Upon not less than thirty (30) days prior written notice to Tenant, Landlord shall have the right from time to time to change the periods of accounting under this Section 4.2 to any annual period other than the Fiscal Year and upon any such change all items referred to in this Section shall be appropriately apportioned. In all Landlord's Statements, rendered under this Section, amounts for periods partially within and partially without the accounting periods shall be appropriately apportioned, and any -9- 12 items which are not determinable at the time of a Landlord's Statement shall be included therein on the basis of Landlord's reasonable estimate, and with respect thereto Landlord shall render promptly after determination a supplemental Landlord's Statement, and appropriate adjustment shall be made according thereto. All Landlord's Statements shall be prepared on an accrual basis of accounting.

In case Landlord is prevented or delayed from making any repairs, alterations or improvements, or furnishing any service or performing any other covenant or duty to be performed on Landlord's part, by reason of any cause reasonably beyond Landlord's control, Landlord shall not be liable to Tenant therefor, nor, except as expressly otherwise provided herein and in Article VII, shall Tenant be entitled to any abatement or reduction of rent by reason thereof, nor shall the same give rise to a claim in Tenant's favor that such failure constitutes, actual or constructive, total or partial, eviction from the Premises. Landlord shall use reasonable diligence to make or cause to be made such repairs as may be required to machinery or equipment within the Building or on the Lot to -11- 14 provide restoration of services and when a cessation or interruption of service has occurred due to circumstances or conditions beyond the boundaries of the Lot or beyond Landlord's direct control, to cause the same to be restored to the extent such restoration is within Landlord's control, and otherwise, by diligent application or request to the provider thereof. Landlord also agrees to use reasonable efforts to avoid unnecessary inconvenience to Tenant by reason thereof and agrees, where reasonable, not to perform such work during normal business hours. In the event Landlord fails to provide or cause to be provided any one or more of the Building Services, and such failure causes the premises or a portion thereof, to be rendered untenantable for the purpose of conducting Tenant's business operations, and such conditions shall continue, in the case of circumstances or conditions within Landlord's direct control, for any four (4) consecutive business days or such condition shall occur in any seven (7) business days during any thirty (30) day period, or in the case of circumstances or conditions beyond or outside of Landlord's direct control for seven (7) consecutive business days or such condition shall occur in any ten (10) business days during any thirty (30) day period, Tenant shall have the right to xxxxx the portion of Fixed Rent which corresponds to the portion of the Premises rendered untenantable. Notwithstanding the foregoing, any such abatement of Fixed Rent shall be limited to twenty percent (20%) of the Monthly Fixed Rent in any month, such monthly twenty percent (20%) of Fixed Rent abatement to continue until Tenant has been fully reimbursed by such partial abatement for its abatement due for each day that the Premises was rendered fully or partially untenantable beyond the applicable period of four (4), seven (7) or ten (10) days until the full amount of such abatement due Tenant has been recovered by Tenant through such monthly partial abatement or by other payment to Tenant by Landlord. Landlord reserves the right to stop any service or utility system when necessary by reason of accident or emergency or until necessary repairs have been completed. Except in case of emergency repairs, Landlord will give Tenant reasonable advance notice of any contemplated stoppage and will use reasonable efforts to avoid unnecessary inconvenience to Tenant by reason thereof.

