CORPORATE GOVERNANCE
 
We have adopted corporate governance practices in accordance with the listing standards of the Nasdaq Global Market and commensurate with our size.
 
Our Board of Directors consists of five directors. Upon the recommendation of the Nominating and Corporate Governance Committee, the Board has determined that Messrs. Odishaw, Cardin, Doumet and Irmscher are independent within the meaning of Nasdaq rules. In making the determination that Mr. Doumet is independent, the Committee and the Board considered the fact that Mr. Doumet is the brother of Mr. George M. Doumet, who indirectly owns all of the outstanding shares of Inberdon. The fifth director is Mr. Byrne, our President and Chief Executive Officer.
 
The Board meets at least four times each year, and more frequently as required, and is responsible for supervising the management of the business and affairs of the company, including the development of our major policy and strategy. The Board has a standing Executive Committee, Nominating and Corporate Governance Committee, Audit Committee and Compensation Committee.
 
During the year ended December 31, 2007, the Board held four meetings, the Executive Committee held no meetings, the Audit Committee held seven meetings, the Compensation Committee held one meeting, and the Nominating and Corporate Governance Committee held one meeting. During the year ended December 31, 2007, each director attended at least 75% of the aggregate of (a) the total number of meetings held by the Board and (b) the total number of meetings held by all committees on which he served. The Board has a policy encouraging each director to attend our annual meeting of shareholders, and all of our directors attended the 2007 annual meeting. The Board also has a policy that, in conjunction with each regularly scheduled meeting of the Board, the independent directors will meet in executive session.
 
Governance responsibilities are undertaken by the Board as a whole, with certain specific responsibilities delegated to the four committees as described below:
 
  •  Our Executive Committee is composed of Messrs. Doumet (Chairman), Byrne and Odishaw. Within the policy and strategic direction provided by the Board, the Executive Committee may exercise all of the powers of the Board, except those required by law, regulation or Nasdaq listing standards to be exercised by the full Board, or another committee of the Board, and is required to report to the Board on all matters considered and actions taken since the last meeting of the full Board.
 
  •  Our Nominating and Corporate Governance Committee (the “Nominating Committee”) is composed of Messrs. Doumet (Chairman), Cardin, Irmscher and Odishaw, each of whom is an independent director. The primary purposes of the Nominating Committee are to identify and recommend individuals to serve as members of the Board, to recommend to the Board the duties, responsibilities, and members of each committee, and to assist the Board with other matters to ensure effective corporate governance, including making independence and other determinations related to director qualifications. The Nominating Committee is responsible for establishing the Board’s procedures for consideration of director nominees from shareholders and the Board’s process for shareholder communications with directors. The Nominating Committee will consider qualified candidates for nomination for election to the Board recommended by our directors, officers and shareholders. In considering all such candidates, the Nominating Committee will take into account the candidate’s qualifications and the size, composition and needs of the Board, in the following


5


Table of Contents

  areas of experience, judgment, expertise, and skills: our industries; accounting and finance; business judgment; management; leadership; business strategy; risk management; and corporate governance. All candidates should have a reputation for integrity, have experience in positions with a high degree of responsibility, be leaders in the companies, institutions, or professions with which they have been affiliated, and be capable of making a contribution to the company. Shareholders wishing to recommend a director candidate for consideration by the Nominating Committee should send all relevant information with respect to the individual to the chairman of the Committee in care of our Secretary. Shareholders and other interested persons who wish to contact our directors on other matters should contact our Secretary. Our Secretary, who may be contacted by mail at our corporate address or by e-mail at uslime@uslm.com, forwards communications to the director(s) as addressed in such communication. The Nominating Committee has adopted a written charter, which is available on our website located at www.uslm.com. The Nominating Committee reviews and assesses the adequacy of its charter on an annual basis.
 
