COMMON STOCK PURCHASE WARRANT

 To Purchase __________ Shares of Common Stock of

Cyberkinetics Neurotechnology Systems, Inc.

                     THIS
  COMMON STOCK PURCHASE 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 the close of business on the five year anniversary of the
  Initial Exercise Date (the "Termination Date") but not thereafter, to
  subscribe for and purchase from Cyberkinetics Neurotechnology Systems, Inc.,
  a Delaware corporation (the "Company"), up to ______ shares (the "Warrant
  Shares") of Common Stock, par value $0.001 per share, of the Company (the
  "Common Stock"). The purchase price of one share of Common Stock under
  this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).

                     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 November 4, 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

 1

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); provided, however, within
  5 Trading Days of the date said Notice of Exercise is delivered to the Company,
  the Holder shall have surrendered this Warrant to the Company and 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.

                    b)           
  Exercise Price. The exercise price of the Common Stock under this Warrant
  shall be $6.00, subject to adjustment hereunder (the "Exercise Price").

                    c)           
  Cashless Exercise. If at any time after one year from the date of issuance
  of this Warrant there is no effective Registration Statement registering the
  resale of the Warrant Shares by the Holder, 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 Closing Price 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. 

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

                    d)           
   Exercise Limitations; Holder's Restrictions. The Holder shall not
  have the right to exercise any portion of this Warrant, pursuant to Section
  2(c) or otherwise, to the extent that after giving effect to such issuance after
  exercise, the Holder (together with the Holder's affiliates), as set forth on
  the applicable Notice of Exercise, would beneficially own in excess of 4.99%
  of the number of shares of the Common Stock outstanding immediately after giving
  effect to such issuance. For purposes of the foregoing sentence, the number
  of shares of Common Stock beneficially owned by the Holder 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 the number of shares of Common Stock which would be
  issuable upon (A) exercise of the remaining, nonexercised portion of this Warrant
  beneficially owned by the Holder or any of its affiliates and (B) exercise or
  conversion of the unexercised or nonconverted portion of any other securities
  of the Company (including, without limitation, any other Shares or Warrants)
  subject to a limitation on conversion or exercise analogous to the limitation
  contained herein beneficially owned by

 2

the Holder or any of its affiliates.
  Except as set forth in the preceding sentence, for purposes of this Section
  2(d), beneficial ownership shall be calculated in accordance with Section 13(d)
  of the Exchange Act, it being acknowledged by Holder that the Company is not
  representing to Holder that such calculation is in compliance with Section 13(d)
  of the Exchange Act and Holder is solely responsible for any schedules required
  to be filed in accordance therewith. To the extent that the limitation contained
  in this Section 2(d) applies, the determination of whether this Warrant is exercisable
  (in relation to other securities owned by the Holder) and of which a portion
  of this Warrant is exercisable shall be in the sole discretion of such Holder,
  and the submission of a Notice of Exercise shall be deemed to be such Holder's
  determination of whether this Warrant is exercisable (in relation to other securities
  owned by such Holder) and of which portion of this Warrant is exercisable, in
  each case subject to such aggregate percentage limitation, and the Company shall
  have no obligation to verify or confirm the accuracy of such determination.
  For purposes of this Section 2(d), 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 (x) the Company's most recent SEC Report, as
  the case may be, (y) a more recent public announcement by the Company or (z)
  any other notice by the Company or the Company's Transfer Agent setting forth
  the number of shares of Common Stock outstanding. Upon the written or oral request
  of the Holder, the Company shall within two Trading Days confirm orally and
  in writing 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 or its affiliates since the date as of
  which such number of outstanding shares of Common Stock was reported. The provisions
  of this Section 2(d) may be waived by the Holder upon, at the election of the
  Holder, not less than 61 days' prior notice to the Company, and the provisions
  of this Section 2(d) shall continue to apply until such 61st day
  (or such later date, as determined by the Holder, as may be specified in such
  notice of waiver). 

                    e)           
  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 in respect of the issue thereof (other
  than taxes in respect of any transfer occurring contemporaneously with such
  issue). 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 

 3

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. 

                    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 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(e)(vii) 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 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(e)(iv) by the Warrant Share Delivery Date, then the Holder
  will have the right to rescind such exercise.

                    v.          
  Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Exercise.
  In addition to any other rights available to the Holder, if the Company fails
  to cause its transfer agent to transmit to the Holder a certificate or certificates
  representing the Warrant Shares pursuant to an exercise on or before the Warrant
  Share Delivery Date, and if after such date the Holder is required by its broker
  to purchase (in an open market transaction or otherwise) shares of Common Stock
  to deliver in satisfaction of a sale by the Holder of the Warrant Shares which
  the Holder anticipated receiving upon such exercise (a "Buy-In"), then
  the Company shall (1) pay in cash to the Holder the amount by which (x) the

