If Tenant intends to sublet Premises and Landlord elects to terminate this Lease, this Lease shall be terminated on the date specified in Tenant's notice. If, however, this Lease shall terminate pursuant to the foregoing with respect to less than all the Premises, the rent as defined and reserved hereinabove shall be adjusted on a pro rata basis to the number of square feet retained by Tenant, and this Lease as so amended shall continue in full force and effect. In the event Tenant is allowed to assign, transfer or sublet the whole or any part of the Premise, with the prior written consent of Landlord, no assignee, transferee or subtenant shall assign or transfer this Lease, either in whole or in part, or sublet the whole or any part of the Premises without having obtained prior written consent of Landlord which consent shall not be unreasonably withheld. A consent of Landlord to one assignment, transfer, hypothecation, subletting, occupation or use without such consent shall be void and shall constitute a breach of this Lease by Tenant and shall, if the option of Landlord exercised by written notice to Tenant, terminate this Lease. The leasehold estate under this Lease shall not shall any interest therein, be assignable for any purpose by operation of law without the written consent of Landlord which consent shall not be unreasonably withheld. As a condition to its consent,

Landlord may require Tenant to pay all expenses in connection with the assignment, and Landlord may require Tenant's assignee or transferee (or other assignees or transferees) to assume in writing all of the obligations under this Lease and for Tenant to remain liable to Landlord under the Lease.

00. SUBORDINATION AND MORTGAGES In the event Landlord's title or leasehold interest is now or hereafter encumbered by a deed of trust, upon the interest of Landlord in the land and buildings in which the demised Premises are located, to secure a loan from a lender thereinafter referred to as "Lender" to Landlord, Tenant shall, at the request of Landlord or Lender, execute in writing an agreement (in form reasonably acceptable to Tenant) subordinating its rights under this Lease to the lien of such deed of trust, or, if so requested, agreeing that the lien of Lender's deed of trust shall be or remain subject and subordinate to the rights of Tenant under this Lease. Notwithstanding any such subordination, Tenant's possession under this Lease shall not be disputed if Tenant is not in default and so long as Tenant shall pay all rent and observe and perform all of the provisions set forth in this Lease and any Subordination agreement shall reflect the agreement of the Lender to the same. SEE XXXXXXXXX 00

00. ENTRY BY LANDLORD Landlord reserves, and shall at all reasonable times after at least 24 hours notice (except in emergencies) have, the right to enter the Premises to inspect them; to perform any services to be provided by Landlord hereunder; to make repairs or provide any services to a contiguous tenant(s); to submit the Premises to prospective purchasers, mortgagors or tenants; to post notices of nonresponsibility; and to alter, improve or repair the Premises or other parts of the building, all without abatement of rent, and may erect scaffolding and other necessary structures in or through the Premises where reasonably required by the character of the work to be performed provided, however that the business of Tenant shall be interfered with to the least extent that is reasonably practical. Any entry to the Premises by Landlord for the purposes provided for herein shall not under any circumstances be construed or deemed to be a forcible or unlawful entry into or a detainer of the Premises or an eviction, actual or constructive, of Tenant from the premises or any portion thereof.

19. BANKRUPTCY AND DEFAULT The commencement of a bankruptcy action or liquidation action or reorganization action or insolvency action or an assignment of or by Tenant for the benefit of creditors, or any similar action undertaken by Tenant, or the insolvency of Tenant, shall, at Landlord's option, constitute a breach of this Lease by Tenant. If the trustee or receiver appointed to serve during a bankruptcy, liquidation, reorganization, insolvency or similar action elects to reject Tenant's unexpired Lease, the trustee or receiver shall notify Landlord in writing of its election within thirty (30) days after an order for relief in a liquidation action or within thirty (30) days after the commencement of any action.

Within thirty (30) days after court approval of the assumption of this Lease, the trustee or receiver shall cure (or provide adequate assurance to the reasonable satisfaction of Landlord that the trustee or receiver shall cure) any and all previous defaults under the unexpired Lease and shall compensate Landlord for all actual pecuniary loss and shall provide adequate assurance of future performance under said Lease to the reasonable satisfaction of Landlord. Adequate assurance of future performance, as used herein, includes, but shall not be limited to: (i) assurance of source and payment of rent, and other consideration due under this Lease; (ii) assurance that the assumption or assignment of this Lease will not breach substantially any provision, such as radius, location, use, or exclusivity provision, in any agreement relating to the above described Premises.

