have the authority, in its sole discretion, to determine the type or types of Awards to be granted under this Plan, the number of Shares subject to such Awards and the other terms of Awards. Awards may be granted alone or in addition to, or in substitution for, any other Award (or any other award granted under another plan of the Company or any Affiliate of the Company).
(b)Evidence of Awards. Awards granted under this Plan shall be evidenced by an Award Agreement.
(c)Individual Limitations.
(i)Limits on Awards to Participants. Subject to adjustment as provided in Section 13, no Participant may be granted Awards other than Performance Units or other Awards denominated in cash or other property in any calendar year with respect to more than 750,000 Shares for such Awards (measured at target with respect to grants of performance-based Awards), and the maximum dollar value payable with respect to Performance Units or other Awards denominated in cash or other property granted to any Participant in any one calendar year is $15,000,000.
(ii)Limits on Awards to Non-Employee Directors. Notwithstanding any provision of this Plan to the contrary, the aggregate value of cash compensation and the grant date fair value of Awards (computed as of the date of grant in accordance with applicable financial accounting rules) that may be granted or awarded during any calendar year to any Non-Employee Director, solely with respect to service as a Non-Employee Director, shall not exceed $750,000.
(iii)For purposes of the foregoing limits, Awards granted in previous calendar years shall not count against the Award limits in subsequent calendar years, even if the Awards from previous calendar years are earned, vest or are otherwise settled in calendar years following the calendar year in which they are granted.
(d)Minimum Vesting Period. Awards granted under this Plan that vest based on continuous service shall require a minimum vesting period of one year of continuous service, except in connection with death, Disability, retirement, Change in Control (subject to Section 6(e)) or other conditions as determined by the Committee. This minimum vesting schedule shall not apply to Substitute Awards or Awards to Non-Employee Directors. Notwithstanding this provision, up to 5% of the Shares reserved for issuance under this Plan, subject to adjustment as provided in Section 13, may be issued without a minimum vesting schedule.
(e)Waiver of Restrictions. Notwithstanding any provision of this Plan that requires a minimum vesting and/or performance period for an Award, the Committee, at the time an Award is granted or any later date, may subject an Award to a shorter vesting and/or performance period to take into account a Participant’s hire or promotion, or may accelerate the vesting or deem an Award to be earned, in whole or in part, in the event of a Participant’s death, Disability or retirement (as defined by the Committee) or a Change in Control. In the event of a Change in Control, such change may be made only for Participants who resign for Good Reason or whom the Company terminates for reasons other than Cause.
(f)Deferrals. To the extent permitted by applicable law, the Committee may permit or require a Participant to defer receipt of the payment of any Award. If any such deferral election is permitted or required, the Committee, in its sole discretion, shall establish rules and procedures for such payment deferrals, which may include the grant of additional Awards or provisions for the payment or crediting of interest or dividend equivalents, including converting such credits to deferred stock unit equivalents. All deferrals by Participants shall be made in accordance with Code Section 409A.
(g)Dividends and Dividend Equivalents. The Committee may grant an Award with provisions giving a Participant the right to receive any cash dividends (whether regular or otherwise), stock dividends, dividend equivalents and other distributions (whether paid in cash or securities) paid or made with respect to Awards; provided, however, that any such dividends, dividend equivalents or distributions shall be held in the custody of the Company and shall be subject to the same restrictions on transferability and forfeitability that apply to the corresponding Award, including that, with respect to Awards whose vesting or payment are dependent on the achievement of one or more Performance Goals, stock dividends, dividend equivalents and other distributions shall accrue and be paid only if and to the extent the Award becomes vested or payable; and provided further that the right to any dividends, dividend equivalents or other distributions declared and paid on an Award will be structured in a manner intended to be exempt from or comply with Code Section 409A. Except as otherwise provided

2020 OMNIBUS INCENTIVE PLAN

in the Award Agreement, all dividends, dividend equivalents or distributions credited to the Participant shall be paid to the Participant within 45 days following the full vesting of the Award with respect to which such dividends, dividend equivalents or distributions were made.
