“Securities Act” shall mean the Securities Act of 1933, and any amendments or modifications, or successor legislation, thereto adopted, and all regulations, rules or other laws enacted or adopted pursuant thereto.

“Warrant Certificate” shall mean any certificate representing Warrants.

“Warrant Registry” means the official record maintained by the Corporation in which are recorded, with respect to each Warrant Certificate issued by the Corporation: the date of issuance, the name and address of the original Holder, the name and address of each subsequent transferee of such original Holder, and the number identifying, such Warrant Certificate.

“Warrant Shares” shall have the meaning given to it in the face page hereof.

“Warrants” shall mean the Warrants represented by this Warrant Certificate.

Each Warrant evidenced hereby may be exercised by the Holder at any time on the Exercise Date, upon the terms and subject to the conditions set forth herein, by delivery to the Corporation of a completed Notice of Exercise in the form attached as Schedule A hereto. A Warrant shall be deemed to have been exercised immediately prior to the close of business on the Exercise Date and the person entitled to receive shares of restricted common stock of the Corporation deliverable upon such exercise shall be treated for all purposes as the Holder of a Warrant Share upon the exercise of the applicable Warrant as of the close of business on the Exercise Date. Promptly following, and in any event within ten (10) business days after, the date on which the Corporation first receives clearance of all funds received in payment of the Purchase Price pursuant to this Warrant Certificate, the Corporation shall cause to be issued and delivered to the person or persons entitled to receive the same, a certificate or certificates evidencing the issuance to such Holder of the applicable number of Warrant Shares (plus a Warrant Certificate for any remaining issued but unexercised Warrants of the Holder). Notwithstanding the foregoing sentence, in the event that any registration or qualification (or filing for exemption from any such requirements) is required prior to the issuance of such Warrant Shares

by the Corporation in accordance with Section 3(b) below, then the obligation to deliver any such certificates shall arise only upon completion of such requirements and at such time as the Corporation may lawfully do so.

Upon the exercise of the Warrants represented hereby, if the Corporation so requests, the Holder shall certify to the Corporation that it is not exercising such Warrants with a view to distribute the Warrant Shares in violation of the Securities Act, and shall provide such other investor representations as the Corporation may require to confirm the ability of the Corporation to rely upon the exemption from registration under the Securities Act which applies to the distribution of Warrant Shares at the time of such distribution.

The Corporation covenants that it will at all times reserve and keep available out of its authorized Common Stock, solely for the purpose of issue upon the valid exercise of Warrants, such number of Warrant Shares as shall then be issuable upon the exercise of all Warrants then outstanding. The Corporation covenants that all shares of Common Stock which shall be issuable upon exercise of the Warrants shall, at the time of delivery, be duly and validly issued, fully-paid, non- assessable and free from all taxes, liens and charges with respect to the issuance thereof (other than those which the Corporation shall promptly pay or discharge, or any liens created thereon by the Holder thereof and/or any predecessor of such Holder).

The Corporation shall not be obligated to deliver any Warrant Shares pursuant to the exercise of the Warrants represented hereby unless and until a registration statement under the Securities Act and/or under any applicable state securities laws and regulations, with respect to such securities is effective, or an exemption from such registration is available to the Corporation at the time of such exercise. The Corporation covenants that if any Warrant Shares reserved for the purpose of exercise of Warrants hereunder require registration with, or approval of, any governmental authority under any federal or state securities law before such securities may be validly issued or delivered upon such exercise, then the Corporation will in good faith and as expeditiously as reasonably possible, endeavor to secure such registration or approval. However, in the event that this Warrant Certificate represents Warrants which have been transferred by an initial holder thereof, the Warrants represented hereby may not be exercised by, nor shares of Common Stock issued

to, the Holder hereof in any state in which such exercise and issuance would be unlawful.

If at any time from the date hereof until the earliest to occur of (A) the date as of which all the Warrant Shares may be sold by the Holder without regard to the volume limitations set forth in Rule 144(e) under the Securities Act, and (B) such date as of which all the Warrant Shares held by the Holder have been sold, and there is not an effective registration statement covering all of the Warrant Shares, the Corporation shall determine to prepare and file with the United States Securities and Exchange Commission a registration statement relating to an offering for its own account or the account of others under the Securities Act, of any of its equity securities (other than on Form S-4 or Form S-8 under the Securities Act, or their then equivalents, relating to equity securities to be issued solely in connection with any acquisition of any entity or business, or equity securities issuable in connection with stock incentive or other employee benefit plans), then the Corporation shall send to the Holder written notice of such determination and, if within fifteen days after receipt of such notice, the Holder shall so request in writing, the Corporation shall include in such registration statement all or any part of the Warrant Shares the Holder requests to be registered; provided that: (i) the Corporation shall not be required to register any Warrant Shares pursuant to this Section that are eligible for resale pursuant to Rule 144(k) promulgated under the Securities Act; and (ii) the Corporation shall not be required to register any Warrant Shares until after the Holder has exercised the Warrant.

