(h)The Company has filed each form, report, statement, schedule, prospectus, proxy and registration statement (the “SEC Documents”) that the Company was required to file with the Commission since its initial registration of the Common Stock with the Commission and through the date hereof. As of their respective filing dates (the “Filing Dates”), the SEC Documents complied in all material respects with the requirements of the Securities Act, the Exchange Act, and the rules and regulations of the Commission promulgated thereunder and currently in effect at such Filing Date, and none of the SEC Documents, when filed, or if amended prior to the date of this Agreement, as of the date of such amendment with respect to those disclosures that were amended, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As of the date hereof, there are, and upon Closing there shall be, no outstanding or unresolved comments in comment letters from the staff of the Division of Corporation Finance of the Commission with respect to any of the SEC Documents.

(i)The Company is not, and immediately after receipt of payment for the Shares and consummation of the Rights Offering, will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(j)As of November 6, 2023, the authorized capital stock of the Company consists of 100,500,000 shares of Common Stock, par value $0.0001 per share, of which 31,853,378 are issued and outstanding.

There are no stockholder agreements, voting trusts or other agreements or understandings to which the Company is a party or by which it is bound relating to the voting of any securities of the Company, other than as set forth in the SEC Documents and the Amended and Restated Standstill Agreement.

(a)Filing of Resale Registration Statement. The Company shall file with the Commission (at the Company’s sole cost and expense) a registration statement registering the resale of the Backstop Acquired Shares (the “Resale Registration Statement”) as soon as

reasonably practicable after the Closing Date, and the Company shall use its commercially reasonable efforts to have the Resale Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) May 31, 2024 and (ii) the tenth (10th) Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Resale Registration Statement will not be “reviewed” or will not be subject to further review ((i) and (ii) collectively, the “Effectiveness Deadline”); provided, that if such day falls on a Saturday, Sunday, or other day that the Commission is closed for business, the Effectiveness Deadline shall be extended to the next Business Day on which the Commission is open for business. The Company will use its commercially reasonable efforts to provide a draft of the Resale Registration Statement to the undersigned for review and comment at least two (2) Business Days in advance of filing the Resale Registration Statement; provided that, for the avoidance of doubt, in no event shall the Company be required to delay or postpone the filing of the Resale Registration Statement as a result of or in connection with Backstop Investor’s review. The Company agrees that, except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of the Resale Registration Statement as set forth in this Section 6, the Company will use its commercially reasonable efforts to cause the Resale Registration Statement to remain effective with respect to Backstop Investor until the earlier of (i) two years from the issuance of the Backstop Acquired Shares, (ii) the date on which all of the Backstop Acquired Shares shall have been sold, or (iii) on the first date on which the undersigned can sell all of its Backstop Acquired Shares (or shares received in exchange therefor) under Rule 144 without limitation as to the manner of sale or the amount of such securities that may be sold and without the requirement for the Company to be in compliance with the current public information required under Rule 144. The Company will use reasonable efforts to make and keep public information available (as those terms are understood and defined in Rule 144) and file all reports, and provide all customary and reasonable cooperation, necessary to resell Registrable Securities pursuant to the Resale Registration Statement or Rule 144, as applicable, and maintain the qualification of the Registrable Securities for listing on Nasdaq. For purposes of this Section 6, “Registrable Securities” shall mean the Backstop Acquired Shares and any other equity security of the Company or any of its subsidiaries issued or issuable with respect to the Backstop Acquired Shares by way of a stock dividend or stock split or in connection with a recapitalization, merger, consolidation, spin-off, reorganization or similar transaction; provided, however, that, as to any particular Registrable Security, such securities shall cease to be Registrable Securities upon the earliest to occur of: (A) a registration statement as contemplated under this Section 6 with respect to the sale of such securities shall have become effective under the Securities Act and such securities shall have been sold, transferred, disposed of or exchanged in accordance with such registration statement by the Backstop Investor; (B) such securities shall have been otherwise transferred, new certificates for such securities not bearing a legend restricting further transfer shall have been delivered by the Company and subsequent public distribution of such securities shall not require registration under the Securities Act; (C) such securities shall have ceased to be outstanding; (D) such securities may be sold without registration pursuant to Rule 144 or any successor rule promulgated under the Securities Act (but with no volume or other restrictions or limitations including as to manner or timing of sale); and (E) such securities have been sold to, or through, a broker, dealer or underwriter in a public distribution or other public securities transaction. For purposes of this Section 6, “Holder” shall mean Backstop Investor or any affiliate of Backstop Investor to which the rights under this Section 6 shall have been assigned. The Company’s obligations to include the Backstop Acquired Shares in the Resale Registration Statement are contingent upon Backstop Investor furnishing in writing to the Company such information regarding Backstop Investor, the securities of the Company held by Backstop Investor and the intended method of disposition of the Backstop Acquired Shares as shall be reasonably requested by the Company to effect the registration of the Backstop Acquired Shares, and Backstop Investor shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations, including providing that the Company shall be entitled to postpone and suspend the effectiveness or use of

