                           INDEMNIFICATION AGREEMENT
                           -------------------------

This Indemnification Agreement ("Agreement") is made as of this _____ day of
January, 2001, by and between Quantum Corporation, a Delaware corporation (the
"Company") and __________ (Indemnitee"), a Vice President of the Company.

          WHEREAS, the Company and Indemnitee recognize the increasing
difficulty in obtaining directors' and officers' liability insurance, the
significant increases in the cost of such insurance and the general reductions
in the coverage of such insurance; and

          WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation subjecting officers and directors to expensive
litigation risks at the same time that liability insurance has been severely
limited; and

          WHEREAS, Indemnitee does not regard the current protection available
as adequate given the present circumstances, and Indemnitee and other officers
and directors of the Company may not be willing to serve as officers and
directors without adequate protections; and

          WHEREAS, the Company desires to attract and retain the services of
highly qualified individuals, such as Indemnitee, to serve as officers and
directors of the Company and to indemnify its officers and directors as to
provide them with the maximum protection permitted by law.

          NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

1.        Indemnification.
          ---------------

          (a) Third Party Proceedings. The Company shall indemnify Indemnitee if
              -----------------------
Indemnitee is or was a party or is threatened to be made a party to any
threatened, pending or completed action, suite or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Company) by reason of the fact that Indemnitee is or was a
director, officer, employee or agent of the Company or any subsidiary of the
Company, by reason of any action or inaction on the part of Indemnitee while an
officer or director or by reason of the fact that Indemnitee is or was serving
at the request of the Company as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorney's fees), judgments, fines and amounts paid
in settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) actually and reasonably incurred by
Indemnitee in connection with such action, suit or proceeding if Indemnitee
acted in good faith and in a manner Indemnitee reasonably believed to be in or
not opposed to the best interests of the Company, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe Indemnitee's
conduct was unlawful. The termination of any action, suite or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
                                                           ---- ----------
its equivalent, shall not, of itself, create a presumption that Indemnitee did
not act in good faith and in a manner which Indemnitee reasonably believed to be
in or not opposed to the best interests of the Company, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that Indemnitee's
conduct was unlawful.
<PAGE>

          (b) Proceedings by or in the Right of the Company. The Company shall
              ---------------------------------------------
indemnify Indemnitee if Indemnitee was or is a party or is threatened to be made
a party to any threatened, pending or completed action or suit by or in the
right for the Company or any subsidiary of the Company to procure a judgment in
its favor by reason of the fact that Indemnitee is or was a director, officer,
employee or agent of the Company or any subsidiary of the Company by reason of
any action or inaction on the part of Indemnitee while an officer or director or
by reason of the fact that Indemnitee is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorney's fees) and, to the fullest extent permitted by law, amounts
paid in settlement in each case to the extent actually and reasonably incurred
by Indemnitee in connection with the defense or settlement of such action or
suit if Indemnitee acted in good faith and in a manner Indemnitee reasonably
believed to be in or not opposed to the best interests of the Company and except
that no indemnification shall be made in respect of any claim, issue or matter
as to which Indemnitee shall have been adjudged to be liable to the Company
unless and only to the extent that the Court of Chancery of the State of
Delaware or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of all
the circumstances of the case, Indemnitee is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery of the State of Delaware
or such other court shall deem proper.

          (c) Mandatory Payment of Expenses. To the extent that Indemnitee has
              -----------------------------
been successful on the merit or otherwise in defense of any action, suit or
proceeding referred to in Subsections (a) and (b) of the Section 1 or the
defense of any claim, issue or matter therein, Indemnitee shall be indemnified
against expenses (including attorney's fees) actually and reasonably incurred by
Indemnitee in connection therewith.

2.        Expenses: Indemnification Procedure.
          -----------------------------------

          (a) Advancement of Expenses. The Company shall advance all expenses
              -----------------------
incurred by Indemnitee in connection with the investigation, defense, settlement
or appeal of any civil or criminal action, suit or proceeding referenced in
Section l(a) or (b) hereof. Indemnitee hereby undertakes to repay such amounts
advanced only if, and to the extent that, it shall ultimately be determined that
Indemnitee is not entitled to be indemnified by the Company as authorized
hereby. The advances to be made hereunder shall be paid by the Company to
Indemnitee within twenty (20) days following delivery of a written request
therefor, together with evidence of such expenses incurred, by Indemnitee to the
Company.

          (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a condition
              --------------------------------
precedent to his right to be indemnified under this Agreement, give the Company
notice in writing as soon as practicable of any claim made against Indemnitee
for which indemnification will or could be sought under this Agreement. Notice
to the Company shall be directed to Quantum Corporation, 500 McCarthy Boulevard,
Milpitas, California 95035 (Attn: Michael A. Brown) (or such address as the
Company shall designate in writing to Indemnitee).  Notice shall be deemed
received on the third business day after the date postmarked if sent by domestic
certified or registered mail, properly addressed; otherwise notice shall be
deemed received when such notice shall actually be received by the Company.  In
addition, Indemnitee shall give the Company such information and cooperation as
it may reasonably require and as shall be within Indemnitee's power.

