 REVOLVING PROMISSORY NOTE 

 

			
	$50,000,000.00	  	September 27, 2013

 For value received, GEOSPACE TECHNOLOGIES CORPORATION, a Delaware corporation
(“Borrower”), does hereby promise to pay to the order of FROST BANK, a Texas state bank (“Lender”), at P.O. Box 34746, San Antonio, Texas 78265, or at such other address as Lender shall from time to time
specify in writing, in lawful money of the United States of America, the sum of FIFTY MILLION AND NO/100 DOLLARS ($50,000,000.00), or so much thereof as from time to time may be disbursed by Lender to Borrower under the terms of that certain Loan
Agreement dated of even date herewith between Borrower, Guarantor (as defined therein) and Lender (the “Loan Agreement”), and be outstanding, together with interest from the date hereof on the principal balance outstanding from time
to time as hereinafter provided. Interest shall be computed on a per annum basis of a year of 360 days and for the actual number of days elapsed, unless such calculation would result in a rate greater than the highest rate permitted by applicable
law, in which case interest shall be computed on a per annum basis of a year of 365 days or 366 days in a leap year, as the case may be. Any capitalized terms used in this Note and not otherwise defined herein shall have the meaning ascribed to them
in the Loan Agreement. 
 1. Payment Terms. Interest only on amounts outstanding hereunder shall be due and payable monthly as it
accrues, on the 1st day of each and every calendar month, beginning November 1, 2013, and continuing regularly and monthly thereafter until April 27, 2016, when the entire amount hereof, principal and accrued interest then remaining
unpaid, shall be then due and payable; interest being calculated on the unpaid principal each day principal is outstanding and all payments made credited to any collection costs and late charges, to the discharge of the interest accrued and to the
reduction of the principal, in such order as Lender shall determine. 
 2. Interest Rate. 

(a) The interest rate is a rate per year equal to the lesser of (i) the Wall Street Journal LIBOR Rate (as defined in
clause (c) below) plus the Applicable Margin (as defined in clause (d) below), or (ii) the Maximum Rate. 

(b) The interest rate will be adjusted on the first (1st) day of each
quarter (the “Adjustment Date”) and remain fixed until the next successive Adjustment Date. If the Adjustment Date in any particular quarter would otherwise fall on a day that is not a Business Day then, at Lender’s option, the
Adjustment Date for that particular month will be the first Business Day immediately following thereafter. 
 (c) The Wall
Street Journal LIBOR Rate is a rate of interest equal to the one month London interbank offered rate as published in the “Money Rates” section of The Wall Street Journal (or, if such source is not available, such alternate
source as determined by Lender reasonably and in good faith) on the banking day immediately preceding the Adjustment Date, as adjusted from time to time in Lender’s sole discretion for reserve requirements, deposit insurance assessment rates
and other regulatory costs. 

 (d) The Applicable Margin shall be the following amounts per annum, based upon
the ratio of Funded Debt to EBITDA, as set forth in the most recent compliance certificate (or, if no compliance certificate is required, the Borrower’s most recent financial statements) received by Lender as required in the Loan Agreement;
provided, however, that, until Lender receives the first compliance certificate or financial statement, such amounts shall be those indicated for pricing level 4 set forth below: 

 

							
	 Pricing Level
	  	Funded Debt to EBITDA	  	Wall Street Journal
LIBOR Rate +	 
	 1
	  	> 1.50	  	 	3.25	% 
	 2
	  	1.50 >, but > 1.25	  	 	3.00	% 
	 3
	  	1.25>, but > 1.00	  	 	2.75	% 
	 4
	  	<1.00	  	 	2.50	% 

 The ratio of Funded Debt to EBITDA will be calculated at the end of each reporting period for which Lender
requires financial statements, using the results of the twelve-month period ending with that reporting period. The Applicable Margin shall be in effect from the date the most recent compliance certificate or financial statement is received by Lender
until the date the next compliance certificate or financial statement is received; provided, however, that if Borrower fails to timely deliver the next compliance certificate or financial statement, the Applicable Margin from the date such
compliance certificate or financial statement was due until the date such compliance certificate or financial statement is received by Lender shall be the highest pricing level set forth above. 

