 Exhibit 10.23 

FORM OF INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (“Agreement”) is made as of October [●], 2016 by and between Smart Sand, Inc., a Delaware
corporation (the “Company”), and [●] (“Indemnitee”). 
 RECITALS 

WHEREAS, highly competent persons have become more reluctant to serve publicly-held corporations as directors or in other capacities unless
they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation; 

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in order to attract and retain qualified
individuals, the Company will maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities; 

WHEREAS, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to
expensive and time-consuming litigation relating to, among other things, matters that traditionally would have been brought only against the Company or business enterprise itself; 

WHEREAS, the Company’s Second Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) and Second
Amended and Restated Bylaws (the “Bylaws”) require indemnification of the officers and directors of the Company. Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware
(“DGCL”). The Certificate of Incorporation, Bylaws and the DGCL expressly provide that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and
members of the board of directors, officers and other persons with respect to indemnification; 
 WHEREAS, the Board has determined that the
increased difficulty in attracting and retaining qualified individuals to serve as directors and officers is detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such persons that there will
be increased certainty of such protection in the future; 
 WHEREAS, it is reasonable, prudent and necessary for the Company contractually
to obligate itself to indemnify, and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so
indemnified; 
 WHEREAS, this Agreement is a supplement to and in furtherance of the Certificate of Incorporation and Bylaws of the Company
and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; 

 WHEREAS, Indemnitee does not regard the protection available under the Bylaws and insurance as
adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take
on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified; 
 [WHEREAS, Indemnitee has
certain rights to indemnification and/or insurance provided by [Clearlake Capital Partners, LLC] (“Clearlake”) or affiliates of Clearlake that Indemnitee and Clearlake intend to be secondary to the primary obligation of the Company
to indemnify Indemnitee as provided herein, with the Company’s acknowledgment of and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve as a director or in any other capacity for the Company or any
of its subsidiaries or any Enterprise;]1and 
 NOW, THEREFORE, in consideration of the
premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as follows: 
 Section 1. Services
to the Company. Indemnitee agrees to serve as [a director] [an officer] of the Company. Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or any obligation imposed by operation
of law), in which event the Company shall have no obligation under this Agreement to continue Indemnitee in such position. This Agreement shall not be deemed an employment contract between the Company (or any of its subsidiaries or any Enterprise)
and Indemnitee. Indemnitee specifically acknowledges that Indemnitee’s employment with the Company (or any of its subsidiaries or any Enterprise), if any, is at will, and the Indemnitee may be discharged at any time for any reason, with or
without cause, except as may be otherwise provided in any written employment contract between Indemnitee and the Company (or any of its subsidiaries or any Enterprise), other applicable formal severance policies duly adopted by the Board, or, with
respect to service as a director or officer of the Company, by the Certificate of Incorporation, the Bylaws and the DGCL. The foregoing notwithstanding, this Agreement shall continue in force after Indemnitee has ceased to serve as [an officer] [a
director] of the Company. 
 Section 2. Definitions. As used in this Agreement: 

(a) A “Change in Control” shall be deemed to occur upon the earliest to occur after the date of this Agreement of any of the
following events:

securities; 
  

	1 	NTD: Bracketed provisions apply only to Clearlake directors. 

 (ii) Change in Board of Directors. During any period of two (2) consecutive years (not

Company to effect a transaction described in Sections 2(a)(i), 2(a)(iii) or 2(a)(iv)) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the directors then still
in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved or who was otherwise nominated by Clearlake or any of its affiliates, cease for any reason to constitute at
least a majority of the members of the Board; 
 (iii) Corporate Transactions. The effective date of a merger or consolidation of the
Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or

(v) Other Events. There occurs any other event of a nature that would be required to be reported in response to Item 6(e) of Schedule

For purposes of this Section 2(a), the following terms shall have the following meanings: 

(A) “Exchange Act” shall mean the Securities Exchange Act of 1934, as amended. 

(B) “Person” shall have the meaning as set forth in Sections 13(d) and 14(d) of the Exchange Act; provided, however,
that Person shall exclude (i) the Company, (ii) any trustee or other fiduciary holding securities under an employee benefit plan of the Company, and (iii) any corporation owned, directly or indirectly, by the stockholders of the
Company in substantially the same proportions as their ownership of stock of the Company. 

