 Exhibit 10.3 

PURCHASE AND SALE AGREEMENT 

THIS PURCHASE AND SALE AGREEMENT (as the same may be hereafter amended, modified, supplemented, renewed or restated from time to time, this
“Agreement”) is made and entered into as of this 10th day of February, 2016 (the “Effective Date”), by and between 20 COMMERCE LLC, a Delaware limited liability
company (“Seller”), and ALNYLAM PHARMACEUTICALS, INC., a Delaware corporation (“Purchaser”). 
 1. PURCHASE AND SALE OF
PROPERTY. 
 On the terms and conditions stated in this Agreement, Seller hereby agrees to sell to Purchaser and Purchaser hereby agrees
to purchase from Seller all of the following described property (collectively, the “Property”): 
 1.1 Land.
Seller’s fee simple interest in and to all of that certain tract of land situated in Norton, Bristol County, Massachusetts, as more particularly described on Exhibit 1.1 attached hereto and incorporated herein by reference, together with
all of Seller’s right, title and interest in and to the rights, privileges and easements appurtenant to such land (collectively, the “Land”). 

1.2 Permits. All of Seller’s right, title and interest in and to any transferable licenses, permits, registrations, use
agreements, orders, entitlements, privileges, guaranties and warranties, and governmental and all other approvals, including, without limitation, that certain Tax Increment Financing Agreement by and between the Town of Norton, Seller and Purchaser
dated November 19, 2015, relating to any or all of the Land and the Project (collectively, the “Permits”). 
 2. PURCHASE PRICE AND
DEPOSIT; OTHER PURCHASER PAYMENTS. 
 2.1 Payment. The aggregate purchase price (the “Purchase Price”) for the
Property shall be Seven Million One Hundred Thousand and No/100 Dollars ($7,100,000.00). The Purchase Price shall be payable by wire transfer of immediately available federal funds at the Closing. 

2.2 Deposit. 

2.2.1 Within one (1) business day following execution of this Agreement, Purchaser shall deposit Three Hundred Fifty-Five
Thousand and No/100 Dollars ($355,000.00) (together with any and all interest that may accrue thereon, the “Initial Deposit”) by wire transfer of immediately available federal funds, with Fidelity National Title Insurance Company
(the “Escrow Agent” or “Title Company”) to assure Purchaser’s performance hereunder. 

Pursuant to Section 6.2, the Initial Deposit shall be fully refundable to Purchaser by written notice to Seller any time
on or before the Due Diligence Deadline. 
 2.2.2 Prior to the expiration of the Due Diligence Deadline (as hereinafter
defined), Purchaser shall deposit an additional Three Hundred Fifty-Five Thousand and 

  
 14.1-1 








 
No/100 Dollars ($355,000.00) (together with any and all interest that may accrue thereon, the “Additional Deposit” and, together with the Initial Deposit, the
“Deposit”), by wire transfer of immediately available federal funds, with the Escrow Agent. Purchaser’s failure timely to deposit any amount required pursuant to this Section 2.2 (time being of the essence) shall be
deemed a default under this Agreement entitling Seller immediately and without notice to terminate this Agreement. Notwithstanding the foregoing, it is expressly understood and agreed that, in the event Purchaser terminates this Agreement before the
Due Diligence Deadline, the Deposit shall be immediately refunded to Purchaser. 
 2.2.3 Escrow Agent shall place the Deposit
in an interest-bearing escrow account at a federally-insured commercial bank reasonably acceptable to both Seller and Purchaser. The Escrow Agent shall hold the Deposit in accordance with this Agreement. At Closing, the Escrow Agent shall deliver
the Deposit to Seller and credit the Deposit against the Purchase Price in accordance with this Agreement. 
 2.2.4
Notwithstanding anything contained in this Agreement to the contrary, following the Due Diligence Deadline, the entire Deposit shall be conclusively deemed to have been earned by Seller and to be non-refundable to Purchaser in whole or in part under
any circumstances (including, without limitation, any prior or subsequent breach or default by Seller hereunder and any termination of this Agreement by Seller or Purchaser for any reason), except to the extent specifically provided in
Section 10.1 of this Agreement. Notwithstanding that the Deposit shall belong to Seller from and after the Due Diligence Deadline, Seller hereby authorizes and directs Escrow Agent to continue to hold the Deposit in escrow for
Seller’s account until the earlier to occur of (i) the Closing, or (ii) a default by Purchaser hereunder, whereupon Escrow Agent shall immediately release the entire Deposit from escrow and deliver the same to Seller. 

2.3 Site Work Costs. The parties acknowledge that, prior to Closing, Seller shall incur certain site work costs and other beneficial
costs with respect to the Land, as set forth on Exhibit 2.3 attached hereto (the “Site Work Costs”). At Closing, Purchaser shall reimburse Seller for all such Site Work Costs incurred by Seller as of the Closing Date. 

