NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1. Nature of the Business

     Insulet Corporation (the “Company”) is principally engaged in the development, manufacture and marketing of an insulin infusion system for people with insulin-dependent diabetes. The Company was incorporated in Delaware in 2000 and has its corporate headquarters in Bedford, Massachusetts. Since inception, the Company has devoted substantially all of its efforts to designing, developing, manufacturing and marketing the OmniPod Insulin Management System (“OmniPod”), which consists of the OmniPod disposable insulin infusion device and the handheld, wireless Personal Diabetes Manager (“PDM”). The Company commercially launched the OmniPod Insulin Management System in August 2005 after receiving FDA 510(k) approval in January 2005. The first commercial product was shipped in October 2005.

     In January 2010, the Company entered into a five year distribution agreement with Ypsomed Distribution AG, or Ypsomed, to become the exclusive distributor of the OmniPod System in eleven countries. Through the Company’s partnership with Ypsomed, the OmniPod System is now available in seven markets, namely Germany, the United Kingdom, France, the Netherlands, Sweden, Norway, and Switzerland. The Company expects that Ypsomed will begin distribution of the OmniPod System, subject to approved reimbursement, in the other markets under the agreement in the last half of 2011 or 2012. In February 2011, the Company entered into a distribution agreement with GlaxoSmithKline Inc., or GSK, to become the exclusive distributor of the OmniPod System in Canada. The Company expects that GSK will begin distributing the OmniPod System, subject to approved reimbursement, in the second quarter of 2011.

2. Summary of Significant Accounting Policies

Basis of Presentation

     The unaudited consolidated financial statements in this Quarterly Report on Form 10-Q have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three month period ended March 31, 2011, are not necessarily indicative of the results that may be expected for the full year ending December 31, 2011, or for any other subsequent interim period.

     The unaudited consolidated financial statements in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010.

Use of Estimates in Preparation of Financial Statements

     The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting periods. The most significant estimates used in these financial statements include the valuation of inventories, accounts receivable and equity instruments, the lives of property and equipment, as well as warranty reserves and allowance for doubtful accounts calculations. Actual results may differ from those estimates.

Principles of Consolidation

     The unaudited consolidated financial statements in this Quarterly Report on Form 10-Q include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.

Accounts Receivable and Allowance for Doubtful Accounts

     Accounts receivable consist of amounts due from third-party payors, patients and third-party distributors. The allowance for doubtful accounts is recorded in the period in which revenue is recorded or at the time potential collection risk is identified. The Company estimates its allowance based on historical experience, assessment of specific risk, discussions with individual customers and various assumptions and estimates that are believed to be reasonable under the circumstances.

Inventories

     Inventories are held at the lower of cost or market, determined under the first-in, first-out (“FIFO”) method. Inventory has been recorded at cost as of March 31, 2011 and December 31, 2010. Work in process is calculated based upon a build up in the stage of completion using estimated labor inputs for each stage in production. Costs for PDMs and OmniPods include raw material, labor and manufacturing overhead. The Company periodically reviews inventories for potential impairment based on quantities on hand and expectations of future use.

Property and Equipment

     Property and equipment is stated at cost and depreciated using the straight-line method over the estimated useful lives of the respective assets. Leasehold improvements are amortized over their useful life or the life of the lease, whichever is shorter. Assets capitalized under capital leases are amortized in accordance with the respective class of owned assets and the amortization is included with depreciation expense. Maintenance and repair costs are expensed as incurred.

Warranty

     The Company provides a four year warranty on its PDMs and may replace any OmniPods that do not function in accordance with product specifications. The Company estimates its warranty reserves at the time the product is shipped based on historical experience and the estimated cost to service the claims. Cost to service the claims reflects the current product cost, which has been decreasing over time. As these estimates are based on historical experience, and the Company continues to introduce new versions of existing products, the Company also considers the anticipated performance of the product over its warranty period in estimating warranty reserves.

Revenue Recognition

     The Company generates nearly all of its revenue from sales of its OmniPod Insulin Management System to diabetes patients and third-party distributors who resell the product to diabetes patients. The initial sale to a new customer or third-party distributor typically includes OmniPods and a Starter Kit, which includes the PDM, the OmniPod System User Guide and the OmniPod System Interactive Training CD. Subsequent sales to existing customers typically consist of additional OmniPods.

     Revenue recognition requires that persuasive evidence of a sales arrangement exists, delivery of goods occurs through transfer of title and risk and rewards of ownership, the selling price is fixed or determinable and collectability is reasonably assured. With respect to these criteria:

	•		The evidence of an arrangement generally consists of a physician order form, a patient information form, and if applicable, third-party insurance approval for sales directly to patients or a purchase order for sales to a third-party distributor.
	•		Transfer of title and risk and rewards of ownership are passed to the patient or third-party distributor upon shipment of the products.
	•		The selling prices for all sales are fixed and agreed with the patient or third-party distributor, and, if applicable, the patient’s third-party insurance provider(s), prior to shipment and are based on established list prices or, in the case of certain third-party insurers, contractually agreed upon prices. Provisions for discounts and rebates to customers are established as a reduction to revenue in the same period the related sales are recorded.

     The Company assesses whether different elements qualify for separate accounting. The Company recognizes revenue for the initial shipment to a patient or other third party once all elements have been delivered.

     The Company offers a 45-day right of return for its Starter Kits sales, and defers revenue to reflect estimated sales returns in the same period that the related product sales are recorded. Returns are estimated through a comparison of the Company’s historical return data to their related sales. Historical rates of return are adjusted for known or expected changes in the marketplace when appropriate. When doubt exists about reasonable assuredness of collectability from specific customers, the Company defers revenue from sales of products to those customers until payment is received.

     In March 2008, the Company received a cash payment from Abbott Diabetes Care, Inc. (“Abbott”) for an agreement fee in connection with execution of the first amendment to the development and license agreement between the Company and Abbott. The Company recognizes revenue on the agreement fee from Abbott over the initial five year term of the agreement, and the non-current portion of the agreement fee is included in other long-term liabilities. Under the amended Abbott agreement, beginning July 1, 2008, Abbott agreed to pay an amount to the Company for services performed in connection with each sale of a PDM that includes an Abbott Discrete Blood Glucose Monitor to certain customers. In July 2010, the Company entered into a second amendment to the development and license agreement with Abbott. Under the terms of the second amendment, Abbott agreed to pay certain amounts to the Company for services performed in connection with each sale of a PDM that includes an Abbott Discrete Blood Glucose Monitor to customers in certain additional territories. The Company recognizes revenue related to this portion of the Abbott agreement at the time it meets the criteria for revenue recognition, typically at the time the revenue is recognized on the sale of the PDM to the patient. In the three month periods ended March 31, 2011 and 2010, the Company recognized revenue related to the amended Abbott agreement of $1.2 million and $1.1 million, respectively. There was no impact to cost of revenue related to this agreement.

     The Company had deferred revenue of $2.3 million and $4.8 million as of March 31, 2011 and December 31, 2010, respectively. The deferred revenue recorded as of March 31, 2011 was comprised of product-related revenue as well as the non-amortized agreement fee related to the Abbott agreement.

