 EXECUTION COPY 
 AGREEMENT 

This Agreement (this “Agreement”) is made and entered into as of May 13, 2013, by and among Quantum Corporation, a
Delaware corporation (the “Company”), and the entities and natural persons listed on Exhibit A hereto and their respective Affiliates (collectively, “Starboard”) (each of the Company and Starboard, a
“Party” to this Agreement, and collectively, the “Parties”). 
 RECITALS 

WHEREAS, the Company and Starboard have engaged in various discussions and communications concerning the Company’s business, assets
and financial performance; 
 WHEREAS, Starboard is deemed to beneficially own shares of common stock of the Company (the
“Common Stock”) totaling, in the aggregate, 44,243,875 shares, including shares underlying the Company’s convertible senior subordinated notes, or approximately seventeen percent (17.0%) of the Common Stock of the Company
issued and outstanding on the date hereof; and 
 WHEREAS, the Company and Starboard have determined to come to an agreement
with respect to the election of members of the Company’s board of directors (the “Board”) at the 2013 annual meeting of stockholders of the Company (the “2013 Annual Meeting”) and certain other matters, as
provided in this Agreement. 
 NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and
agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto, intending to be legally bound hereby, agree as follows: 

1. Board Matters; Board Appointments; 2013 Annual Meeting. 

(a) The Company agrees that the Board and all applicable committees of the Board shall take all necessary actions, effective immediately
following the execution of this Agreement, to (i) increase the size of the Board from eight (8) members to nine (9) members, and (ii) appoint Jeffrey Smith (“Nominee One”) as a member of the Board. The Company
further agrees that prior to the mailing of its definitive proxy statement for the 2013 Annual Meeting, the Board and all applicable committees of the Board shall take all necessary actions, subject to Section 1(d) and (j) below, to
nominate Louis DiNardo (“Nominee Two”) and Philip Black (“Nominee Three,” and together with Nominee One and Nominee Two, the “Starboard Nominees”) for election to the Board at the 2013 Annual
Meeting. During the Standstill Period (as defined below), the Board and all applicable committees of the Board shall not increase the size of the Board to more than nine (9) directors. 

(b) Upon the execution of this Agreement, Starboard hereby agrees not to (i) nominate any person for election at the 2013 Annual
Meeting, (ii) submit any proposal for consideration at, or bring any other business before, the 2013 Annual Meeting, directly or indirectly, or (iii) initiate, encourage or participate in any “withhold” or similar campaign with
respect to the 2013 Annual Meeting, directly or indirectly, and shall not permit any of its Affiliates or Associates to do any of the items in this Section 1(b). Starboard shall not publicly or privately encourage or support any other
stockholder to take any of the actions described in this Section 1(b). 







 (c) The Company agrees that it will recommend, support and solicit proxies for the election
of the Starboard Nominees at the 2013 Annual Meeting in the same manner as for the Company’s other nominees standing for election to the Board at the 2013 Annual Meeting. 
 (d) The Company agrees that if any of the Starboard Nominees or any Replacement Director (as defined below) is unable to serve as a director, resigns as a director or is removed as a director prior to the
2014 annual meeting of stockholders of the Company (the “2014 Annual Meeting”), and at such time Starboard beneficially owns in the aggregate, excluding shares of Common Stock underlying the Company’s convertible senior
subordinated notes, at least three percent (3.0%) of the Company’s then outstanding Common Stock (subject to adjustment for stock splits, reclassifications, combinations and similar adjustments), Starboard shall have the ability to
recommend a substitute person(s) for approval by the Corporate Governance and Nominating Committee of the Board (the “Governance Committee”), in good faith after exercising its fiduciary duties, which approval shall not be
unreasonably withheld (any such replacement nominee recommended in accordance with the terms of this Section 1(d) shall be referred to as the “Replacement Director”). Any Replacement Director shall (i) other than in the
case of a substitute for Nominee One, be independent of Starboard, (ii) qualify as “independent” pursuant to NYSE listing standards, as do Nominee Two and Nominee Three, and (iii) have relevant financial and business experience.
In the event the Governance Committee does not accept a substitute person recommended by Starboard, Starboard will have the right to recommend additional substitute person(s), who meet the requirements of (i) through (iii) in the preceding
sentence. Upon the recommendation of a Replacement Director nominee by the Governance Committee, the Board shall vote on the appointment of such Replacement Director to the Board no later than five (5) business days after the Governance
Committee recommendation of such Replacement Director; provided, however, that if the Board does not elect such Replacement Director to the Board, the Parties shall continue to follow the procedures of this Section 1(d) until a Replacement
Director is elected to the Board. 
 (e) At the 2013 Annual Meeting, Starboard agrees to appear in person or by proxy at the
2013 Annual Meeting and vote all shares of Common Stock beneficially owned by it (i) in favor of the election of each of the Company’s nominees for election to the Board (ratably with respect to all nominees) and (ii) and in
accordance with the Board’s recommendation with respect to the Company’s “say-on-pay” proposal, unless Institutional Shareholder Services Inc. recommends otherwise with respect to such “say-on-pay” proposal. 

