If either party so elects to terminate this Lease, the Lease shall be deemed terminated as of the date the notice is given, Landlord shall return to Tenant any payments made by Tenant to Landlord hereunder, and neither party shall have further rights under this Lease nor further obligations to the other hereunder. If Landlord, for any reason other than a Tenant Delay, has not delivered vacant possession of the Premises in "Ready for Occupancy" condition within twenty-four (24) months after the date of this Lease, Tenant may terminate this Lease and Landlord shall return to Tenant any payments made by Tenant to Landlord hereunder, and neither party shall have further rights under this Lease nor further obligations to the other hereunder.

On the Commencement Date, and on the first day of each calendar month during each ensuing calendar year, Tenant shall pay in advance to Landlord Tenant's Share of one-twelfth (1/12th) of the most recent estimated Operating Expenses; provided, however, that if such notice is not given in December, Tenant shall continue to pay to Landlord Tenant's Share of one-twelfth (1/12th) of the Estimated Operating Expenses of the previous calendar year until the month after such statement is given. Within one hundred twenty (120) days after the end of each calendar year during the Term or as soon thereafter as practicable, Landlord shall furnish to Tenant a statement of the actual Operating Expenses for such calendar year. If Tenant's Share of the estimated Operating Expenses paid by Tenant during such calendar year is (x) less than Tenant's Share of the actual Operating Expenses for such period as shown on Landlord's statement, then Tenant shall pay the difference to Landlord within thirty (30) days after the date of Landlord's statement, or (y,) more than Tenant's Share of the actual Operating Expenses for such period, then Tenant shall receive a credit on the Rent next due for the amount of such excess, or, if the statement is given by Landlord with respect to the calendar year in which the Term expires, Landlord shall pay such excess to Tenant together with such statement. 5.3 ADJUSTMENTS TO OPERATING EXPENSES. If at any time, but no more than once each calendar year, it appears to Landlord that the actual Operating Expenses for any calendar year during the Term will exceed the estimated Operating Expenses set forth in Landlord's statement to Tenant by more than five percent (5%), then Landlord shall have the right by notice to Tenant to revise the estimated Operating Expenses for such year and subsequent payments thereof shall, commencing with the first month after which Tenant receives such notice, be increased based upon such revised statement. 7 5.4 TENANT'S INSPECTION AND AUDIT RIGHTS.

If Tenant has an audit performed of such books and records by a certified public accountant and such audit reveals an overstatement of Operating Expenses by Landlord of more than five percent (5%), then Landlord shall, within thirty (30) days after receipt of such audit, reimburse to Tenant any excess Operating Expenses previously paid to Landlord by Tenant and Landlord shall reimburse Tenant for the cost of such audit.

If Tenant is unable to conduct its ordinary business activities in the Premises because of any failure or interruption of any utility to the Premises for a period in excess of thirty (30) consecutive days (except if due to the negligence or willful misconduct of Tenant's Agents or if due to Tenant's failure to make repairs to the Premises as required hereunder), unless Landlord is exercising commercially reasonable efforts to restore the utility, Tenant shall have the right to terminate this Lease, without any liability to Landlord, upon five (5) days' prior written notice. Notwithstanding the foregoing, in the event such failure or interruption is caused by damage or destruction covered by Section 12 hereof, the provisions of Section 12 shall apply in lieu of the foregoing. Except as set forth in this section or in Section 12 hereof, failure by Landlord to furnish any service herein specified or any cessation thereof due to accident, making of repairs, alterations or improvements, weather, unusual difficulty or ability to obtain services or supplies from sources usually used for the Property, labor difficulties or other causes beyond Landlord's reasonable control shall not render Landlord liable in any respect for damages of any kind, nor be construed as an eviction of Tenant nor work an abatement of Rent. SECTION 12. DAMAGE OR DESTRUCTION 12.1 LOSS COVERED BY INSURANCE. If, at any time prior to the expiration or termination of this Lease, the Premises or the Building in which the Premises are located is wholly or partially damaged or destroyed by a casualty, which loss to Landlord is (except for any applicable deductible) fully covered by insurance maintained by Landlord or for Landlord's benefit (or required to be maintained by Landlord pursuant to Section 13), which casualty renders the Premises totally or partially inaccessible or unusable by Tenant in the ordinary conduct of Tenant's business, then: (a) REPAIRS WHICH CAN BE COMPLETED WITHIN NINE MONTHS. Within twenty (20) days of notice to Landlord of such damage or destruction, Landlord shall provide Tenant with notice of its determination of whether the damage or destruction can be repaired within nine (9) months of such damage or destruction without the payment of overtime or other premiums. If all repairs to such Premises or Building can, in Landlord's reasonable judgment, be completed within nine (9) months following the date of such damage or destruction without the payment of overtime or other premiums, Landlord, upon receipt of the insurance proceeds with respect thereto, shall at Landlord's expense promptly commence and diligently proceed to repair the same and this Lease shall remain in full force and effect and a proportionate reduction of the Rent shall be allowed 14 Tenant for such portion of the Premises as shall be rendered inaccessible or unusable to Tenant, and which is not used by Tenant, during the period of time that such portion is unusable or inaccessible and not used by Tenant. (b) REPAIRS WHICH CANNOT BE COMPLETED WITHIN NINE MONTHS. If all such repairs to the Building and Premises cannot, in Landlord's reasonable judgment, be completed within nine (9) months following the date of notice to Landlord of such damage or destruction without the payment of overtime or other premiums, Landlord shall notify Tenant of such determination and either Landlord or Tenant may, at its option, upon written notice to the other party given within thirty (30) days after the occurrence of such damage or destruction, elect to terminate this Lease as of the date of the occurrence of such damage or destruction. Notwithstanding the foregoing, if the damage does not affect the Premises, Landlord cannot terminate the Lease unless Landlord concurrently terminates all other leases in the Building. In the event that neither Landlord nor Tenant elects to terminate this Lease in accordance with the foregoing provisions, then Landlord, upon receipt of the insurance proceeds with respect thereto, shall at Landlord's expense promptly commence and diligently proceed to repair such damage or destruction, and in such event, this Lease shall continue in full force and effect but the Rent shall be proportionately reduced as hereinabove provided in Section 12.1(a); provided, however, that if any such repair is not commenced by Landlord within sixty (60) days after Landlord's receipt of the insurance proceeds to which it is entitled on account of such damage or destruction or is not substantially completed by Landlord within ten (10) months after the occurrence of such damage or destruction, then in either such event Tenant may, at its option, upon prompt written notice to Landlord, elect to terminate this Lease. 