 (C) “Beneficial Owner” shall have the meaning given to such term in

(b) “Corporate Status” describes the status of a person who is or was a director, officer, employee, agent or fiduciary of the
Company or of any Enterprise. 
 (c) “Disinterested Director” means a director of the Company who is not and was not a party to

permitted by applicable law, successfully establishing a right to indemnification under this Agreement, whether in whole or part. Expenses also shall include Expenses incurred in connection with any appeal resulting from any Proceeding and any
federal, state, local or foreign taxes imposed on Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement, including without limitation the premium, security for, and other costs relating to any cost bond,

(f) “Independent Counsel” means a law firm, or a member of a law firm, that is experienced in matters of corporate law and neither

indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent Counsel” shall not include any
person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement. The
Company agrees to pay the reasonable fees and expenses of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Expenses, claims, Liabilities and damages arising out of or relating to this Agreement or its
engagement pursuant hereto. 

 (g) “Liabilities” means all claims, liabilities, damages, losses, judgments (including

(h) The term “Proceeding” shall include any actual, threatened, pending or completed action, suit, arbitration, alternate dispute
resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened, pending or completed proceeding, and any appeal thereof, whether brought by or in the right of the Company or otherwise and whether of a civil,
criminal, administrative or investigative nature, in which Indemnitee was, is or will be involved as a party or otherwise by reason of the Corporate Status of Indemnitee, by reason of any action taken by Indemnitee or of any inaction on
Indemnitee’s part while acting in such Corporate Status, in each case whether or not serving in such capacity at the time any Liability or Expense is incurred for which indemnification, reimbursement, or advancement of Expenses can be provided
under this Agreement. If the Indemnitee believes in good faith that a given situation may lead to or culminate in the institution of a Proceeding, this shall be considered a Proceeding under this paragraph.

tax assessed with respect to any employee benefit plan; references to “serving at the request of the Company” shall include any service as a director, officer, employee or agent of the Company which imposes duties on, or involves services
by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the best interests of the participants
and beneficiaries of an employee benefit plan shall be deemed to have acted in manner “not opposed to the best interests of the Company” as referred to in this Agreement. 

Section 3. Indemnity in Third-Party Proceedings. The Company shall indemnify Indemnitee in accordance with the provisions of this
Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this Section 3, Indemnitee
shall be indemnified against all Expenses and Liabilities actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and
in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal proceeding had no reasonable cause to believe that his conduct was unlawful. 

 Section 4. Indemnity in Proceedings by or in the Right of the Company. The Company shall
indemnify Indemnitee in accordance with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant
to this Section 4, Indemnitee shall be indemnified against all Expenses and Liabilities actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim, issue or matter therein, if
Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. No indemnification for Expenses or Liabilities shall be made under this Section 4 in respect of any
claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that the Delaware Court of Chancery or any court in which the Proceeding was brought shall determine
upon application that such indemnification may be made. 
 Section 5. Indemnification for Expenses of a Party Who is Wholly or Partly
Successful. Notwithstanding any other provisions of this Agreement, to the extent that Indemnitee is a party to (or a participant in) and is successful, on the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter
therein, in whole or in part, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the
merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf in connection with each
successfully resolved claim, issue or matter. If the Indemnitee is not wholly successful in such Proceeding, the Company also shall indemnify Indemnitee against all Expenses reasonably incurred in connection with a claim, issue or matter related to
any claim, issue, or matter on which the Indemnitee was successful. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to
be a successful result as to such claim, issue or matter. 
 Section 6. Indemnification For Expenses of a Witness. Notwithstanding
any other provision of this Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness in any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually
and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 
 Section 7. Additional
Indemnification. 
 (a) Notwithstanding any limitation in Sections 3, 4, 5, or 6, the Company shall indemnify Indemnitee to the fullest
extent permitted by law if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all reasonable Expenses and Liabilities
actually incurred by Indemnitee in connection with the Proceeding. 
 (b) For purposes of Section 7(a), the meaning of the phrase
“to the fullest extent permitted by law” shall include, but not be limited to: 

 i. to the fullest extent permitted by the provision of the DGCL that authorizes or contemplates
additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL, and 
 (ii) to the
fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 

Section 8. Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make
any indemnity in connection with any claim made against Indemnitee: 
 (a) for an accounting of profits made from the purchase and sale (or
sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of state statutory law or common law; or 

(b) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any
Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board of Directors of the Company authorized the Proceeding (or any part of any Proceeding) prior to its
initiation, (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law, or (iii) the Proceeding is one to enforce Indemnitee’s rights under this Agreement.