2.4 Contractor Termination Fee. The parties acknowledge that Seller currently has a contract with Polar Design Build, Inc. for
construction services on the Land. At Closing, Seller shall terminate such contract and Purchaser shall pay Nine Hundred Thousand and No/100 Dollars ($900,000.00) (the “Contractor Termination Fee”) to Seller to reimburse Seller for
the cost of such termination. 
 3. TITLE AND SURVEY. 

3.1 State of Title to be Conveyed. Title to the Property shall be conveyed to Purchaser at Closing in fee simple by Quitclaim Deed (the
“Deed”), free and clear of any and all liens, mortgages, deeds of trust, security interests and other encumbrances, except for: (i) the standard printed exclusions and exceptions from coverage contained in the ALTA form of
owner’s title policy issued by the Title Company to Purchaser at Closing and those items identified on Schedule B-II of the Policy of Title Insurance No. 27306-15-0132TN-FN (the 

  
 14.1-2 








 
“Existing Title Policy”), a copy of which Existing Title Policy is attached to Exhibit 3.1 attached hereto (except for any mortgages and mortgage related documents
noted in the Existing Title Policy, which Seller agrees to pay off with the sale proceeds at Closing); (ii) the lien of real estate taxes, water, sewer, vault and other public charges or assessments levied or assessed against the Property,
including any so-called payments in lieu of taxes, in each case which are a lien but not yet due and payable; (iii) any state of facts shown on the Survey (as hereinafter defined); (iv) the Amended and Restated First Amendment to Sewer Use
Agreement dated September 28, 2015 and recorded with the Bristol County North Registry of Deeds (the “Registry”) in Book 22581, Page 254; and (v) Declaration Regarding Cost Sharing dated October 13, 2015 and recorded
with the Registry in Book 22581, Page 290. The items referred to in clauses (i) through (v) above are hereinafter referred to, collectively, as the “Permitted Exceptions.” 

3.2 Title Policy and Survey. Purchaser hereby acknowledges receipt of: (i) a copy of the Existing Title Policy, identifying no
exceptions to title other than the Permitted Exceptions; and (ii) a survey of the Land and the Improvements titled “ALTA/ACSM Land Title Update Survey Plan of Land in Norton, MA,” by Halnon Land Surveying, Inc., dated June 6,
2015, revised August 28, 2015 (the “Survey”), identifying no exceptions to title other than the Permitted Exceptions. Without limiting the foregoing, but subject to Section 3.4, Seller shall have no liability to
Purchaser on account of any claims or defects or title or survey objections affecting the Property which are not shown on the Existing Title Policy, but existed as of the date thereof, it being understood and agreed that Purchaser’s sole remedy
shall be to proceed against the Title Company with respect to such matters. 
 3.3 Title Objections. During the Due Diligence Period,
Purchaser may review the Existing Title Policy as part of its investigations hereunder and will have the right to obtain a new title commitment from the Title Company (the “Title Commitment”) and to negotiate with the Title Company
in order to cause the Title Company to modify the Title Commitment to reflect only those exceptions to title that are acceptable to Purchaser. If Purchaser does not terminate this Agreement pursuant to Section 6.2, then the exceptions to
title disclosed in the Title Commitment as of the expiration of the Due Diligence Period, including any survey matters, will be deemed to be Permitted Exceptions. Seller will have no obligation to cure or remove any exceptions shown on the Existing
Title Policy or the Title Commitment other than any delinquent taxes or assessments and any monetary liens or any other encumbrances created by, through or under Seller. 

3.4 Gap Exceptions. In the event any matter which adversely affects title or Seller’s ability to comply with the terms of this
Agreement with respect to title first arises and/or is placed of record after the Due Diligence Deadline (a “Gap Exception”) and such exception is not a Permitted Exception, Purchaser shall notify Seller in writing (“Gap
Exception Notice”) of Purchaser’s objection to such Gap Exception on or before the earlier of (i) the third (3rd) Business Day following the date Purchaser first learns of
such Gap Exception, and (ii) the Closing Date. If for any reason Purchaser fails to deliver a timely Gap Exception Notice, any Gap Exception that could have been the subject of a proper Gap Exception Notice shall for all purposes constitute a
Permitted Exception for purposes of this Agreement. Seller shall have the right, but not the obligation, to attempt to cure any Gap Exceptions, and Seller shall notify Purchaser in writing within seven (7) Business Days of Seller’s receipt
of the Gap Exception 

