DESCRIPTION OF DEMISED PREMISES<\/p>\n<p>     2.1  DEMISED PREMISES. The Premises are that portion of the Building as<br \/>\ndescribed in Exhibit 1 and is hereinafter referred to as &#8220;Building&#8221;,<br \/>\nsubstantially as shown hatched or outlined on the Lease Plan (Exhibit 2) hereto<br \/>\nattached and incorporated by reference as a part hereof.<\/p>\n<p>     2.2  APPURTENANT RIGHTS. Tenant shall have, as appurtenant to the Premises,<br \/>\nrights to use in common, with others entitled thereto, subject to reasonable<br \/>\nrules from time to time made by Landlord of which Tenant is given notice; (a)<br \/>\nthe common lobbies, hallways, stairways and elevators of the Building, serving<br \/>\nthe Premises in common with others, (b) common walkways necessary for access to<br \/>\nthe Building, and (c) if the Premises include less than the entire rentable area<br \/>\nof any floor, the common toilets and other common facilities of such floor; and<br \/>\nno other appurtenant rights or easements. Landlord shall allow Tenant&#8217;s<br \/>\ntelecommunication service provider to have access to the Building and to<br \/>\nTenant&#8217;s Premises, provided however, that Landlord shall have the right to<br \/>\ncharge Tenant&#8217;s provider fees in connection with the services being performed by<br \/>\nsuch provider. Notwithstanding the foregoing, so long as Tenant&#8217;s<br \/>\ntelecommunications service provider (&#8220;Provider&#8221;) does not provide<br \/>\ntelecommunications service to any other tenant of the Building, Landlord shall<br \/>\nnot require such Provider to pay any fees for such access.<\/p>\n<p>     2.3  PARKING. During the term of the Lease, commencing on the Rent<br \/>\nCommencement Date (and, if there is more than one Rent Commencement Date<br \/>\npursuant to Article 3.1 hereof commencing on a pro rata basis with each such<br \/>\nRent Commencement Date), the Landlord will make available, at Tenant&#8217;s written<br \/>\nrequest, which request must be made on or before the Full Rent Commencement<br \/>\nDate, up to one and one-half (1.5) monthly parking passes per 1,000 square feet<br \/>\nof Total Rentable Area leased by Tenant (the &#8220;Parking Space Cap&#8221;) for use in the<br \/>\ngarage of the Complex or surface parking areas in the Building, as the same may<br \/>\nchange from time to time (&#8220;Parking Areas&#8221;). If Tenant fails timely to make such<br \/>\nrequest for any such parking passes, Tenant shall have no right to obtain such<br \/>\nparking passes under this Article 2.3, except to the extent thereafter<br \/>\navailable, as more specifically set forth herein. If Tenant requests fewer<br \/>\npasses than the Parking Space Cap prior to the Full Rent Commencement Date,<br \/>\nTenant shall have the right, from time to time during the term of the Lease, to<br \/>\nrequest additional parking passes up to the Parking Space Cap. If Landlord has<br \/>\nsuch passes available, Landlord will provide the same to Tenant (but in no event<br \/>\nmore than the Parking Space Cap), provided<\/p>\n<p>                                      -1-<br \/>\n   10<\/p>\n<p>however, that, if such passes are not available, Landlord shall have no<br \/>\nobligation to provide additional passes to Tenant. Tenant shall have no right to<br \/>\nsublet, assign, or otherwise transfer said parking passes, other than to an<br \/>\nAssignee or a Qualified Transferee pursuant to an approved assignment or<br \/>\nsublease under Article 16 of the Lease. Said parking passes shall be paid for by<br \/>\nTenant at the then current prevailing rate in the Parking Areas, as such rate<br \/>\nmay vary from time to time. If, for any reason, Tenant shall fail timely to pay<br \/>\nthe charge for said parking passes, and if such default continues for ten (10)<br \/>\ndays after written notice, Tenant shall have no further right to the parking<br \/>\npasses for which Tenant failed to pay the charge under this Article 2.3. Said<br \/>\nparking passes will be on an unassigned, non-reserved basis, and shall be<br \/>\nsubject to such reasonable and uniform rules and regulations as may be in effect<br \/>\nfor the use of said Parking Areas (including, without limitation, Landlord&#8217;s<br \/>\nright, without additional charge to Tenant above the prevailing rate for parking<br \/>\npasses, to institute a valet or attendant-managed parking system), from time to<br \/>\ntime in force.<\/p>\n<p>     2.4  EXCLUSIONS AND RESERVATIONS.

Any floor shall be deemed to be &#8220;Building Tight&#8221; if<br \/>\nall of the following have been achieved:<\/p>\n<p>          i.)       The roof of the Building has been installed and is<br \/>\n                    weather-tight;<br \/>\n          ii.)      The windows on such floor have been installed and are<br \/>\n                    weather-tight;<br \/>\n          iii.)     The precast concrete on such floor has been installed and<br \/>\n                    is weather-tight;<br \/>\n          iv.)      All core walls facing the tenanted areas of such floor have<br \/>\n                    been substantially completed;<br \/>\n          v.)       The perimeter wall of the Building on such floor has been<br \/>\n                    installed, is weather tight and has interior drywall ready<br \/>\n                    for finish treatment;<br \/>\n          vi.)      Temporary power is available to Tenant on such floor;<br \/>\n          vii.)     All base building mechanical systems which are to be<br \/>\n                    provided to such floor have been stubbed to such floor.<\/p>\n<p>     (l)  CERTIFICATE OF OCCUPANCY TEST.<\/p>\n<p>          i.)  As a Condition to the Base Building Substantial Completion Date.<br \/>\nReference is made to clauses (g) and (j) of Article 4.0(j)(iv), which provide<br \/>\nthat, as a condition to achieving the Base Building Substantial Completion Date,<br \/>\nLandlord&#8217;s Work must have been completed to the extent necessary to enable<br \/>\nTenant to obtain a Certificate of Occupancy for the Premises (hereinafter<br \/>\nreferred to as the &#8220;Certificate of Occupancy Test&#8221;). Landlord shall apply to the<br \/>\nBuilding Inspector of the City of Cambridge (&#8220;Building Inspector&#8221;) for a<br \/>\nCertificate of Occupancy with respect to Landlord&#8217;s Work (&#8220;Base Building&#8221;) in<br \/>\norder to assist the parties in determining whether the Base Building Substantial<br \/>\nCompletion Date has occurred. If the Building Inspector issues a Base Building<br \/>\nCertificate of Occupancy, the Certificate of Occupancy Test shall be<br \/>\nconclusively deemed to have been satisfied. The parties acknowledge that: (a) if<br \/>\nTenant&#8217;s Work has not progressed to the point where Tenant is able to apply for<br \/>\na Certificate of Occupancy with respect to at least a portion of the Premises,<br \/>\nthe Building Inspector may not be willing to perform such inspection, (b) given<br \/>\nthat Tenant&#8217;s Work includes a portion of the sprinkler system, the Building<br \/>\nInspector may not be able to issue a Base Building Certificate of Occupancy if<br \/>\nTenant&#8217;s Work is not complete, and (c) other incomplete portions of Tenant&#8217;s<br \/>\nWork may prevent Landlord from obtaining a Base Building Certificate of<br \/>\nOccupancy. If the Building Inspector is willing to perform such inspection and<br \/>\nif the Building Inspector denies the issuance of the Base Building Certificate<br \/>\nof Occupancy based solely on deficiencies identified by the Building Inspector<br \/>\nin Landlord&#8217;s Work, then the Certificate of Occupancy Test shall not be deemed<br \/>\nsatisfied until Landlord corrects such deficiencies to the satisfaction of the<br \/>\nBuilding Inspector. If, despite Landlord&#8217;s application for a Base Building<br \/>\nCertificate of Occupancy, the Building Inspector does not perform such<br \/>\ninspection, or if the Building Inspector performs such inspection, but does not<br \/>\nidentify any deficiencies in Landlord&#8217;s Work and does not issue a Base Building<br \/>\nCertificate of Occupancy, then the Certificate of Occupancy Test may still be<br \/>\nsatisfied as follows: Landlord shall notify Tenant when it believes that all of<br \/>\nLandlord&#8217;s Work necessary for Tenant to obtain a Certificate of Occupancy has<br \/>\nbeen substantially completed (&#8220;Landlord&#8217;s Completion Notice&#8221;). If Tenant<br \/>\ndisputes Landlord&#8217;s assertion of substantial<\/p>\n<p>                                      -7-<br \/>\n   16<\/p>\n<p>completion, it shall so notify Landlord within ten (10) days after receipt of<br \/>\nLandlord&#8217;s Completion Notice, whereupon such dispute shall be immediately<br \/>\nsubmitted to arbitration in accordance with the provisions of Article 29.5. The<br \/>\nparties hereby acknowledge that Tenant, and not Landlord, is responsible for all<br \/>\nitems of Tenant&#8217;s Work which must be completed in order to enable Tenant to<br \/>\nobtain a Certificate of Occupancy for the Premises and in no event shall<br \/>\nLandlord be deemed to have failed to satisfy the Certificate of Occupancy Test<br \/>\nbased upon any deficiency or lack of completion of Tenant&#8217;s Work.<\/p>\n<p>          ii.) Tenant&#8217;s Inability to Obtain a Certificate of Occupancy after the<br \/>\nOccurrence of the Base Building Substantial Completion Date. If the Base<br \/>\nBuilding Substantial Completion Date (i.e. and the Rent Commencement Date)<br \/>\noccurs prior to the issuance of a Certificate of Occupancy with respect to any<br \/>\nportion of the Premises, and if, subsequently Tenant is denied a Certificate of<br \/>\nOccupancy with respect to any portion of the Premises, solely by reason of any<br \/>\ndeficiency in Landlord&#8217;s Work, then: (x) Landlord shall, as promptly as<br \/>\npossible, remedy such deficiency so as to remove such impediment to Tenant&#8217;s<br \/>\nobtaining such Certificate of Occupancy, and (y) Tenant&#8217;s obligation to pay<br \/>\nYearly Rent and other charges due under the Lease in respect of the portion of<br \/>\nthe Premises which Tenant is unable to occupy because it cannot obtain such<br \/>\nCertificate of Occupancy shall be fully abated during the period of time<br \/>\ncommencing as of the date that Tenant is denied such Certificate of Occupancy<br \/>\nuntil Landlord cures such deficiency in Landlord&#8217;s Work so that it is no longer<br \/>\nprevents Tenant from obtaining such Certificate of Occupancy.<\/p>\n<p>     (m)  TENANT DELAY. A &#8220;Tenant Delay&#8221; shall be defined as any act or omission<br \/>\nby Tenant, or any agent, employee, consultant, contractor, or subcontractor of<br \/>\nTenant, which causes an actual delay in the performance of Landlord&#8217;s Work<br \/>\nNecessary to Trigger Full Rent Commencement Date. Notwithstanding the foregoing,<br \/>\nno event shall be deemed to be a Tenant Delay until and unless Landlord has<br \/>\ngiven Tenant written notice (&#8220;Tenant Delay Notice&#8221;) advising Tenant: (i) that a<br \/>\nTenant Delay is occurring, (ii) of the basis on which Landlord has determined<br \/>\nthat a Tenant Delay is occurring, and (iii) the actions which Landlord believes<br \/>\nthat Tenant must take to eliminate such Tenant Delay. No period of time prior to<br \/>\nthe time that Tenant receives a Tenant Delay Notice shall be included in the<br \/>\nperiod of time charged to Tenant pursuant to such Tenant Delay Notice.<\/p>\n<p>     (n)  LANDLORD DELAY. A &#8220;Landlord Delay&#8221; shall be defined as any act or<br \/>\nomission by Landlord or any agent, employee, consultant, contractor or<br \/>\nsubcontractor of Landlord which: (i) is not a result of the priority granted to<br \/>\nLandlord&#8217;s Work as set forth in Article 4.2(c) hereof, and (ii) causes an actual<br \/>\ndelay in the performance of Tenant&#8217;s Work. Notwithstanding the foregoing, except<br \/>\nas set forth in Article 4.2(e), no event shall be deemed to be a Landlord Delay<br \/>\nuntil and unless Tenant has given Landlord written notice (&#8220;Landlord Delay<br \/>\nNotice&#8221;) advising Landlord: (i) that a Landlord Delay is occurring, (ii) of the<br \/>\nbasis on which Tenant has determined that a Landlord Delay is occurring, and<br \/>\n(iii) the actions which Tenant believes that Landlord must take to eliminate<br \/>\nsuch Landlord Delay. No period of time prior to the time that Landlord receives<br \/>\na Landlord Delay Notice shall be included in the period of time charged to<br \/>\nLandlord pursuant to such Landlord Delay Notice.