Agreements, or which could be expected to result, either individually or in the

Sarbanes-Oxley Act of 2002 and any rules or regulations promulgated thereunder
by the Commission that are applicable to it as of the Effective Date.  The
Company maintains a system of internal accounting controls sufficient to
provide reasonable assurance that (i) transactions are executed in accordance
with management’s general or specific authorizations, (ii) transactions are
recorded as necessary to permit preparation of financial statements in
conformity with GAAP and to maintain asset accountability, (iii) access to
assets is permitted only in accordance with management’s general or specific

with respect to any differences.  The Company has established disclosure

for the Company and designed such disclosure controls and procedures to ensure
that information required to be disclosed by the Company in the reports it
files or submits under the Exchange Act is recorded, processed, summarized and
reported, within the time periods specified in the Commission’s rules and
forms.  The Company’s certifying officers have evaluated the effectiveness
of the Company’s disclosure controls and procedures as of the end of the period
covered by the Company’s most recently filed periodic report under the Exchange
Act (such date, the “Evaluation
Date”) and concluded that such controls were ineffective as of
the Evaluation Date.   The Company presented in its most recently filed
periodic report under the Exchange Act such conclusion of the certifying
officers about the effectiveness of the disclosure controls and procedures
based on their evaluations as of the Evaluation Date.  Since the
Evaluation Date, there have been no changes in the Company’s internal control
over financial reporting (as such term is defined in the Exchange Act) that has
materially affected, or is reasonably likely to materially affect, the Company’s
internal control over financial reporting, and no significant deficiencies or

SECTION 6.         REPRESENTATIONS AND WARRANTIES OF THE HOLDERS

Each Holder, severally and not jointly, hereby
represents and warrants to the Company as of the date hereof and as of each
Closing Date with respect to each purchase of Notes by such Holder as follows
(such representations and warranties do not lessen or obviate the
representations and warranties of the Company set forth in this Agreement):

 12

6.1          Organization; Authority

and in good standing under the laws of the jurisdiction of its organization
with full right, corporate or partnership power and authority to enter into and

otherwise to carry out its obligations hereunder and thereunder.  The
execution, delivery and performance by Holder of the transactions contemplated
by the Transaction Agreements have been duly authorized by all necessary
corporate or similar action on the part of such Holder.  Each Transaction
Agreement to which it is a party has been duly executed by Holder, and when
delivered by Holder in accordance with the terms hereof, will constitute the
valid and legally binding obligation of the Holder, enforceable against it in
accordance with its terms, except (i) as limited by general equitable
principles and applicable bankruptcy, insolvency, reorganization, moratorium
and other laws of general application affecting enforcement of creditors’
rights generally, (ii) as limited by laws relating to the availability of
specific performance, injunctive relief or other equitable remedies and (iii)
insofar as indemnification and contribution provisions may be limited by
applicable law.

6.2          Investment Representations

(a)            Information about the Company.  The Holder has had access to and has been
furnished with information relating to the business, operations and financial

contemplated hereby, and has had an adequate opportunity to ask such questions

Company, regarding the Company and its business to the extent deemed necessary
by the Holder in order to form a decision concerning an investment in the

the Warrant Shares, excepts as provided in Section 8 of this Agreement.  Holder also understands that there is no
assurance that any exemption from registration under the Securities Act will be

transfer all or any portion of the Notes, Warrants or the Warrant Shares under
the circumstances, in the amounts or at the times Holder might propose.

(c)           Acquisition
for Own Account.  Holder is acquiring the Notes and Warrants,
and will acquire the Warrant Shares, for Holder’s own account for investment
only, and not with a view towards their public distribution.

(d)           Holder
Can Protect Its Interest.  Holder represents that by
reason of its, or of its management’s, business or financial experience, Holder
has the capacity to protect its own interests in connection with the transactions
contemplated in this Agreement and the Security Documents.  Further, Holder is aware of no publication of
any advertisement in connection with the transactions contemplated in the
Agreement.

Holder.  Holder represents that it is an accredited
Holder within the meaning of Regulation D of the Securities Act.

SECTION
8.         REGISTRATION RIGHTS

8.1          Registration Rights 

The
Company agrees to prepare and file with the Commission, no later than fifteen
(15) days following the date on which the Company’s Annual Report on Form
10-KSB is due for the fiscal year ending April 30, 2007 (the “Filing Date”), a
registration statement on Form SB-2, Form S-3
or such other form of registration statement as may be required by
the Securities Act or as may be deemed appropriate by the Company (the “Registration Statement”)
to enable the resale of the Warrant Shares underlying the Closing Warrants (the
“Registrable Securities”)
by the Holders from time to time on the OTC Bulletin Board or in
privately-negotiated transactions.  The
term “Registrable Securities” does not include the Warrant Shares underlying
the Initial Interest Warrants or any Quarterly Interest Warrants issued to the
Holders.

8.2          Registration Procedures

The Company will keep each Holder advised in writing as to the status
of the Registration Statement as set forth herein.  At the Company’s expense, the Company will:

(a)         use commercially reasonable efforts to cause
the Registration Statement to be declared effective by the Commission within
forty-five (45) days of the Filing Date (in the case of no review of the
Registration Statement by the Commission) or ninety (90) days of the Filing
Date (in the case of a review of the Registration Statement by the Commission)
(as applicable, the “Required
Effective Date”);

(b)         promptly and without delay prepare and file
with the Commission, and concurrently provide copies to the Holder, such
amendments and supplements to the Registration Statement and the prospectus
used in connection therewith as may be necessary to keep the Registration
Statement current, effective and free from any material misstatement or
omission to state a material fact for a period not exceeding, with respect to
each Holder’s Registrable Securities, the earlier of the (i) second anniversary
of the effective date of the Registration Statement, (ii) the date on which the
Holder may sell all Registrable Securities then held by the Holder without
restriction by the volume limitations of Rule 144(e) of the Securities Act, or
(iii) such time as all Registrable Securities have been sold pursuant to a
Registration Statement;

(c)         furnish such number of prospectuses and
other documents incident to such prospectus, including any prospectus amendment
or prospectus supplement, as a Holder from time to time may reasonably request;

(d)         use commercially reasonable efforts to
register and qualify the Registrable Securities under such other securities or
blue sky laws of such jurisdictions as will be reasonably requested by the Holders;
provided, that the Company will not be required, in connection with any such
registration and qualification or as a condition to any such registration and
qualification, to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions;

 15
 

(e)         notify each Holder of Registrable Securities
covered by such Registration Statement at any time when a prospectus relating
to such Registration Statement is required to be delivered under the Securities
Act of the occurrence of any event as a result of which the prospectus included
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 the light
of the circumstances then existing;

(f)         notify each Holder, promptly after it shall
receive notice or obtain knowledge thereof, of the issuance of any stop order
by the Commission suspending the effectiveness of such Registration Statement
or the initiation or threatening of any proceeding for that purpose and
promptly use its best efforts to prevent the issuance of any stop order or to
obtain its withdrawal if such stop order should be issued;

(g)        at the request of any such Holder, furnish:
(i) at the sole expense of the Company, an opinion dated as of the
effective date of the Registration Statement the counsel representing the
Company for the purposes of such registration, addressed to the underwriters, if
any, and to the Holder or Holders making such request, covering such matters as
such underwriters and Holder or Holders may reasonably request; and
(ii) letters dated as of the effective date of the Registration Statement
and as of the closing date, from the independent certified public accountants
of the Company, addressed to the underwriters, if any, and to the Holder or
Holders making such request, covering such matters as such underwriters and
Holder or Holders may reasonably request;

(h)        if requested by the Holders, cooperate
with the Holders to facilitate the timely preparation and delivery of
certificates representing the Registrable Securities to be delivered to a
transferee pursuant to a Registration Statement, which certificates shall be
free, to the extent permitted by this Agreement, of all restrictive legends,
and to enable such Registrable Securities to be in such denominations and
registered in such names as any such Holders may request; and

(i)            at any time after the Registrable Securities are covered
by an effective Registration Statement, the Company may deliver to the Holders
of such Registrable Securities a certificate (the “Suspension Certificate”) approved by
the Chief Executive Officer of the Company and signed by an officer of the
Company stating that the effectiveness of and sales of Registrable Securities
under the Registration Statement would:

(A) 
materially interfere with any transaction that would require the Company
to prepare financial statements under the Securities Act that the Company would
otherwise not be required to prepare in order to comply with its obligations
under the Exchange Act, or

(B) 
require public disclosure of any transaction of the type discussed in
Section 8.2(i)(A) prior to the time such disclosure might otherwise be
required;

Beginning five (5) Business Days after the receipt of a Suspension
Certificate by Holders of Registrable Securities, the Company may, in its
discretion, require such Holders of Registrable Securities to refrain from
selling or otherwise transferring or disposing of any Registrable Securities or
other Company securities then held by such Holders for a specified period of
time that is customary under the circumstances (not to exceed 30 days
during any 12-month period).  The Company
may impose stop transfer instructions to enforce any required agreement of the
Holders under this Section 8.2(i).

8.3          Discontinued Disposition

Each Holder agrees that, upon receipt of a notice from the Company
of the occurrence of any 

 16
 

event
of the kind described in Section 8.2(e) or Section 8.2(f), such Holder
will forthwith discontinue disposition of such Registrable Securities
under the 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 will use commercially
reasonable efforts to ensure that the use of the Prospectus may be resumed
as promptly as it practicable.

8.4          Non-Registration Event

The Company acknowledges and agrees that the Holders
will suffer material damages if the Registration Statement is not declared
effective by the Commission by the Required Effective Date and maintained in
the manner and within the time periods contemplated by Section 8.2 hereof, and
it would not be feasible to ascertain the extent of such damages with
precision.  Accordingly, if the
Registration Statement is not declared effective by the Commission on or prior
to the Required Effective Date (the “Non-Registration Event”), then, for so long
as the Non-Registration Event shall continue, the Company shall pay to each
Holder as liquidated damages for each month during the pendency of such
Non-Registration Event an amount equal to one (1%) percent per month (pro rated
for any portion thereof) of the aggregate value of the Warrant Shares
underlying the Holder’s Closing Warrants then held by such Holder (which shall
be measured at $4.00 per share); provided, however, that no amount in
liquidated damages shall be paid to any Holder pursuant to this Section 8.4 for
the Company’s failure to register the Warrant Shares if such failure is as a
result of an interpretation by the Commission that Securities Act Rule 415
prohibits such registration. Payments to be made pursuant to this Section 8.4
shall be due and payable to the Holders in immediately available funds within
ten (10) business days after receipt of written demand from a Holder.

8.5          Registration Expenses

The Company will be responsible for all expenses incurred by it in
connection with the preparation and filing of the Registration Statement,
regardless of whether any Registrable Securities are sold pursuant to such
Registration Statement.  All selling
expenses incurred by any Holder in connection with the Registration Statement
or the Registrable Securities, including broker or similar commissions, will be
borne by such Holder.

