aforedescribed purchase price per share, as adjusted from time to time as herein
provided, is referred to herein as the “Purchase Price."  The number
and character of such shares of Common Stock and the Purchase Price are subject
to adjustment as provided herein.  The Company may reduce the Purchase
Price for some or all of the Warrants, temporarily or permanently, provided such
reduction is made as to all outstanding Warrants for all Holders of such
Warrants.  Capitalized terms used and not otherwise defined herein
shall have the meanings set forth in that certain Subscription Agreement (the
“Subscription
Agreement”), dated as of November ___, 2009, entered into by the Company
and the Holder.

    


    As used
herein the following terms, unless the context otherwise requires, have the
following respective meanings:

     

    (a)           The
term “Company” shall
mean Advanced Cell Technology, Inc., a Delaware corporation, and any corporation
which shall succeed or assume the obligations of Advanced Cell Technology, Inc.
hereunder.

     

    (b)           The
term “Common Stock”
includes (i) the Company's Common Stock, $0.001 par value per share, as
authorized on the date of the Subscription Agreement, and (ii) any other
securities into which or for which any of the securities described in
(i) may be converted or exchanged pursuant to a plan of recapitalization,
reorganization, merger, sale of assets or otherwise.

     

    
      
        
        

      

      
        1

        
          

        

      

      
        
        

      

    

     

    (c)           The
term “Other Securities”
refers to any stock (other than Common Stock) and other securities of the
Company or any other person (corporate or otherwise) which the holder of the
Warrant at any time shall be entitled to receive, or shall have received, on the
exercise of the Warrant, in lieu of or in addition to Common Stock, or which at
any time shall be issuable or shall have been issued in exchange for or in
replacement of Common Stock or Other Securities pursuant to Section 4 or
otherwise.

     

    (d)           The
term “Warrant Shares”
shall mean the Common Stock issuable upon exercise of this Warrant.

     

    1.           Exercise of
Warrant.

     

    1.1.           Number of Shares Issuable
upon Exercise.  From and after the Issue Date through and
including the Expiration Date, the Holder hereof shall be entitled to receive,
upon exercise of this Warrant in whole in accordance with the terms of
subsection 1.2 or upon exercise of this Warrant in part in accordance with
subsection 1.3, shares of Common Stock of the Company, subject to
adjustment pursuant to Section 4.

     

    1.2.           Full
Exercise.  This Warrant may be exercised in full by the Holder
hereof by delivery of an original or facsimile copy of the form of subscription
attached as Exhibit A hereto (the “Subscription Form”) duly
executed by such Holder and delivery within two days thereafter of payment, in
cash, wire transfer or by certified or official bank check payable to the order
of the Company, in the amount obtained by multiplying the number of shares of
Common Stock for which this Warrant is then exercisable by the Purchase Price
then in effect.  The original Warrant is not required to be
surrendered to the Company until it has been fully exercised.

     

    1.3.           Partial
Exercise.  This Warrant may be exercised in part (but not for a
fractional share) by delivery of a Subscription Form in the manner and at the
place provided in subsection 1.2 except that the amount payable by the
Holder on such partial exercise shall be the amount obtained by multiplying
(a) the number of whole shares of Common Stock designated by the Holder in
the Subscription Form by (b) the Purchase Price then in
effect.  On any such partial exercise provided the Holder has
surrendered the original Warrant, the Company, at its expense, will forthwith
issue and deliver to or upon the order of the Holder hereof a new Warrant of
like tenor, in the name of the Holder hereof or as such Holder (upon payment by
such Holder of any applicable transfer taxes) may request, the whole number of
shares of Common Stock for which such Warrant may still be
exercised.

     

    1.4.           Fair Market Value.
Fair Market Value of a share of Common Stock as of a particular date (the "Determination Date") shall
mean:

     

    (a)           If
the Company's Common Stock is traded on an exchange or is quoted on the NASDAQ
Global Market, NASDAQ Global Select Market, the NASDAQ Capital Market, the New
York Stock Exchange or the American Stock Exchange, LLC, then the average of the
closing sale prices of the Common Stock for the five (5) Trading Days
immediately prior to (but not including) the Determination Date;

     

