WESTERN NATIONAL BANK

508 WEST WALL STREET, SUITE 1100

		 	RE: Revolving Line of Credit Loan in the amount of $20,000,000.00 from
Western National Bank to Dawson Geophysical Company

Gentlemen:

Pursuant to the terms of a letter loan agreement, dated as of June 2, 2008 (the “Existing Loan
Agreement”), Western National Bank, a national banking association (alternatively, “Western” or the
“Bank”), has previously committed to provide to Dawson Geophysical Company, a Texas corporation
(alternatively, “Dawson Geophysical” or the “Borrower”), a revolving line of credit loan in the
original principal amount of Forty Million and No/Dollars ($40,000,000.00) (the Existing Loan”).
The Existing Loan is evidenced by a Revolving Line of Credit Note, also dated as of June 2, 2008,
executed by the Borrower on behalf of Western, in the original principal amount of Forty Million
and No/100 Dollars ($40,000,000.00) (the “Existing Note”). The Existing Note is secured by that
certain Security Agreement, also dated as of June 2, 2008, covering those accounts receivable
described therein (the “Existing Security Agreement”). From time to time, the Existing Security
Agreement, and any financing statements filed to perfect the security interest created thereunder,
may be collectively referred to herein as the “Existing
Security Instruments”.

Borrower has now
requested that Western renew and extend the Existing Loan into a new revolving line of credit loan
in the original principal amount of Twenty Million and No/100 Dollars ($20,000,000.00) (the
“Loan”). The Loan will be evidenced by a Revolving Line of Credit Note, of even date herewith,
executed by the Borrower in favor of Western, in the original principal amount of Twenty Million
and No/100 Dollars ($20,000,000.00), which as stated, will renew and extend the Existing Note (the
“Note”). The Borrower’s performance under the Note will be secured by its execution of a new
Security Agreement, of even date herewith, the security interest of which will be perfected by the
filing of amendments to the existing financing statement, covering all accounts receivable and
equipment described therein (collectively, the “Security Instruments”). This Agreement, as
defined below, the Note, the Security Instruments, and any

1

 

other documents executed simultaneously herewith are collectively referred to as the “Loan
Documents”.

Western has agreed to renew the Existing Loan into the Loan. In consideration of
Western’s agreement to renew the Existing Loan into the Loan, Borrower has agreed to execute this
Loan Agreement, the Note, and the Security Instruments required by the Bank, subject to the
fulfillment of the following terms and conditions of this letter loan agreement (the “Agreement”):

I.         TERMS

Agreement

This Agreement, dated as of June 2, 2009, and any extensions, renewals, or modifications hereof.

Borrower

Dawson Geophysical Company

Bank

Western National Bank

Commitment

The lesser of the following amounts: (a) the face amount of the Note; or (b) the Borrowing Base
then in effect.

Rate

From June 1, 2009 through June 30, 2009, interest under the Note shall accrue at an annual rate
equal to the Prime Rate, minus three-quarters of one percent (.75%) (the “Prime Rate Index”).
Beginning as of July 1, 2009, interest under the Note shall accrue at an annual rate equal to
either: (a) the 30-day London Interbank Offered Rate (“LIBOR”), plus two and one-quarter percent
(2.25%), or (b) the Prime Rate Index, as the Borrower shall choose monthly by notifying the Bank
in writing, via facsimile or e-mail, by the last day of each month, with each change to be
effective as of the first day of the following month, provided that such interest rate shall not
exceed the Highest Lawful Rate, as defined in the Note, or be less than four percent (4.0%).
Should Borrower fail to notify Bank of its election of interest rate for any given month, the
interest rate shall remain at the interest rate index chosen by Borrower for the immediately
preceding month.

