(1) The closing price per share on September 28, 2001, was $7.11 as reported by the Nasdaq National Market. Defined Benefit Plans and Other Arrangements. Long-term incentive compensation for senior executive officers is not a policy of the Company. Accordingly, no awards or payouts have been made. The Company has no retirement or pension plan except for its Employee Stock Purchase Plan and its Incentive Stock Option Plans, all of which are described below. Directors who are not also employees of the Company receive $1,000 per month and 500 shares of Common Stock per year for serving as directors. 4

COMPENSATION PLANS Stock Option Plans. The Dawson Geophysical Company 1991 Incentive Stock Option Plan (the "1991 Plan") provided that 150,000 shares of the Company's authorized but unissued Common Stock are reserved for issuance pursuant to the 1991 Plan and are subject to options granted to key employees during the ten-year period through January 8, 2001. The Dawson Geophysical Company 2000 Incentive Stock Plan provides an additional 500,000 shares reserved for issuance. The 2000 Plan contains substantially the same terms as the predecessor plan except up to 50,000 of such shares may be awarded and issued as additional compensation to key employees, officers and non-employee members of the Board of Directors of the Company with or without payment therefor. The 2000 Plan covers a ten-year period through January 12, 2009. All outstanding options under the original plan will not be affected by the 2000 Plan. Options under the 2000 Plan are granted at an exercise price equal to the market price of the stock on the date of grant. Each option that is granted is exercisable after the period or periods specified in the option agreement, but prior to the expiration of five years after the date of grant. Commencing one year after date of grant, optionees may purchase up to one-fourth of the shares covered by a particular grant, and each option becomes exercisable with respect to an additional one-fourth of the shares covered in each of the next three years. During fiscal 2001, no shares of the Common Stock were issued pursuant to the exercise of options granted under the 1991 Plan. During fiscal 2001, options to purchase 70,000 shares of common stock were granted to employees of the Company under the 2000 Plan. As of November 26, 2001, the total number of shares covered by outstanding options was 251,000. Stock Purchase Plan. On November 1, 1982, as amended September 28, 1999, the Board of Directors of the Company adopted an Employee Stock Purchase Plan (the "Purchase Plan") effective January 1, 1983, in which eligible employees may elect to purchase, through payroll deductions, shares of the Company's Common Stock and thereby increase their proprietary interest in the Company. Pursuant to the Purchase Plan, the Company contributes one dollar (before Social Security and withholding taxes) for each dollar contributed by an eligible employee to purchase Common Stock for the employee's account up to 5% of the employee's annual salary. As of September 30, 2001, no named executive officers participated in the Purchase Plan. On a bi-weekly basis, the Company matches the participants' percentage of contributions and directs the purchase of shares of the Company's Common Stock. There are no vesting requirements for the participants. The Company contributed $214,347, $240,328 and $223,360 to the Purchase Plan during the fiscal years 1999, 2000 and 2001, respectively. BOARD REPORT ON EXECUTIVE COMPENSATION Compensation for executive officers is based on the principle that compensation must be competitive to enable the Company to motivate and retain the talent needed to lead and grow the Company's business, and to provide rewards which are closely linked to the Company and individual performance. Executive compensation is based on performance against a combination of financial and non-financial measures. In addition to business results, employees are expected to uphold a commitment to integrity, maximizing the development of each individual, and continually improving the environmental quality of its services and operations. In upholding these financial and non-financial objectives, executives not only contribute to their own success, but also help ensure that the business, employees, stockholders and communities in which we live and work will prosper. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION The Company's Compensation Committee makes recommendations regarding compensation subject to approval of the entire Board of Directors. REPORT OF THE AUDIT COMMITTEE To the Stockholders of Dawson Geophysical Company: It is the responsibility of the members of the Audit Committee to contribute to the reliability of the Company's Financial Statements. In keeping with this goal, the Board of Directors adopted a written charter in May 2000 (attached to this proxy statement as Exhibit A) to govern the Audit Committee. Upon evaluation of the charter's adequacy in 2001, the Audit Committee is satisfied. In addition to written consent, the Audit Committee met three times during fiscal 2001. The members of the Audit Committee are independent directors. The Audit Committee has reviewed and discussed the Company's audited financial statements with management. It has also discussed with the independent auditors the matters required to be discussed by Statement on Accounting Standards No. 61, Communication with Audit Committees, as amended, by the Auditing Standards Board of the American Institute of Certified Public Accountants. Additionally, the Audit Committee has received the written disclosures and the letter from the independent accountants at KPMG LLP, as required by Independent Standards Board Standard No. 1 (Independence Discussions with Audit Committees) and has discussed with the independent accountants that firm's independence from the Company and its management. The Audit Committee has concluded that non-audit services provided by KPMG LLP do not result in conflict in maintaining that firm's independence. 5

Audit fees billed to the Company by KPMG LLP during the Company's 2001 fiscal year for the audit of the Company's annual financial statements and the review of those financial statements included in the Company's quarterly reports of Form 10-Q totaled approximately $30,000. The Company was billed approximately $14,000 by KPMG LLP for tax related services. The Company has obtained no other services from KPMG LLP. Based on reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the financial statements for fiscal 2001 be included in the Company's Annual Report on Form 10-K.