          (c) Procedure.  Any indemnification and advances provided for in
              ---------
Section (a) of this Section 2 shall be made no later than forty-five (45) days
after receipt of the written request of Indemnitee.  If a claim under this
Agreement, under any statute, or under any provision of the Company's
Certificate of Incorporation or Bylaws providing for indemnification, is not
paid in full by the Company within forty- five (45) days after a written request
for payment thereof has first been received by the Company, Indemnitee may, but
need not, at any time thereafter bring an action against the Company to recover
the unpaid amount of the claim and, subject to Section 12 of this Agreement,
Indemnitee shall also be entitled to be paid for the expenses (including
attorney's fees) of bringing such action.  It shall be a defense to any such
action (other than an action brought to enforce a claim for expenses incurred in
connection with any action, suit or
<PAGE>

proceeding in advance of its final disposition) that Indemnitee has not met the
standard of conduct which makes it permissible under applicable law for the
Company to indemnify Indemnitee for the amount claimed, but the burden of
proving such defense shall be on the Company and Indemnitee shall be entitled to
receive interim payments and expenses pursuant to Subsection 2(a) unless and
until such defense may be finally adjudicated by court order or judgment from
which no further right of appeal either exists or is pursued within six months
from the date of such court order of judgment. It is the parties' intention that
if the Company contests Indemnitee's right to indemnification, the question of
Indemnitee's right to indemnification shall be for the court to decide, and
neither the failure of the Company (including its Board of Directors, any
committee or subgroup of the Board of Directors, independent legal counsel, or
its stockholder) to have made a determination that indemnification of Indemnitee
is proper in the circumstances because Indemnitee has met the applicable
standard of conduct required by applicable law, nor an actual determination by
the Company (including its Board of Directors, any committee or subgroup of the
Board of Directors, independent legal counsel, or its stockholders) that
Indemnitee has not met such applicable standard of conduct, shall create a
presumption that Indemnitee has or has not met the applicable standard of
conduct.

          (d) Notice to Insurers.  If, at the time of the receipt of a notice of
              ------------------
a claim pursuant to Section 2(b) hereof, the Company has director and officer
liability insurance in effect, the Company shall give prompt notice of the
commencement of such proceeding to the insurers in accordance with the procedure
set forth in the respective policies. The Company shall thereafter take all
necessary or desirable action to cause such insurers to pay, on behalf of the
Indemnitee, all amounts payable as a result of such proceeding in accordance
with the terms of such policies.

          (e) Selection of Counsel.  In the event the Company shall be obligated
              --------------------
under Section 2(a) hereof to pay the expenses of any proceeding against
Indemnitee, the Company shall be entitled to assume the defense of such
proceeding, with counsel approved by Indemnitee, upon the delivery to Indemnitee
of written notice of its election to do so.  After delivery of such notice,
approval of such counsel by Indemnitee and the retention of such counsel by the
Company, the Company will not be liable to Indemnitee under this Agreement for
any fees of counsel subsequently incurred by Indemnitee with respect to the same
proceeding, provided that (i) Indemnitee shall have the right to employ his
counsel in any such proceedings at Indemnitee's expense and (ii) if (A) the
employment of counsel by Indemnitee has been previously authorized by the
Company, (B) Indemnitee and its counsel shall have reasonably concluded that
there may be a conflict of interest between the Company and Indemnitee in the
conduct of any such defense or (C) the Company shall not, in fact, have employed
counsel to assume the defense of such proceeding, then the fees and expenses of
Indemnitee's counsel shall be at the expense of the Company.

3.        Additional Indemnification Rights: Non-Exclusivity.
          --------------------------------------------------

          (a) Scope.  Notwithstanding any other provision of the Agreement, the
              -----
Company hereby agrees to indemnify Indemnitee to the fullest extent permitted by
law, notwithstanding that such indemnification is not specifically authorized by
the other provisions of this Agreement, the Company's:Certificate of
Incorporation, the Company's bylaws or by statute.  In the event of any changes,
after the date of the Agreement, in any applicable law, statute, or rule which
expands the right of a Delaware corporation to indemnify a member of its board
of directors or any officer, such changes shall be, ipso facto, within the
                                                    ---- -----
purview of the Indemnitee's rights and the Company obligations under this
Agreement.  In the event of any change in any applicable law, statute, or rule
which narrows the right of a Delaware corporation to indemnify a member of its
board of directors or any officer, such changes, to the extent not otherwise
required by such law, statute or rule to be applied to the Agreement shall have
no effect on this Agreement or the parties' rights and obligations hereunder.

          (b) Nonexclusivity.  The indemnification provided by this Agreement
              --------------
shall not be deemed exclusive of any rights to which an Indemnitee may be
entitled under the Company's Certificate of Incorporation, its Bylaws, any
agreement, any vote of stockholders or disinterested Directors, the General
Corporation Law of the State of Delaware, or otherwise, both as to action in
Indemnitee's official capacity and as to action in another capacity while
holding such office.
<PAGE>

The indemnification provided under this Agreement shall continue as to
Indemnitee for any action taken or not taken while serving in an indemnified
capacity even though he may have ceased to serve in such capacity at the time of
any action, suit or other covered proceeding.

