On December 16, 2014, the Company issued $125.0 million aggregate principal amount of the 2019 Notes. On December 22, 2014, the Company announced the closing of the initial purchasers’ exercise in full of their option to purchase an additional $18.75 million aggregate principal amount of the 2019 Notes. The 2019 Notes bore interest at a fixed rate of 3.75% per year, payable semiannually in arrears on June 15 and December 15 of each year, beginning on June 15, 2015 and matured on December 15, 2019, unless earlier repurchased, redeemed or converted. The 2019 Notes were convertible into shares of the Company’s common stock, cash or a combination thereof. On May 20, 2015, the Company received shareholder approval for the increase in the number of shares of common stock authorized and available for issuance upon possible conversion of the 2019 Notes.

On April 27, 2018, the Company entered into separate exchange agreements with certain holders of the 2019 Notes. The agreements gave the holders the right to exchange, in aggregate, $75.1 million of the 2019 Notes for $75.1 million of the 2023 Notes. The 2023 Notes bear a fixed interest rate of 4.75% per year, payable semi-annually with the principal payable in May 2023. At the option of the holders, the 2023 Notes are convertible into shares of the Company’s common stock, cash or a combination thereof. The initial conversion rate is $4.45 per share, subject to certain adjustments, related to either the Company's stock price volatility, or the Company's declaration of a stock dividend, stock distribution, share combination or share split expected dividends or other anti-dilutive activities. In addition, holders will be entitled to receive additional shares of common stock for a potential increase of the conversion rate up to $280.90 per share under a make-whole provision in some circumstances. The Company incurred debt issuance costs of $1.6 million upon issuance of the 2023 Notes.

In accordance with accounting for convertible debt within the cash conversion guidance of ASC 470-20, the Company allocated the principal amount of the 2023 Notes between its liability and equity components. The carrying amount of the liability component was determined by measuring the fair value of a similar debt instrument of similar credit quality and maturity that did not have the conversion feature. The carrying amount of the equity component, representing the embedded conversion option, was determined by deducting the fair value of the liability component from the principal amount of the 2023 Notes as a whole. The equity component was recorded to additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the 2023 Notes over the carrying amount of the liability component was recorded as a debt discount of $19.0 million, and is being amortized to interest expense using the effective interest method through the maturity date. The Company allocated the total amount of debt issuance costs incurred to the liability and equity components using the same proportions as the proceeds from the 2023 Notes. The debt issuance costs attributable to the liability component were recorded as a direct deduction from the liability component of the 2023 Notes and are being amortized to interest expense using the effective interest method through the maturity date. Transaction costs attributable to the equity component were netted with the equity component of the 2023 Notes in additional paid-in capital. The effective interest rate of the 2023 Notes, inclusive of the debt discount and issuance costs, is 11.9%.

The exchange of $75.1 million of the 2019 Notes for the 2023 Notes is considered a debt extinguishment under ASC 470-50. The 2019 Notes are accounted for under cash conversion guidance ASC 470-20, which requires the Company to allocate the fair value of the consideration transferred upon settlement to the extinguishment of the liability component and the reacquisition of the equity component upon derecognition. In accordance with the aforementioned guidance, the Company allocated a portion of the $75.1 million to the extinguishment of the liability component equal to the fair value of that component immediately before extinguishment and recognized a $2.5 million extinguishment loss in the Consolidated Statement of Operations to measure the difference between (i) the fair value of the liability component and (ii) the net carrying amount of the liability component (which is already net of any unamortized debt issuance costs). In addition, the Company recorded a $7.6 million reduction of Additional Paid in Capital in connection with the extinguishment of $75.1 million of the 2019 Notes.

In December 2018 the Company used $52.8 million of proceeds from the Senior Credit Facilities (see below) to repurchase a portion of the 2019 Notes as well as $0.3 million of proceeds to pay for transaction costs. The repurchase of the 2019 Notes is considered a debt extinguishment under ASC 470-50. The 2019 Notes are accounted for under cash conversion guidance ASC 470-20, which requires the Company to allocate the fair value of the consideration transferred upon settlement to the extinguishment of the liability component and the reacquisition of the equity component upon derecognition. In accordance with the guidance above, the Company allocated a portion of the $52.8 million to the extinguishment of the liability component equal to the fair value of that component immediately before extinguishment and recognized a $1.7 million extinguishment loss in the Consolidated Statement of Operations to measure the difference between (i) the fair value of the liability component and (ii) the net carrying value amount of the liability component (which is already net of any unamortized debt issuance costs). In