4

Holder's total purchase price (including
  brokerage commissions, if any) for the shares of Common Stock so purchased exceeds
  (y) the amount obtained by multiplying (A) the number of Warrant Shares that
  the Company was required to deliver to the Holder in connection with the exercise
  at issue times (B) the price at which the sell order giving rise to such purchase
  obligation was executed, and (2) at the option of the Holder, either reinstate
  the portion of the Warrant and equivalent number of Warrant Shares for which
  such exercise was not honored or deliver to the Holder the number of shares
  of Common Stock that would have been issued had the Company timely complied
  with its exercise and delivery obligations hereunder. For example, if the Holder
  purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In
  with respect to an attempted exercise of shares of Common Stock with an aggregate
  sale price giving rise to such purchase obligation of $10,000, under clause
  (1) of the immediately preceding sentence the Company shall be required to pay
  the Holder $1,000. The Holder shall provide the Company written notice indicating
  the amounts payable to the Holder in respect of the Buy-In, together with applicable
  confirmations and other evidence reasonably requested by the Company. Nothing
  herein shall limit a Holder's right to pursue any other remedies available to
  it hereunder, at law or in equity including, without limitation, a decree of
  specific performance and/or injunctive relief with respect to the Company's
  failure to timely deliver certificates representing shares of Common Stock upon
  exercise of the Warrant as required pursuant to the terms hereof. 

                    vi.          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 pay a cash adjustment in respect of such final fraction in
  an amount equal to such fraction multiplied by the Exercise Price. 

                     vii.         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. 

5

                    viii.        Closing
  of Books. The Company will not close its stockholder 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 pursuant
  to this Warrant), (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 before such event and of which the denominator shall
  be the number of shares of Common Stock outstanding 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 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)           
  [INTENTIONALLY OMITTED]. 

                    c)           
  Pro Rata Distributions. If the Company, at any time prior to the Termination
  Date, shall distribute to all holders of Common Stock (and not to Holders of
  the Warrants) 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 Exercise Price
  shall be adjusted by multiplying the Exercise 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 per share 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 Holders 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)           
  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

6

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 conversion of this Warrant, the
  Holder shall have the right to receive, for each Warrant Share that would have
  been issuable upon such exercise absent such Fundamental Transaction, at the
  option of the Holder, (a) upon exercise of this Warrant, the number of 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 reorganization, reclassification, merger, consolidation
  or disposition of assets by a Holder of the number of shares of Common Stock
  for which this Warrant is exercisable immediately prior to such event or (b)
  if the Company is acquired in an all cash transaction, 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 exercise,
  the determination of the Exercise 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 Exercise 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 exercise of 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 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 Section 3(d) and insuring that this Warrant (or
  any such replacement security) will be similarly adjusted upon any subsequent
  transaction analogous to a Fundamental Transaction. 

                    e)           
  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. 

                    f)           
  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. The
  number of shares of Common Stock outstanding at any given time shall not includes
  shares of Common Stock owned or held by or for the account of the Company, and
  the description of any such shares of Common Stock shall be considered on issue
  or sale of Common Stock. 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. 

 7

                    g)           
  Voluntary Adjustdeemed appropriate by the Board of Directors of the Company.
  ment 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

                    h)           
  Notice to Holders.

                    i.          
  Adjustment to Exercise Price. Whenever the Exercise Price is adjusted
  pursuant to 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) 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 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. 

Section 4.            
  Transfer of Warrant. 

 8

                    a)           
   Transferability. Subject to compliance with any applicable securities
  laws and the conditions set forth in Sections 5(a) and 4(d) 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. 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. 

Section 5.            
  Miscellaneous. 

                     a)           
  Title to 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

 9

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 Exercise Price (or by means of a cashless exercise), the Warrant
  Shares 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. 

                    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 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. 

                    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 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 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

 10

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. 

                    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 Shares acquired
  upon the exercise of this Warrant, if not 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 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 stockholder
  of the Company, whether such liability is asserted by the Company or by creditors
  of the Company. 

 11

                    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. 

                    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 Shares. 

                    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
  prohibition or invalidity, without invalidating the remainder of such provisions
  or the remaining provisions of this Warrant.

                    o)           
  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.

 2

by the Holders) substantially the "Plan
  of Distribution" attached hereto as Annex A. Subject to the terms
  of this Agreement, the Company shall use its best efforts to cause the Registration
  Statement to be declared effective under the Securities Act as promptly as possible
  after the filing thereof, but in any event not later than the Effectiveness
  Date, and shall use its best efforts to keep the Registration Statement continuously
  effective under the Securities Act until the date when all Registrable Securities
  covered by the Registration Statement have been sold or may be sold without
  volume restrictions pursuant to Rule 144(k) as determined by the counsel to
  the Company pursuant to a written opinion letter to such effect, addressed and
  acceptable to the Company's transfer agent and the affected Holders (the "Effectiveness
  Period").

