Warrant Shares have been duly authorized and reserved for issuance upon exercise of the Warrants, and upon such exercise in accordance with the terms thereof, will be validly issued, fully paid and non-assessable, free from all taxes, liens and
charges except those created by the Warrantholders, and will not be subject to preemptive rights or other similar rights of any holders of Common Stock or other interests of the Company. Assuming the accuracy of the representations and warranties of
the Warrantholders in Section 3.04 and Section 3.05 hereof, the offer and issuance by the Company of the Warrant is exempt from the registration requirements of Section 5 of the Securities Act of 1933, as amended (the

Activity. Anything in this Agreement or elsewhere herein to the contrary notwithstanding, but subject to compliance by the Warrantholder with applicable law, it is understood and acknowledged by the Company (i) that the Warrantholder has
not been asked by the Company or its Subsidiaries to agree, and the Warrantholder has not agreed with the Company or its Subsidiaries, to desist from purchasing or selling, long and/or short, securities of the Company, or “derivative”
securities based on securities issued by the Company or to hold the Warrant for any specified term except as set forth in the “standstill” provision of that certain Confidentiality Agreement, dated June 3, 2011, between the Company
and Highbridge Principal Strategies, LLC (the “Confidentiality Agreement”) which provision the Company hereby irrevocably waives (it being understood that the Warrantholder remains subject to all other terms and provisions of the
Confidentiality Agreement in accordance with its terms); (ii) that past or future open market or other transactions by the Warrantholder, including, without limitation, short sales or “derivative” transactions, before or after the

counter-party in any “derivative” transaction. The Company further understands and acknowledges that (a) the Warrantholder may engage in hedging and/or trading activities at various times during the period that the Warrants are
outstanding, including, without limitation, during the periods that the value of the Warrant Shares deliverable with respect to Warrants are being determined and (b) such hedging and/or trading activities (if any) could reduce the value of the
existing stockholders’ equity interests in the Company at and after the time that the hedging and/or trading activities are being conducted. Notwithstanding the foregoing, the Warrantholder shall not be permitted to engage in short sales or
transfer its Warrants or Warrant Shares (other than to its affiliates) from the date hereof until the date that is ninety (90) days following the date hereof.

 BUILDERS FIRSTSOURCE, INC. 
 WARRANT TO PURCHASE COMMON STOCK 
 Warrant No.:________ 
 Number of Shares of Common Stock: _______________

 Date of Issuance: December 2, 2011 (“Issuance Date”) 

Builders FirstSource, Inc., a Delaware corporation (the “Company”), hereby certifies
that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [HIGHBRIDGE HOLDERS], the registered holder hereof or its permitted assigns (the “Holder”), is entitled, subject to the terms
set forth below, to purchase from the Company, at the Exercise Price (as defined below) then in effect, at any time or times on or after the Issuance Date (the “Initial Exercisability Date”), but not after 11:59 p.m., New York time,
on the Expiration Date, (as defined below), ______________ (            )1 fully paid nonassessable shares of Common Stock, par value $0.01 per share, subject to adjustment as provided herein
(the “Warrant Shares”). Except as otherwise defined herein, capitalized terms in this Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, this
“Warrant”) shall have the meanings set forth in Section 19. This Warrant is one of the Warrants to Purchase Common Stock (the “Issuance Warrants”) being issued pursuant to Section 1.01 of that certain
Warrant Issuance Agreement, dated as of December 2, 2011 (the “Issuance Agreement”), by and among the Company and each of the warrantholders that are signatories thereto. 

 
  

	1 	 The aggregate number of shares of Common Stock to be issued to the Holders shall be equal to 1,600,000 shares. 

 1. EXERCISE OF WARRANT. 

(a) Mechanics of Exercise. Subject to the terms and conditions hereof (including, without
limitation, the limitations set forth in Section 1(f)), this Warrant may be exercised by the Holder on any time or times on or after the Initial Exercisability Date, in whole or in part, by (i) delivery of a written notice, in the form
attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant, together with (ii) (A) payment to the Company of an amount equal to the applicable Exercise Price multiplied
by the number of Warrant Shares as to which this Warrant is being exercised (the “Aggregate Exercise Price”) in cash by wire transfer of immediately available funds or (B) a written notice to the Company that this Warrant is
being exercised pursuant to a Cashless Exercise (as defined in Section 1(d)) (the date on which the Holder has complied with clauses (i) and (ii) of this Section 1(a), the “Exercise Notice Date”). The Holder
shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the
original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. On or before the third (3rd) Trading Day following the Exercise Notice Date (the “Share Delivery Date”), the Company shall
(X) provided that the Company’s transfer agent (the “Transfer Agent”) is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program and the Warrant Shares to be
received by the Holder upon such exercise are freely transferable, upon the request of the Holder, credit such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s
balance account with DTC through its Deposit / Withdrawal At Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program or if the Warrant Shares to be received by the Holder upon
such exercise are not freely transferable, issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the
number of Warrant Shares to which the Holder is entitled pursuant to such exercise. The Company shall be responsible for all fees and expenses of the Transfer Agent and all fees and expenses with respect to the issuance of Warrant Shares via DTC, if
any. On the Exercise Notice Date, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date such Warrant Shares are
credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be. If this Warrant is submitted together with the Exercise Notice pursuant to this Section 1(a) and the
number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares with respect to which the Holder exercises this Warrant, then the Company shall as soon as practicable and in no event later
than three (3) Trading Days after any exercise and at its own expense, issue a new Warrant (in accordance with Section 8(d)) representing the right to purchase the number of Warrant Shares issuable immediately prior to such exercise under
this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the Company, at its option, shall deliver cash in
lieu of fractional shares or issue the number of shares of Common Stock rounded up to the nearest whole number. The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of
this 

  
 2 

 
Warrant, provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer of any certificates for Warrant Shares or Warrants
in a name other than that of the Holder or any tax imposed under Section 897 or Section 1445 of the Internal Revenue Code of 1986, as amended. The Company and the Holder shall act reasonably in good faith to minimize the amount of such
taxes, if any. 
 (b) Exercise Price. For purposes of this Warrant, “Exercise Price”
means $2.50, subject to adjustment as provided herein. 
 (c) Company’s Failure to Timely Deliver
Securities. If on or before the Share Delivery Date the Company shall fail to issue and dispatch a certificate to the Holder and register such shares of Common Stock on the Company’s share register or credit the Holder’s balance
account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise hereunder or pursuant to the Company’s obligation pursuant to clause (ii) below, and if after such Share Delivery
Date the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the
Company (a “Buy-In”), then the Company shall, within three (3) Trading Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s
total purchase price (including brokerage commissions and other reasonable out-of-pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to issue and
dispatch such certificate representing such shares of Common Stock or credit such Holder’s balance account with DTC shall terminate, or (ii) promptly honor its obligation to issue and dispatch to the Holder a certificate or certificates
representing such shares of Common Stock or credit such Holder’s balance account with DTC and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common
Stock, times (B) the Weighted Average Price of Common Stock on the Exercise Notice Date. Nothing shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity, including, without limitation, a
decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock (or to electronically deliver such shares of Common Stock) upon the exercise of
this Warrant as required pursuant to the terms hereof. 
 (d) Cashless Exercise. Notwithstanding
anything contained herein to the contrary, the Holder may exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise
Price, elect instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”): 

  
 3 

 
			
	Net Number =	    	 (A x B) - (A x C)

		    	 B

		    	

 For purposes of the foregoing formula: 

A= the total number of shares with respect to which this Warrant is then being exercised. 

