In the event that during all or any portion of any calendar year, the Building is not fully rented and occupied Landlord may make any appropriate adjustment in occupancy-related Operating Expenses for such year for the purpose of avoiding distortion of the amount of such Operating Expenses to be attributed to Tenant by reason of variation in total occupancy of the Building, by employing sound accounting and management principles to determine Operating Expenses that would have been paid or incurred by Landlord had the Building been 100% rented and occupied, and the amount so determined shall be deemed to have been Operating Expenses for such year. As used herein, the “Real Estate Tax Base” shall be $1.11 per rentable square foot times the rentable square feet contained within the Premises, and the “Operating Expense Base” shall be $3.84 per rentable square foot times the rentable square feet contained within the Premises.

If such statement shows that Tenant’s share of increases in Operating Expenses and Real Estate Taxes over the Operating Expense Base and the Real Estate Tax Base, respectively exceeds Tenant’s estimated monthly payments for the previous calendar year, then Tenant shall, within twenty (20) days after receiving Landlord’s certification, pay such deficiency to Landlord. In the event of an overpayment by Tenant, such overpayment (not to exceed the amount of the estimated payments) shall be refunded to Tenant, at the time of certification, in the form of an adjustment in the Additional Rental next coming due, or if at the end of the Term by a refund. By written notice given to Landlord no later than six (6) months following delivery of the written certification of Landlord, Tenant shall have the right to audit, or have audited the written certification and the books and records from which such certification is derived. Tenant shall pay the costs of any such audit, unless it is determined that Tenant’s overpayment was more than five percent (5%) of the actual amount in which case Landlord shall reimburse Tenant for the reasonable cost of the audit.

D. For purposes of this Article, the term “Real Estate Taxes” means the total of all taxes, fees, charges and assessments, general and special, ordinary and extraordinary, foreseen or unforeseen, which become due and payable upon the Building.

Electricity to the Premises shall be by separate submeter.

C. No temporary interruption or failure of such services incidental to the making of repairs, alterations or improvements, or due to accidents or strike or conditions or events not under Landlord’s control, shall be deemed as an eviction of the Tenant or relieve the Tenant from any of the Tenant’s obligations hereunder.

G. If the Tenant installs its own Tenant Generator, Tenant shall cooperate with the Landlord in load shedding and/or peak moving program when requested by the electric utility supplier (Northern States Power Company).

ARTICLE 10-NON-PERMITTED USE

A. Tenant agrees to use the Premises only for the purposes set forth in Article 2 hereof. Tenant further agrees not to commit or permit any act to be performed on the Premises or any omission to occur which shall be in violation of any statute, regulation or ordinance of any governmental body or which will increase the insurance rates on the Building or which will be in violation of any insurance policy carried on the Building by the Landlord.

Tenant agrees to indemnify and defend and hold Landlord harmless from and against all fines, suits, claims, actions, damages, liabilities, costs and expenses (including reasonable attorneys’ fees) asserted against Landlord arising out of and in any way connected with Tenant’s failure to comply with its obligations of this Paragraph or arising from the consented to presence of Hazardous Substances (specifically including any diesel fuel), which indemnification shall survive the expiration of the termination of this Lease Agreement.

Landlord agrees to indemnify and defend and hold Tenant

harmless from and against all fines, suits, claims, actions, damages, liabilities, costs and expenses (including attorneys’ fees) asserted by such governmental authorities against Tenant arising out of or in any way connected with Landlord’s failure to comply with its obligations in the preceding sentence, which indemnification shall survive the expiration or the termination of this Lease Agreement.

The Landlord or its employees or agents shall have the right without any diminution of rent or other charges payable hereunder by Tenant to enter the Premises at all reasonable times for the purpose of exhibiting the Premises to prospective tenants or purchasers, inspection, cleaning, repairing, testing, altering or improving the same or said Building, but nothing contained in this Article shall be construed so as to impose any obligation on the Landlord to make any repairs, alterations or improvements. Landlord’s rights under this section shall be exercised in such a manner as to create the least practicable interference with Tenant’s use and occupancy of the Premises. Except in the case of an emergency which makes notice to Tenant impractical, any entry on the Premises by Landlord shall be made at reasonable times after reasonable notice to Tenant. In exercising Landlord’s rights of entry, Landlord shall comply with Tenant’s reasonable security regulations of which Landlord has been advised of in writing. Landlord hereby recognizes that Tenant is engaged in a business that involves access to privileged and confidential matters and information and agrees to take reasonable precautions as to not compromise such confidentiality. Therefore Landlord agrees that Landlord may enter and pass through the Premises only when accompanied by a representative of Tenant, provided that Tenant agrees to make such representative available.