                    (b)           
  If: (i) a Registration Statement is not filed on or prior to the Filing Date
  (if the Company files a Registration Statement without affording the Holder
  the opportunity to review and comment on the same as required by Section 3(a),
  the Company shall not be deemed to have satisfied this clause (i)), or (ii)
  the Company fails to file with the Commission a request for acceleration in
  accordance with Rule 461 promulgated under the Securities Act, within five Trading
  Days of the date that the Company is notified (orally or in writing, whichever
  is earlier) by the Commission that a Registration Statement will not be "reviewed,"
  or is not subject to further review, or (iii) prior to the date when such Registration
  Statement is first declared effective by the Commission, the Company fails to
  file a pre-effective amendment and otherwise respond in writing to comments
  made by the Commission in respect of such Registration Statement within 20 calendar
  days after the receipt of comments by or notice from the Commission that such
  amendment is required in order for a Registration Statement to be declared effective,
  or (iv) a Registration Statement filed or required to be filed hereunder is
  not declared effective by the Commission on or before the Effectiveness Date,
  or (v) after a Registration Statement is first declared effective by the Commission,
  it ceases for any reason to remain continuously effective as to all Registrable
  Securities for which it is required to be effective, or the Holders are not
  permitted to utilize the Prospectus therein to resell such Registrable Securities,
  for in any such case 10 consecutive calendar days but no more than an aggregate
  of 15 calendar days during any 12 month period (which need not be consecutive
  Trading Days)(any such failure or breach being referred to as an "Event,"
  and for purposes of clause (i) or (iv) the date on which such Event occurs,
  or for purposes of clause (ii) the date on which such five Trading Day period
  is exceeded, or for purposes of clause (iii) the date which such 20 calendar
  day period is exceeded, or for purposes of clause (v) the date on which such
  10 or 15 calendar day period, as applicable, is exceeded being referred to as
  "Event Date"), then in addition to any other rights the Holders may have
  hereunder or under applicable law, then, on each such Event Date and on each
  monthly anniversary of each such Event Date (if the applicable Event shall not
  have been cured by such date) until the applicable Event is cured, the Company
  shall pay to each Holder an amount in cash, as partial liquidated damages and
  not as a penalty, equal to 1.5% of the aggregate purchase price paid by such
  Holder pursuant to the Purchase Agreement for any Registrable Securities then
  held by such Holder. If the Company fails to pay any partial liquidated damages
  pursuant to this Section in full within seven days after the date payable, the
  Company will pay interest thereon at a rate of 12% per annum (or such lesser
  maximum amount that is permitted to be paid by applicable law) to the Holder,
  accruing daily from the date such partial liquidated

 3

damages are due until such amounts,
  plus all such interest thereon, are paid in full. The partial liquidated damages
  pursuant to the terms hereof shall apply on a daily pro-rata basis for any portion
  of a month prior to the cure of an Event. Notwithstanding anything herein to
  the contrary, if an Event or the continuation of an Event is caused solely as
  a result of an act or omission by a Holder, the Company shall not be liable
  to pay liquidated damages to such Holder that otherwise would result on account
  of such Event or continuation of an Event. 

                     3.                
  Registration Procedures 

                                       In
  connection with the Company's registration obligations hereunder, the Company
  shall:

                    (a)           
  Not less than five Trading Days prior to the filing of the Registration Statement
  or any related Prospectus or any amendment or supplement thereto, the Company
  shall, (i) furnish to the Holders copies of any disclosure relating to the Holders,
  including but not limited to the entire Selling Stockholder and Plan of Distribution
  sections which sections shall be subject to the review of such Holders, and
  (ii) cause its officers and directors, counsel and independent certified public
  accountants to respond to such inquiries as shall be necessary, in the reasonable
  opinion of respective counsel to conduct a reasonable investigation within the
  meaning of the Securities Act. The Company shall not file the Registration Statement
  or any such Prospectus or any amendments or supplements thereto to which the
  Holders of a majority of the Registrable Securities shall reasonably object
  in good faith, provided that the Company is notified of such objection in writing
  no later than 2 Trading Days after the Holders have been so furnished copies
  of such documents. Prior to any filing relating to the Registration Statement,
  each Holder agrees to furnish to the Company a completed Questionnaire in the
  form attached to this Agreement as Annex B (a "Selling Shareholder
  Questionnaire") within five Trading Days of written request by the
  Company.

                    (b)           
  (i) Prepare and file with the Commission such amendments, including post-effective
  amendments, to the Registration Statement and the Prospectus used in connection
  therewith as may be necessary to keep the Registration Statement continuously
  effective as to the applicable Registrable Securities for the Effectiveness
  Period and prepare and file with the Commission such additional Registration
  Statements in order to register for resale under the Securities Act all of the
  Registrable Securities; (ii) cause the related Prospectus to be amended or supplemented
  by any required Prospectus supplement, and as so supplemented or amended to
  be filed pursuant to Rule 424; (iii) respond as promptly as reasonably possible
  to any comments received from the Commission with respect to the Registration
  Statement or any amendment thereto and, as promptly as reasonably possible,
  upon request, provide the Holders upon request true and complete copies of all
  correspondence from and to the Commission relating to the Registration Statement;
  and (iv) comply in all material respects with the provisions of the Securities
  Act and the Exchange Act with respect to the disposition of all Registrable
  Securities covered by the Registration Statement during the applicable period
  in accordance with the intended methods of disposition by the Holders thereof
  set forth in the Registration Statement as so amended or in such Prospectus
  as so supplemented. 

