                  THIS AMENDED AND RESTATED WAFER FABRICATION AGREEMENT (the
"AGREEMENT"), is entered into as of this 21st day of April, 1999 (to be
effective as of the Closing Date, as defined below), by and between ADVANCED
MICRO DEVICES, INC., a Delaware corporation having its principal place of
business at One AMD Place, Sunnyvale, California 94086 ("AMD"), and Vantis
Corporation, a Delaware corporation having its principal place of business at
995 Stewart Drive, Sunnyvale, California 94088 ("VANTIS").

1.       BACKGROUND

         1.1. AMD. AMD is in the business of designing, manufacturing,
testing and selling semiconductor devices, among other products. AMD
manufactures certain semiconductor devices along submicron process lines
within AMD's plant located at 5204 East Ben White Boulevard, Austin, Texas
78741 ("[*]" and "[*]") and within AMD's Submicron Development Center located
at 915 DeGuigne Drive, Sunnyvale, CA 94088 (the "[*]") [*] are collectively
referred to herein as the "FACILITIES").

         1.2. VANTIS. Vantis is in the business of designing, developing and
marketing CMOS programmable logic devices, field programmable gate arrays and
related software.

         1.3. SCOPE OF AGREEMENT. AMD has historically fabricated semiconductor
devices for AMD's programmable logic business (the "BUSINESS") at the
Facilities. AMD has transferred the Business to Vantis. AMD has entered into an
agreement with Lattice Semiconductor Corporation ("LATTICE") pursuant to which
Lattice has agreed to purchase, and AMD has agreed to sell, the stock of Vantis
to Lattice (the "PURCHASE AGREEMENT," such transaction the "PURCHASE"). After
the Purchase, the parties desire to continue a fabrication relationship between
the Business and AMD. Specifically, Vantis desires to develop and sell
programmable logic semiconductor devices and AMD desires to fabricate such
semiconductor devices (the "WAFERS") at the Facilities.

         1.4 PURPOSE OF AMENDED AGREEMENT. In connection with the Purchase, AMD
and Vantis have agreed to amend and restate, in this Agreement, the Wafer
Fabrication Agreement between them dated as of September 27, 1997, as amended,
to be effective as of the Closing Date (as defined in the Purchase Agreement),
so as to assure that during the term of this Agreement AMD will continue to
provide to Vantis, for the benefit of Lattice, wafer fabrication services
following the Closing (as defined in the Purchase Agreement).

                                    AGREEMENT

             NOW, THEREFORE, in consideration of the premises and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties agree as follows:

                   (a) During the portion of the Term up to and including [*]:
The Long-Term Committed Capacity Amount for each year in any Communication
responding to a Annual Forecast shall not be less than the lower of (i) the
Maximum Committed Capacity Amount applicable to such year or (ii) the Long-Term
Committed Capacity Amount for such year specified by AMD in the Communication
responding to the immediately preceding Annual Forecast (the "PRIOR LONG-TERM
COMMITTED CAPACITY AMOUNT"); PROVIDED, HOWEVER, that if the forecasted die
demand amount for such year (the "FORECASTED ANNUAL AMOUNT") is less than the
lower of (I) the Maximum Committed Capacity Amount applicable to such year or
(II) the Prior Long-Term Committed Capacity Amount for such year, the Long-Term
Committed Capacity Amount for such year may be lower than the Maximum Committed
Capacity Amount applicable to such year or Prior Long-Term Committed Capacity
Amount, but in any event shall not be less than the Forecasted Annual Amount.

                   (b) During the portion of the Term up to and including [*]:
The Short-Term Committed Capacity Amount for each [*] in any Communication
responding to a Rolling [*] Forecast shall not be less than the lower of (i) the
Long-Term Committed Capacity Amount specified for such [*] in the Communication
responding to the Annual Forecast immediately preceding such Rolling [*]
Forecast (the "BASE AMOUNT") or (ii) the Short-Term Committed Capacity Amount
for such [*] specified by AMD in the Communication responding to the immediately
preceding Rolling [*] Forecast (the "PRIOR SHORT-TERM COMMITTED CAPACITY
AMOUNT"); PROVIDED, HOWEVER, that if the forecasted die demand amount for such
[*] (the "FORECASTED AMOUNT") is less than the lower of (I) the Base Amount for
such [*] or (II) the Prior Short-Term Committed Capacity Amount for such [*],
the Short-Term Committed Capacity Amount for such [*] may be lower than the Base
Amount or Prior Short-Term Committed Capacity Amount but in any event shall not
be less than the appropriate percentage of the [*] Minimum for such [*]
determined in accordance with Exhibit B.

                   (c) During the portion of the Term from and after [*]: The
Short-Term Committed Capacity Amount for each [*] in any Communication
responding to a Rolling [*] Forecast shall not be less than (i) the lower of the
appropriate percentage of the [*] Minimum for such [*] determined in accordance
with Exhibit B or (ii) the Prior Short-Term Committed Capacity Amount.

