See Rider Attached (b) It is hereby agreed that commencing January 1 of the calendar year following the Commencement Date, Tenant shall pay to Landlord as Additional Rent during the balance of the term hereof an estimate of Tenant's Pro Rata Share of Operating Expenses for the calendar year in excess of the Base Operating Expenses as reasonably estimated by Landlord, payable monthly, at the rate of one twelfth (1/12) thereof, on the same date and at the same place Base Rent is payable, with an adjustment to be made between the parties at a later date as hereinafter provided. Landlord shall deliver to Tenant, as soon as practicable following the end of any calendar year, an estimate of the Operating Expenses for the new calendar year (the "Budget Sheet"). Until receipt of the Budget Sheet, Tenant shall continue to pay its monthly Tenant's Pro Rata Share of Operating Expenses based upon the estimate for the preceding calendar year. To the extent that the Budget Sheet reflects an estimate of Tenant's Pro Rata Share of Operating Expenses for the new calendar year greater than the amount actually paid to the date of receipt of the Budget Sheet for the new calendar year, Tenant shall pay such amount to Landlord within thirty (30) days of receipt of the Budget Sheet. Upon receipt of the Budget Sheet, Tenant shall thereafter pay the amount of its Tenant's Pro Rata Share of Operating Expenses as set forth in the Budget Sheet. As soon as practicable following the end of any calendar year, but not later than May 1st, Landlord shall submit to Tenant a statement in reasonable detail describing the computations of the Operating Expenses setting forth the exact amount of Tenant's Pro Rata Share of Operating Expenses for the calendar year just completed (the "Statement"), and the difference, if any, between the actual Tenant's Pro Rata Share of Operating Expenses for the calendar year just completed and the estimated amount of Tenant's Pro Rata share of Operating Expenses paid by Tenant to Landlord. Notwithstanding the foregoing, Landlord's failure to deliver the Statement to Tenant on or before May 1st, shall in no way serve as a waiver of Landlord's rights under this Paragraph. To the extent that the actual Tenant's Pro Rata 4 Share of Operating Expenses for the period covered by the Statement is higher than the estimated Tenant's Pro Rata Share of Operating Expenses which Tenant previously paid during the calendar year just completed, Tenant shall also pay to Landlord such balance within thirty (30) days following receipt of the Statement from Landlord. To the extent that the actual Tenant's Pro Rata Share of Operating Expenses for the period covered by the Statement is less than the estimated Tenant's Pro Rata Share of Operating Expenses which Tenant previously paid during the calendar year just completed, Landlord shall credit the excess against any sums then owing or next becoming due from Tenant under the Lease. (c) If the Lease term hereunder covers a period of less than a full calendar year during the first or last calendar years of the term hereof, Tenant's Pro Rata Share of Operating Expenses for such partial year shall be calculated by proportionately reducing the Base Operating Expenses to reflect the number of months in such year during which Tenant leased the Premises (the "Adjusted Base Operating Expenses"). The Adjusted Base Operating Expenses shall then be compared with the actual Operating Expenses and actual Real Estate Taxes for said partial year to determine the amount, if any, of any increases in the actual Operating Expenses for such partial year over the Adjusted Base Operating Expenses. Tenant shall pay Tenant's Pro Rata Share of any such increases within ten (10) days following receipt of notice thereof. (d) Tenant shall have the right at its own expense and at a reasonable time (after written notice to Landlord) within six (6) months after receipt of the Statement to audit Landlord's books relevant to the Additional Rent due under this Paragraph 5. In the event Tenant does not audit Landlord's books and deliver the result thereof to Landlord within said six (6) month period, the terms and amounts set forth in the Statement shall be deemed conclusive and final and Tenant shall have no further right to adjustment. In the event Tenant's examination reveals that an error has been made in Landlord's determination of Tenant's Pro Rata Share of Operating Expenses and Landlord agrees with such determination, then the amount of such adjustment shall be payable by Landlord or Tenant, to the other party as the case may be. In the event Tenant's examination reveals an error has been made in Landlord's determination of Tenant's Pro Rata Share of Operating Expenses, and Landlord disagrees with the results thereof, Landlord shall have thirty (30) days to obtain an audit from an accountant of its choice to determine Tenant's Pro Rata Share of Operating Expenses. In the event Landlord's accountant and Tenant's accountant are unable to reconcile their audits, both accountants shall mutually agree upon a third accountant, whose determination of Tenant's Pro Rata Share of Operating Expenses shall be conclusive. In the event the amount of error by Landlord is determined to be seven and one half percent (7.5%) or more, the reasonable costs of the three audits made pursuant to this subparagraph shall be paid by Landlord. In the event the amount of error by Landlord is determined to be less than ten percent (10%), the reasonable costs of the three audits made pursuant to this subparagraph shall be paid to Tenant. (e) Landlord's failure during the Lease term to prepare and deliver any statement or bills, or Landlord's failure to make a demand under this Paragraph or under any other provision of this Lease shall not in any way be deemed to be a waiver of, or cause Landlord to forfeit or surrender its rights to collect any items of Additional Rent which may have become due pursuant to this Paragraph during the term of this Lease. Tenant's liability for all Additional Rent due under this Paragraph 5 shall survive the expiration or earlier termination of this Lease. 6.

