 MEDIUM-TERM NOTE, SERIES K 

Due Nine Months or More From Date of Issue 

Principal at Risk Securities Linked to the Lowest Performing of the 

Common Stock of Celgene Corporation and the Common Stock of 

Gilead Sciences, Inc. due December 16, 2024 

WELLS FARGO & COMPANY, a corporation duly organized and existing under the laws of the State of Delaware (hereinafter
called the “Company,” which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or registered assigns, an amount equal to the
Redemption Amount (as defined below) on the Stated Maturity Date (as defined below), unless this Security is automatically called prior to the Stated Maturity Date as provided below under “Automatic Call,” and to pay Contingent Coupon
Payments (as defined below) on the Face Amount of this Security to the extent provided herein on the Contingent Coupon Payment Dates specified herein at the Contingent Coupon Rate (as defined below) until the earlier of the Stated Maturity Date and
the Call Settlement Date (as defined below), if any. The “Initial Stated Maturity Date” shall be December 16, 2024. If the Final Calculation Day (as defined below) is not postponed, the Initial Stated Maturity Date will be the
“Stated Maturity Date.” If the Final Calculation Day is postponed, the “Stated Maturity Date” shall be the later of (i) the Initial Stated Maturity Date and (ii) the third Business Day (as defined below)
after the last Final Calculation Day as postponed. 
 “Face Amount” shall mean, when used with respect to
this Security, the amount set forth on the face of this Security as its “Face Amount.” 
 Automatic Call 

If the Stock Closing Price (as defined below) of the Lowest Performing Underlying Stock (as defined below) on any of the
quarterly Calculation Days (as defined below) from December 
  

 
2018 to September 2024, inclusive, is greater than or equal to its Starting Price (as defined below), this Security will be automatically called by the Company, and on the related Call Settlement
Date the Holder hereof will receive the Call Price (as defined below) plus a final Contingent Coupon Payment. Unless the Company defaults in the payment of the Call Price plus the final Contingent Coupon Payment, this Security will cease to be
outstanding on such Call Settlement Date, no additional Contingent Coupon Payments will be payable on this Security and the Holder hereof will have no further rights under this Security after such Call Settlement Date. The Holder hereof will not
receive any notice from the Company in the event this Security is automatically called pursuant to the terms hereof. The “Call Price” is equal to the Face Amount of this Security. The “Call Settlement Date” for a
Calculation Day shall be three Business Days after such Calculation Day, as such Calculation Day may be postponed as provided herein. If a Calculation Day is postponed with respect to one or both Underlying Stocks, the related Call Settlement Date
will be three Business Days after the last Calculation Day as postponed. 
 Payment of Contingent Coupon Payments, the Redemption Amount and the Call
Price 
 On each quarterly Contingent Coupon Payment Date, the Company shall pay a Contingent Coupon Payment if, and
only if, the Stock Closing Price of the Lowest Performing Underlying Stock on the related Calculation Day is greater than or equal to its Threshold Price (as defined below). A “Contingent Coupon Payment,” if payable as provided
herein, shall be equal to the product of (i) the Face Amount of this Security, (ii) the Contingent Coupon Rate, and (iii) 90/360. The “Contingent Coupon Payment Dates” shall be the third Business Day following each
Calculation Day, as each such Calculation Day may be postponed as herein provided, provided that the Contingent Coupon Payment Date with respect to the Final Calculation Day will be the Stated Maturity Date. If a Calculation Day is postponed with
respect to one or both Underlying Stocks, the related Contingent Coupon Payment Date will be three Business Days after the last Calculation Day as postponed. The “Contingent Coupon Rate” is 9.00% per annum. Any Contingent Coupon
Payments will be rounded to the nearest cent, with one-half cent rounded upward. 

Any Contingent Coupon Payment so payable, and punctually paid or duly provided for, on any Contingent Coupon Payment Date
will, as provided in the Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such Contingent Coupon Payment next preceding such
Contingent Coupon Payment Date. The Regular Record Date for a Contingent Coupon Payment Date shall be the date one Business Day prior to such Contingent Coupon Payment Date. 

Any Contingent Coupon Payment not punctually paid or duly provided for will forthwith cease to be payable to the Holder on
such Regular Record Date and may either be paid to the Person in whose name this Security (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed
by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. 

  
 2 

 Payment of any Contingent Coupon Payment on this Security will be made in
immediately available funds at the office or agency of the Company maintained for that purpose in the City of Minneapolis, Minnesota; provided, however, that, at the option of the Company, payment of any Contingent Coupon Payment may be paid by
check mailed to the Person entitled thereto at such Person’s last address as it appears in the Security Register or by wire transfer to such account as may have been designated by such Person. Payments of any Contingent Coupon Payment and the
Redemption Amount or the Call Price, as applicable, on this Security at Maturity will be made against presentation of this Security at the office or agency of the Company maintained for that purpose in the City of Minneapolis, Minnesota and at any
other office or agency maintained by the Company for such purpose. Notwithstanding the foregoing, for so long as this Security is a Global Security registered in the name of the Depositary, any payments on this Security will be made to the
Depositary by wire transfer of immediately available funds. 
 Payment of the Redemption Amount or the Call Price, as
applicable, and any Contingent Coupon Payments on this Security will be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

Definitions Relating to Redemption Amount, the Call Price and Contingent Coupon Payments 

If this Security is not automatically called prior to the Stated Maturity Date as provided above under “Automatic
Call,” the “Redemption Amount” of this Security will equal: 
  

	 	•	 	 if the Ending Price of the Lowest Performing Underlying Stock on the Final Calculation Day (as defined below)
is greater than or equal to its Threshold Price: the Face Amount; or 

  

	 	•	 	 if the Ending Price of the Lowest Performing Underlying Stock on the Final Calculation Day is less than its
Threshold Price: 

  

																											
		 		 		 		 		 		 		 		 		 		 		 		 		 	
		 		 		 		 	 	 	Face Amount	 	  x        	 	Performance Factor of the Lowest Performing	 	 	 		 		 		 		 	
		 		 		 		 	 	 	 	 	 Underlying Stock on the Final Calculation

Day
	 	 	 		 		 		 		 	

 All calculations with respect to the Redemption Amount will be rounded to the nearest one hundred-thousandth,
with five one-millionths rounded upward (e.g., 0.000005 would be rounded to 0.00001); and the Redemption Amount will be rounded to the nearest cent, with one-half cent
rounded upward. 
 “Underlying Stock” shall mean each of the common stock of Celgene Corporation and the
common stock of Gilead Sciences, Inc. 
 The “Pricing Date” shall mean December 11, 2017. 

  
 3 

 The “Lowest Performing Underlying Stock” for any
Calculation Day will be the Underlying Stock with the lowest Performance Factor on that Calculation Day (as such Calculation Day may be postponed for one or both Underlying Stocks). 

The “Performance Factor” with respect to an Underlying Stock on any Calculation Day is its Stock Closing
Price on such Calculation Day divided by its Starting Price (expressed as a percentage). 
 The “Starting
Price” with respect to the common stock of Celgene Corporation is $108.00, its Stock Closing Price on the Pricing Date; and with respect to the common stock of Gilead Sciences, Inc. is $75.88, its Stock Closing Price on the Pricing Date.

 The “Ending Price” of an Underlying Stock will be its Stock Closing Price on the Final Calculation Day.

 The “Threshold Price” with respect to the common stock of Celgene Corporation is $59.40, which is equal
to 55% of its Starting Price; and with respect to the common stock of Gilead Sciences, Inc. is $41.734, which is equal to 55% of its Starting Price. 

The “Stock Closing Price” with respect to each Underlying Stock on a Calculation Day, means the product of
the Closing Price of such Underlying Stock and the Adjustment Factor for such Underlying Stock, each on such Calculation Day. 