Concentration of Credit Risk

     Financial instruments that subject the Company to credit risk primarily consist of cash, cash equivalents and accounts receivable. The Company maintains the majority of its cash with two accredited financial institutions. Although revenue is recognized from shipments directly to patients or third-party distributors, the majority of shipments are billed to third-party insurance payors. There were no third-party payors that accounted for more than 10% of gross accounts receivable as of March 31, 2011 or December 31, 2010.

Segment Reporting

     Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated on a regular basis by the chief operating decision-maker, or decision-making group, in deciding how to allocate resources to an individual segment and in assessing performance of the segment. In light of the Company’s current product offering, and other considerations, management has determined that the primary form of internal reporting is aligned with the offering of the OmniPod System. Therefore, the Company believes that it operates in one segment.

Income Taxes

     FASB Accounting Standard Codification, or ASC 740-10, Income Taxes, clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements. FASB ASC 740-10 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. In addition, FASB ASC 740-10 provides guidance on derecogniton, classification, interest and penalties, accounting in interim periods, and disclosure and transition.

     The Company has accumulated significant losses since its inception in 2000. Since the net operating losses may potentially be utilized in future years to reduce taxable income (subject to any applicable limitations), all of the Company’s tax years remain open to examination by the major taxing jurisdictions to which the Company is subject.

     The Company recognizes estimated interest and penalties for uncertain tax positions in income tax expense. As of March 31, 2011, interest and penalties are immaterial to the consolidated financial statements.

Stock-Based Compensation

     The Company accounts for stock-based compensation under the provisions of FASB ASC 718-10, Compensation — Stock Compensation. FASB ASC 718-10 requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values.

     Nonpublic companies that used the minimum value method for either recognition or pro forma disclosures were required to apply the fair value method under FASB ASC 718-10 using the prospective-transition method. As such, the Company will continue to apply the minimum value method in future periods to equity awards outstanding that were originally measured using the minimum value method.

     The Company uses the Black-Scholes option pricing model to determine the weighted average fair value of options granted. The Company recognizes the compensation expense of share-based awards on a straight-line basis over the vesting period of the award.

     The determination of the fair value of share-based payment awards utilizing the Black-Scholes model is affected by the stock price and a number of assumptions, including expected volatility, expected life, risk-free interest rate and expected dividends. The expected life of the awards is estimated based on the “SEC Shortcut Approach” as defined in SAB 107, which is the midpoint between the vesting date and the end of the contractual term. The risk-free interest rate assumption is based on observed interest rates appropriate for the terms of the awards. The dividend yield assumption is based on company history and expectation of paying no dividends. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock-based compensation expense recognized in the financial statements is based on awards that are ultimately expected to vest. The Company evaluates the assumptions used to value the awards on a quarterly basis and if factors change and different assumptions are utilized, stock-based compensation expense may differ significantly from what has been recorded in the past. If there are any modifications or cancellations of the underlying unvested securities, the Company may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense.

     Prior to April 1, 2006, the exercise prices for options granted were set by the Company’s board of directors based upon guidance set forth by the American Institute of Certified Public Accountants. The board considered a number of factors in determining the option price, including the following factors: (1) prices for the Company’s preferred stock, which the Company had sold to outside investors in arm’s-length transactions, and the rights, preferences and privileges of the Company’s preferred stock and common stock in the Series A through Series E financings, (2) obtaining FDA 510(k) clearance, (3) launching the OmniPod System and (4) achievement of budgeted revenue and results.

     The Company retrospectively estimated the fair value of its common stock based upon several factors, including the following factors: (1) operating and financial performance, (2) progress and milestones attained in the business, (3) past sales of convertible preferred stock, (4) the results of the retrospective independent valuations and (5) the expected valuation obtained in an initial public offering. The Company believes this to have been a reasonable methodology based on the factors above and based on several arm’s-length transactions involving the Company’s stock supportive of the results produced by this valuation methodology.

     See Note 9 for a summary of the stock option activity under our stock-based employee compensation plan.

3. Long Term Debt

Convertible Notes

     In June 2008, the Company sold $85.0 million principal amount of 5.375% Convertible Senior Notes due June 15, 2013 (the “5.375% Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The interest rate on the notes is 5.375% per annum on the principal amount from June 16, 2008, payable semi-annually in arrears in cash on December 15 and June 15 of each year. The 5.375% Notes are convertible into the Company’s common stock at an initial conversion rate of

46.8467 shares of common stock per $1,000 principal amount of the 5.375% Notes, which is equivalent to a conversion price of approximately $21.35 per share, representing a conversion premium of 34% to the last reported sale price of the Company’s common stock on the NASDAQ Global Market on June 10, 2008, subject to adjustment under certain circumstances, at any time beginning on March 15, 2013 or under certain other circumstances and prior to the close of business on the business day immediately preceding the final maturity date of the notes. The 5.375% Notes will be convertible for cash up to their principal amount and shares of the Company’s common stock for the remainder of the conversion value in excess of the principal amount. The Company does not have the right to redeem any of the 5.375% Notes prior to maturity. If a fundamental change, as defined in the Indenture for the 5.375% Notes, occurs at any time prior to maturity, holders of the 5.375% Notes may require the Company to repurchase their notes in whole or in part for cash equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, including any additional interest, to, but excluding, the date of repurchase. If a holder elects to convert its 5.375% Notes upon the occurrence of a make-whole fundamental change, as defined in the Indenture for the 5.375% Notes, the holder may be entitled to receive an additional number of shares of common stock on the conversion date. These additional shares are intended to compensate the holders for the loss of the time value of the conversion option and are set forth in the Indenture to the 5.375% Notes. In no event will the number of shares issuable upon conversion of a note exceed 62.7746 per $1,000 principal amount (subject to adjustment as described in the Indenture for the 5.375% Notes).

     The Company recorded a debt discount of $26.9 million to equity to reflect the value of its nonconvertible debt borrowing rate of 14.5% per annum. This debt discount is being amortized as interest expense over the five year term of the 5.375% Notes.

     The Company incurred deferred financing costs related to this offering of approximately $3.5 million, of which $1.1 million has been reclassified as an offset to the value of the amount allocated to equity. The remainder is recorded as other assets in the consolidated balance sheet and is being amortized as a component of interest expense over the five year term of the 5.375% Notes. The Company incurred interest expense related to the 5.375% Notes of approximately $2.7 million for the three months ended March 31, 2011, of which approximately $1.6 million relates to amortization of the debt discount and deferred financing costs and $1.1 million relates to cash interest. For the three months ended March 31, 2010, the Company incurred interest expense related to the 5.375% Notes of approximately $2.5 million, of which approximately $1.4 million relates to amortization of the debt discount and deferred financing costs and $1.1 million relates to cash interest.

     As of March 31, 2011, the outstanding amounts related to the 5.375% Notes of $70.9 million are included in long-term debt in the consolidated balance sheet and reflect the debt discount of $14.1 million. As of December 31, 2010, the outstanding amounts related to the 5.375% Notes of $69.4 million are included in long-term debt and reflect the debt discount of $15.6 million. The debt discount includes the equity allocation of $25.8 million (which represents $26.9 million less the $1.1 million of allocated financing costs) offset by the accretion of the debt discount through interest expense from the issuance date over the five year term of the notes. The Company recorded $1.4 million and $1.2 million of interest expense related to the debt discount in the three months ended March 31, 2011 and 2010, respectively. As of March 31, 2011, the 5.375% Notes have a remaining term of 2.25 years.

