The accompanying unaudited condensed consolidated financial statements of TheraSense, Inc. and its subsidiaries (TheraSense or the Company) have
been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange
Commission. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting only of normal
recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and nine month periods ended September 30, 2003 are not necessarily indicative of the results that may be expected for the year
ending December 31, 2003, or for any future period. These condensed consolidated financial statements and notes should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2002 included
in the Companys Form 10-K for the year ended December 31, 2002.



NOTE
2 - Summary of Significant Accounting Policies:



The Companys
significant accounting policies are disclosed in the Companys Annual Report on Form 10-K for the year ended December 31, 2002 that was filed with the Securities and Exchange Commission on March 27, 2003. The Companys significant
accounting policies have not materially changed since December 31, 2002.



NOTE 3 - Recent Accounting Pronouncements:



In November 2002,
the Emerging Issues Task Force (EITF) reached a consensus on Issue No. 00-21, Revenue Arrangements with Multiple Deliverables. EITF Issue No. 00-21 provides guidance on how to account for arrangements that involve the
delivery or performance of multiple products, services and/or rights to use assets. The provisions of EITF Issue No. 00-21 will apply to revenue arrangements entered into in fiscal periods beginning after June 15, 2003, including quarters. The
adoption of EITF No. 00-21 did not have a material impact on the Companys financial position, cash flows or results of operations.



In January 2003, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 46 (FIN 46), Consolidation of Variable
Interest Entities, an Interpretation of ARB No. 51. FIN 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a
controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. During October 2003, the FASB issued FASB Staff Position 46-6
(FSP 46-6), Effective Date of FASB Interpretation No. 46, Consolidation of Variable Interest Entities. FSP 46-6 is effective for financial statements issued after October 9, 2003, and provides a broad deferral of the latest
date by which all public entities must apply FIN 46 to certain variable interest entities, to the first reporting period ending after December 15, 2003. The Company does not expect the adoption of FIN 46 to have a material impact upon its financial
position, cash flows or results of operations.



In May 2003, the FASB issued
Statement of Financial Accounting Standards (SFAS) No. 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity (SFAS 150). SFAS No.150 establishes standards
for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. SFAS No. 150 requires that an issuer classify a financial instrument that is within its scope as a liability (or an asset in
some circumstances). SFAS No. 150 is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. SFAS No. 150 is to be
implemented by reporting the cumulative effect of a change in an accounting principle for financial instruments created before the issuance date of SFAS No. 150 and still existing at the beginning of the interim period of adoption. Restatement is
not permitted. The Company does not expect the adoption of SFAS No. 150 to have a material impact upon its financial position, cash flows or results of operations.



NOTE 4 - Net Income (Loss) Per Share:



Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of vested common shares outstanding for the period. Diluted net
income per share is computed giving effect to all potential dilutive common stock, including options. Options and common stock subject to repurchase were not included in the computation of diluted net loss per share because the effect would be
antidilutive.

NOTE 6 - Accrued product
warranties:



The Companys condensed consolidated financial
statements include accruals for product warranty claims. The Company provides a five-year warranty on its FreeStyle meters. For proper matching of these costs in the period that revenues are recognized, an estimated warranty expense accrual rate is
determined based on historical experience. Such costs are accrued at the time revenue is recognized. At September 30, 2003 and December 31, 2002, accrued product warranties totaled $1,694,669 and $1,931,935, respectively, and are included in
accrued liabilities in the accompanying condensed consolidated balance sheets.

NOTE 7 - Revolving Line of Credit
Agreement and Long-Term Debt:



In May 2002, the Company entered into a
revolving line of credit agreement with a lending company. Under the terms of the credit agreement, as amended and currently in effect, amounts the Company borrows from the lending company are repaid to the lending company directly by the
Companys accounts receivable debtors. Outstanding amounts owed to the lending company under the credit agreement are collateralized by all of the Companys assets excluding the Companys intellectual property assets. The maximum
amount the Company may borrow from the lending company is based on its eligible accounts receivable and cannot exceed $15,000,000. All outstanding amounts bear interest at the prime rate plus 0.5%. The credit agreement includes certain covenants
requiring minimum liquidity and minimum net income over time. The Company is in compliance with these covenants. As of September 30, 2003, there were no borrowings outstanding under the credit agreement.



In March 2002, the Company entered into an arrangement to finance the purchase of certain
equipment the Company uses to manufacture its FreeStyle test strips with its supplier of test strip packaging vials. The purchase price of the equipment is approximately $1,600,000. From March 2002 to March 2003, the Company paid down the equipment
purchase price to the supplier through a portion of the purchase price for each packaging vial purchased from the supplier. In April 2003, the Company paid the remaining purchase price of approximately $1,500,000 for the equipment to the supplier
and took title to the equipment.



During 1998, the Company entered into an
equipment line of credit agreement with a lending company under which the Company could borrow up to $2,500,000 for equipment purchases prior to December 31, 1999. Prior to December 31, 1999, the Company borrowed a total of approximately $580,000
under this arrangement. During 1999, the Company entered into a subordinated debt agreement with this lending company under which the Company could borrow up to $5,000,000 for equipment purchases prior to July 7, 2000. The Company borrowed a
total of $5,000,000 under this arrangement. In April 2003, the Company and the lending company entered into an agreement pursuant to which the Company paid $844,451 as a compromised and final payment of all amounts then outstanding under these
arrangements, and the Company took title to all of the equipment that had been leased pursuant to these arrangements. The gain recorded from the compromised and final payment is not significant. The gain is recorded on the Interest income,
net line item of the Companys condensed consolidated statement of operations for the nine months ended September 30, 2003.



NOTE 8 - Accounting for Stock-Based Compensation:



The Company uses the intrinsic value method of Accounting Principles Board Opinion No. 25 (APB No. 25), Accounting for Stock Issued to Employees,
in accounting for its employee stock options, and presents disclosure of pro forma information, required under SFAS No. 123, Accounting for Stock-Based Compensation as amended by SFAS No. 148, Accounting for Stock-Based
Compensation, Transition and Disclosure, an amendment of FASB Statement No. 123, which amends FASB Statement No. 123.

periods ended September 30, 2003, are not necessarily indicative of the results that may be expected for any future period.



Overview



We develop, manufacture and sell easy to use glucose self-monitoring systems that dramatically reduce the pain of testing for people with diabetes. We commenced commercial shipments in the United States of our first
product, FreeStyle, in June 2000. We sell FreeStyle in the United States and Canada through national retailers and wholesalers, and directly to consumers over the telephone and through our website. Ypsomed, formerly Disetronic Injection Systems,
distributes the FreeStyle system in various European countries. In Japan, Nipro Corporation, the Japanese market leader in dialysis and insulin pumps, distributes the FreeStyle system. We also sell FreeStyle in the United Kingdom through retailers
and wholesalers. Our sales of FreeStyle products in Canada and the United Kingdom are through a wholly-owned subsidiary in each country. In other international markets, we sell our products through independent distributors. In total, our products
are sold in over 40 countries around the world.



In October 2003, we
commercially introduced the FreeStyle Flash
system in the United States. The FreeStyle Flash system is based on our FreeStyle blood glucose monitoring technology. The FreeStyle Flash meter is smaller than the FreeStyle meter, and it has other new features, including a faster test time of
about seven seconds, a backlit panel display, lighted test strip port and four customizable daily alarms. The FreeStyle Flash system uses the FreeStyle test strips and FreeStyle lancets.



We manufacture our disposable test strips ourselves at our facility in Alameda, California. We outsource the manufacturing, packaging and
testing of our FreeStyle meters and FreeStyle Flash meters to Flextronics International Ltd., an electronics contract manufacturer. Our lancing devices and disposable lancets are manufactured by Facet Technologies LLC, a wholly-owned subsidiary of
Matria Healthcare, Inc. Our distribution services are performed by UPS Supply Chain Management f/d/b/a Livingston Health Care Systems Inc., a division of UPS Global Logistics.



Manufacturers typically sell their glucose monitoring system kits at discounts to list prices, offer customer rebates or provide free
product samples to expand their installed base of monitoring devices and thus increase the market for their disposable test strips and lancets. We currently distribute the FreeStyle System kit and FreeStyle Flash System kit at a financial loss due
in part to samples, discounts and rebates to establish an installed base of systems from which we expect to generate recurring revenues from our disposable FreeStyle test strips and lancets. We have been offering and expect to continue to offer
similar discounts and rebates on, and free samples of, our FreeStyle System kits and FreeStyle Flash System kits.

Revenues are generated primarily from sales of our FreeStyle System kit and from the recurring sales of disposable
FreeStyle test strips and lancets. We recognize revenue on these products upon shipment. Generally, our sales terms to retailers and wholesalers provide for customer payment within 60 days of shipment on initial orders and payment within 30 days for
subsequent orders. However, we have occasionally granted longer credit terms to match our competitors. We perform ongoing credit evaluations of our customers financial condition and, generally, require no collateral from our customers. We
believe our terms to retailers, wholesalers and end users, including rights to return and payment terms, are similar to our competitors terms.



