                                    FORM OF
                              STOCKHOLDER AGREEMENT


        This Stockholder Agreement (the "AGREEMENT") is entered into as of
__________, 1999, (the "EFFECTIVE DATE") by and among VERITAS Software
Corporation, a Delaware corporation ("VERITAS"), VERITAS Holding Corporation, a
Delaware corporation ("NEWCO"), Seagate Technology, Inc., a Delaware corporation
("STI"), and Seagate Software, Inc., a Delaware corporation ("SSI", and
collectively with STI and STI's other controlled subsidiaries, "SEAGATE").


                                    RECITALS

        A. The parties have entered into an Agreement and Plan of Reorganization
(the "PLAN") whereby (i) a newly formed, wholly owned subsidiary of Newco
("NEWCO VERITAS MERGER SUB") will be merged with and into VERITAS, with VERITAS
being the surviving corporation of such merger (the "VERITAS MERGER"); (ii) all
VERITAS securities will be converted, share-for-share, into Newco securities
with identical rights, preferences and privileges (and Newco will assume all
outstanding options, warrants, convertible debentures and other rights to
purchase shares of capital stock of VERITAS); and (iii) Seagate will transfer to
Newco all assets used in connection with the business previously carried on by
Seagate's Network & Storage Management Group ("NSMG"), in consideration for
which Newco will issue Newco securities to SSI and offer to issue Newco
securities to former NSMG employees holding options to purchase SSI securities,
which Newco securities in the aggregate will represent approximately 40% of the
fully diluted equity securities of Newco (collectively, the "REORGANIZATION").

        B. As an inducement for Newco to enter into the Plan, the parties desire
to enter into this Agreement, which shall become effective on the effective date
of the Reorganization and, among other things, grants Seagate certain rights and
places certain restrictions on Seagate and on the Newco securities that Seagate
now holds or hereafter acquires.

        NOW, THEREFORE, in consideration of the above recitals and the mutual
covenants hereinafter set forth, the parties hereby agree as follows:

        1. BOARD OF DIRECTORS

                1.1 APPOINTMENTS. Upon the closing of the Plan, Newco shall
increase the size of its Board of Directors (the "NEWCO BOARD") to ten persons
and appoint Terence R. Cunningham and two designees of Seagate, Stephen J.
Luczo, and Greg Kerfoot, as members of the Newco Board.

                1.2 TWO DESIGNEES. For so long as Seagate owns at least 15% of
the outstanding Common Stock of Newco, Newco and its Board of Directors shall
nominate, in connection with each stockholder solicitation relating to the
election of Newco directors, two candidates designated by Seagate who are
reasonably acceptable to Newco.



<PAGE>   2

                1.3 ONE DESIGNEE. For so long as Seagate owns at least 5% and
not more than 15% of the outstanding Common Stock of Newco, Newco and its Board
of Directors shall nominate, in connection with each stockholder solicitation
relating to the election of Newco directors, one candidate designated by Seagate
who is reasonably acceptable to Newco.

                1.4 AFFILIATES. For purposes of this Agreement, all shares held
by an entity or person controlling, controlled by or under common control with
Seagate will be deemed to be owned by Seagate.

                1.5 VOTING OF MANAGEMENT SHARES. Newco shall use its best
efforts (i) to cause the Newco Board to unanimously recommend to its
stockholders that such stockholders vote in favor of the designee(s) of Seagate
under Section 1.2 or 1.3 of this Agreement (the "SEAGATE DESIGNEE(S)"); and (ii)
to cause the shares for which Newco's management holds proxies to be voted in
favor of the election of such Seagate Designee(s) nominated pursuant to this
Agreement.

                1.6 VACANCIES. In the event that any Seagate Designee shall
cease to serve as a member of the Board of Directors of Newco for any reason,
the vacancy resulting therefrom shall be filled by another Seagate Designee.

                1.7 EQUAL TREATMENT. Newco shall provide to the Seagate
Designee(s) that are not employees of Newco the same compensation, rights and
benefits and indemnities as are provided to other non-employee members of the
Newco Board.

                1.8 PARTICIPATION ON BOARD COMMITTEES. At the Effective Date,
Newco will have two committees of the Board of Directors: a Compensation
Committee and an Audit Committee.

