FIRST AMENDMENT TO CREDIT AGREEMENT

This First Amendment to Credit Agreement (herein, the “Amendment”) is entered into as of April 19, 2004, between Nobel Learning Communities, Inc., a Delaware corporation (“Borrower”), and Harris Trust and Savings Bank (“HTSB”), as sole Lender on the date hereof and as Administrative Agent for the Lenders.

PRELIMINARY STATEMENTS

A. The Borrower, the Guarantors, and HTSB entered into a certain Credit Agreement, dated as of February 20, 2004 (referred to herein as the “Credit Agreement”). All capitalized terms used herein without definition shall have the same meanings herein as such terms have in the Credit Agreement.

B. The Borrower has requested that HTSB extend the deadline by which the Borrower is to sell its real property located in Alpharetta, Georgia in order to exclude Capital Expenditures in connection therewith from certain restrictions set forth in the Credit Agreement, amend the restriction on changing the Borrower’s fiscal year end, and make certain other amendments to the Credit Agreement, and HTSB is willing to do so under the terms and conditions set forth in this Amendment.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

SECTION 1. AMENDMENTS.

Subject to the satisfaction of the conditions precedent set forth in Section 2 below, the Credit Agreement shall be and hereby is amended as follows:

1.1. The definition of “Capital Expenditures” set forth in Section 5.1 of the Credit Agreement shall be amended and restated in its entirety to read as follows:

“Capital Expenditures” means, with respect to any Person for any period, the aggregate amount of all expenditures (whether paid in cash or accrued as a liability) by such Person during that period for the acquisition or leasing (pursuant to a Capital Lease) of fixed or capital assets or additions to property, plant, or equipment (including replacements, capitalized repairs, and improvements) which should be capitalized on the balance sheet of such Person in accordance with GAAP, but specifically excluding Capital Expenditures incurred in connection with the purchase of certain real property located in Alpharetta, Georgia (the “Alpharetta Property”), as long as such real property is sold by the Borrower not later than April 30, 2005 in a transaction pursuant to which the Borrower receives and pays to the Administrative Agent as a prepayment on the Obligations Net Cash Proceeds of not less

than $1,000,000; provided, however, that if the Borrower fails to sell the Alpharetta Property by April 30, 2005, then all Capital Expenditures incurred in connection with the purchase of the Alpharetta Property shall be included in the Borrower’s Capital Expenditures for the first fiscal quarter of 2005 of the Borrower.

1.2. In order to fix a scrivener’s error, the word “to” immediately following “within 30 days after” set forth in the first sentence of Section 8.5(f) shall be deleted.

1.3. Subsection (i) of Section 8.8 of the Credit Agreement shall be amended and restated in its entirety to read as follows:

(i) Liens granted in favor of EAB Leasing Corp. on Property of the Borrower and its Subsidiaries to secure an equipment lease, provided that, by June 7, 2004 and without the expenditure by the Borrower and its Subsidiaries of more than $1,500,000, either (x) the holder of such Liens has agreed in writing to modify their scope so that the Property encumbered thereby shall not extend beyond the leased equipment and certain proceeds thereof acceptable to the Administrative Agent and has filed a UCC amendment reflecting such modification in all necessary jurisdictions, or (y) such Liens have been terminated and released by the holder thereof; and

1.4. Section 8.16 of the Credit Agreement shall be amended and restated in its entirety to read as follows:

Section 8.16. No Changes in Fiscal Year. The fiscal year of the Borrower and its Subsidiaries ends on June 30 of each year; and the Borrower shall not, nor shall it permit any Subsidiary to, change its fiscal year or the corresponding fiscal quarters from their present basis; provided, however, that the Borrower may change such fiscal year to end on the Saturday closest to June 30 of each year (whether such Saturday is before or after June 30), with corresponding changes to its fiscal quarter ending dates.

SECTION 2. CONDITIONS PRECEDENT.

Upon the satisfaction of all of the following conditions precedent, this Amendment shall become effective on and as of the date first above written to the same extent as if it had been entered into on such date:
