 WHEREAS, the Company maintains, from time to time, various stock

NOW THEREFORE, in consideration of the mutual covenants hereinafter set forth, the parties hereto agree as follows: 

1. Issuance of Restricted Shares. The Restricted Shares shall be issued by the Company and held in book entry form and shall be
registered in a restricted account in the Participant’s name on the stock transfer books of the Company promptly after the date hereof. The Participant hereby acknowledges and agrees that the Company shall maintain the registration of the

the Participant’s legal representative. As a condition to the receipt of the Restricted Shares, the Participant shall deliver to the Company a stock power or powers, duly endorsed in blank, relating to the Restricted Shares. No Restricted
Shares shall be issued for fractional shares.

such shares are listed, and any applicable Federal or state laws, and the Committee or, if permitted under the applicable Plan, the Board may cause a legend or legends to be put on any such Restricted Shares to make appropriate reference to such
restrictions. 
 4. Transferability. The Restricted Shares may not, at any time prior to the time the Participant no longer serves as
a director of the Company, be transferred, sold, assigned, pledged, hypothecated or otherwise disposed of unless such transfer, sale, assignment, pledge, hypothecation or other disposition is approved of by the Board. 

 5. Withholding. It shall be a condition of the issuance of the Restricted Shares to the
Participant that the Participant pay to the Company such amount as may be requested by the Company for the purpose of satisfying any liability for any Federal, state or local income or other taxes required by law to be withheld with respect to such
Restricted Shares. The Company shall be authorized to take such action as may be necessary in the opinion of the Company’s counsel (including, without limitation, withholding Restricted Shares otherwise deliverable to Participant hereunder
and/or withholding amounts from any compensation or other amount owing from the Company to the Participant) to satisfy all obligations for the payment of any such taxes. The Participant is hereby advised to seek his or her own tax counsel regarding
the taxation of the grant of Restricted Shares made hereunder.

1. Purchase and Sale. Subject to the terms and conditions set forth in this Agreement, Seller agrees to sell,
transfer and convey to Buyer, and Buyer agrees to purchase and accept from Seller, the following real and personal property (collectively, the “Property”): 

1.1 All that certain land located in Andover, Massachusetts, more particularly described in Exhibit A hereto, together with all
easements and appurtenances belonging to such land, and all right, title and interest (if any) of Seller in and to any streets, alleys, passages, and other rights-of-way or appurtenances included in, adjacent to or used in connection with such land,
and all right, title and interest (if any) of Seller in all development rights appurtenant to such land, and all right title and interest (if any) of Seller in any mineral rights or subsurface rights below such land and any air rights above such
land (the “Land”); 
 1.2 The building known and numbered as 100 Federal Street (the “Building”), together
with all other improvements located on the Land (the Building and such improvements being hereinafter collectively referred to as the “Improvements,” and the Land and the Improvements being hereinafter collectively referred to as
the “Real Property”); 
 1.3 The fixtures, manufacturing and other equipment, machinery, furniture, furnishings, and
appliances attached to, located on or within, or used in connection with the Improvements, or otherwise owned by Seller but excluding those items identified on Exhibit B annexed hereto (which Exhibit B may be revised by Seller upon notice to
Buyer given within ten (10) days following the Effective Date), and located within the Real Property or used exclusively in connection with the Real Property (the “Tangible Personalty”). Buyer expressly agrees and acknowledges
that the Tangible Personalty shall be conveyed in their “as is” condition, without representation or warranty, except as otherwise provided herein, and has no independent resale value, and Buyer and Seller agree that no portion of the
Purchase Price is allocated to such Tangible Personalty, and that no Tangible Personalty shall be sold to Buyer in the event that the Closing (as defined below) does not occur; 

1.4 All of Seller’s rights in all service, management, maintenance, leasing and other contracts affecting the Real Property, Tangible
Personalty, or Intangible Personalty (the “Property Contracts”), to the extent Seller is entitled to transfer the same to Buyer, and that Buyer has not elected to terminate pursuant to Section 5.2 of this Agreement; and 

1.5 All of Seller’s right, title and interest, if any, in all intangible assets of any nature relating to the Land, the Improvements or
the Tangible Personalty, including without limitation all of Seller’s right, title and interest in all (i) warranties and guaranties, express or implied, relating to the Improvements or Tangible Personalty, (ii) all licenses, permits,
and approvals, and (iii) all plans and specifications (the “Intangible Personalty”). 

 2. Purchase Price. The purchase price for the Property (the
“Purchase Price”) shall be Fifteen Million and 00/100 Dollars ($15,000,000.00), which, subject to the terms and conditions hereinafter set forth, shall be paid to Seller by Buyer as follows: 

2.1 Deposit. Concurrently with the execution and delivery of this Agreement by Buyer, Buyer shall deliver to First
American Title Insurance Company (the “Escrow Agent”), in immediately available funds, to be held in escrow and delivered in accordance with this Agreement, a cash deposit in the amount of Five Hundred Thousand and 00/100 Dollars
($500,000.00) (such deposit together with all interest earned thereon, hereinafter collectively referred to as the “Deposit”). The Deposit shall be non-refundable to Buyer except as provided in this Agreement, and shall be held and
distributed as follows: 
 2.1.1 The Deposit shall be held by the Escrow Agent in a segregated interest bearing account at a financial
institution approved in writing by Buyer; provided, however, that until such written approval and a signed IRS form W-9 is received by the Escrow Agent from Buyer, the Deposit will not be placed into such interest bearing account. All interest
earned on the Deposit shall be deemed to be part of the Deposit and shall accrue to the benefit of the party receiving the same. 
 2.1.2 If
the Closing takes place in accordance with the terms and conditions of this Agreement, the Escrow Agent shall deliver and pay the Deposit to Seller on the Closing Date (as defined below), and the original principal amount thereof and all interest
earned thereon shall be credited to Buyer against the Purchase Price due Seller in accordance with the terms and conditions of this Agreement. 

