     1.   NUMBER OF WARRANT SHARES; DURATION AND EXERCISE OF WARRANT;
          DETERMINATION OF EXERCISE PRICE; PAYMENT OF TAXES.

     1.1  NUMBER OF WARRANT SHARES.

     This Warrant shall enable the Warrantholder to purchase two million
(2,000,000) shares of Common Stock, subject to the provisions of Section 6
hereof.

     1.2  DURATION AND EXERCISE OF WARRANT.

     (a)  Cash Exercise. This Warrant may be exercised by the Warrantholder by
(i) the surrender of this Warrant to the Company, with a duly executed Exercise
Form specifying the number of Warrant Shares to be purchased (which number shall
be no fewer than 100,000 shares), during normal business hours on any Business
Day during the Exercise Period and (ii) the delivery of payment to the Company,
for the account of the Company, by wire transfer of immediately available funds
to a bank account specified by the Company, of the Exercise Price for the number
of Warrant Shares specified in the Exercise Form in lawful money of the United
States of America. The Company agrees that such Warrant Shares shall be deemed
to be issued to the Warrantholder as the record holder of such Warrant Shares as
of the close of business on the date on which this Warrant shall have been
surrendered and payment made for the Warrant Shares as aforesaid. A stock
certificate or certificates for the Warrant Shares specified in the Exercise
Form shall be delivered to the Warrantholder as promptly as practicable, and in
any event within 10 days, thereafter. The stock certificate or certificates so
delivered shall be in denominations of 100 shares each or such lesser or greater
denominations as may be reasonably specified by the Warrantholder in the
Exercise Form. If this Warrant shall have been exercised only in part, the
Company shall, at the time of delivery of the stock certificate or certificates,
deliver to the Warrantholder a new Warrant evidencing the rights to purchase the
remaining Warrant Shares, which new Warrant shall in all other respects be
identical with this Warrant. No adjustments shall be made on Warrant Shares
issuable on the exercise of this Warrant for any cash dividends paid or payable
to holders of record of Common Stock prior to the date as of which the
Warrantholder shall be deemed to be the record holder of such Warrant Shares.

     (b)  Net Issue Exercise. In lieu of exercising this Warrant pursuant to
Section 1.2(a) hereof, this Warrant may be exercised by the Warrantholder by the
surrender of this Warrant to the Company, with a duly executed Exercise Form
marked to reflect Net Issue Exercise and specifying the number of Warrant Shares
to be purchased, during normal business hours on any Business Day during the
Exercise Period. The Company agrees that such Warrant Shares shall be deemed to
be issued to the Warrantholder as the record holder of such Warrant Shares as of
the close of business on the date on which this Warrant shall have been
surrendered as aforesaid. Upon such exercise, the Warrantholder shall be
entitled to receive shares equal to the value of this Warrant (or the portion
hereof being exercised) computed as of the date of surrender of this Warrant to
the Company using the following formula:

        X = Y x (A-B)
            ---------
                A


                                      -2-
<PAGE>   3

Where X = the number of shares of Common Stock to be issued to Warrantholder
          under this Section 1.2(b);

      Y = the number of shares of Common Stock otherwise purchasable under
          this Warrant (at the date of such calculation), which number shall not
          be less than 100,000;

      A = the fair market value of one share of Common Stock (at the date of
          such calculation);

      B = the Exercise Price.