B. In addition to the Premises, Tenant shall have the right of non-exclusive use, in common with others, of (a) all unrestricted automobile parking areas, driveways and walkways, and (b) loading facilities, freight elevators and other facilities as may be constructed in the Building, all to be subject to the terms and conditions of this Lease Agreement and to reasonable rules and regulations for the use thereof as prescribed from time to time by Landlord.

Any restricted parking areas shall be leased only by separate license agreement with Landlord. Landlord agrees to provide Tenant, subject to availability, unassigned parking spaces pursuant to license agreements in the form of Exhibit C. The parking spaces being made available to Tenant pursuant to this Paragraph shall be made available at the commencement of the Term and continuing thereafter during the balance of the Term and Renewal Terms, but only to the extent Tenant continues the initial number of parking spaces continuously.

ARTICLE 15 - ASSIGNMENT AND SUBLETTING

A. Tenant agrees not to assign, sublet, license, or encumber this Lease Agreement, the Premises, or any part thereof, whether by voluntary act, operation of law, or otherwise without the specific prior written consent of Landlord; provided however, Landlord agrees not to unreasonably withhold, delay or deny such consent if: i) such assignment or sublease is in writing and the assignee or sublessee assumes all the obligations of Tenant under this Lease Agreement; ii) the proposed subtenant or assignee has a net worth of One Million Dollars ($1,000,000) or more at the time of such assignment or subletting; iii) the remaining provisions of this Lease Agreement continue to be applicable; and iv) Tenant shall remain liable hereunder.

of this Lease Agreement or sublease of the Premises to an “Affiliate” of Tenant or to any entity into or with which Tenant is merged or to the purchaser of all or substantially all the ownership interests or assets of Tenant; provided the survivor or transferee continues to operate the business of Tenant as a going concern. For purposes hereof an Affiliate shall mean any party that is “related to” Tenant as that term is defined by Sec. 267(b) of the Internal Revenue Code of 1986. Consent by Landlord in one such instance shall not be a waiver of Landlord’s rights under this Article as to requiring consent for any subsequent instance. In the event Tenant desires to sublet a part or all of the Premises, or assign this Lease Agreement, Tenant shall give written notice to Landlord at least thirty (30) days prior to the proposed subletting or assignment, which notice shall state the name of the proposed subtenant or assignee, the terms of any sublease or assignment documents and copies of financial reports or other relevant financial information of the proposed subtenant or assignee. At Landlord’s option, any and all payments by the proposed assignee or sublessee with respect to the assignment of sublease shall be paid directly to Landlord. In any event no subletting or assignment shall release Tenant of its obligation to pay the rent and to perform all other obligations to be performed by Tenant hereunder for the Term of this Lease Agreement. The acceptance of rent by Landlord from any other person shall not be deemed to be a waiver by Landlord of any provision hereof.

B. Notwithstanding anything to the contrary contained in this Article, Tenant may collaterally assign, mortgage, pledge, or hypothecate, without Landlord’s consent, its interest in this Lease Agreement to any financing entity, or agent on behalf of any financing entity to whom Tenant: i) has obligations for borrowed money or in respect of guarantees thereof, ii) has obligations evidenced by bonds, debentures, notes, or similar instruments, or iii) has obligations under or with respect to letters of credit, bankers’ acceptances and similar facilities or in respect of guarantees thereof.

C. Landlord’s right to assign this Lease Agreement is and shall remain unqualified upon any sale or transfer of the Building and, providing the purchaser succeeds to the interests of Landlord under this Lease Agreement and assumes the Landlord’s obligations hereunder, Landlord shall thereupon be entirely freed of all obligations of the Landlord accruing hereunder after such conveyance and shall not be subject to any liability resulting from any act or omission or event occurring after such conveyance.

ARTICLE 16 - LOSS BY CASUALTY

A. If the Building is damaged or destroyed by fire or other casualty, the Landlord shall have the right to terminate this Lease Agreement, provided it gives written notice thereof to the Tenant within ninety (90) days after such damage or destruction. If a portion of the Premises or Building is damaged by fire or other casualty, and in the reasonable opinion of Landlord: i) the Premises cannot be restored to tenantable condition within a period of ninety (90) days following the commencement of such restoration work, and/or ii) the cost of performing such restoration work exceeds the proceeds of Landlord’s casualty insurance by more than $100,000, then Landlord shall not be required to make any repairs and Landlord shall have the right to terminate this Lease, Agreement upon written notice to Tenant within thirty (30) days of the date of such fire or other casualty, in which event, this Lease Agreement shall terminate as of the date of such notice and Landlord and Tenant shall be released from any and all liability thereafter accruing hereunder. Landlord shall notify Tenant of its decision to rebuild or not within said thirty (30) day period. Anything herein to the contrary notwithstanding, if the

