If any such repair is caused by any act, omission or negligence of Tenant or its employees, agents, invitees, licensees, subtenants, or contractors, Landlord shall have the right to make the repair at Tenant's sole cost and expense, provided that if the damage necessitating such repairs is covered by insurance carried by Landlord or Tenant, the proceeds of such insurance shall be made available by Landlord, or by Tenant, as the case may be, to cover the cost of such repairs and the rights of any party, and of its insurer, shall be subject to the provisions of Section 21D. If Tenant requires maintenance, servicing, repair or replacement of any special plumbing, ventilating, air conditioning, electric, fire protection or sprinkler system installed for the Tenant's benefit in the Leased Premises, such as any special air extractor equipment, whether or not such system is tied into the standard Building systems, such maintenance, servicing, repair or replacement shall be made by Landlord, its agents, or contractors, or, if Landlord shall so determine, by engineers or contractors engaged by Tenant and approved by Landlord, but, in either event, at the sole expense of Tenant, unless the need for such repairs is caused solely by the negligence or willful misconduct of Landlord or Administrator, their contractors, agents or employees. Any repairs by Landlord for Tenant's account shall be performed by Administrator, or under Administrator's supervision and the cost of such repairs shall be at rates competitive in the San Xxxx market for work of the same type.

B. All replacement of lighting tubes, lamps, bulbs and ballasts required in the Leased Premises will be done by Landlord at Tenant’s expense.

C. Tenant shall maintain the Leased Premises and the fixtures and appurtenances therein including, but not limited to, ceilings, partitions, doors, lighting fixtures, switches, floor coverings, alterations, additions and Improvements made by Tenant in good order and repair, in a neat and clean condition, at all times, except that as set forth in Section 9A hereof, Administrator shall provide basic cleaning and extermination services to the Leased Premises. Landlord shall provide regular maintenance to and service the ventilating and air conditioning equipment servicing the Leased Premises (for example, without limitation, regular filter changes and fan belt replacement).

Except with regard to repair or replacement following a casualty or an eminent domain taking, or due to the negligence or willful misconduct of the Administrator or the Landlord, or as specified in Sections 11A or 11B above, the Tenant shall be responsible for all maintenance, repair and replacement of any kind and nature of the Leased Premises, at Tenant's sole expense. Except as specified in Section 11A or 11B and subject to Section 21D, Tenant shall reimburse Landlord for all costs and expenses of repairing and replacing all damage or injury to the Leased Premises and Building and to fixtures and equipment caused by Tenant or its employees, agents, invitees, licensees, subtenants, or contractors, or as the result of all or any of them moving in or out of the Building or by installation or removal of furniture, fixtures or other property.

Any cost or expense incurred by Landlord in making such repairs and chargeable to Tenant as herein provided shall constitute Additional Rent and shall be paid concurrently with the next installment of Additional Rent following Tenant's receipt of Landlord's invoice for such expenses and to the extent that Landlord is reimbursed therefor under any policy of insurance, the amount payable by Tenant hereunder shall be reduced by the amount of such reimbursement.

Except as provided below, there shall be no abatement of rent because of such repairs, alterations, additions or Improvements or because of any delay by Landlord in making the same or any interruption in any service to be provided by Landlord connected therewith, provided, however, that (a) Landlord shall use its best efforts to complete such work as soon as reasonably possible.

19. Eminent Domain.

A. In the event of exercise of the power of eminent domain whereby (i) such portion of the Building is taken such that access to the Leased Premises is permanently impaired thereby and Landlord has not provided reasonable alternate access within a time period that is reasonable under the circumstances, (ii) all or substantially all of the Leased Premises or the Building is taken, (iii) less than substantially all of the Building is taken but the Administrator, acting in good faith, determines that it is economically unfeasible to continue to operate the uncondemned portion of the Building as a first-class office building, or (iv) less than substantially all of the Leased Premises is taken, but Tenant, acting in good faith, determines that because of such taking it is economically unfeasible to continue to conduct its business in the uncondemned portion of the Leased Premises, then in the case of (i) or (ii) either party, in the case of (iii) Landlord, and in the case of (iv), Tenant, shall have the right to terminate this Lease as of the date when possession of all or that part of the Building is taken by or is required to be delivered or surrendered to the condemning authority; and in such case all rent and other charges payable hereunder shall be adjusted to the date of such termination. A taking shall include the transfer of the title or of any interest in the Building by deed or other instrument in settlement of or in lieu of transfer by operation of law incident to condemnation proceedings.