     (c)  Fair Market Value. For purposes of Sections 1.2(b) and 6.1(d), "fair
market value" of one share of Common Stock shall mean:

          (i)  the average closing price per share of the Common Stock on the
     principal national securities exchange on which the Common Stock is listed
     or admitted to trading for the ten (10) Trading Day period ending three (3)
     Trading Days prior to the date of exercise or,

          (ii) if not listed or traded on any such exchange, the average last
     reported sale price per share of the Common Stock on the Nasdaq National
     Market or The Nasdaq SmallCap Market (collectively, "Nasdaq") for the ten
     (10) Trading Day period ending three (3) Trading Days prior to the date of
     exercise, or

          (iii) if not listed or traded on any such exchange or Nasdaq, the
     average of the mean of the bid and asked prices per share of the Common
     Stock as reported in the OTC Bulletin Board or, if not so reported, in the
     "pink sheets" published by the National Quotation Bureau, Inc. for the ten
     (10) Trading Day period ending three (3) Trading Days prior to the date of
     exercise, or

          (iv) if such quotations are not available, the fair market value per
     share of the Common Stock as of the date in question as reasonably
     determined by the Board of Directors of the Company.

     1.3  EXERCISE PRICE. The Exercise Price shall be $10.00 per share of Common
Stock, subject to the provisions of Section 6 hereof.

     1.4  PAYMENT OF TAXES. The issuance of certificates for Warrant Shares
shall be made without charge to the Warrantholder for any stock transfer or
other issuance tax in respect thereto; provided, however, that the Warrantholder
shall be required to pay any and all taxes which may be payable in respect of
any transfer involved in the issuance and delivery of any certificate in a name
other than that of the then Warrantholder as reflected upon the books of the
Company.

     1.5  EARLY TERMINATION. Notwithstanding anything herein to the contrary,
this warrant shall immediately cease to be exercisable and all rights of the
Warrantholder hereunder shall immediately terminate upon a material breach by
Warrantholder or JV of Amended and


                                      -3-

Restated Investment Agreement, dated as of August 28, 2000, by and between the
Company, VIA Technologies, Inc. and JV, including, without limitation, Section
5.13 thereof.

     2.   RESTRICTIONS ON TRANSFER; RESTRICTIVE LEGENDS.

     2.1  RESTRICTIONS ON TRANSFER; COMPLIANCE WITH SECURITIES LAWS. This
Warrant and the Warrant Shares issued upon the exercise of the Warrant may not
be transferred or assigned in whole or in part without compliance with all
applicable federal and state securities laws by the transferor and transferee
(including the delivery of investment representation letters and legal opinions
reasonably satisfactory to the Company, if such are requested by the Company).
The Warrantholder, by acceptance hereof, acknowledges that this Warrant and the
Warrant Shares to be issued upon exercise hereof are being acquired solely for
the Warrantholder's own account and not as a nominee for any other party, and
for investment, and that the Warrantholder will not offer, sell or otherwise
dispose of any Warrant Shares to be issued upon exercise hereof except under
circumstances that will not result in a violation of the Securities Act or any
state securities laws. Upon exercise of this Warrant, the Warrantholder shall,
if requested by the Company, confirm in writing, in a form satisfactory to the
Company, that the Warrant Shares so purchased are being acquired solely for the
Warrantholder's own account and not as a nominee for any other party, for
investment, and not with a view toward distribution or resale.

     2.2  RESTRICTIVE LEGENDS. This Warrant shall (and each Warrant issued upon
transfer in whole or in part of this Warrant pursuant to this Section 2 or
issued in substitution for this Warrant issued pursuant to Section 4 shall) be
stamped or otherwise imprinted with a legend in substantially the following
form:

          "THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS
     WARRANT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED (THE "SECURITIES ACT"), OR APPLICABLE STATE SECURITIES LAWS AND
     HAVE BEEN ISSUED PURSUANT TO AN EXEMPTION THEREFROM. EXCEPT AS PERMITTED
     UNDER APPLICABLE FEDERAL AND STATE SECURITIES LAWS, THE WARRANT AND ANY
     SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT MAY NOT BE SOLD OR
     OTHERWISE TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
     UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, OR AN
     OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION IS NOT
     REQUIRED."