Nothing contained in this section shall affect the existing right of Landlord to refuse to accept an assignment upon commencement of or in connection with a bankruptcy, liquidation, reorganization or insolvency action or an assignment of Tenant for the benefit of creditors or other similar act. Nothing contained in this Lease shall be construed as giving or granting or creating an equity in the demised Premises to Tenant. In no event shall the leasehold estate under this Lease, or any interest therein, be assigned by voluntary or involuntary bankruptcy proceeding without the prior written consent of Landlord. In no event shall this Lease or any rights or privileges hereunder be an asset of Tenant under any bankruptcy, insolvency or reorganization proceedings.

The failure to perform or honor any covenant, condition or representation made under this Lease shall constitute a default hereunder by Tenant upon expiration of the appropriate grace period hereinafter provided. Tenant shall have a period of five (5) business days from the date of written notice from Landlord within which to cure any default in the payment of rental or adjustment thereto. Tenant shall have a period of thirty (30) days from the date of written notice from Landlord within which to cure any other default under this Lease; provided, however, that if the nature of Tenant's failure is such that more than thirty days is reasonably required to cure the same, Tenant shall not be in default so long as Tenant commences performance within such thirty day period and thereafter prosecutes the same to completion.

Upon an uncured default of this Lease by Tenant, Landlord shall have the following rights and remedies in addition to any other rights or remedies available to Landlord at law or in equity:

(a) The rights and remedies provided for by California Civil Code Section 1951.2, including but not limited to, recovery of the worth at the time of award of the amount by which the unpaid rent for the balance of the term after the time of award exceeds the amount of rental loss for the same period that Tenant proves could be reasonably avoided, as computed pursuant to subsection (b) of said Section 1951.2. Any proof by Tenant under subparagraphs (2) and (3) of Section 1951.2 of the California Civil Code of the amount of rental loss that could be reasonably avoided shall be made in the following manner: Landlord and Tenant shall each select a licensed real estate broker in the business of renting property of the same type and use as the Premises and in the same geographic vicinity. Such two real estate brokers shall select a third licensed real estate broker, and the three licensed real estate brokers so selected shall determine the amount of the rental loss that could be reasonably avoided from the balance of the term of this Lease after the time of award. The decision of the majority of said licensed real estate brokers shall be final and binding upon the parties hereto.

(b) The rights and remedies provided by California Civil Code Section which allows Landlord to continue the Lease in effect and to enforce all of its rights and remedies under this Lease, including the right to recover rent as it becomes due, for so long as Landlord does not terminate Tenant's right to possession; acts of maintenance or preservation, efforts to relet the Premises, or the appointment of a receiver upon Landlord's initiative to protect its interest under this Lease shall not constitute a termination of Tenant's right to possession.

(d) To the extent permitted by law the right and power, to enter the Premises and remove therefrom all persons and property, to store such property in a public warehouse or elsewhere at the cost of and for the account of Tenant, and to sell such property and apply such proceeds therefrom pursuant to applicable California law, Landlord may from time to time sublet the premises or any part thereof for such term or terms (which may extend beyond the term of this Lease) and at such rent and such other terms as Landlord in its reasonable sole discretion may deem advisable, with the right to make alterations and repairs to the Premises. Upon each subletting, (i) Tenant shall be immediately liable to pay Landlord, in addition to indebtedness other than rent due hereunder, the reasonable cost of such subletting, including, but not limited to, reasonable attorneys' fees, and any real estate commissions actually paid, and the cost of such reasonable alterations and repairs incurred by Landlord and the amount, if any, by which the rent hereunder for the period of such subletting (to the extent such period does not exceed the term hereof) exceeds the amount to be paid as rent for the Premises of such period or (ii) at the option of Landlord, rents received from such subletting shall be applied first to payment of indebtedness other than rent due hereunder from Tenant to Landlord; second, to the payment of any costs of such subletting and of such alterations and repairs; third to payment of rent due and

unpaid hereunder; and the residue, if any, shall be held by Landlord and applied in payment of future rent as the same becomes due hereunder. If Tenant has been credited with any rent to be received by such subletting under option (i) and such rent shall not be promptly paid to Landlord by the subtenant(s), or if such rentals received from such subletting under option (ii) during any month be less than that to be paid during that month by Tenant hereunder, Tenant shall pay any such deficiency to Landlord. Such deficiency shall be calculated and paid monthly. No taking possession of the Premises by Landlord shall be construed as an election on its part to terminate this Lease unless a written notice of such intention be given to Tenant. Notwithstanding any such subletting without termination, Landlord may at any time hereafter elect to terminate this Lease for such previous breach.

(e) The right to have a receiver appointed for Tenant upon application by Landlord, to take possession of the Premises and to apply any rental collected from the premises and to exercise all other rights and remedies granted to Landlord pursuant to subparagraph d above.

