# NOTES TO CONSOLIDATED
FINANCIAL STATEMENTS (UNAUDITED)

# Note 1. Basis of
Presentation

PURE Bioscience (sometimes referred
to herein as the Company or we) was incorporated in the state of
California on August 24, 1992. The accompanying unaudited financial statements include the
consolidated accounts of PURE Bioscience and its subsidiaries. All inter-company balances
and transactions have been eliminated.

The financial statements included
herein have been prepared by PURE Bioscience without audit, in accordance with the
instructions to Securities and Exchange Commission (SEC) Form 10-Q and Article
10 of Regulation S-X. Certain information and footnote disclosures normally included in
the financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted as allowed by such rules and regulations,
however we believe that the accompanying unaudited financial statements contain all
adjustments (including normal recurring adjustments) necessary to present fairly the
financial condition, results of operations and cash flows for the periods presented. These
unaudited consolidated financial statements presented herein should be read in conjunction
with our audited financial statements for the period ended July 31, 2008, and their
accompanying notes, as filed with the Securities and Exchange Commission in our 10-K on
October 14, 2008.

The preparation of the consolidated
financial statements requires management to make estimates and assumptions that affect the
amounts reported in the statements and accompanying notes, and actual results could differ
materially from those estimates. The results of operations for the three and six months
ended January 31, 2009 are not necessarily indicative of the results of operations for the
full year, or any future periods.

# Note 2. Nature of
Business and Summary of Significant Accounting Policies

Concentration
of Credit Risk

As of January 31, 2009 and July 31,
2008, all cash deposits and short-term investments were invested in either U.S. FDIC
insured bank accounts; institutional money market mutual funds investing in A-1 (S&P)
or Prime-1 (Moodys); U.S. Treasury Securities, or United States Government
obligations issued by or backed by a federal agency of the United States Government.

At January 31, 2009, $404,540 of our
cash and cash equivalents were maintained at two separate major financial institutions in
the United States in accounts that are insured by the Federal Deposit Insurance
Corporation (FDIC) up to $100,000. Effective October 3, 2008, the Emergency
Economic Stabilization Act of 2008 raised the FDIC deposit coverage limits to $250,000 per
owner from $100,000 per owner. The enhanced limits are currently available through
December 31, 2009.

Also at January 31, 2009, $114,820 of
our cash and cash equivalents were held in accounts maintained at two separate major
financial institutions in the United States that are provided with up to $500,000 in
protection by the Securities Investor Protection Corporation (SIPC) should
such a firm close due to bankruptcy or other financial difficulties and customer assets
are missing.

Our short-term investments of
$3,548,012 at January 31, 2009 were all invested in U.S. Treasury Bills with remaining
maturities of less than 360 days, and were held at a major financial institution in the
United States. Assets held within this brokerage account are provided with up to $500,000
in protection by the SIPC.

We have not experienced any losses in
our cash, cash equivalents and short-term investments and believe we are not exposed to
any significant credit risk. At times, deposits held may exceed the amount of insurance
provided by the FDIC or SIPC. Generally, these deposits may be redeemed upon demand and,
therefore, are believed to bear low risk.

Other financial instruments that
potentially subject us to concentrations of credit risk consist of accounts receivable. We
extend credit to our customers based on credit evaluations and past payment performance,
but do not obtain collateral to secure our accounts receivable.

Revenue
Recognition

During the periods presented herein
our product revenue was derived from the sale of silver dihydrogen citrate
(SDC) concentrate and the sale of finished packaged products containing SDC.
We recognize revenue from sales of these products under the provisions of Staff Accounting
Bulletin No. 104, Revenue Recognition, which is generally when we ship the products
free on board from either our facility or from third party packagers, we have transferred
title to the goods, and we have eliminated our risk of loss.

Any amounts received prior to
satisfying our revenue recognition criteria are recorded as deferred revenue in the
accompanying consolidated balance sheets. See Note 3 for further information regarding our
licensing revenues and amounts previously recorded as deferred revenue in the consolidated
balance sheets.

Cost
of Goods Sold

Cost of goods sold for product sales
includes direct and indirect costs to manufacture products, including materials consumed,
manufacturing overheads, shipping costs, salaries, benefits and related expenses of
operations. Cost of goods sold related to licensing revenues recorded in the three and six
month period ended January 31, 2009 were zero, as we did not incur any costs directly
related to our commitments under the agreement to allow a third party a limited time
period to exclusively evaluate our SDC technology.

Intangible
Assets / Long-Lived Assets

Our intangible assets primarily
consist of the worldwide patent portfolio of our silver ion technologies. Outside legal
costs and filing fees related to obtaining patents are capitalized as incurred. The total
amounts capitalized for pending patents were $20,021 and $39,622 in the three month
periods ended January 31, 2009 and 2008, respectively, and $39,684 and $72,495 in the six
month periods ended January 31, 2009 and 2008, respectively. Patents are stated net of
accumulated amortization of $1,165,757 and $1,080,265 at January 31, 2009 and July 31,
2008, respectively. The cumulative cost of acquiring patents is amortized on a
straight-line basis over the estimated remaining useful lives of the patents, generally
between 17 and 20 years from the date of issuance. At January 31, 2009, the weighted
average remaining amortization period for all patents was approximately 11.3 years.
Amortization expense for the three month periods ended January 31, 2009 and 2008 was
$42,877 and $44,048, respectively, and for the six month periods ended January 31, 2009
and 2008 was $85,491 and $87,445, respectively.

Accounting
for Stock-Based Compensation

In December 2004, the Financial
Accounting Standards Board (FASB) revised SFAS 123(R), Share-Based
Payment, which establishes accounting for share-based awards exchanged for employee
and Director services and requires us to expense the estimated fair value of these awards
over the applicable service period. Under SFAS No. 123(R), share-based compensation cost
is measured at the grant date based on the estimated fair value of the award, and is
recognized as expense over the applicable service period. We do not have, and have not had
during the six month periods ended January 31, 2009 or 2008, any stock option awards with
market or performance conditions.

Stock
Options to Non-Employees

Charges for stock options granted to
non-employees have been determined in accordance with SFAS No. 123(R) and EITF No. 96-18,
Accounting for Equity Instruments that are Issued to Other Than Employees for
Acquiring, or in Conjunction with Selling, Goods or Services, whereby we use the
estimated fair value of the stock options issued, based on the Black-Scholes Option
Pricing Model. During the three month period ended January 31, 2009 we recorded $702 in
research and development expense; and during the three month period ended January 31, 2008
we recorded $75,205 in selling expense, and $3,253 in research and development expense.
During the six month period ended January 31, 2009 we recorded $5,681 in research and
development expense; and during the six month period ended January 31, 2008 we recorded
$75,205 in selling expense, and $13,011 in research and development expense.

Cash,
Cash Equivalents and Short-term Investments

We consider all liquid investments
with maturities of ninety days or less when purchased to be cash equivalents. Our
short-term investments have maturities of greater than ninety days from the date of
purchase. We classify securities as available-for-sale in accordance with SFAS
115, Accounting for Certain Investments in Debt and Equity Securities, and carry
these investments at fair value with any unrealized gains and losses reported as a
component of shareholders equity on the consolidated balance sheets and in the
statements of shareholders equity. All of our short-term investments as of July 31,
2008 and January 31, 2009 are carried at fair value, based upon market prices quoted on
the last day of the fiscal period, and are considered available for sale. We use the
specific identification method to determine the cost of debt securities sold, and include
gross realized gains and losses in investment income. Realized gains recorded for the
three month periods ended January 31, 2009 and 2008 were $3,086 and $17,188, respectively,
and for the six month periods ended January 31, 2009 and 2008 were $38,788 and $23,090,
respectively. All interest and dividends received from short-term investments are included
in interest income.

Comprehensive
Income

SFAS 130, Reporting Comprehensive
Income, requires us to display comprehensive income or loss and its components as part
of our consolidated financial statements. Our comprehensive loss includes our net loss and
certain changes in equity that are excluded from our net loss, including unrealized
holding gains and losses on available-for-sale securities. SFAS 130 requires such changes
in shareholders equity to be included in accumulated other comprehensive income or
loss. For the three month periods ended January 31, 2009 and 2008, our comprehensive loss
was $2,205,923 and $1,483,876, respectively. During the three month periods ended January
31, 2009 and 2008, unrealized gains on available for sale securities increased by of
$13,826 and $69,831, respectively. Realized gains on the sale of available for sale
securities, which are included in our net loss for the three month periods ended January
31, 2009 and 2008, were $3,086 and $17,188, respectively. For the six month periods ended
January 31, 2009 and 2008, our comprehensive loss was $3,825,721 and $2,490,222,
respectively. During the six month period ended January 31, 2009, unrealized gains on
available for sale securities declined by $655, and in the six month period ended January
31, 2008, unrealized gains on available for sale securities increased by $72,189. Realized
gains on the sale of available for sale securities, which are included in our net loss for
the six month periods ended January 31, 2009 and 2008, were $38,788 and 23,090,
respectively.

Net
Loss Per Common Share

In accordance with FASB Statement No.
128, Earnings Per Share (SFAS 128), we compute basic loss per share by
dividing the applicable net loss by the weighted average number of common shares
outstanding during the respective period. Diluted per share amounts assume the conversion,
exercise or issuance of all potential common stock equivalents, including stock options
and warrants, unless the effect is to reduce a loss or increase the income per common
share from continuing operations. As we incurred losses in three and six month periods
ended January 31, 2009 and 2008, we did not include common stock equivalent shares in the
computation of net loss per share as the effect would have been anti-dilutive. Therefore,
both the basic and diluted loss per common share for the three and six month periods ended
January 31, 2009 and 2008 are based on the weighted average number of shares of our common
stock outstanding during the periods.

Recent
Accounting Pronouncements

In September 2006, the FASB issued
Statement of Financial Accounting Standards (SFAS) No. 157, Fair Value
Measurements, which provides a single definition of fair value, a framework for
measuring fair value, and expanded disclosures concerning fair value. Previously,
different definitions of fair value were contained in various accounting pronouncements
creating inconsistencies in measurement and disclosures. SFAS No. 157 applies under those
previously issued pronouncements that prescribe fair value as the relevant measure of
value, except Statement No. 123R and related interpretations and pronouncements that
require or permit measurement similar to fair value but are not intended to measure fair
value. In February 2008, the Financial Accounting Standards Board (FASB)
issued FASB Staff Position (FSP) No. FAS 157-2, Effective Date of
FASB Statement No. 157, which provides a one year deferral of the effective
date of FAS 157 for non-financial assets and non-financial liabilities to years beginning
after November 15, 2008 (our fiscal year ending July 31, 2010). As a result, we are only
partially adopting SFAS No. 157 as it relates to our financial assets and liabilities
until we are required to apply this pronouncement to our non-financial assets and
liabilities beginning with the fiscal year ending July 31, 2010.

