Such Stockholder shall not make any public announcement regarding this Agreement and the transactions contemplated hereby without the prior written consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed), except as may be required by applicable Law (provided that, other than in the case of an amendment to a Schedule 13D or 13G that discloses this Agreement, reasonable notice of any such disclosure will be provided to Parent). Such Stockholder consents to and hereby authorizes the Company, Parent and Purchaser to publish and disclose in all documents and schedules filed with the SEC, including Schedule 14D-9, and any press release or other disclosure document that Parent, the Company or Purchaser reasonably determines to be necessary in connection with the Offer, the Merger and any of the other Contemplated Transactions, in each case regarding such Stockholder’s identity and ownership of the Subject Shares, the existence of this Agreement, the nature of such Stockholder’s commitments and obligations under this Agreement and any other information that Parent or the Company reasonably determines is required to be disclosed by Law, and such Stockholder acknowledges that Parent and Purchaser may, in Parent’s sole discretion, file this Agreement or a form hereof with the SEC or any other Governmental Body. Such Stockholder agrees to promptly give Parent any information it may reasonably request for the preparation of any such disclosure documents, and such Stockholder agrees to promptly notify Parent of any required corrections with respect to any information supplied by such Stockholder specifically for use in any such disclosure document, if and to the extent it becomes aware that any such information shall have become false or misleading in any material respect.

Section 4.4 Adjustments. In the event of any stock split, stock dividend, merger, reorganization, recapitalization, reclassification, combination, exchange of shares or the like of the capital stock of the Company affecting the Subject Shares, the terms of this Agreement shall apply to the resulting securities.

Each Stockholder hereby agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against the Company, Parent, Purchaser or any of their respective successors, directors or officers relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Merger or the other Contemplated Transactions, including any such claim (a) challenging the validity of, or seeking to enjoin or delay the operation of, any provision of this Agreement or the Merger Agreement (including any claim seeking to enjoin or delay the acceptance of the Offer or the Merger) or (b) alleging a breach of any duty of the Company Board in connection with the Merger Agreement, this Agreement or the transactions contemplated thereby or hereby, but excluding any such claim brought by a Stockholder as a third party beneficiary under Section 9.6 of the Merger Agreement.

Each Stockholder, solely in its capacity as a stockholder of the Company, shall not, and shall direct its Representatives involved in the Contemplated Transactions not to: (i) directly or indirectly initiate, solicit, or knowingly encourage or knowingly facilitate (including by way of providing information or taking any other action) any inquiries, proposals or offers, or the making of any submission or announcement of any inquiry, proposal or offer that constitutes or could reasonably be expected to lead to any Acquisition Proposal, (ii) directly or indirectly engage in, enter into or participate in any discussions or negotiations with any Person with respect to any Acquisition Proposal, (iii) provide any non-public information to, or afford access to the business, properties, assets, books or records of the Company to, any Person (other than Parent, Purchaser, or any designees of Parent or Purchaser) in connection with any Acquisition Proposal, (iv) enter into any agreement in principle, letter of intent, term sheet, merger agreement, purchase agreement, acquisition agreement, option agreement or other similar instrument relating to an Acquisition Proposal, (v) recommend any other holder of Company Common Stock to not tender shares of Company Common Stock in the Offer or (vi) resolve or agree to do any of the foregoing. Each Stockholder shall, and shall direct its Representatives involved in the Contemplated Transactions to, immediately cease any solicitation, discussions, or negotiations with any Person (other than Parent, Purchaser, or any designees of Parent or Purchaser) with respect to any Acquisition Proposal or potential Acquisition Proposal that could reasonably be expected to lead to an Acquisition Proposal. Notwithstanding the foregoing, such Stockholder or its Representative may, solely in response to an inquiry or proposal that did not result from a material breach of this Section 4.6, inform a Person that has made or, to the Knowledge of the Stockholder or its Representative (as applicable), is considering making an Acquisition Proposal of the restrictions of this Section 4.6 and of the Merger Agreement. For clarity, if such Stockholder is a venture capital or private equity investor, the term “Representative” (a) shall include any general partner of such Stockholder that is still affiliated with such Stockholder, but (b) shall exclude (i) any limited partner, (ii) any general partner that is no longer affiliated with such Stockholder, and (iii) any employees or other Representatives, in each case of clauses (i) to (iii), who do not have actual knowledge of the Contemplated Transactions. Each Stockholder acknowledges and agrees that, for purposes of determining whether a breach of this Section 4.6 has occurred, the actions of such Stockholder’s directors and Representatives acting in their authorized capacities on behalf of such Stockholder shall be deemed to be the actions of such Stockholder, and such Stockholder shall be responsible for any breach of this Section 4.6 by its directors and Representatives acting in their authorized capacities on behalf of such Stockholder.