Except as otherwise permitted by this Section 2, each stock certificate for
Warrant Shares issued upon the exercise of any Warrant and each stock
certificate issued upon the direct or indirect transfer of any such Warrant
Shares shall be stamped or otherwise imprinted with a legend in substantially
the following form:

          "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
     APPLICABLE STATE SECURITIES LAWS, AND HAVE BEEN ISSUED PURSUANT TO AN


                                      -4-
<PAGE>   5

     EXEMPTION THEREFROM. EXCEPT AS PERMITTED UNDER APPLICABLE FEDERAL AND STATE
     SECURITIES LAWS, THE SHARES MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR
     OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION UNDER THE
     SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF
     COUNSEL ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED."

     Notwithstanding the foregoing, the Warrantholder may require the Company to
issue a stock certificate for Warrant Shares without a legend if (i) such
Warrant Shares, as the case may be, have been registered for resale under the
Securities Act or sold pursuant to Rule 144 under the Securities Act (or a
successor rule thereto) or (ii) the Warrantholder has received an opinion of
counsel reasonably satisfactory to the Company that such registration is not
required with respect to such Warrant Shares.

     3.   RESERVATION AND REGISTRATION OF SHARES, ETC.

     The Company covenants and agrees that all Warrant Shares which are issuable
upon the exercise of this Warrant will, upon issuance, be validly issued, fully
paid and nonassessable and free from all taxes, liens, security interests,
charges and other encumbrances with respect to the issue thereof, other than
taxes in respect of any transfer occurring contemporaneously with such issue.
The Company further covenants and agrees that, during the Exercise Period, the
Company will at all times have authorized and reserved, and keep available free
from preemptive rights, a sufficient number of shares of Common Stock to provide
for the exercise of the rights represented by this Warrant and will, at its
expense, upon each such reservation of shares, procure such listing of such
shares of Common Stock (subject to issuance or notice of issuance) as then may
be required on all stock exchanges on which the Common Stock is then listed or
on Nasdaq.

     4.   EXCHANGE, LOSS OR DESTRUCTION OF WARRANT.

     Upon receipt by the Company of evidence satisfactory to it of the loss,
theft, destruction or mutilation of this Warrant and, in the case of loss, theft
or destruction, of such bond or indemnification as the Company may require, and,
in the case of such mutilation, upon surrender and cancellation of this Warrant,
the Company will execute and deliver a new Warrant of like tenor. The term
"Warrant" as used in this Agreement shall be deemed to include any Warrants
issued in substitution or exchange for this Warrant.

     5.   OWNERSHIP OF WARRANT.

     The Company may deem and treat the person in whose name this Warrant is
registered as the holder and owner hereof (notwithstanding any notations of
ownership or writing hereon made by anyone other than the Company) for all
purposes and shall not be affected by any notice to the contrary.

     6.   CERTAIN ADJUSTMENTS.

     6.1  The number of Warrant Shares purchasable upon the exercise of this
Warrant and the Exercise Price shall be subject to adjustment as follows:

          (a)  Stock Dividends. If at any time prior to the exercise of this
Warrant in full (i) the Company shall fix a record date for the issuance of any
stock dividend payable in shares of Common Stock or (ii) the number of shares of
Common Stock shall have been increased by a subdivision or split-up of shares of
Common Stock, then, on the record date fixed for the determination of holders of
Common Stock entitled to receive such dividend or immediately after the
effective date of subdivision or split-up, as the case may be, the number of
shares of Common Stock to be delivered upon exercise of this Warrant will
increased so that the Warrantholder will be entitled to receive the number of
shares of Common Stock that such Warrantholder would have owned immediately
following such action had this Warrant been exercised immediately prior thereto,
and the Exercise Price will be adjusted as provided below in paragraph (f).

          (b)  Combination of Stock. If at any time prior to the exercise of
this Warrant in full the number of shares of Common Stock outstanding shall have
been decreased by a combination of the outstanding shares of Common Stock, then,
immediately after the effective date of such combination, the number of shares
of Common Stock to be delivered upon exercise of this Warrant will be decreased
so that the Warrantholder thereafter will be entitled to receive the number of
shares of Common Stock that such Warrantholder would have owned immediately
following such action had this Warrant been exercised immediately prior thereto,
and the Exercise Price will be adjusted as provided below in paragraph (f).

