        This SUBLEASE is made as of April 14, 2005, by and between GPC Biotech, Inc., a Delaware corporation having an address at 610 Lincoln Street,
Waltham, Massachusetts 02451 ("Sublessor") and BG Medicine, Inc., a Delaware corporation having an address at 40 Bear Hill Road, Waltham, Massachusetts 02451 ("Sublessee"). 

WITNESSETH:  

        WHEREAS, pursuant to that Lease dated as of March 26, 2001 by and between 610 Lincoln LLC, as landlord ("Prime Lessor") and Sublessor, as tenant (such
lease and all renewals, modifications and extensions thereof are hereinafter collectively referred to as the "Prime Lease"), a true and complete copy of which is attached hereto as  Exhibit A,
 whereby Sublessor leases approximately 85,430 square feet of rentable space on floor(s) one, two and three located in the building
known as and numbered 610 Lincoln Street, Waltham, Massachusetts 02451 (the "Building") (all as more particularly described in the Prime Lease the "Premises"); and 

        WHEREAS,
Sublessee desires to sublease a portion of the Premises from Sublessor and Sublessor is willing to sublease the same, all on the terms and conditions hereinafter set forth; 

        NOW,
THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties covenant and agree as follows: 

        1.    Sublease of Subleased Premises.    For the rent and upon the terms and conditions herein, Sublessor hereby
subleases to Sublessee, and Sublessee hereby subleases from Sublessor approximately 10,000 square feet of rentable office space located on the first floor (the "Office Space") and approximately 11,550
square feet of rentable laboratory space located on the third floor (the "Lab Space") as shown on Exhibit B attached hereto (collectively, the
"Subleased Premises"). During the term hereof, Sublessee shall have access to the Subleased Premises and the parking lot adjacent to the Building twenty-four (24) hours a day,
7 days a week, excluding emergency events, which may cause the Building to limit access to tenants, subject to the terms of this Sublease. Sublessee shall have after hour access to the Building
by a card key system. Upon the date on which this Sublease has been fully executed by Sublessor and Sublessee and the Prime Lessor has delivered the "Consent" as hereinafter defined, Sublessee shall
have the right to enter the Subleased Premises for the purposes of commencing its "Improvement Work" as hereinafter defined, inspecting the Subleased Premises, taking measurements and preparing for
the move into the Subleased Premises, including installing system furniture and lab equipment. Sublessor shall have the right to have a representative present any time such early entry right is
exercised. If Sublessee enters the Subleased Premises prior to the Commencement Date (as hereunder defined), Sublessee shall be responsible for complying with all of the terms of this Sublease and the
Prime Lease to the extent incorporated herein by reference, other than the payment of Rent (as hereunder defined). 

        2.    Term.    The Term of this Sublease shall commence, at Sublessee's option, on May 1, 2005, provided that
Prime Lessor has delivered the "Consent" as hereinafter defined, or upon the later of (i) June 1, 2005; (ii) the date Sublessor delivers the Subleased Premises with Sublessor's
Work (as hereinafter defined) completed except for minor incomplete items or deficiencies, provided that any such incomplete items or deficiencies shall not hinder Sublessee's work in or about the
Subleased Premises, or prevent Sublessee from operating its business, and provided further that Sublessor shall complete such incomplete items or deficiencies within thirty (30) days following
the Commencement Date; (iii) the date on which this Sublease has been fully executed by Sublessor and Sublessee and the Prime Lessor has delivered the "Consent" as hereinafter defined;
(iv) delivery of a statement of 

1

 

decommissioning
from Sublessor to Sublessee from Sublessor's consultant confirming that the required close-out of radiation survey has been completed and the Subleased Premises qualify for
release under applicable decommissioning regulations; and (v) proof of a valid Sewer Use Discharge Permit in accordance with Paragraph 5(b) of this Sublease (the "Commencement Date"),
and shall expire at 11:59 p.m. on the day that is thirty-eight (38) months from the Commencement Date (the "Expiration Date") or such earlier date upon which said term may expire, be
canceled or be terminated pursuant to any of the terms or provisions of the Prime Lease, this Sublease or applicable law. If the Prime Lessor has not delivered the "Consent" as hereinafter defined, by
May 1, 2005, Sublessee shall have the right to terminate this Sublease by sending written notice to Sublessor. Sublessee shall have one option to renew this Sublease for one (1) year
(the "Extension Term") exercisable upon Sublessee providing Sublessor with written notice at least six (6) months prior to the expiration of the initial term of this Sublease, time being of the
essence. Notwithstanding the foregoing, if Sublessor desires to reoccupy the Subleased Premises for Sublessor's own occupancy Sublessor may, at its election, by notice to Sublessee given within
fifteen (15) days after receipt of Sublessee's notice of exercise of said renewal option, void such exercise and require that this Sublease nevertheless expire on the original Expiration Date
as set forth above. In the event of such election by and notice from Sublessor, this Sublease shall expire on the Expiration Date with the same effect as if Sublessee had no renewal option, except
that Sublessor shall in such event be prohibited from subleasing any portion of the Subleased Premises to any unrelated third party during the Extension Term. Sublessee shall begin paying Base Rent to
Sublessor on August 15, 2005 (the "Rent Commencement Date"). Notwithstanding the foregoing, Sublessee shall begin paying additional rent to Sublessor upon the Commencement Date. Year 1 of the
Sublease Term shall consist of twelve calendar months plus any partial month if the Commencement Date is other than the first day of a month. Year 2 of the Sublease Term shall commence upon the first
anniversary of the Commencement Date at which time the Base Rent for the First Floor Office Space shall increase to $19.00 per rentable square foot and the Base Rent for the Third Floor Lab Space
shall increase to $23.50 per rentable square foot. Year 3 of the Sublease Term shall commence upon the second anniversary of the Commencement Date at which time Base Rent for the First Floor Office
Space shall increase to $20.00 per rentable square foot and the Base Rent for the Third Floor Lab Space shall increase to $24.50 per rentable square foot. 

        3.    Appurtenant Rights.    Sublessee shall have, as appurtenant to the Subleased Premises, rights to use in common
with Sublessor and others entitled thereto Sublessor's rights in driveways, walkways, hallways, stairways and passenger elevators, freight elevators and loading docks convenient for access to the
Subleased Premises and the lavatories nearest thereto as shown on Exhibit B attached hereto. In addition, Sublessor grants Sublessee the right to
use, at no additional cost to Sublessee, in common with others, parking spaces on a non-exclusive basis in the automobile parking area throughout the term of this Sublease. The words
"automobile parking area" shall have the same meaning as set forth under Article XI of the Prime Lease. 

        4.    Base Rent.    Sublessee shall pay to Sublessor the following amounts as base rent (the "Base Rent") during the
term of this Sublease: 

	A.
	1ST FLOOR OFFICE SPACE

	Term
 
	 	Annual Amount
	 	Monthly Amount

annually to be billed on a monthly basis in the amount of $833.34 for electricity consumed in the Office Space. 

	B.
	3RD FLOOR LAB SPACE

	Term
 
	 	Annual Amount
	 	Monthly Amount
	 	P.R.S.F.

	Year 1	 	$	259,875.00	 	$	21,656.25	 	$	22.50
	Year 2	 	$	271,425.00	 	$	22,618.75	 	$	23.50

	Extension Term	 	$	294,525.00	 	$	24,543.75	 	$	25.50

        It
is intended by Sublessor and Sublessee that the Base Rent for the Lab Space be net of all costs and expenses related to the Lab Space. On account of the Lab Space only, Sublessee
shall during the Term
pay to Sublessor, as additional rent hereunder, (i) the Sublessee's Percentage (as hereinafter defined) of Common Expenses (as hereinafter defined), and (ii) one hundred percent (100%)
of Sublease Operating Costs (as hereinafter defined). The costs and expenses payable by Sublessee with respect to the Lab Space are collectively referred to herein as the
"Sublessee's Share." For purposes of this Sublease, the following terms shall have the following respective meanings: 

	(i)
	"Sublessee's Percentage" shall mean the rentable square footage of the Lab Space divided by the rentable square footage
of the Premises, expressed as a percentage. As of the Commencement Date, based upon the Lab Space as of such date containing 11,550 square feet and the Premises as of such date containing 85,430
rentable square feet, the Sublessee's Percentage shall be thirteen point fifty-two percent (13.52%).

	(ii)
	"Common Expenses" shall mean Landlord's Operating Expenses and Landlord's Taxes, both as defined in the Prime Lease.

	(iii)
	"Sublease Operating Costs" shall mean all charges, costs, expenses and obligations of every kind and nature whatsoever
that Sublessor may from time to time incur pursuant to the terms of the Prime Lease with respect to the Lab Space and Sublessee's Percentage of the costs detailed in  Exhibit D with regard
specifically to the Lab Space, or the operation or maintenance thereof, and not the general operation or maintenance of the
Premises or the Subleased Premises. 

        If
at any time Sublessor, in its reasonable judgment, determines that either Sublessor, Sublessee or any other subtenant in the Premises is consuming quantities of electricity in excess
of 110% (calculated on a per square foot basis) of the quantities being consumed by the other parties in those portions of the Premises occupied by such other party, then the party consuming such
excessive quantities of electricity shall be responsible for the cost of any such excess consumption. 

        Sublessor
may bill Sublessee for Sublessee's Share based on reasonably estimated projected costs (the "Estimated Costs"), in which case
Sublessee shall pay Sublessee's Share, as additional rent hereunder, based on such estimated amounts, such estimates to be based on the estimates Sublessee receives from Landlord. At least annually,
and not later than fifteen (15) days after Sublessor's receipt of Prime Lessor's annual accounting as more particularly described under Section 2.6.2 of the Prime Lease, Sublessor shall
provide to Sublessee copies of all records and documents relating to the annual accounting including, but not limited to, all materials and reconciliations supplied by the Prime Lessor together with
any independent allocation of any electricity charges by Sublessor pursuant to the preceding grammatical paragraph. If Sublessee disputes any of the charges that Prime Lessor charges to Sublessor
under the Prime Lease or that Sublessor charges Sublessee under this Sublease, Sublessee shall provide Sublessor with written notice of such dispute within twenty (20) days of receiving the
records and documents relating to the annual accounting. Upon receipt of Sublessee's notice of a dispute with respect to the annual accounting Sublessor may elect, at its sole option, to raise such 

3

 

dispute
with Prime Lessor or to allow Sublessee to raise such dispute directly with Prime Lessor; provided, however, if Prime Lessor will not allow Sublessee to contest the disputed charges, Sublessor
will contest the disputed charges on behalf of Sublessee. Sublessor shall review the Estimated Costs for the preceding year and compare such Estimated Costs against actual costs and expenses for such
preceding year. To the extent Sublessee's Share of the Estimated Costs exceeds Sublessee's Share of the actual costs and expenses, Sublessor shall credit (or promptly refund, as appropriate) such
excess amount against amounts due from Sublessee hereunder. To the extent Sublessee's Share of actual costs and expenses exceeds Sublessee's Share of Estimated Costs, Sublessee shall pay Sublessor the
amount of such deficiency upon demand as additional rent hereunder. 

        Base
Rent and additional rent shall sometimes be referred to as "Rent" herein. All Rent shall be due and payable in monthly installments in advance on the first day of each calendar
month, without demand, deduction, counterclaim or setoff, except as expressly provided for herein. Rent for any partial month shall be prorated and paid on the first day of such month. 

        5.    Permitted Uses.    Sublessee shall use the Subleased Premises only for general office uses including laboratory
use for research and development and the uses permitted under the Prime Lease. Sublessee shall not do, suffer or permit anything to be done in or upon the Subleased Premises or the Premises except in
accordance with and as permitted by the Prime Lease and applicable law. Sublessee shall comply with the certificate of occupancy relating to the Subleased Premises and with all laws, statutes,
ordinances, orders, rules, regulations and requirements of all federal, state and municipal governments and the appropriate agencies, officers, departments, boards and commissions thereof, and the
board of fire underwriters and/or the fire insurance rating organization or similar organization performing the same or similar functions, whether now or hereafter in force, applicable to the
Subleased Premises or to Sublessee's particular manner of use. Except as otherwise expressly provided herein, Sublessee shall apply in its own name for, and obtain at its sole expense, any and all
licenses, permits and other approvals that may be required from governmental authorities in connection with Sublessee's use of the Subleased Premises. 

        Subject
to the terms and conditions hereof, Sublessor has agreed to make available to Sublessee, in connection with Sublessee's use and occupancy of the Subleased Premises, certain
services, and to authorize Sublessee to use certain permits and licenses, held by Sublessor, including those services and licenses listed on  Exhibit D attached hereto, jointly with Sublessor
and others who may be authorized by Sublessor from time to time, as well as the following: 

	(a)
	Sublessor
shall provide customary janitorial and custodial services to the Subleased Premises in accordance with the schedule attached hereto as  Exhibit F.

	(b)
	Sublessor
grants Sublessee a license to the use, occupancy and operation of the Subleased Premises under the auspices of all existing municipal, state and federal licenses and permits
held by Sublessor with respect to the use and operation of laboratory and research facilities within the Subleased Premises including the Sewer Use Discharge Permit. Sublessee shall apply in its own
name for, and obtain at its sole expense its own Flammable Storage Permit for the materials and up to the maximum quantities set forth on  Exhibit E attached hereto. Sublessor will maintain
the Sewer Use Discharge Permit unless the Massachusetts Water Resource Authority requires
otherwise; in such event, Sublessor shall provide written notice thereof to Sublessee and Sublessee shall apply in its own name for, and obtain at its sole expense its own Sewer Use Discharge Permit.

	(c)
	Sublessor
grants Sublessee the right to connect to Sublessor's emergency generator through the outlets existing in the Subleased Premises as of the date hereof. 

        6.    Condition of Subleased Premises.    Sublessee represents that it has made or caused to be made a thorough
examination and inspection of the Subleased Premises and is familiar with the condition of 

4

 

every
part thereof. Sublessee agrees that, except as expressly provided herein, (i) it enters into this Sublease without relying upon any representations, warranties or promises by Sublessor,
its agents, representatives, employees, servants or any other person in respect of the Building or the Subleased Premises, (ii) no rights, easements or licenses are acquired by Sublessee by
implication or otherwise except as expressly set forth herein, (iii) Sublessor shall have no obligation to do any work in order to make the Subleased Premises suitable and ready for occupancy
and use by Sublessee other than ensuring that all building systems serving the Subleased Premises are in good working order, decommissioning the Lab Space in accordance with local and state
regulations, and performing any of the demising work if required by code to prepare the Subleased Premises for Sublessee's use and occupancy including "patch" and paint work, limited to repair and
painting of damaged wall areas, for the Office Space and replacing ceiling tiles where needed in the Lab Space (collectively "Sublessor's Work") which Sublessor shall perform at its expense, and
(iv) the Subleased Premises are in satisfactory condition. Sublessor shall deliver the Subleased Premises to Sublessee in broom clean condition and with all building systems serving the
Subleased Premises in good working order. If Sublessor has not completed Sublessor's Work by July 1, 2005, Sublessee shall have the right to terminate this Sublease by sending written notice to
Sublessor. 

        The
taking of possession by Sublessee of the Subleased Premises or any portion thereof delivered by Sublessor to Sublessee shall be conclusive evidence as against Sublessee, that, at the
time such possession was so taken, the Subleased Premises or such portion thereof were in good and satisfactory condition. 