2.1.3 If this Agreement is terminated by Buyer in accordance with the terms and conditions of this Agreement prior to the expiration of the
Inspection Period (as defined below), then the Escrow Agent shall promptly deliver the Deposit to Buyer. 
 2.1.4 If this Agreement is
terminated by Buyer in accordance with the terms and conditions of Section 7 of this Agreement, then the Escrow Agent shall deliver the Deposit to Buyer promptly in accordance with the provisions of this Agreement. 

2.1.5 If the Closing does not take place under this Agreement by reason of the failure of either party to comply with its obligations
hereunder, the Escrow Agent shall promptly deliver the Deposit to the party entitled thereto in accordance with the provisions of this Agreement. 

2.1.6 Except for a demand made by Buyer pursuant to a termination of this Agreement by Buyer prior to the expiration of the Inspection Period,
upon receipt of a written demand from Seller or Buyer claiming the Deposit, the Escrow Agent shall promptly forward written notice of Escrow Agent’s receipt of such demand together with a copy thereof to the other party hereto. Unless such
other party, within ten (10) days after actual receipt of such notice, notifies the Escrow Agent in writing of any objection to such requested delivery of the Deposit, the Escrow Agent shall deliver the Deposit to the party demanding the same
and thereupon shall be released and discharged from any further duty or obligation hereunder by all parties hereto. Notwithstanding anything to the contrary contained herein, the Escrow Agent shall not deliver

  
 2 

 
the Deposit pursuant to any such demand for the same unless and until the Escrow Agent has received confirmation that the party not making the demand for the Deposit has actually received notice
of said demand and that the time for responding to said demand has passed. 
 2.2 Promissory Note. The sum of Five
Million Dollars ($5,000,000.00) shall be paid by delivery of a promissory note at Closing with two payments of $2,500,000 (plus accrued interest at the lowest applicable short-term federal rate) each on or before July 15, 2015 and
January 15, 2016 respectively (the “Note”). Such Note shall be secured by a mortgage on the Real Property granted to Seller and recorded at Closing (the “Seller Mortgage”). The forms of Note and Seller Mortgage
to be entered into at Closing are attached hereto as Exhibit I. Notwithstanding anything herein to the contrary, the outstanding principal balance of the Note shall be immediately due and payable upon any sale of the Property by Buyer. 

2.3 Payment at Closing. At the consummation of the transaction contemplated hereby (the
“Closing”), Buyer shall deliver to the Escrow Agent cash in an amount equal to the Purchase Price less the Note and less the Deposit. The Purchase Price, subject to adjustments and apportionments as set forth herein, shall be paid
at Closing by wire transfer of immediately available federal funds, transferred to the order or account of Seller or such other person as Seller may designate in writing, for receipt by the bank designated by Seller not later than 4
P.M., Boston, Massachusetts Time. 
 3. Escrow Agent. The Escrow Agent shall hold
the Deposit as escrow agent in accordance with the terms and provisions of this Agreement, subject to the following: 
 3.1
Obligations. The Escrow Agent undertakes to perform only such duties as are expressly set forth in this Agreement and no implied duties or obligations shall be read into this Agreement against the Escrow Agent. 

3.2 Reliance. The Escrow Agent may act in reliance upon any writing or instrument or signature which it, in good
faith, believes to be genuine, and any statement or assertion contained in such writing or instrument, and may assume that any person purporting to give any writing, notice, advice, or instrument in connection with the provisions of this Agreement
has been duly authorized to do so. The Escrow Agent shall not be liable in any manner for the sufficiency or correctness as to form, manner and execution, or validity of any instrument deposited in escrow, nor as to the identity, authority, or right
of any person executing the same. 
 3.3 Indemnification. Unless the Escrow Agent discharges any of its duties
under this Agreement in a negligent manner or is guilty of willful misconduct or fraud with regard to its duties under this Agreement, Seller and Buyer shall indemnify the Escrow Agent and hold it harmless from any and all claims, liabilities,
losses, actions, suits or proceedings at law or in equity, or other expenses, fees, or charges of any character or nature, which it may incur or with which it may be threatened by reason of its acting as escrow agent under this Agreement; and in
such connection Seller and Buyer shall indemnify the Escrow Agent against any and all expenses including reasonable attorneys’ fees and the cost of defending any action, suit or proceeding or resisting any claim in such capacity. 

  
 3 

 3.4 Disputes. If the parties (including the Escrow Agent) shall be in
disagreement about the interpretation of this Agreement, or about their respective rights and obligations, or the propriety of any action contemplated by the Escrow Agent, or the application of the Deposit, the Escrow Agent shall have the right to
hold the Deposit until the receipt of written instructions from both Buyer and Seller or a final order of a court of competent jurisdiction. In addition, in any such event, the Escrow Agent may, but shall not be required to, file an action in
interpleader to resolve the disagreement. The Escrow Agent shall be indemnified for all costs and reasonable attorneys’ fees in its capacity as escrow agent hereunder in connection with any such interpleader action and shall be fully protected
in suspending all or part of its activities under this Agreement until a final judgment in the interpleader action is received. 
 3.5
Counsel. The Escrow Agent may consult with counsel of its own choice and have full and complete authorization and protection in accordance with the opinion of such counsel. The Escrow Agent shall otherwise not be liable
for any mistakes of fact or errors of judgment, or for any acts or omissions of any kind, unless caused by its negligence, fraud, or willful misconduct. 

4. Buyer’s Due Diligence Inspection and Termination Rights; “As Is” Sale  

4.1 Inspection of Property. Buyer and its appointed representatives, agents, and independent contractors shall, at
all reasonable times during normal business hours prior to the Closing Date upon prior written notice to Seller, have the privilege of going upon the Property to, at Buyer’s sole cost and expense, inspect, examine, appraise, and survey the
Property, including, but not limited to, inspections of all roofs, electrical, mechanical and structural elements, HVAC systems and other building systems located on or within the Improvements), to perform due diligence (including, without

(as defined below) and compliance with applicable environmental laws), to examine the books and records maintained by Seller with respect to the Property, if any, Property Contracts, insurance policies, tax, utility and other bills, operating
statements and all other general records with respect to the Property (and to make copies thereof), to interview any property managers and service providers of the Property, and to perform such other inspections, investigations, examinations,
appraisals, and surveys with respect to the Property as the Buyer shall deem necessary or appropriate. Notwithstanding anything to the contrary contained herein, the Due Diligence Documents (defined below) and materials reviewed by Buyer pursuant to

information which is the subject of a confidentiality agreement between Seller and a third party (the items described in clauses (i), (ii) (iii), (iv) and (v) being collectively referred to as the “Confidential
Information”). 