3. Late Charge. If a payment is made more than 10 days after it is due, Borrower will be charged, in addition to interest, a delinquency
charge of (a) 5% of the unpaid portion of the regularly scheduled payment, or (b) $250.00, whichever is less. Additionally, upon maturity of this Note, if the outstanding principal balance (plus all accrued but unpaid interest) is not paid
within 10 days of the maturity date, Borrower will be charged a delinquency charge of (i) 5% of the sum of the outstanding principal balance (plus all accrued but unpaid interest), or (ii) $250.00, whichever is less. Borrower agrees with
Lender that the charges set forth herein are reasonable compensation to Lender for the handling of such late payments. 
 4. Default
Rate. For so long as any Event of Default exists, regardless of whether or not there has been an acceleration of the indebtedness evidenced by this Note, and at all times after the maturity of the indebtedness evidenced by this Note (whether by
acceleration or otherwise), and in addition to all other rights and remedies of Lender hereunder, interest shall accrue at the applicable rate stated in Section 2 above plus two percent (2%) per annum, but in no event in excess of
the Maximum Rate, and such accrued interest shall be immediately due and payable. Borrower acknowledges that it would be extremely difficult or impracticable to determine Lender’s actual damages resulting from any Event of Default, and such
accrued interest is a reasonable estimate of those damages and does not constitute a penalty. 
 5. Revolving Line of Credit. Under
the Loan Agreement, Borrower may request advances and make payments hereunder from time to time, provided that it is understood and agreed that the aggregate principal amount outstanding from time to time hereunder shall not at any time exceed the
Revolving Credit Commitment minus the Letter of Credit Liabilities. The 

  
 2 

 
unpaid balance of this Note shall increase and decrease with each new advance or payment hereunder, as the case may be. This Note shall not be deemed terminated or canceled prior to the date of
its maturity other than in accordance with the terms of the Loan Agreement, although the entire principal balance hereof may from time to time be paid in full. Borrower may borrow, repay and re-borrow hereunder. All payments and prepayments of
principal or interest on this Note shall be made in lawful money of the United States of America in immediately available funds, at the address of Lender indicated above, or such other place as the holder of this Note shall designate in writing to
Borrower. If any payment of principal or interest on this Note shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and any such extension of time shall be included in computing
interest in connection with such payment. The books and records of Lender shall be prima facie evidence of all outstanding principal of and accrued and unpaid interest on this Note. 

6. Prepayment. Borrower reserves the right from time to time to prepay, prior to maturity, all or any part of the principal of this Note
without premium or penalty. Any prepayments shall be applied first to accrued interest and then to principal. Borrower will provide written notice to the holder of this Note of any such prepayment of all or any part of the principal at the time
thereof. All payments and prepayments of principal or interest on this Note shall be made in lawful money of the United States of America in immediately available funds, at the address of Lender indicated above, or such other place as the holder of
this Note shall designate in writing to Borrower. 
 7. Default. It is expressly provided that upon the occurrence and during the
continuance of an Event of Default the holder of this Note may, at its option, exercise the remedies of Lender provided in Section 9.02 of the Loan Agreement; and in the event default is made in the prompt payment of this Note when due or
declared due, and the same is placed in the hands of an attorney for collection, or suit is brought on same, or the same is collected through probate, bankruptcy or other judicial proceedings, then the Borrower agrees and promises to pay all
out-of-pocket costs of collection, including reasonable attorney’s fees. 
 8. No Usury Intended; Usury Savings Clause. In no
event shall interest contracted for, charged or received hereunder, plus any other charges in connection herewith which constitute interest, exceed the Maximum Rate. The amounts of such interest or other charges previously paid to the holder of the
Note in excess of the amounts permitted by applicable law shall be applied by the holder of the Note to reduce the principal of the indebtedness evidenced by the Note, or, at the option of the holder of the Note, be refunded. To the extent permitted
by applicable law, determination of the Maximum Rate shall at all times be made by amortizing, prorating, allocating and spreading in equal parts during the period of the full stated term of the loan and indebtedness, all interest at any time
contracted for, charged or received from the Borrower hereof in connection with the loan and indebtedness evidenced hereby, so that the actual rate of interest on account of such indebtedness is uniform throughout the term hereof. 