We have incurred losses every year since 1997. We incurred net losses of $43.6 million in 2000, $52.9 million in 2001, $29.2 million in 2002 and $9.3 million for the nine
months ended September 30, 2003. As of September 30, 2003, we had an accumulated deficit of $154.1 million. The three months ended September 30, 2003 was the first profitable quarter in our history. We will need to continue to increase product
revenues and reduce product costs to sustain and increase our profitability in future periods.



Cost of revenues consists primarily of:



| |  | payments to our manufacturing and distribution partners;
| | - | --------------------------------------------------------



| |  | expenses relating to our disposable test strip manufacturing;
| | - | -------------------------------------------------------------



| |  | expenses relating to our internal operations;
| | - | ---------------------------------------------



| |  | expenses relating to our five-year warranty on our FreeStyle meter;
| | - | -------------------------------------------------------------------



| |  | royalties payable under technology licenses; and
| | - | ------------------------------------------------



| |  | amortization of deferred stock-based compensation.
| | - | --------------------------------------------------



Research and development expenses include costs associated with the design, development and testing of our products. All research and development costs are expensed as
incurred. These costs consist primarily of:



| |  | salaries and related personnel expenses;
| | - | ----------------------------------------



| |  | fees paid to outside service providers;
| | - | ---------------------------------------



| |  | expenditures for purchases of laboratory supplies and clinical trials;
| | - | ----------------------------------------------------------------------



| |  | overhead allocated to product development; and
| | - | ----------------------------------------------



| |  | amortization of deferred stock-based compensation.
| | - | --------------------------------------------------



Selling, general and administrative expenses primarily consist of:



| |  | salaries, commissions and related expenses for personnel engaged in sales, marketing, customer service and administrative functions;
| | - | ------------------------------------------------------------------------------------------------------------------------------------



| |  | costs associated with advertising, product sampling, trade shows, promotional and other marketing activities;
| | - | -------------------------------------------------------------------------------------------------------------



| |  | general corporate expenses;
| | - | ---------------------------



| |  | legal and regulatory expenses; and
| | - | ----------------------------------



| |  | amortization of deferred stock-based compensation.
| | - | --------------------------------------------------



We estimate the uncollectability of our accounts receivable. In doing so, we analyze historical bad debts, customer concentrations, customer credit-worthiness, current
economic trends and changes in customer payment terms.



We have recorded
deferred stock-based compensation in connection with stock option grants and sales of restricted stock to employees at exercise or sales prices below the deemed fair market value of our common stock. Deferred stock-based compensation for options
granted to non-employees has been determined as the fair value of the equity instruments issued. Deferred stock-based compensation for options granted to non-employees is periodically remeasured as the underlying options vest. As of September 30,
2003 we have recorded aggregate deferred stock-based compensation of $24.3 million, of which $6.7 million remains and will be amortized to expense on a straight-line basis through 2005. This amount is being amortized over the respective vesting
periods of these equity instruments, which is typically four years. Stock-based compensation expense has been allocated according to employees and their respective departments and by function for non-employees.



Critical Accounting Policies and Estimates



Our critical accounting policies and estimates are disclosed in the our Annual Report on
Form 10-K for the year ended December 31, 2002 that was filed with the Securities and Exchange Commission on March 27, 2003. Our critical accounting policies and estimates have not materially changed since December 31, 2002.

Revenues.Total revenues
were $58.2 million for the three months ended September 30, 2003 as compared to $39.0 million for the comparable period of 2002, an increase of $19.2 million or 49%. The increase was due primarily to greater sales of FreeStyle test strips and
FreeStyle System kits. During the three months ended September 30, 2003, we recognized revenues of $0.6 million relating to the $15.0 million payment we received from the Disetronic Group in January 2003 in connection with the amendment of our
international distributor agreement. The balance of the $15.0 million payment is reflected in the current and long-term deferred revenue line items of our condensed consolidated balance sheet. Two of our customers, McKesson, and Cardinal,
individually accounted for more than 10% and collectively 25% of our revenues for the three months ended September 30, 2003. Two of our customers, McKesson and Ypsomed (f/d/b/a Disetronic Injections Systems), individually accounted for more than 10%
and collectively 24% of our total revenues for the three months ended September 30, 2002.



Cost of revenues.Cost of revenues were $22.9 million for the three months ended September 30, 2003 as compared to $18.4 million for the comparable period of 2002, an increase of $4.5 million or 24%.
This increase is attributable to higher revenues in the current period versus the comparable period in 2002. As a percentage of total revenues, cost of revenues was 39% for the three months ended September 30, 2003 as compared to 47% for the
comparable period of 2002. The decrease is primarily attributable to the lower system kit manufacturing costs achieved by transitioning the FreeStyle meter manufacturing to China. Our FreeStyle meter manufacturing costs decreased by 25% for the
three months ended September 30, 2003 versus the comparable period of 2002. Since the manufacturing transition is complete, we expect that the cost of revenues attributable to FreeStyle system kit manufacturing costs, as a percentage of total
revenues, will decrease at more moderate rates in future periods. Our FreeStyle test strip manufacturing costs also decreased during the three months ended September 30, 2003. Our FreeStyle test strip manufacturing costs decreased by 12% for the
three months ended September 30, 2003 versus the comparable period of 2002. Our warranty expenses also decreased during the three months ended September 30, 2003 primarily due to the decreased cost of the replacement product. We expect that our cost
of revenues, as a percentage of total revenues, in future periods will be relatively level with the three months ended September 30, 2003 due in part to the increased cost of our FreeStyle Flash meter. This increased cost is due in part to the
FreeStyle Flash meters increased features. Amortization of deferred stock-based compensation reported in cost of revenues was $0.1 million for both three month periods ended September 30, 2003 and September 30, 2002.



Gross profit.Gross profit increased to $35.3 million for the three months
ended September 30, 2003 from $20.7 million for the comparable period of 2002, an increase of $14.6 million or 71%. The gross margin for the three months ended September 30, 2003 was 61% compared to 53% for the comparable period in 2002. Our
improved gross margin for the 2003 period resulted from reduced system kit manufacturing costs, test strip revenue composing a greater proportion of total revenue, a greater proportion of our product sales being made to retailers and wholesalers in
the United States, fixed costs being spread over larger sales volumes and reduced test strip manufacturing costs. Our 2003 period gross margin was favorably impacted by the recognition of the $0.6 million of revenue during the period from the $15.0
million payment we received from the Disetronic Group.

Research and development expenses. Research and development expenses decreased to $5.1 million for the
three months ended September 30, 2003 from $5.3 million for the three months ended September 30, 2002, representing a decrease of $ 0.2 million, or 3%. This decrease was primarily attributable to reduced product development and clinical trial
spending in the 2003 period partially offset by increases in personnel related expenses. Product development and clinical trial expenses were greater during the comparable period of 2002 primarily due to building product in connection with and
conducting our clinical trials for Navigator, our continuous glucose monitoring system. Personnel expenses were greater during the three months ended September 30, 2003 versus the comparable period of 2002 primarily due to an increase in the number
of employees in our research and development department. As a percentage of total revenues, research and development expenses were 9% for the three months ended September 30, 2003 as compared to 14% for the comparable period of 2002. The decrease is
primarily attributable to greater total revenues for the three months ended September 30, 2003 versus the comparable period of 2002. Amortization of deferred stock-based compensation was $0.3 million for both three month periods ended September 30,
2003 and 2002. We expect research and development spending to increase in absolute dollars over the next several years as we expand our research and development activities to support our current and future products, including Navigator. We
anticipate that research and development expenses for 2004 will be approximately 10% of full year revenues.



Selling, general and administrative expenses. Selling, general and administrative expenses increased to $27.7 million for the three months ended September 30, 2003 from $25.0 million for the three months
ended September 30, 2002, representing an increase of $2.7 million, or 11%. This increase was primarily attributable to increases in marketing and promotional expenses and increases in personnel related expenses. As a percentage of total revenues,
selling, general and administrative expenses were 48% for the three months ended September 30, 2003 as compared to 64% for the comparable period of 2002. The decrease is primarily attributable to greater total revenues for the three months ended
September 30, 2003 versus the comparable period of 2002 and reductions in the cost of our product samples. Amortization of deferred stock-based compensation was $1.0 million for the three month period ended September 30, 2003 and $1.1 million for
the three month period ended September 30, 2002. We expect our selling, general and administrative expenses to remain at approximately the same absolute dollar level for the next quarter as the quarter ended September 30, 2003. We anticipate
that our selling, general and administrative expenses for 2004 will be in the range of 45%  47% of full year revenues.



