Pursuant to Section 151 of the 
 General Corporation Law of the State of Delaware 
  

 
 The undersigned,
pursuant to the provisions of Section 151 of the General Corporation Law of the State of Delaware (the “DGCL”), does hereby certify that, pursuant to the authority expressly vested in the Board of Directors of NCI Building
Systems, Inc., a Delaware corporation (the “Corporation”), by the Certificate of Incorporation, the Board of Directors has by resolution duly provided for the issuance of and created a series of Preferred Stock of the Corporation,
par value $1.00 per share (the “Preferred Stock”), and in order to fix the designation and amount and the voting powers, preferences and relative, participating, optional and other special rights, and the qualifications, limitations
and restrictions, of a series of Preferred Stock, has duly adopted resolutions setting forth such rights, powers and preferences, and the qualifications, limitations and restrictions thereof, of a series of Preferred Stock as set forth in this
Certificate of Designations, Preferences and Rights of Series B Cumulative Convertible Participating Preferred Stock (the “Certificate”). 
 Each share of such series of Preferred Stock shall rank equally in all respects and shall be subject to the following provisions: 
 Section 1. Number of Shares and Designation. 400,000 shares of Preferred Stock of the Corporation shall constitute a series of Preferred Stock designated as Series B Cumulative Convertible
Participating Preferred Stock (the “Series B Preferred Stock”). Subject to and in accordance with the provisions of Section 11(b), the number of shares of Series B Preferred Stock may be increased (to the extent of the
Corporation’s authorized and unissued Preferred Stock) or decreased (but not below the number of shares of Series B Preferred Stock then outstanding) by further resolution duly adopted by the Board of Directors and the filing of a certificate
of increase or decrease, as the case may be, with the Secretary of State of the State of Delaware. 
 Section 2. Rank.
The Series B Preferred Stock shall, with respect to payment of dividends, redemption payments, rights (including as to the distribution of assets) upon liquidation, dissolution or winding up of the affairs of the Corporation, or
otherwise (i) rank senior and prior to the Corporation’s common stock, par value $0.01 per share (the “Common Stock”) and each other class or series of equity securities of the Corporation, whether currently issued
or issued in the future, that by its terms ranks junior to the Series B Preferred Stock as to payment of dividends, redemption payments, rights (including as to the distribution of assets) upon liquidation, dissolution or winding up of the affairs
of the Corporation, or otherwise (all of such equity securities, including the Common Stock, are collectively referred to herein as the “Junior  

 
Securities”) and (ii) rank junior to each class or series of equity securities of the Corporation, whether currently issued or issued in the future without violation of
this Certificate, that by its terms ranks senior to the Series B Preferred Stock as to payment of dividends, redemption payments, rights (including as to the distribution of assets) upon liquidation, dissolution or winding up of the affairs of the
Corporation, or otherwise (all of such equity securities are collectively referred to herein as the “Senior Securities”). The respective definitions of Junior Securities and Senior Securities shall also include any securities,
rights or options exercisable or exchangeable for or convertible into any of the Junior Securities or Senior Securities, as the case may be. At the time of the initial issuance of the Series B Preferred Stock there shall be no Senior Securities
outstanding. For the avoidance of doubt, at the time of the initial issuance of the Series B Preferred Stock or at any time in the future during which shares of Series B Preferred Stock are outstanding, there shall be no other class or series of
equity securities of the Corporation that ranks on parity with the Series B Preferred Stock as to payment of dividends, redemption payments or rights (including as to the distribution of assets) upon liquidation, dissolution or winding up of the
affairs of the Corporation. Each other class or series of equity securities of the Corporation issued at any time during which shares of Series B Preferred Stock are outstanding shall, subject to and in accordance with the provisions of
Section 11, expressly by its terms rank junior or senior to the Series B Preferred Stock as to payment of dividends, redemption payments or rights (including as to the distribution of assets) upon liquidation, dissolution or winding up

available for the payment of dividends, dividends on the terms described below: 
 (i) Holders of shares of Series B Preferred
Stock shall be entitled to participate equally and ratably with the holders of shares of Common Stock in all cash dividends paid on the shares of Common Stock as if immediately prior to each Common Stock Dividend Record Date (as defined below), all
shares of Series B Preferred Stock then outstanding were converted into shares of Common Stock (assuming that all of the then issued and outstanding shares of Series B Preferred Stock could be converted into shares of Common Stock on the record date
in respect of such dividend). Dividends or distributions payable pursuant to this Section 4(a)(i) (the “Participating Dividends”) shall be payable on the same date that such dividends or distributions are payable to
holders of shares of Common Stock (a “Common Stock Dividend Payment Date”), and no dividends shall be payable to holders of shares of Common Stock unless the full dividends contemplated by this Section 4(a)(i) are paid
at the same time to the Holders of the Series B Preferred Stock. Other than in respect of dividends paid in cash on the shares of Common Stock as and to the extent provided for in this paragraph (i), Holders of shares of Series B Preferred Stock
shall not be entitled to participate in dividends or distributions of any nature paid on or in respect of the Common Stock or to holders thereof. 

  
 12 

 (ii) In addition to any dividends pursuant to Section 4(a)(i), the Corporation
shall pay, if, as and when declared by the Board of Directors, out of funds legally available therefor, on each Series B Preferred Dividend Payment Date dividends on each outstanding share of Series B Preferred Stock (the “Series B Preferred
Dividends”) at a rate per annum equal to the Dividend Rate as further specified below. Series B Preferred Dividends on each share of Series B Preferred Stock shall accrue and accumulate on a daily basis from the Issuance Date of such
share, whether or not declared and whether or not the Corporation has funds legally available for the payment of such dividends, shall compound quarterly on each Series B Preferred Dividend Payment Date and shall be payable quarterly in arrears, if,
as and when so authorized and declared by the Board of Directors, on each Series B Preferred Dividend Payment Date, commencing on the first Series B Preferred Dividend Payment Date following the Issuance Date of such share. The amount of Series B
Preferred Dividends accruing with respect to any share of Series B Preferred Stock for any day shall be determined by dividing (x) the Implied Quarterly Dividend Amount with respect to such day by (y) the actual number of
days in the Payment Period in which such day falls. The amount of Series B Preferred Dividends payable with respect to any share of Series B Preferred Stock for any Payment Period shall equal the sum of the Series B Preferred Dividends accrued in
accordance with the prior sentence of this Section 4(a)(ii) with respect to such share during such Payment Period. Series B Preferred Dividend payments shall be aggregated per Holder and shall be made to the nearest cent (with $.005
being rounded upward). 
 (iii) Subject to and in accordance with the provisions of Section 4(a)(iv), the Series B
Preferred Dividends may, at the option of the Corporation, be paid in cash or by issuing fully paid and nonassessable shares of Series B Preferred Stock. If the Corporation pays any Series B Preferred Dividend in shares of Series B Preferred Stock,
the number of shares of Series B Preferred Stock to be paid in respect of such Series B Preferred Dividend will be equal to the number of shares (including fractional shares) that have an aggregate Liquidation Preference equal to the amount of such
Series B Preferred Dividend. 
 (iv) Notwithstanding anything to the contrary in this Section 4(a) (including for
the avoidance of doubt, the last sentence of Section 4(a)(v)), the Corporation shall not pay any Series B Preferred Dividends accumulating prior to the date following the first date on which there are no longer any outstanding
Convertible Notes (as defined in the Investment Agreement) by issuing fully paid and nonassessable shares of Series B Preferred Stock, but must pay such Series B Preferred Dividends on any applicable Series B Preferred Dividend Payment Date, if at
all, in cash. 
 (v) Each Participating Dividend or Series B Preferred Dividend shall be paid pro rata to the Holders entitled
thereto. Each Participating Dividend or Series B Preferred Dividend shall be payable to the Holders of Series B Preferred Stock as they appear on the Register at the close of business on the record date designated by the Board of Directors for such
dividends (each such date, a “Dividend Payment Record Date”), which (i) with respect to Participating Dividends, shall be the same day as the record date for the payment of dividends to the holders of shares of Common
Stock (the “Common Stock Dividend Record Date”) and, (ii) with respect to Series B Preferred Dividends, shall be not more than thirty (30) days nor less than ten (10) days preceding the applicable Series B
Preferred Dividend Payment Date. Notwithstanding the forgoing, the Base Amount Accrued Dividends may be declared and paid in cash or in shares of Series B Preferred Stock at any time to Holders of record on the Dividend Payment Record Date therefor.

  
 13 

 (b) Upon the occurrence of a Default, the Dividend Rate shall increase by the Applicable
Default Dividend Rate from and including the date on which the Default shall occur and be continuing through but excluding the date on which all then occurring Defaults are no longer continuing. The Dividend Rate shall not be increased further
pursuant to this Section 4(b) for a subsequent Default occurring while the Dividend Rate is already increased pursuant to this Section 4(b); provided, however, in the event that a Default of the type set forth
in clause (iii) of the definition of “Default” occurs, or is continuing to occur, after June 30, 2011 and the Applicable Default Dividend Rate in effect as of such date is 3.00% per annum, the Dividend Rate shall
increase by an additional 3.00% per annum and shall remain so increased until the date on which such Default set forth in clause (iii) is no longer continuing. 

(c) At any time during which a Default shall be occurring, no dividends shall be declared or paid or set apart for payment, or other
distributions declared or made, upon any Junior Securities, nor shall any Junior Securities be redeemed, purchased or otherwise acquired for any consideration (nor shall any moneys be paid to or made available for a sinking fund for the redemption
of any shares of any such Junior Securities) by the Corporation, directly or indirectly (except, subject to and in accordance with the provisions of Section 11 hereof and Article VI of the Stockholders Agreement, by conversion into or
exchange for Junior Securities or the payment of cash in lieu of fractional shares in connection therewith). 
 (d) From and
after March 15, 2012 (the occurrence of such date, the “Dividend Reduction Event”), the Base Dividend Rate shall irrevocably become 0.00% for all days thereafter. For the avoidance of doubt, the Dividend Rate shall be subject
to increase pursuant to Section 4(b) even if the Base Dividend Rate becomes 0.00% pursuant to this Section 4(d). 
 (e) Neither the Corporation nor any of its Subsidiaries shall (i) declare, pay or set aside for payment any dividends or distributions upon any Junior Securities (except,
(x) subject to and in accordance with the provisions of Section 11 hereof and Article VI of the Stockholders Agreement, for any such dividends or distributions payable solely in Junior Securities or (y) for such
ordinary cash dividends (as may be determined and declared by the Board of Directors from time to time) declared, paid or set aside for payment after the Dividend Reduction Event on shares of Common Stock in which the shares of Series B Preferred
Stock participate pursuant to Section 4(a)(i)) or (ii) repurchase, redeem or otherwise acquire any Junior Securities for any consideration or pay any moneys or make available for a sinking fund for the redemption of any
shares of such Junior Securities (except, subject to and in accordance with the provisions of Section 11 hereof and Article VI of the Stockholders Agreement, by conversion into or exchange for Junior Securities or the payment of cash in
lieu of fractional shares in connection therewith and any consideration consisting solely of Junior Securities), unless, in each case, the Corporation has access to sufficient lawful funds immediately following such action such that the Corporation
would be legally permitted to redeem in full all shares of the Series B Preferred Stock then outstanding for an amount equal to the sum of (A) the aggregate Liquidation Preference and (B) the aggregate Accrued Dividends of
such shares as of such date. 
 (f)

 Section 5. Liquidation Rights. 

(a) In the event of any Liquidation, each Holder shall be entitled to receive liquidating distributions out of the assets of the
Corporation legally available for distribution to its stockholders, before any payment or distribution of any assets of the Corporation shall be made or set apart for holders of any Junior Securities, including, without limitation, the Common Stock,
for such Holder’s shares of Series B Preferred Stock in an amount equal to the greater of (i) the sum of (A) the aggregate Liquidation Preference and (B) the aggregate Accrued Dividends of such shares as of
the date of the Liquidation and (ii) the amount such Holder would have received had such Holder, immediately prior to such Liquidation, converted such shares of Series B Preferred Stock into shares of Common Stock (pursuant to
Section 6 without regard to any of the limitations on convertibility contained therein). 
 (b) In the event the
assets of the Corporation available for distribution to stockholders upon a Liquidation, shall be insufficient to pay in full the amounts payable with respect to all outstanding shares of the Series B Preferred Stock pursuant to
Section 5(a), such assets, or the proceeds thereof, shall be distributed among the Holders ratably in proportion to the full respective liquidating distributions to which they would otherwise be respectively entitled upon such
Liquidation. 
 (c) Neither the sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all of the assets or business of the Corporation (other than in connection with the liquidation, dissolution or winding up of its business) nor the merger or consolidation of the Corporation into or with any
other Person shall by itself be deemed to be a Liquidation for purposes of this Section 5. 
 Section 6.
Conversion. 
 (a) Conversion Right. 

(i) Subject to and in accordance with the provisions of this Section 6, each Holder of shares of Series B Preferred Stock
shall have the right (the “Conversion Right”), at any time and from time to time, at such Holder’s option, to convert all or any portion of such Holder’s shares of Series B Preferred Stock into fully paid and
non-assessable shares of Common Stock or such other shares of capital stock of the Corporation identical in all material respects to the Common Stock (except that the Corporation shall be required to (1) pay a dividend or distribution on such
capital stock whenever and to such an extent that a dividend or distribution is paid on the Common Stock and (2) pay a dividend or distribution on the Common Stock whenever and to such an extent that a dividend or distribution is paid on such
capital stock) as shall have been approved or consented to, in addition to any vote required by law, by the holders of a majority of the then issued and outstanding shares of Series B Preferred Stock (“Other Capital Stock,” and for
purposes of this Section 6 (and otherwise throughout this Certificate where such inclusion is appropriate by the context) Common Stock and Other Capital Stock shall be collectively referred to as “Common Stock”);
provided, that the Conversion Right shall be exercisable only to the extent that there is a sufficient number of authorized and unissued (or issued and included in treasury) and otherwise unreserved shares of Common Stock into which such
shares of Series B Preferred Stock sought to be converted may convert. Upon a Holder’s election to exercise the 

  
 15 

 
Conversion Right, each share of Series B Preferred Stock for which the Conversion Right is exercised shall be converted into such number of shares of Common Stock (calculated as to each
conversion to the nearest 1/10,000th of a share) equal to the quotient of (A) the sum of (1) the Liquidation Preference and (2) the Accrued Dividends of such share as of the Conversion Date, divided by
(B) the Conversion Price of such share in effect at the time of conversion. 
 (ii) No fractional shares of Common
Stock shall be issued upon the conversion of any shares of Series B Preferred Stock. If more than one share of Series B Preferred Stock shall be surrendered for conversion at one time by the same Holder, the number of full shares of Common Stock
issuable upon conversion thereof shall be computed on the basis of the sum of (A) the aggregate Liquidation Preference and (B) the aggregate Accrued Dividends as of the Conversion Date, on all shares of Series B Preferred
Stock so surrendered. If the conversion of any share or shares of Series B Preferred Stock results in a fractional share of Common Stock issuable after application of the immediately preceding sentence, as applicable, the Corporation shall pay a
cash amount in lieu of issuing such fractional share in an amount equal to such fractional interest multiplied by the Closing Price on the Trading Day immediately prior to the Conversion Date. 

