ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.
         -------------------------------------------------

         On September 25, 2001, Minnesota ASE purchased 2,245,000 shares (the
"Shares") of the Issuer's Common Stock from Celsius Inc., a Delaware corporation
("Celsius"), for a purchase price of $1,908,250 ($0.85 per share) pursuant to
the terms and conditions of that certain stock purchase agreement (the "Stock
Purchase Agreement"), undated and attached hereto as Exhibit A. Concurrently,
Minnesota ASE also loaned $2,600,000 to the Issuer for short term borrowing
needs pursuant to a Promissory Note, attached hereto as Exhibit B. The funds
used by Minnesota ASE to purchase the Shares and to loan $2,600,000 to the
Issuer consisted of working capital as well as loans by the Members. Minnesota
ASE's working capital consisted solely of the capital contributions of the
Members to Minnesota ASE. Mr. Kowalski contributed $750,000, as his capital
contribution, from his personal funds and loaned $690,000 to Minnesota ASE. Mr.
Auth contributed $500,000, as his capital contribution, from his personal funds
and loaned $460,000 to Minnesota ASE. Mr. Kuller contributed $300,000, as his
capital contribution, from his personal funds and loaned $276,000 to Minnesota
ASE. Mr. Gamst contributed $100,000, as his capital contribution, from his
personal funds and loaned $1,532,000 to the Issuer. Mr. Drenttel contributed
$50,000 (borrowed from Richfield Bank & Trust Co.), as his capital contribution,
and loaned $46,000 to Minnesota ASE. Mr. Weber contributed $50,000, as his
capital contribution, consisting of $25,000 from his personal funds and $25,000
borrowed from Wells Fargo, N.A. and loaned $46,000 to Minnesota ASE. All of the
foregoing loans to Minnesota ASE by the Members were funded by loans from the
National City Bank of Minneapolis to the Members except for Mr. Gamst who
borrowed $1,440,000 from Richard Hoel and $92,000 from National City Bank of
Minneapolis. It may well be the case that at some future date a portion of Mr.
Hoel's loan to Mr. Gamst will be repaid and then invested by Mr. Hoel into
equity ownership in Minnesota ASE. Documentation evidencing these loans to
Minnesota ASE by the Members are attached hereto as Exhibit C. Documentation
evidencing the loans to the Members by National City Bank of Minneapolis and Mr.
Hoel is attached hereto as Exhibit D. Documentation evidencing the loans to
Messrs. Drenttel and Weber to fund their equity contribution to Minnesota ASE is

ITEM 4.  PURPOSE OF TRANSACTION.
         ----------------------

         Minnesota ASE purchased the Shares with the intention of obtaining
majority control of the Issuer. Based upon the results of its ongoing review of
the Issuer's operations and economic and other considerations, including the
availability of, and alternate uses of, investment funds, Minnesota ASE may
determine to acquire additional Shares, to sell Shares, or to make other changes
in the operations of the Issuer including changing the number of directors on
the Board. However, aside from acquiring seats on the Issuer's Board and
increasing the number of directors on the Board, Minnesota ASE does not, at this
time, have any plans or proposals that would relate to, or would result in, any
transaction, change or other occurrence with respect to the Issuer or the Shares
as is listed on paragraphs (a) through (j) of Item 4 of Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.
         ------------------------------------

         (a) Minnesota ASE, LLC is the beneficial owner of 2,245,000 shares of
Common Stock, all of which have been acquired pursuant to the terms and
conditions of the Stock Purchase Agreement. The total number of shares of Common
Stock beneficially owned by Minnesota ASE, LLC represents 51.0% of the shares of
Common Stock outstanding.

         The number of shares beneficially owned and the percentages of
outstanding shares represented thereby, for Minnesota ASE, LLC have been

Issuer's most recent Quarterly Report on Form 10-Q for the quarterly period
ended June 30, 2001.

         (b) Minnesota ASE, LLC has the sole power to vote and to dispose of or
