EnteroMedics Inc. (the Company) develops and sells implantable systems to treat obesity, metabolic diseases and other gastrointestinal disorders. The Company was incorporated in the state of Minnesota on December 19, 2002 and was reincorporated in Delaware on July 22, 2004. The Company is headquartered in St. Paul, Minnesota. In January 2006, the Company established EnteroMedics Europe Sárl, a wholly-owned subsidiary located in Switzerland.

The Company’s board of directors and stockholders approved a 1-for-15 reverse split (the Reverse Stock Split) of the Company’s outstanding common stock that became effective after trading on January 6, 2016. The Reverse Stock Split did not change the par value of the Company’s stock or the number of preferred shares authorized by the Company’s Fifth Amended and Restated Certificate of Incorporation. An amendment to the Certificate of Incorporation was also approved in connection with the Reverse Stock Split to increase the number of shares of the Company’s common stock authorized for issuance to 150 million shares, effective immediately after the Reverse Stock Split on January 6, 2016. All share and per share amounts have been retroactively adjusted to reflect the Reverse Stock Split for all periods presented.

The Company is focused on the design and development of medical devices that use neuroblocking technology to treat obesity, metabolic diseases and other gastrointestinal disorders and currently has approvals to commercially launch the Maestro Rechargeable System in the United States and in Australia, the European Economic Area and other countries that recognize the European CE Mark. The Company has devoted substantially all of its resources to recruiting personnel, developing its product technology, obtaining patents to protect its intellectual property and raising capital, and has recently commenced commercial operations in the United States deriving revenues from its primary business activity in 2015.

The Company’s products require approval from the U.S. Food and Drug Administration (FDA) or corresponding foreign regulatory agencies prior to commercial sales. The Company received FDA approval on January 14, 2015 for vBloc Therapy, delivered via the Maestro Rechargeable System, and has begun a controlled commercial launch at select centers in the United States. The Maestro Rechargeable System has also received CE Mark and is listed on the Australian Register of Therapeutic Goods (ARTG).

The medical device industry is characterized by frequent and extensive litigation and administrative proceedings over patent and other intellectual property rights. Whether a product infringes a patent involves complex legal and factual issues, the determination of which is often difficult to predict, and the outcome may be uncertain until the court has entered final judgment and all appeals are exhausted. The Company’s competitors may assert that its products or the use of the Company’s products are covered by U.S. or foreign patents held by them.

The Company’s activities are subject to significant risks and uncertainties, including the ability to obtain additional financing, and there can be no assurance that the Company will be successful in obtaining additional financing on favorable terms, or at all. If adequate funds are not available, the Company may have to delay development or commercialization of products or license to third parties the rights to commercialize products or technologies that the Company would otherwise seek to commercialize.

The Company has prepared the accompanying condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. The Company’s fiscal year ends on December 31.

The accompanying condensed consolidated financial statements and notes thereto are unaudited. In the opinion of the Company’s management, these statements include all adjustments, which are of a normal recurring nature, necessary to present a fair presentation. Interim results are not necessarily indicative of results for a full year. The condensed consolidated balance sheet as of December 31, 2015 was derived from audited consolidated financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. The information included in this Form 10-Q should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.

The preparation of 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 amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All intercompany transactions and accounts have been eliminated in consolidation.

Carrying amounts of certain of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued liabilities approximate fair value due to their short maturities. The Company’s common stock warrants are required to be reported at fair value and the Company has elected to report its senior amortizing convertible notes at fair value. The fair values of common stock warrants and investments in debt and equity securities, if any, are disclosed in Note 3. The fair value of the Company’s senior amortizing convertible notes is disclosed in Notes 3 and 7.

Common stock warrants that were issued in connection with the July 8, 2015 public offering and the November 9, 2015, January 11, 2016 and May 2, 2016 senior amortizing convertible notes are classified as a liability in the condensed consolidated balance sheets, as the common stock warrants issued provide for certain anti-dilution protections in the event shares of common stock or securities convertible into shares of common stock are issued below the then-existing exercise price. The fair value of these common stock warrants is re-measured at each financial reporting period and immediately before exercise, with any changes in fair value being recognized as a component of other income (expense) in the condensed consolidated statements of operations.

The Company considers highly liquid investments generally with maturities of 90 days or less when purchased to be cash equivalents. Cash equivalents are stated at cost, which approximates market value. The Company’s cash equivalents are primarily in money market funds and certificates of deposit. The Company deposits its cash and cash equivalents in high-quality credit institutions.

The Company considers all investments with maturities greater than three months and less than one year at the time of purchase as short-term investments and classifies them as either available for sale or held to maturity. The Company also considers certain investments with maturities greater than one year but which are also held for liquidity purposes and are available for sale as short-term investments.

Available-for-sale securities are carried at fair value based on quoted market prices, with the unrealized gains and losses included in other comprehensive income within stockholders’ equity in the condensed consolidated balance sheets. Realized gains and losses and declines in value judged to be other than temporary on available-for-sale securities are included in interest and other income. Interest and dividends on securities classified as available for sale are included in interest income. The cost of securities sold is based on the specific identification method.

Short-term investments in debt securities which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for premiums and discounts that are recognized in interest income, using the interest method, over the period to maturity. Unrealized losses on held-to-maturity securities reflecting a decline in value determined to be other than temporary are charged to income.

The Company accounts for inventory at the lower of cost or market and records any long-term inventory as other assets in the condensed consolidated balance sheets.

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation of property and equipment is computed using the straight-line method over their estimated useful lives of five to seven years for furniture and equipment and three to five years for computer hardware and software. Leasehold improvements are amortized on a straight-line basis over the lesser of their useful life or the term of the lease. Upon retirement or sale, the cost and related accumulated depreciation or amortization are removed from the condensed consolidated balance sheets and the resulting gain or loss is reflected in the condensed consolidated statements of operations. Repairs and maintenance are expensed as incurred.

The Company evaluates its long-lived assets for impairment by comparison of the carrying amounts to future net undiscounted cash flows expected to be generated by such assets when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Should an impairment exist, the impairment loss would be measured based on the excess carrying value of the asset over the asset’s fair value or estimates of future discounted cash flows. The Company has not identified any such impairment losses to date.

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance for deferred income tax assets is recorded when it is more likely than not that some portion or all of the deferred income tax assets will not be realized. The Company has provided a full valuation allowance against the gross deferred tax assets. The Company’s policy is to classify interest and penalties related to income taxes as income tax expense in the condensed consolidated statements of operations.

On January 14, 2015, the Company received FDA approval for vBloc Therapy, delivered via the Maestro Rechargeable System, and starting in the second quarter of 2015 revenues were generated from sales in the United States. As a result, the Company is now required to pay a quarterly Medical Device Tax which is a part of the Affordable Care Act, which imposes a 2.3% excise tax on the sale of certain medical devices by device manufactures, producers or importers. The excise tax was effective on sales of devices made after December 31, 2012. The Company records the Medical Device Tax as an operating expense in the condensed consolidated statements of operations. A moratorium was placed on the Medical Device Tax for 2016 and 2017.

Comprehensive loss is defined as the change in equity of a company during a period from transactions and other events and circumstances excluding transactions resulting from investment owners and distributions to owners. There was no difference from reported net loss for the three and six months ended June 30, 2016 and 2015.

Revenue is recognized when persuasive evidence of an arrangement exists, title or risk of loss has passed, the selling price is fixed or determinable and collection is reasonably assured. Products are sold through direct sales or medical device distributors and revenue is recognized upon sale to a bariatric center of excellence or a medical device distributor when no right of return or price protection exists. Terms of sales to international distributors are generally EXW, reflecting that goods are shipped “ex works,” in which risk of loss is assumed by the distributor at the shipping point. A provision for returns is recorded only if product sales provide for a right of return. No provision for returns was recorded for the three and six months ended June 30, 2016 and 2015, as the product sales recorded did not provide for rights of return.