4.  Partial Indemnification.  If Indemnitee is entitled under any provision of
    -----------------------
this Agreement to indemnification by the Company for some or a portion of the
expenses, judgments, fines or penalties actually or reasonably incurred by him
in the investigation, defense, appeal or settlement of any civil or criminal
action, suit or proceeding, but not, however, for the total amount thereof, the
Company shall nevertheless indemnify Indemnitee for the portion of such
expenses, judgments, fines or penalties to which Indemnitee is entitled.

5.  Mutual Acknowledgment.  Both the Company and Indemnitee acknowledge that in
    ---------------------
certain instances, Federal law or applicable public policy may prohibit the
Company from indeminfying its directors and officers under this Agreement or
otherwise.  For example, the Company and Indemnitee acknowledge that the
Securities and Exchange Commission (the "SEC") has taken the position that
indemnification is not permissible for liabilities arising under certain federal
securities laws, and federal legislation prohibits indemnification for certain
ERISA violation.  Indemnitee understands and acknowledges that the Company has
undertaken or may be required in the future to undertake with the SEC to submit
the question of indemnification to a court in certain circumstances for a
determination of the Company's right under public policy to indemnify
Indemnitee.

6.  Directors' and Officers' Liability Insurance.  The Company shall, from time
    --------------------------------------------
to time, make the good faith determination whether or not it is practicable for
the Company to obtain and maintain a policy or policies of insurance with
reputable insurance companies providing the directors and officers with coverage
for losses from wrongful acts, or to ensure the Company's performance of its
indemnification obligations under this Agreement.  Among other considerations,
the Company will weigh the costs of obtaining such insurance coverage against
the protection afforded by such coverage.  In all policies of directors' and
officers' liability insurance, Indemnitee shall be named as an insured in such a
manner as to provide Indemnitee the same rights and benefits as are accorded to
the most favorably insured of the Company's directors, if Indemnitee is a
director; or of the Company's officers, if Indemnitee is not a director of the
Company but is an officer.  Notwithstanding the foregoing, the Company shall
have no obligation to obtain or maintain such insurance if the Company
determines in good faith that such insurance is not reasonably available, if the
premium costs for such insurance are disproportionate to the amount of coverage
provided, if the coverage provided by such insurance is limited by exclusions so
as to provide an insufficient benefit, or if Indemnitee is covered by similar
insurance maintained by a parent or subsidiary of the Company.

7.  Severability.  Nothing in this Agreement is intended to require or shall be
    ------------
construed as requiring the Company to do or fail to do any act in violation of
applicable law.  The Company's inability, pursuant to court order, to perform
its obligations under this Agreement shall not constitute a breach of this
Agreement.  The provisions of this Agreement shall be severable as provided in
this Section 7.  If this Agreement or any portion hereof shall be invalidated on
any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify Indemnitee to the full extent permitted by any applicable
portion of this Agreement that shall not have been invalidated, and the balance
of this Agreement not so invalidated shall be enforceable in accordance with its
terms.

8.  Exceptions.  Any other provision herein to the contrary notwithstanding, the
    ----------
Company shall not be obligated pursuant to the terms of this Agreement:

    (a) Claims Initiated by Indemnitee. To indemnify or advance expenses
        ------------------------------
to Indemnitee with respect to proceedings or claims initiated or brought
voluntarily by Indemnitee and not by way of defense, except with respect to
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other statute or law or otherwise as required under
Section 145 of the Delaware General Corporation Law, but such indemnification or
advancement of expenses may be provided by the Company in specific cases if the
Board of Directors has approved the initiation of such suit:
<PAGE>

          (b) Lack of Good Faith. To indemnify Indemnitee for any expenses
              ------------------
incurred by the Indemnitee with respect to any proceeding instituted by
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
Indemnitee in such proceeding was not made in good faith or was frivolous;

          (c) Insured Claims. To indemnify Indemnitee for expenses of
              --------------
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA excise taxes or penalties, and amounts paid in settlement) which
have been paid directly to Indemnitee by an insurance carrier under a policy of
officers' and directors' liability insurance maintained by the Company.

          (d) Claims Under Section 16(b). To indemnify Indemnitee for expenses
              --------------------------
or the payment of profits arising from the purchase and sale by Indemnitee of
securities in violation of Section 16(b) of the Securities Exchange Act of 1934,
as amended, or any similar successor statute.

9.        Construction of Certain Phrases.
          -------------------------------

          (a) For purposes of this Agreement, references to the "Company" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger so that if Indemnitee is or was a director, officer, employee or agent of
such constituent corporation, or is or was serving at the request of such
constituent corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, Indemnitee
shall stand in the same position under the provisions of this Agreement with
respect to the resulting or surviving corporation as Indemnitee would have with
respect to such constituent corporation if its separate existence had continued.

