The terms of the Original Loan Agreement provided for two term loans in aggregate of $10,000,000 comprised of a $4,000,000 term loan and a $6,000,000 term loan. In connection with the Merger, the Company assumed and became the borrower under TransEnterix Surgical’s Original Loan Agreement, and agreed to amendments to the Original Loan Agreement, dated as of September 3, 2013 and October 31, 2013, respectively. The Original Loan Agreement had a maturity date of January 1, 2016 and a fixed interest rate of 8.75% per annum. As of September 26, 2014, the outstanding principal amount of the Original Loan Agreement was $5,604,000. On September 26, 2014, the Company entered into the Amended and Restated Loan Agreement with the Lenders. Under the Amended and Restated Loan Agreement, the Lenders agreed to make certain term loans (the “Amended and Restated Term Loans”) in an aggregate principal amount of up to $25,000,000. The first tranche of the Amended and Restated Term Loans increased the Company’s borrowings at September 26, 2014 from $5,604,000 to $10,000,000. The Amended and Restated Term Loans allowed for interest-only payment at 7.5% per annum through October 31, 2015 and a maturity date of April 1, 2018. On August 14, 2015, the Company entered into the First Amendment to the Amended and Restated Loan Agreement (the “First Amendment”) with the Lenders. The first tranche of the First Amendment increased the Company’s borrowings at August 14, 2015 from $10,000,000 to $20,000,000. The First Amendment allowed for interest-only payments at 7.5% per annum through April 30, 2016 and a maturity date of October 1, 2018. On September 18, 2015, in connection with entry into the Purchase Agreement with SOFAR S.p.A. (see Note 3 for a description of the related transactions), the Company and the Lenders entered into the Consent and Second Amendment to Amended and Restated Loan Agreement (the “Second Amendment”). The Second Amendment modified the period in which the Company can make interest-only payments at 7.5% per annum on the term loans until January 31, 2016. The Second Amendment has a maturity date of July 1, 2018. In connection with the entry into the loan agreements, the Company became obligated to pay final payment and facility fees. The final payment fee obligation paid under the Original Loan Agreement at 3.33% was $333,000 and the facility fee payment was $75,000. The final payment fee obligation paid under the Amended and Restated Loan Agreement at 5.45% was $165,920 and the facility fee was $90,000. The facility fee paid under the First Amendment was $90,000. The final payment fee obligation payable under the Second Amendment is 6.5% of the original principal amount of each term loan without the interest only extension and 8.0% with both interest-only extensions. In addition, in connection with the borrowings, the Company issued warrants to the Lenders to purchase shares of the Company’s common stock amounting to 279,588 warrants under the Original Loan Agreement, 38,324 warrants under the Amended and Restated Loan Agreement and 112,903 under the First Amendment. Additional warrants will be issued if additional tranche term loans are made. The warrants expire seven years from their respective issue date. The Amended and Restated Loan Agreement, as amended, is secured by a security interest in all assets of the Company and its current and future U.S. subsidiaries, including a security interest in intellectual property proceeds, but excluding a current security interest in intellectual property. The Amended and Restated Loan Agreement contains customary representations (tested on a continual basis) and covenants that, subject to exceptions, restrict the Company’s ability to do the following things: declare dividends or redeem or repurchase equity interests; incur additional liens; make loans and investments; incur additional indebtedness; engage in mergers, acquisitions, and asset sales; transact with affiliates; undergo a change in control; add or change business locations; and engage in businesses that are not related to its existing business. 13. Notes Payable (Continued) Further, under the Second Amendment, the Lenders consented to the formation of TransEnterix International, the entry of the Company into the Purchase Agreement and other transaction documents, and the name change of TransEnterix Italia. The Company agreed to pledge 100% of the common stock of TransEnterix International as additional security for the borrowings under the Amended and Restated Loan Agreement, as amended. The Second Amendment added a provision permitting the Company to transfer designated amounts to TransEnterix Italia during the term of the Amended and Restated Loan Agreement. This provision for the transfer of designated amount was amended on November 13, 2015 with the Third Amendment to the Amended and Restated Loan Agreement. On April 19, 2016, the Company and its U.S. subsidiaries entered into the Consent and Fourth Amendment to the Loan Agreement (the “Fourth Amendment”) pursuant to which TransEnterix International, joined the Loan Agreement and the existing promissory notes as a co-borrower thereunder and pledged, as collateral for the obligations under the Loan Agreement, substantially all of its non-intellectual property assets, including up to 65% of the equity interests owned by TransEnterix International in TransEnterix Europe S.Á.R.L, a wholly owned subsidiary of TransEnterix International. On September 7, 2016, the Company and its U.S. subsidiaries entered into the Fifth Amendment to the Loan Agreement (the “Fifth Amendment”). The Fifth Amendment provides more flexibility to the Company with respect to its intercompany activities with its foreign subsidiaries and adds an affirmative covenant requiring the Company to maintain a $10.0 million cash balance in accounts held with the Lender. Cash amounts related to this requirement are included in restricted cash on the consolidated balance sheet. In accordance with ASC 470-50 Debt – Modifications and Extinguishments, it was determined that the debt refinancing on September 26, 2014, was considered to be a debt modification. Accordingly, the Company recorded approximately $129,000 of debt discount, consisting of the $75,000 facility fee and the relative fair value of warrants on the issue date of $54,000. Additionally, approximately $30,000 of legal fees were recorded as a result of the transaction. The debt discount and deferred financing costs will be amortized over the life of the new debt agreement using the effective interest method into interest expense, net. In accordance with ASC 470-50 Debt – Modifications and Extinguishments, it was determined that the debt refinancings on August 14, 2015, September 18, 2015, April 19, 2016 and September 7, 2016 were considered to be debt modifications. Additionally, during the third quarter of 2015, the Company adopted ASU No. 2015-03, “Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs”. ASU 2015-03 requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. The Company recorded a debt discount of approximately $210,000 for these two amendments. Accordingly, the unamortized debt discount is presented as a reduction of the related debt liability in the Company’s balance sheet. In accordance with ASU 2015-03, this adopted guidance was applied retrospectively. The debt discount will be amortized over the life of the new debt agreement using the effective interest method into interest expense, net. In connection with the issuance of the notes payable and its amendments, TransEnterix Surgical incurred approximately $371,000 in debt issuance costs paid to lenders and third parties and $280,000 in debt issuance costs related to issuance of warrants to the lenders. The unamortized balance of $143,000 as of September 30, 2016 will be amortized using the effective interest method.
