are in substitution for Taxes as now imposed on the Building, the Land, the Premises or this Lease. 
  
 Section 6.05 - Accounting Periods. Landlord may from time to time change the periods of accounting under this Lease to any annual period

Landlord will render a supplemental statement in which appropriate adjustment will be made. 
  
 Section 6.06 - Abatement of Taxes. Landlord may at any time and from time to time make application to the appropriate Governmental Authority of an abatement of Taxes. Landlord agrees to make such an

made any payment in respect of Taxes under this Article 6 for the period with respect to which the abatement was granted, Landlord agrees (a) to deduct from the amount of the abatement all expenses incurred by it in connection with the application
(b) within thirty (30) days after receipt of the abatement amount to pay to Tenant Tenant’s Share (adjusted for any period for which Tenant had made a partial payment) of the abatement, with interest, if any, paid by the Governmental Authority
on such abatement, and (c) retain the balance, if any.

exempt from taxes under the United States Internal Revenue Code. If Tenant is able to establish to Landlord’s satisfaction the amount of the reduction in Taxes during any calendar year which is a result of this Lease and Tenant’s
tax-exempt status, Tenant’s obligation to pay Taxes for such calendar year as provided in this Article 6 will abate in the same amount, or the amount, if previously paid, will be refunded to Tenant. If Tenant is not tax-exempt but
Landlord’s obligation to pay Taxes is abated because of the tax-exempt status of any other tenant or tenants of the Building, Landlord reserves the right to increase Tenant’s Share as it relates to Taxes so that the Taxes payable with
respect to the Land and the Building for any calendar year during the Lease Term are equitably apportioned among the tenants of the Building who are not exempt from taxation.

 (d) Such greater limits and such other insurance and in such amounts as may from time to time be reasonably required by Landlord against
other insurable hazards which at the time are customarily insured against in the case of buildings similarly situated and used. 
  
 Section 15.02 - General Insurance Provisions. 
  
 (a) All insurance provided for in Section 15.01 will be written as primary policies (without “contribution” or “solely in
excess of coverage carried by Lessor” provisions) and will be effected under valid and enforceable policies, 
  

	*	See Rider and Addendum - 17 

  

 – 23 – 

 issued by insurers of recognized responsibility authorized to write such insurance in Massachusetts and
having a Best’s financial rating of B or better. Not less than five (5) days before the Term Commencement Date, and thereafter not less than ten (10) days before the expiration dates of the expiring policies furnished under to Section 15.01,
binders, certificates or other evidence of such insurance satisfactory to Landlord bearing notations evidencing the payment of premiums or accompanied by other evidence satisfactory to Landlord of such payment, will be delivered by Tenant to
Landlord. 
  
 (b) Nothing in this Article 15 will
prevent Tenant from taking out insurance of the kind and in the amounts provided for under this Article under a blanket insurance policy or policies covering other properties as well as the Premises. Any policy or policies of blanket insurance (i)
will specify, or Tenant will furnish Landlord with a written statement from the insurers specifying, the amounts of the total insurance allocated to the Premises, which amounts will not be less than the amounts required by Section 15.01 and will be
sufficient to prevent any of the insureds from becoming a co-insurer within the terms of the applicable policy or policies, (ii) will contain an “Agreed Amount” clause as to the Premises and (iii) will otherwise comply as to endorsements
and coverage with the provisions of this Article. 
  
 (c) All policies of insurance provided for in Section 15.01 will name Landlord and Tenant as the insured, as their respective interests may appear, and also the Ground Lessor and any mortgagee, when requested, as their respective interests
may appear, except that Landlord, the Ground Lessor and any such mortgagee will have no interest in the insurance on Tenant’s personal property. Each such policy or certificate issued by the insurer will, to the extent obtainable, contain an
agreement by the insurer that the insurance will not be cancelled without at least twenty (20) days prior written notice to Landlord and to any other named insureds. Landlord agrees not to carry any insurance concurrent in coverage and contributing
in the event of loss with any insurance required to be furnished by Tenant if the effect of such separate insurance would be to reduce the protection or the payment to be made under Tenant’s insurance. 
  
 Section 15.03 - Landlord’s Insurance. Landlord agrees to
cause the Building (including Landlord’s Fixtures but excluding any Improvements and leasehold improvements (a) by any tenant prior to their completion, or (b) which any tenant may be required to remove upon termination of its lease) to be
insured for the benefit of Landlord, the Ground Lessor and any mortgagee of Landlord, as their respective interests may appear, against loss or damage under a so-called “All Risk” policy in an amount equal 

  

 – 24 – 

 
to (i) the replacement value or (ii) the amount necessary to avoid the effect of co-insurance provisions of the applicable policies. Land_ord also agrees to
maintain comprehensive form boiler insurance, rental value insurance and such other insurance against such perils and in such amounts as may be required by the Ground Lessor or any mortgagee of Landlord or as Landlord may consider prudent. The cost
of such insurance will be part of the Operating Expenses. 
  
 ARTICLE 16 
  
 Waiver of Subrogation

  
 Section 16.01 - Waiver of Subrogation. If
available, all insurance policies carried by either party covering the Building and/or the Premises will contain a clause or endorsement expressly waiving any right on the part of the insurer to make any claim against the other party and against the
Ground Lessor. The parties agree to use reasonable efforts to insure that their policies will include such waiver clause or endorsement. 
  
 Section 16.02 - Waiver of Rights. Landlord and Tenant each waive all claims, causes of action and rights of recovery against the other and
against the Ground Lessor and their respective partners, agents, officers and employees, for any loss or damage to persons, property or business which occurs on or about the Premises or the Building and results from any of the perils insured under
any policy of insurance maintained by Landlord and/or Tenant, regardless of cause. This waiver includes the negligence and intentional wrongdoing of either party and their respective agents, officers and employees but is effective only to the extent
of recovery, if any, under any such policy. This waiver will be void to the extent that any such insurance is invalidated by reason of this waiver. 
  
