Stockholder nominees:The policy of the Nominating & Governance Committee is to consider properly-submitted stockholder nominations for candidates for membership on the Board as described below under “Identifying and Evaluating Nominees for Directors.” In evaluating such nominations, the Nominating & Governance Committee seeks to achieve a balance of knowledge, experience and diversity on the Board. Any stockholder nominations proposed for consideration by the Nominating & Governance Committee should include the nominee’s name and qualifications for Board membership and should be addressed to:

In addition, our bylaws permit stockholders to nominate directors for consideration at an annual stockholders meeting. For a description of the process for nominating directors in accordance with our bylaws, see “Questions and Answers- What is the deadline to propose actions for consideration at next year’s annual meeting of stockholders or to nominate individuals to serve as directors?” on page 3.

Director Qualifications:Our Corporate Governance Guidelines contain Board membership criteria that apply to Nominating & Governance Committee-recommended nominees for a position on the company’s Board. Under these criteria, members of the Board should meet the Board’s qualifications as independent (as applicable) and should have sufficient time to carry out their duties and to provide insight and practical wisdom based on experience. Their service on other boards of public companies should be limited to a number that permits them, given their individual circumstances, to perform responsibly all director duties. Each director must represent the interests of the company and its stockholders.

Identifying and Evaluating Nominees for Directors:The Nominating & Governance Committee uses a variety of methods for identifying and evaluating nominees for director. The Nominating & Governance Committee regularly assesses the appropriate size of the Board, and whether any vacancies on the Board are expected due to retirement or otherwise. In the event that vacancies are anticipated or otherwise arise, the Nominating & Governance Committee considers various potential candidates for director. Candidates may come to the attention of the Nominating & Governance Committee through current Board members, professional search firms, stockholders or other persons. These candidates are evaluated at regular or special meetings of the Nominating & Governance Committee and may be considered at any point during the year. As described above, the Nominating & Governance Committee considers properly-submitted stockholder nominations for candidates for the Board. Following verification of the stockholder status of persons proposing candidates, recommendations are considered by the Nominating & Governance Committee. If any materials are provided by a stockholder in connection with the nomination of a director candidate, such materials are forwarded to the Nominating & Governance Committee. The Nominating & Governance Committee also reviews materials provided by professional search firms or other parties in connection with a nominee who is not proposed by a stockholder.

Executive sessions of non-management directors are held periodically during the year. The sessions are scheduled and chaired by Mr. J. Michael Adcock who was elected by the Board to chair each executive session. Meetings are also held from time to time with the Chairman and the Chief Executive Officer for a general discussion of relevant subjects. Any non-management director can request that an executive session be scheduled.

Individuals may communicate with the Board by submitting an e-mail to the company’s Board in care of the company’s Corporate Secretary at mark.schell@unitcorp.com or sending a letter to: Board of Directors, c/o Corporate Secretary, Unit Corporation, 7130 S. Lewis, Suite 1000, Tulsa, Oklahoma 74136.

The chair of the Nominating & Governance Committee has been designated as the person to receive communications directed to non-management directors. Our stockholders may write to the Chairman of this or any other Board committee or to the outside directors as a group c/o Mark E. Schell, Senior Vice President and General Counsel, Unit Corporation, 7130 South Lewis, Suite 1000, Tulsa, Oklahoma 74136.

Stockholder communications are distributed to the Board, or to the appropriate individual director or directors, depending on the facts and circumstances of the communication. However, at the request of the Board, certain items that are not related to the duty and responsibilities of the Board be excluded, such as: advertisements, junk mail, mass mailings, spam and surveys.

Each year the Board evaluates its performance and effectiveness. Each director completes a Board evaluation form developed by the Nominating & Governance Committee to solicit feedback on specific aspects of the Board’s role, organization and meetings. The collective ratings and comments are then compiled by the Chairman of the Nominating & Governance

Committee and presented by him to the full Board. Additionally, each Board committee conducts an annual self-evaluation of its performance through a Committee evaluation form.

Mr. Cromling was elected to his position as Executive Vice President, Drilling of Unit Drilling Company on April 1, 2005.

The table below shows the outstanding unvested restricted stock awards to the named executive officers at December 31, 2005.

Because elements of the Summary Compensation Table may not lend themselves to being totaled due to different presentation requirements, to provide additional transparency on the total compensation for our named executive officers, we are providing the following Present Value of Total Compensation table. The components of executive compensation included in this table are as follows:

Cash compensation, consisting of salary and annual incentive compensation (bonus);

Long-term incentive compensation, consisting of stock options and restricted stock awards; and

Other compensation, including 401(k) plan matching payments, active employee benefits and the ~~year earned. (2)~~ value of perquisites.

The ~~amount listed under~~following table shows a summary of the ~~Other Annual Compensation column represents the dollar value associated with the use of a company vehicle~~stock options exercised by the named executive ~~officer. (3) "All Other Compensation" represents Unit's matching contributions to Unit's 401(k) thrift plan for~~officers in 2005, as well as the ~~named executive officer. 8~~ Stock Options There were no stock options granted in 1999 to the Chief Executive Officer or to any of the other four most highly compensated executive officers.

Certain of the named executive officers were awarded stock options in 2005. The table below shows all the common stock options granted to each of the named executive officers in 2005 and the potential value of such grants at stock appreciation rates of 0%, 5% and 10% compounded annually over the maximum ten-year term of the options, as well as the value of the grant on the ~~basis~~award date.

The company also provides other benefits such as medical, dental and life insurance and disability coverage to each named executive officer through our various benefit plans, which are also provided to most other eligible company employees.

Active employee benefits such as medical, dental, life insurance and disability coverage are available to most full time company employees, including the named executive officers, through our active employee benefits plans. The value of these benefits is not required to be included in the Summary Compensation Table since they are made available on a company-wide basis.

The company also provides vacation and other paid holidays to most of its full time corporate employees, including the named executive officers, which, we believe, are comparable to those provided at other similar size companies.

Generally the terms of the ~~difference between $7.50~~stock options granted under this plan are as follows:

Options vest in annual 20% installments starting one year from date of grant;

Options are awarded at the fair market value of our common stock on date of grant;

Options can be either qualified or nonqualified; and

Outstanding options are subject to vest in the ~~option exercise price multiplied~~event of a change-in-control as defined in the plan.

This plan, which is administered by the ~~number~~Compensation Committee, was approved by our stockholders. Our non-employee Directors are not eligible to participate in this Plan.

Under the this plan our employees may be awarded bonuses either in cash or stock (including restricted stock awards) or a combination of both. Awards may be payable in a lump sum or in annual installments subject to certain restrictions.

This plan is administered by our Compensation Committee. Our non-employee Directors are not eligible to participate in this Plan.

Under the Unit Corporation Employee Thrift Plan, which is tax-qualified retirement savings plan, participating employees may contribute up to 99 percent of compensation on a before-tax basis into their plan accounts. Total contributions may not exceed IRS determined maximums for any given year. In addition, under the plan, we can make a matching contribution. The amount of our matching contributions is generally determined by our Compensation Committee each year and is generally made in shares of our common ~~stock underlying~~stock. For the ~~options.~~ 2006 Plan Year, the Compensation Committee has approved a match of 117% of the first 6% of salary contributed by participants.

We have funded a trust to secure the obligations to make payments under this plan.

We have also established a salary deferral plan which allows certain participants to defer the recognition of salary for income tax purposes until actual distribution of benefits which occurs at either termination of employment, death or certain defined unforeseeable emergency hardships. This is a non-qualified plan.

We indemnify our directors and some of our elected officers to the fullest extent permitted by law so that they will be free from undue concern about personal liability in connection with their service to the company. This is required under our bylaws, and we have also entered into agreements with certain of those individuals contractually obligating us to provide this indemnification to them.

The following table summarizes information, as of December 31, 2005, relating to our equity compensation plans.