In February 2007, the FASB issued
SFAS No. 159, The Fair Value Option for Financial Assets and Financial
LiabilitiesIncluding an Amendment of FASB Statement No. 115. This standard
permits an entity to choose to measure many financial instruments and certain other items
at fair value. Most of the provisions in SFAS No. 159 are elective, however the amendment
to SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities,
applies to all entities with available-for-sale and trading securities. The fair value
option established by SFAS No. 159 permits all entities to choose to measure eligible
items at fair value at specified election dates. Under SFAS No. 159, we would report
unrealized gains and losses on items for which the fair value option has been elected in
earnings at each subsequent reporting date. The fair value option: (a) may be applied
instrument by instrument, with a few exceptions, such as investments otherwise accounted
for by the equity method; (b) is irrevocable (unless a new election date occurs); and (c)
is applied only to entire instruments and not to portions of instruments. This statement
became effective for us August 1, 2008, however, we did not elect the fair value option
for any of our financial assets or financial liabilities.

In December 2007, the FASB issued
SFAS No. 141 (revised 2007), Business Combinations (SFAS 141R). SFAS
141R replaces SFAS No. 141, Business Combinations and requires an acquirer in a business
combination to recognize the assets acquired, the liabilities assumed, including those
arising from contractual contingencies, any contingent consideration, and any
non-controlling interest in the acquiree at the acquisition date, measured at their fair
values as of that date, with limited exceptions specified in SFAS 141R. SFAS 141R also
requires the acquirer in a business combination achieved in stages (sometimes referred to
as a step acquisition) to recognize the identifiable assets and liabilities, as well as
the non-controlling interest in the acquiree, at the full amounts of their fair values (or
other amounts determined in accordance with SFAS 141R). In addition, SFAS 141Rs
requirement to measure the non-controlling interest in the acquiree at fair value will
result in recognizing the goodwill attributable to the non-controlling interest in
addition to that attributable to the acquirer. SFAS 141R amends SFAS No. 109,
Accounting for Income Taxes, to require the acquirer to recognize changes in the
amount of its deferred tax benefits that are recognizable because of a business
combination either in income from continuing operations in the period of the combination,
or directly in contributed capital, depending on the circumstances. It also amends SFAS
142, Goodwill and Other Intangible Assets, to provide guidance on the impairment
testing of acquired research and development intangible assets and assets that the
acquirer intends not to use. SFAS 141R applies prospectively to business combinations for
which the acquisition date is on or after the beginning of the first annual reporting
period beginning on or after December 15, 2008 (our fiscal year ending July 31, 2010). We
do not currently expect the adoption of the provisions of SFAS 141R to have a material
effect on our financial condition, results of operations or cash flows.

In December 2007, the FASB issued
Statement of Financial Accounting Standards No. 160, Non-controlling Interests in
Consolidated Financial Statements (SFAS 160). SFAS 160 amends Accounting
Research Bulletin 51, Consolidated Financial Statements, to establish accounting and
reporting standards for the non-controlling interest in a subsidiary and for the
deconsolidation of a subsidiary. It also clarifies that a non-controlling interest in a
subsidiary is an ownership interest in the consolidated entity that should be reported as
equity in the consolidated financial statements. SFAS 160 also changes the way the
consolidated income statement is presented by requiring consolidated net income to be
reported at amounts that include the amounts attributable to both the parent and the
non-controlling interest. It also requires disclosure, on the face of the consolidated
statement of income, of the amounts of consolidated net income attributable to the parent
and to the non-controlling interest. SFAS 160 requires that a parent recognize a gain or
loss in net income when a subsidiary is deconsolidated and requires expanded disclosures
in the consolidated financial statements that clearly identify and distinguish between the
interests of the parent owners and the interests of the non-controlling owners of a
subsidiary. SFAS 160 is effective for fiscal periods, and interim periods within those
fiscal years, beginning on or after December 15, 2008 (our fiscal year ending July 31,
2010). We do not currently expect the adoption of the provisions of SFAS No. 160 to have a
material effect on our financial condition, results of operations or cash flows.

In April 2008, the FASB issued FSP
No. FAS 142-3, Determination of the Useful Life of Intangible Assets. FSP No.
FAS 142-3 amends the factors that should be considered in developing renewal or extension
assumptions used to determine the useful life of a recognized intangible asset under SFAS
No. 142, Goodwill and Other Intangible Assets. The intent of the position is
to improve the consistency between the useful life of a recognized intangible asset under
SFAS No. 142 and the period of expected cash flows used to measure the fair value of the
asset under SFAS No. 141R, and other U.S. generally accepted accounting principles. The
provisions of FSP No. FAS 142-3 are effective for fiscal years beginning after December
15, 2008 (our fiscal year ending July 31, 2010). We are currently evaluating the impact,
if any, that the adoption of FSP No. FAS 142-3 could have on our consolidated financial
statements or results of operations.

# Note 3. Licensing Revenue

During the three month period ended
July 31, 2008 we recorded deferred revenue on receipt of a non-refundable fee of $250,000
which we received subject to an agreement whereby we allowed a third party a limited time
period to exclusively evaluate our SDC technology for use within specified indications and
for certain products. On termination of the agreement on January 31, 2009, we recognized
the $250,000 as licensing revenue in the consolidated statements of operations for the
three month period ended January 31, 2009.

# Note 4. Accounts
Receivable

Trade accounts receivable are
recorded net of allowances for doubtful accounts. Estimates for allowances for doubtful
accounts are determined based on payment history and individual customer circumstances.
The allowance for doubtful accounts was $781,600 and zero at January 31, 2009 and July 31,
2008, respectively. The allowance for doubtful accounts at January 31, 2009 is made up of
amounts billed during prior periods to two international distributors. During the year
ended July 31, 2008 we granted non-exclusive distribution and blending rights to a new
distributor for the sale of SDC-based products in Colombia. In addition, we granted
non-exclusive distribution and blending rights to a second distributor, which is
affiliated with the first distributor, for the sale of SDC-based products in Argentina,
Venezuela, Panama and Costa Rica. During the three month period ended January 31, 2009 we
determined these accounts to be delinquent. We therefore established a full reserve and
recorded $781,600 as bad debt expense, within general and administrative expense, in the
consolidated statements of operations for the three month period ended January 31, 2009.
Subsequent to July 31, 2008 we have not sold any products to either of the two referenced
distributors.

Management currently considers all
other accounts receivable to be fully collectible.

# Note 5. Fair Value

Effective August 1, 2008, we
adopted Statement of Financial Accounting Standards (SFAS) No. 157, Fair
Value Measurements (SFAS 157). In February 2008, the FASB issued
FASB Staff Position (FSP) No. SFAS 157-2, Effective Date of FASB
Statement No. 157, which provides a one year deferral of the effective date of
SFAS 157 for non-financial assets and non-financial liabilities, except those that are
recognized or disclosed in the financial statements at fair value at least annually. As a
result, we only partially adopted SFAS 157 as it relates to our financial assets and
liabilities until we are required to apply this pronouncement to our non-financial assets
and liabilities beginning with fiscal year 2010. The adoption of SFAS 157 did not have a
material impact on our consolidated results of operations or financial condition.

In October 2008, the FASB issued
FSP No. SFAS 157-3 Determining the Fair Value of a Financial Asset When the
Market for that Asset is Not Active (FSP SFAS 157-3). FSP SFAS 157-3
clarifies the application of SFAS No. 157, in a market that is not active and
provides an example to illustrate key considerations in determining the fair value of a
financial asset when the market for that financial asset is not active. FSP SFAS 157-3 is
effective upon issuance, including prior periods for which financial statements have not
been issued. The adoption of FSP SFAS 157-3 had no impact on our consolidated results of
operations, financial position or cash flows.

SFAS 157 defines fair value,
establishes a framework for measuring fair value under U.S. GAAP and enhances disclosures
about fair value measurements. Fair value is defined under SFAS 157 as the exchange price
that would be received for an asset or paid to transfer a liability (an exit price) in the
principal or most advantageous market for the asset or liability in an orderly transaction
between market participants on the measurement date. Valuation techniques used to measure
fair value under SFAS 157 must maximize the use of observable inputs and minimize the use
of unobservable inputs. SFAS 157 describes a fair value hierarchy based on three levels of
inputs, of which the first two are considered observable and the last unobservable, that
may be used to measure fair value which are the following:

| |  | Level 1 | Quoted prices in active markets for identical assets or liabilities.
| | - | ------- | --------------------------------------------------------------------

| |  | Level 2 | Inputs other than Level 1 that are observable, either directly or indirectly, such
 as quoted prices for similar assets or liabilities; quoted prices in markets that are
 not active; or other inputs that are observable or can be corroborated by observable
 market data for substantially the full term of the assets or liabilities.
| | - | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | Level 3 | Unobservable inputs that are supported by little or no market activity and that are
significant to the fair value of the assets or liabilities.
| | - | ------- | -----------------------------------------------------------------------------------------------------------------------------------------------

The following table represents our
fair value hierarchy for our financial assets (cash, cash equivalents and short-term
investments) measured at fair value on a recurring basis as of January 31, 2009:

|                              | Level 1 |  | Level 2 |           | Level 3 |   | Total |

# Note 6. Other Equity and
Common Stock Transactions

We paid no cash dividends during any
of the periods presented, and have never paid cash dividends.

In August 2008, we received an
aggregate of $150,000 from the exercise of non-employee options to purchase 50,000 shares
of our common stock at an exercise price of $3.00, and received $15,079 from the exercise
of options to purchase 28,450 shares of our common stock by two officers, at an average
exercise price of $0.53.

In September 2008, we entered into a
one year consulting agreement with an independent third party for intellectual property
legal services, the compensation being a fee of $11,000 per month and a two-year bi-annual
vesting option to purchase 25,000 shares of our common stock. The options, which have an
exercise price of $4.41, were valued at $59,745 using the Black-Scholes Option Pricing
Model, assuming no dividend yield, volatility of 103.18% and a risk free interest rate of
2.00%. During the three month period ended October 31, 2008 we expensed $4,979 of the
options fair value to research and development. The options will be revalued quarterly
until fully vested with any change to fair value expensed.

In October 2008, we issued 10,000
shares in exchange for consulting services, valued at $24,600 based on the market price of
$2.46 per share. In addition, there was a net exercise from one of our directors on
165,000 options that resulted in the issuance of 133,430 shares of our common stock. As
these shares were net exercised, as permitted under the respective option agreements, we
did not receive any cash. Furthermore, during the three months ended October 31, 2008 we
recorded $57,412 of employee stock option expense.

In December 2008, we received
$631,600 from the exercise of options to purchase 339,800 shares of our common stock by
one of our directors, at an average exercise price of $1.86. In the same month, there were
net exercises by two of our officers of 444,531 options that resulted in the issuance of
371,583 shares of our common stock. As these shares were net exercised, as permitted under
the respective option agreements, we did not receive any cash.

In January 2009, we received $79,500
from a director for the exercise of options to purchase 150,000 shares of our common stock
at an exercise price of $0.53; and received $18,000 from the same director for the
exercise of common stock warrants to purchase 36,000 shares of our common stock at an
exercise price of $0.50. Furthermore, we issued 10,000 shares in exchange for consulting
services, valued at $34,000, and recorded $64,032 of employee stock option expense.