 ARTICLE 17 
  
 Damage and Restoration 
  
 Section 17.01 - Substantial Damage. If the Building is damaged by fire or other casualty, Tenant agrees to give prompt written notice to Landlord. If as a result of fire or other casualty, (i) the
Building is so damaged that substantial alteration or reconstruction of the Building is, in Landlord’s sole opinion, required (whether or not the Premises have been damaged), or (ii) the Ground Lease is terminated, or (iii) any mortgagee of the
Building requires that all or a substantial portion of insurance proceeds payable be used to retire the mortgage debt, Landlord may, at its option, terminate this Lease by giving notice to Tenant within Sixty (60) days after the date of the damage.
If, within sixty (60) days after the date of the 

  

 – 25 – 

 
damage, Landlord does not begin to restore the Building as provided in Section 17.02 or notify Tenant of its election to terminate this Lease, Tenant may
terminate this Lease by giving notice to Landlord within ten (10) days after this expiration of the sixty (60) days period. If this Lease is terminated by Landlord or Tenant as provided in this Section 17.01, Rent will be abated as of the date of
the damage. 
  
 Section 17.02 - Restoration. If
Landlord does not terminate this Lease as provided in Section 17.01 within sixty (60) days after the date of the damage, Landlord agrees to begin to restore the Building to substantially the same condition in which it was immediately before the
damage, and, subject to Unavoidable Delays, to continue the restoration with reasonable diligence. Landlord’s restoration work will include Landlord’s Fixtures, the scope of the work done by Landlord in originally finishing the Premises
according to the Working Drawings and subsequent Improvements made by Tenant under the provisions of Section 7.06 which are to remain part of the Premises. Landlord will not be required to rebuild, repair, or replace (i) any part of Tenant’s
furniture, furnishings or equipment, or (ii) any Improvements made by Tenant which Tenant is required to remove on the Lease Termination Date under Section 7.06. Landlord will not be liable for any inconvenience or annoyance to Tenant or injury to
the business of Tenant resulting from the damage to or the repair of the Building, except that Landlord will allow Tenant a fair reduction of Rent to the occurrence of the damage to a date thirty (30) days after completion of Landlord’s
repairs. 
  
 ARTICLE 18 
  
 Eminent Domain 
  
 Section 18.01 - Total Taking. If there is a Total Taking, then
this Lease will terminate as of the earlier to occur of (i) the date when physical possession of the Building or the Premises is taken by the condemning Governmental Authority or (ii) the date when title vests in the condemning Governmental
Authority. 
  
 Section 18.02 - Partial Taking. If
there is a Taking of the Premises which is not a Total Taking, Landlord may terminate this Lease by giving notice to Tenant within sixty (60) days after receiving notice of the Taking, in which event this Lease will terminate as of the earlier to
occur of (i) the date when physical possession of such portion of the Premises is taken by the condemning Governmental Authority or (ii) the date when title vests in the condemning Governmental Authority. If this Lease is not terminated, Rent will
be abated from the date the Premises are rendered unfit for occupancy by an amount representing that part of the Rent properly allocable to the portion of the Premises taken, and Landlord will, at Landlord’s expense, restore the 

  

 – 26 – 

 
Building and the Premises to substantially their former condition to the extent that restoration, in Landlord’s judgment, may be feasible.
Landlord’s restoration work will not exceed the scope of Tenant Fit-up as shown in the Working Drawings and subsequent Improvements made by Tenant under the provisions of Section 7.06 which are to remain part of the Premises. 
  
 Section 18.03 - Awards and Proceeds. All proceeds payable in
respect of a Taking will be the property of Landlord. Tenant hereby assigns to Landlord all rights of Tenant in or to such awards and proceeds, provided that Tenant will be entitled to separately petition the condemning authority for a separate
award for its moving expenses and trade fixtures but only if such a separate award will not diminish the amount of award or proceeds payable to Landlord. 
  
 ARTICLE 19 
  
 Quiet Enjoyment 
  
 Section 19.01 - Landlord’s Covenant. Landlord covenants that it has good title to the Premises and the Common Areas, subject to the Permitted Exceptions, and that it has sufficient authority to
enter into this Lease. Landlord also covenants that if Tenant pays the Rent and performs all of its obligations under this Lease, subject to the Permitted Exceptions, it will quietly have and enjoy the Premises during the Lease Term, without
interference from any Person lawfully claiming under Landlord or by paramount title. Landlord agrees that it will pay and perform all of its obligations under the Ground Lease. 
  
 Section 19.02 - Subordination and Non-Disturbance. This Lease is subordinate to (i) the Ground Lease and (ii)
any mortgage now or hereafter on the building and to each advance made under any such mortgage, and to all renewals, modifications, consolidations, replacements and extensions of such mortgage. This Section 19.02 is self-operative and no further
instrument of Subordination will be required, provided that before a future subordination is effective Landlord will cause the mortgagee or Ground Lessor to deliver to Tenant an non-disturbance agreement, binding upon itself and any successor in
interest, to the effect that no foreclouser of the mortgage or termination of the Ground Lease will disturb the possession of Tenant under this Lease so long as on Event of Default exists. In confirmation of such subordination, Tenant agrees to
execute and deliver promptly any certificate that Landlord or the Ground Lessor or any mortgagee may request. If any mortgagee or Ground Lessor succeeds to the interest of Landlord and agrees to recognize the interest of Tenant under this Lease,
Tenant agrees to attorn to such mortgagee or Ground Lessor and to recognize such mortgagee or Ground lessor as its Landlord. 
  