(iii) The Corporation will (to the extent and for so long as the shares of Series B Preferred Stock is convertible) at all times reserve
and keep available out of its authorized and unissued Common Stock, solely for the purpose of effecting conversions of the Series B Preferred Stock into shares of Common Stock, a number of shares of Common Stock equal to 110% of the number of shares
of Common Stock issuable upon conversion of all outstanding shares of Series B Preferred Stock. The Corporation shall take all action permitted by law, including calling meetings of stockholders of the Corporation and soliciting proxies for any
necessary vote of the stockholders of the Corporation, to amend the Certificate of Incorporation to increase the number of authorized and unissued shares of Common Stock (or to otherwise comply with the provisions of Section 6.2 of the
Stockholders Agreement) if at any time there shall be insufficient authorized and unissued shares of Common Stock to permit such reservation or to permit the conversion of all outstanding shares of Series B Preferred Stock. The Corporation covenants
that the Series B Preferred Stock and all Common Stock that may be issued upon conversion of Series B Preferred Stock shall upon issuance be duly authorized, fully paid and non-assessable, will not subject the holders thereof to personal liability
and will not be subject to preemptive rights or subscription rights of any other stockholder of the Corporation, other than the subscription rights provided in the Stockholders Agreement. The Corporation further covenants that, if at any time the
Common Stock shall be listed on the New York Stock Exchange or any other securities exchange or quoted on an automated quotation system, the Corporation shall, if permitted by the rules of such national exchange or automated quotation system, at its
sole expense, cause to be authorized for listing or quotation on such exchange or automated quotation system, all Common Stock issuable upon conversion of the Series B Preferred Stock, subject to official notice of issuance. The Corporation will use
its best efforts to ensure that such Common Stock may be issued without violation of any applicable law or regulation or any requirement of such securities exchange or automated quotation system. 

  
 16 

 (b) Mechanics of Conversion. 

(i) The Conversion Right of a Holder of Series B Preferred Stock shall be exercised by the Holder by the surrender to the Corporation of
the certificates representing the shares of Series B Preferred Stock to be converted at any time during usual business hours at the Corporation’s principal place of business or the offices of the Transfer Agent, accompanied by written notice to
the Corporation that the Holder elects to convert all or a portion of the shares of Series B Preferred Stock represented by such certificates (a “Conversion Notice”) and specifying the name or names (with address or addresses) in
which a certificate or certificates for shares of Common Stock are to be issued and (if so required by the Corporation or the Transfer Agent) by a written instrument or instruments of transfer in form reasonably satisfactory to the Corporation or
the Transfer Agent duly executed by the Holder or its legal representative. 
 (ii) As promptly as practicable after the
surrender of the certificate or certificates for the Series B Preferred Stock pursuant to Section 6(b)(i), the receipt of the Conversion Notice, and the payment of required taxes or duties pursuant to Section 12(i), if
applicable, and in no event later than three Trading Days thereafter, the Corporation shall issue and shall deliver or cause to be issued and delivered to such Holder, or to such other Person on such Holder’s written order (A) one
or more certificates representing the number of validly issued, fully paid and non-assessable whole shares of Common Stock to which the Holder of the Series B Preferred Stock being converted, or the Holder’s transferee, shall be entitled,
(B) if less than the full number of shares of Preferred Stock evidenced by the surrendered certificates is being converted, a new certificate or certificates, of like tenor, for the number of shares of Series B Preferred Stock evidenced
by the surrendered certificate or certificates, less the number of shares being converted and (C) cash for any fractional interest in respect of a share of Common Stock arising upon such conversion settled as provided in
Section 6(a)(ii). 
 (iii) The conversion of any share of Series B Preferred Stock shall be deemed to have been made
at the close of business on the date of the later to occur of giving the Conversion Notice and of surrendering the certificate representing the share of Series B Preferred Stock to be converted so that the rights of the Holder thereof as to the
share of Series B Preferred Stock being converted shall cease and the Person entitled to receive shares of Common Stock shall be treated for all purposes as having become the record holder of those shares of Common Stock at that time (the
“Conversion Date”); provided, however, if on the date of the later to occur of giving such Conversion Notice and of surrendering the certificate representing such share of Series B Preferred Stock to be converted there
is a not a sufficient number of authorized and unissued (or issued and included in treasury) and otherwise unreserved shares of Common Stock to convert such share of Series B Preferred Stock into shares of Common Stock, the “Conversion
Date” of such share of Series B Preferred Stock shall be the close of business on the date on which there is a sufficient number of authorized and unissued (or issued and included in treasury) and otherwise unreserved shares of Common Stock
into which such share of Series B Preferred Stock sought to be converted may convert. Until the Conversion Date with respect to any share of Series B Preferred Stock, such share of Series B Preferred Stock will remain outstanding and will be
entitled to all of the powers, designations, preferences and other rights provided herein, including, without limitation, that such share (x) may be redeemed pursuant to Section 7 or Section 8 and, if not so
redeemed, (y) shall (i) accrue and accumulate Series B Preferred Dividends and participate in Participating Dividends pursuant to Section 4 and (ii) entitle the Holder thereof to the voting rights
provided in Section 11; provided, however, any such shares that are redeemed pursuant to Section 7 or Section 8 shall not be entitled to be converted. 

  
 17 

 (c) Corporation’s Obligations to Issue Common Stock. The Corporation’s
obligations to issue and deliver shares of Common Stock upon conversion of Series B Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by any Holder to enforce the same, any
waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by any
Holder or any other Person of any obligation to the Corporation or any violation or alleged violation of law by any Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Corporation
to any Holder in connection with the issuance of such shares of Common Stock. 
 Section 7. Milestone Redemption.

 (a) Milestone Redemption. 
 (i) Each Holder of shares of Series B Preferred Stock shall have the right (the “Holder Milestone Redemption Right”) to require, at any time on or after the Milestone Date, at such
Holder’s option, that the Corporation redeem all, but not less than all, of such Holder’s shares of Series B Preferred Stock, out of funds legally available therefor, at a purchase price (the “Milestone Redemption Price”)
for each share of Series B Preferred Stock equal to the sum of (A) the Liquidation Preference and (B) the Accrued Dividends of such share as of the applicable Milestone Redemption Date. 

(ii) The Corporation shall have the right (the “Corporation Milestone Redemption Right”), at any time on or after the
Milestone Date, at the Corporation’s option, to redeem all, but not less than all, of the then issued and outstanding shares of Series B Preferred Stock, out of funds legally available therefor, at the applicable Milestone Redemption Price for
each issued and outstanding share of Series B Preferred Stock. 
 (b) Mechanics of Milestone Redemption. 

(i) The Holder Milestone Redemption Right shall be exercised by a Holder of Series B Preferred Stock requesting in writing delivered to
the Corporation that the Corporation redeem its shares of Series B Preferred Stock (a “Holder Milestone Redemption Request”). Each Holder Milestone Redemption Request must specify a Designated Milestone Redemption Date selected by
the Milestone Redemption Requesting Holder for the redemption of its shares of Series B Preferred Stock, and the Corporation shall redeem, or shall cause to be redeemed, such shares of Series B Preferred Stock then issued and outstanding on such
specified Designated Milestone Redemption Date. As promptly as practicable (but in no event more than 10 business days) following receipt of a Holder Milestone Redemption Request, the Corporation shall deliver, or shall cause to be delivered, a
notice by first class mail, postage prepaid, addressed to each Milestone Redemption Requesting Holder as it appears in the Register as of the date of such notice, stating the following: (A) the expected aggregate Milestone Redemption
Price of such Holder’s shares of Series B Preferred Stock as of the Designated Milestone Redemption Date (it 

  
 18 

 
being understood that the actual Milestone Redemption Price will be determined as of the actual Milestone Redemption Date), (B) the name of the Redemption Agent to whom, and the
address of the place where, the Series B Preferred Stock is to be surrendered for payment of the applicable Milestone Redemption Price and a description of the procedure that such Holder must follow to have its shares of Series B Preferred Stock
redeemed; and (C) that Series B Preferred Dividends on any share to be redeemed will cease to accrue on such share’s actual Milestone Redemption Date. 
 (ii) The Corporation shall (i) exercise the Corporation Milestone Redemption Right by delivering, or causing to be delivered, a notice of redemption by first class mail, postage prepaid, addressed to
the Holders of the Series B Preferred Stock as they appear in the Register as of the date of such notice, stating the following: (A) the Designated Milestone Redemption Date selected by the Corporation for the redemption of all then
issued and outstanding shares of Series B Preferred Stock; (B) the expected aggregate Milestone Redemption Price of such Holder’s shares of Series B Preferred Stock as of such Designated Milestone Redemption Date (it being
understood that the actual Milestone Redemption Price will be determined as of the actual Milestone Redemption Date); (C) the name of the Redemption Agent to whom, and the address of the place where, the Series B Preferred Stock is to be
surrendered for payment of the applicable Milestone Redemption Price and a description of the procedure that a Holder must follow to have its shares of Series B Preferred Stock redeemed; and (D) that Series B Preferred Dividends on any
share to be redeemed will cease to accrue on such share’s actual Milestone Redemption Date and (ii) redeem, or shall cause to be redeemed, all then issued and outstanding shares of Series B Preferred Stock on the Designated Milestone
Redemption Date specified in such notice. 
 (iii) On or prior to each Designated Milestone Redemption Date, the Corporation
shall deposit with the applicable Redemption Agent in trust funds consisting of cash or cash equivalents sufficient to pay the aggregate Milestone Redemption Price for all shares of Series B Preferred Stock to be redeemed on such Designated
Milestone Redemption Date; provided that if such payment is made on the Designated Milestone Redemption Date it must be received by the Redemption Agent by 10:00 a.m. New York City time, on such date. The deposit in trust with the Redemption
Agent shall be irrevocable as of the applicable Designated Milestone Redemption Date, except that the Corporation shall be entitled to receive from the Redemption Agent (i) the Milestone Redemption Price with respect to shares of Series
B Preferred Stock that are no longer to be redeemed, whether by conversion or otherwise, and (ii) the interest or other earnings, if any, earned on any such deposit. The Holders of the shares redeemed shall have no claim to such interest
or other earnings, and any funds so deposited with the Redemption Agent and unclaimed by the Holders of the Series B Preferred Stock entitled thereto at the expiration of one year from the applicable Designated Milestone Redemption Date, shall be
repaid, together with any interest or other earnings thereon, to the Corporation, and after any such repayment, the holders of the shares entitled to the funds so returned to the Corporation shall look only to the Corporation for such payment,
without interest. Notwithstanding the deposit of such funds with the Redemption Agent, the Corporation shall remain liable for the payment of the applicable Milestone Redemption Price to the extent such Milestone Redemption Price is not paid as
provided herein. If on or prior to the applicable Designated Milestone Redemption Date, the Corporation shall have deposited in accordance with this Section 7(b)(iii) money in immediately available funds, designated for the redemption of
the shares of Series B Preferred Stock to be redeemed on such 

  
 19 

 
Designated Milestone Redemption Date and sufficient to pay the aggregate Milestone Redemption Price as of such Designated Milestone Redemption Date for all such shares of Series B Preferred
Stock, such shares of Series B Preferred Stock shall no longer be deemed to be outstanding, and all powers, designations, preferences and other rights of the Holder thereof as a Holder of Series B Preferred Stock (except the right to receive from
the Corporation the Maturity Redemption Price) shall cease and terminate with respect to such shares. 
 (iv) The Redemption
Agent on behalf of the Corporation shall pay the applicable Milestone Redemption Price on the later to occur of (A) the applicable Designated Milestone Redemption Date and (B) the date on which surrender of the certificates
representing the shares of Series B Preferred Stock to be redeemed (properly endorsed or assigned for transfer, if the Corporation shall so require and if letters of transmittal and instructions therefor on reasonable terms are included in the
notice sent by the Corporation) occurs; provided that if such certificates are lost, stolen or destroyed, the Corporation may require such Holder to indemnify the Corporation, in a reasonable amount and in a reasonable manner, and post a
customary bond in respect of such indemnity, prior to paying such Milestone Redemption Price. 
 (v) If the funds of the
Corporation legally available to redeem shares of Series B Preferred Stock on a Designated Milestone Redemption Date are insufficient to redeem the total number of such shares required to be so redeemed, the Corporation shall to the fullest extent
permitted by applicable law (1) redeem, pro rata among the Holders of shares required to be so redeemed on such Designated Milestone Redemption Date, a number of shares of Series B Preferred Stock with an aggregate Maturity Redemption
Price equal to the maximum amount legally available for the redemption of such shares; (2) subject to and in accordance with the provisions of Section 11 and Section 13(a), use its best efforts, and take any and
all action necessary, to remove as soon as practicable any limitations or impediments to the Corporation’s ability to redeem the total number of shares of Series B Preferred Stock required to be so redeemed, including, without limitation,
(x) taking all actions required or permitted under Delaware law, (y) seeking to liquidate assets and otherwise seeking to raise sufficient funds legally available for the redemption of the shares of Series B Preferred Stock
required to be so redeemed and (z) seeking a merger or other sale of the Corporation that would provide for the redemption of the shares of Series B Preferred Stock required to be so redeemed and (3) redeem each and every
share of Series B Preferred Stock not redeemed in accordance with clause (1) of this paragraph at the applicable Milestone Redemption Price as soon as practicable to the extent it is able to make such redemption out of assets legally available
for the redemption of shares of Series B Preferred Stock; provided, however, that the failure to (A) deposit in accordance with Section 7(b)(iii) money in immediately available funds sufficient to pay the
aggregate Milestone Redemption Price as of a Designated Milestone Redemption Date for all shares of Series B Preferred Stock required to be redeemed on such Designated Milestone Redemption Date or (B) redeem on a Designated Milestone
Date shares of Series B Preferred Stock upon surrender of the certificates therefor in accordance with Section 7(b)(iv), shall constitute a Default. The inability of the Corporation to make a redemption payment for any reason shall not
relieve the Corporation from its obligation to effect any required redemption when, as and if permitted by law. In the event the officers or directors of the Corporation do not take the actions required in this Section 7 because they
reasonably believe, after consultation with outside legal counsel, that taking such action would violate their fiduciary duties, then no Holder of Series B Preferred Stock shall be 

