On December 1, 2020, the Company refinanced a $15.0 million term loan with Horizon Technology Finance Corporation through the issuance of a senior secured note with an aggregate principal amount of $43.0 million issued on December 1, 2020 (the “December

2020 Note”) to High Trail Investments SA LLC (“High Trail SA”). The Company received gross proceeds of $38.0 million in exchange for the December 2020 Note. The December 2020 Note was to be repaid over 24 equal monthly cash payments of $1.8 million. The December 2020 Note was extinguished on April 8, 2021 in exchange for an April 2021 Note (see the discussion under the heading High Trail April 2021 of this Note 6 below).

On February 2, 2021, the Company entered into a second, separate transaction with High Trail Investments ON LLC (“High Trail ON” and, together with High Trail SA, “High Trail”), where it issued to High Trail ON a 0% coupon senior secured promissory note in an aggregate principal amount of $16.5 million (as amended, the “February 2021 Note”) that was to mature on February 1, 2023.

On April 8, 2021, the Company refinanced all its existing debt with High Trail and Midcap Funding IV Trust (“MidCap”). As such, the Company entered into a new securities purchase and exchange agreement (the “Securities Purchase Agreement”) with High Trail SA and High Trail ON, pursuant to which, among other things, the Company issued and sold to High Trail, in a private placement transaction (the “2021 Private Placement”), (i) senior secured promissory notes in an aggregate principal amount of $110.0 million (the “April 2021 Notes”) that accrued interest at a rate of 8% per annum and were to mature on April 8, 2024, and (ii) warrants to purchase up to an aggregate of 2,259,166 shares of the Company’s common stock in exchange for: (a) a cash payment by High Trail to the Company of $57.7 million, (b) the cancellation of the December 2020 Note, and (c) the cancellation of the February 2021 Note. On April 8, 2021, the Company used $14.8 million of the net proceeds from the 2021 Private Placement to repay all amounts owed under the 2018 $25.0 million credit facility with MidCap (the “2018 Credit Facility”). Pursuant to ASC Topic 470, Debt, the Company concluded the High Trail April 2021 Note transaction resulted in the extinguishment of the two prior High Trail December 2020 and February 2021 term loans in the amount of $28.2 million of extinguishment of which has been classified within loss on extinguishment of debt on the condensed consolidated statements of operations. The Company breached its Adjusted EBITDA covenant with its lender, High Trail, and in August 2021, the Company secured a waiver from its lender with the partial repayment of the loan. See the High Trail Letter Agreements and Omnibus Amendment section for additional information.

On April 8, 2021, the Company entered into a Letter Agreement (the “April Letter Agreement”) with High Trail SA and High Trail ON, pursuant to which, among other things, (i) the Company and High Trail SA agreed to amend the terms of the Letter Agreement to provide that the Company would prepare and file by June 30, 2021 a registration statement (the “Resale Registration Statement”) with the Securities and Exchange Commission for the purposes of registering for resale the December Warrant Shares, the Penny Warrant Shares and the Restricted Shares (as defined below), (ii) the Company issued 130,000 shares of its common stock to High Trail SA (the “Restricted Shares”), and (iii) High Trail SA and High Trail ON agreed to waive any Default or Event of Default (as such terms are defined in the December 2020 Note or the February 2021 Note) caused by the Company’s failure to file a resale registration statement by March 26, 2021. On April 8, 2021, the Company entered into (i) an amendment (the “SPA Amendment”) to that certain Securities Purchase Agreement, dated as of November 30, 2020, by and between the Company and High Trail SA (the “December 2020 SPA”), and to that certain Securities Purchase Agreement, dated as of February 2, 2021, by and between the Company and High Trail ON (the “February 2021 SPA”), (ii) an amendment to the February Warrant (the “February Warrant Amendment”), (iii) an amendment to the Penny Warrant (the “Penny Warrant Amendment”), and (iv) an amendment to the Additional Warrant (the “Additional Warrant Amendment” and, together with the February Warrant Amendment and the Penny Warrant Amendment, the “Warrant Amendments”). The SPA Amendment amended the December 2020 SPA and the February 2021 SPA to, among other things, allow for the issuance of the April 2021 Notes and to waive certain rights of High Trail under the December 2020 SPA and the February 2021 SPA. The Warrant Amendments amended the February Warrant, the Penny Warrant and the Additional Warrant to amend the definition of “Black Scholes Value” in each warrant to provide that the expected volatility used in the Black Scholes Value shall equal 100% instead of the greater of 100% and the 100-day volatility obtained from the HVT function on Bloomberg (determined utilizing a 365-day annualization factor) as of the trading day immediately following the public announcement of a Change of Control (as defined in each of the warrants), or, if the Change of Control is not publicly announced, the date the Change of Control is consummated. The Warrant Amendments to the February Warrant, the Penny Warrant and the Additional Warrant resulted in an $80.0 million reclassification from a liability to a component of equity and resulted in a $21.3 million reclassification from a component of equity to a liability as of December 31, 2021. The Restricted Shares were expensed as part of extinguishment loss, valued based on the fair market value on April 8, 2021 for $4.1 million, with the offset impacting stockholders’ equity.