  •  Our Audit Committee is composed of Messrs. Cardin (Chairman), Irmscher and Odishaw. Upon recommendation of the Nominating Committee, our Board has determined that each member of the Audit Committee is independent and meets the other qualification standards set by law, regulation and applicable Nasdaq listing standards. Based on his past education, employment experience, and professional certification in public accounting, the Board has determined that Mr. Cardin qualifies as an audit committee financial expert as defined by the Securities and Exchange Commission. The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of the work of our independent registered public accounting firm (“independent auditors”). The Audit Committee is also responsible for overseeing the administration of our Code of Business Conduct and Ethics, which is available on our website located at www.uslm.com; reviewing and approving all related-party transactions; and administering our procedures for the receipt, retention, and treatment of complaints regarding accounting, internal accounting control and auditing matters and for the confidential anonymous submission by our employees of concerns regarding questionable accounting or auditing matters, including our “whistleblower” procedures. Under our Code of Business Conduct and Ethics and our Audit Committee charter, we have written policies and procedures for the review and approval of related-party transactions. Proposed transactions with related persons and other transactions, arrangements or relationships involving a director or executive officer that may involve potential conflicts of interest are to be submitted in advance to the Audit Committee for its review and approval, with any involved director or executive officer playing no role in the investigation and consideration of the matter. In considering whether to approve any such related-party transaction, including with Inberdon or Mr. Beall or their affiliates, the Committee would consider whether the transaction was in the best interests of the company and all of its shareholders; whether the same or a similar transaction were available to the company from unrelated third parties on equal or better terms; and whether the terms of the related-party transaction were negotiated at arms’-length and were at least as favorable to the company as any other reasonably available transaction from another party. Advice from independent advisors, including formal fairness opinions, would be sought where appropriate. The Audit Committee has adopted a written charter, which is available on our website located at www.uslm.com. The Audit Committee reviews and assesses the adequacy of the charter on an annual basis. The Report of the Audit Committee is set forth below.
 
  •  Our Compensation Committee is composed of three independent directors, Messrs. Odishaw (Chairman), Doumet and Irmscher. The Compensation Committee is responsible for the evaluation, approval, and administration of salary, incentive compensation, bonuses, benefit plans, and other forms of compensation for our officers and directors. The Compensation Committee is responsible for administering the 1992 plan and the 2001 plan. The Report of the Compensation Committee is included on page 13.
 
REPORT OF THE AUDIT COMMITTEE
 
The Audit Committee is composed of three independent directors as defined under the applicable rules of the Nasdaq Global Market, Section 10A(m)(3) of the Securities Exchange Act of 1934, and the rules and regulations of the Securities and Exchange Commission (the “SEC”). The Committee oversees the company’s financial reporting process on behalf of the Board of Directors. The Audit Committee is directly responsible for the appointment,

Table of Contents

compensation and oversight of the work of the company’s independent registered public accounting firm (“independent auditors”). Management has primary responsibility for the company’s financial statements and reporting process, including the systems of internal control. Grant Thornton LLP, the company’s independent auditors, is responsible for performing an independent audit of the company’s financial statements in accordance with standards established by the Public Company Accounting Oversight Board, expressing an opinion, based on its audit, as to the conformity of such financial statements with accounting principles generally accepted in the United States of America.
 
In the performance of its oversight function, the Audit Committee has reviewed and discussed the audited financial statements with management and the independent auditors. The Audit Committee has discussed with the independent auditors the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended. In addition, the Audit Committee has received from the independent auditors the written disclosures required by the pronouncements of the Independence Standards Board and discussed with them their independence from the company and its management. The Audit Committee has considered whether the independent auditors’ provision of non-audit services to the company is compatible with the auditors’ independence.
 
The Audit Committee meets with the independent auditors, with and without management present, to discuss the results of their examinations, their evaluations of the company’s internal controls, and the overall quality of the company’s financial reporting.
 
Based on the reviews and discussions referred to above, the Audit Committee recommended, and the Board of Directors approved, the inclusion of the company’s audited financial statements in the company’s Annual Report on Form 10-K for the year ended December 31, 2007 for filing with the SEC.

EXECUTIVE COMPENSATION
 
Compensation Discussion and Analysis
 
 The Compensation Committee of our Board of Directors has the responsibility for administering our executive compensation program. The Committee reviews and, as appropriate, makes recommendations to the full Board regarding the base salaries and annual cash bonuses for executive officers, and administers our 1992 plan and 2001 plan, including the grant of stock options and shares of restricted stock. Where appropriate, we have also entered into employment agreements with certain executive officers.
 
Compensation Philosophy and Objectives.  Our principal executive compensation policy, which is endorsed by the Committee, is to provide a compensation program that will attract, motivate and retain persons of high quality and will support a long-standing internal culture of loyalty and dedication to the interests of the company and our shareholders. In administering the executive compensation program, the Committee is mindful of the following principles and guidelines, which are supported by the full Board:
 
  •  Base salaries for executive officers should be competitive.
 