Should any such liens be filed or recorded against the Premises, Building or Building Complex with respect to work done for or materials supplied to or on behalf of Tenant or should any action affecting the title thereto be commenced, Tenant shall cause such liens to be released of record within ten (10) days after notice thereof. If Tenant desires to contest any such claim of lien, Tenant shall nonetheless cause such lien to be released of record by the posting of adequate security with a court of competent 9 jurisdiction if provided by applicable law or statute of the state where the Premises are located. If Tenant shall be in default in paying any charge for which such a mechanic's lien or suit to foreclose such a lien has been re-recorded or filed and shall not have caused the lien to be released as aforesaid, Landlord may (but without being required to do so) pay such lien or claim and any costs associated therewith, and the amount so paid, together with interest at the Interest Rate and reasonable attorneys' fees incurred in connection therewith, shall be immediately due and payable from Tenant to Landlord as Additional Rent. 13. DAMAGE TO PROPERTY, INJURY TO PERSONS: (a) Tenant, for itself and its legal representatives, successors and assigns, as a material part of the consideration to be rendered to Landlord under this Lease, hereby waives all claims of liability against Landlord and Tenant, for itself and its legal representatives, successors and assigns, hereby indemnifies and agrees to hold harmless Landlord, its agents, employees, contractors, legal representatives, successors and assigns, from any and all claims of liability for any injury or damage to any person or property whatsoever occurring in, on or about the Premises or the Building Complex or any part thereof, to the extent such injury or damage is caused by the negligence, fault or omission of Tenant, its agents, contractors, employees, licensees or invitees. Tenant further agrees to indemnify and to hold Landlord harmless from and against any and all claims arising from any breach or default in the performance of any obligation on Tenant's part to be performed under the terms of this Lease, or arising from any act or negligence of Tenant, or any of its agents, contractors, employees, licensees or invitees. Such indemnities shall include by way of example, but not limitation, all costs, reasonable attorneys' fees, expenses and liabilities incurred in or about any such claim action or proceeding. (b) Landlord shall not be liable to Tenant for any damage by or from any act or negligence of any company-tenant or other occupant of the Building Complex, or by any owner or occupant of adjoining or contiguous property. Landlord shall not be liable for any injury or damage to persons or property resulting in whole or in part from the criminal activities of others. To the extent not covered by normal fire and extended coverage insurance, Tenant agrees to pay for all damage to the Building Complex, as well as all damage to persons or property of other tenants or occupants thereof, caused by the misuse, neglect, act, omission or negligence of Tenant or any of its agents, contractors, employees, licensees or invitees. (c) Tenant hereby releases Landlord, its agents and employees, from liability occasioned by the act, omission or negligence of Landlord, its agents, servants and employees, for the following: (i) any damage to property entrusted to Landlord, its agents or employees; (ii) loss or damage to any property occurring by theft or otherwise; (iii) any injury or damage to persons or property resulting from fire, explosion, falling plaster, steam, gas, electricity, water or rain which may leak from any part of the Building Complex or from the pipes, appliances or plumbing works therein or from the roof, street or subsurface or from any other place or resulting from dampness, or any other cause whatsoever; (iv) interference with the lights, view or other incorporeal hereditaments; provided, however, nothing contained herein shall be construed to relieve Landlord from liability for any personal injury resulting from its gross negligence. Tenant shall give prompt notice to Landlord in case of fire or accidents in or about the Premises or the Building or of defects therein or in the fixtures or equipment located therein. (d) In case any claim, demand, action or proceeding is made or brought against either party, its agents or employees, by reason of any obligation on either party's part to be performed under the terms of this Lease, or arising from any act or negligence of either party, its agents or employees, or which gives rise to either party's obligation to indemnify the other, the prevailing party shall be responsible for all costs and expenses, including but not limited to reasonable attorneys' fees incurred in defending or prosecution of the same, as applicable. 