In the beginning of 2019, the Company used a total of $2.7 million of proceeds from the Senior Credit Facilities to repurchase a portion of the remaining 2019 Notes. The repurchase of the 2019 Notes is considered a debt extinguishment under ASC 470-50. The 2019 Notes are accounted for under cash conversion guidance ASC 470-20, which requires the Company to allocate the fair value of the consideration transferred upon settlement to the extinguishment of the liability component and the reacquisition of the equity component upon derecognition. In accordance with the guidance above, the Company allocated a portion of the $2.7 million to the extinguishment of the liability component equal to the fair value of that component immediately before extinguishment and recognized a $0.2 million extinguishment loss in the Consolidated Statement of Operations to measure the difference between (i) the fair value of the liability component and (ii) the net carrying value amount of the liability component (which is already net of any unamortized debt issuance costs). The reduction of Additional Paid in Capital in connection with this extinguishment was immaterial. The Company settled the remaining 2019 Notes of $13.0 million in principal upon its maturity in December 2019.

On October 31, 2019, the Company closed its offering of the 2023 Series B Notes in the aggregate principal amount of $34.4 million. The 2023 Series B Notes will mature in May 2023 and are convertible at the option of the holder at any time prior to maturity at an initial conversion price of $0.72 per share, subject to adjustment under certain circumstances. The 2023 Series B Notes and any shares of common stock issuable upon conversion of the 2023 Series B Notes (the “Conversion Shares”) have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state or other jurisdiction’s securities laws, and the 2023 Notes and the Conversion Shares may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state or other jurisdictions’ securities laws. The Company does not intend to file a registration statement for the resale of the 2023 Series B Notes or any Conversion Shares.

As part of the offering, the Company entered into agreements with certain holders of its existing 2023 Notes to exchange $9.0 million of the 2023 Notes for $5.1 million of the 2023 Series B Notes. The gross cash proceeds of approximately $29.3 million from the financing were used to extinguish the Company’s existing 2019 Notes in December 2019 and intended to pay amounts owing with respect to other indebtedness and to fund general corporate and working capital requirements. The 2023 Series B Notes bear interest at a rate of 7.00% per annum if paid in cash, semiannually in arrears on May 1 and November 1 of each year, beginning on May 1, 2020. The Company also has an option, and has agreed with its senior lender, to PIK the interest at 8.00% per annum, to defer cash payments. The net proceeds from the financing were $26.9 million after deducting a total of $2.3 million of the initial purchasers’ discounts and professional fees associated with the transaction.

Under ASC 470-60, Troubled Debt Restructurings by Debtors, the exchange of the $9.0 million of the 2023 Notes for the $5.1 million of the 2023 Series B Notes represents a troubled debt restructuring ("TDR"). The TDR did not result in a gain recognition. As a result, a new effective interest rate was established based on the $7.2 million carrying value of the original debt, net of the $2.0 million fair value of the embedded derivative liability related to the new debt issued in the TDR and $0.2 million issuance costs, getting accreted to $6.8 million representing the total amount of the future undiscounted cash flows related to the $5.1 million of the 2023 Series B Notes.

In accordance with ASC 815-15, Derivatives and hedging, Embedded Derivatives, the embedded conversion option should be bifurcated and separately accounted for as a derivative instrument, because the Company did not have enough authorized shares available to share-settle the conversion option. Such derivative instruments should be initially and subsequently measured at fair value, with changes in fair value recognized in earnings (see Note 7). The derivative liability recorded at the issuance date was $13.5 million, including the $2.0 million above accounted for in the TDR, which was subsequently remeasured to $6.8 million as of December 31, 2019, with $6.8 million recognized as a gain on change in fair value of derivative in the Company's statement of operations. Further, the $0.9 million of allocated issuance costs associated with the bifurcated conversion features embedded in the notes was recognized as a loss on debt restructuring in the Company’s statement of operations for the year ended December 31, 2019. In accordance with ASC 470-20, the initial carrying amount of the liability component of the 2023 Series B Notes, excluding the $5.1 million portion above is accounted for as a TDR, upon issuance is the residual amount between total proceeds from the transaction and the derivative liability net of allocated issuance costs. The $1.4 million debt issuance costs attributable to the liability component were recorded as a direct deduction from the liability component of the 2023 Series B Notes and are being amortized to interest expense using the effective interest method through the maturity date. The discount from the par amount of the 2023 Series B Notes will be accreted to par utilizing the effective-interest rate method over the term of the Notes from the issuance date through May 2023. The effective interest rate of the 2023 Notes, inclusive of the debt discount and issuance costs is 27.4%.