12.2 LOSS NOT COVERED BY INSURANCE. If, at any time prior to the expiration or termination of this Lease, the Premises or the Building in which the Premises are located is totally or partially damaged or destroyed from a casualty, which loss to Landlord is not fully covered (except for any deductible) by insurance maintained by Landlord or for Landlord's benefit (or required to be maintained by Landlord pursuant to Section 13), Landlord may, at its option, upon written notice to Tenant within thirty (30) days after notice to Landlord of the occurrence of such damage or destruction, elect to restore or repair such damage or destruction, or Landlord may elect to terminate this Lease so long as Landlord terminates every other lease in the Building which was affected by, the casualty. Notwithstanding the foregoing, Landlord may not elect to terminate this Lease if (i) the uninsured portion of the damage is less than ten percent (10%) of the replacement cost of the Building and/or (ii) Landlord does not elect to terminate the leases of all other tenants in the Building who are similarly affected by such damage and/or destruction. If Landlord elects to repair or restore such damage or destruction, Landlord shall promptly commence and diligently proceed to repair such damage and this Lease shall continue in full force and effect but the Rent shall be proportionately reduced as provided in Section 12.1(a). If Landlord does not elect by notice to Tenant to repair such damage the Lease shall terminate as of the date of the casualty. Notwithstanding the foregoing, if all repairs to the Premises or the Building required under this Section 12.2 cannot, in Landlord's reasonable 15 judgment, be completed within four (4) months following the date of such damage or destruction without the payment of overtime or other expenses, then either Landlord or Tenant may at its option, upon written notice to the other party given within thirty (30) days after the occurrence of such damage or destruction, elect to terminate this Lease as of the date of the occurrence of such damage or destruction. 12.3 DESTRUCTION DURING FINAL YEAR. Notwithstanding anything to the contrary contained in Sections 12.1 and 12.2 hereof, if the Premises or the Building in which the Premises are located is wholly or partially damaged or destroyed within the final twelve (12) months of the Term of this Lease, so that Tenant shall be prevented from using the Premises for forty five (45) consecutive days due to such damage or destruction, then either Landlord or Tenant may, at its option, by notice to the other party within thirty (30) days after the occurrence of such damage or destruction, elect to terminate this Lease effective as of the date of casualty. 12.4 DESTRUCTION OF TENANT'S PERSONAL PROPERTY, TENANT IMPROVEMENTS OR PROPERTY OF TENANT'S EMPLOYEES. In the event of any damage to or destruction of the Premises or the Building, under no circumstances shall Landlord be required to repair any injury, or damage to, or make any repairs to or replacements of Tenant's Improvements but Landlord shall be obligated to repair or replace the Initial TI's. Landlord shall have no responsibility for any contents placed or kept in or on the Premises or the Building by Tenant or Tenant's agents or employees. SECTION 13. INSURANCE AND INDEMNITY 13.1 INSURANCE ON TENANT'S PROPERTY. Tenant shall during the Term provide insurance coverage against loss or damage by fire and such other risks as are from time to time included in a standard or special extended coverage endorsement insuring Tenant's merchandise, trade fixtures, furnishings, equipment and all other items of personal property of Tenant. 13.2 TENANT'S LIABILITY INSURANCE. Tenant shall procure at its sole cost and expense and keep in effect from the date of this Lease and at all times during the Term either comprehensive general liability insurance or commercial general liability insurance applying to the use or occupancy of the Premises, and contractual liability insurance applying to Tenant's indemnity obligations under this Lease with respect to bodily injury, property damage, or other loss covered by Tenant's liability insurance. Such coverage shall be written by insurance companies reasonably acceptable to Landlord and its Lender and shall have a minimum combined single limit of liability of at least three million dollars ($3,000,000.00). All such policies shall be written to apply to all bodily injury, property damage or other covered loss occurring during the policy term, shall be endorsed to add Landlord as an additional named insured, to provide that such coverage shall be primary and that any insurance maintained by Landlord shall be excess insurance only. All such insurance shall provide for severability of interests; shall provide that an act or omission of one of the named insureds shall not reduce or 16 avoid coverage to the other named insureds; and shall afford coverage for all claims based on acts, omissions, injury and damage, which claims occurred or arose (or the onset of which occurred or arose) in whole or in part during the policy period. 13.3 FIRE AND EXTENDED COVERAGE INSURANCE. Landlord shall maintain insurance on the Building and the Premises against damage by fire and those perils now specified in the most current standard extended coverage endorsement in an amount equal to the full insurable cost of the Building and the Premises, excluding any of Tenant's Improvements and Alterations, as reasonably determined by Landlord, exclusive of excavations and foundations and subject to such "deductibles" as Landlord may reasonably determine. In addition, Landlord shall maintain loss of rent insurance and a policy of commercial general liability and property damage insurance. All insurance proceeds payable under Landlord's insurance carried hereunder shall by payable solely to Landlord. 13.4 WAIVER OF SUBROGATION. To the extent permitted by law and without affecting the coverage provided by insurance required to be maintained hereunder, Landlord and Tenant each waive any right to recover against the other on account of any and all claims Landlord or Tenant may have against the other with respect to any risk insured against by insurance actually carried, or required to be carried hereunder. Each casualty insurance policy carried by Landlord or Tenant hereunder, or which either may obtain with respect to the Premises or the Property independent of obligations hereunder, shall provide that the insurer waives all rights of recovery by way of subrogation against Landlord or Tenant in connection with all matters included within the scope of the waiver of recovery contained in this Section 13.4. 13.5 TENANT'S INDEMNITY. To the fullest extent permitted by law, Tenant shall indemnify Landlord, and its officers, directors, partners, employees, servants, and agents, and all mortgagees or beneficiaries of Landlord's interest in all or any portion of the Property, (collectively, "RELATED ENTITIES") against and save Landlord and its Related Entities harmless from and defend Landlord and Related Entities through attorneys reasonably satisfactory to Landlord from and against any and all claims, loss, cost, liability, damage and expense including, without limitation, penalties, fines and reasonable attorneys' fees (collectively, "CLAIMS"), incurred in connection with or arising in whole or in part from the activities of Tenant or Tenant's Related Entities, or any negligence or willful misconduct by Tenant or Tenant's Related Entities, excluding any Claims to the extent arising out of: (i) the negligence or willful misconduct of Landlord or Landlord's Related Entities, or (ii) Landlord's breach of this Lease. 