    (b)           If
the Company's Common Stock is not traded on an exchange or on the NASDAQ Global
Market, NASDAQ Global Select Market, the NASDAQ Capital Market, the New York
Stock Exchange or the American Stock Exchange, Inc., but is traded on the OTC
Bulletin Board or in the over-the-counter market or Pink Sheets, then the
average of the closing bid and ask prices reported for the five (5) Trading Days
immediately prior to (but not including) the Determination Date;

     

    (c)           Except
as provided in clause (d) below and Section 3.1, if the Company's Common
Stock is not publicly traded, then as the Holder and the Company agree, or in
the absence of such an agreement, by arbitration in accordance with the rules
then standing of the American Arbitration Association, before a single
arbitrator to be chosen from a panel of persons qualified by education and
training to pass on the matter to be decided; or

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

     

    (d)           If
the Determination Date is the date of a liquidation, dissolution or winding up,
or any event deemed to be a liquidation, dissolution or winding up pursuant to
the Company's charter, then all amounts to be payable per share to holders of
the Common Stock pursuant to the charter in the event of such liquidation,
dissolution or winding up, plus all other amounts to be payable per share in
respect of the Common Stock in liquidation under the charter, assuming for the
purposes of this clause (d) that all of the shares of Common Stock then
issuable upon exercise of all of the Warrants are outstanding at the
Determination Date.

     

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

     

    1.6.           Delivery of Stock
Certificates, etc. on Exercise. The Company agrees that, provided the
full purchase price listed in the Subscription Form is received as specified in
Section 1.2, the shares of Common Stock purchased upon exercise of this Warrant
shall be deemed to be issued to the Holder hereof as the record owner of such
shares as of the close of business on the date on which delivery of a
Subscription Form shall have occurred and payment made for such shares as
aforesaid. As soon as practicable after the exercise of this Warrant in full or
in part, and in any event within three (3) business days thereafter (“Warrant Share Delivery Date”),
the Company at its expense (including the payment by it of any applicable issue
taxes) will cause to be issued in the name of and delivered to the Holder
hereof, or as such Holder (upon payment by such Holder of any applicable
transfer taxes) may direct in compliance with applicable securities laws, a
certificate or certificates for the number of duly and validly issued, fully
paid and non-assessable shares of Common Stock (or Other Securities) to which
such Holder shall be entitled on such exercise, plus, in lieu of any fractional
share to which such Holder would otherwise be entitled, cash equal to such
fraction multiplied by the then Fair Market Value of one full share of Common
Stock, together with any other stock or other securities and property (including
cash, where applicable) to which such Holder is entitled upon such exercise
pursuant to Section 1 or otherwise.  The Company understands that
a delay in the delivery of the Warrant Shares after the Warrant Share Delivery
Date could result in economic loss to the Holder.  As compensation to
the Holder for such loss, the Company agrees to pay (as liquidated damages and
not as a penalty) to the Holder for late issuance of Warrant Shares upon
exercise of this Warrant the proportionate amount of $100 per business day after
the Warrant Share Delivery Date for each $10,000 of Purchase Price of Warrant
Shares for which this Warrant is exercised which are not timely
delivered.  The Company shall pay any payments incurred under this
Section in immediately available funds upon demand.  Furthermore, in
addition to any other remedies which may be available to the Holder, in the
event that the Company fails for any reason to effect delivery of the Warrant
Shares by the Warrant Share Delivery Date, the Holder may revoke all or part of
the relevant Warrant exercise by delivery of a notice to such effect to the
Company, whereupon the Company and the Holder shall each be restored to their
respective positions immediately prior to the exercise of the relevant portion
of this Warrant, except that the liquidated damages described above shall be
payable through the date notice of revocation or rescission is given to the
Company.

     

    1.7.           Buy-In.   In
addition to any other rights available to the Holder, if the Company fails to
deliver to a Holder the Warrant Shares as required pursuant to this Warrant,
within seven (7) business days after the Warrant Share Delivery Date and the
Holder or a broker on the Holder’s behalf, purchases (in an open market
transaction or otherwise) shares of common stock to deliver in satisfaction of a
sale by such Holder of the Warrant Shares which the Holder was entitled to
receive from the Company (a "Buy-In"), then the Company
shall pay in cash to the Holder (in addition to any remedies available to or
elected by the Holder) the amount by which (A) the Holder's total purchase price
(including brokerage commissions, if any) for the shares of common stock so
purchased exceeds (B) the aggregate Purchase Price of the Warrant Shares
required to have been delivered together with interest thereon at a rate of 15%
per annum, accruing until such amount and any accrued interest thereon is paid
in full (which amount shall be paid as liquidated damages and not as a
penalty).  For example, if a Holder purchases shares of Common Stock
having a total purchase price of $11,000 to cover a Buy-In with respect to
$10,000 of Purchase Price of Warrant Shares to have been received upon exercise
of this Warrant, the Company shall be required to pay the Holder $1,000, plus
interest. The Holder shall provide the Company written notice indicating the
amounts payable to the Holder in respect of the Buy-In.

