	 	(g)	Profit Margin Royalty Adjustments. In the event that gross profits associated with the sale of the Licensed Product in a country of the Licensed Territory falls below [***] percent ([***]%) at the time of the
first commercial sale of the Licensed Product or in any subsequent calendar quarter, then the Parties shall discuss in good faith a reduction of royalty burden to Pieris in such country. In the event that gross profits associated with the sale of
the Licensed Product in a country of the Licensed Territory rises above [***] percent ([***]%) at the time of first commercial sale of the Licensed Product or in any subsequent calendar quarter, then the Parties shall discuss in good faith an
increase in the royalty payable to Pieris for sales of the Licensed Product in such country. In the event that royalties are reduced or increased under this section and gross profits are subsequently restored to above [***]% or below [***]% within a
calendar quarter, as applicable, then the royalty rate shall be restored to the level set forth in this agreement. For avoidance of doubt, in case gross profits after such restoration fall again below [***]% or raise above [***]% in any calendar
quarter, the previously agreed reduction or increase shall again become effective. In no event, however, shall royalties to Pieris fall below [***] percent ([***]%) of Net Sales. Gross profit shall be further defined in the Definitive Agreements but
shall essentially be calculated as Net Sales minus the royalties set forth above and minus cost of goods sold (to be defined in the Definitive Agreement) for the Licensed Product. 


 

	 	(h)	Biosimilar Royalty Reductions. The royalty applicable to the Net Sales of a Licensed Product in the Licensed Territory will be reduced by up to: (i) [***] percent ([***]%) if there is one (1) biosimilar
product (to be defined in the Definitive Agreements) for the Licensed Product being commercially sold in the Licensed Territory at the time of such sale; (ii) [***] percent ([***]%) if there are [***] ([***]) biosimilar products for the Licensed
Product being sold in the Licensed Territory at the time of such sale; or (iii) [***] percent ([***]%) if there are [***] ([***]) or more biosimilar products for the Licensed Product being sold in the Licensed Territory at the time of such sale, in
each case, being marketed by a Third Party in the Licensed Territory and where the sales (on a units basis) of at least [***] such generic product exceed [***] ([***]%) of the sales of the Licensed Product (on a units basis) (during the applicable
calendar quarter). The actual percentage reduction adjustment (as above) will be negotiated in good faith by the Parties to reflect the impact of the biosimilar product on ASKA, taking into consideration (i) increased marketing costs incurred
by ASKA in marketing the Licensed Product, (ii) reduced Net Sales of the Licensed Product or reduced growth of total Net Sales of the Licensed Product and (iii) reduced market share of the Licensed Product, in each case, caused by the
entry of such biosimilar product in the Licensed Territory, and in any case not to exceed the applicable cap in reduction set forth above.