TERMINATION OF EMPLOYMENT AND ~~CHANGE IN CONTROL~~CHANGE-IN-CONTROL ARRANGEMENTS ~~- -------------------------------------------------------------------------------~~

As allowed for in our stock option plan, each option agreement contains a provision vesting all stock options in the event of a ~~"change-in-control"~~“change-in-control” of ~~us.~~the company. A ~~"change-in-control"~~“change-in-control” is deemed to have occurred at such time as any person or group, other than ~~Unit~~the company or an ~~Exempt Person,~~“Exempt Person”, is or ~~become s~~becomes the beneficial owner, directly or indirectly, of our securities representing 50% or more of 9 the combined voting power of our then outstanding securities. An Exempt Person is generally defined to be any person (or estate or trust of such person) who, , on the date of the plan, owned securities representing more than 20% of the combined voting power of our then outstanding securities, and any spouse, parent or issue of such person.

On December 20, 1996, effective as of January 1, 1997, the ~~board~~Board adopted the Separation Benefit Plan of Unit Corporation and Participating ~~Subsidiaries (the "Plan").~~Subsidiaries. The ~~Plan~~plan is generally applicable to all of our ~~full time~~full-time salaried employees and to the salaried employees of our ~~two principal~~ subsidiaries, ~~excluding any employees who are also our directors,~~ who have been with their employer for at least one year. Subject to the terms of the ~~Plan,~~plan, any eligible employee whose employment is terminated is ~~en titled~~entitled to receive a separation benefit in an amount calculated by dividing the eligible ~~employee's~~employee’s average annual base salary

in effect immediately ~~prior to such employee's~~before the employee’s separation by 52 to determine a weekly separation benefit amount. The number of weekly separation benefit payments then payable to an eligible employee is calculated based on the ~~employee's~~employee’s years of service in accordance with a schedule set forth in the ~~Plan.~~plan. Employees who voluntarily leave their employment are not entitled ~~t o~~to receive a separation benefit unless they have completed at least 20 years of service. Any eligible employee who has completed 20 years of service or more is vested in his or her separation benefit, subject to fulfilling the other requirements of the ~~Plan.~~plan. Separation benefit payments are limited to a maximum of 104 weekly payments. The ~~Plan~~plan also provides that, unless otherwise provided by our ~~board~~Board before a “change-in-control” of ~~directors prior to a "change-in-control" of us,~~the company, as defined in the ~~Plan,~~plan, all eligible employees shall be vested in their separation benefit as of the date of ~~such "change-in-control"~~the “change-in-control” based on their years of service. As a condition to receiving the separation benefits, employees must sign a separation agreement waiving any claims the employee ~~m ay~~may have against ~~our subsidiaries~~the company or ~~us.~~ its subsidiaries.

The following table identifies the amounts that would be due each of the officers identified in the Summary Compensation Table assuming that those amounts were determined as of December 31, 2005.

On October 28, 1997, the ~~board~~Board adopted the Separation Benefit Plan for Senior Management. This plan is similar in terms to the benefits and requirements described above for the Separation Benefit Plan, with the exception that the ~~compensation committee~~Compensation Committee determines who will participate in this plan. In addition, the ~~committee~~Committee is given the authority to increase (up to a maximum of 104) the number of weekly separation benefit payments a participant would otherwise be entitled to receive under the ~~pl an~~plan if the participant is involuntarily terminated. ~~Currently, only Messrs. Kirchner,~~

Effective with their retirement from the company, Mr. Keeley, Mr. Lamborn and Mr. Nikkel are receiving payments under these plans. Their compensation is paid out over a period not to exceed 26 months. Currently there are no other participants in this Plan.

The following table identifies the amounts due to certain of our retired former executive officers under the Senior Management Separation Benefit Plan and the amount paid to each as of December 31, 2005:

This plan is identical to the Separation Benefit Plan with the exception that a participant will vest in his or her earned benefit on the earliest of the participant reaching the age of 65 or serving 20 years with us. As of December 31, 2005, there were no participants in this plan, however in January 2006, the Compensation Committee elected to allow 33 employees to participate in the plan. Participation in this plan is in lieu of participation in any of the other Separation Benefit Plans.

We have entered into key employee change-in-control contracts with Messrs. Pinkston, Schell, Merrill and Belitz. Mr. Belitz is our Controller. These severance contracts have an initial three-year term that is automatically extended for one year upon each anniversary, unless a notice not to extend is given by us. If a change-in-control of the company (as defined below) occurs during the term of the severance contract, then the contract becomes operative for a fixed three-year period. The severance contracts generally provide that the executive’s terms and conditions of employment (including position, work location, compensation and benefits) will not be adversely changed during the three-year period after a change-in-control. If the executive’s employment is terminated by the company (other than for cause, death or disability), the executive terminates for good reason during such three-year period, or the executive terminates employment for any reason during the 30-day period following the first anniversary of the change-in-control, and on certain terminations before a change-in-control or in connection with or in anticipation of a change-in-control, the executive is generally entitled to receive the following payment and benefits:

earned but unpaid compensation;

up to 2.9 times the executive’s base salary plus annual bonus (based on historic annual bonus); and

the company matching contributions that would have been made had the executive continued to participate in the company’s 401(k) plan for up to an additional three years.

In addition, the severance contract provides for a continuation of various medical, dental, disability and life insurance plans and financial counseling for a period of up to three years, outplacement services and the payment of all legal fees and expenses incurred by the executive in enforcing any right or benefit provided by the severance contract. The severance contract provides that the executive is entitled to receive a payment in an amount sufficient to make the executive whole for any excise tax on excess parachute payments imposed under Section 4999 of the Code. As a condition to receipt of these severance benefits, the executive must remain in the employ of the company and render services commensurate with his position. The executive must also agree to retain in confidence any and all confidential information known to him concerning the company and its business so long as the information is not otherwise publicly disclosed. As of the date of this proxy statement, no amounts have been paid under the severance contracts.

For purposes of the severance contracts, a change-in-control is generally defined as:

(1) Any individual, entity or group acquiring beneficial ownership of 15% or more of either the outstanding shares of the company’s common stock or the combined voting power of the outstanding voting securities of the company entitled to vote generally for the election of directors;

(2) Individuals who constitute the Board on the date thereof cease to constitute a majority of the Board, provided that an individual whose election or nomination as a director is approved by a vote of at least a majority of the directors as of the date thereof will be deemed a member of the incumbent Board;

(3) Approval by the company’s stockholders of a reorganization, merger or consolidation or sale or other disposition of all or substantially all of the assets of the company or the acquisition of assets of another entity, unless following the business combination:

all or substantially all of the beneficial owners of the company’s outstanding common stock prior to the business combination own more than 60% of the outstanding common stock of the corporation resulting from the business combination;

no person, entity or group owns 15% or more of the outstanding voting securities of the corporation resulting from the business combination; and,

at least a majority of the Board of the company resulting from the business combination were members of the company’s Board prior to the business combination; or

(4) Approval by the company’s stockholders of a complete liquidation or dissolution of the company.

Under the individual severance agreements with the named executive officers that address their termination of employment following a change-in-control of the company, each executive would be entitled to receive the following estimated benefits. These disclosed amounts are estimates only and do not necessarily reflect the actual amounts that would be paid to the executive, which would only be known at the time that they become eligible for payment and would only be payable if a change-in-control were to occur. The table reflects the amount that could be payable under the various arrangements assuming that the change-in-control occurred at December 31, 2005, including a gross-up for certain taxes in the event that any payments made in connection with a change-in-control would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code.

in which termination occurs. These amounts are based on the 2005 salary and declared bonus for 2005. This amount also includes the amounts shown as earned under the Separation Benefit Plan on page 22 and amounts for previously declared but unpaid bonus installments.

