 6 Multiple Borrowers 
 Multiple borrowers shall be liable as joint debtors for the
liabilities arising from this contract. 
 If the Sparkasse is paid off by a borrower, it shall not verify whether this borrower is entitled to
claims on collateral it no longer requires. It shall basically return such collateral to the collateral provider, as long as the paying borrower does not prove that the collateral provider’s approval is on hand for issue to it. 

7 Requirements regarding disclosure and information 
 For the entire duration of this loan, the Borrower shall grant the Sparkasse or an agency it designates, at any time and at least once annually, the right to examine the current business relationships, to
hand over related relevant documents (e.g., balance sheets/annual financial statement, income tax reports and declarations, statements of assets and liabilities, and so on), to provide any requested information, and to enable inspection of its
business. The Sparkasse is required, based on legal and supervisory guidelines, to have the Borrower’s business relationships disclosed to it.

documents are stored on data carriers, the Borrower shall be required to make these legible within a suitable period of time.

as those persons who, for technical, organizational, or legal reasons, are to be included in verifying the market value or executing the transfer (e.g., rating agencies, auditors, tax consultants, attorneys, or notaries). The Borrower shall release
the Sparkasse to that extent from the banking secrecy requirement.

of information, if such a requirement does not already exist due to legal or profession-related/professionally accepted provisions. The confidentiality requirement comprises maintaining secrecy regarding all customer-related data and values and to
use the information only in the scope necessary to execute the described measures. The Sparkasse shall also require third parties to settle corresponding confidentiality agreements with additional recipients prior to the transfer of rights stemming
from the contract and the dissemination of information to them.