     The Company received net proceeds of approximately $81.5 million from this offering. Approximately $23.2 million of the proceeds from this offering was used to repay and terminate the Company’s then-existing term loan, including outstanding principal and accrued and unpaid interest of $21.8 million, a prepayment fee related to the term loan of approximately $0.4 million and a termination fee of $0.9 million. In connection with this term loan, the Company issued warrants to the lenders to purchase up to 247,252 shares of Series E preferred stock at a purchase price of $3.64 per share. The warrants automatically converted into warrants to purchase common stock on a 1-for-2.6267 basis at a purchase price of $9.56 per share at the closing of the Company’s initial public offering in May 2007. As of March 31, 2011, warrants to purchase 62,752 shares of common stock remain outstanding and exercisable at a price of $9.56 per share and expire on December 27, 2013.

Facility Agreement and Common Stock Warrants

     In March 2009, the Company entered into a Facility Agreement with certain institutional accredited investors, pursuant to which the investors agreed to loan the Company up to $60 million, subject to the terms and conditions set forth in the Facility Agreement. Total financing costs, including the transaction fee, were $3.0 million and were amortized as interest expense over the 42 months of the Facility Agreement.

     In connection with the execution of the Facility Agreement, the Company issued to the lenders fully exercisable warrants to purchase an aggregate of 3.75 million shares of common stock of the Company at an exercise price of $3.13 per share. The warrants qualified for permanent treatment as equity, and their relative fair value of $6.1 million on the issuance date was recorded as additional paid-in capital and debt discount. The debt discount was amortized as non-cash interest expense over the term of the loan.

     In September 2009, the Company entered into an Amendment to the Facility Agreement whereby the Company repaid the $27.5 million originally drawn and promptly drew down the remaining $32.5 million available under the Facility Agreement. The annual interest rate was 8.5%, payable quarterly in arrears. In connection with the Amendment to the Facility Agreement, the Company entered into a Securities Purchase Agreement with the lenders whereby the Company sold 2,855,659 shares of its common stock to the lenders at $9.63 per share, a $1.9 million discount based on the closing price of the Company’s common stock of $10.28 on that date. The Company recorded the $1.9 million as a debt discount which was amortized as interest expense over the remaining term of the loan. The Company received aggregate proceeds of $27.5 million in connection with the sale of its shares. All principal amounts outstanding under the Facility Agreement were payable in September 2012.

     In June 2010, the Company entered into a Second Amendment to its Facility Agreement whereby the Company paid a $0.5 million amendment fee in exchange for the reduction of the prepayment penalties and the modification of certain other terms of the Agreement. The fee was recorded as additional debt discount and was amortized as interest expense over the remaining term of the loan.

     In December 2010, the Company paid $33.3 million to the lenders, of which $32.5 million related to principal and $0.8 million related to interest and prepayment fees, to extinguish this debt. The Company recorded a non-cash interest charge of $7.0 million in the fourth quarter of 2010 related to the write-off of the remaining debt discounts and financing costs included in other assets which were being amortized to interest expense over the term of the debt.

     In the three months ended March 31, 2010, the Company recorded cash interest related to the Facility Agreement of approximately $0.7 million and non-cash interest of approximately $0.6 million. Non-cash interest in the three months ended March 31, 2010 consists of amortization of the debt discount from the issuance of warrants and transaction fee in March 2009, amortization of the discount on the shares sold in connection with the amendment in September 2009, and amortization of the issuance costs associated with the debt. No interest related to the Facility Agreement was recorded in the three months ended March 31, 2011 as the debt was repaid in December 2010.

     As of March 31, 2011, all warrants to acquire 3.75 million shares of the Company’s common stock issued in connection with the Facility Agreement were exercised.

4. Net Loss Per Share

     Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding for the period, excluding unvested restricted common shares. Diluted net loss per share is computed using the weighted average number of common shares outstanding and, when dilutive, potential common share equivalents from options and warrants (using the treasury-stock method), and potential common shares from convertible securities (using the if-converted method). Because the Company reported a net loss for the three months ended March 31, 2011 and 2010, all potential common shares have been excluded from the computation of the diluted net loss per share for all periods presented, as the effect would have been anti-dilutive. Such potentially dilutive common share equivalents consist of the following:

		Three Months Ended
		March 31,
		2011				2010
Convertible notes			3,981,969				3,981,969
Unvested restricted common shares			—				1,776
Unvested restricted stock units			591,677				305,999
Outstanding options			3,087,641				3,505,216
Outstanding warrants			62,752				3,812,752
Total			7,724,039				11,607,712

The Company produces certain sub-assemblies for the OmniPod and maintains packaging operations in its facility in Bedford, Massachusetts. The Company purchases complete OmniPods from Flextronics. Inventories of finished goods were held at cost at March 31, 2011 and December 31, 2010.

7. Product Warranty Costs

     The Company provides a four year warranty on its PDMs and may replace any OmniPods that do not function in accordance with product specifications. Warranty expense is estimated and recorded in the period that shipment occurs. The expense is based on the Company’s historical experience and the estimated cost to service the claims. A reconciliation of the changes in the Company’s product warranty liability is as follows:

8. Commitments and Contingencies

Operating Leases

     The Company leases its facilities, which are accounted for as operating leases. The leases generally provide for a base rent plus real estate taxes and certain operating expenses related to the leases. In 2008, the Company extended the lease of its Bedford, Massachusetts headquarters facility containing research and development and manufacturing space, and in 2010 the Company extended the lease of its additional office space in Bedford, Massachusetts. Following the extension, the leases expire in September 2014. The leases contain a five year renewal option and escalating payments over the life of the lease. The Company also leases warehouse facilities in Billerica, Massachusetts. This lease expires in December 2012.

     The Company’s operating lease agreements contain scheduled rent increases which are being amortized over the terms of the agreement using the straight-line method and are included in other liabilities in the accompanying consolidated balance sheet.

Legal Proceedings

     In August 2010, Becton, Dickinson and Company, or BD, filed a lawsuit in the United States District Court in the State of New Jersey against the Company alleging that the OmniPod System infringes three of its patents. BD seeks a declaration that the Company has infringed its patents, equitable relief, including an injunction that would enjoin the Company from infringing these patents, and an unspecified award for monetary damages. The Company believes that the OmniPod System does not infringe these patents. The Company expects that this litigation will not have a material adverse impact on its financial position or results of operations. The Company believes it has meritorious defenses to this lawsuit; however, litigation is inherently uncertain and there can be no assurance as to the ultimate outcome or effect of this action. The Company does not believe it has any financial exposure at March 31, 2011.

Indemnifications

     In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future, but have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations.

     In accordance with its bylaws, the Company has indemnification obligations to its officers and directors for certain events or occurrences, subject to certain limits, while they are serving at the Company’s request in such capacity. There have been no claims to date and the Company has a director and officer insurance policy that enables it to recover a portion of any amounts paid for future claims.

