NOTES TO CONDENSED INTERIM FINANCIAL STATEMENTS (UNAUDITED)

1. Description of Organization

General - BioTime, Inc. (“BioTime”) was organized November 30, 1990 as a California corporation. BioTime is a biomedical organization which is engaged in the research and development of synthetic plasma expanders, blood volume substitute solutions, and organ preservation solutions, for use in surgery, trauma care, organ transplant procedures, and other areas of medicine.

The unaudited condensed interim balance sheet as of June 30, 2007, and the unaudited condensed interim statements of operations and cash flows for the three and six months ended June 30, 2007 and 2006 have been prepared by BioTime management. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows at June 30, 2007 and for all interim periods presented have been made. The results of operations for the three and six months ended June 30, 2007 are not necessarily indicative of the operating results anticipated for the full year.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted as permitted by regulations of the Securities and Exchange Commission. Certain previously furnished amounts have been reclassified to conform with presentations made during the current periods. It is suggested that these condensed interim financial statements be read in conjunction with the annual audited financial statements and notes thereto included in BioTime's Form 10-K for the year ended December 31, 2006.

Significant Risks and Uncertainties- BioTime's operations are subject to a number of factors that can affect its operating results and financial condition. Such factors include but are not limited to the following: the results of clinical trials of BioTime's products; BioTime's ability to obtain United States Food and Drug Administration and foreign regulatory approval to market its products; competition from products manufactured and sold or being developed by other companies; the price of and demand for BioTime products; BioTime's ability to obtain additional financing and the terms of any such financing that may be obtained; BioTime's ability to negotiate favorable licensing or other manufacturing and marketing agreements for its products; the availability of ingredients used in BioTime's products; and the availability of reimbursement for the cost of BioTime's products (and related treatment) from government health administration authorities, private health coverage insurers and other organizations.

Liquidity and Going Concern - The accompanying condensed interim financial statements have been prepared assuming BioTime will continue as a going concern. At June 30, 2007, BioTime had $127,242 cash on hand and lines of credit for $573,600 (see Note 3), from which $300,000 had been drawn at June 30, 2007. BioTime also had negative working capital of $759,200, a shareholders' deficit of $2,636,640, and an accumulated deficit of $43,304,210. BioTime needs additional capital and greater revenues to continue its current operations, and to conduct its planned product development and research programs. Sales of additional equity securities could result in the dilution of the interests of present shareholders. BioTime is also continuing to seek new agreements with pharmaceutical companies to provide product and technology licensing fees and royalties. The availability and terms of equity financing and new license agreements are uncertain. The unavailability or inadequacy of additional financing or future revenues to meet capital needs could force BioTime to modify, curtail, delay, suspend, or possibly discontinue some or all aspects of its planned operations. Management believes that its projected rate of spending, which includes possible spending cuts, cash on hand, anticipated royalties from the sale of Hextend^® , licensing fees, and available revolving lines of credit, will allow BioTime to operate through September 30, 2007. These conditions raise substantial doubt about BioTime's ability to continue as a going concern. The accompanying condensed interim financial statements do not include any adjustments that might result from the outcome of this uncertainty.

2. Summary of Significant Accounting Policies

Financial Statement Estimates - The preparation of condensed interim financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition - Royalty and license fee revenues consist of product royalty payments and fees under license agreements and are recognized when earned. Up-front nonrefundable fees where BioTime has no continuing performance obligations are recognized as revenues when collection is reasonably assured. In situations where continuing performance obligations exist, up-front nonrefundable fees are deferred and amortized ratably over the performance period. If the performance period cannot be reasonably estimated, BioTime amortizes nonrefundable fees over the life of the contract until such time that the performance period can be more reasonably estimated. Milestones, if any, related to scientific or technical achievements are recognized in income when the milestone is accomplished if (a) substantive effort was required to achieve the milestone, (b) the amount of the milestone payment appears reasonably commensurate with the effort expended and (c) collection of the payment is reasonably assured.

BioTime also defers costs, including finders' fees, which are directly related to license agreements for which revenue has been deferred. Deferred costs are charged to expense proportionally and over the same period that related deferred revenue is recognized as revenue. Deferred costs are net against deferred revenues in BioTime's balance sheet.

BioTime recognizes royalty revenues in the quarter in which the sales report is received, rather than the quarter in which the sales took place, as BioTime does not have sufficient sales history to accurately predict quarterly sales.

Grant income is recognized as revenue when earned.

