GTX Corp. Note No. [__]

$[insert]

[insert], 2014

FOR VALUE RECEIVED, GTX Corp., a Nevada corporation, its assigns and successors (the “Company”), hereby promises to pay to the order of [insert], a [insert] (the “Holder”), in immediately available funds, the total principal sum of [insert] Dollars ($[insert]).  The principal hereof shall be due and payable on or before 5:00 p.m., Pacific Daylight Time, on December 31, 2015 (the “Maturity Date”) (unless such payment date is accelerated as provided in Section 5 hereof).  Payment of all amounts due hereunder shall be made at the address of the Holder provided for in Section 6 hereof.  

This Note is being issued pursuant to a Note and Share Purchase Agreement by and between the Company and Holder dated [insert], 2014 (the “Agreement”), and is part of a series of notes between the Company and various Holders issued or to be issued by the Company which shall not exceed $300,000 in aggregate principal amount.  The Notes shall rank equal to each other without preference or priority of any kind over one another, and all payments of principal with respect to any of the Notes (including prepayments as provided herein) shall be applied ratably and proportionately on the outstanding Notes on the basis of the principal amount of the outstanding indebtedness represented thereby.  The Holder hereof has executed an Agent Agreement appointing an agent to act on its behalf with respect to these matters.

1.

PREPAYMENT.  The Company may at any time, upon ten (10) business days written notice to Holder, prepay all or any part of the principal balance of this Note.  The advance notice, and the end of the ten (10) day period, shall be referred to herein as the “Prepayment Notice” and the “Prepayment Date,” respectively.  In the event that the Company sends a Prepayment Notice to Holder, Holder may elect prior to the Prepayment Date to convert into shares of Common Stock of the Company pursuant to Section 2 hereof, all or part of the amount of principal to be repaid by the proposed prepayment instead of receiving such prepayment.

2.

CONVERSION.  The outstanding principal due under this Note may be converted, in whole or in part, at any time or from time to time, at the option of the Holder, into common stock of the Company (“Conversion Shares”) at $0.015 per share (the “Conversion Price”).

(a)

Conversion Limitation.  Notwithstanding the foregoing, in no event shall Holder be entitled to convert any portion of the Note to the extent that, after such conversion, the sum of (1) the number of shares of Common Stock beneficially owned by the Holder, and (2) the number of shares of Common Stock issuable upon the full or partial conversion of the Note with respect to which the determination of this sentence is being made, would result in beneficial ownership by Holder of more than 4.99% of the outstanding shares of Common Stock (after taking into account the shares to be issued to Holder upon such conversion).  For purposes of the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and Rule 13d-3 promulgated thereunder.  The Holder further agrees that if the Holder transfers or assigns any of the Note to any affiliate of such Holder, such transfer or assignment shall be made subject to the transferee’s or assignee’s specific agreement to be bound by the provisions of this Section.

(b)

Adjustment of Conversion Price Upon Issuance of Stock for Less than Conversion Price.

(i)

Issuance of Shares of Common Stock.  In case after the date hereof, the Company shall issue any shares of Common Stock, except as set forth in Section 2(c), at a price per share less than the Conversion Price (as then in effect) (a “Dilutive Issuance”), then in each such event the Conversion Price shall be adjusted downward as determined by the following formula:

A     =       B      x    

   TA + C

             TA + NEW

where:

A =

the adjusted Conversion Price;

B =

the Conversion Price prior to adjustment;

TA =

the total number of shares of Common Stock outstanding on the applicable date, including all shares of Common Stock issuable upon exercise, conversion or exchange of convertible securities outstanding on such date, whether or not exercisable, convertible or exchangeable on such date (“Outstanding Common Equivalent Shares”);

C =

the number of shares of Common Stock which the aggregate purchase price received by the Company (including the maximum amount it may potentially receive) in the Dilutive Issuance, would purchase at the Conversion Price;

NEW =

the total number of new shares of Common Stock actually issued or issuable in the applicable Dilutive Issuance.

No adjustment to the Conversion Price shall be made as the result of the issuance of Common Stock if the Company receives written notice from the Holders of at least a majority in interest of the Notes, agreeing that no such adjustment shall be made as the result of the issuance of such additional shares of Common Stock.

(ii)

Issuance of Convertible Securities.  In case after the date hereof, the Company shall issue any convertible securities and the minimum price per share for which shares of Common Stock are issuable pursuant to such convertible securities shall be less than the Conversion Price in effect immediately prior to the issuance of such convertible securities, then the total maximum number of shares of Common Stock issuable upon the exercise or conversion of all of such convertible securities shall be deemed to be outstanding and to have been issued or sold for purposes of Section 2(b)(i) hereof for the minimum price per share as so determined.  

Subject to the following, no further adjustment of the number of Conversion Shares or Conversion Price shall be made upon the actual issuance of shares of Common Stock so deemed to have been issued.  Upon the expiration or termination of the exercise or conversion privileges of convertible securities for which any adjustment was made pursuant to this Section 2(b), or if the price payable upon exercise or conversion or the rate of conversion of any such convertible securities shall change at any time, then the Conversion Price shall be readjusted, and shall thereafter be such number and price as would have prevailed had the Conversion Price been originally adjusted (or had the original adjustment not been required, as the case may be) on the basis of (i) the shares of Common Stock, if any, actually issued upon the exercise or conversion of such convertible securities and (B) the consideration actually received by the Company upon such exercise or conversion plus the consideration, if any, actually received by the Company for the issuance of convertible securities. No such readjustment shall have the effect of decreasing the number of Conversion Shares or increasing the Conversion Price by an amount in excess of the amount of the adjustment initially made for the issuance of such convertible securities.

(c)

Dilutive Issuance Exceptions.  The following issuances of Common Stock shall be exempt from Section 2(b), and the issuance thereof shall not cause any adjustment to the Conversion Price:

(ii)

shares of Common Stock, options or convertible securities issued by reason of a dividend, stock split, split-up or other distribution on shares of Common Stock;

(iii)

3.

TRANSFERABILITY.  This Note shall not be transferred, pledged, hypothecated, or assigned by either party without the express written consent of the other Party.  In the event any third party acquires a controlling interest in the Company or acquires substantially all of the assets of the Company (a “Reorganization Event”), this Note will survive and become an obligation of the party that acquires such controlling interest or assets.  In the event of a Reorganization Event the Company agrees to make the party that acquires such controlling interest or assets, aware of the terms of this Section and this Note.  

4.