Interest income, net. Net interest income decreased to $0.2 million for the three months ended September 30, 2003 from $0.3 million for the three months
ended September 30, 2002. This decrease was primarily attributable to lower interest rates on our cash, cash equivalents, and investment balances in the current period, partially offset by a decrease in interest expense as we paid off debt during
the current period. Cash, cash equivalents, and investments at September 30, 2003 were $83.5 million compared to $85.4 million at September 30, 2002.



Nine Months Ended September 30, 2003 and 2002



Non-GAAP financial information due to impact in 2002 of achieving ability to estimate product return rates. Prior to the quarter ending June 30, 2002 we did
not have a sufficient historical basis from which we could estimate product return rates. Accordingly, we deferred recognition of revenue on products shipped to retailers and wholesalers until they were resold to end users and any rights of return
had expired. We estimated end user purchases based on data provided to us by third-party data providers. Product shipments that were not recognized as revenue were recorded as deferred revenues on our condensed consolidated balance sheets. The
associated cost of these deferred revenues were recorded as deferred cost of products sold on our balance sheets.



Commencing with the quarter ending June 30, 2002 we achieved the ability to estimate product return rates. This event caused a $20.4 million increase in total revenues
for the second quarter of 2002 due to the recognition of previously deferred revenues. There was a corresponding $4.2 million increase to our gross profit for the second quarter of 2002 and our gross margin for the period was adversely impacted
because the deferred revenues were comprised primarily of lower margin system kits rather than test strips. Similarly, our loss from operations was favorably impacted by the gross profit from the previously deferred revenue which mitigated the loss.
The impact of this event is reflected in the condensed consolidated statement of operations data for the nine months ended September 30, 2002 presented in this report.

second quarter of 2002, we have provided the non-GAAP financial information set forth in the tables below. We believe
this non-GAAP financial information is useful supplemental information which facilitates meaningful comparisons of operational performance for the fiscal 2002 periods that include this event, with prior and subsequent periods that do not include
this event. These non-GAAP measures are not in accordance with, or an alternative for, GAAP and may be different from non-GAAP measures used for other companies.



The following table sets forth, for the nine months ended September 30, 2002, condensed consolidated statement of operations data in
accordance with generally accepted accounting principals (GAAP) and on a non-GAAP basis adjusted to exclude the impact from achieving the ability to estimate product return rates and recognizing previously deferred revenues, costs, and
gross profit, in the second quarter of 2002. Set forth between the columns showing GAAP and non-GAAP results is a column indicating the reconciliation to the GAAP results.

The following table sets forth, for the nine months ended September 30, 2003 and 2002, the percentage of total revenues
represented by certain items reflected in our condensed consolidated statement of operations in accordance with GAAP and, for the nine months ended September 30, 2002 only, on a non-GAAP basis adjusted to exclude the impact from achieving the
ability to estimate product return rates and recognizing previously deferred revenues, costs and gross profit.

Revenues. Total revenues
were 150.1 million for the nine months ended September 30, 2003 as compared to GAAP revenues of $131.5 million for the comparable period in 2002. Non-GAAP total revenues, as shown in the table above, for the nine months ended September 30, 2002 were
$111.1 million. The increase in the total revenues for the 2003 period over the non-GAAP total revenues for the comparable period of 2002 was 35%. This increase is primarily due to greater sales of FreeStyle test strips and FreeStyle System kits.
Three of our customers, McKesson, Ypsomed, and Cardinal, individually accounted for more than 10% and collectively accounted for 31% of our total revenues from shipments in the nine months ended September 30, 2003. Two of our customers, McKesson and
Ypsomed, accounted for more than 10% and collectively accounted for approximately 20% of our total GAAP revenues from shipments in the nine months ended September 30, 2002.



Cost of revenues. Cost of revenues were $64.5 million for the nine months ended September 30, 2003 as compared to GAAP cost of
revenues of $71.2 million for the comparable period of 2002. Non-GAAP cost of revenues, as shown in the table above, for the nine months ended September 30, 2002 was $55.0 million. The increase in cost of revenues for the 2003 period over the
non-GAAP cost of revenues for the comparable period of 2002 was $9.5 million, or 17%. This increase is due to higher 2003 period GAAP revenues versus the non-GAAP revenues for the comparable period of 2002. As a percentage of total revenues, cost of
revenues was 43% for the nine months ended September 30, 2003 as compared to non-GAAP cost of revenues, as a percentage of total non-GAAP revenues of 50% for the comparable period of 2002, a decrease of 7%. The decrease is primarily attributable to
the lower system kit and test strip manufacturing costs. Amortization of deferred stock-based compensation expense reported in cost of revenues for the nine months ended September 30, 2003 was $0.4 million as compared to $0.5 million for the
comparable period of 2002.



Gross profit. Gross profit was $85.5
million for the nine months ended September 30, 2003 as compared to GAAP gross profit of $60.3 million for the comparable period of 2002. Non-GAAP gross profit, as shown in the table above, for the nine months ended September 30, 2002 was $56.1
million. The increase in gross profit for the 2003 period over the non-GAAP gross profit for the comparable period of 2002 was $29.4 million, or 52%. The GAAP gross margin for the nine months ended September 30, 2002 was 46% and the non-GAAP gross
margin for the nine months ended September 30, 2002 was 51%. The GAAP gross margin for this 2002 period was lower than the non-GAAP gross margin for the same period primarily because the GAAP gross margin included the recognition of previously
deferred revenues from sales of lower margin system kits. The gross margin for the nine months ended September 30, 2003 was 57%. The improved gross margin and gross profit for the 2003 period resulted from test strip revenue composing a greater
proportion of total revenue, reduced system kit and test strip manufacturing costs and fixed costs being spread over larger sales volumes.



Research and development expenses. Research and development expenses were $16.0 million for the nine months ended September 30, 2003 as compared to $15.8
million for the comparable period of 2002, an increase of 1%. This increase was primarily attributable to increases in personnel related expenses partially offset by reduced product development and clinical trial spending in the 2003. Personnel
expenses were greater during the nine months ended September 30, 2003 versus comparable period of 2002 primarily due to an increase in the number of employees in our research and development department. Product development and clinical trial
expenses were greater during the

comparable period of 2002 primarily due to building product in connection with and conducting our clinical trials for
Navigator. As a percentage of total revenues, research and development expenses were 11% for the nine months ended September 30, 2003. As a percentage of total Non-GAAP revenues, research and development expenses were 14% for the comparable period
of 2002. The decrease is primarily attributable to greater total revenues for the nine months ended September 30, 2003 versus the comparable period of 2002. Amortization of deferred stock-based compensation was $0.9 million for both nine month
periods ended September 30, 2003 and 2002.



Selling, general and
administrative expenses. Selling, general and administrative expenses were $79.4 million for the nine months ended September 30, 2003 as compared to $69.1 million for the comparable period of 2002, an increase of $10.3 million, or 15%. This
increase was primarily attributable to increases in advertising, promotional and marketing activity in the United States, increases in personnel related expenses, increases in expenses associated with our international sales subsidiaries and
increases in expenses associated with our outsourced customer service in the nine months ended September 30, 2003. These increases were partially offset by decreases in outside services expenses. As a percentage of total revenues, selling, general
and administrative expenses were 53% for the nine months ended September 30, 2003. As a percentage of total Non-GAAP revenues, research and development expenses were 62% for the comparable period of 2002. The decrease is primarily attributable to
greater total revenues for the nine months ended September 30, 2003 versus the comparable period of 2002. Amortization of deferred stock-based compensation was $2.9 million for the nine months ended September 30, 2003, as compared to $3.2 million in
the same prior year period.



Interest income, net.Net interest
income decreased to $0.6 million for the nine months ended September 30, 2003 from $1.1 million for the nine months ended September 30, 2002. This decrease was primarily attributable to lower interest rates on our cash, cash equivalents, and
investment balances in the current period partially offset by a decrease in interest expense as we paid off debt during the current period. In the comparable period of 2002, we had higher cash, cash equivalents, and investment balances resulting
from the net proceeds of our initial public offering in October 2001.



Liquidity and Capital Resources



On October 17, 2001, we
consummated our initial public offering of common stock in which we received net proceeds of $120.9 million. Previously, we had financed our operations primarily through private placements of convertible preferred stock resulting in net proceeds of
$119.2 million. We have also financed our operations through equipment financing arrangements and capital leases, with $2.2 million in principal outstanding at September 30, 2003.



As of September 30, 2003, our principal debt arrangements included a $2.0 million senior loan and security agreement with a lending company
at an effective interest rate of 13.1% per annum (inclusive of amortization of the fair value of warrants issued) and a $3.0 million equipment line of credit at an interest rate of 7.28% with a lending company.



In April 2003, we entered into an agreement with one of our lenders pursuant to which we paid
$844,451 to the lending company as a compromised and final payment of all amounts outstanding under this arrangement, and we took title to all of the equipment that had been leased pursuant to this arrangement.



