                            SEAGATE TECHNOLOGY, INC.

                         MANAGEMENT RETENTION AGREEMENT

     This Management Retention Agreement (the "AGREEMENT") is made and entered
into by and between Stephen J. Luczo (the "EMPLOYEE") and Seagate Technology,
Inc. (the "COMPANY"), effective as of November 12, 1998 (the "EFFECTIVE DATE").

                                 R E C I T A L S
                                 ---------------

          A. It is expected that the Company from time to time will consider the
possibility of an acquisition by another company or other change of control. The
Board of Directors of the Company (the "BOARD") recognizes that such
consideration can be a distraction to the Employee and can cause the Employee to
consider alternative employment opportunities. The Board has determined that it
is in the best interests of the Company and its stockholders to assure that the
Company 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 Company.

          B. The Board believes that it is in the best interests of the Company
and its stock-holders to provide the Employee with an incentive to continue his
employment and to motivate the Employee to maximize the value of the Company
upon a Change of Control for the benefit of its stockholders.

          C. The Board believes that it is imperative to provide the Employee
with certain severance benefits upon Employee's termination of employment
following a Change of Control which provides the Employee with enhanced
financial security and provides incentive and encouragement to the Employee to
remain with the Company notwithstanding the possibility of a Change of Control.

          D. Certain capitalized terms used in the Agreement are defined in
Section 6 below.

          The parties hereto agree as follows:

          1. Term of Agreement. This Agreement shall terminate upon the date
             -----------------
that all obligations of the parties hereto with respect to this Agreement have
been satisfied.

          2. At-Will Employment. The Company and the Employee acknowledge that
             ------------------
the Employee's employment is and shall continue to be at-will, as defined under
applicable law. If the Employee's employment terminates for any reason,
including (without limitation) any termination prior to a Change of Control, 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 Company's established employee plans and
practices or pursuant to other agreements with the Company.

          3.       Severance Benefits.
                   ------------------

                   (a) Involuntary Termination Other than for Cause; Voluntary
                       -------------------------------------------------------
Termination for Good Reason; Disability; Death. If the Employee's employment is
----------------------------------------------
(i) involuntarily terminated by the Company other than for Cause (as defined
herein), (ii) voluntarily terminated by Employee for Good Reason (as defined
herein), (iii) terminated due to Employee's Disability (as defined herein) or
death, in any case within twenty-four (24) months following a Change of Control
(as defined herein), then, subject to the Employee's obligations pursuant to
Section 9 below, the Employee shall receive the following severance benefits
from the Company:

                              (1)  Lump-Sum Severance Payment.  A cash payment
                                   --------------------------
in an amount equal to three hundred percent (300%) of the Employee's Annual
Compensation (as defined herein);

                              (2)  Option Accelerated Vesting. One hundred
                                   --------------------------
percent (100 %) of the unvested portion of any stock option covering Company
shares or shares of any subsidiary of the Company held by the Employee shall
automatically become vested in full upon the employment termination date.

                              (3)  Restricted Stock Accelerated Vesting.
                                   ------------------------------------
Employee's unvested shares granted under the Company's Executive Stock Plan (or
any similar successor plan) shall vest (i.e., be released from the Company's
repurchase option) as to that percentage of the unvested shares determined by
dividing (i) the number of months that have elapsed from the restricted stock
grant date to the date of employment termination, by (ii) the number of months
between the grant date and the date when all shares would otherwise have vested
based on Employee's continued employment with the Company.

                              (4)  Continued Employee Benefits. One hundred
                                   ---------------------------
percent (100%) Company-paid health, dental and life insurance coverage at the
same level of coverage as was provided to such employee immediately prior to the
Change of Control (the "Company-Paid Coverage"). If such coverage included the
Employee's dependents immediately prior to the Change of Control, such
dependents shall also be covered at Company expense. Company-Paid Coverage shall
continue until the earlier of (i) ______ years from the date of termination or
(ii) the date that the Employee and his dependents become covered under another
employer's group health, dental or life insurance plans that provide Employee
and his dependents comparable benefits and levels of coverage. For purposes of
Title X of the Consolidated Budget Reconciliation Act of 1985 ("COBRA"), the
date of the "qualifying event" for Employee and his dependents shall be the date
upon which the Company-Paid Coverage terminates.

