If the Premises are ready for Tenant's occupancy prior to the Commencement Date, Landlord shall so notify Tenant and Tenant may accept such early occupancy, provided, however, in such event Tenant shall pay to Landlord base rental calculated on a daily basis assuming a 365 day year, for each day Tenant shall occupy the Premises prior to the Commencement Date.

AUDIT: If Tenant disputes the amount of operating expenses set forth in the invoice from the Landlord within forth-five days after receipt thereof, and provided Tenant is not then in default under this Lease, Tenant shall have the right upon notice to have Landlord's book and records relating to operating expenses audited by a qualified professional selected by Tenant or by Tenant itself. If after such audit Tenant still disputes the amount of operating expenses, a certification as to the proper amount shall be made by Landlord's independent certified public accountant in consulting with Tenant's professional, which certification shall be final and conclusive. If such audit reveals that operating expenses were overstated by five percent (5%) or more in the calendar year audited Landlord shall within thirty (30) days after 3 the certification pay to Tenant the amount of any overstatement which it had collected from Tenant. However, if such certification does not show that Landlord had made such an overstatement then Tenant shall pay both the costs of its professional as well as the reasonable charges of Landlord's independent certified public accountant engaged to determine the correct amount of operating expenses. If the certification shows that Landlord has undercharged Tenant then Tenant shall within thirty (30) days pay to Landlord the amount of any undercharge.

LATE PAYMENT OF RENT: All monthly installments of rent herein stipulated are due in advance without prior offset or deduction, except as set forth in this Lease, on the first (1st) day of each month during the term hereof, as set forth in Section 3 hereof entitled "BASE RENT." All rents not received on the first (1st) day of the month shall be deemed "past due" and all rents not received by the Landlord by the tenth (10th) day of each month during the term hereof shall be subject to a charge of 5% of the amount due. In any such event, Landlord shall so invoice Tenant for any such charge, which shall become due immediately upon Tenant's receipt of the invoice but in no event later than ten (10) days from the invoice date. Once any payment of rent is thirty (30) days past due, the total due, including the 5% charge, shall bear interest at eighteen (18) percent per annum. 7. NO ACCORD AND SATISFACTION: No acceptance by Landlord of a lesser sum than the Base Rent, late charges, additional rent and other sums then due shall be deemed to be other than on account of the earliest installment of such payments due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment be deemed as accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord's right to recover the balance of such installment or pursue any other remedy in this Lease provided. 8. USE: Premises shall be sued for such office, assembly, storage, distribution and manufacturing activities as are allowed under existing zoning and recorded covenants. Tenant shall not conduct, or allow to be conducted, on or within the Premises any business or permit any act which in any way increases the cost of fire insurance on the building or constitutes a nuisance or is contrary to or in violation of the laws, statutes or ordinances of local state or federal governments having jurisdiction and Tenant agrees to comply, at Tenant's expense, with all governmental regulations, to include those relating to the American with Disabilities Act (ADA). Tenant will pay to bring the Premises into compliance with any revisions to the American with Disabilities Act (ADA) after the Commencement Date of the Lease. Any violation of this provision by Tenant shall be a material breach of this Lease, entitling Landlord to exercise any rights or remedies contained herein or provided by law or other authority. Landlord and Tenant hereby agree that the manufacturing of wafers as contemplated by the Tenant does not violate existing zoning or any recorded restrictive covenants. 4 It is hereby agreed and understood that the following functions are prohibited outside the building walls or in the parking or service areas: storage of any item; manufacture or assembly of any product; refuse accumulation; rallies or meetings; any conduct of business.

Tenants agree to abide by and conform to such rules and regulations and shall be responsible for the compliance with same by its employees, agents, customers and invitees. The failure of Landlord to enforce any of such Rules and Regulations against Tenant or any other tenant shall not be deemed to be a waiver of same. Landlord shall have the right to restrict or close all or any portion of the common areas at such times and for such periods as may, in the opinion of the Landlord, be necessary to prevent a dedication thereof, or to preserve the status thereof as private property, or to prevent the accrual of any rights in any person; and Landlord may also close said common areas for purposes of maintenance and repair as may be required from time to time. Tenant shall pay to Landlord its proportionate share of the entire common area maintenance cost.

