The provisions of this paragraph shall not apply to Permitted Transfers. ARTICLE VII INDEMNITY AND INSURANCE Section 7.1 - INDEMNITY.

Landlord agrees to defend, indemnify and save harmless Tenant from legal action, damages, loss, liability and any other expense in connection with loss of life, bodily or personal injury or property damage, arising from or out of the intentional or willful misconduct or gross negligence of Landlord, its agents, employees, licensees, servants, invitees or contractors, which occur in or about the Premises, outside the Premises but within the Building, on the Land, on the access roads and ways, in the parking facilities provided pursuant to the Lease, within University Park or any adjacent area maintained by Landlord, except to the extent that such loss of life, bodily or personal injury or property damage is due to the willful misconduct or act, omission or neglect of Tenant, its agents, contractors, employees, licensees, invitees or servants. The foregoing indemnities and hold harmless agreements shall include indemnity against reasonable attorneys' fees and all other costs, expenses and liabilities incurred in connection with any such claim or proceeding brought thereon, and the defense thereof. Section 7.2 - LIABILITY INSURANCE. The Tenant agrees to maintain in full force from the date upon which the Tenant first enters the Premises for any reason, throughout the Term, and thereafter, so long as the Tenant is in occupancy of any part of the Premises, a policy of comprehensive general liability insurance written by a company having an Alfred M. Best Co. rating of A or better, and a financial size rating of XII or higher, under which the Landlord (and any individuals or entities affiliated with the Landlord and University Park, any ground lessor and any holder of a mortgage on the Property of whom the Tenant is notified by the Landlord, collectively with the Landlord, the "Named Insureds") and the tenant, as their interests appear under this Lease are named as insureds, and under which the insurer provides a contractual liability endorsement insuring against all cost, expense and liability arising out of or based upon any and all claims, accidents, injuries and damages described in Section 7.1, in the broadest form of such 16 20 coverage from time to time available. Each such policy shall be noncancellable and non-amendable (to the extent that any proposed amendment reduces the limits or the scope of the insurance required in this Lease) with respect to the Landlord and such ground lessors and mortgagees without thirty (30) days prior notice to the Landlord and such ground lessors and mortgagees and a certificate evidencing Tenant's insurance required hereunder shall be delivered to the Landlord. The minimum limits of liability of such insurance as of the Commencement Date shall be Three Million Dollars ($3,000,000.00) for combined bodily injury (or death) and damage to property (per occurrence), and from time to time during the Term such limits of liability shall be reasonably increased to reflect such higher limits as are customarily required pursuant to new leases of space in the Boston-Cambridge area with respect to similar properties and similar uses. Section 7.3 - PERSONAL PROPERTY AT RISK. The Tenant agrees to maintain in full force at all times throughout the Term, policy(s) of all risk property damage insurance, naming Landlord (and the Additional Named Insureds) and the Tenant as insureds as their interests may appear, covering all of Tenant's leasehold improvements and alterations to the extent of their full replacement costs as updated from time to time during the Term. The Tenant agrees that all of the furnishings, fixtures, equipment, effects and property of every kind, nature and description of the Tenant and of all persons claiming by, through or under the Tenant which, during the continuance of this Lease or any occupancy of the Premises by the Tenant or anyone claiming under the Tenant, may be on the Premises or elsewhere in the Building or on the Lot or parking facilities provided hereby, shall be at the sole risk and hazard of the Tenant, and if the whole or any part thereof shall be destroyed or damaged by fire, water or otherwise, or by the leakage or bursting of water pipes, steam pipes, or other pipes, by theft or from any other cause, no part of said loss or damage is to be charged to or be borne by the Landlord, except that the Landlord shall in no event be exonerated from any liability to the Tenant or to any person, for any injury, loss, damage or liability to the extent such exoneration is prohibited by law. Section 7.4 - LANDLORD'S INSURANCE. 