PREMISES,
TERM AND COMMENCEMENT OF TERM

 

2.1         Premises.
Landlord hereby leases to Tenant the Premises subject to and with the benefit of the terms, covenants, conditions and provisions
of this Lease and all easements, covenants and restrictions appurtenant thereto, if any. Tenant shall have the use, in common
with others entitled thereto, of the roadways, driveways, parking areas, sidewalks and all other common areas serving the Building,
all subject to reasonable rules and regulations promulgated by Landlord from time to time.

 

In
addition, Tenant shall have the exclusive right to use up to eighty (80) parking spaces in the parking area serving the Building,
as shown on Exhibit B attached hereto.

 

2.2         Term. TO HAVE AND TO HOLD the Premises
for the Lease Term, commencing on the Term Commencement Date, subject to the terms, covenants, agreements and conditions contained
in this Lease. Notwithstanding the foregoing, Landlord acknowledges and agrees that, commencing thirty (30) days prior to the
Term Commencement Date (the “Early Access Date”), Tenant shall have access to the Premises for the purpose
of installing fixtures, furniture, telephones and other equipment at the Premises; provided, however, that any such entry onto
the Premises prior to the Term Commencement Date shall be subject to all of the terms and provisions of this Lease (except for
Tenant’s obligation to pay Rent, which shall not be payable until the Rent Commencement Date); and further provided that
Tenant shall not in any way interfere with the performance of Landlord’s Work (as defined herein) during such period of
early access.

 

2.3         Condominium. Tenant hereby acknowledges
that Landlord may determine to establish a condominium in which the Premises will be located. If Landlord determines to establish
a condominium, then this Lease shall be subject and subordinate to all of the documents creating the condominium, provided that
such documents shall be reasonable, shall not (i) adversely affect Tenant’s permitted use; (ii) decrease Tenant’s
rights; and/or (iii) increase Tenant’s obligations hereunder, excepting any increase of Real Estate Taxes as a result of
establishment of the condominium. To the extent that under the condominium documents it is the obligation of the condominium and
not of the unit owner to maintain any portion of the Building or the Site, to provide restoration in case of fire, casualty or
taking or to provide any insurance for, or services to, the Building or the Site, then notwithstanding anything in this Lease
to the contrary, Landlord’s sole obligation with respect thereto shall be to enforce its rights under the condominium documents
to obligate the condominium to provide such insurance or services or to perform such maintenance or restoration.

month included at the beginning or end of the Lease Term, 1/30 of a monthly payment being due for each day of a partial month,
payable on the first day of such month or partial month. During the period between the Term Commencement Date and the Rent Commencement
Date, Tenant shall be responsible for payments of Additional Rent as set forth in Section 3.3 below.

 

3.2         Additional
Rent – Real Estate Taxes. In addition to the Base Rent, during the Lease Term, Tenant shall also pay to Landlord, as
Additional Rent, Tenant’s Proportionate Share of all Real Estate Taxes in excess of Base Year Real Estate Taxes (“Tenant’s
Tax Obligation”) as provided in this Section 3.2.

 

(a)          For the purposes of this Section 3.2,
the following words and terms shall have the following meaning:

 

(i)          “Real
Estate Taxes” shall mean all taxes including real estate taxes (which term shall include payments in lieu of real estate
taxes), assessments, levies, license and permit fees and other governmental charges, general and special, ordinary and extraordinary,
foreseen and unforeseen, of any kind and nature whatsoever, which at any time during the Lease Term may be assessed, levied, confirmed,
imposed upon, or may become due and payable out of or in respect of, or become a lien upon, all or any portion of the Site (including,
without limitation, all improvements thereto) other than: (A) municipal, state and federal income taxes (if any) assessed against
Landlord; or (B) municipal, state or federal capital levy, gift, estate, succession, inheritance or transfer taxes of Landlord;
or (C) corporation excess profits or franchise taxes imposed upon any corporate owner of the Site, provided, however, that if
at any time during the Lease Term the methods of taxation prevailing at the commencement of the Lease Term shall be altered so
that in lieu of, as a substitute for, or in addition to, the whole or any part of the taxes, assessments, levies or charges now
levied, assessed or imposed on real estate and the improvements thereon (other than as specifically excepted in (A), (B) or (C)
above), there shall be levied, assessed and imposed a tax, assessment, levy, imposition or charge, wholly or partially as
a capital levy or otherwise, on the rents received therefrom, or measured by or based in whole or in part upon the Site and imposed
upon Landlord, then all such taxes, assessments, levies, impositions or charges or the part thereof so measured or based, shall
be deemed to be included within the term “Real Estate Taxes” for the purposes hereof. In addition to the foregoing,
the term “Real Estate Taxes” shall include any new tax of a nature not presently in effect, but which may be hereafter
levied, assessed, or imposed upon Landlord or all or any portion of the Site, if such tax shall be based on or arise out of the
ownership, use or occupation of all or any portion of the Site.

EXECUTION VERSION

 

(ii)          “Tax Year” shall mean the
twelve-month period commencing July 1st, and each twelve-month period commencing on an anniversary of said date during the Lease
Term.

 

(iii)         “Tax Statement” shall mean
a statement setting forth in reasonable detail the amount payable by Tenant with respect to Real Estate Taxes for any Tax Year.

 

(b)          Landlord
shall bill Tenant monthly, on an estimated basis, for Tenant’s Tax Obligation. Within one hundred twenty (120) days after
the close of each Tax Year during the Lease Term, Landlord shall render an annual bill (i.e., a Tax Statement) for such Tax Year,
which annual bill shall make appropriate adjustment as may be necessary to reflect Tenant’s Tax Obligation based on the
actual Real Estate Taxes during such Tax Year, including, without limitation, any refund that may be due to Tenant, to be taken
as a credit against future payments of Additional Rent due hereunder.

 

(c)          Any
bills for Tenant’s Tax Obligation shall be due at the same time and in the same manner as the next monthly installment of
Base Rent is due pursuant to Section 3.1, or if the Lease Term has terminated or expired, within ten (10) days after receipt
of such bill.

 

(d)          Appropriate credit against any Tenant’s
Tax Obligation shall be given for any refund obtained by reason of a reduction in any Real Estate Taxes by the courts or other
governmental agency responsible therefor. The original computation of Tenant’s Tax Obligation, as well as reimbursement
or payments of additional charges, if any, or allowances, if any, under the provisions of this Section 3.2 shall be based
on the original assessed valuations, with adjustments to be made at a later date when the tax refund, if any, shall be paid to
Landlord by the taxing authority. Expenditures for legal fees and for other similar or dissimilar expenses incurred in obtaining
the tax refund shall be charged against the tax refund before the adjustments are made for any Tax Year. In no event shall Tenant
be entitled to receive a credit against Tenant’s Tax Obligation for any Tax Year in an amount greater than Tenant’s
Tax Obligation for such Tax Year.

 

(e)           If the Term Commencement Date or the expiration
or earlier termination of the Lease Term occurs in the middle of a Tax Year, Tenant shall be liable for only that portion of Tenant’s
Tax Obligation in respect of said Tax Year represented by a fraction, the numerator of which is the number of days of the herein
Lease Term which falls within said Tax Year, and the denominator of which is three hundred sixty-five (365).

    6

     

    

EXECUTION VERSION

 

(f)         In
the event the first day of the Tax Year in the City of Watertown should be changed after the Term Commencement Date to a day other
than July 1 so as to change the twelve (12) month period comprising a Tax Year, in determining Tenant’s Tax Obligation with
respect to Real Estate Taxes payable for the period between July 1 and such changed first day of the Tax Year, Tenant’s
Tax Obligation shall be multiplied by a fraction, the numerator of which shall be the number of days elapsing during such period,
and the denominator of which shall be three hundred sixty-five (365).

 

(g)        Any obligation of Tenant under this Section
3.2 which shall not have been paid at the expiration of the Lease Term shall survive such expiration and shall be paid when
and as the amount of same shall be determined to be due.

 

3.3         Additional
Rent – Operating Expenses. In addition to the Base Rent, during the Lease Term, Tenant shall also pay to Landlord, as
Additional Rent, Tenant’s Proportionate Share of all Operating Expenses in excess of Base Year Operating Expenses (“Tenant’s
Operating Expense Obligation”), as provided in this Section 3.3.

 

(a)         For the purposes of this Section 3.3,
the following words and terms shall have the following meaning:

 

(i)           “Operating
Expenses” shall mean the aggregate expenses incurred by Landlord in the operation, maintenance and management of the
Site (including, without limitation, the Building, parking areas and other improvements thereon) during the Lease Term including,
without limitation, the following: (A) utilities supplied to the Site (to the extent the same are not being paid directly by Tenant);
(B) compensation and “fringe” benefits for employees below the grade of Director of Property Management or contractors
engaged on a full-time basis in connection with servicing the Site and payroll taxes, workmen’s compensation insurance premiums
and similar costs with respect thereto, and an appropriate portion of same with respect to employees or contractors on a part-time
basis; (C) all insurance obtained by Landlord relating to or otherwise in connection with its ownership or the operation, rental,
or management of the Site, the foregoing to include without limitation any liability insurance, rent loss insurance, and any other
insurance required by Landlord’s Mortgagee; (D) services obtained for the benefit of the Site (including, without limitation,
snow removal and grounds maintenance); (E) repairs, replacement, repainting, maintenance, supplies and the like for the Site;
(F) management fees equal to three percent (3%) of gross rentals from the Building per annum; (G) legal fees and expenses, and
any consulting fees and expenses in connection with any reduction of any Operating Expenses or Real Estate Taxes; (H) auditing
fees and expenses; (I) to the extent that any of such Operating Expenses are required to be capitalized under federal income
tax law, the same shall be amortized over their useful life in accordance with generally accepted accounting principles, and the
amortized portion thereof, for the period falling within the Lease Term, together with reasonable interest, shall be included
in “Operating Expenses;” and (J) the fair and equitable allocable portion to the Building and/or the Site (as reasonably
determined by Landlord, using commercially reasonable methods of calculation) of any costs and expenses related to the maintenance,
repair, replacement, restoration, alteration, paving, re-paving, patching, snowplowing, de-icing, sanding, policing, lighting
and landscaping of the common driveways and other common areas on the Site (the “Site Expenses”). The method
currently used by Landlord for allocating Site Expenses, which the parties agree is commercially reasonable, is to allocate
the costs for services provided for the benefit of either all or a portion of the buildings at the Site (the “Benefited
Buildings”) to only the Benefited Buildings, on a pro rata basis where the numerator is the size of the building and
the denominator is the size of all the Benefited Buildings. The Site Expenses shall not duplicate any items in the Building Operating
Expenses, and shall not include any expenses for services provided exclusively to and paid for exclusively by any building on
the Site.