During the term hereof, Landlord shall notify Tenant of its proportionate share due for such cost. Landlord shall have the option through the Lease term to require Tenant's reimbursement on either a monthly, quarterly or annual basis, at Landlord's sole discretion, to become due and payable as additional rent within ten (10) days, if invoiced monthly or thirty (30) days, if invoiced quarterly or annually, from the date of invoice. 11. ASSIGNMENT AND SUBLETTING: Tenant covenants and agrees that neither this Lease nor the term hereby granted, nor any part thereof, will be assigned, mortgaged, pledged, encumbered o otherwise transferred, by operation of law or otherwise, and that neither the Premises, nor any part thereof, will be sublet or advertised for subletting or occupied, by anyone other than Tenant, or for any purpose other than as hereinabove set forth, without the prior written consent of Landlord not to be unreasonably withheld. Landlord's withholding of consent shall be deemed reasonable if the use or occupancy of the Premises by such sublessee or assignee could make Landlord responsible for any costs of compliance with the Americans with Disabilities Act (ADA) or any other legislation by any governmental body. 12. LANDLORD'S REPAIRS: The Landlord shall maintain and keep in good condition and repair the roof, parking areas and exterior landscaping, exterior and supporting walls of the Building together with repairs necessary due to structural defects, if any.

To the extent any repairs required to be performed by the Landlord are required, the Tenant shall immediately notify the Landlord that such repairs are necessary. Provided Tenant's request is reasonable, Landlord shall immediately commence such repairs and complete such repairs as soon as possible. Tenant shall have the right to complete any repairs not completed by the Landlord in a timely fashion, and offset such cost in the next month's rent (not to exceed one month). Tenant shall provide to Landlord written documentation of said costs. 13. TENANT REPAIRS; ALTERATIONS: The Tenant shall effect, at its sole cost and expense, all maintenance and repairs to the interior of said Premises, including without limitation, the floor and wall coverings (whether paint or otherwise); lights, light fixtures, and light bulbs; interior and exterior doors and door locks, overhead doors; ceiling tiles; water heaters; windows, frames, glass, window blinds; all heating, ventilating and air conditioning equipment; all plumbing and electrical not described in Section 12 above; security systems and any other improvements not required to be maintained by Landlord in the immediately preceding Section 12 hereof, except in the event the improvements installed by Landlord may be defective in material or labor in installation. All such repairs and replacements required by this section shall be made only by persons approved in advance by Landlord, not to be unreasonably withheld. Should Tenant fail to comply with the maintenance and repairs required above, the Landlord shall have the right, after ten (10) days prior written notice to Tenant, to enter on the Premises and make necessary repairs and perform and maintenance required. Any reasonable cost incurred by Landlord shall be paid by the Tenant at cost plus ten percent (10%) overhead and ten percent (10%) for profit. Tenant shall submit to the Landlord for Landlords' prior written approval all of the plans and specifications for any alterations, additions or improvements in and to the Premises which tenant may deem desirable or necessary in its use and occupancy thereof. Such alterations, additions or improvements shall not be made without the prior written approval of Landlord. If any changes are made to the plans by the Landlord, Tenant shall review final plans and provide written approval prior to Landlord starting upfit construction. All such alterations, additions or improvements shall be made in accordance with applicable city, county, state and federal laws and ordinances, and building and zoning rules and regulations and all present and future governmental regulations relating to the Americans with Disabilities Act (ADA). Landlord's approval hereunder shall not be deemed as warranty that tenant's alterations meet such ADA regulations, however, such consent shall carry a requirement that such alterations will be constructed by Tenant, at its own expense, in full compliance with all existing ADA governmental regulations. Tenant shall be liable for all damages or injuries which may result to any person or property by reason of or resulting from any alterations, additions or improvements made by it to the Premises and shall hold the Landlord harmless with respect thereto. All additions and improvements made by the Tenant, except trade fixtures, shall become a part of the Premises and shall, upon the termination or expiration of this Lease, belong to Landlord except as may be otherwise set forth in a letter agreement or other written instrument executed by the parties hereto and attached to this Lease as an