Notwithstanding the above and except as otherwise specifically provided in Exhibit C , Landlord shall, at its sole cost and expense, make any additions or changes to the Premises as may be required to bring the Premises into compliance with laws, statutes, ordinances and governmental rules, regulations or requirements in effect at the commencement date of this lease. 6 8. ALTERATIONS Tenant shall not make or suffer to be made any alteration, addition or improvement to or of the Premises or any part thereof (collectively referred to herein as "alterations") without (i) the prior written consent of Landlord (provided that no prior consent shall be required in the case of non- structural improvements costing less than $2,500) and (ii) a valid building permit issued by the appropriate governmental authority. Any alteration made by Tenant (excluding moveable furniture and trade fixtures which have not become an integral part of the building) shall at once become a part of the Premises and belong to Landlord. Without limiting the foregoing, all heating, lighting, electrical (including all wiring, conduit, outlets, drops, buss ducts, main and sub-panels), air conditioning, partitioning, drapery and carpet installations made by Tenant, regardless of how attached to the Premises, together with all other alterations that have become an integral part of the building of which the Premises are a part, shall be and become part of the Premises and belong to Landlord upon installation and shall not be deemed trade fixtures, and shall remain upon and be surrendered with the Premises at the termination of this lease. Any alteration by Tenant shall be made by Tenant at its sole risk, cost and expense. Alterations requiring Landlord's consent shall be made only after Landlord's written approval of any contractor or person selected by Tenant for that purpose. Upon the expiration or sooner termination of the term, Landlord may, at its sole option, require Tenant, at Tenant's sole cost and expense, to promptly both remove any such alteration made by Tenant and Tenant shall repair any damage to the Premises caused by such removal. Any movable furniture and equipment or trade fixtures remaining on the Premises at the expiration or other termination of the term shall become the property of Landlord unless promptly removed by Tenant. If during the term any alteration, addition or change of the Premises is required by law, regulation, ordinance or order of any public authority, Tenant, at its sole cost and expense, shall promptly make the same; provided that as to any such required capital improvement having a useful life of more than one year and which is not required by reason of Tenant's specific use of the Premises, Landlord shall make such capital improvement and Tenant shall pay to Landlord, as additional rent and in cash, the fraction of the cost of such capital improvement equal to the remaining term of this lease over the useful life of such capital improvement. If during the term any alteration or change to the Common Area (or to the Project or building in which the Premises is 7 located and it being, in Landlord's judgment, impractical for the affected tenants to individually make such alterations, additions or changes) is required by law, regulation, ordinance or order of any public or quasi-public authority, the cost of such alteration or change shall be a Common Area Charge and Tenant shall pay its percentage share of said costs to Landlord as provided in paragraph 16. 9. REPAIR AND MAINTENANCE By entry hereunder Tenant accepts the Premises as being in good and sanitary order, condition and repair (excepting only "punch list" items). Except as expressly provided below, Tenant shall at its sole cost keep and maintain the entire Premises and every part thereof including, without limitation, the windows, window frames, plate glass, glazing, truck doors, doors and all door hardware, the interior walls and partitions, lighting and the electrical and plumbing systems. Tenant shall also repair and maintain the heating and air conditioning systems (unless Landlord has elected to keep and maintain the heating and air conditioning systems as provided below) which shall include, without limitation, a periodic maintenance agreement with a reputable and licensed heating and air conditioning service company. If Tenant's use of the heating and air conditioning systems is limited to normal business hours (8 a.m. to 6 p.m.), such agreement shall provide for service at least as often as every sixty days; if Tenant's use of the heating or air conditioning systems extends beyond such normal business hours, this service shall be as often as may be required by Landlord; and in any event such service shall meet all warranty enforcement requirements of such equipment and comply with all manufacturer recommended maintenance. Landlord may elect, at its option, to keep and maintain the heating and air conditioning systems of the Premises and in such event, Tenant shall pay to Landlord upon demand the full cost of such maintenance and of repairs to such systems. To the full extent that it may do so, Landlord agrees to pass on to Tenant all applicable warranties with respect to items that Tenant is obligated to repair and maintain. Subject to the provisions of paragraph 17, Landlord shall keep and maintain the roof and structural elements of the buildings constituting the Project, and Common Area, in good order and repair. As used herein, "roof" is defined as the building's roofing membrane and tiles, and "structural elements" is defined as the building's foundation, slab-on-grade, columns, shear walls, floor trusses, metal deck and concrete fill, and the roof beams, purlins and roof plywood. Tenant waives all rights under and benefits of California Civil Code Sections 1932(1), 1941 and 1942 and under any 8 similar law, statute or ordinance now or hereafter in effect. The cost of the repairs and maintenance which are the obligation of Landlord hereunder shall be a Common Area Charge and Tenant shall pay its percentage share of such costs to Landlord as provided in paragraph 16; provided, however, that if Landlord replaces the entire roof of the building containing the Premises during the term, the Landlord shall bear the cost thereof and no part thereof shall be included in a Common Area Charge, and provided, further, that if any repairs or maintenance is required because of an act or omission of Tenant, or its agents, employees or invitees, Tenant shall pay to Landlord upon demand the full costs of such repair or maintenance. 10. LIENS Tenant shall keep the Premises and the Project free from any liens arising out of any work performed, materials furnished or obligations incurred by Tenant. In the event that Tenant shall not, within ten (10) days following the imposition of such lien, cause the same to be released of record, Landlord shall have, in addition to all other remedies provided herein and by law, the right, but no obligation, to cause the same to be released by such means as it shall deem proper, including payment of the claim giving rise to such lien. All sums paid by Landlord for such purpose, and all expenses incurred by it in connection therewith, shall be payable to Landlord by Tenant on demand with interest at the rate of eighteen percent (18%) per annum or the maximum rate permitted by law, whichever is less. Landlord shall have the right at all times to post and keep posted on the Premises any notices permitted or required by law, or which Landlord shall deem proper for the protection of Landlord, the Premises and the Project and any other party having an interest therein, from mechanics' and materialmen's liens and like liens. Tenant shall give Landlord at least fifteen (15) days' prior notice of the date of commencement of any construction on the Premises in order to permit the posting of such notices. 