Such rights shall be always subject to the Rules and Regulations set forth in Exhibit E, attached hereto and incorporated herein by reference, as the same may be amended by the Landlord from time to time and such other reasonable written Rules and Regulations from time to time established by the Landlord by suitable notice to Tenant, which Rules and Regulations shall be uniformly enforced in a non-discriminatory manner, and to the right of the Landlord to designate and change from time to time such areas, facilities, fixtures and equipment.

The Term of this Lease shall commence on, and the Telin Commencement Date shall be, the earlier of (a) the date on which Landlord has substantially completed Landlord's Work as set forth in Section 3.3 below; or (b) the date on which Tenant commences beneficial use of the Premises. Tenant shall, in all events, be treated as having commenced beneficial use of the Premises when it begins to move into the Premises furniture and equipment for its regular business operations. There shall be no charge for Tenant's reasonable use of the Building's freight elevators during normal business hours in connection with Xxxxxx's move-in.

As soon as may be convenient after the Term Commencement Date has been determined, Landlord and Tenant agree to join with each other in the execution, in recordable form, of a written Declaration in which the Term Commencement Date and specified term of this Lease shall be stated.

3.2 DELIVERY OF PREMISES.

Tenant acknowledges that Xxxxxx has had an opportunity to inspect the Premises. Except as set forth hereinafter, the Premises, shall be delivered to Tenant As Is, Where Is, with all faults and without representation, warranty or guaranty of any kind by Landlord to Tenant, except as expressly provided herein. Landlord represents and warrants that, as of the date hereof, there are no violations of laws with respect to the Premises, the Building or the Lot and, as of the Commencement Date, all Building systems serving the Premises shall be in good working order and condition and in compliance with all laws. Prior to the Term Commencement Date, Landlord shall perform the work, if any, identified in Exhibit C ("Landlord's Work") attached hereto and incorporated herein and the Premises shall be delivered in broom clean condition.

Tenant shall pay an amount equal to all out-of-pocket costs incurred by Landlord as a result of any change orders signed by Xxxxxx and Landlord affecting Landlord's Work, which change orders shall specify the amount chargeable to Tenant on account of such change. Amounts due and payable on account of such change orders shall be paid by Tenant to Landlord within five (5) days after Landlord's invoice to Tenant therefor.

Landlord will not approve any construction, alterations, or additions requiring unusual expense to readapt the Premises to nominal office use on lease termination or increasing the cost of construction, insurance or taxes on the Building or of Landlord's services called for by Section 5.1 unless Tenant first gives assurances acceptable to Landlord that such readaptation will be made prior to such termination without expense to Landlord and makes provisions acceptable to Landlord for payment of such increased cost. Xxxxxxxx will also disapprove any alterations or additions requested by Tenant which will delay completion of the Premises. Tenant's construction, installation of furnishings, and later changes or additions shall be coordinated with any work being performed by Landlord in such manner as to maintain harmonious labor relations and not to damage the Building or Lot or interfere with Building operations.

3.3 PREPARATION OF PREMISES; PERFORMANCE OF LANDLORD WORK.

Xxxxxxxx agrees to use reasonable efforts to substantially complete Landlord's Work as soon as practicable, subject to delays beyond Landlord's reasonable control and delays caused by Tenant, but in any event, before June 1, 2005 (subject to extension for delays caused by Tenant). The Premises shall be deemed ready for occupancy on the date on which Landlord's Work is substantially completed as certified by Landlord's architect, with the exception of minor items which can be fully completed without material interference with Tenant and other items which because of the season or weather or the nature of the item are not practicable to do at the time, provided that none of said items is necessary to make the Premises tenantable for the Permitted Uses; provided, however, that if Landlord is unable to complete construction due to delay in Tenant's compliance with any of the provisions hereof or due to other delays caused by Tenant (including, without limitation, any changes to Landlord's Work requested by Xxxxxx), then the Premises shall be deemed ready for occupancy no later than the Scheduled Term Commencement Date.