        Following
the completion of the Improvement Work, Sublessee shall make no alterations, installations, removals, additions or improvements in or to the Subleased Premises or any other
portion of the Building except with the written consent of Sublessor (excluding cosmetic alterations in the Subleased Premises that do not affect the Building's structure or base building systems and
cost no more than $50,000.00 in the aggregate for a single project), which consent Sublessor shall grant or deny within fifteen (15) business days of such request and the written consent of
Prime Lessor in accordance with Section 5.9 of the Prime Lease. Notwithstanding the foregoing, Sublessor hereby approves Sublessee's improvement work (the "Improvement Work") as set forth on  Exhibit C attached hereto; provided, however, Sublessee acknowledges that it must still obtain Prime Lessor's consent to such Improvement Work in
accordance with Section 5.9 of the Prime Lease. Sublessee's contractor(s) shall perform the Improvement Work in compliance with the provisions of Section 5.9 of the Prime Lease. 

        Any
work shall be done in accordance with the plans and specifications submitted to and approved by Sublessor and Prime Lessor, except that Sublessor will not need to approve plans and
specifications for minor non-structural modifications that do not affect the Building's structure or base building systems, provided that Sublessee must still obtain Prime Lessor's
approval of the plans and specifications. No structural alterations shall be done. All such minor, non-structural modifications made by Sublessee shall be done at Sublessee's sole cost and
expense in a good and
workmanlike manner using new materials of first-class quality consistent with the style and finish of the Subleased Premises. Sublessee shall secure all necessary permits in advance of commencement of
any work and shall keep the Subleased Premises free of any mechanics or other liens and shall hold Sublessor and Prime Lessor harmless from any loss, cost or damage arising out of any work done by
Sublessee or its agents or contractors. Sublessee shall have the right to use its own contractor so long as said Contractor complies with the requirements of the Prime Lease. All contractors working
for Sublessee in the Subleased Premises shall be properly insured and shall provide certificates of insurance naming Sublessor and Prime Lessor as additional insureds prior to commencement of any
work. 

        Sublessee
shall keep and maintain the Subleased Premises and the fixtures and equipment therein clean and in good order, repair and condition, except for reasonable wear and tear and
damage by fire or other casualty or condemnation. Sublessee shall, at its sole cost and expense, decommission the Lab Space upon the Expiration Date or such earlier date upon which this Sublease may
expire, be canceled 

5

 

or
be terminated pursuant to any of the terms or provisions of the Prime Lease, this Sublease or applicable law. 

        7.    Insurance.    Sublessee shall maintain throughout the term of this Sublease such insurance in respect of the
Subleased Premises and the conduct and operation of business therein, with Sublessor and Prime Lessor listed as additional insureds as is required of "Tenant" pursuant to the terms of the Prime Lease
(including, without limitation, Section 5.5 as hereinafter incorporated by reference) with no penalty to Sublessor or Prime Lessor resulting from deductibles or self-insured
retentions effected in Sublessee's insurance coverage, and with such other endorsements and provisions as Sublessor or Prime Lessor may reasonably request. If Sublessee fails to procure or maintain
such insurance and to pay all premiums and charges therefor within ten (10) days after notice from Sublessor, Sublessor may (but shall not be obligated to) do so, whereupon Sublessee shall
reimburse Sublessor upon demand. All such insurance policies shall, to the extent obtainable, contain endorsements providing that (i) such policies may not be canceled except upon thirty
(30) days' prior notice to Sublessor and Prime Lessor, (ii) no act or omission of Sublessee shall affect or limit the obligations of the insurer with respect to any other named or
additional insured and (iii) Sublessee shall be solely responsible for the payment of all premiums under such policies and Sublessor, notwithstanding that it is or may be a named insured, shall
have no obligation for the payment thereof. Such insurance shall otherwise be reasonably acceptable to Sublessor in both form and substance. On or before the Commencement Date, Sublessee shall deliver
to Sublessor and Prime Lessor a certificate evidencing the foregoing coverages. Any endorsements to such certificates shall also be delivered to Sublessor and Prime Lessor upon issuance thereof.
Sublessee shall procure and pay for renewals of such insurance from time to time before the expiration thereof, and Sublessee shall deliver to Sublessor and Prime Lessor such renewal certificates at
least thirty (30) days before the expiration of any existing policy. In the event Sublessee fails so to deliver any such renewal certificate at least thirty (30) days before the
expiration of any existing policy, Sublessor shall have the right, but not the obligation, to obtain the same if Sublessee does not provide evidence of the same within ten (10) days of request
by Sublessor, where upon Sublessee shall reimburse Sublessor upon demand. 

        Sublessee
shall include in all such insurance policies any clauses or endorsements in favor of Prime Lessor including, but not limited to, waivers of the right of subrogation, which
Sublessor is required to provide pursuant to the provisions of the Prime Lease. Sublessor and Sublessee release and waive all claims against each other for loss or damage to Sublessor's and
Sublessee's personal property and their respective alterations, if any, in the Subleased Premises, except to the extent arising from any negligence or willful misconduct of Sublessor or Sublessee or
any of their respective employees, agents contractors or invitees. 

        8.    Indemnification.    Sublessee agrees to protect, defend (with counsel reasonably approved by Sublessor),
indemnify and hold Sublessor and Prime Lessor and their respective officers, agents and employees harmless from and against any and all liability, claims, suits, demands, judgments, costs, losses,
interest and expenses (except to the extent arising from any negligence or willful misconduct of Prime Lessor or Sublessor or their contractors, agents or employees), arising: (i) from the
conduct or management of or from any work or thing whatsoever done in the Subleased Premises during the term hereof; (ii) from any condition arising, and any injury to or death of persons,
damage to property or other event occurring or resulting from an occurrence in the Subleased Premises during the term hereof; and (iii) from any breach or default on the part of Sublessee in
the performance of any covenant or agreement on the part of Sublessee to be performed pursuant to the terms of this Sublease or from any willful misconduct or negligence on the part of Sublessee or
any of its agents, employees, licensees or assignees or any person claiming through or under Sublessee. Sublessee further agrees to indemnify Sublessor and Prime Lessor and their respective officers,
agents and employees from and against any and all liability, claims, suits, demands, judgments, costs, losses, interest and expenses (including, without being limited to, reasonable attorneys' fees
and expenses), incurred in connection 

6

 

with
any such indemnified claim or any action or proceeding brought in connection therewith. The provisions of this Paragraph are intended to supplement any other indemnification provisions contained
in this Sublease and in the Prime Lease to the extent incorporated by reference herein. Any non-liability, indemnity or hold harmless provisions in the Prime Lease for the benefit of Prime
Lessor that are incorporated herein by reference shall be deemed to inure to the benefit of Sublessor and Prime Lessor. 

        Sublessor
agrees to protect, defend (with counsel reasonably approved by Sublessee), indemnify and hold Sublessee and its officers, agents and employees harmless from and against any and
all claims, costs, expenses, losses and liabilities (except to the extent arising from the negligence or willful misconduct of Sublessee or its contractors, agents or employees) arising:
(i) from any injury to or death of persons or damage to property occurring or resulting from an occurrence in the Premises or the Building caused by the negligence or willful misconduct of
Sublessor, its contractors, agents, employees, licensees or assignees or any person claiming through or under Sublessor during the term hereof and (ii) from any breach or default on the part of
Sublessor in the performance of any covenant or agreement on the part of Sublessor to be performed pursuant to the terms of this Sublease. 

        9.    No Assignment or Subletting.    Sublessee shall not assign, sell, mortgage, pledge or in any manner transfer
this Sublease or any interest herein, or the term or estate granted hereby or the rentals hereunder, or sublet the Subleased Premises or any part thereof, or grant any concession or license or
otherwise permit occupancy of all or any part of the Subleased Premises by any person, without the prior written consent of Prime Lessor and Sublessor, which consent of Sublessor shall not be
unreasonably withheld, conditioned or delayed. If Sublessor does not either grant or withhold its consent to a proposed assignment, subletting, concession or license within thirty (30) days of
receipt of Sublessee's request for such consent, Sublessor's consent shall be deemed approved; provided, however, Sublessee must still obtain Prime Lessor's consent to such proposed assignment,
subletting, concession or license. Neither the consent of Sublessor or Prime Lessor to an assignment, subletting, concession, or license, nor the references in this Sublease to assignees, subtenants,
concessionaires or licensees, shall in any way be construed to relieve Sublessee of the requirement of obtaining the consent of Sublessor and Prime Lessor to any further assignment or subletting or to
the making of any assignment, subletting, concession or license for all or any part of the Subleased Premises. Notwithstanding any assignment or subletting, including, without limitation, any
assignment or subletting permitted or consented to, the original Sublessee named herein and any other person(s) who at any time was or were Sublessee shall remain fully liable under this Sublease. If
this Sublease is assigned, or if the Subleased Premises or any part thereof is underlet or occupied by any person or entity other than Sublessee, Sublessor may, after default by Sublessee, following
notice and the expiration of any cure period, collect rent from the assignee, undertenant or occupant, and apply the net amount collected to the rents payable by Sublessee hereunder, but no
assignment, underletting, occupancy or collection shall be deemed a waiver of the provisions hereof, the acceptance of the assignee, undertenant or occupant as tenant, or a release of Sublessee from
the further performance by Sublessee of the covenants hereunder to be performed on the part of Sublessee. Any attempted assignment or subletting without the prior written consent of the Sublessor and
the Prime Lessor shall be void. Notwithstanding the provisions of this Paragraph 9, this Sublease may be assigned, or the Subleased Premises may be sublet, in whole or in part, after prior
notice to Sublessor but without the consent of Sublessor and without any termination right of Sublessor being applicable thereto, (i) to any corporation or other entity into which or with which
Sublessee may be merged or consolidated or to any corporation or entity to which all or substantially all of the Sublessee's assets or capital stock will be transferred, or (ii) to any
corporation which is an affiliate, subsidiary, parent or successor of Sublessee, provided in all cases the surviving corporation or entity shall provide reasonable evidence that it has
creditworthiness at least equal to the greater of (i) the net worth of Sublessee as of the date of such corporate transaction, and (ii) as of the date of this Sublease, and shall agree
in writing with Sublessor to be 

7

 

bound
by all of the terms and conditions of this Sublease (all of the foregoing being referred to as a "Permitted Transfer"). 

        10.    Primacy and Incorporation of Prime Lease.    

        (a)   This
Sublease is and shall be subject and subordinate to the Prime Lease and to all matters to which the Prime Lease is or shall be subject and subordinate, and to all
amendments, modifications, renewals and extensions of or to the Prime Lease and Sublessor purports hereby to convey, and Sublessee takes hereby, no greater rights then those accorded to or taken by
Sublessor as "Tenant" under the terms of the Prime Lease. To the extent incorporated herein, Sublessee covenants and agrees that it will perform and observe all of the provisions contained in the
Prime Lease to be performed and observed by the "Tenant" thereunder as applicable to the Premises, other than the payment of rent. Notwithstanding the foregoing, Sublessee shall have no obligation to
(i) cure any default of Sublessor under the Prime Lease unless caused by Sublessee's default under this Sublease, (ii) perform any obligation of Sublessor under the Prime Lease which
arose prior to the Commencement Date and Sublessor failed to perform, (iii) repair any damage to the Premises caused by Sublessor, (iv) remove any alterations or additions installed
within the Premises prior to the Commencement Date, (v) indemnify Sublessor or Prime Lessor with respect to any negligence or willful misconduct of Sublessor, its agents, employees or
contractors, or (vi) discharge any liens on the Premises or the Building which arise out of any work performed, or claimed to be performed, by or at the direction of Sublessor. Except to the
extent inconsistent with the context hereof, capitalized terms used and not otherwise defined herein shall have the meanings ascribed to them in the Prime Lease. Further, except as set forth below,
the terms, covenants and conditions of the Prime Lease are incorporated herein by reference as if such terms, covenants and conditions were stated herein to be the terms, covenants and conditions of
this Sublease, so that except to the extent that they are inconsistent with or modified by the provisions of this Sublease, for the purpose of incorporation by reference each and every referenced
term, covenant and condition of the Prime Lease binding upon or inuring to the benefit of the "Landlord" thereunder shall, in respect of this Sublease and the Subleased Premises, be binding upon or
inure to the benefit of Sublessor, and each and every referenced term, covenant and condition of the Prime Lease binding upon or inuring to the benefit of the "Tenant" thereunder shall, in respect of
this Sublease, be binding upon or inure to the benefit of Sublessee, with the same force and effect as if such terms, covenants and conditions were completely set forth in this Sublease.
Notwithstanding the foregoing, for purposes of this Sublease, as to such incorporated terms, covenants and conditions:

in the Prime Lease to the "Premises", "Premises A" and "Premises B" shall be deemed to refer to the "Subleased Premises" hereunder;

	(ii)
	references
in the Prime Lease to "Landlord" and to "Tenant" shall be deemed to refer to "Sublessor" and "Sublessee" hereunder, respectively, except that where the terms
"Landlord" is used in the context of ownership or management of the entire Building, such term shall be deemed to mean "Prime Lessor";

	(iii)
	references
in the Prime Lease to "this Lease" shall be deemed to refer to "this Sublease" (except when such reference in the Prime Lease is, by its terms (unless
modified by this Sublease), a reference to any other section of the Prime Lease, in which event such reference shall be deemed to refer to the particular section of the Prime Lease);

	(iv)
	references
in the Prime Lease to the "Term Commencement Date" shall be deemed to refer to the "Commencement Date" hereunder;

	(v)
	references
in the Prime Lease to the "Rent Commencement Date" shall be deemed to refer to the "Rent Commencement Date" hereunder; 

8

  

	(vi)
	references
in the Prime Lease to the "Annual Fixed Rent", "Additional Rent" and "rent" shall be deemed to refer to the "Base Rent", "additional rent" and "Rent",
respectively, as defined hereunder

	(vii)

        Notwithstanding
the foregoing, the following provisions of the Prime Lease, Exhibits and Schedules annexed thereto are not incorporated herein by reference and shall not, except as to
definitions set forth therein, have any applicability to this Sublease: Articles/Sections: 1.1 (except, however, the definitions of "Land", "Permitted Uses" and "Public Liability Insurance" are
incorporated herein), 1.2, 2.1, 2.4, 2.5, 2.6.1, 2.6.2, 2.7, III, 4.1.4, the third grammatical paragraph of 4.2, 4.3.3, 4.4, 5.8, 6.1, 6.2, 8.2, 8.5, 8.6, 8.14, 8.17, 8.18, 8.20, 9.1, the last
grammatical paragraph of 9.2 and X; and Exhibits A, B, E, F, H, I and J. 

        Where
reference is made in the following Sections to "Landlord", the same shall be deemed to refer only to "Prime Lessor": Articles/Sections: 2.2, 2.3, 2.6.3, 2.6.4, IV, 5.3 and XI. 

        Where
reference is made in the following Sections to "Landlord", the same shall be deemed to refer to "Prime Lessor" and "Sublessor": Articles/Sections: 5.7 and 5.10. 

        (b)   Notwithstanding
such incorporation by reference, Sublessee acknowledges that pursuant to the Prime Lease, certain services, repairs, restorations, equipment and access
to and for the Premises and insurance coverage of the Building are in fact to be provided by Prime Lessor and Sublessor shall have no obligation during the Term of this Sublease to provide any such
services, repairs, restorations, equipment, access or insurance coverage. Sublessee agrees to look solely to Prime Lessor for the furnishing of such services, repairs, restorations, equipment, access
and insurance coverage. Sublessor shall cooperate reasonably with Sublessee in obtaining for Sublessee's benefit the performance by Prime Lessor of its obligations under the Prime Lease, but Sublessor
shall in no event be liable to Sublessee, nor, except as otherwise expressly set forth in the casualty or condemnation provisions of the Prime Lease, shall the obligations of Sublessee hereunder be
impaired or the performance thereof excused because of any failure or delay on Prime Lessor's part in furnishing such services, repairs, restorations, equipment, access or insurance coverage. If Prime
Lessor fails to provide to the any of the services described in the Prime Lease, and such failure or any other cause or circumstance (other than Sublessee's act or default) materially adversely
interferes with Sublessee's use and enjoyment of the Subleased Premises, then Sublessee shall be entitled to an adjustment of Rent to the extent that Sublessor receives an adjustment of rent under the
Prime Lease. 

