                             SUN MICROSYSTEMS, INC.

                 VICE PRESIDENT CHANGE OF CONTROL SEVERANCE PLAN

Introduction

         The  Board  of  Directors  of  Sun   Microsystems,   Inc.,  a  Delaware
corporation ("Company"), has evaluated the economic and social impact of certain
acquisitions or change of control events on its employees.  The Board recognized
that it will no longer  have the power to  protect  interests  of the  employees
after an acquisition or other change of control. As a result, the Board believes
that it is in the Company's  interest to provide its employees with the right to
compensation  and  assurance  of  economic  security  in  certain  circumstances
following  an  acquisition  or other change of control.  Furthermore,  the Board
believes  a  severance  compensation  plan of this kind will aid the  Company in
attracting and retaining the highly qualified,  high performing  individuals who
are essential to its success. The plan's assurance of fair treatment will ensure
organizational  stability  during any period of significant  uncertainty that is
inherent to an acquisition or other change of control.

         Accordingly,  the  following  plan has  been  developed  and is  hereby
adopted.


                                   SECTION I.

                              ESTABLISHMENT OF PLAN

         1.1      Establishment of Plan

         As of the Effective  Date, the Company  hereby  establishes a severance
plan to be known as the "Vice President  Change of Control  Severance Plan" (the
"Plan"),  as set forth in this document.  The purposes of the Plan are set forth
in the Introduction.

         1.2      Applicability of Plan

         The benefits  provided by this Plan shall be available to all Employees
of the  Company  who,  at or after  the  Effective  Date,  meet the  eligibility
requirements of Section III.

         1.3      Contractual Right to Benefits

         This Plan establishes and vests in each Participant a contractual right
to the  benefits to which he or she is entitled  hereunder,  enforceable  by the
Participant against his or her Employer or the Company, or both.

         3.2      Re-entry into Plan

                  For purposes of Section 4.3, an individual who ceases to be an
Eligible  Employee  due to a  reduction  in Hours of Work below 20 hours and who
again becomes an Eligible Employee prior to an Change of Control shall be deemed
to have been "continuously  employed" for his or her entire period of employment
as an Eligible Employee.


                                   SECTION IV.

                               SEVERANCE BENEFITS

         4.1      Right to Severance Benefits

                  A Participant  shall be entitled to receive from the Company a
Severance  Payment and certain benefits in the amount and to the extent provided
in this  Section IV if there has been a Change of Control of the Company and if,
within  twelve  (12)  months  thereafter,  the  Participant's  employment  by an
Employer shall  terminate for any reason  specified in Section 4.2,  whether the
termination is voluntary or involuntary.  A Participant shall not be entitled to
a Severance Payment or benefits if termination  occurs for reasons not specified
in Section 4.2, including death,  voluntary retirement at or after age 65, total
and permanent disability, or for Just Cause.


         4.2      Good Reasons for Termination

                  Following a Change of Control, a Participant shall be entitled
to a Severance  Payment and to the benefits  described in Section 4.5  following
termination of employment,  whether voluntary or involuntary, for one or more of
the following reasons:

                  (a) The  Employer  reduces  by 15% or more  the  Participant's
Annual Compensation.

                  (b) The  Employer  reduces  by 20% or more  the  Participant's
Hours of Work as in effect immediately prior to the Change of Control.

                  (c) Without the  Participant's  express written  consent,  the
Employer  requires the  Participant  to change the location of his or her job or
office, so that he or she will be based at a location more than fifty (50) miles
from the  location  of his job or  office  immediately  prior to the  Change  of
Control.

                  (d)  The  cost of  Employer-provided  benefits,  under  plans,
arrangements,  policies and  procedures,  taken as a whole,  decreases by 25% or
more of the Employer-provided cost immediately prior to the Change of Control or
the cost of such  benefits to the  Participant  increases  by 25% or more of the
Participant's cost immediately prior to the Change of Control; provided,

                                       -5-

<PAGE>



however,  that if such increase  results from the Employer's good faith exercise
of better judgment in response to changes in federal or state law, such decrease
increase shall not be a Good Reason for Termination.

                  (e) The Participant  incurs a Significant  Reduction in Duties
and  Responsibilities  as  determined  by the  "Review  Committee".  Such review
Committee  shall be composed of seven (7)  Employees,  appointed by the Board of
Directors for this purpose, of which no less than four (4) are Participants. The
Review  Committee  may establish  such  procedures  as it deems  appropriate  to
facilitate  a  fair  and  objective  review  process  to  determine   whether  a
Participant has incurred a Significant Reduction in Duties and Responsibilities.

