<PAGE>

          (d)  "Holder" shall mean the Person(s) then registered as the owner
                ------

     together with all additional securities received in payment of dividends or
     distributions on or splits of those securities or received as a result of
     the adjustments provided for in Paragraph 6 hereof.
                                     -----------

     3.   Exercise of Warrant. Subject to and in accordance with the provisions
          -------------------
and conditions hereof, this Warrant may be exercised from time to time in whole
or in part during the term of this Warrant as set forth in Paragraph 5 hereof.
                                                           -----------

     4.   Term of Warrant.  The term of this Warrant shall commence on the date
          ---------------
hereof and shall expire on the exercise in full of this Warrant by Holder or at
5:00 p.m. Tacoma, Washington time on the expiration of the Exercise Period.

     5.   Manner of Exercise.  Holder may exercise this Warrant in whole or in
          ------------------
part in accordance with the terms hereof by mailing or personally delivering to
the Company (i) this Warrant, (ii) a Notice of Exercise in the form of Exhibit I
                                                                       ---------

designated by the Company, or any combination of the foregoing, together with
all federal and state excise taxes applicable upon such exercise. Upon receipt
by the Company of this Warrant, the Notice of Exercise and such payment, this
Warrant shall be deemed to have been exercised with respect to the number of
shares of Common Stock subject to such exercise and specified in the Notice of
Exercise, and Holder shall thereupon become the holder of record of the shares
of Common Stock issuable upon such exercise, notwithstanding the fact that the
stock transfer books of the Company may then be closed or that certificates
representing such shares of Common Stock shall not then be actually delivered to
Holder.  As soon as practicable after any exercise, in whole or in part, of the
Warrant, and in any event within ten (10) Business Days thereafter, the Company
will deliver to Holder a stock certificate or certificates representing the
shares of Common Stock so purchased, with such certificate or certificates to be
in such name(s) and such denominations as Holder may specify in the Notice of
Exercise.  If this Warrant is exercised for less than all of the shares of
Common Stock subject hereto, the Company shall, upon such exercise and surrender
of this Warrant for cancellation, promptly execute and deliver to Holder a new
Warrant of like tenor evidencing the right of Holder to purchase the balance of
shares of Common Stock purchasable hereunder.

     6.   Adjustment Provisions.
          ---------------------

     (a)  If the Company shall, during the term hereof, (i) declare a dividend
and make a distribution on the Common Stock payable in shares of Common Stock,
(ii) subdivide or combine its outstanding shares of Common Stock, (iii) change
the number of shares of Common Stock issuable upon exercise of this Warrant by
reclassification, exchange or substitution, or (iv) reorganize the capital
structure of the Company by merger, reorganization, consolidation or sale of
assets, then this Warrant shall, after the happening of any such event, evidence
the right to purchase the number of shares of Common Stock or other securities
that would have been received as a result of that change with respect to the
shares of Common Stock as if such shares had been purchased under this Warrant
immediately before occurrence of such event.  Such adjustment shall be made
successively whenever any event listed above shall occur.  Any adjustment under
this subparagraph (a) shall become effective at the close of business on the
date any such event occurs (the  "Adjustment Date").

     (b)  If, during the term of this Warrant, the number of shares of Common
Stock of the Company is adjusted pursuant to subparagraph (a) above, then the
Exercise Price per share to be in effect after such Adjustment Date shall be
determined by multiplying the Exercise Price per share in effect immediately
prior to such Adjustment Date by a fraction, the numerator of which shall be the
number of shares of Common Stock outstanding at the closing of business on the
Business Day immediately preceding such Adjustment Date and the denominator of
which shall be the number of shares of Common Stock (or the equivalent amount of
other securities) outstanding at the opening of business on the first Business
Day after the Adjustment Date.

     (c)  Notice of Adjustment. The Company shall give notice of each adjustment
          --------------------
or readjustment of the number of shares of Common Stock or other securities
issuable upon exercise of this Warrant to Holder or of the Exercise Price per
share at the address set forth in Paragraph 16 hereof.
                                  ------------

     7.   Fractional Shares. No fractional shares or scrip representing
          -----------------
fractional shares of Common Stock shall be issued in connection with the
exercise of this Warrant, but the Company shall pay, in lieu of any fractional
share, a cash payment on the basis of the Exercise Price per share of the Common
Stock to be acquired pursuant to such exercise for such fractional share.

     8.   Restrictions on Transfer.  This Warrant is nontransferable and must be
          ------------------------
exercised by the original holder hereof.  The undersigned represents and
warrants that this Warrant is being purchased for his investment account without
a view towards the resale or distribution thereof in violation of applicable
securities laws.  It is understood that in case of subsequent sale of such
Warrant or the Warrant Securities under certain circumstances, such sale might
be deemed to constitute a public distribution within the meaning of, and require
registration under, the provisions of the Securities Act of 1933, as amended
(the "Act").

