(a)Subtenant hereby grants to Sublandlord an exclusive license to use and occupy the areas (totaling approximately 2,000 square feet) designated as “Licensed Office Space” on Exhibit A (the “Licensed Office Space”) for office purposes by no more than five (5) of Sublandlord’s employees (the “Exact Employees”), for the period commencing on the Term Commencement Date, and ending on July 31, 2010, (the “Office License Term”), on and subject to the following terms and conditions:  (i) Sublandlord shall be permitted to keep in the Licensed Office Space, desks, chairs, office equipment and supplies belonging to Sublandlord for up to five (5) employees together with dedicated telephone, facsimile, and internet service for said employees; (ii) Sublandlord shall be permitted to keep computers in the IT closet, and Sublandlord and/or its external information technology service personnel shall have non-exclusive access to said computers at all times by way of badge access, and Sublandlord will provide monthly reports to Subtenant showing which individuals had access to the IT closet; (iii) Subtenant shall be permitted non-exclusive access to the portion of the Premises which will enable Sublandlord’s employees and guests and other invitees to use the restrooms during the Office License Term; (iv) the Exact Employees and any of their guests, invitees, and agents shall have the non-exclusive right to travel to and from the Licensed Office Space and the Common Areas through the area shown as “Lobby Area” on Exhibit A attached hereto; (v) the Licensed Office Space shall include a dedicated conference room and some reasonable storage space; (vi) Sublandlord shall have the right to use five (5) parking spots adjacent to the Building; and (vii) Sublandlord shall have badge access to the Licensed Office Space, but Subtenant shall not have access to the Licensed Office Space provided, however, that Subtenant and Sublandlord (and Overlandlord) shall have access to any portion of the Premises (including any licensed space) for emergency purposes.  The parties agree that Subtenant shall install the wall shown as “Dividing Wall” on Exhibit A-1 attached hereto and the door shown as “Internal Door” on Exhibit A-1, promptly following the Term Commencement Date.  The license described in this Section 30(a) shall terminate upon either (x) a termination of the Overlease, or (y) a default by Sublandlord under this Sublease, provided that Subtenant shall have delivered written notice of such default to Sublandlord and Sublandlord shall have failed to cure said default within ten (10) business days of delivery of such notice.

(b)Subtenant also grants to Sublandlord an exclusive license for the use and occupancy of that portion of the Premises shown as “Freezer Farm” on the attached Exhibit A (the “Freezer Farm”) for the purpose of storing and utilizing the freezers located therein (the “Freezers”), until the later to occur of: (i) December 31, 2008 or (ii) the date on which Sublandlord has vacated the Freezer Farm entirely including removal of all equipment therefrom and has delivered same to Subtenant in broom clean condition and Sublandlord has performed all obligations required of it to be performed under Section 29.31.7 of the Overlease (the “Freezer Farm Vacate Date”).  Sublandlord shall remove the Freezers in accordance with all applicable