  
 4 

 During the Inspection Period, Buyer may perform (x) surveys, architectural, engineering,
geotechnical, property condition and environmental inspections and tests and (y) intrusive or invasive sampling or testing; provided, however, that Buyer shall not perform any invasive sampling or testing of environmental media at the Property
unless recommended in a Phase I environmental report obtained by Buyer and provided to Seller. In the event invasive sampling or testing is so recommended, the scope of the same shall be reasonably acceptable to Seller. To this end, Buyer shall
present to Seller a reasonably detailed description of the invasive sampling and testing, and repairs proposed to be performed, which includes the sampling locations and analyses to be made, prepared by the engineering firm to perform such work.
Buyer shall, and does hereby covenant and agree to, repair any and all damage caused by the activities of Buyer or its agents on the Property and to indemnify, defend and hold Seller harmless from any actions, suits, liens, claims, damages,
expenses, losses and liability arising out of any such entry by Buyer or its appointed agents or independent contractors or any acts performed in exercising Buyer’s rights under this Section 4.1 (including without limitation, any rights or
claims of materialmen or mechanics to liens on the Property), except to the extent that such expense, loss or damage arises out of any act or omission of Seller or the mere discovery of any pre-existing condition at the Property. Prior to
Buyer’s entry upon the Property as described above, Buyer shall obtain and maintain, at Buyer’s sole cost and expense, and shall deliver to Seller evidence of, commercial general liability coverage in an amount not less than $1,000,000 and
naming Seller as an “additional insured”. 
 4.2 Inspection of Documents. The right of inspection
described in Section 4.1 above shall extend to, and include, the right to examine, and Seller agrees to make available at Seller’s management office, all of Seller’s material records with respect to the Property, including, without
limitation, Seller’s tenant files (including all delinquency reports and any correspondence to or from any tenants), the plans and specifications, the engineering reports, the feasibility studies, the licenses, the warranties, the rent roll for
the Property, the Property Contracts, title documents, title insurance policies, surveys, and any information Seller may have regarding the zoning status of the Property all to the extent any such items are in Seller’s possession or control. In
furtherance of Seller’s duties hereunder, Seller shall deliver to Buyer contemporaneously with Seller’s execution of this Agreement copies of the following (all to the extent any such items are in Seller’s possession or control the
documents described below herein referred to as the “Due Diligence Documents”): 
 4.2.1 Existing building permits,
permanent certificates of occupancy or equivalent, regarding the Improvements; 
 4.2.2 The most recent existing survey of the Property;

 4.2.3 A copy of Seller’s policy of title insurance on the Property and all title exception documents that are listed therein; 

4.2.4 Warranties, Property Contracts, maintenance agreements, equipment leases, utility agreements and other agreements relating to the
operation of the Property; 

  
 5 

 4.2.5 Real estate tax bills with respect to the Property for the previous three (3) and
current tax fiscal years; 
 4.2.6 Existing reports and correspondence relating to the environmental status of the Property; 

4.2.7 Any existing engineering reports with respect to the Property; and 

4.2.8 Any other items reasonably requested by Buyer, but not including any Confidential Information. 

4.3 Termination. The term “Inspection Period,” as used herein, shall mean the period ending at 5:00
P.M. Boston, Massachusetts Time on July 8, 2014. Buyer may terminate this Agreement in its sole discretion by giving written notice of such election to Seller prior to the end of the Inspection Period, in which
event (i) the Deposit shall be returned promptly to Buyer, and (ii) except as expressly set forth herein, neither party shall have any further liability or obligation to the other hereunder. In the absence of such written notice, Buyer
shall be deemed to have waived its right to terminate this Agreement under this Section 4.3, and this Agreement shall continue in full force and effect. 

4.4 Title and Survey Matters.  

4.4.1 Buyer shall promptly at its sole cost and expense obtain a title commitment (“Title Commitment”) from the Escrow Agent
and, if the Buyer so elects, a survey or update to the existing survey (“Survey”) of the Property. At least three (3) Business Days prior to the expiration of the Inspection Period, Buyer shall give written notice to Seller of
any objections with respect thereto (“Buyer’s Title Objection Notice”), indicating in reasonable detail the nature and reasons for Buyer’s objections and including with such notice a copy of the Title Commitment and
Survey, together with copies of any documents containing matters objected to in such notice. Failure to give such notice shall constitute Buyer’s approval of all matters set forth in the Title Commitment and the Survey (exclusive of any
Monetary Liens, as defined below), which Monetary Liens Seller shall in all events be required to discharge at or prior to Closing. 
 4.4.2
Seller shall have the right, but not the obligation, to attempt to cure any objections set forth in Buyer’s Title Objection Notice. Seller shall notify Buyer within two (2) Business Days after receipt of Buyer’s Title Objection Notice
(“Seller’s Title Objection Response Period”) whether Seller agrees to attempt to cure any objections set forth in Buyer’s Title Objection Notice. Seller’s failure to respond to Buyer’s Title Objection Notice by
the end of Seller’s Title Objection Response Period shall be deemed Seller’s notice of its intent not to cure any objections. If Seller so agrees to attempt to cure any objections, then Seller shall have the right, if reasonably necessary
in order to effectuate such cure, to extend the Closing Date for up to ten (10) Business Days (“Title Cure Period”) in order to effectuate such cure, provided that such extension right and Title Cure Period shall not apply to
Seller’s cure of any Monetary Liens. 