11. INSURANCE Tenant, At it's sole cost and expense, shall keep in force during the term (i) public liability insurance with limits of at least $2,000,000 per occurrence for injuries to or death of persons occurring in, on or about the Premises or the Project and property damage insurance with limits of at least $2,000,000 per occurrence and (iii) Worker's Compensation insurance as required by the State of California. All such policies shall be primary and shall provide that said insurance shall not be canceled or reduced except upon at 9 least thirty (30) days' prior written notice to Landlord. Further, Tenant's public liability insurance shall name Landlord as Additional Insured using ISO Bureau Form G109 or G112001 (or a successor form); shall contain cross-liability endorsements; and shall be issued by an insurance company admitted to transact business in the State of California. Landlord agrees to pay on demand up to $25.00 for the Additional Insured Endorsement. Tenant shall, prior to the commencement of the term, provide landlord with a completed Certificate of Insurance using Acord Form 25, a blank copy of which is attached to this lease. Tenant agrees to increase the coverages or otherwise comply with changes in connection with said public liability, property damage and Workers Compensation insurance as Landlord or Landlord's lender may from time to time require. Landlord shall obtain and keep in force a policy or policies of insurance covering loss or damage to the project, in the amount of the full replacement value thereof, providing protection against those perils included within the classification of "all risk" insurance, with increased cost of reconstruction and contingent liability (including demolition) and flood and/or earthquake insurance if available, plus a policy of rental income insurance in the amount of 100% of twelve (12) months' rent (including sums paid as additional rent) and such other insurance as Landlord or Landlord's lender may from time to time require. The cost of all such insurance purchased by Landlord, plus any charges for deferred payment of premiums and any deductible paid by Landlord, shall be Common Area Charges and Tenant shall pay its percentage share of such costs as provided in paragraph 16. If insurance costs are increased due to Tenant's use of the Premises, then tenant shall pay to Landlord upon demand the full cost of such increase. Landlord and Tenant hereby mutually waive any and all rights of recovery against one another for real or personal property loss or damage occurring to the Premises, the Project, or any part thereof, or any personal property therein, from perils insured against under fire and extended insurance and any other property insurance policies existing for the benefit of the respective parties so long as such insurance permits waiver of liability and contains a waiver of subrogation without additional premiums. If additional premiums must be paid, Tenant shall pay such additional premiums necessary to obtain such waiver. A copy of the Waiver of Subrogation in favor of Landlord shall be attached to the Tenant's completed Acord Form 25. 10 Notwithstanding anything hereinabove contained, Tenant shall be responsible for carrying, and shall pay the cost of, any casualty insurance as Tenant deems appropriate with respect to any Tenant's personal property and fixtures and any tenant improvements not the property of Landlord. 12. UTILITIES AND SERVICES Tenant shall pay for all water, gas, light, heat, power, electricity, telephone, trash pick-up, sewer charges and all other services supplied to or consumed on the Premises. Landlord shall install separate meters for interior gas, electricity and water. The cost of any utility or service not separately metered or billed to the premises shall be a Common Area Charge and Tenant shall pay its percentage share of such cost to Landlord as provided in paragraph 16. In addition, the cost of all utilities and services supplied to the Common Area shall be a Common Area Charge and Tenant shall pay its percentage share of such cost to Landlord as provided in paragraph 16. If Tenant's use of any such utility or service is materially in excess of the average furnished to the other tenants of the Project, and such utility or service is not separately metered, then Tenant shall pay to Landlord upon demand the full cost of such excess, or Landlord may cause such utility or service to be separately metered, in which case Tenant shall pay the full cost of such utility or service and reimburse Landlord upon demand for the cost of installing the separate meter. Landlord shall not be liable for, and Tenant shall not be entitled to, any abatement or reduction of rent by reason of the failure by any person or entity to furnish any of the foregoing utilities or services when such failure is caused by any cause beyond the reasonable control of Landlord. 13. TAXES AND OTHER CHARGES All real estate taxes and assessments and other taxes, fees and charges of every kind or nature levied or assessed against the Project or any part thereof during the term by any federal, state, county, regional, municipal or other governmental or quasi-public authority shall be a Common Area Charge and payable by Tenant as set forth in paragraph 16. By way of illustration and not limitation, "other taxes, fees, and charges" as used herein include any and all taxes payable by Landlord (other than state and federal personal or corporate income taxes measured by the 11 net income of Landlord from all sources, and premium taxes), whether or not now customary or within the contemplation of the parties hereto, (i) upon, allocable to, or measured by the rent payable hereunder, including, without limitation, any gross income or excise tax levied by the local, state or federal government with respect to the receipt of such rent, (ii) upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the premises or any part thereof, (iii) upon or measured by the value of Tenant's personal property or leasehold improvements located in the Premises, (iv) upon this transaction or any document to which Tenant is a party creating or transferring an interest or estate in the Premises, (v) upon or with respect to parking or the number of persons employed in or about the Project, and (vi) any tax, license, franchise fee or other imposition upon Landlord which is otherwise measured by or based in whole or in part upon the Project or any portion thereof. If Landlord contests any such tax, fee or charge, the cost and expense incurred by Landlord thereby shall also be a Common Area Charge and payable by Tenant as set forth in paragraph 16. In the event the premises and any improvements installed therein by Tenant or Landlord are valued by the assessor disproportionately higher than those of other tenants in the building or project or in the event alterations or improvements are made to the Premises, Tenant's percentage share of such taxes, assessments , fees and/or charges shall be adjusted upward accordingly and Tenant agrees to pay such readjusted share. Such determination shall be made by Landlord from the respective valuations assigned in the assessors work sheet or such other information as may be reasonably available and Landlord's determination thereof shall be conclusive. Tenant at its cost shall have the right at any time to seek a reduction in the assessed valuation of the Premises or the Project or to contest any real property taxes, assessments, fees or other taxes that are to be paid by Tenant; provided, however, that any such contest or proceeding shall be at Tenant's sole cost and expense and provided further that Tenant shall hold Landlord and the Premises and the Project harmless therefrom. Landlord shall not be required to join in any proceeding or contest brought by Tenant unless the provisions of any law require that the proceeding or contest be brought by or in the name of Landlord or any owner of the Premises. In that case Landlord shall cooperate and join in the proceeding or contest or permit it to be brought in Landlord's name as long as Landlord is not required to bear any cost. If Tenant seeks to reduce or contest any such tax, assessment, fee or other charge and if requested by Tenant, Landlord agrees to pay such tax, assessment, fee or charge under protest and to 12 otherwise deal with the appropriate authority in a manner consistent with Tenant's contest or proceeding and the applicable rules, regulations or procedures of such authority. In the event Tenant obtains any refund attributable to the Premises, such refund shall belong to Tenant. Tenant agrees to pay, before delinquency, any and all taxes levied or assessed during the term hereof upon Tenant's equipment, furniture, fixtures and other personal property located in the Premises, including carpeting and other property installed by Tenant notwithstanding that such carpeting or other property has become part of the Premises. 