Immediately prior to the expiration or upon the\nsooner termination of this Lease, Tenant shall remove all of Tenant's signs from\nthe exterior of the Building and shall remove all of Tenant's equipment, trade\nfixtures, furniture, supplies, wall decorations and other personal property from\nwithin the Leased Premises, the Building and the Outside Areas, and shall vacate\nand surrender the Leased Premises, the Building, the Outside Areas and the\nProperty to Landlord in the same condition, broom clean, as existed at the Lease\nCommencement Date, reasonable wear and tear excepted. Tenant shall repair all\ndamage to the Leased Premises, the exterior of the Building and the Outside\nAreas caused by Tenant's removal of Tenant's property. Tenant shall patch and\nrefinish, to Landlord's reasonable satisfaction, all penetrations made by Tenant\nor its employees to the floor, walls or ceiling of the Leased Premises, whether\nsuch penetrations were made with Landlord's approval or not. Tenant shall repair\nall damage caused by Tenant to the exterior surface of the Building and the\npaved surfaces of the Outside Areas and, where necessary, replace or resurface\nsame. Additionally, to the extent that Landlord shall have notified or is deemed\nto have notified Tenant in writing at the time the improvements were completed\nthat it desired to have certain improvements made by Tenant or at the request of\nTenant removed at the expiration or sooner termination of the Lease, Tenant\nshall, upon the expiration or sooner termination of the Lease, remove any such\nimprovements constructed or installed by Landlord or Tenant and repair all\ndamage caused by such removal. If the Leased Premises, the Building, the Outside\nAreas and the Property are not surrendered to Landlord in the condition required\nby this paragraph at the expiration or sooner termination of this Lease,\nLandlord may, at Tenant's expense, so remove Tenant's signs, property and\/or\nimprovements not so removed and make such repairs and replacements not so made\nor hire, at Tenant's expense, independent contractors to perform such work.\nTenant shall be liable to Landlord for all costs incurred by Landlord in\nreturning the Leased Premises, the Building and the Outside Areas to the\nrequired condition, together with interest on all costs so incurred from the\ndate paid by Landlord at the then maximum rate of interest not prohibited or\nmade usurious by law until paid. Tenant shall pay to Landlord the amount of all\ncosts so incurred plus such interest thereon, within ten (10) days of Landlord's\nbilling Tenant for same. Tenant shall indemnify Landlord against loss or\nliability resulting from delay by Tenant in surrendering the Leased Premises,\nincluding, without limitation, any claims made by any succeeding Tenant or any\nlosses to Landlord with respect to lost opportunities to lease to succeeding\ntenants.\n\n\n                                    ARTICLE 3\n\n                    RENT, LATE CHARGES AND SECURITY DEPOSITS\n\n3.1 BASE MONTHLY RENT.

Payment shall be made by whichever of the\nfollowing methods (or combination of methods) is (are) from time to time\ndesignated by Landlord:\n\n               (i) Landlord may forward invoices or bills for such expenses to\nTenant, and Tenant shall, no later than ten (10) days prior to the due date, pay\nsuch invoices or bills and deliver satisfactory evidence of such payment to\nLandlord, and\/or\n\n               (ii) Landlord may bill to Tenant, on a periodic basis not more\nfrequently than monthly, the amount of such expenses (or group of expenses) as\npaid or incurred by Landlord, and Tenant shall pay to Landlord the amount of\nsuch expenses within ten days after receipt of a written bill therefor from\nLandlord, and\/or\n\n               (iii) Landlord may deliver to Tenant Landlord's reasonable\nestimate of any given expense (such as Landlord's Insurance Costs or Real\nProperty Taxes), or group of expenses, which it anticipates will be paid or\nincurred for the ensuing calendar or fiscal year, as Landlord may determine, and\nTenant shall pay to Landlord an amount equal to the estimated amount of such\nexpenses for such year in equal monthly installments during such year with the\ninstallments of Base Monthly Rent.\n\nLandlord reserves the right to change from time to time the methods of billing\nTenant for any given expense or group of expenses or the periodic basis on which\nsuch expenses are billed.\n\n        (b) Landlord's share of the consideration received by Tenant upon\ncertain assignments and sublettings as required by Article 7.\n\n        (c) Any legal fees and costs that Tenant is obligated to pay or\nreimburse to Landlord pursuant to Article 13; and\n\n        (d) Any other charges or reimbursements due Landlord from Tenant\npursuant to the terms of this Lease.\n\nNotwithstanding the foregoing, Landlord may elect by written notice to Tenant to\nhave Tenant pay Real Property Taxes or any portion thereof directly to the\napplicable taxing authority, in which case Tenant shall make such payments and\ndeliver satisfactory evidence of payment to Landlord no later than ten (10) days\nbefore such Real Property Taxes become delinquent.