Company nor any such Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not materially and adversely affect the condition, financial or otherwise, or the earnings, business or operations of the Company and its Subsidiaries, taken as a whole.

Promptly after receipt by any Purchaser Party (the “Indemnified Person”) of notice of any demand, claim or circumstances from any third-party which would or might give rise to a claim or the commencement of any Action in respect of which indemnity may be sought pursuant to Section 4.6(a), such Indemnified Person shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all fees and expenses; provided, however, that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company is actually and materially and adversely prejudiced by such failure to notify. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to the retention of such counsel; (ii) the Company shall have failed promptly to assume the defense of such proceeding and to employ counsel reasonably satisfactory to such Indemnified Person in such proceeding; or (iii) in the reasonable judgment of counsel to such Indemnified Person, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Company shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, delayed or conditioned, the Company shall not effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Persons, unless such settlement (A) includes an unconditional release of such Indemnified Person from all liability arising out of such proceeding,

(B) does not require any admission of wrongdoing by such Indemnified Person, and (C) does not obligate or require an Indemnified Person to take, or refrain from taking, any action.

4.7 Listing of Common Stock. In the time and manner required by the Principal Trading Market, the Company shall prepare and file with such Principal Trading Market an additional shares listing application covering all of the Purchased Shares and Underlying Shares and shall use its commercially reasonable efforts to take all steps necessary to cause all of the Purchased Shares and Underlying Shares to be approved for listing on the Principal Trading Market as promptly as possible thereafter.

4.8 Lead Investor Board Observer. During the period commencing on the Closing and ending on the fifth (5th) anniversary of the Closing, and for so long as the Lead Investor (1) holds at least [**]% of the Securities purchased by the Lead Investor as of the Closing Date, and (2) purchases at least [**]% of the maximum amount of New Securities it is permitted to purchase pursuant to Section 4.12 (Pre-Emptive Rights) below, the Lead Investor shall have the right to designate one (1) individual, reasonably acceptable to the Company, to be present and participate in a non-voting capacity at all meetings of the Board of Directors or any committee thereof, including any telephonic meetings but excluding executive sessions of any such meetings (such individual, the “Lead Investor Board Observer”). Any materials that are sent by the Company to the members of the Board of Directors in their capacity as such shall be sent to the Lead Investor Board Observer simultaneously by means reasonably designed to ensure timely receipt by the Lead Investor Board Observer, and the Company will give the Lead Investor Board Observer notice of such meetings, by the same means as such notices are delivered to the members of the Board of Directors and at the same time as notice is provided or delivered to the Board of Directors; provided, that the Lead Investor Board Observer agrees to hold in confidence and trust, to act in a fiduciary manner with respect to and not to disclose any information provided to or learned by the Lead Investor Board Observer acting in such capacity, whether in connection with the Lead Investor Board Observer’s attendance at meetings of the Board of Directors or any committee thereof, in connection with the receipt of materials delivered to the Board of Directors or any committee thereof or otherwise. Notwithstanding the provisions of this Section 4.8, the Company reserves the right to exclude the Lead Investor Board Observer from any meeting of the Board of Directors, or a portion thereof, and to redact portions of any materials delivered to the Lead Investor Board Observer, where and to the extent that the Company reasonably believes that withholding such information or excluding the Lead Investor Board Observer from attending such meeting of the Board of Directors, or a portion thereof, is reasonably necessary: (i) to preserve attorney-client, work product or similar privilege between the Company and its counsel with respect to any matter; (ii) to protect trade secrets or to comply with the terms and conditions of confidentiality agreements between the Company and any third parties; or (iii) because the Board of Directors has determined in good faith that there exists, with respect to the subject of such deliberation or such information, an actual or potential conflict of interest between the Lead Investor and the Company. The Lead Investor Board Observer shall use the same degree of care to protect the Company’s confidential and proprietary information as the Lead Investor uses to protect its confidential and proprietary information of like nature, but in no circumstances with less than reasonable care.

4.9 No Rights Agreement. The Company shall not enter into any poison pill agreement, stockholders’ rights plan or similar agreement that shall limit the rights of a Purchaser to acquire Common Stock unless such poison pill agreement, stockholders’ rights plan or similar agreement grants an exemption or waiver to the Purchaser immediately effective upon execution of such plan or agreement that would allow the Purchaser to acquire such Common Stock.

4.10 Certain Transactions. Prior to the Closing, the Company will not merge or consolidate into, or sell, transfer or lease all or substantially all of its property or assets to, any other party.

4.11 Ordinary Course of Business. Prior to the earlier of the Closing Date and the termination of this Agreement pursuant to Section 6.16, the Company shall, and shall cause each Subsidiary to, use reasonable best efforts to carry on its business in the ordinary course of business and to maintain and preserve its and such Subsidiary’s business (including its organization, assets, properties, goodwill and insurance coverage) and preserve business relationships with customers, strategic partners, suppliers, distributors and others having business dealings with it. Without limiting the generality of the foregoing, to the extent reasonably practicable, the Company shall

consult with Purchasers prior to taking any material actions outside of the ordinary course of business at any time prior to the earlier of the Closing Date and termination of this Agreement pursuant to Section 6.16.

