terms below. 
 3.1 Right of First Negotiation 

(i) Bridge hereby grants to the Company a right of first negotiation during the Exclusivity Period (“ROFN”) with respect to
the Offered Assets as set forth in this Section 3.1. Subject to the exclusivity restriction set forth in Section 2, if, at any time within the Exclusivity Period, Bridge or its Affiliate intends to
engage in any Transaction, Bridge shall promptly notify the Company in writing of such intent, together with any information and data generated by, or on behalf of, Bridge or such Affiliate regarding the financial terms of such Transaction, a
description of the 

  
 4 













 
Offered Assets and such other material information regarding such Transaction and the Offered Assets as would be reasonably useful for the Company to determine its interest in such Transaction
(“ROFN Offer Notice”). Upon the Company’s written request, Bridge shall promptly, and in any case within [***] of receipt of such request, provide any additional information with respect to the Transaction or the Offered Assets
reasonably requested by the Company. Within [***] from the receipt of the ROFN Offer Notice (“ROFN Exercise Period”), the Company may exercise its ROFN by providing Bridge with a written notice of its intent to exercise its ROFN
(the “ROFN Exercise Notice”). Upon Bridge’s receipt of such ROFN Exercise Notice, Bridge shall, or shall cause the applicable Affiliate to, exclusively negotiate in good faith with the Company or its Affiliate for a period of [***]
from the date of the ROFN Exercise Notice, unless such negotiations are earlier terminated by the Company (the “ROFN Negotiation Period”) the terms of the Transaction upon which the parties would enter into a definitive agreement at a
price and on terms mutually agreed between the parties. 
 (ii) If (a) the Company notifies Bridge prior to the expiration of the ROFN
Exercise Period that the Company elects not to exercise its ROFN, (b) the Company does not provide Bridge with a ROFN Exercise Notice within the ROFN Exercise Period, or (c) the Company provides Bridge with a ROFN Exercise Notice within
the ROFN Exercise Period but the Parties fail to reach a definitive agreement on the terms of the Transaction during the ROFN Negotiation Period, the ROFN will expire on the applicable expiration date (“ROFN Expiration”, with respect to
(a), on the date on which the Company notifies Bridge of its intent not to Exercise the ROFN; with respect to (b), on the expiration date of the ROFN Exercise Period; and with respect to (c), on the expiration date of the ROFN Negotiation Period),
and Bridge shall be free to pursue the Transaction with any third party, provided, that the terms of such Transaction with the third party shall not be, taken as a whole, more favorable to such third party than the last written offer proposed
by the Company during the ROFN Negotiation Period. No less than [***] prior to entering into a definitive agreement for any such Transaction with the third party, Bridge shall provide a written notice to the Company describing such Transaction in
reasonable detail, including but not limited to (x) the identity of the third party, and (y) a description of the financial and other material terms proposed by the third party. The Company may, at its sole discretion, pursue such
Transaction in competition with the third party and, in such event, Bridge shall negotiate with Company in good faith unless and until Bridge or its Affiliates have entered into definitive agreements with such third party. 

(iii) Notwithstanding anything to the contrary, the Parties agree that the ROFN shall automatically renew if Bridge does not enter into a
definitive agreement for the Transaction with a third party as described in Section 3.1(ii) above within [***] after the then most-recent ROFN Expiration; provided, however, for the avoidance of doubt, that in no
event shall the Exclusivity Period be extended by this Section 3.1(iii) and the ROFN shall not extend beyond the Exclusivity Period. 

3.2 Rights of First Refusal 

(i) Bridge hereby grants to the Company a right of first refusal during the Exclusivity Period (“ROFR”) with respect to any
proposed Transaction relating to an Offered Asset as set forth in this Section 3.2. Subject to the exclusivity restriction set forth in Section 2, if, at any time within the Exclusivity Period,
Bridge or its Affiliate receives a bona fide offer from a third party with respect to a Transaction (“ROFR Offer”), Bridge shall promptly give the Company a written notice of such ROFR Offer detailing the terms of such ROFR Offer,
including but not limited to (a) the identity of the third party offeror, (b) a description of the financial and other material terms proposed by the third party offeror, including a description of the Offered Asset(s) subject to such ROFR
Offer, and (c) such other material terms and information regarding the ROFR Offer or the Offered Asset(s) generated by, or on behalf of, Bridge that would be reasonably useful for the Company to determine its interest in the Transaction
(“ROFR Offer Notice”), and offer the Company the right to step in and consummate the Transaction on substantially the same terms as set forth in the ROFR Offer Notice. 