3.4 GENERAL PROVISIONS APPLICABLE TO CONSTRUCTION.

All construction work required or permitted by this Lease, whether by Landlord or by Tenant, shall be done in a good and workmanlike manner and in compliance with all applicable laws and all lawful ordinances, regulations and orders of governmental authority and insurers of the Building and the Lot. Either party may inspect the work of the other at reasonable times and promptly shall give written notice of observed defects. Landlord's obligations under Sections 3.2 and 3.3, if any, shall be deemed to have been perfoiuied when Tenant commences to occupy any portion of the Premises for the Permitted Uses except for items which are incomplete or do not conform with the requirements of Section 3.1 and as to which Tenant shall in either case have given written notice to Landlord within three (3) weeks after such commencement. If Tenant shall not have commenced to occupy the Premises for the Permitted Uses within thirty (30) days after the Term Commencement Date, a certificate of completion by a licensed architect or registered engineer shall be conclusive evidence that Landlord has performed all such obligations except for items stated in such certificate to be incomplete or not in conformity with such requirements.

In no event shall any alterations or additions be considered or approved by Landlord which (a) involve or affect any structural or exterior element of the Building or building mechanical, electrical or plumbing systems, including the common facilities of the Building, or (b) require unusual expense to readapt the Premises to normal office use on Lease termination or increase the cost of construction or of insurance or taxes on the Building or the Lot. All alterations and additions shall become a part of the Premises, unless and until Landlord, at its option, shall specify the same for removal pursuant to Section 6.1.2 at the time of Tenant's request for Xxxxxxxx's consent. All of Tenant's alterations and additions and installation and delivery of telephone systems, furnishings, and equipment shall be coordinated with any work being performed by Landlord and shall be performed in such manner, and by such persons as shall maintain harmonious labor relations and not cause any damage to the Building or interference with Building construction or operation and, except for installation of furnishings, equipment and telephone systems, and except as otherwise expressly set forth herein, shall be performed by general contractors first approved by Landlord, which approval shall not be unreasonably withheld, conditioned or delayed. Before commencing any work Tenant shall: secure all licenses and permits necessary therefor; deliver to Landlord a statement of the names of all its contractors and subcontractors (the identity of which must have been previously approved by Landlord as hereinabove contemplated) and the estimated cost of all labor and material to be furnished by them; and cause each contractor to carry (i) worker's compensation insurance in statutory amounts covering all the contractor's and subcontractor's employees and (ii) comprehensive public liability insurance with such limits as Landlord may reasonably require, but in no event less than a combined single limit of $1,500,000 (all such insurance to be written by companies approved by Landlord and insuring Landlord and Tenant as well as the contractors), and to deliver to Landlord certificates of all such insurance. Xxxxxx agrees to pay promptly when due, and to defend and indemnify Landlord from and against, the entire cost of any work done on the Premises by Tenant, its agents, employees or independent contractors, and not to cause or permit any liens for labor or materials performed or furnished in connection therewith to attach to the Building or the Lot and immediately to discharge any such liens which may so attach.

As used herein, "Essential Capital Improvement" means any of the following:

(i) a labor saving device, energy saving device or other installation, improvement or replacement which reduces Operating Costs as referred to above, whether or not voluntary or required by governmental mandate; or

(ii) an installation, change, improvement, addition, alteration, or removal of any architectural barriers, whether or not the foregoing are structural in nature, made by reason of any governmental requirement first applicable after the Term Commencement Date if such governmental requirement is or will be applicable generally to similar office buildings; or

4.3 ESTIMATED ANNUAL OPERATING EXPENSE ESCALATION PAYMENT.

If, with respect to any fiscal year or fraction thereof during the Term, commencing on January 1, 2006, Landlord estimates that Tenant will be obligated to pay Tenant's Escalation Payment, then Tenant shall pay, as additional rent, on the first day of each month of such fiscal year and each ensuing fiscal year thereafter, an estimate equal to 1/12th of Tenant's Escalation Payment for the respective fiscal year ("Estimated Monthly Operating Cost Payments"), with an appropriate additional payment or refund to be made within 30 days after Landlord's Statement (as hereafter defined) is delivered to Tenant. Landlord may adjust such Estimated Monthly Operating Cost Payment from time to time and at any time during a fiscal year, and Tenant shall pay, as additional rent, on the first day of each month following receipt of Landlord's notice thereof, the adjusted Estimated Monthly Operating Cost Payment.

As soon as practicable after the end of each fiscal year ending during the Tenn and as soon as practicable after lease teunination, Landlord shall render a statement ("Landlord's Statement") in reasonable detail and according to usual accounting practices certified by Landlord and showing for the preceding fiscal year or fraction thereof, as the case may be, Landlord's Annual Operating Costs, Tenant's Proportionate Share thereof, and Tenant's Escalation Payment, as defined above. By notice given to Landlord no later than one hundred twenty (120) days after Xxxxxxxx's delivery of Landlord's Statement to Tenant, Tenant shall have the right to audit Landlord's books and reports relating thereto, at Tenant's expense, during normal business hours, such right exercisable by notice to Landlord given within such one hundred twenty (120) day period. To the extent such audit discloses errors in Landlord's Statement an appropriate adjustment shall be made and if such adjustment exceeds 5% of the charges payable under this Lease for the period in question, the Landlord shall pay for the reasonable cost of the audit.

