THE ISSUANCE OF THIS WARRANT AND THE WARRANT SHARES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE BEEN REGISTERED BY THE COMPANY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A
REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED (REGISTRATION NO. 333-164336).




ATHERSYS, INC.



WARRANT TO PURCHASE COMMON STOCK



Warrant No.:_____________

Number of Shares of Common Stock:____________

Date of Issuance: February 2, 2011 (“Issuance Date”)




     Athersys, Inc., a Delaware corporation (the “Company”), hereby certifies that, for good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [INVESTOR
NAME], the registered holder hereof or its permitted assigns (the “Holder”), is entitled, subject
to the terms set forth below, to purchase from the Company, at the Exercise Price (as defined
below) then in effect, upon surrender of this Warrant to Purchase Common Stock (including any
Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, the
“Warrant”), at any time or times on or after the Issuance Date, but not after 5:00 p.m., New York
time, on the Expiration Date (as defined below), [_____ (_____)] (subject to adjustment as provided
herein) fully paid nonassessable shares of Common Stock (the “Warrant Shares”). Except as otherwise
defined herein, capitalized terms in this Warrant shall have the meanings set forth in Section
16. This Warrant is the Warrant issued pursuant to (i) Section 2 of that certain
Subscription Agreement dated as of January 27, 2011 (the “Subscription Date”), by and between the
Company and the Holder (the “Subscription Agreement” and together with the other subscription
agreements entered into by the Company on the Subscription Date, the “Subscription Agreements”) and
(ii) the Company’s Registration Statement on Form S-3 (Registration No. 333-164336) (the
“Registration Statement”).



     1. EXERCISE OF WARRANT.



          (a) Mechanics of Exercise. Subject to the terms and conditions hereof, this Warrant
may be exercised by the Holder on any day on or after the Issuance Date, in whole or in part, by
delivery of a written notice, in the form attached hereto as Exhibit A (the “Exercise
Notice”), of the Holder’s election to exercise this Warrant. Within two (2) days following the
Exercise Notice, the Holder shall make payment to the Company of an amount equal to the applicable
Exercise Price multiplied by the number of Warrant Shares as to which this Warrant is being
exercised (the “Aggregate Exercise Price”) in cash or by wire transfer of immediately available
funds, or provided the conditions for cashless exercise set forth in Section 1(e) are
satisfied, by notifying the Company that this Warrant is being exercised pursuant to a Cashless
Exercise (as defined in Section 1(e)). Execution and delivery of the Exercise Notice with
respect to less than all of the Warrant Shares shall have the same effect as cancellation of the
original Warrant and issuance of a new Warrant evidencing the right to purchase the remaining
number of Warrant Shares. On or before the first (1st) Business Day following the date on which
the Company has received the Exercise Notice, the Company shall transmit by facsimile an




 









 




acknowledgment of confirmation of receipt of the Exercise Notice to the Holder and the
Company’s transfer agent (the “Transfer Agent”). On or before the third (3rd) Business Day
following the date on which the Company has received the Exercise Notice (the “Share Delivery
Date”), the Company shall (X) provided that the Transfer Agent is participating in The Depository
Trust Company (“DTC”) Fast Automated Securities Transfer Program (the “FAST Program”), upon the
request of the Holder, credit such aggregate number of shares of Common Stock to which the Holder
is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC
through its Deposit Withdrawal Agent Commission system, or (Y) if the Transfer Agent is not
participating in the FAST Program, issue and dispatch by overnight courier to the address as
specified in the Exercise Notice, a certificate, registered in the Company’s share register in the
name of the Holder or its designee, for the number of shares of Common Stock to which the Holder is
entitled pursuant to such exercise. The Warrant Shares so purchased shall be deemed to be issued
to the Holder or the Holder’s designee, as the record owner of such Warrant Shares, as of the close
of business on the date of delivery of the Exercise Notice. If this Warrant is submitted in
connection with any exercise pursuant to this Section 1(a) and the number of Warrant Shares
represented by this Warrant submitted for exercise is greater than the number of Warrant Shares
being acquired upon an exercise, then the Company shall as soon as practicable and in no event
later than three (3) Business Days after any exercise and at its own expense, issue a new Warrant
(in accordance with Section 7(d)) representing the right to purchase the number of Warrant
Shares purchasable immediately prior to such exercise under this Warrant, less the number of
Warrant Shares with respect to which this Warrant is exercised. No fractional Common Stock are to
be issued upon the exercise of this Warrant, but rather the number of shares of Common Stock to be
issued shall be rounded up to the nearest whole number. The Company shall pay any and all transfer
taxes and transfer agent fees which may be payable with respect to the issuance and delivery of
Warrant Shares to the Holder upon exercise of this Warrant.




