                            WARRANT TO PURCHASE STOCK

WARRANT TO PURCHASE 516,000          ISSUE DATE:                 APRIL 29, 1997
SHARES OF THE COMMON                 EXPIRATION DATE:            APRIL 30, 2002
STOCK OF INNOVA CORPORATION          INITIAL EXERCISE PRICE:     $0.29 PER SHARE
                                
THIS WARRANT CERTIFIED THAT, for the agreed upon value of $1.00 and for other
good and valuable consideration. GREYROCK BUSINESS CREDIT, A DIVISION OF
NATIONSCREDIT COMMERCIAL CORPORATION ("Holder") is entitled to purchase the
number of fully paid and non-assessable shares of the class of securities (the
"Shares") of the corporation (the "Company") at the initial exercise price per
Share (the "Warrant Price") all as set forth above and as adjusted pursuant to
Article 2 of this Warrant, subject to the provisions and upon the terms and
conditions set forth in this Warrant.


ARTICLE 1. EXERCISE.

 1.1 METHOD OF EXERCISE. Holder may exercise this Warrant by delivering a duly
executed Notice of Exercise in substantially the form attached as Appendix 1 to
the principal office of the Company. Unless Holder is exercising the conversion
right set forth in Section 1.2, Holder shall also deliver to the Company a check
for the aggregate Warrant Price for the Shares being purchased.

 1.2 CONVERSION RIGHT. In lieu of exercising this Warrant as specified in
Section 1.1, Holder may from time to time convert this Warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.4.

 1.3 FAIR MARKET VALUE. If the Shares are traded in a public market, the fair
market value of the Shares shall be the closing price of the Shares (or the
closing price of the Company's stock into which the Shares are convertible)
reported for the business day immediately before Holder delivers its Notice of
Exercise to the Company. If the Shares are not traded in a public market, the
Board of Directors of the Company shall determine fair market value in its
reasonable good faith judgment. The foregoing notwithstanding, if Holder advises
the Board of Directors in writing that Holder disagrees with such determination,
then the Company and Holder shall promptly agree upon a reputable investment
banking firm to undertake such valuation. If the valuation of such investment
banking firm is greater than that determined by the Board of Directors, then all
fees and expenses of such investment banking firm shall be paid by the Company.
In all other circumstances, such fees and expenses shall be paid by Holder.

 1.4 DELIVERY OF CERTIFICATE AND NEW WARRANT. Promptly after Holder exercises or
converts this Warrant, the Company shall deliver to Holder certificates for the
Shares acquired 


                                       1
   2
and, if this Warrant has not been fully exercised or converted and has not
expired, a new Warrant representing the Shares not so acquired.

1.5 REPLACEMENT OF WARRANTS. On receipt of evidence reasonably satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant and,
in the case of loss, theft or destruction, on delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of
mutilation, or surrender and cancellation of this Warrant, the Company at its
expense shall execute and deliver, in lieu of this Warrant, a new warrant of
like tenor.

1.6  REPURCHASE ON SALE, MERGER OR CONSOLIDATION OF THE COMPANY.

 1.6.1 "ACQUISITION". For the purpose of this Warrant, "Acquisition" means any
sale, license, or other disposition of all or substantially all of the assets of
the Company, or any reorganization, consolidation, or merger of the Company
where the holders of the Company's securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the
surviving entity after the transaction.

 1.6.2 ASSUMPTION OF WARRANT. If upon the closing of any Acquisition the
successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly.

 1.6.3 NONASSUMPTION. If upon the closing of any Acquisition the successor
entity does not assume the obligations of this Warrant and Holder has not
otherwise exercised this Warrant in full, then the unexercised portion of this
Warrant shall be deemed to have been automatically converted pursuant to Section
1.2 and thereafter Holder shall participate in the acquisition on the same terms
as other holders of the same class of securities of the Company.

ARTICLE 2.  ADJUSTMENTS TO THE SHARES.

2.1 STOCK DIVIDENDS, SPLITS, ETC. If the Company declares or pays a dividend on
its common stock (or the Shares if the Shares are securities other than common
stock) payable in common stock, or other securities, subdivides the outstanding
common stock into a greater amount of common stock, or, if the Shares are
securities other than common stock, subdivides the Shares in a transaction that
increases the amount of common stock into which the Shares are convertible, then
upon exercise of this Warrant, for each Share acquired, Holder shall receive,
without cost to Holder, the total number and kind of securities to which Holder
would have been entitled had Holder owned the Shares of record as of the date
the dividend or subdivision occurred.