In connection with the retirement of Mr. King Kirchner from his position as Chief Executive Officer of the company, we entered into a Separation Agreement with Mr. Kirchner on May 11, 2001. Under this agreement, Mr. Kirchner is entitled to receive a total of $2.4 million. For the first two years under the agreement, Mr. Kirchner received, as part of the total due him, payments under the terms of the company’s Separation Benefit Plan for Senior Management or a total of $560,000. Then, commencing in July 2003 (and continuing through June 2009), Mr. Kirchner is receiving the $1,840,000 balance at the rate of $300,000 per year paid in monthly installments of $25,000. As of December 31, 2005, Mr. Kirchner had received monthly payments totaling $770,000.

We have also entered into an agreement with Mr. John Nikkel, our former Chief Executive Officer, providing for him to serve as a consultant to the company when he retired on April 1, 2005. Under this agreement, for the term of the agreement which is for a one year term extendable for successive one year periods by mutual agreement, Mr. Nikkel receives, on an annual basis, $70,000 per year. In addition, we provided him with office space and secretarial services for the time he serves as a consultant. In addition, at its February 2005 meeting, the Compensation Committee elected to reward Mr. Nikkel for his 21 years of service to the company by awarding him with a cash bonus of $750,000 payable in 24 monthly installments commencing on the 20th month following his retirement on April 1, 2005.

The ~~members~~committee may also, as it did in the case of the Unit Corporation Stock and Incentive Compensation Plan, approve and recommend for submission to our stockholders any new equity compensation plans.

The determinations of the committee at its December meeting are, in the case of salaries and bonuses, generally implemented as of January 1 of the year following the meeting. Any stock awards have, until the committee’s December 2005 meeting, only been made in the form of stock options and are effective as of the date of the committee’s decision to award the options.

The committee feels that by waiting until December of each year to make its decisions regarding the compensation levels of the executive officers for the following year, it has the benefit of being able to take into account the full annual performance of the company, both financially and operationally.

If, during the year, circumstances warrant that the committee make adjustments to its previously approved compensation decisions, the committee will evaluate those needs at one or more meetings scheduled throughout the year. Until recently, such decisions generally related to the compensation to be paid to newly hired executive officers. However, because of the recent industry growth in all segments of the company’s operations, the company has been faced with increasing compensation pressure from industry competitors. This pressure has, especially during 2005, forced the company and the committee to make certain adjustments during the course of the year to its compensation program for specific individuals, including that related to Mr. John ~~S. Zink, Don Cook, J. Michael Adcock~~Cromling and ~~John H. Williams.~~ Mr. Brad Guidry, as more fully discussed below.

The objectives of the committee in determining executive compensation are to to:

retain ~~and reward~~ qualified individuals serving as our executive ~~officers. To achieve these objectives,~~officers,

reward the company’s employees for past performance, and

motivate the executive officers to further the company’s growth and success.

Each year the committee ~~relies primarily on salary, annual bonuses (awardable either in stock or cash) and awards under our stock option plan. In making its decisions,~~reviews the ~~committee takes into account~~ executive officers’ compensation with regard to:

the conditions within our industry

our income, ~~and~~ cash flow, and asset base growth,

the attainment of any designated business ~~objectives.~~ objectives, and

its relationship with that being offered by other companies.

Individual performances are also reviewed, taking into account the ~~individual's~~individual’s responsibilities, experience and potential and his or her period of service ~~and current salary and~~with the ~~individual's compensation level as compared to similar positions at other companies.~~ company.

The ~~committee's~~committee’s evaluation of these considerations is, for the most part, subjective and, to date, it has not established any specific written compensation plans or formulas ~~pursuant to~~under which the executive ~~officers'~~officers’ annual compensation is ~~deter mined. Base Salary We do~~determined.

The committee has not historically used outside consultants to assist the committee with regard to its executive compensation policies and decisions. The committee does, however, use each year the Mercer Energy Compensation Survey published by Mercer Human Resource Compensation, Inc. as a guide to informing the committee of the compensation programs of many of the company’s competitors.

The company’s executive compensation program (as well as its overall program) has historically consisted of the following elements:

annual bonuses (awardable either in stock or cash), and

awards under our stock option plan.

The company does not currently have an employment ~~agreement~~agreements with any of ~~our~~its executive officers.

Base Salary. In determining the base salaries for the executive officers for ~~1999~~2005, the committee relied primarily on its evaluation of the compensation being paid to individuals holding comparable positions in ~~the~~our industry. In doing so, the committee relied ~~to a large extent,~~ on the results of the ~~KPMG Peat Marwick LLP 1998~~Mercer Energy Compensation Survey, which surveyed the compensation and benefit programs of ~~140~~a number of oil and ~~gas, related~~gas-related companies, one of which was ~~us.~~the company. It was the ~~committee's~~committee’s objective to set the ~~executives'~~executives’ base salary at approximately the ~~competitive mid-range~~75% range reflected in the survey. Within this range, the committee then made any adjustments based on individual performance evaluations. Taking these factors into consideration, the committee decided ~~not~~ to recommend to the full Board that it increase the ~~1999~~2004 salaries of the ~~named executive officers.~~ following officers by the percentages indicated: Larry D. Pinkston 16%, Mark E. Schell 8.5% and David T. Merrill 9.7%.

As noted elsewhere in this proxy statement, Mr. Cromling and Mr. Guidry were promoted to their current positions with two of our subsidiaries on April 1, 2005 and March 1, 2005, respectively. At those times, the committee approved, based on the recommendations of the company’s management, that Mr. Guidry’s salary be increased from $152,500 to $170,000 and Mr. Cromling’s salary be increased from $162,000 to $180,000. These increases were based on the added responsibilities assumed by these individuals as well as a desire to keep the company’s compensation for them at a competitive level.

Bonuses. Executive officers are eligible to earn annual bonuses either in cash or in stock. Stock bonuses are awarded ~~pursuant to~~under the ~~bonus plan~~Employee Bonus Plan approved by our stockholders on May 1, 1985 and, as amended, on May 3, 1995. The amount and type of any bonuses awarded to the executive officers is determined solely at the subjective discretion of the committee. The committee does not base its decisions on predetermined formulas, choosing instead to rely on its evaluation of the various considerations set forth above. In addition, when appropriate, bonuses are awarded to recognize short-term individual performance.

Generally the bonuses awarded to the company’s executive officers are structured to be paid in three annual installments, with the first payment to be made in the first month of the year following the committee’s decision to award the bonuses. The next two installments are made in January of the next two succeeding years. Receipt of the remaining installments is contingent on the recipient’s continued employment with the company.

Bonus awards to the executive officers for the 2005 year were: Mr. Pinkston, $180,000; Mr. Schell, $100,000; Mr. Merrill, $40,000; Mr. Cromling, $50,000; and Mr. Guidry, $60,000. Consistent with the committee’s previous bonus awards, the first installment of these bonuses was paid as part of the total bonus amount paid to each executive officer in January, 2005.

Stock Options. Stock options are granted under the stock option plan approved by our stockholders on May 2, 1984 and, as amended, on May 3, 1989 and May 3, 1995. The committee believes that stock options provide an incentive for the executive officers to maximize long-term stockholder value. ~~Historically, although not required, stock~~Stock option grants are made at 100% of the market price on the date of grant. ~~Options~~Generally, options become exercisable in annual 20% increments after one year and have a ten-year life. The number of options that are granted to an executive officer is based on the ~~individual's~~individual’s performance and level of responsibility. Option awards will vary in size based on position level (more senior managers receive a higher multiple). Stock options are granted to the executive officers at the discretion of the committee. The ~~committee's~~committee’s decisions with respect to awarding stock options are generally made 11 late each year thus allowing the committee to evaluate our annual results as part of its ~~decision making~~decision-making process. No

In 2005, no stock options were granted to Mr. Pinkston, Schell or Merrill. However, as part of the compensation awarded to Mr. Cromling and Guidry on their promotions in 2005, the committee authorized the award of a stock option to each of these individuals covering 7,500 shares of common stock.

From January 1, 2005 until his retirement effective April 1, 2005, Mr. John Nikkel served as the company’s Chief Executive Officer. In view of his pending retirement, the committee elected not to adjust Mr. Nikkel’s salary or award him a bonus at its December 2004 meeting. However, at its February 2005 meeting, the committee did elect to reward Mr. Nikkel for his 21 years of service by awarding him a cash bonus of $750,000 payable in 24 monthly installments commencing on the 20th month following his retirement.

