                          Common Stock Purchase Warrant


                            Void After June 30, 2008


No. W-SVB-4.......                                            Las Vegas, Nevada
                                                              June 30, 2003


         VISEON, INC. (formerly RSI Systems, Inc.) (the "Company"), a Nevada
corporation, for value received, hereby certifies that HENRY S. MELLON an
individual, or registered assigns (the "Holder"), is entitled to purchase from
the Company Six Hundred Forty Four Thousand Five Hundred Ten (644,510) shares of
Common Stock of the Company (the "Warrant Quantity") duly authorized, validly
issued, fully paid and nonassessable shares of common stock, par value $0.01 per
share, of the Company (the "Common Stock") at the purchase price per share of
Thirty Cents ($0.30), at any time or from time to time prior to 5:00 p.m.
Central Standard time, on June 30, 2008 (the "Expiration Date"), all subject to
the terms, conditions and adjustments set forth below in this Warrant.

         This Warrant is the Warrant (the "Warrant", such term to include any
such warrants issued in substitution therefor) originally issued in connection
with the Third Amendment to that certain Loan and Security Agreement by and
between the Company and Silicon Valley Bank, dated December 5 2001. The Warrant
so issued evidences the right to purchase a number of shares of Common Stock
equal to the Warrant Quantity, subject to adjustment, if any, as provided
herein. Concurrently herewith the Company and Holder are also entering into that
certain Demand Registration Rights Agreement (hereinafter the "Registration
Rights Agreement") concerning the Warrant Shares. Certain capitalized terms used
in this Warrant are defined in Section 8, any capitalized term not defined in
Section 8 shall have the meaning ascribed in the Registration Rights Agreement;
references to an "Exhibit" are, unless otherwise specified, to one of the
Exhibits attached to this Warrant and references to a "Section" are, unless
otherwise specified, to one of the Sections of this Warrant.

1. Exercise of Warrant.

         1.1 Manner of Exercise. This Warrant may be exercised by the Holder, in
whole or in part, during normal business hours on any Business Day, by surrender
of this Warrant to the Company at its principal office, accompanied by the Form
of Subscription in substantially the form attached as Exhibit A to this Warrant
(or a reasonable facsimile thereof) duly executed by the Holder and accompanied
by payment, in cash, by wire transfer, certified or official bank check payable
to the order of the Company, or in the manner provided in Section 1.5 (or by any
combination of such methods), in the amount obtained by multiplying (a) the
number of shares of Common Stock designated in such Form of Subscription by (b)
Thirty Cents ($0.30), and such Holder shall thereupon be entitled to receive
such number of duly authorized, validly issued, fully paid and nonassessable
shares of Common Stock (or Other Securities) on the Effective Date of Exercise.

         1.2 When Exercise Effective. Each exercise of this Warrant shall be
deemed to have been effected immediately prior to the close of business on the
Effective Date of Exercise. At such time the Person or Persons in whose name or
names any certificate or certificates for shares of Common Stock (or Other
Securities) shall be issuable upon such exercise, as provided in Section 1.3,
shall be deemed to have become the Holder or holders of record thereof.

         1.3 Delivery of Stock Certificates, etc. As soon as practicable after
each exercise of this Warrant, in whole or in part, and in any event within ten
Business Days following the Effective Date of Exercise, the Company at its
expense (including the payment by it of any applicable transfer taxes) will
cause to be issued in the name of and delivered to the Holder hereof or, subject
to Section 7, as such Holder (upon payment by such Holder of any applicable
transfer taxes) may direct,

                  (a) a certificate or certificates for the number of duly
         authorized, validly issued, fully paid and nonassessable shares,
         including, if the Company so elects, fractional shares, of Common Stock
         (or Other Securities) to which such Holder shall be entitled upon such
         exercise plus, at the discretion of the Company, in lieu of any
         fractional share to which such Holder would otherwise be entitled, cash
         in an amount equal to the same fraction of the Current Market Price per
         share on the Business Day next preceding the date of such exercise, and

                  (b) in case such exercise is in part only, a new Warrant or
         Warrants of like tenor, calling in the aggregate on the face or faces
         thereof for the number of shares of Common Stock equal (without giving
         effect to any adjustment thereof) to the number of such shares called
         for on the face of this Warrant minus the number of such shares
         designated by the Holder upon such exercise as provided in Section 1.1.

