                   AMENDMENT NO. 1 TO THE SECURITIES PURCHASE
   AGREEMENT AND TRANSACTION DOCUMENTS BETWEEN ADVANCED TECHNOLOGY INDUSTRIES,
    INC., AND THE GROSS FOUNDATION, INC. FOR THE PURCHASE OF THE CONVERTIBLE
       DEBENTURES, DUE AUGUST 20, 2006, AND COMMON STOCK PURCHASE WARRANTS

         This Amendment No. 1 ("AMENDMENT") is made to that certain Securities
Purchase Agreement ("PURCHASE AGREEMENT") dated as of March 1, 2005 between
Advanced Technology Industries, Inc. (the "COMPANY"), and The Gross Foundation,
Inc. (the "Purchaser") for the purchase of the 9% Convertible Debentures, due
August 20, 2006 issued to the Purchaser (the "DEBENTURES"), and the Common Stock
Purchase Warrants issued to the Purchaser (the "Warrants"). Capitalized terms
used but not defined herein shall have the meanings given to such terms in the
Purchase Agreement.

         For good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereby agree as follows:

1.       EXERCISE PRICE OF THE WARRANTS.

         (a) Section 4(f) of the Purchase Agreement shall be amended and
restated as follows:

                  "(f) Warrants. For each $100,000 in Convertible Debentures
                  purchased by the Lender, the Company agrees to issue to the
                  Lender pro rata on each Closing Date transferable divisible
                  warrants (the "Warrants") for the purchase of an aggregate of
                  the Lender's pro rata portion of 1,428,571 Shares (based on
                  the amount loaned by the lender to all amounts loaned
                  hereunder) at an exercise price of $.10. The Warrants will
                  expire on the second annual anniversary of the Effective Date.
                  The Warrants shall be in the form annexed hereto as Annex VI.

         (b) Section 4(j)(ii)(C) of the Purchase Agreement shall be amended and
restated as follows:

                  "(C) the exercise price on all unexercised Warrants (unless
                  the Adjusted Exercise Price (as defined in the Warrants) is
                  then in effect) shall be adjusted to equal the lowest of (1)
                  the then existing exercise price of such Warrant and (2) 143%
                  of the Adjusted Conversion Price."

2.       CONVERSION PRICE OF THE DEBENTURES. Section 4(a) and (b) of the
         Debentures shall be amended and restated as follows:

         (a) Subject to Section 4(b), from and after the Certificate of
Incorporation Amendment Filing Date, the Holder of this Debenture is entitled,
at its option, to convert at any time the principal amount of this Debenture,
provided that the principal amount is at least US $10,000 (unless if at the time
of such election to convert the aggregate principal amount of all Debentures
registered to the Holder is less than Ten Thousand Dollars (US $10,000), then
the whole amount thereof) and accrued interest, into shares of Common Stock at a
conversion price (the "Conversion Price") for each share of Common Stock equal
to the lesser of (a) seven cents ($.07) as such price may be adjusted as
provided herein (the "Fixed Conversion Price") or (b) 75% of the Market Price on
the Conversion Date (as defined below) or Pre-Conversion Date (as defined
below), as the case may be, as such price may be adjusted as provided herein
(the "Variable Conversion Rate"). For purposes of this Section 4, the Market
Price shall be the average of the lowest ten (10) days closing bid prices (not
necessarily consecutive) of the Common Stock for the thirty (30) Trading Days
immediately preceding the Conversion Date, as reported by the Reporting Service,
or, in the event the Common Stock is listed on a stock exchange or traded on
NASDAQ, the Market Price shall be the closing prices on the exchange on such
dates, as reported in the Wall Street Journal. Notwithstanding the foregoing, if


                                       1

the Holder delivers a Notice of Conversion to the Company prior to the
Certificate of Incorporation Amendment Filing Date, the principal amount set
forth in such Notice of Conversion (each, a "Pre-Conversion Amount") and
interest accrued thereon up to the date the Holder faxes or otherwise delivers
the Notice of Conversion to the Company (the "Pre-Conversion Date"), shall, on
the Certificate of Incorporation Amendment Filing Date, automatically convert
(each, an "Automatic Conversion") into shares of Common Stock at a conversion
price equal to the Conversion Price in effect on the Pre-Conversion Date (the
"Pre-Conversion Price"), as such price may be adjusted as provided herein (but
no adjustment shall be made with respect thereto pursuant to Section 4(j) of the
Securities Purchase Agreement after the applicable Pre-Conversion Date) and
interest shall no longer accrue on any Pre-Conversion Amount on and after the
applicable Pre-Conversion Date (provided that if the Certificate of
Incorporation Amendment Filing Date does not occur prior to the Maturity Date
then interest on any Pre-Conversion Amount shall be calculated as if interest
accrued on such amount up to the Maturity Date).