 4

                    (c)           
  Notify the Holders of Registrable Securities to be sold as promptly as reasonably
  possible and (if requested by any such Person) confirm such notice in writing
  promptly following the day (i)(A) when a Prospectus or any Prospectus supplement
  or post-effective amendment to the Registration Statement is proposed to be
  filed; (B) when the Commission notifies the Company whether there will be a
  "review" of the Registration Statement and whenever the Commission comments
  in writing on the Registration Statement (the Company shall upon request provide
  true and complete copies thereof and all written responses thereto to each of
  the Holders); and (C) with respect to the Registration Statement or any post-effective
  amendment, when the same has become effective; (ii) of any request by the Commission
  or any other Federal or state governmental authority during the period of effectiveness
  of the Registration Statement for amendments or supplements to the Registration
  Statement or Prospectus or for additional information; (iii) of the issuance
  by the Commission or any other federal or state governmental authority of any
  stop order suspending the effectiveness of the Registration Statement covering
  any or all of the Registrable Securities or the initiation of any Proceedings
  for that purpose; (iv) of the receipt by the Company of any notification with
  respect to the suspension of the qualification or exemption from qualification
  of any of the Registrable Securities for sale in any jurisdiction, or the initiation
  or threatening of any Proceeding for such purpose; and (v) of the occurrence
  of any event or passage of time that makes the financial statements included
  in the Registration Statement ineligible for inclusion therein or any statement
  made in the Registration Statement or Prospectus or any document incorporated
  or deemed to be incorporated therein by reference untrue in any material respect
  or that requires any revisions to the Registration Statement, Prospectus or
  other documents so that, in the case of the Registration Statement or the Prospectus,
  as the case may be, it will not contain any untrue statement of a material fact
  or omit to state any material fact required to be stated therein or necessary
  to make the statements therein, in light of the circumstances under which they
  were made, not misleading. 

                    (d)           
  Use commercially reasonable efforts to avoid the issuance of, or, if issued,
  obtain the withdrawal of (i) any order suspending the effectiveness of the Registration
  Statement, or (ii) any suspension of the qualification (or exemption from qualification)
  of any of the Registrable Securities for sale in any jurisdiction, at the earliest
  practicable moment. 

                    (e)           
  Furnish to each Holder, without charge and upon request, at least one conformed
  copy of the Registration Statement and each amendment thereto, including financial
  statements and schedules, all documents incorporated or deemed to be incorporated
  therein by reference to the extent requested by such Person, and all exhibits
  to the extent requested by such Person (including those previously furnished
  or incorporated by reference) promptly after the filing of such documents with
  the Commission. 

                    (f)           
  Promptly deliver to each Holder, without charge and upon request, as many copies
  of the Prospectus or Prospectuses (including each form of prospectus) and each
  amendment or supplement thereto as such Persons may reasonably request in connection
  with resales by the Holder of Registrable Securities. Subject to the terms of

 5

this Agreement, the Company hereby consents
  to the use of such Prospectus and each amendment or supplement thereto by each
  of the selling Holders in connection with the offering and sale of the Registrable
  Securities covered by such Prospectus and any amendment or supplement thereto,
  except after the giving on any notice pursuant to Section 3(c). 

                    (g)           
  Prior to any resale of Registrable Securities by a Holder, use its commercially
  reasonable efforts to register or qualify or cooperate with the selling Holders
  in connection with the registration or qualification (or exemption from the
  Registration or qualification) of such Registrable Securities for the resale
  by the Holder under the securities or Blue Sky laws of such jurisdictions within
  the United States as any Holder reasonably requests in writing, to keep the
  Registration or qualification (or exemption therefrom) effective during the
  Effectiveness Period and to do any and all other acts or things reasonably necessary
  to enable the disposition in such jurisdictions of the Registrable Securities
  covered by the Registration Statement; provided, that the Company shall
  not be required to qualify generally to do business in any jurisdiction where
  it is not then so qualified, subject the Company to any tax in any such jurisdiction
  where it is not then so subject or file a general consent to service of process
  in any such jurisdiction. 

                    (h)           
  If requested by the Holders, cooperate with the Holders to facilitate the timely
  preparation and delivery of certificates representing Registrable Securities
  to be delivered to a transferee pursuant to the Registration Statement, which
  certificates shall be free, to the extent permitted by the Purchase 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.

                    (i)           
  Upon the occurrence of any event contemplated by Section 3(c)(v), as promptly
  as reasonably possible, prepare a supplement or amendment, including a post-effective
  amendment, to the Registration Statement or a supplement to the related Prospectus
  or any document incorporated or deemed to be incorporated therein by reference,
  and file any other required document so that, as thereafter delivered, neither
  the Registration Statement nor such Prospectus will contain an untrue statement
  of a material fact or omit to state a material fact required to be stated therein
  or necessary to make the statements therein, in light of the circumstances under
  which they were made, not misleading. If the Company notifies the Holders in
  accordance with clauses (ii) through (v) of Section 3(c) above to suspend the
  use of any Prospectus until the requisite changes to such Prospectus have been
  made, then the Holders shall suspend use of such Prospectus. The Company will
  use its best efforts to ensure that the use of the Prospectus may be resumed
  as promptly as is practicable. The Company shall be entitled to exercise its
  right under this Section 3(i) to suspend the availability of a Registration
  Statement and Prospectus, subject to the payment of partial liquidated damages
  pursuant to Section 2(b), for a period not to exceed 60 days (which need not
  be consecutive days) in any 12 month period. 

                    (j)           
  Comply with all applicable rules and regulations of the Commission.

                    (k)           
  The Company may require each selling Holder to furnish to the Company a certified
  statement as to the number of shares of Common Stock beneficially owned by such
  Holder and, if required by the Commission, the person thereof that has voting
  and dispositive control over the Shares. During any periods that the Company
  is unable to meet its obligations hereunder with respect to the registration
  of the Registrable Securities solely because any Holder fails to furnish such
  information within three Trading Days of the Company's request, any liquidated
  damages that are accruing at such time as to such Holder only shall be tolled
  and any Event that may otherwise occur solely because of such delay shall be
  suspended as to such Holder only, until such information is delivered to the
  Company. 