        (c)   Notwithstanding
anything to the contrary contained in the Prime Lease, the time limits (the "Notice Periods") contained in the Prime Lease for the giving of notices,
making of demands or performing of any act, condition or covenant on the part of the "Tenant" (including any grace periods set forth in Article VII of the Prime Lease), thereunder, or for the
exercise by the "Tenant", thereunder of any right, remedy or option, are changed for the purposes of incorporation herein by reference by shortening the same in each instance by five (5) days
(or by three (3) days if the notice period is ten (10) days or less), so that in each instance Sublessee shall have five (5) (or three (3), as applicable) fewer days to observe or
perform hereunder than Sublessor has as the "Tenant" under the Prime Lease; provided, however, that if
the Prime Lease allows a Notice Period of five (5) days or less, then Sublessee shall nevertheless be allowed the number of days equal to one-half of the number of days in each
Notice Period to give any such notices, make any such demands, perform any such acts, conditions or covenants or exercise any such rights, remedies or options; provided, further, that if
one-half of the number of days in the Notice Period is not a whole number, Sublessee shall be allowed the number of days equal to one-half of the number of days in the Notice
Period rounded up to the next whole number. 

9

 

        (d)   Notwithstanding
anything to the contrary contained in this Sublease (including, without limitation, the provisions of the Prime Lease incorporated herein by reference),
Sublessor makes no representations or warranties whatsoever with respect to the Subleased Premises, this Sublease, the Prime Lease or any other matter, either express or implied, except as expressly
set forth herein, and except that Sublessor represents and warrants, as of the date of execution hereof, (i) that it is the holder of the interest of the "Tenant" under the Prime Lease and said
interest is not the subject of any lien, assignment, conflicting sublease, or other hypothecation or pledge; (ii) that the Prime Lease is in full force and effect, unmodified and constitutes
the entire agreement between the Prime Lessor and Sublessor in respect of the Subleased Premises; (iii) that no notices of default have been served on Sublessor under the Prime Lease which have
not been cured; (iv) that Sublessor shall send Sublessee copies of any notices of default that may be served on Sublessor under the Prime Lease within three (3) business days of
receiving the same; (v) that Sublessor shall not voluntarily surrender the Subleased Premises or terminate the Prime Lease during the Term of the Sublease, except as provided in
Paragraph 21 hereof; and (vi) to the best of Sublessor's knowledge, neither Sublessor nor Prime Lessor is in default under the Prime Lease. 

        11.    Certain Services and Rights.    Except to the extent otherwise expressly provided herein, the only services or
rights to which the Sublessee is entitled hereunder, including without limitation rights relating to the repair, maintenance and restoration of the Subleased Premises, are those services and rights to
which Sublessor is entitled under the Prime Lease. Sublessee acknowledges and agrees that Sublessor shall have no obligation to furnish any services whatsoever to Sublessee, any such obligation being
that of the Prime Lessor under the Prime Lease, and that, as set forth in Paragraph 11(b) hereof, the sole obligation of Sublessor hereunder with respect to such services is to cooperate
reasonably with Sublessee to obtain Prime Lessor's performance. 

        12.    Compliance with Prime Lease.    Sublessee shall neither do nor permit anything to be done which would cause the
Prime Lease to be terminated or forfeited by reason of any right of termination or forfeiture reserved or vested in Prime Lessor under the Prime Lease, and Sublessee shall defend, indemnify and hold
Sublessor harmless from and against any and all liability, claims, suits, demands, judgments, costs, losses, interest and expenses (including, without being limited to, reasonable attorneys' fees and
expenses) of any kind whatsoever by reason of any breach or default on the part of Sublessee by reason of which the Prime Lease may be terminated or forfeited. Sublessee covenants and agrees that
Sublessee will not do anything which would constitute a default under the provisions of the Prime Lease or omit to do anything which Sublessee is obligated to do under the terms of this Sublease, that
would constitute a default under the Prime Lease. Sublessor covenants and agrees that Sublessor will not do anything which would constitute a default (beyond any applicable grace or cure period under
the Prime Lease) under the provisions of the Prime Lease or omit to do anything which Sublessor is obligated to do under the terms of this Sublease (beyond any applicable grace or cure period), which
omission would constitute a default under the Prime Lease nor shall Sublessor voluntarily surrender or terminate the Prime Lease (except pursuant to the express provisions thereof or
Paragraph 21 hereof), nor shall Sublessor agree to modify or amend the Prime Lease in any way that will reduce the rights or increase the obligations of Sublessee under this Sublease. 

        13.    Default.    In the event that Sublessee shall default in any of its obligations hereunder beyond applicable
cure periods, including any default of the nature described in the Prime Lease beyond applicable cure periods, Sublessor shall have available to it all of the rights and remedies available to Prime
Lessor under the Prime Lease, including without limitation Article VII thereof as and to the extent incorporated herein by reference, as though Sublessor were the "Landlord" thereunder and
Sublessee the "Tenant" thereunder. Sublessee further agrees to reimburse Sublessor for all actual and out-of-pocket costs and expenses, including reasonable attorneys' fees,
incurred by Sublessor in asserting or enforcing its rights hereunder against Sublessee or any other party. 

10

 

        14.    Brokerage.    Sublessee and Sublessor represent that they have not dealt with any broker in connection with
this Sublease other than CB Richard Ellis/Whittier Partners and Richards Barry Joyce & Partners (the "Brokers"). Each party agrees to indemnify and hold harmless the other from and against any
and liability, claims, suits, demands, judgments, costs, losses, interest and expenses (including, without being limited to, reasonable attorneys' fees and expenses) which the indemnified party may be
subject to or suffer by reason of any claim made by any person, firm or corporation other than the Brokers for any commission, expense or other compensation as a result of the execution and delivery
of this Sublease, which is based on alleged conversations or negotiations by said person, firm or corporation with the indemnifying party. Sublessor shall pay the Brokers the brokerage commission, or
other compensation due the Brokers in connection with this Sublease under separate agreements between and among Sublessor and Brokers and shall indemnify and hold Sublessee harmless from and against
any and all liability, claims, suits, demands, judgments, costs, losses, interest and expenses (including, without being limited to, reasonable attorneys' fees and expenses) which Sublessee may be
subject to or suffer by reason of any claim made by the Brokers for any commission, fee or other compensation as a result of the execution and delivery of this Sublease, other than a claim based upon
any agreement with Sublessee or Sublessee's agents, representatives or employees. 

        15.    Security Deposit.    On the date of execution of this Sublease by Sublessee, Sublessee at its sole cost and
expense shall deliver to Sublessor, in a form and from a financial institution acceptable to Sublessor, an irrevocable, unconditional standby letter of credit in the amount of $36,667.00 (the "Letter
of Credit"), as security for the full and faithful performance and observance by Sublessee of Sublessee's covenants and obligations under this Sublease (the "Security Deposit"). Sublessee shall be
solely responsible for all costs and expenses of obtaining, amending, renewing, replacing and/or transferring such Letter of Credit. The Letter of Credit shall have an expiration date not earlier than
thirty (30) days following the expiration of the Term of this Sublease. Upon the occurrence of an Event of Default, including, but not limited to, the non-payment of Rent specified
in Paragraph 4 hereof, Sublessor may, without giving notice to Sublessee, draw upon the Letter of Credit to the extent required for the payment of any Rent or any other sums as to which
Sublessee is in default or for any sum which Sublessor may expend or may be required to expend by reason of Sublessee's default in respect of any of the terms, covenants and conditions of this
Sublease, including, but not limited to, any damages or deficiency in the reletting of all or any portion of the Premises, whether such damages or deficiency accrue before or after summary proceedings
or other re-entry by Sublessor. If Sublessor draws upon the Letter of Credit to cure any default, Sublessee shall cause the Letter of Credit to be restored to its original amount and
failure to do so within ten (10) days after receiving written notice from Sublessor shall be deemed an Event of Default hereunder. Sublessee understands that its
potential liability under this Sublease is not limited to the amount of the Security Deposit. Use of said Security Deposit by Sublessor shall not constitute a waiver, but is in addition to other
remedies to Sublessor under this Sublease and under law. In the event of any transfer of Sublessor's interest in the Premises, Sublessor shall either return the Security Deposit to Sublessee or assign
its interest in the Security Deposit to the transferee or assignee and Sublessor shall thereupon be released by Sublessee from all liability for the return or payment thereof; and Sublessee shall look
solely to the new sublessor for the return or payment of the same; and the provisions hereof shall apply to every transfer or assignment made of the same to a new sublessor. Sublessee shall not assign
or encumber or attempt to assign or encumber the Security Deposit and neither Sublessor nor its successors or assigns shall be bound by any such assignment, encumbrance, attempted assignment or
attempted encumbrance. 

        16.    Notices.    All notices, consents, approvals, demands, bills, statements and requests which are required or
desired to be given by either party to the other hereunder shall be in writing and shall be governed by Section 8.3 of the Prime Lease as incorporated herein by reference, except that the
mailing addresses for Sublessor and Sublessee shall initially be those first set forth above, and after the Commencement Date, to Sublessee at the Subleased Premises, with a copy to William T. Whelan,
Esquire, Mintz, Levin, Cohn, Ferris, Glovsky & Popeo, P.C., One Financial Center, Boston, 

11

 

Massachusetts
02111. Communications and payments to the Prime Lessor shall be given in accordance with, and subject to, Section 8.3 of the Prime Lease. 

        17.    Interpretation.    This Sublease shall be construed without regard to any presumption or other rule requiring
construction against the party causing this Sublease to be drafted. Each covenant, agreement, obligation or other provision of this Sublease shall be deemed and construed as a separate and independent
covenant of the party bound by, undertaking or making the same, which covenant, agreement, obligation or other provision shall be construed and interpreted in the context of the Sublease as a whole.
All terms and words used in this Sublease, regardless of the number or gender in which they are used, shall be deemed to include any other number and any other gender as the context may require. The
word "person" as used in this Sublease shall mean a natural person or persons, a partnership, a corporation or any other form of business or legal association or entity. Terms used herein and not
defined shall have the meaning set forth in the Prime Lease. 

        18.    Fire or Casualty; Eminent Domain.    In the event the Subleased Premises (or access thereto or systems serving
the same) are subjected to a fire or other casualty or to a taking by eminent domain that interferes with the use and enjoyment by Sublessee of a material portion of the Subleased Premises, Sublessee
shall be entitled to an equitable adjustment of Rent until tenantable occupancy is restored. At any time that such interference has not been remedied and tenantable occupancy restored after ninety
(90) days from the date such interference was first experienced, Sublessee may, by notice to Sublessor, terminate this Sublease. In the event of any taking of the Subleased Premises, Sublessee
assigns to Prime Lessor any right Sublessee may have to any damages or award, except that Sublessee shall be entitled to any award made on account of Sublessee's personal property or for Sublessee's
moving expenses. Sublessee shall not make claims against Sublessor, Prime Lessor or the condemning authority for damages. 

        19.    Signage.    Subject to the consent of Prime Lessor as required under the Prime Lease, if any, Sublessee has the
right, at its sole cost and expense, to install signage (i) consistent with Sublessor's signage and that of any other subtenants on the Building lobby directory and on the first and third floor
entrances to the Subleased Premises and (ii) on a portion of Sublessor's space on the monument sign equal in size to its pro rata share of the Premises. 

        20.    Right to Cure Sublessee's Defaults.    (a) If Sublessee shall at any time fail to make any payment or
perform any other obligation of Sublessee hereunder after any applicable notice and cure periods, then Sublessor shall have the right, but not the obligation, after notice to Sublessee, or without
notice to Sublessee in the case of any emergency, and without waiving or releasing Sublessee from any obligations of Sublessee hereunder, to make such payment or perform such other obligation of
Sublessee in such manner and to such extent as Sublessor shall deem necessary, and in exercising any such right, to pay any incidental costs and expenses, employ attorneys, and incur and pay
reasonable attorneys' fees. Sublessee shall pay to Sublessor upon demand as additional rent all sums so paid by Sublessor and all incidental costs and expenses of Sublessor in connection therewith,
together with interest thereon at an annual rate equal to the rate four percent (4%) above the base rate or prime rate then reported in the Wall Street
Journal, or the maximum rate permitted by law. Such interest shall be payable with respect to the period commencing on the date such expenditures are made by Sublessor and
ending on the date such amounts are repaid by Sublessee. The provisions of this Paragraph shall survive the Expiration Date or the sooner termination of this Sublease. 

        (b)   If
(i) Sublessor fails to perform any of its obligations under the Prime Lease (other than by reason of Sublessee's acts or omissions or events of a nature beyond
Sublessor's reasonable control) and the Prime Lessor has given a notice of default with respect thereto, which failure has not been cured within the applicable grace and cure periods under the Prime
Lease; (ii) Sublessee is not in default under this Sublease beyond any applicable notice and/or cure period; (iii) such default by Sublessor does not arise out of the acts or omissions
of Sublessee, its agents, contractors, employees, 

12

 

sublessees
or licensees; (iv) Sublessee notifies Sublessor after the expiration of the applicable grace and cure periods under the Prime Lease of such failure and of Sublessee's intention to
cure same, which notice shall specify that such notice is being given in accordance with this Paragraph 20(b); and (v) such failure continues for not less than ten (10) business
days from the date Sublessor receives such notice from Sublessee, then at Sublessee's election (if Sublessee elects to exercise its cure rights hereunder), Sublessee may take such actions as may be
reasonably necessary to cure such failure and Sublessor shall reimburse Sublessee for the reasonable out-of-pocket costs incurred by Sublessee in performing same within thirty
(30) days after receipt by Sublessor of a written statement from Sublessee as to the amount of such costs. 

        21.    Termination of Prior Leases.    If for any reason the term of the Prime Lease shall terminate prior to the
Expiration Date, this Sublease shall thereupon automatically terminate as to the premises demised under the Prime Lease and Sublessor shall not be liable to Sublessee by reason thereof;  provided,
however, that Sublessor agrees that so long as Sublessee is not in default hereunder,
Sublessor shall not voluntarily surrender or terminate the Prime Lease, except in accordance with rights expressly reserved
to Sublessor under Article VI of the Prime Lease in the event of a taking or casualty. Notwithstanding the foregoing, if the Prime Lease gives Sublessor any right to terminate the Prime Lease
in the event of the partial or total damage, destruction, or condemnation of the Subleased Premises or the Building, the exercise of such right by Sublessor shall not constitute a default or breach
hereunder. 

        Upon
the expiration or termination of this Sublease, whether by forfeiture, lapse of time or otherwise, or upon the termination of Sublessee's right of possession, Sublessee shall
(i) remove and restore any and all signage it may have installed and such alterations, installations, additions and improvements as Sublessor may have specified at the time Sublessor consented
to the same and (ii) at once surrender and deliver the Subleased Premises in the condition and repair required by, and in accordance with the provisions of, this Sublease and the Prime Lease,
including without limitation Section 5.10 of the Prime Lease as incorporated herein by reference. If Sublessee shall fail to remove any of Sublessee's property from the Subleased Premises, such
property shall be deemed abandoned, and Sublessor is hereby authorized, without liability to Sublessee for loss or damage thereto, at the sole risk of Sublessee, to (a) remove and store such
property at Sublessee's expense; (b) retain such property, in which case all right, title and interest therein shall accrue to Sublessor; or, (c) sell such property and retain the
proceeds from such sale, or otherwise dispose or destroy such property. 