20. ABANDONMENT Tenant shall not vacate or abandon the Premises at any time during the term of this Lease (except that Tenant may vacate so long as it pays Rent, provides a security service to check the Premises during normal business hours from Monday to Friday, and otherwise performs its obligations hereunder) and if Tenant shall abandon, vacate or surrender said Premises, or be dispossessed by the process of law, or otherwise, any personal property belonging to Tenant and left on the Premises shall be deemed to be abandoned, at the option of Landlord, except such property as may be mortgaged to Landlord.

21. DESTRUCTION In the event the Premises are destroyed in whole or in part from any cause, except for routine maintenance and repairs and incidental damage and destruction or caused from vandalism and accidents for which Tenant is responsible under Xxxxxxxxx 0, Xxxxxxxx may, at its option:

(a) Rebuild or restore the Premises to their condition prior to the damage or destruction, or

(b) Terminate this Lease, (providing that the Premises is damaged to the extent of 33¹/3% of the replacement cost. If Landlord does not give Tenant notice in writing within thirty (30) days from the destruction of the Premises of its election to either rebuild and restore them or to terminate this Lease, Landlord shall be deemed to have elected to rebuild or restore them, in which event Landlord agrees, at its expense promptly to rebuild or restore the premises to their condition prior to the damage or destruction. Tenant shall be entitled to a reduction in rent while such repair is being made in the proportion that the area of the Premises rendered untenantable by such damage bears to the total area of the Premises. If it is reasonably estimated by Landlord that the rebuilding or restoration will exceed 180 days or if Landlord does not complete the rebuilding or restoration within one hundred eighty (180) days following the date of destruction (such period of time to be extended for delays caused by the fault or neglect of Tenant or because of subsequent acts of God, acts of public agencies, labor disputes, strikes, fires, freight embargos, rainy or stormy weather, inability to obtain materials, supplies or fuels, acts of contractors or subcontractors, or delay of the contractors or subcontractors due to such causes or other contingencies beyond the control of Landlord), then Tenant shall have the right to terminate this Lease by giving fifteen (15) days prior written notice to Landlord. Notwithstanding anything herein to the contrary, Landlord's obligation to rebuild or restore shall be limited to the building and interior improvements constructed by Landlord as they existed as of the commencement date of the Lease and shall not include restoration of Tenant's trade fixtures, equipment, merchandise, or any improvements, alterations or additions made by Tenant to the Premises, which Tenant shall forthwith replace or fully repair at Tenant's sole cost and expense provided this Lease is not cancelled according to the provisions above.

Unless this Lease is terminated pursuant to the foregoing provisions, this Lease shall remain in full force and effect. Tenant hereby expressly waives the provisions of Section 1932, Subdivision 2, in Section 1933, Subdivision 4 of the California Civil Code.

In the event that the building in which the Premises are situated is damaged or destroyed to the extent of not less than 33¹/3% of the replacement cost thereof, Landlord may elect to terminate this Lease, whether the Premises be injured or not.

22. EMINENT DOMAIN If all or any part of the Premises shall be taken by any public or quasi-public authority under the power of eminent domain or conveyance in lieu thereof, this Lease shall terminate as to any portion of the Premises so taken or conveyed on the date when title vests in the condemnor, and Landlord shall be entitled to any and all payment, income, rent, award, or any interest therein whatsoever which may be paid or made in connection with such taking or conveyance, and Tenant shall have no claim against Landlord or otherwise for the value of any unexpired term of this Lease. Notwithstanding the foregoing paragraph, any compensation specifically awarded Tenant for loss of business, Tenant's personal property, moving cost or loss of goodwill, shall be and remain the property of Tenant.

If any action or proceeding is commenced for such taking of the Premises or any material part thereof, then Landlord shall have the right to terminate this Lease by giving Tenant written notice thereof within sixty (60) days of the date of receipt of said written advice, or commencement of said action or proceeding, or taking conveyance, which termination shall take place as of the first to occur of the last day of the calendar month next following the month in which such notice is given or the date on which title to the Premises shall vest in the condemnor.

In the event of such a partial taking or conveyance of the Premises, if the portion of the Premises taken or conveyed is so substantial that the Tenant can no longer reasonably conduct its business, Tenant shall have the privilege of terminating this Lease within sixty (60) days from the date of such taking or conveyance, upon written notice to Landlord of its intention to do so, and upon giving of such notice this Lease shall terminate on the last day of the calendar month next following the month in which such notice is given, upon payment by Tenant of the rent from the date of such taking or conveyance to the date of termination.

If a portion of the Premises be taken by condemnation or conveyance in lieu thereof and neither Landlord nor Tenant shall terminate this Lease as provided herein, this Lease shall continue in full force and effect as to the part of the Premises not so taken or conveyed, and the rent herein shall be apportioned as of the date of such taking or conveyance so that thereafter the rent to be paid by Tenant shall be in the ratio that the area of the portion of the Premises not so taken or conveyed bears to the total area of the Premises prior to such taking.

