        8. Security Act Provisions.

           8.1 Restricted Securities. Each of the Shareholders represents that
he, she, or it is aware that the shares issued or transferred to him, her, or it
will not have been registered pursuant to the Securities Act of 1933, as amended
(the "1933 Act"), or any state securities act, and thus will be restricted
securities

                                       -8-




as defined in Rule 144 promulgated by the Securities and Exchange Commission
(the "SEC"). Therefore, under current interpretations and applicable rules, he,
she, or it will probably have to retain such shares for a period of at least one
year and at the expiration of such one year period his, her, or its sales may be
confined to brokerage transactions of limited amounts requiring certain
notification filings with the SEC and such disposition may be available only if
the issuer is current in its filings with the SEC under the Securities Exchange
Act of 1934, as amended, or other public disclosure requirements.

           8.2 Non-distributive Intent. Each of the Shareholders covenants and
warrants that the shares received are acquired for his, her, or its own account
and not with the present view towards the distribution thereof and he, she, or
it will not dispose of such shares except (i) pursuant to an effective
registration statement under the 1933 Act, or (ii) in any other transaction
which, in the opinion of counsel acceptable to the issuer, is exempt from
registration under the 1933 Act, or the rules and regulations of the SEC
thereunder. In order to effectuate the covenants of this subsection 8.2, an
appropriate legend will be placed upon each of the certificates of common stock
of issued or transferred pursuant to this Agreement, and stop transfer
instructions shall be placed with the transfer agent for the securities.

           8.3 Evidence of Compliance with Private Offering Exemption. Each
of the Shareholders hereby represents and warrants that he, she, or it, either
individually or together with his, her, or its representative, has such
knowledge and experience in business and financial matters that he, she, or it
is capable of evaluating the risks of this Agreement and the transactions
contemplated hereby, and that the financial capacity of such party is of such
proportion that the total cost of such person's commitment in the shares would
not be material when compared with his, her, or its total financial capacity.
Upon the written request of the issuer of the securities issued or transferred
pursuant to this Agreement, any party hereto shall provide such issuer with
evidence of compliance with the requirements of any federal or state exemption
from registration. WWC and TWC shall each file, with the assistance of the other
and its respective legal counsel, such notices, applications, reports, or other
instruments as may be deemed by each of them to be necessary or appropriate in
an effort to document reliance on such exemptions, unless an exemption requiring
no filing is available in the particular jurisdiction, all to the extent and in
the manner as may be deemed by such parties to be appropriate.

        9. Employment Agreements. At closing, TWC shall offer to Richard Austin
and Barbara Austin employment agreements with salaries of $ 100,000 and
$40,000, respectively, in the forms attached hereto as Schedules "D-1" and

        10. Closing.

           10.1 Time and Place. The closing of this transaction ("closing")
shall take place at 150 Wright Brothers Drive, Suite 560, Salt Lake City, Utah,

hereto shall agree upon. Such date is referred to in this agreement as the
"closing date."

           10.2 Documents To Be Delivered by TWC and the Shareholders. At the
closing TWC and the Shareholders shall deliver to WWC the following documents:

               a. Certificates for the number of shares of common stock of TWC
in the manner and form required by subsection 1.1 hereof.


                                       -9-





               b. The certificate required pursuant to subsection 6.3 hereof.

               c. A written opinion from counsel for TWC dated as of the closing
date addressed to WWC satisfactory in form and substance to WWC to the effect
that TWC has good and marketable title to each asset owned by it free and clear
