Section 1 — Registrant’s Business and Operations

Item 1.01. Entry into a Material Definitive Agreement .

Entry into Merger Agreement

On October 8, 2014, TGC Industries, Inc., a Texas corporation (the “ Company ”), Dawson Geophysical Company, a Texas corporation (“ Dawson ”), and Riptide Acquisition Corp., a Texas corporation and a wholly owned subsidiary of the Company (“ Merger Sub ”), entered into an Agreement and Plan of Merger (the “ Merger Agreement ”), which provides for the merger of Merger Sub with and into Dawson, with Dawson continuing after the merger as the surviving entity and a wholly owned subsidiary of the Company (the “ Merger ”).

Under the terms of the Merger Agreement, at the effective time of the Merger (the “ Effective Time ”) the Company will amend its certificate of formation to change its name to “Dawson Geophysical Company” (the “ Name Change ”). Immediately prior to the Effective Time, the Company will effect a reverse stock split with respect to its common stock, par value $0.01 per share (“ TGC Common Stock ”), on a one-for-three ratio (the “ Reverse Stock Split ”) to reduce the total number of shares of TGC Common Stock outstanding from approximately 22,001,125 to approximately 7,333,708. After giving effect to the Reverse Stock Split, in connection with the Merger each issued and outstanding share of common stock, par value $0.33-1/3 per share of Dawson (the “ Dawson Common Stock ”) (other than shares of Dawson Common Stock owned by the Company, Merger Sub or Dawson or any wholly owned subsidiary of the Company) will be automatically converted into the right to receive 1.760 shares of the Company split-effected Common Stock (the “ Exchange Ratio ”).

Except as otherwise set forth in the Merger Agreement, Dawson stock options will, to the extent such options are not exercised prior to the Effective Time, be converted into and become, respectively, stock option awards based on or comprised of TGC Common Stock, in each case on terms substantially identical to those in effect immediately prior to the Effective Time, and as adjusted by the Exchange Ratio. Except for certain restricted stock and restricted stock unit awards subject to applicable employment agreements or any newly issued awards that do not provide for such restricted stock or restricted stock unit awards to vest upon the Effective Time, to the extent Dawson restricted stock or restricted stock unit awards are outstanding immediately prior to the Effective Time, such awards will be treated as being vested, the shares of Dawson Common Stock that relate to such awards will be treated as being issued and outstanding, and such shares of Dawson Common Stock will be converted to shares of TGC Common Stock pursuant into the preceding paragraph.

The respective Boards of Directors of the Company, Merger Sub and Dawson have approved the Merger Agreement. The Board of Directors of the Company has recommended that the Company’s shareholders approve (1) the issuance of shares of TGC Common Stock to the shareholders of Dawson and (2) amendments to the Company’s certificate of formation to effect the Name Change and the Reverse Stock Split in accordance with the Merger Agreement. The Board of Directors of Dawson has recommended that Dawson shareholders approve the Merger Agreement.

It is expected that the Merger will qualify as a tax-free reorganization for U.S. federal income tax purposes, so that, in general, none of the Company, Merger Sub, Dawson or any of Dawson’s shareholders will recognize any gain or loss in the transaction, except that Dawson shareholders will generally recognize gain or loss with respect to cash received in lieu of fractional shares of TGC Common Stock.

Completion of the Merger is subject to certain customary conditions, including, among other things:

· the approval of the Merger Agreement by the holders of at least 66.67% of the outstanding shares of Dawson Common Stock;

· the approval of the amendments to the Company’s certificate of formation to effect the Name Change and the Reverse Stock Split by the holders of at least 66.67% of the outstanding shares of TGC Common Stock;

· approval of the issuance of shares of TGC Common Stock in the Merger by the holders of at least a majority of the shares of TGC Common Stock present and voting at a special meeting of the Company’s shareholders called to approve the share issuance;

· the expiration or early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976;

· the effectiveness of a registration statement on Form S-4 that will be filed by the Company for the issuance of shares of TGC Common Stock in the Merger and the authorization of the listing of those shares on the Nasdaq Stock Market;

· certain officers of the Company and Dawson having entered into indemnification agreements with the Company effective as of the Effective Time;

· receipt by the Company and Dawson of certain third party consents; and

· the absence of a Material Adverse Effect (as defined in the Merger Agreement) with respect to either the Company’s or Dawson’s respective businesses.

The parties have made customary representations and warranties and agreed to customary covenants in the Merger Agreement. In addition, the Company and Dawson have each agreed to certain pre-closing covenants in the Merger Agreement, including, among other things, covenants that each of the Company and Dawson will, and each will cause its subsidiaries to, during the period between the date of the Merger Agreement and the Effective Time, conduct its business only in the ordinary course of business consistent with past practice, and that each of the Company and Dawson will not engage in certain types of transactions without the consent of the other during such period.

Except as set forth in the Merger Agreement, the Company and Dawson have also agreed not to solicit, initiate, approve, endorse, recommend or encourage, or take any other action designed to, or which would reasonably be expected to, facilitate, any inquiry or the making or announcement of any proposal or offer that constitutes, or that would reasonably be expected to lead to, an Acquisition Proposal (as defined in the Merger Agreement).

The Merger Agreement also provides for certain termination rights for both the Company and Dawson, and further provides that upon any termination of the Merger Agreement under certain circumstances relating to any third party takeover proposal, the party to whom the takeover proposal relates will be obligated to pay the other party, depending on the circumstances, a termination fee of $2.0 million, and may also, under certain circumstances, be required to reimburse the other party for its third party costs and expenses in connection with the proposed Merger, up to a maximum of $1.5 million.

Pursuant to the Merger Agreement, the combined company has agreed to take all necessary actions to cause, as of the Effective Time, its Board of Directors to include Stephen C. Jumper, Craig W. Cooper, Dr. Gary M. Hoover, Ted R. North and Mark A. Vander Ploeg, each of whom is currently a director of Dawson (each a “ Designated Director ”). Wayne A. Whitener, William J. Barrett and Dr. Allen T. McInnes, each of whom is currently a director of the Company (the “ Remaining Directors ”), will continue to serve as directors of the combined company after the Merger, and all other current directors of the Company and Dawson will resign from such positions as of the Effective Time. Pursuant to the Merger Agreement, the combined company will take all necessary action to cause each of the Remaining Directors and the Designated Directors to be nominated for continuing election to the board of directors of the combined company for three years following the Effective Time, other than Mr. Barrett, who will be nominated to serve on the board of directors of the combined company for one year following the Effective Time.

The Company entered into employment agreements, subject to the consummation of the transactions and effective as of the Effective Time, with each of Stephen C. Jumper, Dawson’s President and Chief Executive Officer, to become the Chairman, President and Chief Executive Officer of the combined company, Wayne A. Whitener, the Company’s current President and Chief Executive Officer, to become the Vice Chairman of the combined company, C. Ray Tobias, Dawson’s current Executive Vice President and Chief Operating Officer, to serve in the same capacity for the combined company, James K. Brata, the Company’s current Executive Vice President and Chief Financial Officer, to serve in the same capacity for the combined company, Christina W. Hagan, Dawson’s current Executive Vice President, Chief Financial Officer and Secretary, to become the Executive Vice President, Chief Accounting Officer and Secretary of the combined company, James W. Thomas, Dawson’s current Executive Vice President and Chief Technology Officer, to serve in the same capacity for the combined company, and Daniel G. Winn, the Company’s current Executive Vice President, to become Senior Vice President of the combined company (each, individually, an “ Executive ,” and collectively, all such officers of the combined company, the “ Executives ”). Copies of the employment agreements executed by Mr. Whitener, Mr. Brata, Mr. Winn, Mr. Jumper, Mr. Tobias, Ms. Hagan and Mr. Thomas are filed as Exhibits 10.2, 10.3, 10.4, 10.5, 10.6, 10.7 and 10.8, respectively.

Each of the Designated Directors, the Remaining Directors and the Executive Officers will enter into an indemnification agreement with the combined company in substantially the same form as Dawson has entered into with certain of its current officers and directors, and such form is filed as Exhibit 10.1 to this Current Report on Form 8-K.

In connection with the Merger Agreement, certain officers and directors of the Company who own, in the aggregate, 28.89% of the currently outstanding shares of TGC Common Stock, have entered or agreed to enter into voting agreements with Dawson (the “ TGC Shareholder Voting Agreements ”) in the form filed as Exhibit 99.1 to this Current Report on Form 8-K. Under the TGC Shareholder Voting Agreements, those officers and directors have agreed, among other things, (1) to vote their shares of TGC Common Stock in favor of (A) the issuance of shares of TGC Common Stock in connection with the Merger, and (B) the amendments to the certificate of formation of the Company to effect the Name Change and the Reverse Stock Split, in each case at the special meeting of the Company’s shareholders to be held to vote on the share issuance and amendments to the Company’s certificate of formation and (2) not to sell, transfer or gift any of their shares of TGC Common Stock prior to the consummation of the Merger, except under limited circumstances.

Also in connection with the Merger Agreement, certain officers and directors of Dawson who own, in the aggregate, 2.40% of the currently outstanding shares of Dawson Common Stock, have entered into a voting agreement with the Company (the “ Dawson Shareholder Voting Agreement ”) in the form filed as Exhibit 99.2 to this Current Report on Form 8-K. Under the Dawson Shareholder Voting Agreement, those

officers and directors have agreed, among other things, (1) to vote their shares of Dawson Common Stock in favor of adoption of the Merger Agreement at the special meeting of Dawson shareholders to be held to vote on the proposed transaction and (2) not to sell, transfer or gift any of their shares of Dawson Common Stock prior to the consummation of the Merger, except under limited circumstances.

The foregoing summary of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement attached as Exhibit 2.1 to this Current Report on Form 8-K, which is incorporated herein by reference. The foregoing summary of the TGC Shareholder Voting Agreements and the Dawson Shareholder Voting Agreement, and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the TGC Shareholder Voting Agreements and the Dawson Shareholder Voting Agreement, the forms of which are filed as Exhibits 99.1 and 99.2, respectively, to this Current Report on Form 8-K, and are each incorporated herein by reference.