Research and development expenses are charged to expense as incurred. Research and development expenses include, but are not limited to, product development, clinical trial expenses, including supplies, devices, explants and revisions, quality assurance, regulatory expenses, payroll and other personnel expenses, materials and consulting costs.

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is based on the weighted-average common shares outstanding during the period plus dilutive potential common shares calculated using the treasury stock method. Such potentially dilutive shares are excluded when the effect would be to reduce a net loss per share. The Company’s potential dilutive shares, which include outstanding common stock options and warrants, have not been included in the computation of diluted net loss per share for all periods as the result would be anti-dilutive.

The following table sets forth the computation of basic and diluted net loss per share for the three and six months ended June 30, 2016 and 2015:

The following table sets forth the potential shares of common stock that are not included in the calculation of diluted net loss per share because to do so would be anti-dilutive as of the end of each period presented:

In March 2016, the Financial Accounting Standards Board (FASB) issued Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (Accounting Standards Update No. 2016-09 (ASU 2016-09)). ASU 2016-09 modifies several aspects of the accounting for share-based payment awards, including income tax consequences, and classification on the statement of cash flows. This guidance will be effective for interim and annual reporting periods beginning after December 15, 2016. The Company is currently evaluating the impact of adopting ASU 2016-09 on its consolidated financial statements.

In May 2014, FASB issued Revenue from Contracts with Customers, Topic 606 (Accounting Standards Update No. 2014-09 (ASU 2014-09)), which provides a framework for the recognition of revenue, with the objective that recognized revenues properly reflect amounts an entity is entitled to receive in exchange for goods and services. This guidance will be effective for interim and annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact of adopting ASU 2014-09 on its consolidated financial statements.

There have been no other significant changes in recent accounting pronouncements during the six months ended June 30, 2016 as compared to the recent accounting pronouncements described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.

The accompanying condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern. The Company has financed its operations to date principally through the sale of equity securities, debt financing and interest earned on investments. As of June 30, 2016, the Company had $11.5 million of cash and cash equivalents to fund its operations through 2016.

On November 4, 2015, the Company entered into a securities purchase agreement (the Purchase Agreement) with institutional investors to issue $25.0 million of senior amortizing convertible notes (the Notes) along with the accompanying warrants. $1.5 million of the Notes was funded at the first closing on November 9, 2015 (the First Closing). An additional $11.0 million of the Notes was funded at the second closing on January 11, 2016 (the Second Closing). Pursuant to two amendments to the Purchase Agreement entered into on May 2, 2016 (the First Amendment), and July 14, 2016 (the Second Amendment), $6.25 million was funded at the third closing on May 2, 2016 (The Third Closing) and the remaining amount, up to $6.25 million, will be funded at the fourth closing, which is scheduled to occur not later than December 1, 2016 (the Fourth Closing), subject to certain terms and conditions (see Note 6). Additionally, the Company has agreed that it will not, for a period of one year after the First Closing, issue any further securities, other than certain excluded securities.

The Company’s operations include plans that consider the controlled commercial launch of vBloc Therapy, delivered via the Maestro Rechargeable System, which was approved by the FDA on January 14, 2015. The Company believes that it has the ability to manage the growth of its expenditures and operations depending on the amount of available cash flows. However, the Company will ultimately need to achieve sufficient revenues from product sales and/or obtain additional debt or equity financing to support its operations.

In May 2016, the Company received written notices from the Nasdaq Stock Market Nasdaq stating that the Company was not in compliance with the following two Nasdaq listing requirements: (1) the requirement that the Company have a minimum of $2.5 million stockholders’ equity (the Stockholders’ Equity Requirement) and (2) the $1.00 minimum bid price stock price requirement (the Minimum Bid Requirement).

On July 19, 2016, the Company received a letter from Nasdaq granting the Company an extension until November 14, 2016 to regain compliance with the Stockholders’ Equity Requirement. The extension was granted based on the plan the Company submitted to Nasdaq to regain compliance with the Stockholders’ Equity Requirement through a combination of note conversions and accelerated principal amortizations and infusions of equity capital prior to the deadline.

The Company has 180 calendar days from the May 9, 2016 notice date to regain compliance with the Minimum Bid Requirement. In the event the Company does not regain compliance with this requirement, Nasdaq will provide the Company with written notification that its securities are subject to delisting. At that time, the Company may appeal the delisting determination to a Nasdaq Hearings Panel.

Alternatively, if the Company fails to regain compliance with the Minimum Bid Requirement prior to the expiration of the 180 calendar day period, the Company may be granted an additional 180 calendar days to regain compliance with the Minimum Bid Requirement if it (i) meets the continued listing requirement for market value of publicly held shares and all of the other applicable requirements for initial listing on Nasdaq other than the Minimum Bid Requirement, and (ii) provides written notice of its intention to cure the deficiency during the second compliance period by effecting a reverse stock split, if necessary.

The Company is actively monitoring its performance with respect to the Stockholders’ Equity Requirement and the Minimum Bid Requirement and will consider all available options to resolve each deficiency and regain compliance with the Nasdaq listing requirements.

Fair value of financial assets and liabilities is defined as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. A fair value hierarchy has been established that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

The Company’s assets that are measured at fair value on a recurring basis are classified within Level 1 or Level 2 of the fair value hierarchy. The Company does not hold any assets that are measured at fair value using Level 3 inputs. The types of instruments the Company invests in that are valued based on quoted market prices in active markets may include U.S. treasury securities and money market funds. Such instruments are classified by the company within Level 1 of the fair value hierarchy. U.S. treasuries are valued using unadjusted quoted prices for identical assets in active markets that the Company can access.

The types of instruments the Company invests in that are valued based on quoted prices in less active markets, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency include the Company’s U.S. agency securities, commercial paper, U.S. corporate bonds and municipal obligations. Such instruments are classified by the Company within Level 2 of the fair value hierarchy. The Company values these types of assets using consensus pricing or a weighted average price, which is based on multiple pricing sources received from a variety of industry standard data providers (e.g. Bloomberg), security master files from large financial institutions, and other third-party sources. The multiple prices obtained are then used as inputs into a distribution-curve-based algorithm to determine the daily market price.

The Company did not hold any short-term investments classified as available for sale or held to maturity as of June 30, 2016 and December 31, 2015.

The fair value of the Company’s common stock warrant liability is calculated using a Black-Scholes valuation model and is classified as Level 2 in the fair value hierarchy. The common stock warrants issued July 8, 2015 had a fair value of $352,206 and $2,759,583 on June 30, 2016 and December 31, 2015, respectively. The common stock warrants issued November 9, 2015 had a fair value of $15,442 and $118,234 on June 30, 2016 and December 31, 2015, respectively. The common stock warrants issued January 11, 2016 had a fair value of $54,125 and $515,157 on June 30, 2016 and January 11, 2016, respectively. The common stock warrants issued May 2, 2016 had a fair value of $32,883 and $150,195 on June 30, 2016 and May 2, 2016, respectively. The fair value was calculated using the following assumptions:

The following table summarizes fair value measurements of the Notes and the common stock warrants issued in 2015 and during the six months ended June 30, 2016 by level at June 30, 2016:

Through June 30, 2016, the Company had converted $3.2 million of the Notes’ principal and interest into shares of common stock. For the three month and six month periods ended June 30, 2016, respectively, there were gains of $1.2 million and $709,000 recognized in the condensed consolidated statements of operations from changes in fair value of the Notes.

