                                     PART II

                 INFORMATION REQUIRED IN REGISTRATION STATEMENT


Item 3.  Incorporation of Documents by Reference

         There  are  hereby  incorporated  by  reference  in  this  Registration
Statement the  following  documents and  information  heretofore  filed with the
Securities and Exchange Commission (Quantum Corporation is sometimes referred to
herein as the "Company"):

                  (a) The  Company's  Annual  Report on Form 10-K for the fiscal
         year  ended  March  31,  1997,  filed  pursuant  to  Section  13 of the
         Securities Exchange Act of 1934, as amended (the "1934 Act");

                  (b) The  Company's  current  report on Form 8-K filed  June 2,
         1997 pursuant to Section 13 of the 1934 Act.

                  (c) The description of the Company's Common Stock contained in
         the Company's  Registration  Statement on Form 8-A filed August 1, 1983
         pursuant to Section 12(b) of the 1934 Act.

         All documents filed by the Company  pursuant to Sections 13(a),  13(c),
14 and 15(d) of the 1934 Act on or after the date of this Registration Statement
and prior to the filing of a  post-effective  amendment which indicates that all

Item 6.  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  Company's  Bylaws
         provide for the mandatory  indemnification of its directors,  officers,
         employees and other agents to the maximum extent  permitted by Delaware
         General  Corporation  Law, and the Company has entered into  agreements
         with its officers,  directors  and certain key  employees  implementing

Item 9.  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 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.

            (2) That,  for the purpose of  determining  any liability  under the
Securities Act of 1933, 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


                                      II-2




initial bonafide 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 of 1933,  each
filing of the  registrant's  annual report  pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing
of an employee  benefit  plan's annual  report  pursuant to Section 15(d) of the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
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 bonafide offering thereof.

                  C. Insofar as  indemnification  for liabilities  arising under
the Securities Act of 1933 (the "Securities Act") may be permitted to directors,
officers and controlling persons of the Company pursuant to the Delaware General
Corporation Law, the Certificate of Incorporation of the Company,  the Bylaws of
the Company, indemnification agreements entered into between the Company and its
officers and  directors or  otherwise,  the Company has been advised that in the
opinion of the  Securities  and  Exchange  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 Company 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 Company
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.