B= the Weighted Average Price of the Common Stock for the Exercise Notice Date. 

C= the Exercise Price in effect for the applicable Exercise Notice Date. 

If “Net Number” is negative, “Net Number” shall be deemed to be zero. 

For purposes of Rule 144(d) promulgated under the Securities Act, as in effect on the date hereof, it is intended that
the Warrant Shares issued in a Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued to such Holder by
the Company pursuant to the Issuance Agreement. 
 (e) Disputes. In the case of a dispute as to the
determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 13.

 (f) Limitations on Exercises. The Company shall not effect the exercise of this Warrant, and the
Holder shall not have the right to exercise this Warrant, to the extent that after giving effect to such exercise, such Person (together with such Person’s affiliates) would beneficially own in excess of 4.99% (the “Maximum
Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Person and its
affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon
(i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Person and its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company
beneficially owned by such Person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants), in each case, subject to a limitation on conversion or exercise analogous to the limitation
contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”). For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s

  
 4 

 
most recent Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission (“SEC”), as the case may be, (2) a more
recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written request of the Holder, the Company shall within one
(1) Business Day confirm in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of
securities of the Company, including the Issuance Warrants, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the Holder may from time to
time increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company, and
(ii) any such increase or decrease will apply only to the Holder and not to any other holder of the Issuance Warrants. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the
terms of this Section 1(f) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to
properly give effect to such limitation. 
 (g) Insufficient Authorized Shares. If at any time while
this Warrant remains outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of this Warrant at least a number of shares of Common
Stock equal to 100% of the number of shares of Common Stock (the “Required Reserve Amount”) as shall from time to time be necessary to effect the exercise of all of this Warrant then outstanding (an “Authorized Share
Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for this
Warrant then outstanding. 
 (h) Issue Price. The parties hereto (i) acknowledge and agree that,
for U.S. federal income tax purposes, (A) the Loan (as that term is defined in the Financing Agreement) and the Issuance Warrants constitute an “investment unit” and (B) the issue price of the Loan is $153,600,000 and the issue
price of the Warrant is $1,600,000; and (ii) unless otherwise required by applicable law, shall not take any position contrary to the preceding clause (i) for U.S. federal income tax and all other purposes. 

2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares
shall be adjusted from time to time as follows: 
 (a) Adjustment Upon Issuance of Shares of Common
Stock. If and whenever on or after the Issuance Date, the Company issues or sells, or in accordance with this Section 2 is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock
owned or held by or for the account of the Company, but excluding the issuance or sale, or deemed issuance or sale, of any Excluded Securities) for a consideration per share less than a price (the “Applicable Price”) equal to the
Exercise Price in 

  
 5 

 
effect immediately prior to such issue or sale or deemed issuance or sale (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance, the Exercise Price
then in effect shall be reduced to an amount equal to the product of (A) the Exercise Price in effect immediately prior to such Dilutive Issuance and (B) the quotient determined by dividing (1) the sum of (I) the product derived
by multiplying the Exercise Price in effect immediately prior to such Dilutive Issuance and the number of shares of Common Stock Deemed Outstanding immediately prior to such Dilutive Issuance plus (II) the consideration, if any, received by the
Company upon such Dilutive Issuance, by (2) the product derived by multiplying (I) the Exercise Price in effect immediately prior to such Dilutive Issuance by (II) the number of shares of Common Stock Deemed Outstanding immediately
after such Dilutive Issuance. Upon each such adjustment of the Exercise Price hereunder, the number of Warrant Shares issuable immediately prior to such Dilutive Issuance shall be adjusted to the number of shares of Common Stock determined by
multiplying the Exercise Price then in effect immediately prior to such adjustment by the number of Warrant Shares acquirable upon exercise of this Warrant immediately prior to such adjustment and dividing the product thereof by the Exercise Price
resulting from such adjustment. For purposes of determining the adjusted Exercise Price under this Section 2(a), the following shall be applicable: 

(i) Issuance of Options. If the Company in any manner grants any Options and the lowest price per
share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable Price, then such
share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 2(a)(i), the “lowest price
per share for which one share of Common Stock is issuable upon exercise of such Options or upon conversion, exercise or exchange of such Convertible Securities issuable upon exercise of any such Option” shall be equal to the sum of the lowest
amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of the Option, upon exercise of the Option and upon conversion, exercise or exchange of any Convertible
Security issuable upon exercise of such Option less any consideration paid or payable by the Company with respect to such one share of Common Stock upon the granting or sale of such Option, upon exercise of such Option and upon conversion exercise
or exchange of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common Stock or of such Convertible
Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities. 

(ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any
Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be
outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this 

  
 6 

 
Section 2(a)(ii), the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof” shall be equal to the sum of the
lowest amounts of consideration (if any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security
less any consideration paid or payable by the Company with respect to such one share of Common Stock upon the issuance or sale of such Convertible Security and upon conversion, exercise or exchange of such Convertible Security. No further adjustment
of the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or sale of such Convertible
Securities is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made pursuant to other provisions of this Section 2(a), no further adjustment of the Exercise Price or number of Warrant Shares shall be
made by reason of such issue or sale. 
 (iii) Change in Option Price or Rate of
Conversion. If the purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are
convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the Exercise Price and the number of Warrant Shares in effect at the time of such increase or decrease shall be adjusted to the Exercise
Price and the number of Warrant Shares which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion
rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 2(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are increased or
decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of
the date of such increase or decrease. No adjustment pursuant to this Section 2(a) shall be made if such adjustment would result in an increase of the Exercise Price then in effect or a decrease in the number of Warrant Shares. 

(iv) Calculation of Consideration Received. In case any Option is issued in connection with the
issue or sale of other securities of the Company, together comprising one integrated transaction, (x) the Options will be deemed to have been issued for the Option Value of such Options and (y) the other securities issued or sold in such
integrated transaction shall be deemed to have been issued for the difference of (I) the aggregate consideration received by the Company less any consideration paid or payable by the Company pursuant to the terms of such other securities of the
Company, less (II) the Option Value. If any shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received
by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration 

  
 7 

 
received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company
will be the Closing Sale Price of such security on the date of receipt. If any shares of Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the
surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible
Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the Required Holders. If such parties are unable to reach agreement within ten (10) days after the
occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Trading Days after the tenth
(10th) day following the Valuation Event by an
independent, reputable appraiser jointly selected by the Company and the Required Holders. The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be
borne by the Company. 
 (v) Record Date. If the Company takes a record of the holders of
shares of Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase shares of Common Stock,
Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or purchase, as the case may be. 
 (b)
Voluntary Adjustment By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

 (c) Adjustment Upon Subdivision or Combination of shares of Common Stock. If the Company at any time
on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately
prior to such subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Issuance Date combines (by combination, reverse stock split or otherwise) one or
more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares will be proportionately
decreased. Any adjustment under this Section 2(c) shall become effective at the close of business on the date the subdivision or combination becomes effective. 