<\/p>\n<p>     (o)  LANDLORD&#8217;S WARRANTY; SATISFACTION OF LANDLORD&#8217;S OBLIGATIONS UNDER<br \/>\nARTICLE 4.<\/p>\n<p>                                      -8-<br \/>\n   17<\/p>\n<p>     i.)  Landlord&#8217;s Warranty. Landlord warrants to Tenant that: (x) materials<br \/>\nand equipment furnished in the performance of Landlord&#8217;s Work will be of good<br \/>\nquality and new unless otherwise required or permitted by the Base Building<br \/>\nSpecifications, (y) Landlord&#8217;s Work will be free from defects not inherent in<br \/>\nthe quality required or permitted under the Base Building Specifications, and<br \/>\n(z) Landlord&#8217;s Work will conform the requirements of the Base Building<br \/>\nSpecifications. Any portion of Landlord&#8217;s Work not conforming to the<br \/>\nrequirements of this clause (i), including substitutions not properly approved<br \/>\nand authorized, may be considered defective. Landlord&#8217;s warranty excludes remedy<br \/>\nfor damage or defect caused by abuse, modifications not executed by Landlord,<br \/>\nimproper or insufficient maintenance (other than by Landlord, where Landlord is<br \/>\nrequired to perform maintenance on the item or system in question), improper<br \/>\noperation (other than by Landlord, where Landlord operates the item or system in<br \/>\nquestion), or normal wear and tear and normal usage.<\/p>\n<p>     ii.) Warranty Period. Landlord shall be deemed to have satisfied all of its<br \/>\nobligations under this Article 4 (including, without limitation, Landlord&#8217;s<br \/>\nwarranty obligations under this Article 4.0(o) and under Article 4.3) except to<br \/>\nthe extent that, on or before the Warranty Expiration Date, as hereinafter<br \/>\ndefined, Tenant gives written notice to Landlord in accordance with the<br \/>\nprovisions of Article 27 setting forth with specificity the manner in which<br \/>\nTenant believes that Landlord has failed to comply with its obligations under<br \/>\nthis Article 4. The &#8220;Warranty Expiration Date&#8221; shall be defined as the date<br \/>\nthree hundred fifty-eight (358) days after the Full Rent Commencement Date.<\/p>\n<p>     iii.) Repair of Defective Work. Landlord agrees that it shall, without cost<br \/>\nto Tenant, correct any portion of Landlord&#8217;s Work which is found not to be in<br \/>\naccordance with the requirements of the warranties set forth in this Article<br \/>\n4.0(o) and in Article 4.3, unless Tenant has previously given Landlord a written<br \/>\nacceptance of such condition, provided that: Tenant gives Landlord written<br \/>\nnotice of such condition in accordance with the provisions of Article 27<br \/>\npromptly after it becomes aware of such condition, and in any event on or before<br \/>\nthe Warranty Expiration Date. The provisions of this Article 4.0(o) shall not<br \/>\nrelieve Landlord of any obligation which Landlord has to make repairs or to<br \/>\nperform maintenance pursuant to Article 8 of the Lease.<\/p>\n<p>     (p)  Any dispute between the parties with respect to the provisions of this<br \/>\nArticle 4 shall be submitted to arbitration in accordance with Article 29.5.<\/p>\n<p>     4.1  TENANT&#8217;S REMEDIES BASED ON DELAYS IN LANDLORD&#8217;S WORK.<\/p>\n<p>     (a)  If the Term Commencement Date shall not have occurred on or before<br \/>\nOctober 1, 2001 (&#8220;INITIAL OUTSIDE COMPLETION DATE&#8221;) (which date shall be<br \/>\nextended for up to ninety (90) days on account of any Force Majeure Delays, as<br \/>\nhereinafter defined), Tenant shall have the right to terminate this Lease by<br \/>\ngiving notice to Landlord of Tenant&#8217;s desire to do so before such completion and<br \/>\nwithin the time period from the Initial Outside Completion Date (as so extended)<br \/>\nuntil the date which is thirty (30) days subsequent to the Initial Outside<br \/>\nCompletion Date (as so extended); and, upon the giving of such notice, the Term<br \/>\nof this Lease shall cease and come to an end without further liability or<br \/>\nobligation on the part of either party unless, within thirty (30) days after<br \/>\nreceipt of such notice, the Term Commencement Date occurs.

In the event that the costs<br \/>\n     of a Complex amenity are included in an Operating Year but such costs were<br \/>\n     not included in the Complex Operating Costs Base, then the Complex<br \/>\n     Operating Costs Base shall be adjusted to reflect what would have been the<br \/>\n     costs for such amenity in the Complex Operating Costs Base if such amenity<br \/>\n     had been operated during calendar year 2000.<\/p>\n<p>     9.2  TAX EXCESS.<\/p>\n<p>          (a)  IN GENERAL. Commencing as of the Rent Commencement Date (or, if<br \/>\nthere is more than one Rent Commencement Date hereunder, the first such date),<br \/>\nand continuing thereafter throughout the term of this Lease, if with respect to<br \/>\nany Tax Period, the sum (&#8220;Tenant&#8217;s Tax Share&#8221;) of (i) Tenant&#8217;s Building Tax<br \/>\nPercentage of Building Taxes plus (ii) Tenant&#8217;s Complex Tax Percentage of Land<br \/>\nTaxes exceeds the Tax Base, Tenant shall, subject to Article 9.10, pay such<br \/>\nexcess to Landlord, such amount being hereinafter referred to as &#8220;Tax Excess.&#8221;<br \/>\nTax Excess shall be due within thirty (30) days of Tenant&#8217;s receipt of<br \/>\nLandlord&#8217;s bill therefor. In implementation and not in limitation of the<br \/>\nforegoing, Tenant shall remit to Landlord pro rata monthly installments on<br \/>\naccount of projected Tax Excess, calculated by Landlord on the basis of the most<br \/>\nrecent Tax data available. If the total of such monthly remittances on account<br \/>\nof any Tax Period is greater than the actual Tax Excess for such Tax Period,<br \/>\nTenant may credit the difference against the next installment of rental or other<br \/>\ncharges due to Landlord hereunder, except that if such difference is determined<br \/>\nafter the end of the term of this Lease, Landlord shall refund such difference<br \/>\nto Tenant within thirty (30) days after such determination to the extent that<br \/>\nsuch difference exceeds any amounts then due from Tenant to Landlord. If the<br \/>\ntotal of such remittances is less than the actual Tax Excess for such Tax<br \/>\nPeriod, Tenant shall pay the difference to Landlord within thirty (30) days of<br \/>\nTenant&#8217;s receipt of the bill.<\/p>\n<p>          (b)  EFFECT OF ABATEMENTS. Appropriate credit against Tax Excess shall<br \/>\nbe given for any refund obtained by reason of a reduction in any Taxes by the<br \/>\nAssessors or the administrative, judicial or other governmental agency<br \/>\nresponsible therefor. The original computations, as well as reimbursement or<br \/>\npayments of additional charges, if any, or allowances, if any, under the<br \/>\nprovisions of this Article 9.2 shall be based on the original assessed<br \/>\nvaluations<\/p>\n<p>                                      -29-<br \/>\n   38<\/p>\n<p>with adjustments to be made at a later date when the tax refund, if any, shall<br \/>\nbe paid to Landlord by the taxing authorities. Expenditures for reasonable legal<br \/>\nfees and for other reasonable similar or dissimilar expenses incurred in<br \/>\nobtaining the tax refund may be charged against the tax refund before the<br \/>\nadjustments are made for the Tax Period.<\/p>\n<p>     9.3  OPERATING EXPENSE EXCESS.<\/p>\n<p>     Commencing as of the Rent Commencement Date (or, if there is more than one<br \/>\nRent Commencement Date hereunder, the first such date), and continuing<br \/>\nthereafter throughout the term of the Lease, if with respect to any Operating<br \/>\nYear, the Building Operating Costs exceed the Operating Cost Base, Tenant shall,<br \/>\nsubject to Article 9.10, pay Tenant&#8217;s Building Operating Cost Percentage of such<br \/>\nexcess to Landlord, such amount being hereinafter referred to as &#8220;Operating<br \/>\nExpense Excess.&#8221; Operating Expense Excess shall be due within thirty (30) days<br \/>\nof the Tenant&#8217;s receipt of the Landlord&#8217;s bill therefor. In implementation and<br \/>\nnot in limitation of the foregoing, Tenant shall remit to Landlord pro rata<br \/>\nmonthly installments on account of projected Operating Expense Excess,<br \/>\ncalculated by Landlord on the basis of the most recent Operating Costs data or<br \/>\nbudget available. Landlord shall, within one hundred twenty (120) days after the<br \/>\nend of each Operating Year, deliver to Tenant a reasonably detailed statement<br \/>\n(&#8220;Year End Statement&#8221;) of the actual amount of Operating Costs for such<br \/>\nOperating Year. If the total of such monthly remittances on account of any<br \/>\nOperating Year is greater than the actual Operating Expense Excess for such<br \/>\nOperating Year, Tenant may credit the difference against the next installment of<br \/>\nrent or other charges due to Landlord hereunder, except that if such difference<br \/>\nis determined after the end of the term of this Lease, Landlord shall refund<br \/>\nsuch difference to Tenant within thirty (30) days after such determination to<br \/>\nthe extent that such difference exceeds any amounts then due from Tenant to<br \/>\nLandlord. If the total of such remittances is less than actual Operating Expense<br \/>\nExcess for such Operating Year, Tenant shall pay the difference to Landlord<br \/>\nwithin thirty (30) days of Tenant&#8217;s receipt of Landlord&#8217;s bill therefor.<\/p>\n<p>     9.4  PART YEARS. If any Rent Commencement Date or if the Termination Date<br \/>\noccurs in the middle of an Operating Year or Tax Period, Tenant shall be liable<br \/>\nfor only that portion of the Operating Expense or Tax Excess, as the case may<br \/>\nbe, in respect of such Operating Year or Tax Period represented by a fraction<br \/>\nthe numerator of which is the number of days of the herein term (commencing as<br \/>\nof the applicable Rent Commencement Date) which falls within the Operating Year<br \/>\nor Tax Period and the denominator of which is three hundred sixty-five (365), or<br \/>\nthe number of days in said Tax Period, as the case may be. Any credit pursuant<br \/>\nto Article 9.10 for the years in which any Rent Commencement Date or the<br \/>\nTermination Date occur shall be similarly pro-rated.<\/p>\n<p>     9.5  EFFECT OF TAKING. In the event of any taking of a portion of the<br \/>\nComplex, the Building or the land upon which it stands under circumstances<br \/>\nwhereby this Lease shall not terminate under the provisions of Article 20 then,<br \/>\nfor the purposes of determining Tax Excess, there shall be substituted for the<br \/>\nTax Base originally provided for herein a fraction of such Tax Base, the<br \/>\nnumerator of which fraction shall be the Taxes for the first Tax Period<br \/>\nsubsequent to the condemnation or taking which takes into account such<br \/>\ncondemnation or taking, and the denominator of which shall be the Taxes for the<br \/>\nlast Tax Period prior to the condemnation or taking, which did not take into<br \/>\naccount such condemnation or taking. Tenant&#8217;s Building Tax Percentage shall be<br \/>\nadjusted appropriately to reflect the proportion of the Premises and the<br \/>\nBuilding remaining after such taking.<\/p>\n<p>                                      -30-<br \/>\n   39<\/p>\n<p>     9.6  ADJUSTMENT OF OPERATING COSTS BASED UPON OCCUPANCY. If less than<br \/>\nninety-five percent (95%) of the rentable area of the Building shall have been<br \/>\noccupied by tenants at any time during any Operating Year (including the Base<br \/>\nYear), or if services, for any other reason, are not provided by Landlord to at<br \/>\nleast ninety-five (95%) percent of the rentable area of the Building, then, at<br \/>\nLandlord&#8217;s election, Building Operating Costs for such Operating Year shall be<br \/>\nadjusted to equal the amount which Landlord reasonably determines is the amount<br \/>\nBuilding Operating Costs would have been for such period had occupancy been<br \/>\nninety-five percent (95%) throughout such period, or if such services had been<br \/>\nprovided to ninety-five (95%) percent of the Building throughout such period, as<br \/>\nthe case may be.