          (b)
Exercise Price. For purposes of this Warrant,
“Exercise Price” means $3.55, subject
to adjustment as provided herein.




          (c) Disputes. In the case of a dispute as to the determination of the Exercise Price
or the arithmetic calculation of the Warrant Shares, the Company shall promptly issue to the Holder
the number of Warrant Shares that are not disputed.




          (d) Limitations On Exercise. The Company shall not effect the exercise of this
Warrant, and the Holder shall not have the right to exercise this Warrant, to the extent that after
giving effect to such exercise, such Person (together with such Person’s affiliates) would
beneficially own in excess of 4.99% (the “Maximum Percentage”) of the Common Stock outstanding
immediately after giving effect to such exercise. For purposes of the foregoing sentence, the
aggregate number of shares of Common Stock beneficially owned by such Person and its affiliates
shall include the number of shares of Common Stock issuable upon exercise of this Warrant with
respect to which the determination of such sentence is being made, but shall exclude shares of
Common Stock which would be issuable upon (i) exercise of the remaining, unexercised portion of
this Warrant beneficially owned by such Person and its affiliates and (ii) exercise or conversion
of the unexercised or unconverted portion of any other securities of the Company beneficially owned
by such Person and its affiliates (including, without limitation, any convertible notes or
convertible shares or warrants) subject to a limitation on conversion or




2









 




exercise analogous to the limitation contained herein. Except as set forth in the preceding
sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance
with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, the
Holder may rely on the number of outstanding shares of Common Stock as reflected in the most recent
of (1) the Company’s most recent Form 10-K, Form 10-Q or other public filing with the Securities
and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company
or (3) any other notice by the Company or the Transfer Agent setting forth the number of shares of
Common Stock outstanding. For any reason at any time, upon the written or oral request of the
Holder, the Company shall within two (2) Business Days confirm to the Holder the number of shares
of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock
shall be determined after giving effect to the conversion or exercise of securities of the Company,
including this Warrant, by the Holder and its affiliates since the date as of which such number of
outstanding Common Stock was reported. By written notice to the Company, the Holder may from time
to time increase or decrease the Maximum Percentage to any other percentage not less than 4.99% and
not in excess of 9.99% specified in such notice; provided that (i) any such increase will not be
effective until the sixty-first (61st) day after such notice is delivered to the
Company and (ii) any such increase or decrease will apply only to the Holder. The provisions of
this paragraph shall be construed, corrected and implemented in a manner so as to effectuate the
intended beneficial ownership limitation herein contained. The limitations contained in this
paragraph shall apply to any successor Holder of this Warrant.




