                                                                   EXHIBIT 10.12

                            CONNER PERIPHERALS, INC.

                     CHANGE OF CONTROL SEVERANCE AGREEMENT



  This Change of Control Severance Agreement (the "Agreement") is made and
entered into by and between _____________________ (the "Employee") and Conner
Peripherals, Inc., a Delaware corporation (the "Company"), effective as of
____________________________________.

                                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
stockholders 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 4
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) Termination Following A Change of Control.  If the Employee's
employment terminates at any time within twenty-four (24) months following a
Change of Control, then, subject to Section 4, the Employee shall be entitled to
receive the following severance benefits:

          (i) Involuntary Termination.  If the Employee's employment is
terminated as a result of Involuntary Termination other than for Cause, then the
Employee shall receive the following severance benefits from the Company:

               (1) Severance Payment.  A cash payment in an amount equal to one
hundred percent (100%) of the Employee's Annual Compensation;

               (2) 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) one year 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
with 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.

               (3) Option and Restricted Stock Accelerated Vesting.  Fifty
percent (50%) of the unvested portion of any stock option or restricted stock
held by the Employee shall automatically be accelerated in full so as to become
completely vested; provided, however, that if such potential vesting
acceleration would cause a contemplated Change of Control transaction that was
intended to be accounted for as a "pooling-of-interests" transaction to become
ineligible for such accounting treatment under generally accepted accounting
principles, as determined by the Company's independent public accountants (the
"ACCOUNTANTS") prior to the Change of Control, Employee's stock options and
restricted stock shall not have their vesting so accelerated.

               (4) Extension of Post-Termination Exercise Period of Nonstatutory
Stock Options.  The nonstatutory stock options held by Employee shall become
exercisable for a period of three months following Employee's termination of
employment or consulting relationship with the Company.

     (b) Timing of Severance Payments.  Any severance payment to which Employee
is entitled under Section 4(a)(1) 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 Termination
Date.

                                      -2-

 
     (c) Voluntary Resignation; Termination For Cause.  If the Employee's
employment terminates by reason of the Employee's voluntary resignation (and is
not an Involuntary Termination), or if the Employee is terminated 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) Disability; Death.  If the Company terminates the Employee's employment
as a result of the Employee's Disability, or such Employee's employment is
terminated due to the death of the Employee, 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.

     (e) 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 only as may then be established under the Company's existing
severance and benefits plans and practices or pursuant to other agreements with
the Company.

  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.  In the event Employee is not the
prevailing party, determined without regard to whether or not the action results
in a final judgment, Employee shall repay such reimbursements.

  5. LIMITATION ON PAYMENTS.  In the event that the severance and other benefits
provided for in this Agreement or otherwise payable to the Employee (i)
constitute "parachute payments" within the meaning of Section 280G of the
Internal Revenue Code of 1986, as amended (the "Code") and (ii) but for this
Section 5, would be subject to the excise tax imposed by Section 4999 of the
Code, then the Employee's severance benefits under Section 3(a)(i) shall be
either

     (a) delivered in full, or

     (b) delivered as to such lesser extent which would result in no portion of
         such severance benefits being subject to excise tax under Section 4999
         of the Code,

whichever of the foregoing amounts, taking into account the applicable federal,
state and local income taxes and the excise tax imposed by Section 4999, results
in the receipt by the Employee on an after-tax basis, of the greatest amount of
severance benefits, notwithstanding that all or some portion of such severance
benefits may be taxable under Section 4999 of the Code.  Unless the Company and
the Employee otherwise agree in writing, any determination required under this
Section 5 shall be made in writing by the Company's independent public
accountants immediately prior to Change of Control 

                                      -3-

 
(the "Accountants"), whose determination shall be conclusive and binding upon
the Employee and the Company for all purposes. 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 Sections
280G and 4999 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.

  6. DEFINITION OF TERMS.  The following terms referred to in this Agreement
shall have the following meanings:

     (a) Annual Compensation.  "Annual Compensation" means an amount equal to
(i) Employee's Company salary for the twelve months preceding the Change of
Control, and (ii) Employee's maximum target bonus for the year in which the
Change of Control occurs.

     (b) Cause.  "Cause" shall mean (i) any act of personal dishonesty taken by
the Employee in connection with his responsibilities as an employee and 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 and which is injurious to the Company, and (iv)  following
delivery to the Employee of a written demand for performance from the Company
which describes the basis for the Company's belief that the Employee has not
substantially performed his duties, continued violations by the Employee of the
Employee's obligations to the Company which are demonstrably willful and
deliberate on the Employee's part.

