Lessee shall pay to Lessor as Rent, on or before the first day of each calendar month during the Lease Term, subject to adjustment and reconciliation as provided below, the sum of Nine Thousand Six Hundred Twelve Dollars($9,612), said sum representing Lessee's estimated monthly payment of Lessee's percentage share of CAC and includes a fixed monthly sum of Fourteen Hundred Seven Dollars ($1,407.00) which represents the long term capital reserve for replacement of existing HVAC units, parking lot, roof and painting of building exterior ("Capital Reserves").

Within 120 days of the end of the calendar year and the end of the Lease Term, Lessor shall provide Lessee a statement of actual CAC incurred including Capital Reserves for the preceding year or other applicable period in the case of a termination year. If such statement shows that Lessee has paid less than its actual percentage, then Lessee shall on demand pay to Lessor the amount of such deficiency.

Lessor reserves the right to revise any estimate of CAC if the actual or projected CAC show an increase or decrease in excess of 10% from an earlier estimate for the same period.

Such costs include, but are not limited to, processing and accounting charges, and late charges, which may be imposed on Lessor according to the terms of any mortgage or trust deed covering the Premises. Accordingly, if any installment of base monthly rent or monthly estimate of CAC is not received by Lessor or Lessor's designee within five business (5) days after such amount is due or if any other Rent or other sum payable to Lessor is not received by Lessor or Lessor's designee within five (5) business days after Lessor delivers a written notice to Lessee, Lessee shall pay to Lessor a late charge equal to five percent (5%) of such overdue amount. The parties hereby agree that such late charge represents a fair and reasonable estimate of the costs Lessor will incur by reason of late payments made by Lessee. Acceptance of such late charges by Lessor shall in no event constitute a waiver of Lessee's default with respect to such overdue amount, nor shall it prevent Page 2 [mission west properties/ standard lease v.4.0] Mosys draft lease 6/15/0

Such deficiency shall be calculated and paid monthly. Lessee shall also pay to.

However, nothing contained in this Section 16 shall require Lessee to pay any Federal or State income, franchise, estate, inheritance, succession, transfer or excess profits tax imposed upon Lessor.

If Lessee merges or sells substantially all of its assets and the net worth of the resulting entity is substantially less than that of Lessee, such sale shall be a default under this Lease unless approved by Lessor.21. Condemnation: If any part of the Premises shall be taken for any public or quasi-public use, under any statute or by right of eminent domain or private purchase in lieu thereof, and a part thereof remains which is susceptible of occupation hereunder, this Lease shall as to the part so taken, terminate as of the date title vests in the condemnor or purchaser, and the Rent payable hereunder shall be adjusted so that the Lessee shall be required to pay for the remainder of the Lease Term only that portion of Rent as the value of the part remaining. The rental adjustment resulting will be computed at the same Rental rate for the remaining part not taken; however, Lessor shall have the option to terminate this Lease as of the date when title to the part so taken vests in the condemnor or purchaser. If all of the Premises, or such part thereof be taken so that there does not remain a portion susceptible for occupation hereunder, this Lease shall thereupon terminate. If a part or all of the Premises be taken, all compensation awarded upon such taking shall be payable to the Lessor.

obligations of the Lessor hereunder. If any security is given by Lessee to secure the faithful performance of all or any of the covenants of this Lease on the part of Lessee, Lessor may transfer and deliver the security, as such, to the purchaser at any such sale of the building, and thereupon the Lessor shall be discharged from any further liability. 23. Subordination: This Lease, in the event Lessor notifies Lessee in writing, shall be subordinate to any ground lease, deed of trust, or other hypothecation for security now or hereafter placed upon the real property at which the Premises are a part and to any and all advances made on the security thereof and to renewals, modifications, replacements and extensions thereof. Lessee agrees to promptly execute any documents which may be required to effectuate such subordination. Notwithstanding such subordination, if Lessee is not in default and so long as Lessee shall pay the Rent and observe and perform all of the provisions and covenants required under this Lease, Lessee's right to quiet possession of the Premises shall not be disturbed or effected by any subordination. Lessor will upon signing of Lease, will use good faith and best efforts to obtain a commercial reasonably SNDA acceptable to both parties. 24. Waiver: The waiver by Lessor or Lessee of any breach of any term, covenant or condition, herein contained shall not be construed to be a waiver of such term, covenant or condition or any subsequent breach of the same or any other term, covenant or condition therein contained. The subsequent acceptance of Rent hereunder by Lessor shall not be deemed to be a waiver of Lessee's breach of any term, covenant, or condition of the Lease. 25. Holding Over: Any holding over after the end of the Lease Term requires Lessor's written approval prior to the end of the Lease Term, which, notwithstanding any other provisions of this Lease, Lessor may withhold. Such holding over shall be construed to be a tenancy at sufferance from month to month. Lessee shall pay to Lessor monthly base rent equal to one and one-half (1.5) times the monthly base rent installment due in the last month of the Lease Term and all other additional rent and all other terms and conditions of the Lease shall apply, so far as applicable. Holding over by Lessee without written approval of Lessor shall subject Lessee to the liabilities and obligations provided for in this Lease and by law, including, but not limited to those in Section 2.1 of this Lease. Lessee shall indemnify and hold Lessor harmless against any loss or liability resulting from any delay caused by Lessee in surrendering the Premises, including without limitation, any claims made or penalties incurred by any succeeding lessee or by Lessor.

