1. Business Overview

Company Description

Cardiovascular Systems, Inc. was incorporated as Replidyne, Inc. in Delaware in 2000. On February 25, 2009, Replidyne, Inc. completed its reverse merger with Cardiovascular Systems, Inc., a Minnesota corporation incorporated in 1989 (“CSI-MN”), in accordance with the terms of the Agreement and Plan of Merger and Reorganization, dated as of November 3, 2008 (the “Merger Agreement”). Pursuant to the Merger Agreement, CSI-MN continued after the merger as the surviving corporation and a wholly-owned subsidiary of Replidyne. At the effective time of the merger, Replidyne, Inc. changed its name to Cardiovascular Systems, Inc. (“CSI”) and CSI-MN merged with and into CSI, with CSI continuing after the merger as the surviving corporation.

The Company develops, manufactures and markets devices for the treatment of vascular diseases. The Company’s primary products, the Diamondback 360° PAD System, the Predator 360° PAD System, and the Stealth 360° PAD System, are catheter-based platforms capable of treating a broad range of plaque types in leg arteries both above and below the knee and address many of the limitations associated with existing treatment alternatives. This includes calcified lesions, which are more difficult and expensive to treat and have higher rates of adverse events and restenosis. Prior to the merger, Replidyne was a biopharmaceutical company focused on discovering, developing, in-licensing and commercializing innovative anti-infective products.

2. Summary of Significant Accounting Policies

Interim Financial Statements

The Company has prepared the unaudited interim consolidated financial statements and related unaudited financial information in the footnotes in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. The year-end consolidated balance sheet was derived from the Company’s audited consolidated financial statements, but does not include all disclosures as required by GAAP. These interim consolidated financial statements reflect all adjustments consisting of normal recurring accruals, which, in the opinion of management, are necessary to state fairly the Company’s consolidated financial position, the results of its operations and its cash flows for the interim periods. These interim consolidated financial statements should be read in conjunction with the consolidated annual financial statements and the notes thereto included in the Form 10-K filed by the Company with the SEC on September 12, 2011. The nature of the Company’s business is such that the results of any interim period may not be indicative of the results to be expected for the entire year.

Fair Value of Financial Instruments

The Company has adopted fair value guidance issued by the Financial Accounting Standards Board (“FASB”), which provides a framework for measuring fair value under GAAP and expands disclosures about fair value measurements.

The fair value guidance classifies inputs into the following hierarchy:

Level 1 Inputs— quoted prices in active markets for identical assets and liabilities

Level 2 Inputs— observable inputs other than quoted prices in active markets for identical assets and liabilities

Level 3 Inputs— unobservable inputs

6

The following table sets forth the fair value of the Company’s financial instruments that were measured on a recurring basis as of March 31, 2012. Assets are measured on a recurring basis if they are remeasured at least annually:

	Level 3
	Conversion Option
Balance at June 30, 2011	$	925
Issuance of $1,500 in convertible notes		295
Change in conversion option valuation		(454	)
Conversion of $500 convertible note		(182	)
Balance at March 31, 2012	$	584

The fair value of the conversion option is related to the loan and security agreement with Partners for Growth (described in Note 4) and has been included in debt conversion option and other assets on the balance sheet. The Monte Carlo option pricing model used to determine the value of the conversion option included various inputs including historical volatility, stock price simulations, and assessed behavior of the Company and Partners for Growth based on those simulations. Based upon these inputs, the Company considers the conversion option to be a Level 3 investment.

As of March 31, 2012, the Company believes that the carrying amounts of its other financial instruments, including accounts receivable, accounts payable and accrued liabilities approximate their fair value due to the short-term maturities of these instruments. The carrying amount of long-term debt approximates fair value based on interest rates currently available for debt with similar terms and maturities.

Use of Estimates

The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Stock-Based Compensation

The Company recognizes stock-based compensation expense in an amount equal to the fair value of share-based payments computed at the date of grant. The fair value of all stock option and restricted stock awards are expensed in the consolidated statements of operations ratably over the related vesting period.

Revenue Recognition

The Company sells the majority of its products via direct shipment to hospitals or clinics. The Company recognizes revenue when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred; the sales price is fixed or determinable; and collectability is reasonably assured. These criteria are met at the time of delivery when the risk of loss and title passes to the customer. The Company records estimated sales returns, discounts and rebates as a reduction of net sales in the same period revenue is recognized.

Recent Accounting Pronouncements

In May 2011, the FASB issued guidance to amend the accounting and disclosure requirements on fair value measurements. The new guidance limits the highest-and-best-use measure to nonfinancial assets, permits certain financial assets and liabilities with offsetting positions in market or counterparty credit risks to be measured at a net basis, and provides guidance on the applicability of premiums and discounts. Additionally, the new guidance expands the disclosures on Level 3 inputs by requiring quantitative disclosure of the unobservable inputs and assumptions, as well as description of the valuation processes and the sensitivity of the fair value to changes in unobservable inputs. The new guidance became effective for the Company beginning January 1, 2012. Other than requiring additional disclosures, there was no material impact on our consolidated financial statements upon adoption.

In June 2011, the FASB issued guidance requiring that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. The new guidance will be effective for the Company beginning July 1, 2012. Other than requiring additional disclosures, the Company does not anticipate material impacts on its consolidated financial statements upon adoption as the Company has no other comprehensive income.

4. Debt

Loan and Security Agreement with Silicon Valley Bank

On March 29, 2010, the Company entered into an amended and restated loan and security agreement with Silicon Valley Bank. The agreement was amended on December 27, 2011. The agreement, as amended, includes a $12,000 term loan and a $15,000 line of credit. The terms of each of these loans are as follows:

• The $12,000 term loan has an initial interest rate of 8.0%, which can be reduced to 7.0% based on the achievement of positive EBITDA for the trailing six month period. The term loan has a 36 month maturity, with repayment terms that include interest only payments during the first six months, followed by 30 equal principal payments of $400 plus interest, and a final payment of $100 due at maturity. This term loan also includes an acceleration provision that requires the Company to pay the entire outstanding balance, plus a penalty ranging from 1.0% to 3.0% of the principal amount, upon prepayment or the occurrence and continuance of an event of default. The balance outstanding on the term loan at March 31, 2012 was $11,664. The unamortized discount associated with warrants issued to Silicon Valley Bank in connection with the loan and other fees paid to the lender will be amortized over the 36 month maturity period. This amendment is being accounted for as a debt modification.