Premises are destroyed or so damaged that they cannot be repaired and made tenantable within ninety (90) days following commencement of such restoration work, or so damaged that Landlord shall decide not to repair or rebuild, or Landlord decides to repair or rebuild, or Landlord decides to repair or rebuild, but does not restore the Premises to a tenantable condition within ninety (90) days after commencement of such restoration work (subject to an extension of up to an additional sixty (60) days due to causes beyond Landlord’s control), then, in any of such instances, Tenant may terminate this Lease Agreement by giving notice to Landlord within thirty (30) days after Tenant’s receipt of Landlord’s notice or the expiration of said ninety (90) day period (as extended due to causes beyond Landlord’s control, as set forth above) as applicable, in which event this Lease Agreement shall terminate as of the date of such notice and Landlord and Tenant shall be released from any and all liability thereafter accruing hereunder. If this Lease Agreement has not been terminated by either Landlord or Tenant, then the rents due hereunder shall ▇▇▇▇▇ during such period of time as the Premises are untenantable, in the proportion that the untenantable portion of the Premises bears to entire Premises.

B. If the Premises are to be repaired under this Article 16, Landlord shall repair any injury or damage to the Building itself and the Premises in substantially the condition the Premises were in at the execution of this Lease Agreement, specifically excluding any leasehold improvements constructed by Tenant, Tenant’s Equipment or any Collateral, all of which shall be restored to the extent Tenant deems necessary, at Tenant’s sole cost and expense. Tenant shall, at its own cost and expense, remove all of its furniture and other personal property from the Premises as Landlord shall reasonably require in connection with its repair and restoration of the Premises under this Article 16.

ARTICLE 17 - WAVER OF SUBROGATION

Landlord and Tenant hereby release the other from any and all liability or responsibility to the other or anyone claiming through or under them by way of subrogation or otherwise for any loss or damage to property caused by fire or any of the extended coverage or supplementary contract casualties, even if such fire or other casualty shall have been caused by the fault or negligence of the other party, or anyone for whom such party may be responsible, provided however, that this release shall be applicable and in force and effect only with respect to loss or damage occurring during such times as the releasing party’s policies shall contain a clause or endorsement to the effect that any such release would not adversely affect or impair said policies or prejudice the right of the releasing party to recover thereunder. Landlord and Tenant agree that they will request their insurance carriers to include in their policies such a clause or endorsement. If extra cost shall be charged therefore, each party shall advise the other of the amount of the extra cost, and the other party, at its election, may pay the same, but shall not be obligated to do so.

ARTICLE 18 - EMINENT DOMAIN

If the entire Building is taken by eminent domain, this Lease Agreement shall automatically terminate as of the date of taking. If a portion of the Building is taken by eminent domain, the Landlord shall have the right to terminate this Lease Agreement, provided it gives written notice thereof to the Tenant within ninety (90) days after the date of taking. If a portion of the Premises is taken by eminent domain and this Lease Agreement is not terminated by Landlord, Tenant shall have the right to terminate this Lease Agreement, provided it gives written notice thereof to Landlord within ninety (90) days of the date of taking. If neither

Landlord nor Tenant terminates, then the Landlord shall, at its expense, restore the Premises to as near the condition which existed immediately prior to the date of taking as reasonably possible, and the rentals shall ▇▇▇▇▇ during such period of time as the Premises are untenantable, in the proportion that the untenantable portion of the Premises bears to the entire Premises. All damages awarded for such taking under the power of eminent domain shall belong to and be the sole property of Landlord, irrespective of the basis upon which they are awarded, provided, however, that nothing contained herein shall prevent Tenant from making a separate claim to the condemning authority for its moving expenses and trade fixtures. For purposes of this Article, a taking by eminent domain shall include Landlord’s giving of a deed under threat of condemnation, and shall be deemed to occur on the earlier of the date fee simple title has vested or possession has been obtained by the taking authority.

ARTICLE 19- SURRENDER

On the last day of the Term of this Lease Agreement or on the sooner termination thereof in accordance with the terms hereof, Tenant shall peaceably surrender the Premises in good condition and repair consistent with Tenant’s duty to make repairs as provided in Article 9 hereof. On or before said last day, Tenant shall at its expense remove all of its equipment from the Premises, repairing any damage caused thereby, and any property not removed shall be deemed abandoned, with the exception of any “Collateral” (as defined in Article 28 below) to the extent of any security interests by third parties. All alterations, additions and fixtures other than Tenant’s trade fixtures, which have been made or installed by either Landlord or Tenant upon the Premises shall remain as Landlord’s property and shall be surrendered with the Premises as a part thereof, or shall be removed by Tenant (unless such right to remove has been waived by Landlord pursuant to Article 4 above), in which event Tenant shall at its expense repair any damage caused thereby. It is specifically agreed that any and all telephonic, coaxial, ethernet, or other computer, word-processing, facsimile, or electronic wiring installed by Tenant within the Premises (hereafter “Wiring”) shall be removed at Tenant’s cost at the expiration of the Term, unless Landlord has specifically requested in writing that said Wiring shall remain, whereupon said Wiring shall be surrendered with the Premises as Landlord’s property. If the Premises are not surrendered at the end of the Term or the sooner termination thereof; Tenant shall indemnify Landlord against loss or liability resulting from delay by Tenant in so surrendering the Premises, including, without limitation, claims made by any succeeding tenant founded on such delay. Tenant shall promptly surrender all keys for the Premises to Landlord at the place then fixed for payment of rental and shall inform Landlord of combinations on any locks and safes on the Premises.