          (e) Limited Cashless Exercise. Notwithstanding anything contained herein to the
contrary, if a registration statement covering the Warrant Shares that are the subject of the
Exercise Notice (the “Unavailable Warrant Shares”) is not effective (other than if the Company
suspends the use of such registration statement for up to 60 days in any 12-month period if the
Company believes that the suspension is necessary because of some material non-public information
in the Company’s possession) or an exemption from registration is not available for the resale of
such Unavailable Warrant Shares, the Holder may, in its sole discretion, exercise this Warrant in
whole or in part and, in lieu of making the cash payment otherwise contemplated to be made to the
Company upon such exercise in payment of the Aggregate Exercise Price, elect instead to receive
upon such exercise the “Net Number” of shares of Common Stock determined according to the following
formula (a “Cashless Exercise”):




     Net Number = Y [(A-B)/A]



     where:



Y = the number of Warrant Shares with respect to which this Warrant is being exercised.

A = the VWAP for the five (5) Trading Days immediately prior to (but not including) the date of delivery of the Exercise Notice.

B = the Exercise Price.




          Upon receipt of an Exercise Notice to which this Section 1(e) is applicable, the
Company shall notify the Holder within one (1) Trading Day of such applicability and the
calculation of the Net Number of shares of Common Stock issuable upon the noticed exercise of




3









 




the Warrant utilizing Cashless Exercise, and confirm the Holder’s desire to complete the
exercise of the Warrant pursuant to this Section 1(e).




          For purposes of Rule 144 promulgated under the Securities Act of 1933, as amended, it is
intended, understood and acknowledged that the Warrant Shares issued in a cashless exercise
transaction shall be deemed to have been acquired by the Holder, and the holding period for the
Warrant Shares shall be deemed to have commenced, on the date this Warrant was originally issued.




          (f) Company’s Failure to Timely Deliver Securities. If the Company shall fail for any
reason or for no reason to issue to the Holder within the later of (i) three (3) Trading Days after
receipt of the applicable Exercise Notice and (ii) two (2) Trading Days after the Company’s receipt
of the Aggregate Exercise Price (or valid notice of a Cashless Exercise) (such later date, the
"Share Delivery Deadline”), a certificate for the number of Warrant Shares to which the Holder is
entitled and register such shares of Common Stock on the Company’s share register or to credit the
Holder’s balance account with DTC for such number of shares of Common Stock to which the Holder is
entitled upon the Holder’s exercise of this Warrant, and if on or after such Share Delivery
Deadline the Holder, or any third party on behalf of the Holder or for the Holder’s account,
purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in
satisfaction of a sale by the Holder of shares of Common Stock issuable upon such exercise that the
Holder anticipated receiving from the Company, then, so long as the Holder has paid the Aggregate
Exercise Price, the Company shall, within three (3) Business Days after the Holder’s request and in
the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total
purchase price (including brokerage commissions, if any) for the shares of Common Stock so
purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate
or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which
the Holder is entitled upon the Holder’s exercise hereunder, as the case may be (and to issue such
shares of Common Stock), shall terminate, or (ii) promptly honor its obligation to deliver to the
Holder a certificate or certificates representing such shares of Common Stock or credit the
Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is
entitled upon the Holder’s exercise hereunder, as the case may be, and pay cash to the Holder in an
amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of
shares of Common Stock, times (B) the Closing Sale Price on the Share Delivery Deadline.




     2. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES.



          The Exercise Price and the number of Warrant Shares shall be adjusted from time to time as
follows:




          (a) Adjustment upon Subdivision or Combination of Common Stock. If the Company at any
time on or after the Subscription Date subdivides (by any stock split, stock dividend,
recapitalization or otherwise) one or more classes of its outstanding Common Stock into a greater
number of shares, the Exercise Price in effect immediately prior to such subdivision will be
proportionately reduced and the number of Warrant Shares will be proportionately increased. If the
Company at any time on or after the Subscription Date combines (by any reverse




4









 




stock split, recapitalization or otherwise) one or more classes of its outstanding Common
Stock into a smaller number of shares, the Exercise Price in effect immediately prior to such
combination will be proportionately increased and the number of Warrant Shares will be
proportionately decreased. Any adjustment under this Section 2(a) shall become effective at
the close of business on the date the subdivision or combination becomes effective.