13.6 LANDLORD'S INDEMNITY. To the fullest extent permitted by law, Landlord shall indemnify Tenant and its officers, directors, shareholders, partners, employees, servants and agents (collectively "RELATED ENTITIES") against and save Tenant and its Related Entities harmless from and defend Tenant and its Related Entities through attorneys reasonably satisfactory to Tenant from and against any and all Claims incurred in connection with or arising in whole or in part from the activities of Landlord or Landlord's Related Entities or any 17 negligence or willful misconduct of Landlord or Landlord's Related Entities, excluding any Claims to the extent arising out of: (i) the negligence or willful misconduct of Tenant or Tenant's Related Entities, or (ii) Tenant's breach of this Lease. SECTION 14. EMINENT DOMAIN 14.1 EFFECT OF TAKING. If all of the Premises is condemned or taken in any manner before or during the Term for public or quasi-public use, or any transfer of the Premises is made in avoidance of an exercise of the power of eminent domain (each of which acts shall be referred to as a "TAKING"), this Lease shall automatically terminate as of the date of the vesting of title as a result of such taking. If a part of the Premises is so taken, this Lease shall automatically terminate as to the portion of the Premises so taken as of the date of the vesting of title as a result of such taking. If such portion of the Property is taken as to render the Property incapable of economically feasible operation or to require a substantial alteration or reconstruction of the remaining portions thereof, this Lease may be terminated by Landlord, as of the date of the vesting of title as a result of such taking, by written notice to Tenant within sixty (60) days following notice to Landlord of the date of which said vesting will occur. If such portion of the Premises is taken as, in the reasonable opinion of Tenant, to materially impair the ability of Tenant to use and conduct its business from the Premises, this Lease may be terminated by Tenant as of the date of the vesting of title as a result of such taking, by written notice to Landlord within sixty (60) days following notice to Tenant of the date of which said vesting will occur. 14.2 AWARD. Landlord shall be entitled to the entire award for any taking; provided, however, that Landlord shall have no interest in any award made to Tenant for its leasehold interest, relocation expenses, the taking of personal property and fixtures belonging to Tenant or the interruption of or damage to Tenant's business, or attributable to improvements of the Premises actually paid by Tenant. 14.3 ABATEMENT OF RENT. In the event of a partial or temporary taking that does not result in a termination of this Lease as to the entire Premises, the Rent shall abate in proportion to the portion of the Premises taken or rendered untenable by such taking. Tenant hereby waives and releases its rights under Section 1265.130 of the California Code of Civil Procedure or any similar statute now or hereafter in effect. SECTION 15. SUBLEASE AND ASSIGNMENT 15.1 CONSENT REQUIRED. Subject to Section 15.5 hereof, Tenant shall not sell, assign, encumber, pledge or otherwise transfer or hypothecate all or any part of the Premises or Tenant's leasehold estate hereunder (each such act is referred to herein as an "ASSIGNMENT"), or sublet the Premises or any portion thereof or permit the Premises to be occupied by anyone other than Tenant (each such act is referred to herein as a "SUBLEASE") without Landlord's prior written 18 consent in each instance, which consent shall not be unreasonably withheld and shall be given or withheld within ten (10) business days after Tenant's delivery of request therefor, together with all information required to be provided to Landlord under Section 15.2. 15.2 NOTICE. Tenant shall have no right to enter into an Assignment or a Sublease unless Tenant shall have first requested in writing Landlord's consent to such Assignment or Sublease. Any request by Tenant for Landlord's consent to a specific Assignment or Sublease shall include (a) the name of the proposed assignee, subtenant or occupant, (b) the nature of the proposed assignee's, subtenant's or occupant's business to be carried on in the Premises, (c) a copy of the proposed Assignment or Sublease, and (d) such financial information as Landlord may reasonably request concerning the proposed assignee, subtenant or occupant or its business. 15.3 CONDITIONS OF APPROVAL. Without limiting the circumstances under which it may be reasonable for Landlord to withhold its consent to an Assignment or Sublease, it is expressly agreed that it shall be reasonable for Landlord to withhold its consent if Landlord reasonably determines that (i) the character or value of the Building are likely to be adversely affected during the Term as a result of such Assignment or Sublease, or (ii) the financial condition of the proposed new tenant or subtenant at the time of the proposed Assignment or Sublease is, in the reasonable opinion of Landlord, insufficient to meet the obligations of Tenant being assigned to such new tenant or subtenant. 15.4 COST OF PROCESSING REQUEST. Tenant shall reimburse Landlord for Landlord's reasonable attorneys' fees for the review and documentation of any proposed Assignment or Sublease within thirty (30) days after Landlord gives notice to Tenant of the amount thereof, together with reasonable documentation supporting such fees. 15.5 SCOPE OF ASSIGNMENT. Any sale or other transfer of a majority of (i) the partnership interests in Tenant or any beneficial interest therein, if Tenant is a partnership, or (ii) the capital stock in Tenant, or any beneficial interest therein, if Tenant is a corporation, shall be an Assignment for purposes of this Lease. The sale or other transfer of more than fifty percent (50%), by value, of the assets of Tenant used in conducting its business in the Premises shall also constitute an Assignment for purposes of this Lease. Notwithstanding anything to the contrary contained in this Section 15, Tenant may assign or sublet the Premises, or any portion thereof, without Landlord's consent, to any entity which controls, is controlled by or is under common control with Tenant, or to any entity resulting from the merger or consolidation with Tenant, or to any entity which acquires all or substantially all the assets of Tenant as a going concern of the business that is being conducted on the Premises, and any such Assignment shall not be subject to the provisions of Section 15.7 below. 15.6 ASSUMPTION OF OBLIGATIONS. Each assignee subtenant or other transferee of all or a portion of Tenant's interest hereunder, other than Landlord, shall assume, as provided in this Section 15.6, all obligations of Tenant under this Lease and shall be and remain liable jointly, and 19 severally with Tenant for the payment of Rent, and for the performance of all the terms, covenants, conditions and agreements herein contained on Tenant's part to be performed during the Term; provided, however, that a sublessee shall be liable to Landlord for Rent only in the amount set forth in the Sublease. 