Compensation Discussion and Analysis

     The policies of Suntron’s Compensation Committee (the “Committee”), with respect to the compensation of executive officers, including the Chief Executive Officer (“CEO”), are designed to provide compensation sufficient to attract, motivate and retain executives of outstanding ability and potential and to establish an appropriate relationship between executive compensation and the creation of stockholder value. To meet these goals, the Committee recommends executive compensation packages to our Board of Directors that are based on a mix of salary, bonus and equity awards. We believe it is important to establish a strong link between executive incentives and the creation of stockholder value. We believe that performance and equity-based compensation are the most important component of the total executive compensation package for maximizing stockholder value while, at the same time, attracting, motivating and retaining high-quality executives.

     Overall, we seek to provide total compensation packages that are competitive in terms of total potential value to our executives, and that are tailored to the unique characteristics of Suntron in order to create an executive compensation program that will adequately reward our executives for their roles in creating value for our stockholders. We intend to be competitive with other similarly situated companies in our industry.

     Benchmarking of Cash and Equity Compensation

     The Committee believes it is important when making its compensation-related decisions to be informed as to current practices of comparable companies. In 2006, the Committee reviewed compensation information for comparable public companies using survey data from third-party databases. The Committee also considered compensation analysis from Syzygy Consulting, an executive compensation consulting firm, in determining the equity awards for our CEO and Chief Financial Officer. In addition to benchmarking studies, the Committee has historically taken into account input from other sources, including input from other independent members of the Board of Directors and publicly available data relating to the compensation practices and policies of other companies within and outside of our industry. While benchmarking may not always be appropriate as a stand-alone tool for setting compensation due to the aspects of our business and objectives that may be unique to us, we generally believe that gathering this information is an important part of our compensation-related decision-making process.

     The Committee’s objective is to provide for total cash compensation near the median for comparable companies, by generally targeting performance-based cash compensation at or above the median and fixed salary compensation at or below the median. The Committee may retain the services of third-party executive compensation specialists from time to time, as the Committee sees fit, in connection with the establishment of cash and equity compensation and related policies.

     Compensation Components

     Base Salary.Generally, we believe that executive base salaries should be set near the median of the range of salaries for executives in similar positions and with similar responsibilities at comparable companies. We believe this approach minimizes competitive disadvantage while avoiding paying amounts in excess of what we believe to be necessary to motivate executives to meet corporate goals. Base salaries are generally reviewed annually, and the Committee and Board may adjust base salary amounts after taking into account individual responsibilities, performance and experience as well as competitive dynamics.

     For our executives that were employed throughout 2006, the increase in the salaries of the executive officers was 5.6% and the CEO was 33.3% compared to the annualized salaries at the end of

2005. The table below sets forth the base salaries for each of the executive officers named in the Summary Compensation Table (the “Named Executive Officers”):

     The Committee has not determined whether to adjust base salaries for the Named Executives Officers for 2007.

     Annual Executive Bonus Plan. In addition to base salaries, we believe that performance-based cash bonuses play an important role in providing incentives to our executives to achieve defined annual corporate goals. Each year, the Committee determines a target bonus for each executive. The Committee then determines certain “threshold” percentages and the corresponding bonus payout levels. The Committee works with management to develop corporate performance goals that the Committee believes management can reasonably achieve with hard work over the next year. For 2006, the Committee based the cash incentive bonus awards for each Named Executive Officer on our achieving the EBITDA target established by the Committee.

     The table below lists the potential 2006 bonus levels for each of our Named Executive Officers.

     At the end of each year, the Committee determines the level of achievement for each corporate goal and awards credit for the achievement of goals as a percentage of the goals. Actual bonuses are paid to the executives after the end of each fiscal year . Bonus payments under our annual bonus plan are contingent on continued employment with Suntron through the date that we pay out the bonus.

     In the first quarter of 2007, the Committee confirmed that the minimum EBITDA level for bonus payments was not achieved, and, accordingly, the Committee decided not to award cash bonuses to our Named Executive Officers. The Committee has not determined the performance goals and target bonus awards for 2007.

     Equity Awards. We believe that providing a significant portion of our executives’ total compensation package in stock options aligns the incentives of our executives with the interests of our stockholders and with our long-term success. The Committee and Board develop their equity award determinations based on their judgments as to whether the complete compensation packages provided to our executives, including prior equity awards, are sufficient to retain, motivate and adequately award the executives. This judgment is based in part on information provided by benchmarking studies and advice from outside executive compensation experts.