4.12 Pre-Emptive Rights.

(a) Sale of New Securities. If, at any time following the Closing and ending on the fifth (5th) anniversary of the Closing, and for so long as the Lead Investor (1) holds at least [**]% of the Securities purchased by the Lead Investor as of the Closing Date and (2) purchases at least [**]% of the maximum amount of New Securities it is permitted to purchase pursuant to this Section 4.12, the Company or any of its Subsidiaries makes any nonpublic offering (for clarity, meaning any offering that is not registered under the Securities Act or in a marketed “Rule 144A” offering of debt securities to accredited investors) of any Common Stock, other capital stock of the Company or other type of equity interest, warrants, options or other securities of the Company, including any securities that are convertible into or exchangeable into the foregoing (other than (i) Common Stock issuable to officers, employees, directors, managers or independent contractors of the Company or any of its Subsidiaries in connection with warrants, options, notes or other rights to acquire securities of the Company including any such shares issued pursuant to a Stock Plan, (ii) Common Stock, other capital stock of the Company or any other type of equity interest, warrants, options, convertible securities or other securities offered, sold or issued by the Company upon conversion, exercise or exchange of any securities of the Company outstanding immediately prior to the Closing, (iii) Common Stock, other capital stock of the Company or any other type of equity interest, warrants, options, convertible securities or other securities offered, sold or issued by the Company to equipment lessors, pursuant to an equipment leasing transaction, (iv) Common Stock, other capital stock of the Company or any other type of equity interest, warrants, options, convertible securities or other securities offered, sold or issued by the Company to a third-party financial institution in connection with a bona fide borrowing by the Company or its Subsidiaries, (v) Common Stock, other capital stock of the Company or any other type of equity interest, warrants, options, convertible securities or other securities offered or issued in connection with any stock split, stock combination, stock dividend, distribution or recapitalization, (vi) Common Stock, other capital stock of the Company or any other type of equity interest, warrants, options, convertible securities or other securities offered, sold or issued by the Company in connection with a strategic partnership or commercial arrangement, (vii) Common Stock, other capital stock of the Company or any other type of equity interest, warrants, options, convertible securities or other securities offered, sold or issued by the Company as acquisition consideration pursuant to the acquisition of another corporation, entity or business by the Company by merger, purchase of substantially all of the assets or other reorganization or to a joint venture agreement, and (viii) Underlying Shares offered sold or issued by the Company upon conversion, exercise or exchange of any of the Securities) (any such security, a “New Security”), then the Lead Investor shall have the right (but not the obligation) to acquire from the Company for the same price and on the same terms as such New Securities are proposed to be offered to others, up to the amount of New Securities in the aggregate required to enable it to maintain its proportionate Common Stock interest in the Company (calculated on a fully diluted basis, assuming the exercise in full, for cash, of any convertible or exchangeable securities, including the Securities, and for clarity, without regard to any limitation on exercise contained in the Pre-Funded Warrants) immediately prior to any such issuance of New Securities; provided, however, that notwithstanding anything in this Section 4.12 to the contrary, if such New Security is Common Stock or securities that are convertible into or exchangeable into Common Stock, then if the Lead Investor then holds any Pre-Funded Warrants, such New Securities purchased by the Lead Investor pursuant to this Section 4.12 shall instead be issued to the Lead Investor as additional Pre-Funded Warrants. The amount of New Securities that the Lead Investor shall be entitled to purchase in the aggregate shall be determined by multiplying (x) the total number or principal amount of such offered New Securities by (y) a fraction, the numerator of which is the sum of (i) the number of shares of Common Stock held by the Lead Investor, if any, and (ii) without duplication, the number of shares of Common Stock represented by the Pre-Funded Warrants held by the Lead Investor (for clarity, without regard to any limitation on exercise contained in the Pre-Funded Warrants), and the denominator of which is the total number of shares of Common Stock then outstanding (calculated on a fully diluted basis as of such date, assuming the exercise in full, for cash, of any convertible or exchangeable securities, including the Securities, and for clarity, without regard to any limitation on exercise contained in the Pre-Funded Warrants) (the Lead Investor’s “Pro Rata Allocation”); provided that to the extent the issuance of New Securities to the Lead Investor would result in a Stockholder Approval Requirement, the Lead Investor may elect to purchase up to an amount of New Securities that would not cause the Stockholder Approval Requirement.

(b) Notice. In the event the Company proposes to offer or sell New Securities in a nonpublic offering (the “Offering”), it shall give the Lead Investor written notice of its intention, describing the price (or range of prices), anticipated amount of securities, timing, and all other terms upon which the Company proposes to offer the same, no later than ten Business Days, as the case may be, after the Company proposes to pursue the offering. If the information contained in the notice constitutes material non-public information (as defined under the applicable securities laws), the Company shall deliver such notice only to the individuals identified on the Lead Investor’s signature page hereto, and shall not communicate the information to anyone else acting on behalf of the Lead Investor without the consent of one of the designated individuals. The Lead Investor shall have two Business Days from the date of receipt of such a notice to notify the Company in writing that it intends to exercise its rights provided in this Section 4.12 and as to the amount of New Securities the Lead Investor desires to purchase, up to the maximum amount calculated pursuant to Section 4.12(a). Such notice shall constitute a nonbinding indication of interest of the Lead Investor to purchase the amount of New Securities so specified at the price and other terms set forth in the Company’s notice to it. The failure of the Lead Investor to respond within such two Business Day period shall be deemed to be a waiver of the Lead Investor’s rights under this Section 4.12 only with respect to the Offering described in the applicable notice (and not, for the avoidance of doubt, with respect to any future Offerings).

(c) Purchase Mechanism. If the Lead Investor exercises its rights provided in this Section 4.12, the closing of the purchase of the New Securities by the Lead Investor with respect to which such right has been exercised shall take place within three Business Days after the giving of notice of such exercise, which period of time shall be extended for a maximum of 180 days in order to comply with applicable laws and regulations (including receipt of any applicable regulatory or stockholder approvals). Notwithstanding anything to the contrary herein, the closing of the purchase of the New Securities by the Lead Investor will occur no earlier than the closing of the Offering triggering the right being exercised by the Lead Investor. Each of the Company and the Lead Investor agrees to use its commercially reasonable efforts to secure any regulatory or stockholder approvals or other consents, and to comply with any law or regulation necessary in connection with the offer, sale and purchase of, such New Securities.

(d) Failure of Purchase. In the event the Lead Investor fails to exercise its rights provided in this Section 4.12 within said two Business Day period or, if so exercised, the Lead Investor is unable to consummate such purchase within the time period specified in Section 4.12(c) above because of its failure to obtain any required regulatory consent or approval, the Company shall thereafter be entitled (during the period of 60 days following the conclusion of the applicable period) to sell or enter into an agreement (pursuant to which the sale of the New Securities covered thereby shall be consummated, if at all, within 90 days from the date of said agreement) to sell the New Securities not elected to be purchased pursuant to this Section 4.12 by the Lead Investor or which the Lead Investor is unable to purchase because of such failure to obtain any such consent or approval, at a price and upon terms no more favorable in the aggregate to the purchasers of such securities than were specified in the Company’s notice to the Lead Investor. Notwithstanding the foregoing, if such sale is subject to the receipt of any regulatory or stockholder approval or consent or the expiration of any waiting period, the time period during which such sale may be consummated shall be extended until the expiration of three Business Days after all such approvals or consents have been obtained or waiting periods expired, but in no event shall such time period exceed 180 days from the date of the applicable agreement with respect to such sale. In the event the Company has not sold the New Securities or entered into an agreement to sell the New Securities within said 60-day period (or sold and issued New Securities in accordance with the foregoing within 90 days from the date of said agreement (as such period may be extended in the manner described above for a period not to exceed 180 days from the date of said agreement)), the Company shall not thereafter offer, issue or sell such New Securities without again offering such securities to the Lead Investor in the manner provided in this Section 4.12.

