Section 4.06 RESERVED 

Section 4.07 Purchaser Preemptive Rights. 

(a) Prior to the Company directly or indirectly issuing additional Common Stock or other equity securities of the Company convertible into,
exercisable for or exchangeable into Common Stock (collectively, the “New Common Stock”), the Purchaser shall have the right to purchase the number of shares of New Common Stock in accordance with this Section 4.07. 

(b) The Company shall give Purchaser at least 10 days’ prior written notice (the “Preemptive Right Notice”) of any
proposed issuance of New Common Stock, which notice shall 

  
 28 

 
set forth in reasonable detail the proposed terms and conditions thereof and shall offer the Purchaser the opportunity to purchase its Pro Rata Share (which Pro Rata Share shall be calculated as
of the date of such notice) of the New Common Stock at the same price, on the same terms and conditions as the New Common Stock is proposed to be issued by the Company, subject to Section 4.07(d). If the Purchaser wishes to exercise its
preemptive rights, it must do so by delivering an irrevocable written notice to the Company within 5 days after delivery by the Company of the Preemptive Right Notice, which notice shall state the dollar amount of New Common Stock that the Purchaser
would like to purchase up to a maximum amount equal to the Purchaser’s Pro Rata Share of the aggregate offering amount. 
 (c)
Notwithstanding anything in this Section 4.07 to the contrary, the provisions of this Section 4.07 shall not apply to issuances of New Common Stock by the Company as follows: 

(i) Any issuance of New Common Stock upon the conversion or exercise or exchange (including redemption) of any Series B
Preferred Stock, Series D Preferred Stock, Series E Preferred Stock, Participation Rights Value, Warrants or any other options, warrants or other securities convertible into, or exercisable or exchangeable for, equity securities, provided that (in
the case of such other options, warrants or other securities) such issuance is pursuant to the terms of this Agreement, including this Section 4.07; 

(ii) Any issuance of New Common Stock pursuant to a compensatory plan, agreement or arrangement that has been approved by the
board of directors of the Company (or the requisite holders of Common Stock (if required by applicable Law)); 
 (iii) Any
issuance of New Common Stock in connection with any combination, stock split, recapitalization (other than in respect of any securities issued with respect to any new investment made in connection with such recapitalization) or reclassification of
the Common Stock; 
 (iv) Any issuance of New Common Stock as a dividend on any existing class or series of capital stock of
the Company; 
 (v) Any issuance of New Common Stock as consideration in any business combination or acquisition transaction
involving the Company or any of its direct or indirect Subsidiaries or in any joint venture; or 
 (vi) Any issuance of New
Common Stock for which an adjustment is otherwise provided under the Warrants. 
 (d) If the Purchaser or the Company reasonably believes,
based on the written opinion of legal counsel, that any regulatory or stockholder approval, including under applicable anti-trust Laws or applicable rules and regulations of any national securities exchange or over-the-counter market on which the
Common Stock is listed for trading, is required prior to the Purchaser purchasing the New Common Stock it has elected to purchase pursuant to this Section 4.07, the Purchaser shall not be required to make such purchase, and the Company shall
delay such issuance of the New Common Stock to either the Purchaser or the applicable third party 

  
 29 

 
until such approval has been obtained (or, in the case of applicable anti-trust Laws, the required filings have been completed and any applicable waiting period has expired). The Company shall
use reasonable best efforts to comply promptly with all applicable regulatory requirements related to obtaining such approvals. In no event shall the Purchaser be deemed to have failed to purchase any New Common Stock for purposes of
Section 4.07(e) as a result of its inability to make such purchase prior to such compliance in accordance with this Section 4.07(d). If this Section 4.07(d) applies, nothing in this Section 4.07 shall prevent the Company from
proceeding with the issuance of the New Common Stock to the proposed purchasers other than the portion of the New Common Stock that the Purchaser has elected to purchase pursuant to this Section 4.07. 

Section 4.08 Termination. In the event the Purchaser and its Permitted Transferees, collectively, hold less than 10% of the
outstanding Purchased Series E Preferred Stock, originally issued at Closing, (or if all the Purchased Series E Preferred Stock is exchanged into Subordinated Notes pursuant to Section 2.06, less than 10% of the aggregate principal amount
outstanding of the Subordinated Notes), all obligations of the Company, and all rights of the Purchaser and its Permitted Transferees under this Article IV will terminate immediately, provided that (i) the covenant in Section 4.09 shall
terminate at Closing and (ii) the covenant in Section 4.10 shall survive until Purchaser and its Permitted Transferees, collectively, hold less than 10% of the Warrant Shares (determined as an as exercised basis) originally issuable under
the Warrants (subject to adjustment for any stock splits, reverse split, combination or similar transaction). 
 Section 4.09
Interim Operating Covenants. Unless the Company has received the prior written consent or waiver of the Purchaser, the Company hereby covenants and agrees that, between the date hereof and the Closing: 

(a) the Company shall not, and shall not permit any Subsidiary thereof to, cause to be issued any capital stock or securities convertible or
exercisable into capital stock of the Company or such Subsidiary other than the Securities to the Purchaser and other than pursuant to the exercise or settlement of stock options, warrants or other rights therefor outstanding as of the date hereof
or grants of equity or equity based awards under the Company’s or any of its Subsidiary’s compensation plan or agreements; 
 (b)
the Company shall promptly notify the Purchaser upon the Company becoming aware of any new litigation filed, or threatened to be filed, against the Company or any of its Subsidiaries which could reasonably be expected to have a Material Adverse
Effect; 
 (c) the Company shall not declare or pay any dividends on or make any distributions in respect of any of its capital stock; or

 (d) the Company shall not amend its certificate of incorporation or by-laws except as required to effect the transactions contemplated by
this Agreement. 
 Section 4.10 Renewed Rights Agreement Amendment. The Company shall not amend the Renewed Rights Agreement in
a manner that adversely effects the exclusion of the issuance of the Securities (and any shares of Common Stock issuable upon exercise of the Warrants) from triggering the issuance of Series 4 Junior Participating Class C Preferred Stock. 

  
 30 

 Subject to Section 7.04(b), until termination in accordance with Section 4.08, any Permitted Transferee
Holding Preferred Shares in accordance with Section 7.05 shall be entitled to the benefits of Section 4.01 – 4.09 as a “Purchaser” to the extent of the Preferred Shares held by it and any Permitted Transferee holding
Warrants or Warrants Shares in accordance with Section 7.05 shall be entitled to the benefits of Section 4.07 and 4.10 as a “Purchaser” to the extent of the Warrant Shares held by it (on an as exercised basis).

purchase of the Securities.

Securities Act is 

  
 32

INDEMNIFICATION 

Section 6.01 Indemnification by the Company. The Company agrees to indemnify the Purchaser, its Affiliates and the respective
Representatives (the “Purchaser Related Parties”) from all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever (including any expenses reasonably incurred in connection with investigating, defending or
preparing to defend any related Claim) (“Losses”), and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action
(“Claims”), and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all Losses, whether or not involving a Third Party Claim, as a result of, arising out of, or in any way related to: 

(a) any inaccuracy of any of the representations or warranties made by the Company in this Agreement or in any certificate delivered by or on
behalf of the Company pursuant to this Agreement as of the date made or (unless such representation and warranty is made as of a specific date) as of the Closing Date; or 

(b) the breach or non-fulfillment of any covenant, agreement or obligation of the Company contained herein; 

provided that, in the case of the immediately preceding clause (a), such claim for indemnification is made prior to the applicable expiration of such
representation or warranty as set forth in Section 7.02; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a Purchaser Related Party shall have given notice (stating in
reasonable detail the basis of the claim for indemnification) to the Company shall constitute the date upon which such claim has been made. 

Section 6.02 Indemnification by the Purchaser. The Purchaser agrees to indemnify the Company, its Affiliates and their respective
Representatives (collectively, the “Company Related Parties”) from Losses, and hold each of them harmless against, any and all Claims, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all
Losses, whether or not involving a Third Party Claim, as a result of, arising out of, or in any way related to 
 (a) any inaccuracy of any
of the representations or warranties made by the Purchaser in this Agreement or in any certificate delivered by or on behalf of the Purchaser pursuant to this Agreement as of the date made or (unless such representation and warranty is made as of a
specific date) as of the Closing Date; or 
 (b) the breach or non-fulfillment of any covenant, agreement or obligation of the Purchaser
contained herein; 
 provided that, in the case of the immediately preceding clause (a), such claim for indemnification relating to a breach of any
representation or warranty is made prior to the expiration of such applicable representation or warranty pursuant to Section 7.02; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon
which a Company Related Party shall have given notice (stating in reasonable detail the basis of the 

  
 34 

 
claim for indemnification) to such Purchaser shall constitute the date upon which such claim has been made; provided, further, that the liability of the Purchaser shall not be greater in amount
than the sum of the Purchase Price for the Securities. 
 Section 6.03 Indemnification Procedure. 

(a) A claim for indemnification for any matter not involving a Third Party Claim may be asserted by notice to the party from whom
indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification which it may claim in accordance with this Article VI, except as otherwise
provided in Section 6.01 and Section 6.02. 
 (b) Promptly after any Company Related Party or Purchaser Related Party
(hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes is an indemnifiable claim
under this Agreement (each a “Third Party Claim”), the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) reasonably prompt written notice of such Third Party Claim, but failure to so
notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall
state the nature and the basis of such Third Party Claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified
Party, any such matter. If the Indemnifying Party undertakes to defend or settle, it shall promptly, and in no event later than 30 days, notify the Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the
Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation shall include furnishing the Indemnifying Party with any books, records and other information reasonably
requested by the Indemnifying Party and in the Indemnified Party’s possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party
of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the
Indemnified Party in connection with any defense or settlement of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted
liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has, within thirty days of when the Indemnified Party provides written notice of a Third Party Claim, failed (1) to assume the defense or
employ counsel reasonably acceptable to the Indemnified Party and (2) notify the Indemnified Party of such assumption or (B) the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the
Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party
reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such
action, with the expenses and fees of such separate counsel and other expenses related to such participation to 

  
 35 

 
be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of
the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability (in a form reasonably satisfactory to such Indemnified Party) of, and does not include any admission of
wrongdoing or malfeasance by, the Indemnified Party. The remedies provided for in this Section 6.03 are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise. 

Section 6.04 Waiver of Consequential and Punitive Damages. No party shall have any liability to any other party (or to any other
Purchaser Related Party or Company Related Party) for any special, consequential or punitive damages (“Excluded Claims”) as a result of any claim arising under or relating to the transactions contemplated under this Agreement including,
without limitation, any claim under Article VI and each party hereby waives to the maximum extent permitted by applicable Law any such Excluded Claims; provided, however, that such limitation shall not prevent any Purchaser Related
Party or Company Related Party from recovering under this Article VI for any such damages to the extent that such damages are payable to a third party in connection with any Third Party Claims. 

Section 6.05 Exclusive Remedy. Other than with respect to claims for fraud or intentional breach, each party acknowledges and
agrees that, following the Closing, subject to Section 7.12, such party’s sole and exclusive remedy with respect to any and all claims for any breach of any representation, warranty, covenant, agreement or obligation set forth herein or
otherwise relating to the subject matter of this Agreement, shall be pursuant to the indemnification provisions set forth in this Article VI or, in the case of termination, as otherwise expressly provided in Section 7.03. In furtherance of the
foregoing, each party hereby waives, to the fullest extent permitted under Law, any and all rights, claims and causes of action for any breach of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating
to the subject matter of this Agreement it may have against the other parties hereto and their Affiliates and each of their respective Representatives arising under or based upon any Law, except pursuant to the indemnification provisions set forth
in this Article VI or with respect to claims for fraud or intentional breach. Notwithstanding the foregoing, nothing in this Section VI shall limit any Person’s right to seek and obtain specific performance or any other form of equitable relief
to which any Person shall be entitled under applicable Law or assert a claim of fraud or intentional breach. 
 Section 6.06 Tax
Matters. All indemnification payments under this Article VI shall be adjustments to the Purchase Price, except as otherwise required by applicable Law. 

Section 6.07 Effect of Investigation. Neither the representations, warranties and covenants of the Company, nor the right to
indemnification of any Purchaser Related Party making a claim under this Article VI with respect thereto, shall be affected or deemed waived by reason of any investigation made by or on behalf of a Purchaser Related Party (including by any of its
Representatives) or by reason of the fact that a Purchaser Related Party or any of its Representatives knew or should have known that any such representation or warranty is, was or might be inaccurate or by reason of a Purchaser Related Party waiver
of any condition set forth in Section 2.05.

word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately following it. Any reference in this
Agreement to $ shall mean U.S. dollars. If any provision in the Basic Documents is held to be illegal, invalid, not binding or unenforceable, (a) such provision shall be fully severable and the Basic Documents shall be construed and enforced as
if such illegal, invalid, not binding or unenforceable provision had never comprised a part of the Basic Documents, and the remaining provisions shall remain in full force and effect and (b) the applicable parties hereto shall negotiate in good
faith to modify the Basic Documents so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest
extent possible. When calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to the Basic Documents, the date that is the reference date in calculating such period shall be excluded.
If the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day. Any words imparting the singular number only shall include the plural and vice versa. The words such as “herein,”
“hereinafter,” “hereof” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires. The provision of a Table of Contents, the
division of this Agreement into Articles, Sections and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting this Agreement. The term

the Closing and remain operative and in full force and effect in accordance with the terms thereof regardless of acceptance of any of the Securities and payment therefor, provided that the covenants of the Company set forth in Article IV shall
terminate as provided in Section 4.08. Regardless of any purported general termination of this Agreement, the provisions of Article VI and all indemnification rights and obligations of the Company and the Purchaser thereunder, and this
Article VII shall remain operative and in full force and effect as between the Company and the Purchaser with respect to any breach occurring prior to such termination, unless the Company and the Purchaser execute a writing that expressly (with
specific references 

  
 37 

 
to the applicable Section or subsection of this Agreement) terminates such rights and obligations as between the Company and the Purchaser. The intended effect of termination of representations
and warranties pursuant to this Section 7.02 (and indemnification rights with respect thereto) is to bar, from and after the date of termination, any claim or cause of action based on alleged inaccuracy of such representation or breach of such
representation and warranty or any claim to indemnity with respect thereto and the parties hereby waive any such claims or causes of action from and after the date of such termination. 