In March 2002, we entered into an arrangement to finance the purchase of certain equipment we
use to manufacture our FreeStyle test strips with our supplier of test strip packaging vials. The purchase price of the equipment was approximately $1.6 million. From March 2002 to March 2003, we paid down the equipment purchase price to the
supplier through a portion of the purchase price for each packaging vial purchased from the supplier. In April 2003, we paid the remaining purchase price of approximately $1.5 million for the equipment to the supplier and took title to the
equipment.



In May 2002, we entered into a revolving line of credit agreement
with a lending company. Under the terms of the credit agreement as amended and currently in effect, amounts we borrow from the lending company are repaid to the lending company directly by our accounts receivable debtors. Outstanding amounts owed to
the lending company under the credit agreement are collateralized by all of our assets excluding our intellectual property assets. The maximum amount we may borrow from the lending company is based on our eligible accounts receivable and cannot
exceed $15.0 million. All outstanding amounts bear interest at the prime rate plus 0.5%. The credit agreement includes certain covenants requiring minimum liquidity and minimum net income over time. We are in compliance with these covenants. As of
September 30, 2003, there were no borrowings outstanding under the credit agreement.

In January 2003, we received a $15.0 million payment from the Disetronic Group pursuant to the amendment of our
international distributor agreement. We are recognizing this payment as revenue over the term of the international distributor agreement, which expires in December 2006, if not terminated earlier. In the nine months ended September 30, 2003, we
recognized revenue of $1.8 million from this payment.



As of September 30,
2003, we had cash, cash equivalents and investments of $83.5 million.



Cash provided by or used in operating activities.Net cash provided by operating activities was approximately $15.8 million for the nine months ended September 30, 2003. This was largely due to the $15.0 million payment from
the Disetronic Group in January 2003 pursuant to the amendment of our international distributor agreement in January 2003. In addition, decreases in inventories of $7.9 million and in prepaid expenses and other current assets of $3.2 million were
offset by increases in accounts receivable of $6.0 million, and a reduction of accounts payable of $2.4 million. Inventories decreased due to lower per unit costs on both FreeStyle System Kits and test strips plus continued improvements in
management of raw materials and work-in-process inventories. Accounts receivable increased due primarily to higher revenues. The decrease in accounts payable is due primarily to lower purchase prices we pay for our system kits. For the nine months
ended September 30, 2002, cash used in operations was $58.9 million. The difference between our net loss and our net cash used in operating activities reflected increases in accounts receivable of $18.2 million and increases in inventories of $16.2
million as well as a decrease in accrued liabilities of $4.9 million, offset by an increase in accounts payable of $5.7 million. The increase in accounts receivable principally related to the growth in revenues for the nine months ended September
30, 2002. The increase in inventories during the nine months ended September 30, 2002 occurred to support planned revenue growth for upcoming quarters, including international expansion into Canada via our wholly-owned subsidiary. Accrued
liabilities decreased as we paid royalties and bonuses that were accrued at the end of 2001. The increase in accounts payable is principally related to the growth in business operations for the nine months ended September 30, 2002.



Cash used in investing activities.Net cash used in investing activities was
approximately $19.6 million and $50.9 million for the nine month periods ended September 30, 2003 and 2002, respectively. For the nine-month period ended September 30, 2003, investing activities consisted of capital expenditures of $6.5 million,
mainly for expansion of our existing facility and increasing our test strip production capacity, and purchases of investments, net of $13.0 million. For the nine-month period ended September 30, 2002, investing activities included capital
expenditures of $8.5 million for manufacturing equipment used in the production of our disposable test strips, as we increased production capacity to meet planned growth and by purchases of investments, net of $42.4 million, as some of the proceeds
from the initial public offering in October 2001 were invested in corporate bonds, municipal securities, and governmental securities.



Cash provided by or used in financing activities.Net cash used in financing activities for the nine months ended September 30, 2003 of $3.1 million was
primarily attributable to net principal payments on long-term debt and lines of credit of $6.0 million offset by $2.8 million from proceeds from the exercise of stock options, and from the repayment of notes receivable from stockholders of $0.2
million. Net cash provided by financing activities for the nine months ended September 30, 2002 of $4.9 million was $3.9 million in proceeds from the exercise of stock options and $1.0 million net proceeds from long-term debt and lines
of credit.



We expect to have positive cash flows from operations for the
fourth quarter of 2003. We also expect increased sales and marketing expenses related to the promotion of FreeStyle and FreeStyle Flash, increased research and development expenses, as well as expenses for additional personnel and product
enhancement efforts. Our future capital requirements will depend on a number of factors, including market acceptance of FreeStyle products, the resources we devote to developing and supporting our products, continued progress of our research and
development of potential products, the need to acquire licenses to technology and the availability of other financing. Our capital expenditures for the nine months ended September 30, 2003 were $6.5 million, and we believe that our capital
expenditure for the next three months will be approximately $2.2 million.



Inflation



The impact of inflation on our business has not
been material to date.

##### Table of Contents

In January 2003, the Financial Accounting Standards Board (FASB) issued FASB Interpretation No. 46 (FIN
46), Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51. FIN 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in the entity
do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. During October 2003, the FASB
issued FASB Staff Position 46-6 (FSP 46-6), Effective Date of FASB Interpretation No. 46, Consolidation of Variable Interest Entities. FSP 46-6 is effective for financial statements issued after October 9, 2003, and provides
a broad deferral of the latest date by which all public entities must apply FIN 46 to certain variable interest entities, to the first reporting period ending after December 15, 2003. We do not expect the adoption of FIN 46 to have a material impact
upon our financial position, cash flows or results of operations.



RISK
FACTORS AFFECTING OPERATIONS AND FUTURE RESULTS



We have a history of
net losses and variable quarterly results and may not maintain profitability in the future.



We have incurred losses every year since 1997. We incurred losses of $43.6 million in 2000, $52.9 million in 2001, $29.2 million in 2002 and $9.3 million for the nine months ended September 30, 2003. As of September
30, 2003, we had an accumulated deficit of approximately $154.1 million. The quarter ended September 30, 2003 was the first profitable quarter in our history. We will need to continue to increase product revenues and reduce product costs to sustain
and increase our profitability each quarter. As a relatively new entrant to the blood glucose monitoring market that has been experiencing rapid growth, revenues and profitability can vary from quarter to quarter due to various factors, including:



| |  | changes in customer stocking and inventory levels;
| | - | --------------------------------------------------



| |  | the timing of promotions and price changes by us or our competitors; and
| | - | ------------------------------------------------------------------------



| |  | new product introductions or enhancements by us or our competitors.
| | - | -------------------------------------------------------------------



We maintain a limited inventory of finished goods and typically ship products within a short period after orders are received. Historically, customer buying patterns and
our revenue growth have caused a substantial portion of our revenues to occur in the last month of the quarter. Delays in the receipt of orders or the manufacture of product near the end of the quarter could cause quarterly revenues to fall short of
anticipated levels. Because our operating expenses are based on anticipated revenue levels and a high percentage of our expenses are relatively fixed, less than anticipated revenues for a quarter could have a significant adverse impact on our
operating results.



We expect to derive substantially all of our future
revenue from sales of FreeStyle blood glucose monitoring products and these products could fail to generate increased revenues.



Currently, the primary products we market are the FreeStyle test strips, FreeStyle System kits and FreeStyle lancets, all of which we commercially introduced in June
2000. In addition, in October 2003 we commercially introduced the FreeStyle Flash System kit. Our FreeStyle products are expected to account for substantially all of our revenues for the next several years. Accordingly, our success depends upon the
acceptance by people with diabetes, as well as health care providers and third-party payors of our FreeStyle products as a preferred blood glucose self-monitoring devices. Relative to the overall size of the blood glucose monitoring market, a
limited number of people have used our FreeStyle products, and people with diabetes or the medical community may not substantially endorse these products as a preferred blood glucose self-monitoring device. In addition, FreeStyles market
acceptance may not be sustained or may not increase on a timely basis, if at all, due to:



| |  | the significant influence of established glucose monitoring products with healthcare professionals, customers and third-party payors;
| | - | -------------------------------------------------------------------------------------------------------------------------------------



| |  | the ability of some of our competitors to price products below a price at which we can competitively manufacture and sell our products;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------



| |  | the introduction or acceptance of competing products or technologies; and
| | - | -------------------------------------------------------------------------



| |  | cost constraints.
| | - | -----------------

Furthermore, FreeStyle products may not encourage significantly more active testing, and participants in the glucose
self-monitoring market may gravitate toward more established brands. If we are unable to successfully market and sell our FreeStyle products, we may not be able to generate increased revenues or sustained profitability because we do not have
alternative products.



In addition, to encourage market acceptance of our
products, we currently distribute the FreeStyle System kit and the FreeStyle Flash System kit at a financial loss through samples, discounts and rebates. In order to generate sufficient revenues in the future, we will therefore have to rely on
recurring revenue from the repeated purchase of our FreeStyle test strips. If FreeStyle products do not gain and maintain sufficient market share to generate increased recurring revenue from the sale of our test strips, we may not achieve sustained
profitability.



