COMMON STOCK PURCHASE WARRANT    
    



	No. 2003-1	 	Issue Date: August 28, 2003





        DIGITAL ANGEL CORPORATION, a corporation organized under the laws of the State of Delaware (the "Company"), hereby certifies that, for value received, LAURUS
MASTER FUND, LTD., or its assigns (the "Holder"), is entitled, subject to the terms set forth below, to purchase from the Company from and after the Issue Date of this Warrant and at any time
or from time to time before 5:00 p.m., New York time, through five (5) years after such date (the "Expiration Date"), up to 115,000 fully paid and nonassessable shares of Common Stock
(as hereinafter defined), $.005 par value, of the Company, at the Exercise Price (as defined below). The number and character of such shares of Common Stock and the Exercise Price are subject to
adjustment as provided herein. 


        As
used herein the following terms, unless the context otherwise requires, have the following respective meanings: 


        (a)   The
term "Company" shall include Digital Angel Corporation and any corporation which shall succeed or assume the obligations of Digital Angel Corporation hereunder. 


        (b)   The
term "Common Stock" includes (a) the Company's Common Stock, par value $.005 per share, and (b) any other securities into which or for which any of the
securities described in (a) may be converted or exchanged pursuant to a plan of recapitalization, reorganization, merger, sale of assets or otherwise. 



        (c)   The
term "Other Securities" refers to any stock (other than Common Stock) and other securities of the Company or any other person (corporate or otherwise) which the
holder of the Warrant at any time shall be entitled to receive, or shall have received, on the exercise of the Warrant, in lieu of or in addition to Common Stock, or which at any time shall be
issuable or shall have been issued in exchange for or in replacement of Common Stock or Other Securities pursuant to Section 4 or otherwise. 


        (d)   The
term "Exercise Price" shall be as follows: 



        a.     70,000
shares at $2.55 per share (130% of the average closing price of the Common Stock for the three trading days immediately prior to the date hereof); 


        b.     35,000
shares at $2.75 per share (140% of the average closing price of the Common Stock for the three trading days immediately prior to the date hereof); and 


        c.     10,000
shares at $2.95 per share (150% of the average closing price of the Common Stock for the three trading days immediately prior to the date hereof.) 








 





        1.    Exercise of Warrant.    



        1.1    Number of Shares Issuable upon Exercise.    From and after the date hereof and through and including the
Expiration Date, the Holder shall be entitled to receive, upon exercise of this Warrant in whole or in part, by delivery of an original or fax copy of the exercise notice attached hereto as
Exhibit A (the "Exercise Notice"), shares of Common Stock of the Company, subject to adjustment pursuant to Section 4. 


        1.2    Fair Market Value.    Fair Market Value of a share of Common Stock as of a particular date (the "Determination
Date") shall mean: 



        (a)   If
the Company's Common Stock is traded on an exchange or is quoted on the National or SmallCap Market of The Nasdaq Stock Market, Inc.("Nasdaq"), then the
closing or last sale price, respectively, reported for the last business day immediately preceding the Determination Date. 


        (b)   If
the Company's Common Stock is not traded on an exchange or on the Nasdaq but is traded on the NASD OTC Bulletin Board or BBX Exchange, then the mean of the average of
the closing bid and asked prices reported for the last business day immediately preceding the Determination Date. 


        (c)   Except
as provided in clause (d) below, if the Company's Common Stock is not publicly traded, then as the Holder and the Company agree or in the absence of
agreement by arbitration in accordance with the rules then in effect of the American Arbitration Association, before a single arbitrator to be chosen from a panel of persons qualified by education and
training to pass on the matter to be decided. 


        (d)   If
the Determination Date is the date of a liquidation, dissolution or winding up, or any event deemed to be a liquidation, dissolution or winding up pursuant to the
Company's charter, then all amounts to be payable per share to holders of the Common Stock pursuant to the charter in the event
of such liquidation, dissolution or winding up, plus all other amounts to be payable per share in respect of the Common Stock in liquidation under the charter, assuming for the purposes of this
clause (d) that all of the shares of Common Stock then issuable upon exercise of the Warrant are outstanding at the Determination Date. 