17 21 The Landlord shall carry such casualty and liability insurance upon and with respect to operations at the building, as may from time to time be deemed reasonably prudent by the Landlord or required by any mortgagee holding a mortgage thereon or any ground lessor of the Land, and in any event, insurance against loss by fire and the risks now covered by extended coverage endorsement No. 4 in an amount at least equal to the full replacement cost of the Building, exclusive of foundations, site preparation and other nonrecurring construction costs. Section 7.5 - WAIVER OF SUBROGATION. Any insurance carried by either party with respect to the Building, Land, Premises, parking facilities or any property therein or occurrences thereon shall without further request by either party, if it can be so written without additional premium, or with an additional premium which the other party elects to pay, include a clause or endorsement denying to the insurer rights of subrogation against the other party to the extent rights have been waived by the insured prior to occurrence of injury or loss. Each party, notwithstanding any provisions of this Lease to the contrary, hereby waives any rights of recovery against the other for injury or loss, including, without limitation, injury or loss caused by negligence of such other party, due to hazards covered by insurance actually carried or required to be carried hereunder. ARTICLE VIII CASUALTY AND EMINENT DOMAIN Section 8.1 - RESTORATION FOLLOWING CASUALTIES. If, during the Term, the Building or Premises shall be damaged by fire or casualty, subject to the exceptions and limitations provided below, the Landlord shall proceed promptly to exercise reasonable efforts to restore the Building or Premises to substantially the condition thereof at the time of such damage, but the Landlord shall not be responsible for delay in such restoration which may result from any cause beyond the reasonable control of the Landlord. The Landlord shall have no obligation to expend in the reconstruction of the Building more than the actual amount of the insurance proceeds made available to the Landlord by its insurer and not retained by the Landlord's mortgagee or ground lessor. Any restoration of the 18 22 Building or the Premises shall be altered to the extent necessary to comply with then current laws and applicable codes. Section 8.2 - LANDLORD'S TERMINATION ELECTION. If the Landlord reasonably determines that the amount of insurance proceeds available to the Landlord is insufficient to cover the cost of restoring the Building or if in the reasonable opinion of the Landlord the Building has been so damaged that it is appropriate for the Landlord to raze or substantially alter the Building, then the Landlord may terminate this Lease by giving notice to the Tenant within ninety (90) days after the date of the casualty or such later date as is required to allow the Landlord a reasonable time to make either such determination. Any such termination shall be effective on the date designated in such notice from the Landlord, but in any event, not later than ninety (90) days after such notice, and if no date is specified, effective upon the delivery of such notice. Section 8.3 - TENANT'S TERMINATION ELECTION. Unless the Landlord has earlier advised the Tenant of the Landlord's election to terminate this Lease pursuant to Section 8.2, or to restore the Premises and maintain this Lease in effect pursuant to Section 8.1, the Tenant shall have the right after the expiration of ninety (90) days after any casualty which materially impairs a material portion of the Premises to give a written notice to the Landlord requiring the Landlord within ten (10) days thereafter to exercise or waive any right of the Landlord to terminate this Lease pursuant to Section 8.2 as a result of such casualty and if the Landlord fails to give timely notice to the Tenant waiving any right under Section 8.2 to terminate this Lease based on such casualty, the Tenant shall be entitled, at any time until the Landlord has given notice to the Tenant waiving such termination right, to give notice to the Landlord terminating this Lease. Section 8.4 - CASUALTY AT EXPIRATION OF LEASE. If the Premises shall be damaged by fire or casualty in such a manner that the Premises cannot, in the ordinary course, reasonably be expected to be repaired within one hundred twenty (120) days from the commencement of repair work and such damage occurs within the last two (2) years of the Term (as the same may be extended), either party 19 23 shall have the right, by giving notice to the other not later than sixty (60) days after such damage, to terminate this Lease. This Lease shall terminate as of the date of any such notice given from Tenant to Landlord. This Lease shall terminate ten (10) days after the giving of any such notice from Landlord to Tenant, provided that Tenant has not validly exercised any then existing option to extend the Term hereof (as provided in Section 2.6 of this Lease) within such ten (10)-day period. Section 8.5 - EMINENT DOMAIN. Except as hereinafter provided, if the Premises, or such portion thereof as to tender the balance (if reconstructed to the maximum extent practicable in the circumstances) unsuitable for the Tenant's purposes, shall be taken by condemnation or right of eminent domain, the Landlord or the Tenant shall have the right to terminate this Lease by notice to the other of its desire to do so, provided that such notice is given not later than thirty (30) days after the effective date of such taking. If so much of the Building shall be so taken that the Landlord determines that it would be appropriate to raze or substantially alter