ARTICLE VII CASUALTY AND TAKING 7.1 CASUALTY AND TAKING In case during the Term all or any substantial part of the Premises, the Building, or Lot or any one or more of them, are damaged materially by fire or any other cause or by action of public or other authority in consequence thereof such that in Landlord's estimate it will take 120 days or longer to restore the Premises, Building or Lot to its prior condition, or are taken by eminent domain or Landlord receives compensable damage by reason of anything lawfully done in pursuance of public or other authority, this Lease shall terminate at either Tenant's or Landlord's election, which may be made as to Landlord, notwithstanding Landlord's entire interest may have been divested, by notice given to Tenant within 30 days after the occurrence of the event giving rise to the election to terminate, or if by Tenant within 30 days of notice by Landlord that such restoration will require 120 days or longer to complete, or notice by Landlord of such taking. Either such notice shall specify the effective date of termination which shall be not less than 30, nor more than 60, days after the date of notice of such termination. In the event that such substantial and material casualty occurs within the last 180 days of the Term and Tenant has not exercised its extension option, then if a substantial portion of the Premises is rendered untenantable for the normal conduct of Tenant's business for -18- 21 a period of greater than 60 days, then Tenant shall have the right to terminate this Lease by notice to Landlord, such notice to be given and exercised as set forth in the previous sentence. If in any such case the Premises are rendered unfit for use and occupation or untenantable for the normal conduct of Tenant's business, and the Lease is not so terminated, Landlord shall use due diligence to put the Premises, or, in case of taking, what may remain thereof (excluding any items installed or paid for by Tenant which Tenant may be required or permitted to remove) into proper condition for use and occupation to the extent permitted by the net award of insurance or damages in at least as good a condition as at the commencement of the Term giving due consideration to wear and tear, and a just proportion of the Fixed Rent and Additional Rent according to the nature and extent of the injury shall be abated until the Premises or such remainder shall have been put by Landlord in such condition; and in case of a taking which permanently reduces the area of the Premises, a just proportion of the Fixed Rent and Additional Rent shall be abated for the remainder of the Term and an appropriate adjustment shall be made to the Annual Estimated Operating Expenses. 7.2 RESERVATION OF AWARD Landlord reserves to itself any and all rights to receive awards made for damages to the Premises, Building or Lot and the leasehold hereby created, or any one or more of them, accruing by reason of exercise of eminent domain or by reason of anything lawfully done in pursuance of public or other authority. Tenant hereby releases and assigns to Landlord all Tenant's rights to such awards, and covenants to deliver such further assignments and assurances thereof as Landlord may from time to time request, hereby irrevocably designating and appointing Landlord as its attorney-in-fact to execute and deliver in Tenant's name and behalf all such further assignments thereof. It is agreed and understood, however, that Landlord does not reserve to itself, and Tenant does not assign to Landlord, any damages payable for (i) movable trade fixtures installed by Tenant or anybody claiming under Tenant, at its own expense, or (ii) relocation expenses recoverable by Tenant from such authority in a separate action. ARTICLE VIII RIGHTS OF MORTGAGEE 8.1 PRIORITY OF LEASE Prior to the date hereof, Landlord shall cause to be obtained non-disturbance and attornment agreements, in customary form, from all existing mortgage holders. Landlord shall have the option to subordinate this Lease to any mortgagee or deed of trust of the Lot or Building, or both ("the mortgaged premises"), provided that the holder thereof 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 -19- 22 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 terms, provisions and conditions as the holder deems usual or customary. Unless Landlord exercises such option, this Lease shall be superior to and shall not be subordinated to any mortgage or other voluntary lien or other encumbrance on the mortgaged premises. 8.2 LIMITATION ON MORTGAGEE'S LIABILITY Upon entry and taking possession of the mortgaged premises for any purpose other than foreclosure, the holder of a mortgage shall have all rights of Landlord, and during the period of such possession, the duty to perform all Landlord's obligations hereunder. Except during such period of possession, no such holder shall be liable, either as mortgagee or as holder of a collateral assignment of this Lease, 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 mortgaged premises for the purpose of foreclosing a mortgage. Upon entry for the purpose of foreclosing a mortgage, such holder shall be liable to perform all of the obligations of Landlord, subject to the provisions of Section 8.3 provided that a discontinuance of any foreclosure proceeding shall be deemed a conveyance under the provisions of Section 10.5 to the owner of the equity of the mortgaged premises. 8.3 NO PREPAYMENT OR MODIFICATION, ETC. No Fixed Rent, additional rent, or any other charge shall be paid more than 30 days prior to the due dates thereof, and payments made in violation of this provision shall (except to the extent that such payments are actually received by a mortgagee in possession or in the process of foreclosing its mortgage) be a nullity as against such mortgagee, and Tenant shall be liable for the amount of such payments to such mortgagee. No assignment of this Lease and no agreement to make or accept any surrender, termination or cancellation 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 Landlord's mortgagees of record, if any. 8.4 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 terminate 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 -20- 23 Landlord's act or failure to act to Landlord's mortgagees of which Landlord has given Tenant notice, together with the address therefor, 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 8.4 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. The current mortgagee is Teachers Insurance and Annuity Association, Attention: Mortgage Department, 000 Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000. 