We have acted as special Nevada counsel to Spectrum Manufacturing, Inc., a Nevada corporation (the “Company”), in connection with the Registration Statement on Form S-1 filed on October 18, 2010, (the “Registration Statement”) by Accellent Inc., a Maryland corporation (“Accellent”), and the guarantors named therein (the “Guarantors”) with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), relating to the sale by the selling security holders named in the Registration Statement of $33,136,000 aggregate principal amount of 8 ³/8% Senior Secured Notes due 2017 (the “Securities”) and the issuance by the Guarantors of guarantees (the “Guarantees”) with respect to the Securities (the “Transaction”). The Securities and the Guarantees will be issued under an indenture dated as of January 29, 2010 (the “Indenture”), among Accellent, the Guarantors and The Bank of New York Mellon, as trustee (“Trustee”).

In connection with this opinion, and as such counsel, we have examined and relied upon, but have not prepared, originals or copies of the following documents (the “Documents”):

Item F through I above are referred to herein as the “Organizational Documents.” In addition, in our capacity as special Nevada counsel for the Company, we have also examined such other documents, matters, statutes, ordinances, published rules and regulations, published judicial and governmental decisions interpreting or applying the same and other official interpretations as we deemed applicable in connection with this letter.

As used herein all references to “Nevada Laws” shall mean any laws of the State of Nevada, as in effect on the date of this letter.

In rendering the opinions set forth below, we have relied, with your permission, on the representations contained in the Documents, and we have assumed the following:

a) Except for the Company, each of the parties to the Documents has duly and validly executed and delivered each such instrument, document, and agreement to be executed in connection with the Transaction to which such party is a signatory, and the obligations of each party, including the Company, set forth in the Operative Documents are its legal, valid, and binding obligations, enforceable in accordance with their respective terms.

b) Each person, other than the Company, executing any of the Documents, whether individually or on behalf of an entity, is duly authorized to do so.

c) All signatures on the Documents are genuine.

d) All Documents submitted to us as originals are authentic; all Documents submitted to us as certified or photostatic copies or as unexecuted forms conform to the original documents; all public records reviewed are accurate and complete; and the certificates and other documentation issued or prepared by governmental authorities or officers of the Company are accurate as of the date of this letter even though they may have been signed or issued on an earlier or later date.

e) The Trustee or its agents have obtained physical possession of the original executed Indenture.

Based on the foregoing, and on such other documents and information as the undersigned deems necessary for the purpose of issuing this letter, and subject to the assumptions above and the qualifications and limitations hereinafter set forth, it is our opinion that as of the date of this letter:

1. The Company has been duly authorized to execute and deliver the Indenture in accordance with Nevada Laws and, at such time and based solely on the Good Standing Certificate, the Company was validly existing and in good standing under Nevada Laws. The Indenture has been duly executed by the Company and delivered by the Company to the Trustee.

2. The execution, delivery and performance by the Company of the Indenture, the Securities and the Guarantees do not and will not result in a violation of any law, statute or regulation of the State of Nevada or the Organizational Documents.

3. The Guarantees have been duly authorized by the Company.

In addition to the assumptions set forth above, the opinions set forth above are also qualified as follows:

(i) The effect of applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, suretyship, moratorium and other similar laws relating to or affecting the rights of creditors generally.

(ii) The effect of the exercise of judicial discretion in accordance with general principles of equity (whether applied by a court of law or of equity).

(iii) The implied covenant of good faith and fair dealing.

(iv) We express no opinion with respect to the enforceability of any Documents as no such opinions have been requested from us.

(v) We express no opinion as to the laws of any jurisdiction other than the laws of the State of Nevada. The opinions expressed above concern only the effect of the laws, excluding the principles of conflict of laws, of the State of Nevada as currently in effect.

(vi) We assume no obligation to supplement this letter if any applicable laws change after the date of this letter with possible retroactive effect, or if any facts or events occur or come to our attention after the date of this letter that might change any of the opinions expressed above.
