                                 VISTA.COM, INC.

____  ___, 2005
Warrant No. W-___

     1. Number of Shares Subject to Warrant. FOR VALUE RECEIVED, on and after
the date of this Warrant, and subject to the terms and conditions herein set
forth, ______________________________________________________, and its assigns
(the "HOLDER"), is entitled to purchase from Vista.com, Inc., a Washington
corporation (the "COMPANY"), at any time before the Termination Date (as defined
in Section 7 below), at an exercise price per share equal to $____ (the "WARRANT
PRICE"), ______ shares of Common Stock of the Company (the "WARRANT STOCK") upon
exercise of this Warrant pursuant to Section 5 hereof or conversion of this
Warrant pursuant to Section 6 hereof. The Warrant Price and number of shares of
Warrant Stock are subject to adjustment in accordance with Section 2.

     2. Adjustments and Notices. The Warrant Price and the number of shares of
Warrant Stock shall be subject to adjustment from time to time in accordance
with the following provisions:

          a. Subdivision, Stock Dividends or Combinations. In case the Company
shall at any time subdivide the outstanding shares of Warrant Stock or shall
issue a dividend in the form of securities with respect to the shares of Warrant
Stock, the Warrant Price in effect immediately prior to such subdivision or the
issuance of such dividend shall be proportionately decreased, and the number of
shares of Warrant Stock purchasable immediately prior to such subdivision or
issuance of dividend shall be proportionately increased, and in case the Company
shall at any time combine the outstanding shares of Warrant Stock, the Warrant
Price in effect immediately prior to such combination shall be proportionately
increased, and the number of Warrant Stock purchasable immediately prior to such
combination shall be proportionately decreased, effective at the close of
business on the date of such subdivision, dividend or combination, as the case
may be.

          b. Reclassification, Exchange, Substitution or Other Distribution.
Upon any reclassification, exchange, substitution or other event that results in
a change of the number


                                       1

<PAGE>

and/or class of the Warrant Stock issuable upon exercise of this Warrant or upon
the payment of a dividend in securities or property other than shares of Warrant
Stock, Holder shall be entitled to receive, upon exercise of this Warrant, the
number and kind of securities and property that Holder would have received if
this Warrant had been exercised immediately before the record date for such
reclassification, exchange, substitution or other event or immediately prior to
the record date for such dividend. 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 this Section 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.b shall similarly apply to successive reclassifications,
exchanges, substitutions or other events and successive dividends.

          c. Corporate Transaction. In case of: (i) any merger, share exchange
or consolidation of the Company, if following such merger, share exchange or
consolidation the holders of the Company's outstanding voting securities
immediately prior to such merger or consolidation own less than a majority of
the outstanding voting securities of the surviving corporation; (ii) any sale,
lease, exchange or other transfer in one transaction or a series of related
transactions of all or substantially all of the Company's assets other than a
transfer of the Company's assets to a majority-owned subsidiary; or (iii)
approval by the holders of the Warrant Stock of any plan or proposal for the
liquidation or dissolution of the Company (each, a "CORPORATE TRANSACTION"), the
Company shall deliver to Holder written notice of any proposed Corporation
Transaction at least ten (10) days prior to the effective date thereof.

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

     3. No Shareholder Rights. This Warrant, by itself, as distinguished from
any shares purchased hereunder, shall not entitle Holder to any of the rights of
a shareholder of the Company. Upon the exercise or conversion of this Warrant,
Holder hereby agrees, if requested by the Company, to execute and deliver a
counterpart signature page to, and otherwise agrees to become bound by, any
shareholder agreement then currently in effect.

     4. Representations of the Company and Reservation of Stock. This Warrant
has been duly and validly authorized, executed and delivered by the Company and
constitutes a valid and binding agreement of the Company enforceable against the
Company in accordance with its terms. All shares of Warrant Stock that may be
issued upon the exercise or conversion of this Warrant shall, upon issuance in
accordance with the terms hereof, be duly authorized, validly issued, fully paid
and nonassessable, and free of any liens and encumbrances, except for
restrictions on transfer provided for herein or under applicable federal and
state securities laws. On and after the date of this Warrant, the Company will
reserve from its authorized and unissued shares of Warrant Stock a sufficient
number of shares to provide for the issuance of the maximum amount of Warrant
Stock issuable upon the exercise or conversion of this Warrant.


