The failure to have such Portion of the Premises ready for<br \/>\nTenant&#8217;s occupancy on the Specified Commencement Date in respect of such Portion<br \/>\nshall in no way affect the validity of this Lease or the obligations of Tenant<br \/>\nhereunder nor shall the same be construed in any way to extend the term of this<br \/>\nLease. If a Portion of the Premises is not ready for Tenant&#8217;s occupancy within<br \/>\nthe meaning of Article 4.2 hereof on the Specified Commencement Date for such<br \/>\nPortion, Tenant shall not have any claim against Landlord, and Landlord shall<br \/>\nhave no liability to Tenant, by reason thereof. In addition, Landlord shall use<br \/>\nreasonable efforts to have the lockers and showers shown on Plan A5-1, Enlarged<br \/>\nBasement Core Plan, dated May 10, 1999, as modified by Plan SKA031 dated August<br \/>\n31, 1999, both prepared by Sasaki Associates in association with DTS Shaw, Inc.,<br \/>\ncompleted, at Landlord&#8217;s expense, by the Specified Commencement Date in respect<br \/>\nof Portion A, but Landlord&#8217;s failure so to do shall not affect the Term<br \/>\nCommencement Date in respect of Portion A.<\/p>\n<p>         (b) Notwithstanding anything to the contrary herein contained, if the<br \/>\nTerm Commencement Date in respect of either Portion of the Premises has not<br \/>\noccurred on or before the date (&#8220;Initial Target Date&#8221;) sixty (60) days after the<br \/>\nSpecified Commencement Date in respect of such Portion, then Tenant shall be<br \/>\nentitled to a credit against the Yearly Rent otherwise payable in respect of<br \/>\nsuch Portion from and after the Term Commencement Date in respect of such<br \/>\nPortion equal to the amount of Yearly Rent payable in respect of such Portion<br \/>\nfor one (1) day for each day between the Initial Target Date and the Term<br \/>\nCommencement Date in respect of such Portion, provided however, that the Initial<br \/>\nTarget Date shall be extended by the number of days that Landlord&#8217;s Work in<br \/>\nrespect of such Portion is delayed due to Force Majeure Delays.<\/p>\n<p>         (c) Notwithstanding the foregoing, if the Term Commencement Date in<br \/>\nrespect of Portion A shall not have occurred on or before the Outside Target<br \/>\nDate, as hereinafter defined, then Tenant shall have the right, exercisable by a<br \/>\nwritten thirty (30) day termination notice given on or after the Outside Target<br \/>\nDate, to terminate the Lease. If the Term Commencement Date in respect of<br \/>\nPortion A occurs on or before the thirtieth (30th) day after Landlord receives<br \/>\nsuch termination notice, Tenant&#8217;s termination notice shall be deemed to be void<br \/>\nand of no force or effect. If the Term Commencement Date in respect of Portion A<br \/>\ndoes not occur on or before such thirtieth (30th) day, this Lease shall<br \/>\nterminate and shall be of no further force or effect. For the purposes hereof,<br \/>\nthe &#8220;Outside Target Date&#8221; shall be defined as the date ninety (90) days after<br \/>\nthe Specified Commencement Date in respect of Portion A, provided however, that<br \/>\nthe Outside Target Date shall be extended by the lesser of (i) the length of any<br \/>\ndelays in Landlord&#8217;s Work in respect of Portion A arising from Force Majeure<br \/>\nDelays, and (ii) ninety (90) days.<\/p>\n<p>         4.2      WHEN PREMISES DEEMED READY.<\/p>\n<p>         (a) Definition of Substantially Completed. Each Portion of the Premises<br \/>\nshall be conclusively deemed ready for Tenant&#8217;s occupancy as soon as (i)<br \/>\nLandlord&#8217;s Work, as hereinafter defined, in such Portion has been substantially<br \/>\ncompleted by Landlord insofar as is practicable in view of Tenant Delays and the<br \/>\nelevator, plumbing, air conditioning and electric facilities are substantially<br \/>\navailable to Tenant, and in good working order, in accordance with the<br \/>\nobligations assumed by Landlord hereunder and (ii) the City of Cambridge shall<br \/>\nhave issued a permanent, unconditional certificate of occupancy, or its<br \/>\nequivalent, permitting Tenant to legally occupy such Portion of the Premises.