NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree as follows: 
 1. Elimination of Restrictions on Demand Registrations. Subject to Section 2 of this Amendment, the first sentence of Section 9F of the Investor Rights Agreement is hereby deleted in its
entirety. 
 2. Modification to Registration Expenses. The modification provided for in Section 1 of this Amendment
shall be conditioned upon, with respect to the first Demand Registration, the holders of Registrable Securities participating in such Demand Registration reimbursing (or causing the underwriters underwriting such Demand Registration to reimburse)

3. Priority on Demand Registration. Section 9D of the Agreement (as had been previously amended by (1) Section 2.8

deduction of underwriters’ commissions) from the sale of such Registrable Securities in registered public offerings (the “Base Priority”), with the balance of any shares includable in future Demand Registrations to be allocated
solely among Oaktree Registrable Securities and Indigo Registrable Securities. Notwithstanding such priorities, the Oaktree Investors and the Indigo Investors hereby agree that, with respect to the first Demand Registration under this Agreement,
that the Registrable Securities included in such registration shall consist of (x) first, a number of Registrable Securities which, along with shares of Common Stock sold by the Oaktree Investors and Indigo Investors in the overallotment in the
Company’s initial Public Offering, constitutes the Base Priority, and (y) any remaining Oaktree Registrable Securities and Indigo Registrable Securities included in such Demand Registration, and any shares of Common Stock held by the
Company’s employees or directors designated by the Indigo Investors or the Oaktree Investors to be included in such first Demand Registration (“Additional Shares”), pro rata among the holders of such Registrable Securities or
Additional Shares, as the case may be, on the basis of the number of such shares of Registrable Securities or Common Stock, as the case may be, owned by each such holder; provided, however, that the inclusion any Additional Shares in
such Demand Registration shall be conditioned upon each holder of Additional Shares (1) agreeing in writing to be bound by the Investor Rights Agreement and (2) executing a lock-up agreement for the benefit of the underwriters that is
substantially similar to any lock-up agreement executed by the Indigo Investors and the Oaktree Investors (or their respective designees). 
 4. Successors and Assigns. Section 19F of the Investor Rights Agreement is hereby amended and restated in its entirety as follows: 

 

	 	19F.	 Successors and Assigns. Except as otherwise provided herein, this Agreement shall bind and inure to the benefit of and be enforceable by the
Company and its successors and assigns and the Investors and any subsequent holders of Subject Securities and the respective successors and assigns of each of them; provided, however, that in no case shall the rights to Demand
Registration under Section 9 of this Agreement or Piggyback Registration under Section 10 of this Agreement (or 



  
 2 








	 	
any rights appurtenant thereto) be for the benefit of or made available to any successors or assigns if the Subject Securities held by such successor or assign may be resold under Rule 144 within
a 90-day period, unless such Subject Securities are: (i) Indigo Registrable Securities held directly by an Indigo Investor or a Person designated in writing to the Company by such Indigo Investor; or (ii) Oaktree Registrable Securities
held directly by an Oaktree Investors or a Person designated in writing to the Company by such Oaktree Investor.