The “Adjustment Factor” for each Underlying Stock is initially 1.0. The Adjustment Factor for each Underlying
Stock will remain constant for the term of this Security, subject to adjustment for certain corporate events relating to the applicable Underlying Stock Issuer as set forth below under “—Adjustment Events.” 

“Underlying Stock Issuer” shall mean the issuer of each Underlying Stock. 

“Business Day” shall mean a day, other than a Saturday or Sunday, that is neither a legal holiday nor a day
on which banking institutions are authorized or required by law or regulation to close in New York, New York. 
 The
“Calculation Days” shall be the 11th day of each March, June, September and December, commencing March 2018 and ending September 2024, and the Final Calculation Day. If any such
day is not a Trading Day with respect to either Underlying Stock, that Calculation Day for each Underlying Stock will be postponed to the next succeeding day that is a Trading Day with respect to each Underlying Stock. A Calculation Day for an
Underlying Stock is also subject to postponement due to the occurrence of a Market Disruption Event (as defined below) with respect to such Underlying Stock on such Calculation Day. The “Final Calculation Day” is December 11,
2024. If a Market Disruption Event occurs or is continuing with respect to an Underlying Stock on any Calculation Day, then such Calculation Day for such Underlying Stock will be postponed to the first succeeding Trading Day for such Underlying
Stock on which a Market Disruption Event for such Underlying Stock has not occurred and is not continuing; however, if such first succeeding Trading Day has not occurred as of the eighth Trading Day for such Underlying Stock after the originally
scheduled Calculation Day, that eighth Trading Day shall be deemed to be the Calculation Day for such Underlying Stock. If a Calculation Day has 

  
 4 

 
been postponed eight Trading Days for an Underlying Stock after the originally scheduled Calculation Day and a Market Disruption Event occurs or is continuing with respect to such Underlying
Stock on such eighth Trading Day, the Calculation Agent will determine the Closing Price (as defined below) of such Underlying Stock on such eighth Trading Day by using its good faith estimate of the Closing Price that would have prevailed for such
Underlying Stock on such day. Notwithstanding the postponement of a Calculation Day for an Underlying Stock due to a Market Disruption Event with respect to such Underlying Stock on such Calculation Day, the originally scheduled Calculation Day will
remain the Calculation Day for the other Underlying Stock if such other Underlying Stock is not affected by a Market Disruption Event on such day. 

“Calculation Agent Agreement” shall mean the Calculation Agent Agreement dated as of March 18, 2015
between the Company and the Calculation Agent, as amended from time to time. 
 “Calculation Agent” shall
mean the Person that has entered into the Calculation Agent Agreement with the Company providing for, among other things, the determination of whether this Security will be automatically called prior to stated maturity and whether a Contingent
Coupon Payment will be made, the Call Price, if any, and the Redemption Amount, if any, which term shall, unless the context otherwise requires, include its successors under such Calculation Agent Agreement. The initial Calculation Agent shall be
Wells Fargo Securities, LLC. Pursuant to the Calculation Agent Agreement, the Company may appoint a different Calculation Agent from time to time after the initial issuance of this Security without the consent of the Holder of this Security and
without notifying the Holder of this Security. 
 Certain Definitions 

A “Trading Day” with respect to an Underlying Stock means a day, as determined by the Calculation Agent, on
which trading is generally conducted on the principal trading market for such Underlying Stock (as determined by the Calculation Agent, in its sole discretion), the Chicago Mercantile Exchange and the Chicago Board Options Exchange and in the over-the-counter market for equity securities in the United States. 

The “Closing Price” for one share of an Underlying Stock (or one unit of any other security for which a
Closing Price must be determined) on any Trading Day means: 
  

	 	•	 	 if such Underlying Stock (or any such other security) is listed or admitted to trading on a national
securities exchange, the official closing price on such day published by the principal United States securities exchange registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on which such Underlying
Stock (or any such other security) is listed or admitted to trading; or 

  

	 	•	 	 if such Underlying Stock (or any such other security) is not listed or admitted to trading on any national
securities exchange but is included in the OTC Bulletin Board Service (the “OTC Bulletin Board”) operated by the Financial Industry Regulatory Authority, Inc. (“FINRA”), the last reported sale price of the principal
trading session on the OTC Bulletin Board on such day. 

  
 5 

 If such Underlying Stock (or any such other security) is listed or admitted
to trading on any national securities exchange but the official closing price is not available pursuant to the preceding sentence, then the Closing Price for one share of such Underlying Stock (or one unit of any such other security) on any Trading
Day will mean the last reported sale price of the principal trading session on the over-the-counter market as reported on the OTC Bulletin Board on such day. 

If the official closing price or the last reported sale price, as applicable, for such Underlying Stock (or any such other
security) is not available pursuant to either of the two preceding sentences, then the Closing Price per share for any Trading Day will be the mean, as determined by the Calculation Agent, of the bid price for such Underlying Stock (or any such
other security) obtained from as many recognized dealers in such security, but not exceeding three, as will make such bid prices available to the Calculation Agent. Bids of Wells Fargo Securities, LLC or any of its affiliates may be included in the
calculation of such mean, but only to the extent that any such bid is the highest of the bids obtained. The term “OTC Bulletin Board Service” will include any successor service thereto or, if the OTC Bulletin Board Service is
discontinued and there is no successor service thereto, the OTC Reporting Facility operated by FINRA. 
 Market Disruption Events 

A “Market Disruption Event,” with respect to an Underlying Stock, means the occurrence or existence of any of
the following events: 
  

	 	•	 	 a suspension, absence or material limitation of trading in such Underlying Stock on its primary market for
more than two hours of trading or during the one-half hour before the close of trading in that market, as determined by the Calculation Agent in its sole discretion; 

 

	 	•	 	 a suspension, absence or material limitation of trading in option or futures contracts relating to such
Underlying Stock, if available, in the primary market for those contracts for more than two hours of trading or during the one-half hour before the close of trading in that market, as determined by the
Calculation Agent in its sole discretion; 

  

	 	•	 	 such Underlying Stock does not trade on the New York Stock Exchange, the NASDAQ Global Select Market, the
NASDAQ Global Market or what was the primary market for such Underlying Stock, as determined by the Calculation Agent in its sole discretion; or 

  

	 	•	 	 any other event, if the Calculation Agent determines in its sole discretion that the event materially
interferes with the Company’s ability or the ability of any of its affiliates to unwind all or a material portion of a hedge with respect to this Security that the Company or its affiliates have effected or may effect. 

  
 6 

 The following events will not be Market Disruption Events: 

 

	 	•	 	 a limitation on the hours or number of days of trading in such Underlying Stock in its primary market, but
only if the limitation results from an announced change in the regular business hours of the relevant market; and 

  

	 	•	 	 a decision to permanently discontinue trading in the option or futures contracts relating to such Underlying
Stock. 

 For this purpose, a “suspension, absence or material limitation of trading” in the
applicable market will not include any time when that market is itself closed for trading under ordinary circumstances. In contrast, a “suspension, absence or material limitation of trading” in the applicable market for such Underlying
Stock or option or futures contracts relating to such Underlying Stock, as applicable, by reason of any of: 
  

	 	•	 	 a price change exceeding limits set by that market; 

 

	 	•	 	 an imbalance of orders relating to such Underlying Stock or those contracts; or 

 

	 	•	 	 a disparity in bid and asked quotes relating to such Underlying Stock or those contracts

 will constitute a “suspension, absence or material limitation of trading” in such Underlying Stock or those
contracts, as the case may be, in the applicable market. 
 Adjustment Events 

The Adjustment Factor for each Underlying Stock is initially 1.0. However, the Adjustment Factor for each Underlying Stock is
subject to adjustment by the Calculation Agent as a result of the dilution and reorganization events described in this section. 
 How adjustments
will be made 
 If one of the events described below occurs with respect to an Underlying Stock and the Calculation
Agent determines that the event has a dilutive or concentrative effect on the market price of such Underlying Stock, the Calculation Agent will calculate a corresponding adjustment to the Adjustment Factor for such Underlying Stock as the
Calculation Agent deems appropriate to account for that dilutive or concentrative effect. For example, if an adjustment is required because of a two-for-one stock split,
then the Adjustment Factor for such Underlying Stock will be adjusted by the Calculation Agent by multiplying the existing Adjustment Factor by a fraction whose numerator is the number of shares of such Underlying Stock outstanding immediately after
the stock split and whose denominator is the number of shares of such Underlying Stock outstanding immediately prior to the stock split. Consequently, the Adjustment Factor for such Underlying Stock will be adjusted to double the prior Adjustment
Factor, due to the corresponding decrease in the market price of such Underlying Stock. Adjustments will be made for events with an effective date or Ex-Dividend Date (as defined below), as applicable, from
but 

  
 7 

 
excluding the Pricing Date to and including the applicable Calculation Day (the “Adjustment Period”). 