          (c)  Reorganization, etc. If at any time prior to the exercise of this
Warrant in full any capital reorganization of the Company, or any
reclassification of the Common Stock, or any consolidation of the Company with
or merger of the Company with or into any other person or any sale, lease or
other transfer of all or substantially all of the assets of the Company to any
other person, shall be effected in such a way that the holders of Common Stock
shall be entitled to receive stock, other securities or assets (whether such
stock, other securities or assets are issued or distributed by the Company or
another person) with respect to or in exchange for Common Stock, then, upon
exercise of this Warrant the Warrantholder shall have the right to receive the
kind and amount of stock, other securities or assets receivable upon such
reorganization, reclassification, consolidation, merger or sale, lease or other
transfer by a holder of the number of shares of Common Stock that such
Warrantholder would have been entitled to receive upon exercise of this Warrant
had this Warrant been exercised immediately before such reorganization,
reclassification, consolidation, merger or sale, lease or other transfer,
subject to adjustments that shall be as nearly equivalent as may be practicable
to the adjustments provided for in this Section 6.

          (d)  Fractional Shares. No fractional shares of Common Stock or scrip
shall be issued to any Warrantholder in connection with the exercise of this
Warrant. Instead of any fractional shares of Common Stock that would otherwise
be issuable to such Warrantholder, the Company will pay to such Warrantholder a
cash adjustment in respect of such fractional interest in an


                                      -6-
<PAGE>   7


amount equal to that fractional interest of the fair market value of one share
of Common Stock as of the date of exercise.

     (e)  Carryover. Notwithstanding any other provision of this Section 6, no
adjustment shall be made to the number of shares of Common Stock to be delivered
to the Warrantholder (or to the Exercise Price) if such adjustment represents
less than 1% of the number of shares to be so delivered, but any lesser
adjustment shall be carried forward and shall be made at the time and together
with the next subsequent adjustment which together with any adjustments so
carried forward shall amount to 1% or more of the number of shares to be so
delivered.

     (f)  Exercise Price Adjustment. Whenever the number of Warrant Shares
purchasable upon the exercise of the Warrant is adjusted, as herein provided,
the Exercise Price payable upon the exercise of this Warrant shall be adjusted
by multiplying such Exercise Price immediately prior to such adjustment by a
fraction, of which the numerator shall be the number of Warrant Shares
purchasable upon the exercise of the Warrant immediately prior to such
adjustment, and of which the denominator shall be the number of Warrant Shares
purchasable immediately thereafter.

     (g)  No Duplicate Adjustments. Notwithstanding anything else to the
contrary contained herein, in no event will an adjustment be made under the
provisions of this Section 6 to the number of Warrant Shares issuable upon
exercise of this Warrant or the Exercise Price for any event if an adjustment
having substantially the same effect to the Warrantholder as any adjustment that
otherwise would be made under the provisions of this Section 6 is made by the
Company for any such event to the number of shares of Common Stock (or other
securities) issuable upon exercise of this Warrant.

     6.2  NO ADJUSTMENT FOR DIVIDENDS. Except as provided in Section 6.1, no
adjustment in respect of any dividends shall be made during the term of the
Warrant or upon the exercise of this Warrant.

     6.3  NOTICE OF ADJUSTMENT. Whenever the number of Warrant Shares or the
Exercise Price of such Warrant Shares is adjusted, as herein provided, the
Company shall promptly mail by first class, postage prepaid, to the
Warrantholder, notice of such adjustment or adjustments and a certificate of the
chief financial officer of the Company setting forth the number of Warrant
Shares and the Exercise Price of such Warrant Shares after such adjustment,
setting forth a brief statement of the facts requiring such adjustment and
setting forth the computation by which such adjustment was made.