At January 31, 2009, we had
outstanding warrants to purchase 844,351 shares of our common stock with exercise prices
ranging from $2.56 to $8.60. These warrants expire at various times between March 2009 and
October 2012.

# Note 7. Stock-Based
Compensation

We have, or have had during the
fiscal years presented herein, the following equity incentive plans (the
Plans) pursuant to which we have granted options to acquire our common stock:
the 1998 Directors and Officers Stock Option Plan; the 2001 Directors and Officers Stock
Option Plan: the 2001 ETIH2O Stock Option Plan; the 2001 Consultants and Advisors Stock
Option Plan; the 2002 Non-Qualified Stock Option Plan; the 2002 Employee Incentive Stock
Option Plan; the 2004 Consultants and Advisors Stock Option Plan; and the 2007 Equity
Incentive Plan. The Plans are administered by the Compensation Committee of the Board of
Directors (the Compensation Committee). The exercise price for stock options,
or the value of other incentive grants granted under the Plans, are set by the
Compensation Committee but may not be for less than the fair market value of the shares on
the date the award is granted. The period in which options can be exercised is set by the
Compensation Committee but is not to exceed five years from the date of grant.

On August 1, 2006, we adopted the
provisions of SFAS No. 123 (revised 2004), Share-Based Payment (SFAS123(R)),
requiring us to recognize expense related to the fair value of share-based compensation
awards to employees and directors. We elected to use the modified-prospective-transition
method as permitted by SFAS 123R and therefore have not restated our financial results for
prior fiscal years. We recognize compensation expense for stock option awards on a
straight-line basis over the applicable service period of the award. The service period is
generally the vesting period, with the exception of options granted subject to a
consulting agreement, whereby the option vesting period and the service period defined
pursuant to the terms of the consulting agreement may be different. Share-based
compensation expense for awards granted subsequent to July 31, 2006 is based on the grant
date fair value estimated in accordance with the provisions of SFAS 123R, using the
Black-Scholes Option Pricing Model. The following methodology and assumptions were used to
calculate share based compensation for the six month periods ended January 31, 2009 and
2008:

|                               | For the six month periods ended January 31, | 
|------------------------------ | ------------------------------------------- | 
|
|Expected price volatility      |                                             | 
|Risk-free interest rate        |                                             | 
|Expected rate of forfeiture    |                                             | 
|Expected dividend yield        |                                             | 
|Weighted average expected term |                                             |

Expected price volatility is the
measure by which our stock price is expected to fluctuate during the expected term of an
option. Expected volatility is derived from the historical daily change in the market
price of our common stock, as we believe that historical volatility is the best indicator
of future volatility. For stock options granted subsequent to July 31, 2006, we have
excluded the period prior to November 1, 2005 from our historical price volatility, as
during this period our market price reflected significant uncertainty associated with both
our arbitration proceedings against Falken Industries and our ability to close the sale of
the assets of the Water Treatment Division. We believe that the volatility of the market
price of our common stock during periods prior to November 1, 2005 is not reflective of
future expected volatility.

Following the guidance of Staff
Accounting Bulletin No. 107 (SAB 107), we have been following the
Simplified Method to determine the expected term of Plain Vanilla
options issued to employees and directors. All of our outstanding options granted to
employees and directors are Plain Vanilla options. Under the Simplified Method, the
expected term is presumed to be the mid-point between the vesting date and the end of the
contractual term. In SAB 107, the Staff stated that it would not expect a company to use
the Simplified Method for share option grants after December 31, 2007, however on December
21, 2007, the SEC published Staff Accounting Bulletin No. 110 (SAB 110), which
expressed the views of the Staff regarding the continued use of a Simplified Method in
certain circumstances where a company is unable to rely on historical data. We are unable
to rely on our historical exercise data as there have been only a limited number of option
exercises in recent periods; there have been a limited number of plan participants which
is expected to grow; our common stock was traded until April 2008 on the illiquid Bulletin
Board but our common stock is now listed on the NASDAQ Capital Market; we have had over
recent years significant trading blackout periods for employees and directors; there has
been minimal employee and director turnover; we have recently changed the terms of
employee stock option grants to reduce the term of such grants; there are no comparable
companies in terms of size, location and industry (particularly as we are developing a
platform technology and operate in multiple industries); and we have had significant
structural changes in our business including the sale of the Water Treatment Division and
abandonment of our Triglycylboride technology, and expect to continue to change in the
foreseeable future. We are therefore, under the guidance of SAB 110, continuing to use the
Simplified Method to determine the expected term of options issued to employees and
directors, but will continually evaluate our historical data as a basis for determining
the expected terms of such options.

Our estimation of the expected term
for stock options granted to parties other than employees or directors is the contractual
term of the option award.

For the purposes of estimating the
fair value of stock option awards, the risk-free interest rate used in the Black-Scholes
calculation is based on the prevailing U.S. Treasury yield as determined by the U.S.
Federal Reserve. We have never paid any cash dividends on our common stock and do not
anticipate paying cash dividends on our common stock in the foreseeable future.

Stock-based compensation expense
recognized in the consolidated statements of operations is based on awards ultimately
expected to vest, reduced for estimated forfeitures. SFAS 123R requires forfeitures to be
estimated at the time of grant, and revised, if necessary, in subsequent periods if actual
forfeitures differ from those estimates. Historically, we have not had significant
forfeitures of unvested stock options granted to employees and directors. A significant
number of our stock option grants are fully vested at issuance or have short vesting
provisions. Therefore, we have estimated the forfeiture rate of our outstanding stock
options as zero, but will continually evaluate our historical data as a basis for
determining expected forfeitures.

operating decisions and assessing performance. SFAS 131 requires that we apply standards
based on a management approach, and requires segmentation based upon our internal
organization and disclosure of revenue and operating income based upon internal accounting
methods. In determining operating segments, we have reviewed the current management
structure reporting to the chief operating decision-maker (CODM) and analyzed
the reporting the CODM receives to allocate resources and measure performance.

We have determined that based upon
the end use of our products, the value added contributions made by us, the regulatory
requirements, the customers and partners, and the strategy required to successfully market
finished products, we are operating in a single segment.

Our customers are strategic partners
who are developing markets for products that include our SDC technology, and distributors
who sell products containing SDC under multiple regulatory approvals. During the three
month period ended January 31, 2009, 90% of product sales were made to five strategic
partners that are also developing markets for our products. During the six month period
ended January 31, 2009, 71% of product sales were made to three strategic partners that
are also developing markets for our products. 100% of product sales for the six month
period ended January 31, 2009 were made to U.S. domestic customers.

During the three month period ended
January 31, 2009, 100% of our product sales were of bulk Axen30 or finished packaged
products containing Axen 30, our ready to use product. None of our product sales for the
period were  of bulk SDC concentrate. During the same period of the prior year, 71% of
our product sales were of bulk SDC concentrate and 29% of our product sales were of bulk
Axen30 or finished packaged products containing Axen 30.

During the six month period ended January 31, 2009, 10% of our product sales were of bulk SDC concentrate and 90% of our product
sales were of bulk Axen30 or finished packaged products containing Axen 30. During the same period of the prior year, 67% of our
product sales were of bulk SDC concentrate and 33% of our product sales were of bulk Axen30 or finished packaged products
containing Axen 30.

All of our tangible assets are
located in the United States.

# OVERVIEW

PURE Bioscience (sometimes referred
to herein as the Company or we) was incorporated in the state of
California on August 24, 1992. We began as a provider of pharmaceutical water purification
products. We now focus on markets that we believe have broader potential by developing
new, proprietary bioscience products based upon our patented silver ion antimicrobial
technologies. We are developing technology-based bioscience products, including our silver
dihydrogen citrate-based antimicrobials, which we believe have the potential to provide
best in class, non-toxic solutions to numerous global health challenges and represent
innovative advances in diverse markets. We believe that our technologies are in a position
to contribute significantly to todays global trend toward industrial and consumer
use of green products, while providing competitive advantages in efficacy and
safety.

Bioscience
Technologies

Our flagship bioscience technology is
an aqueous disinfectant, silver dihydrogen citrate (SDC). A patented new
molecular entity, SDC is an electrolytically generated source of stabilized ionic silver
that can serve as the basis for a broad range of products in diverse markets. SDC liquid
is colorless, odorless, tasteless, non-caustic and formulates well with other compounds.
As a platform technology, our SDC-based antimicrobial is distinguished from competitors in
the marketplace because of its superior efficacy combined with reduced toxicity. We are
producing and plan to expand the production of pre-formulated, ready-to-use products for
private label distribution, as well as varying strengths of SDC concentrate as an additive
or raw material for inclusion in other companies products, including as an active
pharmaceutical ingredient. In addition to SDC, we have obtained patent protection for
ionic silver-based molecular entities utilizing 14 organic acids other than citric acid.

We also own certain rights to a
patent-pending pesticide technology, Triglycylboride which, like SDC, provides
effective results without human toxicity and is an alternative to traditional poisons.
Triglycylboride has been formulated into our Environmental Protection Agency
(EPA) registered RoachX® and AntX products, though these products
are not currently being actively marketed or developed.

Sources
of Revenue

Our principal sources of revenue are
comprised of sales of SDC concentrate as well as both bulk and individually bottled
SDC-based hard surface disinfectant. SDC concentrate is sold to distributors that either
resell the concentrate as an active ingredient or preservative in other companies
products, or blend the product into hard surface disinfectant products for sale to retail,
commercial and institutional customers. SDC-based hard surface disinfectant is sold in
bulk and as individually bottled products to distributors that in turn sell the product to
retail, commercial and institutional customers. In addition to sales of SDC concentrate
and finished goods, we anticipate generating additional revenues from licensing and
royalty arrangements in future periods.

Because the development of our SDC
technology is at an early stage of development and commercialization, it is difficult to
predict our revenues. Our historical revenues have fluctuated from period to period based
on factors that include, but are not limited to, the timing of approvals of our
applications and our partners applications to regulatory agencies in both the United
States and overseas; the timing of product launches by both our strategic partners and, in
some cases, their customers and partners; the timing of our entry into new strategic
agreements, and the quantities of our products required by our partners to effect new
research programs and product launches.

For example, for the six month period
ended January 31, 2009 we reported revenues from product sales of $145,400, compared with
revenue from product sales in the three month period ended July 31, 2008 of $823,300.
During the year ended July 31, 2008 we granted non-exclusive distribution and blending
rights to a new partner for the sale of SDC-based products in Colombia. In addition, we
granted non-exclusive distribution and blending rights to a second partner, which is
affiliated with the first partner, for the sale of SDC-based products in Argentina,
Venezuela, Panama and Costa Rica. Our sales of SDC concentrate to these partners in the
three month period ended July 31, 2008 were $757,200. We believe that the SDC concentrate
was ordered by these partners to provide sufficient material to blend into end-use
products for sale, on the receipt of the necessary regulatory approvals in each of these
countries.

