If Landlord shall consent, all Tenant’s Changes shall comply, whether structural or non-structural, with the following conditions: (a) such changes will not result in a violation of or require a change in the Certificate of Occupancy applicable to the Demised Premises, unless Tenant shall have obtained the same or shall covenant to do so and provide to Landlord such bond or other security as it shall require; (b) the outside appearance, character or use of the Demised Premises or the Building shall not be affected, and no Tenant’s Changes shall weaken or impair the structural strength or lessen the value of the Building; (c) the proper functioning of any of the mechanical, electrical, sanitary and other service systems of the Building shall not be adversely affected; (d) in performing the work involved in making such changes, Tenant shall be bound by and observe all of the conditions and covenants contained in this Article and in Article 33; (e) at the Expiration Date, Tenant shall on Landlord’s written request restore the Demised Premises to their condition prior to the making of any changes permitted by this Article, reasonable wear and tear excepted, unless at the time of granting of Landlord’s consent, such requirement was waived by Landlord; (f) before proceeding with any change Tenant shall submit to Landlord plans and specifications for the work to be done, and shall request Landlord’s approval in writing, and, if such change requires approval by or notice to the lessor of a superior lease or the holder of a superior mortgage, Tenant shall not proceed with the change until such approval has been received, or such notice has been given, as the case may be, and all applicable conditions and provisions of said superior lease or superior mortgage with respect to the proposed change or alteration have been met or complied with at Tenant’s expense (including, without limitation, all costs

10

incurred by Landlord in reviewing and analyzing Tenant’s request for changes); and Landlord, if it approves the change (only if Landlord’s approval is required in accordance with the foregoing), will request such approval or give such notice, as the case may be; any change for which approval has been received shall be performed strictly in accordance with the approved plans and specifications, and no substantial amendments or additions to such plans and specifications shall be made without the prior written consent of Landlord; and Tenant shall not be permitted to install and make a part of the Demised Premises any materials, fixtures or articles which are subject to liens, conditional sales contracts, security agreements or chattel mortgages; (g) Tenant shall not interfere with the access or egress of other tenants nor otherwise interfere with the peaceful use of the Building by such other tenants; and (h) Tenant shall comply with all other terms and conditions of this Lease in connection with Tenant’s Changes. Neither approval of the plans and specifications nor supervision of the alteration by the Landlord shall constitute a representation or warranty by Landlord as to the accuracy, adequacy, sufficiency, or propriety of such plans and specifications or the quality of workmanship or the compliance of such alteration with applicable law. Tenant shall pay the entire cost of the alteration and, if requested by Landlord, and if such cost shall exceed $25,000, Tenant shall deposit with Landlord prior to the commencement of the alteration, the full cost of such improvement in form and amount required by Landlord and/or its lender. As construction is completed, Tenant may direct Landlord to disburse such sums from said deposit based upon Landlord’s architect’s or engineer’s certification of the percentage of completion. All costs of the foregoing shall be borne by Tenant.

8.02 All Tenant’s Changes shall at all times comply with laws, orders and regulations of governmental authorities having jurisdiction thereof, and all rules and regulations of Landlord, and Tenant, at its expense, shall obtain all necessary governmental permits and certificates for the commencement and prosecution of Tenant’s Changes and for final approval thereof upon completion, and shall cause Tenant’s Changes to be performed in compliance therewith and with all applicable requirements of insurance bodies, and in good and first class workmanlike manner, using materials and equipment of at least first class quality. Throughout the performance of Tenant’s Changes, Tenant, at its expense, shall carry, or cause to be carried, worker’s compensation insurance in statutory limits, and general liability insurance for any occurrence on, in or about the Demised Premises, of which Landlord, managing agent and any mortgagee shall be named as parties insured, in such limits as Landlord may reasonably prescribe (but not less than those specified in Article 11), with insurers admitted to do business in the State of New York having a rating of no less than “A/10” in the most current edition of Bests Key Rating Guide. Tenant shall furnish Landlord with reasonably satisfactory evidence that such insurance is in effect at or before the commencement of Tenant’s Changes and, on request, at reasonable intervals thereafter during the continuance of Tenant’s Changes. No Tenant’s Changes shall involve the removal of any fixtures, equipment or other property in the Demised Premises, unless such fixtures, equipment or other property shall be promptly replaced, at Tenant’s expense and free of superior title, liens and claims, with fixtures, equipment or other property (as the case may be) of like utility and at least equal value acceptable to Landlord (which replaced fixtures, equipment or other property shall thereupon become the property of Landlord), unless Landlord shall otherwise expressly consent in writing.

8.03 Tenant, at its expense, and with diligence and dispatch, shall procure the cancellation or discharge of all notices of violation arising from or otherwise connected with Tenant’s Changes which shall be issued by the appropriate department of the municipality where the Building is located or any other public authority having or asserting jurisdiction. Upon completion of any Tenants Changes, Tenant shall promptly furnish Landlord with sworn owner’s and contractor’s statements and full and final waivers of lien covering all labor and materials included in such Tenant’s Changes, Tenant shall not permit any mechanics lien to be filed against the Building, or any part thereof, arising out of any Tenant’s Changes performed, or alleged to have been performed, by or on behalf of Tenant. Tenant shall defend, indemnify and save harmless Landlord against any and all mechanics and other liens in connection with Tenant’s Changes, repairs or installations, including but not limited to the liens of any conditional sales of, or chattel mortgages upon, any materials, fixtures, or articles so installed in and constituting part of the Demised Premises and against all costs, attorney’s fees, fines,

11

expenses and liabilities reasonably incurred in connection with any such lien, conditional sale or chattel mortgage or any action or proceeding brought thereon. Tenant, at its expense, shall commence the necessary proceedings to procure the satisfaction or discharge of all such liens within ten (10) days of the filing of such lien against the Demised Premises or the Building and shall, within the minimum time period possible under the laws of the State of New York, cause such lien to be discharged. If Tenant shall fail to comply with the foregoing requirements within the aforesaid time periods, then, in addition to any other right or remedy, Landlord may, but shall not be obligated to, discharge the same either by paying the amount claimed to be due or by procuring the discharge of such lien by deposit or by bonding proceedings. If Landlord is required to make any repairs or perform any maintenance or do any work of any nature whatsoever with respect to Tenant’s Changes, then Tenant shall pay to Landlord immediately upon demand the cost of any such repairs or maintenance as Additional Rent. However, nothing herein shall be construed to impose a duty on Landlord to mitigate its damages by undertaking any repair which is Tenant’s obligation.

