SERIES B CONVERTIBLE PREFERRED STOCK WARRANT

 

To Purchase              Shares of Series B Convertible Preferred Stock

 

Cambridge Heart, Inc.

 

THIS WARRANT (the “Warrant”) certifies that, for value received,
                     (the “Holder”), is entitled, upon the terms and subject to
the limitations on exercise and the conditions hereinafter set forth, at any
time on or after the date hereof (the “Initial Exercise Date”) and on or prior
to 5:00 p.m. (New York City time) on December 6, 2009 (the “Termination Date”)
but not thereafter, to subscribe for and purchase from Cambridge Heart, Inc., a
Delaware corporation (the “Company”), up to              shares of Preferred
Stock (the “Warrant Preferred Stock”) at a purchase price of $1,100 per share
(the “Warrant Exercise Price”) or Common Stock of the Company, in certain
circumstances as described herein. The initial conversion price of the Warrant
Preferred Stock shall be equal to $0.45, subject to adjustment hereunder
(“Warrant Conversion Price”). The Warrant Preferred Stock shall be in the form
of the Preferred Stock (with the same rights, privileges and preferences set
forth in the Transaction Documents, including without limitation, the
Certificate of Designation) issued pursuant to the Purchase Agreement, mutatis
mutandis.

 

Section 1. Definitions. Capitalized terms used and not otherwise defined herein
shall have the meanings set forth in that certain Securities Purchase Agreement
(the “Purchase Agreement”), dated as of December 6, 2004, among the Company and
the purchasers signatory thereto.

--------------------------------------------------------------------------------

Section 2. Exercise.

 

a) Exercise of Warrant. Exercise of the purchase rights represented by this
Warrant may be made 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 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 the payment of the Warrant Exercise Price therefor by wire
transfer or cashier’s check drawn on a United States bank. Upon exercise of the
Warrant, the Company shall issue shares of Warrant Preferred Stock with a per
share Stated Value (as defined in the Certificate of Designation) of $1000.

 

b) Cashless Exercise. If at any time after one (1) year from the date of
issuance of this Warrant there is no effective Registration Statement
registering the resale of the Warrant Shares underlying the Warrant Preferred
Stock issuable hereunder, then this Warrant may also be exercised at such time
for shares of Common Stock by means of a “cashless exercise” in which the Holder
shall be entitled to receive a certificate for the number of Common Stock equal
to the quotient obtained by dividing [(A-B) (X)] by (A), where:

 

(A) =

  the average VWAP for the five Trading Days immediately preceding the date of
such election;

(B)  =

  the Warrant Conversion Price, as adjusted; and

(X)  =

  the number of Warrant Shares issuable upon conversion of the Warrant Preferred
Stock issuable hereunder in accordance with the terms of this Warrant by means
of a cash exercise of this Warrant followed by an immediate conversion of such
Warrant Preferred Stock issuable thereupon rather than a cashless exercise.

 

Notwithstanding anything herein to the contrary, on the Termination Date, this
Warrant shall be automatically exercised via cashless exercise pursuant to this
Section 2(b).

 

c) Mechanics of Exercise.

 

i. Authorization of Warrant Preferred Stock. 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 all of the shares of Common Stock underlying the Warrant Preferred Stock (the
“Warrant Conversion Shares”). 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 certificates to execute and issue the necessary
certificates for the Warrant Preferred Stock upon the exercise of the purchase
rights under this Warrant and certificates upon conversion and exercise of the
Warrant

 

2

--------------------------------------------------------------------------------

Preferred Stock. The Company covenants that the Warrant Preferred Stock which
may be issued upon the exercise of the purchase rights represented by this
Warrant and the Warrant Conversion Shares issuable thereunder 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 in respect of the issue thereof (other than taxes in respect of any
transfer occurring contemporaneously with such issue). The Company will take all
such reasonable action as may be necessary to assure that the Warrant Preferred
Stock and Warrant Conversion 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.