23. SALE OR CONVEYANCE BY LANDLORD In the event of a sale or conveyance of the Premises or any interest therein, by any owner of the reversion then constituting Landlord, the transferor shall thereby be released as to such interest transferred from any further liability upon any of the terms, covenants or conditions (express or implied) herein contained in favor of Tenant, and in such event, insofar as such transfer is concerned, Tenant agrees to look solely to the responsibility of the successor in interest of such transferor in and to the Premises and this Lease. This Lease shall not be affected by any such sale or conveyance, and Tenant agrees to attorn to the successor in interest of such transferor.

24. ATTORNMENT TO LENDER OR THIRD PARTY In the event the interest of Landlord in the land and buildings in which the leased Premises are located (whether such interest of Landlord is a fee title interest or a leasehold interest) is encumbered by deed of trust, and such interest is acquired by the lender or any third party through judicial foreclosure or by exercise of a power of sale at private trustee's foreclosure sale, Tenant hereby agrees to attorn to the purchaser at any such foreclosure sale and to recognize such purchaser as the Landlord under this Lease. In the event the lien of the deed of

trust securing the loan from a Lender to Landlord is prior and paramount to the Lease, this Lease shall nonetheless continue in full force and effect for the remainder of the unexpired term hereof, at the same rental herein reserved and upon all the other terms, conditions and covenants herein contained.

25. HOLDING OVER Any holding over by Tenant after expiration or other termination of the term of this Lease with the written consent of Landlord delivered to Tenant shall not constitute a renewal or extension of the Lease or give Tenant any rights in or to the leased Premises except as expressly provided in this Lease. Any holding over after the expiration or other termination of the term of this Lease, with the consent of Landlord, shall be construed to be a tenancy from month to month, on the same terms and conditions herein specified insofar as applicable except that the monthly Basic Rent shall be increased to an amount equal to one hundred fifty (150%) percent of the monthly Basic Rent required during the last month of the Lease term.

26. CERTIFICATE OF ESTOPPEL Tenant shall at any time upon not less than ten (10) days prior written notice from Landlord execute, acknowledge and deliver to Landlord a statement in writing (i) certifying that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease, as so modified, is in full force and effect) and the date to which the rent and other charges are paid in advance, if any, and (ii) acknowledging that there are not, to Tenant's knowledge, any uncured defaults on the part of the Landlord hereunder, or specifying such defaults, if any are claimed. Any such statement may be conclusively relied upon by any prospective purchaser or encumbrancer of the Premises. Tenant's failure to deliver such statement within such time shall be conclusive upon Tenant that this Lease is in full force and effect without modification except as may be represented by Landlord; that there are no uncured defaults in Landlord's performance, and that not more than one month's rent has been paid in advance.

27. CONSTRUCTION CHANGES It is understood that the description of the Premises and the location of ductwork, plumbing and other facilities therein are subject to such minor changes as Landlord or Landlord's architect determines to be desirable in the course of construction of the Premises, and no such changes shall effect this Lease or entitle Tenant to any reduction of rent hereunder or result in any liability of Landlord to Tenant. Landlord does not guarantee the accuracy of any drawings supplied to Tenant and verification of the accuracy of such drawings rests with Tenant.

28. RIGHT OF LANDLORD TO PERFORM All terms, covenants and conditions of this Lease to be performed or observed by Tenant shall be performed or observed by Tenant at Tenant's sole cost and expense and without any reduction of rent. If Tenant shall fail to pay any sum of money, or other rent, required to be paid by it hereunder and such failure shall continue for five (5) days after written notice by Landlord, or shall fail to perform any other term or covenant hereunder on its part to be performed, and such failure shall continue for thirty (30) days after written notice thereof by Landlord, Landlord, without waiving or releasing Tenant from any obligation of Tenant hereunder, may, but shall not be obliged to, make any such payment or perform any such other term or covenant on Tenant's part to be performed. All sums so paid by Landlord and all necessary costs of such performance by Landlord together with interest thereon at the rate of the prime rate of interest per annum as quoted by the Bank of America from the date of such payment or performance by Landlord, shall be paid (and Tenant covenants to make such payment) to Landlord within five (5) business days after demand by Landlord, and Landlord shall have (in addition to any other right or remedy of Landlord) the same rights and remedies in the event of nonpayment by Tenant as in the case of failure by Tenant in the payment of rent hereunder.