federal, state, or local laws or regulations, by no later than December 31, 2008, but shall have until January 15, 2009 to complete its obligations under Section 29.31.7 of the Overlease with respect to the Freezer Farm and shall provide copies of the de-commissioning certificate and any reports related thereto to Subtenant and Overlandlord promptly after receipt.  Sublandlord will use commercially reasonable efforts to remove the Freezers by December 15, 2008, but Sublandlord’s failure to remove said Freezers by December 15, 2008 shall not be a breach of, or default under, this Sublease.  Notwithstanding any provision contained herein to the contrary, Sublandlord shall pay Subtenant a penalty of $500.00 per day for each day beyond January 15, 2009, which elapses without the conditions set forth in clause (ii) of this Section 30(b) having been met, and Subtenant shall be entitled to deduct the accrued and unpaid dollar amount of such penalty from each payment of Monthly Base Rent due from Subtenant to Sublandlord hereunder provided that in no event shall such penalty exceed the cost of removing the Freezers and complying with the obligations under Section 29.31.7 of the Overlease.  In the event that Sublandlord has failed to remove the Freezers from the Freezer Farm by January 15, 2009, then Subtenant shall enter the Freezer Farm and remove the Freezers, provided Subtenant uses reasonable care and does not commit waste in so doing.  In the event Subtenant performs the removal obligations as set forth herein, Subtenant shall do so in accordance with Sections 15.2 and 29.31.7 of the Overlease, as modified by the terms herein.  In the event that any environmental contamination created or caused by Sublandlord’s possession or use of the Premises (the “Contamination”) is discovered during Subtenant’s performance of the obligations of this Section 30, Overlandlord and Sublandlord shall hold Subtenant harmless and shall release Subtenant from all liability created or caused by the Contamination.  Subtenant shall be responsible for payment of up to $35,000 for costs associated with the performance of the obligations set forth above (“Subtenant’s Contribution”), with the exception of damage to the Premises or the Property caused by Subtenant’s removal of the Freezers from the Freezer Farm for which Subtenant shall remain responsible for restoration of any such damage.  In the event Overlandlord is unable to cause Sublandlord to perform its obligations under the Overlease, Overlandlord shall remediate the Premises, including any Contamination, but hereby reserves all remedies Overlandlord may have against Sublandlord under all applicable laws.  Subtenant understands that Subtenant’s Initial Alterations as related to the Freezer Farm shall not commence until Sublandlord, Subtenant, and/or Overlandlord has performed, to Overlandlord’s satisfaction, all obligations under section 29.31.7 of the Overlease.  Sublandlord hereby waives any and all rights, to the maximum extent permitted by applicable law, necessary to permit Subtenant to exercise its rights to remove the Freezers set forth in this Section 30(b).

31.Bankruptcy Provisions.  Sublandlord shall immediately notify Subtenant in the event that Sublandlord files for bankruptcy, and Sublandlord hereby authorizes Subtenant to file pleadings in any such bankruptcy on behalf of Subtenant.

32.Confidential Information. Sublandlord and Subtenant acknowledge and agree that during the course of this Sublease each party may disclose to the other, intentionally or unintentionally, by act or omission, certain confidential, technical and business information which the disclosing party desires the receiving party to treat as “Confidential Information”, as defined below, and that both Sublandlord and Subtenant may be a disclosing party or a receiving party of such Confidential Information, as defined below.  As used herein, the term “Confidential Information” shall mean any information disclosed previously or in the future by either party to

the other party, either directly or indirectly, in writing, orally or by inspection of tangible objects (including without limitation documents, prototypes, samples, plans and equipment), which is designated, orally or in writing, as “Confidential,” “Proprietary” or some similar designation. Confidential Information may also include information disclosed to a disclosing party by third parties.  Confidential Information shall not, however, include any information which (a) at the time of disclosure is, or thereafter becomes, through no act or failure to act on the receiving party’s part, published information generally known on a non-confidential basis in the parties’ industry; (b) becomes publicly known and made generally available after disclosure by the disclosing party to the receiving party through no action or inaction of the receiving party; (c) corresponds in substance to that developed by the receiving party and is already in the possession of the receiving party prior to the time of disclosure by the disclosing party as shown by the receiving party’s files and records; (d) corresponds in substance to information that is obtained by the receiving party from a third party without a breach of such third party’s obligations of confidentiality; (e) is independently developed by the receiving party without use of or reference to the disclosing party’s Confidential Information, as shown by documents and other competent evidence in the receiving party’s possession; or (f) is required by law, court order or other governmental order or request to be disclosed by the receiving party, provided that the receiving party gives the disclosing party prompt written notice of such requirement prior to such disclosure and reasonable assistance in obtaining an order protecting the information from public disclosure, and uses all reasonable efforts to limit the disclosure and maintain the confidentiality of the information to the extent possible.