     We grant equity awards solely through our Amended and Restated 2002 Stock Option Plan (the “Plan”), which was approved by our stockholders to permit the grant of incentive and nonqualified stock options, including performance-based stock options to our officers, directors, employees and consultants. All of our employees, directors, and consultants are eligible to participate in the Plan. The material terms of the Plan are further described in Note 7 to our financial statements included in Item 8 of our 2006 Annual Report on Form 10-K, filed on April 2, 2007.

     In connection with Mr. Sabol’s employment with the Company, in February 2006 we issued options to him to purchase 100,000 shares of our common stock. In March 2006, we issued options to purchase 150,000 shares of our common stock to Mr. Singh, and 25,000 shares each to Mr. Doran and Mr. Hager. All options were granted at an exercise price equal to the fair market value of our common stock on the date of grant, and each of these options vest with respect to 25% of the shares on the first anniversary of the grant date and for an additional 12.5% of the shares every six months thereafter.

     We also granted performance-vest options to purchase an additional 150,000 shares to Mr. Singh in March 2006 and these options provided for vesting based on the same performance criteria as those contained in the 2006 Annual Bonus Plan applicable to Mr. Singh. However, since we did not achieve our EBITDA target for 2006, all of these performance-vest options expired on December 31, 2006.

     The Committee has not determined whether to grant additional equity awards to our Named Executive Officers in 2007.

     Severance Benefits. We have entered into change of control severance agreements with each of our Named Executive Officers, the terms of which are more fully described below in the section entitled “Employment Agreements and Change of Control Arrangements.” We believe these severance and change in control benefits are an essential element of our executive compensation package and assist us in recruiting and retaining talented individuals.

     Other Compensation. All of our executives are eligible to participate in our employee benefit plans, including medical, dental, life insurance and 401(k) plans. These plans are available to all salaried employees and do not discriminate in favor of executive officers. It is generally our policy to not extend significant perquisites to our executives that are not available to our employees generally. We have no current plans to make changes to levels of benefits and perquisites provided to executives.

     The following table sets forth information concerning the compensation paid by Suntron for the fiscal year ended December 31, 2006 to our Chief Executive Officer, our Chief Financial Officer, our other two executive officers, and a former executive officer who would have been among the five most highly compensated executives if he had been employed at the end of the fiscal year (these five individuals are collectively referred to as our “Named Executive Officers”).

     “All Other Compensation” in the Summary Compensation Table above includes the following components:

     (1) The amount shown in the Severance Benefits column for Mr. Kulp was paid over the six month period ended after employment was terminated on February 21, 2006.

     We granted performance-vest options for 150,000 shares to Mr. Singh in March 2006 and these options provided for vesting based on the same performance criteria as those contained in the 2006 Annual Bonus Plan applicable to Mr. Singh. None of our Named Executive Officers qualified for a payout under the 2006 Annual Bonus Plan and, accordingly, all of Mr. Singh’s performance-vest options expired on December 31, 2006. No other Named Executive Officer received an Equity or Non-equity incentive-based award in 2006.

     The following table sets forth information regarding plan-based awards to our Named Executive Officers in 2006, all of which provide that the option will expire ten years from the date of grant:

     None of our Named Executive Officers received restricted stock awards in 2006. The following table sets forth information regarding each unexercised stock option held by our Named Executive Officers as of December 31, 2006:

     The following table sets forth information with respect to Suntron’s Chief Executive Officer and the executive officers named in the Summary Compensation Table concerning options exercised in 2006:

     On May 16, 2006, we entered into an Amended and Restated Employment Agreement with Hargopal Singh, our President and Chief Executive Officer, pursuant to which his existing employment agreement was amended to (i) increase his base salary to $400,000 effective January 1, 2006; (ii) provide for a potential 2006 performance bonus of up to $480,000, based on achieving certain revenue, EBITDA and operational objectives established by the Committee; and (iii) provide for a severance payment equal to three times the sum of his base salary and the maximum bonus payable to him by Suntron for the fiscal year in which his employment is terminated, in the event that his employment is terminated within 12 months following a “Change of Control” (as defined in the agreement) by either (1) the Company without “Cause” (as defined in the agreement) or (2) Mr. Singh for “Good Reason” (as defined in the agreement).