 

ii. Delivery of Certificates Upon Exercise. Certificates for the Warrant
Preferred Stock purchased hereunder shall be delivered to the Holder within
three (3) Trading Days from the delivery to the Company of the Notice of
Exercise Form, surrender of this Warrant and payment of the Warrant Exercise
Price as set forth above (“Warrant Security Delivery Date”). This Warrant shall
be deemed to have been exercised on the date the payment of the principal amount
is received by the Company. The Warrant Preferred Stock 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 security for all
purposes, as of the date the Warrant has been exercised by payment to the
Company of the principal amount and all taxes required to be paid by the Holder,
if any, pursuant to Section 2(e)(vii) prior to the issuance of such security,
have been paid.

 

iii. Delivery of New Warrants Upon Exercise. If this Warrant shall have been
exercised in part, the Company shall, at the time of delivery of the certificate
or certificates representing the Warrant Preferred Stock, deliver to Holder a
new Warrant evidencing the rights of Holder to purchase the unpurchased Warrant
Preferred Stock 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 deliver to the Holder a
certificate or certificates representing the Warrant Preferred Stock pursuant to
this Section 2(e)(iv) by the Warrant Security Delivery Date, then the Holder
will have the right to rescind such exercise.

 

v. Charges, Taxes and Expenses. Issuance of certificates for Warrant Preferred
Stock 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;

 

3

--------------------------------------------------------------------------------

provided, however, that in the event certificates for Warrant Preferred Stock
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.

 

vi. Closing of Books. The Company will not close its records in any manner which
prevents the timely exercise of this Warrant, pursuant to the terms hereof or
the conversion of the Warrant Preferred Stock pursuant to the terms hereof.

 

d) Call Provision. Subject to the provisions of this Section 2(d), if after the
Effective Date the Closing Price for each of twenty (20) consecutive Trading
Days (the “Measurement Period”, which period shall not have commenced until
after the Effective Date) exceeds $1.35, subject to adjustment for reverse and
forward stock splits, stock dividends, stock combinations and other similar
transactions of the Common Stock (the “Threshold Price”), then the Company may,
within one Trading Day of the end of such period, call for cancellation of all
or any portion of this Warrant for which a Notice of Exercise has not yet been
delivered (such right, a “Call”). To exercise this right, the Company must
deliver to the Holder an irrevocable written notice (a “Call Notice”),
indicating therein the portion of unexercised portion of this Warrant to which
such notice applies. If the conditions set forth below for such Call are
satisfied from the period from the date of the Call Notice through and including
the Call Date (as defined below), then any portion of this Warrant subject to
such Call Notice for which a Notice of Exercise shall not have been received by
the Call Date will be cancelled at 6:30 p.m. (New York City time) on the 30th
Trading Day after the date the Call Notice is received by the Holder (such date,
the “Call Date”). Any unexercised portion of this Warrant to which the Call
Notice does not pertain will be unaffected by such Call Notice. In furtherance
thereof, the Company covenants and agrees that it will honor all Notices of
Exercise with respect to Warrant Preferred Stock subject to a Call Notice that
are tendered through 6:30 p.m. (New York City time) on the Call Date. The
parties agree that any Notice of Exercise delivered following a Call Notice
shall first reduce to zero the number of Warrant Preferred Stock subject to such
Call Notice prior to reducing the remaining Warrant Preferred Stock available
for purchase under this Warrant. For example, if (x) this Warrant then permits
the Holder to acquire $1,000 Stated Value of Warrant Preferred Stock, (y) a Call
Notice pertains to $750 Stated Value of Warrant Preferred Stock, and (z) prior
to 6:30 p.m. (New York City time) on the Call Date the Holder tenders a Notice
of Exercise in respect of $500 Stated Value of Warrant Preferred Stock, then (1)
on the Call Date the right under this Warrant to acquire $250 Stated Value of
Warrant Preferred Stock will be automatically cancelled, (2) the Company, in the
time and manner required under this Warrant, will have issued and delivered to
the Holder $500 Stated Value of Warrant Preferred Stock in respect of the
exercises following receipt of the Call Notice, and (3) the Holder may, until
the Termination Date, exercise this Warrant for $250 Stated Value of Warrant
Preferred Stock (subject to adjustment as herein provided and subject to
subsequent Call Notices). Subject again to the provisions of this Section 2(d),
the Company may deliver subsequent Call Notices for any portion of this Warrant
for which