                              (5)  Bonus Proration. A lump sum dollar amount
                                   ---------------

fiscal year in which the termination occurs) of Employee's targeted bonus under
the Company's executive bonus plan for the fiscal year in which the termination
occurs.

                                   ------------------
of the Company-owned automobile in Employee's possession at the wholesale Kelly
Blue Book value.

                   (b)  Timing of Severance Payments. Any severance payment to
                        ----------------------------
which Employee is entitled under Sections 3(a)(1 and 5) shall be paid by the
Company to the Employee (or to the Employee's successors in interest, pursuant
to Section 7(b)) in cash and in full, not later than thirty (30) calendar days
following the employment termination date.

                   (c)  Voluntary Resignation other than for Good Reason;
                        ------------------------------------------------
Termination for Cause. If the Employee's employment terminates by reason of the
---------------------
Employee's voluntary resignation other than for Good Reason, or if the Employee
is terminated involuntarily by the Company for Cause, then the Employee shall
not be entitled to receive severance or other benefits except for those (if any)
as may then be established under the Company's then existing severance and
benefits plans and practices or pursuant to other agreements with the Company.

                   (d)  Termination Apart from Change of Control. In the event
                        ----------------------------------------
the Employee's employment is terminated for any reason, either prior to the
occurrence of a Change of Control or after the twenty-four (24) month period
following a Change of Control, then the Employee shall be entitled to receive
severance and any other benefits as may then be established under the Company's
existing severance and benefits plans and practices or pursuant to other written
agreements with the Company.

                   (e)  Non-assumption by Successor Entity. Notwithstanding
                        ----------------------------------
Sections 3(a)(2) and (3) above, if on the effective date of a Change of Control
a successor to the Company (whether direct or indirect and whether by purchase,
merger, consolidation, liquidation or otherwise) to all or substantially all of
the Company's business and/or assets fails to assume any stock option (granted
pursuant to the Company's option plans) or restricted stock (granted pursuant to
the Company's Executive Stock Plan), then (i) one hundred percent (100%) of the
unvested portion of any stock option covering Company shares or the shares of
any subsidiary of the Company held by the Employee shall automatically become
vested in full as of the Change of Control, and (ii) Employee's unvested shares
granted under the Company's Executive Stock Plan shall pro rata vest as outlined
in Section 3(a)(3) above as of the Change of Control.

          4.       Attorney Fees, Costs and Expenses.  The Company shall
                   ---------------------------------
promptly reimburse Employee, on a monthly basis, for the reasonable attorney
fees, costs and expenses incurred by the Employee in connection with any action
brought by Employee to enforce his rights hereunder.

          5.       Golden Parachute Excise Tax Gross-Up. In the event that the
                   ------------------------------------
benefits provided for in this Agreement or otherwise payable to the Employee
constitute "parachute payments" within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended (the "CODE") and will be subject to
the excise tax imposed by Section 4999 (as it may be amended or replaced) of the
Code (the "EXCISE TAX"), then the Employee shall receive (i) a payment from the
Company sufficient to pay such Excise Tax, and (ii) an additional payment from
the Company sufficient to pay the Excise Tax and federal and state income taxes
arising from the payments made by the Company to Employee pursuant to this
sentence. Unless the Company and the Employee otherwise agree in writing, the
determination of Employee's Excise Tax liability and the amount required to be
paid under this Section 5 shall be made in writing by the accounting firm
serving as the Company's

<PAGE>

independent public accountants immediately prior to the Change of Control (the
"ACCOUNTANTS"). For purposes of making the calculations required by this Section
5, the Accountants may make reasonable assumptions and approximations concerning
applicable taxes and may rely on reasonable, good faith interpretations
concerning the application of the Code. The Company and the Employee shall
furnish to the Accountants such information and documents as the Accountants may
reasonably request in order to make a determination under this Section. The
Company shall bear all costs the Accountants may reasonably incur in connection
with any calculations contemplated by this Section 5.

relied upon, shall set forth in reasonable detail the facts and circumstances

                                                         --------
after the Closing, all references in the Retention Agreements to the Company
shall be deemed to constitute references to Purchaser; and from and after the
Closing, no future corporate transactions or events (other than the Closing)
shall be deemed to constitute a Change of Control for purposes of the Retention
Agreements; provided, further, that (i) to the extent, but only to the extent,
            --------  -------
that any such Retention Agreements currently include a provision providing for

Revenue Code of 1986 (a "Gross-Up Provision"), such Gross-Up Provision shall
continue to apply with respect to any future change of control transactions
involving Purchaser and (ii) to the extent that any such Retention Agreements
currently include a provision limiting the dollar amount of the parachute
payments (within the meaning of Section 280G of the Internal Revenue Code of
1986) payable thereunder to the greatest after-tax benefit that can be provided
the individual, such limit shall continue to apply with respect to any future

           (b) The consummation of the transactions contemplated by the Stock

Senior Manager's employment with Seller and commencement of employment with
Purchaser shall not constitute a termination of any Senior Manager's employment
for purposes of the Retention Agreements;

           (i) The term "Good Reason" within the Retention Agreements shall be
restated to mean" an Employee's resignation of his or her employment with the
Company as a result of any of the following actions, which actions remain
uncured for at least thirty (30) days following written notice from Employee to
the Company describing the occurrence of such events and asserting that such

the Company within sixty (60) days after the expiration of such cure period:
without Employee's express written consent, any material reduction in Employee's
authority or responsibilities from those set forth in Employee's employment
agreement with the Company (an "Employment Agreement") (or if such Employee is
not a party to an Employment Agreement, from the authority and responsibilities
initially assigned to such Employee by the Company after the Closing (as defined
in the Stock Purchase Agreement dated as of March 29, 2000 by and between
Seagate Technology, Inc. and Suez Acquisition Company (Cayman) Limited), without
Employee's express written consent, any reduction of 10% or more in the level of
the base salary, target annual bonus or employee benefits to be provided to

an Employment Agreement, a

<PAGE>

reduction of 10% or more in the level of the base salary, target annual
bonus or employee benefits provided to such Employee immediately prior to the
Closing), other than a reduction implemented with the consent of Employee or a
reduction that is equivalent to reduction in base salaries, annual bonus
opportunities and/or employee benefits, as applicable, imposed on all other
senior executives of the Company at a similar level within the Company (provided
that the use of private aircraft shall not be deemed an employee benefit for
theses purposes); or the relocation of Employee to a principal place of
employment more than 50 miles from Employee's current principal place of
employment, without Employee's express written consent"; and

          (c)  The provisions of Sections 3(a)(2) and 3(a)(3) of each of the
Retention Agreements (relating to the accelerated vesting of stock options and
restricted shares) shall only apply with respect to the Rollover Options and
Purchaser Restricted Shares (i.e., options and restricted shares expressly
granted by Purchaser in substitution of (or as a result of Purchaser's
assumption of) unvested options to acquire Seller common stock and unvested
restricted shares which were not otherwise cancelled for consideration in
connection with the Agreement and Plan of Merger by and among Veritas Software
Corporation and Seagate Technology, Inc. dated as of March 29, 2000);