        2.    Procedure for Exercise.    



        2.1    Delivery of Stock Certificates, etc. on Exercise.    The Company agrees that the shares of Common Stock
purchased upon exercise of this Warrant shall be deemed to be issued to the Holder as the record owner of such shares as of the close of business on the date on which this Warrant shall have been
surrendered and payment made for such shares as aforesaid. As soon as practicable after the exercise of this Warrant in whole or in part, and in any event within three (3) trading days
thereafter, the Company at its expense (including the payment by it of any applicable issue taxes) will cause to be issued in the name of and delivered to the Holder, or as such Holder (upon payment
by such holder of any applicable transfer taxes) may direct in compliance with applicable securities laws, a certificate or certificates for the number of duly and validly issued, fully paid and
nonassessable shares of Common Stock (or Other Securities) to which such Holder shall be entitled on such exercise, plus, in lieu of any fractional share to which such holder would otherwise be
entitled, cash equal to such fraction multiplied by the then Fair Market Value of one full share, together with any other stock or other securities and property (including cash, where applicable) to
which such Holder is entitled upon such exercise pursuant to Section 1 or otherwise. 



2







 

        2.2    Exercise.    



        (a)   Payment
may be made either (i) in cash or by certified or official bank check payable to the order of the Company equal to the applicable aggregate Exercise
Price, (ii) by delivery of the Warrant, Common Stock and/or Common Stock receivable upon exercise of the Warrant in accordance with Section (b) below, or (iii) by a combination of
any of the foregoing methods, for the number of Common Shares specified in such form (as such exercise number shall be adjusted to reflect any adjustment in the total number of shares of Common Stock
issuable to the holder per the terms of this Warrant), and the Holder shall thereupon be entitled to receive the number of duly authorized, validly issued, fully-paid and
non-assessable shares of Common Stock (or Other Securities) determined as provided herein. 



        (b)   Notwithstanding
any provisions herein to the contrary, if the Fair Market Value of one share of Common Stock is greater than the Exercise Price (at the date of
calculation as set forth below), in lieu of exercising this Warrant for cash, the Holder may elect to receive shares equal to the value (as determined below) of this Warrant (or the portion thereof
being exercised) by surrender of this Warrant at the principal office of the Company together with the properly endorsed Exercise Notice in
which event the Company shall issue to the Holder a number of shares of Common Stock computed using the following formula: 




	            	 	 	 	X=Y (A-B)

            A
	 	 	 	 	

	

 	
 	

Where	
 	

X=	
 	

the number of shares of Common Stock to be issued to the Holder
	

 	
 	

 	
 	

Y=	
 	

the number of shares of Common Stock purchasable under the Warrant or, if only a portion of the Warrant is being exercised, the portion of the Warrant being exercised (at the date of such calculation)
	

 	
 	

 	
 	

A=	
 	

the Fair Market Value of one share of the Company's Common Stock (at the date of such calculation)
	

 	
 	

 	
 	

B=	
 	

Exercise Price (as adjusted to the date of such calculation)





        3.    Effect of Reorganization, etc.; Adjustment of Exercise
Price.    



        3.1    Reorganization, Consolidation, Merger, etc.    In case at any time or from time to time, the Company shall
(a) effect a reorganization, (b) consolidate with or merge into any other person, or (c) transfer all or substantially all of its properties or assets to any other person under
any plan or arrangement contemplating the dissolution of the Company, then, in each such case, as a condition to the consummation of such a transaction, proper and adequate provision shall be made by
the Company whereby the Holder of this Warrant, on the exercise hereof as provided in Section 1 at any time after the consummation of such reorganization, consolidation or merger or the
effective date of such dissolution, as the case may be, shall receive, in lieu of the Common Stock (or Other Securities) issuable on such exercise prior to such consummation or such effective date,
the stock and other securities and property (including cash) to which such Holder would have been entitled upon such consummation or in connection with such dissolution, as the case may be, if such
Holder had so exercised this Warrant immediately prior thereto, all subject to further adjustment thereafter as provided in Section 4. 