15.7 EXCESS RENT; RECAPTURE RIGHTS. Landlord's right to the portion of excess rent specified in this Section 15.7 is expressly reserved from the grant of Tenant's leasehold estate. Landlord shall have such right to such portion of the excess rent in the event of any Assignment or Sublease by any succeeding subtenant or assignee, regardless of whether (i) the instrument effecting any such Assignment or Sublease provides such right to Landlord, or (ii) Landlord has approved such an instrument which fails to provide such right to Landlord. If Landlord consents to any Assignment or Sublease, then Tenant shall pay to Landlord within five (5) business days after Tenant's receipt thereof, 50% of any and all consideration, as calculated pursuant to the following sentence, received by Tenant on account of such transaction, howsoever the same may be denominated, and in the case of Subleases, to the extent that such consideration exceeds the pro rata portion of the Fixed Rent and other charges payable by Tenant hereunder attributable to the sublet portion of the Premises, based on the net Rentable Area of the Promises and the net Rentable Area of the Premises sublet. In calculating the consideration subject to the preceding sentence, the following items shall be deducted therefrom: (a) the reasonable costs paid by Tenant for additional improvements installed in the portion of the Premises subject to such assignment or sublease by Tenant for the specific subtenant or assignee in question, amortized over the term of such assignment or sublease with interest thereon at the rate paid by Tenant on funds borrowed for the purpose of making such improvements or at the Interest Rate if Tenant does not borrow funds for such purpose and (b) reasonable leasing commissions paid by Tenant in connection with such assignment or subletting. Section 16. DEFAULT: REMEDIES 16.1 EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an "EVENT OF DEFAULT" by Tenant: (a) ABANDONMENT. Abandonment of the Premises without payment of Rent. Tenant's vacation of the Premises and concurrent efforts to sublet the Premises or assign the Lease is not an abandonment of the Premises, provided that Tenant is timely paying Rent. (b) NONPAYMENT OF MONEY. Failure to pay Rent or any other sum due and payable by Tenant under this Lease. (c) OTHER OBLIGATIONS. Failure to perform any term, obligation, condition, agreement or covenant under this Lease, other than nonpayment of money. (d) INSOLVENCY. The admission by Tenant in writing of its inability to pay its debts as they become due; the filing by Tenant of a petition seeking any reorganization, arrangement, 20 composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation, the filing by Tenant of an answer admitting or failing timely to contest a material allegation of a petition filed against Tenant in any such proceedings or, if within thirty (30) days after the commencement of any proceeding against Tenant seeking any such relief, such proceeding shall not have been dismissed; the appointment of a receiver or trustee to take possession of all or substantially all of the assets of Tenant unless such appointment is vacated or annulled within sixty (60) days; a general assignment by Tenant for the benefit of creditors; any action or proceeding commenced by Tenant under any insolvency or bankruptcy act, or under any other statute or regulation having as its purpose the protection of creditors, or any such action commenced against Tenant and not discharged within thirty (30) days after the date of commencement, or the attachment, execution or other judicial seizure of all or substantially all of Tenant's assets or the Premises, if such attachment or other seizure remains undismissed or undischarged for a period of ten (10) days after the levy thereof. 16.2 NOTICE TO TENANT. Upon the occurrence of any Event of Default, Landlord shall give Tenant written notice thereof, specifying the Event of Default and the provisions of this Lease breached by Tenant and Tenant shall have the right to cure such Event of Default within the time periods, if any, hereinafter specified. (a) NONPAYMENT OF MONEY. For failure to pay Rent or any other sum, within ten (10) days after Landlord's notice. (b) OTHER OBLIGATIONS. For failure to perform any term, obligation, condition, agreement or covenant under this Lease, other than nonpayment of monies, thirty (30) days after Landlord's notice. Notwithstanding the foregoing, if such failure cannot reasonably be cured within such 30-day period, Tenant shall continue to have the right to cure and shall not be in default under this Lease if Tenant commences within such 30-day period such cure and thereafter diligently prosecutes the same to completion. No notice or cure period shall be required or applicable hereunder for any Event of Default specified in Section 16.1(d) except as expressly set forth in Section 16.1(d) of this Lease. 16.3 REMEDY UPON OCCURRENCE OF UNCURED EVENT OF DEFAULT. On the occurrence of an uncured Event of Default, Landlord shall have the right either (i) to terminate this Lease, and at any time thereafter recover possession of the Premises, or any part thereof, and expel and remove therefrom Tenant and any other person occupying the same, by any lawful means, and again repossess and enjoy the Premises without prejudice to any of the remedies that Landlord may have under this Lease, or at law or equity by reason of the Event of Default or of such termination, or (ii) to continue this Lease in effect for so long as Landlord does not so terminate Tenant's right to possession, and enforce all Landlord's rights and remedies under this Lease, including the right to (A) recover Fixed Rent and Additional Charges as they become due, or(B) relet the Premises at such rental and upon such terms and conditions as Landlord, in its reasonable discretion, may deem advisable. Acts of maintenance, preservation or efforts to lease 21 the Premises, the appointment of a receiver upon application of Landlord to protect Landlord's interest under this Lease, or re-entry or taking of possession of the Premises by Landlord hereunder, shall not constitute an election to terminate Tenant's right to possession unless specific written notice of such termination is given to Tenant hereunder. Notwithstanding any relating without termination, Landlord may at any time thereafter elect to terminate this Lease pursuant to this Section 16.3. Provided Tenant cooperates with Landlord, Landlord agrees to make reasonable efforts to mitigate its damages arising from an uncured Event of Default by Tenant. 16.4 DAMAGES UPON TERMINATION. If Landlord terminates this Lease pursuant to Section 16.3, Landlord may exercise all rights and remedies available to a landlord at law or in equity, including, without limitation, the right to recover from Tenant: (i) the worth at the time of award of the unpaid Rent and other amounts payable by Tenant hereunder which had been earned at the time of termination; (ii) the worth at the time of award of the amount by which the unpaid Rent and such other amounts which would have been earned after termination until the time of the award exceeds the amount of loss of Rent and such other amounts that the Tenant proves could have been reasonably avoided; (iii) the worth at the time of award of the amount by which the unpaid Rent and such other amounts for the balance of the term after the time of the award exceeds the amount of loss of Rent and such other amounts that the Tenant proves could be reasonably avoided; and (iv) any other amount necessary to compensate Landlord for all the direct costs proximately caused by Tenant's failure to perform its obligations under this Lease or which, in the ordinary course of things, would be likely to result therefrom. The "worth at the time of award" of the amounts referred to in clauses (i) and (ii) shall be computed with Interest. The "worth at the time of award" of the amounts referred to in clause (iii) shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco, California, plus one percent (1%). As used herein, "time of award" shall mean either the date upon which Tenant pays to Landlord the amount recoverable by Landlord as hereinabove set forth, or the date of entry of any determination, order or judgment, of any court or other legally constituted body determining the amount recoverable, whichever first occurs. 