• The $15,000 line of credit expires March 31, 2014 and has a floating interest rate equal to Silicon Valley Bank’s prime rate, plus 2.0%, with an interest rate floor of 6.0%. Interest on borrowings is due monthly and the principal balance is due at maturity. Borrowings on the line of credit are based on (a) 80% of eligible domestic receivables, plus (b) the lesser of 40% of eligible inventory or 25% of eligible domestic receivables or $2,500, minus (c) to the extent in effect, certain loan reserves as defined in the agreement. Accounts receivable receipts are deposited into a lockbox account in the name of Silicon Valley Bank. The line of credit is subject to non-use fees, annual fees, and cancellation fees. The agreement provides that upon the achievement of certain financial covenants, the amount reducing available borrowings will be zero, however, if certain financial covenants are not met, 75% of the outstanding principal balance of the $12,000 term loan reduces available borrowings under the line of credit. There was not an outstanding balance on the line of credit at March 31, 2012.

Borrowings from Silicon Valley Bank are secured by all of the Company’s assets. The borrowings are subject to prepayment penalties and financial covenants, including maintaining certain liquidity and fixed charge coverage ratios, and certain three-month EBITDA targets. The Company was in compliance with all financial covenants as of March 31, 2012. The agreement also includes subjective acceleration clauses which permit Silicon Valley Bank to accelerate the due date under certain circumstances, including, but not limited to, material adverse effects on the Company’s financial status or otherwise. Any non-compliance by the Company under the terms of debt arrangements could result in an event of default under the Silicon Valley Bank loan, which, if not cured, could result in the acceleration of this debt.

Loan and Security Agreement with Partners for Growth

On April 14, 2010, the Company entered into a loan and security agreement with Partners for Growth III, L.P. (PFG). The agreement, as amended, provides that PFG will make loans to the Company up to $4,000. The agreement has a maturity date of April 14, 2015. The loans bear interest at a floating per annum rate equal to 2.75% above Silicon Valley Bank’s prime rate, and such interest is payable monthly. The principal balance of and any accrued and unpaid interest on any notes are due on the maturity date and may not be prepaid by the Company at any time in whole or in part. On August 23, 2011, the loan and security agreement was amended to provide that PFG will make loans to the Company up to $5,000. All other terms of the original agreement remain the same. On December 27, 2011, the loan and security agreement, as amended, raises the total amount of indebtedness that the Company may accrue under the term loan portion of the amended and restated loan and security agreement with Silicon Valley Bank, as amended, from $10,000 to $12,000.

As of March 31, 2012, PFG has provided the Company the following three loans totaling $5,000 that are outstanding: (i) a $3,500 loan dated June 30, 2011 with a conversion price of $13.64, (ii) a $500 loan dated August 4, 2011, as amended and restated August 24, 2011, with a conversion price of $15.30, and (iii) a $1,000 loan dated August 24, 2011 with a conversion price of $13.42. At any time prior to the maturity date, PFG may at its option convert any of the outstanding loans into shares of the Company’s common stock at the applicable conversion price, which in each case equaled the ten-day volume weighted average price per share of the Company’s common stock prior to the issuance date of each note. The Company may also effect at any time a mandatory conversion of amounts, subject to certain terms, conditions and limitations provided in the agreement, including a requirement that the ten-day volume weighted average price of the Company’s common stock prior to the date of conversion is at least 15% greater than the conversion price. The Company may reduce the conversion price to a price that represents a 15% discount to the ten-day volume weighted average price of its common stock to satisfy this condition and effect a mandatory conversion. During the nine months ended March 31, 2012, PFG, at its option, converted a $500 loan (at par) into 40,323 shares of the Company’s common stock in accordance with the conversion terms set forth in the agreement. The Company has reflected a net expense of $636 for the nine months ended March 31, 2012 as a component of interest and other, net on the accompanying statement of operations, which represents the net effect of (i) the write-off of the conversion option on the converted loan, (ii) the write-off of the unamortized debt premium on the converted loan and (iii) the change in fair value of the conversion options on all outstanding loans. The balance outstanding under the loan and security agreement at March 31, 2012 was $5,627. The net unamortized premium associated with warrants issued to PFG in connection with the loan, a beneficial conversion feature, and other fees paid to the lender will be amortized over the remaining maturity period.

The loans are secured by certain of the Company’s assets, and the agreement contains customary covenants limiting the Company’s ability to, among other things, incur debt or liens, make certain investments and loans, effect certain redemptions of and declare and pay certain dividends on its stock, permit or suffer certain change of control transactions, dispose of collateral, or change the nature of its business. In addition, the PFG loan and security agreement contains financial covenants requiring the Company to maintain certain liquidity and fixed charge coverage ratios, and certain three-month EBITDA targets. The Company was in compliance with all financial covenants at March 31, 2012. If the Company does not comply with the various covenants, PFG may, subject to various customary cure rights, decline to provide additional loans, require amortization of the loan over its remaining term, or require the immediate payment of all amounts outstanding under the loan and foreclose on any or all collateral, depending on which financial covenants are not maintained.

As of March 31, 2012, debt maturities were as follows:

Three months ending June 30, 2012	$	—
2013		4,800

6. Stock Options and Restricted Stock Awards

The Company has a 2007 Equity Incentive Plan (the “2007 Plan”), which was assumed from CSI-MN, under which options to purchase common stock and restricted stock awards have been granted to employees, directors and consultants at exercise prices determined by the board of directors; and also in connection with the merger the Company assumed options and restricted stock awards granted by CSI-MN under its 1991 Stock Option Plan (the “1991 Plan”) and 2003 Stock Option Plan (the “2003 Plan”) (the 2007 Plan, the 1991 Plan and the 2003 Plan collectively, the “Plans”). The 1991 Plan and 2003 Plan permitted the granting of incentive stock options and nonqualified options. A total of 485,250 shares of common stock were originally reserved for issuance under the 1991 Plan, but with the approval of the 2003 Plan no additional options were granted under it. A total of 2,458,600 shares of common stock were originally reserved for issuance under the 2003 Plan, but with the approval of the 2007 Plan no additional options will be granted under it.

The 2007 Plan originally allowed for the granting of up to 1,941,000 shares of common stock as approved by the board of directors in the form of nonqualified or incentive stock options, restricted stock awards, restricted stock unit awards, performance share awards, performance unit awards or stock appreciation rights to officers, directors, consultants and employees of the Company. The Plan was amended in February 2009 to increase the number of authorized shares to 2,509,969. Generally, options or shares granted under the 2007 Plan expire ten years from the date of grant and vest over three years. The amended 2007 Plan includes a renewal provision whereby the number of shares shall automatically be increased on the first day of each fiscal year ending on July 1, 2017, by the lesser of (i) 970,500 shares, (ii) 5% of the outstanding common shares on such date, or (iii) a lesser amount determined by the board of directors. On July 1, 2011, the number of shares available for grant was increased by 849,353 under the 2007 Plan renewal provision.

