WHEREAS,
the Parties desire to enter into this Amendment to amend certain terms of the Development Agreement, as set forth herein.

 

NOW,
THEREFORE, in exchange for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the
Parties agree as follows:

 

1.             DEFINITIONS.
  Capitalized terms herein used which are not herein defined shall have the respective meanings ascribed to them in the Development

Regarding Economic Viability.

 

	 	(a)	If at any time commencing with the quarter ending March 31, 2023, the market conditions in the Territory are such that total Net Profits (excluding the deduction for reimbursement of legal expenses) reach a level that is equal to or less than five percent (5%) of Scilex’s (and its Affiliates’) Net Sales of the Products and such conditions persist for a period of four (4) or more consecutive quarters, or

written notice to the other Party, and if Scilex shall terminate the Agreement, Scilex shall discontinue sales of the Product after all

such lidocaine tape products for certain territories in the world (the “Development Agreement”); and

 

Whereas,

terms of the Development Agreement, as set forth herein.

 

Now,
Therefore, in exchange for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the
Parties agree as follows:

 

1.              Definitions.

2.              Economic

and replaced with the following:

 

“15.6     Termination
Regarding Economic Viability. If at any time during the Term, market conditions in the Territory
are such that

 

		(a)	total Net Profits (excluding the deduction for reimbursement of legal expenses) reach a level that is equal to or less than five percent
