Statement effective until the expiration of the Effectiveness Period applicable to such
Registration Statement;

the Prospectus included therein (including each preliminary Prospectus) as the Purchaser
reasonably may request to facilitate the public sale or disposition of the Registrable
Securities covered by the Registration Statement;

(d) use its reasonable commercial efforts to register or qualify the Purchaser’s
Registrable Securities covered by such Registration Statement under the securities or “blue
sky” laws of such jurisdictions within the United States as the Purchaser may reasonably

(e) list the Registrable Securities covered by such Registration Statement with any
securities exchange on which the Common Stock of the Company is then listed;

(f) promptly notify the Purchaser at any time when a Prospectus relating thereto is
required to be delivered under the Securities Act, of the happening of any event of which
the Company has knowledge as a result of which the Prospectus contained in such Registration
Statement, as then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing; and

(g) make available for inspection by the Purchaser and any attorney, accountant or
other agent retained by the Purchaser, all publicly available, non-confidential financial
and other records, pertinent corporate documents and properties of the Company, and cause
the Company’s officers, directors and employees to supply all publicly available,
non-confidential information reasonably requested by the attorney, accountant or agent of
the Purchaser.

expenses (including reasonable counsel fees) incurred in connection with complying with state

shall only be responsible for all Registration Expenses.

5. Obligations of Each Holder.

In connection with the registration of Registrable Securities pursuant to a Registration
Statement, each Holder shall:

(a) timely furnish to the Company in writing such information regarding itself and the
intended method of disposition of such Registrable Securities as the Company shall reasonably
request in order to effect the registration thereof;

(b) in the event of an underwritten offering of such Registrable Securities in which such
Holder participates pursuant to Section 8(e) hereof, enter into a customary and reasonable
underwriting agreement and execute such other documents (including without limitation “lock-up” and
indemnity agreements) as the Company and the managing underwriter for such offering may reasonably
request;

(c) notify the Company promptly in the event that any information supplied by such Holder in
writing for inclusion in such Registration Statement or related prospectus is untrue or nor omit to
state a material fact required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they are made, not misleading; immediately discontinue any sale
or other disposition of such Registrable Securities pursuant to such Registration Statement until
the filing of an amendment or supplement to such prospectus as may be necessary so that such
prospectus does not contain an untrue statement of material fact nor omit to state a material fact
required to be stated therein or necessary to make the statements therein, in light of the
circumstances in which they are made, not misleading; and provide the Company with updates on such
information as may be appropriate to make such amendment or supplement effective for such purpose;

(d) comply with the requirements in Section 8(d) of this Agreement.

6. Indemnification.

(a) In the event of a registration of any Registrable Securities under the Securities
Act pursuant to this Agreement, the Company will indemnify and hold harmless the Purchaser,
and its officers, directors and each other person, if any, who controls the Purchaser within
the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint
or several, to which the Purchaser, or such persons may become subject under the Securities
Act or otherwise, insofar as such losses, claims,

 

5

 

damages or liabilities (or actions in respect thereof) arise out of or are based upon
any untrue statement or alleged untrue statement of any material fact contained in any
Registration Statement under which such Registrable Securities were registered under the
Securities Act pursuant to this Agreement, any preliminary Prospectus or final Prospectus
contained therein, or any amendment or supplement thereof, or arise out of or are based upon
the omission or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein, in light of the circurmstances in which
they were made, not misleading, and will reimburse the Purchaser, and each such person for
any reasonable legal or other expenses incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided,
however, that the Company will not be liable in any such case if and to the extent
that any such loss, claim, damage or liability arises out of or is based upon (i) an untrue
statement or alleged untrue statement or omission or alleged omission so made in conformity
with information furnished by or on behalf of the Purchaser or any such in writing
specifically for use in any such document, or (ii) a failure of such person to deliver or
cause to be delivered the final Prospectus contained in the Registration Statement and made
available by the Company.