All options granted under the Plans become exercisable over periods established at the date of grant. The option exercise price is generally not less than the estimated fair market value of the Company’s common stock at the date of grant, as determined by the Company’s management and board of directors. In addition, the Company has granted nonqualified stock options to a director outside of the Plans.

All options are fully vested. Vested options must be exercised at or within 90 days of termination to avoid forfeiture. The Company determined the fair value of options using the Black-Scholes option pricing model. The estimated fair value of options, including the effect of estimated forfeitures, was recognized as expense on a straight-line basis over the options’ vesting periods.

Stock option activity for the nine months ended March 31, 2012 is as follows:

	Number of Options(a)			Weighted Average Exercise Price
Options outstanding at June 30, 2011		3,070,999		$	10.54
Options exercised		(255,202	)	$	9.39
Options forfeited or expired		(387,987	)	$	13.11
Options outstanding at March 31, 2012		2,427,810		$	10.25

(a) Includes the effect of options granted, exercised, forfeited or expired from the 1991 Plan, 2003 Plan, 2007 Plan, and options granted outside the stock option plans described above.

10

The fair value of each restricted stock award is equal to the fair market value of the Company’s common stock at the date of grant. Vesting of restricted stock awards ranges from one to three years. The estimated fair value of restricted stock awards, including the effect of estimated forfeitures, is recognized on a straight-line basis over the restricted stock’s vesting period.

7. Texas Production Facility

Effective on September 9, 2009, the Company entered into an agreement with the Pearland Economic Development Corporation (the “PEDC”) for the construction and lease of an approximately 46,000 square foot production facility located in Pearland, Texas. The facility primarily serves as an additional manufacturing location for the Company.

The lease agreement provides that the PEDC will lease the facility and the land immediately surrounding the facility to the Company for an initial term of ten years, which began April 1, 2010. Monthly fixed rent payments are $35 for each of the first five years of the initial term and $38 for each of the last five years of the initial term. The Company is also responsible for paying the taxes and operating expenses related to the facility. The lease has been classified as an operating lease for financial statement purposes. Upon an event of default under the agreement, the Company will be liable for the difference between the balance of the rent owed for the remainder of the term and the fair market rental value of the leased premises for such period.

The Company has the option to renew the lease for up to two additional periods of five years each. If the Company elects to exercise one or both of these options, the rent for such extended terms will be set at the prevailing market rental rates at such times, as determined in the agreement. After the commencement date and until shortly before the tenth anniversary of the commencement date, the Company will have the option to purchase all, but not less than all, of the leased premises at fair market value, as determined in the agreement. Further, within six years of the commencement date and subject to certain conditions, the Company has options to cause the PEDC to make two additions or expansions to the facility of a minimum of 34,000 and 45,000 square feet each.

The Company and the PEDC previously entered into a Corporate Job Creation Agreement dated June 17, 2009 (the “Job Creation Agreement”). The Job Creation Agreement provided the Company with $2,975 in net cash incentive funds. The Company believes it will be able to comply with the conditions specified in the Job Creation Agreement. The PEDC will provide the Company with an additional $1,700 of net cash incentive funds in the following amounts and upon achievement of the following milestones:

• $1,020, upon the hiring of the 75^th full-time employee at the facility; and

• $680, upon the hiring of the 125^th full-time employee at the facility.

In order to retain all of the cash incentives, beginning one year and 90 days after the commencement date, the Company must not have a planned reduction in the number of employees, resulting in fewer than 25 full-time employees at the facility for more than 120 consecutive days. Failure to meet this requirement will result in an obligation to make reimbursement payments to the PEDC as outlined in the agreement. The Company will not have any reimbursement requirements after 60 months from the effective date of the agreement. As of March 31, 2012, the Company was in compliance with all minimum requirements under the agreement.

The Job Creation Agreement also provides the Company with a net $1,275 award, of which $510 will be funded by a grant from the State of Texas for which the Company has applied through the Texas Enterprise Fund program. As of March 31, 2012, $340 of the grant from the State of Texas has been received and the remaining $170 will be provided if the Company hires a 55^th full-time employee at the facility. The PEDC has committed, by resolution, to guarantee the full award and will make payment to the Company for the remaining $765. As of March 31, 2012, $510 of that remaining $765 has been received. The grant from the State of Texas is subject to reimbursement if the Company fails to meet certain job creation targets through 2014 and maintain these positions through 2020.

11

The Company has presented the net cash incentive funds as a current and long-term liability on the balance sheet. The liabilities will be reduced over a 60 month period and recorded as an offset to expenditures incurred using a systematic methodology that is intended to reduce the majority of the liabilities in the first 24 months of the agreement. As of March 31, 2012, $3,097 in cumulative expenses has reduced the deferred grant incentive liabilities, resulting in a remaining current liability of $784 and long-term liability of $199.

8. Commitment and Contingencies

Michael Kallok Claim

On July 18, 2011, the Company received a demand letter from legal counsel for Michael Kallok, a former officer, director and consultant to the Company, claiming that Mr. Kallok is entitled to 42,594 shares of the Company’s common stock or, alternatively, the value of those shares as of July 15, 2011, which was $611. Mr. Kallok asserts that the Company improperly deemed such shares forfeited under a restricted stock agreement with Mr. Kallok. This matter is proceeding to arbitration.

The Company is defending this claim vigorously, and believes that an adverse outcome of this dispute would not have a materially adverse effect on the Company’s business, operations, cash flows or financial condition. The Company has not recognized any expense related to the settlement of this matter as it believes an adverse outcome of this action is not probable.

(a) At March 31, 2012 and 2011, 2,433,488 and 3,176,497 warrants, respectively, were outstanding. The effect of the shares that would be issued upon exercise of these warrants has been excluded from the calculation of diluted loss per share because those shares are anti-dilutive.

(b) At March 31, 2012 and 2011, 2,427,810 and 3,196,924 stock options, respectively, were outstanding. The effect of the shares that would be issued upon exercise of these options has been excluded from the calculation of diluted loss per share because those shares are anti-dilutive.