<\/p>\n<p>     9.7  EFFECT OF CONVERSION OF COMPLEX TO A CONDOMINIUM. Landlord reserves<br \/>\nthe right to create a condominium encompassing some or all of the Complex,<br \/>\nincluding the Building. In the event that such a condominium is created, then<br \/>\n(i) if the Building shall constitute a separately assessed unit in the<br \/>\ncondominium, Building Taxes shall thereafter be defined as the amount of Taxes<br \/>\nassessed against such unit, and if the Building does not constitute a separately<br \/>\nassessed unit, Landlord shall thereafter equitably allocate Taxes to the<br \/>\nBuilding and the Land on a reasonable basis; and (ii) Landlord shall include any<br \/>\ncondominium fees assessed against the unit containing the premises in Building<br \/>\nOperating Costs and Complex Operating Costs, as the case may be, to the extent<br \/>\nsuch fees represent costs which would otherwise be included in Building<br \/>\nOperating Costs or Complex Operating Costs. The allocation of any such<br \/>\ncondominium fees between Building Operating Costs and Complex Operating Costs<br \/>\nshall be based on square footage of Total Rentable Area of the premises<br \/>\nbenefiting from the cost in question, unless Landlord reasonably determines that<br \/>\nsuch allocation should be made on another reasonable basis.<\/p>\n<p>     9.8  DISPUTES, ETC. Any disputes arising under this Article 9 may, at the<br \/>\nelection of either party, be submitted to arbitration as hereinafter provided.<br \/>\nAny obligations under this Article 9 which shall not have been paid at the<br \/>\nexpiration or sooner termination of the term of this Lease shall survive such<br \/>\nexpiration and shall be paid when and as the amount of same shall be determined<br \/>\nand be due.<\/p>\n<p>     9.9  TENANT&#8217;S AUDIT RIGHTS. Subject to the provisions of this paragraph,<br \/>\nTenant shall have the right, at Tenant&#8217;s cost and expense, to examine all<br \/>\ndocumentation and calculations prepared in the determination of Operating<br \/>\nExpense Excess:<\/p>\n<p>          1.   Such documentation and calculation shall be made available to<br \/>\n               Tenant at the offices where Landlord keeps such records during<br \/>\n               normal business hours within a reasonable time after Landlord<br \/>\n               receives a written request from Tenant to make such examination.<\/p>\n<p>          2.   Tenant shall have the right to make such examination no more than<br \/>\n               once in respect of any period in which Landlord has given Tenant<br \/>\n               a statement of the actual amount of Operating Costs.<\/p>\n<p>          3.   Any request for examination in respect of any Operating Year may<br \/>\n               be made no more than sixty (60) days after Landlord advises<br \/>\n               Tenant of the actual amount of Operating Costs in respect of such<br \/>\n               period.<\/p>\n<p>          4.   Such examination may be made only by a nationally recognized<br \/>\n               independent certified public accounting firm approved by<br \/>\n               Landlord, such<\/p>\n<p>                                      -31-<br \/>\n   40<\/p>\n<p>               approval not to be unreasonably withheld or delayed. Without<br \/>\n               limiting Landlord&#8217;s approval rights, Landlord may withhold its<br \/>\n               approval of any examiner of Tenant who is being paid by Tenant on<br \/>\n               a contingent fee basis.<\/p>\n<p>          5.   As a condition to performing any such examination, Tenant and its<br \/>\n               examiners shall be required to execute and deliver to Landlord an<br \/>\n               agreement, in form reasonably acceptable to Landlord, agreeing to<br \/>\n               keep confidential any information which it discovers about<br \/>\n               Landlord or the Building or the Complex in connection with such<br \/>\n               examination.<\/p>\n<p>          6.   If such audit reveals an overcharge of more than five percent<br \/>\n               (5%), Landlord shall reimburse Tenant the reasonable cost of such<br \/>\n               audit within thirty (30) days after written demand therefor.<\/p>\n<p>     9.10 CREDIT IF OPERATING COSTS AND TAXES ARE LESS THAN THEIR RESPECTIVE<br \/>\nBASES.<\/p>\n<p>     (a)  The provisions of this Article 9.10(a) shall only apply if, with<br \/>\nrespect to any Operating Year, Tenant is required to pay Operating Expense<br \/>\nExcess, but the amount of Tenant&#8217;s Tax Share for such Operating Year is less<br \/>\nthan the Tax Base. In such instance, the amount of Operating Expense Excess<br \/>\npayable by Tenant for such Operating Year shall be reduced by an amount equal to<br \/>\nthe amount by which the Tax Base exceeds Tenant&#8217;s Tax Share for such Operating<br \/>\nYear. Since, as of the Execution Date, the method for determining Tenant&#8217;s Tax<br \/>\nShare is determined based upon a fiscal Tax Period commencing as of each July 1<br \/>\nand ending as of the following June 30, Tenant&#8217;s Tax Share for any Operating<br \/>\nYear shall, for the purposes of this Article 9.10(a), be determined based upon<br \/>\nthe pro-rata portion of the actual amount of Taxes payable in respect of each<br \/>\nTax Period which overlaps such Operating Year. Following are three examples of<br \/>\nthis calculation:<\/p>\n<p>     EXAMPLE 1<\/p>\n<p>     (1)  For calendar year 2002, the Operating Expense Excess payable by Tenant<br \/>\n     would be $1,000.00, but for the provisions of this Article 9.10(a), and<\/p>\n<p>     (2)  For fiscal year 2002 (i.e. July 1, 2001-June 30, 2002), the Tenant&#8217;s<br \/>\n     Tax Share is $500.00 LESS than the Tax Base, and<\/p>\n<p>     (3)  For fiscal year 2003 (i.e. July 1, 2002-June 30, 2003), the Tenant&#8217;s<br \/>\n     Tax Share is $200.00 MORE than the Tax Base, then,<\/p>\n<p>     (4)  The amount of Operating Expense Excess payable by Tenant for calendar<br \/>\n     year 2002 shall be reduced by $150.00 pursuant to this Article 9.10(a) (the<br \/>\n     reduction amount being equal to 50% of the amount by which Tenant&#8217;s Tax<br \/>\n     Share is LESS than the Tax Base for fiscal year 2002 [$250.00] MINUS 50% of<br \/>\n     the amount by which Tenant&#8217;s Tax Share for fiscal year 2003 is MORE than<br \/>\n     the Tax Base [$100.00]).<\/p>\n<p>     EXAMPLE 2<\/p>\n<p>                                      -32-<br \/>\n   41<\/p>\n<p>     (1)  For calendar year 2002, the Operating Expense Excess payable by Tenant<br \/>\n     would be $1,000.00, but for the provisions of this Article 9.10(a), and<\/p>\n<p>     (2)  For fiscal year 2002 (i.e. July 1, 2001-June 30, 2002), the Tenant&#8217;s<br \/>\n     Tax Share is $400.00 LESS than the Tax Base, and<\/p>\n<p>     (3)  For fiscal year 2003 (i.e. July 1, 2002-June 30, 2003), the Tenant&#8217;s<br \/>\n     Tax Share is $300.00 LESS than the Tax Base, then,<\/p>\n<p>     (4)  The amount of Operating Expense Excess payable by Tenant for calendar<br \/>\n     year 2002 shall be reduced by $350.00 pursuant to this Article 9.10(a) (the<br \/>\n     reduction amount being equal to 50% of the amount by which Tenant&#8217;s Tax<br \/>\n     Share is LESS than the Tax Base for fiscal year 2002 [$200.00] PLUS 50% of<br \/>\n     the amount by which Tenant&#8217;s Tax Share for fiscal year 2003 is LESS than<br \/>\n     the Tax Base [$150.00]).<\/p>\n<p>     EXAMPLE 3<\/p>\n<p>     (1)  For calendar year 2002, the Operating Expense Excess payable by Tenant<br \/>\n     would be $1,000.00, but for the provisions of this Article 9.10(a), and<\/p>\n<p>     (2)  For fiscal year 2002 (i.e. July 1, 2001-June 30, 2002), the Tenant&#8217;s<br \/>\n     Tax Share is $300.00 LESS than the Tax Base, and<\/p>\n<p>     (3)  For fiscal year 2003 (i.e. July 1, 2002-June 30, 2003), the Tenant&#8217;s<br \/>\n     Tax Share is $600.00 MORE than the Tax Base, then,<\/p>\n<p>     (4)  The amount of Operating Expense Excess payable by Tenant for calendar<br \/>\n     year 2002 shall not be reduced pursuant to this Article 9.10(a) (the<br \/>\n     reduction amount being equal to 50% of the amount by which Tenant&#8217;s Tax<br \/>\n     Share is LESS than the Tax Base for fiscal year 2002 [$150.00] MINUS 50% of<br \/>\n     the amount by which Tenant&#8217;s Tax Share for fiscal year 2003 is MORE than<br \/>\n     the Tax Base [$300.00], but never less than zero).<\/p>\n<p>     (b)  The provisions of this Article 9.10(b) shall only apply if, with<br \/>\nrespect to any Tax Period, Tenant is required to pay Tax Excess, but the amount<br \/>\nof Tenant&#8217;s Building Operating Cost Percentage of Building Operating Costs<br \/>\n(&#8220;Tenant&#8217;s Operating Share&#8221;) for such Tax Period is less than the Operating Cost<br \/>\nBase. In such event, the amount of Tax Excess payable by Tenant for such Tax<br \/>\nPeriod shall be reduced by an amount equal to the amount by which the Operating<br \/>\nCost Base exceeds Tenant&#8217;s Operating Share for such Tax Period. Since, as of the<br \/>\nExecution Date, the method for determining Tenant&#8217;s Tax Share is determined<br \/>\nbased upon a fiscal Tax Period commencing as of each July 1 and ending as of the<br \/>\nfollowing June 30, Tenant&#8217;s Operating Share for any Tax Period shall, for the<br \/>\npurposes of this Article 9.10(b), be determined based upon the pro-rata portion<br \/>\nof the actual amount of Tenant&#8217;s Operating Share payable in respect of each<br \/>\nOperating Year which overlaps such Tax Period Year. Following are three examples<br \/>\nof this calculation:<\/p>\n<p>     EXAMPLE 1<\/p>\n<p>     (1)  For fiscal year 2003 (i.e. July 1, 2002-June 30, 2003), the Tax Excess<br \/>\n     payable by Tenant would be $1,000.00, but for the provisions of this<br \/>\n     Article 9.10(b), and<\/p>\n<p>                                      -33-<br \/>\n   42<\/p>\n<p>     (2)  For calendar year 2002, the Tenant&#8217;s Operating Share is $500.00 LESS<br \/>\n     than the Operating Cost Base, and<\/p>\n<p>     (3)  For calendar year 2003, the Tenant&#8217;s Operating Share is $200.00 MORE<br \/>\n     than the Operating Cost Base, then,<\/p>\n<p>     (4)  The amount of Tax Excess payable by Tenant for fiscal year 2003 shall<br \/>\n     be reduced by $150.00 pursuant to this Article 9.10(b) (the reduction<br \/>\n     amount being equal to 50% of the amount by which Tenant&#8217;s Operating Share<br \/>\n     is LESS than the Operating Cost Base for calendar year 2002 [$250.00] MINUS<br \/>\n     50% of the amount by which Tenant&#8217;s Operating Share for calendar year 2003<br \/>\n     is MORE than the Operating Cost Base [$100.00]).<\/p>\n<p>     EXAMPLE 2<\/p>\n<p>     (1)  For fiscal year 2003 (i.e. July 1, 2002-June 30, 2003), the Tax Excess<br \/>\n     payable by Tenant would be $1,000.00, but for the provisions of this<br \/>\n     Article 9.10(b), and<\/p>\n<p>     (2)  For calendar year 2002, the Tenant&#8217;s Operating Share is $400.00 LESS<br \/>\n     than the Operating Cost Base, and<\/p>\n<p>     (3)  For calendar year 2003, the Tenant&#8217;s Operating Share is $300.00 LESS<br \/>\n     than the Operating Cost Base, then,<\/p>\n<p>     (4)  The amount of Tax Excess payable by Tenant for fiscal year 2003 shall<br \/>\n     be reduced by $350.00 pursuant to this Article 9.10(b) (the reduction<br \/>\n     amount being equal to 50% of the amount by which Tenant&#8217;s Operating Share<br \/>\n     is LESS than the Operating Cost Base for calendar year 2002 [$200.00] PLUS<br \/>\n     50% of the amount by which Tenant&#8217;s Operating Share for calendar year 2003<br \/>\n     is LESS than the Operating Cost Base [$150.00]).<\/p>\n<p>     EXAMPLE 3<\/p>\n<p>     (1)  For fiscal year 2003 (i.e. July 1, 2002-June 30, 2003), the Tax Excess<br \/>\n     payable by Tenant would be $1,000.00, but for the provisions of this<br \/>\n     Article 9.10(b), and<\/p>\n<p>     (2)  For calendar year 2002, the Tenant&#8217;s Operating Share is $300.00 LESS<br \/>\n     than the Operating Cost Base, and<\/p>\n<p>     (3)  For calendar year 2003, the Tenant&#8217;s Operating Share is $600.00 MORE<br \/>\n     than the Operating Cost Base, then,<\/p>\n<p>     (4)  The amount of Tax Excess payable by Tenant for fiscal year 2003 shall<br \/>\n     not be reduced pursuant to this Article 9.10(b) (the reduction amount being<br \/>\n     equal to 50% of the amount by which Tenant&#8217;s Operating Share is LESS than<br \/>\n     the Operating Cost Base for calendar year 2002 [$150.00] MINUS 50% of the<br \/>\n     amount by which Tenant&#8217;s Operating Share for calendar year 2003 is MORE<br \/>\n     than the Operating Cost Base [$300.00], but never less than zero).<\/p>\n<p>                                      -34-<br \/>\n   43<\/p>\n<p>10.