(b) In the event of a registration of the Registrable Securities under the Securities
Act pursuant to this Agreement, the Purchaser will indemnify and hold harmless the Company,
and its officers, directors and each other person, if any, who controls the Company within
the meaning of the Securities Act, against all losses, claims, damages or liabilities, joint
or several, to which the Company or such persons may become subject under the Securities Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue statement of
any material fact which was furnished in writing by the Purchaser to the Company expressly
for use in (and such information is contained in) the Registration Statement under which
such Registrable Securities were registered under the Securities Act pursuant to this
Agreement, any preliminary Prospectus or final Prospectus contained therein, or any
amendment or supplement thereof, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circurmstances in which they were made, not
misleading, and will reimburse the Company and each such person for any reasonable legal or
other expenses incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action, provided, however, that the Purchaser
will be liable in any such case if and only to the extent that any such loss, claim, damage
or liability arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission so made in conformity with information furnished in writing
to the Company by or on behalf of the Purchaser specifically for use in any such document.
Notwithstanding the provisions of this paragraph, the Purchaser shall not be required to
indemnify any person or entity in excess of the amount of the aggregate net proceeds
received by the Purchaser in respect of Registrable Securities in connection with any such
registration under the Securities Act.

 

6

 

(c) Promptly after receipt by a party entitled to claim indemnification hereunder (an
“Indemnified Party”) of notice of the commencement of any action, such
Indemnified Party shall, if a claim for indemnification in respect thereof is to be
made against a party hereto obligated to indemnify such Indemnified Party (an “Indemnifying
Party”), notify the Indemnifying Party in writing thereof, but the omission so to notify the
Indemnifying Party shall not relieve it from any liability which it may have to such
Indemnified Party other than under this Section 6(c) and shall only relieve it from any
liability which it may have to such Indemnified Party under this Section 6(c) if and to the
extent the Indemnifying Party is prejudiced by such omission. In case any such action shall
be brought against any Indemnified Party and it shall notify the Indemnifying Party of the
commencement thereof, the Indemnifying Party shall be entitled to participate in and, to the
extent it shall wish, to assume and undertake the defense thereof with counsel satisfactory
to such Indemnified Party, and, after notice from the Indemnifying Party to such Indemnified
Party of its election so to assume and undertake the defense thereof, the Indemnifying Party
shall not be liable to such Indemnified Party under this Section 6(c) for any legal expenses
subsequently incurred by such Indemnified Party in connection with the defense thereof; if
the Indemnified Party retains its own counsel, then the Indemnified Party shall pay all
fees, costs and expenses of such counsel, provided, however, that, if the
defendants in any such action include both the Indemnified Party and the Indemnifying Party
and the Indemnified Party shall have reasonably concluded that there may be reasonable
defenses available to it which are different from or additional to those available to the
Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to
conflict with the interests of the Indemnifying Party, the Indemnified Party shall have the
right to select one separate counsel and to assume such legal defenses and otherwise to
participate in the defense of such action, with the reasonable expenses and fees of such
separate counsel and other expenses related to such participation to be reimbursed by the
Indemnifying Party as incurred.

(d) In order to provide for just and equitable contribution in the event of joint
liability under the Securities Act in any case in which either (i) the Purchaser, or any
officer, director or controlling person of the Purchaser, makes a claim for indemnification
pursuant to this Section 6 but it is judicially determined (by the entry of a final judgment
or decree by a court of competent jurisdiction and the expiration of time to appeal or the
denial of the last right of appeal) that such indemnification may not be enforced in such
case notwithstanding the fact that this Section 6 provides for indemnification in such case,
or (ii) contribution under the Securities Act may be required on the part of the Purchaser
or such officer, director or controlling person of the Purchaser in circumstances for which
indemnification is provided under this Section 6; then, and in each such case, the Company
and the Purchaser will contribute to the aggregate losses, claims, damages or liabilities to
which they may be subject (after contribution from others) in such proportion so that the
Purchaser is responsible only for the portion represented by the percentage that the public
offering price of its securities offered by the Registration Statement bears to the public
offering price of all securities offered by such Registration Statement, provided,
however, that, in any such case, (A) the Purchaser will not be required to
contribute any amount in excess of the public offering price of all such securities offered
by it pursuant to such Registration Statement; and (B) no person or entity guilty of
fraudulent misrepresentation (within the meaning of Section 10(f) of the Act) will be
entitled to contribution from any person or entity who was not guilty of such fraudulent
misrepresentation.