4.4 ELECTRICITY.

Tenant will be billed for electricity for Tenant's lights and outlet consumption on a monthly basis based on an annual estimate of $1.25 per rentable square foot (which amount may be adjusted by Landlord, from time to time, to reflect increases in the actual out-of-pocket electrical costs to the Building). Should the actual average expense to Landlord per square foot for Tenant's electricity be different, an additional charge or a credit will be made within sixty (60) days following the end of each year's occupancy to be paid with or credited against the next monthly charge for Xxxxxx's electricity. Notwithstanding the foregoing, Landlord reserves the right to assess Xxxxxx's charge for electricity based on an engineer's survey of Tenant's electrical usage conducted from time to time or on the sub-metering of all or part of the Premises. Such charges for Xxxxxx's electricity shall be paid by Xxxxxx as additional rent at the same time and in the same manner as payments of Annual Rent.

Tenant covenants and agrees that its use of electric current shall not exceed 4.0 xxxxx per square foot of usable floor area and that its total connected lighting load will not exceed the maximum load from time to time permitted by applicable governmental regulations. In the event Tenant introduces into the Premises personnel or equipment which overloads the capacity of the Building's electrical system or in any other way interferes with the system's ability to perform properly, supplementary systems including check meters may, if and as needed, at Landlord's option, be provided by Landlord, at Tenant's expense. Landlord shall not in any way be liable or responsible to Tenant for any loss or damage or expense which Tenant may sustain or incur if, during the Term of this Lease, either the quantity or character of electric current is changed or electric current is no longer available or suitable for Tenant's requirements due to a factor or cause beyond Landlord's control.

Landlord reserves the exclusive right to provide electric and other utility service to the Building. Tenant may request permission from Landlord (which consent may be withheld in its sole discretion) to arrange electric and other utility service exclusively serving the Premises. Should such permission be granted, however, such service shall be installed only in such locations and in such manner as shall be specifically approved by Landlord in its sole discretion, Tenant shall be responsible for restoration of any damage caused by such installation and Tenant shall be responsible for removal of such installations at the termination of this Lease. Landlord may limit Tenant's choice of electrical or other utility providers in order to avoid proliferation of such services to the Building or for any other reason. In no event, however, shall Landlord be responsible for any damages or inconvenience caused by interruption in or poor quality of electricity or other utility services provided to the Building or the Premises unless such damages are caused by the negligence of Landlord, its agents or employees.

Landlord shall at its expense make all necessary repairs or alterations so as to constitute the remaining premises a complete architectural unit.

If more than twenty-five percent (25%) of the Premises shall be so taken or conveyed, then the Term shall cease only as respects the part so taken or conveyed, from the day possession shall be taken, and Tenant shall pay rent to that date with an appropriate refund by Landlord of such rent as may have been paid in advance for a period subsequent to the date of the taking of possession, but Landlord shall have the right to terminate this Lease upon notice to Tenant in writing within thirty (30) days after such taking of possession. If Landlord does not elect to terminate the Lease, all of the terms herein provided shall continue in effect except that the Annual Rent shall be equitably adjusted, and Landlord shall make all necessary repairs or alterations so as to constitute the remaining premises a complete architectural unit.

All compensation awarded for any such taking or conveyance, whether for the whole or a part of the Premises, shall be the property of Landlord, whether such damages shall be awarded as compensation for diminution in the value of the leasehold or of the fee of or underlying leasehold inferest in the Premises, and Tenant hereby assigns to Landlord all of Tenant's right, title and interest in and to any and all such compensation; provided, however, that Tenant shall be entitled to seek a separate award for Tenant's stock, trade fixtures and relocation expense.

In the event of any taking of the Premises or any part thereof for temporary use (i.e., less than nine (9) months), this Lease shall be and remain unaffected thereby and rent shall not xxxxx.

