            (e) The cost of the registration of the Registrable Securities will

shall be borne by the Investor.

      4. Adjustments. Subject to the provisions of Section 5 hereof, the number
and kind of securities purchasable upon the exercise of this Warrant and the
Exercise Price therefor shall be subject to adjustment from time to time upon
the occurrence of certain events, as follows:

            (a) Reclassification. In the case of any reclassification or change
of securities of the class issuable upon exercise of this Warrant (other than a
change in par value, or from par value to no par value, or from no par value to
par value, or as a result of a subdivision or combination), or in case of any
merger of the Company with or into another corporation (other than a merger with
another corporation in which the Company is the acquiring and the surviving
corporation and which does not result in any reclassification or change of
outstanding securities issuable upon exercise of this Warrant), or in case of
any sale of all or substantially all of the assets of the Company, the Company,
or such successor or purchasing corporation, as the case may be, shall duly
execute and deliver to the holder of this Warrant a new Warrant (in form and
substance reasonably satisfactory to the holder of this Warrant), or the Company
shall make appropriate provision without the issuance of a new Warrant, so that
the holder of this Warrant shall have the right to receive, at a total purchase
price not to exceed that payable upon the exercise of the unexercised portion of
this Warrant, and in lieu of the shares of Common Stock theretofore issuable
upon exercise of this Warrant, (i) the kind and amount of shares of stock, other
securities, money and property receivable upon such reclassification, change,
merger or sale by a holder of the number of shares of Common Stock then
purchasable under this Warrant, or (ii) in the case of such a merger or sale in
which the consideration paid consists all or in part of assets other than
securities of the successor or purchasing corporation, at the option of the
Holder of this Warrant, the securities of the successor or purchasing
corporation having a value at the time of the transaction equivalent to the fair
market value of the Common Stock at the time of the transaction. The provisions
of this subparagraph (a) shall similarly apply to successive reclassifications,
changes, mergers and transfers.

<PAGE>

            (b) Stock Splits, Dividends and Combinations. In the event that the
Company shall at any time subdivide the outstanding shares of Common Stock or
shall issue a stock dividend on its outstanding shares of Common Stock the
number of Shares issuable upon exercise of this Warrant immediately prior to
such subdivision or to the issuance of such stock dividend shall be
proportionately increased, and the Exercise Price shall be proportionately
decreased, and in the event that the Company shall at any time combine the
outstanding shares of Common Stock the number of Shares issuable upon exercise
of this Warrant immediately prior to such combination shall be proportionately
decreased, and the Exercise Price shall be proportionately increased, effective
at the close of business on the date of such subdivision, stock dividend or
combination, as the case may be.

      5. Notice of Adjustments. Whenever the number of Shares purchasable
hereunder or the Exercise Price thereof shall be adjusted pursuant to Section 3
hereof, the Company shall provide notice to the Holder setting forth, in
reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated, and the number
and class of shares which may be purchased thereafter and the Exercise Price
therefor after giving effect to such adjustment.

      6. Representations of the Company. The Company represents that all
corporate actions on the part of the Company, its officers, directors and
shareholders necessary for the sale and issuance of the Shares pursuant hereto
and the performance of the Company's obligations hereunder were taken prior to
and are effective as of the effective date of this Warrant.

      7. Representations and Warranties by the Holder. The Holder represents and
warrants to the Company as follows:

            (a) This Warrant and the Shares issuable upon exercise thereof are
being acquired for its own account, for investment and not with a view to, or
for resale in connection with, any distribution or public offering thereof
within the meaning of the Securities Act of 1933, as amended (the "Act"). Upon
exercise of this Warrant, the Holder shall, if so requested by the Company,
confirm in writing, in a form satisfactory to the Company, that the securities
issuable upon exercise of this Warrant are being acquired for investment and not
with a view toward distribution or resale.

            (b) The Holder understands that the Warrant and the Shares have not
been registered under the Act by reason of their issuance in a transaction
exempt from the registration and prospectus delivery requirements of the Act
pursuant to Section 4(2) thereof, and that they must be held by the Holder
indefinitely, and that the Holder must therefore bear the economic risk of such
investment indefinitely, unless a subsequent disposition thereof is registered
under the Act or is exempted from such registration.

            (c) The Holder has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
purchase of this Warrant and the Shares purchasable pursuant to the terms of
this Warrant and of protecting its interests in connection therewith.

            (d) The Holder is able to bear the economic risk of the purchase of
the Shares pursuant to the terms of this Warrant.

      7. Restrictive Legend.

            The Shares (unless registered under the Act) shall be stamped or
imprinted with a legend in substantially the following form:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND
NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF, AND
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH
SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR
UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY ACCEPTABLE TO IT
STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND
PROSPECTUS DELIVERY REQUIREMENTS OF THE ACT.

<PAGE>

     8. Transfer of Warrants. Notwithstanding anything to the contrary herein,
nothing shall prevent Holder from transferring the Warrant if the disposition
thereof is exempt from registration under the Act.

     9. Rights of Shareholders. No holder of this Warrant shall be entitled, as
a Warrant holder, to vote or receive dividends or be deemed the holder of any
Shares or any other securities of the Company which may at any time be issuable
on the exercise hereof for any purpose, nor shall anything contained herein be
construed to confer upon the holder of this Warrant, as such, any of the rights
of a stockholder of the Company or any right to vote for the election of
directors or upon any matter submitted to shareholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any
recapitalization, issuance of stock, reclassification of stock, change of par
value, consolidation, merger, conveyance, or otherwise) or to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until the
Warrant shall have been exercised and the Shares purchasable upon the exercise
hereof shall have become deliverable, as provided herein. The holder of this
Warrant will not be entitled to share in the assets of the Company in the event
of a liquidation, dissolution or the winding up of the Company.

     10. Notices. All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been duly made and
sent when delivered, or mailed by registered or certified mail, return receipt
requested:

            (a) If to a Holder, to the address of such Holder as shown on the
books of the Company; or

            (b) If to the Company, to the address set forth herein or to such
other address as the Company may designate by notice to the Holders.

      11. Governing Law. This Warrant and all actions arising out of or in
connection with this Agreement shall be governed by and construed in accordance
with the laws of the State of Washington, without regard to the conflicts of law
provisions of the State of Washington or of any other state.