In future periods, we expect our
revenues to continue to fluctuate. In some cases, we will not be aware of the launch of
products containing SDC until they are available to end-users, such as under our agreement
with Ciba. In February 2009 the first name brand personal care products containing SDC as
the active ingredient were launched in Europe by a customer of Ciba. We were not able to
anticipate this launch due to the wishes of Cibas customer to maintain a competitive
position in their respective industry, although we would have sold to Ciba the SDC used as
an active ingredient by Cibas customer in prior periods.

Cost
of Revenues and Operating Expenses

Costs of Revenue.
  Costs of product revenue includes materials consumed, manufacturing overheads,
shipping costs, salaries, benefits and related expenses of operations. Gross profit on
product sales represents net revenue less the costs of revenue. Gross profit percentage is
highly dependent on pricing, contractual agreements, and overhead allocations. We do not
believe that historical gross profit margins on product sales are a reliable indicator of
future gross profit margins.

During the three month period January
31, 2009 we recorded $250,000 of licensing revenue on the expiration of an agreement
whereby we allowed a third party a limited time period to exclusively evaluate our SDC
technology. Cost of goods sold related to this revenue was zero, as we did not incur any
costs directly related to our commitments under the agreement.

Selling and Marketing.  Selling and marketing expenses consist primarily of salaries, commissions
and related expenses for personnel engaged in marketing, sales, public relations and
advertising, along with promotional and trade show costs and travel expenses. Sales and
marketing expenses also include share-based compensation allocable to personnel performing
services related to sales and marketing.

General and Administrative.  General and administrative expenses include salaries and related expenses
for personnel engaged in finance, human resources, insurance, information technology,
administrative activities and legal and accounting fees. General and administrative
expenses also include share-based compensation allocable to personnel performing general
and administrative services.

Research and
Development.   Research and development costs include in-house costs, patent
amortization, outside legal costs for maintaining issued patents, and product registration
expenditures. We do not currently expect our research and development expense to grow
significantly in future periods, however if opportunities arise, particularly in the
development and testing of new formulations, we will evaluate the need for additional
research expenditures based on potential market sizes and our estimation of the likelihood
of our technology achieving successful results.

# CRITICAL ACCOUNTING
POLICIES

Accounting
for Long-Lived Assets / Intangible Assets

We assess the impairment of
long-lived assets, consisting of property, plant, equipment and finite-lived intangible
assets, whenever events or circumstances indicate that the carrying value may not be
recoverable. Examples of such events or circumstances include:

| |  | An
assets ability to continue to generate income from operations and positive cash
flow in future periods;
| | - | -----------------------------------------------------------------------------------------------------------

| |  | Loss
of legal ownership or title to an asset;
| | - | ---------------------------------------------

| |  | Significant
changes in our strategic business objectives and utilization of the asset(s); and
| | - | ---------------------------------------------------------------------------------------------

| |  | The
impact of significant negative industry or economic trends.
| | - | ---------------------------------------------------------------

Recoverability of assets to be held
and used in operations is measured by a comparison of the carrying amount of an asset to
the future net cash flows expected to be generated by the assets. The factors used to
evaluate the future net cash flows, while reasonable, requires a high degree of judgment
and the results could vary if the actual results are materially different than the
forecasts. In addition, we base useful lives and amortization or depreciation expense on
our subjective estimate of the period that the assets will generate revenue or otherwise
be used by us. If such assets are considered to be impaired, the impairment to be
recognized is measured by the amount by which the carrying amount of the assets exceeds
the fair value of the assets. Assets to be disposed of are reported at the lower of the
carrying amount or fair value less selling costs.

16

---



We also periodically review the lives
assigned to our intangible assets to ensure that our initial estimates do not exceed any
revised estimated periods from which we expect to realize cash flows from the
technologies. If a change were to occur in any of the above-mentioned factors or
estimates, the likelihood of a material change in our reported results would increase.

Accounting
for Stock-Based Compensation

We adopted the fair value provisions
of SFAS 123(R) on August 1, 2006. Stock-based compensation expense for all stock-based
compensation awards granted after August 1, 2006 is based on the grant date fair value
estimated in accordance with the provisions of SFAS 123(R). Specifically, we estimate the
weighted-average fair value of options granted using the Black-Scholes Option Pricing
Model based on evaluation assumptions regarding expected volatility, dividend yield,
risk-free interest rates, the expected term of the option and the expected forfeiture
rate. Each of these assumptions, while reasonable, requires a certain degree of judgment
and the fair value estimates could vary if the actual results are materially different
than those initially applied. Prior to the adoption of SFAS 123(R), we were not required
to record compensation cost in the consolidated financial statements for stock options
issued to employees or directors.

RESULTS OF OPERATIONS FOR THE
THREE MONTHS ENDED JANUARY 31, 2009 VS. THREE MONTHS ENDED JANUARY 31, 2008

# Revenue and Gross Margin

For the three month period ended January
31, 2009 (the Second Quarter), product revenues of $34,800 declined by
$117,700, or 77%, compared with the three months ended January 31, 2008. Product revenues
for each of the quarters presented were derived from sales of finished products to our
non-exclusive distributors, and product provided to our partners for evaluation and
testing purposes. 90% of product sales for the Second Quarter were made to five strategic
partners that are pursuing regulatory approvals and developing markets for our products.
100% of product sales for the Second Quarter were to U.S. domestic customers.

Gross profit on product sales for the Second Quarter was $23,900, compared with $101,900 in the same
period of the prior fiscal year. The gross margin percentage increased from 67% in the prior fiscal year
to 69% in the current period. The improvement is primarily due to efficiencies gained in our in-house
manufacturing and bottling operations. Such efficiencies were partially offset by an increased
proportion of lower margin products sold in the most recent period. During the three month period ended
January 31, 2009, 100% of our product sales were of bulk Axen30 or finished packaged products containing
Axen 30, our ready to use product. None of our product sales for the period were of bulk SDC
concentrate. During the same period of the prior year, 71% of our product sales were of bulk SDC
concentrate and 29% of our product sales were of bulk Axen30 or finished packaged products containing
Axen 30. We generally sell our SDC bulk concentrate at higher margins than our ready to use products.

During the three month period ended
July 31, 2008 we recorded deferred revenue on receipt of a non-refundable fee of $250,000,
which we received subject to an agreement whereby we allowed a third party a limited time
period to exclusively evaluate our SDC technology for use within specified indications and
for certain products. On termination of the agreement on January 31, 2009, we recognized
the $250,000 as licensing revenue in the consolidated statements of operations for the
Second Quarter. Cost of goods sold related to this revenue was zero, as we did not incur
any costs directly related to our commitments under the agreement.

# Operating Costs

Operating costs increased by
$818,300, from $1,680,000 in the three months ended January 31, 2008, to $2,498,300 in the
Second Quarter. Within these aggregate operating costs, selling expenses declined by
$20,700 to $185,900 in the Second Quarter compared with the same period in the prior
fiscal year. The decrease in selling expenses is primarily due to $91,400 of additional
salary expense in the Second Quarter being more than offset by $115,400 of consulting fees
in the three month period ended January 31, 2008.

General and administrative expenses
increased by $688,300 to $1,858,300 in the Second Quarter, compared with the three months
ended January 31, 2008. Included in general and administrative expense for the Second
Quarter is $781,600 of expense related to an allowance for doubtful accounts. This amount
is made up of amounts billed during prior periods to two international distributors.
During the year ended July 31, 2008 we granted non-exclusive distribution and blending
rights to a new distributor for the sale of SDC-based products in Colombia. In addition,
we granted non-exclusive distribution and blending rights to a second distributor, which
is affiliated with the first distributor, for the sale of SDC-based products in Argentina,
Venezuela, Panama and Costa Rica. During the three month period ended January 31, 2009 we
determined these accounts to be delinquent. We therefore established a full reserve and
recorded $781,600 as bad debt expense, within general and administrative expense, in the
consolidated statements of operations for the three and six month  periods ended
January 31, 2009. Subsequent to July 31, 2008 we have not sold any products to either of
the two referenced distributors. Management currently considers all other accounts
receivable to be fully collectible.

Legal fees charged to general and
administrative expense, primarily related to the development of contracts and protection
of our intellectual property, increased by $64,100 compared to the same period in the
prior fiscal year, while insurance costs increased by $64,700. Other general and
administrative expenditures such as depreciation, board of director fees and other
professional services also increased during the Second Quarter compared with the same
period of the prior fiscal year, however these increases were offset by a decline of
$311,400 in stock option expense charged to general and administrative expense. During the
three months ended January 31, 2008 we issued an option to purchase up to 100,000 shares
of our common stock to a new director, for which $351,000 of expense was recorded in the
period. We recognized employee and director stock option non-cash expense in general and
administrative expenses for the Second Quarter of $64,000, and for the three months ended
January 31, 2008 of $375,800.

17

---



Research and development costs,
including in-house costs, patent amortization, outside legal costs for maintaining
approved patents, and product registration expenditures, increased by $150,700, from
$303,300 in the three months ended January 31, 2008 to $454,000 in the Second Quarter. The
increase in expense is primarily related to increases in payroll, stock option expense,
patent expense and third-party testing. We do not currently expect our research and
development expense to grow significantly in future periods; however, if opportunities
arise, particularly in the development and testing of new formulations, we will evaluate
the need for additional research expenditures based on potential market sizes and our
estimation of the likelihood of our technology achieving successful results.

Our loss from operations before taxes
increased by $646,300 from a loss of $1,578,000 for the three months ended January 31,
2008 to a loss of $2,224,300 for the Second Quarter.

# Other Income

Other income declined by $19,700 in
the Second Quarter compared to the same period of the prior fiscal year, due primarily to
decreased interest income from lower average cash balances and lower interest rates.

# Net Income (Loss)

Our net loss after taxes increased by
$666,000 from a net loss of $1,553,700 for the three months ended January 31, 2008 to a
net loss of $2,219,800 for the Second Quarter.

RESULTS OF OPERATIONS FOR THE SIX
MONTHS ENDED JANUARY 31, 2009 VS. SIX MONTHS ENDED JANUARY 31, 2008

# Revenue and Gross Margin

For the six months ended January 31, 2009,
product revenues of $145,400 declined by $102,300 or 41%, compared with the six months
ended January 31, 2008. Product revenues for each of the six month periods presented was
derived from sales of finished products to our non-exclusive distributors, and product
provided to our partners for evaluation and testing purposes. 71% of product sales for the
six months ended January 31, 2009 were made to three strategic partners that are pursuing
regulatory approvals and developing markets for our products. 100% of product sales for
the six months ended January 31, 2009 were made to U.S. domestic customers.