          (b) Other Events. If any event occurs of the type contemplated by the provisions of
this Section 2 but not expressly provided for by such provisions (including, without
limitation, the granting of stock appreciation rights or phantom stock rights to all stockholders),
then the Company’s Board of Directors will make an appropriate adjustment in the Exercise Price and
the number of Warrant Shares so as to protect the rights of the Holder; provided that no such
adjustment pursuant to this Section 2(b) will increase the Exercise Price or decrease the
number of Warrant Shares as otherwise determined pursuant to this Section 2.




          (c) Calculations. All calculations made under this Section 2 shall be made by
rounding to the nearest cent or the nearest 1/100th of a Common Share, as applicable.




     3. RIGHTS UPON DISTRIBUTION OF ASSETS.



          (a) If at any time or from time to time the holders of shares of Common Stock of the Company
(or any other securities at the time receivable upon the exercise of this Warrant) shall have
received or become entitled to receive, without payment therefor:




               (i) shares of Common Stock or other securities which are at any time directly or indirectly
convertible into or exchangeable for Common Stock, by way of dividend or other distribution (other
than an issuance due to a subdivision covered in Section 2(a) above);



               (ii) any cash paid or payable, including any declared and paid cash dividends; or



               (iii) shares of Common Stock or additional shares or other securities or property (including
cash) by way of spinoff, split-up, reclassification, combination of shares or similar corporate
rearrangement (other than shares of Common Stock pursuant to Section 2(a) above),


then and in each such case, the Holder hereof will, upon the exercise of this Warrant, be entitled
to receive, in addition to the number of shares of Common Stock receivable thereupon, and without
payment of any additional consideration therefor, the amount of shares of Common Stock and other
securities and property (including cash in the cases referred to in clause (iii) above) which such
Holder would hold on the date of such exercise had such Holder been the holder of record of such
Common Stock as of the date on which holders of Common Stock received or became entitled to receive
such shares or other securities and property, provided, however, (x) in the event that the holders
of Common Stock have received options, warrants or rights that have expired prior to the date of
exercise of this Warrant, the Holder shall not be entitled to receive such options, warrants or
rights and (y) in the event of a distribution consisting of cash as referred to in clause (ii)
above, the Exercise Price in effect immediately prior to such distribution will be proportionately
reduced by the amount of the distribution per Common Share such Holder would have been entitled to
receive had such Holder been the holder of record of






5









 







such Common Stock as of the date on which holders of Common Stock received or became entitled to
receive such cash distribution.




          (b) Upon the occurrence of each adjustment pursuant to this Section 3, the Company at
its expense will, at the written request of the Holder, promptly compute such adjustment in
accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment,
including a statement of the adjusted number or type of Warrant Shares or other securities issuable
upon exercise of this Warrant (as applicable), describing the transactions giving rise to such
adjustments and showing in detail the facts upon which such adjustment is based, including the
expiration date of any applicable options, warrants or rights. Upon written request, the Company
will promptly deliver a copy of each such certificate to the Holder and to the Transfer Agent. All
calculations made under this Section 3(b) shall be made by rounding to the nearest cent or
the nearest 1/100th of any security, as applicable.