Indemnification - The following is a summary of BioTime's agreements that BioTime has determined are within the scope of the Financial Accounting Standards Board (the “FASB”) interpretation No. 45 (“FIN 45”), "Guarantor's Accounting and Disclosure Requirements for Guarantees, including Indirect Guarantees of Indebtedness of Others -- an interpretation of FASB Statements No. 5, 57 and 107 and rescission of FIN 34."

Under its bylaws, BioTime has agreed to indemnify its officers and directors for certain events or occurrences arising as a result of the officer or director's serving in such capacity. The term of the indemnification period is for the officer's or director's lifetime. The maximum potential amount of future payments BioTime could be required to make under the indemnification provisions contained in its bylaws is unlimited. However, BioTime has a directors' and officers' liability insurance policy that limits its exposure and enables it to recover a portion of any future amounts paid. As a result of its insurance policy coverage, BioTime believes the estimated fair value of these indemnification agreements is minimal and has no liabilities recorded for these agreements as of June 30, 2007.

Under its license agreements with Hospira, Inc. ("Hospira") and CJ Corp. ("CJ"), BioTime shall indemnify Abbott (Hospira's predecessor in interest), Hospira, and/or CJ for any cost or expense resulting from any third party claim or lawsuit arising from alleged patent infringement by Abbott, Hospira, or CJ relating to actions covered by the applicable license agreement. Management believes that the possibility of payments under the indemnification clauses by BioTime is remote. Therefore, BioTime has not recorded a provision for potential claims as of June 30, 2007.

BioTime enters into indemnification provisions under (i) its agreements with other companies in its ordinary course of business, typically with business partners, licensees, contractors, hospitals at which clinical studies are conducted, and landlords and (ii) its agreements with investors, investment bankers and financial advisers. Under these provisions BioTime generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of BioTime's activities or, in some cases, as a result of the indemnified party's activities under the agreement. These indemnification provisions often include indemnifications relating to representations made by BioTime with regard to intellectual property rights. These indemnification provisions generally survive termination of the underlying agreement. In some cases, BioTime has obtained liability insurance providing coverage that limits its exposure for indemnified matters. The maximum potential amount of future payments BioTime could be required to make under these indemnification provisions is unlimited. BioTime has not incurred material costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, BioTime believes the estimated fair value of these agreements is minimal. Accordingly, BioTime has no liabilities recorded for these agreements as of June 30, 2007.

Stock-Based Compensation - On January 1, 2006, BioTime adopted Statement of Financial Accounting Standards (“SFAS”) No. 123 (Revised 2004), “Share-Based Payment” (“SFAS 123(R)”) which requires the measurement and recognition of compensation expense for all share-based payment awards made to directors and employees including employee stock options based on estimated fair values. SFAS 123(R) supersedes BioTime's previous accounting policy using the intrinsic value method under Accounting Principles Board Opinion (“APB”) No. 25, “Accounting for Stock Issued to Employees” for periods beginning in fiscal 2006. In March 2005, the Securities and Exchange Commission issued Staff Accounting Bulletin (“SAB”) No. 107, “Valuation of Share-Based Payment Arrangements for Public Companies”, which provides supplemental implementation guidance for SFAS 123(R). BioTime has applied the provisions of SAB 107 in its adoption of SFAS 123(R). Upon adoption of SFAS 123(R), BioTime has continued to utilize the Black-Scholes Merton option pricing model which was previously used for BioTime's pro forma disclosures under SFAS 123. BioTime's determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by BioTime's stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, BioTime's expected stock price volatility over the term of the awards, and the actual and projected employee stock options exercise behaviors. The expected term of options granted is derived from historical data on employee exercises and post-vesting employment termination behavior. The risk-free rate is based on the U.S Treasury rates in effect during the corresponding period of grant. Because changes in the subjective assumptions can materially affect the estimated value, in management's opinion, the existing valuation models may not provide an accurate measure of the fair value of BioTime's employee stock options. Although the fair value of employee stock options is determined in accordance with SFAS 123(R) and SAB 107 using an option-pricing model, that value may not be indicative of the fair value observed in a willing buyer/willing seller market transaction. See Note 8 for additional information.

Recently Adopted Accounting Standards - In July 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (“FIN 48”). FIN 48 creates a single accounting and disclosure model for uncertain tax positions, provides guidance on the minimum threshold that a tax uncertainty is required to meet before it can be recognized in the financial statements, and applies to all tax positions taken by a company, both those deemed to be routine as well as those for which there may be a high degree of uncertainty.

