If the commencement date is not the first day of a calendar month, or if the Sublease termination date is not the last day of a calendar month, a prorated monthly installment shall be paid at the then current rate for the fractional month during which the Sublease -2- commences and/or terminates.

If any action on the part of Sublessee or use of the Premises by Sublessee shall cause, directly of indirectly, any increase of Sublessor's insurance expense, said additional expense shall be paid by Sublessee to Sublessor upon written demand. No such payment by Sublessee shall limit Sublessor in the exercise of any other rights or remedies, or constitute a waiver of Sublessor's right to require Sublessee to discontinue such act or use. -3- 7.

The foregoing indemnification shall survive the expiration of the Term or earlier termination of this Sublease. B.

Sublessor acknowledges that it is not the intent of this Section to prohibit Sublessee from carrying on its operations or to unreasonably interfere with such operations. Sublessee may carry on its operations according to the custom of the industry so long as the use, presence and disposal of Hazardous Substance is strictly and properly monitored according to all applicable governmental requirements. The aforementioned disclosures shall be hand-delivered, sent via courier, or sent via overnight delivery and shall be addressed to: Director, Environmental Health and Safety, The Scripps Research Institute, 10550 North Torrey Pines Road, Mail Drop BCC-078, La Jolla, CA 92037, phone: (619) 784-8240. C. Notwithstanding the provisions of this Section, Sublessor shall have the right to terminate this Sublease in the event that (i) Sublessee uses the Premises for the generation, storage, use, treatment or disposal of Toxic Materials in a manner prohibited by applicable law and such use has a material adverse effect on Sublessor or the Premises; (ii) Sublessee has been required by any governmental authority to take remedial action in connection with Toxic Materials contaminating the Premises if the contamination resulted from Sublessee's action or use of the Premises and such remedial action has a material adverse effect on Sublessor or the Premises; or (iii) Sublessee is subject to an enforcement order issued by any governmental authority in connection with the use, disposal or storage of Toxic Materials on the Premises and such enforcement order has a material adverse effect on Sublessor or the Premises. Each of the foregoing events shall be deemed to be a material default by Sublessee under this Sublease. D. Upon the expiration or upon any early termination of this Sublease, Premises shall be returned by Sublessee to Sublessor in good operating condition and free of Toxic Materials. At that time, presuming there has been no release, discharge or emission of Toxic Materials on the Premises during Sublessee's occupancy thereof, Sublessee shall furnish to Sublessor, at Sublessee's sole cost, the results of appropriate environmental tests and studies as may be customary, reasonable, and in accordance with all applicable requirements of governmental entities and applicable environmental laws, so as to obtain -5- assurance that the Premises are free from any Toxic Materials or contamination in excess of legally permissible levels. If, however, a release, discharge or emission of Toxic Materials has occurred on the Premises during Sublessee's occupancy thereof, Sublessee shall furnish to Sublessor, at Sublessee's sole cost, a then-customary environmental audit or similar remediation plan for the Premises, plus such additional tests and studies as may be customary, reasonable or recommended by said audit, so as to obtain a then-customary and reasonable verification that the Premises are free from any Toxic Materials or contamination in excess of legally permissible levels. If said tests or studies indicate that there are any impermissible levels of Toxic Materials on the Premises, then, to the extent such impermissible levels of Toxic Materials were generated by Sublessee, Sublessee shall pay for all costs necessary to clean up and remedy said impermissible levels of Toxic Materials to the extent such levels of Toxic Materials are not permitted by applicable governmental laws or regulations. Sublessor shall cooperate in good faith with Sublessee to approve a remediation plan which mitigates the overall damages and costs. but if such remediation plan involves a delay in completing the remediation, then Sublessee shall agree to toll the statute of limitations for the duration of said delay applicable to any claim against Sublessee related to Sublessee's obligation to clean up Toxic Materials. Provided, however, Sublessee shall have no duty with respect to any such Toxic Materials which (i) were on the Premises prior to the effective date, or (ii) were placed on the Premises by means of spillage or seepage from a neighboring property, or (iii) were generated by Sublessor. E. Sublessee's obligations under this section and under Paragraph 47 of the Master Lease shall survive the termination of this Sublease. During any period of time employed by Sublessee after the termination of this Sublease to complete the removal from the Premises of any such Toxic Materials, Sublessee shall continue to pay the full Rent in accordance with this Sublease. (Provided, however, to the extent that some or all of the Premises continue to be used while the remediation work is being conducted, then said rental income or value of the portion of the Premises which are used shall be credited against the Rent otherwise payable by Sublessee for the same premises and time period.) 8. MISCELLANEOUS PROVISIONS A. Parking: Sublessor shall provide Sublessee approximately eighteen (18) parking spaces in the parking garage in accordance with Paragraph 40 of the Master Lease (Exhibit A hereto). B. Utility Usage: Sublessor and Sublessee intend to prorate the cost of utility usage including air conditioning, heating and electrical usage based on Sublessor being responsible for fifty- five and five-tenths percent (55.5%) of such charges and Sublessee being responsible for forty-four and five-tenths percent (44.5%) of such charges. Should either party use excessive utility -6- services, then such party will be responsible for the cost of the excess utility usage. C. Telecommunications Room: Sublessor, upon reasonable notice to Sublessee, will have access to the telecommunications room located in the Premises leased to Sublessee as outlined on the floor plan attached hereto as Exhibit B. D. Warm Room: The parties hereto understand and acknowledge that access to an incubation area or "warm room" is important to the scientific research conducted by both parties. Since the Premises contain a warm room to which both parties hereto desire access, Sublessee agrees that, until a replacement solution (in the form of additional warm room facilities) is identified, Sublessor shall have unrestricted, exclusive access to the warm room facilities contained within the leased Premises. In consideration for said access, Sublessor agrees to reduce the rent due to Sublessor from Sublessee by fifty percent (50%) during the time Sublessor has access to the warm room facilities within the leased Premises, until such time that a replacement solution is in operation. Sublessor further agrees to use its reasonable best efforts to make a replacement solution available. E. First Right to Negotiate: Sublessor will provide Sublessee with a first right to negotiate to lease the remaining space occupied by Sublessor if Sublessor vacates said space any time during the term of the Sublease. F. Storage Room: Sublessor and Sublessee agree to prorate the cost of the storage room which provides deionized water and other services, whereby Sublessee shall pay Sublessor a monthly charge of $175.00/month with annual CPI adjustments, pursuant to paragraph 49 of the Master Lease. 9. NOTICES All notices or demands of any kind required or desired to be given by Sublessor or Sublessee hereunder shall be in writing and shall be deemed delivered forty-eight (48) hours after depositing the notice or demand in the United States mail, certified or registered, postage prepaid, addressed to the Sublessor or Sublessee, respectively, at the addresses set forth after their signatures hereinbelow.