Section 7.03 Termination. 

(a) This Agreement may be terminated at any time prior to the Closing only as follows:

(ii) by the Company by written notice to the Purchaser if the Purchaser is in material breach of any representation, warranty

 (iii) by the Purchaser by written notice to the Company if the Company is
in material breach of any representation, warranty or covenant under this Agreement (and the Purchaser is not then in material breach of any representation, warranty or covenant) which breach if not cured would result in a failure to satisfy a

December 31, 2015 New York, New York time (the “Drop Dead Date”) (unless the terminating party is in breach of any of its covenants and obligations hereunder). 

Each party’s right of termination hereunder is in addition to any of the rights it may have hereunder.

advisory committee members, investment committee members, limited partners, investors, managers and advisors (including legal counsel) (the “Permitted Recipients”) to whom such disclosure is necessary and who in each case either

or (C) as may be requested or required by any Governmental Authority (provided that the Purchaser first, to the extent legally permissible, notifies the Company and gives the Company the opportunity to contest such request or
requirement, in each case as permitted by applicable Law). As used in this Agreement, “Confidentiality Period” shall mean the earlier of (i) 90 days after the later of (A) the Board Designation Termination Date (as defined

 (b) The Company and the Board shall take all actions necessary or advisable to
effect the provisions of Section 1(a) (subject to Section 1(c)), including, effective as of the date of this Agreement, validly appointing one Purchaser Designated Director to each of the three classes of Directors of the
Company, each to serve an initial term that expires no earlier than the annual meeting of the stockholders of the Company (the “Stockholders”) to be held in 2016, 2017 and 2018, respectively.

(ii) Each of the Purchaser, on the one hand, and the Golsen Holders, on the other hand, agree (A) upon the Company’s
request to, and to cause each Designated Director designated by it or them, as applicable, to, timely provide the Company with accurate and complete information relating to such Designated Director as may be required to be disclosed by the Company
under the Exchange Act and (B) to cause each Designated Director designated by it or them, as applicable, to comply with the Section 16 filing obligations under the Exchange Act. At each applicable election of Directors, the Board shall
nominate each Designated Director, which designee must meet the standards set forth in subsection (a) above, as part of the slate of Directors nominated by the Board for election by the Stockholders and shall recommend that the Stockholders
vote for the each of the Designated Directors (and if any Designated Director and any non-Designated Directors are each the subject of any third party solicitation of proxies or written consents against the election of such Directors, the Company
will recommend that the Stockholders vote for the election of the Designated Director in a manner substantially similar to the manner in which it recommends that the Stockholders vote for such other Directors). Additionally, in the event of the
resignation, death, or removal (for cause or otherwise) of any Designated Director, the Purchaser or the Golsen Holders who designated such Director shall have the right for the ensuing 30 days, subject to the other provisions of this
Section 1, to designate in writing furnished to the Nominating and Governance Committee the person to be appointed by the Board as the Designated Director to fill the resulting vacancy (subject to such designee meeting the standards set
forth in subsection (a) above). 
 (iii) Any action by the Purchaser or the Golsen Holders to designate a Designated
Director shall be evidenced in writing furnished to the Nominating and Governance Committee not later than January 31 of the year in which the annual meeting of the Stockholders for the election of such Designated Director is to be held (or in
the case of a special meeting within a reasonable time in advance of such meeting in order to allow the Board and the Nominating and Governance Committee to determine compliance with the qualifications required in Section 1 and otherwise
to comply with its proxy solicitation and disclosure obligations in connection with such meeting) and shall be executed by the Purchaser or the Golsen Holders, as applicable. 

(iv) In the event that the Purchaser or the Golsen Holders fail to designate a Designated Director meeting the qualifications
specified in Section 1 in accordance with the time periods set forth in this Section 1(b) (including upon the resignation, death or removal of a Designated Director), the Board, upon

 
recommendation from the Nominating and Governance Committee, shall have the right to retain the resulting vacancies on the Board, reduce the size of the Board to the extent of the resulting
vacancies or designate an individual or individuals recommended by the Nominating and Governance Committee to fill such vacancies, in each case until the next meeting of the Stockholders for the election of Directors of that class, at which time the
Purchaser or the Golsen Holders, as applicable, will again be entitled to designate Designated Directors to the extent permitted in this Section 1. Unless otherwise recommended by the Nominating and Governance Committee, any Directors so
designated by the Board to fill such vacancies shall satisfy the independence requirements of the NYSE or any other national securities exchange on which the Company’s Common Stock is listed or admitted to trading. 

(c) From and after the Closing and until the Board Designation Termination Date, the Purchaser shall be entitled to designate up to three
(3) Purchaser Designated Directors pursuant to this Section 1; provided, however, that, from and after the redemption in full of all of the Purchased Series E Preferred Stock held by the Purchaser and its Permitted
Transferees (the “Redemption Termination Date”), (i) so long as the Purchaser and its Permitted Transferees, collectively, continue to beneficially own at least 25% of the shares of Common Stock issuable upon exercise of the
Warrants (whether owned following exercise of the Warrants or as a right to acquire such shares of Common Stock upon exercise of the Warrants), the Purchaser shall only be entitled to designate up to two (2) Purchaser Designated Directors and
(ii) so long as the Purchaser and its Permitted Transferees, collectively, continue to beneficially own at least 10% (but not greater than 24.99%) of the shares of Common Stock issuable upon exercise of the Warrants (whether owned following
exercise of the Warrants or as a right to acquire such shares of Common Stock upon exercise of the Warrants), the Purchaser shall only be entitled to designate one (1) Purchaser Designated Director. From and after the Closing until the Golsen
Holders Board Designation Termination Date, the Golsen Holders shall be entitled to designate up to two (2) Golsen Holders Designated Directors pursuant to this Section 1; provided, however, so long as the Golsen Holders,
collectively, continue to beneficially own at least 2.5% (but not 5% or more) of the then outstanding Common Stock, the Golsen Holders shall only be entitled to designate up to one (1) Golsen Holders Designated Director. Notwithstanding the
foregoing, (x) the rights of the Purchaser to designate any Purchaser Designated Directors pursuant to this Section 1 shall immediately cease and terminate on the first date on which the Purchaser and its Permitted Transferees,
collectively, no longer beneficially own at least 10% of the Common Stock issuable upon exercise of the Warrants (whether owned following exercise of the Warrants or as a right to acquire such Common Stock upon exercise of the Warrants) (such date,
the “Board Designation Termination Date”) and (y) the rights of the Golsen Holders to designate any Golsen Holders Designated Directors pursuant to this Section 1 shall immediately terminate on the first date on
which the Golsen Holders, collectively, no longer beneficially own at least 2.5% of the then outstanding Common Stock (such date, the “Golsen Holders Board Designation Termination Date”). At any time on or after the Redemption
Termination Date, the Board Designation Termination Date or the Golsen Holders Board Designation Termination Date, the Board shall be entitled to accept and make effective the resignations of any Designated Directors in excess of the number of
Designated Directors that the Purchaser or the Golsen Holders, as applicable, are entitled to designate pursuant to this Section 1(c); provided, however, that the Purchaser or the Golsen Holders, as applicable, shall be entitled
to specify (by written notice to the Company) which Designated Directors’ resignations shall be so accepted and made 

 
effective if the number of required resignations hereunder is less than the number of then serving Designated Directors designated by the Purchaser or the Golsen Holders, as applicable. In
addition to the obligation in Section 1(a) of each Designated Director to deliver the written resignation described therein, after the Redemption Termination Date, the Board Designation Termination Date or the Golsen Holders Board
Designation Termination Date, as applicable, each of the Purchaser, on the one hand, and the Golsen Holders, on the other hand, agree, promptly upon (and in any event within two (2) Business Days following) receipt of a written request from the
Company, to cause the Designated Directors then serving as members of the Board in excess of the number of Designated Directors that it or they are entitled to designate pursuant to this Section 1(c), as applicable, to resign from the
Board effective immediately. 
 (d) At all times while a Designated Director is serving as a member of the Board, and following any such
Designated Director’s death, resignation, removal or other cessation as a Director in such former Designated Director’s capacity as a former Director, such Designated Director shall be entitled to all rights to indemnification and
exculpation, in each case, as are then made available to any other member of the Board. While serving as a Designated Director, such Designated Director shall be entitled to compensation commensurate with that of similarly situated (i.e.,
independent, employee or non-employee affiliate) members of the Board and reimbursement for reasonable expenses consistent with the Company’s policies applicable to other similarly situated Directors. 

(e) The option and right to appoint Designated Directors granted to each of the Purchaser and the Golsen Holders by the Company under this
Section 1 may not be transferred or assigned, in whole or in part, by the Purchaser or the Golsen Holders directly or indirectly (including by way of direct or indirect transfers of equity interests in such Persons) without the prior
written consent of the Company (provided that direct or indirect transfers of equity interests in such Person among or to (i) in the case of the Purchaser Parties, Todd Boehly and his direct or indirect controlled Affiliates or (ii) an
Affiliate thereof shall not be deemed to be an assignment hereunder so long as, with respect to transfers pursuant to clause (ii) above, such transfers collectively would not result in equity interests in such Person representing a majority of
the economic or voting interests in such Person being owned or controlled by a Person or Persons that do not own or control a majority of the economic or voting interests in such Person immediately prior to such transfer. 

(f) The Board shall not designate an executive committee or any other committee which has been delegated authority substantially similar to
the authority of the Board unless each then serving Purchaser Designated Director is also appointed as a member of such committee. Unless prohibited by applicable law or the rules of the NYSE (or any other national securities exchange on which the
Company’s Common Stock is listed or admitted to trading), each of the Compensation Committee, the Audit Committee and the Nominating and Corporate Governance Committee of the Board shall include one then serving Purchaser Designated Director as
timely designated in writing by the Purchaser. 
 (g) Each of the Golsen Holders hereby appoints J. Golsen to serve as the Golsen
Representative (the “Golsen Representative”) for purposes of this Agreement and to act as the agent of the Golsen Holders with respect to (i) the giving of any notice or instruction that is required or permitted to be given or
which may be given by the Golsen Holders under the 

 
terms of this Agreement, (ii) the execution and delivery on behalf of the Golsen Holders of any amendment or supplement to this Agreement and (iii) the execution and delivery of any
waiver or extension on behalf of the Golsen Holders under the terms of this Agreement. It is acknowledged that the actions to be taken by the Golsen Representative on behalf of the Golsen Holders under the terms of this Agreement are ministerial in
nature and that the Golsen Representative shall only take such actions as may be authorized or instructed by the Golsen Holders and that the Golsen Representative shall not have any liability to the other Golsen Holders for any actions or omission
by the Golsen Representative, in such capacity. Each of the Golsen Holders hereby authorizes each of the other parties to this Agreement to conclusively and absolutely rely, without inquiry, upon any action taken by the Golsen Representative as the
actions of each Golsen Holder in all matters referred to in this Section 1(g). The Golsen Representative may be removed at any time hereunder, with or without cause, by means of notice to such effect to the Company and the then serving Golsen
Representative from any one or more Golsen Holders, who individually or collectively, beneficially owns more than 50% of the outstanding Common Stock then owned by the Golsen Holders and its Affiliates (the “Majority of Golsen
Holders”). Within five business days after the effective date of the removal or resignation of the Golsen Representative, the Golsen Holders by a vote of a Majority of Golsen Holders shall select a successor Golsen Representative who must
be either a Golsen Holder or an Affiliate of a Golsen Holder and shall promptly give the Company notice of such selection. 

Section 2. VOTING OBLIGATIONS. 

(a) Each of the Parties (other than the Company) agrees that, provided that the Company is not in breach of its obligations under this
Agreement (including Section 1 hereof), during the Voting Period (as defined below), at any meeting of the Stockholders, however called, or at any adjournment or postponement thereof, or in connection with any written consent of the
Stockholders or in any other circumstances upon which a vote, consent or other approval of all or some of the Stockholders is sought solely with respect to the matters described in this Section 2, such Party shall vote (or cause to be
voted) or execute (or cause to be executed) consents with respect to, as applicable, all of the Company securities (including the Securities) owned (beneficially or of record) by such Party (or its Affiliates) as of the applicable record date in
favor of (FOR) the election of the persons named in the Company’s proxy statement as the Board’s nominees for election as Directors, and against any other nominees. 

(b) With respect to any vote of the Stockholders held during the Voting Period with respect to the matters set forth in
Section 2(a), each of the Parties (other than the Company) shall, and shall cause its Affiliates on any applicable record date to, appear at such meeting (in person or by proxy) or otherwise cause all of the Securities held by such Party
(or such Affiliates) to be counted as present thereat for purposes of establishing a quorum. Any vote required to be cast or consent required to be executed pursuant to this Section 2 shall be cast or executed in accordance with the
applicable procedures relating thereto so as to ensure that it is duly counted for purposes of recording the results of that vote or consent. 

(c) “Voting Period” means the period from and including the date of this Agreement through and including the annual meeting
of Stockholders to be held in 2016 (including any adjournments and postponements thereof). 