\n\n3.3 YEAR-END ADJUSTMENTS. If Landlord shall have elected to bill Tenant for the\nProperty Operating Expenses (or any group of such expenses) on an estimated\nbasis in accordance with the provisions of Paragraph 3.2(a)(iii) above, Landlord\nshall furnish to Tenant within three months following the end of the applicable\ncalendar or fiscal year, as the case may be, a statement setting forth (i) the\namount of such expenses paid or incurred during the just ended calendar or\nfiscal year, as appropriate, and (ii) the amount that Tenant has paid to\nLandlord for credit against such expenses for such period. If Tenant shall have\npaid more than its obligation for such expenses for the stated period, Landlord\nshall, at its election, either (i) credit the amount of such overpayment toward\nthe next ensuing payment or payments of Additional Rent that would otherwise be\ndue or (ii) refund in cash to Tenant the amount of such overpayment. If such\nyear-end statement shall show that Tenant did not pay its obligation for such\nexpenses in full, then Tenant shall pay to Landlord the amount of such\nunderpayment within ten days from Landlord's billing of same to Tenant. The\nprovisions of this Paragraph shall survive the expiration or sooner termination\nof this Lease.\n\n3.4 LATE CHARGE, AND INTEREST ON RENT IN DEFAULT. Tenant acknowledges that the\nlate payment by Tenant of any monthly installment of Base Monthly Rent or any\nAdditional Rent will cause Landlord to incur certain costs and expenses not\ncontemplated under this Lease, the exact amounts of which are extremely\ndifficult or impractical to fix. Such costs and expenses will include without\nlimitation, administration and collection costs and processing and accounting\nexpenses. Therefor, if any installment of Base Monthly Rent is not received by\nLandlord from Tenant within five (5) calendar days after the same becomes due,\nTenant shall immediately pay to Landlord a late charge in an amount equal to the\namount set forth in Article 1 as the \"Late Charge Amount,\" and if any Additional\nRent is not received by Landlord when the same becomes due, Tenant shall\nimmediately pay to Landlord a late charge in an amount equal to 5% of the\nAdditional Rent not so paid. Landlord and Tenant agree that this late charge\nrepresents a reasonable estimate of such costs and expenses and is fair\ncompensation to Landlord for the anticipated loss Landlord would suffer by\nreason of Tenant's failure to make timely payment. In no event shall this\nprovision for a late charge be deemed to grant to Tenant a grace period or\nextension of time within which to pay any rental installment or prevent Landlord\nfrom exercising any right or remedy available to Landlord upon Tenant's failure\nto pay each rental installment due under this Lease when due, including the\nright to terminate this Lease. If any rent remains delinquent for a period in\nexcess of five (5) calendar days, then, in addition to such late charge, Tenant\nshall pay to Landlord interest on any rent that is not so paid from said tenth\nday at the then maximum rate of interest not prohibited or made usurious by Law\nuntil paid.\n\n3.5 PAYMENT OF RENT. Except as specifically provided otherwise in this Lease,\nall rent shall be paid in lawful money of the United States, without any\nabatement, reduction or offset for any reason whatsoever, to Landlord at such\naddress as Landlord may designate from time to time. Tenant's obligation to pay\nBase Monthly Rent and all Additional Rent shall be appropriately prorated at the\ncommencement and expiration of the Lease Term.

The acceptance of rent by Landlord from\nany person or entity other than Tenant, or the acceptance of rent by Landlord\nfrom Tenant with knowledge of a violation of the provisions of this paragraph,\nshall not be deemed to be a waiver by Landlord of any provision of this Article\nor this Lease or to be a consent to any subletting by Tenant or any assignment\nof Tenant's interest in this Lease.

Any dissolution, merger,\nconsolidation or other reorganization of Tenant, or the sale or other transfer\nin the aggregate over the Lease Term of a controlling percentage of the capital\nstock of Tenant, or the sale or transfer of all or a substantial portion of the\nassets of Tenant, shall be deemed a voluntary assignment of Tenant's interest in\nthis Lease. The phrase \"controlling percentage\" means the ownership of and the\nright to vote stock possessing more than fifty percent of the total combined\nvoting power of all classes of Tenant's capital stock issued, outstanding and\nentitled to vote for the election of directors. If Tenant is a partnership, a\nwithdrawal or change, voluntary, involuntary or by operation of Law, of any\ngeneral partner, or the dissolution of the partnership, shall be deemed a\nvoluntary assignment of Tenant's interest in this Lease. Upon Landlord's request\nfrom time to time, Tenant shall promptly provide Landlord with a statement\ncertified by the Tenant's chief operating officer, which shall provide the\nfollowing information: (a) the names of all of Tenant's shareholders and their\nownership interests at the time thereof, provided Tenant's shares are not\npublicly traded; (b) the state in which Tenant is incorporated; (c) the location\nof Tenant's principal place of business; (d) information regarding a material\nchange in the corporate structure of Tenant, including, without limitation, a\nmerger or consolidation; and (e) any other information regarding Tenant's\nownership that Landlord reasonably requests.