8.6          Indemnification

(a)           Indemnification
by Company.  The Company will indemnify each Holder, and
each Holder’s officers, directors, members, governors, employees, partners,
legal counsel, and accountants, and each person controlling such Holder within
the meaning of Section 15 of the Securities Act with respect to any
registration, qualification, or compliance effected pursuant to this
Section 8, and each underwriter, if any, and each person who controls,
within the meaning of Section 15 of the Securities Act, any underwriter,
against all expenses, claims, losses, damages, and liabilities (or actions,
proceedings, or settlements in respect of such expenses, claims, losses,
damages, and liabilities) arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any prospectus,
offering circular, or other document (including any related registration
statement, notification, or similar document) incident to any such
registration, qualification, or compliance, or based on any omission (or
alleged omission) to state in such document a material fact required to be
stated in such document or necessary to make the statements in such document
not misleading, or any violation by the Company of the Securities Act and any
applicable state securities laws or any rule or regulation under the Securities
Act or state securities laws applicable to the Company and relating to action
or inaction 

 17
 

required of the Company in
connection with any such registration, qualification, or compliance, and will
reimburse each such Holder, and each of such Holder’s officers, directors,
partners, legal counsel, and accountants, and each person controlling such
Holder, and each such underwriter, and each person who controls any such
underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating and defending or settling any such claim, loss,
damage, liability, or action; provided that the Company will not be liable in
any such case to the extent that any such claim, loss, damage, liability, or
expense arises out of or is based on any untrue statement or omission based
upon written information furnished to the Company by such Holder or underwriter
and stated to be specifically for use in such document.  The Parties expressly agree and acknowledge
that the indemnity agreement contained in this Section 8.6(a) will not
apply to amounts paid in settlement of any such loss, claim, damage, liability,
or action if such settlement is effected without the Company’s consent (which
consent will not be unreasonably withheld, delayed or conditioned).

(b)           Indemnification
by Holder.  Each Holder will, if Registrable Securities
held by such Holder are included in the securities as to which such
registration, qualification, or compliance is being effected, indemnify the
Company, and each of the Company’s directors, officers, legal counsel, and
accountants, and each underwriter, if any, of the Company’s securities covered
by such a registration statement, and each person who controls the Company or
such underwriter within the meaning of Section 15 of the Securities Act,
and each other such Holder, and each of their respective officers, directors,
and partners, and each person controlling such Holder or other Company
stockholder, against all claims, losses, damages, and liabilities (or actions
in respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular, or other document, or any omission
(or alleged omission) to state in such document a material fact required to be
stated in such document or necessary to make the statements in such document
not misleading, and will reimburse the Company, and such Holders, and
directors, officers, legal counsel, and accountants, and underwriters, and
control persons for any legal or any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability, or action, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering
circular, or other document in reliance upon and in conformity with written
information furnished to the Company by such Holder and stated to be
specifically for use in such document; provided that such Holder’s obligations
under this Section 8.6(b) will not apply to amounts paid in settlement of
any such claims, losses, damages, or liabilities (or actions in respect of such
claims, losses, damages, or liabilities) if such settlement is effected without
such Holder’s consent (which consent will not be unreasonably withheld, delayed
or conditioned); and provided further that in no event will any indemnity under
this Section 8.6(b) exceed the net proceeds.  For purposes of this Section 8.6(b) and
Section 8.6(d), the term “net proceeds,” with respect to any particular
Holder, means the proceeds from the offering received by such Holder after
deducting underwriters’ commissions, discounts, and expenses attributable to
the Registrable Securities sold by such Holder.

(c)           Indemnification
Procedures.  Each party entitled to indemnification under
this Section 8.6 (the “Indemnified Party”) will give
notice to the party required to provide indemnification (the “Indemnifying Party”)
promptly after such Indemnified Party has actual knowledge of any claim as to
which indemnity may be sought, and will permit the Indemnifying Party to assume
the defense of such claim or any litigation resulting from such claim; provided
that counsel for the Indemnifying Party who will conduct the defense of such
claim or any litigation resulting from such claim, will be approved by the
Indemnified Party (whose approval will not be unreasonably withheld), and the
Indemnified Party may participate in such defense at such Indemnified Party’s
expense.  Notwithstanding the foregoing,
any Indemnified Party’s failure to give notice as provided in this
Section 8.6(c) will not relieve the Indemnifying Party of the Indemnifying
Party’s obligations under this Section 8.6 to the extent such failure is
not prejudicial.  No Indemnifying Party,
in the defense of any such claim or litigation, will, 

 18
 

except with the consent of
each Indemnified Party, consent to entry of any judgment or enter into any
settlement that does not include as an unconditional term of such judgment or such
settlement the claimant’s or plaintiff’s release of such Indemnified Party from
all liability in respect to such claim or litigation.  Each Indemnified Party will furnish such
information regarding such Indemnified Party or the claim in question as an Indemnifying
Party may reasonably request in writing and as will be reasonably required in
connection with defense of such claim and litigation resulting from such claim.

(d)           Indemnification
Unavailability.  If the indemnification provided for in this
Section 8.6 is held by a court of competent jurisdiction to be unavailable
to an Indemnified Party with respect to any loss, liability, claim, damage, or
expense referred to in this Section 8.6, then the Indemnifying Party,
instead of indemnifying such Indemnified Party under Section 8.6(a) or
Section 8.6(b), will contribute to the amount paid or payable by such
Indemnified Party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party, on the one hand, and of the Indemnified Party, on the other
hand, in connection with the statements or omissions that resulted in such
loss, liability, claim, damage, or expense as well as any other relevant
equitable considerations; provided, however, that in no event will any
contribution by a Holder under this Section 8.6(d) exceed the net proceeds
(as defined in Section 8.6(b)).  The
relative fault of the Indemnifying Party and of the Indemnified Party will be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the Indemnifying Party or by the Indemnified
Party and the Parties’ relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

8.7          Information from Holder

Each Holder will furnish to the Company such information regarding such
Holder and the distribution proposed by such Holder as the Company may
reasonably request in writing and as will be reasonably required in connection
with any registration, qualification, or compliance referred to in this
Section 8.

8.8          Rule 144 Reporting

With a view to making available the benefits of certain Commission
rules and regulations that may permit the sale of the Warrant Shares underlying
the Initial Interest Warrant and the Quarterly Interest Warrant, if exercised
(the “Restricted
Securities”), to the public without registration, the Company
agrees to:

(a)           file with the Commission in a timely manner
all reports and other documents required of the Company under the Securities
Act and the Exchange Act; and

(b)           so long as a Holder owns any Restricted
Securities, furnish to the Holder, promptly upon the Holder’s written request,
a written statement by the Company as to the Company’s compliance with the
reporting requirements of Rule 144 and the Exchange Act.

Agreement will inure to the benefit of, and be binding upon, the parties’
respective successors, assigns, heirs, executors, and administrators.

 20
 

9.8          Delays or Omissions 

It is agreed that no delay or omission to exercise
any right, power or remedy accruing to any party, upon any breach, default or
noncompliance by another party under any of the Transaction Agreements shall
impair any such right, power or remedy, nor shall it be construed to be a
waiver of any such breach, default or noncompliance, or any acquiescence
therein, or of or in any similar breach, default or noncompliance thereafter
occurring.  It is further agreed that any
waiver, permit, consent or approval of any kind or character on any Holder’s
part of any breach, default or noncompliance under any of the Transaction
Agreements or any waiver on such party’s part of any provisions or conditions
of any of the Transaction Agreements must be in writing and shall be effective

  Secured Notes Series

  

 

FOR VALUE
RECEIVED, the
undersigned, MedicalCV, Inc., a Minnesota corporation (the “Borrower”), with its
principal executive office at 9725 South Robert Trail, Inver Grove Heights, Minnesota
55077, hereby promises to pay to the order of                                      
(the “Holder”),
or its assigns, the principal sum of $                                 ,
or such greater or lesser amount as shall then equal the outstanding principal
amount hereof (the “Principal Amount”), together
with interest from the date of this Secured Promissory Note (this “Note”)
on the outstanding principal balance at an annual rate equal to 11% per annum. All
payments of principal and interest shall be made in immediately available funds
in lawful money of the United States.

This Note is one of multiple
notes in the 2007 Secured Notes Series (collectively, the “Notes”) referred to
in that certain Secured Note Purchase Agreement dated April 20, 2007 by and
among the Company, the Holder and certain other holders (the “Note Purchase
Agreement”).  The
Notes are secured by a first priority security interest in and to the Company’s
assets, as set forth in that certain Security Agreement April 20, 2007 by and
among the Company, the Holder and certain other holders (the “Security Agreement”).  Capitalized
terms not otherwise defined in this Note have the meanings placed on them in
the Note Purchase Agreement and/or the Security Agreement.

1.             Payment
of Principal and Interest

(a)   The entire unpaid principal
balance, together with any accrued but unpaid interest and other unpaid charges
or fees hereunder, shall be due and payable on the date that is thirty-six (36)
months following the Effective Date of the Note Purchase Agreement (the “Maturity Date”).

(b)   During the initial twelve
(12) month period following the Effective Date, interest on the Note will
accrue and be added to the Principal Amount of the Note.  Within thirty (30) days following the end of such
12-month period, the Company shall issue to the Holder a five-year Warrant, in
substantially the form attached to the Note Purchase Agreement as Exhibit B2,
which shall entitle the Holder to purchase such number of shares of the Company’s
Common Stock that is equal to the quotient obtained by dividing (i) 60% of the
accrued interest for the initial 12-month period by (ii) $4.00.

(c)   Following the initial
12-month period, the Company will have the right to (i) pay the accrued
interest on the Note quarterly in arrears or (ii) allow the interest for such
quarter continue to accrue and be added to the Principal Amount of the
Note.  Any payment of accrued interest
must be made to the Holder on or before the 15th day following the end of such quarter.  If the Company elects to have the quarterly
interest added to the Principal Amount of the Note, then the Company shall
issue to the Holder, within thirty (30) days following the end of such quarter,
a five-year Warrant, in substantially the 

form attached to the Note Purchase Agreement as
Exhibit B2, entitling the Holder to purchase such number of shares of the
Company’s Common Stock that is equal to the quotient obtained by dividing (i)
60% of the accrued interest for the quarter by (ii) $4.00.

(d)   The Borrower shall have the
right to prepay this Note, in part or in whole, at any time during the term of
this Note, subject to a premium payment (the “Premium Payment”) payable to the
Holder as follows:

(i)   8% of the Principal Amount if
prepayment is made within the first 12-month period following the Effective
Date;

(ii)  6% of the Principal Amount if
prepayment is made within the second 12-month period following the Effective
Date; and

(iii) 3% of the Principal Amount if prepayment is made within the third
12-month period following the Effective Date.

The
Prepayment Premium shall be paid to the Holder in immediately available funds
simultaneously with the Prepayment.  If
the Borrower elects to prepay less than the whole Principal Amount then
outstanding, then the Prepayment Premium shall apply only to such portion of
the Principal Amount that is being prepaid at that time.  The Prepayment Premium shall not apply if the
prepayment of the Note is a result of a change of control of the Company.

(e)   Notwithstanding anything
herein to the contrary, if any payment of Principal Amount or interest (or,
pursuant to Section 1(b) or (c) above, a Warrant issuance) becomes due on a
Saturday, a Sunday or a day on which banks in the State of Minnesota are
authorized or required by law to close, the due date thereof shall be extended
to the immediately succeeding day which is not a Saturday, a Sunday or a day on
which the banks in the State of Minnesota are closed, and any applicable interest
thereon shall accrue during the period of such extension at the rate provided
for herein.

(f)    If the Principal Amount of
the Note is prepaid in full prior to the Maturity Date, the Company agrees to
issue to the Holder, at the time of the Prepayment, the Warrant that would
otherwise have been issuable pursuant to Section 1(b) or 1(c) for such period,
as applicable, calculated on a pro rata basis for that period.

2.             Warrant
Rights.  The Holder shall be entitled to receive Warrants
to purchase shares of the Borrower’s common stock, as set forth in the Note
Purchase Agreement and in Sections 1(b) and 1(c) of this Note (without
duplication).

3.             Rights
of Holder.  Upon an Event of Default, the rights and
remedies of the Holder are as set forth in the Note Purchase Agreement and the Security
Agreement, which, among other things, 
provide that the with respect to any action taken in connection with the
Note Purchase Agreement or the Security Agreement, the Holders of the 2007
Secured Note Series shall act in accordance with and under the directions of
the Holders holding a majority-in-interest of the outstanding Principal Amount
of the Notes, or a designee appointed by such Holders. 