14. INSURANCE: (a) Landlord agrees to carry and maintain the following insurance during the term of this Lease and any extension hereof: general public liability insurance against claims for personal injury, including death and property damage in or about the Premises and the Building or the Building Complex (excluding Tenant's Property), such insurance to be in an amount not less than One Million Dollars ($1,000,000.00) each occurrence, 10 Two Million Dollars ($2,000,000.00) aggregate. Such insurance may expressly exclude property paid for by tenants or paid for by Landlord for which tenants have reimbursed Landlord located in, or constituting a part of the Building or the Building Complex. Such insurance shall afford coverage for damages resulting from (a) fire, (b) perils covered by extended coverage insurance, and (c) explosion of steam and pressure boilers and similar apparatus located in the Building or the Building Complex. Landlord may carry such other additional insurance coverage as Landlord or Landlord's mortgage deems appropriate including coverage for loss of rents. All such insurance shall be procured from a responsible insurance company or companies authorized to do business in the State where the Premises are located. (b) Tenant shall, at its own cost, at all times during the term of this Lease and any extensions hereof, procure and [illegible] extended coverage on Tenant's Property and [illegible] equal to full replacement cost thereof, and [illegible] including coverage for bodily injury, property [illegible] contractual liability exclusions deleted), product [illegible] liability, owner's protective liability, host liquor [illegible] damage with the following limits of liability [illegible] occurrence combined single limit for bodily injury [illegible] Two Million Dollars ($2,000,000.00) aggregate [illegible] products and completed operations. All such [illegible] responsible insurance company or companies [illegible] the Premises are located, with general policyholder's [illegible] and a financial rating of not less than "XI" in the most current available Best's Insurance Reports, and shall be otherwise satisfactory to Landlord. All such policies shall name Landlord as an additional insured, and shall provide that the same may not be canceled or altered except upon thirty (30) days prior written notice to Landlord. All insurance maintained by Tenant shall be primary to any insurance provided by Landlord. If Tenant obtains any general liability insurance policy on a claims-made basis, Tenant shall provide continuous liability coverage for claims arising during the entire term of this Lease, regardless of when such claims are made, either by obtaining an endorsement providing for an unlimited extended reporting period in the event such policy is canceled or not renewed for any reason whatsoever or by obtaining new coverage with a retroactive date the same as or earlier than the expiration date of the canceled or expired policy. Tenant shall provide certificate(s) of such insurance to Landlord upon commencement of the Lease term and at least thirty (30) days prior to any annual renewal date thereof and upon request from time to time and such certificate(s) shall disclose that such insurance names Landlord as an additional insured, in addition to the other requirements set forth herein. The limits of such insurance shall not, under any circumstances, limit the liability of Tenant hereunder. (c) Each party agrees to use its best efforts to include in each of its policies insuring against loss, damage or destruction by fire or other casualty a waiver of the insurer's right of subrogation against the other party, or if such waiver should be unobtainable or unenforceable (i) an express agreement that such policy shall not be invalidated if the insured waives the right of recovery against any party responsible for a casualty covered by the policy before the casualty; or (ii) any other form of permission for the release of the other party. If such waiver, agreement or permission shall not be, or shall cease to be, obtainable without additional charge or at all, the insured party shall so notify the other party promptly after learning thereof. In such case, if the other party shall so elect and shall pay the insurer's additional charge therefor, such waiver, agreement or permission shall be included in the policy, or the other party shall be named as an additional insured in the policy. Each such policy which shall so name a party hereto as an additional insured shall contain, if obtainable, agreements by the insurer that the policy will not be canceled without at least thirty (30) days prior notice to both insureds and that the act or omission of one insured will not invalidate the policy as to the other insured. Any failure by either party, if named as an additional insured, promptly to endorse to the other of the other party, without recourse, any instrument for the payment of money under or with respect to the policy of which the other party is the owner or original or primary insured, shall be deemed a default under this Lease. (d) Each party hereby releases the other party with respect to any claim (including a claim for negligence) which it might otherwise have against the other party for loss, damage or destruction with respect to its property (including the Building, Building Complex, the Premises and rental value or business interruption) occurring during the term of this Lease to the extent to which it is insured under a policy or policies containing a waiver of subrogation or permission to release liability or naming the above party as an additional insured as provided above. 