On August 9, 2021, pursuant to those certain Letter Agreements entered into between the Company and High Trail with respect to each of the April 2021 Notes (collectively, the “August Letter Agreements”), High Trail notified the Company that High Trail

declared an event of default under the April 2021 Notes as a result of the Company’s Adjusted EBITDA (as defined in the April 2021 Notes) not being equal to at least $12 million for the 12 month period ended June 30, 2021 and further notified the Company that High Trail immediately accelerated a total of $18.7 million of the principal amount of the April 2021 Notes, requiring the Company to immediately pay $21.5 million (such amount equal to 115% of the principal amount that was accelerated, as required under the terms of the April 2021 Notes, plus $0.3 million of accrued but unpaid interest on the principal amount that was accelerated) (the “Current Event of Default Acceleration Amount”). Pursuant to the August Letter Agreements, the Company agreed, among other things, to pay the Current Event of Default Acceleration Amount in cash by August 9, 2021 and that any portion not paid in cash would be paid in shares of the Company’s common stock under the terms of the April 2021 Notes, with the number of shares issuable equal to the unpaid Current Event of Default Acceleration Amount divided by 80% of the lesser of (i) the Daily VWAP (as defined in the April 2021 Notes) on August 9, 2021 and (ii) the average of the lowest two (2) Daily VWAPs during the ten (10) day VWAP trading period ending on August 9, 2021. Pursuant to the August Letter Agreements, High Trail waived the events of default relating to the Company’s failure to satisfy the Adjusted EBITDA covenant under the April 2021 Notes, effective upon the payment in cash of $10.1 million of the Current Event of Default Acceleration Amount and the issuance of the shares of the Company’s common stock for the remaining $11.7 million of the Current Event of Default Acceleration Amount. The Company paid High Trail an aggregate of $10.1 million in cash on August 9, 2021 and in accordance with the April 2021 Notes and the August Letter Agreements, paid the remaining $11.7 million of the Current Event of Default Acceleration Amount by issuing to High Trail an aggregate of 2,841,251 shares of common stock (with the shares issued at a price of $4.1007 per share, which was, in accordance with the April 2021 Notes, equal to 80% of the Daily VWAP on August 9, 2021). In connection with the August Letter Agreements, on August 9, 2021, the Company also entered into an Omnibus Amendment to Senior Secured Notes Due 2024 and Warrants to Purchase Common Stock with High Trail (the “Omnibus Amendment”), whereby: (i) the Company agreed to increase the minimum cash threshold covenant in the April 2021 Notes from $15.0 million to $30.0 million through October 31, 2021; (ii) the Company agreed to add a liquidity covenant to the April 2021 Notes whereby it must have liquidity, on each day through October 31, 2021, calculated as (A) inventory, net, plus (B) accounts receivable, net (each determined in accordance with GAAP) in an aggregate minimum amount equal to $65.0 million less (C) any amount of cash and cash equivalents in excess of $30 million; (iii) the definition of “Permitted Investment” in the April 2021 Notes was modified such that the consent of High Trail was now required for certain merger and acquisition activity; (iv) the Company agreed that the exercise prices of the following warrants to purchase shares of the Company’s common stock previously issued to High Trail will be modified to be equal to the lesser of: (X) the closing price of the Company’s common stock on August 9, 2021 or (Y) the VWAP of the Company’s common stock on August 9, 2021: (1) the February Warrant; (2) the Additional Warrant; and (3) the Warrants (collectively, the “High Trail Warrants”); (v) High Trail agreed that it would not exercise the High Trail Warrants prior to October 17, 2021 (the day that was 60 days after the registration statement registering for resale the 2,666,667 shares of common stock the Company issued on June15, 2021 was declared effective); and (vi) if, at any time on or after January 7, 2022, High Trail is unable to exercise the High Trail Warrants due to the agreement described in clause (v), the Company agreed to pay High Trail, as liquidated damages, a cash payment that will be equal to (a) the weighted average price of the Company’s common stock on the date High Trail seeks to exercise any of the High Trail Warrants, minus the then-current exercise price of the High Trail Warrants, multiplied by (b) the number of shares subject to the High Trail Warrants that it then desires to exercise.