33.Non-Use and Non-Disclosure.  Each party agrees not to use any Confidential Information of the other party for any purpose whatsoever except as contemplated by this Sublease.  Each party agrees not to disclose any Confidential Information of the other party to third parties or to its employees, except to those employees of the receiving party who are permitted to use the Premises hereunder.  Both parties agree not to reverse engineer, disassemble or decompile any prototypes, software or other tangible objects which embody the other party’s Confidential Information and which are provided to the party hereunder.

34.Maintenance of Confidentiality.  Each party agrees to take reasonable measures to protect the secrecy of and avoid disclosure and unauthorized use of the Confidential Information of the other party.  Without limiting the foregoing, each party agrees to take at least those measures that it takes to protect its own most highly confidential information and to ensure that its employees who have access to Confidential Information of the other party have signed a non-use and non-disclosure agreement with provisions containing content similar to the non-use and non-disclosure provisions hereof, prior to any disclosure of Confidential Information to such employees.  Without limiting the generality of the foregoing, (a) Sublandlord shall ensure that the Exact Employees have all signed the type of non-use and non-disclosure agreement described in the foregoing sentence (the “Non-Disclosure Agreements”) prior to the Term Commencement Date, and any third party information technology service personnel and/or any auditing personnel who will have access to the Premises shall sign Non-Disclosure Agreements, to the extent their employers allow or approve of such Non-Disclosure Agreements, prior to being given such access, and (b) Subtenant shall ensure that all of Subtenant’s employees who will have access to the Premises shall have signed Non-Disclosure Agreements prior to such employees commencing work at the Premises.  The parties agree not to make any copies of the

Confidential Information of the other party unless the same are previously approved in writing by the other party.  Each party agrees to reproduce the other party’s proprietary rights notices on any such approved copies, in the same manner in which such notices were set forth in or on the original.

35.Hazardous Materials.  Sublandlord and Subtenant agree as follows with respect to the existence or use of “Hazardous Material” in or on the Premises or Project.

(a)Subtenant, at its sole cost and expense, shall comply with all laws, statutes, ordinances, rules and regulations of any local, state or federal governmental authority (including, without limitation, the Fire Department of the City of Marlborough, and the Local Emergency Planning Committee, if any) having jurisdiction concerning environmental, health and safety matters (collectively, “Environmental Laws”), including, but not limited to, any discharge into the air, surface, water, sewers, soil or groundwater of any Hazardous Material (as defined in Section 35(c), below), whether within or outside the Premises, within the Project.  Notwithstanding the foregoing, nothing contained in this Sublease requires, or shall be construed to require, Subtenant to incur any liability related to or arising from environmental conditions (except to the extent set forth in Section 4.2.3(V) of the Overlease): (i) for which the Sublandlord is responsible pursuant to the  express terms of the Overlease, (ii) which existed within the Premises or the Project prior to the date Subtenant takes possession of the Premises pursuant to this Sublease, or which result from Sublandlord’s use or occupancy as contemplated by Section 30 of this Sublease subsequent to the Term Commencement Date, (iii) which are unrelated to the acts or omissions of Subtenant, its employees, officers, contractors, representatives or agents (individually and/or collectively, “Tenant Party”), or (iv) which were caused solely by a third party which is not a Tenant Party.

(b)Subtenant shall not cause or permit any Hazardous Material to be brought upon, handled, kept, stored or used in or about the Premises or otherwise in the Project by Subtenant, its agents, employees, contractors or invitees, except for Hazardous Materials which are typically used in the operation of offices, and except for Hazardous Material which are used by Subtenant in connection with the Permitted Use and which are specifically identified by name and acceptable quantity on Exhibit C attached hereto, provided that all such materials are stored, used and disposed of in strict compliance with all applicable Environmental Laws and with good scientific and medical practice, and provided further that all such materials shall be removed from the Premises and the Project prior to the expiration or earlier termination of this Sublease in accordance with all applicable laws at the sole cost and expense of Subtenant.  Subject to the provisions of this Section 35, Subtenant shall update Overlandlord in writing with any requested increases in quantity, changes and/or additions to Exhibit C (the “New Materials”) made after the date of this Sublease, and subject to the provisions of this Section 35, the update shall be deemed to be incorporated into Exhibit C if Overlandlord provides its written approval of Subtenant’s use of the New Materials, a copy of which approval Subtenant shall provide to Sublandlord.  If Overlandlord shall fail to provide its written approval of the New Materials, at Subtenant’s reasonable request, Overlandlord and Subtenant shall meet to determine what protocols Subtenant may institute in order to satisfy any concerns raised by Overlandlord, and Subtenant shall either (i) implement any such protocols reasonably suggested by Overlandlord and/or Overlandlord’s consultants, or (ii) not utilize the particular New Material(s) to which

