                              MIGHTY MACK USA, LTD
                    NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
                   For the Six Months Ended December 31, 1999

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

         CASH AND CASH EQUIVALENTS

         The Company considers all highly liquid debt instruments, purchased
         with an original maturity of three months or less, to be cash
         equivalents.

         ACCOUNTING FOR IMPAIRMENTS IN LONG-LIVED ASSETS:

         Long-lived assets and identifiable intangibles are reviewed for
         impairment whenever events or changes in circumstances indicate that
         the carrying amounts of assets may not be recoverable. Management
         periodically evaluates the carrying value and the economic useful life
         of its long-lived assets based on the Company's operating performance
         and the expected future undiscounted cash flows and will adjust the
         carrying amount of assets which may not be recoverable. Management
         believes that long-lived assets in the balance sheet are appropriately
         valued.

         PROPERTY AND EQUIPMENT

         Property and equipment is stated at cost. The cost of ordinary
         maintenance and repairs is charged to operations while renewals and
         replacements are capitalized. Depreciation is computed on the
         straight-line method over the following estimated useful lives:

<TABLE>
<S>                                                            <C>
           Furniture and fixtures                              7 years
           Computer equipment and software                    3- years
           Plant equipment                                      5 year
           Buildings                                          40 years
</TABLE>


         FEDERAL INCOME TAX:

         The Company accounts for income taxes under SFAS No. 109, which
         requires the asset and liability approach to accounting for income
         taxes. Under this approach, deferred income taxes are determined based
         upon differences between the financial statement and tax bases of the
         Company's assets and liabilities and operating loss carryforwards using
         enacted tax rates in effect for the years in which the differences are
         expected to reverse. Deferred tax assets are recognized if it is more
         likely than not that the future tax benefit will be realized.

         USE OF ESTIMATES:

         The preparation of financial statements, in conformity with generally
         accepted accounting principles, requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosure of contingent assets and liabilities at the
         date of the financial statements and the reported amounts of revenue
         and expenses during the reporting period. Actual results could differ
         from those estimates.

         TRADE NAMES AND PATENTS

         The Company has valued its trade names and patents at $100,000. These
         items are being amortized over a forty-year period.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

         FAIR VALUE OF FINANCIAL INSTRUMENTS

         The Company's financial instruments include cash, cash equivalents and
         notes payable. Estimates of fair value of these instruments are as
         follows:

                  Cash and cash equivalents - The carrying amount of cash and
                  cash equivalents approximates fair value due to the relatively
                  short maturity of these instruments.

                  Notes payable - The carrying amount of the Company's notes
                  payable approximate fair value based on borrowing rates
                  currently available to the Company for borrowings with
                  comparable terms and conditions.

NOTE 4 - INCOME TAXES

         Income taxes are provided for the tax effects of transactions reported
         in the financial statements and consist of taxes currently due plus
         deferred taxes related primarily to differences between the recorded
         book basis and tax basis of assets and liabilities for financial and
         income tax reporting. The deferred tax assets and liabilities represent
         the future tax return consequences of those differences, which will
         either be taxable or deductible when the assets and liabilities are
         recovered or settled. Deferred taxes are also recognized for operating
         losses that are available to offset future taxable income and tax
         credits that are available to offset federal income taxes. Due to the
         Company's net operating loss there are no income taxes currently due.
         Also, there were no material differences between recorded book basis
         and tax basis at September 30, 1999.

         The Company follows Financial Accounting Standards Board Statement No.
         109, "Accounting for Income Taxes" (SFAS #109), which requires, among
         other things, an asset and liability approach to calculating deferred
         income taxes. As of December 31, 1999, the Company has a net operating
         loss carry forward of $964,106 which has been fully reserved through a
         valuation allowance.

                   For the Six Months Ended December 31, 1999


NOTE 4 - INCOME TAXES (CONT.)

As of December 31, 1999, the Company had a net operating loss carry forward for
federal income tax purposes approximately equal to the accumulated deficit
recognized for book purposes, which will be available to reduce future taxable
income. The full realization of the tax benefit associated with the carry
forward depends predominantly upon the Company's ability to generate taxable
income during the carry forward period. Because of the current uncertainty of
realizing such tax assets in the future, a valuation allowance has been recorded
equal to the amount of the net deferred tax asset, which caused the Company's
effective tax rate to differ from the statutory income tax rate. The net
operating loss carry forward, if not utilized, will begin to expire in the year
2013.


NOTE 5 - NOTES PAYABLE

Notes payable consist of the following at December 31, 1999:

</TABLE>

NOTE 6 - PRODUCT AND ASSET PURCHASE AGREEMENT

         The Company entered into an agreement on February 1, 1999 to acquire
         substantially all of the products of Product Services Co., Inc. a
         Mississippi Corporation and Theodore Dickerson. This purchase also
         includes the real estate items of a storage plant and land at Valley
         Park, Mississippi. This purchase includes certain intellectual property
         assets made up of patents, trademarks, trade names and security
         interests. This purchase agreement is for $6,000,000 made up of
         $3,000,000 due up front and $3,000,000 due as a royalty payment
         comprised of three percent of the wholesale price of product up to a
         maximum of $3,000,000. The total balance of the royalty payment is due
         and payable by January 31, 2002 no matter whether the sales have
         occurred or not.