On June 30, 2016 and December 31, 2015, the fair value of the outstanding Notes from the First Closing was determined to be $942,000 and $1.3 million, respectively. On June 30, 2016 and January 11, 2016, the fair value of the outstanding Notes from the Second Closing was determined to be $7.9 million and $9.9 million, respectively. On June 30, 2016 and May 2, 2016, the fair value of the outstanding Notes from the Third Closing was determined to be $5.5 million and $6.0 million, respectively. The fair values were calculated using a Binomial Lattice model and the following assumptions:

From the Company’s inception, inventory related purchases had been used for research and development related activities and had accordingly been expensed as incurred. In December 2011, the Company began receiving ARTG listings for components of the Maestro Rechargeable System from the Australian Therapeutic Goods Administration, with the final components being listed on the ARTG in January 2012. As a result, the Company determined certain assets were recoverable as inventory beginning in December 2011. The Company accounts for inventory at the lower of cost or market and records any long-term inventory as other assets in the condensed consolidated balance sheets. There was approximately $609,000 and $519,000 of long-term inventory, primarily consisting of raw materials, as of June 30, 2016 and December 31, 2015, respectively.

The Company rents its office, warehouse and laboratory facilities under an operating lease, which was originally set to expire on September 30, 2015. On August 25, 2015, the Company entered into an amendment extending the term of the operating lease for three years until September 30, 2018, with monthly base rent ranging from $18,925 to $20,345. Total rent expense recognized for each of the three month periods ended June 30, 2016 and 2015 was $58,905 and $67,718, and for each of the six month periods ended June 30, 2016 and 2015 was $117,810 and $135,436.. At June 30, 2016, future minimum payments under the lease are as follows:

The Company is exposed to product liability claims that are inherent in the testing, production, marketing and sale of medical devices. Management believes any losses that may occur from these matters are adequately covered by insurance, and the ultimate outcome of these matters will not have a material effect on the Company’s financial position or results of operations. The Company is not currently a party to any litigation and is not aware of any pending or threatened litigation that could have a material adverse effect on the Company’s business, operating results or financial condition.

The Company is evaluating the Maestro System in human clinical trials, including the EMPOWER trial and ReCharge trial. Both of these clinical trials require patients to be followed out to 60 months. The Company is required to pay for patient follow up visits only to the extent they occur. In the event a patient does not attend a follow up visit, the Company has no financial obligation. The Company is also required to pay for explants or revisions, including potential conversions of ReCharge control devices to active devices, should a patient request or be required to have one during the course of the clinical trials. The Company has no financial obligation unless an explant, revision or conversion is requested or required. Clinical trial costs are expensed as incurred.

On November 4, 2015, the Company entered into the Purchase Agreement to issue and sell to four institutional investors 7% senior amortizing convertible notes due 2017 in three separate closings. The Notes are convertible into shares of the Company’s common stock at a price equal to $4.35 per share with an aggregate principal amount of $25.0 million. Each Note was sold with a warrant to purchase a share of common stock (the Warrants) with an exercise price of $4.65 per share. The Company issued and sold Notes and Warrants for aggregate total proceeds of $12.5 million in two separate closings through March 31, 2016, and after entering into the First Amendment, which provided that the scheduled third closing would be split into two separate closings, issued and sold Notes and Warrants for aggregate total proceeds of $6.25 million in the Third Closing. The Company will issue and sell Notes and Warrants for aggregate total proceeds of up to $6.25 million in the Fourth Closing, which pursuant to the Second Amendment, is scheduled to occur no later than December 1, 2016. The Second Amendment provides that the Company may reduce the conversion price of the Notes from time to time in order to incentivize the holders of the Notes to convert their Notes into shares of the Company’s common stock. In addition, at the Fourth Closing, the holders of the Notes will be obligated to purchase at least 50% of the aggregate principal of the Notes they convert, either on a voluntary or installment conversion basis, on and after July 1, 2016, up to an aggregate principal amount of $6.25 million, although no holder will be obligated to purchase more Notes than originally scheduled in the First Amendment. Between July 1, 2016 and August 11, 2016, $2.6 million of aggregate principal amount of Notes were converted by holders of the Notes into approximately 14.1 million shares of the Company’s common stock.

The Notes are payable in monthly installments, accrue interest at a rate of 7.0% per annum from the date of issuance and will mature 24 months after the First Closing, unless converted or redeemed earlier. The Notes may be repaid, at the Company’s election, in either cash or shares of the Company’s common stock at a discount to the then-current market price. The Notes are also convertible from time to time, at the election of the holders, into shares of the Company’s common stock at an initial conversion price of $4.35 per share. The conversion price was adjusted to $1.09 per share on January 29, 2016, the 16^th trading day following the Reverse Stock Split, per the terms of the Notes.

The holder of each Note has the right to convert any portion of such Note unless the holder, together with its affiliates, beneficially owns in excess of 4.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to the conversion, as such percentage ownership is determined in accordance with the terms of the Notes. However, any holder may increase or decrease such percentage to any other percentage, but in no event above 9.99%, provided that any increase of such percentage will not be effective until 61 days after providing notice to the Company.

The Company has determined that the conversion feature in the Notes requires bifurcation and liability classification and measurement, at fair value, and requires evaluation at each reporting period. Under Accounting Standards Codification (ASC) 825,

Financial Instruments, the FASB provides an alternative to bifurcation and companies may instead elect fair value measurement for the entire instrument, including the debt and conversion feature. The Company has elected the fair value alternative in order to simplify its accounting and reporting of the Notes upon issuance. The fair value of the Warrants is recorded as a discount to the Notes and amortized to interest expense following the effective interest rate method over the term of the Notes.

The First Closing occurred on November 9, 2015. At the First Closing, the Company issued and sold Notes with an aggregate principal amount of $1.5 million, along with Warrants exercisable for 117,520 shares.

The Second Closing occurred on January 11, 2016 after the Company received approval of the offering by the Company’s stockholders and the satisfaction of certain customary closing conditions. At the Second Closing, the Company issued and sold Notes with an aggregate principal amount of $11.0 million, along with Warrants exercisable for 861,842 shares. The fair value of the Warrants issued on January 11, 2016 was determined to be $515,000 using a Black-Scholes valuation model and the following assumptions: (1) dividend yield of 0%; (2) expected volatility of 85.90%; (3) weighted average risk –free interest rate of 1.58%; and (4) expected life of 5.0 years.

The Third Closing occurred on May 2, 2016 after the Company entered into the First Amendment and satisfied certain closing conditions. At the Third Closing, the Company issued and sold Notes with an aggregate principal amount of $6.25 million, along with Warrants exercisable for 489,684 shares.

At the Fourth Closing, the Company will issue and sell Notes with an aggregate principal amount of up to $6.25 million, along with Warrants exercisable for 489,682 shares.

The following table summarizes the installment amounts and additional conversions by the holders of the Notes issued at the First Closing through June 30, 2016:

The following table summarizes the installment amounts and additional conversions by the holders of the Notes issued at the Second Closing through June 30, 2016:

The following table summarizes the installment amounts and additional conversions by the holders of the Notes issued at the Third Closing through June 30, 2016:

Each Warrant is exercisable immediately and for a period of 60 months from the date of the issuance of the Warrant. Upon the completion of the Fourth Closing, the Warrants will entitle the holders of the Warrants to purchase, in aggregate, 1,958,728 shares of the Company’s common stock, subject to certain adjustments. The Warrants were initially exercisable at an exercise price equal to $4.65, subject to adjustment on the eighteen month anniversary of issuance, and certain other adjustments. The exercise price and number of shares of common stock issuable on the exercise of the Warrants is subject to adjustment upon the issuance of any shares of common stock or securities convertible into shares of common stock below the then-existing exercise price, with certain exceptions, and in the event of any stock split, reverse stock split, recapitalization, reorganization or similar transaction. The holder of each Warrant does not have the right to exercise any portion of such Warrant if the holder, together with its affiliates, beneficially owns in excess of 4.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Warrants. However, any holder may increase or decrease such percentage to any other percentage, but in no event above 9.99%, provided that any increase of such percentage will not be effective until 61 days after providing notice to the Company.

The exercise price of the Warrants issued November 9, 2015 was reduced to $1.09 per share on January 29, 2016, the 16^th trading day following the Reverse Stock Split, per the terms of the Warrants. The exercise price of the Warrants issued January 11, 2016 and May 2, 2016 remains $4.65 per share per the terms of the Warrants. All of the Warrants issued with the Notes remain subject to adjustment on the eighteen month anniversary of issuance.