(c) At March 31, 2012 and 2011, 363,794 and 402,641 additional shares of common stock are issuable upon the conversion of outstanding convertible debt agreements. The effect of the shares that would be issued upon conversion of these debt agreements has been excluded from the calculation of diluted loss per share because those shares are anti-dilutive.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and the related notes appearing under Item 1 of Part I. Some of the information contained in this discussion and analysis or set forth elsewhere in this quarterly report, including information with respect to our plans and strategy for our business and expected financial results, includes forward-looking statements that involve risks and uncertainties. You should review the “Risk Factors” discussed in our Form 10-K for the year ended June 30, 2011 for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

OVERVIEW

We are a medical device company focused on developing and commercializing interventional treatment systems for vascular disease. Our primary products, the Diamondback 360° PAD System (the “Diamondback 360°”), the Diamondback Predator 360° PAD System (the “Predator 360°”), and the Stealth 360° PAD System (the “Stealth 360°”) are catheter-based platforms capable of treating a broad range of plaque types in leg arteries both above and below the knee and address many of the limitations associated with existing treatment alternatives. This includes calcified lesions, which are more difficult and expensive to treat and have higher rates of adverse events and restenosis. The Stealth 360° contains additional ease of use features while maintaining a mechanism of action identical to that of the Diamondback 360° and Predator 360°. We also are pursuing approval of our products for coronary use. We refer to the Diamondback 360°, the Predator 360°, and the Stealth 360° collectively in this report as the “PAD Systems.”

We were incorporated as Replidyne, Inc. in Delaware in 2000. On February 25, 2009, Replidyne, Inc. completed its business combination with Cardiovascular Systems, Inc., a Minnesota corporation (“CSI-MN”), in accordance with the terms of the Agreement and Plan of Merger and Reorganization, dated as of November 3, 2008 (the “Merger Agreement”). Pursuant to the Merger Agreement, CSI-MN continued after the merger as the surviving corporation and a wholly-owned subsidiary of Replidyne. Replidyne changed its name to Cardiovascular Systems, Inc. (“CSI”) and CSI-MN merged with and into CSI, with CSI continuing after the merger as the surviving corporation. These transactions are referred to herein as the “merger.” Replidyne was a biopharmaceutical company focused on discovering, developing, in-licensing and commercializing anti-infective products.

At the closing of the merger, Replidyne’s net assets, as calculated pursuant to the terms of the Merger Agreement, were approximately $36.6 million as adjusted. As of immediately following the effective time of the merger, former CSI stockholders owned approximately 80.2% of the outstanding common stock of the combined company, and Replidyne stockholders owned approximately 19.8% of the outstanding common stock of the combined company.

CSI was incorporated in Minnesota in 1989. From 1989 to 1997, we engaged in research and development on several different product concepts that were later abandoned. Since 1997, we have devoted substantially all of our resources to the development of the PAD Systems.

From 2003 to 2005, we conducted numerous bench and animal tests in preparation for application submissions to the FDA. We initially focused our testing on providing a solution for coronary in-stent restenosis, but later changed the focus to peripheral artery disease, or PAD. In 2006, we obtained an investigational device exemption from the FDA to conduct our pivotal OASIS clinical trial, which was completed in January 2007. The OASIS clinical trial was a prospective 20-center study that involved 124 patients with 201 lesions.

In August 2007, the FDA granted us 510(k) clearance for the use of the Diamondback 360° as a therapy in patients with PAD. We commenced commercial introduction of the Diamondback 360° in the United States in September 2007. We were granted 510(k) clearance of the Predator 360° in March 2009 and Stealth 360° in March 2011. We market the PAD Systems in the United States through a direct sales force and expend significant capital on our sales and marketing efforts to expand our customer base and utilization per customer. We assemble at our facilities the saline infusion pump used with our Stealth 360° product and the single-use catheter used in the PAD Systems with components purchased from third-party suppliers, as well as with components manufactured in-house. The control unit and guidewires are purchased from third-party suppliers.

As of March 31, 2012, we had an accumulated deficit of $174.6 million. We expect our losses to continue but generally decline as revenue grows from continued commercialization activities, development of additional product enhancements, accumulation of clinical data on our products, and further regulatory submissions. To date, we have financed our operations primarily from the issuance of common and preferred stock, convertible promissory notes, and debt.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT JUDGMENTS AND ESTIMATES

Our management’s discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of our consolidated financial statements requires us to make estimates, assumptions and judgments that affect amounts reported in those statements. Our estimates, assumptions and judgments, including those related to revenue recognition, allowance for doubtful accounts, excess and obsolete inventory, debt conversion option, and stock-based compensation are updated as appropriate at least quarterly. We use authoritative pronouncements, our technical accounting knowledge, cumulative business experience, judgment and other factors in the selection and application of our accounting policies. While we believe that the estimates, assumptions and judgments that we use in preparing our consolidated financial statements are appropriate, these estimates, assumptions and judgments are subject to factors and uncertainties regarding their outcome. Therefore, actual results may materially differ from these estimates.

Some of our significant accounting policies require us to make subjective or complex judgments or estimates. An accounting estimate is considered to be critical if it meets both of the following criteria: (1) the estimate requires assumptions about matters that are highly uncertain at the time the accounting estimate is made, and (2) different estimates that reasonably could have been used, or changes in the estimate that are reasonably likely to occur from period to period, would have a material impact on the presentation of our financial condition, results of operations, or cash flows.

RESULTS OF OPERATIONS

The following table sets forth, for the periods indicated, our results of operations expressed as dollar amounts, and, for certain line items, the changes between the specified periods expressed as percent increases or decreases:

Comparison of Three Months Ended March 31, 2012 with Three Months Ended March 31, 2011

Revenues. Revenues increased by $1.1 million, or 5.2%, from $20.2 million for the three months ended March 31, 2011 to $21.2 million for the three months ended March 31, 2012. This increase was attributable to a $1.2 million, or 6.6%, increase in revenues generated from the sale of PAD Systems, primarily from increased average selling prices as a result of the introduction of the Stealth 360°. This increase was partially offset by the decrease in supplemental product and other revenue of $109,000, or 4.3%, primarily from the termination of a distribution agreement. Supplemental product and other revenues include our Viper product line, wires, freight & handling and distribution partner products.

Currently, all of our revenues are in the United States; however, we may potentially sell internationally in the future. We expect our revenue to increase as we continue to increase the number of physicians using the device, increase the usage per physician, introduce new and improved products, and generate clinical data.

