Convertible Notes

On December 16, 2014, the Company issued $125.0 million aggregate principal amount of Convertible 3.75% Senior Notes, due 2019, (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 bear 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 mature on December 15, 2019, unless earlier repurchased, redeemed or converted. The 2019 Notes are 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 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 new

Convertible 4.75% Senior Notes due 2023 (the “2023 Notes”). The new 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 $224.71 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 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 addition, the Company recorded a $2.9 million reduction of Additional Paid in Capital in connection with the extinguishment of the 2019 Notes. In January and February of 2019, the Company used $0.5 million and $2.2 million, respectively, of proceeds from the Senior Credit Facilities to repurchase the 2019 Notes.

2021 Term Loan

On June 1, 2018, the Company entered into a credit agreement for $25.0 million secured by all Company assets, due June 1, 2021 (“2021 Term Loan”). The 2021 Term Loan has limited financial and non-financial covenants inclusive of a minimum cash carry balance of $5.0 million. The 2019 Notes and 2023 Notes are subordinate to the 2021 Term Loan. The first $15.0 million million of loan proceeds was received on June 1, 2018. The remaining loan proceeds of $10.0 million were subject to closing conditions as defined in the agreement and were received on July 16, 2018. The 2021 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 are amortized to interest expense using the effective interest method through the maturity date. The 2021 Term Loan bears interest at a rate of LIBOR plus 9.0%, with a stated floor of 2.0%. The effective interest, inclusive of the debt discounts and issue costs, was 12.78% as of September 30, 2018. In December 2018, the Company used $25.6 million of proceeds from the Senior Credit Facilities (see below) to repay the 2021 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 2021 Term Loan is considered a debt extinguishment under ASC 470-50. The Company recorded $1.3 million of an extinguishment loss related to the repayment of the 2021 Term Loan in the Consolidated Statement of Operations.

Senior Credit Facilities

On December 13, 2018, the Company entered into a $25.0 million Revolving Credit Agreement (the “Revolver”) and Term Loan Agreement (the “2023 Term Loan”, and together with the Revolver, the “Senior Credit Facilities”). The Term Loan consists of (i) a $50.0 million initial term loan (the “Initial Term Loan”); (ii) a $30.0 million delayed draw term loan A (the “Delayed Draw Term Loan A”) and (iii) a $15.0 million delayed draw term loan B (the “Delayed Draw Term Loan B” and, together with the Delayed Draw Term Loan A, the “Delayed Draw Term Loans”). The Initial Term Loan matures on the earlier to occur of (a) three months prior to maturity of the 2023 Notes and (b) June 13, 2024. Commitments related to undrawn amounts of the Delayed Draw Term Loan A terminate on June 30, 2019, and drawn amounts under the Delayed Draw Term Loans mature at the same time as the Initial Term Loan. The Revolver matures on the earlier to occur of (a) six months prior to the maturity of the 2023 Notes and (b) December 13, 2023. 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 2023 Term Loan is subordinate to the Revolver. The Senior Credit Facilities have 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. The financial covenants consist of a minimum revenue test, a minimum adjusted EBITDA test and a maximum total net leverage ratio.

The interest rate under the Revolver and the 2023 Term Loan is calculated, at the option of the Company, at either the one, two, three or six-month London Inter-Bank Offered Rate (or LIBOR) plus 3.75% or the base rate plus 2.75%. The interest rate on the 2023 Term Loan is calculated, at the option of the Company, at either LIBOR plus 8.75% or the base rate plus 7.75%. Interest on the Senior Credit Facilities is payable in cash except that interest on the 2023 Term Loan is payable, at the option of the Company, in cash or in kind by being added to the principal balance thereof, until the earlier of December 13, 2020 and the date the Company has provided the lenders of the Senior Credit Facilities financial statements demonstrating that the Company has attained twelve months of revenue of at least $125.0 million. A commitment fee of 1.0% per annum is payable by the Company quarterly in arrears on the unused portion of the Delayed Draw Term Loans.

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 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 2023 Term Loan 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 2023 Term Loan 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.

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. As of December 31, 2018, the $10.0 million of the Delayed Draw Term Loan A, $15.0 million of the Delayed Draw Term Loan B and $10.0 million of the Revolver remain available to the Company. In addition, in January 2019, the Company drew $5.0 million from the remaining $10.0 million Revolver.

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. As of December 31, 2018, the effective interest, inclusive of the debt discounts and issue costs, of the Revolver and Initial Term Loan and Delayed Draw Term Loan A is 9.3% and 12.4%, respectively.