<br \/>\nLandlord&#8217;s Work shall be defined as the work to be performed by Landlord in<br \/>\npreparing each Portion of the Premises for Tenant&#8217;s occupancy as shown on<br \/>\nTenant&#8217;s final approved plans in respect of such Portion of the Premises,<br \/>\nprovided however, that if Landlord&#8217;s Work in respect of any Portion of the<br \/>\nPremises is delayed as the result of any Tenant Delays, then such Portion shall<br \/>\nbe deemed to be ready for Tenant&#8217;s occupancy as of date that such Portion would<br \/>\nhave been substantially completed but for such Tenant Delays. Notwithstanding<br \/>\nthe foregoing, if Tenant engages its own contractors to perform any portion of<br \/>\nthe work to be performed in the initial preparation of such Portion of the<br \/>\nPremises, Landlord shall be relieved of its responsibility for obtaining such<br \/>\ncertificate of occupancy to the extent that Landlord&#8217;s failure to obtain such<br \/>\ncertificate of occupancy is based upon any aspect of the work performed by<br \/>\nTenant&#8217;s contractors. A<\/p>\n<p>                                      -3-<br \/>\n   13<br \/>\nPortion of the Premises shall not be deemed to be unready for Tenant&#8217;s occupancy<br \/>\nor incomplete if only minor or insubstantial details of construction, decoration<br \/>\nor mechanical adjustments remain to be done in such Portion of the Premises or<br \/>\nany part thereof which will not materially interfere with Tenant&#8217;s conduct of<br \/>\nbusiness in such Portion of the Premises. If a Portion of the Premises is deemed<br \/>\nready for Tenant&#8217;s occupancy, pursuant to the foregoing, (and the term shall<br \/>\nhave commenced by reason thereof), but such Portion of the Premises is not in<br \/>\nfact actually ready for Tenant&#8217;s occupancy, Tenant shall not (except with<br \/>\nLandlord&#8217;s consent) be entitled to take possession of such Portion of the<br \/>\nPremises for use as set forth in Exhibit 1 until such Portion of the Premises is<br \/>\nin fact actually ready for such occupancy. Landlord&#8217;s architect&#8217;s certificate of<br \/>\nsubstantial completion, as hereinabove stated, given in good faith, or of any<br \/>\nother facts pertinent to this Article 4.2 shall be deemed conclusive of the<br \/>\nstatements therein contained and binding upon Tenant. Any of Landlord&#8217;s Work in<br \/>\na Portion of the Premises not fully completed on the Term Commencement Date in<br \/>\nrespect of such Portion shall be so completed by Landlord within thirty (30)<br \/>\ndays after the Term Commencement Date in respect of such Portion (other than<br \/>\nlong-lead items which shall be completed with reasonable diligence by Landlord).<\/p>\n<p>         (b) Definition of Tenant Delays. For the purposes hereof, a &#8220;Tenant<br \/>\nDelay&#8221; shall be defined as a delay in the performance of Landlord&#8217;s Work: (i)<br \/>\ndue to special work (i.e., long &#8211; lead items of which Landlord advises Tenant at<br \/>\nthe time Landlord approves Tenant&#8217;s final plans in respect of a Portion of the<br \/>\nPremises), changes, alterations or additions required or made by Tenant in the<br \/>\nlayout or finish of either Portion of the Premises or any part thereof, (ii)<br \/>\ncaused in whole or in part by Tenant through the delay of Tenant in submitting<br \/>\nany plans and\/or specifications, supplying information, approving plans,<br \/>\nspecifications or estimates, giving authorizations or otherwise or (iii) caused<br \/>\nin whole or in part by delay and\/or default on the part of Tenant or its<br \/>\ncontractors including, without limitation, the utility companies and other<br \/>\nentities furnishing communications, data processing or other service or<br \/>\nequipment.<\/p>\n<p>         4.3 PLANS AND SPECIFICATIONS. Tenant shall be solely responsible for<br \/>\nthe timely preparation and submission to Landlord of the final architectural,<br \/>\nelectrical and mechanical construction drawings, plans and specifications<br \/>\n(called &#8220;plans&#8221;) necessary to construct each Portion of the Premises for<br \/>\nTenant&#8217;s occupancy, which plans shall be subject to approval by Landlord&#8217;s<br \/>\narchitect and engineers, which approval shall not be unreasonably withheld, and<br \/>\nshall comply with their requirements to avoid aesthetic or other conflicts with<br \/>\nthe design and function of the balance of the Building.