FIN 48 establishes a two-step approach for evaluating tax positions. The first step – recognition – occurs when a company concludes (based solely on the technical aspects of the tax matter) that a tax position is more likely than not to be sustained on examination by a taxing authority. The second step – measurement – is only considered after step one has been satisfied, and measures any tax benefit at the largest amount that is deemed more likely than not to be realized upon ultimate settlement of the uncertainty. Tax positions that fail to qualify for initial recognition are recognized in the first subsequent interim period that they meet the more likely than not standard, when they are resolved through negotiation or litigation with the taxing authority, or upon the expiration of the statute of limitations. Derecognition of a tax position previously recognized would occur when a company subsequently concludes that a tax position no longer meets the more likely than not threshold of being sustained. FIN 48 also significantly expands the financial statement disclosure requirements relating to uncertain tax positions. FIN 48 is effective for fiscal years beginning after December 15, 2006. Differences between the amounts recognized in the balance sheet prior to adoption and the amounts recognized in the balance sheet after adoption will be accounted for as a cumulative effect adjustment to the beginning balance of retained earnings. BioTime does not believe that the adoption of FIN 48 will have a material effect on its condensed interim financial statements.

Recently Issued Accounting Standards

In September 2006, the FASB issued SFAS 157, “Fair Value Measurements,” which defines fair value, establishes a framework for measuring fair value, and requires additional disclosures about fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007. BioTime is currently evaluating the effect, if any, that the adoption of SFAS 157 will have on its condensed interim financial statements.

In September 2006, the Securities and Exchange Commission issued SAB No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements” (“SAB 108”). SAB 108 provides guidance on how prior year misstatements should be considered when quantifying misstatements in the current year financial statements. The SAB requires registrants to quantify misstatements using both a balance sheet and an income statement approach and evaluate whether either approach results in quantifying a misstatement that, when all relevant quantitative and qualitative factors are considered, is material. SAB 108 does not change the guidance in SAB 99, “Materiality,” when evaluating the materiality of misstatements. SAB 108 is effective for fiscal years ending after November 15, 2006. Upon initial application, SAB 108 permits a one-time cumulative effect adjustment to beginning retained earnings. The Company is currently evaluating the potential impact, if any, that the adoption of SAB 108 will have on its condensed interim financial statements.

In February 2007, the FASB issued SFAS 159, “The Fair Value Option for Financial Assets and Financial Liabilities.” SFAS 159 permits entities to choose to measure many financial instruments, and certain other items, at fair value. SFAS 159 applies to reporting periods beginning after November 15, 2007. BioTime is currently evaluating the effect, if any, that the adoption of SFAS 159 will have on its condensed interim financial statements.

3. Lines of Credit

In April 2006, BioTime entered into a Revolving Line of Credit Agreement (the “Credit Agreement”) with Alfred D. Kingsley, Cyndel & Co., Inc., and George Karfunkel, investors in BioTime, under which BioTime may borrow up to $500,000 for working capital purposes at an interest rate of 10% per annum. The maturity date of the Credit Agreement is the earlier of (i) October 31, 2007 or (ii) such date on which the borrower shall have received an aggregate of $600,000 through (A) the sale of capital stock, (B) the collection of licensing fees, signing fees, milestone fees, or similar fees in excess of $1,000,000 under any present or future agreement pursuant to which the borrower grants one or more licenses to use the borrower's patents or technology, (C) funds borrowed from other lenders, or (D) any combination of sources under clauses (A) through (C). Under the Credit Agreement, BioTime will prepay, and the credit line will be reduced by, any funds received prior to the maturity date from those sources discussed above. In consideration for making the line of credit available, BioTime issued to the investors a total of 99,999 common shares. The line of credit is collateralized by a security interest in BioTime's right to receive royalty and other payments under the license agreement with Hospira. The market value of BioTime common shares was $0.38 per common share on April 12, 2006, valuing the shares at $38,000. During the six months ended June 30, 2007, BioTime drew $300,000 under this line of credit.

BioTime also has an available line of credit from American Express, which allows for borrowings up to $43,600; no funds have yet been drawn from this line of credit. Should any such money be drawn, interest will be payable on borrowings at a total rate equal to the prime rate plus 3.99% per annum; however, regardless of the prime rate, the interest rate payable will at no time be less than 9.49% per annum. The line of credit will not expire unless terminated by one of the parties.

BioTime also secured a line of credit from Advanta in November 2006, which allows for borrowings up to $30,000; no funds have yet been drawn from this line of credit. Should any such money be drawn, interest will be payable on borrowings at a Variable Rate Index, which will at no time be less than 8.25% per annum.

