Landlord shall<br \/>\ndeliver to Tenant, as soon as practicable following the end of any calendar<br \/>\nyear, a calculation of the Operating Expenses for the calendar year just<br \/>\nended and the adjustment in rent resulting from any excess of such Operating<br \/>\nExpenses over the Operating Expenses for the base year of 1999 (the &#8220;Budget<br \/>\nSheet&#8221;). Until receipt of the Budget Sheet, Tenant shall continue to pay its<br \/>\nmonthly Tenant&#8217;s Pro Rata Share of Operating Expenses based upon the amount<br \/>\npaid during the preceding calendar year. To the extent that the Budget Sheet<br \/>\nreflects Tenant&#8217;s Pro Rata Share of Operating Expenses for the new calendar<br \/>\nyear greater than the amount actually paid to the date of receipt of the<br \/>\nBudget Sheet for the new calendar year, Tenant shall pay such amount to<br \/>\nLandlord within thirty (30) days of receipt of the Budget Sheet. Upon receipt<br \/>\nof the Budget Sheet, Tenant shall thereafter pay the amount of its monthly<br \/>\nTenant&#8217;s Pro Rata Share of Operating Expenses as set forth in the Budget<br \/>\nSheet.<\/p>\n<p>                  c. If the Lease term hereunder covers a period of less than<br \/>\na full calendar year during the last calendar year of the term hereof,<br \/>\nTenant&#8217;s Pro Rata Share of Operating Expenses for such partial year shall be<br \/>\nadjusted accordingly to reflect the number of months in such year during<br \/>\nwhich Tenant leased the Premises.<\/p>\n<p>                  d. Tenant shall have the right at its own expense and at a<br \/>\nreasonable time (after written notice to Landlord) within ninety (90) days<br \/>\nafter receipt of the Budget Sheet to audit Landlord&#8217;s books relevant to the<br \/>\nAdditional Rent due under this Paragraph 5. Landlord shall fully cooperate<br \/>\nwith Tenant in connection with such audit. In the event Tenant does not audit<br \/>\nLandlord&#8217;s books and deliver the results thereof to Landlord within said<br \/>\n90-day period, the terms and amounts set forth in the Budget Sheet shall be<br \/>\ndeemed conclusive and final and Tenant shall have no further right to<br \/>\nadjustment unless the failure to complete such audit is caused by Landlord&#8217;s<br \/>\nfailure to provide or make available to Tenant the information necessary to<br \/>\ncomplete such audit, in which case such time period shall be appropriately<br \/>\nexpanded. In the event Tenant&#8217;s examination reveals that an error has been<br \/>\nmade in Landlord&#8217;s determination of Tenant&#8217;s Pro Rata Share of Operating<br \/>\nExpenses and Real Estate Taxes and Landlord agrees with such determination,<br \/>\nthen the amount of such adjustment shall be payable by Landlord or Tenant, to<br \/>\nthe other party as the case may be. In the event Tenant&#8217;s examination reveals<br \/>\nan error has been made in Landlord&#8217;s determination of Tenant&#8217;s Pro Rata Share<br \/>\nof Operating Expenses and Real Estate Taxes, and Landlord disagrees with the<br \/>\nresults thereof, Landlord shall have thirty (30) days to obtain, at its own<br \/>\nexpense, an audit from an accountant of its choice to determine Tenant&#8217;s Pro<br \/>\nRata Share of Operating Expenses and Real Estate Taxes. In the event<br \/>\nLandlord&#8217;s accountant and Tenant&#8217;s accountant are unable to reconcile their<br \/>\naudits, both accountants shall mutually agree upon a third accountant, whose<br \/>\ndetermination of Tenant&#8217;s Pro Rata Share of Operating Expenses and Real<br \/>\nEstate Taxes shall be conclusive. In the event the amount of error by<br \/>\nLandlord is determined to be ten percent (10%) or more, the reasonable costs<br \/>\nof the three audits made pursuant to this <\/p>\n<p>subparagraph shall be paid by Landlord. In the event the amount of error by<br \/>\nLandlord is determined to be less than ten percent (10%), the reasonable<br \/>\ncosts of the three audits made pursuant to this subparagraph shall be paid by<br \/>\nTenant.<\/p>\n<p>                  e. Landlord&#8217;s failure during the Lease term to prepare and<br \/>\ndeliver any statements or bills, or Landlord&#8217;s failure to make a demand under<br \/>\nthis Paragraph or under any other provision of this Lease shall not in any<br \/>\nway be deemed to be a waiver of, or cause Landlord to forfeit or surrender<br \/>\nits rights to collect any items of Additional Rent which may have become due<br \/>\npursuant to this Paragraph during the term of this Lease. Tenant&#8217;s liability<br \/>\nfor all Additional Rent due under this Paragraph 5 shall survive the<br \/>\nexpiration or earlier termination of this Lease.<\/p>\n<p>                  f. Notwithstanding anything in this paragraph 5 to the<br \/>\ncontrary, Tenant shall only be responsible for Additional Rent resulting from<br \/>\nan increase in Operating Expenses over Base Operating Expenses commencing on<br \/>\nthe first day of January, 2001, based on any increase or estimated increase<br \/>\nof Operating Expenses during the calendar year 2000 over those incurred<br \/>\nduring 1999. Thereafter, adjustments in the amount of any Additional Rent<br \/>\nshall occur as of the first day of each calendar year during the remaining<br \/>\nInitial Term and any Extended Term of this Lease.<\/p>\n<p>          6.