Cost of Goods Sold. Cost of goods sold increased by $1.2 million, or 30.0%, from $3.9 million for the three months ended March 31, 2011 to $5.1 million for the three months ended March 31, 2012. Cost of goods sold represents the cost of materials, labor and overhead for single-use catheters, guidewires, control units, and other ancillary products. The increase was due to a higher mix of Stealth 360° sales, which currently carry higher unit costs due to limited initial component purchasing volumes. Also, the addition of our second manufacturing facility in Texas for future production capacity has temporarily increased production costs. We expect that

14

the gross margin will stay fairly consistent through the end of this fiscal year, and then gradually improve as Stealth 360° production increases and the Texas facility becomes more fully utilized. Quarterly fluctuations could occur based on timing of new product introductions, sales mix, pricing changes, or other unanticipated circumstances.

Selling, General and Administrative Expenses. Our selling, general and administrative expenses increased by $394,000, or 2.4%, from $16.4 million for the three months ended March 31, 2011 to $16.8 million for the three months ended March 31, 2012. The primary reason for the increase was due to additional expenses relating to the building of our sales and marketing organization and medical education training programs, partially offset by decreased stock-based compensation. Selling, general and administrative expenses for the three months ended March 31, 2012 and 2011 includes $1.0 million and $1.4 million, respectively, for stock-based compensation. We expect our selling, general and administrative expenses to increase in the future due primarily to the costs associated with expanding our sales and marketing organization to further commercialize our products, and preparation for the coronary market. Fluctuations from these expectations could occur based on the timing of expenditures.

Research and Development Expenses. Research and development expenses increased by $1.2 million, or 67.7%, from $1.8 million for the three months ended March 31, 2011 to $3.0 million for the three months ended March 31, 2012. Research and development expenses relate to specific projects to improve our products or expand into new markets, such as the development of new versions of the PAD Systems, shaft designs, crown designs, and PAD and coronary clinical trials. The increase was related to advancing the Orbit II clinical trial. Research and development expenses were favorably affected during the three months ended March 31, 2011 by a $201,000 non-recurring benefit relating to the forfeiture of stock awards. As we continue to expand our product portfolio within the market for the treatment of peripheral arteries and leverage our core technology into the coronary market, we generally expect to incur increased quarterly research and development expenses throughout the remainder of fiscal year 2012. Fluctuations from these expectations could occur based on the number of projects and studies and the timing of expenditures.

Interest and Other, net. Interest and other expense increased by $78,000, or 19.9%, from expense of $392,000 for the three months ended March 31, 2011 to expense of $470,000 for the three months ended March 31, 2012. This increase in interest and other was primarily due to an increase in interest expense as a result of an increase in the amount of outstanding debt.

Comparison of Nine Months Ended March 31, 2012 with Nine Months Ended March 31, 2011

Revenues. Revenues increased by $2.5 million, or 4.4%, from $57.1 million for the nine months ended March 31, 2011 to $59.6 million for the nine months ended March 31, 2012. This increase was attributable to a $2.7 million, or 5.5%, increase in revenue generated from the sale of PAD Systems, primarily from increased average selling prices as a result of the introduction of the Stealth 360°. Supplemental product and other revenues slightly declined by $233,000, or 3.3%, from $7.0 million for the nine months ended March 31, 2011, to $6.7 million for the nine months ended March 31, 2012, primarily from the termination of a distribution agreement. Supplemental product and other revenues include our Viper product line, wires, freight & handling and distribution partner products.

Cost of Goods Sold. Cost of goods sold increased by $2.0 million, or 16.4%, from $12.1 million for the nine months ended March 31, 2011 to $14.0 million for the nine months ended March 31, 2012. Cost of goods sold represents the cost of materials, labor and overhead for single-use catheters, guidewires, control units, and other ancillary products. The increase was due to a higher mix of Stealth 360° sales which currently carry higher unit costs due to limited initial component purchasing volumes. Also, the addition of our second manufacturing facility in Texas for future production capacity has temporarily increased production costs. Cost of goods sold for the nine months ended March 31, 2012 and 2011 includes $217,000 and $268,000, respectively, for stock-based compensation.

Selling, General and Administrative Expenses. Our selling, general and administrative expenses increased by $1.3 million, or 2.8%, from $46.6 million for the nine months ended March 31, 2011 to $47.9 million for the nine months ended March 31, 2012. The primary reason for the increase was additional expenses relating to the building of our sales and marketing organization and payments related to disputed amounts with a former vendor, partially offset by decreased stock-based compensation. Selling, general and administrative expenses for the nine months ended March 31, 2012 and 2011 includes $3.4 million and $4.5 million, respectively, for stock-based compensation.

Research and Development Expenses. Research and development expenses increased by $1.8 million, or 28.8%, from $6.3 million for the nine months ended March 31, 2011 to $8.1 million for the nine months ended March 31, 2012. Research and development expenses relate to specific projects to improve our product or expand into new markets, such as the development of new versions of the PAD Systems, shaft designs, crown designs, and PAD and coronary clinical trials. The increase was related to

15

investments in advancing the Orbit II clinical trial, along with prior year expenses being reduced by the receipt of a $488,000 grant under the Qualifying Therapeutic Discovery Project program. Research and development expenses for the nine months ended March 31, 2012 and 2011 includes $336,000 and $459,000, respectively, for stock-based compensation.

Interest and Other, net. Interest and other expense, net increased by $966,000, or 130.7%, from $739,000 for the nine months ended March 31, 2011 to $1.7 million for the nine months ended March 31, 2012. This increase in expense was primarily due to $636,000 of expense from the conversion and valuation changes of our convertible debt, compared to income of $415,000 in the prior year.

NON-GAAP FINANCIAL INFORMATION

To supplement our consolidated financial statements prepared in accordance with GAAP, our management uses a non-GAAP financial measure referred to as “Adjusted EBITDA.” The following table sets forth, for the periods indicated, a reconciliation of Adjusted EBITDA to the most comparable U.S. GAAP measure expressed as dollar amounts (in thousands):

	Nine Months Ended March 31,
	2012			2011
Loss from operations	$	(10,480	)	$	(7,903	)
Add: Stock-based compensation		3,919			5,221
Add: Depreciation and amortization		676			518
Adjusted EBITDA	$	(5,885	)	$	(2,164	)

The decline in Adjusted EBITDA of $3.7 million, or 172.0%, is primarily the result of the $2.6 million, or 32.6%, increase in the loss from operations. The loss from operations was significantly impacted by the increase in operating expenses while only being partially offset by the increase in gross profit.