On June 1, 2018, the Company entered into a credit agreement for $25.0 million in original principal amount of term loans secured by all Company assets (the “Prior Term Loan”). The Prior Term Loan incurred debt issuance costs of $0.5 million and a debt discount of $0.4 million. The debt discount is due to lender fees paid on the initial drawdown of $15.0 million. The debt issuance costs and debt discount were amortized to interest expense using the effective interest method through the maturity date. In December 2018, the Company used $25.6 million of proceeds from the Senior Credit Facilities (see below) to repay the Prior Term Loan which was comprised of $25.0 million of principal, $0.5 million of transaction costs and $0.1 million of interest. The repayment of the Prior Term Loan is considered a debt extinguishment under ASC 470-50. In 2018, the Company recorded $1.3 million of extinguishment loss related to the repayment of the Prior Term Loan in the Consolidated Statement of Operations.

On December 13, 2018 we entered into the Senior Credit Facilities, consisting of the Revolver and Term Loans. The Senior Credit Facilities also included a $15.0 million delayed draw term loan b commitment, which remained undrawn and expired on October 31, 2019. As of December 31, 2019, $25.0 million was drawn under the Revolver and $88.5 million of Term Loans were outstanding. As of December 31, 2019, the Revolver was fully drawn. The Company extended commitments related to undrawn amounts of the Delayed Draw Term Loan A from June 30, 2019 to December 13, 2019, pursuant to an amendment the Company entered with the Second Lien Agent on July 18, 2019. The extended Delayed Draw Term Loan A was subsequently drawn down by the Company in December 2019. Drawn amounts under the Delayed Draw Term Loans mature at the same time as the Initial Term Loan. The Term Loans mature on the earliest to occur of the June 23, 2024 and the date of that is 181 days prior to the maturity date of each of (x) the 2023 Notes and (y) the 2023 Series B Notes. The Revolver matures on the earliest to occur of the June 23, 2024 and the date of that is 91 days prior to the maturity date of each of (x) the 2023 Notes and (y) the 2023 Series B Notes. The Company’s ability to borrow under the Revolver is subject to a borrowing base determined based upon eligible inventory, eligible equipment, eligible real estate and eligible receivables. The Senior Credit Facilities are secured by substantially all of the Company’s assets. All of the Company’s debt is subordinated to the Senior Credit Facilities. The liens securing the Term Loans are subordinate to the liens securing the Revolver. The Senior Credit Facilities had customary financial and non-financial covenants, including affirmative, negative and reporting covenants, representations and warranties, and events of default, including cross-defaults on other material indebtedness, as well as events of default triggered by a change of control and certain actions initiated by the FDA which were superseded by the amendments noted below. The financial covenants consisted of a minimum revenue test, a minimum adjusted EBITDA test and a maximum total net leverage ratio.

The Revolver bears interest at a fluctuating rate of interest equal to one, two, three or six-month LIBOR plus a margin of 3.75% or a rate based on the prime rate plus a margin of 2.75%. The Term Loans bear interest at a fluctuating rate of interest equal to one, two, three or six-month LIBOR plus a margin of 8.75% or a rate based on the prime rate plus a margin of 7.75%. Interest on the Senior Credit Facilities is payable in cash quarterly in arrears (or more frequently in connection with customary LIBOR interest provisions), provided, that the Company may elect (and has covenanted to the lenders under its First Lien Credit Agreement to) pay interest on the Term Loans in kind until the earlier to occur of the date upon which Company has provided financial statements demonstrating twelve-months of revenue of at least $125.0 million and (ii) December 28, 2020.