To the extent not covered by normal fire and extended<br \/>\ncoverage insurance, Tenant agrees to pay for all damage to the Building<br \/>\nComplex, as well as all damage to persons or property of other tenants or<br \/>\noccupants thereof, caused by the misuse or negligent act or omission of<br \/>\nTenant or any of its agents, contractors, employees, licensees or invitees.<\/p>\n<p>                  (c) Neither party nor their agents or employees shall be<br \/>\nliable to the other party for the loss or damage to any property occurring by<br \/>\ntheft or otherwise, nor for any injury or damage to persons or property<br \/>\nresulting from fire, explosion, falling plaster, steam, gas, electricity,<br \/>\nwater or rain which may leak from any part of the Building Complex or from<br \/>\nthe pipes, appliances or plumbing works therein or from the roof, street or<br \/>\nsubsurface or from any other place or resulting from dampness, or any other<br \/>\ncause whatsoever; provided, however, nothing contained herein shall be<br \/>\nconstrued to relieve either party from liability for any personal injury or<br \/>\nproperty damage resulting from its negligence. Neither Landlord nor its<br \/>\nagents or employees shall be liable for interference with the lights, view or<br \/>\nother incorporeal hereditaments, nor shall Landlord be liable to Tenant or<br \/>\nits officers, employees, guests or invitees for any damages arising from any<br \/>\nlatent defect in the Premises or in the Building or Building Complex unless<br \/>\nresulting from Landlord&#8217;s negligence. Each party shall give prompt notice to<br \/>\nthe other in case of fire or accidents in or about the Premises or the<br \/>\nBuilding or of defects therein or in the fixtures or equipment located<br \/>\ntherein.<\/p>\n<p>                  (d) In case any claim, demand, action or proceeding is made<br \/>\nor brought against Landlord or Tenant, its agents or employees, by reason of<br \/>\nany obligation on the other party&#8217;s part to be performed under the terms of<br \/>\nthis Lease, or arising from any act or negligence of either party, its agents<br \/>\nor employees, or which gives rise to either party&#8217;s obligation to indemnify<br \/>\nthe other, the party shall be responsible for all costs and expenses,<br \/>\nincluding but not limited to reasonable attorneys&#8217; fees incurred in defending<br \/>\nor prosecution of the same, as applicable.<\/p>\n<p>                  (e) Landlord, as a material part of the consideration to be<br \/>\nrendered to Tenant under this Lease, hereby waives all claims of liability<br \/>\nthat Landlord or Landlord&#8217;s legal representatives, successors or assigns may<br \/>\nhave against Tenant and Landlord hereby indemnifies and agrees to hold Tenant<br \/>\nharmless from any and all claims of liability for any injury or damage to any<br \/>\nperson or property whatsoever: (1) occurring in, on or about the Premises or<br \/>\nany part thereof: and (2) occurring in, on or about the Building Complex, to<br \/>\nthe extent such injury or damage is caused by the negligent act or omission<br \/>\nof Landlord, its agents, contractors, or employees. Landlord further agrees<br \/>\nto indemnify and hold Tenant harmless from and against any and all claims<br \/>\narising from any breach or default in the performance of any obligation on<br \/>\nLandlord&#8217;s part to be performed under the terms of this Lease, or arising<br \/>\nfrom any act of negligence of Landlord, or any of its agents, contractors, or<br \/>\nemployees. Such indemnities shall include by way of example, but not<br \/>\nlimitation, all costs, reasonable attorneys&#8217; fees, expenses and liabilities<br \/>\nincurred in or about any such claim, action or proceeding.<\/p>\n<p>          14. INSURANCE:<\/p>\n<p>                  (a) Landlord agrees to carry and maintain the following<br \/>\ninsurance during the term of this Lease and any extension hereof: fire and<br \/>\nextended coverage and general public liability insurance against claims for<br \/>\npersonal injury, including death and property damage in or about the Premises<br \/>\nand the Building or the Building Complex (excluding Tenant&#8217;s Property), such<br \/>\ninsurance to be in amounts sufficient to provide reasonable protection for<br \/>\nthe Building Complex. Such insurance may expressly exclude property paid for<br \/>\nby tenants or paid for by Landlord for which tenants have reimbursed Landlord<br \/>\nlocated in or constituting a part of the Building or the Building Complex.<br \/>\nSuch insurance shall afford coverage for damages resulting from (a) fire, (b)<br \/>\nperils covered by extended coverage insurance, and (c) explosion of steam and<br \/>\npressure boilers and similar apparatus located in the Building or the<br \/>\nBuilding Complex. All such insurance shall be procured from a responsible<br \/>\ninsurance company or companies authorized to do business in Colorado and may<br \/>\nbe obtained by Landlord by endorsement on its blanket insurance policies.<\/p>\n<p>                  (b) Tenant shall procure and maintain at its own cost at<br \/>\nall times during the term of this Lease and any extensions hereof, hazard,<br \/>\nfire and extended coverage on Tenant&#8217;s property and the contents of the<br \/>\nPremises, comprehensive general liability insurance, including coverage for<br \/>\nbodily injury, property damage, personal injury, products, host liquor legal<br \/>\nliability and broad form property damage with the following limits of<br \/>\nliability: One Million Dollars ($1,000,000.00) each occurrence combined<br \/>\nsingle limit for bodily injury, property damage and personal injury; One<br \/>\nMillion Dollars ($1,000,000.00) aggregate for bodily injury and property<br \/>\ndamage and for products liability. All such insurance shall be procured from<br \/>\na responsible insurance company or companies authorized to do business in<br \/>\nColorado, and shall be otherwise satisfactory to Landlord. All such policies<br \/>\nshall name Landlord as an additional insured, and shall provide that the same<br \/>\nmay not be canceled or materially altered except upon thirty (30) days prior<br \/>\nwritten notice to Landlord. All insurance maintained by Tenant shall be<br \/>\nprimary to any insurance provided by Landlord. If Tenant obtains any general<br \/>\nliability insurance policy on a claims-made basis, Tenant shall provide<br \/>\ncontinuous liability coverage for claims arising during the entire term of<br \/>\nthis Lease, regardless of when <\/p>\n<p>such claims are made, either by obtaining an endorsement providing for an<br \/>\nunlimited extended reporting period in the event such policy is canceled or<br \/>\nnot renewed for any reason whatsoever or by obtaining new coverage with a<br \/>\nretroactive date the same as or earlier than the expiration date of the<br \/>\ncanceled or expired policy. Tenant shall provide certificate(s) of such<br \/>\ninsurance to Landlord upon commencement of the Lease term and at least thirty<br \/>\n(30) days prior to any annual renewal date thereof and upon request from time<br \/>\nto time and such certificate(s) shall disclose that such insurance names<br \/>\nLandlord as an additional insured, in addition to the other requirements set<br \/>\nforth herein. The limits of such insurance shall not, under any<br \/>\ncircumstances, limit the liability of Tenant hereunder.<\/p>\n<p>                  (c) Each party agrees to use its best efforts to include in<br \/>\neach of its policies insuring against loss, damage or destruction by fire or<br \/>\nother casualty a waiver of the insurer&#8217;s right of subrogation against the<br \/>\nother party, or if such waiver should be unobtainable or unenforceable (i) an<br \/>\nexpress agreement that such policy shall not be invalidated if the insured<br \/>\nwaives the right of recovery against any party responsible for a casualty<br \/>\ncovered by the policy before the casualty; or (ii) any other form of<br \/>\npermission for the release of the other party. If such waiver, agreement or<br \/>\npermission shall not be, or shall cease to be, obtainable without additional<br \/>\ncharge or at all, the insured party shall so notify the other party promptly<br \/>\nafter learning thereof. In such case, if the other party shall so elect and<br \/>\nshall pay the insurer&#8217;s additional charge therefor, such waiver, agreement or<br \/>\npermission shall be included in the policy, or the other party shall be named<br \/>\nas an additional insured in the policy. Each such policy which shall so name<br \/>\na party hereto as an additional insured shall contain, if obtainable,<br \/>\nagreements by the insurer that the policy will not be canceled without at<br \/>\nleast thirty (30) days prior notice to both insureds and that the act or<br \/>\nomission of one insured will not invalidate the policy as to the other<br \/>\ninsured. Any failure by either party, if named as an additional insured,<br \/>\npromptly to endorse to the order of the other party, without recourse, any<br \/>\ninstrument for the payment of money under or with respect to the policy of<br \/>\nwhich the other party is the owner or original or primary insured, shall be<br \/>\ndeemed a default under this Lease.