(f) Starboard agrees that it will cause its Affiliates and Associates to comply with the terms of this Agreement. As used in this
Agreement, the terms “Affiliate” and “Associate” shall have the respective meanings set forth in Rule 12b-2 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended, or the rules
or regulations promulgated thereunder (the “Exchange Act”) and shall include all persons or entities that at any time during the term of this Agreement become Affiliates or Associates of any person or entity referred to in this
Agreement. 
 (g) As of the date of this Agreement, each of Nominee Two and Nominee Three is appointed as an observer to the
Board (the “Board Observers”) until the 2013 Annual Meeting. Each of the Board Observers will (i) receive copies of all notices and written information furnished to the full Board, reasonably in advance of each meeting to the
extent practicable, and (ii) be permitted to be present at all meetings of the full Board (whether by telephone or in person). Notwithstanding the foregoing, (A) the Company shall be entitled to withhold any information and exclude the
Board Observers from any meeting, or any portion thereof, as is reasonably determined by the Company to be necessary to protect the Company’s attorney-client privilege, or as otherwise may be appropriate until the Board Observers are elected to
the Board, and (B) the Board Observers shall execute a confidentiality agreement in form and substance reasonably acceptable to the Company with respect to the information and discussions to which the Board Observers will have access.


  
 2 








 (h) The Company shall use its reasonable best efforts to hold the 2013 Annual Meeting no
later than September 15, 2013. 
 (i) The Company agrees that promptly following the date hereof, but in any event no later
than thirty (30) days from the date hereof, the Board will take all action necessary to cause the appointment of Nominee One to the Leadership and Compensation Committee of the Board. The Company further agrees that promptly following the
conclusion of the 2013 Annual Meeting, but in any event no later than thirty (30) days thereafter, the Board will take all action necessary to cause (i) the appointment of Nominee Two as chairman of the Governance Committee of the Board
and (ii) the appointment of the Nominee Three to the Audit Committee of the Board. 
 (j) Starboard agrees to obtain from
Nominee One an irrevocable resignation letter pursuant to which Nominee One shall resign from the Board and all applicable committees thereof if at any time during the Standstill Period Starboard’s aggregate beneficial ownership of Common
Stock, excluding shares of Common Stock underlying the Company’s convertible senior subordinated notes, decreases to less than three percent (3.0%) of the Company’s then outstanding Common Stock (subject to adjustment for stock
splits, reclassifications and similar adjustments). Also at such time, the right of Starboard pursuant to Section 1(d) to participate in the recommendation of a Replacement Director to fill the vacancy caused by any such resignation of Nominee
One shall automatically terminate. 
 (k) Starboard shall cause each Starboard Nominee (and any Replacement Director) to agree
in writing, during the term of any service as a director of the Company, (i) to comply with all policies, procedures, processes, codes, rules, standards and guidelines applicable to members of the Board, including, without limitation, the
Company’s code of conduct, insider trading policy, its Regulation FD policy, its related party transactions policy and corporate governance guidelines and (ii) to keep confidential and not publicly disclose discussions and matters
considered in meetings of the Board and Board committees, unless previously disclosed publicly by the Company. Each Starboard Nominee (and any Replacement Director), within five (5) business days of appointment to serve as a director, shall
submit to the Company a fully completed copy of the Company’s standard director & officer questionnaire and other reasonable and customary director onboarding documentation required by the Company in connection with the appointment or
election of new Board members. 
 2. Standstill Provisions. 