Without limiting the foregoing, Tenant shall be responsible<br \/>\nfor all elements of the design of Tenant&#8217;s plans (including, without limitation,<br \/>\ncompliance with law, functionality of design, the structural integrity of the<br \/>\ndesign, the configuration of each Portion of the Premises and the placement of<br \/>\nTenant&#8217;s furniture, appliances and equipment), and Landlord&#8217;s approval of<br \/>\nTenant&#8217;s plans shall in no event relieve Tenant of the responsibility for such<br \/>\ndesign. Tenant has assured itself by direct communication with the architect and<br \/>\nengineers (Landlord&#8217;s or its own, as the case may be) that the final approved<br \/>\nplans can be delivered to Landlord on or before the Final Plans Date in respect<br \/>\nof each Portion of the Premises as stated in Exhibit 1, provided that Tenant<br \/>\npromptly furnishes complete information concerning its requirements to said<br \/>\narchitect and engineers as and when requested by them; and Tenant covenants and<br \/>\nagrees to cause said final, approved plans and specifications to be delivered to<br \/>\nLandlord on or before said respective Final Plans Dates and to devote such time<br \/>\nas may be necessary in consultation with said architect and engineers to enable<br \/>\nthem to complete and submit all plans within the required time limit. Time is of<br \/>\nthe essence in respect of preparation and submission of plans by Tenant. (The<br \/>\nword &#8220;architect&#8221; as used in this Article 4 shall include an interior designer or<br \/>\nspace planner.)<\/p>\n<p>         4.4 PREPARATION OF PREMISES.<\/p>\n<p>                  (a) By Landlord.

Notwithstanding the foregoing, overtime costs and costs<br \/>\nresulting from the negligence of the Landlord or its contractors shall not be<br \/>\ncharged against Landlord&#8217;s Contribution. Tenant shall, within thirty (30) days<br \/>\nof billing therefor, together with reasonable backup to evidence such costs,<br \/>\nreimburse Landlord for all costs of Landlord&#8217;s Work in excess of Landlord&#8217;s<br \/>\nContribution. Tenant shall have the right to apply any unused portion of<br \/>\nLandlord&#8217;s Contribution towards (i) the architectural and engineering fees<br \/>\nincurred by Tenant in connection with Landlord&#8217;s Work, and (ii) the generator to<br \/>\nbe installed by Tenant at the Premises. Landlord shall reimburse Tenant for such<br \/>\nunused portion of Landlord&#8217;s Contribution within thirty (30) days after<br \/>\nLandlord&#8217;s receipt of paid invoices evidencing such costs. Except as set forth<br \/>\nin the immediately preceding two (2) sentences, Tenant shall have no right to<br \/>\nuse any unused portion of Landlord&#8217;s Contribution.<\/p>\n<p>                  (b) By Tenant. Subject always to the provisions of Articles<br \/>\n4.2 and 4.3, if Tenant will be employing any contractors in preparing either<br \/>\nPortion of the Premises for Tenant&#8217;s occupancy, Landlord will give Tenant<br \/>\nreasonable advance notice of the date on which such Portion of the Premises will<br \/>\nbe ready for such other contractors and a reasonable time will be allowed from<br \/>\nsuch date for doing the work to be performed by such other contractors.<\/p>\n<p>                  (c) If any work, including but not by way of limitation,<br \/>\ninstallation of built-in equipment by the manufacturer or distributor thereof,<br \/>\nshall be performed by contractors not employed by Landlord, Tenant shall take<br \/>\nnecessary reasonable measures to the end that such contractor shall cooperate in<br \/>\nall ways with Landlord&#8217;s contractors to avoid any delay to the work being<br \/>\nperformed by Landlord&#8217;s contractors or conflict in any other way with the<br \/>\nperformance of such work.<\/p>\n<p>         4.5 QUALITY AND COST OF MATERIALS.