9. Equity

     In October 2009, in a public offering, the Company issued and sold 6,900,000 shares of its common stock at a price to the public of $10.25 per share. In connection with the offering, the Company received total gross proceeds of $70.7 million, or approximately $66.1 million in net

proceeds after deducting underwriting discounts and offering expenses.

     In December 2010, in a public offering, the Company issued and sold 3,450,000 shares of its common stock at a price of $13.27 per share. In connection with the offering, the Company received total gross proceeds of $47.8 million, or approximately $45.4 million in net proceeds after deducting underwriting discounts and offering expenses.

     The Company grants share-based awards to employees in the form of options to purchase the Company’s common stock, the ability to purchase stock at a discounted price under the employee stock purchase plan and restricted stock units. Stock-based compensation expense related to share-based awards recognized in the quarters ended March 31, 2011 and 2010 was $2.0 million and $1.3 million, respectively, and was calculated based on awards ultimately expected to vest. At March 31, 2011, the amount of stock-based compensation capitalized as part of inventory was not material. At March 31, 2011, the Company had $19.1 million of total unrecognized compensation expense related to stock options and restricted stock units.

Stock Options

     The following summarizes the activity under the Company’s stock option plans:

						Weighted
						Average				Aggregate
		Number of				Exercise				Intrinsic
		Options(#)				Price($)				Value($)
										(in thousands)
Balance, December 31, 2010			3,018,469			$	8.74
Granted			424,000				16.65
Exercised			(330,689	)			7.43			$	3,667	(1)
Canceled			(24,139	)			12.30
Balance, March 31, 2011			3,087,641			$	9.94			$	33,200
Vested, March 31, 2011			1,684,936			$	8.20			$	21,110	(2)
Vested and expected to vest, March 31, 2011 (3)			2,572,061							$	28,525	(2)

     At the time of grant, options granted under the Company’s 2000 Stock Option and Incentive Plan (the “2000 Plan”) are typically immediately exercisable, but subject to restrictions. Therefore, under the 2000 Plan, the number of options exercisable is greater than the number of options vested until all options are fully vested. At March 31, 2011 there were 3,087,641 options outstanding with a weighted average exercise price of $9.94 per share and a weighted average remaining contractual life of 7.1 years. At March 31, 2011 there were 1,687,813 options exercisable with a weighted average exercise price of $8.21 per share and a weighted average remaining contractual life of 5.7 years.

     Employee stock-based compensation expense related to stock options recognized in the three months ended March 31, 2011 and 2010 was $1.1 million and $1.2 million, respectively, and was based on awards ultimately expected to vest. At March 31, 2011, the Company had $10.1 million of total unrecognized compensation expense related to stock options that will be recognized over a weighted average period of 1.4 years.

Employee Stock Purchase Plan

     As of March 31, 2011 and 2010, no shares were contingently issued under the employee stock purchase plan (“ESPP”). In the three months ended March 31, 2011 and 2010, the Company recorded no significant stock-based compensation charges related to the ESPP.

Restricted Stock Units

     In the three months ended March 31, 2011, the Company awarded 339,500 restricted stock units to certain employees. The restricted stock units were granted under the Company’s 2007 Stock Option and Incentive Plan (the “2007 Plan”) and vest annually over three years from the grant date. The restricted stock units granted have a weighted average fair value of $17.00 per share based on the closing price of the Company’s common stock on the date of grant. The restricted stock units granted were valued at approximately $5.8 million at their grant date, and the Company is recognizing the compensation expense over the three year vesting period. Approximately $0.9 million and $0.1 million of stock-based compensation expense related to the vesting of restricted stock units was recognized in the three months ended March 31, 2011

and 2010, respectively. Approximately $9.0 million of the fair value of the restricted stock units remained unrecognized as of March 31, 2011. Under the terms of the award, the Company will issue shares of common stock on each of the vesting dates. During the three months ended March 31, 2011, 88,822 restricted stock units originally granted in March 2010 vested. The following table summarizes the status of the Company’s restricted stock units:

						Weighted
		Number of				Average
		Shares				Fair Value
Balance, December 31, 2010			355,999			$	14.99
Granted			339,500				17.00
Vested			(88,822	)			15.08
Forfeited			(15,000	)			15.11
Balance, March 31, 2011			591,677			$	16.11

Restricted Common Stock

     During the year ended December 31, 2008, the Company awarded 4,000 shares of restricted common stock to a non-employee. The shares of restricted common stock were granted under the 2007 Plan and vest over two years. The shares of restricted common stock granted had a weighted average fair value of $8.04 per share based on the closing price of the Company’s common stock on the date of grant. The Company recognized the total compensation expense of $32,000 over the two year vesting period.

The following table summarizes the status of the Company’s restricted common stock:

						Weighted
		Number of				Average
		Shares				Fair Value
Balance, December 31, 2010			444			$	8.04

10. Income Taxes

     Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company provided a valuation allowance for the full amount of its net deferred tax asset for all periods because realization of any future tax benefit cannot be determined as more likely than not, as the Company does not expect income in the near-term.

We undertake no obligation to publicly update or revise any forward-looking statements.

Overview

     We are a medical device company that develops, manufactures and markets an insulin infusion system for people with insulin-dependent diabetes. Our proprietary OmniPod Insulin Management System consists of our disposable OmniPod insulin infusion device and our handheld, wireless Personal Diabetes Manager.

     The U.S. Food and Drug Administration, or FDA, approved the OmniPod System in January 2005. In October 2005, we shipped our first commercial OmniPod System. We have progressively expanded our marketing efforts from an initial focus in the Eastern United States to having availability of the OmniPod System in the entire United States. In January 2010, we entered into a five year distribution agreement with Ypsomed Distribution AG, or Ypsomed, to become the exclusive distributor of the OmniPod System in eleven countries, subject to approved reimbursement. Through our partnership with Ypsomed, the OmniPod System is now available in seven markets, namely Germany, the United Kingdom, France, the Netherlands, Sweden, Norway and Switzerland. We expect that Ypsomed will begin distribution of the OmniPod System, subject to approved reimbursement, in the other markets under the agreement in the last half of 2011 and 2012. In February 2011, we entered into a distribution agreement with GlaxoSmithKline Inc., or GSK, to become the exclusive distributor of the OmniPod System in Canada. We expect that GSK will begin distributing the OmniPod System, subject to approved reimbursement, in the second qurter of 2011. We focus our sales initiatives towards key diabetes practitioners, academic centers and clinics specializing in the treatment of diabetes patients, as well as individual diabetes patients.

     We currently produce the OmniPod on a partially automated manufacturing line at a facility in China operated by a subsidiary of Flextronics International Ltd., or Flextronics. We purchase complete OmniPods pursuant to our agreement with Flextronics. Under the agreement, Flextronics has agreed to supply us, as a non-exclusive supplier, with OmniPods at agreed upon prices per unit pursuant to a rolling 12-month forecast that we provide. The agreement may be terminated at any time by either party upon prior written notice given no less than a specified number of days prior to the date of termination. The specified number of days is intended to provide the parties with sufficient time to make alternative arrangements in the event of termination. By purchasing OmniPods manufactured by Flextronics in China, we have been able to substantially increase production volumes for the OmniPod and reduce our per unit production cost.