8.5 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, and such mortgagee shall be entitled to enforce such provisions in its own name. Tenant agrees on request of Landlord to execute and deliver from time to time any agreement which may reasonably be deemed necessary to implement the provisions of this Article VIII. 8.6 SUBMITTAL OF FINANCIAL STATEMENT At any time and from time to time during the term of this Lease, within 15 days after request therefor by Landlord, no more often than annually Tenant shall supply to Landlord and/or any Mortgagee a current financial statement or such other financial information as may be reasonably required by any such party. ARTICLE IX DEFAULT 9.1 EVENTS OF DEFAULT If any default by Tenant continues after notice, in case of Fixed Rent or additional rent for more than ten days, or in any other case for more than 30 days 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 30 days; or if Tenant or Guarantor makes any assignment for the benefit of creditors, or files a petition under any bankruptcy or insolvency law; or if such a petition is filed against Tenant or any Guarantor and is not dismissed within 90 days; or if a receiver or similar officer becomes -21- 24 entitled to Tenant's leasehold hereunder and it is not returned to Tenant within 90 days, or if such leasehold is taken on execution or other process of law in any action against Tenant then, and in any such cases, 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 and with process of law enter into and upon the Premises or any part thereof in the name of the whole or mail a notice of termination addressed to Tenant at the Premises and repossess the same as of Landlord's former estate and expel Tenant and those claiming through or under Tenant and remove its and their effects without being deemed guilty of any manner of trespass and without prejudice to any remedies which might otherwise be used for arrears of rent or prior breach of covenant, and upon such entry or mailing as aforesaid, this Lease shall terminate, but Tenant shall remain liable 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 after written notice to Tenant, 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, the excess of the total rent reserved for the residue of the Term 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 Fixed Rent and all additional rent, the value of all other consideration agreed to be paid or performed by Tenant 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 reasonable expenses in connection with such reletting, including, without implied limitation, all repossession costs, brokerage commissions, fees for legal services and expense 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 Term 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 -22- 25 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. 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 TITLES The titles of the Articles are for convenience and are not to be considered in construing this Lease. 10.2 NOTICE OF LEASE Both parties shall execute and deliver, after the Term begins, a short form of this Lease in a form appropriate for recording or registration, and upon request of either party if this Lease is terminated before the Term expires, an instrument in such form acknowledging the date of termination. 10.3 RELOCATION Intentionally Omitted. 10.4 NOTICES FROM ONE PARTY TO THE OTHER No notice, approval, consent requested or election required or permitted to be given or made pursuant to this Lease shall be effective unless the same is in writing.

Any communication so addressed shall be deemed duly served if mailed by registered or certified mail, return receipt requested and shall be deemed to have been given two (2) business days after it has been so mailed. -23- 26 10.5 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. Neither the Landlord named herein nor any successive owner of the Premises whether an individual, trust, a corporation or otherwise shall have any personal liability beyond their equity interest in the Premises. 10.6 NO SURRENDER The delivery of keys to any employees 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. 10.7 NO WAIVER, ETC. The failure of Landlord or of Tenant to seek redress for violation of, or to insist upon the strict performance of any covenant or condition of this Lease or, with respect to such failure of Landlord, 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 Fixed 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 signed by Landlord. No consent or waiver, express or implied, by Landlord or Tenant 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. 10.8 NO ACCORD AND SATISFACTION No acceptance by Landlord of a lesser sum than the Fixed 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. -24- 27 10.9 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. 10.10 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. 10.11 LANDLORD'S RIGHT TO CURE If Tenant shall at any time default in the performance of any obligation under this Lease, which default continues after giving of any required notice and the expiration of any applicable grace period, 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 Landlord (together with interest at the rate of the prime rate as determined by a major Boston bank selected by Landlord, plus 3% (i.e., prime plus 3%) per annum, and all necessary incidental costs and expenses in connection with the performance of any such acts by Landlord, shall be deemed to be additional rent under this Lease and shall be payable to Landlord within thirty (30) days of demand. Landlord may exercise the foregoing rights without waiving any other of its rights or releasing Tenant from any of its obligations under this Lease. Similarly, if Landlord shall at any time default in the performance of any material obligation under this Lease, which default continues after giving of any required notice and the expiration of any applicable grace period, Tenant shall have the right, after 30 days notice to Landlord and Landlord's mortgagee, but shall not be obligated, to perform such obligation, notwithstanding the fact that no specific provision for such substituted performance by Tenant is made in this Lease with respect to such material default. In performing such obligation, Tenant may make any payment of money or perform any other act. All reasonable sums so paid by Tenant (together with interest at the rate of the prime rate as determined by a major Boston bank selected by Tenant, plus 3% (i.e., -25- 28 prime plus 3%) per annum, and all necessary incidental costs and expenses in connection with the performance of any such acts by Tenant shall be payable to Tenant within thirty (30) days of demand.