the Building, the Landlord shall have the right to terminate this Lease by giving notice to the Tenant of the Landlord's desire to do so not later than thirty (30) days after the effective date of such taking. Should any part of the Premises be so taken or condemned during the Term, and should this Lease be not terminated in accordance with the foregoing provisions, the Landlord agrees to use reasonable efforts to put what may remain of the Premises into proper condition for use and occupation as nearly like the condition of the Premises prior to such taking as shall be practicable, subject, however, to applicable laws and codes then in existence and to the availability of sufficient proceeds from the eminent domain taking not retained by any mortgagee or ground lessor. Section 8.6 - RENT AFTER CASUALTY OR TAKING. If the Premises shall be damaged by fire or other casualty, except as provided below, the Annual Fixed Rent and Additional Rent shall be justly and equitably abated and reduced according to the nature and extent of the loss of use thereof suffered by the Tenant. If the fire or other casualty was caused by the Tenant, such abatement shall be made only to the extent that the Landlord is fully 20 24 compensated therefor by any lost rent insurance. In the event of a taking which reduces the area of the Premises, a just proportion of the Annual Fixed Rent shall be abated for the period of such taking. Section 8.7 - TAKING AWARD. Except as otherwise provided in Section 8.6, the Landlord shall have and hereby reserves and excepts, and the Tenant hereby grants and assigns to the Landlord, all rights to recover for damages to the Building and the Land, and the leasehold interest hereby created, and to compensation accrued or hereafter to accrue by reason of such taking, damage or destruction, as aforesaid, and by way of confirming the foregoing, the Tenant hereby grants and assigns to the Landlord, all rights to such damages or compensation. Nothing contained herein shall be construed to prevent the Tenant from prosecuting in any condemnation proceedings a claim for relocation expenses, provided that such action shall not affect the amount of compensation otherwise recoverable by the Landlord from the taking authority pursuant to the preceding sentence. ARTICLE IX DEFAULT Section 9.1 - TENANT'S DEFAULT. Each of the following shall constitute an Event of Default: (a) Failure on the part of the Tenant to pay the Annual Fixed Rent, Additional Rent or other charges for which provision is made herein on or before the date on which the same become due and payable, if such condition continues for ten (10) days after Landlord delivers to Tenant notification of such failure. Notwithstanding the foregoing, Landlord shall not be obligated to notify Tenant of its failure to pay Annual Fixed Rent, Additional Rent or other charges more than two (2) times during each Lease Year and if in any Lease Year after the Landlord has twice provided notice to the Tenant of such failures, the Tenant thereafter fails to make any payment referred in the preceding sentence on or before its due date, such failure shall constitute an Event of Default. (b) Failure on the part of the Tenant to perform or observe any other term or condition contained in this Lease if the Tenant shall not cure such failure within thirty (30) days after notice from the 21 25 Landlord to the Tenant thereof, provided that in the case of breaches of obligations under this Lease which are susceptible to cure but cannot be cured within thirty (30) days through the exercise of due diligence, so long as the Tenant commences such cure within thirty (30) days, such breach remains susceptible to cure, and the Tenant diligently pursues such cure, such breach shall not be deemed to create an Event of Default. (c) The taking of the estate hereby created on execution or by other process of law; or a judicial declaration that the Tenant is bankrupt or insolvent according to law; or any assignment of the property of the Tenant for the benefit of creditors; or the appointment of a receiver, guardian, conservator, trustee in bankruptcy or other similar officer to take charge of all or any substantial part of the Tenant's property by a court of competent jurisdiction; or the filing of an involuntary petition against the Tenant under any provisions of the bankruptcy act now or hereafter enacted if the same is not dismissed within ninety (90) days; the filing by the Tenant of any voluntary petition for relief under provisions of any bankruptcy law now or hereafter enacted. If an Event of Default shall exist, then, in any such case, whether or not the Term shall have begun, the Landlord lawfully may, immediately or at any time thereafter, give notice to the Tenant specifying the Event of Default and this Lease shall come to an end on the date specified therein as fully and completely as if such date were the date herein originally fixed for the expiration of the Lease Term, and the Tenant will then quit and surrender the Premises to the Landlord, but the Tenant shall remain liable as hereinafter provided. Section 9.2 - DAMAGES. In the event that this Lease is terminated by Landlord pursuant