        22.    Consents and Approvals.    All references in this Sublease to the consent or approval of Prime Lessor and/or
Sublessor shall be deemed to mean the written consent or approval of Prime Lessor and/or Sublessor, as the case may be, and no such consent or approval of Prime Lessor and/or Sublessor, as the case
may be, shall be effective for any purpose unless such consent or approval is set forth in a written instrument executed by Prime Lessor and/or Sublessor, as the case may be. In all provisions
requiring the approval or consent of Sublessor (whether pursuant to the express terms of this Sublease or the terms of the Prime Lease incorporated herein), Sublessee shall be required to obtain the
approval or consent of Prime Lessor and then to obtain like approval or consent of Sublessor. If Sublessor is required or has determined to give its consent or approval to a matter as to which consent
or approval has been requested by Sublessee, Sublessor shall cooperate reasonably with Sublessee in endeavoring to obtain any required Prime Lessor's consent or approval upon and subject to the
following terms and conditions: (i) Sublessee shall reimburse Sublessor for any reasonable out-of-pocket costs incurred by Sublessor in connection with seeking such
consent or approval, except with respect to the "Consent" (as hereinafter defined) to this Sublease and any amendments to this Sublease (ii) Sublessor shall not be required to make any payments
to Prime Lessor or to enter into any agreements or to modify the Prime Lease, or this Sublease in order to obtain any such consent or approval, (iii) if Sublessee agrees or is otherwise
obligated to make any payments to Sublessor, or Prime Lessor in connection with such request for such consent or approval, Sublessee shall have made 

13

 

arrangements
satisfactory to Sublessor for such payments and (iv) Sublessee shall indemnify and hold Sublessor harmless from and against all liability, claims, suits, demands, judgments, costs,
losses, interest and expenses (including, without being limited to, reasonable attorneys' fees and expenses) Sublessor shall suffer or incur in connection with seeking such consent or approval.
Nothing contained in this Article shall be deemed to require Sublessor to give any consent or approval simply because Prime Lessor has given such consent or approval and, unless provision to the
contrary is expressly made herein, Sublessor's consent may be withheld at its sole election. Notwithstanding anything to the contrary contained in this Sublease, Sublessee shall not be required to
reimburse Sublessor or Prime Lessor for any costs incurred by either of them in connection with seeking the Consent as hereinafter defined. Except as expressly provided for herein, all references in
this Sublease to the consent or approval of Sublessor shall be deemed to mean consent not to be unreasonably withheld, delayed or conditioned. 

        23.    No Privity of Estate.    Nothing contained in this Sublease shall be construed to create privity of estate or
of contract between Sublessee and Prime Lessor and Prime Lessor is not obligated to recognize or to provide for the non-disturbance of the rights of Sublessee hereunder. 

        24.    Successors and Assigns.    The provisions of this Sublease, except as herein otherwise specifically provided,
shall extend to bind and inure to the benefit of the parties hereto and their respective personal representatives, heirs, successors and permitted assigns. 

        25.    Waiver of Jury Trial and Right to Counterclaim.    The parties hereto hereby waive any rights which they may
have to trial by jury in any summary action or other action, proceeding or counterclaim arising out of or in any way connected with this Sublease, the relationship of Sublessor and Sublessee, the
Subleased Premises and the use and occupancy thereof, and any claim for injury or damages. Sublessee also hereby waives all right to assert or interpose a counterclaim in any summary proceeding or
other action or proceeding to recover or obtain possession of the Subleased Premises. The parties hereto hereby waive any rights which they may have to trial by jury in any summary action or other
action, proceeding or counterclaim arising out of or in any way connected with this Sublease, the relationship of Sublessor and Sublessee, the Subleased Premises and the use and occupancy thereof, and
any claim for injury or damages. Sublessee also hereby waives all right to assert or interpose a counterclaim (other than mandatory or compulsory counterclaims) in any summary proceeding or other
action or proceeding to recover or obtain possession of the Subleased Premises. 

        26.    Estoppel Certificates.    Sublessee shall, within ten (10) business days after each and every request by
Sublessor, execute, acknowledge and deliver to Sublessor or any party reasonably designated by Sublessor, without cost or expense to Sublessor, a statement in writing (a) certifying that this
Sublease is unmodified and, to the best knowledge of Sublessee, is in full force and effect (or if there have been modifications, that the same is in full force and effect as modified, and stating
such modifications); (b) specifying the dates to which Base Rent, additional and electricity charges have been paid; (c) stating whether or not, to the best knowledge of Sublessee,
Sublessor is in default in the performance or observance of its obligations under this Sublease and, if so, specifying each such default; (d) stating whether or not, to the best knowledge of
Sublessee, any event has occurred which, with the giving of notice or passage of time, or both, would constitute a default by Sublessor under this Sublease, and, if so, specifying each such default;
(e) stating whether or not, to the best knowledge of Sublessee, any event has occurred which, with the giving of notice or passage of time, or both, would constitute a default by Prime Lessor
under the Prime Lease with respect to the Subleased Premises, and, if so, specifying such event; (f) describing all notices of default submitted by Sublessee to Sublessor and Prime Lessor with
respect to this Sublease, or the Prime Lease from and after the date hereof; and (g) containing such other information with respect to the Subleased Premises or this Sublease as Sublessor shall
reasonably request. Sublessee hereby acknowledges and agrees that any such statement delivered pursuant to this Paragraph may be relied upon by any prospective assignee, transferee or mortgagee of the
leasehold estate of Sublessor under the Prime Lease. 

14

 

        Sublessor
shall, within ten (10) business days after each and every request by Sublessee, execute, acknowledge and deliver to Sublessee or any party reasonably designated by
Sublessee, without cost or expense to Sublessee, a statement in writing (a) certifying that this Sublease is unmodified and, to the best knowledge of Sublessor, is in full force and effect (or
if there have been modifications, that the same is in full force and effect as modified, and stating such modifications); (b) specifying the dates to which Base Rent, additional and electricity
charges have been paid; (c) stating whether or not, to the best knowledge of Sublessor, Sublessee is in default in the performance or observance of its obligations under this Sublease and, if
so, specifying each such default; (d) stating whether or not, to the best knowledge of Sublessor, any event has occurred which, with the giving of notice or passage of time, or both, would
constitute a default by Sublessee under this Sublease, and, if so, specifying each such default; (e) stating whether or not, to the best knowledge of Sublessor, any event has occurred which,
with the giving of notice or passage of time, or both, would constitute a default by Prime Lessor under the Prime Lease with respect to the Subleased Premises, and, if so, specifying such event;
(f) describing all notices of default submitted by Sublessor to Sublessee and Prime Lessor with respect to this Sublease, or the Prime Lease from and after the date hereof; and
(g) containing such other information
with respect to the Subleased Premises or this Sublease as Sublessee shall reasonably request. Sublessor hereby acknowledges and agrees that any such statement delivered pursuant to this Paragraph may
be relied upon by any prospective assignee, transferee or mortgagee of the leasehold estate of Sublessee under the Sublease. 

        27.    Consent of Prime Lessor.    This Sublease is subject to the approval and consent of Prime Lessor, which
Sublessor agrees to use all reasonable efforts to obtain. This Sublease shall not become effective unless and until a written approval and consent (the "Consent") is executed and delivered by the
Prime Lessor, which Consent shall consent to this Sublease. After the Sublessor receives the Consent from the Prime Lessor, Sublessor agrees to promptly deliver a fully-executed original of the
Consent to Sublessee. The effectiveness of this Sublease is subject to and conditional upon the receipt by Sublessor and Sublessee of the Consent. To the extent that Sublessor has not already done so,
upon execution of this Sublease by Sublessee, Sublessor will promptly apply to the Prime Lessor for the Consent and Sublessor will promptly inform Sublessee as to receipt of the Consent (if and when
it is received) and deliver to Sublessee a copy of the same. If a fully executed original of the Consent is not delivered to the Sublessee by May 1, 2005, Sublessee shall have the right to
terminate this Sublease by promptly sending notice of termination to Sublessor. 

        28.    Limitation of Liability.    No director, officer, shareholder, employee, adviser or agent of Sublessor shall be
personally liable in any manner or to any extent under or in connection with this Sublease. In no event shall Sublessor or Sublessee or any of their respective directors, officers, shareholders,
employees, advisers or agents be responsible for any consequential, indirect, punitive or special damages or interruption or loss of business, income or profits, or claims for constructive eviction,
nor shall Sublessor or Sublessee be liable for loss of or damage to artwork, securities or other valuables, or for other property not in the nature of ordinary fixtures, furnishings and equipment used

        29.    (Intentionally omitted)    

        30.    Option to Expand.    Sublessee shall have the right of first negotiation to sublease any additional space on
the third floor of the Building (the "Expansion Space") that "becomes available" during the Term of this Sublease upon and subject to the terms of this Sublease. Space shall be deemed to "become
available" when Sublessor ceases to occupy the same or the sublease for the then current occupant of the space expires or is otherwise terminated and in either case Sublessor determines to offer some
or all thereof on the open market for sublease. Space shall not be deemed to "become available" if the space is: (i) released to the then current tenant of the space by renewal, extension or
renegotiation, (ii) subject to a specific expansion right of another subtenant in the Building existing as of the Commencement Date or subsequently entered into in compliance with this
Paragraph 30, or 

15

 

(iii) not
leased to a subtenant as of the date of this Sublease (until that space is leased, and then subsequently becomes available). Sublessor agrees that it will not offer any space on the
third floor of the Building that has "become available" without first complying with the terms of this Paragraph 30 unless and until this Sublease has terminated or expired in accordance with
the provisions hereof. When any space on the third floor of the Building becomes available, Sublessor shall give Sublessee not less than thirty (30) days' prior written notice, which notice
shall identify the Expansion Space and the anticipated date the Expansion Space will be available for Sublessee's occupancy as set forth in this Sublease. Sublessee shall then have thirty
(30) days to negotiate an agreement with Sublessor on the rent and other business terms with respect to the Expansion Space. If Sublessor and Sublessee reach an agreement with respect to the
Expansion Space, (a) the Expansion Space will be deemed a part of the Subleased Premises and all of the terms and conditions of this Sublease shall apply to such Expansion Space, excluding the
agreed upon business terms for the Expansion Space, (b) the commencement date of the Sublease with respect to the Expansion Space shall be the later of (i) thirty (30) days after
Sublessor's initial notice to Sublessee notifying Sublessee that space on the third floor of the Building has become available or (ii) the date the Expansion Space is vacated (the "Effective
Date"), and (c) the Security Deposit will increase in proportion to the increase in Rent and Sublessee shall provide Sublessor with a replacement letter of credit in the new amount of the
Security Deposit prior to the Effective Date. The rights of Sublessee under this Paragraph 30 shall be subject to the following conditions: (x) that at the time Sublessee exercises its
rights hereunder (i) the Prime Lease is in full force and effect; (ii) this Sublease is in full force and effect without default on the part of Sublessee hereunder; and (iii) the
Sublessee originally named hereunder shall be in actual occupancy of 100% of the Subleased Premises; and (y) prior to the Effective Date Sublessee shall deliver to Sublessor a replacement
letter of credit in the new amount of the Security Deposit. If Sublessor and Sublessee do not reach an agreement within thirty (30) days after the Expansion Space "becomes available", Sublessor
shall have the right to sublease the subject Expansion Space to a third party on any terms Sublessor deems appropriate, to reoccupy the Expansion Space or to leave the Expansion Space vacant. 

        31.    Termination Right.    During the Term, if Sublessor is unable to accommodate Sublessee's expansion needs within
the Building, if any, with space that is adjacent to or in close proximity to the Subleased Premises and subject to Sublessee's reasonable approval or if Sublessor and Sublessee fail to reach
agreement after Sublessor notifies Sublessee that certain Expansion Space has become available, then Sublessee shall have a one time right to terminate this Sublease on the date that is twenty-seven
(27) months after the Commencement Date (the "Early Termination Date"), provided that Sublessee provides Sublessor with written notice given at least six (6) months prior to the Early
Termination Date. If the Sublessee elects to terminate this Sublease in accordance with this Paragraph 31, Sublessee shall pay to Sublessor on or before the Early Termination Date an amount
equal to all unamortized transactions costs (including reasonable attorneys' fees, brokerage commissions and the cost of Sublessor's Work, but excluding the free rent) with respect to this Sublease
plus one month's Rent,
which amount shall not exceed $70,000.00. Sublessor shall, within sixty (60) days following the Commencement Date hereof, deliver a statement to Sublessee certifying to Sublessee all actual
out-of-pocket transaction costs relating to this Sublease. In the event of such election by Sublessee, this Sublease shall terminate on the Early Termination Date as if the
Early Termination Date were the Expiration Date hereof. 

        32.    Hazardous Materials.    Sublessee shall not cause or permit any hazardous or toxic wastes, hazardous or toxic
substances or hazardous or toxic materials (collectively, "Hazardous Materials") to be used, generated, stored or disposed of on, under or about, or
transported to or from, the Subleased Premises (collectively, "Hazardous Materials Activities"), except in compliance with all applicable Regulations
and the Prime Lease, provided that Sublessee provides Sublessor with prior notification of such Hazardous Materials before using, storing or disposing of the same in, on, under or about the Subleased
Premises. If Sublessor consents to any such Hazardous Materials Activities, the Sublessee shall conduct them in compliance (at Sublessee's expense) with all applicable Regulations, as 

16

 

hereinafter
defined, and use all necessary and appropriate precautions to prevent any spill, discharge, release or exposure to persons or property. Sublessor shall not be liable to Sublessee for any
loss, cost, expense, claim, damage or liability arising out of any Hazardous Materials Activities by Sublessee, Sublessee's employees, agents, contractors, licensees, customers or invitees, whether or
not consented to by the Sublessor. For purposes hereof, Hazardous Materials shall include, but not be limited to, (i) substances defined as "hazardous
substances", "toxic substances", or "hazardous wastes" in (a) the federal
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, (b) the federal Hazardous Materials Transportation Act, as amended, (c) the federal Resource
Conservation and Recovery Act, as amended ("RCRA"); (ii) those substances defined as "hazardous
wastes" in the Massachusetts Hazardous Waste Facility Siting Act, as amended (Massachusetts General Laws Chapter 21D); (iii) those substances defined as
"hazardous materials" or "oil" in Massachusetts General Laws Chapter 21E, as amended; (iv) those
substances regulated by any other federal, state, county, municipal or local laws relating to the environment or health and human safety (whether now existing or hereinafter enacted or promulgated);
and (v) such substances as are defined in any regulations adopted and publications promulgated pursuant to any of said laws (collectively,
"Regulations"). Sublessor hereby consents to Sublessee's use of the Hazardous Materials listed on  Exhibit E attached hereto and to normal
quantities of cleaning fluid and office supplies which may constitute Hazardous Materials but which are
customarily present in premises devoted to office use, provided that such use is in compliance with all Regulations and shall be subject to all of the other provisions of this Paragraph 32,
except that Sublessee shall not be required to provide Sublessor with the aforesaid list of the types and quantities of such cleaning fluids and office supplies. Sublessee shall also provide Sublessor
with a copy of any Hazardous Materials inventory statement required by any applicable Regulations, and any update filed in accordance with any applicable Regulations. If Sublessee's activities violate
or create a risk of violation of any Regulations or cause a spill, discharge, release or exposure to any persons or property, Sublessee shall cease such activities immediately upon notice from
Sublessor. Sublessee shall immediately notify Sublessor both by telephone and in writing of any spill, discharge, release or exposure of Hazardous Materials in or about the Subleased Premises or of
any condition in or about the Subleased Premises constituting an "imminent hazard" under any Regulations. After giving reasonable notice, except in the
event of an emergency, Sublessor and Sublessor's representatives and employees may enter the Subleased Premises when accompanied by a representative of Sublessee at any time during the Term to inspect
Sublessee's compliance herewith, and may disclose any spill, discharge, release, or exposure or any violation of any Regulations to any governmental agency with jurisdiction. 

