This INVESTMENT COMMITMENT AGREEMENT (this “Agreement”), dated as of March 16, 2022, is made by and between Quantum Corporation, a Delaware corporation (the “Company”), and each purchaser identified in Schedule II hereto (each, including its permitted successors and assigns, an “Investor” and collectively, the “Investors”).

WHEREAS, the Company proposes to conduct a rights offering by distributing, at no charge, non-transferable rights (the “Rights”) to purchase shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”) to (i) each holder of record of shares of Common Stock and (ii) holders of certain warrants the Company issued on December 27, 2018 and June 16, 2020 listed on Schedule I (the “Participating Warrants”), in each case, as of 5:00 p.m. (New York time) on March 25, 2022 (the “Record Date”), pro rata to such eligible holders based on each such holder’s ownership of shares of Common Stock and/or Participating Warrants;

WHEREAS, the Rights will be exercisable for approximately 30,000,000 shares, subject to adjustment for the number of actual shares, including shares issuable upon exercise of the Participating Warrants, outstanding as of Record Date (the “Offered Shares”) resulting in gross proceeds to the Company of up to sixty-seven million, five hundred thousand dollars ($67,500,000);

WHEREAS, following the distribution of the Rights, the Company will commence an offering registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to which each holder of a Right will be entitled to subscribe for the following (the “Rights Offering”): for each share of Common Stock (including shares of Common Stock issuable upon exercise of the Participating Warrants) held on the Record Date, (i) the right (the “Basic Subscription Right”) to purchase approximately 0.422572999 of a share of Common Stock, at a subscription price of $2.25 per whole share of Common Stock (the “Subscription Price”) and (ii) if the Rights Offering is not fully subscribed and such holder of Rights has exercised its Basic Subscription Rights in full, the right (the “Over-Subscription Privilege”) to purchase additional shares of Common Stock that were not subscribed for by other holders of Rights, which will be allocated proportionately to holders who exercise their Over-Subscription Privileges based on the number of shares each holder subscribed for under the Basic Subscription Right relative to the number of shares subscribed for by all other holders under their Basic Subscription Rights, with the proration process being repeated until all shares have been allocated;

WHEREAS, each Investor has agreed to exercise all of its Basic Subscription Rights in full (the “Basic Shares”);

WHEREAS, in order to facilitate the Rights Offering, upon the terms and subject to the conditions set forth herein, each Investor has agreed to exercise their Basic Subscription Right, and certain of the Investors have agreed to exercise their Over-Subscription Privilege to purchase at the Subscription Price (together, the “Investment Commitment”) shares of Common Stock that are not purchased pursuant to the exercise of Basic Subscription Rights in the Rights Offering up to, but not in excess of, the amount set forth opposite such Investor’s name on Schedule II hereto (or with respect to the Neuberger Investors (as defined in Schedule II below) when taken together with the Neuberger Advisory Investors (as defined herein), the aggregate limit set forth in Schedule II) (together with the Basic Shares, the “Investment Shares”), subject to pro rata cutback or adjustment as described in Section 2(b) and subject further to the maximum percentage ownership as set forth opposite such Investor’s name on Schedule II hereto (the “Cap”);

WHEREAS, in order to facilitate the Rights Offering, upon the terms and subject to the conditions set forth herein, Neuberger Berman Investment Advisers LLC (“Neuberger”) has agreed to use it commercially reasonable efforts to procure that certain other investors advised by Neuberger and holding, as of the date hereof, an aggregate of 3,772,129 shares of Common Stock (the “Neuberger Advisory Investors”), also exercise their Basic Subscription Rights and Over-Subscription Privilege subject to pro rata cutback or adjustment as described in Section 2(b) and subject further, when taken together with the Neuberger Investors, to the Cap; and

WHEREAS, the Board of Directors of the Company has approved the Rights Offering, this Agreement and the transactions contemplated hereby.

NOW, THEREFORE, in consideration of the mutual promises, agreements, representations, warranties and covenants contained herein, each of the parties hereto hereby agrees as follows:

(a) As soon as practicable after the execution hereof, the Company shall publicly announce its plans to conduct the Rights Offering, including disclosing the Record Date, the material terms of the Rights Offering, the anticipated closing date and the Investors’ Investment Commitment hereunder.

(b) The Company shall use commercially reasonable efforts to: (i) initiate the Rights Offering, on the terms set forth above, within five business days after the Record Date, and (ii) close the Rights Offering by no later than 5:00 p.m. (New York time) on April 30, 2022.

(a) Each Investor agrees, promptly after the Rights Offering is initiated by the Company, but in no event later than the expiration date of the Rights Offering, to exercise (i) all of its Basic Subscription Rights in full and (ii) its Over-Subscription Privilege, each in the amounts as set forth on Schedule II hereto (subject to proration or adjustment as described in Section 2(b) below and the payment date specified in Section 2(c) and 2(d) below, as applicable), in the case of each Investor, not to exceed the Cap specified for such Investor (or with respect to the Neuberger Investors, the aggregate limit in respect of such Neuberger Investors and the Neuberger Advisory Investors taken together or on a basis as determined by Neuberger). In addition, Neuberger will use it commercially reasonable efforts, which may include, as appropriate, recommendations, to procure that the Neuberger Advisory Investors exercise (i) all of their Basic Subscription Rights in full and (ii) their Over-Subscription Privilege (subject to proration or adjustment as described in Section 2(b) below and the payment date specified in Section 2(c) and 2(d) below, as and if applicable) and not to exceed the Cap specified for the Neuberger Investors (in aggregate limit in respect of such Neuberger Advisory Investors and the Neuberger Investors or on a basis as determined by Neuberger).

