REPRESENTATIONS AND WARRANTIES

Each Company Stockholder represents and warrants as of the date hereof to dMY and the Company (solely with respect to itself, himself or herself and not with respect to any other Company Stockholder) as follows:

Section 2.1 Organization; Due Authorization. If such Company Stockholder is not an individual, it is duly organized, validly existing and in good standing under the Laws of the jurisdiction in which it is incorporated, formed, organized or constituted, and the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby are within such Company Stockholder’s corporate, limited liability company or organizational powers and have been duly authorized by all necessary corporate, limited liability company or organizational actions on the part of such Company Stockholder.

Section 2.3 No Conflicts. The execution and delivery of this Agreement by such Company Stockholder does not, and the performance by such Company Stockholder of his, her or its obligations hereunder will not, (i) if such Company Stockholder is not an individual, conflict with or result in a violation of the organizational documents of such Company Stockholder, (ii) require any consent or approval that has not been given or other action that has not been taken by any Person (including under any Contract binding upon such Company Stockholder or such Company Stockholder’s Subject Shares), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Company Stockholder of its, his or her obligations under this Agreement or (iii) conflict with or violate any Law.

Section 2.4 Litigation. There are no Proceedings pending against such Company Stockholder, or to the knowledge of such Company Stockholder threatened against such Company Stockholder, before (or, in the case of threatened Proceedings, that would be before) any arbitrator or any Governmental Entity, which in any manner challenges or seeks to prevent, enjoin or materially delay the performance by such Company Stockholder of such Company Stockholder’s obligations under this Agreement.

Section 2.5 Adequate Information. Such Company Stockholder is a sophisticated stockholder and has adequate information concerning the business and financial condition of dMY and the Company to make an informed decision regarding this Agreement and the Transactions and has independently and without reliance upon dMY or the Company and based on such information as such Company Stockholder has deemed appropriate, made its own analysis and decision to enter into this Agreement.

Upon such termination of this Agreement, all obligations of the parties under this Agreement will terminate, without any liability or other obligation on the part of any party hereto to any Person in respect hereof or the transactions contemplated hereby, and no party hereto shall have any claim against another (and no person shall have any rights against such party), whether under contract, tort or otherwise, with respect to the subject matter hereof; provided, however, that the termination of this Agreement shall not relieve any party hereto from liability arising in respect of any breach of this Agreement prior to such termination. This ARTICLE III shall survive the termination of this Agreement.

5

Section 3.2 Governing Law. The Law of the State of Delaware shall govern (a) all claims or matters related to or arising from this Agreement (including any tort or non-contractual claims) and (b) any questions concerning the construction, interpretation, validity and enforceability of this Agreement, and the performance of the obligations imposed by this Agreement, in each case without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Law of any jurisdiction other than the State of Delaware.

Section 3.3 CONSENT TO JURISDICTION AND SERVICE OF PROCESS; WAIVER OF JURY TRIAL.

(a) Each party hereto submits to the exclusive jurisdiction of first, the Court of Chancery of the State of Delaware or if such court declines jurisdiction, then to any court of the State of Delaware or the Federal District Court for the District of Delaware, in any Proceeding arising out of or relating to this Agreement, agrees that all claims in respect of the Proceeding shall be heard and determined in any such court and agrees not to bring any Proceeding arising out of or relating to this Agreement in any other courts. Nothing in this Section 3.3, however, shall affect the right of any party to serve legal process in any other manner permitted by Law or at equity. Each party hereto agrees that a final judgment in any Proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by Law or at equity.

(b) WAIVER OF TRIAL BY JURY. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE BETWEEN OR AMONG ANY OF THE PARTIES (WHETHER ARISING IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS AGREEMENT, THE TRANSACTIONS OR THE RELATIONSHIPS ESTABLISHED AMONG THE PARTIES UNDER THIS AGREEMENT. EACH PARTY FURTHER WARRANTS AND REPRESENTS THAT SUCH PARTY HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT SUCH PARTY KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL.

Section 3.4 Assignment. This Agreement and all of the provisions hereof will be binding upon and inure to the benefit of the parties hereto and their respective heirs, successors and permitted assigns. Neither this Agreement nor any of the rights, interests or obligations hereunder will be assigned (including by operation of law) without the prior written consent of the parties hereto. Any purported assignment or delegation not permitted under this Section 3.4 shall be null and void.