7. Representations and Warranties.

(a) The Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange
Act and, except with respect to certain matters which the Company has disclosed to the
Purchaser on Schedule 7, the Company has timely filed all proxy statements, reports,
schedules, forms, statements and other documents required to be filed by it under the
Exchange Act. The Company has filed (i) its Annual Report on Form 10-K for its fiscal year
ended December 31, 2006 and (ii) its Quarterly Report on Form 10-Q for the fiscal quarters
ended March 31, 2007 and June 30, 2007 (collectively, the “SEC Reports”). Each SEC Report
was, at the time of its filing, in substantial compliance with the requirements of its
respective form and none of the SEC Reports, nor the financial statements (and the notes
thereto) included in the SEC Reports, as of their respective filing dates, contained any
untrue statement of a material fact or omitted to state a 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 financial statements of the Company
included in the SEC Reports comply as to form in all material respects with applicable
accounting requirements and the published rules and regulations of the Commission or other
applicable rules and regulations with respect thereto. Such financial statements have been
prepared in accordance with generally accepted accounting principles (“GAAP”) applied on a
consistent basis during the periods involved (except (i) as may be otherwise indicated in
such financial statements or the notes thereto or (ii) in the case of unaudited interim
statements, to the extent they may not include footnotes or may be condensed) and fairly
present in all material respects the financial condition, the results of operations and the
cash flows of the Company and its subsidiaries, on a consolidated basis, as of, and for, the
periods presented in each such SEC Report.

(b) The Common Stock is listed or quoted, as applicable, for trading on the American
Stock Exchange and satisfies all requirements for the continuation of such listing or
quotation, as applicable, and the Company shall do all things necessary for the continuation
of such listing or quotation, as applicable. The Company has not received any notice that
its Common Stock will be delisted from or no longer be quoted on, as applicable, the
American Stock Exchange (except for prior notices which have been fully remedied) or that
the Common Stock does not meet all requirements for the continuation of such listing or
quotation, as applicable.

(c) Neither the Company, nor any of its affiliates, nor any person acting on its or
their behalf, has directly or indirectly made any offers or sales of any security or
solicited any offers to buy any security under circumstances that would cause the offering
of the Securities pursuant to the Security Agreement to be integrated with prior offerings
by the Company for purposes of the Securities Act which would prevent the Company from
selling the Common Stock pursuant to Rule 506 under the Securities Act, or any applicable
exchange-related stockholder approval provisions, nor will the Company or any of its
affiliates or subsidiaries take any action or steps that would cause the offering of the
Securities to be integrated with other offerings.

 

8

 

(d) The Warrants and the shares of Common Stock which the Purchaser may acquire
pursuant to the Warrants are all restricted securities under the Securities Act as of the
date of this Agreement. The Company will not issue any stop transfer order or other order
impeding the sale and delivery of any of the Registrable Securities at such time as such
Registrable Securities are registered for public sale or an exemption from registration is
available, except as required by federal or state securities laws.

(e) The Company understands the nature of the Registrable Securities issuable upon
exercise of the Warrant and recognizes that the issuance of such Registrable Securities may
have a potential dilutive effect. The Company specifically acknowledges that its obligation
to issue the Registrable Securities is binding upon the Company and enforceable regardless
of the dilution such issuance may have on the ownership interests of other shareholders of
the Company.

(f) Except for agreements made in the ordinary course of business, there is no
agreement that has not been filed with the Commission as an exhibit to a registration
statement or to a form required to be filed by the Company under the Exchange Act, the
breach of which could reasonably be expected to have a material and adverse effect on the
Company and its subsidiaries, or would prohibit or otherwise interfere with the ability of
the Company to enter into and perform any of its obligations under this Agreement in any
material respect.

(g) The Company will at all times have authorized and reserved a sufficient number of
 shares of Common Stock for the full exercise of the Warrants.

(h) The Company shall provide written notice to each Holder of (i) the occurrence of
each Discontinuation Event (as defined below) and (ii) the declaration of effectiveness by
the SEC of each Registration Statement required to be filed hereunder, in each case within
three (3) business days of the date of each such occurrence and/or declaration.

8. Miscellaneous.

(a) Remedies. In the event of a breach by the Company or by a Holder, of any of their
respective obligations under this Agreement, each Holder or the Company, as the case may be,
in addition to being entitled to exercise all rights granted by law and under this Agreement
will be entitled to specific performance of its rights under this Agreement. The failure of
the Company to cause each Registration Statement to become effective and to remain effective
as provided herein shall not convey to the Holder(s) any rights to the recovery of monetary
and or liquidated damages.