The Merger Agreement has been included to provide security holders with information regarding its terms. It is not intended to provide any other factual information about the Company, Dawson or their respective subsidiaries or affiliates. The representations, warranties and covenants contained in the Merger Agreement were made solely for purposes of the agreement and as of specific dates, were solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to security holders. Security holders are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company or Dawson. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s or Dawson’s public disclosures.

Further, if, during the term of the Employment Agreement, the Executive’s employment is terminated by the Company without Cause or by the Executive for Good Reason (as each term is defined in the Employment Agreement): (i) the Executive will receive severance payments in an amount equal to the continuation of the Executive’s then-current base salary for the remainder of the term of the Employment Agreement, payable in equal bi-weekly payments in accordance with the Company’s payroll practices, (ii) all award agreements in effect between the Company and the Executive under any equity compensation plan maintained by the Company will become automatically fully vested and exercisable, (iii) the Executive will be entitled to a lump sum payment equal to the cost to the Executive under COBRA to extend his or her then-current group health plan benefits for 18 months following the date of termination, (iv) the Executive will be entitled to a lump sum payment equal to the prorated amount of the bonus, if any, the Executive was eligible to earn pursuant to the Company’s annual incentive plan or similar arrangement, during the calendar year or fiscal year, as applicable, of his or her termination and (v) if the Company was providing the Executive with an automobile, the Executive may, for ten dollars ($10) of consideration paid to the Company, cause the Company to (a) transfer the title of such automobile to the Executive, if such automobile is owned by the Company, or (b) assign the Executive the Company’s right, title and interest in such automobile’s lease, if such automobile is leased by the Company.

In addition, the Employment Agreements contain customary provisions relating to confidentiality, non-solicitation, non-competition and non-disparagement.

Barrett, Edward L. Flynn, Herbert M. Gardner, Stephanie P. Hurtt and Dr. Allen T. McInnes (collectively, the “ Non-employee Directors ”) on July 31, 2014, in each case in substantially the form attached hereto as Exhibit 10.9. The Amendments extend the exercise period of such option award following such Non-employee Director’s termination of service on the Company’s Board of Directors (a “ Termination of Service ”).

C. Voting Agreements . Concurrently with the execution of this Agreement, or as soon as practicable after the date hereof, and as a condition and inducement to Parent’s willingness to enter into this Agreement, certain officers and directors of the Company (the “ Company Voting Shareholders ”), who beneficially own, in the aggregate, 2.40% of the outstanding shares of Company Common Stock as of the date hereof, have each executed and delivered to Parent a voting agreement in the form attached hereto as Exhibit A (each, a “ Company Shareholder Voting Agreement ”), obligating each such signatory to, among other things, vote in favor of the approval of this Agreement and the transactions contemplated hereby, upon the terms and subject to the conditions set forth therein. Concurrently with the execution of this Agreement, and as a condition and inducement to the Company’s willingness to enter into this Agreement, certain officers and directors of Parent (the “ Parent Voting Shareholders ”), who beneficially own, in the aggregate, 28.89% of the outstanding shares of Parent Common Stock as of the date hereof, have each executed and delivered to the Company a voting agreement in the form attached hereto as Exhibit B (the “ Parent Shareholder Voting Agreement ”), obligating each such signatory to, among other things, vote in favor of the approval of the issuance at the Effective Time of Parent Common Stock to the shareholders of the Company, upon the terms and subject to the conditions set forth therein.

(d) Conversion of Merger Sub Common Stock . At the Effective Time, each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $0.33 1/3, of the Surviving Entity.

(e) Treatment of Company Equity Awards .

(i) All options to acquire shares of Company Common Stock and other awards (collectively, “ Company Equity Awards ”) made under the Company’s stock plans (collectively, the “ Company Stock Plans ”) prior to the Effective Time, which are outstanding immediately prior to the Effective Time, are identified in Section 4.1(e) of the Company Disclosure Letter.

(ii) In the event a Company Equity Award constitutes a grant of restricted stock or restricted stock units and to the extent such award is vested immediately prior to the Effective Time (“ Company Vested Stock Based Award ”) (it being understood that any such award that vests pursuant to its terms as of the Effective Time shall, for purposes of this Agreement, be deemed to be vested immediately prior to the Effective Time), the holder of such Company Vested Stock Based Award shall receive the number of shares of Company Common Stock subject to such Company Vested Stock Based Award in accordance with the terms and conditions of the applicable Company Stock Plan, including any terms and conditions regarding any Taxes required by Applicable Law to be withheld, if any, with respect to the vesting of such Company Vested Stock Based Award. In the event a Company Equity Award constitutes a grant of restricted stock or restricted stock units and to the extent such award is, for purposes of this Agreement, unvested and outstanding immediately prior to the Effective Time (“ Company Unvested Stock Based Award ”), such Company Unvested Stock Based Award shall be continued and

assumed by Parent as of the Effective Time pursuant to its terms (such awards are referred to herein as the “ Rollover Stock Based Awards ”); provided , however , that Parent Common Stock shall replace the shares of Company Common Stock subject to such awards pursuant to this Agreement.

(iii) In the event a Company Equity Award constitutes a stock option grant (“ Company Stock Option Award ”) and to the extent such award is outstanding and unexercised as of such time that is immediately prior to the Effective Time, such Company Stock Option Awards shall be continued and assumed by Parent as of the Effective Time pursuant to their terms (such awards are referred to herein as the “ Rollover Stock Option Awards ” and, together with the Rollover Stock Based Awards, the “ Rollover Awards ”); provided , however , that Parent Common Stock shall replace the shares of Company Common Stock subject to such awards pursuant to this Agreement and the exercise price, if any, for such awards, if any, shall be adjusted as provided pursuant to this Agreement. For the avoidance of doubt, to the extent the exercise of any such Company Stock Option Award becomes effective after the date hereof and prior to such time that is immediately prior the Effective Time, the holder of such Company Stock Option Award shall receive the number of shares of Company Common Stock subject to such Company Stock Option Award (to the extent exercised) in accordance with the terms and conditions of the applicable Company Stock Plan, including any terms and conditions regarding the payment of the exercise price and any Taxes required by Applicable Law to be withheld, if any, with respect to the exercise of such Company Stock Option Award.

(iv) The assumption of Rollover Awards shall be made pursuant to this Section 4.1(e) , so that at the Effective Time, the applicable Company Stock Plans shall be assumed by Parent (with such adjustments thereto as may be required to reflect the Merger, including the substitution of Parent Common Stock for Company Common Stock thereunder) and the Rollover Awards shall be assumed and adjusted by Parent, subject to the same terms and conditions as set forth in the applicable Company Stock Plans and the applicable award agreements entered into pursuant thereto; provided , however , that for periods beginning immediately following the Effective Time, (A) the number of shares of Parent Common Stock subject to any such Company Stock Plan shall be the number of shares of Company Common Stock subject to such Company Stock Plan immediately prior to the Effective Time multiplied by the Exchange Ratio (after taking into account the transactions contemplated in the first sentence of Section 4.1(e)(ii) ) (B) each Rollover Award shall only relate to such whole number of shares of Parent Common Stock equal to the product (rounded down to the nearest whole share) of the number of shares of Company Common Stock subject to such Rollover Award immediately prior to the Effective Time multiplied by the Exchange Ratio, and, if applicable, (C) the exercise price per share of Parent Common Stock shall be an amount equal to the exercise price per share of Company Common Stock subject to such Rollover Award in effect immediately prior to the Effective Time divided by the Exchange Ratio (the price per share, as so determined, being rounded up to the nearest whole cent); provided , that in no event shall the exercise price per share be less than the par value of Parent Common Stock. For the avoidance of doubt, any payment or exercise in respect of a

Rollover Award shall be made in accordance with the terms and conditions of the applicable Company Stock Plan, including any terms and conditions regarding the payment of the exercise price, if applicable, and any Taxes required by Applicable Law to be withheld, if any, with respect to the payment or exercise of such Rollover Award. The adjustments provided in this paragraph with respect to any Rollover Stock Option Awards shall be and are intended to be effective in a manner which is consistent with Section 424(a) of the Code and the Treasury Regulations thereunder, and, to the extent applicable, Section 409A of the Code and the Treasury Regulations thereunder.

(v) Except as otherwise provided herein or as set forth in Section 4.1(e)(v) of the Company Disclosure Letter, from and after the period that begins as of the date of this Agreement, the Company and its Subsidiaries shall take no action to provide for the extension of the term or exercise period with respect to any Company Equity Award (unless such extension is required under such Company Equity Awards or any applicable employment or change in control agreement pursuant to any terms thereunder that are in effect as of the date of this Agreement). To the extent such extension is required under the terms of such Company Equity Awards (or any applicable employment or change in control agreement) or as set forth in Section 4.1(e)(v) of the Company Disclosure Letter, the Company shall, prior to the Effective Time, take all actions (if any) as may be required to cause such extension to occur.

(vi) Promptly following the Closing Date, Parent shall file with the Securities and Exchange Commission (the “ SEC ”) a Registration Statement on Form S-8 (or any successor form) covering the shares of Parent Common Stock issuable upon exercise or vesting of the Company Equity Awards, and shall cause such registration statement to remain effective for as long as there are outstanding any such Company Equity Awards. Except as otherwise specifically provided by this Section 4.1(e) , the terms of the Company Equity Awards and the relevant Company Stock Plans, as in effect on the Effective Time, shall remain in full force and effect with respect to the Company Equity Awards after giving effect to the Merger and the assumptions by Parent as set forth above. As soon as practicable following the Effective Time, Parent shall deliver to the holders of Rollover Awards appropriate notices stating that such Rollover Awards and such agreements shall have been assumed by Parent and shall continue in effect on the same terms and conditions (subject to the adjustments required by this Section 4.1(e) ).

(vii) Nothing in this Section 4.1(e) is intended to release any employee or service provider to the Company from any provisions relating to any non-competition, non-solicitation, or confidentiality provisions (or similar provisions) of any Company Equity Award and any associated damages or forfeitures (the “ Equity Award Restrictive Covenants ”), which shall survive the Effective Time. The Company shall take such action as may be necessary to ensure the survival of the Equity Award Restrictive Covenants and the succession of Parent to the benefits of the Equity Award Restrictive Covenants.