On September 22, 2021, the Company entered into letter agreements (the “September Letter Agreements”) with High Trail with respect to the April 2021 Notes. Pursuant to the September Letter Agreements, (i) High Trail notified the Company that High Trail declared events of default under the April 2021 Notes and further notified the Company that High Trail accelerated an aggregate of $66.3 million of the principal amount of the April 2021 Notes, requiring the Company to pay $76.9 million (such amount equal to 115% of the principal amount that was accelerated, as required under the terms of the April 2021 Notes, plus $0.3 million of accrued but unpaid interest on the principal amount that was accelerated) (collectively, the “Acceleration Amount”), (ii) High Trail agreed, contingent and effective upon the repayment of the Acceleration Amount in shares of the Company’s common stock in accordance with the April 2021 Notes and the September Letter Agreements and the satisfaction of all of the Company’s other obligations under the September Letter Agreements and the Second Omnibus Amendment (as defined below), to waive the events of default, (iii) the Company agreed that until November 1, 2021, the Company would not, subject to certain exceptions, issue, offer, sell or otherwise dispose of any equity security, equity-linked security or related security, and (iv) the Company agreed that, as a result of the occurrence of the events of default, it no longer has the right to require High Trail to exercise the High Trail Warrants if the price of the Company’s common stock exceeds 200% of the exercise price of the High Trail Warrants for 20 consecutive trading days and certain other conditions were satisfied. Under the terms of the April 2021 Notes, High Trail had the right, by delivering a notice to the Company (each, a “Stock Payment Notice”) to require the Company to satisfy its obligation to repay all or any portion of the Acceleration Amount in shares of the Company’s common stock, with the number of shares issuable determined by dividing the portion of the Acceleration Amount that High Trail requests, pursuant to a Stock Payment Notice, to be repaid in shares of the Company’s common stock, by 80% of the lesser of (A) the Daily VWAP (as defined in the April 2021 Notes) on the date of delivery of the Stock Payment Notice, and (B) the average of the lowest two Daily VWAPs during the ten (10) day VWAP trading period ending on the date of delivery of the Stock Payment Notice. Pursuant to the September Letter Agreements, High Trail agreed to deliver Stock Payment Notices as soon as it was practicable to do so without High Trail and its affiliates collectively beneficially owning in the aggregate in excess of 9.99% of the Company’s outstanding common stock. In connection with the September Letter

