  Directors to grant, indemnification to directors and officers in terms
  sufficiently broad to permit such indemnification under certain circumstances
  for liabilities (including reimbursement for expenses incurred) arising under
  the Securities Act of 1933, as amended (the &#147;Securities Act&#148;). The Registrant&#146;s
  Amended and Restated Certificate of Incorporation contains a provision
  eliminating the personal liability of the Registrant&#146;s directors to the
  Registrant or its stockholders for breach of fiduciary duty as a director to the
  fullest extent permitted by applicable law. The Registrant's Bylaws, as amended,
  provide for the indemnification of its directors, officers, employees and other
  agents to the maximum extent permitted by Delaware General Corporation Law, and
  the Registrant has entered into agreements with its officers, directors and
  certain key employees implementing such indemnification. </FONT></P>

  undertakes that, for purposes of determining any liability under the Securities
  Act, each filing of the Registrant's annual report pursuant to Section 13(a) or
  Section 15(d) of the Exchange Act that is incorporated by reference in this

  <P align=justify><FONT face="Times New Roman" size=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; C. Insofar as indemnification for
  liabilities arising under the Securities Act may be permitted to directors,
  officers and controlling persons of the Registrant pursuant to the foregoing
  provisions, or otherwise, the Registrant has been advised that in the opinion of
  the Commission such indemnification is against public policy as expressed in the
  Securities Act and is, therefore, unenforceable. In the event that a claim for
  indemnification against such liabilities (other than the payment by the
  Registrant of expenses incurred or paid by a director, officer or controlling
  person of the Registrant in successful defense of any action, suit or
  proceeding) is asserted by such director, officer or controlling person in
  connection with the securities being registered hereunder, the Registrant will,
  unless in the opinion of its counsel the matter has been settled by controlling
  precedent, submit to a court of appropriate jurisdiction the question of whether
  such indemnification by it is against public policy as expressed in the
  Securities Act and will be governed by the final adjudication of such issue.

  ITEM 3.
  Incorporation of Documents by
  Reference
  .
  The following documents filed with
  the Securities and Exchange Commission (the "Commission") are hereby
  incorporated by reference in this Registration Statement of Quantum Corporation
  (referred to herein as the "Registrant"): (a) the Registrant's Annual Report on
  Form 10-K for the fiscal year ended March 31, 2012, filed with the Commission
  pursuant to Section 13 of the Securities Exchange Act of 1934, as amended (the
  "Exchange Act"), on June 14, 2012; (b) all other reports filed by the Registrant
  with the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act since
  the end of the fiscal year covered by the Annual Report referred to in clause
  (a) above (other than the portions of those documents not deemed to be filed);
  and (c) the description of the Registrant's QTM Common Stock contained in the
  Registrant's Registration Statement on Form 8-A filed with the Commission on
  July 21, 1999 pursuant to Section 12(b) of the Exchange Act and any amendment or
  report filed for the purpose of updating such description.
  All documents filed by the
  Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act
  on or after the date of this Registration Statement and prior to the filing of a
  post-effective amendment to this Registration Statement which indicates that all
  securities offered pursuant to this Registration Statement have been sold or
  which deregisters all securities then remaining unsold (other than the portions
  of these documents not deemed to be filed), shall be deemed to be incorporated
  by reference in this Registration Statement and to be part hereof from the date
  of filing of such documents. Any statement contained in a document incorporated
  or deemed to be incorporated by reference in this Registration Statement shall
  be deemed to be modified or superseded for purposes of this Registration
  Statement to the extent that a statement contained herein modifies or supersedes
  such statement. Any such statement so modified or superseded shall not be
  deemed, except as so modified or superseded, to constitute a part of this

  Indemnification of Directors and
  Officers
  .
  Section 145 of the Delaware General
  Corporation Law authorizes a court to award, or a corporation's Board of
  Directors to grant, indemnification to directors and officers in terms
  sufficiently broad to permit such indemnification under certain circumstances
  for liabilities (including reimbursement for expenses incurred) arising under
  the Securities Act of 1933, as amended (the "Securities Act"). The Registrant's
  Amended and Restated Certificate of Incorporation contains a provision
  eliminating the personal liability of the Registrant's directors to the
  Registrant or its stockholders for breach of fiduciary duty as a director to the
  fullest extent permitted by applicable law. The Registrant's Bylaws, as amended,
  provide for the indemnification of its directors, officers, employees and other
  agents to the maximum extent permitted by Delaware General Corporation Law, and
  the Registrant has entered into agreements with its officers, directors and
  certain key employees implementing such indemnification.

  Undertakings
  .
  A.
  The undersigned Registrant hereby undertakes:
  (1) To file, during any period in
  which offers or sales are being made, a post-effective amendment to this
  Registration Statement:
  (i) To include any prospectus
  required by Section 10(a)(3) of the Securities Act;
  (ii) To reflect in the prospectus
  any facts or events arising after the effective date of the Registration
  Statement (or the most recent post-effective amendment thereof) which,
  individually or in the aggregate, represent a fundamental change in the
  information set forth in the Registration Statement. Notwithstanding the
  foregoing, any increase or decrease in volume of securities offered (if the
  total dollar value of securities offered would not exceed that which was
  registered) and any deviation from the low or high end of the estimated maximum
  offering range may be reflected in the form of prospectus filed with the
  Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume
  and price represent no more than a 20 percent change in the maximum aggregate
  offering price set forth in the "Calculation of Registration Fee" table in the
  effective Registration Statement;
  2
  (iii) To include any material
  information with respect to the plan of distribution not previously disclosed in
  the Registration Statement or any material change to such information in the
  Registration Statement;
  provided, however,
  that paragraphs (a)(1)(i) and
  (a)(1)(ii) do not apply if the information required to be included in a
  post-effective amendment by those paragraphs is contained in reports filed with
  or furnished to the Commission by the Registrant pursuant to Section 13 or
  Section 15(d) of the Exchange Act that are incorporated by reference in the
  Registration Statement.
  (2) That, for the purpose of
  determining any liability under the Securities Act, each such post-effective
  amendment shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that time
  shall be deemed to be the initial bona fide
  offering thereof.
  (3) To remove from registration by
  means of a post-effective amendment any of the securities being registered which
  remain unsold at the termination of the offering.
  B. The undersigned Registrant hereby
  undertakes that, for purposes of determining any liability under the Securities
  Act, each filing of the Registrant's annual report pursuant to Section 13(a) or
  Section 15(d) of the Exchange Act that is incorporated by reference in this
  Registration Statement shall be deemed to be a new registration statement
  relating to the securities offered therein, and the offering of such securities
  at that time shall be deemed to be the initial bona fide offering thereof.
  C. Insofar as indemnification for
  liabilities arising under the Securities Act may be permitted to directors,
  officers and controlling persons of the Registrant pursuant to the foregoing
  provisions, or otherwise, the Registrant has been advised that in the opinion of
  the Commission such indemnification is against public policy as expressed in the
  Securities Act and is, therefore, unenforceable. In the event that a claim for
  indemnification against such liabilities (other than the payment by the
  Registrant of expenses incurred or paid by a director, officer or controlling
  person of the Registrant in successful defense of any action, suit or
  proceeding) is asserted by such director, officer or controlling person in
  connection with the securities being registered hereunder, the Registrant will,
  unless in the opinion of its counsel the matter has been settled by controlling
  precedent, submit to a court of appropriate jurisdiction the question of whether
  such indemnification by it is against public policy as expressed in the
  Securities Act and will be governed by the final adjudication of such issue.