(a) Starboard agrees that, from the date of this Agreement until the earlier of (i) the date that is fifteen (15) business days
prior to the deadline for the submission of stockholder nominations for the 2014 Annual Meeting pursuant to the Company’s bylaws or (ii) the date that is one hundred (100) days prior to the first anniversary of the 2013 Annual Meeting
(the “Standstill Period”), neither it nor any of its Affiliates or Associates under its control or direction will, and it will cause each of such Affiliates and Associates not to, directly or indirectly, in any manner: 

(i) engage in any solicitation of proxies or consents or become a “participant” in a “solicitation” as such terms
are defined in Regulation 14A under the Exchange Act of proxies or consents (including, without limitation, any solicitation of consents that improperly seeks to call a special meeting of stockholders), in each case, with respect to securities of
the Company; 
 (ii) form, join or in any way participate in any “group” (within the meaning of Section 13(d)(3)
of the Exchange Act) with respect to the Common Stock (other than a “group” that includes all or some of the persons identified on Exhibit A, but does not include any other entities or persons not identified on Exhibit A as
of the date hereof); provided, however, that nothing herein shall 

  
 3 








 
limit the ability of an Affiliate of Starboard to join the “group” following the execution of this Agreement, so long as any such Affiliate agrees to be bound by the terms and
conditions of this Agreement; 
 (iii) deposit any Common Stock in any voting trust or subject any Common Stock to any
arrangement or agreement with respect to the voting of any Common Stock, other than any such voting trust, arrangement or agreement solely among the members of Starboard and otherwise in accordance with this Agreement; 

(iv) seek or encourage any person to submit nominations in furtherance of a “contested solicitation” for the election or
removal of directors with respect to the Company or seek, encourage or take any other action with respect to the election or removal of any directors; 
 (v)(A) make any proposal for consideration by stockholders at any annual or special meeting of stockholders of the Company, (B) make any offer or proposal (with or without conditions) with respect to
any merger, acquisition, recapitalization, restructuring, disposition or other business combination involving the Company, or encourage, initiate or support any other third party in any such related activity or (C) make any public communication
in opposition to any Company acquisition or disposition activity approved by the Board; 
 (vi) seek, alone or in concert with
others, representation on the Board, except as specifically contemplated in Section 1; 
 (vii) seek to advise, encourage,
support or influence any person with respect to the voting or disposition of any securities of the Company at any annual or special meeting of stockholders, except in accordance with Section 1; or 

(viii) make any request or submit any proposal to amend the terms of this Agreement other than through non-public communications with
the Company that would not be reasonably determined to trigger public disclosure obligations for any Party. 
 (b) Except as
expressly provided in Section 1 or Section 2(a), each member of Starboard shall be entitled to: 
 (i) vote their
shares on any other proposal duly brought before the 2013 Annual Meeting, or otherwise vote as each member of Starboard determines in its sole discretion; or 
 (ii) disclose, publicly or otherwise, how it intends to vote or act with respect to any securities of the Company, any stockholder proposal or other matter to be voted on by the stockholders of the
Company and the reasons therefore; provided that, as applicable, all such activity is in compliance with the requirements of this Agreement.

designed to produce economic benefits and risks that correspond to the ownership of Common Stock, whether or not any of the foregoing would give rise to beneficial ownership (as determined under Rule 13d-3 promulgated under the Exchange Act), and

 5. Press Release. 

Promptly following the execution of this Agreement, the Company and Starboard shall jointly


  
 5 








 
issue a mutually agreeable press release (the “Mutual Press Release”) announcing certain terms of this Agreement, in the form attached hereto as Exhibit B. Prior to the
issuance of the Mutual Press Release, neither the Company nor Starboard shall issue any press release or public announcement regarding this Agreement without the prior written consent of the other Party. Until the 2013 Annual Meeting, neither the
Company nor Starboard or any of the Starboard Nominees shall make any public announcement or statement that is inconsistent with or contrary to the statements made in the Mutual Press Release, except as required by law or the rules of any stock
exchange or with the prior written consent of the other Party. 
 6. Specific Performance. 

Each of Starboard, on the one hand, and the Company, on the other hand, acknowledges and agrees that irreparable injury to the other
party hereto would occur in the event any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that such injury would not be adequately compensable by the remedies available at
law (including the payment of money damages). It is accordingly agreed that Starboard, on the one hand, and the Company, on the other hand (the “Moving Party”), shall each be entitled to specific enforcement of, and injunctive
relief to prevent any violation of, the terms hereof, and the other party hereto will not take action, directly or indirectly, in opposition to the Moving Party seeking such relief on the grounds that any other remedy or relief is available at law
or in equity. This Section 6 is not the exclusive remedy for any violation of this Agreement. 
 7. Expenses.

