                                     WARBURG



         STOCK VOTING AGREEMENT (this "Agreement"),  dated as of October 8, 1998
by and between WARBURG,  PINCUS CAPITAL COMPANY,  L.P ("Stockholder") and INACOM
CORP., a Delaware  corporation  ("Parent") and VANSTAR  CORPORATION,  a Delaware
corporation (the "Company").

         WHEREAS,  concurrently  herewith,  Parent, Parent Sub, Inc., a Delaware
corporation and a wholly owned  subsidiary of Parent (the "Parent Sub"), and the
Company, are entering into an Agreement and Plan of Merger of even date herewith
(such  Agreement  in the form  attached  hereto as Exhibit "A" being the "Merger
Agreement"),  pursuant to which the Parent Sub will merge with and into  Company
(the "Merger"); and

         WHEREAS,  Stockholder owns, as of the date hereof, 16,288,691 shares of
common stock,  $.001 par value per share of the Company ("Company Common Stock")
(such shares of Company Common Stock owned by Stockholder on the date hereof are
herein  referred to as the  "Existing  Shares" and,  together with any shares of
Company Common Stock acquired by the Stockholder after the date hereof and prior
to  the  termination  hereof,   hereinafter  collectively  referred  to  as  the
"Shares"); and

         WHEREAS,  the Board of  Directors  of the  Company  has  approved  this
Agreement and the transactions contemplated hereby; and

         WHEREAS,  Parent and Parent Sub have entered into the Merger  Agreement
in  reliance  on  and  in  consideration   of   Stockholder's   representations,
warranties, covenants and agreements hereunder.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration,  and intending to be
legally bound hereby, it is agreed as follows:

         1. Agreement to Vote.  Stockholder  hereby revokes any and all previous
proxies with respect to the Shares and irrevocably  agrees to vote and otherwise
act (including  pursuant to written  consent) with respect to all of the Shares,
for the approval and the  adoption of the Merger  Agreement,  as the same may be
amended from time to time, all agreements  related to the Merger and any actions
related thereto,  at any meeting or meetings of the stockholders of the Company,
and at any  adjournment,  postponement  or  continuation  thereof,  at which the
Merger  Agreement  and other  related  agreements  (or any  amended  version  or
versions thereof), or such other actions are submitted for the consideration and
vote of the stockholders of the Company.  At Parent's  request,  the Stockholder
will deliver to Parent an irrevocable proxy (the "Irrevocable  Proxy") only with
respect  to the  matters  covered  by this  Section  granting  to  Parent or its
designee a proxy to vote the Shares in accordance with the terms of this Section
1; provided, that such proxy shall survive only until, and shall terminate upon,
the earlier to occur of the Effective Time (as defined in the Merger  Agreement)
or the termination of the Merger Agreement. The obligations of Stockholder under
this  Section 1 shall  remain in effect with  respect to the Shares  until,  and
shall  terminate  upon,  the  earlier  to  occur  of the  Effective  Time or the
termination of the Merger Agreement.  Stockholder  hereby agrees to execute such
additional  documents  as  Parent  may  reasonably  request  to  effectuate  the
foregoing.

         2.       Representations  and  Warranties of  Stockholder.  Stockholder
                  represents and warrants to Parent as follows:

         2.1      Ownership of Shares.  On the date hereof,  the Existing Shares
                  are  all  of  the  Shares   currently  owned  by  Stockholder.
                  Stockholder  currently  has,  and at  Closing  will have good,
                  valid and  marketable  title to the Shares,  free and clear of
                  all liens,  encumbrances,  and security  interests (other than
                  the  encumbrances  created  by this  Agreement  and other than
                  restrictions  on transfer under  applicable  Federal and State
                  securities  laws)  and  free of other  restrictions,  options,
                  rights to purchase or other claims that would adversely affect
                  the  ability  of  Stockholder   to  perform  its   obligations
                  hereunder or pursuant to which,  Stockholder could be required
                  to sell, assign or otherwise transfer the Shares.