Section 4.2 Exchange of Certificates Representing Company Common Stock .

(a) Exchange Fund . As of the Effective Time, Parent shall appoint a commercial bank or trust company reasonably satisfactory to the Company to act as exchange agent hereunder for the purpose of exchanging Certificates and Book Entry Shares (the “ Exchange Agent ”). Parent shall deposit, or cause to be deposited, with the Exchange Agent, in trust for the benefit of the holders of shares of Company Common Stock, the number of shares of Parent Common Stock for exchange in accordance with this Article IV, plus the additional cash amounts sufficient to make payments in lieu of fractional shares of Parent Common Stock in accordance with Section 4.2(e) (such cash and shares of Parent Common Stock, together with any dividends or distributions with respect thereto in accordance with Section 4.2(c) , being hereinafter referred to as the “ Exchange Fund ”). Parent shall deposit such shares of Parent Common Stock with the Exchange Agent by delivering to the Exchange Agent certificates representing, or providing to the Exchange Agent an uncertificated book-entry for, such shares.

(b) Exchange Procedures . Promptly after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of one or more shares of Company Common Stock as of the Effective Time: (i) a letter of transmittal (the “ Letter of Transmittal ”), which shall specify that delivery shall be effected, and risk of loss and title to the shares of Company Common Stock shall pass, only upon delivery of the corresponding Certificates to the Exchange Agent or receipt by the Exchange Agent of an “agent’s message” with respect to Book Entry Shares and shall be in such form and have such other provisions as Parent and the Company may reasonably specify, and (ii) instructions for use in effecting the surrender of such Certificates or Book Entry Shares in exchange for the Merger Consideration and any unpaid dividends and distributions on shares of Parent Common Stock in accordance with Section 4.2(c) . Upon surrender of a Certificate or Book Entry Shares for cancellation to the Exchange Agent together with such Letter of Transmittal, duly executed and completed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate or Book Entry Shares shall be entitled to receive in exchange therefor (x) one or more shares of Parent Common Stock which shall be in uncertificated book-entry form unless a physical certificate is requested (in accordance with Section 4.2(i) ) and which shall represent, in the aggregate, that number of whole shares of Parent Common Stock that such holder has the right to receive pursuant to Section 4.1(a) and (y) a check representing cash in lieu of fractional shares, if any, pursuant to Section 4.2(e) and unpaid dividends and distributions, if any, which such holder has the right to receive pursuant to the provisions of this Article IV, after giving effect to any required withholding Tax, and any Certificate or Book Entry Shares so surrendered shall forthwith be canceled. No interest will be paid or will accrue on the cash in lieu of fractional shares and unpaid dividends and distributions, if any, payable to holders of Company Common Stock. In the event of a transfer of ownership of Company Common Stock that is not registered in the transfer records of the Company, one or more shares of Parent Common Stock which shall be in uncertificated book-entry form unless a physical certificate is requested (in accordance with Section 4.2(i) ) and which shall represent, in the aggregate, the proper number of shares of Parent Common Stock, together with a check for cash in lieu of fractional shares, if any and unpaid dividends and distributions, if any, which such holder has the right to receive pursuant to the provisions of this Article IV, may be issued to such a transferee if the Certificate

representing such Company Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid.

(e) Each No-Shop Party (i) shall, and shall cause its Subsidiaries to, immediately cease and cause to be terminated and shall cause its and its Subsidiaries’ Representatives to, immediately cease and cause to be terminated, all discussions and negotiations, if any, with any Person conducted heretofore with respect to any Acquisition Proposal in respect of such No-Shop Party and (ii) shall promptly request the return or destruction of all confidential information previously furnished and immediately terminate all physical and electronic dataroom access previously granted to any such Person or its Representatives.

(ii) “ Special Valuation Proposal ” means a Superior Proposal that the No-Shop Party’s Board of Directors determines in good faith, after receipt of advice from a financial advisor of nationally recognized reputation, that, if consummated, would result in such No-Shop Party’s shareholders receiving consideration valued at 115% or more of the consideration to be received by such No-Shop Party’s shareholders pursuant to the transactions contemplated by this Agreement, as such consideration may have then been modified by the Other Party in response to such Acquisition Proposal.

(iii) “ Superior Proposal ” means any bona fide written Acquisition Proposal made by any Person other than the Other Party or its Affiliates, which, if consummated, would result in such Person (or its shareholders) owning, directly or indirectly, at least 80% of the shares of Company Common Stock or Parent Common Stock, as applicable, then outstanding (or of the surviving entity in a merger or the direct or indirect parent of the surviving entity in a merger) or at least 80% of all the assets of the No-Shop Party, which the No-Shop Party’s Board of Directors determines in good faith, after receipt of advice from a financial advisor of nationally recognized reputation and outside counsel, to be (A) more favorable to the shareholders of the No-Shop Party from a financial point of view than the Merger, taking into account all the terms and conditions of such proposal, the Person making such proposal and this Agreement (including any break-up fees, expense reimbursement provisions, conditions to consummation, strategic considerations, legal and regulatory considerations, and any changes to the terms of this Agreement proposed by the Other Party in response to such offer or otherwise pursuant to this Section 7.3 ) and (B) reasonably likely to be completed on the terms proposed, taking into account all financial, legal, regulatory and other aspects of such proposal.

Accordingly, if the Company or Parent fails to pay the amount due pursuant to this Section 9.5 , and, in order to obtain such payment, the other party commences a suit that results in a judgment for a fee payable pursuant to this Section 9.5 , such party shall also reimburse the other party’s costs and expenses (including attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of such fee from the date such payment was required to be made until the date of payment at the prime lending rate prevailing during such period as published in The Wall Street Journal . Any payment to be made under this Section 9.5 shall be made by wire transfer of same-day funds.

(g) Each party agrees that in the event that a termination fee is paid pursuant to Section 9.5(a) or Section 9.5(b) , the payment of such termination fee shall be the sole and exclusive remedy of the party to which such fee is paid, its Subsidiaries and any of its respective shareholders, Affiliates, officers, directors, employees or Representatives (collectively, “ Related Persons ”), and in no event will the party to which such fee is paid or any of its Related Persons be entitled to recover any other money damages or any other remedy based on a claim in law or equity with respect to, (i) any loss suffered as a result of the failure of the Merger to be consummated, (ii) the termination of this Agreement, (iii) any liabilities or obligations arising under this Agreement, or (iv) any Proceedings arising out of or relating to any breach, termination or failure of or under this Agreement, and upon payment to the Company or Parent, as applicable, such other party shall not have any further liability or obligation to the party that paid such termination fee or any of its Related Persons relating to or arising out of this Agreement or the transactions contemplated hereby.

(h) In the event of termination of this Agreement and the abandonment of the Merger pursuant to Section 9.1 through Section 9.4 , this Agreement shall forthwith become null and void and all obligations of the parties hereto and their Related Persons shall terminate, except the obligations of the parties pursuant to this Section 9.5, the last sentence of Section 7.6 , Section 7.10 and Article X; provided , that, except as provided in Section 9.5(g) , nothing herein shall relieve any party from any liability arising out of actual fraud or for any willful and material breach by such party of any of its representations, warranties, covenants or agreements set forth in this Agreement, and all rights and remedies of the nonbreaching party under this Agreement, at law or in equity, shall be preserved. The Confidentiality Agreement shall survive any termination of this Agreement, and the provisions of such Confidentiality Agreement shall apply to all information and material delivered by any party hereunder.

Section 9.6 Extension; Waiver . At any time prior to the Effective Time, each party may by action taken by its Board of Directors (or by any duly authorized committee thereof), to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (b) waive in whole or in part any inaccuracies in the representations and warranties made to such party contained herein or in any document delivered pursuant hereto and (c) waive in whole or in part compliance with any of the agreements or conditions for the benefit of such party contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. Except as provided in this Agreement, no action taken pursuant to this Agreement, including any investigation by or on behalf of any party, or delay or omission in the exercise of any right, power or remedy accruing to any party as a result of any breach or default hereunder by any other party, shall be

deemed to impair any such right, power or remedy, nor will it be deemed to constitute a waiver by the party taking such action of compliance with any representations, warranties, covenants or agreements contained in this Agreement. The waiver by any party hereto of a breach of any provision hereunder shall not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder.

Exhibit 10.1

RESTATED INDEMNIFICATION AGREEMENT

This Restated Indemnification Agreement (this “ Agreement ”) is made and entered into as of [ ], by and between Dawson Geophysical Company, a Texas corporation (formerly known as TGC Industries, Inc.) (the “ Company ”), and (the “ Indemnitee ”).

WHEREAS, qualified persons are reluctant to serve organizations as directors or officers or in other capacities unless they are provided with adequate protection against risks of claims and actions against them arising out of their service to and activities on behalf of such organizations;

WHEREAS, the parties hereto recognize that the legal risks and potential liabilities, and the threat thereof, associated with lawsuits filed against persons serving the Company and/or its subsidiaries, and the resultant substantial time, expense and anxiety spent and endured in defending lawsuits bears no reasonable relationship to the compensation received by such persons, and thus poses a significant deterrent and increased reluctance on the part of experienced and capable individuals to serve the Company and/or its subsidiaries;

WHEREAS, the uncertainties related to obtaining adequate insurance and indemnification have increased the difficulty of attracting and retaining such persons;

WHEREAS, Chapter 8 of the Texas Business Organizations Code (the “ TBOC ”) of the State of Texas, under which law the Company is organized, empowers a corporation organized in Texas to indemnify persons who serve as directors and/or officers of the corporation, or persons who serve at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise;

WHEREAS, the Bylaws of the Company permit indemnification to the fullest extent permitted by applicable law;

WHEREAS, it is reasonable, prudent and necessary for the Company to contractually agree to indemnify such persons to the fullest extent permitted by law, so that such persons will serve or continue to serve the Company and/or its subsidiaries free from undue concern that they will not be adequately indemnified; and

WHEREAS, the Indemnitee is willing to serve, continue to serve and to take on additional service for and on behalf of the Company on the condition that the Indemnitee is indemnified according to the terms of this Agreement;

WHEREAS, this Agreement shall supersede and replace any prior agreement between the Indemnitee and the Company or its predecessors with respect to indemnification and the other matters contained herein, including, but not limited to, that certain Indemnification Agreement dated as of between the Indemnitee and [Dawson Geophysical Company/TGC Industries, Inc.];

NOW, THEREFORE, in consideration of the premises and of the Indemnitee’s agreement to provide services to the Company and/or its subsidiaries and intending to be legally bound hereby, the parties hereto agree as follows:

1. Certain Definitions . For purposes of this Agreement:

(h) “ Indemnifiable Event ” means any event or occurrence related to the fact that the Indemnitee is or was serving as a member of the Board and/or an officer of the Company, or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

(i) “ Indemnitee ” shall have the meaning ascribed to such term in the preamble.