The Corporation shall pay all documentary, stamp or similar taxes and other governmental charges that may be imposed with respect to the issuance of the Warrants, or the issuance or delivery of any shares of Common Stock upon exercise of the Warrants; provided, however, that if the shares of Common Stock are to be delivered in a name other than the name of the Holder hereof, then no such delivery shall be made unless the person requesting the same has paid to the Corporation the amount of transfer taxes or charges incident thereto, if any.

Subject to the provisions of this Warrant Certificate and applicable law, in the event the Corporation shall, at any time or from time to time after the date hereof, issue any shares of Common Stock as a stock dividend to the holders of Common Stock, or subdivide or combine the outstanding shares of Common Stock into a greater or lesser number of shares (any such sale, issuance, subdivision or combination being herein called a “Change of Shares”), then, and thereafter upon each further Change of Shares, the Purchase Price in effect immediately prior to such Change of Shares shall be reduced, but in no event increased, to a price (the “Adjusted Purchase Price”) determined by multiplying the Purchase Price in effect immediately prior to such Change of Shares by a fraction, the numerator of which shall be the sum of the number of shares of Common Stock outstanding immediately prior to the issuance of such additional shares plus the number of shares of Common Stock which the aggregate consideration received by the Corporation would purchase at such Purchase Price, and the denominator of which shall be the sum of the number of shares of Common Stock outstanding immediately after the issuance of such additional shares. Such adjustment to the Purchase Price shall be made successively whenever an issuance is made after a Change of Shares has occurred.

Upon each adjustment of the Purchase Price pursuant to this Section 5(a), the total number of shares of Common Stock purchasable upon the exercise of each Warrant shall become (subject to the provisions contained in Section 5(b) hereof) such number of shares (calculated to the nearest tenth) purchasable at the Purchase Price in effect immediately prior to such adjustment multiplied by a fraction, the numerator of which shall be the Purchase Price in effect immediately

prior to such adjustment and the denominator of which shall be the applicable Adjusted Purchase Price (rounded to the nearest whole number of shares). No fractional shares shall be issued or called for as a result of any adjustment made hereunder.

The Corporation may elect, at its sole discretion, upon any adjustment of the Purchase Price hereunder, to adjust the number of Warrants outstanding, in lieu of adjustment of the number of Warrant Shares purchasable upon the exercise of each Warrant as hereinabove provided, so that each Warrant outstanding after such adjustment shall represent the right to purchase one Warrant Share. Each Warrant held of record prior to such adjustment of the number of Warrants shall become that number of Warrants (calculated to the nearest tenth) determined by multiplying the number one by a fraction, the numerator of which shall be the Purchase Price in effect immediately prior to such adjustment and the denominator of which shall be the Adjusted Purchase Price. Upon each adjustment of the number of Warrants pursuant to this Section 5(b), the Corporation shall, as promptly as practicable, cause to be distributed to each Holder of Warrant Certificates, on the date of such adjustment, Warrant Certificates evidencing the adjusted number of Warrants to which such Holder shall be entitled as a result of such adjustment or, at the sole option of the Corporation, cause to be distributed to such Holder in substitution and replacement for the Warrant Certificates held by him prior to the date of adjustment, and upon surrender thereof, (if required by the Corporation) new Warrant Certificates evidencing the aggregate number of Warrants to which such Holder shall be entitled after such adjustment.

In case of any reclassification, capital reorganization or other change of outstanding shares of Common Stock, or in case of any consolidation or merger of the Corporation with or into another corporation (other than a consolidation or merger in which the Corporation is the continuing corporation and which does not result in any reclassification, capital reorganization or other change of outstanding shares of Common Stock), or in case of any sale or conveyance to another corporation of all, or substantially all, of the property of the Corporation (other than a sale/leaseback, mortgage or other financing transaction), the Corporation shall cause effective provision to be made so that each holder of a Warrant then outstanding shall have the right thereafter, by exercising such Warrant, to purchase the kind and number of shares of stock or other securities or property (including cash) receivable upon such reclassification, capital reorganization or other change, consolidation, merger, sale or conveyance by a holder of the number of Warrant

Shares that might have been purchased upon exercise of such Warrant immediately prior to such reclassification, capital reorganization or other change, consolidation, merger, sale or conveyance. Any such provision shall include provision for adjustments that shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 5 upon a Change of Shares. The Corporation shall not effect any such consolidation, merger or sale without the written consent of Holders of a majority of the Warrants then outstanding, unless prior to or simultaneously with the consummation thereof the successor (if other than the Corporation) resulting from such consolidation or merger or the corporation purchasing assets or other appropriate corporation or entity shall assume, by written instrument executed and delivered to the Corporation, the obligation to deliver to the holder of each Warrant such substitute warrants, shares of stock, securities or assets as, in accordance with the foregoing provisions, such Holders may be entitled to purchase, and the other obligations of the Corporation set out in this Certificate. The foregoing provisions shall similarly apply to successive reclassifications, capital reorganizations and other changes of outstanding shares of Common Stock and to successive consolidations, mergers, sales or conveyances.