 

  
 8 

 (d) Other Events. If any event occurs of the type contemplated by
the provisions of this Section 2 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features, but excluding the issuance
or deemed issuance by the Company of any Excluded Securities), then the Company’s Board of Directors will make an appropriate adjustment in the Exercise Price and the number of Warrant Shares so as to protect the rights of the Holder;
provided that no such adjustment pursuant to this Section 2(d) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this Section 2. The good faith determination of the
Company’s Board of Directors with respect to such adjustment shall be conclusive and binding upon the Holders. 
 3. RIGHTS UPON DISTRIBUTION OF ASSETS. If the Company at any time on or after the Issuance Date sets a record date or takes a record of the holders of its Common Stock for the purpose of any
dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities (other
than Common Stock), property or options by way of a dividend, spin off or other similar transaction), then, (1) the number of shares of Common Stock for which this Warrant is exercisable shall be adjusted to equal the product of the number of
shares of Common Stock for which this Warrant is exercisable immediately prior to such adjustment (without giving effect to the limitations on exercise set forth in Section 1(f) hereof) multiplied by a fraction (A) the numerator of which
shall be the Weighted Average Price of Common Stock at the date of taking such record and (B) the denominator of which shall be such Weighted Average Price minus the amount allocable to one share of Common Stock of any such cash so
distributable and of the fair value (as determined in good faith by the Board of Directors of the Company) of any and all such evidences of indebtedness, shares of stock, other securities or property or warrants or other subscription or purchase
rights so distributable, and (2) the Exercise Price then in effect shall be adjusted to equal (A) the Exercise Price then in effect multiplied by the number of shares of Common Stock for which this Warrant is exercisable immediately prior
to the adjustment (without giving effect to the limitations on exercise set forth in Section 1(f) hereof) divided by (B) the number of shares of Common Stock for which this Warrant is exercisable immediately after such adjustment (without
giving effect to the limitations on exercise set forth in Section 1(f) hereof). Any adjustment under this Section 2(c) shall become effective at the close of business on the date the distribution that triggered the adjustment becomes
effective. 
 4. PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS. 

(a) Purchase Rights. In lieu of any adjustments pursuant to Section 2 above, if at any time the Company
grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), then the Holder
will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this
Warrant (without regard to any limitations on exercise hereof, including without limitation, the Maximum Percentage) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such
record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, that to the

  
 9 

 
extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in
such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever,
as its right thereto would not result in the Holder exceeding the Maximum Percentage, at which time the Holder shall be granted such right to the same extent as if there had been no such limitation). 

(b) Fundamental Transactions. (i) Prior to the consummation of any Fundamental Transaction pursuant to which
holders of shares of Common Stock are entitled to receive securities, the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive, upon an exercise of this Warrant at any time after the
consummation of such Fundamental Transaction but prior to the Expiration Date, in lieu of the Warrant Shares issuable upon the exercise of this Warrant prior to such Fundamental Transaction, such securities as the Holder would have been entitled to
receive upon the occurrence of such Fundamental Transaction had this Warrant been exercised immediately prior to such Fundamental Transaction. The provisions of this Section 4(b)(i) shall be applied without regard to any limitations on the
exercise of this Warrant set forth in Section 1(f). 
 (ii) Upon the consummation of any
Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive cash or other property or assets (other than securities) with respect to, or in exchange for, shares of Common Stock, the Holder will receive, in
lieu of the Warrant Shares issuable upon the exercise of this Warrant prior to such Fundamental Transaction, such cash, assets or other property whatsoever (other than securities) as the Holder would have been entitled to receive upon the occurrence
of such Fundamental Transaction had this Warrant been exercised through Cashless Exercise immediately prior to such Fundamental Transaction 
 5. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation or Bylaws, or through any reorganization, transfer of
assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good
faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. For the avoidance of doubt, (a) in the event that the Company, directly or indirectly, engages in any reorganization,
transfer of assets, consolidation, merger, scheme of arrangement, dissolution or similar transactions and (b) such transaction is not a Fundamental Transaction, the Person formed by, resulting from or surviving such transaction or the Person
with which such transaction shall have been entered into, in each case only to the extent such Person is not the Company (the “Successor Entity”), shall assume in writing all of the obligations of the Company under this Warrant and
shall deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant. Without limiting the generality of the foregoing, the Company
(i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the
Company may validly and legally issue fully 

  
 10 

 
paid and nonassessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as any of the Issuance Warrants are outstanding, take all action necessary to
reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of the Issuance Warrants, 100% of the number of shares of Common Stock as shall from time to time be necessary to
effect the exercise of the Issuance Warrants then outstanding (without regard to any limitations on exercise). 

6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely
in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to
confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue
of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which such Person is
then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as
a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. 
 7. INFORMATION RIGHTS. Notwithstanding Section 6 hereof, the Company shall provide the Holder with copies of the same notices and other information given to the stockholders of the Company
generally, contemporaneously with the giving thereof, and in the same manner as the Company customarily provides such information, to such stockholders. 
 8. REISSUANCE OF WARRANTS. 
 (a) Transfer of
Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 8(d)),
registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less than the total number of Warrant Shares then underlying all such Holder’s Warrants is being
transferred (which number of transferred Warrant Shares by such Holder and its affiliates to the transferee and its affiliates may not be less than 100,000 shares (the “Minimum Transfer Amount”); provided, that such
restriction shall not apply to transfers by the Holder to any of its affiliates, and, for purposes of determining whether the Minimum Transfer Amount is satisfied, all transfers by a Holder and its affiliates to a transferee and its affiliates shall
be aggregated), a new Warrant (in accordance with Section 8(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred (which number of Warrant Shares may not be less than the Minimum Transfer
Amount). The Minimum Transfer Amount shall be subject to the same adjustments as the number of Warrant Shares pursuant to Section 2. Without the prior written consent of the Company, no Holder may transfer any Warrant if, as a result of such
transfer, the aggregate number of outstanding Warrants would be held of record by more than eight (8) Persons (treating, for purposes of this calculation, Persons that are “Affiliates,” as that term is defined in Rule 405 promulgated
under the Securities Act, as a single Person). 
  