         2.2      Authority;  Binding Agreement.  Stockholder has the full legal
                  right,  power and  authority  to enter into and perform all of
                  its obligations under this Agreement.  This Agreement has been
                  duly executed and delivered by Stockholder  and  constitutes a
                  legal, valid and binding agreement of Stockholder, enforceable
                  in  accordance  with  its  terms,  except  as the  enforcement
                  thereof   may   be   limited   by   bankruptcy,    insolvency,
                  reorganization,  moratorium and similar laws, now or hereafter
                  in effect affecting creditors rights and remedies generally or
                  general  principles  of  equity.  Neither  the  execution  and
                  delivery of this Agreement nor the consummation by Stockholder
                  of the transactions  contemplated  hereby will (i) violate, or
                  require any consent,  approval or notice under,  any provision
                  of  any  judgment,   order,  decree,  statute,  law,  rule  or
                  regulation  applicable  to  Stockholder  or the Shares or (ii)
                  constitute  a violation  of,  conflict  with or  constitute  a
                  default   under,   any   contract,   commitment,    agreement,
                  understanding, arrangement or other restriction of any kind to
                  which Stockholder is a party or by which Stockholder is bound,
                  in each case the effect of which  would  adversely  affect the
                  ability of Stockholder to perform its obligations hereunder.

         2.3      Reliance   on   Agreement.    Stockholder    understands   and
                  acknowledges  that the Parent Sub and Parent each are entering
                  into the  Merger  Agreement  in  reliance  upon  Stockholder's
                  execution   and  delivery  of  this   Agreement.   Stockholder
                  acknowledges  that the  agreement  set  forth in  Section 1 is
                  granted in consideration for the execution and delivery of the
                  Merger Agreement by the Parent Sub and Parent.

         3.       Certain  Covenants of  Stockholder.  Except in accordance with
                  the provisions of this Agreement, Stockholder agrees with, and
                  covenants to, Parent as follows:

         3.1      Transfer. Stockholder shall not (i) transfer (which term shall
                  include,   without  limitation,   for  the  purposes  of  this
                  Agreement, any sale, gift, pledge, assignment,  encumbrance or
                  other  disposition)  or consent to any transfer of, any or all
                  of the Shares or any interest therein,  except pursuant to the
                  Merger,  or (ii)  enter  into any  contract,  option  or other
                  agreement or understanding with respect to any transfer of any
                  or all such Shares or any  interest  therein or take any other
                  action with respect thereto,  in either case, in a manner that
                  would  conflict  with or violate  the terms of the  "affiliate
                  letter" executed by Stockholder pursuant to Section 4 hereof.

         3.2      Solicitation.  Prior to the Effective Time, Stockholder agrees
                  that it shall not directly or  indirectly  (including  through
                  representatives,     advisors,    agents    or    any    other
                  intermediaries),  (i) solicit or initiate (including by way of
                  furnishing or disclosing non-public information) any inquiries
                  or the making of any  proposal  with  respect  to any  merger,
                  consolidation  or other  business  combination  involving  the
                  Company or any Subsidiary (as defined in the Merger Agreement)
                  of the Company or the  acquisition  of all or any  significant
                  part of the assets or capital stock of the Company,  including
                  the Shares,  or any Subsidiary of the Company (an "Acquisition
                  Transaction")   or  (ii)  negotiate  or  otherwise  engage  in
                  discussions  with  any  person  (other  than  Parent  and  its
                  representatives) with respect to any Acquisition  Transaction,
                  or which may  reasonably be expected to lead to a proposal for
                  an  Acquisition  Transaction  or  enter  into  any  agreement,
                  arrangement  or   understanding   with  respect  to  any  such
                  Acquisition  Transaction or which would require the Company to
                  abandon, terminate or fail to consummate the Merger or require
                  Stockholder  to  abandon,  terminate  or fail to  perform  its
                  obligations under this Agreement.

         3.3      Notifications.  Stockholder  shall, while this Agreement is in
                  effect, notify Parent promptly, but in no event later than two
                  business  days, of the number of any shares of Company  Common
                  Stock acquired by Stockholder after the date hereof.

         4.       Delivery of Affiliate  Letter.  Stockholder  shall execute and
                  deliver to Parent an  "affiliate  letter" in the form attached
                  as an exhibit to the Merger  Agreement as  contemplated by the
                  Merger Agreement.

         5. Effect of  Purported  Transfer.  The parties  hereto  agree that any
transfer of the Shares made other than in compliance  with this Agreement  shall
be null and void.  Any such  transfer  shall  convey no  interest  in any of the
Shares purported to be transferred, and the transferee shall not be deemed to be
a stockholder of the Company nor entitled to receive a new share  certificate or
any rights,  dividends or other distributions on or with respect to such Shares.
The Company is a party to this Agreement solely for the purpose of acknowledging
the approval of this  Agreement  by its Board of Directors  and to agree that it
will not permit to be  registered  any transfer of the Shares made other than in
compliance with this Agreement.

         6.  Termination.  This Agreement  shall terminate on the earlier of (i)
the  Effective  Time (as defined in the Merger  Agreement)  or (ii)  immediately
after the termination of the Merger Agreement in accordance with its terms.

