          (o) The Company has good labor relations, and the Company has no Knowledge of any facts indicating that (i) the consummation of the Merger or any of the other transactions contemplated by this Agreement will have a material adverse effect on the labor relations of the Company, or (ii) any of the employees of the Company intends to terminate his or her employment with the Company.

38.

that such representations and warranties relate to a specific date, in which case such representations and warranties shall be accurate on and as of such specific date, (without giving effect to any “Material Adverse Effect” or other materiality qualification or any similar qualification contained or incorporated directly or indirectly in such representation or warranty); (iii) any breach of any covenant or failure to perform any obligation of the Company set forth in this Agreement, the Disclosure Schedule or the Closing Certificate; (iv) the failure of the Company to comply with local, state or federal labor and employment laws, rules and regulations, including without limitation all laws, rules or regulations dealing with employee wages and hours, on or before the Closing; (v) any matter or correspondence described in Part 2.9 of the Disclosure Schedule or (vi) any Legal Proceeding relating to any breach or inaccuracy of the type referred to in clause “(i),” “(ii),” “(iii),” (iv) or “(iv)” above (including any Legal Proceeding commenced by any Indemnitee for the purpose of enforcing any of its rights under this Section 9).

          (b) With the exception of inaccuracies or breaches of representations, warranties and covenants involving intentional misrepresentation or fraud, the Parent shall be entitled to be indemnified solely from the Escrow Amount not yet released by Parent pursuant to Section 1.8 for any Damages actually incurred by an Indemnitee as set forth in Section 9.2(a).

          (c) Except in the case of intentional misrepresentation or fraud, and without limiting the effect of any other limitation contained in this Section 9, the indemnification provided for in this Section 9.2 shall not apply, and an Indemnitee shall not be entitled to exercise any indemnification rights under this Section 9.2, except to the extent that the aggregate amount of the Damages against which all Indemnitees would otherwise be entitled to be indemnified under this Section 9.2 exceeds $200,000. At such time as the cumulative amount of such Damages exceeds $200,000 in the aggregate, then the Indemnitees shall be entitled to be indemnified against and compensated and reimbursed for the cumulative amount of such Damages (and not merely the portion of such Damages exceeding $200,000).

          (d) In the case of intentional misrepresentation or fraud by the Company or any Company Stockholder, the following provisions shall apply:

               (i) the Indemnitees shall have recourse to the Escrow Amount with respect to any Damages to which an Indemnitee is entitled to be held harmless, indemnified, compensated or reimbursed pursuant to Section 9.2 and which arise from or as a result of, or are connected with, such intentional misrepresentation or fraud (irrespective of the Person who actually participated in or had knowledge of such intentional misrepresentation or fraud); and

               (ii) in addition to the rights and remedies referred to in clause “(i)” of this sentence, with respect to any Company Stockholder who participated in or had knowledge of such intentional misrepresentation or fraud, there shall be no limit on such Company Stockholder’s liability for such intentional misrepresentation or fraud.

          (e) Nothing in this Agreement shall limit any remedy an Indemnitee may have against any Person for intentional misrepresentation or fraud under applicable tort laws.

39.

     9.3 Defense of Third Party Claims. In the event of the assertion or commencement by any Person of any claim or Legal Proceeding (whether against Merger Sub, the Company, Parent or any other Person) with respect to which any of the Indemnitors may become obligated to hold harmless, indemnify, compensate or reimburse any Indemnitee pursuant to this Section 9, Parent shall have the right, at its election, to proceed with the defense of such claim or Legal Proceeding on its own. If Parent so proceeds with the defense of any such claim or Legal Proceeding:

          (a) all reasonable expenses relating to the defense of such claim or Legal Proceeding shall be borne and paid from the Escrow Amount;

          (b) each Indemnitor shall make available to Parent any documents and materials in his or its possession or control that may be necessary to the defense of such claim or Legal Proceeding; and

          (c) Parent shall have the right to settle, adjust or compromise such claim or Legal Proceeding with the consent of the Stockholders’ Agent; provided, however, that such consent shall not be unreasonably withheld or delayed.

Parent shall (i) give the Stockholders’ Agent notice of the commencement of any such claim or Legal Proceeding against Parent, Merger Sub or the Company promptly after Parent becomes aware of such claims or Legal Proceeding and (ii) use reasonable efforts to notify the Stockholders’ Agent of all material developments relating to such claims or Legal Proceeding; provided, however, that any failure on the part of Parent to so notify the Stockholders’ Agent shall not limit any of the obligations of the Indemnitors under this Section 9 (except to the extent such failure materially prejudices the defense of such Legal Proceeding). If Parent does not elect to proceed with the defense of any such claim or Legal Proceeding, the Stockholders’ Agent may proceed with the defense of such claim or Legal Proceeding with counsel reasonably satisfactory to the Parent; provided, however, that the Stockholders’ Agent (i) will use reasonable efforts to notify Parent of all material developments relating to such claim or Legal Proceeding and (ii) may not settle, adjust or compromise any such claim or Legal Proceeding without the prior written consent of Parent (which consent may not be unreasonably withheld or delayed).

     9.4 Exercise of Remedies by Indemnitees Other Than Parent. No Indemnitee (other than Parent or any successor thereto or assign thereof) shall be permitted to assert any indemnification claim or exercise any other remedy under this Agreement unless Parent (or any successor thereto or assign thereof) shall have consented to the assertion of such indemnification claim or the exercise of such other remedy.

SECTION 10. Miscellaneous Provisions

     10.1 Stockholders’ Agent. If this Agreement is duly adopted by the Company’s stockholders, the Company’s stockholders shall be deemed to have irrevocably appointed David Strohm as their agent for purposes of Section 9 and for purposes of acting on behalf of the Company’s stockholders pursuant to the indemnity and holdback terms of this Agreement (the “Stockholders’ Agent”).