The fair value method of accounting for share-based payments is applied to all share-based payment awards issued to employees and where appropriate, nonemployees, unless another source of literature applies. When determining the measurement date of a nonemployee’s share-based payment award, the Company measures the stock options at fair value and remeasures such stock options to the current fair value until the performance date has been reached.

Based on the application of these standards, stock-based compensation expense for stock-based awards under the Company’s Amended and Restated 2003 Stock Incentive Plan (the Plan) and inducement grants for the three and six months ended June 30, 2016 and 2015 was allocated to operating expenses and employees and nonemployees as follows:

On June 27, 2016 the Company completed an option exchange offer to its employees whereby certain outstanding options to purchase shares of the Company’s common stock were tendered by employees in exchange for new options with the exercise price to be set at the then current market price of the Company’s common stock. Options to purchase 449,706 shares of the Company’s common stock, which included all the options eligible for exchange, were tendered by employees and cancelled by the Company. On the same date, options to purchase 75,819 shares of the Company’s common stock were issued with an exercise price of $0.3325 per share, which was the Company’s closing stock price on June 27, 2016. Because the fair value of the tendered options immediately before the exchange approximated the fair value of the new options granted, no additional compensation expense was recognized.

As of June 30, 2016 there was approximately $1.8 million of total unrecognized compensation costs, net of estimated forfeitures, related to employee unvested stock option awards, which are expected to be recognized over a weighted-average period of 3.26 years.

The estimated grant-date fair values of the stock options were calculated using the Black-Scholes valuation model, based on the following assumptions for the three and six months ended June 30, 2016 and 2015:

Option activity under the Plan for the six months ended June 30, 2016 was as follows:

In addition to the stock options granted pursuant to the Plan, the Company has also granted inducement stock options in connection with the appointments of (i) Dan Gladney to the position of President and Chief Executive Officer on October 28, 2015, (ii) Nick Ansari to the position of Senior Vice President (SVP) of Sales on January 6, 2016, (iii) Peter DeLange to the position of SVP of Operations and Business Development on January 18, 2016 and (iv) Paul Hickey to the position of SVP of Marketing and Reimbursement on January 18, 2016. Mr. Gladney was granted an option to purchase 516,666 shares of the Company’s common stock as an inducement grant, with an exercise price of $3.75 per share, the closing price of the Company’s common stock on October 28, 2015. Mr. Delange was granted an option to purchase 166,667 shares of the Company’s common stock as an inducement grant, with an exercise price of $1.38 per share, the closing price of the Company’s common stock on January 18, 2016. Mr. Ansari was granted an option to purchase 106,667 shares of the Company’s common stock as an inducement grant, with an exercise price of $1.31 per share, the closing price of the Company’s common stock on January 19, 2016. Mr. Hickey was granted an option to purchase 106,667 shares of the Company’s common stock as an inducement grant, with an exercise price of $1.32 per share, the closing price of the Company’s common stock on January 22, 2016. Each of the inducement grants will vest as follows: 25% of the shares will vest as of one year from the date of the officer’s employment agreement, and the remaining 75% of the shares will then vest in equal 2.0833% installments each month thereafter for 36 months. The inducement options were not eligible for the option exchange program.

On July 8, 2015, the Company closed a public offering, where it sold 2,133,333 units at an aggregate price of $7.50 per unit, for gross proceeds of $16.0 million before deducting estimated offering expenses of approximately $1.4 million, of which $532,000 was assigned to the warrants issued with each unit sold and was recognized immediately as interest expense in the condensed consolidated statements of operations as the warrants are exercisable upon issuance. Each unit consisted of: (A)(i) one share of common stock or (ii) one pre-funded Series C warrant to purchase one share of common stock at an exercise price equal to $7.50 per share (Series C Warrant); and (B) one Series A warrant to purchase one share of common stock at an exercise price initially equal to $9.00 per share (Series A Warrant). Each purchaser of a unit could elect to receive a Series C Warrant in lieu of a share of common stock. No Series C Warrants were issued.

of any shares of common stock or securities convertible into shares of common stock below the then-existing exercise price, with certain exceptions, and in the event of any stock split, reverse stock split, recapitalization, reorganization or similar transaction. The holder of the Series A Warrant does not have the right to exercise any portion of the Series A Warrant if the holder, together with its affiliates, would, subject to certain limited exceptions, beneficially own in excess of 9.99% of the Company’s common stock outstanding immediately after the exercise or 4.99% as may be elected by the purchaser.

The exercise price of the Series A Warrants issued July 8, 2015 was reduced to $2.40 per share on November 9, 2015 as a result of the issuance of the Notes and was further reduced to $1.50 per share on December 31, 2015, $0.97 per share on January 29, 2016, and $0.88 on March 30, 2016, $0.26 on June 30, 2016, and $0.19 on August 1, 2016 after installment payments on the Notes were made.

On June 13, 2014, the Company entered into a sales agreement with Cowen and Company, LLC (Cowen) to sell shares of the Company’s common stock having aggregate gross sales proceeds of up to $25.0 million, from time to time, through an “at-the-market” equity offering program under which Cowen will act as the Company’s sales agent (the Cowen ATM). The Company will determine, at its sole discretion, the timing and number of shares to be sold under the Cowen ATM. The Company will pay Cowen a commission for its services in acting as agent in the sale of common stock equal to 3.0% of the gross sales price per share of all shares sold through it as agent under the sales agreement. As of June 30, 2016, the Company had sold 367,903 shares under the Cowen ATM at a weighted-average selling price of $20.60 per share for gross proceeds of $7.6 million before deducting offering expenses. There have been no shares sold under the Cowen ATM subsequent to June 30, 2016 through August 11, 2016. The Company is restricted from issuing shares under the Cowen ATM until November 9, 2016 per the terms of the Purchase Agreement (see Notes 2 and 7).

We are a medical device company with approvals to commercially launch our product, the Maestro Rechargeable System, in the United States, Australia, the European Economic Area and other countries that recognize the European CE Mark. We are focused on the design and development of devices that use neuroblocking technology to treat obesity, metabolic diseases and other gastrointestinal disorders. Our proprietary neuroblocking technology, which we refer to as vBloc Therapy, is designed to intermittently block the vagus nerve using high frequency, low energy, electrical impulses. We have a limited operating history and only recently received U.S. Food and Drug Administration (FDA) approval to sell our product in the United States. In addition, we have regulatory approval to sell our product in Australia, the European Economic Area and other countries that recognize the European CE Mark and do not have any other source of revenue. We were incorporated in Minnesota on December 19, 2002 and later reincorporated in Delaware on July 22, 2004. We have devoted substantially all of our resources to the development and commercialization of the Maestro Rechargeable System.

The Maestro Rechargeable System, our initial product, uses vBloc Therapy to limit the expansion of the stomach, help control hunger sensations between meals, reduce the frequency and intensity of stomach contractions and produce a feeling of early and prolonged fullness. We believe the Maestro Rechargeable System offers obese patients a minimally-invasive treatment that can result in significant, durable and sustained weight loss. We believe that our Maestro Rechargeable System allows bariatric surgeons to offer a new option to obese patients who are concerned about the risks and complications associated with currently available anatomy-altering, restrictive or malabsorptive surgical procedures.