11 15. DAMAGE OR DESTRUCTION TO BUILDING: (a) In the event that the Premises or the Building are damaged by fire or other insured casualty and the insurance proceeds have been made available therefor by the holder or holders of any mortgages or deeds of trust covering the Building, the damage shall be repaired by and at the expense of Landlord to the extent of such insurance proceeds available therefor, provided such repairs and restoration can, in Landlord's reasonable opinion, be made within two hundred ten (210) days after the occurrence of such damage without the payment of overtime or other premiums, and until such repairs and restoration are completed, the Base Rent shall be abated in proportion to the part of the Premises which is unusable by Tenant in the conduct of its business (but there shall be no abatement of Base Rent by reason of any portion of the Premises being unusable for a period equal to one day or less). Landlord agrees to notify Tenant within forty-five (45) days after such casualty if it estimates that it will be unable to repair and restore the Premises within said two hundred ten (210) day period. Such notice shall set forth the approximate length of time Landlord estimates will be required to complete such repairs and restoration. Notwithstanding anything to the contrary contained herein, if Landlord cannot or estimates it cannot make such repairs and restoration within said two hundred ten (210) day period, then Tenant may, by written notice to Landlord cancel this Lease, provided such notice is given to Landlord within fifteen (15) days after Landlord notifies Tenant of the estimated time for completion of such repairs and restoration. Notwithstanding the preceding sentence, Tenant may not cancel this lease as hereinabove stated if the damage to the Premises or the Building is in whole or in part the result of the act, omission, fault or negligence of Tenant, its agents, contractors, employees, licensees or invitees. Except as provided in this Paragraph 15, there shall be no abatement of rent and no liability of Landlord by reason of any injury to or interference with Tenant's business or property arising from the making of any such repairs, alterations or improvements in or to the Building, Premises or fixtures, appurtenances and equipment, except for Landlord's negligence, Tenant understands that Landlord will not carry insurance of any kind on Tenant's Property, including furniture and furnishings, or on any fixtures or equipment removable by Tenant under the provisions of this Lease, or any improvement installed in the Premises by or on behalf of Tenant, and that Landlord shall not be obligated to repair any damage thereto or replace the same unless damage is due to negligence of Landlord. (b) In case the Building throughout shall be so injured or damaged, whether by fire or otherwise (though the Premises may not be affected, or if affected, can be repaired within said 210 days) that Landlord, within sixty (60) days after the happening of such injury, shall decide not to reconstruct or rebuild the Building, then notwithstanding anything contained herein to the contrary, upon notice in writing to that effect given by Landlord to Tenant within said sixty (60) days, Tenant shall pay the rent, properly apportioned up to date of such casualty, this Lease shall terminate from the date of delivery of said written notice, and both parties hereto shall be released and discharged from all further obligations hereunder (except those obligations which expressly survive termination of the Lease term). A total destruction of the Building shall automatically terminate this Lease. 16. CONDEMNATION: (a) If the whole of the Premises or so much thereof as to render the balance unusable by Tenant for the proper conduct of its business shall be taken under power of eminent domain or transferred under threat thereof, then this Lease, at the option of either Landlord or Tenant exercised by either party giving notice to the other of such election within thirty (30) days after such conveyance or taking possession, whichever is earlier, shall forthwith cease and terminate and the rent shall be duly apportioned as of the date of such taking or conveyance. No award for any partial or entire taking shall be apportioned and Tenant hereby assigns to Landlord any award which may be made in such taking or condemnation, together with any and all rights of Tenant now or hereafter arising in or to the same or any part thereof. Notwithstanding the foregoing, Tenant shall be entitled to seek, directly from the condemning authority, an award for its removable trade fixtures, equipment and personal property and relocation expenses, if any. In the event of a partial taking which does not result in a termination of this Lease, Base Rent shall be reduced in proportion to the reduction in the size of the Premises so taken and this Lease shall be modified accordingly. Promptly after obtaining knowledge thereof, Landlord or Tenant, as the case may be, shall notify the other of any pending or threatened condemnation or taking affecting the Premises or the Building. 12 (b) If all or any portion of the Premises shall be condemned or taken for governmental occupancy for a limited period, this Lease shall not terminate and Landlord shall be entitled to receive the entire amount of any such award or payment thereof as damages, rent or otherwise. Tenant hereby assigns to Landlord any award which may be made in such temporary taking, together with any and all rights of Tenant now or hereafter arising in or to the same or any part thereof. Tenant shall be entitled to receive an abatement of Base Rent in proportion to the reduction in the size of the Premises so taken. 