 Section 9. Advances of Expenses. Notwithstanding any provision of this Agreement to the contrary, the Company shall advance the
Expenses incurred by Indemnitee or on Indemnitee’s behalf in connection with any Proceeding within 30 days after the receipt by the Company of a statement or statements requesting such advances from time to time, whether prior to or after final
disposition of any Proceeding. Advances shall be unsecured and interest free. Advances shall be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate entitlement to indemnification
under the other provisions of this Agreement. Advances shall include any and all reasonable Expenses incurred pursuing an action to enforce this right of advancement, including Expenses incurred preparing and forwarding statements to the Company to
support the advances claimed. The Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement which shall constitute an undertaking providing that the Indemnitee undertakes to repay the advance to the
extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company. This Section 9 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 8. 

Section 10. Procedure for Notification and Defense of Claim. 

(a) To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith
such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification, not later than thirty
(30)

 
days after receipt by Indemnitee of notice of the commencement of any Proceeding. The omission to notify the Company will not relieve the Company from any liability which it may have to
Indemnitee otherwise than under this Agreement. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. 

(b) The Company will be entitled to participate in the Proceeding at its own expense. 

Section 11. Procedure Upon Application for Indemnification. 

(a) Upon written request by Indemnitee for indemnification pursuant to the first sentence of Section 10(a), a determination, if required
by applicable law, with respect to Indemnitee’s entitlement thereto shall be made in the specific case: (i) if a Change in Control shall have occurred, by Independent Counsel in a written opinion to the Board of Directors, a copy of which
shall be delivered to Indemnitee; or (ii) if a Change in Control shall not have occurred, at the sole discretion of the Indemnitee, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of the Board,
(B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the Board, (C) by Independent Counsel in a written opinion to the Board, a copy of which shall be
delivered to Indemnitee or (D) by the stockholders of the Company; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such determination. Indemnitee
shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or
information which is not privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any Expenses (including attorneys’ fees and disbursements) incurred by
Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and
agrees to hold Indemnitee harmless therefrom. 
 (b) In the event the determination of entitlement to indemnification is to be made by
Independent Counsel pursuant to Section 11(a) hereof, the Independent Counsel shall be selected as provided in this Section 11(b). If a Change in Control shall not have occurred, the Independent Counsel shall be selected by the Board of
Directors, and the Company shall give written notice to Indemnitee advising him of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee (unless
Indemnitee shall request that such selection be made by the Board of Directors, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so
selected. In either event, Indemnitee or the Company, as the case may be, may, within 10 days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written objection to such
selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 2 of this Agreement, and the

 
objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written
objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If, within 20 days after
submission by Indemnitee of a written request for indemnification pursuant to Section 10(a) hereof, no Independent Counsel shall have been selected and objected to, either the Company or Indemnitee may petition a court of competent jurisdiction
for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person
as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 11(a) hereof. Upon the due commencement of any judicial proceeding or
arbitration pursuant to Section 13(a) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 

(c) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement
shall be required to be made prior to the final disposition of the Proceeding; provided that, in absence of any such determination with respect to such Proceeding, the Company shall pay all Liabilities and advance Expenses with respect to such
Proceeding as if the Company had determined the Indemnitee to be entitled to indemnification and advancement of Expenses with respect to such Proceeding. 

Section 12. Presumptions and Effect of Certain Proceedings. 

(a) In making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such
determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence in connection
with the making by any person, persons or entity of any determination contrary to that presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to have made a determination prior to the commencement of any
action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or Independent Counsel) that
Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(b) If the person, persons or entity empowered or selected under Section 11 of this Agreement to determine whether Indemnitee is entitled
to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall be deemed to have been made and Indemnitee
shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for
indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person,

 
persons or entity making the determination with respect to entitlement to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or
information relating thereto; and provided, further, that the foregoing provisions of this Section 12(b) shall not apply (i) if the determination of entitlement to indemnification is to be made by the stockholders pursuant to
Section 11(a) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination the Board of Directors has resolved to submit such determination to the stockholders for their
consideration at an annual meeting thereof to be held within seventy five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of stockholders is called within fifteen (15) days after such
receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made thereat, or (ii) if the determination of entitlement to
indemnification is to be made by Independent Counsel pursuant to Section 11(a) of this Agreement. 
 (c) The termination of any
Proceeding or of any claim, issue or 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 Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any
criminal Proceeding, that Indemnitee had reasonable cause to believe that his conduct was unlawful. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