We received FDA approval on January 14, 2015 for vBloc Therapy, delivered via the Maestro Rechargeable System, for the treatment of adult patients with obesity who have a Body Mass Index (BMI) of at least 40 to 45 kg/m2, or a BMI of at least 35 to 39.9 kg/m2 with a related health condition such as high blood pressure or high cholesterol levels, and who have tried to lose weight in a supervised weight management program and failed within the past five years. We have begun a controlled commercial launch at select centers in the United States and had our first commercial sales in 2015. During 2015, we began a controlled expansion of our commercial operations and started the process of building a sales force. In January 2016, we hired three new executives to oversee this expansion. The direct sales force is supported by field technical managers who provide training, technical and other support services to our customers. Throughout 2015, our sales force called directly on key opinion leaders and bariatric surgeons at commercially-driven centers that met our certification criteria, which led to the training and certification of over 50 centers and 75 surgeons in implanting and administering vBloc Therapy. We have continued these efforts in the first six months of 2016 and plan to build on these efforts during the remainder of 2016 through geography and self-pay patient focused direct-to-patient marketing, key opinion leader and center specific partnering, and a multi-faceted reimbursement strategy. To date, we have relied on, and anticipate that we will continue to rely on, third-party manufacturers and suppliers for the production of the Maestro Rechargeable System.

Data from our ReCharge trial was used to support the premarket approval (PMA) application for the Maestro Rechargeable System, submitted to the FDA in June 2013. The ReCharge trial is a randomized, double-blind, sham-controlled, multicenter pivotal clinical trial testing the effectiveness and safety of vBloc Therapy utilizing our Maestro Rechargeable System. All patients in the trial received an implanted device and were randomized in a 2:1 allocation to treatment or sham control groups. The sham control group received a non-functional device during the trial period. All patients were expected to participate in a standard weight management counseling program. The primary endpoints of efficacy and safety were evaluated at 12 months. As announced, the ReCharge trial met its primary safety endpoint with a 3.7% serious adverse event rate. The safety profile at 12 months was further supported by positive cardiovascular signals including a 5.5 mmHg drop in systolic blood pressure, a 2.8 mmHg drop in diastolic blood pressure and a 3.6 bpm drop in average heart rate.

Although the trial did not meet its predefined co-primary efficacy endpoints, it did demonstrate in the intent to treat (ITT) population (n=239) a clinically meaningful and statistically significant excess weight loss (EWL) of 24.4% (approximately 10% total body weight loss (TBL)) for vBloc Therapy-treated patients, with 52.5% of patients achieving at least 20% EWL. In the per protocol population, the trial demonstrated an EWL of 26.3% for vBloc Therapy-treated patients, with 56.8% of patients achieving at least 20% EWL.

In the ReCharge trial, two-thirds of vBloc Therapy-treated patients achieved at least 5% TBL at 12 months. According to the Centers for Disease Control and Prevention (CDC), 5% TBL can have significant health benefits on obesity related risk factors, or comorbidities, including reduction in blood pressure, improvements in Type 2 diabetes and reductions in triglycerides and cholesterol. Further analysis of our data at 12 months showed a meaningful impact on these comorbidities as noted in the below table showing the improvements seen at 10% TBL, the average weight loss in vBloc Therapy-treated patients.

We subsequently announced that vBloc Therapy-treated patients were maintaining their weight loss at 18 months and 24 months with an EWL of 23.5% and 21.1%, respectively. The trial’s positive safety profile also continued throughout this reported time period.

We obtained European CE Mark approval for our Maestro Rechargeable System in 2011 for the treatment of obesity. The CE Mark approval for our Maestro Rechargeable System was expanded in 2014 to also include use for the management of Type 2 diabetes in obese patients. In January 2012, the final Maestro Rechargeable System components were listed on the Australian Register of Therapeutic Goods (ARTG) by the Therapeutic Goods Administration (TGA). The costs and resources required to successfully commercialize the Maestro Rechargeable System internationally are currently beyond our capability. Accordingly, we intend to devote our near-term efforts toward mounting a successful system launch in the United States. We intend to explore select international markets to commercialize the Maestro Rechargeable System as our resources permit, using direct, dealer and distributor sales models as the targeted market best dictates.

To date, we have not observed any mortality related to our device or any unanticipated adverse device effects in our human clinical trials. We have also not observed any long-term problematic clinical side effects in any patients. In addition, data from our VBLOC-DM2 ENABLE trial outside the United States demonstrate that vBloc Therapy may hold promise in improving obesity-related comorbidities such as diabetes and hypertension. We are conducting, or plan to conduct, further studies in each of these comorbidities to assess vBloc Therapy’s potential in addressing multiple indications.

We recently commenced commercial operations in the United States, deriving revenues from our primary business activity in 2015. We expect to incur significant sales and marketing expenses prior to recording sufficient revenue to offset these expenses. We expect our selling, general and administrative expenses to increase as we continue to add the infrastructure necessary to support our initial commercial sales, operate as a public company and develop our intellectual property portfolio. For these reasons, we expect to continue to incur operating losses for the next several years. We have financed our operations to date principally through the sale of equity securities, debt financing and interest earned on investments.

Our board of directors and stockholders approved a 1-for-15 reverse split of the Company’s outstanding common stock that became effective after trading on January 6, 2016 (the Reverse Stock Split). The Reverse Stock Split did not change the par value of our stock or the number of preferred shares authorized by our Fifth Amended and Restated Certificate of Incorporation. An amendment to the Certificate of Incorporation was also approved in connection with the Reverse Stock Split to increase the number of shares of our common stock authorized for issuance to 150 million shares, effective immediately after the Reverse Stock Split on January 6, 2016. All share and per share amounts have been retroactively adjusted to reflect the Reverse Stock Split for all periods presented.

We received FDA approval on January 14, 2015 for vBloc Therapy, delivered via the Maestro Rechargeable System, and have begun a controlled commercial launch at select centers in the United States. In 2015 we trained and certified over 50 centers and 75 surgeons in implanting and administering vBloc Therapy. We had our first commercial sales within the United States in 2015 and for the year ended December 31, 2015 we recognized $292,000 in revenue. We have not generated revenue from commercial sales outside of the United States since 2012.

Any revenue from initial sales of a new product in the United States or internationally is difficult to predict and in any event will only modestly reduce our continued losses resulting from our research and development and other activities.

Our selling, general and administrative expenses consist primarily of compensation for executive, finance, market development and administrative personnel, including stock-based compensation. Other significant expenses include professional services and consulting fees, costs associated with attending medical conferences, other professional fees for legal services, including legal services associated with our efforts to obtain and maintain broad protection for the intellectual property related to our products, and accounting services, cash management fees and travel expenses.

Our research and development expenses primarily consist of engineering, product development, quality assurance and clinical and regulatory expenses, incurred in the development of our Maestro Rechargeable System. Research and development expenses also include employee compensation, including stock-based compensation, consulting services, outside services, materials, clinical trial expenses, including supplies, devices, explants and revisions, depreciation and travel. We expense research and development costs as they are incurred.

Sales. Sales were $276,000 for the three months ended June 30, 2016, compared to $79,000 sales for the three months ended June 30, 2015. The increase of $197,000 is the result of receiving FDA approval on January 14, 2015 and commencing a controlled commercial launch of the Maestro Rechargeable System at select centers in the United States which resulted in sales of 23 units during the second quarter of 2016 versus six units during the second quarter of 2015.

Cost of Goods Sold. Cost of goods sold were $155,000 for the three months ended June 30, 2016, compared to $31,000 cost of goods sold for the three months ended June 30, 2015. The expense increase was driven primarily by the 283% increase in unit sales over the prior year period. The Company’s gross margin percentage declined to 43.8% for the three months ended June 30, 2016 from 61.1% due primarily to a reduction in average sales price and, to a lesser degree, by an increase in overhead costs applied to inventory.

Selling, General and Administrative Expenses. Selling, general and administrative expenses were $5.6 million for the three months ended June 30, 2016, compared to $4.9 million for the three months ended June 30, 2015. The increase of $0.7 million, or 13.2%, was primarily due to increases of $830,000 in professional services partially offset by declines in payroll-related expenses of $272,000. The increase in professional services expenses are the result of increasing commercialization efforts after receiving FDA approval on January 14, 2015 and beginning a controlled commercial launch at select centers in the United States.