     4. FUNDAMENTAL TRANSACTIONS.



          (a)
Fundamental Transactions. The Company shall not consummate a Fundamental Transaction (other than an Involuntary Change
of Control) or permit the consummation of any Involuntary Change of Control unless the Successor
Entity (if a Person other than the Company) assumes in writing all of the obligations of the
Company under this Warrant in accordance with the provisions of this
Section 4(a), including
agreements to deliver to each holder of Warrants in exchange for such Warrants a security of the
Successor Entity evidenced by a written instrument substantially similar in form and substance to
this Warrant, including, without limitation, an adjusted exercise price equal to the value for the
Common Stock reflected by the terms of such Fundamental Transaction, and exercisable for a
corresponding number of shares of capital stock equivalent to the Common Stock acquirable and
receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this
Warrant) prior to such Fundamental Transaction, and reasonably satisfactory to the Required Holders
(each such Fundamental Transaction, an “Assumption Fundamental Transaction”). Upon the occurrence
of any Assumption Fundamental Transaction, the Successor Entity shall succeed to, and be
substituted for (so that from and after the date of such Assumption Fundamental Transaction, the
provisions of this Warrant referring to the “Company” shall refer instead to the Successor Entity),
and may exercise every right and power of the Company and shall assume all of the obligations of
the Company under this Warrant with the same effect as if such Successor Entity (including its
Parent Entity) had been named as the Company herein. Notwithstanding the foregoing, the Holder may
elect, at its sole option, by delivery of written notice to the Company to waive this Section
4(a) to permit the Fundamental Transaction without the assumption of this Warrant. In addition to
and not in substitution for any other rights hereunder, prior to the consummation of any
Fundamental Transaction pursuant to which holders of Common Stock are entitled to receive
securities or other assets with respect to or in exchange for Common Stock (a “Corporate Event”),
the Company shall (or, with respect to any tender offer Involuntary Change of Control, shall use
its reasonable best efforts to) make appropriate provision to insure that the Holder will
thereafter have the right to receive upon an exercise of this Warrant at any time after the
consummation of the Fundamental Transaction but prior to the Expiration Date, in lieu of the Common
Stock (or other securities, cash, assets or other property) purchasable upon the exercise of the
Warrant prior to such Fundamental Transaction or the capital stock of the Successor Entity upon an
Assumption Fundamental Transaction, such shares, securities, cash, assets or any other property
whatsoever
(including warrants or other purchase or subscription rights) which the Holder would have been
entitled to receive upon the happening of such Fundamental Transaction had the Warrant been
exercised immediately prior to such Fundamental Transaction. 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 consideration it receives upon any exercise of
this Warrant following such Fundamental Transaction. The provisions of this Section shall apply
similarly and equally to successive Fundamental Transactions and Corporate Events and shall be
applied without regard to any limitations on the exercise of this Warrant.




          (b) Notwithstanding the foregoing, in the event of a Fundamental Transaction that is
(i) an all cash transaction or (ii) a Fundamental Transaction involving a person or entity whose
securities are not traded on a national securities exchange, including, but not limited to, the
NYSE Amex, the Nasdaq Global Select Market, the Nasdaq Global Market, or the Nasdaq Capital Market,
at the request of the Holder delivered before the 90th day after such Fundamental Transaction, the
Company (or the Successor Entity) shall purchase this Warrant from the Holder by paying to the
Holder, within five Business Days after such request (or, if later, on the effective date of the
Fundamental Transaction), cash in an amount equal to the Black Scholes Value of the remaining
unexercised portion of this Warrant on the date of such Fundamental Transaction.

     5. NONCIRCUMVENTION.



          The Company hereby covenants and agrees that the Company will not, by amendment of its
Certificate of Incorporation or through any reorganization, transfer of assets, consolidation,
merger, scheme of arrangement, 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,
and will at all times in good faith comply with all the provisions of this Warrant and take all
actions consistent with effectuating the purposes of this Warrant. Without limiting the generality
of the foregoing, the Company (i) shall not increase the par value of any Common Stock receivable
upon the exercise of this Warrant above the Exercise Price then in effect, (ii) shall take all such
actions as may be reasonably necessary or appropriate in order that the Company may validly and
legally issue fully paid and nonassessable Common Stock upon the exercise of this Warrant, and
(iii) shall, so long as this Warrant is outstanding, take all action reasonably necessary to
reserve and keep available out of its authorized and unissued Common Stock, solely for the purpose
of effecting the exercise of this Warrant, 100% of the number of shares of Common Stock issuable
upon exercise of this Warrant then outstanding (without regard to any limitations on exercise).