Gross profit on product sales for the six months ended January 31, 2009 was $74,700, compared with
$165,500 in the same period of the prior fiscal year. The gross margin percentage declined from 67% in
the prior year to 51% in the current period, primarily due to an increased proportion of lower margin
products sold in the most recent period. During the six month period ended January 31, 2009, 10% of our
product sales were of bulk SDC concentrate and 90% of our product sales were of bulk Axen30 or finished
packaged products containing Axen 30, our ready to use product. During the same period of the prior
year, 67% of our product sales were of bulk SDC concentrate and 33% of our product sales were of bulk
Axen30 or finished packaged products containing Axen 30. We generally sell our SDC bulk concentrate at
higher margins than our ready to use products. The decline in overall gross margin caused by the
increased proportion of lower margin products in the most recent period was partially offset by
efficiencies gained in our in-house manufacturing and bottling operations.

During the three month period ended
July 31, 2008 we recorded deferred revenue on receipt of a non-refundable fee of $250,000
which we received subject to an agreement whereby we allowed a third party a limited time
period to exclusively evaluate our SDC technology for use within specified indications and
for certain products. On termination of the agreement on January 31, 2009, we recognized
the $250,000 as licensing revenue in the consolidated statements of operations for the
three and six month periods ended January 31, 2009. Cost of goods sold related to this
revenue was zero, as we did not incur any costs directly related to our commitments under
the agreement.

# Operating Costs

Operating costs increased by 52%,
from $2,764,000 in the six months ended January 31, 2008, to $4,199,000 in the six months
ended January 31, 2009. Within these aggregate operating costs, selling expenses increased
by $42,300, to $337,100 in the current period compared with the same period in the prior
fiscal year. The increase in selling expenses is primarily due to $162,500 of additional
salary expense for business development personnel, partially offset by $127,900 of
consulting fees in the six month period ended January 31, 2008.

General and administrative expenses
increased by $1,243,086 or 66%, to $3,120,800 in the six months ended January 31, 2009,
compared with the six months ended January 31, 2008. Included in general and
administrative expense for the six months ended January 31, 2009 is $781,600 of expense
related to an allowance for doubtful accounts. This amount is made up of amounts billed
during prior periods to two international distributors. During the year ended July 31,
2008 we granted non-exclusive distribution and blending rights to a new distributor for
the sale of SDC-based products in Colombia. In addition, we granted non-exclusive
distribution and blending rights to a second distributor, which is affiliated with the
first distributor, for the sale of SDC-based products in Argentina, Venezuela, Panama and
Costa Rica. During the three month period ended January 31, 2009 we determined these
accounts to be delinquent. We therefore established a full reserve and recorded $781,600
as bad debt expense, within general and administrative expense, in the consolidated
statements of operations for the three and six month  periods ended January 31, 2009.
Subsequent to July 31, 2008 we have not sold any products to either of the two referenced
distributors. Management currently considers all other accounts receivable to be fully
collectible.

18

---



General and administrative payroll
expense increased by $215,000 year over year due to new hires and salary increases, and
accounting and legal fees increased by $269,000. Additionally, insurance, depreciation,
rent, and board of director fees accounted for $213,400 of the increase in general and
administrative expense for the six months ended January 31, 2009 compared with the six
months ended January 31, 2008. These increases were partially offset by a decline of
$279,200 in stock option expense for the six month period ended January 31, 2009 compared
with the same period of the prior fiscal year. We recognized employee and director stock
option non-cash expense in general and administrative expenses for the six months ended
January 31, 2009 of $121,400, and for the six months ended January 31, 2008 of $400,700.

Research and development costs,
including in-house costs, patent amortization, outside legal costs for maintaining
approved patents, and product registration expenditures, increased in the six month period
ended January 31, 2009 by 25% to $741,000, compared with the same period in the prior
fiscal year. The increase in expense is primarily related to increases in payroll and in
third-party testing costs. We do not currently expect our research and development expense
to grow significantly in future periods, however if opportunities arise, particularly in
the development and testing of new formulations, we will evaluate the need for additional
research expenditures based on potential market sizes and our estimation of the likelihood
of our technology achieving successful results.

Our loss from operations before taxes
increased by $1,275,700, from a loss of $2,598,500 for the six months ended January 31,
2008 to a loss of $3,874,100 for the six months ended January 31, 2009.

# Other Income

Other income increased by $13,000 in
the current six month period compared to the same period of the prior fiscal year. Gains
on the sale of U.S. Treasury Bills were partially offset by decreased interest income from
lower average cash balances and lower interest rates.

# Net Income (Loss)

Our net loss after taxes increased by
$1,262,700, from a net loss of $2,562,400 for the six months ended January 31, 2008 to a
net loss of $3,825,100 for the six months ended January 31, 2009.

# LIQUIDITY AND CAPITAL
RESOURCES

From inception through the present,
we have financed our operations primarily through sales of our equity securities, through
lines of credit and the issuance of debentures and in May 2005 by the sale of our Water
Treatment Division. At January 31, 2009, we had cash, cash equivalents and short-term
investments of $4,067,400, a decline of $2,564,900 from July 31, 2008, and no long-term
debt. Cash and cash equivalents at January 31, 2009 were $519,400, a decrease for the six
month period from July 31, 2008 of $1,505,000, while short-term investments decreased over
the same period by $1,059,900, to $3,548,000.

Total current assets at January 31,
2009 were $4,683,400, a decrease of $3,206,200 from July 31, 2008. Cash used in operating
activities for the six months ended January 31, 2009 was $3,352,100, compared with
$2,321,300 for the same six month period of the prior fiscal year. The increase in
operating cash expenditures is primarily a result of increased general and administrative
expenses including payroll, insurance, legal fees and professional services, and research
and development expenses. The value of our raw materials and finished goods inventory grew
by $105,400 over the same period, primarily due to the purchase of raw materials for our
concentrate manufacturing and our bottling processes. In addition, prepaid expenses
increased by $69,000 from July 31, 2008 to January 31, 2009.

During the six months ended January
31, 2009, cash provided by investing activities was $952,900. Of this amount, a net amount
(cash sales less cash purchases) of $1,059,200 was provided by short-term investments. In
addition, during the six months ended January 31, 2009 we invested $39,700 in patents,
however the capitalized value of our patents at January 31, 2009 declined by $45,800 from
July 31, 2008 due to an excess of patent amortization over capitalization. Total property,
plant and equipment at January 31, 2009 of $968,400 declined by $66,400 from July 31,
2008, due to an excess of depreciation over new asset acquisitions. Our purchases of
property, plant and equipment for the six month period ended January 31, 2009 were
$66,600.

Total cash inflows from financing
activities for the six months ended January 31, 2009 were $894,200, all of which was
derived from proceeds from the exercise of stock options and warrants. In August 2008, we
received an aggregate of $150,000 from the exercise of non-employee options to purchase
50,000 shares of our common stock at an exercise price of $3.00, and received $15,100 from
the exercise of options to purchase 28,450 shares of our common stock by two officers, at
an average exercise price of $0.53. In December 2008, we received an aggregate of $631,600
from a director for the exercise of options to purchase 339,800 shares of our common stock
at an average exercise price of $1.86. In January 2009, we received $79,500 from a
director for the exercise of options to purchase 150,000 shares of our common stock at an
exercise price of $0.53; and received $18,000 from the same director for the exercise of
common stock warrants to purchase 36,000 shares of our common stock at an exercise price
of $0.50.

Net accounts receivable declined by
$815,800 from July 31, 2008 to January 31, 2009. During the Second Quarter of the year
ending July 31, 2009 we recorded an allowance for doubtful accounts of $781,600 related to
amounts, billed in prior periods to two international distributors, which we determined
during the quarter to be delinquent.

At January 31, 2009, we had current
liabilities of $405,700, a decrease of $575,800 from July 31, 2008, primarily due to a
decline in accounts payable of $364,100 and a decline of $256,800 in deferred revenue. In
the Second Quarter of 2009, we recognized $250,000 of licensing revenue on the
consolidated statements of operations. This amount had previously been recorded as
deferred revenue on receipt of a non-refundable fee.

We expect to continue to invest in
our manufacturing processes, to improve efficiency and to be able to meet anticipated
demand.  Additionally, during the next twelve months, we anticipate making
significant investments in regulatory applications for new products or additional claims,
in our corporate and business development infrastructure and in programs required for us
to maintain our compliance with securities laws as well as the listing standards of the
NASDAQ Capital Market, among other investments.  We believe, however, that our cash
resources are sufficient to meet our anticipated needs during the next twelve months. Our
assessment is based on historical working capital needs, operating loss trends, and our
current business outlook. However, we may need additional financing and there can be no
assurance that when additional financing is necessary it will be available, or if
available, that such financing can be obtained on satisfactory terms or without undue
dilution to, or an adverse impact on the rights of, our shareholders. If adequate funds
are not available when needed, we may be required to significantly modify our business
model to reduce spending to a sustainable level. Such modification of the business model
could also result in an impairment of assets which cannot be determined at this time.

# OFF BALANCE SHEET
ARRANGEMENTS

We do not have any off balance sheet
arrangements.

# ITEM 3. QUANTITATIVE AND
QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our exposure to interest rate risk at
January 31, 2009 is related to our investment portfolio which consists largely of debt
instruments and other securities of high quality corporate issuers and the U.S. government
and its agencies. From time to time our investments may be exposed to market risk related
to changes in interest rates. Our current investment policy is to maintain an investment
portfolio consisting only of diversified institutional money market mutual funds investing
in A-1 (S&P) or Prime-1 (Moodys); U.S. Treasury Securities, or United States
Government obligations issued by or backed by a federal agency of the United States
Government. We do not enter into investments for trading or speculative purposes, and our
cash is deposited in, and invested through, highly rated financial institutions in the
United States. While our available for sale securities are subject to interest rate risk
and would fall in value if market interest rates increased, we estimate that the fair
value of our investment portfolio would not decline by a material amount in the event of
an increase in market interest rates. We therefore would not expect our operating results
or cash flows to be affected to any significant degree by the effect of a change in market
interest rates on our investments.

We have operated mainly in the United
States, and the majority of our sales since inception have been made in U.S. dollars.
Further, all of our sales to international markets have been to independent parties in
transactions conducted in U.S. dollars. Accordingly, we have not had any material exposure
to foreign currency rate fluctuations.

# ITEM 4. CONTROLS AND
PROCEDURES

We maintain disclosure controls and
procedures that are designed to ensure that information required to be disclosed in our
Exchange Act reports is recorded, processed, summarized and reported within the time
periods specified in the SECs rules and forms, and that such information is
accumulated and communicated to our management, including our Chief Executive Officer and
Chief Financial Officer, who also acts as our Principal Accounting Officer, as
appropriate, to allow timely decisions regarding required disclosure based closely on the
definition of disclosure controls and procedures in Rule 13a-14(c). In
designing and evaluating the disclosure controls and procedures, management recognized
that any controls and procedures, no matter how well designed and operated, can provide
only reasonable assurance of achieving the desired control objectives, and management
necessarily was required to apply its judgment in evaluating the cost-benefit relationship
of possible controls and procedures.

# Evaluation of Disclosure
Controls and Procedures

We have carried out an evaluation
under the supervision and with the participation of our management, including our Chief
Executive Officer and our Chief Financial Officer/Principal Accounting Officer, of the
effectiveness of the design and operation of all of our disclosure controls and
procedures. Based on the foregoing, our Chief Executive Officer and Chief Financial
Officer/Principal Accounting Officer concluded that our disclosure controls and procedures
were effective as of January 31, 2009.

