was driven by the EIB warrant arrangement in the event that EIB elects full redemption. For more information on this transaction, see Note 6 to our unaudited condensed consolidated financial statements as of June 30, 2021, and for the six-month periods ended June 30, 2021, and 2020 set forth in Exhibit 99.1 hereto and incorporated herein by reference.
Since our inception, we have been in an operating cash flow deficit as we have made significant investments in our technology infrastructure, built out our research and development foundation, grown sales and marketing resources to drive revenue, and scaled general and administrative functions to enable operating effectiveness.
During the six months ended June 30, 2021, we issued additional convertible notes with a cumulative principal amount of $20.0 million, which mature in January and February 2025, respectively. Additionally, we received $1.7 million of forgiveness on our loan from the Small Business Administration Paycheck Protection Program. In April 2021 we entered into the FP Credit Agreement (as defined and further described below), utilizing a portion of those funds to pay-off our existing credit arrangements with EIB and Eastward. For additional detail regarding the terms associated with our financing arrangements, see Notes 6 and 7 to our unaudited condensed consolidated financial statements as of June 30, 2021 and for the six-month periods ended June 30, 2021 and 2020 set forth in Exhibit 99.1 hereto and incorporated herein by reference.
We expect that our principal sources of liquidity in 2021 will be the proceeds received from the Business Combination, the additional convertible notes issued and the FP Term Loan. We believe this will be sufficient to meet our working capital and capital expenditure needs over at least the next 12 months. Our future capital requirements will depend on many factors including our growth rate, the timing and extent of spending to support solution development efforts, the expansion of sales and marketing activities, the ongoing investments in technology infrastructure, the introduction of new and enhanced solutions, and the continuing market acceptance of our solutions. From time to time, we may seek additional equity or debt financing to fund capital expenditures, strategic initiatives or investments and our ongoing operations. In the event that we decide, or are required, to seek additional financing from outside sources, we may not be able to raise it on terms acceptable to us or at all. If we are unable to raise additional capital when desired, our business, financial condition and results of operations could be adversely affected.
FP Credit Agreement
On April 15, 2021, we entered into a credit agreement with FP Credit Partners, L.P., as agent for several lenders (the “FP Lenders”) which was then amended on May 17, 2021, for a $70.0 million term loan (the “FP Term Loan”). Upon funding in May 2021, the FP Term Loan was used to pay off the European Investment Bank (“EIB”) Loan Facility and the Eastward Loan Facility and to fund working capital and for general corporate purposes. We incurred $12.3 million of debt issuance costs relating to the FP Term Loan. Prior to the closing of the merger with NavSight, the FP Term Loan bore interest at a rate of 8.50% per annum, payable quarterly in arrears and we had the option to elect, upon written notice at least five business days in advance of each quarter end, to add all or a portion of the accrued unpaid interest to the outstanding principal amount of the FP Term Loan. Upon the closing of the merger with NavSight, this election was no longer available.
The FP Lenders had the option to elect to convert a portion of their specified contractual return into Old Spire common stock immediately preceding the closing of the merger with NavSight, at a conversion price specified in the credit agreement, by submitting a notice to convert on or prior to the funding date in May 2021, (the “Conversion Election”). If the FP Lenders had exercised the Conversion Election, and we did not elect to repay the outstanding principal amount of the FP Term Loan at the closing of the merger with NavSight, then the interest rate would have increased to 9% per annum. However, the FP Lenders did not make the Conversion Election and so the interest rate would have decreased to 4% per annum upon the closing of the merger with NavSight under the original terms of the FP Term Loan agreement. At the date of the FP Term Loan agreement, this contingent interest feature was determined to be an embedded derivative asset with an associated debt premium recorded. The fair value of this financial instrument is presented net within Long-term Debt on the Condensed Consolidated Balance Sheet at June 30, 2021.
The FP Term Loan, plus the applicable contractual returns as defined in the credit agreement, as amended, matures on April 15, 2026, and is collateralized by substantially all assets of Spire. We have the option to prepay the loan in advance of its final maturity, which was subject to a prepayment penalty under the original terms of the FP Term Loan agreement that varied between $17.5 million and $49.0 million based on the timing and circumstances of the repayment.
The FP Term Loan includes covenants that limit the Company’s ability to, among other things, make investments, dispose of assets, consummate mergers and acquisitions, incur additional indebtedness, grant liens, enter into transactions with affiliates, pay dividends or other distributions without preapproval by FP Credit Partners. We are required to maintain minimum unrestricted cash of at least $15.0 million as of each fiscal quarter end, except for the quarter immediately following the first quarter where the Company reports positive EBITDA, until the closing of a qualifying IPO. The Company issued an equity grant of 573,176 shares of its common stock with a value of $8.1 million to the FP Lenders upon funding of the FP Term Loan.
During the six months ended June 30, 2021, we recognized within Other expense, net on the Condensed Consolidated Statement of Operations, $5.0 million as a loss on extinguishment of debt resulting from paying off the EIB Loan and the Eastward Loan Facilities, and $1.7 million as a gain from extinguishment of debt resulting from the U.S. government’s forgiveness of the PPP loan.
In July 2021, we did not provide timely notice of our election to add the accrued unpaid interest as of June 30, 2021, to the outstanding principal and were therefore not in compliance with our payment obligations under the FP Term Loan. In August 2021, the FP Term Loan was amended to reinstate the Conversion Election and serve as formal notice of this election by the FP Lenders, and to waive this instance of our noncompliance with the written notification requirements. As a result, the FP Lenders received 873,942 shares of Old Spire common stock immediately prior to the closing of the merger with NavSight. In connection with FP’s exercise of the Conversion Election, the interest rate on the FP Term Loan increased to 9% per annum following the closing of the merger with NavSight. As a result of this interest rate increase under the FP Amendment, the contingent interest embedded derivative asset and associated debt premium were derecognized upon the execution of the FP Amendment. We have determined that this FP Amendment represents an accounting modification of the original FP Term Loan. In connection with the debt modification accounting, no gain or loss will be recorded related to the Amendment and we will capitalize the fair value of the 873,942 shares of Old Spire common stock issued to the FP Lenders to be amortized over the remaining life of the FP Term Loan as part of the effective yield of the FP Term Loan beginning in the third quarter of 2021.