Amounts drawn under the Revolver may be prepaid at the option of the Company without premium or penalty, subject, in the case of acceleration of the Revolver or termination or reduction of the revolving credit commitments thereunder, to certain call protections which vary depending on the time at which such prepayments are made. Amounts drawn under the Revolver are subject to mandatory prepayment to the extent that aggregate extensions under the Revolver exceed the lesser of the revolving credit commitment then in effect and the borrowing base then in effect, and upon the occurrence of certain events and conditions, including non-ordinary course asset dispositions, receipt of certain insurance proceeds and condemnation awards and issuances of certain debt obligations. Amounts outstanding under the Term Loans may be prepaid at the option of the Company subject to applicable premiums, including a make-whole premium, and certain call protections which vary depending on the time at which such prepayments are made. Subject to payment of outstanding obligations under the Revolver as a result of any corresponding mandatory prepayment requirements thereunder, amounts outstanding under the Term Loans are subject to mandatory prepayment upon the occurrence of certain events and conditions, including non-ordinary course asset dispositions, receipt of certain insurance proceeds and condemnation awards, issuances of certain debt obligations and a change of control transaction.

In connection with the Revolver the Company incurred a debt discount of $0.5 million and debt issuance issue costs of $0.3 million. The debt discount is due to annual fees and lender fees paid on the initial drawdown of $15.0 million. The debt issuance costs and debt discount are recorded as an asset on the Consolidated Balance Sheet and are amortized to interest expense using the straight-line method through the estimated Revolver maturity date. The annual fees related to the Revolver

and the Initial Term Loan are amortized to interest expense using the straight-line method over the annual period they relate to. In connection with the Initial Term Loan and Delayed Draw Term Loan A, the Company incurred a debt discount of $1.8 million and debt issuance issue costs of $0.8 million. The debt discount is due to lender fees paid on the Initial Term Loan of $50.0 million and drawdown of Delayed Draw Term Loan A of $20.0 million. The debt issuance costs and debt discount costs are amortized to interest expense using the effective interest rate method through the estimated maturity date. In addition, the Company incurred $0.5 million of debt issuance costs related to the commitment fees paid to the lenders for the undrawn amounts of the Delayed Draw Term Loans. These debt issuance costs are recorded as an asset on the balance sheet and amortized on a straight-line basis over the access period of the Delayed Draw Term Loans through June 30, 2019. The effective interest rates, inclusive of the debt discounts and issuance costs, for the various borrowing tranches of the Revolver were between 6.2% and 9.1%. The effective interest rates, inclusive of the debt discounts and issuance costs for the Initial Term Loan and Delayed Draw Term Loan A were between 9.1% and 12.2%.

The Initial Term Loan of $50.0 million and $15.0 million of the Revolver were drawn by the Company on December 13, 2018. On December 21, 2018, the Company drew $20.0 million of the Delayed Draw Term Loan A. In January 2019, the Company drew $5.0 million and subsequently the remaining $5.0 million under the Revolver were drawn down by the Company in April 2019. On September 18, 2019, pursuant to terms of the First Lien Credit Agreement, the Company borrowed an advance in the aggregate principal amount of $2.5 million (the “Protective Advance”). The Protective Advance is a secured Obligations under the First Lien Credit Agreement, and bears interest at the rate applicable to the Revolver. The Protective Advance was subsequently repaid in November 2019 along with a repayment fee of $0.1 million. The Company drew down the remaining $10.0 million under its borrowing capacity of Delayed Draw Term Loan A before its expiry in December of 2019. The $15.0 million Delayed Draw Term Loan B expired upon the issuance of the 2023 Series B Notes, prior to the Company drawing down any monies.

The Term Loans are governed by the Second Lien Credit Agreement. The Term Loans include a 24-month paid-in-kind interest option available to the Company should it choose to defer cash payments in order to maintain the liquidity needed to continue launching new products, and preparing for an FDA prior approval inspection of its new injectable manufacturing facility. The Company has elected the paid-in-kind interest option and increased the principal balance of Term Loans by $8.5 million for the twelve month periods ended December 31, 2019 respectively.

On April 6, 2020, the Company entered into amendments pertaining to the Senior Credit Facilities. The amendments collectively among other things, (i) increase the interest rates on April 6, 2020, (ii) reset certain prepayment premiums and modify the terms of certain mandatory prepayments and (iii) modify certain financial covenant levels inclusive of the disposition of prior covenants as of and for the period ended December 31, 2019. Additional information pertaining to the Senior Credit Facilities amendments is included in the Subsequent Event footnote.