to the terms of Section 9.1 hereof, the Tenant covenants to pay to the Landlord forthwith on the Landlord's demand, as compensation, an amount (the "Lump Sum Payment") equal to the excess, if any, of the discounted present value of the total rent reserved for the remainder of the Term over the then discounted present fair rental value of the Premises for the remainder of the Term. In calculating the rent reserved, there shall be included, in addition to the Annual Fixed Rent and all Additional Rent, the value of all other considerations agreed to be paid or performed by the Tenant over the remainder of the Term. In addition, the Tenant shall pay punctually to the Landlord 22 26 all the sums ("Periodic Payments") and perform all the obligations which the Tenant covenants in this Lease to pay and to perform in the same manner and to the same extent and at the same time as if this Lease had not been terminated. In calculating the amounts to be paid by the Tenant under the foregoing covenant, the Tenant shall be credited with the net proceeds of any rent obtained by reletting the Premises, after deducting all the Landlord's reasonable expenses in connection with such reletting, including, without limitation, all repossession costs, brokerage commissions, fees for legal services and expenses of preparing the Premises for such reletting. The Tenant shall also be entitled to credit against the last periodic payments which would otherwise become due the amount, if any, paid to the Landlord as Lump Sum Payment. The Landlord shall use its best efforts to (i) relet the Premises, or any part or parts thereof, for a term or terms which may, at the Landlord's option, exceed or be equal to or less than the period which would otherwise have constituted the balance of the Term, and may grant such concessions and free rent, in each case as the Landlord in its reasonable commercial judgment considers advisable or necessary to relet the same, and (ii) make such alterations, repairs and improvements in the Premises as the Landlord in its reasonable commercial judgment considers advisable or necessary to relet the same. Provided Landlord complies with the terms of the preceding sentence, no action of the Landlord in accordance with the foregoing or failure to relet or to collect rent under reletting shall operate to release or reduce the Tenant's liability and the Landlord shall be entitled to seek to rent other properties of the Landlord prior to reletting the Premises. Section 9.3 - CUMULATIVE RIGHTS. The specific remedies to which the Landlord may resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress to which it may be lawfully entitled in case of any breach or threatened breach by the Tenant of any provisions of this Lease. In addition to the other remedies provided in this Lease, the Landlord shall be entitled to the restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease or to a decree compelling specific performance of any such covenants, conditions or provisions. Nothing contained in this Lease shall limit or prejudice the right of the Landlord to prove for and 23 27 obtain in proceedings for bankruptcy, insolvency or like proceedings by reason of the termination of 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, the damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above. Section 9.4 - LANDLORD'S SELF-HELP. If the Tenant shall at any time default in the performance of any obligation under this Lease, the Landlord shall have the right, but not the obligation, upon reasonable (but in no event less than ten (10) days') notice to the Tenant (except in case of emergency in which case no notice need be given), to perform such obligation unless Tenant shall have cured such default within such ten (10) day period. The Landlord may exercise its rights under this Section without waiving any other of its rights or releasing the Tenant from any of its obligations under this Lease. Section 9.5 - ENFORCEMENT EXPENSES. Each party hereto shall promptly reimburse the other for all costs and expenses, including without limitation reasonable legal fees, incurred by such party in exercising and enforcing its rights under this Lease following the other party's failure to comply with its obligations hereunder, whether or not such failure constitutes an Event of Default pursuant to Sections 9.1 or 9.7 hereof. Section 9.6 - LATE CHARGES AND INTEREST ON OVERDUE PAYMENTS. In the event that any payment of Annual Fixed Rent or Additional Rent shall remain unpaid for a period of ten (10) days after the same are due, there shall become due to the Landlord from the Tenant, as Additional Rent and as compensation for the Landlord's extra administrative costs in investigating the circumstances of late rent, a late charge of two percent (2%) of the amount overdue. In addition, any Annual Fixed Rent and Additional Rent not paid when due shall bear interest from the date due to the Landlord until paid at the variable rate (the "Default Interest Rate") equal to the higher of (i) the rate at which interest accrues on amounts not paid when due under the terms of the Landlord's financing for the Building, as from time to time in 24 28 effect, and (ii) one hundred and twenty-five percent (125%) of the Prime Rate (as defined in Section 3.3 (b) hereof). Section 9.7 - LANDLORD'S RIGHT TO NOTICE AND CURE. The Landlord shall in no event be in default in the performance of any of the Landlord's obligations hereunder unless and until the Landlord shall have failed to perform such obligations within twenty (20) days, or such additional time as is reasonably required to correct any such default (provided such breach is susceptible to cure and Landlord shall have commenced to cure within said twenty (20) days and shall diligently prosecute such cure to completion), after notice by the Tenant to the Landlord expressly specifying wherein the Landlord has failed to perform any such obligation. ARTICLE X MORTGAGEES' AND GROUND LESSORS' RIGHTS Section 10.1 - SUBORDINATION OF LEASE. This Lease and the estate of Tenant hereunder shall be subject and subordinate to any ground lease, deed of trust, mortgage lien or charge or any reciprocal easement agreement or other operating agreement which now encumber or which at any time hereafter may encumber the Premises (such ground lease, deed of trust, mortgage lien or charge, or any reciprocal easement agreement or other operating agreement and any replacement, renewal, modification, consolidation or extension thereof being hereinafter referred to as an "Encumbrance"). Any Encumbrance shall be prior and paramount to this Lease and to the right of Tenant hereunder and all persons claiming through and under Tenant, or otherwise, in the Premises. Tenant's acknowledgment and agreement of subordination provided for in this Section shall be self-operative and no further instrument of subordination shall be required. However, Tenant, on Tenant's behalf, and on behalf of all persons claiming through and under Tenant, covenants and agrees that, from time to time at the request of Landlord or the holder of any Encumbrance, Tenant will execute and deliver any necessary or proper instruments or certificates reasonably necessary to acknowledge or confirm the priority of the Encumbrance over this Lease and the subordination of this Lease thereto or to evidence Tenant's consent to any Encumbrance. Tenant agrees that it will not subordinate this 25 29 Lease to any other lien against the Property or the Premises without obtaining prior written consent from Landlord's lender, if any. Notwithstanding the foregoing, any holder of an Encumbrance may elect to the extent possible that this Lease shall have priority over such Encumbrance and, upon notification of such election by the holder of such Encumbrance, this Lease shall be deemed to have priority over such Encumbrance, whether this Lease is dated prior to or subsequent to the date of such Encumbrance. Section 10.2 - ATTORNMENT BY TENANT. Tenant agrees that if the holder of any Encumbrance or any persons claiming under said Encumbrance shall succeed to the interest of Landlord in this Lease, Tenant shall recognize and attorn to said holder as Landlord under the terms of this Lease. Tenant agrees that it will, upon the request of Landlord, execute, acknowledge and deliver any and all instruments necessary or desirable to give effect or notice of such attornment and failure of Tenant to execute any such document or instrument on demand shall constitute a default by Tenant under the terms of this Lease. If within twenty (20) days after submission of such instrument Tenant fails to execute the same, Landlord is hereby authorized to execute the same as attorney-in-fact for Tenant. Section 10.3. - AMENDMENT TO LEASE BY LANDLORD'S MORTGAGEE. In the event Landlord's mortgagee succeeds to the interest of Landlord in this Lease, and in the event such mortgagee is advised by its counsel that all or any portion of the Rent payable under this Lease is or may be deemed to be unrelated business income within the meaning of the Internal Revenue Code or regulations issued thereunder, such mortgagee may elect to amend unilaterally the calculation of Rent so that none of the Rent payable to such mortgagee under this Lease will constitute unrelated business income; PROVIDED, HOWEVER, in no event shall such amendment increase Tenant's payment obligations or other liability under the Lease or reduce the Landlord's obligations under this Lease. Tenant agrees to execute any document such mortgagee deems necessary to effect such amendment to this Lease in accordance with this Section 10.3. Section 10.4 - PREPAYMENT OF RENT NOT TO BIND MORTGAGEE. 26 30 No Annual Fixed Rent, Additional Rent, or any other charge payable to the Landlord shall be paid more than thirty (30) days prior to the due date thereof under the terms of this Lease and payments made in violation of this provision shall (except to the extent that such payments are actually received by a mortgagee or ground lessor) be a nullity as against such mortgagee or ground lessor and the Tenant shall be liable for the amount of such payments to such mortgagee or ground lessor. 