 ARTICLE 1  

EXERCISE 

1.1 Conditions to Exercise. 

(a) This Warrant shall be exercisable for 98,958 shares of the Company’s Common Stock (subject to
adjustment as provided herein) in whole or in part at any time on or after February 1, 2019 until the Expiration Date. 

(b) The exercise price for each share of Common Stock receivable hereunder shall be the lower of (x)
$2.40 (as adjusted per Article 2) and (y) as determined on February 1, 2019 the lowest of the 5-day volume-weighted average closing prices of the Company’s common stock for the last 5 trading
days in the months of September 2018, October 2018, November 2018, December 2018 and January 2019. 
 (c) To
the extent that the Company has Paid in Full (as defined in the Credit Agreement) in cash all of the Obligations (as defined in the Credit Agreement) under the Credit Agreement on or prior to October 31, 2018, then Quantum shall have
the right to buy back all or any portion of the Warrant, for a price of $.001 per share multiplied by the Shares issuable under the portion of the Warrant being repurchased, and the Warrant would only be exercisable for such reduced amount as
of February 1, 2019 until the Expiration Date. In order to exercise such repurchase right (if applicable), the Company must have given notice to the Holder on or prior to December 31, 2018.

 1.2 Method of Exercise. Holder may exercise any portion of this
Warrant that is exercisable by delivering a duly completed and executed Notice of Exercise in substantially the form attached as Appendix I to the principal office of the Company. Unless Holder is exercising the cashless exercise right set forth in
Section 1.3, Holder shall also deliver to the Company a check, wire transfer (to an account designated in writing by the Company), or other form of payment acceptable to the Company for the aggregate Warrant Price for the Shares being
purchased. 
 1.3 Cashless Exercise Right. In lieu of exercising this Warrant as specified in Section 1.2, Holder
may from time to time, in its sole discretion, exercise this Warrant in whole or in part as to the portion of the Warrant that is exercisable and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise
for the aggregate Warrant Price pursuant to Section 1.2, elect instead to receive upon such exercise the “net number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”):

  

									
	     
	  	 X
	  	 =
	  	 Y (A – B)
	  	
	  	A	  	

 Where: 

 

							
		 	 X
	  	 =
	  	 The number of Shares to be issued to Holder

				
		 	 Y
	  	 =
	  	 The number of Shares being exercised under this Warrant or, if only a portion of the Warrant is being exercised, the
portion of the Warrant being canceled (at the date of such calculation)

				
		 	 A
	  	 =
	  	 The fair market value of one Share (at the date of such calculation)

				
		 	 B
	  	 =
	  	 The Warrant Price per share (as adjusted to the date of such calculation)

 1.4 Calculation of FMV. For purposes of the calculation above, the “fair
market value” of one Share shall be the average for the five trading days immediately prior to the date of determination thereof of the last reported sale price regular way on each such day, or, in the case no such sale takes place on any such
day, the average of the reported closing bid and asked prices regular way of the shares of Common Stock on such day, in each case as quoted on the New York Stock Exchange, as reported by Bloomberg Markets, or such other principal securities exchange
or inter-dealer quotation system on which the shares of Common Stock are then traded. 
 1.5 Delivery of Shares and New
Warrant. Within two (2) business days after Holder exercises this Warrant in the manner set forth in Section 1.2 or Section 1.3 above, the Company shall deliver to Holder the Shares so acquired, provided that such Shares shall be
deemed delivered upon the Company’s delivery of evidence of a book-entry or similar position through The Depository Trust & Closing Corporation or any other depository or similar functionary, credited to an account for the benefit of
Holder. If this Warrant has not been fully exercised and has not expired, then unless otherwise set forth in the Notice of Exercise a new warrant representing the Shares not so acquired shall be issued to Holder. 

1.6 Treatment of Warrant at Acquisition. In the event of an Acquisition, either (a) Holder shall exercise or
convert this Warrant in full (or shall be deemed to so convert pursuant to the immediately following sentence) with respect to all remaining Shares for which the Warrant is then exercisable and such exercise or conversion will be deemed effective
immediately prior to the consummation of such Acquisition or (b) if Holder elects in writing not to exercise or convert the Warrant, this Warrant will expire upon the consummation of such Acquisition. The Company shall provide Holder with
written notice of the foregoing (together with such reasonable information as Holder may request in connection with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior
to the closing of the proposed Acquisition and, unless the Company receives a notice in writing from Holder that it elects to have the unexercised portion of the Warrant expire, then if the Acquisition involves a price per share of Common Stock that
exceeds the Warrant Price the unexercised portion of the Warrant shall be deemed to be automatically exercised pursuant to Section 1.3 immediately prior to the Acquisition. 