Agreements, on September 22, 2021, the Company also entered into a Second Omnibus Amendment to Senior Secured Notes Due 2024 and Warrants to Purchase Common Stock with High Trail (the “Second Omnibus Amendment”), whereby: (i) the maturity date of the April 2021 Notes was changed from April 8, 2024 to April 1, 2023; (ii) the definition of “Permitted Investment” in the April 2021 Notes was modified to include an exception for certain acquisitions of all or substantially all of the assets of another person or a majority of the equity interests of another person; (iii) the definition of “Target Adjusted EBITDA” was modified to reflect certain updated projections of the Company; (iv) the liquidity requirements as set forth in the Omnibus Amendment were removed; (v) the minimum cash threshold covenant was changed from $30.0 million to $15.0 million; (vi) the definition of “Adjusted EBITDA” in the April 2021 Notes was modified to be equal to not less than the Target Adjusted EBITDA for the three-month period ending on the last day of each applicable fiscal quarter instead of the 12-month period ending on such day; and (vii) the exercise prices of the High Trail Warrants were modified to be equal to $0.01. High Trail reserved the right to void the term of the Second Omnibus Amendment in full or in part in the event that the Company breached any of the terms of the September Letter Agreements or otherwise failed to timely deliver shares of stock of the Company to High Trail as required thereunder. In accordance with the April 2021 Notes and the September Letter Agreements, effective September 22, 2021, the Company issued to High Trail an aggregate of 3,474,814 shares of its common stock, and effective September 23, 2021, the Company issued to High Trail an aggregate of 5,838,096 shares of its common stock, satisfying its obligation to repay the Acceleration Amount in full. Pursuant to ASC Topic 470, Debt, the Company concluded that as a result of the High Trail Letter Agreements and Omnibus Amendment and the High Trail Debt Repayment, the April 2021 Notes were extinguished on September 22, 2021 in exchange for the $25.0 million of Notes due April 2023. The Company paid off the remaining $25.0 million High Trail Term Loan as of December 31, 2021 (see the discussion under the heading MidCap Credit Facility - December 2021 of this Note 6 below). Pursuant to ASC Topic 470, Debt, the Company concluded the High Trail Term Loan transaction resulted in the extinguishment of the High Trail Term Loan in the amount of $2.5 million of extinguishment, which has been classified within loss on extinguishment of debt on the consolidated statements of operations. For the year-ended December 31, 2021, the Company recorded a total of $138.9 million of debt extinguishment loss which includes the $107.0 million from the High Trail Letter Agreements and Omnibus Amendment and the High Trail Debt Repayment, $28.2 million from the High Trail December 2020 and February 2021 term loans as part of the issuance of the April 2021 Notes, of $2.5 million of extinguishment from the remaining $25.0 million of High Trail Term Loan and $1.5 million from the repayment of the 2018 Credit Facility.

On December 22, 2021, the Company entered into a Credit and Security Agreement (the “Credit Agreement”) together with certain of its subsidiaries party thereto as borrowers, the entities party thereto as lenders (the “Lenders”), and MidCap, as administrative agent, pursuant to which, among other things, (i) the Lenders agreed to provide a three year revolving credit facility in a principal amount of up to $50.0 million subject to a borrowing base consisting of, among other things, inventory and sales receivables (subject to certain reserves), and (ii) the Company agreed to issue to MidCap Funding XXVII Trust a warrant (the “MidCap Warrant”) to purchase up to an aggregate of 200,000 shares of common stock of the Company, par value $0.0001 per share, in exchange for the Lenders extending loans and other extensions of credit to the Company under the Credit Agreement. On December 22, 2021, the Company used $27.6 million of the net proceeds from the initial loan under the Credit Agreement to repay all remaining amounts owed under those certain senior secured promissory notes issued by the Company to High Trail Investments SA LLC and High Trail Investments ON LLC in an initial principal amount of $110.0 million, as amended (the “Terminated Notes”). The obligations under the Credit Agreement are a senior secured obligation of the Company and rank senior to all indebtedness of the Company. Borrowings under the Credit Agreement bear interest at a rate per annum equal to 5.50%, plus, at the Company’s option, either a base rate or a LIBOR rate. The Company will also be required to pay a commitment fee of 0.50% in respect of the undrawn portion of the commitments, which is generally based on average daily usage of the facility during the immediately preceding fiscal quarter. The Credit Agreement does not require any amortization payments. The Credit Agreement imposes certain customary affirmative and negative covenants upon the Company including restrictions related to dividends and other foreign subsidiaries limitations. The Credit Agreement minimum liquidity covenant requires that Midcap shall not permit the credit party liquidity at any time to be less than (a) during the period commencing on February 1st through and including May 31st of each calendar year, $12.5 million and (b) at all other times, $15.0 million of cash on hand. The Credit Agreement includes events of default that are customary for these types of credit facilities, including the occurrence of a change of control. The Company was in compliance with the financial covenants contained within the Credit Agreement as of September 30, 2022. The Company had approximately $0.0 million and $4.0 million of availability on the Midcap Credit Facility as of December 31, 2021 and September 30, 2022, respectively. The MidCap Warrant has an exercise price of $4.70 per share, subject to adjustment for stock splits, reverse stock splits, stock dividends and similar transactions, was immediately exercisable, has a term of ten years from the date of issuance and is exercisable on a cash or cashless basis. The Company evaluated the terms of each warrant to determine the appropriate accounting and classification pursuant to ASC 480 and ASC 815. Based on the Company’s evaluation, it concluded that the MidCap Warrant should be classified as equity with no subsequent remeasurement at each quarter so long as such warrants remain to be classified as equity.

