PART II-RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate [x])

(a) The reasons described in Part III of this form could not be eliminated without unreasonable effort or expense.



                (b) The subject report on Form 10-KSB, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date, or the subject quarterly report or transition report on Form 10-Q or distribution report on Form10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and

(c) The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached.


PART IIIBNARRATIVE

BioTime could not file its Annual Report on Form 10-KSB for the year ended December 31, 2006 within the prescribed period because additional information is required by its independent accountants to complete their audit procedures pertaining to BioTime’s financial statements for that fiscal year.

During February 2007, BioTime, Inc. changed independent accountants, dismissing BDO Seidman, LLP ("BDO") and engaging Rothstein, Kass & Company, P.C. (“Rothstein Kass"). As a result, this is the first audit conducted by Rothstein Kass, who had to become familiar with BioTime's business and accounting records, had to analyze accounting issues as they pertain to BioTime's business and operations, and had to review financial statements, accounting information, contracts and other documentation of BioTime's operations for prior periods, all for the first time, in order to plan and conduct its audit, conduct the reviews required by their audit procedures, and issue a report on BioTime's financial statements. Because this was the first audit by Rothstein Kass it was necessary for their review and verification to be more extensive for this accounting period than might have been the case had they conducted audits for prior periods and reviewed the pertinent accounting data and documentation at that time. As a result it was necessary for BioTime to assemble and provide Rothstein Kass with extensive documentation.

BioTime expects that its independent accountants will be able to complete their audit, and that BioTime will be able to file its Form 10-KSB, by the fifteenth calendar day following the prescribed due date.

This letter is written in response to the requirement of Rule 12b-25(c) under the Securities Exchange Act of 1934 and in satisfaction of item (c) of Part II of Form 12b-25.
 
We are the independent auditors of BioTime, Inc. (the “Registrant”). The Registrant has stated in Part III of its filing on Form 12b-25 that it is unable to timely file, without unreasonable effort or expense, its Annual Report on Form 10-KSB for the year ended December 31, 2006 because our Firm has not yet completed our audit of the financial statements of the Registrant for the year ended December 31, 2006 and is therefore unable to furnish the required opinion on such financial statements.
 
We hereby advise you that we have read the statements made by the Registrant in Part III of its filing on Form 12b-25 and agree with the statements made therein. We were first engaged as the Registrant’s auditors on February 15, 2007. We are unable to complete our audit of the Registrant’s financial statements and furnish the required opinion for a timely filing because additional time is required by us to complete our audit procedures and, as a result, have not yet had sufficient time to complete the auditing procedures that we consider necessary in the circumstances.
 
Very truly yours,
 
/s/ Rothstein, Kass & Company, P.C.