4.             Security.  This
Note and the payment of all principal, interest and other sums hereunder is
secured by a security interest in the Collateral, pursuant to the Note Purchase
Agreement and the Security Agreement.

5.             Amendments.  Changes
in or additions to this Note may be made, or compliance with any term,
covenant, agreement, condition or provision set forth herein may be omitted or
waived (either generally or in a particular instance and either retroactively
or prospectively), only in writing.

6.             Waiver.  The
failure of the Holder to insist, in any one or more instances, on performance
of any of the terms, covenants and conditions hereof shall not be construed as
a waiver or relinquishment of any rights granted hereunder or of the future
performance of any such terms, covenants or conditions, but the obligation of
the Borrower with respect thereto shall continue to be in full force and
effect.

7.             Benefits;

hereunder shall inure to the benefit of its successors and assigns, and Borrower
acknowledges that Holder may pledge this Note to its Holders. The Borrower may
not assign any rights or obligations hereunder without the prior written
consent of the Holder, and any such attempted assignment shall be null and void
and of no force or effect.

8.             Notices.  All notices, requests and demands to or upon the parties hereto shall
be deemed to have been given or made when deposited in the mail, certified or
registered, postage prepaid, addressed to the address of the party set forth in
the Note Purchase Agreement or such other address as any party may request by
notice given as aforesaid.

9.             Collection.  The Borrower agrees to pay any costs and expenses (including reasonable
attorneys’ fees and disbursements) incurred by the Holder in the collection of
any and all amounts due under this Note that are not paid when due and in the

provision hereof and all other provisions hereof shall remain in full force and

a)             Exercise of Warrant.  Exercise of the purchase rights represented
by this Warrant may be made, in whole or in part, at any time or times on or
after the Initial Exercise Date and on or before the Termination Date by
delivery to the Company of a duly executed facsimile or “.pdf” copy of the
Notice of Exercise Form annexed hereto (or such other office or agency of the
Company as it may designate by notice in writing to the registered Holder at
the address of such Holder appearing on the books of the Company); and, within
3 Trading Days of the date said Notice of Exercise is delivered to the Company,
the Company shall have received payment of the aggregate Exercise Price of the
shares thereby purchased by wire transfer or cashier’s check drawn on a United
States bank, unless this Warrant is being exercised pursuant to the cashless
exercise 

 2
 

provision set forth in
Section 2(c) below.  Notwithstanding
anything herein to the contrary, the Holder shall not be required to physically
surrender this Warrant to the Company until the Holder has purchased all of the
Warrant Shares available hereunder and the Warrant has been exercised in full,
in which case, the Holder shall surrender this Warrant to the Company for cancellation
within 3 Trading Days of the date the final Notice of Exercise is delivered to
the Company.  Partial exercises of this
Warrant resulting in purchases of a portion of the total number of Warrant
Shares available hereunder shall have the effect of lowering the outstanding
number of Warrant Shares purchasable hereunder in an amount equal to the
applicable number of Warrant Shares purchased. 
The Holder and the Company shall maintain records showing the number of Warrant
Shares purchased and the date of such purchases.  In the event of any dispute or discrepancy,
the records of the Company shall be controlling and determinative in the
absence of manifest error.  The Holder
and any assignee, by acceptance of this Warrant, acknowledge and agree that, by
reason of the provisions of this paragraph, following the purchase of a portion
of the Warrant Shares hereunder, the number of Warrant Shares available for
purchase hereunder at any given time may be less than the amount stated on the
face hereof.

b)            Exercise Price.  The
exercise price per share of the Common Stock under this Warrant shall be $4.00,
subject to adjustment hereunder (the “Exercise Price”).

c)             Cashless Exercise.  If a Notice of Exercise Form is delivered at
a time when (i) a registration statement permitting the Holder to resell the
Warrant Shares is required to be effective but is not then effective, or (ii)
the prospectus forming a part thereof is not then available to the Holder for
the resale of the Warrant Shares, then this Warrant may also be exercised at
such time by means of a “cashless exercise” in which the Holder shall be
entitled to receive a certificate for the number of Warrant Shares equal to the
quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) =                    the VWAP on
the Trading Day immediately preceding the date of such election;

(B) =                      the Exercise
Price of this Warrant, as adjusted; and

(X) =                     the number of
Warrant Shares issuable upon exercise of this Warrant in accordance with the
terms of this Warrant by means of a cash exercise rather than a cashless
exercise.

d)            Mechanics of Exercise.

i.              Authorization of Warrant Shares.  The Company covenants that all Warrant Shares
which may be issued upon the exercise of the purchase rights represented by
this Warrant will, upon exercise of the purchase rights represented by this
Warrant, be duly authorized, validly issued, fully paid and nonassessable and
free from all taxes, liens and charges created by the Company in respect of the
issue thereof (other than taxes in respect of any transfer occurring
contemporaneously with such issue).

 3
 

ii.             Delivery of Certificates Upon
Exercise.  Certificates for shares
purchased hereunder shall be transmitted by the transfer agent of the Company
to the Holder by crediting the account of the Holder’s prime broker with the
Depository Trust Company through its Deposit Withdrawal Agent Commission (“DWAC”)
system if the Company is a participant in such system, and otherwise by
physical delivery to the address specified by the Holder in the Notice of
Exercise within 3 Trading Days from the delivery to the Company of the Notice
of Exercise Form, surrender of this Warrant (if required) and payment of the
aggregate Exercise Price as set forth above (“Warrant Share Delivery Date”).  This Warrant shall be deemed to have been
exercised on the date (a) the Exercise Price is received by the Company or (b)
notification to the Company that this Warrant is being exercised pursuant to a
cashless exercise provision set forth in Section 2(c) above.  The Warrant Shares shall be deemed to have
been issued, and Holder or any other person so designated to be named therein
shall be deemed to have become a holder of record of such shares for all
purposes, as of the date the Warrant has been exercised by payment to the
Company of the Exercise Price (or by cashless exercise, if permitted) and all
taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi)
prior to the issuance of such shares, have been paid.

iii.            Delivery of New Warrants Upon
Exercise.  If this Warrant shall have
been exercised in part, the Company shall, at the request of a Holder and upon
surrender of this Warrant certificate, at the time of delivery of the
certificate or certificates representing Warrant Shares, deliver to Holder a
new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant
Shares called for by this Warrant, which new Warrant shall in all other
respects be identical with this Warrant.

iv.            Rescission Rights.  If the Company fails to cause its transfer
agent to transmit to the Holder a certificate or certificates representing the
Warrant Shares pursuant to this Section 2(d) by the Warrant Share Delivery
Date, then the Holder will have the right to rescind such exercise.

v.             No Fractional Shares or Scrip.  No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant.  As to any fraction of a share which Holder
would otherwise be entitled to purchase upon such exercise, the Company shall
at its election, either pay a cash adjustment in respect of such final fraction
in an amount equal to such fraction multiplied by the Exercise Price or round
up to the next whole share.

vi.            Charges, Taxes and Expenses.  Issuance of certificates for Warrant Shares
shall be made without charge to the Holder for any issue or transfer tax or
other incidental expense in respect of the issuance of such certificate, all of
which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder; provided, however, that in the event
certificates for Warrant Shares are to be issued in a name other than the name
of the Holder, this Warrant when surrendered for exercise shall be accompanied
by the Assignment Form attached 

 4
 

hereto duly executed by
the Holder; and the Company may require, as a condition thereto, the payment of
a sum sufficient to reimburse it for any transfer tax incidental thereto.

vii.           Closing of Books.  The Company will not close its shareholder
books or records in any manner which prevents the timely exercise of this
Warrant, pursuant to the terms hereof.

Section 3.               Certain Adjustments.

a)             Stock Dividends and Splits.  If the Company, at any time while this
Warrant is outstanding: (A) pays a stock dividend or otherwise make a
distribution or distributions on shares of its Common Stock or any other equity
or equity equivalent securities payable in shares of Common Stock (which, for
avoidance of doubt, shall not include any shares of Common Stock issued by the
Company upon exercise of this Warrant, any other warrant or any option), (B)
subdivides outstanding shares of Common Stock into a larger number of shares,
(C) combines (including by way of reverse stock split) outstanding shares of Common
Stock into a smaller number of shares, or (D) issues by reclassification of
shares of the Common Stock any shares of capital stock of the Company, then in
each case the Exercise Price shall be multiplied by a fraction of which the
numerator shall be the number of shares of Common Stock (excluding treasury
shares, if any) outstanding immediately before such event and of which the
denominator shall be the number of shares of Common Stock outstanding
immediately after such event and the number of shares issuable upon exercise of
this Warrant shall be proportionately adjusted. 
Any adjustment made pursuant to this Section 3(a) shall become effective
immediately after the record date for the determination of shareholders
entitled to receive such dividend or distribution and shall become effective
immediately after the effective date in the case of a subdivision, combination
or re-classification.

b)            Adjustment for Issuance of Shares
of Common Stock Below Exercise Price. 
From the date hereof until 12 months after the Closing Date (the “Adjustment
Period”), the Exercise Price shall be subject to adjustment from time to
time as provided in this Section 3(b).

i.              If
during the Adjustment Period, the Company issues or sells, or in accordance
with this Section 3(b) is deemed to have issued or sold, any shares of
Common Stock (excluding Excluded Securities) for a consideration per share (the
“New Securities Issuance Price”)
less than a price (the “Applicable
Price”) equal to the Exercise Price in effect immediately prior to
such time, then immediately after such issue or sale, the Exercise Price then
in effect shall be reduced to an amount equal to the New Securities Issuance
Price.

ii.             For
purposes of determining the adjusted Exercise Price under Section 3(b) hereof, the
following will be applicable:

(A)          Issuance of Rights or Options.
If the Company in any manner grants or sells any Options and the lowest price
per share for which one share of Common Stock is issuable upon the exercise of
any such Option or upon 

 5
 

conversion, exchange or exercise of any Convertible
Securities issuable upon exercise of such Option is less than the Applicable
Price, then such share of Common Stock shall be deemed to be outstanding and to
have been issued and sold by the Company at the time of the granting or sale of
such Option for such price per share. For purposes of this
Section 3(b)(ii)(A), the “lowest price per share for which one share of
Common Stock is issuable upon the exercise of any such Option or upon
conversion, exchange or exercise of any Convertible Securities issuable upon
exercise of such Option” shall be equal to the sum of the lowest amounts of
consideration (if any) received or receivable by the Company with respect to
any one share of Common Stock upon granting or sale of the Option, upon
exercise of the Option and upon conversion, exchange or exercise of any
Convertible Security issuable upon exercise of such Option. No further
adjustment of the Exercise Price shall be made upon the actual issuance of such
Common Stock or of such Convertible Securities upon the exercise of such
Options or upon the actual issuance of such Common Stock upon conversion,
exchange or exercise of such Convertible Securities.  “Convertible Securities” means any
evidence of indebtedness, shares or securities, in each case convertible into
or exchangable for Common Stock.  “Options”
means rights, options or warrants to subscribe for, purchase or otherwise
acquire shares of Common Stock or Convertible Securities.