9. Security. This Note has been executed and delivered pursuant to the Loan Agreement and is secured by a Security Agreement of even
date herewith, by and among Borrower, each of the domestic subsidiaries of Borrower identified on Schedule 1 hereto and Lender, covering certain collateral as more particularly described therein. The holder of this Note is entitled to
the benefits and security provided in the Loan Documents.

 10. Joint and Several Liability; Waiver. Each maker, signer, surety and endorser hereof,
as well as all successors and assigns of said parties, shall be directly and primarily, jointly and severally, liable for the payment of all indebtedness hereunder. Lender may release or modify the obligations of any of the foregoing persons or
entities, or guarantors hereof, in connection with this Note without affecting the obligations of the others. All such persons or entities expressly waive presentment and demand for payment, notice of default, notice of intent to accelerate
maturity, notice of acceleration of maturity, protest, notice of protest, notice of dishonor, and all other notices and demands for which waiver is not prohibited by law, and diligence in the collection hereof; and agree to all renewals, extensions,
indulgences, partial payments, releases or exchanges of collateral, or taking of additional collateral, with or without notice, before or after maturity. No delay or omission of Lender in exercising any right hereunder shall be a waiver of such
right or any other right under this Note. 
 11. Texas Finance Code. In no event shall Chapter 346 of the Texas Finance Code (which
regulates certain revolving loan accounts and revolving tri-party accounts) apply to this Note. To the extent that Chapter 303 of the Texas Finance Code is applicable to this Note, the “weekly ceiling” specified in such article is the
applicable ceiling; provided that, if any applicable law permits greater interest, the law permitting the greatest interest shall apply. 

12. Governing Law, Venue. This Note is being executed and delivered, and is intended to be performed in the State of Texas. Except to
the extent that the laws of the United States of America may apply to the terms hereof, the substantive laws of the State of Texas shall govern the validity, construction, enforcement and interpretation of this Note. In the event of a dispute
involving this Note or any other instruments executed in connection herewith, the undersigned irrevocably agrees that venue for such dispute shall lie in any court of competent jurisdiction in Bexar County, Texas. 

13. Purpose of Loan. Borrower agrees that no advances under this Note shall be used for personal, family or household purposes, and that
all advances hereunder shall be used solely for business, commercial, investment, or other similar purposes. 
 14. Captions. The
captions in this Note are inserted for convenience only and are not to be used to limit the terms herein. 
 15. Renewal. This Note is
given in renewal, extension and increase, but not extinguishment, of all amounts left owing and unpaid on that certain Revolving Promissory Note dated March 2, 2011, executed and delivered by Borrower, formerly known as OYO Geospace
Corporation, and payable to the order of Lender, formerly known as The Frost National Bank, in the original face amount of $25,000,000.00.

(including any Additional Lender, if applicable) shall hold its Applicable Percentage of the outstanding Loans (and participation interests) after giving effect to the increase in the Aggregate Elected Commitment Amounts (and the resulting

such Elected Commitment Increase Certificate or Additional Lender Certificate and record the information contained therein in the Register required to be maintained by the Administrative Agent pursuant to Section 12.04(b)(iv). No increase in
the Aggregate Elected Commitment Amounts shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 2.06(c)(iv).

the Aggregate Elected Commitment Amounts pursuant to this Section 2.06(c), (A) each Lender’s Maximum Credit Amount shall be automatically deemed amended to the extent necessary so that each such Lender’s Applicable Percentage
equals the percentage of the Aggregate Elected Commitment Amounts represented by such Lender’s Elected Commitment, in each case after giving effect to such increase, and (B) Annex I to this Agreement shall be deemed amended to reflect the
Elected Commitment of each Lender (including any Additional Lender) as thereby increased, any changes in the Lenders’ Maximum Credit Amounts pursuant to the foregoing clause (A), and any resulting changes in the Lenders’ Applicable

ratably among the Lenders in accordance with each Lender’s Applicable Percentage. 