 Section 3. STANDSTILL. 

(a) During the period commencing on the Closing and ending on the Standstill Termination Date (as defined below), provided that the Company is
not in breach of its obligations under this Agreement (including Section 1 hereof), each of the Purchaser Parties (so long as such Purchaser Party is an Affiliate of the beneficial owner of the Company securities issued under the Purchase
Agreement) shall not, and shall cause its controlled Affiliates not to, directly or indirectly: 
 (i) engage in any hostile
or takeover activities with respect to the Company (including by means of a tender offer or soliciting proxies or written consents, other than as recommended by the Board); 

(ii) acquire or propose to acquire beneficial ownership of additional Common Stock (other than the Common Stock issuable upon
exercise of the Warrants) or other Company securities that in the aggregate, together with their beneficial ownership of any other Common Stock, is equal to beneficial ownership of twenty percent (20%) or more of the voting power of the
outstanding Common Stock (taking into account the voting rights of the Common Stock underlying the Warrants and the Series F Preferred Stock); provided that the foregoing shall not prohibit or apply to the receipt of any (A) Common Stock
paid as dividends on the Purchased Series E Preferred Stock held by the Purchaser or any of its Permitted Transferees or any Common Stock issued in exchange for the redemption of the Purchased Series E Preferred Stock held by the Purchaser or any of
its Permitted Transferees in each case in accordance with the Series E Certificate of Designations and the Purchase Agreement or (B) or (C) any New Common Stock issued to the Purchaser or any of its Permitted Transferees pursuant to
Section 4.07 of the Purchase Agreement, and such Series E Preferred Stock, Common Stock and New Common Stock shall not be taken into account for purposes of establishing compliance with the foregoing; 

(iii) acquire or propose to acquire any other securities of the Company or any securities of any Affiliates of the Company;

 (iv) call a special meeting of the Stockholders; or 

(v) propose to remove, or vote to remove, any Directors of the Company (other than a Purchaser Designated Director in
accordance with Section 1). 
 (b) Specifically, but without limiting Section 3(a), during the period commencing on the Closing
and ending on the Standstill Termination Date, without the prior written consent of the Company, each of the Purchaser Parties shall not, and shall cause its controlled Affiliates not to, directly or indirectly:

partnership, joint venture, acquisition or similar transaction involving the Company or any of its Affiliates or their properties, except as expressly permitted hereby

(vi) publicly disclose any intent, plan or arrangement inconsistent with this Agreement; or 

(vii) advise, assist or encourage others in connection with the above.

proposal to, the Board; 
 (ii) restrict in any manner how any Purchaser Party or its controlled Affiliates vote their Common
Stock or other Company securities, except as provided in Section 2;

(c) Interpretation. Section references in this Agreement are references to the corresponding Section to this Agreement, unless
otherwise specified. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended, supplemented and otherwise modified from time to time, unless
otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately following it.
If any provision in this Agreement is held to be illegal, invalid, not binding or unenforceable, (i) such provision shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid, not binding or
unenforceable provision had never comprised a part of this Agreement, and the remaining provisions shall remain in full force and effect and (ii) the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. When calculating

 
the period of time before which, within which or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period
shall be excluded, and if the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day. Any words imparting the singular number only shall include the plural and vice versa. The words such
as “herein,” “hereinafter,” “hereof” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires. The division of this
Agreement into Sections and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting this Agreement. 

(d) Governing Law; Submission to Jurisdiction. This Agreement, and all claims or causes of action (whether in contract or tort) that
may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in
connection with this Agreement), will be construed in accordance with and governed by the laws of the State of Delaware without regard to principles of conflicts of laws. Any action against any Party relating to the foregoing shall be brought in any
federal or state court of competent jurisdiction located within the State of Delaware, and the Parties hereto hereby irrevocably submit to the non-exclusive jurisdiction of any federal or state court located within the State of Delaware over any
such action. Each of the Parties agrees (i) that this Agreement involves at least $100,000.00, and (ii) that this Agreement has been entered into by the Parties in express reliance upon 6 Del. C. § 2708. Each of the Parties hereby
irrevocably and unconditionally agrees (1) that it is and shall continue to be subject to the jurisdiction of the courts of the State of Delaware and of the federal courts sitting in the State of Delaware, and (2)(A) to the extent that
such Party is not otherwise subject to service of process in the State of Delaware, to appoint and maintain an agent in the State of Delaware as such Party’s agent for acceptance of legal processes and notify the other Parties of the name and
address of such agent, and (B) to the fullest extent permitted by law, that service of process may also be made on such Party by prepaid certified mail with a proof of mailing receipt validated by the U.S. Postal Service constituting evidence
of valid service, and that, to the fullest extent permitted by applicable law, service made pursuant to (2)(A) or (B) above shall have the same legal force and effect as if served upon such Party personally within the State of Delaware.
Each of the Parties hereby irrevocably waives, to the fullest extent permitted by applicable law, any objection that it may now or hereafter have to the laying of venue of any such dispute brought in such court or any defense of inconvenient forum
for the maintenance of such dispute. Each of the Parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. 

(e) Waiver of Jury Trial. EACH OF THE PARTIES TO THIS AGREEMENT HEREBY WAIVES, AND AGREES TO CAUSE ITS AFFILIATES TO WAIVE, TO THE
FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS AGREEMENT OR (ii) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO
IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE. EACH OF THE PARTIES TO THIS

 
AGREEMENT HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN
ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. 

(f) No Waiver; Modifications in Writing. 

(i) Delay. No failure or delay on the part of any Party in exercising any right, power or remedy hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and
are not exclusive of any remedies that may be available to a Party at law or in equity or otherwise. 
 (ii) Specific
Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification or termination of any provision of this Agreement shall be effective unless signed by each of the Parties hereto; provided, however, that this Agreement
shall be deemed to be amended without the consent of the Parties hereto by the execution and delivery of a joinder agreement in the form of Annex B hereto solely for the purpose of adding a Purchaser Party to this Agreement. Any amendment,
supplement or modification of or to any provision of this Agreement, any waiver of any provision of this Agreement and any consent to any departure by a Party from the terms of any provision of this Agreement shall be effective only in the specific
instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on a Party in any case shall entitle such Party to any other or further notice or demand in similar
or other circumstances. Any investigation by or on behalf of any Party shall not be deemed to constitute a waiver by the Party taking such action of compliance with any representation, warranty, covenant or agreement contained herein. 

(g) Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different Parties hereto in separate
counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute one and the same agreement. 

(h) Binding Effect; Assignment; Termination. This Agreement will be binding upon and inure to the benefit of the Parties hereto and
their respective successors and permitted assigns, but will not be assignable or delegable by any Party hereto without the prior written consent of each of the other Parties. This Agreement shall terminate with respect to the Purchaser Parties (and
the Company’s rights with respect to and obligations to the Purchaser Parties) on the later of the Board Designation Termination Date and the Standstill Termination Date and with respect to the Golsen Holders (and the Company’s rights with
respect to and obligations to the Golsen Holders) on the Golsen Holders Board Designation Termination Date, except that in any such case the provisions of this Section 4 shall survive any termination of this Agreement and except that no
party to this Agreement shall be relieved or released from liability for damages arising out of a breach of this Agreement before such termination. 

 (i) Independent Counsel. Each of the Parties acknowledges that it has been represented by
independent counsel of its choice throughout all negotiations that have preceded the execution of this Agreement and that it has executed the same with consent and upon the advice of said independent counsel. Each Party and its counsel cooperated in
the drafting and preparation of this Agreement and the documents referred to herein, and any and all drafts relating thereto will be deemed the work product of the Parties and may not be construed against any Party by reason of its preparation.
Accordingly, any rule of law or any legal decision that would require interpretation of any ambiguities in this Agreement against the Party that drafted it is of no application and is hereby expressly waived. 

(j) Specific Enforcement. Each of the Parties acknowledges and agrees that monetary damages would not adequately compensate an injured
Party for the breach of this Agreement by any Party, that this Agreement shall be specifically enforceable and that any breach or threatened breach of this Agreement shall be the proper subject of a temporary or permanent injunction or restraining
order without a requirement of posting bond. Further, each Party hereto waives any claim or defense that there is an adequate remedy at law for such breach or threatened breach. 

(k) Further Assurances. Each of the Parties hereto shall, from time to time and without further consideration, execute such further
instruments and take such other actions as any other Party hereto shall reasonably request in order to fulfill its obligations under this Agreement to effectuate the purposes of this Agreement.

Form of Joinder Agreement 

JOINDER AGREEMENT 
 This
Joinder Agreement is made this      day of             , 20    , by and between
                     (the “Permitted Transferee”) and LSB Industries, Inc, a Delaware corporation (the “Company”),
pursuant to the terms of the Board Representation and Standstill Agreement dated as of December 4, 2015 by and among the Company, LSB Funding, LLC, a Delaware limited liability company (the “Purchaser”), and the other parties

WITNESSETH: 
 WHEREAS, the
Company and the Purchaser have agreed in the Purchase Agreement that all Persons to whom Securities are transferred in accordance with the Purchase Agreement must enter into a Joinder Agreement binding such Person as a Purchaser Party to the same

WARRANT TO PURCHASE COMMON STOCK 
 Warrant
No.: 2015-1 
 Number of Shares of Common Stock: FOUR MILLION ONE HUNDRED THREE THOUSAND SEVEN HUNDRED FORTY SIX (4,103,746) 

Date of Issuance: December 4, 2015 (“Issuance Date”) 

LSB Industries, Inc., a Delaware corporation (the “Company”), certifies that, for good and valuable consideration, the receipt and
sufficiency of which are acknowledged, LSB Funding LLC, a Delaware limited liability company, 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, upon surrender of this Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, the
“Warrant”), at any time or times on or after the Issuance Date, but not after 5:30 p.m., New York Time, on the Expiration Date (as defined below), FOUR MILLION ONE HUNDRED THREE THOUSAND SEVEN HUNDRED FORTY SIX
(4,103,746) fully paid and nonassessable shares of Common Stock (as defined below) (the “Warrant Shares”). This Warrant is one of a series of warrants to purchase shares of Common Stock (collectively, the
“Warrants”) issued pursuant to that certain Securities Purchase Agreement by and between the Company, the Holder and Security Benefit Corporation (as amended, restated, supplemented or otherwise identified from time to time, the
“Purchase Agreement”) dated December 4, 2015. In addition to the defined terms set forth in Section 18 herein, capitalized terms that are not otherwise defined herein shall have the meanings assigned to such terms in the
Purchase Agreement. 

 1. EXERCISE OF WARRANT. 

(a) Mechanics of Exercise. Subject to the terms and conditions hereof, this Warrant may be exercised by the Holder on any day on or
after the Issuance Date, in whole or in part (but not as to fractional shares), 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 and (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 or wire transfer of immediately available funds (a “Cash Exercise”) or (B) if the conditions for Cashless Exercise (as defined in Section 1(c)) set forth in Section 1(c) are satisfied, by
notifying the Company that this Warrant is being exercised pursuant to a Cashless Exercise (the items under (i) and (ii) above, the “Exercise Delivery Documents”). The Holder shall not be required to deliver the original
Warrant in order to effect an exercise hereunder. On or before the first Trading Day following the date on which the Company has received the Exercise Delivery Documents (the date upon which the Company has received all of the Exercise Delivery
Documents, the “Exercise Date”), the Company shall transmit by facsimile or e-mail transmission an acknowledgment of confirmation of receipt of the Exercise Delivery Documents to the Holder and the Company’s transfer agent for
the Common Stock (the “Transfer Agent”). The Company shall deliver any objection to the Exercise Delivery Documents on or before the second Trading Day following the date on which the Company has received all of the Exercise
Delivery Documents. On or before the third Trading Day following the date on which the Company has received all of the Exercise Delivery Documents (the “Share Delivery Date”), the Company shall cause the Transfer Agent to register
by book entry, as described in Section 1(h) below, the transfer and delivery of the Warrant Shares issuable to the Holder upon such exercise and deliver to the Holder an Ownership Notice (as defined in Section 1(h)) relating to such
Warrant Shares. Upon delivery of the Exercise Delivery Documents to the Company, 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 registration of such Warrant Shares in the Holder’s name or delivery of the Ownership Notice in respect thereof to Holder. If this Warrant is submitted in connection with any exercise 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 being acquired upon an exercise, then the Company shall as soon as practicable and in no event later than three
(3) Trading Days after any such submission and at its own expense, issue a new Warrant (in accordance with Section 7(e)) representing the right to purchase the number of Warrant Shares purchasable immediately prior to such exercise under
this Warrant, less the number of Warrant Shares with respect to which this Warrant has been and/or is exercised. The Company shall pay any and all transfer taxes and other expenses of the Company and the Holder(s) that may be payable with respect to
the issuance and delivery of Warrant Shares upon exercise of this Warrant; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the registration of any
certificates for Warrants in a name other than that of the Holder. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof. All
Warrant Shares issued upon the exercise of this Warrant pursuant to the terms hereof shall be validly issued, fully paid and non-assessable, issued without violation of any preemptive or similar rights of any stockholders of the Company and free and
clear of all liens. 

 (b) Exercise Price. For purposes of this Warrant, “Exercise Price” means
$0.10 per share of Common Stock, subject to adjustment as provided herein. 
 (c) Cashless Exercise. Notwithstanding anything
contained herein to the contrary, the Holder may, in its sole discretion, 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”): 

 

					
	 Net Number =
	 	 (A × B) - (A × 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 arithmetic average of the Weighted Average Price of the shares of Common Stock (as reported by Bloomberg) on fifteen
(15) Trading Days ending on the date immediately preceding the date of the Exercise Notice. 
 C = the Exercise Price then in
effect for the applicable Warrant Shares at the time of such exercise. 
 For purposes of Rule 144(d) promulgated under the Securities
Act of 1933, as amended (the “Securities Act”), as in effect on the date hereof, assuming the Holder is not an affiliate of the Company, 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 closing date of the offering pursuant to which the Company was obligated to issue this Warrant. 