Section 4.7 Notices of Certain Events. Each Stockholder shall notify Parent of any development occurring after the date hereof that causes, or that would reasonably be expected to cause, any breach of any of the representations and warranties of such Stockholder set forth in Article II.

The word “will” shall be construed to have the same meaning and effect as the word “shall.” Whenever used in this Agreement, any noun or pronoun will be deemed to include the plural as well as the singular and to cover all genders. Any reference to any Person shall be construed to include such Person’s successors and assigns. This Agreement will be construed without regard to any presumption or rule requiring construction or interpretation against the party drafting or causing any instrument to be drafted. The parties hereto have participated jointly in the negotiation and drafting of this Agreement and, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as jointly drafted by the parties hereto and no presumption of burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of this Agreement.

Section 5.14 Further Assurances. Each Stockholder will execute and deliver, or cause to be executed and delivered, all further documents and instruments and use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws and regulations, to comply with its obligations under this Agreement.

Section 5.15 Capacity as Stockholder. Each Stockholder signs this Agreement solely in such Stockholder’s capacity as a stockholder of the Company, and not, if applicable, in such Stockholder’s capacity as a director, officer or employee of the Company. Nothing herein shall in any way restrict a director or officer of the Company in the taking of any actions (or failure to act) in his or her capacity as a director or officer of the Company, or in the exercise of his or her fiduciary duties as a director or officer of the Company, or prevent or be construed to create any obligation on the part of any director or officer of the Company from taking any action in his or her capacity as such director or officer, and no action taken in any such capacity as an officer or director of the Company shall be deemed to constitute a breach of this Agreement, provided, that, for the avoidance of doubt, nothing herein shall be understood to relieve any party to the Merger Agreement of any obligation under, or of any liability for breach of any provision of, the Merger Agreement.

Section 5.16 Representations and Warranties. The representations and warranties contained in this Agreement and in any certificate or other writing delivered pursuant hereto shall not survive the Effective Time or the valid termination of this Agreement in accordance with Section 5.2.

Section 5.17 No Agreement Until Executed. This Agreement shall not be effective unless and until (a) the Merger Agreement is executed by all parties thereto and (b) this Agreement is executed by all parties hereto.

Section 5.18 Stockholder Obligation Several and Not Joint. The obligations of each Stockholder hereunder shall be several and not joint, and no Stockholder shall be liable for any breach of the terms of this Agreement by any other Stockholder. Further, Parent and Purchaser agree that no Stockholder will be liable for claims, losses, damages, liabilities or other obligations of, or incurred by, the Company resulting from the Company’s breach of the Merger Agreement except to the extent that breach of such Stockholder’s obligations hereunder was also involved in such breach by the Company.

Section 5.19 Exclusion for Certain Company Stock Option Exercises. Notwithstanding anything to the contrary herein, Subject Shares surrendered to the Company in respect of payment of the exercise price upon exercise of Company Stock Options or for the withholding due upon such exercise shall not be Subject Shares subject to this Agreement, and this Agreement does not impose any restriction on such Transfer.
