                  (b)      If an Event of Default occurs and is continuing, the
Purchaser hereof may proceed to protect and enforce its rights by such
appropriate judicial proceedings against the Company as the Purchaser shall deem

advantage of any such law and covenants that it will not hinder, delay or impede
the execution of any power herein granted to the Purchaser, but will suffer and
permit the execution of every such power as though no such law has been enacted.

accrued and unpaid thereon, if any): (i) except as otherwise provided herein,
interest on the principal amount of this Debenture so called for redemption
shall cease to accrue; (ii) the principal amount of this Debenture so called for

                  (b)      Upon the Settlement Date the Company shall provide

                  (d)      In the event that the Purchaser negotiates the terms
of a settlement with the defendant in the Lawsuit, and requests that the Company
settle the Lawsuit based upon those terms (provided that those terms are within
the scope agreed upon in the Game Console Sublicense Agreement), but the Company
declines to do so (the "REFUSAL DATE"), the Company shall immediately repay all,
but not less than all, of the outstanding principal amount of this Debenture and
all accrued interest thereon prior to the Maturity Date in cash in immediately

Debenture shall be redeemed by the Company in an amount in cash equal to One
Hundred Twenty Five Percent (125%) of the outstanding principal amount of this
Debenture plus all accrued interest thereon (the "ALTERNATE SETTLEMENT

                  (e)      Within ten (10) days of the Refusal Date, the Company

redemption shall be redeemed by the Company at the Settlement Redemption Amount
or the Alternate Settlement Redemption Amount, as applicable.

         (8)      Conversion.

                  (a)      In addition to the Interest Debentures to be issued
pursuant to Section 3 hereof, at any time after the issuance of this Debenture
up until the Business Day occurring immediately preceding the earliest of the
Redemption Date, the Settlement Date, the Alternate Settlement Date, the Refusal
Date, the Maturity Date, or the date upon which this Debenture is converted in
full pursuant to Section 8 hereof, the Purchaser may at any time convert all or
a portion of the outstanding principal amount of this Debenture plus any and all
accrued interest to date (the "CONVERSION AMOUNT") into Common Stock of the
Company calculated as follows: that number of shares of Common Stock equal to:
(i) the Conversion Amount; divided by (ii) the Conversion Price then in effect.
Except as otherwise provided herein, the Conversion shall be deemed to have been
effected as of the close of business on the date on which the Conversion Notice
has been delivered to the Company pursuant to Section 8(b) hereof. Upon any
conversion the Common Stock shall be held by the Purchaser for a period of
thirty-two (32) days prior to any sale.

                  (b)      The Purchaser shall exercise its right of conversion
by delivering to the Company upon five (5) Business Days prior written notice
provided in accordance with Sections 9(f) and 10 hereof, a notice setting forth
the following: (i) the Conversion Amount; and (ii) the name or names (and
addresses) in which the Purchaser wishes the certificate or certificates of
shares of Common Stock to be issued (the "CONVERSION NOTICE").

                  As soon as possible after receipt by the Company of the
Conversion Notice (but in any event within five (5) Business Days), the Company
shall deliver to the Purchaser or its designee(s):

                           (i)      a certificate or certificates representing
the number of shares of Common Stock, issuable by reason of such Conversion in
such name or names as the Purchaser has specified; and

                           (ii)     in the event that the Conversion Amount is
less than the entire outstanding principal amount of this Debenture, a new
Debenture with identical terms shall be issued by the Company to the Purchaser
to reflect a deduction for the Conversion Amount.

                  (c)      The issuance of certificates for shares of Common
Stock shall be made without charge to the Purchaser for any issuance tax in
respect thereof or other cost incurred by the Company in connection with the
Conversion and the related issuance of shares thereof. Upon the Conversion, the
Company shall take all such actions as are necessary in order to insure

                                      -9-

<PAGE>

that such stock issuable with respect to the Conversion Notice shall be validly
issued, fully paid and nonassessable, free and clear of taxes, liens, charges
and encumbrances with respect to the issuance thereof.

                  (d)      The Company shall not close its books against the
transfer of any Common Stock issued or issuable upon delivery of the Conversion
Notice in any manner which interferes with the timely Conversion. The Company
shall assist and cooperate with the Purchaser to make any governmental filings
or obtain any governmental approval prior to or in connection with the
Conversion hereunder (including, without limitation, making any filings required
to be made by the Company).

                  (e)      If any fractional interest in a share of Common Stock
would, except for the provisions of this Section 8(e), be delivered upon the
Conversion, the Company, in lieu of delivering the fractional share therefor,
shall pay an amount to the Purchaser or its assignee(s) thereof equal to the
Market Price of such fractional interest as of the date of Conversion.

                  (f)      Nothing set forth in this Debenture or the Debenture
Purchase Agreement shall be construed to limit the number of conversions that
the Purchaser may elect to exercise prior to the earliest of the Redemption
Date, Settlement Repayment Date, or the Maturity Date.

         (9)      Conversion Price. (a) Subject to adjustment as set forth in
this Section 9, the initial price per share for the Conversion shall be $2.745
(the "CONVERSION PRICE").

