(i) Organization; Power and Authority. The Company is a corporation duly organized, validly existing, and in good standing under the laws of State of Delaware. The Company has full corporate power and authority to carry on the business in which it is engaged and to own and use the properties owned and used by it.

Other than the Stockholders, there will be no other holders of Common Stock immediately after the consummation of the transactions contemplated herein.

(e) Representations and Warranties of the Stockholders. Each Stockholder hereby represents and warrants to the Company as follows:

(i) State Securities Laws. Such Stockholder intends that the laws of the State of Delaware govern the offering of the Shares to such Stockholder.

(ii) Capacity. Such Stockholder has full capacity to execute and deliver, and to perform such Stockholder’s obligations under, this Agreement.

(iii) Agreement Binding. This Agreement constitutes the valid and legally binding obligation of the Stockholder, enforceable in accordance with its terms.

(iv) Acquisition for Investment. Such Stockholder is acquiring the Shares for investment solely for the Stockholder’s account and not with a view to or for sale in connection with any distribution thereof in violation of the federal securities laws, applicable state securities laws or this Agreement.

(v) Accredited Investor. Such Stockholder (i) is an “accredited investor” within the meaning of Rule 501 promulgated under the Securities Act, (ii) has such knowledge and experience in financial and business matters that he or it is capable of evaluating the merits and risks of the purchase of the Shares, and (iii) has consulted with counsel and other advisors before committing to acquire the Shares.

(vi) Restrictions on Transfer. Such Stockholder understands that such Stockholder must bear the economic risk of the purchase of the Shares for an indefinite period of time because, except as provided in this Agreement, (A) the Company’s sale of the Shares to such Stockholder will not be registered under the Securities Act and applicable state securities laws in reliance on such Stockholder’s representations, (B) the Shares may not be sold, transferred, pledged, or otherwise disposed of without an opinion of counsel, if requested, for or satisfactory to the Company that registration under the Securities Act or any applicable state securities laws is not required, (C) except as otherwise set forth herein, the Company does not have an obligation to register a sale of the Shares (or perfect any exemption) nor has it agreed to do so in the future, and (D) the exemption provided in Rule 144 under the Securities Act is not presently available for the resale of any of the Shares and it is unlikely that such exemption will be available at any time in the future with respect to any proposed transfer of the Shares, and (E) the Company is not under any obligation to perfect any exemption for the resale of any of the Shares. Such Stockholder also acknowledges such Stockholder’s understanding that transfers of the Shares will be subject to the limitations set forth elsewhere in this Agreement.

(vii) Restrictive Legends. Such Stockholder understands that the certificate(s) evidencing the Shares will bear a restrictive legend prohibiting the transfer thereof except in compliance with (A) applicable state and federal securities laws (and may not be transferred of record except in compliance therewith), and (B) the terms of this Agreement.

(viii) Opportunity to Ask Questions. Such Stockholder has had an opportunity to ask questions and receive answers concerning the capitalization of the Company, the terms of this Agreement and the financial condition and operations of the Company, Suntron and its Subsidiaries, and has had full access to such other information concerning the Company, Suntron and its Subsidiaries as such Stockholder has requested.

(ix) Certain Risk Factors. Such Stockholder has reviewed, or has had an opportunity to review, copies of all documents entered into in connection with the Merger, including without limitation, the Certificate of Ownership and Merger pursuant to which the Merger will be accomplished and the Schedule 13e-3 describing the Merger (including exhibits and schedules thereto) and the related closing documents, and such Stockholder is familiar with the terms of the Merger. Such Stockholder also reviewed or has had an opportunity to review, (A) the Company’s Certificate of

Incorporation and Bylaws, (B) Suntron’s filings with the SEC, and (C) such other documents and information requested by such Stockholder to such Stockholder’s satisfaction. Such Stockholder understands the speculative nature of and risks involved in the proposed investment in the Company, the Merger, and all matters relating to the structure and the operations of Suntron have been discussed and explained to such Stockholder’s satisfaction.

Such Stockholder specifically acknowledges such Stockholder’s understanding that:

(A) Suntron has incurred substantial debt and the Company will incur additional debt (which will be transferred to Suntron pursuant to the Merger) to finance the Merger, and the presence of substantial amounts of debt creates significant risks, including that (1) although equity investments in highly leveraged companies such as Suntron offer the opportunity for significant capital appreciation, such investments involve the highest degree of risks and can result in the loss of such Stockholder’s entire investment, (2) other general business risks, including the effects of a recession or a downturn in the electronics industry, may have a more pronounced effect, (3) lending institutions may have rights to participate in certain decisions relating to the management of Suntron, and (4) for Suntron’s debt to be repaid and for such Stockholder’s investment in the Shares to have any value, Suntron must achieve significant growth in financial performance;

(B) such Stockholder (in the case of Stockholders other than Thayer-Blum), as a minority stockholder in the Company or, following the Merger, Suntron will have limited control over or influence in the management of Suntron;

(C) the Company is currently seeking financing to complete the Merger, such financing may or may not be on terms as favorable as Suntron’s existing debt, and if such financing is not obtained on terms acceptable to the Company, then the Merger will not be completed;

(D) Thayer-Blum will (1) receive from the Company and, following the Merger, Suntron, an annual management fee of $750,000, pursuant to a Management and Consulting Agreement, a copy of which has been made available to such Stockholder, and (2) receive certain other fees for future acquisition, disposition and/or financing transactions;

(E) the Company and, following the Merger, Suntron has incurred and will incur significant expenses in connection with the Merger and the financing thereof; and

(F) Thayer and Blum will have the power to designate the Company’s directors, and will therefore be able to control the direction and future operations of the Company.