    2.           Cashless
Exercise.

     

    (a)           This
Warrant may be exercisable in whole or in part for cash only as set forth in
Section 1 above.  Provided, however, and not withstanding anything to
the contrary herein, if at any time beginning one hundred eighty
days  after the Initial Closing Date, there is no effective
registration statement registering, or no current prospectus available for, the
resale of the shares issuable upon exercise of this Warrant, then payment upon
exercise of this Warrant may be made at the option of the Holder either in
(i) cash, wire transfer or by certified or official bank check payable to
the order of the Company equal to the applicable aggregate Purchase Price, (ii)
by delivery of Common Stock issuable upon exercise of the Warrants in accordance
with Section (b) below or (iii) by a combination of any of the
foregoing methods, for the number of Common Stock specified in such form (as
such exercise number shall be adjusted to reflect any adjustment in the total
number of shares of Common Stock issuable to the holder per the terms of this
Warrant) and the holder shall thereupon be entitled to receive the number of
duly authorized, validly issued, fully-paid and non-assessable shares of Common
Stock (or Other Securities) determined as provided herein. Without limiting the
generality of the foregoing, so long as there is an effective registration
statement registering the shares of the Company’s Common Stock issuable upon the
exercise of this Warrant, then payment upon exercise of this Warrant may only be
made by cash as set forth in Section 1 above.

     

    (b)           Subject
to the provisions herein to the contrary, if the Fair Market Value of one share
of Common Stock is greater than the Purchase Price (at the date of calculation
as set forth below), in lieu of exercising this Warrant for cash, the holder may
elect to receive shares equal to the value (as determined below) of this Warrant
(or the portion thereof being cancelled) by delivery of a properly endorsed
Subscription Form delivered to the Company by any means described in Section 13,
in which event the Company shall issue to the holder a number of shares of
Common Stock computed using the following formula:

     

    X=Y (A-B)

              A

                

    
      
        	
                Where

              	
                X=

              	the number of shares of Common Stock to be issued to the
  holder


      

    

    


    
      	
               
      

            	
              Y=

            	
              the
      number of shares of Common Stock purchasable under the Warrant or, if only
      a portion of the Warrant is being exercised, the portion of the Warrant
      being exercised (at the date of such
  calculation)

            


    

     

    
      	
               
      

            	
              A=

            	
              Fair
      Market Value

            


    

     

    
      	
               
      

            	
              B=

            	
              Purchase
      Price (as adjusted to the date of such
  calculation)

            


    

     

    For
purposes of Rule 144 promulgated under the 1933 Act, it is intended, understood
and acknowledged that the Warrant Shares issued in a cashless exercise
transaction in the manner described above 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 pursuant to the
Subscription Agreement.

    3.           Adjustment for
Reorganization, Consolidation, Merger, etc.

     