ARTICLE 9

Personal Property

9.01 All fixtures, equipment, improvements and appurtenances attached to or built into the Demised Premises at the Commencement Date or during the Term, whether or not by or at the expense of Tenant, shall be and remain a part of the Demised Premises, shall be deemed the property of Landlord and shall not be removed by Tenant except as hereinafter in this Article expressly provided. Tenant shall remove all of Tenant’s medical equipment and accessories, machines and trade fixtures (including, without limitation, all medical equipment or machines bolted to the floor) on the Expiration or earlier termination of this Lease, provided that it restore the Demised Premises as provided in Article 19 hereof.

9.02 All items of Personal Property, or of the type or nature similar to items of Personal Property, may be used by Tenant and, if consumable, consumed by Tenant in the operation of the Demised Premises for the permitted use. If Tenant desires to replace any non-consumable items of Personal Property, it may do so subject to Landlord’s prior written consent which Landlord shall not unreasonably withhold or delay, provided that Tenant shall replace such items with others of at least equal quality and value.

ARTICLE 10

Repairs and Maintenance

10.01 Tenant shall, at all times during the Term, at its sole cost and expense, maintain the Demised Premises in good first class order and shall provide all cleaning and janitorial service to the Demised Premises, including among other things the cleaning of exterior windows, necessary to maintain the same in such first class order. Tenant, at Tenant’s sole cost and expense, shall make all necessary repairs to the Demised Premises, of whatever nature other than structural repairs referred to below, including but not limited to interior and exterior, extraordinary as well as ordinary, foreseen or unforeseen, and will keep all improvements and the fixtures, machinery and equipment located in or on the Demised Premises, or servicing the same and every part thereof in good first class order and repair. Tenant shall be solely responsible for the maintenance, repair and/or replacement of any computer, communications, plumbing fixtures, heating, ventilating and air conditioning units and similar equipment installed by Tenant or at its request, whether or not located in the Demised Premises. Landlord shall have no duty whatsoever to make any repairs to the Demised Premises, or to the fixtures, machinery and equipment located thereon or serving the same, during the Term of this Lease or any Option Term thereof. Landlord shall make structural repairs to the Building and the Demised Premises which in its reasonable judgement are

12

necessary, and the same shall be added to Landlord’s Costs of Operation. If any part of the Demised Premises shall be damaged solely by the negligence of the Landlord, its agents or employees, then Landlord shall repair such damage at its sole cost and expense.

10.02 In the event Tenant defaults in making any repairs to, or maintenance of, the Demised Premises and, at its option, Landlord elects to make such repairs (at the expense of Tenant and subject to any other terms of this Lease) during Tenant’s continued occupancy of the Demised Premises (which election shall not waive any other rights Landlord may have hereunder, including, but not limited to, the right of eviction), Landlord shall have no liability to Tenant by reason of any inconvenience, annoyance, interruption or injury to Tenant’s business arising from Landlord making said repairs. Tenant shall pay to Landlord, immediately upon demand, and as Additional Rent, the cost of any repairs or maintenance performed by Landlord which are the responsibility of Tenant under this Lease. Nothing contained in this paragraph shall be construed to impose upon Landlord any duty to mitigate damages which might be incurred by it.

10.03 When used in this Lease the term “repair” shall be deemed to include restoration and replacement as may be necessary to achieve and/or maintain good working order and condition consistent with comparable buildings in the Mount Kisco, New York area.

ARTICLE 11

Insurance

11.01 Tenant, at its own cost and expense, shall procure and maintain for the mutual benefit of, and naming Landlord, Landlord’s Managing Agent, Landlord’s mortgagee and Tenant, commercial general liability insurance in an amount not less than $10,000,000 combined single limit of liability, on an occurrence basis, for bodily injury, death and property damage arising out of any one occurrence occurring in, upon, adjacent, or connected with the Demised Premises or any part thereof and, from time to time during the Term, for such higher limits, if any, as are currently carried with respect to similar properties in the area where the Demised Premises are located.

11.02 (A) Tenant at its own cost and expense, during the Term, shall keep the leasehold improvements on the Demised Premises together with all other betterments and improvements forming part of the Demised Premises, and all personal property including without limitation, all machinery and equipment, whether or not attached to or affixed to the Building {“Tenant’s Assets”), insured against loss or damage by fire and such other risks as are from time to time customarily included in the broad form of extended coverage endorsements (commonly known as “all risk” endorsements) attached to the fire insurance policies in the State of New York, with insurers admitted to do business in the State of New York having a rating of no less than “A/10” in the most current edition of Bests Key Rating Guide, in an amount sufficient to prevent the assured from becoming a co-insurer within the terms of the applicable policies, but in any event in an amount not less than one hundred (100%) percent of the full replacement cost of Tenant’s Assets.

(B) The term “replacement cost” shall mean the full cost of repair or replacement of Tenant’s Assets, without deduction for depreciation.

(C) If Landlord claims that the amount of fire insurance carried by Tenant is not sufficient to cover the replacement cost of Tenant’s Assets as from time to time existing, then Tenant, at the request of Landlord, shall obtain a written appraisal of the insurance company or companies underwriting the risk or of a party acceptable to such company or companies and the replacement cost as given in said appraisal shall be deemed the replacement cost of the Tenant’s Assets.

11.03 Tenant shall also provide, at Tenant’s sole cost and expense (i) insurance

13

protecting Landlord and Managing Agent against any and all lost Rents and Additional Rents under this Lease (fixed, additional or otherwise) for a period of one (1) year as a result of any injury or damage to the Demised Premises or the Building, and (ii) insurance covering all plate glass in the Demised Premises.