Effective with Mr. Nikkel’s retirement, Mr. Pinkston was elected to the position of the company’s Chief Executive Officer. Mr. Pinkston’s compensation for 2005 was not adjusted from that previously discussed as a result of his election to the position as Chief Executive Officer.

On December 13, 2005, the committee approved and the Board ratified (and approved, where required), the following compensation for the company’s executive officers for 2006:

The cash bonuses represented above are payable in ~~1999. Chief Executive Officer Mr. Kirchner's salary~~three annual installments, commencing in January 2006. The first installment in the amount of 50% of the award was paid in January 2006 and the balance will be paid in two equal annual installments. Receipt of these amounts is contingent on the employee remaining in the employment of the company.

The restricted stock awards were issued under the company’s Employee Bonus Plan and evidenced by a restricted stock bonus ~~are determined by~~agreement entered into between each of the above employees and the company. Each agreement, in addition to certain other provisions, provides that one-half of the Restricted Shares vests on January 1, 2007 and the other one-half vests on January 1, 2008, subject in each case to the employee remaining in the employment of the company. In the event of a “change in control” of the company (as defined in the agreement), any unvested shares will immediately vest in the recipient. This is the first time the committee ~~substantially~~has used restricted stock awards as part of its compensation program. The committee chose to use restricted stock awards in ~~accordance~~lieu of stock options as a means of more closely linking the executive’s compensation to that of the company’s stock price.

At this meeting the committee also decided to proceed with the ~~policies described above relating~~preparation of a new incentive plan to ~~all executive officers. Based on~~replace the company’s existing Employee Bonus Plan and its ~~review,~~employee Stock Option Plan. The committee thought that the company needed to update its equity plans in view of recent tax and accounting changes as well as desiring to have a plan that would allow the committee ~~choose not~~a greater range of options in structuring its equity based compensation. The result of this effort is the Unit Corporation Stock and Incentive Compensation Plan that is being submitted for approval to ~~raise Mr. Kirchner's 1999 salary. 1993 OBRA - Executive~~the company’s stockholders with this proxy statement. The committee views the adoption and approval of this plan as an important step in the ability of the company to maintain a competitive compensation program.

Deductibility of Compensation ~~Tax Deductibility Beginning in 1995,~~Under Internal Revenue Code Section 162 (m)

Section 162(m) of the Internal Revenue Code, ~~Section 162(m), limits our ability to deduct, for federal income tax purposes, certain non-performance based compensation~~adopted in ~~excess of~~1993, imposes a $1 million ~~per year paid~~cap, subject to ~~individual officers named in the Summary Compensation Table. Based~~certain exceptions, on the ~~amount~~deductibility to the company of compensation paid to ~~each~~the executive officers named in our proxy statement. Currently, the compensation paid under our stock option plan is not deductible. Cash compensation voluntarily deferred by the executive officers under the deferred compensation plan is not subject to the Section 162(m) cap until the year paid. After reviewing the compensation to be paid in 2005 that was subject to the Section 162(m) cap, the committee did not expect that compensation to exceed $1 million for any of the named ~~officers in fiscal 1999, it does~~executive officers. Therefore, the committee believes that the company will not ~~appear that~~be subject to any Section 162(m) ~~will have a significant impact~~limitations on usthe deductibility of compensation paid to the company’s named executive officers for fiscal year 2005.

The committee continues to consider other steps which might be in the ~~near term. However,~~company’s best interests to comply with Section 162(m), while reserving the right to award future compensation which would not comply with the Section 162(m) requirements for nondeductibility if the committee ~~will continue to monitor whether its executive compensation plans should be amended to meet~~concluded that this was in the ~~deductibility requirements of the tax law.~~ company’s best interests.

Members of the Compensation Committee: ~~John S. Zink Don Cook John H. Williams~~

The following report of the Audit Committee shall not be incorporated by reference into any of our prior filings under the Securities Act of 1933 or the Securities Exchange Act of 1934 that incorporated future filings or portions thereof, except to the extent that we specifically incorporate this information by reference.

The SEC rules now require that we include in our proxy statement a report from the Audit Committee of the Board. The following report concerns the committee’s activities regarding oversight of our financial reporting and auditing process.

In accordance with its written charter, the Audit Committee of the Board assists the Board in fulfilling its responsibility for oversight of the quality and integrity of our accounting, auditing and financial reporting practices. During the year 2005, the committee met five times. The committee chair, as representative of the committee, discussed the interim financial information contained in each quarterly earnings announcement and Form 10-Q with the company’s Chief Financial Officer and independent registered public accounting firm before public release.

The Board and the Audit Committee believe that the Audit Committee’s current member composition satisfies the rule of the NYSE that governs audit committee composition, including the requirement that audit committee members all be “independent directors” as that term is defined by applicable NYSE rule.

The company’s management has the primary responsibility for the financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the committee reviewed the audited financial statements in the Annual Report with management including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The committee reviewed with the company’s independent registered public accounting firm, who are responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of the company’s accounting principles and such other matters as are required to be discussed with the committee under generally-accepted auditing standards, including Statement on Auditing Standards No. 61. The committee has discussed with the independent registered public accounting firm the auditors’ independence from management, including the implications of the SEC regulations regarding the provisions of non-audit services by the independent registered public accounting firm and determined that the provisions of the non-audit services were not inconsistent with the independent registered public accounting firm’s status as independent registered public accounting firm. In addition, the committee received the written disclosures and letter from the independent registered public accounting firm required by the Independence Standards Board, Standard No. 1.

The committee also reviewed the report of management contained in the company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2005 filed with the SEC, as well as PricewaterhouseCoopers LLP’s Report of Independent Registered Public Accounting Firm (included in the company’s Annual Report on Form 10-K). This report related to its audit of (i) the consolidated financial statements, (ii) management’s assessment of the effectiveness of internal control over financial reporting and (iii) the effectiveness of internal control over financial reporting. The committee continues to oversee the company’s efforts related to its internal control over financial reporting and management’s preparations for the evaluation in fiscal 2006.

Based on review and discussions with management and the independent registered public accounting firm, the committee recommended to the Board that the company’s audited financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2005, for filing with the SEC.

Each member of our Audit Committee is financially literate, knowledgeable and qualified to review financial statements. The Board has

determined that Don Cook qualifies as an “audit committee financial expert” under the rules of the SEC.

The Audit Committee has appointed PricewaterhouseCoopers LLP as the company’s independent registered public accounting firm for the fiscal year ending December 31, 2006.

The following table shows the fees for professional audit services provided by PricewaterhouseCoopers LLP for the integrated audit of the company’s annual financial statements for the years ended December 31, 2005 and 2004, and fees billed for other services during those periods.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Auditor

Consistent with SEC policies regarding auditor independence, the Audit Committee has responsibility for appointing, setting compensation and overseeing the work of the independent registered public accounting firm. In recognition of this responsibility, the Audit Committee has established a policy to pre-approve all audit and permissible non-audit services provided by the independent registered public accounting firm.

Before incurring the following, management will submit a list of services and related fees expected to be rendered during that year within each of the following four categories of services to the Audit Committee for approval:

letters, statutory audits, and discussions surrounding the proper application of financial accounting and/or reporting standards.

The Audit Committee pre-approves the independent registered public accounting firms services within each category. The fees are budgeted and the Audit Committee requires the independent registered public accounting firm and management to report actual fees versus the budget periodically throughout the year. During the year, circumstances may arise when it may become necessary to engage the independent registered public accounting firm for additional services not contemplated in the original pre-approval categories. In those instances, the Audit Committee requires specific pre-approval before engaging the independent registered public accounting firm.

The Audit Committee may (and has at various times in the past) delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the Audit Committee at its next scheduled meeting.