Notwithstanding the foregoing, the term “Special Legal Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing in the State of Texas, would have a conflict of interest in representing either the Company or the Indemnitee in an action to determine the Indemnitee’s rights to indemnification under this Agreement.

(l) “ TBOC ” shall have the meaning ascribed to such term in the recitals.

2. Indemnification Arrangement . In the event the Indemnitee was, is or becomes a party to or witness or other participant in, or is threatened to be made a party to or witness or other participant in, a Proceeding by reason of (or arising in part out of) an Indemnifiable Event, to the fullest extent permitted by the TBOC or other applicable law as the same may exist or be hereinafter amended (by statute or judicial decision) (but in the case of any

such amendment, with respect to matters occurring before such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than said law permitted the Company to provide prior to such amendment), the Company shall, subject to and in accordance with the provisions of Section 6, indemnify and hold harmless the Indemnitee against any and all Expenses of such Proceeding as soon as practicable but in any event no later than (a) in the case of an initial written request for indemnification in connection with a Proceeding, five days after a determination has been made, or is deemed to have been made, that the Indemnitee is entitled to indemnification and (b) in the case of a written request for indemnification made pursuant to Section 5 in connection with a Proceeding for which a determination has been made that the Indemnitee is entitled to indemnification in connection with such Proceeding, five days after such written request.

3. Advancement or Reimbursement of Expenses . The rights of the Indemnitee provided under Section 2 shall include, but not be limited to, the right to be indemnified and to have all Expenses advanced (including the payment of Expenses before final disposition of a Proceeding) in all Proceedings to the fullest extent permitted, or not prohibited, by the TBOC or other applicable law. In addition, to the extent the Indemnitee is, by reason of (or arising in part out of) an Indemnifiable Event, a witness or otherwise participates in any Proceeding at a time when he is not named a defendant or respondent in the Proceeding, he shall be indemnified against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. The Indemnitee shall be advanced Expenses, within five days after any request for such advancement, to the fullest extent permitted, or not prohibited, by Chapter 8 of the TBOC; provided that the Indemnitee has provided to the Company all affirmations, acknowledgments, representations and undertakings that may be required of the Indemnitee by Chapter 8 of the TBOC.

4. No Settlement without Consent . The Company shall not be liable to indemnify the Indemnitee under this Agreement for any amounts paid in settlement of any Proceeding effected without its written consent. The Company shall not settle any action or claim in any manner which would impose any penalty or limitation on the Indemnitee without the Indemnitee’s written consent. Neither the Company nor the Indemnitee will unreasonably withhold or delay their consent to any proposed settlement.

5. Request for Indemnification . To obtain indemnification as herein provided, the Indemnitee shall submit to the Secretary of the Company a written claim or request. Such written claim or request shall contain sufficient information to reasonably inform the Company about the nature and extent of the indemnification or advance sought by the Indemnitee. The Secretary of the Company shall promptly advise the Board of such request.

6. Determination of Request .

(a) Upon written request to the Company by the Indemnitee for indemnification pursuant to this Agreement, a determination, if required by applicable law, with respect to the Indemnitee’s entitlement thereto shall be made in accordance with Section 8.103(a)(1) or (2) of the TBOC; provided, however, that notwithstanding the foregoing, if a Change in Control shall have occurred, such determination shall be made by a Special Legal Counsel selected by the

Board, unless the Indemnitee shall request (at the time the Indemnitee submits the written request for indemnification) that such determination be made in accordance with Section 8.103(a)(1) or (2) of the TBOC.

(b) If entitlement to indemnification is to be determined by a Special Legal Counsel, the Company shall furnish notice to the Indemnitee within ten days after receipt of a claim of or request for indemnification, specifying the identity and address of the Special Legal Counsel and a certification by the Special Legal Counsel that the Special Legal Counsel has reviewed and is in compliance with the requirements to be a Special Legal Counsel. The Indemnitee may, within seven days after receipt of such written notice of selection, deliver to the Company a written objection to such selection. Such objection may be asserted only on the ground that the Special Legal Counsel selected does not meet the requirements of a Special Legal Counsel as defined in this Agreement, and the objection shall set forth with particularity the factual basis for that assertion. If there is an objection to the selection of the Special Legal Counsel, either the Company or the Indemnitee may petition the Court for a determination that the objection is without a reasonable basis and/or for the appointment of a Special Legal Counsel selected by the Court. The Company shall pay any and all reasonable fees and expenses of the Special Legal Counsel incurred in connection with any such determination. If a Change in Control shall have occurred, the Indemnitee shall be presumed (except as otherwise expressly provided in this Agreement) to be entitled to indemnification under this Agreement upon submission of a request to the Company for indemnification, and thereafter the Company shall have the burden of proof in overcoming that presumption in reaching a determination contrary to that presumption. The presumption shall be used by the Special Legal Counsel, or such other person or persons determining entitlement to indemnification, as a basis for a determination of entitlement to indemnification unless the Company provides information sufficient to overcome such presumption by clear and convincing evidence or the investigation, review and analysis of the Special Legal Counsel or such other person or persons convinces him or them by clear and convincing evidence that the presumption should not apply.

(c) The Indemnitee will cooperate with the person or persons making the determination under this Section 6 with respect to the Indemnitee’s entitlement to indemnification under this Agreement, including providing to such person or persons, on reasonable advance request, any documentation or information that is: (i) not privileged or otherwise protected from disclosure; (ii) reasonably available to Indemnitee; and (iii) reasonably necessary to that determination.

(d) Any determination of the Indemnitee’s entitlement to indemnification to be made pursuant to this Section 6 shall be made, and the Indemnitee shall be notified of such determination, not later than 20 days after receipt by the Secretary of the Company of the Indemnitee’s written claim for indemnification; provided, however, that in the case of a determination to be

made by Special Legal Counsel the selection of whom is the subject of an existing objection, such determination, and the Indemnitee’s notification of such determination, shall be made not later than 20 days after the selection of the Special Legal Counsel is finally determined. Notwithstanding anything herein to the contrary, if the person or persons empowered under this Section 6 to determine entitlement to indemnification have not made a determination within the applicable period set forth in this Section 6(d), the Indemnitee shall be deemed to be entitled to indemnification unless the Company establishes that a Disqualifying Event has occurred. Subject to applicable law, determinations of entitlement to indemnification made, or deemed to have been made, in accordance with the provisions of this Section 6, shall be conclusive, final and binding on the parties hereto unless, in the event the Company has previously determined to indemnify the Indemnitee, the Company establishes as provided in the final sentence of this Section 6 that: (i) the Indemnitee misrepresented or failed to disclose a material fact in making the request for indemnification; or (ii) such indemnification is prohibited by applicable law (each event described in subclause (i) or (ii) of this Section 6, a “ Disqualifying Event ”). Notwithstanding the foregoing, the Company may bring an action, in an appropriate court in the State of Texas or any other court of competent jurisdiction, contesting the right of the Indemnitee to receive indemnification hereunder due to the occurrence of a Disqualifying Event; provided, however, that in any such action the Company will have the burden of proving the occurrence of such Disqualifying Event.

7. Effect of Certain Proceedings . The termination of any Proceeding or of any matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of the Indemnitee to indemnification or create a presumption that (a) the Indemnitee did not conduct himself in good faith and in a manner which he reasonably believed, in the case of conduct in his official capacity, to be in the best interests of the Company, or, in all other cases, that at least his conduct was not opposed to the Company’s best interests, or (b) with respect to any criminal Proceeding, that the Indemnitee had reasonable cause to believe that his conduct was unlawful.

8. Expenses of Enforcement of Agreement . The Indemnitee shall be entitled to seek an adjudication to enforce his rights under, or to recover damages for breach of rights created under or pursuant to, this Agreement either, at the Indemnitee’s option, in (a) an appropriate court of the State of Texas or any other court of competent jurisdiction, or (b) an arbitration to be conducted by a single arbitrator, selected by mutual agreement of the Company and the Indemnitee (or, failing such agreement by the then sitting Chief Judge of the United States District Court for the appropriate jurisdiction), pursuant to the commercial arbitration rules of the American Arbitration Association. In the event that the Indemnitee seeks any such judicial adjudication or arbitration award to enforce his rights under, or to recover damages for breach of rights created under or pursuant to, this Agreement, the Indemnitee shall be entitled to recover from the Company, and shall be indemnified by the Company against, any and all Expenses actually and reasonably incurred by him in such judicial adjudication but only if he prevails therein. If it shall be determined in said judicial adjudication that the Indemnitee is entitled to receive part but not all of the indemnification or advancement of Expenses sought, the

Expenses incurred by the Indemnitee in connection with such judicial adjudication shall be reasonably prorated in good faith by counsel for the Indemnitee. Notwithstanding the foregoing, if a Change in Control shall have occurred, the Indemnitee shall be entitled to indemnification under this Section 8 regardless of whether the Indemnitee ultimately prevails in such judicial adjudication.

