(the “Agreement”), relating to certain real property located in the City of Portland, Cumberland County, Maine;

WHEREAS,

6.Contingency Period.
Subject to Section 7 and 8 of this Reinstatement and First Amendment, Buyer hereby waives all Contingencies under Section 4 of
the Agreement. Notwithstanding the foregoing, Buyer shall continue to have the right to perform due diligence on the Property,
including, without limitation entry of Buyer and its agents onto the Property in order to inspect the Property in furtherance of
obtaining a property condition report.

 

		7.	Tenant Estoppel Certificates.

 

On or before one
(1) day prior to Closing, Buyer shall have received estoppel certificates substantially in the form attached to the Agreement as
Exhibit C (the “Tenant Estoppel”), executed by each tenant under each of the Leases with respect to the status
of such Lease, rent payments, tenant improvements, lease defaults and other matters relating to such Lease, and disclosing no defaults,
disputes or other matters objectionable to Buyer in its sole and absolute discretion. Each such estoppel certificate shall, among
other things, expressly identify (a) the “Purchaser” as “Plymouth Industrial REIT, Inc.” and (b) the “Lender”
as "U.S. Bank, National Association, in its capacity as Collateral Agent for the benefit of the Lenders pursuant to a Collateral
Agency Agreement, together with its successors and/or assigns in such capacity as their interests may appear".

If Seller is unable
to obtain and deliver sufficient tenant estoppel certificates as required under this Section 7 of this Reinstatement and First
Amendment or if the estoppel certificates received contain material information or omissions unacceptable to Buyer then Seller
will not be in default by reason thereof, and Buyer may, by written notice given to Seller on or before the Closing, either (a)
elect to terminate this Agreement and receive a refund of the Deposit or (b) waive the tenant estoppel requirements. If Buyer so
elects to terminate this Agreement and receives a refund of the Deposit, neither party shall have any further rights or obligations
hereunder except for the provisions of the Agreement that expressly survive termination. If no such termination notice is delivered
by Buyer on or before Closing, then Buyer shall be deemed to have waived the tenant estoppel requirements.

8.SNDAs. Seller
shall deliver to each Tenant a Subordination, Non-Disturbance and Attornment Agreement ("SNDA") in the form requested
by Buyer and shall use commercially reasonable efforts to cause each Tenant to execute such SNDA and to deliver an originally-executed
SNDA in recordable form to Buyer. Seller shall promptly deliver any executed SNDA to Buyer and any comments to any SNDA to Buyer;
however, Seller shall not be responsible for negotiating or revising any SNDA or otherwise incurring any costs in connection with
such SNDAs. The failure of Seller to obtain any such SNDA shall not be a breach or default hereunder. If Seller is unable to deliver
SNDAs from tenants occupying not less than 100% of the square feet in the Improvements leased to tenants, then Buyer's sole remedies
and recourses shall be limited to either (a) waiving the requirement for the SNDA(s) in question and proceeding to Closing without
reduction of the Purchase Price or (b) terminating the Agreement by notification to Seller on or prior to the Closing Date and
receiving a return of the Deposit. In the event that Buyer elects to terminate the Agreement pursuant to the immediately preceding
sentence, the Deposit shall immediately be returned to Buyer and neither party shall have any further rights or obligations under
the Agreement except for the provisions of the Agreement that expressly survive termination.

 

    	-3-

    	 

    

 

9.Ratification;
Conflicts. The Agreement, as reinstated and amended by this Reinstatement and First Amendment, constitutes and contains the
sole and entire agreement of the parties hereto with respect to the subject matter hereof and no prior or contemporaneous oral
or written representations or agreements between the parties and relating to the subject matter hereof shall have any legal effect.
Except as reinstated and expressly modified in this Reinstatement and First Amendment, the Agreement remains unamended and in full
force and effect. In the event of a conflict between any provision of this Reinstatement and First Amendment and any provision
of the Agreement, the conflicting provision in this Reinstatement and First Amendment shall govern and control.

 

10.Successors.
This Reinstatement and First Amendment shall be binding upon and inure to the benefit of the parties hereto and their respective
successors, successors-in-title, representatives and assigns.

(a) (i) Cash Flow Sweep Mandatory Repayment. In the event that the Adjusted Consolidated Free Cash Flow for any Fiscal Year is
greater than $100,000, then the Company shall use 50% of such Adjusted Consolidated Free Cash Flow for such Fiscal Year to repay Borrowings under the Facility, plus accrued and unpaid interest thereon through the Mandatory Cash Flow Sweep Repayment
Date, said Adjusted Consolidated Free Cash Flow to be applied first to accrued but unpaid interest, then to principal, in each case ratably among outstanding Borrowings; provided that in the event that the Adjusted Consolidated Free Cash Flow for
any such Fiscal Year is greater than $50,000,000, then the Company shall use 75% of such Adjusted Consolidated Free Cash Flow for such Fiscal Year to repay the Facility, plus accrued and unpaid interest thereon through the Mandatory Cash Flow Sweep
Repayment Date (such repayment, the “Cash Flow Sweep Mandatory Repayment”). The amount of Adjusted Consolidated Free Cash Flow to be used to repay the Facility pursuant to this Section 4(a)(i) is referred to herein as the

Year shall be payable on the applicable Mandatory Cash Flow Sweep Repayment Date only to the extent that such Cash Flow Sweep Mandatory Repayment, if deducted from the calculation of the Cash Flow Sweep Pro Forma Cash Balance as of the end of such
Fiscal Year would not cause such Cash Flow Sweep Pro Forma Cash Balance to be less than $10 million (or $15 million following the Fiscal Year in which the Indebtedness Repayment Condition has been satisfied but in no event prior to October 1,
2015).

and the Company shall be obligated to mandatorily repay the Facility (or portion thereof) on each Mandatory Cash Flow Sweep Repayment Date occurring thereafter (until all Unpaid EACFCF shall have been paid in full) but only to the extent that such
repayment, if deducted from the calculation of the Cash Flow Sweep Pro Forma Cash Balance as of the end of the applicable Fiscal Year (and after giving effect to any Cash Flow Sweep Mandatory Repayment payable pursuant to Section 4(a)(i) on
such Mandatory Cash Flow Sweep Repayment Date) would not cause such Cash Flow Sweep Pro Forma Cash Balance to be less than $10 million (or $15 million following the Fiscal Year in which the Indebtedness Repayment Condition has been satisfied but in
no event prior to October 1, 2015) (such repayment, an “Unpaid EACFCF Mandatory Repayment”).

thereon, including outstanding Loans under Section 3(c) hereof, (C) third, if, after giving effect to clause (B) in this Section 4(b), the amount outstanding under this Agreement has been reduced to zero and there are still

the amount of such Borrowing is reduced to zero.

becomes due under the Royalty Agreement and is payable in cash in accordance with the terms of the Royalty Agreement and (B) the Royalty rate has been reduced to five percent (5%) in accordance with Section 2.1 and 2.2 of the Royalty

Royalty that has become due and payable pursuant to the Royalty Agreement (such prepayment, a “Cash Royalty Mandatory Prepayment”), solely to the extent that the cash used for such Cash Royalty Mandatory Prepayment, if deducted from
the calculation of the Cash Royalty Pro Forma Cash Balance as of the end of such Fiscal Year or Fiscal Quarter, as applicable, would not cause such Cash Royalty Pro Forma Cash Balance to be less than $10 million (or $15 million following the Fiscal
