                        SECURITIES PURCHASE AGREEMENT

                  This Securities Purchase Agreement (this "AGREEMENT") is
entered into as of December 2, 2003, between Applied Digital Solutions,

                  WHEREAS, the Company has registered with the Securities

STOCK"), under a registration statement on Form S-1 (Registration No.
333-106300) (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 761,905 Shares

Company and the Purchaser agree as follows:

                  1.   Settlement Dates.

                  (a)  Settlement Dates. The closing, if any, of the purchase

                       (2)   The second settlement date (if any) will occur

Company will issue and deliver to the Purchaser, and the Purchaser shall
purchase from the Company, 571,428 Shares less the aggregate number of
Shares purchased by the Purchaser on all previous Settlement Dates (as
defined below) (subject to adjustment, at the sole option of the Purchaser,
in accordance with and subject to the provisions of Sections 1(b)(2) and
(3)).

                       (4)   The fourth settlement date (if any) will occur
on the thirteenth (13th) Trading Day following (and including) the Press
Release Date (the "FOURTH SETTLEMENT DATE", and together with the First
Settlement Date, Second Settlement Date, Third Settlement Date and Fourth
Settlement Date, collectively, the "SETTLEMENT DATES", and each
individually, a "SETTLEMENT DATE"). Subject to the terms and conditions of
this Agreement, on the Fourth Settlement Date, the Company will issue and
deliver to the Purchaser, and the Purchaser shall purchase from the Company,
761,905 Shares less the aggregate number of Shares purchased by the
Purchaser on all previous Settlement Dates (subject to adjustment, at the
sole option of the Purchaser, in accordance with and subject to the
provisions of Sections 1(b)(2) and (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 87.00% of the average of the VWAP for the three Trading Days
immediately preceding such Settlement Date.

                       (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
shall be under no further obligation to purchase any Shares that would have
been purchased on the applicable Settlement Date, but may, at its option,
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 761,905 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 761,905 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

                                     2

<PAGE>
<PAGE>

4.999% 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.
                       ----------------------------------

                       (1)   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 number of Shares equal to the applicable number of
Shares being acquired on such Settlement Date, and (B) a certificate,
executed by the President of the Company, to the effect that the Company has
complied with and is in compliance with 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.

                       (2)   In addition to any other rights available to the
Purchaser, if on a Settlement Date, the Company fails to deliver to such
Purchaser's DTC Account the number of Shares being acquired on such
Settlement Date, and if the Purchaser purchases (in an open market
transaction or otherwise) shares of Common Stock to deliver in satisfaction
of a sale by the Purchaser of the shares that the Purchaser anticipated
receiving from the Company (a "Buy-In"), then, in the Purchaser's sole
discretion, the Company shall, within three Trading Days after the
Purchaser's request, either (i) pay cash to the Purchaser in an amount equal
to the Purchaser's total purchase price (including brokerage commissions, if
any) for the shares of Common Stock so purchased (the "Buy-In Price"), at
which point the Company's obligation to deliver such Shares shall terminate,
or (ii) promptly honor its obligation to deliver to the Purchaser a
certificate or certificates representing such Common Stock and pay cash to
the Purchaser in an amount equal to the excess (if any) of the Buy-In Price
over the product of (A) such number of shares of Common Stock, times (B) the
Closing Price on the date of the event giving rise to the Company's
obligation to deliver such certificate.

Company hereby makes the following representations and warranties to the
Purchaser:

the transactions contemplated hereby. The Company is duly qualified to
conduct business and is in good standing as a foreign corporation or other
entity in each jurisdiction in which the nature of the business conducted or
property owned by it makes such qualification necessary, except where the
failure to do so would not reasonably be expected to have a material adverse

by the Company or its shareholders for the Company to execute and consummate
this Agreement and the transactions contemplated hereby. This Agreement has
been duly executed by the Company and, when delivered in accordance with the
terms hereof, and assuming the valid execution hereof by the Purchaser, will
constitute the valid and binding obligation of the Company enforceable
against the Company in accordance with its terms, except (a) as such
enforceability may be limited by bankruptcy, insolvency, reorganization or
similar laws affecting creditors' rights generally, (b) as enforceability of
any indemnification and contribution provisions may be limited under the
federal and state securities laws and public policy, and (c) that the remedy
of specific performance and injunctive and other forms of equitable relief
may be subject to equitable defenses and to the discretion of the court
before which any proceeding therefor may be brought.

                  (c)  No Conflicts. The execution, delivery and performance
                       ------------
of this Agreement by the Company and the consummation by the Company of the
transactions contemplated hereby does not and will not: (i) conflict with or
violate any provision of the Company's certificate of incorporation or
bylaws (each as amended through the date hereof), or (ii) conflict with, or
constitute a default (or an event which with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
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
which any property or asset of the Company is bound or affected, except
where the failure to do so would not reasonably be expected to have a
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
or stock market to which the Company or the Common Stock is subject, except
where the failure to do so would not reasonably be expected to have a
Material adverse effect on the Company or the transaction contemplated
hereby. There are no notices to or approvals or consents required to be made
by the Company of the NASD, any stock market, the Commission or any other
Person that have not been made and obtained (and any so obtained are in full
force and effect), except where the failure to do so would not reasonably be
expected to have a material adverse effect on the Company or the transaction
contemplated hereby.

                  (d)  Filings, Consents and Approvals. The Company is not
                       -------------------------------
required to obtain any consent, waiver, authorization or order of, give any
notice to, or make any filing or registration with, any court or other
federal, state, local or other governmental authority or other Person in

                  (e)  Issuance of the Shares. The Shares are duly authorized
                       ----------------------

and encumbrances. The Shares have been approved for issuance on and by the
Nasdaq SmallCap Market (subject to official notice of issuance).

Statement (including the information or documents incorporated by reference
therein and all supplements, including the Supplements, and prospectus
thereunder), at the time it was first declared effective, on the date of
this Agreement, and on each Settlement Date, did not, do not and will not
contain any untrue statement of material fact or omit to state any material
fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The Shares are registered under the Securities Act by the

Person, as such fees and expenses are incurred.

                  (i)  Disclosure. Neither the Company nor any other Person
                       ----------
acting on its behalf has provided the Purchaser or its agents or counsel
with any information that constitutes or may, in the Company's opinion,
constitute material non-public information.

                  (j)  SEC Reports; Financial Statements. Except with respect
                       ---------------------------------

                  (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

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

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

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.

                  (h)  Adjustments in Share Numbers and Prices. In the event

entitling the holder thereof to receive directly or indirectly shares of
Common Stock), combination or other similar recapitalization or event

                                 EXHIBIT 'A'

                          TERMS OF INDEMNIFICATION

         (a) INDEMNIFICATION BY THE COMPANY. The Company will indemnify and
             ------------------------------
hold harmless the Purchaser and any Related Persons, 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.