Such damages shall include, without limitation:\n\n               (i) The worth at the time of the award of the unpaid rent which\nhad been earned at the time of termination;\n\n               (ii) The worth at the time of award of the amount by which the\nunpaid rent for the balance of the term after the time of award exceeds the\namount of such rental loss that Tenant proves could be reasonably avoided,\ncomputed by discounting such amount at the discount rate of the Federal Reserve\nBank of San Francisco, at the time of award plus one percent; and\n\n               (iii) Any other amount necessary to compensate Landlord for all\ndetriment proximately caused by Tenant's failure to perform Tenant's obligations\nunder this Lease, or which in the ordinary course of things would be likely to\nresult therefrom, including without limitation, the following: (i) expenses for\ncleaning, repairing or restoring the Leased Premises, (ii) expenses for\naltering, remodeling or otherwise improving the Leased Premises for the purpose\nof reletting, including removal of existing leasehold improvements and\/or\ninstallation of additional leasehold improvements (regardless of how the same is\nfunded, including reduction of rent, a direct payment or allowance to a new\ntenant, or otherwise), (iii) broker's fees allocable to the remainder of the\nterm of this Lease, advertising costs and other expenses of reletting the Leased\nPremises; (iv) costs of carrying and maintaining the Leased Premises, such as\ntaxes, insurance premiums, utility charges and security precautions, (v)\nexpenses incurred in removing, disposing of and\/or storing any of Tenant's\npersonal property, inventory or trade fixtures remaining therein; (vi)\nreasonable attorney's fees, expert witness fees, court costs and other\nreasonable expenses incurred by Landlord (but not limited to taxable costs) in\nretaking possession of the Leased Premises, establishing damages hereunder, and\nreleasing the Leased Premises; and (vii) any other expenses, costs or damages\notherwise incurred or suffered as a result of Tenant's default.\n\n12.3 LANDLORD'S DEFAULT AND TENANT'S REMEDIES. In the event Landlord fails to\nperform its obligations under this Lease, Landlord shall nevertheless not be in\ndefault under the terms of this Lease until such time as Tenant shall have first\ngiven Landlord written notice specifying the nature of such failure to perform\nits obligations, and then only after Landlord shall have had thirty (30) days\nfollowing its receipt of such notice within which to perform such obligations;\nprovided that, if longer than thirty (30) days is reasonably required in order\nto perform such obligations, Landlord shall have such longer period. In the\nevent of Landlord's default as above set forth, then, and only then, Tenant may\nthen proceed in equity or at law to compel Landlord to perform its obligations\nand\/or to recover damages proximately caused by such failure to perform (except\nas and to the extent Tenant has waived its right to damages as provided in this\nLease).\n\n12.4 LIMITATION OF TENANT'S RECOURSE. If Landlord is a corporation, trust,\npartnership, joint venture, limited liability company, unincorporated\nassociation, or other form of business entity, Tenant agrees that (i) the\nobligations of Landlord under this Lease shall not constitute personal\nobligations of the officers, directors, trustees, partners,\n\n\n\n                                      18.\n   20\n\njoint venturers, members, owners, stockholders, or other principals of such\nbusiness entity, and (ii) Tenant shall have recourse only to the property of\nsuch corporation, trust, partnership, joint venture, limited liability company,\nunincorporated association, or other form of business entity for the\nsatisfaction of such obligations and not against the assets of such officers,\ndirectors, trustees, partners, joint venturers, members, owners, stockholders or\nprincipals.