ARTICLE 20 - NON-PAYMENT OF RENT, DEFAULTS

If any one or more of the following occurs: (1) a rent payment or any other payment due from Tenant to Landlord shall be and remain unpaid in whole or in part for more than ten (10) days after same is due and payable; (2) Tenant shall violate or default on any of the other covenants, agreements, stipulations or conditions herein, or in any parking agreement(s) or other agreements between Landlord and Tenant relating to the Premises, and such violation or default shall continue for a period of thirty (30) days after written notice from Landlord of such violation or default or if such violation or default shall reasonably require longer than thirty (30) days to cure, if Tenant shall fail to commence the cure of such default or violation within thirty (30) days after receipt of notice thereof and/or fail to prosecute a cure to completion with due diligence; (3) if Tenant shall commence or have commenced against Tenant proceedings under a

bankruptcy, receivership, insolvency or similar type of action; or (4) if Tenant shall abandon the Premises; then it shall be optional for Landlord, without further notice or demand, to cure such default or to declare this Lease Agreement forfeited and the said Term ended, or to terminate only Tenant’s right to possession of the Premises, and to re-enter the Premises, with or without process of law, using such force as may be necessary to remove all persons or chattels therefrom, and Landlord shall not be liable for damages by reason of such re-entry or forfeiture; but notwithstanding re-entry by Landlord or termination only of Tenant’s right to possession of the Premises, the liability of Tenant for the rent and all other sums provided herein shall not be relinquished or extinguished for the balance of the Term of this Lease Agreement and Landlord shall be entitled to periodically ▇▇▇ Tenant for all sums due under this Lease Agreement or which become due prior to judgment, but such suit shall not bar subsequent suits for any further sums coming due thereafter. Tenant shall be responsible for, in addition to the rentals and other sums agreed to be paid hereunder, the cost of any necessary maintenance, repair, restoration, reletting (including related cost of removal or modification of tenant improvements) or cure as well as reasonable attorney’s fees incurred or awarded in any suit or action instituted by Landlord to enforce the provisions of this Lease Agreement, regain possession of the Premises, or the collection of the rentals due Landlord hereunder. Tenant shall also be liable to Landlord for the payment of a late charge in the amount of 5% of the rental installment or other sum due Landlord hereunder if said payment has not been received within ten (10) days from the date said payment becomes due and payable, or cleared by Landlord’s bank within three (3) business days after deposit. Tenant agrees to pay interest at the highest permissible rate of interest allowed under the usury statutes of the State of Minnesota, or in case no such maximum rate of interest is provided, at the rate of 12% per annum, on all rentals and other sums due Landlord hereunder not paid within ten (10) days from the date same become due and payable. Each right or remedy of Landlord provided for in this Lease Agreement shall be cumulative and shall be in addition to every other right or remedy provided for in this Lease Agreement now or hereafter existing at law or in equity or by statute or otherwise.

ARTICLE 21- LANDLORD’S DEFAULT

Landlord shall not be deemed to be in default under this Lease Agreement until Tenant has given Landlord written notice specifying the nature of the default and Landlord does not cure such default within thirty (30) days after receipt of such notice or within such reasonable time thereafter as may be necessary to cure such default where such default is of such a character as to reasonably require more than thirty (30) days to cure.

ARTICLE 22 - HOLDING OVER

Tenant will, at the expiration of this Lease Agreement, whether by lapse of time or termination, give up immediate possession to Landlord. If Tenant fails to give up possession Landlord may, at its option, serve written notice upon Tenant that such holdover constitutes any one of (i) creation of a month to month tenancy, or (ii) creation of a tenancy at sufferance. If Landlord does not give said notice, Tenant’s holdover shall create a tenancy at sufferance. In any such event the tenancy shall be upon the terms and conditions of this Lease Agreement, except that the Minimum Rental shall be 150% the Minimum Rental Tenant was obligated to pay Landlord under this Lease Agreement immediately prior to termination (in the case of tenancy at sufferance such Minimum Rental shall be prorated on the basis of a 365 day year for each day Tenant remains in possession); excepting further that in the case of a tenancy at sufferance, no notices shall be required prior to commencement of any legal action to gain repossession of the

Premises. In the case of a tenancy at sufferance, Tenant shall also pay to Landlord all damages sustained by Landlord resulting from retention of possession by Tenant, provided such damages shall not include consequential damages if such holdover is for five (5) business days or less. The provisions of this paragraph shall not constitute a waiver by Landlord of any right of re-entry as otherwise available to Landlord; nor shall receipt of any rent or any other act in apparent affirmance of the tenancy operate as a waiver of the right to terminate this Lease Agreement for a breach by Tenant hereof.