(B)           Issuance of Convertible Securities.
If the Company in any manner issues or sells any Convertible Securities and the
lowest price per share for which one share of Common Stock is issuable upon
such conversion, exchange or exercise thereof is less than the Applicable
Price, then such share of Common Stock shall be deemed to be outstanding and to
have been issued and sold by the Company at the time of the issuance or sale of
such Convertible Securities for such price per share. For the purposes of this
Section 3(b)(ii)(B), the “lowest price per share for which one share of Common
Stock is issuable upon such conversion, exchange or exercise” shall be equal to
the sum of the lowest amounts of consideration (if any) received or receivable
by the Company with respect to any one share of Common Stock upon the issuance
or sale of the Convertible Security and upon the conversion, exchange or
exercise of such Convertible Security. No further adjustment of the Exercise
Price shall be made upon the actual issuance of such Common Stock upon
conversion, exchange or exercise of such Convertible Securities, and if any
such issue or sale of such Convertible Securities is made upon exercise of any
Options for which adjustment of the Exercise Price had been or are to be made
pursuant to other provisions of this Section 3(b)(ii), no further adjustment of
the Exercise Price shall be made by reason of such issue or sale.

(C)           Change in Option Price or
Conversion Rate. If the purchase or exercise price provided for in any
Options, or the additional consideration, if any, payable upon the issue,
conversion, exchange or exercise of any Convertible Securities, or the rate at
which any Convertible Securities are convertible into or exchangeable or
exercisable for Common Stock changes at any time, the Exercise Price in effect
at the time of such change shall be adjusted to the Exercise Price which would
have been in effect at such time had such Options or Convertible 

 6
 

Securities provided for such changed purchase price,
additional consideration or changed conversion rate, as the case may be, at the
time initially granted, issued or sold. For purposes of this Section
3(b)(ii)(C), if the terms of any Option or Convertible Security that was
outstanding as of the Closing Date are changed in the manner described in the
immediately preceding sentence, then such Option or Convertible Security and
the Common Stock deemed issuable upon exercise, conversion or exchange thereof
shall be deemed to have been issued as of the date of such change. No
adjustment shall be made if such adjustment would result in an increase of the
Exercise Price then in effect. 
Notwithstanding the foregoing, no adjustment shall be made to the
Exercise Price of this Warrant due to anti-dilution adjustments made to securities
outstanding as of the Closing Date as a result of the issuance of Securities
pursuant to the Transaction Documents.

(D)          Calculation of Consideration
Received. In case any Option is issued in connection with the issue or sale
of other securities of the Company, together comprising one integrated
transaction in which no specific consideration is allocated to such Options by
the parties thereto, the Options will be deemed to have been issued for a
consideration of $0.01. If any Common Stock, Options or Convertible Securities
are issued or sold or deemed to have been issued or sold for cash, the
consideration received therefor will be deemed to be the gross amount received
by the Company therefor. If any Common Stock, Options or Convertible Securities
are issued or sold for a consideration other than cash, the amount of the
consideration other than cash received by the Company will be the fair value of
such consideration, except where such consideration consists of marketable
securities, in which case the amount of consideration received by the Company
will be the arithmetic average of the closing sale prices of such securities
during the ten (10) consecutive trading days ending on the date of receipt
of such securities. The fair value of any consideration other than cash or
securities will be determined jointly by the Company and the holders of at
least a majority in interest of the Warrants then outstanding.

(E)           Exceptions to Adjustment of
Exercise Price. Notwithstanding the foregoing, no adjustment will be made
under this Section 3(b) in respect of Excluded Securities. “Excluded
Securities” means the issuance of (a) shares of Common Stock or options to
employees, officers or directors of, or consultants to, the Company pursuant to
any stock option agreement, stock option plan or equity incentive plan duly
adopted by a majority of the non-employee members of the Board of Directors of
the Company or a majority of the members of a committee of non-employee
directors  established for such purpose (for
purposes of clarity, the issuance of shares of Common Stock upon exercise of
options granted pursuant to a stock option agreement, stock option plan or
equity incentive plan subsequent to the date hereof shall also be Excluded
Securities), (b) securities upon the exercise or exchange of or conversion of (i)
any Securities issued in connection with the Purchase Agreement; (ii)
securities to a registered broker-dealer in connection with the transactions
contemplated by the Purchase Agreement; and/or (iii) other securities or rights
exercisable or exchangeable for or convertible into shares of Common Stock
which are issued and outstanding on 

 7
 

the date of the
Purchase Agreement, provided that such securities have not been amended since
the date of the Purchase Agreement (other than on a non-discretionary basis pursuant
to the pre-existing anti-dilution provisions thereof) to increase the number of
such securities or to decrease the exercise, exchange or conversion price of
any such securities, (c) securities issued pursuant to acquisitions or
strategic transactions approved by  a majority of
the disinterested directors, provided any such issuance shall only be to a
Person which is, itself or through its subsidiaries, an operating company in a
business synergistic with the business of the Company and in which the Company
receives benefits in addition to the investment of funds, but shall not include
a transaction in which the Company is issuing securities primarily for the
purpose of raising capital or to an entity whose primary business is investing
in securities, (d) shares of Common Stock or other securities issued in
connection with any stock split, stock dividend or recapitalization of the
Company (subject to Section 3(a) hereof), and (e) shares of Common Stock or
other securities issued in connection with any registered primary public
offering.

c)             Calculations.  All calculations under this Section 3 shall
be made to the nearest cent or the nearest 1/100th of a share, as the case may
be.  For purposes of this Section 3, the
number of shares of Common Stock deemed to be issued and outstanding as of a
given date shall be the sum of the number of shares of Common Stock (excluding
treasury shares, if any) issued and outstanding.

d)            Voluntary Adjustment By 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.

e)             Notice to Holders.

i.              Adjustment to Exercise Price.  Whenever the Exercise Price is adjusted
pursuant to any provision of this Section 3, the Company shall promptly mail to
each Holder a notice setting forth the Exercise Price after such adjustment and
setting forth a brief statement of the facts requiring such adjustment.

ii.             Notice to Allow Exercise by Holder.  If (A) the Company shall declare a dividend
(or any other distribution in whatever form) on the Common Stock; (B) the
Company shall declare a special nonrecurring cash dividend on or a redemption
of the Common Stock; (C) the Company shall authorize the granting to all
holders of the Common Stock rights or warrants to subscribe for or purchase any
shares of capital stock of any class or of any rights; (D) the approval of any
shareholders of the Company shall be required in connection with any reclassification
of the Common Stock, any consolidation or merger to which the Company is a
party, any sale or transfer of all or substantially all of the assets of the
Company, of any compulsory share exchange whereby the Common Stock is converted
into other securities, cash or property; (E) the Company shall authorize the
voluntary or involuntary dissolution, liquidation or winding up of the affairs
of the Company; then, in each case, the Company shall cause to be mailed to the
Holder at its last address as it shall appear upon the Warrant Register of the 

 8
 

Company, at least 20
calendar days prior to the applicable record or effective date hereinafter
specified, a notice stating (x) the date on which a record is to be taken for
the purpose of such dividend, distribution, redemption, rights or warrants, or
if a record is not to be taken, the date as of which the holders of the Common
Stock of record to be entitled to such dividend, distributions, redemption,
rights or warrants are to be determined or (y) the date on which such
reclassification, consolidation, merger, sale, transfer or share exchange is
expected to become effective or close, and the date as of which it is expected
that holders of the Common Stock of record shall be entitled to exchange their
shares of the Common Stock for securities, cash or other property deliverable
upon such reclassification, consolidation, merger, sale, transfer or share
exchange; provided that the failure to mail such notice or any defect therein
or in the mailing thereof shall not affect the validity of the corporate action
required to be specified in such notice. 
The Holder is entitled to exercise this Warrant during the 20-day period
commencing on the date of such notice to the effective date of the event
triggering such notice.

Section 4.               Transfer of Warrant.

a)             Transferability.  Subject to compliance with any applicable
securities laws and the conditions set forth in Section 4(d) hereof, this
Warrant and all rights hereunder (including, without limitation, any
registration rights) are transferable, in whole or in part, upon surrender of
this Warrant at the principal office of the Company or its designated agent,
together with a written assignment of this Warrant substantially in the form
attached hereto duly executed by the Holder or its agent or attorney and funds
sufficient to pay any transfer taxes payable upon the making of such
transfer.  Upon such surrender and, if
required, such payment, the Company shall execute and deliver a new Warrant or
Warrants in the name of the assignee or assignees and in the denomination or
denominations specified in such instrument of assignment, and shall issue to
the assignor a new Warrant evidencing the portion of this Warrant not so
assigned, and this Warrant shall promptly be cancelled.  A Warrant, if properly assigned, may be
exercised by a new holder for the purchase of Warrant Shares without having a
new Warrant issued.

b)            New Warrants.  This Warrant may be divided or combined with
other Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued, signed by the Holder or its agent or
attorney.  Subject to compliance with
Section 4(a), as to any transfer which may be involved in such division or
combination, the Company shall execute and deliver a new Warrant or Warrants in
exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice.

c)             Warrant Register.  The Company shall register this Warrant, upon
records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time.  The Company may deem and treat the registered
Holder of this Warrant as the absolute owner hereof for the purpose of any
exercise hereof or any distribution to the Holder, and for all other purposes,
absent actual notice to the contrary.

 9
 

d)            Transfer Restrictions.  If, at the time of the surrender of this
Warrant in connection with any transfer of this Warrant, the transfer of this
Warrant shall not be registered pursuant to an effective registration statement
under the Securities Act and under applicable state securities or blue sky
laws, the Company may require, as a condition of allowing such transfer (i)
that the Holder or transferee of this Warrant, as the case may be, furnish to
the Company a written opinion of counsel (which opinion shall be in form,
substance and scope customary for opinions of counsel in comparable
transactions) to the effect that such transfer may be made without registration
under the Securities Act and under applicable state securities or blue sky
laws, (ii) that the Holder or transferee execute and deliver to the Company an
investment letter in form and substance acceptable to the Company and (iii)
that the transferee be an “accredited investor” as defined in Rule 501(a)(1),
(a)(2), (a)(3), (a)(7), or (a)(8) promulgated under the Securities Act or a “qualified
institutional buyer” as defined in Rule 144A(a) under the Securities Act.

Section 5.               Miscellaneous.

a)             No Rights as Shareholder Until
Exercise.  This Warrant does not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof as set forth in Section 2(d)(ii).

b)            Loss, Theft, Destruction or
Mutilation of Warrant.  The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any
stock certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which, in
the case of the Warrant, shall not include the posting of any bond), and upon
surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like
tenor and dated as of such cancellation, in lieu of such Warrant or stock
certificate.

c)             Saturdays, Sundays, Holidays,
etc.  If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall not be a Business Day, then such action may be taken or such right
may be exercised on the next succeeding Business Day.

d)            Authorized Shares.

The Company covenants
that during the period the Warrant is outstanding, it will reserve from its
authorized and unissued Common Stock a sufficient number of shares to provide
for the issuance of the Warrant Shares upon the exercise of any purchase rights
under this Warrant.  The Company further
covenants that its issuance of this Warrant shall constitute full authority to
its officers who are charged with the duty of executing stock certificates to
execute and issue the necessary certificates for the Warrant Shares upon the
exercise of the purchase rights under this Warrant.  The Company will take all such reasonable
action as may be necessary to assure that such Warrant Shares may be issued as
provided herein without violation of any applicable law or regulation, or 

 10
 

of any requirements of the Trading Market upon which
the Common Stock may be listed.

Except and to the extent
as waived or consented to by the Holder, the Company shall not by any action,
including, without limitation, amending its articles of incorporation or
through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid
or seek to avoid the observance or performance of any of the terms of this
Warrant, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such actions as may be necessary or
appropriate to protect the rights of Holder as set forth in this Warrant
against impairment.  Without limiting the
generality of the foregoing, the Company will (a) not increase the par value of
any Warrant Shares above the amount payable therefor upon such exercise
immediately prior to such increase in par value, (b) take all such action as
may be necessary or appropriate in order that the Company may validly and
legally issue fully paid and nonassessable Warrant Shares upon the exercise of
this Warrant, and (c) use commercially reasonable efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction thereof as may be necessary to enable the Company to perform its
obligations under this Warrant.

