8.                                      No Default. Tenant represents, warrants and covenants that, to the best of Tenant’s knowledge, Landlord and Tenant are not in default of any of their respective obligations under the Lease and no event has occurred that, with the passage of time or the giving of notice (or both) would constitute a default by either Landlord or Tenant thereunder. Landlord represents, warrants and covenants that, to the best of Landlord’s knowledge, Landlord and Tenant are not in default of any of their respective obligations under the Lease and no event has occurred that, with the passage of time or the giving of notice (or both) would constitute a default by either Landlord or Tenant thereunder.

2.                                      Tenant Improvements. All Tenant Improvements shall be performed by Landlord’s contractor, at Tenant’s sole cost and expense and in substantial accordance with the Approved Plans (as defined below), the Amended Lease and this Work Letter. Landlord shall deliver to Tenant periodic invoices for the work completed in connection with this Work Letter. Tenant shall pay any invoice within thirty (30) days after receipt. If Tenant fails to pay, or is late in paying, any sum due to Landlord under this Exhibit C, then Landlord shall have all of the rights and remedies set forth in the Amended Lease for nonpayment of Rent (including, but not limited to, the right to interest and the right to assess a late charge), and for purposes of any litigation instituted with regard to such amounts the same shall be considered Rent. All material and equipment furnished by Landlord or its contractors as the Tenant Improvements shall be new or of the same or better quality than the materials in the existing Premises and the Tenant Improvements shall be constructed in a first-class, workmanlike manner and in compliance with all Applicable Laws.

2.1.                            Work Plans. Landlord shall prepare and submit to Tenant for approval schematics covering the Tenant Improvements prepared in conformity with the applicable provisions of this Work Letter (the “Draft Schematic Plans”). The Draft Schematic Plans shall contain sufficient information and detail to accurately describe the proposed design to Tenant. Tenant shall notify Landlord in writing within five (5) business days after receipt of the Draft Schematic Plans whether Tenant approves or objects to the Draft Schematic Plans and of the manner, if any, in which the Draft Schematic Plans are unacceptable. Tenant’s failure to respond within such five (5)-business day period shall be deemed approval by Tenant. If Tenant reasonably objects to the Draft Schematic Plans, then Landlord shall revise the Draft Schematic Plans and cause Tenant’s objections to be remedied in the revised Draft Schematic Plans. Within five (5) business days following submission of Tenant’s objection, Landlord shall then resubmit the revised Draft Schematic Plans to Tenant for approval, such approval not to be unreasonably withheld, conditioned or delayed. Tenant’s approval of or objection to revised Draft Schematic Plans and Landlord’s correction of the same shall be in accordance with this Section 2.1 until Tenant has approved the Draft Schematic Plans in writing or been deemed to have approved them.

Such Construction Plans shall be approved or disapproved by Tenant within five (5) business days after delivery to Tenant. Tenant’s failure to respond within such five (5)-business day period shall be deemed approval by Tenant. If the

C-2

Construction Plans are disapproved by Tenant, then Tenant shall notify Landlord in writing of its reasonable objections to such Construction Plans, and the parties shall confer and negotiate in good faith to reach agreement on the Construction Plans. Promptly after the Construction Plans are approved by Landlord and Tenant, two (2) copies of such Construction Plans shall be initialed and dated by Landlord and Tenant, and Landlord shall promptly submit such Construction Plans to all appropriate Governmental Authorities for approval. The Construction Plans so approved, and all change orders specifically permitted by this Work Letter, are referred to herein as the “Approved Plans.” Promptly following the approval of the Approved Plans, Landlord shall cause the Preliminary Cost Estimate to be updated and submitted to Tenant for approval (“Updated Estimate”), which approval shall not be unreasonably withheld.

Notwithstanding any provision to the contrary in this Work Letter or the Lease, if the nature of a Change requires revisions to the Approved Plans or otherwise increases the costs of the Tenant Improvements, then the requesting party shall be solely responsible for the cost and expense of such revisions or increased costs, except for any Change required to comply with any Applicable Law or change in Applicable Law, the cost for which Tenant shall be responsible. Change Requests shall be signed by the requesting party’s Authorized Representative.

(b)                                      Approval of Changes. All Change Requests shall be subject to the other party’s prior written approval, which approval shall not be unreasonably withheld, conditioned or delayed. The non-requesting party shall have five (5) business days after receipt of a Change Request to notify the requesting party in writing of the non-requesting party’s decision either to approve or object to the Change Request. The non-requesting party’s failure to respond within such five (5) business day period shall be deemed approval by the non-requesting party.

3.                                      Requests for Consent. Except as otherwise provided in this Work Letter, (i) Tenant shall respond to all requests for consents, approvals or directions made by Landlord pursuant to this Work Letter within five (5) business days following Tenant’s receipt of such request, and (ii) Tenant’s failure to respond within such five (5) business day period shall be deemed approval by Tenant.

Pico,

Thank you for the opportunity to provide budgetary pricing for the Apoptos Expansion project at the Road to the Cure Building.

Our scope includes the building of a new full height demising wall, new interior partition wall and new hardlid in room 222. The lighting switching will be separated in the Lab area and lighting circuits will be separated and new switching will added in the divided Room 222. New lighting will be provided in the hardlid and a standalone HVAC spit system will be used to cool the new equipment room, we have used the equipment list provided by Apoptos to size the HVAC equipment correctly. The existing corridor door in Room 222 will be in filled and the door will be relocated to the new wall within the room. The existing grid in the Lab area and the area outside the existing Cold Box will remain and will be tied into the new walls. The new walls will be finished to match existing conditions and new 4” rubber cover base will be installed on all new walls. No other work is to be done to the Existing Lab Benches or Overhead Service Carriers.

Please feel free to contact me with any questions about this proposal.

Thank You,
