Promptly following the execution of this Agreement, Company’s Board of Directors (the “Board”) and all applicable committees of the Board shall take all action necessary to appoint Chris Eberle (the “Designee”) as a Class III director of Company with a term expiring at Company’s 2024 Annual Meeting of Stockholders (the “2024 Meeting”).

2.          Compliance with Laws and Company Policies.

4.          Director Benefits. The Designee will be entitled to the same director benefits as other members of the Board, including (a) compensation for his service as a director and reimbursement for his expenses on the same basis as all other non-employee directors of Company, and (b) the same rights of indemnification and directors’ and officers’ liability insurance coverage as the other non-employee directors of Company as such rights may exist from time to time.

5.          Recusal of the Designee. The Sylebra Group acknowledges that the Board or any of its committees may recuse the Designee from any Board or committee meeting or portion thereof at which the Board or such committee is evaluating or taking action with respect to (a) the exercise of any of Company’s rights or enforcement of any of the obligations under this Agreement; (b) any action taken in response to actions taken or proposed by any member of the Sylebra Group with respect to Company; or (c) any proposed transaction between Company and any member of the Sylebra Group.

15.          Termination.  In the event shares beneficially owned by the Sylebra Group represent less than 9.0% of the outstanding shares of the Company, the Company shall have the right but not the obligation to request the resignation of Designee and Sylebra hereby agrees to cause Designee to resign within five business days of such request.  Sylebra shall only have the right to terminate this Agreement upon (a) the resignation of the Designee from the Board and (b) delivery to Company of advance written notice of such termination at least five business days prior to the date of such termination. Company shall have the right to terminate this Agreement upon delivery to Sylebra of advance written notice of such termination at least five business days prior to the date of such termination. Each of paragraph 3 and paragraphs 16 through 25 shall survive the termination of this Agreement to the extent permitted under applicable law.

16.          Specific Performance. Each Party acknowledges and agrees that money damages would not be a sufficient remedy for any breach (or threatened breach) of this Agreement by it and that, in the event of any breach or threatened breach of this Agreement, (a) the Party seeking specific performance will be entitled to injunctive and other equitable relief, without proof of actual damages; (b) the Party against whom specific performance is sought will not plead in defense that there would be an adequate remedy at law; and (c) the Party against whom specific performance is sought agrees to waive any applicable right or requirement that a bond be posted. Such remedies will not be the exclusive remedies for a breach of this Agreement, but will be in addition to all other remedies available at law or in equity.

17.          Entire Agreement; Binding Nature; Assignment; Waiver. This Agreement, including all exhibits hereto, constitutes the only agreement between the Parties with respect to the subject matter of this Agreement and it supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written. This Agreement binds, and will inure to the benefit, of the Parties and their respective successors and permitted assigns. No Party may assign or otherwise transfer either this Agreement or any of its rights, interests, or obligations under this Agreement without the prior written approval of the other Party. Any purported transfer requiring consent without such consent is void. No amendment, modification, supplement or waiver of any provision of this Agreement will be effective unless it is in writing and signed by the affected Party, and then only in the specific instance and for the specific purpose stated in such writing. Any waiver by any Party of a breach of any provision of this Agreement will not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Agreement. The failure of a Party to insist upon strict adherence to any term of this Agreement on one or more occasions will not be considered a waiver or deprive that Party of the right to insist upon strict adherence to that term or any other term of this Agreement in the future.

18.          Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, then the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement that is held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable, and this Agreement will otherwise be construed so as to effectuate the original intention of the Parties reflected in this Agreement. The Parties further agree to replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the purposes of such invalid or unenforceable provision.

19.          Governing Law; Forum. This Agreement is governed by and will be construed in accordance with the laws of the State of Delaware. Each of the Parties (a) irrevocably and unconditionally consents to the exclusive personal jurisdiction and venue of the Court of Chancery of the State of Delaware and any appellate court thereof (unless the federal courts have exclusive jurisdiction over the matter, in which case the United States District Court for the District of Delaware and any appellate court thereof will have exclusive personal jurisdiction) for any lawsuit, claim or proceeding before any court (each, “Legal Proceeding”) arising out of or related to this Agreement; (b) agrees that it will not attempt to deny or defeat such personal jurisdiction with respect to any Legal Proceeding by motion or other request for leave from any such court; (c) agrees that it will not bring any Legal Proceeding arising out of or relating to this Agreement or otherwise in any court other than the such courts; and (d) waives any claim of improper venue or any claim that those courts are an inconvenient forum for any Legal Proceeding arising out of or related to this Agreement. The Parties agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in paragraph 23 or in such other manner as may be permitted by applicable law, will be valid and sufficient service thereof.

20.          Waiver of Jury Trial. EACH OF THE PARTIES, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY RELATED INSTRUMENT OR AGREEMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREBY, OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTIONS OF ANY OF THEM. No Party will seek to consolidate, by counterclaim or otherwise, any action arising out of or related to this Agreement in which a jury trial has been waived with any other action in which a jury trial cannot be or has not been waived.

21.          Third Party Beneficiaries. This Agreement is solely for the benefit of the Parties and is not enforceable by any other Person.

22.          Notices. All notices, consents, requests, instructions, approvals and other communications provided for in, and all legal process in regard to, this Agreement will be in writing and will be deemed validly given, made or served (a) upon receipt, when delivered personally; (b) upon confirmation of receipt, when sent by email (but only if such confirmation is not automatically generated); or (c) one business day after deposit with a nationally recognized overnight delivery service.