  
 20 

 
entitled to, and none shall, make any claim against any such officers or directors in their individual capacities as a result of their failure or the Corporation’s failure to take such
actions; provided, that nothing herein shall relieve the Corporation from its obligations owed to the Holders of the Series B Preferred Stock provided herein and nothing herein shall preclude any Holder of Series B Preferred Stock from making
claims for monetary damages against the Corporation or seeking injunctions or other equitable remedies to cause the Corporation to fulfill its obligations hereunder. 
 (vi) From and after the Milestone Redemption Date with respect to any share of Series B Preferred Stock, such share of Series B Preferred Stock will no longer be deemed to be outstanding, and all powers,
designations, preferences and other rights of the Holder thereof as a Holder of Series B Preferred Stock shall cease and terminate with respect to such share. For the avoidance of doubt, notwithstanding anything contained herein to the contrary,
until a share of Series B Preferred Stock is redeemed by the payment in cash in full of the applicable Milestone Redemption Price under Section 7(a)(i) or Section 7(a)(ii) for such share, such share of Series B Preferred
Stock will remain outstanding and will be entitled to all of the powers, designations, preferences and other rights provided herein, including, without limitation, that such share (x) may be converted pursuant to Section 6
and, if not so converted, (y) shall (i) accrue and accumulate Series B Preferred Dividends and participate in Participating Dividends pursuant to Section 4 and (ii) entitle the Holder thereof to the
voting rights provided in Section 11; provided, that, any such shares that are converted pursuant to Section 6 shall not be entitled to receive any redemption payment. 

Section 8. Change of Control Redemption at the Option of the Holder. 

(a) Change of Control Redemption. 
 (i) In connection with a Change of Control described in Section 8(c)(i)(B), each Holder of Series B Preferred Stock shall have the right (exercisable at the Holder’s option) to require,
by request in writing to the Corporation during the period starting 50 days prior to the consummation of such Change of Control and ending on the date that is 10 days prior to the consummation of such Change of Control (such date of consummation,
the “Change of Control Date”), that the Corporation redeem (or that the acquiring or surviving Person in such Change of Control, if not the Corporation, redeem) (a “Change of Control Redemption”) all, but not less
than all, of such Holder’s shares of Series B Preferred Stock, out of funds legally available therefor, at a purchase price (the “Make Whole Change of Control Redemption Price”) for any share of Series B Preferred Stock equal
to (A) if the applicable Change of Control Redemption Date is prior to the fourth anniversary of the Original Issuance Date, the sum of (1) the Liquidation Preference plus the Accrued Dividends of such share as of the
applicable Change of Control Redemption Date and (2) an amount equal to the net present value (computed using a discount rate equal to the Treasury Rate plus 50 basis points) of the sum of all Series B Preferred Stock Dividends that
would otherwise be payable on such share of Series B Preferred Stock on and after the applicable Change of Control Redemption Date to and including the fourth anniversary of the Original Issuance Date, assuming the Corporation chose to pay such
dividends in cash, or (B) if the applicable Change of Control Redemption Date is on or after the fourth anniversary of the Original Issuance Date, the sum of (1) the Liquidation Preference and (2) the Accrued
Dividends of such share as of the 

  
 21 

 
applicable Change of Control Redemption Date. The Corporation shall effect such Change of Control Redemptions, or cause such Change of Control Redemptions to be effected, on the applicable Change
of Control Dates. 
 (ii) In connection with a Change of Control described in Section 8(c)(i)(A), each Holder of
Series B Preferred Stock shall have the right (exercisable at the Holder’s option) to require, by request in writing to the Corporation during the period starting on the date on which the consummation of such Change of Control is publicly
disclosed and ending on the date that is designated by the Corporation (the “Designated Change of Control Redemption Date”) that is not less than 30 nor more than 45 days after the date of the Change of Control Notice in connection
with such Change of Control, that the Corporation redeem each such Holder’s shares of Series B Preferred Stock, out of funds legally available therefor, at the applicable Make Whole Change of Control Redemption Price, whereupon the Corporation
shall effect such Change of Control Redemptions, or cause such Change of Control Redemptions to be effected, on the applicable Designated Change of Control Redemption Dates. 
 (iii) In connection with a Change of Control described in Section 8(c)(i)(C), each Holder of Series B Preferred Stock shall have the right (exercisable at the Holder’s option) to require,
by request in writing to the Corporation during the period starting on the date on which the consummation of such Change of Control is publicly disclosed and ending on the applicable Designated Change of Control Redemption Date that is not less than
30 nor more than 45 days after the date of the Change of Control Notice in connection with such Change of Control, that the Corporation redeem each such Holder’s shares of Series B Preferred Stock, out of funds legally available therefor, at a
purchase price (the “Other Change of Control Redemption Price” ) for any share of Series B Preferred Stock equal to 101% of the sum of (1) the Liquidation Preference and (2) the Accrued Dividends of such
share as of the applicable Change of Control Redemption Date. The Corporation shall effect such Change of Control Redemptions, or cause such Change of Control Redemptions to be effected, on the applicable Designated Change of Control Redemption
Dates. 
 (b) Mechanics of Change of Control Redemption. 

(i) The Corporation shall deliver, or shall cause to be delivered, written notice of a Change of Control (a “Change of Control
Notice”), by first class mail, postage prepaid, as promptly as practicable (but, (x) with respect to a Change of Control described in Section 8(c)(i)(B), in no event later than 60 days prior to such Change of Control
and (y) with respect to a Change of Control described in Section 8(c)(i)(A) or Section 8(c)(i)(C), in no event later than 5 days following the public disclosure of the consummation of such Change of Control),
addressed to the Holders of the Series B Preferred Stock as they appear in the Register as of the date of such Change of Control Notice. Each Change of Control Notice must state: (A) a reasonably detailed summary of the circumstances
constituting the applicable Change of Control and the redemption right at the option of the Holders arising as a result thereof; (B) the applicable Change of Control Redemption Price; (C) with respect to (x) a
Change of Control described in Section 8(c)(i)(B), the applicable Change of Control Date or (y) a Change of Control described in Section 8(c)(i)(A) or Section 8(c)(i)(C), the applicable Designated
Change of Control Redemption Date; (D) that the Holder must exercise the redemption right on or prior to the applicable Change of Control Date or 

  
 22 

 
the applicable Designated Change of Control Redemption Date, as the case may be; (E) the name of the Redemption Agent to whom, and the address of the place where, the Series B
Preferred Stock are to be surrendered for payment of the applicable Change of Control Redemption Price and a description of the procedure that a Holder must follow to exercise its redemption right and (F) if such Change of Control is an
Applicable Non-Qualified Business Combination, (1) that the Change of Control is an Applicable Non-Qualified Business Combination, (2) the effect on a Holder’s shares of Series B Preferred Stock in the event such Holder
decides not to exercise its right to require the Corporation to redeem its shares of Series B Preferred Stock pursuant to this Section 8 and (3) the information set forth in clauses (C) and (D) of the final sentence
of Section 9(a)(ii). 
 (ii) On or prior to each Change of Control Date and each Designated Change of Control
Redemption Date, the Corporation shall, subject to Section 8(b)(iii), deposit with the Redemption Agent in trust funds consisting of cash or cash equivalents sufficient to pay the aggregate Change of Control Redemption Price for all
shares of Series B Preferred Stock to be redeemed on such Change of Control Date or such Designated Change of Control Redemption Date, as the case may be; provided that if such payment is made on the Change of Control Date or the Designated
Change of Control Redemption Date, as applicable, it must be received by the Redemption Agent by 10:00 a.m. New York City time, on such date. The deposit in trust with the Redemption Agent shall be irrevocable as of the applicable Change of Control
Date or the applicable Designated Change of Control Redemption Date, as the case may be, except that the Corporation shall be entitled to receive from the Redemption Agent (i) the Change of Control Redemption Price with respect to shares
of Series B Preferred Stock that are no longer to be redeemed, whether by conversion or otherwise; and (ii) the interest or other earnings, if any, earned on any such deposit. The Holders of the shares redeemed shall have no claim to
such interest or other earnings, and any funds so deposited with the Redemption Agent and unclaimed by the Holders of the Series B Preferred Stock entitled thereto at the expiration of one year from the applicable Change of Control Date or the
applicable Designated Change of Control Redemption Date, as the case may be, shall be repaid, together with any interest or other earnings thereon, to the Corporation, and after any such repayment, the holders of the shares entitled to the funds so
returned to the Corporation shall look only to the Corporation for such payment, without interest. Notwithstanding the deposit of such funds, the Corporation shall remain liable for the payment of the applicable Change of Control Redemption Price to
the extent such Change of Control Redemption Price is not paid as provided herein. 
 (iii) If the Corporation
(A) shall not have sufficient funds legally available under the DGCL for the redemption of all shares of Series B Preferred Stock that Holders of Series B Preferred Stock have requested be redeemed under Section 8(a)(i),
Section 8(a)(ii) or Section 8(a)(iii) (the “Required Number of Shares”) or (B) will be in violation of Specified Contract Terms (as defined below), to the extent still in effect and applicable at
such time, if it redeems the Required Number of Shares, the Corporation shall: (1) redeem, pro rata among the Holders of shares of Series B Preferred Stock that have requested their shares be redeemed, a number of shares of Series B
Preferred Stock with an aggregate Change of Control Redemption Price equal to the lesser of (y) the amount legally available for the redemption of shares of Series B Preferred Stock and (z) the largest amount that can be used
for such redemption not prohibited by Specified Contract Terms; (2) subject to and in accordance with the provisions of Section 11 and Section  

  
 23 

 
13(a), use its best efforts to eliminate any limitation or other impediment on the Corporation’s ability to redeem the Required Number of Shares as soon as practicable (including,
without limitation, seeking to refinance all indebtedness under the contracts containing the Specified Contract Terms, seeking to liquidate assets and otherwise seeking to raise sufficient funds legally available for the redemption of the Required
Number of Shares without violation of Specified Contract Terms, and seeking a merger or other sale of the Corporation that would provide for the redemption of the Required Number of Shares); and (3) redeem each and every share of Series
B Preferred Stock not redeemed because of the limitations described in clause (A) or clause (B) of this paragraph at the applicable Change of Control Redemption Price as soon as practicable to the extent it is able to make such redemption
out of assets legally available for the redemption of shares of Series B Preferred Stock and without violation of Specified Contract Terms; provided, however, that the failure to redeem on the applicable Change of Control Date all
shares of Series B Preferred Stock that Holders have requested be redeemed under Section 8(a)(i), or the failure to redeem on the applicable Designated Change of Control Redemption Date all shares of Series B Preferred Stock that Holders
have requested be redeemed under Section 8(a)(ii) or Section 8(a)(iii), shall constitute a Default. The inability of the Corporation to make a redemption payment for any reason shall not relieve the Corporation from its
obligation to effect any required redemption when, as and if permitted by law and Specified Contract Terms. As used in this paragraph, “Specified Contract Terms” means the covenants of the Corporation contained in
(x) the Amended Credit Agreement (as defined in the Investment Agreement) and the other Credit Documents (as defined in the Amended Credit Agreement), (y) the ABL Documentation (as defined in the Investment Agreement) and
(z) the Indenture (as defined in the Investment Agreement), in each case under clauses (x), (y) and (z) as the same shall be in effect following the Closing (as defined in the Investment Agreement) and not including any
subsequent amendment, restatement, refinancing, replacement or other modification thereof or any successor contract thereto and only for so long as such covenants shall be in effect. In the event the officers or directors of the Corporation do not
take the actions required in this Section 8 because they reasonably believe, after consultation with outside legal counsel, that taking such action would violate their fiduciary duties, then no Holder of Series B Preferred Stock shall be
entitled to, and none shall, make any claim against any such officers or directors in their individual capacities as a result of their failure or the Corporation’s failure to take such actions; provided, that nothing herein shall relieve
the Corporation from its obligations owed to the Holders of the Series B Preferred Stock provided herein and nothing herein shall preclude any Holder of Series B Preferred Stock from making claims for monetary damages against the Corporation or
seeking injunctions or other equitable remedies to cause the Corporation to fulfill its obligations hereunder. 
 (iv) From and
after the Change of Control Redemption Date with respect to any share of Series B Preferred Stock, such share of Series B Preferred Stock will no longer be deemed to be outstanding; and all powers, designations, preferences and other rights of the
Holder thereof as a Holder of Series B Preferred Stock shall cease and terminate with respect to such share. For the avoidance of doubt, notwithstanding anything contained herein to the contrary, until a share of Series B Preferred Stock is redeemed
by the payment in cash in full of the applicable Change of Control Redemption Price under Section 8(a)(i), Section 8(a)(ii) or Section 8(a)(iii) for such share, such share of Series B Preferred Stock will remain
outstanding and will be entitled to all of the powers, designations, preferences and other rights provided herein, including, without limitation, 

  
 24 

 
that such share (x) may be converted pursuant to Section 6 and, if not so converted, (y) shall (i) accrue and accumulate Series B Preferred
Dividends and participate in Participating Dividends pursuant to Section 4 and (ii) entitle the Holder thereof to the voting rights provided in Section 11; provided, that, any such shares that are converted
pursuant to Section 6 shall not be entitled to receive any redemption payment. 
 (c) Certain Definitions.

