purpose of defining the terms and provisions of the Option and the respective
rights and obligations thereunder, the Company and the Optionholder, for value
received, hereby agree as follows:

         Section 1. GRANT OF OPTION. The Company hereby grants to the

succession, assignment or authority to transfer. Upon any registration of
transfer, the Company shall execute and deliver a new Option to the person
entitled thereto.

                  2.3 LIMITATIONS ON TRANSFER OF THE OPTION. Subject to the
provisions of Section 12 hereof, the Option shall not be sold, transferred,
assigned or hypothecated by the Optionholder. Unless the context indicates

                  An Option bearing the signature of an individual who was at
the time of execution hereof the proper officer of the Company shall bind the
Company, notwithstanding that such individual shall have ceased to hold such
office prior to the delivery of such Option.

                  The Option shall be dated as of the date of signature thereof
by the Company either upon initial issuance or upon division, exchange,

<PAGE>

                  2.5 INVESTMENT REPRESENTATION OF THE OPTIONHOLDER. The
Optionholder represents and warrants to, and agrees with, the Company that the
Optionholder is acquiring the Option and the Shares issued upon exercise of the
Option for its own account, for investment, and not with a view to the sale or
distribution of any part thereof, and that the Optionholder does not have any
present intention of distributing or selling the same.

                  2.6 LEGEND ON OPTION SHARES. Each certificate for Shares
initially issued upon exercise of this Option shall bear a legend substantially
in accordance with the following:

"The securities represented by this Certificate have not been registered under
the Securities Act of 1933, as amended, and may not be sold, exchanged,
hypothecated or transferred in any manner except in compliance with Section 12
of the Option Agreement pursuant to which they were issued."

                  Any certificate issued at any time in exchange or substitution
for any certificate bearing such legend (except a new certificate issued upon
completion of a public distribution pursuant to a registration statement under
the Securities Act of 1933, as amended (the "Act") of the securities represented
thereby) shall also bear the above legend unless, in the opinion of counsel to
the Company, the securities represented thereby need no longer be subject to
such restrictions.

                  2.7 DEMAND REGISTRATION RIGHTS; NOTICE OF DEMAND. If the
Company receives a written notice from the Optionholders, upon exercise of the
options, demanding that the Company register such Optionholders' Shares issued
upon exercise, then the Company shall give written notice of such demand to all
Optionholders and will use its commercial best efforts to include in a
registration statement all Shares requested to be so included by all
Optionholders upon written notice to the Company at anytime within the Company's
current fiscal quarter in which the written notice of such demand was given.

                  2.8 REGISTRATION. Promptly after receipt of a demand for
registration as set forth in Section 2.7 of this Agreement, the Company shall
prepare and file with the SEC a registration statement, on a quarterly basis, on
the applicable form deemed most appropriate by the Company, for all Shares for
which registration is demanded, and the Company shall use its commercial best
efforts to cause such registration statement to become effective as soon as
practicable.

                  2.9 DEFERRAL OF REGISTRATION. If the Optionholders demand a
registration hereunder, the Company may defer filing such registration statement
with the SEC for up to thirty (30) days after the effective date of a
registration statement that the Company had filed with the SEC or had been
declared effective prior to the demand by the Optionholders if market conditions
do not warrant the sale of shares under registration at the time of the
effective date.

         Section 3. EXCHANGE OF OPTION CERTIFICATE. Any Option certificate may
be exchanged for another certificate or certificates, in amounts of no less than
1,000 Shares each, entitling the Optionholder to purchase a like aggregate
number of Shares as the certificate or certificates surrendered then entitled
such Optionholder to purchase. To exchange an Option certificate, the
Optionholder shall make such request in writing delivered to the Company, and
shall surrender, properly endorsed, the certificate evidencing the Option to be
so exchanged. Thereupon, the Company shall execute and deliver to the person
entitled thereto a new Option certificate as so requested.