On March 1, 2022, the Company entered into Securities Purchase Agreements (the “Purchase Agreements”) with certain accredited investors identified on the signature pages to the Purchase Agreements (collectively, the “Purchasers”) pursuant to which, among other things, the Company issued and sold to the Purchasers, in a private placement transaction (the “2022 Private Placement”), (i) 6,436,322 shares of the Company’s common stock (the “Shares”), and accompanying warrants to purchase an aggregate of 4,827,242 shares of common stock, and (ii) prefunded warrants to purchase up to an aggregate of 3,013,850 shares of common stock (the “Prefunded Warrants”) and accompanying warrants to purchase an aggregate of 2,260,388 shares of common stock. The accompanying warrants to purchase common stock are referred to herein collectively as the “Common Stock Warrants”, and the Common Stock Warrants and the Prefunded Warrants are referred to herein collectively as the “Warrants”. Under the Purchase Agreements, each Share and accompanying Common Stock Warrant were sold together at a combined price of $2.91, and each Prefunded Warrant and accompanying Common Stock Warrant were sold together at a combined price of $2.9099, for gross proceeds of approximately $27.5 million. In connection with the 2022 Private Placement, the Company entered into a registration rights agreement (the “Registration Rights Agreement”) with the Purchasers, pursuant to which the Company agreed to register for resale the Shares, as well as the shares of common stock issuable upon exercise of the Warrants (the “Warrant Shares”). Under the Registration Rights Agreement, the Company agreed to file a registration statement covering the resale by the Purchasers of the Shares and Warrant Shares within 30 days following the agreement date. The Company filed such resale registration statement on March 28, 2022, and it was declared effective by the SEC on April 8, 2022.

Upon the issuance of the Prefunded Warrants and stock purchase warrants, the Company evaluated the terms of each Warrant to determine the appropriate accounting and classification pursuant to ASC 480 and ASC 815. Based on the Company’s evaluation and due to certain terms in the warrant agreements, it concluded the Prefunded Warrant and the stock purchase warrants should be classified as liabilities with subsequent remeasurement at each quarter so long as such warrants remain to be classified as liabilities. The Company recorded an initial liability on issuance of $19.0 million from this conclusion. As of September 30, 2022, the Company has $6.3 million as the liability related to the Warrants.

On September 29, 2022, the Company entered into securities purchase agreements (the “September Purchase Agreements”) with certain accredited investors, pursuant to which, among other things, the Company agreed to sell and issue, in a registered direct offering (the “Registered Direct Offering”), an aggregate of 10,643,034 shares of its Shares and accompanying warrants to purchase an aggregate of 10,643,034 shares of its common stock. 10,526,368 of the Shares and the accompanying warrants to purchase 10,526,368 shares of common stock were sold to certain accredited Purchasers that are not affiliated with the Company at a combined offering price of $1.90 per share and accompanying warrant to purchase one share of common stock. The remaining 116,666 of the Shares and the accompanying warrants to purchase 116,666 shares of common stock were sold to certain insiders of the Company, comprised of the Company’s President and Chief Executive Officer, Chief Financial Officer, Chief Legal Officer and Global Head of M&A and Chief Technology Officer, at a combined offering price of $2.10 per share and accompanying warrant to purchase one share of common stock.

The Registered Direct Offering closed on October 4, 2022 and the Company issued and sold an aggregate of 10,643,034 shares of common stock to the Purchasers. The gross proceeds to the Company from the Registered Direct Offering were approximately $20.2 million, before deducting fees payable to the placement agent and other estimated offering expenses payable by the Company. The Company currently intends to use the net proceeds from the Registered Direct Offering for working capital purposes, the conduct of its business and other general corporate purposes, which may include acquisitions, investments in or licenses of complementary products, technologies or businesses.

Pursuant to the ASC 815-40, the September Purchase Agreement represents a legally binding contract that meets the definition of a firm commitment and as such the Company recorded a derivative related to the offering of common stock (“forward contract”) and associated warrants for the three months ended September 30, 2022. The Company also concluded both the forward contract and the warrants should be classified within stockholders’ equity within the condensed consolidated balance sheet as of September 30, 2022. Additionally, the Company recorded $12.8 million derivative expense derived from the excess of the fair-value of the issuances of equity of common shares and common stock warrants over the anticipated proceeds to be received by the Company. This expense was recorded in loss on initial issuance of equity on the condensed consolidated statement of operations for the nine months ended September 30, 2022.