Item 1 is the election of three directors to the Board. Our Amended and Restated Certificate of Incorporation provides that the number of directors the company may have may not be less than three nor more than ten. Our Board currently is composed of nine members and is divided into three classes with each director serving for a three-year term. At each annual meeting, the term of one class expires. The term of service for those directors serving in Class I expires at this meeting.

We know of no reason why any nominee may be unable to serve as a director. If any nominee is unable to serve, your proxy may vote for another nominee proposed by the Board, or the Board may reduce the number of directors to be elected.

If any director resigns, dies or is otherwise unable to serve out his or her term, or the Board increases the number of directors, the Board may fill the vacancy or elect the new director.

Mr. Sullivan and Mr. Christopher are standing for their first election by our stockholders. Both were elected to our Board effective July 1, 2005 at the recommendation of the Nominating and Governance Committee and on the unanimous

vote of the Board. One of our non-management directors initially recommended Mr. Sullivan for consideration as a Board member while Mr. Christopher was considered on the initial recommendation of the Chairman of the Board of Directors.

Our Nominating & Governance Committee has recommended, and the Board has approved, the nominees listed below to stand for election. Information concerning each nominee and each continuing director is provided below.

ITEM 2: ~~RATIFICATION OF APPOINTMENT OF AUDITORS - ------------------------------------------------------------------------------- The board~~Ratification of Appointment of Independent Registered Public Accounting Firm

Our Audit Committee has unanimously selected PricewaterhouseCoopers LLP as our independent ~~auditors~~registered public accounting firm for our ~~2000~~2006 fiscal year. ~~The board is~~We are asking you to ratify and approve this action. A representative of PricewaterhouseCoopers LLP, ~~who~~ will attend the annual meeting, will have the opportunity to make a statement if he or she desires to do so and will be available to answer appropriate questions.

Although the law does not require such ratification, the ~~board~~Audit Committee believes that you should be given the opportunity to express your views on this matter. However, even if you ratify the selection, the ~~board~~Audit Committee may still appoint a new independent ~~auditors~~registered public accounting firm at any time if it believes that such change would be in the best interest of the company and its stockholders. Failure to ratify ~~such~~this selection is not binding on the ~~board .~~ Audit Committee. However, if our stockholders do not ratify this selection, the Audit Committee will reconsider the appointment.

THE BOARD ~~OF DIRECTORS~~ UNANIMOUSLY RECOMMENDS THAT YOU VOTE ~~"FOR"~~“FOR” APPROVAL, WHICH VOTE WILL ACT TO RATIFY THE SELECTION OF PRICEWATERHOUSECOOPERS LLP.

ITEM 3: ~~APPROVAL OF AMENDMENT TO OUR RESTATED CERTIFICATE OF INCORPORATION - -------------------------------------------------------------------------------~~ Approval of Increase in the Authorized Shares of Common Stock

The ~~board~~Board believes that the proposed increase to the authorized number of ~~directors has~~shares of common stock, par value $.20 per share, is necessary for the continued success and growth of the company. The proposed ~~that we~~amendment to our Amended and Restated Certificate of Incorporation will amend ~~our restated certificate of incorporation~~Article Four to increase the number of authorized shares of common stock, par value $.20 per share, from ~~45 million~~75,000,000 shares to ~~75 million~~175,000,000 shares.

The terms of the additional shares will be the same as those that apply to our currently authorized shares. As of March 17, 2000, 33,820,026 of our 45 million authorized shares of common stock were issued and outstanding. In addition, approximately 536,617 shares were reserved for issuance pursuant to various stock-based compensation and benefit plans and 1.8 million shares were reserved for issuance in connection with a pending acquisition. As a result, there were approximately 36.1 million issued or reserved for issuance, leaving approximately 3.9 million shares of authorized common stock available for future issuances. The board believes itproposed amendment is in our best interest to increase the number of shares of authorized common stock to make available additional shares for possible future stock splits, stock dividends, employee benefit plan issuances, equity financings to raise capital, acquisitions and other corporate purposes. We have no specific plans currently calling for issuance of any of the additional shares of common stock, other than as described above. Although the proposed increase in our authorized common stock could be construed as having potential anti-takeover effects, we do not view this proposal in that perspective. Nevertheless, we could use the additional shares to frustrate persons seeking to gain control of us by, for example, privately placing shares to purchasers who might side with our board in opposing a hostile takeover bid. Shares of common stock could also be issued to persons who would thereafter have sufficient voting power to assure that any proposal to amend or repeal our by- laws or charter would not receive the required vote. Such uses of our 14 common stock could make it more difficult or discourage an attempt to gain control of us if the board opposed such transactions. Further, the issuance of additional shares could have an adverse effect on the potential realizable value of a stockholder's investment in our common stock. In the absence of a proportionate increase in our earnings and book value, an increase in the aggregate number of our outstanding shares of common stock would dilute the earnings per share and book value per share of all of our outstanding shares of common stock. These factors, if reflected in the price per share of our common stock, could adversely affect the realizable value of a stockholder's investment in our common stock. We are not aware of any attempts to obtain control of us at this time. As amended, the first sentence of Article Four of our restated certificate of incorporation would read as follows: ~~"The~~

“The aggregate number of shares of all classes of stock which the corporation shall have the authority to issue is ~~80,000,000, 75,000,000~~[180,000,000], 175,000,000 of which shall be Common Stock of the par value of $.20 per share (hereinafter called ~~"Common Stock"~~“Common Stock”) and ~~5,000,000~~[5,000,000] of which shall be Preferred Stock of the par value of $1.00 per share (hereinafter called ~~"Preferred Stock"~~“Preferred Stock”)." ”

Note that the numbers contained in the brackets above are subject to change depending on the outcome of the voting on Item No. 4 as set out in this proxy statement. If our stockholders approve Item No. 4 as well and this proposal, the numbers in the brackets above would change to 185,000,000 and 10,000,000, respectively.

46,256,646 authorized shares of common stock issued and outstanding;

530,713 shares reserved for issuance under outstanding options; and

28,212,641 authorized shares of common stock that were not reserved for any specific use and available for issuance.

If this proposal is approved, taking into account the number of shares reserved for issuance, the Board will have the authority to issue approximately 128,212,641 shares of common stock without further stockholder approval, except as may be required for a particular transaction by applicable law, regulatory agencies or the rules of the NYSE or any other securities exchange on which our securities may then be listed.

The additional authorized shares of common stock may be used for such corporate purposes as may be determined by the Board from time to time to be necessary or desirable. These purposes may include, without limitation: raising capital through the sale of common stock; effecting a stock split or issuing a stock dividend; acquiring other businesses in exchange for shares of common stock; and attracting and retaining employees by the issuance of additional securities under the company’s equity

compensation plans. At the present time, the company has no commitments, agreements or undertakings to issue any such additional shares, except in connection with existing equity compensation plans and agreements.

The Board believes that the authorized number of shares of common stock should be increased to provide the Board with the ability to issue additional shares of common stock for the potential corporate purposes described above, without having to incur the delay and expense incident to holding a special meeting of the stockholders to approve an increase in the authorized shares of common stock at that time.

The authorization of the additional shares by this proposal would not have any immediate dilutive effect on the proportionate voting power or other rights of existing stockholders, but, to the extent that the additional authorized shares are issued in the future, they may decrease existing stockholders’ percentage equity ownership and, depending on the price at which they are issued, could be dilutive to existing stockholders and have a negative effect on the market price of the company’s common stock. Under the company’s Amended and Restated Certificate of Incorporation, stockholders do not have preemptive rights with respect to the issuance of shares of common stock, which means that current stockholders do not have a prior right to purchase shares in any new issue of common stock in order to maintain their proportionate ownership of common stock.