27 31 Section 10.5 - TENANT'S DUTY TO NOTIFY MORTGAGEE; MORTGAGEE'S ABILITY TO CURE. No act or failure to act on the part of the Landlord which would entitle the Tenant, under the terms of this Lease, or any law, to be relieved of the Tenant's obligations to pay Annual Fixed Rent or Additional Rent hereunder or to terminate this Lease, shall result in a release or termination of such obligations of the Tenant or a termination of this Lease unless (i) the Tenant shall have first given written notice of the Landlord's act or failure to act to the Landlord's mortgagees or ground lessors, if any, of whose identity and address the Tenant shall have been given notice, specifying the act or failure to act on the part of the Landlord which would give basis to the Tenant's rights; and (ii) such mortgagees or ground lessors, after receipt of such notice, have failed or refused to correct or cure the condition complained of (if the condition complained of is susceptible to cure) within a reasonable time thereafter, which shall include a reasonable time for such mortgagee or ground lessors, to obtain possession of the Property if possession is necessary for the mortgagee or ground lessor to correct or cure the condition and if the mortgagee or ground lessor notifies the Tenant of its intention to take possession of the Property and correct or cure such condition. Section 10.6 - ESTOPPEL CERTIFICATES. The Tenant shall from time to time, upon not less than fifteen (15) days' prior written request by the Landlord and at Landlord's expense on a form provided by Landlord, execute, acknowledge and deliver to the Landlord a statement in writing certifying to the Landlord or an independent third party, with a true and correct copy of this Lease attached thereto, and provided that each of the following shall be true, (i) that this Lease is unmodified and in full force and effect (or, if there have been any modifications, that the same is in full force and effect as modified and stating the modifications); (ii) that the Tenant has no knowledge of any defenses, offsets or counterclaims against its obligations to pay the Annual Fixed Rent and Additional Rent and to perform its other covenants under this Lease (or if there are any defenses, offsets, or counterclaims, setting them forth in reasonable detail); (iii) that there are no known uncured defaults of the Landlord or the Tenant under this Lease (or if there are known defaults, setting them forth in reasonable detail); (iv) the dates to which the Annual Fixed Rent, Additional Rent and other charges have been paid; (v) that the Tenant 28 32 has accepted, is satisfied with, and is in full possession of the Premises, including all improvements, additions, and alterations thereto required to be made by Landlord under the Lease; (vi) that the Landlord has satisfactorily complied with all of the requirements and conditions precedent to the commencement of the Term of the Lease as specified in the Lease; (vii) the Term, the Commencement Date, and any other relevant dates and that the Tenant has been in occupancy since the Commencement Date and paying rent since the specified dates; (viii) that no monetary or other considerations, including, but not limited to, rental concessions for Landlord, special tenant improvements or Landlord's assumption of prior lease obligations of Tenant have been granted to Tenant by Landlord for entering into the Lease, except as specified; (ix) that Tenant has no notice of a prior assignment, hypothecation, or pledge of rents or of the Lease; (x) that the Lease represents the entire agreement between Landlord and Tenant; (xi) that no prepayment will be valid as to the party to whom such certificate is addressed without the consent of such party; (xii) that any notice to Tenant may be given it by certified or registered mail, return receipt requested, or delivered, at the Premises, or at another address specified; and (xiii) such other matters with respect to the Tenant and this Lease as the Landlord may reasonably request and are reasonably acceptable to Tenant's counsel. On the Commencement Date, the Tenant shall, at the request of the Landlord, promptly execute, acknowledge and deliver to the Landlord a statement in writing that the Commencement Date has occurred, that the Annual Fixed Rent has begun to accrue and that the Tenant has taken occupancy of the Premises. Any statement delivered pursuant to this Section may be relied upon by any prospective purchaser, mortgagee or ground lessor of the Premises and shall be binding on the Tenant. 29 33 ARTICLE XI CONDITION OF PREMISES Section 11.1 - CONDITION OF PREMISES. Tenant acknowledges that it is accepting the Premises in its present "as-is" condition with no expectation that Landlord will or should perform or contribute towards the cost of any leasehold improvements required to prepare the Premises for Tenant's occupancy. ARTICLE XII MISCELLANEOUS Section 12.1 - NOTICE OF LEASE. The Tenant agrees not to record this Lease, but upon request of either party, both parties shall execute and deliver a memorandum of this Lease in form appropriate for recording or registration, an instrument acknowledging the Commencement Date of the Term, and if this Lease is terminated before the Term expires, an instrument in such form acknowledging the date of termination. Section 12.2 - NOTICES. Whenever any