# Notes to interim period
consolidated financial statements:

# 1.    Basis of Presentation

These interim period consolidated
financial statements have been prepared on the going concern basis which assumes that the
Company will continue in operation for the foreseeable future and be able to realize its
assets and discharge its liabilities in the normal course of business. There is
significant doubt about the appropriateness of the use of the going concern assumption
because the Company experienced a loss and negative cash flow in the current period. The
application of the going concern basis is dependent on the continued support of AndusInc., the majority shareholder who has committed to support the Company financially
for its normal management and corporate expenses at levels of present expenditures until
November 1, 2005. Management continues to pursue other business opportunities for the
Company including merger opportunities with other businesses, which may result in a
reverse-take-over of the company. However, there is no guarantee that management will be
successful in their endeavours.

These interim period consolidated
financial statements do not reflect adjustments that would be necessary if the going
concern basis was not appropriate. If the going concern basis was not appropriate for
these financial statements, then adjustments would be necessary to the carrying value of
assets, the reported revenues and expenses, and the balance sheet classifications used.

---

# 2.    Significant Accounting Policies

The unaudited interim period
consolidated financial statements have been prepared by the Company in accordance with
United States generally accepted accounting principles for interim financial statements
and do not conform in all respects to the requirements for generally accepted accounting
principles for annual financial statements.

The financial statements do not
include footnotes and certain financial presentations normally required under generally
accepted accounting principles; and, therefore, should be read in conjunction with the
Companys Annual Report on Form 10-KSB for the year-ended October 31, 2004.

# 3.    Related Party Transactions

The advances from shareholder are
payable to Andus Inc., the majority shareholder of the Company. The advances are
non-interest bearing, unsecured, and have no specific terms of repayment. Because the
Company has no means to generate the revenue necessary to pay its obligations to
regulatory bodies, directors, accountants and lawyers, Andus has undertaken to fund the
Companys normal management and corporate expenses at levels of present expenditures
until at least November 1, 2005, and not to demand repayment of the advances from
shareholder before November 1, 2005. Subsequent to January 31, 2005, Andus advanced an
additional $21,000 to be used to fund normal management and corporate expenses. These
advances are non-interest bearing.

The General Manager, Larry Martin,
administers the corporate affairs of the Company and monitors residual business matters.
During the period, the Company paid Mr. Martin $900 for these services. An office is
maintained in Minnetonka, Minnesota, which is provided free of charge by Mr. Martin. An
affiliate of Andus Inc., the majority shareholder, provides management and accounting
services at no charge to the Company.

# Item 2.    Managements Discussion of Financial Condition and Results of Operations.

The net loss for the three months of
fiscal year 2005 was $9,926 or $0.01 per share, compared with a net loss of $6,753 or
$0.01 per share for the same period last year.

No sales were recorded for the
Company in the three months of fiscal years 2005 and 2004.

---

The sale by Bison of its product
lines in prior years has essentially rendered Bison inactive.

The General Manager, Larry Martin,
administers the corporate affairs of the Company and monitors residual business matters.
During the period, the Company paid Mr. Martin $900 for these services. An office is
maintained in Minnetonka, Minnesota, which is provided free of charge by Mr. Martin. An
affiliate of Andus Inc., the majority shareholder, provides management and accounting
services at no charge to the Company.

The Company has income tax losses of
approximately $1,659,400 available for carry forwards, which may be used to reduce future
years taxable income and for which the benefit has not been recorded. These losses
expire between 2011 and 2019.

The Company has no means to generate
revenue necessary to pay its obligations to regulatory bodies, directors, accountants and
lawyers. In this regard, Andus Inc., the majority shareholder has committed to support the
Company for its normal management and corporate expenses at levels of present expenditure
until November 1, 2005.

Management continues to pursue other
business opportunities for the Company including merger opportunities with other
businesses which may result in a reverse-take-over of the Company. However, there is no
guarantee that management will be successful in their endeavours.

CAUTIONARY STATEMENT FOR PURPOSES OF
THE SAFE HARBOR PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF
1995. Except for historical matters, the matters discussed in this Form 10-QSB are
forward-looking statements based on current expectations, and involve risks and
uncertainties. Forward-looking statements include, but are not limited to, the operation
of the business and to statements regarding the general description of Managements
plan to seek other business opportunities including merger opportunities with other
businesses which may result in a reverse-take-over of the Company, and the manner in which
the Company may participate in such business opportunities.

The Company wishes to caution the
reader that there are many uncertainties and unknown factors which could affect its
ability to carry out its business plan to pursue other business opportunities for the
corporation. There is no guarantee that the Company will be successful in its endeavors.

| |  | One
of the omissions was the reference to the following paragraph to the notes to the interim
period consolidated financial statements as:
| |  | ------------------------------------------------------------------------------------------------------------------------------------------

| |  | KPMG
LLP, the Companys independent auditors, has not performed a quarterly review of the
unaudited consolidated financial statements for the ________ quarter ended ________, 2004.
| |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | In
addition the notes to the interim quarterly reports did not disclose that the Company is
able to mitigate going concern issues due to the continued financial support of the
majority shareholder of the Company. The majority shareholder has committed to support the
Company financially for its normal management and corporate expenses at levels of present
expenditures until November 1, 2005. Management continues to pursue other business
opportunities for the Company including merger opportunities with other businesses, which
may result in a reverse-take-over of the Company. However, there is no guarantee that
management will be successful in their endeavours.
| |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | The
Company amended and re-filed the quarterly reports for the three quarters of 2004.
| |  | --------------------------------------------------------------------------------------