The increase in the number of authorized shares of common stock could have an anti-takeover effect, although this is not the intent of the Board. For example, if the Board issues additional shares in the future, such issuance could dilute the stock ownership and voting power of, or increase the cost to, a person seeking to obtain control of the company, thereby deterring or rendering more difficult a merger, tender offer, proxy contest or other extraordinary transaction. To the extent that it impedes any such attempts, the proposed amendment may serve to perpetuate the Board and the company’s management. The proposed amendment is not being proposed in response to any known effort or threat to acquire control of the company and is not part of a plan by management to adopt a series of amendments to the Amended and Restated Certificate of Incorporation and the company’s bylaws having an anti-takeover effect.

In addition, other provisions of the company’s Amended and Restated Certificate of Incorporation and bylaws may have an anti-takeover effect, including provisions that require stockholders to give the company advance notice to nominate candidates for election to its Board or to make stockholder proposals at a stockholder meeting, and that permit the Board to issue, without stockholder approval, preferred stock with such terms as the Board may determine. Further, Section 203 of the Delaware General Corporation Law provides certain restrictions on business combinations between the company and any party acquiring a 15 percent or greater interest in its voting stock. These provisions of the company’s Amended and Restated Certificate of Incorporation, our bylaws, our shareholder rights plan and Delaware law could discourage potential acquisition proposals and could delay or prevent a change-in-control of the company, even if the stockholders support such proposals.

A majority of the outstanding shares or our common stock must vote FOR this proposal to approve the proposed Amendment. Abstentions and broker non-votes will have the same effect as votes against the proposal.

The Board reserves the right to abandon the proposed amendment set forth in this proposal at any time before its effectiveness whether before or after stockholder approval under Delaware General Corporation Law §242(c). If this proposal is approved, we intend to promptly file a Certificate of Amendment with the Secretary of State of the State of Delaware. On filing, all stockholders will be bound by the terms of the Certificate of Amendment, whether or not they voted to approve it.

THE BOARD ~~OF DIRECTORS~~HAS APPROVED AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE ~~IN FAVOR~~“FOR” THE APPROVAL OF ~~THIS PROPOSAL.~~ THE PROPOSED AMENDMENT.

The Board believes that the proposed increase to the authorized number of shares of preferred stock is necessary for the continued success and growth of the company. The proposed amendment to our Amended and Restated Certificate of Incorporation will amend Article Four to increase the number of authorized shares of preferred stock from 5,000,000 shares to 10,000,000 shares.

“The aggregate number of shares of all classes of stock which the corporation shall have the authority to issue is [85,000,000], [75,000,000] of which shall be Common Stock of the par value of $.20 per share (hereinafter called “Common Stock”) and 10,000,000 of which shall be Preferred Stock of the par value of $1.00 per share (hereinafter called “Preferred Stock”).”

Note that the numbers contained in the brackets above are subject to change depending on the outcome of the voting on Item No. 3 as set out in this proxy statement. If our stockholders approve Item No. 3 as well and this proposal, the numbers in the brackets above would change to 185,000,000 and 175,000,000, respectively.

Under the laws of the state of Delaware and our Amended and Restated Certificate of Incorporation, our Board has the authority, without further action by our stockholders, to issue up to 5,000,000 shares of preferred stock in one or more series and to fix the privileges and rights of each series. The Board is now requesting that the stockholders approve an increase in the number of shares of preferred stock which we can issue from 5,000,000 to 10,000,000. Currently, we do not have any shares of preferred stock outstanding.

The additional shares of preferred stock may be used for such corporate purposes as may be determined by the Board from time to time to be necessary or desirable. These purposes may include, without limitation: raising capital through the sale preferred stock; and acquiring other businesses in exchange for shares of preferred stock At the present time, the company has no commitments, agreements or undertakings to issue any such additional shares.

The Board believes that the authorized number of shares of preferred stock should be increased to provide the Board with the ability to issue additional shares of preferred stock for the potential corporate purposes described above, without having to incur the delay and expense incident to holding a special meeting of the stockholders to approve an increase in the authorized shares of preferred stock at that time.

The increase in the number of authorized shares of preferred stock could have an anti-takeover effect, although this is not the intent of the Board. For example, if the Board issues shares in the future, such issuance could dilute the stock ownership and voting power of, or increase the cost to, a person seeking to obtain control of the company, thereby deterring or rendering more difficult a merger, tender offer, proxy contest or other extraordinary transaction. To the extent that it impedes any such attempts, the proposed amendment may serve to perpetuate the company’s Board or management. The proposed amendment is not being proposed in response to any known effort or threat to acquire control of the company and is not part of a plan by management to adopt a series of amendments to the Amended and Restated Certificate of Incorporation and the company’s bylaws having an anti-takeover effect.

the company and any party acquiring a 15 percent or greater interest in its voting stock. These provisions of the company’s Amended and Restated Certificate of Incorporation, our bylaws, our shareholder rights plan and Delaware law could discourage potential acquisition proposals and could delay or prevent a change-in-control of the company, even if the stockholders support such proposals.

Types of Awards.Each type of Award that may be granted under the Plan is described below:

Stock Options. The Compensation Committee may grant non-qualified stock options or incentive stock options to purchase shares of ~~a nonqualified stock option. Upon~~common stock. The Compensation Committee will determine the number and exercise price of the ~~excess of~~options, and the time or times that the options become exercisable, provided that the option exercise price may not be less than the fair market value of a share of common stock on the ~~exercise~~ date ~~over~~of grant, except for an option granted in substitution of an outstanding award in an acquisition transaction in accordance with Section 424(h) of the Code. The term of an option will also be determined by the Compensation Committee; provided that the term of an option may not exceed 10 years.

The option exercise price ~~will~~may be ~~taxable as ordinary income~~paid in cash; by check; in shares of common stock, subject to certain limitations; through a “cashless” exercise arrangement with a broker approved in advance by us; or in any other manner authorized by the ~~participant and~~Compensation Committee. Incentive stock options will be subject to ~~applicable withholding taxes. We~~certain additional requirements necessary in order to qualify as incentive stock options under Section 422 of the Code.

Except for certain permitted adjustments, unless approved by our stockholders, (a) the exercise price for any outstanding option granted under the Plan may not be decreased after the date of grant and (b) an outstanding option that has been granted under the Plan may not, as of any date that such option has a per share exercise price that is greater than the then current fair market value of our common stock, be surrendered as consideration for the grant of a new option with a lower exercise price, shares of common stock, shares of restricted stock, restricted stock units, another “stock-based” award or a cash payment.

Restricted Stock. Shares of common stock may be granted by the Compensation Committee to an eligible employee and made subject to restrictions on sale, pledge or other transfer by the employee for a certain period (the restricted period). All shares of restricted stock will ~~generally~~ be ~~entitled~~subject to ~~a tax deduction at~~ such ~~time~~restrictions as the Compensation Committee may provide in an Award agreement with the ~~amount of such ordinary income. In~~participant, including provisions obligating the participant to forfeit or resell the shares to us in the event of ~~a sale~~termination of aemployment or if specified performance goals or targets are not met. Participant’s rights with respect to such shares shall be subject to the restrictions provided in the Award agreement and the Plan.

Restricted Stock Units. A restricted stock unit represents the right to receive from us, on the respective scheduled vesting or payment date for such restricted stock unit, one share of common stock. An award of restricted stock ~~received upon the exercise of a nonqualified stock option, any appreciation or depreciation after the exercise date will~~units may be taxed as capital gain or loss and will be long-term capital gain or loss if the requisite long-term capital gains holding period for the common stock has been satisfied. A participant who is granted an incentive stock option does not recognize taxable income at the time the option is granted or upon its exercise, although the exercise is an adjustment item for alternative minimum tax purposes and may subject ~~the participant~~ to the ~~alternative minimum tax. Upon a disposition~~attainment of specified performance goals or targets, forfeitability provisions and such other terms and conditions as the Compensation Committee may determine, subject to the provisions of the ~~shares more than two years after grant~~Plan. To the extent an award of restricted stock units is intended to qualify as performance based compensation under Section 162(m), it must be granted subject to the ~~option~~attainment of performance goals and ~~one year after exercise of~~meet the ~~option, any gain or loss is treated as long-term capital gain or loss. Net capital gains on shares held more than 12 months~~additional requirements imposed by Section 162(m).