B. Unless this Lease shall have been terminated under A above, in the event a portion of the Building shall be condemned for public use or voluntarily transferred to a public or quasi-public body in lieu of proceeding to a judgment of condemnation, and Tenant shall determine that it is able to carry on its normal business operations, Tenant shall pay rent for only such portion which Tenant in its determination may reasonably occupy after such partial condemnation or transfer. All repairs by Landlord necessary to restore the Leased Premises or Building as nearly as possible to its original condition shall be:

(i) commenced within forty-five (45) days after the taking or transfer;

(ii) performed in a diligent and workmanlike manner with a material of at least the same quality utilized originally in the construction of the Building.

(iii) completed by Landlord at Landlord's sole expense with a minimum of interference with Tenant's normal business operations.

If in Tenant's determination landlord shall not have performed any of the above obligations in strict compliance therewith, then Tenant may, but shall not be required to, undertake such obligations, and all costs and expenses incurred by Tenant as a result thereof may be deducted from any rent or other payment due or to become due hereunder.

C. Tenant shall have no right to participate or share in any condemnation claim, damage award or settlement in lieu thereof with respect to any taking of any nature; provided, however, that Tenant shall not be precluded from claiming or receiving compensation for relocation and moving expenses, as permitted under applicable law.

20. Casualty Damage.

A. In the event that there has been damage to or destruction caused by fire or other casualty to (i) the Leased Premises, (ii) the entrances and other common facilities of the Building that provide normal access to the Leased Premises or other portions of the Building, or (iii) any equipment or portions thereof that are necessary for Administrator to provide services to the Leased Premises in accordance herewith:

(i) Upon the Landlord’s receipt of the insurance proceeds, if any, or upon Landlord’s determination that there has been such damage or destruction as described above, Landlord shall cause repairs and extortions to be

-17-

Table of Contents

made to the Leased Premises as hereafter provided, except that Landlord shall have no so obligation if this Lease is terminated by Landlord or Tenant as hereinafter provided.

(ii) If said damage to the Leased Premises, Building or equipment is of such nature or extent that, after commencement of the work more than sixty (60) consecutive days would be required (with normal work crews and hours) to repair and restore the part of the Leased Premises or Building that has been damaged, Landlord shall promptly so advise Tenant, and either party, for a period of ten (10) days from delivery of such notice in accordance with Section 30 hereof, shall have the right to terminate this Lease upon written notice to the other, as of the date specified in such notice, provided that such termination date shall be no later than thirty (30) days after Landlord becomes aware of such damage. If neither party elects to terminate this Lease, Landlord shall cause the Leased Premises to be restored to substantially their condition prior to the occurrence of said damage.

Other than the initial Improvements, if any, paid by Landlord, any alterations, additions, Improvements or fixtures that Tenant may have made or installed on the Leased Premises shall not be restored, unless Tenant, in a manner satisfactory to Landlord, assures payment in full of all costs that may be incurred in connection therewith. If there are any alterations, additions, Improvements or fixtures that have been installed by Tenant, and Tenant does not assure or agree to assure payment of the cost of restoration or repair of such alterations, additions, Improvements or fixtures, Landlord shall cause the Leased Premises to be restored to substantially the same condition that existed prior to the damage occurring, as if such alterations, additions, Improvements or fixtures had not then been made or installed to the Leased Premises, and such condition shall be determined with reference to the original construction drawings of the Leased Premises. The validity and effect of this Lease shall not be impaired in any way by, and Landlord shall have no liability to Tenant in connection with, any failure to cause repairs and restoration to be completed with respect to the Leased Premises or the Building within a period of one hundred twenty (120) consecutive days after commencement of work, even if Landlord has in good faith notified Tenant that the repair and restoration could be completed within such period, provided, however, that Landlord shall diligently commence and pursue such repair and restoration until completion in good and workmanlike manner.

(iii) If damage to the Leased Premises of the nature described in this Section 20A does not substantially impair Tenant's continued occupancy in the Leased Premises, the Basic Rent otherwise payable by Tenant hereunder shall be equitably abated or adjusted for the duration of such impairment. If Landlord and Tenant are unable to agree on the amount of the abatement of the Basic Rent, Tenant shall continue to pay the Basic Rent as set forth in Section 1A, and all Additional Rent, but the parties will submit their dispute to mediation and, if required, to arbitration pursuant to Section 33.