    7

     

    

EXECUTION VERSION

 

The
following items shall be excluded from “Operating Expenses” except as specifically provided above: (A) principal or
interest payments on any mortgages or other financing arrangements, (B) leasing commissions, (C) depreciation for the Site; (D)
capital expenditures, as defined under generally accepted accounting principles (other than the portion to be included in Operating
Expenses as described in subsection (I) above); (E) ground rent under ground leases; (F) utility charges payable by Tenant directly
to the applicable provider, (G) any costs, fines or penalties incurred due to violations by Landlord of any Legal Requirements
provided that such violation is not caused, directly or indirectly, by any act or omission of Tenant or any employee, agent, contractor,
subcontractor, customer or business invitee of Tenant; (H) costs covered by a guarantee or warranty; and (I) marketing costs.

 

(ii)          “Computation Year” shall mean
each calendar year beginning with calendar year 2018.

 

(iii)         “Operating Expense Statement”
shall mean a statement setting forth in reasonable detail the amount payable by Tenant with respect to Operating Expenses for
any Computation Year.

 

(b)          Landlord
shall bill Tenant monthly, on an estimated basis, for Tenant’s Operating Expense Obligation. Any estimated bill need not
include all of the items mentioned in Section 3.3(a)(i). Within one hundred twenty (120) days after the close of each Computation
Year during the Lease Term, Landlord shall render an annual bill for such year which annual bill shall make all adjustments as
may be necessary to reflect actual changes during that year including, without limitation, any refund that may be due to Tenant,
to be taken as a credit against future payments of Additional Rent due hereunder. All bills for Tenant’s Operating Expense
Obligation shall be due at the same time and in the same manner as the next monthly installment of Base Rent is due pursuant to
Section 3.1, or if the Lease Term has terminated or expired, within ten (10) days of receipt of such bill.

 

(c)           If the Term Commencement Date or the expiration
or earlier termination of the Lease Term occurs in the middle of a Computation Year, Tenant shall be liable for only that portion
of Tenant’s Operating Expense Obligation in respect of such Computation Year represented by a fraction, the numerator of
which is the number of days of the herein term which falls within the Computation Year, and the denominator of which is three
hundred sixty-five (365).

 

(d)           Any obligation of Tenant under this Section
3.3 which shall not have been paid at the expiration of the Lease Term shall survive such expiration and shall be paid when
and as the amount of same shall be determined to be due.

    8

     

    

EXECUTION VERSION

 

(e)           If (i) occupancy during any Computation Year
is less than one hundred percent (100%), and/or (ii) any utilities for any occupied space in the Building are directly billed
to the occupant thereof, then Operating Expenses for such Computation Year shall be “grossed up” to that amount of
Operating Expenses that, using reasonable projections, would normally be expected to be incurred during such Computation Year
if the Building were one hundred percent (100%) occupied during such Computation Year, and/or the utilities in question had not
been directly billed for such period, as determined under generally accepted accounting principles consistently applied. Only
those components of Operating Expenses that are affected by variations in occupancy levels shall be “grossed up” in
accordance herewith. In addition, in the event that, during any Computation Year, any component of Operating Expenses included
in Operating Expenses for the Base Year is no longer incurred by Landlord, then for purposes of determining Tenant’s Operating
Expense Obligation on and after such discontinuance, Operating Expenses for the Base Year shall be recalculated to subtract the
amount of such component.

 

3.4         Rent.
References in this Lease to “Rent” or “rent” shall be deemed to include both Base Rent and Additional
Rent when the context so allows. All monetary obligations of Tenant under this Lease, except for the obligation to pay Base Rent,
shall be deemed obligations to pay Additional Rent, unless such presumption is repugnant to the context.

 

3.5        
Independent Covenants. Each covenant,
agreement, obligation and/or other provision in this Lease to be performed on Tenant’s part shall be deemed and construed
to be a separate and independent covenant of Tenant and not dependent on any other provision of this Lease. Tenant acknowledges
and agrees that its covenant to pay Base Rent, Additional Rent and other sums payable under this Lease, and to observe, perform
and comply with any other obligations of Tenant under this Lease, is independent of Landlord’s obligations under this Lease,
and that in the event that Tenant shall have a claim against Landlord, Tenant shall not have the right to deduct the amount allegedly
owed to Tenant from any Base Rent, Additional Rent or other sums payable under this Lease, it being understood that Tenant’s
sole remedy for recovering upon such claim shall be to bring an independent legal action against Landlord.

SECURITY DEPOSIT

 

4.1         Security
Deposit. Upon the execution and delivery of this Lease, Tenant shall deliver to Landlord a security deposit in the amount
of Three Hundred Thirty-Six Thousand and 00/100 Dollars ($336,000.00) (the “Security Deposit”). Landlord shall
hold the same throughout the Lease Term as security for the performance by Tenant of all obligations on the part of Tenant hereunder.
Landlord shall have the right from time to time, without prejudice to any other remedy Landlord may have on account thereof, to
apply such Security Deposit, or any part thereof, to Landlord’s damages arising from, or to cure, any default by Tenant
of its obligations hereunder beyond the expiration of any applicable grace periods. If Landlord shall so apply any or all of such
Security Deposit, Tenant shall immediately upon demand deposit with Landlord the amount so applied to be held as security hereunder.
Landlord shall return the Security Deposit, or so much thereof as shall have theretofore not been applied in accordance with the
terms of this Section 4.1, to Tenant on the expiration or earlier termination of the Lease Term and the surrender of possession
of the Premises by Tenant to Landlord at such time, provided that there is then existing no default of Tenant (nor any circumstance
which, with the passage of time or the giving of notice, or both, would constitute a default of Tenant). While Landlord holds
such Security Deposit, Landlord shall have no obligation to pay interest on the same and shall have the right to commingle the
same with Landlord’s other funds. If Landlord conveys Landlord’s interest under this Lease, the Security Deposit,
or any part thereof not previously applied, shall be turned over by Landlord to Landlord’s grantee, and, if so turned over,
Tenant agrees to look solely to such grantee for proper application of the Security Deposit in accordance with the terms of this
Section 4.1, and the return thereof in accordance herewith. Landlord’s Mortgagee shall not be responsible to Tenant
for the return or application of any such Security Deposit, whether or not it succeeds to the position of Landlord hereunder,
unless such deposit shall have been received in hand by such Mortgagee.

    9

     

    

EXECUTION VERSION

 

4.2         Reduction of Security Deposit. Notwithstanding
any other provision of this Article 4, the Security Deposit shall automatically be reduced in accordance with the following schedule
(the “Reduction”) provided that no monetary Event of Default has occurred hereunder prior to the date of such
Reduction:

 

	Date of Reduction	 	Amount of Reduction	 	 	Remaining Balance	 
	First anniversary of the Rent Commencement Date	 	$	168,000.00	 	 	$	168,000.00	 
	Second anniversary of the Rent Commencement Date	 	$	84,000.00	 	 	$	84,000.00	 

 

The
Reduction set forth above shall automatically be applied to the next monthly installment of Base Rent then due and payable under
this Lease. In the event that the Security Deposit is provided via a Letter of Credit pursuant to Section 4.3 below, and
Tenant is entitled to the Reduction, Landlord agrees to return the existing Letter of Credit upon the availability of a replacement
Letter of Credit (each, a “Replacement Letter of Credit”) satisfying the requirements of Section 4.3
below, such Replacement Letter of Credit to be in the amount of the applicable Remaining Balance set forth above.

 

4.3         Letter
of Credit. At Tenant’s option, Tenant’s obligation to provide the Security Deposit in accordance with this Article 4
may be satisfied by Tenant delivering to Landlord, simultaneously with the execution of this Lease, an Irrevocable Standby Letter of
Credit (the “Original Letter of Credit”) which shall be (1) in the form attached hereto as Exhibit E; (2) issued
by a bank reasonably acceptable to Landlord upon which presentation may be made in Boston, Massachusetts; (3) in the amount of Three
Hundred Thirty-Six Thousand and 00/100 Dollars ($336,000.00); and (4) for a term of one (1) year, subject to the provisions of this Section
4.2. The Original Letter of Credit and any Replacement Letter(s) of Credit, Substitute Letter(s) of Credit and Additional Letter(s)
of Credit (as such terms are defined hereinbelow) are referred to herein collectively and respectively as the “Letter of Credit.”

 

              The
Letter of Credit shall be automatically renewable in accordance with terms of Exhibit E; provided, however, that Tenant
shall be required to deliver to Landlord a new letter of credit satisfying the conditions set forth in this Section 4.2

EXECUTION VERSION

 

In
the event that Tenant is in default, beyond the expiration of any applicable grace periods, of its obligations under this Lease,
then Landlord shall have the right, at any time after such event to (1) draw down from said Letter of Credit the amount necessary
to cure such default; or (2) if such default cannot reasonably be cured by the expenditure of money, to exercise all rights and
remedies Landlord may have on account of such default and to draw down from said Letter of Credit the amount which is necessary
to satisfy Tenant’s liability on account thereof. In the event of any such draw by Landlord, Tenant shall, within fifteen
(15) business days of written demand therefor, deliver to Landlord an additional Letter of Credit satisfying the foregoing conditions
(the “Additional Letter of Credit”), except that the amount of such Additional Letter of Credit shall be the
amount of such draw. Failure by Tenant to timely deliver to Landlord such Additional Letter of Credit shall be a default not susceptible
of cure, entitling Landlord to exercise any and all remedies hereunder on account thereof.