ARTICLE 23 - SUBORDINATION

Tenant agrees that this Lease Agreement shall be subordinate to any mortgage(s) that may now or hereafter be placed upon the Building or any part thereof, and to any and all advances to be made thereunder, and to the interest thereon, and all renewals, replacements, and extensions thereof and to execute a specific subordination agreement (in a form reasonably requested by mortgagee) if so requested by Landlord, provided the mortgagee named in such subordination shall agree to recognize this Lease Agreement or Tenant in the event of foreclosure provided the Tenant is not in default by including non-disturbance language, in recordable form. In the event of any mortgagee electing to have the Lease Agreement a prior encumbrance to its mortgage, then and in such event upon such mortgagee notifying Tenant to that effect, this Lease Agreement shall be deemed prior in encumbrance to the said mortgage, whether this Lease Agreement is dated prior to or subsequent to the date of said mortgage. Landlord shall use its best efforts to obtain a non-disturbance agreement from the existing mortgagee (the Federal Deposit Insurance Corporation) and any future mortgagees, in a form reasonably satisfactory to such mortgagee and Tenant.

ARTICLE 24 - INDEMNITY, INSURANCE AND SECURITY

A. Tenant will keep in force at its own expense for so long as this Lease Agreement remains in effect public liability insurance with respect to the Premises in which Landlord shall be named as an additional insured, in companies and in form acceptable to Landlord with a minimum combined limit of liability of Two Million Dollars ($2,000,000.00). This limit shall apply per location. Said insurance shall also provide for contractual liability coverage by endorsement.

ARTICLE 32 - GENERAL

This Lease Agreement does not create the relationship of principal and agent or of partnership or of joint venture or of any association between Landlord and Tenant, the sole relationship between Landlord and Tenant being that of landlord and tenant. No waiver of any default of Tenant hereunder shall be implied from any omission by Landlord to take any action on account of such default if such default persists or is repeated, and no express waiver shall affect any default other than the default specified in the express waiver and that only for the time and to the extent therein stated. The covenants of Tenant to pay the Minimum Rental and the Additional Rental are each independent of any other covenant, condition, or provision contained in this Lease Agreement. The marginal or topical headings of the several Articles, paragraphs and clauses are for convenience only and do not define, limit or construe the contents of such Articles, paragraphs or clauses. All preliminary negotiations are merged into and incorporated in this Lease Agreement. This Lease Agreement can only be modified or amended by an agreement in writing signed by the parties hereto. All provisions hereof shall be binding upon the heirs, successors and assigns of each party hereto. If any term or provision of this Lease Agreement shall to any extent be held invalid or unenforceable, the remainder shall not be affected thereby,

and each other term and provision of this Lease Agreement shall be valid and be enforced to the fullest extent permitted by law. If Tenant is a corporation, each individual executing this Lease Agreement on behalf of said corporation represents and warrants that he is duly authorized to execute and deliver this Lease Agreement on behalf of said corporation in accordance with a duly adopted resolution of the Board of Directors of said corporation or in accordance with the Bylaws of said corporation, and that this Lease Agreement is binding upon said corporation in accordance with its terms. No receipt or acceptance by Landlord from Tenant of less than the monthly rent herein stipulated shall be deemed to be other than a partial payment on account for any due and unpaid stipulated rent; no endorsement or statement of any check or any letter or other writing accompanying any check or payment of rent to Landlord shall be deemed an accord and satisfaction, and Landlord may accept and negotiate such check or payment without prejudice to Landlord’s rights to (i) recover the remaining balance of such unpaid rent or (ii) pursue any other remedy provided in this Lease- Agreement. Either party may record a memorandum of this Lease Agreement and the parties agree to execute a reasonable form memorandum as presented by the other party. Time is of the essence with respect to the due performance of the terms, covenants and conditions herein contained. Submission of this instrument for examination does not constitute a reservation of or option for the Premises, and this Lease Agreement shall become effective only upon execution and delivery thereof by Landlord and Tenant.