the Resale Registration Statement during any customary blackout or similar period or as permitted hereunder. In the case of the registration effected by the Company pursuant to this Agreement, the Company shall, upon reasonable request, inform Backstop Investor as to the status of such registration. Notwithstanding anything to the contrary contained herein, the Company may delay or postpone filing of such Resale Registration Statement, and from time to time require Backstop Investor not to sell under such Resale Registration Statement or suspend the use or effectiveness of any such Resale Registration Statement if it determines that in order for the Resale Registration Statement to not contain a material misstatement or omission, an amendment thereto would be needed, or if, in the reasonable determination of the Company’s board of directors, upon advice of legal counsel, such filing or use could materially affect a bona fide business or financing transaction of the Company or would require premature disclosure of information that could materially adversely affect the Company (each such circumstance, a “Suspension Event”); provided, that, (w) the Company shall not so delay filing or so suspend the use of the Resale Registration Statement for a period of more than sixty (60) consecutive days or more than two (2) times in any three hundred sixty (360) day period and (x) the Company shall use commercially reasonable efforts to make such Resale Registration Statement available for the sale by the undersigned of such securities as soon as practicable thereafter.

(b)Additional Procedures. In the case of any registration of the Backstop Acquired Shares effected by the Company pursuant to Section 6(a) (a “Resale Registration”), the Company shall, upon reasonable request, inform Backstop Investor as to the status of such Resale Registration. At its expense, the Company shall:

(i)advise Backstop Investor, as expeditiously as possible:

(1)when a Resale Registration Statement or any amendment thereto has been filed with the Commission;

(2)after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of any Resale Registration Statement or the initiation of any proceedings for such purpose;

(3)of the receipt by the Company of any notification with respect to the suspension of the qualification of the Backstop Acquired Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(4)subject to the provisions in this Agreement, of the occurrence of any event that requires the making of any changes in any Resale Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading;

(ii)use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Resale Registration Statement as soon as reasonably practicable;

(iii)upon the occurrence of any event contemplated in Section 6(b)(i)(4) above, except for such times as the Company is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Resale Registration Statement, the Company shall use its commercially reasonable

efforts to as soon as reasonably practicable prepare a post-effective amendment to such Resale Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Backstop Acquired Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(iv)use its commercially reasonable efforts to allow Backstop Investor to review disclosure regarding Backstop Investor in the Resale Registration Statement; and

(v)otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by Backstop Investor, consistent with the terms of this Agreement, in connection with the registration of the Backstop Acquired Shares.

(c)Suspension Event. Upon receipt of any written notice from the Company of the occurrence of any Suspension Event during the period that the Resale Registration Statement is effective or if as a result of a Suspension Event, the Resale Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, the undersigned agrees that (i) it will immediately discontinue offers and sales of the Backstop Acquired Shares under the Resale Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the undersigned receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law, subpoena or regulatory request or requirement. If so directed by the Company, the undersigned will deliver to the Company, or in the undersigned’s sole discretion destroy, all copies of the prospectus covering the Backstop Acquired Shares in the undersigned’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Backstop Acquired Shares shall not apply (w) to the extent the undersigned is required to retain a copy of such prospectus (A) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (B) in accordance with a bona fide pre-existing document retention policy or (x) to copies stored electronically on archival servers as a result of automatic data back-up.