16.5 COMPUTATION OF RENT AND OTHER AMOUNTS FOR PURPOSES OF DEFAULT. For purposes of Section 16.4, unpaid Rent and other amounts which would have accrued and become payable under this Lease shall consist of the sum of: (i) the total Fixed Rent for the balance of the Term, plus (ii) a computation of Tenant's Share of the Operating Expenses for the balance of the Term. 16.6 LANDLORD'S RIGHT TO PERFORM ON TENANT'S BREACH. In addition to any other right or remedy of Landlord hereunder, upon the occurrence of an uncured Event of Default and without waiving or releasing Tenant from any obligation of Tenant hereunder, Landlord may (but shall not be required) to cure such uncured Event of Default for the account of Tenant. Landlord shall not be responsible or liable to Tenant for any loss or damage that may be caused to Tenant's stock or business by reason of effecting cure hereunder, unless caused by the gross 22 negligence or willful misconduct of Landlord or Landlord's Agents. All sums paid by Landlord and all costs and expenses incurred by Landlord in connection with such cure (including attorneys' fees), together with interest thereon at the Interest Rate from the respective dates of Landlord's payment of each item of cost or expense, shall be payable by Tenant on demand. 16.7 LANDLORD'S DEFAULTS. (a) NOTICE AND CURES: LANDLORD'S LIABILITY. If Landlord fails to perform any of its obligations under this Lease, then Tenant shall give Landlord written notice thereof, specifying with particularity the breach claimed by Tenant. Except for Landlord's failure to make repairs required under Section 10.1, Landlord shall have the right to cure such breach during the 30-day period following receipt of Tenant's notice hereunder, unless such breach cannot reasonably be cured within such 30-day period, in which event Landlord shall not be in default under this Lease if Landlord commences within such 30-day period such cure and thereafter diligently prosecutes the same to completion. Notwithstanding the foregoing, if such breach causes immediate damage to Tenant's personal property or the ordinary conduct of Tenant's business, such as roof leaks, Landlord shall use commercially reasonable efforts to cure such breach as soon as possible. In addition, in the event Landlord fails to cure such breach within the time period set forth herein, Tenant shall have the right, but not the obligation, to cure such breach and the reasonable costs and expenses incurred by Tenant in connection with such cure, together with interest thereon at the Interest Rate from the respective date(s) of Tenant's payment of each item of cost or expense, shall be payable by Landlord upon demand. If the Premises, or any portion thereof, are at any time subject to any mortgage or a deed of trust, and either Landlord or the mortgagee or beneficiary has notified Tenant of the existence of such mortgage or deed of trust, Tenant shall serve on the mortgagee or beneficiary thereunder concurrent copies of any notice of default served on Landlord hereunder at the last address for such mortgagee or beneficiary of which Tenant has received notice from Landlord, and such mortgagee or beneficiary shall have an additional period of 30 days after expiration of Landlord's cure period to accomplish the cure of Landlord's default. (b) RECOVERY AGAINST LANDLORD. Tenant shall look solely to Landlord's interest in the Property for the recovery of any judgment against Landlord. Landlord, or if Landlord is a partnership, its partners whether general or limited, or if Landlord is a corporation, its directors, officers and shareholders, shall not be personally liable for any such judgment. 16.8 WAIVER; REMEDIES CUMULATIVE. Failure of Landlord or Tenant to declare an Event of Default immediately upon the occurrence thereof, or delay in taking any action in connection therewith, shall not waive such Event of Default, but Landlord or Tenant shall have the right to declare any such Event of Default at any time thereafter. No waiver by Landlord or Tenant of an Event of Default, or any agreement, term, covenant or condition contained in this Lease, shall be effective or binding on the other party unless made in writing and no such waiver shall be 23 implied from any omission by Landlord or Tenant to take action with respect to such Event of Default or other such matter. SECTION 17. SUBORDINATION, ATTORNMENT AND ESTOPPEL 17.1 SUBORDINATION. Without the necessity of any additional document being executed by Tenant for the purpose of effecting a subordination, this Lease, and all of Tenant's rights under this Lease, shall be subject and subordinate at all times to the lien of any mortgage or deed of trust or other security instrument (and any advances or interest thereunder) that may now exist or hereafter be executed in any amount for which the Property or any portion thereof, is specified as security, and all modifications, renewals, supplements, consolidations and replacements thereof, provided that the rights of Tenant herein are not disturbed so long as no Event of Default by Tenant shall have occurred and be continuing. If any such mortgagee or beneficiary so elects in writing, then this Lease shall be superior to the lien of the mortgage or deed of trust held by such mortgagee or beneficiary, whether this Lease is dated or recorded before or after such mortgage or trust deed. Tenant shall promptly execute and deliver, upon demand by Landlord and in substantially the form reasonably requested by Landlord, any additional documents evidencing the priority or subordination of this Lease, provided such documents contain the nondisturbance agreement described in Section 17.2 hereof. 17.2 ATTORNMENT BY TENANT: NON DISTURBANCE. Upon enforcement of any rights or remedies under any mortgage or deed of trust to which this Lease is subordinated (including, without limitation, proceedings for judicial or power of sale foreclosure, or deed in lieu of foreclosure delivered by Landlord to the mortgagee or beneficiary thereunder), Tenant shall attorn to the purchaser or transferee under such right or remedy and recognize such purchaser or transferee as Landlord under this Lease. If Tenant attorns hereunder, then, so long as there is no uncured Event of Default, Tenant shall not be disturbed in its possession of the Premises. Tenant shall execute and deliver any reasonable document or instrument required by such purchaser or transferee confirming the attornment hereunder. 