DESCRIPTION OF THE REGISTRANT’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934
The following description of the registrant's securities registered pursuant to Section 12 of the Securities Exchange Act of 1934 (the “Exchange Act”) is a summary and does not purport to be complete.  The terms “CMS Energy”, “we”, “our” and “us” as used herein refer to CMS Energy Corporation and not any of its subsidiaries.
Description of Capital Stock
The following description is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to CMS Energy’s Restated Articles of Incorporation, as amended (the “CMS Energy Articles”).
Authorized Shares
The authorized capital stock of CMS Energy consists of:
•350 million shares of common stock, par value $0.01 per share (“CMS Energy Common Stock”); and
•10 million shares of preferred stock, par value $0.01 per share (“Preferred Stock”).
At January 14, 2022, CMS Energy had 289,760,265 shares of CMS Energy Common Stock and 9,200 shares of Preferred Stock issued and outstanding.

Common Stock

Dividend Rights and Policy; Restrictions on Dividends
Dividends on CMS Energy Common Stock are paid at the discretion of the board of directors of CMS Energy based primarily upon the earnings and financial condition of CMS Energy.  Dividends are payable out of the assets of CMS Energy legally available therefor.
Dividends on capital stock of CMS Energy are limited by Michigan law to legally available assets of CMS Energy.  Distributions on CMS Energy Common Stock may be subject to the rights of the holders, if any, of any issued and outstanding series of Preferred Stock.
Michigan law prohibits payment of a dividend or a repurchase of capital stock if, after giving it effect, a corporation would not be able to pay its debts as they become due in the usual course of business, or its total assets would be less than the sum of its total liabilities plus, unless the CMS Energy Articles provide otherwise, the amount that would be needed, if the corporation were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution (including the rights of holders of preferred stock, if any).

Voting Rights
Each holder of CMS Energy Common Stock is entitled to one vote for each share of CMS Energy Common Stock held by such holder on each matter voted upon by the shareholders.  Such right to vote is not cumulative.  A majority of the votes cast by the holders of shares entitled to vote thereon is sufficient for the adoption of any question presented, except that certain provisions of the CMS Energy Articles relating to (i) the authorization, effectiveness or validity of a merger or consolidation of CMS Energy that would adversely affect the powers or special rights of CMS Energy Common Stock (either directly by amendment to the CMS Energy Articles or indirectly by requiring the holders of the CMS Energy Common Stock to accept or retain, in such merger or consolidation, anything other than shares of CMS Energy Common Stock or shares of the surviving or resulting corporation having, in either case, powers and special rights identical to those of the CMS Energy Common Stock prior to such merger or consolidation) require the vote or consent of the holders of a majority of all of the shares of CMS Energy Common Stock then outstanding, (ii) contested elections of directors require the vote of a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors and (iii) special shareholder meetings, the number of directors, vacancies on CMS Energy’s board of directors, the removal, indemnification and liability of CMS Energy’s board of directors and the requirements for amending these provisions may not be amended, altered, changed or repealed unless such amendment, alteration, change or repeal is approved by the affirmative vote of the holders of at least 75% of the outstanding shares entitled to vote thereon.
Under Michigan law, the approval of the holders of a majority of the outstanding shares of CMS Energy Common Stock would be necessary (1) to authorize, effect or validate the merger or consolidation of CMS Energy into or with any other corporation if such merger or consolidation would adversely affect the powers or special rights of CMS Energy Common Stock, and (2) to authorize any amendment to the CMS Energy Articles that would increase or decrease the aggregate number of authorized shares of CMS Energy Common Stock or alter or change the powers, preferences or special rights of the shares of CMS Energy Common Stock so as to affect them adversely.  The effect of these provisions and the related provisions described in the prior paragraph may be to permit the holders of a majority of the outstanding shares of CMS Energy Common Stock to block any such merger or amendment that would adversely affect the powers or special rights of holders of such shares of CMS Energy Common Stock.
Preemptive Rights
The CMS Energy Articles provide that holders of CMS Energy Common Stock will have no preemptive rights to subscribe for or purchase any additional shares of the capital stock of CMS Energy of any class now or hereafter authorized, or any Preferred Stock, bonds, debentures or other obligations or rights or options convertible into or exchangeable for or entitling the holder or owner to subscribe for or purchase any shares of capital stock, or any rights to exchange shares issued for shares to be issued.

2

Liquidation Rights
In the event of the dissolution, liquidation or winding up of CMS Energy, whether voluntary or involuntary, after payment or provision for payment of the debts and other liabilities of CMS Energy and after there shall have been paid or set apart for the holders of Preferred Stock the full preferential amounts (including any accumulated and unpaid dividends) to which they are entitled, the holders of CMS Energy Common Stock will be entitled to receive, on a per share basis, the assets of CMS Energy remaining for distribution to the holders of CMS Energy Common Stock.  Neither the merger or consolidation of CMS Energy into or with any other corporation, nor the merger or consolidation of any other corporation into or with CMS Energy nor any sale, transfer or lease of all or any part of the assets of CMS Energy, shall be deemed to be a dissolution, liquidation or winding up for the purposes of this provision.
Subdivision or Combination
If CMS Energy subdivides (by stock split, stock dividend or otherwise) or combines (by reverse stock split or otherwise) the outstanding shares of CMS Energy Common Stock, the voting and liquidation rights of shares of CMS Energy Common Stock will be appropriately adjusted so as to avoid any dilution in aggregate voting or liquidation rights.
Transfer Agent and Registrar
The transfer agent and registrar for CMS Energy Common Stock is Equiniti Trust Company d/b/a EQ Shareowner Services.
Listing
CMS Energy Common Stock is listed on the New York Stock Exchange and trades under the symbol “CMS.”
Exchanges
The CMS Energy Articles do not provide for either the mandatory or optional exchange or redemption of CMS Energy Common Stock.
Preferred Stock

The authorized Preferred Stock may be issued without the approval of the holders of CMS Energy Common Stock in one or more series, from time to time, with each such series to have such designation, powers, preferences and relative, participating, optional or other special rights, voting rights, if any, and qualifications, limitations or restrictions thereof, as shall be stated in a resolution providing for the issue of any such series adopted by CMS Energy’s board of directors. The CMS Energy Articles provide that holders of Preferred Stock will not have any preemptive rights to subscribe for or purchase any additional shares of the capital stock of CMS Energy of any class now or hereafter authorized, or any Preferred Stock, bonds, debentures or other obligations or rights or options convertible into or exchangeable for or entitling the holder 

3

or owner to subscribe for or purchase any shares of capital stock, or any rights to exchange shares issued for shares to be issued. The future issuance of Preferred Stock may have the effect of delaying, deterring or preventing a change in control of CMS Energy. Shares of Preferred Stock may be offered either separately or represented by depositary shares.

CMS Energy has designated a series of its Preferred Stock titled 4.200% Cumulative Redeemable Perpetual Preferred Stock, Series C (the “Series C Preferred Stock”), initially consisting of 9,200 shares ($230,000,000 aggregate liquidation preference). The following description summarizes certain terms and provisions of the Series C Preferred Stock, and is subject to and qualified in its entirety by reference to the certificate of designation creating the Series C Preferred Stock (the “Series C Certificate of Designation”).

Ranking

The Series C Preferred Stock ranks, with respect to dividend rights and distribution rights upon CMS Energy’s liquidation, winding-up or dissolution:

•senior to CMS Energy Common Stock and each other class or series of CMS Energy’s capital stock established after the original issue date of the Series C Preferred Stock, or July 1, 2021 (the “Initial Issue Date”), the terms of which do not expressly provide that such class or series will rank senior to or on parity with the Series C Preferred Stock as to dividend rights and distribution rights upon CMS Energy’s liquidation, winding-up or dissolution (the “Junior Stock”);

•on parity with each class or series of CMS Energy’s capital stock established after the Initial Issue Date the terms of which expressly provide that such class or series will rank on parity with the Series C Preferred Stock as to dividend rights and distribution rights upon CMS Energy’s liquidation, winding-up or dissolution (the “Parity Stock”);

•junior to each class or series of CMS Energy’s capital stock established after the Initial Issue Date the terms of which expressly provide that such class or series will rank senior to the Series C Preferred Stock as to dividend rights and distribution rights upon CMS Energy’s liquidation, winding-up or dissolution (the “Senior Stock”);

•junior to CMS Energy’s existing and future indebtedness and other liabilities; and

•structurally subordinated to all existing and future indebtedness and other liabilities of CMS Energy’s subsidiaries and capital stock of CMS Energy’s subsidiaries held by third parties, which means that creditors of CMS Energy’s subsidiaries and any third parties holding capital stock of CMS Energy’s subsidiaries will be paid from the assets of such subsidiaries before holders of the Series C Preferred Stock would have any claims to those assets.

Dividends

Subject to the rights of holders of any class or series of CMS Energy’s capital stock ranking senior to the Series C Preferred Stock with respect to dividends, holders of the Series C Preferred Stock are entitled to receive, when, as and if declared by CMS Energy’s board of directors, or an authorized committee thereof, out of funds legally available for payment, cash dividends at the rate per annum of 4.200% on the $25,000 liquidation preference per share of Series C Preferred Stock. Declared dividends on the Series C Preferred Stock are payable in arrears on January 15, April 15, July 15 and October 15 of each year, commencing on October 15, 2021 (each, a “Dividend Payment Date”). Dividends on the Series C Preferred Stock accumulate daily from and including the most recent date as to which dividends have been paid or, if no dividends have been paid, from the Initial Issue Date, without regard to whether funds are legally available for the declaration or payment of such dividends. Declared dividends are payable on the relevant Dividend Payment Date to holders of record of the Series C Preferred Stock as they appear on CMS Energy’s stock register at the close of business on the immediately preceding January 1, April 1, July 1 or October 1, as applicable (each, a “Record Date”). These Record Dates will apply regardless of whether a particular Record Date is a business day. If a Dividend Payment Date is not a business day, payment of declared dividends will be made on the next succeeding business day, without any interest, additional dividends, or other payment in lieu of interest or additional dividends accumulating with respect to this delay. 

A “Dividend Period” is the period from, and including, a Dividend Payment Date to, but excluding, the next Dividend Payment Date, except that the initial Dividend Period commenced on, and included, the Initial Issue Date. Dividends accumulating or payable on the Series C Preferred Stock for any Dividend Period (or portion thereof) are calculated on the basis of a 360-day year consisting of twelve 30-day months. Accumulations of dividends on shares of the Series C Preferred Stock do not bear interest or dividends on such accumulated amount.