 – 27 – 

 Section 19.03 - Notice to Mortgage and Ground Lessor. No act or failure to act on the part
of Landlord which would entitle Tenant under the terms of this Lease, or by Law, to be relieved of Tenant’s obligations under or to terminate this Lease, will result in a release or termination of such obligations or a termination of this Lease
unless (i) Tenant first gives written notice of Landlord’s act or failure to act to Landlord’s first mortgagee of record, if any, and to the Ground Lessor specifying the act or failure to act on the part of Landlord which could or would
give basis to Tenant’s rights; and (ii) the mortgagee or Ground Lessor, after receipt of such notice, fails or refuses to correct or cure the condition complained of within a reasonable time. Nothing contained in this Section 19.03 will be
deemed to impose any obligation on any mortgagee or Ground Lessor to correct or cure any condition. “Reasonable time” means a period of not less than thirty (30) Business Days and includes (but is not limited to ) a reasonable time to
obtain possession of the Building if the mortgagee or Ground Lessor elects to do so and a reasonable time to correct or cure the condition if the condition is determined to exist. Tenant has no obligation to give notice under this Section 19.03
until the mortgagee or the Ground Lessor has given Tenant notice of its interest as such and the address to which notices under this Section 19.03 are to be sent. 
  
 Section 19.04 - Other Provisions Regarding Mortgagees. If this Lease or the Rent is assigned to a mortgagee as
collateral security for any obligation, the mortgagee will not be deemed to have assumed any of Landlord’s obligations under this Lease solely as a result of the assignment. A mortgagee to whom this Lease has been assigned will be deemed to
have assumed such obligations only if (i) by the terms of the assignment the mortgagee specifically elects to assume the obligations, or (ii) the mortgagee has (a) foreclosed its mortgage, (b) accepted a deed in substitution of foreclosure, or (c)
taken possession of the Premises. Even if the mortgagee assumes the obligations of Landlord, the mortgagee will be liable for breaches of any of Landlord’s obligations only to the extent the breaches occur during the period of ownership by the
mortgagee after foreclosure ( or any conveyance by a deed in substitution of foreclosure) or after entry, and the mortgagee will have no liability for any act or omission or for any obligations incurred by any prior Landlord, including liability
with respect to any Security Deposit except to the extent actually received by such mortgagee. 
  
 ARTICLE 20 
  
 Defaults; Events of Default 
  
 Section 20.1 - Defaults. The following will (i) if any requirement for notice or lapse of time has not been met, constitute Defaults, and (ii) if there are no such requirements or if such requirements have been met, constitute
Events of Default: 
  
 (a) The failure of Tenant
to pay Rent when due, and the continuation of the failure for a period of ten (10) days after notice from Landlord specifying the failure; 
  

 – 28 – 

 (b) The failure of Tenant to perform any of its obligations under this Lease, other than
its obligation to pay Rent, and the continuation of the failure for a period of twenty (20) days after notice from Landlord specifying in reasonable detail the nature of the failure; 
  
 (c) The failure of Tenant to pay Rent when due or to perform any of its obligations under this Lease, if
Landlord has given Tenant notice of the same or similar failure at least twice during the twelve (12) month period preceding the date on which the Rent or performance was due. 
  
 (d) The occurrence with respect to Tenant or any Guarantor of one or more of the following events: the
death, dissolution, termination of existence (other than by merger or consolidation), insolvency, appointment of a receiver for all or substantially all of its property, the making of a fraudulent conveyance or the execution of an assignment or
trust mortgage for the benefit of creditors by it, or the filing of a petition of bankruptcy or the commencement of any proceedings by or against it under a bankruptcy, insolvency or other law relating to the relief or the adjustment of
indebtedness, rehabilitation or reorganization of debtors; provided that if such petition or commencement is involuntarily made against it and is dismissed within sixty (60) days of the date of such filing or commencement, such events will not
constitute an Event of Default; 
  
 (e) The
issuance of any execution or attachment against Tenant or any other occupant of the Premises as a result of which the Premises are taken or occupied by a Person other than Tenant; and 
  
 (f) The cancellation of, refusal to review or denial of liability under any insurance policy relating to the
Premises as a result of the Premises being unoccupied. 
  
 Section 20.2 - Tenant’s Best Efforts. If the Default of which Landlord gives notice is of such a nature that it cannot be cured within twenty (20) days, then the Default will not be deemed to continue so long as Tenant,
after receiving notice of the Default, begins to cure the Default as soon as reasonably possible and continues to take all steps necessary to complete the curing of the Default within time which, under all prevailing circumstances, is reasonable. No
Default will be deemed to continue so long as Tenant is acting to cure the Default in good faith or is delayed in or prevented from curing the Default by reason of Unavoidable Delays.

 ARTICLE 21 

 
 Landlord’s Remedies; Damages on Default 
  
 Section 21.01 - Landlord’s Remedies. Landlord may, at its
option: 
  
 (a) Whenever an Event of Default
exists, give Tenant a notice terminating this Lease on a date specified in the notice. On the date specified in the notice, this Lease and all rights of Tenant under this Lease will end without further notice or lapse of time, but Tenant will
continue to be liable to Landlord as provided in this Article 21. 
  
 (b) If an Event of Default results from Tenant’s failure to pay Tenant’s Cost as required by Section 7.01 and the Work Letter, in addition to or in substitution of the other remedies available to Landlord,
refuse Tenant access to the Premises. In such event the Term Commencement Date will be the earlier of (i) the date determined under Section 7.04 or (ii) the Substantial Completion Date. 
  
 (c) If an Event of Default results from Tenant’s failure to pay a charge for Additional Services,
without further notice to Tenant, discontinue any or all Additional Services. 
  
 Section 21.02 - Possession. Upon termination of this Lease as the result of an Event of Default, Tenant agrees to leave the Premises peacefully and surrender possession to Landlord as provided in Section
9.08. Landlord may, at any time after any termination of this Lease and without further notice, enter the Premises and recover possession by summary proceedings or any other manner permitted by law, and may remove Tenant and all other Persons and
property from the Premises. After termination of this Lease, Landlord will be entitled to receive all rental income from the Premises. 
  
 Section 21.03 - Right to Relet. After termination of this Lease as a result of an Event of Default, Landlord may relet all or any part of
the Premises in the name of Landlord or otherwise, for such term (which may be greater or less than the period which would have constituted the balance of the Lease Term) and on such conditions (which may include concessions or free rent) as
Landlord, in its reasonable discretion, may determine. Landlord agrees to use reasonable efforts but will not be liable for failure to relet the Premises or for failure to collect any rent due upon reletting, and Landlord will not be obligated to
show the Premises in preference to other space available in the Building. 
  