4. Royalty Obligation

In December 2004, BioTime entered into an agreement with Summit Pharmaceuticals International Corporation (“Summit”) to co-develop Hextend and PentaLyte for the Japanese market. Under the agreement, BioTime received $300,000 in December 2004, $450,000 in April 2005, and $150,000 in October 2005. The payments represent a partial reimbursement of BioTime's development costs of Hextend and PentaLyte. In June 2005, following BioTime's approval of Summit's development plan for Hextend, BioTime paid to Summit a one-time fee of $130,000 for their services in preparing the plan. The agreement states that revenues from Hextend and PentaLyte in Japan will be shared between BioTime and Summit as follows: BioTime 40% and Summit 60%. Additionally, BioTime will pay Summit 8% of all net royalties received from the sale of PentaLyte in the United States.

The accounting treatment of the payments from Summit falls under the guidance of Emerging Issues Task Force (“EITF”) 88-18, “Sales of Future Revenues.” EITF 88-18 addresses the accounting treatment when an enterprise (BioTime) receives cash from an investor (Summit) and agrees to pay to the investor a specified percentage or amount of the revenue or a measure of income of a particular product line, business segment, trademark, patent, or contractual right. The EITF reached a consensus on six independent factors that would require reclassification of the proceeds as debt. BioTime meets one of the factors whereby BioTime has significant continuing involvement in the generation of the cash flows due to the investor. As a result, BioTime initially recorded the net proceeds from Summit to date of $770,000 as long-term debt to comply with EITF 88-18, even though BioTime is not legally indebted to Summit for that amount.

In July 2005, Summit sublicensed the rights to Hextend in Japan to Maruishi Pharmaceutical Co., Ltd (“Maruishi”). In consideration for the license, Maruishi agreed to pay Summit a series of milestone payments: Yen 70,000,000, (or $593,390 USD based on foreign currency conversion rates at the time) upon executing the agreement, Yen 100,000,000 upon regulatory filing in Japan, and Yen 100,000,000 upon regulatory approval of Hextend in Japan. Consistent with the terms of the BioTime and Summit agreement, Summit paid 40% of the initial agreement execution amount, $237,356, to BioTime during October 2005. BioTime does not expect the regulatory filing and approval milestones to be attained for several years.

The initial accounting viewed the potential repayment of the $770,000 imputed debt to come only from the 8% share of US PentaLyte revenues generated by BioTime and paid to Summit. BioTime first became aware of the terms of the Maruishi sublicense during the fourth quarter of 2005, at which time BioTime prepared an estimate of the future cash flows, and determined that Summit will earn a majority of its return on investment from its agreement with Maruishi, and not the 8% of BioTime's U.S. PentaLyte sales. Considering this, the imputed $770,000 obligation to Summit is viewed for accounting purposes as a royalty obligation which will be reduced by Summit's 8% share of BioTime's U.S. PentaLyte sales plus Summit's 60% share of Japanese revenue. Accordingly, BioTime recorded the entire $593,390 paid by Maruishi to Summit for the sublicense as deferred revenue, to be amortized over the remaining life of the patent through 2019. BioTime's 40% share of this payment was collected in October 2005 and the remaining 60% share was recorded as a reduction of the long-term royalty obligation of BioTime to Summit. The balance of the license fees received by BioTime is still being treated as a long-term royalty obligation for financial accounting purposes under EITF 88-18. Interest on the long-term royalty obligation is accrued monthly, using the effective interest method beginning October 2005, at the rate of 25.2% per annum, which BioTime has determined is the appropriate interest rate when the future cash flows from the transaction are considered. The effective interest rate will be evaluated annually, or when events occur that have significantly affected the estimate of future cash flows. BioTime has recorded $83,438 and $65,484 of interest expense on the long-term royalty obligation during the six months ended June 30, 2007 and June 30, 2006, respectively.

5. Shareholders' Deficit

During April 1998, BioTime entered into a financial advisory services agreement with Greenbelt Corp. ("Greenbelt"), a corporation controlled by Alfred D. Kingsley and Gary K. Duberstein, who are also shareholders of BioTime. The agreement has been renewed each subsequent year ending March 31. For the twelve months ended March 31, 2006, BioTime agreed to pay Greenbelt $45,000 in cash and issue 135,000 common shares. During March 2006, the board of directors approved the renewal of the agreement with Greenbelt for the 12 months ended March 31, 2007. BioTime will pay Greenbelt a cash fee of $90,000 and agreed to issue Greenbelt 200,000 common shares. The cash fees were payable as follows: $30,000 on January 2, 2007, $30,000 on April 2, 2007, and $30,000 on October 1, 2007. However, BioTime elected to exercise its right to defer the cash payments that would otherwise have been due on January 2, 2007 and April 2, 2007. The deferred payments must be paid no later than October 1, 2007. Under the terms of the Greenbelt agreement, BioTime issued to Greenbelt 60,000 additional common shares as consideration for the deferral of the cash payments. The condensed interim statement of operations for the six months ended June 30, 2007 reflects an expense of $33,000 as the value of the 60,000 shares issued to Greenbelt as consideration for the deferral of the payments due January 2, 2007 and April 2, 2007.