11.04 (A) All insurance required under this Article 11 shall name as an insured thereunder and as loss payee, Landlord (and, if requested by Landlord, Landlord’s mortqagee) and Landlord’s Managing Agent, and shall be in form reasonably satisfactory to Landlord, shall contain agreements by the insurer, without disclaimers and with waiver of subrogation, that the policy shall not be subject to cancellation, termination or change except after at least 30 days’ prior written notice to Landlord, Landlord’s Managing Agent, and Landlord’s mortgagee, shall be issued by an insurance company or companies reasonably satisfactory to Landlord, qualified to do business in the State of New York, and shall provide that the act or omission of one insured shall not invalidate the policy as to any other insured. All policies required pursuant to this Article 11, or duly executed certificates for the same, shall be deposited with Landlord and Managing Agent not less than 10 days prior to the commencement of the Term and any Option Term and upon renewals of said policies not less than 30 days prior to the expiration of the term of such coverage. All such policies or certificates shall be delivered together with satisfactory evidence of the payment of the premium therefor when such payment is due.

(B) There shall be maintained deductibles in such amounts as Tenant shall reasonably determine but in no event in excess of $5,000 with respect to property insurance and $10,000 with respect to liability insurance.

(C) All dividend and return premiums on each policy furnished by the Tenant shall belong to Tenant. If at any time Tenant shall neglect to effect the insurance required hereby, the Landlord may procure such insurance as the agent of the Tenant, and the amount of the premiums paid for such insurance by Landlord shall become immediately due from the Tenant as Additional Rent.

(D) Only Landlord and/or Landlord’s mortgagee shall be authorized to settle any claims resulting from destruction or damage to Tenant’s Assets or the Demised Premises, but Landlord shall consult with Tenant in connection therewith. The foregoing notwithstanding, Tenant shall be permitted to negotiate adjustment of insurance claims regarding medical equipment provided that any shortfall between the amount of the recovery and the actual cost to replace such equipment shall be paid for by Tenant.

11.05 Landlord shall insure the Building against damage or destruction by fire or other casualties under a policy of insurance, including broad form, extended coverage “all risk” endorsements. Said insurance shall be in an amount equal to not less than one hundred (100%) percent of the full insurable replacement value of the Building and may contain a deductible in such amount, as Landlord determines after consultation with Tenant, provided, however, (a) in the event the Demised Premises shall be damaged by fire or other cause, Tenant shall be responsible for, and shall pay to Landlord, as Additional Rent, the amount of the deductible and (b) if Tenant shall notify Landlord that it objects to the amount of the deductible, then Landlord shall cause the insurance to be amended to eliminate the deductible. From time to time, Landlord may, in its sole discretion increase or add to the amounts and types of coverage consistent with community standards.

ARTICLE 12

Subordination, Attornment, Notice to Lessor and Mortgagees

12.01 This Lease, and all rights of Tenant hereunder, are and shall be (a) subject and subordinate in all respects to all present and future ground leases, over-riding leases and underlying leases and/or grants of term of the Real Property and/or the Building in which the

14

Demised Premises shall be located( “superior leases”) (b) subject and subordinate to all mortgages and building loan agreements, which may now or hereafter affect the land and/or the Building and/or any superior leases, (c) at the option of the holder of the first mortgage on the Building, subordinate to the first mortgage thereon, and (d) if consented to by such holder of the first mortgage, at the option of the holder of any junior or secondary mortgages, subordinate to such junior or secondary mortgages (any of which mortgages referred to in clauses (b), (c) and (d) hereof, whether or not subordinate, are herein referred to as “superior mortgages”), whether or not the superior leases or superior mortgages shall also cover other lands and/or buildings, and the foregoing shall extend to each and every advance made or hereafter to be made under the superior mortgages, and to all renewals, modifications, replacements and extensions of the superior leases and superior mortgages and spreaders, consolidations and modifications of the superior mortgages. This Section shall be self-operative (after the holder of any superior mortgages exercises its option or grants its consent, as above provided) and no further instrument of subordination shall be required. In confirmation of such subordination, Tenant shall within 10 days after receipt thereof execute and deliver at its own cost and expense any instrument, in recordable form, if required, that Landlord, the lessor of any superior lease or the holder of any superior mortgage or any of their respective successors or prospective successors in interest may request to evidence such subordination. If Tenant fails to execute any such instrument within said 10-day period, (a) such failure shall, at Landlord’s sole election, constitute a material default by Tenant under this Lease and, in such event, Tenant agrees to pay as liquidated damages, in addition to all other remedies available to Landlord, an amount equal to $100 per day for each day that Tenant fails to deliver such certificate to Landlord after the expiration of such 10-day period and (b) Tenant irrevocably appoints Landlord as its attorney-in-fact, in Tenant’s name, to execute such instrument.

Tenant agrees without further instruments of attornment in each case, to attorn to lessor under any superior lease, or to the holder of any superior mortgage or any successor to such holder’s interest, upon such holder’s or successor’s request, as the case may be, to waive the provisions of any statute or rule or lav; now or hereafter in effect which may give or propose to give Tenant any right of election to terminate this Lease or to surrender possession of the Demised Premises in the event a superior lease is terminated or a superior mortgage is foreclosed, and that unless and until said lessor, or holder, as the case may be, shall elect to terminate this Lease, Tenant’s obligations under this Lease shall not be affected in any way whatsoever by any such proceeding or termination (it being understood, however, that such holder or successor in interest shall under no circumstances be bound by any payment of rent for more than one month in advance, except for the Security Deposit, if any, or be bound by any amendment or modification of the Lease without the consent of such holder or successor in interest), and Tenant shall take no steps to terminate this Lease without giving written notice to said lessor under the superior lease, or holder of a superior mortgage, and a reasonable opportunity to cure (without such lessor or holder being obligated to cure), any default on the part of the Landlord under this Lease. In confirmation of such attornment, Tenant shall within 10 days execute and deliver at its own cost and expense any instrument, in recordable form, if required, that Landlord, the lessor of any superior lease or the holder of any superior mortgage or any of their respective successors in interest may request to evidence such attornment. If Tenant fails to execute any such instrument within said 10-day period, (a) such failure shall constitute a material default by Tenant under this Lease and, in such event, Tenant agrees to pay as liquidated damages, in addition to all other remedies available to Landlord, an amount equal to $100 per day for each day that Tenant fails to deliver such certificate to Landlord after the expiration of such 10-day period and (b) Tenant irrevocably appoints Landlord as its attorney-in-fact, in Tenant’s name, to execute such instrument.