Any such statement may be conclusively relied upon by any prospective purchaser or encumbrancer of the Premises. Lessee's failure to deliver such a statement within such time shall be conclusive upon the Lessee that (a) this Lease is in full force and effect, without modification except as may be represented by Lessor; (b) there are no uncured defaults in Lessor's performance. 28. Time: Time is of the essence of the Lease. Page 12 [mission west properties/ standard lease v.4.0] Mosys draft tease 6/15/0

Excepted Parties may have the benefit of the option rights. B. Extended Term Rent - Option Period: The monthly Rent for the Premises during the extended term shall equal 95% of the fair market monthly Rent for the Premises as of the exercise date of the extended term. Promptly upon Lessee's exercise of the option to extend, Lessee and Lessor shall meet and attempt to agree on the fair market monthly Rent for the Premises as of the commencement date of the extended term. In the event the parties fail to agree upon the amount of the monthly Rent for the extended term prior to commencement thereof, the monthly Rent for the extended term shall be determined by appraisal in the manner hereafter set forth. Annual base rent increases during the extended term shall be three and one-half percent (3.5%) per year. In the event it becomes necessary under this paragraph to determine the fair market monthly Rent of the Premises by appraisal, Lessor and Lessee each shall appoint a real estate appraiser within five days after Lessor or Lessee notifies the other party that the proposed rental rate for the extended term is unacceptable, who shall be a member of the American Institute of Real Estate Appraiser ("AIREA") and such appraisers shall each determine the fair market monthly Rent for the Premises taking into account the value of the Premises and the amenities provided by the outside areas, the common areas, and the building, and prevailing comparable Rentals in the area. Such appraisers shall, within twenty (20) business days after their appointment, complete their appraisals and submit their appraisal reports to Lessor and Lessee. If the fair market monthly Rent of the Premises established in the two (2) appraisals varies by five percent (5%) or less of the higher Rent, the average of the two shall be controlling. If said fair market monthly Rent varies by more than five percent (5%) of the higher Rental, said appraisers, within ten (10) days after submission of the last appraisal, shall appoint a third appraiser who shall be a member of the AIREA and who shall also be experienced in the appraisal of Rent values and adjustment practices for commercial properties in. the vicinity of the Premises. Such third appraiser shall, within twenty (20) business days after his appointment, determine by appraisal the fair market monthly Rent of the Premises taking into account the same factors referred to above, and submit his appraisal report to Lessor and Lessee. The fair market monthly Rent determined by the third appraiser for the Premises shall be controlling, unless it is less than that set forth in the lower appraisal previously obtained, in which case the value set forth in said lower appraisal shall be controlling, or unless it is greater than that set forth in the higher appraisal previously obtained in which case the Rent set for in said higher appraisal shall be controlling. If either Lessor or Lessee fails to appoint an appraiser, or if an appraiser appointed by either of them fails, after his appointment to submit his appraisal within the required period in accordance with the foregoing, the appraisal submitted by the appraiser properly appointed and timely submitting his appraisal shall be controlling. If the two appraisers appointed by Lessor and Lessee are unable to agree upon a third appraiser within the required period in accordance with the foregoing, application shall be made within twenty (20) days thereafter by either Lessor or Lessee to AIREA, which shall appoint a member of said institute willing to serve as appraiser. The cost of all appraisals under this subparagraph shall be borne equally be Lessor and Lessee. 36. Approvals: Whenever in this Lease the Lessor's or Lessee's consent is required, such consent shall not be unreasonably or arbitrarily withheld or delayed. In the event that the Lessor or Lessee does not respond to a request for any consents which may be required of it in this Lease within ten business days of the request of such consent in writing by the Lessee or Lessor, such consent shall be deemed to have been given by the Lessor or Lessee. 37. Authority: Each party executing this Lease represents and warrants that he or she is duly authorized to execute and deliver the Lease. If executed on behalf of a corporation, that the Lease is executed in accordance with the by-laws of said corporation (or a partnership that the Lease is executed in accordance with the partnership agreement of such partnership), that no Page 16[mission west properties/ standard lease v.4.0] Mosys draft lease 6/15/0