                  4.                
  Registration Expenses. All fees and expenses incident to the performance
  of or compliance with this Agreement by the Company shall be borne by the Company
  whether or not any Registrable Securities are sold pursuant to the Registration
  Statement. The fees and expenses referred to in the foregoing sentence shall
  include, without limitation, (i) all registration and filing fees (including,
  without limitation, fees and expenses with respect to filings required to be
  made with the Trading Market on which the Common Stock is then listed for trading,
  (ii) printing expenses (including, without limitation, expenses of printing
  certificates for Registrable Securities and of printing prospectuses if the
  printing of prospectuses is reasonably requested by the holders of a majority
  of the Registrable Securities included in the Registration Statement), (iii)
  messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel
  for the Company, (v) Securities Act liability insurance, if the Company so desires
  such insurance, and (vi) fees and expenses of all other Persons retained by
  the Company in connection with the consummation of the transactions contemplated
  by this Agreement. In addition, the Company shall be responsible for all of
  its internal expenses incurred in connection with the consummation of the transactions
  contemplated by this Agreement (including, without limitation, all salaries
  and expenses of its officers and employees performing legal or accounting duties),
  the expense of any annual audit and the fees and expenses incurred in connection
  with the listing of the Registrable Securities on any securities exchange as
  required hereunder. In no event shall the Company be responsible for any broker
  or similar commissions or, except to the extent provided for in the Transaction
  Documents, any legal fees or other costs of the Holders. 

                 5.                
Indemnification

                    (a)           
  Indemnification by the Company. The Company shall, notwithstanding any
  termination of this Agreement, indemnify and hold harmless each Holder, the
  officers, directors, agents and employees of each of them, each Person who controls
  any such Holder (within the meaning of Section 15 of the Securities Act or Section
  20 of the Exchange Act) and the officers, directors, agents and employees of
  each such controlling Person, to the fullest extent permitted by applicable
  law, from and against any and all losses, claims, damages, liabilities, costs
  (including, without limitation, reasonable attorneys' fees) and expenses (collectively,
  "Losses"), as incurred, arising out of or relating to any untrue or alleged
  untrue statement of a material fact contained in the Registration Statement,
  any Prospectus or any form of prospectus or in any amendment or supplement thereto
  or in any preliminary prospectus, or arising out of or relating to any omission
  or alleged omission of a material fact required to be stated therein or necessary
  to make the statements therein (in the case of any Prospectus or form of prospectus
  or

 7

supplement thereto, in light of the
  circumstances under which they were made) not misleading, except to the extent,
  but only to the extent, that (i) such untrue statements or omissions are based
  solely upon information regarding such Holder furnished in writing to the Company
  by such Holder expressly for use therein, or to the extent that such information
  relates to such Holder or such Holder's proposed method of distribution of Registrable
  Securities and was reviewed and expressly approved in writing by such Holder
  expressly for use in the Registration Statement, such Prospectus or such form
  of Prospectus or in any amendment or supplement thereto (it being understood
  that the Holder has approved Annex A hereto for this purpose) or (ii) in the
  case of an occurrence of an event of the type specified in Section 3(c)(ii)-(v),
  the use by such Holder of an outdated or defective Prospectus after the Company
  has notified such Holder in writing that the Prospectus is outdated or defective
  and prior to the receipt by such Holder of the Advice contemplated in Section
  6(d). The Company shall notify the Holders promptly of the institution, threat
  or assertion of any Proceeding of which the Company is aware in connection with
  the transactions contemplated by this Agreement. 

                    (b)           
  Indemnification by Holders. Each Holder shall, severally and not jointly,
  indemnify and hold harmless the Company, its directors, officers, agents and
  employees, each Person who controls the Company (within the meaning of Section
  15 of the Securities Act and Section 20 of the Exchange Act), and the directors,
  officers, agents or employees of such controlling Persons, to the fullest extent
  permitted by applicable law, from and against all Losses, as incurred, to the
  extent arising out of or based solely upon: (x) such Holder's failure to comply
  with the prospectus delivery requirements of the Securities Act or (y) any untrue
  or alleged untrue statement of a material fact contained in any Registration
  Statement, any Prospectus, or any form of prospectus, or in any amendment or
  supplement thereto or in any preliminary prospectus, or arising out of or relating
  to any omission or alleged omission of a material fact required to be stated
  therein or necessary to make the statements therein not misleading (i) to the
  extent, but only to the extent, that such untrue statement or omission is contained
  in any information so furnished in writing by such Holder to the Company specifically
  for inclusion in the Registration Statement or such Prospectus or (ii) to the
  extent that (1) such untrue statements or omissions are based solely upon information
  regarding such Holder furnished in writing to the Company by such Holder expressly
  for use therein, or to the extent that such information relates to such Holder
  or such Holder's proposed method of distribution of Registrable Securities and
  was reviewed and expressly approved in writing by such Holder expressly for
  use in the Registration Statement (it being understood that the Holder has approved
  Annex A hereto for this purpose), such Prospectus or such form of Prospectus
  or in any amendment or supplement thereto or (2) in the case of an occurrence
  of an event of the type specified in Section 3(c)(ii)-(v), the use by such Holder
  of an outdated or defective Prospectus after the Company has notified such Holder
  in writing that the Prospectus is outdated or defective and prior to the receipt
  by such Holder of the Advice contemplated in Section 6(d). In no event shall
  the liability of any selling Holder hereunder be greater in amount than the
  dollar amount of the net proceeds received by such Holder upon the sale of the
  Registrable Securities giving rise to such indemnification obligation. 