In the event of a Tenant Delay,<br \/>\nany additional cost to Landlord in connection with the completion of each<br \/>\nPortion of the Premises in accordance with the terms of this Lease and Exhibit 4<br \/>\nshall be promptly paid by Tenant to Landlord if such additional cost is in whole<br \/>\nor in part the result of such failure, omission or delay of Tenant (provided<br \/>\nhowever, that if Tenant is only partially responsible for a delay, i.e. because<br \/>\nof delay caused by Landlord or Landlord&#8217;s contractor, Tenant shall be charged<br \/>\nfor additional costs only to the extent of Tenant&#8217;s partial responsibility). For<br \/>\nthe purposes of the next preceding sentence, the expression &#8220;additional cost to<br \/>\nLandlord&#8221; shall mean the actual, out-of-pocket cost over and above such cost as<br \/>\nwould have been the aggregate cost to Landlord of completing such Portion of the<br \/>\nPremises in accordance with the terms of<\/p>\n<p>                                      -5-<br \/>\n   15<br \/>\nthis Lease and Exhibit 4 had there been no such Tenant Delay.

Tenant agrees to reimburse Landlord for the<br \/>\namount of such costs (if any), as reasonably determined by Landlord, due to a<br \/>\nPremises population in excess of the foregoing maximum.<\/p>\n<p>9.

Without limiting the foregoing, Landlord shall assign its right<br \/>\nto Tenant against any such contractor and\/or material supplier, if necessary to<br \/>\nenable Tenant to prosecute its claim against any such contractor and\/or material<br \/>\nsupplier.<\/p>\n<p>         15.6 REPAIRS AND ALTERATIONS&#8211;NO DIMINUTION OF RENTAL VALUE.

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<br \/>\nhereinafter provided for, this Lease is subject and subordinate in all respects<br \/>\nto all matters of record (including, without limitation, deeds and land<br \/>\ndisposition agreements), ground leases and\/or underlying leases, and all<br \/>\nmortgages, any of which may now or hereafter be placed on or affect such leases<br \/>\nand\/or the real property of which the Premises are a part, or any part of such<br \/>\nreal property, and\/or Landlord&#8217;s interest or estate therein, and to each advance<br \/>\nmade and\/or hereafter 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 lessor&#8217;s right to do<br \/>\nso for, on behalf and in the name of Tenant under certain circumstances, as<br \/>\nhereinafter provided. Tenant acknowledges that, where applicable, any consent or<br \/>\napproval hereafter given by Landlord may be subject to the further consent or<br \/>\napproval of such mortgagee and\/or ground lessor; and the failure or refusal of<br \/>\nsuch mortgagee and\/or ground lessor to give such consent or approval shall,<br \/>\nnotwithstanding anything to the contrary in this Lease contained, constitute<br \/>\nreasonable justification for Landlord&#8217;s withholding its consent or approval.<br \/>\nLandlord hereby represents to Tenant that, as of the Execution Date of this<br \/>\nLease, there is no mortgage affecting the Premises or the<\/p>\n<p>                                      -41-<br \/>\n   51<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<br \/>\nsubordinate or revoke any such subordination of the mortgage or ground lease<br \/>\nheld by it to this Lease. Such subordination or revocation, as the case may be,<br \/>\nshall be effected 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 security deposit unless it shall<br \/>\nhave been paid over or physically delivered to such successor; or (iv) be bound<br \/>\nby any previous modification of this Lease or by any previous payment of Yearly<br \/>\nRent for a period greater than one (1) month, made without such ground lessor&#8217;s<br \/>\nor