Failure by an Indemnified Party to so notify Parent shall not relieve Parent from the obligation to indemnify the Indemnified Party pursuant to this Section 5.06 unless Parent is actually prejudiced as a result of such failure. Parent shall be entitled to assume the defense of any such Proceeding with counsel reasonably satisfactory to the Indemnified Party. Without limiting Parent’s obligation to indemnify, reimburse and hold harmless the Indemnified Parties pursuant to Section 5.06(a), upon assumption by Parent of the defense of any such Proceeding, the applicable Indemnified Party shall have the right to participate in such Proceeding and to retain its own counsel at Parent’s expense; provided, however, that Parent shall not, in connection with any one such Proceeding or separate but substantially similar Proceedings arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Parties, except to the extent that local counsel, in addition to its regular counsel, is required in order to effectively defend against such Proceeding.

Nothing in this Agreement is intended to, shall be construed to or shall release, waive, limit or impair any rights to indemnification, contribution, advancement of expenses or insurance to which Thomas Bevilacqua is entitled under the the Company’s or the Surviving Corporation’s certificate of incorporation and bylaws (or such documents of any successor to the business of either Person), any agreement Thomas Bevilacqua has with the

Company or the Surviving Corporation or any predecessor or successor to either such Person or its business or the Merger Agreement.

(d) If Parent or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any one Person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of Parent shall assume the obligations set forth in this Section 5.06

(e) The rights of each Indemnified Party under this Section 5.06 shall be in addition to any rights such Person may have under the charter or bylaws of the Company or any of its subsidiaries under Delaware law or any other applicable laws or under any agreement of any Indemnified Party with the Company or any of its subsidiaries. These rights shall survive consummation of any acquisition of the Company by Parent and are intended to benefit, and shall be enforceable by, each Indemnified Party.

Section 6.05 Interpretation. The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any

provision of this Agreement. When a reference is made in this Agreement to Articles, Sections or Schedules, such reference shall be to an Article or Section of or Schedule to this Agreement unless otherwise indicated. Headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” References to “the date hereof” shall mean the date of this Agreement. As used herein, “business day” means any day other than a Saturday, a Sunday or a day on which banks in New York, New York are authorized by law or executive order to be closed. All references to “dollars” or “$” in this Agreement are to United States dollars. This Agreement shall not be interpreted or construed to require any Person to take any action, or fail to take any action, if to do so would violate any Applicable Law. References to any statute or regulation refer to such statute or regulation as amended, modified, supplemented or replaced from time to time (and, in the case of statutes, include any rules and regulations promulgated under the statute) and references to any section of any statute or regulation include any successor to such section.

Section 6.06 Counterparts. This Agreement may be executed in two or more counterparts (including by facsimile or other electronic means) all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

Section 6.07 Entire Agreement. This Agreement and, to the extent referenced herein, the Merger Agreement, together with the several agreements and other documents and instruments referred to herein or therein or attached hereto or thereto, constitute the entire agreement among the parties and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof and thereof.

Section 6.08 Governing Law; Consent To Jurisdiction; Waiver Of Jury Trial.

(a) This Agreement shall be governed and construed in accordance with the laws of the State of Delaware, without regard to any applicable conflicts of law.

(b) Each party agrees that it will bring any action or proceeding in respect of any claim arising out of or related to this Agreement or the transactions contemplated hereby exclusively in any federal or state court located in the State of Delaware (the “Chosen Courts”), and, solely in connection with claims arising under this Agreement or the transactions that are the subject of this Agreement, (i) irrevocably submits to the exclusive jurisdiction of the Chosen Courts, (ii) waives any objection to laying venue in any such action or proceeding in the Chosen Courts, (iii) waives any objection that the Chosen Courts are an inconvenient forum or do not have jurisdiction over any party and (iv) agrees that service of process upon such party in any such action or proceeding will be effective if notice is given in accordance with Section 6.04.

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH

SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT: (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6.08(c).

Section 6.09 Amendment; Waiver. This Agreement may not be amended except by an instrument in writing signed by Parent and the Stockholder. Each party may waive any right of such party hereunder by an instrument in writing signed by such party and delivered to the other parties, but such waiver shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

Section 6.10 Remedies. The parties hereto agree that irreparable damage would occur if any provision of this Agreement were not performed in accordance with its specific terms or were otherwise breached. Accordingly, the parties shall be entitled to seek specific performance of the terms hereof, including an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof, in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereby further waives (a) any defense in any action for specific performance that a remedy at law would be adequate and (b) any requirement under any Law to post security or a bond as a prerequisite to obtaining equitable relief.

Section 6.11 Severability. Whenever possible, each provision or portion of any provision of this Agreement shall be interpreted in such manner as to be effective and valid under Applicable Law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any Applicable Law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or portion of any provision in such jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction such that the invalid, illegal or unenforceable provision or portion thereof shall be interpreted to be only so broad as is enforceable.

Section 6.12 Delivery by Facsimile or Electronic Transmission. This Agreement and any signed agreement or instrument entered into in connection with this Agreement, and any amendments or waivers hereto or thereto, to the extent signed and delivered by means of a facsimile machine or by e-mail delivery of a “.pdf” format data file, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect

as if it were the original signed version thereof delivered in person. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or e-mail delivery of a “.pdf” format data file to deliver a signature to this Agreement or any amendment hereto or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine or e-mail delivery of a “.pdf” format data file as a defense to the formation of a contract and each party hereto forever waives any such defense.

Section 6.13 Successors and Assigns; Third Party Beneficiaries. Other than to a transferee pursuant to a Permitted Transfer, neither this Agreement nor any of the rights, interests or obligations contained herein shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties. Any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and permitted assigns. Except as provided in Section 5.06, this Agreement (including the documents and instruments referred to herein) is not intended to, and does not, confer upon any person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein, other than the Company which shall be, and hereby is, an express third party beneficiary of this Agreement.

Section 6.14 Expenses. All costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense.