<\/p>\n<p>                  (d) Each party hereby releases the other party with respect<br \/>\nto any claim (including a claim for negligence) which it might otherwise have<br \/>\nagainst the other party for loss, damage or destruction with respect to its<br \/>\nproperty (including the Building, Building Complex, the Premises and rental<br \/>\nvalue or business interruption) occurring during the term of this Lease to<br \/>\nthe extent to which it is insured under a policy or policies containing a<br \/>\nwaiver of subrogation or permission to release liability or naming the above<br \/>\nparty as an additional insured as provided above.<\/p>\n<p>          15. DAMAGE OR DESTRUCTION TO BUILDING:<\/p>\n<p>                  (a) In the event that the Premises or the Building are<br \/>\ndamaged by fire or other insured casualty and the insurance proceeds have<br \/>\nbeen made available therefor by the holder or holders of any mortgages or<br \/>\ndeeds of trust covering the Building, the damage shall be repaired by and at<br \/>\nthe expense of Landlord to the extent of such insurance proceeds are<br \/>\navailable therefor, provided such repairs and restoration can, in Landlord&#8217;s<br \/>\nreasonable opinion, be made within one hundred fifty (150) days after the<br \/>\noccurrence of such damage without the payment of overtime or <\/p>\n<p>other premiums, and until such repairs and restoration are completed, the<br \/>\nBase Rent shall be abated in proportion to the part of the Premises which is<br \/>\nunusable by Tenant in the conduct of its business, as may be reasonably<br \/>\ndetermined by Landlord, (but there shall be no abatement of Base Rent by<br \/>\nreason of any portion of the Premises being unusable for a period equal to<br \/>\none day or less). Landlord agrees to notify Tenant within forty-five (45)<br \/>\ndays after such casualty if it estimates that it will be unable to repair and<br \/>\nrestore the Premises within said one hundred fifty (150) day period. Such<br \/>\nnotice shall set forth the approximate length of time Landlord estimates will<br \/>\nbe required to complete such repairs and restoration. Notwithstanding<br \/>\nanything to the contrary contained herein, if Landlord cannot or estimates it<br \/>\ncannot make such repairs and restoration within said one hundred fifty (150)<br \/>\nday period or fails to do complete such repairs and restoration within said<br \/>\n150-day period, then Tenant may, by written notice to Landlord, cancel this<br \/>\nLease, provided such notice is given to Landlord within fifteen (15) days<br \/>\nafter Landlord notifies Tenant of the estimated time for completion of such<br \/>\nrepairs and restoration, or within 15 days following the expiration of said<br \/>\n150-day period, as the case may be. Notwithstanding the preceding sentence,<br \/>\nTenant may not cancel this Lease as hereinabove stated if the damage to the<br \/>\nPremises or the Building is in whole or in part the result of the act,<br \/>\nomission, fault or negligence of Tenant, its agents, contractors, employees,<br \/>\nlicensees or invitees. Except as provided in this Paragraph 15, there shall<br \/>\nbe no abatement of rent and no liability of Landlord by reason of any injury<br \/>\nto or interference with Tenant&#8217;s business or property arising from the making<br \/>\nof any such repairs, alterations or improvements in or to the Building,<br \/>\nPremises or fixtures, appurtenances and equipment. Tenant understands that<br \/>\nLandlord will not carry insurance of any kind on Tenant&#8217;s Property, including<br \/>\nfurniture and furnishings, or on any fixtures or equipment removable by<br \/>\nTenant under the provisions of this Lease, or any improvement installed in<br \/>\nthe Premises by or on behalf of Tenant, and that Landlord shall not be<br \/>\nobligated to repair any damage thereto or replace the same.<\/p>\n<p>                  (b) In case the Building throughout shall be so injured or<br \/>\ndamaged, whether by fire or otherwise (though the Premises may not be<br \/>\naffected, or if affected, can be repaired within said 150 days) that<br \/>\nLandlord, within sixty (60) days after the happening of such injury, shall<br \/>\ndecide not to reconstruct or rebuild the Building, then notwithstanding<br \/>\nanything contained herein to the contrary, upon notice in writing to that<br \/>\neffect given by Landlord to Tenant within said sixty (60) days, Tenant shall<br \/>\npay the rent, properly apportioned up to date of such casualty, this Lease<br \/>\nshall terminate from the date of delivery of said written notice, and both<br \/>\nparties hereto shall be released and discharged from all further obligations<br \/>\nhereunder (except those obligations which expressly survive termination of<br \/>\nthe Lease term). A total destruction of the Building shall automatically<br \/>\nterminate this Lease.<\/p>\n<p>          16. CONDEMNATION:<\/p>\n<p>                  (a) If the whole of the Premises or so much thereof as to<br \/>\nrender the balance unusable by Tenant for the proper conduct of its business (in<br \/>\nthe reasonable opinion of Tenant) shall be taken under power of eminent domain<br \/>\nor transferred under threat thereof, then this Lease, at the option of either<br \/>\nLandlord or Tenant exercised by either party giving notice to the other of such<br \/>\nelection within thirty (30) days after such conveyance or taking possession,<br \/>\nwhichever is earlier, shall forthwith cease and terminate and the rent shall be<br \/>\nduly apportioned as of the date of such taking or <\/p>\n<p>conveyance. No award for any partial or entire taking of the real property<br \/>\nand its fixtures which constitute part of the real property under the terms<br \/>\nof this Lease shall be apportioned and Tenant hereby assigns to Landlord any<br \/>\naward which may be made in such taking or condemnation, together with any and<br \/>\nall rights of Tenant now or hereafter arising in or to the same or any part<br \/>\nthereof. Notwithstanding the foregoing, Tenant shall be entitled to seek,<br \/>\ndirectly from the condemning authority, an award for its removable trade<br \/>\nfixtures, equipment and personal property and relocation expenses, if any, to<br \/>\nthe extent Landlord&#8217;s award is not diminished. In the event of a partial<br \/>\ntaking which does not result in a termination of this Lease, Base Rent and<br \/>\nAdditional Rent and other obligations hereunder shall be reduced in<br \/>\nproportion to the reduction in the size of the Premises so taken and this<br \/>\nLease shall be modified accordingly. Promptly after obtaining knowledge<br \/>\nthereof, Landlord or Tenant, as the case may be, shall notify the other of<br \/>\nany pending or threatened condemnation or taking affecting the Premises or<br \/>\nthe Building.<\/p>\n<p>                  (b) If all or any portion of the Premises shall be<br \/>\ncondemned or taken for governmental occupancy for a limited period, this<br \/>\nLease shall not terminate and Landlord shall be entitled to receive the<br \/>\nentire amount of any such award or payment thereof as damages, rent or<br \/>\notherwise. Tenant hereby assigns to Landlord any award which may be made in<br \/>\nsuch temporary taking, together with any and all rights of Tenant now or<br \/>\nhereafter arising in or to the same or any part thereof. Tenant shall be<br \/>\nentitled to receive an abatement of Base Rent and Additional Rent and other<br \/>\nrental obligations hereunder during the period of time possession is taken<br \/>\nand in proportion to the reduction in the size of the Premises so taken.