ARTICLE VIII

RIGHTS OF MORTGAGEE

8.1 PRIORITY OF LEASE.

This Lease is and shall continue to be subject and subordinate to any presently existing mortgage or deed of trust of record covering the Lot or Building or both (the "mortgaged premises"). The holder of any such presently existing mortgage or deed of trust shall have the election to subordinate the same to the rights and interests of Tenant under this Lease exercisable by filing with the appropriate recording office a notice of such election, whereupon the Tenant's rights and interests hereunder shall have priority over such mortgage or deed of trust.

Unless the option provided for in the next following sentence shall be exercised, this Lease shall be superior to and shall not be subordinate to, any mortgage, deed of trust or other voluntary lien hereafter placed on the mortgaged premises. The holder of any such mortgage, deed of trust or other voluntary lien shall have the option to subordinate this Lease to the same, provided that such holder enters into an agreement with Tenant by the terms of which the holder will agree to recognize the rights of Tenant under this Lease and to accept Tenant as tenant of the Premises under the terms and conditions of this Lease in the event of acquisition of title by such holder through foreclosure proceedings or otherwise and Tenant will agree to recognize the holder of such mortgage as Landlord in such event, which agreement shall be made to expressly bind and inure to the benefit of the successors and assigns of Tenant and of the holder and upon anyone purchasing the mortgaged premises at any foreclosure sale. Any such mortgage to which this Lease shall be subordinated may contain such provisions and conditions as the holder reasonably deems usual or customary.

8.2 RIGHTS OF MORTGAGE HOLDERS; LIMITATION OF MORTGAGEE'S LIABILITY.

The word "mortgage" as used herein includes mortgages, deeds of trust or other similar instruments evidencing other voluntary liens or encumbrances, and modifications, consolidations, extensions, renewals, replacements and substitutes thereof. The word "holder" shall mean a mortgagee, and any subsequent holder or holders of a mortgage. Until the holder of a mortgage shall enter and take possession of the Premises for the purpose of foreclosure, such holder shall have only such rights of Landlord as are necessary to preserve the integrity of this Lease as security. Upon entry and taking possession of the Premises for the purpose of foreclosure, such holder shall have all the rights of Landlord. Notwithstanding any other provision of this Lease to the contrary, including without limitation Section 10.4, no such holder of a mortgage shall be liable, either as mortgagee or as assignee, to perform, or be liable in damages for failure to perform any of the obligations of Landlord unless and until such holder shall enter and take possession of the Premises for the purpose of foreclosure, and such holder shall not in any event be liable to perform or for failure to perform the obligations of Landlord under Section 3.2. Upon entry for the purpose of foreclosure, such holder shall be liable to perform all of the obligations of Landlord (except for the obligations under Section 3.2), subject to and with the benefit of the provisions of Section 10.4, provided that a discontinuance of any foreclosure proceeding shall be deemed a conveyance under said provisions to the owner of the equity of the Premises.

8.3 INTENTIONALLY OMITTED.

8.4 NO PREPAYMENT OR MODIFICATION, ETC.

Tenant shall not pay Annual Rent, additional rent, or any other charge more than thirty (30) days prior to the due date thereof. No prepayment of Annual Rent, additional rent or other charge, no assignment of this Lease and no agreement to modify so as to reduce the rent, change the Term, or otherwise materially change the rights of Landlord under this Lease, or to relieve Tenant of any obligations or liability under this Lease, shall be valid unless consented to in writing by Xxxxxxxx's mortgagees of record, if any.

8.5 NO RELEASE OR TERMINATION.

No act or failure to act on the part of Landlord which would entitle Tenant under the terms of this Lease, or by law, to be relieved of Tenant's obligations hereunder or to ter urinate this Lease, shall result in a release or termination of such obligations or a termination of this Lease unless (i) Tenant shall have first given written notice of Landlord's act or failure to act to Landlord's mortgagees of record, if any, specifying the act or failure to act on the part of Landlord which could or would give basis to Tenant's rights and (ii) such mortgagees, after receipt of such notice, have failed or refused to correct or cure the condition complained of within a reasonable time thereafter, but nothing contained in this Section 8.5 shall be deemed to impose any obligation on any such mortgagee to correct or cure any such condition. "Reasonable time" as used above means and includes a reasonable time to obtain possession of the mortgaged premises, if the mortgagee elects to do so, and a reasonable time to correct or cure the condition if such condition is determined to exist.