  
 11 

 (b) Lost, Stolen or Mutilated Warrant. Upon receipt by the Company
of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and,
in the case of mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 8(d)) representing the right to purchase the Warrant Shares then
underlying this Warrant. 
 (c) Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon
the surrender hereof by the Holder at the principal office of the Company, for a new Warrant or Warrants (in accordance with Section 8(d)) representing in the aggregate the right to purchase the number of Warrant Shares then underlying this
Warrant, and each such new Warrant will represent the right to purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, that no Issuance Warrants for fractional
shares of Common Stock shall be given. 
 (d) Issuance of New Warrants. Whenever the Company is required
to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then
underlying this Warrant (or in the case of a new Warrant being issued pursuant to Section 8(a) or Section 8(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new
Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance
Date, and (iv) shall have the same rights and conditions as this Warrant. 
 9. NOTICES. Whenever
notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given by first class mail prepaid at such Holder’s address as it appears on the books of the Company, as furnished by such Holder to the
Company from time to time, receipt of such notice to be confirmed by such Holder by electronic transmission to the Company at ______________. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this
Warrant, including in reasonable detail a description of such action and the reason therefor. Without limiting the generality of the foregoing, any Exercise Notice to be delivered to the Company by a Holder pursuant to Section 1(a) hereof
(together with any written notice required to be delivered pursuant to Section 1(a)(ii)(B)) will be delivered by such Holder both by first class mail prepaid or overnight delivery to the Company at 2001 Bryan Street, Suite 1600, Dallas Texas
75201, Attn.: General Counsel, and by electronic transmission to the Company at ___________. In addition, without limiting the generality of the foregoing, the Company will give written notice to the Holder (i) promptly upon any adjustment of
the Exercise Price, setting forth in reasonable detail, and certifying, the calculation of such adjustment and (ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes a record (A) with respect
to any dividend or 

  
 12 

 
distribution upon the shares of Common Stock, (B) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities or
other property to holders of shares of Common Stock or (C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation; provided in each case that such information shall be made known to the
public prior to or in conjunction with such notice being provided to the Holder. 
 10. AMENDMENT AND
WAIVER. Except as otherwise provided herein, the provisions of this Warrant may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained
the written consent of the Holder. 
 11. GOVERNING LAW. This Warrant shall be governed by and construed
and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or
conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. The Company hereby irrevocably submits to the
exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein,
and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or
that the venue of such suit, action or proceeding is improper. The Company hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at
the address it set forth on the signature page hereto and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in
any manner permitted by law. Nothing contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Company in any other jurisdiction to collect on the Company’s obligations to the
Holder, to realize on any collateral or any other security for such obligations, or to enforce a judgment or other court ruling in favor of the Holder. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY
TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY. 
 12. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and all the Buyers and shall not be construed against any person as the drafter hereof. The headings of

 13. DISPUTE RESOLUTION. In the case of a dispute as to the
determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within two (2) Business Days of receipt of the Exercise
Notice giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three (3) Business Days of such
disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) Business Days submit via facsimile (a) the disputed determination of the Exercise Price to an independent, reputable
investment bank selected by the Company and approved by the Holder or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The Company shall cause at its expense the investment
bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than ten (10) Business Days from the time it receives the disputed determinations or
calculations. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error. 

14. REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant shall be
cumulative and in addition to all other remedies available under this Warrant and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the
right of the Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the
remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction
restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 
 15. LEGENDS.

 Except as otherwise permitted by this Section 15, each certificate for Common Stock (or
Other Securities) issued upon the exercise of any Warrant, and each certificate issued upon the transfer of any such Common Stock, shall be stamped or otherwise imprinted with a legend in substantially the following form: 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS

(b) Termination of Restrictions. The restrictions imposed on the transferability of securities set forth in the
legend of this Warrant shall cease and terminate as to any particular securities (i) when a registration statement with respect to the sale of such securities shall have been declared effective under the Securities Act and such securities shall
have been disposed of in accordance with such registration statement, (ii) when such securities are sold pursuant to Rule 144 or Rule 144A (or any similar provision then in force) under the Securities Act, or (iii) when such restrictions
are no longer required or necessary in order to protect the Company against a violation of the Securities Act upon any sale or other disposition of such securities without registration thereunder. Whenever such restrictions shall cease and terminate
as to any such Securities, the holder thereof shall be entitled to receive from the Company, without expense, new securities of like tenor not bearing the legend set forth in this Warrant. 

(c) Subject to compliance with Sections 15(a) and 15(b), if applicable, this Warrant, the Warrant Shares

 (d) The Company acknowledges and agrees that the Warrants and the Warrant Shares may be pledged by the Holder in connection with a bona fide margin agreement or other loan or financing arrangement that is
secured by such securities. The pledge of the Warrant or the Warrant Shares shall not be deemed to be a transfer, sale or assignment of such securities hereunder, and no Holder effecting a pledge of such securities shall be required to

  
 15 

 
provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement. The Company hereby agrees, subject to applicable securities laws, to execute
and deliver such documentation as a pledgee of such securities may reasonably request in connection with a pledge of such securities to such pledgee by a Holder.

(b) For the avoidance of doubt, this Warrant shall not limit the Company’s right to delist, deregister, or
otherwise effect any Fundamental Transaction 
 17. SEVERABILITY. If any provision of this Warrant is
prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it
would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material change,
the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of
the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid
provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

 Warrant No.:________ 
 Number of Shares of Common Stock: _______________ 
 Date of Issuance:
December 2, 2011 (“Issuance Date”) 
 Builders FirstSource, Inc., a
Delaware corporation (the “Company”), hereby certifies that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [HIGHBRIDGE HOLDERS], the registered holder hereof or its permitted
assigns (the “Holder”), is entitled, subject to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined below) then in effect, at any time or times on or after the Issuance Date (the
“Initial Exercisability Date”), but not after 11:59 p.m., New York time, on the Expiration Date, (as defined below), ______________ (            )1 fully paid nonassessable shares of Common Stock, par value $0.01 per
share, subject to adjustment as provided herein (the “Warrant Shares”). Except as otherwise defined herein, capitalized terms in this Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in
exchange, transfer or replacement hereof, this “Warrant”) shall have the meanings set forth in Section 19. This Warrant is one of the Warrants to Purchase Common Stock (the “Issuance Warrants”) being issued
pursuant to Section 1.01 of that certain Warrant Issuance Agreement, dated as of December 2, 2011 (the “Issuance Agreement”), by and among the Company and each of the warrantholders that are signatories thereto.