          (b) For purposes of this Agreement, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on Indemnitee with respect to an employee benefit plan;
and references to "serving at the request of the Company" shall include any
service as a director, officer, employee or agent of the Company which imposes
duties on, or involved services by, such director, officer, employee or agent
with respect to an employee benefit plan, its participants, or beneficiaries;
and that Indemnitee acted in good faith and in a manner Indemnitee reasonably
believed to be in the interest of the participants and beneficiaries of an
employee benefit plan, Indemnitee shall be deemed to have acted in a manner "not
opposed to the best interests of the Company" as referred to in this Agreement.

10.       Counterparts and Amendment. This Agreement may be executed in
          --------------------------
counterparts, each of which shall constitute an original. This Agreement may
only be amended in writing signed by both parties.

11.       Successors and Assigns. This Agreement shall be binding upon the
          ----------------------
Company and its successors and assigns, and shall inure to the benefit of
Indemnitee and Indemnitee's estate, heirs, legal representatives and assigns.

12.       Attorney's Fees. In the event that any action is instituted by
          ---------------
Indemnitee under this Agreement to enforce or interpret any of the terms hereof,
Indemnitee shall be entitled to be paid all court costs and expenses, including
reasonable attorneys' fees, incurred by Indemnitee with respect to such action,
unless as a part of such action, the court of competent jurisdiction determines
that each of the material assertions made by Indemnitee as a basis for such
action were not made in good faith or were frivolous. In the event of an action
instituted by or in the name of the Company under this Agreement or to enforce
or interpret any of the terms of this Agreement, Indemnitee, shall be entitled
to be paid all court costs and expenses, including attorneys' fees, incurred by
Indemnitee in defense of such action (including with respect to Indemnitee's
counterclaims and cross-claims made in such action), unless as a part of such
action the court determines that each of Indemnitee's material defenses to such
action were made in bad faith or were frivolous.

     ------

                                                                    Exhibit 10.2

                          CHANGE OF CONTROL AGREEMENT

     THIS CHANGE OF CONTROL AGREEMENT ("Agreement") is effective as of this
1/st/ day of April, 2001, by and between _________________ (the "Employee") and
QUANTUM CORPORATION, a Delaware corporation (the "Corporation").

                                   Recitals
                                   --------

     A.   The board of directors of the Corporation has determined that it is in
the best interests of the Corporation and its stockholders to assure that the
Corporation will have the continued dedication and objectivity of the Employee,
notwithstanding the possibility, threat or occurrence of a Change of Control (as
defined below) of the Corporation.

     B.   The board of directors believes that it is important to provide the
Employee with compensation arrangements and stock benefits upon a Change of
Control which provide the Employee with enhanced financial security, are
competitive with those of other corporations, and provide sufficient incentive
to the Employee to remain with the Corporation following a Change of Control.

     C.   In order to accomplish the foregoing objectives, the board of
directors has directed the Corporation, upon execution of this Agreement by the
Employee, to agree to amend and restate the terms of this Agreement as in effect
since its original effective date and to extend the terms of this Agreement as
set forth below.

     D.   Certain capitalized terms used in the Agreement are defined in Section
3 below.

     In consideration of the mutual covenants herein contained, and in
consideration of the continuing employment of Employee by the Corporation, the
parties agree as follows:

     1.   Change of Control Severance Benefits.  Subject to Section 4 below, if
          ------------------------------------
the employee's employment terminates at any time within eighteen (18) months
after a Change of Control, then the following shall apply:

          (a)  Voluntary Resignation; Termination For Cause.  If the Employee's
               --------------------------------------------
employment terminates in a voluntary resignation (and not an Involuntary
Termination), or if the Employee is terminated for Cause, or if Employee
voluntarily accepts a position below the level of vice president then the
Employee shall not be entitled to receive severance or other benefits except for
those (if any) as may be available under the Corporation's severance and
benefits plans and policies existing at the time of such termination.
<PAGE>

          (b)  Involuntary Termination.  If the Employee suffers an Involuntary
               -----------------------
Termination, then the Employee shall be entitled to:

               (i)    Receive severance pay in an amount equal to twelve (12)
months of the Employee's then established Base Compensation plus

               (ii)   Receive reimbursements from the Corporation for the same
level of health coverage and benefits as in effect for the Employee on the day
immediately preceding the day of the Employee's termination of employment;
provided, however, that (i) the Employee constitutes a qualified beneficiary, as
defined in Section 4980B(g)(1) of the Internal Revenue Code of 1986, as amended;
and (ii) Employee elects continuation coverage pursuant to the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), within the time
period prescribed pursuant to COBRA. The Corporation shall continue to reimburse
Employee for continuation coverage until one year after the date of the
Involuntary Termination. Employee shall be responsible for the payment of COBRA
premiums (including, without limitation, all administrative expenses) for the
remaining COBRA period.

          (c)  Disability; Death.  If the Employee's employment terminates due
               -----------------
to the Employee's Disability or death, then such termination shall be treated as
if it were an Involuntary Termination and severance and other benefits shall be
provided in accordance with paragraph (b) above.