 

In
the event Tenant fails timely to deliver to Landlord a Substitute Letter of Credit. then Landlord shall have the right, at any
time after such event, without giving any further notice to Tenant, to draw down the Letter of Credit and to hold the proceeds
thereof (the “Security Proceeds”) in accordance with this Section 4.2. If Landlord draws down the Letter
of Credit pursuant to this Section, then:

 

(1)          Such
draw and Landlord’s right to hold the Security Proceeds pursuant to this Section shall be Landlord’s sole remedy based
on Tenant’s failure to timely deliver a Substitute Letter of Credit as required hereunder; and

 

(2)          Upon the expiration or prior termination of the
Lease Term, Landlord shall return to Tenant any Security Proceeds then being held by Landlord, to the extent that any such Security
Proceeds exceed the amounts then due from Tenant to Landlord.

 

To
the extent that Landlord has not previously drawn upon any Letter of Credit or Security Proceeds (collectively, the “Collateral”)
held by Landlord, and to the extent that Tenant is not otherwise in default of its obligations under this Lease as of the expiration
of the Lease Term, Landlord shall return such Collateral to Tenant at the expiration of the Lease Term.

(ii)           Workmen’s Compensation covering all Tenant’s
employees, contractors and agents working on the Premises.

 

(iii)          Casualty insurance against damage to or loss
of any and all trade fixtures and equipment (including without limitation, all laboratory equipment, vents, hoods, etc.) installed
by Tenant in the Premises during the Lease Term, in an amount at least equal to the replacement cost of such trade fixtures and
equipment;

 

(iv)         Such additional insurance (including, without
limitation, rent loss insurance) as Landlord or Landlord’s Mortgagee shall reasonably require, provided that such insurance
is in an amount and of the type customarily carried in Massachusetts by prudent occupants of similar property.

 

6.2         Writing
and Disposition of Insurance Policies. All insurance required under Section 6.1 above shall be written with companies
reasonably satisfactory to Landlord and in forms customarily in use from time to time in the Greater Boston area, and shall cover
the entirety of the Premises and all trade fixtures and equipment (including without limitation, all laboratory equipment, vents,
hoods, etc.) located therein, notwithstanding that various clients of Tenant shall be occupying portions of the Premises, as permitted
pursuant to Article 11 below. Tenant shall furnish Landlord with duplicates of said policies, and said policies shall (i)
name Landlord and Landlord’s Mortgagee as additional insureds, as their respective interests may appear, and (ii) provide
that the coverage thereunder may not lapse or be canceled without thirty (30) days prior written notice to Landlord, Landlord’s
Mortgagee and Tenant.

 

6.3         Mutual
Waiver of Subrogation. Landlord and Tenant each hereby releases the other, its officers, directors, employees and agents,
from any and all liability or responsibility (to the other or anyone claiming through or under them by way of subrogation or otherwise)
for any loss or damage to property covered by valid and collectible insurance, even if such loss or damage shall have been caused
by the fault or negligence of the other party, or anyone for whom such party may be responsible. However, this release shall be
applicable and in force and effect only with respect to loss or damage (a) actually recovered from an insurance company and (b)
occurring during such time as the releasor’s insurance policies shall contain a clause or endorsement to the effect that
any such release shall not adversely affect or impair said policies or prejudice the right of the releasor to recover thereunder.
Landlord and Tenant each agrees that any fire and extended coverage insurance policies will include such a clause or endorsement
as long as the same shall be obtainable without extra costs, or, if extra cost shall be charged therefor, so long as the other
party pays such extra cost. If extra cost shall be chargeable therefor, each party shall advise the other party and of the amount
of the extra cost, and the other party, at its election, may pay the same, but shall not be obligated to do so.

 

6.4         Blanket
Policies. Nothing contained herein shall prevent Tenant from taking out insurance of the kind and in the amounts provided
for herein under a blanket insurance policy or policies covering properties other than the Premises, provided however, that any
such policy or policies of blanket insurance (a) shall specify therein, or Tenant shall furnish Landlord with the written
statement from the insurers under such policy or policies, specifying the amount of the total insurance allocated to the Premises,
which amounts shall not be less than the amounts required herein, and (b) amounts so specified shall be sufficient to prevent
any of the insureds from being a co-insurer within the terms of the applicable policy or policies, and provided further, however,
that any such policy or policies of blanket insurance shall, as to the Premises, otherwise comply as to endorsements and coverage
with the provisions herein.

Requirements”), except that Tenant may defer compliance so long as the validity of any such Legal Requirement shall
be contested by Tenant in good faith and by appropriate legal proceedings, and:

 

(i)           If by the terms of such Legal Requirement, compliance
therewith pending the prosecution of any such proceeding may legally be delayed without the incurrence of any lien, charge or
liability of any kind against the Premises or Site and without subjecting Tenant or Landlord to any liability, civil or criminal,
for failure so to comply therewith, Tenant may delay compliance therewith until the final determination of such proceeding, or

 

(ii)          If any lien, charge or civil liability would
be incurred by reason of any such delay, Tenant nevertheless may contest as aforesaid and delay as aforesaid, provided that such
delay would not subject Landlord to criminal liability or fine, and Tenant (a) furnishes to Landlord security, reasonably satisfactory
to Landlord, against any loss or injury by reason of such contest or delay, and (b) prosecutes the contest with due diligence;
and

 

(iii)         Such delay in compliance will not constitute
a default by Landlord under any lease, mortgage or other agreement, will not affect the use of all or any portion of the Site
by Landlord or any tenant of the Site, and will not affect the sale, leasing, or refinancing of all or any portion of the Site.

EXECUTION VERSION

 

7.7         Personal Property at Tenant’s Risk.
That all personal property, equipment, inventory and the like from time to time upon the Premises shall be at the sole risk of

thereof. Any alteration, addition or improvement in, on, or to the Premises made or installed by Tenant shall become a part of
the realty and belong to Landlord without compensation to Tenant upon the expiration or sooner termination of the Term, at which
time title shall pass to Landlord under this Lease as if by a bill of sale, unless Landlord elects otherwise and notifies Tenant
to remove any such tenant improvements at any time prior to the expiration of the Lease Term. Notwithstanding the foregoing, any
and all trade equipment (including but not limited to manufacturing and processing equipment), trade fixtures, furniture, data
lines, inventory and business equipment shall remain Tenant’s property and shall be removed by Tenant at the expiration
or earlier termination of this Lease. Upon demand by Landlord, Tenant shall remove, at Tenant’s sole cost and expense, forthwith

additions or improvements which are designated by Landlord to be removed, and Tenant shall forthwith and with all due diligence,
at its sole cost and expense, repair any damage to the Premises or the Building or the Site caused by such removal. In the event
Tenant fails so to remove any such alterations, additions and improvements or fails to repair any such damage to the Premises,
the Building or the Site, Landlord may do so and collect from Tenant the cost of such removal and repair in accordance with Section
7.8 hereof.

 

7.10      
Rights of Mortgagees.

 

(i)          This
Lease shall be subordinate to any mortgage, deed of trust or ground lease or similar encumbrance (collectively, a “Mortgage”)
from time to time encumbering the Premises, whether executed and delivered prior to or subsequent to the date of this Lease, unless
Landlord’s Mortgagee shall elect otherwise. If this Lease is subordinate to any Mortgage and Landlord’s Mortgagee
or any other party shall succeed to the interest of Landlord pursuant to the Mortgage (such Mortgagee or other party, a “Successor”),
at the election of the Successor, Tenant shall attorn to the Successor and this Lease shall continue in full force and effect
between the Successor and Tenant. Not more than fifteen (15) days after Landlord’s written request, Tenant agrees to execute
such instruments of subordination or attornment in confirmation of the foregoing agreement as the Successor reasonably may request,
and Tenant hereby appoints the Successor as Tenant’s attorney-in-fact to execute such subordination or attornment agreement
upon Tenant’s failure timely to comply with the Successor’s request. Notwithstanding the foregoing, if this Lease
is subordinate to a Mortgage as aforesaid, then Landlord shall use commercially reasonable efforts to obtain the written
agreement of Landlord’s Mortgagee that, subject to such reasonable qualifications as such Mortgagee may impose, in the event
that Landlord’s Mortgagee or any other party shall succeed to the interest of Landlord hereunder pursuant to such Mortgage,
so long as no Event of Default exists hereunder, Tenant’s right to possession of the Premises shall not be disturbed and
Tenant’s other rights hereunder shall not be adversely affected by any foreclosure of such Mortgage. For purposes hereof,
the term “commercially reasonable efforts” shall not include the payment of any sum of money or the consent to less
favorable terms and conditions with respect to the obligations or indebtedness secured or created by the Mortgage. In the event
that, despite using commercially reasonable efforts, Landlord is unable to obtain such an agreement, then this Lease nonetheless
shall be subordinate as aforesaid.

EXECUTION VERSION

 

(ii)         With reference to any assignment by Landlord
of Landlord’s interest in this Lease, or the rents payable hereunder, conditional in nature or otherwise, which assignment
is made to the holder of a mortgage on property which includes the Premises, Tenant agrees that the execution thereof by Landlord,
and the acceptance thereof by the holder of such mortgage shall never be treated as an assumption by such holder of any of the
obligations of Landlord hereunder unless such holder shall, by notice sent to Tenant, specifically otherwise elect and, except
as aforesaid, such holder shall be treated as having assumed Landlord’s obligations hereunder only upon foreclosure of such
holder’s mortgage and the taking of possession of the Premises. In no event shall the acquisition of Landlord’s interest
in the Site by a purchaser which, simultaneously therewith, leases Landlord’s entire interest in the Site back to the seller
thereof be treated as an assumption by operation of law or otherwise, of Landlord’s obligations hereunder, but Tenant shall
look solely to such seller lessee, and its successors from time to time in title, for performance of Landlord’s obligations
hereunder. In any such event, this Lease shall be subject and subordinate to the lease to such purchaser. For all purposes, such
seller lessee, and its successors in title, shall be the Landlord hereunder unless and until Landlord’s position shall have
been assumed by such purchaser lessor. Except as provided herein, in the event of any transfer of title to the Site by Landlord,
Landlord shall thereafter be entirely freed and relieved from the performance and observance of all covenants and obligations
hereunder.

 

(iii)        Tenant shall not seek to enforce any remedy it
may have for any default on the part of Landlord without first giving written notice by certified mail, return receipt requested,
specifying the default in reasonable detail to any mortgage holder whose address has been given to Tenant, and affording such
mortgage holder a reasonable opportunity to perform Landlord’s obligations hereunder. Notwithstanding any such attornment or subordination
of a mortgage to this Lease, the holder of any mortgage shall not be liable for any acts of any previous landlord, shall not be
obligated to install any tenant improvements, and shall not be bound by any amendment to which it did not consent in writing nor
any payment of rent made more than one month in advance.