 (i) As used herein, “Change of Control” means the occurrence of any of the following events: 

(A) so long as at the time immediately prior to the consummation of such acquisition and, if such acquisition (or any transaction or
series of transactions leading to such acquisition) is approved, or recommended to the stockholders of the Corporation, by the Board of Directors, at the time such acquisition is approved or recommended by the Board of Directors, (x) the
Investor does not Beneficially Own, directly or indirectly, 45% or more of the combined voting power of the Outstanding Corporation Voting Stock and (y) the aggregate number of votes that the Investor Directors are entitled to cast do
not constitute a majority of the total number of votes that can be cast by all of the members of the Board of Directors or the aggregate number of votes that are cast by Investor Directors do not constitute a majority of the total number of votes
that could be cast by the directors constituting the quorum granting such approval or recommendation, any Person (other than any Investor or any of its Affiliates) acquires Beneficial Ownership, directly or indirectly, of 50% or more of the combined
voting power of the Outstanding Corporation Voting Stock; 
 (B) so long as at the time such Business Combination is approved,
or recommended to the stockholders of the Corporation, by the Board of Directors (if so approved or recommended) and at the time immediately prior to the consummation of such Business Combination (x) the Investor does not Beneficially
Own, directly or indirectly, 45% or more of the combined voting power of the Outstanding Corporation Voting Stock and (y) the aggregate number of votes that the Investor Directors are entitled to cast do not constitute a majority of the
total number of votes that can be cast by all of the members of the Board of Directors or the aggregate number of votes that are cast by Investor Directors do not constitute a majority of the total number of votes that could be cast by the directors
constituting the quorum granting such approval or recommendation, the consummation of a Non-Qualified Business Combination; or 

(C) so long as at the time such “change of control” is approved, or recommended to the stockholders of the Corporation, by the
Board of Directors (if so approved or recommended) and at the time immediately prior to the consummation of such “change of control” (x) the Investor does not Beneficially Own, directly or indirectly, 45% or more of the
combined voting power of the Outstanding Corporation Voting Stock and (y) the aggregate number of votes that the Investor Directors are entitled to cast do not constitute a majority of the total number of votes that can be cast by all of
the members of the Board of Directors or the aggregate number of votes that are cast by Investor Directors do not constitute a majority of the total number of votes that could be cast by the directors constituting the quorum granting such approval
or recommendation, any event that would not otherwise constitute a Change of Control pursuant to Section 8(c)(i)(A) or Section 8(c)(i)(B) but would constitute a “change of control” for purposes of (i) prior to
any 

  
 25 

 
amendment, restatement, refinancing, replacement or other modification, or the termination or expiration thereof, (1) the Amended Credit Agreement (as defined in the Investment
Agreement) and the Other Credit Documents (as defined in the Investment Agreement) or (2) the ABL Documentation (as defined in the Investment Agreement) (the “Closing Debt Agreements”) or (ii) any subsequent
amendment, restatement, refinancing, replacement or other modification of any Closing Debt Agreement or any successor contract to any Closing Debt Agreement (each a “Successor Debt Agreement”) assuming that the events constituting a
“change of control” under any Successor Debt Agreement are the same as were in effect in the applicable Closing Debt Agreement as of the date of Closing (as defined in the Investment Agreement). 

(ii) The terms “Beneficially Own” and “Beneficial Ownership” are used herein as defined in Rules 13d-3
and 13d-5 under the Exchange Act as in effect on the Original Issuance Date, but without taking into account any contractual restrictions or limitations on voting or other rights; provided, that the Investor and its Affiliates shall not be
deemed to “Beneficially Own,” or have “Beneficial Ownership” of, any securities of the Corporation held or owned by an Investor Portfolio Company. 
 Section 9. Certain Business Combinations. 
 (a) Automatic Conversion
Following Certain Business Combinations. 
 (i) Without limiting the provisions of (or the Holders’ rights under)
Section 8, if a Non-Qualified Business Combination is consummated pursuant to which the Common Stock will be converted into the right to receive cash, securities or other property of a Person other than the Corporation (an
“Applicable Non-Qualified Business Combination”), then (x) upon the consummation of an Applicable Non-Qualified Business Combination that is not a Change of Control described in Section 8(c)(i)(B), the shares
of the Holders of Series B Preferred Stock shall or (y) upon the consummation of an Applicable Non-Qualified Business Combination that is a Change of Control described in Section 8(c)(i)(B), the shares of Series B Preferred
Stock held by each Holder that has not exercised its right to a Change of Control Redemption pursuant to Section 8(a) shall, without the consent of such Holder, automatically convert into the right to receive the kind and amount of cash,
securities or other property, if any (the “Exchange Property”), receivable in such Applicable Non-Qualified Business Combination by a holder of Common Stock (that was not the counterparty to the Applicable Non-Qualified Business
Combination or an affiliate of such counterparty) holding that number of shares of Common Stock into which such Holder’s shares of Series B Preferred Stock would have been convertible (pursuant to Section 6 without regard to any of
the limitations on convertibility contained therein) immediately prior to the consummation of such Applicable Non-Qualified Business Combination. In the event that holders of shares of Common Stock have the opportunity to elect the form of
consideration to be received in an Applicable Non-Qualified Business Combination, each Holder shall have the same opportunity to elect the form of consideration that each Holder is entitled to receive. 

(ii) The Corporation (or any successor) shall, as promptly as practicable, but in no event later than 5 business days following the
consummation of an Applicable Non-Qualified Business Combination, deliver written notice of the occurrence of such Applicable Non-Qualified Business Combination, by first class mail, postage prepaid, addressed to the Holders as they

  
 26 

 
appear in the records of the Corporation as of the date of such notice; provided, however, the Change of Control Notice delivered pursuant to and in accordance with
Section 8(b)(i) prior to an Applicable Non-Qualified Business Combination that is a Change of Control described in Section 8(c)(i)(B) shall satisfy the Corporation’s obligation to deliver notice pursuant to this
Section 9(a)(ii). Each notice must state: (A) a reasonably detailed summary of the circumstances constituting the Applicable Non-Qualified Business Combination and the automatic conversion of the Holders’ shares of
Series B Preferred Stock arising as a result thereof; (B) the date of consummation of the Applicable Non-Qualified Business Combination; (C) the kind and amount of the cash, securities or other property that constitutes the
Exchange Property and of the right, if applicable, to elect the form of consideration to be received; and (D) the name of the paying agent or exchange agent, if any, to whom, and the address of the place where, the Series B Preferred
Stock are to be surrendered for payment of the Exchange Property and a description of the procedure that a Holder must follow to exchange its shares of Series B Preferred Stock and, if applicable, to elect the form of consideration to be received.

 (b) Mechanics of Automatic Conversion. 
 (i) Each applicable Holder of Series B Preferred Stock shall surrender to the Corporation (or any successor) the certificates representing its shares of Series B Preferred Stock to the Transfer Agent at
the address stated in the notice provided pursuant to Section 9(a)(ii) or Section 8(b)(i), as the case may be, accompanied by written notice of such Holder’s election of the form of consideration to be received, if
applicable, and specifying the name or names (with address or addresses) in which a certificate or certificates for shares of securities that constitute part of the Exchange Property, if any, are to be issued and (if so required by the Corporation
(or any successor) or the Transfer Agent) by a written instrument or instruments of transfer in form reasonably satisfactory to the Corporation (or any successor) or the Transfer Agent duly executed by the Holder or its legal representative.

 (ii) The Transfer Agent on behalf of the Corporation (or any successor) shall pay the applicable Exchange Property as
promptly as practicable upon surrender of the certificates representing the shares of Series B Preferred Stock to be exchanged; provided that if such certificates are lost, stolen or destroyed, the Corporation (or any successor) may require
the Holder to indemnify the Corporation (or any successor), in a reasonable amount and in a reasonable manner, and post a customary bond in respect of such indemnity, prior to paying such Exchange Property. 

(iii) From and after the Automatic Conversion Date, (A) shares of Series B Preferred Stock to be exchanged for Exchange
Property will no longer be deemed to be outstanding, and all powers, designations, preferences and other rights of the Holder thereof as a Holder of Series B Preferred Stock (except the right to receive from the Corporation (or any successor) the
Exchange Property) shall cease and terminate with respect to such shares and (B) the Person entitled to receive shares of securities that constitute part of the Exchange Property, if any, shall be treated for all purposes as having
become the record holder of those shares at that time. 

  
 27 

 Section 10. Adjustments to Conversion Price. 

(a) Adjustments to Conversion Price. Except as provided in Section 10(e), the Conversion Price shall be subject to the
following adjustments, so long as, in the case of clauses (iii) – (v) of this Section 10(a), at the time the relevant event referred to in such clause is approved, or recommended to the stockholders of the Corporation, by
the Board of Directors either (x) the aggregate number of votes that the Investor Directors are entitled to cast do not constitute a majority of the total number of votes that can be cast by all of the members of the Board of Directors
or the aggregate number of votes that are cast by Investor Directors do not constitute a majority of the total number of votes that could be cast by the directors constituting the quorum granting such approval or recommendation or (y) if
the aggregate number of votes that the Investor Directors are entitled to cast do constitute a majority of the total number of votes that can be cast by all of the members of the Board of Directors or the aggregate number of votes that are cast by
Investor Directors do constitute a majority of the total number of votes that could be cast by the directors constituting the quorum granting such approval or recommendation, (1) so long as at least one Unaffiliated Shareholder Director was
part of the quorum granting such approval or recommendation, either (A) a majority of the Unaffiliated Shareholder Directors voting with respect to such approval or recommendation voted in favor of such approval or recommendation or
(B) each Unaffiliated Shareholder Director that was a part of the quorum granting such approval or recommendation abstained from voting with respect thereto or (2) a majority of the Independent Directors did not in good faith oppose such
approval or recommendation on the merits (without regard to the impact of such approval or recommendation, or the withholding thereof, on the Investor): 
 (i) Stock Dividends and Distributions. If the Corporation declares a dividend or makes a distribution on the Common Stock payable in shares of Common Stock, then the Conversion Price in effect at
the opening of business on the Ex-Date for such dividend or distribution shall be adjusted to the price determined by multiplying the Conversion Price at the opening of business on such Ex-Date by the following fraction: 

OS0 

OS1 

Where, 
 OS0 = the
number of shares of Common Stock outstanding at the close of business on the Business Day immediately preceding the Ex-Date for such dividend or distribution. 

OS1 = the sum of the number of shares of Common Stock outstanding at the close of business on the Business Day
immediately preceding the Ex-Date for such dividend or distribution plus the total number of shares of Common Stock constituting such dividend or distribution. 
 If any dividend or distribution described in this Section 10(a)(i) is declared but not so paid or made, the Conversion Price shall be readjusted, effective as of the date and time the Board of
Directors publicly announces its decision not to make such dividend or distribution, to such Conversion Price that would be in effect if such dividend or distribution had not been declared. 

  
 28 

 (ii) Subdivisions, Splits and Combination of the Common Stock. If the Corporation
subdivides, splits or combines the shares of Common Stock, then the Conversion Price in effect immediately prior to the effective date of such share subdivision, split or combination shall be adjusted to the price determined by multiplying the
Conversion Price in effect immediately prior to the effective date of such share subdivision, split or combination by the following fraction: 
 OS0 
 OS1 

Where, 
 OS0 = the number
of shares of Common Stock outstanding immediately prior to the effective date of such share subdivision, split or combination. 
 OS1 = the number
of shares of Common Stock outstanding immediately after the opening of business on the effective date of such share subdivision, split or combination. 
 If any subdivision, split or combination described in this Section 10(a)(ii) is announced but the outstanding shares of Common Stock are not subdivided, split or combined, the Conversion Price
shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to subdivide, split or combine the outstanding shares of Common Stock, to such Conversion Price that would be in effect if such subdivision,
split or combination had not been announced. 
 (iii) Issuance of Common Stock, Convertible Securities and Options.
Subject to Section 10(b), if the Corporation issues or sells any Common Stock, Convertible Securities or Options other than Excluded Stock without consideration or for consideration per share less than the Applicable Current Market
Price, then the Conversion Price in effect immediately prior to such issuance or sale shall be adjusted to the price determined by multiplying the Conversion Price in effect immediately prior to such issuance or sale by the following fraction:

 OS0 + (X/ ACMP) 

OS0 + Y 
 Where, 
 OS0 = the number of shares of Common Stock outstanding immediately prior to
the date of such issuance or sale. 
 ACMP = the Applicable Current Market Price. 

X = the aggregate consideration received by the Corporation for the number of shares of Common Stock so issued or sold.

 Y = the number of shares of Common Stock so issued or sold. 

  
 29 

 For the purposes of any adjustment of the Conversion Price pursuant to this
Section 10(a)(iii), the following provisions shall be applicable: 
 (A) In the case of the issuance of Common Stock
for cash, the amount of the consideration received by the Corporation shall be deemed to be the gross amount of the cash proceeds received by the Corporation for such Common Stock without any deduction of brokerage, transaction, acquisition,
advisory, due diligence, origination or similar fees, including underwriting discounts fees or commissions allowed, paid or incurred by the Corporation in connection with the issuance and sale thereof. 