  
 14.1-3 








 
Notice as to which, if any, of the Gap Exceptions Seller has elected to attempt to cure and, to the extent Seller elects to cure any such Gap Exceptions, Seller shall use commercially reasonable
efforts to cure such Gap Exceptions. If Seller fails to timely deliver notice to Purchaser that Seller has elected to attempt to cure a Gap Exception, Seller shall be conclusively deemed to have elected not to cure such Gap Exception. If Seller
elects to or is required to attempt to cure or remove any such Gap Exceptions, Purchaser’s and Seller’s respective rights and obligations, and any corresponding extensions of the Closing Date, shall be governed by the provisions of
Section 3.3 and Section 8.3. If at any time Purchaser elects to accept title to the Property subject to such Gap Exceptions, such Gap Exceptions shall be conclusively deemed to constitute “Permitted Exceptions” for
purposes of this Agreement. Notwithstanding anything contained in this Agreement to the contrary, nothing shall be deemed to impair or limit Seller’s right to challenge whether any purported Gap Exception constitutes a proper Gap Exception for
purposes of this Agreement. 
 4. PROPERTY INFORMATION. 

4.1 Property Information. Purchaser hereby acknowledges and agrees that Seller has delivered, or otherwise made available, as
appropriate, to Purchaser, for Purchaser’s review, copies of the Existing Title Policy, the Survey and the other documents and/or materials specifically listed on Exhibit 4.1 attached hereto (collectively, the “Property

expiration or termination of this Agreement for any reason whatsoever, Purchaser shall, within ten (10) days of Seller’s request, deliver to Seller at no cost or expense to Seller other than Purchaser’s actual out-of-pocket
third-party expenses incurred by Purchaser in connection with Purchaser’s investigation of the Property, any and all due diligence materials and other information or documentation obtained by, or made available to Purchaser, on its own or from
or at the request of Seller in connection with its investigation of the Property (to the extent the providers of such materials, information and documentation allow Purchaser to provide Seller with the same and to the extent Seller advises Purchaser
of Seller’s desire to obtain), and Purchaser’s obligation in such regard shall survive any such expiration or termination. Notwithstanding the foregoing, it is expressly understood and agreed that Seller shall not be required to pay
Purchaser’s actual out-of-pocket third-party expenses for materials, information and documentation that Seller advises Purchaser it does not require Purchaser to provide. Seller shall, at Purchaser’s request and at Purchaser’s sole
cost and expense, use commercially reasonable efforts to obtain a reliance letter addressed to Purchaser from the preparer of any report listed on Exhibit 4.1.

 14.1-9 








 
Agreement, has not been satisfied on or before the Closing Date, then Purchaser shall give written notice to Seller of the condition or conditions that Purchaser asserts are not satisfied. If the
conditions specified in such notice are not satisfied within ten (10) Business Days after receipt of such notice (with the Closing Date automatically being extended to accommodate such ten (10) Business Day period, then Purchaser may
terminate this Agreement by written notice to Seller and Escrow Agent, whereupon neither party shall have any further rights or obligations hereunder (other than any obligations of either party that expressly survive termination) and the Deposit

8.3.2 If any condition precedent to Seller’s obligation to close the transactions contemplated by this Agreement, as set

returned to Purchaser (unless the applicable conditions are not satisfied due to a default by Purchaser under this Agreement, in which case the Deposit shall be paid to Seller). Seller shall have the right to waive the unsatisfied condition or

unsatisfied conditions, other than any unmet or unsatisfied conditions arising out of a breach by either party of any of its representations and warranties hereunder of which the other party has no knowledge as of Closing.

 9.5.5 Post-Closing Adjustment. In the absence of error or omission, all prorations, adjustments

the delivery of the Deed. 
 9.5.6 Seller Election Regarding Prorations. Notwithstanding anything contained herein to
the contrary, at Seller’s election, any one or more of the prorations that would otherwise be made by adjustment to the Purchase Price may instead be paid by Seller out of separate funds, without adjustment to the Purchase Price. 

9.5.7 Survival. The provisions of this Section 9.5 shall survive Closing. 

10. REMEDIES AND ADDITIONAL COVENANTS. 

10.1 Seller Default. If Seller refuses or fails to consummate the transactions contemplated by this Agreement for any reason other than
Purchaser’s default or the permitted termination of this Agreement as herein expressly provided, Purchaser shall be entitled, as its sole remedy, either (a) to receive the return of the Deposit with interest, which return shall operate to
terminate this Agreement and release Seller from any and all liability hereunder, or (b) to enforce specific performance of Seller’s obligation to execute the documents required to convey the Property to Purchaser, it being understood and
agreed that the remedy of specific performance shall not be available to enforce any other obligation of Seller hereunder. Purchaser expressly waives its rights to seek damages in the event of Seller’s default hereunder. Purchaser shall be
deemed to have elected to terminate this Agreement and receive back the Deposit if Purchaser fails to file suit for specific performance against Seller in a court having jurisdiction in Suffolk County, Massachusetts, on or before thirty
(30) days following the date upon which Closing was to have occurred. In no event shall Seller or any Seller Party have any personal liability in connection with this Agreement or the transactions contemplated hereby. 