Irrespective of any adjustments or changes in the Purchase Price or the number of Warrant Shares purchasable upon exercise of the Warrants, all Warrant Certificates issued (whether prior to or subsequent to any event causing an adjustment thereof) shall continue to express the Purchase Price per share, and the number of shares purchasable thereunder as originally expressed in the Warrant Certificate initially issued to any Holder.

After each adjustment of the Purchase Price pursuant to this Section 5, the Corporation will promptly prepare a certificate signed by the Chairman or Chief Executive Officer, and attested by the Secretary or an Assistant Secretary, of the Corporation setting forth: (i) the Purchase Price as so adjusted, (ii) the number of shares of Common Stock purchasable upon exercise of each Warrant after such adjustment or, if the Corporation shall have elected to adjust the number of Warrants, the number of Warrants to which the Holder of each Warrant shall then be entitled, and (iii) a brief statement of the facts accounting for such adjustment. The Corporation will promptly cause a brief summary thereof to be sent by ordinary first class mail to each Holder of Warrants at his or her last address as it shall appear on the registry books of the Corporation. No failure to mail such notice nor any defect therein nor in the mailing thereof shall affect the validity thereof. The affidavit of the Secretary or an Assistant

Secretary of the Corporation that such notice has been mailed shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

As used in this Section 5, references to “Common Stock” shall mean and include all of the Corporation’s Common Stock authorized on the date hereof and shall also include any capital stock of any class of the Corporation thereafter authorized which shall not be limited to a fixed sum or percentage in respect of the rights of the holders thereof to participate in dividends and in the distribution of assets upon the voluntary liquidation, dissolution or winding up of the Corporation; provided, however, that “Warrant Shares” shall include only shares of such class designated in the Corporation’s Certificate of Incorporation as Common Stock on the date hereof or (i) in the case of any reclassification, change, consolidation, merger, sale or conveyance of the character referred to in Section 5(c) hereof, the stock, securities or property provided for in such section, or (ii) in the case of any reclassification or change in the outstanding shares of Common Stock issuable upon exercise of the Warrants as a result of a subdivision or combination or consisting of a change in par value, or from par value to no par value, or from no par value to par value, such shares of Common Stock as so reclassified or changed.

Any determination as to whether an adjustment in the Purchase Price in effect hereunder is required pursuant to this Section 5, or as to the amount of any such adjustment, if required, shall be binding upon all holders of Warrants and the Corporation if made in good faith by the Board of Directors of the Corporation. For purposes of this Section 5(g), the Corporation’s Board of Directors shall be deemed to have acted in good faith if it makes any such decision in reliance upon advice of its legal counsel and/or another independent professional hired to advise the Board on such matters.

Neither the Warrants represented by this Warrant Certificate nor the Warrant Shares to be issued upon exercise of the Warrants have been registered under the Securities Act or any state securities laws. Accordingly, neither the Warrants nor the Warrant Shares may be offered, sold or otherwise transferred in the United States or to or for the account or benefit of a U.S. Person or a person in the United States, unless registered under the U.S. Securities Act and applicable state securities laws, or an exemption from registration is available. Except as otherwise provided in this Section 6, each certificate evidencing the issuance of Warrant Shares (whether issued in the

Except as otherwise provided in this Section 6, each Warrant Certificate shall be stamped or otherwise imprinted with a legend in substantially the following form:

The legend requirements of Sections 6(a) and 6(b) above shall terminate as to any particular Warrant or Warrant Share: (i) when and so long as such security shall have been effectively registered under the Securities Act and is disposed of pursuant thereto; or (ii) when the Company shall have received an opinion of counsel reasonably satisfactory to it that such shares may be sold to the public without registration thereof under the Securities Act. Whenever the legend requirements imposed by this Section 6 shall terminate as to any Warrant Share, as hereinabove provided, the Holder hereof shall be entitled to receive from the Corporation, at the Corporation’s expense, a new certificate representing such Warrant Shares and not bearing the restrictive legend set forth in Section 6(a).

is an “accredited investor” as defined in Rule 501 under the Securities Act of 1933, as amended (the “Securities Act”);

Auramet hereby acknowledges and agrees that:

Each Warrant shall be exercisable until 5:00 p.m. (Tucson time) on September 30, 2008, and shall entitle the holder thereof to purchase one share of Borrower’s common stock (each a “Warrant Share” and together with the “Warrants” the “Securities”) at an exercise price that shall be equal to the average of the closing prices of the Borrower’s common stock on the Pink Sheets LLC during the twenty trading days immediately precedingSeptember 30, 2006;

applicable state securities laws, or unless an exemption from such registration requirements is available.