Overlandlord has objected and ensure the same do not enter the Premises and the Project.  Notwithstanding anything to the contrary,  Subtenant  shall not cause or permit any radioactive materials or radioactive isotopes to be brought upon, handled, kept, stored or used in or about the Premises or otherwise in the Project by Subtenant, its agents, employees, contractors or invitees without the prior written consent of Overlandlord.  Notwithstanding the foregoing, with respect to any of Subtenant’s Hazardous Material which Subtenant does not properly handle, store or dispose of in compliance with all applicable Environmental Laws and good scientific and medical practice, Subtenant shall, upon written notice from Overlandlord, no longer have the right to bring such material into the buildings or the Project until Subtenant has demonstrated, to Overlandlord’s reasonable satisfaction, that Subtenant has implemented programs to thereafter properly handle, store or dispose of such material.

(c)As used herein, the term “Hazardous Material” means any flammable substances, explosives, and radioactive materials,  and any hazardous or toxic substance, material or waste or petroleum derivative which is or becomes regulated by any Environmental Law, specifically including live organisms, viruses and fungi, medical waste, and so-called “biohazard” materials.  The term “Hazardous Material” includes, without limitation, any material or substance which is (i) designated as a “hazardous substance” pursuant to Section 1311 of the Federal Water Pollution Control Act (33 U.S.C. Section 1317), (ii) defined as a “hazardous waste” pursuant to Section 1004 of the Federal Resource Conservation and Recovery Act, 42 U.S.C. Section 6901 et seq. (42 U.S.C. Section 6903), (iii) defined as a “hazardous substance” pursuant to Section 101 of the Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. Section 9601 et seq. (42 U.S.C. Section 9601), (iv) defined as “hazardous substance” or “oil” under Chapter 21E of the General Laws of Massachusetts, or (v) a so-called “biohazard” or medical waste, or is contaminated with blood or other bodily fluids; and “Environmental Laws” include, without limitation, the laws listed in the preceding clauses (i) through (iv).

(d)Any increase in the premium for necessary insurance on the Premises or the Project which arises from Subtenant’s use and/or storage of these Hazardous Materials shall be solely at Subtenant’s expense.  Subtenant shall procure and maintain at its sole expense such additional insurance as may be necessary to comply with any requirement of any Federal, State or local government agency with jurisdiction.

(e)Subtenant hereby covenants and agrees to indemnify, defend and hold Sublandlord and Overlandlord harmless from any and all claims, judgments, damages, penalties, fines, costs, liabilities or losses (collectively “Losses”) which Sublandlord or Overlandlord may reasonably incur arising out of contamination of real estate, the Premises, the Project, or other property not a part of the Premises, which contamination arises as a result of: (i) the presence of Hazardous Material in the Premises or the Project, the presence of which is caused or permitted by Subtenant, its agents, employees, contractors or invitees, or (ii) from a breach by Subtenant of its obligations under this Section 35; provided that, notwithstanding the foregoing or any other provision contained in this Sublease to the contrary, Subtenant shall have no liability for any Losses which Sublandlord or Overlandlord may incur now or hereafter arising from Sublandlord’s use and occupancy of the Premises and the Project or performance of any of its obligations under the terms of the Overlease or hereunder (unless otherwise set forth herein).  This indemnification of Sublandlord and Overlandlord by Subtenant includes, without limitation,