 

7.11       Estoppel
Certificates. From time to time, upon not less than fifteen (15) days prior written request by Landlord, to execute, acknowledge
and deliver to Landlord, for delivery to a prospective purchaser or mortgagee of the Premises or the Site or to any assignee of
any mortgage of the Premises or the Site, a statement in writing certifying: (a) that this Lease is unamended (or, if there have
been any amendments, stating the amendments); (b) that it is then in full force and effect, if that be the fact; (c) the dates
to which Rent and any other payments to Landlord have been paid; (d) any defenses, offsets and counterclaims which Tenant,
at the time of the execution of said statement, believes that Tenant has with respect to Tenant’s obligation to pay Rent
and to perform any other obligations under this Lease or that there are none, if that be the fact; and (e) such other data as
may reasonably be requested. Any such statement may be relied upon by such prospective purchaser or mortgagee of the Premises,
or portion thereof, or any assignee of any mortgagee of the Premises, or portion thereof.

    17

7.12       Nuisance. At all times during the Lease
Term and such further time as Tenant occupies the Premises, not to injure, overload, deface or otherwise harm the Premises; nor
commit any nuisance; nor to do or suffer any waste to the Premises; nor permit the emission of any objectionable noise or odor
outside of the Building; nor make any use of the Premises which is improper, or contrary to any Legal Requirement or which will
invalidate any insurance policy covering the Premises or any portion thereof, including, without limitation, the handling, storage
and disposal of any hazardous material. Notwithstanding anything herein to the contrary, Landlord hereby warrants and represents
that the floor load of the first floor of the Premises shall be adequate to support the Haas SL-10 Computer Numerical Controlled
Lathe and the Fanuc Robodrill αD21MiA5 currently utilized by Tenant in its business operations (“Tenant’s
Equipment”).

 

7.13       Changes and Alterations. Except as otherwise
explicitly set forth herein, Tenant shall have no authority, without the express written consent of Landlord, to alter, remodel,
reconstruct, demolish, add to, improve or otherwise change the Premises, except that Tenant shall have such authority, without
the consent of Landlord, to make repairs to the Premises and do such things as are appropriate to comply with the obligations
imposed on Tenant under other provisions of this Lease.

 

              Tenant
shall not construct or permit any alterations, installations, additions or improvements including any exterior signs (“Alterations”)
to the Premises or the Building without having first submitted to Landlord plans and specifications therefor for Landlord’s
approval, which approval shall not be unreasonably withheld or delayed provided that:

 

(i)          if the improvement involves a sign or will otherwise
be visible from the exterior, then the improvement must be compatible with the architectural and aesthetic qualities of the Premises
and the Site; and

 

(ii)         the improvement must be non-structural and have
no effect on the plumbing, heating and cooling, mechanical, electrical or other systems or services in the Premises or the Building,
and the improvement (except for signs) must be entirely within the Premises; and

 

(iii)        the
change, when completed, will not adversely affect the value of the Premises or the Site; and

 

(iv)        Tenant demonstrates to Landlord’s satisfaction
that the improvement will be made in accordance with all applicable Legal Requirements, using good quality materials and good
quality construction practices, and will not result in any liens on the Premises; and

    18

     

    
EXECUTION VERSION

 

(v)         as soon as such work is completed, Tenant will
have prepared and provide Landlord with “as-built” plans (in form acceptable to Landlord) showing all such work; and

 

(vi)        Tenant will comply with any rules or requirements
reasonably promulgated by Landlord in connection with the doing of any work, and if requested by Landlord, Tenant will obtain
and maintain Builder’s Risk insurance in connection with such work.

 

Tenant
shall have the right to make minor alterations from time to time in the Premises without obtaining Landlord’s prior written
consent therefor, provided that all of such work conforms to all of the above requirements in all respects, and further provided
that Tenant provides Landlord with a written description of such work (and such other data as Landlord may request) prior to commencing
any such alteration, and further provided that the aggregate cost of such minor alterations may not exceed $50,000 in any twelve
(12) month period.

 

Furthermore,
notwithstanding anything herein to the contrary, Tenant, at its sole cost and expense, shall have the right to install its logo
sign, as depicted on Exhibit F hereto, on the façade of the Building, provided that (A) such sign is in compliance
with local zoning regulations and Tenant obtains any consents or approvals required by third parties; and (B) Tenant shall be
solely responsible for removing such sign upon the expiration or any earlier termination of the Lease in accordance with Section
7.9 above. Landlord shall cooperate with Tenant in connection with obtaining any consents or approvals required by third parties;
provided, however, that Landlord shall not be required to incur any expense or liability in connection therewith. Otherwise Tenant
shall not place on the exterior of the Premises (including both interior and exterior surfaces of doors and interior surfaces
of windows) or on any part of the Building, any signs, symbol, advertisement or the like visible to public view.

 

7.14       Financial
Statements. So long as Tenant is a corporation whose stock is traded on a public exchange, Tenant shall not be required to
furnish Landlord with financial statements. Tenant’s statement of net worth, as reported in its annual report to its shareholders
or in any forms required to be submitted to the Securities and Exchange Commission, shall be acceptable in lieu of any financial
statements otherwise required hereunder and shall be conclusive with respect to the items reported therein. In the event that
Tenant’s stock is not traded on a public exchange, upon written request of Landlord (which shall not be made more frequently
than once in any calendar year, unless an Event of Default has occurred hereunder or Landlord intends to sell or refinance the
Property or any portion thereof), Tenant shall furnish Landlord a management-prepared statement of income and balance sheet and
statement of cash flow for the immediately preceding fiscal quarter or fiscal year, as the case may be, prepared in accordance
with generally accepted accounting principles consistently applied.

 

7.15       Holdover.
If Tenant remains in the Premises beyond the expiration of the Lease Term, or sooner following an early termination as provided
for herein, such holding over shall not be deemed to create any tenancy, but Tenant shall be a tenant at sufferance only subject
to all of Tenant obligations set forth herein, but at a daily rate equal to one hundred fifty percent (150%) of the Rent, the
cost of electricity and all other utilities supplied to the Premises, and other charges provided for under this Lease. The acceptance
of a purported rent check following termination shall not constitute the creation of a tenancy at will, it being agreed that Tenant’s status
shall remain that of a tenant at sufferance, at the aforesaid daily rate. Any reference in this Lease to Tenant’s obligations
continuing during the period of any holdover shall not be deemed to grant Tenant the right to a holdover or imply Landlord’s consent
to any such holdover. In addition, Tenant shall be liable for all costs, claims, liabilities and damages arising from or in any
manner related to any such holdover including, without limitation, damages payable to the subsequent tenant and related to the
loss of a tenant.

are made suitable for Tenant’s occupancy, and the Lease Term shall be extended, without the necessity of further action
by any party, for a period equal to the time during which Rent so abated. In the event of any casualty or damage to the Premises,
Landlord shall proceed at its expense and with reasonable diligence to repair and restore the Premises (to the extent originally
constructed by Landlord) to substantially the same condition they were in immediately prior to such damage or casualty. Notwithstanding
the foregoing, if Landlord, in its sole discretion, determines that timely restoration is not possible or practical or that there
are or will be insufficient insurance proceeds available to Landlord to accomplish same, then Landlord shall have the right to
terminate this Lease by written notice given to Tenant within ninety (90) days after the occurrence of any Substantial Casualty.
In the event the Premises have not been restored to the condition required pursuant to the terms of this Lease within two hundred
seventy (270) days following any damage or casualty, then either Landlord or Tenant may terminate this Lease by written notice
given to the other within five (5) business days following such two hundred seventy (270) day period. In addition, in the event
Landlord has failed to commence the restoration of the Premises within one hundred eighty (180) days following any damage or casualty,
then Tenant may terminate this Lease by written notice given to Landlord at any time following such one hundred eighty (180) day
period (provided, however, that no such notice of termination shall be valid if given after Landlord has actually commenced such
restoration).

9.2         Eminent
Domain. Landlord reserves for itself all rights to any damages or awards with respect to the Premises and the leasehold estate
hereby created by reason of any exercise of the right of eminent domain, or by reason of anything lawfully done in pursuance
of any public or other authority; and by way of confirmation Tenant grants and assigns to Landlord all Tenant’s rights to
such damages so reserved, except as otherwise provided herein. Tenant covenants to execute and deliver any instruments confirming
such assignment as Landlord may from time to time reasonably request. Tenant may, however, at its own cost and expense, make a
separate claim (which shall, if required by law, be consolidated with Landlord’s claim) to the condemnor for any of Tenant’s
moveable fixtures and personal property so taken, for the unamortized value of leasehold improvements paid for by Tenant (exclusive
of Landlord’s claim for the residual value thereof) and for relocation expenses. If all the Premises are taken by eminent
domain, this Lease shall terminate when Tenant is required to vacate the Premises or such earlier date as Tenant is required to
begin the payments of rent to the taking authority. If a partial taking by eminent domain results in so much of the Premises being
taken as to render the Premises or a material portion thereof unsuitable for Tenant’s continued use and occupancy as determined
by Landlord in its reasonable discretion, either Landlord or Tenant may elect to terminate this Lease as of the date when Tenant
is required to vacate the portion of the Premises so taken, by written notice to the other given not more than ninety (90) days
after the date on which Tenant or Landlord, as the case may be, receives notice of the taking. If a partial taking by eminent
domain does not result in such portion of the Premises as aforesaid being taken, then this Lease shall not be terminated or otherwise
affected by any exercise of the right of eminent domain. Whenever any portion of the Premises shall be taken by any exercise of
the right of eminent domain, and if this Lease shall not be terminated in accordance with the provisions of this Section 9.2,
Landlord shall, at its expense, proceeding with all reasonable dispatch, provided sufficient condemnation proceeds are available
therefor (or, if not, provided Tenant provides additional funds needed above the amount of the condemnation proceeds available)
do such work as may be required to restore the Premises or what remains thereof (not including Tenant’s trade fixtures,
business equipment and furniture) as nearly as may be to the condition they were in immediately prior to such taking, and Tenant
shall at its expense, proceeding with all reasonable dispatch, do such work to its trade fixtures, business equipment and furniture,
as may be required. A just proportion of the Rent payable hereunder, according to the nature and extent of the taking shall be
abated from the time Tenant is required to vacate that portion of the Premises taken. If the Premises have not been restored to
a condition substantially suitable for their intended purpose within two hundred seventy (270) days of said taking, Tenant may
elect to terminate this Lease by written notice to Landlord sent within five (5) business days following such two hundred seventy
(270) day period. In addition, in the event Landlord has failed to commence the restoration of the Premises within one hundred
eighty (180) days following any taking, then Tenant may terminate this Lease by written notice given to Landlord at any time following
such one hundred eighty (180) day period (provided, however, that no such notice of termination shall be valid if given after
Landlord has actually commenced such restoration).