     6. WARRANT HOLDER NOT DEEMED A STOCKHOLDER.



          Except as otherwise specifically provided herein, the Holder, solely in such Person’s capacity
as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the
holder of share capital of the Company for any purpose, nor shall anything contained in this
Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of
this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or
withhold consent to any corporate action (whether any reorganization, issue of shares,
reclassification of shares, consolidation, merger, conveyance or otherwise), receive notice of
meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the
Holder of the Warrant Shares which such Person is then entitled to receive upon the due exercise of
this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any
liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise)
or as a stockholder of the Company, whether such liabilities are asserted by the Company or by
creditors of the Company.




7









 





     7. REISSUANCE OF WARRANTS; NO FRACTIONAL SHARES.



          (a) Transfer of Warrant. If this Warrant is to be transferred, the Holder shall
surrender this Warrant to the Company and deliver the completed and executed Assignment Form, in
the form attached hereto as Exhibit B, whereupon the Company will forthwith issue and
deliver upon the order of the Holder a new Warrant (in accordance with Section 7(d)),
registered as the Holder may request, representing the right to purchase the number of Warrant
Shares being transferred by the Holder and, if less than the total number of Warrant Shares then
underlying this Warrant is being transferred, a new Warrant (in accordance with Section
7(d)) to the Holder representing the right to purchase the number of Warrant Shares not being
transferred.




          (b) Lost, Stolen or Mutilated Warrant. Upon receipt by the Company of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this
Warrant, and, in the case of loss, theft or destruction, of any indemnification undertaking by the
Holder to the Company in customary form and, in the case of mutilation, upon surrender and
cancellation of this Warrant, the Company shall execute and deliver to the Holder a new Warrant (in
accordance with Section 7(d)) representing the right to purchase the Warrant Shares then
underlying this Warrant.




          (c) Exchangeable for Multiple Warrants. This Warrant is exchangeable, upon the
surrender hereof by the Holder at the principal office of the Company, for a new Warrant or
Warrants (in accordance with Section 7(d)) representing in the aggregate the right to
purchase the number of Warrant Shares then underlying this Warrant, and each such new Warrant will
represent the right to purchase such portion of such Warrant Shares as is designated by the Holder
at the time of such surrender; provided, however, that no Warrants for fractional Common Stock
shall be given.




          (d) Issuance of New Warrants. Whenever the Company is required to issue a new Warrant
pursuant to the terms of this Warrant, such new Warrant (i) shall be of like tenor with this
Warrant, (ii) shall represent, as indicated on the face of such new Warrant, the right to purchase
the Warrant Shares then underlying this Warrant (or in the case of a new Warrant being issued
pursuant to Section 7(a) or Section 7(c), the Warrant Shares designated by the
Holder which, when added to the number of shares of Common Stock underlying the other new Warrants
issued in connection with such issuance, does not exceed the number of Warrant Shares then
underlying this Warrant), (iii) shall have an issuance date, as indicated on the face of such new
Warrant which is the same as the Issuance Date, and (iv) shall have the same rights and conditions
as this Warrant.




     8. NOTICES.



          All notices required or permitted hereunder shall be in writing and shall be deemed
effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by
confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on
the next Business Day, (c) three (3) days after having been sent by registered or certified mail,
return receipt requested, postage prepaid, or (d) one (1) Business Day after deposit with a
nationally recognized overnight courier, with written verification of receipt. All communications
shall be sent to the Company at the address listed on the signature page hereto and to Holder at




8









 




the applicable address set forth on the applicable signature page to the Subscription
Agreement or at such other address as the Company or Holder may designate by ten (10) days advance
written notice to the other parties hereto.