     (c) Change of Control.  "Change of Control" means 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 13d-3 under said Act), directly or indirectly, of
securities of the Company representing 50% or more of the total voting power
represented by the Company's then outstanding voting securities; or

         (ii) A change in the composition of the Board occurring within a two-
year 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 Company as of the date hereof, or (B) are elected, or
nominated for election, to the Board 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 Company); or

        (iii) The stockholders of the Company approve a merger or consolidation
of the Company with any other corporation, other than a merger or consolidation
which would result 

                                      -4-

 
in the voting securities of the Company 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 Company or
such surviving entity outstanding immediately after such merger or
consolidation, or the stockholders of the Company approve a plan of complete
liquidation of the Company or an agreement for the sale or disposition by the
Company of all or substantially all the Company's assets.

     (d) Disability.  "Disability" shall mean that the Employee has been unable
to perform his Company duties as the result of his incapacity due to physical or
mental illness, and such inability, at least 26 weeks after its commencement, is
determined to be total and permanent by a physician selected by the Company or
its insurers and acceptable to the Employee or the Employee's legal
representative (such Agreement as to acceptability not to be unreasonably
withheld).  Termination resulting from Disability may only be effected after at
least 30 days' written notice by the Company 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.

     (e) Involuntary Termination.  "Involuntary Termination" shall mean (i)

responsibilities; (ii) without the Employee's express written consent, a
substantial reduction, without good business reasons, of the facilities and
perquisites (including office space and location) available to the Employee
immediately prior to such reduction; (iii) a reduction by the Company in the
base salary of the Employee as in effect immediately prior to such reduction;
(iv) a material reduction by the Company in the kind or level of employee
benefits, including bonuses, to which the Employee was 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 thirty (30) miles from the Employee's then
present location, without the Employee's express written consent; (vi) any
purported termination of the Employee by the Company which is not effected for
Disability or for Cause, or any purported termination for which the grounds
relied upon are not valid; (vii) the failure of the Company to obtain the
assumption of this agreement by any successors contemplated in Section 7(a)
below; or (viii) any act or set of facts or circumstances which would, under
California case law or statute constitute a constructive termination of the
Employee.

     (f) Termination Date.  "Termination Date" shall mean (i) if this Agreement
is terminated by the Company for Disability, thirty (30) days after notice of
termination is given to the Employee (provided that the Employee shall not have
returned to the performance of the Employee's duties on a full-time basis during
such thirty (30)-day period), (ii) if the Employee's employment is terminated by
the Company for any other reason, the date on which a notice of termination is
given, provided that if within thirty (30) days after the Company gives the
Employee notice of termination, the Employee notifies the Company that a dispute
exists concerning the termination or the benefits 

                                      -5-

 
due pursuant to this Agreement, then the Termination Date shall be the date on
which such dispute is finally determined, either by mutual written agreement of
the parties, or a by final judgment, order or decree of a court of competent
jurisdiction (the time for appeal therefrom having expired and no appeal having
been perfected), or (iii) if the Agreement is terminated by the Employee, the
date on which the Employee delivers the notice of termination to the Company.

  7. SUCCESSORS.

     (a) Company's Successors.  Any 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
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 Company would be required to perform such obligations in the absence of a
succession.  For all purposes under this Agreement, the term "Company" shall
include any successor to the Company's business and/or assets which executes and
delivers the assumption agreement described in this Section 7(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.

  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 Company in writing. In the case of the Company, mailed
notices shall be addressed to its corporate headquarters, and all notices shall
be directed to the attention of its Secretary.

     (b) Notice of Termination.  Any termination by the Company for Cause or by
the Employee as a result of a voluntary resignation or an Involuntary
Termination shall be communicated by a notice of termination to the other party
hereto given in accordance with Section 8(a) 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 30 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.

                                      -6-

 
  9. MISCELLANEOUS PROVISIONS.

the amount of any payment contemplated by this Agreement, 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 Company (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 as applied to agreements entered into and performed within California
solely by residents of that state.

     (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) Withholding.  All payments made pursuant to this Agreement will be
subject to withholding of applicable income and employment taxes.

     (g) Counterparts.  This Agreement may be executed in counterparts, each of
which shall be deemed an original, but all of which together will constitute one
and the same instrument.

                                      -7-

 
     IN WITNESS WHEREOF, each of the parties has executed this Agreement, in the
case of the Company by its duly authorized officer, as of the date set forth
above.