  
  

	1 	 The aggregate number of shares of Common Stock to be issued to the Holders shall be equal to 1,600,000 shares. 

 1. EXERCISE OF WARRANT. 

(a) Mechanics of Exercise. Subject to the terms and conditions hereof (including, without
limitation, the limitations set forth in Section 1(f)), this Warrant may be exercised by the Holder on any time or times on or after the Initial Exercisability Date, in whole or in part, by (i) delivery of a written notice, in the form
attached hereto as Exhibit A (the “Exercise Notice”), of the Holder’s election to exercise this Warrant, together with (ii) (A) payment to the Company of an amount equal to the applicable Exercise Price multiplied
by the number of Warrant Shares as to which this Warrant is being exercised (the “Aggregate Exercise Price”) in cash by wire transfer of immediately available funds or (B) a written notice to the Company that this Warrant is
being exercised pursuant to a Cashless Exercise (as defined in Section 1(d)) (the date on which the Holder has complied with clauses (i) and (ii) of this Section 1(a), the “Exercise Notice Date”). The Holder
shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice with respect to less than all of the Warrant Shares shall have the same effect as cancellation of the
original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining number of Warrant Shares. On or before the third (3rd) Trading Day following the Exercise Notice Date (the “Share Delivery Date”), the Company shall
(X) provided that the Company’s transfer agent (the “Transfer Agent”) is participating in The Depository Trust Company (“DTC”) Fast Automated Securities Transfer Program and the Warrant Shares to be
received by the Holder upon such exercise are freely transferable, upon the request of the Holder, credit such aggregate number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s
balance account with DTC through its Deposit / Withdrawal At Custodian system, or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program or if the Warrant Shares to be received by the Holder upon
such exercise are not freely transferable, issue and dispatch by overnight courier to the address as specified in the Exercise Notice, a certificate, registered in the Company’s share register in the name of the Holder or its designee, for the
number of Warrant Shares to which the Holder is entitled pursuant to such exercise. The Company shall be responsible for all fees and expenses of the Transfer Agent and all fees and expenses with respect to the issuance of Warrant Shares via DTC, if
any. On the Exercise Notice Date, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date such Warrant Shares are
credited to the Holder’s DTC account or the date of delivery of the certificates evidencing such Warrant Shares, as the case may be. If this Warrant is submitted together with the Exercise Notice pursuant to this Section 1(a) and the
number of Warrant Shares represented by this Warrant submitted for exercise is greater than the number of Warrant Shares with respect to which the Holder exercises this Warrant, then the Company shall as soon as practicable and in no event later
than three (3) Trading Days after any exercise and at its own expense, issue a new Warrant (in accordance with Section 8(d)) representing the right to purchase the number of Warrant Shares issuable immediately prior to such exercise under
this Warrant, less the number of Warrant Shares with respect to which this Warrant is exercised. No fractional shares of Common Stock are to be issued upon the exercise of this Warrant, but rather the Company, at its option, shall deliver cash in
lieu of fractional shares or issue the number of shares of Common Stock rounded up to the nearest whole number. The Company shall pay any and all taxes which may be payable with respect to the issuance and delivery of Warrant Shares upon exercise of
this 

  
 2 

 
Warrant, provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer of any certificates for Warrant Shares or Warrants
in a name other than that of the Holder or any tax imposed under Section 897 or Section 1445 of the Internal Revenue Code of 1986, as amended. The Company and the Holder shall act reasonably in good faith to minimize the amount of such
taxes, if any. 
 (b) Exercise Price. For purposes of this Warrant, “Exercise Price”
means $2.50, subject to adjustment as provided herein. 
 (c) Company’s Failure to Timely Deliver
Securities. If on or before the Share Delivery Date the Company shall fail to issue and dispatch a certificate to the Holder and register such shares of Common Stock on the Company’s share register or credit the Holder’s balance
account with DTC for the number of shares of Common Stock to which the Holder is entitled upon the Holder’s exercise hereunder or pursuant to the Company’s obligation pursuant to clause (ii) below, and if after such Share Delivery
Date the Holder purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the Holder anticipated receiving from the
Company (a “Buy-In”), then the Company shall, within three (3) Trading Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s
total purchase price (including brokerage commissions and other reasonable out-of-pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to issue and
dispatch such certificate representing such shares of Common Stock or credit such Holder’s balance account with DTC shall terminate, or (ii) promptly honor its obligation to issue and dispatch to the Holder a certificate or certificates
representing such shares of Common Stock or credit such Holder’s balance account with DTC and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common
Stock, times (B) the Weighted Average Price of Common Stock on the Exercise Notice Date. Nothing shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity, including, without limitation, a
decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock (or to electronically deliver such shares of Common Stock) upon the exercise of
this Warrant as required pursuant to the terms hereof. 
 (d) Cashless Exercise. Notwithstanding
anything contained herein to the contrary, the Holder may exercise this Warrant in whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise in payment of the Aggregate Exercise
Price, elect instead to receive upon such exercise the “Net Number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”): 

  
 3 

 
			
	Net Number =	    	 (A x B) - (A x C)

		    	 B

		    	

 For purposes of the foregoing formula: 

A= the total number of shares with respect to which this Warrant is then being exercised. 

B= the Weighted Average Price of the Common Stock for the Exercise Notice Date. 

C= the Exercise Price in effect for the applicable Exercise Notice Date. 

If “Net Number” is negative, “Net Number” shall be deemed to be zero. 

For purposes of Rule 144(d) promulgated under the Securities Act, as in effect on the date hereof, it is intended that
the Warrant Shares issued in a Cashless Exercise shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued to such Holder by
the Company pursuant to the Issuance Agreement. 
 (e) Disputes. In the case of a dispute as to the
determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed and resolve such dispute in accordance with Section 13.

 (f) Limitations on Exercises. The Company shall not effect the exercise of this Warrant, and the
Holder shall not have the right to exercise this Warrant, to the extent that after giving effect to such exercise, such Person (together with such Person’s affiliates) would beneficially own in excess of 4.99% (the “Maximum
Percentage”) of the shares of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by such Person and its
affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common Stock which would be issuable upon
(i) exercise of the remaining, unexercised portion of this Warrant beneficially owned by such Person and its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company
beneficially owned by such Person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants), in each case, subject to a limitation on conversion or exercise analogous to the limitation
contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”). For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s

  
 4 

 
most recent Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission (“SEC”), as the case may be, (2) a more
recent public announcement by the Company or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written request of the Holder, the Company shall within one
(1) Business Day confirm in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of
securities of the Company, including the Issuance Warrants, by the Holder and its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. By written notice to the Company, the Holder may from time to
time increase or decrease the Maximum Percentage to any other percentage not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be effective until the sixty-first (61st) day after such notice is delivered to the Company, and
(ii) any such increase or decrease will apply only to the Holder and not to any other holder of the Issuance Warrants. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the
terms of this Section 1(f) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to
properly give effect to such limitation. 
 (g) Insufficient Authorized Shares. If at any time while
this Warrant remains outstanding the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligation to reserve for issuance upon exercise of this Warrant at least a number of shares of Common
Stock equal to 100% of the number of shares of Common Stock (the “Required Reserve Amount”) as shall from time to time be necessary to effect the exercise of all of this Warrant then outstanding (an “Authorized Share
Failure”), then the Company shall immediately take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve the Required Reserve Amount for this
Warrant then outstanding. 
 (h) Issue Price. The parties hereto (i) acknowledge and agree that,
for U.S. federal income tax purposes, (A) the Loan (as that term is defined in the Financing Agreement) and the Issuance Warrants constitute an “investment unit” and (B) the issue price of the Loan is $153,600,000 and the issue
price of the Warrant is $1,600,000; and (ii) unless otherwise required by applicable law, shall not take any position contrary to the preceding clause (i) for U.S. federal income tax and all other purposes. 