SECTION 7. OPTIONS
(a)The Committee may grant Options on such terms and conditions as it shall determine in its sole discretion, including, but not limited to, with respect to each Option: (i) whether the Option is an Incentive Stock Option or a Nonqualified Stock Option; (ii) the number of Shares subject to the Option; (iii) the per Share exercise price, which may not be less than the Fair Market Value of the Shares as of the date of grant of the Option (and not less than the minimum exercise price required by Code Section 422 with respect to Incentive Stock Options), except for Substitute Awards; (iv) the time or times at which the Option shall vest and become exercisable; (v) the permitted methods of payment of the exercise price of the Option and such other terms and procedures for exercise of the Option as may be required by the Committee; (vi) the effect of a Participant’s termination of employment or service on exercise of the Option; and (vii) the maximum term of the Option, which shall not exceed 10 years after the date of grant (unless a shorter term is required by Code Section 422 with respect to Incentive Stock Options). An Option may be exercised only for whole Shares.
(b)The exercise price for Shares purchased under an Option shall be paid to the Company by delivery of consideration equal to the product of the per Share exercise price and the number of Shares to be purchased. Such consideration must be paid before the Company will the issue the Shares being purchased and must be in a form or a combination of forms acceptable to the Committee for that purchase, which forms may include:
(i)cash, check or wire transfer;
(ii)having the Company withhold Shares that would otherwise be issued on exercise of the Option that have an aggregate Fair Market Value equal to the aggregate exercise price of the Shares being purchased under the Option;
(iii)tendering (either actually or, so long as the Shares are registered under Section 12(b) or 12(g) of the Exchange Act, by attestation) Shares owned by the Participant that have an aggregate Fair Market Value equal to the aggregate exercise price of the Shares being purchased under the Option;
(iv)so long as the Shares are registered under Section 12(b) or 12(g) of the Exchange Act, and to the extent permitted by law, delivery of a properly executed exercise agreement or notice, together with irrevocable instructions to a brokerage firm designated or approved by the Company to deliver promptly to the Company the aggregate amount of proceeds to pay the Option exercise price and any tax withholding obligations that may arise in connection with the exercise, all in accordance with the Federal Reserve Board; or
(v)such other consideration as the Committee may permit.
(c)Notwithstanding the foregoing, the terms of any Incentive Stock Option shall in addition comply in all respects with Code Section 422 and any applicable regulations thereunder, including, to the extent required thereunder, that if the aggregate Fair Market Value of Shares with respect to which Incentive Stock Options are exercisable for the first time by a Participant during any calendar year exceeds $100,000 (or, if different, the maximum limitation then in effect under the Code), such portion in excess of $100,000 shall be treated as a Nonqualified Stock Option.
SECTION 8. SHARE AWARDS, RESTRICTED STOCK, RESTRICTED STOCK UNITS, PERFORMANCE SHARES AND PERFORMANCE UNITS
The Committee may grant Awards of Shares, Restricted Stock, Restricted Stock Units, Performance Shares and Performance Units on such terms and conditions and subject to such repurchase or forfeiture restrictions, if any, as the Committee shall determine in its sole discretion, including those based on continuous service with the Company or an Affiliate of the Company or the achievement of any performance goals and which terms, conditions and restrictions shall be set forth in the Award Agreement. The Committee shall have the authority, in its sole discretion, to provide whether Performance Shares, Performance Units and Restricted Stock Units shall be settled in cash, in Shares (including Restricted Stock) or in a combination of cash and Shares.