2.2 RECLASSIFICATION, EXCHANGE OR SUBSTITUTION. Upon any reclassification,
exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of
this Warrant, the number and kind of securities and property that Holder would
have received for the Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. Such an
event shall include any automatic conversion of the outstanding or issuable
securities of the Company of the same class or series as the Shares to common
stock pursuant to the terms of the Company's Articles of Incorporation upon the
closing of a registered public offering of the Company's common stock. The
Company or its successor shall promptly issue to Holder a new Warrant for such
new securities or other property. The new Warrant shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in 


                                       2
   3
this Article 2 including, without limitation, adjustments to the Warrant Price
and to the number of securities or property issuable upon exercise of the new
Warrant. The provisions of this Section 2.2 shall similarly apply to successive
reclassifications, exchanges, substitutions, or other events.

2.3 ADJUSTMENTS FOR COMBINATIONS, ETC. If the outstanding Shares are combined or
consolidated, by reclassification or otherwise, into a lesser number of shares,
the Warrant Price shall be proportionately increased.

2.4 ADJUSTMENTS FOR DILUTING ISSUANCES. The Warrant Price and the number of
Shares issuable upon exercise of this Warrant or, if the Shares are Preferred
Stock, the number of shares of common stock issuable upon conversion of the
Shares, shall be subject to adjustment, from time to time in the manner set
forth on Exhibit A in the event of Diluting Issuances (as defined on Exhibit A).

2.5 NO IMPAIRMENT. The Company shall not, by amendment of its Articles of
Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all of the provisions of this Article 2
and in taking all such action as may be necessary or appropriate to protect
Holder's rights under this Article against impairment.

2.6 FRACTIONAL SHARES. No fractional Shares shall be issuable upon exercise or
conversion of the Warrant and the number of Shares to be issued shall be rounded
down to the nearest whole Shares. If a fractional share interest arises upon any
exercise or conversion of the Warrant, the Company shall eliminate such
fractional share interest by paying Holder amount computed by multiplying the
fractional interest by fair market value of a full Share.

2.7 CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the Warrant Price,
the company at its expense shall promptly compute such adjustment, and furnish
Holder with a certificate of its Chief Financial Officer setting forth such
adjustment and the facts upon which such adjustment is based. The Company shall,
upon written request, furnish Holder a certificate setting forth the Warrant
Price in effect upon the date thereof and the series of adjustments leading to
such Warrant Price.

ISSUER:               INNOVA CORPORATION

ADDRESS:              3325 SOUTH 116TH STREET
                      SEATTLE, WASHINGTON 98168

DATE:                 APRIL 29, 1997


THIS AGREEMENT is entered into as of the above date by and between GREYROCK
BUSINESS CREDIT, a division of NationsCredit Commercial Corporation
("Purchaser"), whose address is 10880 Wilshire Blvd. Suite 950, Los Angeles, CA
90024, and the above Company, whose address is set forth above.

                                    RECITALS

        A. Concurrently with the execution of this Antidilution Agreement, the
Purchaser is purchasing from the Company a Warrant to Purchase Stock (the
"Warrant") pursuant to which Purchaser has the right to acquire from the Company
the Shares (as defined in the Warrant).

        B. By this Antidilution Agreement, the Purchaser and the Company desire
to set forth the adjustment in the number of Shares issuable upon exercise of
the Warrant as a result of a Diluting Issuance (as defined in Exhibit A to the
Warrant).

        C. Capitalized terms used herein shall have the same meaning as set
forth in the Warrant.

        NOW, THEREFORE, in consideration of the mutual promises, covenants and
conditions hereinafter set forth, the parties hereto mutually agree as follows:

        1. DEFINITIONS. As used in this Antidilution Agreement, the following
terms have the following respective meanings:

        (a) "Option" means any right, option, or warrant to subscribe for,
purchase, or otherwise acquire common stock or Convertible Securities.


                                       1
   8
        (b) "Convertible Securities" means any evidence of indebtedness, shares
of stock, or other securities directly or indirectly convertible into or
exchangeable for common stock.

        (c) "Issue" means to grant, issue, sell, assume, or fix a record date
for determining persons entitled to receive, any security (including Options),
whichever of the foregoing is the first to occur.

        (d) "Additional Common Shares" means all common stock (including
reissued shares) issued (or deemed to be issued pursuant to Section 2) after the
date of the Warrant. Additional Common Shares does not include, however, any
common stock issued in a transaction described in Sections 2.1 and 2.2 of the
Warrant; any common stock Issued upon conversion of preferred stock outstanding
on the date of the Warrant; the Shares; or common stock Issued as incentive or
in a nonfinancing transaction to employees, officers, directors, or consultants
to the Company.