2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES. The Exercise Price and the number of Warrant Shares
shall be adjusted from time to time as follows: 
 (a) Adjustment Upon Issuance of Shares of Common
Stock. If and whenever on or after the Issuance Date, the Company issues or sells, or in accordance with this Section 2 is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock
owned or held by or for the account of the Company, but excluding the issuance or sale, or deemed issuance or sale, of any Excluded Securities) for a consideration per share less than a price (the “Applicable Price”) equal to the
Exercise Price in 

  
 5 

 
effect immediately prior to such issue or sale or deemed issuance or sale (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance, the Exercise Price
then in effect shall be reduced to an amount equal to the product of (A) the Exercise Price in effect immediately prior to such Dilutive Issuance and (B) the quotient determined by dividing (1) the sum of (I) the product derived
by multiplying the Exercise Price in effect immediately prior to such Dilutive Issuance and the number of shares of Common Stock Deemed Outstanding immediately prior to such Dilutive Issuance plus (II) the consideration, if any, received by the
Company upon such Dilutive Issuance, by (2) the product derived by multiplying (I) the Exercise Price in effect immediately prior to such Dilutive Issuance by (II) the number of shares of Common Stock Deemed Outstanding immediately
after such Dilutive Issuance. Upon each such adjustment of the Exercise Price hereunder, the number of Warrant Shares issuable immediately prior to such Dilutive Issuance shall be adjusted to the number of shares of Common Stock determined by
multiplying the Exercise Price then in effect immediately prior to such adjustment by the number of Warrant Shares acquirable upon exercise of this Warrant immediately prior to such adjustment and dividing the product thereof by the Exercise Price
resulting from such adjustment. For purposes of determining the adjusted Exercise Price under this Section 2(a), the following shall be applicable: 

(i) Issuance of Options. If the Company in any manner grants any Options and the lowest price per
share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable Price, then such
share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such Option for such price per share. For purposes of this Section 2(a)(i), the “lowest price
per share for which one share of Common Stock is issuable upon exercise of such Options or upon conversion, exercise or exchange of such Convertible Securities issuable upon exercise of any such Option” shall be equal to the sum of the lowest
amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting or sale of the Option, upon exercise of the Option and upon conversion, exercise or exchange of any Convertible
Security issuable upon exercise of such Option less any consideration paid or payable by the Company with respect to such one share of Common Stock upon the granting or sale of such Option, upon exercise of such Option and upon conversion exercise
or exchange of any Convertible Security issuable upon exercise of such Option. No further adjustment of the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common Stock or of such Convertible
Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities. 

(ii) Issuance of Convertible Securities. If the Company in any manner issues or sells any
Convertible Securities and the lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less than the Applicable Price, then such share of Common Stock shall be deemed to be
outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes of this 

  
 6 

 
Section 2(a)(ii), the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof” shall be equal to the sum of the
lowest amounts of consideration (if any) received or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security
less any consideration paid or payable by the Company with respect to such one share of Common Stock upon the issuance or sale of such Convertible Security and upon conversion, exercise or exchange of such Convertible Security. No further adjustment
of the Exercise Price or number of Warrant Shares shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or sale of such Convertible
Securities is made upon exercise of any Options for which adjustment of this Warrant has been or is to be made pursuant to other provisions of this Section 2(a), no further adjustment of the Exercise Price or number of Warrant Shares shall be
made by reason of such issue or sale. 
 (iii) Change in Option Price or Rate of
Conversion. If the purchase price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are
convertible into or exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the Exercise Price and the number of Warrant Shares in effect at the time of such increase or decrease shall be adjusted to the Exercise
Price and the number of Warrant Shares which would have been in effect at such time had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion
rate, as the case may be, at the time initially granted, issued or sold. For purposes of this Section 2(a)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of this Warrant are increased or
decreased in the manner described in the immediately preceding sentence, then such Option or Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of
the date of such increase or decrease. No adjustment pursuant to this Section 2(a) shall be made if such adjustment would result in an increase of the Exercise Price then in effect or a decrease in the number of Warrant Shares. 

(iv) Calculation of Consideration Received. In case any Option is issued in connection with the
issue or sale of other securities of the Company, together comprising one integrated transaction, (x) the Options will be deemed to have been issued for the Option Value of such Options and (y) the other securities issued or sold in such
integrated transaction shall be deemed to have been issued for the difference of (I) the aggregate consideration received by the Company less any consideration paid or payable by the Company pursuant to the terms of such other securities of the
Company, less (II) the Option Value. If any shares of Common Stock, Options or Convertible Securities are issued or sold or deemed to have been issued or sold for cash, the consideration received therefor will be deemed to be the net amount received
by the Company therefor. If any shares of Common Stock, Options or Convertible Securities are issued or sold for a consideration other than cash, the amount of such consideration 

  
 7 

 
received by the Company will be the fair value of such consideration, except where such consideration consists of securities, in which case the amount of consideration received by the Company
will be the Closing Sale Price of such security on the date of receipt. If any shares of Common Stock, Options or Convertible Securities are issued to the owners of the non-surviving entity in connection with any merger in which the Company is the
surviving entity, the amount of consideration therefor will be deemed to be the fair value of such portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible
Securities, as the case may be. The fair value of any consideration other than cash or securities will be determined jointly by the Company and the Required Holders. If such parties are unable to reach agreement within ten (10) days after the
occurrence of an event requiring valuation (the “Valuation Event”), the fair value of such consideration will be determined within five (5) Trading Days after the tenth
(10th) day following the Valuation Event by an
independent, reputable appraiser jointly selected by the Company and the Required Holders. The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be
borne by the Company. 
 (v) Record Date. If the Company takes a record of the holders of
shares of Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in shares of Common Stock, Options or in Convertible Securities or (B) to subscribe for or purchase shares of Common Stock,
Options or Convertible Securities, then such record date will be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other
distribution or the date of the granting of such right of subscription or purchase, as the case may be. 
 (b)
Voluntary Adjustment By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

 (c) Adjustment Upon Subdivision or Combination of shares of Common Stock. If the Company at any time
on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately
prior to such subdivision will be proportionately reduced and the number of Warrant Shares will be proportionately increased. If the Company at any time on or after the Issuance Date combines (by combination, reverse stock split or otherwise) one or
more classes of its outstanding shares of Common Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such combination will be proportionately increased and the number of Warrant Shares will be proportionately
decreased. Any adjustment under this Section 2(c) shall become effective at the close of business on the date the subdivision or combination becomes effective. 