DEFAULTS
BY TENANT AND REMEDIES

 

10.1       Tenant’s
Default. Each of the following shall be an event of default (“Event of Default”) hereunder: (A) if Tenant
shall fail to pay any installment of Base Rent, Additional Rent or any other payment due under this Lease, and such failure shall
continue for a period of seven (7) business days following Landlord’s notice of same to Tenant, provided that such notice
from Landlord shall be in lieu of, and not in addition to, any notice of default required by applicable law, and provided
further Landlord shall be obligated to give only two (2) such notices per any twelve (12) month period, with subsequent payment
default to be an Event of Default if such failure to pay shall continue for a period of seven (7) business from the date such
payment is due (without any notice); (B) if Tenant or any guarantor or surety of Tenant’s obligations hereunder shall (i)
make a general assignment for the benefit of creditors; (ii) commence any proceeding for relief, or seeking reorganization, arrangement,
adjustment, liquidation, dissolution or composition of it or its debts or seeking appointment of a receiver, trustee, custodian
or other similar official for it or for all or of any substantial part of its property; (iii) become the subject of any such proceeding
which is not dismissed within sixty (60) days after its filing or entry; or (iv) die or suffer a legal disability (if Tenant,
guarantor or surety is an individual) or be dissolved or otherwise fail to maintain its legal existence (if Tenant, guarantor
or surety is a corporation, partnership or other entity); (C) Tenant shall fail to discharge or bond over any lien placed upon
the Premises in violation of this Lease within thirty (30) days after Tenant receives notice that any such lien or encumbrance
is filed against the Premises; (D) if Tenant shall fail to comply with any provision of this Lease, other than those specifically
referred to hereinabove and, except as otherwise expressly provided therein, such default shall continue for more than thirty
(30) days after Landlord shall have given Tenant written notice of such default, or such longer period if such default cannot
be reasonably cured within such thirty (30) day period, provided that Tenant diligently commences the cure within the thirty (30)
day period and diligently prosecutes such cure to completion; and (E) if Tenant shall abandon the Premises for more than sixty
(60) days. Upon the occurrence of an Event of Default, defined as aforesaid, then in any such case, notwithstanding any waiver
or other indulgence of any prior default, Landlord may terminate this Lease by written notice to Tenant sent at any time thereafter,
but before Tenant has cured or removed the cause for such termination. Such termination shall take effect on the later of (i)
the last day of the month in which Tenant receives the notice, or (ii) twenty-one (21) days after Tenant receives the notice,
and shall be without prejudice to any remedy Landlord might otherwise have for any prior breach of covenant.

EXECUTION VERSION

 

10.2       Landlord’s
Election. Upon each occurrence of an Event of Default and so long as such Event of Default shall be continuing, Landlord may
at any time thereafter, at its election by written notice to Tenant: (i) terminate this Lease or Tenant’s right of possession,
but Tenant shall remain liable as hereinafter provided; and/or (ii) pursue any remedies provided for under this Lease or at law
or in equity. Upon the termination of this Lease or termination of Tenant’s right of possession, it shall be lawful for
Landlord, without formal demand or notice of any kind, to re-enter the Premises by summary dispossession proceedings or any other
action or proceeding authorized by law and to remove Tenant and all persons and property therefrom. If Landlord re-enters the
Premises, Landlord shall have the right to keep in place and use, or remove and store all of the fixtures, equipment and other
property of Tenant left at the Premises or elsewhere at the Site. If Landlord terminates this Lease or terminates Tenant’s
right of possession, Landlord may recover from Tenant the sum of (i) all Base Rent, Additional Rent and all other amounts accrued
hereunder to the date of such termination, (ii) the costs set forth in Section 10.3 below, and (iii) an amount equal to
(A) the Base Rent and Additional Rent which would have been payable by Tenant under this Lease had this Lease not been so terminated
(or had Tenant’s right of possession not been terminated) for the period commencing after said termination and ending on
the last day of the Lease Term with such amounts becoming due and payable by Tenant on such dates as Base Rent would otherwise
become due and payable hereunder, less (B) the net rents received by Landlord from re-letting the Premises (or any portion(s)
thereof) for the period commencing after said termination and ending on the last day of the Lease Term, such net rents to be determined
by first deducting from the gross rents received by Landlord from such re-letting the expenses incurred or paid by Landlord in
connection with said termination and in re-entering the Premises and in securing possession thereof, as well as the actual expenses
of re-letting (including, without limitation, altering and preparing the Premises for new tenants and any broker’s commission
as determined pursuant to Section 10.3 below). Subject to the provisions of Section 10.5 below, any such re-letting
may be for a shorter or longer period than the remaining Lease Term, and in no event shall Tenant be entitled to receive any excess
of such net rents over the Base Rent payable by Tenant to Landlord under this Lease. Even though Tenant has breached this Lease
and abandoned the Premises, this Lease shall continue in effect for so long as Landlord does not terminate Tenant’s right
to possession, and Landlord may enforce all its rights and remedies under this Lease, including the right to recover Base Rent
and Additional Rent as it becomes due. Any such payments due Landlord shall be made on the dates that Base Rent or such Additional
Rent would otherwise come due under this Lease, and Tenant agrees that Landlord may file suit to recover any sums falling due
from time to time. Notwithstanding any such re-letting without termination, Landlord may at any time thereafter elect in writing
to terminate this Lease for such previous breach. Notwithstanding the foregoing, Landlord may, at its election and in lieu of
the amounts set forth in subclause (iii) above, recover from Tenant, as liquidated damages for the then-unexpired portion of the
Lease Term, a sum that at the time of termination of the Lease on account of such Tenant default or at the time to which installments
of such amounts shall have been paid, represents the excess of the Base Rent and Additional Rent and other payments herein named
over the then-rental value of the Premises for the residue of the Lease Term. Tenant’s liability for sums due pursuant to
this Section 10.2 shall survive any termination of the Lease.

 

10.3       Reimbursement of Landlord’s Expenses.
In the case of termination of this Lease or termination of Tenant’s right of possession pursuant to Section 10.2,
Tenant shall reimburse Landlord for all actual expenses arising out of such termination, including, without limitation, (i) all
costs actually incurred in collecting such amounts due from Tenant under this Lease (including reasonable attorneys’ fees
actually incurred and the costs of litigation and the like but only if Landlord is successful in its litigation), (ii) all customary
and necessary expenses incurred by Landlord in attempting to relet the Premises or parts thereof (including advertisements, brokerage
commissions, tenant’s allowances, lease inducements, costs of preparing space, and the like), and (iii) all Landlord’s
other expenditures necessitated by the termination. The reimbursement from Tenant shall be due and payable within thirty (30)
days following written notice from Landlord that an expense has been incurred with documentation substantiating such expenses,
without regard to whether the expense was incurred before or after the termination.

EXECUTION VERSION

 

10.4       Termination
of Right of Possession. Even though Tenant has breached this Lease and abandoned the Premises, this Lease shall continue in
effect for so long as Landlord does not terminate the Lease (even though it has terminated Tenant’s right of possession),
and Landlord may enforce all its rights and remedies under this Lease, including the right to recover Base Rent and Additional
Rent as it becomes due. Any such payments due Landlord shall be made on the dates that Base Rent and Additional Rent would otherwise
come due under this Lease, and Tenant agrees that Landlord may file suit to recover any sums falling due from time to time. Notwithstanding
any such termination of possession only, Landlord may at any time thereafter elect in writing to terminate this Lease for such
previous breach.

 

10.5       Mitigation. Landlord shall use commercially
reasonable efforts to relet the Premises which efforts shall be subject to the reasonable requirements of Landlord to lease to
high quality tenants and to develop the Premises in a harmonious manner with an appropriate mix of uses, tenants, and terms of
tenancies, and the like and factoring in the location and nature of the Premises. It is agreed that hiring a reputable leasing
broker to lease the Premises and cooperating in good faith with such broker shall satisfy the requirement that Landlord use commercially
reasonable efforts to relet.

 

10.6       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 the statute of law in effect at the time when, and governing
the proceedings in which, the damages are to be provided, whether or not the amount is greater to, equal to, or less than the
amount of the loss or damage which Landlord has suffered.

 

10.7       Landlord’s Right to Cure Defaults.
Landlord may, but shall not be obligated to cure, at any time any default by Tenant under this Lease after the applicable notice
and cure period (if any) has expired. In curing such defaults, Landlord may enter upon the Premises and take such action thereon
as may be necessary to effect such cure. In the case of an emergency threatening serious injury to persons or property, Landlord
may cure such default without notice. All costs and expenses incurred by Landlord in curing a default, including reasonable attorneys’
fees actually incurred, together with interest thereon at a rate equal to the lesser of (a) eighteen percent (18%) per annum,
or (b) the highest lawful rate of interest which Landlord may charge to Tenant without violating any applicable law from the day
of payment by Landlord shall be paid by Tenant to Landlord on demand. Landlord may use the Security Deposit to effectuate any
such cure.