The Calculation Agent will also determine the effective date of that adjustment, and the replacement of an Underlying Stock,
if applicable, in the event of a consolidation or merger or certain other events in respect of the applicable Underlying Stock Issuer. Upon making any such adjustment, the Calculation Agent will give notice as soon as practicable to the Trustee and
the Paying Agent, stating the adjustment to the Adjustment Factor of such Underlying Stock. The Calculation Agent will not be required to make any adjustments to the Adjustment Factor for purposes of calculating the Stock Closing Price for a
Calculation Day after the close of business on the such Calculation Day; provided that any such adjustments to the Adjustment Factor will be taken into account for purposes of determining the Stock Closing Price for any subsequent Calculation
Day. In no event, however, will an antidilution adjustment to the Adjustment Factor of an Underlying Stock during the term of this Security be deemed to change the Face Amount of this Security. 

If more than one event requiring adjustment occurs with respect to an Underlying Stock, the Calculation Agent will make an
adjustment for each event in the order in which the events occur, and on a cumulative basis. Thus, having made an adjustment for the first event, the Calculation Agent will adjust the Adjustment Factor for such Underlying Stock for the second event,
applying the required adjustment to the Adjustment Factor for such Underlying Stock as already adjusted for the first event, and so on for any subsequent events. 

For any dilution event described below, other than a consolidation or merger, the Calculation Agent will not have to adjust
the Adjustment Factor for an Underlying Stock unless the adjustment would result in a change to the Adjustment Factor of such Underlying Stock then in effect of at least 0.10%. The Adjustment Factor of such Underlying Stock resulting from any
adjustment will be rounded up or down, as appropriate, to the nearest one-hundred thousandth. 

If an event requiring an antidilution adjustment occurs with respect to an Underlying Stock, the Calculation Agent will make
the adjustment with a view to offsetting, to the extent practical, any change in the economic position of the Holder of this Security relative to this Security that results solely from that event. The Calculation Agent may, in its sole discretion,
modify the antidilution adjustments as necessary to ensure an equitable result. 
 The Calculation Agent will make all
determinations with respect to antidilution adjustments, including any determination as to whether an event requiring adjustment has occurred with respect to an Underlying Stock, as to the nature of the adjustment required for such Underlying Stock
and how it will be made or as to the value of any property distributed in a Reorganization Event (as defined below), and will do so in its sole discretion. In the absence of manifest error, those determinations will be conclusive for all purposes
and will be binding on the Holder of this Security and the Company, without any liability on the part of the Calculation Agent. The Holder of this Security will not be entitled to any compensation from the Company for any loss suffered as a result
of any of these determinations by the Calculation Agent. The Calculation Agent will provide information about the adjustments that it makes upon the written request of the Holder of this Security. 

  
 8 

 If any of the adjustments specified below is required to be made with
respect to an amount or value of any cash or other property that is distributed by an Underlying Stock Issuer organized outside the United States, such amount or value will be converted to U.S. dollars, as applicable, and will be reduced by any
applicable foreign withholding taxes that would apply to such distribution if such distribution were paid to a U.S. person that is eligible for the benefits of an applicable income tax treaty, if any, between the United States and the jurisdiction
of organization of such Underlying Stock Issuer, as determined by the Calculation Agent, in its sole discretion. 
 No
adjustments will be made for certain other events, such as offerings of common stock by an Underlying Stock Issuer for cash or in connection with the occurrence of a partial tender or exchange offer for an Underlying Stock by the Underlying Stock
Issuer of such Underlying Stock or any other person. 
 Stock Splits and Reverse Stock Splits 

A stock split is an increase in the number of a corporation’s outstanding shares of stock without any change in its
stockholders’ equity. Each outstanding share will be worth less as a result of a stock split. 
 A reverse stock split
is a decrease in the number of a corporation’s outstanding shares of stock without any change in its stockholders’ equity. Each outstanding share will be worth more as a result of a reverse stock split. 

If an Underlying Stock is subject to a stock split or a reverse stock split, then once the split has become effective the
Calculation Agent will adjust the Adjustment Factor for such Underlying Stock to equal the product of the prior Adjustment Factor of such Underlying Stock and the number of shares issued in such stock split or reverse stock split with respect to one
share of such Underlying Stock. 
 Stock Dividends 

In a stock dividend, a corporation issues additional shares of its stock to all holders of its outstanding stock in proportion
to the shares they own. Each outstanding share will be worth less as a result of a stock dividend. 
 If an Underlying Stock
is subject to a stock dividend payable in shares of such Underlying Stock that is given ratably to all holders of shares of such Underlying Stock, then once the dividend has become effective the Calculation Agent will adjust the Adjustment Factor
for such Underlying Stock on the Ex-Dividend Date to equal the sum of the prior Adjustment Factor for such Underlying Stock and the product of: 

 

	 	•	 	 the number of shares issued with respect to one share of such Underlying Stock, and 

 

	 	•	 	 the prior Adjustment Factor for such Underlying Stock. 

  
 9 

 The “Ex-Dividend
Date” for any dividend or other distribution is the first day on and after which such Underlying Stock trades without the right to receive that dividend or distribution. 

No Adjustments for Other Dividends and Distributions 

The Adjustment Factor for an Underlying Stock will not be adjusted to reflect dividends, including cash dividends, or other
distributions paid with respect to such Underlying Stock, other than: 
  

	 	•	 	 stock dividends described above, 

 

	 	•	 	 issuances of transferable rights and warrants as described in “ —Transferable Rights and
Warrants” below, 

  

	 	•	 	 distributions that are spin-off events described in “
—Reorganization Events” below, and 

  

	 	•	 	 Extraordinary Dividends described below. 

An “Extraordinary Dividend” means each of (a) the full amount per share of an Underlying Stock of any
cash dividend or special dividend or distribution that is identified by the applicable Underlying Stock Issuer as an extraordinary or special dividend or distribution, (b) the excess of any cash dividend or other cash distribution (that is not
otherwise identified by the applicable Underlying Stock Issuer as an extraordinary or special dividend or distribution) distributed per share of such Underlying Stock over the immediately preceding cash dividend or other cash distribution, if any,
per share of such Underlying Stock that did not include an extraordinary or special dividend (as adjusted for any subsequent corporate event requiring an adjustment as described herein, such as a stock split or reverse stock split) if such excess
portion of the dividend or distribution is more than 5.00% of the Closing Price of such Underlying Stock on the Trading Day preceding the Ex-Dividend Date for the payment of such cash dividend or other cash
distribution (such Closing Price, the “Extraordinary Dividend Base Closing Price”) and (c) the full cash value of any non-cash dividend or distribution per share of such Underlying Stock
(excluding Marketable Securities, as defined below). 
 If an Underlying Stock is subject to an Extraordinary Dividend, then
once the Extraordinary Dividend has become effective the Calculation Agent will adjust the Adjustment Factor for such Underlying Stock on the Ex-Dividend Date to equal the product of: 

 

	 	•	 	 the prior Adjustment Factor for such Underlying Stock, and 

 

	 	•	 	 a fraction, the numerator of which is the Extraordinary Dividend Base Closing Price of such Underlying Stock
on the Trading Day preceding the Ex-Dividend Date and the denominator of which is the amount by which the Extraordinary Dividend Base Closing Price of such Underlying Stock on the Trading Day preceding the Ex-Dividend Date exceeds the Extraordinary Dividend. 