<\/p>\n<p>          17. ASSIGNMENT AND SUBLETTING:<\/p>\n<p>                  (a) Except as expressly provided in this Paragraph 17,<br \/>\nTenant shall not, voluntarity, involuntarily or otherwise, sublet all or any<br \/>\nportion of the Premises or assign all or any portion of Tenant&#8217;s rights under<br \/>\nthis Lease or permit any part of the Premises to be used or occupied by any<br \/>\npersons other than Tenant and its employees, nor shall Tenant permit any part<br \/>\nof the Premises to be used or occupied by any licensee or concessionaire or<br \/>\npermit any persons other than Tenant, its employees and invitees, to be upon<br \/>\nthe Premises. Tenant shall not voluntarily, by operation of law, or<br \/>\notherwise, assign, transfer or encumber this Lease or any interest herein nor<br \/>\nsublet or part with possession of all or any part of the Premises (any and<br \/>\nall of which shall hereinafter be referred to as &#8220;Transfer&#8221;) without<br \/>\nLandlord&#8217;s prior written consent, which consent shall not be unreasonably<br \/>\nwithheld or delayed.<\/p>\n<p>         Landlord shall be under no obligation to consent to any sublease,<br \/>\ntransfer or assignment if: (i) Tenant is then in default of any term or<br \/>\ncondition of this Lease or (ii) any event has occurred which, with the giving<br \/>\nof notice, the passage of time, or both would constitute a default hereunder.<\/p>\n<p>         No such sublease or assignment shall relieve Tenant of its<br \/>\nobligations hereunder, except as expressly provided for in this Paragraph 17.<\/p>\n<p>         Any Transfer without the prior written consent of Landlord shall<br \/>\nconstitute a <\/p>\n<p>default hereunder and shall be void AB INITIO and shall confer no rights upon<br \/>\nany third party, notwithstanding Landlord&#8217;s acceptance of rent payments from<br \/>\nany purported transferee.<\/p>\n<p>         Tenant may, without Landlord&#8217;s consent being first required, assign<br \/>\nthis Lease or sublet all or any portion of the Premises to a wholly owned<br \/>\nsubsidiary of Tenant, to a corporate parent of Tenant owning a majority of<br \/>\nthe issued and outstanding common stock of Tenant, or to a corporation the<br \/>\nmajority of whose stock is held by a corporate parent of Tenant. No such<br \/>\nassignment or subletting shall relieve Tenant of its obligations hereunder.<\/p>\n<p>          Landlord&#8217;s consent to any requested assignment of this Lease or<br \/>\nsubletting of all or any part of the Premises (other than those expressly<br \/>\npermitted in the preceding paragraph) shall be subject to the following<br \/>\nconditions:<\/p>\n<p>                           (1) such consent and resulting subletting or<br \/>\nassignment shall not relieve Tenant of its primary obligations hereunder,<br \/>\nincluding the obligation for payment of all rents due hereunder;<\/p>\n<p>                           (2) Should Tenant default of the payment of Rent<br \/>\nor Additional Rent hereunder, Landlord, at its option and from time to time,<br \/>\nmay collect the rent from the subtenant or assignee, and apply the net amount<br \/>\ncollected to the rent herein reserved, but no such collection shall be deemed<br \/>\nan acceptance by Landlord of the subtenant or assignee as the tenant hereof,<br \/>\nor a release of Tenant from further performance of covenants on the part of<br \/>\nTenant herein contained;<\/p>\n<p>                           (3) any such subtenant or assignee shall be a<br \/>\ncompany or other entity of good repute, engaged in a business or profession<br \/>\ncompatible with and in keeping with the then standards of the Building and<br \/>\nfinancially capable of performing its obligations with respect to the<br \/>\nPremises; and<\/p>\n<p>                           (4) such subtenant or assignee shall assume and<br \/>\nagree to perform all of Tenant&#8217;s obligations under this Lease insofar as they<br \/>\npertain to the space so sublet or assigned.<\/p>\n<p>                           (5) Tenant is not in default of any term or<br \/>\ncondition of this Lease at the time it requests Landlord&#8217;s consent.<\/p>\n<p>                  (b) In the event of any Transfer of this Lease or all or<br \/>\nany part of the Premises by Tenant without Landlord&#8217;s consent (other than<br \/>\nthose expressly permitted above), Landlord in addition to any rights<br \/>\ncontained herein, shall have the following options at its reasonable<br \/>\ndiscretion:<\/p>\n<p>                           (1) To collect and receive the excess of rent due<br \/>\nto Tenant from such sublessee or assignee over the Base Rent due hereunder;<\/p>\n<p>                           (2) To give Tenant written notice of Landlord&#8217;s<br \/>\nintention to terminate this Lease on the date such notice is given or on any<br \/>\nlater date specified therein, whereupon, on the date specified in such<br \/>\nnotice, Tenant&#8217;s right to possession <\/p>\n<p>of the Premises shall cease and this Lease shall thereupon be terminated,<br \/>\nexcept as to any uncompleted obligations of Tenant; or<\/p>\n<p>                           (3) To re-enter and take possession of the<br \/>\nPremises or the part thereof subject to such Transfer, and to enforce all<br \/>\nrights of Tenant, and receive and collect all rents and other payments due to<br \/>\nTenant, in accordance with such sublet or assignment of the Premises, or any<br \/>\npart thereof, as if Landlord was the sublettor or assignor, and to do<br \/>\nwhatever Tenant is permitted to do pursuant to the terms of such sublease or<br \/>\nassignment.<\/p>\n<p>                  (c) The sale of all or a majority of the stock of Tenant,<br \/>\nor the sale of all or substantially all of the assets of Tenant shall<br \/>\nconstitute a Transfer for purposes of this Lease, unless such sale is to a<br \/>\n&#8220;Permitted Transferee.&#8221; A Permitted Transferee is any entity that (i) has a<br \/>\ntangible net worth of not less that $15,000,000, (ii) has cash or cash<br \/>\nequivalents of not less than $5,000,000, (iii) whose total liabilities to<br \/>\ntangible net worth do not exceed 1\/5 to 1, and (iv) agrees in writing to<br \/>\nhonor each of the provisions of this Lease. Without limiting the generality<br \/>\nof the foregoing and notwithstanding any other provisions of this Lease, no<br \/>\nconsent shall be required for, and no default shall occur as a result of: (i)<br \/>\nthe transfer of all or more than a majority of the capital stock of Tenant to<br \/>\nany Permitted Transferee, or the transfer of all or substantially all of the<br \/>\nassets of Tenant to any Permitted Transferee, or (ii) the assignment of this<br \/>\nLease to any Permitted Transferee who becomes the holder of all or more than<br \/>\na majority of the capital stock of Tenant or all or substantially all of the<br \/>\nassets of Tenant.<\/p>\n<p>                  (d) At the time of making a request for Landlord&#8217;s consent<br \/>\nto a Transfer and not less than thirty (30) days prior to the proposed<br \/>\neffective date thereof, Tenant shall provide to Landlord such information as<br \/>\nLandlord, its accountants and attorneys, shall reasonably require with<br \/>\nrespect to such proposed Transfer, including but not limited to name and<br \/>\naddress of the proposed transferee, description of business operations,<br \/>\nfinancial information and certificate of corporate authority and good<br \/>\nstanding or partnership certificate, as applicable.<\/p>\n<p>                  (e) Consent of Landlord to a Transfer shall not relieve<br \/>\nTenant from seeking consent to any subsequent Transfers.<\/p>\n<p>                  (f) Subletting or assignments of a sublease by subtenants<br \/>\nshall not be permitted under any circumstances. Further, no option to renew<br \/>\nor extend the term of this Lease or to lease additional space, if any, shall<br \/>\nbe exercisable by any subtenant. If Tenant obtains Landlord&#8217;s consent to an<br \/>\nassigment of this Lease, the assignee shall be entitled to sublease and<br \/>\nfurther assign this Lease and to exercise the Tenant&#8217;s rights to renew or<br \/>\nextend the term of this Lease or to lease additional space, all as provided<br \/>\nherein and subject to the terms and conditions as herein prescribed.<\/p>\n<p>                  (g) All subleases or assignments shall be in writing and a<br \/>\ncopy thereof provided to Landlord within ten (10) days of its effective date.<br \/>\nAll subleases shall further contain an express provision that in the event of<br \/>\nany default by Tenant in the payment of rent or additional rent due hereunder<br \/>\nand upon notice thereof to the Tenant and subtenant from Landlord, all<br \/>\nrentals payable by the subtenant shall be paid directly to Landlord, for the<br \/>\nTenant&#8217;s account, until subsequent notice from Landlord that such <\/p>\n<p>default has been cured. Notwithstanding the foregoing, receipt by Landlord of<br \/>\nrent directly from the subtenant shall not be considered a waiver of the<br \/>\ndefault on the part of Tenant, nor an acceptance of such subtenant.<\/p>\n<p>         18.