(e) Public Offerings. If, at any time following the Closing and ending on the fifth (5th) anniversary of the Closing, and for so long as the Lead Investor (1) holds at least [**]% of the Securities purchased by the Lead Investor as of the Closing Date and (2) purchases at least [**]% of the maximum amount of New Securities it is permitted to purchase pursuant to this Section 4.12, the Company or any of its Subsidiaries makes a public offering of New Securities (for clarity, meaning any offering that is registered under the Securities Act or in a marketed “Rule 144A” offering of debt securities to accredited investors), the Company will instruct the underwriter(s) or placement agent(s) in such offering to contact Lead Investor about such offering no later than one

Business Day prior to the pricing of such offering (provided that in the case of any such public offering Lead Investor will not purchase more than its Pro Rata Allocation of such new securities. If such outreach concerning such proposed public offering would constitute material non-public information (as defined under the applicable securities laws), the Company will instruct the underwriter(s) to contact only the individuals identified on the Lead Investor’s signature page hereto, and shall not communicate the information to anyone else acting on behalf of the Lead Investor without the consent of one of the designated individuals.

(f) Non-Cash Consideration. In the case of the offering of securities for a consideration in whole or in part other than cash, including securities acquired in exchange therefor (other than securities by their terms so exchangeable), the consideration other than cash shall be deemed to be the fair value thereof as determined by the Board of Directors; provided, however, that such fair value as determined by the Board of Directors shall not exceed the aggregate market price of the securities being offered as of the date the Board of Directors authorizes the offering of such securities.

(g) Cooperation. The Company and the Lead Investor shall cooperate in good faith to facilitate the exercise of the Lead Investor’s rights under this Section 4.12, including to secure any required approvals or consents.

(h) Waiver. The Lead Investor may waive any or all of its rights under this Section 4.12 with respect to the purchase or proposed purchase by the Lead Investor of any New Securities (including, without limitation, the Lead Investor’s right to receive written notice from the Company of any proposed Offering at least twenty Business Days prior to the proposed consummation date of any such proposed Offering and the Lead Investor’s right to have a period of at least 30 days after the Lead Investor exercises its rights under this Section 4.12 to purchase the New Securities in respect of which the Lead Investor has exercised such rights) by executing and delivering to the Company a written instrument, document or agreement waiving such rights.

4.13 Ownership Limitation. Notwithstanding anything to the contrary in the Transaction Documents, neither the Company nor any Subsidiary thereof shall take any action (including any redemption, repurchase, or recapitalization of Common Stock, or securities or rights, options or warrants to purchase Common Stock, or securities of any type whatsoever that are, or may become, convertible into or exchangeable into or exercisable for Common Stock), that would cause the Lead Investor’s ownership of voting securities of the Company (together with the ownership by the Lead Investor’s Affiliates of voting securities of the Company) to increase above the then current Maximum Percentage (as defined in the Pre-Funded Warrants), without the prior written consent of the Lead Investor, which consent must be provided on 61 days’ notice (up to a maximum of 19.99%).

4.14 Most Favored Nation. During the period from the date hereof through the Closing, neither the Company nor any of the Subsidiaries shall enter into any additional, or modify any existing, agreements with any existing or future investors in the Company or any of the Subsidiaries that have the effect of establishing rights or otherwise benefitting such investor in a manner more favorable in any respect to such investor than the rights and benefits established in favor of the Lead Investor by this Agreement, unless, in any such case, the Lead Investor has been offered such rights and benefits. The Company represents and warrants to the Lead Investor that as of the date hereof, no agreements exist with other Purchasers that have the effect of establishing rights or otherwise benefitting such Purchasers in a manner more favorable in any respect to such Purchaser than the rights and benefits established in favor of the Lead Investor by this Agreement.

4.15 Reservation of Common Stock. The Company shall reserve and keep available at all times during which the Pre-Funded Warrants are exercisable, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue the Underlying Shares pursuant to this Agreement.

(b) Notwithstanding anything to the contrary, the Purchasers will not exercise its right to require the filing of a Resale Registration Shelf by SpinCo or cause SpinCo to effect an Underwritten Offering or Block Trade (as such terms are defined in the Registration Statement) until such time as SpinCo is eligible to effect a primary offering using a Registration Statement on Form S-3 pursuant to General Instruction I.B.1 of such form.

4.19 Tax Matters.

(a) Without the consent of the Company, no Purchaser will (or, to the Purchaser’s knowledge, will permit any of its Tax-Related Persons to) (i) become a member of a “coordinating group” (within the meaning of Treasury Regulations Section 1.355-7(h)) that includes such Purchaser for purposes of determining whether Section 355(e) of the Code applies as it relates to the Distribution or, (ii) until the date of the Distribution, act pursuant to a “plan or arrangement” (within the meaning of Section 355(d)(7)(B) of the Code) with respect to the acquisition of shares of Company stock or shares of SpinCo stock (including the right to acquire any such shares) with such Purchaser for purposes of determining whether Section 355(d) of the Code applies as it relates to the Distribution, in each case other than together with such Purchaser’s Tax-Related Persons, another Purchaser or such other Purchaser’s Tax-Related Persons.

(b) Without the consent of Company and other than from the Company or SpinCo in an underwritten offering or pursuant to a privately negotiated transaction, no Purchaser will (or will permit any of its Tax-Related Persons that is an Affiliate of the Purchaser to) acquire, or obtain the right to acquire, shares of Company stock or SpinCo stock that (i) with respect to shares of Company stock, together with the Pre-Existing Holding and the Securities, would result in the Purchasers and their Tax-Related Persons (that are Affiliates of the Purchasers or as to whose ownership of Company Stock the Purchasers have knowledge) owning or having the right to acquire, in the aggregate, shares of Company stock in excess of 15% (by vote or value) of all the shares of Company stock outstanding and (ii) with respect to shares of SpinCo stock, together with the shares of SpinCo stock and/or the SpinCo Pre-Funded Warrants received by the Purchasers and their Tax-Related Persons (that are Affiliates of the Purchasers or as to whose ownership of SpinCo stock the Purchasers have knowledge) as a result of the Distribution (and any shares of SpinCo stock received by such Purchaser (or its Tax-Related Persons that are Affiliates of the Purchaser or as to whose ownership of SpinCo stock the Purchasers have knowledge) upon the exercise of a SpinCo Pre-Funded Warrant), would result in the Purchasers and their Tax-Related Persons (that are Affiliates of the Purchasers or as to whose ownership of SpinCo stock the Purchasers have knowledge) owning or having the right to acquire, in the aggregate, shares of SpinCo stock in excess of 15% (by vote or value) of all the shares of SpinCo stock outstanding.