29. ATTORNEYS' FEES

A. In the event that either Landlord or Tenant should bring suit for the possession of the Premises, for the recovery of any sum due under this Lease, or because of the breach of any provision of this Lease, or for any other relief against the other party hereunder, then all costs and expenses,

including reasonable attorneys' fees, incurred by the prevailing party therein shall be paid by the other party, which obligation on the part of the other party shall be deemed to have accrued on the date of the commencement of such action and shall be enforceable whether or not the action is prosecuted to judgment.

B. Should Landlord be named as a defendant in any suit brought against Tenant in connection with or arising out of Tenant's occupancy hereunder, Tenant shall pay to Landlord its costs and expenses incurred in such suit, including a reasonable attorney's fee.

30. WAIVER The waiver by either party of the other party's failure to perform or observe any term, covenant or condition herein contained to be performed or observed by such waiving party shall not be deemed to be a waiver of such term, covenant or condition or of any subsequent failure of the party failing to perform or observe the same or any other such term, covenant or condition therein contained, and no custom or practice which may develop between the parties hereto during the term hereof shall be deemed a waiver of, or in any way affect, the right of either party to insist upon performance and observance by the other party in strict accordance with the terms hereof.

31. NOTICES All notices, demands, requests, advices or designations which may be or are required to be given by either party to the other hereunder shall be in writing. All notices, demands, requests, advices or designations by Landlord to Tenant shall be sufficiently given, made or delivered if personally served on Tenant by United States certified or registered mail, postage prepaid, or by a reputable same day or overnight courier service, addressed to Tenant at the Premises Attn: President. All notices, demands, requests, advices or designations by Tenant to Landlord shall be sent by United States certified or registered mail, postage prepaid, addressed to Landlord at its offices at Xxxxx/Xxxxxxxxx, 0000 Xxxxxxx Xxxxxxx Xxxx., Xxxxx 000, Xxxxx Xxxxx, XX 00000. Each notice, request, demand, advice or designation referred to in this paragraph shall be deemed received on the date of receipt or refusal to accept receipt of the mailing thereof in the manner herein provided, as the case may be. Either party shall have the right, upon ten (10) days written notice to the other, to change the address noted herein.

32. EXAMINATION OF LEASE Submission of this instrument for examination or signature by Tenant does not constitute a reservation of or option for a lease, and this instrument is not effective as a lease or otherwise until its execution and delivery by both Landlord and Tenant.

33. DEFAULT BY LANDLORD Landlord shall not be in default unless Landlord fails to perform obligations required of Landlord within a reasonable time, but in no event earlier than (30) days after written notice by Tenant to Landlord and to the holder of any first mortgage or deed of trust covering the Premises whose name and address shall have heretofore been furnished to Tenant in writing, specifying wherein Landlord has failed to perform such obligations; provided, however, that if the nature of Landlord's obligations is such that more than thirty (30) days are required for performance, then Landlord shall not be in default if Landlord commences performance within such thirty (30) day period and thereafter diligently prosecutes the same to completion.

34. CORPORATE AUTHORITY If Tenant is a corporation (or a partnership), each individual executing this Lease on behalf of said corporation (or partnership) represents and warrants that he is duly authorized to execute and deliver this Lease on behalf of said corporation (or partnership) in accordance with the by-laws of said corporation (or partnership in accordance with the partnership agreement) and that this Lease is binding upon said corporation (or partnership) in accordance with its terms. If Tenant is a corporation, Tenant shall, within thirty (30) days after execution of this Lease, deliver to Landlord a certified copy of the resolution of the Board of Directors of said corporation authorizing or ratifying the execution of this Lease.

40. CONSENT: Whenever the consent or approval of one party to the other is required by the terms of this Lease, such consent or approval shall not be unreasonably withheld.

41. ASSESSMENT CREDITS: The demised property herein may be subject to a special assessment levied by the City of Fremont as part of an Improvement District. As a part of said special assessment proceedings (if any), additional bonds were or may be sold and assessments were or may be levied to provide for construction contingencies and reserve funds. Interest shall be earned on such funds created for contingencies and on reserve funds which will be credited for the benefit of said assessment district. To the extent surpluses are created in said district through unused contingency funds, interest earnings or reserve funds, such surpluses shall be deemed the property of Landlord. Notwithstanding that such surpluses may be credited on assessments otherwise due against the Leased Premises, Tenant shall pay to Landlord, as additional rent if, and at the time of any such credit of surpluses, an amount equal to all such surpluses so credited. For example: if (i) the property is subject to an annual assessment of $1,000.00, and (ii) a surplus of $200.00 is credited towards the current year's assessment which reduces the assessment amount shown on the property tax xxxx from $1,000.00 to $800.00, Tenant shall, upon receipt of notice from Landlord, pay to Landlord said $200.00 credit as Additional Rent.