CONDEMNATION &#8211; EMINENT DOMAIN<\/p>\n<p>     (a)  In the event that the Premises or any part thereof, or the whole or<br \/>\nany part of the Building, shall be taken or appropriated by eminent domain or<br \/>\nshall be condemned for any public or quasi-public use, or (by virtue of any such<br \/>\ntaking, appropriation or condemnation) shall suffer any damage (direct, indirect<br \/>\nor consequential) for which Landlord or Tenant shall be entitled to<br \/>\ncompensation, then (and in any such event) this Lease and the term hereof may be<br \/>\nterminated at<\/p>\n<p>                                      -53-<br \/>\n   62<\/p>\n<p>the election of Landlord by a notice in writing of its election so to terminate<br \/>\nwhich shall be given by Landlord to Tenant within sixty (60) days following the<br \/>\ndate on which Landlord shall have received notice of such taking, appropriation<br \/>\nor condemnation. In the event that a substantial part of the Premises or of the<br \/>\nmeans of access thereto shall be so taken, appropriated or condemned, then (and<br \/>\nin any such event) this Lease and the term hereof may be terminated at the<br \/>\nelection of Tenant by a notice in writing of its election so to terminate which<br \/>\nshall be given by Tenant to Landlord within sixty (60) days following the date<br \/>\non which Tenant shall have received notice of such taking, appropriation or<br \/>\ncondemnation.<\/p>\n<p>     (b)  Upon the giving of any such notice of termination (either by Landlord<br \/>\nor Tenant) this Lease and the term hereof shall terminate on or retroactively as<br \/>\nof the date on which Tenant shall be required to vacate any part of the Premises<br \/>\nor shall be deprived of a substantial part of the means of access thereto,<br \/>\nprovided, however, that Landlord may in Landlord&#8217;s notice elect to terminate<br \/>\nthis Lease and the term hereof retroactively as of the date on which such<br \/>\ntaking, appropriation or condemnation became legally effective. In the event of<br \/>\nany such termination, this Lease and the term hereof shall expire as of such<br \/>\neffective termination date as though that were the Termination Date as stated in<br \/>\nExhibit 1, and the Yearly Rent shall be apportioned as of such date.<\/p>\n<p>     (c)  If a Restructuring Rent Event, as defined in Paragraph 1 of the Rider<br \/>\nto this Lease, occurs, and if Landlord draws upon any Letter of Credit which<br \/>\nLandlord is holding pursuant to Paragraph 1 of the Rider to this Lease for the<br \/>\npurpose of making a Restructuring Rent Payment, AND if the Lease is subsequently<br \/>\nterminated by either party pursuant to this Article 20 based upon taking or<br \/>\ncondemnation, as aforesaid, then Landlord shall, within thirty (30) days of the<br \/>\neffective termination date of such taking, pay to Tenant a Taking Termination<br \/>\nPayment, as hereinafter defined. The &#8220;Taking Termination Payment&#8221; shall be<br \/>\ndefined as the amount of principal which would remain unpaid at the effective<br \/>\ntermination date on a loan (i) in the original principal amount of the<br \/>\nRestructuring Rent Payment, (ii) with interest at the rate of the rate per annum<br \/>\nannounced by Fleet Bank, N.A., or its successor, from time to time as its<br \/>\n&#8220;prime&#8221; rate, plus one-quarter percent (1\/4%), (iii) which is repaid on a direct<br \/>\nreduction basis in equal monthly payments of principal and interest, and (iv)<br \/>\nwith a term commencing with the application of the Restructuring Rent Payment<br \/>\nand ending as of the expiration of the then-current term of the Lease. If, prior<br \/>\nto the termination of the Lease based upon a taking, there have been two<br \/>\nRestructuring Rent Payments pursuant to Paragraph 1.C.6 of the Rider to this<br \/>\nLease, the Taking Termination Payment shall be calculated separately for each<br \/>\nsuch Restructuring Rent Payment.<\/p>\n<p>     (d)  If neither party (having the right so to do) elects to terminate<br \/>\nLandlord will, with reasonable diligence and at Landlord&#8217;s expense, restore the<br \/>\nremainder of the Premises, or the remainder of the means of access, as nearly as<br \/>\npracticably may be to the same condition as obtained prior to such taking,<br \/>\nappropriation or condemnation in which event (i) the Total Rentable Area shall<br \/>\nbe equitably adjusted, (ii) a just proportion of the Yearly Rent, according to<br \/>\nthe nature and extent of the taking, appropriation or condemnation and the<br \/>\nresulting permanent injury to the Premises and the means of access thereto,<br \/>\nshall be permanently abated, and (iii) a just proportion of the remainder of the<br \/>\nYearly Rent, according to the nature and extent of the taking, appropriation or<br \/>\ncondemnation and the resultant injury sustained by the Premises and the means of<br \/>\naccess thereto, shall be abated until what remains of the Premises and the means<br \/>\nof access thereto shall have been restored as fully as may be for permanent use<br \/>\nand occupation by Tenant hereunder. Except for any award specifically<br \/>\nreimbursing Tenant for moving or relocation expenses, there are expressly<br \/>\nreserved to Landlord all rights to compensation and<\/p>\n<p>                                      -54-<br \/>\n   63<\/p>\n<p>damages created, accrued or accruing by reason of any such taking, appropriation<br \/>\nor condemnation, in implementation and in confirmation of which Tenant does<br \/>\nhereby acknowledge that Landlord shall be entitled to receive all such<br \/>\ncompensation and damages, grant to Landlord all and whatever rights (if any)<br \/>\nTenant may have to such compensation and damages, and agree to execute and<br \/>\ndeliver all and whatever further instruments of assignment as Landlord may from<br \/>\ntime to time request. In the event of any taking of the Premises or any part<br \/>\nthereof for temporary (i.e., not in excess of one (1) year) use, (i) this Lease<br \/>\nshall be and remain unaffected thereby, and (ii) Tenant shall be entitled to<br \/>\nreceive for itself any award made to the extent allocable to the Premises in<br \/>\nrespect of such taking on account of such use, provided, that if any taking is<br \/>\nfor a period extending beyond the term of this Lease, such award shall be<br \/>\napportioned between Landlord and Tenant as of the Termination Date or earlier<br \/>\ntermination of this Lease.<\/p>\n<p>21.

Landlord shall pay, upon demand by Tenant, reasonable attorneys&#8217; fees<br \/>\nincurred by Tenant in connection with any lawsuit between Landlord and Tenant<br \/>\nwhere judgment is entered (final, and beyond appeal) in favor of Tenant.<\/p>\n<p>     21.5 WAIVER OF REDEMPTION. Tenant does hereby waive and surrender all<br \/>\nrights and privileges which it might have under or by reason of any present or<br \/>\nfuture law to redeem the Premises or to have a continuance of this Lease for the<br \/>\nterm hereby demised after being<\/p>\n<p>                                      -57-<br \/>\n   66<\/p>\n<p>dispossessed or ejected therefrom by process of law or under the terms of this<br \/>\nLease or after the termination of this Lease as herein provided.<\/p>\n<p>     21.6 LANDLORD&#8217;S REMEDIES NOT EXCLUSIVE. The specified remedies to which<br \/>\nLandlord may resort hereunder are cumulative and are not intended to be<br \/>\nexclusive of any remedies or means of redress to which Landlord may at any time<br \/>\nbe lawfully entitled, and Landlord may invoke any remedy (including the remedy<br \/>\nof specific performance) allowed at law or in equity as if specific remedies<br \/>\nwere not herein provided for.<\/p>\n<p>     21.7 GRACE PERIOD.