 8

                    (c)           
  Conduct of Indemnification Proceedings. If any Proceeding shall be brought
  or asserted against any Person entitled to indemnity hereunder (an "Indemnified
  Party"), such Indemnified Party shall promptly notify the Person from whom
  indemnity is sought (the "Indemnifying Party") in writing, and the Indemnifying
  Party shall have the right to assume the defense thereof, including the employment
  of counsel reasonably satisfactory to the Indemnified Party and the payment
  of all fees and expenses incurred in connection with defense thereof; provided,
  that the failure of any Indemnified Party to give such notice shall not relieve
  the Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
  except (and only) to the extent that it shall be finally determined by a court
  of competent jurisdiction (which determination is not subject to appeal or further
  review) that such failure shall have prejudiced the Indemnifying Party. 

                    An
  Indemnified Party shall have the right to employ separate counsel in any such
  Proceeding and to participate in the defense thereof, but the fees and expenses
  of such counsel shall be at the expense of such Indemnified Party or Parties
  unless: (1) the Indemnifying Party has agreed in writing to pay such fees and
  expenses; (2) the Indemnifying Party shall have failed promptly to assume the
  defense of such Proceeding and to employ counsel reasonably satisfactory to
  such Indemnified Party in any such Proceeding; or (3) the named parties to any
  such Proceeding (including any impleaded parties) include both such Indemnified
  Party and the Indemnifying Party, and such Indemnified Party shall reasonably
  believe that a material conflict of interest is likely to exist if the same
  counsel were to represent such Indemnified Party and the Indemnifying Party
  (in which case, if such Indemnified Party notifies the Indemnifying Party in
  writing that it elects to employ separate counsel at the expense of the Indemnifying
  Party, the Indemnifying Party shall not have the right to assume the defense
  thereof and the reasonable fees and expenses of one separate counsel shall be
  at the expense of the Indemnifying Party). The Indemnifying Party shall not
  be liable for any settlement of any such Proceeding effected without its written
  consent, which consent shall not be unreasonably withheld. No Indemnifying Party
  shall, without the prior written consent of the Indemnified Party, effect any
  settlement of any pending Proceeding in respect of which any Indemnified Party
  is a party, unless such settlement includes an unconditional release of such
  Indemnified Party from all liability on claims that are the subject matter of
  such Proceeding. 

                    Subject
  to the terms of this Agreement, all reasonable fees and expenses of the Indemnified
  Party (including reasonable fees and expenses to the extent incurred in connection
  with investigating or preparing to defend such Proceeding in a manner not inconsistent
  with this Section) shall be paid to the Indemnified Party, as incurred, within
  ten Trading Days of written notice thereof to the Indemnifying Party; provided,
  that the Indemnified Party shall promptly reimburse the Indemnifying Party for
  that portion of such fees and expenses applicable to such actions for which
  such Indemnified Party is not entitled to indemnification hereunder, determined
  based upon the relative faults of the parties. 

                    (d)           
  Contribution. If a claim for indemnification under Section 5(a) or 5(b)
  is unavailable to an Indemnified Party (by reason of public policy or otherwise),
  then each Indemnifying Party, in lieu of indemnifying such Indemnified Party,
  shall contribute to

 9

the amount paid or payable by such Indemnified
  Party as a result of such Losses, in such proportion as is appropriate to reflect
  the relative fault of the Indemnifying Party and Indemnified Party in connection
  with the actions, statements or omissions that resulted in such Losses as well
  as any other relevant equitable considerations. The relative fault of such Indemnifying
  Party and Indemnified Party shall be determined by reference to, among other
  things, whether any action in question, including any untrue or alleged untrue
  statement of a material fact or omission or alleged omission of a material fact,
  has been taken or made by, or relates to information supplied by, such Indemnifying
  Party or Indemnified Party, and the parties' relative intent, knowledge, access
  to information and opportunity to correct or prevent such action, statement
  or omission. The amount paid or payable by a party as a result of any Losses
  shall be deemed to include, subject to the limitations set forth in this Agreement,
  any reasonable attorneys' or other reasonable fees or expenses incurred by such
  party in connection with any Proceeding to the extent such party would have
  been indemnified for such fees or expenses if the indemnification provided for
  in this Section was available to such party in accordance with its terms. 

                    The
  parties hereto agree that it would not be just and equitable if contribution
  pursuant to this Section 5(d) were determined by pro rata allocation or by any
  other method of allocation that does not take into account the equitable considerations
  referred to in the immediately preceding paragraph. Notwithstanding the provisions
  of this Section 5(d), no Holder shall be required to contribute, in the aggregate,
  any amount in excess of the amount by which the proceeds actually received by
  such Holder from the sale of the Registrable Securities subject to the Proceeding
  exceeds the amount of any damages that such Holder has otherwise been required
  to pay by reason of such untrue or alleged untrue statement or omission or alleged
  omission, except in the case of fraud by such Holder. 

                    The
  indemnity and contribution agreements contained in this Section are in addition
  to any liability that the Indemnifying Parties may have to the Indemnified Parties.