Landlord and Tenant agree that the provisions of Paragraph\n12.3 above are intended to supersede and replace the provisions of California\nCivil Code Sections 1932(1), 1941 and 1942, and accordingly, Tenant hereby\nwaives the provisions of California Civil Code Sections 1932(1), 1941 and 1942\nand\/or any similar or successor law regarding Tenant's right to terminate this\nLease or to make repairs and deduct the expenses of such repairs from the rent\ndue under this Lease.\n\n\n                                   ARTICLE 13\n\n                               GENERAL PROVISIONS\n\n13.1 TAXES ON TENANT'S PROPERTY. Tenant shall pay before delinquency any and all\ntaxes, assessments, license fees, use fees, permit fees and public charges of\nwhatever nature or description levied, assessed or imposed against Tenant or\nLandlord by a governmental agency arising out of, caused by reason of or based\nupon Tenant's estate in this Lease, Tenant's ownership of property, improvements\nmade by Tenant to the Leased Premises or the Outside Areas, improvements made by\nLandlord for Tenant's use within the Leased Premises or the Outside Areas,\nTenant's use (or estimated use) of public facilities or services or Tenant's\nconsumption (or estimated consumption) of public utilities, energy, water or\nother resources (collectively, \"Tenant's Interest\"). Upon demand by Landlord,\nTenant shall furnish Landlord with satisfactory evidence of these payments.\nTenant may elect to protest such taxes provided that Tenant first notifies\nLandlord in writing and posts a bond equal to 100% of the maximum amount of such\ntaxes plus penalties and interest. If any such taxes, assessments, fees or\npublic charges are levied against Landlord, Landlord's property, the Building or\nthe Property, or if the assessed value of the Building or the Property is\nincreased by the inclusion therein of a value placed upon Tenant's Interest,\nregardless of the validity thereof, Landlord shall have the right to require\nTenant to pay such taxes, and if not paid and satisfactory evidence of payment\ndelivered to Landlord at least ten days prior to delinquency, then Landlord\nshall have the right to pay such taxes on Tenant's behalf and to invoice Tenant\nfor the same. Tenant shall, within the earlier to occur of (a) thirty (30) days\nof the date it receives an invoice from Landlord setting forth the amount of\nsuch taxes, assessments, fees, or public charge so levied, or (b) the due date\nof such invoice, pay to Landlord, as Additional Rent, the amount set forth in\nsuch invoice. Failure by Tenant to pay the amount so invoiced within such time\nperiod shall be conclusively deemed a default by Tenant under this Lease. Tenant\nshall have the right to bring suit in any court of competent jurisdiction to\nrecover from the taxing authority the amount of any such taxes, assessments,\nfees or public charges so paid.\n\n13.2 HOLDING OVER. This Lease shall terminate without further notice on the\nLease Expiration Date (as set forth in Article 1). Any holding over by Tenant\nafter expiration of the Lease Term shall neither constitute a renewal nor\nextension of this Lease nor give Tenant any rights in or to the Leased Premises\nexcept as expressly provided in this Paragraph. Any such holding over to which\nLandlord has consented shall be construed to be a tenancy from month to month,\non the same terms and conditions herein specified insofar as applicable, except\nthat the Base Monthly Rent shall be increased to an amount equal to one hundred\nfifty percent (150%) of the Base Monthly Rent payable during the last full month\nimmediately preceding such holding over. Tenant acknowledges that if Tenant\nholds over without Landlord's consent, such holding over may compromise or\notherwise affect Landlord's ability to enter into new leases with prospective\ntenants regarding the Leased Premises. Therefore, if Tenant fails to surrender\nthe Leased Premises upon the expiration or termination of this Lease, in\naddition to any other liabilities to Landlord accruing therefrom, Tenant shall\nprotect, defend, indemnify and hold Landlord harmless from and against all\nclaims resulting from such failure, including, without limiting the foregoing,\nany claims made by any succeeding tenant founded upon such failure to surrender,\nand any losses suffered by Landlord, including lost profits, resulting from such\nfailure to surrender.\n\n13.3 SUBORDINATION TO MORTGAGES. This Lease is subject to and subordinate to all\nground leases, mortgages and deeds of trust which affect the Building or the\nProperty and which are of public record as of the Effective Date of this Lease,\nand to all renewals, modifications, consolidations, replacements and extensions\nthereof. However, if the lessor under any such ground lease or any lender\nholding any such mortgage or deed of trust shall advise Landlord that it desires\nor requires this Lease to be made prior and superior thereto, then, upon written\nrequest of Landlord to\n\n\n\n                                      19.\n   21\n\nTenant, Tenant shall promptly execute, acknowledge and deliver any and all\ncustomary or reasonable documents or instruments which Landlord and such lessor\nor lender deems necessary or desirable to make this Lease prior thereto. Tenant\nhereby consents to Landlord's ground leasing the land underlying the Building or\nthe Property and\/or encumbering the Building or the Property as security for\nfuture loans on such terms as Landlord shall desire, all of which future ground\nleases, mortgages or deeds of trust shall be subject to and subordinate to this\nLease. However, if any lessor under any such future ground lease or any lender\nholding such future mortgage or deed of trust shall desire or require that this\nLease be made subject to and subordinate to such future ground lease, mortgage\nor deed of trust, then Tenant agrees, within ten days after Landlord's written\nrequest therefor, to execute, acknowledge and deliver to Landlord any and all\ndocuments or instruments requested by