B. Notwithstanding anything contained herein, Landlord shall have no liability to Tenant for, and shall have no duty to repair, replace or restore, any damage whatsoever occurring as a result of leakage or seepage of water or any other liquid from any source whatsoever, or breakage of any water or sewage pipes, or as a result of odors, noise, or malfunction of any air conditioning, ventilating or sprinkler equipment unless such damage shall have been caused by Landlord's negligence or willful misconduct.

C. Tenant shall be responsible for insuring and repairing or replacing all of Tenant's equipment, fixtures and personal property located in the Leased Premises.

D. To the extent Tenant purchases a separate insurance policy with respect to any portion of the Leased Premises or anything contained therein, the provisions of Section 11A and 21D shall be applicable to such insurance policy and the proceeds thereof.

Hold Harmless; Public Liability Insurance; Waiver of Subrogation.

A. Subject to the provisions of Section 21D, Tenant covenants and agrees to indemnify and hold the Landlord and the Administrator, and any of their agents, employees or licensees harmless from any and all claims, demands, causes of action, losses, liabilities, damages and judgments, or charges of any kind including, without limitation, the cost of defending any action against it or them, together with any reasonable attorneys' fees incurred in connection therewith, or any other expenses, fees, or charges of any character or nature, arising directly or indirectly, out of or from or on account of: (i) any act or omission or negligence of Tenant, except nothing herein mentioned shall excuse or exculpate Landlord and/or the Administrator or their employees, agents or contractors from its or their negligence and, in such case, the indemnification and hold harmless provided herein shall not apply; and (ii) anything done or omitted to be done by the Tenant with regard to the Leased Premises or outside the scope of or in breach of, the terms of this Lease or which is the result of the Tenant's fraud, gross negligence or willful misconduct.

B. Neither Landlord nor the Administrator, shall be responsible or liable for damages at any time to Tenant, or to those claiming by, through or under Tenant, for any loss of life, bodily or personal injury, or damage to property or business, or for business interruption, that may be occasioned by or through the acts, omissions or negligence of any other persons, or any other tenants or occupants of any portion of the Building and Lot.

C. Tenant shall, at its own expense, keep in force public liability insurance (including a contractual liability insurance endorsement sufficient to cover indemnification) with such underwriters acceptable to Landlord and naming Tenant, the Landlord, and the Administrator as insured parties against claims for bodily injury, death or property damage on an occurrence basis with minimum limits of $1,000,000.00 for each occurrence. Said policy or policies of insurance or certificates thereof shall have attached an endorsement that such policy shall not be canceled without at least thirty (30) days prior written notice to Landlord and that no act or omission of Tenant shall invalidate the interest of Landlord under said insurance. Prior to occupancy of the Leased Premises and thereafter on the date on which such policy is required to be renewed, Tenant shall provide Landlord with evidence of such policy or policies of such insurance, or certificates thereof.

D. Landlord and Tenant hereby release each other from any and all liability or responsibility to the other or anyone claiming through or under them by way of subrogation or otherwise for any loss or damage to property covered by any fire and extended coverage insurance then in force, even if such fire or other casualty shall have been caused by the fault or negligence of the other party, or anyone for whom such party may be responsible; provided, however, that this release shall be applicable and in force and effect only to the extent of and with respect to any loss or damage occurring during such time as the policy or policies of insurance covering said loss shall contain a provision to the effect that this release shall not adversely affect or impair said insurance or prejudice the right of the insured to recover thereunder. If at any time the fire insurance carriers issuing fire insurance policies to Landlord or Tenant shall require an additional premium for the inclusion of such or similar provisions, the party whose insurance carrier has demanded the premium (the "Notifying Party") shall give the other party hereto notice thereof. In such event and if the other party requests, the Notifying Party shall require the inclusion of such or similar provisions by its fire insurance carrier, and such requesting party shall reimburse the Notifying Party for such additional premium for the remainder of the term of this Lease. If at any time any such insurance carriers shall not include such or similar provisions in any fire or extended coverage insurance policy, then, as to loss covered by that policy, the release set forth in this Section 21D shall be deemed of no further force or effect. The party whose policy no longer contains such provision shall notify the other party that the provision is no longer included in the policy,

-19-

Table of Contents

but the failure or delay in giving such notice shall not affect such termination of the release set forth in this Section 21D. During any period while the foregoing waivers are in effect, the party hereto as to whom such waivers are in effect shall look solely to the proceeds of such policies to compensate itself for any loss occasioned by fire or other casualty which is an insured risk under such policies.