  
 5 













 
Upon the Company’s written request, Bridge shall promptly, and in any case within [***] of receipt of such request, provide any additional information with respect to the ROFR Offer or the
Offered Assets reasonably requested by the Company. Within [***] from the receipt of the ROFR Offer Notice (“ROFR Exercise Period”), the Company may exercise its ROFR by providing Bridge with a written notice of its intent thereto
(the “ROFR Exercise Notice”). Upon Bridge’s receipt of such ROFR Exercise Notice, Bridge shall, or shall cause its Affiliate to negotiate in good faith with the Company or its Affiliate(s) for a period no less than [***] from
the date of the ROFR Exercise Notice , unless such negotiations are earlier terminated by the Company (the “ROFR Negotiation Period”) the terms of a definitive agreement for such Transaction and the Parties shall enter into the
definitive agreement based on substantially the same terms as the ROFR Offer. 
 (ii) If (a) the Company notifies Bridge prior to the
expiration of the ROFR Exercise Period that the Company elects not to exercise its ROFR, (b) the Company does not provide Bridge with a ROFR Exercise Notice within the ROFR Exercise Period, or (c) the Company provides Bridge with a ROFR
Exercise Notice within the ROFR Exercise Period but the Parties fail to reach a definitive agreement on the terms of the Transaction during the ROFR Negotiation Period, the ROFR will expire on the applicable expiration date (“ROFR
Expiration”, with respect to (a), on the date on which the Company notifies Bridge of its intention not to exercise the ROFR; with respect to (b), the expiration of the ROFR Exercise Period; and with respect to (c), on the expiration date of
the ROFR Negotiation Period), and Bridge shall be free to pursue the Transaction with any third party, provided, that the terms of such Transaction with the third party shall not be, taken as a whole, more favorable to such third party than
any offer from the Company. 
 (iii) Notwithstanding anything to the contrary, the Parties agree that the ROFR shall automatically renew if
Bridge does not enter into a definitive agreement for the Transaction with a third party as described in Section 3.2(ii) above within [***] after the then most-recent ROFR Expiration; provided, however, for the
avoidance of doubt, that in no event shall the Exclusivity Period be extended by this Section 3.2(iii) and the ROFR shall not extend beyond the Exclusivity Period. 

 

	4.	 No Definitive Obligation 



The Parties agree that no contract, agreement or commitment with respect to a Transaction or any other transaction shall exist or be deemed to
exist by virtue of this Agreement, any other written or oral expression with respect to a Transaction or otherwise unless and until a definitive agreement related thereto has been duly executed and delivered. The Parties also agree that, unless and
until such a definitive agreement has been duly executed and delivered, none of the Parties or its respective Representatives shall have any liability or obligation with respect to a Transaction or any other transaction, whether by virtue of this
Agreement, any other written or oral expression with respect to a Transaction or otherwise, except for the obligations of the Parties expressly set forth in this Agreement. For purposes of this Agreement, the term “definitive agreement”
shall not include any written or oral acceptance of any offer or bid, any term sheet or any letter of intent or other written expression of either Party’s intention to negotiate or enter into a definitive agreement. 

 

	5.	 Miscellaneous

Dispute to the other Party, Section 5.5(ii) shall apply. 
 (ii) In the event the Parties are unable to settle a Dispute in accordance
with Section 5.5(i) above, such Dispute shall be referred to and conclusively determined by arbitration upon the demand of either Party to the dispute with notice (the “Arbitration Notice”) to the other.

the Respondent shall be limited in their selection to any prescribed list. The selected arbitrators shall collectively select the third arbitrator who will act as chairman of the arbitration board. 