  
 6 

 4.4.3 If Seller fails to give notice to Buyer prior to the expiration of Seller’s Title
Objection Response Period that Seller will attempt to cure all objections set forth in Buyer’s Title Objection Notice, Buyer may, within five (5) Business Days after the expiration of Seller’s Title Objection Response Period,
terminate this Agreement by written notice to Seller, in which event (i) the Deposit shall be returned promptly to Buyer, and (ii) except as expressly set forth herein, neither party shall have any further liability or obligation to the
other hereunder. If Buyer does not so terminate this Agreement within said five (5) Business Days after the expiration of Seller’s Title Objection Response Period, Buyer shall be deemed to have waived its objections set forth in
Buyer’s Title Objection Notice that Seller has not agreed in writing to attempt to cure, and to have agreed to accept title to the Property subject thereto, as Permitted Encumbrances (as defined below) without reduction in the Purchase Price.

 4.4.4 In the event Seller gives timely notice to Buyer that Seller will attempt to cure any objections set forth in Buyer’s Title
Objection Notice, and if this Agreement is not terminated pursuant to Section 4.4.3 above, Seller shall use commercially reasonable efforts to cure such objections and deliver evidence of such cure satisfactory to the Escrow Agent and Buyer
within the Title Cure Period, but in no event shall Seller be required to initiate litigation or expend more than a maximum amount of $50,000.00 in the aggregate to effectuate the cure of all such objections (excluding Monetary Liens and Voluntary
Liens, as to which such maximum amount shall not apply). If despite Seller’s commercially reasonable efforts Seller fails to cure all such matters within the Title Cure Period, Buyer’s sole right with respect thereto shall be to terminate
this Agreement within two (2) Business Days after the expiration of the Title Cure Period, in which event (i) the Deposit shall be returned promptly to Buyer; and (ii) except as expressly set forth herein, neither party shall have any
further liability or obligation to the other hereunder. If Buyer does not so terminate this Agreement, Buyer shall be deemed to have waived its objections and to have agreed to accept title to the Property subject thereto, without reduction in the
Purchase Price. 
 4.4.5 Notwithstanding the foregoing or anything to the contrary in this Agreement, Seller agrees to cure at or prior to
the Closing all Monetary Liens and Voluntary Liens at Seller’s sole cost and expense. As used herein, (i) “Monetary Liens” shall mean any security deed, mortgage, lien, security interest, judgments, or past due taxes upon
the Property created by Seller or otherwise encumbering the Property, and (ii) “Voluntary Liens” shall mean all non-monetary liens and encumbrances which Seller has voluntarily placed on the Property without Buyer’s
written consent from and after the Effective Date. A Monetary Lien shall be deemed cured by Seller if such Monetary Lien is released, satisfied or canceled of record or bonded over (to the satisfaction of Buyer in its sole discretion) at or prior to
the Closing at no additional cost to Buyer, provided, however, that as to any institutional mortgage, the lien of such mortgage shall be deemed satisfactorily released if written confirmation is received from the mortgagee stating the amount to be
delivered at the Closing to discharge such mortgage, in form and substance satisfactory to Buyer and the Escrow Agent to remove such mortgage from the list of encumbrances in Buyer’s Title Policy (as defined below). 

4.4.6 If Buyer does not terminate this Agreement pursuant to this Section 4.4, the following matters shall be deemed accepted by Buyer
and shall be referred to herein as “Permitted Encumbrances”: 
 4.4.6.1 All matters disclosed in the Title Commitment and
the Survey to which Buyer does not object or which Buyer is deemed to have accepted pursuant to the terms and conditions of this Section 4.4, other than Monetary Liens and Voluntary Liens; 

  
 7 

 4.4.6.2 Any liens for such taxes for the then current year as are not due and payable on the
Closing Date, and any liens for municipal betterments assessed after the Effective Date; and 
 4.4.6.3 The provisions of any building,
zoning, subdivision, and similar laws applicable to the Property. 
 4.5 “As Is” Sale. Except
as expressly set forth in this Agreement or in any document to be executed by Seller and delivered to Buyer at Closing, it is understood and agreed that Seller is not making, and has not at any time made and hereby specifically disclaims any
warranties or representations of any kind or character, express or implied, with respect to the Property, including, but not limited to, any warranties or representations as to habitability, merchantability or fitness for a particular purpose. 

Buyer acknowledges and agrees that upon Closing, Seller shall sell and convey to Buyer and Buyer shall accept the Property “as is,
where is, with all faults,” except to the extent expressly provided otherwise in this Agreement, including, without limitation, the representations, warranties, and covenants of Seller set forth herein or in any document to be executed by
Seller and delivered to Buyer at Closing. Buyer has not relied and will not rely on, and Seller is not liable for or bound by, any express or implied warranties, guaranties, statements, representations, or information pertaining to the Property or
relating thereto (including specifically, without limitation, any prospectus distributed with respect to the Property) made or furnished by Seller, the managers of the Property, or any real estate broker or agent representing or purporting to
represent Seller, to whomever made or given, directly or indirectly, orally or in writing, unless specifically set forth in this Agreement or in any document to be executed by Seller and delivered to Buyer at Closing. Buyer also acknowledges that
the Purchase Price reflects and takes into account that the Property is being sold “as-is”. 
 Buyer represents to Seller that
Buyer has conducted, or will conduct prior to Closing, such investigations of the Property, including, but not limited to, the physical and environmental conditions thereof, as Buyer deems necessary or desirable to satisfy itself as to the condition
of the Property and the existence or nonexistence or curative action to be taken with respect to any hazardous or toxic substances on or discharged from the Property, and will rely solely upon same and not upon any information provided by or on
behalf of Seller or its agents or employees with respect thereto, other than such representations, warranties, and covenants of Seller as are expressly set forth in this Agreement or in any document to be executed by Seller and delivered to Buyer at
Closing. Except for Buyer’s right to bring a claim by reason of or arising out of Seller’s breach of any of its representations, warranties or covenants in this Agreement or in any document to be executed by Seller and delivered to Buyer
at Closing, upon Closing, Buyer shall assume the risk that adverse matters, including, but not limited to, construction defects and adverse physical and environmental conditions, may not have been revealed by Buyer’s investigations. Except for
Buyer’s right to bring a claim by reason of or arising out of Seller’s breach of any of its representations, warranties or covenants in this Agreement or in any 