notice, approval, consent, request, election, offer or acceptance is given or made pursuant to this Lease, it shall be in writing. Communications and payments shall be addressed, if to the Landlord, at the Landlord's Address for Notices as set forth in Exhibit A or at such other address as may have been specified by prior notice to the Tenant; and if to the Tenant, at the Tenant's Original Address or at such other place as may have been specified by prior notice to the Landlord. Any communication so addressed shall be deemed duly given on the earlier of (i) the date received or (ii) on the third business day following the day of mailing if mailed by registered or certified mail, return receipt requested. If the Landlord by notice to the Tenant at any time designates some other person to receive payments or notices, all payments or notices thereafter by the Tenant shall be paid or given to the agent 30 34 designated until notice to the contrary is received by the Tenant from the Landlord. Section 12.3 - SUCCESSORS AND LIMITATION ON LIABILITY OF THE LANDLORD. The obligations of this Lease shall run with the land, and this Lease shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the original landlord named herein and each successor landlord shall be liable only for obligations accruing during the period of its ownership. The obligations of the Landlord shall be binding upon the assets of the Landlord consisting of an equity ownership of the Property but not upon other assets of the Landlord and neither the Tenant, nor anyone claiming by, under or through the Tenant, shall be entitled to obtain any judgment creating personal liability on the part of the Landlord or enforcing any obligations of the Landlord against any assets of the Landlord other than an equity ownership of the Property. Section 12.4 - WAIVERS. The failure of the Landlord or the Tenant to seek redress for violation of, or to insist upon strict performance of, any covenant or condition of this Lease shall not be deemed a waiver of such violation nor prevent a subsequent act, which would have originally constituted a violation, from having all the force and effect of an original violation. The receipt by the Landlord of Annual Fixed Rent or Additional Rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver or such breach. No provision of this Lease shall be deemed to have been waived by either party. No consent or waiver, express or implied, by either party to or of any breach of any agreement or duty shall be construed as a waiver or consent to or of any other breach of the same or any other agreement or duty. Section 12.5 - ACCEPTANCE OF PARTIAL PAYMENTS OF RENT. No acceptance by the Landlord of a lesser sum than the Annual Fixed Rent and Additional Rent then due shall be deemed to be other than a partial installment of such rent due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as rent be deemed an accord and satisfaction, and the Landlord may accept such check or payment without prejudice to the Landlord's 31 35 right to recover the balance of such installment or pursue any other remedy in this Lease provided. The delivery of keys to any employee of the Landlord or to the Landlord's agent or any employee thereof shall not operate as a termination of this Lease or a surrender of the Premises. Section 12.6 - INTERPRETATION AND PARTIAL INVALIDITY. If any term of this Lease, or the application thereof to any person or circumstances, shall to any extent be invalid or unenforceable, the remainder of this Lease, or the application of such term to persons or circumstances other than those as to which it is invalid or unenforceable, shall not be affected thereby, and each term of this Lease shall be valid and enforceable to the fullest extent permitted by law. The titles of the Articles are for convenience only and not to be considered in construing this Lease. This Lease contains all of the agreements of the parties with respect to the subject matter thereof and supersedes all prior dealings between them with respect to such subject matter, and shall not be amended or modified, except by written instrument executed by the parties hereto. Section 12.7 - QUIET ENJOYMENT. So long as the Tenant pays Annual Fixed Rent and Additional Rent, performs all other Tenant covenants of this Lease and observes all conditions hereof, the Tenant shall peaceably and quietly have, hold and enjoy the Premises free of any claims by, through or under the Landlord. Section 12.8 - BROKERAGE. The Tenant represents and warrants that it has had no dealings with any broker or agent in connection with this Lease and shall indemnify and hold harmless the Landlord from claims for any brokerage commission arising out of the Tenant's actions. In the event of any claims against the Landlord predicated upon Tenant's breach of the foregoing representations and warranty the Tenant agrees to defend the same and indemnify and hold the Landlord harmless against any such claim. Section 12.9 - SURRENDER OF PREMISES AND HOLDING OVER. 32 36 The Tenant shall surrender possession of the Premises on the last day of the Term and the Tenant waives the right to any notice of termination or notice to quit.