(B) In the case of the issuance of Common Stock (other than upon the conversion of Convertible Securities) for a consideration in whole
or in part other than cash, including securities acquired in exchange therefor (other than securities by their terms so exchangeable), the consideration other than cash shall be deemed to be the fair value thereof as determined by a firm of
independent public accountants or an independent appraiser, in each case, of recognized national standing selected by the Board of Directors by action of a majority of the Independent Directors (“Independent Majority”) and consented
to by the Holder of a majority of the outstanding shares of Series B Preferred Stock (if there is one such Person or Group (such consent not to be unreasonably withheld)), provided that such fair value, together with any cash or other
consideration received in respect of the Common Stock, shall not for the purposes hereof in any event exceed the aggregate Applicable Current Market Price of the shares of Common Stock being issued as of the date the Board of Directors authorizes
the issuance of such shares. 
 (C) In the case of the issuance of (x) Options for Common Stock (whether or not at
the time exercisable) or (y) Convertible Securities (whether or not at the time so convertible or exchangeable) or Options for Convertible Securities (whether or not at the time exercisable): 

(1) the aggregate maximum number of shares of Common Stock deliverable upon exercise of Options for Common Stock shall be deemed to have
been issued at the time such Options are issued and for a consideration equal to the consideration (determined in the manner provided in Section 10(a)(iii)(A) and Section 10(a)(iii)(B)), if any, received by the Corporation
upon the issuance of such Options plus the minimum purchase price provided in such Options for the Common Stock covered thereby; 
 (2) the aggregate maximum number of shares of Common Stock deliverable upon conversion of or in exchange for Convertible Securities, or upon the exercise of Options for Convertible Securities and the
subsequent conversion or exchange of the Convertible Securities issued upon the exercise thereof, shall be deemed to have been issued at the time such Convertible Securities were issued or such Options for Convertible Securities were issued and for
a consideration equal to the consideration, if any, received by the Corporation for any such Convertible Securities or Options for Convertible Securities (excluding any cash received on account of accrued interest or accrued dividends), plus the
additional consideration (determined in the manner provided in Section 10(a)(iii)(A) and Section 10(a)(iii)(B)), if any, to be received by the Corporation upon the conversion or exchange of such Convertible Securities, or
upon the exercise of such Options for Convertible Securities and the subsequent conversion or exchange of the Convertible Securities issued upon the exercise thereof; 

  
 30 

 (3) on any change in the number of shares of Common Stock deliverable upon exercise of any
such Options or conversion or exchange of such Convertible Securities or any change in the consideration to be received by the Corporation upon such exercise, conversion or exchange, the Conversion Price as then in effect shall forthwith be
readjusted to such Conversion Price as would have been obtained had an adjustment been made upon the issuance of such Options not exercised prior to such change, or of such Convertible Securities not converted or exchanged prior to such change, upon
the basis of such change; and 
 (4) if the Conversion Price shall have been adjusted upon the issuance of any such Options or
Convertible Securities, no further adjustment of such Conversion Price shall be made for the actual issuance of Common Stock upon the exercise, conversion or exchange thereof. 

(D) For the avoidance of doubt, the number of shares of Common Stock outstanding immediately prior to the date of any issuance or sale
of Common Stock, Convertible Securities or Options shall include only the number of shares of Common Stock actually outstanding as of such time and shall not include any shares of Common Stock deliverable upon (i) conversion of or in
exchange for Convertible Securities, (ii) exercise of Options for Common Stock or (iii) exercise of Options for Convertible Securities and the subsequent conversion or exchange of the Convertible Securities issued upon the
exercise thereof. 
 (iv) Other Distributions. If the Corporation distributes to all holders of shares of Common Stock
evidences of indebtedness, shares of capital stock, securities, cash or other assets (excluding (a) any cash dividends to the extent a corresponding cash dividend is paid on the Series B Preferred Stock pursuant to
Section 4(a)(i), (b) dividends or distributions referred to in Section 10(a)(i), (c) Convertible Securities or Options referred to in Section 10(a)(iii) or (d) any dividend of
shares of capital stock of any class or series, or similar equity interests, of or relating to a Subsidiary of the Corporation or other business unit in the case of certain spin-off transactions as described below), then the Conversion Price in
effect immediately prior to the Ex-Date for such distribution shall be adjusted to the price determined by multiplying the Conversion Price in effect immediately prior to the Ex-Date for such distribution by the following fraction: 

SP0 – FMV 

SP0 

Where, 
 SP0 = the
Current Average Market Price per share of Common Stock on the date immediately prior to the Ex-Date for such distribution. 
 FMV = the fair market value of the portion of the distribution applicable to one share of Common Stock on the Ex-Date for such distribution, in the case of a non-cash distribution or with respect to the
non-cash portion of a distribution, if any, as determined by a firm of independent public accountants or an independent appraiser, in each case, of recognized national standing selected by the Board of Directors by action of an Independent Majority
and consented to by the Holder of a majority of the outstanding shares of Series B Preferred Stock (if there is one such Person or Group (such consent not 

  
 31 

 
to be unreasonably withheld)), provided that such value shall not for the purposes hereof in any event be equal to or greater than the Current Average Market Price per share of Common
Stock on such date. 
 In a “spin-off,” where the Corporation makes a distribution to all holders
of shares of Common Stock consisting of capital stock of any class or series, or similar equity interests of, or relating to, a Subsidiary of the Corporation or other business unit, the Conversion Price will be adjusted on the 15th Trading Day after the effective date of the distribution by
multiplying such Conversion Price in effect immediately prior to such 15th Trading Day by the following fraction: 

      MP0      

 MP0 + MPs 

Where, 
 MP0 = the
average of the Closing Prices of the Common Stock over the first ten Trading Days commencing on and including the fifth Trading Day following the effective date of such distribution. 

MPs = the average of the Closing Prices of the capital stock or equity interests representing the portion of the distribution
applicable to one share of Common Stock over the first ten Trading Days commencing on and including the fifth Trading Day following the effective date of such distribution, or, if not traded on a national or regional securities exchange or
over-the-counter market, the fair market value of the capital stock or equity interests representing the portion of the distribution applicable to one share of Common Stock on such date as determined by a firm of independent public accountants or an
independent appraiser, in each case, of recognized national standing selected by the Board of Directors by action of an Independent Majority and consented to by the Holder of a majority of the outstanding shares of Series B Preferred Stock (if there
is one such Person or Group (such consent not to be unreasonably withheld)). 
 In the event that such
distribution described in this Section 10(a)(iv) is not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay or make such dividend or
distribution, to the Conversion Price that would then be in effect if such dividend or distribution had not been declared. 

(v) Certain Repurchases of Common Stock. If the Corporation effects a Pro Rata Repurchase of Common Stock which involves the
payment by the Corporation of consideration per share of Common Stock that exceeds the Current Average Market Price per share of Common Stock on the Trading Day next succeeding the Effective Date of such Pro Rata Repurchase (provided that if
part or all of the consideration is not cash, the fair market value of the non-cash consideration shall be determined by a firm of independent public accountants or an independent appraiser, in each case, of recognized national standing selected by
the Board of Directors by action of an Independent Majority and consented to by the Holders of a majority of the outstanding shares of Series B Preferred Stock (if there is one such Person or Group (such consent not to be unreasonably withheld))),
then the Conversion Price in effect immediately prior to the 

  
 32 

 
Effective Date of such Pro Rata Repurchase shall be adjusted (such adjustment to become effective immediately prior to the opening of business on the day following the Effective Date of such Pro
Rata Repurchase) by multiplying the Conversion Price in effect immediately prior to the Effective Date of such Pro Rata Repurchase by the following fraction: 

      OS0 x SP0      

 AC + (SP0 x OS1) 

Where, 
 SP0 = the
Current Average Market Price on the Trading Day immediately preceding the first public announcement of the intent to effect such Pro Rata Repurchase. 

OS0 = the number of shares of Common Stock outstanding at the Effective Date of such Pro Rata Repurchase, including, if
applicable, any shares validly tendered and not withdrawn or exchanged shares. 
 OS1= the number of shares of Common Stock outstanding at the Effective Date
of such Pro Rata Repurchase, including, if applicable, any shares validly tendered or exchanged and not withdrawn, minus the number of shares purchased in such Pro Rata Repurchase (which shares shall equal the Purchased Shares (as defined below) if
such Pro Rata Repurchase is effected pursuant to a tender offer or exchange offer). 
 AC = the aggregate cash
and fair market value of the other consideration payable in such Pro Rata Repurchase, in the case of non-cash consideration, as determined by a firm of independent public accountants or an independent appraiser, in each case, of recognized national
standing selected by the Board of Directors by action of an Independent Majority and consented to by the Holders of a majority of the outstanding shares of Series B Preferred Stock (if there is one such Person or Group (such consent not to be
unreasonably withheld)), based, in the case of a tender offer or exchange offer, on the number of shares actually accepted for purchase (the “Purchased Shares”). 

In the event that the Corporation, or one of its Affiliates, is obligated to purchase shares of Common Stock pursuant to any such Pro
Rata Repurchase, but the Corporation, or such Affiliate, is permanently prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Price shall be readjusted to be such Conversion Price
that would then be in effect if such Pro Rata Repurchase had not been made. 
 (vi) Rights Plans. To the extent that the
Corporation has a rights plan in effect with respect to the Common Stock on any Conversion Date, upon conversion of any shares of the Series B Preferred Stock, the Holders will receive, in addition to the shares of Common Stock, the rights under the
rights plan, unless, prior to such Conversion Date, the rights have separated from the shares of Common Stock, in which case the Conversion Price will be adjusted at the time of separation as if the Corporation had issued the rights to all holders
of the Common Stock in an issuance triggering an adjustment pursuant to Section 10(a)(iii), subject to readjustment in the event of the expiration, termination or redemption of such rights. 

  
 33 

 (b) Adjustments Upon Certain Issuances of Common Stock, Convertible Securities and
Options. Except as provided in Section 10(e), if during the three year period immediately following the Original Issuance Date the Corporation issues or sells any Common Stock, Convertible Securities or Options other than Excluded
Stock without consideration or for consideration per share less than the Conversion Price in effect immediately prior to such issuance or sale at a time when such Conversion Price is greater than the Applicable Current Market Price, so long as at
the time that such issuance or sale is approved, or recommended to stockholders of the Corporation, by the Board of Directors either (x) the aggregate number of votes that the Investor Directors are entitled to cast do not constitute a
majority of the total number of votes that can be cast by all of the members of the Board of Directors and the aggregate number of votes that are cast by Investor Directors do not constitute a majority of the total number of votes that could be cast
by the directors constituting the quorum granting such approval or recommendation or (y) if the aggregate number of votes that the Investor Directors are entitled to cast do constitute a majority of the total number of votes that can be
cast by all of the members of the Board of Directors or the aggregate number of votes that are cast by Investor Directors do constitute a majority of the total number of votes that could be cast by the directors constituting the quorum granting such
approval or recommendation, (1) a majority of the Unaffiliated Shareholder Directors voted in favor of such approval or recommendation or (2) a majority of the Independent Directors did not in good faith oppose such approval or
recommendation on the merits (without regard to the impact of such approval or recommendation, or the withholding thereof, on the Investor) and the Unaffiliated Shareholder Directors shall have received a certificate of a majority of the CD&R
Directors and the Other Investor Directors (as defined in the Stockholders Agreement) certifying that, in the good faith judgment of such majority of the CD&R Directors and Other Investor Directors, such issuance or sale is in the best interests
of the Corporation, then in lieu of any adjustment pursuant to Section 10(a)(iii), the Conversion Price in effect immediately prior to such issuance or sale shall be adjusted to the price determined by multiplying such Conversion Price
by the following fraction: 
 OS 0 + (X/ P 0) 

OS 0 + Y 
 Where, 
 OS0 = the number of shares of Common Stock outstanding immediately prior to
the date of such issuance or sale. 
 P0 = the Conversion Price in effect immediately prior to such issuance or
sale. 
 X = the aggregate consideration received by the Corporation for the number of shares of Common Stock so
issued or sold. 
 Y = the number of shares of Common Stock so issued or sold. 

For the purposes of any adjustment of the Conversion Price pursuant to this Section 10(b), the provisions set
forth in Section 10(a)(iii)(A), Section 10(a)(iii)(B), Section 10(a)(iii)(C) and Section 10(a)(iii)(D) shall apply. 

  
 34 

 (c) Other Adjustments. 

(i) The Corporation may make decreases in the Conversion Price, in addition to any other decreases required by this
Section 10, if the Board of Directors by action of an Independent Majority deems it advisable to avoid or diminish any income tax to holders of the Common Stock resulting from any dividend or distribution of shares of Common Stock (or
issuance of Options for Common Stock) or from any event treated as such for income tax purposes or for any other reason. 
 (ii)
If the Corporation takes any action affecting the Common Stock, other than an action described in Section 10(a) or Section 10(b), which upon a determination by the Board of Directors by action of an Independent Majority, such
determination intended to be a “fact” for purposes of Section 151(a) of the DGCL, would materially adversely affect the conversion rights of the Holders of shares of Series B Preferred Stock, the Conversion Price shall be adjusted, to
the extent permitted by law, in such manner, if any, and at such time, as the Board of Directors by action of an Independent Majority determines in good faith to be equitable in the circumstances. 

(d) Successive Adjustments. Successive adjustments in the Conversion Price shall be made, without duplication, whenever any event
specified in Section 10(a), Section 10(b), Section 10(c) or Section 10(e) shall occur. 
 (e) Rounding of Calculations; Minimum Adjustments. All adjustments to the Conversion Price shall be calculated to the nearest one-tenth
(1/10th) of a cent. No adjustment in the Conversion
Price shall be required if such adjustment would be less than $0.01; provided, that any adjustments which by reason of this Section 10(e) are not required to be made shall be carried forward and taken into account in any
subsequent adjustment; provided, further that on any Conversion Date adjustments to the Conversion Price will be made with respect to any such adjustment carried forward and which has not been taken into account before such date.