17.3 CERTIFICATES. Each of Tenant and Landlord, at any time during the Term and from time to time, shall execute, acknowledge and deliver to the requesting party, addressed to such party or any prospective purchaser or mortgagee of any part of the Property a certificate stating: (a) that Tenant has accepted the Premises (or, if Tenant has not done so, that Tenant has not accepted the Premises and specifying the reasons therefor), (b) the Commencement Date and Expiration Date of this Lease, (c) that this Lease is unmodified and in full force and effect (or, if there have been modifications, that this Lease is in full force and effect as modified and stating the modifications), (d) whether or not the requested party is aware of any then existing defenses against the enforcement of any of the obligations of the requested party under this Lease (and, if so, specifying same), (e) whether or not the requested party is aware of any then existing defaults by the requesting party in the performance of its obligations under this Lease (or acts or omissions which would constitute defaults if uncured after notice), and, if so, specifying same, 24 (f) the dates, if any, to which the Rent and Additional Charges and other amounts under this Lease have been paid, (g) use of and knowledge with respect to Hazardous Materials by Tenant or Landlord under, over and upon the Premises, and (h) any other information and statements that may reasonably be required by the requesting party. SECTION 18. FEES AND EXPENSES; PAYMENT 18.1 INTEREST ON PAST DUE OBLIGATIONS. Unless otherwise specifically provided herein, any amount due from Tenant to Landlord under this Lease (including, without limitation, any payment of Rent) which is not paid within ten (10) after written notice to Tenant (except no notice need be given for failure to make any payment of Fixed Rent) shall bear interest from the due date until paid at the Interest Rate. The payment of such interest shall not alone excuse or cure any default under this Lease. 18.2 LATE CHARGES. Tenant acknowledges that late payment by Tenant to Landlord of Rent will cause Landlord to incur costs not contemplated by this Lease, the exact amount of such costs being extremely difficult and impracticable to fix. Such costs include, without limitation, processing and accounting charges, and late charges that may be imposed on Landlord by the terms of any encumbrance and note secured by any encumbrance covering the Premises. Therefore, in addition to the provisions of Section 18.1, if any installment of Rent due from Tenant is not received within ten (10) days after written notice to Tenant (except no notice need be given for failure to make any payment of Fixed Rent) by Landlord, Tenant shall pay to Landlord an additional sum of five percent (5%) of the overdue Rent as a late charge. The parties agree that this late charge represents a fair and reasonable estimate of the costs that Landlord will incur by reason of late payment by Tenant. Section 19. ACCESS TO PREMISES 19.1 LANDLORD ACCESS. Landlord reserves for itself and its agents, employees and independent contractors the right to enter the Premises at all reasonable times and upon reasonable notice (i) to inspect the Premises. (ii) to supply any service to be provided by Landlord to Tenant hereunder, (iii) to show the Premises to prospective purchasers, mortgagees or tenants, (iv) to post notices of non-responsibility, (v) to determine whether Tenant is complying with its obligations under this Lease. (vi) to alter, improve or repair the Premises or any other portion of the Building and (vii) for any other lawful purpose not inconsistent with Tenant's rights hereunder. Any entry by, Landlord or Landlord's Agents pursuant to this section shall, except in the case of any emergency, be upon forty eight (48) hours' advance written or oral notice to Tenant. Landlord shall comply with Tenant's security, safety and other procedures applicable to the Premises and shall not unreasonably interfere with Tenant's use of the Premises or the conduct of Tenant's business therein while in the Premises. Provided Landlord complies with the requirements of this section. Tenant hereby waives any claim for damages for any injury or inconvenience to or interference with Tenant's business, any loss of occupancy, or quiet 25 enjoyment of the Premises, any right to abatement of Rent, or any other loss occasioned by Landlord's exercise of any of its rights under this Section 19, unless caused by the negligence or willful misconduct of Landlord or its agents, employees or contractors. Landlord shall have the right to use any and all means that Landlord may reasonably deem necessary or proper in order to obtain entry to any portion of the Premises in an emergency. Section 20. NOTICES Except as otherwise expressly provided in this Lease, any bills, statements, notices, demands, requests or other communications given or required to be given under this Lease shall be effective only if rendered or given in writing, and either sent by overnight delivery service or registered or certified mail, return receipt requested, addressed (a) to Tenant (i) at the Premises, or (ii) at Tenant's last known address or at any place where Landlord believes that Tenant or any agent or employee of Tenant may be found, if sent subsequent to Tenant's vacating, deserting, abandoning or surrendering the Premises, (b) to Landlord at Landlord's Address, or (c) to either Landlord or Tenant at such other address as either Landlord or Tenant may designate as its new address for such purpose by notice given to the other in accordance with the provisions of this Section 20. Any such bill, statement, notice, demand, request or other communication shall be deemed to have been rendered or given (i) on the date it is officially recorded as delivered to the intended recipient by return receipt or equivalent, and, in the absence of such record of delivery, the effective date shall be presumed to have been the third (3rd) business day after the date when it shall have been deposited in the mail as provided in this Section 20 if sent by registered or certified mail. If Tenant is notified of the identity and address of any mortgagee of Landlord, Tenant shall give to such mortgagee by registered or certified mail written notice of any default by Landlord or failure by Landlord to perform any of its obligations hereunder. Section 21. RULES AND REGULATIONS Tenant shall faithfully observe and comply with the rules and regulations for the Building, a copy of which has been provided to Tenant, and all reasonable modifications thereof and additions thereto which are applicable to multiple tenants and which do not adversely affect Tenant in a material way from time to time put into effect by Landlord. Landlord shall have the right to promulgate different rules and regulations applicable to different portions of the Building, but Landlord shall not have the right to promulgate rules and regulations applicable only to Tenant. If there is any conflict between the terms of the rules and regulations and any provision of this Lease, the terms of this Lease shall govern. Landlord shall not be responsible for the nonperformance by any other tenant or occupant of the Building of any of such rules and regulations. Landlord's consent where required under the rules and regulations shall not be unreasonably, withheld, conditioned or delayed. 