SECTION 9. PERFORMANCE AWARDS
(a)Performance Goals. The Committee may grant Awards subject to the achievement of one or more objective performance goals established by the Committee, which may be based on the attainment of specified levels of one of or any combination of “performance criteria” for the Company as a whole or an Affiliate or business unit of the Company, as reported or calculated by the Company, including, but not limited to, the following: net income; net earnings per share (including diluted earnings per share); and total shareowner return (each a “Performance Goal”). Such Performance Goals also may be based on the achievement of specified levels of Company performance (or performance of an applicable Affiliate or

2020 OMNIBUS INCENTIVE PLAN

business unit of the Company) under one or more of the Performance Goals described above relative to the performance of other corporations. Performance Goals also may be based on individual goals. The performance period for any Award must relate to a period of at least one fiscal year of the Company, except that, if the Award is made at the time of commencement of employment with the Company or an Affiliate of the Company or on the occasion of a promotion, then the Award may relate to a period shorter than one fiscal year. Performance Goals may include a threshold, target, maximum and intermediate and other levels of performance, with the final payout value for an Award determined by the performance level attained during the applicable performance period.
(b)Determination and Payment of Awards. As soon as practicable following the completion of the performance period applicable to an Award, the Committee shall determine the extent to which the applicable Performance Goals have been attained and the final value of the Award earned by each Participant and to be paid upon the Award’s settlement in accordance with the terms of the applicable Award.
(c)Adjustments. In its discretion, the Committee may adjust the Performance Goals applicable to an Award granted to any Participant to reflect such Participant’s individual performance in his or her position with the Company or an Affiliate of the Company or such other factors as the Committee may determine. If permitted under an Award Agreement, the Committee shall have the discretion, on the basis of such criteria as may be established by the Committee, to reduce the amount otherwise payable pursuant to such Award.
SECTION 10. OTHER STOCK OR CASH-BASED AWARDS
Subject to the terms of this Plan and such other terms and conditions as the Committee deems appropriate, the Committee may grant other incentives denominated in cash, Shares, or other property under this Plan; provided, however, that any Award that provides for purchase rights shall be priced at no less than 100% of the Fair Market Value on the date of grant of the Award. The Committee shall have the authority, in its sole discretion, to determine that payment of cash-based Awards shall be paid in Shares or Restricted Stock, either on a mandatory basis or at the election of the Participant, having a Fair Market Value at the time of the payment equal to the amount payable with respect to the Award; provided, however, that any such determination by the Committee or election by the Participant must be made at such time and manner as determined by the Committee and will be subject to the terms of this Plan.
SECTION 11. WITHHOLDING
(a)General. The Company or any Affiliate of the Company may require the Participant to pay to the Company or any Affiliate of the Company, as applicable, (a) the amount of any taxes that the Company or any Affiliate of the Company is required by applicable federal, state, local or foreign law to withhold with respect to the grant, vesting, exercise or payment of an Award (“tax withholding obligations”) and (b) any amounts due from the Participant to the Company or any Affiliate of the Company (“other obligations”). Notwithstanding any other provision of this Plan to the contrary, the Company shall not be required to issue any Shares or otherwise settle an Award under this Plan until such tax withholding obligations and other obligations are satisfied.
(b)Tax Withholding Methods. The Committee may permit or require a Participant to satisfy all or part of the Participant’s tax withholding obligations and other obligations by (i) paying cash to the Company or an Affiliate of the Company, as applicable, (ii) having the Company or an Affiliate of the Company, as applicable, withhold an amount from any cash amounts otherwise due or to become due from the Company or an Affiliate of the Company, as applicable, to the Participant, (iii) having the Company withhold a number of Shares that would otherwise be issued to the Participant (or become vested, in the case of Restricted Stock) having a Fair Market Value equal to the tax withholding obligations and other obligations, or (iv) surrendering a number of Shares the Participant already owns having a value equal to the tax withholding obligations and other obligations. The value of the shares so withheld or tendered may not exceed the employer’s minimum required tax withholding rate or such other applicable rate as is necessary to avoid adverse treatment for financial accounting purposes.
SECTION 12. TRANSFERABILITY
Awards are not transferable other than by will or the laws of descent and distribution, unless and to the extent the Committee allows a Participant to (a) designate in writing a beneficiary to exercise the Award or receive payment under the Award after the Participant’s death; (b) transfer an Award to the former spouse of the Participant as required by a domestic relations order incident to a divorce; or (c) otherwise transfer an Award; provided, however, that with respect to clause (c) above, the Participant may not receive consideration for such a transfer of an Award.
