(a) The parties hereby acknowledge and agree that the rights of the parties hereunder are special, unique and of extraordinary character, and that if any party refuses or otherwise fails to act, or to cause its Affiliates to act, in accordance with the provisions of this Agreement, such refusal or failure would result in irreparable injury to the Company or the Investor as the case may be, the exact amount of which would be difficult to ascertain or estimate and the remedies at law for which would not be reasonable or adequate compensation. Accordingly, if any party refuses or otherwise fails to act, or to cause its Affiliates to act, in accordance with the provisions of this Agreement, then, in addition to any other remedy which may be available to any damaged party at law or in equity, such damaged party will be entitled to seek specific performance and injunctive relief, without posting bond or other security, and without the necessity of proving actual or threatened damages, which remedy such damaged party will be entitled to seek in any court of competent jurisdiction.

2.7 Indemnification. In the event any Registrable Securities are included in a Registration Statement under this Agreement:

(a) The Company shall indemnify and hold harmless the Investor, any underwriter (as defined in the Securities Act) for the Investor and each Person, if any, who controls the Investor or underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and the officers, directors, owners, agents and employees of such controlling Persons, against any and all losses, claims, damages or liabilities (joint or several) to which they may become subject under any securities Laws including, without limitation, the Securities Act, the Exchange Act, or any other statute or common law of the United States or any other country or political subdivision thereof, or otherwise, including the amount paid in settlement of any litigation commenced or threatened (including any amounts paid pursuant to or in settlement of claims made under the indemnification or contribution provisions of any underwriting or similar agreement entered into by the Investor in connection with any offering or sale of securities covered by this Agreement), and shall promptly reimburse them, as and when incurred, for any legal or other expenses incurred by them in connection with investigating any claims and defending any actions, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (each, a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in or incorporated by reference into such Registration Statement, including any preliminary prospectus or final prospectus contained therein or any free writing prospectus or any amendments or supplements thereto, or in any offering memorandum or other offering document relating to the offering and sale of such securities, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading or (iii) any violation or alleged violation by the Company (or any of its agents or Affiliates) of the Securities Act, the Exchange Act, any state securities Law, or any rule or regulation promulgated under any state securities Law, in each case arising from such Registration Statement; provided, however, the Company shall not be liable in any such case for any such loss, claim, damage, liability or action to the extent that it (A) arises out of or is based upon a Violation which occurs solely in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by the Investor; or (B) is caused by the Investor’s disposition of Registrable Securities after notice from the Company pursuant to Section 2.4(g) during any period during which the Investor is obligated to discontinue any disposition of Registrable Securities as a result of any stop order suspending the effectiveness of any Registration Statement or prospectus with respect to Registrable Securities. The Company shall pay, as incurred, any legal or other expenses reasonably incurred by any Person intended to be indemnified pursuant to this Section 2.7(a), in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 2.7(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed.

(b) The Investor shall indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the Registration Statement, each Person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and the officers, directors, owners, agents and employees of such controlling Persons, any underwriter, any other Investor selling securities in such Registration Statement and any controlling Person of any such underwriter or other Investor, against any losses, claims, damages or liabilities (joint or several) to which any of the foregoing Persons may become subject, under liabilities (or actions in respect thereto) which arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation: (i) arises out of or is based upon a Violation which occurs solely in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by the Investor; or (ii) is caused by the Investor’s disposition of Registrable Securities after notice from the Company pursuant to Section 2.4(g) during any period during which the Investor is obligated to discontinue any disposition of Registrable Securities as a result of any stop order suspending the effectiveness of any Registration Statement or prospectus with respect to Registrable Securities. The Investor shall pay, as incurred, any legal or other expenses reasonably incurred by any Person intended to be indemnified pursuant to this Section 2.7(b), in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this Section 2.7(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without consent of the Investor, which consent shall not be unreasonably withheld.

(c) Promptly after receipt by an indemnified party under this Section 2.7 of notice of the commencement of any action (including any action by a Governmental Authority), such indemnified party shall, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.7, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the reasonable fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial in a material respect to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.7, but the omission so to deliver written notice to the indemnifying party shall not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.7.