We have less sales and marketing experience relative to
other companies in the blood glucose self-monitoring market and any failure to expand sales of FreeStyle will negatively impact future revenues.



We have less experience in marketing and selling our products relative to other companies in the blood glucose self-monitoring market. We received regulatory clearance
for our initial product in January 2000 and commenced commercial shipments in June 2000. Our products require a complex marketing and sales effort targeted at health care professionals, diabetes educators, people with diabetes, pharmacists, national
retailers, independent distributors and managed care plans. We have significantly expanded our sales and marketing teams in 2001, 2002 and 2003. We face significant challenges and risks in training, managing and retaining these teams, including
managing geographically dispersed efforts. In addition, we currently have only one distributor in most of Europe and one distributor in Japan. We are dependent upon the sales and marketing efforts of our third-party distributors in these large
international markets. These distributors may not commit the necessary resources to effectively market and sell our products. Further, they may not be successful in selling our products. Recently, the Disetronic Group, formerly the parent company of
our European distributor, announced that its insulin pump business was acquired by Roche Diagnostics, one of our competitors. While our European distributor was not acquired by Roche Diagnostics and will continue to distribute our products, we may
not have the level of access to Disetronics (now Roche Diagnostics) insulin pump user base that we enjoyed before the acquisition, and this could translate into decreased sales of our products. In addition, the recent amendment to the
international distributor agreement with our European distributor lowered its annual minimum purchase obligations. Our financial condition would be harmed if our marketing and sales efforts are unsuccessful.



We may not be successful in securing additional managed care contracts or implementing and
managing existing managed care contracts.



Many people with diabetes obtain
reimbursement for their purchase of glucose self-monitoring devices and test strips through managed care organizations. Accordingly, entering into reimbursement arrangements with managed care organizations is important to our business. To date, we
have entered into reimbursement arrangements with a limited number of managed care organizations, and we are actively seeking additional arrangements. Regarding our current managed care reimbursement arrangements, we have recently started the
process of implementing these arrangements throughout the managed care organizations and managing the program, including processing reimbursement submissions. If we are not successful in securing reimbursement for our products from additional
managed care organizations that cover a significant number of insured lives or we do not successfully implement and manage our reimbursement arrangements, we may have difficulty growing our business and retaining our customers. In order to obtain
reimbursement arrangements, we often agree to a net sales price lower than the net sales price we charge in other sales channels. Accordingly, unit sales within this channel must increase at a more rapid rate than other channels in order to achieve
the same revenue growth rate.



Any adverse changes in reimbursement
procedures by Medicare or other third-party payors may limit our ability to market and sell our products.



In the United States, glucose self-monitoring devices and test strips are generally covered by Medicare and other third-party payors, which provide for reimbursement of all or part of the cost of the product. Medicare
and other third-party payors are increasingly scrutinizing whether to cover new products and the level of reimbursement for covered products. FreeStyle is currently being reimbursed through Medicare, Medicaid, open formulary plans and certain
preferred provider organizations.



International market acceptance of our
products will depend, in part, upon the availability of reimbursement within prevailing health care payment systems. Reimbursement and health care payment systems in international markets vary significantly by country, and include both government
sponsored health care and private insurance. Failures to receive or maintain international reimbursement approvals may negatively impact market acceptance of our products in the applicable international markets.

##### Table of Contents

We believe that in the future, reimbursement may be subject to increased restrictions both in the United States and in
international markets. Third-party reimbursement and coverage may not be available or adequate in either the United States or international markets. Future legislation, regulation or reimbursement policies of third-party payors may adversely affect
the demand for our existing products or our products currently under development or our ability to sell our products on a profitable basis. The lack of third-party payor coverage or the inadequacy of reimbursement could have a material adverse
effect on our business, financial condition and results of operations.



We
face competition from competitors with greater resources, which may make it more difficult for us to achieve significant market penetration.



The market for blood glucose monitoring devices is intensely competitive, subject to rapid change and significantly affected by new product introductions and other market
activities of industry participants. We compete directly with Roche Diagnostics Corporation, LifeScan, Inc., a division of Johnson & Johnson, MediSense, a division of Abbott Laboratories, and Bayer AG, which currently account for approximately
90% of the worldwide sales of blood glucose self-monitoring systems. In addition, Becton, Dickinson and Company recently launched a new blood glucose monitoring system. Each of these companies is either publicly traded or a division of a
publicly-traded company, and they enjoy several competitive advantages, including:



| |  | significantly greater name recognition;
| | - | ---------------------------------------



| |  | established relations with health care professionals, customers and third-party payors;
| | - | ---------------------------------------------------------------------------------------



| |  | additional lines of products, and the ability to offer rebates or bundle products to offer higher discounts or incentives to gain a competitive advantage; and
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | greater resources for product development, sales and marketing, and patent litigation.
| | - | --------------------------------------------------------------------------------------



These companies and others have developed and will continue to develop and acquire new products that compete directly with our products. In
addition, our competitors spend significantly greater funds for the research, development, promotion and sale of new and existing products. These resources can allow them to respond more quickly to new or emerging technologies and changes in
customer requirements. These resources also allow them to aggressively promote and discount their products, particularly system kits. For all the foregoing reasons, we may not be able to compete successfully against our current and future
competitors.



Because the medical device industry is litigious, we may be
sued for allegedly violating the intellectual property rights of others.



The medical technology industry has in the past been characterized by a substantial amount of litigation and related administrative proceedings regarding patents and intellectual property rights. In addition, major medical device companies
have used litigation against emerging growth companies as a means of gaining a competitive advantage. Medtronic, Inc., a large medical device company, has recently filed a lawsuit against Deltec, Inc., alleging that Deltecs Cozmo insulin pump
infringes certain Medtronic patents. The CozMore Insulin Technology System is a product we are developing with Deltec that permits the electronic transmission of a blood glucose reading taken using our FreeStyle blood glucose monitoring technology
to the Cozmo insulin pump. If Deltec were found to infringe the Medtronic patents, it would have to obtain a license or redesign its Cozmo insulin pump to avoid infringing Medtronics patents, which could delay the launch of the CozMore system
or possibly reduce its features.



Should third parties file patent applications
or be issued patents claiming technology also claimed by us in pending applications, we may be required to participate in interference proceedings in the U.S. Patent and Trademark Office to determine the relative priorities of our inventions and the
third parties inventions. We could also be required to participate in interference proceedings involving our issued patents and pending applications of another entity. An adverse outcome in an interference proceeding could require us to cease
using the technology or to license rights from prevailing third parties.



Third
parties may claim we are using their patented inventions and may go to court to stop us from engaging in our normal operations and activities. These lawsuits are expensive to defend and conduct and would also consume and divert the time and
attention of our management. A court may decide that we are infringing a third partys patents and may order us to cease the infringing activity. The court could also order us to pay damages for the infringement. These damages could be
substantial and could harm our business, financial condition and operating results.

##### Table of Contents

In September 2001, we received a letter from the exclusive licensee of an issued patent alleging that FreeStyle infringes
the patent and requesting that we contact the licensee regarding sublicense opportunities. We have evaluated the patent and we are discussing a possible sublicense or cross-license with the licensee. In August 2002, we received a letter from the
owner of an issued United States patent that states our FreeStyle Tracker System may infringe the patent. We are discussing a possible license or cross-license with that patent owner.



If we were unable to obtain, on reasonable commercial terms, any necessary license following a determination of infringement or an adverse
determination in litigation or in interference or other administrative proceedings, we would have to redesign our products to avoid infringing a third partys patent and could temporarily or permanently have to discontinue manufacturing and
selling some of our products. If this were to occur, it would negatively impact future sales.



If we fail to protect our intellectual property rights, our competitors may take advantage of our ideas and compete directly against us.



We rely on patent protection, as well as a combination of copyright, trade secret and trademark laws, and nondisclosure, confidentiality
agreements and other contractual restrictions to protect our proprietary technology. However, these legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep any competitive advantage. For
example, our patents may be challenged, invalidated or circumvented by third parties. Our patent applications may not be issued as patents in a form that will be advantageous to us. We may not be able to prevent the unauthorized disclosure or use of
our technical knowledge or other trade secrets by employees. Furthermore, the laws of foreign countries may not protect our intellectual property rights to the same extent as the laws of the United States. Even if our intellectual property rights
are adequately protected, litigation may be necessary to enforce our intellectual property rights, which could result in substantial costs to us and result in a substantial diversion of management attention. If our intellectual property is not
adequately protected, our competitors could use our intellectual property to enhance their products. This would harm our competitive position, decrease our market share and otherwise harm our business.



The prosecution and enforcement of patents licensed to us by third parties are not within
our control, and without these technologies, our products may not be successful and our business would be harmed.