17. ASSIGNMENT AND SUBLETTING: (a) Tenant shall not permit any part of the Premises to be used or occupied by any persons other than Tenant and its employees nor shall Tenant permit any part of the Premises to e used or occupied by any licensee or concessionaire or permit any persons other than Tenant, its employees and invitees, to be upon the Premises. Tenant shall not voluntarily, by operation of law, or otherwise, assign, transfer or encumber this Lease or any interest herein nor sublet or part with possession of all or any part of the Premises (any and all of which shall hereinafter be referred to as "Transfer") without Landlord's prior written consent, which will not be unreasonably withheld. Any Transfer without the prior written consent of Landlord shall constitute a default hereunder and shall be void ab initio and shall confer no rights upon any third party, notwithstanding Landlord's acceptance of rent payments from any purported transferee. Landlord's consent to any requested assignment of this Lease or subletting of all or any part of the Premises shall be subject to the following conditions: (1) such consent and resulting subletting or assignment shall not relieve Tenant of its primary obligations hereunder, including the obligation for payment of all rents due hereunder; (2) Landlord, at its option and from time to time, may collect the rent from the subtenant or assignee, and apply the net amount collected to the rent herein reserved, but no such collection shall be deemed an acceptance by Landlord of the subtenant or assignee as the tenant hereof, or a release of Tenant from further performance of covenants on the part of Tenant herein contained; (3) any such subtenant or assignee shall be a company or other entity of good repute, engaged in a business or profession compatible with and in keeping with the then standards of the Building and financially capable of performing its obligations with respect to the Premises; (4) such subtenant or assignee shall assume and agree to perform all of Tenant's obligations under this Lease insofar as they pertain to the space so sublet or assigned; and (5) Tenant is not in default of any term or condition of this lease at the time it requests Landlord's consent. (b) In the event of any Transfer of this Lease or all or any part of the Premises by Tenant, Landlord in addition to any rights contained herein, shall have the option, at its discretion, to collect and receive the excess of rent due to Tenant from any sublessee or assignee over the Base Rent due hereunder. Further, in the event of any Transfer of this Lease of all or any part of the Premises by Tenant without the prior written consent of Landlord, Landlord, in addition to any rights contained herein shall have the following options, at its discretion: (1) To give Tenant written notice of Landlord's intention to terminate this Lease on the date such notice is given or on any later date specified therein, whereupon, on the date specified in such notice, Tenant's right to possession of the Premises shall cease and this Lease shall thereupon be terminated, except as to any incompleted obligations of Tenant; or (2) To re-enter and take possession of the Premises or the part thereof subject to such Transfer, and to enforce all rights of Tenant, and receive and collect all rents and other payments due to Tenant, in accordance with such sublet or assignment of the Premises, or any part thereof, as if Landlord was the sublettor or assignor, and to do whatever Tenant is permitted to do pursuant to the terms of such sublease or assignment. 13 (c) The sale of all or a majority of the stock of Tenant, if Tenant is a corporation, or the sale of all or a majority of the ownership interest in Tenant, if Tenant is a partnership, or the sale of all or substantially all of the assets of Tenant shall constitute a Transfer for purposes of this Lease. (d) At the time of making a request for Landlord's consent to a Transfer and not less than ten (10) business days prior to the proposed effective date thereof, Tenant shall provide to Landlord such information as Landlord, its accountants and attorneys, shall reasonably require with respect to such proposed Transfer, including but not limited to name and address of the proposed transferee, description of business operations, financial information and certificate of corporate authority and good standing or partnership certificate, as applicable. Landlord must respond within ten (10) business days or it is deemed to have approved transferee. (e) Consent of Landlord to a Transfer shall not relieve Tenant from seeking consent to any subsequent Transfers. (f) Subletting or assignments by subtenants or assignees shall not be permitted under any circumstances, nor shall Tenant e permitted to assign this Lease or sublet all or part of the Premises during any period of time that all or any portion of the Base Rent is abated. Further, no option to renew or extend the term of this Lease or to lease additional space, if any, shall be exercisable by any subtenant or assignor. (g) All subleases or assignments shall be in writing and a copy thereof provided to Landlord within ten (10) days of its effective date. All subleases shall further contain an express provision that in the event of any default by Tenant under this Lease and upon notice thereof to the subtenant from Landlord, all rentals payable by the subtenant shall be paid directly to Landlord, for the Tenant's account, until subsequent notice from Landlord that such default has been cured. Notwithstanding the foregoing, receipt by Landlord of rent directly from the subtenant shall not be considered a waiver of the default on the part of Tenant, nor an acceptance of such subtenant. 