7.1 Subject to the limitations and other provisions of this Agreement, each Group Company (each, an “Indemnifying Party”)
hereby agrees to jointly and severally indemnify and hold harmless the Series F Investor, and the Series F Investor’s Affiliates, directors, officers, agents and assigns (the Series F Investor together with its Affiliates, directors, officers,
agents and assigns collectively, an “Indemnified Party”), from and against any and all Indemnifiable Losses suffered by such Indemnified Party as a result of, or based upon or arising from any inaccuracy in, or breach or non-performance of any of the representations, warranties, covenants or agreements made by the Indemnifying Party contained herein, provided, however, for breach or
non-performance of the covenant as set forth in Section 5.5(d), such obligation to indemnify only applies where the Group Companies are suspended from operation of the Principal
Business, if there is otherwise a Material Adverse Effect on the Company’s Principal Business, or if the Company’s registration statement for an initial public offering is rejected, in each case solely due to such breach or non-performance. For the purpose of this Section 7, “Indemnifiable Loss” means any liability, loss, penalty, damage (excluding, however, without limitation, any indirect,
punitive, or consequential damages (unless such amounts are actually awarded to third parties), or any loss of products, loss of profits or loss of revenue, loss of contracts or loss of goodwill), payment, reasonable out of pocket costs and expense
(including interest and reasonable attorney’s fees, provided, however, “Indemnifiable Loss” shall be net of (a) any insurance or other recoveries payable by the Indemnified Party or its Affiliates in connection with
the facts giving rise to the right of indemnification, (b) any Tax benefit payable by the Indemnified Party or its Affiliates arising in connection with the accrual, incurrence or payment of any such Indemnifiable Losses. 

7.2 Subject to the limitations and other provisions of this Agreement, the right of the Indemnified Party to indemnification shall apply only
to those claims for indemnification under the foregoing Section 7.1 made on or before the respective dates set forth below: 

(a) any claim for indemnification relating to any breach of the representations and warranties contained in Section 4 made by the
Indemnifying Party and/or any other Warrantor contained herein shall be made on or before the date which is twelve (12) months after the Closing Date; provided, however, that (i) no time limit shall apply to any right to
indemnification with respect to the Fundamental Representations or non-performance of any covenants or agreements made by the Indemnifying Party and/or any other Warrantor contained herein, and (ii) any
claim for indemnification with respect to any breach of any representation and warranty contained in Section 4.17 (“Tax Representations”) shall be made on or before the date which is thirty (30) days
after the expiration of the applicable statute of limitations. 
 7.3 An Indemnifying Party shall not be liable for any claim for
indemnification pursuant to this Section 7 unless and until (a) with respect to any individual breach or inaccuracy, the aggregate amount of the Indemnifiable Losses suffered by any Indemnified Party arising from such individual breach or
inaccuracy exceed 0.5% of the Purchase Price; and (b) the aggregate amount of all such Indemnifiable Losses incurred or suffered by the claiming Indemnified Parties (after applying the de minimis threshold contained in clause (a) above)
exceeds 1.5% of the aggregate of the Purchase Price, at which point the Indemnifying Party will indemnify such Indemnified Parties for all such Indemnifiable Losses; provided, however, that (i) the aggregate amount of all
Indemnifiable Losses suffered by an Indemnified Party for which the Indemnifying Parties shall be liable pursuant to this Section 7 for the inaccuracy, breach or non-performance of any representations,
warranties, covenants or agreements shall not exceed 100% of the Purchase Price, and (ii) the Indemnifying Party shall not have any liability under any provision of this Agreement or any other Transaction Documents for any punitive damages,
consequential damages (unless such amount are actually awarded to third parties), or loss of profit. 

  
 26 













 7.4 Restrictions set forth in Section 7.3 above shall not apply to
or otherwise limit any Indemnified Party’s right to seek and obtain any remedy in respect of any claim by such person on account of fraudulent, criminal or intentional misconduct on the part of the Indemnifying Party and/or any other Warrantor.

 7.5 Any Indemnified Party seeking any Indemnifiable Loss shall give written notice to the Indemnifying Party of any matter which such
Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within 30 Business Days of such determination, describing in reasonable detail the facts and circumstances with respect to the subject
matter of such claim or action and stating the amount of the Indemnifiable Loss, if reasonably practicable. Subject to the restrictions set forth in this Section 7, the Indemnifiable Loss shall be payable: (a) upon the resolution of such
claim by mutual agreement between the indemnified Party and the Indemnifying Party; (b) upon the issuance of a definitive order from a governmental authority or a final judgment, award, order or other ruling (which is not subject to appeal or
with respect to which the time for appeal has elapsed) by a court or arbitral tribunal having jurisdiction over the parties and the subject matter of such claim or to which such claim was submitted for resolution by joint agreement between the
indemnified Party and the Indemnifying Party; or (c) upon the final settlement of such claim with a third party upon the Indemnifying Party’s consent (which consent shall not be unreasonably withheld or delayed). 

7.6 The Parties acknowledge and agree that, following the Closing, the indemnification provisions of this Section 7 shall be the sole and
exclusive remedies of the Indemnified Party for any breach by the Indemnifying Party and/or any other Warrantor of any representations and warranties and for any failure by the Indemnifying Party and/or any other Warrantor to perform and comply with
any covenants and agreements in this Agreement (other than claims arising from fraud, criminal activity or willful misconduct on the part of a Indemnifying Party and/or any other Warrantor in connection with the transactions contemplated by this
Agreement). Each Party hereto shall take all reasonable steps to mitigate the Indemnifiable Losses upon and after becoming aware of any event which could reasonably be expected to give rise to any such Indemnifiable Losses. Nothing in this
Section 7.6 shall limit any Party’s right to seek and obtain any equitable relief to which any Party shall be entitled or to seek any remedy on account of any Party’s fraudulent, criminal or intentional misconduct. 

7.7 No Indemnified Party shall be entitled to recover damages or obtain payment, reimbursement, restitution or indemnity more than once in
respect of any Indemnifiable Loss which gives rise to more than one claim which is the subject of this Section 7. 
 7.8 For the
avoidance of doubt, each Indemnifying Party hereby agrees and covenants that (i) it will not challenge or raise a defense to any claim against such Indemnifying Party or the exercise of any right or remedy against such Warrantor (whether under
this Section 7 or any other provision of this Agreement or any other Transaction Document) on the grounds that such claim, right or remedy is not enforceable or permitted by applicable law, and (ii) it will do all such things and undertake
all such actions, including without limitation any applications to and registrations with the governmental authorities and any other protective measures reasonably requested by the Series F Investor, to ensure that the agreement of the parties with
respect to joint and several liability of the Warrantors under the Transaction Documents is given full force and effect.

provided that the Parties shall continue to be bound by the provisions of Sections 8.1, 8.4, 8.10, 8.12, 8.13 and 8.14. Such termination shall be without prejudice to any claims for damages or other remedies
