No amendment or repeal of this Article Eleven shall apply to or have any effect on the liability or alleged liability of any Non-Employee Director for or with respect to any opportunities of which such Non-Employee Director becomes aware prior to such amendment or repeal.

ARTICLE TWELVE

To the fullest extent permitted by the General Corporation Law of the State of Delaware, as the same exists or may hereafter be amended, a director of the Corporation shall not be liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director. Any amendment, modification or repeal of this Article Twelve shall not adversely affect any right or protection of a director of the Corporation that exists at the time of such amendment, modification or repeal. The Corporation shall, to the fullest extent permitted under the General Corporation Law of the State of Delaware, as the same exists or may hereafter be amended, indemnify and upon request shall advance expenses to any person who is involved (including, without limitation, as a witness) or is or was a party or is threatened to be made a party to any threatened, pending or completed action, suit, proceeding or claim, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was or has agreed to be a director or officer of the Corporation or, while a director or officer, is or was serving at the request of the Corporation as a director, officer, partner, trustee, employee or agent (or in any other capacity while so serving) of any corporation, partnership, joint venture, trust or other enterprise (an “indemnitee”), including service with respect to employee benefit plans, against all expenses (including attorney’s fees and expenses), liabilities, losses, judgments, fines, penalties, excise taxes or penalties under the Employee Retirement Income Security Act of 1974, as amended from time to time (“ERISA”), and amounts paid in settlement incurred or suffered in connection with the investigation, preparation to defend or defense of such action, suit, proceeding or claim, and such indemnification shall continue as to a person who has ceased to be a director or officer of the Corporation; provided, however, that the foregoing shall not require the Corporation to indemnify or advance expenses to any person in connection with any action, suit, proceeding or claim initiated by or on behalf of such person or any counterclaim against the Corporation initiated by or on behalf of such person. Such indemnification shall not be exclusive

of other indemnification rights arising under any by-law, agreement, vote of directors or stockholders or otherwise and shall inure to the benefit of the heirs and legal representatives of such person. Any person seeking indemnification under this Article Twelve shall be deemed to have met the standard of conduct required for such indemnification unless the contrary shall be established. The Corporation hereby acknowledges that certain indemnitees affiliated with institutional investors may have certain rights to indemnification, advancement of expenses and/or insurance provided by such institutional investors or certain of their affiliates (collectively, the “Institutional Indemnitors”). The Corporation hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to the indemnitee are primary and any obligation of the Institutional Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by the indemnitee are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by the indemnitee in accordance with this Article Twelve without regard to any rights the indemnitee may have against the Institutional Indemnitors and (iii) that it irrevocably waives, relinquishes and releases the Institutional Indemnitors from any and all claims against the Institutional Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Corporation further agrees that no advancement or payment by the Institutional Indemnitors on behalf of the indemnitee with respect to any claim for which the indemnitee has sought indemnification from the Corporation shall affect the foregoing and the Institutional Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of the indemnitee against the Corporation. Expenses (including attorneys’ fees, costs and charges) incurred by an indemnitee in defending a proceeding shall be paid by the Corporation in advance of the final disposition of such proceeding upon receipt of an undertaking by or on behalf of the indemnitee to repay all amounts so advanced in the event that it shall ultimately be determined that such indemnitee is not entitled to be indemnified by the Corporation as authorized in this Article Twelve. Any repeal or modification of the foregoing provisions of this Article Twelve shall not adversely affect any right or protection of a director of the Corporation with respect to any acts or omissions of such director occurring prior to such repeal or modification.

Notwithstanding anything to the contrary in the foregoing in this Article Twelve, any present and former (determined as of the Effective Time (as defined in the Agreement and Plan of Merger, dated as of April 9, 2018 (the “Merger Agreement”), by and among the Corporation, Vertex Holdco LLC and Vertex Merger Sub LLC) director or officer of the Corporation shall be provided with the same rights to indemnification (including any rights to the advancement of expenses) permitted under applicable law and the Corporation’s certificate of incorporation and by-laws in effect as of the date of the Merger Agreement in connection with, arising out of or otherwise related to matters existing or occurring at or prior to the Effective Time. If this Article Twelve or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each person entitled to indemnification under the first paragraph of this Article Twelve as to all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, ERISA excise taxes and penalties, penalties and amounts paid or to be paid in settlement) actually and reasonably incurred or suffered by such person and for which indemnification is available to such person pursuant to this Article Twelve to the full extent permitted by any applicable portion of this

Article Twelve that shall not have been invalidated and to the full extent permitted by applicable law.