                  (b)      Upon issuance, sale or grant by the Company of any
equity securities, equity linked securities or securities convertible into
equity securities at a purchase price less than the Conversion Price then owed
on the Debentures plus any accrued and unpaid interest thereon (the "OUTSTANDING
AMOUNT"), the Purchaser shall be entitled to a payment equal to 50% of the
Outstanding Amount. Notwithstanding the provisions set forth above, no
protection against dilutive issuances shall exist for (i) Common Stock issuable
upon conversion of any Series A Preferred Stock or warrants outstanding as of
the Closing Date; (ii) issuances of securities to employees, directors and
consultants as approved by the Company's Board of Directors, Compensation
Committee or similar committee of the Board of Directors performing such
functions pursuant to the Company's stock option and incentive plans as in
effect on the Closing Date, including the exercise of options granted under such
stock option and incentive plans; (iii) Common Stock or other securities issued
to equipment lessors, landlords, banks financial institutions or similar
entities in a transaction approved by the Company's Board of Directors, in an
amount not to exceed 5% of the shares of the Company calculated on a fully
diluted basis, in any twelve (12) month period; or (iv) Common Stock or other
securities issued pursuant to any transactions approved by the Company's Board
of Directors primarily for the purpose of research and development, distribution
or manufacture of the Company's products or services, in an amount not to exceed
5% of the shares of the Company calculated on a fully diluted basis, in any
twelve (12) month period.

                  (c)      Subdivision or Combination of Common Stock. If the
Company at any time subdivides (by any stock split, stock dividend,
recapitalization or otherwise) one or more classes of its outstanding shares of
Common Stock into a greater number of shares, the

                                      -10-

<PAGE>

applicable Conversion Price in effect immediately prior to such subdivision
shall be proportionately reduced, so that the number of shares of Common Stock
issuable on conversion of this Debenture shall be increased in proportion to
such increase of the aggregate number of shares of Common Stock outstanding and
if the Company at any time combines (by reverse stock split or otherwise) one or
more classes of its outstanding shares of Common Stock into a smaller number of
shares, the Conversion Price in effect immediately prior to such combination
shall be MULTIPLIED BY a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding immediately prior thereto and the denominator
of which shall be the number of shares of Common Stock outstanding immediately
thereafter.

                  (d)      Change of Control Transaction. Prior to the
consummation of a Change in Control or other liquidation of the Company, the
Purchaser, in its sole discretion, shall have the right to either (i) convert
this Debenture into the Company's Common Stock based upon the then applicable
Conversion Price pursuant to the provisions of Section 8; or (ii) receive, in
immediately available funds, prior to and in preference of the holders of any
other debt obligation, preferred security (other than the Series A Preferred
Stock), Common Stock or any other stock ranking junior to the Series A Preferred
Stock, an amount in cash equal to One Hundred Ten Percent (110%) of the
outstanding principal amount of this Debenture plus all accrued interest
thereon. Upon any such conversion the Common Stock shall be held by the
Purchaser for a period of thirty-two (32) days prior to any sale.

                  (e)      Certain Events. If any event occurs of the type
contemplated by the provisions of this Section 9 but not expressly provided for
by such provisions (including, without limitation, the granting of stock
appreciation rights, phantom stock rights or other rights with equity features),
then the Company's Board of Directors shall make an appropriate adjustment in
the then applicable Conversion Price so as to protect the rights of the
Purchaser; provided; however, that no such adjustment shall increase the
Conversion Price as otherwise determined pursuant to this Section 9 or decrease
the number of shares of issuable upon the Conversion.

                  (f)      Notices. Immediately upon any adjustment of the
Conversion Price, the Company shall give written notice thereof to the
Purchaser, setting forth in reasonable detail and certifying the calculation of
such adjustment.

                  (g)      Registration Rights. In the event of the issuance to
the Purchaser of any Common Stock in connection with one or more conversions in
whole or in part pursuant to Section 8 hereof, the Purchaser agrees that such
Common Stock shall be subject to that certain Registration Rights Agreement
between the Company and Purchaser dated as of the July 25 , 2003.

         (10)     General Provisions.

                  (a)      Subject to the prior optional redemption of this
Debenture pursuant to Section 6 hereof, the mandatory redemption of this
Debenture pursuant to Section 7 or the conversion of this Debenture pursuant to
Section 8 hereof, the Company agrees to repay the entire amount of this
Debenture in one lump sum on the Maturity Date.

                  (b)      All payments by the Company hereunder and under the
Debenture Purchase Agreement shall be made to the Purchaser at the Purchaser's
principal office on or before 1:00 P.M., Pacific Standard Time, on the due date
thereof in lawful money of the United States in immediately available funds. If
any such payment is required to be made on a day, which is not a Business Day,
such payment may be made on the next succeeding Business Day and such extension
of time shall be included in the computation of interest with respect thereto.
All such payments shall be made respective of, and without giving effect to, any
right of setoff, counterclaim or deduction, which the Company may have.

                  (c)      Notwithstanding any other term or condition of this
Debenture, in the event that it becomes unlawful for the Purchaser to maintain
this Debenture hereunder, then the Purchaser shall promptly notify the Company
thereof and the Company shall, within fifteen (15) Business Days of such notice,
prepay this Debenture, without penalty.