We rely on licenses to use various technologies that are material to our business. We do not own the patents that underlie these licenses. The licenses from Asulab, SA
and Inverness Medical Innovations, Inc. grant us the right under specific patents to make and sell diagnostic devices for diabetes monitoring that contain the inventions claimed in the licensed patents. Our rights to use these technologies and
employ the inventions claimed in the licensed patents are subject to our licensors abiding by the terms of those licenses. In addition, we often do not control the prosecution of the patents to which we hold licenses or the strategy for determining
when such patents should be enforced. As a result, we are largely dependent upon our licensors to determine the appropriate strategy for prosecuting and enforcing those patents.



If we are unable to continue to develop innovative products in the glucose monitoring market, our business would be harmed.



The glucose monitoring market is subject to rapid technological change and
product innovations. Our products are based on our proprietary technology, but our competitors may succeed in developing or marketing products that will be technologically superior to ours or be more competitive with regard to product features. In
addition, over $91 billion is spent annually on the treatment of diabetes and its complications and the National Institutes for Health and other supporters of diabetes research are continually seeking ways to prevent or cure diabetes. Therefore, our
products may also be rendered obsolete by technological breakthroughs in diabetes prevention, monitoring or treatment.



We are currently developing additional enhancements for our FreeStyle products. We are also developing new products such as the CozMore Insulin Technology System, a
product we are developing with Deltec, Inc. that permits the electronic transmission of a blood glucose reading taken using our FreeStyle blood glucose monitoring technology to Deltecs Cozmo insulin pump, and Navigator, our continuous glucose
monitoring system. Marketing of these products will require FDA and other regulatory clearances and approvals. We experienced some delays in the clinical trials conducted to support the approval of Navigator due to problems with the electronics
portion of the system. Development of Navigator and other products will require additional research and development expenditures. We may not be successful in developing, marketing or manufacturing these new products.



In addition, several of our competitors are in various stages of development of products
similar to Navigator, and the FDA has approved two of these products for adjunctive use with in vitro blood glucose monitoring systems. If any of our competitors succeeds in developing a continuous glucose monitor that is approved for
marketing as a replacement for in vitro blood glucose monitoring, this would negatively affect our future revenues.

##### Table of Contents

Similarly, several of our competitors and some new market entrants are developing products that have small sample size
requirements, the ability to test on the fingertip and other body sites, or the ability to communicate with an insulin pump. Becton, Dickinson and Company, for instance, recently launched a blood glucose monitoring system that claims the same sample
size requirement as FreeStyle and communicates with an insulin pump from Medtronic, Inc., the leading provider of such pumps. The successful development and introduction of such products by competitors or new entrants would reduce the product
benefits of our FreeStyle products versus the competition and could adversely impact future revenues.



If we fail to obtain or maintain necessary FDA clearances or approvals for products, or if approvals are delayed, we will be unable to commercially distribute and market our products in the United States.



Our products are medical devices that are subject to extensive regulation
in the United States and in foreign countries where we do business. Unless an exemption applies, each medical device that we wish to market in the United States must first receive either 510(k) clearance or premarket approval from the FDA. Either
process can be lengthy and expensive. The FDAs 510(k) clearance process usually takes from four to twelve months from the date the application is complete, but may take longer. Although we have obtained 510(k) clearance for our initial
product, FreeStyle, our 510(k) clearance can be revoked if safety or effectiveness problems develop. The premarket approval process is much more costly, lengthy and uncertain. It generally takes from one to three years from the date the application
is complete or even longer. However, achieving a completed application is a process that may take numerous clinical trials and require the filing of amendments over time. Therefore, even if a product is successfully developed, it may not be
commercially available for a number of years. Navigator, our continuous glucose monitoring system under development, will require premarket approval. We experienced some delays in the clinical trials conducted to support the approval of Navigator
due to problems with the electronics portion of the system. We may not be able to obtain additional clearances or approvals for Navigator or other products in a timely fashion, or at all. Delays in obtaining clearance or approval could adversely
affect our revenues and profitability.



Modification to our marketed devices
may require new 510(k) clearances or premarket approvals. Any modification to an FDA cleared device that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires a new FDA 510(k)
clearance or possibly premarket approval. The FDA requires every manufacturer to make this determination in the first instance, but the FDA can review any such decision and potentially require us to cease marketing or recall the modified devices
until these clearances are obtained.



Any modification to an FDA cleared
device that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires a new FDA 510(k) clearance or possibly premarket approval. The FDA requires every manufacturer to make this
determination in the first instance, but the FDA can review any such decision. We have modified aspects of FreeStyle since receiving regulatory approval, but we believe that new 510(k) clearances are not required. In the case of certain labeling
changes for FreeStyle, the FDA required a new 510(k) clearance which was obtained in December 2001. We may make additional modifications to FreeStyle and future products after they have received clearance or approval, and in appropriate
circumstances, determine that new clearance or approval is unnecessary. The FDA may not agree with any of our decisions not to seek new clearance or approval. If the FDA requires us to seek 510(k) clearance or premarket approval for any
modifications to a previously cleared product, we may be required to cease marketing or recall the modified device until we obtain this clearance or approval. Also, in these circumstances, we may be subject to significant regulatory fines or
penalties.



If our suppliers or we fail to comply with the FDAs
Quality System Regulation, our manufacturing operations could be delayed, and our product sales and profitability could suffer.



Our manufacturing processes for our FreeStyle test strips, as well as the manufacturing processes utilized by our suppliers of FreeStyle meters, lancing devices, lancets
and control solution, are required to comply with the FDAs Quality System Regulation, which covers the methods and documentation of the design, testing, production, control, quality assurance, labeling, packaging, storage and shipping of our
products. The FDA enforces the Quality System Regulation through unannounced inspections. The manufacturing lines for our FreeStyle meters at Flextronics International Ltd. in China have not been inspected to date. If we or one of our suppliers fail
a Quality System Regulation inspection, our operations could be disrupted and our manufacturing delayed. If we fail to take adequate corrective action in response to any FDA observations, we could face various enforcement actions, which could
include a shut-down of our manufacturing operations and a recall of our products, which would harm our reputation and cause our product sales and profitability to suffer. Furthermore, our key component suppliers may not currently be or may not
continue to be in compliance with applicable regulatory requirements.

##### Table of Contents

Our products are subject to product recalls or field corrective actions even after receiving FDA clearance or
approval, which would harm our reputation.



The FDA and similar
governmental authorities in other countries have the authority to require the recall of or field corrective actions for our products in the event of material deficiencies or defects in design or manufacture. A government mandated or firm-initiated
recall or field corrective action by us could occur as a result of component failures, manufacturing errors or design defects. We commenced a firm-initiated field corrective action due to software bugs associated with the diabetes management
features of our FreeStyle Tracker diabetes management system shortly after its launch. Any recall of or material field corrective action for product may divert managerial and financial resources and harm our reputation with customers.



We currently depend on single-source suppliers and manufacturers for our FreeStyle
products, and the loss of any of these suppliers or manufacturers could harm our business.



Our meters, along with our lancing devices and lancets, are each currently manufactured according to our specifications by single third-party manufacturers. The meters, lancing devices and lancets are manufactured
from components purchased from outside suppliers, and some of these components are currently single-sourced. We have previously experienced delays in the delivery of some sole sourced electronic components for our meters. Our FreeStyle test strips,
which we manufacture ourselves, are comprised of several components obtained from single-source suppliers. In the event we are unable, for whatever reason, to obtain components from suppliers as scheduled, or if our contract manufacturers are unable
to meet our manufacturing requirements, we may not be able to obtain components from alternate suppliers or engage an additional manufacturer in a timely manner. Any disruption or delay in shipments of FreeStyle meters, test strips, lancing devices
or lancets could result in the loss of customers or the failure to acquire new customers, if they choose a competitors product because our product is not available. Such a disruption or delay would negatively affect our revenues. In addition,
the purchase of components from alternate suppliers or engaging an additional manufacturer in a timely manner could impose increased costs that could negatively impact our gross margins.



If we are unable to meet customer demand, it would adversely impact our financial results and restrict our sales growth.



To be successful, we must manufacture our FreeStyle test strips in substantial quantities
at acceptable costs. If we do not succeed in manufacturing sufficient quantities of our test strips to meet customer demand, we could lose customers and fail to acquire new customers, if they choose a competitors product because our product is
not available. Increasing demand since the launch of FreeStyle has necessitated an increase in our test strip manufacturing capacity. In response, we have expanded our manufacturing capacity at our facilities in Alameda, California. If we are unable
to meet customer demand for FreeStyle test strips, it would adversely affect our financial results and restrict our sales growth.



We are subject to additional risks associated with international operations.