    3.1.           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 entity, (B) the Company effects any sale of all or
substantially all of its assets in one or
a series of related transactions,  (C)
any tender offer or exchange offer (whether by the
Company or another entity) is completed pursuant to which holders of Common
Stock are permitted to tender or exchange their
shares for other securities, cash or property, (D) the Company
consummates a stock purchase agreement or other business combination (including,
without limitation, a reorganization, recapitalization, or spin-off) with one or
more persons or entities whereby such other persons or entities acquire more
than the 50% of the outstanding shares of Common Stock (not including any shares
of Common Stock held by such other persons or entities making or party to, or
associated or affiliated with the other persons or entities making or party to,
such stock purchase agreement or other business combination), (E) any "person"
or "group" (as these terms are used for purposes of Sections 13(d) and 14(d) of
the 1934 Act) is or shall become the "beneficial owner" (as defined in Rule
13d-3 under the 1934 Act), directly or indirectly, of 50% of the aggregate
Common Stock of the Company, or (F) the Company effects any
reclassification of the Common Stock or any compulsory share exchange
pursuant to which the Common Stock is effectively converted into or
exchanged for other securities, cash or property (in any such
case, a "Fundamental  Transaction"), then, upon
any subsequent exercise of this Warrant, the Holder shall have the
right to receive, for each Warrant Share that would have been issuable upon such
exercise immediately prior to the occurrence of 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 any additional consideration (the
"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 (1) a transaction where the consideration paid to the holders
of the Common Stock consists solely of cash, (2) a “Rule 13e-3 transaction” as
defined in Rule 13e-3 under the 1934 Act, or (3) a transaction involving a
person or entity not traded on a national securities exchange, the Nasdaq Global
Select Market, the Nasdaq Global Market or the Nasdaq Capital
Market, cash equal to the Black-Scholes Value. 
For purposes of any such exercise, the determination of the
Purchase 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 Purchase 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 3.1 and insuring that this Warrant (or any such
replacement security) will be similarly adjusted upon any subsequent transaction
analogous to a Fundamental Transaction.  “Black-Scholes
Value” shall be determined in accordance with the Black-Scholes Option Pricing
Model obtained from the “OV” function on Bloomberg L.P. using (i) a price per
share of Common Stock equal to the VWAP of the Common Stock for the Trading Day
immediately preceding the date of consummation of the applicable Fundamental
Transaction, (ii) a risk-free interest rate corresponding to the U.S. Treasury
rate for a period equal to the remaining term of this Warrant as of the date of
such request and (iii) an expected volatility equal to the 100 day volatility
obtained from the HVT function on Bloomberg L.P. determined as of the Trading
Day immediately following the public announcement of the applicable Fundamental
Transaction.

     

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

    
 

    3.2.           Continuation of
Terms.  Upon any reorganization, consolidation, merger or
transfer (and any dissolution following any transfer) referred to in this
Section 3, this Warrant shall continue in full force and effect and the
terms hereof shall be applicable to the Other Securities and property receivable
on the exercise of this Warrant after the consummation of such reorganization,
consolidation or merger or the effective date of dissolution following any such
transfer, as the case may be, and shall be binding upon the issuer of any Other
Securities, including, in the case of any such transfer, the person acquiring
all or substantially all of the properties or assets of the Company, whether or
not such person shall have expressly assumed the terms of this Warrant as
provided in Section 4.  In the event this Warrant does not
continue in full force and effect after the consummation of the transaction
described in this Section 3, then only in such event will the Company's
securities and property (including cash, where applicable) receivable by the
Holder of the Warrants be delivered to the Trustee as contemplated by
Section 3.2.

     

    3.3           Share
Issuance.  Until the Expiration Date, if the Company shall
issue any Common Stock except for the Excepted Issuances (as defined in the
Subscription Agreement), prior to the complete exercise of this Warrant for a
consideration less than the Purchase Price that would be in effect at the time
of such issue, then, and thereafter successively upon each such issue, the
Purchase Price shall be reduced to such other lower price for then outstanding
Warrants.  For purposes of this adjustment, the issuance of any
security or debt instrument of the Company carrying the right to convert such
security or debt instrument into Common Stock or of any warrant, right or option
to purchase Common Stock shall result in an adjustment to the Purchase Price
upon the issuance of the above-described security, debt instrument, warrant,
right, or option if such issuance is at a price lower than the Purchase Price in
effect upon such issuance and again at any time upon any subsequent issuances of
shares of Common Stock upon exercise of such conversion or purchase rights if
such issuance is at a price lower than the Purchase Price in effect upon such
issuance.  Common Stock issued or issuable by the Company for no
consideration will be deemed issuable or to have been issued for $0.001 per
share of Common Stock.  Upon any reduction of the Purchase Price, the
number of shares of Common Stock that the Holder of this Warrant shall
thereafter, on the exercise hereof, be entitled to receive shall be adjusted to
a number determined by multiplying the number of shares of Common Stock that
would otherwise (but for the provisions of this Section 3.3) be issuable on such
exercise by a fraction of which (a) the numerator is the Purchase Price that
would otherwise (but for the provisions of this Section 3.3) be in effect, and
(b) the denominator is the Purchase Price in effect on the date of such
exercise.