26 Section 22. SECURITY DEPOSIT Tenant agrees to deposit with Landlord the Security Deposit, if any, set forth in the Basic Lease Information within five (5) days after mutual execution of this Lease, as security for Tenant's faithful performance of its obligations under this Lease. Landlord and Tenant agree that the Security Deposit may be commingled with other funds of Landlord. If Tenant fails to pay any Rent or other amount when due and payable under this Lease, or fails to perform any of the terms hereof, Landlord may appropriate and apply or use all or any portion of the Security Deposit for Rent payments or any other amount then due and unpaid, for payment of any amount for which Landlord has become obligated as a result of Tenant's default or breach, and for any loss or damage sustained by Landlord as a result of Tenant's default or breach, and Landlord may so apply or use this deposit without prejudice to any other remedy Landlord may have by reason of Tenant's default or breach. If Landlord so uses any of the Security Deposit, Tenant shall, within ten (10) days after written demand therefor, restore the Security Deposit to the full amount originally deposited; Tenant' failure to do so shall constitute an act of default hereunder. If Tenant performs all of Tenant's obligations hereunder, the Security Deposit, or so much thereof as has not theretofore been applied by Landlord, shall be returned to Tenant (or to the last permitted assignee, if any, of Tenant's interest hereunder) within fifteen (15) days after the end of the Lease. If Landlord sells its interest in the Premises, Landlord shall deliver this deposit to the purchaser of Landlord's interest and thereupon be relieved of any further liability or obligation with respect to the Security Deposit. Section 23. SURRENDER OF PREMISES ON TERMINATION On the Expiration Date or earlier termination of the Term, Tenant shall quit and surrender the Premises to Landlord, broom clean, in good order, condition and repair as required by Section 10.1, ordinary wear and tear, fire and other casualties, acts of God or other causes beyond the control of Tenant excepted, and Tenant shall comply with the provisions of Section 9.2 of this Lease. Unless Landlord expressly agrees in writing to the contrary, Tenant shall remove all machinery, equipment, trade fixtures and materials that Tenant has placed on the Premises and Tenant shall repair any and all damage to the Premises caused by Tenant's removal of such equipment, machinery, trade fixtures and materials. Section 24. MISCELLANEOUS 24.1 SUCCESSORS AND ASSIGNS. Subject to the provisions of Section 15 regarding assignment and subleasing by Tenant, the terms, covenants and conditions contained in this Lease shall bind and inure to the benefit of Landlord and Tenant and, except as otherwise provided herein, their respective personal representatives and successors and assigns; provided, however, that upon the sale, assignment or transfer by Landlord (or by any subsequent landlord) of its interest in the Building or the Property as owner or lessee, including any transfer upon or in lieu of foreclosure or by operation of law, Landlord (or subsequent landlord) shall be relieved 27 from all subsequent obligations or liabilities under this Lease. Provided that Landlord delivers the Security Deposit, if any, to its successor, Landlord shall have no further liability to Tenant with respect thereto. 24.2 CONSTRUCTION. This Lease shall be governed by and construed in accordance with the laws of the State of California. Any actions or proceedings brought under this Lease, or with respect to any matter arising under or out of this Lease, shall be brought and tried only in courts located in the County of Contra Costa, California (excepting appellate courts). 24.3 INTEGRATION. The terms of this Lease are intended by the parties as a final expression of their agreement with respect to such terms as are included in this Lease, and may not be contradicted by evidence of any prior or contemporaneous agreement, arrangement, understanding or negotiation (whether oral or written). The parties further intend that this Lease constitute the complete and exclusive statement of its terms, and no extrinsic evidence whatsoever may be introduced in any judicial proceeding involving this Lease. The language in all parts of this Lease shall in all cases be construed as a whole and in accordance with its fair meaning and not restricted for or against any party. 24.4 LIGHT, AIR, VIEW, SIGNS, ETC. Tenant covenants and agrees that no diminution of light, air or view, or any impairment of the visibility of the Premises from inside or outside the Building, by any structure or other object that may hereafter be erected (whether or not by Landlord) shall entitle Tenant to any reduction of Rent under this Lease, constitute an actual or constructive eviction of Tenant, result in any liability of Landlord to Tenant, or in any other way affect this Lease or Tenant's obligations hereunder. Landlord shall have the exclusive right to use all exterior walls, roofs and other portions of the Building for signs, notices and other reasonable promotional purposes. Tenant shall not place or allow to be placed in, on or about the Building any sign or other notice indicating Tenant's desire to assign this Lease or sublet the Premises . 24.5 HOLDING OVER. If Tenant remains in possession of the Premises after the expiration of the Term with the express written consent of Landlord and without executing a new lease, then such holding over shall be deemed a tenancy from month-to-month, subject to all conditions, provisions and obligations of this Lease. No holding over by Tenant after the Term shall operate to extend the Term. In the event of any unauthorized holding over, Landlord and Tenant agree that Landlord's damages, including any claims for damages by any other tenant to whom Landlord may, have leased all or any part of the Premises, would be difficult to establish. Landlord and Tenant desire to liquidate the damages payable to Landlord in the event Tenant holds over after the term without Landlord's consent and therefore agree upon damages payable by Tenant to Landlord in a daily amount equal to 1/30th of the monthly Fixed Rent in effect immediately, prior to the holding over which daily amount shall increase by five percent (5%) per day but in no event more than 100%, such that for example, on the tenth day the increase for 28 such day would be 50%. Landlord and Tenant agree that the above described formula to establish damages is fair and reasonable. 24.6 COUNTERPARTS. This Lease may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 24.7 BROKER'S COMMISSIONS. Landlord shall pay all brokers commissions payable to the Brokers listed in the Basic Lease Information in connection with this transaction. Tenant represents and warrants that other than such Brokers, Tenant has not entered into any agreement or incurred or created any obligation which might require Landlord to pay any broker's commission, finder's fee or other commission or fee relating to the leasing of the Premises, unless disclosed to and accepted by Landlord in writing before the date hereof, and Tenant shall defend, indemnify and hold harmless Landlord from and against any claims for any such commissions or fees by anyone claiming by or through Tenant. 24.8 LANDLORD'S CONSENTS. Unless otherwise expressly provided in this Lease, all consents and approvals to be given by Landlord may be withheld for any reason or no reason, at Landlord's sole discretion, and any such action shall not be deemed inconsistent with any covenant of good faith and fair dealing otherwise implied by law to be a part of this Lease. Landlord's failure to respond to a request for consent or approval from Tenant with thirty (30) days (or such other period as may be provided in this Lease) shall be deemed to constitute the granting of such consent or approval. 24.9 AMENDMENTS. No amendments or modifications of this lease or any agreements in connection therewith shall be valid unless in writing duly executed by both Landlord and Tenant. 24.10 CONFIDENTIALITY. Landlord shall keep and maintain as confidential and shall not disclose to third parties all information, documents and other data supplied by Tenant to Landlord pursuant to or in connection with this Lease that Tenant identifies as confidential at the time Tenant provides such information to Landlord; provided, however, that Landlord may disclose such information, documents and other data to its counsel and consultants who agree to keep it confidential and to the extent required by applicable governmental laws, orders, rules, ordinances and regulations. 24.11 ATTORNEYS' FEES. If either party becomes a party to any litigation concerning this Lease, the Premises, or the Property by reason of any act or omission of the other party or its authorized representatives. and not by reason of any act or omission of the party that becomes a party to that litigation, or any act or omission of its authorized representative, the party that causes the other party, to become involved in the litigation shall be liable to the party, involved for reasonable attorneys' fees and court costs incurred by it in the litigation. If either party commences an action against the other party arising out of or in connection with this Lease, or 29 institutes any proceeding in a bankruptcy or similar court which has jurisdiction over the other party or any or all of its property or assets, the prevailing party shall be entitled to have and recover from the losing party reasonable attorneys' fees and court costs. "PREVAILING PARTY" within the meaning of this Section 24.11 shall include a party who dismisses an action for recovery hereunder in exchange for payment of the sums allegedly due, performance of covenants allegedly breached or consideration substantially equal to the relief sought in the action. 24.12 NO DISCRIMINATION. There shall be no discrimination against or segregation of any person or group of persons, on account of race, color, creed, religion, sex, marital status, national origin, or ancestry, in the leasing, subleasing, transferring, use, occupancy, tenure, or enjoyment of the Premises, nor shall Tenant or any person claiming under or through Tenant, establish or permit any such practice of discrimination or segregation with reference to the selection, location, number, use, or occupancy, of tenants, lessees, sublessees, subtenants, or vends in the Premises. Landlord shall deliver to Tenant a copy of (a) any Covenants, Conditions and Restrictions affecting the Premises; and (b) any rules and regulations governing Tenant's use of the Premises. Tenant hereby acknowledges receipt of the aforementioned documents. Section 25. PARKING AND SIGNAGE 25.1 PARKING. During the Term, Tenant shall have the non-exclusive right to three (3) parking spaces per 1,000 square feet of the Rentable Area in the Premises.

Tenant shall not affix, paint, erect or inscribe any sign, projection, awning, or advertisement of any kind to any part of the Premises, Building, or Property, including, without limitation, the inside or outside of windows or doors, without the written consent of Landlord which shall not be unreasonably withheld, conditioned or delayed so long as such signage is consistent with signage generally approved by Landlord for the Property. Landlord agrees that subject to Tenant obtaining permission from the City of Richmond to the extent required therefor, Tenant may place signage on the Premises and the Property substantially the same as Tenant's signage on Phase I of Marina Bay Business Park.

Provided this Lease is in full force and effect and no Event of Default has occurred and is continuing at the time of Tenant's delivery, of the Extension Notice, Tenant shall have the right to extend the Term of this Lease for two five (5) year terms (each an "Extended Term") upon prior written notice of extension to Landlord given not later than twelve (12) months prior to the expiration of the initial Term or the Extended Term, as the case 30 may be ("Extension Notice"). It is understood and agreed that Tenant's submittal of each Extension Notice shall bind Tenant to a five (5) year extension of this Lease. Each Extended Term shall be on the same terms and conditions as provided in this Lease, except that (i) Tenant shall occupy the Premises in its then "AS IS" condition, and (ii) the Fixed Monthly Rent for the Extended Term shall be the greater of (x) 95% of the Fixed Monthly Rent in effect immediately prior to the commencement date of the Extended Term, or (y) the fair market rent as of the date that is eleven (11) months prior to the commencement of the Extended Term, as determined below: 26.2 FAIR MARKET RENT DETERMINATION. The fair market rent of the Premises as of the commencement of each Extended Term shall be determined as follows. Within fifteen (15) days after Landlord's receipt of the Extension Notice, Landlord shall notify Tenant of Landlord's reasonable opinion of the fair market rental value of the Premises.

If the two appraisals differ and the higher of the two does not exceed the lower by ten percent (10%), the two appraisals shall be averaged to determine the fair market rental value of the Premises. If the two appraisals differ by more than ten percent (10%), the two appraisers shall select a third person similarly qualified to act as a third appraiser; provided however that if the two appraisers are unable to agree on a third person to act as an appraiser, the third appraiser shall be selected by lot from names submitted by the two other appraisers. The third appraisal shall be promptly completed and if two of the three appraisers agree, their determination shall be the fair market rental value; if no two agree, the parties shall determine the fair market rental value by averaging the appraisals; provided, however, that if the lowest appraisal is less than ninety percent (90%) of the middle appraisal, then such lowest appraisal shall be disregarded in determining the average and the highest appraisal shall be disregarded in determining the average if the highest appraisal is more than one hundred ten percent (110%) of the middle appraisal. Landlord and Tenant shall each pay the appraiser it selects and one-half (1/2) of the costs and expenses of the third appraiser, if a third appraiser is necessary. 26.4 DEFINITION OF FAIR MARKET RENTAL VALUE. "Fair Market Rental Value" shall mean the fair market annual rental amount per rentable square foot that Landlord has accepted in current, comparable, new transactions in Marina Bay Business Park for comparable space, for a comparable period of time, from non-expansion, non-renewal, and non-equity, tenants, or if there are not a sufficient number of current comparable transactions in Marina Bay Business Park, what a willing, comparable, new, non-expansion, non-renewal, non-equity, tenant would 31 pay, and a willing comparable landlord of a comparable building with comparable vacancy factors in the vicinity of the Building would accept, at arm's length for a comparable amount of space for a comparable period of time, in either case giving appropriate consideration to the annual rental rates per rentable square foot, the standard of measurement by which the rentable square footage is measured, the ratio of rentable square feet to usable square feet, the type of escalation clauses, the extent of liability under the escalation clauses, and abatement provisions reflecting free rent and/or no rent during the period of construction or any other period during the lease term, brokerage commissions, if any, which would be payable by Landlord in a comparable transaction, length of the lease term, size and location of premises being leased, a fair market tenant improvement allowances and other generally applicable conditions of tenancy for the number of rentable square feet in the Premises so that Tenant will obtain the same rent and other economic benefits.
