Section 5.12. Governing Law. This Agreement is governed by and will be construed in accordance with the laws of the State of Delaware, excluding any conflict-of-laws rule or principle (whether of Delaware or any other jurisdiction) that might refer the governance or the construction of this Agreement to the law of another jurisdiction.

Section 5.13. Jurisdiction. Each of the Parties (a) consents to submit itself to the personal jurisdiction of the Court of Chancery of the State of Delaware in the event any dispute arises out of this Agreement, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from such court and (c) agrees that it will not bring any action relating to this Agreement or any of the transactions contemplated by this Agreement in any court other than the Court of Chancery of the State of Delaware.

Each Party hereby agrees that, to the fullest extent permitted by law, service of any process, summons, notice or document by U.S. registered mail to the respective addresses set forth in Section 5.11 shall be effective service of process for any suit or proceeding in connection with this Agreement.

Section 5.14. Waiver of Jury Trial. EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF THE PARTIES IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT THEREOF. The Company or any Stockholder may file an original counterpart or a copy of this Section 5.14 with any court as written evidence of the consent of any of the Parties to the waiver of their rights to trial by jury.

Section 5.15. Specific Performance. It is hereby agreed and acknowledged that it will be impossible to measure the money damages that would be suffered if the Parties fail to comply with any of the obligations imposed on them by this Agreement and that, in the event of any such failure, an aggrieved party will be irreparably damaged and will not have an adequate remedy at law. Each party shall, therefore, be entitled (in addition to any other remedy to which such party may be entitled at law or in equity) to seek injunctive relief, including specific performance, to enforce such obligations, without the posting of any bond, and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties shall raise the defense that there is an adequate remedy at law.

Section 5.16. Marketing Materials. The Company grants each of the Stockholders and their respective Affiliates permission to use the Company’s name and logo in marketing materials of such Stockholder or any of its Affiliates. The Stockholders and their respective Affiliates, as applicable, shall include a trademark attribution notice giving notice of the Company’s ownership of its trademarks in the marketing materials in which the Company’s name and logo appear.

Section 5.17. Adjustments. All references in this Agreement to Company Shares shall be appropriately adjusted for any stock dividends, splits, reverse splits, combinations, reclassifications, recapitalizations, reorganizations and the like occurring after the date hereof.

Section 5.18. No Third Party Beneficiaries. Except as specifically provided in Section 5.02 and as otherwise provided herein, this Agreement is not intended to confer upon any Person, except for the parties, any rights or remedies hereunder.

Section 5.19. Indemnification. The Company will indemnify, exonerate and hold the Stockholders and each of their respective partners, stockholders, members, directors, officers, fiduciaries, managers, controlling Persons, employees and agents of each of the partners, stockholders, members, directors, officers, fiduciaries, managers, controlling Persons, employees and agents of each of the foregoing (collectively, the “Indemnified Parties”) free and harmless from and against any and all actions, causes of action, suits, claims, liabilities, losses, damages and costs and other out-of-pocket expenses in connection therewith (including reasonable attorneys’ fees and expenses) incurred by the Indemnified Parties or any of them before or after the date of this Agreement (collectively, the “Indemnified Liabilities”), arising out of any actual or threatened action, cause of action, suit, or claim arising directly or indirectly out of such Institutional Stockholder’s or its other Indemnified Party’s actual, alleged or deemed control or ability to influence the Company or any of its subsidiaries or the actual or alleged act or omission of such Stockholder’s Director nominee(s) including for any alleged act or omission arising out of or in connection with the IPO (other than any such Indemnified Liabilities that arise out of any breach of this Agreement by such Indemnified Party or other related Persons); provided that if and to the extent that the foregoing undertaking may be unavailable or unenforceable for any reason, the Company hereby agrees to make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. The rights of any Indemnified Party to indemnification hereunder will be in addition to any other rights any such Person may have under any other agreement or instruction to which such Indemnified Party is or becomes a party or is or otherwise becomes a beneficiary or under law or regulation or under the Governing Documents of the Company or constitutive documents of any of its subsidiaries and shall extend to such Indemnified Party’s successors and assigns. Each of the Indemnified Parties shall be a third party beneficiary of the rights conferred to such Indemnified Party in this Section 5.20.