amendment hereto and thereby made a part hereof. In the event Tenant performs any alterations, additions or improvements to the Premises, Tenant agrees that it shall provide to Landlord a reproducible set of as-built plans for Landlord's files. If Tenant fails to perform Tenant's obligations under this Section, Landlord may at its option enter upon the Premises after ten (10) days prior written notice to Tenant, perform such obligation on Tenant's behalf, and the cost thereof together with interest thereon shall become due and payable as additional rental to Landlord together with Tenant's next rental installment. At Landlord's option, Landlord may require that Tenant remove any or all alterations or improvements at Tenant's expense upon termination of the Lease. 14. HEATING, VENTILATION AND AIR CONDITIONING: The Tenant shall at its sole cost and expense keep in force a maintenance contract for the entire term of this Lease on all heating, air conditioning and ventilation equipment pertaining to the Premises, providing for service inspections to be done on a routine basis as proposed by such contract. Tenant shall submit a copy of said contract to Landlord within ten (10) days after occupancy of the Premises. Landlord 6 must approve the terms of the maintenance contract and the firm Tenant chooses as the maintenance contractor, such approval not to be unreasonably withheld. Landlord shall be responsible for replacement of any defective motor or compressor within the system provided it is not as a result of negligence or willful act of the Tenant, its clients, customers, licensees, assignees, agents, employees, or invitees. However, Tenant's failure to provide the required maintenance contract shall release Landlord from any and all liability for said equipment. Upon termination of this Lease, Tenant will deliver the HVAC equipment in good operating condition. 15. FEDERAL REGULATION AND/OR PROHIBITION OF CFC's: Due to an environmental threat that the earth's ozone layer has deteriorated, there is international concern for the control of Chlorofluorocarbons ("CFC's") and possible ban thereof. Future legislation could impose: 1) New maintenance standards and procedures on HVAC equipment in order to reduce the amount of freon existing in the system; or 2) Conversion of the equipment in order to accommodate the use of a substitute chemical; or (3) Replacement of the equipment in the event the equipment does not comply with the required performance and maintenance standards. Landlord and Tenant hereby acknowledge that any costs associated with the above shall be considered a maintenance item and shall be paid by Tenant. Notwithstanding the preceding sentence, in the event that any such rules and regulations as described above are enacted which require significant changes to the HVAC equipment of the Premises during the last three years of the term of this Lease (including the renewal term), the cost of bringing the HVAC equipment on the Premises into compliance with such rules or regulations shall be prorated among the Tenant and the Landlord based upon the anticipated useful life of the HVAC equipment, as modified, and the remaining number of years left in the term of this Lease. 16. SUBORDINATION AND ATTORNMENT: Tenant agrees that this Lease is subject and subordinate to any and all mortgages or deeds of trust now or hereafter placed on the property of which the Premises are a part, and this clause shall be self operative without any further instrument necessary to effect such subordination; however, if requested by Landlord, Tenant shall promptly execute and deliver to Landlord any such certificate as Landlord may reasonably request evidencing such subordination of this Lease to or the assignment of this Lease as additional security for such mortgages or deeds of trust. Provided, however, in each case, the holder of the mortgage or deed of trust shall agree that this Lease shall not be divested by foreclosures or other default proceedings so long as tenant shall not be in default under the terms of this Lease beyond any applicable cure period set forth in this Lease. Tenant shall continue its obligations under this Lease in full force and effect notwithstanding any such default proceedings under a mortgage or deed of trust and shall attorn to the mortgagee, trustee or beneficiary of such mortgage or deed of trust, and their successors or assigns, and to the transferee under any foreclosure or default proceedings. The subordination contained in this paragraph 16 shall not apply unless and until the mortgagee or deed of trust holder agrees to the nondisturbance provisions set forth above. In the event of the sale, assignment, or transfer by Landlord of its interest in the Premises to a successor in interest who expressly assumes the obligation of the Landlord hereunder, and who is financially sound and adequately capitalized, the Landlord shall thereupon be released or discharged from all of its covenants and obligations hereunder, except such obligations shall have accrued prior to any such sale, assignment or transfer; and Tenant agrees to look solely to any successor in interest of the Landlord for performance of any such obligations. Tenant shall have ten (10) days from its receipt of Landlord's request to deliver any such fully executed documents to Landlord. Tenant's failure to execute and deliver any such documents shall constitute a default hereunder. 