Any such statements delivered pursuant to this Section 10.12 may be relied upon by any prospective purchaser or mortgage of premises which include the Premises or any prospective assignee of any such mortgagee. 10.13 WAIVER OF SUBROGATION Any insurance carried by either party with respect to the Premises and property therein or occurrences thereon, shall if the other party so requests and it can be so written without additional premium or with any additional premium which the other party agrees 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.

Tenant is responsible for the maintenance and repair of plumbing fixtures and related equipment installed in the leased premises for its exclusive use (such as in coffee room, cafeteria or employee exercise area). Page 3 of 3 33 VII. ELECTRICITY 1. Tenant shall pay for all electricity consumed in Tenant's space. If not metered separately, Landlord shall reasonably estimate the cost of such electrical usage for Tenant's lights and plugs, and Tenant shall reimburse Landlord for such costs on a monthly basis. If Tenant's use of electrical energy in Tenant's Space is disproportionate to other tenants' use of electrical energy, Tenant shall also pay for all excess electricity consumed in Tenant's space as estimated by Landlord. If Tenant is billed in any manner for tenant electricity other than as Estimated Cost of Tenant Electrical Service to Tenant's space (included in Fixed Rent) as set forth in Paragraph 1.1 hereof, the Fixed Rent shall be adjusted by deducting the portion thereof representing the cost of electrical service to Tenant's Space. Tenant's use of electrical energy in Tenant's space shall not at any time exceed the capacity of any of the electrical conductors or equipment in or otherwise serving Tenant's space. To ensure that such capacity is not exceeded and to avert possible adverse effects upon the Building's electrical system, Tenant shall not, without prior written notice to Landlord in each instance, connect to the Building electric distribution system any fixtures, appliances or equipment which operates on a voltage in excess of 120 or 208 volts nominal or make any alteration or addition to the electric system of the Tenant's space. Unless Landlord shall reasonably object to the connection of any such fixtures, appliances or equipment, all additional risers or other equipment required therefore shall be provided by Landlord and the cost thereto shall be paid by Tenant upon Landlord's demand. 34 EXHIBIT "E" RULES AND REGULATIONS 1. The entrance, lobbies, passages, corridors, elevators and stairways shall not be encumbered or obstructed by Tenant, Tenant's agents, servants, employees, licensees, and visitors be used by them for any purpose other than for ingress and egress to and from the Premises. The moving in or out of all safes, freight, furniture, or bulky matter of any description must take place during the hours which Landlord may reasonably determine from time to time. Landlord reserves the right to inspect all freight and bulky matter to be brought into the Building and to exclude from the Building all freight and bulky matter which violates any of these Rules and Regulations or the Lease of which these Rules and Regulations are a part. 2. No curtains, blinds, shades, screens, or signs other than those furnished by Landlord shall be attached to, hung in, or used in connection with any window or door of the Premises without the prior written consent of the Landlord. Interior signs on doors shall be painted or affixed for Tenant by Landlord or by sign painters first approved by Landlord, at the expense of Tenant, and shall be of a size, color and style acceptable to Landlord. 3. No additional locks or bolts of any kind shall be placed upon any of the doors or windows by Tenant, nor shall any changes be made in existing locks or the mechanism thereof without the prior written consent of Landlord. Tenant must, upon the termination of its tenancy, restore to Landlord all keys of stores, shops, booths, stands, offices and toilet rooms, either furnished to or otherwise procured by Tenant; and in the event of the loss of any keys so furnished, Tenant shall pay to Landlord the cost thereof. 4. Canvassing, soliciting and peddling in the Building are prohibited, and Tenant shall cooperate to prevent the same. 5. Tenant may request heating and/or air conditioning during other periods in addition to normal working hours by submitting their request in writing to the Building Manager's office no later than 2:00 PM the preceding workday (Monday through Friday) on forms available from the Building Manager. The request shall clearly state the start and stop hours of the "off-hour" service. Tenant shall submit to the Building Manager a list of personnel who are authorized to make such requests. Charges are to be determined by the Building Manager on the additional hours of operations and shall be fair and reasonable and reflect the additional operating costs involved, provided however, that Tenant shall not be charged to the extent another tenant makes the same request prior to Tenant. Currently such charge is $25.00 per hour for the whole Building and $12.50 per Page 1 of 2 35 hour for one-half of the Building and shall not be changed without prior written notice to Tenant. 6. Tenant shall comply with all security measures from time to time reasonably established by Landlord for the Building. 7. Should Tenant's organization have a non-smoking policy presently in effect for their visitors and/or employees or institute such a policy during the term of this Lease and should such policy not prohibit smoking altogether, then Tenant shall set aside a smoking area within the leased premises, properly ventilated and/or with smoke filtration units, so as not to interfere with any fire protection devices, such as smoke detectors, or the quality of air recirculated in the building's HVAC system.