                  (f) A  successor  company  fails  or  refuses  to  assume  the
Company's obligations under this Plan, as required by Section VII.

                  (g) The Company or any successor  company  breaches any of the
provisions of this Plan.

                  (h) The Employer terminates the employment of a Participant at
or after a Change of Control other than for Just Cause.

         4.3      Amount of Severance Payment

                  (a) Subject to Section 4.3(b), each Participant  entitled to a
Severance  Payment  under  this Plan who is  employed  by the  Company as of the
Change of Control Date shall receive from the Company a lump sum cash payment in
an amount equal to two (2) times Annual Compensation.

                  (b) In the case of a  Participant  who is not a citizen of the
United States, the Company may, in its discretion,  reduce the Severance Payment
otherwise  calculated  under  Section  4.3(a) by the  amount  of  severance-type
benefits  to which  such  Participant  is then  entitled  under  the laws of the
country in which the Participant resides.

                  (c) A Participant shall not be required to mitigate damages or
the  amount of his or her  Severance  payment  by seeking  other  employment  or
otherwise,  nor shall the amount of such payment be reduced by any  compensation
earned by the Participant as a result of employment after his or her termination
of employment by an Employer.

         4.4      Time of Severance Payment

                  The Severance Payment to which a Participant is entitled shall
be paid by the Company to the  Participant,  in cash and in full,  no later than
ten (10) calendar days after the termination of the Participant's employment. If
such a Participant should die before all amounts payable to him or her have been
paid, such unpaid amounts shall be paid to the Participant's  spouse, if living,
otherwise to the personal representative of the Participant's estate.

         4.5      Other Severance Provisions

                  (a) Subject to the requirements of the Code, Participants will
receive,  in  addition  to  the  Severance  Payment,   the  same  percentage  of
Company-Paid  health and  group-term  life  insurance  in the same plans as were
provided to such Participant immediately prior to the Participant's  termination
(the "Company-Paid  Coverage").  If a Participant's  Company-Paid  Coverage also
included the  Participant's  dependents  immediately  prior to the Participant's
termination, such dependents shall continue to be covered at the same percentage
rate after such termination.

                  (b) Company-Paid  Coverage shall continue for twenty-four (24)
months beginning at the Participant's termination date.

                  (c) For purposes of COBRA, the date of the "qualifying  event"
for Participants  and their covered  dependents shall be the date upon which the
Company-Paid Coverage terminates.

                  (d) In addition to the Severance  Payment and the Company-Paid
Coverage,  all outstanding  options previously granted to Participants under the
Employer's  stock option plans  (including any options issued in substitution or
assumption of such options as a result of a Change in Control),  whether  vested
or  unvested,  shall  have  their  vesting  immediately  accelerated  upon  such
termination;  provided,  however,  that  if it is  determined  by the  Company's
independent public accountants (the  "Accountants") that acceleration of vesting
of option shares would preclude accounting for the acquisition of the Company as
a pooling of  interests,  and it is a condition  to the closing of the Change of
Control  transaction  that the  transaction  be  accounted  for as a pooling  of
interests,  then the  Company  shall  not  accelerate  the  vesting  of  options
hereunder.

         4.6      Parachute Payments

                  (a) In the event that any payment or benefit received or to be
received by a Participant in connection with a termination of the  Participant's
employment with an Employer (collectively, the "Termination Payments") would (i)
constitute an "excess  parachute  payment" within the meaning of Section 280G of
the Code or any similar or successor  provision to Section 280G and (ii) but for
this Section 4.6(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 (c) below, such Termination  Payments (which
Termination   Payments  shall   collectively   be  referred  to  herein  as  the
"Termination  Parachute  Payments") shall be reduced to the largest amount which
would result in no portion of the Termination  Parachute  Payments being subject
to the Excise Tax. In the event any  reduction of benefits is required  pursuant
to this subsection  4.6(a),  each  Participant  shall be allowed to choose which
benefits  hereunder  are  reduced  (e.g.,  reduction  first  from the  Severance
Payment, then from the vesting acceleration).  Any determination as to whether a
reduction  is  required  under this  Section  4.6.  and as to the amount of such
reduction  shall  be  made  in  writing  by  the  Company's  independent  public
accountants  prior  to  the  Change  of  Control  (the   "Accountants"),   whose
determinations  shall be  conclusive  and binding upon the  Participant  and the
Company for all purposes.  For purposes of making the  calculations  required by
this Section 4.6., the

                                       -7-

<PAGE>



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  Participant  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 4.6.