Activity related to the Greenbelt agreement is presented in the table below:

	Balance included in Accounts Payable at January 1,	Add: Cash-based expense accrued	Add: Stock-based expense accrued	Less: Cash payments	Less: Value of stock-based payments	Balance included in Accounts Payable at June 30,

2006	$ 65,138	33,750	23,487	(45,000)	(43,875)	$33,500

During the three months ended June 30, 2007 and 2006, BioTime issued to Greenbelt 110,000 and 135,000 common shares, valued at $62,500 and $43,875, respectively.

During the six months ended June 30, 2006, 63 warrants were exercised for proceeds of $126.

6. Licensing Agreement

On March 24, 2006, BioTime entered into a license agreement with Summit to develop Hextend and PentaLyte in the People's Republic of China, and Taiwan. Summit paid BioTime $500,000 in May 2006 as the initial consideration for the China and Taiwan license. BioTime also will be entitled to receive 50% of the royalties and any milestone payments received by Summit from any third-party sublicense, excluding the first payment made by a sublicensee upon execution of an agreement with Summit. Summit has entered a sublicense agreement with Maruishi for Hextend and PentaLyte in China and Taiwan. Milestone payments of Yen 20,000,000 are payable by Maruishi when the first new drug application for Hextend is filed and when the first clinical study of PentaLyte begins under the sublicense.

7. Net Loss Per Share

Basic loss per share excludes dilution and is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted loss per share reflects the potential dilution from securities and other contracts which are exercisable or convertible into common shares. For the three and six months ended June 30, 2007 and 2006, options to purchase 1,691,644 and 1,479,644 common shares, respectively, and warrants to purchase 7,847,867 and 7,847,867 common shares, respectively, were excluded from the computation of earnings (loss) per share as their inclusion would be antidilutive. As a result, there is no difference between basic and diluted calculations of loss per share for all periods presented.

8. Stock-Based Compensation

On January 1, 2006, BioTime adopted SFAS 123(R), which requires the measurement and recognition for all share-based payment awards made to BioTime's employees and directors including employee stock options. The following table summarizes stock-based compensation expense related to employee and director stock options awards for the three and six months ended June 30, 2007 and 2006 which was allocated as follows:

	Three Months Ended June 30, 2007 (under SFAS 123(R))		Six Months Ended June 30, 2007 (under SFAS 123(R))		Three Months Ended June 30, 2006 (under SFAS 123(R))		Six Months Ended June 30, 2006 (under SFAS 123(R))
Stock-based compensation expense:

Research and Development	$	-	$	-	$	-	$	-
General and Administrative		17,483		23,520		16,968		35,811

Stock-based compensation expense included in operating expense		17,483		23,520		16,968		35,811

Total stock-based compensation expense	$	17,483	$	23,520	$	16,968	$	35,811

The value of each employee and director stock option was estimated on the date of grant using the Black-Scholes Merton model for the purpose of the pro forma financial disclosures in accordance with SFAS 123(R).

The weighted-average estimated fair value of stock options granted during the six months ended June 30, 2007 and 2006 was $0.57 and $0.25 per share, respectively, using the Black-Scholes Merton model with the following weighted-average assumptions:

	Six Months Ended			Six Months Ended
	June 30, 2007			June 30, 2006
Expected lives in years		5			5
Risk free interest rates		4.51	%		4.79	%
Volatility		102	%		93	%
Dividend yield		0	%		0	%
Forfeiture		0	%		0	%

BioTime uses third-party analyses to assist in developing the assumptions used to determine fair value of share-based payment awards granted. BioTime's determination of the fair value of share-based payment awards on the date of grant using an option-pricing model is affected by BioTime's stock price as well as assumptions regarding a number of highly complex and subjective variables. The variables include, but are not limited to BioTime's expected stock price volatility over the term of the awards, and the actual and projected employee stock option exercise behaviors. Because changes in the subjective assumptions can materially affect the estimated value, in management's opinion, the existing valuation models may not provide an accurate measure of the fair value of BioTime's employee stock options. Although the fair value of employee stock options is determined in accordance with SFAS 123(R) and SAB 107 using an option-pricing model, that value may not be indicative of the fair value observed in a willing buyer/willing seller market transaction.