# Changes in Internal
Control Over Financial Reporting

We made no changes in our internal
control over financial reporting during the Second Quarter that have materially affected,
or are reasonably likely to materially affect, our internal control over financial
reporting.

# PART II  OTHER
INFORMATION

# ITEM 1. LEGAL PROCEEDINGS

From time to time, we may become
involved in various lawsuits and legal proceedings which arise in the ordinary course of
business. However, litigation is subject to inherent uncertainties, and an adverse result
in these or other matters may arise from time to time that may harm our business. We are
not currently aware of any such legal proceedings or claims that we believe will have,
individually or in the aggregate, a material adverse effect on our business, financial
condition or operating results.

# ITEM 1A. RISK FACTORS

Except for the historical
information contained herein or incorporated by reference, this quarterly report on Form
10-Q and the information incorporated by reference contains forward-looking statements
that involve risks and uncertainties. These statements include projections about our
accounting and finances, plans and objectives for the future, future operating and
economic performance and other statements regarding future performance. These statements
are not guarantees of future performance or events. Our actual results may differ
materially from those discussed here. Factors that could cause or contribute to
differences in our actual results include those discussed in the following section, as
well as those discussed in Part I, Item 2 entitled Managements Discussion and
Analysis of Financial Condition and Results of Operations and elsewhere throughout
this quarterly report on Form 10-Q and in any other documents incorporated by reference
into this report. You should consider carefully the following risk factors, together with
all of the other information included or incorporated in this quarterly report on Form
10-Q. Each of these risk factors, either alone or taken together, could adversely affect
our business, operating results and financial condition, as well as adversely affect the
value of an investment in our common stock. There may be additional risks that we do not
presently know of or that we currently believe are immaterial which could also impair our
business and financial position. If any of the events described below were to occur, our
financial condition, our ability to access capital resources, our results of operations
and/or our future growth prospects could be materially and adversely affected and the
market price of our common stock could decline. As a result you could lose some or all of
any investment you may have made or may make in our common stock.

We have a history of losses, and
we may not achieve or maintain profitability

We had a loss of $3,825,100 after
taxes for the six month period ended January 31, 2009, a loss of $6,540,300 after taxes
for the fiscal year ended July 31, 2008, and a loss of $4,654,900 after taxes for the
fiscal year ended July 31, 2007. As of January 31, 2009, we had an accumulated deficit of
approximately $35.3 million. We may continue to have losses in the future. If the
penetration into the marketplace of SDC is later than anticipated, revenue growth is
slower than anticipated or operating expenses exceed expectations, it may take an
unforeseen period of time to achieve or sustain profitability and we may never achieve or
sustain profitability. Slower than anticipated revenue growth could force us to reduce
research, testing, development and marketing of our technology and/or force us to reduce
the size and scope of our operations, or cease operations altogether. If we do become
profitable in future periods, we have an employment contract with our Chief Executive
Officer and President which includes a provision for him to be paid an amount equal to 3%
of our net income before taxes, if any. Such payments would reduce our profitability.

We do not yet have significant cash
inflows from product sales or from other sources of revenue to offset our ongoing and
planned investments in corporate infrastructure, research and development projects,
regulatory submissions, business development activities, and sales and marketing, among
other investments. These investments may not be successful. In addition, some of these
investments cannot be postponed and we may be contractually or legally obligated to make
them. In future periods we may need to seek additional capital through the issuance of
debt, common stock, preferred stock, convertible securities or through other means, any
one of which could reduce the value, perhaps substantially, of the common stock we have
issued as of the date of this Report on Form 10-Q. We currently have no long-term debt,
however the issuance of debt, common stock, preferred stock, or convertible securities in
future periods, if any, could lead to the dilution of our existing shareholders. There is
no guarantee that we would be able to obtain capital on terms acceptable to us, or at all.
Insufficient funds could cause us to fail to execute our business plan, fail to take
advantage of future opportunities, or fail to respond to competitive pressures or
unanticipated customer requirements, and further may require us to delay, reduce or
eliminate some or all of our research and product development programs, license to third
parties the right to commercialize products or technologies that we would otherwise
commercialize ourselves, or to reduce or cease operations.

The risks associated with our
business may be more acute during periods of economic slowdown or recession. In addition
to other consequences, these periods may be accompanied by decreased consumer spending
generally, as well as decreased demand for, or additional downward pricing pressure on our
products. Accordingly, any prolonged economic slowdown or a lengthy or severe recession
with respect to either the U.S. or the global economy is likely to have a material adverse
effect on our results of operations, financial condition and business prospects. As a
result, given the current deterioration in U.S. and global economy, as well as the
decreasing purchasing power of consumers and institutions, we expect that our business
will continue to be adversely affected for so long as, and to the extent that, such
adverse economic conditions exist.

If our efforts to achieve and
maintain market acceptance of our core SDC technology are not successful, or we fail to
obtain necessary governmental approvals, we are unlikely to attain profitability

We have invested a significant
portion of our time and financial resources in the development and commercialization of
our core SDC technology. Although we believe SDC has applications in multiple industries,
we expect that sales of SDC will constitute a substantial portion, or all, of our revenues
in future periods. Any material decrease in the overall level of sales or expected sales
of, or the prices for, SDC, whether as a result of competition, change in customer demand,
or any other factor, would have a materially adverse effect on our business, financial
condition and results of operations.

22

---



We are marketing our new
antimicrobial silver ion technology to industrial and consumer markets. These products
have not yet been accepted into the marketplace, and may never be accepted. In addition,
even if our products achieve market acceptance, we may not be able to maintain product
sales or other forms of revenue over time if new products or technologies are introduced
that are more favorably received than our products, are more cost-effective or otherwise
render our products less attractive or obsolete. Other risks involved in introducing these
new products include liability for product effectiveness and safety, and competition from
existing or emerging sources. Additionally, government regulation in the U.S. and in other
countries is a significant factor in the development, manufacturing and marketing of many
of our products and in our ongoing research and development activities. All products
derived from SDC require approval by government agencies prior to marketing or sale in the
U.S. or overseas. Complying with applicable government regulations and obtaining necessary
clearances or approvals can be time consuming and expensive, and there can be no assurance
that regulatory review will not involve delays or other actions adversely affecting the
marketing and sale of our products. For example, regulatory review of SDC by the U.S. EPA
has historically been time consuming and expensive, due primarily, we believe, to the
novel nature of our technology. While we cannot accurately predict such regulatory
processes, we expect the review process to remain time consuming and expensive as we, or
our partners, apply for approval to market new formulations or to make additional claims.
We also cannot predict the extent or impact of future legislation or regulation in the
U.S. or overseas.

Some of our new bioscience
applications for healthcare markets, food preparation markets and agriculture markets will
also require approval by government agencies prior to marketing or sale in the U.S. or
overseas. Until we, or our partners, obtain approvals from the appropriate regulatory
authorities for future potential product applications, if ever, we will not be able to
market or sell such products, which would limit our revenues. Even after approval, if any,
we will remain subject to changing governmental policies regulating antimicrobial
products.

If we are not able to manage our
anticipated growth effectively, we may not become profitable

We anticipate that expansion will
continue to be required to address potential market opportunities for our SDC technology.
There can be no assurance that our infrastructure will be sufficiently scalable to manage
any future growth. There also can be no assurance that if we continue to expand our
operations, management will be effective in expanding our physical facilities or that our
systems, procedures or controls will be adequate to support such expansion. In addition,
we will need to provide additional sales and support services to our partners if we
achieve our anticipated growth with respect to the sale of our SDC technology for various
applications. Failure to properly manage an increase in customer demands could result in a
material adverse effect on customer satisfaction, our ability to perform on new contracts
and on our operating results.

The industries in which we operate
are heavily regulated and we may be unable to compete effectively

We are a bioscience company focused
on the marketing and continued development of our electrolytically generated stabilized
ionic silver technology, including our flagship SDC antimicrobial. While the rewards in
these fields are potentially great, the risks, regulatory hurdles and costs of doing
business in our target markets are high. Our SDC is a platform technology rather than a
single use applied technology. As such, products developed from the platform fall under
the jurisdiction of multiple U.S. and international regulatory agencies. We currently have
U.S. EPA registration for our 2400-parts per million (ppm) technical grade SDC concentrate
(trade name Axenohl), as well as for our Axen and Axen30 hard surface disinfectant
products for commercial, industrial and consumer applications including restaurants, homes
and medical facilities. We intend to fund and manage additional U.S. EPA-regulated product
development internally, in conjunction with our regulatory consultants and potentially by
partnering with other third parties. We are also partnering, or intend to partner, with
third parties who are seeking, or intend to seek, approvals to market SDC-based products
in markets outside the U.S. However, the introduction of additional regulated
antimicrobial products in the U.S. or in markets outside the U.S. could take several
years, or may never be achieved. In addition, doing business internationally carries a
great deal of risk with regard to foreign government regulation, banking, currency
fluctuation, and many other factors.

# We are subject to
intense competition

Our silver ion and other products
compete in highly competitive markets dominated by extremely large, well financed
domestically and internationally recognized chemical and pharmaceutical companies. Many of
our competitors have greater financial resources than we do in the areas of sales,
marketing, branding and product development and we expect to face additional competition
from these competitors in the future. Many of our competitors already have well
established brands and distribution. Focused competition by chemical and pharmaceutical
giants could substantially limit or eliminate our potential market share and ability to
profit from our products and technologies. Our ability to compete will depend upon our
ability, and the ability of our distributors and other partners, to develop brand
recognition and novel distribution methods, and to displace existing, established and
future products in our relevant target markets. We or our partners or distributors may not
be successful in doing so.

We rely on a small number of key
supply ingredients in order to manufacture our products

All of the supply ingredients used to
manufacture our products are readily available from multiple suppliers. However, commodity
prices for these ingredients can vary significantly and the margins that we are able to
generate could decline if prices rise. For example, both silver and citric acid prices
have risen recently. A decision is expected imminently by the European Commission on an
antidumping action against Chinese citric acid producers, a dominant force in the global
citric acid market, which has caused global citric acid price increases in anticipation of
antidumping duties that the European Commission could impose on Chinese producers. Any
measures could be followed by similar action from the authorities in the U.S. In many of
our distribution and development agreements, we are unable to raise our product prices to
our customers quickly to maintain our margins, and significant price increases for key
inputs would therefore have an adverse effect on our results of operations.