        Sublessee
hereby agrees to defend, indemnify and hold harmless Sublessor, its directors, partners, employees, agents, contractors, subcontractors, licensees, invitees, successors and
assigns from and against any and all liability, claims, suits, demands, judgments, costs, losses, interest and expenses (including, without being limited to, reasonable attorneys' fees and expenses
incurred in the investigation, defense and settlement of claims or remediation of contamination) incurred by such indemnified parties as a result of or in connection with Sublessee's use of Hazardous
Materials (except for Hazardous Materials or Wastes existing at the Subleased Premises prior to the date of this Sublease) or as a result of or in connection with activities prohibited under this
Paragraph 32. Sublessee shall bear, pay and discharge, as and when the same become due and payable, any and all such judgments or claims for damages, penalties or otherwise against such
indemnified parties, shall hold such indemnified parties harmless against all claims, losses, damages, liabilities, costs and expenses, and shall assume the burden and expense of defending all suits,
administrative proceedings, and negotiations of any description with any and all persons, political subdivisions or government agencies arising out of any of the occurrences set forth in this
Paragraph 32.

charges assessed or imposed on the Land for the then current calendar year by any governmental authority attributable to the Building ((including personal property associated therewith). The amount of
any special taxes, special assessments and agreed or governmentally imposed "in lieu of tax" or similar charges shall be included in Landlord's Taxes for any year but shall be limited to the amount of
the installment (plus any interest, other than penalty interest, payable thereon) of such special tax, special assessment or such charge required to be paid during or with respect to the year in
question. Landlord's Taxes include expenses, including reasonable fees of attorneys, appraisers and other consultants, incurred in connection with any efforts to obtain abatements or reduction or to
assure maintenance of Landlord's Taxes for any year wholly or partially included in the Term, whether or not successful and whether or not such efforts involved filing of actual abatement applications

excise or similar tax, assessment, levy, charge or fee measured by or based, in whole or in part, upon Building valuation, gross rents or other measures of building operations or benefits of
governmental services furnished to the Building, then any and all of such taxes, assessments, levies, charges and fees, to the extent so measured or based, shall be included within the term Landlord's
Taxes, but only to the extent that the same would be payable if the Building and Land were the only property of Landlord.

Premises are being leased in their "as-is" condition without representation or warranty by Landlord, and Landlord shall not be required to perform any work in connection
with Tenant's occupancy of the Premises, except that Landlord shall, prior to the Premises A Delivery Date, remove the free standing equipment from the cafeteria area. Landlord shall reimburse Tenant

this Lease but without payment of rent, to perform such work or decoration as is to be performed by, or under the direction

ARTICLE IV    
    
    LANDLORD'S COVENANTS

        4.1.1    BUILDING SERVICES.    Landlord shall furnish services, utilities, facilities and supplies set forth in this
Section 4.1.1 and in Exhibit D. Exhibit D is intended to add detail to the provisions of the main body of the Lease, and in case of conflict, the provisions of the main body of
the Lease shall control. Tenant may obtain additional services, utilities, facilities and supplies from time to time upon reasonable advance request or Landlord may furnish the same without request if
Landlord determines that Tenant's use or occupancy of the Premises necessitates the same (for example where the condition of the Premises necessitates additional cleaning services), and, in either
case, the cost of the same at reasonable rates from time to time established by Landlord shall constitute additional charges due by Tenant hereunder, payable upon billing. 

        4.1.1.1    WATER CHARGES.    Landlord shall furnish hot and cold water for ordinary office cleaning, toilet, lavatory
and drinking purposes. If Tenant requires, uses or consumes water for any other purpose, Landlord may assess on Tenant reasonable charges for additional water.

the Building on Mondays through Fridays excepting legal holidays, a list of which is attached as Exhibit C from 8:00 a.m. to 6:00 p.m. and on Saturdays

non-exclusive use at all other times. 

        4.1.1.3    CLEANING.    Landlord shall cause the common areas of the Building to be kept reasonably clean and in the
condition of a first-class office building in the greater Boston "Metro West" area, and Tenant shall provide all janitorial services to the Premises and shall keep, maintain, and repair the Premises
in good order. Cleaning standards shall be in accordance with Exhibit D. 

        4.1.1.4    HEAT AND AIR-CONDITIONING.    Landlord shall, through the Building heating and
air-conditioning system, furnish to and distribute in the Premises twenty-four (24) hours per day, seven (7) days per week, heat during the normal heating season
and air-conditioning when air-conditioning may reasonably be required for the comfortable occupancy of the Premises by Tenant. Landlord shall not be required to furnish heat
and air-conditioning in the Premises in excess of the capacity of the equipment presently installed in the Building. If Tenant requires additional air-conditioning for business
machines, meeting rooms or other purposes, or because of occupancy or unusual electrical loads, any additional air-conditioning units, chillers, condensers, compressors, ducts, piping and
other equipment and facilities will be installed and maintained by Landlord at Tenant's sole cost, but only to the extent that the same are compatible with the Building and its mechanical systems. 

        4.1.1.5    ENERGY CONSERVATION.    Tenant agrees to cooperate with Landlord and to abide by all
non-discriminatory Building regulations which Landlord may, from time to time, prescribe for the proper functioning and protection of the heating and air-conditioning systems
and in order to maximize the effect thereof and to conserve heat and air-conditioning so long as such regulations do not materially interfere with the Tenant's use and occupancy of the
Premises. Notwithstanding anything to the contrary in this Section 4.1.1 or otherwise in this Lease, Landlord may institute such policies, programs and measures as may be in Landlord's
reasonable judgment necessary, required or expedient for the conservation or preservation of energy or energy services, or as may be necessary to comply with applicable codes, rules, regulations or
standards. 

        4.1.2    REPAIRS.    Except as otherwise provided in this Lease, and except for repairs to items referred to below
necessitated by Tenant's act or neglect (which cost thereof shall be Tenant's obligation under Section 5.1), Landlord shall maintain repair and replace the roofs, foundations, exterior walls,
exterior windows, floor slabs, core walls, building systems and common areas and facilities in the Building as may be necessary to keep them in good condition. 

        4.1.3    QUIET ENJOYMENT.    Landlord covenants that Tenant, on paying the rent and performing the tenant obligations
in this Lease, shall peacefully and quietly have, hold and enjoy the Premises, free from any claim by Landlord or persons claiming under Landlord, but subject to all of the terms and provisions
hereof, provisions of law and rights of record to which this Lease is or may become subordinate. This covenant is in lieu of any other so-called quiet enjoyment covenant, either express or
implied. 

        4.1.4    BUILDING SYSTEMS.    Landlord covenants that all systems in the Building, including, but not limited to,
HVAC, elevator services, water and sewer, parking and all fixtures and equipment in the Premises, including, but not limited to, those used for laboratory or research and development purposes, shall
be in good working order and condition as of the Delivery Date of Premises A for Premises A and as of the Delivery Date for Premises B for Premises B.

        4.2    INTERRUPTION    

        Landlord
shall not be liable to Tenant for any compensation or reduction of rent by reason of inconvenience or annoyance or for loss of business arising from the necessity of Landlord or
its agents entering the Premises for any of the purposes authorized in this Lease or for repairing the Premises or from repairs by Landlord of any portion of the Building however the necessity may
occur. In case Landlord is prevented or delayed from diligent construction of improvements, making any repairs, alterations or improvements, or furnishing any services or performing any other covenant
or duty to be performed on Landlord's part, by reason of any cause reasonably beyond Landlord's control, Landlord shall not be liable to Tenant therefor, nor, except as otherwise provided in this
Section 4.2 below, and in Section 6.1, shall Tenant be entitled to any abatement or reduction of rent by reason thereof, nor shall the same give rise to a claim in Tenant's favor that
such failure constitutes actual or constructive, total or partial, eviction from the Premises. In no event shall Landlord be liable for indirect or consequential damages arising out of any default by
Landlord or otherwise. 

        Landlord
reserves the right to stop any service or utility system, when necessary by reason of accident or emergency, or until necessary repairs have been completed; provided, however,
that in each instance of stoppage, Landlord shall exercise reasonable diligence to eliminate the cause thereof. Except in case of emergency repairs, Landlord will give Tenant reasonable advance notice
of any contemplated stoppage and will use reasonable efforts to avoid unnecessary interruption of Tenant's use of the Premises by reason thereof. 

        The
foregoing notwithstanding, if Landlord fails for any reason within Landlord's control to provide any service to be supplied by Landlord under the Lease which is necessary for
Tenant's reasonable use of the Premises (such as HVAC, elevator service, electricity, water, or structural repairs), and Tenant is unable to use the Premises on account of such failure, Tenant shall
be entitled to a proportional abatement of Annual Fixed Rent and Additional Rent based on the portion of the Premises which is not used by Tenant, unless Landlord cannot repair such services or
utility systems due to force majeure or delays caused by Tenant. This abatement shall begin on the thirtieth (30th) consecutive business day from Tenant's written notice to Landlord of
the failure. The abatement shall end when the services are restored sufficient to permit use of the Premises. 

        4.3.    INSURANCE AND INDEMNITY    

        4.3.1    Property Insurance.    Landlord agrees to maintain throughout the Term, with companies licensed and approved
to write insurance in Massachusetts, property insurance against direct physical loss or damage
to the Building on an "all risks," agreed amount basis in an amount required by Landlord's mortgagee (currently, the full replacement value of the Building). Landlord shall not be required to carry
insurance with respect to any property which Tenant is required to insure pursuant to Section 5.5. 

        4.3.2    Liability Insurance.    Throughout the Term, Landlord shall maintain in a responsible company or companies
liability insurance against claims, demands or actions for injury, death, and property damage in amounts not less than $3,000,000 in the aggregate. 

        4.3.3    Indemnity.    Landlord shall save Tenant and its agents and employees harmless and indemnified (and shall
defend the same) against any claim, loss or cost to the extent arising out of the negligence or willful misconduct of Landlord or its agents, employees, or contractors. 

        4.4    HAZARDOUS MATERIALS    

        Landlord
represents that, to the best of Landlord's knowledge, based on the Baseline Assessment performed in connection with this Lease, the Premises and Building do not contain any
friable asbestos, oil or other hazardous material, except as set forth in the Baseline Assessment, and there has not been any oil or hazardous materials released on the Land which requires remediation
or removal under 

8

 

Massachusetts
General Laws Chapter 21E. If Landlord shall learn of any such release after the date of this Lease, Landlord shall undertake, at no cost to Tenant, or cause the responsible parties to
undertake, remediation or removal actions as required by applicable law, subject in all events to Section 5.2 below. 

 
 

ARTICLE V    
    
    TENANTS ADDITIONAL COVENANTS    
    

        5.1    MAINTENANCE AND REPAIR    

        Except
for damage by fire or casualty and reasonable wear and tear, Tenant shall at all times keep the Premises clean, neat and in as good repair, order and condition as the same are at
the beginning of the Term or may be put in thereafter. The foregoing shall include without limitation Tenant's obligation to maintain floors and floor coverings, to paint and repair interior walls and
doors, to replace and repair ceiling tiles, lights and light fixtures, drains and the like, not part of the common facilities and clean the Premises to the extent such cleaning is not to be performed
by Landlord under Exhibit D. 

        5.2    USE, WASTE AND NUISANCE    

        Throughout
the Term, Tenant shall use the Premises for the Permitted Uses only, and shall not use the Premises for any other purpose. Tenant shall not injure, overload, deface or commit
waste in the Premises or any part of the improvement on the Land, nor permit the emission therefrom of any objectionable noise, light or odor, nor use or permit any use of the Premises which is
contrary to law or ordinance or which is liable to invalidate or increase the premium for any insurance on the Building or its contents or which is liable to render necessary any alterations or
additions in the Building, except as permitted pursuant to Section 5.9, nor obstruct in any manner any portion of the Building. If Tenant's use of the Premises results in an increase in the
premium for any insurance on the Building or the contents thereof, Landlord shall notify Tenant of such increase and Tenant shall pay same as additional charges. Tenant may not without Landlord's
consent install in the Premises any pay telephones, vending machines, water fountains, refrigerators, sinks or cooking equipment provided that Landlord's consent will not be unreasonably withheld with
respect to items designed for the convenience of Tenant's employees which are customary for office employees or laboratory use. 

        Tenant
shall not (either with or without negligence) cause or permit the escape, disposal or release of any biologically or chemically active or other hazardous substances, or materials.
Tenant shall not allow the storage or use of such substances or materials in any manner not sanctioned by law or by the highest standards prevailing in the life sciences industry (which are applicable
to the Building) for the storage and use of such substances or materials, nor allow to be brought into the Building any such materials or substances except to use in the ordinary course of Tenant's
business, and after written notice is given to Landlord of the identity of such substances or materials as provided herein. Prior to the Premises A Rent Commencement Date, Tenant shall provide
Landlord with copies of all applicable permits in connection with Tenant's use in, on or around the Premises of hazardous substances or any other substances regulated under Federal, state or local
law. On the anniversary date of each Lease Year, Tenant shall annually certify to Landlord the type and quantity of hazardous substances used in, on or around the Premises. Without limitation,
hazardous substances and materials shall include those described in the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, 42 U.S.C. §9601 et seq.,
the Resource Conservation and Recovery Act, as amended, 42 U.S.C. §6901 et seq., the Massachusetts Hazardous Waste Management Act, as amended, M.G.L. Chapter 21C, and the Massachusetts Oil
and Hazardous Material Release Prevention Act, as amended, M.G.L. Chapter 2 IE, and the regulations adopted under these acts. If any lender or governmental agency shall ever require testing to
ascertain whether or not there has been any release of hazardous materials, then the reasonable costs thereof shall be reimbursed by Tenant to Landlord upon demand as additional charges if such
requirement applies to the Premises, and if the requirement applies to the 

9

 

Building
generally, then such costs shall be included in Landlord's Operating Expenses. In addition, Tenant shall execute affidavits, representations and the like from time to time at Landlord's
reasonable request concerning Tenant's best knowledge and belief regarding the presence of hazardous substances or materials on the Premises. In all events, Tenant shall indemnify Landlord in the
manner elsewhere provided from any release of hazardous materials on the Premises occurring while Tenant is in possession of the Premises, or elsewhere if caused by Tenant or persons acting under
Tenant. 

        5.3    RULES AND REGULATIONS    

        Tenant
shall conform to all reasonable non-discriminatory rules and regulations now or hereafter promulgated by Landlord for the care and use of the Premises and the Building
and attached hereto as Exhibit G. If there is a conflict between such rules and regulations and the Lease, the terms of the Lease shall prevail. 

        5.4    SAFETY APPLIANCES    

        Tenant
shall keep the Premises equipped with all safety appliances and permits which, as a result of Tenant's particular activities, are required by law or ordinance or any order or
regulation of any public authority, shall keep the Premises equipped at all times with adequate fire extinguishers and other such
equipment reasonably required by Landlord, and, subject to Section 5.10, shall make all repairs, alterations, replacements, or additions so required as a result of Tenant's particular
activities. 