 – 30 – 

 Section 21.04 - Survival of Covenants, Etc. If this Lease is terminated as provided in
Section 21.01: 
  
 (a) The termination will not
relieve Tenant of its obligations under this Lease, which obligations will survive the termination. Tenant agrees to indemnify Landlord against all claims, losses and expenses arising out of the termination. 
  
 (b) At the time of termination, Tenant agrees to pay to
Landlord the Rent up to the date of termination. Tenant also agrees to pay to Landlord, on demand, as liquidated damages for Tenant’s Default, the excess of 
  
 (1) the total Rent that would have been payable under this Lease by Tenant from the date of the termination
until the Stated Expiration Date, over 
  
 (2) the fair and reasonable rental value of the Premises for the same period reduced by Landlord’s reasonable estimate of expenses to be incurred in connection with reletting the Premises, including, without limitation, all
repossession costs, brokerage commissions, legal expenses, reasonable attorneys’ fees, alteration costs, and expenses of preparation for reletting. 
  
 (c) If all or part of the Premises are relet by Landlord, before presentation of proof of such liquidated damages to any court, commission
or tribunal, the amount of rent reserved upon the reletting will be, prima facie, the fair and reasonable rental value for the part or the whole of the Premises relet during the term of the reletting. 
  
 (d) Nothing contained in this Section 21.04 will limit or
prejudice the right of Landlord to prove and obtain as liquidated damages by reason of the termination, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, such
damages are to be proved, whether or not such amount is greater, equal to, or less than the amount determined as provided in clause (b) above. 
  
 Section 21.05 - Right to Equitable Relief. If a Default occurs, Landlord will be entitled to enjoin the Default and may invoke any remedy
allowed at law or in equity as though re-entry, summary proceedings and other remedies were not provided for in this Lease. 
  
 Section 21.06 - Right to Self Help; Interest On Overdue Rent. If an Event of Default occurs, Landlord has the right, but not the obligation,
to enter the Premises and to perform any obligation of Tenant under this Lease notwithstanding the fact that no specific provision for substituted performance by Landlord is made in this Lease. In performing the obligation, Landlord may make any
payment of money or perform any other act. The total of (i) all 

  

 – 31 – 

 
sums paid by Landlord (ii) interest (at the rate of 1-1/2 % per month or the highest rate permitted by law, whichever is less) on such sums plus all Rent not
paid when due and (iii) all expenses in connection with the performance of the obligation by Landlord, will be deemed to the Rent under this Lease and payable to Landlord on demand. Landlord may exercise its rights under this Section 21.05 without
waiving any other of its rights or releasing Tenant from any of its obligations under this Lease. 
  
 ARTICLE 22 
  
 Notices

 ARTICLE 23 
  
 Waivers 
  
 Section 23.01 - No Waivers. Failure of Landlord or Tenant to
complain of any act or omission on the part of the other no matter how long the act or omission may continue, will not be deemed to be a waiver by either Landlord or Tenant at any time, expressed or implied, of the breach of any provision of this
Lease will be deemed a waiver of a breach of any other provision of this Lease or a consent to any subsequent breach of the same or any 

  

 – 32 – 

 
other provision. No acceptance by Landlord of any partial payment will constitute an accord or satisfaction but will only be deemed a partial payment on
account. None of Tenant’s obligations under this Lease and no Default or Event of Default may be waived or modified except in writing by Landlord. 
  
 ARTICLE 24 
  
 Security Deposit 
  
 Section 24.01 - Security Deposit. Tenant has deposited with Landlord the Security Deposit in the amount, if any, stated in Section 1.01. Landlord will hold the Security Deposit as security for the
payment or performance by Tenant of its obligations under this Lease and not as a prepayment of Rent. Landlord may commingle the Security Deposit with other funds of Landlord. Landlord will not be liable to Tenant for the payment of interest.
Landlord may expend such amounts from the Security Deposit as may be necessary to cure any Default or Event of Default and, in such case, Tenant agrees to pay to Landlord the amount expended, on demand. Landlord may assign the Security Deposit to
any subsequent owner of the Building and thereafter Landlord will have no liability to Tenant with respect to the Security Deposit. As soon as reasonably practicable after the Lease Termination Date, Landlord agrees (i) to inspect the Premises, (ii)
to make such payments from the Security Deposit as may be required to reimburse itself for unpaid Rent and all expenses arising out of the termination of the Lease and reletting the Premises and (iii) if no Default or Event of Default has occurred
or exists, pay the balance of the Security Deposit to Tenant. 
  
 ARTICLE 25 
  
 General Provisions

performance of the act will be extended for a period equivalent to the period of the delay.

Improvements comparable in type, quality and quantity, a substantially similar configuration and a rentable area approximately the same as the Premises. Landlord agrees to place the other space in substantially the same condition as the Premises are

the Premises after the Lease Termination Date without having entered into a new lease of the Premises with Landlord, Tenant will be a tenant-at-sufferance only, subject to all of the provisions of this Lease at twice the then effective Basic Rent.
Such holding over, even if with the consent of Landlord, will not constitute an extension or renewal of this Lease. 
  
 Section 25.05 - Governing Law. This Lease and the performance of its provisions will be governed and construed under the laws of the
Commonwealth of Massachusetts. 
  
 Section 25.06 –
Partial Invalidity. If any provision of this Lease or its application to any Person or circumstance is held to be invalid or unenforceable, the remainder of this Lease, or the application of the provision to Persons or circumstances other
than those as to which it is held invalid or unenforceable, will not be affected, and each provision of this Lease will be enforced to the fullest extent permitted by law. 
  
 Section 25.07 - Notice of Lease. At the request of either one, Landlord and Tenant agree to execute promptly
duplicate originals of a statutory notice of lease, in recordable form, setting forth a description of the Premises, the Lease Term and any other terms of this Lease, except the rental provisions, as may be required by law or as either party may
request. 
  