42. ASSIGNMENT AND SUBLETTING (CONTINUED):

A. In addition to and notwithstanding anything to the contrary in Paragraph 16 of this Lease, Landlord hereby agrees to consent to Tenant's assigning or subletting said Lease to: (i) any parent or subsidiary corporation, affiliate, or corporation with which Tenant merges or consolidates, and provided that, with respect to any such assignment, said parent or subsidiary corporation, affiliate, or said corporation has a net worth equal to or greater than the net worth of Tenant at the time of such assignment, merger, or consolidation; or (ii) any third party or entity to whom Tenant sells all or substantially all of its assets; provided, that the net worth of the resulting or acquiring corporation has a net worth after the merger, consolidation or acquisition equal to or greater than the net worth of Tenant at the time of such merger, consolidation or acquisition. No such assignment or subletting will release the Tenant from its liability and responsibility under this Lease to the extent Tenant continues in existence following such transaction. Notwithstanding the above, Tenant shall be required to (a) give Landlord written notice prior to such assignment or subletting to any party as described in (i) and (ii) above, and (b) execute Landlord's consent document prepared by Landlord reflecting the assignment or subletting.

B. Any and all sublease agreement(s) between Tenant and any and all subtenant(s) (which agreements must be consented to by Landlord, pursuant to the requirements of this Lease) shall contain the following language:

"If Landlord and Tenant jointly and voluntarily elect, for any reason whatsoever, to terminate the Master Lease prior to the scheduled Master Lease termination date, then this Sublease (if

then still in effect) shall terminate concurrently with the termination of the Master Lease. Subtenant expressly acknowledges and agrees that (1) the voluntary termination of the Master Lease by Landlord and Tenant and the resulting termination of this Sublease shall not give Subtenant any right or power to make any legal or equitable claim against Landlord, including without limitation any claim for interference with contract or interference with prospective economic advantage, and (2) Subtenant hereby waives any and all rights it may have under law or at equity against Landlord to challenge such an early termination of the Sublease, and unconditionally releases and relieves Landlord, and its officers, directors, employees and agents, from any and all claims, demands, and/or causes of action whatsoever (collectively, "Claims"), whether such matters are known or unknown, latent or apparent, suspected or unsuspected, foreseeable or unforeseeable, which Subtenant may have arising out of or in connection with any such early termination of this Sublease. Subtenant knowingly and intentionally waives any and all protection which is or may be given by Section 1542 of the California Civil Code which provides as follows: "A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with debtor.

The term of this Sublease is therefore subject to early termination. Subtenant's initials here below evidence (a) Subtenant's consideration of and agreement to this early termination provision, (b) Subtenant's acknowledgment that in determining the net benefits to be derived by Subtenant under the terms of this Sublease, Subtenant has anticipated the potential for early termination, and (c) Subtenant's agreement to the general waiver and release of Claims above.

43. HAZARDOUS MATERIALS: Landlord and Tenant agree as follows with respect to the existence or use of "Hazardous Materials" (as defined herein) on, in, under or about the Premises and real property located beneath said Premises (hereinafter collectively referred to as the "Property"):

As used herein, the term "Hazardous Materials" shall mean any hazardous or toxic substance, material or waste which is or becomes subject to or regulated by any local governmental authority, the State of California, or the United States Government. The term "Hazardous Materials" includes, without limitation any material or hazardous substance which is (i) listed under Article 9 or defined as "hazardous" or "extremely hazardous" pursuant to Article 11 of Title 22 of the California Administrative Code, Division 4, Chapter 30, (ii) listed or defined as a "hazardous waste" pursuant to the Federal Resource Conservation and Recovery Act, Section 42 U.S.C. Section 6901 et. seq., (iii) listed or defined as a "hazardous substance" pursuant to the Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. Section 9601 et. seq, (42 U.S.C. Section 9601), (iv) petroleum or any derivative of petroleum, or (v) asbestos.

Tenant shall have no obligation to "clean up", reimburse, release, indemnify, or defend Landlord with respect to any Hazardous Materials or wastes which Tenant (prior to and during the Term of the Lease) or other parties on the Property, as described below, (during the Term of this Lease) did not store, dispose, or transport in, use, or cause to be on the Property or which Tenant, its agents, employees, contractors, vendors, invitees, visitors or its future subtenants and/or assignees (if any) (during the Term of this Lease), did not store, dispose, or transport in, use or cause to be on the Property in violation of applicable law.