(b) No Piggyback on Registrations. Except as and to the extent specified in Schedule
7(b) hereto, neither the Company nor any of its security holders (other than the Holders in
such capacity pursuant hereto) may include securities of the Company in any Registration
Statement other than the Registrable Securities, and the Company shall not after the date
hereof enter into any agreement providing any such right for inclusion of shares in the
Registration Statement to any of its security holders. Except as and to the
extent specified in Schedule 7(b) hereto, the Company has not previously entered into
any agreement granting any registration rights with respect to any of its securities to any
person or entity that have not been fully satisfied.

 

9

 

(c) Compliance. Each Holder covenants and agrees that it will comply with the
prospectus delivery requirements of the Securities Act as applicable to it in connection
with sales of Registrable Securities pursuant to the Registration Statement.

(d) Discontinued Disposition. Each Holder agrees by its acquisition of such
Registrable Securities that, upon receipt of a notice from the Company of the occurrence of
a Discontinuation Event (as defined below), such Holder will forthwith discontinue
disposition of such Registrable Securities under the applicable Registration Statement until
such Holder’s receipt of the copies of the supplemented Prospectus and/or amended
Registration Statement or until it is advised in writing (the “Advice”) by the Company that
the use of the applicable Prospectus may be resumed, and, in either case, has received
copies of any additional or supplemental filings that are incorporated or deemed to be
incorporated by reference in such Prospectus or Registration Statement. The Company may
provide appropriate stop orders to enforce the provisions of this paragraph. For purposes
of this Agreement, a “Discontinuation Event” shall mean (i) when the Commission notifies the
Company whether there will be a “review” of such Registration Statement and whenever the
Commission comments in writing on such Registration Statement (the Company shall provide
true and complete copies thereof and all written responses thereto to each of the Holders);
(ii) any request by the Commission or any other Federal or state governmental authority for
amendments or supplements to such Registration Statement or Prospectus or for additional
information; (iii) the issuance by the Commission of any stop order suspending the
effectiveness of such Registration Statement covering any or all of the Registrable
Securities or the initiation of any Proceedings for that purpose; (iv) the receipt by the
Company of any notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any jurisdiction, or the
initiation or threatening of any Proceeding for such purpose; and/or (v) the occurrence of
any event or passage of time that makes the financial statements included in such
Registration Statement ineligible for inclusion therein or any statement made in such
Registration Statement or Prospectus or any document incorporated or deemed to be
incorporated therein by reference untrue in any material respect or that requires any
revisions to such Registration Statement, Prospectus or other documents so that, in the case
of such Registration Statement or Prospectus, as the case may be, it will not contain any
untrue statement of a 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.

(e) Piggy-Back Registrations. If at any time during the applicable Effectiveness
Period there is not an effective Registration Statement covering all of the Registrable
Securities required to be covered during such Effectiveness Period and the Company shall
determine to prepare and file with the Commission a registration statement relating to an
offering for its own account or the account of others under the Securities Act of any of its
equity securities, other than on Form S-4 or Form S-8 (each as

 

10

 

promulgated under the Securities Act) or their then equivalents relating to equity
securities to be issued solely in connection with any acquisition of any entity or business
or equity securities issuable in connection with stock option or other employee benefit
plans, then the Company shall send to each Holder written notice of such determination and,
if within ten (10) days after receipt of such notice, any such Holder shall so request in
writing, the Company shall use its commecially reasonable efforts to include in such
registration statement all or any part of such Registrable Securities such Holder requests
to be registered to the extent the Company may do so without violating registration rights
of others which exist as of the date of this Agreement, subject to customary underwriter
cutbacks applicable to all holders of registration rights and subject to obtaining any
required consent of any selling stockholder(s) to such inclusion under such registration
statement.

If, in connection with any underwritten public offering for the account of the Company
or for stockholders of the Company that have contractual rights to require the Company to
register shares of Common Stock, the managing underwriter(s) thereof shall impose a
limitation on the number of shares of Common Stock which may be included in a registration
statement because, in the judgment of such underwriter(s), marketing or other factors
dictate such limitation is necessary to facilitate such offering, then the Company shall be
obligated to include in the registration statement only such limited portion of the
Registrable Securities with respect to which each Holder has requested inclusion hereunder
as such underwriter(s) shall permit. Any exclusion of Registrable Securities shall be made
pro rata among the Holders seeking to include Registrable Securities in a registration
statement, in proportion to the number of Registrable Securities sought to be included by
such Holders; provided, however, that the Company shall not exclude any Registrable
Securities unless the Company has first excluded all outstanding securities, the holders of
which are not entitled to inclusion of such securities in the registration statement or are
not entitled to pro rata inclusion with the Registrable Securities; and provided, further,
that, after giving effect to the immediately preceding proviso, any exclusion of Registrable
Securities shall be made pro rata with holders of other securities having the right to
include such securities in the registration statement.