The undersigned acknowledges that the Bank is and will be relying upon the truth, accuracy and completeness of this letter in proceeding with the transaction described above. The undersigned, for the benefit of the bank, their successors and assigns, hereby certifies, represents, warrants, agrees and acknowledges that: 1.

Page 1 of 2 38 6. The term of the Lease has commenced and is presently scheduled to expire on . If there are any rights of extension or renewal under the terms of the Lease, the same have not, as of the date of this letter, been exercised unless specified in paragraph 9 below. 7. The current Monthly Fixed Rent payment is $__________; Monthly Fixed Rent has been paid through ______________________; Tenant's pro rata share of Operating Cost Escalation is _________%. 8. Until such time as the Bank shall become the Landlord, if the undersigned should assert a claim that the Landlord has failed to perform an obligation to the undersigned under the terms of the Lease or otherwise, notice thereof shall promptly be furnished to the Bank at the following address: Teachers Insurance and Annuity Association of America, 000 Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, or at such other address as Landlord may direct by notice to Tenant; and the undersigned agrees that the undersigned will not exercise any rights which the undersigned might otherwise have on account of any such failure until notice thereof has been given to the Bank, and the Bank has had the same opportunity to cure any such failure as the Landlord may have under the terms of the Lease. 9. Each of the statements set forth in Paragraphs 1 through 8 are true, accurate and complete except as follows (state specifically any exception): DATED: ATTEST: By: By: ------------------------------- ------------------------------- Page 2 of 2 39 EXHIBIT "H" TENANT EXTENSION OPTION Provided that Tenant is not then in default after the giving of any required notice and beyond any applicable cure period under this Lease, Tenant at its option, by written notice provided to Landlord not less than five months prior to the Expiration Date, may elect to extend the term of this Lease for one additional three year term. Unless Tenant withdraws its exercise of this extension option as provided in the following paragraph the exercise of such extension option shall automatically extend the term of this Lease without the necessity of additional documentation, and the term "Expiration Date" shall thenceforth mean the final date of the Lease so extended. At the request of either Landlord or Tenant, however, any such extension shall be memorialized by execution of an amendment which confirms and memorializes such extension. The Fixed Rent payable by Tenant during such extended term shall be at a rate equal to the greater of: (i) 90% of the "Fair Market Rental Value" of the Premises at the time of extension; or (ii) an annual amount equal to $14.85 per square foot, plus a charge for tenant electricity currently estimated at $0.75 per square foot. Within 10 days after said extension notice from Tenant, Landlord shall, after discussion with Tenant, determine the Fair Market Rental Value for the Extension Period by written notice to Tenant. The "Fair Market Rental Value" of the Premises shall mean the fair market rental value of comparable first-class office space in Natick and Framingham, Massachusetts. Ninety percent (90%) of the Fair Market Rental Value so determined by Landlord shall be the Fixed Rent for the extended term, unless Tenant notifies Landlord, within 15 days of Tenant's receipt of Landlord's proposed Fair Market Rental Value, that Landlord's proposed 90% Fair Market Rental Value is not satisfactory to Tenant (such notice being referred to as "Tenant's Rejection Notice"). In the event that Tenant provides a Tenant Rejection Notice, if the Fair Market Rental Value is not otherwise agreed upon by Landlord and Tenant within 15 days after Landlord's receipt of such Tenant Rejection Notice, then Tenant shall be deemed to have withdrawn its exercise of this Extension Option, in which case Tenant's rights under this Extension Option shall terminate, unless Tenant shall give notice to Landlord within 10 days after said 15 day period that Tenant desires to determine the Fair Market Rental Value of the Premises by the following arbitration procedure. In such event, each party shall designate one arbitrator, and the two arbitrators shall designate a third, and the Fair Market Rental Value of the Premises shall be the average of the two closest values determined by three arbitrators (unless the highest and lowest values determined are equidistant from the middle value, in which case the Fair Market Rental Value shall be equal to the middle value). The Fixed Rent for the extension term shall be the greater of: (i) 90% of the Fair Market Rental Value so determined, or (ii) an annual amount equal to $14.85 per square foot plus a charge for tenant electricity currently estimated at $0.75 per square foot. Such determination Page 1 of 1 40 shall, if at all possible, be made within 30 days after Landlord's receipt of Tenant's notification that it desires the Fair Rental Value to be determined by arbitration. Tenant and Landlord shall each pay the fees of any arbitrator appointed by it and shall share equally the fees of the third arbitrator. 