     7.   NOTICES OF CORPORATE ACTION.

     In the event of

     (a)  any taking by the Company of a record of the holders of any class of
securities for the purpose of determining the holders thereof who are entitled
to receive any dividend or other distribution, or any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, or


                                       -7-
<PAGE>   8

     (b)  any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company or any Change of Control,
or

     (c)  any voluntary or involuntary dissolution, liquidation or winding-up of
the Company,

the Company will mail to the Warrantholder a notice specifying (i) the date or
expected date on which any such record is to be taken for the purpose of such
dividend, distribution or right and the amount and character of any such
dividend, distribution or right, (ii) the date or expected date on which any
such reorganization, reclassification, recapitalization, Change of Control,
dissolution, liquidation or winding-up is to take place and the time, if any
such time is to be fixed, as of which the holders of record of Common Stock (or
other securities) shall be entitled to exchange their shares of Common Stock (or
other securities) for the securities or other property deliverable upon such
reorganization, reclassification, recapitalization, Change of Control,
dissolution, liquidation or winding-up and (iii) that in the event of a Change
of Control, the Warrants are exercisable immediately prior to the consummation
of such Change of Control. Such notice shall be mailed at least 20 days prior to
the date therein specified, in the case of any date referred to in the foregoing
subdivision (i), and at least 20 days prior to the date therein specified, in
the case of the date referred to in the foregoing subdivision (ii).

                                   EXHIBIT A

THIS WARRANT AND ANY SHARES ACQUIRED UPON THE EXERCISE OF THIS WARRANT HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
SOLD OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT FILED UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION
UNDER SUCH ACT.

                                  EXERCISE FORM

                 (To be executed upon exercise of this Warrant)

     The undersigned hereby irrevocably elects to exercise the right,
represented by this Warrant, to purchase Warrant Shares and (check one):

     [ ]  herewith tenders payment for ____________ of the Warrant Shares to
          the order of SONICblue Incorporated in the amount of $______________
          in accordance with the terms of this Warrant; or

     [ ]  herewith tenders this Warrant for ____________ Warrant Shares pursuant
          to the Net Issue Exercise provisions of Section 1.2(b) of the Warrant.

The undersigned requests that a certificate (or certificates) for such Warrant
Shares be registered in the name of the undersigned and that such certificate
(or certificates) be delivered to the undersigned's address below.

The undersigned represents that (i) the Warrant Shares are being acquired for
the account of the undersigned for investment and not with a view to, or for
resale in connection with, the distribution thereof and that the undersigned has
no present intention of distributing or reselling such Warrant Shares; (ii) the
undersigned is aware of the Company's business affairs and financial condition
and has acquired sufficient information about the Company to reach an informed
and knowledgeable decision regarding its investment in the Company; (iii) the

background in financial and business matters that the undersigned is capable of
evaluating the merits and risks of this investment and protecting the
undersigned's own interests; (iv) the undersigned understands that the Warrant
Shares have not been registered under the Securities Act by reason of a specific
exemption from the registration provisions of the Securities Act, which
exemption depends upon, among other things, the bona fide nature of the
investment intent as expressed herein, and, because such securities have not
been registered under the Securities Act, they must be held indefinitely unless
subsequently registered under the Securities Act or an exemption from such
registration is available; (v) the undersigned is aware that the Warrant Shares
may not be sold pursuant to Rule 144 adopted under the Securities Act unless
certain conditions are met and until the undersigned has held the Warrant Shares
for the number of years prescribed by Rule 144; and (vi) the undersigned agrees
not to make any disposition of all or any part of the Warrant Shares unless and
until there is then in effect a registration statement under the Securities Act
covering such

proposed disposition and such disposition is made in accordance with said
registration statement, or the undersigned has provided the Company with an
opinion of counsel satisfactory to the Company, stating that such registration
is not required, or unless such Warrant Shares are sold in accordance with Rule
144 adopted under the Securities Act.
