			Dear Jean Paul,
		

		
			 
		

		
			I am glad a new agreement can be concluded.
		

		
			 
		

		
			Hereby our joint agreement concerning:
		

		
			The premature termination date of 2020 is eliminated for the contracts of the tower from the contracts.
		

		
			All penalty clauses will also be eliminated from these contracts.
		

		
			Galapagos waives its right of first refusal on the 5th floor of the tower.
		

		
			Galapagos leases the 7th floor from 07/01/2018, end date 12/31/2021.
		

		
			Galapagos leases the 6th floor proportionally from 01/01/2019, end date 12/31/2021.
		

		
			Galapagos leases 866m2 on the 1st floor in R&D1 (ex-labcorps) from 07/15/2018, end date 12/31/2021.
		

		
			Rent from 08/15/2018.*
		

		
			Galapagos has a right of first refusal on the other 1035m2 on the 1st floor in R&D1 (ex-labcorps) and may take this in lease in a phased manner.
		

		
			The new addenda will no longer include penalty clauses.
		

		
			The new end date for all contracts in the tower, including that of labcorps, is 12/31/2021.
		

		
			 
		

		
			*              Rent for space 1/L of lot 1 is €95/m2/year
		

		
			The restoration of the space 1/L will be performed by Intervest by 07/05/2018 (removal of existing walls, delivery open space, installation of new carpet, painting of walls, optimization of technical facilities and installation of sky lights. If Galapagos would like private interior works (partition walls, data cabling, ....), this work may be performed by Intervest in accordance with the Turn Key Solutions principle (whereby a coordination fee of 10% is charged).
		

		
			 
		

		
			Could you please prepare a contract proposal/addendum to include this agreement?
		

		
			With regard to +7, I will try to forward the contract so that this work can be started this week.
		

		
			 
		

		
			Thank you in advance.

			2.2        The leased areas are not guaranteed with regard to surface area in more or less, which constitutes an advantage of disadvantage of the Lessee.
		

		
			2.3        The Leased Object is leased in “as is” condition as known by the Lessee, with the understanding however that the Lessor commits to make the changes as described in article 6. The Lessee declares to have viewed and inspected the Leased Object.
		

		
			2.4        An inspection report will be prepared at the expenses of the Lessee by experts agency Thomas Collin, after the performance of the Lessor of the work outlined in article 6. The fee of the expert agency will be borne by the Lessee.
		

		
			3           Term
		

		
			3.1        The Leased Object 1: The Lessee is permitted to take the Leased Object 1 in to lease in a phased manner (per approx. 433m2). The two parts will be taken into use, at the discretion of the Lessee, either separately or together from a start date to be determined by the Lessee and no later than on 01/01/2019, with end date 12/31/2021.
		

		
			The Lessee will have the right to cancel Leased Object 1 on 06/30/2021, by registered letter with a notice period of six months. From 06/30/2021, the Leased Object 1 can be terminated on a monthly basis, by registered letter with a notice period of at least one month.
		

		
			The Lessee will inform the Lessor by registered letter if it would like to use the Leased Object 1 before 01/01/2019, in whole or in part. The Lessee must thereby take into account a timing of one and a half months in order for the Lessor to perform the work as described in article 6. After the starting location description was prepared, which will be scheduled as soon as possible after the receipt of the aforementioned registered letter of the Lessee, the Lessor will grant the Lessee access to the respective part of the Leased Object 1, in order to give the Lessee the opportunity to ready the respective part of Leased Object 1 by the predefined date of use. If the Lessee does not communicate an early start date, the lease of the Leased Object 1 will start on 01/01/2019.

			A completion by 08/22/2018 of the work to be performed by the Lessor as described in article 6 of the current addendum, is guaranteed by the Lessor on the condition that the current addendum is signed and submitted no later than on 06/20/2018. If this is not the case, this timing can no longer be guaranteed. If the Leased Object 2 is not ready for use by 08/22/2018, taking into account the above, the Lessee will receive a discount on the rents of the Leased Object 2 which discount will be calculated pro rata temporis in function of the number days of unavailability starting on 08/22/2018.
		