 (f) Statement Regarding Adjustments; Notices. Whenever the Conversion Price is to be adjusted in accordance with one
or more of Section 10(a), Section 10(b) or Section 10(c), the Corporation shall: (i) compute the Conversion Price in accordance with Section 10(a), Section 10(b) or
Section 10(c), taking into account the one cent threshold set forth in Section 10(e); (ii) (x) in the event that the Corporation shall give notice or make a public announcement to the holders of Common Stock of
any action of the type described in one or more of Section 10(a) or Section 10(b) (but only if the action of the type described in one or more of Section 10(a) or Section 10(b) would result in an
adjustment to the Conversion Price or a change in the type of securities or property to be delivered upon conversion of the Series B Preferred Stock), the Corporation shall, at the time of such notice or announcement, and in the case of any action
which would require the fixing of a record date, at least ten days prior to such record date, give notice to each Holder by mail, first class postage prepaid, at the address appearing in the Corporation’s records, which notice shall specify the
record date, if any, with respect to any such action, the approximate date on which such action is to take place and the facts with respect to such action as shall be reasonably necessary to indicate the effect on the Conversion Price and the
number, kind or class of shares or other securities or property which shall be deliverable upon conversion or redemption of the Series B Preferred Stock or (y) in the event that the Corporation does not give notice or make a public announcement
as set forth in subclause (x) of this clause (ii), the Corporation shall, as soon as practicable following the occurrence of an event that requires an 

  
 35 

 
adjustment to the Conversion Price pursuant to one or more of Section 10(a), Section 10(b) or Section 10(c), taking into account the one cent threshold set
forth in Section 10(e) (or if the Corporation is not aware of such occurrence, as soon as practicable after becoming so aware), provide, or cause to be provided, a written notice to the Holders of the occurrence of such event, in
the same manner and with the same detail as the notice set forth in subclause (x) of this clause (ii); and (iii) whenever the Conversion Price shall be adjusted pursuant to one or more of Section 10(a),
Section 10(b) or Section 10(c), the Corporation shall, as soon as practicable following the determination of the revised Conversion Price, (x) file at the principal office of the Corporation, a statement showing
in reasonable detail the facts requiring such adjustment, the Conversion Price that shall be in effect after such adjustment and the method by which the adjustment to the Conversion Price was determined and (y) cause a copy of such
statement to be sent in the manner set forth in subclause (x) of clause (ii) to each Holder. 
 (g) Certain
Adjustment Rules. If an adjustment in the Conversion Price made hereunder would reduce the Conversion Price to an amount below par value of the Common Stock, then such adjustment in Conversion Price made hereunder shall reduce the Conversion
Price to the par value of the Common Stock. As a condition precedent to the taking of any action which would require an adjustment pursuant to this Section 10, the Corporation shall use its best efforts to take any and all actions which
may be necessary, including, without limitation, obtaining regulatory, New York Stock Exchange (or such exchange or automated quotation system on which the Common Stock is then listed) or stockholder approvals or exemptions, in order that the
Corporation may thereafter validly and legally issue as fully paid and nonassessable all shares of Common Stock issuable upon conversion of the Series B Preferred Stock. 
 Section 11. Voting Rights. 
 (a) General. The Holders of shares of
Series B Preferred Stock shall be entitled to vote with the holders of the Common Stock on all matters submitted to a vote of stockholders of the Corporation, except as otherwise provided herein or as required by applicable law, voting together with
the holders of Common Stock as a single class. For such purposes, each Holder shall be entitled to a number of votes in respect of the shares of Series B Preferred Stock owned of record by it equal to the number of shares of Common Stock into which
such shares of Series B Preferred Stock could be converted (assuming that all of the then issued and outstanding shares of Series B Preferred Stock could be converted into shares of Common Stock on the record date in respect of such vote) as of the
record date for the determination of stockholders entitled to vote on such matters or, if no such record date is established, as of the date such vote is taken or any written consent of stockholders is solicited. The Holders of shares of Series B
Preferred Stock shall be entitled to notice of any stockholders’ meeting in accordance with the Certificate of Incorporation and the By-laws as if they were holders of record of Common Stock for such meeting. 

(b) Class Voting Rights. So long as any shares of Series B Preferred Stock are outstanding, in addition to any other vote required
by applicable law, the Corporation may not take any of the following actions (including by means of merger, consolidation, reorganization, recapitalization or otherwise) without the prior affirmative vote or written consent of the Holders
representing at least a majority of the then issued and outstanding shares of Series B Preferred Stock, voting together as a separate class: 

  
 36 

 (i) any amendment, alteration, repeal or other modification of any provision of the
Certificate of Incorporation, this Certificate or the By-laws that would alter or change the terms or the powers, preferences, rights or privileges of the Series B Preferred Stock so as to affect them adversely; 

(ii) any authorization, creation, increase in the authorized amount of, or issuance of any class or series of Senior Securities or any
security convertible into, or exchangeable or exercisable for, shares of Senior Securities; and 
 (iii) any increase or
decrease in the authorized number of shares of Series B Preferred Stock (except for the cancellation and retirement of shares set forth in Section 13(b) or as necessary for the payment of Series B Preferred Dividends in kind in
accordance with Section 4(a)) or the issuance of additional shares of Series B Preferred Stock (except for shares of Series B Preferred Stock issuable as payment of a Series B Preferred Dividend in accordance with Section 4).

 (c) In addition to any other vote required by applicable law, during any period (x) beginning (A) on
a Designated Milestone Redemption Date if the Corporation shall have failed to deposit on or prior to such Designated Milestone Redemption Date money in immediately available funds sufficient to pay the aggregate Milestone Redemption Price as of
such Designated Milestone Redemption Date for all shares of Series B Preferred Stock to be redeemed on such Designated Milestone Redemption Date or (B) at any time on or after a Designated Milestone Redemption Date that the Corporation
shall have failed to pay the applicable full Milestone Redemption Price for any share of Series B Preferred Stock to be redeemed on such Designated Milestone Redemption Date and ending at such time when the applicable full Milestone Redemption Price
for all shares of Series B Preferred Stock to be so redeemed shall have been paid to the Holders in cash (in each case, as set forth in Section 7 without giving effect to any qualifications or limitations as to “legal
availability” included therein and without regard to Section 7(b)(v)) or (y) beginning at any time that the Corporation shall have failed to pay the applicable full Change of Control Redemption Price for any share of
Series B Preferred Stock that a Holder of shares of Series B Preferred Stock has requested be redeemed and ending at such time when the full applicable Change of Control Redemption Price for all shares of Series B Preferred Stock so requested to be
redeemed shall have been paid to the Holders in cash (in each case, as set forth in Section 8 without giving effect to any qualifications or limitations as to “legal availability” included therein and without regard to
Section 8(b)(iii)), the Corporation shall not without the written consent, or affirmative vote at a meeting called for such purpose, by Holders representing at least a majority of the then issued and outstanding shares of Series B
Preferred Stock, voting together as a separate class: 
 (i) take any of, commit, resolve or agree to take any of, or authorize
or otherwise facilitate any of the actions set forth in Sections 6.1(a)(i)-(x) of the Stockholders Agreement (in each case, without giving effect to the qualification or limitation as to the “Investor Voting Interest” contained in
Section 6.1(a) of the Stockholders Agreement); 

  
 37 

 (ii) take any action that would result in an adjustment to the Conversion Price pursuant to
Section 10; 
 (iii) enter into any agreement or understanding, or commit, resolve or agree to enter into any
agreement or understanding with respect to a Business Combination; 
 (iv) hire, terminate or change the compensation of any
executive officer except for ordinary raises consistent with past practices (provided that, (A) the holders of the Series B Preferred Stock shall not unreasonably withhold or delay approval of any such hiring or termination, (B) if
the holders of Series B Preferred Stock shall not approve the hiring of any such executive officer the Corporation may appoint an existing employee to fill the position until a replacement approved by the holders of Series B Preferred
Stock is hired and (C) nothing herein shall prohibit the Corporation from terminating any executive officer for “cause” as defined in such executive officer’s employment agreement with the Corporation); or 

(v) adopt an annual budget (provided that if such consent or vote is not obtained, the budget for the Corporation for the immediately
prior year shall be utilized as the Corporation’s budget). 
 (d) Notwithstanding the foregoing, the Holders shall not have
any voting rights if, at or prior to the effective time of the act with respect to which such vote would otherwise be required, all outstanding shares of Series B Preferred Stock shall have been converted into shares of Common Stock or converted
into Exchange Property. 
 (e) The consent or votes required in Section 11(b) and Section 11(c) shall be
in addition to any approval of stockholders of the Corporation which may be required by law or pursuant to any provision of the Certificate of Incorporation or By-laws. 
 Section 12. Certificates. 
 (a) Transfer Agent. The duly appointed
Transfer Agent shall be the Corporation. The Corporation may, in its sole discretion, remove the Transfer Agent in accordance with the agreement between the Corporation and the Transfer Agent; provided that the Corporation shall appoint a
successor transfer agent of recognized standing who shall accept such appointment prior to the effectiveness of such removal. Upon any such removal or appointment, the Corporation shall send notice thereof by first-class mail, postage prepaid, to
the Holders. 
 (b) Form and Dating. The Series B Preferred Stock shall be initially issued and thereafter evidenced only in
definitive, certificated form. Each Preferred Stock certificate shall be dated the date of its authentication. 
 (c)
Execution and Authentication. Two Officers shall sign any Series B Preferred Stock certificate for the Corporation by manual or facsimile signature. If an Officer whose signature is on a Series B Preferred Stock certificate no longer holds
that office at the time the Transfer Agent authenticates the Series B Preferred Stock certificate, the Series B Preferred Stock certificate shall be valid nevertheless. A Series B Preferred Stock certificate shall not be valid until an authorized
signatory of the Transfer Agent manually signs the certificate of authentication on 

  
 38 

 
the Series B Preferred Stock certificate. The signature shall be conclusive evidence that such Series B Preferred Stock certificate has been authenticated under this Certificate. The Transfer
Agent shall authenticate and deliver certificates for shares of Preferred Stock for original issue upon a written order of the Corporation signed by two Officers of the Corporation or by an Officer and an Assistant Treasurer of the Corporation. Such
order shall specify the number of shares of Series B Preferred Stock to be authenticated and the date on which the original issue of Series B Preferred Stock is to be authenticated. The Transfer Agent may appoint an authenticating agent reasonably
acceptable to the Corporation to authenticate the certificates for Series B Preferred Stock. Unless limited by the terms of such appointment, an authenticating agent may authenticate certificates for Series B Preferred Stock whenever the Transfer
Agent may do so. Each reference in this Certificate to authentication by the Transfer Agent includes authentication by such agent. An authenticating agent has the same rights as the Transfer Agent or agent for service of notices and demands.

 (d) Transfer and Exchange. When (i) a Series B Preferred Stock certificate is presented to the Transfer Agent
with a request to register the transfer of such Series B Preferred Stock certificate or (ii) Series B Preferred Stock certificates are presented to the Transfer Agent with a request to exchange such Series B Preferred Stock certificates for a
Series B Preferred Stock certificate representing a number of shares of Series B Preferred Stock equal to the combined number of shares of Series B Preferred Stock represented by such presented certificates, the Transfer Agent shall register the
transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Series B Preferred Stock certificates surrendered for transfer or exchange: 

(i) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Corporation and the
Transfer Agent, duly executed by the holder thereof or its attorney duly authorized in writing; and 
 (ii) are being
transferred or exchanged in accordance with the Transfer Restrictions; and 
 (iii) if such Series B Preferred Stock
certificates are being delivered to the Transfer Agent by a Holder for registration in the name of such holder, without transfer, a certification from such holder to that effect. 

(e) Obligations with Respect to Transfers of Series B Preferred Stock. 

(i) To permit registrations of transfers and exchanges, the Corporation shall execute and the Transfer Agent shall authenticate Series B
Preferred Stock certificates as required pursuant to the provisions of this Section 11(e). 
 (ii) All Series B
Preferred Stock certificates issued upon any registration of transfer or exchange of Series B Preferred Stock certificates shall be the valid obligations of the Corporation, entitled to the same benefits under this Certificate as the Series B
Preferred Stock certificates surrendered upon such registration of transfer or exchange. 

  
 39 

 (iii) Prior to due presentment for registration of transfer of any shares of Series B
Preferred Stock, the Transfer Agent and the Corporation may deem and treat the Person in whose name such shares of Series B Preferred Stock are registered as the absolute owner of such Series B Preferred Stock and neither the Transfer Agent nor the
Corporation shall be affected by notice to the contrary. All notices and communications to be given to the Holders and all payments to be made to Holders under the Preferred Stock shall be given or made only to the Holders. 

(iv) The Transfer Agent shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on
transfer imposed under this Certificate or under applicable law with respect to any transfer of any interest in any Series B Preferred Stock other than to require delivery of such certificates and other documentation or evidence as are expressly
required by, and to do so if and when expressly required by, the terms of this Certificate, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 

(f) Replacement Certificates. If any Series B Preferred Stock certificate shall be mutilated, lost, stolen or destroyed, the
Corporation will issue, in exchange and in substitution for and upon cancellation of the mutilated certificate, or in lieu of and substitution for the certificate lost, stolen or destroyed, and the Transfer Agent shall countersign a replacement
Series B Preferred Stock certificate of like tenor and representing an equivalent amount of Series B Preferred Stock. If required by the Transfer Agent or the Corporation, such Holder shall furnish evidence of loss, theft or destruction of such
certificate and, if requested by the Corporation, an indemnity on customary terms for such situations reasonably satisfactory to the Corporation. 
 (g) Temporary Certificates. Until definitive Series B Preferred Stock certificates are ready for delivery, the Corporation may prepare and the Transfer Agent shall countersign temporary Series B
Preferred Stock certificates. Temporary Series B Preferred Stock certificates shall be substantially in the form of definitive Series B Preferred Stock certificates but may have variations that the Corporation considers appropriate for temporary
Series B Preferred Stock certificates. Without unreasonable delay, the Corporation shall prepare and the Transfer Agent shall countersign definitive Series B Preferred Stock certificates and deliver them in exchange for temporary Series B Preferred
Stock certificates. 
 (h) Cancellation. In the event the Corporation shall redeem or otherwise acquire Series B
Preferred Stock, the Series B Preferred Stock certificates representing such redeemed or acquired shares shall thereupon be delivered to the Transfer Agent for cancellation. 
 (i) Taxes. The issuance or delivery of shares of Series B Preferred Stock, shares of Common Stock or other securities issued on account of Series B Preferred Stock pursuant hereto, or certificates
representing such shares or securities, shall be made without charge to the Holder for such shares or certificates or for any tax in respect of the issuance or delivery of such certificates or the securities represented thereby, including, without
limitation, any share transfer, documentary, stamp or similar tax; provided, however, that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance or delivery of shares of Series B
Preferred Stock, shares of Common Stock or other securities in a name other than that in which the shares of Series B Preferred Stock with respect to which such shares or other securities were issued, delivered or registered, or in respect of any
payment to any Person 

  
 40 

 
other than a payment to the Holder thereof, and shall not be required to make any such issuance, delivery or payment unless and until the Person otherwise entitled to such issuance, delivery or
payment has paid to the Corporation the amount of any such tax or has established, to the satisfaction of the Corporation, that such tax has been paid or is not payable. 
 Section 13. Miscellaneous. 
 (a) Certain Covenants. 