(d) Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of
Warrant Shares to be issued pursuant to the terms hereof, the Company shall promptly issue to the Holder the number of Warrant Shares that are not disputed pending resolution of such dispute. 

(e) No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of
this Warrant. As to any fraction of a share that the Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the
Exercise Price. 
 (f) Exchange Act Filings. The Holder agrees and acknowledges that it shall have sole responsibility for making any
applicable filings with the U.S. Securities and Exchange Commission pursuant to Sections 13 and 16 of the Exchange Act as a result of its acquisition of any Warrant and the Warrant Shares and any future retention or transfer thereof. 

(g) Book Entry; Ownership Notice. Any Warrant Shares issued hereunder shall be in uncertificated, book-entry form, as permitted by the
Company’s Bylaws and the Delaware General Corporation Law. The Transfer Agent shall maintain the register for the 

 
Common Stock and such book-entry system. Upon any exercise of this Warrant, the Company shall deliver (or cause the Transfer Agent to deliver) to the Holder a screen shot of the Transfer
Agent’s records or such other instrument as the Transfer Agent shall typically issue in such circumstance indicating the registration of transfer to the Holder by book entry of the number of shares of Common Stock issuable to the Holder upon
such exercise of the Warrant (an “Ownership Notice”). The Transfer Agent’s records and any Ownership Notices shall contain the legend set forth at the beginning of this Warrant (or an equivalent notation reflecting the transfer
restrictions described in such legend) until such time as a legend is no longer required by the terms of the Purchase Agreement. 
 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 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(a) shall become effective at the close of business on the date the subdivision or combination becomes effective. 

(b) Notwithstanding anything to the contrary in this Warrant, in no event shall the Exercise Price be reduced below the par value of the
Company’s Common Stock. 
 (c) Special Distributions. In case the Company shall declare a dividend or make any other
distribution (excluding dividends of its Common Stock and other dividends or distributions referred to in Section 2(a)), including, without limitation, in cash, in property or assets, to holders of Common Stock (a “Special
Distribution”), then the Board shall make provision so that upon the exercise of the Warrant, the Holder or the Holder’s subsequent permitted transferee(s) shall be entitled to receive such dividend or distribution that the Holder
would have received had the Warrant been exercised immediately prior to the record date for such dividend or distribution. When a Special Distribution is made, the Company shall promptly notify the Holder of such event in writing and the dividend or
other distribution that such Holder is entitle to receive upon exercise of the Warrant. 
 3. FUNDAMENTAL TRANSACTIONS. 

(a) Upon the occurrence of any Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after
the date of such Fundamental Transaction, the provisions of this Warrant referring to the “Company” shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the obligations
of the Company under this Warrant with the same effect as if 

 
such Successor Entity had been named as the Company herein. Upon consummation of the Fundamental Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be
issued upon exercise of this Warrant at any time after the consummation of the Fundamental Transaction, in lieu of the shares of the Common Stock (or other securities, cash, assets or other property purchasable upon the exercise of the Warrant prior
to such Fundamental Transaction), such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights), if any, that the Holder would have been entitled to receive upon the
happening of such Fundamental Transaction had this Warrant been exercised immediately prior to such Fundamental Transaction, as adjusted in accordance with the provisions of this Warrant. In addition to and not in substitution for any other rights
hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock (a
“Corporate Event”), the Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive upon an exercise of this Warrant within 90 days after the consummation of the Fundamental
Transaction but, in any event, prior to the Expiration Date, in lieu of the shares of the Common Stock (or other securities, cash, assets or other property) purchasable upon the exercise of the Warrant prior to such Fundamental Transaction, such
shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights) which the Holder would have been entitled to receive upon the happening of such Fundamental Transaction had the
Warrant been exercised immediately prior to such Fundamental Transaction. Provision made pursuant to the preceding sentence shall be in a form and substance reasonably satisfactory to the Required Holders. The provisions of this Section shall apply
similarly and equally to successive Fundamental Transactions and Corporate Events and any adjustment under this Section 3 shall be without duplication for any adjustment or distribution made under Section 2. 

(b) In the event that the Company at any time 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 shares of Common Stock (the “Purchase Rights”) the then 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 the exercise of this Warrant),
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 determined for the grant, issue
or sale of such Purchase Rights. 
 4. NO DUPLICATIVE ADJUSTMENT; LIMIT ON ADJUSTMENTS. ANY ADJUSTMENTS OR DISTRIBUTION
RIGHTS UNDER ANY PROVISION OF SECTIONS 2 OR 3 SHALL BE MADE WITHOUT DUPLICATION FOR (I) ANY OTHER ADJUSTMENT OR PARTICIPATION RIGHT UNDER ANY OTHER PROVISION OF SECTION 2 OR 3 OR (II) ANY PRE-EMPTIVE RIGHTS UNDER SECTION 4.07 OF
THE PURCHASE AGREEMENT. IN ADDITION, IF THE HOLDER OR THE COMPANY REASONABLY BELIEVES, BASED ON THE WRITTEN OPINION OF LEGAL COUNSEL, THAT ANY REGULATORY OR STOCKHOLDER APPROVAL, INCLUDING UNDER APPLICABLE ANTI-TRUST LAWS OR APPLICABLE RULES AND
REGULATIONS OF ANY NATIONAL SECURITIES 

 
EXCHANGE OR OVER-THE-COUNTER MARKET ON WHICH THE COMMON STOCK IS LISTED FOR TRADING, IS REQUIRED PRIOR TO THE HOLDER ACQUIRING ANY PURCHASE RIGHTS IT HAS ELECTED, OR IS OTHERWISE
ENTITLED, TO ACQUIRE PURSUANT TO SECTION 3(B), THE HOLDER SHALL NOT BE REQUIRED TO MAKE SUCH ACQUISITION, AND THE COMPANY SHALL DELAY SUCH ISSUANCE OF THE PURCHASE RIGHTS TO THE HOLDER UNTIL SUCH APPROVAL HAS BEEN OBTAINED (OR, IN THE CASE OF
APPLICABLE ANTI-TRUST LAWS, THE REQUIRED FILINGS HAVE BEEN COMPLETED AND ANY APPLICABLE WAITING PERIOD HAS EXPIRED). THE COMPANY SHALL USE REASONABLE BEST EFFORTS TO COMPLY PROMPTLY WITH ALL APPLICABLE REGULATORY REQUIREMENTS RELATED TO OBTAINING
SUCH APPROVALS. IF THE PRECEDING SENTENCE OF THIS SECTION 4 APPLIES, NOTHING IN SECTION 3(B) SHALL PREVENT THE COMPANY FROM PROCEEDING WITH THE ISSUANCE OF THE PURCHASE RIGHTS TO THE OTHER HOLDERS OF COMMON STOCK WHO HAVE ELECTED, OR ARE
OTHERWISE ENTITLED, TO ACQUIRE SUCH PURCHASE RIGHTS OTHER THAN THE PORTION OF THE PURCHASE RIGHTS THAT THE HOLDER IS ENTITLED TO ACQUIRE PURSUANT TO SECTION 3(B). 

5. RESERVATION OF WARRANT SHARES. THE COMPANY COVENANTS THAT IT WILL AT ALL TIMES RESERVE AND KEEP AVAILABLE OUT OF THE
AGGREGATE OF ITS AUTHORIZED BUT UNISSUED AND OTHERWISE UNRESERVED COMMON STOCK, SOLELY FOR THE PURPOSE OF ENABLING IT TO ISSUE WARRANT SHARES UPON EXERCISE OF THIS WARRANT AS HEREIN PROVIDED, THE NUMBER OF SHARES OF COMMON STOCK WHICH ARE THEN
ISSUABLE AND DELIVERABLE UPON THE EXERCISE OF THIS ENTIRE WARRANT. THE COMPANY COVENANTS THAT ALL SHARES OF COMMON STOCK SO ISSUABLE AND DELIVERABLE SHALL, UPON ISSUANCE AND THE PAYMENT OF THE APPLICABLE EXERCISE PRICE IN ACCORDANCE WITH THE TERMS
HEREOF, BE DULY AND VALIDLY AUTHORIZED, ISSUED AND FULLY PAID AND NONASSESSABLE. IF, NOTWITHSTANDING THE FOREGOING, AND NOT IN LIMITATION THEREOF, 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 (THE “REQUIRED RESERVE AMOUNT”) EQUAL TO THE MAXIMUM NUMBER OF
SHARES OF COMMON STOCK AS SHALL FROM TIME TO TIME BE NECESSARY TO EFFECT THE EXERCISE OF ALL THIS WARRANT (WITHOUT REGARD TO ANY LIMITATIONS ON EXERCISE CONTAINED HEREIN) (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 ENTIRE WARRANT. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING
SENTENCE, AS SOON AS PRACTICABLE AFTER THE DATE OF THE OCCURRENCE OF AN AUTHORIZED 

 
SHARE FAILURE, BUT IN NO EVENT LATER THAN NINETY (90) DAYS AFTER THE OCCURRENCE OF SUCH AUTHORIZED SHARE FAILURE, THE COMPANY SHALL HOLD A MEETING OF ITS STOCKHOLDERS FOR THE APPROVAL OF AN
INCREASE IN THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK. IN CONNECTION WITH SUCH MEETING, THE COMPANY SHALL PROVIDE EACH STOCKHOLDER WITH A PROXY STATEMENT AND SHALL USE ITS REASONABLE BEST EFFORTS TO SOLICIT ITS STOCKHOLDERS’ APPROVAL OF
SUCH INCREASE IN AUTHORIZED SHARES OF COMMON STOCK AND TO CAUSE ITS BOARD OF DIRECTORS TO RECOMMEND TO THE STOCKHOLDERS THAT THEY APPROVE SUCH PROPOSAL. THE COMPANY SHALL NOT EFFECT ANY SUBDIVISION (BY WAY OF STOCK SPLIT, STOCK DIVIDEND,
RECAPITALIZATION OR OTHERWISE) OF ONE OR MORE CLASSES OF ITS OUTSTANDING COMMON STOCK INTO A GREATER NUMBER OF SHARES OF COMMON STOCK WHICH WOULD RESULT, PURSUANT TO SECTION 2(A) (WITHOUT GIVING EFFECT TO SECTION 2(B)), IN A REDUCTION OF
THE EXERCISE PRICE BELOW THE PAR VALUE OF THE SHARES OF COMMON STOCK THAN IN EFFECT UNLESS ON OR PRIOR TO SUCH SUBDIVISION THE PAR VALUE OF SUCH SHARES OF COMMON STOCK IS REDUCED TO THE EXTENT NECESSARY (OR ANOTHER ADJUSTMENT REASONABLY ACCEPTABLE
TO THE REQUIRED HOLDERS AND THE COMPANY IS MADE) TO PERMIT THE ADJUSTMENTS UNDER SECTION 2(A) WHICH WOULD OTHERWISE BE MADE IN CONNECTION THEREWITH, BUT FOR THE RESTRICTIONS OF SECTION 2(B), AND TO PERMIT THE WARRANTS TO BE EXERCISED INTO
WARRANT SHARES THAT ARE FULLY PAID AFTER GIVING EFFECT TO SUCH ADJUSTMENTS. 
 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. REGISTRATION AND REISSUANCE OF WARRANTS. 

(a) Registration of Warrant. The Company shall register this Warrant, upon the records to be maintained by the Company for that purpose
(the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any
distribution to the Holder, and for all other purposes, absent actual notice to the contrary. The Company shall also register any transfer, exchange, reissuance or cancellation of any portion of this Warrant in the Warrant Register. 

(b) Transfer of Warrant. This Warrant may not be transferred or assigned directly or indirectly (including by way of direct or indirect

surrender this Warrant to the Company together with all applicable transfer taxes, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Warrant (in accordance with Section 7(e)), registered as the Holder may

Section 7(e)) to the Holder representing the right to purchase the number of Warrant Shares not being transferred. 
 (c) 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 or the provision of reasonable security by the Holder to the Company 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 7(e)) representing the right to purchase the Warrant Shares then underlying this Warrant. 

(d) Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the surrender hereof by the Holder at the principal office
of the Company together with all applicable transfer taxes, for a new Warrant or Warrants (in accordance with Section 7(e)) 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 the Company shall not be required to issue Warrants for
fractional shares of Common Stock hereunder. 
 (e) Issuance of New Warrants. Whenever the Company is required to issue a new Warrant
pursuant to the terms of this Warrant, such new Warrant shall (i) be of like tenor with this Warrant, (ii) represent, as indicated on the face of such new Warrant, the right to purchase the Warrant Shares then underlying this Warrant (or

connection with such issuance, does not exceed the number of Warrant 

 
Shares then underlying this Warrant), (iii) have an issuance date, as indicated on the face of such new Warrant which is the same as the Issuance Date and (iv) have the same rights and
conditions as this Warrant. 
 8. NOTICES. WHENEVER NOTICE IS REQUIRED TO BE GIVEN UNDER THIS WARRANT, UNLESS OTHERWISE
PROVIDED HEREIN, SUCH NOTICE SHALL BE GIVEN IN ACCORDANCE WITH THE INFORMATION SET FORTH IN THE WARRANT REGISTER. THE COMPANY SHALL PROVIDE THE HOLDER WITH PROMPT WRITTEN NOTICE OF ALL ACTIONS TAKEN PURSUANT TO THIS WARRANT, INCLUDING, IN REASONABLE

MADE KNOWN TO THE PUBLIC PRIOR TO OR WITHIN THREE (3) BUSINESS DAYS OF SUCH NOTICE BEING PROVIDED TO THE HOLDER. 
 9.
NONCIRCUMVENTION. THE COMPANY HEREBY COVENANTS AND AGREES THAT THE COMPANY WILL NOT, BY AMENDMENT OF ITS CERTIFICATE OF INCORPORATION, 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. 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, AND (II) SHALL USE ALL REASONABLE EFFORTS TO TAKE ALL SUCH ACTIONS AS MAY BE NECESSARY OR APPROPRIATE IN ORDER THAT THE COMPANY MAY VALIDLY AND LEGALLY ISSUE FULLY PAID AND NONASSESSABLE SHARES
OF COMMON STOCK UPON THE EXERCISE OF THIS WARRANT. 