		
			Taxes and fees will be owed from the start of the use of the Leased Object 2.
		

		
			The rents for the Leased Object 2 are only owed from 08/22/2018.

			Or in total €215,295/year or €53,823.75/quarter, taking into account however (pro rata temporis) the start date for the lease of (all or part of) the Leased Object 1 and with the fact that the rent for the Leased Object 2 is not owed until 08/15/2018.
		

		
			4.2        The annual indexation of the rent will take place on each anniversary of the agreement, with base index May 2018.

			meet the conditions as described in the Base Lease Agreement.
		

		
			6           Modifications
		

		
			6.1        Leased Object 1:
		

		
			The Lessor commits to perform the following work at its own expense, as soon as possible after the signing of the current agreement and no later than by 01/01/2019:
		

		
			            Painting of permanent walls, where necessary, with repair of small damages
		

		
			            Cleaning of floors (wood) and installation of new floor covering (carpet) as is installed today
		

		
			            General clean up
		

		
			6.2        Leased Object 2:
		

		
			The Lessor commits to perform the following work at its own expense, as soon as possible after the signing of the current agreement and no later than by 08/22/2018:
		

		
			            Removal existing furnishings
		

		
			            Installation new T4 carpet tiles
		

		
			            Painting of permanent walls
		

		
			            Update of technical facilities (open space)
		

		
			            Installation of sky lights
		

		
			            General clean up
		

		
			7           Right of first refusal
		

		
			The Lessor hereby grants to the Lessee a right of first refusal for the office space on the same floor as the Leased Object 2, being the first floor of the building Intercity Business Park lot 1. This means that if the Lessor has a potential lessee for this office space, the Lessor will give preference to the Lessee to lease this office space under the same conditions (including rent) and for the same areas as the potential lessee. This implies that if the Lessee exercises the right of first refusal, it must at least lease the same space as the potential lessee. The end date of the term which must be concluded by the Lessee for the lease of the additional office space on the same floor as the Leased Object 2, after the exercise of the right of first refusal as further described below, the end date may not exceed 12/31/2021.
		

		
			The Parties expressly agree that, if after the exercise by the Lessee of the right of first refusal, part of the first floor of the building Intercity Business Park lot 1 remains unoccupied, the Lessee will retain the right of first refusal, as described above, for the remaining unoccupied area.
		

		
			For this purpose:
		

		
			     the Lessor will inform the Lessee by registered letter of the conditions against which a potential lessee is willing to lease the office space;
		

		
			     the Lessee will have the option during 10 calendar days (the “Option period”), counted from the receipt of the abovementioned registered letter, to lease the respective area under the same conditions (taking into account, with regard to the term, with the end date of 12/31/2021) and for the same areas;
		

		
			     the Lessee will be able to exercise this option within the Option period by informing the Lessor of the intention to lease the office space;
		

		
			     if the Lessee exercises the option, Parties will consult in good faith in order to determine the lease of the additional spaces under the same conditions with regard to the rent, the

			term (which may not exceed the end date of 12/31/2021) and surface area as offered by the potential lessee;
		

		
			     if the Lessee did not exercise the option within the Option period, the Lessor is permitted to lease the respective space to the potential lessee.
		

		
			If the Lessee exercises its right to, after exercise by the Lessee of the right of first refusal, additionally lease the remaining unoccupied space and, if so desired, in a phased manner, Parties will consult in good faith in order to contractually record the lease of this part. Thereby Parties will take into account the existing contractual agreements which apply between them at that time, specifically with regard to the Leased Object 2.
		

		
			8           General provision
		

		
			8.1        For the remainder all provisions of the aforementioned lease agreements of 06/30/1999 and 02/21/2001 and all addenda, will remain integrally in effect, and will also apply to the current agreement, and this insofar as not deviated from in this current addendum.
		

		
			8.2        The Lessor will have this addendum registered, whereby the registration fees are for the account of the Lessee.
		

		
			8.3        The registration fee is 0.20% and is calculated on the combined amount of the rent and the common costs for the entire term of this agreement. Pro fisco, these common costs that are imposed under this addendum, are estimated at 5% of the additional rent.