         1.4 Company to Reaffirm Obligations. The Company will, at the time of
each exercise of this Warrant, upon the request of the Holder, acknowledge in
writing its continuing obligation to afford to such Holder all rights to which
such Holder shall continue to be entitled after such exercise in accordance with
the terms of this Warrant, provided that if the Holder shall fail to make any
such request, such failure shall not affect the continuing obligation of the
Company to afford such rights to such Holder.

         1.5 Payment by Application of Shares Otherwise Issuable. Upon any
exercise of this Warrant, the Holder may, at its option, instruct the Company,
by written notice accompanying the surrender of this Warrant at the time of such
exercise, to apply to the payment required by Section 1.1 such number of the
shares of Common Stock otherwise issuable to such Holder upon such exercise as
shall be specified in such notice, in which case an amount equal to the excess
of the aggregate Current Market Price of such specified number of shares on the
date of exercise over the portion of the payment required by Section 1.1
attributable to such shares shall be deemed to have been paid to the Company and
the number of shares issuable upon such exercise shall be reduced by such
specified number.

         1.6 Tax Basis. The Company and the Holder shall mutually agree as to
the tax basis of this Warrant for purposes of the Internal Revenue Code of 1986,
as amended (the "Code"), and the treatment of this Warrant under the Code by
each of the Company and the Holder shall be consistent with such agreement.

2. Common Stock Issuable Upon Exercise. This Warrant initially evidences the
right to purchase a number of shares of Common Stock equal to the Warrant
Quantity. The "Warrant Price" shall be fixed at Thirty Cents ($0.30) per share
of Common Stock received upon exercise of this Warrant.

3.       Consolidation, Merger, etc.

         3.1 Adjustments for Consolidation, Merger, Sale of Assets,
Reorganization, etc. In case the Company after the date hereof (a) shall
consolidate with or merge into any other Person and shall not be the continuing
or surviving corporation of such consolidation or merger, or (b) shall permit
any other Person to consolidate with or merge into the Company and the Company
shall be the continuing or surviving Person but, in connection with such
consolidation or merger, the Common Stock or Other Securities shall be changed
into or exchanged for stock or other securities of any other Person or cash or
any other property, or (c) shall transfer all or substantially all of its
properties or assets to any other Person, or (d) shall effect a capital
reorganization or reclassification of the Common Stock or Other Securities
(other than a capital reorganization or reclassification resulting in the issue
of Additional Shares of Common Stock), then, and in the case of each such
transaction, proper provision shall be made so that, upon the basis and the
terms and in the manner provided in this Warrant, the Holder, upon the exercise
hereof at any time after the consummation of such transaction, shall be entitled
to receive (at the aggregate Warrant Price in effect at the time of such
consummation for all Common Stock or Other Securities issuable upon such
exercise immediately prior to such consummation), in lieu of the Common Stock or
Other Securities issuable upon such exercise prior to such consummation, the
highest amount of securities, cash or other property to which such Holder would
actually have been entitled as a shareholder upon such consummation if such
Holder had exercised the rights represented by this Warrant immediately prior
thereto, subject to adjustments (subsequent to such consummation) as nearly
equivalent as possible to the adjustments provided for herein.

         3.2 Assumption of Obligations. Notwithstanding anything contained in
the Warrant or in the Registration Rights Agreement to the contrary, the Company
will not effect any of the transactions described in clauses (a) through (d) of
Section 3.1 unless, prior to the consummation thereof, each Person (other than
the Company) which may be required to deliver any stock, securities, cash or
property upon the exercise of this Warrant as provided herein shall assume the
obligations of the Company under this Warrant and the obligation to deliver to
such Holder such shares of stock, securities, cash or property as, in accordance
with the foregoing provisions of this Section 3, such Holder may be entitled to
receive.