     9. AMENDMENT AND WAIVER.



          Except as otherwise provided herein, the provisions of this Warrant may be amended and the
Company may take any action herein prohibited, or omit to perform any act herein required to be
performed by it, only if the Company has obtained the written consent of Holders owning a majority
in interest of the outstanding Warrants issued under the Subscription Agreements; provided, that
(x) any such amendment or waiver must apply to all Warrants issued by the Company pursuant to the
Subscription Agreements; and (y) the number of Warrant Shares subject to this Warrant, the Exercise
Price and the Expiration Date may not be amended, and the right to exercise this Warrant may not be
altered or waived, without the written consent of the Holder. No waiver of any provision hereunder
shall be effective unless it is in writing and signed by an authorized representative of the
waiving party.




     10. SEVERABILITY.



          If any provision of this Warrant is prohibited by law or otherwise determined to be invalid or
unenforceable by a court of competent jurisdiction, the provision that would otherwise be
prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that
it would be valid and enforceable, and the invalidity or unenforceability of such provision shall
not affect the validity of the remaining provisions of this Warrant so long as this Warrant as so
modified continues to express, without material change, the original intentions of the parties as
to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the
provision(s) in question does not substantially impair the respective expectations or reciprocal
obligations of the parties or the practical realization of the benefits that would otherwise be
conferred upon the parties. The parties will endeavor in good faith negotiations to replace the
prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which
comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).




     11. GOVERNING LAW.



          This Warrant shall be governed by and construed and enforced in accordance with, and all
questions concerning the construction, validity, interpretation and performance of this Warrant
shall be governed by, the internal laws of the State of New York, without giving effect to any
choice of law or conflict of law provision or rule (whether of the State of New York or any other
jurisdictions) that would cause the application of the laws of any jurisdictions other than the
State of New York.




     12. CONSTRUCTION; HEADINGS.



          This Warrant shall be deemed to be jointly drafted by the Company and the Holder and shall not
be construed against any person as the drafter hereof. The headings of this Warrant are for
convenience of reference and shall not form part of, or affect the interpretation of, this Warrant.

     13. DISPUTE RESOLUTION.



          In the case of a dispute as to the determination of the Exercise Price or the arithmetic
calculation of the Warrant Shares, the Company shall submit the disputed determinations or
arithmetic calculations via facsimile within two (2) Business Days of receipt of the Exercise
Notice giving rise to such dispute, as the case may be, to the Holder. If the Holder and the
Company are unable to agree upon such determination or calculation of the Exercise Price or the
Warrant Shares within three (3) Business Days of such disputed determination or arithmetic
calculation being submitted to the Holder, then the Company shall, within four (4) Business Days
submit via facsimile (a) the disputed determination of the Exercise Price to an independent,
reputable investment bank selected by the Company and approved by the Holder or (b) the disputed
arithmetic calculation of the Warrant Shares to the Company’s independent, outside accountant. The
Company shall cause at its expense the investment bank or the accountant, as the case may be, to
perform the determinations or calculations and notify the Company and the Holder of the results no
later than ten Business Days from the time it receives the disputed determinations or calculations.
Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be
binding upon all parties absent demonstrable error.




     14. REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF.



          The remedies provided in this Warrant shall be cumulative and in addition to all other
remedies available under this Warrant, at law or in equity (including a decree of specific
performance and/or other injunctive relief), and nothing herein shall limit the right of the Holder
to pursue actual damages for any failure by the Company to comply with the terms of this Warrant.




     15. TRANSFER.



          This Warrant may be offered for sale, sold, transferred, hypothecated or assigned without the
consent of the Company. This Warrant and the Warrant Shares have been registered by the Company
with the U.S. Securities and Exchange Commission pursuant to the Registration Statement.




     16. CERTAIN DEFINITIONS.



          For purposes of this Warrant, the following terms shall have the following meanings:




          (a) “Black Scholes Value” means the value of this Warrant based on the Black Scholes
Option Pricing Model obtained from the “OV” function on Bloomberg determined as of the day
of consummation of the applicable Fundamental Transaction for pricing purposes and