 Section 25.08 - Interpretation. The
section headings used in this Lease are for reference and convenience only, and do not enter into the interpretation of this Lease. This Lease may be signed in several counterparts, each of which is an original, but all of which constitute a single
instrument. The term “Landlord” means only the owner at the time of the Building. Upon any sale of the Building or assignment (other than as collateral security for an obligation) of the interest of Landlord in this Lease,

 – 34 – 

 Landlord will be relieved of all liability under this Lease and its successor in interest and/or assign will be deemed to

 Section 25.09 - Consents. * Except for the consents of Landlord required under Section 7.06 and Article 13, consents or approvals required
or requested of either Landlord or Tenant shall not be unreasonably withheld or delayed.

Lease may not be changed or terminated orally or in any manner other than by an agreement in writing and signed by the party against whom enforcement of the change or termination is sought.

 WORK LETTER 
  
 This Work Letter is attached to and incorporated by reference into a Lease
(the “Lease”) of the Premises in the Building known as Four Biotech Park between WORCESTER BUSINESS DEVELOPMENT CORPORATION (“Landlord”) and UNISYN TECHNOLOGIES, INC. (“Tenant”). Terms in this Work Letter
not otherwise defined have the same meanings as in the Lease. 
  

	 	1.	The provisions of Sections 7.01, 7.02, 7.03, 7.04, 7.05 and 7.06 of the Lease are made part of this Work Letter. 

  

	 	2.	In preparing the Premises for initial occupancy by Tenant, Landlord will provide the space as it exists on the Date of Lease (“Landlord’s Work”). In the Common Areas,
Landlord’s Work includes entrances, main corridor, elevators and lavatory facilities. 

  

	 	3.	At least ten (10) days before the Design Start Date, Landlord will give Tenant a list of information required by Landlord’s architect to prepare a schematic space plan of the
Premises (“Space Plan”). Tenant agrees to meet with Landlord and its architect on or before the Design Start Date and deliver all information necessary to prepare the Space Plan. 

  

	 	4.	Within fifteen (15) days after the Design Start Date, or the date on which Tenant delivers the necessary information, if later, Landlord will deliver to Tenant a copy of the Space
Plan and an estimate of Tenant’s Cost for the work shown on the Space Plan. Within seven (7) days after receipt of the Space Plan and estimate, Tenant will confirm to Landlord that they are approved or give Landlord a detailed explanation of
why they are unacceptable. Landlord and Tenant agree to repeat the procedure outlined in this paragraph 4 until Tenant approves both the Space Plan and the estimate of Tenant’s Cost. 

  

	 	5.	Within thirty (30) days after approval by Tenant of the Space Plan and estimate of Tenant’s Cost, Landlord will deliver to Tenant the Working Drawings prepared by
Landlord’s architect. The cost of preparing the Working Drawings and any subsequent changes requested by Tenant will be included in Tenant’s Cost. 

  

 – 40 – 

	 	6.	Within seven (7) days after receipt by Tenant of the Working Drawings, Tenant will notify Landlord either (i) that the Working Drawings correctly depict the proper layout and design
of all Tenant Fit-up desired by Tenant and Tenant approves the Working Drawings, or (ii) that the Working Drawings vary in design from the approved Space Plan, in which case Landlord will correct the Working Drawings, or (iii) that Tenant wishes to
modify the Working Drawings, in which case Tenant will include with the notification to Landlord a written list of modifications to the Working Drawings. 

  

	 	7.	Promptly upon receipt of Tenant’s approval of the Working Drawings, Landlord agrees to obtain from a qualified contractor a guaranteed maximum price to construct Tenant Fit-up
as shown in the Working Drawings, and to submit to Tenant the final Tenant’s Cost together with a schedule for completion of the work. If Tenant’s Cost, as finally determined, does not exceed Landlord’s estimate by more than ten
percent (10%), Tenant agrees to accept the final determination and authorizes Landlord to proceed with construction of Tenant Fit-up. If Tenant’s Cost exceeds Landlord’s estimate by more than ten percent (10%), the process outlined in
paragraph 6 above will be repeated until Tenant approves Tenant’s Cost. 

  

	 	8.	If Tenant’s Cost exceeds the amount of any allowance agreed to by Landlord, within seven (7) days after the final determination of Tenant’s Cost, Tenant agrees (i) to
deposit an amount equal to that excess in an escrow account which provides for the payment of Tenant’s Cost on terms satisfactory to Landlord, or at Landlord’s option, (ii) to make other arrangements acceptable to Landlord for the payment
of the excess. Landlord will be under no obligation to begin construction of Tenant Fit-up until Tenant has complied with the provisions of this paragraph. 

  

	 	9.	Tenant may request changes in Tenant Fit-up after approval of the Working Drawings and Tenant’s Cost, Changes to the Working Drawings and the work made by Tenant will be priced
at the cost of (i) making such changes to the Working Drawings and (ii) the cost of the work shown thereon (including any contractor’s overhead profit and general conditions). Tenant agrees to pay the cost of all changes made by it.

  

	 	10.	Landlord may rely on Tenant’s representative with respect to all matters which pertain to this Work Letter, Tenant having authorized Tenant’s representative to make
decisions binding upon Tenant with respect to such matters. 

  

 – 41 – 

	 	11.	If Landlord exercises its right to terminate this Lease because of Tenant’s failure to perform any of its obligations, including its obligations under this Work Letter, and if
the termination occurs before the Term Commencement Date, Tenant agrees to pay Landlord, as Additional Rent, (i) an amount equal to the sum of all expenses incurred by Landlord for architectural, engineering, consulting, legal and other professional
services relating to the Premises and this Lease, plus (ii) Basic Rent for the period from the date Tenant accepted Landlord’s letter of intent to lease the Premises through the Lease Termination Date.