(f) Amendments and Waivers. The provisions of this Agreement, including the provisions
of this sentence, may not be amended, modified or supplemented, and waivers or consents to
departures from the provisions hereof may not be given, unless the same shall be in writing
and signed by the Company and the Holders of the then outstanding Registrable Securities.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with
respect to a matter that relates exclusively to the rights of certain Holders and that does
not directly or indirectly affect the rights of other Holders may be given by Holders of at
least a majority of the Registrable Securities to which such waiver or consent relates;
provided, however, that the provisions of this sentence may not be amended,
modified, or supplemented except in accordance with the provisions of the immediately
preceding sentence.

(g) Notices. Any notice or request hereunder may be given to the Company or the
Purchaser at the respective addresses set forth below or as may hereafter be specified in a
notice designated as a change of address under this Section 8(g). Any

	No.                     
	 	Issue Date: August 31, 2007

DIGITAL ANGEL CORPORATION, a corporation organized under the laws of the State of Delaware
(the “Company”), hereby certifies that, for value received, KALLINA CORPORATION, or assigns (the
“Holder”), is entitled, subject to the terms set forth below, to purchase from the Company (as
defined herein) 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 the close of business August 31, 2014 (the “Expiration
Date”), up to 967,742 fully paid and nonassessable shares of Common Stock (as hereinafter defined),
$0.005 par value per share, at the applicable Exercise Price per share (as defined below). The

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 “Common Stock” includes (i) the Company’s Common Stock, par value $0.005
per share; and (ii) any other securities into which or for which any of the securities
described in the preceding clause (i) may be converted or exchanged pursuant to a plan of
recapitalization, reorganization, merger, sale of assets or otherwise.

(b) The term “Company” shall include Digital Angel Corporation and any person or entity
which shall succeed, or assume the obligations of, Digital Angel Corporation hereunder.

(c) The “Exercise Price” applicable under this Warrant shall be a price of $1.69 for
all shares acquired hereunder;

 

 

 

(d) 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.

(e) The term “Security Agreement” means the Security Agreement dated as of the date
hereof among the Holder, the Company and various Subsidiaries of the Company party thereto,
as amended, modified, restated and/or supplemented from time to time.

1. Exercise of Warrant.

1.1 Number of Shares Issuable upon Exercise. From and after the date hereof 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 an exercise notice in the
form 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. For purposes hereof, the “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 the American Stock Exchange or another
national exchange or is quoted on the National or Capital 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 the American Stock Exchange or
another national exchange or on the Nasdaq but is traded on the NASD Over The Counter
Bulletin Board, 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

 

1.3 Company Acknowledgment. The Company will, at the time of the exercise of this
Warrant, upon the request of the holder hereof acknowledge in writing its continuing obligation to
afford to such holder any rights to which such holder shall continue to be entitled after such
exercise in accordance with the provisions of this Warrant. If the holder shall fail to make any
such request, such failure shall not affect the continuing obligation of the Company to afford to
such holder any such rights.

1.4 Trustee for Warrant Holders. In the event that a bank or trust company shall have
been appointed as trustee for the holders of this Warrant pursuant to Subsection 3.2, such bank or
trust company shall have all the powers and duties of a warrant agent (as hereinafter described)
and shall accept, in its own name for the account of the Company or such successor person as may be
entitled thereto, all amounts otherwise payable to the Company or such successor, as the case may
be, on exercise of this Warrant pursuant to this Section 1.

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 in accordance herewith. As
soon as practicable after the exercise of this Warrant in full or in part, and in any event within
three (3) business 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 Exercise.

(a) Payment may be made either (i) in cash by wire transfer of immediately available
funds 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 this Warrant, or shares of
Common Stock and/or Common Stock receivable upon exercise of this Warrant in accordance with
the formula set forth in subsection (b) below, or (iii) by a combination of any of the
foregoing methods, for the number of Common Shares specified in such Exercise Notice (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.