        5.5    INDEMNIFICATION AND INSURANCE    

        Tenant
shall save Landlord, its mortgagees, agents, employees, independent contractors, invitees, and any other parties reasonably designated by Landlord from time to time (collectively,
the "Indemnitees") harmless and indemnified (and shall defend the Indemnitees with counsel reasonably approved by the Indemnitees) against any claim, loss or cost arising in whole or in part out of
any injury, loss, theft or damage to any person or property while on or in the Premises, or in transit thereto or therefrom, or out of any condition within or around the Premises, except to the extent
arising from the negligence or willful misconduct of the Indemnitees, and to any person or property anywhere occasioned by any act, omission, neglect or default of Tenant or of employees, agents,
independent contractors or invitees of Tenant or any person acting under Tenant. In addition to the foregoing, Landlord may make all repairs and replacements to the improvements on the Land resulting
from acts or omissions of Tenant's employees, agents, independent contractors or invitees or any other persons acting under Tenant (including damage and breakage occurring as a result of work
performed by or for Tenant and when Tenant's property is being moved into or out of the Building) and Landlord may recover all reasonable costs and expenses thereof from Tenant as additional charges.
Throughout the Term (and such earlier or further time as Tenant or any person claiming through Tenant enters upon or occupies any part of the Premises whether pursuant to a license or otherwise)
Tenant shall maintain in a responsible company or companies approved by Landlord, liability insurance in form satisfactory to Landlord (which may be in the form of an umbrella policy containing an
agreed-upon amount endorsement specific to the Premises), written on an occurrence basis, insuring the Indemnitees and other parties designated by Landlord, and Tenant, as their respective
interests may appear, against all claims, demands or actions for injury, death, and property damage in amounts not less than those specified in Section 1.1 (as such amounts may, from time to
time, be reasonably increased by Landlord). All insurance to be maintained by Tenant under this Section 5.5 shall provide that it will not be subject to cancellation, termination, or change
except after at least 30 days' prior written notice to the Indemnitees and other parties designated by Landlord. The policy or policies or a duly executed certificate or certificates for the
same (together with satisfactory evidence of the payment of the premium thereon if requested by Landlord) shall be deposited with Landlord and other parties designated by Landlord at the beginning of
the Term and, upon renewals of such policies, not less than 30 days prior to the expiration of the term of such coverage. If Tenant fails to comply with any of the foregoing requirements,
Landlord may obtain such insurance on behalf of Tenant and may keep the 

10

 

same
in effect, and Tenant shall pay Landlord, as additional charges (which shall constitute rent hereunder), the premium cost thereof upon demand. The covenants of this Section 5.5 shall
survive the expiration of the Term or earlier termination of this Lease. 

        5.6    TENANT'S PROPERTY    

        All
furnishings, fixtures, equipment, effects and property of Tenant and of all persons claiming through Tenant which from time to time may be on the Premises or elsewhere in the
Building or in transit thereto or therefrom shall be at the sole risk of Tenant and shall be kept insured by Tenant throughout the term at Tenant's expense and in prudent amounts, and if the whole or
any part thereof shall be destroyed or damaged by fire, water or otherwise, or by the leakage or bursting of water pipes, steam pipes, or other pipes, by theft or from any other cause, no part of said
loss or damage is to be charged to or be borne by Landlord. 

        5.7    ENTRY FOR REPAIRS AND INSPECTIONS    

        Tenant
shall permit Landlord and its agents to enter and examine the Premises at reasonable times and upon prior notice to Tenant, except in an emergency and, if Landlord shall so elect,
to make any repairs or replacements Landlord may deem necessary or desirable, to remove at Tenant's expense any alterations, additions, signs, curtains, blinds, shades, awnings, aerials, flagpoles, or
the like not consented to in writing (to the extent such consent is required by this Lease), and to show the Premises to prospective tenants during the eighteen months preceding expiration of the Term
and to prospective purchasers and mortgagees at all times. In case of an emergency in the Premises or in the Building, Landlord or its representative may enter the Premises (forcibly, if necessary) at
any time to take such measures as may be needed to deal with such emergency. 

        5.8    ASSIGNMENT, SUBLETTING    

        Tenant
shall not assign this Lease, or sublet or license the Premises or any portion thereof, or permit the occupancy of all or any portion of the Premises by anybody other than Tenant
(all or any of the foregoing actions are referred to as "Transfers" and all or any of assignees, subtenants, licensees, and other such parties are referred to as "Transferees") without obtaining, on
each occasion, the prior consent of the Landlord, which consent shall not be unreasonably withheld. Notwithstanding the provisions of this Section 5.8, this Lease may be assigned, or the
Premises may be sublet, in whole or in part, after prior notice to Landlord but without consent of the Landlord and without any termination right of the Landlord being applicable thereto,
(i) to any corporation or other entity into or with which Tenant may be merged or consolidated or to any corporation or entity to which all or substantially all of the 

        If
Tenant enters into any Transfer with respect to the Premises (or any part thereof), Landlord may, at any time and from time to time, require that such Transferee agree directly with
Landlord to be liable, jointly and severally with Tenant, to the extent of the obligation undertaken by or attributable to such Transferee, for the performance of Tenant's agreements under this Lease
(including payment of rent and other charges under the Transfer), and every Transfer shall so provide, without relieving or modifying Tenant's liability hereunder. Landlord may collect rent and other
charges from the Transferee and apply the net amount collected to the rent and other charges hereunder, but no such assignment or collection shall be deemed a waiver of the provisions of
Section 5.8, or the acceptance of the Transferee, as a tenant, or a release of Tenant from direct and primary liability for the further performance of Tenant's covenants hereunder. The consent
by Landlord to a particular Transfer shall not relieve Tenant from the requirement of obtaining the consent of Landlord to any further Transfer. 

        5.9    ALTERATIONS    

        Tenant
shall make no alterations, additions or improvements to the Premises without the prior written consent of Landlord and only in accordance with complete construction documents
approved in 

11

 

advance
by Landlord. Notwithstanding the foregoing, after notice to Landlord but without any requirement for Landlord's consent (except in connection with approval of Tenant's contractors), Tenant may
perform cosmetic alterations in the Premises which do not affect the Building's structure or base building systems and costs no more than fifty thousand dollars ($50,000.00) in the aggregate for a
single project. All such alterations, additions and improvements shall be done only by contractors approved in advance by Landlord. Tenant shall obtain all necessary permits before undertaking any
such alterations, additions or improvements and shall carry such insurance and obtain such payment, performance and lien bonds as Landlord shall reasonably require. Any alterations, additions and
improvements to the Premises, except movable furniture and trade fixtures, shall belong to Landlord upon the expiration or early termination of the Lease. All alterations, additions and improvements
to the Premises shall be at Tenant's sole cost. If any mechanic's lien (which term shall include all similar liens relating to the furnishing of labor and materials) is filed against the Building
which is claimed to be attributable to Tenant, its agents, employees or contractors, Tenant shall give immediate notice of such lien to Landlord and shall discharge the same by payment or filing any
necessary bond within 10 days after Tenant has notice (from any source) of such lien. Landlord's approval of the construction documents shall signify Landlord's consent to the work shown
thereon only and Tenant shall be solely responsible for any errors or omissions contained therein. Landlord's consents and approvals under this Section 5.9 shall not be unreasonably withheld or
delayed. 

        5.10    SURRENDER    

        At
the expiration of the Term or earlier termination of this Lease, without the requirement of any notice, Tenant shall peaceably surrender the Premises including all improvements
thereto and all replacements thereof, including carpeting, any water or electricity meters, supplementary electrical and HVAC equipment, and all fixtures and partitions, in any way bolted or otherwise
attached to the Premises (which shall become the property of Landlord) except such items as Landlord shall direct Tenant to remove, the Premises and improvements to be in the condition in which the
same are required to be maintained under Section 5.1. Prior to the surrender of the Premises, Tenant shall perform a final assessment similar in scope to the Baseline Assessment performed
pursuant to Section 2.4 ("Final Assessment"). If the Final Assessment reveals any Hazardous Materials not required by law to be removed or abated (for example, because the amount, type or level
of Hazardous Materials falls below regulation under law), at surrender, Tenant shall not be required to remove such Hazardous Materials, provided, that
such amount, type or levels of Hazardous Materials has not changed since the date of the Baseline Assessment, and if the amount or levels of Hazardous Materials outlined in the Baseline Assessment has
increased since the Baseline Assessment, Tenant shall cause the clean-up and removal of such Hazardous Materials to those levels set forth in the Baseline Assessment. Tenant shall, at the
time of surrender, remove only those improvements, goods, effects and fixtures (including cabling) which (i) Landlord directs Tenant to remove as provided in this Section 5.10 at the
time Tenant installs such improvements, goods, effects and fixtures, provided that Landlord has received notice and information with respect to such installation and (ii) such improvements
listed on Exhibit H (Tenant's Personal Property). Tenant shall make any repairs to the Premises and other areas necessitated by such removal and leave the Premises clean and tenantable. Should
Tenant fail to remove any of such goods, effects, and fixtures, Landlord may have them removed forcibly, if necessary, and store any of Tenant's property in a public warehouse at the risk of Tenant.
If such items are not removed from storage within thirty (30) days, such items may be sold by any customary methods in order to pay storage costs and other expenses of Landlord. The expense of
such removal, storage and reasonable repairs necessitated by such removal shall be borne by Tenant or reimbursed by Tenant to Landlord. 

12

 

        5.11    PERSONAL PROPERTY TAXES    

        Tenant
shall pay promptly when due all taxes (and charges in lieu thereof) imposed upon Tenant's personal property in the Premises, no matter to whom assessed (including, without
limitation, fixtures and equipment). 

 
 

ARTICLE VI    
    
    CASUALTY AND TAKING    
    

        6.1    DAMAGE BY FIRE OR CASUALTY    

        If
the Premises or any part thereof shall be damaged by fire or other insured casualty, then, subject to the last paragraph of this Section 6.1, Landlord shall proceed with
diligence, subject to then applicable statutes, building codes, zoning ordinances and regulations of any governmental authority, and at the expense of Landlord (but only to the extent of insurance
proceeds made available to Landlord by any mortgagee of the Building) to repair or cause to be 

Fixed
Rent and additional charges for Landlord's Operating Expenses shall be abated for the remainder of the Term. 

        If
the entire Premises or the portions of the Building required for reasonable access to, or the reasonable use of, the Premises are taken by eminent domain, this Lease shall
automatically end on the earlier of: (i) the date title vests; or (ii) the date Tenant is dispossessed by the condemning authority. 

        If
the taking of a part of the Premises materially interferes with Tenant's ability to continue its business operations then Tenant may end this Lease on the earlier of: (i) the
date when title vests; (ii) the date Tenant is dispossessed by the condemning authority; or (iii) sixty (60) days following notice to Tenant of the date when vesting or
dispossession is to occur. If there is a partial taking and this Lease continues, then the Lease shall end as to the part taken and the Annual Fixed Rent shall abate in proportion to the part of the
Premises taken. 

        6.3    EMINENT DOMAIN AWARD    

        Landlord
reserves to itself any and all rights to receive awards made for damages to the Premises, the Building or the leasehold hereby created, or any one or more of them, accruing by
reason of exercise of eminent domain or by reason of anything lawfully done in pursuance of public or other authority. Tenant hereby releases and assigns to Landlord all Tenant's rights to such
awards, and covenants to deliver such further assignments and assurances thereof as Landlord may from time to time request.
Tenant shall be entitled to claim and retain amounts which may be awarded to Tenant (specifically so designated by the court or authority having jurisdiction over the matter) in any condemnation
proceedings due to the taking of its trade fixtures, leasehold improvements, loss of its leasehold estate, relocation expenses, goodwill and such business loss as Tenant shall separately and
specifically establish. Landlord agrees that it shall not discriminate against Tenant in the exercise of any right to terminate this Lease in the event of a condemnation or eminent domain taking. 

 
 

ARTICLE VII    
    
    DEFAULT    
    

        7.1    TERMINATION FOR DEFAULT OR INSOLVENCY    

        This
Lease is upon the condition that (1) if Tenant shall fail to perform or observe any of Tenant's covenants, and if such failure shall continue, (a) in the case of rent
or payment of additional charges or any sum due Landlord hereunder, for more than ten (10) days after such payment is due, or (b) in any other case, after notice, for more than thirty
(30) days (provided that if correction of any such matter reasonably requires longer than 30 days and Tenant so notifies Landlord within 20 days after 

13

 

Landlord's
notice is given together with an estimate of time required for such cure, Tenant shall be allowed such longer period, but only if cure is begun within such 30-day period and
such delay does not cause increased risk of damage to person or property), or (2) if three or more notices under clause (1) hereof are given in any twelve month period (failure to pay
rent or any other sum for more than 3 days after the particular due date shall have the same effect under this clause (2) as such a notice); (3) if the leasehold hereby created
shall be taken on execution, or by other process of law, or if any assignment shall be made of Tenant's property for the benefit of creditors; or (4) if a receiver, guardian, conservator,
trustee in bankruptcy or similar officer shall be appointed by a court of competent jurisdiction to take charge of all or any part of Tenant's property and such appointment is not discharged within
90 days thereafter or if a petition including, without limitation, a petition for reorganization or arrangement is filed by Tenant under any bankruptcy law or is filed against Tenant and not
dismissed within 90 days from the date upon which it is filed, then, and in any of said cases, Landlord may, immediately or at any time thereafter, elect to terminate this Lease by notice of
termination, by entry, or by any other means available under law and may recover possession of the Premises as provided herein. Upon termination by notice, by entry, or by any other means available
under law, Landlord shall be entitled immediately, in the case of termination by notice or entry, and otherwise in accordance with the provisions of law to recover possession of the Premises from
Tenant and those claiming through or under the Tenant. Such termination of this Lease and repossession of the Premises shall be without prejudice to any remedies which Landlord might otherwise have
for arrears of rent or for a prior breach of the provisions of this Lease. Tenant waives any statutory notice to quit and equitable rights in the nature of further cure or redemption, and Tenant
agrees that upon Landlord's termination of this Lease Landlord shall be entitled to re-entry and possession in accordance with the terms hereof. Landlord may, without notice, store
Tenant's personal property (and those of any person claiming under Tenant) at the expense and risk of Tenant or, if Landlord so elects, Landlord may sell such personal property at public auction or
auctions or at private sale or sales after seven days notice to Tenant and apply the net proceeds to the earliest of installments of rent or other charges owing Landlord. Tenant agrees that a notice
by Landlord alleging any default shall, at Landlord's option (the exercise of such option shall be indicated by the inclusion of the words "notice to quit" in such notice), constitute a statutory
notice to quit. If Landlord exercises its option to designate a notice of default hereunder as a statutory notice to quit, any grace periods provided for herein shall run concurrently with any
statutory notice periods. Landlord and Tenant waive trial by jury in any action to which they are parties. Tenant further agrees that it shall not interpose any non-compulsory counterclaim
or set-off in any summary proceeding or in any action based in whole or in part on non-payment of rent. 

        7.2    REIMBURSEMENT OF LANDLORD'S EXPENSES    

        In
the case of termination of this Lease pursuant to Section 7.1, Tenant shall reimburse Landlord for all reasonable expenses arising out of such termination, including without
limitation, all costs incurred in collecting amounts due from Tenant under this Lease (including attorneys' fees, costs of litigation and
the like); all reasonable expenses incurred by Landlord in attempting to relet the Premises or parts thereof (including advertisements, brokerage commissions, Tenant's allowances, costs of preparing
space, and the like); all of Landlord's then unamortized costs of special inducements provided to Tenant (including without limitation rent holidays, rent waivers, above building standard leasehold
improvements, and the like) and all Landlord's other reasonable expenditures necessitated by the termination. The reimbursement from Tenant shall be due and payable immediately from time to time upon
notice from Landlord that an expense has been incurred, without regard to whether the expense was incurred before or after the termination. 