reasonable costs incurred in connection with any investigation of site conditions or any cleanup, remedial, removal or restoration work required by any federal, state or local governmental agency or political subdivision because of Hazardous Material present in the soil or ground water on or under the Premises based upon the circumstances identified in the first sentence of this Section 35(e).  The indemnification and hold harmless obligations of Subtenant under this Section 35(e) shall survive any termination of this Sublease.  Without limiting the foregoing, if the presence of any Hazardous Material in the buildings or otherwise in the Project caused or permitted by Subtenant results in any contamination of the Premises, Subtenant shall give immediate notice thereof to Overlandlord and Sublandlord and shall promptly take all actions at its sole expense as are necessary to return the Premises to a condition which complies with all Environmental Laws; provided that Overlandlord’s approval of such actions shall first be obtained, which approval shall not be unreasonably withheld so long as such actions, in Overlandlord’s reasonable discretion, would not potentially have any materially adverse long-term or short-term effect on the Premises, and, in any event, Overlandlord shall not withhold its approval of any proposed actions which are required by applicable Environmental Laws.  Notwithstanding anything to the contrary in the Sublease contained, the foregoing indemnity shall not apply to: (i) any Hazardous Materials which exist in the Premises or elsewhere in the Project prior to and as of the execution date of this Sublease, or (ii) any Hazardous Materials introduced to the Project by other tenants within their respective premises, or (iii) any Hazardous Materials the presence of which were not caused or permitted by the acts or omissions of Subtenant, its employees, agents, consultants and/or contractors.

(f)Notwithstanding anything to the contrary in this Lease, if Subtenant fails to cure any breach or default of this Section 35 within five (5) business days after written notice from Sublandlord (or if such default cannot be cured within said five day period, to commence to cure said period during said five day period and diligently proceed to cure such default within thirty (30) days), such failure shall constitute a default under this Sublease, and in the event of such a default, in addition to any other remedies available to Sublandlord under this Sublease, Sublandlord may terminate this Sublease upon ten (10) days written notice to  Subtenant.

(g)Subtenant shall, after Subtenant, and anyone claiming by, through or under Subtenant, vacate the Premises, and immediately prior to the time that Subtenant  delivers the Premises to Overlandlord:  (i) cause the Premises to be decommissioned in accordance with the regulations of the U.S. Nuclear Regulatory Commission and/or the Massachusetts Department of Public Health for the control of radiation; (ii) provide a written report by a licensed industrial hygienist or equivalent to confirm that the Premises contain no contaminants per the National Institute of Health (or its successor organization) rules and regulations on bio-safety as administered by the Department of Health; and (iii) provide a copy of its most current chemical waste removal manifest and a certification from an officer of  Subtenant that no chemicals remain in the Premises.

(h)Overlandlord and Sublandlord shall have the right from time to time to conduct (or retain one or more consultants to conduct) environmental audits of the Premises to ensure and verify Subtenant’s compliance with this Section 35, upon three (3) business days advance written notice to Subtenant.  Subtenant agrees to cooperate with the person or entity conducting said audit and to supply all information reasonably requested in connection therewith.  Subtenant shall pay the cost of such audit if such audit discloses that Subtenant has

materially violated any of the provisions of this Section 35;  otherwise, the cost of said audit shall be paid for by Overlandlord.

(i)Subtenant shall not dispose of any Hazardous Materials at the Project (including, without limitation, placing, or permitting any Hazardous Materials to be placed into the sewer system servicing the Project), except as permitted by law in approved and environmentally safe containers which Subtenant will dispose of off-site.  Subtenant shall give Overlandlord written notice annually (and from time to time, if changed) of the name, address and telephone number of the contractor that will be responsible for removal of all Hazardous Materials disposed of by Subtenant from the Premises and/or the Project.

(j)Subtenant shall provide Overlandlord with a copy of its Chemical Hygiene Plan (as set forth in OSHA 1910.1450) annually, or more often as and when it is amended.