                                       2

<PAGE>

Issuance of this Warrant shall constitute full authority to the Company's
officers who are charged with the duty of executing stock certificates to
execute and issue the necessary certificates for shares of Warrant Stock
issuable upon the exercise or conversion of this Warrant.

     5. Exercise of Warrant. This Warrant may be exercised in full or any
portion hereof at any time after the date hereof and prior to the Termination
Date for the number of shares of Warrant Stock for which this Warrant is then
exercisable, by the surrender of this Warrant, together with the Notice of
Exercise and Investment Representation Statement in the forms attached hereto as
Attachments 1 and 2, respectively, duly completed and executed at the principal
office of the Company, specifying the number of shares of Warrant Stock to be
purchased and accompanied by payment in full of the Warrant Price in cash or by
check with respect to such shares of Warrant Stock. This Warrant or any portion
hereof shall be deemed to have been exercised immediately prior to the close of
business on the date of its surrender for exercise as provided above, and the
person entitled to receive the shares of Warrant Stock issuable upon such
exercise shall be treated for all purposes as Holder of such shares of record as
of the close of business on such date. As promptly as practicable after such
date, but in any event within ten (10) business days thereafter, the Company
shall issue and deliver to the person or persons entitled to receive the same a
certificate or certificates for the number of full shares of Warrant Stock
issuable upon such exercise. The Company will report any "spread" on the
exercise of this Warrant by filing Form 1099-MISC with the Internal Revenue
Service as required by law. If this Warrant shall be exercised for less than the
total number of shares of Warrant Stock then issuable upon exercise, promptly
after surrender of this Warrant upon such exercise, the Company will execute and
deliver a new Warrant, dated the date hereof, evidencing the right of Holder to
the balance of the Warrant Stock purchasable hereunder upon the same terms and
conditions set forth herein.

     6. Conversion. In lieu of exercising this Warrant or any portion hereof,
Holder hereof shall have the right to convert this Warrant or any portion hereof
into Warrant Stock by executing and delivering to the Company at its principal
office the written Notice of Conversion and Investment Representation Statement
in the forms attached hereto as Attachments 2 and 3, specifying the portion of
this Warrant to be converted, and accompanied by this Warrant. The number of
shares of Warrant Stock to be issued to Holder upon such conversion shall be
computed using the following formula:

                                X = (P)(Y)(A-B)/A

     Where     X = the number of shares of Warrant Stock to be issued to Holder
                   for the portion of this Warrant being converted.

               P = the portion of this Warrant being converted expressed as a
                   decimal fraction.

               Y = the  total number of shares of Warrant Stock issuable upon
                   exercise of this Warrant in full.

               A = the fair market value of one share of Warrant Stock, which
                   shall mean (i) the fair market value of the Company's common
                   stock issuable upon


                                       3

<PAGE>

                   conversion of such share as of the last business day
                   immediately prior to the date the notice of conversion is
                   received by the Company, as determined in good faith by the
                   Company's Board of Directors, or (ii) if this Warrant is
                   being converted in conjunction with a public offering of
                   stock, the price to the public per share pursuant to the
                   offering.

               B = the Warrant Price on the date of conversion.

Any portion of this Warrant that is converted shall be immediately canceled.
This Warrant or any portion hereof shall be deemed to have been converted
immediately prior to the close of business on the date of its surrender for
conversion as provided above, and the person entitled to receive the shares of
Warrant Stock issuable upon such conversion shall be treated for all purposes as
the holder of such shares of record as of the close of business on such date. As
promptly as practicable after such date, the Company shall issue and deliver to
the person or persons entitled to receive the same a certificate or certificates
for the number of full shares of Warrant Stock issuable upon such conversion. If
this Warrant shall be converted for less than the total number of shares of
Warrant Stock then issuable upon conversion, promptly after surrender of this
Warrant upon such conversion, the Company will execute and deliver a new
Warrant, dated the date hereof, evidencing the right of Holder to the balance of
the Warrant Stock purchasable hereunder upon the same terms and conditions set
forth herein.

     7. Termination. This Warrant shall terminate on the "TERMINATION DATE,"
which shall mean the earlier to occur of:

          a. The closing of a Corporate Transaction; or

          b. April 14, 2007.