Tenant<br \/>\nshall remove all of its property and, to the extent specified by Landlord, all<br \/>\nalterations and additions made by Tenant and all partitions wholly within the<br \/>\nPremises, and shall repair any damages to the Premises or the Building caused by<br \/>\ntheir installation or by such removal. Tenant&#8217;s obligation to observe or perform<br \/>\nthis covenant shall survive the expiration or other termination of the term of<br \/>\nthis Lease.<\/p>\n<p>                                      -58-<br \/>\n   67<\/p>\n<p>     Tenant will remove any personal property from the Building and the Premises<br \/>\nupon or prior to the expiration or termination of this Lease and any such<br \/>\nproperty which shall remain in the Building or the Premises thereafter shall be<br \/>\nconclusively deemed to have been abandoned, and may either be retained by<br \/>\nLandlord as its property or sold or otherwise disposed of in such manner as<br \/>\nLandlord may see fit. If any part thereof shall be sold, that Landlord may<br \/>\nreceive and retain the proceeds of such sale and apply the same, at its option,<br \/>\nagainst the expenses of the sale, the cost of moving and storage, any arrears of<br \/>\nYearly Rent, additional or other charges payable hereunder by Tenant to Landlord<br \/>\nand any damages to which Landlord may be entitled under Article 21 hereof or<br \/>\npursuant to law.<\/p>\n<p>     If Tenant or anyone claiming under Tenant shall remain in possession of the<br \/>\nPremises or any part thereof after the expiration or prior termination of the<br \/>\nterm of this Lease without any agreement in writing between Landlord and Tenant<br \/>\nwith respect thereto, then, prior to the acceptance of any payments for rent or<br \/>\nuse and occupancy by Landlord, the person remaining in possession shall be<br \/>\ndeemed a tenant-at-sufferance. Whereas the parties hereby acknowledge that<br \/>\nLandlord may need the Premises after the expiration or prior termination of the<br \/>\nterm of the Lease for other tenants and that the damages which Landlord may<br \/>\nsuffer as the result of Tenant&#8217;s holding-over cannot be determined as of the<br \/>\nExecution Date hereof, in the event that Tenant so holds over, Tenant shall pay<br \/>\nto Landlord in addition to all rental and other charges due and accrued under<br \/>\nthe Lease prior to the date of termination, charges (based upon fair market<br \/>\nrental value of the Premises) for use and occupation of the Premises thereafter<br \/>\nand, in addition to such sums and any and all other rights and remedies which<br \/>\nLandlord may have at law or in equity, an additional use and occupancy charge in<br \/>\nthe amount of fifty percent (50%) of either the Yearly Rent and other charges<br \/>\ncalculated (on a daily basis) at the highest rate payable under the terms of<br \/>\nthis Lease, but measured from the day on which Tenant&#8217;s hold-over commenced and<br \/>\nterminating on the day on which Tenant vacates the Premises or the fair market<br \/>\nvalue of the Premises for such period, whichever is greater. In addition, Tenant<br \/>\nshall save Landlord, its agents and employees, harmless and will exonerate,<br \/>\ndefend and indemnify Landlord, its agents and employees, from and against any<br \/>\nand all damages which Landlord may suffer on account of Tenant&#8217;s hold-over in<br \/>\nthe Premises after the expiration or prior termination of the term of the Lease.<br \/>\nNotwithstanding the foregoing, Tenant shall not be liable for consequential<br \/>\ndamages incurred by Landlord based upon any holdover by Tenant after the<br \/>\nexpiration or prior termination of the term of the Lease unless such holdover<br \/>\ncontinues for sixty (60) or more days after the termination of this Lease or<br \/>\nTenant&#8217;s right to possession.<\/p>\n<p>23.  SUBORDINATION<\/p>\n<p>     (a)  Subject to any mortgagee&#8217;s or ground lessor&#8217;s election, as hereinafter<br \/>\nprovided for, this Lease is subject and subordinate in all respects to all<br \/>\nmatters of record (including, without limitation, deeds and land disposition<br \/>\nagreements), ground leases and\/or underlying leases, and all mortgages, any of<br \/>\nwhich may now or hereafter be placed on or affect such leases and\/or the real<br \/>\nproperty of which the Premises are a part, or any part of such real property,<br \/>\nand\/or Landlord&#8217;s interest or estate therein, and to each advance made and\/or<br \/>\nhereafter to be made under any such mortgages, and to all renewals,<br \/>\nmodifications, consolidations, replacements and extensions thereof and all<br \/>\nsubstitutions therefor. This Article 23 shall be self-operative and no further<br \/>\ninstrument or subordination shall be required. In confirmation of such<br \/>\nsubordination, Tenant shall execute, acknowledge and deliver promptly any<br \/>\ncertificate or instrument that Landlord and\/or any mortgagee and\/or lessor under<br \/>\nany ground or underlying lease and\/or their respective successors in interest<br \/>\nmay request, subject to Landlord&#8217;s, mortgagee&#8217;s and ground<\/p>\n<p>                                      -59-<br \/>\n   68<\/p>\n<p>lessor&#8217;s right to do so for, on behalf and in the name of Tenant under certain<br \/>\ncircumstances, as hereinafter provided. Tenant acknowledges that, where<br \/>\napplicable, any consent or approval hereafter given by Landlord may be subject<br \/>\nto the further consent or approval of such mortgagee and\/or ground lessor; and<br \/>\nthe failure or refusal of such mortgagee and\/or ground lessor to give such<br \/>\nconsent or approval shall, notwithstanding anything to the contrary in this<br \/>\nLease contained, constitute reasonable justification for Landlord&#8217;s withholding<br \/>\nits consent or approval. Landlord hereby represents to Tenant that, as of the<br \/>\nExecution Date of this Lease, there is no mortgage affecting the Premises or the<br \/>\nBuilding. Notwithstanding anything to the contrary in this Article 23 contained,<br \/>\nas to any future mortgages, ground leases, and\/or underlying lease or deeds of<br \/>\ntrust, the herein provided subordination and attornment shall be effective only<br \/>\nif the mortgagee, ground lessor or trustee therein, as the case may be, agrees,<br \/>\nby a written instrument in recordable form and in the customary form of such<br \/>\nmortgagee, ground lessor, or trustee (&#8220;Nondisturbance Agreement&#8221;) that, as long<br \/>\nas Tenant shall not be in terminable default of the obligations on its part to<br \/>\nbe kept and performed under the terms of this Lease, this Lease will not be<br \/>\naffected and Tenant&#8217;s possession hereunder will not be disturbed by any default<br \/>\nin, termination, and\/or foreclosure of, such mortgage, ground lease, and\/or<br \/>\nunderlying lease or deed of trust, as the case may be.<\/p>\n<p>     (b)  Any such mortgagee or ground lessor may from time to time subordinate<br \/>\nor revoke any such subordination of the mortgage or ground lease held by it to<br \/>\nthis Lease. Such subordination or revocation, as the case may be, shall be<br \/>\neffected by written notice to Tenant and by recording an instrument of<br \/>\nsubordination or of such revocation, as the case may be, with the appropriate<br \/>\nregistry of deeds or land records and to be effective without any further act or<br \/>\ndeed on the part of Tenant. In confirmation of such subordination or of such<br \/>\nrevocation, as the case may be, Tenant shall execute, acknowledge and promptly<br \/>\ndeliver any certificate or instrument that Landlord, any mortgagee or ground<br \/>\nlessor may request, subject to Landlord&#8217;s, mortgagee&#8217;s and ground lessor&#8217;s right<br \/>\nto do so for, on behalf and in the name of Tenant under certain circumstances,<br \/>\nas hereinafter provided.<\/p>\n<p>     (c)  Without limitation of any of the provisions of this Lease, if any<br \/>\nground lessor or mortgagee shall succeed to the interest of Landlord by reason<br \/>\nof the exercise of its rights under such ground lease or mortgage (or the<br \/>\nacceptance of voluntary conveyance in lieu thereof) or any third party<br \/>\n(including, without limitation, any foreclosure purchaser or mortgage receiver)<br \/>\nshall succeed to such interest by reason of any such exercise or the expiration<br \/>\nor sooner termination of such ground lease, however caused, then such successor<br \/>\nmay, upon notice and request to Tenant (which, in the case of a ground lease,<br \/>\nshall be within thirty (30) days after such expiration or sooner termination),<br \/>\nsucceed to the interest of Landlord under this Lease, provided, however, that<br \/>\nsuch successor shall not: (i) be liable for any previous act or omission of<br \/>\nLandlord under this Lease; (ii) be subject to any offset, defense, or<br \/>\ncounterclaim which shall theretofore have accrued to Tenant against Landlord;<br \/>\n(iii) have any obligation with respect to any letter of credit unless it shall<br \/>\nhave been physically delivered to such successor; or (iv) be bound by any<br \/>\nprevious modification of this Lease or by any previous payment of Yearly Rent<br \/>\nfor a period greater than one (1) month, made without such ground lessor&#8217;s or<br \/>\nmortgagee&#8217;s consent where such consent is required by applicable ground lease or<br \/>\nmortgage documents. In the event of such succession to the interest of the<br \/>\nLandlord &#8212; and notwithstanding that any such mortgage or ground lease may<br \/>\nantedate this Lease &#8212; the Tenant shall attorn to such successor and shall ipso<br \/>\nfacto be and become bound directly to such successor in interest to Landlord to<br \/>\nperform and observe all the Tenant&#8217;s obligations under this Lease without the<br \/>\nnecessity of the execution of any further instrument. Nevertheless, Tenant<br \/>\nagrees at any time and from time to time during the term<\/p>\n<p>                                      -60-<br \/>\n   69<\/p>\n<p>hereof to execute a suitable instrument in confirmation of Tenant&#8217;s agreement to<br \/>\nattorn, as aforesaid, subject to Landlord&#8217;s, mortgagee&#8217;s and ground lessor&#8217;s<br \/>\nright to do so for, on behalf and in the name of Tenant under certain<br \/>\ncircumstances, as hereinafter provided.<\/p>\n<p>     (d)  The term &#8220;mortgage(s)&#8221; as used in this Lease shall include any<br \/>\nmortgage or deed of trust. The term &#8220;mortgagee(s)&#8221; as used in this Lease shall<br \/>\ninclude any mortgagee or any trustee and beneficiary under a deed of trust or<br \/>\nreceiver appointed under a mortgage or deed of trust. The term &#8220;mortgagor(s)&#8221; as<br \/>\nused in this Lease shall include any mortgagor or any grantor under a deed of<br \/>\ntrust.<\/p>\n<p>     (e)  Tenant hereby irrevocably constitutes and appoints Landlord or any<br \/>\nsuch mortgagee or ground lessor, and their respective successors in interest,<br \/>\nacting singly, Tenant&#8217;s attorney-in-fact to execute and deliver any such<br \/>\ncertificate or instrument for, on behalf and in the name of Tenant, but only if<br \/>\nTenant fails to execute, acknowledge and deliver any such certificate or<br \/>\ninstrument within twenty (20) days after Landlord or such mortgagee or such<br \/>\nground lessor has made written request therefor.<\/p>\n<p>     (f)  Notwithstanding anything to the contrary contained in this Article 23,<br \/>\nif all or part of Landlord&#8217;s estate and interest in the real property of which<br \/>\nthe Premises are a part shall be a leasehold estate held under a ground lease,<br \/>\nthen: (i) the foregoing subordination provisions of this Article 23 shall not<br \/>\napply to any mortgages of the fee interest in said real property to which<br \/>\nLandlord&#8217;s leasehold estate is not otherwise subject and subordinate; and (ii)<br \/>\nthe provisions of this Article 23 shall in no way waive, abrogate or otherwise<br \/>\naffect any agreement by any ground lessor (x) not to terminate this Lease<br \/>\nincident to any termination of such ground lease prior to its term expiring or<br \/>\n(y) not to name or join Tenant in any action or proceeding by such ground lessor<br \/>\nto recover possession of such real property or for any other relief. As of the<br \/>\nExecution Date of this Lease, there is no ground lease of the Building or the<br \/>\nreal property of which the Building is a part.