 Exhibit 10.4 

ESCROW AGREEMENT 
 THIS AGREEMENT is made
as of the 16th day of April, 2014 
 AMONG: 

Northern Power Systems Corp. (the “Issuer”) 

AND: 
 Equity Financial Trust Company (the
“Escrow Agent”) 
 AND: 

EACH OF THE UNDERSIGNED SECURITYHOLDERS OF THE ISSUER 

(a “Securityholder” or “you”) 

(collectively, the “Parties”) 
 This
Agreement is being entered into by the Parties under National Policy 46-201 Escrow for Initial Public Offerings (the Policy) in connection with the closing of the qualifying transaction between the Issuer and Wind Power Holdings,
Inc. (the “QT”). The Issuer is an “established issuer” (as defined in the Policy). 
 For good and valuable consideration,
the Parties agree as follows: 
  

	PART 1	ESCROW 

  

	1.1	Appointment of Escrow Agent 

 The Issuer and the Securityholders appoint the Escrow Agent to act as
escrow agent under this Agreement. The Escrow Agent accepts the appointment. 
  

	1.2	Deposit of Escrow Securities in Escrow  

  

	(1)	You are depositing the securities (escrow securities) listed opposite your name in Schedule “A” with the Escrow Agent to be held in escrow under this Agreement. You will immediately deliver or cause to
be delivered to the Escrow Agent any share certificates or other evidence of these securities which you have or which you may later receive. 

  

	(2)	If you receive any other securities (additional escrow securities): 

  

	 	(a)	as a dividend or other distribution on escrow securities; 

  

	 	(b)	on the exercise of a right of purchase, conversion or exchange attaching to escrow securities, including securities received on conversion of special warrants; 


 

	 	(c)	on a subdivision, or compulsory or automatic conversion or exchange of escrow securities; or 

  

	 	(d)	from a successor issuer in a business combination, if Part 6 of this Agreement applies, 








 you will deposit them in escrow with the Escrow Agent. You will deliver or cause to be delivered
to the Escrow Agent any share certificates or other evidence of those additional escrow securities. When this Agreement refers to escrow securities, it includes additional escrow securities. 

 

	(3)	You will immediately deliver to the Escrow Agent any replacement share certificates or other evidence of additional escrow securities issued to you. 


 

	1.3	Direction to Escrow Agent 

 The Issuer and the Securityholders direct the Escrow Agent to
hold the escrow securities in escrow until they are released from escrow under this Agreement. 
  

	PART 2	RELEASE OF ESCROW SECURITIES 

  

	2.1	Release Schedule for an Established Issuer 

  

	2.1.1	Usual case 

 If the Issuer is an established issuer (as defined
in section 3.3 of the Policy) and you have not sold any escrow securities in a permitted secondary offering, your escrow securities will be released as follows: 
  

			
	 On the date the Issuer’s securities are listed on a

Canadian exchange (the listing date)
	 	1/4 of your escrow securities
	6 months after the listing date	 	1/3 of your remaining escrow securities
	12 months after the listing date	 	1/2 of your remaining escrow securities
	18 months after the listing date	 	your remaining escrow securities

  

	*	In the simplest case, where there are no changes to the escrow securities initially deposited and no additional escrow securities, then the release schedule outlined above results in the escrow securities being released
in equal tranches of 25%. 

  

	2.1.2	Alternate meaning of “listing date” 

 If the Issuer is an
established issuer, an alternate meaning for listing date is the date the Issuer completes its QT if the Issuer’s securities are listed on a Canadian exchange immediately before its QT. 

 

	2.1.3	If there is a permitted secondary offering 

 [intentionally
deleted] 
  

	2.1.4	Additional escrow securities 

 If you acquire additional escrow
securities, those securities will be added to the securities already in escrow, to increase the number of remaining escrow securities. After that, all of the escrow securities will be released in accordance with the applicable release schedule in
the table above. 
  

	2.2	Delivery of Share Certificates for Escrow Securities  

 The Escrow Agent will send to each
Securityholder any share certificates or other evidence of that Securityholder’s escrow securities in the possession of the Escrow Agent released from escrow as soon as reasonably practicable after the release. 

  
 2 









	2.3	Replacement Certificates  

 If, on the date a Securityholder’s escrow securities are
to be released, the Escrow Agent holds a share certificate or other evidence representing more escrow securities than are to be released, the Escrow Agent will deliver the share certificate or other evidence to the Issuer or its transfer agent and
request replacement share certificates or other evidence. The Issuer will cause replacement share certificates or other evidence to be prepared and delivered to the Escrow Agent. After the Escrow Agent receives the replacement share certificates or
other evidence, the Escrow Agent will send to the Securityholder or at the Securityholder’s direction, the replacement share certificate or other evidence of the escrow securities released. The Escrow Agent and Issuer will act as soon as
reasonably practicable. 
  

	2.4	Release upon Death 

  

	(1)	If a Securityholder dies, the Securityholder’s escrow securities will be released from escrow. The Escrow Agent will deliver any share certificates or other evidence of the escrow securities in the possession of
the Escrow Agent to the Securityholder’s legal representative. 

  

	(2)	Prior to delivery the Escrow Agent must receive: 

  

	 	(a)	a certified copy of the death certificate; and 

  

	 	(b)	any evidence of the legal representative’s status that the Escrow Agent may reasonably require. 

  

	PART 3	EARLY RELEASE ON CHANGE OF ISSUER STATUS 

 [intentionally deleted] 

 

	PART 4	DEALING WITH ESCROW SECURITIES 

  

	4.1	Restriction on Transfer, etc. 

 Unless it is expressly permitted in this Agreement, you will not sell,
transfer, assign, mortgage, enter into a derivative transaction concerning, or otherwise deal in any way with your escrow securities or any related share certificates or other evidence of the escrow securities. If a Securityholder is a private
company controlled by one or more principals (as defined in section 3.5 of the Policy) of the Issuer, the Securityholder may not participate in a transaction that results in a change of its control or a change in the economic exposure of the
principals to the risks of holding escrow securities. 
  

	4.2	Pledge, Mortgage or Charge as Collateral for a Loan 

 You may pledge, mortgage or charge
your escrow securities to a financial institution as collateral for a loan, provided that no escrow securities or any share certificates or other evidence of escrow securities will be transferred or delivered by the Escrow Agent to the financial
institution for this purpose. The loan agreement must provide that the escrow securities will remain in escrow if the lender realizes on the escrow securities to satisfy the loan. 

 

	4.3	Voting of Escrow Securities 

 You may exercise any voting rights attached to your escrow
securities. 
  

	4.4	Dividends on Escrow Securities 

 You may receive a dividend or other distribution on your
escrow securities, and elect the manner of payment from the standard options offered by the Issuer. If the Escrow Agent receives a dividend or other distribution on your escrow securities, other than additional escrow securities, the Escrow Agent
will pay the dividend or other distribution to you on receipt.