Tenant agrees, from time to time as may be requested by Landlord, to execute, acknowledge and deliver to Landlord within fifteen (15) days after the receipt of the request, all or any of the following: (i) an estoppel letter certifying to such party as Landlord reasonably may designate, including any mortgagee, that this Lease is in full force and effect and has not been amended, modified or superseded, that Tenant has accepted the Leased Premises and is in possession thereof, that Tenant has no defense, offsets or counterclaims hereunder or otherwise against Landlord with respect to this Lease or the Leased Premises, and Landlord is not in default hereunder (or if any of the foregoing not be the case, specifying in reasonable detail the extent and nature thereof), that Tenant has no knowledge of any pledge or assignment of this Lease or rentals hereunder, that rent is accruing under this Lease but has not been paid more than one month in advance and the date to which rent has been paid; and (ii) any other instrument as any mortgagee of the condominium unit in which Leased Premises or any other person having any interest therein may reasonably request to be executed by Tenant; provided, however, that the rights of Tenant as provided for by this Lease are not materially affected by Tenant's execution of any such other instrument.

23. Subordination and Attornment.

A. This Lease and the estate, interest and rights hereby created are subordinate to any mortgage now or hereafter constituted upon the condominium unit in which the Leased Premises are located, or any estate or interest therein, and to all renewals, modifications, consolidations, replacements and extensions thereof as well as any substitutions therefore. The subordination provided herein is self-operative and does not require the execution of any document or instrument by Landlord, Tenant or the holder of any such mortgage. In the event that any person, firm, corporation or other entity acquires the right to possession or use and enjoyment of the Leased Premises (including any mortgagee or holder of any estate or interest having priority over this Lease), and if such person, firm, corporation, or other entity so requests, Tenant shall attorn to and become the tenant for the balance of the Lease Term of such person, firm, corporation or other entity, upon the same terms and conditions as are set forth herein.

B. Tenant, if requested by Landlord, shall execute any such instruments in recordable form as may be required by Landlord in order to confirm or effect the subordination of this Lease in accordance with the terms of this Section.

24. Assignment and Subletting.

A. Tenant shall not assign this Lease, sublet, or transfer all or any part of the Leased Premises, or permit the same to be occupied or used by anyone other than Tenant or its employees without Landlord's prior written consent, which consent shall not be unreasonably withheld. Tenant shall not pledge, mortgage, or otherwise transfer or encumbers this Lease without the prior written consent of Landlord, which consent may be withheld in Landlord's sole discretion. Without limiting the generality of the foregoing, Tenant acknowledges and agrees that it will be reasonable for Landlord to withhold its consent if: (i) the reputation, financial responsibility, or business of a proposed assignee or subtenant is deemed to be unsatisfactory in Landlord's reasonable opinion; (ii) Landlord reasonably deems assignee's or sub-tenant's business not to be consonant with that of other tenants in the Building; (iii) the intended use of the Leased Premises by the proposed assignee or subtenant conflicts with any commitment made by Landlord to any other tenant in the Building; (iv) the proposed rental rate is lower than the then current rate at which similar space in the Building is being offered by Landlord; (v) Landlord elects to require an assignment of this Lease or any sublease as described in Section C (ii) below; or (vi) Tenant is in default hereunder beyond all applicable grace and cure periods.

C. Within thirty (30) days from receipt of such request that includes the information described in Section B above, (i) Landlord shall grant or refuse its consent to the proposed assignment; and/or (ii) Landlord shall require Tenant and Tenant agrees to execute and assignment of this Lease or a sublease of Tenant’s interest hereunder to Landlord or its designee upon the same terms and conditions as are contained herein, together with an assignment of Tenant’s interest as sublessor in any such proposed sublease, including an assignment of any payment made or agreed to be made by the assignee or subtenant in excess of the rental and other charges due under this Lease, whether such premium be in the form of an increased monthly or annual rental, a lump sum payment, or any other form, provided that if Landlord proceeds in accordance with (ii) above, Tenant shall have no further responsibility hereunder in connection with the portion of the Leased Premises subject to such assignment or sublease.