Section 3.5 Specific Performance. The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof and that the parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or in equity without the necessity of proving the inadequacy of money damages as a remedy and without bond or other security being required, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereto hereby further acknowledges that the existence of any other remedy contemplated by this Agreement does not diminish the availability of specific performance of the obligations hereunder or any other injunctive relief. It is accordingly agreed that the parties hereto shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the chancery court or any other state or federal court within the State of Delaware, this being in addition to any other remedy to which such party is entitled at law or in equity. Each party hereto hereby further agrees that in the event of any action by any other party for specific performance or injunctive relief, it will not assert that a remedy at law or other remedy would be adequate or that specific performance or injunctive relief in respect of such breach or violation should not be available on the grounds that money damages are adequate or any other grounds.

Section 3.6 Amendment; Waiver. This Agreement may not be amended, changed, supplemented, waived or otherwise modified or terminated, except upon the execution and delivery of a written agreement executed by dMY, the Company and the Company Stockholders that collectively hold a number of Subject Shares required to authorize the Company Stockholder Approval.

Section 3.7 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable Law, but if any provision of this Agreement or the application of any such provision to any Person or circumstance shall be held to be prohibited by or invalid, illegal or unenforceable under applicable Law in any respect by a court of competent jurisdiction, such provision shall be ineffective only to the extent of such prohibition or invalidity, illegality or unenforceability, without invalidating the remainder of such provision or the remaining provisions of this Agreement. Furthermore, in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid, or unenforceable provision as may be possible.

Section 3.8 Release of Claims. In consideration for the payments and other benefits to be received by the Company Stockholder under the terms of the Merger Agreement, subject to and effective as of the Closing, the Company Stockholder, for and on behalf of himself, herself or itself and each of his, her or its, as applicable, heirs, executors, administrators, personal representatives, successors, assigns, subsidiaries, predecessors, parent companies, shareholders and Affiliates and in each case, each of their respective Affiliates, officers, directors, partners, employees, agents, attorneys, and other representatives, hereby acknowledges full and complete satisfaction of and fully and irrevocably releases and forever discharges the Company, dMY (and, for the avoidance of doubt, the Trust Account), each of their respective subsidiaries and their predecessors, successors, assignees, parent companies, shareholders and investors (direct and indirect) and, in each case, each of their respective Affiliates, officers, directors, partners, employees, agents, attorneys and other representatives, past and present (collectively, the “Released Entities”), from liability on or for any and all charges, claims, controversies, actions, causes of action, cross claims, counterclaims, demands, debts, duties, sanctions, fines, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs, attorney’s fees, sums of money, suits, contracts, covenants, controversies, agreements, promises, responsibilities, obligations and accounts of any kind, nature or description whatsoever in Law or in equity (“Actions”), direct or indirect, past, present and future, and whether or not now or heretofore known, suspected, matured or unmatured, contingent or uncontingent, or claimed against the Released Entities, through and including the Closing, in each case solely to the extent that it arises out of, or is related to, (i) such Company Stockholder’s ownership of equity or debt interests in the Company prior to the Closing (including any and all Actions such Company Stockholder may have against the Released Entities in such Company Stockholder’s capacity as a securityholder or a debtholder of the Company) and (ii) the organization, management or operation of the businesses of the Company relating to any matter, occurrence, action, inaction, omission or activity prior to the Closing, in each case, solely in such Company Stockholder’s capacity as an equity or debt securityholder; provided, that such release shall not release the Released Entities for (i) any liabilities or Actions that such Company Stockholder has pursuant to its right to receive its portion of the Company Equity Value determined in accordance with, and subject to, the terms of, and the steps set forth in, the Merger Agreement, (ii) any Actions arising out of or related to the Released Entities’ respective governing documents to provide indemnification, reimbursement or advancement of expenses to such Company Stockholder in respect of actions taken or omitted in such Company Stockholder’s capacity as an officer and/or director of such Released Entity prior to the Closing, (iii) any Actions arising out of or related to the Released Entities’ contracts with or obligations to any Company Stockholder in respect of compensation arrangements as an officer and/or director of such Released Entity prior to the Closing or (iv) any Actions arising under, or in connection with, any commercial agreements as between any direct or indirect portfolio companies of the Company Stockholder or its Affiliates and any Released Entity.