We believe that a significant amount of our future revenues may come from international sales, and these sales are subject to a number of
risks. These risks include:



| |  | foreign regulatory requirements different from those in the United States, which may require product or labeling changes;
| | - | -------------------------------------------------------------------------------------------------------------------------



| |  | fluctuations in exchange rates of the U.S. dollar against foreign currencies, which may affect demand for our products overseas;
| | - | --------------------------------------------------------------------------------------------------------------------------------



| |  | export license requirements, the imposition of governmental controls, political and economic instability, trade restrictions, changes in tariffs and difficulties in staffing and
managing international operations, any of which could adversely affect our international sales; and
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | parallel importing by third parties, which supplants our product sales in certain higher-margin markets. Parallel importing occurs when we ship product to a foreign market for sale
to end users in that market and a third party reships the product to another foreign market where it can sell our products at a higher-margin than the designated market.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We outsource several key parts of our operations and any interruption in the services provided could prevent us from expanding our
business.



We currently outsource several aspects of our business,
including the manufacture of our meters, lancing devices and lancets, the functioning of our procurement systems, the operation of our customer service function, and certain distribution and logistics functions. Since outsourcing leaves us without
direct control over these business functions, interruptions in the services of our third-party providers may be difficult or impossible to remedy in a timely fashion. In addition, we may be unable to obtain the necessary resources from our
third-party providers to meet realized growth in our business.

Significant product returns could harm our operating results.



Our return policy allows end users in the United States and Canada to return our system kits
to us for any reason for a full refund within 30 days of purchase. In addition, our system kits and test strips currently have an 18 month shelf life. Retailers and wholesalers in the United States and Canada can return these products to us in
accordance with our returned goods policy within six months after this expiration date. We have established reserves for the liability associated with product returns. However, unforeseen returns from retailers, wholesalers or end users could
adversely affect our operating results.



We may have warranty claims that
exceed our reserves.



Our meters carry a five-year warranty against defects
in materials and workmanship. We have established reserves for the liability associated with product warranties. However, any unforeseen warranty exposure could adversely affect our operating results.



If we choose to acquire new and complementary businesses, products or technologies instead
of developing them ourselves, we may be unable to complete these acquisitions or to successfully integrate an acquired business or technology in a cost-effective and non-disruptive manner.



Our success depends on our ability to continually enhance and broaden our product offerings
in response to changing technologies, customer demands and competitive pressures. Accordingly, we may, in the future, acquire complementary businesses, products, or technologies instead of developing them ourselves. We do not know if we will be able
to complete any acquisitions, or whether we will be able to successfully integrate any acquired business, operate it profitably or retain its key employees. Integrating any business, product or technology we acquire could be expensive and time
consuming, disrupt our ongoing business and distract our management. If we are unable to integrate any acquired entities, products or technologies effectively, our business will suffer. In addition, any amortization of goodwill or other assets or
charges resulting from the costs of acquisitions could harm our business and operating results.



If we require future capital, we may not be able to secure additional funding in order to expand our operations and develop or acquire new products.



We may seek additional funds from public and private stock offerings, borrowings under lease lines of credit or other sources. This
additional financing may not be available on a timely basis on terms acceptable to us, or at all. This financing may be dilutive to stockholders or may require us to grant a lender a security interest in our assets. The amount of money we will need
will depend on many factors, including:



| |  | revenues generated by sales of FreeStyle and our future products;
| | - | -----------------------------------------------------------------



| |  | expenses we incur in developing and selling our products;
| | - | ---------------------------------------------------------



| |  | the commercial success of our research and development efforts; and
| | - | -------------------------------------------------------------------



| |  | the emergence of competing or complementary technological developments.
| | - | -----------------------------------------------------------------------



If adequate funds are not available, we may have to delay development or commercialization of our products, defer the acquisition of complementary products or license to
third parties the rights to commercialize products or technologies that we would otherwise seek to commercialize. We also may have to reduce marketing, customer support or other resources devoted to our products. Any of these results could harm our
financial condition.



We may have difficulty managing our growth.



We have experienced significant growth in the scope of our operations and
the number of our employees. We expect this growth to continue though at reduced rates. This growth may continue to place a significant strain on our management and operations. Our ability to manage this growth will depend upon our ability to
attract, hire and retain skilled employees. Our success will also depend on the ability of our officers and key employees to continue to implement and improve our operational and other systems, to manage multiple, concurrent development projects and
to hire, train and manage our employees. Our future success is heavily dependent upon growth and acceptance of new products. If we cannot scale our business appropriately or otherwise adapt to anticipated growth and new product introduction, our
business, financial condition and results of operations will be adversely affected.

Our success will depend on our ability to attract and retain key personnel and scientific staff.



We believe our future success will depend upon our ability to successfully manage our growth,
including attracting and retaining scientists, engineers and other highly skilled personnel. Our employees may terminate their employment with us at any time and are not generally subject to employment contracts. Hiring qualified management and
technical personnel will be difficult due to the limited number of qualified professionals. Competition for these types of employees is intense in the field of diabetes monitoring and management. We have in the past experienced difficulty in
recruiting qualified personnel. If we fail to attract and retain personnel, particularly management and technical personnel, we may not be able to execute on our business plan.



If we do not provide quality customer service, we would lose customers and our operating results would suffer.



Our ability to provide quality customer service to our customers, health care professionals
and educators is critical. To effectively compete, we must build strong brand awareness among our customers, much of which is based upon personal referrals. In order to gain these referrals, we must provide customer service representatives who are
able and available to provide our customers with answers to questions regarding our products. This will require us to continue to build and maintain customer service operations, for which we currently rely on a single third-party provider. We will
require increased staff at our third-party provider to further support growth in new customers. Any failures or disruption to our customer services operations, or the termination of our contract with our only third-party provider, could cause us to
lose customers.



Complying with international regulatory requirements is an
expensive, time-consuming process and approval is never certain.



International sales of our products are subject to strict regulatory requirements. The review process varies from country to country, is typically lengthy and expensive, and approval is never certain. We have the required regulatory
approvals to market FreeStyle in various countries outside the United States. Failure to maintain current foreign approvals or to receive and maintain approvals in other countries would prevent us from expanding international sales of FreeStyle,
which would negatively impact our future revenues.



Our meters are
manufactured in China, and we are subject to risks of international manufacturing operations and risks associated with SARS.



Our FreeStyle meters are manufactured according to our specifications by a single third-party manufacturer at its facility in China. The geographical distance between our
principal facility in Alameda, California and the manufacturing facility in China creates a number of logistical and communications challenges. These challenges include managing operations across multiple time zones, directing the manufacture and
delivery of products across distances, coordinating procurement and delivery of components and raw materials and coordinating the activities and decisions of the core manufacturing team, which is based in China and California.



Governmental authorities in China exercise significant influence over many aspects of the
economy, and their actions could have a significant effect on the manufacture of our Freestyle meters. Risks of changes in economic and political conditions in China, include:



| |  | labor unrest and difficulties in staffing;
| | - | ------------------------------------------



| |  | increases in duties and taxation levied on our Freestyle meters;
| | - | ----------------------------------------------------------------



| |  | limitations on imports of Freestyle meter components or exports of assembled Freestyle meters, or other travel restrictions;
| | - | ----------------------------------------------------------------------------------------------------------------------------



| |  | expropriation of private enterprises;
| | - | -------------------------------------



| |  | a potential reversal of current favorable policies encouraging foreign trade; and
| | - | ---------------------------------------------------------------------------------



| |  | fluctuations in the value of local currency.
| | - | --------------------------------------------



In addition, the recent outbreak of severe acute respiratory syndrome (SARS) may adversely impact our business and particularly Flextronics Freestyle meter
manufacturing operations. The SARS outbreak has been most notable in Asia, in particular China. Flextronics manufacture of our Freestyle meters in China could suffer if its employees contract SARS or otherwise are unable to fulfill their
responsibilities. In addition, our business could also be harmed if travel to or from China and the United States is restricted or inadvisable.

Any delay or disruption in the manufacture of our Freestyle meters, including delays or disruptions relating to these
logistical and communication challenges, changes in the economic or political conditions in China or the recent outbreak of SARS, could delay or disrupt shipments of Freestyle meters to our customers. Shipment delays or disruptions could result in
the loss of customers or the failure to acquire new customers, if they choose a competitors product because our product is not available. Such a disruption or delay would negatively affect our revenues. In addition, engaging an additional
manufacturer or commencing Freestyle meter manufacturing obligations on an alternative line in a timely manner could impose increased costs that would negatively impact our gross margins.



If we become subject to product liability claims, we may be required to pay damages that exceed our insurance coverage.



Our business exposes us to potential product liability claims that are inherent in the
testing, production, marketing and sale of human diagnostic products. While we believe that we are reasonably insured against these risks, we may not be able to obtain insurance in amounts or scope sufficient to provide us with adequate coverage
against all potential liabilities. Currently, we maintain product liability insurance in the amount of $22.0 million. A product liability claim in excess of our insurance coverage would have to be paid out of cash reserves and would harm our
reputation in the industry.



Most of our operations are currently conducted
at a single location, and a disaster at this facility is possible and could result in a prolonged interruption of our business.