ARTICLE 13

Assignment, Mortgaging, Subletting

13.01 Neither this Lease nor the Term or Option Term and estate hereby granted, nor any part hereof or thereof, nor the interest of Tenant in any sublease or the rentals thereunder, shall be assigned, mortgaged, pledged, encumbered or otherwise transferred by Tenant by operation of law or otherwise, and neither the Demised Premises nor any part thereof, shall be encumbered in any manner by reason of any act or omission on the part of Tenant or anyone claiming under or through Tenant, or shall be sublet or be used or occupied or permitted to be used or occupied by anyone other than Tenant or for any purpose other than as permitted by this Lease, except as expressly otherwise provided in this Article. Subject to the consent of Landlord’s mortgagee, and except as hereafter specified, Tenant may sublet and/or assign all, but not less than all of the Demised Premises with the express prior written consent of Landlord, which consent shall not be unreasonably withheld. The foregoing notwithstanding, Tenant shall not sublet the Demised Premises to any current tenant of the Building or any prospective tenant which shall have dealt with Landlord, directly or indirectly, within six (6) months preceding such sublease. If Tenant shall sublease the Demised Premises and pursuant to such sublease. Tenant shall be entitled to receive rental or any other form of compensation for the use and occupancy or operation of the Demised Premises which is in excess of the Rent and Additional Rent to be paid by Tenant to Landlord under this Lease, Tenant shall remit to Landlord 50% of such excess on the first day of each month during the duration of such sublease. Any failure of Tenant to remit such sum when due shall constitute a default by Tenant in the payment of rental hereunder.

13.02 If this Lease be assigned, whether or not in violation of the provisions of this Lease, Landlord may collect rent from the assignee. If the Demised Premises or any part thereof be sublet or be used or occupied by anybody other than Tenant, whether or not in violation of this Lease, Landlord may after default by Tenant, and expiration of Tenant’s time to cure such default, collect rent from the subtenant or occupant. In either event, Landlord may apply the net amount collected to the rents herein reserved, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of any of the provisions of Section 13.01, or the acceptance of the assignee, subtenant or occupant as Tenant, or a release of Tenant from the further performance by Tenant of Tenant’s obligations under this Lease. The consent by Landlord to assignment, mortgaging, subletting or use or occupancy by others shall not in any way be considered to relieve Tenant from obtaining the express written consent of Landlord to any other or further assignment, mortgaging, or subletting or use or occupancy by others not expressly permitted by this Article. Tenant agrees to pay to Landlord reasonable counsel fees incurred by Landlord in connection with any proposed assignment of Tenant’s interest in this Lease or any proposed subletting of the Demised Premises or any part thereof (including, without limitation, the preparation and/or review of any and all documents in connection with any rights under this Article 13) whether or not such transaction is concluded.

The parties hereto acknowledge that the Landlord has a unique interest in the identity and nature of any occupant in the Building, and, therefor, notwithstanding any law or rule of law to the contrary, Landlord may withhold its consent to any particular subtenant (other than those named above) as well as any sublease of the entire Demised Premises, in its sole and absolute discretion, subject only to those laws relating to unlawful discrimination. Without limiting the generality of the foregoing, and except for the corporations named above, so long as the Mt. Kisco Medical Group P.C, (“MKMG”) or its successors or assigns shall conduct a medical practice having more than twenty physicians in the Town and Village of Mt, Kisco, the Demised Premises shall not be used by: a medical management services or similar organization which provides management or administrative services to physician practices (“MSO”); a physician practice management company which

The provisions of this Section to the contrary notwithstanding, the Demised Premises or any part thereof may be leased to the extent otherwise permitted herein to any of the following: any affiliate of MKMG, any medical specialty not competitive as of August 27, 1998 with MKMG, psychiatry practices, employee assistance programs, rehabilitative medicine practices, chiropractic practices, oral surgery practices, dental practices, occupational health programs, neurosurgical practices or physiatry practices.

13.04 This Lease may be assigned or sublet to a corporation, partnership or limited liability company which is controlled and 100% owned by Tenant or under common control through representatives having not less than the full right and power to make all decisions without restriction (sometimes the foregoing is in this Lease called “affiliate”), or the Demised Premises may be sublet to a subtenant approved by Landlord in writing pursuant to this Article or named in this Article 13 so long as the Demised Premises continue to be used for the permitted use; the transfer is not principally for the purpose of transferring the leasehold estate created hereby; Tenant shall remain liable to Landlord to the full extent of this Lease; the assignee or sublessee assumes by documents satisfactory to Landlord all of Tenant’s obligations to be performed under this Lease with respect to the space assigned or sublet; and subject to all of the other terms and conditions of this Lease, provided that Tenant notifies Landlord thereof within 20 days prior to the occurrence of any such event.

13.05 If any suit be brought by anyone other than Tenant alleging that the plaintiff therein was injured by virtue of Landlord’s failure or refusal to grant its consent under this Article 13, Tenant shall indemnify and hold Landlord harmless from and against any and all loss, cost, damage or expense (including all legal fees and costs) arising from such suit.

ARTICLE 14

In such event, Landlord shall, subject to compliance with the provisions of any superior mortgage or superior lease, and to its rights under Section 17.03, repair the damage and restore and rebuild the Demised Premises with reasonable diligence as nearly as may be practicable to its condition immediately prior to such damage. If the proceeds of Tenant’s insurance coverage are in the opinion of Landlord insufficient to restore and rebuild the Demised Premises, Landlord’s obligation to repair the damage and restore and rebuild the Demised Premises shall be subject to Tenant’s payment to Landlord of such insufficiency prior to commencement of any work.

