Borrower shall use all of the proceeds of the funds loaned to Lender pursuant to the manner specified in the Interim Loan Agreement. The Lender would not have expended credit to Borrower without the grant by the Borrower of a security interest in favor of the Lender in the collateral described below. In order to provide security for the payment of the promissory note (the "Note"), the performance of certain terms, covenants, and conditions set forth in the Interim Loan Agreement and the various obligations represented hereby, Borrower is granting to the Lender a security interest in and to the collateral hereinafter described. The principal and interest evidenced by the Note, together with any extensions, modifications, or renewals; the performance of the covenants and agreements of Borrower contained in the Interim Loan Agreement, and the obligations of the Borrower under this Agreement are hereinafter referred to collectively as the "Obligation." AGREEMENT 1. Creation of Security Interest. In consideration of financial accommodations given, Borrower grants to Lender a security interest in and to the following described property (hereinafter the "Collateral") to wit: (a) Accounts receivable, meaning any right of the Borrower to payment for goods sold or to be sold or for services rendered or to be rendered, no matter how evidenced, including accounts, accounts receivable, contract rights, general intangibles, purchase orders, notes, drafts, acceptances and other forms of obligations and receivables; and (b) A certificate representing 250,000 shares of the common stock of Rexford, Inc. (the "Collateral Shares") which Collateral Shares represent a portion of the 10,500,000 shares of Rexford, Inc. common stock to be issued to Borrower's stockholders under the Agreement and Plan of Reorganization (the "Acquisition Agreement") between Rexford, Inc. and the Borrower. 2 If at any time the Collateral representing the Security Interest hereby granted should decline in value or become impaired or for any other reason be deemed by the Lender to be insufficient to secure the payment of all sums due and compliance with all obligations created under the Obligation, Borrower agrees, within 24 hours of demand by Lender, to furnish such additional Collateral as may be satisfactory to the Lender. Unless otherwise defined, the words used herein shall have the same meaning given them in the Illinois Uniform Commercial Code as now adopted and as hereafter amended from time to time. 2.

The entire amount loaned under the Note is due three (3) months from the date thereof. 3. Application of Payments. Unless applicable law provides otherwise, all payments received by Lender under the Note shall be applied by Lender first in payment of interest payable on the Note, next to the principal of the Note, and last to any other sums secured by this Agreement. 4. Escrow of Collateral Shares. Borrower has executed the Escrow Agreement attached to the Interim Loan Agreement as Exhibit D and incorporated herein by this reference (the "Escrow Agreement"), that provides for the escrow of the Collateral Shares until the Loan is paid in full or an event of default by Borrower as hereinafter provided. 5. Ownership of Collateral in General. The Borrower owns all the Collateral absolutely and no other person shall have any interest in the Collateral; except (a) as disclosed on the date hereof as a matter of public record in the proper place for filing notices of encumbrances on the respective kinds of property so affected; and (b) except as warranted or disclosed in the Interim Loan Agreement.

Survival of Warranties and Representations. The representations, warranties, covenants, agreements, indemnities, and undertakings of the parties in this Agreement shall not expire with, or be terminated or extinguished by, the execution and delivery of this Agreement or any document or instrument contemplated hereby, notwithstanding any investigations of the facts constituting the basis of the presentations and warranties of another party by any party hereto or anyone on behalf of any party hereto.

Severability. In the event of this Agreement or the application of any such provision to any person or circumstance shall conflict with any jurisdiction, then such conflict shall not affect any other provision of this Agreement which can be given effect without the conflicting provision and the remainder of this Agreement or the application of such provisions to persons or circumstances other than those as to which such provisions are held invalid or unenforceable, shall not be affected thereby. The invalidity or unenforceability of this Agreement or any provisions thereof in any jurisdiction shall not affect the validity or enforceability of this Agreement or of such provision in any 6 other jurisdiction. To this end, the provisions of this Agreement are declared to be severable. In the event that any law limiting the amount of interest or other charges permitted to be collected from the undersigned is interpreted so that any charge provided for in this Agreement, whether considered separately or together with other charges that are considered a party of this Agreement, violates such law, and the Borrower declared by a court having jurisdiction in the premises to be entitled to the benefit of such law, such charge is hereby reduced to the extent necessary to eliminate such violation. The amounts, if any, previously paid to the Lender in excess of the amounts payable to the Lender computed on the basis of such charges as reduced shall be applied by Lender to reduce the principal of the indebtedness secured by this Agreement. 13. Modification. This Agreement may not be supplemented, varied, or rescinded except by a writing which contains an express reference to this Agreement and which is signed by the party against whom enforcement of the supplement, variance, or rescission is asserted. 14. Governing Law. This Agreement is being executed and delivered and is intended to be performed in, and the execution, validity construction, and performance of this Agreement shall be construed and enforced in accordance with, the laws of the State of Illinois. IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first above written. LENDER: BORROWER: MARK A.