ARTICLE 33 - QUIET ENJOYMENT

Landlord covenants that Tenant, upon paying the rental and other charges due hereunder and performing all of Tenant’s obligations under this Lease Agreement, shall peacefully and quietly hold, occupy and enjoy Premises throughout the Term hereof, without molestation or hindrance by any person holding, under or through Landlord, subject, however, to the provisions of this Lease Agreement and to any mortgages or ground or underlying leases referred to in Article 23 hereof. Any diminution or shutting off of light, air or view by any structure which may be erected on lands adjacent to the Building shall in no way affect this Lease Agreement or impose any liability on Landlord.

ARTICLE 34 - LIMITED EXPANSION RIGHT

A. Provided Tenant is not then in default under this Lease Agreement beyond the applicable grace period, Tenant shall have a right of leasing space contiguous to the Premises on the third floor of the Building (hereafter referred to as the “Option Space”), in the event such Option Space becomes “Available for Leasing” (as defined below) during the original Term, subject to and conditioned upon the provisions of this Article (the “Expansion Right”).

B. Landlord shall notify Tenant (“Landlord’s Notice”) in the event the Option Space becomes “Available for Leasing”; or in the event Landlord has a third party interested in leasing the Option Space which is then “Available for Leasing”. Tenant shall notify Landlord (“Tenant’s Leasing Notice”) within five (5) business days after its receipt of Landlord’s Notice as to whether Tenant intends to exercise its Expansion Right with respect to said Option Space as so identified in Landlord’s Notice, time being of the essence. If Tenant exercises its Expansion Right, it must do so with respect to all the Option Space as so identified in Landlord’s Notice. In such event, Landlord and Tenant shall execute an amendment to the Lease Agreement incorporating the Option Space as so identified into the Premises at the Minimum Rent at the then applicable rates as set forth in the table of Paragraph 3B above. In the

event Tenant fails to notify Landlord within the time period set forth above, Tenant’s rights under this Article shall be null and void with respect to any lease entered into with respect to the original prospective Tenant for the Option Space as so identified in Landlord’s Notice; provided such Expansion Right shall again be applicable in the event Landlord does not lease such Option Space to the original prospective Tenant within nine (9) months of the Landlord’s Notice.

C. Tenant’s Expansion Right shall also include Tenant’s providing Landlord a Tenant’s Leasing Notice (in the first instance and not in response to a Landlord’s Notice) with respect to the Option Space which is then “Available for Leasing” provided no Landlord’s Notice has been given to Tenant with respect to any portion of such Option Space within the previous nine (9) months.

D. The leasing of said Option Space shall commence as of the “Effective Date” (as set forth below) and shall be in said Option Space’s, then “AS-IS” condition without any improvements, improvement allowances or other modifications to be made by Landlord. For purposes of this Article, the “Effective Date” shall mean the date on which Tenant shall begin paying rentals upon the Option Space after it has exercised its rights to said space; which shall be thirty (30) days after Tenant’s Leasing Notice under this Article to Landlord exercising its rights hereunder (or such sooner date as Tenant takes possession and commences its business operations from within the Option Space). The provisions of this Lease Agreement governing alterations of the Premises shall apply with respect to the construction of any leasehold improvements Tenant desires to make to such Option Space.

E. Notwithstanding anything to the contrary in the foregoing, if Tenant exercises its rights under this Article and there remains less than thirty-six (36) months from the Effective Date to the expiration of the Term, then the Tenant shall not be entitled to exercise its rights under this Article unless it exercises its Option to Renew the Term, or if no such Option to Renew can then be exercised, then Tenant shall no longer have any rights under this Article with respect to the Option Space.

F. For purposes of this Article, “Available for Leasing” shall mean the Option Space is not subject to any existing (as of the date of this Lease Agreement) lease or first rights of refusal, first rights of negotiation, first rights of leasing, expansion rights, renewal rights and/or similar rights of any other third party tenant or such rights have been waived in writing (provided if all such rights are to expire within six (6) months, Landlord may make such Option Space Available for Leasing contingent upon the expiration of such rights). In any event Landlord shall be entitled to renew or extend any lease of an “Occupying Third Party” (as defined below), without providing Tenant a Landlord’s Notice and without it being subject to any rights of a third party under this Article. Tenants which are either presently occupying Option Space or may be so occupying in the future pursuant to a third party lease which was entered into after Tenant’s rights were waived or deemed waived pursuant to Paragraph B of this Article shall be deemed to be an “Occupying Third Party”.

G. If the Lease Agreement or Tenant’s right to possession of the Premises shall terminate in any manner whatsoever before Tenant shall exercise its rights under this Article, or if Tenant shall have subleased or assigned all or any portion of the Premises, then immediately upon such termination, sublease, or assignment, then this Article and Tenant’s rights

hereunder shall simultaneously terminate and become null and void. Such right is personal to Tenant Under no circumstances whatsoever shall the assignee under a complete or partial assignment of the Lease, or a subtenant under a sublease of the Premises, have any right to exercise any rights under this Article or have any right to receive any Landlord’s Notice.

