     Re: Amendment to Private Shelf Agreement

Ladies and Gentlemen:

     Reference is made to that certain Private Shelf Agreement dated as of November 27, 1996 (as amended prior to the date hereof, the “Agreement”) between Applied Industrial Technologies, Inc., an Ohio corporation formerly known as Bearings, Inc. (the “Company”), and Prudential Investment Management, Inc. (“Prudential”), pursuant to which the Company issued and sold and Prudential purchased the Company’s 6.60% Series B Notes in the original aggregate principal amount of $50,000,000, due December 8, 2007. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to such terms in the Agreement.

     Pursuant to the request of the Company and in accordance with the provisions of paragraph 11C of the Agreement, the parties hereto agree as follows:

     SECTION 1. Amendment. From and after the date this letter becomes effective in accordance with its terms, the Agreement is amended as follows:

     1.1 The first sentence of Paragraph 1 of the Agreement is amended by deleting the phrase “no more than twelve (12) years after the issuance thereof, to have an average life, in the case of each Note so issued, of no more than ten (10) years after the date of original issuance thereof,” and substituting therefore the following:

“no more than fifteen (15) years after the issuance thereof, to have an average life, in the case of each Note so issued, of no more than twelve (12) years after the date of original issuance thereof,”

     1.2 Paragraph 2B of the Agreement is amended to delete in its entirety clause (i) thereof and to substitute therefor the following: “(i) March 30, 2010 and”.

NOTWITHSTANDING THE FOREGOING, THIS AMENDMENT AND THE AGREEMENT HAVE BEEN ENTERED INTO ON THE EXPRESS UNDERSTANDING THAT NEITHER PRUDENTIAL NOR ANY PRUDENTIAL AFFILIATE SHALL BE OBLIGATED TO MAKE OR ACCEPT OFFERS TO PURCHASE PRIVATE SHELF NOTES, OR TO QUOTE RATES, SPREADS OR OTHER TERMS WITH RESPECT TO SPECIFIC PURCHASES OF PRIVATE SHELF NOTES, AND THE FACILITY SHALL IN NO WAY BE CONSTRUED AS A COMMITMENT BY PRUDENTIAL OR ANY PRUDENTIAL AFFILIATE.

     1.4 Paragraph 2E of the Agreement is amended to delete in its entirety the fifth sentence thereof. For clarity, the fifth sentence hereby deleted begins with “In the event” and ends with “determined by Prudential”.

     1.5 Paragraph 2H(2) of the Agreement is amended (i) to delete the first sentence thereof up to but not including the equation “(BEY — MMY) X DTS/360 X Full Price” and substituting therefore the following:

     “If the closing of the purchase and sale of any Accepted Note is delayed for any reason beyond the original Private Shelf Closing Day for such Accepted Note, the Company will pay to Prudential (a) on the Cancellation Date or actual closing date of such purchase and sale and (b) if earlier, the next Business Day following 90 days after the Acceptance Day for such Accepted Note and on each Business Day following 90 days after the prior payment hereunder, a fee (herein called the “Delayed Delivery Fee”) calculated as follows:”