Adjusted EBITDA was also impacted by a decrease in stock-based compensation and increase in depreciation and amortization. Stock-based compensation decreased $1.3 million, or 24.9%, from $5.2 million for the nine months ended March 31, 2011 to $3.9 million for the nine months ended March 31, 2012. Stock-based compensation decreased as a result of fewer grants, more forfeiture credits and shares vesting. Depreciation and amortization increased as a result of additional investment in capital equipment during the nine months ended March 31, 2012 as compared to the nine months ended March 31, 2011.

Use and Economic Substance of Non-GAAP Financial Measures Used and Usefulness of Such Non-GAAP Financial Measures to Investors

We use Adjusted EBITDA as a supplemental measure of performance and believe this measure facilitates operating performance comparisons from period to period and company to company by factoring out potential differences caused by depreciation and amortization expense and non-cash charges such as stock-based compensation. Our management uses Adjusted EBITDA to analyze the underlying trends in our business, assess the performance of our core operations, establish operational goals and forecasts that are used to allocate resources and evaluate our performance period over period and in relation to our competitors’ operating results. Additionally, our management is partially evaluated on the basis of Adjusted EBITDA when determining achievement of their incentive compensation performance targets.

We believe that presenting Adjusted EBITDA provides investors greater transparency to the information used by our management for its financial and operational decision-making and allows investors to see our results “through the eyes” of management. We also believe that providing this information better enables our investors to understand our operating performance and evaluate the methodology used by our management to evaluate and measure such performance.

The following is an explanation of each of the items that management excluded from Adjusted EBITDA and the reasons for excluding each of these individual items:

16

• Stock-based compensation expense. We exclude stock-based compensation expense from our non-GAAP financial measures primarily because such expense, while constituting an ongoing and recurring expense, is not an expense that requires cash settlement. Our management also believes that excluding this item from our non-GAAP results is useful to investors to understand the application of stock-based compensation guidance and its impact on our operational performance, liquidity and ability to make additional investments in the Company, and it allows for greater transparency to certain line items in our financial statements.

• Depreciation and amortization expense. We exclude depreciation and amortization expense from our non-GAAP financial measures primarily because such expenses, while constituting ongoing and recurring expenses, are not expenses that require cash settlement and are not used by our management to assess the core profitability of our business operations. Our management also believes that excluding these items from our non-GAAP results is useful to investors to understand our operational performance, liquidity and ability to make additional investments in the Company.

Material Limitations Associated with the Use of Non-GAAP Financial Measures and Manner in which We Compensate for these Limitations

Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for our financial results prepared in accordance with GAAP. Some of the limitations associated with our use of these non-GAAP financial measures are:

• Items such as stock-based compensation do not directly affect our cash flow position; however, such items reflect economic costs to us and are not reflected in our Adjusted EBITDA and therefore these non-GAAP measures do not reflect the full economic effect of these items.

• Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles and therefore other companies may calculate similarly titled non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes.

• Our management exercises judgment in determining which types of charges or other items should be excluded from the non-GAAP financial measures we use.

We compensate for these limitations by relying primarily upon our GAAP results and using non-GAAP financial measures only supplementally.

LIQUIDITY AND CAPITAL RESOURCES

We had cash and cash equivalents of $22.5 million and $21.2 million at March 31, 2012 and June 30, 2011, respectively. During the nine months ended March 31, 2012, net cash used in operations was $8.5 million. As of March 31, 2012, we had an accumulated deficit of $174.6 million. We have historically funded our operating losses primarily from the issuance of common and preferred stock, convertible promissory notes, and debt.

Loan and Security Agreement with Silicon Valley Bank

On March 29, 2010, we entered into an amended and restated loan and security agreement with Silicon Valley Bank. The agreement was amended on December 27, 2011. The agreement, as amended, includes a $12.0 million term loan and a $15.0 million line of credit. The terms of each of these loans are as follows:

• The $12.0 million term loan has an initial interest rate of 8.0%, which can be reduced to 7.0% based on the achievement of positive EBITDA for the trailing six month period. The term loan has a 36 month maturity, with repayment terms that include interest only payments during the first six months, followed by 30 equal principal payments of $400,000 plus interest, and a final payment of $100,000 due at maturity. This term loan also includes an acceleration provision that requires us to pay the entire outstanding balance, plus a penalty ranging from 1.0% to 3.0% of the principal amount, upon prepayment or the occurrence and continuance of an event of default. The balance outstanding on the term loan at March 31, 2012 was $11.6 million. The unamortized discount associated with warrants issued to Silicon Valley Bank in connection with the loan and other fees paid to the lender will be amortized over the 36 month maturity period. This amendment is being accounted for as a debt modification.

• The $15.0 million line of credit expires on March 31, 2014 and has a floating interest rate equal to Silicon Valley Bank’s prime rate, plus 2.0%, with an interest rate floor of 6.0%. Interest on borrowings is due monthly and the principal balance is due at maturity. Borrowings on the line of credit are based on (a) 80% of eligible domestic receivables, plus (b) the lesser

17

of 40% of eligible inventory or 25% of eligible domestic receivables or $2.5 million, minus (c) to the extent in effect, certain loan reserves as defined in the agreement. Accounts receivable receipts are deposited into a lockbox account in the name of Silicon Valley Bank. The line of credit is subject to non-use fees, annual fees, and cancellation fees. The agreement provides that upon the achievement of certain financial covenants, the amount reducing available borrowings will be zero, however, if certain financial covenants are not met, 75% of the outstanding principal balance of the $12.0 million term loan reduces available borrowings under the line of credit. There was not an outstanding balance on the line of credit at March 31, 2012.

Borrowings from Silicon Valley Bank are secured by all of our assets. The borrowings are subject to prepayment penalties and financial covenants, including maintaining certain liquidity and fixed charge coverage ratios, and certain three-month EBITDA targets. We were in compliance with all financial covenants as of March 31, 2012. The agreement also includes subjective acceleration clauses which permit Silicon Valley Bank to accelerate the due date under certain circumstances, including, but not limited to, material adverse effects on our financial status or otherwise. Any non-compliance by us under the terms of debt arrangements could result in an event of default under the Silicon Valley Bank loan, which, if not cured, could result in the acceleration of this debt.

