Notes to interim period consolidated financial statements:

# 1.    Going Concern Uncertainty

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 Andus Inc., the majority
shareholder who has committed to support the Company financially for its normal management and corporate expenses at levels of
present expenditures until May 1, 2007. 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.

# 1.    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, 2005.

In the opinion of management, all adjustments have been made that are
necessary to fairly present the financial position, results of operations and cash flows of the Company.

# 2.    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 May 1, 2007, and not to demand repayment of the advances from shareholder before May 1, 2007. During
the 3 month period ended April 30, 2006, Andus Inc. advanced an additional $24,000 to the Company.

The General Manager, Larry Martin, administers the corporate affairs of the
Company and monitors residual business matters. During the 6 month period ended April 30, 2006, the Company paid Mr. Martin $2,700
for these services. An office is maintained in Chanhassen, 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 six months of fiscal year 2006 was $19,940 or $0.02 per
share, compared with a net loss of $28,499 or $0.03 per share for the same period last year.

No sales were recorded for the Company in the six months of fiscal years 2006
and 2005.

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 6 month period ended April 30, 2006, the Company paid Mr. Martin $2,700
for these services. An office is maintained in Chanhassen, 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 $1,688,500 available for
carryforwards, 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 2020.

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 May 1, 2007.

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-A 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 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.

# Item 3.    Controls and Procedures:

As of the end of the period covered by this report, the Cmpanys Chief
Executive Officer and Chief Financial Officer evaluated the effectiveness of the design and operation of the Companys
disclosure controls and procedures. Based upon this evaluation and in consultation with the Companys independent auditors,
the Chief Executive Officer and Chief Financial Officer have included have concluded that the Companys disclosure controls
and procedures currently in effect are effective in ensuring that information required to be disclosed by the Company in the
reports that it files or submits under the Securities and Exchange Act of 1934, as amended, is recorded, processed, summarized and
reported within the time period specified by the Securities and Exchange Commissions rules and forms.

The Chief Executive Officer and Chief Financial Officer have concluded that
the Companys disclosure controls and procedures are also effective to ensure that the information required to be disclosed
in the reports that the Company files or submits under the Exchange Act is accumulated and communicated to the Companys
management to allow timely decisions regarding required disclosure.

There have been no changes in the Companys internal control over
financial reporting.