Warrant and, in the case of loss, theft or destruction, of indemnity reasonably

cancellation of the mutilated Warrant, the Company shall execute and deliver in
lieu thereof a new Warrant representing the right to purchase an equal number of
shares of Warrant Stock subject to the same terms and conditions set forth

     9. Accredited Investor. In connection with the receipt by Holder of this
Warrant, and any shares of Warrant Stock acquired in connection with the
exercise hereof, Holder hereby represents to the Company that such securities
are being acquired for investment and not with a view to, or for resale in
connection with, any distribution of such securities within the meaning of the
Securities Act of 1933, as amended (the "ACT"), or any applicable state
securities laws. By such representation, Holder means that it intends to hold
such securities for investment for its own account, and that it does not have
any present intention of disposing of all or any part of such shares at any
particular future time or upon the occurrence of any particular or presently
foreseeable event. Holder understands that these securities will not be
transferable merely upon the occurrence of a change in its personal
circumstances. Holder understands that neither this Warrant nor the securities
issued upon exercise of this Warrant will be registered under the Act, or any
applicable state securities laws, by reason of a specific exemption under the
provisions of such laws, which depends upon its intent. The undersigned hereby
represents and warrants that it is an "accredited investor" as such term is
defined in Rule 501 of Regulation D promulgated under the Act.

     10. Transfer of Warrant; Successors and Assigns. This Warrant may be
transferred or assigned by Holder hereof in whole or in part, provided that (i)
the transferor provides, at the Company's request, an opinion of counsel
satisfactory to the Company that such transfer does not require registration
under the Act and the securities law applicable with respect to any other
applicable jurisdiction, and (ii) the Company, in its sole discretion, consents
to such assignment or transfer. Notwithstanding the foregoing, Holder may
transfer this Warrant, in whole or in part, without compliance with such
restrictions to an affiliate of Holder. For purposes of this Warrant,


                                       5

<PAGE>

"affiliate" shall be deemed to include with respect to a holder (i) which is a
partnership or limited liability company, its partners, members, shareholders,
former partners, former members or an affiliated entity managed by the same
manager or managing partner or management company, or managed or owned by an
entity controlling, controlled by, or under common control with, such member or
manager or managing partner or management company, or (ii) which is an
individual, his or her spouse or lineal descendant or antecedent, or a trust or
trusts for the exclusive benefit of Holder or Holder spouse or lineal descendant
or antecedent, in each such case in connection with bona fide estate planning
purposes. Except as otherwise provided herein, the terms and conditions of this
Warrant shall inure to the benefit of and be binding upon the respective
permitted successors and assigns of the parties hereto. Nothing in this Warrant,
express or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and assigns any rights, remedies,
obligations, or liabilities under or by reason of this Warrant, except as
expressly provided in this Warrant.

     11. Lock-Up. By accepting this Warrant, Holder and its assigns hereby agree
that, in connection with an initial public offering and upon request of the
Company or one or more of the underwriters managing any underwritten offering of
the Company's securities, it will not sell, make any short sale of, loan, grant
any option for the purchase of, or otherwise dispose of any securities of the
Company (other than those included in the registration) without the prior
written consent of the Company or such underwriters, as the case may be, for
such period of time (not to exceed 180 days) from the effective date of such
registration as may be requested by the Company or such managing underwriters
and to execute an agreement reflecting and confirming the foregoing as may be
requested by the underwriters at the time of the initial public offering. To
enforce the agreement in this Section 11, the Company may impose stop-transfer
instructions to its transfer agent with respect to securities held by the
undersigned until the end of such period.

     12. Miscellaneous. The parties agree that this Warrant, and any disputes
arising hereunder, will be governed by and construed in accordance with the laws
of the state of Washington, without giving effect to any conflict of laws
principle to the contrary. The parties agree that venue for any dispute arising
under this Warrant will lie exclusively in the state or federal courts located
in King County, Washington, and the parties irrevocably waive any right to raise
forum non conveniens or any other argument that Washington is not the proper
venue. The parties irrevocably consent to personal jurisdiction in the state and
federal courts of the State of Washington. The headings in this Warrant are for
purposes of convenience and reference only, and shall not be deemed to
constitute a part hereof. Neither this Warrant nor any term hereof may be
changed or waived orally, but only by an instrument in writing signed by the
Company and Holder of this Warrant. Holder hereby agrees to indemnify the
Company against and to hold the Company harmless from any and all liabilities,
claims, losses, costs and expenses (including, without limitation, counsel fees
and disbursements) that may be asserted against the Company or incurred by it in
the event that any representation or agreement made herein shall be untrue or
shall be breached.