  
 10 

 Notwithstanding anything herein, the initiation by an Underlying Stock
Issuer of an ordinary dividend on such Underlying Stock or any announced increase in the ordinary dividend on such Underlying Stock will not constitute an Extraordinary Dividend requiring an adjustment. 

To the extent an Extraordinary Dividend is not paid in cash or is paid in a currency other than U.S. dollars, the value of the
non-cash component or non-U.S. currency will be determined by the Calculation Agent, in its sole discretion. A distribution on an Underlying Stock that is a dividend
payable in shares of such Underlying Stock, an issuance of rights or warrants or a spin-off event and also an Extraordinary Dividend will result in an adjustment to the number of shares of such Underlying
Stock only as described in “—Stock Dividends” above, “—Transferable Rights and Warrants” below or “—Reorganization Events” below, as the case may be, and not as described here. 

Transferable Rights and Warrants 

If an Underlying Stock Issuer issues transferable rights or warrants to all holders of such Underlying Stock to subscribe for
or purchase such Underlying Stock at an exercise price per share that is less than the Closing Price of such Underlying Stock on the Trading Day before the Ex-Dividend Date for the issuance, then the
Adjustment Factor for such Underlying Stock will be adjusted to equal the product of: 
  

	 	•	 	 the prior Adjustment Factor for such Underlying Stock, and 

 

	 	•	 	 a fraction, (1) the numerator of which will be the number of shares of such Underlying Stock outstanding
at the close of trading on the Trading Day before the Ex-Dividend Date (as adjusted for any subsequent event requiring an adjustment hereunder) plus the number of additional shares of such Underlying Stock
offered for subscription or purchase pursuant to the rights or warrants and (2) the denominator of which will be the number of shares of such Underlying Stock outstanding at the close of trading on the Trading Day before the Ex-Dividend Date (as adjusted for any subsequent event requiring an adjustment hereunder) plus the number of additional shares of such Underlying Stock (referred to herein as the “Additional
Shares”) that the aggregate offering price of the total number of shares of such Underlying Stock so offered for subscription or purchase pursuant to the rights or warrants would purchase at the Closing Price on the Trading Day before the Ex-Dividend Date for the issuance. 

 The number of Additional Shares
will be equal to: 
  

	 	•	 	 the product of (1) the total number of additional shares of such Underlying Stock offered for
subscription or purchase pursuant to the rights or warrants and (2) the exercise price of the rights or warrants, divided by 

  

	 	•	 	 the Closing Price of such Underlying Stock on the Trading Day before the
Ex-Dividend Date for the issuance. 

  
 11 

 If the number of shares of such Underlying Stock actually delivered in
respect of the rights or warrants differs from the number of shares of such Underlying Stock offered in respect of the rights or warrants, then the Adjustment Factor for such Underlying Stock will promptly be readjusted to the Adjustment Factor for
such Underlying Stock that would have been in effect had the adjustment been made on the basis of the number of shares of such Underlying Stock actually delivered in respect of the rights or warrants. 

Reorganization Events 

Each of the following is a “Reorganization Event” with respect to an Underlying Stock: 

 

	 	•	 	 such Underlying Stock is reclassified or changed (other than in a stock split or reverse stock split),

  

	 	•	 	 the applicable Underlying Stock Issuer has been subject to a merger, consolidation or other combination and
either is not the surviving entity or is the surviving entity but all outstanding shares of such Underlying Stock are exchanged for or converted into other property, 

 

	 	•	 	 a statutory share exchange involving outstanding shares of such Underlying Stock and the securities of another
entity occurs, other than as part of an event described above, 

  

	 	•	 	 the applicable Underlying Stock Issuer sells or otherwise transfers its property and assets as an entirety or
substantially as an entirety to another entity, 

  

	 	•	 	 the applicable Underlying Stock Issuer effects a spin-off, other than
as part of an event described above (in a spin-off, a corporation issues to all holders of its common stock equity securities of another issuer), or 

 

	 	•	 	 the applicable Underlying Stock Issuer is liquidated, dissolved or wound up or is subject to a proceeding
under any applicable bankruptcy, insolvency or other similar law, or another entity completes a tender or exchange offer for all the outstanding shares of such Underlying Stock. 

Adjustments for Reorganization Events 

If a Reorganization Event occurs with respect to an Underlying Stock, then the Calculation Agent will adjust the Adjustment
Factor for such Underlying Stock to reflect the amount and type of property or properties—whether cash, securities, other property or a combination thereof—that a holder of one share of such Underlying Stock would have been entitled to
receive in relation to the Reorganization Event. This new property is referred to as the “Reorganization Property.” 

  
 12 

 Reorganization Property can be classified into two categories: 

 

	 	•	 	 an equity security listed on a national securities exchange, which is referred to generally as a
“Marketable Security” and, in connection with a particular Reorganization Event, “New Stock,” which may include any tracking stock, any stock received in a spin-off (“Spin-Off Stock”) or any Marketable Security received in exchange for the applicable Underlying Stock; and 

  

	 	•	 	 cash and any other property, assets or securities other than Marketable Securities (including equity
securities that are not listed, that are traded over the counter or that are listed on a non-U.S. securities exchange), which is referred to as “Non-Stock
Reorganization Property.” 

 For the purpose of making an adjustment required by a Reorganization
Event, the Calculation Agent, in its sole discretion, will determine the value of each type of the Reorganization Property. For purposes of valuing any New Stock, the Calculation Agent will use the Closing Price of the security on the relevant
Trading Day. The Calculation Agent will value Non-Stock Reorganization Property in any manner it determines, in its sole discretion, to be appropriate. In connection with a Reorganization Event in which
Reorganization Property includes New Stock, for the purpose of determining the Adjustment Factor for any New Stock as described below, the term “New Stock Reorganization Ratio” means the product of (i) the number of shares of
the New Stock received with respect to one share of such Underlying Stock and (ii) the Adjustment Factor for the applicable Underlying Stock on the Trading Day immediately prior to the effective date of the Reorganization Event. 

If a holder of shares of the applicable Underlying Stock may elect to receive different types or combinations of types of
Reorganization Property in the Reorganization Event, the Reorganization Property will consist of the types and amounts of each type distributed to a holder of shares of such Underlying Stock that makes no election, as determined by the Calculation
Agent in its sole discretion. 
 If any Reorganization Event occurs with respect to an Underlying Stock, then on and after
the effective date for such Reorganization Event (or, if applicable, in the case of Spin-Off Stock, the Ex-Dividend Date for the distribution of such Spin-Off Stock) the term “Underlying Stock” herein will be deemed to mean the following with respect to such Underlying Stock, and for each share of such Underlying Stock, New Stock and/or
Replacement Stock so deemed to constitute such Underlying Stock, the Adjustment Factor for such Underlying Stock will be equal to the applicable number indicated: 
  

	 	(a)	 if such Underlying Stock continues to be outstanding: 

 

	 	(1)	 that Underlying Stock (if applicable, as reclassified upon the issuance of any tracking stock) at the
Adjustment Factor for such Underlying Stock in effect on the Trading Day immediately prior to the effective date of the Reorganization Event; and 