Landlord or by such lessor or lender as\nmay be necessary or proper to assure the subordination of this Lease to such\nfuture ground lease, mortgage or deed of trust, but only if such lessor or\nlender agrees to recognize Tenant's rights under this Lease and agrees not to\ndisturb Tenant's quiet possession of the Leased Premises so long as Tenant is\nnot in default under this Lease. If Landlord assigns the Lease as security for a\nloan, Tenant agrees to execute such documents as are reasonably requested by the\nlender and to provide reasonable provisions in the Lease protecting such\nlender's security interest which are customarily required by institutional\nlenders making loans secured by a deed of trust. Landlord agrees to use\ncommercially reasonable efforts to obtain a subordination, non-disturbance\nagreement and attornment agreement from the existing lender holding a deed of\ntrust on the Property.\n\n13.4 TENANT'S ATTORNMENT UPON FORECLOSURE. Tenant shall, upon request, attorn\n(i) to any purchaser of the Building or the Property at any foreclosure sale or\nprivate sale conducted pursuant to any security instruments encumbering the\nBuilding or the Property, (ii) to any grantee or transferee designated in any\ndeed given in lieu of foreclosure of any security interest encumbering the\nBuilding or the Property, or (iii) to the lessor under an underlying ground\nlease of the land underlying the Building or the Property, should such ground\nlease be terminated; provided that such purchaser, grantee or lessor recognizes\nTenant's rights under this Lease.\n\n13.5 MORTGAGEE PROTECTION. In the event of any default on the part of Landlord,\nTenant will give notice by registered mail to any Lender or lessor under any\nunderlying ground lease who shall have requested, in writing, to Tenant that it\nbe provided with such notice, and Tenant shall offer such Lender or lessor a\nreasonable opportunity to cure the default, including time to obtain possession\nof the Leased Premises by power of sale or judicial foreclosure or other\nappropriate legal proceedings if reasonably necessary to effect a cure.\n\n13.6 ESTOPPEL CERTIFICATE. Tenant will, following any request by Landlord,\npromptly execute and deliver to Landlord an estoppel certificate substantially\nin form attached as Exhibit E, and certifying such other information about this\nLease, if true, as may be reasonably requested by Landlord, its Lender or\nprospective lenders, investors or purchasers of the Building or the Property.\nTenant's failure to execute and deliver such estoppel certificate within ten\n(10) days after Landlord's request therefor shall be a material default by\nTenant under this Lease, and Landlord shall have all of the rights and remedies\navailable to Landlord as Landlord would otherwise have in the case of any other\nmaterial default by Tenant, including the right to terminate this Lease and sue\nfor damages proximately caused thereby, it being agreed and understood by Tenant\nthat Tenant's failure to so deliver such estoppel certificate in a timely manner\ncould result in Landlord being unable to perform committed obligations to other\nthird parties which were made by Landlord in reliance upon this covenant of\nTenant. Landlord and Tenant intend that any statement delivered pursuant to this\nparagraph may be relied upon by any Lender or purchaser or prospective Lender or\npurchaser of the Building, the Property, or any interest in them.\n\n13.7 TENANT'S FINANCIAL INFORMATION. Tenant shall, within ten business days\nafter Landlord's request therefor, deliver to Landlord a copy of Tenant's (and\nany guarantor's) current financial statements (including a balance sheet, income\nstatement and statement of cash flow, all prepared in accordance with generally\naccepted accounting principles) and any such other information reasonably\nrequested by Landlord regarding Tenant's financial condition. Landlord shall be\nentitled to disclose such financial statements or other information to its\nLender, to any present or prospective principal of or investor in Landlord, or\nto any prospective Lender or purchaser of the Building, the Property, or any\nportion thereof or interest therein. Any such financial statement or other\ninformation which is marked \"confidential\" or \"company secrets\" (or is otherwise\nsimilarly marked by Tenant) shall be confidential and shall not be disclosed by\nLandlord to any third party except as specifically provided in this paragraph,\nunless the same becomes a part of the public domain without the fault of\nLandlord.\n\n13.8 TRANSFER BY LANDLORD. Landlord and its successors in interest shall have\nthe right to transfer their interest in the Building, the Property, or any\nportion thereof at any time and to any person or entity. In the event of any\nsuch transfer, the Landlord originally named herein (and in the case of any\nsubsequent transfer, the transferor), from the date of such transfer, (i) shall\nbe automatically relieved, without any further act by any person or entity, of\nall liability for the performance of the obligations of the Landlord hereunder\nwhich may accrue after the date of such transfer and (ii) shall be relieved of\nall liability for the performance of the obligations of the Landlord hereunder\nwhich have accrued before the date of transfer if its transferee agrees to\nassume and perform all such prior obligations of the Landlord hereunder. Tenant\nshall attorn to any such transferee. After the date of any such transfer, the\nterm \"Landlord\" as used herein shall mean the transferee of such interest in the\nBuilding or the Property.\n\n13.9 FORCE MAJEURE. The obligations of each of the parties under this Lease\n(other than the obligations to pay money) shall be temporarily excused if such\nparty is prevented or delayed in performing such obligations by reason of any\nstrikes, lockouts or labor disputes; government restrictions, regulations,\ncontrols, action or inaction; civil commotion; or extraordinary weather, fire or\nother acts of God.\n\n13.10 NOTICES.