mortgagee&#8217;s consent where such consent is required by applicable ground lease<br \/>\nor mortgage 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 hereof to execute a<br \/>\nsuitable instrument in confirmation of Tenant&#8217;s agreement to attorn, as<br \/>\naforesaid, subject to Landlord&#8217;s, mortgagee&#8217;s and ground lessor&#8217;s right to do so<br \/>\nfor, on behalf and in the name of Tenant under certain circumstances, as<br \/>\nhereinafter 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;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>                                      -42-<br \/>\n   52<br \/>\n         (f) Notwithstanding anything to the contrary contained in this Article<br \/>\n23, if all or part of Landlord&#8217;s estate and interest in the real property of<br \/>\nwhich the Premises are a part shall be a leasehold estate held under a ground<br \/>\nlease, then: (i) the foregoing subordination provisions of this Article 23 shall<br \/>\nnot apply 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<br \/>\nobserve any agreement by Landlord herein, in no event will the Landlord be<br \/>\ndeemed to be in default under this Lease permitting Tenant to exercise any or<br \/>\nall rights or remedies under this Lease until the Tenant shall have given<br \/>\nwritten notice of such failure to any mortgagee (ground lessor and\/or trustee)<br \/>\nof which Tenant shall have been advised and until a reasonable period of time<br \/>\nshall have elapsed following the giving of such notice, during which such<br \/>\nmortgagee (ground lessor and\/or trustee) shall have the right, but shall not be<br \/>\nobligated, to remedy such failure.<\/p>\n<p>24.      QUIET ENJOYMENT<\/p>\n<p>         Landlord covenants that if, and so long as, Tenant keeps and performs<br \/>\neach and every covenant, agreement, term, provision and condition herein<br \/>\ncontained on the part and on behalf of Tenant to be kept and performed, Tenant<br \/>\nshall quietly enjoy the Premises from and against the claims of all persons<br \/>\nclaiming by, through or under Landlord subject, nevertheless, to the covenants,<br \/>\nagreements, terms, provisions and conditions of this Lease and to the mortgages,<br \/>\nground leases and\/or underlying leases to which this Lease is subject and<br \/>\nsubordinate, as hereinabove set forth.<\/p>\n<p>         Without incurring any liability to Tenant, Landlord may permit access<br \/>\nto the Premises and open the same, whether or not Tenant shall be present, upon<br \/>\nany demand of any receiver, trustee, assignee for the benefit of creditors,<br \/>\nsheriff, marshal or court officer entitled to, or reasonably purporting to be<br \/>\nentitled to, such access for the purpose of taking possession of, or removing,<br \/>\nTenant&#8217;s property or for any other lawful purpose (but this provision and any<br \/>\naction by Landlord hereunder shall not be deemed a recognition by Landlord that<br \/>\nthe person or official making such demand has any right or interest in or to<br \/>\nthis Lease, or in or to the Premises), or upon demand of any representative of<br \/>\nthe fire, police, building, sanitation or other department of the city, state or<br \/>\nfederal governments.<\/p>\n<p>25.

The failure of either party to seek redress for violation,<br \/>\nor to 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<\/p>\n<p>                                      -43-<br \/>\n   53<br \/>\nwith knowledge of the breach of any covenant of this Lease shall not be deemed a<br \/>\nwaiver of such breach. The failure of Landlord to enforce any of such Rules and<br \/>\nRegulations against Tenant and\/or any other tenant in the Building shall not be<br \/>\ndeemed a waiver of any such Rules and Regulations.