6.9 Survival. Subject to applicable statute of limitations, the representations, warranties, agreements and covenants contained herein shall survive the Closing and the delivery of the Purchased Shares and Pre-Funded Warrants.

6.10 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof.

6.11 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, shall incorporate such substitute provision in this Agreement.

6.12 Replacement of Securities. If any certificate or instrument evidencing any Securities are mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company and the Transfer Agent of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to indemnify and hold harmless the Company and the Transfer Agent for any losses in connection therewith or, if required by the Transfer Agent, a bond in such form and amount as is required by the Transfer Agent. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities. If a replacement certificate or instrument evidencing any Securities is requested due to a mutilation thereof, the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement.

6.13 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to seek specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any Loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at law would be adequate. The Company therefore agrees that the Purchasers shall be entitled to seek temporary and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or other security.

6.14 Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

6.15 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under any Transaction Document. The decision of each Purchaser to purchase Securities pursuant to the Transaction Documents has been made by such Purchaser independently of any other Purchaser and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations,

condition (financial or otherwise) or prospects of the Company or any Subsidiary which may have been made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser and any of its agents or employees shall have any liability to any other Purchaser (or any other Person) relating to or arising from any such information, materials, statement or opinions. Nothing contained herein or in any Transaction Document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

6.16 Termination.

(a) This Agreement may be terminated and the sale and purchase of the Purchased Shares and Pre-Funded Warrants may be abandoned at any time prior to the Closing by either the Company or the Purchasers as follows:

(i) upon the mutual written consent of the Company and the Purchasers;

(ii) by the Company if any of the conditions set forth in Section 5.2 shall have become incapable of fulfillment, and shall not have been waived by the Company;

(iii) by a Purchaser (with respect to itself only) if any of the conditions set forth in Section 5.1 shall have become incapable of fulfillment, and shall not have been waived by the Purchaser; or

(iv) by either the Company or any Purchaser (with respect to itself only) if the Closing has not occurred on or prior to September 30, 2021;

provided, however, that, except in the case of clause (iv) above, the party seeking to terminate its obligation to effect the Closing shall not then be in breach of any of its representations, warranties, covenants or agreements contained in this Agreement if such breach has resulted in the circumstances giving rise to such party’s seeking to terminate its obligation to effect the Closing.

(b) Nothing in this Section 6.16 shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction Documents.

(c) In the event of any termination of this Agreement as provided in this Section 6.16, this Agreement (other than Article VI, which shall remain in full force and effect) shall forthwith become wholly void and of no further force and effect; provided that nothing herein shall relieve any party from liability for intentional breach of this Agreement. Upon a termination in accordance with this Section 6.16, no Purchaser will have any liability to any other Purchaser under the Transaction Documents as a result therefrom.

6.17 Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

6.18 Adjustments in Stock Numbers and Prices; Separation. In the event of any stock split, subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date hereof and prior to Closing, each reference in any Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such event. Notwithstanding the foregoing, in connection with the Separation, no such adjustment shall be made other than as expressly contemplated by this Agreement and Pre-Funded Warrant and SpinCo Pre-Funded Warrant.

6.19 No Recourse. Each party hereto covenants, agrees and acknowledges that no person other than a Purchaser has obligations hereunder and that no person shall have any remedy, recourse or right of recovery against, or contribution from, any of Purchaser Related Party, whether through Purchaser or otherwise, by the enforcement of any assessment or by any legal or equitable proceeding, by virtue of any statute, regulation or applicable law, by or through a claim by or on behalf of Purchaser against any Purchaser Related Party, or otherwise. The term “Purchaser Related Party” means (1) any Affiliate of Purchaser, (2) any former, current or future general or limited partners, members, managers, stockholders, holders of any equity, partnership or limited liability company interest, officers, directors, employees, agents, controlling persons, investment advisors, or assignees of Purchaser or any of its Affiliates, or (3) any former, current or future general or limited partners, members, managers, stockholders, holders of any equity, partnership or limited liability company interest, officers, directors, employees, agents, controlling persons, assignees, investment advisors or Affiliates of any of the foregoing.

Section 2.

Resale Registration Rights

2.1 Resale Registration Rights.

(a) If the Investor could reasonably be deemed to be an “affiliate” of the Company at such time (as such term is defined and used in Rule 144, assuming that all convertible securities (whether equity, debt or otherwise) have been converted into Common Stock), following demand by such Investor the Company shall file with the Commission a Registration Statement on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another appropriate form in accordance with the Securities Act) covering the resale of the Registrable Securities by the Investors (the “Resale Registration Shelf”), and the Company shall file such Resale Registration Shelf as promptly as reasonably practicable following such demand, and in any event within sixty (60) days of such demand. Such Resale Registration Shelf shall include a “final” prospectus, including the information required by Item 507 of Regulation S-K of the Securities Act, as provided by the Investors in accordance with Section 2.7. Notwithstanding the foregoing, before filing the Resale Registration Shelf, the Company shall furnish to the Investors a copy of the Resale Registration Shelf and afford the Investors a reasonable opportunity to review and comment on the Resale Registration Shelf. The Company’s obligation pursuant to this Section 2.1(a) is conditioned upon the Investors providing the information contemplated in Section 2.7 in a timely manner. Notwithstanding the foregoing, if the staff of the Commission (the “Staff”) or the Commission seeks to characterize any offering pursuant to the Resale Registration Shelf as constituting an offering of securities that does not permit such Resale Registration Shelf to become effective and be used for resales by the Investors under Rule 415, or if after the filing of the Resale Registration Shelf with the Commission pursuant to this Section 2.1(a), the Company is otherwise required by the Staff or the Commission to reduce the number of Registrable