 

10.8       No Waiver. Exercise by Landlord of any
one or more remedies hereunder granted or otherwise available shall not be deemed to be an acceptance of surrender of the Premises
and/or a termination of this Lease by Landlord, whether by agreement or by operation of law, it being understood that such surrender
and/or termination can be effected only by the written agreement of Landlord and Tenant. Tenant and Landlord further agree that
forbearance or waiver by either party to enforce its rights pursuant to this Lease, or at law or in equity, shall not be a waiver
of such party’s right to enforce one or more of its rights in connection with any subsequent default. A receipt by Landlord
of rent with knowledge of the breach of any covenant hereof shall not be deemed a waiver of such breach, and no waiver by Landlord
of any provision of this Lease shall be deemed to have been made unless expressed in writing and signed by Landlord. No payment
by Tenant, or acceptance by Landlord, of a lesser amount than shall be due from Tenant to Landlord shall be treated otherwise
than as a payment on account of the earliest installment of any payment due from Tenant under the provisions hereof. The acceptance
by Landlord of a check for a lesser amount with an endorsement or statement thereon, or upon any letter accompanying such check,
that such lesser amount is payment in full, shall be given no effect, and Landlord may accept such check without prejudice to
any other rights or remedies which Landlord may have against Tenant.

EXECUTION VERSION

 

10.9       Late Charge; Default Interest. If any
payment of Base Rent, Additional Rent or any other payment payable hereunder by Tenant to Landlord shall not be paid when due,
Landlord may impose, at its election, a late fee of ten percent (10%) of the overdue amount and interest on the overdue amount
from the date when the same was payable until the date paid at a rate equal to the lesser of (a) eighteen percent (18%) per annum,
or (b) the highest lawful rate of interest which Landlord may charge to Tenant without violating any applicable law (the “Default
Rate”). Such late fee and interest shall constitute Additional Rent payable hereunder.

ASSIGNMENT AND SUBLETTING

 

11.1       Prohibition.
Tenant covenants and agrees that neither this Lease nor the term and estate hereby granted, nor any interest herein or therein,
will be assigned, mortgaged, pledged, encumbered or otherwise transferred, and that neither the Premises, nor any part thereof
will be encumbered in any manner by reason of any act or omission on the part of Tenant, or used or occupied, or utilized for
desk space or for mailing privileges, by anyone other than Tenant, or for any use or purpose other than as stated herein, or be
sublet or offered or advertised for subletting, without the prior written consent of Landlord in each and every case, which consent
shall not be unreasonably withheld, delayed or conditioned. Notwithstanding anything contained herein to the contrary, Tenant
shall have no right to advertise on or about the Building or the Site to assign this Lease or sublet any interest hereunder. Not
in limitation of the foregoing, Tenant’s request for Landlord’s consent to subletting or assignment shall be submitted
in writing no later than sixty (60) days in advance of the proposed effective date of such proposed assignment or sublease, which
request shall be accompanied by the following information (the “Required Information”): (i) the name, current
address and business of the proposed assignee or subtenant; (ii) the precise square footage and location of the portion of
the Premises proposed to be so subleased or assigned; (iii) the effective date and term of the proposed assignment or subletting;

supply Landlord with such financial statements and other information as Landlord may request, prepared in accordance with generally
accepted accounting principles, not more than ninety (90) days old when delivered to Landlord, indicating the net worth, liquidity
and credit worthiness of the proposed assignee or subtenant in order to permit Landlord to evaluate the proposed assignment or
sublease. Tenant agrees to reimburse Landlord for legal fees and any other reasonable expenses and costs incurred by Landlord
in connection with any proposed assignment or subletting.

 

11.2       Conditions
to Consent. Notwithstanding anything to the contrary contained herein, it shall not be unreasonable for Landlord to withhold
its consent to any proposed assignment or sublease if (i) Tenant proposes to assign this Lease or sublease the Premises or any
portion thereof to any person or entity with whom Landlord is then negotiating for the rental of other space at the Site or who
is a tenant in any building at the Site or any other building owned by Landlord or any affiliate of Landlord; or (ii) the net
worth of any such proposed assignee or subtenant is less than the greater of (A) the net worth of Tenant on the date hereof or
(B) the net worth of Tenant at the time of any such assignment or sublease; or (iii) in Landlord’s judgment the proposed
assignee or subtenant is engaged in a business which is not in keeping with the then standards of the Building and the proposed
use is not limited to the Permitted Use; or (iv) there are then two (2) or more leases or subleases in effect with respect
to the Premises (including this Lease); or (v) the proposed sublease is for a portion of the Premises of less than 5,000 rentable
square feet; or (vi) any rent payable by Tenant hereunder is so-called “percentage rent” (provided, however, that
it is hereby agreed and acknowledged that in no event shall Landlord’s right to withhold consent be limited to the basis
set forth in clauses (i) through (vi) above). Landlord’s consent shall be granted only if any and all rights of expansion,
extension, renewal, first offer, and the like contained within this Lease are deleted and/or waived by Tenant, and if requested
by Landlord such assignee or subtenant, and only if the assignee or subtenant shall promptly execute, acknowledge, and deliver
to Landlord an agreement in form and substance satisfactory to Landlord whereby the assignee or subtenant shall agree to be bound
by and upon the covenants, agreements, terms, provisions and conditions set forth in this Lease other than the payment of Rent
hereunder.

11.3       Excess
Rents. If Tenant shall sublet the Premises, having first obtained Landlord’s consent, at a rental in excess of the Base
Rent and Additional Rent due and payable by Tenant under the provisions of this Lease, such excess Rent and Additional Rent net
of Tenant’s commercially reasonable and necessary expenses related to the sublease shall be paid by Tenant to Landlord,
it being agreed, however, that Landlord shall not be responsible for any deficiency if Tenant shall sublet the Premises at a rental
less than that provided for herein.

 

11.4      
Intentionally Omitted.

 

11.5       Assignment or Sublease to an Affiliate.
Notwithstanding anything to the contrary contained herein, Tenant shall have the right to assign this Lease or sublet the Premises
or any part thereof without the prior consent of Landlord to either (x) an entity into or with which Tenant is merged or consolidated,
or to which all or substantially all of Tenant’s assets are transferred, or (y) any entity which controls or is controlled
by Tenant or is under common control with Tenant (“Affiliate”), subject to applicable principles of fraudulent
conveyance, fraudulent transfer or other similar laws and provided that in any such event (i) the successor to Tenant has a net
worth, computed in accordance with generally accepted accounting principles consistently applied, at least equal to the greater
of (1) the net worth of Tenant immediately prior to such merger, consolidation or transfer, or (2) the net worth of Tenant herein
named on the date of this Lease; (ii) proof satisfactory to Landlord of such net worth shall have been delivered to Landlord at
least ten (10) days prior to the effective date of any such transaction, and (iii) the assignee agrees directly with Landlord,
by written instrument in form satisfactory to Landlord in its reasonable discretion, to be bound by all the obligations of Tenant
hereunder, including, without limitation, the covenant against further assignment and subletting.

 

11.6       No
Waiver. If this Lease is assigned, or if the Premises or any part thereof is sublet or occupied by anybody other than Tenant,
Landlord may, after default by Tenant, collect Base Rent and/or Additional Rent from the assignee, subtenant or occupant, and
apply the net amount collected to the Base Rent and/or Additional Rent herein reserved, but no such assignment, subletting, occupancy
or collection shall be deemed a waiver of this covenant, or the acceptance of the assignee, subtenant or occupant as a tenant,
or a release of Tenant from the further performance by Tenant of covenants on the part of Tenant herein contained. The consent
by Landlord to an assignment or subletting shall not in any way be construed to relieve Tenant from obtaining the express consent
in writing of Landlord to any further assignment or subletting. No assignment, subletting or use of the Premises shall affect
the Permitted Use hereunder. Notwithstanding any permitted assignment or subletting, Tenant shall at all times remain directly,
primarily and fully responsible and liable for the payment of all sums payable hereunder and for compliance with all the obligations
of Tenant hereunder.

CONDITION OF PREMISES

 

17.1       As
Is. The Premises are being delivered to Tenant in their “as is” condition, except as expressly set forth in this
Article.

 

17.2       Landlord’s Work; Base Building Work.
Landlord shall perform certain leasehold improvements to the Premises (“Landlord’s Work”), in accordance
with plans and specifications to be mutually agreed upon by Landlord and Tenant (the “Plans”), which Plans
shall be deemed to constitute an exhibit hereto and shall be incorporated herein upon completion. Landlord agrees to reimburse
Tenant for up to Three Thousand Two Hundred and 00/100 Dollars ($3,200.00) of the out-of-pocket costs actually incurred by Tenant
in connection with the preparation of the Plans. Landlord’s Work shall be performed in accordance with the Plans, in a good
and workmanlike manner, in compliance with all applicable laws and codes and using materials and installations meeting Landlord’s
minimum standards for the Building. Landlord shall use commercially diligent efforts to complete any punch-list items that remain
to be performed by Landlord, if any, within thirty (30) days of the Term Commencement Date. The Tenant shall notify Landlord within
sixty (60) days of the Term Commencement Date of any portion of Landlord’s Work, including punch-list items, that remains
incomplete or any manner in which the Premises is not in the condition required to be delivered pursuant to this Lease. Except
as identified in any such notice from Tenant to Landlord, Tenant shall have no right to make any claim that Landlord has failed
to perform any of Landlord’s Work fully, properly and in accordance with the terms of the Lease or to require Landlord to
perform any further Landlord’s Work.

 

In
addition, Landlord shall, at its sole cost and expense, (i) upgrade the front entrance to the Building; (ii) reconfigure the stairs;
(iii) install a new handicapped lift, and (iv) install a new loading ramp at the back entrance to the Building adequate for Tenant’s
Equipment (collectively, the “Base Building Work”). The Base Building Work shall be performed in a good and
workmanlike manner, in compliance with all applicable laws and codes and using materials and installations meeting Landlord’s
minimum standards for the Building.