 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 REQUIRED HOLDERS. ANY AMENDMENT OR
WAIVER APPROVED BY REQUIRED HOLDERS AND ANY OTHER APPROVAL OR CONSENT GRANTED BY REQUIRED HOLDERS HEREUNDER SHALL BE EFFECTIVE AND BINDING ON ALL CURRENT AND FUTURE HOLDERS OF THE WARRANTS.

CONCERNING THE CONSTRUCTION, VALIDITY, INTERPRETATION AND PERFORMANCE OF THIS WARRANT SHALL BE GOVERNED BY, THE INTERNAL LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW PROVISION OR RULE (WHETHER OF THE
STATE OF DELAWARE OR ANY OTHER JURISDICTIONS) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTIONS OTHER THAN THE STATE OF DELAWARE. THE COMPANY AND HOLDER EACH HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF THE STATE
AND FEDERAL COURTS SITTING IN WILMINGTON, DELAWARE, 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 AND HOLDER EACH 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 THE ADDRESS OF SUCH PARTY SET FORTH IN
SECTION 7.08 OF THE PURCHASE AGREEMENT (OR AS OTHERWISE SPECIFIED IN ACCORDANCE WITH SUCH SECTION 7.08) 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 OR THE COMPANY FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION AGAINST THE OTHER
PARTY IN ANY OTHER JURISDICTION TO ENFORCE THIS WARRANT OR SETTLE ANY CLAIM RELATING HERETO. THE COMPANY AND HOLDER EACH 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 THE HOLDER 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. DISPUTE RESOLUTION. ANY DISPUTE AS TO THE DETERMINATION OF THE EXERCISE PRICE OR THE ARITHMETIC CALCULATION OF THE
WARRANT SHARES MUST BE RAISED BY REQUIRED HOLDERS OR THE COMPANY. IN THE CASE OF ANY SUCH DISPUTE, THE COMPANY SHALL SUBMIT THE DISPUTED DETERMINATIONS OR ARITHMETIC CALCULATIONS VIA FACSIMILE WITHIN TWO TRADING DAYS OF RECEIPT OF THE EXERCISE
NOTICE GIVING RISE TO SUCH DISPUTE, AS THE CASE MAY BE, TO THE HOLDER. IF THE REQUIRED HOLDERS AND THE COMPANY ARE UNABLE TO AGREE UPON SUCH DETERMINATION OR CALCULATION OF THE EXERCISE PRICE OR THE WARRANT SHARES WITHIN FIVE TRADING DAYS OF
SUCH DISPUTED DETERMINATION OR ARITHMETIC CALCULATION BEING SUBMITTED TO THE HOLDER, THEN THE COMPANY SHALL, WITHIN TWO TRADING 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 REQUIRED HOLDERS, SUCH APPROVAL NOT TO BE UNREASONABLY WITHHELD OR DELAYED OR (B) THE DISPUTED ARITHMETIC CALCULATION OF THE WARRANT SHARES TO THE COMPANY’S INDEPENDENT, OUTSIDE
ACCOUNTANT. THE COMPANY SHALL CAUSE 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 10 TRADING 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. THE EXPENSES OF THE
INVESTMENT BANK AND ACCOUNTANT WILL BE BORNE BY THE COMPANY UNLESS THE INVESTMENT BANK OR ACCOUNTANT DETERMINES THAT THE DETERMINATION OF THE EXERCISE PRICE OR THE ARITHMETIC CALCULATION OF THE WARRANT SHARES BY THE REQUIRED HOLDERS WAS INCORRECT,
IN WHICH CASE THE EXPENSES OF THE INVESTMENT BANK AND ACCOUNTANT WILL BE BORNE RATABLY BY THE HOLDER AND ANY OTHER HOLDERS OF WARRANTS BASED ON THE NUMBER OF WARRANT SHARES INTO WHICH THEIR RESPECTIVE WARRANTS ARE EXERCISABLE. ANY DETERMINATION OR
AGREEMENT BY REQUIRED HOLDERS AS TO A DISPUTED ITEM SHALL BE BINDING ON ALL CURRENT AND FUTURE HOLDERS OF WARRANTS. NOTHING IN THIS SECTION 13 SHALL BE DEEMED TO MODIFY OR MITIGATE THE TERMS OF SECTION 1(D) HEREOF.

each Dividend Payment Date on such Liquidation Value and all accrued but unpaid dividends thereon whether or not declared by the Board. Dividends shall be payable only when, as and if declared by the Board of Directors. If any Dividend Payment Date
would otherwise occur on a day that is not a Business Day, such Dividend Payment Date shall instead be (and any dividend payable on Series E on such Dividend Payment Date shall instead be payable on) the immediately succeeding Business Day with the
same force and effect as if made on such Dividend Payment Date. The amount of dividends payable on the Series E shall be computed on the basis of a 360-day year consisting of twelve 30-day months, and with respect to any date of determination that

Date shall be payable to holders of record of Series E as they appear on the stock register of the Corporation on the applicable record date, which shall be fixed by the Board of Directors and not more than 60 nor less than 10 days prior to such
Dividend Payment Date (each, a “Dividend Record Date”). Any such day that is a Dividend Record Date shall be a Dividend Record Date whether or not such day is a Business Day.

 (b) No Dividends on Junior Stock. So long as the Initial Purchaser and its Permitted
Transferees collectively hold at least 10% of the Series E issued to the Initial Purchaser at the closing of the transactions contemplated by the Securities Purchase Agreement (or if all such Series E is exchanged into Subordinated Notes pursuant to
the Securities Purchase Agreement, at least 10% of the aggregate principal amount outstanding of the Subordinated Notes), unless and until dividends have been declared and paid on the Series E for the then-current Dividend Period and past Dividend
Periods in cash, no dividends (other than dividends in shares of Junior Stock) may be declared or paid or set aside for payment, and no other distribution may be declared or made, upon Junior Stock; provided, however, that notwithstanding the
foregoing dividends or other distributions payable in cash upon Junior Stock may be declared or paid or set aside for payment in any then-current Dividend Period in which the semi-annual dividend amount payable on the Series E has been paid in cash
for the same then-current Dividend Period (whether or not any accrued or unpaid dividends have been declared or paid on the Series E for any other Dividend Period). So long as any Series E is outstanding, no Junior Stock may be redeemed, purchased
or otherwise acquired for any consideration (or any moneys be paid to or made available for a sinking fund for the redemption of any such shares) by the Corporation, except (A) by conversion into or exchange for Junior Stock (including any
shares of Common Stock surrendered to or withheld by the Corporation upon the exercise of warrants issuable for Common Stock), (B) for the repurchase of any shares of Common Stock held by employees or consultants of the Corporation upon
termination of their employment or services pursuant to agreements approved by the Corporation’s Board of Directors providing for such repurchase or (C) for any shares of Common Stock withheld by the Corporation to pay taxes upon the
granting or vesting of awards to any of its employees or service providers under any equity compensation plan of the Corporation approved by the Corporation’s Board of Directors or surrendered to or withheld by the Corporation to pay the
exercise price of any such awards. 
 (c) Participating Dividends. Subject to Section 4(a) and 4(b), in addition to the
dividends accruing on the Series E pursuant to Section 4(a), if the Corporation declares or pays a dividend or distribution on the Common Stock, whether such dividend or distribution is payable in cash, securities or other property, the
Corporation shall simultaneously declare and pay a dividend on the Series E on a pro rata basis with the Common Stock in an aggregate amount equal to such dividend or distribution payable with respect to the Participation Common Stock. 

Section 5. LIQUIDATION RIGHTS. 

(a) Voluntary or Involuntary Liquidation. In the event of any liquidation, dissolution or winding up of the affairs of the Corporation,
whether voluntary or involuntary, holders of Series E shall be entitled to receive for each share of Series E, out of the assets of the Corporation or proceeds thereof (whether capital or surplus) available for distribution to stockholders of the
Corporation, and after satisfaction of all liabilities and obligations to creditors of the Corporation, before any distribution of such assets or proceeds is made to or set aside for the holders of Common Stock and any other Junior Stock, payment in
full in an amount equal to the Liquidation Preference of each share of Series E. 

 (b) Partial Payment. If in any distribution described in Section 5(a), the assets of
the Corporation or proceeds thereof are not sufficient to pay the Liquidation Preferences in full to all holders of Series E as to such distribution, the amounts paid to the holders of Series E shall be paid pro rata in accordance with the
respective aggregate Liquidation Preferences of the holders of Series E. 
 (c) Participation with Common Stock; Residual
Distributions. If the Liquidation Preference has been paid in full to all holders of Series E, the holders of other stock of the Corporation shall be entitled to receive all remaining assets of the Corporation (or proceeds thereof) according to
their respective rights and preferences; provided, however, that in addition to and after the Liquidation Preference has been paid in full to all holders of Series E, the holders of Series E shall be entitled to participate with the holders of
Common Stock then outstanding, pro rata as a single class as if such holders of Series E held the Participation Common Stock, which amounts shall be paid to the holders of Series E pro rata in accordance with the respective aggregate Liquidation
Preferences of the shares of Series E held by each such holder of Series E. 
 (d) Merger, Consolidation and Sale of Assets Not
Liquidation. For purposes of this Section 5, the merger or consolidation of the Corporation with any other corporation or other entity, including a merger or consolidation in which the holders of Series E receive cash, securities or other
property for their shares, or the sale, lease or exchange (for cash, securities or other property) of all or substantially all of the assets of the Corporation, shall not constitute a liquidation, dissolution or winding up of the Corporation, but
shall be governed by Section 7. 
 Section 6. REDEMPTION. 

(a) Optional Redemption by Holders Subject to the provisions of this Section 6, at any time on or after the Optional Redemption
Date, each holder of Series E shall have the right to elect to have, out of funds legally available therefor, such holder’s shares of Series E redeemed, in whole at any time or in part from time to time, by the Corporation at a redemption price
per share equal to the Liquidation Preference of such share as of the redemption date. Any such redemption shall occur not more than 90 days following receipt by the Corporation of a written election notice from the electing holder. 

(b) Optional Redemption by the Corporation. The Corporation, at its option, may redeem, in whole at any time or in part from time to
time, the shares of Series E at the time outstanding, upon notice given as provided in Section 6 below, at a redemption price per share equal to the Liquidation Preference of such share as of the redemption date. 

(c) Notice of Redemption. Notice of every redemption of shares of Series E shall be given to the holders of record of the shares to be
redeemed at their respective last addresses appearing on the books of the Corporation. Such mailing shall be at least 30 days and not more than 60 days before the date fixed for redemption. Any notice mailed as provided in this Section 6(c)
shall be conclusively presumed to have been duly given, whether or not the holder receives such notice, but failure duly to give such notice by mail, or any defect in such notice or in the mailing thereof, to any holder of shares of Series E
designated for redemption shall not affect the validity of the proceedings for the redemption of any other shares of Series E. Each notice of redemption given to a holder shall state: (1) the redemption date; (2) the number of shares of

 
Series E to be redeemed and, if less than all the shares held by such holder are to be redeemed, the number of such shares to be redeemed from such holder; and (3) the redemption price. To
the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 6, the Corporation shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its
obligations under this Section 6 by virtue thereof. 
 (d) Partial Redemption. In case of any redemption pursuant to
Section 6(b) of part of the shares of Series E at the time outstanding, the shares to be redeemed shall be selected pro rata among holders of the Series E. 

(e) Effectiveness of Redemption. If notice of redemption has been duly given and if on or before the redemption date specified in the
notice all funds necessary for the redemption have been set aside for payment by the Corporation, then on and after the redemption date dividends shall cease to accrue on all shares so called for redemption, all shares so called for redemption shall
no longer be deemed outstanding and all rights with respect to such shares shall forthwith on such redemption date cease and terminate, except only the right of the holders thereof to receive the amount payable on such redemption, without interest.
Any funds unclaimed at the end of three years from the redemption date shall, to the extent permitted by law, be released to the Corporation, after which time the holders of the shares so called for redemption shall look only to the Corporation for

of the outstanding Series E (in the case of a redemption pursuant to Section 6(b)) and all other required approvals, including under any principal U.S. securities exchange or over-the-counter market on which the Common Stock is then listed for

the aggregate Liquidation Preference of such shares of Series E being redeemed in shares of Common Stock in lieu of cash at the redemption date; provided, that if the Corporation pays less than the total redemption price in shares of Common

writing not later than 10 days following receipt by such holder or holders of a notice of redemption from the Company in accordance 

 
with this Section 6. Any failure to deliver such consent or election within such 10-day period shall be deemed to be a waiver of such holder’s or holders’ right to consent or

 (iii) that any shares of Series E not tendered for payment pursuant to the Change
of Control Offer shall continue to accrue dividends and be redeemable in accordance with the terms hereof; 
 (iv) that,
unless the Corporation defaults in the payment of the Change of Control Price, all shares of Series E accepted for payment pursuant to the Change of Control Offer shall cease to accrue dividends on the Change of Control Payment Date; 

(v) that any holder of Series E represented by stock certificates, in connection with the acceptance of a Change of Control
Offer, shall be required to surrender such certificates representing shares of Series E to the Corporation or its designated agent at the address specified in the notice prior to the close of business on the Change of Control Payment Date; 

(vi) that any holder of a share of Series E shall be entitled to withdraw such election if the Corporation or its designated
agent receives, not later than the close of business on the Change of Control Payment Date, electronic transmission or letter setting forth the name of the holder of such shares of Series E, the number of shares of Series E such holder delivered for
purchase, and a statement that such holder is withdrawing its election to have such shares of Series E purchased; 

 (vii) the instructions that holders must follow in order to tender their shares
of Series E; and 
 (viii) the circumstances and relevant facts regarding such Change of Control. 