  
 13 

	 	(2)	 if the Reorganization Property includes New Stock, a number of shares of New Stock equal to the New Stock
Reorganization Ratio; 

 provided that, if any Non-Stock
Reorganization Property is received in the Reorganization Event, the results of (a)(1) and (a)(2) above will each be multiplied by the “Gross-Up Multiplier,” which will be equal to a fraction,
the numerator of which is the Closing Price of the original Underlying Stock on the Trading Day immediately prior to the effective date of the Reorganization Event and the denominator of which is the amount by which such Closing Price of the
original Underlying Stock exceeds the value of the Non-Stock Reorganization Property received per share of such Underlying Stock as determined by the Calculation Agent as of the close of trading on such
Trading Day; or 
  

	 	(b)	 if such Underlying Stock is surrendered for Reorganization Property: 

 

	 	(1)	 that includes New Stock, a number of shares of New Stock equal to the New Stock Reorganization Ratio; provided
that, if any Non-Stock Reorganization Property is received in the Reorganization Event, such number will be multiplied by the Gross-Up Multiplier; or

  

	 	(2)	 that consists exclusively of Non-Stock Reorganization Property:

  

	 	(i)	 if the surviving entity has Marketable Securities outstanding following the Reorganization Event and either
(A) such Marketable Securities were in existence prior to such Reorganization Event or (B) such Marketable Securities were exchanged for previously outstanding Marketable Securities of the surviving entity or its predecessor
(“Predecessor Stock”) in connection with such Reorganization Event (in either case of (A) or (B), the “Successor Stock”), a number of shares of the Successor Stock determined by the Calculation Agent on the
Trading Day immediately prior to the effective date of such Reorganization Event equal to the Adjustment Factor for such Underlying Stock in effect on the Trading Day immediately prior to the effective date of such Reorganization Event multiplied by
a fraction, the numerator of which is the value of the Non-Stock Reorganization Property per share of such Underlying Stock on such Trading Day and the denominator of which is the Closing Price of the
Successor Stock on such Trading Day (or, in the case of Predecessor Stock, the Closing Price of the Predecessor Stock multiplied by the number of shares of the Successor Stock received with respect to one share of the Predecessor Stock); or

  

	 	(ii)	 if the surviving entity does not have Marketable Securities outstanding, or if there is no surviving entity
(in each case, a “Replacement Stock Event”), a number of shares of Replacement Stock (selected as defined below) with an aggregate value on the effective date of such Reorganization Event equal to the value of the Non-Stock Reorganization Property multiplied by 

  
 14 

	 	 
the Adjustment Factor for such Underlying Stock in effect on the Trading Day immediately prior to the effective date of such Reorganization Event. 

If a Reorganization Event occurs with respect to the shares of an Underlying Stock and the Calculation Agent adjusts the
Adjustment Factor of such Underlying Stock to reflect the Reorganization Property in the event as described above, the Calculation Agent will make further antidilution adjustments for any later events that affect the Reorganization Property, or any
component of the Reorganization Property, comprising the new Adjustment Factor of such Underlying Stock. The Calculation Agent will do so to the same extent that it would make adjustments if the shares of such Underlying Stock were outstanding and
were affected by the same kinds of events. If a subsequent Reorganization Event affects only a particular component of the number of shares of such Underlying Stock, the required adjustment will be made with respect to that component as if it alone
were the number of shares of such Underlying Stock. 
 For purposes of adjustments for Reorganization Events, in the case of
a consummated tender or exchange offer or going-private transaction involving Reorganization Property of a particular type, Reorganization Property will be deemed to include the amount of cash or other property paid by the offeror in the tender or
exchange offer with respect to such Reorganization Property (in an amount determined on the basis of the rate of exchange in such tender or exchange offer or going-private transaction). In the event of a tender or exchange offer or a going-private
transaction with respect to Reorganization Property in which an offeree may elect to receive cash or other property, Reorganization Property will be deemed to include the kind and amount of cash and other property received by offerees who elect to
receive cash. 
 Replacement Stock Events 

Following the occurrence of a Replacement Stock Event described in paragraph (b)(2)(ii) above or in “—Delisting of
American Depositary Shares or Termination of American Depositary Receipt Facility” below with respect to an Underlying Stock, the Stock Closing Price of the applicable Underlying Stock on any Calculation Day on or after the effective
date of the Replacement Stock Event will be determined by reference to a Replacement Stock and an Adjustment Factor (subject to any further antidilution adjustments) for such Replacement Stock as determined in accordance with the following
paragraphs. 
 The “Replacement Stock” will be the stock having the closest “Option Period
Volatility” to the applicable original Underlying Stock among the stocks that then comprise the Replacement Stock Selection Index (or, if publication of such index is discontinued, any successor or substitute index selected by the
Calculation Agent in its sole discretion) with the same GICS Code (as defined below) as the applicable original Underlying Stock Issuer; provided, however, that a Replacement Stock will not include (i) any stock that is subject to a trading
restriction under the trading restriction policies of the Company, the hedging counterparties of the Company or any of their affiliates that would materially limit the ability of the Company, the hedging counterparties of the Company or any of their
affiliates to hedge this Security with respect to such stock or (ii) any stock for which the aggregate number of shares to be referenced by this Security (equal to the product of (a) (i) $100 divided by (ii) the Starting Price of
the applicable Underlying Stock, (b) the Adjustment Factor that would be in effect 

  
 15 

 
immediately after selection of such stock as the Replacement Stock and (c) (i) the aggregate face amount outstanding divided by (ii) $1,000) exceeds 25% of the ADTV (as defined in
Rule 100(b) of Regulation M under the Exchange Act) for such stock as of the effective date of the Replacement Stock Event (an “Excess ADTV Stock”). 

If a Replacement Stock is selected in connection with a Reorganization Event for an original Underlying Stock, the Adjustment
Factor with respect to such Replacement Stock will be equal to the number of shares of such Replacement Stock with an aggregate value, based on the Closing Price on the effective date of such Reorganization Event, equal to the product of
(a) the value of the Non-Stock Reorganization Property received per share of such original Underlying Stock and (b) the Adjustment Factor of such Underlying Stock in effect on the Trading Day
immediately prior to the effective date of such Reorganization Event. If a Replacement Stock is selected in connection with an ADS Termination Event (as defined below), the Adjustment Factor with respect to such Replacement Stock will be equal to
the number of shares of such Replacement Stock with an aggregate value, based on the Closing Price on the Change Date (as defined below), equal to the product of (x) the Closing Price of the original Underlying Stock on the Change Date and
(y) the Adjustment Factor in effect on the Trading Day immediately prior to the Change Date. 
 The “Option
Period Volatility” means, in respect of any Trading Day, the volatility (calculated by referring to the Closing Price of the applicable Underlying Stock on its primary exchange) for a period equal to the 125 Trading Days immediately
preceding the announcement date of the Reorganization Event, as determined by the Calculation Agent. 
 “GICS
Code” means the Global Industry Classification Standard (“GICS”) sub-industry code assigned to the applicable Underlying Stock Issuer; provided, however, if (i) there is no other
stock in the Replacement Stock Selection Index in the same GICS sub-industry or (ii) a Replacement Stock (a) for which there is no trading restriction and (b) that is not an Excess ADTV Stock
cannot be identified from the Replacement Stock Selection Index in the same GICS sub-industry, the GICS Code will mean the GICS industry code assigned to such original Underlying Stock Issuer. If no GICS Code
has been assigned to such original Underlying Stock Issuer, the applicable GICS Code will be determined by the Calculation Agent to be the GICS sub-industry code assigned to companies in the same sub-industry (or, subject to the proviso in the preceding sentence, industry, as applicable) as such original Underlying Stock Issuer at the time of the relevant Replacement Stock Event. 