  
 2 

 For purposes of this Warrant, “Acquisition” shall mean:
(i) the acquisition of the Company by another entity by means of any transaction or series of related transactions to which the Company is a party (including, without limitation, any stock acquisition, reorganization, merger or consolidation,
but excluding any sale of stock for capital raising purposes and any transaction effected primarily for purposes of changing the Company’s jurisdiction of incorporation) other than a transaction or series of related transactions in which the
holders of the voting securities of the Company outstanding immediately prior to such transaction or series of related transactions retain, immediately after such transaction or series of transactions, at least a majority of the total voting power
represented by the outstanding voting securities of the Company or such other surviving or resulting entity (or if the Company or such other surviving or resulting entity is a wholly-owned subsidiary immediately following such acquisition, its
parent), or (ii) a sale, lease or other disposition of all or substantially all of the assets of the Company and its subsidiaries taken as a whole by means of any transaction or series of related transactions, except where such sale, lease or
other disposition is to a wholly-owned subsidiary or affiliate of the Company. 
 1.7 Replacement of Warrant. On
receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction of this Warrant, upon delivery of an indemnity agreement reasonably satisfactory
in form, substance and amount to the Company or, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company at its expense shall, within a reasonable period of time, execute and deliver to Holder, in lieu of this
Warrant, a new warrant of like tenor and amount. 
 ARTICLE 2 

ADJUSTMENTS TO THE SHARES AND NOTIFICATION OF CERTAIN EVENTS 

2.1 Fractional Shares. No fractional Shares shall be issuable upon exercise of this Warrant and the number of Shares to
be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise of this Warrant, the Company shall eliminate such fractional share interest by paying Holder an amount computed by multiplying the
fractional interest by the fair market value, calculated as provided in Section 1.4 above, of a full Share. 
 2.2
Adjustments. Subject to the expiration of this Warrant pursuant to Section 5.1, the number and kind of shares purchasable hereunder and the Warrant Price therefor are subject to adjustment from time to time, as follows: 

2.2.1 Merger or Reorganization. If at any time there shall be any reorganization, recapitalization,
merger or consolidation (a “Reorganization”) involving the Company (other than an Acquisition which is subject to the provisions of Section 1.6) in which shares of the Company’s stock are converted into or exchanged for
securities, cash or other property, then, as a part of such Reorganization, lawful provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant, the kind and amount of securities, cash or other
property of the successor corporation resulting from such Reorganization, equivalent in value to that which a holder of the Shares deliverable upon exercise of this Warrant would have been entitled in such Reorganization if the right to purchase the
Shares hereunder had been exercised immediately prior to such Reorganization. In any such case, appropriate adjustment (as determined in good faith by the Board of Directors of the successor corporation) shall be made in the application of the
provisions of this Warrant with respect to the rights and interests of the Holder after such Reorganization to the end that the provisions of this Warrant shall be applicable after the event, as near as reasonably may be, in relation to any shares
or other securities deliverable after that event upon the exercise of this Warrant. 
 2.2.2
Reclassification of Shares. If the securities issuable upon exercise of this Warrant are changed into the same or a different number of securities of any other class or classes by reclassification, capital reorganization or otherwise (other
than as otherwise provided for herein) (a “Reclassification”), then, in any such event, in lieu of the number of Shares which the Holder would otherwise have been entitled to receive, the Holder shall have the right thereafter to
exercise this Warrant for a number of shares of such other class or classes of stock that a holder of the number of securities deliverable upon exercise of this Warrant immediately before that change would have been entitled to receive in such
Reclassification (at the same aggregate Warrant Price as would have applied prior to such Reclassification), all subject to further adjustment as provided herein with respect to such other shares. 

  
 3 

 2.2.3 Subdivisions and Combinations. In the event
that the outstanding shares of the Company’s Common Stock are subdivided (by stock split, by payment of a stock dividend or otherwise) into a greater number of shares of such securities, the number of Shares issuable upon exercise of the rights
under this Warrant immediately prior to such subdivision shall, concurrently with the effectiveness of such subdivision, be proportionately increased, and the Warrant Price shall be proportionately decreased, and in the event that the outstanding
shares of Common Stock are combined (by reclassification or otherwise) into a lesser number of shares of such securities, the number of Shares issuable upon exercise of the rights under this Warrant immediately prior to such combination shall,
concurrently with the effectiveness of such combination, be proportionately decreased, and the Warrant Price shall be proportionately increased. 

2.2.4 Adjustment of Warrant Price Upon Issuance of Additional Shares of Common Stock. If at any time or
from time to time prior to February 1, 2019, the Company shall issue or sell any additional shares of Common Stock or Common Stock Equivalents for a consideration per share less than the fair market value (other than Exempt Issuances, which
shall not result in adjustments pursuant to this Section 2.2.4) then, effective on the date specified below, the Warrant Price then in effect shall be reduced to a price (calculated to the nearest
one-hundredth of a cent) determined in accordance with the following formula: 
 WP2 = WP1* (A + B) ÷ (A + C). 

For purposes of the foregoing formula, the following definitions shall apply: 

i) “WP2” shall mean the Warrant Price in
effect immediately after such issuance or deemed issuance of additional shares of Common Stock 
 ii)
“WP1” shall mean the Warrant Price in effect immediately prior to such issuance or deemed issuance of additional shares of Common Stock; 

iii) “A” shall mean the number of shares of Common Stock Deemed Outstanding immediately prior to such
issuance or deemed issuance of additional shares of Common Stock; 
 iv) “B” shall mean the number
of shares of Common Stock Deemed Outstanding that would have been issued if such additional shares of Common Stock had been issued or deemed issued at a price per share equal to WP1 (determined
by dividing the aggregate consideration received by the Company in respect of such issue by WP1); and 

v) “C” shall mean the number of such additional shares of Common Stock issued in such transaction.

 Upon each such adjustment of the Warrant Price hereunder, the number of Shares issuable upon exercise of
this Warrant shall be adjusted to the number of shares of Common Stock determined by multiplying the Warrant Price in effect immediately prior to such adjustment by the number of Shares issuable upon exercise of this Warrant immediately prior to
such adjustment and dividing the product thereof by the Warrant Price resulting from such adjustment. 