     2.   Option and Stock Acceleration.
          -----------------------------

          (a)  Acceleration Upon Change of Control.  Subject to Section 4 below,
               -----------------------------------
in the event of a Change of Control:

               (i)    Fifty percent (50%) of the then unvested portion of any
stock option held by the Employee under the Corporation's stock option plans and
outstanding at the time of the Change of Control shall become vested and the
Employee shall automatically have the right to exercise all or any portion of
such stock option to the extent so vested in addition to any portion of the
option exercisable prior to the Change of Control;

               (ii)   Fifty percent (50%) of any unvested shares held by the
Employee under any common stock purchase agreement with the Corporation and
outstanding at the time of the Change of Control shall automatically become
vested shares, and such shares shall automatically be free of any right of
repurchase to the extent so vested in addition to any shares which were vested
prior to the Change of Control.

Where the Change of Control results from a merger or consolidation of the
Corporation with any other corporation, such vesting shall occur prior to
consummation of such merger or consolidation, no less than ten (10) days prior
to such merger or consolidation.

          (b)  Option Acceleration Following Change of Control.  Subject to the
               -----------------------------------------------
continued employment of the Employee, after acceleration of vesting under
paragraph (a)(i) the remaining

                                      -2-
<PAGE>

unvested portion of any stock option shall become fully vested upon the first
anniversary of the Change of Control (or the expiration date of such stock
option, if earlier). If, however, the Employee's employment terminates within
the twelve (12) month period following a Change of Control, then, subject to
Section 4 below, the exercisability of any stock option held by the Employee
shall be as follows:

               (i)    Voluntary Resignation; Termination for Cause.  If the
                      --------------------------------------------
Employee's employment terminates in a voluntary resignation (and not an
Involuntary Termination), or if the Employee is terminated for Cause, the
Employee is entitled to exercise any vested stock option (including an option
vested under paragraph (a)(i) above).

               (ii)   Involuntary Termination.  If the Employee suffers an
                      -----------------------
Involuntary Termination, then the portion of any stock option then held by the
Employee that is not vested and exercisable shall automatically become vested
and exercisable.

               (iii)  Disability; Death.  If the Employee's employment
                      -----------------
terminates due to the Employee's Disability or death, then such termination
shall be treated as if it were an Involuntary Termination for purposes of this
Section 6.

          (c)  Acceleration of Unvested Shares Following Change of Control.
               -----------------------------------------------------------
Subject to the continued employment of the Employee, any unvested shares
following the acceleration provided in paragraph (a)(ii) above shall vest on the
date of the first anniversary following the Change of Control.  If, however, the
Employee's employment is terminated within the twelve (12) month period
following a Change of Control, then, subject to Section 4 of the Agreement, any
shares held by the Employee under any common stock purchase agreement with the
Corporation shall become vested shares as follows:

               (i)    Voluntary Resignation; Termination for Cause.  If the
                      --------------------------------------------
Employee's employment terminates in a voluntary resignation (and not an
Involuntary Termination), or if the Employee is terminated for Cause, then the
Employee shall receive only his or her vested shares (including the shares
vested under paragraph (a)(ii) above).

               (ii)   Involuntary Termination.  If the Employee suffers an
                      -----------------------
Involuntary Termination, then all of the Employee's shares shall vest.

               (iii)  Disability; Death.  If the Employee's employment
                      -----------------
terminates due to the Employee's Disability or death, then such termination
shall be treated as if it were an Involuntary Termination for purposes of this
Section 2.

     3.   Definition of Terms.  The following terms referred to in this
          -------------------
Agreement shall have the following meanings:

          (a)  Base Compensation.  "Base Compensation" shall mean the base

                                      -3-
<PAGE>

          (b)  Change of Control.  "Change of Control shall mean the occurrence
               -----------------
of any of the following events:

               (i)    Any "person" (as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended) is or becomes the
"beneficial owner" (as defined in Rule l3d-3 under said Act), directly or
indirectly, of securities of the Corporation representing forty percent (40%) or
more of the total voting power represented by the Corporation's then outstanding
voting securities; or

               (ii)   A change in the composition of the board of directors of
the Corporation occurring within a six (6) month period, as a result of which
fewer than a majority of the directors are Incumbent Directors. "Incumbent
Directors" shall mean directors who either (A) are directors of the Corporation
as of the date hereof, or (B) are elected, or nominated for election, to the
board of directors of the Corporation with the affirmative votes of at least a
majority of the Incumbent Directors at the time of such election or nomination
(but shall not include an individual whose election or nomination is in
connection with an actual or threatened proxy contest relating to the election
of directors to the Corporation); or

               (iii)  The stockholders of the Corporation approve a merger or
consolidation of the Corporation with any other corporation, other than a merger
or consolidation which would result in the voting securities of the Corporation
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) at least fifty percent (50%) of the total voting power
represented by the voting securities of the Corporation or such surviving entity
outstanding immediately after such merger or consolidation, or the stockholders
of the Corporation approve a plan of complete liquidation of the Corporation or
an agreement for the sale or disposition by the Corporation of all or
substantially all the Corporation's assets.

