(a) Company's Indemnity. The Company agrees to indemnify and hold harmless ValorInvest and its officers, directors, shareholders, agents, and employees, from and against, for and in respect of, and promptly shall reimburse them for, any and all claims, losses, costs, and expenses (including the cost of any investigation and reasonable attorneys' fees), damages, lawsuits, obligations, deficiencies, and liabilities (collectively "Losses") which arise or result from or are related to (b) the inaccuracy or breach of any representation or warranty made by the Company herein, (c) any breach or failure of the Company to perform any of its covenants or agreements set forth herein, or (d) any claim against ValorInvest arising out of or relating to events occurring prior to the date hereof. (b) ValorInvest's Indemnity. ValorInvest agrees to indemnify and hold harmless the Company and its officer, directors, shareholders, agents, and employees, from and against, for and in respect of, and shall promptly reimburse them for, any and all Losses which arise or result from or are related to (a) the inaccuracy or breach of any representation or warranty made by ValorInvest herein, or (b) any breach or failure of ValorInvest to perform any of its covenants or agreements set forth herein. (c) Indemnification Procedure. An indemnifying party shall not be liable under this Section 7 with respect to any claim made against an indemnified party unless such indemnifying party shall be notified in writing of the nature of the claim within a reasonable time after the assertion thereof, but failure so to notify such indemnifying party shall not relieve it from any liability which it may have otherwise than on account of this Section 8. If a claim is made against an indemnified party and it notifies the indemnifying party as herein provided, then the indemnifying party, subject to the provisions set forth herein, shall be entitled to participate at its own expense in the defense thereof or, if it so elects within a reasonable time after receipt of such notice, to assume the defense thereof, which defense shall be conducted by counsel chosen by it and reasonably satisfactory to the indemnified party defendant or defendants in any suit so brought. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses, and other charges of such counsel will be at the expense of such indemnified party unless (a) the employment of counsel by the indemnified party has been 14 15 authorized in writing by the indemnifying party, (b) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (c) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party will not have the right to direct the defense of such action on behalf of the indemnified party), or (d) the indemnifying party has not employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements, and other charges of counsel will be at the expense of the indemnifying party or parties. It is understood that the indemnifying party shall not, in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys for the indemnified parties. (d) Cumulative Remedies. All remedies provided herein shall be cumulative and shall not preclude the assertion by any party hereto of any other rights or the seeking of any other remedies against the other parties hereto. (e) Survival of Representations and Warranties. The representations, warranties, covenants, and agreements made by the parties in this Agreement, or in any certificate, agreement, or document furnished pursuant hereto, and the obligation to indemnify hereunder shall survive the date hereof and the consummation of the transactions contemplated hereby, notwithstanding any investigation made by or on behalf of any party; provided, however, (i) except as set forth in (ii) hereof, no action (other than an action for fraud) shall be brought by any party hereto against any other party hereto more than three (3) years after the date hereof, and (ii) with respect to an action for breach of the representations and warranties of Section 3(i) hereof (Taxes), no action shall be brought against the Company after the end of the statute of limitations for such actions. 9.