Dividends on the Series C Preferred Stock accumulate (i) whether or not CMS Energy has earnings, (ii) whether or not the declaration or payment of such dividends would then be permitted under Michigan law, (iii) whether or not such dividends are declared and (iv) whether or not any agreements to which CMS Energy is a party prohibit the current declaration or payment of dividends, including any agreement relating to indebtedness. Accordingly, if CMS Energy’s board of directors, or an authorized committee thereof, does not declare a dividend on the Series C Preferred Stock payable in respect of any Dividend Period before the related Dividend Payment Date, such dividend will accumulate and an amount equal to such accumulated dividend will become payable out of funds legally available therefor upon CMS Energy’s liquidation, winding-up or dissolution (or earlier repurchase or redemption of such shares of Series C Preferred Stock), to the extent not paid prior to such liquidation, winding-up or dissolution or earlier repurchase or redemption, as the case may be.

No dividend will be declared or paid on, or any sum of cash set aside for the payment of dividends on, any outstanding shares of Series C Preferred Stock with respect to any Dividend Period unless all dividends for all preceding Dividend Periods have been declared and paid on, or 

5

a sufficient sum of cash has been set aside for the payment of such dividends on, all outstanding shares of Series C Preferred Stock.

So long as any share of the Series C Preferred Stock remains outstanding, no dividend or distribution will be declared or paid on CMS Energy Common Stock or any other Junior Stock, and no CMS Energy Common Stock or any other Junior Stock will be repurchased, redeemed or otherwise acquired for consideration by CMS Energy or any of its subsidiaries unless, in each case, all accumulated and unpaid dividends for all preceding Dividend Periods have been declared and paid, or a sufficient sum of cash has been set aside for the payment of such dividends, on all outstanding shares of the Series C Preferred Stock. The foregoing limitation does not apply to: (i) any dividend or distribution payable in shares of CMS Energy Common Stock or other Junior Stock, together with cash in lieu of any fractional share; (ii) repurchases, redemptions or other acquisitions of CMS Energy Common Stock or other Junior Stock in connection with the administration of any benefit or other incentive plan, including any employment contract, including, without limitation, (x) purchases to offset the share dilution amount pursuant to a publicly announced repurchase plan, provided that any purchases to offset the share dilution amount shall in no event exceed the share dilution amount, (y) the forfeiture of unvested shares of restricted stock or share withholdings or other surrender of shares to which the holder may otherwise be entitled upon exercise, delivery or vesting of equity awards (whether in payment of applicable taxes, the exercise price or otherwise), and (z) the payment of cash in lieu of fractional shares; (iii) purchases of fractional interests in shares of any CMS Energy Common Stock or other Junior Stock pursuant to the conversion or exchange provisions of such shares of other Junior Stock or any securities exchangeable for or convertible into shares of CMS Energy Common Stock or other Junior Stock; (iv) any dividends or distributions of rights or CMS Energy Common Stock or other Junior Stock in connection with a shareholders’ rights plan or any redemption or repurchase of rights pursuant to any shareholders’ rights plan; (v) repurchases of CMS Energy Common Stock or other Junior Stock pursuant to a contractually binding requirement to buy CMS Energy Common Stock or other Junior Stock existing prior to the preceding Dividend Period, including under a contractually binding stock repurchase plan; (vi) the deemed purchase or acquisition of fractional interests in shares of CMS Energy Common Stock or other Junior Stock pursuant to the conversion or exchange provisions of such shares or the security being converted or exchanged; (vii) the acquisition by CMS Energy or any of its subsidiaries of record ownership in CMS Energy Common Stock or other Junior Stock for the beneficial ownership of any other persons (other than CMS Energy or any of its subsidiaries), including as trustees or custodians, and the payment of cash in lieu of fractional shares; and (viii) the exchange or conversion of Junior Stock for or into other Junior Stock and the payment of cash in lieu of fractional shares. 

When dividends on shares of the Series C Preferred Stock with respect to any previously completed Dividend Period (A) have not been declared and paid in full or (B) have been declared but a sum of cash sufficient for payment thereof has not been set aside for the benefit of the holders thereof on the applicable Record Date, no dividends may be declared or paid on any Parity Stock unless dividends are declared on the shares of Series C Preferred Stock such that the respective amounts of such dividends declared on the shares of Series C Preferred Stock and such Parity Stock will bear the same ratio to each other as all accumulated dividends and all 

6

declared and unpaid dividends per share on the shares of Series C Preferred Stock and such Parity Stock bear to each other; provided, however, that any unpaid dividends will continue to accumulate. The foregoing limitation will not apply to (i) purchases of fractional interests in shares of Parity Stock pursuant to the conversion or exchange provisions of such shares of Parity Stock or any securities exchangeable for or convertible into shares of Parity Stock, (ii) the deemed purchase or acquisition of fractional interests in shares of Parity Stock pursuant to the conversion or exchange provisions of such shares or the security being converted or exchanged, (iii) the acquisition by CMS Energy or any of its subsidiaries of record ownership in Parity Stock for the beneficial ownership of any other persons (other than for CMS Energy or any of its subsidiaries), including as trustees or custodians, and the payment of cash in lieu of fractional shares, and (iv) the exchange or conversion of Parity Stock for or into other Parity Stock (with the same or lesser aggregate liquidation amount) or Junior Stock and the payment of cash in lieu of fractional shares.

Liquidation, Winding-Up or Dissolution

In the event of CMS Energy’s voluntary or involuntary liquidation, winding-up or dissolution, each holder of the Series C Preferred Stock will be entitled to receive a liquidation preference in the amount of $25,000 per share of Series C Preferred Stock (the “Series C Liquidation Preference”) (equivalent to $25.00 per depositary share), plus an amount (the “Series C Liquidation Dividend Amount”) equal to accumulated and unpaid dividends (whether or not declared) on such shares to, but excluding, the date fixed for liquidation, winding-up or dissolution, to be paid out of CMS Energy’s assets legally available for distribution to shareholders, after payment or provision for CMS Energy’s debts, obligations and liabilities, including debt and other liabilities owed to creditors, as required by applicable law, and to holders of shares of any class or series of CMS Energy’s capital stock ranking senior to the Series C Preferred Stock with respect to distribution rights upon CMS Energy’s liquidation, winding-up or dissolution and before any payment or distribution is made to holders of any Junior Stock (including, without limitation, CMS Energy Common Stock).

The Series C Liquidation Preference is subject to equitable adjustment whenever there shall occur a stock split, combination, reclassification or other similar event involving the Series C Preferred Stock.  Any such adjustment will be determined in good faith by CMS Energy’s board of directors, or an authorized committee thereof, and submitted by CMS Energy’s board of directors, or such authorized committee thereof, to the transfer agent.

If, upon CMS Energy’s voluntary or involuntary liquidation, winding-up or dissolution, the amounts payable with respect to (i) the Series C Liquidation Preference plus the Series C Liquidation Dividend Amount on the shares of Series C Preferred Stock and (ii) the liquidation preference of, and the amount of accumulated and unpaid dividends (to, but excluding, the date fixed for such liquidation, winding-up or dissolution) on, all other Parity Stock are not paid in full, the holders of the Series C Preferred Stock and all holders of any such other Parity Stock will share equally and ratably in any distribution of CMS Energy’s assets in proportion to their respective liquidation preferences and amounts equal to the accumulated and unpaid dividends to which they are entitled.

7

After the payment to any holder of Series C Preferred Stock of the full amount of the Series C Liquidation Preference and the Series C Liquidation Dividend Amount for each of such holder’s shares of Series C Preferred Stock, such holder of Series C Preferred Stock will have no right or claim to any of CMS Energy’s remaining assets. 

Neither the sale, lease or exchange of all or substantially all of CMS Energy’s assets, nor CMS Energy’s merger or consolidation into or with any other person or entity, will be deemed to be CMS Energy’s voluntary or involuntary liquidation, winding-up or dissolution.

The CMS Energy Articles, including the Series C Certificate of Designation, do not contain any provision requiring funds to be set aside to protect the Series C Liquidation Preference or the Series C Liquidation Dividend Amount.

Optional Redemption

CMS Energy may, at its option, redeem the Series C Preferred Stock:

•in whole or in part, from time to time, on or after July 15, 2026 at a redemption price in cash equal to $25,000 per share of Series C Preferred Stock (equivalent to $25.00 per depositary share); or

•in whole but not in part, at any time within 120 days after the conclusion of any review or appeal process instituted by CMS Energy following the occurrence of a Ratings Event (as defined herein), or, if no review or appeal process is available or sought with respect to such Ratings Event, at any time within 120 days after the occurrence of such Ratings Event, at a redemption price in cash equal to $25,500 per share of Series C Preferred Stock (102% of the liquidation preference of $25,000 per share) (equivalent to $25.50 per depositary share),

plus, in each case, all accumulated and unpaid dividends (whether or not declared) to, but excluding, the redemption date; provided that, notwithstanding the foregoing, if a redemption date for any shares of Series C Preferred Stock occurs subsequent to a Record Date and on or prior to the next succeeding Dividend Payment Date, then the full amount of accumulated and unpaid dividends (whether or not declared) on such shares of Series C Preferred Stock to, but excluding, such Dividend Payment Date will be paid on such Dividend Payment Date to the persons who were the holders of record of such shares at the close of business on such Record Date and such accumulated and unpaid dividends will not be paid or required to be paid on the redemption date and will not constitute a part of the redemption price of such shares. 

The redemption price is subject to equitable adjustment whenever there shall occur a stock split, combination, reclassification or other similar event involving the Series C Preferred Stock.  Any such adjustment will be determined in good faith by CMS Energy’s board of directors, or an authorized committee thereof, and submitted by CMS Energy’s board of directors, or such authorized committee thereof, to the transfer agent.

8

“Ratings Event” means that, and will be deemed to have occurred when, any nationally recognized statistical rating organization as defined in Section 3(a)(62) of the Exchange Act, or in any successor provision thereto, that then publishes a rating for CMS Energy (referred to herein as a Rating Agency) amends, clarifies or changes the criteria it uses to assign equity credit to securities such as the Series C Preferred Stock, which amendment, clarification or change results in:

•the shortening of the length of time the Series C Preferred Stock is assigned a particular level of equity credit by that Rating Agency as compared to the length of time the Series C Preferred Stock would have been assigned that level of equity credit by that Rating Agency or its predecessor on the Initial Issue Date; or

•the lowering of the equity credit (including up to a lesser amount) assigned to the Series C Preferred Stock by that Rating Agency as compared to the equity credit assigned by that Rating Agency or its predecessor on the Initial Issue Date.