          (c)  Involuntary Termination.  "Involuntary Termination" shall mean
               -----------------------
(i) without the Employee's express written consent, the assignment to the
Employee of any duties or the reduction of the Employee's duties, either of
which results in a significant diminution in the Employee's position or
responsibilities with the Corporation in effect immediately prior to such
assignment, or the removal of the Employee from such position and
responsibilities; (ii) without the Employee's express written consent, a
substantial reduction of the facilities and perquisites (including office space
and location) available to the Employee immediately prior to such reduction;
(iii) a reduction by the Corporation in the Base Compensation of the Employee as
in effect immediately prior to such reduction; (iv) a material reduction by the
Corporation in the kind or level of employee benefits to which the Employee is
entitled immediately prior to such reduction with the result that the Employee's
overall benefits package is significantly reduced; (v) the relocation of the
Employee to a facility or a location more than 25 miles from the Employee's then
present location, without the Employee's express written consent; (vi) any
purported termination of the Employee by the Corporation which is not effected

                                      -4-
<PAGE>

          (d)  Cause.  "Cause" shall mean (i) any act of personal dishonesty
               -----
taken by the Employee in connection with his responsibilities as an employee
that is intended to result in substantial personal enrichment of the Employee,
(ii) the conviction of a felony, (iii) a willful act by the Employee which
constitutes gross misconduct injurious to the Corporation, and (iv) continued
violations by the Employee of the Employee's obligations under Section 1 of this
Agreement which are demonstrably willful and deliberate on the Employee's part
after the Corporation has delivered a written demand for performance to the
Employee that describes the basis for the Corporation's belief that the Employee
has not substantially performed his duties.

          (e)  Disability.  "Disability" shall mean that the Employee has been
               ----------
unable to perform his duties under this Agreement as the result of his
incapacity due to physical or mental illness with or without reasonable
accommodation, and such inability, at least 26 weeks after its commencement, is
determined to be total and permanent by a physician selected by the Corporation
or its insurers and acceptable to the Employee or the Employee's legal
representative (such statement as to acceptability not to be unreasonably
withheld).  Termination resulting from Disability may only be effected after at
least thirty (30) days' written notice by the Corporation of its intention to
terminate the Employee's employment.  In the event that the Employee resumes the
performance of substantially all of his duties hereunder before the termination
of his employment becomes effective, the notice of intent to terminate shall
automatically be deemed to have been revoked.

          (f)  Disinterested Board.  "Disinterested Board" shall mean the board
               -------------------
of directors of the Corporation excluding those members of the board of
directors, if any, who are parties to agreements or arrangements identical to or
substantially similar to this Agreement.

     4.   Limitation on Payments.
          ----------------------

          (a)  Basic Rule.  In the event that any payment or benefit received or
               ----------
to be received by the Employee in connection with a termination of his
employment with the Corporation (collectively, the "Severance Payments") would
(i) constitute a "parachute payment" within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended (the "Code"), or any similar or
successor provision to 280G and (ii) but for this Section 8(a), be subject to
the excise tax imposed by Section 4999 of the Code or any similar or successor
provision to Section 4999 (the "Excise Tax"), then, subject to the provisions of
Section 8(b) hereof, such Severance Payments (which Severance Payments shall
collectively be referred to herein as the "Severance Parachute Payments") shall
be reduced to the largest amount which the Employee, in his sole discretion,
determines would result in no portion of the Severance Parachute Payments being
subject to the Excise Tax.  The determination of any required reduction pursuant
to this Section 8(a) (including the determination as to which specific Severance
Parachute Payments shall be reduced) shall be made by the Employee in his sole
discretion, and such determination shall be conclusive and binding upon the
Corporation or any related corporation for all purposes.  The Corporation and
its related corporations waive all claims and rights against the Employee with
respect thereto except as specifically set forth in the next sentence.  If the
Internal Revenue Service (the "IRS") determines that a Severance Parachute
Payment is subject to the Excise Tax, then the Corporation or any related
corporation, as their exclusive remedy, shall seek to enforce the provisions of
Section 8(b) hereof.  Such

                                      -5-
<PAGE>

enforcement of Section 8(b) hereof shall be the only remedy, under any and all
applicable state and federal laws or otherwise, for the Employee's failure to
reduce the Severance Parachute Payments so that no portion thereof is subject to
the Excise Tax. The Corporation or related corporation shall reduce a Severance
Parachute Payment in accordance with Section 8(a) only upon written notice by
the Employee indicating the amount of such reduction, if any.