        3.2    Dissolution.    In the event of any dissolution of the Company following the transfer of all or substantially
all of its properties or assets, the Company, prior to such dissolution, shall at its expense deliver or cause to be delivered the stock and other securities and property (including cash, where
applicable) receivable by the Holder of the Warrant after the effective date of such 



3







 




dissolution
pursuant to Section 3.1 to a bank or trust company having its principal office in New York, NY, as trustee for the Holder of the Warrant. 



        3.3    Continuation of Terms.    Upon any reorganization, consolidation, merger or transfer (and any dissolution
following any transfer) referred to in this Section 3, this Warrant shall continue in full force and effect and the terms hereof shall be applicable to the shares of stock and other securities
and property receivable on the exercise of this Warrant after the consummation of such reorganization, consolidation or merger or the effective date of dissolution following any such transfer, as the
case may be, and shall be binding upon the issuer of any such stock or other securities, including, in the case of any such transfer, the person acquiring all or substantially all of the properties or
assets of the Company, whether or not such person shall have expressly assumed the terms of this Warrant as provided in Section 4. In the event this Warrant does not continue in full force and
effect after the consummation of the transactions described in this Section 3, then only in such event will the Company's securities and property (including cash, where applicable) receivable
by the holders of the Warrant be delivered to the Trustee as contemplated by Section 3.2. 




        4.    Extraordinary Events Regarding Common Stock.    In the event that the Company shall
(a) issue additional shares of the Common Stock as a dividend or other distribution on outstanding Common Stock, (b) subdivide its outstanding shares of Common Stock, or
(c) combine its outstanding shares of the Common Stock into a smaller number of shares of the Common Stock, then, in each such event, the Exercise Price shall, simultaneously with the happening
of such event, be adjusted by multiplying the then current Exercise Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such
event and the denominator of which shall be the number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the Exercise Price then in
effect. The Exercise Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described herein in this Section 4. The number of shares
of Common Stock that the holder of this Warrant shall thereafter, on the exercise hereof as provided in Section 1, be entitled to receive shall be increased to a number determined by
multiplying the number of shares of Common Stock that would otherwise (but for the provisions of this Section 4) be issuable on such exercise by a fraction of which (a) the numerator is
the Exercise Price that would otherwise (but for the provisions of this Section 4) be in effect, and (b) the denominator is the Exercise Price in effect on the date of such exercise. 


        5.    Certificate as to Adjustments.    In each case of any adjustment or readjustment in the
shares of Common Stock (or Other Securities) issuable on the exercise of the Warrant, the Company at its expense will promptly cause its Chief Financial Officer or other appropriate designee to
compute such adjustment or readjustment in accordance with the terms of the Warrant and prepare a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based, including a statement of (a) the consideration received or
receivable by the Company for any additional shares of Common Stock (or Other Securities) issued or sold or deemed to have been issued or sold, (b) the number of shares of Common Stock (or
Other Securities) outstanding or deemed to be outstanding, and (c) the Exercise Price and the number of shares of Common Stock to be received upon exercise of this Warrant, in effect
immediately prior to such adjustment or readjustment and as adjusted or readjusted as provided in this Warrant. The Company will forthwith mail a copy of each such certificate to the holder of the
Warrant and any Warrant agent of the Company (appointed pursuant to Section 11 hereof). 



        6.    Reservation of Stock, etc. Issuable on Exercise of Warrant.    The Company will at all
times reserve and keep available, solely for issuance and delivery on the exercise of the Warrant, shares of Common Stock (or Other Securities) from time to time issuable on the exercise of the
Warrant.