 

17.3       Cost
of Landlord’s Work. Landlord shall pay for the cost of Landlord’s Work, up to a maximum aggregate amount of Nine
Hundred Sixty Thousand and 00/100 Dollars ($960,000.00) (“Landlord’s Contribution”). Tenant agrees that
it shall be responsible for payment of any costs and expenses incurred by Landlord on account of Landlord’s Work that exceed
Landlord’s Contribution (the “Excess Costs”). Tenant shall, if requested by Landlord, execute a work
letter confirming such Excess Costs prior to the time Landlord shall be required to commence any portion of Landlord’s Work
to which such Excess Costs relate, and Landlord shall have no obligation to commence such work unless and until Tenant shall have
paid such Excess Costs, as estimated by Landlord’s contractor, to Landlord. In the event that the Excess Costs are greater than
the estimate of Landlord’s contractor, then Tenant shall pay to Landlord such difference within ten (10) days after Landlord
advises Tenant of such actual cost. In the event that the actual cost to Landlord is less than the estimate of Landlord’s
contractor, then Landlord shall refund or credit Tenant with such difference, to the extent actually paid by Tenant, within ten (10)
days after such actual cost are finally determined. Landlord shall be entitled to the same rights and remedies for any failure
of Tenant to pay the Excess Costs to Landlord as are available to Landlord in the event of any failure by Tenant to pay Rent when
the same is due. Tenant shall be entitled to credit against Base Rent due within six (6) months of the Rent Commencement Date
one-half (1/2) of the portion of Landlord’s Contribution, if any, not utilized for Landlord’s Work. No portion of

19.2       Environmental Requirements. The term “Environmental
Requirements” means all Legal Requirements regulating or relating to health, safety, or environmental conditions on,
under, or about the Premises or the Site, including without limitation the following, all as may have been amended from time to
time: (a) the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA); (b) the Clean Air Act; (c) the Clean
Water Act; (d) the Resource Conservation and Recovery Act; (e) the Toxic Substances Control Act; (f) all ordinances, orders, rules
and regulations promulgated pursuant to any of the foregoing, and all state and local counterparts of the foregoing, including

contaminant that is or could be regulated under any Environmental Requirement or that may adversely affect human health or the
environment, including without limitation any solid and hazardous waste, hazardous substance, asbestos, petroleum (including oil,
natural gas, synthetic gas, polychlorinated biphenyls [PCBs], and radioactive material), and any pathogen or viral or biological
material. For purposes of Environmental Requirements, to the extent authorized by law, Tenant shall be deemed to be the responsible
party, including the “owner” and “operator” of Tenant’s “facility” and the owner of
all Hazardous Materials brought on the Premises or the Site by Tenant or any Tenant Party, and the wastes, by-products, or residues
generated, resulting or produced therefrom.

 

19.3       Removal of Hazardous Materials. Tenant,
at its sole cost and expense, shall remove all Hazardous Materials disposed of or otherwise released by Tenant or any Tenant Party

in compliance with all Environmental Requirements and in a manner that does not limit any future uses of the Premises or the Site.
Tenant shall perform such removal at any time during the Lease Term upon written request by Landlord, or in any event, prior to
expiration or earlier termination of this Lease. If Tenant fails to perform such removal within the time period requested by Landlord
or in any event before expiration or earlier termination of this Lease, then Landlord may, at its discretion, and without waiving
any other remedy available under this Lease or at law or equity, perform such work at Tenant’s expense. Tenant shall pay
all costs incurred by Landlord in performing such work within ten (10) days following Landlord’s written request therefor.
Any such work performed by Landlord shall be on behalf of Tenant, and Tenant shall remain at all times the owner, generator, operator,
transporter, and/or arranger of the Hazardous Materials for purposes of Environmental Requirements. Tenant agrees that it shall
not enter into any agreement with any person, contractor, or governmental authority regarding the removal of Hazardous Materials
that have been disposed of or otherwise released onto or from the Premises or the Site without the written approval of Landlord.

 

19.4

as well as actual legal fees, consultant and expert fees), which are brought or recoverable against, suffered or incurred
by Landlord as a result of any release or threat of release of Hazardous Materials or any breach of the requirements of this Article
19 by Tenant or any Tenant Party, regardless of whether Tenant had knowledge of such noncompliance or breach. The obligations

that tenant has not so complied with any Environmental Requirement or the terms of this Article, in which case, Tenant shall reimburse
Landlord for the actual costs of such inspections or tests within ten (10) days of Landlord’s demand therefor. Tenant shall
promptly notify Landlord of any communication or report that Tenant makes to any governmental authority regarding any possible

EXTENSION OPTION

 

20.1       Option
to Extend Lease Term. Tenant shall have the right and option, which said option shall not be severed from this Lease or separately
assigned, mortgaged or transferred, at its election, to extend the Original Lease Term for one (1) additional period of five (5)
years (the “Extension Period”) commencing upon the expiration of the Original Lease Term, provided that (a)
Landlord shall receive written notice from Tenant of the exercise of its election at least twelve (12) months prior to the expiration
of the Original Lease Term, but no sooner than fifteen (15) months prior to the expiration of the Original Lease Term; (b)
no Event of Default shall exist at the time of Landlord’s receipt of such notice and at the expiration of the Original Lease
Term; and (c) the original Tenant named herein or any Affiliate is itself occupying the entire Premises both at the time of giving
the applicable notice and at the commencement of the Extension Period. Notwithstanding the foregoing, in the event that there
is a monetary Event of Default by Tenant two (2) or more times during any five (5) year period (even if subsequently cured by
Tenant), then the extension option set forth herein shall automatically terminate and shall be of no further force and effect.
If Landlord shall receive notice of the exercise of the election in the manner and within the time provided aforesaid, the Original
Lease Term shall be extended upon the receipt of the notice without the requirement of any action on the part of Landlord or Tenant,
except as may be required in order to determine Base Rent as hereinafter provided. Except for the amount of Base Rent (which is
to be determined as hereinafter provided), all the terms, covenants, conditions, provisions and agreements contained in this Lease
shall be applicable to the Extension Period, except that there shall be no further options to extend the Lease Term nor shall
Landlord be obligated to make or pay for any improvements to the Premises nor pay any inducement payments of any kind or nature.
Landlord hereby reserves the right, exercisable by Landlord in its sole discretion, to waive (in writing) any condition precedent
set forth in clauses (a), (b) or (c) above. Time is of the essence with respect to the exercise of the option contained herein.
Tenant shall not have the right to give any notice exercising such option after the expiration of the applicable time limitation
set forth herein, and any notice given after such time limitation purporting to exercise such option shall be void and of no force
or effect.

    32

     

    

EXECUTION VERSION

 

20.2       Determination of Option Rent. The Base
Rent payable hereunder for each Lease Year during the Extension Period shall be adjusted as of the commencement of the such Extension
Period so as to equal the then “fair market rent” for the Extension Period (“fair market rent” to include
annual rent increases), as mutually determined by Landlord and Tenant through the process of negotiation, but in no event shall
the “fair market rent” be less than the Base Rent per annum for and with respect to the last twelve (12) calendar
months of the Original Lease Term. Notwithstanding anything to the contrary contained herein, however, if for any reason Landlord
and Tenant shall not agree in writing upon the “fair market rent” for the Extension Period at least six (6) months
prior to the commencement of the Extension Period, then the fair market rent for premises of the size and nature of the Premises
shall be determined by licensed real estate brokers having at least ten (10) years’ experience in the leasing of commercial
real estate in the Greater Boston, Massachusetts area who are Members of the Appraisal Institute, one such broker to be designated
by each of Landlord and Tenant. All references to “fair market rent” in this Section 20.2, whether determined
by Landlord, Tenant or any broker, shall include a “fair market rent” which includes annual increases during each
Lease Year of the Extension Period. If either party shall fail to designate its broker by giving notice of the name of such broker
to the other party within fifteen (15) days after receiving notice of the name of the other party’s broker, then the broker
chosen by the other party shall determine the fair market rent and his determination shall be final and conclusive. If the brokers
designated by Landlord and Tenant shall disagree as to the fair market rent, but if the difference between their estimates of
fair market rent shall be five percent (5%) or less of the greater of the estimates, then the average of their estimates shall
be the fair market rent for purposes hereof. If the brokers designated by Landlord and Tenant shall disagree as to the amount
of fair market rent, and if their estimates of fair market rent shall vary by more than five percent (5%) of the greater of said
estimates, then they shall jointly select a third broker meeting the qualifications set forth above, and his estimate of fair
market rent shall be the fair market rent for purposes hereof if it is not greater than the greater of the other two estimates
and not less than the lesser of the other two estimates. If said third broker’s estimate is greater than the greater of
the other two estimates, then the greater of the other two estimates shall be the fair market rent for purposes hereof; and if
the estimate of the third broker shall be less than the lesser of the other two estimates, then the lesser of the other two estimates
shall be the fair market rent for purposes hereof. Each of Landlord and Tenant shall pay for the services of its broker, and if
a third broker shall be chosen, then each of Landlord and Tenant shall pay for one-half of the services of the third broker.

		Re:	Amended and Restated Offer Letter

 

Dear Shai:

 

The investor directors and the independent
directors of the Board of Directors (the “Board”) of Markforged, Inc. (“Markforged” or the “Company”)
are pleased to present you with this Amended and Restated Offer Letter, which will govern your continuing at-will employment with
the Company effective as of October 22, 2020 (the “Effective Date”) subject to the terms and conditions below. The
Board values your significant contributions to the Company’s growth and is excited to continue working with you in this new
role.

 

1.             Position: As of the Effective Date, you will serve as the President and Chief Executive Officer of the Company (“CEO”).
This is a full-time, exempt position that reports to the Board. You are required to work cooperatively with the Company’s
executives, including the Chairman. You will also serve on the Board, subject to applicable Board governance documents, for so
long as you remain the CEO, provided that you will be deemed to have resigned from the Board and from any related positions upon
ceasing to serve as CEO for any reason. While you render services to the Company, you agree that you will not engage in any other
employment, consulting or other business activity without the written consent of the Board.

 

2.             Cash Compensation:  Your base salary will be paid at the rate of $500,000 per year, which may be subject to increases
from time to time in the discretion of the Company. Your base salary in effect at any given time is referred to herein as “Base
Salary.” The Base Salary shall be payable in a manner that is consistent with the Company’s usual payroll practices
for executive officers.

 

With respect to your 2020 annual bonus,
the Board has determined that you have met 100% of the goals related to the period between January 1 and June 30, 2020, and, although
no specific KPI’s were agreed upon by you and the Board for the period between July 1 and December 31, 2020, the Board will
assume that you have achieved 100% of such goals. Your 2020 bonus will be paid no later than March 15, 2021. Your annual bonus
eligibility will continue to be $200,000 per year, subject to the Company’s determination as provided below. The target annual
bonus in effect at any given time is referred to herein as the “Target Bonus.” The actual amount of the annual bonus,
if any, shall be determined in the sole discretion of the Board or the Compensation Committee of the Board, subject to the terms
of any applicable incentive compensation plan that may be in effect from time to time. Except as provided in Section 7(b) below
or as may be provided by the Board or the Compensation Committee, you must be employed by the Company on the date the bonus is
paid in order to earn or receive any bonus. The Company may from time to time adopt one or more bonus plans governing the payment
of the bonus.