14. ENTRY BY LANDLORD Landlord reserves, and shall at all reasonable times have, the right to enter the Premises (i) to inspect the Premises, (ii) to supply services to be provided by Landlord hereunder, (iii) to show the Premises to prospective purchasers, lenders or tenants and to put 'for sale' or 'for lease' signs thereon, (iv) to post notices required or allowed by this lease or by law, (v) to alter, improve or repair the Premises and any portion of the Project, and (vi) to erect scaffolding and other necessary structures in or through the Premises or the Project where reasonably required by the character of the work to be performed. Landlord shall not be liable in any manner for any inconvenience, disturbance, loss of business, nuisance or other damage arising from Landlord's entry and acts pursuant to this paragraph and Tenant shall not be entitled to any abatement or reduction of rent if Landlord exercises any rights reserved in this paragraph. For each of the foregoing purposes, Landlord shall at all times have and retain a key with which to unlock all of the doors in, on and about the Premises (excluding Tenants vaults, safes and similar areas designated in writing by Tenant in advance), and Landlord shall have the right to use any and all means which Landlord may deem proper to open said doors in an emergency in order to obtain entry to the Premises. Any entry by Landlord to the Premises pursuant to this paragraph shall not under any circumstances be construed or deemed to be a forcible or unlawful entry into or a detainer of the Premises or an eviction, actual or constructive, of Tenant from the Premises or any portion thereof. Landlord shall also have the right at any time to change the name, number or designation by which the Project is commonly known. 15. COMMON AREA Subject to the terms and conditions of this lease and such reasonable rules and regulations as Landlord may from time to time prescribe, Tenant and Tenant's employees, 13 invitees and customers shall, in common with other occupants of the Project in which the Premises are located, and their respective employees, invitees and customers and others entitled to the use thereof, have the nonexclusive right to use the access roads, parking areas and facilities provided and designated by Landlord for the general use and convenience of the occupants of the Project, which areas and facilities are referred to herein as "Common Area." This right shall terminate upon the termination of this lease. Landlord reserves the right from time to time to make changes in the shape, size, location, amount and extent of the Common Area. Landlord further reserves the right to promulgate such reasonable rules and regulations relating to the use of the Common Area, and any part thereof, as Landlord may deem appropriate for the best interests of the occupants of the Project. The rules and regulations shall be binding upon Tenant upon delivery of a copy of them to Tenant and Tenant shall abide by them and cooperate in their observance. Such rules and regulations may be amended by Landlord from time to time, with or without advance notice. Tenant shall have the use of one hundred sixty-eight (168) parking spaces in the Common Area as designated in Exhibit A. Tenant shall not label or otherwise mark its assigned parking spaces without the prior written approval of Landlord, provided that such approval shall not unreasonably be withheld. Tenant shall be solely responsible for policing its assigned parking spaces with respect to unauthorized use by others. Tenant shall not at any time park or permit the parking of Tenant's trucks or other vehicles, or the trucks or other vehicles of others, adjacent to loading areas so as to interfere in any way with the use of such areas; nor shall Tenant at any time park or permit the parking of Tenant's vehicles or trucks, or the vehicles or trucks of Tenant's suppliers or others, in any portion of the Common Area not designated by Landlord for such use by Tenant. Tenant shall not park or permit any inoperative vehicle or equipment to be parked on any portion of the Common Area. Landlord shall operate, manage and maintain the Common Area. The manner in which the Common Area shall be operated, managed and maintained and the expenditures for such operation, management and maintenance shall be at the sole discretion of Landlord, provided that such maintenance shall be in a manner equal to that usually provided for other first class buildings in the same general area as the Project. The cost of such maintenance, operation and management, including but not limited to landscaping, repair of paving, parking lots and sidewalks, security services and salaries and employee benefits (including union benefits) of on-site 14 and accounting personnel engaged in such maintenance and operations management, shall be a Common Area Charge and Tenant shall pay to Landlord its percentage share of such costs as provided in paragraph 16. 16. COMMON AREA CHARGES Tenant shall pay to Landlord, as additional rent, an amount equal to 28.63% of the total Common Area Charges as defined in this lease. Tenant further agrees that Common Area Charges shall include an additional 5% of the actual expenditures for the aggregate of all other Common Area Charges in order to compensate Landlord for accounting and processing services. Tenant's percentage share of Common Area Charges shall be paid as follows: At or prior to the commencement of the term and to the commencement of each calendar year of the term, Landlord shall deliver to Tenant a written estimate of total Common Area Charges during the balance of the calendar year in which the term commences and each succeeding calendar year, respectively. Tenant shall pay, as additional rent, on the first day of each month during the calendar year (or portion thereof covered by such estimate) its percentage monthly share of Common Area Charges as shown on such estimate. Within thirty (30) days of the end of each calendar year and of the end of the term, Landlord shall deliver to Tenant a statement of the actual Common Area Charges incurred for the preceding year, or, in the case of a statement after the end of the term, covering the year in which the lease terminates. If such statement shows that Tenant has paid less than its actual percentage then Tenant shall on demand pay to Landlord the amount of such deficiency. If such statement shows that Tenant has paid more than its percentage share then Landlord shall, at its option, promptly refund such excess to Tenant or credit the amount thereof to the rent next becoming due from Tenant. Landlord reserves the right to revise any estimate of Common Area Charges if actual or projected Common Area Charges show an increase or decrease in excess of 10% from any earlier estimate for the same period. In such event, Landlord shall deliver the revised estimate to Tenant, together with an explanation of the reasons therefor, and Tenant shall revise its payments accordingly. Landlord's and Tenant's obligations with respect to adjustments at the expiration or earlier termination of this lease shall survive such termination. 17. DAMAGE BY FIRE; CASUALTY If the Premises or any part of the Project is damaged by fire or other casualty, Landlord shall promptly repair such damage if, in Landlord's judgement, such repair 15 can be made within one hundred twenty (120) days consistent with the laws and regulations of the state, federal, county and municipal authorities having jurisdiction, and this lease shall remain in full force and effect, provided that if there shall be damage to the Premises from any such cause, Tenant shall be entitled to a reduction of rent, as reasonably calculated by Landlord, while such repair is being made in the proportion that the area of the Premises rendered untenantable by such damage bears to the total area of the Premises. Tenant hereby waives the provisions of Sections 1932 (2) and 1933 (4) of the California Civil Code. If such repairs cannot, in Landlord's judgement, be made within one hundred twenty (120) days, Landlord shall have the option to either (i) repair such damage, this lease continuing in full force and effect but with the rent proportionately reduced upon the condition and as above provided, or (ii) give notice to Tenant at any time within thirty (30) days after the occurrence of such damage terminating this lease as of the date specified in such notice, which shall be not less than thirty (30) nor more than one hundred twenty (120) days after the giving of such notice. If such notice of termination is given, this lease and all interest of Tenant in the Premises shall terminate on the date specified in the notice and all payments of rent reduced by any proportionate reduction, shall be paid up to the date of such termination. Landlord shall refund to Tenant any rent previously paid for any period of time subsequent to the date of termination. If (i) the damage to the