8.6 CONTINUING OFFER.

The covenants and agreements contained in this Lease with respect to the rights, powers and benefits of a mortgagee (particularly, without limitation thereby, the covenants and agreements contained in this Article VIII) constitute a continuing offer to any person, corporation or other entity, which by accepting or requiring an assignment of this Lease or by entry or foreclosure assumes the obligations herein set forth with respect to such mortgagee; such mortgagee is hereby constituted a party to this Lease as an obligee hereunder to the same extent as though its name were written hereon as such; and such mortgagee shall be entitled to enforce such provisions in its own name. Xxxxxx agrees on request of Xxxxxxxx to execute and deliver from time to time any agreement which may reasonably be deemed necessary to implement the provisions of this Article VIII.

ARTICLE IX

DEFAULT

9.1 EVENTS OF DEFAULT.

If any default by Xxxxxx continues, in case of Annual Rent, additional rent or any other monetary obligation to Landlord for more than five (5) days after notice that the same is due (provided that no notice shall thereafter be required if Tenant defaults in any monetary obligation twice in any twelve (12) month period), or if Tenant fails to provide an estoppel certificate in accordance with Section 10.10 hereof, or if any default by Tenant continues in any other case for more than thirty (30) days after notice and such additional time, if any, as is reasonably necessary to cure the default if the default is of such a nature that it cannot reasonably be cured in thirty (30) days and Tenant promptly commences to cure such default and diligently pursues such cure without interruption to completion; or if Tenant becomes insolvent, fails to pay its debts as they fall due, files a petition under any chapter of the U.S. Bankruptcy Code, 11 U.S.C. 101 et seq., as it may be amended (or any similar petition under any insolvency law of any jurisdiction), or if such petition is filed against Tenant; or if Tenant proposes any dissolution, liquidation, composition, financial reorganization or recapitalization with creditors, makes an assignment or trust mortgage for benefit of creditors, or if a receiver, trustee, custodian or similar agent is appointed or takes possession with respect to any property of Tenant; or if the leasehold hereby created is taken on execution or other process of law in any action against Tenant; then, and in any such case, Landlord and the agents and servants of Landlord may, in addition to and not in derogation of any remedies for any preceding breach of covenant, immediately or at any time thereafter while such default continues and without further notice, at Landlord's election, do any one or more of the following: (1) give Tenant written notice stating that the Lease is terminated, effective upon the giving of such notice or upon a date stated in such notice, as Landlord may elect, in which event the Lease shall be irrevocably extinguished and terminated as stated in such notice without any further action, or (2) with or without process of law, in a lawful manner enter and repossess the Premises as of Landlord's former estate, and expel Tenant and those claiming through or under Tenant, and remove its and their effects, without being guilty of trespass, in which event the Lease shall be irrevocably extinguished and terminated at the time of such entry, or (3) pursue any other rights or remedies permitted by law. Any such termination of the Lease shall be without prejudice to any remedies which might otherwise be used for arrears of rent or prior breach of covenant, and in the event of such termination Tenant shall remain liable under this Lease as hereinafter provided. Tenant hereby waives all statutory rights (including, without limitation, rights of redemption, if any) to the extent such rights may be lawfully waived, and Landlord, without notice to Tenant, may store Tenant's effects and those of any person claiming through or under Tenant at the expense and risk of Tenant and, if Landlord so elects, may sell such effects at public auction or private sale and apply the net proceeds to the payment of all sums due to Landlord from Tenant, if any, and pay over the balance, if any, to Tenant.

9.2 TENANT'S OBLIGATIONS AFTER TERMINATION.

In the event that this Lease is terminated under any of the provisions contained in Section 9.1 or shall be otherwise terminated for breach of any obligation of Tenant, Tenant covenants to pay forthwith to Landlord, as compensation, discounted to present value, the excess of the total rent reserved for the residue of the Teiiii over the rental value of the Premises for said residue of the Term. In calculating the rent reserved, there shall be included, in addition to the Annual Rent and all additional rent, the value of all other consideration agreed to be paid or performed by Xxxxxx for said residue. Tenant further covenants as an additional and cumulative obligation after any such ending to pay punctually to Landlord all the sums and perform all the obligations which 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 Tenant under the next foregoing covenant, Tenant shall be credited with any amount paid to Landlord as compensation as provided in the first sentence of this Section 9.2 and also with the net proceeds of any rents obtained by Landlord by reletting the Premises, after deducting all Landlord's expenses in connection with such reletting, including, without implied limitation, all repossession costs, brokerage commissions, fees for legal services and expenses of preparing the Premises for such reletting, it being agreed by Tenant that Landlord may (i) relet the Premises or any part or parts thereof for a term or terms which may at Landlord's option be equal to or less than or exceed the period which would otherwise have constituted the balance of the Teiin and may grant such concessions and free rent as Landlord in its sole judgment considers advisable or necessary to relet the same and (ii) make such alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable or necessary to relet the same, and no action of Landlord in accordance with the foregoing or failure to relet or to collect rent under reletting shall operate or be construed to release or reduce Tenant's liability as aforesaid.

