Ladies and Gentlemen:

     Reference is made to the Master Note Purchase Agreement dated as of September 28, 2006 (the “Note Agreement”) among Encore Wire Limited, a Texas limited partnership (the “Company”), Encore Wire Corporation, a Delaware corporation (the “Parent”), and each of the Purchasers named in Schedule A thereto pursuant to which the Company issued $55,000,000 aggregate principal amount of its Floating Rate Senior Notes, Series 2006-A, due September 30, 2011 (the “Notes”). You are referred to herein individually as a “Holder” and collectively as the “Holders.” Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to them in the Note Agreement.

     The Company and the Parent have requested waivers of Sections 9.5 and 10.5 of the Note Agreement in connection with the merger of the Company into EWC GP Corp., a Delaware corporation and a Restricted Subsidiary (“GP Corp.”), and the subsequent merger of GP Corp. into the Parent (surviving entity). In connection with this transaction EWC LP Corp., a Delaware corporation and a Restricted Subsidiary, is also merging into GP Corp. prior to the merger of GP Corp. into the Parent. The Company and the Parent have made a similar request of the banks in respect of the Credit Agreement. The Holders are willing to grant the waiver under such section of the Note Agreement on the terms and conditions set forth herein.

     In consideration of the premises and for good and valuable consideration, the receipt and sufficiency of which are acknowledged, the Parent, the Company and the Holders agree as follows:

1. WAIVER

     The Holders hereby waive any Default or Event of Default under Sections 9.5 and 10.5 of the Note Agreement resulting from the merger of the Company into GP Corp. and the subsequent merger of GP Corp. into the Parent (surviving entity). This waiver is limited to its terms, is conditioned upon an identical waiver by the banks under the Credit Agreement, and shall not constitute a waiver of any other term, condition, representation or covenant under the Note Agreement or any of the other agreements, documents or instruments executed and delivered in connection therewith.

2. ISSUANCE OF NEW NOTES

     The Holders shall receive new Notes executed and delivered by the Parent, as successor in interest to the Company, after surrender by the Holders of their respective Notes that are currently issued in the name of the Company.

3. REAFFIRMATION; REPRESENTATIONS AND WARRANTIES

     3.1. Reaffirmation of Note Agreement. The Parent reaffirms its agreement to comply with each of the covenants, agreements and other provisions of the Note Agreement and the Notes, including the waivers of Sections 9.5 and 10.5 effected by this Waiver.

     3.2. Note Agreement. The Parent and the Company represent and warrant that the representations and warranties contained in the Note Agreement are true and correct as of the date hereof, except (a) to the extent that any of such representations and warranties specifically relate to an earlier date, (b) for such other matters as have been previously disclosed in writing by the Parent and the Company (including in financial statements and notes thereto) to the Holders and (c) for other changes that, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

     3.3. No Default or Event of Default. After giving effect to the transactions contemplated hereby, there will exist no Default or Event of Default.

     3.4. Authorization.

     3.4.1. Parent. The execution, delivery and performance by the Parent and the Company of this Waiver have been duly authorized by all necessary corporate action and, except as provided herein, do not require any registration with, consent or approval of, notice to or action by, any Person (including any Governmental Authority) in order to be effective and enforceable. The Note Agreement and this Waiver each constitute the legal, valid and binding obligations of the Parent and the Company, enforceable in accordance with their respective terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

2

     3.4.2. Subsidiary Guarantor. The execution, delivery and performance by the Subsidiary Guarantor of the Reaffirmation of Subsidiary Guaranty have been duly authorized by all necessary corporate action and, except as provided herein, do not require any registration with, consent or approval of, notice to or action by, any Person (including any Governmental Authority) in order to be effective and enforceable. The Subsidiary Guaranty constitutes the legal, valid and binding obligations of such Subsidiary Guarantor, enforceable in accordance with their respective terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

4. EFFECTIVE DATE

     This Waiver shall become effective as of June 29, 2007 upon the satisfaction of the following conditions:

Failure of the Holders to receive such an opinion by such date shall be an Event of Default under the Note Agreement.

     4.5. Fees of Special Counsel. The Parent shall have paid all fees and expenses of special counsel to the Holders.