     To achieve profitability, we continue to seek to increase manufacturing volume and reduce the per-unit production cost for the OmniPod. By increasing production volumes of the OmniPod, we have been able to reduce our per-unit raw material costs and improve absorption of manufacturing overhead costs. This, as well as the introduction of our next generation OmniPod, are important as we strive to achieve profitability. We believe our current manufacturing capacity is sufficient to meet our expected 2011 demand for OmniPods.

     Our sales and marketing effort is focused on generating demand and acceptance of the OmniPod System among healthcare professionals, people with insulin-dependent diabetes, third-party payors and third-party distributors. Our marketing strategy is to build awareness for the

benefits of the OmniPod System through a wide range of education programs, social networking, patient demonstration programs, support materials, media advertisements and events at the national, regional and local levels. We are using third-party distributors to improve our access to managed care and government reimbursement programs, expand our commercial presence and provide access to additional potential patients.

     As a medical device company, reimbursement from third-party payors is an important element of our success. If patients are not adequately reimbursed for the costs of using the OmniPod System, it will be much more difficult for us to penetrate the market. We continue to negotiate contracts establishing reimbursement for the OmniPod System with national and regional third-party payors. As we expand our sales and marketing focus, increase our manufacturing capacity and expand to international markets, we will need to maintain and expand available reimbursement for the OmniPod System.

     Since our inception in 2000, we have incurred losses every quarter. In the three months ended March 31, 2011, we incurred net losses of $9.8 million. As of March 31, 2011, we had an accumulated deficit of $393.7 million. We have financed our operations through private placements of debt and equity securities, public offerings of our common stock and a private placement of our convertible debt and borrowings under certain debt agreements. As of March 31, 2011, we had $85.0 million of convertible debt outstanding.

     Our long-term financial objective is to achieve and sustain profitable growth. Our efforts for the remainder of 2011 will be focused primarily on the development, production and regulatory approval of our next generation OmniPod System, the continued reduction in our per-unit production costs on our existing product and the expansion of sales through both domestic and international markets. Achieving these objectives is expected to require additional investments in certain personnel and initiatives to allow for us to increase our penetration in the United States and international markets. We believe that we will continue to incur net losses in the near term in order to achieve these objectives. However, we believe that the accomplishment of our near term objectives will have a positive impact on our financial condition in the future.

     We believe that our cash and cash equivalents, together with the cash expected to be generated from product sales, will be sufficient to meet our projected operating and debt service requirements for the next twelve months.

Financial Operations Overview

     Revenue. We derive nearly all of our revenue from the sale of the OmniPod System directly to patients and third-party distributors who resell the product to diabetes patients. The OmniPod System is comprised of two devices: the OmniPod, a disposable insulin infusion device that the patient wears for up to three days and then replaces; and the Personal Diabetes Manager, or PDM, a handheld device much like a personal digital assistant that wirelessly programs the OmniPod with insulin delivery instructions, assists the patient with diabetes management and incorporates a blood glucose meter. Revenue is derived from the sale to new customers or third-party distributors of OmniPods and Starter Kits, which include the PDM, the OmniPod System User Guide and our Interactive Training CD, and from the subsequent sales of OmniPods to existing customers. Customers generally order a three-month supply of OmniPods. We are currently selling our product through our partnership with Ypsomed in seven markets, namely Germany, the United Kingdom, France, the Netherlands, Sweden, Norway and Switzerland. We expect that Ypsomed will begin distributing the OmniPod System, subject to approved reimbursement, in the other markets under the agreement in the last half of 2011 or in 2012. In February 2011, we entered into a distribution agreement with GSK to become the exclusive distributor of the OmniPod System in Canada. We expect that GSK will begin distributing the OmniPod System, subject to approved reimbursement, in the second quarter of 2011.

     In March 2008, we received a cash payment from Abbott Diabetes Care, Inc., or Abbott, for an agreement fee in connection with execution of the first amendment to the development and license agreement with Abbott. We are recognizing the payment as revenue over the five year term of the agreement. Under the amended Abbott agreement, beginning July 1, 2008, Abbott agreed to pay us certain amounts for services performed in connection with each sale of a PDM that includes an Abbott Discrete Blood Glucose Monitor to certain customers. In July 2010, we entered into a second amendment to the development and license agreement with Abbott. Under the terms of the second amendment, Abbott agreed to pay certain amounts to us for services we performed in connection with each sale of a PDM that includes an Abbott Discrete Blood Glucose Monitor to customers in certain additional territories. We recognize the revenue related to this portion of the Abbott agreement at the time we meet the criteria for revenue recognition, typically at the time of the sale of the PDM to a new patient. In the three months ended March 31, 2011 and 2010, we recognized $1.2 million and $1.1 million of revenue, respectively, related to the amended Abbott agreement.

     As of March 31, 2011 and December 31, 2010, we had deferred revenue of $2.3 million and $4.8 million, respectively. These amounts include product-related revenue as well as the unrecognized portion of the agreement fee related to the Abbott agreement. For the year ending December 31, 2011, we expect our revenue to continue to increase as we gain new customers in the United States and continue expansion in Europe and certain other international markets. Increased revenue will be dependent upon the success of our sales efforts, our ability to produce OmniPods in sufficient volumes and other risks and uncertainties.

     Cost of revenue. Cost of revenue consists primarily of raw material, labor, warranty and overhead costs related to the OmniPod System. Cost of revenue also includes depreciation, freight and packaging costs. The increase in our OmniPod production volume, including the production of our next generation OmniPod, together with our ability to gain cost savings on our bill of materials, is expected to reduce the per-unit cost of manufacturing the OmniPods by allowing us to reduce our direct costs and spread our fixed and semi-fixed overhead costs over a greater number of units.

     Research and development. Research and development expenses consist primarily of personnel costs within our product development, regulatory and clinical functions, and the costs of market studies and product development projects. We expense all research and development costs as incurred. For the year ending December 31, 2011, we expect overall research and development spending to decrease slightly compared to 2010 as we have completed a significant amount of the development work on our next generation Omnipod.

     General and administrative. General and administrative expenses consist primarily of salaries and other related costs for personnel serving the executive, finance, information technology and human resource functions, as well as legal fees, accounting fees, insurance costs, bad debt expenses, shipping, handling and facilities-related costs. We expect general and administrative expenses to increase slightly in 2011 compared to 2010 as we grow our administrative functions to meet the needs of our expanding business.

     Sales and marketing. Sales and marketing expenses consist primarily of personnel costs within our sales, marketing, reimbursement support, customer support and training functions, sales commissions paid to our sales representatives and costs associated with participation in medical conferences, physician symposia and promotional activities, including distribution of units used in our demonstration kit programs. We expect sales and marketing expenses to increase slightly compared to 2010 to expedite and support the growth of our business.

Comparison of the Three Months Ended March 31, 2011 and 2010

Revenue

     Our total revenue was $28.3 million and $20.8 million for the three months ended March 31, 2011 and 2010, respectively. The increase in revenue is primarily due to continued adoption of the OmniPod System by patients in the United States and internationally. We expect our revenue to increase as we continue to add new patients, introduce the OmniPod System in additional territories, and generate a higher volume of reorders based on our expanding patient base.