          (b)  Remedy.  If, notwithstanding the reduction described in Section
               ------
8(a) hereof, the IRS determines that the Employee is liable for the Excise Tax
as a result of the receipt of a Severance Parachute Payment, then the Employee
shall, subject to the provisions of this Agreement, be obligated to pay to the
Corporation (the "Repayment Obligation") an amount of money equal to the
"Repayment Amount".  The Repayment Amount with respect to a Severance Parachute
Payment shall be the smallest such amount, if any, as shall be required to be
paid to the Corporation so that the Employee's net proceeds with respect to any
Severance Parachute Payment (after taking into account the payment of the Excise
Tax imposed on such Severance Parachute Payment) shall be maximized.
Notwithstanding the foregoing, the Repayment amount with respect to a Severance
Parachute Payment shall be zero if a Repayment Amount of more than zero would
not eliminate the Excise Tax imposed on such Severance Parachute Payment.  If
the Excise Tax is not eliminated through the performance of the Repayment
Obligation, the Employee shall pay the Excise Tax.  If the Employee pays the
Excise Tax, the Employee shall be entitled to receive from the Corporation a
cash payment equal to the Primary Excise Tax Amount.  For purposes of this
Section 8(b), the "Primary Excise Tax Amount" shall mean a calculation of the
Employee's Excise Tax liability determined without including any amount paid or
payable to the Employee under the preceding sentence.  The Corporation shall
make such payment to the Employee within thirty (30) days of the Employee's
written request therefor, which request shall include reasonable proof of the
Employee's Excise Tax payment.  The Repayment obligation shall be performed
within thirty (30) days of either (i) the Employee entering into a binding
agreement with the IRS as to the amount of the Employee's Excise Tax liability
or (ii) a final determination by the IRS or a court decision requiring the
Employee to pay the Excise Tax with respect to such a Severance Parachute
Payment from which no appeal is available or is timely taken.

     5.   At-Will Employment.  The Corporation and the Employee acknowledge that
          ------------------
the Employee's employment is at will and may be terminated at any time and for
any reason, with or without notice.  On termination of the Employee's
employment, the Employee shall not be entitled to any payments, benefits,
damages, awards or compensation other than as provided by this Agreement, or as
may otherwise be available in accordance with the Corporation's established
employee plans and policies at the time of termination.

     6.   Term, Amendment and Termination.
          -------------------------------

          (a)  Term.  Subject to subsection (b) below, the terms of this
               ----
Agreement shall terminate upon the earlier of (i) the date that all obligations
of the parties hereunder have been satisfied, (ii) April 1, 2003, or (iii)
eighteen (18) months after a Change of Control.  A termination of the terms of
this Agreement pursuant to the preceding sentence shall be effective for all
purposes, except that such termination shall not affect the payment or provision
of compensation or benefits on

                                      -6-
<PAGE>

account of a termination of employment occurring prior to the termination of the
terms of this Agreement.

          (b)  Amendment and Termination.  This Agreement may be amended in any
               -------------------------
respect or terminated by the unanimous resolution of the Disinterested Board,
unless a Change of Control has previously occurred.  If a Change of Control
occurs, this Agreement shall no longer be subject to amendment, change,
substitution, deletion, revocation or termination in any respect whatsoever.

          (c)  Form of Amendment.  The Form of any proper amendment or
               -----------------
termination of this Agreement shall be a written instrument signed by a duly
authorized officer or officers of the Corporation, certifying that the amendment
or termination has been approved by the Disinterested Board in accordance with
Section 6(b).

     7.   Successors.
          ----------

          (a)  Corporation's Successors.  Any successor to the Corporation
               ------------------------
(whether direct or indirect and whether by purchase, lease, merger,
consolidation, liquidation or otherwise) to all or substantially all of the
Corporation's business and/or assets shall assume the obligations under this
Agreement and agree expressly to perform the obligations under this Agreement in
the same manner and to the same extent as the Corporation would be required to
perform such obligations in the absence of a succession.  For all purposes under
this Agreement, the term "Corporation" shall include any successor to the
Corporation's business and/or assets which executes and delivers the assumption
agreement described in this subsection (a) or which becomes bound by the terms
of this Agreement by operation of law.

          (b)  Employee's Successors.  The terms of this Agreement and all
               ---------------------
rights of the Employee hereunder shall inure to the benefit of, and be
enforceable by, the Employee's personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees.

          (c)  Employment By Subsidiaries.  If the Employee is employed by a
               --------------------------
wholly owned subsidiary of Quantum Corporation, then (i) "Corporation" as
defined herein shall be deemed to include such subsidiary, and (ii) the effects
intended to result from a Change of Control under this Agreement shall apply to
such subsidiary, and the Employee shall be entitled to all the benefits and
subject to all the obligations provided herein.

     8.   Notice.
          ------

          (a)  General.  Notices and all other communications contemplated by
               -------
this Agreement shall be in writing and shall be deemed to have been duly given
when personally delivered or when mailed by U.S. registered or certified mail,
return receipt requested and postage prepaid.  In the case of the Employee,
mailed notices shall be addressed to him at the home address which he most
recently communicated to the Corporation in writing.  In the case of the
Corporation, mailed notices shall be addressed to its corporate headquarters,
and all notices shall be directed to the attention of its Secretary.