So long as at least twelve (12) months of the Telin remain unexpired at the time of such termination, in lieu of any other damages or indemnity and in lieu of full recovery by Landlord of all sums payable under all the foregoing provisions of this Section 9.2, Landlord may by written notice to Tenant, at any time after this Lease is terminated under any of the provisions contained in Section 9.1, or is otherwise terminated for breach of any obligation of Tenant and before such full recovery, elect to recover and Tenant shall thereupon pay, as liquidated damages, an amount equal to the aggregate of the Annual Rent and additional rent accrued under Article IV in the 12 months ended next prior to such termination plus the amount of Annual Rent and additional rent of any kind accrued and unpaid at the time of termination and less the amount of any recovery by Landlord under the foregoing provisions of this Section 9.2 up to the time of payment of such liquidated damages.

Nothing contained in this Lease shall, however, limit or prejudice the right of Landlord to prove and obtain in proceedings for bankruptcy or insolvency 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.

ARTICLE X

MISCELLANEOUS

10.1 NOTICE OF LEASE.

Upon request of either party, both parties shall execute and deliver, after the Term begins, a notice of this Lease in form appropriate for recording or registration, and if this Lease is terminated before the Term expires, an instrument in such form acknowledging the date of termination.

10.2 (Intentionally Omitted)

10.3 NOTICES FROM ONE PARTY TO THE OTHER,

All notices required or permitted hereunder shall be in writing and addressed, if to the Tenant, at Xxxxxx's Address or such other address as Tenant shall have last designated by notice in writing to Landlord and, if to Landlord, at Xxxxxxxx's Address or such other address as Landlord shall have last designated by notice in writing to Tenant. Any notice shall have been deemed duly given if mailed to such address postage prepaid, registered or certified mail, return receipt requested, when deposited with the U.S. Postal Service, or if delivered to such address by hand, when so delivered.

10.4 BIND AND INURE.

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 Landlord named herein and each successive owner of the Premises shall be liable only for the obligations accruing during the period of its ownership. The obligations of Landlord shall be binding upon the assets of Landlord which comprise the Building and the Lot but not upon other assets of Landlord. No individual partner, member, trustee, stockholder, officer, director, employee or beneficiary of Landlord shall be personally liable under this Lease and Tenant shall look solely to Landlord's interest in the Building and the Lot in pursuit of its remedies upon an event of default hereunder, and the general assets of the individual partners, trustees, stockholders, officers, employees or beneficiaries of Landlord shall not be subject to levy, execution or other enforcement procedure for the satisfaction of the remedies of Tenant.

10.5 NO SURRENDER.

The delivery of keys to any employee of Landlord or to Landlord's agent or any employee thereof shall not operate as a termination of this Lease or a surrender of the Premises.

10.6 NO WAIVER, ETC.

The failure of Landlord to seek redress for violation of, or to insist upon the strict performance of any covenant or condition of this Lease or any of the Rules and Regulations referred to in Section 6.1.4, whether heretofore or hereafter adopted by Landlord, 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, nor shall the failure of Landlord to enforce any of said Rules and Regulations against any other tenant in the Building be deemed a waiver of any such Rules or Regulations. The receipt by Landlord of Annual Rent or additional rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach by Landlord, unless such waiver be in writing and signed by Landlord. No consent or waiver, express or implied, by Landlord 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.

10.7 NO ACCORD AND SATISFACTION.

No acceptance by Landlord of a lesser sum than the Annual Rent and additional rent then due shall be deemed to be other than on account of the earliest 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 as accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord's right to recover the balance of such installment or pursue any other remedy in this Lease provided.

10.8 CUMULATIVE REMEDIES.

The specific remedies to which 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 Tenant of any provisions of this Lease. In addition to the other remedies provided in this Lease, 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.