Securities included in the Resale Registration Shelf, then the Company shall reduce the number of Registrable Securities to be included in the Resale Registration Shelf until the Staff and the SEC shall so permit the Resale Registration Shelf to become effective and be used as aforesaid. In the event of any reduction in Registrable Securities pursuant to the immediately preceding sentence, the Company shall file, as soon as permitted by the Staff or the Commission, one or more additional Registration Statements on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another appropriate form in accordance with the Securities Act) covering the resale of Registrable Securities by the Investors that have not previously been registered under the Securities Act for resale by the Investors pursuant to Rule 415 until such time as all Registrable Securities have been included in such additional Registration Statement (or in one of such additional Registration Statements) that has or have been declared effective and the prospectus contained therein is available for use by the Investors. The provisions of this Agreement that are applicable to the Resale Registration Shelf shall also be applicable to such additional Registration Statement or each of such additional Registration Statements to the same extent as if such additional Registration Statement were the Resale Registration Shelf. Notwithstanding any provision in this Agreement to the contrary, the Company’s obligations to register Registrable Securities (and any related conditions to the Investor’s obligations) pursuant to this Agreement shall be qualified as necessary to comport with any requirement of the Commission or the Staff as addressed above in this Section 2.1(a).

(b) The Company shall use its reasonable best efforts to cause the Resale Registration Shelf and related prospectuses to become effective as promptly as practicable after filing. The Company shall use its reasonable best efforts to cause such Registration Statement to remain effective under the Securities Act until the earlier of the date (i) all Registrable Securities covered by the Resale Registration Shelf have been sold or may be sold freely without limitations or restrictions as to volume or manner of sale pursuant to Rule 144 or (ii) all Registrable Securities covered by the Resale Registration Shelf otherwise cease to be Registrable Securities pursuant to the definition of Registrable Securities. The Company shall promptly, and in any event within two (2) business days after the Company confirms effectiveness of the Resale Registration Shelf with the Commission, notify the Investors of the effectiveness of the Resale Registration Shelf.

(c) Notwithstanding anything contained herein to the contrary, the Company shall not be obligated to effect, or to take any action to effect, a registration pursuant to Section 2.1(a):

(i) if the Company has and maintains an effective Registration Statement on Form S-3ASR that provides for the resale of an unlimited number of securities by selling stockholders (a “Company Registration Shelf”);

(ii) during the period forty-five (45) days prior to the Company’s good faith estimate of the date of filing of a Company Registration Shelf; or

(iii) if the Company has caused a Registration Statement to become effective pursuant to this Section 2.1 during the prior twelve (12) month period.

(d) If the Company has a Company Registration Shelf in place at any time in which the Investors make a demand pursuant to Section 2.1(a), the Company shall file with the Commission, as promptly as practicable, and in any event within fifteen (15) business days after such demand, a “final” prospectus supplement to its Company Registration Shelf covering the resale of the Registrable Securities by the Investors (the “Prospectus”); provided, however, that the Company shall not be obligated to file more than one Prospectus pursuant to this Section 2.1(d) in any six month period to add additional Registrable Securities to the Company Registration Shelf that were acquired by the Investors other than directly from the Company or in an underwritten public offering by the Company. The Prospectus shall include the information required under Item 507 of Regulation S-K of the Securities Act, which information shall be provided by the Investors in accordance with Section 2.7. Notwithstanding the foregoing, before filing the Prospectus, the Company shall furnish to the Investors a copy of the Prospectus and afford the Investors a reasonable opportunity to review and comment on the Prospectus.

(e) Deferral and Suspension. At any time after being obligated pursuant to this Agreement to file a Resale Registration Shelf or Prospectus, or after any Resale Registration Shelf has become effective or a Prospectus is filed with the Commission, the Company may defer the filing of or suspend the use of any such Resale Registration Shelf or Prospectus, upon giving written notice of such action to the Investors with a certificate signed by the Chief Executive Officer or Chief Financial Officer of the Company stating that in the good faith judgment of the Board, the filing or use of any such Resale Registration Shelf or Prospectus covering the Registrable Securities would be seriously detrimental to the Company or its stockholders at such time and that the Board concludes, as a result, that it is in the best interests of the Company and its stockholders to defer the filing or suspend the use of such Resale Registration Shelf or Prospectus at such time. The Company shall have the right to defer the filing of or suspend the use of such Resale Registration Shelf or Prospectus for a period of not more than one hundred twenty (120) days from the date the Company notifies the Investors of such deferral or suspension; provided that the Company shall not exercise the right contained in this Section 2.1(e) more than once in any twelve month period. In the case of the suspension of use of any effective Resale Registration Shelf or Prospectus, the Investors, immediately upon receipt of notice thereof from the Company, shall discontinue any offers or sales of Registrable Securities pursuant to such Resale Registration Shelf or Prospectus until advised in writing by the Company that the use of such Resale Registration Shelf or Prospectus may be resumed. In the case of a deferred Prospectus or Resale Registration Shelf filing, the Company shall provide prompt written notice to the Investors of (i) the Company’s decision to file or seek effectiveness of the Prospectus or Resale Registration Shelf, as the case may be, following such deferral and (ii) in the case of a Resale Registration Shelf, the effectiveness of such Resale Registration Shelf. In the case of either a suspension of use of, or deferred filing of, any Resale Registration Shelf or Prospectus, the Company shall not, during the pendency of such suspension or deferral, be required to take any action hereunder (including any action pursuant to Section 2.2 hereof) with respect to the registration or sale of any Registrable Securities pursuant to any such Resale Registration Shelf, Company Registration Shelf or Prospectus.

(f) Other Securities. Subject to Section 2.2(e) below, any Resale Registration Shelf or Prospectus may include Other Securities, and may include securities of the Company being sold

for the account of the Company; provided such Other Securities are excluded first from such Registration Statement in order to comply with any applicable laws or request from any Government Entity, Nasdaq or any applicable listing agency. For the avoidance of doubt, no Other Securities may be included in an Underwritten Offering pursuant to Section 2.2 without the consent of the Investors.