“Exempt Issuances” means any issuance of additional shares of Common Stock or Common Stock
Equivalents (a) for which an adjustment is otherwise provided under Section 2.2 hereof, (b) pursuant to the exercise of this Warrant (or any Warrant issued as a replacement for this Warrant or upon the transfer or partial exercise
hereof) in whole or in part, (c) pursuant to the exercise of any Common Stock Equivalents outstanding on the date hereof, (d) pursuant to the issuance of Common Stock or Common Stock Equivalents granted or to be granted under an equity
compensation plan approved by stockholders of the Company or (e) the issuance of shares of Common Stock or Common Stock Equivalents as consideration in connection with the acquisition of all or a controlling interest in another business
(whether by merger, purchase of stock or assets or otherwise) if such issuance is approved by the board of directors of the Company. 

  
 4 

 “The “Common Stock Deemed Outstanding”
means at any given time, the number of shares of Common Stock outstanding at such time, plus the number of shares of Common Stock issuable upon the conversion or exercise of Common Stock Equivalents then-outstanding regardless of whether such
securities are actually exercisable at such time. 
 “Common Stock Equivalents” means evidences of
indebtedness, shares of stock or other securities which are convertible into or exchangeable for, with or without payment of additional consideration, shares of Common Stock, either immediately or upon the arrival of a specified date or the
happening of a specified event or both. 
 2.2.5 No Impairment. The Company shall not, by amendment of
its charter documents or through any consolidation, merger, reorganization, transfer of assets, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of the
Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder against dilution or other impairment. 

2.2.6 Notice of Adjustments. Upon any adjustment in accordance with this Section 2.2, the Company
shall give notice thereof to the Holder, which notice shall state the event giving rise to the adjustment, the Warrant Price as adjusted and the number of securities or other property purchasable upon the exercise of the rights under this Warrant,
setting forth in reasonable detail the method of calculation of each. The Company shall, upon the written request of any Holder, furnish or cause to be furnished to such Holder a certificate setting forth (i) such adjustments, (ii) the
Warrant Price at the time in effect and (iii) the number of securities and the amount, if any, of other property that at the time would be received upon exercise of this Warrant. 

2.3 Notification of Certain Events. Prior to the Expiration Date, in the event that the Company shall authorize: 

2.3.1 the issuance of any dividend or other distribution on the capital stock of the Company (other than
(i) dividends or distributions otherwise provided for in Section 2.2.3, or (ii) any repurchases of the Company’s Common Stock), whether in cash, property, stock or other securities; or 

2.3.2 the voluntary liquidation, dissolution or winding up of the Company, 

the Company shall send to the Holder at least ten (10) days prior written notice of the date on which a record shall be taken for any
such dividend or distribution specified in clause 2.3.1 or the expected effective date of any such other event specified in clause 2.3.2. The notice provisions set forth in this section may be shortened or waived prospectively or retrospectively by
the consent of the Holder.

 INVESTMENT
REPRESENTATIONS AND COVENANTS OF HOLDER 
 With respect to the acquisition of this Warrant and any of the Shares, Holder
hereby represents and warrants to, and agrees with, the Company as follows: 
 4.1 Purchase Entirely for Own Account.
This Warrant is issued to Holder in reliance upon Holder’s representation to the Company that this Warrant and the Shares will be acquired for investment for Holder’s own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof other than to an affiliate, and that Holder has no present intention of selling, granting any participation in, or otherwise distributing the same other than to an affiliate. By executing this Warrant,
Holder further represents that Holder does not have any contract, undertaking, agreement or arrangement with any person, other than an affiliate, to sell, transfer or grant participations to such person or to any third person with respect to any of
the Shares. 
 4.2 Reliance upon Holder’s Representations. Subject to Section 5.12, Holder understands that
this Warrant and the Shares are not registered under the Act on the ground that the issuance of such securities is exempt from registration under the Act, and that the Company’s reliance on such exemption is predicated on Holder’s
representations set forth herein. 
 4.3 Accredited Investor Status. Holder represents to the Company that Holder is
an Accredited Investor (as defined in the Act). 
 4.4 Restricted Securities. Holder understands that this Warrant and
the Shares are “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such federal securities laws and applicable
regulations such securities may be resold without registration under the Act only in certain limited circumstances. 
 4.5
Restrictions on Sale. Notwithstanding anything to the contrary contained herein, Holder agrees 
 that Holder,
together with its affiliates will not sell on any one trading day more than 50,000 Shares obtained from the exercise of this Warrant or other warrants issued on the same issuance date as this Warrant without the prior written consent of the Company.

transferee, and (ii) if requested by Company, an opinion of counsel, reasonably satisfactory to Company, to the effect that such transfer or assignment is in compliance with applicable federal and state securities laws. The Company may issue
stop transfer instructions to its transfer agent in connection with the restrictions in this Section 5.3. 
 5.4
Transfer Procedure. Subject to the provisions of Section 5.3, Holder may transfer all or part of this Warrant to its affiliates, and such affiliate shall then be entitled to all the rights and bound by all of the obligations of Holder
under this Warrant and any related agreements, and the Company shall cooperate fully in ensuring that any stock issued upon exercise of this Warrant is issued in the name of the affiliate that exercises this Warrant. The terms and conditions of this
Warrant shall inure to the benefit of, and be binding upon, the Company and the holder hereof and its respective permitted successors and assigns. Any transferee shall be bound by the obligations and restrictions of this Warrant as if such