                1.9 STAGGERED BOARD OF DIRECTORS. At the Effective Date, Newco's
Board of Directors shall be classified into three classes consisting of Classes
A, B and C, with each class serving for staggered three year terms. As an
initial matter, the Directors in Class A will serve for a term ending at Newco's
annual meeting of stockholders in 1999; the Directors in Class B will serve for
a term ending at Newco's annual meeting of stockholders in 2000; and the
Directors in Class C will serve for a term ending at Newco's annual meeting of
stockholders in 2001. At the Effective Date, the class A Directors shall consist
of Gregory Kerfoot, Geoffrey Squire and Roel Pieper; the Class B Directors shall
consist of Mark Leslie, Joseph Rizzi, William Janeway and Terence R. Cunningham;
and the Class C Directors shall consist of Stephen Brooks, Fred van den Bosch
and Stephen J. Luczo.

                1.10 TERMINATION. All rights and obligations under this Section
1 shall terminate and have no further force or effect immediately upon Seagate
ceasing to hold at least 5% of the outstanding Common Stock of Newco.

        2. RESTRICTIONS UPON TRANSFER OF SHARES

                2.1 PERMITTED SALES OF NEWCO STOCK. For so long as Seagate owns
(of record or beneficially) at least 5% of the outstanding Common Stock of
Newco, Seagate shall not sell, 




                                      -2-
<PAGE>   3

transfer, assign, pledge, hypothecate or otherwise dispose of any interest in
any Newco securities, directly or indirectly, for a period of one year following
the consummation of the Plan, except as provided in Section 2.2 below, and
thereafter shall not so dispose of any Newco securities except (i) to Newco or
to a person or persons that Newco has previously approved in writing; (ii)
pursuant to a Bona Fide Public Offering (as defined below); (iii) pursuant to
Rule 144 under the Securities Act of 1933, as amended (the "SECURITIES ACT");
(iv) in other private transactions so long as such private transactions do not
result, to the knowledge of Seagate, in any single person or group owning 5% or
more of the total outstanding voting stock of Newco; (v) in response to a tender
offer not opposed by the Newco Board; (vi) in a merger or consolidation approved
by the Newco Board in which Newco is acquired; or (vii) pursuant to a plan of
liquidation that is authorized by the Newco Board. As used in this Agreement,
"BONA FIDE PUBLIC OFFERING" means a firm commitment underwritten public offering
of Newco equity or convertible debt securities registered under the Securities
Act in which Newco securities are offered to a broad range of investors and
which registration has been declared effective by the Securities and Exchange
Commission.
                2.2 PERMITTED SALES DURING FIRST YEAR. Seagate may sell (a) up 
to a maximum number of 6,000,000 shares of Newco Common Stock in one Bona Fide 
Public Offering in the first year following consummation of the Plan, and (b) 
in any quarter in which the Bona Fide Public Offering referred to in clause (a) 
above has not been completed, Newco Common Stock according to the following 
schedule: (i) up to a maximum number of 2,000,000 shares in the quarters ending 
in September, 1999, December, 1999 and March, 2000, and (ii) up to a maximum 
number of 3,000,000 shares in the quarter ending in June, 2000. Newco shall pay 
all expenses incurred in connection with a Bona Fide Public Offering pursuant 
to this Section including, without limitation, all registration and filing
fees, printing expenses, custody fees, fees and disbursements of counsel for
Newco, blue sky fees and expenses, and the expense of any special audits
incident to or required by any such Bona Fide Public Offering but not including
any underwriting discounts and selling commissions applicable to the sale of the
shares and all fees and disbursements of counsel for Seagate.
        3. VOTING PROVISIONS.