4.       Financial and Business Information.

         4.1 Filings. During any period when the Company is a Public Company,
the Company will file on or before the required date (including all applicable
extensions) all required regular or periodic reports (pursuant to the Exchange
Act) with the Commission and will deliver to the Holder promptly upon their
becoming available one copy of each report, notice or proxy statement sent by
the Company to its stockholders generally, and of each regular or periodic
report (pursuant to the Exchange Act) and any registration statement, prospectus
or written communication (other than transmittal letters) (pursuant to the
Securities Act), filed by the Company with (i) the Commission or (ii) any
securities exchange on which shares of Common Stock are listed.

         4.2      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 (other than a regular
         periodic dividend payable in cash out of earned surplus in an amount
         not exceeding the amount of the immediately preceding cash dividend for
         such period) 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

                  (b) any capital reorganization of the Company, any
         reclassification or recapitalization of the capital stock of the
         Company or any consolidation or merger involving the Company and any
         other Person, any transaction or series of transactions in which more
         than 50% of the Voting Securities of the Company are transferred to
         another Person or any transfer, sale or other disposition of all or
         substantially all the assets of the Company to any other Person, or

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

the Company will mail to the Holder 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 such dividend,
distribution or right, and (ii) the date or expected date on which any such
reorganization, reclassification, recapitalization, consolidation, merger,
transfer, 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, consolidation,
merger, transfer, dissolution, sale, disposition, liquidation or winding-up.
Such notice shall be mailed at least ten (10) days prior to the date therein
specified.

5. Restrictions on Transfer.

         5.1 Restrictive Legends. Except as otherwise permitted by this Section
5, each Warrant (including each Warrant issued upon the transfer of any Warrant)
shall be stamped or otherwise imprinted with a legend in substantially the
following form:

         "THIS WARRANT AND ANY SECURITIES ACQUIRED UPON EXERCISE OF THIS WARRANT
         HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED,
         OR THE SECURITIES LAW OF ANY STATE AND MAY NOT BE SOLD, TRANSFERRED OR
         OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
         STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR
         PURSUANT TO AN APPLICABLE EXEMPTION TO THE REGISTRATION REQUIREMENTS OF
         SUCH ACT AND SUCH LAWS. THIS WARRANT AND SUCH SECURITIES MAY NOT BE
         SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT IN COMPLIANCE WITH
         THE CONDITIONS SPECIFIED IN THIS WARRANT."

Except as otherwise permitted by this Section 5, each certificate for Common
Stock (or Other Securities) issued upon the exercise of any Warrant, and each
certificate issued upon the transfer of any such Common Stock (or Other
Securities), shall be stamped or otherwise imprinted with a legend in
substantially the following form:

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE
         SECURITIES LAW OF ANY STATE, AND MAY NOT BE SOLD, TRANSFERRED OR
         OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
         STATEMENT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR
         PURSUANT TO AN APPLICABLE EXEMPTION TO THE REGISTRATION REQUIREMENTS OF
         SUCH ACT AND SUCH LAWS."

         5.2 Transfer to Comply With the Securities Act. Restricted Securities
may not be sold, assigned, pledged, hypothecated, encumbered or in any manner
transferred or disposed of, in whole or in part, except in compliance with the
provisions of the Securities Act and state securities or Blue Sky laws and the
terms and conditions hereof.

         5.3 Termination of Restrictions. The restrictions imposed by this
Section 5 on the transferability of Restricted Securities shall cease and
terminate as to any particular Restricted Securities (a) when a registration
statement with respect to the sale of such securities shall have been declared
effective under the Securities Act and such securities shall have been disposed
of in accordance with such registration statement, (b) when such securities are
sold pursuant to Rule 144 (or any similar provision then in force) under the
Securities Act, or (c) when, in the opinion of both counsel for the Holder and
counsel for the Company, such restrictions are no longer required or necessary
in order to protect the Company against a violation of the Securities Act upon
any sale or other disposition of such securities without registration
thereunder. Whenever such restrictions shall cease and terminate as to any
Restricted Securities, the Holder shall be entitled to receive from the Company,
without expense, new securities of like tenor not bearing the applicable legends
required by Section 5.1.