10.9 LANDLORD'S RIGHT TO CURE.

If Tenant shall at any time default in the performance of any obligation under this Lease beyond applicable notice and cure periods (provided that no notice or cure period need be provided in the event of an emergency), Landlord shall have the right, but shall not be obligated, to enter upon the Premises and to perform such obligation, notwithstanding the fact that no specific provision for such substituted performance by Landlord is made in this Lease with respect to such default. In performing such obligation, Landlord may make any payment of money or perform any other act. All sums so paid by Xxxxxxxx (together with interest at the rate of 4% per annum in excess of the then prime commercial rate of interest being charged by the three largest national banks in Boston, Massachusetts) and all necessary out-of-pocket costs and expenses in connection with the performance of any such act by Landlord, shall be deemed to be additional rent under this Lease and shall be payable to Landlord immediately within five (5) days following written demand therefor. Landlord may exercise the foregoing rights without waiving any other of its rights or releasing Tenant from any of its obligations under this Lease.

10.10 ESTOPPEL CERTIFICATE.

Tenant and Landlord agree, from time to time, upon not less than 15 days' prior written request, to execute, acknowledge and deliver to the other a statement in writing certifying that this Lease is unmodified and in full force and effect; that Tenant has no defenses, offsets or counterclaims against its obligations to pay the Annual Rent and additional rent and to perform its other covenants under this Lease; that there are no uncured defaults of Landlord or Tenant under this Lease (or, if there have been modifications, that this Lease is in full force and effect as modified and stating the modifications, and, if there are any defenses, offsets, counterclaims, or defaults, setting them forth in reasonable detail); and the dates to which the Annual Rent, additional rent and other charges have been paid. Any such statement delivered pursuant to this Section 10.10 shall be in a foifli reasonably acceptable to and may be relied upon by any prospective purchaser or mortgagee of premises which include the Premises or any prospective assignee of any such mortgagee, or any prospective assignee, purchaser or lender of Tenant.

10.11 WAIVER OF SUBROGATION.

Any insurance carried by either party with respect to the Premises and property therein or occurrences thereon shall 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 occurrences 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 due to hazards covered by insurance containing such clause or endorsement to the extent of the insurance coverages required to be maintained hereunder.

10.12 ACTS OF GOD.

In any case where either party hereto is required to do any act, delays caused by or resulting from Acts of God, war, civil commotion, fire, flood or other casualty, labor difficulties, shortages of labor, materials or equipment, government regulations, unusually severe weather, or other causes beyond such party's reasonable control shall not be counted in deteimining the time during which work shall be completed, whether such time be designated by a fixed date, a fixed time or a "reasonable time," and such time shall be deemed to be extended by the period of such delay.

10.13 BROKERAGE.

Tenant and Landlord represent and warrant that they dealt with no brokers in connection with this transaction other than the Broker and agree to defend, with counsel approved by the other, indemnify and save the other harmless from and against any and all cost, expense or liability for any compensation, commissions or charges claimed by a broker or agent, other than the Broker in connection with this Lease. Xxxxxxxx xxxxxx agrees to pay the brokerage fees to the Broker in connection with the execution and delivery of this Lease.

10.14 SUBMISSION NOT AN OFFER.

The submission of a draft of this Lease or a summary of some or all of its provisions does not constitute an offer to lease or demise the Premises, it being understood and agreed that neither Landlord nor Tenant shall be legally bound with respect to the leasing of the Premises unless and until this Lease has been executed by both Landlord and Tenant and a fully executed copy has been delivered to each of them.

10.15 APPLICABLE LAW AND CONSTRUCTION.

This Lease shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts. If any term, covenant, condition or provision of this Lease or the application thereof to any person or circumstances shall be declared invalid or unenforceable by the final ruling of a court of competent jurisdiction having final review, the remaining terms, covenants, conditions and provisions of this Lease and their application to persons or circumstances shall not be affected thereby and shall continue to be enforced and recognized as valid agreements of the parties, and in the place of such invalid or unenforceable provision, there shall be substituted a like, but valid and enforceable provision which comports to the findings of the aforesaid court and most nearly accomplishes the original intention of the parties.

There are no oral or written agreements between Landlord and Tenant affecting this Lease. This Lease may be amended, and the provisions hereof may be waived or modified, only by instruments in writing executed by Landlord and Xxxxxx.

The titles of the several Articles and Sections contained herein are for convenience only and shall not be considered in construing this Lease.

Unless repugnant to the context, the words "Landlord" and "Tenant" appearing in this Lease shall be construed to mean those named above and their respective heirs, executors, administrators, successors and assigns, and those claiming through or under them respectively. If there be more than one tenant, the obligations imposed by this Lease upon Tenant shall be joint and several.