 

4

--------------------------------------------------------------------------------

the Holder shall not have delivered a Notice of Exercise. Notwithstanding
anything to the contrary set forth in this Warrant, the Company may not deliver
a Call Notice or require the cancellation of this Warrant (and any Call Notice
will be void), unless, from the beginning of the 20th consecutive Trading Days
used to determine whether the Common Stock has achieved the Threshold Price
through the Call Date, (i) the Company shall have honored in accordance with the
terms of this Warrant and the Warrant Preferred Stock issuable hereunder all
Notices of Exercise delivered by 6:30 p.m. (New York City time) on the Call
Date, (ii) the Registration Statement shall be effective as to all Warrant
Conversion Shares and the prospectus thereunder available for use by the Holder
for the resale of all such Warrant Conversion Shares and (iii) the Common Stock
shall be listed or quoted for trading on the Trading Market. The Company’s right
to Call the Warrant shall be exercised ratably among the Holders based on each
Holder’s initial purchase of Common Stock pursuant to the Purchase Agreement.

 

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
pursuant to the Warrant Preferred Stock), (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 Warrant Conversion
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
before such event and of which the denominator shall be the number of shares of
Common Stock outstanding after such event. Any adjustment made pursuant to this
Section 3(a) shall become effective immediately after the record date for the
determination of stockholders 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) Subsequent Equity Sales. If the Company or any Subsidiary thereof, as
applicable, at any time while this Warrant is outstanding, shall offer, sell,
grant any option to purchase or offer, sell or grant any right to reprice its
securities, or otherwise dispose of or issue (or announce any offer, sale, grant
or any option to purchase or other disposition) any Common Stock or Common Stock
Equivalents entitling any Person to acquire shares of Common Stock, at an
effective price per share less than the then Warrant Conversion Price (such
lower price, the “Base Share Price” and such issuances collectively, a “Dilutive
Issuance”), as adjusted hereunder (if the holder of the Common Stock or Common
Stock Equivalents so issued shall at any time, whether by operation of purchase
price adjustments, reset provisions, floating conversion, exercise or exchange
prices or otherwise, or due to warrants, options or rights per share which is
issued in connection with such issuance, be entitled to receive shares of Common
Stock at an effective price per share which is less than the Warrant Conversion
Price, such issuance

 

5

--------------------------------------------------------------------------------

shall be deemed to have occurred for less than the Warrant Conversion Price),
then, the Warrant Conversion Price shall be reduced to a price equal to 110% of
the Base Share Price. Such adjustment shall be made whenever such Common Stock
or Common Stock Equivalents are issued. The Company shall notify the Holder in
writing, no later than the Trading Day following the issuance of any Common
Stock or Common Stock Equivalents subject to this section, indicating therein
the applicable issuance price, or of applicable reset price, exchange price,
conversion price and other pricing terms (such notice the “Dilutive Issuance
Notice”). For purposes of clarification, whether or not the Company provides a
Dilutive Issuance Notice pursuant to this Section 3(b), upon the occurrence of
any Dilutive Issuance, after the date of such Dilutive Issuance the Holder is
entitled to receive a number of securities based upon the Base Share Price
regardless of whether the Holder accurately refers to the Base Share Price in
the Notice of Exercise.

