In connection with the Board Representation Rights Transfer and for other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged by each of LSB Funding and the Company, each of the Company, LSB Funding, Security Benefit Corporation, Boehly and the Golsen Holders hereby agree, in accordance with

Section 4(f) of the Board Representation and Standstill Agreement, to the following amendments to the Board Representation and Standstill Agreement, which constitute a written amendment for purposes thereof:

For so long as the Board consists of nine (9) or fewer Directors, from and after the Closing and until the Board Designation Termination Date, the Purchaser shall be entitled to designate up to two (2) Purchaser Designated Directors pursuant to this Section 1; provided, however, that, from and after the redemption in full of all of the Acquired Series E-1 Preferred Stock held by the Purchaser and its Permitted Transferees (the “Redemption Termination Date”), so long as the Purchaser and its Permitted Transferees, collectively, continue to beneficially own at least 10% (but less than 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 one (1) Purchaser Designated Director and the Company and Board shall take all actions necessary or advisable to effect the foregoing provision. For so long as the Board consists of ten (10) or more Directors, 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 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 and the Company and Board shall take all actions necessary or advisable to effect the foregoing provision. 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 570,282 shares of Common Stock (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 and the Company and Board shall take all actions necessary and advisable to effect the foregoing provision. 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 570,282 shares of 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.

“Affiliate” means, with respect to any Person, any other Person that directly or indirectly through one or more intermediaries controls, is controlled by or is under common control with, the Person in question. As used herein, the term “control” means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of a Person, whether through ownership of voting securities, by contract or otherwise. For the avoidance of doubt, for purposes of this Agreement, the Company, on the one hand, and the Purchaser, on the other, shall not be considered Affiliates.