6. Reservation of Stock, etc. The Company shall at all times reserve and keep
available, solely for issuance and delivery upon exercise of this Warrant, the
number of shares of Common Stock (or Other Securities) from time to time
issuable upon exercise of this entire Warrant at the time outstanding. All
shares of Common Stock (or Other Securities) issuable upon exercise of any
Warrants shall be duly authorized and, when issued upon such exercise, shall be
validly issued and, in the case of shares, fully paid and nonassessable with no
liability on the part of the holders thereof, and, in the case of all
securities, shall be free from all taxes, liens, security interests,
encumbrances, preemptive rights and charges. The transfer agent for the Common
Stock, which may be the Company ("Transfer Agent"), and every subsequent
Transfer Agent for any shares of the Company's capital stock issuable upon the
exercise of any of the purchase rights represented by this Warrant, are hereby
irrevocably authorized and directed at all times until the Expiration Date to
reserve such number of authorized and unissued shares as shall be requisite for
such purpose. The Company shall keep copies of this Warrant on file with the
Transfer Agent for the Common Stock and with every subsequent Transfer Agent for
any shares of the Company's capital stock issuable upon the exercise of the
rights of purchase represented by this Warrant. The Company shall supply such
Transfer Agent with duly executed stock certificates for such purpose. All
Warrant certificates surrendered upon the exercise of the rights thereby
evidenced shall be canceled, and such canceled Warrants shall constitute
sufficient evidence of the number of shares of stock that have been issued upon
the exercise of such Warrants. Subsequent to the Expiration Date, no shares of
stock need be reserved in respect of any unexercised Warrant.

7. Registration and Transfer of Warrants, etc.

         7.1 Warrant Register; Ownership of Warrants. Each Warrant issued by the
Company shall be numbered and shall be registered in a warrant register (the
"Warrant Register") as it is issued and transferred, which Warrant Register
shall be maintained by the Company at its principal office or, at the Company's
election and expense, by a Warrant Agent or the Company's transfer agent. The
Company shall be entitled to treat the registered Holder of any Warrant on the
Warrant Register as the owner in fact thereof for all purposes and shall not be
bound to recognize any equitable or other claim to or interest in such Warrant
on the part of any other Person, and shall not be affected by any notice to the
contrary, except that, if and when any Warrant is properly assigned in blank,
the Company may (but shall not be obligated to) treat the bearer thereof as the
owner of such Warrant for all purposes. Subject to Section 9, a Warrant, if
properly assigned, may be exercised by a new holder without a new Warrant first
having been issued.

         7.2 Transfer of Warrants. Subject to compliance with Section 5, this
Warrant and all rights hereunder are transferable in whole or in part, without
charge to the Holder hereof, upon surrender of this Warrant with a properly
executed Form of Assignment attached hereto as Exhibit B at the principal office
of the Company. Upon any partial transfer, the Company shall at its expense
issue and deliver to the Holder a new Warrant of like tenor, in the name of the
Holder, which shall be exercisable for such number of shares of Common Stock
with respect to which rights under this Warrant were not so transferred.

         7.3 Replacement of Warrants. On receipt by the Company of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Warrant and, in the case of any such loss, theft or
destruction of this Warrant, on delivery of an indemnity agreement reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender of such Warrant to the Company at its principal office
and cancellation thereof, the Company at its expense shall execute and deliver,
in lieu thereof, a new Warrant of like tenor.

         7.4 Adjustments To Warrant Quantity. Notwithstanding any adjustment in
the Warrant Quantity or in the number or kind of shares of Common Stock
purchasable upon exercise of this Warrant, any Warrant theretofore or thereafter
issued may continue to express the same number and kind of shares of Common
Stock as are stated in this Warrant, as initially issued.

         7.5 Fractional Shares. Notwithstanding any adjustment pursuant to any
provision of this Warrant, the Company may, but shall not be required to, issue
fractions of shares upon exercise of this Warrant or to distribute certificates
which evidence fractional shares. In lieu of fractional shares, the Company
shall make payment to the Holder, at the time of exercise of this Warrant as
herein provided, in an amount in cash equal to such fraction multiplied by the
Current Market Price of a share of Common Stock on the date of Warrant exercise.

8. Definitions. As used herein, unless the context otherwise requires, the

shareholder of the Company, whether such obligation or liabilities are asserted
by the Company or by creditors of the Company. The Holder hereof shall not
acquire any rights as a shareholder of the Company until the day following the