Premises renders more than fifty percent (50%) of the Premises untenantable, (ii) the damage is not due to the act or omission of Tenant, and (iii) Landlord has not completed the repairs within one hundred eighty (180) days from the date of occurrence of such damage, then Tenant may terminate this lease by giving notice to Landlord at any time within thirty (30) days after the end of said one hundred eighty (180) day period, said notice to specify a termination date of no later than sixty (60) days from the date of such notice. Notwithstanding any other provision of this lease, Landlord shall in no event be required to repair any injury or damage by fire or other cause whatsoever to, or make any repairs or replacements of, any paneling, decorations, movable partitions, trade of office fixtures or any other property of, or improvements installed on the Premises by, Tenant. Notwithstanding anything to the contrary contained in this paragraph 17: (i) Tenant shall not be entitled to any compensation or damages for loss of use of the whole or any part of the Premises and/or for any inconvenience or annoyance occasioned by such damage or from the repair, restoration or reconstruction thereof; (ii) in the event that the damage is due to any cause other than fire or other peril covered by extended coverage insurance, then Landlord may 16 elect to terminate this lease; (iii) should Landlord be delayed or prevented from repairing the damaged Premises within one year after the occurrence of such damage by act of God, war, governmental restriction, inability to produce necessary labor or materials or other causes beyond the reasonable control of Landlord, then Landlord shall be relieved of its obligation to make such repair or restoration and Tenant shall be released from its obligation under this lease as of the end of said one-year period. 18. INDEMNIFICATION Landlord shall not be liable to Tenant and Tenant hereby waives all claims against Landlord for any injury to or death of any person or damage to or destruction of property in or about the Premises or the Project by or from any cause whatsoever except the negligence of Landlord or its authorized representatives. Except as to injury to persons or damage to property the principal cause of which is the negligence of Landlord or its authorized representatives, Tenant shall hold Landlord harmless from and defend Landlord against any liability, loss, damage or expense, including attorney fees, arising out of any injury to or death of any person or damage to or destruction of property occurring in, on or about the Premises from any cause whatsoever. Tenant shall hold Landlord harmless from and defend Landlord against any liability, loss, damage or expense, including attorney fees, arising (i) out of the failure of Tenant to observe or comply with laws or other requirements as set forth in paragraph 7, (ii) by reason of Tenant's use, handling, storage or disposal of toxic or hazardous materials or waste, or (iii) by reason of any labor or services performed for, or materials used by or furnished to, Tenant or any contractor engaged by Tenant with respect to the Premises. The provisions of this paragraph 18 shall survive the expiration or termination, however caused, of this lease. 19. ASSIGNMENT AND SUBLETTING Tenant shall not voluntarily assign, encumber or otherwise transfer its interest in this lease or in the Premises, or sublease all or any part of the Premises, or allow any other person or entity to occupy or use all or any part of the Premises, without first complying with the terms of this paragraph 19 and without first obtaining Landlord's written consent. Any assignment, encumbrance or sublease made without complying with this paragraph 19 and without Landlord's written consent shall be void and, at Landlord's election, shall constitute a material default by Tenant. No consent to any assignment, encumbrance or sublease shall constitute a waiver of any provisions of this paragraph 19. 17 If Tenant desires to sublet or assign all or any portion of the Premises, Tenant shall give Landlord written notice thereof, specifying the projected commencement date of the proposed sublet or assignment (which date shall be not less than thirty (30) days or more than ninety (90) days after the date of such notice), the portions of the Premises proposed to be sublet or assigned, and the identity of the proposed assignee or subtenant. Tenant shall further provide Landlord with such other information concerning the proposed assignee or subtenant as requested by Landlord. In the case of any proposed assignment, or if the proposed sublet for all or any portion of the Premises is for a sublet term ending within the last twelve (12) months of the term of this lease, or if the proposed sublet is for more than 35% of the Premises, then Landlord shall have the right, exercisable by written notice to be delivered to Tenant within thirty (30) days of receipt of Tenant's notice, to terminate this lease as to the portion proposed to be assigned or sublet effective as of the date specified in Tenant's notice as the proposed commencement date of the assignment or sublease. If this lease is so terminated as to only a portion of the Premises, the monthly rent and other payments hereunder shall be adjusted on a pro rata basis based on the number of square feet retained by Tenant, and this lease as so amended shall continue in full force and effect, provided that Tenant shall have no further liability or obligation to Landlord with respect to such surrendered portion of the Premises (excepting obligations of Tenant arising prior to the effective date of such surrender and such obligations as expressly survive termination), and provided, further, that nothing herein shall affect Landlord's rights under paragraph 8 with respect to the surrendered protion of the Premises.) If Landlord does not elect to terminate this lease as provided above, or if Landlord did not have a right to terminate with respect to the proposed sublet, and Landlord consents in writing to the proposed assignment or sublet, Tenant shall be free to assign or sublet as specified in the notice to Landlord, subject to the following conditions: (i) any sublease shall be on the same terms set forth in the notice given to Landlord; (ii) no sublease shall be valid and no subtenant shall take possession of the sublet premises until an executed counterpart of such sublease has been delivered to Landlord; (iii) no subtenant shall have a further right to sublet; (iv) one-half of any sums or other economic consideration received by Tenant as a result of such assignment or sublet (except rental or other payments received which are attributable to the amortization over the term of this lease of the cost of leasehold improvements constructed for such assignee or subtenant, and brokerage fees) whether denominated rentals or otherwise, which exceed, in the aggregate, the total sums which Tenant is 18 obligated to pay Landlord under this lease (prorated to reflect obligations allocable to that portion of the Premises subject to such sublease), shall be payable to Landlord as additional rent under this lease without affecting or reducing any other obligation of Tenant hereunder; and (v) no sublet or assignment shall release Tenant of Tenant's obligation or alter the primary liability of Tenant to pay the rent and to perform all other obligations to be performed by Tenant hereunder. The acceptance of rent by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof. Consent to one assignment or sublet shall not be deemed consent to any subsequent assignment or sublet. In the event of default by any assignee of Tenant or any successor of Tenant in the performance of any of the terms hereof, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against such assignee or successor. Landlord may consent to subsequent assignments or sublets of this lease or amendments or modifications to this lease with assignees of Tenant, without notifying Tenant, or any successor of Tenant, and without obtaining its or their consent thereto and such action shall not relieve Tenant of liability under this lease. Notwithstanding the above provisions of this paragraph 19, Tenant may, without obtaining the consent of Landlord and without Landlord having the right to terminate this lease as set forth above, assign or sublease the whole or any part of the Premises to any corporation or other entity which acquires or is acquired by LTX Corporation or which results from a merger or consolidation with LTX Corporation or which either controls or is controlled by