     

    4.           Extraordinary Events
Regarding Common Stock.  In the event that the Company shall
(a) issue additional shares of the Common Stock as a dividend or other
distribution on outstanding Common Stock, (b) subdivide its outstanding
shares of Common Stock, or (c) combine its outstanding shares of the Common
Stock into a smaller number of shares of the Common Stock, then, in each such
event, the Purchase Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Purchase Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Purchase Price then in effect. The
Purchase Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this
Section 4. The number of shares of Common Stock that the Holder of this
Warrant shall thereafter, on the exercise hereof, be entitled to receive shall
be adjusted to a number determined by multiplying the number of shares of Common
Stock that would otherwise (but for the provisions of this Section 4) be
issuable on such exercise by a fraction of which (a) the numerator is the
Purchase Price that would otherwise (but for the provisions of this Section 4)
be in effect, and (b) the denominator is the Purchase Price in effect on the
date of such exercise.

     

    5.           Certificate as to
Adjustments.  In each case of any adjustment or readjustment in
the shares of Common Stock (or Other Securities) issuable on the exercise of the
Warrants, the Company at its expense will promptly cause its Chief Financial
Officer or other appropriate designee to compute such adjustment or readjustment
in accordance with the terms of the Warrant and prepare a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based, including a statement of (a) the
consideration received or receivable by the Company for any additional shares of
Common Stock (or Other Securities) issued or sold or deemed to have been issued
or sold, (b) the number of shares of Common Stock (or Other Securities)
outstanding or deemed to be outstanding, and (c) the Purchase Price and the
number of shares of Common Stock to be received upon exercise of this Warrant,
in effect immediately prior to such adjustment or readjustment and as adjusted

laws, this Warrant, and the rights evidenced hereby, may be transferred by any
registered holder hereof (a "Transferor"). On the surrender

Exhibit B attached hereto (the “Transferor Endorsement Form")
and together with an opinion of counsel reasonably satisfactory to the Company
that the transfer of this Warrant will be in compliance with applicable
securities laws, the Company will issue and deliver to or on the order of the
Transferor thereof a new Warrant or Warrants of like tenor, in the name of the
Transferor and/or the transferee(s) specified in such Transferor Endorsement
Form (each a "Transferee"), calling in the

the Company or, in the case of any such mutilation, on surrender and
cancellation of this Warrant, the Company at its expense, twice only, will
execute and deliver, in lieu thereof, a new Warrant of like tenor.

     

    9.           Registration
Rights.  The Holder of this Warrant has been granted certain

forth in the Subscription Agreement.  The terms of the Subscription
Agreement are incorporated herein by this reference.

     

    10.           Maximum
Exercise.  The Holder shall not be entitled to exercise this
Warrant on an exercise date, in connection with that number of shares of Common
Stock which would be in excess of the sum of (i) the number of shares of
Common Stock beneficially owned by the Holder and its affiliates on an exercise
date, and (ii) the number of shares of Common Stock issuable upon the
exercise of this Warrant with respect to which the determination of this
limitation is being made on an exercise date, which would result in beneficial
ownership by the Holder and its affiliates of more than 4.99% of the outstanding
shares of Common Stock on such date.  For the purposes of the
immediately preceding sentence, beneficial ownership shall be determined in
accordance with Section 13(d) of the 1934 Act and Rule 13d-3
thereunder.  Subject to the foregoing, the Holder shall not be limited
to aggregate exercises which would result in the issuance of more than
4.99%.  The restriction described in this paragraph may be
waived, in whole or in part, upon sixty-one (61) days prior notice from the
Holder to the Company to increase such percentage to up to 9.99%, but not in
excess of 9.99%.  The Holder may decide whether to convert a
Convertible Note or exercise this Warrant to achieve an actual 4.99% or up to
9.99% ownership position as described above, but not in excess of
9.99%.

    11.           Warrant
Agent.  The Company may, by written notice to the Holder of the
Warrant, appoint an agent (a “Warrant Agent”) for the
purpose of issuing Common Stock (or Other Securities) on the exercise of this
Warrant pursuant to Section 1, exchanging this Warrant pursuant to
Section 7, and replacing this Warrant pursuant to Section 8, or any of
the foregoing, and thereafter any such issuance, exchange or replacement, as the
case may be, shall be made at such office by such Warrant Agent.

     

    12.           Transfer on the Company's
Books.  Until this Warrant is transferred on the books of the
Company, the Company may treat the registered holder hereof as the absolute
owner hereof for all purposes, notwithstanding any notice to the
contrary.