2.2 Sales and Underwritten Offerings of the Registrable Securities.

(a) Notwithstanding any provision contained herein to the contrary, and provided that an Investor could reasonably be deemed to be an “affiliate” of the Company at such time (as such term is defined and used in Rule 144, assuming that all convertible securities (whether equity, debt or otherwise) have been converted into Common Stock), such Investors, collectively, shall and subject to the limitations set forth in this Section 2.2, be permitted (i) one Underwritten Offering per calendar year, but no more than three Underwritten Offerings in total, and (ii) no more than two Underwritten Offerings or Block Trades in any twelve month period, to effect the sale or distribution of Registrable Securities.

(b) If, pursuant to clause (a) above, the Investors intend to effect an Underwritten Offering or Block Trade pursuant to a Resale Registration Shelf or Company Registration Shelf to sell or otherwise distribute Registrable Securities, they shall so advise the Company and provide as much notice to the Company as reasonably practicable (and, in either case, not less than fifteen (15) business days prior to the Investors’ request that the Company file a prospectus supplement to a Resale Registration Shelf or Company Registration Shelf).

(c) In connection with any offering initiated by the Investors pursuant to this Section 2.2 involving an underwriting of shares of Registrable Securities, the Investors shall be entitled to select the underwriter or underwriters for such offering, subject to the consent of the Company, such consent not to be unreasonably withheld, conditioned or delayed.

(d) In connection with any offering initiated by the Investors pursuant to this Section 2.2 involving an Underwritten Offering of Registrable Securities, the Company shall not be required to include any of the Registrable Securities in such underwriting unless the Investors (i) enter into an underwriting agreement in customary form with the underwriter or underwriters, (ii) accept customary terms in such underwriting agreement with regard to representations and warranties relating to ownership of the Registrable Securities and authority and power to enter into such underwriting agreement and (iii) complete and execute all questionnaires, powers of attorney, custody agreements, indemnities and other documents as may be requested by such underwriter or underwriters. Further, the Company shall not be required to include any of the Registrable Securities in such underwriting if (Y) the underwriting agreement proposed by the underwriter or underwriters contains representations, warranties or conditions that are not reasonable in light of the Company’s then-current business or (Z) the underwriter, underwriters or the Investors require the Company to participate in any marketing, road show or comparable activity that may be required to complete the orderly sale of shares by the underwriter or underwriters.

(e) If the total amount of securities to be sold in any offering initiated by the Investors pursuant to this Section 2.2 involving an underwriting of shares of Registrable Securities exceeds the amount that the underwriters determine in their sole discretion is compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities, including Registrable Securities (subject in each case to the cutback provisions set forth in this Section 2.2(e)), that the underwriters and the Company determine in their sole discretion shall not jeopardize the success of the offering. If the Underwritten Offering has been requested pursuant to Section 2.2(a) hereof, the number of shares that are entitled to be included in the registration and underwriting shall be allocated in the following manner: (a) first, shares of Company equity securities that the Company desires to include in such registration shall be excluded and (b) second, Registrable Securities requested to be included in such registration by the Investors shall be excluded. For the avoidance of doubt, no other person besides the Investors shall be entitled to participate in any Block Trade effected under this Agreement. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round down the number of shares allocated to any of the Investors to the nearest 100 shares.

2.3 Fees and Expenses. All Registration Expenses incurred in connection with registrations pursuant to this Agreement shall be borne by the Company. All Selling Expenses relating to securities registered on behalf of the Investors shall be borne by the Investors.

2.4 Registration Procedures. In the case of each registration of Registrable Securities effected by the Company pursuant to Section 2.1 hereof, the Company shall keep the Investors advised as to the initiation of each such registration and as to the status thereof. The Company shall use its reasonable best efforts, within the limits set forth in this Section 2.4, to:

(a) prepare and file with the Commission such amendments and supplements to such Registration Statement and the prospectuses used in connection with such Registration Statement as may be necessary to keep such Registration Statement effective and current and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement;

(b) furnish to the Investors such numbers of copies of a prospectus, including preliminary prospectuses, in conformity with the requirements of the Securities Act, and such other documents as the Investors may reasonably request in order to facilitate the disposition of Registrable Securities;

(c) use its reasonable best efforts to register and qualify the Registrable Securities covered by such Registration Statement under such other securities or blue sky laws of such jurisdictions in the United States as shall be reasonably requested by the Investors, if required by such laws, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions;

(d) in the event of an Underwritten Offering or Block Trade, and subject to Section 2.2(d), enter into and perform its obligations under an underwriting agreement or Block Trade sale agreement, in usual and customary form (including any “lock-ups” on behalf of the Company

and its directors and officers), with the managing underwriter of such offering and take such other usual and customary action as the Investors may reasonably request in order to facilitate the disposition of such Registrable Securities;

(e) notify the Investors at any time when a prospectus relating to a Registration Statement covering any Registrable Securities is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made. The Company shall use its reasonable best efforts to amend or supplement such prospectus in order to cause such prospectus not to include any 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 light of the circumstances in which they were made;

(f) provide a transfer agent and registrar for all Registrable Securities registered pursuant to such Registration Statement and, if required, a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration;

(g) if requested by an Investor, use reasonable best efforts to cause the Company’s transfer agent to remove any restrictive legend from any Registrable Securities, within two business days following such request;

(h) cause to be furnished, at the request of the Investors, on the date that Registrable Securities are delivered to underwriters for sale in connection with an Underwritten Offering or Block Trade, (i) an opinion, dated such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, and (ii) a letter or letters from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters; and

(i) cause all such Registrable Securities included in a Registration Statement pursuant to this Agreement to be listed on each securities exchange or other securities trading markets on which Common Stock is then listed.

2.5 The Investors Obligations.

(a) Discontinuance of Distribution. The Investors agree that, upon receipt of any notice from the Company of the occurrence of any event of the kind described in Section 2.4(e) hereof, the Investors shall immediately discontinue disposition of Registrable Securities pursuant to any Registration Statement covering such Registrable Securities until the Investors’ receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.4(e) hereof or receipt of notice that no supplement or amendment is required and that the Investors’ disposition of the Registrable Securities may be resumed. The Company may provide appropriate stop orders to enforce the provisions of this Section 2.5(a).

(b) Compliance with Prospectus Delivery Requirements. The Investors covenant and agree that they shall comply with the prospectus delivery requirements of the Securities Act as applicable to them or an exemption therefrom in connection with sales of Registrable Securities pursuant to any Registration Statement filed by the Company pursuant to this Agreement.

(c) Notification of Sale of Registrable Securities. The Investors covenant and agree that they shall notify the Company following the sale of Registrable Securities to a third party as promptly as reasonably practicable, and in any event within thirty (30) days, following the sale of such Registrable Securities.