SECTION 13. ADJUSTMENTS; CHANGE IN CONTROL
(a)Adjustment of Shares. In the event of (i) a change to the Shares by reason of any stock split, stock dividend, recapitalization or combination of shares, (ii) a merger or other transaction in which the Shares are changed or exchanged, or (iii) a cash dividend that exceeds 10% of the trading price of the Shares at the time the dividend is declared or any other dividend or other distribution on the Shares in the form of cash, or a repurchase of Shares, that the Board determines by

2020 OMNIBUS INCENTIVE PLAN

resolution is special or extraordinary in nature or that is in connection with a transaction that the Company characterizes publicly as a recapitalization or reorganization involving the Shares, then the Committee shall make proportional adjustments to (A) the maximum number and/or kind of securities issuable under this Plan, including with respect to Incentive Stock Options; (B) the number and/or kind of securities subject to outstanding Awards and the purchase or exercise price per Share of such Awards; (C) the maximum number and/or kinds of securities set forth in Section 6(c); and (D), as applicable, the Performance Goals of an Award. The Committee also shall be authorized to make any adjustments described in (A)-(D) of the foregoing sentence, in such manner as it may deem equitable, if any other event shall occur that, in the judgment of the Committee, necessitates an adjustment to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under this Plan and with respect to Options to preserve, without exceeding, the value of such Options. In the event of any such adjustments, the number of Shares subject to any Award payable or denominated in Shares must always be a whole number. Notwithstanding the foregoing, if the Company shall subdivide the Shares or the Company shall declare a stock split or stock dividend, and if no action is taken by the Committee, then the adjustments contemplated by this Section 13(a) that are proportionate shall nevertheless automatically be made as of the date of such subdivision of the Shares or stock split or stock dividend.
Notwithstanding the foregoing, the issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, for cash or property, or for labor or services rendered, either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, outstanding Awards.
(b)Cancellation or Substitution of Awards. In the event of any event described in Section 13(a) or a Change in Control, the Committee may also (or in lieu of the foregoing) make provision for a cash payment to the holder of an outstanding Award in exchange for the cancellation of all or a portion of the Award (without the consent of the holder of the Award) in an amount determined by the Committee effective as of such time as the Committee specifies (which may be the time such transaction or event is effective or as set forth in an Award Agreement). Without limitation, in the event of any event described in Section 13(a) or a Change in Control (other than any such transaction in which the Company is the continuing corporation and in which the outstanding Common Stock is not being converted into or exchanged for different securities, cash or other property, or any combination thereof), the Committee shall be authorized to substitute, on an equitable basis as the Committee determines, for each Share then subject to an Award, the number and kind of shares of stock, other securities, cash or other property to which holders of Common Stock are or will be entitled in respect of each Share pursuant to the transaction, with appropriate adjustments with respect to any Awards that have an exercise or purchase price. For the avoidance of doubt, nothing in this Section 13 requires that all outstanding Awards be treated similarly.
(c)Issuance or Assumption. Notwithstanding any other provision of this Plan, and without affecting the number of Shares otherwise reserved or available under this Plan, in connection with any merger, consolidation, acquisition of property or stock, or reorganization, the Committee may authorize the issuance of Substitute Awards in assumption of, or in substitution or exchange for, awards previously granted by an Acquired Entity upon such terms and conditions as it may deem appropriate.
SECTION 14. AMENDMENT AND TERMINATION
(a)Term of Plan. Unless the Board or the Committee earlier terminates this Plan, this Plan will terminate on the earlier of (i) the date that is 10 years from the Effective Date and (ii) the date when all Shares reserved for issuance have been issued; provided, however, that Incentive Stock Options may not be granted more than 10 years after the earlier of the date the Board approves this Plan and the date the shareowners approve this Plan (or any amendment to this Plan that constitutes the adoption of a new plan for purposes of Code Section 422).