(v) The arbitral proceedings shall be conducted in English. To the extent that the ICC Rules are in conflict with the provisions of this
Section 5.5, including the provisions concerning the appointment of the arbitrators, the provisions of this Section 5.5 shall prevail.

 5.6 Notices. Any notice required or permitted pursuant to this Agreement shall be given in writing and shall be given either
personally or by sending it by next-day or second-day courier service, fax, electronic mail or similar means to the address of the relevant Party set forth in the
signature pages hereto (or at such other address as such Party may designate by [***] advance written notice to the other Parties to this Agreement given in accordance with this Section 5.6). Where a notice is sent by next-day or second-day courier service, service of the notice shall be deemed to be effected by properly addressing, pre-paying and
sending by next-day or second-day service through an internationally-recognized courier a letter containing the notice, with a written confirmation of delivery, and to
have been effected at the earlier of (i) delivery (or when delivery is refused) and (ii) expiration of [***] after the letter containing the same is sent as aforesaid. Where a notice is sent by fax or electronic mail, service of the notice
shall be deemed to be effected by properly addressing, and sending such notice through a transmitting organization, with a written confirmation of delivery, and to have been effected on the day the same is sent as aforesaid, if such day is a

Performance. Each and all of the various rights, powers and remedies of a Party hereto will be considered to be cumulative with and in addition to any other rights, powers and remedies which such Party may have at Law or in equity in the
event of the breach of any of the terms of this Agreement. The exercise or partial exercise of any right, power or remedy will neither constitute the exclusive election thereof nor the waiver of any other right, power or remedy available to such
Party. Without limiting the foregoing, the Parties hereto acknowledge and agree irreparable harm may occur for which money damages would not be an adequate remedy in the event that any of the provisions of this Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement.

 5.8 Severability. In case any provision of the Agreement shall be invalid, illegal or unenforceable, the validity, legality
and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. If, however, any provision of this Agreement shall be invalid, illegal, or unenforceable under any such applicable Law in any jurisdiction, it
shall, as to such jurisdiction, be deemed modified to conform to the minimum requirements of such Law, or, if for any reason it is not deemed so modified, it shall be invalid, illegal, or unenforceable only to the extent of such invalidity,
illegality, or limitation on enforceability without affecting the remaining provisions of this Agreement, or the validity, legality, or enforceability of such provision in any other jurisdiction. 

  
 8 













 5.9 Amendments and Waivers. Any provision in this Agreement may be amended or
waived, only by the written consent of both Parties. Notwithstanding the foregoing, any Party hereunder may waive any of its rights hereunder without obtaining the consent of the other Party. Any amendment or waiver effected in accordance with this
Section shall be binding upon all the Parties hereto. 
 5.10 Delays or Omissions. No delay or omission to exercise any right, power
or remedy accruing to any Party under this Agreement, upon any breach or default of any other Party under this Agreement, shall impair any such right, power or remedy of such non-breaching or non-defaulting Party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any Party of any breach or default under this Agreement,
or any waiver on the part of any Party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. 

5.11 No Presumption. The Parties acknowledge that any applicable Law that would require interpretation of any claimed ambiguities
in this Agreement against the Party that drafted it has no application and is expressly waived. If any claim is made by a Party relating to any conflict, omission or ambiguity in the provisions of this Agreement, no presumption or burden of proof or
persuasion will be implied because this Agreement was prepared by or at the request of any Party or its counsel. 
 5.12
Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Facsimile and e-mailed copies of signatures shall be deemed to be originals for purposes of the effectiveness of this Agreement.

of any of the Charter Documents for any of the Parties, or in the event of any dispute related to any such Charter Document, the terms of this Agreement shall prevail in all respects as between the shareholders of the Company
only, the Parties shall give full effect to and act in accordance with the provisions of this Agreement over the provisions of such Charter Documents, and the Parties hereto shall exercise all voting and other rights and
powers (including to procure any required alteration to such Charter Documents to resolve such conflict or inconsistency) to make the provisions of this Agreement effective, and not to take any actions that impair any provisions in
this Agreement.