Voting Rights

Holders of the Series C Preferred Stock do not have any voting rights except as described below and as otherwise from time to time specifically required by Michigan law. Without limitation to the foregoing, but subject to any limits and restrictions stated in the CMS Energy Articles, no vote or consent of the holders of the Series C Preferred Stock or the depositary shares will be required for the issuance of any additional shares of Series C Preferred Stock not exceeding the aggregate number of shares authorized in the Series C Certificate of Designation or related depositary shares.

Whenever dividends on any shares of the Series C Preferred Stock or any other class or series of Preferred Stock that ranks on parity with the Series C Preferred Stock as to payment of dividends, and upon which similar voting rights have been conferred and are exercisable, have not been declared and paid for the equivalent of six quarterly dividend payments, whether or not for consecutive Dividend Periods (a “Nonpayment Event”), the holders of the Series C Preferred Stock (voting as a single class together with holders of any and all other classes of authorized Preferred Stock having equivalent voting rights, whether or not the holders of such Preferred Stock would be entitled to vote for the election of directors if such default in dividends did not exist) will be entitled to vote as a single class for the election of a total of two additional members of CMS Energy’s board of directors (the “Preferred Directors”), provided that CMS Energy’s board of directors will at no time include more than two Preferred Directors. In that event, the number of directors on CMS Energy’s board of directors will automatically increase by two and, at the request of any holder of Series C Preferred Stock or other Preferred Stock with equivalent voting rights, a special meeting of the holders of Series C Preferred Stock and any other class or series of Preferred Stock that ranks on parity with Series C Preferred Stock as to payment of dividends and for which dividends have not been paid will be called for the election of the two directors (unless such request is received less than 90 days before the date fixed for the next annual or special meeting of the shareholders, in which event such election will be held 

9

at such next annual or special meeting of shareholders), followed by such election at each subsequent annual meeting. These voting rights will continue until full dividends have been paid regularly on the shares of the Series C Preferred Stock and any other class or series of Preferred Stock that ranks on parity with the Series C Preferred Stock as to payment of dividends for at least four consecutive quarterly Dividend Periods or their equivalent following the Nonpayment Event.

If and when full dividends have been paid regularly on the Series C Preferred Stock and any other class or series of Preferred Stock that ranks on parity with the Series C Preferred Stock as to payment of dividends for at least four consecutive quarterly Dividend Periods or their equivalent following a Nonpayment Event, the holders of the Series C Preferred Stock will be divested of the foregoing voting rights (subject to revesting in the event of each subsequent Nonpayment Event) and the term of office of each Preferred Director so elected will terminate and the number of directors on CMS Energy’s board of directors will automatically decrease by two. Any Preferred Director may be removed at any time without cause by the holders of record of a majority of the outstanding shares of the Series C Preferred Stock (together with holders of any and all other classes of authorized Preferred Stock having equivalent voting rights, whether or not the holders of such Preferred Stock would be entitled to vote for the election of directors if such default in dividends did not exist) when they have the voting rights described above. So long as a Nonpayment Event continues, any vacancy in the office of a Preferred Director (other than prior to the initial election of the Preferred Directors) may be filled by the written consent of the Preferred Director remaining in office or, if none remains in office, by a vote of the holders of the outstanding shares of Series C Preferred Stock (together with holders of any and all other class of authorized Preferred Stock having equivalent voting rights, whether or not the holders of such Preferred Stock would be entitled to vote for the election of directors if such default in dividends did not exist) to serve until the next annual meeting of shareholders. The Preferred Directors will each be entitled to one vote per director on any matter.

So long as any shares of the Series C Preferred Stock are outstanding, in addition to any other vote or consent of shareholders required by law or by the CMS Energy Articles, the affirmative vote or consent of the holders of not less than two-thirds of the total stated liquidation preference (excluding accumulated and unpaid dividends thereon, and premiums or other similar amounts, if any) of all outstanding shares of Series C Preferred Stock and all outstanding shares of any other series of Voting Preferred Stock (as defined herein) at the time outstanding and entitled to vote thereon, voting together as a single class, given in person or by proxy, either in writing without a meeting or by vote at an annual or special meeting of such shareholders, will be necessary for CMS Energy to effect:

(1)    any amendment of the CMS Energy Articles, including the Series C Certificate of Designation, so as to authorize, or increase the authorized amount of, any class or series of Senior Stock; 

(2)    any amendment of any provision of the CMS Energy Articles, other than the Series C Certificate of Designation, so as to adversely affect the special rights, preferences, privileges, restrictions, or voting powers of the Series C Preferred Stock; or

10

(3)    any consummation of a binding share exchange or reclassification involving the shares of the Series C Preferred Stock, or of a merger or consolidation of CMS Energy with or into another entity, unless in each case: (i) the shares of the Series C Preferred Stock remain outstanding or, in the case of any such merger or consolidation with respect to which CMS Energy is not the surviving or resulting entity (or the Series C Preferred Stock is otherwise exchanged or reclassified), are converted or reclassified into or exchanged for preferred stock of the surviving or resulting entity or its ultimate parent; and (ii) the shares of the Series C Preferred Stock that remain outstanding or such shares of preferred stock, as the case may be, have rights, preferences, privileges and voting powers that, taken as a whole, are not materially less favorable to the holders thereof than the rights, preferences, privileges and voting powers, taken as a whole, of the Series C Preferred Stock immediately prior to the consummation of such transaction;

provided, however, that, for the avoidance of doubt, (1) any increase in the amount of CMS Energy’s authorized but unissued shares of Preferred Stock, (2) any increase in the amount of the authorized Series C Preferred Stock or the issuance of any additional shares of the Series C Preferred Stock or related depositary shares or (3) the authorization or creation of any class or series of Parity Stock or Junior Stock, any increase in the amount of authorized but unissued shares of such class or series of Parity Stock or Junior Stock or the issuance of any shares of such class or series of Parity Stock or Junior Stock will be deemed not to adversely affect (or to otherwise cause to be materially less favorable) the rights, preferences, privileges, restrictions or voting powers of the Series C Preferred Stock and will not require the affirmative vote or consent of holders of the Series C Preferred Stock except as required pursuant to Michigan law.

If any amendment, share exchange, reclassification, merger or consolidation described above would adversely affect (or cause to be materially less favorable, as applicable) the rights, preferences, privileges, restrictions or voting powers of one or more but not all series of Voting Preferred Stock, then only the series of Voting Preferred Stock adversely affected (or the terms of which would be materially less favorable, as applicable) and entitled to vote will vote as a class in lieu of all other series of Voting Preferred Stock. “Voting Preferred Stock” means any series of Preferred Stock, other than the Series C Preferred Stock, ranking equally with the Series C Preferred Stock either as to dividends or to the distribution of assets upon CMS Energy’s liquidation, dissolution or winding-up and upon which voting rights similar to the voting rights of the Series C Preferred Stock in all material respects have been established for such series of Preferred Stock and which are exercisable at the time of any vote of the Preferred Stock.

Without the consent of the holders of the Series C Preferred Stock and related depositary shares, to the fullest extent permitted by applicable law and so long as such action does not adversely affect the special rights, preferences, privileges, restrictions or voting powers of the Series C Preferred Stock and related depositary shares, CMS Energy may amend, alter, supplement or repeal any terms of the Series C Preferred Stock, including by way of amendment to the Series C Certificate of Designation, for the following purposes:

11

•to cure any ambiguity or mistake, or to correct or supplement any provision contained in the Series C Certificate of Designation that may be defective or inconsistent with any other provision contained in such Series C Certificate of Designation;

•to make any provision with respect to matters or questions relating to the Series C Preferred Stock that is not inconsistent with the provisions of the CMS Energy Articles, including the Series C Certificate of Designation; or

•to waive any of CMS Energy’s rights with respect thereto.

In addition, without the consent of the holders of the Series C Preferred Stock or related depositary shares, to the fullest extent permitted by applicable law, CMS Energy may amend, alter, supplement or repeal any terms of the Series C Preferred Stock, including by way of amendment to the Series C Certificate of Designation, in order to conform the terms thereof to the description of the terms of the Series C Preferred Stock set forth under “Certain Terms of the Series C Preferred Stock” in the prospectus supplement related to the offering of the Series C Preferred Stock.

Maturity and Other Provisions

The Series C Preferred Stock is perpetual and does not have a maturity date. 

The Series C Preferred Stock is not subject to any mandatory sinking fund, retirement fund, purchase fund or other similar provisions. CMS Energy is not required to repurchase or redeem, or set aside funds to repurchase or redeem, the Series C Preferred Stock. Accordingly, the shares of the Series C Preferred Stock will remain outstanding indefinitely unless and until CMS Energy decides to repurchase or redeem them, whether in whole or in part.

The Series C Preferred Stock is not convertible into, or exchangeable for, shares of any other classes or series of capital stock or other securities. The holders of the Series C Preferred Stock have no preemptive or preferential rights to purchase or subscribe for capital stock, obligations, warrants or other securities of any class or series.

Transfer Agent and Registrar

The transfer agent and registrar for the Series C Preferred Stock is Equiniti Trust Company d/b/a EQ Shareowner Services.

Depositary Shares

The following description summarizes certain terms and provisions of the depositary shares relating to the Series C Preferred Stock, and is subject to and qualified in its entirety by reference to the deposit agreement, dated as of July 1, 2021 (the “Deposit Agreement”), among CMS Energy, Equiniti Trust Company d/b/a EQ Shareowner Services, as depositary, and the holders 

12

from time to time of the depositary receipts evidencing the depositary shares, and the form of depositary receipts, which contain the terms and provisions of the depositary shares.

General

CMS Energy’s depositary shares represent proportional fractional interests in shares of the Series C Preferred Stock. Each depositary share represents a 1/1,000th interest in a share of Series C Preferred Stock, and is evidenced by a depositary receipt. The shares of Series C Preferred Stock represented by depositary shares are deposited under the Deposit Agreement. Subject to the terms of the Deposit Agreement, each holder of a depositary share is entitled, through the depositary, in proportion to the applicable fraction of a share of Series C Preferred Stock represented by such depositary share, to all the rights and preferences of the Series C Preferred Stock represented thereby (including dividend, voting, redemption and liquidation rights). 