(d) Reliance as Safe Harbor. For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if
Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the officers, directors, managers, employees, agents or representatives of the
Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert
selected with the reasonable care by the Enterprise. The provisions of this Section 12(d) shall not be deemed to be exclusive or to limit in any way the other circumstances in which the Indemnitee may be deemed to have met the applicable
standard of conduct set forth in this Agreement. 
 (e) Actions of Others. The knowledge and/or actions, or failure to act, of any
director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

Section 13. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 11 of this Agreement that Indemnitee is not entitled to
indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 9 of this Agreement, (iii) no determination of entitlement to indemnification shall have been made pursuant to
Section 11(a) of this Agreement within 45 days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Section 5 or 6 or the

 
last sentence of Section 11(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, or (v) payment of indemnification pursuant to
Section 3, 4 or 7 of this Agreement is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification, Indemnitee shall be entitled to an adjudication by a court of his entitlement to such
indemnification or advancement of Expenses. Alternatively, Indemnitee, at his option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association.
Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 13(a); provided,
however, that the foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce his rights under Section 5 of this Agreement. The Company shall not oppose Indemnitee’s right to seek any such adjudication or
award in arbitration. 
 (b) In the event that a determination shall have been made pursuant to Section 11(a) of this Agreement that
Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 13 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be
prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 13 the Company shall have the burden of proving Indemnitee is not entitled to indemnification or advancement of
Expenses, as the case may be. 
 (c) If a determination shall have been made pursuant to Section 11(a) of this Agreement that
Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 13, absent (i) a misstatement by Indemnitee of a material fact, or an
omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) The Company shall be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 13 that
the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement. 

(e) The Company shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days
after receipt by the Company of a written request therefore) advance such expenses to Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under
this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or
insurance recovery, as the case may be. 
 Section 14. Non-exclusivity; Survival of Rights; Insurance; [Primacy of Indemnification;]
Subrogation. 

 (a) 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 Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders or a resolution of directors, or
otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his Corporate Status
prior to such amendment, alteration or repeal. To the extent that a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement of Expenses than would be afforded currently under the Bylaws and
this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and
every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 
 (b) The Company shall, if commercially
reasonable, obtain and maintain in effect during the entire period for which the Company is obligated to indemnify Indemnitee under this Agreement, one or more policies of insurance with reputable insurance companies to provide the directors and
officers of the Company with coverage for losses from wrongful acts and omissions and to ensure the Company’s performance of its indemnification obligations under this Agreement. 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 such director, officer, employee or agent under such policy or policies. In all such policies, Indemnitee shall be named as an insured in such a manner as to
provide Indemnitee with the same rights and benefits as are accorded to the most favorably insured of the Company’s directors and officers. At the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company shall give
prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies. 
 (c) [The Company
hereby acknowledges that Indemnitee has certain rights to indemnification, advancement of expenses and/or insurance provided by Clearlake and certain of Clearlake’s affiliates that, directly or indirectly, (i) are controlled by,
(ii) control or (iii) are under common control with, Clearlake (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are
primary and any obligation of the Fund Indemnitors to advance Expenses or to provide indemnification for the same Liabilities or Expenses incurred by Indemnitee is secondary), (ii) that it shall be required to advance the full amount of
Expenses actually incurred by Indemnitee and shall be liable for the full amount of all Liabilities and Expenses as required by the terms of this Agreement and the Certificate of Incorporation or Bylaws (or any other agreement between the Company
and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors, and (iii) that it irrevocably waives, relinquishes and releases the Fund Indemnitors from any and all claims against the Fund Indemnitors for
contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or 

 
payment by the Fund Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund
Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Fund Indemnitors are
express third party beneficiaries of the terms of this Section 14(c).] 
 (d) [Except as provided in Section 14(c)
above,] in the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee [(other than against the Fund Indemnitors)], who shall execute all papers required
and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

(e) [Except as provided in Section 14(c) above,] the Company shall not be liable under this Agreement to make any payment of
amounts otherwise indemnifiable (or for which advancement is provided) hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 

(f) [Except as provided in Section 14(c) above,] the Company’s obligation to indemnify or advance Expenses hereunder to
Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount Indemnitee
has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. 