                  (b) In the event that the Conversion Price shall be less than
$.07 as such price may be adjusted as provided herein (the "Redemption
Trigger"), the Holder may convert the principal amount of this Debenture or send
a Notice of Conversion prior to the Certificate of Incorporation Amendment
Filing Date only if the Holder emails a notice to the Company, ATT:
AMK@LTDNETWORK.COM and samuelsonjim@hotmail.com, advising the Company of its
intention to convert all or a specified amount of the principal amount of this
Debenture ("Stated Amount") within the fourteen (14) day period (the "Redemption
Period") after delivery of such notice ("Notice Date"); provided that the Holder
shall not be entitled to submit a Notice of Conversion (as defined below) until
after the Reply Date (as defined below). Not later than the end of the next
business day following the Notice Date (the "Reply Date"), the Company shall
notify the Holder by email (CG@CGMAIL.NET) and fax (718-851-3511) whether it
elects to redeem the Stated Amount in cash in lieu of permitting the Holder to
so convert ("Reply Notice"). In the event the Company does not timely deliver a
Reply Notice, or delivers a Reply Notice but elects not to redeem the Stated
Amount, it shall not be permitted to redeem the Stated Amount during the
Redemption Period. In the event the Company elects to redeem the Stated Amount,
then thereafter with respect to each Notice of Conversion delivered during the
Redemption Period, the Company shall pay an amount in immediately available
funds (each a "Redemption Amount") equal to (a) 150% of principal amount of this
Debenture that is subject to conversion in such applicable Notice of Conversion,
plus (b) accrued and unpaid interest with respect to such principal amount up to
the Redemption Date, and shall be paid to the Holder by the close of the third
(3rd) business day following the date on which the Holder faxes or otherwise
delivers such Notice of Conversion to the Company (any such date of redemption,
the "Redemption Date") in accordance with Section 5; provided that the aggregate
of all such principal amounts under all such Notices of Conversion delivered
during the Redemption Period shall not exceed the Stated Amount. In the event
the payment of the Redemption Amount is not timely made on the Redemption Date,
any right of redemption contained in this Section 4(b) shall thereafter
permanently terminate with respect to this Debenture, and the Company shall,
with respect to any conversions submitted during the Redemption Period, cause to
be issued to the Holder 105% of the number of shares of Common Stock otherwise
required to be delivered to the Holder in accordance with Section 4(a) with
respect to conversions of the lesser of (x) the Stated Amount and (y) and the
principal amount of this Debenture requested to be converted as set forth in any
Notices of Conversion. If the Holder does not deliver a Notice of Conversion
during the Redemption Period it must comply with the provisions of this Section
4(b) with respect to any intended conversions following the Redemption Period.
Nothing contained in this Section 4 (b) shall be deemed to obligate the Holder
to submit a Notice of Conversion during the Redemption Period. Furthermore, the
Holder may elect to forgo the redemption right set forth herein, and submit a
Notice of Conversion with a Conversion Price above the Redemption Trigger .


         3.       CLOSING DATE.

                  Section 6(a) of the Purchase Agreement is amended to read as
follows:

         "(a) The Closing Date, as to the initial $150,000 of the Purchase Price
(the "Initial Closing Date") shall occur on the date which is the first Trading
Day after each of the conditions contemplated by Sections 7 and 8 hereof shall
have either been satisfied or been waived by the party in whose favor such


                                       2

conditions run. The Closing Date as to the remaining $150,000 of the Purchase
Price (the "Second Closing Date") (which shall be deposited with the Escrow
Agent on the Initial Closing Date) shall occur on April 5, 2005."


4.       EFFECT ON PURCHASE AGREEMENT. Except as expressly set forth above, all
         of the terms and conditions of the Purchase Agreement, the Debentures
         and the Warrants shall continue in full force and effect after the
         execution of this Amendment, and shall not be in any way changed,
         modified or superseded by the terms set forth herein.