 

3

 

(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 this Warrant or, if
only a portion of this Warrant is being exercised, the portion of this 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 =	 	the Exercise Price per share (as adjusted to the date of such calculation)

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

3.1 Reorganization, Consolidation, Merger, Etc. If there occurs (i) any capital
reorganization or any reclassification of the Common Stock of the Company; (ii) any consolidation
or merger of the Company with or into another person (A) where the Company is not the continuing
entity, (B) which results in any reorganization or reclassification of its outstanding Common
Stock; or (C) which results in the Common Stock of the Company being changed into or exchanged for
common stock or other securities of any other entity or cash or any other assets, or (iii) the sale
or conveyance of all or substantially all of the assets of the Company to another person, then, as
a condition precedent to any such reorganization, reclassification, consolidation, merger, sale or
conveyance, proper and adequate provision shall be made by the Company whereby the Holder will be
entitled to receive upon surrender of the Warrant to the Company (x) to the extent there are cash
proceeds resulting from the consummation of such reorganization, reclassification, consolidation,
merger, sale or conveyance, in exchange for such Warrant, cash in an amount equal to the cash
proceeds that would have been payable to the Holder had the Holder exercised such Warrant
immediately prior to the consummation of such reorganization, reclassification, consolidation,
merger, sale or conveyance, less the aggregate Exercise Price payable upon exercise of the Warrant,
and (y) to the extent that the Holder would be entitled to receive Common Stock (or Other
Securities) (in addition to or in lieu of cash in connection with any such reorganization,
reclassification, consolidation, merger, sale or conveyance), the same kind and amounts of
securities or other

 

4

 

assets, or both, that are issuable or distributable to the holders of outstanding Common Stock
(or Other Securities) of the Company with respect to their Common Stock (or Other Securities) upon
such reorganization, reclassification, consolidation, merger, sale or conveyance, as would have
been deliverable to the Holder had the Holder exercised such Warrant immediately prior to the
consummation of such reorganization, reclassification, consolidation, merger, sale or conveyance
less an amount of such securities having a value equal to the aggregate Exercise Price payable upon
exercise of the Warrant. The Company shall provide the Holder notice of its intent to affect
such reorganization, reclassification, consolidation, merger, sale or conveyance promptly after
such notice is mailed or otherwise provided to the holders of the Common Stock, but in no event
less than fifteen (15) days prior to the consummation of such transaction. If Holder elects to
exercise this Warrant in connection with the consummation of such transaction, Holder shall
promptly notify the Company, provided, however, that such notification shall in no case be provided
less than five (5) days prior to the scheduled consummation or effective date, as the case may be,
of the transaction. If the Holder does not choose to exercise this Warrant at the time such
reorganization, reclassification, consolidation, merger, sale or conveyance, then this Warrant
shall continue in full force pursuant to Section 3.3 below.

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, concurrently with
any distributions made to holders of its Common Stock, shall at its expense deliver or cause to be
delivered to the Holder the stock and other securities and property (including cash, where
applicable) receivable by the Holder pursuant to Section 3.1, or, if the Holder shall so instruct
the Company, to a bank or trust company specified by the Holder and having its principal office in
New York, NY as trustee for the Holder.

3.3 Continuation of Terms. Upon any reorganization, consolidation, merger or transfer
(and any dissolution following any transfer) referred to in this Section 3, so long as a portion of
this Warrant remains unexercised, this Warrantshall 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. The Holder of this Warrant, on exercise hereof at any time after the consummation or
effective date of any reorganization, consolidation, merger or transfer, shall receive, in lieu of
the Common Stock issuable on such exercise prior to the date of such Reorganization, the stock and
other securities and property (including cash) to which such holder would have been entitled upon
the date of such transaction if such holder had exercised this Warrant immediately prior thereto
less an amount of cash and/or securities having a value equal to the aggregate Exercise Price
payable upon exercise of the Warrant. 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 the Company’s
securities and property (including cash, where applicable) receivable by the Holder will be
delivered to the Holder or the Trustee as contemplated by Section 3.2.

 

5

 

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 or any preferred stock issued by the Company, (b) subdivide its outstanding shares of
Common Stock, (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 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 shall thereafter, on the exercise hereof as provided in
Section 1, be entitled to receive shall be adjusted 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 (taking into account the provisions of this
Section 4). Notwithstanding the foregoing, in no event shall the Exercise Price be less than the
par value of the Common Stock.