                  (b) If the Internal  Revenue  Service  (the "IRS")  determines
that a  Termination  Parachute  Payment is subject to the Excise  Tax,  then the
Company or any related  corporation,  as their exclusive  remedy,  shall seek to
enforce the provisions of (c) below.  Such  enforcement of Section 4.6(c) hereof
shall be the only remedy, under any and all applicable state and federal laws or
otherwise,  for the failure to reduce the Termination Parachute Payments so that
no portion thereof is subject to the Excise Tax.

                  (c) If,  notwithstanding the reduction described in (a) above,
the IRS  determines  that a Participant is liable for the Excise Tax as a result
of the receipt of a Termination  Parachute Payment, then such Participant shall,
subject to the  provisions of this Plan, be obligated to pay to the Company (the
"Repayment  Obligation") an amount of money equal to the "Repayment Amount". The
Repayment  Amount with respect to a Termination  Parachute  Payment shall be the
smallest such amount,  if any, as shall be required to be paid to the Company so
that such  Participant's net proceeds with respect to any Termination  Parachute
Payment (after taking into account the payment of the Excise Tax imposed on such
Termination   Parachute  Payment)  shall  be  maximized.   Notwithstanding   the
foregoing,  the Repayment Amount with respect to a Termination Parachute Payment
shall be zero if a Repayment  Amount of more than zero would not  eliminate  the
Excise Tax imposed on such Termination  Parachute Payment.  If the Excise Tax is
not  eliminated  through  the  performance  of  the  Repayment  Obligation,  the
participant  shall  pay the  Excise  Tax.  The  Repayment  Obligation  shall  be
performed  within 30 days of either (i) the Participant  entering into a binding
agreement  with the IRS as to the amount of his or her Excise Tax  liability  or
(ii)  a  final  determination  by the  IRS or a  court  decision  requiring  the
Participant  to pay the Excise Tax with respect to such a Termination  Parachute
Payment from which no appeal is available or is timely taken.


                                   SECTION V.

                     OTHER RIGHTS AND BENEFITS NOT AFFECTED

         5.1      Other Benefits

                  Neither the provisions of this Plan nor the Severance  Payment
provided for hereunder shall reduce any amounts otherwise payable, or in any way
diminish  the  Participant's  rights  as an  Employee  of an  Employer,  whether
existing now or  hereafter,  under any  benefit,  incentive,  retirement,  stock
option,  stock bonus, stock purchase plan, or any employment  agreement or other
plan or arrangement.

         5.2      Employment Status

                  THIS PLAN DOES NOT  CONSTITUTE  A CONTRACT  OF  EMPLOYMENT  OR
IMPOSE ON THE PARTICIPANT OR THE PARTICIPANT'S EMPLOYER ANY OBLIGATION TO RETAIN
THE  PARTICIPANT AS AN EMPLOYEE,  TO CHANGE THE STATUS OF THE  PARTICIPANT AS AN
AT-WILL EMPLOYEE,  OR TO CHANGE THE COMPANY'S POLICIES REGARDING  TERMINATION OF
EMPLOYMENT.


                                   SECTION VI.

                             PARTICIPATING EMPLOYERS

         6.1 Upon  approval by the Board of Directors of the Company,  this Plan
may be  adopted  by any  Subsidiary  of the  Company.  Upon such  adoption,  the
Subsidiary  shall become an Employer  hereunder  and the  provisions of the Plan
shall  be  fully  applicable  to the  Employees  of that  Subsidiary.  The  term
"Subsidiary" means any corporation in which the Company,  directly or indirectly
holds a majority of the voting power of its outstanding shares of capital stock.


                                  SECTION VII.

                              SUCCESSOR TO COMPANY

         7.1 The Company shall require any successor or assignee, whether direct
or  indirect,  by  purchase,  merger,  consolidation  or  otherwise,  to  all or
substantially  all  the  business  or  assets  of  the  Company,  expressly  and
unconditionally  to assume and agree to perform the Company's  obligations under

shall be subject to this appeal process. The written appeal must be filed within
sixty (60) days of the employee's termination date.

         The appeal  must state the  reasons  the  employee  or former  employee

provided within ninety (90) days of receiving the written appeal.

         9.3      Review of Appeal Procedure

                  If the appeal of an employee or former employee of an Employer

jurisdiction or by arbitration as set forth in Section 11 hereof.

         10.1 The Company shall pay all legal fees,  costs of litigation  and/or
arbitration,  and other expenses incurred in good faith by each Participant as a

contesting the validity, enforceability or interpretation of the Plan.

rules of the American  Arbitration  Association then in effect.  Judgment may be
entered on the award of the  arbitrator  in any court having  jurisdiction.  All
expenses of such arbitration, including the fees and expenses of the counsel for
the Participant, shall be borne by the Company.