Before taking any action
which would result in an adjustment in the number of Warrant Shares for which
this Warrant is exercisable or in the Exercise Price, the Company shall obtain
all such authorizations or exemptions thereof, or consents thereto, as may be
necessary from any public regulatory body or bodies having jurisdiction
thereof.

e)             Jurisdiction.  All questions concerning the construction,
validity, enforcement and interpretation of this Warrant shall be determined in
accordance with the provisions of the Purchase Agreement.

f)             Restrictions.  The Holder acknowledges that the Warrant
Shares acquired upon the exercise of this Warrant, if not registered, will have
restrictions upon resale imposed by state and federal securities laws.

g)            Nonwaiver and Expenses.  No course of dealing or any delay or failure
to exercise any right hereunder on the part of Holder shall operate as a waiver
of such right or otherwise prejudice the Company’s or the Holder’s rights,
powers or remedies, notwithstanding the fact that all rights hereunder
terminate on the Termination Date.  If
the Company or a Holder willfully and knowingly fails to comply with any
provision of this Warrant, which results in any material damages to the Holder
or Company (as the case may be), the breaching party shall pay to the other
party such amounts as shall be sufficient to cover any costs and expenses
including, but not limited to, reasonable attorneys’ fees, including those of
appellate proceedings, incurred by the non-breaching party in collecting any
amounts due pursuant hereto or in otherwise enforcing any of its rights, powers
or remedies hereunder.

 11
 

h)            Notices.  Any notice, request or other document
required or permitted to be given or delivered to the Holder by the Company
shall be delivered in accordance with the notice provisions of the Purchase
Agreement.

i)              Limitation of Liability.  No provision hereof, in the absence of any
affirmative action by Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of Holder, shall
give rise to any liability of Holder for the purchase price of any Common Stock
or as a shareholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

j)              Remedies.  Holder, in addition to being entitled to
exercise all rights granted by law, including recovery of damages, will be
entitled to seek specific performance of its rights under this Warrant.  The Company agrees that monetary damages
would not be adequate compensation for any loss incurred by reason of a breach
by it of the provisions of this Warrant and hereby agrees to waive and not to
assert the defense in any action for specific performance that a remedy at law
would be adequate.

k)             Successors and Assigns.  Subject to applicable securities laws, this
Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors of the Company and the successors
and permitted assigns of Holder.  The
provisions of this Warrant are intended to be for the benefit of all Holders
from time to time of this Warrant and shall be enforceable by any such Holder
or holder of Warrant Shares.

l)              Amendment.  This Warrant may be modified or amended or
the provisions hereof waived with the written consent of the Company and the
Holder.

m)            Severability.  Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Warrant.

n)            Headings.  The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

Section 2.               Exercise.

a)             Exercise of Warrant.  Exercise of the purchase rights represented
by this Warrant may be made, in whole or in part, at any time or times on or
after the Initial Exercise Date and on or before the Termination Date by
delivery to the Company of a duly executed facsimile or “.pdf” copy of the
Notice of Exercise Form annexed hereto (or such other office or agency of the
Company as it may designate by notice in writing to the registered Holder at
the address of such Holder appearing on the books of the Company); and, within
3 Trading Days of the date said Notice of Exercise is delivered to the Company,
the Company shall have received payment of the aggregate Exercise Price of the
shares thereby purchased by wire transfer or cashier’s check drawn on a United

herein to the contrary, the Holder shall not be

 2
 

required to physically
surrender this Warrant to the Company until the Holder has purchased all of the
Warrant Shares available hereunder and the Warrant has been exercised in full,
in which case, the Holder shall surrender this Warrant to the Company for
cancellation within 3 Trading Days of the date the final Notice of Exercise is
delivered to the Company.  Partial
exercises of this Warrant resulting in purchases of a portion of the total
number of Warrant Shares available hereunder shall have the effect of lowering

equal to the applicable number of Warrant Shares purchased.  The Holder and the Company shall maintain
records showing the number of Warrant Shares purchased and the date of such
purchases.  In the event of any dispute
or discrepancy, the records of the Company shall be controlling and
determinative in the absence of manifest error. 
The Holder and any assignee, by acceptance of this Warrant, acknowledge
and agree that, by reason of the provisions of this paragraph, following the
purchase of a portion of the Warrant Shares hereunder, the number of Warrant
Shares available for purchase hereunder at any given time may be less than the
amount stated on the face hereof.

b)            Exercise Price.  The
exercise price per share of the Common Stock under this Warrant shall be $4.00,
subject to adjustment hereunder (the “Exercise Price”).

c)             Not applicable.

d)            Mechanics of Exercise.

i.              Authorization of Warrant Shares.  The Company covenants that all Warrant Shares
which may be issued upon the exercise of the purchase rights represented by
this Warrant will, upon exercise of the purchase rights represented by this
Warrant, be duly authorized, validly issued, fully paid and nonassessable and
free from all taxes, liens and charges created by the Company in respect of the
issue thereof (other than taxes in respect of any transfer occurring
contemporaneously with such issue).

ii.             Delivery of Certificates Upon
Exercise.  Certificates for shares
purchased hereunder shall be transmitted by the transfer agent of the Company
to the Holder by crediting the account of the Holder’s prime broker with the
Depository Trust Company through its Deposit Withdrawal Agent Commission (“DWAC”)
system if the Company is a participant in such system, and otherwise by
physical delivery to the address specified by the Holder in the Notice of
Exercise within 3 Trading Days from the delivery to the Company of the Notice
of Exercise Form, surrender of this Warrant (if required) and payment of the
aggregate Exercise Price as set forth above (“Warrant Share Delivery Date”).  This Warrant shall be deemed to have been
exercised on the date the Exercise Price is received by the Company.  The Warrant Shares shall be deemed to have
been issued, and Holder or any other person so designated to be named therein
shall be deemed to have become a holder of record of such shares for all
purposes, as of the date the Warrant has been exercised by payment to the
Company of the Exercise Price and all taxes required to be paid by the Holder,
if any, pursuant to Section 2(d)(vi) prior to the issuance of such shares, have
been paid.

 3
 

iii.            Delivery of New Warrants Upon
Exercise.  If this Warrant shall have
been exercised in part, the Company shall, at the request of a Holder and upon
surrender of this Warrant certificate, at the time of delivery of the
certificate or certificates representing Warrant Shares, deliver to Holder a
new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant
Shares called for by this Warrant, which new Warrant shall in all other
respects be identical with this Warrant.

iv.            Rescission Rights.  If the Company fails to cause its transfer
agent to transmit to the Holder a certificate or certificates representing the
Warrant Shares pursuant to this Section 2(d) by the Warrant Share Delivery
Date, then the Holder will have the right to rescind such exercise.

v.             No Fractional Shares or Scrip.  No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant.  As to any fraction of a share which Holder
would otherwise be entitled to purchase upon such exercise, the Company shall
at its election, either pay a cash adjustment in respect of such final fraction
in an amount equal to such fraction multiplied by the Exercise Price or round
up to the next whole share.

vi.            Charges, Taxes and Expenses.  Issuance of certificates for Warrant Shares
shall be made without charge to the Holder for any issue or transfer tax or
other incidental expense in respect of the issuance of such certificate, all of
which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder; provided, however, that in the event
certificates for Warrant Shares are to be issued in a name other than the name
of the Holder, this Warrant when surrendered for exercise shall be accompanied
by the Assignment Form attached hereto duly executed by the Holder; and the
Company may require, as a condition thereto, the payment of a sum sufficient to
reimburse it for any transfer tax incidental thereto.

vii.           Closing of Books.  The Company will not close its shareholder
books or records in any manner which prevents the timely exercise of this
Warrant, pursuant to the terms hereof.

Section 3.               Certain Adjustments.

a)             Stock Dividends and Splits.  If the Company, at any time while this
Warrant is outstanding: (A) pays a stock dividend or otherwise make a
distribution or distributions on shares of its Common Stock or any other equity
or equity equivalent securities payable in shares of Common Stock (which, for
avoidance of doubt, shall not include any shares of Common Stock issued by the
Company upon exercise of this Warrant, any other warrant or any option), (B)
subdivides outstanding shares of Common Stock into a larger number of shares,
(C) combines (including by way of reverse stock split) outstanding shares of
Common Stock into a smaller number of shares, or (D) issues by reclassification
of shares of the Common Stock any shares of capital stock of the Company, then
in each case the Exercise Price shall be multiplied by a fraction of which

 4
 

the numerator shall be
the number of shares of Common Stock (excluding treasury shares, if any)
outstanding immediately before such event and of which the denominator shall be
the number of shares of Common Stock outstanding immediately after such event
and the number of shares issuable upon exercise of this Warrant shall be
proportionately adjusted.  Any adjustment
made pursuant to this Section 3(a) shall become effective immediately after the
record date for the determination of shareholders entitled to receive such
dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision, combination or re-classification.

b)            Adjustment for Issuance of Shares
of Common Stock Below Exercise Price. 
From the date hereof until 12 months after the date hereof (the “Adjustment
Period”), the Exercise Price shall be subject to adjustment from time to
time as provided in this Section 3(b).

i.              If
during the Adjustment Period, the Company issues or sells, or in accordance
with this Section 3(b) is deemed to have issued or sold, any shares of
Common Stock (excluding Excluded Securities) for a consideration per share (the
“New Securities Issuance Price”)
less than a price (the “Applicable
Price”) equal to the Exercise Price in effect immediately prior to
such time, then immediately after such issue or sale, the Exercise Price then
in effect shall be reduced to an amount equal to the New Securities Issuance
Price.

ii.             For
purposes of determining the adjusted Exercise Price under Section 3(b) hereof,
the following will be applicable:

(A)          Issuance of Rights or Options.
If the Company in any manner grants or sells any Options and the lowest price
per share for which one share of Common Stock is issuable upon the exercise of
any such Option or upon conversion, exchange or exercise of any Convertible
Securities issuable upon exercise of such Option is less than the Applicable
Price, then such share of Common Stock shall be deemed to be outstanding and to
have been issued and sold by the Company at the time of the granting or sale of
such Option for such price per share. For purposes of this
Section 3(b)(ii)(A), the “lowest price per share for which one share of
Common Stock is issuable upon the exercise of any such Option or upon
conversion, exchange or exercise of any Convertible Securities issuable upon
exercise of such Option” shall be equal to the sum of the lowest amounts of
consideration (if any) received or receivable by the Company with respect to
any one share of Common Stock upon granting or sale of the Option, upon
exercise of the Option and upon conversion, exchange or exercise of any
Convertible Security issuable upon exercise of such Option. No further
adjustment of the Exercise Price shall be made upon the actual issuance of such
Common Stock or of such Convertible Securities upon the exercise of such
Options or upon the actual issuance of such Common Stock upon conversion,
exchange or exercise of such Convertible Securities.  “Convertible Securities” means any
evidence of indebtedness, shares or securities, in each case convertible into
or exchangable for Common Stock.  “Options”
means rights, options or

 5
 

warrants to subscribe for, purchase or otherwise
acquire shares of Common Stock or Convertible Securities.