For purposes of this Agreement, LIBOR shall mean, with respect to each Interest Period, as defined
below, the rate as established as the 30-day LIBOR in the money rate table of The Wall Street
Journal, a Dow Jones publication, as of each Business Day, as defined below (and for holidays or
weekends, LIBOR shall be the 30-day LIBOR published in that money rate table of

2

 

The Wall Street Journal, as of the close of business on the most recent Business Day immediately
preceding such weekend or holiday). Without notice to the Borrowers or any other person, LIBOR may
change from time to time pursuant to the preceding sentence, with the effective date of each change
to be the effective date reflected in the money rate table of The Wall Street Journal. Without
notice to the Borrowers or any other person, LIBOR may change from time to time pursuant to the
preceding sentence, with the effective date of each change to be the effective date reflected in
the money rate table of The Wall Street Journal. Each change in LIBOR to be charged on the Revolver
Note will become effective without notice on the commencement of each Interest Period based upon
the Index then in effect. “Interest Period” means each consecutive one month period (the first of
which shall commence on June 1, 2009), effective as of the first day of each Interest Period and
ending on the last day of each Interest Period, provided that if any Interest Period is scheduled
to end on a date for which there is no numerical equivalent to the date on which the Interest
Period commenced, then it shall end instead on the last day of such calender month. For purposes of
this Agreement, the “Prime Rate” shall be defined as that rate established as the prime rate in the
money rate table of The Wall Street Journal, a Dow Jones publication, as of each Business Day, as
hereinafter defined, (and for holidays or weekends, the Prime Rate shall be the prime rate
published in that money rate table of The Wall Street Journal, as of the close of business on the
most recent Business Day immediately preceding such weekend or holiday). Without notice to the
Borrower or any other person, the Prime Rate may change from time to time pursuant to the preceding
sentence, with the effective date of each change to be the effective date reflected in the money
rate table of The Wall Street Journal. The Prime Rate is a reference rate and does not necessarily
represent the lowest or best rate actually charged to any customer. The Bank may make commercial
loans or other loans at rates of interest at, above, or below the Prime Rate. “Business Day” shall
mean any day other than a Saturday, Sunday or legal holiday for commercial banks under the laws of
the State of Texas.

Security

The Loan shall be secured by the Security Instruments.

Structure

Under the Note, funds will be available on a revolving basis through June 2, 2011, the maturity
date of the Loan (the “Revolving Period”). During the Revolving Period, the Borrower may borrow,
repay, and re-borrow funds as long as the aggregate amount (including outstanding letters of
credit) does not exceed the Commitment.

Borrowing Base

At any time, and from time to time, the amounts outstanding under the Revolver Note shall not
exceed the lesser of: (a) the face amount of the Revolver Note; or (b) the Borrowing Base, as
determined from time to time by the Bank, acting in its sole and unlimited discretion (said lesser
amount being referred to herein as the “Revolver Commitment”). As used in this Agreement, the term
“Borrowing Base” shall mean an amount equal to eighty percent (80%) of Borrower’s Eligible
Accounts.

3

 

For the purposes of this Agreement, the term “Eligible Account” shall mean an account receivable
of the Borrower (net of any credit balance, trade discount, or unbilled amount or retention) that
is contractually due, for which each of the following statements is accurate and complete (and the
Borrower, by including such account receivable in any computation of the Borrowing Base, shall be
deemed to represent and warrant to the Bank the accuracy and completeness of such statements):

	 	a.	 	Said account receivable is a binding and valid obligation of the obligor
thereon, in full force and effect, and enforceable in accordance with its terms;
	 
	 	b.	 	Said account receivable is genuine, in all respects, as appearing on its face
as represented in the books and records of Borrower, and all information set forth
therein is true and correct;
	 
	 	c.	 	Said account receivable is free of all default of any party thereto,
counterclaims, offsets, and defenses, and from any rescission, cancellation, or
avoidance, and all right thereof, whether by operation of law or otherwise;
	 
	 	d.	 	The payment of said account receivable is not more than ninety (90) days past
due the invoice date thereof;
	 
	 	e.	 	Said account receivable is free of concessions or understandings with the
obligor thereon of any kind not disclosed to and approved by the Bank in writing;
	 
	 	f.	 	Said account receivable is, and at all times will be, free and clear of all
liens except those in favor of the Bank;
	 
	 	g.	 	Said account receivable is not a receivable arising from intercompany
indebtedness existing between or among any of the Borrower;
	 
	 	h.	 	Said account receivable is derived from sales made or services rendered to the
obligor in the ordinary course of the business of the Borrower;
	 
	 	i.	 	The obligor on said account receivable (i) is located within the United States or the
District of Columbia; (ii) is not the subject of any bankruptcy or insolvency
proceeding, nor has a trustee or receiver been appointed for all or a substantial
part of its property, nor has said obligor made an assignment for the benefit of
creditors, admitted its inability to pay its debts as they mature or suspended its
business, (iii) is not affiliated, directly or indirectly, with Borrower, as a
subsidiary or affiliate, employee or otherwise; and (iv) is not a state or federal
government department, commission, board, bureau, or agency;
	 
	 	j.	 	Said account receivable is not owed by a customer whose principal place of
business is located in a foreign country; and