  
 8 

 
document to be executed by Seller and delivered to Buyer at Closing, upon Closing, Buyer shall be deemed to have waived, relinquished and released Seller (and Seller’s officers, directors,
shareholders, employees and agents) from and against any and all claims, demands, causes of action (including causes of action in tort), losses, damages, liabilities, costs and expenses (including reasonable attorneys’ fees) of any and every
kind or character, known or unknown, which Buyer might have asserted or alleged against Seller (and Seller’s officers, directors, shareholders, employees and agents) at any time by reason of or arising out of any latent or patent
construction defects or physical conditions, violations of any applicable laws and any and all other acts, omissions, events, circumstances or matters regarding the Property. The provisions of this paragraph shall survive Closing or any termination
of this Agreement. 
 4.6 Buyer’s Waiver and Release of Seller as to Certain Actions after Closing. Buyer
agrees that, if at any time after the Closing, any third party or any governmental agency seeks to hold Buyer responsible for the presence of, or any loss, cost or damage associated with, Hazardous Materials (as defined below) in, on, above or
beneath the Real Property or emanating therefrom, Buyer waives any rights it may have against Seller in connection therewith including, without limitation, under CERCLA (defined below), except for Buyer’s right to bring a claim by reason of or
arising out of Seller’s breach of any of its representations, warranties or covenants in this Agreement or in any document to be executed by Seller and delivered to Buyer at Closing, and Buyer agrees that except as provided above it shall not
(i) implead Seller, (ii) bring a contribution action or similar action against Seller or (iii) attempt in any way to hold Seller responsible with respect to any such matter. The provisions of this Section 4.6 shall survive the
Closing. As used herein, “Hazardous Materials” shall mean and include, but shall not be limited to, any petroleum product and all hazardous or toxic substances, wastes or substances, any substances which because of their quantitated
concentration, chemical, or active, flammable, explosive, infectious or other characteristics, constitute or may reasonably be expected to constitute or contribute to a danger or hazard to public health, safety or welfare or to the environment,
including, without limitation, any hazardous or toxic waste or substances which are included under or regulated by law, governmental rules or regulations (whether now existing or hereafter enacted or promulgated, as they may be amended from time to
time), including, without limitation, the Comprehensive Environmental Response, Compensation and Liability Act of 1980, 42 U.S.C. Section 9601 et seq. (“CERCLA”), the Federal Resource Conservation and Recovery Act, 42 U.S.C.
Section 6901 et seq., and similar state laws and regulations adopted thereunder.

be responsible for the payment of any fee, cost or expense associated with the termination of any Property Contract. 
 5.3

Seller’s current practices and continue to maintain the Property in good working order and condition and in a manner consistent with Seller’s current 

  
 10 

 
practices and, in connection with the same, Seller will not remove from the Property any Tangible Personalty without the prior written approval of Buyer, which approval, shall not be unreasonably

6.1 Casualty. If prior to the Closing any portion of the Property (i) is damaged or destroyed by fire or
other casualty, which damage is reasonably estimated to cost in excess of $2,000,000.00 to repair, then Buyer shall have the right in its sole and absolute discretion, by giving Seller written notice within ten (10) Business Days after receipt
of notice from Seller of such occurrence (with the Closing Date to be postponed, if necessary, to give both parties the benefit of the full ten (10) Business Day period) to elect to: (i) terminate this Agreement, in which case the Deposit
shall be returned promptly to Buyer and, except as expressly set forth herein, neither party shall have any further liability or obligation to the other hereunder; or (ii) close the sale contemplated herein. If Buyer does not have the right to
terminate this Agreement or having such right elects or is deemed to have elected not to terminate this Agreement, then this Agreement shall remain in full force and effect, and the purchase contemplated herein shall be effected without reduction in
the Purchase Price. In such event, Seller shall at the Closing assign, transfer and set over unto Buyer all of Seller’s right, title and interest in and to any insurance proceeds paid or payable in connection with such damage or destruction,
and Buyer shall receive a credit at Closing against the Purchase Price for the deductible amount of any such insurance. The provisions of this Section 6.1 shall survive the Closing. 

6.2 Condemnation. If prior to the Closing any portion of the Property becomes subject to a bona fide threat of
condemnation by a body having the power of eminent domain or condemnation, or sale in lieu thereof, which either (A) materially and adversely affects any portion of the Building, parking area or access driveways on the Property, or (B) in
Buyer’s reasonable judgment materially and adversely affects access to the Property, then Buyer shall have the right in its sole and absolute discretion, by giving Seller notice within ten (10) Business Days after receipt of notice from
Seller of such occurrence (with the Closing Date to be postponed, if necessary, to give both parties the benefit of the full ten (10) Business Day period) to elect to: (i) terminate this Agreement, in which case the Deposit shall be
returned promptly to Buyer and, except as expressly set forth herein, neither party shall have any further liability or 

  
 11 

 
obligation to the other hereunder; or (ii) close the sale contemplated herein. If Buyer does not have the right to terminate this Agreement or having such right elects or is deemed to have
elected not to terminate this Agreement, then this Agreement shall remain in full force and effect and the purchase contemplated herein, less any portion of the Property taken by eminent domain or condemnation, shall be effected without reduction in
the Purchase Price. In such event, Seller shall at the Closing assign, transfer and set over unto Buyer all of Seller’s right, title and interest in and to any awards paid or payable in connection with such taking. The provisions of this
Section 6.2 shall survive the Closing.