18. ESTOPPEL CERTIFICATE: Tenant further agrees at any time and from time to time on or before ten (10) business days after written request by landlord, to execute, acknowledge and deliver to Landlord an estoppel certificate certifying (to the extent it believes the same to be true) that this Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as modified, and stating the modifications), that there have been no defaults thereunder by Landlord or Tenant (or if there have been defaults, setting forth the nature thereof), the date to which the rent and other charges have been paid, if any, that Tenant claims no present charge, lien, claim or offset against rent, the rent is not prepaid for more than one month in advance and such other matters as may be reasonably required by Landlord, Landlord's mortgagee, or any potential purchaser of the Building, it being intended that any such statement delivered pursuant to this Paragraph may be relied upon by any prospective purchaser of all or any portion of Landlord's interest herein, or a holder of any mortgage or deed of trust encumbering any portion of the Building Complex. Tenant's failure to deliver such statement within such time shall be a default under this Lease. Notwithstanding the foregoing, in the event that Tenant does not execute the statement required by this paragraph, Tenant hereby grants to Landlord a power of attorney coupled with an interest to act as Tenant's attorney in fact for the purpose of executing such statement or statements required by this Paragraph. 19. DEFAULT: (a) The following events (herein referred to as an "event of default") shall constitute a default by Tenant hereunder; (1) Tenant shall fail to pay when due any installment of Base Rent, Additional Rent or any other amounts payable hereunder, and continues for three (3) days after receipt of written notice from Landlord. (2) This Lease or the estate of Tenant hereunder shall be transferred to or pass to or devolve upon any other person or party in violation of the provisions of this Lease, except as permitted herein; 14 (3) This Lease or the Premises or any part thereof shall be taken upon execution or by other process of law directed against Tenant, or shall be taken upon or subject to any attachment at the instance of any creditor or claimant against Tenant, and said attachment shall not be discharged or disposed of within fifteen (15) days after the levy thereof; (4) Tenant shall file a petition in bankruptcy or insolvency or for reorganization or arrangement under the bankruptcy laws of the United States or under any insolvency act of any state, or shall voluntarily take advantage of any such law or act by answer or otherwise, or shall be dissolved or shall make an assignment for the benefit of creditors; (5) Involuntary proceedings under any such bankruptcy law or insolvency act or for the dissolution of Tenant shall be instituted against Tenant, or a receiver or trustee shall be appointed of all or substantially all of the property of Tenant, and such proceedings shall not be dismissed or such receivership or trusteeship vacated within thirty (30) days after such institution or appointment; (6) Tenant shall fail to take possession of the Premises within thirty (30) days of the Commencement Date; (7) Tenant shall fail to perform any of the other agreements, terms, covenants and conditions hereof on Tenant's part to be performed (other than the obligation to pay rent or any other charges payable hereunder), and such nonperformance shall continue for a period of fifteen (15) days after written notice thereof by Landlord to Tenant; provided, however, that if Tenant cannot reasonably cure such nonperformance within fifteen (15) days, Tenant shall not be in default if it commences cure within said fifteen (15) days and diligently pursues the same to completion, with completion occurring in all instances within sixty (60) days; (8) Tenant shall fail to obtain a release of any mechanic's lien, as required herein; (9) All or any substantial part of the personal property of Tenant is seized, subject to levy or attachment, or similarly repossessed or removed from the Premises. (b) Upon the occurrence of an event of default, Landlord shall have the right, at its election, then or at any time thereafter and while any such event of default shall continue, either; (1) To give Tenant written notice of Landlord's intention to terminate this Lease on the date such notice is given or on any later date specified therein, whereupon, on the date specified in such notice, Tenant's rights to possession of the Premises shall cease and this Lease shall thereupon be terminated; provided, however, that if Tenant's default is by reason of Tenant's failure to pay Base Rent, Additional Rent or any other amounts payable hereunder, or Tenant's failure to pay Base Rent, Additional Rent or any other amounts payable hereunder, or Tenant's violation of paragraph 17 hereof, then all of Tenant's obligations, including but not limited to, the amount of Base Rent and other obligations reserved in this Lease for the balance of the term hereof, shall immediately be accelerated and due and payable. (2) To re-enter and take possession of the Premises or any part thereof and repossess the same as Landlord's former estate and expel