[1] On April 5, 2012, the Company, as borrower, and certain of its wholly-owned subsidiaries, as guarantors, entered into a secured revolving credit agreement with a syndicate of four lenders led by Bank of America, N.A., as administrative agent and letter of credit issuer (the "Credit Facility"). The April 5, 2012 agreement, along with subsequent amendments dated June 18, 2013 and December 20, 2013, are collectively referred to as the "Credit Agreement." As of December 31, 2013, the aggregate principal amount available under the Credit Facility was $60 million. Under the terms of the Credit Agreement, amended January 16, 2014, this amount was reduced to $40 million. The Credit Facility may be used to finance capital expenditures and permitted acquisitions, to pay transaction expenses, for the issuance of letters of credit and for general corporate purposes. The Credit Agreement includes a $25 million letter of credit sublimit. The original term of the Credit Facility is 36 months, maturing on April 5, 2015. The Credit Agreement provides that the lenders will receive first priority lien on substantially all of the tangible and intangible non-real property assets of the Company and its subsidiaries as well as a first priority lien on substantially all real property owned by the Company and its subsidiaries and that all net proceeds of future sales of real property by the Company and its subsidiaries be used to prepay revolving loans and permanently reduce the principal amount of revolving loans available under the Credit Facility. Amounts borrowed as revolving loans under the Credit Facility will bear interest, at the Company's option, at either (i) an interest rate based on LIBOR and adjusted for any reserve percentage obligations under Federal Reserve Bank regulations (the "Eurodollar Rate") for specified interest periods or (ii) the Base Rate (as defined in the Credit Agreement), in each case, plus an applicable margin rate as determined under the Credit Agreement. The "Base Rate", as defined under the Credit Agreement, is the highest of (a) the rate of interest announced from time to time by Bank of America, N.A. as its prime rate, (b) the Federal Funds rate plus 0.50% and (c) a daily rate equal to the one-month LIBOR rate plus 1.0%. Pursuant to the Credit Agreement, the margin interest rate is subject to adjustment within a range of 2.50% to 6.00% based upon changes in the Company's consolidated leverage ratio and depending on whether the Company has chosen the Eurodollar Rate or the Base Rate option. Letters of credit will require a fee equal to the applicable margin rate multiplied by the daily amount available to be drawn under each issued letter of credit plus an agreed upon fronting fee and customary issuance, presentation, amendment and other processing fees associated with letters of credit. At September 30, 2014, the Company had outstanding letters of credit aggregating $5.3 million, which were primarily comprised of letters of credit for the Department of Education, or DOE, matters and real estate leases. The Credit Agreement contains representations, warranties and covenants including consolidated adjusted net worth, consolidated leverage ratio, consolidated fixed charge coverage ratio, minimum financial responsibility composite score, cohort default rate and other financial covenants, certain restrictions on capital expenditures as well as affirmative and negative covenants and events of default customary for facilities of this type. In addition, the Company is paying fees to the lenders that are customary for facilities of this type. As of September 30, 2014 the Company is in compliance with all financial covenants. During the three months ended September 30, 2014 the Company had net repayments of $7.5 under the Credit Facility during the three months ended September 30, 2014. The Company had $7.5 million outstanding under the Credit Facility as of September 30, 2014. The interest rates on these borrowings ranged from 4.2% to 7.3%. The Company had $54.5 million outstanding under the Credit Agreement as of December 31, 2013 which was repaid on January 3, 2014. The interest rate on this borrowing was 7.3%.

[2] The Company completed a sale and a leaseback of several facilities on December 28, 2001. The Company retains a continuing involvement in the lease and, as a result, it is prohibited from utilizing sale-leaseback accounting. Accordingly, the Company has treated this transaction as a finance lease. The lease expires on December 31, 2016.

[3] In 2009, the Company assumed real estate capital leases in Fern Park, Florida and Hartford, Connecticut. These leases bear interest at 8% and expire in 2032 and 2031, respectively.
