6.2 UBS Fixed Advances

For terms up to and including 6 months, the principal and interest are billed once upon expiry.

For terms of greater than 6 months, billing with interest occurs quarterly at the end of each calendar quarter, and billing with capital and interest occurs upon expiry.

The base interest rate is governed by the Euro market conditions for the relevant term and currency, plus the margin of UBS.

The interest rate is determined two banking days before use or renewal for the relevant term and currency. The instructions for the start or renewal of the loan must be received by UBS no fewer than two banking days before utilization or renewal. If such instructions are not received, advance payments due shall not be extended, and capital and interest will be charged to the relevant current account.

6.3 UBS LIBOR Loan

The loan interest rate is made up of the LIBOR (London Interbank Offered Rate, base interest rate) of the relevant currency for the selected fixed interest period, plus the margin determined by UBS.

The Borrower shall inform UBS of the desired amount, currency, and fixed interest period before the desired payment date. The interest rate shall then set by UBS. UBS shall comply with the rules of the Intercontinental Exchange Benchmark Administration Ltd. (IBA) regarding the date of interest rate determination, payment, and final maturity. Details can be found on the IBA homepage (▇▇▇.▇▇▇▇▇▇.▇▇▇/▇▇▇.▇▇▇▇▇). However, if the day of interest rate determination falls on a Swiss bank holiday, the interest rate shall be determined on the preceding bank working day.

Observing a notice period of 10 calendar days before the interest rate is set, the Borrower may change the amount, currency, and fixed interest period or generally the form of use at the end of a fixed interest period. Without such a notification from the Borrower, the UBS LIBOR loan shall automatically continue with the previous amount, currency, and fixed interest period, but with the newly determined interest rate.

Billing with interest shall take place quarterly at the end of each calendar quarter. The interest shall be charged to the relevant current account.

6.4 Deposits / Letters of Credit

The fees are determined by UBS on a case-by-case basis and are based in particular on the type, amount, term, and complexity of the transaction as well as the creditworthiness of the Borrower.

UBS is entitled to adjust fees at any time during the term of the guarantees, observing a notice period of 90 calendar days. The Borrower shall be notified in writing by UBS of such an adjustment.

6.5 Interest Calculation

The interest calculation is based on the 365/360 standard practice, i.e. the effective number of days per month in a 360-day year.

For the avoidance of doubt, it is clarified that the base interest rate used in order to calculate the loan interest rate may never be less than zero.

10.2 Extraordinary Termination

The Borrower is entitled to terminate the credit agreement extraordinarily at any time, observing a notice period of 30 calendar days, and to repay the outstanding utilizations in whole or in part.

UBS is entitled to terminate the credit agreement at any time with immediate effect and to make all claims including accrued interest, fees, etc., regardless of the terms of the loans granted, due immediately and to demand them immediately, if:

2)	a restructuring obligation is imposed upon the Borrower or a group company by an official order (particularly in the field of environmental protection), which, in the judgment of UBS, could have a material impact on its financial performance.
3)	the ownership/control circumstances of the Borrower change to a significant extent, in the judgment of UBS.
4)	the Borrower or a group company changes its legal or economic structure, for example through liquidation, sale of a significant portion of the assets, change of corporate purpose or business activity, merger, or restructuring, if, in the judgment of UBS, the relevant event could have a material impact on its financial capacity.

11. Compensation in the Event of Extraordinary Termination

In the event of an extraordinary termination by the Borrower, compensation must be paid, which is calculated from the difference between the agreed interest rate and the interest rate achievable at the time of early repayment for an investment on the cash market or capital market with the corresponding remaining term until the end of the fixed interest rate commitment. If the interest rate is higher than the investment rate, this results in a difference to be borne by the Borrower; if it is below the investment rate, this results in a difference in favor of the Borrower.

In the event of an extraordinary termination by UBS, the Borrower must compensate UBS for all disadvantages and/or costs incurred by UBS as a result. In the case of utilizations with a fixed interest rate, this includes namely the difference between the agreed interest rate and the interest rate achievable at the time of early repayment for an investment on the cash market or capital market with the corresponding remaining term until the end of the fixed interest rate commitment. Additional compensation remains reserved.

2)	there are no circumstances that would entitle UBS to an extraordinary termination and there are no pending legal disputes that could have a materially detrimental effect on the Borrower or its assets.
3)	at the time the contract was concluded, there was no official ruling affecting the Borrower (specifically in the field of environmental protection) that has not been disclosed to UBS. The Borrower also confirms this fact with regard to the companies it controls.

17. Transferability of Credit and Waiver of Bank-Customer Confidentiality

UBS may offer its rights arising from the credit relationship, including any securities for which it is liable, such as promissory notes and/or other securities, to be transferred in whole or in part to third parties at home and abroad, or it may transfer them to third parties at home and abroad.

It may make the information and data relating to the credit relationship accessible to all third parties involved in the transfer, including any rating agencies, at any time and is released from bank-customer confidentiality in this regard. If such third parties are not subject to Swiss bank-customer confidentiality, a transfer shall only occur if these parties undertake to maintain secrecy.

Each acquirer is entitled to transfer the acquired claims and other rights if the next acquirer in turn undertakes to maintain secrecy.

A transfer of promissory notes and/or other securities liable for the credit relationship may only take place if, at the same time, the claims arising from the credit relationship are transferred in whole or in part, or it is otherwise ensured that the security provider may also raise any objections that exist against the respective claim holder against the purchaser of the promissory note and/or other securities, and the security provider may demand return of the promissory note and/or other securities liable for the credit relationship after all secured claims have been paid off in full.

UBS (as well as any acquirer following a transfer according to this provision) may transfer, together with the transferred rights, a limit obligation agreed in the credit relationship and/or other obligations arising from the loan relationship to the acquirer without further consent of the Borrower.

The party assuming these obligations must be either a company affiliated with UBS or a Swiss or foreign financial institution (bank, insurance company, etc.). To the extent that UBS transfers the obligation, it is itself released from it. In accordance with this provision, UBS may also transfer the entire loan relationship to such an acquirer (contract transfer). Any acquirer may transfer the entire credit relationship to any subsequent acquirer.

18. Waiver of Offsetting

The Borrower waives its right to repay its obligations by way of offsetting any claims it may have against UBS and/or any acquirer of the rights arising from this credit relationship, even if its offset claim against UBS or the acquirer is irrecoverable due to insolvency or excessive indebtedness.