Dividends and Other Distributions

The depositary will distribute any cash dividends or other cash distributions received in respect of the deposited Series C Preferred Stock to the record holders of depositary shares relating to the underlying Series C Preferred Stock in proportion to the number of depositary shares held by such holders. The depositary will distribute any property received by it other than cash to the record holders of depositary shares entitled to those distributions, unless it determines that the distribution cannot be made proportionally among those holders or that it is not feasible to make a distribution. In that event, the depositary may, with CMS Energy’s approval, sell the property and distribute the net proceeds from the sale to the holders of the depositary shares in proportion to the number of depositary shares they hold. 

Record dates for the payment of dividends and other matters relating to the depositary shares will be the same as the corresponding Record Dates for the Series C Preferred Stock. The amounts distributed to holders of depositary shares will be reduced by any amounts required to be withheld by the depositary or by CMS Energy on account of taxes or other governmental charges.

Redemption of Depositary Shares

If CMS Energy redeems the Series C Preferred Stock represented by the depositary shares, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption of the Series C Preferred Stock held by the depositary. The redemption price per depositary share will be equal to 1/1,000th of the redemption price per share payable with respect to the Series C Preferred Stock, plus all accumulated and unpaid dividends (whether or not declared) to, but excluding, the applicable redemption date. Whenever CMS Energy redeems shares of Series C Preferred Stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing an interest in shares of Series C Preferred Stock so redeemed.

13

In case of any redemption of less than all of the outstanding depositary shares, the depositary shares to be redeemed will be selected by the depositary pro rata or in such other manner determined by the depositary to be equitable. In any such case, CMS Energy will redeem depositary shares only in increments of 1,000 shares and any multiple thereof.

The depositary will mail (or otherwise transmit by an authorized method) notice of redemption to holders of the depositary shares not less than 30 days, nor more than 60 days, prior to the date fixed for redemption of the Series C Preferred Stock and the depositary shares.

Voting the Series C Preferred Stock 

When the depositary receives notice of any meeting at which the holders of the Series C Preferred Stock are entitled to vote, the depositary will deliver the information contained in the notice to the record holders of the depositary shares relating to the Series C Preferred Stock. Each record holder of the depositary shares on the record date, which will be the same date as the Record Date for the Series C Preferred Stock, may instruct the depositary to vote the amount of the Series C Preferred Stock represented by the holder’s depositary shares. To the extent possible, the depositary will vote the amount of the Series C Preferred Stock represented by depositary shares in accordance with the instructions it receives. CMS Energy agrees to take all reasonable actions that the depositary determines are necessary to enable the depositary to vote as instructed. If the depositary does not receive specific instructions from the holders of any depositary shares representing an interest in the Series C Preferred Stock, it will vote all depositary shares of that series held by it proportionately with instructions received.

Amendment and Termination of the Deposit Agreement 

The form of depositary receipt evidencing the depositary shares and any provision of the Deposit Agreement may be amended by agreement between CMS Energy and the depositary. However, any amendment that materially and adversely alters the rights of the existing holders of depositary shares or would be materially and adversely inconsistent with the rights of holders of the Series C Preferred Stock will not be effective unless such amendment has been approved by the record holders of depositary shares representing at least the amount of the depositary shares then outstanding necessary to approve any amendment that would alter or abrogate the special rights of the Series C Preferred Stock. CMS Energy may terminate the Deposit Agreement with the consent of holders of a majority of then outstanding depositary shares. The Deposit Agreement will automatically terminate if all outstanding depositary shares have been redeemed or if there has been made a final distribution in respect of the Series C Preferred Stock in connection with CMS Energy’s liquidation, dissolution or winding-up, and such distribution has been made to the holders of depositary shares.

Listing

The depositary shares are listed on the New York Stock Exchange and trade under the symbol “CMSPRC.”

Primary Source of Funds of CMS Energy; Restrictions on Sources of Dividends

The ability of CMS Energy to pay (i) dividends on its capital stock and (ii) its indebtedness, including the CMS Energy debt securities, depends and will depend substantially upon timely receipt of sufficient dividends or other distributions from its subsidiaries, in particular Consumers Energy Company (“Consumers”) and CMS Enterprises Company (“Enterprises”). Each of Consumers’ and Enterprises’ ability to pay dividends on its common stock depends upon its revenues, earnings and other factors. Consumers’ revenues and earnings will depend substantially upon rates authorized by the Michigan Public Service Commission. 

CMS Energy has pledged the common stock of Consumers as security for certain bank credit facilities. Consumers’ Restated Articles of Incorporation (the “Consumers Articles”) provide two restrictions on its payment of dividends on its common stock. First, prior to the payment of any common stock dividend, Consumers must reserve retained earnings after giving effect to such dividend payment of at least:

•$7.50 per share on all then outstanding shares of its preferred stock; and
•$7.50 per share on all then outstanding shares of all other stock over which its preferred stock do not have preference as to the payment of dividends and as to assets. 

Second, dividend payments during the 12-month period ending with the month the proposed payment is to be paid are limited to:

•50% of net income available for the payment of dividends during the Base Period (as defined below), if the ratio of common stock and surplus to total capitalization and surplus for 12 consecutive calendar months within the 14 calendar months immediately preceding the proposed dividend payment (the “Base Period”), adjusted to reflect the proposed dividend, is less than 20%; and

•75% of net income available for the payment of dividends during the Base Period, if the ratio of common stock and surplus to total capitalization and surplus for the 12 consecutive calendar months immediately preceding the proposed dividend payment, is at least 20% but less than 25%. 

The Consumers Articles also prohibit the payment of cash dividends on its common stock if Consumers is in arrears on preferred stock dividend payments. 

Provisions of the Federal Power Act and the Natural Gas Act appear to restrict dividends payable by Consumers to the amount of Consumers’ retained earnings. Several decisions from the Federal Energy Regulatory Commission suggest that under a variety of circumstances common stock dividends from Consumers would not be limited to amounts in Consumers’ retained earnings. Any decision by Consumers to pay common stock dividends in excess of retained earnings would be based on specific facts and circumstances and would result only after a formal regulatory filing process.

15

In addition, Michigan law prohibits payment of a dividend if, after giving it effect, Consumers or Enterprises would not be able to pay its respective debts as they become due in the usual course of business, or its respective total assets would be less than the sum of its respective total liabilities plus, unless the respective articles of incorporation permit otherwise, the amount that would be needed, if Consumers or Enterprises were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution. Currently, it is Consumers’ target to pay annual dividends equal to 80% of its annual consolidated net income, as, if and when declared by Consumers’ board of directors. Consumers’ board of directors reserves the right to change this target at any time.

Description of Debt Securities
The following description is a summary and does not purport to be complete. It is subject to and qualified in its entirety by reference to the indenture dated June 1, 1997 between CMS Energy and The Bank of New York Mellon, as trustee, as supplemented by the applicable supplemental indenture governing each particular series of junior subordinated notes issued thereunder (as so supplemented, as applicable, the “indenture”).
CMS Energy has three series of junior subordinated notes issued and outstanding and registered under Section 12 of the Exchange Act:  5.625% Junior Subordinated Notes due 2078 (“CMS-A”), the 5.875% Junior Subordinated Notes due 2078 (“CMS-C”) and the 5.875% Junior Subordinated Notes due 2079 (“CMS-D”), collectively, the “Notes”.  The Notes were issued under and are governed the indenture.  This summary is subject to and qualified in its entirety by reference to all of the provisions of the indenture and the Notes, including definitions of certain terms used in the indenture and the Notes. References herein to the term “indenture” mean the indenture, as supplemented, for the particular series of Notes being described.
Principal, Maturity and Interest
•We initially issued $200 million aggregate principal amount of CMS-A, which remains the aggregate principal amount outstanding.
•We initially issued $250 million aggregate principal amount of CMS-C, which remains the aggregate principal amount outstanding.
•We initially issued $630 million aggregate principal amount of CMS-D, which remains the aggregate principal amount outstanding.
Certain Provisions Relating to CMS-A:
The Notes mature on March 15, 2078 unless earlier redeemed. The Notes bear interest at a rate of 5.625% per year. Interest is payable quarterly in arrears on March 15, June 15, September 15 and December 15 of each year, subject to deferral as described below under “Provisions Relating to All Notes - Deferral of Interest Payments”. We will pay interest to holders of record at 5:00 p.m., New York City time, in whose name the applicable Note is 

16

registered at the close of business on the date (whether or not such day is a business day) fifteen calendar days immediately preceding the applicable interest payment date, except that interest payable at stated maturity shall be paid to the person or entity to whom the principal amount is paid. So long as the Notes are in book-entry form, principal of and premium and interest on the Notes will be payable, and the Notes may be transferred, only through the facilities of DTC. Interest on the Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months and, for any period shorter than a quarter, on the basis of the actual number of days elapsed per 30-day month.
Optional Redemption
The Notes will be redeemable at CMS Energy’s option, in whole or in part, at any time and from time to time, on or after March 15, 2023 at a redemption price equal to 100% of the principal amount of such Notes being redeemed, plus accrued and unpaid interest, if any, thereon to, but not including, the redemption date.
In addition, the Notes will be redeemable at CMS Energy’s option, at any time before March 15, 2023, in whole but not in part, at any time within 90 days following the occurrence and continuation of a Tax Event (as defined below). In such case, the redemption price will be equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest, if any, thereon to, but not including, the redemption date. See “Redemption Following a Tax Event” below.
The Notes will also be redeemable at CMS Energy’s option, at any time before March 15, 2023, in whole but not in part, at any time within 90 days following the conclusion of any review or appeal process instituted by us following the occurrence and continuation of a Rating Agency Event (as defined below). In such case, the redemption price will be equal to 102% of the principal amount of the Notes, plus accrued and unpaid interest, if any, thereon to, but not including, the redemption date. See “Redemption Following a Rating Agency Event” below.  
Redemption Following a Tax Event 
We will have the right to redeem the Notes, at any time before March 15, 2023, in whole but not in part, at any time within 90 days following the occurrence and continuation of a Tax Event at a redemption price equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest, if any, thereon to, but not including, the redemption date. A “Tax Event” means that CMS Energy has received an opinion of nationally recognized independent tax counsel experienced in such matters at any time after the occurrence of any of the events set forth below to the effect that, as a result of:
•any amendment to or change or announced proposed change in the laws or regulations of the United States or any of its political subdivisions or taxing authorities affecting taxation;