         Section 4. TERM OF OPTION; EXERCISE OF OPTION. Subject to the terms of
this Agreement, the Optionholder shall have the right, at any time until 5:00
p.m., Pacific Standard Time, on July 3, 2010 (the "Termination Date"),
regardless of whether the Optionholder is employed by the Company, to purchase
from the Company up to the number of fully paid and nonassessable Shares which
the Optionholder may at the time be entitled to purchase pursuant to this
Agreement, upon surrender to the Company, at its principal executive offices of
the certificate evidencing the Option to be exercised, together with the
purchase form on the reverse thereof duly filled in and signed, and upon payment
to the Company of the Option Price (as defined and determined in accordance with
the provisions of Sections 8 and 9 hereof), for the number of Shares in respect
of which such Option is then exercised, but in no event for less than 1,000
Shares unless less than 1,000 Shares remain issuable upon exercise of the
Option. Payment of the aggregate Option Price shall be made in cash or by bank
certified check.

                                       2
<PAGE>

                  Upon such surrender of the Option and payment of such Option
Price as aforesaid, the Company shall issue and cause to be delivered with all
reasonable dispatch to or upon the written order of the Optionholder and in such
name or names as the Optionholder may designate a certificate or certificates
for the number of full Shares so purchased upon the exercise of the Option,
together with cash, as provided in Section 10 hereof, in respect of any
fractional Shares otherwise issuable upon such surrender. Such certificate or
certificates shall be deemed to have been issued and any person so designated to
be named therein shall be deemed to have become a holder of record of such
Shares as of the date of the surrender of the Option and payment of the Option
Price, as aforesaid, notwithstanding that the certificates representing such
Shares shall not actually have been delivered or that the stock transfer books
of the Company shall then be closed. The Option shall be exercisable, at the
election of the Optionholder, either in full or from time to time in part and,
in the event that a certificate evidencing the Option is exercised in respect of
less than all of the Shares specified therein at any time prior to the
Termination Date, a new certificate evidencing the remaining Option will be
issued by the Company.

         Section 5. PAYMENT OF TAXES. The Company will pay all documentary stamp
taxes, if any, attributable to the initial issuance of the Shares, provided,
however, that the Company shall not be required to pay any tax or taxes which
may be payable in respect of any secondary transfer of the Option or the Shares.

         Section 6. MUTILATED OR MISSING OPTION. In case the certificate or
certificates evidencing the Option shall be mutilated, lost, stolen or
destroyed, the Company shall, at the request of the Optionholder, issue and
deliver in exchange and substitution for and upon cancellation of the mutilated
certificate or certificates, or in lieu of and substitution for the certificate
or certificates lost, stolen or destroyed, a new Option certificate or
certificates of like tenor and representing an equivalent right or interest, but
only upon receipt of evidence satisfactory to the Company of such loss, theft or
destruction of such Option and of bond of indemnity, if requested, also
satisfactory in form and amount at the applicant's cost. Applicants for such
substitute Option certificate shall also comply with such other reasonable
regulations and pay such other reasonable charges as the Company may prescribe.

         Section 7. RESERVATION OF SHARES. There has been reserved, and the
Company shall at all times keep reserved so long as the Option remains
outstanding, out of its authorized Common Stock, such number of shares of Common
Stock as shall be subject to purchase under the Option. The Company will keep a
copy of this Agreement on file with every transfer agent for the Common Stock
and other securities of the Company issuable upon the exercise of the Option.
The Company will supply such transfer agent, if any, with duly executed shares
and other certificates for such purpose and will provide or otherwise make
available any cash which may be payable as provided in Section 10 hereof.

         Section 8. OPTION PRICE. The price per share (the "Option Price") at
which the Shares shall be purchasable upon the exercise of the Option shall be
$0.001 subject to further adjustment pursuant to Section 9 hereof.