                3.1 PROPORTIONAL VOTING. For so long as Seagate owns (of record
or beneficially) at least 5% of the outstanding Common Stock of Newco in
connection with all matters to be voted on by the stockholders of Newco, Seagate
shall vote all shares of Newco Common Stock then owned, directly or indirectly,
by it in the same proportion as the votes cast by all other holders of Newco's
Common Stock, except that Seagate may vote its shares as it determines in its
sole discretion as to the following specific matters: (i) a change in the
Fundamental Rights (as defined below) of Newco Common Stock; and (ii) a
recapitalization in which Newco Common Stock is converted or exchanged for a
security having substantially different Fundamental Rights than Newco Common
Stock (but in all events excluding any recapitalization or reorganization
accomplished in connection with a Corporate Event). A "CORPORATE EVENT" shall
include any merger, acquisition, consolidation or reorganization, any
transaction of a type contemplated by Section 351 of the Internal Revenue Code
of 1986, as amended (the "CODE") or any other similar transaction whereby (a)
Newco is acquired by a third party, (b) where there has been a "change of
control" such that the stockholders of Newco prior to a transaction own, in the
aggregate, less than a majority of the outstanding stock of Newco or the
acquiring entity after the transaction, (c) Newco acquires another entity, or
(d) Newco acquires all or substantially all of the assets of another entity.
"FUNDAMENTAL RIGHTS" shall mean the right to vote Newco's shares and to
participate pro rata with other holders of Newco Common Stock in any
distribution to the holders of Newco Common Stock.

                3.2 NO DISSENT. For so long as Seagate owns (of record or
beneficially) at least 5% of the outstanding Newco Common Stock, Seagate agrees
that it will not exercise dissenter's or appraisal rights or otherwise dissent
or seek appraisal rights with respect to any Corporate Event involving Newco
that has been approved by the Newco Board.

        4. STANDSTILL PROVISIONS.

                4.1 STANDSTILL. Seagate hereby agrees that, until the fifth
anniversary of the Effective Date, Seagate will not, without Newco's prior
written consent:

                (i) acquire, or enter into discussions, negotiations,
arrangements or understandings with any third party to acquire, beneficial
ownership (as defined in Rule 13d-3 promulgated under the Securities Exchange
Act of 1934, as amended (the "EXCHANGE Act")) of any Newco securities entitled
to vote with respect to the election of any directors of Newco ("VOTING STOCK"),
any securities convertible into, exchangeable for or exerciseable for, or that
may otherwise become, Voting Stock, or any other right to acquire Voting Stock,
if the effect of such acquisition would be that Seagate would then beneficially
own and/or have the right to acquire more than [__] percent (__%) of the Voting
Stock [THIS WILL BE THE PERCENTAGE OF VOTING STOCK HELD BY SEAGATE AS OF THE
EFFECTIVE DATE] (the "STANDSTILL PERCENTAGE");

                (ii) make, or in any way participate in, any "solicitation" of
"proxies" (as such terms are defined or used in Regulation 14A under the
Exchange Act, as such Regulation is currently in effect) with respect to the
voting of any Voting Stock if Newco is at the time of such solicitation
publicly-traded and subject to the proxy rules promulgated under the Exchange
Act; or

                (iii) otherwise seek, either alone or in concert with others, to
control the Newco Board or the policies of Newco.

Notwithstanding the foregoing, nothing herein shall limit Seagate's ability to
exercise its rights under Section 5 hereof. For purposes of this Section 4, any
shares of Newco Common Stock or options or rights to acquire such Newco Common
Stock acquired by Seagate Affiliates who are also employees or directors of
Newco pursuant to Newco's option and employee stock purchase plans (including
any options to purchase Newco securities issued to such persons under the terms
of the Plan) shall be excluded from the calculation of the number of shares of
Voting Stock held by Seagate.

                4.2 EXCEPTIONS TO STANDSTILL. Notwithstanding the restrictions
set forth in Section 4.1 above:

                        (a) ACQUISITIONS. Seagate may acquire Voting Stock, and
the limitations of Section 4.1 shall be suspended, upon the earlier of: (i) the
date that a third party not affiliated with Seagate commences a tender or
exchange offer that is made and is not withdrawn or terminated to purchase, or
to exchange for cash or other consideration, Voting Stock that, if accepted or
if otherwise successful, would result in such person or group beneficially
owning or having the right to acquire shares of Voting Stock (not counting any
shares of Voting Stock originally acquired by such third party from Seagate or
any Seagate Affiliate) with aggregate Voting Power (as defined below)
representing more than 50% of the Total Voting Power (as defined below) of Newco
then in effect provided, however, that the foregoing standstill limitation will
be reinstated if any such tender or exchange offer is withdrawn or terminated,
(ii) the public announcement by Newco that it has entered into any agreement
with respect to a merger, consolidation, reorganization or similar transaction
involving Newco in which all the 




                                      -4-
<PAGE>   5

stockholders of Newco before such transaction collectively will own less than
50% of the outstanding voting stock of the surviving or acquiring entity
immediately after such transaction provided, however; that the foregoing
standstill limitation will be reinstated if such transaction is terminated prior
to consummation thereof, or (iii) the sale or disposition of all or
substantially all of Newco's assets.