LTX Corporation or which is controlled by any of the foregoing, provided that (i) Tenant shall continue to be fully obligated for the timely performance of all the terms, covenants, agreements and conditions of this lease and (ii) such assignee or subtenant agrees in writing to be subject to and governed by all of the terms, covenants, agreements and conditions of this lease and such agreement by assignee or subtenant is promptly given to Tenant. Tenant shall give Landlord written notice of any such assignment or sublease as provided above in this paragraph 19, and any such assignment or subletting shall be subject to the conditions for other assignments and sublettings set forth above. No interest of Tenant in this lease shall be assignable by operation of law (including, without limitation, the transfer of this lease by testacy or intestacy). Each of the following acts shall be considered an involuntary assignment: (i) if Tenant is or becomes bankrupt or insolvent, 19 makes an assignment for the benefits of creditors or institutes, a proceeding under the Bankruptcy Act in which Tenant is the bankrupt; or, if Tenant is a partnership or consist of more than one person or entity, if any partner of the partnership or other person or entity is or becomes bankrupt or insolvent, or makes an assignment for the benefit of creditors; (ii) if a writ of attachment or execution is levied on this lease; or (iii) if, in any proceeding or action to which Tenant is a party, a receiver is appointed with authority to take possession of the Premises. An involuntary assignment shall constitute a default by Tenant and Landlord shall have the right to elect to terminate this lease, in which case this lease shall not be treated as an asset of Tenant. Tenant immediately and irrevocably assigns to Landlord, as security for Tenant's obligations under this lease, all rent from any subletting of all or a part of the Premises a permitted by this lease, and Landlord, as assignee and as attorney-in-fact for Tenant, or a receiver for Tenant appointed on Landlord's application, may collect such rent and apply it toward Tenant's obligations under this lease: except that, until the occurrence of an act of default by Tenant, Tenant shall have the right to collect such rent, subject to promptly forwarding to Landlord any portion thereof to which Landlord is entitled pursuant to this paragraph 19. 20. DEFAULT The occurrence of any of the following shall constitute a default by Tenant: (i) failure to pay any rent or other sum payable hereunder within three (3) business days of written notice from Landlord of failure to make such payment when due; (ii) abandonment of the Premises; or (iii) failure to perform any other term, covenant or condition of this lease if the failure to perform is not cured within thirty (30) days after notice thereof has been given to Tenant (provided that if such default cannot reasonably be cured within thirty (30) days, Tenant shall not be in default of this lease if Tenant commences to cure the default within the thirty (30) day period and diligently and in good faith continues to cure the default). The notice referred to in (iii) above shall specify the alleged default and the applicable lease provision and shall demand that Tenant perform the provisions of this lease within the applicable period of time and no such notice shall be deemed a forfeiture or termination of this lease unless Landlord so elects in the notice. No notice shall be required in the event of failure to pay any rent or other sum or in the event of abandonment or vacation of the Premises. 20 In the event of a default by Tenant, then Landlord, in addition to any other rights and remedies at law or in equity, shall have the right either to terminate Tenant's rights to possession of the Premises and thereby terminate this lease or, from time to time and without termination this lease, relet the Premises or any part thereof for the account and in the name of Tenant for such term and on such terms and conditions as Landlord in its sole discretion may deem advisable, with the right to make alterations and repairs to the Premises. Should Landlord elect to keep this lease in full force and effect, Landlord shall have the right to enforce all of Landlord's rights and remedies under this lease, including but not limited to the right to recover the installments of monthly rent and Common Area Charges as they become due, and to relet the Premises. If Landlord relets the Premises, then Tenant shall pay to Landlord, as soon as ascertained, the costs and expenses incurred by Landlord in such reletting and in making alterations and repairs. Rentals received by landlords from such reletting shall be applied (i) to the payment of any indebtness due hereunder, other than monthly rent, from Tenant to Landlord; (ii) to the payment of the coast of any repairs necessary to return to the Premises to good conditions, normal wear and tear excepted, including the cost of alterations and the cost of storing any of Tenant's property left on the Premises ant the time of the reletting; and (iii) to the payment of monthly rent due and unpaid hereunder. The residue, if any, shall be held by Landlord and applied in payment of future rent or damages in the event of termination as the same may become due and payable hereunder and the balance, if any at the end of the term of this lease, shall be paid to Tenant. Should the monthly rent and Common Area Charges received from time to time from such reletting during any month be less than agreed to be paid during that month by Tenant hereunder, Tenant shall pay such deficiency to Landlord. Such deficiency shall be calculated and paid monthly. No such reletting of the Premises by Landlord shall be construed as election on its part to terminate this lease unless a notice of such intention is given to Tenant or unless the termination hereof is decreed by a court of competent jurisdiction. Notwithstanding any such reletting without termination, Landlord may at any time thereafter elect to terminate this lease for such previous breach, provided it has not been cured. Should Landlord at any time terminate this lease for any breach in addition to any other remedy it may have, it shall have the immediate right of entry and may remove all persons and property from the Premises and, in addi- 21 tion to all its other rights and remedies, shall be entitled to recover from Tenant all damages it may incur by reason of such breach, including the cost of recovering the Premises and including (i) all amounts that would have fallen due as rent between the time of termination of this lease and the time of the judgement or other award plus interest on the balance at the rate of twelve percent (12%) per year, but less the avails of relettings and attornments; (ii) the worth at the time of the judgement or other award of the amount by which the unpaid rent for the balance of the term exceeds the amount of such rental loss that Tenant proves could be reasonably avoided; (iii) any other amount necessary to compensate Landlord for all the detriment proximately cause 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. "Worth" as used in this provision is computed by discounting the total at the discount rate of the Federal Reserve Bank of San Francisco at the time of the judgment or award plus one percent (1%). Property removed from the Premises may be stored in a public or private warehouse or elsewhere at the sole cost and expense of Tenant. In the event that Tenant shall not immediately pay the cost of storage of such property after the same has been stored for a period of thirty (30) days or more, Landlord may sell any or all there at a public or private sale in such a manner and at such times and places at Landlord in its sole discretion may deem proper, without notice to or demand upon Tenant. Any proof by Tenant under subparagraphs (2) and (3) of Section 1951.2(a) of the California Civil Code of the amount of rental loss that could be reasonably avoided shall be made in the following manner: Landlord and Tenant shall each select a licensed real estate broker in the business of renting property of the same type and use as the Premises in the same geographical vicinity. Such two real estate and brokers shall select a third licensed real estate broker, and the three licensed real estate brokers so selected shall determine the amount of the rental loss that could be reasonably avoided for the balance of the term after the time of award. The decision of the majority of said licensed real estate brokers shall be final and binding upon the parties hereto. 