Date. If any Taxes have not been finally assessed as of the Closing Date for the current fiscal year of the taxing authority, then the same shall be adjusted at Closing based upon the most recently issued bills therefor, and shall be

  
 14 

 
readjusted when final bills are issued. If any Operating Expenses cannot conclusively be determined as of the date of Closing, then the same shall be adjusted at Closing based upon the
most recently issued bills thus far and shall be readjusted within one hundred twenty (120) days after the Closing, or if the final bills for such Operating Expenses are not available within such time period, as soon as practicable after
receipt of the final bills; provided, however, all such adjustments and reconciliations shall occur no later than six (6) months after the Closing Date. Subject to the foregoing prorations, Buyer hereby agrees to assume all
non-delinquent assessments affecting the Property, whether special or general. Buyer and Seller shall each make available to the other their books and records pertaining to Operating Expenses and Taxes for purposes of the final adjustments described
above. The provisions of this Section 9.1.1 shall survive Closing. 
 9.1.2 Charges under Property
Contracts. The unpaid monetary obligations of Seller with respect to any of the Property Contracts not being terminated as of the Closing Date shall be prorated on a per diem basis as of the date of Closing. The provisions of this
Section 9.1.2 shall survive Closing. 
 9.1.3 Utilities. Utilities, including water, sewer, electric and
gas shall be prorated based upon the last reading of meters prior to the Closing. Seller shall endeavor to obtain meter readings on the day before the Closing Date, and, if such readings are obtained, there shall be no proration of such items.
Seller shall pay at Closing the bills therefor for the period ending on the day preceding the Closing Date, and Buyer shall pay the bills therefor for the period subsequent thereto. If the utility company will not issue separate bills, Buyer will

 10. Remedies. 

10.1 Buyer Default. In the event Buyer breaches or fails to complete the purchase of the Property or to perform
its obligations under this Agreement, then, except as otherwise expressly set forth in this Agreement, Seller shall, as its sole remedy therefor, be entitled to receive the Deposit as liquidated damages (and not as a penalty) in lieu of, and as full
compensation for, all other rights or claims of Seller against Buyer by reason of such default, upon receipt of which this Agreement shall terminate and the parties shall be relieved of all further obligations and liabilities hereunder, except as
expressly set forth herein. Buyer and Seller acknowledge that the damages to Seller resulting from Buyer’s breach would be difficult, if not impossible, to ascertain with any accuracy, and that the liquidated damage amount set forth in this
Section 10.1 represents both parties’ best efforts to approximate such potential damages. Provided that Seller is not in default under this Agreement, if Seller terminates this Agreement pursuant to a right given to it hereunder and Buyer
files any lis pendens or other form of attachment against the Property), then Buyer (and any permitted assignee of Buyer’s interest hereunder) shall be liable for all loss, cost, damage, liability or expense incurred by Seller by reason of such
filing. Notwithstanding anything contained herein to the contrary, Buyer acknowledges that Buyer’s indemnification obligations which are expressly stated herein to survive the Closing or termination of this Agreement are and shall not be
limited by the amount of submission or forfeiture of the Deposit. 
 10.2 Seller Default. If Seller fails to
perform any of its obligations under this Agreement or is otherwise in breach or default of this Agreement, in each case prior to Closing, then Buyer, as its sole and exclusive remedy at law or in equity for such failure, may either:
(i) terminate this Agreement by written notice to Seller and Escrow Agent given prior to or on the Closing Date (as may be extended) whereupon Buyer shall receive a refund of the Deposit and, solely in the event of a willful default by Seller,
reimbursement from Seller for Buyer’s out-of-pocket costs and expenses (including diligence costs and reasonable attorneys’ fees) incurred in connection with this transaction up to a maximum amount of $50,000, or (ii) enforce specific
performance of Seller’s obligations under this Agreement. The provisions of this Section 10.2 shall survive termination of this Agreement. 

11. Confidentiality. This Agreement and all negotiations and related documentation will be held strictly
confidential by the parties and shall not be disclosed by Buyer or Seller, subject to Buyer’s and Seller’s ability to disclose this Agreement and such applicable information and documentation (i) to their respective officers,
directors, attorneys, investors, shareholders, accountants, agents, advisors, lenders and others who are involved in this transaction and such disclosure shall be limited to the extent such parties have reason or need to know of the transaction,
(ii) to the extent disclosure is required by law or order of a court or government entity of competent jurisdiction, and (iii) to the extent necessary in connection with the enforcement of Buyer’s or Seller’s (as applicable)
rights under this Agreement. Buyer agrees to keep confidential and not to use, other than in connection with its determination whether to proceed with the purchase of the Property in accordance with the terms and conditions of this Agreement, any of
the documents, material or information regarding the Property supplied to Buyer by Seller or by any third party at Seller’s request, including, without limitation, any environmental site assessment reports furnished to Buyer, subject to Buyers
ability to disclose such information and documentation as set forth in clauses (i), (ii) and (iii) above. In addition, no party which is a signatory to this Agreement shall issue any press release or other public

  
 16 

 
announcement regarding this transaction without first obtaining written approval from both Seller and Buyer with respect to the release or announcement and the content thereof. In the event that
the Closing does not occur in accordance with the terms of this Agreement, Buyer shall return to Seller all of the documents, material or information regarding the Property supplied to Buyer by Seller or at the request of Seller. The provisions of
this Section 11 shall survive the termination of this Agreement but shall no longer be applicable following Closing in accordance with the terms of this Agreement. Notwithstanding the foregoing, nothing contained in this Agreement or in any
other agreement between Seller and Buyer shall prohibit or limit Buyer or its affiliates from being able to disclose this Agreement or any documents or information relating thereto or in respect of the Property or this transaction to the extent
necessary under the rules and regulations of any stock exchange, governmental agency or other regulatory body, or to the extent required by any examiners, regulators or similar authorities, or in marketing materials and reports prepared for
investors in Buyer and/or its affiliates.

16.1 Authority. Buyer is a corporation duly organized, validly existing and in good standing under the laws of the
State of Delaware and has all requisite power and authority to enter into this Agreement and to perform its obligations hereunder. The execution and delivery of this Agreement by Buyer has been duly authorized. 

16.2 No Conflict. The execution and delivery of this Agreement and the consummation of the transactions
contemplated hereunder on the part of Buyer does not and will not violate any applicable law, ordinance, statute, rule, regulation, order, decree or judgment, conflict with or result in the breach of any material terms or provisions of, or
constitute a default under, or result in the creation or imposition of any lien, charge, or encumbrance upon any of the property or assets of the Buyer by reason of the terms of any contract, mortgage, lien, lease, agreement, indenture, instrument
or judgment to which Buyer is a party or which is or purports to be binding upon Buyer or which otherwise affects Buyer, which will not be discharged, assumed or released at Closing. No action by any federal, state or municipal or other governmental
department, commission, board, bureau or instrumentality is necessary to make this Agreement a valid instrument binding upon Buyer in accordance with its terms. 

