                        SECURITIES PURCHASE AGREEMENT

         This Securities Purchase Agreement (this "AGREEMENT") is entered
into as of June 4, 2003, between Applied Digital Solutions, Inc., a Missouri
corporation (the "COMPANY"), and Magellan International Ltd. (the
"PURCHASER").

         WHEREAS, the Company has registered with the Securities and
Exchange Commission (the "COMMISSION") the issuance of certain shares (the
"SHARES") of its common stock, $0.001 par value per share (the "COMMON
STOCK"), under a registration statement on Form S-1 (Registration No.
333-102165) (the "REGISTRATION STATEMENT").

         WHEREAS, subject to the terms and conditions set forth in this
Agreement, the Company desires to sell to the Purchaser and the Purchaser
desires to purchase from the Company up to eight million five hundred
thousand (8,500,000) Shares currently available under the Registration
Statement.

         NOW, THEREFORE, in consideration of the foregoing, the mutual
covenants contained in this Agreement and for other good and valuable
consideration the receipt and adequacy of which are hereby acknowledged, the
Company and the Purchaser agree as follows:

         1. SETTLEMENT DATES.
            ----------------

         (a) Settlement Dates. The closing, if any, of the purchase and sale
             ----------------
of the Shares under this Agreement will take place at the offices of Bryan
Cave LLP ("BRYAN CAVE"), 1290 Avenue of the Americas, New York, New York
10104, on the settlement dates set forth below. Subject to the terms and
conditions of this Agreement, the Shares will be issued, delivered and paid
for on up to three settlement dates (if any).

                  (1) The first settlement date (if any) will occur on the
fourth (4th) Trading Day (as defined below) following (and including) the
Press Release Date (the "FIRST SETTLEMENT DATE"). Subject to the terms and
conditions of this Agreement, on the First Settlement Date, the Company will
issue and deliver to the Purchaser and the Purchaser shall pay for 2,833,333
Shares (subject to adjustment, at the sole option of the Purchaser, in
accordance with and subject to the provisions of Sections 1(b)(2) or (3)).

                  (2) The second settlement date (if any) will occur on the
seventh (7th) Trading Day following (and including) the Press Release Date
(the "SECOND SETTLEMENT DATE"). Subject to the terms and conditions of this
Agreement, on the Second Settlement Date, the Company will issue and deliver
to the Purchaser and the Purchaser shall pay for 5,666,666 Shares less the
number of any Shares purchased by the Purchaser on the First Settlement Date
(subject to adjustment, at the sole option of the Purchaser, in accordance
with and subject to the provisions of Sections 1(b)(2) or (3)).

                  (3) The third settlement date (if any) will occur on the
tenth (10th) Trading Day following (and including) the Press Release Date
(the "THIRD SETTLEMENT DATE" and together with the First Settlement Date and
the Second Settlement Date, collectively, a

<PAGE>

"SETTLEMENT DATE"). Subject to the terms and conditions of this Agreement,
on the Third Settlement Date, the Company will issue and deliver to the
Purchaser and the Purchaser shall pay for 8,500,000 Shares less the number
of any Shares purchased by the Purchaser on the First Settlement Date and
the Second Settlement Date (subject to adjustment, at the sole option of the
Purchaser, in accordance with and subject to the provisions of Sections
1(b)(2) or (3)).

         (b) Per Share Purchase Price; Additional Share Elections.
             ----------------------------------------------------

                  (1) The purchase price for each Share issuable under this
Agreement on a Settlement Date (the "PER SHARE PURCHASE PRICE") shall equal
87.25% of the average of the VWAP's for the three Trading Days immediately
preceding such Settlement Date, but in no event less than the Floor Price
(as defined below).

                  (2) The Company is not required to sell, and the Purchaser
is not required to purchase, any Shares at a price that is less than the
Floor Price. If the Per Share Purchase Price with respect to a particular
Settlement Date is less than the Floor Price: (a) the Purchaser may, but is
not required to, require the Company to issue and sell to it up to the
maximum aggregate amount of Shares to be sold hereunder (it being understood
that not more than an aggregate of 8,500,000 Shares will be issued and sold
under this Agreement), and (b) if Purchaser elects to acquire such Shares
under (a) above, then the per share purchase price for such Shares shall
equal the Floor Price.