9. Common Attorney . Notwithstanding the obligation of the Company to indemnify the Indemnitee against Expenses pursuant to Section 2, in the event there is a Proceeding by reason of (or arising in part out of) an Indemnifiable Event against several persons, including the Indemnitee, who have a right of indemnification against the Company with respect to Expenses relating to such Proceeding and who have totally common interests such that their goals are identical and there are no conflicts-of-interest among them, then such group of persons shall, by majority vote of such persons, select a single attorney or law firm to serve as the sole and exclusive legal counsel for all of the members of such group (including the Indemnitee). In the event the Indemnitee acts independently by retaining the legal services of any other attorney or law firm to additionally or separately represent him, all Expenses relating to such independently retained attorney or law firm shall be the sole responsibility of the Indemnitee.

10. Nonexclusive Rights; Subsequent Change in Law . The rights of indemnification and to receive advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which the Indemnitee may at any time be entitled under applicable law, the articles of incorporation of the Company, the Bylaws of the Company, agreement, insurance, arrangement, a vote of shareholders or a resolution of directors, or otherwise. To the extent that a change in the TBOC or other applicable law (whether by statute or judicial decision) permits greater indemnification by agreement than would be afforded currently under the Company’s articles of incorporation or bylaws and this Agreement, it is the intent of the parties hereto that the Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change.

11. D&O Liability Insurance . The Company shall from time to time make a good faith determination whether or not it is practicable for the Company to obtain and maintain a policy or policies of insurance with reputable insurance companies providing the directors and officers of the Company or its subsidiaries or affiliates, with coverage for losses incurred in connection with their services to the Company or its subsidiaries or affiliates or to ensure the Company’s performance of its indemnification obligations under this Agreement. Among other considerations, the Company will weigh the costs of obtaining such insurance coverage against the protection afforded by such coverage. To the extent the Company maintains an insurance policy or policies providing directors’ and/or officers’ liability insurance, the Indemnitee shall be covered by such policy or policies, in accordance with its or their terms, to the maximum extent of the coverage available for any of the Company’s directors and/or officers. The Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that the Indemnitee has otherwise actually received such payment under any bylaws, insurance policy, contract, agreement or otherwise.

12. No Employment Rights . Nothing in this Agreement is intended to create in the Indemnitee any right to continued service as a director and/or officer with the Company.

13. Amendments; Waiver . No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver.

14. Subrogation . In the event of payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee, who shall execute all papers required and shall do everything that may be necessary to secure such rights, including the execution of such documents necessary to enable the Company effectively to bring suit to enforce such rights.

15. Term . This Agreement shall be effective from and after the date hereof, and shall continue until and terminate upon the later of: (a) the sixth anniversary after the Indemnitee has ceased to be a member of the Board and/or an officer of the Company or otherwise hold a position that could give rise to an Indemnifiable Event or (b) the final termination or resolution of all Proceedings with respect to which the Company is indemnifying the Indemnitee against any and all Expenses relating to such Proceeding pursuant to the terms of this Agreement that are commenced prior to such six-year anniversary.

16. Notification and Defense of Claims . The Indemnitee agrees to notify the Company promptly in writing upon being served with any summons, citation, subpoena, complaint, indictment, information, or other document relating to any matter which may be subject to indemnification hereunder, whether civil, criminal, or investigative; provided. however, that the failure of the Indemnitee to give such notice to the Company shall not adversely affect the Indemnitee’s rights under this Agreement except to the extent the Company has been materially prejudiced as a direct result of such failure. Nothing in this Agreement shall constitute a waiver of the Company’s right to seek participation at its own expense in any Proceeding which may give rise to indemnification hereunder.

17. Binding Effect . This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors or assigns (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business and/or assets of the Company), spouses, heirs, executors and personal or legal representatives. This Agreement shall continue in effect regardless of whether the Indemnitee continues to serve as a director and/or officer of the Company.

18. Severability . The provisions of this Agreement shall be severable in the event that any of the provisions hereof (including any provision within a single section, paragraph or sentence) is held by a court of competent jurisdiction to be invalid, void or otherwise unenforceable in any respect, and the validity and enforceability of any such provision in every other respect and of the remaining provisions hereof shall not be in any way impaired and shall remain enforceable to the fullest extent permitted by law. To the fullest extent possible, the provisions of this Agreement shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

19. Governing Law . This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Texas, without giving effect to conflicts of law provisions thereof.

20. Notice . All notices, demands and other communications required or permitted under this Agreement shall be made in writing and shall be deemed to have been duly received upon actual receipt if delivered by hand, against receipt, or mailed, postage prepaid, certified or registered mail, return receipt requested, and addressed to the Company at:

Notwithstanding the terms of this Section 3, the Executive’s employment shall be at all times subject to earlier termination in accordance with Section 6 and the other terms, provisions and conditions set forth in this Agreement.

4. Compensation

6. Termination of Employment

(a) Termination of Employment . The Executive’s employment with the Company may be terminated as follows (it being understood and agreed that a party’s determination not to renew the Term of this Agreement shall not constitute termination under any provision of this Section 6):

(i) Termination by the Company for Cause . The Company may terminate the Executive’s employment for Cause after providing the Executive with written notice of the Company’s intent to terminate the Executive’s employment and the reason(s) therefor. The Executive will have 30 days in which to cure the reason(s) provided by the Company. At the end of such 30-day period, if the Executive has not cured the Cause specified in the written notice as the reason for such termination, then the Executive’s employment with the Company shall terminate as of the date provided in such notice of termination.

(ii) Termination by the Company Without Cause . The Company may, on written notice to the Executive, terminate the Executive’s employment other than

For the avoidance of doubt, the parties agree that the vesting and exercisability (as applicable) of the Covered Awards pursuant to clause (ii) above upon a termination described herein shall, to the extent required to give effect to such clause (ii), constitute an amendment to such Covered Awards and the related Stock Plan with respect to the Executive but no other person.

(v) Return of Company Property . Upon termination of the Executive’s employment with the Company, the Executive (or, in the event of death, the Executive’s estate) shall promptly deliver to the Company all of the Company’s property in the Executive’s possession or under the Executive’s control or related to the Company’s business, including but not limited to any vehicle, keys, records, notes, books, maps, plans, data, memoranda, models, electronically recorded data or software, and any computers, mobile phones and other equipment (including any of the foregoing reflecting or containing any information relating to any assets or projects in which the Company has any direct or indirect interest), and all other Confidential Information (as defined below), and shall retain no copies or duplicates of any such property or Confidential Information.

If a reduction of such Total Payments is necessary, cash severance payments provided for herein shall first be reduced (such reduction to be applied first to the payments otherwise scheduled to occur the earliest), and the non-cash severance benefits provided for herein shall thereafter be reduced (such reduction to be applied first to the benefits otherwise scheduled to occur the earliest).

(a) Assignment of Work Product to the Company .

To the extent any of the Executive’s rights, title or interest to the Work Product cannot be assigned to the Company, the Executive grants and will grant an exclusive, worldwide, transferable, irrevocable, royalty-license (with rights to sublicense without consent of the Executive) to the Company to exploit fully such Work Product.

NEWS RELEASE

DAWSON GEOPHYSICAL AND TGC INDUSTRIES

ANNOUNCE STRATEGIC BUSINESS COMBINATION

Conference Call to be Held on October 9 at 9:00 a.m. ET

MIDLAND, Texas, October 9, 2014 — Dawson Geophysical Company (Dawson) (NASDAQ: DWSN) and TGC Industries, Inc. (TGC) (NASDAQ: TGE) today jointly announced a proposed strategic business combination. Upon consummation of the transaction, current Dawson and TGC shareholders will own approximately 66% and 34% of the combined company, respectively. Closing of the transaction is anticipated during the first calendar quarter of 2015, subject to the approval by holders of 66.67% of the outstanding shares of both TGC and Dawson, as well as certain other closing conditions and regulatory approvals.

The transaction is structured as a tax-free stock-for-stock transaction. Dawson will merge with a TGC subsidiary and become a wholly-owned subsidiary of TGC. TGC will change its name to Dawson Geophysical Company (hereinafter referred to as new Dawson). The new Dawson shares will trade on NASDAQ under the symbol DWSN.

Immediately prior to the transaction, TGC will implement a 1-for-3 reverse stock split. The reverse stock split will provide for a sufficient number of TGC authorized shares to consummate the transaction and adjust the number of post-transaction shares to facilitate trading within reasonable price ranges and volumes on NASDAQ. After giving effect to the TGC reverse stock split, Dawson shareholders will receive 1.76 shares of TGC split-effected common stock for each share of Dawson common stock held at the effective time of the transaction, with cash to be paid in lieu of any fractional shares. For example, at the effective time of the transaction, a TGC shareholder currently owning 100 shares of TGC common stock will own 33 shares of split-effected TGC common stock, while a Dawson shareholder currently owning 100 shares of Dawson common stock will receive 176 shares of TGC split-effected common stock. As a result of the reverse stock split, TGC’s currently outstanding shares will be reduced from approximately 22,001,125 million to 7,333,708 million shares and TGC will issue approximately 14,236,022 million TGC split-effected shares in exchange for approximately 8,065,233 shares held by Dawson shareholders. Based on the above-noted exchange ratio and reverse stock split, at the effective time of the transaction, the implied valuation of the current Dawson shares should be three times the trading price of the TGC shares multiplied by 1.76.

Stephen Jumper, current Chairman, President and Chief Executive Officer of Dawson, will serve as Chairman, President and CEO of new Dawson. Wayne Whitener, current President, CEO and a Director of TGC, will serve as Vice Chairman of the Board and an officer of new Dawson. Ongoing operations will be conducted under the Dawson and Eagle Canada names.

In addition to Messrs. Jumper and Whitener, the Board of Directors of new Dawson will include four members of the current Dawson board - Craig Cooper, Gary Hoover, Ted North and Mark Vander Ploeg - and two members of the current TGC board — William Barrett and Dr. Allen McInnes.

The Dawson and TGC Boards of Directors have approved the transaction, and directors and certain officers representing approximately 28.89% of outstanding TGC shares and approximately 2.40% of outstanding Dawson shares have agreed to vote in favor of the transaction. The Boards of Directors of both companies have recommended to their respective shareholders that they vote in favor of the transaction.