 

  
 8 

 (d) Other Events. If any event occurs of the type contemplated by
the provisions of this Section 2 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features, but excluding the issuance
or deemed issuance by the Company of any Excluded Securities), then the Company’s Board of Directors will make an appropriate adjustment in the Exercise Price and the number of Warrant Shares so as to protect the rights of the Holder;
provided that no such adjustment pursuant to this Section 2(d) will increase the Exercise Price or decrease the number of Warrant Shares as otherwise determined pursuant to this Section 2. The good faith determination of the
Company’s Board of Directors with respect to such adjustment shall be conclusive and binding upon the Holders. 
 3. RIGHTS UPON DISTRIBUTION OF ASSETS. If the Company at any time on or after the Issuance Date sets a record date or takes a record of the holders of its Common Stock for the purpose of any
dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities (other
than Common Stock), property or options by way of a dividend, spin off or other similar transaction), then, (1) the number of shares of Common Stock for which this Warrant is exercisable shall be adjusted to equal the product of the number of
shares of Common Stock for which this Warrant is exercisable immediately prior to such adjustment (without giving effect to the limitations on exercise set forth in Section 1(f) hereof) multiplied by a fraction (A) the numerator of which
shall be the Weighted Average Price of Common Stock at the date of taking such record and (B) the denominator of which shall be such Weighted Average Price minus the amount allocable to one share of Common Stock of any such cash so
distributable and of the fair value (as determined in good faith by the Board of Directors of the Company) of any and all such evidences of indebtedness, shares of stock, other securities or property or warrants or other subscription or purchase
rights so distributable, and (2) the Exercise Price then in effect shall be adjusted to equal (A) the Exercise Price then in effect multiplied by the number of shares of Common Stock for which this Warrant is exercisable immediately prior
to the adjustment (without giving effect to the limitations on exercise set forth in Section 1(f) hereof) divided by (B) the number of shares of Common Stock for which this Warrant is exercisable immediately after such adjustment (without
giving effect to the limitations on exercise set forth in Section 1(f) hereof). Any adjustment under this Section 2(c) shall become effective at the close of business on the date the distribution that triggered the adjustment becomes
effective. 
 4. PURCHASE RIGHTS; FUNDAMENTAL TRANSACTIONS. 

(a) Purchase Rights. In lieu of any adjustments pursuant to Section 2 above, if at any time the Company
grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), then the Holder
will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this
Warrant (without regard to any limitations on exercise hereof, including without limitation, the Maximum Percentage) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such
record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, that to the

  
 9 

 
extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in
such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever,
as its right thereto would not result in the Holder exceeding the Maximum Percentage, at which time the Holder shall be granted such right to the same extent as if there had been no such limitation). 

(b) Fundamental Transactions. (i) Prior to the consummation of any Fundamental Transaction pursuant to which
holders of shares of Common Stock are entitled to receive securities, the Company shall make appropriate provision to insure that the Holder will thereafter have the right to receive, upon an exercise of this Warrant at any time after the
consummation of such Fundamental Transaction but prior to the Expiration Date, in lieu of the Warrant Shares issuable upon the exercise of this Warrant prior to such Fundamental Transaction, such securities as the Holder would have been entitled to
receive upon the occurrence of such Fundamental Transaction had this Warrant been exercised immediately prior to such Fundamental Transaction. The provisions of this Section 4(b)(i) shall be applied without regard to any limitations on the
exercise of this Warrant set forth in Section 1(f). 
 (ii) Upon the consummation of any
Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive cash or other property or assets (other than securities) with respect to, or in exchange for, shares of Common Stock, the Holder will receive, in
lieu of the Warrant Shares issuable upon the exercise of this Warrant prior to such Fundamental Transaction, such cash, assets or other property whatsoever (other than securities) as the Holder would have been entitled to receive upon the occurrence
of such Fundamental Transaction had this Warrant been exercised through Cashless Exercise immediately prior to such Fundamental Transaction 
 5. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation or Bylaws, or through any reorganization, transfer of
assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and will at all times in good
faith carry out all the provisions of this Warrant and take all action as may be required to protect the rights of the Holder. For the avoidance of doubt, (a) in the event that the Company, directly or indirectly, engages in any reorganization,
transfer of assets, consolidation, merger, scheme of arrangement, dissolution or similar transactions and (b) such transaction is not a Fundamental Transaction, the Person formed by, resulting from or surviving such transaction or the Person
with which such transaction shall have been entered into, in each case only to the extent such Person is not the Company (the “Successor Entity”), shall assume in writing all of the obligations of the Company under this Warrant and
shall deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant. Without limiting the generality of the foregoing, the Company
(i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such actions as may be necessary or appropriate in order that the
Company may validly and legally issue fully 

  
 10 

 
paid and nonassessable shares of Common Stock upon the exercise of this Warrant, and (iii) shall, so long as any of the Issuance Warrants are outstanding, take all action necessary to
reserve and keep available out of its authorized and unissued shares of Common Stock, solely for the purpose of effecting the exercise of the Issuance Warrants, 100% of the number of shares of Common Stock as shall from time to time be necessary to
effect the exercise of the Issuance Warrants then outstanding (without regard to any limitations on exercise). 

6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER. Except as otherwise specifically provided herein, the Holder, solely
in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to
confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue
of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which such Person is
then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as
a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company. 
 7. INFORMATION RIGHTS. Notwithstanding Section 6 hereof, the Company shall provide the Holder with copies of the same notices and other information given to the stockholders of the Company
generally, contemporaneously with the giving thereof, and in the same manner as the Company customarily provides such information, to such stockholders. 
 8. REISSUANCE OF WARRANTS. 
 (a) Transfer of
Warrant. If this Warrant is to be transferred, the Holder shall surrender this Warrant to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 8(d)),
registered as the Holder may request, representing the right to purchase the number of Warrant Shares being transferred by the Holder and, if less than the total number of Warrant Shares then underlying all such Holder’s Warrants is being
transferred (which number of transferred Warrant Shares by such Holder and its affiliates to the transferee and its affiliates may not be less than 100,000 shares (the “Minimum Transfer Amount”); provided, that such
restriction shall not apply to transfers by the Holder to any of its affiliates, and, for purposes of determining whether the Minimum Transfer Amount is satisfied, all transfers by a Holder and its affiliates to a transferee and its affiliates shall
be aggregated), a new Warrant (in accordance with Section 8(d)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred (which number of Warrant Shares may not be less than the Minimum Transfer
Amount). The Minimum Transfer Amount shall be subject to the same adjustments as the number of Warrant Shares pursuant to Section 2. Without the prior written consent of the Company, no Holder may transfer any Warrant if, as a result of such
transfer, the aggregate number of outstanding Warrants would be held of record by more than eight (8) Persons (treating, for purposes of this calculation, Persons that are “Affiliates,” as that term is defined in Rule 405 promulgated
under the Securities Act, as a single Person). 
  