21. LANDLORD'S RIGHT TO CURE TENANT'S DEFAULT Landlord, at any time after Tenant commits a default, can cure the default at Tenant's cost. If Landlord at any time, by reason of Tenant's default, pays any sum or does any act that requires the payment of any sum, the sum paid by Landlord shall be due immediately from Tenant to Landlord at the time the sum is paid, and if paid at 22 a later date shall bear interest at the rate of eighteen percent (18%) per annum or the maximum rate permitted by law, whichever is less, from the date the sum is paid by Landlord until Landlord is reimbursed by Tenant. This sum, together with interest on it, shall be additional rent. 22. EMINENT DOMAIN If all or any part of the Premises shall be taken by any public or quasi-public authority under the power of eminent domain or conveyance in lieu thereof, this lease shall terminate as to any portion of the Premises so taken or conveyed on the date when title vests in the condemnor, and Landlord shall be entitled to any and all payment, income, rent, award of any interest therein whatsoever which may be paid or made in connection with such taking or conveyance. Tenant shall have no claim against Landlord or otherwise for the value of any unexpired term of this lease. Notwithstanding the foregoing, any compensation for depreciation to and cost of removal of equipment and fixtures shall be and remain the property of Tenant. Each party waives the provisions of Section 1265.130 of the Code of Civil Procedure (which Section allows either party to petition the Superior Court to terminate this lease in the event or a partial taking of the premises). If any action or proceeding is commenced for such taking of the Premises or any portion thereof or of any other space in the Project, or if Landlord is advised in writing by any entity or body having the right or power of condemnation of its intention to condemn the Premises or any portion thereof or of any other space in the Project, and Landlord shall decide to discontinue the use and operation of the Project or decide to demolish, alter or rebuild the Project, then Landlord shall have the right to terminate this lease by giving Tenant written notice thereof within sixty (60) days of the date of receipt of said written advice or the commencement of said action or proceeding. Such termination shall take place on the last day of the calendar month next following the month in which such notice is given or the date on which title shall vest in the condemnor, whichever occurs first. In the event a partial taking, or conveyance in lieu thereof, of the Premises and thirty-five percent (35%) or more of the number of square feet in the Premises or in Tenant's designated parking area are taken then Tenant may terminate this lease. Any election by Tenant to so terminate shall be by written notice given to Landlord within sixty 23 (60) days from the date of such taking or conveyance and shall be effective on the last day of the calendar month next following the month in which such notice is given or the date on which title shall vest in the condemnor. whichever occurs first. If a portion of the Premises be taken by power of eminent domain or conveyance in lieu thereof and neither Landlord nor Tenant shall terminate this lease then this lease shall continue in full force and effect as to the part of the Premises not so taken or conveyed and all payments of rent shall be apportioned as of the date of such taking or conveyance so that thereafter the amounts to be paid by Tenant shall be in the ratio that the area of the portion of the Premises not so taken bears to the total area of the Premises prior to such taking. 23. NOTICE AND COVENANT TO SURRENDER On the last day of the term or on the effective date of any earlier termination, Tenant shall surrender to Landlord the Premises and all of Tenant's improvements and alterations in their condition existing as of the commencement of the term, with all originally painted interior walls washed, or repainted if marked or damaged interior vinyl covered walls cleaned and repaired or replaced if marked or damaged, all carpets shampooed and cleaned, the air conditioning and heating systems serviced and repaired by a reputable and licensed service firm (unless Landlord has elected to maintain such system pursuant to paragraph 9 above) and all floors cleaned and waxed; all to the reasonable satisfaction of Landlord. Tenant shall remove all of Tenant's personal property and trade fixtures, together with improvements or alterations that Tenant is obligated to remove pursuant to the provisions of paragraph 8, from the Premises, and all such property not removed shall be deemed abandoned. If the Premises are not surrendered as required in this paragraph, Tenant shall indemnify Landlord against all loss and liability resulting from the failure by Tenant in so surrendering the Premises, including, without limitation, any claim made by any succeeding tenant, or losses to Landlord due to lost opportunities to lease to succeeding tenants. It is agreed between Landlord and Tenant that the provisions of this paragraph shall survive termination of this lease. 24 24. TENANT'S QUITCLAIM At the expiration or earlier termination of this lease, Tenant shall execute, acknowledge and deliver to Landlord, within ten (10) business days after written demand from Landlord to Tenant, any quitclaim deed or other document required by any reputable title company, licensed to operate in the State of California, to remove the cloud or encumbrance created by this lease from the real property of which the Premises are a part. This obligation shall survive said expiration or termination. 25. HOLDING OVER Any holding over after the expiration or termination of this lease (with the written consent of Landlord delivered to Tenant) shall be construed to be a tenancy from month to month at the monthly rent, as adjusted, in effect on the date of such expiration or termination. All provisions of this lease, except those pertaining to the term and any option to extend, shall apply to the month to month tenancy. The provisions of this paragraph are in addition to, and do not affect, Landlord's right to re-entry or other rights hereunder or provided by law. If Tenant shall retain possession of the Premises or any part thereof without Landlord's consent following the expiration or sooner termination of this lease for any reason, then Tenant shall pay to Landlord for each day of such retention double the amount of the daily rental in effect during the last month prior to the date of such expiration or termination. Tenant shall also indemnify and hold Landlord harmless from any loss or liability resulting from delay by Tenant in surrendering the Premises including, without limitation, any claims made by any succeeding tenant founded on such delay. Acceptance of rent by Landlord following expiration or termination shall not constitute a renewal of this lease, and nothing contained in this paragraph shall waive Landlord's right of re-entry or any other right. Tenant shall be only a Tenant at sufferance, whether or not Landlord accepts any rent from Tenant, while Tenant is holding over without Landlord's written consent. 26. SUBORDINATION Landlord shall deliver to Tenant promptly after execution hereof a non-disturbance agreement from each and every lender holding a mortgage or deed of trust encumbering all or any portion of the Premises and which is prior and superior to this lease and in existence as of the date of execution hereof, which non-disturbance agreement shall 25 provide that such lender agrees that Tenant's possession and quiet enjoyment of the Premises shall not be disturbed by such lender so long as Tenant performs all of its obligations under this lease, and which shall otherwise be in form reasonably satisfactor to Tenant and such lender. In the event that any lender requires that this lease be subordinated to any encumbrance recorded after the date of this lease affecting the Premises, this lease shall be subordinate to that encumbrance and Tenant agrees to execute in writing an agreement effecting such subordination, provided Landlord first obtains from such lender a written agreement that provides in substance that as long as Tenant performs its obligations under this lease, no foreclosure of, deed given in lieu of foreclosure of, or sale under the encumbrance, shall affect Tenant's rights under this lease. 