No subsequent changes,\nmodifications or additions to this Lease shall be binding upon the parties\nunless in writing and signed by both Landlord and Tenant.\n\n14.4 LANDLORD'S REPRESENTATIONS. Tenant acknowledges that neither Landlord nor\nany of its agents made any representations or warranties respecting the\nProperty, the Building or the Leased Premises, upon which Tenant relied in\nentering into the Lease, which are not expressly set forth in this Lease. Tenant\nfurther acknowledges that neither Landlord nor any of its agents made any\nrepresentations as to (i) whether the Leased Premises may be used for Tenant's\nintended use under existing Law, or (ii) the suitability of the Leased Premises\nfor the conduct of Tenant's business, or (iii) the exact square footage of the\nLeased Premises, and that Tenant relies solely upon its own investigations with\nrespect to such matters. Tenant expressly waives any and all claims for damage\nby reason of any statement, representation, warranty, promise or other agreement\nof Landlord or Landlord's agent(s), if any, not contained in this Lease or in\nany Exhibit attached hereto.\n\n\n                                   ARTICLE 15\n\n                                OPTIONS TO EXTEND\n\n15.1 So long as Redback Networks, Inc. is the Tenant hereunder and occupies the\nentirety of the Leased Premises, and subject to the condition set forth in\nclause (b) below, Tenant shall have two options to extend the term of this Lease\nwith respect to the entirety of the Leased Premises, the first for a period of\nfive (5) years from the expiration of the ninth year of the Lease Term (the\n\"First Extension Period\"), and the second (the \"Second Extension Period\") for a\nperiod of five (5) years from the expiration of the First Extension Period,\nsubject to the following conditions:\n\n        (a) Each option to extend shall be exercised, if at all, by notice of\nexercise given to Landlord by Tenant not more than twelve (12) months nor less\nthan nine (9) months prior to the expiration of the ninth year of the Lease Term\nor the expiration of the First Extension Period, as applicable;\n\n        (b) Anything herein to the contrary notwithstanding, if Tenant is in\ndefault under any of the terms, covenants or conditions of this Lease, either at\nthe time Tenant exercises either extension option or on the commencement date of\nthe First Extension Period or the Second Extension Period, as applicable,\nLandlord shall have, in addition to all of Landlord's other rights and remedies\nprovided in this Lease, the right to terminate such option(s) to extend upon\nnotice to Tenant.\n\n15.2 In the event the applicable option is exercised in a timely fashion, the\nLease shall be extended for the term of the applicable extension period upon all\nof the terms and conditions of this Lease, provided that the Base Monthly Rent\nfor each extension period shall be ninety-five percent (95%) of the \"Fair Market\nRent\" for the Leased Premises, increased as set forth below. For purposes\nhereof, \"Fair Market Rent\" shall mean the Base Monthly Rent determined pursuant\nto the process described below. In no event, however, shall any adjustment of\nBase Monthly Rent pursuant to this paragraph result in a decrease of the Base\nMonthly Rent for the Leased Premises below the amount due from Tenant for the\npreceding portion of the initial Lease Term (or the First Extension Period, if\nsuch Base Monthly Rent is being determined for the Second Extension Period) for\nwhich Base Monthly Rent had been fixed.\n\n\n\n                                      23.\n   25\n\n15.3 Within thirty (30) days after receipt of Tenant's notice of exercise,\nLandlord shall notify Tenant in writing of Landlord's estimate of the Base\nMonthly Rent for the first year of the applicable extension period, and\nLandlord's estimate of annual increases. For purposes hereof, \"Fair Market Rent\"\nshall mean collectively, (1) Base Monthly Rent for the first year of the\napplicable extension period and (2) annual increases, if any, determined at the\ntime and in the same manner Base Monthly Rent for the first year is determined.\nWithin 30 days after receipt of such notice from Landlord, Tenant shall have the\nright either to (i) accept Landlord's estimate of Fair Market Rent or (ii) elect\nto arbitrate Landlord's estimate of Fair Market Rent, such arbitration to be\nconducted pursuant to the provisions hereof. Failure on the part of Tenant to\nrequire arbitration of Fair Market Rent within such 30-day period shall\nconstitute acceptance of the Fair Market Rent for the applicable extension\nperiod as calculated by Landlord. If Tenant elects arbitration, the arbitration\nshall be concluded within 90 days after the date of Tenant's election, subject\nto extension for an additional 30-day period if a third arbitrator is required\nand does not act in a timely manner. To the extent that arbitration has not been\ncompleted prior to the expiration of any preceding period for which Base Monthly\nRent has been determined, Tenant shall pay Base Monthly Rent at the rate\ncalculated by Landlord, with the potential for an adjustment to be made once\nFair Market Rent is ultimately determined by arbitration.