ACCESS: LANDLORD’S CHANGES

9.1. Access.

(A) Subject to the terms of this Lease, Tenant, during the Term, shall have access to the Premises at all times, twenty-four (24) hours per day, every day of the year.

(B) Subject to the terms of this Section 9.1(B), Landlord and Landlord’s designees may enter the Premises at reasonable times upon reasonable prior notice to Tenant (which notice may be given verbally to the person employed by Tenant with whom Landlord’s representative ordinarily discusses matters relating to the Premises) to (i) examine the Premises, (ii) show the Premises to prospective tenants during the last twelve (12) months of the Term, (iii) show the Premises to prospective purchasers or master lessees of Landlord’s interest in the Real Property, (iv) show the Premises to Mortgagees or Lessors (or prospective Mortgagees or Lessors), (v) gain access to Reserved Areas, or (vi) make repairs, alterations, improvements, additions or restorations that (I) Landlord is required to make pursuant to the terms of this Lease (including, without limitation, Landlord’s Work), or (II) are reasonably necessary in connection with the maintenance, repair, or operation of the Real Property (Landlord’s entry upon the Premises to perform such repairs, alterations, improvements, additions or restorations being referred to herein as a “Work Access”). Landlord shall not be required to give Tenant advance notice of the entry by Landlord or Landlord’s designees into the Premises as contemplated by this Section 9.1(B) to the extent necessary by reason of the occurrence of an emergency (with the understanding, however, that Landlord shall give Tenant notice of such emergency access as promptly as reasonably practicable thereafter). Landlord, in connection with a Work Access, shall have the right to bring into the Premises, and, to the extent required, store in the Premises in a reasonable manner for the duration of the Work Access, the materials and tools that Landlord reasonably requires to perform the applicable repair, alteration, improvement, addition or restoration. Landlord shall have no liability to Tenant for any loss sustained by Tenant by reason of Landlord’s entry upon the Premises; provided, however, that (w) nothing contained in this Section 9.1(B) diminishes Landlord’s obligation to repair the Premises (to the extent that the necessity for such repair derives from a Work Access) as provided in Section 8.1 hereof, and (x) subject to Section 14.3 hereof, Landlord shall remain liable to Tenant for personal injury or property damage that derives from Landlord’s negligence or wilful misconduct in connection with any such entry upon the Premises.

9.2. Landlord’s Obligation to Minimize Interference.

(A) Subject to Section 9.2(B) hereof, Landlord shall use commercially reasonable efforts to minimize interference with Tenant’s use of the Premises in connection with Landlord’s accessing the Premises as contemplated by Section 9.1 hereof.

(B) Subject to the provisions of this Section 9.2(B), Landlord shall have no obligation to employ contractors or labor at overtime or premium pay rates in connection with a Work Access as contemplated by this Article 8. If a Work Access (i) denies Tenant from having reasonable access to the Premises, (ii) threatens the health or safety of any occupant of the Premises, or (iii) materially interferes with Tenant’s ability to conduct its business in the Premises during Tenant’s ordinary business hours, then Landlord shall employ contractors or labor at overtime or premium pay rates to the extent reasonably necessary. Landlord, at Tenant’s request, shall also conduct a Work Access, to the extent reasonably practicable, using contractors or labor at overtime or premium pay rates, in which case Tenant shall pay to Landlord, as additional rent, an amount equal to the excess of (x) the Out-of-Pocket Costs that Landlord incurs in conducting such Work Access (using contractors or labor at overtime or premium pay rates), over (y) the Out-of-Pocket Costs that Landlord would have incurred in conducting such Work Access without using contractors at overtime or premium pay rates, within thirty (30) days after the date that Landlord gives to Tenant an invoice therefor together with reasonable supporting documentation for the charges set forth therein (it being understood that if more than one tenant requests that Landlord conduct such Work Access using contractors or labor at overtime or premium pay rates, then Landlord shall allocate such costs among such tenants equitably).