         Section 9. ADJUSTMENT OF OPTION PRICE AND NUMBER OF SHARES. The number
and kind of securities purchasable upon the exercise of the Option and the
Option Price shall be subject to adjustment from time to time upon the happening
of certain events, as follows:

                  9.1 ADJUSTMENTS. The number of Shares purchasable upon
exercise of the Option and the Option Price shall be subject to adjustment as
follows:

                           (a) In case the Company shall (i) subdivide its
outstanding Common Stock, (ii) combine its outstanding Common Stock into a
smaller number of shares of Common Stock or (iii) issue by reclassification of
its Common Stock other securities of the Company, the number of Shares
purchasable upon exercise of the Option immediately prior thereto shall be
adjusted so that the Optionholder shall be entitled to receive the kind and
number of Shares or other securities of the Company which it would have owned or
would have been entitled to receive after the happening of such event or any
record date with respect thereto. Any adjustment made pursuant to this
subsection 9.1(a) shall become effective immediately after the effective date of
such event retroactive to the record date, if any, for such event.

                                       3
<PAGE>

                           (b) Whenever the number of Shares purchasable upon
the exercise of the Option is adjusted as provided in (a) above, the Option
Price payable upon exercise of the Option shall be adjusted by multiplying such
Option Price immediately prior to such adjustment by a fraction, of which the
numerator shall be the number of Shares purchasable upon the exercise of the
Option immediately prior to such adjustment, and of which the denominator shall
be the number of Shares so purchasable immediately thereafter.

                           (c) Whenever the number of Shares purchasable upon
the exercise of the Option or the Option Price is adjusted as herein provided,
the Company shall cause to be promptly mailed to the Optionholder by first class
mail, postage prepaid, notice of such adjustment or adjustments and a
certificate of the Company setting forth the number of Shares purchasable upon
the exercise of the Option and the Option Price after such adjustment, a brief
statement of the facts requiring such adjustment and the computation by which
such adjustment was made.

                           (d) For the purpose of this Section 8, the term
"Common Stock" shall mean (i) the class of stock designated as the Common Stock
of the Company at the date of this Agreement and (ii) any other class of stock
resulting from successive changes or reclassifications of such Common Stock
consisting solely of changes in par value, or from par value to no par value, or
from no par value to par value. In the event that at any time, as a result of an
adjustment made pursuant to this Section 9, the Optionholder shall become
entitled to purchase any shares of the Company other than Common Stock,
thereafter the number of such other shares so purchasable upon exercise of the
Option and the Option Price of such shares shall be subject to adjustment from
time to time in a manner and on terms as nearly equivalent as practicable to the
provisions with respect to the Shares contained in this Section 9.

                  9.2 NO ADJUSTMENT FOR DIVIDENDS. Except as provided in
subsection 9.1 hereof, no adjustment in respect of any dividends shall be made
during the term of the Option or upon the exercise of the Option.

                  9.3 PRESERVATION OF PURCHASE RIGHTS UPON RECLASSIFICATION,
CONSOLIDATION, ETC. In case of any consolidation of the Company with or merger
of the Company into another corporation or in case of any sale or conveyance to
another corporation of the property, assets or business of the Company as an
entirety or substantially as an entirety, the Company or such successor or
purchasing corporation, as the case may be, shall execute with the Optionholder
an agreement that the Optionholder shall have the right thereafter upon payment
of the Option Price in effect immediately prior to such action to purchase upon
exercise of the Option the kind and amount of shares and other securities and
property which the Optionholder would have owned or have been entitled to
receive after the happening of such consolidation, merger, sale or conveyance
had the Option been exercised immediately prior to such action. In the event of
a merger described in Section 368(a)(2)(E) of the Internal Revenue Code of 1986,
as amended, in which the Company is the surviving corporation, the right to
purchase Shares under the Option shall terminate on the date of such merger and
thereupon the Option shall become null and void but only if the controlling
corporation shall agree to substitute for the Option its option which entitles
the holder thereof to purchase upon its exercise the kind and amount of shares
and other securities and property which the Optionholder would have owned or had
been entitled to receive had the Option been exercised immediately prior to such
merger.