\n\n15.4 In the event of arbitration, the judgment or the award rendered in any such\narbitration may be entered in any court having jurisdiction and shall be final\nand binding between the parties. The arbitration shall be conducted and\ndetermined in the City and County of San Francisco in accordance with the then\nprevailing rules of the American Arbitration Association or its successor for\narbitration of commercial disputes except to the extent that the procedures\nmandated by such rules shall be modified as follows:\n\n        (a) Tenant shall make demand for arbitration in writing within thirty\n(30) days after service of Landlord's determination of Fair Market Rent given\nunder Paragraph 15.3 above, specifying therein the name and address of the\nperson to act as the arbitrator on its behalf. The arbitrator shall be qualified\nas a real estate appraiser familiar with the Fair Market Rent of similar\nindustrial, research and development, or office space in the Silicon Valley area\nwho would qualify as an expert witness over objection to give opinion testimony\naddressed to the issue in a court of competent jurisdiction. Failure on the part\nof Tenant to make a proper demand in a timely manner for such arbitration shall\nconstitute a waiver of the right thereto. Within fifteen (15) days after the\nservice of the demand for arbitration, Landlord shall give notice to Tenant,\nspecifying the name and address of the person designated by Landlord to act as\narbitrator on its behalf who shall be similarly qualified. If Landlord fails to\nnotify Tenant of the appointment of its arbitrator, within or by the time above\nspecified, then the arbitrator appointed by Tenant shall be the arbitrator to\ndetermine the issue.\n\n        (b) In the event that two arbitrators are chosen pursuant to Paragraph\n15.4(a) above, the arbitrators so chosen shall, within fifteen (15) days after\nthe second arbitrator is appointed determine the Fair Market Rent. If the two\narbitrators shall be unable to agree upon a determination of Fair Market Rent\nwithin such 15-day period, they, themselves, shall appoint a third arbitrator,\nwho shall be a competent and impartial person with qualifications similar to\nthose required of the first two arbitrators pursuant to Paragraph 15.4(a). In\nthe event they are unable to agree upon such appointment within seven days after\nexpiration of such 15-day period, the third arbitrator shall be selected by the\nparties themselves, if they can agree thereon, within a further period of\nfifteen (15) days. If the parties do not so agree, then either party, on behalf\nof both, may request appointment of such a qualified person by the then Chief\nJudge of the United States District Court having jurisdiction over the County of\nSanta Clara, acting in his private and not in his official capacity, and the\nother party shall not raise any question as to such Judge's full power and\njurisdiction to entertain the application for and make the appointment. The\nthree arbitrators shall decide the dispute if it has not previously been\nresolved by following the procedure set forth below.\n\n        (c) Where an issue cannot be resolved by agreement between the two\narbitrators selected by Landlord and Tenant or settlement between the parties\nduring the course of arbitration, the issue shall be resolved by the three\narbitrators within 15 days of the appointment of the third arbitrator in\naccordance with the following procedure. The arbitrator selected by each of the\nparties shall state in writing his determination of the Fair Market Rent\nsupported by the reasons therefor with counterpart copies to each party. The\narbitrators shall arrange for a simultaneous exchange of such proposed\nresolutions. The role of the third arbitrator shall be to select which of the\ntwo proposed resolutions most closely approximates his determination of Fair\nMarket Rent. The third arbitrator shall have no right to propose a middle ground\nor any modification of either of the two proposed resolutions. The resolution he\nchooses as most closely approximating his determination shall constitute the\ndecision of the arbitrators and be final and binding upon the parties.\n\n        (d) In the event of a failure, refusal or inability of any arbitrator to\nact, his successor shall be appointed by him, but in the case of the third\narbitrator, his successor shall be appointed in the same manner as provided for\nappointment of the third arbitrator. The arbitrators shall decide the issue\nwithin fifteen (15) days after the appointment of the third arbitrator. Any\ndecision in which the arbitrator appointed by Landlord and the arbitrator\nappointed by Tenant concur shall be binding and conclusive upon the parties.\nEach party shall pay the fee and expenses of its respective arbitrator and both\nshall share the fee and expenses of the third arbitrator, if any, and the\nattorneys' fees and expenses of counsel for the respective parties and of\nwitnesses shall be paid by the respective party engaging such counsel or calling\nsuch witnesses.\n\n        (e) The arbitrators shall have the right to consult experts and\ncompetent authorities to obtain factual information or evidence pertaining to a\ndetermination of Fair Market Rent, but any such consultation shall be made in\nthe presence of both parties with full right on their part to cross-examine. The\narbitrators shall render their decision and award in writing with counterpart\ncopies to each party. The arbitrators shall have no power to modify the\nprovisions of this Lease.\n\n\n\n                                      24.