In connection with and as additional consideration for entering into the amendment to the amended and restated loan agreement with Silicon Valley Bank on December 27, 2011, we issued a warrant to purchase 12,760 shares of our common stock to Silicon Valley Bank, which warrant Silicon Valley Bank immediately transferred to its parent company, SVB Financial Group. The warrant’s exercise price was set at $9.796 per share, which price was based on the five-day average closing share price of the Company’s common stock prior to the date of the amendment. The warrant expires on the tenth anniversary of the issue date, subject to earlier expiration in accordance with its terms. In connection with entering into the amendment to the loan and security agreement with Partners for Growth III, L.P., as amended, on December 27, 2011, we issued one warrant to purchase 24,900 shares of our common stock to Silicon Valley Bank. The warrant expires on the fifth anniversary of the issue date, subject to earlier expiration in accordance with its terms, and the exercise price for the warrant was set at $9.33 per share.

Loan and Security Agreement with Partners for Growth

On April 14, 2010, we entered into a loan and security agreement with Partners for Growth III, L.P. (PFG). The agreement provides that PFG will make loans to us up to $4.0 million. The agreement has a maturity date of April 14, 2015. The loans bear interest at a floating per annum rate equal to 2.75% above Silicon Valley Bank’s prime rate, and such interest is payable monthly. The principal balance of and any accrued and unpaid interest on any notes are due on the maturity date and may not be prepaid by us at any time in whole or in part. On August 23, 2011, the loan and security agreement was amended to provide that PFG will make loans to us up to $5.0 million. All other terms of the original agreement remain the same. On December 27, 2011, the loan and security agreement, as amended, was amended to raise the total amount of indebtedness that the Company may accrue under the term loan portion of the amended and restated loan and security agreement with Silicon Valley Bank, as amended, from $10.0 million to $12.0 million.

As of March 31, 2012, PFG has provided us the following three loans totaling $5.0 million that are outstanding: (i) a $3.5 million loan dated June 30, 2011 with a conversion price of $13.64, (ii) a $500,000 loan dated August 4, 2011, as amended and restated August 24, 2011, with a conversion price of $15.30, and (iii) a $1.0 million loan dated August 24, 2011 with a conversion price of $13.42. At any time prior to the maturity date, PFG may at its option convert any of the outstanding loans into shares of our common stock at the applicable conversion price, which in each case equaled the ten-day volume weighted average price per share of our common stock prior to the issuance date of each note. We may also effect at any time a mandatory conversion of amounts, subject to certain terms, conditions and limitations provided in the agreement, including a requirement that the ten-day volume weighted average price of our common stock prior to the date of conversion is at least 15% greater than the conversion price. We may reduce the conversion price to a price that represents a 15% discount to the ten-day volume weighted average price of our common stock to satisfy this condition and effect a mandatory conversion. During the nine months ended March 31, 2012, PFG, at its option, converted a $500,000 loan (at par) into 40,323 shares of our common stock in accordance with the conversion terms set forth in the agreement. We have reflected a net expense of $636,000 for the nine months ended March 31, 2012 as a component of interest and other, net on the accompanying statement of operations, which represents the net effect of (i) the write-off of the conversion option on the converted loan, (ii) the write-off of the unamortized debt premium on the converted loan and (iii) the change in fair value of the conversion options on all outstanding loans. The balance outstanding under the loan and security agreement at March 31, 2012 was $5.6 million. The net unamortized premium associated with warrants issued to PFG in connection with the loan, a beneficial conversion feature, and other fees paid to the lender will be amortized over the remaining maturity period.

18

The loans are secured by certain of our assets, and the agreement contains customary covenants limiting the our ability to, among other things, incur debt or liens, make certain investments and loans, effect certain redemptions of and declare and pay certain dividends on its stock, permit or suffer certain change of control transactions, dispose of collateral, or change the nature of its business. In addition, the PFG loan and security agreement contains financial covenants requiring us to maintain certain liquidity and fixed charge coverage ratios, and certain three-month EBITDA targets. We were in compliance with all financial covenants at March 31, 2012. If we do not comply with the various covenants, PFG may, subject to various customary cure rights, decline to provide additional loans, require amortization of the loan over its remaining term, or require the immediate payment of all amounts outstanding under the loan and foreclose on any or all collateral, depending on which financial covenants are not maintained.

In connection with and as additional consideration for entering into the amendment to the loan and security agreement with PFG, as amended, on December 27, 2011, we issued one warrant to purchase 23,151 shares of our common stock to PFG and one warrant to purchase 3,396 shares of our common stock to PFG Equity Investors, LLC, an affiliate of PFG. Each warrant expires on the fifth anniversary of the issue date, subject to earlier expiration in accordance with its terms, and the exercise price for each of the warrants was set at $9.33 per share.

Cash and Cash Equivalents.Cash and cash equivalents were $22.5 million at March 31, 2012 and $21.2 million at June 30, 2011. The increase is primarily attributable to net cash provided by financing activities during the nine months ended March 31, 2012.

Operating Activities.Net cash used in operating activities was $8.5 million and $7.2 million for the nine months ended March 31, 2012 and 2011, respectively. For the nine months ended March 31, 2012 and 2011, we had a net loss of $12.2 million and $8.6 million, respectively. Significant adjustments to reconcile net loss to net cash used in operations and changes in working capital during these periods included:

• Depreciation and amortization of property and equipment of $636,000 and $476,000 during the nine months ended March 31, 2012 and 2011, respectively. The increase in depreciation and amortization of property and equipment is due to additional investment in property and equipment, primarily at the Texas facility.

• Debt conversion and valuation of conversion options, net, of $589,000 and $(422,000) during the nine months ended March 31, 2012 and 2011, respectively. The increase in cash provided by debt conversion and valuation of conversion options, net, is a result of the change in the fair value of the conversion option, and net write-offs upon conversion.

• Stock-based compensation of $3.9 million and $5.2 million during the nine months ended March 31, 2012 and 2011, respectively. The decrease in stock-based compensation is a result of fewer grants, more forfeiture credits and fewer unvested shares outstanding.

• Cash provided by (used in) accounts receivable of $294,000 and $(4.0) million during the nine months ended March 31, 2012 and 2011, respectively. For the nine months ended March 31, 2012, the cash provided by accounts receivable was primarily due to timing and amount of revenues. For the nine months ended March 31, 2011, cash (used in) accounts receivable was primarily due to timing and amount of revenues, and a receivable of $510,000 representing additional grants for the Texas facility.

• Cash (used in) inventories of $(2.0) million and $(546,000) during the nine months ended March 31, 2012 and 2011, respectively. For the nine months ended March 31, 2012, cash used in inventories was primarily due to the addition of the Stealth 360° product line and expansion of the Asahi wire product line, along with the timing of inventory purchases and sales.

