INDEMNIFICATION 3.1 Indemnification. The Shareholder agrees to indemnify and hold the Buyer, the Company and their respective affiliates, officers, directors, agents and representatives (each, an "Indemnified Party") harmless against and in respect of (i) any and all claims, losses, liabilities, damages, deficiencies, costs and expenses (including reasonable attorneys' fees and expenses) to the extent based upon, arising out of or relating to the Assumed Liabilities; and (ii) any and all claims, losses, liabilities, damages, deficiencies, costs and expenses (including reasonable attorneys' fees and expenses) incurred by the Indemnified Party as a result of any breach by the Shareholder of any of its representations and warranties contained herein. 3.2 Claiming Procedure. Promptly after the assertion of any claim by a third party which may give rise to a claim for indemnification from the indemnitor (the "Indemnitor") under this Agreement, the Indemnified Party shall notify the Indemnitor in writing of such claim and advise the Indemnitor whether the Indemnified Party intends to contest such claim. In order to administer the claiming procedure and to facilitate the processing of any claims, the Buyer hereby entrusts to R.D. Gourley & Co. Certified Public Accountants, 501 S. First Avenue, Arcadia, CA 91006, all books and records of the Company who shall hold them as a fiduciary and make them available on reasonable notice to the Buyer and its authorized agents during regular business hours. The Indemnified Party shall permit the Indemnitor to contest and defend against such claim, at the Indemnitor's expense, if the Indemnitor has confirmed to the Indemnified Party in writing that it agrees that the Indemnified Party is entitled to indemnification hereunder in respect of such claim, unless the Indemnified Party believes that the conduct of its defense by the Indemnitor could be reasonably likely to prejudice such Indemnified Party due to the nature of the claims presented or by virtue of a conflict between the interests of such Indemnified Party and such Indemnitor or between such Indemnified Party and another Indemnified Party whose defense has been assumed by the Indemnitor. Notwithstanding a determination by the Indemnitor to contest such claim, the Indemnified Party shall have the right to be represented by its own counsel and accountants at its own expense except as set forth above. In any case, the Indemnified Party shall make available to the Indemnitor and its attorneys and accountants, at all reasonable times during normal business hours, all books, records, and other documents in its possession relating to such claim. The party contesting any such claim shall be furnished all reasonable assistance in connection therewith by the other party (with reimbursement of reasonable expenses by the Indemnitor). If the Indemnitor fails to undertake the defense of or to settle or pay any such third-party claim within 30 days after the Indemnified Party has given written notice to the Indemnitor advising the Indemnitor of such claim, or if the Indemnitor, after having given notice to the Indemnified Party that it intends to undertake the defense, fails forthwith to defend, settle or pay such claim, then the Indemnified Party may take any and all necessary action to dispose of such claim including, without limitation, the settlement or full payment thereof upon such terms as it shall deem appropriate, in its sole discretion. 7 3.3 Tax Gross-Up. In the event that a payment to the Indemnified Party by Indemnitor is treated by the Internal Revenue Service or any similar state and/or local taxing authorities as taxable income, with no or only partial offset in the form of a corresponding deduction for a claim to a third party, through no fault of the Indemnified Party, then Indemnitor shall pay to the Indemnified Party an amount equal to the taxes paid by the Indemnified Party related to the aforementioned taxable income computed at the highest statutory rate. 3.4 Survival of Representations and Warranties. The representations and warranties of the parties included herein or pursuant hereto shall survive the Closing. ARTICLE IV. CONDITIONS 4.1 Conditions to Obligations of the Buyer.