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 this 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 this 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 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 this
Warrant, shares of Common Stock (or Other Securities) from time to time issuable on the exercise of
this 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”) in whole or in part. 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

 

6

 

Company demonstrating compliance with applicable securities laws, which shall include, without
limitation, a legal opinion from the Transferor’s counsel (at the Company’s expense) 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 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 Holder dated as of the date hereof, as the same may be amended, modified
and/or supplemented from time to time.

10. Maximum Exercise. Notwithstanding anything herein to the contrary, in no event
shall the Holder be entitled to exercise any portion of this Warrant in excess of that portion of
this Warrant upon exercise of which the sum of (1) the number of shares of Common Stock
beneficially owned by the Holder and its Affiliates (other than shares of Common Stock which may be
deemed beneficially owned through the ownership of the unexercised portion of this Warrant or the
unexercised or unconverted portion of any other security of the Holder subject to a limitation on
conversion analogous to the limitations contained herein) and (2) the number of shares of Common
Stock issuable upon the exercise of the portion of this Warrant with respect to which the
determination of this proviso is being made, would result in beneficial ownership by the Holder and
its Affiliates of any amount greater than 9.99% of the then outstanding shares of Common Stock
(whether or not, at the time of such exercise, the Holder and its Affiliates beneficially own more
than 9.99% of the then outstanding shares of Common Stock). As used herein, the term “Affiliate”
means any person or entity that, directly or indirectly through one or more intermediaries,
controls or is controlled by or is under common control with a person or entity, as such terms are
used in and construed under Rule 144 under the Securities Act. For purposes of the second
preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of
the Securities Exchange Act of 1934, as amended, and Regulations 13D-G thereunder, except as
otherwise provided in clause (1) of such sentence. For any reason at any time, upon written or
oral request of the Holder, the Company shall within three (3) business days confirm orally and in
writing to the Holder the number of shares of Common Stock outstanding as of any given date. The
limitations set forth herein (x) may be waived by the Holder upon provision of no less than
sixty-one (61) days prior written notice to the Company and (y) shall automatically become null and
void following notice to the Company upon the occurrence and during the continuance of an Event of
Default (as defined in the

 

7

 

Security Agreement), except that at no time shall the Company be obligated to issue any shares
of Common Stock pursuant to the terms of this Warrant, the Purchase Agreement, any Related
Agreement (as defined in the Purchase Agreement) if the issuance of such shares of Common Stock
would exceed the aggregate number of shares of Common Stock which the Company may issue pursuant to
the terms of this Warrant, the Purchase Agreement or any Related Agreement without violating the
rules or regulations of the Principal Market (the “Exchange Cap”), except that such limitation
shall not apply in the event that the Company obtains the approval of its stockholders as required
by the applicable rules or regulations of the Principal Market for issuances of Common Stock in
excess of such amount. Notwithstanding anything contained herein to the contrary, the number of
shares of Common Stock issuable by the Company and acquirable by the Holder pursuant to the terms
of this Warrant, the Purchase Agreement, any Related Agreement (as defined in the Purchase
Agreement) or otherwise, shall not exceed an aggregate of 8,923,813 shares of Common Stock (subject
to appropriate adjustment for stock splits, stock dividends, or other similar recapitalizations
affecting the Common Stock).”

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. Rights of Shareholders. No Holder shall be entitled to vote or receive dividends
or be deemed the holder of the shares of Common Stock or any other securities of the Company which
may at any time be issuable upon exercise of this Warrant for any purpose (the “Warrant Shares”),
nor shall anything contained herein be construed to confer upon the Holder, as such, any of the
rights of a shareholder of the Company or any right to vote for the election of directors or upon
any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon the recapitalization, issuance of shares, reclassification of
shares, change of nominal value, consolidation, merger, conveyance or otherwise) or to receive
notice of meetings, or to receive dividends or subscription rights or otherwise, in each case,
until the earlier to occur of (x) the date of actual delivery to Holder (or its designee) of the
Warrant Shares issuable upon the exercise hereof or (y) the third business day following the date
such Warrant Shares first become deliverable to Holder, as provided herein.

14. Notices, Etc. All notices and other communications from the Company to the Holder
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 who has so
furnished an address to the Company.

 

8

 

15. 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 THE 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 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

the validity or enforceability of any other provision of this Warrant. The headings in this