(c) On the Change of Control Payment Date, the Corporation shall, to the extent of funds legally available therefor and otherwise lawful,
accept for payment the shares of Series E tendered and not withdrawn pursuant to the Change of Control Offer. The Corporation shall promptly mail to each holder of shares of Series E so accepted payment (or pay in person any holder presenting itself
at the Corporation) in an amount equal to the purchase price for such shares calculated in accordance with the terms hereof, and the unpurchased shares of Series E surrendered, if any. 

(d) Notwithstanding any other provisions of this Section 7 (but subject to Section 7(d)(ii)), (i) subject to the Corporation
having obtained the prior written consent of the holders of a majority of the outstanding Series E and all other required approvals, including under any principal U.S. securities exchange or over-the-counter market on which the Common Stock is then
listed for trading, any redemption of shares of Series E pursuant to this Section 7 may be made, in lieu of some or all of the cash redemption payment, by the issuance of shares of Common Stock having an aggregate Common Stock Price equal to
the aggregate Change of Control Price of such shares of Series E being redeemed in shares of Common Stock in lieu of cash at the acceptance date; provided, that if the Corporation pays less than the total Change of Control Price in shares of
Common Stock, subject to receipt of the consent and approvals referenced above, such payment in shares of Common Stock shall be made pro rata to the holders of shares of Series E based upon the aggregate Change of Control Price of the shares
of Series E held by each holder and the remainder shall be paid in cash;, and (ii) the holders of a majority of the outstanding Series E shall be entitled in their sole discretion to require the Company to redeem the Participation Rights Value

ARTICLE II 
 REGISTRATION
RIGHTS 
 Section 2.01 Registration Effectiveness Deadline. Within nine (9) months following the Closing Date, the
Company shall prepare and file a registration statement under the Securities Act to permit the public resale of Registrable Securities then outstanding from time to time as permitted by Rule 415 (or any similar provision then in effect) under the
Securities Act with respect to all of the Registrable Securities (the “Registration Statement”). The Registration Statement filed pursuant to this Section 2.01(a) shall be on such appropriate registration form or forms of the
Commission as shall be selected by the Company so long as it permits the continuous offering of the Registrable Securities pursuant to Rule 415 (or any similar provision then in effect) under the Securities Act at then-prevailing market prices. The
Company shall use its commercially reasonable efforts to cause the Registration Statement to become effective on or as soon as practicable after the filing thereof. Any Registration Statement shall provide for the resale pursuant to any method or
combination of methods legally available to, and requested by, the Holders of any and all Registrable Securities covered by such Registration Statement. The Company shall use its commercially reasonable efforts to cause the Registration Statement
filed pursuant to this Section 2.01(a) to be effective, supplemented and amended to the extent necessary to ensure that it is available for the resale of all Registrable Securities by the Holders until the earlier of (x) the tenth
anniversary of the date hereof and (y) the date that all Registrable Securities covered by such Registration Statement have ceased to be Registrable Securities (the “Effectiveness Period”). The Registration Statement, when effective,
(including the documents incorporated therein by reference) shall comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and shall not contain an untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Registration Statement or documents incorporated therein by reference, in the
light of the circumstances under which a statement is made). As soon as practicable following the date that the Registration Statement becomes effective, but in any event within two (2) Business Days of such date, the Company shall provide the
Holders with written notice of the effectiveness of the Registration Statement. 
 (a) Failure to Go Effective. If the Registration
Statement required by Section 2.01(a) is not declared effective within twelve (12) months after the Closing Date, then the Purchaser shall be entitled to a payment (with respect to the Purchased Common Stock of such Purchaser), as
liquidated damages and not as a penalty, of 0.25% of the Liquidated Damages Multiplier per 30-day period, that shall accrue daily, for the first 30 days following the last day of the twelve-month 

  
 4 

 
period, increasing by an additional 0.25% of the Liquidated Damages Multiplier per 30-day period, that shall accrue daily, for each subsequent 30 days, up to a maximum of 1.00% of the Liquidated
Damages Multiplier per 30-day period (the “Liquidated Damages”). The Liquidated Damages payable pursuant to the immediately preceding sentence shall be payable within ten (10) Business Days after the end of each such 30-day
period. Notwithstanding anything to the contrary contained herein, in no event shall the aggregate of all Liquidated Damages payable by the Company hereunder exceed 3.0% of the Aggregate Purchase Price. Any Liquidated Damages shall be paid to the
Purchaser in immediately available funds; provided, however, if the Company certifies that it is unable to pay Liquidated Damages in cash because such payment would result in a breach of or constitute a default under a credit facility
or other debt instrument filed as exhibits to the Company SEC Documents, then the Company shall pay such Liquidated Damages using as much cash as is permitted without causing a breach of or default under such credit facility or other debt instrument
and shall pay the balance of any such Liquidated Damages in kind in the form of the issuance of Additional Common Stock. Upon any issuance of Additional Common Stock or Common Stock as Liquidated Damages, the Company shall promptly (i) prepare
and file an amendment to the Registration Statement prior to its effectiveness adding such Common Stock to such Registration Statement as additional Registrable Securities and (ii) prepare and file a supplemental listing application with the
NYSE (or such other national securities exchange on which the Common Stock are then-listed and traded) to list such Additional Common Stock. The determination of the number of shares of Common Stock to be issued as Liquidated Damages shall be equal
to the quotient of (i) the dollar amount of the balance of such Liquidated Damages due to such Purchaser divided by (ii) the volume-weighted average trading price of the Common Stock on the NYSE, or any other national securities exchange
on which the shares of Common Stock are then-traded, for the ten (10) trading days ending on the first trading day immediately preceding the date on which the Liquidated Damages payment is due. The accrual of Liquidated Damages to the Purchaser
shall cease at the earlier of (i) the Registration Statement becoming effective or (ii) when such Purchaser no longer holds Registrable Securities, and any payment of Liquidated Damages shall be prorated for any period of less than 30 days
in which the payment of Liquidated Damages ceases. If the Company is unable to cause a Registration Statement to go effective within twelve (12) months after the Closing Date as a result of an acquisition, merger, reorganization, disposition or
other similar transaction, then the Company may request a waiver of the Liquidated Damages, and the Purchaser may individually grant or withhold its consent to such request in its sole discretion. 

(b) Termination of Purchaser’s Rights. The Purchaser’s rights (and any transferee’s rights pursuant to
Section 2.11 of this Agreement) under this Section 2.01 shall terminate upon the termination of the Effectiveness Period. 

Section 2.02 Piggyback Rights. 

(a) Participation. If the Company proposes to file (i) a shelf registration statement other than the Registration Statement
contemplated by Section 2.01(a), (ii) a prospectus supplement to an effective shelf registration statement, other than the Registration Statement contemplated by Section 2.01(a) of this Agreement and Holders may be
included without the filing of a post-effective amendment thereto, or (iii) a registration statement, other than a shelf registration statement, in each case, for the sale of Common Stock in an Underwritten Offering

  
 5 

 
for its own account and/or another Person, then as soon as practicable following the engagement of counsel by the Company to prepare the documents to be used in connection with an Underwritten
Offering, the Company shall give notice (including, but not limited to, notification by electronic mail) of such proposed Underwritten Offering to each Holder (together with its Affiliates) holding at least $15 million of the then-outstanding
Registrable Securities (based on the Aggregate Purchase Price) and such notice shall offer such Holders the opportunity to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable
Securities”) as each such Holder may request in writing; provided, however, that if the Company has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will
have an adverse effect on the price, timing or distribution of the Common Stock in the Underwritten Offering, then (A) if no Registrable Securities can be included in the Underwritten Offering in the opinion of the Managing Underwriter, the
Company shall not be required to offer such opportunity to the Holders or (B) if any Registrable Securities can be included in the Underwritten Offering in the opinion of the Managing Underwriter, then the amount of Registrable Securities to be
offered for the accounts of Holders shall be determined based on the provisions of Section 2.02(b). Any notice required to be provided in this Section 2.02(a) to Holders shall be provided on a Business Day pursuant to
Section 3.01 hereof and receipt of such notice shall be confirmed by the Holder. Each such Holder shall then have two (2) Business Days (or one (1) Business Day in connection with any overnight or bought Underwritten Offering)
after notice has been delivered to request in writing the inclusion of Registrable Securities in the Underwritten Offering. If no written request for inclusion from a Holder is received within the specified time, each such Holder shall have no
further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, the Company shall determine for
any reason not to undertake or to delay such Underwritten Offering, the Company may, at its election, give written notice of such determination to the Selling Holders and, (x) in the case of a determination not to undertake such Underwritten
Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted
to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s
Registrable Securities in such Underwritten Offering by giving written notice to the Company of such withdrawal at or prior to the time of pricing of such Underwritten Offering. Any Holder may deliver written notice (an “Opt-Out
Notice”) to the Company requesting that such Holder not receive notice from the Company of any proposed Underwritten Offering; provided, however, that such Holder may later revoke any such Opt-Out Notice in writing. Following receipt
of an Opt-Out Notice from a Holder (unless subsequently revoked), the Company shall not be required to deliver any notice to such Holder pursuant to this Section 2.02(a) and such Holder shall no longer be entitled to participate in
Underwritten Offerings by the Company pursuant to this Section 2.02(a). The Holders indicated on Schedule A hereto as having opted out shall each be deemed to have delivered an Opt-Out Notice as of the date hereof. 

(b) Priority. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering advises the Company that the total
amount of Registrable Securities that the Selling Holders and any other Persons intend to include in such offering exceeds the number that can be sold in such offering without being likely to have an adverse effect on the price,

  
 6 

 
timing or distribution of the Common Stock offered or the market for the Common Stock, then the Common Stock to be included in such Underwritten Offering shall include the number of Registrable
Securities that such Managing Underwriter or Underwriters advises the Company can be sold without having such adverse effect, with such number to be allocated (i) first, to the Company and (ii) second, pro rata among the Selling Holders
who have requested participation in such Underwritten Offering and any other holder of securities of the Company having rights of registration that are neither expressly senior nor subordinated to the Registrable Securities (the “Parity
Securities”), provided, however, that in the case of a Requested Underwritten Offering pursuant to Section 2.04(b) in which the Purchaser is the Initiating Holder, such number shall be allocated (x) first, to the
Purchaser and (y) second, pro rata among the Selling Holders who have requested participation in such Underwritten Offering. The pro rata allocations for each Selling Holder who has requested participation in such Underwritten Offering shall be
the product of (a) the aggregate number of Registrable Securities proposed to be sold in such Underwritten Offering multiplied by (b) the fraction derived by dividing (x) the number of Registrable Securities owned on the Closing Date
by such Selling Holder by (y) the aggregate number of Registrable Securities owned on the Closing Date by all Selling Holders plus the aggregate number of Parity Securities owned on the Closing Date by all holders of Parity Securities that are
participating in the Underwritten Offering. 
 (c) Termination of Piggyback Registration Rights. Each Holder’s rights under this
Section 2.02 shall terminate upon such Holder (together with its Affiliates) ceasing to hold at least $15 million of Registrable Securities (based on the Aggregate Purchase Price). 

Section 2.03 Delay Rights. 

Notwithstanding anything to the contrary contained herein, the Company may, upon written notice to any Selling Holder whose Registrable
Securities are included in the Registration Statement or other registration statement contemplated by this Agreement, suspend such Selling Holder’s use of any prospectus which is a part of the Registration Statement or other registration
statement contemplated by this Agreement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Registration Statement or such other registration statement but may settle any previously made sales of
Registrable Securities) if (i) the Company is pursuing an acquisition, merger, reorganization, disposition, financing or other similar transaction and the Company determines in good faith that the Company’s ability to pursue or consummate
such a transaction would be materially adversely affected by any required disclosure of such transaction in the Registration Statement or such other registration statement or (ii) the Company has experienced some other material non-public
event, the disclosure of which at such time, in the good faith judgment of the Company, would materially adversely affect the Company; provided, however, in no event shall the Selling Holders be suspended from selling Registrable Securities
pursuant to the Registration Statement or such other registration statement for a period that exceeds an aggregate of 60 days in any 180-day period or 105 days in any 365-day period, in each case, exclusive of days covered by any lock-up agreement
executed by a Selling Holder in connection with any Underwritten Offering. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to the Selling Holders whose Registrable
Securities are included in the Registration Statement or other registration statement contemplated by this Agreement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit
registered sales of Registrable Securities as contemplated in this Agreement. 