27. CERTIFICATE OR ESTOPPEL Each party shall, within ten (10) days after request therefor, execute and deliver to the other party, in recordable form, a certificate stating that the lease is unmodified and in full force and effect, or in full force and effect as modified and stating the modifications. The certificate shall also state the amount of the monthly rent, the date to which monthly rent has been paid in advance, the amount of the security deposit and/or prepaid monthly rent, and, if the request is made by Landlord, shall include such other items as Landlord or Landlord's lender may reasonably request. Failure to deliver such certificate within such time shall constitute a conclusive acknowledgment by the party failing to deliver the certificate that the lease is in full force and effect and has not been modified except as may be represented by the party requesting the certificate. Any such certificate requested by Landlord may be conclusively relied upon by any prospective purchaser or encumbrancer of the Premises or Project. Further, within ten (10) days following written request made from time to time by Landlord, Tenant shall furnish to Landlord current quarterly financial reports of Tenant. 28. SALE BY LANDLORD In the event the original Landlord hereunder, or any successor owner of the Project or Premises, shall sell or convey the Project or Premises, all liabilities and obligations on the part of the original Landlord, or such successor owner, under this lease accruing thereafter shall terminate, and thereupon all such liabilities and obligations shall be binding upon the new owner. Tenant agrees to attorn 26 to such new owner and to look solely to such new owner for performance of any and all such liabilities and obligations arising under this lease. 29. ATTORNMENT TO LENDER OR THIRD PARTY In the event the interest of Landlord in the land and buildings in which the Premises are located (whether such interest of Landlord is a fee title interest or a leasehold interest) is encumbered by deed of trust, and such interest is acquired by a lender or any other third party through judicial foreclosure or by exercise of a power of sale at private trustee's foreclosure sale and to recognize such purchaser as the Landlord under this lease. 30. DEFAULT BY LANDLORD Landlord shall not be in default unless Landlord fails to perform obligations required of Landlord within a reasonable time, but in no event earlier than thirty (30) days after written notice by Tenant to Landlord and to the holder of any first mortgage or deed of trust covering the Premises specifying wherein Landlord has failed to perform such obligations; provided, however, that if the nature of Landlord's obligations is such that more than thirty (30) day period and thereafter diligently prosecutes the same to completion. If Landlord is in default of this lease, and as a consequence Tenant recovers a money judgement against Landlord, the judgement shall be satisfied only out of the proceeds of sale received on execution of the judgement and levy against the right, title and interest of Landlord in the Project of which the Premises are a part, and out of rent or other income from such real property receivable by Landlord or out of the consideration received by Landlord from the sale or other disposition of all or any part of Landlord's right, title and interest in the Project of which the Premises are a part. Neither Landlord nor any of the partners comprising the partnership designated as Landlord shall be personally liable for any deficiency. 31. CONSTRUCTION CHANGES It is understood that the description of the Premises and the Location of ductwork, plumbing and other facilities therein are subject to such minor changes as Landlord's architect determines to be desirable in 27 the course of construction of the Premises and/or the improvements constructed or being constructed thereon, and no such changes, or any changes in plans for any other portions of the Project, shall affect this lease or entitle Tenant to any reduction of rent hereunder or result in any liability of Landlord to Tenant. 32. MEASUREMENT OF PREMISES Tenant understands and agrees that any reference to square footage of the Premises is approximate only and includes all interior partitions and columns, one-half of the partitions separating the Premises from the rest of the Project, and any outside entry overhang, if applicable. Tenant waives any claim against Landlord regarding the accuracy of any such measurement and agrees that there shall not be any adjustment in monthly rent or Common Area Charges or other amounts payable hereunder by reason of inaccuracies in such measurement. 33. EXHIBITS AND ATTACHMENTS All exhibits and attachments to this lease are a part hereof. 34. ATTORNEY FEES If either party commences an action against the other party arising out of or in connection with this lease, the prevailing party shall be entitled to have and recover from the losing party all expenses of litigation, including, without limitation, travel expenses, attorney fees, expert witness fees, trial and appellate court costs, and deposition and transcript expenses. If either party becomes a party to any litigation concerning this lease, the Premises, or the Project by reason of any act or omission of the other party or its authorized representative, the party that causes the other party to become involved in the litigation shall be liable to that party for all expenses of litigation, including, without limitation, travel expenses, attorney fees, expert witness fees, trial and appellate court costs, and deposition and transcript expenses. 35. SURRENDER The voluntary or other surrender of this lease or the Premises by Tenant, or a mutual cancellation of this lease, shall not work a merger, and at the option of Landlord shall either terminate all or any existing subleases or subtenancies or operate as an assignment to Landlord of all or any such subleases or subtenancies. 28 36. WAIVER No delay or omission in the exercise of any right or remedy of Landlord on any default by Tenant shall impair such right or remedy or be construed as a waiver. The receipt and acceptance by Landlord of delinquent rent or other payments shall not constitute a waiver of any other default and acceptance of partial payments shall not be construed as a waiver of the balance of such payment due. No act or conduct of Landlord, including, without limitation, the acceptance of the keys to the Premises, shall constitute an acceptance of the surrender of the Premises by Tenant before the expiration of the term. Only a written notice from Landlord to Tenant shall constitute acceptance of the surrender of the Premises and accomplish a termination of this lease. Landlord's consent to or approval of any act by Tenant requiring Landlord's consent or approval shall not be deemed to waive or render unnecessary Landlord's consent to or approval of any subsequent act by Tenant. Any waiver by Landlord of any default must be in writing and shall not a waiver of any other default concerning the same or any other provision of this lease. 37. EASEMENTS; AIRSPACE RIGHTS Landlord reserves the right to alter the boundaries of the Project and grant easements and dedicate for public use portions of the Project without Tenant's consent, provided that no such grant or dedication shall interfere with Tenant's use of the Premises or otherwise cause Tenant to incur cost or expense. From time to time, and upon Landlord's demand, Tenant shall execute, acknowledge and deliver to Landlord, or in accordance with Landlord's instructions, and any all documents, instruments, maps or plans necessary to effectuate Tenant's covenants hereunder. This lease confers no rights either with regard to the subsurface of the land on which the Premises are located or with regard to airspace above the ceiling of the Premises. Tenant agrees that no diminution or shutting off of light or view by an structure which is or may be erected (whether or not by Landlord) on property adjacent to the building of which the Premises are a part or to property adjacent thereto, shall in any way affect this lease, or entitle Tenant to any reduction of rent, or result in any liability of Landlord to Tenant. 29 38. RULES AND REGULATIONS Landlord shall have the right from time to time to promulgate reasonable rules and regulations for the safety, care and cleanliness of the Premises, the Project and the Common Area, or for the preservation of good order. On delivery of a copy of such rules and regulations to Tenant, Tenant shall comply with the rules and regulations, and a violation of any of them shall constitute a default by Tenant under this lease. If there is a conflict between the rules and regulations and any of the provisions of this lease, the provisions of this lease shall prevail. Landlord shall make all reasonable efforts to enforce the rules and regulations uniformly against all tenants in the Project, and no such rules and regulations shall require Tenant to pay additional rent under this lease. Such rules and regulations may be amended by Landlord from time to time with or without advance notice. 