17

•any amendment to or change in an interpretation or application of such laws or regulations by any legislative body, court, governmental agency or regulatory authority; or
•any official administrative interpretation or official administrative pronouncement that provides for a position with respect to those laws or regulations that differs from the generally accepted position on the date of the Notes are issued; 
which amendment or change becomes effective or proposed change, pronouncement, interpretation, action or decision is announced on or after March 5, 2018, there is more than an insubstantial risk that interest payable on the Notes is not or within 90 days of the date of the opinion would not be deductible as such interest accrues, in whole or in part, by us for United States federal income tax purposes.
Our right to redeem the Notes due to a Tax Event is subject to the condition that, if we have the opportunity to eliminate a Tax Event, within 90 days following the occurrence and continuation of such Tax Event, by taking some ministerial action (a “ministerial action”), such as filing a form or making an election, or pursuing some other similar reasonable measure that will have no adverse effect on us or the holders of the Notes and will involve no material cost, we will pursue such measures in lieu of redemption. We cannot redeem the Notes while we are pursuing any such ministerial action.
Redemption Following a Rating Agency Event
We will have the right to redeem the Notes, at any time before March 15, 2023, in whole but not in part, at any time within 90 days following the conclusion of any review or appeal process instituted by us at any time following the occurrence and continuation of a Rating Agency Event, at a redemption price equal to 102% of the principal amount of the Notes, plus accrued and unpaid interest, if any, thereon to, but not including, the redemption date.
For purposes of CMS-A, “Ratings Agency Event” means a change in the methodology published by any nationally recognized statistical rating organization within the meaning of Section 3(a)(62) of the Exchange Act (a “rating agency”) that currently publishes a rating for CMS Energy in assigning equity credit to securities such as CMS-A, as such methodology is in effect on March 5, 2018 (the “current criteria for CMS-A”), which change results in a lower equity credit being assigned by such rating agency to CMS-A as of the date of such change than the equity credit that would have been assigned to CMS-A as of the date of such change by such rating agency pursuant to its current criteria for CMS-A.
Certain Provisions Relating to CMS-C:
The Notes mature on October 15, 2078 unless earlier redeemed. The Notes bear interest at a rate of 5.875% per year. Interest is payable quarterly in arrears on January 15, April 15, July 15 and October 15 of each year, subject to deferral as described below under “Provisions Relating to All Notes - Deferral of Interest Payments”. We will pay interest to holders of record at 5:00 p.m., New York City time, in whose name the applicable Note is registered at the close of business on 

18

the date (whether or not such day is a business day) fifteen calendar days immediately preceding the applicable interest payment date, except that interest payable at stated maturity shall be paid to the person or entity to whom the principal amount is paid. So long as the Notes are in book-entry form, principal of and premium and interest on the Notes will be payable, and the Notes may be transferred, only through the facilities of DTC. Interest on the Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months and, for any period shorter than a quarter, on the basis of the actual number of days elapsed per 30-day month.
Optional Redemption
The Notes will be redeemable at CMS Energy’s option, in whole or in part, at any time and from time to time, on or after October 15, 2023 at a redemption price equal to 100% of the principal amount of such Notes being redeemed, plus accrued and unpaid interest, if any, thereon to, but not including, the redemption date.
In addition, the Notes will be redeemable at CMS Energy’s option, at any time before October 15, 2023, in whole but not in part, at any time within 90 days following the occurrence and continuation of a Tax Event (as defined below). In such case, the redemption price will be equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest, if any, thereon to, but not including, the redemption date. See “Redemption Following a Tax Event” below.
The Notes will also be redeemable at CMS Energy’s option, at any time before October 15, 2023, in whole but not in part, at any time within 90 days following the conclusion of any review or appeal process instituted by us following the occurrence and continuation of a Rating Agency Event (as defined below).

Provisions Relating to All Notes:
We may issue debt securities from time to time in one or more series under the indenture. There is no limitation on the amount of debt securities we may issue under the indenture. The indenture does not limit our ability to incur additional indebtedness. The covenants contained in the indenture would not necessarily afford holders of Notes protection in the event of a highly leveraged transaction or other transaction involving us that may adversely affect the holders. In addition, the indenture and the terms of the Notes do not permit the holders of Notes to require us to repurchase the Notes in the event we undergo a change of control or similar transaction.
Ranking
The Notes are unsecured obligations and rank subordinate and junior in right of payment, to the extent set forth in the Indenture, to all of our existing and future senior indebtedness, which may include senior indebtedness issued under the indenture. Because we are a holding company, 

22

our obligations on the Notes will be effectively subordinated to the existing and future indebtedness and other liabilities of our subsidiaries.
As of December 31, 2019, CMS Energy had outstanding approximately $2.3 billion aggregate principal amount of senior indebtedness (secured and unsecured). As of December 31, 2019, our subsidiaries had outstanding approximately $9.8 billion aggregate principal amount of indebtedness, all of which would be effectively senior to the Notes.
Subordination
The Notes are our unsecured obligations and will rank subordinate and junior in right of payment in full, to the extent set forth in the indenture, to all Senior Indebtedness (as defined below) of CMS Energy. Because we are a holding company, our obligations on the Notes will be effectively subordinated to existing and future indebtedness and other liabilities of our subsidiaries.
If CMS Energy defaults in the payment of principal of, or interest or premium on, any Senior Indebtedness when it becomes due and payable or in the event any judicial proceeding is pending with respect to any such default, then, unless and until the default is cured or waived or ceases to exist, CMS Energy cannot make a payment with respect to the principal of, or interest or premium on, the Notes or acquire any Notes. In addition, upon the maturity of any Senior Indebtedness by lapse of time, acceleration or otherwise, CMS Energy cannot make a payment with respect to the principal of, or interest or premium on, the Notes or acquire any Notes unless and until all principal of, and interest and premium on, such Senior Indebtedness has been paid in full or such payment has been duly provided for in cash in a manner satisfactory to the holders of such Senior Indebtedness. The provisions of the indenture described in this paragraph, however, do not prevent CMS Energy from making payments in CMS Energy capital stock or in warrants, rights or options to acquire CMS Energy capital stock.
If there is any dissolution, winding up, liquidation, reorganization, bankruptcy, insolvency or similar proceeding with respect to CMS Energy, its creditors or its property, then all Senior Indebtedness must be paid in full before any payment (or any distribution of assets, in cash, property or securities) may be made to any holders of the Notes. The consolidation of CMS Energy with, or the merger of CMS Energy into, another corporation or the liquidation or dissolution of CMS Energy following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in the indenture shall not be deemed a dissolution, winding up, liquidation or reorganization for purposes of the subordination provisions of the indenture, if such other corporation, as part of such consolidation, merger, conveyance or transfer, complies with the conditions under the indenture.
If the trustee or any holder of Notes receives any payment or distribution on account of the Notes after the occurrence of an event described in the prior two paragraphs but before all of such affected Senior Indebtedness is paid in full (or any applicable declaration of acceleration thereof shall have been rescinded or annulled or any applicable such payment default shall have been cured or waived or cease to exist), then that payment or distribution shall be paid over and 

23

delivered to the holders of our Senior Indebtedness at the time outstanding until such Senior Indebtedness is paid in full (other than money or government obligations previously deposited in trust with the trustee in connection with the satisfaction and discharge of the indenture).
The holders of the Notes will be subrogated to the rights of the holders of our Senior Indebtedness to receive payments or distributions applicable to the Senior Indebtedness until all amounts owing on the Notes shall be paid in full.
The holders of our Senior Indebtedness may, at any time and from time to time, without the consent of or notice to the trustee or the holders of the Notes, without impairing or releasing the subordination provided in the indenture:
•change the manner, place or terms of payment or extend the time of payment of, or renew or alter, such Senior Indebtedness, or otherwise amend or supplement in any manner such Senior Indebtedness or any instrument evidencing the same or any agreement under which such Senior Indebtedness is outstanding;
•sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing such Senior Indebtedness;
•release any person liable in any manner for the collection for such Senior Indebtedness; or
•exercise or refrain from exercising any rights against CMS Energy and any other person.
The failure to make a payment on account of principal of or interest or premium on the Notes by reason of the subordination provisions of the indenture shall not be construed as preventing the occurrence of an event of default with respect to the Notes. The failure to make any payment on the Notes due to the subordination provisions in the indenture shall not impair the absolute and unconditional obligation of CMS Energy to pay to the holders of the Notes the principal of, and interest and premium on, the Notes as and when the same shall become due and payable in accordance with their terms. Nothing in the indenture (i) is intended to or shall affect the relative rights of the holders of Notes and the creditors of CMS Energy other than holders of Senior Indebtedness or (ii) shall prevent the trustee or any holder of Notes from exercising all remedies otherwise permitted by applicable laws upon default, subject to the rights of holders of Senior Indebtedness in respect of cash, property or securities of CMS Energy received upon exercise of such remedy.
With respect to the Notes, “Senior Indebtedness” means the principal of and premium, if any, and interest on the following, whether outstanding on the date of execution of the indenture or thereafter incurred, created or assumed:
•indebtedness of CMS Energy for money borrowed by CMS Energy or evidenced by debentures, notes, bankers’ acceptances or other corporate debt securities, or similar 

24

instruments issued by CMS Energy (in each case, other than the Notes or any other subordinated debt securities);
•all capital lease obligations of CMS Energy;
•all obligations of CMS Energy issued or assumed as the deferred purchase price of property, all conditional sale obligations of CMS Energy and all obligations of CMS Energy under any title retention agreement (but excluding trade accounts payable arising in the ordinary course of business);
•obligations with respect to letters of credit;
•all indebtedness of others of the type referred to in the four preceding bullet points assumed by or guaranteed in any manner by CMS Energy or in effect guaranteed by CMS Energy;
•all obligations of the type referred to in the five preceding bullet points of other persons secured by any lien on any property or asset of CMS Energy (whether or not such obligation is assumed by CMS Energy) (subject to certain exceptions); or
•renewals, extensions or refundings of any of the indebtedness referred to in the preceding six bullet points unless, in the case of any particular indebtedness, renewal, extension or refunding, under the express provisions of the instrument creating or evidencing the same or the assumption or guarantee of the same, or pursuant to which the same is outstanding, such indebtedness or such renewal, extension or refunding thereof is not superior in right of payment to the Notes (or any other subordinated debt securities).
The indenture does not limit the total amount of Senior Indebtedness that may be issued. 
Registration, Transfer and Exchange 
The Notes will be initially issued in the form of one or more notes in registered, global form, without coupons, in denominations of $25 and integral multiples in excess thereof. The global Notes will be registered in the name of the nominee of The Depository Trust Company (“DTC”). Except in limited circumstances, owners of beneficial interests in a global Note will not be entitled to have Notes registered in their names, will not receive or be entitled to receive physical delivery of any such Note and will not be considered the registered holder thereof under the indenture.
Deferral of Interest Payments
So long as there is no event of default under the indenture with respect to the Notes, we may defer interest payments on the Notes for a period of up to 40 consecutive quarterly periods (each such period, commencing on the date that the first such interest payment would otherwise have been made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the maturity of the Notes. During this period, the interest on the Notes will still 