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>26.

In each<br \/>\nsuch instance of inability of Landlord to perform, Landlord shall exercise<br \/>\nreasonable diligence to eliminate the cause of such inability to perform.<\/p>\n<p>         Tenant shall neither assert nor seek to enforce any claim against<br \/>\nLandlord, or Landlord&#8217;s agents or employees, or the assets of Landlord or of<br \/>\nLandlord&#8217;s agents or employees, for breach of this Lease or otherwise, other<br \/>\nthan against Landlord&#8217;s interest in the Building of which the Premises are a<br \/>\npart and the Complex and in the uncollected rents, issues and profits thereof,<br \/>\nand Tenant agrees to look solely to such interest for the satisfaction of any<br \/>\nliability of Landlord under this Lease, it being specifically agreed that in no<br \/>\nevent shall Landlord or Landlord&#8217;s agents or employees (or any of the officers,<br \/>\ntrustees, directors, partners, beneficiaries, joint venturers, members,<br \/>\nstockholders or other principals or representatives, and the like, disclosed or<br \/>\nundisclosed, thereof) ever be personally liable for any such liability.

In no event shall Landlord or Landlord&#8217;s agents or employees (or any<br \/>\nof the officers, 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.

SECURITY DEPOSIT<\/p>\n<p>         Tenant acknowledges that Landlord is unwilling to execute the Lease<br \/>\nunless Tenant provides Landlord with security for Tenant&#8217;s obligations under the<br \/>\nLease as follows. Tenant shall have the right to provide such security deposit<br \/>\nby either providing to Landlord a security in accordance with Section I below<br \/>\nor, at Tenant&#8217;s election, a Letter of Credit in accordance with Section II<br \/>\nbelow. Tenant shall have the right to change said election from time to time on<br \/>\nnot less than thirty (30) days&#8217; written notice to Landlord, and Landlord shall,<br \/>\nupon receipt of the replacement form of security deposit in conformance with the<br \/>\nterms hereof, return the original form of security deposit to Tenant.<\/p>\n<p>         I.       SECURITY DEPOSIT<\/p>\n<p>         Tenant shall, at the time that Tenant executes and delivers this Lease<br \/>\nto Landlord, pay to Landlord a security deposit of Two Million and 00\/100<br \/>\nDollars ($2,000,000.00) securing Tenant&#8217;s obligations under this Lease.

In the event that Tenant shall default in any of its<br \/>\nobligations under the Lease, beyond the expiration of applicable notice and<br \/>\ngrace periods, Landlord shall have the right, without prior notice to Tenant, to<br \/>\napply said deposit (or any portion thereof) towards the cure of any such default<br \/>\nand Tenant shall promptly, upon notice from Landlord, pay to Landlord any amount<br \/>\nso applied by Landlord in order to restore the full amount of said deposit. The<br \/>\napplication of all or any part of the deposit to any obligation or default of<br \/>\nTenant under this Lease shall not deprive Landlord of any other rights or<br \/>\nremedies Landlord may have nor shall such application by Landlord constitute a<br \/>\nwaiver by Landlord. The amount of the Security Deposit shall be reduced, and the<br \/>\nexcess thereof refunded to Tenant, if and to the extent that the Tenant would be<br \/>\nentitled to a reduction in the Letter of Credit Amount pursuant to Paragraph II<br \/>\nbelow. Provided that Tenant is not in default of any of its obligations under<br \/>\nthe Lease at the expiration or earlier termination of the term of the Lease,<br \/>\nLandlord shall refund to Tenant any portion of said security deposit which<br \/>\nLandlord is then holding (less the amount determined by Landlord in good faith<br \/>\nto be sufficient to cure any unsatisfied obligation of Tenant) within thirty<br \/>\n(30) days after such expiration or earlier termination of the term. Upon receipt<br \/>\nof all amounts owed under the Lease, Landlord shall promptly return the balance<br \/>\n(if any) of any amounts so<\/p>\n<p>                                      -58-<br \/>\n   68<br \/>\nretained by Landlord in connection with such obligations to Tenant. In addition<br \/>\nto any other deductions Landlord is entitled to make pursuant to the terms<br \/>\nhereof, Landlord shall have the right to make a good faith estimate of any<br \/>\nunreconciled Tax Excess and Operating Expense Excess as of the expiration or<br \/>\nearlier termination of the term of the Lease and to deduct any anticipated<br \/>\nshortfall from the Security Deposit.<\/p>\n<p>                                    or<\/p>\n<p>II.

