Check Verification. CSG’s Check Verification routes Automated Clearing House ("ACH") transactions to CSG’s approved third party Check Verification Provider ("CVP"). Check Verification also receives responses from CVP and provides appropriate dispositions to CSG’s respective payment applications. For responses to other payment applications, Customer will be responsible for integration and implementation of its front-end applications utilizing CSG’s standard XML protocol for the service.

Customer acknowledges and agrees that the provision of Check Verification services by CSG is contingent upon the following:

Customer certifies that it has a legitimate business need for the information provided by CSG and its third party suppliers (“Suppliers”) related to checks and ACH transactions payable to Customer.

Customer further represents, warrants, and certifies that it will: (i) use the response information solely in accordance with the federal Fair Credit Reporting Act (“FCRA”) and all other applicable federal, state, and local laws, rules and regulations; and (ii) use response information solely for a permissible purpose under section 604(a) of the FCRA, 15 U.S.C. § 1681b(a), and for no other purpose. CSG and its Suppliers reserve the right to decline to provide response information to Customer if, in CSG and its Suppliers’ sole opinion, it/they believe that such information will be used for a purpose other than a permissible purpose under Section 604(a) of the FCRA, 15 U.S.C. §1681b(a), or in violation of the terms of this Amendment.

Customer acknowledges that it has received and read the notice information prepared by the Federal Trade Commission that is located at http://www.ftc.gov/os/2004/11/041119factaapph.pdf describing obligations under law when using customer information. Customer acknowledges that verification services will apply to transactions originating solely within the United States and in U.S. currency.

Customer agrees that CSG and its Suppliers verification information will not be used for employment purposes, for the extension of credit, for insurance purposes or for any purpose which is prohibited by the Fair Credit Reporting Act (Public Law 91-508), or any other law presently governing such information supplied by CSG and its Suppliers or any law which subsequently shall govern said information. Customer further agrees that the information furnished by CSG and its Suppliers will be used only for the exclusive use of the Customer and will not be made available to any third parties.

CSG and its Suppliers do not guarantee the accuracy or completeness of the information supplied to Customer in connection with the verification services. Customer agrees that there will be no payment to Customer by CSG or its Suppliers for any loss from check transactions processed through the verification service. Customer assumes all risk that checks accepted by it may be dishonored. Customer shall indemnify and hold CSG and its Suppliers harmless against any and all claims, actions, losses, and expenses, including attorney’s fees and court costs, relating to any disputes or controversies with Customer's clients, customers or check writers related to or arising out of the verification services provided by CSG and its Suppliers under the terms of this Amendment, except to the extent such claims, actions, losses, and expenses arise from CSG’s gross negligence or willful misconduct. Customer also hereby agrees to indemnify CSG and its Suppliers, or any of their respective employees from any liabilities arising out of Customer’s use of any information obtained through the check verification process in violation of the FCRA, any other applicable law, rule or regulation. Under no circumstances shall CSG or its Suppliers be liable for special, consequential or exemplary damages including, without limitation, lost profits or revenues.

In the event any provision of this Exhibit C-28 is held to be unenforceable or invalid by a court of competent jurisdiction, the validity and enforceability of the enforceable portion of any such provision and/or the remaining provisions of this Exhibit C-28 shall not be affected thereby; provided that with respect to any material provision declared non-enforceable or invalid, the parties shall negotiate in good faith to define a legally enforceable provision which most closely approximates the original intent of the provision declared unenforceable or invalid.

CSG AND ITS SUPPLIERS MAKE, AND CUSTOMER RECEIVES, NO WARRANTY, EXPRESSED OR IMPLIED, AND THERE ARE EXPRESSLY EXCLUDED ALL WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. NEITHER PARTY SHALL HAVE LIABILITY WITH RESPECT TO ITS OBLIGATIONS UNDER THIS EXHIBIT C-28 FOR CONSEQUENTIAL, SPECIAL, DIRECT, EXEMPLARY, OR INCIDENTAL DAMAGES TO THE OTHER PARTY, THEIR SUPPLIERS, MERCHANTS OR THIRD PARTIES DEALING WITH THE OTHER PARTY EVEN IF THE OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

In no event will any terms, conditions or fees set forth in this Exhibit C-28 apply to Customer’s performance under the Agreement other than with respect to CSG’s provision and Customer’s use of CSG’s Check Verification Services. Except as provided in this Exhibit C-28, all other terms of the Agreement which are not in conflict with this Exhibit C-28 for the use of CSG’s Check Verification shall be given full force and effect. In the event of a conflict between the terms of the Agreement and the terms of this Exhibit C-28, the terms of this Exhibit C-28 shall control and take precedence with respect to CSG’s provision and Customer’s use of CSG’s Check Verification.
