                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 26.  Recent Sales of Unregistered Securities

         There has been no established trading market for the Registrant's
common stock since its inception on February 21, 1997. As of July 31, 2000,
Registrant had approximately 4,900 shareholders of record owning its 13,258,877
outstanding shares of common stock.

         On March 1, 1997, Registrant issued 9,000,000 shares (considering the
effect of the 3:1 and 5:1 stock splits) of restricted common stock to Mr. Dwayne
L. Fosseen, Chairman, CEO and Treasurer of Registrant and record and beneficial
owner of approximately 68.2% of Registrant's outstanding shares, in
consideration and exchange for his services in connection with the organization
of Registrant. Registrant claimed the exemption from registration in connection
with such private placement offering provided under Section 4(2) of the
Securities Act of 1933 and Rule 505 of Regulation D thereunder.

         From May 31, 1997 through April 30, 1998, Registrant issued and sold
(at $.33 per share) an aggregate of 2,572,200 shares (considering the effect of
the 3:1 and 5:1 stock splits) of common stock to 515 purchasers for
consideration of cash and services totaling $857,400. No underwriter was
employed in connection with the offering and sale of the shares. The Company
claimed the exemption from registration in connection with its Small Corporation
Offering Registration ("SCOR") offering provided under Section 3(b) of the
Securities Act of 1933 and Rule 504 of Regulation D promulgated thereunder. The
facts relied upon by the Registrant to make the ss.3(b) SCOR offering exemption
available include the following: (i) the aggregate offering price for the
offering of the shares of common stock did not exceed $1,000,000, less the
aggregate offering price for all securities sold within the twelve months before
the start of and during the offering of the shares in reliance on an exemption
under Section 3(b), or in violation of Section 5(a) of the 1933 Act; (ii) no
general solicitation or advertising was conducted by Registrant in connection
with the offering of any of the shares; and (iii) the Registrant has not been
since its inception (a) subject to the reporting requirements of Section 13 or
15(d) of the Securities Exchange Act of 1934, as amended; (b) an "investment
company" within the meaning of the Investment Company Act of 1940, as amended;
or (c) a development stage company that either has no specific business plan or
purpose or has indicated that its business plan is to engage in a merger or
acquisition with an unidentified company or companies, or other entity or
person.

         During April 1999, Registrant issued and sold (at $1.00 per share) an
aggregate of 58,600 shares (considering the effect of the 5:1 stock split) of
common stock to three employees and one consultant of Registrant for services
rendered totaling $58,000. No underwriter was employed in connection with the
offer and sale of the shares. Registrant claimed the exemption from registration
in connection with such private placement offering provided under Section 4(2)
of the Act and Rule 504 of Regulation D thereunder.

         During May through June 1999, Registrant issued and sold (at $5.00 per
share) an aggregate of 66,979 shares of common stock to 192 purchasers for cash
consideration totaling $334,895. As part of the unit offering, the 192
purchasers were also granted a warrant to purchase four shares of common stock
for every one share purchased; specifically, warrants to purchase 267,916 shares
were issued to non-affiliated investors at an exercise price of $5.00 per share,
expiring on June 15, 2002. No underwriter was employed in connection with the
offer and sale of the shares. Registrant claimed the exemption from registration
in connection with such offering provided under Section 4(2) of the Act and Rule
504 of Regulation D thereunder.

         From July 30, 1999 and continuing through July 30, 2000, Registrant
offered at $5.00 per share, up to 2,000,000 shares to Iowa residents. No
underwriter was employed in connection with such Iowa-Only Offering of shares.
1,561,248 shares of common stock were sold. Registrant claimed the exemption
from registration in such intra-state offering provided by Section 3(a) (11) of
the Securities Act of 1933. While (1) the shares were part of an issue
registered, offered and sold only to residents of Iowa, (2) Registrant is
incorporated in Iowa and (3) Registrant is doing business within Iowa, certain
of our Iowa-Only Offering Shares were resold by Iowa residents to non-Iowa
residents before "coming to rest" under Section 3 (a) (11) and/or Rule 147's
nine month standard. Accordingly, Registrant voluntarily elected to rescind the
Iowa-Only Offering. Upon completion of this Rescission Offer, approximately 3.7%
of the eligible Iowa-Only Offering Shareholders elected to rescind prior
purchase of shares.

         Since  inception,  Registrant  has  periodically   issued   options  in
circumstances unrelated to the Rule 504 offering described above:

The first relates to options issued to certain employees, affiliates and/or
service providers under employee benefit plans as defined in Rule 405, namely:

1.       According to the 1998 Common Stock Compensation Plan, in December 1998,
         options to purchase 367,400 shares were issued to four original
         employees for past services at the split-adjusted exercise price of
         $0.29 per share, expiring on December 31, 2008.

2.       According to the 1998 Common Stock Compensation Plan, in June 1999,
         options to purchase 100,000 shares were issued to J. Richard Relick,
         our Chief Operating Officer for past services at an exercise price of
         $4.25 per share, expiring on June 15, 2009.

3.       According to the 1999 Common Stock Compensation Plan, in November 1999,
         options to purchase 560,000 shares were issued to Wayne Allison, our
         President, and Darrell Jolley, our Chief Financial Officer at an
         exercise price of $5.00 per share, expiring on September 30, 2008 and
         vesting quarterly through September 30, 2003.

4.       According to the 2001 Common Stock Compensation Plan, in March 2001,
         options to purchase 9,160 shares were issued to six employees and/or
         consultants at an exercise price of $5.00 per share, expiring on March
         31, 2010.

The second relates to our March 2000 agreement with Duncan, Blum & Associates,
our securities counsel, to pay for legal services in warrants, in lieu of cash
for services, to purchase 30,000 shares at an exercise price of $0.01 per share,
 expiring on March 31, 2003.

Registrant claimed the exemption from registration in connection with each of
these private options and warrants transactions provided under Section 4(2) of
the Securities Act of 1933 and Rule 505 of Regulation D thereunder.