     (viii)      Upon any
redetermination or other adjustment in the Borrowing Base pursuant to the Credit Agreement that would otherwise result in the Borrowing Base becoming less than the Aggregate Elected Commitment Amounts, the Aggregate Elected Commitment Amounts shall
be automatically reduced (ratably among the Lenders in accordance with each Lender’s Applicable Percentage) so that they equal such redetermined Borrowing Base (and Annex I shall be deemed amended to reflect such amendments to each
Lender’s Elected Commitment and the Aggregate Elected Commitment Amounts).

effective as of the Subject Acquisition Closing Date, Annex I to the Credit Agreement shall be automatically replaced in its entirety with Annex I-A attached hereto (without any further action required by any party) and Annex I-A
attached hereto shall be deemed to be attached as Annex I to the Credit Agreement. After giving effect to this Section 7 and any Borrowings made on the Subject Acquisition Closing Date, (a) each Lender who holds Loans in an

Credit Agreement as amended hereby, to the same extent as if such New Lender were an original signatory thereto. Each New Lender hereby appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such
powers and discretion under the Credit Agreement as amended hereby as are delegated to the Administrative Agent by the terms thereof, together with such powers and discretion as are reasonably incidental thereto. Each New Lender represents and

appropriate to make its own credit analysis and decision to enter into this Sixth Amendment and to become a Lender on the basis of which it has made such analysis and decision independently and without reliance on the Administrative Agent or any
other Lender, and (c) from and after the Sixth Amendment Effective Date, it shall be a party to and be bound by the provisions of the Credit Agreement as amended hereby and the other Loan Documents and have the rights and obligations of a
Lender thereunder. If the Subject Acquisition Closing Date does not occur, and the conditions set forth in Section 5 hereof are not satisfied, in each case, on or prior to October 31, 2013, any New Lender with a Maximum Credit
Amount of $0.00 shall automatically cease to be a Lender for all purposes under the Credit Agreement and the other Loan Documents as of November 1, 2013. 

Section 9.     Representations and Warranties; Etc. Each Loan Party hereby affirms:
(a) that as of the date hereof, all of the representations and warranties contained in each Loan Document to which such Loan Party is a party are true and correct in all material respects as though made on and as of the date hereof (unless made
as of a specific earlier date, in which case, was true as of such date and except to the extent that any such representation and warranty is qualified by materiality, in which case such representation and warranty shall continue to be true and
correct in all respects), (b) no Defaults exist under the Loan Documents or will, after giving effect to this Sixth Amendment, exist under the Loan Documents and (c) no Material Adverse Effect has occurred. 

Section 10.     Miscellaneous. 

10.1     Confirmation and Effect. The provisions of the Credit Agreement (as amended by this Sixth
Amendment) shall remain in full force and effect in accordance with its terms following the effectiveness of this Sixth Amendment. Each reference in the Credit Agreement to “this Agreement”, “hereunder”, “hereof’,
“herein”, or words of like import shall mean and be a reference to the Credit Agreement as amended hereby, and each reference to the Credit Agreement in any other document, instrument or agreement executed and/or delivered in connection

any number of separate counterparts, and all of such counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of this Sixth Amendment by facsimile or electronic (e.g. pdf) transmission shall be effective as
delivery of a manually executed original counterpart hereof. 
 10.4     No Oral Agreement.
THIS WRITTEN SIXTH AMENDMENT, THE CREDIT AGREEMENT AND THE OTHER LOAN
DOCUMENTS EXECUTED IN CONNECTION HEREWITH AND THEREWITH REPRESENT THE FINAL
AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE

contemplated hereby, including, without limitation, the reasonable fees and disbursements of counsel to the Administrative Agent. 

10.7     Severability. Any provision of this Sixth Amendment which is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction. 
 10.8     Successors
and Assigns. This Sixth Amendment shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.