                        (b) NO OBLIGATION TO DISPOSE. Seagate will not be
obliged to dispose of any Voting Stock to the extent that the aggregate
percentage of the Total Voting Power represented by shares of Voting Stock
beneficially owned by Seagate or which Seagate has a right to acquire is
increased beyond the Standstill Percentage: (i) as a result of a
recapitalization of Newco or a repurchase or exchange of securities by Newco or
any other action taken by Newco or its affiliates; (ii) as the result of any
acquisition of Voting Stock made during the period when Seagate's "standstill"
obligations are suspended pursuant to Section 4.2(a); (iii) by way of stock
dividend or other distribution or rights or offerings made available to holders
of shares of Voting Stock generally; (iv) with the consent of a simple majority
of the [members of Newco's Board of Directors that have not been designated by
Seagate; or (v) as part of a transaction on behalf of Seagate's Profit Sharing
Retirement Plan, 401(k) Savings Plan, or any successor or additional retirement
plans thereto (collectively, the "RETIREMENT PLANS") where Newco shares in such
Retirement Plans are voted by a trustee for the benefit of Seagate employees or,
for those Retirement Plans where Seagate controls voting, where Seagate agrees
that any shares of Voting Stock in such Retirement Plans will be subject to the
Voting Provisions of Section 3 hereof.

                        (c) VOTING POWER. As used in this Section 4, (i) the
term "VOTING POWER" means the number of votes such Voting Stock is entitled to
cast with respect to the election of directors of Newco at any meeting of
stockholders of Newco; and (ii) the term "TOTAL VOTING POWER" means the total
number of votes which may be cast in the election of directors of Newco at any
meeting of stockholders of Newco if all Voting Stock was represented and voted
to the fullest extent possible at such meeting, other than votes that may be
cast only upon the happening of a contingency that has not occurred.

For purposes of this Section 4, "SEAGATE" shall mean not only Seagate, as
defined in the preamble of this Agreement, but also any entity or person
controlling, controlled by or under common control with Seagate (except as set
forth in the last paragraph of Section 4.1).

        5. RIGHT TO MAINTAIN.

                5.1 GENERAL. If Newco is contemplating the issuance of Dilutive
Securities (as defined in Section 5.2 below) to a third party (including but not
limited to a customer, supplier, developer or reseller) as part of a strategic
business relationship with such third party (a "STRATEGIC CUSTOMER"), SSI will
have the right, pursuant to the terms and conditions of this Section 5, to
purchase from Newco the same Dilutive Securities as are issued by Newco to the
Strategic Customer ("MAINTENANCE SECURITIES") at the Purchase Price (as defined
in Section 5.3) following the issuance by Newco of such securities to the
Strategic Customer, solely in order to maintain SSI's Prior Percentage Interest
(as defined in Section 5.4) in Newco (the "RIGHT OF MAINTENANCE"). Each right to
purchase Maintenance Securities pursuant to this Section 5 shall 




                                      -5-
<PAGE>   6

be on the same terms (other than price to the extent provided in Section 5.3
below) as the issuance of securities which gave rise to the right to purchase
such Maintenance Securities.

                5.2 DILUTIVE SECURITIES. "DILUTIVE SECURITIES" shall mean any
Common Stock, Preferred Stock or voting capital stock of Newco, whether or not
now authorized, which is issued to a Strategic Customer; provided, however, that
the term "Dilutive Securities" does not include: 

                        (a) any Common Stock, Preferred Stock or other capital
stock issued upon exercise of any options or warrants or upon conversion of any
debentures or other convertible securities outstanding as of the date hereof;

                        (b) any Common Stock, Preferred Stock or other capital
stock issued to employees, directors, consultants or advisors, pursuant to
incentive agreements, plans or arrangements approved by the Newco Board; 

                        (c) any securities (including Common Stock, Preferred
Stock, capital stock or convertible debt securities) issued in connection with a
Bona Fide Public Offering; 

                        (d) any securities issued in connection with any stock
split, stock dividend or similar event in which SSI is entitled to participate
on a proportionate basis; or 

                        (e) any securities issued in connection with any
Corporate Event.