Transaction Highlights:

· Expanded geographical presence and expertise to better serve client base

· Combined strong balance sheet will provide increased operational and financial flexibility

· Complementary equipment bases increase operational efficiencies and logistics

· Improved processes and increased efficiencies lead to lower cost structure and increased revenue

· Increased level of services and reduced outsourcing

· Increased channel count for improved efficiency, higher resolution imaging and to meet increased channel count requirements

· Expanded client base and order book will increase crew utilization rates

Stephen Jumper, Chairman, President and Chief Executive Officer of Dawson, said, “This is an exciting time for our companies as we work together to combine our complementary resources and create a best-of-breed company. The combination of Dawson and TGC results in a stronger company that will better serve our valued clients, shareholders and employees. The demand on our technology has been to produce cost-effective, high-resolution images in a shorter cycle time. The combination of Dawson and TGC improves our ability to meet that demand with an expanded equipment base, logistics advantages, and improved services and expertise. Collectively, our resources are further positioned to increase utilization rates, reduce costs and provide multiple avenues of growth for the combined company.”

Wayne Whitener, President and Chief Executive Officer of TGC, said, “We are extremely pleased to join forces with the Dawson Geophysical team.

All participants will be in listen-only mode. (Operator Instructions) After today's presentation, there will be an opportunity to ask questions. (Operator Instructions) Please note this event is being recorded. Now I would like to turn the conference over to Steve Jumper. Mr. Jumper, please go ahead. Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Well, good morning, and welcome to the Dawson Geophysical/TGC Industries transaction conference call. As Keith said, my name is Steve Jumper, Chairman, President, and CEO of Dawson. I'm pleased to have with me Wayne Whitener, President, CEO, and Director of TGC Industries. This morning's call is scheduled for approximately 60 minutes. Following my remarks, I will turn control over the call to Wayne. At the conclusion of Wayne's comments, we will open the call for questions. As in our past calls, we will not be providing guidance. I will note that there are accompanying slides that can be viewed on Company websites: www.dawson3d.com, and www.tgcseismic.com. As is our normal protocol, this presentation will include forward-looking statements. I refer to our normal disclaimers concerning such matters, which are included in our slide deck for today's call. Moving to page 3 of the slide show: today Dawson Geophysical Company and TGC Industries, Inc. jointly announced a proposed strategic business combination. Upon consummation of the transaction, current Dawson and TGC shareholders will own approximately 66% and 34% of the combined Company, respectively. Closing of the transaction is anticipated during the first calendar quarter of 2015, subject to the approval by holders of 66.67% of the outstanding shares of both TGC and Dawson, as well as certain other closing conditions and regulatory approvals. The transaction is structured as a tax-free stock-for-stock transaction. Dawson will merge with a TGC subsidiary and become a wholly-owned subsidiary of TGC. TGC will then change its name to Dawson Geophysical, and the new Dawson shares will trade on NASDAQ under the symbol DWSN. Moving on to page 4: as part of the transaction, I, Steve Jumper, the current President, Chairman, and CEO of Dawson, will serve as Chairman, President, and CEO of the new Dawson. And Wayne Whitener, current President, CEO, and Director of TGC, will serve as Vice Chairman and an Officer of the new Dawson. The Board of Directors of the new Dawson will include four additional members of the current Dawson Board: Craig Cooper, Lead Director; Gary Hoover; Ted North; Mark Vander Ploeg; and two additional members of the current TGC Board, William Barrett and Allen McInnes.

'Thomson Reuters' and the Thomson Reuters logo are registered trademarks of Thomson Reuters and its affiliated companies. Moving on to 5 -- excuse me, 6. Moving on to 6: immediately prior to the transaction, TGC will implement a 1-for-3 reverse stock split. The reverse stock split will provide for a sufficient number of TGC authorized shares to consummate the transaction and adjust the number of post-transaction shares to facilitate trading within reasonable price ranges and volumes on NASDAQ. After giving effect to the TGC reverse stock split, Dawson shareholders will receive 1.76 shares of TGC spliteffected common stock for each share of Dawson common stock held at the effective time of the transaction, with cash to be paid in lieu of any fractional shares. For example, at the effective time of the transaction, a TGC shareholder currently owning 100 shares of TGC common stock will own 33 shares of split-effected TGC common stock; while a Dawson shareholder currently owning 100 shares of Dawson common stock will receive 176 shares of TGC split-effected common stock. As a result of the reverse stock split, TGC's currently outstanding shares will be reduced from approximately 22 million to 7.3 million shares, and then TGC will issue approximately 14.2 million TGC split-effected shares in exchange for approximately 8 million shares held by Dawson shareholders. Based on the above-noted exchange ratio and reverse stock split, at the effective time of the transaction, the applied valuation of the current shares should be 3 times the trading price of the TGC shares multiplied by 1.76. The Dawson and TGC Boards of Directors have approved the transaction, and Directors and certain Officers representing approximately 28.89% of TGC's outstanding shares and approximately 2.4% of Dawson's outstanding shares have agreed to vote in favor of the transaction. The Boards of the new Dawson have recommended to the respective shareholders that they vote in favor of the business combination. Moving on to 7. Well, today is an exciting day for both Dawson Geophysical and TGC Industries and their family of Companies: Tidelands Geophysical, Eagle Canada, Dawson Seismic Services. In March of 2011 the two Companies entered into a transaction which was subsequently terminated in October of 2011. Despite delays in receiving regulatory approvals and the fact that each Company's stock began to trade outside negotiated collar and the failure to meet certain required shareholder votes, the transaction received overwhelming shareholder support from both shareholder bases. We believe now, as we believed in 2011, a combination of Dawson and TGC results in a company which the sum is greater than the parts. Both management teams and Boards of Directors believe the improved platform of shared people, services, and equipment provides a better opportunity to serve our clients, shareholders, and employees. We are confident our collective resources, combined client base, and order book will aid to relieve current pressure on crew and channel utilization, lower cost, and improve growth opportunities. We are staying focused on the message -- and the message that existed in 2011 is the same message that we are seeing today. The demand on our technology in the past and continued today is to produce cost-effective, high-resolution seismic images and a shorter cycle time. The combination of Dawson and TGC Industries improves our ability to meet that demand with an expanded equipment base, logistics advantages, increased services, additional expertise. That was the case in 2011, and it's the same case today. Moving on to -- again, staying on 7: the new Dawson further expands our logistical advantages, providing us greater opportunities to meet client demands in various regions. The geographic diversity and accompanying logistical advantages should enable us to strategically deploy crews on a regional basis more consistently. We anticipate this will improve utilization rates, lower costs, and allow us to respond to client needs more effectively. The complementary equipment base is a strategic rationale for the new Dawson Geophysical. The equipment base which TGC and Dawson operate is highly compatible. The combination will relieve pressure on channel count expansion CapEx in the near future for the combined Company, as the need for higher channel count continues to increase to respond to industry needs. The new Dawson balance sheet will provide increased operational and financial flexibility. The new Dawson balance sheet, based on our respective June 30, 2014, balance sheets, will include approximately $82 million of cash, cash equivalents, and short-term investments; approximately $90 million of working capital; and approximately $28 million of debt. This increased financial flexibility will enable us to react quickly to opportunities according to client needs and more efficiently to market conditions. The new Dawson order book, combined with expanded equipment base and logistical advantages mentioned earlier, should enable us to increase utilization rates while simultaneously lower costs within the US and across the Canadian border. The combined order book should allow us to improve logistics, crew deployment more effectively and consistently. The improvement should allow us to reduce mobilization time and costs; reduce dependence on third-party equipment rental; and take advantage of crew efficiencies, with improved utilization rates for equipment and crews. Each day we avoid being down and every day we improve efficiencies is a day we can increase utilization. With the new Dawson comes expanded human capital. The people we employ are always our greatest asset. The complementary, diverse regional, technical, financial and operational expertise within the new Dawson, we believe, will lead to improved processes, logistics, and a better product for our clients.

In addition to expanded equipment base, client base, order book, and personnel, the combination brings together complementary services. These services include first-in-class health, safety, environmental program and commitment; increased land surveying and permitting capacity; improved IT support; expanded repair capabilities; trucking services; data process; research and development; and dynamite energy source drilling services. Some of these services are common to both companies, and some are services currently provided by one or the other. The new Dawson allows for the potential of less dependence on third-party providers; increased revenue streams; and a better, more timely, cost-effective product for our clients. As we examine the combination and we look at the improved platform of shared people, equipment, and services, we believe there exists at almost every level advantages that will flow through to our shareholders, clients and employees. The seismic market has been and continues to be difficult for all players worldwide, particularly North America. Both companies have struggled with low utilization rates for a variety of reasons in the US. Here at Dawson, our demand has been steady, but we have encountered difficulty in maintaining a high level of utilization due to project delays. Our entry into Canada has been slower than anticipated. TGC, through its Eagle Canada brand, has a long history and done well in Canada for many years. But like us, they have continued to struggle with similar issues to ours in the Lower 48. We operated 10 crews for most of the September quarter but have suffered with weatherrelated issues late in the quarter; several untimely, long crew moves; and short delays on projects for two crews. TGC's utilization has picked up to five crews in the US, and they are in the early stages of the Canadian uptick. Each Company will have costs associated with this transaction in the September and December quarters. We continue to look at ways to rightsize to meet client needs, plan for the future, and maintain higher utilization. We believe the combination of all things we have discussed give us a good opportunity to address these issues. Provided we can execute, put into place solid logistics plans and processes, capitalize on our support services, and reduce outsourcing dependence and improve utilization, a 5% to 10% decrease in overall operational expense is plausible. That said, we have the right size of capacity to meet client needs, increase efficiencies and utilization rates; and we believe there will be value added to clients, shareholders, and employees. And at this point, I will turn control of the call over to Wayne Whitener, CEO, President of TGC Industries. Wayne Whitener - TGC Industries, Inc. - President, CEO, and Director Thank you, Steve, and good morning, everyone. I'd like to start with TGC is very excited about the business combination. We believe TGC brings value to the combined Companies, with over 46 years' experience in the seismic business and having the capacity to field 16 data acquisition crews with some of the newest seismic equipment in the industry. We also bring a strong balance sheet into the mix. TGC has a premier Canadian geophysical company in Eagle Geo, which is a wholly-owned subsidiary of TGC, and after the completion of this transaction will be a wholly-owned subsidiary of the new Dawson and will operate as Eagle Canada. We believe these capabilities and the strength that Dawson brings to the table will make us one of the premier Companies in the geophysical space. With that, I'll turn the call back over to Steve. Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Thank you, Wayne, well said. We'd like to thank everyone for joining this morning's call. We firmly believe that the improved platform of shared people, equipment, and services will increase utilization rates, lower costs, and drive greater value for our clients, shareholders, and employees. We believe that our expanded geographic presence, strength in the balance sheet, and complementary equipment base will improve efficiencies and create new growth opportunities across the combined portfolio. And we believe that the resulting benefits will flow back to all three entities, shareholders, clients, and employees. Dawson Geophysical is 62 years old; Wayne, I believe TGC/Tideland is 47 years old. We believe that our more than 100 years of combined industry experience, equipment -- expanded equipment base, increased financial/internal support services will enable us to shorten cycle times and provide higher-resolution images for our valued clients.