10.16 AUTHORITY OF TENANT.

Tenant represents and warrants to Landlord (which representations and warranties shall survive the delivery of this Lease) that: (a) Tenant (i) is duly organized, validly existing and in good standing under the laws of its state of incorporation, (ii) has the corporate power and authority to carry on businesses now being conducted and is qualified to do business in every jurisdiction where such qualification is necessary and (iii) has the corporate power to execute and deliver and perform its obligations under this Lease and (b) the execution, delivery and performance by Tenant of its obligations under this Lease have been duly authorized and will not violate any provision of law, any order of any court or other agency of government, the corporate charter or by-laws of the Tenant or any indenture, agreement or other instrument to which it is a party or by which it is bound.

ARTICLE XI

SECURITY DEPOSIT

Simultaneously with Xxxxxx's delivery of the executed Lease to Landlord, Tenant will deliver to Landlord the Security Deposit in the form of cash or a letter of credit in the amount of the Security Deposit and in conformity with the provisions set forth below (the "Letter of Credit"), which Security Deposit shall be held by Landlord, as security, without interest, for and during the Term, and which Security Deposit shall be returned to Tenant at the termination of this Lease, provided there exists no default of Tenant under the provisions of this Lease. If a Letter of Credit is provided as the Security Deposit, the Letter of Credit shall be an irrevocable and unconditional standby documentary letter of credit in the amount of the Security Deposit issued by a institution satisfactory to Landlord in its reasonable discretion, naming Landlord, its successors and assigns as the beneficiary, assignable to a successor or assignee at no cost to Landlord or such successor or assignee, expiring no less than one (1) year from the Term Commencement Date and renewing automatically each year (or at the end of the applicable tem' thereof) unless the issuing bank has given Landlord notice at least forty-five (45) days prior to the expiration that the same will not be renewed, and otherwise in form and substance reasonably acceptable to Landlord. Landlord shall be permitted to draw upon the Letter of Credit in the event of (i) default by Tenant in any of its obligations hereunder after the giving of any required notice and the expiration of any applicable cure period, in which event Landlord may draw upon all or a portion of the Letter of Credit and apply the proceeds as described below, or (ii) failure by Tenant to provide to Landlord a replacement or substitute Letter of Credit in the amount of Security Deposit, and otherwise subject to the conditions set forth above, no less than thirty (30) days prior to the expiration date of the Letter of Credit then held by Landlord, in which event Landlord may draw upon all of the Letter of Credit and use the same to satisfy any unfulfilled obligation of Tenant under the Lease, without any obligation to segregate such funds or to account for them to Tenant, Tenant acknowledging that in such circumstance it shall have no right whatsoever to such proceeds. Such failure to provide a replacement or substitute Letter of Credit to Landlord no less than thirty (30) days prior to the expiration date of the Letter of Credit then held by Landlord shall be an event of default hereunder.

The Security Deposit is being delivered by Tenant to Landlord as security for the faithful performance and observance by Tenant of the terms, provisions and conditions of this Lease. It is understood and agreed that if any default by Tenant occurs hereunder and continues after the giving of any required notice and the expiration of any applicable cure period, Landlord may use, apply or retain the whole or any part of the Security Deposit so deposited to the extent required to cure such default or for payment of any sum as to which Tenant is in such default, if any, or for any sum which Landlord may expend or may be required to expend by reason of any such default by Tenant hereunder, if any. It is agreed that Landlord shall always have the right to apply the Security Deposit or any part thereof, as aforesaid, without prejudice to any other remedy or remedies which Landlord may have, or Landlord may pursue any other such remedy or remedies in lieu of applying the Security Deposit. If all or any part of the Security Deposit is applied to an obligation of Tenant hereunder, Tenant shall immediately upon request by Landlord restore the Security Deposit to its original amount. Tenant shall not have the right to call upon Landlord to apply all or any part of the Security Deposit to cure any default or fulfill any obligation of Tenant, but such use shall be solely in the discretion of Landlord. Upon any conveyance by Landlord of its interest under this Lease, the Security Deposit may be delivered by Landlord to Landlord's grantee or transferee. Upon any delivery, Tenant hereby releases Landlord herein named of any and all liability with respect to such Security Deposit and agrees to look solely to such grantee or transferee. It is further understood that this provision shall also apply to subsequent grantees and transferees.