  
 7 

 If (i) the Selling Holders shall be prohibited from selling their Registrable Securities
under the Registration Statement or other registration statement contemplated by this Agreement as a result of a suspension pursuant to the immediately preceding paragraph in excess of the periods permitted therein or (ii) the Registration
Statement or other registration statement contemplated by this Agreement is filed and declared effective but, during the Effectiveness Period, shall thereafter cease to be effective or fail to be usable for its intended purpose without being
succeeded within 30 Business Days by a post-effective amendment thereto, a supplement to the prospectus or a report filed with the Commission pursuant to Section 13(a), 13(c), 14 or l5(d) of the Exchange Act, then, until the suspension is
lifted or a post-effective amendment, supplement or report is filed with the Commission, but not including any day on which a suspension is lifted or such amendment, supplement or report is filed and declared effective, if applicable, the Company
shall pay the Selling Holders an amount equal to the Liquidated Damages, following the earlier of (x) the date on which the suspension period exceeded the permitted period and (y) the thirty-first (31st) Business Day after the
Registration Statement or other registration statement contemplated by this Agreement ceased to be effective or failed to be useable for its intended purposes, as liquidated damages and not as a penalty (for purposes of calculating Liquidated
Damages, the date in (x) or (y) above shall be deemed the “last day of the twelve-month period,” as used in the definition of Liquidated Damages). For purposes of this paragraph, a suspension shall be deemed lifted on the date
that notice that the suspension has been terminated is delivered to the Selling Holders. Liquidated Damages pursuant to this paragraph shall cease to accrue upon the Purchased Common Stock held of record by such Holder becoming eligible for resale
without restriction and without the need for current public information under any section of Rule 144 (or any similar provision then in effect) under the Securities Act, and any payment of Liquidated Damages shall be prorated for any period of less
than 30 days in which the payment of Liquidated Damages ceases. 
 Section 2.04 Underwritten Offerings. 

(a) General Procedures. Subject to Section 2.04(b), in connection with any Underwritten Offering under this Agreement, the
Company shall be entitled to select the Managing Underwriter or Underwriters. In connection with an Underwritten Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder and the Company shall be obligated
to enter into an underwriting agreement that contains such representations, covenants, indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of securities. No Selling Holder may
participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and
other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and
for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to
its obligations. No Selling Holder shall be required to make any representations or warranties to or 

  
 8 

 
agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Selling Holder, its authority to enter into such underwriting agreement and to
sell, and its ownership of, the securities being registered on its behalf, its intended method of distribution and any other representation required by Law. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder may
elect to withdraw therefrom by notice to the Company and the Managing Underwriter; provided, however, that such withdrawal must be made up to and including the time of pricing of such Underwritten Offering. No such withdrawal or abandonment
shall affect the Company’s obligation to pay Registration Expenses. The Company’s management may but shall not be required to participate in a roadshow or similar marketing effort in connection with any Underwritten Offering. 

(b) Demand Rights. 

(i) Any Holder shall have the option and right, exercisable by delivering written notice to the Company of its intention to
distribute Registrable Securities by means of an Underwritten Offering (an “Underwritten Offering Notice”), to require the Company, pursuant to the terms of and subject to the limitations of this Agreement, to effectuate a
distribution of any or all of its Registrable Securities by means of an Underwritten Offering pursuant to an effective Registration Statement covering such Registrable Securities (a “Requested Underwritten Offering”);
provided, that the Registrable Securities of such Initiating Holder requested to be included in such Requested Underwritten Offering have an aggregate value of at least $15 million as of the date of such Underwritten Offering Notice. The
Underwritten Offering Notice must set forth the number of Registrable Securities that the Initiating Holder intends to include in such Requested Underwritten Offering. The Managing Underwriter of a Requested Underwritten Offering shall be designated
by the Initiating Holder; provided, however, that such designated Managing Underwriter shall be reasonably acceptable to the Company. Any Requested Underwritten Offering shall constitute an Underwritten Offering of the Initiating
Holder for purposes of Section 2.04(b)(ii). 
 (ii) Subject to the other limitations contained in this Agreement,
the Company shall not be obligated hereunder to effect more than one (1) Requested Underwritten Offering per calendar year, or more than four (4) Requested Underwritten Offerings in the aggregate, for which the Purchaser (or any transferee
thereof in accordance with Section 2.11) is the Initiating Holder. 
 Section 2.05 Sale Procedures. In connection
with its obligations under this Article II, the Company will, as expeditiously as possible: 
 (a) prepare and file with the Commission such
amendments and supplements to the Registration Statement and the prospectus and any prospectus supplement used in connection therewith as may be necessary to keep the Registration Statement effective for the Effectiveness Period and as may be
necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by the Registration Statement; 

  
 9 

 (b) if a prospectus or prospectus supplement will be used in connection with the marketing of an
Underwritten Offering from the Registration Statement and the Managing Underwriter at any time shall notify the Company in writing that, in the sole judgment of such Managing Underwriter, inclusion of detailed information to be used in such
prospectus or prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, the Company shall use its commercially reasonable efforts to include such information in such prospectus or
prospectus supplement; 
 (c) furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing the
Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and
each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its
plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Registration Statement or such other registration statement or supplement or
amendment thereto, and (ii) such number of copies of the Registration Statement or such other registration statement and the prospectus and any prospectus supplement included therein and any supplements and amendments thereto as such Selling
Holder may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration Statement or other registration statement; 

(d) if applicable, use its commercially reasonable efforts to register or qualify the Registrable Securities covered by the Registration
Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering, the Managing Underwriter, shall reasonably
request; provided, however, that the Company will not be required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of
process in any such jurisdiction where it is not then so subject; 
 (e) promptly notify each Selling Holder, at any time when a prospectus
relating thereto is required to be delivered by any of them under the Securities Act, of (i) the filing of the Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or prospectus supplement
to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any such other registration statement or any post-effective amendment thereto, when the same has become effective; and
(ii) the receipt of any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to the Registration Statement or any such
other registration statement or any prospectus or prospectus supplement thereto; 
 (f) promptly notify each Selling Holder of (i) the
happening of any event as a result of which the prospectus or prospectus supplement contained in the Registration Statement or any other registration statement contemplated by this Agreement, as then in effect, includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein or 

  
 10 

 
necessary to make the statements therein not misleading (in the case of any prospectus or prospectus supplement contained therein, in the light of the circumstances under which such statement is
made); (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any other registration statement contemplated by this Agreement, or the knowledge of the initiation
of any proceedings for that purpose; or (iii) the receipt by the Company of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any
jurisdiction. Following the provision of such notice, the Company agrees, subject to Section 2.03 of this Agreement, to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate
action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of
the circumstances then existing and to take such other commercially reasonable action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto; 

(g) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal
letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable
Securities; 
 (h) in the case of an Underwritten Offering, furnish upon request, (i) an opinion of counsel for the Company dated the
date of the closing under the underwriting agreement and (ii) a “comfort” letter, dated the pricing date of such Underwritten Offering and a letter of like kind dated the date of the closing under the underwriting agreement, in each
case, signed by the independent public accountants who have certified the Company’s financial statements included or incorporated by reference into the applicable registration statement, and each of the opinion and the “comfort”
letter shall be in customary form and covering substantially the same matters with respect to such registration statement (and the prospectus and any prospectus supplement included therein) as have been customarily covered in opinions of
issuer’s counsel and in accountants’ letters delivered to the underwriters in Underwritten Offerings of securities by the Company and such other matters as such underwriters and Selling Holders may reasonably request; 

(i) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make
available to its security holders, as soon as reasonably practicable, an earnings statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder; 

(j) make available to the appropriate representatives of the Managing Underwriter and Selling Holders access to such information and Company
personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided, that the Company need not disclose any non-public information to any such representative unless and until
such representative has entered into a confidentiality agreement with the Company; 

  
 11 

 (k) cause all such Registrable Securities registered pursuant to this Agreement to be listed on
each securities exchange or nationally recognized quotation system on which similar securities issued by the Company are then listed; 
 (l)
use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable
the Selling Holders to consummate the disposition of such Registrable Securities; 
 (m) provide a transfer agent and registrar for all
Registrable Securities covered by such registration statement not later than the effective date of such registration statement;

(o) if requested by a Selling Holder, (i) incorporate in a prospectus or prospectus supplement or post-effective amendment to the
Registration Statement or any other registration statement contemplated by this Agreement such information as such Selling Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including
information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering and (ii) make all
required filings of such prospectus or prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus or prospectus supplement or post-effective amendment. 

The Company shall not name a Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act in any registration statement
without such Holder’s consent. If the staff of the Commission requires the Company to name any Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act, or the Company deems it required, on the written advice of
counsel, to name any Holder, and such Holder does not consent thereto, then such Holder’s Registrable Securities shall not be included on the Registration Statement (or any other registration statement contemplated by this Agreement), such
Holder shall no longer be entitled to receive Liquidated Damages under this Agreement with respect thereto, the Company shall have no further obligations hereunder with respect to Registrable Securities held by such Holder. 

Each Selling Holder, upon receipt of notice from the Company of the happening of any event of the kind described in
subsection (f) of this Section 2.05, shall forthwith discontinue offers and sales of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of
the supplemented or amended prospectus or prospectus supplement contemplated by subsection (f) of this Section 2.05 or until it is advised in writing by the Company that the use of the prospectus or prospectus supplement may
be resumed and has received copies of any additional or supplemental filings incorporated by reference in the prospectus or prospectus supplement, and, if so directed by the Company, such Selling Holder will, or will request the Managing
Underwriter(s), if any, to deliver to the Company (at the Company’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus or prospectus supplement
covering such Registrable Securities current at the time of receipt of such notice. 

  
 12 

 Section 2.06 Cooperation by Holders. The Company shall have no obligation to include
in the Registration Statement, or in an Underwritten Offering pursuant to Section 2.02(a), Registrable Securities of a Holder who has failed to timely furnish such information that the Company determines, after consultation with its counsel, is
reasonably required in order for the registration statement or prospectus or prospectus supplement, as applicable, to comply with the Securities Act. 

Section 2.07 Restrictions on Public Sale by Holders of Registrable Securities. Each Holder of Registrable Securities agrees, if
requested by the underwriters of an Underwritten Offering, to enter into a customary letter agreement with such underwriters providing such Holder will not effect any public sale or distribution of Registrable Securities during the 45 calendar day
period beginning on the date of a prospectus or prospectus supplement filed with the Commission with respect to the pricing of any Underwritten Offering, provided that (i) the duration of the foregoing restrictions shall be no longer
than the duration of the shortest restriction generally imposed by the underwriters on the Company or the officers, directors or any other Affiliate of the Company on whom a restriction is imposed and (ii) the restrictions set forth in this
Section 2.07 shall not apply to any Registrable Securities that are included in such Underwritten Offering by such Holder. In addition, this Section 2.07 shall not apply to any Holder that is not entitled to participate in such
Underwritten Offering, whether because such Holder delivered an Opt-Out Notice prior to receiving notice of the Underwritten Offering or because such Holder holds less than $15 million of the then-outstanding Registrable Securities (based on the
Aggregate Purchase Price). 
 Section 2.08 Expenses. 

(a) Expenses. The Company will pay all reasonable Registration Expenses as determined in good faith, including, in the case of an
Underwritten Offering, whether or not any sale is made pursuant to such Underwritten Offering. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any sale of its Registrable Securities hereunder. In addition,
except as otherwise provided in Section 2.09 hereof, the Company shall not be responsible for professional fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder. 

(b) Certain Definitions. “Registration Expenses” means all expenses incident to the Company’s performance under
or compliance with this Agreement to effect the registration of Registrable Securities on the Registration Statement pursuant to Section 2.01(a) or an Underwritten Offering covered under this Agreement, and the disposition of such
Registrable Securities, including, without limitation, all registration, filing, securities exchange listing and NYSE fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of
the Financial Industry Regulatory Authority, fees of transfer agents and registrars, all word processing, duplicating and printing expenses, any transfer taxes and the fees and disbursements of counsel and independent public accountants for the
Company, including the expenses of any special audits or “comfort” letters required by or incident to such performance and compliance. “Selling Expenses” means all underwriting fees, discounts and selling commissions or
similar fees or arrangements allocable to the sale of the Registrable Securities. 

  
 13 

 Section 2.09 Indemnification. 

(a) By the Company. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement,
the Company will indemnify and hold harmless each Selling Holder thereunder, its Affiliates that own Registrable Securities and their respective directors, officers, employees and agents and each Person, if any, who controls such Selling Holder
within the meaning of the Securities Act and the Exchange Act, and its directors, officers, employees or agents (collectively, the “Selling Holder Indemnified Persons”), against any losses, claims, damages, expenses or liabilities
(including reasonable attorneys’, accountants’ and experts’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified Person may become subject under the Securities Act,
the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case
of any prospectus or prospectus supplement, in the light of the circumstances under which such statement is made) contained in the Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus,
preliminary prospectus supplement, free writing prospectus or final prospectus or prospectus supplement contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus or prospectus supplement, in the light of the circumstances under which they were made) not misleading, and will reimburse each such
Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that the Company will not be liable in any
such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder Indemnified
Person in writing specifically for use in the Registration Statement or such other registration statement contemplated by this Agreement, any preliminary prospectus, preliminary prospectus supplement, free writing prospectus, or final prospectus or
prospectus supplement contained therein, or any amendment or supplement thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder Indemnified Person, and shall survive
the transfer of such securities by such Selling Holder. 
 (b) By Each Selling Holder. Each Selling Holder agrees severally and not
jointly to indemnify and hold harmless the Company, its directors, officers, employees and agents and each Person, if any, who controls the Company within the meaning of the Securities Act or of the Exchange Act, and its directors, officers,
employees and agents, to the same extent as the foregoing indemnity from the Company to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for
inclusion in the Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, preliminary prospectus supplement, free writing prospectus or final prospectus or prospectus supplement contained
therein, or any amendment or supplement thereof; provided, however, that the liability of each 

  
 14 

 
Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities
giving rise to such indemnification. 
 (c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the
commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party
shall not relieve it from any liability that it may have to any indemnified party other than under this Section 2.09. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement
thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.09 for any legal expenses subsequently incurred by
such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense
or employ counsel reasonably acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may
be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the
indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate
counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought against any
indemnified party with respect to which such indemnified party is entitled to indemnification hereunder without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, does not include any admission
of culpability or wrongdoing on the part of, and includes a complete and unconditional release from all liability of, the indemnified party. 