 RENT RIDER 
  
 This Rent Rider is attached to and incorporated by reference into a Lease
(the “Lease”) of the Premises in the Building known as Four Biotech Park between WORCESTER BUSINESS DEVELOPMENT CORPORATION (“ Landlord”) and UNISYN TECHNOLOGIES, INC. (“Tenant”). Terms not
otherwise defined have the same meanings in this Rent Rider as in the Lease. 
  
 1. Definitions. Each term set forth in this paragraph 1 has the meaning stated immediately after it. 
  
 Basic Rent. During the first Fixed Rental Period Basic Rent will be the sum of the following amounts: 
  

	 	(a)	For Area A, the sum of (i) $21.00 per square foot of rentable area of Area A, plus (ii) an amount determined by multiplying that portion of Tenant’s Allowance (as defined in
the Rider and Addendum) advanced by Landlord on account of Area A by 17% and dividing the product by the rentable area of Area A; 

  

	 	(b)	For Areas B and C, the sum of (i) $9.00 per square foot of the rentable area of Areas B and C, plus (ii) and amount determined by multiplying that portion of Tenant’s Allowance
advanced by Landlord on account of Areas B and C by 17% and dividing the product by the rentable area of Areas B and C. 

  
 Basic Rent will be increased effective as of the first day of the month following the date on which Landlord makes any advance on account
of Tenant’s Allowance. 
  
 C.P.I.
“Consumer Price Index – All Urban Consumers (CPI-U) – U.S. City Average—All Items (1982-84 = 100)” as published by the U.S. Department of Labor. 
  
 Market Rent. The rent per square foot per year which a Person not affiliated with either Landlord or
Tenant would pay as Basic Rent as of the time of determination (i) for the same number of square feet Rentable Area as the Premises, located in the Building (or a comparable building comparably located), (ii) assuming similar terms and concessions,
if any, to those prevailing at the time, (iii) for a term of years equal to that for which the determination is being made and (iv) for space which is finished in a manner similar to that of the Premises. For purposes of determining Market Rent,
space in the Park leased to tax-exempt organizations or tenants sponsored by Commonwealth BioVentures, Inc. will not be considered comparable. All Additional Rent, such as Taxes and Operating Expenses, will be in addition to the rent per square foot
so determined. 
  

 – 45 – 

 2. Adjustment of Basic Rent. Basic Rent for each Lease Year of each successive Fixed Rental
Period, if any, after the first Fixed Rental Period will be the greater of 
  

	 	(i)	an amount determined by (A) multiplying eighty percent (80%) of Basic Rent for the final Lease Year of the most recent Fixed Rental Period by a fraction, the numerator of which is
the C.P.I. for the last month or other reporting period of the most recent Fixed Rental Period and the denominator of which is the C.P.I. for the last month or other reporting period immediately preceding the Term Commencement Date, and (B) adding
the result to the remaining twenty percent (20%) of such Basic Rent; or 

  

	 	(ii)	an amount determined by increasing Basic Rent as stated in Article 1.01 by three percent (3%) per year, compounded annually for the period beginning on the Term Commencement Date
and ending on the last day of the most recent Fixed Rental Period. 

  
 Basic Rent determined as provided in this paragraph 2 will in no event be less than Basic Rent for each Lease Year of the preceding Fixed Rental Period and will be exclusive of (and in addition to) amounts due for
Taxes and Operating Expenses. 
  
 3. Change in C.P.I.;
Substituted Index. If the United States Department of Labor changes the base reference period for determining the C.P.I., the adjustment of Basic Rent will continue to be calculated with 1982-84 as the base reference period using such figures or
conversion formulas as the United States Department of Labor may publish at the time the base reference period is changed. If publication of the C.P.I. is discontinued, Landlord and Tenant agrees to accept comparable statistics on the cost of living
as they are computed and published by a Governmental Authority or if such statistics are not published by a Governmental Authority, comparable statistics published by a responsible financial periodical of recognized authority selected by Landlord.
If comparable statistics are used in place of the C.P.I., Landlord will make such reasonable revisions in the method of computation of Basic Rent as the circumstances may require to carry out the intent of this Rent Rider and will give Tenant notice
of the revisions before using them. 
  
 4. Market Rent;
Arbitration. 
  
 (a) At least ninety (90)
(but not earlier than one hundred twenty (120)) days before the end of each Fixed Rental Period, Landlord will notify Tenant of Landlord’s estimate of the Market Rent for the Premises. Landlord and Tenant will attempt to negotiate and determine
by agreement the Market Rent for the Premises. If a dispute arises between Landlord and Tenant with respect to the determination 

  

 – 46 – 

 
of Market Rent or if Landlord and Tenant have not agreed on such amount by the date which is sixty (60) days before the end of the then current Fixed Rental
Period, such dispute will be determined exclusively by the arbitrators appointed under this paragraph 4. 
  
 (b) If Market Rent is to be determined by the arbitrators, either Landlord or Tenant may give the other party a notice appointing an
arbitrator and demanding arbitration under this paragraph. Within fifteen (15) days after receipt of such notice, the other party will, by notice to the original party, appoint a second arbitrator on its behalf. If within thirty (30) days after the
appointment of the second arbitrator, the two arbitrators have not agreed upon the Market Rent, the two arbitrators will appoint a third and give notice of the appointment to each party. Each arbitrator must be a disinterested person of recognized
competence in the field of commercial real estate leasing. The three arbitrators will, as promptly as possible, determine the Market Rent, provided that 
  

	 	(i)	if the second arbitrator is not appointed in the manner prescribed, the first arbitrator may determine the matter alone; and 

  

	 	(ii)	if the two arbitrators appointed by the parties are unable to agree, within thirty (30) days after the appointment of the second arbitrator, upon the appointment of a third
arbitrator, they must give notice of such failure to agree to the parties, and, if the parties fail to agree upon the selection of such third arbitrator within fifteen (15) days after notice from the arbitrators, then the third arbitrator will be
the person appointed by the President of the Greater Worcester Board of Realtors, Inc., or if within fifteen (15) days the President fails to appoint an arbitrator, then within ten (10) days thereafter; either of the parties upon notice to the other
party may request such appointment by a judge of the Superior Court, Worcester Country, Commonwealth of Massachusetts, or of any other court having jurisdiction and exercising functions similar to those now exercised by the Superior Court.