Landlord&#8217;s or Tenant&#8217;s failure or refusal to deliver such statement<br \/>\nwithin such time shall be a default under this Lease. Notwithstanding the<br \/>\nforegoing, in the event that Tenant does not execute the statement required<br \/>\nby this Paragraph within 10 business days of written request, then, so long<br \/>\nas such failure or delay is not due to Tenant&#8217;s refusal to include additional<br \/>\nmatters that are not reasonable, or the requesting party&#8217;s refusal to permit<br \/>\ndisclosure by Tenant of exceptions to such statement, Tenant hereby grants to<br \/>\nLandlord a power of attorney coupled with an interest to act as Tenant&#8217;s<br \/>\nattorney in fact for the purpose of executing such statement or statements<br \/>\nrequired by this Paragraph. Such power of attorney shall not grant Landlord<br \/>\nthe right to execute a statement that includes any matters that are not<br \/>\nexpressly covered in this Paragraph or that does not include any exceptions<br \/>\nthat may have been raised by Tenant or of which Landlord is aware.<\/p>\n<p>         19.

PROVIDED, HOWEVER, all of Tenant&#8217;s obligations,<br \/>\nincluding, but not limited to, repayment of the Tenant Build-Out Allowance<br \/>\npaid by Landlord on behalf of Tenant pursuant to the terms of the Work Letter<br \/>\nAgreement executed by Landlord and Tenant in the form attached hereto as<br \/>\nEXHIBIT D, with interest at the rate of 18% per annum, compounded annually, <\/p>\n<p>computed from the date(s) of payment by Landlord (such sum with interest<br \/>\nhereinafter referred to as the &#8220;Allowance Recovery&#8221;) and the amount of Base<br \/>\nRent and other obligations reserved in this Lease for the balance of the term<br \/>\nhereof, shall immediately be accelerated and due and payable in the manner<br \/>\nand to the extent provided in paragraph 19(d), below.<\/p>\n<p>                           (2) To re-enter and take possession of the<br \/>\nPremises or any part thereof and repossess the same as Landlord&#8217;s former<br \/>\nestate and expel Tenant and those claiming through or under Tenant, and<br \/>\nremove the effects of both or either, using such force for such purposes as<br \/>\nmay be reasonably necessary, without being liable for prosecution thereof,<br \/>\nwithout being deemed guilty of any manner of trespass and without prejudice<br \/>\nto any remedies for arrears of rent or preceding breach of covenants or<br \/>\nconditions; PROVIDED, HOWEVER, any such action shall be in compliance with<br \/>\nthe provisions of Article 40 of Title 13, Colorado Revised Statutes. Should<br \/>\nLandlord elect to re-enter the Premises as provided in this Paragraph<br \/>\n19(b)(2) or should Landlord take possession pursuant to legal proceedings or<br \/>\npursuant to any notice provided for by law, Landlord may, from time to time,<br \/>\nwithout terminating this Lease, relet the Premises or any part thereof, in<br \/>\nLandlord&#8217;s or Tenant&#8217;s name, but for the account of Tenant, for such term or<br \/>\nterms (which may be greater or less than the period which would otherwise<br \/>\nhave constituted the balance of the term of this Lease) and on such<br \/>\nconditions and upon such other terms (which may include concessions of free<br \/>\nrent and alteration and repair of the Premises) as Landlord, in its<br \/>\ndiscretion, may determine, and Landlord may collect and receive the rents<br \/>\ntherefor. Landlord shall use commercially reasonable efforts to relet the<br \/>\nPremises or any part thereof. No such re-entry or taking possession of the<br \/>\nPremises by Landlord shall be construed as an election on Landlord&#8217;s part to<br \/>\nterminate this Lease unless a written notice of such intention be given to<br \/>\nTenant. No notice from Landlord hereunder or under a forcible entry and<br \/>\ndetainer statute or similar law shall constitute an election by Landlord to<br \/>\nterminate this Lease unless such notice specifically so states. Landlord<br \/>\nreserves the right following any such re-entry and\/or reletting, to exercise<br \/>\nits right to terminate this Lease by giving Tenant such written notice, in<br \/>\nwhich event, this Lease will terminate as specified in said notice.<\/p>\n<p>                  (c) In the event that Landlord does not elect to terminate<br \/>\nthis Lease as permitted in Paragraph 19(b)(1) hereof, but on the contrary,<br \/>\nelects to take possession as provided in Paragraph 19(b)(2), Tenant shall pay<br \/>\nto Landlord (i) the rent and other sums as herein provided, which would be<br \/>\npayable hereunder if such repossession had not occurred, plus (ii) the amount<br \/>\nof the Allowance Recovery, less (iii) the net proceeds, if any, of any<br \/>\nreletting of the Premises after deducting all Landlord&#8217;s expenses in<br \/>\nconnection with such reletting, including but without limitation, all<br \/>\nrepossession costs, brokerage commissions, legal expenses, reasonable<br \/>\nattorneys&#8217; fees, expenses of employees, alteration and repair costs and<br \/>\nexpenses of preparation for such reletting. If, in connection with any<br \/>\nreletting, the new lease term extends beyond the existing term, or the<br \/>\npremises covered thereby include other premises not part of the Premises, a<br \/>\nfair apportionment of the rent received from such reletting and the expenses<br \/>\nincurred in connection therewith as provided aforesaid will be made in<br \/>\ndetermining the net proceeds from such reletting. Tenant shall pay such rent<br \/>\nand other sums to Landlord monthly on the days on which the rent would have<br \/>\nbeen payable hereunder if possession had not been retaken.<\/p>\n<p>                  (d) In the event this Lease is terminated pursuant to<br \/>\nParagraph 19(b)(1) hereof, Landlord shall be entitled to recover forthwith<br \/>\nagainst Tenant as damages for loss of the bargain and not as a penalty, an<br \/>\naggregate sum which, at the time of such termination of this Lease,<br \/>\nrepresents the excess, if any, of the aggregate of the rent and all other<br \/>\nsums payable by Tenant hereunder that would have accrued for the balance of<br \/>\nthe term over the aggregate rental value of the Premises (such rental value<br \/>\nto be computed on the basis of a tenant paying not only a rent to Landlord<br \/>\nfor the use and occupation of the Premises, but also such other charges as<br \/>\nare required to be paid by Tenant under the terms of this Lease) for the<br \/>\nbalance of such term, both discounted to present worth at the rate of eight<br \/>\npercent (8%) per annum, plus the amount of the Allowance Recovery.<br \/>\nAlternatively, at Landlord&#8217;s option, Tenant shall pay to Landlord upon demand<br \/>\nthe amount of the Allowance Recovery, and Tenant shall remain liable to<br \/>\nLandlord for damages in an amount equal to the rent and other sums arising<br \/>\nunder the Lease for the balance of the term had the Lease not been<br \/>\nterminated, less the net proceeds, if any, from any subsequent reletting,<br \/>\nafter deducting all expenses associated therewith and as enumerated above.<br \/>\nLandlord shall be entitled to receipt of such amounts from Tenant monthly on<br \/>\nthe days on which such sums would have otherwise been payable.<\/p>\n<p>                  (e) Suit or suits for the recovery of the amounts and<br \/>\ndamages set forth above may be brought by Landlord, from time to time, at<br \/>\nLandlord&#8217;s election and nothing herein shall be deemed to require Landlord to<br \/>\nawait the date whereon this Lease or the term hereof would have expired had<br \/>\nthere been no such default by Tenant or no such termination, as the case may<br \/>\nbe.<\/p>\n<p>                  (f) After an event of default by Tenant, Landlord may sue<br \/>\nfor or otherwise collect all rents, issues and profits payable under all<br \/>\nsubleases on the Premises including those past due and unpaid.<\/p>\n<p>                  (g) After an event of default by Tenant, Landlord may,<br \/>\nwithout terminating this Lease, enter upon the Premises, with force if<br \/>\nnecessary without being liable for prosecution of any claim for damages,<br \/>\nwithout being deemed guilty of any manner of trespass and without prejudice<br \/>\nto any other remedies, and do whatever Tenant is obligated to do under the<br \/>\nterms of this Lease. Tenant agrees to reimburse Landlord on demand for any<br \/>\nexpenses which Landlord may incur in effecting compliance with the Tenant&#8217;s<br \/>\nobligations under this Lease; further, Tenant agrees that Landlord shall not<br \/>\nbe liable for any damages resulting to Tenant from effecting compliance with<br \/>\nTenant&#8217;s obligations under this subparagraph caused by the negligence of<br \/>\nLandlord.