D. Each assignee or transferee, hereunder shall assume and be deemed to have assumed the duties and obligations of Tenant under this Lease and shall be and remain liable jointly and severally ("solidariamente") with Tenant for all payments and for the due performance of all terms, covenants, conditions and provisions herein contained on Tenant's part to be observed and performed. No assignment shall be binding upon Landlord unless the assignee shall deliver to Landlord an instrument containing a covenant of assumption by the assignee with the same force and effect as if assignee had signed this Lease as Tenant, which instrument shall be approved by Landlord's legal counsel. The failure or refusal of assignee to execute the same shall not release said assignee from its obligations and responsibilities to Landlord as set forth herein.

E. Notwithstanding anything contained herein, Tenant shall not enter into any lease, sublease, license, concession or other agreement for the use, occupancy or utilization of the Leased Premises, or any portion thereof, that provides for a rental or other payment for such use, occupancy or utilization, based in whole or in part, on the income or profits derived by any person from the lease, use, occupancy or utilization of the Leased Premises (other than an amount based on a fixed percentage or percentages of receipts or sales). Any such purported lease, sublease, license, concession or other agreement shall be void and ineffective as a conveyance of any right or interest in the possession, use or occupancy of any part of the Leased Premises.

F. Any consent by Landlord hereunder shall not constitute a waiver of strict future compliance by Tenant of the provisions of this Section 24 or a release of Tenant from the full performance by Tenant of any of the terms, covenants, provisions, or conditions contained in this Lease.

G. If (i) without Landlord's consent described in Section A above, Tenant assigns this Lease; (ii) if the Leased Premises or any part thereof is occupied by anybody other than Tenant; or (iii) Landlord consents to such an assignment and an Event of Default (as hereinafter defined) has occurred and is continuing, Landlord at its option, may elect to collect rent from the assignee, subtenant or occupant of the Leased Premises, whereupon Landlord shall apply the net amount collected to any rent payable hereunder, but no such assignment, subletting, occupancy or collection shall be deemed to constitute a waiver of the provisions of this Section 24 or Landlord's acceptance of the assignee, subtenant or occupant as Tenant.

(iii) Terminate the Lease Term by giving written notice thereof to Tenant and, upon the giving of such notice, the Lease Term and the estate hereby granted shall expire and terminate with the same force and effect as though the date of such notice was the date hereinbefore fixed for the expiration of the Lease Term, and all rights of Tenant hereunder shall expire and terminate, but Tenant shall remain liable as hereinafter provided; or

(iv) Exercise any other rights and remedies available to Landlord at law or in equity.

B.

Landlord shall not be required to accept any tenant offered by Tenant or observe any instruction given by Tenant about such reletting, or do any act or exercise any care or diligence with respect to such reletting.

termination, Landlord may at any time thereafter elect to terminate this Lease for such previous breach.

E. In the event of any expiration or termination of this Lease or repossession of the Leased Premises or any part thereof by reason of an occurrence of an Event of Default, Landlord has not elected to accelerate rent pursuant to Section 26(A)(i), Tenant shall pay to Landlord the Basic Rent, Additional Rent and other sums required to be paid by Tenant to and including the date of such expiration, termination, or repossession; and, thereafter, Tenant shall, until the end of what would have been the outstanding lease term in the absence of such expiration, termination or repossession, and whether or not the Leased Premises or any part thereof shall have been relet, be liable to Landlord for, and shall pay to Landlord, the Basic Rent, Additional Rent and other sums that would be payable under this Lease by Tenant in the absence of such expiration, termination or repossession, less the net proceeds, if any, of any reletting effected for the account of Tenant pursuant to Section 26C, after deducting from such proceeds all of Landlord's expenses in connection with such reletting (including, without limitation, all related repossession costs, brokerage commissions, legal expenses, attorneys' fees, employees' expenses, alteration costs and expenses of preparation for such reletting). Tenant shall pay such current damages on the days on which the Basic Rent would have been payable under this Lease in the absence of such expiration, termination or repossession, and Landlord shall be entitled to recover the same from Tenant on each such day.

No waiver by Landlord of any breach by Tenant of any of Tenant's obligations, agreements or covenants herein shall be a waiver of any subsequent breach or of any obligation, agreement or covenant, nor shall any forbearance by Landlord to seek a remedy for any breach by Tenant be a waiver by Landlord of any rights and remedies with respect to such or any subsequent breach.

29. Severability.