Item 2. Management's Discussion and Analysis or Plan of Operation.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

Since its inception in November 1990, BioTime has been engaged primarily in research and development activities, which have culminated in the commercial launch of Hextend^®, our lead product, and our recently completed clinical trial of PentaLyte^®. Our operating revenues have been generated primarily from licensing fees and from royalties on the sale of Hextend. Our ability to generate substantial operating revenue depends upon our success in developing and marketing or licensing our plasma volume expanders and organ preservation solutions and technology for medical use.

Most of our research and development efforts have been devoted to our first three blood volume replacement products: Hextend, PentaLyte, and HetaCool^®. By testing and bringing all three products to the market, we can increase our market share by providing the medical community with solutions to match patients' needs. By developing technology for the use of HetaCool in low temperature surgery, trauma care, and organ transplant surgery, we may also create new market segments for our product line.

Our first product, Hextend, is a physiologically balanced blood plasma volume expander, for the treatment of hypovolemia. Hextend is being distributed in the United States by Hospira, Inc. (“Hospira”) and in South Korea by CJ Corp. (“CJ”) under exclusive licenses from us. Hospira also has the right to obtain regulatory approval and market Hextend in Latin America and Australia. Summit Pharmaceuticals International Corporation (“Summit”) has a license to develop Hextend and PentaLyte in Japan, the People's Republic of China, and Taiwan. Summit has entered into sublicenses with Maruishi Pharmaceutical Co., Ltd. (“Maruishi”) to obtain regulatory approval, manufacture, and market Hextend in Japan, and Hextend and PentaLyte in China and Taiwan.

Under our license agreements, Hospira and CJ will report sales of Hextend and pay us the royalties and license fees due on account of such sales after the end of each calendar quarter. We recognize such revenues in the quarter in which the sales report is received, rather than the quarter in which the sales took place.

Revenues for the three months ended June 30, 2007 consist of royalties on sales made by Hospira during the period beginning January 1, 2007 and ending March 31, 2007. Royalty revenues recognized for that three-month period were $163,676 a 64% increase from $99,957 of royalty revenue from Hospira during the same period last year.

Licensee sales to hospitals and to the United States Armed Forces increased during the period. Hextend is part of the Tactical Combat Casualty Care protocol and has been purchased by the Armed Forces through intermittent large volume orders.

We received royalties of $183,093 from Hospira during July 2007, based on Hextend sales during the three months ended June 30, 2007. Royalties decreased 27% from royalty revenues of $250,017 received during the same period last year. The decrease is attributable to a decrease in sales of Hextend to the United States Armed Forces, although this decrease was somewhat offset by an increase in sales to hospitals. This revenue will be reflected in our condensed interim financial statements for the third quarter of 2007.

Hextend has become the standard plasma volume expander at a number of prominent teaching hospitals and leading medical centers. We believe that as Hextend use proliferates within the leading US hospitals, other smaller hospitals will follow their lead contributing to sales growth.

We have completed a Phase II clinical trial of PentaLyte in which PentaLyte was used to treat hypovolemia in cardiac surgery. Our ability to commence and complete additional clinical studies of PentaLyte depends on our cash resources and the costs involved, which are not presently determinable. Clinical trials of PentaLyte in the United States may take longer and may be more costly than the Hextend clinical trials, which cost approximately $3,000,000. The Food and Drug Administration (“FDA”) permitted us to proceed directly into a Phase III clinical trial of Hextend involving only 120 patients because the active ingredients in Hextend had already been approved for use in plasma expanders by the FDA in other products. Because PentaLyte contains a starch (pentastarch) that has not been approved by the FDA for use in a plasma volume expander (although pentastarch is approved in the US for use in certain intravenous solutions used to collect certain blood cell fractions), we had to complete Phase I and Phase II clinical trials of PentaLyte. A subsequent Phase III trial may involve more patients than the Hextend trials, and we do not know yet the actual scope or cost of the clinical trials that the FDA will require for PentaLyte or the other products we are developing.

During April 2007 Hospira declined an opportunity to commercialize PentaLyte^® under the terms we offered. Hospira will continue to manufacture and sell Hextend^® under its License Agreement with us, and we will offer other pharmaceutical companies the opportunity to license PentaLyte^®.

Plasma volume expanders containing pentastarch have been approved for use in certain foreign countries including Canada, certain European Union countries, and Japan. The regulatory agencies in those countries may be more willing to accept applications for regulatory approval of PentaLyte based upon clinical trials smaller in scope than those that may be required by the FDA. This would permit us to bring PentaLyte to market overseas more quickly than in the United States, provided that suitable licensing arrangements can be made with multinational or foreign pharmaceutical companies to obtain financing for clinical trials and manufacturing and marketing arrangements.