                  6.                
  Miscellaneous

                    (a)           
  Remedies. In the event of a breach by the Company or by a Holder, of
  any of their obligations under this Agreement, each Holder or the Company, as
  the case may be, in addition to being entitled to exercise all rights granted
  by law and under this Agreement, including recovery of damages, will be entitled
  to specific performance of its rights under this Agreement. The Company and
  each Holder agree that monetary damages would not provide adequate compensation
  for any losses incurred by reason of a breach by it of any of the provisions
  of this Agreement and hereby further agrees that, in the event of any action
  for specific performance in respect of such breach, it shall waive the defense
  that a remedy at law would be adequate. 

                    (b)           
  No Piggyback on Registrations. Except as set forth on Schedule 6(b)
  attached hereto, neither the Company nor any of its security holders (other
  than the Holders in such capacity pursuant hereto) may include securities of
  the Company in a Registration Statement other than the Registrable Securities.
  The Company shall not file

 10

any other registration statement until
  after the Effective Date (other than registration statements on Form S-8). 

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

                    (d)           
  Discontinued Disposition. Each Holder agrees by its acquisition of such
  Registrable Securities that, upon receipt of a notice from the Company of the
  occurrence of any event of the kind described in Section 3(c), 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 its best efforts
  to ensure that the use of the Prospectus may be resumed as promptly as it practicable.
  The Company agrees and acknowledges that any periods during which the Holder
  is required to discontinue the disposition of the Registrable Securities hereunder
  shall be subject to the provisions of Section 2(b). 

                    (e)           
  Piggy-Back Registrations. If at any time during the Effectiveness Period
  there is not an effective Registration Statement covering all of the Registrable
  Securities and the Company shall determine to prepare and file with the Commission
  a registration statement relating to an offering for its own account under the
  Securities Act of any of its equity securities, other than on Form S-4 or Form
  S-8 (each as promulgated under the Securities Act) or their then equivalents
  relating to equity securities to be issued solely in connection with any acquisition
  of any entity or business or equity securities issuable in connection with the
  stock option or other employee benefit plans, then the Company shall send to
  each Holder a written notice of such determination and, if within fifteen days
  after the date of such notice, any such Holder shall so request in writing,
  the Company shall include in such registration statement all or any part of
  such Registrable Securities such Holder requests to be registered, subject to
  customary underwriter cutbacks applicable to all holders of registration rights.

                    (f)           
  Amendments and Waivers. The provisions of this Agreement, including the
  provisions of this sentence, may not be amended, modified or supplemented, and
  waivers or consents to departures from the provisions hereof may not be given,
  unless the same shall be in writing and signed by the Company and Holders of
  at least 66% of the then outstanding Registrable Securities. 

                    (g)           
  Notices. Any and all notices or other communications or deliveries required
  or permitted to be provided hereunder shall be made in accordance with the provisions
  of the Purchase Agreement. 

                    (h)           
  Successors and Assigns. This Agreement shall inure to the benefit of
  and be binding upon the successors and permitted assigns of each of the parties
  and shall

 11

inure to the benefit of each Holder.
  Each Holder may assign their respective rights hereunder in the manner and to
  the Persons as permitted under the Purchase Agreement. 

                     (i)           
  Execution and Counterparts. This Agreement may be executed in any number
  of counterparts, each of which when so executed shall be deemed to be an original
  and, all of which taken together shall constitute one and the same Agreement.
  In the event that any signature is delivered by facsimile transmission, such
  signature shall create a valid binding obligation of the party executing (or
  on whose behalf such signature is executed) the same with the same force and
  effect as if such facsimile signature were the original thereof.

                    (j)           
  Governing Law. All questions concerning the construction, validity, enforcement
  and interpretation of this Agreement shall be determined with the provisions
  of the Purchase Agreement. 

                    (k)           
  Cumulative Remedies. The remedies provided herein are cumulative and
  not exclusive of any remedies provided by law. 

                    (l)           
  Severability. If any term, provision, covenant or restriction of this
  Agreement is held by a court of competent jurisdiction to be invalid, illegal,
  void or unenforceable, the remainder of the terms, provisions, covenants and
  restrictions set forth herein shall remain in full force and effect and shall
  in no way be affected, impaired or invalidated, and the parties hereto shall
  use their commercially reasonable efforts to find and employ an alternative
  means to achieve the same or substantially the same result as that contemplated
  by such term, provision, covenant or restriction. It is hereby stipulated and
  declared to be the intention of the parties that they would have executed the
  remaining terms, provisions, covenants and restrictions without including any
  of such that may be hereafter declared invalid, illegal, void or unenforceable.

                    (m)           
  Headings. The headings in this Agreement are for convenience of reference
  only and shall not limit or otherwise affect the meaning hereof. 

                     (n)           
  Independent Nature of Holders' Obligations and Rights. The obligations
  of each Holder hereunder are several and not joint with the obligations of any
  other Holder hereunder, and no Holder shall be responsible in any way for the
  performance of the obligations of any other Holder hereunder. Nothing contained
  herein or in any other agreement or document delivered at any closing, and no
  action taken by any Holder pursuant hereto or thereto, shall be deemed to constitute
  the Holders as a partnership, an association, a joint venture or any other kind
  of entity, or create a presumption that the Holders are in any way acting in
  concert with respect to such obligations or the transactions contemplated by
  this Agreement. Each Holder shall be entitled to protect and enforce its rights,
  including without limitation the rights arising out of this Agreement, and it
  shall not be necessary for any other Holder to be joined as an additional party
  in any proceeding for such purpose.