'Thomson Reuters' and the Thomson Reuters logo are registered trademarks of Thomson Reuters and its affiliated companies. Along with that, both Companies have weathered up-and-down cycles over their history. Both Companies have a very similar culture, and both Companies operate from a conservative financial management perspective. I think this combination is a very positive combination for both of us. And with that, Keith, I think we are closed. And I think we'll open the call for questions. Q U E S T I O N A N D A N S W E R Operator (Operator Instructions) Jim Rollyson, Raymond James. Jim Rollyson - Raymond James & Associates, Inc. - Analyst Congrats and good luck on your second attempt at doing this. If I recall correctly, Steve, the last time around, the only thing that shorted out the deal was just stock price moves that took things out of the collar. It wasn't a shareholder support problem, so I imagine that won't be a problem this time. But given the growth for both companies since 2011, the last time you tried to get together, do you think there will be -- or are you guys worried at all about any HSR problems of getting this through? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO No. Jim, I think we'll just go through the normal regulatory approval process that's in place. I think it's a very similar transaction to where we were last time. We did have some stock that got outside the collar and made the deal very confusing for a lot of people as to what actually was supposed to happen when the stocks were outside the range. It did get overwhelming shareholder support. I don't remember the number exactly, but it was up around 90%-something on our shareholder base and about 76% on the TGC side. And so we view this as a very likely outcome and a very positive outcome, just flowing through the normal processes. Jim Rollyson - Raymond James & Associates, Inc. - Analyst That's great. From a broad-based kind of macro thought process here, obviously one of the things you have been facing at Dawson is not a lack of backlog, but trying to get projects done when your customers say they're going to get things done. Can you maybe talk about how you think the combination might help that process? And you mentioned higher resolution, which -- I suspect you mean you're going to take your channel count, divide it, ultimately, over fewer crews. But maybe how some of the working parts will happen once you get this thing closed. Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Jim, there are several things that are in play. Obviously, we have struggled of recent with project delays that have come from a variety of issues: access permits -- land access permits, agricultural activity, client delays. And so what that has put our Company in the position of is having an order book that has some depth to it, maybe, but doesn't quite have the width to it, the breadth that you want. And so we get projects that -- crews that won't be deployed, and then we have a pileup of projects. And so we stretch our equipment base a little bit to get those projects complete. This should aid in that area. With the expanded order book and expanded client base, and not maybe strategically locating crews in the proper areas -- for example, if we move accrue from the Northeast back to the South, and that's mob time, and delay times. And if there's -- it should relieve the one-off projects where we can get groupings of projects in certain areas, and leave crews in those areas and not have the long delays, it should help with -- if we could get the order book where it needs to be, then we can move equipment from one project to the next; hopefully get that stuff laid out; and shorten those downtimes between projects with the aided equipment.

There's a higher channel count demand just to get the thing shot. The densities of channels are getting greater -- continues to get greater. Crews are approaching 12, 13 times 15,000 channels. And so I think we certainly get stretched from an equipment standpoint from time to time and are faced with either a rental or CapEx issue. And I think these guys do the same thing from time to time. And when you've got areas of low -- when we are not fully utilized or they are not fully utilized due to downtime, we should be able to resolve those issues. Jim Rollyson - Raymond James & Associates, Inc. - Analyst Perfect. Last question, Steve -- just maybe talk about customer overlap and/or your kind of combined backlog, how that looks -- shapes up. Thanks. Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO We haven't really taken a hard look at the combined backlog. At this point, Rolly, not something that we are ready to talk about. Obviously, they are early in their Canadian season, as are we. And so they are building some backlog in Canada. I think we are still in a position where we think we can operate 10 crews into calendar 2015. And we are seeing some opportunities for some other projects out there. Wayne, do you want to comment on your utilization? Wayne Whitener - TGC Industries, Inc. - President, CEO, and Director Right now we are operating five crews in the US, and we have three crews in Canada operating. We just activated two crews in Canada early this week, and we had one crew that was operating. So we do have three crews in Canada, and we are hoping to possibly add a fourth crew, maybe towards the end of the fourth quarter. Jim Rollyson - Raymond James & Associates, Inc. - Analyst Very helpful. Thanks, Steve. Thanks, guys. Operator Veny Aleksandrov, FIG Partners. Veny Aleksandrov - FIG Partners - Analyst Good morning Steve, Wayne. My first question is on utilization. Can you spend a little bit more time -- talk about why do you think you're going to improve this utilization? Is it because of the backlog getting now the depth and the width? Or because you are going to have more people, more equipment? How exactly do you plan to improve utilization? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Veny, we are going to have to look at the -- as we move through the process, and as we get to the closing point, we will have to take a hard look at both Companies' backlog levels and where it's located. We really haven't gotten to the point where we have full understanding of that. However, we do know that there are occasions where we have these one-off projects that end up in certain areas of the country, different regions; and we've got movement of crews going back and forth. And so we anticipate that we do -- while there is some overlap in areas of operation, there's a little bit of separation on some level of concentration of where projects might be. For example, we had the situation in 2013 where we -- early in the year we had a high concentration of our activity was based in one area with heavy agricultural activity, and then it broke loose. And when it broke loose, we didn't have enough equipment to service all that.

At the same time I am confident that there were other projects and other needs at that given time where our equipment -- where the combined equipment base could have been better utilized. I'm not saying that early on, we're going to immediately have full utilization between the -- you know, with everything -- with all the equipment that both Companies own. But I think once we get a hard look at it, and -- you know, the more projects we have in place, the better we can plan. So that's our theory. That's our thought process. We thought that in the past, and we continue to think that's possible. It will not be an overnight thing. The market is, as everybody is well aware, is still tough out there. There's an awful lot of uncertainty in a lot of areas --obviously, as you've seen the past few days, week or so of trading -- 30 days, I guess. And so we will have an expanded client base, more contacts. It's still a highly competitive market. It's still a highly capital-intensive market. We think that we will relieve some of that capital intensity going forward. So, Veny, we think there's a lot of areas. But here, again, some things we really can't get into the details on until we actually have the new Company put together. Veny Aleksandrov - FIG Partners - Analyst I understand. Thank you. And then Canada -- the deal should close sometime in Q1, but by then, Canada -- the season is going to be almost over. What are your plans in terms of Dawson for this season? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO We are still looking at projects, and our group is still bidding projects up in Canada. We've got a good group of folks up there. We've done some projects. It's just been a tougher entry for us than we had hoped. A lot of that has been softer Canadian market conditions. And so I think from our perspective in the Canadian corridor, it's probably too early to tell, although I think that it's probably at recent-year levels for us. Wayne, if you want to comment on the Canadian perspective from your side? Wayne Whitener - TGC Industries, Inc. - President, CEO, and Director It's still a soft market in Canada, as well. But, you know, we pretty much have one of the preferred companies up there with Eagle Canada that's very well thought of and has a strong client base up there. We're hoping to run, as I mentioned, three to four crews in the fourth quarter. And our hope is to run five to six crews in the first quarter of next year. That being said, it's a little bit early in the season for us to totally know what the backlog is going to be like in the first quarter. But we are very optimistic on the amount of work that we will be receiving in the Canadian operation. Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Veny, I want to back up for just a minute. We've had two questions here back to back on the utilization. And, clearly, that is an issue we've struggled with recently; and, obviously, TGC has struggled with -- and obviously it's been a struggle all across not just the Lower 48 and North America but worldwide. We are in a cycle. These cycles happen. We think this combination gives us the ability to grow and take -- meet -- look at new opportunities in this cycle; positions us for the uptick. There will be an uptick. In the meantime, we've got two of the best management teams, depth of management operational expertise that you can find in the Lower 48. We've been here 109 years or something, working in these markets. We've seen changes. We've seen things move up and down. We've seen technology changes. And both Companies have a history responding to that well and executing that.

'Thomson Reuters' and the Thomson Reuters logo are registered trademarks of Thomson Reuters and its affiliated companies. And part of this is going to be utilization. Demand is still going to stay what it is; we understand that. Competition is still fierce out there. It will continue to be fierce. It's always been fierce in our business. The key to our success has been utilization and efficiency. If we put the two together, hopefully we can rightsize this thing, where we can take advantage of efficiency -- which both Companies have been doing -- without sacrificing utilization rates on the back side. That's going to be one issue we have to deal with, and we've got some really strong operational folks and experts on both sides of the table that, I think, when those folks join forces and figure this out, they will allow us to expand even further on our comments. Second to that is: we have services that we can bring to the table for them; they have services that they can bring to the table for us. We have idle capacity at times for background services; they have idle capacity. We've got support services that they don't have. And so if we can reduce that dependence on outsourcing, if we can improve in the equipment movement back and forth across the border -- we've thrown out a 5% to 10% number of combined operating expense; but when you look at that, there are a lot of ways you can get to that number. And so it is utilization. But there is also some cost effect that we are going to be taking a hard look at, primarily based on reduction of outsourcing concepts. Veny Aleksandrov - FIG Partners - Analyst Thank you, I do appreciate that. And very quick last one: do you used to pay dividends? And then what's (technical difficulty) share count? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Veny, it's early in this process. I think the implementation or continuation of a dividend policy will be at the discretion of new Board -- the new Company Board. Our focus right now is to get this thing through closing. We are going to put this thing together, because we think it makes sense for both Companies; it makes sense for our employees, our shareholders, and our clients. So we are focused on doing that: get this thing to closing, start looking at the combined Company and how we execute. And then, as Boards do, we will address certain issues once the new Company Board is put together. Veny Aleksandrov - FIG Partners - Analyst Appreciate it. Thank you. Operator Jason Wangler, Wunderlich Securities. Jason Wangler - Wunderlich Securities, Inc. - Analyst Morning, guys, and congrats. I just kind of had one, and you kind of alluded to it, Steve, as far as being able to kind of support each other. You've been good about telling us, kind of in general, where you guys are active. Are those the same kind of regions that TGC and their crews are? Or is there new areas in the US? Obviously the Canada market is going to be a big bump, but is there anywhere else in the US that they're going to make you strong? Or is it more just kind of bolstering the areas that you're already at? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Obviously, the Canadian issue will be a strong -- from our side will be an expansion -- growth opportunity for us. The seismic industry in the Lower 48 has some regional component to it. There are operators that work in different areas, and they stay focused, whether they are conventional or they are unconventional players.