Cost of Revenue

     Cost of revenue was $14.7 million and $12.4 million for the three months ended March 31, 2011 and 2010, respectively. The increase in cost of revenue is primarily due to a significant increase in sales volume offset by cost efficiencies related to the bill of material and production volume. Revenue increased by 36% from the three months ended March 31, 2010 to the three months ended March 31, 2011, while cost of revenue increased by 19% in the same period as a result of these cost efficiencies. Gross margin improved by 8% as described by the increased sales and efficiencies above.

Research and Development

     Research and development expenses increased $0.7 million, or 19%, to $4.6 million for the three months ended March 31, 2011, compared to $3.8 million for the same period in 2010. The increase was primarily a result of $0.4 million increase in employee related expenses, of which $0.2 million was from an increase in stock-based compensation, and a $0.3 million increase for materials and equipment utilized in the development of our next generation OmniPod System.

General and Administrative

     General and administrative expenses increased $0.2 million, or 4%, to $7.2 million for the three months ended March 31, 2011, compared to $7.0 million for the same period in 2010. The increase in general and administrative expenses was primarily due to an increase of $0.8 million in employee related expenses including key management additions, merit increases, stock-based compensation of $0.2 million, and a $0.2 million increase in product shipping expenses. These increases were offset by a decrease of $0.7 million in allowances and write-offs of trade accounts receivable.

Sales and Marketing

     Sales and marketing expenses increased $0.7 million, or 8%, to $9.0 million for the three months ended March 31, 2011, compared to $8.3 million for the same period in 2010. The increase in sales and marketing expenses was due to an increase of $0.7 million in employee related expenses including employee additions, merit increases, and a $0.5 million increase in stock-based compensation. The increase is primarily a result of growth within our sales team.

Other Expense, Net

     Net interest expense was $2.6 million for the three months ended March 31, 2011, compared to $3.8 million for the same period in 2010. The decrease in net interest expense was primarily due to cash interest savings of $0.7 million and $0.6 million of non-cash interest savings on our Facility Agreement which was repaid in December 2010.

Liquidity and Capital Resources

     We commenced operations in 2000 and to date we have financed our operations primarily through private placements of common and preferred stock, secured indebtedness, public offerings of our common stock and issuance of convertible debt. As of March 31, 2011, we had $104.5 million in cash and cash equivalents. We believe that our current cash and cash equivalents, together with the cash expected to be generated from product sales, will be sufficient to meet our projected operating and debt service requirements for at least the next twelve months.

Equity

     In October 2009, in a public offering, we issued and sold 6,900,000 shares of our common stock at a price to the public of $10.25 per share. In connection with this offering, we received total gross proceeds of $70.7 million, or approximately $66.1 million in net proceeds after deducting underwriter discounts and offering expenses.

     In December 2010, we issued and sold 3,450,000 shares of our common stock pursuant to an underwriting agreement with Canaccord Genuity at a price of $13.27 per share. In connection with the offering, we received total gross proceeds of $47.8 million, or approximately $45.4 million in net proceeds after deducting underwriting discounts and offering expenses. Approximately $33.3 million of the proceeds was used to repay all amounts outstanding under our Facility Agreement.

Convertible Notes

     In June 2008, we sold $85.0 million principal amount of 5.375% Notes due June 15, 2013 (the “5.375% Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The interest rate on the notes is 5.375% per annum on the principal amount from June 16, 2008, payable semi-annually in arrears in cash on December 15 and June 15 of each year. The 5.375% Notes are convertible into our common stock at an initial conversion rate of 46.8467 shares of common stock per $1,000 principal amount of the 5.375% Notes, which is equivalent to a conversion price of approximately $21.35 per share, representing a conversion premium of 34% to the last reported sale price of our common stock on the NASDAQ Global Market on June 10, 2008, per $1,000 principal amount of the 5.375% Notes, subject to adjustment under certain circumstances, at any time beginning on March 15, 2013 or under certain other circumstances and prior to the close of business on the business day immediately preceding the final maturity date of the notes. The 5.375% Notes will be convertible for cash up to their principal amount and shares of our common stock for the remainder of the conversion value in excess of the principal amount. We do not have the right to redeem any of the 5.375% Notes prior to maturity. If a fundamental change, as defined in the Indenture for the 5.375% Notes, occurs at any time prior to maturity, holders of the 5.375% Notes may require us to repurchase their notes in whole or in part for cash equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, including any additional interest, to, but excluding, the date of repurchase.

     If a holder elects to convert its 5.375% Notes upon the occurrence of a make-whole fundamental change, as defined in the Indenture for the 5.375% Notes, the holder may be entitled to receive an additional number of shares of common stock on the conversion date. These additional shares are intended to compensate the holders for the loss of the time value of the conversion option, and are set forth in the Indenture for the 5.375% Notes. In no event will the shares issuable upon conversion of a note exceed 62.7746 per $1,000 principal amount (subject to adjustment as described in the Indenture for the 5.375% Notes).

     We recorded a debt discount of $26.9 million to equity to reflect the value of our nonconvertible debt borrowing rate of 14.5% per annum. This debt discount is being amortized as interest expense over the five year term of the 5.375% Notes.

     We incurred interest expense related to the 5.375% Notes of approximately $2.7 million for the three months ended March 31, 2011, of which approximately $1.6 million relates to amortization of the debt discount and deferred financing costs and $1.1 million relates to cash

interest. We incurred interest expense related to the 5.375% Notes of approximately $2.5 million for the three months ended March 31, 2010, of which approximately $1.4 million related to amortization of the debt discount and deferred financing costs and $1.1 million related to cash interest. We incurred deferred financing costs related to this offering of approximately $3.5 million, of which $1.1 million has been reclassified as an offset to the amount allocated to equity. The remainder is recorded in the consolidated balance sheet and is being amortized as a component of interest expense over the five year term of the notes.

     As of March 31, 2011, the outstanding amounts related to the 5.375% Notes of $70.9 million are included in long-term debt in the consolidated balance sheet and reflect the debt discount of $14.1 million. As of December 31, 2010, the outstanding amounts related to the 5.375% Notes of $69.4 million are included in long-term debt and reflect the debt discount of $15.6 million. The debt discount represents the difference between our nonconvertible debt borrowing rate and the stated rate on the 5.375% Notes and includes the equity allocation of $25.8 million (which represents $26.9 million less the $1.1 million of allocated financing costs) offset by the accretion of the debt discount through interest expense from the issuance date in 2008 over the five year term of the notes. As of March 31, 2011, the 5.375% Notes have a remaining life of 2.25 years.

     We received net proceeds of approximately $81.5 million from the 5.375% Notes offering. Approximately $23.2 million of the net proceeds from this offering was used to repay and terminate our then-existing term loan, including outstanding principal and accrued and unpaid interest of $21.8 million, a prepayment fee related to the term loan of approximately $0.4 million, a termination fee of $0.9 million and incurred certain other expenses related to the prepayment and termination of the term loan. In connection with this term loan, we issued warrants to the lenders to purchase up to 247,252 shares of Series E preferred stock at a purchase price of $3.64 per share. The warrants automatically converted into warrants to purchase common stock on a 1-for-2.6267 basis at a purchase price of $9.56 per share at the closing of our initial public offering in May 2007. Warrants to purchase 62,752 shares of our common stock remain outstanding at March 31, 2011 and expire on December 27, 2013.