25

accrue at their applicable interest rate. In addition, interest on the deferred interest will accrue at an annual rate equal to the interest rate on the applicable Notes, compounded quarterly, to the extent permitted by law.
Before the end of any Optional Deferral Period that is shorter than 40 consecutive quarterly periods, we may further defer the period, so long as the entire Optional Deferral Period does not exceed 40 consecutive quarterly periods or extend beyond the maturity or redemption date, if earlier, of the Notes. We may also elect to shorten the length of any Optional Deferral Period. Once we have paid all accrued and unpaid interest on the Notes after the conclusion of any Optional Deferral Period, we may elect to begin a new Optional Deferral Period.
If we defer payment on the Notes or there has occurred and is continuing an event of default applicable to the Notes or any event of which we have actual knowledge that is, or with the giving of notice or the lapse of time, or both, would be an event of default applicable to the Notes, neither we nor our majority-owned subsidiaries may:
•declare or pay any dividend or distribution on CMS Energy capital stock;
•redeem, purchase, acquire or make a liquidation payment with respect to any CMS Energy capital stock (which includes common stock and preferred stock);
•make any payment of principal of or interest or premium, if any, on or repay, repurchase or redeem any CMS Energy indebtedness that is equal in right of payment with or junior in right of payment to the Notes; or
•make any guarantee payments with respect to any CMS Energy guarantee of indebtedness of our subsidiaries or any other party that is equal in right of payment with or junior in right of payment to the Notes.
However, during an Optional Deferral Period or such event of default described above, we may:
•pay dividends or distributions payable solely in shares of our capital stock or rights to acquire, repurchase or redeem our capital stock; 
•declare any dividend in connection with the implementation of a plan providing for the issuance by us to all holders of our capital stock of rights entitling them to subscribe for or purchase such capital stock, which rights (1) are deemed to be transferred with such capital stock, (2) are not exercisable and (3) are also issued in respect of future issuances of capital stock, in each case until the occurrence of a specified event or events (a “Rights Plan”);
•issue any of our shares of capital stock under any Rights Plan or redeem or repurchase any rights distributed pursuant to a Rights Plan;
•reclassify our capital stock or exchange or convert one class or series of our capital stock for another class or series of our capital stock;

26

•purchase fractional interests in shares of our capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged; and
•purchase or acquire capital stock related to the issuance of capital stock or rights under our dividend reinvestment plan or any of our benefit plans for our directors, officers, employees, consultants or advisors.
We will give the holders of the Notes and the trustee notice of our election or any shortening or extension of the Optional Deferral Period at least ten business days prior to the earlier of (1) the next succeeding interest payment date or (2) the date upon which we are required to give notice to the New York Stock Exchange or any applicable self-regulatory organization or to holders of the Notes of the record or payment date of the related interest payment.
Sinking Fund Requirement
The Notes do not have the benefit of any sinking fund and are not subject to redemption at the option of the holder.
Limitation on Consolidation, Merger and Sales
Under the terms of the indenture or the Notes, nothing shall prevent any consolidation or merger of CMS Energy with or into any other person or persons (whether or not affiliated with CMS Energy), or successive consolidations or mergers in which CMS Energy or its successor or successors shall be a party or parties, or shall prevent any conveyance, transfer or lease of the property of CMS Energy as an entirety or substantially as an entirety, to any other person (whether or not affiliated with CMS Energy); provided, however, that:
•in case CMS Energy shall consolidate with or merge into another person or convey, transfer or lease its properties and assets as an entirety or substantially as an entirety to any person, the entity formed by such consolidation or into which CMS Energy is merged or the person that acquires by conveyance or transfer, or that leases, the properties and assets of CMS Energy as an entirety or substantially as an entirety shall be a corporation or a limited liability company organized and existing under the laws of the United States of America, any state thereof or the District of Columbia and shall expressly assume, by an indenture (or indentures, if at such time there is more than one trustee) supplemental to the indenture, executed by the successor person and delivered to the trustee, in form satisfactory to the trustee, the due and punctual payment of the principal of and any premium and interest on the Notes and the performance of every obligation in the indenture and the Notes on the part of CMS Energy to be performed or observed;
•immediately after giving effect to such transaction, no event of default or event that, after notice or lapse of time, or both, would become an event of default, shall have occurred and be continuing; and

27

•either CMS Energy or the successor person shall have delivered to the trustee an officers’ certificate and an opinion of counsel, each stating that such consolidation, merger, conveyance, transfer or lease and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture complies with the provisions of the indenture and all conditions precedent therein relating to such transaction.
Upon any consolidation by CMS Energy with or merger of CMS Energy into any other person or any conveyance, transfer or lease of the properties and assets of CMS Energy substantially as an entirety to any person as described above, the successor person formed by such consolidation or into which CMS Energy is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, CMS Energy under the indenture with the same effect as if such successor person had been named as CMS Energy therein; and thereafter, except in the case of a lease, the predecessor person shall be released from all obligations and covenants under the indenture and the Notes.
Events of Default
The occurrence of any of the following events with respect to the Notes will constitute an “event of default” with respect to the Notes:
◦default in the payment of any interest on any of the Notes when it becomes due and payable, and continuance of such default for a period of 30 days (except for the deferral of interest payments as discussed above in “Deferral of Interest Payments”);
◦default in the payment when due and payable of any of the principal of or the premium, if any, on any of the Notes; or
◦certain events of bankruptcy, insolvency or reorganization relating to CMS Energy.
With respect to the Notes, a failure to comply with other covenants under the indenture does not constitute an event of default.
If any event of default on the Notes shall have occurred and be continuing, either the trustee or the holders of not less than 25% in aggregate principal amount of the Notes then outstanding may declare the principal of all of the Notes and the premium, if any, thereon and interest, if any, accrued thereon to be due and payable immediately. 
The indenture provides that the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request, order or direction of the holders of the Notes, unless such holders shall have offered to the trustee reasonable indemnity. Subject to such provisions for indemnity and certain other limitations contained in the indenture, the holders of a majority in aggregate principal amount of the securities issued under the indenture of each affected series then outstanding (voting as one class) will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or 

28

exercising any trust or power conferred on the trustee, with respect to the securities of such affected series.
After a declaration of acceleration, but before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in aggregate principal amount of the outstanding Notes, by written notice to us and the trustee, may rescind and annul such declaration if:
•we have paid (or deposited with the trustee a sum sufficient to pay): (i) all overdue interest on all Notes; (ii) the principal amount of any Notes that have become due otherwise than by such declaration of acceleration; (iii) to the extent that payment of such interest is lawful, interest upon overdue interest; and (iv) all sums paid or advanced by the trustee under the indenture and the reasonable compensation, expenses, disbursements and advances of the trustee, its agents and counsel; and
•all events of default, other than the non-payment of the principal amount and any accrued and unpaid interest that have become due by such declaration of acceleration, have been cured or waived.
The indenture provides that no holders of Notes may institute any action against CMS Energy under the indenture (except actions for payment of overdue principal, premium or interest) unless such holder previously shall have given to the trustee written notice of default and continuance thereof and unless the holders of not less than 25% in aggregate principal amount of securities issued under the indenture of each affected series then outstanding (voting as one class) shall have requested the trustee to institute such action and shall have offered the trustee reasonable indemnity against costs, expenses and liabilities, the trustee shall not have instituted such action within 60 days of such request and the trustee shall not have received direction inconsistent with such request by the holders of a majority in aggregate principal amount of the securities of each affected series then outstanding (voting as one class).
The indenture requires CMS Energy to furnish to the trustee annually a statement as to CMS Energy’s compliance with all conditions and covenants under the indenture. The indenture provides that the trustee may withhold notice to the holders of the Notes of any default affecting such Notes (except defaults as to payment of principal of, or premium or interest on, the Notes) if it considers such withholding to be in the interests of the holders of the Notes.
Modification and Waiver
CMS Energy and the trustee may enter into supplemental indentures without the consent of the holders of the Notes to:
•establish the form and terms of any series of securities under the indenture;
•secure the Notes;

29

•provide for the assumption of our obligations to the holders of the Notes in the event of a merger or consolidation, or conveyance, transfer or lease of our property substantially as an entirety;
•surrender any right or power conferred upon us;
•add to our covenants (and related events of default) for the benefit of the holders of the Notes;
•correct any mistake, cure any ambiguity or correct or supplement any inconsistent or otherwise defective provision contained in the indenture (including any supplemental indenture); provided, that such modification or amendment does not adversely affect the interests of the holders of the Notes in any material respect; provided, further, that any amendment made solely to conform the provisions of the indenture to the description of the Notes contained in this prospectus supplement will not be deemed to adversely affect the interests of the holders of the Notes;
•make any provision with respect to matters or questions arising under the indenture that we may deem necessary or desirable and that shall not be inconsistent with provisions of the indenture; provided, that such change or modification does not, in the good faith opinion of CMS Energy, adversely affect the interests of the holders of the Notes in any material respect;
•comply with the requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act of 1939, as amended;
•add guarantees of obligations under the Notes;
•provide for a successor trustee;
•modify, amend or replace, in whole or in part, the subordination provisions of the indenture in connection with the creation and issuance of any junior subordinated notes of any series (but not with respect to any outstanding junior subordinated notes expressly made subject to the subordination provisions of the indenture);
•add any additional events of default with respect to all or any series of securities under the indenture;
•change or eliminate any other provisions of the indenture to such extent as shall be necessary or desirable to permit or facilitate the issuance, legending, registration, transfer or exchange, redemption or repurchase of securities under the indenture in the form of global securities, including to comply with the rules, practices and procedures of DTC (and related procedures);
•change or eliminate any of the provisions of the indenture, provided that any such change or elimination shall become effective only when there is no security outstanding under the indenture of any series created prior to the execution of the 