All rights reserved. Republication or redistribution of Thomson Reuters content, including by framing or similar means, is prohibited without the prior written consent of Thomson Reuters. 'Thomson Reuters' and the Thomson Reuters logo are registered trademarks of Thomson Reuters and its affiliated companies. And believe it or not, there are still some conventional things that are done out there. And I think we have some long-standing relationships with people who operate in various regions of the country, as does TGC. And then we have the larger unconventional issue. And the good thing about seismic assets is they are all on wheels. You can be anywhere in the country that you want to be. And demand and client activity takes you to certain areas. Not -- I don't think either Company camps in one particular area at any given time. Obviously, there are some slight relationship/regional strength stuff, but I think just looking at the combined and being able to more strategically locate some of these assets to meet the client needs -- it's going to help our client base. I mean, theoretically, they won't have to wait for mobilization and the costs associated with such things. So I think we're just going to have to take a hard look at this thing post-transaction, Jason, to get a real feel for the nitty-gritty, in-the-weeds details. Jason Wangler - Wunderlich Securities, Inc. - Analyst I appreciate it. Congrats again. Good luck. Operator (Operator Instructions) Gary Lenhoff, Great Lakes Advisors. Gary Lenhoff - Great Lakes Advisors - Analyst Steve, the structure of the transaction -- is there a particular reason why the -- Dawson is merging into the TGC subsidiary? Is there a tax reason, NOL? Something along those lines? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO No, Gary. It's -- we've taken a hard look at this, and we think for -- it is a complicated process. We think for transactional purposes, the ease of transaction, and securing shareholder votes that this is a good process to go through. It basically is a merger, a combination of two strong Companies. And so whether -- however the deal is structured -- you know, last time we had a different structure. We had some collar arrangements, and we had some other things that made it difficult. But the combination makes a lot of sense. The process by which we are going through, where they are going to reverse split 1-for-3 and then pay us -- you know, exchange post-split shares, we will end up with north of 20 million shares outstanding, held by our float. And so last time we got very high shareholder approval. The threshold this time is 66.67% on both sides. Gary Lenhoff - Great Lakes Advisors - Analyst Okay. You touched on CapEx. Can you give us some sense -- if we simply -- if we look at the CapEx -- estimates are not forecasts, so I don't want to suggest you gave guidance; but you have talked about CapEx going forward, as has TGC to some extent. Can you give us some sense of what you think combined CapEx should be or what maintenance CapEx -- some idea of what CapEx budget might look like post-transaction? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Gary, right now I think our strategy, moving in -- from the Dawson perspective, moving into fiscal 2015 for us, which we just started fiscal 2015; and they're in their Q4 of 2014, so their budget will be set -- or probably has not been set yet. But I think both Companies have looked into 2015 at a maintenance capital level. And I think that probably is $2 million, $3 million on their side. It's probably $6 million to $8 million, $10 million, something like that for us, Gary, depending on fleets, and small rolling stock, and those types of things.

All rights reserved. Republication or redistribution of Thomson Reuters content, including by framing or similar means, is prohibited without the prior written consent of Thomson Reuters. 'Thomson Reuters' and the Thomson Reuters logo are registered trademarks of Thomson Reuters and its affiliated companies. My gut feel is that we are going to stay at this point at maintenance cap levels. And I anticipate that through the combination, there will be a reduction of the maintenance cap levels going forward independently. Gary Lenhoff - Great Lakes Advisors - Analyst Great. Again, thanks very much. Appreciate it. Operator Jeremy Javidi, Columbia Management Group. Jeremy Javidi - Columbia Management Group - Analyst So keying off part of Steve's prepared remarks, you mentioned a 5% overall expense reduction. Is that coming out of both cost of goods sold as well as SG&A, or are you specifically talking about SG&A? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO I don't think it's an SG&A issue. I think it's an operational issue. From a high level, both Companies have been conservatively managed and are rightsized. And so when we look at cost savings going forward, we are looking at relief of third-party services, relief of equipment rental, increased utilization, looking at relief from mobilization and demob costing. For example, they provide shot hole drilling services. We do not. We outsource all of that. Now, the combined Company -- there still will be outsourcing and shot hole drilling services. However, with a broader base to work from, theoretically we should be able to utilize their services better. We outsource all of our cable and geophone repair. They do a lot of that internally. Now, that will relieve to a certain extent some level of outsourced repair costs. We have six survey crews. They have six survey crews. And we keep ours busy. And to a certain extent they keep theirs busy. And we offer permitting services at a larger scale than they do. And so being able to use those third-party services across a larger platform in broader geographical regions, I think, will give us an advantage. So those are the types of areas, Jeremy, where we are looking and would anticipate reduction in overall operating expense. Jeremy Javidi - Columbia Management Group - Analyst Steve, given that great description of where the pockets of operating expense leverage could be had. Would it be fair to say this is a first cut at it, given the numerous pockets of opportunities? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO I'm sorry, can you repeat that question? I lost you for a second. Jeremy Javidi - Columbia Management Group - Analyst Would be fair to say the 5% overall expense reduction might be conservative, given the numerous pockets of opportunities? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO

'Thomson Reuters' and the Thomson Reuters logo are registered trademarks of Thomson Reuters and its affiliated companies. Without the risk of jumping out too far onto a guidance limb, which neither Company does, in our comments we said a 5% to 10% reduction. And obviously, Jeremy, our goal is always to meet at some time frame -- it's going to take a while to get this rolled in. We all understand that. So from a timing perspective, I don't think you judge this transaction, this deal, in the first 90 days. And as we said all along -- and they are in the same boat -- we are a cyclical business. We have ups and downs quarter to quarter. Sometimes they last longer than that. We are cyclical within cyclical. And so our companies are one that have to be looked at over a longer period of time. And we are viewing this transaction as a long-term growth opportunity. And so when we go into it, we see some things that we can do that we think we can implement that are in the 5% to 10% range. And I think our goal, as it always has been, is to meet our expectations or meet our anticipation and exceed that. And so I would think that 5% would be a conservative number. We are both -- Wayne and I are both conservative in our comments by nature. And so we think that's there, and we just got to go to work. And we've got the best management team, best operational folks -- certainly, in our opinion, in the Lower 48 and in North America. And I think we've got the right people that can bring a best of class from both sides. I know that there are things at this Company that we are about to get involved with do extremely well. They have a great, long history and a great run. And so do we. And between that, we think we will understand and find ways to put these two together. It's a very similar culture, strong balance sheet, great equipment base. I think we've got the right people in the right places in the right time to get this thing done and improve. Is it going to happen in Q1 of 2015? No. But give it some time, and we will get there. Jeremy Javidi - Columbia Management Group - Analyst Thank you very much for the answers. Operator Veny Aleksandrov, FIG Partners. Veny Aleksandrov - FIG Partners - Analyst I have a question about the (technical difficulty) Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Veny, try that one more time. I'm having a hard time in this room. Veny Aleksandrov - FIG Partners - Analyst I'm sorry, yes. The connection is not good. The authorized share count for TGC Industries -- there are some unissued shares. And I think that these continue (technical difficulty)? Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Veny, I think the question is -- and I believe that TGC Industries has a share count authorization of 35 million. Isn't that correct, Wayne?

Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO And they currently have approximately 22 million outstanding. And so they're going to go through the 3-to-1 reverse split that is going to put their current 22 million share count down to 7 million, roughly 7.3 million. Then they are going to issue 1.76 shares of the post-split shares to the Dawson shareholders, at which time there will be some certificate changes, and reissuance, and those types of things that will occur. It will be -- approximately 14.2 million shares will be issued, the post-split shares, which should put the share count somewhere in the general vicinity of the current TGC current shares outstanding. Slight change to that. We don't have the exact numbers. There's some things that need to go into that. And so part of the 3-to-1 split is to make room underneath that charter of 35 million shares outstanding in addition to the other things that we've talked about. Veny Aleksandrov - FIG Partners - Analyst Thank you. I appreciate it. Operator Thank you. And as there are no more questions at the present time, I would like to turn the call back over to management for any closing comments. Steve Jumper - Dawson Geophysical Company - Chairman, President, and CEO Thank you, Keith. We appreciate everybody calling in and listening in. Obviously, both management teams and both Board of Directors are enthusiastic about this for our employees, and we are enthusiastic about it for our shareholders, and we are enthusiastic about it for our client base. We think the combination brings together an awful lot of positives. We are in a tough market; we understand that. We think this is the right deal. We understand that there are -- the structure is a little bit complicated, but it's being done for the right reasons. And it's being done to get this deal -- to get the votes approved and get this deal done. I think it creates an awful lot of opportunities for us going forward. We greatly appreciate everybody's support, from our client base to our shareholder base, our employee base. And we look forward to talking to each of you in the near future. We look forward to getting your vote. And we are asking that you vote with us to approve this deal. Thank you very much. Have a great day. Operator Thank you. The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.