shall be entitled to vote or receive dividends or be deemed the holder of Shares or any other securities of the Company which may at any time be issuable upon the exercise hereof for any purpose, nor shall anything contained herein be construed to
confer upon Holder, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to receive notice of meetings, or to receive
dividends or subscription rights or otherwise until this Warrant shall have been exercised as provided herein. 
 5.11
Counterparts; Signatures. This Warrant may be executed in counterparts, all of which together shall constitute one and the same agreement. Any signature page delivered electronically or by facsimile shall be binding to the same extent as an
original signature page with regards to any agreement subject to the terms hereof or any amendment thereto. 
 5.12
Registration Rights. 
 (a) If, at any time after February 1, 2019 where the Holder is not (upon
reasonable advice of counsel) entitled to sell Shares obtained pursuant to this Warrant under Rule 144(b)(1) as a non-affiliate, the Holder will have the right to demand up to two (2) public registrations covering such Shares. Following a
written request from the Holder, the Company will use its commercially reasonable efforts to expeditiously effect (but in any event no later than sixty (60) days after such request) the registration of such Person’s interest in the Warrant
and/or Shares whose holders request participation in such registration under the Securities Act. The Company may not include any other securities in any registration effected pursuant to this Section 5.12(a) (other than additional Shares
obtained through the Warrant or under warrants issued to the Holder or its affiliates) without the prior written consent of the Holder. Notwithstanding the foregoing, to the extent that the Company is not eligible to register shares on a Form S-3 at a given time then the obligations of the Company to file new registration statements for the Holder under this Section 5.12(a) shall be suspended; provided that (x) the Company agrees to promptly
comply with this Section 5.12(a) following any correction of matters leading to such S-3 ineligibility and (y) to the extent that the Company grants registration rights following the date of this
Warrant to any person or entity that does not have similar suspension of obligations or otherwise grants more favorable rights, then the Holder shall be deemed to get the benefit of such more favorable rights and the suspension of obligations set
forth in this sentence shall not apply. For the avoidance of doubt, in no event will a registration effected pursuant to this Section 5.12(a) be an underwritten public offering. 

(b) If, at any time and from time to time, the Company proposes to register any of its shares of Common Stock
under the Securities Act in connection with an underwritten public offering of such shares of Common Stock, then the Company will promptly give notice to the Holder of its intention to do so. Upon the request of the Holder received within ten
(10) days after receipt of any such notice from the Company, the Company will cause the Holder’s interest in the Shares to be registered under the Securities Act and registered or qualified, as the case may be, under any state securities
laws; provided, however, that the obligation to give such notice and to cause such registration shall not apply to any registration (a) on Form S-8 (or any successor form), (b) of solely a dividend
reinvestment plan or (c) for the sole purpose of offering registered securities to another Person in connection with the acquisition of assets or capital stock of such Person or in connection with a merger, consolidation, combination or similar
transaction with such Person. In connection with any underwritten offering of securities on behalf of the Company or any other holders of the Company’s capital stock, the Company is not required to include any interest in the Warrant or Shares
held by the Holder unless the Holder agrees to the reasonable and customary terms of the underwriting; provided, however, that the total indemnification or other liability of the Holder thereunder shall be limited to the aggregate net cash proceeds
received by the Holder from the sale of the Holder’s interest in the Shares in such offering. The Company will include in any registration effected pursuant to this Section 5.12(b) (i) first, securities offered to be sold by the
Company and by any holder of demand registration rights that is exercising such rights in connection with such registration, (ii) second, any interest in the Shares of the Holder requesting piggyback registration rights hereunder, in each case pro
rata based on the number of Shares issued or issuable under the Warrant thereby (in such quantity as will not, in the written opinion of the underwriters, jeopardize the success of the offering), and (iii) third, any other securities requested to be
included in such registration (in such quantity as will not, in the written opinion of the underwriters, jeopardize the success of the offering). 

  
 8 

 (c) The Company will pay all Registration Expenses in
connection with all registrations (which, for purposes of this Section 5.12, shall include any qualifications, notifications and exemptions) under this Section 5.12. “Registration Expenses” means all expenses incident to
the Company’s performance of or compliance with Section 5.12, including, without limitation, all registration and filing fees (including fees of the SEC a national stock exchange or national securities market), all fees and expenses of
complying with state securities or blue sky laws, all word processing, duplicating and printing expenses, messenger and delivery expenses, the fees and disbursements of counsel for the Company and of its independent public accountants, including the
expenses of any special audits or “cold comfort” letters in underwritten offerings required by or incident to such performance and compliance, the reasonable fees and disbursements of the Holder’s counsel not to exceed $20,000 for any
registration statement and any fees and disbursements of underwriters customarily paid by issuers or sellers of securities, but excluding underwriting discounts and commissions and transfer taxes, if any.

[HOLDER] (the “Warrant”). 
 1. The undersigned hereby elects to purchase
                     shares of the Common Stock of Quantum Corporation pursuant to the terms of the Warrant. [As the Warrant is not fully
exercised and has not expired, the Company will issue to Holder a new warrant representing the Shares not acquired. - IF APPLICABLE AND IF THE ELECTION NOT TO RECEIVE A NEW WARRANT DESCRIBED IN THE FIRST SENTENCE OF PARAGRAPH 3 DOES NOT APPLY]

 2. [IF APPLICABLE - The undersigned elects to make a Cashless Exercise (as such term is defined in the Warrant) in the
manner detailed in Section 1.3 of the Warrant.] 
 3. [The Warrant shall remain in full force and

 ARTICLE 1  

EXERCISE 

1.1 Conditions to Exercise. 

(a) This Warrant shall be exercisable for 900,045 shares of the Company’s Common Stock (subject to
adjustment as provided herein) in whole or in part at any time on or after February 1, 2019 until the Expiration Date. 