                5.3 PURCHASE PRICE.

                        (a) GENERAL. The per share "PURCHASE PRICE" of the
Maintenance Securities shall equal the per share price at which such Dilutive
Securities were issued, unless the issuance of such other Dilutive Securities
occurred upon the exercise, conversion or exchange of other securities
("EXCHANGEABLE SECURITIES"), in which case, the per share "Purchase Price" of
the Maintenance Securities shall equal the sum of (i) the per share amounts paid
upon each such exercise, conversion or exchange, and (ii) the per share amount
previously paid for the Exchangeable Securities (adjusted for any stock splits,
stock dividends or other similar events).

                        (b) CONSIDERATION OTHER THAN CASH. In the event that
Dilutive Securities or Exchangeable Securities were issued for consideration
other than cash, the per share amounts paid for such Dilutive Securities or
Exchangeable Securities shall be determined jointly by Newco and SSI.

                        (c) APPRAISER. If Newco and SSI are unable to reach
agreement within a reasonable period of time with respect to (i) the fair market
value of unlisted securities (the "MARKET PRICE"); or (ii) the per share amounts
paid for Dilutive Securities or Exchangeable Securities issued for consideration
other than cash, such Market Price or per share amounts paid, as the case may
be, shall be determined by an appraiser jointly selected by Newco and SSI. The
determination of such appraiser shall be final and binding on Newco and SSI. The
fees and expenses of such appraiser shall be paid by Newco, provided that such
fees and expenses shall be paid by SSI in the event that the appraiser's
determination of the Market Price or the per share 




                                      -6-
<PAGE>   7

amounts paid, as the case may be, is higher than, or no more than 5% lower than,
the last amount previously offered by Newco.

                5.4 PRIOR PERCENTAGE INTEREST. SSI's "PRIOR PERCENTAGE INTEREST"
for purposes of the Right of Maintenance is the ratio of (a) the number of
shares of Common Stock held by SSI as of the date of such Maintenance Notice (as
defined in Section 5.6) (the "NOTICE DATE") that represent shares that SSI
purchased pursuant to (i) the Plan, and (ii) prior exercises of the Right of
Maintenance, to (b) the total number "Common Stock Equivalents" (as defined
below) of Newco outstanding immediately prior to the issuance of the Dilutive
Securities. The total number of Common Stock Equivalents of Newco shall be
calculated assuming the conversion of all outstanding options, warrants and
convertible debentures to Common Stock; provided, however, that the total number
of shares subject to outstanding options (but not the number of shares issuable
upon the exercise of convertible debentures) shall be calculated on the Treasury
Method.

                5.5 MAINTENANCE AMOUNT. SSI's "MAINTENANCE AMOUNT" with respect
to any Maintenance Notice shall equal such number of Maintenance Securities as
is obtained by multiplying the number of Dilutive Securities specified in such
Maintenance Notice by SSI's Prior Percentage Interest, rounded to the nearest
whole share.

                5.6 NOTICE OF ISSUANCE. Within 15 business days of each issuance
of Dilutive Securities, Newco shall give to SSI written notice (the "MAINTENANCE
NOTICE") describing the number of Dilutive Securities issued since such prior
Notice Date and the terms upon which Newco issued such Dilutive Securities, and
the Maintenance Amount of Maintenance Securities that SSI is entitled to
purchase as a result of such issuance.

                5.7 PURCHASE OF MAINTENANCE SECURITIES. SSI shall have 15
business days from the receipt of a Maintenance Notice to elect to purchase up
to SSI's Maintenance Amount of such Maintenance Securities at the Purchase Price
as defined in Section 5.3 and upon the terms and conditions specified in the
Maintenance Notice. The closing of such purchase shall occur within 5 business
days after such election to purchase. If SSI fails to elect to purchase SSI's
full Maintenance Amount of Maintenance Securities within such 15 business day
period, then SSI shall forfeit the right hereunder to purchase that part of
SSI's Maintenance Amount that it did not so elect to purchase.

                5.8 TERMINATION. The Right of Maintenance shall terminate upon
the earlier of (i) the third anniversary of the Effective Date; or (ii) such
time as Seagate ceases to own at least ten percent of the outstanding Common
Stock of Newco.