Tenant and those claming through or under Tenant, and remove the effects of both or either, using such force for such purposes as may be reasonably necessary, without being liable for prosecution thereof, without being deemed guilty of any manner of trespass and without prejudice to any remedies for arrears of rent or preceding breach of covenants or conditions. Should Landlord elect to re-enter the Premises as provided in this Paragraph 19(b)(2) or should Landlord take possession pursuant to legal proceedings or pursuant to any notice provided for by law, Landlord may, from time to time, without terminating this Lease, relet the Premises or any part thereof in Landlord's or Tenant's name, but for the amount of Tenant, for such term or terms (which may be greater or less than the period which would otherwise have constituted the balance of the terms of this Lease) and on such conditions and upon such other terms (which may include concessions of free rent and alteration and repair of the Premises) as Landlord, in its discretion, may determine, and Landlord may collect and receive the rents therefor. Landlord shall in no way be responsible or liable for any 15 failure to relet the Premises or any part thereof or for any failure to collect any rent due upon such reletting. No such re-entry or taking possession of the Premises by Landlord shall be construed as an election on Landlord's part to terminate this Lease unless a written notice of such intention be given to Tenant. No notice from Landlord hereunder or under a forcible entry and detainer statute or similar law shall constitute an election by Landlord to terminate this Lease unless such notice specifically so states. Landlord reserves the right following any such re-entry and/or reletting, to exercise its right to terminate this Lease by giving Tenant such written notice, in which event, this Lease will terminate as specified in said notice. (c) In the event that Landlord does not elect to terminate this Lease as permitted in Paragraph 19(b)(1) hereof, but on the contrary, elects to take possession as provided in Paragraph 19(b)(2), Tenant shall pay to Landlord (i) the rent and other sums as herein provided, which would be payable hereunder if such repossession had not occurred, less (ii) the net proceeds, if any, of any reletting, including but without limitation, all repossession costs, brokerage commissions, legal expenses, attorneys' fees, expenses of employees, alteration and repair costs and expenses of preparation for such reletting. If, in connection with any reletting, the new lease term extends beyond the existing term, or the premises covered thereby include other premises not part of the Premises, a fair apportionment of rent received from such reletting and the expenses incurred in connection therewith as provided aforesaid will be made in determining the net proceeds from such reletting. Tenant shall pay such rent and other sums to Landlord monthly on the days on which the rent would have been payable hereunder if possession had not been retaken. (d) In the event this Lease is terminated, Landlord shall be entitled to recover forthwith against Tenant as damages for loss of the bargain and not as a penalty, an aggregate sum which, at the time of such termination of this Lease, represents the excess, if any, of the aggregate of the rent and all other sums payable by Tenant hereunder that would have accrued for the balance of the term over the aggregate rental value of the Premises (such rental value to be computed on the basis of tenant paying not only a rent to Landlord for the use and occupation of the Premises, but also such other charges as are required to be paid by Tenant under the terms of this Lease) for the balance of such term , both discounted to present worth at the rate of eight percent (8%) per annum. Alternatively, at Landlord's option, Tenant shall remain liable to Landlord for damages in an amount equal to the rent and other sums arising under the Lease for the balance of the term had the Lease not been terminated, less the net proceeds, if any, from any subsequent reletting, after deducting all expenses associated therewith and as listed in subparagraph 19(c) above. Landlord shall be entitled to receipt of such amounts from Tenant monthly on the days on which such sums would have otherwise been payable. (e) Suit or suits for the recovery of the amounts and damages set forth above may be brought by Landlord, from time to time, at Landlord's election and nothing herein shall be deemed to require Landlord to await the date whereupon this Lease or the term hereof, would have expired had there been no such default by Tenant or no such termination, as the case may be. (f) After an event of default by Tenant, Landlord may sue for or otherwise collect all rents, issues and profits payable under all subleases on the Premises, including those past due and unpaid. (g) After an event of default by Tenant, Landlord may without terminating this Lease, enter upon the Premises, with force if necessary, without being liable for prosecution of any claim for damages, without being deemed guilty of any manner of trespass and without prejudice to any other remedies, and do whatever Tenant is obligated to do under the terms of this Lease. Tenant agrees to reimburse Landlord on demand for any expenses which Landlord may incur in effecting compliance with the Tenant's obligations under this Lease; further, Tenant agrees that Landlord shall not be liable for any damages resulting to Tenant from effecting compliance with Tenant's obligations