(b)Termination and Amendment. The Board or the Committee may amend, alter, suspend, discontinue or terminate this Plan at any time. Notwithstanding the foregoing, (i) the Board must approve any amendment of this Plan to the extent the Company determines such approval is required by prior action of the Board or applicable law or regulation and (ii) shareowners must approve any amendment of this Plan to the extent required by applicable law, regulation or stock exchange rule.
(c)Amendment, Modification or Cancellation of Awards. Subject to the requirements of this Plan, the Committee may amend or modify any Award, in each case by mutual agreement between the Committee and the Participant or any other person(s) as may then have an interest in the Award, so long as any such action does not increase the number of Shares issuable under this Plan (except as permitted by Section 13). The Committee need not obtain the consent of the Participant (or other interested party) for any such action that is permitted by the provisions of Section 13(a) or Section 13(b) or for any such action to the extent that: (i) the action is deemed necessary by the Committee to comply with any applicable law or the listing requirements of any principal securities exchange or market on which the Shares are then traded; (ii) the action is deemed necessary by the Committee to preserve favorable accounting or tax treatment of any Award for the Company; (iii) the Committee determines that such action does not materially and adversely affect the value of an Award or

2020 OMNIBUS INCENTIVE PLAN

that such action is in the best interest of the affected Participant or any other person(s) as may then have an interest in the Award, or (iv) unilateral action by the Committee is permitted under Section 15(c) of this Plan.
(d)Survival of Authority and Awards. Notwithstanding the foregoing, the authority of the Board and the Committee under this Section 14 will extend beyond the date of this Plan’s termination. In addition, termination of this Plan will not affect the rights of Participants with respect to Awards previously granted to them, and all unexpired Awards will continue in force and effect after termination of this Plan except as they may lapse or be terminated by their own terms and conditions.
SECTION 15. SECTION 409A
(a)General. This Plan and Awards granted under this Plan are intended to be exempt from the requirements of Code Section 409A to the maximum extent possible, whether pursuant to the short-term deferral exception described in Treasury Regulation section 1.409A-1(b)(4), the exclusion applicable to stock options and certain other equity-based compensation under Treasury Regulation section 1.409A-1(b)(5), or otherwise. To the extent Code Section 409A is applicable to this Plan or any Award granted under this Plan, it is intended that this Plan and any Awards granted under this Plan comply with the deferral, payout and other limitations and restrictions imposed under Code Section 409A. Notwithstanding any other provision of this Plan or any Award granted under this Plan to the contrary, this Plan and any Award granted under this Plan shall be interpreted, operated and administered in a manner consistent with such intentions.
(b)Separation from Service; Six-Month Delay. Without limiting the generality of the foregoing, and notwithstanding any other provision of this Plan or any Award granted under this Plan to the contrary, with respect to any payments and benefits under this Plan or any Award granted under this Plan to which Code Section 409A applies, all references in this Plan or any Award granted under this Plan to the termination of the Participant’s employment or service are intended to mean the Participant’s “separation from service,” within the meaning of Code Section 409A(a)(2)(A)(i). In addition, if the Participant is a “specified employee,” within the meaning of Code Section 409A, then to the extent necessary to avoid subjecting the Participant to the imposition of any additional tax under Code Section 409A, amounts that would otherwise be payable under this Plan or any Award granted under this Plan during the six-month period immediately following the Participant’s “separation from service,” within the meaning of Code Section 409A(a)(2)(A)(i), shall not be paid to the Participant during such period, but shall instead be accumulated and paid to the Participant (or, in the event of the Participant’s death, the Participant’s estate) in a lump sum on the first business day after the earlier of the date that is six months following the Participant’s separation from service or the Participant’s death.
(c)Unilateral Amendment. Notwithstanding any other provision of this Plan to the contrary, the Committee, to the extent it deems necessary or advisable in its sole discretion, reserves the right, but shall not be required, to unilaterally amend or modify this Plan and any Award granted under this Plan so that the Award qualifies for exemption from or complies with Code Section 409A; provided, however, that the Committee makes no undertaking to preclude Code Section 409A from applying to Awards granted under this Plan.