(b) The exercise price for each share of Common Stock receivable hereunder shall be the lower of (x)
$2.40 (as adjusted per Article 2) and (y) as determined on February 1, 2019 the lowest of the 5-day volume-weighted average closing prices of the Company’s common stock for the last 5 trading
days in the months of September 2018, October 2018, November 2018, December 2018 and January 2019. 
 (c) To
the extent that the Company has Paid in Full (as defined in the Credit Agreement) in cash all of the Obligations (as defined in the Credit Agreement) under the Credit Agreement on or prior to October 31, 2018, then Quantum shall have the right
to buy back all or any portion of the Warrant, for a price of $.001 per share multiplied by the Shares issuable under the portion of the Warrant being repurchased, and the Warrant would only be exercisable for such reduced amount as of
February 1, 2019 until the Expiration Date. In order to exercise such repurchase right (if applicable), the Company must have given notice to the Holder on or prior to December 31, 2018. 

 1.2 Method of Exercise. Holder may exercise any portion of this
Warrant that is exercisable by delivering a duly completed and executed Notice of Exercise in substantially the form attached as Appendix 1 to the principal office of the Company. Unless Holder is exercising the cashless exercise right set forth in
Section 1.3, Holder shall also deliver to the Company a check, wire transfer (to an account designated in writing by the Company), or other form of payment acceptable to the Company for the aggregate Warrant Price for the Shares being
purchased. 
 1.3 Cashless Exercise Right. In lieu of exercising this Warrant as specified in Section 1.2, Holder
may from time to time, in its sole discretion, exercise this Warrant in whole or in part as to the portion of the Warrant that is exercisable and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon such exercise
for the aggregate Warrant Price pursuant to Section 1.2, elect instead to receive upon such exercise the “net number” of shares of Common Stock determined according to the following formula (a “Cashless Exercise”):

  

							
	X	  	 =
	  	         Y (A - B)        
	  	
		  		  	               A
	  	

 Where: 

 

					
	 X
	  	 =
	  	 The number of Shares to be issued to Holder

			
	 Y
	  	 =
	  	 The number of Shares being exercised under this Warrant or, if only a portion of the Warrant is being exercised, the
portion of the Warrant being canceled (at the date of such calculation)

			
	 A
	  	 =
	  	 The fair market value of one Share (at the date of such calculation)

			
	 B
	  	 =
	  	 The Warrant Price per share (as adjusted to the date of such calculation)

 1.4 Calculation of FMV. For purposes of the calculation above, the “fair
market value” of one Share shall be the average for the five trading days immediately prior to the date of determination thereof of the last reported sale price regular way on each such day, or, in the case no such sale takes place on any such
day, the average of the reported closing bid and asked prices regular way of the shares of Common Stock on such day, in each case as quoted on the New York Stock Exchange, as reported by Bloomberg Markets, or such other principal securities exchange
or inter-dealer quotation system on which the shares of Common Stock are then traded. 
 1.5 Delivery of Shares and New
Warrant. Within two (2) business days after Holder exercises this Warrant in the manner set forth in Section 1.2 or Section 1.3 above, the Company shall deliver to Holder the Shares so acquired, provided that such Shares shall be
deemed delivered upon the Company’s delivery of evidence of a book-entry or similar position through The Depository Trust & Closing Corporation or any other depository or similar functionary, credited to an account for the benefit of
Holder. If this Warrant has not been fully exercised and has not expired, then unless otherwise set forth in the Notice of Exercise a new warrant representing the Shares not so acquired shall be issued to Holder. 

1.6 Treatment of Warrant at Acquisition. In the event of an Acquisition, either (a) Holder shall exercise or
convert this Warrant in full (or shall be deemed to so convert pursuant to the immediately following sentence) with respect to all remaining Shares for which the Warrant is then exercisable and such exercise or conversion will be deemed effective
immediately prior to the consummation of such Acquisition or (b) if Holder elects in writing not to exercise or convert the Warrant, this Warrant will expire upon the consummation of such Acquisition. The Company shall provide Holder with
written notice of the foregoing (together with such reasonable information as Holder may request in connection with such contemplated Acquisition giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior
to the closing of the proposed Acquisition and, unless the Company receives a notice in writing from Holder that it elects to have the unexercised portion of the Warrant expire, then if the Acquisition involves a price per share of Common Stock that
exceeds the Warrant Price the unexercised portion of the Warrant shall be deemed to be automatically exercised pursuant to Section 1.3 immediately prior to the Acquisition. 