(d) In order to provide for just and equitable contribution to joint liability in any case in which a claim for indemnification is made pursuant to this Section 2.7 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 2.7 provided for indemnification in such case, the Company and the Investor shall contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in proportion to the relative fault of the Company, on the one hand, and the Investor, on the other hand; provided, however, that in any such case, 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 was not guilty of such fraudulent misrepresentation; provided further, however, that in no event shall any contribution under this Section 2.7(d) on the part of any Investor exceed the net proceeds received by the Investor from the sale of Registrable Securities giving rise to such contribution obligation, except in the case of willful misconduct or fraud by the Investor.

(e) The obligations of the Company and the Investor under this Section 2.7 shall survive the completion of any offering of Registrable Securities in a Registration Statement under this Agreement and otherwise.

2.8 SEC Reports. With a view to making available to the Investor the benefits of Rule 144 under the Securities Act and any other rule or regulation of the SEC that may at any time permit the Investor to sell Registrable Securities of the Company to the public without registration, the Company agrees to at any time that it is a reporting company under Section 13 or 15(d) of the Exchange Act:

(a) file with the SEC in a timely manner all reports and other documents required of the Company under the Exchange Act; and

(b) furnish to the Investor, so long as the Investor owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing the Investor of any rule or regulation of the SEC (exclusive of Rule 144A) which permits the selling of any Registrable Securities without registration.

2.9 Legend Removal. After the expiration of the Lock-Up Term, the Company shall cause the legends set forth in Section 4.6 to be removed from the Purchased Shares, no later than two (2) Business Days from receipt of a written request from the Investor pursuant to this Section 2.9, if (a) such shares have been resold under an effective Registration Statement, (b) such shares have been or will be transferred in compliance with Rule 144 under the Securities Act, (c) such shares are eligible for resale pursuant to Rule 144(b)(1)(i) under the Securities Act without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) under the Securities Act as to such shares and without volume or manner-of-sale restrictions or (d) the Investor shall have provided the Company with an opinion of counsel, reasonably satisfactory to the Company, stating that such securities may lawfully be transferred without registration under the Securities Act.

In furtherance of this Section 5.1, the Investor hereby irrevocably appoints the Company and any individuals designated by the Company, and each of them individually, as the attorneys, agents and proxies, with full power of substitution and re-substitution in each of them, for the Investor, and in the name, place and stead of the Investor, to vote (or cause to be voted) or, if applicable, to give consent, in such manner as each such attorney, agent and proxy or his substitute shall in its, his or her sole discretion deem appropriate or desirable with respect to all matters, with respect to all Common Stock and other voting securities of the Company held of record by the Investor or with respect to which the Investor is or may be entitled to vote at any meeting of the Company held after the date hereof, whether annual or special and whether or not an adjourned meeting or, if applicable, to give written consent with respect thereto (the “Irrevocable Proxy”). This Irrevocable Proxy is coupled with an interest, shall be irrevocable and binding on any successor in interest of the Investor and shall not be terminated by operation of Law upon the occurrence of any event. This Irrevocable Proxy shall operate to revoke and render void any proxy as to the Common Stock or any other voting securities of the Company previously granted by the Investor. Notwithstanding the foregoing, the Irrevocable Proxy shall be effective if, at any annual or special meeting of the stockholders of the Company (or any consent in lieu thereof) and at any adjournments or postponements of any such meetings, the Investor (A) fails to appear or otherwise fails to cause any Common Stock or other voting securities of the Company which the Investor holds of record or may be entitled to vote to be counted as present for purposes of calculating a quorum, or (B) fails to vote any Common Stock or other voting securities of the Company in accordance with this Section 5.1, in each case at least ten (10) days prior to the date of such stockholders’ meeting (or within ten (10) days prior to the effective time of an action to be taken by written consent in lieu of such stockholders’ meeting), provided that the Company provides notice of any meeting of stockholders of the Company at least twenty (20) days prior to the date of such stockholder meeting, which notice requirement shall be deemed to be satisfied by the filing of a Form 8-K or definitive proxy statement by the Company disclosing such stockholder meeting. This Irrevocable Proxy shall terminate upon the expiration of the Standstill Term.

