Stephan To Bank: Comerica Bank-California 600 "B" Street, Suite 100 San Diego, California 92101 Attn: William A. Burzynski All agreements between the Borrowers and the Bank pertaining to the indebtedness described herein are expressly limited so that in no event whatsoever shall the amount of interest paid or agreed to be paid to the Bank exceed the highest rate of interest permissible under applicable law. If, from any circumstances whatsoever, fulfillment of any provision of this Agreement, the Loan Documents, the Notes or any other instrument securing the Notes or all or any part of the indebtedness secured thereby, at the time performance of such provision shall be due, shall involve exceeding the interest limitation validly prescribed by law which a court of competent jurisdiction may deem applicable thereto, then, the obligation to be fulfilled shall be reduced to an amount computed at the highest rate of interest permissible under such applicable law, and if, for any reason whatsoever, the Bank shall ever receive as interest an amount which would be deemed unlawful under such applicable law, such interest shall be automatically applied to the payment of the principal amount described herein or otherwise owed by the relevant Borrowers to Bank (whether or not then due and payable) and not to payment of interest. 12.5 This Agreement, the Loan Documents and the Notes shall be governed by, and construed and enforced in accordance with, California law. 12.6 Borrowers hereby indemnify, save and hold Bank and any of its past, present and future officers, directors, shareholders, employees, representatives and consultants harmless from any and all loss, damages, suits, penalties, costs, liabilities and expenses (including but not limited to reasonable investigation, environmental audit(s), and legal expenses) arising out of any claim, loss or damage of any property, injuries to or death of persons, contamination of or adverse affects on the environment, or any violation of any applicable Environmental Laws, caused by or in any way related to the real property owned by Borrowers, or due to any acts of Borrowers, its officers, directors, shareholders, employees, consultants and/or representatives. In no event shall the Borrowers be liable hereunder for any loss, damages, suits, penalties, costs, liabilities or expenses arising from any act of gross negligence or willful misconduct of Bank, or its agents or employees. 12.7 It is expressly understood and agreed that the indemnifications granted herein are intended to protect Bank, its past, present and future officers, directors, shareholders, employees, consultants and representatives from any claims that may arise by reason of the security interest, liens and/or mortgages granted to Bank, or under any other document or agreement given to secure repayment of any indebtedness from Borrowers, whether or not such claims arise before or after Bank has foreclosed upon and/or otherwise become the owner of any such property. All obligations of indemnity as provided hereunder shall be secured by the Loan Documents. 12.8 It is expressly agreed and understood that the provisions hereof shall and are intended to be continuing and shall survive the repayment of any indebtedness from Borrowers to the Bank. 12.9 Borrowers and the Bank acknowledge that the right to trial by jury is a constitutional one, but that it may be waived, and, after consulting with counsel of their choice, knowingly and voluntarily, and for their mutual benefit, waive any right to trial by jury in the event of litigation regarding the performance or enforcement of, or in any way related hereto.