  
 (c) Arbitration proceedings
will be conducted in Worcester in accordance with the rules of the American Arbitration Association then in effect, but only so far as consistent with the provisions of this paragraph 4. The arbitrators will be sworn to determine the questions at
issue faithfully and fairly. They will afford each party a hearing and the right to submit evidence with the privilege of cross examination on the questions at issue and will, with all possible speed, make their determination in writing and give the
parties written notice of their determination. If the first two arbitrators fail to decide, the third arbitrator shall make an independent determination of the Market Rent. 

  

 – 47 – 

 
The determination of each of the three arbitrators shall be submitted in writing to Landlord and Tenant. The Market Rent shall be the average of the two
closest determinations submitted by the Arbitrators and shall be final and binding on the parties. 
  
 (d) Landlord and Tenant will each be solely responsible for the payment of all fees and expenses of the arbitrator it appointed, and will
share equally the payment of all fees and expenses of the American Arbitration Association (if any) and of the third arbitrator.

 MASSACHUSETTS BIOTECHNOLOGY
RESEARCH PARK 
 SPACE LEASE 
 to

 UNISYN TECHNOLOGIES, INC. 
  
 RIDER AND ADDENDUM 
  
 The Space Lease from WORCESTER BUSINESS DEVELOPMENT CORPORATION to UNISYN TECHNOLOGIES, INC. to which this Rider and Addendum is attached is
amended by incorporation of the additional provisions contained in this Rider. If there is a conflict between the provisions of the Lease and this Rider, the provisions of this Rider will control. 
  
 1. The Premises and Basic Rent. Although the
Rentable Area of the Premises is 13,788 square feet, the premises will be subdivided into (3) areas called Area A, Area B, and Area C, and Tenant’s obligation to pay Basic Rent with respect to each of the Areas will begin when specified in this
paragraph, notwithstanding any other provision of the Lease to the contrary. The Design Start Date with respect to Area A and Area B is the date specified in Section 1.01. Landlord will have no obligation to begin preparation of Area C for
Tenant’s occupancy until Tenant gives Landlord a notice specifying the Design Start Date with respect to Area C. Subject to extension as a result of delays of the type described in Section 7.04, Landlord agrees that the Substantial Completion
Date with respect to Area C will occur not more than one hundred fifty (150) days after the Design Start Date of Area C. Irrespective of when the obligation to pay Basic Rent begins, Tenant’s obligation to pay Operating Expenses and Taxes for
the entire Premises will begin on the Term Commencement Date. 
  
 (a) Area A. Area A is located on the first floor of the Building substantially as shown on the Lease Plan and has a Rentable Area of 8,104 square feet. Area A will contain the cGMP facility and specialty chemical production suite.
Tenant’s obligation to pay Basic Rent with respect to Area A will begin on the Term Commencement Date. 
  
 (b) Area B. Area B is located on the first floor of the Building substantially as shown on the Lease Plan and has a Rentable Area of 1,280 square
feet. Area B will contain the offices, conference room and lunch room. Tenant’s obligation to pay Basic Rent with respect to Area B will begin on the Term Commencement Date. 
  
 (c) Area C. Area C is located on the first floor of the Building substantially as shown on the Lease Plan and has a
Rentable Area of 4,404 square feet. Tenant agrees to give Landlord notice of the Design Start Date with respect to Area C on or before October 31, 1996. Except for Unavoidable Delays or delays attributable solely to Landlord, and without regard to
the date on which Tenant gives notice of the Design Start Date with respect to Area C, Tenant’s obligation to pay Basic Rent with respect to Area C will begin on the earliest to occur of (i) the Substantial Completion Date with respect to Area
C, (ii) the date 

  

 – 49 – 

 
on which Tenant occupies Area C for the Permitted Use, or (iii) December 31, 1996. 
  
 2. Rentable Area of the Premises. Upon completion of Landlord’s work, the Rentable Area of the Premises
will be determined by Landlord by actual measurement and application of Landlord’s standard method for determining Rentable Area of building in the Park. Landlord agrees to give Tenant notice of the determination of Rentable Area of the
Premises together with a computation of the resulting adjustments, if any, in Basic Rent, Tenant’s Share and Initial Monthly Payment. 
  
 3. Tenant’s Allowance and Payment of Tenant’s Cost. Landlord agrees to make available up to $600,000 which Tenant may, at its
election use to pay Tenant’s Cost in preparing the Premises for Tenant’s occupancy, which amount is referred to in this Lease as “Tenant’s Allowance.” Tenant’s Allowance will consist of two separate funded accounts,
namely Account I in the amount of $400,000, which is applicable to Tenant’s Cost with respect to Area B and Area C, and Account II in the amount of $200,000, which is applicable to the entire Premises. Landlord’s obligation to make Account
I available will expire on October 31, 1996 unless on or before that date Tenant notifies Landlord of its intention to make Improvements and apply Account I to Tenant’s Cost for the Improvements. Tenant will have no right to request funds from
Account I after March 31, 1997. Landlord’s obligation to make Account II available is subject to the closing of permanent financing of the Building known as Three Biotech Park from Teachers Insurance and Annuity Association of America under a
commitment dated April 6, 1995. Tenant will have no right to request funds from Account II after June 30, 1996. 
  
 4. Operating Expenses. Notwithstanding the definition of “Operating Expenses” contained in Section 1.03, the maximum management
fees included in Operating Expenses in any Lease Year will not exceed six percent (6.00%) of Basic Rent. 
  
 5. Tenant’s Self-Help. Notwithstanding the limitations contained in Section 8.04, if Landlord fails to perform any of its
obligations as provided in this Lease, and the failure continues for a period of thirty (30) days after notice from Tenant, Tenant may perform those obligations specified in the notice, and Landlord agrees to reimburse Tenant for any costs incurred
by Tenant in performing those obligations. 
  