 ANNEX A

 Plan of Distribution

                     The
  Selling Stockholders (the "Selling Stockholders") of the common stock
  ("Common Stock") of Cyberkinetics Neurotechnology Systems, Inc., a Delaware
  corporation (the "Company") and any of their pledgees, assignees and
  successors-in-interest may, from time to time, sell any or all of their shares
  of Common Stock on any stock exchange, market or trading facility on which the
  shares are traded or in private transactions. These sales may be at fixed or
  negotiated prices. The Selling Stockholders may use any one or more of the following
  methods when selling shares: 

	 ordinary brokerage transactions and transactions in which the broker-dealer
    solicits purchasers;

  	 block trades in which the broker-dealer will attempt to sell the shares
    as agent but may position and resell a portion of the block as principal to
    facilitate the transaction;

  	 purchases by a broker-dealer as principal and resale by the broker-dealer
    for its account;

	
an exchange distribution in accordance with the rules of the applicable exchange;

	
privately negotiated transactions;

	
settlement of short sales entered into after the date of this prospectus;

  	 broker-dealers may agree with the Selling Stockholders to sell a specified
    number of such shares at a stipulated price per share;

	
a combination of any such methods of sale;

  	 through the writing or settlement of options or other hedging transactions,
    whether through an options exchange or otherwise; or

	
any other method permitted pursuant to applicable law.

                     The
  Selling Stockholders may also sell shares under Rule 144 under the Securities
  Act of 1933, as amended (the "Securities Act"), if available, rather
  than under this prospectus. 

                     Broker-dealers
  engaged by the Selling Stockholders may arrange for other brokers-dealers to
  participate in sales. Broker-dealers may receive commissions or discounts from
  the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser
  of shares, from the purchaser) in amounts to be negotiated. Each Selling Stockholder
  does not expect these commissions and discounts relating to its sales of shares
  to exceed what is customary in the types of transactions involved. 

 15

                     In
  connection with the sale of our common stock or interests therein, the Selling
  Stockholders may enter into hedging transactions with broker-dealers or other
  financial institutions, which may in turn engage in short sales of the common
  stock in the course of hedging the positions they assume. The Selling Stockholders
  may also sell shares of our common stock short and deliver these securities
  to close out their short positions, or loan or pledge the common stock to broker-dealers
  that in turn may sell these securities. The Selling Stockholders may also enter
  into option or other transactions with broker-dealers or other financial institutions
  or the creation of one or more derivative securities which require the delivery
  to such broker-dealer or other financial institution of shares offered by this
  prospectus, which shares such broker-dealer or other financial institution may
  resell pursuant to this prospectus (as supplemented or amended to reflect such
  transaction). 

                     The
  Selling Stockholders and any broker-dealers or agents that are involved in selling
  the shares may be deemed to be "underwriters" within the meaning of the Securities
  Act in connection with such sales. In such event, any commissions received by
  such broker-dealers or agents and any profit on the resale of the shares purchased
  by them may be deemed to be underwriting commissions or discounts under the
  Securities Act. Each Selling Stockholder has informed the Company that it does
  not have any agreement or understanding, directly or indirectly, with any person
  to distribute the Common Stock. 

                     The
  Company is required to pay certain fees and expenses incurred by the Company
  incident to the registration of the shares. The Company has agreed to indemnify
  the Selling Stockholders against certain losses, claims, damages and liabilities,
  including liabilities under the Securities Act.

                     Because
  Selling Stockholders may be deemed to be "underwriters" within the meaning of
  the Securities Act, they will be subject to the prospectus delivery requirements
  of the Securities Act. In addition, any securities covered by this prospectus
  which qualify for sale pursuant to Rule 144 under the Securities Act may be
  sold under Rule 144 rather than under this prospectus. Each Selling Stockholder
  has advised us that they have not entered into any agreements, understandings
  or arrangements with any underwriter or broker-dealer regarding the sale of
  the resale shares. There is no underwriter or coordinating broker acting in
  connection with the proposed sale of the resale shares by the Selling Stockholders.

                     We
  agreed to keep this prospectus effective until the earlier of (i) the date on
  which the shares may be resold by the Selling Stockholders without registration
  and without regard to any volume limitations by reason of Rule 144(k) under
  the Securities Act or any other rule of similar effect or (ii) all of the shares
  have been sold pursuant to the prospectus or Rule 144 under the Securities Act
  or any other rule of similar effect. The resale shares will be sold only through
  registered or licensed brokers or dealers if required under applicable state
  securities laws. In addition, in certain states, the resale shares may not be
  sold unless they have been registered or qualified for sale in the applicable
  state or an exemption from the registration or qualification requirement is
  available and is complied with. 

                     Under
  applicable rules and regulations under the Exchange Act, any person engaged
  in the distribution of the resale shares may not simultaneously engage in market
  making activities with respect to our common stock for a period of two business
  days prior to the commencement

16

 of the distribution. In addition, the Selling Stockholders
  will be subject to applicable provisions of the Exchange Act and the rules and
  regulations thereunder, including Regulation M, which may limit the timing of
  purchases and sales of shares of our common stock by the Selling Stockholders
  or any other person. We will make copies of this prospectus available to the
  Selling Stockholders and have informed them of the need to deliver a copy of
  this prospectus to each purchaser at or prior to the time of the sale.