(d)Demands & Requests for Underwritten Shelf Takedowns. At any time that the Company has not effected or is not diligently pursuing a Resale Registration pursuant to Section 6(a), after the date that is one hundred and twenty (120) days after the Closing Date, Backstop Investor may request registration under the Securities Act of all or any portion of their Registrable Securities on (i) Form S-3 or any similar short-form registration statement (a “Short-Form Registration”) or (ii) to the extent a Short-Form Registration is not available, Form S-1 or any similar long-form registration statement (a “Long-Form Registration”). As soon as practicable following any such request of the Backstop Investor pursuant to this Section 6(d), the Company shall file with the Commission (at the Company’s sole cost and expense) any registration statement needed to effect the Short-Form Registration or Long-Form Registration of the Registrable Securities of the Backstop Investor requested pursuant to the foregoing sentence, and shall use commercially reasonable efforts to have such registration statement declared effective as soon as practicable after the filing thereof. At any time and from time to time after

the Resale Registration Statement or any registration statement filed by the Company pursuant to this Section 6(d) has been declared effective by the Commission, the Backstop Investor (in such capacity, the “Demanding Holder”) may request to sell all or any portion of its Registrable Securities in an underwritten offering that is registered pursuant to the Resale Registration Statement or such other registration statement filed by the Company pursuant to this Section 6(d), as applicable (each, an “Underwritten Shelf Takedown”). All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which notice shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown and the expected price range (net of underwriting discounts and commissions) of such Underwritten Shelf Takedown. In connection with any such request by the Demanding Holder for an Underwritten Shelf Takedown, the Demanding Holder shall have the right to select the underwriters for such offering (which shall consist of one (1) or more reputable nationally or regionally recognized investment banks), such underwriters to be subject to the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed. Notwithstanding anything to the contrary contained in this Agreement, in no event shall the Demanding Holder or any transferee thereof be entitled to request an Underwritten Shelf Takedown (and the Company shall not be obligated to consummate any Underwritten Shelf Takedown with respect to the Demanding Holder or any transferee thereof) during the Lock-Up Period. The Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering (x) shall include securities with a total offering price (including piggyback securities and before deduction of underwriting discounts) reasonably expected to exceed, in the aggregate, $25 million (the “Minimum Takedown Threshold”) or (y) shall be made with respect to all of the Registrable Securities of the Demanding Holder. Except as set forth in the preceding sentences, there shall be no limit to the number of Underwritten Shelf Takedowns that may be requested by the Demanding Holder.

(e)Reduction of Underwritten Shelf Takedowns. If the managing underwriter or underwriters in an Underwritten Shelf Takedown, in good faith, advise the Company and the Demanding Holder in writing that the dollar amount or number of Registrable Securities that the Demanding Holder desires to sell, taken together with all other equity securities that the Company desires to sell and all other equity securities, if any, that have been requested to be sold in such Underwritten Shelf Takedown pursuant to separate written contractual piggyback registration rights held by any other stockholders, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Shelf Takedown without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Shelf Takedown as follows, at all times:

(i)first, the Registrable Securities of the Demanding Holder that the Demanding Holder has requested be included in such Underwritten Shelf Takedown for itself that can be sold without exceeding the Maximum Number of Securities;

(ii)second, to the extent that the Maximum Number of Securities has not been reached under Section 6(e)(i), the equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and

(iii)third, to the extent that the Maximum Number of Securities has not been reached under Section 6(e)(i) and Section 6(e)(ii) and if applicable, the equity securities of any other Holder or any other Persons that the Company is obligated to include in such Underwritten Shelf Takedown pursuant to separate

written contractual arrangements with such Persons and that can be sold without exceeding the Maximum Number of Securities.

(f)Withdrawal. The Demanding Holder shall have the right to withdraw from any Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a “Withdrawal Notice”) to the Company and the underwriter or underwriters (if any) of the Demanding Holder’s intention.