        7.3    DAMAGES    

        In
the event of the termination of this Lease by Landlord, Landlord may elect by written notice to Tenant within one year following such termination to be indemnified for loss of rent by
a lump sum 

14

 

payment
representing the then present value of the amount of rent and additional charges which would have been paid in accordance with this Lease for the remainder of the Term or the Extension Term,
as the case may be, minus the then present value of the aggregate fair market rent and additional charges payable for the Premises for the remainder of the Term or the Extension Term, as the case may
be; (if less than the rent and additional charges payable hereunder), estimated as of the date of the termination, and taking into account reasonable projections of vacancy and time required to
re-lease the Premises; (For the purposes of calculating the rent which would have been paid hereunder for the lump sum payment calculation described herein, the last full year's additional
charges under Section 2.6 is to be deemed constant for each year thereafter. The Federal Reserve discount rate (or equivalent) shall be used in calculating present values.) Should the parties
be unable to agree on a fair market rent, the matter shall be submitted, upon the demand of either party, to the Boston, Massachusetts office of the American Arbitration Association, with a request
for arbitration in accordance with the rules of the Association by a single arbitrator who shall be an MAI appraiser with at least ten years experience as an appraiser of major office buildings in the
Greater Boston area and shall not have a prior relationship with either party. The parties agree that a decision of the arbitrator shall be conclusive and binding upon them. If, at the end of the
Term, the rent which Landlord has actually received from the Premises is less than the aggregate fair market rent estimated as aforesaid, Tenant shall thereupon pay Landlord the amount of such
difference. Should Landlord fail to make the election provided for in this Section 7.3, Tenant shall indemnify Landlord for the loss of rent by a payment at the end of each month which would
have been included in the Term, representing the difference between the rent which would have been paid in accordance with this Lease (Annual Fixed Rent under Section 2.5, and additional
charges which would have been payable under Section 2.6 to be ascertained monthly) and the rent actually derived from the Premises by Landlord for such month (the amount of rent deemed derived
shall be the actual amount less any portion thereof attributable to Landlord's reletting expenses described in Section 7.2 which have not been reimbursed by Tenant thereunder). 

        7.4    MITIGATION    

        Any
obligation under this Lease or otherwise imposed by law upon Landlord to relet the Premises shall be subject to the right of Landlord (and its affiliates) to lease other available
space in Hobbs Brook Office Park and to the reasonable requirements of Landlord to lease to high quality tenants and to lease the Building in a harmonious manner with an appropriate mix of uses,
tenants, floor areas and terms of tenancies, and the like. 

        7.5    CLAIMS IN BANKRUPTCY    

        Nothing
herein shall limit or prejudice the right of Landlord to prove and obtain in a proceeding for bankruptcy, insolvency, arrangement or reorganization, by reason of the termination,
an amount equal to the maximum allowed by a statute or law in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether or not the amount is greater to,
equal to, or less than the amount of the loss or damage which Landlord has suffered. 

        7.6    INTEREST ON UNPAID AMOUNTS    

        If
any payment of Annual Fixed Rent, additional charges, or other payment due from Tenant to Landlord is not paid when due, then without notice and in addition to all other remedies
hereunder, Tenant shall pay to Landlord interest on such unpaid amount equal to 1.5% of the amount in question for each month and for each part thereof during which said delinquency continues;
provided, however, in no event shall such interest exceed the maximum amount permitted to be charged by applicable law.

ARTICLE VIII    
    
    MISCELLANEOUS    
    

        8.1    HOLDOVER    

        If
Tenant remains in the Premises after the termination or expiration of the Term, such holding over shall be as a tenant at will or tenant by the month (requiring 30 days notice
of termination by either party to the other) at a monthly fixed rent equal to 1.5 times the Annual Fixed Rent due hereunder for the last month of the Term for the first sixty (60) days and
thereafter two times the Annual Fixed Rent, and otherwise subject to all the covenants and conditions (including obligations to pay additional charges under Section 2.6) of this Lease as though
it had originally been a monthly tenancy. Notwithstanding the foregoing, if Landlord desires to regain possession of the Premises promptly after the termination or expiration hereof and prior to
acceptance of rent for any period thereafter, Landlord may, at its option, forthwith re-enter and take possession of the Premises or any part thereof by any legal process in force in The
Commonwealth of Massachusetts. 

        Notwithstanding
the establishment of any holdover tenancy following the expiration or earlier termination of the Term, if Tenant fails promptly to vacate the Premises at the expiration
or earlier termination of the Term, Tenant shall save Landlord harmless and indemnified against any claim, loss, cost or expense (including reasonable attorneys' fees) arising out of Tenant's failure
promptly to vacate the Premises (or any portion thereof). 

        8.2    ESTOPPEL CERTIFICATES    

        At
Landlord's request, from time to time, Tenant agrees to execute and deliver to Landlord, within ten (10) business days after such request, a certificate which acknowledges the
dates on which the Term begins and ends, tenancy and possession of the Premises and recites such other facts concerning any provision of the Lease or payments made under the Lease which Landlord or a
mortgagee or lender or a purchaser or prospective purchaser of the Building or any interest therein or any other party may
from time to time reasonably request. Tenant acknowledges that the execution and delivery of such certificates in connection with a financing or sale in a prompt manner constitute requirements of
Landlord's financing and/or property dispositions. Without limitation of the foregoing, Tenant agrees to execute a document in the form of Exhibit E, or whatever other reasonable instruments
may be required by the first mortgagee or junior mortgagee to acknowledge such tenancy in a recordable form, within ten (10) business days after Landlord's request, correcting as appropriate
any representations which are not then correct. 

        8.3    NOTICE    

        Any
notice, approval, consent and other like communication hereunder from Landlord to Tenant or from Tenant to Landlord shall be effective only if given in writing and shall be deemed
duly served if and when hand delivered or if and when mailed prepaid certified mail or by a nationally recognized overnight carrier, (in any case, whether or not accepted for delivery). Communications
to Tenant shall be addressed to Tenant's Authorized Representative at the Original Address of Tenant set forth in Section 1.1 prior to the Term Commencement Date and thereafter at the Premises,
with a copy to: Thomas G. Schnorr, Esq., Palmer & Dodge LLP; address prior to November 1, 2001, One Beacon Street, Boston, MA 02108; address after November 1, 2001, 111 Huntington
Avenue, Boston, MA 02199. Communications to Landlord shall be addressed to the Address of Landlord set forth in Section 1.1. Either party may from time to time designate other addresses within
the continental United States by notice to the other. 

        8.4    LANDLORD'S RIGHT TO CURE    

        At
any time and with notice to Tenant (except in an emergency), Landlord may, but need not, cure any failure by Tenant to perform its obligations under this Lease. Whenever Landlord
chooses to do so, 

16

 

Tenant
shall pay all costs and reasonable expenses incurred by Landlord in curing any such failure, including, without limitation, reasonable attorneys' fees together with an administrative charge
equal to 15% of such costs and expenses (or such higher percentage as may then be customary with respect to first-class office buildings in the Greater Boston area) and interest as provided in
Section 7.6. 

        8.5    SUCCESSORS AND ASSIGNS    

        This
Lease and the covenants and conditions herein contained shall inure to the benefit of and be binding upon Landlord, its successors and assigns, and shall be binding upon Tenant, its
successors and assigns, and shall inure to the benefit of Tenant and only such Transferees of Tenant as are permitted
hereunder. The term "Landlord" means the original Landlord named herein, its successors and assigns. The term "Tenant" means the original Tenant named herein and its permitted successors and assigns. 

        8.6    BROKERAGE    

        Landlord
and Tenant each warrant to the other that it has had no dealings with any broker or agent in connection with this Lease or any other space in the Hobbs Brook Office Park except
for any brokers designated in Section 1.1. Landlord and Tenant hereby covenant to pay, hold harmless and indemnify the other from and against any and all costs, expense or liability for any
compensation, commissions and charges claimed by any broker or agent other than any such broker designated in Section 1.1 with respect to this Lease or the negotiation thereof arising from a
breach of the foregoing warranty. Landlord shall be responsible for payment of any brokerage commission to any broker designated in Section 1.1. 

        8.7    WAIVER    

        The
failure of Landlord or of Tenant to seek redress for violation of, or to insist upon strict performance of, any covenant or condition of this Lease, or, with respect to such failure
of Landlord, any of the Rules and Regulations referred to in Section 5.3, whether heretofore or hereafter adopted by Landlord, shall not be deemed a waiver of such violation nor prevent a
subsequent act, which would have originally constituted a violation, from having all the effect of an original violation, nor shall the failure of Landlord to enforce any of said Rules and Regulations
against any other tenant of the Building be deemed a waiver of any such Rules or Regulations. The receipt by Landlord of Annual Fixed Rent or additional charges with knowledge of the breach of any
covenant of this Lease shall not be deemed waiver of such breach. No provision of this Lease shall be deemed to have been waived by Landlord, or by Tenant, unless such waiver be in writing signed by
the party to be charged. No consent or waiver, express or implied, by Landlord or Tenant to or of any breach of any agreement or duty shall be construed as a waiver or consent to or of any other
breach of the same or any other agreement or duty. 

        8.8    ACCORD AND SATISFACTION    

        No
acceptance by Landlord of a lesser sum than the Annual Fixed Rent and additional charges then due shall be deemed to be other than on account of the earliest installment of such rent
and charges due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as rent be deemed an accord and satisfaction, and Landlord may accept such check or
payment without prejudice to Landlord's right to recover the balance of such installment or pursue any other remedy provided in this Lease. The delivery of keys to Landlord shall not operate as a
termination of this Lease or a surrender of the Premises. 

        8.9    REMEDIES CUMULATIVE    

        The
specific remedies to which Landlord may resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies to which it may be lawfully
entitled in case of any breach or threatened breach by Tenant of any provisions of this Lease. In addition to the other remedies provided in this Lease, Landlord shall be entitled to the restraint by
injunction of the 

17

 

violation
or attempted or threatened violation of any of the covenants or conditions of this Lease or to a decree compelling specific performance of any such covenants or conditions. 

        8.10    PARTIAL INVALIDITY    

        If
any term of this Lease, or the application thereof to any person or circumstance, shall to any extent be invalid or unenforceable, the remainder of this Lease, or the application of
such term to persons or circumstances other than those as to which it is invalid or unenforceable, shall not be affected thereby, and each term of this Lease shall be valid and enforceable to the
fullest extent permitted by law. 

        8.11    WAIVERS OF SUBROGATION    

        Any
insurance carried by either party with respect to the Premises or property therein or occurrences thereon shall, if it can be so written without additional premium or with an
additional premium which the other party agrees to pay, include a clause or endorsement denying to the insurer rights of subrogation against the other party to the extent rights have been waived by
the insured hereunder prior to occurrence of injury or loss. Each party, notwithstanding any provisions of this Lease to the contrary, hereby waives any rights of recovery against the other for injury
or loss due to hazards covered by such insurance to the extent of the indemnification received thereunder. 

        8.12    ENTIRE AGREEMENT    

        This
Lease contains all of the agreements between Landlord and Tenant with respect to the Premises and supersedes all prior writings and dealings between them with respect thereto. 

        8.13    NO AGREEMENT UNTIL SIGNED    

        The
submission of this Lease or a summary of some or all of its provisions for examination does not constitute a reservation of or option for the Premises or an offer to lease and no
legal obligations shall arise with respect to the Premises or other matters herein until this Lease is executed and delivered by Landlord and Tenant. 

        8.14    TENANT'S AUTHORIZED REPRESENTATIVE    

        Tenant
designates the person named from time to time as Tenant's Authorized Representative to take all acts of Tenant hereunder. Landlord may rely on the acts of such Authorized
Representative without further inquiry or evidence of authority. Tenant's Authorized Representative shall be the person so designated in Section 1.1 and such successors as may be named from
time to time by the then current Tenant's Authorized Representative or by Tenant's president. 

        8.15    NOTICE OF LEASE    

        Landlord
and Tenant agree not to record this Lease. If appropriate, both parties will, within ten (10) days after the request of either, execute, acknowledge and deliver a Notice
of Lease and a Notice of Termination of Lease Term, each in recordable form. Such notices shall contain only the information required by law for recording. 

        8.16    TENANT AS BUSINESS ENTITY    

        If
Tenant is a business entity, then the person or persons executing this Lease on behalf of Tenant jointly and severally warrant and represent in their individual capacities that
(a) Tenant is duly organized, validly existing and in good standing under the laws of the jurisdiction in which such entity was organized; (b) Tenant has the authority to own its
property and to carry on its business as contemplated under this Lease; (c) Tenant is in material compliance with all laws and orders of public authorities applicable to Tenant;
(d) Tenant has duly executed and delivered this lease; (e) the execution, delivery and performance by Tenant of this Lease (i) are within the powers of Tenant, (ii) have
been duly authorized by all requisite action, (iii) will not violate any provision of law or any 

18

 

order
of any court or agency of government, or any agreement or other instrument to which Tenant is a party or by which it or any of its property is bound, and (iv) will not result in the
imposition of any lien or charge on any of Tenant's property, except by the provisions of this Lease; and (v) the Lease is a valid and binding obligation of Tenant in accordance with its terms.
Tenant, if a business entity, agrees that breach of the foregoing warranty and representation shall at Landlord's election be a default under this Lease for which there shall be no cure. This warranty
and representation shall survive the termination of the Term. 

        8.17    RELOCATION    Intentionally omitted 

        8.18    LETTER OF CREDIT SECURITY DEPOSIT    

        Within
ten (10) business days after the date of this Lease but in any event prior to occupancy of any portion of the Premises, Tenant shall pay to Landlord as a security deposit
for the performance of the obligations of Tenant hereunder the amount of $3,000,000.00 (the "Initial Letter of Credit Security Deposit") in the form of a letter of credit in accordance with the
provisions of this Section 8.18. 

        (a)   Tenant
shall deliver to Landlord the Initial Letter of Credit Security Deposit containing all of the following terms and satisfying all of the following conditions
(which terms and conditions are hereinafter referred to as the "Letter of Credit Terms and Conditions"): (i) the letter of credit shall be irrevocable, (ii) the letter of credit shall
only require the 

        (f)    Tenant
shall have the right to convert the Letter of Credit Security Deposit into a cash security deposit. Said cash security deposit may be mingled with other funds of
Landlord and no fiduciary relationship shall be created with respect to such deposit. If Tenant shall default (including applicable notice and cure periods), Landlord may, but shall not be obliged to,
apply the cash security deposit to the extent necessary to cure the default, and Tenant shall be obliged to reinstate such cash security deposit to the then currently-required amount (as reduced
according to the applicable schedule in (e) above) thereof upon written demand. Upon a reduction of the cash security deposit upon the terms and conditions in (e) above, Landlord shall
pay Tenant, the amount of such reduction within thirty (30) days. Within thirty (30) days after the expiration or sooner termination of the Term, the cash security deposit or the letter
of credit security deposit, as the case may be, to the extent not applied, shall be returned to the Tenant, without interest. 

        8.19    MISCELLANEOUS PROVISIONS    

        This
Lease may be executed in counterparts and shall constitute the agreement of Landlord and Tenant whether or not their signatures appear in a single copy hereof. This Lease shall be
construed as a sealed instrument and shall be governed exclusively by the provisions hereof and by the laws of The Commonwealth of Massachusetts as the same may from time to time exist. The titles are
for convenience only and shall not be considered a part of the Lease. Where the phrases "persons acting under Tenant" or "persons claiming under Tenant" or similar phrases are used, the persons
included shall be all employees, agents, independent contractors and invitees of Tenant or of any Transferee of Tenant. The enumeration of specific examples of or inclusions in a general provision
shall not be construed as a limitation of the general provision. If Tenant is granted any extension option, expansion option or other right or option, the exercise of such right or option (and notice
thereof) must be unconditional to be effective, time always being of the essence to the exercise of such right or option; and if Tenant purports to condition the exercise of any option or to vary its
terms in any manner, then the option granted shall be void and the purported exercise shall be ineffective. Unless otherwise stated herein, any consent or approval required hereunder may be given or
withheld in the sole absolute discretion of the party whose consent or approval is required. Nothing herein shall be construed as creating the relationship between Landlord and Tenant of principal and
agent, or of partners or joint venturers or any relationship other than landlord and tenant. This Lease and all consents, notices, approvals and all other documents relating hereto may be reproduced
by any party by photographic, 

19

 

microfilm,
microfiche or other reproduction process and the originals thereof may be destroyed; and each party agrees that any reproductions shall be admissible in evidence as the original itself in
any judicial or administrative proceeding (whether or not the original is in existence and whether or not reproduction was made in the regular course of business) and that any further reproduction of
such reproduction shall likewise be admissible in evidence. This Lease may be amended only by a writing signed by all of the parties hereto. 

