Tenant will have thirty (30) business days within which to elect to lease any Contiguous Space at terms and conditions no different from those contained in such offer.

In the event that Tenant elects not to lease any Contiguous Space, Landlord may lease such space to a third party on the same terms and conditions as those contained in the offer to Tenant. If Landlord desires to lease the Contiguous Space on terms and/or conditions different from those contained in the offer, Landlord will first offer the Contiguous Space on such different terms and/or conditions to Tenant and Tenant will then have fifteen (15) business days within which to elect to lease such Contiguous Space.

25.1 Procedure for Offer of Right of First Refusal. Landlord shall notify Tenant in writing (the “First Offer Notice”) from time to time whenever the First Offer Space or any

8

portion thereof will become available for lease to third parties and a third party makes an offer for the space, the Landlord shall provide Tenant a true, correct, and complete copy of any offer received from any third party. Pursuant to such First Offer Notice, Landlord shall offer to lease to Tenant the then available First Offer Space. The First Offer Notice shall describe the space so offered to Tenant and shall set forth the “First Offer Rent,” as that term is defined in Section 25.3 below, and the other economic and material non-economic terms upon which Landlord is willing to lease such space to Tenant (collectively, the “Fundamental Terms”), which Fundamental Terms shall pertain to the following categories: (i) the usable and rentable square footage of the First Offer Space (subject to the remeasurement provisions of Section 3 of this First Amendment, above), (ii) the delivery condition, including any required Landlord work and any Landlord warranties regarding the condition of the First Offer Space, (iii) rights to expand, options to purchase, rights of first refusal, and other material space-encumbering rights, (iv) the length of term, including the lease commencement date and options or other rights to extend the lease term or to terminate the lease, (v) base rent, including escalations thereto, expressed as a dollar amount per rentable square foot, (vi) monetary concessions (e.g., free rent, improvement allowances), (vii) operating expense and tax protections, including any rent stop or base year protections, (viii) parking rights, (ix) parking charges, and (x) the date by which the First Offer Space will be delivered to the tenant and the period of time, if any, granted to the tenant for the construction or build-out period of the First Offer Space prior to the obligation to pay rent. The term of Tenant’s lease of any First Offer Space shall terminate thirty (30) days after Tenant’s receipt of the First Offer.

26.2 Procedure for Acceptance. If Tenant wishes to exercise Tenant’s right of first offer with respect to the space described in the First Offer Notice, then within twenty (20) business days of receipt of the First Offer Notice to Tenant (the “Exercise Period”), Tenant shall deliver notice to Landlord of Tenant’s intention to exercise its right of first offer with respect to the space so described in the First Offer Notice on the Fundamental Terms contained in such notice. If Tenant does not so notify Landlord prior to the expiration of the Exercise Period, then Landlord shall be free to lease the space described in the First Offer Notice to anyone to whom Landlord desires on the same Fundamental Terms of the First Offer Notice to the Tenant; provided, however, that if the Fundamental Terms differ from the First Offer Notice to the Tenant, then before entering into such third party lease, Landlord shall notify Tenant of such different Fundamental Terms and Tenant shall have the right to lease the First Offer Space (as the same may have been reconfigured and/or resized) upon such different Fundamental Terms by delivering written notice thereof to Landlord within ten (10) business days after Tenant’s receipt of Landlord’s Revised Offer Notice.

In the event Landlord fails to lease such First Offer Space to a third party, Landlord shall again be obligated to deliver a First Offer Notice to Tenant with regard to the subject First Offer Space, and Tenant shall again have the right to lease such First Offer Space in accordance with this Section.

Landlord shall only deliver such a First Offer Notice to the extent Landlord has a bona-fide prospective tenant (i.e., a prospective tenant with which Landlord is conducting active negotiations)

9

26.3 First Offer Space Rent. The Rent payable by Tenant for the First Offer Space (the “First Offer Rent”) shall be as set forth in the First Offer Notice.

26.4 Construction In First Offer Space. Tenant shall take the First Offer Space in its “as is” condition, and the construction of improvements in the First Offer Space by Tenant shall comply with the Tenant Work Letter of this First Amendment, subject to the delivery condition and any improvement allowance component of the Fundamental Terms.

25.5 The lease term for any space leased by Tenant under the exercise of its First Right of Refusal will be coterminous with the Initial Term or the Renewal Option periods, as applicable. The Rental Abatement, Tenant Improvements and other applicable terms and conditions will be adjusted on a straight line, pro-rata basis to allow for differences in the length of the term.

27. Building Security. Landlord, as an Operating Expense of the Building, will provide twenty-four (24) hour on-site Building Security, equipment, personnel, procedures and systems. The Office Lease will contain an exhibit, acceptable to Tenant, setting forth building standard security specifications, procedures and systems. Tenant will be permitted to install its own additional Security System for its Premises.

28. Add to Transfers in Office Lease: Notwithstanding anything to the contrary in Article 14 of the Office Lease, Tenant will have the right to Assign or Sublease to, or from, any other tenant in the Building. Landlord will not impose any restrictions on the terms and conditions of such Assignment and Subleasing rights (such as minimum rent or further sub-subletting and/or assigning). Tenant’s Renewal Option & Option Space rights are not personal to Tenant and are fully transferable. Tenant’s vacating of its Premises will not be grounds for default under the proposed lease. Neither the use by, nor the Subletting to, any subsidiary or affiliate of Tenant of all or a portion of the Premises will be deemed an Assignment or Sublease under the lease and therefore Landlord’s consent will not be required.

29. Right of Recapture. Landlord will not have the right of recapture per Article 14 of the Office Lease

30. Non Disturbance Agreement: Landlord agrees to provide Tenant with a commercially reasonable subordination, nondisturbance and attornment agreement (the “Nondisturbance Agreement”) in favor of Tenant from any ground lessors, mortgage holders or lien holders (collectively, the “Current Lender”) of Landlord in existence as of the date of this Lease. In addition, Landlord agrees to provide Tenant with a Nondisturbance Agreement from any ground lessors, mortgage holders or lien holders (collectively, the “Future Lender”) of Landlord who later come into existence at any time prior to the expiration of the Lease Term. Current Lender and Future Lender may be collectively referred to herein as “Lender.” Tenant subordinates this Lease and its other interests, if any, in the Project to any lien upon Landlord’s interests in all or any portion of the Project which secures obligations of Landlord to the Future Lender. Future Lender and any purchaser at a foreclosure agrees that, notwithstanding such subordination, Future Lender shall, in the event of a foreclosure or deed in lieu, (i) recognize this Lease and the Tenant hereunder, (ii) assume and perform all of Landlord’s obligations set forth in this Lease accruing after the date of the foreclosure, and (iii) be subject to all uncured defaults of Landlord and all defenses whenever accruing and all rights and remedies of Tenant, except that Future Lender shall not be liable for any

10

defaults occurring prior to the date of the foreclosure or deed in lieu except to the extent such defaults are continuing thereafter. Furthermore, Tenant’s rights and interests with respect to the Premises and the Project shall not be impaired or disturbed by foreclosure or other enforcement of such lien except as expressly permitted under this Lease. Tenant agrees to attorn to any person who succeeds to Landlord’s interests through a foreclosure of such lien or transfer in lieu thereof.

IN WITNESS WHEREOF, this Fifth Amendment has been executed by the parties as of the date first referenced above.