(g)Piggyback Rights. If the Company or the Demanding Holder proposes to conduct a registered offering of, or if the Company proposes to file a registration statement under the Securities Act with respect to an offering of, equity securities of the Company or securities or other obligations exercisable or exchangeable for or convertible into equity securities of the Company, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including an Underwritten Shelf Takedown as set forth above), other than a registration statement (or any registered offering with respect thereto) (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company, (iv) for a dividend reinvestment plan or (v) the Rights Offering, then the Company shall give written notice of such proposed offering to all Holders as soon as practicable but not less than four calendar days before the anticipated filing date of such registration statement or, in the case of any Underwritten Shelf Takedown, the applicable “red herring” prospectus or prospectus supplement used for marketing such offering, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing underwriter or underwriters, if any and if known, in such offering, and (B) offer to all of the Holders the opportunity to include in such registered offering such number of Registrable Securities as such Holders may request in writing within three calendar days after receipt of such written notice (such registered offering, a “Piggyback Registration”). Subject to Section 6(h), the Company shall cause all Registrable Securities requested by the Holders to be included in such Piggyback Registration and shall use its reasonable best efforts to cause the managing underwriter or underwriters, if applicable, to permit the Registrable Securities requested by the Holders pursuant to this Section 6(g) to be included in a Piggyback Registration on the same terms and conditions as any similar securities of the Company included in such registered offering and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof.

(h)Reduction of Piggyback Registration. If the managing underwriter or underwriters in an underwritten offering that is to be a Piggyback Registration (other than an Underwritten Shelf Takedown initiated by the Demanding Holder as reductions of such Underwritten Shelf Takedowns are governed by Section 6(e)), in good faith, advises the Company and the Holders participating in the Piggyback Registration in writing that the dollar amount or number of equity securities that the Company desires to sell, taken together with (x) the equity securities, if any, as to which registration or a registered offering has been demanded pursuant to separate written contractual arrangements with Persons other than the Holders under this Agreement and (y) the equity securities, if any, as to which registration has been requested pursuant to Section 6(g), exceeds the Maximum Number of Securities, then: (i) if the registration is initiated and undertaken for the Company’s account, the Company shall include in any such registration: (A) first, the equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Section 6(g), pro rata, based on the respective number of Registrable Securities that each Holder has requested be included in such underwritten offering and the aggregate number of Registrable Securities that the Holders have requested to be included in such underwritten

offering, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the equity securities, if any, as to which registration or a registered offering has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities and (ii) if the registration or registered offering is pursuant to a request by the Demanding Holder of Registrable Securities pursuant to Section 6 hereof, then the Company shall include in any such registration or registered offering securities pursuant to Section 6(e).

(i)Piggyback Registration Withdrawal. Any Holder of Registrable Securities (other than the Demanding Holder having initiated an Underwritten Shelf Takedown, whose right to withdrawal from such Underwritten Shelf Takedown, and related obligations, shall be governed by Section 6(f)) shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the underwriter or underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the registration statement filed with the Commission with respect to such Piggyback Registration or, if applicable, the filing of the applicable “red herring” prospectus or prospectus supplement with respect to such Piggyback Registration used for marketing such transaction. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the registration expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 6(i).

(a)The Backstop Investor agrees that it shall not (i) sell, exchange, transfer or assign, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly or (ii) enter into any swap or other arrangement that transfers to another Person, in whole or in part, any of the economic consequences of ownership (each, a “Transfer”) of the Backstop Acquired Shares for the period beginning on the Closing Date and ending on the six (6) month anniversary of the Closing Date (the “Lock-Up Period”). For the avoidance of doubt, the Backstop Investor shall retain all of its rights as a stockholder of the Company with respect to the Backstop Acquired Shares during the Lock-Up Period, including the right to vote any Backstop Acquired Shares that the Backstop Investor is entitled to vote.

(b)In order to enforce this Section 7, the Company may impose stop-transfer instructions with respect to Backstop Acquired Shares until the end of the Lock-Up Period.