We are also continuing to develop solutions for low temperature surgery. Once a sufficient amount of data from successful low temperature surgery has been compiled, we plan to seek permission to use Hextend as a complete replacement for blood under near-freezing conditions. We currently plan to market Hextend for complete blood volume replacement at very low temperatures under the registered trademark “HetaCool®” after FDA approval is obtained, although the time frame for such approval is presently uncertain.

We have been awarded a $299,990 research grant by the NIH for use in the development of HetaCool. We are using the grant to fund a project entitled “Resuscitating Blood-Substituted Hypothermic Dogs” at the Texas Heart Institute in Houston under the guidance of Dr. George V. Letsou. Dr. Letsou is Associate Professor of Surgery and Director of the Heart Failure Center at the University of Texas Medical School in Houston, Texas. We were granted $149,994 for the project during 2004 and $149,996 during 2005. We have received $240,352 of the grant funds through June 30, 2007. In the first quarter of 2007, the time period for drawing down the remainder of the grant funds was extended for another year, running through March 31, 2008.

BioTime scientists believe the HetaCool program has the potential to produce a product that could be used in very high fluid volumes (50 liters or more per procedure if HetaCool were used as a multi-organ donor preservation solution or to temporarily replace substantially all of the patient's circulating blood volume) in cardiovascular surgery, trauma treatment, and organ transplantation. However, the cost and time to complete the development of HetaCool, including clinical trials, cannot presently be determined.

We will depend upon royalties from the sale of Hextend by Hospira and CJ as our principal source of revenues for the foreseeable future. Those royalty revenues will be supplemented by license fees as we enter into new commercial license agreements for our products.

The amount and pace of research and development work that we can do or sponsor, and our ability to commence and complete clinical trials required to obtain FDA and foreign regulatory approval of products, depends upon the amount of money we have. Future research and clinical study costs are not presently determinable due to many factors, including the inherent uncertainty of these costs and the uncertainty as to timing, source, and amount of capital that will become available for these projects. We have already curtailed the pace of our product development efforts due to the limited amount of funds available, and we may have to postpone further laboratory and clinical studies, unless our cash resources increase through growth in revenues, the completion of licensing agreements, additional equity investment, borrowing or third party sponsorship.

Because our research and development expenses, clinical trial expenses, and production and marketing expenses will be charged against earnings for financial reporting purposes, management expects that there will be losses from operations in the near term.

Results of Operations

Revenues

During the three months ended June 30, 2007, we recognized $47,065 of license fee revenues related to the CJ and Summit Agreements. The CJ license fee of $800,000, net of the finder's fees, has been deferred and is being recognized as revenue over the life of the contract, which has been estimated to be approximately eight years based on the current expected life of the patent covering BioTime's products in Korea. A portion of the proceeds received by Summit from Maruishi in conjunction with the sublicense of Hextend have also been deferred and are being amortized under the same terms as the CJ revenues. See Notes 2 and 4 to the condensed interim financial statements.

For the three months ended June 30, 2007, we recognized $163,676 in royalty revenue, whereas we recognized $99,957 for the three months ended June 30, 2006. Licensee sales to hospitals and to the United States Armed Forces increased during the period, reflecting the fact that the Armed Forces purchase Hextend in intermittent large volume orders.

Operating Expenses

Research and development expenses were $210,767 for the three months ended June 30, 2007, compared to $381,996 for the three months ended June 30, 2006. This decrease is chiefly attributable to the completion of our Phase II clinical trials of PentaLyte. Research and development expenses include clinical trials expenses, laboratory study expenses, salaries, ongoing prosecution of regulatory applications in the United States, and consultants' fees. For the six months ended June 30, 2007, research and development expenses totaled $554,317, compared to $649,807 for the six months ended June 30, 2006. This decrease is due primarily to a decrease of approximately $41,000 in consultants’ fees and outside research expenses due to the completion of Phase II clinical trials for PentaLyte in early 2007, a decrease of approximately $37,000 for benefits and employee related costs allocated to research and development, and a decrease of approximately $18,000 for business insurance allocated to research and development.

