NOW, THEREFORE, Bank and Borrower, in consideration of the premises and the sum of One Dollar ($1.00) to each in hand paid by the other, receipt and sufficiency of which are hereby acknowledged by each, do hereby agree as follows:

Section 1. Modification. The Contract as it relates to the Note and the Loan and Security Agreement shall be, and the same is, modified in the manner set forth in Attachment 2.

Section 2. Effect of Modification. Nothing contained in this Modification Agreement shall in any way impair the security now held for the indebtedness evidenced by the Contract or the lien priority thereof, nor waive, annul, vary or affect any provision, condition, covenant and agreement contained in the Contract, nor affect or impair any rights, powers and remedies under the Contract, except as herein specifically modified to do any one or more of the foregoing. If any provision in this Modification Agreement shall be interpreted or applied by a court or other tribunal with personal and subject matter jurisdiction over the parties hereto and the Contract, as modified, so as to impair the security now held for the indebtedness or lien priority thereof, or do any one or more of any of the foregoing, such provision shall be ineffective to the extent it causes an impairment of such security or the lien priority thereof or causes any of such other consequences, or the application thereof shall be in a manner and to an extent which does not impair such security or the lien priority thereof, or result in the occurrence of any of the other consequences. This Modification Agreement does not extend the expiration dates or enlarge the terms of any property, physical damage, credit and any other insurance written in connection with or financed by said Contract.

Section 3. Financing Statements. Borrower irrevocably authorizes Bank to file such financing statements as may be necessary to protect, in Bank’s opinion, Bank’s security interests and liens and, to the extent Bank deems necessary or appropriate, to sign the name of Borrower with the same force and effect as if signed by Borrower and to make public in financing statements and other public filings such information regarding Borrower as Bank deems necessary or appropriate, including, without limitation, federal tax identification numbers, social security numbers and other identifying information.

Section 4. Credit Investigations; Bank’s Responsibilities. Bank is irrevocably authorized by Borrower to make and have made such credit investigations as it deems appropriate to evaluate Borrower’s credit, personal and financial standing and employment, and Borrower authorizes Bank to share with consumer reporting agencies and creditors its experiences with Borrower and other information in Bank’s possession relative to Borrower. Bank shall not have any obligation or responsibility to do any of the following: (1) protect and preserve any collateral and other security given or to be given in connection with the Contract, as herein modified, against the rights of third persons having an interest therein; (2) provide information to third persons relative to the Contract, as herein modified, Bank’s liens and security interests in any collateral and other security, or otherwise with respect to Borrower; and (3) subordinate its liens and security interests in any collateral and other security to the interests of any third persons or to enter into control agreements relative to such collateral and other security.

Section 5. Usury. Bank does not intend to and shall not reserve, charge and collect interest, fees and charges under the Contract, as herein modified, in excess of the maximum rates and amounts permitted by applicable law. If any interest, fees and charges are reserved, charged and collected in excess of the maximum rates and amounts, it shall be construed as a mutual mistake, appropriate adjustments shall be made by Bank and to the extent paid, the excess shall be returned to the person making such a payment.

Section 6. Documentary Stamps, etc. To the extent not prohibited by law and notwithstanding who is liable for payment of the taxes and fees, Borrower shall pay, on Bank’s demand, all intangible taxes, documentary stamp taxes, excise taxes and other similar taxes assessed, charged and required to be paid in connection with this Modification Agreement, and any future extension, renewal and modification of the Contract, or assessed, charged and required to be paid in connection with any of the loan documents which make up the Contract.