(a)This Agreement shall terminate upon the earliest to occur of (i) such date and time as the Rights Offering is validly terminated in accordance with its terms without being consummated, (ii) upon the mutual written agreement of both parties hereto to terminate this Agreement, or (iii) by written notice from the Backstop Investor given any time on or after February 15, 2024, if the Closing has not occurred by such date and the Backstop Investor’s breach was not the primary reason the Closing failed to occur by such date. The Company shall notify Backstop Investor of the termination of the Rights Offering without it being consummated promptly after the termination thereof.

(b)If this Agreement is terminated pursuant to Section 8(a), this Agreement, shall forthwith become wholly void and of no further effect (other than Section 9, which shall remain in full force and effect); provided, that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination or common law intentional fraud in the making of any representation or warranty hereunder, and each party will be entitled to any

remedies at law or in equity to recover losses, liabilities or damages arising from such breach or fraud.

(a)The Company agrees to indemnify and hold harmless the Backstop Investor, its affiliates (within the meaning of Rule 405 under the Securities Act), and each of their respective shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), and each person who controls (within the meaning of the Securities Act or the Exchange Act) the Backstop Investor or its affiliates (within the meaning of Rule 405 under the Securities Act) (all such Persons being hereinafter referred to, collectively, as the “Backstop Investor Parties”), from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, any reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) that any such Backstop Investor Party may suffer or incur as a result of any untrue statement or alleged untrue statement of any material fact contained in the Offering Documents or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading (except to the extent such untrue statement, alleged untrue statement, omission or alleged omission, as applicable, was made in reliance upon or in conformity with information relating to the Backstop Investor or its affiliates furnished in writing to the Company by or on behalf of the Backstop Investor expressly for use in the Offering Documents).

(b)The Backstop Investor agrees to indemnify and hold harmless the Company and its directors, officers, employees and agents (all such Persons being hereinafter referred to, collectively, as the “Company Parties”), from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, any reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) that any such Company Party may suffer or incur resulting from any untrue statement of material fact contained in the Offering Documents, but only to the extent that such untrue statement was made in reliance or in conformity with information relating to the Backstop Investor or its affiliates furnished in writing to the Company by or on behalf of the Backstop Investor expressly for use in the Offering Documents. Notwithstanding anything to the contrary set forth herein, in no event shall the total indemnification obligation of the Backstop Investor pursuant to this Agreement be greater in amount than the aggregate dollar amount of net proceeds received by the Company from the issuance by the Company of shares of Common Stock to Persons other than the Backstop Investor pursuant to such Persons’ exercise of their respective Rights in the Rights Offering.

(c)Any person entitled to indemnification herein shall (1) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (2) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent. An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment

of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d)The terms of this Section 9 shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, employee, agent, affiliate or controlling person of such indemnified party and shall the termination of this Agreement for any reason, the Closing and the transfer of the Shares purchased pursuant to this Agreement.

(e)If the indemnification provided under this Section 9 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by or on behalf of, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 9 from any person who was not guilty of such fraudulent misrepresentation. Any contribution by the Backstop Investor pursuant to this Section 9(e) shall be limited in amount to aggregate dollar amount of net proceeds received by the Company from the issuance by the Company of shares of Common Stock to Persons other than the Backstop Investor pursuant to such Persons’ exercise of their respective Rights in the Rights Offering. Notwithstanding anything to the contrary herein, in no event will any party be liable for consequential, special, exemplary or punitive damages in connection with this Agreement.

(a)Notices. All notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand, claim, or other communication hereunder shall be deemed duly given (i) when delivered personally to the recipient, (ii) when sent by electronic mail, on the date and time of transmission to such recipient, provided that no electronic mail is undeliverable or other rejection notice is generated, (iii) one (1) Business Day after being sent to the recipient by reputable overnight courier service (charges prepaid), or (iv) four (4) Business Days after being mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, and, in each case, addressed to the intended recipient at its address or electronic mail address, as applicable, specified on the signature page hereof or to such electronic mail address or address as subsequently modified by written notice given in accordance with this Section 10(a).