         7. Action in Stockholder Capacity Only.  Stockholder makes no agreement
or understanding  herein as director or officer of the Company.  The Stockholder
signs solely in its capacity as a recordholder  and beneficial  owner of, or the
general partner of the partnership which is the beneficial owner of, the Shares,
and nothing herein shall limit or affect any actions taken in its capacity as an
officer or director of the Company.

         8.       Miscellaneous.

         8.1      Notices.  All  notices,  requests,  claims,  demands and other
                  communications  under this  Agreement  shall be in writing and

                  notices of a change of address  shall be  effective  only upon
                  receipt  thereof).  Any such notice  shall be  effective  upon

         8.2      Entire Agreement. This Agreement,  together with the documents
                  expressly referred to herein,  constitute the entire agreement
                  and supersede all other prior  agreements and  understandings,

                  hereto.

         8.4      Assignment.  This Agreement shall be binding upon and inure to

         8.5      Governing  Law.  This  Agreement,  and  all  matters  relating
                  hereto, shall be governed by, and construed in accordance with

         8.6      Injunctive Relief;  Jurisdiction.  Stockholder and the Company
                  agree that  irreparable  damage  would  occur and that  Parent
                  would not have any  adequate  remedy at law in the event  that

                  accordance   with  their  specific  terms  or  were  otherwise
                  breached.  It is  accordingly  agreed  that  Parent  shall  be
                  entitled to an injunction or injunctions  to prevent  breaches
                  by Stockholder or the Company of this Agreement and to enforce
                  specifically the terms and provisions of this Agreement in any
                  court of the United States located in the State of Delaware or
                  in any Delaware state court (collectively, the "Courts"), this
                  being in  addition  to any  other  remedy  to  which  they are
                  entitled at law or in equity. In addition, each of the parties
                  hereto (i)  irrevocably  consents  to the  submission  of such
                  party to the personal  jurisdiction of the Courts in the event
                  that any dispute  arises out of this  Agreement  or any of the
                  transactions  contemplated hereby, (ii) agrees that such party
                  will not attempt to deny or defeat such party to the  personal
                  jurisdiction  by motion or other request for leave from any of
                  the Courts and (iii) agrees that such party will not bring any
                  action  relating to this Agreement or any of the  transactions
                  contemplated hereby in any court other the Courts. Stockholder
                  hereby  appoints,   and  shall  give  prompt  notice  of  such
                  appointment to, the Prentice-Hall  Corporation System, Inc. as
                  its  authorized  agent  (the  "Authorized  Agent")  upon which
                  process  may be served in any action  based on this  Agreement
                  which  may  be  instituted  in  the  Courts  by  Parent,   and
                  Stockholder and the Company expressly accepts the jurisdiction
                  of any such Court in respect to such action.  Such appointment
                  shall be irrevocable. Stockholder represents and warrants that
                  the  Authorized  Agent  has  agreed  to act as said  agent for
                  service of process, and Stockholder agrees to take any and all
                  action, including,  without limitation,  the filing of any and
                  all  documents  and  instruments,  which may be  necessary  to
                  continue such appointment in full force and effect. Service of
                  process upon the  Authorized  Agent and written notice of such
                  service  to  Stockholder  shall be deemed,  in every  respect,
                  effective service of process upon Stockholder.

         8.7      Counterparts.  This Agreement may be executed in any number of
                  counterparts,  each of which shall be deemed to be an original
                  and all of which  together  shall  constitute one and the same
                  document.

         8.8      Severability. Any term or provision of this Agreement which is
                  invalid or unenforceable in any jurisdiction shall, as to such
                  jurisdiction,  be ineffective to the extent of such invalidity
                  or unenforceability without rendering invalid or unenforceable
                  the  remaining  terms  and  provisions  of this  Agreement  or
                  affecting the validity or  enforceability  of any of the terms
                  or provisions of this Agreement in any other jurisdiction.  If
                  any  provision  of  this  Agreement  is  so  broad  as  to  be
                  unenforceable,  such provision shall be interpreted to be only
                  so broad as is enforceable.

                  contrary,  (i) Stockholder  shall not be responsible  for, and
                  its rights hereunder shall not be affected by, the performance
                  or nonperformance by the Company of its obligations  hereunder
                  and (ii) the Company  shall not be  responsible  for,  and the
                  Company's  rights  hereunder  shall not be  affected  by,  the
                  performance  or  nonperformance  by  the  Stockholder  of  its
                  obligations hereunder.