7 17. CHANGE IN OWNERSHIP OF PREMISES: If the ownership of the Premises or the name or address of the party entitled to receive rent hereunder shall be changed, the Tenant may, until receipt of proper notice of such change(s), continue to pay the rent and other charges herein reserved accrued and to accrue hereunder to the party to whom and in the manner in which the last preceding installment of rent or other charge was paid, and each such payment shall, to the extent thereof, exonerate and discharge the Tenant. 18. CONDEMNATION: If the whole of the Building, or such substantial portion thereof as will make Premises unusable for the purposes referred to herein, shall be condemned by any legally constituted authority for any public use or purpose, then in either of said events the term hereby granted shall cease from the time when possession thereof is taken by the condemning authority, and rental shall be accounted for as between Landlord and Tenant as of that date. In the event the portion condemned is such that the remaining portion can, after restoration and repaid, be made usable for Tenant's purposes, then this Lease shall not terminate; however, the rent shall be reduced equitably to the amount of the Premises taken. In such an event, Landlord shall make such repairs as may be necessary as soon as the same can be reasonably accomplished, not to exceed 120 days. Such termination, however, shall be without prejudice to the rights of either Landlord or Tenant, or both, to recover compensation and damage caused by condemnation from the condemnor. It is further understood and agreed that neither the Tenant nor Landlord shall have any rights in any award made to the other by any condemnation authority. Any minor condemnation or taking of the Premises for the construction or maintenance of streets or highways shall not be considered a condemnation or taking for the purposes of this Section 18 so long as the Premises shall not be materially or adversely affected, ingress and egress for the remainder of the Premises shall be adequate for the business of Tenant, and the provisions of any loan documents of Landlord's lender which encumber the Premises are complied with, and provided sufficient parking spaces remain as required under applicable zoning requirements. 19. RIGHT OF LANDLORD TO ENTER; "FOR RENT" SIGNS: The Tenant agrees that the Landlord or its agents may at all reasonable times enter upon the Premises for the purpose of inspection or repair of the Building or the building systems and such other purposes as Landlord may deem necessary or proper for the reasonable protection of Landlord's interest in the Premises. In addition, the Landlord may enter the Premises at all reasonable times to exhibit the Premises to prospective purchasers. During the two (2) months immediately preceding the final expiration of the term created hereunder or any renewal thereof, the Landlord, may exhibit the Premises to prospective tenants and/or affix a notice that the Premises are for rent; such notice shall not be greater than four (4) square fee in area, and shall be affixed to a suitable part thereof, exclusive of doors and windows and so as not to obstruct the Tenant's signs. 20. TAXES: Tenant agrees to pay before they become delinquent all taxes, assessments and governmental charges of any kind and nature whatsoever (hereinafter referred to as "taxes") lawfully levied or assessed against the Premises during the term of the Lease. To the extent that taxes are levied or assessed for any year in which the Tenant occupies the Premises for only a portion of such year, taxes shall be prorated between the Tenant and the Landlord based upon the actual number of days that the Tenant occupies the Premises during such year. If at any time during the term of this Lease, the present method of taxation shall be changed so that in lieu of the whole or any part of any taxes, assessments or governmental charges levied, assessed or imposed on real estate and the improvements thereof, there shall be levied, assessed or imposed on Landlord a capital levy or other tax directly on the rents received therefrom and/or a franchise tax, assessment levy or charge measured by or based, in whole or in part, upon such rents for the present or any future building or building on the Premises, then all such taxes, assessments, levies or charges, or the part thereof so measured or based, shall be deemed to be included with the term "taxes" for the purposes hereof. Tenant shall pay to Landlord its proportionate share of the entire cost of all taxes referenced herein. Tenant's proportionate share shall be the relation of Tenant's 136,000 rentable square foot area to the 136,000 rentable square feet of total building area, or 100%. Real estate taxes, as referenced herein, shall be defined as the amount of the total tax invoice (property assessment x tax rate) and shall exclude any discount or late penalty charge and shall include any charge or fee incurred by Landlord as a result of its attempt in securing a reduction in the assessed value of the Property. 