  
 14.1-14 








 The representations and warranties of Seller as contained in this Agreement shall survive for a
period of nine (9) months from and after the Closing Date. If Purchaser becomes aware of any breach and/or violation of any of Seller’s representations and warranties prior to Closing and Purchaser fails to give Seller notice thereof
and/or proceeds to Closing with such knowledge, Purchaser is deemed to have waived any such breach and/or violation. If Purchaser commences any action(s) to enforce any alleged breach and/or violation of any of the representations and/or warranties
of Seller as set forth in this Agreement of which Purchaser becomes aware after Closing, then Purchaser’s sole remedy shall be to seek recovery of its actual damages (but not special, consequential, speculative, punitive or other damages, all
of which are waived by Purchaser), provided, in no event may the amount of such damages, in the aggregate (with respect to any and all such breaches and/or violations for all of the Property) exceed Two Hundred Thousand and No/100 Dollars
($200,000.00) (the “Cap”), unless such breach or violation is due to Seller’s fraud or intentional misrepresentation. Notwithstanding the foregoing, Seller shall not have any liability for cure of Seller’s breach and/or
violation of Seller’s representations and warranties hereunder, whether before or after Closing, unless and until the aggregate amount of claims by Purchaser as a result of all breaches and violations of Seller exceeds Twenty-Five Thousand and
No/100 ($25,000.00) (the “Basket”), in which case Seller’s liability shall be limited to amounts in excess of the Basket. 

10.2 Purchaser Default. If Purchaser fails to consummate the transactions contemplated by this Agreement for any reason other than
Seller’s default or the permitted termination of this Agreement as herein expressly provided, Seller shall have the right, as its sole and exclusive remedy, to terminate this Agreement and to receive and retain the Earnest Money hereunder as
liquidated damages. Seller and Purchaser acknowledge and agree that (a) the Earnest Money is a reasonable estimate of and bears a reasonable relationship to the damages that would be suffered and costs incurred by Seller as a result of having
withdrawn the Property from sale and the failure of the Closing to occur due to a default by Purchaser under this Agreement; (b) the actual damages suffered and costs incurred by Seller as a result of such withdrawal and failure to close due to
a default by Purchaser would be extremely difficult and impractical to determine; and (c) the Earnest Money constitutes valid liquidated damages for such default by Purchaser. 

10.3 Damages. In no event shall Seller or Purchaser ever be liable under this Agreement for damages of any kind whatsoever (including,
without limitation, direct, incidental, consequential or punitive damages) for any breach or default or failure to perform by any of the same under this Agreement, except as specifically provided for herein; it being understood and agreed that
Purchaser’s and Seller’s sole and exclusive rights and remedies on account of any such breach, default or failure shall be limited as set forth in Section 10.1 and Section 10.2, respectively. 

11. BROKERAGE COMMISSION. 
 11.1
Brokers. Purchaser warrants and represents to Seller and Seller represents and warrants to Purchaser that each has dealt with no broker or other person entitled to a broker’s commission in connection with the negotiation or execution of
this Agreement or the consummation of the transaction contemplated hereby, other than Transwestern RBJ (for whose commission Seller shall be responsible pursuant to a separate agreement), and each agrees to


  
 14.1-15 








 
hold the other harmless and indemnify the other against all damages, claims, losses and liabilities, including legal fees, incurred by the other, arising out of or resulting from the failure of
its representation and warranty. Notwithstanding anything to the contrary contained in this Agreement, the indemnities set forth in this Section 11.1 shall survive the Closing or earlier termination of this Agreement. 

12. NOTICES. 
 12.1 Written Notice.
All notices, demands and requests which may be given or which are required to be given by either party to the other party under this Agreement must be in writing. 

12.2 Method of Transmittal. All notices, demands, requests or other communications required or permitted to be given hereunder must be
sent by (i) United States certified mail, postage fully prepaid, return receipt requested, (ii) hand delivery, (iii) Federal Express or a similar nationally recognized overnight courier service or (iv) e-mail with a confirmation
copy sent the same day by another method set forth in this Section. All such notices, demands, requests or other communications shall be deemed to have been given for all purposes of this Agreement upon the date of receipt or refusal, except that
whenever under this Agreement a notice is either received on a day which is not a Business Day or is required to be delivered on or before a specific day which is not a Business Day, the day of receipt or required delivery shall automatically be
extended to the next Business Day.

respect, such invalidity, illegality, or unenforceability will not affect any other provisions hereof, and this Agreement shall be construed as if such invalid, illegal, or unenforceable provision had not been contained herein; provided, however,
that the parties hereto shall endeavor in good faith to rewrite the affected provision to make it (i) valid, and (ii) consistent with the intent of the original provision.
