$71,700.00                                                      Post Falls Idaho
                                                                June 1, 2004

         FOR VALUE RECEIVED, the undersigned LIFESTREAM TECHNOLOGIES, INC., a
Nevada corporation (the "Company"), hereby unconditionally promises to pay to
the order of CAPITAL SOUTH FINANCIAL SERVICES (the "Holder") at the designated
location of the Holder, in lawful money of the United States of America the
principal sum of $71,700.00, without interest, as hereinafter provided. This
Note evidences the Company's obligation to pay the outstanding portion of the
annual loan renewal fee for the period ending April 30, 2005.

         The principal amount of this Note shall be converted into common stock
of the Company on the effective date of a registration statement to be filed by
the Company, with the United States Securities and Exchange Commission (the
"Registration Statement"); provided that the Registration Statement permits the
Holder to publicly resell the shares of common stock into which this Note is to
be converted. The number of shares of common stock into which this Note shall be
converted (the "Conversion Shares") shall be computed by dividing the principal
amount of this Note by the closing bid price for the Company's common stock on
the over-the-counter Bulletin Board on the trading day immediately preceding the
effective date of the Registration Statement. No fractional shares will be
issued upon any conversion of this Note, and the number of Conversion Shares
shall be rounded up to the nearest whole share of common stock.

         If the Holder publicly resells the shares of common stock into which
this Note is convertible within two weeks from receipt of the stock certificate
and the proceeds received by the Holder is less than $71,700, then the Company
shall reimburse Holder in cash or additional shares of common stock for such
difference. If the Holder publicly resells the shares of common stock into which
this Note is convertible within two weeks from receipt of the stock certificate
and the proceeds received by the Holder upon public resale of the shares of
common stock into which this Note is converted is greater than $71,700, then the
Holder shall reimburse the Company in cash for such difference. If the Holder
does not sell the common shares received upon conversion of this Note within two
weeks of receipt of the stock certificate, no adjustments will be made.

         In the event of the occurrence of any of the following events prior to
the effective date of the Registration Statement, the Holder shall have the
right to declare the principal amount of this Note to be immediately due and
payable:

         (a)      the filing of a petition by the Company under Federal or State
                  bankruptcy laws or laws of similar scope generally affecting
                  the rights of creditors;

         (b)      the filing of a petition against the Company under Federal or
                  State bankruptcy laws or laws of similar scope generally
                  affecting the rights of creditors, which petition is not
                  dismissed within 60 days;

         (c)      the making of an assignment by the Company for the benefit of
                  creditors; or

         (d)      dissolution of the Company.

         This Note shall be governed by and construed in accordance with the
laws of the State of Nevada and shall be binding upon the successors, assigns,
heirs, administrators and executors of the Company and inure to the benefit of
the Holder, its successors, endorsees, assigns, heirs, administrators and
executors.