30

supplemental indenture effecting such change or elimination which is entitled to the benefit of such provision (or such change or elimination only applies to a new series of securities being established or created); and
•provide for or confirm the issuance of additional securities of any series in accordance with the terms of the indenture.
CMS Energy and the trustee, with the consent of the holders of a majority in total principal amount of securities issued under the indenture of all series, including the Notes, then outstanding and affected (voting as one class), may change in any manner the provisions of the indenture or modify in any manner the rights of the holders of the securities of each such affected series. CMS Energy and the trustee may not, without the consent of the holders of each Note affected, enter into any supplemental indenture to: 
•change the time of payment of the principal;
•reduce the principal amount of such Note;
•reduce the rate or change the time of payment of interest on such Note;
•impair the right to institute suit for the enforcement of any payment on any Note when due;
•change the currency in which any Note is payable;
•reduce the amount payable on the redemption of the Notes; or
•subject to specified exceptions, modify certain provisions of the indenture relating to modification of the indenture or waiver under the indenture.
In addition, no such modification may reduce the percentage in principal amount of the securities of the affected series, the consent of whose holders is required for any such modification or for any waiver provided for in the indenture. 
Prior to the acceleration of the maturity of any security, the holders, voting as one class, of a majority in total principal amount of the securities issued under the indenture with respect to which a default or event of default shall have occurred and be continuing may on behalf of the holders of all such affected securities waive any past default or event of default and its consequences, except: 
•our failure to pay principal of or interest on any securities issued under the indenture when due; or
•a default or an event of default in respect of a covenant or provision of the indenture or of any security that cannot be modified or amended without the consent of the holders of each security affected.

31

Discharge of the Indenture
The indenture provides that, at the option of CMS Energy, CMS Energy will be discharged from all obligations under the indenture and the indenture shall cease to be of further effect (except for certain obligations, including to register the transfer of or exchange the Notes, to replace stolen, lost or mutilated Notes, to maintain paying agencies and to maintain the trust described below) if:
aall the Notes that have not been paid in full and delivered to the trustee for cancellation shall have become due and payable, or by their terms become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the trustee;

cCMS Energy has paid all other sums payable under the indenture; and
dthe trustee receives an officers’ certificate and opinion of counsel stating that all conditions precedent in the indenture relating to the satisfaction and discharge of the indenture have been complied with.

(c)    The Committee, no later than March 1st of the calendar year following the Performance Year, will review for approval proposed Annual Awards for the total of all CMSICP Officer participants, as recommended by the President and CEO of CMS Energy.  All proposed Annual Awards shall be approved by the Committee.  Before the payment of any Annual Awards, the Company’s outside auditors and the Committee will certify in writing that the established Performance Goals were in fact satisfied.

(d)    The Committee reserves the right to modify the established Performance Goals with respect to unforeseeable circumstances or otherwise exercise discretion with respect to proposed Annual Awards as it deems necessary to maintain the spirit and intent of the CMSICP, provided that if such  discretion increases the Annual Award it does not exceed the computed performance factor by more than 20%.  The Committee also reserves the right in its discretion to not pay Annual Awards for a Performance Year.  All decisions of the Committee are final.

II.    CORPORATE PERFORMANCE GOALS

2.1    In General.  Each year, the Committee uses Performance Goals to determine the Annual Award measures.  A table shall be created by the Compensation Committee for the current year Performance Goals. 

2.2    Plan Performance Factor.  The plan performance factor used to calculate an Annual Award is based on the results of the corporate established Performance Goals and is capped at two times the standard award amount.  The Plan Performance Factor is established in a table relating specific performance results to specific plan Performance Goals. This table shall be created by the Committee for each Performance Year.

III.    ANNUAL AWARD FORMULA

3.1    Annual Awards.  Annual Awards for each eligible Officer will be based upon a percentage of the Officer’s Base Salary for the Performance Year times the Plan performance factor for the year as determined under 2.2 above.  The standard award percentage for each eligible Officer will be approved annually by the Committee for each Performance Year.  The total amount of a CMSICP participant Officer’s Annual Award shall be computed according to the annual award formula set forth in Section 3.2.  An Officer’s standard award amount is equal to the Officer’s Annual Award computed using a plan performance factor of 100%.

3.2    Calculation of Award.  Annual Awards for Officer CMSICP participants will be calculated and made as follows:

4

Annual Award = Base Salary times
Standard Award Percentage times Plan Performance Factor

IV.    PAYMENT OF ANNUAL AWARDS

4.1    Cash Annual Award.  All Annual Awards for a Performance Year will be paid in cash after certification by the outside auditors of the Company and the Committee that the established Performance Goals have been satisfied, but not later than March 15th of the calendar year following the Performance Year provided that the Annual Award for a particular Performance Year has not been deferred voluntarily pursuant to Section 4.2. The amounts required by law to be withheld for income and employment taxes will be deducted from the Annual Award payments.  All Annual Awards become the obligation of the company on whose payroll the Officer is enrolled at the time the Committee makes the Annual Award.

4.2    Deferred Annual Awards.

(a)    The payment of all or any portion (rounded to an even multiple of 10%) of a cash Annual Award may be deferred voluntarily at the election of an individual Plan participant in salary grades E-1 – E-9.  Any such deferral will be net of any applicable FICA or FUTA taxes.  A separate irrevocable election must be made prior to the Performance Year.  Any Annual Award made by the Committee after termination of employment of a participant or retirement of a participant will be paid in accordance with any deferral election made within the enrollment period.

(b)    At the time the participant makes a deferral election he or she must select the payment options (including the Payment Event as set forth at (c) below and the Payment Term as set forth at (d) below) applicable to the Deferred Annual Award for the Performance Year, as well as any earnings or income attributable to such amounts.  The payment options elected will apply only to that year’s Deferred Annual Award and will not apply to any previous Deferred Annual Award or to any subsequent Deferred Annual Award.  Any participant who elects to defer all or a portion of an Annual Award and who fails to select a Payment Event or a Payment Term will be presumed to have elected a Payment Event of Separation from Service in accordance with paragraph (c)(i) below and/or a Payment Term of a single sum.

5

(c)    The Payment Event elected can be either:

(i)    Separation from Service for any reason other than death.  Payment will be made, or begin, in the later of: (1) January of the year following the year of the Separation from Service; or (2) the seventh month after the month of the Separation from Service.  Later installments, if any, will be paid in January of the succeeding years. Effective for amounts deferred in 2019 and succeeding years, payment will be made, or begin, in the seventh month after the month of Separation from Service.  Later installments, if any, will be paid in the same month of the succeeding years;

(ii)    Payment upon attainment of a date certain that is more than 1 year after the last day of the applicable Performance Year.  Later installments, if any, will be paid in the same month of the succeeding years; or

(iii)    The later of (i) or (ii) above.

(d)    Payment Term.  At the time of electing to defer an Annual Award, the participant must also elect how he or she wishes to receive any such payment from among the following options (the participant may elect a separate Payment Term for each Payment Event elected):

(i)    Payment in a single sum upon occurrence of the Payment Event.

(ii)    Payment of a series of annual installment payments over a period from two (2) years to fifteen (15) years following the Payment Event.  Each installment payment shall be equal to a fractional amount of the balance in the account the numerator of which is one and the denominator of which is the number of installment payments remaining.  Although initially such installment payments will be identical, actual payments may vary based upon investment performance.  For example, a series of 5 installment payments will result in a payout of 1/5 of the account balance in the first installment, 1/4 of the account balance (including investment gains or losses since the first installment date) in the second installment, etc.

(e)    Changes to Payment Options.  Once a payment option has been elected, subsequent changes which would accelerate the receipt of benefits from the Plan are not permitted, except that the Plan Administrator may at its discretion accelerate payments to the extent permitted by Code Section 409A and applicable regulations.  A subsequent election to change the payment options related to a Payment Event, in order to delay a payment or to change the form of a payment, can only be made when all of the following conditions are satisfied:

6

(i)    such election may not take effect until at least 12 months after the date on which the election is made;

(ii)    (ii)    the payment(s) with respect to which such election is made is deferred for a period of not less than 5 years from the date such payment would otherwise have been made (or, in the case of installment payments under Section 4.2(d)(ii) with regard to amounts deferred (and the related earnings) prior to January 1, 2016, 5 years from the date the first installment was scheduled to be paid); and

(iii)    such election must be made not less than 12 months before the date the payment was previously scheduled to be made (or, in the case of installment payments under Section 4.2(d)(ii) with regard to amounts deferred (and the related earnings) prior to January 1, 2016, 12 months before the first installment was scheduled to be paid), if the participant’s previous commencement date was a specified date.

Effective January 1, 2016, the right to a series of installment payments is to be treated as a right to a series of separate payments to the extent permissible under Code Section 409A and any applicable regulations. When making a subsequent election with respect to the payment of any post-December 31, 2015 deferral, the participant may make a separate election with respect to each separate payment, provided that such election must result in all of the applicable Performance Year’s deferral with related earnings being paid in a single sum or in a series of annual payments over a period from two (2) to fifteen (15) consecutive years.

(f)    Investments. At the time of electing to voluntarily defer payment, the participant must elect how the Deferred Annual Award will be treated by the Company or Consumers Energy.  To the extent that any amounts deferred are placed in a rabbi trust with an independent Record Keeper, a participant who has previously deferred amounts under this Plan will automatically have his or her existing investment profile apply to this deferral also.  All determinations of the available investment options by the Plan Administrator are final and binding upon participants.  A participant may change the investment elections at any time prior to the payment of the benefit, subject to any restrictions imposed by the Plan Administrator, the plan Record Keeper or by any applicable laws and regulations.  A participant not making an election will have amounts deferred treated as if in a Lifestyle Fund under the Savings Plan for Employees of Consumers Energy and other CMS Energy Companies (the “Savings Plan”) applicable to the participant’s age 65, rounded up, or such other investment as determined by the Benefit Administration Committee.  All gains and losses will be based upon the performance of the investments selected by the participant from the date the deferral is first credited to the nominal account.  If the Company elects to fund its obligation as discussed below, then investment performance will be based on the balance as determined by the Record Keeper.
7

(g)    The amount of any Deferred Annual Award is to be satisfied from the general corporate funds of the company on whose payroll the Plan participant was enrolled prior to the payout beginning and are subject to the claims of general creditors.  This is an unfunded nonqualified deferred compensation plan.  To the extent the Company or Consumers Energy, as applicable, elects to place funds with a trustee to pay its future obligations under this Plan, such amounts are placed for the convenience of the Company or Consumers Energy, remain the property of the Company or Consumers Energy and the participant shall have no right to such funds until properly paid in accordance with the provisions of this Plan.  For administrative ease and convenience, such amounts may be referred to as participant accounts, but as such are a notional account only and are not the property of the participant.  Such amounts remain subject to the claims of the creditors of the Company or Consumers Energy.

