5. In Exhibit G to the Purchase Agreement, the second paragraph of Section 9.5.1 of the form of Lease is hereby revised in its entirety to read as follows:

“On or before the Initial Term Expiration Date (or upon an earlier termination), all movable furniture, furnishings, trade fixtures and equipment installed in the Premises which is not Tangible Personal Property and which is not remaining in the Data Center may be removed by Tenant (and for the avoidance of doubt, all non-movable fixtures, including, but not limited to, fume hoods and biosafety cabinets which are hard-ducted to the HVAC system, shall not be required to be removed by Tenant). Any damage or injury to the Premises or the Buildings caused by such removal shall be repaired by Tenant, at Tenant’s sole expense. If any property of Tenant (other than that to be used by Tenant during the Data Center Term) is not removed by Tenant as of the date Tenant vacates the Premises, the same shall become the property of Landlord (and Tenant shall, within thirty (30) days after Landlord’s request, execute and deliver

to Landlord a quitclaim bill of sale with respect to such property, substantially in the form of Exhibit H-1 attached to the PSA), at no additional cost to Landlord, and be surrendered with the Premises as a part thereof, and such property may be retained or disposed of, sold, used or stored as determined by Landlord.”

6. No Other Amendment. Except as expressly amended by this First Amendment, the PSA shall remain in full force and effect.

7. Counterparts. This First Amendment may be executed in counterparts, each of which shall be deemed to be an original and all of which shall constitute part of a single agreement.