<\/p>\n<p>     (g)  In the event of any failure by Landlord to perform, fulfill or observe<br \/>\nany agreement by Landlord herein, in no event will the Landlord be deemed to be<br \/>\nin default under this Lease permitting Tenant to exercise any or all rights or<br \/>\nremedies under this Lease until the Tenant shall have given written notice of<br \/>\nsuch failure to any mortgagee (ground lessor and\/or trustee) of which Tenant<br \/>\nshall have been advised and until a reasonable period of time shall have elapsed<br \/>\nfollowing the giving of such notice, during which such mortgagee (ground lessor<br \/>\nand\/or trustee) shall have the right, but shall not be obligated, to remedy such<br \/>\nfailure.<\/p>\n<p>24.  QUIET ENJOYMENT<\/p>\n<p>     Landlord covenants that if, and so long as, Tenant keeps and performs each<br \/>\nand every covenant, agreement, term, provision and condition herein contained on<br \/>\nthe part and on behalf of Tenant to be kept and performed, Tenant shall quietly<br \/>\nenjoy the Premises from and against the claims of all persons claiming by,<br \/>\nthrough or under Landlord subject, nevertheless, to the covenants, agreements,<br \/>\nterms, provisions and conditions of this Lease and to the mortgages, ground<br \/>\nleases and\/or underlying leases to which this Lease is subject and subordinate,<br \/>\nas hereinabove set forth.<\/p>\n<p>     Without incurring any liability to Tenant, Landlord may permit access to<br \/>\nthe Premises and open the same, whether or not Tenant shall be present, upon any<br \/>\ndemand of any receiver,<\/p>\n<p>                                      -61-<br \/>\n   70<\/p>\n<p>trustee, assignee for the benefit of creditors, sheriff, marshal or court<br \/>\nofficer entitled to, or reasonably purporting to be entitled to, such access for<br \/>\nthe purpose of taking possession of, or removing, Tenant&#8217;s property or for any<br \/>\nother lawful purpose (but this provision and any action by Landlord hereunder<br \/>\nshall not be deemed a recognition by Landlord that the person or official making<br \/>\nsuch demand has any right or interest in or to this Lease, or in or to the<br \/>\nPremises), or upon demand of any representative of the fire, police, building,<br \/>\nsanitation or other department of the city, state or federal governments.<\/p>\n<p>25.  ENTIRE AGREEMENT &#8212; WAIVER &#8212; SURRENDER<\/p>\n<p>     25.1 ENTIRE AGREEMENT. This Lease and the Exhibits made a part hereof<br \/>\ncontain the entire and only agreement between the parties and any and all<br \/>\nstatements and representations, written and oral, including previous<br \/>\ncorrespondence and agreements between the parties hereto, are merged herein.<br \/>\nTenant acknowledges that all representations and statements upon which it relied<br \/>\nin executing this Lease are contained herein and that the Tenant in no way<br \/>\nrelied upon any other statements or representations, written or oral. Any<br \/>\nexecutory agreement hereafter made shall be ineffective to change, modify,<br \/>\ndischarge or effect an abandonment of this Lease in whole or in part unless such<br \/>\nexecutory agreement is in writing and signed by the party against whom<br \/>\nenforcement of the change, modification, discharge or abandonment is sought.<\/p>\n<p>     25.2 WAIVER. The failure of either party to seek redress for violation, or<br \/>\nto insist upon the strict performance, of any covenant or condition of this<br \/>\nLease, or any of the Rules and Regulations promulgated hereunder, shall not<br \/>\nprevent a subsequent act, which would have originally constituted a violation,<br \/>\nfrom having all the force and effect of an original violation. The receipt by<br \/>\nLandlord of rent with knowledge of the breach of any covenant of this Lease<br \/>\nshall not be deemed a waiver of such breach. The failure of Landlord to enforce<br \/>\nany of such Rules and Regulations against Tenant and\/or any other tenant in the<br \/>\nBuilding shall not be deemed a waiver of any such Rules and Regulations. No<br \/>\nprovisions of this Lease shall be deemed to have been waived by either party<br \/>\nunless such waiver be in writing signed by such party. No payment by Tenant or<br \/>\nreceipt by Landlord of a lesser amount than the monthly rent herein stipulated<br \/>\nshall be deemed to be other than on account of the stipulated rent, nor shall<br \/>\nany endorsement or statement on any check or any letter accompanying any check<br \/>\nor payment as rent be deemed an accord and satisfaction, and Landlord may accept<br \/>\nsuch check or payment without prejudice to Landlord&#8217;s right to recover the<br \/>\nbalance of such rent or pursue any other remedy in this Lease provided.<\/p>\n<p>     25.3 SURRENDER. No act or thing done by Landlord during the term hereby<br \/>\ndemised shall be deemed an acceptance of a surrender of the Premises, and no<br \/>\nagreement to accept such surrender shall be valid, unless in writing signed by<br \/>\nLandlord. No employee of Landlord or of Landlord&#8217;s agents shall have any power<br \/>\nto accept the keys of the Premises prior to the termination of this Lease. The<br \/>\ndelivery of keys to any employee of Landlord or of Landlord&#8217;s agents shall not<br \/>\noperate as a termination of the Lease or a surrender of the Premises. In the<br \/>\nevent that Tenant at any time desires to have Landlord underlet the Premises for<br \/>\nTenant&#8217;s account, Landlord or Landlord&#8217;s agents are authorized to receive the<br \/>\nkeys for such purposes without releasing Tenant from any of the obligations<br \/>\nunder this Lease, and Tenant hereby relieves Landlord of any liability for loss<br \/>\nof or damage to any of Tenant&#8217;s effects in connection with such underletting.<\/p>\n<p>                                      -62-<br \/>\n   71<\/p>\n<p>26.

In each such instance of<br \/>\ninability of Landlord to perform, Landlord shall exercise reasonable diligence<br \/>\nto eliminate the cause of such inability to perform.<\/p>\n<p>     Tenant shall neither assert nor seek to enforce any claim against Landlord,<br \/>\nor Landlord&#8217;s agents or employees, or the assets of Landlord or of Landlord&#8217;s<br \/>\nagents or employees, for breach of this Lease or otherwise, other than against<br \/>\nLandlord&#8217;s interest in the Building of which the Premises are a part and the<br \/>\nComplex and in the uncollected rents, issues and profits thereof, and Tenant<br \/>\nagrees to look solely to such interest for the satisfaction of any liability of<br \/>\nLandlord under this Lease, it being specifically agreed that in no event shall<br \/>\nLandlord or Landlord&#8217;s agents or employees (or any of the officers, trustees,<br \/>\ndirectors, partners, beneficiaries, joint venturers, members, stockholders or<br \/>\nother principals or representatives, and the like, disclosed or undisclosed,<br \/>\nthereof) ever be personally liable for any such liability. This paragraph shall<br \/>\nnot limit any right that Tenant might otherwise have to obtain injunctive relief<br \/>\nagainst Landlord or to take any other action which shall not involve the<br \/>\npersonal liability of Landlord to respond in monetary damages from Landlord&#8217;s<br \/>\nassets other than the Landlord&#8217;s interest in said real estate, as aforesaid. In<br \/>\nno event shall Landlord or Landlord&#8217;s agents or employees (or any of the<br \/>\nofficers, trustees, directors, partners, beneficiaries, joint venturers,<br \/>\nmembers, stockholders or other principals or representatives and the like,<br \/>\ndisclosed or undisclosed, thereof) ever be liable for consequential or<br \/>\nincidental damages. Without limiting the foregoing, in no event shall Landlord<br \/>\nor Landlord&#8217;s agents or employees (or any of the officers, trustees, directors,<br \/>\npartners, beneficiaries, joint venturers, members, stockholders or other<br \/>\nprincipals or representatives and the like, disclosed or undisclosed, thereof)<br \/>\never be liable for lost profits of Tenant.

LETTERS OF CREDIT<\/p>\n<p>     A.   DELIVERY OF LETTERS OF CREDIT. Tenant shall deliver to Landlord, on<br \/>\nthe date that Tenant executes and delivers the Lease to Landlord, an Irrevocable<br \/>\nStandby Letter of Credit (&#8220;Initial Letter of Credit&#8221;) which shall be (1) in the<br \/>\nform attached hereto as Exhibit 5, (2) issued by a bank reasonably acceptable to<br \/>\nLandlord upon which presentment may be made in Boston, Massachusetts, (3) in the<br \/>\nLetter of Credit Amount, as hereinafter defined, and (4) for a term of one (1)<br \/>\nyear, subject to extension in accordance with the terms of the Letter of Credit.<br \/>\nThe Letter of Credit Amount shall initially be $5,114,070.00. In addition,<br \/>\nTenant shall, on the Term Commencement Date, deliver to Landlord either: (i) an<br \/>\namendment to the Initial Letter of Credit, in form reasonably acceptable to<br \/>\nLandlord, increasing the Letter of Credit Amount from $5,114,070.00 to<br \/>\n$10,228,140.00 (&#8220;Letter of Credit Amendment&#8221;), or (ii) a second Letter of Credit<br \/>\nconforming to the requirements of this Subparagraph A (&#8220;Second Letter of<br \/>\nCredit&#8221;), in the amount of $5,114,070.00. Tenant&#8217;s failure to deliver either the<br \/>\nLetter of Credit Amendment or the Second Letter of Credit shall be deemed to be<br \/>\na default by Tenant in its obligations under the Lease with the same notice and<br \/>\ncure period as would be applicable as if such failure were a failure to pay<br \/>\nYearly Rent when due under the Lease. If Tenant elects to provide a Second<br \/>\nLetter of Credit in lieu of a Letter of Credit Amendment, then the Initial<br \/>\nLetter of Credit and the Second Letter of Credit shall be collectively referred<br \/>\nto herein as the &#8220;Letter of Credit&#8221; and the Letter of Credit Amount shall be<br \/>\ndefined as the sum of the amounts of Initial Letter of Credit and the Second<br \/>\nLetter of Credit. The Letter of Credit shall be subject to reduction as set<br \/>\nforth below. Tenant shall, on or before the date thirty (30) days prior to the<br \/>\nexpiration of the term of the Letter of Credit, deliver to Landlord a new Letter<br \/>\nof Credit satisfying the foregoing conditions (&#8220;Substitute Letter of Credit&#8221;) in<br \/>\nlieu of the Letter of Credit then being held by Landlord. Such Letter of Credit<br \/>\nshall be automatically renewable in accordance with the second to last<br \/>\ngrammatical paragraph of Exhibit 5; provided that, in such event, Tenant shall<br \/>\nbe required to deliver a Substitute Letter of Credit satisfying the conditions<br \/>\nhereof, on or before the date thirty (30) days prior to the expiration of the<br \/>\nterm of such Letter of Credit, if the issuer of such Letter of Credit gives<br \/>\nnotice of its election not to renew such Letter of Credit for any additional<br \/>\nperiod pursuant thereto. Upon written request of Tenant, Landlord shall deliver<br \/>\nto the issuing bank an instruction authorizing the issuing bank to reduce the<br \/>\nLetter of Credit Amount in accordance with the schedule set forth herein.<\/p>\n<p>     B.   RENT RESTRUCTURING EVENT. A &#8220;Rent Restructuring Event&#8221; shall be<br \/>\ndefined as :<\/p>\n<p>     1.   Any monetary default or material non-monetary default by Tenant in its<br \/>\n     obligations under the Lease which is not cured after the giving of any<br \/>\n     applicable notice and the expiration of any applicable grace periods<br \/>\n     (&#8220;Event of Default&#8221;); or<\/p>\n<p>     2.   If, at any time, both of the following conditions occur: (i) the price<br \/>\n     per share for Tenant&#8217;s common stock as traded on a nationally-recognized<br \/>\n     exchange and calculated on the basis of a thirty (30) day trailing average<br \/>\n     and adjusted for any stock splits, reverse<\/p>\n<p>                                      -80-<br \/>\n   89<\/p>\n<p>     stock splits or mergers from and after the Execution Date, is less than<br \/>\n     $20.00 (a &#8220;Low Stock Price Event&#8221;), and (ii) Tenant does not, within ten<br \/>\n     (10) days after notice from Landlord that Landlord claims that such Low<br \/>\n     Stock Price Event constitutes a Rent Restructuring Event, provide Landlord<br \/>\n     with a certification from Tenant&#8217;s Chief Financial Officer, or from the<br \/>\n     independent certified public accountant that prepared Tenant&#8217;s most recent<br \/>\n     financial statement in accordance with Subparagraph J hereof, or from<br \/>\n     another independent certified public accountant reasonably acceptable to<br \/>\n     Landlord, that, as of the date of Landlord&#8217;s notice, the aggregate amount<br \/>\n     of cash, cash equivalents, and short term investments held by Tenant and<br \/>\n     which is free and clear of any liens or encumbrances is equal to or greater<br \/>\n     than $50,000,000.00.