SEVENTH
AMENDMENT

TO

LOAN AND SECURITY AGREEMENT


 


This
Seventh Amendment to Loan and Security Agreement (the “Amendment”) is made and entered into as of April
23, 2015, by and between SQUARE 1 BANK (“Bank”) and GRIDSENSE INC. (“Borrower”).


 


RECITALS


 


Borrower
and Bank are parties to that certain Loan and Security Agreement dated as of November 2, 2012 (as amended from time to time, the
“Agreement”). The parties desire to amend the Agreement in accordance with the terms of this Amendment.


 


NOW,
THEREFORE, the parties agree as follows:


 


	1)	Section
    8.9 of the Agreement provides that an Event of Default shall occur under the Agreement if any guarantor fails to perform any
    obligation under any guaranty. Bank has determined that Acorn Energy, Inc. has not maintained the covenants set forth in Section
    9.3 of the Acorn Guaranty, which requires that Acorn Energy, Inc. maintain either (i) Acorn Energy’s cash (excluding
    Acorn Energy’s cash on the balance sheet of USSI, OmniMetrix, DSIT and Borrower) of at least $5,000,000, measured on
    a quarterly basis as set forth in the Acorn Energy’s reports on Form 10-Q filed with the Securities and Exchange Commission,
    or (ii) a Current Ratio of at least 1.50 to 1.00, measured on a quarterly basis as set forth in Acorn Energy’s
    reports on Form 10-Q filed with the Securities and Exchange Commission. Acorn Energy, Inc. failed to maintain each of the
    covenants set forth in Section 9.3 of the Acorn Guaranty, for the quarterly reporting period ending December 31, 2014. The
    failure to maintain such covenants constitutes the failure to perform its obligations under the Acorn Guaranty, and therefore
    resulted in an Event of Default under Section 8.9 of the Agreement (the “Existing Loan Agreement Event of Default”)
    and under Section 8(b) of that certain Financing Agreement (the “Financing Agreement”) between Borrower and Bank
    dated as of July 16, 2014 (the “Existing Finance Agreement Default”). Bank hereby waives the Existing Loan Agreement
    Event of Default and the Existing Finance Agreement Default. Bank sent a letter to Borrower dated April 2, 2015 related to
    the Existing Loan Agreement Event of Default and the Existing Finance Agreement Default (the “April Default Letter”).
    Bank hereby agrees that, notwithstanding anything provided in the April Default Letter, (a) the rate of interest applicable
    from and after and during the continuance of an Event of Default shall no longer be effective, (b) the Obligations shall not
    be considered immediately due and payable (but shall be due and payable in accordance with the terms and conditions of the
    Agreement (as amended by this Amendment) and the Finance Agreement, as applicable, and (c) Borrower shall not be required
    to immediately remit collections from accounts receivable to repay Borrower’s obligations under the Loan Agreement or
    the Financing Agreement (provided that collections from accounts receivable shall be handled in accordance with the terms
    of the Finance Agreement and the Agreement, as amended by this Amendment, as applicable).
	 	 
	2)	Section
    2.1(b) of the Agreement is hereby amended and restated, as follows:

(b)Advances
Under Revolving Line.


 


(i)Amount.
Subject to and upon the terms and conditions of this Agreement (1) Borrower may request Advances in an aggregate outstanding principal
amount not to exceed the Revolving Line, less any amounts outstanding under the Ancillary Services Sublimit, and (2) amounts borrowed
pursuant to this Section 2.1(b) (excluding, following the Term-Out Date, the Term-Out Principal Amount) may be repaid and reborrowed
at any time prior to the Revolving Maturity Date, at which time all Advances under this Section 2.1(b) (excluding the Term-Out
Principal Amount which shall be due and payable in accordance with Section 2.1(b)(v) below) shall be immediately due and payable.
Borrower may prepay any Advances without penalty or premium.


 


(ii)Form
of Request. Whenever Borrower desires an Advance, Borrower will notify Bank by facsimile transmission, telephone or email
no later than 3:30 p.m. Eastern time (2:30 p.m. Eastern time for wire transfers), on the Business Day that the Advance is to be
made. Each such notification shall be promptly confirmed by a Loan Advance/Paydown Request Form in substantially the form of Exhibit
C. Bank is authorized to make Advances under this Agreement, based upon instructions received from an Authorized Officer, or without
instructions if in Bank’s discretion such Advances are necessary to meet Obligations which have become due and remain unpaid.
Bank shall be entitled to rely on any telephonic or email notice given by a person whom Bank reasonably believes to be an Authorized
Officer or a designee thereof, and Borrower shall indemnify and hold Bank harmless for any damages, loss, costs and expenses suffered
by Bank as a result of such reliance. Bank will credit the amount of Advances made under this Section 2.1(b) to Borrower’s
deposit account.


 


(iii)Ancillary
Services Sublimit. Subject to the availability under the Revolving Line, at any time and from time to time from the date hereof
through the Business Day immediately prior to the Revolving Maturity Date, Borrower may request the provision of Ancillary Services
from Bank. The aggregate limit of the Ancillary Services shall not exceed the Ancillary Services Sublimit, provided that availability
under the Revolving Line shall be reduced by the aggregate limits of (i) corporate credit card services provided to Borrower,
(ii) the total amount of any Automated Clearing House processing reserves, (iii) the applicable Foreign Exchange Reserve Percentage,
and (iv) any other reserves taken by Bank in connection with other treasury management services requested by Borrower and approved
by Bank. In addition, Bank may, in its sole discretion, charge as Advances any amounts for which Bank becomes liable to third
parties in connection with the provision of the Ancillary Services. The terms and conditions (including repayment and fees) of
such Ancillary Services shall be subject to the terms and conditions of the Bank’s standard forms of application and agreement
for the applicable Ancillary Services, which Borrower hereby agrees to execute.


 


(iv)Collateralization
of Obligations Extending Beyond Maturity. If Borrower has not secured to Bank’s satisfaction its obligations with
respect to any Ancillary Services by the Revolving Maturity Date, then, effective as of such date, the balance in any deposit
accounts held by Bank and the certificates of deposit or time deposit accounts issued by Bank in Borrower’s name (and
any interest paid thereon or proceeds thereof, including any amounts payable upon the maturity or liquidation of such
certificates or accounts), shall automatically secure such obligations to the extent of the then continuing or outstanding
Ancillary Services. Borrower authorizes Bank to hold such balances in pledge and to decline to honor any drafts thereon or
any requests by Borrower or any other Person to pay or otherwise transfer any part of such balances for so long as the
applicable Ancillary Services are outstanding or continue.

September 1, 2015 (the “Term-Out Date”) and continuing on the first day of each month thereafter until May 1, 2016.

Agreement, in form and substance satisfactory to Bank, in order to grant Bank a valid security interest in all such additional
cash collateral maintained in such account.

    8.2(a) of the Agreement is hereby amended and restated, as follows:

If Borrower fails to perform any obligation under Sections 6.2 (financial reporting), 6.4 (taxes), 6.5 (insurance), 6.6 (primary
accounts), 6.7 (financial covenants), 6.11 (additional cash security for obligations under the Acorn Guaranty), or violates any