  
 2 

 For purposes of this Warrant, “Acquisition” shall mean:
(i) the acquisition of the Company by another entity by means of any transaction or series of related transactions to which the Company is a party (including, without limitation, any stock acquisition, reorganization, merger or consolidation,
but excluding any sale of stock for capital raising purposes and any transaction effected primarily for purposes of changing the Company’s jurisdiction of incorporation) other than a transaction or series of related transactions in which the
holders of the voting securities of the Company outstanding immediately prior to such transaction or series of related transactions retain, immediately after such transaction or series of transactions, at least a majority of the total voting power
represented by the outstanding voting securities of the Company or such other surviving or resulting entity (or if the Company or such other surviving or resulting entity is a wholly-owned subsidiary immediately following such acquisition, its
parent), or (ii) a sale, lease or other disposition of all or substantially all of the assets of the Company and its subsidiaries taken as a whole by means of any transaction or series of related transactions, except where such sale, lease or
other disposition is to a wholly-owned subsidiary or affiliate of the Company. 
 1.7 Replacement of Warrant. On
receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction of this Warrant, upon delivery of an indemnity agreement reasonably satisfactory
in form, substance and amount to the Company or, in the case of mutilation, upon surrender and cancellation of this Warrant, the Company at its expense shall, within a reasonable period of time, execute and deliver to Holder, in lieu of this
Warrant, a new warrant of like tenor and amount. 
 ARTICLE 2 

ADJUSTMENTS TO THE SHARES AND NOTIFICATION OF CERTAIN EVENTS 

2.1 Fractional Shares. No fractional Shares shall be issuable upon exercise of this Warrant and the number of Shares to
be issued shall be rounded down to the nearest whole Share. If a fractional share interest arises upon any exercise of this Warrant, the Company shall eliminate such fractional share interest by paying Holder an amount computed by multiplying the
fractional interest by the fair market value, calculated as provided in Section 1.4 above, of a full Share. 
 2.2
Adjustments. Subject to the expiration of this Warrant pursuant to Section 5.1, the number and kind of shares purchasable hereunder and the Warrant Price therefor are subject to adjustment from time to time, as follows: 

2.2.1 Merger or Reorganization. If at any time there shall be any reorganization, recapitalization,
merger or consolidation (a “Reorganization”) involving the Company (other than an Acquisition which is subject to the provisions of Section 1.6) in which shares of the Company’s stock are converted into or exchanged for
securities, cash or other property, then, as a part of such Reorganization, lawful provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant, the kind and amount of securities, cash or other
property of the successor corporation resulting from such Reorganization, equivalent in value to that which a holder of the Shares deliverable upon exercise of this Warrant would have been entitled in such Reorganization if the right to purchase the
Shares hereunder had been exercised immediately prior to such Reorganization. In any such case, appropriate adjustment (as determined in good faith by the Board of Directors of the successor corporation) shall be made in the application of the
provisions of this Warrant with respect to the rights and interests of the Holder after such Reorganization to the end that the provisions of this Warrant shall be applicable after the event, as near as reasonably may be, in relation to any shares
or other securities deliverable after that event upon the exercise of this Warrant. 
 2.2.2
Reclassification of Shares. If the securities issuable upon exercise of this Warrant are changed into the same or a different number of securities of any other class or classes by reclassification, capital reorganization or otherwise (other
than as otherwise provided for herein) (a “Reclassification”), then, in any such event, in lieu of the number of Shares which the Holder would otherwise have been entitled to receive, the Holder shall have the right thereafter to
exercise this Warrant for a number of shares of such other class or classes of stock that a holder of the number of securities deliverable upon exercise of this Warrant immediately before that change would have been entitled to receive in such
Reclassification (at the same aggregate Warrant Price as would have applied prior to such Reclassification), all subject to further adjustment as provided herein with respect to such other shares. 

  
 3 

 2.2.3 Subdivisions and Combinations. In the event
that the outstanding shares of the Company’s Common Stock are subdivided (by stock split, by payment of a stock dividend or otherwise) into a greater number of shares of such securities, the number of Shares issuable upon exercise of the rights
under this Warrant immediately prior to such subdivision shall, concurrently with the effectiveness of such subdivision, be proportionately increased, and the Warrant Price shall be proportionately decreased, and in the event that the outstanding
shares of Common Stock are combined (by reclassification or otherwise) into a lesser number of shares of such securities, the number of Shares issuable upon exercise of the rights under this Warrant immediately prior to such combination shall,
concurrently with the effectiveness of such combination, be proportionately decreased, and the Warrant Price shall be proportionately increased. 

2.2.4 Adjustment of Warrant Price Upon Issuance of Additional Shares of Common Stock. If at any time or
from time to time prior to February 1, 2019, the Company shall issue or sell any additional shares of Common Stock or Common Stock Equivalents for a consideration per share less than the fair market value (other than Exempt Issuances, which
shall not result in adjustments pursuant to this Section 2.2.4) then, effective on the date specified below, the Warrant Price then in effect shall be reduced to a price (calculated to the nearest
one-hundredth of a cent) determined in accordance with the following formula: 

WP2 = WP1* (A + B) ÷ (A + C). 

For purposes of the foregoing formula, the following definitions shall apply: 

i) “WP2” shall mean the Warrant Price in
effect immediately after such issuance or deemed issuance of additional shares of Common Stock 
 ii)
“WP1” shall mean the Warrant Price in effect immediately prior to such issuance or deemed issuance of additional shares of Common Stock; 

iii) “A” shall mean the number of shares of Common Stock Deemed Outstanding immediately prior to such
issuance or deemed issuance of additional shares of Common Stock; 
 iv) “B” shall mean the number
of shares of Common Stock Deemed Outstanding that would have been issued if such additional shares of Common Stock had been issued or deemed issued at a price per share equal to WP1 (determined
by dividing the aggregate consideration received by the Company in respect of such issue by WP1); and 

v) “C” shall mean the number of such additional shares of Common Stock issued in such transaction.