                  (3) At any time prior to 6:00 p.m. (New York time) on the
day preceding a Settlement Date, the Purchaser may elect by written notice
to the Company, to acquire (in addition to the Shares which it may be
obligated to acquire at such time) up to the maximum aggregate amount of
Shares to be sold hereunder (it being understood that not more than an
aggregate of 8,500,000 Shares will be issued and sold under this Agreement).

                  (4) Notwithstanding anything herein to the contrary, if
the VWAP on two consecutive Settlement Dates is less than $0.42, then, at
any time thereafter, Purchaser shall be entitled to terminate any and all of
its obligations under this Agreement by delivery of a written notice to the
Company to such effect.

                  (5) The Purchaser is not permitted to acquire Shares
hereunder to the extent that, giving effect to such proposed acquisition,
the beneficial ownership of the Common Stock by the Purchaser (together with
its affiliates and any other Persons whose beneficial ownership of Common
Stock would be aggregated with the Purchaser's for purposes of Section 13(d)
of the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")),
would exceed 9% of the total number of issued and outstanding shares of
Common Stock (including for such purpose the shares of Common Stock
potentially issuable upon such acquisition). Notwithstanding anything herein
to the contrary, the obligations of the parties hereto is subject to the
immediately preceding sentence and will be deemed automatically modified so
as to avoid any contravention thereof.

         (c) Deliveries on each Settlement Date. Subject to the terms and
             ----------------------------------
conditions of this Agreement, on each Settlement Date: (x) the Company will
deliver to the Purchaser, (A) via such Purchaser's DTC Account through the
Depository Trust Company DWAC system, a

such Settlement Date, and (B) a certificate, executed by the President of

all of the conditions set forth in Section 2, and (y) the Purchaser will,
upon receipt of such Shares in the DWAC system, deliver to the Company, an
amount in United States dollars equal to the product of (i) such number of
Shares, and (ii) the Per Share Purchase Price applicable to such Settlement
Date, via wire transfer of immediately available funds to an account
designated in writing by the Company for such purpose.

amendment or acceleration (with or without notice, lapse of time or both)
of, any agreement or indebtedness to which the Company is a party or by

material adverse effect on the Company or the transaction contemplated
hereby or (iii) result in a violation of any law, rule, regulation, order,
judgment, decree or other restriction of any court, governmental authority

         (d) Governing Law. All questions concerning the construction,
             -------------
validity, enforcement and interpretation of this Agreement will be governed
by and construed and enforced in accordance with the internal laws of the
State of New York, without regard to the principles of conflict of laws
thereof. Each party agrees that all legal proceedings concerning the
interpretations, enforcement and defense of the transactions contemplated by
this Agreement (whether brought against a party hereto or its respective
affiliates, directors, officers, shareholders, employees or agents) will be
exclusively commenced in the state and federal courts sitting in the City of
New York, Borough of Manhattan. Each party irrevocably submits to the
exclusive jurisdiction of the state and federal courts sitting in the City
of New York, Borough of Manhattan for the adjudication of any dispute
hereunder, and irrevocably waives, and agrees not to assert in any suit,
action or proceeding, any claim that it is not personally subject to the
jurisdiction of any such court or that such courts are an improper or
inconvenient forum. Each party hereto hereby irrevocably waives personal
service of process and consents to process being served in any such suit,
action or proceeding by mailing a copy thereof via registered or certified
mail or overnight delivery (with evidence of delivery) to such party at the
address in effect for notices to it under this Agreement and agrees that
such service will constitute good and sufficient service of process and
notice thereof. Nothing contained herein will be deemed to limit in any way
any right to serve process in any manner permitted by law. Each party
irrevocably waives, to the fullest extent permitted by applicable law, any
and all right to trial by jury in any legal proceeding arising out of or
relating to this Agreement or the transactions contemplated hereby. If
either party shall commence an action or proceeding to enforce any
provisions of this Agreement, then the prevailing party in such action or
proceeding will be reimbursed by the other party for its reasonable
attorneys fees and other reasonable costs and expenses incurred with the
investigation, preparation and prosecution of such action or proceeding.