Letter of Credit Periods<\/p>\n<p>         The &#8220;Initial Period&#8221; shall commence as of the initial Term Commencement<br \/>\nDate in respect of Portion A and shall expire as of the first anniversary of the<br \/>\nTerm Commencement Date in respect of Portion A, provided however, that if (i)<br \/>\nTenant is in monetary or material non-monetary default of any of its obligations<br \/>\nas of the such anniversary, (ii) the Lease is not in full force and effect as of<br \/>\nsuch anniversary, or (iii) as of such anniversary, Tenant has on more than one<br \/>\noccasion previously during the term of the Lease been in monetary or material<br \/>\nnon-monetary default beyond any applicable notice and cure periods (any of (i)<br \/>\nthrough (iii) being referred to as a Failure Condition), the Initial Period<br \/>\nshall expire as of the first day after the first anniversary of the initial Term<br \/>\nCommencement Date in respect of Portion A that no Failure Conditions exist.<\/p>\n<p>         Each successive Period thereafter shall commence as of the day<br \/>\nimmediately following expiration of the immediately preceding Period and,<br \/>\nsubject to the extension of the Period if a Failure Condition exists, shall<br \/>\nexpire as of the next following anniversary of the Term Commencement Date in<br \/>\nrespect of Portion A.<\/p>\n<p>         D.

Tenant may exercise such option to extend by giving Landlord<br \/>\nwritten notice on or before the date twelve (12) months prior to the expiration<br \/>\ndate of the initial term of the Lease. Upon the timely giving of such notice,<br \/>\nthe term of this Lease shall be deemed extended upon all of the terms and<br \/>\nconditions of this Lease, except that Landlord shall have no obligation to<br \/>\nconstruct or renovate the Premises and that the Yearly Rent,<\/p>\n<p>                                      -61-<br \/>\n   71<br \/>\nOperating Costs in the Base Year, and Tax Base during such additional term shall<br \/>\nbe as hereinafter set forth. If Tenant fails to give timely notice, as<br \/>\naforesaid, Tenant shall have no further right to extend the term of this Lease,<br \/>\ntime being of the essence of this Paragraph 2.<\/p>\n<p>         B. Yearly Rent<\/p>\n<p>         The Yearly Rent during the additional term 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, of the Premises then demised to Tenant,<br \/>\nprovided however, that in no event shall the sum of Yearly Rent, Operating<br \/>\nExpense Excess and Tax Excess payable by Tenant for any twelve-(12)- month<br \/>\nperiod during the additional term be less than the sum of Yearly Rent, Operating<br \/>\nExpense 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 fifteen (15)<br \/>\nmonths prior to the expiration date of the initial term of the Lease, to request<br \/>\nin writing that Landlord advise Tenant of Landlord&#8217;s designation of the Fair<br \/>\nMarket Rental Value applicable during the additional term. Landlord shall,<br \/>\nwithin thirty (30) days after receipt of Tenant&#8217;s request, advise Tenant in<br \/>\nwriting of such designation of 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>         If Tenant has exercised its right to extend the term of the Lease in<br \/>\nrespect of said 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 twelve (12) months after Landlord receives such termination notice<br \/>\nfrom Tenant. If Tenant timely exercises such termination right, then: (i) the<br \/>\nYearly Rent payable by Tenant for the period commencing as of the day after the<br \/>\nexpiration of the then current term of the Lease through the effective<br \/>\ntermination date shall be based upon the Fair