“(e) Right of First Refusal.

1.During the Term, before Lessor may convey, assign, or otherwise transfer its ownership interest in all or any portion of the Premises to a third party, Lessee shall have a right of first refusal to purchase the Premises on the material terms and conditions that Lessor is willing to sell the Premises to a third party following the procedures set forth in this Paragraph 30(e).

2.Prior to entering into a binding agreement to sell the Premises to a third party, Lessor shall deliver to Lessee written notice (the “Right of First Refusal Offer Notice”) of the material terms and conditions that Lessor has negotiated in good faith, and is willing to accept, from a third party, including the purchase price at which Lessor is willing to sell the Premises (such price, the “Right of First Refusal Purchase Price”). Upon Lessee’s receipt of a Right of First Refusal Offer Notice, Lessee shall have fifteen (15) calendar days to deliver written notice (a “Right of First Refusal Acceptance Notice”) to Lessor that it will purchase the Premises for the Right of First Refusal Purchase Price and on the terms and conditions set forth in the Right of First Refusal Offer Notice.

3.If Lessee timely delivers a Right of First Refusal Acceptance Notice electing to purchase the Premises on the terms and conditions set forth in the Right of First Refusal Offer Notice, then Lessor shall be bound to convey, assign, or otherwise transfer the Premises to Lessee promptly thereafter at the Right of First Refusal Purchase Price and on the terms and conditions set forth in the Right of First Refusal Offer Notice, and the parties shall proceed to consummate the sale of the Premises.

4.If Lessee (i) fails to timely deliver a Right of First Refusal Acceptance Notice, or (ii) elects not to purchase the Premises on the terms and conditions set forth in the Right of First Refusal Offer Notice, then Lessor shall be free for a period of one

hundred fifty (150) calendar days (such 150-calendar day period, “Lessor’s Sale Period”) to convey, assign, or otherwise transfer the Premises to a third party at a price not less than the Right of First Refusal Purchase Price and not on more favorable material terms and conditions than those stated in the Right of First Refusal Offer Notice. Any conveyance, assignment, or transfer of the Premises by Lessor to a third party shall be fully subject to the terms of this Lease and Lessor agrees to take all necessary steps to ensure the terms of this Lease shall be binding upon any new third party owner of the Premises.

5.If Lessor shall not have so conveyed, assigned, or transferred the Premises to a third party within Lessor’s Sale Period, then Lessor may not sell the Premises (or any portion thereof) to a third party without providing a new Right of First Refusal Offer Notice to Lessee and complying with the foregoing provisions of this Paragraph 30(e).

6.Lessee’s rights under this Paragraph 30(e) shall be at all times subordinate in all respects to all rights and remedies of JPMorgan Chase Bank, N.A. (the “Bank”) under the Bank’s deed of trust encumbering the Premises, such that Lessee’s rights under this Paragraph 30(e) shall not survive any foreclosure on the Premises by the Bank pursuant to its deed of trust, and shall not apply to any sale of the Premises by a receiver appointed by the Bank pursuant to its deed of trust.”

3.Lessor’s Access. Paragraph 32 of the Original Lease shall be amended to add the following as a new sentence thereto:

“In addition, Lessor and Lessor's agents shall have the right, at reasonable times, to enter the Premises for a period of up to fifteen (15) days, to remove Lessor’s papers and personal effects from the Premises, in each case, provided Lessor shall not thereby unreasonably interfere with Lessee’s business on the Premises.”

4.Miscellaneous.

a.Full Force and Effect. Except as expressly amended hereby, all of the representations, warranties, terms, covenants, conditions and other provisions of the Original Lease shall remain unchanged and shall continue to be, and shall remain, in full force and effect in accordance with their respective terms. The amendments set forth herein shall be limited precisely as provided for herein to the provisions expressly amended herein and shall not be deemed to be an amendment to, waiver of, consent to or modification of any other term or provision of the Original Lease.

b.Conflict. In the event of any conflict between the terms of this Second Amendment and the Original Lease, the terms of this Second Amendment shall

control and govern and the provisions of the Original Lease are to be construed in light of the intent of this Second Amendment.

c.Entire Agreement. This Second Amendment sets forth the entire agreement between the Parties regarding the matters set forth herein, superseding all prior agreements and understandings, written and oral, and may not be changed, modified or cancelled orally.

d.Governing Law. This Second Amendment shall be governed by and construed in accordance with the laws of the State of California, without regard to any conflicts of law provisions thereof.

e.Further Action. Each Party to this Second Amendment shall execute all instruments and documents and take such further action as may be reasonably required to effectuate the purpose of this Second Amendment.

h.Severability. The invalidity of any portion of this Second Amendment shall not have any effect on the balance thereof.

i.No Broker. Each of Lessee and Lessor represents to the other that it has not dealt with any brokers in connection with this Second Amendment and that no broker negotiated this Second Amendment or is entitled to any commission in connection herewith. Each Party agrees to indemnify, defend and hold the other harmless from and against all claims, demands, actions, liabilities, damages, costs and expenses (including, reasonable attorneys’ fees) arising from any claim for a fee or commission made by any broker claiming to have acted by or on behalf of the indemnifying Party in connection with this Second Amendment. The foregoing indemnity shall survive the expiration or termination of the Lease.

IN WITNESS WHEREOF, the Parties have caused this Second Amendment to be executed by their duly authorized officers or agents on the Second Amendment Effective Date.