23

---



If we are unable to successfully
develop or commercialize new applications of our SDC technology, our operating results
will suffer

In addition to its use on inanimate
surfaces, we believe that our SDC technology also shows promise as a broad-spectrum
antimicrobial for use in human and veterinary healthcare products. We plan to pursue
additional U.S. EPA and FDA regulatory approvals for other applications. We have entered
into agreements with FTA Therapeutics for the development and commercialization of certain
FDA regulated SDC-based products. However, we do not exercise any control over these
development partners. FTAs resources are limited and progress to date on all
indications has been slow. The FDA and comparable agencies in many foreign countries
impose substantial limitations on the introduction of new products through costly and
time-consuming laboratory and clinical testing and other procedures. The process of
obtaining FDA and other required regulatory approvals is lengthy, expensive and uncertain.
There is no guarantee that either our existing or any other potential partner, or we, will
be able to obtain the resources necessary to further develop our technology or obtain
regulatory approvals, or that the products will be successful in meeting the strict
criteria imposed by the FDA. It may be several years before we, or any third party to whom
we grant rights to use our silver ion technologies, are able to introduce any FDA
regulated antimicrobial pharmaceutical products containing our technology. Such products
may never achieve regulatory approval and may never be commercialized. If they are
commercialized, we may not receive a share of future revenues that provides an adequate
return on our historical or future investment.

Our ability to generate increased
revenue depends in part upon the ability and willingness of our current and potential
strategic partners in both FDA and non-FDA environments to increase awareness of our
solution to their customers and provide implementation services. If our strategic partners
fail to increase awareness of our solution or to assist us in getting access to
decision-makers, then we may need to increase our marketing expenses, change our marketing
strategy or enter into marketing relationships with different parties, any of which could
impair our ability to generate increased revenue or to generate profits from our
technology.

Because we are an early stage
company, it is difficult to evaluate our prospects, our financial results may fluctuate
and these fluctuations may cause our stock price to fall

Since acquiring the rights to our SDC
technology, we have encountered and likely will continue to encounter risks and
difficulties associated with new and rapidly evolving markets. These risks include the
following, among others:

| |  | we
may not increase our sales to our existing customers and expand our customer base;
| | - | -------------------------------------------------------------------------------------

| |  | we
may not succeed in maintaining and expanding our current sales and in penetrating other
         markets and applications of our SDC technology;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------

| |  | we
may not establish and maintain effective marketing programs and continue to build our
brand          identity;
| | - | -----------------------------------------------------------------------------------------------------------------

| |  | we
may not attract and retain key business development, technical and management personnel;
| | - | -------------------------------------------------------------------------------------------

| |  | we
may not succeed in locating strategic partners and licensees of our technology; and
| | - | --------------------------------------------------------------------------------------

| |  | we
may not effectively manage our anticipated growth.
| | - | -----------------------------------------------------

In addition, because of our limited
operating history and the early stage of the market for our SDC technology, we have
limited insight into trends that may emerge and affect our business. Forecasting future
revenues is difficult, especially since our technology is novel and we are at the early
stages of the adoption of the technology. Market acceptance of our products may change
rapidly. In addition, our customer base is highly concentrated. Fluctuations in the buying
patterns of our current or potential customers for any reason, could significantly affect
the level of our sales on a period to period basis. As a result, our financial results
could fluctuate to an extent that may not meet market expectations and that also may
adversely affect our stock price. There are a number of other factors that could cause our
financial results to fluctuate unexpectedly, including product sales, the mix of product
sales, the cost of product sales, the achievement and timing of research and development
and regulatory milestones, changes in expenses, including non-cash expenses such as the
fair value of stock options granted, and manufacturing or supply issues, among other
issues.

We have no product distribution
experience and we expect to rely on third parties who may not successfully sell our
products

We have no product distribution
experience and currently rely and plan to rely primarily on product distribution
arrangements with third parties, including our collaborators. We also plan to license our
technology to certain third parties for commercialization of certain applications. We
expect to enter into additional distribution agreements and licensing agreements in the
future, and we may not be able to enter into these additional agreements on terms that are
favorable to us, if at all. In addition, we may have limited or no control over the
distribution activities of these third parties. These third parties could sell competing
products and may devote insufficient sales efforts to our products. As a result, our
future revenues from sales of our products, if any, will depend on the success of the
efforts of these third parties.

24

---



If we are unable to obtain,
maintain or defend patent and other intellectual property ownership rights relating to our
technology, we may not be able to develop and market products based on our technology,
which would have a material adverse impact on our results of operations and the price of
our common stock

We rely and expect in the future to
rely on a combination of patent, trademark, trade secret and copyright law, and
contractual restrictions to protect the proprietary aspects of our technology and
business. These legal protections afford only limited protection for our intellectual
property and trade secrets. Despite efforts to protect our proprietary rights,
unauthorized parties may attempt to copy aspects of our proprietary technology or
otherwise obtain and use information that we regard as proprietary. As a result, we cannot
be assured that our means of protecting our proprietary rights will be adequate.

We have filed for U.S. and foreign
patent applications and trademark registrations for our patents and trademarks. We may not
be successful in obtaining these patents and trademarks, and we may be unable to obtain
additional patent and trademark protection in the future. Furthermore, legal standards
relating to the validity, enforceability and scope of protection of intellectual property
rights are uncertain. It is possible that, despite our efforts, competitors or others will
create and use products in violation of our patents and/or adopt service names similar to
our service names or otherwise misappropriate our intellectual property. Such patent
infringement or misappropriation could have a material adverse effect on our business. Any
unauthorized production of our SDC-based products, whether in the U.S. or overseas, would
or could reduce our own sales of SDC-based products, thereby reducing, perhaps
significantly, our actual or potential profits. Adopting similar names and trademarks by
competitors could lead to customer confusion. Any claims or customer confusion related to
our trademarks could negatively affect our business.

Litigation may be necessary to
enforce our intellectual property rights and protect our trade secrets. If third parties
prepare and file applications in the U.S. or other countries that claim trademarks used or
registered by us, we may oppose those applications and may be required to participate in
proceedings before the regulatory agencies who determine priority of rights to such
trademarks. Any litigation or adverse priority proceeding could result in substantial
costs and diversion of resources, and could seriously harm our business and operating
results. If we are found to have violated the trademark, trade secret, copyright, patent
or other intellectual property rights of others, such a finding could result in the need
to cease use of a trademark, trade secret, copyrighted work or patented invention in our
business and the obligation to pay a substantial amount for past infringement. It could
also be necessary for us to pay a substantial amount in the future if the rights holders
are willing to permit us to continue to use the intellectual property rights. Either
having to cease use or pay such amounts could make us much less competitive and could have
a material adverse impact on our business, operating results and financial condition.

To the extent that we operate
internationally, the laws of foreign countries may not protect our proprietary rights to
the extent as do the laws of the U.S. Many countries have a first-to-file
trademark registration system. As a result, we may be prevented from registering or using
our trademarks in certain countries if third parties have previously filed applications to
register or have registered the same or similar trademarks. Our means of protecting our
proprietary rights may not be adequate, and our competitors could independently develop
similar technology.

# We may become subject to
product liability claims

As a business which manufactures and
markets products for use by consumers and institutions, we may become liable for any
damage caused by our products, whether used in the manner intended or not. Any such claim
of liability, whether meritorious or not, could be time-consuming and/or result in costly
litigation. Although we maintain general liability insurance, our insurance may not cover
potential claims of the types described above and may not be adequate to indemnify for all
liabilities that may be imposed. Any imposition of liability that is not covered by
insurance or is in excess of insurance coverage could harm our business and operating
results, and you may lose some or all of any investment you have made, or may make, in our
common stock.

# Litigation may harm our
business or otherwise distract our management

Substantial, complex or extended
litigation could cause us to incur major expenditures and distract our management. For
example, lawsuits by employees, former employees, shareholders, partners, customers, or
others, could be very costly and substantially disrupt our business. Such lawsuits could
from time to time be filed against either the Company or our officers and directors, who
are or may be indemnified by the Company for their actions in their capacity as officers
and directors. Such lawsuits are not uncommon, and we cannot assure you that we will
always be able to resolve such legal disputes on terms favorable to the Company.

Maintaining compliance with our
obligations as a public company may strain our resources and distract management, and if
we do not remain compliant our stock price may be adversely affected

Our common stock is registered under
the Securities Exchange Act of 1934, as amended (the Exchange Act). It is
therefore subject to the information, proxy solicitation, insider trading and other
restrictions and requirements of the SEC under the Exchange Act. The SEC continues to
issue new and proposed rules, and complying with existing and new rules results in
significant costs to us of being a public company, including substantial costs during the
fiscal year ending July 31, 2009 and in future years. In addition, in April 2008 we
obtained a listing of our common stock on the NASDAQ Capital Market, adding the additional
cost and administrative burden of maintaining such a listing. These additional regulatory
costs and requirements will reduce our future profits or increase our future losses, and a
greater proportion of management time and effort will be needed to meet our regulatory
obligations than before.

25

---



We are required to evaluate our
internal controls systems in order to allow management to report on our internal controls
as required by Section 404 of the Sarbanes-Oxley Act. Based on the market capitalization
of our common stock at January 31, 2009, we met the defined requirements for remaining an
accelerated filer, which require us to attest to, and have our Independent Registered
Public Accounting Firm attest to, our internal controls. We are also required to file our
annual and quarterly reports with the Securities and Exchange Commission (SEC)
on an accelerated basis. Recent SEC pronouncements suggest that in the next several years
we may be required to report our financial results using new International Financial
Reporting Standards, replacing U.S. GAAP, which would require us to make significant
investments in training, hiring, consulting and information technology, among other
investments. All of these and other reporting requirements and heightened corporate
governance obligations that we will face or are already facing will further increase the
cost to us, perhaps substantially, of remaining compliant with our obligations under the
Exchange Act and the Sarbanes-Oxley Act. In order to meet these incremental obligations,
we will need to invest in our corporate and accounting infrastructure and systems, and
acquire additional services from third party advisors. As a result of these requirements
and investments, we will incur significant additional expenses and will suffer a
significant diversion of managements time. There is no guarantee that we will be
able to continue to meet these obligations in a timely manner, and we could therefore be
subject to sanctions or investigation by regulatory authorities such as the SEC or the
NASDAQ Capital Market. Any such actions could adversely affect our financial results and
the market price of our common stock, perhaps significantly.

Our publicly-filed reports are
reviewed from time to time by the SEC, and any significant changes or amendments required
as a result of any such review may result in material liability to us and may have a
material adverse impact on the trading price of our common stock

The reports of publicly-traded
companies are subject to review by the SEC from time to time for the purpose of assisting
companies in complying with applicable disclosure requirements, and the SEC is required,
pursuant to the Sarbanes-Oxley Act of 2002, to undertake a comprehensive review of a
companys reports at least once every three years. SEC reviews may be initiated at
any time. While we believe that our previously filed SEC reports comply, and we intend
that all future reports will comply in all material respects, with the published rules and
regulations of the SEC, we could be required to modify, amend or reformulate information
contained in prior filings as a result of an SEC review. Any modification, amendment or
reformulation of information contained in such reports could be significant and result in
material liability to us and have a material adverse impact on the trading price of our
common stock.