     On February 14, 2006, we entered into a Change of Control Severance Agreement with Thomas B. Sabol in connection with his appointment as our Chief Financial Officer. On May 16, 2006, the Company also entered into Change of Control Severance Agreements with James A. Doran and Oscar A. Hager, the Company’s Chief Accounting Officer and Vice President of Information Technology and Administration, respectively (each a “Change of Control Agreement”). Each Change of Control Agreement provides that, in the event the executive is terminated within 12 months following a “Change of Control” (as defined in the Change of Control Agreement) by either (1) us without “Cause” (as defined in the Change of Control Agreement) or (2) the executive for “Good Reason” (as defined in the Change of Control Agreement), the executive will be entitled to receive as severance a payment equal to two times the sum of his base annual salary and the maximum bonus payable to him by us for the fiscal year in which the executive’s employment was terminated.

     As of the fiscal year ended December 31, 2006, our compensation committee consisted of Messrs. Forese (chairman) and Schölvinck. None of these individuals had any contractual or other relationships with us during such fiscal year except as directors and those transactions discussed under “Certain Relationships and Related Transactions”. No interlocking relationship exists between any member of our compensation committee and any member of any other company’s Board of Directors or compensation committee.

     The Committee has reviewed and discussed with management the Compensation Discussion and Analysis required by Item 402(b) of Regulation S-K, which is contained in this Annual Report on Form 10-K. Based on this review and discussion, the Compensation Committee has recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this Annual Report on Form 10-K.

     Our independent non-employee directors are entitled to an annual retainer of $15,000 which is payable on a quarterly basis. Additionally, each independent non-employee director is entitled to Board fees of $500 per meeting; $10,000 for serving on a Special Committee; $1,000 for attending audit committee meetings ($500 for telephonic meetings); $500 for attending compensation, nominating and corporate governance committee meetings ($250 for telephonic meetings). The Chairman of the audit committee receives an additional $500 for each meeting attended and $250 for each telephonic meeting.

     Upon joining our Board of Directors, each independent non-employee director receives an initial stock option award for 15,000 shares which is exercisable at the market price on the date of grant and which vests for 20% of the shares on December 31^st of each year subsequent to the grant date. At the end of each quarter thereafter, an option for 1,000 shares is granted at an exercise price equal to the closing market price on the date of grant and which vests for 20% of the shares on the first anniversary of the grant date and 20% each year thereafter. Our directors are also entitled to receive reimbursement of reasonable out-of-pocket expenses incurred by them to attend our Board and committee meetings.

     The following table sets forth a summary of the compensation we paid to our independent non-employee directors in 2006:

Thayer-Blum Management Fees

     During 2006, we incurred $750,000 for management fees to affiliates of our majority stockholder, Thayer-Blum Funding III, L.L.C. The services provided under this arrangement consist of management fees related to corporate development activities and consulting services for strategic and operational issues.

     On March 30, 2006, we entered into a $10,000,000 subordinated Note Purchase Agreement (the “Second Lien Note”) with Thayer Equity Investors IV, L.P. The Second Lien Note is collateralized by a second priority security interest in substantially all of the collateral under the US Bank credit agreement. The Second Lien Note is subordinated in right of payment to the obligations under the US Bank credit agreement and provides for a maturity date that is 45 days after the maturity date of the US Bank credit agreement. The Second Lien Note provides for an interest rate of 16.0%, payable quarterly in kind (or payable in cash with written approval from US Bank). We have the option to prepay the Second Lien Note with a redemption penalty up to 3.0% of the then outstanding principal balance. If the note is paid on the maturity date, a fee equal to 2.0% of the then outstanding principal balance is due.

     In connection with the US Bank credit agreement, Thayer Equity Investors IV, L.P. agreed to enter into a FCC maintenance agreement that requires them to make up to $5,000,000 of additional subordinated loans to us if our fixed charge coverage ratio, or FCC, falls below a prescribed level. Loans pursuant to the FCC maintenance agreement would have similar terms as the Second Lien Note; however, the interest rate on such additional loans can not exceed 18.0%.

     KPMG LLP served as our independent registered public accounting firm for each of the years in the three-year period ended December 31, 2006.

     The following is a summary of fees, all of which were approved by our audit committee, billed by KPMG LLP for audit and other professional services during the years ended December 31, 2005 and 2006:

     “Audit-related fees” include fees related to the statutory audit of our Mexican subsidiary. “Income tax fees” include tax return preparation and consultation on various tax-related issues.

     In 2003 our Audit Committee adopted a formal policy concerning pre-approval of audit and non-audit services to be provided by our independent auditors. The policy requires that all proposed services to be provided by KPMG LLP must be pre-approved by the audit committee before any services are performed. This policy includes all audit, tax and consulting services that KPMG LLP may provide to the Company. In evaluating whether to engage KPMG LLP for non-audit services, our Audit Committee considers whether the performance of services other than audit services is compatible with maintaining the independence of KPMG LLP.
