Reference is made to that certain Credit Agreement, dated as of January 14, 2016 (as amended or otherwise modified, the “Credit Agreement”), among Rexford Industrial Realty, L.P., a Maryland limited partnership (“Borrower”), Rexford Industrial Realty, Inc., a Maryland corporation (“Parent”), PNC Bank, National Association, as Administrative Agent, and each lender from time to time party thereto. Capitalized terms used and not defined herein shall have the meaning ascribed to such terms in the Credit Agreement.

Pursuant to Section 2.12 of the Credit Agreement, Borrower, Parent, Administrative Agent, and the Lenders party hereto agree to make additional Loans to Borrower in the aggregate amount of up to $100,000,000, which additional Loans may be requested by Borrower and made by each Lender party hereto during the period from the date hereof to the earlier of (a) May 16, 2016 and (b) the date on which Lenders make any such additional Loans to Borrower (the “Increase Availability Period”).

Each Lender party hereto hereby agrees to make additional Loans to Borrower under the Credit Agreement during the Increase Availability Period in an amount not to exceed the amount of Maximum Additional Loans for such Lender set forth on Schedule 1 attached hereto, subject to the following conditions:

(a)Borrower shall not make more than one request for any additional Loans and such request shall be in the minimum amount of $25,000,000;

(b)If Borrower shall request additional Loans in an amount less than the aggregate amount of Maximum Additional Loans set forth on Schedule 1 attached hereto, then Lenders shall make such additional Loans pro rata based upon the amount of such Lender’s Maximum Additional Loans set forth on Schedule 1 attached hereto;

(c)The representations and warranties of Borrower and each other Loan Party contained in Article VII of the Credit Agreement or any other Loan Document, or which are contained in any document furnished at any time under or in connection with the Loan Documents, shall be true and correct in all material respects (without duplication of any materiality qualifiers therein) on and as of the date of such additional Loans, except to the extent that such representations and warranties specifically refer to an earlier date, in which case they shall be true and correct in all material respects (without duplication of any materiality qualifiers therein) as of such earlier date, and except that the representations and warranties contained in subsections (a) and (b) of Section 7.05 of the Credit Agreement shall be deemed to refer to the most recent statements furnished pursuant to clauses (a) and (b), respectively, of Section 8.01 of the Credit Agreement;

(d)No Default shall exist, or would result from such additional Loans or from the application of the proceeds thereof; and

(e)Administrative Agent shall have received a Loan Notice in accordance with the requirements of the Credit Agreement.

The obligations of Lenders to make additional Loans hereunder shall terminate upon the expiration of the Increase Availability Period.

During the Increase Availability Period, Borrower shall pay to Administrative Agent, for the account of each Lender, an unused fee equal to 0.20% times the Maximum Additional Loans for such Lender set forth on Schedule 1 attached hereto. Such unused fee shall be due and payable on the last day of the Increase Availability Period.

Schedule 2.01 of the Credit Agreement is hereby replaced with Schedule 1 attached hereto. If Borrower requests additional Loans in an aggregate amount less than $100,000,000, then Schedule 1 attached hereto shall be updated to reflect such lesser amount of additional Loans and such updated Schedule 1 shall replace Schedule 2.01 of the Credit Agreement.

The Loan Documents are ratified and affirmed by each of Borrower and Parent and shall remain in full force and effect.

This Increase Certificate shall constitute one of the Loan Documents.

IN WITNESS WHEREOF, each of the undersigned has executed this consent as of the date first written above.

To induce the Lenders to enter into this Increase Certificate, the undersigned hereby (a) consent and agree to its execution and delivery and the terms and conditions thereof, (b) agree that this document in no way releases, diminishes, impairs, reduces, or otherwise adversely affects any guaranties, assurances, or other obligations or undertakings of any of the undersigned under any Loan Documents, and (c) waive notice of acceptance of this Increase Certificate, which binds each of the undersigned and their respective successors and permitted assigns and inures to the benefit of Administrative Agent and Lenders and their respective successors and permitted assigns.