          (a)  The undersigned acknowledges and agrees that unless and until the
     Warrant and the Warrant Securities are registered under the Act, this
     Warrant and the Warrant Securities shall be "restricted securities" for
     purposes of Rule 144 under the Act.

                                      -4-
<PAGE>

          (b)  The undersigned shall, prior to any disposition or attempted
     disposition of the Warrant Securities, give written notice to the Company
     of his intention to effect such disposition and shall deliver to the
     Company an opinion of legal counsel (reasonably suitable to the Company)
     that the proposed disposition of the Warrant Securities may be effected
     without registration thereof under the Act and without taking any similar
     action under any other applicable securities laws, in which case Holder
     shall be entitled to dispose of the Warrant Securities in accordance with
     the terms of the notice delivered by the undersigned to the Company.

          (c)  Until the Warrant Securities are registered under the Act, each
     certificate evidencing the Warrant Securities so disposed of (and each
     certificate evidencing any undisposed of Warrant Securities) shall bear the
     following restrictive legend unless in the opinion of Company counsel such
     legend is not required:

          "The shares represented by this certificate have not been registered
          under the Securities Act of 1933, as amended (the "Act") or any state
          securities laws.  These shares may not be offered for sale, sold or
          otherwise transferred except pursuant to an effective registration
          statement under the Act or pursuant to an opinion of counsel delivered
          to the Company that an exemption from such registration is available
          for such sale or transfer."


          (d)  The undersigned understands and acknowledges that: (i) while the
     Company has an operating history, the Warrant and the Warrant Securities
     involve a high degree of risk of loss of the entire investment, and there
     is no assurance of any income from such investment; (ii) the Holder must
     bear the economic risk of an investment in the Warrant and the Warrant
     Securities for an indefinite period because the offer and sale of the
     Warrant and the Warrant Securities have not been registered under the Act
     or any state securities laws and are being offered and sold in reliance
     upon exemptions provided in the Act and state securities laws for
     transactions not involving any public offering and, therefore, cannot be
     resold or transferred unless they are subsequently registered under the Act
     and applicable state laws, or unless an exemption from such registration is
     available; (iii) there may not be a public market for the Warrant or the
     Warrant Securities in the future; (iv) the Holder is purchasing the Warrant
     and the Warrant Securities for investment purposes only for the Holder's
     account and not for the benefit of any other person or with any view toward
     the resale or distribution thereof; and (v) the Holder has no contract,
     undertaking, agreement or arrangement with any person to sell, transfer or
     pledge to such person or anyone else the Warrant or any of the Warrant
     Securities which the Holder is hereby purchasing or any part thereof, and
     the Holder has no present plans to enter into any such contract,
     undertaking, agreement or arrangement.

     9.   Stock to be Delivered upon Exercise. The Company will at all times
          -----------------------------------
keep available through the term of the Exercise Period, solely for delivery upon
the exercise of this Warrant, such

                                      -5-
<PAGE>

number of the shares of Common Stock or other securities as shall from time to
time be sufficient to effect the exercise of this Warrant.

     10.  Replacement of Warrant. Upon receipt 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, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company will execute and deliver, in lieu
thereof, a new warrant of like tenor to Holder.

     11.  Specific Performance.  The Company stipulates that the remedies at law
          --------------------
available to the holder of this Warrant in the event of any default or
threatened default by it in the performance of or compliance with any of the
terms of the Agreement are not and will not be adequate, and that such terms may
be specifically enforced by a decree for the specific performance of any
agreement contained herein or by an injunction against a violation of any of the
terms hereof or otherwise.

     12.  Applicable Law. THIS WARRANT SHALL BE GOVERNED BY, AND CONSTRUED IN
          --------------
ACCORDANCE WITH, THE LAWS OF THE STATE OF WASHINGTON, WITHOUT GIVING EFFECT TO
PRINCIPLES OF CHOICE OF LAWS OF SUCH STATE.

     13.  Entire Agreement. This Warrant constitutes the entire agreement
          ----------------
between the parties with respect to the subject matter hereof and supersedes any
and all prior agreements and understandings relating to the subject matter
hereof. This Warrant and any of the terms hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by the party
against which enforcement of such change, waiver, discharge or termination is
sought.

     14.  Successors and Assigns. This Warrant shall be binding upon and inure
          ----------------------
to the benefit of the Company and the undersigned and their respective
successors and permitted assigns; provided, however, nothing herein shall be
construed to permit assignment of the Warrant except in accordance with the
provisions herein.

     15.  Severability. Every provision of this Warrant is intended to be
          ------------
severable. If any term or provision hereof (or portion thereof) is determined to
be illegal or unenforceable for any reason whatsoever, such illegality or
unenforceability shall not affect any other term or provision (or portion
thereof) of this Warrant.

     16.  Notices.  All notices and other communications from the Company to the
          -------
holder of this Warrant shall be mailed by first class registered or certified
mail, postage prepaid, at the following address or at such other address as may
have been furnished to the Company in writing by such holder, or, until an
address is so furnished, to the address of the last holder of such Warrant who
has so furnished an address to the Company:
