This Letter also confirms that, subject to the terms and conditions of this letter, the Required Lenders hereby consent to the sale by Imonics Corporation of the Excess Imonics Equipment (and all of the Lenders' and the Agent's Liens on such Collateral under the Security Documents shall be released upon the sale thereof), provided that (i) the Net Proceeds of such sale are applied in accordance with Section 2.06 of the Credit Agreement (and, pending such application, the Lenders' and the Agent's Liens shall attach thereto pursuant to the Security Documents and such proceeds shall constitute Collateral for the Obligations) and (ii) no Default or Event of Default exists at the time of such sale. Please note that this letter (and the waivers and consent confirmed herein) shall not become effective unless and until (a) the aforesaid waiver fee has been paid and (b) this letter has been signed by the Required Lenders and this letter has been accepted and agreed to by Borrower, in each case by such person's signing a copy of this letter in the appropriate space indicated below and returning the same to the Agent's counsel (which may be done by telecopy and in counterparts). 3 Please note that the waivers and consent confirmed in this letter relate solely to the specific covenants, dates and time periods described above and nothing in this letter is intended (or shall be construed) to constitute a waiver of or a consent to a departure from any other covenants in the Credit Agreement.