(B)           Issuance of Convertible Securities.
If the Company in any manner issues or sells any Convertible Securities and the
lowest price per share for which one share of Common Stock is issuable upon
such conversion, exchange or exercise thereof is less than the Applicable
Price, then such share of Common Stock shall be deemed to be outstanding and to
have been issued and sold by the Company at the time of the issuance or sale of
such Convertible Securities for such price per share. For the purposes of this
Section 3(b)(ii)(B), the “lowest price per share for which one share of Common
Stock is issuable upon such conversion, exchange or exercise” shall be equal to
the sum of the lowest amounts of consideration (if any) received or receivable
by the Company with respect to any one share of Common Stock upon the issuance
or sale of the Convertible Security and upon the conversion, exchange or
exercise of such Convertible Security. No further adjustment of the Exercise
Price shall be made upon the actual issuance of such Common Stock upon
conversion, exchange or exercise of such Convertible Securities, and if any
such issue or sale of such Convertible Securities is made upon exercise of any
Options for which adjustment of the Exercise Price had been or are to be made
pursuant to other provisions of this Section 3(b)(ii), no further adjustment of
the Exercise Price shall be made by reason of such issue or sale.

(C)           Change in Option Price or
Conversion Rate. If the purchase or exercise price provided for in any
Options, or the additional consideration, if any, payable upon the issue,
conversion, exchange or exercise of any Convertible Securities, or the rate at
which any Convertible Securities are convertible into or exchangeable or
exercisable for Common Stock changes at any time, the Exercise Price in effect
at the time of such change shall be adjusted to the Exercise Price which would
have been in effect at such time had such Options or Convertible Securities
provided for such changed purchase price, additional consideration or changed
conversion rate, as the case may be, at the time initially granted, issued or
sold. For purposes of this Section 3(b)(ii)(C), if the terms of any Option or
Convertible Security that was outstanding as of the Closing Date are changed in
the manner described in the immediately preceding sentence, then such Option or
Convertible Security and the Common Stock deemed issuable upon exercise,
conversion or exchange thereof shall be deemed to have been issued as of the
date of such change.  No adjustment shall
be made if such adjustment would result in an increase of the Exercise Price
then in effect.  Notwithstanding the
foregoing, no adjustment shall be made to the Exercise Price of this Warrant
due to anti-dilution adjustments made to securities outstanding as of the date
hereof as a result of the issuance of Securities pursuant to the Transaction
Documents.

(D)          Calculation of Consideration
Received. In case any Option is issued in connection with the issue or sale
of other securities of the Company, together comprising one integrated
transaction in which no specific consideration is allocated to such Options by
the parties thereto, the Options will be deemed to have been issued for a
consideration of $0.01. If any Common Stock, Options or

 6
 

Convertible Securities are issued or sold or deemed to
have been issued or sold for cash, the consideration received therefor will be
deemed to be the gross amount received by the Company therefor. If any Common
Stock, Options or Convertible Securities are issued or sold for a consideration
other than cash, the amount of the consideration other than cash received by
the Company will be the fair value of such consideration, except where such consideration
consists of marketable securities, in which case the amount of consideration
received by the Company will be the arithmetic average of the closing sale
prices of such securities during the ten (10) consecutive trading days
ending on the date of receipt of such securities. The fair value of any
consideration other than cash or securities will be determined jointly by the
Company and the holders of at least a majority in interest of the Warrants then
outstanding.

(E)           Exceptions to Adjustment of Exercise
Price. Notwithstanding the foregoing, no adjustment will be made under this
Section 3(b) in respect of Excluded Securities.   “Excluded Securities” means the
issuance of (a) shares of Common Stock or options to employees, officers or
directors of, or consultants to, the Company pursuant to any stock option
agreement, stock option plan or equity incentive plan duly adopted by a
majority of the non-employee members of the Board of Directors of the Company
or a majority of the members of a committee of non-employee directors  established for such purpose (for purposes of clarity, the
issuance of shares of Common Stock upon exercise of options granted pursuant to
a stock option agreement, stock option plan or equity incentive plan subsequent
to the date hereof shall also be Excluded Securities), (b) securities upon the
exercise or exchange of or conversion of (i) any Securities issued in
connection with the Purchase Agreement; (ii) securities to a registered
broker-dealer in connection with the transactions contemplated by the Purchase
Agreement; and/or (iii) other securities or rights exercisable or exchangeable
for or convertible into shares of Common Stock which are issued and outstanding
on the date of the Purchase Agreement, provided that such securities have not
been amended since the date of the Purchase Agreement (other than on a
non-discretionary basis pursuant to the pre-existing anti-dilution provisions
thereof) to increase the number of such securities or to decrease the exercise,
exchange or conversion price of any such securities, (c) securities issued
pursuant to acquisitions or strategic transactions approved by  a majority of the disinterested directors, provided any
such issuance shall only be to a Person which is, itself or through its subsidiaries,
an operating company in a business synergistic with the business of the Company
and in which the Company receives benefits in addition to the investment of
funds, but shall not include a transaction in which the Company is issuing
securities primarily for the purpose of raising capital or to an entity whose
primary business is investing in securities, (d) shares of Common Stock or
other securities issued in connection with any stock split, stock dividend or
recapitalization of the Company (subject to Section 3(a) hereof), and (e)
shares of Common Stock or other securities issued in connection with any
registered primary public offering.

 7
 

c)             Calculations.  All calculations under this Section 3 shall
be made to the nearest cent or the nearest 1/100th of a share, as the case may
be.  For purposes of this Section 3, the
number of shares of Common Stock deemed to be issued and outstanding as of a
given date shall be the sum of the number of shares of Common Stock (excluding
treasury shares, if any) issued and outstanding.

d)            Voluntary Adjustment By 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.

e)             Notice to Holders.

i.              Adjustment to Exercise Price.  Whenever the Exercise Price is adjusted
pursuant to any provision of this Section 3, the Company shall promptly mail to
each Holder a notice setting forth the Exercise Price after such adjustment and
setting forth a brief statement of the facts requiring such adjustment.

ii.             Notice to Allow Exercise by
Holder.  If (A) the Company shall
declare a dividend (or any other distribution in whatever form) on the Common
Stock; (B) the Company shall declare a special nonrecurring cash dividend on or
a redemption of the Common Stock; (C) the Company shall authorize the granting
to all holders of the Common Stock rights or warrants to subscribe for or
purchase any shares of capital stock of any class or of any rights; (D) the
approval of any shareholders of the Company shall be required in connection
with any reclassification of the Common Stock, any consolidation or merger to
which the Company is a party, any sale or transfer of all or substantially all
of the assets of the Company, of any compulsory share exchange whereby the
Common Stock is converted into other securities, cash or property; (E) the
Company shall authorize the voluntary or involuntary dissolution, liquidation
or winding up of the affairs of the Company; then, in each case, the Company
shall cause to be mailed to the Holder at its last address as it shall appear
upon the Warrant Register of the Company, at least 20 calendar days prior to
the applicable record or effective date hereinafter specified, a notice stating
(x) the date on which a record is to be taken for the purpose of such dividend,
distribution, redemption, rights or warrants, or if a record is not to be
taken, the date as of which the holders of the Common Stock of record to be
entitled to such dividend, distributions, redemption, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of the Common Stock
of record shall be entitled to exchange their shares of the Common Stock for
securities, cash or other property deliverable upon such reclassification,
consolidation, merger, sale, transfer or share exchange; provided that the
failure to mail such notice or any defect therein or in the mailing thereof
shall not affect the validity of the corporate action required to be specified
in such notice.  The Holder is entitled
to exercise this Warrant during the 20-day period commencing on the date of
such notice to the effective date of the event triggering such notice.

 8
 

Section 4.               Transfer of Warrant.

a)             Transferability.  Subject to compliance with any applicable
securities laws and the conditions set forth in Section 4(d) hereof, this
Warrant and all rights hereunder (including, without limitation, any
registration rights) are transferable, in whole or in part, upon surrender of
this Warrant at the principal office of the Company or its designated agent,
together with a written assignment of this Warrant substantially in the form
attached hereto duly executed by the Holder or its agent or attorney and funds
sufficient to pay any transfer taxes payable upon the making of such
transfer.  Upon such surrender and, if
required, such payment, the Company shall execute and deliver a new Warrant or
Warrants in the name of the assignee or assignees and in the denomination or
denominations specified in such instrument of assignment, and shall issue to
the assignor a new Warrant evidencing the portion of this Warrant not so
assigned, and this Warrant shall promptly be cancelled.  A Warrant, if properly assigned, may be
exercised by a new holder for the purchase of Warrant Shares without having a
new Warrant issued.

b)            New Warrants.  This Warrant may be divided or combined with
other Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued, signed by the Holder or its agent or
attorney.  Subject to compliance with
Section 4(a), as to any transfer which may be involved in such division or
combination, the Company shall execute and deliver a new Warrant or Warrants in
exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice.

c)             Warrant Register.  The Company shall register this Warrant, upon
records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time.  The Company may deem and treat the registered
Holder of this Warrant as the absolute owner hereof for the purpose of any
exercise hereof or any distribution to the Holder, and for all other purposes,
absent actual notice to the contrary.

d)            Transfer Restrictions.  If, at the time of the surrender of this
Warrant in connection with any transfer of this Warrant, the transfer of this
Warrant shall not be registered pursuant to an effective registration statement
under the Securities Act and under applicable state securities or blue sky
laws, the Company may require, as a condition of allowing such transfer (i)
that the Holder or transferee of this Warrant, as the case may be, furnish to
the Company a written opinion of counsel (which opinion shall be in form,
substance and scope customary for opinions of counsel in comparable
transactions) to the effect that such transfer may be made without registration
under the Securities Act and under applicable state securities or blue sky
laws, (ii) that the Holder or transferee execute and deliver to the Company an
investment letter in form and substance acceptable to the Company and (iii)
that the transferee be an “accredited investor” as defined in Rule 501(a)(1),
(a)(2), (a)(3), (a)(7), or (a)(8) promulgated under the Securities Act or a “qualified
institutional buyer” as defined in Rule 144A(a) under the Securities Act.

 9
 

Section 5.               Miscellaneous.

a)             No Rights as Shareholder Until
Exercise.  This Warrant does not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof as set forth in Section 2(d)(ii).

b)            Loss, Theft, Destruction or
Mutilation of Warrant.  The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any
stock certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which, in
the case of the Warrant, shall not include the posting of any bond), and upon
surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like
tenor and dated as of such cancellation, in lieu of such Warrant or stock
certificate.

c)             Saturdays, Sundays, Holidays,
etc.  If the last or appointed day
for the taking of any action or the expiration of any right required or granted
herein shall not be a Business Day, then such action may be taken or such right
may be exercised on the next succeeding Business Day.

d)            Authorized Shares.

The Company covenants
that during the period the Warrant is outstanding, it will reserve from its
authorized and unissued Common Stock a sufficient number of shares to provide
for the issuance of the Warrant Shares upon the exercise of any purchase rights
under this Warrant.  The Company further
covenants that its issuance of this Warrant shall constitute full authority to
its officers who are charged with the duty of executing stock certificates to
execute and issue the necessary certificates for the Warrant Shares upon the
exercise of the purchase rights under this Warrant.  The Company will take all such reasonable
action as may be necessary to assure that such Warrant Shares may be issued as
provided herein without violation of any applicable law or regulation, or of
any requirements of the Trading Market upon which the Common Stock may be
listed.

Except and to the extent
as waived or consented to by the Holder, the Company shall not by any action,
including, without limitation, amending its articles of incorporation or
through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid
or seek to avoid the observance or performance of any of the terms of this
Warrant, but will at all times in good faith assist in the carrying out of all
such terms and in the taking of all such actions as may be necessary or
appropriate to protect the rights of Holder as set forth in this Warrant
against impairment.  Without limiting the
generality of the foregoing, the Company will (a) not increase the par value of
any Warrant Shares above the amount payable therefor upon such exercise
immediately prior to such increase in par value, (b) take all such action as
may be necessary or appropriate in order that the Company may validly and
legally issue fully paid and nonassessable Warrant Shares upon the exercise of
this Warrant, and (c) use commercially reasonable efforts to obtain

 10
 

all such authorizations, exemptions or consents from
any public regulatory body having jurisdiction thereof as may be necessary to
enable the Company to perform its obligations under this Warrant.