  •  A sufficient portion of annual compensation should be at risk in order to align the interests of executives with those of our shareholders.
 
  •  The variable part of annual compensation should reflect both individual and corporate performance.
 
  •  As a person’s level of responsibility increases, a greater portion of total compensation should be at risk and include more stock-based compensation to provide executives long-term incentives and help to align further the interests of executives and shareholders in the enhancement of shareholder value.

Our executive officers’ compensation currently has three primary components: base salary, annual cash bonuses and stock-based awards granted pursuant to our 2001 plan. In addition, executive officers receive certain benefits that are specifically provided for in their employment agreements or are generally available to all salaried employees. We do not have any defined benefit pension plans, nonqualified deferred compensation arrangements or supplemental retirement plans for our executive officers.
 
The Committee has not engaged an outside compensation consultant, but the company does have a subscription to a compensation benchmarking tool provided by Equilar, Inc. Although the Committee does not employ benchmarking, this tool allows comparison of the compensation of our executive officers with that of other comparable size non-durable manufacturing companies.
 
For each executive officer, the Committee determines the appropriate level for each compensation component based in part, but not exclusively, on its view of competitive market factors, internal equity and consistency, and other considerations deemed relevant, such as rewarding extraordinary performance. Our Chief Executive Officer provides the Committee with recommendations for executive officers other than himself, which the Committee reviews and approves as submitted or with revisions, if any. The Committee has not adopted any formal or informal policies or guidelines for allocating compensation between long-term and currently paid compensation, between cash and non-cash compensation, or among different forms of non-cash compensation, and has not sought to formally benchmark our compensation against that of any other companies.
 
Base Salaries.  The Committee determines levels of our executive officers’ base salaries so as to be competitive with amounts paid to executives performing similar functions in comparable size non-durable manufacturing companies. The amount of each executive’s annual increase in base salary, if any, is based on a number of largely subjective factors, including changes in the individual’s duties and responsibilities, the personal performance of such executive officer, the performance of the company, cost-of-living increases, and such other factors as the Committee deems appropriate, including the individual’s overall mix between fixed and variable compensation and between cash and stock-based compensation. In the case of Messrs. Byrne, Hughes and Bowers, their base salaries cannot be below $250,000, $80,000 and $130,000, respectively, the minimums required by their respective employment agreements.
 
Salary increases for Messrs. Byrne, Hughes, Owens, Bowers and Riggs in 2007 were 5.45%, 2.92%, 3.85%, 1.94%, and 2.86%, respectively. Mr. Riggs began work with us in January 2006. Salary increases for Messrs. Byrne, Hughes, Owens, Bowers and Riggs effective in 2008 are 5.17%, 0%, 3.70%, 1.50% and 7.63%, respectively. In determining these increases, the primary factors considered were increases in the cost-of-living, the officers’ individual performances, the growth of the company and changes in their duties and responsibilities.
 
Annual Cash Bonuses.  Each of our executive officers is eligible to receive annual cash bonuses based on determinations made by the Committee. Except in the case of Mr. Byrne, we have not adopted a formal or informal annual bonus plan with preset criteria and targets. Rather, the determination to pay a cash bonus, if any, is made after the year end based on the Committee’s subjective judgment with respect to the past performance of the individual or on the individual’s attainment of nonquantified performance goals during the year. In either such case, the bonus may be based on the specific accomplishments of the individual or on the overall success of the company. In the case of Mr. Byrne, in addition to the possibility of a subjective cash bonus in the discretion of the Committee, Mr. Byrne’s employment agreement provides for an objective annual cash bonus based on our EBITDA (earnings before interest, taxes, depreciation, and amortization) compared to certain EBITDA levels set forth in Mr. Byrne’s agreement for each of 2006, 2007 and 2008, beginning at a bonus of $100,000 if EBITDA is $17,000,000 and increasing $50,000 for each $500,000 increase in EBITDA up to a maximum of the greater of $250,000 or his base salary at December 31 of the year in respect of which the EBITDA bonus is being paid if EBITDA exceeds $18,500,000.
 