 

c) Pro Rata Distributions. If the Company, at any time while this Warrant is
outstanding, distributes to all holders of Common Stock (and not to Holders)
evidences of its indebtedness or assets or rights or warrants to subscribe for
or purchase any security other than the Common Stock (which shall be subject to
Section 3(b), then in each such case the Warrant Conversion Price shall be
determined by multiplying such Warrant Conversion Price in effect immediately
prior to the record date fixed for determination of stockholders entitled to
receive such distribution by a fraction of which the denominator shall be the
Closing Price determined as of the record date mentioned above, and of which the
numerator shall be such Closing Price on such record date less the then fair
market value at such record date of the portion of such assets or evidence of
indebtedness so distributed applicable to one outstanding share of the Common
Stock as determined by the Board of Directors in good faith. In either case the
adjustments shall be described in a statement provided to the Holder of the
portion of assets or evidences of indebtedness so distributed or such
subscription rights applicable to one share of Common Stock. Such adjustment
shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.

 

d) Calculations. All calculations and adjustments to the Warrant Conversion
Price 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 outstanding as of a given date shall be the sum
of the number of shares of Common Stock (excluding treasury shares, if any)
outstanding.

 

e) Notice to Holders.

 

i. Adjustment to Warrant Conversion Price. Whenever the Warrant Conversion Price
is adjusted pursuant to this Section 3, the Company shall promptly mail to each
Holder a notice setting forth the Warrant Conversion 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) on the Common Stock; (B) the Company shall
declare a special nonrecurring cash dividend on or a

 

6

--------------------------------------------------------------------------------

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 stockholders 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 addresses 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 the date
of such notice to the effective date of the event triggering such notice.

 

f) Fundamental Transaction. If, at any time while this Warrant is outstanding,
(A) the Company effects any merger or consolidation of the Company with or into
another Person, (B) the Company effects any sale of all or substantially all of
its assets in one or a series of related transactions, (C) any tender offer or
exchange offer (whether by the Company or another Person) is completed pursuant
to which holders of Common Stock are permitted to tender or exchange their
shares for other securities, cash or property, or (D) the Company effects any
reclassification of the Common Stock or any compulsory share exchange pursuant
to which the Common Stock is effectively converted into or exchanged for other
securities, cash or property (in any such case, a “Fundamental Transaction”),
then, upon any subsequent exercise of this Warrant the Holder shall have the
right to receive upon conversion of the Warrant Preferred Stock, as applicable,
for each Warrant Conversion Share that would have been issuable upon such
exercise and then subsequent conversion absent such Fundamental Transaction, at
the option of the Holder, (a) upon conversion of the Warrant Preferred Stock,
shares of Common Stock of the successor or acquiring corporation or of the
Company, if it is the surviving corporation, and Alternate Consideration
receivable upon or as a result of such

 

7

--------------------------------------------------------------------------------

reorganization, reclassification, merger, consolidation or disposition of assets
by a Holder of the number of shares of Common Stock for which the underlying
Warrant Preferred Stock are convertible immediately prior to such event or (b)
cash equal to the value of this Warrant as determined in accordance with the
Black-Scholes option pricing formula (the “Alternate Consideration”). For
purposes of any such deemed conversion, the determination of the Warrant
Conversion Price shall be appropriately adjusted to apply to such Alternate
Consideration based on the amount of Alternate Consideration issuable in respect
of one share of Common Stock in such Fundamental Transaction, and the Company
shall apportion the Warrant Conversion Price among the Alternate Consideration
in a reasonable manner reflecting the relative value of any different components
of the Alternate Consideration. If holders of Common Stock are given any choice
as to the securities, cash or property to be received in a Fundamental
Transaction, then the Holder shall be given the same choice as to the Alternate
Consideration it receives upon any conversion or exercise of the Warrant
Preferred Stock underlying this Warrant following such Fundamental Transaction.
To the extent necessary to effectuate the foregoing provisions, any successor to
the Company or surviving entity in such Fundamental Transaction shall issue to
the Holder a new Warrant consistent with the foregoing provisions and evidencing
the Holder’s right to exercise such Warrant ultimately into Alternate
Consideration. The terms of any agreement pursuant to which a Fundamental
Transaction is effected shall include terms requiring any such successor or
surviving entity to comply with the provisions of this paragraph (f) and
insuring that this Warrant (or any such replacement security) will be similarly
adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

 

g) Exempt Issuance. Notwithstanding the foregoing, no adjustments, Alternate
Consideration nor notices shall be made, paid or issued under this Section 3 in
respect of an Exempt Issuance.