                  The agreements referred to in this subsection 9.3 shall
provide for adjustments, which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Section 9. The provisions of
this subsection 9.3 shall similarly apply to successive consolidations, mergers,
sales or conveyances.

                  9.4 STATEMENT OF OPTION. Where any adjustment which by reason
of Section 9.1(c) hereof is not required to be made immediately shall be carried
forward and taken into account in any subsequent adjustment and the Option
certificate or certificates theretofore or thereafter issued may continue to
express the same price and number and kind of shares as are stated in the Option
initially issuable pursuant to this Agreement.

         Section 10. FRACTIONAL INTERESTS. The Company shall not be required to
issue fractional Shares on the exercise of the Option. If any fraction of a
Share would, except for the provisions of this Section 10, be issuable on the
exercise of the Option (or specified portion thereof), the Company shall pay an
amount in cash equal to the then current market price multiplied by such
fraction.

                                       4

         Section 11. NO RIGHTS AS SHAREHOLDER; NOTICES TO OPTIONHOLDER. Nothing
contained in this Agreement or in any of the certificates representing the
Option shall be construed as conferring upon the Optionholder or its transferees
any rights as a shareholder of the Company, including the right to vote, receive
dividends, consent or receive notices as a shareholder in respect to any meeting
of shareholders for the election of directors of the Company or any other
matter. If, however, at any time prior to the expiration of the Option and prior
to its exercise, any of the following events shall occur:

                           (a) any action which would require an adjustment
pursuant to Section 9.1 or 9.3; or

                           (b) a dissolution, liquidation or winding up of the
Company (other than in connection with a consolidation, merger or sale of its
property, assets and business as an entirety or substantially as an entirety)
shall be proposed; then in any one or more of said events, the Company shall
give notice in writing of such event to the Optionholder as provided in Section
13 hereof at least 20 days prior to the date fixed as a record date or the date
of closing the transfer books for the determination of the shareholders entitled
to any relevant rights in connection with such action or for the determination
of shareholders entitled to vote on such proposed dissolution, liquidation or
winding up. Such notice shall specify such record date or the date of closing
the transfer books, as the case may be.

         Section 12. RESTRICTIONS ON TRANSFER. The Optionholder agrees that
prior to making any disposition of the Option or the Shares, the Optionholder
shall give written notice to the Company describing briefly the manner in which
any such proposed disposition is to be made; and no such disposition shall be
made if the Company has notified the Optionholder that in the opinion of counsel
satisfactory to the Optionholder (which may be Company counsel) a registration
statement or other notification or post-effective amendment thereto (hereinafter
collectively a "Registration Statement") under the Act of is required with
respect to such disposition and no such Registration Statement has been filed by
the Company with, and declared effective, if necessary, by the Securities and
Exchange Commission. Furthermore, the Optionholder acknowledges that the Shares
are restricted securities, as that term is defined in the Act and, as such, any
resale of the Shares as permitted by this Section 12 may only be made pursuant
to a Registration Statement under the Act or an exemption from registration
under the Act, including Rule 144 promulgated under the Act.

         Section 13. NOTICES. Any notice pursuant to this Agreement by the
Company or by the Optionholder shall be in writing and shall be deemed to have

               INCORPORATED UNDER THE LAWS OF THE STATE OF NEVADA

                  This certifies that, for value received, E. Douglas Mitchell,
the registered holder hereof or assigns (the "Optionholder") is entitled to

certain Option Agreement, dated as of July 3, 2000 (the "Option Price"), the

Option and the Option Price per share shall be subject to adjustment from time
to time as set forth in the Option Agreement referred to below.

                  This Option shall be subject to the following:

         "The securities represented by this Certificate have not been
         registered under the Securities Act of 1933, as amended, and may not be
         sold, exchanged, hypothecated or transferred in any manner except in
         compliance with Section 12 of the Option Agreement pursuant to which
         they were issued."