  
 11 

 (b) Lost, Stolen or Mutilated Warrant. Upon receipt by the Company
of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and,
in the case of mutilation, upon surrender and cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in accordance with Section 8(d)) representing the right to purchase the Warrant Shares then
underlying this Warrant. 
 (c) Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon
the surrender hereof by the Holder at the principal office of the Company, for a new Warrant or Warrants (in accordance with Section 8(d)) representing in the aggregate the right to purchase the number of Warrant Shares then underlying this
Warrant, and each such new Warrant will represent the right to purchase such portion of such Warrant Shares as is designated by the Holder at the time of such surrender; provided, however, that no Issuance Warrants for fractional
shares of Common Stock shall be given. 
 (d) Issuance of New Warrants. Whenever the Company is required
to issue a new Warrant pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then
underlying this Warrant (or in the case of a new Warrant being issued pursuant to Section 8(a) or Section 8(c), the Warrant Shares designated by the Holder which, when added to the number of shares of Common Stock underlying the other new
Warrants issued in connection with such issuance, does not exceed the number of Warrant Shares then underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance
Date, and (iv) shall have the same rights and conditions as this Warrant. 
 9. NOTICES. Whenever
notice is required to be given under this Warrant, unless otherwise provided herein, such notice shall be given by first class mail prepaid at such Holder’s address as it appears on the books of the Company, as furnished by such Holder to the
Company from time to time, receipt of such notice to be confirmed by such Holder by electronic transmission to the Company at ______________. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this
Warrant, including in reasonable detail a description of such action and the reason therefor. Without limiting the generality of the foregoing, any Exercise Notice to be delivered to the Company by a Holder pursuant to Section 1(a) hereof
(together with any written notice required to be delivered pursuant to Section 1(a)(ii)(B)) will be delivered by such Holder both by first class mail prepaid or overnight delivery to the Company at 2001 Bryan Street, Suite 1600, Dallas Texas
75201, Attn.: General Counsel, and by electronic transmission to the Company at ___________. In addition, without limiting the generality of the foregoing, the Company will give written notice to the Holder (i) promptly upon any adjustment of
the Exercise Price, setting forth in reasonable detail, and certifying, the calculation of such adjustment and (ii) at least fifteen (15) days prior to the date on which the Company closes its books or takes a record (A) with respect
to any dividend or 

  
 12 

 
distribution upon the shares of Common Stock, (B) with respect to any grants, issuances or sales of any Options, Convertible Securities or rights to purchase stock, warrants, securities or
other property to holders of shares of Common Stock or (C) for determining rights to vote with respect to any Fundamental Transaction, dissolution or liquidation; provided in each case that such information shall be made known to the
public prior to or in conjunction with such notice being provided to the Holder. 
 10. AMENDMENT AND
WAIVER. Except as otherwise provided herein, the provisions of this Warrant may be amended and the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained
the written consent of the Holder. 
 11. GOVERNING LAW. This Warrant shall be governed by and construed
and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Warrant shall be governed by, the internal laws of the State of New York, without giving effect to any choice of law or
conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. The Company hereby irrevocably submits to the
exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein,
and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or
that the venue of such suit, action or proceeding is improper. The Company hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at
the address it set forth on the signature page hereto and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in
any manner permitted by law. Nothing contained herein shall be deemed or operate to preclude the Holder from bringing suit or taking other legal action against the Company in any other jurisdiction to collect on the Company’s obligations to the
Holder, to realize on any collateral or any other security for such obligations, or to enforce a judgment or other court ruling in favor of the Holder. THE COMPANY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY
TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS WARRANT OR ANY TRANSACTION CONTEMPLATED HEREBY. 
 12. CONSTRUCTION; HEADINGS. This Warrant shall be deemed to be jointly drafted by the Company and all the Buyers and shall not be construed against any person as the drafter hereof. The headings of
this Warrant are for convenience of reference and shall not form part of, or affect the interpretation of, this Warrant. 
  

  
 13 

 13. DISPUTE RESOLUTION. In the case of a dispute as to the
determination of the Exercise Price or the arithmetic calculation of the Warrant Shares, the Company shall submit the disputed determinations or arithmetic calculations via facsimile within two (2) Business Days of receipt of the Exercise
Notice giving rise to such dispute, as the case may be, to the Holder. If the Holder and the Company are unable to agree upon such determination or calculation of the Exercise Price or the Warrant Shares within three (3) Business Days of such
disputed determination or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) Business Days submit via facsimile (a) the disputed determination of the Exercise Price to an independent, reputable
investment bank selected by the Company and approved by the Holder or (b) the disputed arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The Company shall cause at its expense the investment
bank or the accountant, as the case may be, to perform the determinations or calculations and notify the Company and the Holder of the results no later than ten (10) Business Days from the time it receives the disputed determinations or
calculations. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be binding upon all parties absent demonstrable error. 

14. REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Warrant shall be
cumulative and in addition to all other remedies available under this Warrant and the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the
right of the Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the
remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of this Warrant shall be entitled, in addition to all other available remedies, to an injunction
restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 
 15. LEGENDS. 
 (a) Restrictive Legends. Except as
otherwise permitted by this Section 15, each Warrant (including each Warrant issued upon the transfer of any Warrant) shall be stamped or otherwise imprinted with a legend in substantially the following form: 

“NEITHER THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE
SECURITIES ARE EXERCISABLE HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN
EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL SELECTED BY THE HOLDER, IN A FORM REASONABLY SATISFACTORY TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER

 Except as otherwise permitted by this Section 15, each certificate for Common Stock (or
Other Securities) issued upon the exercise of any Warrant, and each certificate issued upon the transfer of any such Common Stock, shall be stamped or otherwise imprinted with a legend in substantially the following form: 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, OR (B) AN OPINION OF COUNSEL SELECTED BY THE HOLDER, IN A FORM REASONABLY SATISFACTORY TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT.
NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.” 

(b) Termination of Restrictions. The restrictions imposed on the transferability of securities set forth in the
legend of this Warrant shall cease and terminate as to any particular securities (i) when a registration statement with respect to the sale of such securities shall have been declared effective under the Securities Act and such securities shall
have been disposed of in accordance with such registration statement, (ii) when such securities are sold pursuant to Rule 144 or Rule 144A (or any similar provision then in force) under the Securities Act, or (iii) when such restrictions
are no longer required or necessary in order to protect the Company against a violation of the Securities Act upon any sale or other disposition of such securities without registration thereunder. Whenever such restrictions shall cease and terminate
as to any such Securities, the holder thereof shall be entitled to receive from the Company, without expense, new securities of like tenor not bearing the legend set forth in this Warrant. 

(c) Subject to compliance with Sections 15(a) and 15(b), if applicable, this Warrant, the Warrant Shares
and all rights hereunder are freely transferable in whole or in part, without consent of the Company and without charge to the Holder hereof. 
 (d) The Company acknowledges and agrees that the Warrants and the Warrant Shares may be pledged by the Holder in connection with a bona fide margin agreement or other loan or financing arrangement that is
secured by such securities. The pledge of the Warrant or the Warrant Shares shall not be deemed to be a transfer, sale or assignment of such securities hereunder, and no Holder effecting a pledge of such securities shall be required to

  
 15 

 
provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement. The Company hereby agrees, subject to applicable securities laws, to execute
and deliver such documentation as a pledgee of such securities may reasonably request in connection with a pledge of such securities to such pledgee by a Holder. 

16. LISTING; REPORTING STATUS. 

(a) The Company shall secure the listing of all of the Warrant Shares promptly upon issuance of the Warrants, upon each

all of the Warrant Shares from time to time issuable under the terms of the Warrants. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 16. 

(b) For the avoidance of doubt, this Warrant shall not limit the Company’s right to delist, deregister, or
otherwise effect any Fundamental Transaction 
 17. SEVERABILITY. If any provision of this Warrant is
prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it
would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so modified continues to express, without material change,
the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of
the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid
provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).