NOTE 7 - REALIZATION OF ASSETS

         The accompanying financial statements have been prepared in conformity
         with generally accepted accounting principles, which contemplates
         continuation of the Company as a going concern. However, the Company
         has sustained a substantial operation loss this year. As shown in the
         financial statements, the Company incurred a net loss of $964,106. At
         December 31, 1999, current liabilities exceed current assets by
         $2,202,888. The financial statements do not include any adjustments
         relating to the recoverability and classification of recorded assets,
         or the amounts and classification of liabilities that might be
         necessary in the event the Company cannot continue in existence.

         In view of these matters, realization of a major portion of the assets
         in the accompanying balance sheet is dependent upon continued
         operations of the Company, which in turn is dependent upon the
         Company's ability to meet its financial requirements, and the success
         of its future operations. Management believes that actions presently
         being taken to revise the Company's operating and financial
         requirements provide the opportunity for the Company to continue as a
         going concern.

NOTE 8 - RELATED PARTY TRANSACTION

         The officers and directors of the Company are involved in other
         business activities and may, in the future, become involved in other
         business opportunities. If a specific business opportunity becomes
         available, such persons may face a conflict in selecting between the

         In December, 1999 the Company sold $691,000 worth of 10% Convertible
         Debentures for $25,000 per Debenture. All of the Debentures were issued
         in accordance with the exemption from registration afforded by Sections
         4(2) and 4(6) of the Securities Act of 1933, as amended and Rule 506
         thereunder.

ITEM 2.  Managements Discussion and Analysis of Financial Condition and Results
         of Operations.

         Forward-Looking Statements

         The following discussion contains our forward-looking statements,
including, but not limited to, our business, prospects and results of operations
that are subject to certain risks and uncertainties posed by many factors and
events that could cause our actual business, prospects and results of operations
to differ materially from those that may be anticipated by such forward-looking
statements. Factors that may affect such forward-looking statements include,
without limitation: our ability to successfully develop new products for new
markets; the impact of competition on our revenues, changes in law or regulatory
requirements that adversely affect or preclude customers from using our products
for certain applications; delays our introduction of new products or services;
and our failure to keep pace with emerging technologies.

         When used in this discussion, words such as "believes", "anticipates",
"expects", "intends" and similar expressions are intended to identify
forward-looking statements, but are not the exclusive means of identifying
forward-looking statements. Readers are cautioned not to place undue reliance on
these forward-looking statements, which speak only as of the date of this
report. We undertake no obligation to revise any forward-looking statements in
order to reflect events or circumstances that may subsequently arise. Readers
are urged to carefully review and consider the various disclosures made by us in
this report and other reports filed with the Securities and Exchange Commission
that attempt to advise interested parties of the risks and factors that may
affect our business.

Results of Operations

         With the acquisition of the Mississippi Corporation, we began
generating revenues from our operations. As of the six months ended December 31,
1999, we had revenues of $21,464. We had total revenues for the fiscal year
ended June 30, 1999 of $4,736. Our total operating expenses for the six months
ended December 31, 1999 were $716,103. Our total operating expenses for the
fiscal year ended June 30, 1999 were $263,754. We had a net loss of $698,564,
compared to a net loss of $260,192 for the fiscal year end. The loss for the six
months ended December 31, 1999 was $0.04 per share, compared to a loss for the
fiscal year ended June 30, 1999 of $0.10 per share.

         We continue to negotiate the acquisition of all of the rights and
assets under the Purchase and Sale Agreement. Once this is complete, we believe
that the revenues from operations will grow during the remaining fiscal year as
we implement our business plan. However, if we are unable to complete the
Purchase and Sale Agreement, our future operations may be seriously impaired. In
any case, we believe that we will not be


<PAGE>   13

profitable during the current fiscal year. Our primary focus for this fiscal
year will be to complete the acquisition under the Purchase and Sale Agreement
and to build brand name recognition and product loyalty.

Liquidity and Capital Resources

         As of the end of the fiscal year, we had no cash or cash equivalents.
As of the six month period ended December 31, 1999, we had cash or cash
equivalents of $972. There was no significant change in working capital during
the six month period. In August 1999, we completed a private placement and
raised $691,000 and received loans from two of our affiliates of $117,394, all
of which was used to fund our operations.

         We believe that we still have inadequate working capital to pursue all
of our planned activities other than to internally expand the operations. We
plan to raise additional capital during the coming fiscal year.

         We do not intend to pay dividends in the foreseeable future.


                           PART II- OTHER INFORMATION

         ITEM 1. Legal Proceedings

                  Our subsidiary, Mighty Mack USA, Ltd., a private Mississippi

products, which rights were set forth in a written contract. The case has been
continued without a date for further proceedings. This case was pending in the
22nd Judicial District Court, Parish of St. Tammany, State of Louisiana.

         Otherwise, we know of no legal proceedings of a material nature pending

issued in accordance with the exemption from registration afforded by Sections
4(2) and 4(6) of the Securities Act of 1933, as amended and Rule 506 thereunder.
All of the investors are considered to be sophisticated and/or accredited