        (e) The shares of common stock ultimately Issuable upon exercise of an
Option (including the shares of common stock ultimately Issuable upon conversion
or exercise of a Convertible Security Issuable pursuant to an Option) are deemed
to be Issued when the Option is Issued. The shares of common stock ultimately
Issuable upon conversion or exercise of a Convertible Security (other than a
Convertible Security Issued pursuant to an Option) shall be deemed Issued upon
Issuance of the Convertible Security.

        2. DEEMED ISSUANCE OF ADDITIONAL COMMON SHARES. The shares of common
stock ultimately Issuable upon exercise of an Option (including the shares of
common stock ultimately Issuable upon conversion or exercise of a Convertible
Security Issuable pursuant to an Option) are deemed to be Issued when the Option
is Issued. The shares of common stock ultimately Issuable upon conversion or
exercise of a Convertible Security (other than a Convertible Security Issued
pursuant to an Option) shall be deemed Issued upon Issuance of the Convertible
Security. The maximum amount of common stock Issuable is determined without
regard to any future adjustments permitted under the instrument creating the
Options or Convertible Securities.

        3. ADJUSTMENT OF WARRANT PRICE FOR DILUTING ISSUANCES.

        3.1 WEIGHTED AVERAGE ADJUSTMENT. If the Company Issues Additional Common
Shares after the date of the Warrant and the consideration per Additional Common
Share (determined pursuant to Section 9) is less than the Warrant Price in
effect immediately before such Issue, the Warrant Price in effect immediately
before such Issue shall be reduced, concurrently with such Issue, to a price


                                       2
   9
(calculated to the nearest hundredth of a cent) determined by multiplying the
Warrant Price by a fraction:

        (a) the numerator of which is the amount of common stock outstanding
immediately before such Issue plus the amount of common stock that the aggregate
consideration received by the Company for the Additional Common Shares would
purchase at the Warrant Price in effect immediately before such Issue, and

        (b) the denominator of which is the amount of common stock outstanding
immediately before such Issue plus the number of such Additional Common Shares.

        3.2 ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment of the Warrant
Price, the number of Shares issuable upon exercise of the Warrant shall be
increased to equal the quotient obtained by dividing (a) the product resulting
from multiplying (i) the number of Shares issuable upon exercise of the Warrant
and (ii) the Warrant Price, in each case as in effect immediately before such
adjustment, by (b) the adjusted Warrant Price.

        3.3 SECURITIES DEEMED OUTSTANDING. For the purpose of this Section 3,
all securities issuable upon exercise of any outstanding Convertible Securities
or Options, warrants, or other rights to acquire securities of the Company shall
be deemed to be outstanding.

        4. NO ADJUSTMENT FOR ISSUANCES FOLLOWING DEEMED ISSUANCES. No adjustment
to the Warrant Price shall be made upon the exercise of Options or conversion of
Convertible Securities.

        5. ADJUSTMENT FOLLOWING CHANGES IN TERMS OF OPTIONS OR CONVERTIBLE
SECURITIES. If the consideration payable to, or the amount of common stock
Issuable by, the Company increases or decreases, respectively, pursuant to the
terms of any outstanding Options or Convertible Securities, the Warrant Price
shall be recomputed to reflect such increase or decrease. The recomputation
shall be made as of the time of the Issuance of the Options or Convertible
Securities. Any changes in the Warrant Price that occurred after such Issuance
because other Additional Common Shares were Issued or deemed Issued shall also
be recomputed.

        6. RECOMPUTATION UPON EXPIRATION OF OPTIONS OR CONVERTIBLE SECURITIES.
The Warrant Price computed upon the original Issue of any Options or Convertible
Securities, and any subsequent adjustments based thereon, shall be recomputed
when any Options or rights of conversion under Convertible Securities expire
without having been exercised. In the case of Convertible Securities or Options
for


                                       3
   10
common stock, the Warrant Price shall be recomputed as if the only Additional
Common Shares Issued were the shares of common stock actually Issued upon the
exercise of such securities, if any, and as if the only consideration received
therefor was the consideration actually received upon the Issue, exercise or
conversion of the Options or Convertible Securities. In the case of Options for
Convertible Securities, the Warrant Price shall be recomputed as if the only
Convertible Securities Issued were the Convertible Securities actually Issued
upon the exercise thereof, if any, and as if the only consideration received
therefor was the consideration actually received by the Company (determined
pursuant to Section 9), if any, upon the Issue of the Options for the
Convertible Securities.

        7. LIMIT ON READJUSTMENTS. No readjustment of the Warrant Price pursuant
to Sections 5 or 6 shall increase the Warrant Price more than the amount of any
decrease made in respect of the Issue of any Options or Convertible Securities.

        8. 30-DAY OPTIONS. In the case of any Options that expire by their terms
not more than 30 days after the date of Issue thereof, no adjustment of the
Warrant Price shall be made until the expiration or exercise of all such