In the event that SK Holdings or SK E&S or any of their Affiliates (other than Investor) from time to time own of record any Common Stock or other voting securities of the Company, SK Holdings or SK E&S (as the case may be) shall, and SK Holdings and SK E&S shall cause any such Affiliate to, promptly execute and deliver to the Company an irrevocable proxy, substantially in the form of Exhibit A attached hereto together with any changes requested by the Company as may be required by the Company’s transfer agent or inspector of elections, and irrevocably appoint the Company and any individuals designated by the Company, and each of them individually, with full power of substitution and resubstitution, as its attorney, agent and proxy to vote (or cause to be voted) or to give consent with respect to, all of the Common Stock and other voting securities of the Company which such party is entitled to vote, in such manner as each such attorney, agent and proxy or his substitute shall in its, his or her sole discretion deem appropriate or desirable with respect to the matters set forth in this Section 5.1 (the “Affiliate Proxy”). SK Holdings and SK E&S acknowledge, and shall cause their Affiliates to acknowledge, that each Affiliate Proxy executed and delivered shall be coupled with an interest, shall constitute, among other things, an inducement for the Company to enter into this Agreement, shall be irrevocable and binding on any successor in interest and shall not be terminated by operation of Law upon the occurrence of any event. Such Affiliate Proxy shall operate to revoke and render void any proxy as to the Common Stock or any other voting securities of the Company previously granted by the party granting such proxy. The Investor, SK Holdings and SK E&S acknowledge and agree that it shall be a condition to any Permitted Purchase by any Affiliate of the Investor that such Affiliate execute and deliver to the Company an Affiliate Proxy, and that any purported Permitted Purchase shall be in violation of Section 3 of this Agreement if such Affiliate Proxy is not so executed and delivered upon or prior to such Permitted Purchase. Such Affiliate Proxy shall terminate upon the expiration of the Standstill Term.

6. Board Composition.

(a) Subject to the terms of this Section 6, effective as of the Closing, the Board will appoint a designee of the Investor (the “Investor Designee”), reasonably acceptable to the Board, as a director of the Company for a term expiring at the Company’s 2023 annual meeting of stockholders or such Investor Designee’s earlier death, disability, resignation or removal. The Company and the Investor agree that [______] shall be the initial Investor Designee. The Company agrees that, during the Director Period, the Board shall nominate the individual serving as such Investor Designee (or any individual subsequently designated by the Investor to serve as the Investor Designee) for election or re-election, as the case may be, as a director at each subsequent meeting of the Company’s stockholders at which directors are to be elected, and use commercially reasonable efforts to cause the Investor Designee to be elected or re-elected, including providing the same level of support as is provided for other nominees. Upon the end of the Director Period, the Investor shall cause the Investor Designee to tender to the Board, as soon as practicable and in any event within five (5) days following the end of the Director Period, his or her resignation from the Board. During the Director Period, the Company will not decrease the size of the Board if such decrease would require the resignation of the Investor Designee.

(b) As a condition to any appointment or nomination for election to the Board, each Investor Designee shall (i) meet the qualifications required of all directors of the Company by the Company’s Corporate Governance and Nominating Committee and those mandated by applicable Law, (ii) agree, in writing, to be bound by the terms and conditions of all of the Company’s policies applicable to its directors, (iii) make such acknowledgements and enter into such agreements as the Company requires of all directors, including, without limitation, with respect to confidentiality, the Company’s code of ethics, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ policy and Section 16 reporting procedures, and (iv) be able to dedicate sufficient time and resources for the diligent performance of the duties required of a member of the Board (the “Director Conditions”). Without limiting the foregoing, each proposed Investor Designee shall be subject to satisfaction of the criteria for Board membership established by the Company’s Corporate Governance Guidelines, including the director qualification criteria thereof, as determined in the reasonable and good faith discretion of the Corporate Governance and Nominating Committee of the Board and the Board in the same manner as the Corporate Governance and Nominating Committee of the Board and the Board would consider any candidate for Board membership. The Board or the Corporate Governance and Nominating Committee of the Board will evaluate the Investor Designee for potential roles on the committees of the Board, consistent with evaluations of other directors for such positions and subject to applicable Law and the listing rules and requirements of The Nasdaq Stock Market.