                                  Attachment 2

                       INVESTMENT REPRESENTATION STATEMENT

                            Shares of the Securities
                     (as defined in the attached Warrant) of
                                 VISTA.COM, INC.

     In connection with the purchase of the above-listed securities, the
undersigned hereby represents to Vista.com, Inc. (the "COMPANY") as follows:

          a. The securities to be received upon the exercise of the Warrant (the
"SECURITIES") will be acquired for investment for its own account, not as a
nominee or agent, and not with a view to the sale or distribution of any part
thereof, and the undersigned has no present intention of selling, granting
participation in or otherwise distributing the same, but subject, nevertheless,
to any requirement of law that the disposition of its property shall at all
times be within its control.

          b. The undersigned understands that the Securities issuable upon
exercise of the Warrant at the time of issuance may not be registered under the
Securities Act of 1933, as amended (the "ACT"), and applicable state securities
laws, on the ground that the issuance of such securities is exempt pursuant to
Section 4 (2) of the Act and state law exemptions relating to offers and sales
not by means of a public offering, and that the Company's reliance on such
exemptions is predicated on the undersigned's representations set forth herein.
The undersigned hereby represents and warrants that it is an "accredited
investor" as such term is defined in Rule 501 of Regulation D promulgated under
the Act.

          c. The undersigned agrees that in no event will it make a disposition
of any Securities acquired upon the exercise of the Warrant unless and until (i)
it shall have notified the Company of the proposed disposition and shall have
furnished the Company with a statement of the circumstances surrounding the
proposed disposition, and (ii) it shall have furnished the Company with an
opinion of counsel reasonably satisfactory to the Company and Company's counsel
to the effect that (A) appropriate action necessary for compliance with the Act
and any applicable state securities laws has been taken or an exemption from the
registration requirements of the Act and such laws is available, and (B) the
proposed transfer will not violate any of said laws. The undersigned agrees that
an appropriate restrictive legend shall be placed on the certificates issued in
connection with this exercise, referring to or stating explicitly the following
restrictions on transfer to which the undersigned hereby agrees:

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED ("ACT"), OR ANY
     APPLICABLE STATE SECURITIES LAWS AND MAY BE TRANSFERRED ONLY ON ONE OF THE
     FOLLOWING CONDITIONS: (A) THE SECURITIES HAVE BEEN MADE SUBJECT TO
     EFFECTIVE REGISTRATION UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES
     LAWS; (B) THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO IT
     THAT SUCH SECURITIES MAY BE TRANSFERRED WITHOUT REGISTRATION UNDER SAID ACT
     OR SUCH LAWS; OR (C) THE

<PAGE>

     SECURITIES AND EXCHANGE COMMISSION AND ANY APPLICABLE STATE SECURITIES
     REGULATORY AGENCY HAVE ISSUED IN RESPECT TO SUCH TRANSFER A "NO ACTION"
     LETTER OR EQUIVALENT INTERPRETIVE OPINION."

          d. The undersigned acknowledges that an investment in the Company is
highly speculative and represents that it is able to fend for itself in the
transactions contemplated by this Statement, has such knowledge and experience
in financial and business matters as to be capable of evaluating the merits and
risks of its investments, and has the ability to bear the economic risks
(including the risk of a total loss) of its investment. The undersigned
represents that it has had the opportunity to ask questions of the Company
concerning the Company's business and assets and to obtain any additional
information which it considered necessary, and has had all questions which have
been asked by it satisfactorily answered by the Company.

          e. The undersigned acknowledges that the Securities issuable upon
exercise of the Warrant must be held indefinitely unless subsequently registered
under the Act or an exemption from such registration is available. The
undersigned is aware of the provisions of Rule 144 promulgated under the Act
which permit limited resale of shares purchased in a private placement subject
to the satisfaction of certain conditions, including, among other things, the
existence of a public market for the shares, the availability of certain current
public information about the Company, the resale occurring not less than one (1)
year after a party has purchased and paid for the security to be sold, the sale
being through a "broker's transaction" or in transactions directly with a
"market makers" (as provided by Rule 144(f)) and the number of shares being sold
during any three-month period not exceeding specified limitations.
