agreement affecting space in the Building or elsewhere in the Property.
If Landlord shall consent to the proposed assignment or subletting, as the case may be, then, in such event, Tenant may thereafter sublease (the whole but not part of the Premises) or assign pursuant to Tenants notice, as given hereunder; provided, however, that if such assignment or sublease shall not be executed and delivered to Landlord within one hundred twenty (120) days after the date of Landlords consent, the consent shall be deemed null and void and the provisions of Section 5.6.1 shall be applicable.
5.6.4 Notwithstanding the foregoing provisions of Sections 5.6.2, 5.6.3 and 5.6.5, but subject to the provisions of Sections 5.6.1, 5.6.5 and 5.6.6, Tenant shall have the right without the prior consent of Landlord but upon notice to Landlord as set forth in Section 5.6.1 to assign this Lease or to sublet the Premises (in whole or in part) to any other entity (the Successor Entity) (i) which controls or is controlled by Tenant or Tenants parent corporation, or (ii) which is under common control with Tenant, or (iii) which purchases all or substantially all of the assets of Tenant, or (iv) which purchases all or substantially all of the stock of (or other membership interests in) Tenant or (v) which merges or combines with Tenant, provided that the entity to which this Lease is so assigned or which so sublets the Premises has a credit worthiness (e.g. assets on a pro forma basis using generally accepted accounting principles consistently applied and using the most recent financial statements) which is the same or better than the Tenant as of the date of this Lease (the foregoing transferees referred to, individually or collectively, as a Permitted Transferee). Except in cases of statutory merger, in which case the surviving entity in the merger shall be liable as the Tenant under this Lease, Tenant shall continue to remain fully liable under this Lease, on a joint and several basis with the Permitted Transferee. If any parent or subsidiary of Tenant to which this Lease is assigned or the Premises sublet (in whole or in part) shall cease to be such a parent or subsidiary, such cessation shall be considered an assignment or subletting requiring Landlords consent.
5.6.5 In the case of any assignment or subleasing as to which Landlord may consent (other than an assignment or subletting permitted under Section 5.6.4 above) such consent shall be upon the express and further condition, covenant and agreement, and Tenant hereby covenants and agrees that, in addition to the Annual Fixed Rent, Additional Rent and other charges to be paid pursuant to this Lease, fifty percent (50%) of the Assignment/Sublease Profits (hereinafter defined), if any, shall be paid to Landlord. The Assignment/Sublease Profits shall be the excess, if any, of (a) the Assignment/Sublease Net Revenues as hereinafter defined over (b) the Annual Fixed Rent and Additional Rent and other charges provided in this Lease (provided, however, that for the purpose of calculating the Assignment/Sublease Profits in the case of a sublease, appropriate proportions in the applicable Annual Fixed Rent, Additional Rent and other charges under this Lease shall be made based on the percentage of the Premises subleased and on the terms of the sublease). The Assignment/Sublease Net Revenues shall be the