2.6 Indemnification.

(a) To the extent permitted by law, the Company shall indemnify the Investors, and, as applicable, their officers, directors, and constituent partners, legal counsel for each Investor and each Person controlling the Investors, with respect to which registration, related qualification, or related compliance of Registrable Securities has been effected pursuant to this Agreement, and each underwriter, if any, and each Person who controls any underwriter within the meaning of the Securities Act against all claims, losses, damages, or liabilities (or actions in respect thereof) to the extent such claims, losses, damages, or liabilities arise out of or are based upon (i) any untrue statement (or alleged untrue statement) of a material fact contained in any prospectus or other document (including any related Registration Statement) incident to any such registration, qualification, or compliance, or (ii) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification, or compliance; and the Company shall pay as incurred to the Investors, each such underwriter, and each Person who controls the Investors or underwriter, any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability, or action; provided, however, that the indemnity contained in this Section 2.6(a) shall not apply to amounts paid in settlement of any such claim, loss, damage, liability, or action if settlement is effected without the prior written consent of the Company (which consent shall not unreasonably be withheld, conditioned or delayed); and provided, further, that the Company shall not be liable in any such case to the extent that any such claim, loss, damage, liability, or expense arises out of or is based upon any violation by such Investor of the obligations set forth in Section 2.5 hereof or any untrue statement or omission contained in such prospectus or other document based upon written information furnished to the Company by the Investors, such underwriter, or such controlling Person and stated to be for use therein.

(b) To the extent permitted by law, each Investor (severally and not jointly) shall, if Registrable Securities held by such Investor are included for sale in the registration and related qualification and compliance effected pursuant to this Agreement, indemnify the Company, each of its directors, each officer of the Company who signs the applicable Registration Statement, each

legal counsel and each underwriter of the Company’s securities covered by such a Registration Statement, each Person who controls the Company or such underwriter within the meaning of the Securities Act against all claims, losses, damages, and liabilities (or actions in respect thereof) arising out of or based upon (i) any untrue statement (or alleged untrue statement) of a material fact contained in any such Registration Statement, or related document, or (ii) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made, or (iii) any violation or alleged violation by such Investor of Section 2.5 hereof, the Securities Act, the Exchange Act, any state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law applicable to such Investor and relating to action or inaction required of such Investor in connection with any such registration and related qualification and compliance, and shall pay as incurred to such persons, any legal and any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability, or action, in each case only to the extent that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in (and such violation pertains to) such Registration Statement or related document in reliance upon and in conformity with written information furnished to the Company by such Investor and stated to be specifically for use therein; provided, however, that the indemnity contained in this Section 2.6(b) shall not apply to amounts paid in settlement of any such claim, loss, damage, liability, or action if settlement is effected without the prior written consent of such Investor (which consent shall not unreasonably be withheld, conditioned or delayed); provided, further, that such Investor’s liability under this Section 2.6(b) (when combined with any amounts such Investor is liable for under Section 2.6(d)) shall not exceed such Investor’s net proceeds from the offering of securities made in connection with such registration.

(c) Promptly after receipt by an indemnified party under this Section 2.6 of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 2.6, notify the indemnifying party in writing of the commencement thereof and generally summarize such action. The indemnifying party shall have the right to participate in and to assume the defense of such claim; provided, however, that the indemnifying party shall be entitled to select counsel for the defense of such claim with the approval of any parties entitled to indemnification, which approval shall not be unreasonably withheld, conditioned or delayed; provided further, however, that if either party reasonably determines that there may be a conflict between the position of the Company and the Investors in conducting the defense of such action, suit, or proceeding by reason of recognized claims for indemnity under this Section 2.6, then counsel for such party shall be entitled to conduct the defense to the extent reasonably determined by such counsel to be necessary to protect the interest of such party. The failure to notify an indemnifying party promptly of the commencement of any such action, if prejudicial to the ability of the indemnifying party to defend such action, shall relieve such indemnifying party, to the extent so prejudiced, of any liability to the indemnified party under this Section 2.6, but the omission so to notify the indemnifying party shall not relieve such party of any liability that such party may have to any indemnified party otherwise than under this Section 2.6.

(d) If the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. In no event, however, shall (i) any amount due for contribution hereunder be in excess of the amount that would otherwise be due under Section 2.6(a) or Section 2.6(b), as applicable, based on the limitations of such provisions and (ii) a Person guilty of fraudulent misrepresentation (within the meaning of the Securities Act) be entitled to contribution from a Person who was not guilty of such fraudulent misrepresentation.

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with an Underwritten Offering, or the Block Trade sale agreement in connection with a Block Trade, are in conflict with the foregoing provisions, the provisions in the underwriting agreement or Block Trade sale agreement, as applicable, shall control; provided, however, that the failure of the underwriting agreement or Block Trade agreement to provide for or address a matter provided for or addressed by the foregoing provisions shall not be a conflict between the underwriting agreement or the Block Trade sale agreement and the foregoing provisions.

(f) The obligations of the Company and the Investors under this Section 2.6 shall survive the completion of any offering of Registrable Securities in a Registration Statement under this Agreement or otherwise.

2.7 Information. The Investors shall furnish to the Company such information regarding the Investors and the distribution proposed by the Investors as the Company may reasonably request and as shall be reasonably required in connection with any registration referred to in this Agreement. The Investors agree to, as promptly as practicable (and in any event prior to any sales made pursuant to a prospectus), furnish to the Company all information required to be disclosed in order to make the information previously furnished to the Company by the Investors not misleading in light of the circumstances in which they were made. The Investors agree to keep confidential the receipt of any notice received pursuant to Section 2.4(e) and the contents thereof, except as required pursuant to applicable law. Notwithstanding anything to the contrary herein, the Company shall be under no obligation to name the Investors in any Registration Statement, or to include any Investor’s Registrable Securities in any Registration Statement, if the Investors have not provided the information required by this Section 2.7 with respect to the Investors as a selling securityholder in such Registration Statement or any related prospectus.