We currently conduct all our scientific and test strip manufacturing and most of our management activities at a single location in Alameda, California near known
earthquake fault zones. In addition, our facilities were built on fill material dredged from the San Francisco Bay in the 1960s. We have taken precautions to safeguard our facilities, including insurance, health and safety protocols, and off-site
storage of computer data. However, a natural disaster, such as an earthquake, fire or flood, could cause substantial delays in our operations, damage or destroy our manufacturing equipment or inventory, and cause us to incur additional expenses. A
disaster could seriously harm our business and adversely affect our reputation with customers. The insurance we maintain against fires, floods, and earthquakes may not be adequate to cover our losses in any particular case.



We may be liable for contamination or other harm caused by materials that we use, and
changes in environmental regulations could cause us to incur additional expense.



Our research and development and clinical processes involve the use of potentially harmful biological materials as well as hazardous materials. We are subject to federal, state and local laws and regulations governing the use, handling,
storage and disposal of hazardous and biological materials and we incur expenses relating to compliance with these laws and regulations. If violations of environmental, health, and safety laws occur, we could be held liable for damages, penalties
and costs of remedial actions. These expenses or this liability could have a significant negative impact on our financial condition. We may violate environmental, health and safety laws in the future as a result of human error, equipment failure, or
other causes. Environmental laws could become more stringent over time, imposing greater compliance costs and increasing risks and penalties associated with violations. We are subject to potentially conflicting and changing regulatory agendas of
political, business, and environmental groups. Changes to or restrictions on permitting requirements or processes, hazardous or biological material storage or handling might require an unplanned capital investment and/or relocation. Compliance with
new laws or regulations could harm our business, financial condition and results of operations.



Our common stock has been and will likely continue to be subject to substantial price and volume fluctuations, and the value of our stock could decline.



The market prices and trading volumes for emerging growth medical device companies and our
company in particular have been highly volatile and are likely to continue to be highly volatile in the future. The following factors, in addition to other risk factors described in this section, may have a significant impact on the market price of
our stock:



| |  | volume and timing of orders for our products;
| | - | ---------------------------------------------



| |  | monthly variations in market data relative to our competitors;
| | - | --------------------------------------------------------------



| |  | our ability to develop, obtain regulatory clearance for, and market, new and enhanced products on a timely basis;
| | - | -----------------------------------------------------------------------------------------------------------------



| |  | the announcement of new products or product enhancements by us or our competitors;
| | - | ----------------------------------------------------------------------------------



| |  | announcements of technological or medical innovations in the monitoring or treatment of diabetes;
| | - | -------------------------------------------------------------------------------------------------



| |  | product liability claims or other litigation;

The sales of a substantial number of shares of our common stock may adversely affect the
market price for our common stock



Sales of a significant number of shares
of our common stock in the public market or the market perception that these sales may occur, could negatively affect the market price for our common stock. As of November 1, 2003, we had 41,617,078 shares of common stock outstanding. All of these
shares are available for sale. Also, many of our employees, consultants and directors may exercise their stock options in order to sell the stock underlying their options in the market under a registration statement we have filed with the SEC.



Our executive officers and directors and entities affiliated with them own
a significant percentage of our stock, and as a result, the trading price for our shares may be depressed and these stockholders can take actions that may be adverse to investors interests.



Our executive officers and directors and entities affiliated with them beneficially own, in
the aggregate, approximately 18% of our common stock as of November 1, 2003. This significant concentration of share ownership may adversely affect the trading price for our common stock because investors often perceive disadvantages in owning stock
in companies with concentrated ownership. These stockholders, acting together, will have the ability to exert substantial influence over all matters requiring approval by our stockholders, including the election and removal of directors and any
proposed merger, consolidation or sale of all or substantially all of our assets. In addition, they could dictate the management of our business and affairs. This concentration of ownership could have the effect of delaying, deferring or preventing
a change in control, or impeding a merger or consolidation, takeover or other business combination that could be favorable to our investors.



Our Stockholder Rights Plan, charter documents and Delaware law may inhibit a takeover that stockholders consider favorable and could also limit the market price of
investors stock.



In February 2003, our Board of Directors adopted a
Stockholder Rights Plan. The Stockholder Rights Plan provides for a dividend distribution of one Preferred Shares Purchase Right on each outstanding share of our common stock. Each Right entitles stockholders to buy 1/1000th of a share of the
companys Series A participating preferred stock at an exercise price of $100.00. The Rights will become exercisable after a person or group announces the acquisition of 15% or more of our common stock, or announces commencement of a tender
offer, the consummation of which would result in ownership by the person or group of 15% or more of our common stock. We will be entitled to redeem the Rights at $0.001 per Right at any time on or before the tenth day following acquisition by a
person or group of 15% or more of our common stock. The Stockholder Rights Plan could have the effect of delaying, deferring or preventing a change in control of TheraSense, including without limitation, discouraging a proxy contest or making more
difficult the acquisition of a substantial block of our common stock



Our
certificate of incorporation and bylaws contain provisions that could also delay or prevent a change in control of our company. Among these provisions are the following:



| |  | authorize the issuance of preferred stock which can be created and issued by the board of directors without prior stockholder approval, commonly referred to as blank
check preferred stock, with rights senior to those of common stock;
| | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | prohibit stockholder actions by written consent; and
| | - | ----------------------------------------------------



| |  | provide for a classified board of directors.
| | - | --------------------------------------------



In addition, we are governed by the provisions of Section 203 of Delaware General Corporate Law. These provisions may prohibit stockholders owning 15% or more of our
outstanding voting stock from merging or combining with us. Section 203 of Delaware General Corporate Law, our Stockholder Rights Plan and other provisions in our amended and restated certificate of incorporation and bylaws and under Delaware law
could reduce the price that investors might be willing to pay for shares of our common stock in the future and result in the market price being lower than it would be without these provisions.

The liquidity of our common stock is uncertain since it has been publicly traded for a short period of time and may
have a limited market.



Prior to our initial public offering in October
2001, there was no public market for our common stock. We cannot predict the extent to which investor interest in our company will lead to the development of an active, liquid trading market. Active trading markets generally result in lower price
volatility and more efficient execution of buy and sell orders for investors.



ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK



Because we translate foreign currencies into United States dollars for reporting purposes, exchange rates can have an impact on our financial results, although this impact is generally immaterial. We believe that our
exposure to currency exchange risk is low because our Canadian and United Kingdom subsidiaries satisfy their financial obligations almost exclusively in their local currencies. As of September 30, 2003, we did not engage in foreign currency hedging
activities.



The primary objective of our investment activities is to preserve
principal while at the same time maximizing the income we receive from our invested cash without significantly increasing risk of loss. As of September 30, 2003, our cash, cash equivalents and available-for-sale securities consisted primarily of
money market funds maintained at three major U.S. financial institutions. The recorded carrying amounts of cash and cash equivalents approximate fair value due to their short-term maturities. We do not believe that an increase in market rates would
have any significant negative impact on the realized value of our investments, but an increase in market rates could negatively impact the interest expense associated with a portion of our long-term debt. Substantially all of our long-term debt
obligations have a fixed rate of interest.



ITEM 4. CONTROLS AND PROCEDURES



| | (a) | Evaluation of disclosure controls and procedures. Our chief executive officer and our chief financial officer, after evaluating the effectiveness of our disclosure
controls and procedures (as defined in the Securities Exchange Act of 1934 Rules 13a-15(e) or 15d-15(e)) as of the end of the period covered by this report, have concluded that as of the end of the period covered by this report, our disclosure
controls and procedures were adequate and designed to ensure that material information relating to us and our consolidated subsidiaries would be made known to them by others within those entities.
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (b) | Changes in internal controls over financial reporting. There were no changes in our internal controls over financial reporting identified in connection with the evaluation
required by paragraph (d) of Exchange Act Rule 13a-15 or 15d-15 that occurred during the quarter ended September 30, 2003 or to our knowledge, in other factors that have materially affected or are reasonably likely to materially affect our internal
controls over financial reporting.

PART II: OTHER INFORMATION



ITEM 1. LEGAL PROCEEDINGS



We are not
currently a party to any material pending legal proceedings.



ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS



In October 2001, we closed our initial public offering of 6,900,000 shares of our common stock at a per share price of $19.00 pursuant to a Registration Statement on Form S-1 (Registration No. 333-64456), which was declared effective on
October 11, 2001.



To date, we have spent a portion of the net proceeds as
follows (i) approximately $11.9 million for the purchase of capital equipment, (ii) approximately $3.6 million to expand our facility in Alameda, California, (iii) approximately $27.0 million to sponsor free product samples and accelerate the hiring
of additional sales representatives, (iv) approximately $5.9 million for research and development of enhanced FreeStyle products and our Continuous Glucose Monitoring System and (v) approximately $18.1 million for general working capital purposes.
We are currently investing the remaining net proceeds from the offering for future use as additional working capital. Such remaining net proceeds have been invested in highly liquid instruments, such as commercial paper and U.S. Government
obligations, with an average maturity of twelve months or less.



From January
1, 2003 through September 30, 2003, we did not issue any unregistered securities.