<\/p>\n<p>                  (h) No failure by Landlord to insist upon the strict<br \/>\nperformance of any agreement, term, covenant or condition hereof or to<br \/>\nexercise any right or remedy consequent upon a breach thereof, and no<br \/>\nacceptance of full or partial rent during the continuance of any such breach,<br \/>\nshall constitute a waiver of any such breach of such agreement, term,<br \/>\ncovenant or condition. No agreement, term, covenant or condition hereof to be<br \/>\nperformed or complied with by Tenant, and no breach thereof, shall be waived,<br \/>\naltered or modified except by written instrument executed by Landlord. No<br \/>\nwaiver of any breach shall affect or alter this Lease, but each and every<br \/>\nagreement, term, covenant and condition hereof shall continue in full force<br \/>\nand effect with respect <\/p>\n<p>to any other then existing or subsequent breach thereof. Notwithstanding any<br \/>\nunilateral termination of this Lease, this Lease shall continue in force and<br \/>\neffect as to any provisions hereof which require observance or performance of<br \/>\nLandlord or Tenant subsequent to termination.<\/p>\n<p>                  (i) Nothing contained in this Paragraph shall limit or<br \/>\nprejudice the right of Landlord to prove and obtain as liquidated damages in<br \/>\nany bankruptcy, insolvency, receivership, reorganization or dissolution<br \/>\nproceeding, an amount equal to the maximum allowed by any statute or rule of<br \/>\nlaw governing such proceeding and in effect at the time when such damages are<br \/>\nto be proved, whether or not such amount be greater, equal to or less than<br \/>\nthe amounts recoverable, either as damages or rent, referred to in any of the<br \/>\npreceding provisions of this Paragraph.<\/p>\n<p>                  (j) Any rents or other amounts owing to Landlord hereunder<br \/>\nwhich are not paid within ten (10) days of the date they are due, shall<br \/>\nthereafter bear interest from the due date at the rate of eighteen percent<br \/>\n(18%) per annum (&#8220;Interest Rate&#8221;) until paid. Similarly, any amounts paid by<br \/>\nLandlord to cure any default of Tenant or to perform any obligation of<br \/>\nTenant, shall, if not repaid by the Tenant within five (5) days of demand by<br \/>\nLandlord, thereafter bear interest from the date paid by Landlord at the<br \/>\nInterest Rate until paid. In addition to the foregoing, Tenant shall pay to<br \/>\nLandlord whenever any Base Rent, Additional Rent or any other sums due<br \/>\nhereunder remain unpaid more than ten (10) days after the due date thereof, a<br \/>\nlate charge equal to five percent (5%) of the amount due.<\/p>\n<p>                  (k) Each right and remedy provided for in this Lease shall<br \/>\nbe cumulative and shall be in addition to every other right or remedy<br \/>\nprovided for in this Lease now or hereafter existing at law or in equity or<br \/>\nof statute or otherwise, including, but not limited to, suits for injunctive<br \/>\nor declaratory relief and specific performance. The exercise or commencement<br \/>\nof the exercise by either party of any one or more of the rights or remedies<br \/>\nprovided for in this Lease now or hereafter existing at law or in equity or<br \/>\nby statute or otherwise shall not preclude the simultaneous or subsequent<br \/>\nexercise by said party of any or all other rights or remedies provided for in<br \/>\nthis Lease, or now or hereafter existing at law or in equity or by statute or<br \/>\notherwise. All costs incurred by either party in connection with collecting<br \/>\nany amounts and damages owing by the other party pursuant to the provisions<br \/>\nof this Lease or to enforce any provision of this Lease, including, by way of<br \/>\nexample, but not limitation, reasonable attorneys&#8217; fees from the date any<br \/>\nsuch matter is turned over to an attorney, shall also be recoverable by the<br \/>\nprevailing party. Landlord and Tenant agree that any action or proceeding<br \/>\narising out of this Lease shall be heard by a court sitting without a jury<br \/>\nand thus hereby waive all rights to a trial by jury.<\/p>\n<p>         20.

Notwithstanding the foregoing, in the event that Tenant fails to<br \/>\nexecute such documents as may be required to confirm the subordination set<br \/>\nforth in this Paragraph, then, so long as such failure or delay is not due to<br \/>\nTenant&#8217;s refusal to execute docuuments that contain unreasonable terms or<br \/>\nconditions beyond what is required by this Paragraph, or the requesting<br \/>\nparty&#8217;s refusal to accept reasonable changes to such documents that will not<br \/>\ndiminish the subordination granted by this Paragraph, Tenant hereby grants to<br \/>\nLandlord a power of attorney coupled with an interest to act as Tenant&#8217;s<br \/>\nattorney in fact for the purposes of executing such documents. Such power of<br \/>\nattorney shall not grant Landlord the right to execute documets that grant<br \/>\nrights or impose obligations beyond the subordination covered in this<br \/>\nParagraph. The deeds of trust or mortgages to which this Lease is, at the<br \/>\ntime referred to, subject and subordinate are hereinafter sometimes called<br \/>\n&#8220;superior deeds of trust&#8221; or &#8220;superior mortgages&#8221;. The beneficiary of a<br \/>\nsuperior deed of trust or superior mortgage or their successors in interest<br \/>\nor assigns are hereinafter sometimes collectively referred to as a &#8220;superior<br \/>\nparty&#8221;. The subordination provided by this Section 26 shall be subject to the<br \/>\nprovision that, and any subordination entered into by Tenant after the date<br \/>\nof this Lease must contain a non-disturbance agreement in the form then being<br \/>\nused by such superior party for such purposes, providing that, in any case,<br \/>\nTenant, notwithstanding such subordination or a default by Landlord, shall be<br \/>\nentitled to remain in possession of the Premises in accordance with the terms<br \/>\nof this Lease for so long as Tenant shall not be in default of any term,<br \/>\ncondition or covenant of this Lease. Further, Tenant shall attorn to such<br \/>\nsuperior party.<\/p>\n<p>                  (b) Tenant shall take no steps to terminate this Lease,<br \/>\nwithout giving written notice to such superior party, and a reasonable<br \/>\nopportunity to cure (without such superior party being obligated to cure),<br \/>\nany default on the part of Landlord under this Lease, provided Tenant shall<br \/>\nbe obliged to notify only such superior parties of which Tenant has actual<br \/>\nknowledge by virtue of a prior written communication from Landlord or such<br \/>\nsuperior party.<\/p>\n<p>                  (c) If, in connection with the procurement, continuation or<br \/>\nrenewal of any financing for which the Building or the Building Complex<br \/>\nrepresents collateral in whole or in part, a lender shall request reasonable<br \/>\nmodifications of this Lease as a condition of such financing, Tenant will not<br \/>\nunreasonably withhold its consent thereto provided that such modifications do<br \/>\nnot increase the obligations of Tenant under this Lease or adversely affect<br \/>\nany rights of Tenant or decrease the obligations of Landlord under this Lease.<\/p>\n<p>         27. PAYMENTS AFTER TERMINATION: No payments of money by Tenant to<br \/>\nLandlord after the termination of this Lease, in any manner, or after giving<br \/>\nof any notice (other than a demand for payment of money) by Landlord to<br \/>\nTenant, shall reinstate, continue or extend the term of this Lease or affect<br \/>\nany notice given to Tenant prior to the payment of such money, it being<br \/>\nagreed that after the service of notice of the commencement of a suit or<br \/>\nother final judgment granting Landlord possession of the Premises, Landlord<br \/>\nmay receive and collect any sums of rent due, or any other sums of money due<br \/>\nunder the terms of this Lease or otherwise exercise its rights and remedies<br \/>\nhereunder. The payment of such sums of money, whether as rent or otherwise,<br \/>\nshall not waive said notice or in any manner affect any pending suit or<br \/>\njudgment theretofore obtained.<\/p>\n<p>         28.