Discretionary cash bonus awards are determined on an annual basis. These bonuses are paid after our earnings for the applicable year are released. Bonuses paid in 2008 for performance in 2007 are reflected on page 9 in the Summary Compensation Table. The discretionary bonuses were awarded based on the continued growth of the company, including increased production and sales, the performance of the company and each officer’s individual performance and accomplishments during 2007.

Stock-Based Awards.  The Committee also administers our 1992 plan and 2001 plan to provide stock-based incentives to our key employees, including executive officers. Grants of stock options, shares of restricted stock, and other possible stock-based compensation are based on each individual’s position within the company, level of responsibility, past performance, and expectation of future performance. In determining the number of stock-based awards to be granted to each executive officer, the Committee also considers the number of stock-based awards made in prior years to the executive officer.
 
Grants of stock-based awards to Mr. Byrne are made on the last business day of the calendar year as set forth in his employment agreement. Grants to other executive officers are made on or soon after the date that earnings for the preceding calendar year are released. The Committee also may make grants to executive officers at other times during the year in connection with new hires or promotions. The exercise price for stock options is set at the closing per share market price of our common stock on the date of grant.
 
Our stock-based compensation policies have been impacted by the implementation of SFAS 123(R). Generally, SFAS 123(R) requires all stock-based payments to employees, including grants of employee stock options and restricted stock, to be expensed based on their fair values over the vesting period. In December 2006, the Committee determined that the amount required to be expensed for stock options was significantly greater than the amount of benefit employees perceived they were receiving, especially in light of the increase in the price of our stock in recent years. Based on a review by the Committee and management of recent trends in executive compensation, the fact that stock options are comparatively more dilutive to earnings than restricted stock, as well as the effects of SFAS 123(R) noted above, the Committee decided to change the stock-based component of our executive officers’ compensation package to be weighted more heavily toward the granting of shares of restricted stock.
 
Since 2003, Mr. Byrnes’ employment agreement had provided for the grant to him of 30,000 options on the last business day of each calendar year. In December 2006, the Committee and Mr. Byrne agreed to amend his employment agreement, effective December 29, 2006, to provide for a combination of 7,500 options and 7,500 shares of restricted stock instead of the 30,000 options. The Committee determined the ratio of options and shares of restricted stock to be awarded based, in part, on the amount of estimated expense that the company would recognize if the previously required 30,000 options were granted. Options and shares of restricted stock awarded in 2007 are reflected on page 10 in the Grants of Plan-Based Awards table.
 
In February 2008, the Committee granted shares of restricted stock, and no options, to the other executive officers as follows:
 
         
    Shares of
Name
  Restricted Stock
 
M. Michael Owens
    900  
Russell W. Riggs
    1,500  
David P. Leymeister
    1,500  
 
Mr. Byrne’s options vest immediately. His shares of restricted stock vest in two semi-annual installments. The shares of restricted stock granted to the other executive officers in 2008 vest in three annual installments for Messrs. Owens and Riggs and five annual installments for Mr. Leymeister.
 
Tax Implications.  Internal Revenue Code Section 162(m) generally limits the corporate income tax deduction for compensation paid to certain named executive officers to $1 million per year, except for certain qualified and performance-based compensation. The Committee has not adopted a policy with regard to qualifying bonus awards for tax deductibility under Section 162(m) as it had no impact on the Company in previous years and only minimal impact in 2007. The Committee may consider whether to take steps to qualify its cash bonus and/or restricted stock awards in the future. Options granted under our 2001 plan are intended to constitute performance-based compensation not subject to the Section 162(m) limitation.

Employment Agreements
 
We have employment agreements with Messrs. Byrne, Hughes and Bowers. The agreements provide for a base salary to be reviewed annually. Mr. Byrne’s agreement provides him with an annual base salary of at least $250,000.


12


Table of Contents

The agreements for Messrs. Hughes and Bowers provide each of them with an annual base salary of at least $80,000 and $130,000, respectively. The agreements for Messrs. Byrne, Hughes and Bowers also provide for a discretionary bonus to be determined by the Compensation Committee. In addition to the possibility of a discretionary bonus, Mr. Byrne is eligible to receive an objective bonus based on our earnings before interest, taxes, depreciation, and amortization (EBITDA) compared to certain levels set forth in his employment agreement, as discussed above. Mr. Byrne’s agreement also provides for grants of 7,500 options and 7,500 shares of restricted stock on the last business day of each year, an annual $30,000 contribution to fund a life insurance or retirement arrangement and a country club membership. The agreements also provide for use of a company car and reimbursement of business expenses as well as participation in our 401(k) plan and other benefit programs on the same basis as our other salaried employees.
 