16.3 OFAC. Buyer is not, and will not be, a Person with whom Seller is restricted from doing business with under
the Anti-Terrorism Laws, including persons and entities named on the Office of Foreign Asset Control Specially Designated Nationals and Blocked Persons List.

Agreement to any other individual or entity without the consent thereto by Seller, except that Buyer may assign or transfer such rights and obligations to a wholly-owned subsidiary of Buyer or to an entity controlling, controlled by or under common
control with Buyer without Seller’s consent, but with prior notice to Seller. Notwithstanding any such assignment consented to by Seller or permitted hereunder, the Buyer named in this Agreement shall remain primarily liable for the obligations
of Buyer set forth in this Agreement. No assignment or transfer by Buyer will be permitted if such assignment or transfer would, in Seller’s opinion, cause this transaction to violate any provision of applicable law. 

17.2 Governing Law; Bind and Inure. This Agreement shall be governed by the law of the Commonwealth of
Massachusetts and shall bind and inure to the benefit of the parties hereto and their respective heirs, executors, administrators, successors, assigns and personal representatives.

17.4 Time of the Essence. Time is of the essence of this Agreement. 

17.5 Headings. The headings preceding the text of the sections and subsections hereof are inserted solely for
convenience of reference and shall not constitute a part of this Agreement, nor shall they affect its meaning, construction or effect. 

17.6 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument. Each such counterpart may be delivered by facsimile or e-mail (in .pdf format) and any signatures which are so delivered by facsimile or e-mail shall be deemed
original signatures for all purposes. 
 17.7 Exhibits. All Exhibits which are referred to herein and which are
attached hereto constitute a part of this Agreement. 
 17.8 Survival. Unless otherwise expressly stated in this
Agreement, each of the warranties and representations of Seller and Buyer shall not survive the Closing and delivery of the Deed and other closing documents by Seller to Buyer, and shall be deemed to have merged therewith. The provisions of this
Section 17.8 and of Sections 17.2, 17.4, 17.5, 17.6, 17.7, 17.11, 17.13 and 17.14 shall survive Closing. 
 17.9 Use of
Proceeds to Clear Title. To enable Seller to make conveyance as herein provided, Seller may, at the time of Closing, use the Purchase Price or any portion thereof to clear the title of any or all encumbrances or interests,
provided that provision reasonably satisfactory to the Escrow Agent and Buyer’s attorney is made for prompt recording of all instruments so procured in accordance with conveyancing practice in the jurisdiction in which the
Property is located. 

  
 22 

 17.10 Submission not an Offer or Option. The submission of this
Agreement or a summary of some or all of its provisions for examination or negotiation by Buyer or Seller does not constitute an offer by Seller or Buyer to enter into an agreement to sell or purchase the Property, and neither party shall be bound
to the other with respect to any such purchase and sale until a definitive agreement satisfactory to the Buyer and Seller in their sole discretion is executed and delivered by both Seller and Buyer. 

17.11 Entire Agreement; Amendments. This Agreement and the Exhibits hereto set forth all of the promises,
covenants, agreements, conditions and undertakings between the parties hereto with respect to the subject matter hereof, and supersede all prior and contemporaneous agreements and understandings, inducements or conditions, express or implied, oral
or written, except as contained herein. This Agreement may not be changed orally but only by an agreement in writing, duly executed by or on behalf of the party or parties against whom enforcement of any waiver, change, modification, consent or
discharge is sought.

obligation of a party hereunder is other than a Business Day, or the last day for the giving of any notice required or permitted hereunder is other than a Business Day, the time for such payment, performance or delivery shall automatically be
extended to the first Business Day following such date. As used herein, “Business Day” shall mean any day other than a Saturday, Sunday or any other day on which banking institutions in the Commonwealth of Massachusetts are

Mortgagor covenants to pay when due all taxes, charges, assessments, water rates, sewer use charges and other charges which may form the basis

of these purposes or to the repayment of any amounts so paid by Mortgagee any sums paid hereunder by Mortgagor as principal, interest, taxes or otherwise. 

It shall be a breach of this Mortgage if the Mortgaged Premises is in violation in any material respect of any federal, state or local
environmental law, or lien arising therefrom, which violation is not cured, or lien removed, within any period afforded by law to cure same. 

Mortgagor hereby covenants that if there shall be any breach of the statutory condition respecting any Mortgage which is prior in right
hereto, Mortgagee hereunder shall have the right to declare all Obligations immediately due and payable. 
 Except as otherwise specifically
provided for in this Mortgage, it shall be a breach of the conditions of this Mortgage and an event permitting Mortgagee to exercise its remedies hereunder, if, without Mortgagee’s prior written consent in each instance, which consent shall not
be unreasonably withheld, conditioned or delayed: there is any sale, conveyance, or transfer of all or any portion of the Mortgaged Premises; provided, however, that Mortgagee’s consent to any sale, conveyance or transfer of the Mortgaged
Premises shall not be required if the Obligations are paid in full in connection with any such sale, conveyance or transfer. 
 Mortgagor
covenants that in the event the legal ownership of the Mortgaged Premises becomes vested in any other person than Mortgagor, Mortgagee may, without notice to Mortgagor, deal with such successor or successors in interest with reference to this
mortgage and the Obligations secured hereby in the same manner as with Mortgagor, without in any way affecting or discharging Mortgagor’s liability hereunder or the Obligations hereby secured; and no forbearance on the part of Mortgagee and no
extensions of the time for the payment, the performance of any of the Obligations of Mortgagor as set forth herein or other indulgences shall operate to release, discharge, modify, change or affect the liability of Mortgagor herein, either in whole
or in part. 
 In the event of redemption after foreclosure proceedings have been commenced, Mortgagee shall be entitled to collect all
costs, charges and expenses, including reasonable attorney’s fees, incurred up to the time of redemption. In case of a foreclosure sale Mortgagee shall be entitled to retain out of the monies arising from such sale all sums then secured by this

 
mortgage, whether then or thereafter payable, including all costs, charges, or expenses, including reasonable attorney’s fees, incurred or sustained by Mortgagee by reason of any default in
the performance or observance of any condition of this mortgage. 
 As to the Fixtures, Mortgagee shall have all the rights and remedies of
a Secured Party under the Uniform Commercial Code as now in effect in the Commonwealth of Massachusetts including, but not limited to, the option to proceed as to both the real estate and Fixtures under the law relating to foreclosure of real estate
mortgages, and such further remedies as from time to time may hereafter be provided in Massachusetts for a Secured Party, and upon the further condition that all such rights of Mortgagee under this Mortgage may be exercised together or separately.