Tenant shall be 100 percent liable and responsible for: (i) any and all "investigation and cleanup" of any Hazardous Materials contamination resulting from any Hazardous Materials which Tenant, its agents, employees, contractors, vendors, invitees visitors or its future subtenants and/or assignees (if any), or other parties on the Property, does store, dispose, or transport in, use or cause to be on the

Property, and (ii) any claims, including third party claims, resulting from such Hazardous Materials contamination. Tenant shall indemnify Landlord and hold Landlord harmless from any liabilities, demands, costs, expenses and damages, including, without limitation, attorney fees incurred as a result of any claims resulting from any such Hazardous Materials contamination.

Tenant also agrees not to use or dispose of any Hazardous Materials on the Property without first obtaining Landlord's written consent; provided, however, that Landlord's consent shall not be required for normal use of customary household and office supplies, such as cleaners, lubricants, solvents, copier toner, etc. Tenant agrees to complete compliance with governmental regulations regarding the use or removal or remediation of all Hazardous Materials used, stored, disposed of, transported or caused to be on the Property as stated above, and prior to the termination of said Lease Tenant agrees to follow the proper closure procedures and will obtain a clearance from the local fire department and/or the appropriate governing agency. If Tenant uses any Hazardous Materials, Tenant also agrees to install, at Tenant's expense, such Hazardous Materials monitoring devices as Landlord deems reasonably necessary. It is agreed that the Tenant's responsibilities related to Hazardous Materials will survive the termination date of the Lease and that Landlord may obtain specific performance of Tenant's responsibilities under this Paragraph 43.

Subject to the terms and conditions of this Lease, Landlord hereby acknowledges its consent to Tenant's storage and use on the Property of those Hazardous Materials listed on Exhibit C attached hereto. At Tenant's sole cost and expense, each year upon the anniversary of the Commencement Date of the Lease Term ("Anniversary Date"), Tenant shall hire a qualified environmental consultant, acceptable to Landlord, to evaluate whether Tenant is in compliance with all applicable Governmental Regulations pertaining to Hazardous Materials. Tenant shall submit to Landlord a report from such environmental consultant which discusses the environmental consultant's findings within two (2) months of each Anniversary Date. Tenant shall promptly take all steps necessary to correct any and all problems identified by the environmental consultant and provide Landlord with documentation of all such corrections.

As evidenced by their initials set forth immediately below, Tenant acknowledges that Landlord has provided Tenant with copies of the environmental reports listed on Exhibit D ("Reports"), and Tenant acknowledges that Tenant and Tenant's experts (if any) have had ample opportunity to review such reports and that Tenant has satisfied itself as to the environmental conditions of the Property and the suitability of such conditions for Tenant's intended use of the Property. To the best of Landlord's knowledge as of the date of this Lease, except as noted in said Reports, no additional on site Hazardous Materials contamination exist on the Property; however, Landlord shall have no obligation to further investigate.

It is agreed that the Tenant's responsibilities related to Hazardous Materials will survive the expiration or termination of this Lease and that Landlord may obtain specific performance of Tenant's responsibilities under this Paragraph 43.

44. ASSOCIATION DUES: The Premises leased hereunder is part of the Ardenwood Property Owner's Association (the "Association"), and is subject to Association Dues to fund the cost of the Association's obligations and expenses as authorized under said Agreement. As of the date of this Lease, Tenant's current prorata share of the Association Dues is currently estimated at $44.52 per month and is subject to adjustment as provided for by said Association. Said Association Dues are payable to Tenant to Landlord as Additional Rent on a monthly basis throughout the Term of this Lease. Tenant understands that it will not be a direct member of the Association.

45.

46. TAXES CONTINUED: Notwithstanding anything within Paragraph 9, it is agreed that if any special assessments for capital improvements are assessed, and if Landlord has the option to either pay the entire assessment in cash or go to bond, and if Landlord elects to pay the entire assessment in cash in lieu of going to bond, the entire portion of the assessment assigned to Tenant's Leased Premises will be prorated over the same period that the assessment would have been prorated had the assessment gone to bond.

47. SUBORDINATION AND MORTGAGES CONTINUED: Landlord represents to Tenant that the Premises are not presently encumbered by a deed of trust or other security device in favor of any Lender.

48. LEASE CONTINGENT UPON LANDLORD OBTAINING TERMINATION AGREEMENT WITH CURRENT TENANT: This Lease is subject to and conditional upon Landlord obtaining from Matrix Pharmaceutical, Inc. ("Matrix"), the current tenant occupying the Premises leased hereunder, a Termination Agreement related to the Premises satisfactory to Landlord on or before April 30, 2002. In the event Matrix does not fully vacate and surrender the Premises to Landlord on or before April 30, 2002, the scheduled Commencement Date herein shall automatically be amended to June 1, 2002. In the event Landlord is unable to obtain said satisfactory Termination Agreement on or before May 31, 2002, this Lease shall be automatically rescinded.