Facility Agreement and Common Stock Warrants

     In March 2009, we entered into a Facility Agreement with certain institutional accredited investors, pursuant to which the investors agreed to loan us up to $60 million, subject to the terms and conditions set forth in the Facility Agreement. Total financing costs, including the transaction fee were $3.0 million and were being amortized as interest expense over the forty-two month term of the Facility Agreement.

     In connection with the execution of the Facility Agreement, we issued to the lenders fully exercisable warrants to purchase an aggregate of 3.75 million shares of our common stock at an exercise price of $3.13 per share. The warrants qualified for permanent treatment as equity, and their relative fair value of $6.1 million on the issuance date was recorded as additional paid-in capital and debt discount. The debt discount was amortized as non-cash interest expense over the term of the loan.

          In September 2009, we entered into an Amendment to the Facility Agreement whereby we repaid the $27.5 million originally drawn and promptly drew down the remaining $32.5 million available under the Facility Agreement. The annual interest rate was 8.5%, payable quarterly in arrears. In connection with the Amendment to the Facility Agreement, we entered into a Securities Purchase Agreement with the lenders whereby we sold 2,855,659 shares of our common stock to the lenders at $9.63 per share, a $1.9 million discount based on the closing price of our common stock of $10.28 on that date. We recorded the $1.9 million as additional paid-in capital and debt discount and amortized it to interest expense over the remaining term of the loan. We received aggregate proceeds of $27.5 million in connection with the sale of our shares. All principal amounts outstanding under the Facility Agreement were payable in September 2012.

     In June 2010, we entered into a Second Amendment to the Facility Agreement whereby we paid a $0.5 million amendment fee to the lenders in exchange for the reduction of the prepayment penalties as well as the modification of certain other terms in the Facility Agreement. The fee was recorded as additional debt discount and amortized to interest expense over the remaining term of the loan.

     In December 2010, we paid $33.3 million to the lenders, of which $32.5 million related to principal and $0.8 million related to interest and prepayment fees, to extinguish this debt. We recorded a non-cash interest charge of $7.0 million in the fourth quarter of 2010 related to the write-off of the remaining debt discount and financing costs included in other assets which were amortized to interest expense over the term of the debt.

     In the three months ended March 31, 2010, we recorded approximately $0.7 million of cash interest related to the Facility Agreement and $0.6 million of non-cash interest. Non-cash interest in the three months ended March 31, 2010 consisted of amortization of the debt discount from the issuance of warrants and transaction fee in March 2009, amortization of the discount on the shares sold in connection with the amendment in September 2009, and amortization of the issuance costs associated with the debt. No interest related to the Facility Agreement was recorded in the three months ended March 31, 2011 as the debt was repaid in December 2010.

     As of March 31, 2011, all warrants to acquire 3.75 million shares of our common stock issued in connection with the Facility Agreement were exercised.

Operating Activities

     The following table sets forth the amounts of cash used in operating activities and net loss for each of the periods indicated:

		Three Months Ended March 31,
		2011				2010
		(In thousands)
Cash used in operating activities		$	(7,328	)		$	(9,178	)
Net loss		$	(9,848	)		$	(14,491	)

     For each of the periods above, the net cash used in operating activities was attributable primarily to the growth of our operations after adjustment for non-cash. Adjustments for non-cash items were approximately $5.0 million and $5.8 million in the three months ended March 31, 2011 and March 31, 2010, respectively. Significant uses of cash from operations in the three months ended March 31, 2011 include increases in prepaid expenses and other current assets for the renewal of annual infrastructure and insurance contracts, and inventories due to increased production and a decrease in deferred revenue as a result of revenue recognized on certain distributor shipments. These uses of cash in the three months ended March 31, 2011 were offset by a decrease in accounts receivable, primarily attributable to improved collections. Accounts receivable are shown net of allowances for doubtful accounts in the consolidated balance sheets.

Investing and Financing Activities

     The following table sets forth the amounts of cash used in investing activities and cash provided by financing activities for each of the periods indicated:

		Three Months Ended March 31,
		2011				2010
		(In thousands)
Cash used in investing activities		$	(2,897	)		$	(1,090	)
Cash provided by financing activities		$	1,977			$	610

     Cash used in investing activities in both periods was primarily for the purchase of fixed assets for use in the development and manufacturing of the OmniPod System. Our cash used in investing activities has increased significantly in the three months ended March, 31, 2011, compared to the three months ended March 31, 2010, as we purchased equipment to be used to manufacture our next generation product. Capital expenditures are expected to continue to increase in 2011 compared to 2010. Cash provided by financing activities in the three months ended March 31, 2011 and March 31, 2010 mainly consisted of the net proceeds from the issuance of common stock in connection with the exercise of employee stock options.

Lease Obligations

     We lease our facilities, which are accounted for as operating leases. The lease of our facilities in Bedford and Billerica, Massachusetts, generally provides for a base rent plus real estate taxes and certain operating expenses related to the lease. All operating leases contain renewal options and escalating payments over the term of the lease. As of March 31, 2011, we had an outstanding letter of credit which totaled $0.2 million to cover our security deposits for lease obligations.

Off-Balance Sheet Arrangements

     As of March 31, 2011, we did not have any off-balance sheet financing arrangements.

Critical Accounting Policies and Estimates

     Our financial statements are based on the selection and application of generally accepted accounting principles, which require us to make estimates and assumptions about future events that affect the amounts reported in our financial statements and the accompanying notes. Future events and their effects cannot be determined with certainty. Therefore, the determination of estimates requires the exercise of judgment. Actual results could differ from those estimates, and any such differences may be material to our financial statements. We believe that the policies set forth below may involve a higher degree of judgment and complexity in their application than our other accounting policies and represent the critical accounting policies and estimates used in the preparation of our financial statements. If different assumptions or conditions were to prevail, the results could be materially different from our reported results.

Revenue Recognition

     We generate nearly all of our revenue from sales of our OmniPod Insulin Management System to diabetes patients and third-party distributors who resell the product to diabetes patients. The initial sale to a new customer or a third-party distributor typically includes OmniPods and a Starter Kit, which is comprised of the PDM, the OmniPod System User Guide and our OmniPod System Interactive Training CD. Subsequent sales to existing customers typically consist of additional OmniPods.

     Revenue recognition requires that persuasive evidence of a sales arrangement exists, delivery of goods occurs through transfer of title and risk and rewards of ownership, the selling price is fixed or determinable and collectibility is reasonably assured. With respect to these criteria:

•

The evidence of an arrangement generally consists of a physician order form, a patient information form, and if applicable, third-party

		insurance approval for sales directly to patients or a purchase order for sales to a third-party distributor.
•		Transfer of title and risk and rewards of ownership are passed to the patient or third-party distributor typically upon shipment of the products.
•		The selling prices for all sales are fixed and agreed with the patient or third-party distributor, and, if applicable, the patient’s third-party insurance provider(s) prior to shipment and are based on established list prices or, in the case of certain third-party insurers, contractually agreed upon prices. Provisions for discounts and rebates to customers are established as a reduction to revenue in the same period the related sales are recorded.