        7.    Assignment; Exchange of Warrant.    Subject to compliance with applicable securities
laws, this Warrant, and the rights evidenced hereby, may be transferred by any registered holder hereof (a "Transferor") with respect to any or all of the Shares. On the surrender for exchange of this
Warrant, with the Transferor's endorsement in the form of Exhibit B attached hereto (the "Transferor Endorsement Form") and together with evidence reasonably satisfactory to the Company
demonstrating compliance with applicable securities laws, which shall include, without limitation, a legal opinion from the Transferor's counsel that such transfer is exempt from the registration
requirements of applicable securities laws, the Company at its expense (but with payment by the Transferor of any applicable transfer taxes) will issue and deliver to or on the order of the Transferor
thereof a new Warrant of like tenor, in the name of the Transferor and/or the transferee(s) specified in such Transferor Endorsement Form (each a "Transferee"), calling in the aggregate on the face or
faces thereof for the number of shares of Common Stock called for on the face or faces of the Warrant so surrendered by the Transferor. 


        8.    Replacement of Warrant.    On receipt of evidence reasonably satisfactory to the Company
of the loss, theft, destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement or security reasonably
satisfactory in form and amount to the Company or, in the case of any such mutilation, on surrender and cancellation of this Warrant, the Company at its expense will execute and deliver, in lieu
thereof, a new Warrant of like tenor. 


        9.    Registration Rights.    The Holder of this Warrant has been granted certain registration
rights by the Company. These registration rights are set forth in a Registration Rights Agreement entered into by the Company and Purchaser at or prior to the issue date of this Warrant. 


        10.    Maximum Exercise.    The Holder shall not be entitled to exercise this Warrant on an
exercise date, in connection with that number of shares of Common Stock which would be in excess of the sum of (i) the
number of shares of Common Stock beneficially owned by the Holder and its affiliates on an exercise date, and (ii) the number of shares of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this proviso is being made on an exercise date, which would result in beneficial ownership by the Holder and its affiliates of more than 4.99% of the
outstanding shares of Common Stock of the Company on such date. For the purposes of the proviso to the immediately preceding sentence, beneficial ownership shall be determined in accordance with
Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder. Notwithstanding the foregoing, the restriction described in this paragraph
may be revoked upon seventy -five (75) calendar days' prior notice from the Holder to the Company and is automatically null and void
upon an Event of Default under the Note. 


        11.    Warrant Agent.    The Company may, by written notice to the each holder of the Warrant,
appoint an agent for the purpose of issuing Common Stock (or Other Securities) on the exercise of this Warrant pursuant to Section 1, exchanging this Warrant pursuant to Section 7, and
replacing this Warrant pursuant to Section 8, or any of the foregoing, and thereafter any such issuance, exchange or replacement, as the case may be, shall be made at such office by such agent. 



        12.    Transfer on the Company's Books.    Until this Warrant is transferred on the books of
the Company, the Company may treat the registered holder hereof as the absolute owner hereof for all purposes, notwithstanding any notice to the contrary. 


        13.    Notices, etc.    All notices and other communications from the Company to the Holder of
this Warrant shall be mailed by first class registered or certified mail, postage prepaid, at such address as may have been furnished to the Company in writing by such holder or, until any such Holder
furnishes to the Company an address, then to, and at the address of, the last Holder of this Warrant who has so furnished an address to the Company. 


5







 



        14.    Voluntary Adjustment by the Company.    The Company may at any time during the term of
this Warrant reduce the then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company. 