(c) If an Investor Designee resigns from the Board (whether pursuant to the Company’s Majority Voting Policy or otherwise), is removed, or refuses or is unable to serve or fulfill his or her duties as a director because of death or disability, in each case prior to the expiration of the Director Period, the Investor shall have the right to select a replacement Investor Designee, reasonably acceptable to the Board and subject to compliance with the Director Conditions, and shall provide the Company with the name of and relevant background information for such replacement Investor Designee. Subject to the terms of this Section 6, within fifteen (15) days following receipt of such information and compliance with the Director Conditions, the Board will appoint such replacement Investor Designee to the Board to replace the departing Investor Designee to serve the remaining term of the departing Investor Designee, and the replacement Investor Designee shall be considered an Investor Designee for all purposes of this Section 6.

(d) All confidential or proprietary information and data relating to the Company and its Affiliates provided by the Company to the Investor Director shall be deemed confidential information and will be kept confidential and not disclosed to any Person outside of the Company. Notwithstanding the confidentiality obligations set forth in Section 6(b)(iii) and the foregoing, and subject to Section 7.16, the Investor Designee shall be permitted to disclose such confidential information to the executive officers and members of the Board of Directors of the Investor, Plutus, SK E&S Americas, SK Holdings and SK E&S, and their respective advisers (such as legal counsel) having a duty of confidentiality to the Investor, Plutus, SK E&S Americas, SK Holdings and SK E&S, as the case may be, provided (i) such disclosure is made on a need-to-know basis solely for the purposes of, and to the extent necessary to, monitor and make decisions regarding the Investor’s investment in the Company, and (ii) that the Investor will be liable for any breach by any of such Persons of the confidentiality obligations applicable to the Investor Designee. Upon the resignation or removal of the Investor Designee from the Board and written request (including via email) from the Company, such Investor Designee shall either promptly (x) destroy all confidential information of the Company that he or she received in his or her capacity as a director in his or her possession or control and any copies thereof or (y) return to the Company all confidential information of the Company that he or she received in his or her capacity as a director in his or her possession or control and any copies thereof (but the Investor Designee need not purge electronic archives and backups), and, in either case, confirm in writing (which may be via email) to the Company that all such material has been destroyed or returned, as applicable, in compliance with this Section 6.

(e) If any Investor Designee is an employee of, or otherwise compensated by, the Investor, SK Holdings, SK E&S or any of their respective Affiliates, such Investor Designee shall not be entitled to any compensation from the Company in connection with his or her role as a director or service on the Board or any committee. The Investor Designee will be entitled to reimbursement from the Company of out of pocket expenses in connection with his or her role as a director consistent with other directors on the Board.

(f) Notwithstanding anything contained herein to the contrary, if the Board (or any committee thereof) shall consider (i) a proposed contract, transaction or other arrangement between the Investor, SK Holdings, SK E&S (or any of their respective Affiliates (disregarding for such purposes the penultimate sentence of the definition of “Affiliate” in Section 1(b) of this Agreement)), on the one hand, and the Company or any of its Affiliates, on the other hand, (ii) the enforcement or waiver of the rights of the Company or any of its Affiliates under any agreement between the Investor, SK Holdings, SK E&S (or any of their respective Affiliates (disregarding for such purposes the penultimate sentence of the definition of “Affiliate” in Section 1(b) of this Agreement)), on the one hand, and the Company or any of its Affiliates, on the other hand, or (iii) a matter which the Board determines in good faith presents an actual or potential conflict of interest for the Investor Designee, then the Investor Designee will, if directed by the Board Chair or the remaining directors, be excluded from participation in such Board or committee meeting (or portion thereof, as applicable) at which such matters are to be discussed, and the Investor Designee will not be entitled to receive copies of the materials or other documents relating to such matter or meeting (or portion thereof, as applicable).
