[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, December 20, 2013, December 29, 2014 and March 4, 2015, 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. Effective January 16, 2014, this amount was reduced to $40 million. Effective January 15, 2015, this amount was reduced to $20 million. The revolving commitments available for use other than for the issuance of letters of credit under the Credit Facility have been reduced to $12 million and, during the period commencing on December 1, 2015 through January 15, 2016. During the period commencing on December 1, 2015 through January 15, 2016 the Company is required to reduce the outstanding revolving loans, other than letters of credit obligations, to $0. 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 which is reduced to $20 million effective January 15, 2015. Borrowings under the Credit Facility are secured by a first priority lien on substantially all of the tangible and intangible assets of the Company and its subsidiaries including real estate. The term of the Credit Facility was 36 months, maturing on April 5, 2015. The Credit Facility was extended on March 4, 2015 for an additional 12 months with a new expiration date of April 5, 2016. 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 under the Credit Facility shall continue to bear interest, at the Company's option, at either (i) an interest rate based on LIBOR (or the rate of 1.00%, if greater) 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 under the Credit Facility), in each case, plus an applicable margin rate as determined under the Credit Agreement. The "Base Rate", as defined under the Credit Facility, 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 0.5% and (c) a daily rate equal to the one-month LIBOR rate plus 1.0%. The Fourth Amendment re-sets the margin interest rate for (a) Base Rate loans as (i) 11.0% from March 4, 2015 through April 15, 2015, (ii) 14.0% from April 16, 2015 through May 31, 2015 and (iii) 17.0% from June 1, 2015 and thereafter and (b) Eurodollar Rate loans as (i) 12.0% from March 4, 2015 through April 15, 2015, (ii) 15.0% from April 16, 2015 through May 31, 2015 and (iii) 18.0% from June 1, 2015 and thereafter. The Company is required to pay on a quarterly basis a commitment fee equal to the amount of the then unused availability under the Credit Facility multiplied by (i) 5.0%, from March 4, 2015 through April 15, 2015, (ii) 6.0%, from April 16, 2015 through May 31, 2015 and (iii) 7.0% from June 1, 2015 and thereafter. 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. The Company paid an amendment fee of $0.2 million. Also, the Company is required to pay as additional amendment fees the following amounts on the following dates: (i) 0.5% of the revolving commitments outstanding on April 16, 2015; (ii) 0.5% of the revolving commitments outstanding on June 1, 2015; (iii) 1.0% of the revolving commitments outstanding on September 30, 2015; and (iv) 1.0% of the revolving commitments outstanding on December 31, 2015; provided, however, that no additional amendment fee will be due and owing on any such date in the event that the Credit Facility has been terminated, and all amounts due and owing under the Credit Facility repaid in full, on or prior to such date. At March 31, 2015, the Company had outstanding letters of credit aggregating $7.1 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 customary 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 March 31, 2015 the Company is in compliance with all financial covenants. During the three months ended March 31, 2015 the Company had net repayments of $30.0 million under the Credit Facility. The Company had no amounts outstanding under the Credit Facility as of March 31, 2015. The interest rates on borrowings ranged from 7.25% to 14.25%. The Company had $30.0 million outstanding under the Credit Agreement as of December 31, 2014 which was repaid on January 3, 2014. The interest rate on this borrowing was 7.25%.

[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.