        15.    Governing Law. THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED IN SUCH STATE WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS THEREOF. COMPANY HEREBY CONSENTS AND AGREES THAT THE STATE
OR FEDERAL COURTS LOCATED IN THE COUNTY OF NEW YORK, STATE OF NEW YORK SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN COMPANY AND HOLDER PERTAINING TO THIS
WARRANT OR AS TO ANY MATTER ARISING OUT OF OR RELATED TO THIS WARRANT; PROVIDED, THAT HOLDER AND COMPANY ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS
MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF THE COUNTY OF NEW YORK, STATE OF NEW YORK; AND FURTHER PROVIDED, THAT NOTHING IN THIS AGREEMENT SHALL
BE DEEMED OR OPERATE TO PRECLUDE HOLDER FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO COLLECT THE OBLIGATIONS, TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR THE
OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF HOLDER. COMPANY EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT,
AND COMPANY HEREBY WAIVES ANY OBJECTION WHICH IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON
CONVENIENS.    COMPANY HEREBY WAIVES PERSONAL SERVICE OF THE SUMMONS, COMPLAINT AND OTHER PROCESS ISSUED IN ANY SUCH ACTION OR SUIT AND AGREES THAT SERVICE OF SUCH
SUMMONS, COMPLAINT AND OTHER PROCESS MAY BE MADE BY REGISTERED OR CERTIFIED MAIL, ADDRESSED TO COMPANY, AND THAT SERVICE SO MADE SHALL BE DEEMED COMPLETED UPON THE EARLIER OF COMPANY'S ACTUAL RECEIPT
THEREOF OR THREE (3) DAYS AFTER DEPOSIT IN THE U.S. MAILS, PROPER POSTAGE PREPAID. THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO
ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY
DISPUTE, WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE BETWEEN HOLDER AND COMPANY ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION
WITH THIS WARRANT OR THE TRANSACTIONS RELATED THERETO. THE PREVAILING PARTY SHALL BE ENTITLED TO RECOVER FROM THE OTHER PARTY ITS REASONABLE ATTORNEY'S FEES AND COSTS. IN THE EVENT THAT ANY PROVISION
OF THIS WARRANT IS INVALID OR UNENFORCEABLE UNDER ANY APPLICABLE STATUTE OR RULE OF LAW, THEN SUCH PROVISION SHALL BE DEEMED INOPERATIVE TO THE EXTENT THAT IT MAY CONFLICT THEREWITH AND SHALL BE
DEEMED MODIFIED TO CONFORM WITH SUCH STATUTE OR RULE OF LAW. ANY SUCH PROVISION WHICH MAY PROVE INVALID OR UNENFORCEABLE UNDER ANY LAW SHALL NOT AFFECT THE VALIDITY OR UNENFORCEABILITY OF ANY OTHER
PROVISION OF THIS NOTE. NOTHING CONTAINED HEREIN SHALL BE DEEMED OR OPERATE TO PRECLUDE HOLDER FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION AGAINST THE COMPANY IN ANY OTHER JURISDICTION TO COLLECT
ON THE COMPANY'S OBLIGATIONS TO HOLDER OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF HOLDER. 


6







 



        16.    Miscellaneous.    This Warrant and any term hereof may be changed, waived, discharged
or terminated only by an instrument in writing signed by the party against which enforcement of such change, waiver, discharge or termination is sought. This Warrant shall be governed by and construed
in accordance with the laws of State of New York without regard to principles of conflicts of laws. Any action brought concerning the transactions contemplated by this Warrant shall be brought only in
the state courts of New York or in the federal courts located in the state of New York; provided, however, that the Holder may choose to waive this provision and bring an action outside the state of
New York. The individuals executing this Warrant on behalf of the Company agree to submit to the jurisdiction of such courts and waive trial by jury. The prevailing party shall be entitled to recover
from the other party its reasonable attorney's fees and costs. In the event that any provision of this Warrant is invalid or unenforceable under any applicable statute or rule of law, then such
provision shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any such provision which may prove invalid
or unenforceable under any law shall not affect the validity or enforceability of any other provision of this Warrant. The headings in this Warrant are for purposes of reference only, and shall not
limit or otherwise affect any of the terms hereof. The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other provision. The Company
acknowledges that legal counsel participated in the preparation of this Warrant and, therefore, stipulates that the rule of construction that ambiguities are to be resolved against the drafting party
shall not be applied in the interpretation of this Warrant to favor any party against the other party.