ARTICLE 35 - CANCELLATION RIGHT

A. Tenant shall have two separate rights to notify Landlord, that it elects to terminate this Lease as of the end of the sixtieth (60th) or the eighty-fourth (84) month of the Term, subject to and conditioned upon the following conditions:

i. Tenant shall give Landlord written notice of Tenant’s intention to terminate this Lease not less than six (6) months prior to either the fifth (5th) or the seventh (7) anniversaries of the Term, in accordance with the notice provisions set forth above (“Termination Notice”);

ii. The Termination Notice shall set forth the effective date for said termination (“Termination Date”) which date shall be midnight of the day prior to: i) the fifth (5th) anniversary of the Term (if the Termination Notice is given prior to the fifty-fourth (54th) month of the Term), or ii) the seventh (7th) anniversary of the Term (if the Termination Notice is given after the fifty-fourth (54th) month but prior to the seventy-eighth (78th) month of the Term);

iii. Tenant must not be in default either at the time of the Termination Notice nor at the Termination Date and Tenant must comply with all of the terms and conditions of this Lease Agreement (including surrender of the Premises as required by this Lease Agreement) through the Termination Date;

iv. Tenant must accompany said Termination Notice with a “Termination Fee”, which shall be equal to six (6) months rental which would otherwise have been due under this Lease Agreement immediately following the Termination Date.

v. In no event shall Tenant be entitled to terminate this Lease if it has exercised its rights to renew under Article 1 above.

B. The rights provided to Tenant under this Article are personal to Tenant, which may assign them only in connection with an assignment of this Lease Agreement to a company controlled by or which controls (directly or indirectly) Advanced Telecommunications, Inc. (“Affiliate”), and such rights shall expire automatically if Tenant assigns this Lease Agreement to any other party or subleases all or any portion of the Premises to any other party.

C. Tenant’s rights under this Article may be exercise only once, but at either of the two (2) time periods set forth above.

D. Notwithstanding anything contained in this Article to the contrary, if Tenant exercises its Expansion Right pursuant or in response to a “Landlord’s Notice” (as defined in Paragraph 34B above), then Tenant’s right to give a Termination Notice under this Article shall be suspended for a period commencing with Tenant’s giving of its “Tenant’s Leasing Notice” (as defined in Paragraph 34B above) and continuing through the 18th month subsequent to the “Effective Date” (as defined in Paragraph 34D above). Any Termination Notice given during such period shall be of no effect and shall not result in the termination of this Lease Agreement.

The restrictions of this Paragraph, and specifically the suspension of Tenant’s right to give a Termination Notice under this Article shall not become applicable if Tenant exercises its Expansion Right pursuant to Paragraph 35C above (i.e. Tenant shall continue to have the rights to terminate under this Article if Tenant’s expansion was not in response to a “Landlord’s Notice”).

IN WITNESS WHEREOF, this Lease Agreement has been duly executed by the parties hereto as of the day and year indicated above.

ANTENNAE LICENSE AGREEMENT

This License Agreement (the “Agreement”), dated as of this 3rd day of March, 1999, is between TIMESHARE SYSTEMS, INC. (the “Licensor”), having an address at ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇, ▇▇. ▇▇▇▇▇ and ADVANCED TELECOMMUNICATIONS, INC. (the “Licensee”), having an address at ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇, ▇▇. ▇▇▇▇▇ (the “Premises”).

A. Licensor agrees to permit Licensee to utilize for purposes provided herein, the roof space (the exact location to be determined by Licensor with the reasonable consent of Licensee, but in no event shall such space exceed 100 contiguous square feet) on the building (“Building”) in which the Premises are located (the “Roof Space”), from the date hereof and expiring April 30, 2099. Upon termination of Licensee’s lease for the Premises for any reason (including the failure to renew the Term), this License Agreement and the license created hereby shall automatically expire with said termination. The termination, cancellation or expiration of this License Agreement or the license created hereunder shall not be cause or grounds for the cancellation or termination of Licensee’s lease for the Premises.

H. Licensee may install, use and maintain on such Roof Space equipment (“Equipment”) as described in Exhibit A attached hereto. If so requested by Licensor, Licensee shall, at its sole expense, install a screening and protective fence (“Fence”) around the perimeter of the Roof Space. The Fence style and installation shall be subject to Licensor’s prior approval.

I. Licensor agrees that Licensee may run cables (the “Cables”) between the Roof Space and the Licensee’s Premises. Any damages to the Building or fixtures or equipment located upon or within the Building resulting therefrom shall be promptly repaired by Licensee.