39. NOTICES All notices, demands, requests, consents and other communications which may be given or are required to be given by either party to the other shall be in writing and shall be sufficiently made and delivered if personally served or if sent by United States first class mail, postage prepaid. All such communications from Landlord to Tenant shall be addressed to Tenant at the Premises. All such communications by Tenant to Landlord shall be sent to Landlord at its offices at 710 Lakeway, Suite 200, Sunnyvale, California 94086. Either party may change its address by notifying the other of such change. Each such communication shall be deemed received on the date of the personal service or mailing thereof in the manner herein provided, as the case may be. 40. NAME Tenant shall not use the name of the Project for any purpose other than as the address of the business conducted by Tenant in the Premises without the prior written consent of Landlord. 41. GOVERNING LAW; SEVERABILITY This lease shall in all respects be governed by and construed in accordance with the laws of the State of California. If any provision of this lease shall be invalid, unenforceable or ineffective for any reason whatsoever, all other provisions hereof shall be and remain in full force and effect. 30 42. DEFINITIONS As used in this lease, the following words and phrases shall have the following meanings: AUTHORIZED REPRESENTATIVE: any officer, agent, employee or independent contractor retained or employed by either party, acting within authority given him by that party. ENCUMBRANCE: any deed or trust, mortgage or other written security device or agreement affecting the Premises or the Project that constitutes security for the payment of a debt or performance of an obligation, and the note or obligation secured by such deed of trust, mortgage or other written security device or agreement. LENDER: the beneficiary, mortgagee or other holder of an encumbrance, as defined above LIEN: a charge imposed on the Premises by someone other than Landlord, by which the Premises are made security for the performance of an act. Most of the liens referred to in this lease are mechanic's liens. MAINTENANCE: repairs, replacement, repainting and cleaning. PERSON: one or more human beings, or legal entities or other artificial persons, including, without limitation, partnerships, corporations, trusts, estates, associations and any combination of human beings and legal entities. PROVISION: any term, agreement, covenant, condition, clause, qualification, restriction, reservation or other stipulation in the lease that defines or otherwise controls, establishes or limits the performance required or permitted by either party. RENT: monthly rent, additional rent, Common Area Charges, and all other amounts payable by Tenant to Landlord required by this lease or arising by subsequent actions of the parties made pursuant to this lease. Words used in any gender include other genders. If there be more than one Tenant the obligations of Tenant hereunder are joint and several. All provisions, whether covenants or conditions, on the part of Tenant shall be deemed to be 31 both covenants and condtions. The paragraph headings are for convenience of reference only and shall have no effect upon the construction or interpretation of any provision hereof. 43. TIME Time is of the essence of this lease and of each and all of its provisions. 44. EXAMINATION OF LEASE Submission of this lease for examination or signature by Tenant does not constitute a reservation or option for a lease, and this lease is not effective until its execution and delivery by both Landlord and Tenant. 45. INTEREST ON PAST DUE OBLIGATIONS; LATE CHARGES Any amount due from Tenant to Landlord hereunder which is not paid when due shall bear interest at the rate of ten percent (10%) per annum from when due until paid, unless otherwise specifically provided herein, but the payment of such interest shall not excuse or cure any default by Tenant under this lease. In additon, Tenant acknowledges that late payment by Tenant to Landlord of monthly rent, or of Tenant's monthly Common Area Charge, or of any other amount due Landlord from Tenant, will cause Landlord to incur costs not contemplated by this lease, the exact amount of such costs being extremely difficult and impractical to fix. Such costs include, without limitation, processing and accounting charges, and late charges that may be imposed on Landlord, e.g., by the terms of any encumbrance and note secured by any encumbrance covering the Premises. Therefore, if any such payment due from Tenant is not received by Landlord when due, Tenant shall pay to Landlored an additional sum of five percent (5%) of the overdue payment 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. Acceptance of any late charge shall not constitute a waiver of Tenant's default with respect to the overdue amount, nor prevent Landlord from exercising any of the other rights and remedies available to Landlord. No notice to Tenant of failure to pay shall be required prior to the imposition of such interest and/or late charge, and any notice period provided for in paragraph 20 shall not affect the imposition of such interest and/or late charge. 32 46. ENTIRE AGREEMENT This lease, including any exhibits and attachments, constitutes the entire agreement between Landlord and Tenant relative to the Premises and this lease and the exhibits and attachments may be altered, amended or revoked only by an instrument in writing signed by both Landlord and Tenant. Landlord and Tenant agree hereby that all prior or contemporaneous oral agreements between and among themselves or their agents or representatives relative to the leasing of the Premises are merged in or revoked by this lease. 47. CORPORATE AUTHORITY Each individual executing this lease on behalf of Tenant represents and warrants that he is duly authorized to execute and deliver this lease on behalf of Tenant and that this lease is binding upon Tenant in accordance with its terms. Tenant shall deliver to Landlord, within twenty (20) days of the execution of this lease, either a copy of a duly adopted resolution of the Board of Directors of Tenant approving this lease (which copy shall be certified by Tenant's president or secretary as correct and in full force and effect) or the certificate of Tenant's secretary setting forth the authority of the person signing this lease on behalf of Tenant in such form as shall be reasonably acceptable to Landlord. 48. RECORDING Upon request by Tenant, Landlord shall record this lease or a short form memorandum hereof in form reasonably satisfactory to Tenant. Tenant agrees to concurrently on termination or expiration of the term to execute and record a release, quitclaim or other document reasonably requested by Landlord. 49. REAL ESTATE BROKERS Each party represents that it has not had dealing with any real estate broker, finder or other person with respect to this lease in any manner, except Dick Treakle. Each party shall hold harmless the other party from all damages resulting from any claims that may be asserted against the other party by any broker, finder or other person with whom the other party has or purportedly has dealt. 33 50. SUBLETTING DURING THE FIRST TWO YEARS OF THE TERM Notwithstanding anything to the contrary in paragraph 19 above, Tenant may, during the first two years of the term only and without Landlord's prior consent, sublet up to thirty-five percent (35%) of the Premises for a term ending on or before the last day of the twenty-fourth month of the term for uses authorized under paragraph 1 above (plus for storage); provided, however, that Tenant shall give written notice to Landlord of any such sublet, and such sublet shall otherwise be subject to the requirement and conditions for sublets generally as set forth in paragraph 19 (except that Landlord shall not be entitled to receive any portion of the amounts received by Tenant from any such sublet). IN WITNESS WHEREOF, Landlord and Tenant have executed and delivered this lease on the date first above written. LANDLORD: TENANT: CALIFORNIA SECOND, LTD. LTX CORPORATION By /s/ By /s/ Adrian E.