Each of the Parties hereto hereby irrevocably waives, and agrees not to assert in any action or proceeding with respect to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason, (b) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) to the fullest extent permitted by applicable legal requirements, any claim that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. Without limiting the foregoing, each Party agrees that service of process as provided in Section 9 shall be deemed effective services of process on such Party.

11.    Counterparts.

This Agreement may be executed in two or more counterparts, each of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the Parties and delivered to the other Party (including by means of electronic delivery or facsimile).

12.    No Litigation.

Prior to the Termination Date, each Party hereby covenants and agrees that it shall not, and shall not permit any of its representatives acting on its behalf to, directly or indirectly, alone or in concert with others, encourage, pursue, threaten or initiate any lawsuit, claim or proceeding before any court (each, a “Legal Proceeding”) against the other Party, except for (a) any Legal Proceeding initiated primarily to remedy a breach of or to enforce this Agreement; (b) counterclaims with respect to any Legal Proceeding initiated by, or on behalf of one Party or its Affiliates against the other Party or its Affiliates; (c) any Legal Proceeding initiated primarily to exercise a Party’s statutory appraisal rights; or (d) any Legal Proceeding initiated primarily by the Pale Fire Parties to receive damages or settlement proceeds in their capacities as stockholders of the Company in connection with a class action proceeding brought by a named plaintiff other than the Pale Fire Parties; provided, however, that the foregoing shall not prevent any Party or any of its representatives from responding to oral questions, interrogatories, requests for information or documents, subpoenas, civil investigative demands or similar processes (each, a “Legal Requirement”) in connection with any Legal Proceeding if such Legal Proceeding has not been initiated by, on behalf of or at the direct or indirect suggestion of such Party or any of its representatives acting on its behalf; provided, further, that in the event any Party or any of its representatives receives such a Legal Requirement, such Party shall give prompt written notice of such Legal Requirement to the other Party (except where such notice would be legally prohibited or not practicable). Each Party represents and warrants that, as of the date of this Agreement, it has not filed any lawsuit against the other Party.

13.    Securities Laws.

The Pale Fire Parties acknowledge that they understand their obligations under the U.S. securities laws. Subject to compliance with such laws and any restrictions set forth in the Backstop Agreement with respect to the Remaining Shares, the Pale Fire Parties shall in any event be free to trade or engage in such transactions during periods when the members of the Board are permitted to do so, and the Company shall notify the Pale Fire Parties reasonably in advance when such “open window” trading periods begin and end. The Company acknowledges that none of the provisions herein shall in any way limit the activities of the Pale Fire Parties in

their respective ordinary course of businesses if such activities do not violate applicable securities laws or the obligations specifically agreed to under this Agreement and the Backstop Agreement. For the avoidance of doubt, it is understood and agreed that any restrictions contained in any policies, procedures, processes, codes, rules, standards and guidelines applicable to other directors of the Company (collectively, the “Company Policies”) that are applicable to Senkypl and Barta (in their capacities as officers and/or directors of the Company), including any restrictions on pledging or making purchases on margin of securities of the Company, entering into derivative or hedging arrangements designed to offset a decrease in the value of the Company’s securities or otherwise trading the Company’s securities during open window trading periods shall be deemed to apply to the Pale Fire Parties (and any of their controlled Affiliates). Other than pursuant to an approved Rule 10b5-1 trading plan, it is understood and agreed that, consistent with the Company Policies, the Pale Fire Parties (and any of their controlled Affiliates) shall not be free to trade in the Company’s securities (including, without limitation entering into cash-settled total return swap agreements referencing shares of Common Stock) during “open window” trading periods without the prior approval of the Company (which approval shall not be unreasonably withheld), and shall be prohibited from trading during blackout periods established by the Company and generally applicable to all of the Company’s directors. In addition, nothing contained in this Agreement shall restrict the ability of the Pale Fire Parties from purchasing, selling or otherwise trading securities of the Company pursuant to any Rule 10b5-1 trading plan adopted in accordance with applicable law and the Company Policies. For the avoidance of doubt, nothing contained in this Agreement shall restrict the ability of the Pale Fire Parties from performing their obligations under the Backstop Agreement.
