For the purposes of this
Contract "Deferred Interest Rate" means a fixed interest rate of 6% per annum.

The Borrower shall pay all
accrued Deferred Interest in arrears on the Maturity Date of the relevant Tranche (or earlier on any prepayment or acceleration
of all or part of that Tranche).

Deferred Interest shall be
calculated in respect of each annual period following the Disbursement Date of each Tranche (other than the COVID-19 Tranche) on
the basis of Article 5.01.

		3.03	Interest on overdue sums

Without prejudice to Article
10 and by way of exception to Article 3.01, if the Borrower fails to pay any amount payable by it under this Contract on its due
date, interest shall accrue (subject to mandatory provisions of the applicable laws) on any overdue amount payable under the terms
of this Contract from the due date to the date of actual payment at an annual rate equal to:

		(i)	for overdue sums relating to Tranches (other than the COVID-19 Tranche), the applicable Floating
Rate plus [***]% ([***] basis points);

		(ii)	for overdue sums relating to the COVID-19 Tranche, the higher of (a) the PIK Interest Rate plus
2% (200 basis points) or (b) EURIBOR plus [***]% ([***] basis points); or

		(iii)	for overdue sums other than under (i) or (ii) above, EURIBOR plus 2% (200 basis points),

and shall be payable in accordance
with the demand of the Bank. For the purpose of determining EURIBOR in relation to this Article 3.03, the relevant periods within
the meaning of Schedule B shall be successive periods of one month commencing on the due date.

 

    	24  

    	 

    

 

 

If the overdue sum is in
a currency other than the currency of the Loan, the following rate per annum shall apply, namely the relevant interbank rate that
is generally retained by the Bank for transactions in that currency plus [***]% ([***] basis points), calculated in accordance
with the market practice for such rate.

		3.04	Market Disruption Event

In relation to a specific
Tranche, if at any time (i) from the issuance by the Bank of the Disbursement Notice in respect of such Tranche, and (ii) until
the date falling thirty (30) calendar days prior to the Scheduled Disbursement Date, a Market Disruption Event occurs, the Bank
may notify to the Borrower that this clause has come into effect. In such case, the rate of interest applicable to such Notified
Tranche until the Maturity Date of such Notified Tranche shall be the percentage rate per annum which is the sum of:

		·	the Cash Pay Margin and

		·	the rate (expressed as a percentage rate per annum) which is determined by the Bank to be the all-inclusive
cost to the Bank for the funding of the relevant Tranche based upon the then applicable internally generated Bank reference rate
or an alternative rate determination method reasonably determined by the Bank. The Borrower shall have the right to refuse in writing
such disbursement within the deadline specified in the notification and shall bear charges incurred as a result, if any, in which
case the Bank shall not effect the disbursement and the corresponding Credit shall remain available for disbursement under Article
1.02B. If the Borrower does not refuse the disbursement in time, the parties agree that the disbursement and the conditions thereof
shall be fully binding for both parties.

		3.05	PPI

		3.05A	In addition to the interest payable pursuant to Articles 3.01 and 3.02 above, provided either the
PPI Tranche or the COVID-19 Tranche is drawn, the Borrower shall pay PPI according to this Article 3.05.

		3.05B	Upon any repayment or prepayment of any part of the PPI Tranche becoming due (a "PPI Tranche
Due Payment") (whether or not it is paid and to avoid doubt whether as a result of the occurrence of the PPI Tranche's Maturity
Date, or following acceleration, or as a result of voluntary or mandatory prepayment, or otherwise), the Borrower shall pay the
Bank the relevant PPI within 30 days of the Bank's written demand, provided that such demand is delivered by the Bank to the Borrower
no later than the first anniversary of the PPI Tranche's Maturity Date.

		3.05C	Upon any repayment or prepayment of any part of the COVID-19 Tranche becoming due (a "COVID-19
Tranche Due Payment") (whether or not it is paid and to avoid doubt whether as a result of the occurrence of the COVID-19
Tranche's Maturity Date, or following acceleration, or as a result of voluntary or mandatory prepayment, or otherwise), the Borrower
shall pay the Bank the relevant PPI within 30 days of the Bank's written demand, provided that such demand is delivered by the
Bank to the Borrower no later than the first anniversary of the COVID-19 Tranche's Maturity Date.

		3.05D	For the avoidance of doubt the Bank has the right to demand the relevant PPI in relation to any
PPI Tranche Due Payment and any COVID-19 Tranche Due Payment at any time up to (and including) the first anniversary of the PPI
Tranche's Maturity Date or the COVID-19 Tranche's Maturity Date (as applicable).

		3.05E	The Borrower and the Bank hereby agree that the calculations illustrated as examples of the amount
of PPI to be paid by the Borrower under Schedule F (Performance Participation Interest Example) fairly represent the intention
of the parties.

		3.06	Payment in kind (PIK) interest

In relation to the COVID-19
Tranche, interest shall accrue daily on the outstanding balance of the COVID-19 Tranche at the PIK Interest Rate and shall be capitalised
on each Payment Date and added to the outstanding principal amount of the relevant Loan. All such accrued interest shall, after
being so capitalised, be treated as part of the principal amount of the relevant Loan, shall bear all interest in accordance with
this Article 3.06 and shall be payable on the Maturity Date of the COVID-19 Tranche, or, where the COVID-19 Tranche is voluntarily
prepaid or compulsorily prepaid on the relevant prepayment date (or, to avoid doubt, on such date as the COVID-19 Tranche becomes
due and payable as a result of an acceleration).

If the Borrower accepts the
Prepayment Notice no later than by the Acceptance Deadline, it shall effect the prepayment. In any other case, the Borrower may

member of the Group) or any Guarantor voluntarily prepays (for the avoidance of doubt, prepayment shall include a repurchase, redemption
or cancellation where applicable) a part or the whole of any Non-EIB Financing and:

revolving credit facility);

		·	such prepayment is not made out of the proceeds of a loan or other indebtedness having a term at

the Bank may, by notice to
the Borrower, cancel the undisbursed portion of the Credit and demand prepayment of the Loan. The proportion of the Loan that the
Bank may require to be prepaid shall be the same as the proportion that the prepaid amount of the Non-EIB Financing bears to the
aggregate outstanding amount of all Non-EIB Financing.

inform the Bank if a Change-of-Law Event has occurred or is reasonably likely to occur. In such case, or if the Bank has reasonable
cause to believe that a Change-of-Law Event has occurred or is about to occur, the Bank may request that the Borrower consult with
it. Such consultation shall take place within 30 (thirty) days from the date of the Bank's request. If, after the lapse of 30 (thirty)
days from the date of such request for consultation the Bank is of the opinion that the effects of the Change-of-Law Event cannot
be mitigated to its satisfaction, the Bank may by notice to the Borrower, cancel the undisbursed portion of the Credit and demand
prepayment of the Loan, together with accrued interest and all other amounts accrued or outstanding under any Finance Document.

or a Guarantor's ability to perform its obligations under this Contract or any guarantee or security provided in respect of this
Contract.

If it becomes unlawful in
any applicable jurisdiction for the Bank to perform any of its obligations as contemplated in any Finance Document or to fund or
maintain the Loan, the Bank shall promptly notify the Borrower and may immediately (i) suspend or cancel the undisbursed portion
of the Credit and/or (ii) demand prepayment of the Loan, together with accrued interest and all other amounts accrued or outstanding

A repaid or prepaid amount
may not be reborrowed. This Article 4 shall not prejudice Article 10.