4

 

	 	k.	 	Said account receivable did not arise from sales to an obligor as to whom fifteen
percent (15%) or more of the total accounts receivable owing by such obligor to the
Borrower are delinquent accounts receivable (that is, an account that is more than
ninety (90) days delinquent).

In addition to the criteria stated above for determining whether an account receivable is an
“Eligible Account”, the Bank and the Borrower agree that no such account receivable shall
constitute an Eligible Account if that account receivable arises from any single customer, other
than Client A and its affiliates and subsidiaries (collectively,
“Client A”), whose accounts receivable constitute more than twenty-five percent (25%) of
Borrower’s total accounts receivable. The Bank agrees that an account receivable owed by Client A
to the Borrower (collectively, the “Client A Accounts”) may still qualify as an Eligible Account
even if the Client A Accounts constitute more than twenty-five percent (25%) of Borrower’s total
accounts receivable.

Based upon the terms of this Agreement, and the information provided and the representations made
by the Borrower to the Bank, the Bank hereby redetermines the Borrowing Base, and establishes it
in the amount of Twenty Million and No/100 Dollars ($20,000,000.00). The Borrower may request in
writing an additional increase in the Borrowing Base, such request to be accompanied by a
description and evaluation of any additional collateral to be provided by the Bank. The Bank may
evaluate such for an increase in its sole and absolute discretion, and in conjunction with such
evaluation, may conduct a full credit analysis of the Borrower and the existing or additional
collateral.

If the aggregate amounts outstanding under the Note exceeds the Revolver Commitment at any time,
the Bank will provide written notice of that event to Borrower. On or before the tenth
(10th) day following receipt of such notification by Borrower, Borrower will either, at
the direction of the Bank, acting in its sole and absolute discretion: (a) make a mandatory
payment to the Bank of the principal of the Note in an amount at least equal to the amount
necessary to cause the outstanding principal balance of the Note to be less than or equal to the
Revolver Commitment; or (b) create liens on other assets of Borrower, satisfactory in nature,
quantity, and value to the Bank, acting in its sole discretion, said assets to have a fair market
value sufficient to at least equal to the amount necessary to cause the outstanding principal
balance of the Note to be less than or equal to the Revolver Commitment.

Non-Recourse

Although the Borrower is responsible on a corporate basis for the full repayment of principal and
interest due on the Obligations and for any other Event of Default for which the Borrower is
responsible, the Bank specifically acknowledges and agrees that neither any of the directors,
officers, or employees of the Borrower nor any of the Borrower’s shareholders shall have any
personal liability whatsoever for the repayment of the Loan. The sole party responsible for
repayment of the Loan shall be the Borrower, and the sole security for the Loan shall be the
Collateral covered by the Security Instruments.

5

 

Purpose

Funds from the Loan shall be to renew and extend the Existing Loan and to provide additional funds
for working capital. No proceeds from the Loan shall be used for the purpose of purchasing or
carrying margin stock in violation of Regulations G, U, or X of the Board of Governors of the
Federal Reserve System.

As stated, the maturity date of the Note is June 2, 2011.

regulation. There do not exist upon any property owned by Borrower any underground storage tanks or
facilities, and to the knowledge of Borrower, none of such property has ever been used for the
treatment, storage, recycling, or disposal of any Hazardous Materials.

(b) availability under the Revolver Loan, divided by (c) current liabilities. Current assets shall
include a minimum balance of cash, plus marketable securities, of not less than $3,500,000.00,
provided that this requirement is only applicable if funds are outstanding under the Note.

     9. Borrower shall submit copies of all financial statements, reports, notices, and proxy