17.02 If the Demised Premises shall be partially or totally damaged or rendered partially or totally untenantable by fire or other cause without the fault or neglect of Tenant, Tenant’s employees, agents, contractors, visitors or licensees, until such repairs are made the Rent shall

19

be apportioned according to the part of the Demised Premises which is usable by Tenant and shall be abated from the date of such damage to the date rent loss insurance shall be exhausted. However, if the proceeds of Tenant’s insurance coverage are in the opinion of Landlord insufficient to restore and rebuild the Demised Premises, Landlord’s obligation to repair the damage and restore and rebuild the Demised Premises shall be subject to Tenant’s payment to Landlord of such insufficiency prior to commencement of any work.

17.03 If the Demised Premises are totally or substantially damaged or are rendered wholly or substantially untenantable by fire or other cause, and if Landlord shall decide not to restore or not to rebuild the same, or if the Building shall be so damaged that Landlord shall decide to demolish it or not to rebuild it (whether or not the Demised Premises have been damaged), then in any of such events Landlord may, within one hundred twenty (120) days after the occurrence of such casualty, give Tenant notice of such decision, and thereupon the Term of this Lease shall expire upon the date set forth in such notice as fully and completely as if such date were the Expiration Date of this Lease. Tenant shall then forthwith quit, surrender and vacate the Demised Premises. Such termination and surrender shall be without prejudice to Landlord’s rights and remedies against Tenant under the Lease provisions in effect prior to such termination, and the Rent reserved hereunder shall be apportioned as of such date if not earlier abated pursuant to Section 17.02.

17.04 Unless Landlord shall serve a termination notice as provided for in Section 17.03 hereof, Landlord shall make the repairs and restorations as above-described, with all reasonable expedition subject to delays due to adjustment of insurance claims and Events of Force Majeure. No damages, compensation or claims shall be payable by Landlord for delay, inconvenience, loss of business or annoyance arising from any repair or restoration of any portion of the Demised Premises or of the Building.

17.05 For purposes of this Article 17, casualty damage which Landlord is responsible to repair shall not be deemed to include damage caused by vandalism, unknown cause or other act not normally covered under fire and extended coverage insurance policies applicable to office buildings in the area in which the Building is located.

17.06 The provisions of this Article shall be considered an express agreement governing any case of damage or destruction of the Demised Premises by fire or other casualty, and any laws now or hereinafter in force providing for such a contingency in the absence of an express agreement shall have no application in such case.

17.07 Notwithstanding any of the foregoing provisions of this Article, if Landlord or the lessor of any superior lease or the holder of any superior mortgage shall be unable to collect all of the insurance proceeds applicable to damage or destruction of the Demised Premises or the Building by reason of some action or inaction on the part of Tenant or any of its employees, agents or contractors, then, without prejudice to any other remedies which may be available against Tenant, the abatement of Tenant’s rent provided for in this Article shall not be effective to the extent of the uncollected insurance proceeds.

20

ARTICLE 18

Eminent Domain; Condemnation

18.01 In the event that the Real Property, Building, or any part of the Demised Premises, shall be taken in condemnation proceedings or by the exercise of any right of eminent domain or by agreement between any superior lessors and lessees and/or Landlord on the one hand and any governmental authority authorized to exercise such right on the other hand, Landlord shall be entitled to collect from any condemnor the entire award or awards that may be made in any such proceeding without deduction therefrom for any estate hereby vested in or owned by Tenant, to be paid out as in this Article provided. Tenant hereby expressly assigns to Landlord all of its right, title and interest in or to every such award and also agrees to execute any and all further documents that may be required in order to facilitate the collection thereof by Landlord.

18.02 At any time during the Term if title to the whole or a substantial portion of the Real Property, the Building or Demised Premises shall be taken in condemnation proceedings or by the exercise of any right of eminent domain or by agreement between any superior lessors and lessees and/or Landlord on the one hand and any governmental authority authorized to exercise such right on the other hand, at Landlord’s option, this Lease shall terminate and expire on the date of such taking and the Base Rent and Additional Rent provided to be paid by Tenant shall be apportioned and paid to the date of such taking.

18.03 Either party may elect to terminate this Lease if the Demised Premises shall be reduced by more than 20% by notice of such election to the other party given not later than thirty {30} days after (i) notice of such taking is given by the condemning authority, or (ii) the date of such taking, whichever occurs later. Upon the giving of such notice this Lease shall terminate on the date of service of such notice and the Base Rent and Additional Rent due and to become due, shall be prorated and adjusted as of the date of the taking. If both parties fail to give such notice upon such partial taking, and this Lease continues in force as to any part of the Demised Premises not taken, the rents apportioned to the part taken shall be prorated and adjusted as of the date of taking and from such date the Base Rent and Additional Rent shall be reduced to the amount apportioned to the remainder of the Demised Premises.

18.04 Notwithstanding the foregoing provisions of this Article and subject to the interests of any mortgagee or lessor or grantor under any superior mortgage or superior lease, Tenant shall be entitled to appear, claim, prove and receive in the proceedings relating to any taking mentioned in the preceding Sections of this Article, such portion of each award made therein as represents any moving or relocation expenses to which Tenant may be entitled, and any special awards or allowances provided by law to Tenants whose space has been taken by eminent domain, so long as the foregoing does not reduce Landlord’s award and does not include the value of the leasehold estate which shall belong to Landlord.

18.05 In the event of any such taking of all or any part of the Demised Premises which does not result in a termination of this Lease, subject to compliance with the provisions of any superior mortgage and superior lease, Tenant (or Landlord as and to the extent provided in Article 17 hereof as if damage and destruction covered thereby were involved) shall proceed with reasonable diligence to repair, alter and restore the remaining part of the Demised Premises to substantially the same condition as it was in immediately prior to the date of such taking to the extent that the same may be feasible, so as to. constitute a Tenantable Demised Premises.