 Included in this mortgage as part of the real estate of the Mortgaged Premises are all of the following articles now or hereafter on the
Mortgaged Premises or used therewith; portable or sectional buildings, furnaces, heaters, ranges, mantels, gas and electric light fixtures, refrigerators, refrigeration equipment, ventilating and air conditioning equipment, garbage incinerator,

or placed therein prior to the full payment and discharge of this Mortgage (“Fixtures”). 
 Mortgagor hereby grants to Mortgagee a
continuing security interest in all of the Fixtures in which a security interest may be granted under the Uniform Commercial Code as such is in effect in the Commonwealth of Massachusetts as may be amended from time to time, together with all
proceeds and products, whether now or at any time hereafter acquired to secure all Obligations. 
 Mortgagor on Mortgagee’s written
request shall promptly cause this Mortgage and Security Agreement and any required financing statements to be recorded and re-recorded, registered and re-registered, filed and re-filed at such times and places as may be required by law or reasonably
deemed advisable by Mortgagee to create, preserve or protect the priority hereof and of any lien created hereby upon the Mortgaged Premises or any part thereof; and Mortgagor shall from time to time do and cause to be done all such things as may be
required by law, including all things which may from time to time be necessary under the Uniform Commercial Code of Massachusetts fully to create, preserve and protect the priority hereof and of any lien created hereby upon said property. 

If any provision of this Mortgage or portion of such provision or the application thereof to any person or circumstance shall to any extent be
held invalid or unenforceable, the remainder of this Mortgage (or the remainder of such provision) and the application thereof to other persons or circumstances shall not be affected thereby. 

The use of the singular herein shall include the plural, and the use of the plural shall include the singular, and the use of the masculine
gender shall include the feminine and the use of the feminine shall include the masculine. 

 Any demand, notice or request by either party to the other shall be given in the manner provided
in that certain Purchase Agreement by and between Mortgagor and Mortgagee dated as of May     , 2014. 
 Notwithstanding
anything to the contrary set forth in this Mortgage, Mortgagor shall have the right at any time and from time to time to prepay in whole or in part the Obligations without any prepayment penalty or premium of any kind. At such time as the
Obligations are paid and satisfied in full, Mortgagee agrees to execute and deliver to Mortgagor, at Mortgagor’s cost, a discharge of mortgage in proper form for recording in the public land records where the Property is located. 

Time shall be of the essence of each provision of this Mortgage. 

 Signed as a sealed instrument as of this      day of

 PROMISSORY NOTE 

 

			
	$5,000,000.00	  	

 FOR VALUE RECEIVED, the undersigned, Sarepta Therapeutics, Inc., a Delaware corporation with
offices at 215 First Street, Cambridge, MA 02142 (the “Borrower”), hereby promises to pay to the order of Eisai, Inc., a Delaware corporation with an address of 4 Corporate Drive, Andover, Massachusetts (the
“Payee”), or such other address as the Payee shall designate in a written notice to the Borrower, the principal amount of Five Million Dollars ($5,000,000.00) with interest on the outstanding balance at the then applicable lowest
short-term federal rate per annum, such interest accruing from the date hereof. Two payments of $2,500,000 each, plus interest shall be due and payable on July 15, 2015 and January 15, 2016 (the “Maturity Date”). Interest
shall be prorated for any partial months. 
 The entire outstanding balance of this Note, together with all accrued but unpaid interest
thereon and all other sums due under this Note, shall be due and payable on the Maturity Date. 
 If any of the following events shall
occur: 
 1. the Borrower shall fail to pay either installment payment on or before its due date; or 

2. any default (subject to applicable notice, grace and cure periods) shall occur under the Mortgage (as defined below) or any
other document or agreement securing this Note; 
 3. bankruptcy or insolvency of the Borrower; 

then, and in every such event (an Event of Default), Payee may declare this Note and all interest thereon to be forthwith
due and payable on demand, whereupon this Note and all such interest and all such amounts shall become and be forthwith due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by
the Borrower. 
 This Note is secured by a Mortgage on a parcel of real estate located at 100 Federal Street, Andover, Massachusetts from
the Borrower, as mortgagor, to the Payee hereof, as mortgagee (the “Mortgage”). 
 Every maker, endorser and guarantor of
this Note or the obligation represented hereby waives presentment, demand, notice, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note, assents to any extension or
postponement of the time of payment or any other indulgence, to any substitution, exchange or release of collateral and to the addition or release of any other party or person primarily or secondarily liable. 

 The Borrower shall pay on demand all costs, including court costs and reasonable attorney’s
fees paid or incurred by any holder hereof in connection with the obligations evidenced by this Note or in enforcing this Note upon an Event of Default. 

The remedies of Payee as provided herein or at law or in equity shall be cumulative and concurrent, and may be pursued singly, successively,
or together at the sole discretion of Payee, and may be exercised as often as occasion therefore shall occur. The failure at any time to exercise any right or remedy shall not constitute a waiver of the right to exercise the right or remedy at any
other time. 
 As used herein, the term “Payee” shall mean the payee or endorsee of this Note who is in possession of it or the
bearer if this Note is at the time payable to bearer. 
 Notwithstanding the foregoing or any other provision of this Note to the contrary,
Borrower shall have the right to pay to the Payee the entire principal balance or any portion thereof plus all accrued and unpaid interest at any time and from time to time without penalty or prepayment. 

This Note shall be governed by, and construed in accordance with, the laws of the Commonwealth of Massachusetts. 

IN WITNESS WHEREOF, the undersigned has executed this Promissory Note as an instrument under seal, as of this     
day of             , 2014.
