Exhibit 10.3

October 27, 2015

Medbox, Inc.

600 Wilshire Blvd. Ste. 1500

Los Angeles, CA 90017

Attn: Mr. C. Douglas Mitchell

Chief Financial Officer

Ladies and Gentlemen:

Reference is hereby made to those certain 10% Convertible Debenture originally issued (1) September 25, 2014 and (2) January 30, 2015 to Redwood Management, LLC (“Redwood”) by Medbox, Inc., a Nevada Corporation (the “Company”’) each of which was assigned to Old Main Capital, LLC (the “Holder”) on June 24, 2015 and February 26, 2015, respectively (the “Debentures”).

Notwithstanding any provisions in the Debentures or that certain Securities Purchase Agreement, dated July 21, 2014, between the Company and the Redwood, as amended (the “SPA”), to the contrary, the Holder and the Company agree that the Holder shall waive its rights pursuant to Sections 6(a) of the Debentures (and any other debenture issued pursuant to the SPAs) and Section 4.10 of the SPAs with respect to any events that have occurred prior to the date hereof. As consideration for such waiver, the Company and the Holder hereby agree that for the next three (3) conversions by the Holder, the Holder and the Company hereby amend Section 4(b) of the Debentures as follows:

Conversion Price. The conversion price in effect on any Conversion Date shall be equal to the lower of (a) $0.75, subject to adjustment herein (the “Fixed Conversion Price”), or (b) 51% of the lowest VWAP for the sixty (60) consecutive Trading Days ending on the Trading Day that is immediately prior to the applicable Conversion Date (the resulting pricing being referred to herein as the “Conversion Price”). All such determinations will be appropriately adjusted for any stock dividend, stock split, stock combination, reclassification or similar transaction that proportionately decreases or increases the Common Stock during such measuring period. Nothing herein shall limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 6 hereof and the Holder shall have the right to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

The parties agree that sales of any shares of the Company’s common stock issued to the Holder upon conversion of the Debenture will be made pursuant to exemptions under the Securities Act of 1933 (the “Act”), such as Rule 144 of the Act, and not pursuant to the registration statement filed with the Securities and Exchange Commission (No. 333-203299) that became effective June 11, 2015 or any prospectus related thereto.

The parties agree that this amendment reflects the mutual agreement of the Company and the Holder. Except as set forth above, the Debenture shall not be amended or modified and shall remain in full force and effect. Other than as set forth herein, the Holder has not waived, is not waiving any Events of Default (as such term is defined in the SPAs) which may be continuing on the date hereof or any Events of Default which may occur after the date hereof.

The Holder agrees that it will convert the Debentures prior to any other debentures issued by the Company to Holder.