                                      -7-
<PAGE>

          (b)  Notice of Termination.  Any termination by the Corporation for
               ---------------------
Cause or by the Employee as a result of an Involuntary Termination shall be
communicated by a notice of termination of the other party hereto given in
accordance with Section 11 of this Agreement.  Such notice shall indicate the
specific termination provision in this Agreement relied upon, shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination under the provision so indicated, and shall specify the termination
date (which shall be not more than fifteen (15) days after the giving of such
notice).  The failure by the Employee to include in the notice any fact or
circumstance which contributes to a showing of Involuntary Termination shall not
waive any right of the Employee hereunder or preclude the Employee from
asserting such fact or circumstance in enforcing his rights hereunder.

     9.   Miscellaneous Provisions.
          ------------------------

          (a)  No Duty to Mitigate.  The Employee shall not be required to
               -------------------
mitigate the amount of any payment contemplated by this Agreement (whether by
seeking new employment or in any other manner), nor shall any such payment be
reduced by any earnings that the Employee may receive from any other source.

          (b)  Waiver.  No provision of this Agreement shall be modified, waived
               ------
or discharged unless the modification, waiver or discharge is agreed to in
writing and signed by the Employee and by an authorized officer of the
Corporation (other than the Employee).  No waiver by either party of any breach
of, or of compliance with, any condition or provision of this Agreement by the
other party shall be considered a waiver of any other condition or provision or
of the same condition or provision at another time.

          (c)  Whole Agreement.  No agreements, representations or
               ---------------
understandings (whether oral or written and whether express or implied) which
are not expressly set forth in this Agreement have been made or entered into by
either party with respect to the subject matter hereof.

          (d)  Choice of Law.  The validity, interpretation, construction and
               -------------
performance of this Agreement shall be governed by the laws of the State of
California.

          (e)  Severability.  The invalidity or unenforceability of any
               ------------
provision or provisions of this Agreement shall not affect the validity or
enforceability of any other provision hereof, which shall remain in full force
and effect.

          (f)  Arbitration.
               -----------

               (i)    Employee and the Corporation agree that any dispute or
controversy arising out of, relating to, or in connection with this Agreement,
or the interpretation, validity, construction, performance, breach, or
termination thereof, shall be finally settled by binding arbitration to be held
in Milpitas, California under the National Rules for the Resolution of
Employment Disputes supplemented by the Supplemental Procedures for Large
Complex Disputes, of the American Arbitration Association as then in effect (the
"Rules"). The parties shall be entitled to conduct discovery pursuant to the
California Code of Civil Procedure. The arbitrator may regulate

                                      -8-
<PAGE>

the timing and sequence of such discovery and shall decide any discovery
disputes or controversies between the Corporation. The arbitrator may grant
injunctions or other relief in such dispute or controversy. The decision of the
arbitrator shall be final, conclusive and binding on the parties to the
arbitration. Judgment may be entered on the arbitrator's decision in any court
having jurisdiction.

               (ii)   The arbitrator(s) shall apply California law to the merits
of any dispute or claim, without reference to rules or conflicts of law.

               (iii)  Unless otherwise provided for by law, the Corporation and
the Employee shall each pay half of the costs and expenses of such arbitration.

               (iv)   EMPLOYEE HAS READ AND UNDERSTANDS THIS SECTION, WHICH
DISCUSSES ARBITRATION. EMPLOYEE UNDERSTANDS THAT BY SIGNING THIS AGREEMENT,
EMPLOYEE AGREES TO SUBMIT ANY CLAIMS ARISING OUT OF, OR RELATING TO, OR IN
CONNECTION WITH THIS AGREEMENT, OR THE INTERPRETATION, VALIDITY, CONSTRUCTION,
PERFORMANCE, BREACH OR TERMINATION THEREOF TO BINDING ARBITRATION, AND THAT THIS
ARBITRATION CLAUSE CONSTITUTES A WAIVER OF EMPLOYEE'S RIGHT TO A JURY TRIAL AND
RELATES TO THE RESOLUTION OF ALL DISPUTES RELATING TO ALL ASPECTS OF THIS
AGREEMENT.

          (g)  No Assignment of Benefits.  The rights of any person to payments
               -------------------------
or benefits under this Agreement shall not be made subject to option or
assignment, either by voluntary or involuntary assignment or by operation of

will be subject to withholding of applicable taxes.

          (i)  Assignment by Corporation.  The Corporation may assign its rights
               -------------------------

under this Agreement to another affiliate of the Corporation or to the
Corporation provided, however, that no assignment shall be made if the net worth
of the assignee is less than the net worth of the Corporation at the time of
assignment.  In the case of any such assignment, the term "Corporation" when
used in a section of this Agreement shall mean the Corporation that actually
employs the Employee.

          (j)  Amendment of Option and Purchase Agreements.  The Corporation and
               -------------------------------------------
the Employee agree that the provisions of this Agreement shall supersede any
conflicting provisions of any stock purchase or stock option agreement of the
Employee, and the Corporation and the Employee agree to execute such further
documents as may be necessary to amend any such agreement.

          (l)  Counterparts.  This Agreement may be executed in counterparts,