 6. Procedure
on Subletting. Notwithstanding the provisions of Section 13.02 to the contrary, if Tenant enters into an Occupancy Arrangement, Tenant agrees to pay to Landlord when received the excess, if any, of amounts received in respect of the
Occupancy Arrangement over the sum of (a) the Rent, plus (b) Tenant’s actual and reasonable out-of-pocket expenses incurred directly in connection with the creation of the Occupancy Arrangement, Plus (c) Tenant’s actual and reasonable
out-of-pocket expenses incurred in compliance with the provisions of Section 7.06 in preparing the Premises for the Occupancy Arrangement. If Tenant intends to enter into an Occupancy Arrangement for a period of two (2) years or less, and if more
than two (2) years remain in the Lease Term at the time the Occupancy Arrangement is to begin, 

  

 – 50 – 

 
Landlord will have no right to terminate this Lease with respect to so much of the Premises as is intended to be subject to the Occupancy Arrangement.

  
 7. Tenant’s Indemnity. Notwithstanding the
provisions of Section 14.03 to the contrary, and except to the extent waived by Tenant under the provisions of Section 16.02, Landlord agrees to indemnify Tenant against all claims, losses and expenses, including reasonable attorneys’ fees,
which may be imposed upon or incurred by Tenant by reason of any of the following occurrences: 
  
 (a) any act or omission on the Premises by Landlord, its agents, contractors, licensees or invitees; 
  
 (b) any condition, operation, maintenance or management of
the Premises which exists exclusively as a result of an act or omission by Landlord, its agents, contractors, licensees or invitees; or 
  
 (c) any act or omission on the part of Landlord, or any of its agents, contractors, licensees or invitees, whether or not occurring on the
Premises. 
  
 8. Right to Relocate. Section 25.03
relating to Landlord’s right to relocate Tenant is deleted in its entirety. 
  
 9. Subordination and Non-Disturbance. At the request of Tenant, Landlord agrees to use reasonable efforts to obtain a non-disturbance agreement from all existing ground lessors and mortgagees having an
interest in the Premises. 
  
 10. Expansion Space.
As used in this paragraph, the term “Expansion Space” means any space in the Building which, at any time during the Lease Term, is occupied by a Person other than Landlord under a written lease with Landlord, and the term
“Tenant’s Expansion Space” means Expansion Space which Tenant has elected to lease as provided in this paragraph. Landlord agrees to notify Tenant promptly after Landlord learns that any Expansion Space is or will become available.
Subject to the prior rights of other tenants to whom Landlord has granted substantially similar rights, Tenant has the option to lease any Expansion Space which Landlord notifies Tenant is or will become available. If Tenant gives Landlord notice of
its exercise of this option within thirty (30) days after notification from Landlord of the availability of the Expansion Space and if no Event of Default exists when Tenant’s notice is given, this Lease will be deemed to be amended to include
Tenant’s Expansion Space as part of the Premises for the remainder of the Lease Term upon all of the same terms contained in this Lease except that (i) the Rentable Area of the Premises will be amended to include Tenant’s Expansion Space;
(ii) Tenant’s Share will be increased to include the rentable area of Tenant’s Expansion Space; (iii) the Term Commencement Date with respect to Tenant’s Expansion Space will be the earlier of sixty (60) days after the date on which
Tenant’s Expansion Space becomes vacant and ready for occupancy (provided that date is at least sixty (60) days after Tenant exercises its option to lease the Expansion Space), or the date on which the Expansion Space is first occupied by
Tenant; (iv) if Tenant’s Expansion Space 

  

 – 51 – 

 
contains a rentable area of 10,000 square feet or more, and if there are less than three (3) Lease Years remaining in the Lease Term, the Lease Term will be
extended to include three (3) full years from the Term Commencement Date with respect to Tenant’s Expansion Space; and (v) subject to adjustment during each Fixed Rental Period as provided in Exhibit E, Basic Rent for each year of the remaining
Lease Term (as it may be extended) will be the greater of (a) the Basic Rent last paid by the Person most recently occupying Tenant’s Expansion Space or (b) Market Rent determined as provided in the Rent Rider attached as Exhibit E. If Tenant
exercises this option, Tenant’s Expansion Space will be leased to Tenant in its “as is” condition and Tenant will, at its expense and in compliance with the provisions of Section 7.06, design and construct all Improvements desired by
Tenant for its use and occupancy. Landlord and Tenant agree to execute such amendments to this Lease and other instruments as either of them considers necessary or desirable to reflect Tenant’s exercise of this option. 
  
 11. Consents. Notwithstanding the provisions of Section 25.09
to the contrary, Landlord will not unreasonably withhold consents of approvals under Section 13.02 if the business of the proposed occupant to be conducted on the Premises is in the biotechnology or biomedical research field and furthers the
purposes for which the park was created.

 8. Defaults. Effective as of the Effective Date, Section 20.1(a) of the Lease is deleted in its
entirety and replaced with the following: 
  
 a.
Tenant shall fail to pay any installment of Rent or any other payment hereunder when due; 
  
 9. Late Payments. Effective as of the Effective Date, Section 21.06(u) of the Lease is deleted in its entirety and replaced with the following: 
  
 “(ii) interest at the annual rate equal to 12% per annum or the highest rate permitted by law (the “Default
Rate”), whichever is less, on all Rent not paid when due and the sums described in clause (i) and” 
  
 In addition, late payment by Tenant to Landlord of Rent and other sums due will cause Landlord to incur costs not contemplated by this Lease, the exact
amount of which will be extremely difficult and impracticable to ascertain. Such costs include, but are not limited to, processing and accounting charges and late charges which may be imposed on Landlord under any mortgage covering the Premises.
Therefore, if any installment of Rent due from Tenant is not received by Landlord within 5 days after the date such payment is due, Tenant shall pay to Landlord an additional sum equal to 6% of the overdue Rent as a late charge. The parties agree
that this late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant. In addition to the late charge, Rent not paid when due shall bear interest at the Default Rate from the 5th day
after the date due until paid.