The Compensation Committee may grant free standing stock appreciation rights, tandem stock appreciation rights or any combination of ~~20%. Capital losses are allowed~~these forms of stock appreciation rights. The grant price for each stock appreciation right shall be determined by the Compensation Committee and shall be specified in ~~full against capital gains and up to $3,000 against other income. If these holding periods are not satisfied,~~ the ~~participant recognizes ordinary income at~~Award agreement, but in no event shall the ~~time of disposition equal to the difference between the exercise~~grant price ~~and the lower of (i)~~be less than the fair market value of the shares atof common stock of the company on the date the stock appreciation right is granted. The grant price of tandem stock appreciation rights shall be equal to the option price of the related option. The term of the stock appreciation right shall be determined by the Compensation Committee and specified in the Award agreement, which relates to the stock appreciation right. No stock appreciation right will be exercised after the tenth anniversary

from the date of its grant. However, for employees employed outside the ~~option exercise~~United States and who are third-country nationals, the Compensation Committee may grant stock appreciation rights with a term of more than 10 years. Outstanding stock appreciation rights may be exercised on whatever terms the condition the Compensation Committee imposes. Tandem stock appreciation rights may be exercised for all or ~~(ii) the sale price of the shares. Any gain or loss recognized on such a premature disposition~~part of the shares ~~in excess~~subject to the related option on the surrender of the amount treated as ordinary income is treated as long-term or short-term capital gain or loss, depending on the holding period. A different rule for measuring ordinary income upon such a premature disposition may apply if the participant 17 ~~is also an officer, director, or greater than 10% stockholder. We are generally is entitled~~right to ~~a deduction in the same amount as the ordinary income recognized by the participant. The above discussion is only brief summary~~exercise equivalent portions of the amendments to the plan, the plan as amended and the tax consequences under the plan.

The following discussion provides you with certain information regarding the proposed plan. Q: Who Will Participate In The Plan? A: Only our directors who are not also employees will participate in the plan. Q: Why Has The Board Proposed That The Plan Be Adopted? A: Our board believes that our continued growth and profitability depends, in part, upon our ability to attract and retain highly qualified outside directors. One way we have achieved this objective is through the benefits we have been able to provided to our directors, including the benefits available under our current non-employee directors stock option plan. Q: How Many Shares Will Be Reserved For Issuance Under The Plan? A: 200,000 shares plus the 10,000 shares remaining available under the current plan. Q: What Will The Participants Receive? A: Each participant will receive, on the day after each annual meeting of stockholders, a nonqualified option to purchase 3,500 shares of our common stock. Currently we have five directors who are not also employees.

Q: What Is The Market Value Of The Common Stock Underlying The Options? A: The closing sales price of our common stock on February 29, 2000 was $8.125 per share. Q: Who Will Administer The Plan? A: The compensation committee of the board of directors. This committee has the authority to exercise all the powers and authorities either specifically 18 granted to it under the plan or necessary or advisable in the administration of the plan. Q: Can The Exercise Price Of An Option Be Repriced? A: No. Once an option has been granted, the plan prohibits the subsequent repricing of that option's exercise price. Q: What Happens If An Option Award Is Cancelled Or Forfeited? A: If any option granted under the plan is forfeited, canceled, or surrendered or if an option otherwise terminates or expires without having been exercised, the shares of common stockonly with respect to the shares for which the related option is unexercisable. With respect to a tandem stock appreciation right granted in connection with an incentive stock option, (a) the tandem stock appreciation right will toexpire no later than the ~~extent of any such f orfeiture, cancellation, surrender, termination or~~ expiration again be available for issuance under the plan. Q: How Will A Participant Be Entitled To Pay The Exercise Price Of An Option? A: The exercise price may be paid in cash, by the surrender of shares of common stock previously owned by the participant (provided that any shares of common stock so surrendered must have been held by participant for such period of time as may be prescribed by the committee), or a combination of cash and shares. Q: When Can A Participant Exercise An Option? A: An award will have an exercise period of ten years and can be exercised starting six months from when it is granted. Q: Can An Option Be Transferred? A: Options may not be transferred by a participant except by will or the laws of descent and distribution, may be exercised during the lifetime of a participant only by such participant or his or her guardian or legal representative and may not be subject to any encumbrance, claim or charge of any kind. Q: Can The Plan Be Amended Or Terminated? A: Yes. Our board of directors may at any time and from time to time alter, amend, suspend or terminate the plan in whole or in part. However, any such amendment will be subject to stockholder approval if and to the extent such stockholder approval is required by applicable law or the rules of the ~~national securities exchange on which~~underlying incentive stock option; (b) the ~~common stock is principally traded. Notwithstanding the foregoing, no amendment, suspension or termination may affect adversely any~~value of the rights of a participant under an outstanding award without such participant's consent. Unless earlier terminated by the board pursuant to the provisions of the plan, the plan will terminate on May 20, 2010. Q: What Are The Federal Income Tax Consequences Of Awards Under The Plan? A: A participant will not recognize any taxable income upon the grant of a nonqualified stock option, and we will not be entitled to a tax deductionpayout with respect to the ~~grant~~tandem stock appreciation right will be for no more than 100% of the difference between the option price of the underlying incentive stock option and the fair market value of the shares subject to the underlying incentive stock option at the time the tandem stock appreciation right is exercised; and (c) the tandem stock appreciation right may be exercised only when the fair market value of the shares subject to the incentive stock option exceeds the option price of the incentive stock option.

On the exercise of a ~~nonqualified~~ stock ~~option. Upon exercise,~~appreciation right, a participant will be entitled to receive payment in an amount determined by multiplying: (a) the ~~excess of~~difference between the fair market value of a share of common stock on the date of exercise and the grant price; by (b) the number of shares with respect to which the stock appreciation right is exercised. In the discretion of the Compensation Committee, the payment of the stock appreciation right exercised may be in cash, shares of equivalent value (based on the fair market value on the date ~~over~~of exercise of a stock appreciation right) in some combination thereof or in any other form approved by the ~~option~~Compensation Committee.

Other Stock-Based Awards. The Plan also authorizes the Compensation Committee to grant participants awards of common stock and other awards that are denominated in, payable in, valued in whole or in part by reference to, or are otherwise based on the value of, or the appreciation in value of, shares of common stock (other stock-based awards). The Compensation Committee has discretion to determine the participants to whom other stock-based awards are to be made, the times at which such awards are to be made, the size of such awards, the form of payment, and all other conditions of such awards, including any restrictions, deferral periods or performance requirements.

Performance-Based Compensation Under Section 162(m). Stock options and stock appreciation rights granted in accordance with the terms of the Plan, the exercise ~~price~~of which is based on the attainment of performance goals, will qualify as performance-based compensation under Section 162(m). Grants of any restricted stock, restricted stock units or other stock-based awards that we intend to qualify as performance-based compensation under Section 162(m) must be made subject to the achievement of pre-established performance goals. The pre-established performance goals will be ~~taxable~~based on any or a combination of the following business criteria applied to our company as ~~ordinary~~a whole, a company division or a subsidiary:

(j)

Share price (including, but not limited to, growth measures and total shareholder return);

Any performance goal (s) may be used to measure the performance of the company as a whole or any business unit of the company or any combination thereof, as the Compensation Committee may deem appropriate, or any of the above performance measures as compared to the ~~participant~~performance of a group of comparative companies, or published or special index that the Compensation Committee, in its sole discretion, deems appropriate.

The Compensation Committee has authority to use different targets from time to time under the performance goals provided in the Plan. As a result, the regulations under Section 162(m) require that the material terms of the performance goals be re-approved by the stockholders every five years. To qualify as performance-based compensation, grants of restricted stock, restricted stock units and other stock-based awards will be ~~subject~~required to satisfy the other applicable ~~withholding taxes. We will generally~~requirements of Section 162(m).