Landlord and Tenant each represent and warrant that they have not dealt with any real estate brokers, agents, or finders in connection with the original Term of this Lease, and know of no real estate broker, agent or finder who is entitled to a commission in connection with this Lease ("Lease Commission"), except Xxxx Xxxxxxx of Cresa Partners, which Lease Commission shall be paid one hundred percent (100%) by Matrix Pharmaceutical, Inc. The parties hereto acknowledge that Landlord will not pay a Lease Commission to Xxxx Xxxxxxx, Cresa Partners or any other broker related to the original Term of this Lease, or in the event this Lease is extended or the square footage leased hereunder is increased for any reason whatsoever. Landlord and Tenant each agrees to defend, protect, indemnify and hold the other party harmless from and against all claims for brokerage commissions, finder's fees, and other compensation made by any other broker, agent, or finder as consequence of Landlord's or Tenant's actions or dealings with such other broker, agent or finder.

50. CROSS DEFAULT. It is understood that Landlord and Tenant have previously entered into another lease dated July 31, 1996 for premises located at 0000 Xxxxxxxxx Xxxxxx, Xxxxxxx, Xxxxxxxxxx (the "Existing Lease"). As a material part of the consideration for the execution of this Lease by Landlord, it is agreed between Landlord and Tenant that a default under this Lease, or a default under said Existing Lease may, at the option of Landlord, be considered a default under both leases, in which event Landlord shall be entitled (but in no event required) to apply all rights and remedies of Landlord under the terms of one lease to both leases including, but not limited to, the right to terminate one or both of said leases by reason of a default under said Existing Lease or hereunder.

51. OPTION TO EXTEND LEASE FOR ONE (1) YEAR SEVEN (7) MONTHS: Landlord hereby grants to Tenant an Option to Extend this Lease Agreement for an additional one (1) year seven (7) month period upon the following terms and conditions;

A. Tenant shall give Landlord written notice of Tenant's exercise of this Option to Extend not later than twelve (12) months prior to the scheduled Lease Termination Date, which Termination Date is currently projected to be June 30, 2014, in which event the Lease shall be considered extended for an additional one (1) year and seven (7) months, subject to the Basic Rental set forth below and with: (i) the Rent to be determined pursuant to Paragraph B below; (ii) the terms and conditions subject to amendment by Landlord (Landlord, in its sole and absolute discretion, may, but is not required to, incorporate its current Lease provisions that are standard in Landlord's leases as of the date of Tenant's exercise of its Option to Extend); and (iii) this Paragraph 51 deleted. In the event that Tenant fails to timely exercise Tenant's Option to Extend as set forth herein in writing, Tenant shall have no

further Option to Extend this Lease, and this Lease shall continue in full force and effect for the full remaining term hereof, absent this Paragraph 51.

B. In the event Tenant timely exercises Tenant's Option to Extend as set forth herein, Landlord shall, within fifteen (15) days after receipt of Tenant's exercise of option, advise Tenant of the terms and conditions and Rent required for the Extended Term of the Lease. Tenant shall have five (5) days after receipt from the Landlord of said new terms and conditions and Rent in which to accept said new Basic Rental, terms and conditions and enter into written documentation confirming same. In the event Tenant fails to execute said written documentation confirming said new terms and conditions and Rent for the Extended Term of Lease within said five (5) day period, Tenant shall have no further Option to Extend this Lease, and this Lease shall continue in full force and effect for the full remaining term hereof absent of this Paragraph 51, with Landlord having no further responsibility or obligation to Tenant with respect to Tenant's Option to Extend.

C. The option rights of Tenant under this Paragraph 51, and the Extended Term hereunder, are granted for Tenant's personal benefit and may not be assigned or transferred by Tenant, either voluntarily or by operation of law, in any manner whatsoever (except to a parent or subsidiary corporation or successor by merger as provided for in Paragraph 42A). In the event that Landlord consents to a sublease or assignment under Paragraph 51, the option granted herein and any Extended Term hereunder shall be void and of no force and effect, whether or not Tenant shall have purported to exercise such option prior to such assignment or sublease.

D. It is agreed that if Tenant is at any time prior to exercising its Option to Extend in default of this Lease and has failed to cure the default in the time period allowed, this Paragraph 51 will be null and void and Tenant will have no further rights under this Paragraph 51. It is further agreed that if Tenant has exercised its Option to Extend and is subsequently in default and fails to cure said default in the time period allowed prior to, or at any time the lease commences on the Extended Term, Landlord may at its sole and absolute discretion, cancel Tenant's Option to Extend, and this Lease will continue in full force and effect for the full remaining term hereof, absent of this Paragraph 51.

52.