As set forth in the table below, in the event of a change of control of the company, Mr. Byrne is entitled to severance payments equal to two times his then-current annual base salary, benefits and bonuses if he voluntarily terminates his employment within nine months following the change of control or we terminate his employment without cause within two years following the change of control. Mr. Byrne is entitled to severance payments equal to his then-current annual base salary, benefits and bonuses for one year if he is terminated without cause other than following a change of control. Unless he provides us with three months’ notice, Mr. Byrne is not entitled to any severance payments upon his voluntary termination; if he does provide us with such notice, he is entitled to severance equal to two months’ base salary. In the case of Mr. Bowers, his severance payment would be six months’ compensation. Mr. Hughes does not have a severance arrangement. Mr. Byrne’s and Mr. Hughes’ agreements contain certain post-termination covenants not to compete.
 
Mr. Hughes’ agreement expires February 1, 2009, and Mr. Bowers’ agreement has no expiration date. Mr. Byrne’s agreement expires on December 31, 2008, and is thereafter renewable for successive one-year periods, unless the agreement is terminated earlier by him or us. Pursuant to Mr. Byrne’s agreement, we have agreed to use our best efforts to cause Mr. Byrne to remain on the Board and to be appointed a member of the Executive Committee of the Board.
 
Potential Payments Upon Termination or Change of Control
 
Regardless of the manner in which an executive officer’s employment terminates, including upon death, disability or termination for cause, he is entitled to receive amounts earned during his term of employment. Such amounts include:
 
  •  salary through the date of termination;
 
  •  stock-based compensation in which he has vested; and
 
  •  unused vacation pay.
 
In addition, Mr. Byrne may be entitled to a proportional EBITDA bonus for the year of termination if termination occurs in the second half of the year.

COMPENSATION OF DIRECTORS
 
We use a combination of cash and stock-based awards to attract and retain qualified candidates to serve on our Board. In setting director compensation, we consider the significant amount of time that our directors expend in fulfilling their duties, as well as the skill-level required by us for members of our Board.
 
The following table sets forth the annual compensation for directors who are not also employees:
 
         
Annual Retainer
  $ 15,000  
Daily Meeting Fee
  $ 1,000  
Telephonic Meeting Fee
  $ 500  
Additional Annual Retainers:
       
Audit Committee Chairman
  $ 12,000  
Compensation Committee Chairman
  $ 5,000  
 
Non-employee directors are also granted annually, at their option, either 2,000 stock options or 700 shares of restricted stock under our 2001 plan on the date of our annual meeting of shareholders. The options are granted at the closing per share market price of our common stock on the date of grant and vest immediately. The shares of restricted stock vest six months following the date of grant.
 
The following table summarizes the compensation paid to non-employee directors during 2007:

SHAREHOLDER PROPOSALS

Byrne, President and Chief Executive Officer, not later than December 3, 2008. Such Rule 14a-8 shareholder proposals must comply with SEC rules.
 
We must receive notice of other matters, including non-Rule 14a-8 proposals, that shareholders may wish to raise at the 2009 Annual Meeting of Shareholders by February 16, 2009. If we do not receive timely notice of such other matters, the persons designated as proxies for such meeting will retain general discretionary authority to vote on such matters under SEC rules.

OTHER MATTERS
 
The Board does not intend to present any other matters at the annual meeting and knows of no other matters that will be presented. However, if any other matters properly come before the meeting, the persons designated as proxies on the enclosed proxy card intend to vote thereon in accordance with their best judgment.
 
The costs of solicitation of proxies for our annual meeting will be borne by us. Solicitation may be made by mail, personal interview, telephone, and/or facsimile by our officers and regular employees who will receive no additional compensation. We may specifically engage a firm to aid in our solicitation of proxies, for which services we would anticipate paying a standard reasonable fee plus out-of-pocket expenses. We will bear the reasonable expenses incurred by banks, brokerage firms, and other custodians, nominees, and fiduciaries in forwarding proxy materials to our beneficial owners.