21

ARTICLE 19

Surrender

19.01 On the last day of the Term, or the Option Term if in effect, or upon any earlier termination of this Lease, or upon any re-entry by Landlord upon the Demised Premises, Tenant shall quit and surrender the Demised Premises to Landlord broom clean, in good order, condition and repair except for ordinary wear and tear and damage by fire or other insured casualty, restored as provided in Section 8.01, if applicable.

19.02 Prior to such surrender, Tenant shall (a) remove any Tenant’s property not part of the personal property as otherwise provided herein, including, without being limited to, all of Tenant’s machinery, equipment, medical equipment and machines bolted to the floor and such fixtures as Landlord shall designate, whether or not previously deemed to be the property of Landlord, (b) at Landlord’s request, repair any damage and make any replacements to the Building or the Demised Premises resulting from or necessitated by such removal, and restore those parts of the Demised Premises from which the removal referred to in subparagraph (a) above occurred, to a condition which will be suitable for non-specialized medical office use, and (c) Tenant shall restore the Demised Premises including, without limitation, any floor space area which may have been removed in order to accommodate Tenant’s needs, the Demised Premises to be restored to that state or condition as shall be useable for non-specialized, medical office use. If Tenant shall fail to perform as provided in this Section 19.02 hereof, Landlord shall have the right (but not the obligation) to do so at Tenant’s cost and expense, without further notice or demand upon Tenant, and Tenant shall indemnify Landlord against all loss or liability resulting therefrom, including without limitation, any delay in granting occupancy of the Demised Premises to a future occupant, and, at Landlord’s option, Tenant shall be deemed a Tenant “at will” until compliance with the removal, repair and restoration provisions of this Section 19.02 hereof has fully been satisfied.

19.03 Tenant hereby indemnifies and agrees to hold Landlord harmless from and against any loss, cost, liability, claim, damage, fine, penalty and expense, including reasonable attorneys’ fees and disbursements, resulting from delay by Tenant in surrendering the Demised Premises upon the termination of this Lease as provided in this Article 19, including without limitation, any claims made by any succeeding Tenant or prospective Tenant-based upon such delay.

19.04 In the event Tenant remains in possession of the Demised Premises for a period of more than sixty (60) days after the termination of this Lease without the execution by Landlord and Tenant of a new Lease, Tenant, at the option of Landlord, shall be deemed to be occupying the Demised Premises as a Tenant “at will”, at a monthly rental equal to two times the Base Rent and Additional Rent payable during the last month of the Term or any Option Term, subject to all of the other terms of this Lease insofar as the same are applicable to an at will tenancy, and without in any way whatsoever waiving the provisions of Section 19.03 hereof. In the event of any holdover of less than sixty (60) days, Tenant shall pay Landlord Rent and Additional Rent at the rate in effect during the last month of the Term or any Option Term.

ARTICLE 20

Conditions of Limitation

20.01 This Lease and the Term and estate hereby granted are subject inter alia to the limitation that whenever Tenant shall make an assignment for the benefit of creditors, or shall file a voluntary petition under any bankruptcy or insolvency law, or an involuntary petition alleging an act of bankruptcy or insolvency is filed against Tenant, or whenever a petition shall be filed by or against Tenant seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or any future federal

22

bankruptcy act or other present or future applicable federal, state or other statute or lav;, or shall seek or consent to or acquiesce in the appointment of any trustee, receiver or liquidator of Tenant or of all or any substantial part of its properties, or whenever a permanent or temporary receiver of Tenant or of, or for, the property of Tenant shall be appointed, or if Tenant shall plead bankruptcy or insolvency as a defense in any action or proceeding, then, Landlord, (a) at any time after receipt of notice of the occurrence of any such event, or (b) if such event occurs without the acquiescence of Tenant, at any time after the event continues for 45 days, may give Tenant a notice of intention to end the Term at the expiration of five (5) days from the service of such notice of intention, and upon the expiration of said five (5) day period this Lease and the Term and estate hereby granted, whether or not the Term shall theretofore have commenced, shall terminate with the same effect as if that day were the Expiration Date, but Tenant shall remain liable for damages as provided as in Article 22.

20.02 This Lease and the Term and estate hereby granted are subject to the further limitation that, (a) whenever Tenant shall default in the payment of any installment of Base Rent, or in the payment of any Additional Rent, on any day upon which the same shall be due and payable, or (b) whenever Tenant shall do or permit anything to be done, whether by action or inaction, contrary to any of Tenant’s obligations hereunder, other than the payment of rent, and if such situation shall continue and shall not be remedied by Tenant within fifteen (15) days after Landlord shall have given to Tenant a notice specifying the same, or, in the case of a happening or default which cannot with due diligence be cured within a period of fifteen (15) days and the continuance of which for the period required for cure will not subject Landlord to the risk of criminal liability or termination of any superior lease or foreclosure of any superior mortgage, if Tenant shall not duly institute within such fifteen (15) day period and promptly and diligently prosecute to completion all steps necessary to remedy the same, or, (c) whenever any event shall occur or any contingency shall arise whereby this Lease or any interest therein or the estate hereby granted or any portion thereof or the unexpired balance of the Term hereof would, by operation of law or otherwise, devolve upon or pass to any person, firm or corporation other than Tenant, except as expressly permitted by Article 13, or (d) whenever Tenant shall abandon the Demised Premises, or a substantial portion of the Demised Premises shall remain vacant for a period of ten (10) consecutive days unless such vacancy arises as a result of a casualty; then in any such event covered by subsections a, b, c or d of this Section 20.02 at any time thereafter, Landlord may give to Tenant a notice of intention to end the Term of this Lease at the expiration of three (3) days from the date of the service of such notice of intention, and upon the expiration of said three (3) days this Lease and the Term and estate hereby granted, whether or not the Term shall theretofore have commenced, shall terminate with the same effect as if that day were the Expiration Date, but Tenant shall remain liable for damages as provided in Article 22.

