                           KNOW-HOW LICENSE AGREEMENT

         This Agreement is made effective as of February 26, 1998 ("Effective
Date"), between Micron Electronics, Inc. ("MEI"), a corporation having an office
at 900 East Karcher Road, Nampa, Idaho 83687, and MCMS, Inc. (f/k/a Micron
Custom Manufacturing Services, Inc.) ("MCMS"), a corporation having a place of
business at 16399 Franklin Road, Nampa, Idaho 83687.

         Whereas, this Agreement is made pursuant to, and is attached as a
Exhibit to, that Recapitalization Agreement dated December 21, 1997 by and among
MCMS, MEI, and Cornerstone Equity Investors, IV, L.P.;

         Whereas MEI is the owner of certain Know-How, as defined below; and

         Whereas MCMS desires to acquire a license to the Know-How; and

         Whereas MEI is willing to grant a non-exclusive license to the Know-How
to MCMS for good and valuable consideration, the adequacy and receipt of which
is hereby acknowledged, and on the terms and conditions set forth in this
Agreement;

         Now, therefore, MEI and MCMS hereby agree to the following:

1.       Definitions

         1.2.     "Subsidiary" shall mean a corporation, company, or other legal
                  entity (i) more than fifty percent (50%) of whose outstanding
                  shares or securities (representing the right to vote for the
                  election of directors or other managing authority) are, now or
                  hereafter, owned or controlled, directly or indirectly, by
                  MCMS; or (ii) which does not have outstanding shares or
                  securities, but more than fifty percent (50%) of whose
                  ownership interest representing the right to make the
                  decisions for such corporation, company, or other entity is,
                  now or hereafter, owned or controlled, directly or indirectly,
                  by MCMS.

         1.3.     "Know-How" shall mean: scientific and engineering information,
                  trade secrets, specifications, manufacturing and production
                  processes and techniques, research and development
                  information, designs, plans, proposals, technical data and
                  other technical know-how that was conceived by MCMS prior to
                  the Effective Date or utilized by MCMS as of the Effective
                  Date and that relates to the Business, provided, however, that
                  Know-How shall not include any MEI patents, patent
                  applications, or any invention disclosures (or the inventions
                  disclosed within the aforementioned patents, patent
                  applications, or invention disclosures) not

                  otherwise assigned to MCMS in the PATENT AND INVENTION
                  DISCLOSURE ASSIGNMENT AND LICENSE AGREEMENT executed on the
                  Effective Date.

         1.4.     "Business" shall mean the design, assembly, or testing of
                  custom complex printed circuit boards, memory intensive
                  products and system level assemblies for third party
                  electronics original equipment manufacturers.

2.       Warranties

         2.1.     MEI warrants that it has not previously granted any assignment
                  or exclusive license in or to the Know-How to any third party,
                  and that MEI has the full right and capacity to license the
                  Know-How to MCMS, and to enter into and carry out its
                  obligations under this Agreement, without conflicting with any
                  other obligation of MEI.

3.       Know-How License

         3.1.     MEI hereby grants to MCMS an irrevocable (except as set forth
                  in Section 3.3), non-transferable, fully paid up, worldwide,
                  non-exclusive license to utilize the Know-How solely in
                  connection with the Business. MCMS shall have no right to
                  sublicense its rights granted hereunder to any third party
                  without the prior written consent of MEI, which consent shall
                  not be unreasonably withheld, provided, however, that MEI's
                  refusal to consent to MCMS' grant of a sublicense to an MEI
                  competitor shall not be deemed to be unreasonable.

         3.2.     MCMS shall not assign or transfer any of its rights granted
                  hereunder without the prior written consent of MEI.
                  Notwithstanding the foregoing, an assignment or transfer of
                  the Agreement and the licenses granted therein may be effected
                  by operation of law, such as for example, by merger,
                  consolidation, sale of the business or assets,
                  reincorporation, or nonbankruptcy reorganization.

         3.3.     This Agreement shall commence on the Effective Date and shall
                  continue thereafter in perpetuity; provided, however, that
                  either party may, upon ninety (90) days written notice to the
                  other party, terminate this Agreement in the event of a
                  material breach thereof by such party; provided, further, that
                  if such breach is cured within such ninety (90) day period,
                  this Agreement shall not be so terminated.

4.       Miscellaneous

         4.1.     Except as set forth in the Recapitalization Agreement, MEI
                  neither warrants nor represents that the use of the Know-How
                  will not result in infringement of any patents of any third
                  party.

         4.2.     No modification of or amendment to this Agreement shall be
                  valid unless in a writing signed by the parties hereto
                  referring specifically to this Agreement and stating the
                  parties' intention to modify or amend the same. Any waiver of
                  any term or condition of this Agreement must be in a writing
                  signed by the party hereto sought to be charged with such
                  waiver referring specifically to the term or condition to be
                  waived, and no such waiver shall be deemed to constitute the
                  waiver of any other breach of the same or of any other term or
                  condition of this Agreement.

         4.3.     For a period of ten (10) years from the Effective Date, MCMS
                  and its sublicensees shall hold and keep as confidential and
                  secret all Know-How. During such ten (10) year period, MCMS
                  and its sublicensees shall take reasonable precautions to
                  prevent unauthorized disclosure and to safeguard the
                  confidentiality and secrecy of the Know-How, provided,
                  however, that MCMS and its sublicensees shall have the right
                  to disclose such Know-How to third parties to whom disclosure
                  is made in the ordinary course of the Business under
                  reasonable obligations of confidentiality.

                  MCMS and its sublicensees shall not be required to keep secret
                  and confidential any Know-How which they can demonstrate:

                  (i)      has become generally available to the public through
                           no fault, negligence, unauthorized act or omission of
                           MCMS or its sublicensees and not as a result of a
                           breach of this Agreement; or

                  (ii)     is lawfully disclosed to MCMS or its sublicensees by
                           an independent third party not previously employed by
                           MCMS or its sublicensees and that lawfully acquired
                           such information through no breach of any direct or
                           indirect obligation to MEI.

         4.4      All notices and other communications hereunder shall be
                  sufficiently given for all purposes hereunder if in writing
                  and delivered personally, sent by documented overnight
                  delivery service or, to the extent receipt is confirmed,
                  telecopy, telefax or other electronic transmission service to
                  the appropriate address or number as set forth below or to
                  such other address or to the attention of such other person as
                  one party may designate by written notice to the other party
                  hereto.

         4.5      The headings and captions contained in this Agreement are for
                  reference purposes only and shall not affect in any way the
                  meaning or interpretation of this Agreement. The use of the
                  word "including" herein shall mean "including without
                  limitation."

         4.6      The language used in this Agreement shall be deemed to be the
                  language chosen by the parties hereto to express their mutual
                  intent, and no rule of strict construction shall be applied
                  against any person.

         4.7      This Agreement and the Recapitalization Agreement contain the