Research and Development Expenses. Research and development expenses declined to $1.2 million for the three months ended June 30, 2016 from $2.5 million for the three months ended June 30, 2015. The decrease of $1.3 million, or 51.3%, was primarily due to decreases of $272,000, $228,000, and $362,000 in payroll-related expenses, professional services expenses and supplies expenses, respectively. The decreases are the result of a shift away from a research and development focus towards commercialization following FDA approval on January 14, 2015.

Interest Expense. Interest expense was $853,000 for the three months ended June 30, 2016, compared to $60,000 for the three months ended June 30, 2015. The increase of $793,000 was driven by interest costs from the three closings of the senior amortizing convertible notes (the Notes), that occurred on November 9, 2015, January 11, 2016 and May 2, 2016, as well as approximately $277,000 in debt issuance costs expensed as interest during the second quarter of 2016.

Change in Value of Convertible Notes Payable. The value of the Notes payable declined $1.2 million during the three months ended June 30, 2016. There were no Notes outstanding for the three months ended June 30 2016 as the notes were issued November 9, 2015, January 11, 2016 and May 2, 2016. The Notes contain a conversion feature and the decline in the Company’s common stock price from $0.97 to $0.20 on June 30, 2016 was the primary driver of the reduction in the fair value of the Notes. The fair market value was calculated using a Binomial Lattice model.

Change in Value of Warrant Liability. The value of the common stock warrant liability decreased $1.3 million for the three months ended June 30, 2016. There were no warrants outstanding that were required to be measured at fair value for the six months ended June 30, 2015. Common stock warrant liabilities were recorded on July 8, 2015, November 9, 2015, January 11, 2016 and May 2, 2016, as the common stock warrants issued with the July 8, 2015 public offering and with the Notes provide for certain anti-dilution protections in the event shares of common stock or securities convertible into shares of common stock are issued below the then-existing exercise price. The fair market value was calculated using the Black-Scholes valuation model, which resulted in $846,000, $60,000, $285,000 and $117,000 decreases for the three months ended June 30, 2016 for the common stock warrants issued with the July 8, 2015 public offering, November 9, 2015 Notes, the January 11, 2016 Notes and the May 2, 2016 Notes, respectively, as our stock price decreased from $0.97 on March 31, 2016 and $0.75 on May 2, 2016 to $0.20 on June 30, 2016.

Sales. Sales were $348,000 for the six months ended June 30, 2016, compared to $79,000 sales for the six months ended June 30, 2015. The increase of $269,000 is the result of receiving FDA approval on January 14, 2015 and commencing a controlled commercial launch of the Maestro Rechargeable System at select centers in the United States which resulted in sales of 29 units during the six months ended June 30, 2016 versus six units during the comparable period from 2015.

Cost of Goods Sold. Cost of goods sold were $195,000 for the six months ended June 30, 2016, compared to $31,000 for the six months ended June 30, 2015. The expense increase was driven primarily by the 480% increase in unit sales over the prior year period. The Company’s gross margin percentage declined to 43.8% for the six months ended June 30, 2016 from 61.1% due primarily to a reduction in average sales price and, to a lesser degree, by an increase in overhead costs applied to inventory.

Selling, General and Administrative Expenses. Selling, general and administrative expenses were $11.7 million for the six months ended June 30, 2016, compared to $9.7 million for the six months ended June 30, 2015. The increase of $2.1 million, or 21.3%, was primarily due to a $2.0 million increase in professional services expenses The increase in professional services are the result of increasing commercialization efforts after receiving FDA approval on January 14, 2015 and beginning a controlled commercial launch at select centers in the United States.

Research and Development Expenses. Research and development expenses were $2.6 million for the six months ended June 30, 2016, compared to $4.7 million for the six months ended June 30, 2015. The decrease of $2.1 million or 44.0%, was primarily due to decreases of $947,000. $502,000 and $426,000 in payroll-related expenses, professional services expenses and supply expenses, respectively. The decreases are the result of a shift away from a research and development focus towards commercialization following FDA approval on January 14, 2015.

Interest Expense. Interest expense was $2.0 million for the six months ended June 30, 2016, compared to $275,000 for the six months ended June 30, 2015. The increase of $1.7 million is primarily due to the interest expense recognized during the period for the three closings of the Notes that occurred on November 9, 2015, January 11, 2016 and May 2, 2016. Additionally, approximately $960,000 of debt issuance costs were recognized in the first two quarters of 2016 as interest expense as we elected the fair value alternative for the Notes. Interest expense recognized for the six months ended June 30, 2015 included a $187,000 success fee paid to Silicon Valley Bank required by the Loan and Security Agreement as a result of achieving FDA approval on January 14, 2015.

Change in Value of Convertible Notes Payable. The value of the Notes payable declined $709,000 million during the six months ended June 30, 2016. There were no Notes outstanding for the six months ended June 30, 2016 as the Notes were issued November 9, 2015, January 11, 2016 and May 2, 2016. The Notes contain a conversion feature and the decline in the Company’s common stock price from $1.95 at December 31, 2015, $1.33 on January 11, 2016 and $0.75 at May 20, 2016 to $0.20 on June 30, 2016 was the primary driver of the reduction in the fair value of the Notes. The fair market value was calculated using a Binomial Lattice model.

Change in Value of Warrant Liability. The value of the common stock warrant liability decreased $3.1 million for the six months ended June 30, 2016, primarily due to the decrease in the market value of the Company’s common stock compared with the exercise price of warrants. There were no warrants outstanding that were required to be measured at fair value for the six months ended June 30, 2015. Common stock warrant liabilities were recorded on July 8, 2015, November 9, 2015 and January 11, 2016 as the common stock warrants issued with the July 8, 2015 public offering and with the Notes provide for certain anti-dilution protections in the event shares of common stock or securities convertible into shares of common stock are issued below the then-existing exercise price. The fair market value was calculated using the Black-Scholes valuation model, which resulted in $2.4 million, $103,000,

$461,000 and $117,000 decreases for the six months ended June 30, 2016 for the common stock warrants issued with the July 8, 2015 public offering, November 9, 2015 Notes, the January 11, 2016 Notes and the May 2, 2016 Notes, respectively, as our stock price decreased from $1.95 on December 31, 2015 and $1.33 on January 11, 2016 and $0.75 on May 2, 2016 to $0.20 on June 30, 2016.

As of June 30, 2016, we had $11.5 million in cash and cash equivalents. Of this amount $2.8 million was invested in short-term money market funds that are not considered to be bank deposits and are not insured or guaranteed by the Federal Deposit Insurance Company or other government agency. These money market funds seek to preserve the value of the investment at $1.00 per share; however, it is possible to lose money investing in these funds. Cash in excess of immediate requirements is invested in accordance with our investment policy, primarily with a view to liquidity and capital preservation. At times, such deposits may be in excess of insured limits. We have not experienced any losses on our deposits of cash and cash equivalents.

In May 2016, the Company received written notices from the Nasdaq Stock Market Nasdaq stating that the Company was not in compliance with the following two Nasdaq listing requirements: (i) the requirement that the Company have a minimum of $2.5 million stockholders’ equity (the Stockholders’ Equity Requirement) and (ii) the $1.00 minimum bid price stock price requirement (the Minimum Bid Requirement).

Alternatively, if the Company fails to regain compliance with the Minimum Bid Requirement prior to the expiration of the 180 calendar day period, the Company may be granted an additional 180 calendar days to regain compliance with the Minimum Bid Requirement if it (i) meets the continued listing requirement for market value of publicly held shares and all of the other applicable requirements for initial listing on Nasdaq other than the minimum bid price, and (ii) provides written notice of its intention to cure the deficiency during the second compliance period by effecting a reverse stock split, if necessary.