Before taking any action
which would result in an adjustment in the number of Warrant Shares for which
this Warrant is exercisable or in the Exercise Price, the Company shall obtain
all such authorizations or exemptions thereof, or consents thereto, as may be
necessary from any public regulatory body or bodies having jurisdiction
thereof.

e)             Jurisdiction.  All questions concerning the construction,
validity, enforcement and interpretation of this Warrant shall be determined in
accordance with the provisions of the Purchase Agreement.

f)             Restrictions.  The Holder acknowledges that the Warrant
Shares acquired upon the exercise of this Warrant, if not registered, will have
restrictions upon resale imposed by state and federal securities laws.

g)            Nonwaiver and Expenses.  No course of dealing or any delay or failure
to exercise any right hereunder on the part of Holder shall operate as a waiver
of such right or otherwise prejudice the Company’s or the Holder’s rights,
powers or remedies, notwithstanding the fact that all rights hereunder
terminate on the Termination Date.  If
the Company or a Holder willfully and knowingly fails to comply with any
provision of this Warrant, which results in any material damages to the Holder
or Company (as the case may be), the breaching party shall pay to the other
party such amounts as shall be sufficient to cover any costs and expenses
including, but not limited to, reasonable attorneys’ fees, including those of
appellate proceedings, incurred by the non-breaching party in collecting any
amounts due pursuant hereto or in otherwise enforcing any of its rights, powers
or remedies hereunder.

h)            Notices.  Any notice, request or other document
required or permitted to be given or delivered to the Holder by the Company
shall be delivered in accordance with the notice provisions of the Purchase
Agreement.

i)              Limitation of Liability.  No provision hereof, in the absence of any
affirmative action by Holder to exercise this Warrant to purchase Warrant
Shares, and no enumeration herein of the rights or privileges of Holder, shall
give rise to any liability of Holder for the purchase price of any Common Stock
or as a shareholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

j)              Remedies.  Holder, in addition to being entitled to
exercise all rights granted by law, including recovery of damages, will be
entitled to seek specific performance of its rights under this Warrant.  The Company agrees that monetary damages
would not be adequate compensation for any loss incurred by reason of a breach by
it of the provisions of this Warrant and hereby agrees to waive and not to
assert the defense in any action for specific performance that a remedy at law
would be adequate.

 11
 

k)             Successors and Assigns.  Subject to applicable securities laws, this
Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors of the Company and the successors
and permitted assigns of Holder.  The
provisions of this Warrant are intended to be for the benefit of all Holders
from time to time of this Warrant and shall be enforceable by any such Holder
or holder of Warrant Shares.

l)              Amendment.  This Warrant may be modified or amended or
the provisions hereof waived with the written consent of the Company and the
Holder.

m)            Severability.  Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Warrant.

n)            Headings.  The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

EXHIBIT
C

SECURITY
AGREEMENT AND FORM OF UCC FINANCING STATEMENT

THIS SECURITY AGREEMENT (this “Agreement”) is entered into effective as of
April 20, 2007 by MedicalCV, Inc., a Minnesota corporation having its principal
offices at 9725 South Robert Trail, Inver Grove Heights, Minnesota 55077 (the “Debtor”), in favor
of the parties listed on Exhibit 1 attached hereto (the “Secured Parties”).

Pursuant to the Secured Note Purchase Agreement
dated of even date herewith by and among the Debtor and the Secured Parties
(the “Note Purchase
Agreement”), and for good and valuable consideration, Debtor
hereby agrees for the benefit of the Secured Parties as follows:

1.             SECURITY
INTEREST AND COLLATERAL

Debtor hereby grants the Secured Parties a first
priority security interest in all of the Debtor’s right, title, and interest in
and to the property described below (collectively referred to as the “Security
Interest”) as a security for the payment and performance of certain Secured
Promissory Notes issued pursuant to the Note Purchase Agreement by Debtor in
favor of the Secured Parties, respectively (the “Notes”), together with accrued but
unpaid interest thereon, and costs of collection, including reasonable
attorneys’ fees, and all other obligations of Debtor to Secured Parties of any
nature whatsoever (all known collectively as the “Obligations”).  The Security Interest shall attach to all
assets of the Debtor of every kind and every description, whether now owned or
hereafter acquired, and all proceeds thereof (the “Collateral”),
which shall include without limitation the following:

General Intangibles: All general intangibles of the Debtor,
whether now owned or hereafter acquired, including without limitation all
present and future patents and patent applications in all jurisdictions and
territories (foreign and domestic), together with all divisions, reissues,
reexaminations, term extensions, and continuations associated therewith,
copyrights, trademarks, service marks, trade names, trade secrets, know-how,
processes, and all licenses or agreements of any kind or nature pursuant to
which the Debtor possesses, uses, or has authority to possess or use any of the
foregoing, customer or supplier lists and contracts, manuals, operating
instructions, permits, franchises, the right to use the Debtor’s name and the
goodwill of the Debtor’s business.

Inventory: All inventory of the Debtor, as that term is
defined in the Uniform Commercial Code, whether now owned or hereafter acquired
or in which the Debtor obtains rights, whether consisting of whole goods, spare
parts or components, supplies or materials whether acquired, held or furnished
for sale, for lease or under contracts or for manufacture or processing, and
wherever located;

Equipment: All equipment of the Debtor, whether now
owned or hereafter acquired, including all present and future machinery,
vehicles, furniture, fixtures, office and recordkeeping equipment, parts,
tools, supplies and all other goods (except inventory) used or bought for use
by the Debtor for any business or enterprise and including specifically
(without limitation) all accessions thereto, all substitutions and replacements
thereof, and all like or similar property now owned or hereafter acquired by
the Debtor, and all of which is owned by the Debtor; and

Receivables: Each and every right of the Debtor to the
payment of money, whether such right to payment now exists or hereafter arises,
whether such right to payment arises out of a sale, lease or other disposition
of goods or other property, out of a rendering of services, or of a loan, out
of the overpayment 

of taxes or other liabilities, or any other
transaction or event, whether such right to payment is created, generated or
earned by the Debtor or by some other person who subsequently transfers his,
her or its interest to the Debtor, whether such right to payment is or is not
already earned by performance, and howsoever such right to payment may be
evidenced, together with all other rights and interests (including all liens
and other security interests) which the Debtor may at any time have by law or
agreement against any account debtor or other person obligated to make such
payment or against any property of such account debtor or other persons
including, but not limited to, all present and future accounts, contract
rights, chattel paper, bonds, notes and other debt instruments, and rights to
payment in the nature of general intangibles.

The Collateral shall include (i) all substitutes and
replacements for and proceeds of any and all of the foregoing property, and in
the case of all tangible Collateral, all accessions, accessories, attachments,
parts, equipment and repairs now or hereafter attached or affixed to or use in
connection with any such goods and (ii) all warehouse receipts, bills of lading
and other documents of title now or hereafter covering such goods.

2.             REPRESENTATIONS, WARRANTIES AND
COVENANTS

Debtor represents, warrants,
and covenants that:

(a)           Existence
and Authority.  Debtor is a corporation, duly organized,
validly existing and in good standing under the laws of the State of Minnesota,
having full power and authority to make and deliver this Agreement.  The correct name of the Debtor is set forth
at the beginning of this Agreement. 
Debtor’s principal place of business and president are located at the
address as set forth in the opening paragraph of this Agreement.  The Debtor covenants with the Secured Parties
that it will not change its name, principal executive office, its mailing
address, its registered agent or its type or jurisdiction of organization
without providing each Secured Party ten days prior written notice.

(b)           Title;  Maintenance. 
Debtor is and will be, the owner of the Collateral, free of all liens,
encumbrances and security interests except for the security interests created
hereby or any interest specifically consented to in writing by the Secured
Parties.  The Debtor will keep the Collateral in good order and repair.

(c)           Financing Statements.  The
Debtor authorizes the Secured Parties to file all financing statements,
documents or records, and any amendments thereto, in such form as the Secured
Parties deem necessary to perfect their Security Interest.

(e)           No Encumbrances.  The
debtor will not pledge, lien or in any way encumber the Collateral without the
prior written consent of the Secured Parties.

(f)            Negative Covenants.  Debtor will not at any time
without the Secured Parties’ prior written consent (i) other than in the
ordinary course of its business, sell, lease or otherwise dispose of or
transfer any of the Collateral, (ii) merge or consolidate with another entity
or (iii) change its state of organization or location.

(g)           Inspections.  Debtor grants the Secured
Parties an irrevocable license to enter Debtor’s business location during
normal business hours upon giving reasonable notice to Debtor to (i) account
for and inspect all Collateral, (ii) verify Debtor’s compliance with this
Agreement and (iii) examine and copy Debtor’s books and records relating to the
Collateral.

 2
 

3.             DEFAULT,
REMEDIES AND ACTIONS OF SECURED PARTIES

(a)           Defaults. 
Debtor shall be in default under this Agreement upon the happening of
any of the Events of Default as defined in the Note Purchase Agreement.

(b)           Remedies.  In the event of a default (i) the Secured
Parties shall have the right, at their option and without demand or notice, to
declare all or any part of the Obligations immediately due and payable (to the
extent that the Obligations are not already by their terms immediately due and
payable without any action on the part of the Secured Parties);  (ii) the Secured Parties may exercise, in
addition to the rights and remedies granted hereby, all of the rights and
remedies of a secured party under the Uniform Commercial Code as adopted in
Minnesota or under any other applicable law (the “UCC”); 
(iii) the Secured Parties may exercise their rights to possess, transfer
and dispose of the Collateral;  (iv) the
Secured Parties may request, and Debtor will agree, to segregate and keep the
Collateral in trust for the Secured Parties in good order and repair and will
immediately deliver the Collateral at a place specified by the Secured Parties
together with all related documents;  and
(v) Debtor agrees to pay all costs and expenses incurred by the Secured Parties
in the collection of any of the Obligations or the enforcement of any of the
Secured Parties’ rights.

(c)           Sale of Collateral.  Upon any default, Debtor agrees
that ten (10) or more calendar days prior written notice is commercially
reasonable notice of any public or private sale or transfer of Collateral by
the Secured Parties.  Upon any default,
Debtor irrevocably grants the Secured Parties a license to enter upon Debtor’s
premises without notice or judicial order to take possession of the
Collateral.  The Secured Parties are
hereby granted a license or other right to use, without charge, all of the
Debtor’s property, including, without limitation, all of the Debtor’s labels,
trademarks, copyrights, patents and advertising matter or any property of a
similar nature, as it pertains to the Collateral, in completing production of
advertising for sale and selling any Collateral, and Debtor’s rights under all
licenses shall inure to the Secured Parties’ benefit until the Obligations are
paid in full.

(d)           Power of
Attorney.  Debtor
grants the Secured Parties an irrevocable Power of Attorney to (i) execute or
endorse on Debtor’s behalf any checks, financing statements, instruments,
certificates of title and statements of origin pertaining to the
Collateral;  (ii) supply any omitted
information and correct errors in any documents between the Secured Parties and
Debtor;  (iii) initiate and settle any
insurance claims pertaining to the Collateral; and (iv) do anything to preserve
and protect the Collateral and the Secured Parties’ rights and interests
therein.

