EXHIBIT A

OPTION TO RENEW  ARBITRATED RENT: Lessee is given the option to extend the Term of Lease 2 subject to all of the provisions contained in Lease 2, except for monthly Base Rent, for a
period of two (2) years (Extension Term) following the expiration of the Term on May 31, 2012, by giving notice of exercise of the option (Option Notice) to Lessor at least six (6) months before
the expiration of the Term. If Lessee is in default beyond the applicable notice and cure periods on the date of giving the Option Notice, the Option Notice shall be totally ineffective. The Base Rent shall be set at the commencement of the
Extension Term at 95% of the fair market (based upon same or similar use) rent for renewals/extensions of similar premises in similar buildings in Fremont, California. The parties shall have fifteen (15) days after Lessor receives the Option
Notice in which to agree on monthly Base Rent during the Extension Term. If the parties agree on the monthly Base Rent for the Extension Term during that period, they shall immediately execute an amendment to the Lease stating the monthly Base Rent
for the Extension Term (provided however, failure of either party to execute such amendment shall not affect the exercise of the option by Lessee). If the parties are unable to agree on the monthly Base Rent for the Extension Term within that
period, then within ten (10) days after the expiration of that period, each party, at its cost and by giving notice to the other party, shall appoint a real estate appraiser with at least five (5) years full-time commercial appraisal
experience in the area in which the Premises are located, to appraise and set the monthly Base Rent for the Extension Term. If a party does not appoint an appraiser within ten (10) days after the other party has given notice of the name of its
appraiser, the single appraiser appointed shall be the sole appraiser and shall set the monthly Base Rent for the Extension Term. If the two appraisers



---

are appointed by the parties as stated in this paragraph they shall meet promptly and attempt to set the monthly Base Rent for the Extension Term. If they are unable to agree within thirty
(30) days after the second appraiser has been appointed, they shall attempt to elect a third appraiser meeting the qualifications stated in this paragraph within ten (10) days after the last day the two appraisers are given to set the
monthly Base Rent. If they are unable to agree on the third appraiser, either of the parties to the Lease, by giving ten (10) days notice to the other party can apply to the then President of the county real estate board of Alameda
County, or the Presiding Judge of the Superior Court of that County, for the selection of a third appraiser who meets the qualifications stated in this paragraph. Each of the parties shall bear one-half (1/2) of the cost of appointing the third
appraiser and of paying the third appraisers fee. The third appraiser, however selected, shall be a person who has not previously acted in any capacity for either party. Within thirty (30) days after the selection of the third appraiser,
the third appraiser shall choose a monthly Base Rent between the monthly Base Rents proposed by the first two appraisers and such figure shall be the monthly Base Rent for the Extension Term. In no event shall the Base Rent at the commencement of
the Extension Term be less than the Base Rent for the last month of the First Extension Term, plus $0.03/sf/month.