The Company intends to actively monitor its performance with respect to the Stockholders’ Equity Requirement and the Minimum Bid Requirement and will consider all available options to resolve each deficiency and regain compliance with the Nasdaq listing requirements

On June 13, 2014, we entered into a sales agreement with Cowen and Company, LLC (Cowen) to sell shares of our common stock having aggregate gross sales proceeds of up to $25.0 million, from time to time, through an “at-the-market” equity offering program under which Cowen will act as our sales agent (the Cowen ATM). We will determine, at our sole discretion, the timing and

number of shares to be sold under the Cowen ATM. We will pay Cowen a commission for its services in acting as agent in the sale of common stock equal to 3.0% of the gross sales price per share of all shares sold through it as agent under the sales agreement. As of June 30, 2016, we have sold 367,903 shares under the Cowen ATM at a weighted-average selling price of $20.60 per share for gross proceeds of $7.6 million before deducting offering expenses. There have been no shares sold under the Cowen ATM subsequent to June 30, 2016 through August 11, 2016. We are restricted from issuing shares under the Cowen ATM until November 9, 2016 per the terms of the Notes (further described below).

On July 8, 2015, we closed a public offering where we sold 2,133,333 units at an aggregate price of $7.50 per unit, for gross proceeds of $16.0 million, before deducting estimated offering expenses of approximately $1.4 million, of which $532,000 was assigned to the warrants. Each unit consisted of: (A)(i) one share of common stock or (ii) one pre-funded Series C warrant to purchase one share of common stock at an exercise price equal to $7.50 per share (Series C Warrant); and (B) one Series A warrant to purchase one share of common stock at an exercise price equal initially to $9.00 per share (Series A Warrant). Each purchaser of a unit could elect to receive a Series C Warrant in lieu of a share of common stock. No Series C Warrants were issued.

The Series A Warrants are exercisable for a period of 42 months from the closing date of the public offering. The exercise price and number of shares of common stock issuable on the exercise of the Series A Warrants are subject to adjustment upon the issuance of any shares of common stock or securities convertible into shares of common stock below the then-existing exercise price, with certain exceptions, and in the event of any stock split, reverse stock split, recapitalization, reorganization or similar transaction. The holder of the Series A Warrant does not have the right to exercise any portion of the Series A Warrant if the holder, together with its affiliates, would, subject to certain limited exceptions, beneficially own in excess of 9.99% of our common stock outstanding immediately after the exercise or 4.99% as may be elected by the purchaser.

The exercise price of the Series A Warrants issued July 8, 2015 was reduced to $2.40 per share on November 9, 2015 as a result of the issuance of the Notes and was further reduced to $1.50 per share on December 31, 2015, $0.97 per share on January 29, 2016, $0.26 on June 30, 2016, and $0.20 on August 1, 2016 after installment payments on the Notes were made.

On November 4, 2015, we entered into the Purchase Agreement to issue and sell to four institutional investors 7% senior amortizing convertible notes due 2017 in three separate closings. The Notes are convertible into shares of our common stock at a price equal to $4.35 per share with an aggregate principal amount of $25.0 million. Each Note was sold with a warrant to purchase a share of common stock (the Warrants) with an exercise price of $4.65 per share. We issued and sold Notes and Warrants for aggregate total proceeds of $12.5 million in two separate closings through March 31, 2016, and after entering into the First Amendment, which provided that the scheduled third closing would be split into two separate closings, issued and sold Notes and Warrants for aggregate total proceeds of $6.25 million in the third closing, which occurred on May 2, 2016 (the Third Closing). We will issue and sell Notes and Warrants for aggregate total proceeds of up to $6.25 million in the fourth and final closing (the Fourth Closing). Additionally, the Second Amendment provides that the Company may reduce the conversion price of the Notes from time to time in order to incentivize the holders of the Notes to convert their Notes to common shares. In addition, at the Fourth Closing, holders of the Notes will be obligated to purchase at least 50% of the aggregate principal amount of the Note amounts they convert, either on a voluntary or installment conversion basis, on and after July 1, 2016, up to an aggregate amount of $6.25 million, although no holder will be obligated to purchase more Notes than originally scheduled in the First Amendment.

The Notes are payable in monthly installments, accrue interest at a rate of 7.0% per annum from the date of issuance and will mature 24 months after the First Closing, unless converted or redeemed earlier. The Notes may be repaid, at our election, in either cash or shares of our common stock at a discount to the then-current market price. The Notes are also convertible from time to time, at the election of the holders, into shares of our common stock at an initial conversion price of $4.35 per share. The conversion price was adjusted to $1.09 per share on January 29, 2016, the 16th trading day following the Reverse Stock Split, per the terms of the Notes.

The holder of each Note has the right to convert any portion of such Note unless the holder, together with its affiliates, beneficially owns in excess of 4.99% of the number of shares of our common stock outstanding immediately after giving effect to the conversion, as such percentage ownership is determined in accordance with the terms of the Notes. However, any holder may increase or decrease such percentage to any other percentage, but in no event above 9.99%, provided that any increase of such percentage will not be effective until 61 days after providing us notice.

The First Closing occurred on November 9, 2015. At the First Closing, we issued and sold Notes with an aggregate principal amount of $1.5 million, along with Warrants exercisable for 117,520 shares.

The Second Closing occurred on January 11, 2016 after we received approval of the offering by our stockholders and the satisfaction of certain customary closing conditions. At the Second Closing, we issued and sold Notes with an aggregate principal amount of $11.0 million, along with Warrants exercisable for 861,842 shares.

The Third Closing occurred on May 2, 2016 after we entered into the First Amendment and satisfied certain closing conditions. At the Third Closing, we issued and sold Notes with an aggregate principal amount of $6.25 million, along with Warrants exercisable for 489,684 shares.

At the Fourth Closing we will issue and sell Notes with an aggregate principal amount of up to $6.25 million, along with Warrants exercisable for 489,682 shares.

The following table summarizes the installment amounts and additional conversions by the holders of the Notes issued at the First Closing through June 30, 2016:

The following table summarizes the installment amounts and additional conversions by the holders of the Notes issued at the Second Closing through June 30, 2016:

The following table summarizes the installment amounts and additional conversions by the holders of the Notes issued at the Third Closing through June 30, 2016:

Between July 1, 2016 and August 11, 2016 $2.6 million of aggregate principal amount of Notes were converted by holders of the Notes into approximately 14.1 million shares of the Company’s common stock.

Each Warrant is exercisable immediately and for a period of 60 months from the date of the issuance of the Warrant. Upon the completion of the Fourth Closing, the Warrants will entitle the holders of the Warrants to purchase, in aggregate, 1,958,728 shares of our common stock, subject to certain adjustments. The Warrants are initially exercisable at an exercise price equal to $4.65, subject to adjustment on the eighteen month anniversary of issuance, and certain other adjustments. The exercise price and number of shares of common stock issuable on the exercise of the Warrants is subject to adjustment upon the issuance of any shares of common stock or securities convertible into shares of common stock below the then-existing exercise price, with certain exceptions, and in the event of any stock split, reverse stock split, recapitalization, reorganization or similar transaction. The holder of each Warrant does not have the right to exercise any portion of such Warrant if the holder, together with its affiliates, beneficially owns in excess of 4.99% of the number of shares of the Company’s common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Warrants. However, any holder may increase or decrease such percentage to any other percentage, but in no event above 9.99%, provided that any increase of such percentage will not be effective until 61 days after providing us notice.

The exercise price of the Warrants issued November 9, 2015 was reduced to $1.09 per share on January 29, 2016, the 16th trading day following the Reverse Stock Split, per the terms of the Warrants. The exercise price of the Warrants issued January 11, 2016 and May 2, 2016 remains $4.65 per share per the terms of the Warrants. All of the Warrants issued with the Notes remain subject to adjustment on the eighteen month anniversary of issuance.

Net cash used in operating activities was $12.5 million and $11.2 million for the six months ended June 30, 2016 and 2015, respectively. Net cash used in operating activities primarily reflects the net loss for those periods, less noncash expenses for stock-based compensation, depreciation and amortization, change in value of convertible notes payable, change in value of warrant liability, and partially offset by changes in operating assets and liabilities.

