    (c)           “Maturity Date” means (i)
April 15, 2009 with respect to any Note issued for an additional Loan commitment
under this Fourth Amendment, (ii) April 15, 2009 with respect to any Note issued
under the Third Amended and Restated Credit Agreement or an earlier amendment of
the Credit Agreement, if the Lender has signed an Amendment of Revolving Credit
Note extending the Maturity Date, or (iii) November 15, 2008 with respect to any
Note issued under the Third Amended and Restated Credit Agreement or an earlier
amendment of the Credit Agreement as to which clause (ii) does not
apply.

    


    (d)           “Note” means (a) each
promissory note evidencing a portion of the Loan previously advanced by certain
Lenders, and (b) each Revolving Credit Note in the form attached as EXHIBIT A-1
evidencing the new Loan amounts to be advanced by certain Lenders.

    


    (e)           “Security Agreement” means

obligations under this Agreement and the Note.

    


    2.           Maximum Loan
Amount.  The Maximum Loan Amount shall be Three Million Five
Hundred Thousand Dollars ($3,500,000).

    


    3.           Draw Period.  The
Draw Period shall end on April 15, 2009.


    
      
         


      

      
         


        
          

        

      

      
         


      

    


    4.           Extension of Maturity
Date.  Any Lender holding a Note due November 15, 2008 may
extend the Maturity Date of that Note to April 15, 2009 by executing and
delivering to Borrower an Amendment of Revolving Credit Note in the form of
Exhibit B.

    


    5.           Earmarked Funds; Mandatory

Shares on the OTCBB on the last day on which a closing price of the Shares was
reported prior to the date on which the Lender executed and delivered this
Fourth Amendment.

Current Disclosure Documents were prepared in accordance with generally accepted

financial condition and results of operations of Borrower at and as of the dates
reported.  All financial information and other information contained
in the Current Disclosure Documents was true and correct in all material
respects when such reports were filed under the Exchange Act.

    REVOLVING CREDIT
NOTE

    


    


    


    $___________ __________,
2008

    


    FOR VALUE
RECEIVED, the undersigned, BioTime, Inc., a California corporation (Borrower")
hereby promises to pay to the order of ___________("Lender") the principal sum
of _____________ DOLLARS ($_______________) or such lesser amount as may from
time to time be outstanding as the Loan pursuant to that certain Fourth
Amendment of Revolving Line of Credit Agreement, dated ________________, ___,
2008, between Borrower and Lender, together with interest on the unpaid balance
of the Loan at the rate or rates hereinafter set forth.  This
Revolving Credit Note is one of the Notes described in the Fourth Amendment of
Revolving Line of Credit Agreement.  As used in this Note the term
“Credit Agreement” means the Third Amended and Restated Revolving Line of Credit
Agreement, dated March 31, 2008, as amended by the Fourth Amendment of Revolving
Line of Credit Agreement.  All capitalized terms not otherwise defined
in this Note shall have the meanings defined in the Credit
Agreement.

    


    1.           Terms
of Payment.

    


    (a)           Interest
Rate.  Interest shall accrue and be payable at the rate of 12%
per annum on the outstanding principal balance of the Loan.  Interest
shall accrue from the date of each disbursement of principal pursuant to a
Draw.  Accrued interest shall be paid with principal. Interest will be
charged on that part of outstanding principal of the Loan which has not been
paid and shall be calculated on the basis of a 360-day year and a 30-day
month.

    


    (b)           Payments of
Principal.  The outstanding principal balance of the Loan,
together with accrued interest, shall be paid in full on the Maturity
Date.

    


    (c)           Optional Prepayment of
Principal.  Borrower may prepay principal, with accrued
interest, at any time and the amount of principal so prepaid shall be available
for further Draws by Borrower during the Draw Period.