The “Replacement Stock Selection Index” means the S&P
500® Index. 
 Delisting of American Depositary Shares or Termination of American
Depositary Receipt Facility. 
 If an Underlying Stock is an American Depositary Share and such Underlying
Stock is no longer listed or admitted to trading on a U.S. securities exchange registered under the Exchange Act or included in the OTC Bulletin Board Service operated by FINRA, or if the American depositary receipt facility between the applicable
Underlying Stock Issuer and the depositary is terminated for any reason (each, an “ADS Termination Event”), then, on the last 

  
 16 

 
Trading Day on which the applicable Underlying Stock is listed or admitted to trading or the last Trading Day immediately prior to the date of such termination, as applicable (the “Change
Date”), a Replacement Stock Event shall be deemed to occur. 
 Calculation Agent 

The Calculation Agent will determine whether this Security will be automatically called prior to stated maturity and whether a
Contingent Coupon Payment will be made, the Call Price, if any, and the Redemption Amount, if any. In addition, the Calculation Agent will (i) determine the Closing Prices of the Underlying Stocks under the circumstances described in this
Security, (ii) determine if adjustments are required to the Closing Price or Adjustment Factor of an Underlying Stock under the circumstances described in this Security, (iii) select a Replacement Stock under the circumstances described in
this Security and (iv) determine whether a Market Disruption Event has occurred. 
 The Company covenants that, so long
as this Security is Outstanding, there shall at all times be a Calculation Agent (which shall be a broker-dealer, bank or other financial institution) with respect to this Security. 

All determinations made by the Calculation Agent with respect to this Security will be at the sole discretion of the
Calculation Agent and, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and the Holder of this Security. 

Redemption and Repayment 

This Security is not subject to repayment at the option of the Holder hereof prior to December 16, 2024. Except as set
forth above under “Automatic Call,” this Security is not subject to redemption prior to December 16, 2024. This Security is not entitled to any sinking fund. 

Acceleration 
 If
an Event of Default, as defined in the Indenture, with respect to this Security shall occur and be continuing, the Redemption Amount (calculated as set forth in the next two sentences) of this Security may be declared due and payable in the manner
and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted under the Indenture will be equal to the Redemption Amount hereof calculated as provided herein, plus a portion of a final
Contingent Coupon Payment, if any. The Redemption Amount and any final Contingent Coupon Payment will be calculated as though the date of acceleration were the Final Calculation Day. The final Contingent Coupon Payment, if any, will be prorated from
and including the immediately preceding Contingent Coupon Payment Date to but excluding the date of acceleration. 
  

 

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions
shall for all purposes have the same effect as if set forth at this place. 

  
 17 

 Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature or its duly authorized agent under the Indenture referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid
or obligatory for any purpose.

MEDIUM-TERM NOTE, SERIES K 

Due Nine Months or More From Date of Issue 

Principal at Risk Securities Linked to the Lowest Performing of the 

Common Stock of Celgene Corporation and the Common Stock of 

Gilead Sciences, Inc. due December 16, 2024 

This Security is one of a duly authorized issue of securities of the Company (herein called the
“Securities”), issued and to be issued in one or more series under an indenture dated as of July 21, 1999, as amended or supplemented from time to time (herein called the “Indenture”), between the Company and
Citibank, N.A., as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is
one of the series of the Securities designated as Medium-Term Notes, Series K, of the Company, which series is limited to an aggregate principal amount or face amount, as applicable, of $25,000,000,000 or the equivalent thereof in one or more
foreign or composite currencies. The amount payable on the Securities of this series may be determined by reference to the performance of one or more equity-, commodity- or currency-based indices, exchange traded funds, securities, commodities,
currencies, statistical measures of economic or financial performance, or a basket comprised of two or more of the foregoing, or any other market measure or may bear interest at a fixed rate or a floating rate. The Securities of this series may
mature at different times, be redeemable at different times or not at all, be repayable at the option of the Holder at different times or not at all and be denominated in different currencies. 

Article Sixteen of the Indenture shall not apply to this Security. 

The Securities are issuable only in registered form without coupons and will be either
(a) book-entry securities represented by one or more Global Securities recorded in the book-entry system maintained by the Depositary or (b) certificated
securities issued to and registered in the names of, the beneficial owners or their nominees. 
 The Company agrees, to the
extent permitted by law, not to voluntarily claim the benefits of any laws concerning usurious rates of interest against a Holder of this Security. 

Modification and Waivers 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights
and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the 

  
 20 

 
Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected, acting together as a class. The Indenture also
contains provisions permitting the Holders of a majority in principal amount of the Securities of all series at the time Outstanding affected by certain provisions of the Indenture, acting together as a class, on behalf of the Holders of all
Securities of such series, to waive compliance by the Company with those provisions of the Indenture. Certain past defaults under the Indenture and their consequences may be waived under the Indenture by the Holders of a majority in principal amount
of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series. Solely for the purpose of determining whether any consent, waiver, notice or other action or Act to be taken or given by the Holders
of Securities pursuant to the Indenture has been given or taken by the Holders of Outstanding Securities in the requisite aggregate principal amount, the principal amount of this Security will be deemed to be equal to the amount set forth on the
face hereof as the “Face Amount” hereof. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

Defeasance 

Section 403 and Article Fifteen of the Indenture and the provisions of clause (ii) of Section 401(1)(B) of the
Indenture, relating to defeasance at any time of (a) the entire indebtedness on this Security and (b) certain restrictive covenants and certain Events of Default, upon compliance by the Company with certain conditions set forth therein,
shall not apply to this Security. The remaining provisions of Section 401 of the Indenture shall apply to this Security. 
 Authorized
Denominations 
 This Security is issuable only in registered form without coupons in denominations of $1,000 or any
amount in excess thereof which is an integral multiple of $1,000. 
 Registration of Transfer 

Upon due presentment for registration of transfer of this Security at the office or agency of the Company in the City of
Minneapolis, Minnesota, a new Security or Securities of this series, with the same terms as this Security, in authorized denominations for an equal aggregate Face Amount will be issued to the transferee in exchange herefor, as provided in the
Indenture and subject to the limitations provided therein and to the limitations described below, without charge except for any tax or other governmental charge imposed in connection therewith. 

This Security is exchangeable for definitive Securities in registered form only if (x) the Depositary notifies the
Company that it is unwilling or unable to continue as Depositary for this Security or if at any time the Depositary ceases to be a clearing agency registered under the Exchange Act and a successor depositary is not appointed within 90 days
after the Company receives such notice or becomes aware of such ineligibility, (y) the Company in its sole discretion determines that this Security shall be exchangeable for definitive Securities in registered form and notifies the Trustee
thereof or (z) an Event of Default with respect to the Securities represented hereby has occurred and is continuing. If this Security is exchangeable pursuant to the preceding 

  
 21 

 
sentence, it shall be exchangeable for definitive Securities in registered form, bearing interest at the same rate, having the same date of issuance, Stated Maturity Date and other terms and of
authorized denominations aggregating a like amount. 
 This Security may not be transferred except as a whole by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor of the Depositary or a nominee of such successor. Except as
provided above, owners of beneficial interests in this Global Security will not be entitled to receive physical delivery of Securities in definitive form and will not be considered the Holders hereof for any purpose under the Indenture. 

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

No reference herein to the Indenture and no provision of this Security or the Indenture shall alter or impair the obligation
of the Company, which is absolute and unconditional, to pay the Contingent Coupon Payments, if any, and the Redemption Amount or the Call Price, as applicable, on this Security at the times, place and rate, and in the coin or currency, herein
prescribed, except as otherwise provided in this Security. 
 No Personal Recourse 

No recourse shall be had for the payment of any Contingent Coupon Payments or the Redemption Amount or the Call Price, as
applicable, on this Security or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer or director, as such, past,
present or future, of the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as
part of the consideration for the issuance hereof, expressly waived and released. 
 Defined Terms 

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture
unless otherwise defined in this Security.

 24SETTLEMENT
AGREEMENT

 

This
Settlement Agreement (this “Agreement”) is entered into as of December 8, 2017 (the “Effective
Date”) by and among Iliad Research and Trading, L.P., a Utah limited partnership (“Lender”),
MGT Capital Investments, Inc., a Delaware corporation (“Company”), and MGT Mining One, Inc., a Delaware
corporation (“Mining Sub”, and together with Company, “Borrower”). Capitalized
terms used in this Agreement without definition shall have the meanings given to them in the Note (defined below). Each of Borrower
and Lender is sometimes referred to herein individually as a “Party” and collectively as the “Parties.”