<\/p>\n<p>     C.   EFFECT OF RENT RESTRUCTURING EVENT. If any Rent Restructuring Event<br \/>\noccurs, then:<\/p>\n<p>     1.   If the Rent Restructuring Event is an Event of Default, Landlord may,<br \/>\n     at its election, (a) exercise its rights under Paragraph 1.K of this Rider<br \/>\n     to draw down the Default Draw Amount, and\/or in addition thereto, (b)<br \/>\n     Landlord may, in its sole discretion, draw (i) the balance of the Letter of<br \/>\n     Credit or (ii) fifty percent (50%) of the balance of the Letter of Credit<br \/>\n     and apply such amount as a payment of Yearly Rent under the Lease; or<\/p>\n<p>     2.   If the Rent Restructuring Event is not an Event of Default, Landlord<br \/>\n     may, at its election and in its sole discretion, draw (i) the entire Letter<br \/>\n     of Credit or (ii) fifty percent (50%) of the Letter of Credit, and apply<br \/>\n     such amount as a payment of Yearly Rent under the Lease; and<\/p>\n<p>     3.   Upon the application of any payment pursuant to Clauses 1 or 2 above<br \/>\n     (each of which is referred to herein as a &#8220;Restructuring Rent Payment&#8221;),<br \/>\n     then the amount of monthly payments of Yearly Rent payable by Tenant<br \/>\n     thereafter under the Lease shall be reduced by an amount equal to the<br \/>\n     Monthly Rent Reduction Amount, as hereinafter defined; and<\/p>\n<p>     4.   Except as set forth in Clause 6 of this Paragraph C, in no event shall<br \/>\n     Landlord draw down the Letter of Credit (either in whole or in part) and<br \/>\n     apply the proceeds as a Restructuring Rent Payment more than once during<br \/>\n     the term hereof. Landlord&#8217;s election to draw down the Letter of Credit<br \/>\n     (either in whole or in part) and apply the proceeds as a Restructuring Rent<br \/>\n     Payment must be made within ninety (90) days following the Rent<br \/>\n     Restructuring Event in question (or, in the case of a Rent Restructuring<br \/>\n     Event that continues over a period of time, within ninety (90) days<br \/>\n     following the last day thereof); and<\/p>\n<p>     5.   Landlord&#8217;s right to draw down the Letter of Credit, either in whole or<br \/>\n     in part, and apply the proceeds as a Restructuring Rent Payment, shall<br \/>\n     expire upon the occurrence of both of the following events:<\/p>\n<p>          (a)  At least two (2) years shall have passed since Tenant has<br \/>\n          provided Landlord with the Initial Letter of Credit, and<\/p>\n<p>                                      -81-<br \/>\n   90<\/p>\n<p>          (b)  Tenant&#8217;s Cash Flow (as defined in Subparagraph H below),<br \/>\n          aggregated over four (4) consecutive fiscal quarters (beginning not<br \/>\n          sooner than the quarter containing the first anniversary of the date<br \/>\n          Tenant provides Landlord with the Initial Letter of Credit), is<br \/>\n          positive; and<\/p>\n<p>     6.   If Landlord exercises its right to draw down the Letter of Credit,<br \/>\n     either in whole or in part, and apply the proceeds as a Restructuring Rent<br \/>\n     Payment before the Term Commencement Date, when the Letter of Credit Amount<br \/>\n     is only $5,114,070.00, then when the Letter of Credit Amount is increased<br \/>\n     to $10,228,140.00 after the Term Commencement Date, Landlord shall draw<br \/>\n     down the same percentage of the increased Letter of Credit Amount and apply<br \/>\n     such proceeds as a Restructuring Rent Payment (e.g., if Landlord drew down<br \/>\n     the fifty (50%) of the Initial Letter of Credit, then Landlord shall draw<br \/>\n     down the fifty (50%) percent of Second Letter of Credit, or of the<br \/>\n     increased amount in the Initial Letter of Credit, as affected by the Letter<br \/>\n     of Credit Amendment, as the case may be); and<\/p>\n<p>     7.   Landlord shall have no obligation to draw down the Letter of Credit if<br \/>\n     a Rent Restructuring Event occurs; and<\/p>\n<p>     8.   If a Rent Restructuring Event occurs but Landlord does not exercise<br \/>\n     its right to draw upon the Letter of Credit based upon such Rent<br \/>\n     Restructuring Event, Landlord shall, if the same or a different Rent<br \/>\n     Restructuring Event occurs, have the right to draw upon the Letter of<br \/>\n     Credit to make a Restructuring Rent Payment as if the first such Rent<br \/>\n     Restructuring Event had not previously occurred; and<\/p>\n<p>     9.   If a Rent Restructuring Event occurs and Landlord elects to draw upon<br \/>\n     the Letter of Credit to make a Rent Restructuring Payment, then (except as<br \/>\n     provided in Clause 6 of this Subparagraph C) Landlord shall have no further<br \/>\n     right to draw upon the Letter of Credit to make a subsequent Rent<br \/>\n     Restructuring Payment; provided however, that the provisions of this Clause<br \/>\n     9 shall not affect Landlord from drawing upon the Letter of Credit based<br \/>\n     upon a subsequent Event of Default for the purposes of paying a Default<br \/>\n     Draw Amount, as hereinafter defined, or from drawing upon the Letter of<br \/>\n     Credit pursuant to Subparagraph L of this Paragraph 1, if Tenant fails<br \/>\n     timely to deliver a Substitute Letter of Credit.<\/p>\n<p>     D.   MONTHLY RENT REDUCTION PAYMENT. The &#8220;Monthly Rent Reduction Payment&#8221;<br \/>\nshall be equal to the amount of the monthly payment of principal and interest<br \/>\nwhich would be necessary to fully pay a loan, in the amount of the Restructuring<br \/>\nRent Payment with interest at the rate of the rate per annum announced by Fleet<br \/>\nBank, N.A., or its successor, from time to time as its &#8220;prime&#8221; rate, plus<br \/>\none-quarter percent (1\/4%), which is repaid on a direct reduction basis in equal<br \/>\nmonthly payments of principal and interest over a term commencing with the<br \/>\napplication of the Restructuring Rent Payment and ending as of the expiration of<br \/>\nthe then-current term of the Lease.<\/p>\n<p>     E.   REDUCTION DATE. &#8220;Reduction Date&#8221; shall be defined as the second<br \/>\nanniversary of the Full Rent Commencement Date, and each anniversary of the Full<br \/>\nRent Commencement Date which occurs thereafter during the term of the Lease.<\/p>\n<p>                                      -82-<br \/>\n   91<\/p>\n<p>     F.   REDUCTION CONDITIONS. Tenant shall be deemed to have satisfied the<br \/>\n&#8220;Reduction Conditions&#8221; with respect to any Reduction Date, if, as of such<br \/>\nReduction Date, all of the following are satisfied:<\/p>\n<p>     1.   Tenant is not in monetary default, or in material non-monetary<br \/>\n     default, in either case beyond any applicable notice and cure periods, of<br \/>\n     any of its obligations under the Lease as of such Reduction Date;<\/p>\n<p>     2.   The Lease is in full force and effect; and<\/p>\n<p>     3.   Tenant has not been in either monetary default, or in material<br \/>\n     non-monetary default, in either case beyond any applicable notice and cure<br \/>\n     periods, on more than one occasion during the immediately preceding twelve<br \/>\n     (12) months of the term of the Lease.<\/p>\n<p>     G.   REDUCTION AMOUNT. The &#8220;Reduction Amount&#8221; with respect to any Reduction<br \/>\nDate shall be based upon Tenant&#8217;s Cash Flow, as hereinafter defined, during<br \/>\nTenant&#8217;s last full twelve month fiscal year immediately preceding the Reduction<br \/>\nDate in question, as follows. If Tenant&#8217;s Cash Flow for the immediately<br \/>\npreceding fiscal year is:<\/p>\n<p>     1.   Not positive, then the Reduction Amount shall be zero;<\/p>\n<p>     2.   Positive, but less than or equal to $5,000,000.00, then the Reduction<br \/>\n     Amount shall be $1,000,000.00; or<\/p>\n<p>     3.   More than $5,000,000.00, but less than or equal to $10,000,000.00,<br \/>\n     then the Reduction Amount shall be $1,250,000.00; or<\/p>\n<p>     4.   More than $10,000,000.00, but less than or equal to $15,000,000.00,<br \/>\n     then the Reduction Amount shall be $1,500,000.00; or<\/p>\n<p>     5.   More than $15,000,000.00, but less than or equal to $20,000,000.00,<br \/>\n     then the Reduction Amount shall be $1,750,000.00; or<\/p>\n<p>     6.   Greater than $20,000,000.00, then the Reduction Amount shall be<br \/>\n     $2,000,000.00.<\/p>\n<p>In no event, however, shall the Letter of Credit Amount ever be reduced below<br \/>\n$3,409,380.00.<\/p>\n<p>     H.   DEFINITION OF CASH FLOW. Tenant&#8217;s Cash Flow for any period shall mean<br \/>\nthe sum of (i) Tenant&#8217;s net income attributable to common stock holders, (ii)<br \/>\ninterest on convertible debt that is accrued but not yet paid or payable, (iii)<br \/>\ndepreciation and (iv) amortization, all as reflected in the audited financial<br \/>\nstatements for period in question. Stock compensation amortization may be added<br \/>\nas part of the definition of Cash Flow, provided that said adjustment is as<br \/>\nreported in the audited financial statements of Tenant for the relevant<br \/>\nreporting period.<\/p>\n<p>     I.   EFFECT OF SATISFACTION OF RENT REDUCTION CONDITIONS. If, on any<br \/>\nReduction Date, Tenant satisfies all of the Reduction Conditions, then the<br \/>\nLetter of Credit Amount shall be reduced by the applicable Reduction Amount, if<br \/>\nany. Such reduction in the Letter of Credit Amount may be effected by an<br \/>\namendment, in form reasonably acceptable to Landlord, to the<\/p>\n<p>                                      -83-<br \/>\n   92<\/p>\n<p>existing Letter(s) of Credit then being held by Landlord, or by Tenant&#8217;s<br \/>\ndelivery to Landlord of a substitute Letter of Credit satisfying all of the<br \/>\nrequirements of the Letter of Credit to be provided to Tenant except that the<br \/>\nLetter of Credit Amount for such substitute Letter of Credit shall be in the<br \/>\nappropriately reduced amount. In the latter event, Landlord shall exchange the<br \/>\nLetter(s) of Credit then being held by Landlord for such substitute Letter of<br \/>\nCredit.<\/p>\n<p>     J.   TENANT&#8217;S FINANCIAL STATEMENTS. Tenant shall deliver to Landlord<br \/>\nfinancial statements as and when made publicly available, if Tenant&#8217;s stock is<br \/>\nthen publicly traded. If Tenant&#8217;s stock is not then publicly traded, Tenant<br \/>\nshall deliver to Landlord (i) within ninety (90) days following the end of its<br \/>\nfiscal year, copies of Tenant&#8217;s annual financial statements, prepared by an<br \/>\nindependent certified public accounting firm reasonably acceptable to Landlord<br \/>\nand in form reasonably acceptable to Landlord, and (ii) within forty-five (45)<br \/>\ndays following the end of each of its fiscal quarters, copies of Tenant&#8217;s<br \/>\nquarterly financial statements certified by Tenant&#8217;s chief financial officer and<br \/>\nin form reasonably acceptable to Landlord. All such financial statements shall<br \/>\nbe prepared in accordance with generally accepted accounting principles,<br \/>\nconsistently applied.<\/p>\n<p>     K.   EFFECT OF TENANT DEFAULT. In the event that Tenant is in default of<br \/>\nits obligations under the Lease, beyond the expiration of applicable notice and<br \/>\ngrace periods, then the Landlord shall have the right, at any time after such<br \/>\nevent, without giving any further notice to Tenant, to draw down from said<br \/>\nLetter of Credit (Substitute Letter of Credit or Additional Letter of Credit, as<br \/>\ndefined below, as the case may be) (a) the amount necessary to cure such default<br \/>\nor (b) if such default cannot reasonably be cured by the expenditure of money,<br \/>\nto exercise all rights and remedies Landlord may have on account of such<br \/>\ndefault, the amount which, in Landlord&#8217;s opinion, is necessary to satisfy<br \/>\nTenant&#8217;s liability on account thereof (&#8220;Default Draw Amount&#8221;). The foregoing<br \/>\nshall be in addition to Landlord&#8217;s other rights to draw down the Letter of<br \/>\nCredit (Substitute Letter of Credit or Additional Letter of Credit, as the case<br \/>\nmay be) pursuant to this Paragraph 1.