     We assess whether the different elements qualify for separate accounting. We recognize revenue for the initial shipment to a patient or other third-party once all elements have been delivered.

     We offer a 45-day right of return for our Starter Kits sales, and we defer revenue to reflect estimated sales returns in the same period that the related product sales are recorded. Returns are estimated through a comparison of historical return data to their related sales. Historical rates of return are adjusted for known or expected changes in the marketplace when appropriate. Historically, sales returns have amounted to approximately 3% of gross product sales.

     When doubt exists about reasonable assuredness of collectibility from specific customers, we defer revenue from sales of products to those customers until payment is received.

     In March 2008, we received a cash payment from Abbott Diabetes Care, Inc., or Abbott, for an agreement fee in connection with execution of the first amendment to the development and license agreement between us and Abbott. We recognize the agreement fee received from Abbott over the initial five year term of the agreement, and the non-current portion of the agreement fee is included in other long-term liabilities. Under the amended Abbott agreement, beginning July 1, 2008, Abbott agreed to pay us certain amounts for services performed in connection with each sale of a PDM that includes an Abbott Discrete Blood Glucose Monitor to certain customers. In July 2010, we entered into a second amendment to the development and license agreement with Abbott. Under the terms and conditions of the second amendment, Abbott agreed to pay certain amounts to us for services performed in connection with each sale of a PDM that includes an Abbott Discrete Blood Glucose Monitor to customers in certain additional territories. We recognize revenue related to this portion of the Abbott agreement at the time we meet the criteria for revenue recognition, typically at the time the revenue is recognized on the sale of the PDM to the patient. In the three months ended March 31, 2011, we recognized revenue related to the amended Abbott agreement of $1.2 million. In the three months ended March 31, 2010, we recognized revenue related to the amended Abbott agreement of $1.1 million. There was no impact to cost of revenue related to this agreement.

     We had deferred revenue of $2.3 million as of March 31, 2011. The deferred revenue recorded as of March 31, 2011 was comprised of product-related revenue as well as the non-amortized agreement fee related to the Abbott agreement.

Income Taxes

     FASB ASC 740-10, Income Taxes, clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements. FASB ASC 740-10 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. In addition, FASB ASC 740-10 provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. As of March 31, 2011, we had $0.2 million of unrecognized tax benefits recorded.

Stock-Based Compensation

     We account for stock-based compensation under the provisions of FASB ASC 718-10, Compensation — Stock Compensation. FASB ASC 718-10 requires all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values.

     We have continued to apply the minimum value method in future periods to equity awards outstanding that were originally measured using this method. We use the Black-Scholes option pricing model to determine the weighted average fair value of options granted. We determine the intrinsic value of restricted stock and restricted stock units based on the closing price of our common stock on the date of grant. We recognize the compensation expense of share-based awards on a straight-line basis over the vesting period of the award.

     The determination of the fair value of share-based payment awards utilizing the Black-Scholes model is affected by the stock price and a number of assumptions, including expected volatility, expected life, risk-free interest rate and expected dividends. The expected life of the awards is estimated based on the “SEC Shortcut Approach” as defined in SAB 107, which is the midpoint between the vesting date and the end of the contractual term. The risk-free interest rate assumption is based on observed interest rates appropriate for the terms of the awards. The dividend yield assumption is based on company history and expectation of paying no dividends. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Stock-based compensation expense recognized in the financial statements is based on awards that are ultimately expected to vest. We evaluate the assumptions used to value the awards on a quarterly basis and if factors change and different assumptions are utilized, stock-based compensation expense may differ significantly from

what has been recorded in the past. If there are any modifications or cancellations of the underlying unvested securities, we may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense.

     In the three months ended March 31, 2011 and March 31, 2010, we recorded $2.0 million and $1.3 million of stock based compensation expense, respectively.

Accounts Receivable and Allowance for Doubtful Accounts

     Accounts receivable consist of amounts due from third-party payors, patients and third-party distributors. The allowance for doubtful accounts is recorded in the period in which revenue is recorded or at the time potential collection risk is identified. We estimate our allowance based on historical experience, assessment of specific risk, discussions with individual customers and various assumptions and estimates that we believe to be reasonable under the circumstances.

Warranty

     We provide a four year warranty on our PDMs and may replace any OmniPods that do not function in accordance with product specifications. We estimate our warranty at the time the product is shipped based on historical experience and the estimated cost to service the claims. Cost to service the claims reflects the current product cost which has been decreasing over time. As these estimates are based on historical experience, and we continue to introduce new versions of existing products, we also consider the anticipated performance of the product over its warranty period in estimating warranty reserves. At March 31, 2011 and December 31, 2010, the warranty reserve was $1.8 million and $1.9 million, respectively.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

     We do not use derivative financial instruments in our investment portfolio and have no foreign exchange contracts. Our financial instruments consist of cash, cash equivalents, accounts receivable, accounts payable, accrued expenses and long-term obligations. We consider investments that, when purchased, have a remaining maturity of 90 days or less to be cash equivalents. The primary objectives of our investment strategy are to preserve principal, maintain proper liquidity to meet operating needs and maximize yields. To minimize our exposure to an adverse shift in interest rates, we invest mainly in cash equivalents. We do not believe that a 10% change in interest rates would have a material impact on the fair value of our investment portfolio or our interest income.

     As of March 31, 2011, we had outstanding debt recorded on our consolidated balance sheet of $70.9 million related to our 5.375% Notes. As the interest rate on the 5.375% Notes is fixed, changes in interest rates do not affect the value of our debt.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

     As of March 31, 2011, our management conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) under the supervision and with the participation of our chief executive officer and chief financial officer. In designing and evaluating our disclosure controls and procedures, we and our management recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily was required to apply its judgment in evaluating and implementing possible controls and procedures. Based upon that evaluation of our disclosure controls and procedures as of March 31, 2011, our chief executive officer and chief financial officer concluded that they believe that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

     There were no changes in our internal control over financial reporting that occurred during the three months ended March 31, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

     In August 2010, Becton, Dickinson and Company, or BD, filed a lawsuit in the United States District Court in the State of New Jersey against us alleging that the OmniPod System infringes three of its patents. BD seeks a declaration that we have infringed its patents, equitable relief, including an injunction that would enjoin us from infringing these patents, and an unspecified award for monetary damages. We believe that the OmniPod System does not infringe these patents. We do not expect this litigation to have a material adverse impact on our financial position or results of operations. We believe we have meritorious defenses to this lawsuit; however, litigation is inherently uncertain and there can be no assurance as to the ultimate outcome or effect of this action. We do not believe we have any financial exposure at March 31, 2011.

     We are, from time to time, involved in the normal course of business in various legal proceedings, including intellectual property, contract

employment and product liability suits. Although we are unable to quantify the exact financial impact of any of these matters, we believe that none of these currently pending matters will have an outcome material to our financial condition or business.

Item 1A. Risk Factors

     In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2010, which could materially affect our business, financial condition or future results. These risks are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. There have been no material changes in our risk factors from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2010.
