Orbis Education is an education services company that supports healthcare education programs for 17 universities across the United States. The closing of the Merger occurred on January 22, 2019 and, as a result of the Merger, GCE acquired all of the outstanding equity interests of Orbis Education for $365,834 in cash. The Company financed a portion of the purchase price through a consortium of banks led by our existing bank group, as described below. Senior Credit Facilities. Concurrently with the closing of the Merger, GCE entered into an amended and restated credit agreement, dated January 22, 2019, among GCE, Orbis Education, as guarantor, Bank of America, N.A. as administrative agent, swing line lender and letter of credit issuer, and the other lenders named therein (the “Credit Agreement”). The Credit Agreement provides for a $62,500 five-year senior secured revolving credit facility and a $187,500 five-year senior secured term loan facility (the “Senior Credit Facilities”). Concurrent with the amendment of the credit agreement and acquisition, the Company repaid its term loan of $60.0 million and its cash collateral of $61.7 million was released. The Senior Credit Facilities mature five years after the closing of the Senior Credit Facilities and the proceeds thereof were used to pay the consideration in connection with the Merger, to repay GCE’s and Orbis Education’s existing debt, and to pay the fees and expenses relating to the Merger and the financing transactions. The senior secured revolving credit facility is available for general corporate purposes, including permitted acquisitions, working capital and the issuance of letters of credit. All borrowings under the senior secured revolving credit facility will be subject to the satisfaction of customary conditions, including the absence of a default and compliance with representations and warranties. On January 31, 2019, GCE and the other parties to the Credit Agreement entered into a First Amendment (the “First Amendment”) to the Credit Agreement. Under Section 2.16 of the Credit Agreement, GCE had the right, during the period from January 22, 2019 to March 31, 2019 (or such later date as agreed by the administrative agent) to increase the principal amount of the term loan and the aggregate revolving commitments by up to $50,000, from an aggregate of $250,000 to up to an aggregate of $300,000 (subject to certain conditions).

On February 1, 2019, GCE and the parties to the Credit Agreement entered into a First Incremental Facility Amendment (the “First Incremental Facility Amendment”) to the Credit Agreement. Pursuant to the First Incremental Facility Amendment, GCE borrowed an incremental $56,250 principal amount of term loans and increased the aggregate revolving commitments by $18,750, thereby increasing the principal amount of the term loan borrowed to $243,750 and the principal amount of the aggregate revolving commitments to $81,250. No other changes were made to the Credit Agreement. Repayment of Loans. GCE is required to repay the aggregate principal amount of all revolving loans outstanding by the maturity date. The term facility is subject to quarterly amortization of principal, commencing with the fiscal quarter ending June 30, 2019, in equal installments of 5% of the original principal amount of the term facility, which represents $12,188 per quarter. Interest and Fees. The interest rate per annum applicable to loans under the Senior Credit Facilities is LIBOR plus an applicable margin of 2.0% per annum or, at GCE’s option, the base rate plus an applicable margin of 0.75% per annum. LIBOR will be reset at the beginning of each selected interest period based on the LIBOR rate then in effect. The base rate is a fluctuating interest rate equal to the highest of (i) the federal funds effective rate from time to time plus 0.50%, (ii) the prime lending rate announced from time to time by the administrative agent, and (iii) LIBOR (after taking account of any applicable floor) applicable for an interest period of one month plus 1.25%. If LIBOR or the base rate is below zero, then such rate will be equal to zero plus the applicable margin. Prepayments. Voluntary prepayments of the term loan and the revolving loans and voluntary reductions in the unused commitments are permitted in whole or in part, in minimum amounts as set forth in the Credit Agreement governing the Senior Credit Facilities, with prior notice but without premium or penalty. Collateral and Guarantees. The obligations under the Senior Credit Facilities are secured by substantially all of the present and after acquired assets of each of GCE and any subsidiary guarantors (excluding owned and leased real property and certain other assets) (the “Collateral”) including, (a) a perfected first priority pledge of all equity interests of each domestic direct, wholly owned material restricted subsidiary held by GCE, and (b) a perfected first priority security interest in substantially all other tangible and intangible assets of GCE and any subsidiary guarantors (excluding owned and leased real property and certain other assets but including accounts receivable, inventory, equipment, general intangibles, intellectual property and the proceeds of the foregoing). Subject to certain exceptions, the Senior Credit Facilities are unconditionally guaranteed by GCE and its material domestic subsidiaries. Covenants and Other Matters.

The Credit Agreement governing the Senior Credit Facilities also requires GCE, together with its subsidiaries, to comply with certain financial covenants, including a consolidated leverage ratio, a consolidated fixed charge coverage ratio, and a consolidated tangible net worth test. Events of default under the Credit Agreement governing the Senior Credit Facilities include customary events such as a cross-default provision with respect to other material debt and upon a change of control (as defined therein). In addition, an event of default under the Credit Agreement occurs if there is an event of default under GCE’s loan agreement with GCU or if the services agreement between GCE and GCU is terminated.