(e)           Costs and Expenses.  The
Debtor will pay or reimburse the Secured Parties on demand for all
out-of-pocket expenses (including in each case all filing, recording fees,
taxes and all reasonable fees and expenses of counsel and of any experts and
agents) incurred by the Secured Parties in connection with the creation,
perfection, protection, satisfaction or foreclosure of the Collateral and the
preparation, administration, continuance, amendment or enforcement of this
Agreement, and all such costs and expenses shall be part of the Obligations
secured by the Collateral.

(f)            Defense.  The
Debtor will at its own expense, and using its commercially reasonable efforts
and sound business judgment, protect and defend the Collateral against all
claims or demands of all persons other than the Secured Parties that would
cause material harm to the Secured Parties.

(j)            Waiver of Notice and Hearing.  The Debtor hereby waives all
rights to a judicial hearing of any kind prior to the exercise by the Secured Parties
of their rights to possession of the 

 3
 

Collateral without judicial process or of their rights
to replevin, attach or levy upon the Collateral without prior notice or
hearing.  In the event that a
pre-judgment order for replevin is obtained, Debtor waives any requirement of
the Secured Parties to post bond.  DEBTOR HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN
ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY.

(k)           Joint
Action of the Secured Parties.  With
respect to any action taken in connection with this Agreement, the Secured
Parties shall act in accordance with and under the directions of the Secured
Parties holding a majority-in-interest of the outstanding Principal Amount of
the Notes, or a designee appointed thereby. 
If the Secured Parties determine to act through a single Secured Party
or other designee, the Secured Parties shall so inform the Debtor in writing.  Action thereafter taken by such Secured Party
or designee shall be deemed to be taken on behalf of all Secured Parties.

4.             Miscellaneous.

(a)           No Waiver;  Cumulative Remedies.  No failure delay on the part of
the Secured Parties to exercise any right, power or remedy under this Agreement
shall operate as a waiver thereof.  In
addition, no single or partial exercise of any right, power or remedy shall
preclude any other or further exercise thereof or the exercise of any other
right, power or remedy under this Agreement. 
The remedies provided for in this Agreement are cumulative and not
exclusive of any remedies provided by law.

(b)           Law Governing and Construction.  The validity, construction and
enforceability of this Agreement shall be governed by the laws of the State of
Minnesota, without giving effect to conflict of laws principles thereof.

(c)           Continuing Interest.  This Agreement shall create a continuing
security interest in the Collateral and shall remain in full force and effect
until the satisfaction in full of all of the Obligations.  At such time as Debtor shall completely
satisfy all of the Obligations, this Agreement shall terminate and the Secured
Parties shall execute and deliver to Debtor all instruments as may be necessary
to re-vest in Debtor full title to the Collateral or evidence such termination.

(d)           Severability.  The
provisions of this Agreement are severable. 
If any clause or provision is held invalid and unenforceable in whole or
in part in any jurisdiction, then such invalidity or unenforceability shall
affect only such clause or provision, or part thereof, in such jurisdiction,
and shall not in any manner affect such clause or provision in any other
jurisdiction, or any other clause or provision of this Agreement in any
jurisdiction.

(e)           Modifications.  Any
modifications or termination of this Agreement may be made only by a writing
signed by all of the parties.

(f)            Binding
Effect.  This Agreement and the Security Interest
granted hereby, is binding upon Debtor, its successors and assigns, and shall
inure to the benefit of and be enforceable by the Secured Parties and each of
their successors and assigns.

or supplier lists and contracts, manuals, operating instructions, permits,
franchises, the right to use the Debtor’s name and the goodwill of the Debtor’s
business.

Inventory:
All inventory of the Debtor, as that term is defined in the Uniform Commercial
Code, whether now owned or hereafter acquired or in which the Debtor obtains
rights, whether consisting of whole goods, spare parts or components, supplies

whether such right to payment is created, generated or earned by the Debtor or

with all other rights and interests (including all liens and other security
interests) which the Debtor may at any time have by law or agreement against

LEGAL OPINION

April 20, 2007

To:                              Holder
under the Secured Note Purchase Agreement dated April 20, 2007

Ladies and Gentlemen:

We have acted as counsel to MedicalCV, Inc., a
Minnesota corporation (the “Company”) in connection with a Secured Note
Purchase Agreement (the “SNPA”) dated as of April 20, 2007 between the Company
and an affiliate of Whitebox Advisors, LLC (“Whitebox”).  This opinion letter is delivered to you at
the Company’s request under Section 7.1(g) of the SNPA.  All capitalized terms used, and not otherwise
defined, in this opinion letter have the meanings given to them in the SNPA.

In connection with
this opinion, we have reviewed drafts of the following documents (collectively,
the “Transaction Agreements”), each of which is dated as of April 20, 2007,
unless otherwise described:

1.                                       the
Secured Note Purchase Agreement;

2.                                       the
Secured Promissory Note;

3.                                       the
Security Agreement; and

4.                                       the
Closing Warrant.

For purposes of this opinion letter we have reviewed
such documents and made such other investigation as we have deemed
appropriate.  As to certain matters of
fact material to the opinions expressed in this letter, we have relied on the
representations made in the Transaction Agreements and certificates of officers
of the Company.  We have not independently
established the facts so relied on.

As used in this opinion letter, the term “Collateral”
has the meaning given in the Security Agreement.  References in this opinion letter to the
“UCC” mean the Uniform Commercial Code as in effect in the State of Minnesota
on the date hereof.  As used in this
opinion letter, the phrases “to our knowledge,” “known to us” or similar words
mean the actual, conscious awareness on the date of this letter of Briggs and
Morgan, Professional Association, the lawyers in our firm who have been
actively involved in the negotiation or preparation of the Transaction
Agreements or this letter.

We assume with your permission and without
investigation: (i) the due authorization, execution and delivery of the
Transaction Agreements by all parties thereto other than the Company, (ii) the
validity, binding effect and enforceability under applicable law of the
Transaction Agreements against the parties thereto other than the Company,
(iii) the authenticity of all documents submitted to us as originals, (iv) the
genuineness of all signatures; (v) the legal capacity of natural persons, (vi)
the conformity to originals of all documents submitted to us as copies and the
authenticity of the originals of such copies, and (vii) that Whitebox has given
value and the Company has rights in the Collateral, in each case within the
meaning of Section 9 of the UCC, and (viii) that the description of the
Collateral reasonably identifies what is described, within the meaning of
Section 9 of the UCC.

Based upon the
assumptions set forth above and the other limitations and qualifications set
forth below, we are of the opinion that:

1.             The
Company is duly incorporated and is validly existing as a corporation in good
standing under the laws of the State of Minnesota.

2.             The
Company has corporate power and authority to conduct its business as described
in the Company’s SEC Filings and to enter into and perform its obligations
under the Transaction Agreements.

3.             The
Company is duly qualified to transact business and is in good standing in any
jurisdiction in which it owns or leases substantial property or in which the
conduct of its business requires such qualification, except where the failure
to do so would not, individually or in the aggregate, have a material adverse
effect on the properties, assets, operations, business or condition (financial
or otherwise) of the Company.

4.             To
our knowledge, all of the outstanding shares of the Company’s capital stock
have been duly authorized and validly issued, are fully paid and nonassessable
and have been issued in compliance with the registration and qualification
requirements of federal and state securities laws or were issued pursuant to an
available exemption from the registration and qualification requirements of
applicable federal and state securities laws.

5.             Pursuant
to a Securities Purchase Agreement dated October 13, 2006, Potomac Capital
Partners LP, Potomac Capital International Ltd. and Pleiades Investment
Partners-R LP were granted participation rights in future financings of the
Company, which participation rights have been validly waived by said parties in
connection with the transaction contemplated by the Transaction
Agreements.  Otherwise, to our knowledge,
no stockholder of the Company or any other person has any preemptive right,
right of first refusal or other similar right to subscribe for or purchase the
Company’s securities arising (a) by operation of the Articles of Incorporation
or Bylaws of the Company or the Minnesota Business Corporation Act or (b)
otherwise.

6.             The
Transaction Agreements have been duly authorized, executed and delivered by,
and are valid and binding agreements of, the Company, enforceable in accordance
with their terms, except as rights to indemnification thereunder may be limited
by applicable law and except as the enforcement thereof may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
relating to or affecting creditors’ rights generally or by general equitable
principles.

7.             The
Notes, Warrants and Warrant Shares have been duly authorized for issuance and
sale pursuant to the Transaction Agreements and, when issued and delivered by
the Company pursuant to payment of the consideration set forth in the
Transaction Agreements, will be validly issued, fully paid and nonassessable.

8.             The
provisions of the Security Agreement are sufficient to create in favor of
Whitebox the security interest, as described therein, in all right, title and
interest of the Company in those items and types of Collateral described in the
Security Agreement in which a security interest may be created under Section 9
of the UCC.  The filing of a UCC-1
financing statement (within the meaning of Section 9-502(a) of the UCC) with
the Office of the Secretary of the State of Minnesota is sufficient to perfect
a security interest in the Collateral, to the extent that a security interest
may be perfected by filing a financial statement under the UCC in such office.

9.             No
governmental approvals or filings are required for the execution and delivery
of the Transaction Agreements on behalf of the Company, the payment of the
Company’s obligations under the Transaction Agreements, or the creation by the
Company of the security interests created by the Transaction Agreements, except
for the filings necessary to perfect the liens granted under the Transaction
Agreements.

10.           To
our knowledge, the Company is not in violation of its Articles of Incorporation
or Bylaws or any law, administrative regulation or administrative or court
decree applicable to the Company and is not in default in the performance or
observance of any obligation, agreement, covenant or condition contained in any
material existing instrument or agreement.

11.           The
execution and delivery of the Transaction Agreements by the Company and the
performance by the Company of its obligations thereunder (a) will not result in
any violation of the provisions of the Articles of Incorporation or Bylaws of
the Company; (b) will not constitute a breach of, or a default under, or result
in the creation or imposition of, any lien, charge or encumbrance upon any
property or assets of the Company pursuant to, to our knowledge, any existing
instrument or agreement of the Company; and (c) to our knowledge, will not
result in any violation of any law, administrative regulation or administrative
or court decree applicable to the Company.

12.           The
Company is not, and, assuming the Company does not invest its assets in any
“investment securities” as defined in Section 3(a)(2) of the Investment Company
Act of 1940, as amended (the “1940 Act”), will not become, as a result of the
consummation of the transactions contemplated by the Transaction Agreements and
the receipt of payment for the Notes, Warrants 

or, if issued upon
exercise of the Warrants, the Warrant Shares thereunder, an “investment
company” as defined in the 1940 Act, and the rules and regulations promulgated
thereunder.

Our opinions are
subject to the following additional qualifications:

(a)           Our
opinions are limited to the law of the State of Minnesota and the federal
securities laws of the United States of America.

(b)           The
enforceability of the Transaction Agreements is subject to and may be limited
by (i) the effect of any applicable bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting the rights and remedies of creditors
generally, (ii) general principles of equity and (iii) applicable statutes of
limitation.

(c)           We
express no opinion with respect to the validity and enforceability of (i)
indemnification provisions, rights of contribution and exculpatory provisions
to the extent they may be limited on public policy grounds or subject to
securities laws; (ii) broadly stated powers of attorney; (iii) any remedies
insofar as any party exercising such remedies may take any action which is
arbitrary or capricious, unreasonable, not in good faith, or not commercially
reasonable; (iv) provisions to the effect that failure to exercise or delay in
exercising rights or remedies will not operate as a waiver of any such right or
remedy or which purport to render ineffective any waiver, modification or
amendment not in writing; (v) waivers of any statutory or constitutional rights
or remedies; (vi) provisions to the effect that remedies are cumulative or that
stated remedies are not exclusive; and (vii) any provision for late payment
fees, default interest, liquidated damages or other fees, charges or amounts
that may be construed as a penalty.

(d)           We