    


    (d)           Default Interest
Rate.  In the event that any payment of principal or interest
is not paid within five (5) days from on the date on which the same is due and
payable, such payment shall continue as an obligation of the Borrower, and
interest thereon from the due date of such payment and interest on the entire
unpaid balance of the Loan shall accrue until paid in full at the lesser of (i)
fifteen percent (15%) per annum, or (ii) the highest interest rate permitted
under applicable law (the "Default Rate").  From and after the
Maturity Date or upon acceleration of the Note, the entire unpaid principal
balance of the Loan with all unpaid interest accrued thereon, and any and all

or assets; (h) the appointment of any receiver, trustee, custodian, conservator,

part of the property or assets of Borrower, without the application or consent
of Borrower, if such appointment continues undischarged or unstayed for sixty
(60) calendar days; (i) Borrower instituting or consenting to any proceeding
under any Debtor Relief Law with respect to Borrower or all or any part of its

applicable liquidation, conservatorship, bankruptcy, moratorium, rearrangement,
receivership, insolvency, reorganization, or similar debtor relief law affecting

    3.           Remedies On
Default.  Upon the occurrence of an Event of Default, at
Lender's option, all unpaid principal and accrued interest, and all other
amounts payable under this Note shall become immediately due and payable without
presentment, demand, notice of non

    payment,
protest, or notice of non-payment.  Lender also shall have all other
rights, powers, and remedies available under the Credit Agreement and any other
Loan Document, or accorded by law or at equity.  All rights, powers,
and remedies of Lender may be exercised at any time by Lender and from time to
time after the occurrence of an Event of Default.  All rights, powers,
and remedies of Lender in connection with this Note and any other Loan Document
are cumulative and not exclusive and shall be in addition to any other rights,
powers, or remedies provided by law or equity.

    


    4.           Miscellaneous.

    


    (a)           Borrower
and all guarantors and endorsers of this Note severally waive (i) presentment,
demand, protest, notice of dishonor, and all other notices; (ii) any release or
discharge arising from any extension of time, discharge of a prior party,
release of any or all of the security for this Note, and (iii) any other cause
of release or discharge other than actual payment in full of all indebtedness
evidenced by or arising under this Note.

    


    (b)           No
delay or omission of Lender to exercise any right, whether before or after an
Event of Default, shall impair any such right or shall be construed to be a
waiver of any right or default, and the acceptance of any past-due amount at any
time by the Lender shall not be deemed to be a waiver of the right to require
prompt payment when due of any other amounts then or thereafter due and
payable.  The Lender shall not be deemed, by any act or omission, to
have waived any of Lender's rights or remedies under this Note unless such
waiver is in writing and signed by Lender and then only to the extent
specifically set forth in such writing.  A waiver with reference to
one event shall not be construed as continuing or as a bar to or waiver of any
right or remedy as to a subsequent event.

    


    (c)           Lender
may accept, indorse, present for payment, and negotiate checks marked "payment
in full" or with words of similar effect without waiving Lender's right to
collect from Borrower the full amount owed by Borrower.

    


    (d)           Time is of the essence under this
Note.  Upon any Event of Default, the Lender may exercise all
rights and remedies provided for in this Note and by law, including, but not
limited to, the right to immediate payment in full of this Note.

    


    (e)           The
rights and remedies of the Lender as provided in this Note, in the Credit
Agreement, and in the Security Agreement and in law or equity, shall be
cumulative and concurrent, and may be pursued singularly, successively, or
together at the sole discretion of the Lender, and may be exercised as often as
occasion therefor shall occur; and the failure to exercise any such right or
remedy shall in no event be construed as a waiver or a release of any such right
or remedy.

    


    (f)           It
is expressly agreed that if this Note is referred to an attorney or if suit is
brought to collect this Note or any amount due under this Note, or to enforce or
protect any rights conferred upon Lender by this Note then Borrower promises and
agrees to pay on demand all costs, including without limitation, reasonable
attorneys' fees, incurred by Lender in the enforcement of Lender's rights and
remedies under this Note, and such other agreements.

    (g)           The
terms, covenants, and conditions contained in this Note shall be binding upon
the heirs, executors, administrators, successors, and assigns of Borrower, and
each of them, and shall inure to the benefit of the heirs, executors,

    (h)           This
Note shall be construed under and governed by the laws of the State of
California without regard to conflicts of law.

    


    (i)           No
provision of this Note shall be construed or so operate as to require the
Borrower to pay interest at a greater rate than the maximum allowed by
applicable state or federal law.  Should any interest or other charges
paid or payable by the Borrower in connection with this Note or the Loan result
in the computation or earning of interest in excess of the maximum allowed by
applicable state or federal law, then any and all such excess shall be and the
same is hereby waived by Lender, and any and all such excess paid shall be
credited automatically against and in reduction of the outstanding principal
balance due of the Loan, and the portion of said excess which exceeds such
principal balance shall be paid by Lender to the Borrower.
