4.6 Agreement with Respect to Bank Premises.
(a) Option to Purchase. Subject to Section 3.5, the Receiver hereby grants to the Assuming Bank an exclusive option for the period of ninety (90) days commencing the day after Bank Closing to purchase any or all owned Bank Premises. The Assuming Bank shall give written notice to the Receiver within the option period of its election to purchase or not to purchase any of the owned Bank Premises. Any purchase of such premises shall be effective as of the date of Bank Closing and such purchase shall be consummated as soon as practicable thereafter, and in no event later than the Settlement Date. If the Assuming Bank gives notice of its election not to purchase one or more of the owned Bank Premises within seven (7) days of Bank Closing, then, not withstanding any other provision of this Agreement to the contrary, the Assuming Bank shall not be liable for any of the costs or fees associated with appraisals for such Bank Premises.
(b) Option to Lease. The Receiver hereby grants to the Assuming Bank an exclusive option for the period of ninety (90) days commencing the day after Bank Closing to cause the Receiver to assign to the Assuming Bank any or all leases for leased Bank Premises, if any, which have been continuously occupied by the Assuming Bank from Bank Closing to the date it elects to accept an assignment of the leases with respect thereto to the extent such leases can be assigned; provided, that the exercise of this option with respect to any lease must be as to all premises or other property subject to the lease. If an assignment cannot be made of any such leases, the Receiver may, in its discretion, enter into subleases with the Assuming Bank containing the same terms and conditions provided under such existing leases for such leased Bank Premises or other property. The Assuming Bank shall give notice to the Receiver within the option period of its election to accept or not to accept an assignment of any or all leases (or enter into subleases or new leases in lieu thereof). The Assuming Bank agrees to assume all leases assigned (or enter into subleases or new leases in lieu thereof) pursuant to this Section 4.6.
(c) Facilitation. The Receiver agrees to facilitate the assumption, assignment or sublease of leases or the negotiation of new leases by the Assuming Bank; provided, that neither the Receiver nor the Corporation shall be obligated to engage in litigation, make payments to the Assuming Bank or to any third party in connection with facilitating any such assumption, assignment, sublease or negotiation or commit to any other obligations to third parties.
(d) Occupancy. The Assuming Bank shall give the Receiver fifteen (15) days' prior written notice of its intention to vacate prior to vacating any leased Bank Premises with respect to which the Assuming Bank has not exercised the option provided in Section 4.6(b). Any such notice shall be deemed to terminate the Assuming Bank's option with respect to such leased Bank Premises.