8 During the term hereof, Landlord shall notify Tenant of its proportionate share due for such cost. Landlord shall have the option through the Lease term to require Tenant's reimbursement on either a monthly, quarterly or annual basis, at Landlord's sole discretion, to become due and payable as additional rent within ten (10) days, if invoiced monthly or thirty (30) days if invoiced quarterly or annually from the date of invoice. 21. FIRE, EXTENDED COVERAGE AND LIABILITY INSURANCE: Landlord agrees to keep in force policies of fire and extended coverage insurance which shall insure the Building against such perils or loss as Landlord may deem appropriate including loss of rents, vandalism and malicious mischief, in an amount equal to one hundred percent (100%) of the replacement cost of the Building and the improvements installed by Landlord. Landlord shall deliver certificates of such insurance to Tenant prior to commencement of this Lease and at least ten days prior to expiration of any existing certificate. Such certificate shall provide that the insurance cannot be terminated by the insurer without providing thirty (30) days prior written notice to Tenant. Tenant agrees to maintain and keep in force, at its expense and throughout the entire term hereof, insurance against fire and such other risks as are from time to time included in standard extended coverage endorsements including vandalism and malicious mischief, insuring Tenant's stock-in-trade, trade fixtures, furniture, furnishings, special equipment and all other items of personal property of Tenant located on or within the Premises and all such other improvements as are made by the Tenant to the Premises.

In addition thereto, Tenant shall provide "umbrella coverage" in the amount of One Million Dollars ($1,000,000.00). The Tenant shall, in addition, name the Landlord as an additional insured under such liability policies and shall provide the Landlord a certificate of same within thirty (30) days after the execution of this Lease, as shown on Exhibit "D". Tenant agrees to pay to the Landlord its proportionate share of the entire cost that Landlord may incur in the cost of maintaining the policies required hereunder. Tenant's proportionate share shall be the relation of Tenant's rentable square foot area to the 136,000 rentable square feet of total building area, or 100%. During the term hereof, Landlord shall notify Tenant of its proportionate share due for such cost.

DAMAGE AND DESTRUCTION: If the Building, improvements or other portions of the Premises are rendered partially or wholly untenantable from fire or other casualty, and if such damage cannot, in Landlord's reasonable estimation, be materially restored within one hundred eighty (180) days of such damage, then Landlord may, in its sole option, terminate this Lease as of the date of such fire or casualty. For purposes hereof, the Building, or other portions of the Premises shall be deemed "materially restored" if they are in such condition as would not prevent or materially interfere with tenant's use of the Premises for the purpose for which it was then being used. If this Lease is not terminated pursuant to the above paragraph, then Landlord shall proceed with all due diligence to repair and restore the Building, at Landlord's cost, once it has been assured of the existence of and payment of the insurance proceeds (except that Landlord may elect not to rebuild if such damage occurs during the last year of the term of the Lease exclusive of any option which is unexercised at the data of such damage). 9 If this Lease is not terminated pursuant to the above paragraph, the term of this Lease shall end on the date of such damage as if the date had been originally fixed in this Lease for the expiration of term hereof. If the Lease shall not be terminated by Landlord pursuant to the above paragraph and in the event that the Landlord should fail to complete such repairs and material restoration within one hundred eighty (180) days after the date of such damage, Tenant may at its option and as its sole remedy terminate this Lease by delivering written notice to Landlord whereupon the Lease shall end on the date of such notice as if the date of such notice where originally fixed in this Lease for the expiration of the term hereof; provided, however, that if construction is delayed because of changes, deletions or additions in construction requested by Tenant strikes, lockouts, casualties, acts of God, war, material or labor shortages, governmental regulation or control or other causes beyond the reasonable control of Landlord, the period for restoration, repair of rebuilding shall be extended for the amount of time Landlord is so delayed.