(d)No Guarantee of Tax Treatment. Notwithstanding any provision of this Plan to the contrary, the Company does not guarantee to any Participant or any other person(s) with an interest in an Award that (i) any Award intended to be exempt from Code Section 409A shall be so exempt, (ii) any Award intended to comply with Code Section 409A or Code Section 422 shall so comply, or (iii) any Award shall otherwise receive a specific tax treatment under any other applicable tax law, nor in any such case will the Company or any Affiliate of the Company be required to indemnify, defend or hold harmless any individual with respect to the tax consequences of any Award.
SECTION 16. MISCELLANEOUS
(a)Employment and Service. The issuance of an Award shall not confer upon a Participant any right with respect to continued employment or service with the Company or any Affiliate of the Company, or the right to continue as a Director. Unless determined otherwise by the Committee, for purposes of this Plan and all Awards, the following rules shall apply:
(i)a Participant who transfers employment or service between the Company and its Affiliates, or between Affiliates, shall not be considered to have terminated employment or service;
(ii)a Participant who ceases to be a Non-Employee Director because he or she becomes an employee of the Company or an Affiliate of the Company shall not be considered to have ceased service as a Director with respect to any Award until such Participant’s termination of employment with the Company and its Affiliates;
(iii)a Participant who ceases to be employed by the Company or an Affiliate of the Company and immediately thereafter becomes a Non-Employee Director, a non-employee director of an Affiliate of the Company, or a consultant to the Company or any Affiliate shall not be considered to have terminated employment until such Participant’s service as a director of, or consultant to, the Company and its Affiliates has ceased; and


2020 OMNIBUS INCENTIVE PLAN

(iv)a Participant employed by or providing service to an Affiliate of the Company shall be considered to have terminated employment or service when such entity ceases to be an Affiliate of the Company.
(b)No Fractional Shares. No fractional Shares or other securities may be issued or delivered pursuant to this Plan, and the Committee may determine whether cash, other securities or other property will be paid or transferred in lieu of any fractional Shares or other securities, or whether such fractional Shares or other securities or any rights to fractional Shares or other securities will be canceled, terminated or otherwise eliminated.
(c)Unfunded Plan. This Plan is unfunded and does not create, and should not be construed to create, a trust or separate fund with respect to this Plan’s benefits. This Plan does not establish any fiduciary relationship between the Company and any Participant or other person. To the extent any person holds any rights by virtue of an Award granted under this Plan, such rights are no greater than the rights of the Company’s general unsecured creditors.
(d)Requirements of Law and Securities Exchange. The granting of Awards and the issuance of Shares in connection with an Award are subject to all applicable laws, rules and regulations and to such approvals by any governmental agencies or national securities exchanges as may be required. Notwithstanding any other provision of this Plan or any Award Agreement, the Company has no liability to deliver any Shares under this Plan or make any payment unless such delivery or payment would comply with all applicable laws and the applicable requirements of any securities exchange or similar entity, and unless and until the Participant has taken all actions required by the Company in connection therewith. The Company may impose such restrictions on any Shares issued under this Plan as the Company determines necessary or desirable to comply with all applicable laws, rules and regulations or the requirements of any national securities exchanges.
(e)Recoupment. Awards shall be subject to the requirements of (i) Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (regarding recovery of erroneously awarded compensation) and any implementing rules and regulations thereunder, (ii) similar rules under the laws of any other jurisdiction, (iii) any compensation recovery or clawback policies adopted by the Company to implement any such requirements and (iv) any other compensation recovery and clawback policies as may be adopted from time to time by the Company, all to the extent determined by the Committee in its discretion to be applicable to a Participant.
(f)Governing Law. This Plan, and all agreements under this Plan, will be construed in accordance with and governed by the laws of the State of Wisconsin, without reference to any conflict of law principles.
(g)Limitations on Actions. Any legal action or proceeding with respect to this Plan, any Award or any Award Agreement must be brought within one year (365 days) after the day the complaining party first knew or should have known of the events giving rise to the complaint.
(h)Construction.
