In addition to the defaults described in Section 13.A of the Original Lease, the following shall also constitute a material default and breach of the Lease by Tenant: a default by the tenant under the 2345 Lease, beyond any applicable cure period expressly set forth in the 2345 Lease, without the necessity for additional notice or cure under this Lease. Section 13.H, titled “Habitual Default” is hereby deleted.

15.Assignment or Sublease (Consent by Landlord). The following paragraph is hereby added to Section 17.A:

“Notwithstanding this Section 17.A above, but subject to this paragraph below, so long as Cavium, Inc., a Delaware corporation, is the Tenant under this Lease, Tenant shall have the right to permit the occupancy of the Building by the employees of any of Tenant’s customers or service providers, provided that (i) such individuals (individually a “Business Related Occupant”, and collectively the “Business Related Occupants”) shall not occupy a separately demised portion of the Building (other than open air cubicles), and no demising walls shall be constructed within the Building to separate any of the Business Related Occupants from other occupants of the Building; (ii) such occupancy is not in connection with any assignment or sublease; (iii) such occupancy is not a subterfuge by Tenant to avoid its obligations under this Lease or the restrictions on Transfers pursuant to this Section 18; (iv) no rent or other consideration shall be charged by Tenant with respect to such occupancy; (v) the Business Related Occupants do not occupy, in the aggregate at any given time, more than fifteen percent (15%) of the rentable square footage of the Building; (vi) such occupancy shall otherwise be subject to all of the terms and conditions of this Lease; (vii) Tenant shall be liable for violations by any of the Business Related Occupants of the terms and conditions of this Lease; and (viii) Tenant shall remain fully responsible and liable for the performance of all of the obligations of the Tenant under the Lease. In no event shall the Business Related Occupants have any rights under this Lease. A breach or violation of this Lease by a Business Related Occupant which is not cured within any cure period expressly granted by this Lease shall constitute an Event of Default by Tenant under this Lease. The failure of any Business Related Occupant to vacate the Premises prior to the expiration or termination of this Lease shall be deemed a holding over by Tenant without Landlord’s consent. If the right to occupy granted by Tenant to any of the Business Related Occupants is evidenced by a written agreement, Tenant shall deliver a copy of such agreement to Landlord prior to allowing such Business Related Occupant to occupy any portion of the Premises.”

16.Option To Extend. In addition to all other terms and conditions set forth in Section 18 of the Original Lease, in order for Tenant’s exercise of an Option under this Lease to be effective, the tenant under the 2345 Lease must concurrently exercise its corresponding option to extend the term of the 2345 Lease. Notwithstanding anything in the Lease to the contrary, (i) if the tenant under the 2345 Lease is in monetary or material non-monetary default under any of terms, covenants or conditions of the 2345 Lease, or (ii) if the tenant under the 2345 Lease does not have the financial ability to meet its obligations under the 2345 Lease, as reasonably determined by Landlord, either at the time such tenant exercises its corresponding option or at any time thereafter prior to the commencement date of the applicable Option Term, then Landlord shall have, in addition to all of Landlord’s other rights and remedies provided in this Lease, the right to terminate the Option upon notice to Tenant, in which event the Lease Term shall not be extended pursuant to Section 18.A of the Original Lease. Section 18.B of the Original Lease is hereby amended to read in its entirety as follows:

If Tenant exercises an Option, Landlord shall send Tenant a notice setting forth the Fair Market Rental for the Option Term within thirty (30) days following the date of exercise. If Tenant disputes Landlord’s determination of Fair Market Rental for the Option Term, Tenant shall, within thirty (30) days after delivery to Tenant of Landlord’s notice setting forth Fair Market Rental for the Option Term, send to Landlord a notice stating that Tenant either elects to terminate its exercise of the Option, in which event the Option shall lapse and this Lease shall terminate on the Expiration Date, or that Tenant disagrees with Landlord’s determination of Fair Market Rental for the Option Term and elects to resolve the disagreement as provided in Section 18.C below. If Tenant does not timely send Landlord a notice as provided in the previous sentence, Landlord’s determination of Fair Market Rental shall be used in computing the Base Monthly Rent payable by Tenant during the Option Term pursuant to Section 18.A above. If Tenant elects to resolve the disagreement as provided in Section 18.C below and such procedures are not concluded prior to the commencement date of the Option Term, Tenant shall pay to Landlord the Base Monthly Rent as determined by Landlord (taking into account the Fair Market Rental as determined by Landlord) in the manner provided above pending the resolution of such dispute. If the Base Monthly Rent as finally determined pursuant to Section 18.C is greater than Landlord’s determination, Tenant shall pay Landlord the difference between the amount paid by Tenant and the Base Monthly Rent as so determined in Section 18.C within thirty (30) days after such determination. If the Base Monthly Rent as finally determined in Section 18.C is less than Landlord’s determination, the difference between the amount paid by Tenant and the Base Monthly Rent as so determined in Section 18.C shall be credited against the next installments of Base Monthly Rent due from Tenant to Landlord hereunder.”

17.Brokers. Tenant represents it has not utilized or contacted a real estate broker or finder with respect to this Amendment other than Cornish and Carey Commercial Newmark Knight Frank (“Tenant’s Broker”) and Tenant agrees to indemnify, defend with counsel reasonably acceptable to Landlord and hold Landlord and the Landlord Related Parties harmless from and against all claims, liabilities, obligations, penalties, fines, actions, losses, damages, costs or expenses (including without limitation reasonable attorneys fees) asserted by any other broker or finder claiming through Tenant. Landlord shall pay Tenant’s Broker a leasing commission in connection with this Amendment pursuant to a separate written agreement between Landlord and Tenant’s Broker.

19.Subordination. In the second (2^nd) to last sentence of Section 19.T of the Original Lease “non-distburbance” is revised to read “non-disturbance”. Landlord shall use its best efforts to obtain, not later than forty five (45) days after the Amendment Effective Date, from the Holder of the ground lease and deed of trust encumbering the Premises as of the Amendment Effective Date, a recognition and nondisturbance agreement (which may also provide for subordination as provided in Section 19.T of the Original Lease) which (i) provides that the Lease shall not be terminated so long as Tenant is not in default under the Lease beyond applicable notice and cure periods, and (ii) so long as the Lease remains in full force and effect, recognizes all of Tenant’s rights under the Lease and requires such Holder to be bound by Landlord’s obligations under the Lease to the extent such obligations accrue after the termination of the underlying ground lease (as to the Holder under a ground lease) or during the period of the deed of trust beneficiary’s fee ownership of the Premises (as to a Holder under the deed of trust), subject however to commercially reasonable exclusions (such as, without limitation, Landlord’s obligation relating to the Work Allowance), and contains other commercially reasonable provisions requested by such Holder.

20.Effect of Amendment. Except as otherwise revised by this Amendment, all terms and conditions of the Original Lease shall remain unchanged and in full force and effect. To the extent of any conflict between the terms of this Amendment and the terms of the Original Lease, the terms of this Amendment shall control. This Amendment may be executed in counterparts, each of which shall be deemed an original, and together shall constitute one and the same document.