(d) Contribution. If the indemnification provided for in this Section 2.09 is held by a court or government agency of
competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount
paid or payable by such indemnified party as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of such indemnified party on the other in connection with the
statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute an aggregate amount in excess of the dollar
amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party on the one hand and the indemnified party on the
other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by

  
 15 

 
such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be
just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an
indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any
Loss that is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent
misrepresentation. 
 (e) Other Indemnification. The provisions of this Section 2.09 shall be in addition to any other
rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise. 

Section 2.10 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission
that may permit the sale of the Registrable Securities to the public without registration, the Company agrees to: 
 (a) use its
commercially reasonable efforts to make and keep public information regarding the Company available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times from and after the date hereof; 

(b) use its commercially reasonable efforts to file with the Commission in a timely manner all reports and other documents required of the
Company under the Securities Act and the Exchange Act at all times from and after the date hereof; and 
 (c) so long as a Holder owns any
Registrable Securities, furnish (i) to the extent accurate, forthwith upon request, a written statement of the Company that it has complied with the reporting requirements of Rule 144 under the Securities Act, and (ii) unless otherwise
available via EDGAR, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or
regulation of the Commission allowing such Holder to sell any such securities without registration. 
 Section 2.11 Transfer or
Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities granted to the Purchaser by the Company under this Article II may be transferred or assigned by any Purchaser only if such transfer would be
permitted for a transfer of “Securities” (as defined in the Securities Purchase Agreement) pursuant to Section 7.05 of the Securities Purchase Agreement; provided, however, that (a) unless the transferee or assignee is an
Affiliate of, and after such transfer or assignment continues to be an Affiliate of, the Purchaser, the amount of Registrable Securities transferred or assigned to such transferee or assignee shall represent at least $15 million of Registrable
Securities (based on the Aggregate Purchase Price), (b) the Company is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee or assignee and identifying the securities with respect
to which such registration rights are being transferred or assigned, (c) each such transferee or assignee assumes in writing responsibility for 

  
 16 

 
its portion of the obligations of the Purchaser under this Agreement and (d) the transferor or assignor is not relieved of any obligation or liabilities hereunder arising out of events
occurring prior to such transfer. 
 Section 2.12 Limitation on Subsequent Registration Rights. From and after the date hereof,
the Company shall not, without the prior written consent of the Holders of a majority of the Registrable Securities, enter into any agreement with any current or future holder of any securities of the Company that would allow such current or future
holder to require the Company to include securities in any registration statement filed by the Company on a basis other than pari passu with, or expressly subordinate to the rights of, the Holders of Registrable Securities hereunder.

 Section 3.11 Entire Agreement. This Agreement, the Securities
Purchase Agreement and the other agreements and documents referred to herein and therein are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of

or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of the Purchaser or any former, current or future director, officer, employee, agent, general or limited partner, manager, member,
stockholder or Affiliate of any of the foregoing, as such, for any obligations of the Purchaser under this Agreement or any documents or instruments delivered in connection herewith or therewith or for any claim based on, in respect of or by reason

 19 

 
permitted under this Agreement. Nothing contained herein, and no action taken by the Purchaser pursuant thereto, shall be deemed to constitute the Purchaser (and its permitted transferees or

FORM OF OPINION OF COMPANY COUNSEL 

  
 F-1 

 December 4, 2015 

LSB Funding LLC 
 350 Park Avenue, 14th Floor 

New York, NY 10022 
 Ladies and Gentlemen: 

This opinion is provided to you pursuant to Section 2.04(a)(viii) of the Securities Purchase Agreement, dated December 4, 2015, (the
“Securities Purchase Agreement”), by and among LSB Industries, Inc., a Delaware corporation (the “Company”), and LSB Funding LLC, a Delaware limited liability company (the
“Purchaser”), and, solely for purposes of Section 7.13 thereof, Security Benefit Corporation, a Kansas corporation (“Security Benefit”), pursuant to which the Purchaser has agreed to purchase from
the Company (i) 210,000 shares of the Company’s Series E Cumulative Redeemable Class C Preferred Stock, no par value per share (the “Series E Preferred Shares”), (ii) one share of the Company’s Series F
Redeemable Class C Preferred Stock, no par value per share (the “Series F Preferred Share”), and (iii) warrants (the “Warrants” and, collectively with the Series E Preferred Shares and the Series
F Preferred Share, the “Securities”) to purchase 4,103,746 shares of the Company’s common stock, $0.10 par value per share (the “Common Stock”), on the terms and for the purposes set forth in the
Securities Purchase Agreement. Any capitalized term used in this opinion and not defined herein shall have the meaning ascribed to such term in the Securities Purchase Agreement. 

We have acted as counsel to the Company in connection with the offer and sale by the Company of the Securities. In connection with the
opinions set forth below, we have examined and relied upon the following: 
 (a) a copy of the Restated Certificate of
Incorporation of the Company, as amended or restated as of the date hereof (the “Certificate”); 

(b) a copy of the Amended and Restated Bylaws of the Company, as amended or restated as of the date hereof (the
“Bylaws”); 
 (c) evidence of issuance by book entry (in the form of a screen shot of the transfer
agent’s records) of the Series E Preferred Shares; 
 (d) the Certificate of Designations setting forth the rights,
preferences, privileges and restrictions applicable to the Series E Preferred Shares, executed by the Company, dated as of December 4, 2015, as filed with the Secretary of State of the State of Delaware (the “Series E
COD”); 
 (e) evidence of issuance by book entry (in the form of a screen shot of the transfer agent’s
records) of the Series F Preferred Share; 
 (f) the Certificate of Designations setting forth the rights, preferences,
privileges and restrictions applicable to the Series F Preferred Share, executed by the Company, dated as of December 4, 2015, as filed with the Secretary of State of the State of Delaware (the “Series F COD”); 

 (g) an original Warrant, executed by the Company, dated as of the date hereof
(the “Warrant”); 
 (h) copies of certain resolutions duly adopted on December 2, 2015 by the
board of directors of the Company; 
 (i) an executed copy of the Securities Purchase Agreement; 

(j) an executed copy of the Registration Rights Agreement, dated as of the date hereof, by and between the Company and the
Purchaser (the “Registration Rights Agreement”); 
 (k) an executed copy of the Board Representation
and Standstill Agreement, dated as of the date hereof, by and between the Company, the Purchaser, Security Benefit, Todd Boehly, and the Golsen Holders party thereto (the “Purchaser Board Representation and Standstill
Agreement”); 
 (l) the Renewed Rights Agreement of the Company, dated as of December 2, 2008; 

(m) the Amendment to Renewed Rights Agreement, dated as of December 4, 2015 (the “Rights Agreement
Amendment”); 
 (n) copies of letters or certificates of recent dates received by us from public officials in
the State of Delaware as to the valid existence and good standing of the Company; 
 (o) copies of all certificates and other
documents delivered as of the date hereof at the closing of the purchase and sale of the Securities under the Securities Purchase Agreement; and 

(p) such other documents, records, certificates, instruments and opinions as we have deemed necessary or appropriate in order
to deliver the opinions expressed below. 
 The term “Transaction Documents” is used in this letter to refer collectively to the
Securities Purchase Agreement, the Registration Rights Agreement, the Warrant, the Purchaser Board Representation and Standstill Agreement and the Rights Agreement Amendment. As used in this letter, the terms “to our knowledge” and
“known to us” each means the actual knowledge of the partners at our firm who have devoted substantial time to representing the Company in connection with the transactions contemplated by the Transaction Documents. 

 Based on the foregoing, and subject to the qualifications and limitations set forth herein, we
are of the opinion that: 
 1. The Company is validly existing and is in good standing as a corporation under the Delaware General
Corporation Law, as amended (the “DGCL”). The Company has full corporate power and authority necessary to own or lease its properties and to conduct its business, in each case in all material respects as described in the
Company SEC Documents. 
 2. The Company has the requisite corporate power and authority to execute and deliver the Transaction Documents,
and to perform its obligations thereunder. 
 3. Each of the Transaction Documents has been duly authorized, executed and delivered by the
Company and is a valid and legally binding agreement of the Company, enforceable against the Company in accordance with its terms, except that the enforcement thereof may be limited (a) by bankruptcy, insolvency, reorganization, moratorium or
other similar laws now or hereafter in effect relating to or affecting creditors’ rights and remedies generally, (b) by the effect of general principles of equity (regardless of whether such enforcement is considered in a proceeding at law
or in equity) and an implied covenant of good faith and fair dealing and (c) as any rights to indemnity or contribution hereunder may be limited by federal or state securities laws and public policy considerations. 

4. The Series E Preferred Shares and the Series F Preferred Share to be issued and sold by the Company to the Purchaser have been duly
authorized by the Company and, when issued and delivered against payment therefor as provided in accordance with the Securities Purchase Agreement, will be validly issued, fully paid and nonassessable. 

5. The Common Stock issuable upon exercise of the Warrants and redemption of the Participation Rights Value (as defined in the Series E COD)
(collectively, the “Additional Common Stock”) has been duly authorized by the Company and, when issued upon exercise of the Warrants or redemption of the Participation Rights Value, respectively, in accordance with the terms
of the Warrants and the Series E COD, respectively, will be validly issued, fully paid and nonassessable. 
 6. To our knowledge, except as
identified or provided for in the Transaction Documents, there are no preemptive rights or other rights to subscribe for or to purchase any equity interests in the Company. To our knowledge, the offering, issuance or sale of the Securities as
contemplated by the Securities Purchase Agreement does not give rise to any rights for or relating to the registration of any Securities or other securities of the Company other than rights as provided in the Registration Rights Agreement. 

7. The execution and delivery by the Company of each Transaction Document does not, and the performance by the Company of its obligations
thereunder will not: (i) violate the Certificate or the Bylaws; (ii) result in the creation or imposition of any lien, charge or encumbrance upon the Company pursuant to the terms or provisions of, or constitute a breach or violation of,
or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under, or give any other party a right to terminate any of its obligations under, or result in the acceleration under, the Specified Contracts

 10. Assuming the accuracy of the representations and warranties of the Purchaser and the Company contained in the Securities
Purchase Agreement, the offer, issuance and sale of the Securities by the Company to the Purchaser solely in the manner contemplated by the Securities Purchase Agreement are exempt from the registration requirements of the Securities Act; provided
that we express no opinion as to any subsequent sale. 
 In rendering the opinions expressed herein, we have: 

(A) relied, without independent investigation or verification, with respect to matters of fact upon which the advice in this
letter is based, upon certificates of officers of the Company and upon information obtained from public officials and from officers and other representatives of the Company and upon the representations of the Company set forth in the Securities
Purchase Agreement; 
 (B) assumed that all documents submitted to us as originals are authentic, that all copies submitted
to us conform to the originals thereof, and that the signatures on all documents examined by us are genuine; 
 (C) assumed
that each certificate from governmental officials reviewed by us is accurate, complete and authentic, and all official public records are accurate and complete; and 

(D) with respect to the opinions expressed in paragraph 1 above as to valid existence and good standing of the Company, relied
solely on certificates, dated as of recent dates, from officials of the State of Delaware and/or written facsimile advice of recent dates from CT Corporation. 

Our opinion is limited to matters governed by the federal laws of the United States of America to the extent specifically referred to herein,
the DGCL and the contract law of the State of New York, in each case as currently in effect (“Applicable Law”), and we express no opinion 

 
as to the law of any other jurisdiction. With respect to the opinion set forth in paragraph (3) above, (i) we have assumed, with your consent and without any independent investigation
on our part, that the internal laws of the State of Delaware are the same as the internal laws of the State of New York and (ii) we express no opinion as to the enforceability of any provisions relating to: (a) any failure to comply with
requirements concerning notices, relating to delay or omission to enforce rights or remedies or purporting to waive or affect rights, claims, defenses or other benefits to the extent that any of the same cannot be waived or so affected under
applicable law; (b) indemnities or exculpation from liability to the extent prohibited by federal or state laws and the public policies underlying those laws or that might require indemnification for, or exculpation from liability on account
of, gross negligence, willful misconduct, unlawful acts, fraud or illegality of an indemnified or exculpated party; (c) requirements that all amendments, waivers and terminations be in writing or the disregard of any course of dealing between
the parties; or (d) an attempt to confer subject matter jurisdiction in respect of bringing suit, enforcement of judgments or otherwise on any federal or state court. Except as expressly set forth in paragraphs (9) and (10), we are not
providing any opinion with respect to any federal or state securities laws. 
 This opinion letter is furnished to you solely for your
benefit pursuant to Section 2.04(a)(viii) of the Securities Purchase Agreement. This letter and the opinions expressed and the statements made herein may not be used or relied upon by you for any other purpose and may not be used or relied upon
for any purpose by any other person or entity without our prior written consent. Except for the use permitted herein, this opinion letter is not to be quoted or reproduced in whole or in part or otherwise referred to in any manner nor is it to be
filed with any governmental agency or delivered to any other person without our prior written consent. This opinion letter speaks as of its date, and we undertake no (and hereby disclaim any) obligation to update this letter or the opinions
expressed or the statements made herein. 
 Very truly yours,