 Upon each such adjustment of the Warrant Price hereunder, the number of Shares issuable upon exercise of
this Warrant shall be adjusted to the number of shares of Common Stock determined by multiplying the Warrant Price in effect immediately prior to such adjustment by the number of Shares issuable upon exercise of this Warrant immediately prior to
such adjustment and dividing the product thereof by the Warrant Price resulting from such adjustment. 

“Exempt Issuances” means any issuance of additional shares of Common Stock or Common Stock
Equivalents (a) for which an adjustment is otherwise provided under Section 2.2 hereof, (b) pursuant to the exercise of this Warrant (or any Warrant issued as a replacement for this Warrant or upon the transfer or partial exercise
hereof) in whole or in part, (c) pursuant to the exercise of any Common Stock Equivalents outstanding on the date hereof, (d) pursuant to the issuance of Common Stock or Common Stock Equivalents granted or to be granted under an equity
compensation plan approved by stockholders of the Company or (e) the issuance of shares of Common Stock or Common Stock Equivalents as consideration in connection with the acquisition of all or a controlling interest in another business
(whether by merger, purchase of stock or assets or otherwise) if such issuance is approved by the board of directors of the Company. 

  
 4 

 “The “Common Stock Deemed Outstanding”
means at any given time, the number of shares of Common Stock outstanding at such time, plus the number of shares of Common Stock issuable upon the conversion or exercise of Common Stock Equivalents then-outstanding regardless of whether such
securities are actually exercisable at such time. 
 “Common Stock Equivalents” means evidences of
indebtedness, shares of stock or other securities which are convertible into or exchangeable for, with or without payment of additional consideration, shares of Common Stock, either immediately or upon the arrival of a specified date or the
happening of a specified event or both. 
 2.2.5 No Impairment. The Company shall not, by amendment of
its charter documents or through any consolidation, merger, reorganization, transfer of assets, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of the
Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder against dilution or other impairment. 

2.2.6 Notice of Adjustments. Upon any adjustment in accordance with this Section 2.2, the Company
shall give notice thereof to the Holder, which notice shall state the event giving rise to the adjustment, the Warrant Price as adjusted and the number of securities or other property purchasable upon the exercise of the rights under this Warrant,
setting forth in reasonable detail the method of calculation of each. The Company shall, upon the written request of any Holder, furnish or cause to be furnished to such Holder a certificate setting forth (i) such adjustments, (ii) the
Warrant Price at the time in effect and (iii) the number of securities and the amount, if any, of other property that at the time would be received upon exercise of this Warrant. 

2.3 Notification of Certain Events. Prior to the Expiration Date, in the event that the Company shall authorize: 

2.3.1 the issuance of any dividend or other distribution on the capital stock of the Company (other than
(i) dividends or distributions otherwise provided for in Section 2.2.3, or (ii) any repurchases of the Company’s Common Stock), whether in cash, property, stock or other securities; or 

2.3.2 the voluntary liquidation, dissolution or winding up of the Company, 

the Company shall send to the Holder at least ten (10) days prior written notice of the date on which a record shall be taken for any
such dividend or distribution specified in clause 2.3.1 or the expected effective date of any such other event specified in clause 2.3.2. The notice provisions set forth in this section may be shortened or waived prospectively or retrospectively by
the consent of the Holder.

 INVESTMENT
REPRESENTATIONS AND COVENANTS OF HOLDER 
 With respect to the acquisition of this Warrant and any of the Shares, Holder
hereby represents and warrants to, and agrees with, the Company as follows: 
 4.1 Purchase Entirely for Own Account.
This Warrant is issued to Holder in reliance upon Holder’s representation to the Company that this Warrant and the Shares will be acquired for investment for Holder’s own account, not as a nominee or agent, and not with a view to the
resale or distribution of any part thereof other than to an affiliate, and that Holder has no present intention of selling, granting any participation in, or otherwise distributing the same other than to an affiliate. By executing this Warrant,
Holder further represents that Holder does not have any contract, undertaking, agreement or arrangement with any person, other than an affiliate, to sell, transfer or grant participations to such person or to any third person with respect to any of
the Shares. 
 4.2 Reliance upon Holder’s Representations. Subject to Section 5.12, Holder understands that
this Warrant and the Shares are not registered under the Act on the ground that the issuance of such securities is exempt from registration under the Act, and that the Company’s reliance on such exemption is predicated on Holder’s
representations set forth herein. 
 4.3 Accredited Investor Status. Holder represents to the Company that Holder is
an Accredited Investor (as defined in the Act). 
 4.4 Restricted Securities. Holder understands that this Warrant and
the Shares are “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such federal securities laws and applicable
regulations such securities may be resold without registration under the Act only in certain limited circumstances. 
 4.5
Restrictions on Sale. Notwithstanding anything to the contrary contained herein, Holder agrees that Holder, together with its affiliates will not sell on any one trading day more than 50,000 Shares obtained from the exercise of this Warrant
or other warrants issued on the same issuance date as this Warrant without the prior written consent of the Company.