(i) Without limiting the provisions of (or the Holders’ rights under) Section 8, Section 9 and
Section 11, the Corporation shall not merge with or into or consolidate with or into, or sell, transfer, exchange or lease all or substantially all of its property to, any other entity, or permit consummation of any other Business
Combination, unless the surviving successor, transferee or lessee entity, as the case may be (if not the Corporation), (x) expressly assumes, as part of the terms of such Business Combination, the due and punctual performance and
observance of each and every covenant and condition of this Certificate to be performed and observed by the Corporation and (y) if such Business Combination is a Qualified Business Combination, expressly agrees, as part of the terms of
such Qualified Business Combination, to exchange, at the Holders’ option, shares of Series B Preferred Stock for shares of the surviving entity’s capital stock having terms, preferences, rights (including, without limitation, as to
dividends, voting, redemption at the option of the Holder, and rights to assets upon liquidation, dissolution or winding-up of the entity), privileges and powers no less favorable (individually and in the aggregate) than the terms, preferences,
rights (including, without limitation, as to dividends, voting, redemption at the option of the Holder, and rights to assets upon liquidation, dissolution or winding-up of the entity), privileges and powers under this Certificate, in each case, such
that the rights of the Holders of Series B Preferred Stock are protected against dilution or other impairment. Without limiting any of the foregoing, the Corporation shall cause lawful provision to be made as part of the terms of each Business
Combination such that each Holder shares of Series B Preferred Stock then outstanding shall have the right after such Business Combination to exchange such shares for, or convert such shares into, the kind and amount of securities, cash and
other property receivable upon the Business Combination by a holder of Common Stock (that was not a counterparty to the Business Combination or an affiliate of such counterparty) holding that number of shares of Common Stock into which such shares
of Series B Preferred Stock would have been convertible (pursuant to Section 6 without regard to any limitations on convertibility therein) immediately prior to such Business Combination, and subject to anti-dilution adjustment
protections substantially equivalent to those set forth in this Certificate; provided, in the event that holders of shares of Common Stock have the opportunity to elect the form of consideration to be received in the Business Combination,
each Holder shall have the same opportunity to elect the form of consideration that each Holder is entitled to receive. 
 (ii)
The Corporation shall not, by amendment of the Certificate of Incorporation or through reorganization, consolidation, merger, dissolution, sale of assets, or otherwise, avoid or seek to avoid the observance or performance of any of the terms of this
Certificate, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holders of Series B Preferred Stock against
dilution or other impairment. 

  
 41 

 (iii) In addition to any other vote required by applicable law, the Corporation shall not,
without the consent of the Holders of a majority of the Series B Preferred Stock outstanding, enter into any debt agreement or other financing agreement which by its terms would restrict the payment of dividends pursuant to this Series B Certificate
or the payment of any amounts due upon the redemption of Series B Preferred Stock pursuant to Section 7 or Section 8. 
 (b) Status of Shares. Shares of Series B Preferred Stock which have been converted, redeemed, repurchased or otherwise cancelled shall be retired and, following the filing of any certificate
required by the DGCL, have the status of authorized and unissued shares of Preferred Stock, without designation as to series until such shares are once more, subject to and in accordance with the provisions of Section 11, designated as
part of a particular series of Preferred Stock by the Board of Directors. 
 (c) Notices. All notices referred to herein
shall be in writing, and, unless otherwise specified herein, all notices hereunder shall be deemed to have been given upon the earlier of receipt thereof or three Business Days after the mailing thereof if sent by registered or certified mail (or by

 General Terms and Conditions 

Base Contract for Sale and Purchase of Natural Gas 
 SECTION 1. PURPOSE AND PROCEDURES 
 1.1. These General Terms and Conditions are intended to
facilitate purchase and sale transactions of Gas on a Firm or Interruptible basis. “Buyer” refers to the party receiving Gas and “Seller” refers to the party delivering Gas. The entire agreement between the parties shall be the
Contract as defined in Section 2.9. 
  

	
	The parties have selected either the “Oral Transaction Procedure” or the “Written Transaction
Procedure” as indicated on the Base Contract.
	Oral Transaction Procedure:
	1.2. The parties will use the following Transaction Confirmation procedure. Any Gas purchase and sale
transaction may be effectuated in an EDI transmission or telephone conversation with the offer and acceptance constituting the agreement of the parties. The parties shall be legally bound from the time they so agree to transaction terms and may each
rely thereon. Any such transaction shall be considered a “writing” and to have been “signed”. Notwithstanding the foregoing sentence, the parties agree that Confirming Party shall, and the other party may, confirm a telephonic
transaction by sending the other party a Transaction Confirmation by facsimile, EDI or mutually agreeable electronic means within three Business Days of a transaction covered by this Section 1.2 (Oral Transaction Procedure) provided that the
failure to send a Transaction Confirmation shall not invalidate the oral agreement of the parties. Confirming Party adopts its confirming letterhead, or the like, as its signature on any Transaction Confirmation as the identification and
authentication of Confirming Party. If the Transaction Confirmation contains any provisions other than those relating to the commercial terms of the transaction (i.e., price, quantity, performance obligation, delivery point, period of delivery
and/or transportation conditions), which modify or supplement the Base Contract or General Terms and Conditions of this Contract (e.g., arbitration or additional representations and warranties), such provisions shall not be deemed to be accepted
pursuant to Section 1.3 but must be expressly agreed to by both parties; provided that the foregoing shall not invalidate any transaction agreed to by the parties.
	Written Transaction Procedure:
	1.2. The parties will use the following Transaction Confirmation procedure. Should the parties come to an
agreement regarding a Gas purchase and sale transaction for a particular Delivery Period, the Confirming Party shall, and the other party may, record that agreement on a Transaction Confirmation and communicate such Transaction Confirmation by
facsimile, EDI or mutually agreeable electronic means, to the other party by the close of the Business Day following the date of agreement. The parties acknowledge that their agreement will not be binding until the exchange of nonconflicting
Transaction Confirmations or the passage of the Confirm Deadline without objection from the receiving party, as provided in Section 1.3.

 1.3. If a sending party’s Transaction Confirmation is materially different from the receiving party’s
understanding of the agreement referred to in Section 1.2, such receiving party shall notify the sending party via facsimile, EDI or mutually agreeable electronic means by the Confirm Deadline, unless such receiving party has previously sent a
Transaction Confirmation to the sending party. The failure of the receiving party to so notify the sending party in writing by the Confirm Deadline constitutes the receiving party’s agreement to the terms of the transaction described in the
sending party’s Transaction Confirmation. If there are any material differences between timely sent Transaction Confirmations governing the same transaction, then neither Transaction Confirmation shall be binding until or unless such
differences are resolved including the use of any evidence that clearly resolves the differences in the Transaction Confirmations. In the event of a conflict among the terms of (i) a binding Transaction Confirmation pursuant to
Section 1.2, (ii) the oral agreement of the parties which may be evidenced by a recorded conversation, where the parties have selected the Oral Transaction Procedure of the Base Contract, (iii) the Base Contract, and (iv) these
General Terms and Conditions, the terms of the documents shall govern in the priority listed in this sentence. 
 1.4. The parties agree that
each party may electronically record all telephone conversations with respect to this Contract between their respective employees, without any special or further notice to the other party. Each party shall obtain any necessary consent of its agents
and employees to such recording. Where the parties have selected the Oral Transaction Procedure in Section 1.2 of the Base Contract, the parties agree not to contest the validity or enforceability of telephonic recordings entered into in
accordance with the requirements of this Base Contract. 
 SECTION 2. DEFINITIONS 
 The terms set forth below shall have the meaning ascribed to them below. Other terms are also defined elsewhere in the Contract and shall have the meanings ascribed to them herein. 

2.1. “Additional Event of Default” shall mean Transactional Cross Default or Indebtedness Cross Default, each as and if selected by the parties
pursuant to the Base Contract. 
 2.2. “Affiliate” shall mean, in relation to any person, any entity controlled, directly or
indirectly, by the person, any entity that controls, directly or indirectly, the person or any entity directly or indirectly under common control with the person. For this purpose, “control” of any entity or person means ownership of at
least 50 percent of the voting power of the entity or person.

 2.3. “Alternative Damages” shall mean such damages, expressed in dollars or dollars per MMBtu, as
the parties shall agree upon in the Transaction Confirmation, in the event either Seller or Buyer fails to perform a Firm obligation to deliver Gas in the case of Seller or to receive Gas in the case of Buyer. 

2.4. “Base Contract” shall mean a contract executed by the parties that incorporates these General Terms and Conditions by reference; that
specifies the agreed selections of provisions contained herein; and that sets forth other information required herein and any Special Provisions and addendum(s) as identified on page one.

4.3. The parties shall use commercially reasonable efforts to avoid imposition of any Imbalance Charges. If Buyer or Seller receives an invoice from a
Transporter that includes Imbalance Charges, the parties shall determine the validity as well as the cause of such Imbalance Charges. If the Imbalance Charges were incurred as a result of Buyer’s receipt of quantities of Gas greater than or
less than the Scheduled Gas, then Buyer shall pay for such Imbalance Charges or reimburse Seller for such Imbalance Charges paid by Seller. If the Imbalance Charges were incurred as a result of Seller’s delivery of quantities of Gas greater
than or less than the Scheduled Gas, then Seller shall pay for such Imbalance Charges or reimburse Buyer for such Imbalance Charges paid by Buyer.

a party is required to remit or pay Taxes that are the other party’s responsibility hereunder, the party responsible for such Taxes shall promptly reimburse the other party for such Taxes. Any party entitled to an exemption from any such Taxes
or charges shall furnish the other party any necessary documentation thereof.

 7.2. Buyer shall remit the amount due under Section 7.1 in the manner specified in the Base Contract,
in immediately available funds, on or before the later of the Payment Date or 10 Days after receipt of the invoice by Buyer; provided that if the Payment Date is not a Business Day, payment is due on the next Business Day following that date. In the
event any payments are due Buyer hereunder, payment to Buyer shall be made in accordance with this Section 7.2. 
 7.3. In the event
payments become due pursuant to Sections 3.2 or 3.3, the performing party may submit an invoice to the nonperforming party for an accelerated payment setting forth the basis upon which the invoiced amount was calculated. Payment from the
nonperforming party will be due five Business Days after receipt of invoice. 
 7.4. If the invoiced party, in good faith, disputes the amount
of any such invoice or any part thereof, such invoiced party will pay such amount as it concedes to be correct; provided, however, if the invoiced party disputes the amount due, it must provide supporting documentation acceptable in industry
practice to support the amount paid or disputed without undue delay. In the event the parties are unable to resolve such dispute, either party may pursue any remedy available at law or in equity to enforce its rights pursuant to this Section.

 7.5. If the invoiced party fails to remit the full amount payable when due, interest on the unpaid portion shall accrue from the date due

This right to examine, audit, and to obtain copies shall not be available with respect to proprietary information not directly relevant to transactions under this Contract. All invoices and billings shall be conclusively presumed final and accurate
and all associated claims for under- or overpayments shall be deemed waived unless such invoices or billings are objected to in writing, with adequate explanation and/or documentation, within two years after the Month of Gas delivery. All
retroactive adjustments under Section 7 shall be paid in full by the party owing payment within 30 Days of Notice and substantiation of such inaccuracy. 
 7.7. Unless the parties have elected on the Base Contract not to make this Section 7.7 applicable to this Contract, the parties shall net all undisputed amounts due and owing, and/or past due,
arising under the Contract such that the party owing the greater amount shall make a single payment of the net amount to the other party in accordance with Section 7; provided that no payment required to be made pursuant to the terms of any
Credit Support Obligation or pursuant to Section 7.3 shall be subject to netting under this Section. If the parties have executed a separate netting agreement, the terms and conditions therein shall prevail to the extent inconsistent herewith.

passes to Buyer. Buyer agrees to indemnify Seller and save it harmless from all Claims, from any and all persons, arising from or out of claims regarding payment, personal injury (including death) or property damage from said Gas or other charges
thereon which attach after title passes to Buyer. 
 8.4. The parties agree that the delivery of and the transfer of title to all Gas under this
Contract shall take place within the Customs Territory of the United States (as defined in general note 2 of the Harmonized Tariff Schedule of the United States 19 U.S.C. §1202, General Notes, page 3); provided, however, that in the event
Seller took title to the Gas outside the Customs Territory of the United States, Seller represents and warrants that it is the importer of record for all Gas entered and delivered into the United States, and shall be responsible for entry and entry
summary filings as well as the payment of duties, taxes and fees, if any, and all applicable record keeping requirements. 
 8.5.
Notwithstanding the other provisions of this Section 8, as between Seller and Buyer, Seller will be liable for all Claims to the extent that such arise from the failure of Gas delivered by Seller to meet the quality requirements of
Section 5.

Date”) for the liquidation and termination pursuant to Section 10.3.1 of all transactions under the Contract, each a “Terminated Transaction”. On the Early Termination Date, all transactions will terminate, other than those
transactions, if any, that may not be liquidated and terminated under applicable law (“Excluded Transactions”), which Excluded Transactions must be liquidated and terminated as soon thereafter as is legally permissible, and upon
termination shall be a Terminated Transaction and be valued consistent with Section 10.3.1 below. With respect to each Excluded Transaction, its actual termination date shall be the Early Termination Date for purposes of Section 10.3.1.

  

	
	The parties have selected either “Early Termination Damages Apply” or “Early Termination
Damages Do Not Apply” as indicated on the Base Contract.
	Early Termination Damages Apply:
	 10.3.1. As of the Early Termination Date, the
Non-Defaulting Party shall determine, in good faith and in a commercially reasonable manner, (i) the amount owed (whether or not then due) by each party with respect to all Gas delivered and received between the parties under Terminated
Transactions and Excluded Transactions on and before the Early Termination Date and all other applicable charges relating to such deliveries and receipts (including without limitation any amounts owed under Section 3.2), for which payment has
not yet been made by the party that owes such payment under this Contract and (ii) the Market Value, as defined below, of each Terminated Transaction. The Non-Defaulting Party shall (x) liquidate and accelerate each Terminated Transaction
at its Market Value, so that each amount equal to the difference between such Market Value and the Contract Value, as defined below, of such Terminated Transaction(s) shall be due to the Buyer under the Terminated Transaction(s) if such Market Value
exceeds the Contract Value and to the Seller if the opposite is the case; and (y) where appropriate, discount each amount then due under clause (x) above to present value in a commercially reasonable manner as of the Early Termination Date
(to take account of the period between the date of liquidation and the date on which such amount would have otherwise been due pursuant to the relevant Terminated Transactions).