• Cash (used in) provided by accounts payable of $(109,000) and $1.1 million during the nine months ended March 31, 2012 and 2011, respectively. For the nine months ended March 31, 2012 and March 31, 2011, cash (used in) provided by accounts payable was due to timing of purchases and vendor payments.

• Cash provided by (used in) accrued expenses and other liabilities of $71,000 and $(1.1) million during the nine months ended March 31, 2012 and 2011, respectively. For both periods, cash (used in) provided by accrued expenses and other liabilities were primarily due to amount and timing of payments.

Investing Activities. Net cash (used in) investing activities was $(895,000) and $(1.3) million for the nine months ended March 31, 2012 and 2011, respectively. For the nine months ended March 31, 2012 and 2011, cash used in investing activities entirely related to the purchase of property and equipment and patents.

19

Financing Activities. Net cash provided by financing activities was $10.7 million in the nine months ended March 31, 2012.

Cash provided by financing activities in this period included:

• Exercise of stock options and warrants and proceeds related to stock based compensation plans of $4.7 million.

• Proceeds from long-term debt of $7.9 million.

Cash (used in) financing activities in this period included:

• Payments of long-term debt of $1.9 million.

Financing Activities. Net cash provided by financing activities was $3.3 million in the nine months ended March 31, 2011.

Cash provided by financing activities in this period included:

• Exercise of stock options and warrants and proceeds related to stock based compensation plans of $818,000.

• Proceeds from long-term debt of $4.0 million.

Cash (used in) financing activities in this period included:

• Payments of long-term debt of $1.5 million

Our future liquidity and capital requirements will be influenced by numerous factors, including the extent and duration of future operating losses, the level and timing of future sales and expenditures, the results and scope of ongoing research and product development programs, working capital required to support our sales growth, the receipt of and time required to obtain regulatory clearances and approvals, our sales and marketing programs, the continuing acceptance of our products in the marketplace, competing technologies, and market and regulatory developments. As of March 31, 2012, we believe our current cash and cash equivalents and available debt will be sufficient to fund working capital requirements, capital expenditures and operations for at least the next 12 months; however, we may raise additional capital in the future to fund acceleration of our current growth initiatives or additional growth opportunities, if we believe it will significantly enhance our value. We intend to retain any future earnings to support operations and to finance the growth and development of our business, and we do not anticipate paying any dividends in the foreseeable future.

INFLATION

We do not believe that inflation has had a material impact on our business and operating results during the periods presented.

OFF-BALANCE SHEET ARRANGEMENTS

Since inception, we have not engaged in any off-balance sheet activities as defined in Item 303(a)(4) of Regulation S-K.

RECENT ACCOUNTING PRONOUNCEMENTS

In May 2011, the FASB issued guidance to amend the accounting and disclosure requirements on fair value measurements. The new guidance limits the highest-and-best-use measure to nonfinancial assets, permits certain financial assets and liabilities with offsetting positions in market or counterparty credit risks to be measured at a net basis, and provides guidance on the applicability of premiums and discounts. Additionally, the new guidance expands the disclosures on Level 3 inputs by requiring quantitative disclosure of the unobservable inputs and assumptions, as well as description of the valuation processes and the sensitivity of the fair value to changes in unobservable inputs. The new guidance became effective for us beginning January 1, 2012. Other than requiring additional disclosures, there was no material impact on our consolidated financial statements upon adoption.

20

In June 2011, the FASB issued guidance requiring that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In the two-statement approach, the first statement should present total net income and its components followed consecutively by a second statement that should present total other comprehensive income, the components of other comprehensive income, and the total of comprehensive income. The new guidance will be effective for us beginning July 1, 2012. Other than requiring additional disclosures, we do not anticipate material impacts on our consolidated financial statements upon adoption as we have no other comprehensive income.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activities is to preserve our capital for the purpose of funding operations while at the same time maximizing the income we receive from our investments without significantly increasing risk or decreasing availability. To achieve these objectives, our investment policy allows us to maintain a portfolio of cash equivalents and investments in a variety of marketable securities, including money market funds, U.S. government securities, and certain bank obligations. Our cash and cash equivalents as of March 31, 2012 include liquid money market accounts. Due to the short-term nature of these investments, we believe that there is no material exposure to interest rate risk.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer, referred to collectively herein as the Certifying Officers, are responsible for establishing and maintaining our disclosure controls and procedures. The Certifying Officers have reviewed and evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934 (the “Exchange Act”)) as of March 31, 2012. Based on that review and evaluation, which included inquiries made to certain other employees of the Company, the Certifying Officers have concluded that, as of the end of the period covered by this Report, the Company’s disclosure controls and procedures, as designed and implemented, are effective.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended March 31, 2012 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

Refer to Part I, Item 3 (Legal Proceedings) of the Company’s Annual Report on Form 10-K for the year ended June 30, 2011.

As provided in Part I, Item 3 to our annual report on Form 10-K for the year ended June 30, 2011, the sole heir to the estate of Dr. Leonid Shturman, his wife, Lela Nadirashvili (“Mrs. Shturman”), filed a writ to dismiss our patent lawsuit in Switzerland based on res judicata and collateral estoppel (the “First Complaint”). On August 24, 2011, Mrs. Shturman filed a claim against us in the U.S. District Court in Minnesota (the “Court”) seeking a declaration that she is the true owner of certain counterweight patent applications, as well as compensation for wrongful actions she alleges we perpetrated against her and harm resulting from our alleged wrongful actions (the “Second Complaint”). We filed a motion to dismiss the Second Complaint on October 20, 2011. In December 2011, the Court dismissed the First and Second Complaints. The Court found that it did not have jurisdiction over the First and Second Complaints and did not address the merits of the claims. In February 2012, Mrs. Shturman re-filed her lawsuit in Hennepin County District Court. We removed the lawsuit to federal court and filed claims seeking to correct inventorship of the two patents that had issued at that time. Mrs. Shturman has indicated that a settlement proposal is forthcoming. In December 2011, Mrs. Shturman abandoned two patent applications in the United States Patent and Trademark Office related to the counterweight technology. We have filed a continuation application to take over these applications as co-inventors. In our Switzerland action, the judge ruled in our favor regarding Mrs. Shturman’s motion to dismiss on grounds of res judicata. The matter is currently awaiting decision in the Federal Patent Court.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, including the important information in the section entitled “Private Securities Litigation Reform Act,” you should carefully consider the “Risk Factors” discussed in our Form 10-K for the year ended June 30, 2011 for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in this report, and materially adversely affect our financial condition or future results. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial might materially adversely affect our actual business, financial condition and/or operating results.