              9.2.3 WAIVER OF PRIOR COMMITTED CAPACITY AMOUNTS.

                   (a) In the event that, in accordance with Article 9.2.2(a),
the Long-Term Committed Capacity Amount for a [*] specified by Vantis is less
than the Prior Long-Term Committed Capacity Amount for such year, AMD shall have
the right to waive the Prior Long-Term Committed Capacity Amount for such year
for purposes of calculating the Minimum Annual Purchased Capacity Amount of
Wafers applicable to such year. Any such waiver shall be contained in writing in
the Communication specifying the new Long-Term Committed Capacity Amount for
such year.

                   (b) In the event that, in accordance with Article 9.2.2 (b)
or (c), the Short-Term Committed Capacity Amount for a [*] specified by Vantis
is less than the Prior Short-Term Committed Capacity Amount for such [*], AMD
shall have the right to waive the Prior Short-Term Committed Capacity Amount for
such [*] for purposes of calculating the [*] Minimum Quarterly Purchased
Capacity Amount of Wafers applicable to such [*]. Any such waiver shall be
contained in writing in the Communication specifying the new Short-Term
Committed Capacity Amount for such [*].

              9.2.4 DISPOSITION OF EXCESS WAFER CAPACITY. If, after Vantis
delivers the latest Rolling [*] Forecast, a [*] Minimum applicable to any [*] is
lower than the [*] Minimum previously applicable to such [*], but AMD does not
waive the [*] Minimum for such [*] for purposes of calculating the Minimum [*]
Purchased Capacity Amount of Wafers applicable to such [*], AMD shall use
Commercially Reasonably Efforts to use, or cause to be used, the amount of
production capacity that AMD would need to maintain to fabricate a quantity of
Wafers equivalent to the difference between the [*] Minimum previously
applicable to such [*] and the latest [*] Minimum.

         9.3. COMMITTED BUILD AMOUNT; MAXIMUM COMMITTED BUILD AMOUNT. AMD shall
set forth in each Communication responding to a Rolling [*] Forecast an amount
of Wafers equal to [*] of the [*] Minimum for the next [*] that AMD shall
fabricate (the "COMMITTED BUILD AMOUNT"). AMD shall not be under any obligation
to set forth in any Communication a Committed Build Amount for the next [*] in
excess of a Short-Term Committed Capacity Amount for such [*] specified in a
Communication responding to a prior Rolling [*] Forecast.

         9.4. COOPERATION CLAUSE. If and when requested by AMD, Vantis shall use
Commercially Reasonable Efforts to submit its Die and/or Wafer demand needs to
AMD in a format which is compatible with AMD's Total Order Management ("TOM")

be referred to more senior executives of each party who have authority to settle
the dispute and who shall likewise meet (in person or by telephone) to attempt
to resolve the dispute. Within five business days after the referral of the
dispute to more senior executives of each party, the senior executives of both
parties shall meet at a mutually acceptable time and place (including telephonic
conference), and thereafter as often as they reasonably deem necessary, to
attempt to resolve the dispute.

              14.2.3 If the matter has not been resolved within ten days from
the referral of the dispute to such senior executives, then the parties may
pursue litigation or, if mutually agreed, alternative dispute resolution
mechanisms.

         14.3. NO CONSEQUENTIAL DAMAGES. IN NO EVENT SHALL EITHER PARTY BE
LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, SPECIAL, CONSEQUENTIAL OR INCIDENTAL
DAMAGES (INCLUDING LOST PROFITS) WHETHER BASED ON WARRANTY, CONTRACT, TORT OR
ANY OTHER LEGAL THEORY REGARDLESS OF WHETHER SUCH PARTY HAD ACTUAL OR
CONSTRUCTIVE NOTICE OF SUCH DAMAGES.

         14.4. INJUNCTION. Either party may seek a preliminary injunction or
other preliminary judicial relief if, in its judgment, such action is necessary
to avoid irreparable damage.

         14.5. ASSIGNMENT. Without the prior written consent of the other party,
which consent may not be unreasonably withheld, neither party, either
voluntarily or by operation of law, shall assign, transfer or otherwise dispose

compliance with the provisions of this Article 14.5, the provisions of this
Agreement shall be binding upon and inure to the benefit of the parties and
their respective successors, assigns and Transferees.

Lattice may disclose the existence and the terms of this Agreement (i) in a
registration statement or other document filed by either party or Lattice with
the Securities and Exchange Commission, (ii) in accordance with generally
accepted accounting procedures if required under the rules of the Securities and
Exchange Commission or National Association of Securities Dealers Automated

subsequent action. A waiver of any right accruing to either party pursuant to
this Agreement shall not be effective unless given in writing.