2

(b) The Over-Subscription Privilege shall be subject to proration to ensure that the aggregate proceeds raised in the Rights Offering do not exceed the maximum offering amount thereof. If an insufficient number of shares of Common Stock is available to fully satisfy all exercises of Over-Subscription Privileges, the available shares of Common Stock will be allocated proportionately among the holders of Common Stock and Participating Warrants (and, in each case with respect to the Investors, inclusive of any of their assignees or designees pursuant to the terms hereof) who exercised their Basic Subscription Rights in full and who have elected to exercise their Over-Subscription Privileges based on the number of shares each such holder subscribed for in the aggregate under the Basic Subscription Right relative to the number of shares subscribed for by all other such holders under their Basic Subscription Rights. If this pro rata allocation results in any holder receiving a greater number of shares of Common Stock than the holder subscribed for pursuant to the exercise of the Over-Subscription Privileges, then such holder will be allocated only that number of shares of Common Stock for which the holder oversubscribed, and the remaining shares will be allocated among all other holders exercising the Over-Subscription Privileges on the same pro rata basis described above. The proration process will be repeated until all shares of Common Stock under the Rights Offering have been allocated. Any fractional shares to which persons exercising their Over-Subscription Privileges would otherwise be entitled pursuant to such allocation shall be rounded down to the nearest whole share. Notwithstanding anything in this Agreement to the contrary, and in addition to the limitations set forth above, in no event shall any Investor’s shares of the Common Stock (including shares of Common Stock issuable upon conversion of any outstanding warrants of the Company, inclusive of an anti-dilution adjustments applicable thereto as a result of the Rights Offering) beneficially owned by such Investor and its affiliates immediately following the Closing, exceed the lower of the Cap set forth opposite such Investor’s name on Schedule II hereto and 34.99%, in each case of the Company’s issued and outstanding shares of Common Stock outstanding on an actual basis following the Closing (after giving effect to the conversion of any outstanding warrants held by any such Investor and its affiliates, inclusive of any anti-dilution adjustments applicable thereto as a result of the Rights Offering) (which Cap, for the avoidance of doubt, shall be measured on a per Investor basis and exclusive of any affiliates of such Investor in the case of OC II FIE V LP and OC III LVS XL LP), and the Company agrees that, pursuant to the Rights Offering or this Agreement, Basic Subscription Rights and/or Over-Subscription Privilege shall be deemed reduced as necessary to the extent of such excess and all funds delivered by the Investor in respect of such excess shares shall be returned thereto. For the purposes of this clause 2(b), the Neuberger Investors and Neuberger Advisory Investors will be treated as a single Investor.

(c) Promptly after the Rights Offering is initiated by the Company, but in no event later than the expiration date thereof, each Investor shall deliver to the subscription agent a properly completed and executed rights certificate and related subscription documents in respect of the shares subject to the Basic Subscription Rights and the Over-Subscription Privileges being exercised pursuant to Section 2(a), together with payment in an amount necessary to purchase such Investment Shares subject to the Basic Subscription Rights and Over-Subscription Privileges, each in accordance with the documentation requested by the subscription agent in connection with the Rights Offering; provided that each of OC II FIE V LP (“OC II”), OC III LVS XL LP (together with OC II, the “OC Investors”), and Neuberger Investors and Neuberger Advisory Investors (collectively with the OC Investors, the “Over-Subscribing Investors”) shall be required to make payment for the Basic Subscription Rights in accordance with this Section 2(c) and solely with respect to their Over-Subscription Privileges, in accordance with Section 2(d).

3

(d) Solely with respect to the Over-Subscribing Investors, as promptly as practicable following the expiration date of the Rights Offering, the Company shall deliver to each Over-Subscribing Investor a notice (the “Backstop Notice”) setting forth the number of shares as to which the Basic Subscription Rights have been exercised by all holders of Company shares of Common Stock and Participating Warrants, including the Investors, the proration calculations in respect of the Over-Subscription Privileges exercised by all such holders, including the Investors, and the amount of shares of Common Stock constituting each Over-Subscribing Investor’s Over-Subscription Privilege subject to any required pro-ration, together with the related purchase price for such Over-Subscription Privilege, and each Over-Subscribing Investor shall, subject to the terms hereof, deliver, by wire transfer of immediately available funds to an account designated by the subscription agent, within two business days after receiving its Backstop Notice, such purchase price covering their Over-Subscription Privilege at the Subscription Price per whole share.

(e) For the avoidance of doubt, the aggregate payment to be paid by each Investor as well as any Neuberger Advisory Investor to the subscription agent pursuant to Sections 2(c) and 2(d) is the product of the aggregate amount of the Investment Shares to be purchased by such person (which shall be, subject to the Backstop Notice, as applicable, and up to but not in excess of the amount set forth on Schedule II hereto opposite such Investor’s name, and subject further to the Cap) multiplied by the Subscription Price. The Company shall use commercially reasonable efforts to cause the closing of the Rights Offering (the “Closing”) to occur within five business days (such date, the “Closing Date”) following the expiration of the offering period of the Rights Offering (the “Expiration Time”), subject to the satisfaction or waiver of the conditions precedent set forth in Section 6 (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions at such time).

(f) Notwithstanding anything in this Agreement to the contrary, for purposes of clarity, if an Oversubscribing Investor’s beneficial ownership changes (which ownership, for the avoidance of doubt, shall be a minimum amount entitling each Oversubscribing Investor to at least one Basic Share) during the period from the date of this Agreement to the Record Date, such Oversubscribing Investor’s exercise of its Over-Subscription Privilege hereunder will be respectively adjusted such that the Oversubscribing Investor will be required to purchase an amount of shares of Common Stock in the Rights Offering (subject to pro rata cutback or adjustment as described in Section 2(b)) up to, but not in excess of, the Cap.