23

ARTICLE 21

Re-Entry by Landlord — Default Provisions

21.01 If this Lease shall terminate for any reason whatsoever, Landlord or Landlord’s agents and employees may, without further notice, immediately or at any time thereafter, enter upon and re-enter the Demised Premises, or any part thereof, and possess or repossess itself thereof either by summary dispossess proceedings, ejectment or by any suitable action or proceeding at law, or by agreement, or otherwise, and may dispossess and remove Tenant and all other persons and property from the Demised Premises without being liable to indictment, prosecution or damages therefor, and may repossess the same, and may remove any persons therefrom, to the end that Landlord may have, hold and enjoy the Demised Premises and the right to receive all rental income again as and of its first estate and interest therein. In the event of any termination of this Lease under the provisions of Article 20 or re-entry under this Article by reason of default hereunder on the part of Tenant, Tenant shall thereupon pay to Landlord the Base Rent and Additional Rent due up to the time of such termination of this Lease or of such recovery of possession of the Demised Premises by Landlord, as the case may be, and shall also pay to Landlord damages as provided in Article 22.

21.02 In the event of any breach or threatened breach by Tenant of any of the agreements, terms, covenants or conditions contained in this Lease, Landlord shall be entitled to enjoin such breach or threatened breach and shall have the right to invoke any right and remedy allowed at law or in equity or by statute or otherwise as though re-entry, summary proceedings, and other remedies were not provided for in this Lease.

21.03 Each right and remedy of Landlord provided for in this Lease shall be cumulative and shall be in addition to every other right or remedy provided for in this Lease or now or hereafter existing at law or in equity or by statute or otherwise, and the exercise or beginning of the exercise by Landlord of any one or more of the rights or remedies provided for in this Lease or now or hereafter existing at law or in equity or by statute or otherwise shall not preclude the simultaneous or later exercise by Landlord of any or all other rights or remedies provided for in this Lease or now or hereafter existing at law or in equity or by statute or otherwise.

ARTICLE 22

Damages

22.01 If this Lease is terminated under the provisions of Article 20, or if Landlord shall re-enter the Demised Premises under the provisions of Article 21 or in the event of the termination of this Lease, or of re-entry by reason of default hereunder on the part of Tenant, Tenant shall pay to Landlord as damages, at the election of Landlord, either,

(a) on demand, a sum which at the time of such termination of this Lease or at the time of any such re-entry by Landlord, as the case may be, represents the excess of (1) the aggregate of the Base Rent and the Additional Rent payable hereunder which would have been payable by Tenant (conclusively presuming the Additional Rent to be the same as was payable for the year immediately preceding such termination) for the period commencing with such earlier termination of this Lease or the date of any such re-entry, as the case may be, and ending with the expiration of the Term, had this Lease not so terminated or had Landlord not so re-entered the Demised Premises, over (2) the aggregate rental value (calculated as of the date of such termination or re-entry) of the Demised Premises for the same period, or,

(b) sums equal to the Base Rent and the Additional Rent (as above presumed) payable hereunder which would have been payable by Tenant had this Lease not so terminated,

24

or had Landlord not so re-entered the Demised Premises, payable quarterly but otherwise upon the terms therefor specified herein following such termination or such re-entry and until the expiration of the Term, provided, however, that if Landlord shall relet the Demised Premises or any portion or portions thereof during said period, Landlord shall credit Tenant with the net rents received by Landlord from such reletting, such net rents to be determined by first deducting from the gross rents as and when received by Landlord from such reletting the expenses incurred or paid by Landlord in terminating this Lease or in re-entering the Demised Premises and in securing possession thereof, as well as the expenses of reletting, including altering and preparing the Demised Premises or any portion or portions thereof for new Tenants, brokers commissions, advertising expenses, attorneys, fees’ and all other expenses properly chargeable against the Demised Premises and the rental therefrom; it being understood that any such reletting may be for a period shorter or longer than the remaining Term of this Lease, but in no event shall Tenant be entitled to receive any excess of such net rents over the sums payable by Tenant to Landlord hereunder, nor shall Tenant be entitled in any suit for the collection of damages pursuant to this Subsection to a credit in respect of any net rents from a reletting, except to the extent that such net rents are actually received by Landlord. If the Demised Premises or any part thereof should be relet in combination with other space, then proper apportionment shall be made of the rent received from such reletting and of the expenses of reletting.

If the Demised Premises or any part thereof be relet by Landlord for the unexpired portion of the Term, or any part thereof, before presentation of proof of such damages to any court, commission, or tribunal, the amount of rent reserved upon such reletting shall, prima facie, be the fair and reasonable rental value for the Demised Premises, or part thereof, so relet during the term of the reletting. Landlord however shall in no event and in no way be responsible or liable for any failure to relet the Demised Premises or any part thereof or for failure to collect any rent due upon any such reletting.

22.02 Suit or suits for the recovery of such damages, or any installments thereof, may be brought by Landlord from time to time at its election, and nothing contained herein shall be deemed to require Landlord to postpone suit until the date when the Term would have expired if it had not been so terminated under the provisions of Article 20, or under any provision of law, or had, Landlord not re-entered the Demised Premises. Nothing herein contained shall be construed to limit or preclude recovery by Landlord against Tenant of any sums or damages to which, in addition to the damages particularly provided above, Landlord may lawfully be entitled by reason of any default hereunder or otherwise on the part of Tenant. Nothing herein contained shall be construed to limit or prejudice the right of the Landlord to prove for and obtain as liquidated damages by reason of the termination of this Lease or re-entry on the Demised Premises for the default of Tenant under this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, such damages are to be proved whether or not such amount be greater, equal to, or less than any of the sums referred to in Section 22.01.

22.03 Anything in this Lease to the contrary notwithstanding, if Tenant shall at any time be in default hereunder, and if Landlord shall institute an action or summary proceeding against Tenant based upon such default, or if such default results from non-payment of Base Rent or Additional Rent whether or not such an action or proceeding is instituted, or if Tenant requests Landlord to review or execute documents (including, without limitation, any sublease or occupancy documents) in connection with this Lease, or otherwise if it is reasonably prudent for Landlord to contact counsel, then Tenant shall reimburse Landlord, as Additional Rent, for the expense of attorneys’ fees and disbursements thereby incurred by Landlord.