General and administrative expenses decreased to $293,772 for the three months ended June 30, 2007 from $402,379 for the three months ended June 30, 2006. In an effort to conserve cash, we have continued to cut our expenses, and had cost savings in the following general and administrative expenses: a decrease of approximately $39,000 in costs associated with our 2006 annual meeting (analogous costs have not yet been incurred in 2007), a decrease of approximately $28,000 in accounting services due to change in audit firm, a decrease of approximately $23,000 in investor relation services, and a decrease of approximately $19,000 in consulting expense. For the six months ended June 30, 2007, general and administrative expenses totaled $711,552, compared to $837,381 for the six months ended June 30, 2006. This decrease is due primarily to a decrease of approximately $61,000 in legal and accounting expenses, a decrease of approximately $27,000 in investor relations costs, and a decrease of approximately $40,000 in printing and other costs associated with our annual meeting. These increases were somewhat offset by an increase of approximately $22,000 in patent costs.

Interest Income (Expense) and Other

For the three months ended June 30, 2007, we incurred net interest and other expense of $50,279, compared to $26,664 for the three months ended June 30, 2006. For the six months ended June 30, 2007, we incurred net interest and other expense of $88,509, compared to $43,780 for the six months ended June 30, 2006. These increases are due to higher interest expense associated with our imputed royalty obligation under our license agreement with Summit and interest accrued for the line of credit funds drawn.

Income Taxes

For Federal and state income tax purposes, our effective income tax rate differs from the statutory rate due to the 100% valuation allowance established for our deferred tax assets, which relate primarily to net operating loss carryforwards, as realization of such benefits is not deemed to be likely.

Net Loss

For the three- and six-month periods ended June 30, 2007, our net losses were $344,077 and $897,939, respectively.

Liquidity and Capital Resources

The major components of our net cash used in operations of approximately $350,000 in the second quarter of 2007 can be summarized as follows: we received approximately $164,000 of royalty revenues from Hospira; offsetting this amount were total cash-based research and development expenditures of approximately $216,000, and cash-based general and administrative expenditures of approximately $298,000.

At June 30, 2007, we had $127,242 cash on hand and lines of credit for $573,600, from which $300,000 had been drawn.

We will need to obtain additional equity capital or licensing fees during 2007 to finance our current operations because our current lines of credit and our royalty revenues are not sufficient to fund our operations beyond September 30, 2007.

During April 2007 Hospira declined an opportunity to commercialize PentaLyte^® under the terms we offered. We will offer other pharmaceutical companies the opportunity to license PentaLyte^®.

Since inception, we have primarily financed our operations through the sale of equity securities, licensing fees, royalties on product sales by our licensees, and borrowings. The amount of license fees and royalties that may be earned through the licensing and sale of our products and technology, the timing of the receipt of license fee payments, and the future availability and terms of equity financing, are uncertain. The unavailability or inadequacy of financing or revenues to meet future capital needs could force us to modify, curtail, delay or suspend some or all aspects of our planned operations. Sales of additional equity securities could result in the dilution of the interests of present shareholders.

In April 2006, BioTime entered into a Revolving Line of Credit Agreement (the “Credit Agreement”) with Alfred D. Kingsley, Cyndel & Co., Inc., and George Karfunkel, investors in BioTime, under which BioTime may borrow up to $500,000 for working capital purposes at an interest rate of 10% per annum. The maturity date of the Credit Agreement is the earlier of (i) October 31, 2007 or (ii) such date on which the borrower shall have received an aggregate of $600,000 through (A) the sale of capital stock, (B) the collection of licensing fees, signing fees, milestone fees, or similar fees in excess of $1,000,000 under any present or future agreement pursuant to which the borrower grants one or more licenses to use the borrower's patents or technology, (C) funds borrowed from other lenders, or (D) any combination of sources under clauses (A) through (C). Under the Credit Agreement, BioTime will prepay, and the credit line will be reduced by, any funds received prior to the maturity date from those sources discussed above. In consideration for making the line of credit available, BioTime issued to the investors a total of 99,999 common shares. The line of credit is collateralized by a security interest in BioTime's right to receive royalty and other payments under the license agreement with Hospira. The market value of BioTime common shares was $0.38 per common share on April 12, 2006, valuing the shares at $38,000. As of June 30, 2007, we had drawn $300,000 against this line of credit.

We have no contractual obligations as of June 30, 2007, with the exception of a fixed, non-cancelable operating lease on our office and laboratory facilities in Emeryville, California. Under this lease, we are committed to make payments of $11,127 per month, increasing 3% annually, plus our pro rata share of operating costs for the building and office complex, through May 31, 2010.

Our net cash used in operating activities during the six months ended June 30, 2007 was $731,996, compared to $834,464 used during the six months ended June 30, 2006. Our net cash provided by financing activities for the six months ended June 30, 2007 was $300,000 worth of borrowings on a line of credit, compared to $126 provided by an exercise of warrants during the six months ended June 30, 2006.