Termination of Employment.If a participant ceases to be ~~entitled~~employed by us or provide services to ~~a tax deduction~~us for any reason, including death, his outstanding Awards may be exercised or shall expire at such time or times as may be determined by the Compensation Committee and described in the ~~amount of such ordinary income.~~ Award agreement.

Change-in- Control.In the event of a change-in-control of our company, as defined in the Plan, all Awards will become fully vested and exercisable, all restrictions or limitations on any Awards will generally lapse and, unless otherwise provided in the Award agreement, all performance criteria and other conditions relating to the payment of Awards will generally be deemed to be achieved or waived.

Transferability of Awards.The Awards awarded under the Plan may not be transferred except

by the laws of descent and distribution;

in the case of non-qualified stock options only, if permitted by the Compensation Committee and if so provided in the Award agreement.

Payment of Withholding Taxes.We may withhold from any payments or stock issuances under the Plan, or collect as a condition of payment, any taxes required by law to be withheld. Any participant may, but is not required to, satisfy his or her withholding tax obligation by electing to deliver currently owned shares of common stock or to have us withhold, from the shares the participant would otherwise receive, shares of common stock, in each case having a value equal to the minimum amount required to be withheld. This election must be made before the date on which the amount of tax to be withheld is determined and is subject to the Compensation Committee’s right of disapproval.

If our stockholders approve the Plan at the annual meeting, grants of awards to selected employees will be made in the future by the Compensation Committee as necessary to attract and retain employees.

Under existing federal income tax provisions, a participant who is granted a stock option normally will not realize any income, nor will we normally receive any deduction for federal income tax purposes, in the year the option is granted.

When a non-qualified stock option granted under the Plan is exercised, the participant will realize ordinary income measured by the difference between the aggregate purchase price of the shares of common stock acquired and the

aggregate fair market value of the shares of common stock acquired on the exercise date and, subject to the limitations of Section 162(m) of the Code, we will be entitled to a deduction in the year the option is exercised equal to the amount the participant is required to treat as ordinary income.

An employee generally will not recognize any income upon the exercise of any incentive stock option, but the excess of the fair market value of the shares at the time of exercise over the option price will be an item of tax preference, which may, depending on particular factors relating to the employee, subject the employee to the alternative minimum tax imposed by Section 55 of the Code. The alternative minimum tax is imposed in addition to the federal individual income tax, and it is intended to ensure that individual taxpayers do not completely avoid federal income tax by using preference items. An employee will recognize capital gain or loss in the amount of the difference between the exercise price and the sale price on the sale or exchange of stock acquired pursuant to the exercise of an incentive stock option, provided the employee does not dispose of such stock within two years from the date of grant and one year from the date of exercise of the incentive stock option (the holding periods). An employee disposing of such shares before the expiration of the holding periods will recognize ordinary income generally equal to the difference between the option price and the fair market value of the stock on the date of exercise. The remaining gain, if any, will be capital gain. We will not be entitled to a ~~share~~federal income tax deduction in connection with the exercise of an incentive stock option, except where the employee disposes of the shares of common stock received upon exercise before the expiration of the holding periods.

If the exercise price of a non-qualified option is paid by the surrender of previously owned shares, the basis and the holding period of the previously owned shares carry over to the same number of shares received in exchange for the previously owned shares. The compensation income recognized on exercise of these options is added to the basis of the shares received. If the exercised option is an incentive stock option and the shares surrendered were acquired through the exercise of ~~a nonqualified 19~~ an incentive stock option ~~any appreciation or depreciation after~~and have not been held for the ~~exercise date~~holding periods, the optionee will recognize income on such exchange, and the basis of the shares received will be ~~taxed as capital gain or loss and~~equal to the fair market value of the shares surrendered. If the applicable holding period has been met on the date of exercise, there will be ~~long-term capital gain~~no income recognition and the basis and the holding period of the previously owned shares will carry over to the same number of shares received in exchange, and the remaining shares will begin a new holding period and have a zero basis.

If, on a change-in-control of our company, the exercisability or ~~loss~~vesting of an Award is accelerated, any excess on the date of the change-in-control of the fair market value of the shares or cash issued under accelerated Awards over the purchase price of such shares, if any, may be characterized as “parachute payments” (within the meaning of Section 280G of the Code) if the ~~requisite long-term capital gains holding period~~sum of such amounts and any other such contingent payments received by the employee exceeds an amount equal to three times the “base amount” for such ~~common stock has been satisfied.~~employee. The ~~above discussion~~base amount generally is ~~only brief summary~~the average of the annual compensation of such employee for the five years preceding such change in ownership or control. An “excess parachute payment,” with respect to any employee, is the excess of the parachute payments to such person, in the aggregate, over and above such person’s base amount. If the amounts received by an employee upon a change-in-control are characterized as parachute payments, such employee will be subject to a 20% excise tax on the excess parachute payment and we will be denied any deduction with respect to such excess parachute payment.

If there are no such sale price quotations for the date as of which fair market value is to be determined but there are such sale price quotations within a reasonable period both before and after such date, then fair market value shall be determined by taking a weighted average of the means between the highest and lowest sales prices per share of the Common Stock as so quoted on the nearest date b efore and the nearest date after the date as of which fair market value is to be determined. The average should be weighted inversely by the respective number of trading days between the selling dates and the date as of which fair market value is to be determined. If there are no such sale price quotations on or within a reasonable period both before and after the date as of which fair market value is to be determined, then fair market value of the Common Stock shall be the mean between the bona fide bid and asked prices per share of Common Stock as so quoted for such date on NASDAQ, or if none, the weighted average of the means between such bona fide bid and asked prices on the nearest trading date before and the nearest trading date after the date as of which fair market value is to be determined, if both such dates are within a reasonable period.

If the outstanding shares of the Common Stock shall be changed into or exchangeable for a different number or kind of shares of stock, other securities or other property of the Company or another corporation, whether through reorganization, reclassification, recapitalization, stock split-up, combination of shares, merger or consolidation, then there shall be substituted for each share of the Common Stock set forth in Section 3, for each share of the Common Stock subject to any then outstanding s tock option, and for each share of the Common Stock which may be issued or delivered under the Plan but which is not then subject to any outstanding stock option, the number and kind of shares of stock or other securities into which each outstanding share of the Common Stock shall be so changed or for which each such share shall be exchangeable. B-5 In case of any adjustment or substitution as provided for in this Section 5, the aggregate option price for all shares subject to each then outstanding stock option prior to such adjustment or substitution shall be the aggregate option price for all shares of stock or other securities (including any fraction) to which such shares shall have been adjusted or which shall have been substituted for such shares. Any new option price per share shall be carried to at least three decimal places with the last decimal place rounded upwards to the nearest whole number. No adjustment or substitution provided for in this Section 5 shall require the Company to issue or deliver or sell a fraction of a share or other security. Accordingly, all fractional shares or other securities, which result from any such adjustment or substitution, shall be eliminated and not carried forward to any subsequent adjustment or substitution.

In no case may the Committee increase the value of an Award of Performance-Based Compensation above the maximum value determined under the performance formula by the attainment of the applicable Performance Goal(s), but the Committee may retain the discretion to reduce the value below such maximum.

Unless and until the Committee proposes for shareholder vote and the shareholders approve a change in the general Performance Measures set forth in this Article 11, the Performance Goal(s) on which the ~~Common Stock~~payment or vesting of an Award to an Insider that is intended to qualify as Performance-Based Compensation shall be limited to the following Performance Measures:

In the Award Agreement, the Committee also has the authority to provide for accelerated vesting of any Award based on the achievement of Performance Goal(s).

In the event that applicable tax and/or securities laws change to permit Committee discretion to alter the governing Performance Measures without obtaining shareholder approval of such changes, the Committee shall have sole discretion to make such changes without obtaining shareholder approval.

(d) On a Change of Control, unless otherwise specifically provided in a written agreement entered into between the Participant and the Company or an Affiliate, the Committee shall immediately vest and pay out all Cash-Based Awards and Other Stock-Based Awards as determined by the Committee.