 

A.
Borrower previously sold and issued to Lender that certain Secured Convertible Promissory Note dated May 18, 2017 in the original
principal amount of $1,355,000.00 (the “Note”) and that certain Warrant to Purchase Shares of Common
Stock (the “Warrant”) pursuant to that certain Securities Purchase Agreement dated May 18, 2017 by and
between Lender and Borrower (the “Purchase Agreement,” and together with the Note, the Warrant, and
all other documents entered into in conjunction therewith, the “Transaction Documents”).

 

B.
Certain disputes have arisen between the Parties regarding the Lender Conversion Price applicable to Lender Conversions under
the Note and the Exercise Price (as defined in the Warrant) to be used for exercises of the Warrant (the “Disputes”).

 

C.
Lender and Borrower have agreed, subject to the terms, amendments, conditions and understandings expressed in this Agreement,
to settle the Disputes as set forth herein.

 

NOW
THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree
as follows:

 

1.
Recitals. Each of the Parties hereto acknowledges and agrees that the recitals set forth above in this Agreement are true
and accurate, are contractual in nature, and are hereby incorporated into and made a part of this Agreement.

 

2.
Lender Conversion Price; Exercise Price. Borrower and Lender agree that, notwithstanding the terms of the Note and the
Warrant, the Lender Conversion Price and the Exercise Price shall each be equal to $0.75 per share of Common Stock as of the Effective
Date.

 

3.
Delivery of Conversion Shares. By its execution below, Company acknowledges its receipt of the Conversion Notice attached
hereto as Exhibit A, pursuant to which Company agrees to deliver to Lender 1,909,863 Conversion Shares (the “Conversion
Shares”), notwithstanding any contrary terms in the Note. Company agrees to deliver the Conversion Shares to Lender
in the manner prescribed in the Note for delivery of Conversion Shares, but in any event within five (5) Trading Days of the date
hereof. Upon Lender’s receipt of all of the Conversion Shares, Borrower shall be deemed to have paid the entire Outstanding
Balance of the Note in full.

 

4.
Warrant Shares; Cap. Borrower and Lender agree that, notwithstanding the terms of the Warrant, the number of Exercise Shares
(as defined in the Warrant) exercisable under the Warrant is hereby increased to 1,724,547. Moreover, Borrower and Lender further
agree that the number of Delivery Shares (as defined in the Warrant) deliverable under the Warrant shall not exceed 5,173,640.

 

    	 

     

    

 

5.
Ownership Limitations. Notwithstanding Company’s obligation to deliver the Conversion Shares to Lender pursuant to
Section 3 above or its obligations to deliver Delivery Shares to Lender pursuant to the terms of the Warrant (such Conversion
Shares and Delivery Shares, together, the “Shares”), each of Company and Lender acknowledge and agree
that such deliveries are subject to the ownership limitation provisions set forth in Section 12 of the Note and Section 2.2 of
the Warrant, respectively, and in the event the number of Shares Company is required to deliver to Lender exceeds the applicable
Maximum Percentage, Company agrees to reserve the Ownership Limitations Shares for the exclusive benefit of Lender and deliver
such Ownership Limitation Shares to Lender in accordance with the terms of Section 12 of the Note and Section 2.2 of the Warrant,
as applicable. In furtherance thereof, Company agrees to cause its transfer agent to establish a separate reserve of shares of
Common Stock equal to the number of Ownership Limitation Shares Company is required to reserve pursuant to Section 12 of the Note
and Section 2.2 of the Warrant, respectively, upon Lender’s delivery of written request to Company and its transfer agent.
Company agrees that it may not deny any exercise of the Warrant or Conversion of the Note on the grounds that such exercise would
cause the number of shares of Common Stock owned by Lender to exceed the Maximum Percentage; rather, in such event Company shall
comply with the terms of Section 12 of the Note and Section 2.2 of the Warrant, as applicable, and continue delivering Shares
to Lender pursuant to such provisions.

 

6.
Restrictions on Sales of Shares.

 

(a)
Volume Limitation. Lender agrees that, with respect to the sale of any Shares by it and UAHC Ventures, LLC, a Nevada limited
liability company and affiliate of Lender (“UAHC Ventures,” and together with Lender, “Investor”),
Investor’s Net Sales (as defined below) of such Shares shall not exceed (i) twelve percent (12%) of Company’s daily
dollar trading volume on any given Trading Day (which, for purposes hereof, means the number of shares traded during such Trading
Day multiplied by the volume weighted average price per share for such Trading Day), and (ii) ten percent (10%) of Company’s
weekly dollar trading volume in any given week (which, for purposes hereof, means the number of shares traded during such calendar
week multiplied by the volume weighted average price per share for such week) (the “Volume Limitation”).
For the avoidance of doubt, the Volume Limitation shall apply to Lender and UAHC Ventures in the aggregate, as determined by Lender
and UAHC Ventures, and there shall be no separate cap or limitation applicable to either Lender or UAHC Ventures. For purposes
of this Agreement, the term “Net Sales” means the gross proceeds from sales of the Shares sold in a calendar
week minus any trading commissions or costs associated with clearing and selling such Shares minus the purchase price paid for
any shares of Common Stock purchased on the open market during such week. For the avoidance of doubt, any amounts received by
Investor in connection with previous sales of shares either entity acquired in any way shall not be deemed to be Net Sales.

 

(b)
Breach of Volume Limitation. Borrower and Lender agree that in the event Investor breaches the Volume Limitation where
its Net Sales of Shares during any given period exceed the dollar volume it is permitted to sell during such period pursuant to
the Volume Limitation (such excess, the “Excess Sales”), then in such event, as Borrower’s sole and exclusive
remedy for such breach (and which breach may not be used as a defense to Borrower’s performance of its obligations hereunder),
Investor shall be obligated to pay to Borrower in cash a fee in the amount of 25% of the Excess Sales (the “Excess Sales
Fee”) upon Borrower’s delivery to Investor of a written notice setting for its basis for charging such Excess
Sales Fee. For illustration purposes only, if Company’s weekly dollar trading volume was $400,000.00 for a calendar week,
Investor would be entitled to Net Sales of up to $40,000.00 during that week. If Investor’s Net Sales for such week were
equal to $50,000.00, and Investor had sold the maximum number of Shares it could within the Volume Limitation during each prior
week, then in such event Investor would be obligatd to pay to Borrower an Excess Sales Fee in the amount of $2,500.00 (($50,000.00
- $40,000.00) x 25%). For the avoidance of doubt, in such event Investor shall be entitled to retain the Excess Sales and shall
have no obligation to return the Excess Sales to Borrower.

7.
Failure to Comply. Borrower understands that the amendments to the Transaction Documents set forth herein, Lender’s
agreement to settle the Note for the Conversion Shares, and all other obligations, restrictions, and limitations of or on Lender
hereunder shall terminate immediately upon the occurrence of any breach of this Agreement (including, without limitation, Borrower’s
failure to deliver Conversion Shares as and when required hereunder). In any such case, Lender may seek all recourse available
to it under the terms of the Transaction Documents, this Agreement, or applicable law following any breach.

