THIS FIRST AMENDMENT TO REVOLVING CREDIT AGREEMENT (this “Amendment”), is made and entered into as of December 11, 2012, by and among HEICO CORPORATION, a Florida corporation (the “Borrower”), the several banks and other financial institutions from time to time party hereto (collectively, the “Lenders”) and SUNTRUST BANK, in its capacity as Administrative Agent for the Lenders (the “Administrative Agent”), as issuing bank (the “Issuing Bank”) and as swingline lender (the “Swingline Lender”).

WHEREAS, the Borrower, the Lenders and the Administrative Agent are parties to a certain Revolving Credit Agreement, dated as of December 14, 2011 (as amended, restated, supplemented or otherwise modified from time to time, the “Credit Agreement”; capitalized terms used herein and not otherwise defined shall have the meanings assigned to such terms in the Credit Agreement), pursuant to which the Lenders have made certain financial accommodations available to the Borrower;

WHEREAS, the Borrower has requested that the Lenders and the Administrative Agent amend certain provisions of the Credit Agreement, and subject to the terms and conditions hereof, the Lenders are willing to do so;

NOW, THEREFORE, for good and valuable consideration, the sufficiency and receipt of all of which are acknowledged, the Borrower, the Lenders and the Administrative Agent agree as follows:

1.Amendments.

(a) Section 1.1 of the Credit Agreement is amended by replacing the definition of “Revolving Commitment Termination Date” in its entirety with the following definition:

“Revolving Commitment Termination Date” shall mean the earliest of (i) December 14, 2017, as such date may be extended pursuant to the terms of Section 2.25, (ii) the date on which the Revolving Commitments are terminated pursuant to Section 2.7 and (iii) the date on which all amounts outstanding under this Agreement have been declared or have automatically become due and payable (whether by acceleration or otherwise).

(b)    Section 2.25 of the Credit Agreement is hereby amended by replacing the first sentence of subsection (b) of such Section in its entirety with the following:

If all of the Lenders consent in writing to any such request in accordance with subsection (a) of this Section 2.25, the Revolving Commitment Termination Date shall, effective as at such next Anniversary Date (or such other date as the Lenders shall agree in such writing) (the “Extension Date”), be extended for one calendar year from the then scheduled Revolving

Commitment Termination Date; provided that on each Extension Date, no Default or Event of Default shall have occurred and be continuing, or shall occur as a consequence thereof.    

2.Conditions to Effectiveness of this Amendment. Notwithstanding any other provision of this Amendment and without affecting in any manner the rights of the Lenders hereunder, it is understood and agreed that this Amendment shall not become effective, and the Borrower shall have no rights under this Amendment, until the Administrative Agent shall have received (i) an amendment fee in the amount of 0.05% of the Revolving Commitments of those Lenders executing this Amendment, to be applied pro rata among such Lenders, (ii) such other fees as the Borrower has previously agreed to pay the Administrative Agent or any of its affiliates in connection with this Amendment, (iii) reimbursement or payment of the costs and expenses of the Administrative Agent incurred in connection with this Amendment or the Credit Agreement (including reasonable fees, charges and disbursements of King & Spalding LLP, counsel to the Administrative Agent), and (iv) each of the following documents:

(a)     executed counterparts to this Amendment from the Borrower, each of the Guarantors and Lenders constituting at least the Required Lenders; and

(b)    a certificate of the Secretary or Assistant Secretary of the Borrower, attaching and certifying copies of resolutions of its board of directors, authorizing the execution, delivery and performance of the Amendment, certifying the name, title and true signature of each officer of the Borrower executing the Amendment and confirming that the articles of incorporation and bylaws have not changed since the Closing Date.