        8.20    SIGNAGE AND BUILDING NAME    

        Tenant
shall have the right to install its logo on the monument sign of the Building, to be listed with the other tenants of the Building, at its sole cost and expense. At Tenant's
initial occupancy, Landlord shall provide Tenant with standard building directory and lobby signage. Tenant shall have the non-exclusive right to install additional interior signage in the
Building consistent with the signage permitted other office tenants of the Building. All signage shall be subject to the prior written approval of Landlord, such approval not to be unreasonably
withheld or delayed, and in compliance with all governmental laws. 

 
 

ARTICLE IX    
    
    LANDLORD'S LIABILITY AND ASSIGNMENT FOR FINANCING    
    

        9.1    LANDLORD'S LIABILITY    

        Tenant
agrees from time to time to look only to Landlord's interest in the Land and Building for satisfaction of any claim against Landlord hereunder or under any other instrument
related to the Lease (including any separate agreements among the parties and any notices or certificates delivered by Landlord) and not to any other property or assets of Landlord. If Landlord from
time to time transfers its interest in the Land and Building (or part thereof which includes the Premises), then from and after each such transfer Tenant shall look solely to the interests in the Land
and Building of each of Landlord's transferees for the performance of all of the obligations of Landlord hereunder (or under any related instrument). The obligations of Landlord shall not be binding
on any partners (or trustees or beneficiaries) of Landlord or of any successor, individually, but only upon Landlord's or such successor's interest described above. 

        In
no event shall Landlord ever be liable for any indirect or consequential damages. 

        9.2    ASSIGNMENT OF RENTS    

        If,
at any time and from time to time, Landlord assigns this Lease or the rents payable hereunder to the holder of any mortgage on the Building, or to any other party for the purpose of
securing financing (the holder of any such mortgage and any other such financing party are referred to herein as the "Financing Party"), whether such assignment is conditional in nature or otherwise,
the following provisions shall apply: 

          (i)  Such
assignment to the Financing Party shall not be deemed an assumption by the Financing Party of any obligations of Landlord hereunder unless such Financing Party
shall, by written notice to Tenant, specifically otherwise elect; 

         (ii)  Except
as provided in (i) above and (iii) below, the Financing Party shall be treated as having assumed Landlord's obligations hereunder (subject to
Section 9.1) only upon foreclosure of its mortgage (or voluntary conveyance by deed in lieu thereof) and the taking of possession of the Premises from and after foreclosure and, with respect to
obligations regarding return of the security deposit, only upon receipt of the funds constituting such security deposit; 

        (iii)  Subject
to Section 9.1, the Financing Party shall be responsible for only such breaches under the Lease by Landlord which occur during the period of ownership
by the Financing Party 

20

 

after
such foreclosure (or voluntary conveyance by deed in lieu thereof) and taking of possession, and defaults which are continuing as of such date, as aforesaid; 

        (iv)  In
the event Tenant alleges that Landlord is in default under any of Landlord's obligations under this Lease, Tenant agrees to give the holder of any mortgage, by
registered mail, a copy of any notice of default which is served upon the Landlord, provided that prior to such notice, Tenant has been notified, in writing, (whether by way of notice of an assignment
of lease, request to execute an estoppel letter, or otherwise) of the address of any such holder. Tenant further agrees that if Landlord shall have failed to cure such default within the time provided
by law or such additional time as may be provided in such notice to Landlord, such holder shall have sixty (60) days after the last date on which Landlord could have cured such default within
which such holder will be permitted to cure such default. If such default cannot be cured within such sixty-day period, then such holder shall have such additional time as may be necessary
to cure such default, if within such sixty day period such holder has commenced and is diligently pursuing the remedies necessary to effect such cure (including, but not limited to, commencement of
foreclosure proceedings, if necessary, to effect such cure), in which event Tenant shall have no right with respect to such default while such remedies are being diligently pursued by such holder. 

        In
all events, any liability of a Financing Party shall be limited to the interest of such Financing Party in the Land and Building, and in no event shall a Financing Party ever be
liable for any indirect or consequential damages. 

        Tenant
hereby agrees to enter into such agreements or instruments as may, from time to time, be reasonably requested in confirmation of the foregoing. 

        Without
limiting the generality of the foregoing, Tenant acknowledges that Landlord's interest in this Lease has been assigned to Principal Mutual Life Insurance Company ("Principal")
pursuant to an Assignment of Leases and Rents dated November 25, 1996 ("Lease Assignment") and recorded with the Middlesex South Registry of Deeds as Instrument Number 737 on
November 25, 1996. Until the Lease Assignment is discharged of record, Tenant shall, upon notice by Principal, make payments under this Lease as directed by Principal. Unless and until such
notice is given by Principal, all payments shall be made as set forth in Section 2.5. 

 
 

ARTICLE X    
    
    SUBORDINATION AND NON-DISTURBANCE    
    

        This Lease shall be subject and subordinate to any first mortgage and to any junior mortgage that has been approved by the first mortgagee that may now be placed
upon the Building and/or the Land and to any and all advances to be made under such mortgages and to the interest thereon, and all renewals, extensions and consolidations thereof. Any mortgagee may
elect to give this Lease priority to its mortgage, except that the Lease shall not have priority to (i) the prior right, claim and lien of such mortgagees in, to and upon any insurance proceeds
and the disposition thereof under the mortgage; (ii) the prior right, claim and lien of such mortgagees in, to and upon any award or compensation heretofore or hereafter to be made for any
taking by eminent domain of any part of the Premises, and to the right of disposition thereof under the mortgage; and (iii) any lien, right, power or interest, if any, which may have arisen or
intervened in the period between the recording of the mortgages and the execution of this Lease, or any lien or judgment which may arise any time under the terms of this Lease. In the event of such
election and upon notification by such mortgagee, this Lease shall be deemed prior in lien to the said mortgage. This Section shall be self-operative, but in confirmation thereof, Tenant
shall execute and deliver a Non-disturbance, and Attornment Agreement (an "SNDA") substantially in the form attached hereto as Exhibit F. With respect to any future mortgagee,
Tenant shall agree to subordinate this Lease upon the execution of an SNDA reasonably mutually agreeable to the parties, in recordable form, and containing substantially the same terms and provisions
as those set 

21

 

forth
in Exhibit J hereto. Landlord shall use diligent efforts to obtain a non-disturbance agreement from its current mortgagee prior to Tenant's occupancy of the Premises, and all
future mortgagees and ground lessors, if any. 

 
 

ARTICLE XI    
    
    PARKING    
    

        11.1    GENERAL    

        Landlord
agrees to provide an automobile parking area during the term of this Lease for the benefit and use of the customers and employees of Tenant, and other tenants and occupants of
the Building. Tenant shall have the right to use, in common with others, parking spaces on a non-exclusive basis in the automobile parking area throughout the Term of this Lease. Wherever
the words "automobile parking area" are used in this Lease, it is intended that the same shall include, whether in a surface parking area or a parking structure, the automobile parking stalls,
driveways, entrances, exits, sidewalks, landscaped areas, pedestrian passageways in conjunction (herewith and other areas designated for parking. Landlord shall keep the automobile parking area neat,
clean and in good repair, properly lighted, paved and landscaped and Landlord shall be responsible for plowing and removing snow and ice in the automobile parking area. Nothing contained herein shall
be deemed to create liability upon Landlord for any damage to motor vehicles of customers or employees or from loss of property from within such motor vehicles, unless caused by the negligence of
Landlord, its agents, servants and employees. Landlord shall have the right to establish and enforce against all users of the automobile parking area, such reasonable rules and regulations as may be
deemed necessary and advisable for the proper and efficient operation and maintenance of the automobile parking area, including the hours during which the automobile parking area shall be open for
use. 

        Landlord
may establish for the automobile parking area, a system or systems of charged validation or other operation including, but not limited to, a system of charges against
nonvalidated parking checks of users. Tenant shall comply with such system, and all rules and regulations established by Landlord in conjunction with such system, and shall cause its customers and
employees to comply therewith; provided, however, that such system and such rules and regulations shall apply equally and without discrimination to all persons entitled to the use of the automobile
parking area, and provided that at all times Tenant and its agents, servants, employees, licensees, invitees and guests shall be entitled to park in the automobile parking area free of any charge or
fee. 

        Landlord
shall at all times during the term hereof have the sole and exclusive control of the automobile parking area, and may at any time during the term hereof exclude and restrain any
person from use thereof; excepting, however, Tenant and its employees, bona fide customers, patrons and service suppliers of Tenant and other tenants of Landlord who make use of said area in
accordance with any non-discriminatory rules and regulations established by Landlord from time to time with respect thereto. Landlord shall also have the right to designate certain
automobile parking
areas as being for the exclusive use of one or more of the Tenants of Landlord, provided, however, that Landlord shall not offer on an exclusive basis any parking spaces immediately adjacent to the
Building. The rights of Tenant referred to in this Article shall at all times be subject to the rights of Landlord and the other tenants of Landlord to use the same in common with Tenant, and it shall
be the duty of Tenant to keep all of said area free and clear of any obstructions created or permitted by Tenant or resulting from Tenant's operations and to permit the use of any of said area only
for normal parking and ingress and egress by said customers, patrons and service suppliers to and from the Building. 

        Landlord
shall at all times have the right and privilege of determining the nature and extent of the automobile parking area, whether the same shall be surface, underground or other
structure, and of making such changes therein from time to time which in its opinion are deemed to be desirable and for the best interests of all persons using the automobile parking area. 

22

 

        11.2    EMPLOYEE PARKING    

        It
is understood and agreed that the employees of Tenant and the other tenants of Landlord within the Building shall not be permitted to park their automobiles in the portions of the
automobile parking area which may from time to time be designated for patrons of the Building and that Landlord shall at all times have the right to establish nondiscriminatory rules and regulations
for employee parking. 

        11.3    PATRON PARKING    

        Landlord
agrees to provide within the automobile parking area parking spaces for the patrons of Tenant and other tenants in the Building in sufficient number as from time to time
Landlord shall deem appropriate. 

        11.4    OTHER PARKING USERS    

        Landlord
may authorize persons other than those described above, including occupants of other buildings, to utilize said automobile parking area.

Dr. Pieter
Muntendam 642

Main Street

Boxford, MA 01921 

Dear
Pieter: 

        On
behalf of BG Medicine, Inc. (the "Company"), and the entire Board of Directors of the Company, I am delighted to offer you the position of President and
Chief Operating Officer, initially reporting to Noubar B. Afeyan, Ph.D., the Chairman and Chief Executive Officer of the Company. We anticipate that your employment will start
effective December 13, 2004 (the "Start Date"). In this key position you will be appointed as a member of the Company's Board of Directors and will have responsibility for the strategic
direction and operating performance of the Company. You will also perform such other and/or different services for the Company as may be assigned to you from time to time by the Chairman and Chief
Executive Officer. 

        This
letter and the accompanying documents and agreements summarize and set forth important terms about your employment with the Company. As is generally true for Company employees, you
will be employed on an at-will basis, which means that neither you nor the Company are guaranteeing this employment relationship for any specific period of time. Either of us may choose to
end the employment relationship at any time, for any reason. In addition, you should understand that the descriptions of benefits and other compensation arrangements set forth herein are meant to be
summary in form and may be subject to change. If any benefit is subject to a benefit plan, the terms of that plan will control. The Company reserves the right to alter, supplement or rescind its
employment procedures, benefits or policies (other than the employment at-will policy) at any time in its sole and absolute discretion and without notice. 

        1.    Compensation.    

        a.    Salary.    Initially, your salary will be in the gross
semi-monthly amount of $9,791.67 (which is equivalent to an annual rate of $235,000). 

        c.    Annual Performance Bonus.    You will also be eligible to
receive an annual bonus of up to fifty percent (50%) of your base salary, payable upon the achievement as determined by the Board of Directors of specific milestones to be mutually agreed upon by you
and the Board. 

        d.    Stock Options.    Promptly following the Start Date, subject to
the terms of and contingent upon your execution of an incentive stock option agreement (the "ISO Agreement") issued pursuant to the Company's 2001 Stock Option and Incentive Plan, as amended, and
subject to Board approval, you will be granted an option to purchase 650,000 shares of common stock of the Company at an exercise price equal to the fair market value of the stock at the time of the
grant as determined by the Board of Directors. This option will vest 25% on the first anniversary of your Start Date and thereafter the remaining 75% shall vest on a quarterly basis on the last day of
each quarter over a period of three years, provided that you remain employed on the vesting day. Additionally, upon a "change of control" (as defined in the ISO Agreement) of the Company during your
employment by the Company, 50% of your unvested options, at the time of such change of control, will immediately vest. 

1

 

        e.    Benefits.    You will be eligible to participate in the
Company's benefit plans to the same extent as, and subject to the same terms, conditions and limitations applicable to, other Company employees of similar rank and tenure. Summaries of each of the
Company's benefit plans are available to you. In addition, you will be reimbursed for all reasonable out-of-pocket expenses incurred during the performance of your duties, in
accordance with the Company's reimbursement policies as established or modified from time to time by the Company. Each calendar year you will be eligible to accrue up to four (4) weeks vacation
and up to twelve (12) holidays (initial employment year will be pro-rated), as set forth by the Company, 

        2.    Working Commitment.    While you are employed by the Company,
you will use your best efforts, skills and abilities to perform faithfully all duties assigned to you in your role as an employee of the Company and will devote your full business time and energies to
the business and affairs of the Company. 

        3.    Severance Pay and Benefits Upon Termination Of Employment.    As
explained, you will be employed as an at-will employee. Should the Company terminate your employment without Cause (as defined in the ISO Agreement), and conditioned upon your execution of
a separation agreement which contains, among other things, a general release of claims, you will receive severance pay equivalent to six months of your annual base salary at the time of such
termination. In addition, if during your first two years of employment, as a result of the hiring of a new Chief Executive Officer your employment with the Company is terminated without Cause, your
unvested options will be subject to accelerated vesting such that 50% of your initial equity grant with the Company shall immediately vest on the effective date of the termination of your termination.
The Company shall have no obligation to make or continue any payment pursuant to this offer letter unless you have signed a release agreement in a form satisfactory to the Company. 

        4.    Certifications by You.    By signing this Offer letter, you are
certifying to the Company that (i) your employment with the Company does not, and will not, require you to breach any agreement entered into by you prior to employment with the Company (i.e.,
you have not entered into any agreements with previous employers that are in conflict with your obligations to the Company); and (ii) to the extent you are subject to restrictive agreements
with any prior employer that may affect your employment with the Company, you have provided us with a copy of that agreement. Please understand that the Company does not want you to disclose any
confidential information belonging to a previous employer or to incorporate the proprietary information of any previous employer into the Company's proprietary information and expects that you will
abide by restrictive covenants to prior employers. 

        5.    Required 1-9 Documentation.    For purposes of
completing the INS 1-9 form, you must provide us sufficient documentation to demonstrate your eligibility to work in the United States on or before your first day of employment. If you
have any questions about what documentation you must provide, please contact Stacie Rader, our Vice President, Human Resources.