9.3. Reserved Areas.

The Premises shall not include (i) the demising walls of the Premises (except for the interior face thereof), (ii) the walls of the Premises that constitute the curtain wall for the Building (except for the interior face thereof), (iii) balconies, terraces and roofs that are adjacent to the Premises, and (iv) space that is used for Building Systems or other purposes associated with the operation, repair, management or maintenance of the Real Property, including, without limitation, shafts, stacks, stairways, chutes, pipes, conduits, ducts, fan rooms, mechanical rooms, plumbing facilities, and service closets (the areas described in clauses (iii) and (iv) above being collectively referred to herein as the “Reserved Areas”).

9.4. Ducts. Pipes and Conduits.

Landlord shall have the right to install, use and maintain ducts, cabling, pipes and conduits in and through the Premises, provided that (a) such ducts, cabling, pipes and conduits are concealed within or above partitioning columns, walls or ceilings, except that if such ducts, cabling, pipes or conduits are installed in areas that are utility areas (such as storage areas, mailrooms or mud rooms), then such ducts, cabling, pipes or conduits may also be installed on partitioning walls, columns or ceilings, (b) such ducts, cabling, pipes and conduits do not reduce the usable area of the Premises by more than a de minimis amount, and (c) Landlord installs such ducts, cabling, pipes and conduits in a manner that minimizes, to the extent reasonably practicable, any adverse effect on an Alteration theretofore performed in the Premises. If

34

Landlord requires access to the Premises to make the installations as contemplated by this Section 9.4, then Landlord shall perform such installations in accordance with the terms hereof that govern a Work Access.

9.5. Keys.

Tenant shall provide Landlord, from time to time, with the keys to the Premises (or with the appropriate means to access the Premises using Tenant’s electronic security systems).

9.6. Landlord’s Changes.

(A) Subject to Section 9.6(B) hereof, Tenant shall have the right to use, in common with the other occupants of the Building, the portions of the Building that Landlord dedicates from time to time as common area for the general use of the occupants of the Building.

(B) Landlord, from time to time, shall have the right to change the arrangement or location of the public portions of the Building, including, without limitation, lobbies, entrances, passageways, doors, corridors, stairs and toilets that in each case are not located in the Premises, provided any such change does not (a) unreasonably reduce or unreasonably interfere with Tenant’s access to the Building or the Premises, (b) reduce the floor area of the Premises (except to a de minimis extent), or (c) reduce to a material extent the level or quality of services that are available to Tenant on the Commencement Date.

(C) Landlord, from time to time, shall have the right to change, or reduce the number of, the passenger or freight elevators serving the Premises, provided that such change or reduction does not reduce to a material extent the passenger or freight elevator service standards that the passenger and freight elevators meet on the date hereof.

(D) Landlord, from time to time, shall have the right to change the name, number or designation by which the Building is commonly known.

(E)

(1) Landlord shall have the right, from time to time, to close, obstruct or darken the windows of the Premises temporarily to the extent required to comply with a Requirement or to perform repairs, maintenance, alterations, or improvements to the Building. Landlord shall have the right to close, obstruct or darken the windows of the Premises permanently to the extent required to comply with a Requirement that does not become applicable to the Building by virtue of Landlord’s performance of elective construction in the Building.

(2) If, at any time, the windows of the Premises are closed, obstructed or darkened temporarily, as aforesaid, then Landlord shall perform (or cause to be performed) such repairs, maintenance, alterations or improvements, or shall comply with the applicable Requirement (or cause such Requirement to be complied with), in each case with reasonable diligence, and otherwise take such action as may be reasonably necessary to minimize the period during which such windows are temporarily closed, obstructed or darkened (it being understood,

35

however, that subject to Section 8.4 hereof, Landlord shall not be required to perform such repairs, maintenance, alterations or improvements using contractors or labor at overtime or premium pay rates).