(x) Reliance. Such Stockholder has discussed with, and relied upon the advice of, the Stockholder’s counsel with regard to the meaning and legal consequences of the Stockholder’s representations and warranties in this Agreement and the considerations involved in making an investment in the Company.

(y) Title to Contributed Shares. Such Stockholder owns the Contributed Shares set forth opposite such Stockholder’s name on Exhibit A hereto, free and clear of any liens, claims, encumbrances and restrictions of any kind whatsoever.

(f) Tax Certifications and Acknowledgments. Each Stockholder certifies under penalty of perjury that (i) the Stockholder is not subject to backup withholding either because the Stockholder has not been notified that the Stockholder is subject to backup withholding as a result of a failure to report all interest or dividends or because the Internal Revenue Service has notified the Stockholder that the Stockholder is no longer subject to backup withholding and (ii) the Stockholder is not a nonresident alien, foreign partnership, foreign trust or foreign estate.

3. Confidentiality. Except as required by applicable law (including regulations promulgated thereunder) or court order, each Stockholder (i) will maintain the confidentiality of all Company Information, and (ii) will not, directly or indirectly, use, disseminate or otherwise disclose any Company Information to any third party without the prior written consent of the Company, which may be withheld in the Company’s absolute discretion. The provisions of this Section 3 shall survive the termination of this Agreement (i) for a period of two years with respect to Confidential Information, and (ii) with respect to Trade Secrets, for so long as any such information qualifies as a Trade Secret under applicable law.

4. Execution and Delivery of a Stockholders’ Agreement.

Each of the Stockholders agrees that following the completion of the Merger, such Stockholder shall enter into a stockholders’ agreement (the “Stockholders’ Agreement”) with each other and with the other stockholders of Suntron following the Merger, which agreement shall provide for the following, among other things:

(a) Board Composition. The board of directors of Suntron shall consist of up to eleven (11) directors to be mutually agreed upon by Thayer and Blum. Notwithstanding the initial composition of the board, Thayer shall always have the right to nominate, elect and replace four (4) directors; Blum shall always have the right to nominate, elect and replace two (2) directors; the Chief Executive Officer and the Chief Financial Officer of Suntron shall be directors; and three (3) directors at any time shall be independent of Suntron, Thayer and Blum and shall be nominated jointly by Thayer and Blum.

(b) Registration Rights Agreements. Following the execution of the Stockholders’ Agreement, all existing registration rights agreements relating to Suntron shall terminate and the Stockholders’ Agreement shall provide that in the event of a future registered public offering of Suntron, Thayer shall have three (3) demand registration rights, Blum shall have two (2) demand registration rights and each Stockholder shall have customary piggyback registration rights.

(c) Other Customary Provisions. The Stockholders’ Agreement shall also provide for mutually agreeable governance provisions, transfer restrictions and other minority stockholder protections that are consistent with the following:

(i) Transfer Restrictions: The Stockholders will be subject to transfer restrictions consistent in all material respects with the terms of the First Amended and Restated Limited Liability Company Agreement of Thayer-BLUM Funding III, L.L.C., dated as of February 27, 2002 (the “LLC Agreement”), by and among Thayer Equity Investors IV, L.P. and its Affiliates, including TC Manufacturing Holdings, L.L.C. and TC KCo, L.L.C. (collectively, “Thayer”) and Blum Strategic Partners, L.P. and its Affiliates, including BLUM (K*TEC) Co-Investment Partners, L.P. (collectively, “Blum”), provided that in no event shall a Stockholder have a consent right to the transfer of Suntron shares by another Stockholder who has complied with the terms of applicable transfer restrictions provided in the Stockholders’ Agreement.

(ii) Preemptive Rights: The Stockholders will have preemptive rights with respect to any future securities issued by Suntron in order to maintain their proportionate ownership, subject to customary exceptions.

(iii) Thayer and Blum Consents. The following actions by Suntron will require the consent of both Thayer and Blum:

(A) Related party transactions, including but not limited to, any change in the management fees payable by Suntron to Thayer and Blum pursuant to the current Management and Consulting Agreement, which will remain in place;

(B) Amendment to the organizational documents of Suntron;

(D) Liquidation or dissolution of Suntron; and

(E) Change to the number of directors.

(iv) Termination. Other than with respect to the registration rights to be provided for in the Stockholders’ Agreement, the Stockholders’ Agreement shall terminate upon the closing of a future registered public offering of common stock of Suntron.

5. Dissolution; Return of Contributed Shares.