     

     

    

 

 

In addition, you will be eligible for a
special milestone bonus of up to $100,000 per calendar year (the “Special Milestone Bonuses”), to be paid on a quarterly
basis (up to $25,000 per quarter), based on the Board’s assessment of your achievement of measurable KPIs s to be established
by the Board after consultation with you. Any quarterly payment of a Special Milestone Bonus will be paid to you within 30 days
following the Board’s determination with respect to achievement of the applicable milestones and the amount of the quarterly
payment (if any) to be awarded. You must be employed on the date of payment to earn any portion of the Special Milestone Bonus.

 

3.           
True-Up Option: Subject to customary approval by the Board, and as mutually agreed upon consideration for noncompetition
provisions set forth in the attached Confidentiality, Assignment, Nonsolicitation and Noncompetition Agreement (the “Nondisclosure
and Noncompetition Agreement”), the Company shall grant you a stock option under the Company’s 2013 Stock Incentive
Plan (the “Plan”) to purchase 2,961,167 shares of common stock (which, together with all other equity awards previously
granted to you, represents 4.25% of the fully-diluted shares outstanding) at a price per share equal to the fair market value established
at the time of Board approval (the “ True-Up Option”). 25% of the shares underlying the True-Up Option will vest on
the first anniversary of the Effective Date, and the remaining shares will vest in 36 equal monthly installments thereafter over
a total vesting period of four years, provided that you remain an employee of the Company on each such vesting date. The True-Up
Option will be subject to the terms of the Plan and subject to and contingent upon your execution of a stock option agreement (the
 “Stock Option Agreement”, together with the Plan and your existing equity awards, the “Equity Documents”).
The Stock Option Agreement shall expressly provide that, following the termination of your employment for any reason other than
for Cause (as defined below), the shares underlying the Option may be exercised, to the extent then vested, for a period of one
year following the date of termination (but no later than the expiration date of the Option). Notwithstanding anything to the contrary
in the Equity Documents, if after the consummation of a Change in Control Transaction (as defined below), you are terminated without
Cause (as defined below), then 100% of the then unvested shares underlying the Option and your previously granted equity awards
shall become vested.

 

4.            
Other Benefits: In addition to your compensation set forth above, during your employment, you will be eligible to participate
in the employee benefit plans made generally available by the Company from time to time to its employees, subject to plan terms
and generally applicable Company policies.

 

5.            
Relocation: You acknowledge and agree that you are required to relocate your primary residence from New Jersey to the
Boston, MA area at such time as a COVID-19 vaccine becomes reasonably available to you and your family. Your failure to do so will
be considered a material breach by you of this letter agreement and, notwithstanding any other term of this letter agreement, the
Company may terminate your employment without any further financial liability to you as if you had been terminated for Cause, as
defined below. At the time of such relocation:

 

		(a)	the Board will make reasonable, good faith efforts to help you obtain liquidity of up to $1,000,000
to the extent you have not already achieved such liquidity including, without limitation, upon any acquisition of the Company by
a special purpose entity. To the extent that you have received liquidity in an amount less than $1,000,000 at the time of the relocation,
the Board will make reasonable, good faith efforts to help you obtain liquidity of the difference between the liquidity you have
then achieved and $1,000,000.

     

     

    

 

 

		(b)	the Company shall cover the following: (i) reasonable costs of movers to transfer your household
belonging to the Boston area; (ii) commission for house sale (assumed to be approximately 6% of $1,000,000); (iii) reasonable hotel
costs, if needed, for any gap between permanent housings; (iv) travel costs and accommodations until relocation to Boston. These
reimbursements shall be tax grossed up if needed.

 

6.           
Travel: Prior to relocating your primary residence to the Boston, MA area, you are required to work regularly from the
Company’s Watertown, MA offices. You also will be required to travel from time to time, consistent with the Company’s
business needs. International travel on Company business may be on business class; all other business travel shall be on coach.

 

7.            
Severance Upon a Qualifying Termination: If you have a Qualifying Termination and you satisfy the Release Requirement,
the Company shall pay or otherwise provide the following to you:

 

		(a)	The Company shall pay you on regular payroll dates for the Severance Period at the rate of your
Base Salary on the date of termination (the “Severance Pay”); provided that (i) the Company may commence payments of
Severance Pay at any time within 60 days after the date of termination; (ii) if such sixty (60) day period crosses two calendar
years, payments of the Severance Pay shall commence in the second calendar year; and (iii) the initial payment of the Severance
Pay shall include a catch-up payment for the period between the date of termination and the beginning of the payroll period applicable
to the first payroll date. You shall promptly notify the Company if you secure Other Employment and you shall respond fully to
any reasonable inquiries by the Company that relate to its rights to cease Severance Pay in the event you commence Other Employment.
The Severance Pay will be subject to tax and other withholdings as required by law. Each payment pursuant to this letter agreement
is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2).

 

		(b)	If your Qualifying Termination occurs between the end of a calendar year and the date of payouts
of bonuses for such calendar year, the Company shall pay you the bonus for such recently completed calendar year. If the Company
has determined such bonus level before the Qualifying Termination, the bonus shall be paid in such amount. If the Company has not
determined such bonus level before the Qualifying Termination, the Company shall determine such bonus level in good faith and pay
such amount upon determination.

 

For the avoidance of doubt, each of the
foregoing is subject to your satisfaction of the Release Requirement.

     

     

    

 

 

8.             Definitions:

 

(a)            “Cause” means any of the following: (i) conduct by you constituting an act of misconduct in connection with

notice of such non-performance from the Board; (v) a breach by you of any of the provisions of the Nondisclosure and Noncompetition
Agreement; (vi) a violation by you of the Company’s written employment policies; or (vii) failure to cooperate with a bona fide

to cooperate, or the destruction or failure to preserve documents or other materials known to be relevant to such investigation
or the inducement of others to fail to cooperate or to produce documents or other materials in connection with such investigation.

prior to such transaction or series of transactions constitute the holders of a majority of the voting stock outstanding immediately
following such transaction or series of transactions and specifically excluding a direct issuance of the securities by the Company
where the principal business purpose is financing).

 

(c)            “Continuing Obligations” means your obligations pursuant to the Nondisclosure and Noncompetition Agreement and
any other agreement relating to confidentiality, assignment of inventions, or other restrictive covenants.

 

(d)            “Good Reason” means that you have complied with the Good Reason Process (hereinafter defined) following the
occurrence of any of the following events: (i) a material diminution in your Base Salary except for across-the-board salary reductions
based on the Company’s financial performance similarly affecting all or substantially all senior management employees of the Company;
(ii) a material diminution in your responsibilities, authority or duties; (iii) a material change in the principal geographic location
at which you are required to provide services to the Company; or (iv) the material breach of this letter agreement by the Company.

     

     

    

 

 

(e)            “Good Reason Process” means that (i) you reasonably determine in good faith that a “Good Reason” condition
has occurred; (ii) you notify the Company in writing of the first occurrence of the Good Reason condition within 30 days of the
first occurrence of such condition; (iii) you cooperate in good faith with the Company’s efforts, for a period not less than 30
days following such notice (the “Cure Period”), to remedy the condition; (iv) notwithstanding such efforts, the Good
Reason condition continues to exist; and (v) you terminate your employment within 60 days after the end of the Cure Period. If
the Company cures the Good Reason condition during the Cure Period, Good Reason shall be deemed not to have occurred.

 

(f)             “Other Employment” means employment on a more than half-time basis. For these purposes, any service as an “employee”

(h)            “Release Requirement” means the requirement that, as a condition of receiving the payments set forth in Section

without limitation, a release of legal claims and a non-disparagement obligation and will provide that all payments of Severance
Pay shall immediately cease if you breach any of your Continuing Obligations, and (ii) the separation agreement becomes irrevocable
within 60 days after the date of termination or such short period as set forth in the separation agreement.

 

(i)             “Severance Period” means the period immediately following the date of termination of employment until the earlier
of (i) twelve months from the date of termination or (ii) the date immediately before you commence Other Employment.

 

9.             
Section 409A: Each payment pursuant to the terms of this letter agreement shall be considered a separate payment for
purposes of Internal Revenue Code Section 409A (“Section 409A”). A termination of employment shall not be deemed to have
occurred for purposes of any provision of this letter agreement providing for the payment of any amount or benefit upon or following
a termination of employment unless such termination is also a “separation from service” within the meaning of Section
409A and, for purposes of this letter agreement, references to a “termination,” “termination of employment”
or like terms shall mean “separation from service.” Notwithstanding anything to the contrary in this letter agreement,
if you are a “specified employee” (within the meaning of Section 409A) on the date of your separation from service, then
any payments or benefits that otherwise would be payable pursuant to the terms of this letter agreement within the first six (6)
months following your separation from service (the “409A Suspension Period”), shall instead be paid in a lump sum within
14 days after the end of the six (6) month period following your separation from service, or your death, if sooner, but only to
the extent that such payments or benefits provide for the “deferral of compensation” within the meaning of Section 409A,
after application of the exemptions provided in Sections 1.409A-1(b)(4) and 1.409A-1(b)(9)(ii)-(v) thereof. After the 409A Suspension
Period, you will receive any remaining payments and benefits due in accordance with the terms of this letter (as if there had not
been any suspension beforehand). The Company will cooperate with you in making any amendments to this letter that you reasonably
request to avoid the imposition of taxes or penalties under Section 409A of the Code provided that such changes do not provide
you with additional benefits (other than de minimis benefits) under this terms of this letter.

     

     

    

 

 

10.           Cooperation: During and after your employment, you shall cooperate with the Company including without limitation in
connection with (i) the defense or prosecution of any claims or actions now in existence or which may be brought in the future
against or on behalf of the Company which relate to events or occurrences that transpired while you were employed by the Company,
provided the Board will make reasonable good faith efforts to limit your future involvement in litigation matters to the extent
it is able to do so consistent with its fiduciary duties to the Company; and (ii) the investigation, whether internal or external,