41 EXHIBIT "I" RIGHT OF FIRST OFFER ADJACENT SECOND FLOOR SPACE Provided that Tenant is not then in default of this Lease after the giving of any required notice and beyond any applicable cure period and, if within the last eight (8) months of the Term, have exercised its Extension Option as set forth in Exhibit "H" hereof, at the time such Right of First Offer is exercised, Tenant shall be granted a right of first offer to expand into and lease the adjacent first floor space of 6,599 square feet, the current lease for which is scheduled to terminate on April 30, 1997. Landlord will give Tenant notice of the expected date on which said adjacent space will become available promptly after it becomes aware of the same and, in any event, within 14 days of Landlord's notification of its expected availability or within 60 days of the scheduled termination date. Rent for such space shall be fair market value of such space, but not less than Tenant's then existing rent. Landlord shall state its estimation of the fair market value and supporting data in its notification to Tenant. Upon receipt of Landlord's notice of the availability of space and offer to rent it at Landlord's stated fair market rental value, Tenant shall have seven business days to either: (i) accept Landlord's proposed rental terms; or (ii) alternately, within seven business days of receipt of Landlord's notice and offer, to propose an alternate rent for the adjacent space; or (iii) reject Landlord's offer without counter-proposing an alternate rent. Landlord shall have seven business days after receipt of Tenant's counter-proposal of Fixed Rent, if any, to accept or reject Tenant's counter-proposal. In the event of either (i) or (ii) if either Landlord or Tenant accepts the others proposed Fixed Rent, then Landlord shall present Tenant with a lease amendment in reasonable form reflecting such agreement, within ten days of either such acceptance, and Tenant shall have 30 days in which to execute such lease amendment. In such event, failure to execute such lease amendment by Tenant shall result in extinguishment of this right of first offer, and thereafter Landlord shall be free to lease the adjacent space on whatever terms and conditions it desires to any tenant it chooses. In the event of (iii) or failure by Tenant to respond within seven business days, this Right of First Offer shall be extinguished and Landlord shall thereafter be free to lease such space on whatever terms and conditions to whomever it chooses. In the event that Tenant makes a Fixed Rent counter-proposal for said expansion space as set forth in (ii) above, and Landlord rejects such Tenant rent counter-proposal, then Landlord shall be free to rent such adjacent space to any other party at a rent which is greater than Tenant's counter-proposed Fixed Rent (giving due regard to the value of any tenant improvements to be provided by Landlord, rental concessions or other consideration). However, in the event of an offer by a prospective tenant to lease any said adjacent second floor space at a Fixed Rent equal Page 1 of 2 42 to or less than that of Tenant's counter-proposal Fixed Rent (giving due regard to the value of any tenant improvements to be provided by Landlord, rental concessions or other consideration), then Landlord shall give Tenant notice of such a prospective tenant, and Tenant shall have a right of first refusal to lease such adjacent second floor space on identical terms and conditions to that offered such alternate tenant, such right to be exercised by notice given to Landlord within seven days of receipt by Tenant of Landlord's notice of another prospective tenant at such equal or lesser Fixed Rent, and to execute a lease amendment for such adjacent space on such terms and conditions and in reasonable form, within 30 days of acceptance by Tenant of said alternate terms and conditions. Failure by Tenant to execute said lease amendment shall result in an extinguishment of all tenant's rights under this right of first offer, and Landlord shall thereafter be free to lease space as it pleases on whatever terms and conditions to any tenant it chooses. Any such expansion space will be leased in "as is" condition at the date the prospective tenant would have occupied, or one week after such space is vacated by the prior tenant at Tenant's election. The Lease Amendment for such space shall be on the same terms as are set forth herein except: (1) the term shall expire on the Term Expiration Date of this extended Lease; (2) the Fixed Rent for the Expansion Space shall be as set forth above; (3) there shall be no additional Tenant Improvements to the Expanded Premises provided by Landlord; and (4) there shall be no partial rental abatement for the expanded Premises, provided however, that Tenant shall be given credit for the value of any tenant improvements to be provided by Landlord, rental concessions or other consideration which Landlord was to have provided to such other prospective tenant.