J. The Equipment and Fence shall remain the property of the Licensee or its contractor. Licensee shall at its cost remove such Equipment and Fence (and if so requested by Licensor, the Cables) at the expiration or sooner termination of the license granted hereunder or this License Agreement, and restore the Roof Space and Building to the condition they were in prior to Licensee’s installation of the Equipment, Fence and Cables. The obligations to remove the Equipment, Fence and Cables and to restore and repair the Roof Space and Building shall survive the expiration or sooner termination of the license and this License Agreement.

K. Licensee and/or its contractor shall bear all expenses in connection with the installation; use and maintenance of such Equipment, Fence and Cables and removal of the same. Licensee shall indemnify and hold Licensor harmless from and against liability, damages, costs and expenses, including reasonable attorneys’ fees incurred by Licensor, arising out of Licensee’s installation, use, maintenance and removal of the Equipment, Fence and Cables. This obligation shall survive the expiration, cancellation or termination of this License Agreement and the license created hereunder.

L. Licensee and/or its contractor shall maintain in force during the term of this License Agreement comprehensive liability insurance in amounts and in such form as reasonably satisfactory to Licensor, protecting Licensor against any liability, damages, cost or

B-1

expenses, in connection with the installation, use, maintenance and removal of the Equipment, Fence and Cables and shall supply the appropriate certificates of such insurance upon request.

M. Licensee and its contractors shall comply with all applicable federal, state and local laws, regulations, and building codes in connection with the installation, use, maintenance and removal of the Equipment, Fence and Cables. In the event any such laws, regulations, or codes requires physical improvements be made to the Building or other expenditures by or on behalf of the Building and/or its owner, the costs of the same shall be borne by Licensee. Notwithstanding the foregoing, any physical improvements, whether required by law, regulation, code or otherwise, shall be subject to Licenser’s approval, which approval may be given or denied in Licensor’s sole discretion. If any law, regulation or code prohibits or disallows the Equipment, Fence and/or Cables or the effective use of the license granted hereby, whether now or in the future, Licensor shall be entitled to terminate the license granted hereby, without penalty; and Licensee shall take such action so as to allow the Building to again be in compliance with such law, regulation or code, including, if necessary, the removal of the Equipment, Fence and/or Cables.

N. Licensor agrees to permit Licensee reasonable access to the Roof Space and other areas so as to facilitate the installation, use, maintenance and removal of the Equipment, Fence, and Cables. Licensee shall have access to the Roof Space on a 24 hour per day, 7 days per week basis, in order to facilitate maintenance and repairs. Licensee agrees to sign the Building’s log book on each occasion Licensee enters the Roof Space, during normal business hours. At times other than normal business hours, or when the log book is not available for signing, Tenant shall page Landlord at 470-4500 or shall leave a message by calling 481-9999 or shall notify Landlord by such other reasonable means as Landlord shall inform Tenant in writing.

O. Notwithstanding anything else contained herein to the contrary, the license granted herein is subject to the non-interference of Licensee’s Equipment with the normal operation, functioning and use of any other equipment (whether owned by Licensor or by other licensees and/or tenants of Licensor) currently existing upon the roof of the Building. In the event of any such interference, Licensor may terminate the License granted hereunder if such interference is not corrected within three (3) days notice from Licensor to Licensee. Notwithstanding anything else contained herein to the contrary, Licensor does not guaranty nor warrant the reception, noninterference or effective use of Licensee’s antenna, or Equipment, either at initial installation nor thereafter.

P. Licensee shall be required to get prior approval from Licensor pertaining to the Antenna size, color, Fence specifications, location on roof; method of mounting and the location of all Cables. In no instance shall this installation breach or penetrate the roof membrane.

Q. Any notice required or desired under this License Agreement shall be deemed sufficiently given if given in compliance with the Licensee’s lease agreement for the Premises.

B-2

R. Licensee shall pay to Licensor, without set-off or demand the sum of $0 per month for all Antennae (as listed on Exhibit A, or otherwise located on the Building pursuant to this License Agreement or the license created hereunder) for use of the roof space (“License Fee”) during the Term of this License Agreement. Failure by Licensee to pay said License Fee shall entitle Licensor, upon 10 days written notice to Licensee, to terminate this License Agreement and the license created hereunder, and to such other relief as may be allowed by law or equity. No other Equipment or antennae shall be permitted by this license, without Licensor’s prior written consent, which consent shall not be unreasonably withheld for a reasonable increase in equipment, provided the License Fee shall be increased to Licensor’s then rate for each additional antennae.

S. In the event of default by Licensee of any of the terms and conditions set forth in this License Agreement, whether suit be commenced or not, Licensee agrees to pay the attorneys’ fees, costs and expenses of Licensor incurred in enforcing or attempting to enforce this License Agreement.

T. Licensee shall operate the Licensee facilities in a manner that will not cause interference to Licensor and other Licensees of the Property provided that their installations predate that of the Licensee’s facilities.