                  (d)      In addition to any rights now or hereafter granted
under applicable law or otherwise, and not by way of limitation of any such
rights, upon the occurrence and during the continuance of any Event of Default,
the Purchaser is hereby authorized at any time or from time to time, without
demand, protest or other notice of any kind to the Company or to any other
Person, any such notice being hereby expressly waived, to set off and to
appropriate and apply any and all amounts at any time held or owing by the
Purchaser to or for the credit or the account of the Company against and on
account of the obligations of the Company to the Purchaser under this Debenture
or under the Debenture Purchase Agreement, and all other claims of any nature or
description arising out of or connected with this Debenture or the Debenture
Purchase Agreement, irrespective of whether or not the Purchaser shall have made
any demand hereunder and although said obligations, liabilities or claims, or
any of them, shall be contingent or unmatured.

                  (e)      The Purchaser shall not be under any obligation to
marshal any assets in favor of the Company or any other party or against or in
payment of any or all of the Obligations. To the extent the Purchaser receives
any payment by or on behalf of the Company, which payment or any part thereof is
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be repaid to the Company or its estate, trustee, receiver,
custodian or any other party under any bankruptcy law, state or federal law,
common law or equitable cause, then to the extent of such payment or repayment,
the obligation or part thereof which has been paid, reduced or satisfied by the
amount so repaid shall be reinstated by the amount so repaid and shall be
included within the liabilities of the Company to the Purchaser as of the date
such initial payment, reduction or satisfaction occurred.

                  (f)      Except as otherwise expressly provided herein, all
notices, requests and demands to or upon the respective parties hereto to be
effective shall be in writing (including by telecopy), and shall be deemed to
have been duly given or made when delivered by hand, or five (5) days after
being deposited in the United States mail, postage prepaid, or, in the case of
telecopy notice, when sent, or, in the case of a nationally recognized overnight
courier service, one (1) Business Day after delivery to such courier service,
addressed, in the case of each party hereto, at its address specified opposite
its signature below, or to such other address as may be designated by any party
in a written notice to the other parties hereto.

                  (g)      This provisions of this Debenture shall be binding
upon and inure to the benefit of the Company and the Purchaser, and their
respective transferees, successors and assigns, except that neither party shall
have the right to assign or transfer any right or interest herein or hereunder
to a transferee other than an Affiliate of Purchaser or the Company without the
other party's prior written consent.

                  (h)      No failure or delay on the part of the Purchaser in
exercising any right, power or privilege hereunder or under the Debenture
Purchase Agreement and no course of dealing between the Company and the
Purchaser or the holder of this Debenture shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, power or privilege hereunder
or under the Debenture Purchase Agreement preclude any other or further exercise
thereof or the exercise of any other right, power or privilege hereunder or
thereunder. The rights and remedies herein expressly provided are cumulative and
not exclusive of any rights or remedies, which the Purchaser or the holder of
this Debenture would otherwise have. No notice to or demand on the Company in
any case shall entitle the Company to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the
Purchaser or the holder of this Debenture to any other or further action in any
circumstances without notice or demand.

                  (i)      This Debenture and the Debenture Purchase Agreement
and the rights and obligations of the parties hereunder and thereunder shall be
construed and controlled by the laws of the State of Washington, and each party
consents to exclusive jurisdiction and venue in the federal courts sitting in
King County, Washington, unless no federal subject matter jurisdiction exists,
in which case each party consents to exclusive jurisdiction and venue in the
Superior Court of King County, Washington. Each party waives all defenses of
lack of personal jurisdiction and forum non-conveniens. Process may be served on
either party in the manner authorized by applicable law or court rule. In any
action to enforce any right or remedy under this Debenture or the Debenture
Purchase Agreement or to interpret any provision of such agreements, the
prevailing party shall be entitled to recover its reasonable attorneys' fees,
costs and other expenses.

                  (j)      The headings of the sections, subsections, and
paragraphs of this Debenture have been added for convenience only and shall not
be deemed to be a part of this Debenture.

                  (k)      If any term, provision, covenant or restriction of
this Debenture is held by a board of arbitration or a court of competent
jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions set forth herein shall remain in
full force and effect and shall in no way be affected, impaired or invalidated,
and the parties hereto shall use their best efforts to find and employ an
alternative means to achieve the same or substantially the same result as that
contemplated by such term, provision, covenant or restriction. It is hereby
stipulated and declared to be the intention of the parties that they would have
executed the remaining terms, provisions, covenants and restrictions without
including any of those that may be hereafter declared invalid, illegal, void or
unenforceable.

Debenture, any term of this Debenture may be amended and the observance of any
term of this Debenture may be waived (either generally or in a particular
instance and either retroactively or prospectively), with the written consent of
the Company and the Purchaser. Any amendment or waiver effected in accordance
with this Section shall be binding upon the Company and Purchaser. No waivers of
or exceptions to any term, condition or provision of this Debenture, in any one
or more instances, shall be deemed to be, or construed as, a further or
continuing waiver of any such term, condition or provision.