         (e) Remedies. In addition to being entitled to exercise all rights
             --------
provided herein or granted by law, including recovery of damages, the
Purchaser and the Company will each be entitled to specific performance of
the others obligations under this Agreement. In furtherance thereof, the
parties agree that monetary damages may not be adequate compensation for any
loss incurred by reason of any such breach and hereby agrees to waive in any
action for specific performance of any such obligation the defense that a
remedy at law would be adequate.

         (f) Execution. This Agreement may be executed in two or more
             ---------
counterparts, all of which when taken together shall be considered one and
the same agreement and shall become effective when counterparts have been
signed by each party and delivered to the other party, it being understood
that both parties need not sign the same counterpart.

         (g) Assignment. Neither party shall assign this Agreement without
             ----------
the prior written consent of the other party hereto.

                                 EXHIBIT `A'

                          TERMS OF INDEMNIFICATION

         (a) INDEMNIFICATION BY THE COMPANY. The Company will indemnify and
             ------------------------------
hold harmless the Purchaser and the officers, directors, employees and
agents of the Purchaser, and each person, if any, who controls the Purchaser
within the meaning of Section 15 of the Securities Act or Section 20(a) of
the Securities Exchange Act, as amended (the "EXCHANGE ACT"), from and
against any losses, claims, damages, liabilities, costs and expenses
(including, without limitation, reasonable costs of defense and
investigation and all attorneys' fees and expenses) to which the Purchaser
and the officers, directors, employees and agents of the Purchaser, and each
person, if any, who controls the Purchaser may become subject, under the
Securities Act or otherwise, insofar as such losses, claims, damages,
liabilities and expenses (or actions in respect thereof) arise out of or are
based upon: (i) any untrue statement or alleged untrue statement of a
material fact contained, or incorporated by reference, in the Company
Registration Statement or any amendment or supplement to the Registration
Statement, or (ii) the omission or alleged omission to state in that
Registration Statement a material fact required to be stated therein or
necessary to make the statements therein not misleading (an "INDEMNIFIABLE
MATTER"). The Company will reimburse the Purchaser and the officers,
directors, employees and agents of the Purchaser and each such controlling
person promptly upon demand for any legal or other costs or expenses
reasonably incurred by the Purchaser and the officers, directors, employees
and agents of the Purchaser or the controlling person in investigating,
defending against, or preparing to defend against any claim relating to an
Indemnifiable Matter, except that the Company will not be liable to the
extent such claim, suit or proceeding which results in a loss, claim,
damage, liability or expense arises out of, or is based upon, an untrue
statement, alleged untrue statement, omission or alleged omission, included
in the Supplement in reliance upon, and in conformity with, written
information furnished by the Purchaser to the Company for inclusion in the
Supplement.

         (b) CONTRIBUTION. If for any reason the indemnification provided
             ------------
for in this Agreement is not available to, or is not sufficient to hold
harmless, an indemnified party in respect of any loss, claim, damage,
liability, cost or expense referred to in Paragraph (a), each indemnifying
party will, in lieu of indemnifying the indemnified party, contribute to the
amount paid or payable by the indemnified party, contribute to the amount
paid or payable by the indemnified party as a result of the loss, claim,
damage, liability, cost or expense: (i) in the proportion which is
appropriate to reflect the relative benefits received by the indemnifying
party, on the one hand, and by the indemnified party, on the other hand,
from the sale of stock which is the subject of the claim, action, suit or
proceeding which resulted in the loss, claim, liability, cost or expense or
(ii) if that allocation is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits of
the sale of stock, but also the relative fault of the indemnifying party and
the indemnified party with respect to the statements or omissions which are
the subject of the claim, action, suit or proceeding that resulted in the
loss, claim, damage, liability, cost or expense as well as any other
relevant equitable considerations.