Net cash used in investing activities was $12,000 and $36,000 for the six months ended June 30, 2016 and 2015, respectively. Net cash used in investing activities for the six months ended June 30, 2016 and 2015 is attributable to the purchase of property and equipment.

Net cash provided by financing activities was $16.1 million and $4.4 million for the six months ended June 30, 2016 and 2015, respectively. Net cash provided by financing activities for the six months ended June 30, 2016 was due to $17.25 million in gross proceeds from the issuance of the Notes on January 11, 2016 and May 2, 2016, offset by $727,000 of debt issuance costs and principal repayments of $405,000 on the Notes. Net cash provided by financing activities for the six months ended June 30, 2015 was due to gross proceeds from “at-the-market” program draws of $6.7 million, offset by $2.0 million in principal repayments on our long-term debt and $228,000 in financing costs.

We received FDA approval on January 14, 2015 for vBloc Therapy, delivered via the Maestro Rechargeable System, and have begun a controlled commercial launch at select centers in the United States. We had our first commercial sales within the United States in 2015 and for the year ended December 31, 2015 we recognized $292,000 in revenue. For the six months ended June 30, 2016

we recognized $348,000 in revenue. We anticipate that we will continue to incur net losses for the next several years as we develop our products, commercialize our Maestro Rechargeable System, develop the corporate infrastructure required to sell our products, operate as a publicly-traded company and pursue additional applications for our technology platform.

We have financed our operations to date principally through the sale of equity securities, debt financing and interest earned on investments. As of June 30, 2016, we had $11.5 million of cash and cash equivalents to fund our anticipated operations through 2016. On November 4, 2015 we entered into the Purchase Agreement with institutional investors to issue $25.0 million of Notes along with the accompanying Warrants. $1.5 million of the Notes was funded at the First Closing on November 9, 2015. An additional $11.0 million of the Notes was funded at the Second Closing on January 11, 2016 and $6.25 million more of the Notes was funded at the Third Closing on May 2, 2016, with the remaining $6.25 million to be funded at the Fourth Closing. Additionally, we have agreed that we will not, for a period of one year after the First Closing, issue any further securities, other than certain excluded securities. Our anticipated operations include plans that consider the controlled commercial launch of vBloc Therapy, delivered via the Maestro Rechargeable System, which was approved by the FDA on January 14, 2015. We believe that we have the flexibility to manage the growth of our expenditures and operations. In order to accelerate the execution of our business plans we may need to raise additional funds. Obtaining funds through the sale of additional equity and debt securities may result in dilution to our stockholders. If we raise additional funds through the issuance of debt securities, these securities could have rights senior to those of our common stock and could contain covenants that would restrict our operations. The sale of additional equity may require us to obtain approval from our stockholders to increase the number of shares of common stock we have authorized under our certificate of incorporation. We may require additional capital beyond our currently forecasted amounts. Any such required additional capital may not be available on reasonable terms, if at all. If we are unable to obtain additional financing, we may be required to reduce the scope of, delay, or eliminate some or all of, our planned research, development and commercialization activities, which could materially harm our business. In addition, if we raise additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to products or proprietary technologies, or grant licenses on terms that are not favorable.

Our forecast of the period of time through which our financial resources will be adequate to support our operations, the costs to complete development of products and the cost to commercialize our products are forward-looking statements and involve risks and uncertainties, and actual results could vary materially and negatively as a result of a number of factors, including the factors discussed in Part I, Item 1A, Risk Factors, of our Annual Report on Form 10-K for the year ended December 31, 2015. We have based these estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect.

Because of the numerous risks and uncertainties associated with the development of medical devices, such as our Maestro Rechargeable System, we are unable to estimate the exact amounts of capital outlays and operating expenditures necessary to complete the development of the products and successfully deliver a commercial product to the market. Our future capital requirements will depend on many factors, including, but not limited to, the following:

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States. In doing so, we have to make estimates and assumptions that affect our reported amounts of assets, liabilities and expenses, as well as related disclosure of contingent assets and liabilities. In many cases, we could reasonably have used different accounting policies and estimates. In some cases, changes in the accounting estimates are reasonably likely to occur from period to period. Accordingly, actual results could differ materially from our estimates. To the extent that there are material differences between these estimates and actual results, our financial condition or results of operations will be affected. We base our estimates on past experiences and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis.

During the six months ended June 30, 2016, there were no material changes to our significant accounting policies which are fully described in Note 2 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2015.

During the six months ended June 30, 2016, there were no material changes to our contractual obligation disclosures as set forth under the caption, “Contractual Obligations” in Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of our Annual Report on Form 10-K for the year ended December 31, 2015.

The following table summarizes our contractual obligations as of June 30, 2016 and the effect those obligations are expected to have on our financial condition and liquidity position in future periods:

The table above reflects only payment obligations that are fixed and determinable based on our current agreements. Our operating lease commitment relates to our corporate headquarters in St. Paul, Minnesota. The above table does not include the Notes due to the variability in timing and the option to settle the Notes through the issuance of shares.

In March 2016, the Financial Accounting Standards Board (FASB) issued Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (Accounting Standards Update No. 2016-09 (ASU 2016-09)). ASU 2016-09 modifies several aspects of the accounting for share-based payment awards, including income tax consequences, and classification on the statement of cash flows. This guidance will be effective for interim and annual reporting periods beginning after December 15, 2016. We are currently evaluating the impact of adopting ASU 2016-09 on our consolidated financial statements.

In May 2014, FASB issued Revenue from Contracts with Customers, Topic 606 (Accounting Standards Update No. 2014-09 (ASU 2014-09)), which provides a framework for the recognition of revenue, with the objective that recognized revenues properly reflect amounts an entity is entitled to receive in exchange for goods and services. This guidance will be effective for interim and annual reporting periods beginning after December 15, 2017. We are currently evaluating the impact of adopting ASU 2014-09 on our consolidated financial statements.

There have been no other significant changes in recent accounting pronouncements during the six months ended June 30, 2016 as compared to the recent accounting pronouncements described in our Annual Report on Form 10-K for the year ended December 31, 2015.

Our exposure to market risk is confined to our cash and cash equivalents. As of June 30, 2016, we had $11.5 million in cash and cash equivalents. The goals of our investment policy are preservation of capital, fulfillment of liquidity needs and fiduciary control of cash and investments. We also seek to maximize income from our investments without assuming significant risk. To achieve our

goals, we may maintain a portfolio of cash equivalents and investments in a variety of securities of high credit quality. The securities in our investment portfolio, if any, are not leveraged, are classified as either available for sale or held-to-maturity and are, due to their very short-term nature, subject to minimal interest rate risk. We currently do not hedge interest rate exposure. Because of the short-term maturities of our cash equivalents, we do not believe that an increase in market rates would have any material negative impact on the value of our investment portfolio. We have no investments denominated in foreign currencies and therefore our investments are not subject to foreign currency exchange risk.

Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act), defines the term “disclosure controls and procedures” as those controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on their evaluation as of June 30, 2016, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

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 quarter ended June 30, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We are not currently a party to any litigation and we are not aware of any pending or threatened litigation against us that could have a material adverse effect on our business, operating results or financial condition. The medical device industry in which we operate is characterized by frequent claims and litigation, including claims regarding patent and other intellectual property rights as well as improper hiring practices. As a result, we may be involved in various legal proceedings from time to time.

There have been no material changes during the three months ended June 30, 2016 to the risk factors set forth in Part I, Item 1A, Risk Factors, of our Annual Report on Form 10-K for the year ended December 31, 2015 and in Part II, Item 1A, Risk Factors, of our Quarterly Report on Form 10-Q for the Quarter ended March 31, 2016.

The list of exhibits on the accompanying Exhibit Index are filed or incorporated by reference (as stated therein) as part of this Quarterly Report on Form 10-Q.

Pursuant to the requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