 The Company shall reimburse Starboard for its reasonable, documented out-of-pocket fees and expenses (including legal
expenses) incurred in connection with the matters related to the 2013 Annual Meeting, the filing of a Schedule 13D amendment in connection with this Agreement and the negotiation and execution of this Agreement, provided that such reimbursement
shall not exceed thirty thousand dollars ($30,000) in the aggregate. 
 8. Severability. 

If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated. It is hereby stipulated and declared to be the
intention of the Parties that the Parties would have executed the remaining terms, provisions, covenants and restrictions without including any of such which may be hereafter declared invalid, void or unenforceable. In addition, the Parties agree to
use their best efforts to agree upon and substitute a valid and enforceable term, provision, covenant or restriction for any of such that is held invalid, void or enforceable by a court of competent jurisdiction. 

9. Notices. 
 Any notices, consents, determinations, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered:

 10. Applicable Law. 
 This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of Delaware without reference to the conflict of laws principles thereof. Each of the Parties hereto
irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations
arising hereunder brought by the other party hereto or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware

 7 








 
in any court other than the aforesaid courts. Each of the Parties hereto hereby irrevocably waives, and agrees not to assert in any action or proceeding with respect to this Agreement,
(i) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason, (ii) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process
commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by applicable legal
requirements, any claim that (A) the suit, action or proceeding in such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper or (C) this Agreement, or the subject matter hereof, may
not be enforced in or by such courts. 
 11. Counterparts. 

This Agreement may be executed in two or more counterparts, each of which shall be considered one and the same agreement and shall become

 12. Entire Agreement; Amendment and Waiver; Successors and Assigns; Third Party Beneficiaries. 
 This Agreement contains the entire understanding of the Parties hereto with respect to its subject matter. There are no restrictions, agreements, promises, representations, warranties, covenants or
undertakings between the Parties other than those expressly set forth herein. No modifications of this Agreement can be made except in writing signed by an authorized representative of each the Company and Starboard, except that the signature of an
authorized representative of the Company will not be required to permit an Affiliate of Starboard to agree to be listed on Exhibit A and be bound by the terms and conditions of this Agreement. No failure on the part of any party to exercise,
and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof or the exercise
of any other right, power or remedy. All remedies hereunder are cumulative and are not exclusive of any other remedies provided by law. The terms and conditions of this Agreement shall be binding upon, inure to the benefit of, and be enforceable by
the Parties hereto and their respective successors, heirs, executors, legal representatives, and permitted assigns. No party shall assign this Agreement or any rights or obligations hereunder without, with respect to any member of Starboard, the
prior written consent of the Company, and with respect to the Company, the prior written consent of Starboard. This Agreement is solely for the benefit of the Parties hereto and is not enforceable by any other persons. 

13. Mutual Non-Disparagement. 
 Subject to applicable law, each of the Parties covenants and agrees that, during the Standstill Period, or if earlier, until such time as the other Party or any of its agents, subsidiaries, affiliates,
successors, assigns, officers, key employees or directors shall have breached this Section, neither it nor any of its respective agents, subsidiaries, affiliates, successors, assigns, officers, key employees or directors, shall in any way publicly
disparage, call into disrepute, or otherwise defame or slander the other Parties or such other Parties’ subsidiaries, affiliates, successors, assigns, officers (including any current officer of a Party or a Parties’ subsidiaries who no
longer serves in such capacity following the execution of this Agreement), directors (including any current director of a Party or a Parties’ subsidiaries who no longer serves in such capacity following the execution of this Agreement),
employees, stockholders, agents, attorneys or representatives, or any of their products or services, in any manner that would 

  
 8 








 
damage the business or reputation of such other Parties, their products or services or their subsidiaries, affiliates, successors, assigns, officers (or former officers), directors (or former
directors), employees, stockholders, agents, attorneys or representatives. For purposes of this Section 13, the Starboard Nominees shall not be deemed to be an agent, affiliate, officer, key employee or director of the Company or
Starboard and no actions taken by any agent or other representative of a Party in any capacity other than as a representative of such Party shall be covered by this Agreement.