We are dependent on our management
team, and the loss of any key member of this team may prevent us from achieving our
business plan in a timely manner

Our success depends largely upon the
continued services of our executive officers and other key personnel. Our executive
officers and key personnel could terminate their employment with us at any time without
penalty. We do not maintain key person life insurance policies on our executive officers
or other employees, other than Michael L. Krall, our President and Chief Executive
Officer. The policy we have on Mr. Krall would likely not provide a benefit sufficient to
offset the financial losses resulting from the loss of Mr. Kralls future services.
The loss of one or more of our key employees could seriously harm our business, results of
operations and financial condition. We cannot assure you that in such an event we would be
able to recruit qualified personnel able to replace these individuals in a timely manner,
or at all, on acceptable terms.

Because competition for highly
qualified business development and bioengineering personnel is intense, we may not be able
to attract and retain the employees we need to support our planned growth

To successfully meet our objectives,
we must continue to attract and retain highly qualified business development and
bioengineering personnel with specialized skill sets focused on our industry. Competition
for qualified business development and bioengineering personnel can be intense. Our
ability to meet our business development objectives will depend in part on our ability to
recruit, train and retain top quality people with advanced skills who understand our
industry. In addition, it takes time for our new business development personnel to become
productive, particularly with respect to obtaining major customer accounts. If we are
unable to hire or retain qualified business development and bioengineering personnel, it
will be difficult for us to sell our products or to license our technology, and we may
experience a shortfall in revenue and not achieve our anticipated growth.

Anti-takeover provisions under our
charter documents and California law could delay or prevent a change of control and could
also limit the market price of our stock

Certain provisions of our charter and
by-laws may delay or frustrate the removal of incumbent directors and may prevent or delay
a merger, tender offer, or proxy contest involving us that is not approved by our Board of
Directors (the Board), even if such events may be beneficial to the interests
of shareholders. For example, our Board, without shareholder approval, has the authority
and power to issue all authorized and unissued shares of common stock which have not
otherwise been reserved for issuance, on such terms as the Board determines. The Board
could also issue 5,000,000 shares of preferred stock and such preferred stock could have
voting or conversion rights which could adversely affect the voting power of the holders
of our common stock. In addition, California law contains provisions that have the effect
of making it more difficult for others to gain control of the Company.

Our management and our Board of
Directors has significant influence over our direction and policies, and may be able to
delay or prevent a change of control of our Company, which could adversely affect our
stock price

As of March 10, 2009, Michael L.
Krall, our President and Chief Executive Officer, beneficially owned, including
exercisable options, approximately 6.7% of our common stock. As of the same date, our
directors and officers as a group beneficially owned, including exercisable options and
warrants, approximately 21.8% of our common stock. As a result, our management, and Mr.
Krall in particular, are in a position to significantly influence our direction and
policies, the election of our Board, and the outcome of any other matters requiring
shareholder approval. This concentration of ownership may harm the market price of our
common stock by, among other things:

26

---



| |  | delaying,
deferring, or preventing a change in control of our Company;
| | - | ----------------------------------------------------------------------

| |  | impeding
a merger, consolidation, takeover, or other business combination involving our
               Company; or
| | - | ------------------------------------------------------------------------------------------------------------------

| |  | discouraging
a potential acquirer from making a tender offer or otherwise attempting to obtain control
of our Company.
| | - | ----------------------------------------------------------------------------------------------------------------------

The price of our common stock may
be volatile, which may cause investment losses for our shareholders

Since our initial public offering in August
1996, the price and trading volume of our common stock have been highly volatile. The
price has ranged from below $1 per share to over $8 per share, and the monthly trading
volume has varied from under 200,000 shares to over 7.8 million shares. During the twelve
months prior to March 10, 2009, the closing price of our common stock on any given day has
ranged from $1.80 to $8.50 per share, and the monthly trading volume has varied from
approximately 1.2 million shares to approximately 7.9 million shares. In the future, the
market price of our common stock may be volatile and could fluctuate substantially due to
many factors, including:

| |  | actual
or anticipated fluctuations in our results of operations;
| | - | ----------------------------------------------------------------

| |  | the
introduction of new products or services, or product or service enhancements by us or our
         competitors;
| | - | -------------------------------------------------------------------------------------------------------------------

| |  | developments
with respect to our or our competitors' intellectual property rights or regulatory
         approvals or denials;
| | - | ------------------------------------------------------------------------------------------------------------------------------

| |  | announcements
of significant acquisitions or other agreements by us or our competitors;
| | - | ---------------------------------------------------------------------------------------

| |  | the
sale by us of our common or preferred stock or other securities, or the anticipation of
         sales of such securities;
| | - | ------------------------------------------------------------------------------------------------------------------------------

| |  | sales
or anticipated sales of our common stock by our insiders (management and directors);
| | - | ------------------------------------------------------------------------------------------

| |  | the
trading volume of our common stock, particularly if such volume is light;
| | - | -----------------------------------------------------------------------------

| |  | conditions
and trends in our industry;
| | - | --------------------------------------

| |  | changes
in our pricing policies or the pricing policies of our competitors;
| | - | ---------------------------------------------------------------------------

| |  | changes
in the estimation of the future size and growth of our markets and, among other
         factors;
| | - | ---------------------------------------------------------------------------------------------------------

| |  | general
economic conditions.
| | - | ----------------------------

In addition, the stock market in
general, the NASDAQ Capital Market, and the market for shares of novel technology and
biotechnology companies in particular, have experienced extreme price and volume
fluctuations that have often been unrelated or disproportionate to the operating
performance of those companies. Further, the market prices of bioscience companies have
been unusually volatile in recent months, and many economists expect such unusual
volatility to continue for the foreseeable future. These broad market and industry factors
may materially harm the market price of our common stock, regardless of our operating
performance. In the past, following periods of volatility in the market price of a
companys securities, shareholder derivative lawsuits and securities class action
litigation have often been instituted against that company. Such litigation, if instituted
against the Company or our officers and directors, could result in substantial costs and a
diversion of managements attention and resources. In addition, this volatility could
adversely affect an investors ability to sell shares of our common stock and/or the
available price for such shares, and could result in lower prices being available to an
investor if the investor wishes to sell their shares at any given time.

Our future capital needs are
uncertain, and we may need to raise additional funds in the future which may not be
available on acceptable terms or at all

Our capital requirements will depend
on many factors, including:

| |  | acceptance
of, and demand for, our products;
| | - | --------------------------------------------

| |  | the
success of strategic partners in selling our products;
| | - | ----------------------------------------------------------

| |  | the
costs of further developing our existing, and developing new, products or technologies
| | - | ------------------------------------------------------------------------------------------

| |  | the
extent to which we invest in new technology and product development;
| | - | ------------------------------------------------------------------------

| |  | the
number and timing of acquisitions and other strategic transactions; and
| | - | ---------------------------------------------------------------------------

| |  | the
costs associated with the continued operation, and any future growth, of our business.
| | - | ------------------------------------------------------------------------------------------

Our existing sources of cash and cash
flows may not be sufficient to fund our activities. As a result, we may need to raise
additional funds, and such funds may not be available on favorable terms, or at all.
Furthermore, if we issue equity or convertible debt securities to raise additional funds,
our existing shareholders may experience dilution, and the new equity or debt securities
may have rights, preferences, and privileges senior to those of our existing shareholders.
If we incur additional debt, it may increase our leverage relative to our earnings or to
our equity capitalization. If we cannot raise funds on acceptable terms, we may need to
scale back our expenditures through reductions in our workforce and operations, and we may
not be able to develop or enhance our products, execute our business plan, take advantage
of future opportunities, or respond to competitive pressures or unanticipated consumer
requirements.

# We may not be able to
maintain our NASDAQ listing

In April 2008, we obtained a listing
for our common stock on the NASDAQ Capital Market. In order to maintain our listing, we
will need to continue to meet certain minimum listing standards that include, or may
include, our shareholders equity, the market value of our listed or publicly held
securities, the number of publicly held shares, our net income, a minimum bid price for
our common stock, the number of shareholders, the number of market makers, and certain of
our corporate governance policies. If we fail to maintain the standards required now or in
future by the NASDAQ Capital Market, our common stock could be delisted from the NASDAQ
Capital Market. Such delisting could cause our stock to be classified as penny
stock,, among other potentially detrimental consequences, any of which could
significantly impact your ability to sell your shares or to sell your shares at a price
that you may deem to be acceptable.

If outstanding options and
warrants to purchase shares of our common stock are exercised, or if other remaining
authorized shares of our common stock are issued, the interests of our shareholders could
be diluted

We have approximately 6,746,800
shares of common stock reserved for issuance, which includes shares under equity
compensation plans, vested and unvested options, and warrants. These shares have a
weighted-average exercise price of approximately $2.24. In addition, approximately
12,550,000 authorized shares of our common stock remain available for future issuance
under equity compensation plans or otherwise. The exercise of options and warrants, and
the sale of shares underlying such options or warrants, could have an adverse effect on
the market for our common stock, including the price that an investor could obtain for
their shares. Investors may experience dilution in the net tangible book value of their
investment upon the exercise of outstanding options and warrants granted under our stock
option plans, and options and warrants yet to be granted or issued.

We may not be able to utilize all
of, or any of, our tax net operating loss carry-forwards and our future after-tax
earnings, if any, could be reduced

At January 31, 2009, we had federal
and California tax net operating loss carry-forwards of approximately $40,350,300 and
$30,753,800 respectively. The difference between federal and California tax loss
carry-forwards is primarily due to limitations on California loss carry-forwards.

Utilization of the net operating loss
carry-forwards may be subject to a substantial annual limitation due to ownership change
limitations that may have occurred or that could occur in the future, as required by
Section 382 of the Internal Revenue Code as well as similar state provisions. These
ownership changes may limit the amount of net operating loss carry-forwards that can be
utilized annually to offset future taxable income and tax, respectively. In general, an
ownership change, as defined by Section 382 of the Internal Revenue Code results from a
transaction or series of transactions over a three-year period resulting in an ownership
change of more than 50 percentage points of the outstanding stock of a company by certain
stockholders or public groups. Since the Companys formation, we have raised capital
through the issuance of capital stock on several occasions (both before and after our
initial public offering in 1996) which, combined with the purchasing shareholders
subsequent disposition of those shares, may have resulted in such an ownership change, or
could result in an ownership change in the future upon subsequent disposition. While we
believe that the Company has not experienced an ownership change, the pertinent tax rules
related thereto are complex and subject to varying interpretations, and thus complete
assurance cannot be provided that the taxing authorities would not take an alternative
position.

In addition, our U.S. federal tax
loss carry-forwards will begin expiring in the year ending July 31, 2017 unless previously
utilized, and will completely expire in the year ending July 31, 2028. The California tax
loss carry-forwards will begin to expire in the year ending July 31, 2013 and will
completely expire in the year ending July 31, 2018. If we are unable to earn sufficient
profits to utilize the carry-forwards by these dates, they will no longer be available to
offset future profits, if any.

# We may never pay
dividends

We have never paid any cash dividends
on our common stock and do not anticipate paying cash dividends on our common stock in the
foreseeable future. The future payment of dividends on our common stock, if any, is
dependent on the discretion of our Board, our earnings, our financial condition and other
business and economic factors which our Board may consider relevant.