2.8 Rule 144 Requirements. With a view to making available to the Investors the benefits of Rule 144 under the Securities Act and any other rule or regulation of the Commission that may at any time permit the Investors to sell Registrable Securities to the public without registration, the Company agrees to use its reasonable best efforts to:

(a) make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act at all times after the date hereof;

(b) 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;

(c) prior to the filing of the Registration Statement or any amendment thereto (whether pre‑effective or post‑effective), and prior to the filing of any prospectus or prospectus supplement related thereto, to provide the Investors with copies of all of the pages thereof (if any) that reference the Investors; and

(d) furnish to any 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 Rule 144, (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 by an Investor in availing itself of any rule or regulation of the Commission which permits an Investor to sell any such securities without registration.

2.9 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not enter into any agreement with any holder or prospective holder of any securities of the Company which would provide to such holder rights with respect to the registration of such securities under the Securities Act or the Exchange Act that would conflict with or adversely affect any of the rights provided to the Investors in this Section 2; it being understood and agreed that any subsequent agreement of the Company with any holder or prospective holder of any securities of the Company of the same class (or convertible into or exchange for securities of the same class) as the Registrable Securities granting such Person rights under this Section 2 equivalent to the rights of the Investors under this Section 2 will not be prohibited by the terms of this Section 2.9.

Section 3.

Miscellaneous

3.1 Amendment. No amendment, alteration or modification of any of the provisions of this Agreement shall be binding unless made in writing and signed by each of the Company and the Investors.

3.2 Injunctive Relief. It is hereby agreed and acknowledged that it shall be impossible to measure in money the damages that would be suffered if the parties fail to comply with any of the obligations herein imposed on them and that in the event of any such failure, an aggrieved Person shall be irreparably damaged and shall not have an adequate remedy at law. Any such

Person shall, therefore, be entitled (in addition to any other remedy to which it may be entitled in law or in equity) to injunctive relief, including, without limitation, specific performance, to enforce such obligations, and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law.

3.3 Notices. All notices required or permitted under this Agreement must be in writing and sent to the address identified below. Notices must be given: (a) by personal delivery, with receipt acknowledged; (b) by email followed by hard copy delivered by the methods under clause (c) or (d); (c) by prepaid certified or registered mail, return receipt requested; or (d) by prepaid reputable overnight delivery service. Notices shall be effective upon receipt. Either party may change its notice address by providing the other party written notice of such change. Notices shall be delivered as follows:

3.4 Governing Law; Jurisdiction; Venue; Jury Trial.

(a) This Agreement shall be governed by, and construed in accordance with, the law of the State of New York without giving effect to any choice or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York.

(b) Each of the Company and the Investors irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the courts of the State of New York sitting in the Borough of Manhattan, New York and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement and the transactions contemplated herein, or for recognition or enforcement of any judgment, and each of the Company and the Investors irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York state court or, to the fullest extent permitted by applicable law, in such federal court. Each of the Company and the Investors hereto agrees that a

final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(c) Each of the Company and the Investors irrevocably and unconditionally 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 action or proceeding arising out of or relating to this Agreement and the transactions contemplated herein in any court referred to in Section 3.4(b) hereof. Each of the Company and the Investors hereby irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) EACH OF THE COMPANY AND THE INVESTORS HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH OF THE COMPANY AND THE INVESTORS (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT EACH OF THE COMPANY AND THE INVESTORS HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

3.5 Successors, Assigns and Transferees. Any and all rights, duties and obligations hereunder shall not be assigned, transferred, delegated or sublicensed by any party hereto without the prior written consent of the other party; provided, however, that the Investors shall be entitled to transfer Registrable Securities to one or more of their affiliates and, solely in connection therewith, may assign their rights hereunder in respect of such transferred Registrable Securities to one or more of their affiliates, in each case, so long as such Investor is not relieved of any liability or obligations hereunder, without the prior consent of the Company. Any transfer or assignment made other than as provided in the first sentence of this Section 3.5 shall be null and void. Subject to the foregoing and except as otherwise provided herein, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the successors, permitted assigns, heirs, executors and administrators of the parties hereto. The Company shall not consummate any recapitalization, merger, consolidation, reorganization or other similar transaction whereby stockholders of the Company receive (either directly, through an exchange, via dividend from the Company or otherwise) equity (the “Other Equity”) in any other entity (the “Other Entity”) with respect to Registrable Securities hereunder, unless prior to the consummation thereof, the Other Entity assumes, by written instrument, the obligations under this Agreement with respect to such Other Equity as if such Other Equity were Registrable Securities hereunder, provided, that such Other Entity shall not be required to assume such obligations if, upon consummation of such transaction, the Investors would be able to resell the Other Equity without limitations as to volume or manner of sales pursuant to Rule 144.

3.6 Entire Agreement. This Agreement, together with any exhibits hereto, constitute the entire agreement between the parties relating to the subject matter hereof and all previous agreements or arrangements between the parties, written or oral, relating to the subject matter hereof are superseded.

3.7 Waiver. No failure on the part of either party hereto to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of either party hereto in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver thereof; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy.

3.8 Severability. If any part of this Agreement is declared invalid or unenforceable by any court of competent jurisdiction, such declaration shall not affect the remainder of the Agreement and the invalidated provision shall be revised in a manner that shall render such provision valid while preserving the parties’ original intent to the maximum extent possible.

3.9 Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement. All references in this Agreement to sections, paragraphs and exhibits shall, unless otherwise provided, refer to sections and paragraphs hereof and exhibits attached hereto.

3.10 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be enforceable against the parties that execute such counterparts (including by facsimile or other electronic means), and all of which together shall constitute one instrument.

3.11 Term and Termination. The Investors’ rights to demand the registration of the Registrable Securities under this Agreement, as well as the Company’s obligations hereunder other than pursuant to Section 2.6 hereof, shall (a) be temporarily suspended if, at any time after the Investors could reasonably be deemed to be an affiliate of the Company, the Investors could no longer reasonably be deemed to be affiliate and such Registrable Securities may be resold by the Investor holding such Registrable Securities without limitations as to volume or manner of sale pursuant to Rule 144 (which rights and obligations shall be reinstated at such time as the Investors could reasonably be deemed to be affiliate) and (b) terminate automatically once all Registrable Securities cease to be Registrable Securities pursuant to the terms of this Agreement. For purposes of this Section 3.11, the term “affiliate” shall have the same meaning as such term is defined and used in Rule 144 (including for determining whether volume or manner of sale limitations of Rule 144 apply) and the parties will assume that all convertible securities (whether equity, debt or otherwise) owned by the Investors (but not those of any other person) have been converted into Common Stock.