\n   26\n\n                                   ARTICLE 16\n\n                                TELEPHONE SERVICE\n\n        Notwithstanding any other provision of this Lease to the contrary:\n\n        (a) So long as the entirety of the Leased Premises is leased to Tenant:\n\n               (i) Landlord shall have no responsibility for providing to Tenant\nany telephone equipment, including wiring, within the Leased Premises or for\nproviding telephone service or connections from the utility to the Leased\nPremises; and\n\n               (ii) Landlord makes no warranty as to the quality, continuity or\navailability of the telecommunications services in the Building, and Tenant\nhereby waives any claim against Landlord for any actual or consequential damages\n(including damages for loss of business) in the event Tenant's\ntelecommunications services in any way are interrupted, damaged or rendered less\neffective, except to the extent caused by the grossly negligent or willful act\nor omission by Landlord, its agents or employees. Landlord shall not be liable\nto Tenant and Tenant waives all claims against Landlord whatsoever, whether for\npersonal injury, property damage, loss of use of the Leased Premises, or\notherwise, due to the interruption or failure of telephone services to the\nLeased Premises. Tenant hereby holds Landlord harmless and agrees to indemnify,\nprotect and defend Landlord from and against any liability for any damage, loss\nor expense due to any failure or interruption of telephone service to the Leased\nPremises for any reason.\n\n        (b) At such time as the entirety of the Building is no longer leased to\nTenant, Landlord shall in its sole discretion have the right, by written notice\nto Tenant, to elect to assume limited responsibility for INC, as provided below,\nand upon such assumption of responsibility by Landlord, this subparagraph (b)\nshall apply prospectively.\n\n               (i) Landlord shall provide Tenant access to such quantity of\npairs in the Building intra-building network cable (\"INC\") as is determined to\nbe available by Landlord in its reasonable discretion. Tenant's access to the\nINC shall be solely by arrangements made by Tenant, as Tenant may elect,\ndirectly with Pacific Bell or Landlord (or such vendor as Landlord may\ndesignate), and Tenant shall pay all reasonable charges as may be imposed in\nconnection therewith. Pacific Bell's charges shall be deemed to be reasonable.\nSubject to the foregoing, Landlord shall have no responsibility for providing to\nTenant any telephone equipment, including wiring, within the Leased Premises or\nfor providing telephone service or connections from the utility to the Leased\nPremises, except as required by law.\n\n               (ii) Tenant shall not alter, modify, add to or disturb any\ntelephone wiring in the Leased Premises or elsewhere in the Building without the\nLandlord's prior written consent. Tenant shall be liable to Landlord for any\ndamage to the telephone wiring in the Building due to the act, negligent or\notherwise, of Tenant or any employee, contractor or other agent of Tenant.\nTenant shall have no access to the telephone closets within the Building, except\nin the manner and under procedures established by Landlord. Tenant shall\npromptly notify Landlord of any actual or suspected failure of telephone service\nto the Leased Premises.\n\n               (iii) All costs incurred by Landlord for the installation,\nmaintenance, repair and replacement of telephone wiring in the Building shall be\na Property Maintenance Cost.\n\n               (iv) Landlord makes no warranty as to the quality, continuity or\navailability of the telecommunications services in the Building, and Tenant\nhereby waives any claim against Landlord for any actual or consequential damages\n(including damages for loss of business) in the event Tenant's\ntelecommunications services in any way are interrupted, damaged or rendered less\neffective, except to the extent caused by the grossly negligent or willful act\nor omission by Landlord, its agents or employees. Tenant acknowledges that\nLandlord meets its duty of care to Tenant with respect to the Building INC by\ncontracting with a reliable third party vendor to assume responsibility for the\nmaintenance and repair thereof (which contract shall contain provisions\nrequiring such vendor to inspect the INC periodically (the frequency of such\ninspections to be determined by such vendor based on its experience and\nprofessional judgment), and requiring such vendor to meet local and federal\nrequirements for telecommunications material and workmanship). Subject to the\nforegoing, Landlord shall not be liable to Tenant and Tenant waives all claims\nagainst Landlord whatsoever, whether for personal injury, property damage, loss\nof use of the Leased Premises, or otherwise, due to the interruption or failure\nof telephone services to the Leased Premises. Tenant hereby holds Landlord\nharmless and agrees to indemnify, protect and defend Landlord from and against\nany liability for any damage, loss or expense due to any failure or interruption\nof telephone service to the Leased Premises for any reason.\n\n\n\n                                      25.\n   27\n\n        IN WITNESS WHEREOF, Landlord and Tenant have executed this Lease as of\nthe respective dates below set forth with the intent to be legally bound thereby\nas of the Effective Date of this Lease first above set forth.\n\n\n                                    LANDLORD:\n\n                                    CORPORATE TECHNOLOGY CENTRE ASSOCIATES LLC,\n                                    a California limited liability company\n\n                                    By: Corporate Technology Centre Partners LLC\n                                        a California limited liability company\n                                        Its Manager\n\n                                        By: Menlo Equities LLC\n                                            a California limited liability\n                                            company\n                                            Its Managing Member\n\n                                            By:  Menlo Equities, Inc.\n                                                 Its Managing Member\n\nDated: October 27, 1999                         By: \/s\/ Henry D.