 

8.
Representations, Warranties and Agreements. In order to induce Lender to enter into this Agreement, Borrower, for itself,
and for its affiliates, successors and assigns, hereby acknowledges, represents, warrants and agrees as follows:

 

(a)
Borrower has full power and authority to enter into this Agreement and to incur and perform all obligations and covenants contained
herein, all of which have been duly authorized by all proper and necessary action. No consent or approval of Borrower, and no
consent, approval, filing or registration with or notice to any governmental authority is required as a condition to the validity

(b)
All understandings, representations, warranties and recitals contained or expressed in this Agreement are true, accurate, complete,
and correct in all respects; and no such understanding, representation, warranty, or recital fails or omits to state or otherwise
disclose any material fact or information necessary to prevent such understanding, representation, warranty, or recital from being
misleading. Borrower acknowledges and agrees that Lender has been induced in part to enter into this Agreement based upon Lender’s
justifiable reliance on the truth, accuracy, and completeness of all understandings, representations, warranties, and recitals
contained in this Agreement. There is no fact known to Borrower or which should be known to Borrower which Borrower has not disclosed
to Lender on or prior to the date hereof which would or could materially and adversely affect the understandings of Lender expressed
in this Agreement or any representation, warranty, or recital contained in this Agreement.

 

(c)
Except as expressly set forth in this Agreement, Borrower acknowledges and agrees that neither the execution and delivery of this
Agreement nor any of the terms, provisions, covenants, or agreements contained in this Agreement shall in any manner release,
impair, lessen, modify, waive, or otherwise affect the liability and obligations of Borrower under the terms of the Judgment or
applicable law related thereto.

(d)
Borrower has no defenses, affirmative or otherwise, rights of setoff, rights of recoupment, claims, counterclaims, actions or
causes of action of any kind or nature whatsoever against Lender, directly or indirectly, arising out of, based upon, or in any
manner connected with, the transactions contemplated hereby, whether known or unknown, which occurred, existed, was taken, permitted,
or begun prior to the execution of this Agreement. To the extent any such defenses, affirmative or otherwise, rights of setoff,
rights of recoupment, claims, counterclaims, actions or causes of action exist or existed, such defenses, rights, claims, counterclaims,
actions and causes of action are hereby waived, discharged and released. Borrower hereby acknowledges and agrees that the execution
of this Agreement by Lender shall not constitute an acknowledgment of or admission by Lender of the existence of any claims or
of liability for any matter or precedent upon which any claim or liability may be asserted.

 

(e)
Borrower hereby acknowledges that it has freely and voluntarily entered into this Agreement after an adequate opportunity and
sufficient period of time to review, analyze, and discuss (i) all terms and conditions of this Agreement, (ii) any and all other
documents executed and delivered in connection with the transactions contemplated by this Agreement, and (iii) all factual and
legal matters relevant to this Agreement and/or any and all such other documents, with counsel freely and independently selected
by Borrower (or had the opportunity to be represented by counsel). Borrower further acknowledges and agrees that it has actively
and with full understanding participated in the negotiation of this Agreement and all other documents executed and delivered in
connection with this Agreement after consultation and review with its counsel (or had the opportunity to be represented by counsel),

Agreement have been negotiated at arm’s-length, and that this Agreement and all such other documents have been negotiated,
prepared, and executed without fraud, duress, undue influence, or coercion of any kind or nature whatsoever having been exerted
by or imposed upon any Party by any other Party. No provision of this Agreement or such other documents shall be construed against
or interpreted to the disadvantage of any Party by any court or other governmental or judicial authority by reason of such Party
having or being deemed to have structured, dictated, or drafted such provision.

 

(f)
Borrower is solvent as of the date of this Agreement, and none of the terms or provisions of this Agreement shall have the effect

in connection herewith are being given for full and fair consideration and exchange of value.

(h)

compliance or observance of any of the terms and conditions of this Agreement and/or any of the other documents executed and delivered
in connection with this Agreement.

(i)

10.
Arbitration. By its execution of this Agreement, each Party agrees to be bound by the Arbitration Provisions (as defined
in the Purchase Agreement) set forth as an exhibit to the Purchase Agreement and the Parties agree to submit all Claims (as defined
in the Arbitration Provisions) arising under this Agreement or any Transaction Document or other agreement between the Parties
and their affiliates to binding arbitration pursuant to the Arbitration Provisions.

 

11.
Governing Law; Venue. This Agreement shall be governed by and interpreted in accordance with the laws of the State of Utah
without regard to the principles of conflict of laws. Each Party consents to and expressly agrees that the exclusive venue for
arbitration of any dispute arising out of or relating to this Agreement or any Transaction Document or the relationship of the
Parties or their affiliates shall be in Salt Lake County, Utah. Without modifying the Parties obligations to resolve disputes
hereunder or under any Transaction Document pursuant to the Arbitration Provisions, each Party hereto submits to the exclusive
jurisdiction of any state or federal court sitting in Salt Lake County, Utah in any proceeding arising out of or relating to this
Agreement and agrees that all Claims in respect of the proceeding may only be heard and determined in any such court and hereby
expressly submits to the exclusive personal jurisdiction and venue of such court for the purposes hereof and expressly waives
any claim of improper venue and any claim that such courts are an inconvenient forum. Each Party hereto hereby irrevocably consents
to the service of process of any of the aforementioned courts in any such proceeding by the mailing of copies thereof by registered
or certified mail, postage prepaid, to its address as set forth in the Purchase Agreement, such service to become effective ten
(10) days after such mailing. BORROWER HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY
TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION
CONTEMPLATED HEREBY.

 

12.
Counterparts. This Agreement may be executed in any number of counterparts with the same effect as if all signing parties
had signed the same document. All counterparts shall be construed together and constitute the same instrument. The exchange of
copies of this Agreement and of signature pages by facsimile transmission or other electronic transmission (including email) shall
constitute effective execution and delivery of this Agreement as to the Parties and may be used in lieu of the original Agreement
for all purposes. Signatures of the Parties transmitted by facsimile transmission or other electronic transmission (including
email) shall be deemed to be their original signatures for all purposes.

 

13.
Attorneys’ Fees. In the event of any arbitration or action at law or in equity to enforce or interpret the terms
of this Agreement, the Parties agree that the Party who is awarded the most money shall be deemed the prevailing Party for all
purposes and shall therefore be entitled to an additional award of the full amount of the attorneys’ fees and expenses paid
by such prevailing Party in connection with the arbitration, litigation and/or dispute without reduction or apportionment based
upon the individual claims or defenses giving rise to the fees and expenses. Nothing herein shall restrict or impair an arbitrator’s
or a court’s power to award fees and expenses for frivolous or bad faith pleading.

14.
No Reliance. Borrower acknowledges and agrees that neither Lender nor any of its officers, directors, members, managers,
equity holders, representatives or agents has made any representations or warranties to Borrower or any of its agents, representatives,
officers, directors, or employees except as expressly set forth in this Agreement and, in making its decision to enter into the
transactions contemplated by this Agreement, Borrower is not relying on any representation, warranty, covenant or promise of Lender
or its officers, directors, members, managers, equity holders, agents or representatives other than as set forth in this Agreement.

 

15.
Severability. If any part of this Agreement is construed to be in violation of any law, such part shall be modified to
achieve the objective of the Parties to the fullest extent permitted and the balance of this Agreement shall remain in full force
and effect.

 

16.
Entire Agreement. This Agreement and all other documents referred to herein, supersede all other prior oral or written
agreements between Borrower, Lender, its affiliates and persons acting on its behalf with respect to the matters discussed herein,
and this Agreement and the instruments referenced herein contain the entire understanding of the Parties with respect to the matters
covered herein and therein and, except as specifically set forth herein or therein, neither Lender nor Borrower makes any representation,
warranty, covenant or undertaking with respect to such matters.

of this Agreement may be waived except in writing signed by the Party against whom such waiver is sought to be enforced.

 

18.
Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective
successors and assigns. This Agreement or any of the severable rights and obligations inuring to the benefit of or to be performed
by Lender hereunder may be assigned by Lender to a third party, including its affiliates, in whole or in part. Borrower may not
assign this Agreement or any of its obligations herein without the prior written consent of Lender.

 

19.
Time of Essence. Time is of the essence of this Agreement.

this Agreement to be given to Borrower or Lender shall be given at such address as has been previously provided to the other Party.