Market Rental Value, as determined<br \/>\nby the arbitrators or as agreed to by the parties, as the case may be, and (ii)<br \/>\nTenant shall be required to reimburse Landlord, within ten (10) days of billing<br \/>\ntherefor, for any and all reasonable out-of-pocket expenses incurred by Landlord<br \/>\nin connection with the arbitration proceedings; and (iii) Landlord shall have<br \/>\nthe right, by notice (&#8220;Landlord&#8217;s Extension Notice&#8221;) given to Tenant within<br \/>\nthirty (30) days after the receipt of Tenant&#8217;s termination notice, to extend the<br \/>\nTerm of the Lease for a period ending on the date eighteen (18) months after the<br \/>\nexpiration of the Term, prior to any extension pursuant to Paragraph C above<br \/>\n(&#8220;Short Extended Term&#8221;). If Landlord timely gives Landlord&#8217;s Extension Notice,<br \/>\nthen the Term of the Lease shall be automatically extended for the Short<br \/>\nExtended Term and the Yearly Rent during the Short Extended Term shall<\/p>\n<p>                                      -62-<br \/>\n   72<br \/>\nbe based upon the Fair Market Rental Value, as determined by the arbitrators or<br \/>\nas agreed to by the parties, as 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 one (1) additional five (5) year term herein provided.<\/p>\n<p>         E. Notwithstanding the fact that upon Tenant&#8217;s exercise of the herein<br \/>\noption to extend the term of the Lease such extension shall be self-executing,<br \/>\nas aforesaid, the parties shall promptly execute a lease amendment reflecting<br \/>\nsuch additional term after Tenant exercises the herein option, except that the<br \/>\nYearly Rent payable in respect of such additional term, the Operating Costs in<br \/>\nthe Base Year during such additional term, and the Tax Base during such<br \/>\nadditional term, may not be set forth in said amendment. Subsequently, after<br \/>\nsuch Yearly Rent, Operating Costs in the Base Year, and Tax Base are determined,<br \/>\nthe parties shall execute a written agreement confirming the same. The execution<br \/>\nof such lease amendment shall not be deemed to waive any of the conditions to<br \/>\nTenant&#8217;s exercise of its rights under this Paragraph 2, unless otherwise<br \/>\nspecifically provided in such lease amendment.<\/p>\n<p>3.       DEFINITION OF FAIR MARKET RENTAL VALUE<\/p>\n<p>         For the purposes of this Rider:<\/p>\n<p>         A. &#8220;Fair Market Rental Value&#8221; shall be computed as of the date in<br \/>\nquestion at the then current annual rental charge (i.e., the sum of Yearly Rent<br \/>\nplus escalation and other charges), including provisions for subsequent<br \/>\nincreases and other adjustments for leases or agreements to lease then currently<br \/>\nbeing negotiated, or executed in comparable space located in the Complex, or if<br \/>\nno leases or agreements to lease are then currently being negotiated or executed<br \/>\nin the Complex, the Fair Market Rental Value shall be determined by reference to<br \/>\nleases or agreements to lease then currently being negotiated or executed for<br \/>\ncomparable space located elsewhere in first-class office buildings located in<br \/>\nEast Cambridge, Massachusetts. In determining Fair Market Rental Value, the<br \/>\nfollowing factors, among others, shall be taken into account and given effect:<br \/>\nsize, location of Premises, lease term, condition of building, economic<br \/>\nconcessions then being granted by the landlord, the absence of certain costs to<br \/>\nbe incurred by landlord (e.g., brokerage commissions, tenant improvement costs),<br \/>\nand services provided by the landlord.<\/p>\n<p>         B.