3.        Section  Rollover Equity.
                   ---------------

          (i)  Each Senior Manager agrees to work, in good faith, with Purchaser
and the institutional investors investing in Purchaser at the Closing (the
"Institutional Investors") to provide that Seller Options and/or Seller
Restricted Shares with an aggregate Rollover Value (as defined below) of between
$150,000,000 and $250,000,000 (targeted at $200,000,000) will be converted into
Rollover Options and Purchaser Restricted Shares as follows; provided, that in
any event Seller Options and/or Seller Restricted Shares with an aggregate
Rollover Value of at least $150,000,000 will be so converted: Any such Seller
Options will be assumed by Purchaser and converted into options to acquire
shares of Purchaser and any such Seller Restricted Shares shall be exchanged as
of the Closing Date for the issuance by Purchaser of Purchaser Restricted
Shares, in each case, on the same terms and conditions as were applicable to the
Seller Options and Seller Restricted Shares, as applicable, immediately prior to
the Closing (including any unsatisfied vesting conditions and without any
accelerated vesting as a result of the Closing or any related transactions). For
purposes of this Agreement, "Rollover Value" shall mean with respect to Seller
Options, the excess of (x) the fair market value per share of Seller common
stock (using the average of the Seller's closing selling prices for the five
consecutive trading days ending two trading days immediately preceding the
Closing (the "FMV"), times the number of shares of Seller common stock subject
to the Seller Option, over (y) the aggregate exercise price of the Seller Option
and with respect to Seller Restricted Shares, the FMV times the number of Seller
Restricted Shares.

          (b)  The Purchaser Restricted Shares issued in exchange for Seller
Restricted Shares held by any Senior Manager will have an aggregate fair market
value (determined by reference to the price per share paid by the Institutional
Investors at Closing), as of immediately after Closing, equal to the aggregate
FMV of such cancelled Seller Restricted Shares

<PAGE>

immediately prior to the Closing. Similarly, the conversion of the Seller
Options into Rollover Options will be effected in a manner so as to preserve, as
of the date of assumption and conversion, the "spread" (i.e., the excess of the
FMV per share of Seller common stock immediately prior to the Closing over the
exercise price of the Seller Option).

          (c)  The Senior Managers will work with the Institutional Investors in
good faith to effect the transactions contemplated by this Section 3 in a manner
designed to minimize the application of any excise taxes imposed by Section 280G
of the Internal Revenue Code of 1986.

          (i)  All existing options to acquire common stock of Seller and its
subsidiaries, other than the Seller Options which are assumed by Purchaser and
converted into Rollover Options as contemplated hereby and options to acquire
Seagate Information Management Group Holdings, Inc. common stock which shall
remain outstanding after the Closing; and all existing restricted shares; other
than the Seller Restricted Shares issued in exchange for the issuance of
Purchaser Restricted Shares as contemplated hereby, will be cancelled in
consideration for the payment by Veritas Software Corporation of the merger
consideration pursuant to the terms of the Merger Agreement between Seller and
Veritas Software Corporation.

(ii)           Section Management Term Sheet. In addition to the foregoing,
                       ---------------------
Purchaser and the Senior Managers acknowledge that they have agreed in good
faith to enter into definitive documentation prior to the Closing providing for
the adoption by Purchaser of a new option plan and the grant of options to the
Senior Managers and others, the creation of a management stockholders agreement
governing each Senior Manager's rights and obligations with respect to shares of
Purchaser and other compensation matters, each as set forth more fully in the
Management Term Sheet attached hereto as Exhibit A.

4.        Section  Miscellaneous.
                   -------------

          (a)  This Agreement and the documents and instruments attached hereto
as Exhibits, constitute the entire agreement among the parties with respect to
the subject matter hereof and supercede all prior agreements and understandings,
both written and oral, among the parties with respect to the subject matter
hereof.

          (b)  This Agreement shall be governed by and construed in accordance
with the laws of the State of Delaware, regardless of the laws that might
otherwise govern under applicable principles of conflicts of laws thereof.

          (c)  This Agreement may be executed in one or more counterparts, all
of which shall be considered one and the same agreement, it being understood
that all parties need not sign the same counterpart.