(h)    Payment in the Event of an Unforeseeable Emergency. The participant may request that payments commence immediately upon the occurrence of an unforeseeable emergency as that term is defined in Code Section 409A and any applicable regulations.  Generally, an unforeseeable emergency is a severe financial hardship resulting from an illness or accident of the participant or the participant’s spouse or dependent, loss of the participant’s property due to casualty, or other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the control of the participant.  A distribution on account of unforeseeable emergency may not be made to the extent that such emergency is or may be relieved through reimbursement or compensation from insurance or otherwise, by liquidation of the participant’s assets (without causing severe financial hardship), or by cessation of deferrals under this arrangement, the Savings Plan or other arrangements. Distributions because of an unforeseeable emergency shall not exceed the amount permitted under Section 409A and accordingly are limited to the amount reasonably necessary to satisfy the emergency need (after use of insurance proceeds, liquidation of assets, etc.) plus an amount to pay taxes reasonably anticipated as a result of the distribution. In the event any payment is made due to an unforeseeable emergency, all deferral elections for the current Performance Year will cease and the participant will not be eligible to make any deferral elections under this Plan for the following Performance Year.  For any participant receiving a hardship withdrawal under the Savings Plan, all deferral elections under this Plan for the current Performance Year will cease and the participant will not be eligible to make any deferral elections under this Plan for the following Performance Year.

8

4.3    Payment in the Event of Death.

(a)    A participant may name the beneficiary of his or her choice on a beneficiary form provided by the Company or Record Keeper, and the beneficiary shall receive, within 90 days of the participant’s death, in a single sum, all payments credited to the participant in the event that the participant dies prior to receipt of Deferred Annual Awards.  If there is no beneficiary named at the time of participant’s death or if the beneficiary does not survive the participant, the payment will be made to the participant’s estate. In no event may any recipient designate a year of payment for an amount payable upon the death of the participant.

(b)    A participant may change beneficiaries at any time, and the change will be effective as of the date the plan Record Keeper or Company accepts the form as complete.  Neither the Company nor Consumers Energy will be liable for any payments made before receipt and acceptance of a written beneficiary request.

V.    CHANGE OF STATUS

Payments in the event of a change in status will not be made if no Annual Awards are made for the Performance Year.

5.1    Pro-Rata Annual Awards.  A new Officer participant, whether hired or promoted to the position, or an Officer promoted to a higher salary grade during the Performance Year will receive a pro rata Annual Award based on the percentage of the Performance Year in which the Officer is in a particular salary grade.  An Officer participant whose salary grade has been lowered, but whose employment is not terminated during the Performance Year will receive a pro rata Annual Award based on the percentage of the Performance Year in which the Officer is in a particular salary grade.

5.2    Termination.  An Officer participant whose employment is terminated pursuant to a violation of the Company code of conduct or other corporate policies will not be considered for or receive an Annual Award.

5.3    Resignation.  An Officer participant who resigns prior to payment (during or after a Performance Year) will not be eligible for an Annual Award.  If the resignation is due to reasons such as a downsizing or reorganization, or the ill health of the Officer or ill health in the immediate family, the Officer may petition the Plan Administrator and may be considered, in the discretion of the Plan Administrator, for a pro rata Annual Award.  The Plan Administrator’s decision to approve or deny the request for a pro rata Annual Award shall be final.

5.4    Death, Disability, Retirement, Leave of Absence.  An Officer participant whose status as an active employee is changed during the Performance Year due to death, 
9

Disability, Retirement, or Leave of Absence will receive a pro rata Annual Award.  An Officer participant whose employment is terminated following the Performance Year but prior to payment due to death, Disability or Retirement will continue to be eligible for an Annual Award for the Performance Year.  Any such payment or Annual Award payable due to the death of the Officer participant will be made to the named beneficiary, or if no beneficiary is named or if the beneficiary doesn’t survive the Officer participant, then to the Officer participant’s estate no later than March 15 following the applicable Performance Year.  Notwithstanding the above, an Officer participant who retires, is on Disability or Leave of Absence and who becomes employed by a competitor of CMS Energy or Consumers Energy or their subsidiaries or affiliates prior to award payout will forfeit all rights to an Annual Award, unless prior approval of such employment has been granted by the Committee.  A “competitor” shall mean an entity engaged in the business of (1) selling (a) electric power or natural gas at retail or wholesale within the State of Michigan or (b) electric power at wholesale within the market area in which an electric generating plant owned by a subsidiary or affiliate of CMS Energy is located or (2) developing an electric generating plant within the State of Michigan or a market area in which an electric generating plant owned by a subsidiary or affiliate of CMS Energy is located.

5.5    Clawback.

(a)    If, due to a restatement of CMS Energy’s or an affiliate’s publicly disclosed financial statements or otherwise, an Officer is subject to an obligation to make a repayment or return of benefits to CMS Energy or an affiliate pursuant to a clawback provision contained in this Plan, a supplemental executive retirement plan, the Performance Incentive Stock Plan, or any other benefit plan (a “benefit plan clawback provision”) of the Company, the Committee may determine that it shall be a precondition to the payment of any award under this Plan, that the Officer fully repay or return to the Company any amounts owing under such benefit plan clawback provision (taking into account the requirements of Code Section 409A, to extent applicable).  Any and all awards under this Plan are further subject to any provision of law, which may require the Officer to forfeit or return any benefits provided hereunder, in the event of a restatement of the Company’s publicly disclosed accounting statements or other illegal act, whether required by Section 304 of the Sarbanes-Oxley Act of 2002, Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, federal securities law (including any rule or regulation promulgated by the Securities and Exchange Commission), any state law, or any rule or regulation promulgated by the applicable listing exchange or system on which the Company lists its traded shares.

(b)    To the degree any benefits hereunder are not otherwise forfeitable pursuant to the preceding sentences of this Section 5.5, the Board or a Committee delegated authority by the Board (“delegated Committee”), may require the Officer to return to the Company or forfeit any amounts granted under this Plan, if:
10

1.    the grant of such compensation was predicated upon achieving certain financial results which were subsequently the subject of a substantial accounting restatement of the Company’s financial statements filed under the securities laws (a “financial restatement”),

2.    a lower payout or Annual Award (“reduced financial results”), would have occurred based upon the financial restatement, and

3.    in the reasonable opinion of the Board or the delegated Committee, the circumstances of the financial restatement justify such a modification of the Annual Award.  Such circumstances may include, but are not limited to, whether the financial restatement was caused by misconduct, whether the financial restatement affected more than one period and the reduced financial results in one period were offset by increased financial results in another period, the timing of the financial restatement or any required repayment, and other relevant factors.

Unless otherwise required by law, the provisions of this Subsection (b) relating to the return of previously paid Plan benefits shall not apply unless a claim is made therefore by the Company within three years of the payment of such benefits.

(c)    The Board or delegated Committee shall also have the discretion to require a clawback in the event of a mistake or accounting error in the calculation of a benefit or an award that results in a benefit to an eligible individual to which he/she was not otherwise entitled.  The rights set forth in this Plan concerning the right of the Company to a clawback are in addition to any other rights to recovery or damages available at law or equity and are not a limitation of such rights.

VI.    MISCELLANEOUS

6.1    Impact on Benefit Plans.  Payments made under the Plan will be considered as earnings for the Supplemental Executive Retirement Plans but not for purposes of the Employees’ Savings Plan, Pension Plan, or other Officer benefit programs.

6.2    Impact on Employment.  Neither the adoption of the Plan nor the granting of any Annual Award under the Plan will be deemed to create any right in any individual to be retained or continued in the employment of the Company or any corporation within the Company’s control group.

6.3    Termination or Amendment of the Plan.  The Board of Directors of CMS Energy may amend or terminate the Plan at any time.  Upon termination, any Deferred Annual Award accrued under the Plan will remain in the Plan and be paid out in accordance with the payment options previously selected.  The Plan Administrator 
11

is authorized to make any amendments that are deemed necessary or desirable to comply with any applicable laws, regulations or orders or as may be advised by counsel or to clarify the terms and operation of the Plan.  The Company may terminate the Plan and accelerate payment of any deferred benefits under the Plan if it acts consistent in all respects with the requirements of Code Section 409A and any applicable regulations with respect to when a terminated plan may accelerate payment to a participant.

6.4    Governing Law.  The Plan will be governed and construed in accordance with the laws of the State of Michigan.

6.5    Dispute Resolution.  Any disputes related to the Plan must be brought to the Plan Administrator.  The Plan Administrator is granted full discretionary authority to apply the terms of the Plan, make administrative rulings, interpret the Plan and make any other determinations with respect to the Plan.  If the Plan Administrator makes an adverse determination and the participant disagrees with or wishes to appeal the determination, the participant must appeal the decision to the Plan Administrator, in writing and not later than 60 days from when the determination was mailed to the participant.  If the participant does not timely appeal the original determination, the participant has no further rights under the Plan with respect to the matter presented in the claim.  If the participant appeals the original determination and that appeal does not result in a mutually agreeable resolution, then the dispute shall be subject to final and binding arbitration before a single arbitrator selected by the parties to be conducted in Jackson, Michigan, provided the participant makes such request for arbitration in writing within 30 days of the final decision by the Plan Administrator. The arbitration will be conducted and finished within 90 days of the selection of the arbitrator.  The parties shall share equally the cost of the arbitrator and of conducting the arbitration proceeding, but each party shall bear the cost of its own legal counsel and experts and other out-of-pocket expenditures.  The arbitrator must use an arbitrary and capricious standard of review when considering any determinations and findings by the Plan Administrator.

VII.    AMENDMENT TO REFLECT CODE SECTION 409A

7.1    Code Section 409A.  This Plan has been amended, effective as of January 1, 2005, to comply with the requirements of Code Section 409A.  To the extent counsel determines additional amendments may be reasonable or desirable in order to comply with Code Section 409A, and any other applicable rules, laws and regulations, such changes shall be authorized with the approval of the Plan Administrator.