 

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

 

Section 4. Transfer of Warrant.

 

a) Transferability. Subject to compliance with any applicable securities laws
and the conditions set forth in Sections 5(a) and 4(e) hereof and to the
provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights
hereunder are transferable, in whole or in part, upon surrender of this Warrant
at the principal office of the Company, 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. An Warrant, if properly assigned, may be
exercised by a new holder for the purchase of Warrant Preferred Stock without
having a new Warrant issued.

 

8

--------------------------------------------------------------------------------

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.

 

Section 5. Miscellaneous.

 

a) Title to the Warrant. Prior to the Termination Date and subject to compliance
with applicable laws and Section 4 of this Warrant, this Warrant and all rights
hereunder are transferable, in whole or in part, at the office or agency of the
Company by the Holder in person or by duly authorized attorney, upon surrender
of this Warrant together with the Assignment Form annexed hereto properly
endorsed. The transferee shall sign an investment letter in form and substance
reasonably satisfactory to the Company.

 

b) 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. Upon the surrender of this Warrant and the payment
of the aggregate principal, the Warrant Preferred Stock so purchased shall be
and be deemed to be issued to such Holder as the record owner of such shares as
of the close of business on the later of the date of such surrender or payment.

 

9

--------------------------------------------------------------------------------

c) 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 certificate
relating to the Warrant Preferred Stock, 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 certificate, if mutilated, the
Company will make and deliver a new Warrant or certificate of like tenor and
dated as of such cancellation, in lieu of such Warrant or certificate.

 

d) 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 be a Saturday, Sunday or a legal holiday, then such action may be taken or
such right may be exercised on the next succeeding day not a Saturday, Sunday or
legal holiday.

 

e) 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 shares of Common Stock issuable upon
conversion of the Warrant Preferred Stock. 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 certificates to execute and issue the
necessary certificates for the Warrant Preferred Stock 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 Preferred Stock and
Warrant Conversion 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 certificate
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 or the Warrant Preferred Stock, 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 and the Warrant Preferred Stock against
impairment. Without limiting the generality of the foregoing, the Company will
(a) 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
Preferred Stock upon the exercise of this Warrant and Warrant Conversion Shares
upon conversion of the Warrant Preferred Stock, and (b) use commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public

 

10

--------------------------------------------------------------------------------

regulatory body having jurisdiction thereof as may be necessary to enable the
Company to perform its obligations under this Warrant and the Warrant Preferred
Stock.

 

Before taking any action which would result in an adjustment in the Warrant
Preferred Stock for which this Warrant is exercisable or in the Warrant
Conversion 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.

 

f) 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.

 

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

 

h) 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 Holder’s rights, powers or remedies,
notwithstanding the fact that all rights hereunder terminate on the Termination
Date. If the Company willfully and knowingly fails to comply with any provision
of this Warrant, which results in any material damages to the Holder, the
Company shall pay to Holder 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 Holder in collecting any
amounts due pursuant hereto or in otherwise enforcing any of its rights, powers
or remedies hereunder.

 

i) 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.

 

j) Limitation of Liability. No provision hereof, in the absence of any
affirmative action by Holder to exercise this Warrant or purchase Warrant
Preferred Stock, 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 stockholder of the Company, whether such liability is
asserted by the Company or by creditors of the Company.

 

k) Remedies. Holder, in addition to being entitled to exercise all rights
granted by law, including recovery of damages, will be entitled to 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 the
defense in any action for specific performance that a remedy at law would be
adequate.

 

11

--------------------------------------------------------------------------------

l) 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 Preferred Stock.

 

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

 

n) 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