TENANT&#8217;S OPTION TO EXTEND THE TERM OF THE LEASE<\/p>\n<p>     A.   On the conditions, which conditions Landlord may waive, at its<br \/>\nelection, by written notice to Tenant at any time, (i) that Tenant is not in<br \/>\ndefault of its covenants and obligations under the Lease, and (ii) that Akamai<br \/>\nTechnologies, Inc., itself, or an Assignee or Affiliated Entity (as those terms<br \/>\nare defined in Article 16) collectively are occupying at least seventy percent<br \/>\n(70%) of the Premises then demised to Tenant, both as of the time of option<br \/>\nexercise and as of the commencement of the hereinafter described additional<br \/>\nterm, Tenant shall have the option to extend the term of this Lease for two (2)<br \/>\nadditional five (5) year terms, each such additional term commencing as of the<br \/>\nexpiration of the initial term of the Lease or the previous extension term, as<br \/>\nthe case may be. Tenant may exercise such option to extend by giving Landlord<br \/>\nwritten notice on or before the date fifteen (15) months prior to the expiration<br \/>\ndate of the initial term of the Lease or the previous extension term, as the<br \/>\ncase may be. Upon the timely giving of such notice, the term of this Lease shall<br \/>\nbe deemed extended upon all of the terms and conditions of this Lease, except<br \/>\nthat Landlord shall have no obligation to construct or renovate the Premises and<br \/>\nthat the Yearly Rent, Operating Costs in the Base Year, and Tax Base during such<br \/>\nadditional term shall be as hereinafter set forth. If Tenant fails to give<br \/>\ntimely notice, as aforesaid, Tenant shall have no further right to extend the<br \/>\nterm of this Lease, time being of the essence of this Paragraph 2.<\/p>\n<p>     B.   YEARLY RENT<\/p>\n<p>     The Yearly Rent during the additional term(s) shall be based upon the Fair<br \/>\nMarket Rental Value, as defined in Paragraph 3 of this Rider, as of the<br \/>\ncommencement of the additional term in question, of the Premises then demised to<br \/>\nTenant, provided however, that in no event shall the sum of Yearly Rent,<br \/>\nOperating Expense Excess and Tax Excess payable by Tenant for any twelve-(12)-<br \/>\nmonth period during an additional term be less than the sum of Yearly Rent,<br \/>\nOperating Expense Excess and Tax Excess payable by Tenant in respect of the<br \/>\ntwelve-(12)-month period immediately preceding the commencement of the<br \/>\nadditional term. Tenant shall have the right, on and after the date eighteen<br \/>\n(18) months prior to the expiration date of the initial term of the Lease or the<br \/>\nprevious extension term, as the case may be, to request in writing that Landlord<br \/>\nadvise Tenant of Landlord&#8217;s designation of the Fair Market Rental Value<br \/>\napplicable during the additional term. Landlord shall, within thirty (30) days<br \/>\nafter receipt of Tenant&#8217;s request, advise Tenant in writing of such designation<br \/>\nof the Fair Market Rental Value.<\/p>\n<p>     C.   TENANT&#8217;S TERMINATION RIGHT AFTER THE FAIR MARKET RENTAL VALUE IN<br \/>\n          RESPECT OF AN ADDITIONAL TERM IS DETERMINED.<\/p>\n<p>                                      -85-<br \/>\n   94<\/p>\n<p>     If Tenant has exercised its right to extend the term of the Lease in<br \/>\nrespect of an additional term, and if Tenant, in accordance with Subparagraph<br \/>\n(C) of Paragraph 3 of this Rider, timely elects to arbitrate the Fair Market<br \/>\nRental Value applicable to such additional term, Tenant shall have the right to<br \/>\nterminate the term of the Lease as follows: Tenant may exercise such right by<br \/>\ngiving written notice to Landlord on or before the date fifteen (15) days after<br \/>\nthe Yearly Rent for the extension term is either agreed to by the parties or is<br \/>\ndetermined by the arbitrators, as the case may be. The effective termination<br \/>\ndate shall be the later of (i) twelve (12) months after Landlord receives such<br \/>\ntermination notice from Tenant, or (ii) the date that this Lease would have<br \/>\nexpired had Tenant not exercised the extension option in question. If Tenant<br \/>\ntimely exercises such termination right, then: (i) the Yearly Rent payable by<br \/>\nTenant for the period commencing as of the day after the expiration of the then<br \/>\ncurrent term of the Lease through the effective termination date shall be based<br \/>\nupon the Fair Market Rental Value, as determined by the arbitrators or as agreed<br \/>\nto by the parties, as the case may be, and (ii) Tenant shall be required to<br \/>\nreimburse Landlord, within ten (10) days of billing therefor, for any and all<br \/>\nreasonable out-of-pocket expenses incurred by Landlord in connection with the<br \/>\narbitration proceedings; and (iii) Landlord shall have the right, by notice<br \/>\n(&#8220;Landlord&#8217;s Extension Notice&#8221;) given to Tenant within thirty (30) days after<br \/>\nthe receipt of Tenant&#8217;s termination notice, to extend the Term of the Lease for<br \/>\na period ending on the date eighteen (18) months after the expiration of the<br \/>\nTerm, prior to any extension pursuant to Paragraph C above (&#8220;Short Extended<br \/>\nTerm&#8221;). If Landlord timely gives Landlord&#8217;s Extension Notice, then the Term of<br \/>\nthe Lease shall be automatically extended for the Short Extended Term and the<br \/>\nYearly Rent during the Short Extended Term shall be based upon the Fair Market<br \/>\nRental Value, as determined by the arbitrators or as agreed to by the parties,<br \/>\nas the case may be.<\/p>\n<p>     D.   Tenant shall have no further option to extend the term of the Lease<br \/>\nother than the two (2) additional five (5) year terms herein provided.<\/p>\n<p>     E.   Notwithstanding the fact that upon Tenant&#8217;s exercise of the herein<br \/>\noption(s) to extend the term of the Lease such extension shall be<br \/>\nself-executing, as aforesaid, the parties shall promptly execute a lease<br \/>\namendment reflecting such additional term after Tenant exercises the herein<br \/>\noption, except that the Yearly Rent payable in respect of such additional term,<br \/>\nthe Operating Costs in the Base Year during such additional term, and the Tax<br \/>\nBase during such additional term, may not be set forth in said amendment.<br \/>\nSubsequently, after such Yearly Rent, Operating Costs in the Base Year, and Tax<br \/>\nBase are determined, the parties shall execute a written agreement confirming<br \/>\nthe same. The execution of such lease amendment shall not be deemed to waive any<br \/>\nof the conditions to Tenant&#8217;s exercise of its rights under this Paragraph 2,<br \/>\nunless otherwise specifically provided in such lease amendment.<\/p>\n<p>3.

In<br \/>\ndetermining Fair Market Rental Value, the following factors, among others, shall<br \/>\nbe taken into account and given effect: size, location of Premises, lease term,<br \/>\ncondition of building, economic concessions then being granted by the landlord,<br \/>\nthe absence of certain costs to be incurred by landlord (e.g., brokerage<br \/>\ncommissions, tenant improvement costs), and services provided by the landlord.<\/p>\n<p>     B.   Notwithstanding anything to the contrary herein contained, the parties<br \/>\nhereby agree that upon the determination of any Fair Market Rental Value,<br \/>\nLandlord shall have the right, exercisable by written notice to Tenant on or<br \/>\nbefore the time that Landlord gives Tenant its initial designation of Fair<br \/>\nMarket Rental Value:<\/p>\n<p>          (1)  to change Operating Costs in the Base Year as stated on Exhibit 1<br \/>\n               from the amount stated on Exhibit 1 to an amount equal to the<br \/>\n               actual amount of Operating Costs for the immediately preceding<br \/>\n               Operating Year, and<\/p>\n<p>          (2)  to change the Tax Base as stated on Exhibit 1 from the amount<br \/>\n               stated on Exhibit 1 to an amount equal to the actual amount of<br \/>\n               Taxes for the immediately preceding fiscal\/tax year for which<br \/>\n               Landlord has actual data.<\/p>\n<p>          If Landlord shall exercise such right, the amount of Yearly Rent<br \/>\npayable hereunder shall be commensurately adjusted to reflect such change in<br \/>\nOperating Costs in the Base Year and in Tax Base.<\/p>\n<p>     C.   DISPUTE AS TO FAIR MARKET RENTAL VALUE<\/p>\n<p>          Landlord shall initially designate Fair Market Rental Value and<br \/>\nLandlord shall furnish data in support of such designation. If Tenant disagrees<br \/>\nwith Landlord&#8217;s designation of a Fair Market Rental Value, Tenant shall have the<br \/>\nright, by written notice given within thirty (30) days after Tenant has been<br \/>\nnotified of Landlord&#8217;s designation, to submit such Fair Market Rental Value to<br \/>\narbitration.

The unanimous written decision of the<br \/>\ntwo first chosen, without selection and participation of a third arbitrator, or<br \/>\notherwise, the written decision of a majority of three arbitrators chosen and<br \/>\nselected as aforesaid, shall be conclusive and binding upon Landlord and Tenant.<br \/>\nLandlord and Tenant shall each notify the other of its chosen arbitrator within<br \/>\nten (10) days following the call for arbitration and, unless such two<br \/>\narbitrators shall have reached a unanimous decision within thirty (30) days<br \/>\nafter their designation, they shall so notify the President of the Boston Bar<br \/>\nAssociation (or such organization as may succeed to said Boston Bar Association)<br \/>\nand request him to select an impartial third arbitrator, who shall be a real<br \/>\nestate broker with at least ten (10) years&#8217; experience dealing with like types<br \/>\nof properties in the Cambridge office market, to determine Fair Market Rental<br \/>\nValue as herein defined. Such third arbitrator and the first two chosen shall,<br \/>\nsubject to commercial arbitration rules of the American Arbitration Association,<br \/>\nhear the parties and their evidence and render their decision within thirty (30)<br \/>\ndays following the conclusion of such hearing and notify Landlord and Tenant<br \/>\nthereof. Landlord and Tenant shall bear the expense of the third arbitrator (if<br \/>\nany) equally. The decision of the arbitrator shall be binding and conclusive,<br \/>\nand judgment upon the award or decision of the arbitrator may be entered in the<br \/>\nappropriate court of law (as identified on Exhibit 1); and the parties consent<br \/>\nto the<\/p>\n<p>                                      -87-<br \/>\n   96<\/p>\n<p>jurisdiction of such court and further agree that any process or notice of<br \/>\nmotion or other application to the Court or a Judge thereof may be served<br \/>\noutside the State wherein the Building is situated by registered mail or by<br \/>\npersonal service, provided a reasonable time for appearance is allowed. If the<br \/>\ndispute between the parties as to a Fair Market Rental Value has not been<br \/>\nresolved before the commencement of Tenant&#8217;s obligation to pay rent based upon<br \/>\nsuch Fair Market Rental Value, then Tenant shall pay Yearly Rent and other<br \/>\ncharges under the Lease in respect of the Premises in question based upon the<br \/>\nrate in effect immediately before the commencement of Tenant&#8217;s obligation to pay<br \/>\nrent based upon such Fair Market Rental Value until either the agreement of the<br \/>\nparties as to the Fair Market Rental Value, or the decision of the arbitrators,<br \/>\nas the case may be, at which time Tenant shall pay any underpayment of rent and<br \/>\nother charges to Landlord, or Landlord shall refund any overpayment of rent and<br \/>\nother charges to Tenant, in either case with interest at the rate set forth in<br \/>\nArticle 6 hereof.<\/p>\n<p>4.