ARTICLE 23

Waivers

23.01 Tenant, for itself, and on behalf of any and all persons claiming through or under

25

Tenant, including creditors of all kinds, does hereby waive and surrender all right and privilege so far as is permitted by law, which they or any of them might have under or by reason of any present or future law, of the service of any notice of intention to re-enter and also waives any and all right of redemption or re-entry or repossession in case Tenant shall be dispossessed or ejected by process of law or in case of re-entry or repossession by Landlord or in case of any expiration or termination of this Lease as herein provided.

23.02 Tenant waives Tenant’s rights, if any, to designate the items against which any payments made by Tenant are to be credited, and Tenant agrees that Landlord may apply any payments made by Tenant to any items it sees fit, irrespective of and notwithstanding any designation or request by Tenant as to the items against which any such payments shall be credited.

23.03 Except to the extent that a mandatory counterclaim is involved, Tenant waives Tenant’s rights, if any, to assert a counterclaim in any summary proceeding brought by Landlord against Tenant for non-payment of rent or Additional Rent, and Tenant agrees to assert any such claim against Landlord only by way of a separate action or proceeding.

23.04 To the extent permitted by applicable law, Landlord and Tenant hereby waive trial by jury in any action, proceeding or counterclaim brought by either against the other on any matter whatsoever arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant, or Tenant’s use or occupancy of the Demised Premises, or any emergency or other statutory remedy with respect thereto.

ARTICLE 24

No Other Waivers or Modifications

24.01 The failure of either party to insist in any one or more instances upon the strict performance of any one or more of the agreements, terms, covenants, conditions or obligations of this Lease, or to exercise any right, remedy or election herein contained, shall not be construed as a waiver or relinquishment for the future of the performance of such one or more obligations of this Lease or of the right to exercise such election, but the same shall continue and remain in full force and effect with respect to any subsequent breach, act or omission. No executory agreement hereafter made between Landlord and Tenant shall be effective to change, modify, waive, release, discharge, terminate or effect an abandonment of this Lease, in whole or in part, unless such executory agreement is in writing, refers expressly to this Lease and is signed by the party against whom enforcement of the change, modification, waiver, release, discharge or termination or effectuation of the abandonment is sought.

24.02 The following specific provisions of this Section shall not be deemed to limit the generality of the foregoing provisions of this Article:

(a) No agreement to accept a surrender of all or any part of the Demised Premises shall be valid unless in writing and signed by Landlord. The delivery of keys to an employee of Landlord or of its agent shall not operate as a termination of this Lease or a surrender of the Demised Premises. If Tenant shall at any time request Landlord to sublet the Demised Premises for Tenant’s account, Landlord or its agent is authorized to receive said keys for such purposes without releasing Tenant from any of its obligations under this Lease, and Tenant hereby releases Landlord of any liability for loss or damage to any of Tenant’s Property in connection with such subletting.

(b) The receipt or acceptance by Landlord of rents with knowledge of breach by Tenant of any term, agreement, covenant, condition or obligation of this Lease shall not be deemed a waiver of such breach.

(c) No payment by Tenant or receipt by Landlord of a lesser amount than the correct

26

Base Rent or Additional Rent due hereunder shall be deemed to be other than a payment on account, nor shall any endorsement or statement on any check or any letter accompanying any check or payment be deemed to effect or evidence an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance or pursue any other remedy in this Lease or at law provided.

(d) If, in connection with obtaining, continuing or renewing financing for which the Building, land or a leasehold or any interest therein represents collateral in whole or in part, a banking, insurance or other lender shall request modifications of this Lease as a condition of such financing, Tenant will not unreasonably withhold, delay or defer its consent thereto, provided that such modifications do not increase the obligations of Tenant hereunder or adversely affect to a material degree the Tenant’s leasehold interest hereby created; among other items, any change in the Term or increase in the Base Rent shall be deemed material.

ARTICLE 25

Curing Tenant’s Defaults

25.01 If Tenant shall default in the performance of any covenant, agreement, term, provision or condition herein contained, Landlord without thereby waiving such default, may perform the same for the account and at the expense of Tenant without notice in case of emergency and in any other case if such default continues after three days from the due date of the giving by Landlord to Tenant of written notice of intention so to do. Bills for any reasonable and necessary expense incurred by Landlord in connection with any such performance by Landlord for the account of Tenant, and reasonable and necessary bills for all costs, expenses and disbursements, including (without being limited to) reasonable counsel fees, incurred in collecting or endeavoring to collect the Base Rent or Additional Rent or other charge or any part thereof or enforcing or endeavoring to enforce any rights against Tenant under or in connection with this Lease, or pursuant to law, shall be payable by Tenant within three (3) days of notice to Tenant and if not paid when due, the amounts thereof shall immediately become due and payable as Additional Rent under this Lease together with interest thereon at the lesser of the maximum rate permitted by law or the rate of three percent (3 %) per month or portion thereof from the date the said bills should have been paid in accordance with their terms.

ARTICLE 26

Parties Bound

29.01 The obligations of this Lease shall bind and benefit the successors and assigns of the parties with the same effect as if mentioned in each instance where a party is named or referred to, except that no violation of the provisions of Article 13 shall operate to vest any rights in any successor or assignee of Tenant, and that the provisions of this Article shall not be construed as modifying the conditions of limitation contained in Article 20, However, the obligations of Landlord under this Lease shall not be binding upon Landlord herein named with respect to any period subseguent to the transfer of its interest in the Building as owner or lessee thereof and in the event of such transfer said obligations shall thereafter be binding upon each transferee of the interest of Landlord herein named as such owner or lessee of the Building, but only with respect to obligations arising during the period commencing with such transfer and ending with a subsequent transfer within the meaning of this Article, and such transferee, by accepting such interest, shall be deemed to have assumed such obligations except only as may be expressly otherwise provided elsewhere in this Lease.