 5.3 Compliance with Securities Laws on Transfer. Without limitation
of Section 5.12, this Warrant and the Shares issuable upon exercise of this Warrant may not be transferred or assigned in whole or in part without (i) compliance with applicable federal and state securities laws by the transferor and the
transferee, and (ii) if requested by Company, an opinion of counsel, reasonably satisfactory to Company, to the effect that such transfer or assignment is in compliance with applicable federal and state securities laws. The Company may issue
stop transfer instructions to its transfer agent in connection with the restrictions in this Section 5.3. 
 5.4
Transfer Procedure. Subject to the provisions of Section 5.3, Holder may transfer all or part of this Warrant to its affiliates, and such affiliate shall then be entitled to all the rights and bound by all of the obligations of Holder
under this Warrant and any related agreements, and the Company shall cooperate fully in ensuring that any stock issued upon exercise of this Warrant is issued in the name of the affiliate that exercises this Warrant. The terms and conditions of this
Warrant shall inure to the benefit of, and be binding upon, the Company and the holder hereof and its respective permitted successors and assigns. Any transferee shall be bound by the obligations and restrictions of this Warrant as if such

shall be entitled to vote or receive dividends or be deemed the holder of Shares or any other securities of the Company which may at any time be issuable upon the exercise hereof for any purpose, nor shall anything contained herein be construed to
confer upon Holder, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to receive notice of meetings, or to receive
dividends or subscription rights or otherwise until this Warrant shall have been exercised as provided herein. 
 5.11
Counterparts; Signatures. This Warrant may be executed in counterparts, all of which together shall constitute one and the same agreement. Any signature page delivered electronically or by facsimile shall be binding to the same extent as an
original signature page with regards to any agreement subject to the terms hereof or any amendment thereto. 
 5.12
Registration Rights. 
 (a) If, at any time after February 1, 2019 where the Holder is not (upon
reasonable advice of counsel) entitled to sell Shares obtained pursuant to this Warrant under Rule 144(b)(1) as a non-affiliate, the Holder will have the right to demand up to two (2) public registrations covering such Shares. Following a
written request from the Holder, the Company will use its commercially reasonable efforts to expeditiously effect (but in any event no later than sixty (60) days after such request) the registration of such Person’s interest in the Warrant
and/or Shares whose holders request participation in such registration under the Securities Act. The Company may not include any other securities in any registration effected pursuant to this Section 5.12(a) (other than additional Shares
obtained through the Warrant or under warrants issued to the Holder or its affiliates) without the prior written consent of the Holder. Notwithstanding the foregoing, to the extent that the Company is not eligible to register shares on a Form S-3 at a given time then the obligations of the Company to file new registration statements for the Holder under this Section 5.12(a) shall be suspended; provided that (x) the Company agrees to promptly
comply with this Section 5.12(a) following any correction of matters leading to such S-3 ineligibility and (y) to the extent that the Company grants registration rights following the date of this
Warrant to any person or entity that does not have similar suspension of obligations or otherwise grants more favorable rights, then the Holder shall be deemed to get the benefit of such more favorable rights and the suspension of obligations set
forth in this sentence shall not apply. For the avoidance of doubt, in no event will a registration effected pursuant to this Section 5.12(a) be an underwritten public offering. 

(b) If, at any time and from time to time, the Company proposes to register any of its shares of Common Stock
under the Securities Act in connection with an underwritten public offering of such shares of Common Stock, then the Company will promptly give notice to the Holder of its intention to do so. Upon the request of the Holder received within ten
(10) days after receipt of any such notice from the Company, the Company will cause the Holder’s interest in the Shares to be registered under the Securities Act and registered or qualified, as the case may be, under any state securities
laws; provided, however, that the obligation to give such notice and to cause such registration shall not apply to any registration (a) on Form S-8 (or any successor form), (b) of solely a dividend
reinvestment plan or (c) for the sole purpose of offering registered securities to another Person in connection with the acquisition of assets or capital stock of such Person or in connection with a merger, consolidation, combination or similar
transaction with such Person. In connection with any underwritten offering of securities on behalf of the Company or any other holders of the Company’s capital stock, the Company is not required to include any interest in the Warrant or Shares
held by the Holder unless the Holder agrees to the reasonable and customary terms of the underwriting; provided, however, that the total indemnification or other liability of the Holder thereunder shall be limited to the aggregate net cash proceeds
received by the Holder from the sale of the Holder’s interest in the Shares in such offering. The Company will include in any registration effected pursuant to this Section 5.12(b) (i) first, securities offered to be sold by the
Company and by any holder of demand registration rights that is exercising such rights in connection with such registration, (ii) second, any interest in the Shares of the Holder requesting piggyback registration rights hereunder, in each case pro
rata based on the number of Shares issued or issuable under the Warrant thereby (in such quantity as will not, in the written opinion of the underwriters, jeopardize the success of the offering), and (iii) third, any other securities requested to be
included in such registration (in such quantity as will not, in the written opinion of the underwriters, jeopardize the success of the offering). 

  
 8 

 (c) The Company will pay all Registration Expenses in
connection with all registrations (which, for purposes of this Section 5.12, shall include any qualifications, notifications and exemptions) under this Section 5.12. “Registration Expenses” means all expenses incident to
the Company’s performance of or compliance with Section 5.12, including, without limitation, all registration and filing fees (including fees of the SEC a national stock exchange or national securities market), all fees and expenses of
complying with state securities or blue sky laws, all word processing, duplicating and printing expenses, messenger and delivery expenses, the fees and disbursements of counsel for the Company and of its independent public accountants, including the
expenses of any special audits or “cold comfort” letters in underwritten offerings required by or incident to such performance and compliance, the reasonable fees and disbursements of the Holder’s counsel not to exceed $20,000 for any
registration statement and any fees and disbursements of underwriters customarily paid by issuers or sellers of securities, but excluding underwriting discounts and commissions and transfer taxes, if any.

 APPENDIX I  

NOTICE OF EXERCISE 

Reference is made to that certain Warrant to Purchase Stock, dated September 30, 2018, issued by Quantum Corporation to