under this subparagraph caused by the negligence of Landlord or otherwise. (h) No failure by Landlord to insist upon the strict performance of any agreement, term, covenant or condition hereof or to exercise any right or remedy consequent upon a breach thereof, and no acceptance of full or partial rent during the continuance of any such breach, shall constitute a waiver of any such breach of such agreement, term, covenant or condition. No agreement, term, covenant or condition hereof to be performed or complied with by Tenant, and no breach thereof, shall be waived, altered or modified except by 16 written instrument executed by Landlord. No waiver of any breach shall affect or alter this Lease, but each and every agreement, term, covenant and condition hereof shall continue in full force and effect with respect to any other then existing or subsequent breach thereof. Notwithstanding any unilateral termination of this Lease, this Lease shall continue in force and effect as to any provisions hereof which require observance or performance of Landlord or Tenant subsequent to termination. (i) Nothing contained in this Paragraph shall limit or prejudice the right of Landlord to prove and obtain as liquidated damages in any bankruptcy, insolvency, receivership, reorganization or dissolution proceeding, an amount equal to the maximum allowed by any statute or rule of law governing such proceeding and in affect at the time when such damages are to be proved, whether or not such amount be greater, equal to or less than the amounts recoverable, either as damages or rent, referred to in any of the preceding provisions of this Paragraph. (j) Any rents or other amounts owing to Landlord hereunder which are not paid within five (5) days of the date they are due, shall thereafter bear interest from the due date at a rate equal to the lesser of (i) the maximum non-usurious rate of interest at which Tenant may legally contract in the state in which the Premises are located; or (ii) eighteen percent (18%) per annum ("Interest Rate") until paid. Similarly, any amounts paid by Landlord to cure any default of Tenant or to perform any obligation of Tenant, shall, if not repaid by the Tenant within five (5) days of demand by Landlord, thereafter bear interest from the date paid by Landlord at the Interest Rate until paid. In addition to the foregoing, Tenant shall pay to Landlord whenever any Base Rent, Additional Rent or any other sums due hereunder remain unpaid more than five (5) days thereof, an administrative charge to compensate Landlord for the costs and expenses associated with handling a delinquent account equal to ten percent (10%) of the amount due. Further, in the event of default by Tenant, in addition to all other rights and remedies, Landlord shall be entitled to receive from Tenant all sums, the payment of which may previously have been waived or abated by Landlord, or which may have been paid by Landlord pursuant to any agreement to grant Tenant a rental abatement or other monetary inducement or concession, including but not limited to any tenant finish allowance or moving allowance, together with interest thereon from the date or dates such amounts were paid by Landlord or would have been due from Tenant but for the abatement, at the Interest Rate, until paid; it being understood and agreed that such concession or abatement was made on the condition and basis that Tenant fully perform all obligations and covenants under the Lease for the entire term. (k) Each right and remedy provided for in this Lease shall be cumulative and shall be in addition to every other right or remedy provided for in this Lease now or hereafter existing at law or in equity or by statute or otherwise, including, but not limited to, suits for injunctive or declaratory relief and specific performance. The exercise or commencement of the exercise by Landlord of any one or more of the rights or remedies provided for in this Lease now or hereafter existing at law or in equity or by statute or otherwise shall not preclude the simultaneous or subsequent exercise by Landlord of any or all other rights, or remedies provided for in this Lease, or now or hereafter existing at law or in equity or by statute or otherwise. All costs incurred by Landlord in connection with collecting any amounts and damages owing by Tenant pursuant to the provisions of this Lease or to enforce any provision of this Lease, including by way of example, but not limitation, reasonable attorneys' fees from the date any such matter is turned over to an attorney, shall also be recoverable by Landlord from Tenant. Landlord and Tenant agree that any action or proceeding arising out of this Lease shall be heard by a court sitting without a jury and thus hereby waive all rights to a trial by jury. 20. COMPLETION OF PREMISES: (a) Landlord has agreed to complete the Premises as more fully set forth in a work letter (the "Work Letter") attached hereto and incorporated herein an Exhibit D. Other than as set forth in the Work Letter, Landlord shall have no obligation for the completion of the Premises, and Tenant shall accept the Premises in its "as is" condition on the Commencement Date. Landlord shall not have any obligation for the repair or replacement of any portions of the interior of the Premises, including but not limited to carpeting, draperies, window coverings wallcoverings or painting, which are damaged or wear out during the term hereof, regardless of the cause therefor, except as may otherwise be specifically set forth in this Lease or in Exhibit D-2 attached hereto.
