Section 5.09 Governing Law. This Agreement, and all claims or causes of action (whether at Law, in contract or in tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance hereof, shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware.

Section 5.10 No Third-Party Beneficiaries. Each of the parties agrees that its respective representations, warranties, covenants and agreements set forth herein are solely for the benefit of the other parties hereto, in accordance with and subject to the terms of this Agreement, and, except as otherwise set forth herein, this Agreement is not intended to, and does not, confer upon any Person other than the parties hereto and their respective successors and permitted assigns any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein. The representations and warranties in this Agreement are the product of negotiations among the parties and are for the sole benefit of the parties.

Section 5.11 Counterparts; Effectiveness. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument, and shall become effective when one or more counterparts have been signed by each of the parties and delivered (by telecopy, electronic delivery or otherwise) to the other parties. Signatures to this Agreement transmitted by facsimile transmission, by electronic mail in “portable document format” (“.pdf”) form, or by any other electronic means intended to preserve the original graphic and pictorial appearance of a document, will have the same effect as physical delivery of the paper document bearing the original signature.

Section 5.12 Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction (a) shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement and (b) shall not, solely by virtue thereof, be invalid or unenforceable in any other jurisdiction. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, the parties shall negotiate in good faith to determine a suitable and equitable provision to be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision.

Section 5.13 No Agreement Until Executed. This Agreement shall not be effective unless and until (i) the Company Board of Directors has approved the Merger Agreement, (ii) the Merger Agreement is executed by all parties thereto and (iii) this Agreement is executed by all parties hereto.

Section 5.14 Headings. Headings of the Articles and Sections of this Agreement are for convenience of the parties only and shall be given no substantive or interpretive effect whatsoever.

Section 5.15 Interpretation. When a reference is made in this Agreement to an Article or Section, such reference shall be to an Article or Section of this Agreement unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof”, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement, unless the context otherwise requires. The word “since” when used in this Agreement in reference to a date shall be deemed to be inclusive of such date. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. References in this Agreement to specific laws or to specific provisions of laws shall include all rules and regulations promulgated thereunder, and any statute defined or referred to herein or in any agreement or instrument referred to herein shall mean such statute as from time to time amended, modified or supplemented, including by succession of comparable successor statutes. Each of the parties has participated in the drafting and negotiation of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if it is drafted by all the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of authorship of any of the provisions of this Agreement. Any agreement or instrument referred to herein or in any agreement or instrument that is referred to herein means such agreement or instrument as from time to time amended, modified or supplemented, including by waiver or consent and references to all attachments thereto and instruments incorporated therein. References to “$” shall mean United States dollars. Any reference to days means calendar days unless Business Days are expressly specified. References to “written” or “in writing” include in electronic form.

Section 5.16 Shareholder Obligations Several and Not Joint. The obligations of each Shareholder hereunder shall be several and not joint, and no Shareholder shall be liable for any breach of the terms of this Agreement by any other Shareholder.

Section 5.17 Shareholder Capacity. No person executing this Agreement who is or becomes during the term hereof a director or officer of the Company, nor any director, officer, employee or Affiliate of a Shareholder who is an officer or director of the Company, shall be deemed to make any agreement or understanding in this Agreement in such person’s capacity as a director or officer of the Company. Each Shareholder is entering into this Agreement solely in

such Shareholder’s capacity as the beneficial holder of Subject Shares and nothing herein shall be construed to prohibit, limit or otherwise affect any Shareholder or any director, officer, employee or Affiliate of a Shareholder who is an officer or director of the Company, from taking (or refraining from taking) any action in such person’s capacity as a director or officer of the Company or otherwise fulfilling the obligations of such office (including the performance of obligations required by the fiduciary obligations of such Shareholder or any director, officer, employee or Affiliate of such Shareholder acting in his or her capacity as an officer or director of the Company), in each case, in accordance with the terms of the Merger Agreement.

Section 5.18 Further Assurances. From time to time and without additional consideration, each of the parties hereto shall execute and deliver such additional instruments, and shall take such further actions, as may be reasonably necessary or advisable to effect the actions and consummate the transactions contemplated by this Agreement.