 
 For purposes of this Section 10.3.1, “Contract Value” means the
amount of Gas remaining to be delivered or purchased under a transaction multiplied by the Contract Price, and “Market Value” means the amount of Gas remaining to be delivered or purchased under a transaction multiplied by the market price
for a similar transaction at the Delivery Point determined by the Non-Defaulting Party in a commercially reasonable manner. To ascertain the Market Value, the Non-Defaulting Party may consider, among other valuations, any or all of the settlement
prices of NYMEX Gas futures contracts, quotations from leading dealers in energy swap contracts or physical gas trading markets, similar sales or purchases and any other bona fide third-party offers, all adjusted for the length of the term and
differences in transportation costs. A party shall not be required to enter into a replacement transaction(s) in order to determine the Market Value. Any extension(s) of the term of a transaction to which parties are not bound as of the Early
Termination Date (including but not limited to “evergreen provisions”) shall not be considered in determining Contract Values and

	Market Values. For the avoidance of doubt, any option pursuant to which one party has the right to extend the
term of a transaction shall be considered in determining Contract Values and Market Values. The rate of interest used in calculating net present value shall be determined by the Non-Defaulting Party in a commercially reasonable
manner.
	Early Termination Damages Do Not Apply:
	 10.3.1. As of the Early Termination Date, the Non-Defaulting Party shall
determine, in good faith and in a commercially reasonable manner, the amount owed (whether or not then due) by each party with respect to all Gas delivered and received between the parties under Terminated Transactions and Excluded Transactions on
and before the Early Termination Date and all other applicable charges relating to such deliveries and receipts (including without limitation any amounts owed under Section 3.2), for which payment has not yet been made by the party that owes
such payment under this Contract.

	 10.3.2. The Non-Defaulting Party shall net or aggregate, as appropriate, any and
all amounts owing between the parties under Section 10.3.1, so that all such amounts are netted or aggregated to a single liquidated amount payable by one party to the other (the “Net Settlement Amount”). At its sole option and
without prior Notice to the Defaulting Party, the Non-Defaulting Party may setoff any Net Settlement Amount against any margin or other collateral held by a party in connection with any Credit Support Obligation relating to the
Contract.

 10.3.3. If any obligation that is to be included in any netting, aggregation or setoff pursuant to
Section 10.3.2 is unascertained, the Non-Defaulting Party may in good faith estimate that obligation and net, aggregate or setoff, as applicable, in respect of the estimate, subject to the Non-Defaulting Party accounting to the Defaulting Party
when the obligation is ascertained. Any amount not then due which is included in any netting, aggregation or setoff pursuant to Section 10.3.2 shall be discounted to net present value in a commercially reasonable manner determined by the
Non-Defaulting Party. 
 10.4. As soon as practicable after a liquidation, Notice shall be given by the Non-Defaulting Party to the Defaulting
Party of the Net Settlement Amount, and whether the Net Settlement Amount is due to or due from the Non-Defaulting Party. The Notice shall include a written statement explaining in reasonable detail the calculation of the Net Settlement Amount,
provided that failure to give such Notice shall not affect the validity or enforceability of the liquidation or give rise to any claim by the Defaulting Party against the Non-Defaulting Party. The Net Settlement Amount as well as any setoffs applied
against such amount pursuant to Section 10.3.2, shall be paid by the close of business on the second Business Day following such Notice, which date shall not be earlier than the Early Termination Date. Interest on any unpaid portion of the Net
Settlement Amount as adjusted by setoffs, shall accrue from the date due until the date of payment at a rate equal to the lower of (i) the then-effective prime rate of interest published under “Money Rates” by The Wall Street Journal,
plus two percent per annum; or (ii) the maximum applicable lawful interest rate. 
 10.5. The parties agree that the transactions hereunder
constitute a “forward contract” within the meaning of the United States Bankruptcy Code and that Buyer and Seller are each “forward contract merchants” within the meaning of the United States Bankruptcy Code. 

10.6. The Non-Defaulting Party’s remedies under this Section 10 are the sole and exclusive remedies of the Non-Defaulting Party with respect to
the occurrence of any Early Termination Date. Each party reserves to itself all other rights, setoffs, counterclaims and other defenses that it is or may be entitled to arising from the Contract.

 10.7. With respect to this Section 10, if the parties have executed a separate netting agreement with
close-out netting provisions, the terms and conditions therein shall prevail to the extent inconsistent herewith. 
 SECTION 11. FORCE
MAJEURE 
 11.1. Except with regard to a party’s obligation to make payment(s) due under Section 7, Section 10.4, and Imbalance
Charges under Section 4, neither party shall be liable to the other for failure to perform a Firm obligation, to the extent such failure was caused by Force Majeure. The term “Force Majeure” as employed herein means any cause not
reasonably within the control of the party claiming suspension, as further defined in Section 11.2. 
 11.2. Force Majeure shall include,
but not be limited to, the following: (i) physical events such as acts of God, landslides, lightning, earthquakes, fires, storms or storm warnings, such as hurricanes, which result in evacuation of the affected area, floods, washouts,
explosions, breakage or accident or necessity of repairs to machinery or equipment or lines of pipe; (ii) weather related events affecting an entire geographic region, such as low temperatures which cause freezing or failure of wells or lines
of pipe; (iii) interruption and/or curtailment of Firm transportation and/or storage by Transporters; (iv) acts of others such as strikes, lockouts or other industrial disturbances, riots, sabotage, insurrections or wars, or acts of
terror; and (v) governmental actions such as necessity for compliance with any court order, law, statute, ordinance, regulation, or policy having the effect of law promulgated by a governmental authority having jurisdiction. Seller and Buyer
shall make reasonable efforts to avoid the adverse impacts of a Force Majeure and to resolve the event or occurrence once it has occurred in order to resume performance. 
 11.3. Neither party shall be entitled to the benefit of the provisions of Force Majeure to the extent performance is affected by any or all of the following circumstances: (i) the curtailment of
interruptible or secondary Firm transportation unless primary, in-path, Firm transportation is also curtailed; (ii) the party claiming excuse failed to remedy the condition and to resume the performance of such covenants or obligations with
reasonable dispatch; or (iii) economic hardship, to include, without limitation, Seller’s ability to sell Gas at a higher or more advantageous price than the Contract Price, Buyer’s ability to purchase Gas at a lower or more
advantageous price than the Contract Price, or a regulatory agency disallowing, in whole or in part, the pass through of costs resulting from this Contract; (iv) the loss of Buyer’s market(s) or Buyer’s inability to use or resell Gas
purchased hereunder, except, in either case, as provided in Section 11.2; or (v) the loss or failure of Seller’s gas supply or depletion of reserves, except, in either case, as provided in Section 11.2. The party claiming Force
Majeure shall not be excused from its responsibility for Imbalance Charges. 
 11.4. Notwithstanding anything to the contrary herein, the
parties agree that the settlement of strikes, lockouts or other industrial disturbances shall be within the sole discretion of the party experiencing such disturbance. 
 11.5. The party whose performance is prevented by Force Majeure must provide Notice to the other party. Initial Notice may be given orally; however, written Notice with reasonably full particulars of the
event or occurrence is required as soon as reasonably possible. Upon providing written Notice of Force Majeure to the other party, the affected party will be relieved of its obligation, from the onset of the Force Majeure event, to make or accept
delivery of Gas, as applicable, to the extent and for the duration of Force Majeure, and neither party shall be deemed to have failed in such obligations to the other during such occurrence or event. 

11.6. Notwithstanding Sections 11.2 and 11.3, the parties may agree to alternative Force Majeure provisions in a Transaction Confirmation executed in
writing by both parties. 
 SECTION 12. TERM 
 This Contract may be terminated on 30 Day’s written Notice, but shall remain in effect until the expiration of the latest Delivery Period of any transaction(s). The rights of either party pursuant to
Section 7.6, Section 10, Section 13, the obligations to make payment hereunder, and the obligation of either party to indemnify the other, pursuant hereto shall survive the termination of the Base Contract or any transaction.

 SECTION 13. LIMITATIONS 
 FOR
BREACH OF ANY PROVISION FOR WHICH AN EXPRESS REMEDY OR MEASURE OF DAMAGES IS PROVIDED, SUCH EXPRESS REMEDY OR MEASURE OF DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY. A PARTY’S LIABILITY HEREUNDER SHALL BE LIMITED AS SET FORTH IN SUCH
PROVISION, AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. IF NO REMEDY OR MEASURE OF DAMAGES IS EXPRESSLY PROVIDED HEREIN OR IN A TRANSACTION, A PARTY’S LIABILITY SHALL BE LIMITED TO DIRECT ACTUAL DAMAGES ONLY. SUCH DIRECT
ACTUAL DAMAGES SHALL BE THE SOLE AND EXCLUSIVE REMEDY, AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. UNLESS EXPRESSLY HEREIN PROVIDED, NEITHER PARTY SHALL BE LIABLE FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR INDIRECT
DAMAGES, LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES, BY STATUTE, IN TORT OR CONTRACT, UNDER ANY INDEMNITY PROVISION OR OTHERWISE. IT IS THE INTENT OF THE PARTIES THAT THE LIMITATIONS HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF DAMAGES BE
WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO, INCLUDING THE NEGLIGENCE OF ANY PARTY, WHETHER SUCH NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, OR ACTIVE OR PASSIVE. TO THE EXTENT ANY DAMAGES REQUIRED TO BE PAID HEREUNDER ARE LIQUIDATED, THE
PARTIES ACKNOWLEDGE THAT THE DAMAGES ARE DIFFICULT OR IMPOSSIBLE TO DETERMINE, OR OTHERWISE OBTAINING AN ADEQUATE REMEDY IS INCONVENIENT AND THE DAMAGES CALCULATED HEREUNDER CONSTITUTE A REASONABLE APPROXIMATION OF THE HARM OR LOSS.

 SECTION 14. MARKET DISRUPTION 
 If a Market Disruption Event has occurred then the parties shall negotiate in good faith to agree on a replacement price for the Floating Price (or on a method for determining a replacement price for the
Floating Price) for the affected Day, and if the parties have not so agreed on or before the second Business Day following the affected Day then the replacement price for the Floating Price shall be determined within the next two following Business
Days with each party obtaining, in good faith and from non-affiliated market participants in the relevant market, two quotes for prices of Gas for the affected Day of a similar quality and quantity in the geographical location closest in proximity
to the Delivery Point and averaging the four quotes. If either party fails to provide two quotes then the average of the other party’s two quotes shall determine the replacement price for the Floating Price. “Floating Price” means the
price or a factor of the price agreed to in the transaction as being based upon a specified index. “Market Disruption Event” means, with respect to an index specified for a transaction, any of the following events: (a) the failure of
the index to announce or publish information necessary for determining the Floating Price; (b) the failure of trading to commence or the permanent discontinuation or material suspension of trading on the exchange or market acting as the index;
(c) the temporary or permanent discontinuance or unavailability of the index; (d) the temporary or permanent closing of any exchange acting as the index; or (e) both parties agree that a material change in the formula for or the
method of determining the Floating Price has occurred. For the purposes of the calculation of a replacement price for the Floating Price, all numbers shall be rounded to three decimal places. If the fourth decimal number is five or greater, then the
third decimal number shall be increased by one and if the fourth decimal number is less than five, then the third decimal number shall remain unchanged. 
 SECTION 15. MISCELLANEOUS 
 15.1. This Contract shall be binding upon and inure to the benefit
of the successors, assigns, personal representatives, and heirs of the respective parties hereto, and the covenants, conditions, rights and obligations of this Contract shall run for the full term of this Contract. No assignment of this Contract, in
whole or in part, will be made without the prior written consent of the non-assigning party (and shall not relieve the assigning party from liability hereunder), which consent will not be unreasonably withheld or delayed; provided, either party may
(i) transfer, sell, pledge, encumber, or assign this Contract or the accounts, revenues, or proceeds hereof in connection with any financing or other financial arrangements, or (ii) transfer its interest to any parent or Affiliate by
assignment, merger or otherwise without the prior approval of the other party. Upon any such assignment, transfer and assumption, the transferor shall remain principally liable for and shall not be relieved of or discharged from any obligations
hereunder. 
 15.2. If any provision in this Contract is determined to be invalid, void or unenforceable by any court having jurisdiction, such
determination shall not invalidate, void, or make unenforceable any other provision, agreement or covenant of this Contract. 
 15.3. No waiver
of any breach of this Contract shall be held to be a waiver of any other or subsequent breach. 
 15.4. This Contract sets forth all
understandings between the parties respecting each transaction subject hereto, and any prior contracts, understandings and representations, whether oral or written, relating to such transactions are merged into and superseded by this Contract and
any effective transaction(s). This Contract may be amended only by a writing executed by both parties. 
 15.5. The interpretation and
performance of this Contract shall be governed by the laws of the jurisdiction as indicated on the Base Contract, excluding, however, any conflict of laws rule which would apply the law of another jurisdiction. 

15.6. This Contract and all provisions herein will be subject to all applicable and valid statutes, rules, orders and regulations of any governmental
authority having jurisdiction over the parties, their facilities, or Gas supply, this Contract or transaction or any provisions thereof. 

15.7. There is no third party beneficiary to this Contract. 
 15.8. Each party to this Contract represents and warrants that it has full and complete authority to enter into and perform this Contract. Each person who executes this Contract on behalf of either party
represents and warrants that it has full and complete authority to do so and that such party will be bound thereby. 
 15.9. The headings and
subheadings contained in this Contract are used solely for convenience and do not constitute a part of this Contract between the parties and shall not be used to construe or interpret the provisions of this Contract. 

15.10. Unless the parties have elected on the Base Contract not to make this Section 15.10 applicable to this Contract, neither party shall disclose
directly or indirectly without the prior written consent of the other party the terms of any transaction to a third party (other than the employees, lenders, royalty owners, counsel, accountants and other agents of the party, or prospective
purchasers of all or substantially all of a party’s assets or of any rights under this Contract, provided such persons shall have agreed to keep such terms confidential) except (i) in order to comply with any applicable law, order,
regulation, or exchange rule, (ii) to the extent necessary for the enforcement of this Contract , (iii) to the extent necessary to implement any transaction, (iv) to the extent necessary to comply with a regulatory agency’s
reporting requirements including but not limited to gas cost recovery proceedings; or (v) to the extent such information is delivered to such third party for the sole purpose of calculating a published index. Each party shall notify the other
party of any proceeding of which it is aware which may result in disclosure of the terms of any transaction (other than as permitted hereunder) and use reasonable efforts to prevent or limit the disclosure. The existence of this Contract is not
subject to this confidentiality obligation. Subject to Section 13, the parties shall be entitled to all remedies available at law or in equity to enforce, or seek relief in connection with this confidentiality obligation. The terms of any
transaction hereunder shall be kept confidential by the parties hereto for one year from the expiration of the transaction.

evidence.