("Tenant"). W I T N E S S E T H: WHEREAS, Natick Executive Park Trust No. 2 ("Landlord") and Tenant have entered into a certain lease dated August, 1994, ("Lease") at Building Two, Natick Executive Park, Natick, Massachusetts ("Premises"), said Premises being more particularly described in said Lease and being situated on a portion of the real property described in Exhibit "A" attached hereto and made a part hereof; and WHEREAS, Mortgagee has made a mortgage loan to Landlord in the original principal amount secured by a Mortgage dated _________________ ("Mortgage") covering the Premises, which Mortgage is recorded in official Records Book __, Page ___, of the Middlesex South District Registry of Deeds, Massachusetts. NOW THEREFORE, it is mutually agreed as follows: 1. The Lease is and shall be subject and subordinate to the Mortgage and to all renewals, modifications, consolidations, replacements and extensions of the Mortgage. 2. In the event of a foreclosure of the Mortgage or should Mortgagee obtain title by deed in lieu thereof, or otherwise, Mortgagee, for itself, its successors or assigns, agrees that Tenant may continue its occupancy of the Premises in accordance with the terms and provisions of the Lease, so long as Tenant continues to pay rent and otherwise to perform its obligations thereunder after the giving of any required notice and the expiration of any applicable grace period. Mortgagee agrees not to name Tenant as a party defendant in any foreclosure action. 3. Tenant agrees to attorn to: (a) Mortgagee when in possession of the Premises; (b) a receiver appointed in an action or proceeding to foreclose the Mortgage or otherwise; or (c) to any party acquiring title to the Premises as a result of foreclosure of the Mortgage or deed in lieu thereof. Tenant further covenants and agrees to execute and deliver, upon request of Mortgagee, or its assigns, an appropriate agreement of attornment with any subsequent title holder of the Premises. Page 1 of 3 44 4. So long as the Mortgage on the Premises remains outstanding and unsatisfied, Tenant will deliver to Mortgagee a copy of all notices permitted or required to be given to Landlord by Tenant pursuant to which the Tenant proposes to xxxxx or reduce the rental payable under the Lease or to terminate or cancel the Lease, and that no such notices to Landlord shall be effective, unless a copy of such notice is also delivered to Mortgagee. At any time before the rights of Landlord shall have been forfeited or adversely affected because of any default or failure of performance under the Lease as therein provided, Mortgagee shall have the right (but not the obligation) to cure such default or failure of performance within thirty (30) days from Mortgagee's receipt of such written notice from Tenant stating the nature of such default or failure of performance. 5. Tenant certifies that the Lease has been duly executed by Tenant, that no rent under the Lease has been paid more than thirty (30) days in advance of its due date; and the Tenant, as of this date, has no charge, lien or claim offset under the Lease, or otherwise, against the rents or other charges due or be become due thereunder. 6. If Mortgagee shall succeed to the interest of Landlord under the Lease, Mortgagee shall be bound to Tenant under all the terms, covenants and conditions of the Lease, and Tenant shall, from and after Mortgagee's succession to the interest of Landlord under the Lease, have the same remedies against Mortgagee for the breach of an agreement contained in the Lease that Tenant might have had under the Lease against Landlord if Mortgagee had not succeeded to the interest of Landlord; provided further, however, that Mortgagee shall not be: (a) liable for any warranty, act or omission of any prior landlord, or obligation arising prior to the date of acquisition; (b) subject to any offsets or defense which Tenant might have against any prior landlord (including Landlord), except those which arose out of such Landlord's default under the Lease and which continue after Tenant has notified Mortgagee and given Mortgagee an opportunity to cure as provided herein; and (c) bound by any rent or additional rent which Tenant might have paid more than thirty (30) days in advance to any prior landlord (including Landlord); or (d) bound by any amendment or modification of the Lease or any collateral agreement made without Mortgagee's consent.