If Tenant breaches the obligations stated in the<br \/>\npreceding sentence, or if the presence of Hazardous Material on the Premises<br \/>\ncaused or permitted by Tenant results in contamination of the Premises or<br \/>\nBuilding Complex, or any part thereof, or if contamination of the Premises or<br \/>\nBuilding Complex by Hazardous Material otherwise occurs for which Tenant is<br \/>\nlegally liable to Landlord for damage resulting therefrom, then Tenant shall<br \/>\nindemnify, defend and hold Landlord, its agents, employees, legal<br \/>\nrepresentatives, successors and assigns, harmless from any and all claims,<br \/>\njudgments, damages, penalties, fines, costs, liabilities, or losses<br \/>\n(including, without limitation, diminution in value of the Premises and<br \/>\nbuilding Complex, damages for the loss or restriction on use of any rentable<br \/>\nor usable space or of any amenity of the Premises or Building Complex,<br \/>\ndamages arising from any adverse impact on marketing of space in the<br \/>\nBuilding, and sums paid in settlement of claims, reasonable attorneys&#8217; fees,<br \/>\nconsultant fees and expert fees) which arise during or after the Lease term<br \/>\nas a result of such contamination. This indemnification of Landlord by Tenant<br \/>\nincludes, without limitation, such costs incurred in connection with any<br \/>\ninvestigation of site conditions or any cleanup, remedial, removal or<br \/>\nrestoration work required by any federal, state, or local governmental agency<br \/>\nor political subdivision because of Hazardous Material caused or permitted by<br \/>\nTenant to be present in or about the Building Complex or the soil or ground<br \/>\nwater on or under the Building Complex. Without limiting the foregoing, if<br \/>\nthe presence of any Hazardous Material on or about the Building Complex<br \/>\ncaused or permitted by Tenant results in any contamination of any portion<br \/>\nthereof, Tenant shall promptly take all actions at its sole expense as are<br \/>\nnecessary to return the Building Complex to the condition existing prior to<br \/>\nthe introduction of any such Hazardous Material, subject to obtaining<br \/>\nLandlord&#8217;s prior written consent to the actions to be taken by Tenant.<br \/>\nLandlord may properly require its consent to the selection of the contractors<br \/>\nand other experts involved in the inspection, testing and removal or<br \/>\nabatement activities, the scope of activities to be performed, the manner and<br \/>\nmethod for performance of such activities, and such other matters as may be<br \/>\nrequired or requested by Landlord for the safety of and continued use of the<br \/>\nBuilding Complex and all occupants thereof. The obligations and liabilities<br \/>\nof Tenant herein shall survive expiration or termination of this Lease.<\/p>\n<p>                  (b) &#8220;Hazardous Material,&#8221; as used in this Lease, shall be<br \/>\nconstrued in its broadest sense and shall include asbestos, other asbestotic<br \/>\nmaterial (which is currently or may be designated in the future as a<br \/>\nHazardous Material), any petroleum base products, pesticides, paints and<br \/>\nsolvents, polychlorinated biphenyl, lead, cyanide, DDT, acids, ammonium<br \/>\ncompounds and other chemical products (excluding commercially used cleaning<br \/>\nmaterials in ordinary quantities) and any substance or material if defined or<br \/>\ndesignated as hazardous or toxic substance, or other similar term, by any<br \/>\nfederal, state or local law, statute, regulation, or ordinance affecting the<br \/>\nBuilding Complex or Premises presently in effect or that may be promulgated<br \/>\nin the future, as such statutes, regulations and ordinances may be amended<br \/>\nfrom time to time.<\/p>\n<p>                  (c) In the event Tenant causes or permits Hazardous<br \/>\nMaterial to be brought upon, kept, or used in or about the Premise, with or<br \/>\nwithout Landlord&#8217;s consent, and Landlord has reason to believe that such<br \/>\nHazardous Materials are contaminating or may contaminate the Building Complex<br \/>\nor soils or water, or pose a threat to the health of other occupants of the<br \/>\nBuilding Complex, Landlord shall be entitled to have an environmental audit<br \/>\nperformed , the reasonable costs and expense of which shall be paid by<br \/>\nTenant. Except in the case of an obvious and immediate threat and danger,<br \/>\nLandlord&#8217;s &#8220;reason to believe,&#8221; as used above, shall be established by a<br \/>\nstudy conducted, at Landlord&#8217;s expense, by a reputable environmental<br \/>\nconsultant into the materials present, Tenant&#8217;s handling of the same, safety<br \/>\nmeasures in place, and compliance with all local state and federal laws,<br \/>\nrules and regulations regulating such materials and the use, transportation<br \/>\nand disposal of the same.<\/p>\n<p>         39.  OPTION TO EXTEND:<\/p>\n<p>         Tenant shall have the right, if not in default at the time of<br \/>\nexercise of the option, to extend the original term of this Lease for two<br \/>\nrenewal terms of five (5) years each (each hereinafter called a &#8220;Renewal<br \/>\nTerm&#8221;). Each Renewal Term shall begin upon the expiration of the original<br \/>\nLease Term, or upon expiration of the first Renewal Term, as the case may be.<br \/>\nAll of the terms, provisions, and covenants of this Lease shall apply to each<br \/>\nRenewal Term; PROVIDED, HOWEVER, the Base Rent payable during each Renewal<br \/>\nTerm shall be at ninety-five percent (95%) of the fair market rental value<br \/>\ndetermined as hereinafter set forth, at the commencement of each Renewal<br \/>\nTerm. Tenant shall exercise such option by delivering to Landlord written<br \/>\nnotice of its election to renew no later than six (6) months prior to the<br \/>\nexpiration of the original Lease Term or the first Renewal Term. For the<br \/>\npurposes of this Lease, the term &#8220;Lease Term&#8221; shall mean the original Lease<br \/>\nTerm plus any applicable Renewal Term.<\/p>\n<p>         Within fourteen (14) days after the Landlord&#8217;s receipt of the<br \/>\nTenant&#8217;s Notice of its election to renew, Landlord and Tenant shall meet and<br \/>\nshall seek to establish the fair market rental value of the Premises as of<br \/>\nthe last day of the original Lease term or the first Renewal Term, as the<br \/>\ncase may be. The term fair market rental value of the Premises shall mean the<br \/>\nrental rate that a ready, willing, and able tenant would agree to pay to<br \/>\nlease the Premises then under this Lease, from a nonaffiliated landlord after<br \/>\narm&#8217;s length negotiations, assuming that neither this Lease nor any other<br \/>\nlease of the Premises were in effect. If the parties are unable to agree upon<br \/>\na fair market rental <\/p>\n<p>value within such fourteen (14) day period, Tenant shall, within seven (7)<br \/>\ndays of the expiration of such fourteen (14) day period, appoint an<br \/>\nappraiser, who shall be an M.A.I. real estate professional with at least two<br \/>\n(2) years experience in commercial real estate appraisal in Boulder County to<br \/>\ndetermine such fair market value, and shall give prompt written notice to the<br \/>\nLandlord identifying such appraiser. Said appraiser shall, within fifteen<br \/>\n(15) days following his or her appointment, render his or her report to<br \/>\nTenant. If Tenant accepts the fair market rental value reflected by such<br \/>\nreport, Tenant shall immediately provide a copy thereof to Landlord. If<br \/>\nTenant does not accept the value of such appraisal, it shall have an<br \/>\nadditional ten (10) days to obtain a second appraisal and shall immediately<br \/>\nprovide a copy thereof to Landlord. If Landlord does not accept and agree to<br \/>\nthe fair market rental value of the Premises as reflected in Tenant&#8217;s<br \/>\nappraisal, it shall notify Tenant of that fact within five (5) days following<br \/>\nreceipt of the Tenants appraisal report, and Landlord shall, within seven (7)<br \/>\ndays following rejection of the Tenant&#8217;s appraisal report, appoint an<br \/>\nappraiser with the qualifications set forth above, who shall independently<br \/>\nrender his or her opinion of the fair market rental value of the Premises<br \/>\nwithin fifteen (15) days after appointment. Failure of either party to<br \/>\nappoint an appraiser and to cause such appraiser to agree in writing to be<br \/>\nbound by the provisions of this Section within the respective seven (7) day<br \/>\nperiod shall be deemed to be an irrevocable election to accept the<br \/>\ndetermination of the fair market value made by the appraiser of the other<br \/>\nparty. Should Tenant reject the fair market rental value determined by<br \/>\nLandlord&#8217;s appraiser, and if the parties are unable to reach agreement upon<br \/>\nthe fair market rental value based upon the values reflected by the two<br \/>\nappraisals in hand, within seven (7) days after receipt of the Landlord&#8217;s<br \/>\nappraisal, the Tenant&#8217;s appraiser and the Landlord&#8217;s appraiser shall appoint<br \/>\na third, similarly-qualified appraiser, and cause such appraiser to agree in<br \/>\nwriting to be bound by the provisions of this Section, and give Landlord and<br \/>\nTenant written notice of his or her identify. In the event the Appraisers are<br \/>\nunable to agree on the third appraiser within said fourteen (14) day period,<br \/>\nthe parties hereto shall request that the President of the Boulder County Bar<br \/>\nAssociation (or such other individual as to whom the parties may agree)<br \/>\nappoint the third appraiser within seven (7) days. The third appraiser shall,<br \/>\nwithin fourteen (14) days of his appointment, express to both Landlord and<br \/>\nTenant his or her determination of the fair market rental value of the<br \/>\nDemised Premises, and such determination shall be determinative of the<br \/>\nDemised Premises&#8217; fair market rental value at such time, shall be final, and<br \/>\nshall govern for the purposes of this Section. If the appraisal procedure is<br \/>\nused, each party shall bear the cost of the appraiser appointed by it, and<br \/>\nthe parties shall share equally the cost of the third appraiser. If only one<br \/>\nappraiser shall be appointed, each party shall share equally the cost of such<br \/>\nappraiser. The three percent (3%) fixed annual increase in Base Rent provided<br \/>\nfor during the initial Lease Term shall apply during each Renewal Term.<\/p>\n<p>         40. RIGHT OF OPPORTUNITY ON ADDITIONAL SPACE:<\/p>\n<p>          Every instance of any equal or superior right of first opportunity<br \/>\ngiven by Landlord to any other tenant in the Building is listed on EXHIBIT F<br \/>\nto this Lease. Landlord will not grant any additional rights of opportunity<br \/>\nthat are equal or superior to Tenant&#8217;s rights, beyond those listed on Exhibit<br \/>\nF. Should Landlord become aware that additional space in the Building will<br \/>\nbecome available for lease, at any time during the term of this Lease,<br \/>\nLandlord agrees to provide to Tenant written notice of the availability of<br \/>\nsuch space, which notice shall identify the space, the date the same will be<br \/>\navailable <\/p>\n<p>for occupancy, and the rental rate which Landlord will offer such space for<br \/>\nrental to the public. Tenant shall have thirty (30) days following the<br \/>\neffective date of Landlord&#8217;s notice within which to notify Landlord that<br \/>\nTenant elects to rent such space, at the rental rate specified in Landlord&#8217;s<br \/>\nnotice, for a term concurrent with the Term of this Lease. Should Tenant fail<br \/>\nto give notice electing to rent such additional space within said thirty<br \/>\n(30)-day period, then Landlord may offer such space for lease to the public<br \/>\nand may lease the same at any time thereafter at a rental rate equal to or<br \/>\ngreater than 90% of the rental rate stated in the original notice from<br \/>\nLandlord to Tenant. If Landlord desires to lease such space at a rental rate<br \/>\nless than 90% of that stated in the notice to Tenant, Landlord shall once<br \/>\nagain offer the same to Tenant for a period of ten (10) days, at the lower<br \/>\nrental rate.<\/p>\n<p>                  IN WITNESS WHEREOF, Landlord and Tenant have executed this<br \/>\nLease the day and year first above written.<\/p>\n<p>                                       LANDLORD:<\/p>\n<p>                                       THW PARTNERS LIMITED PARTNERSHIP,<br \/>\n                                       a Colorado limited partnership<\/p>\n<p>                                       By: THW, Inc., a Florida corporation<br \/>\n                                           General Partner<\/p>\n<p>                                       By:<br \/>\n                                          &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;-<br \/>\n                                       Name:<br \/>\n                                            &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8211;<br \/>\n                                       Title:<br \/>\n                                             &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;-<\/p>\n<p>                                      TENANT:<\/p>\n<p>                                       GILEAD SCIENCES, INC.,<br \/>\n                                       a Delaware corporation<\/p>\n<p>                                       By:<br \/>\n                                          &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;-<br \/>\n                                       Name:<br \/>\n                                            &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8211;<br \/>\n                                       Title:<br \/>\n                                             &#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;&#8212;-<\/p>\n<p>                                   EXHIBIT &#8220;B&#8221;<\/p>\n<p>                                LEGAL DESCRIPTION<\/p>\n<p>                          Lot 2,<br \/>\n                          Center Green South, Replat A<br \/>\n                          Boulder County, Colorado<\/p>\n<p>                                   EXHIBIT &#8220;C&#8221;<\/p>\n<p>                   ESTOPPEL AND COMMENCEMENT DATE CERTIFICATE<\/p>\n<p>         THIS ESTOPPEL AND COMMENCEMENT DATE CERTIFICATE (&#8220;Certificate&#8221;) is<br \/>\nexecuted this ____ day of _____________, _____, by THW Partners Limited<br \/>\nPartnership, A Colorado limited partnership (&#8220;Landlord&#8221;) and Gilead Sciences,<br \/>\nInc.