Section 15. Duration of Agreement. This Agreement shall continue until and terminate upon the later of: (a) 10 years after the
date that Indemnitee shall have ceased to serve in any Corporate Status or (b) 1 year after the final termination of any Proceeding (including any rights of appeal thereto) in respect of which Indemnitee is granted rights of indemnification or
advancement of Expenses hereunder and of any Proceeding commenced by Indemnitee pursuant to Section 13 of this Agreement relating thereto (including any rights of appeal thereto). This Agreement shall be binding upon the Company and its
successors and assigns and shall inure to the benefit of Indemnitee and his heirs, executors and administrators. 

 Section 16. Severability. If any provision or provisions of this Agreement shall be held
to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any Section of this Agreement
containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by
law; (b) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions
of this Agreement (including, without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so
as to give effect to the intent manifested thereby. Without limiting the generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws. In the event any
provision hereof conflicts with any applicable law, such provision shall be deemed modified, consistent with the aforementioned intent, to the extent necessary to resolve such conflict. 

Section 17. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in
order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director or officer of the Company. 

(b) Without limiting any of the rights of Indemnitee under the Certificate of Incorporation or Bylaws as they may be amended from time to
time, this Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to
the subject matter hereof. 
 Section 18. Modification and Waiver. No supplement, modification, waiver or amendment of this Agreement
shall be binding unless executed in writing by the parties thereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute a
continuing waiver. 
 Section 19. Notice by Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being served
with any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advancement of Expenses covered hereunder. The failure of Indemnitee to so
notify the Company shall not relieve the Company of any obligation which it may have to the Indemnitee under this Agreement or otherwise. 

 Section 20. Notices. All notices, requests, demands and other communications under this
Agreement shall be in writing and shall be deemed to have been duly given (a) if delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, (b) when sent by confirmed electronic or
facsimile if sent during normal business hours of the recipient, and if not so confirmed, then, on the next business day, (c) if mailed by certified or registered mail with postage prepaid, on the third business day after the date on which it
is so mailed, or (d) if sent via a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt, on the next business day after the dae on which it is so mailed: 

(a) If to Indemnitee, at the address indicated on the signature page of this Agreement, or such other address as Indemnitee shall provide to
the Company. 
 (b) If to the Company to

Avenue, Suite 350 
 The Woodlands, Texas 77380 

Attn: [Chief Financial Officer] 
 or to any other
address as may have been furnished to Indemnitee by the Company. 
 Section 21. Contribution. To the fullest extent permissible under
applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for
judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in
light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the
relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 

Section 22. Applicable Law and Consent to Jurisdiction. This Agreement and the legal relations among the parties shall be governed by,
and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant to Section 10(a) of this Agreement, the
Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Chancery Court of the State of Delaware (the “Delaware

and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum. 

Section 23. Identical Counterparts. This Agreement may be executed in one or more counterparts, each of which shall for all purposes be
deemed to be an original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of this Agreement.

 Section 24. Miscellaneous. Use of the masculine pronoun shall be deemed to include usage of the feminine pronoun where

EXECUTION VERSION 

AGREEMENT 
 This Agreement
(this “Agreement”) is made and entered into as of October 18, 2016 by and among Esterline Technologies Corporation (the “Company”) and the entities and natural persons set forth in the signature pages hereto (collectively,
“FPA”) (each of the Company and FPA, a “Party” to this Agreement, and collectively, the “Parties”). 
 RECITALS

 WHEREAS, as of the date hereof, FPA may be deemed to beneficially own shares of Common Stock of the Company (the “Common
Stock”) totaling, in the aggregate, 3,690,774 shares (the “Shares”), or approximately 12.6%, of the Common Stock issued and outstanding on the date hereof; and 

WHEREAS, as of the date hereof, the Company and FPA have determined to come to an agreement relating to the matters set forth in this
Agreement. 
 NOW, THEREFORE, in consideration of the foregoing premises and the mutual covenants and agreements contained herein, and for
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto, intending to be legally bound hereby, agree as follows: 

 

	Section 1.	Board Matters, Nomination and Election of Directors and Related Agreements. 

 (a)
Nomination and Appointment of the New Independent Director. Promptly following the execution of this Agreement, the Board shall take all necessary actions (including increasing the number of members of the Board of Directors of the Company
(the “Board”) to ten) to nominate and appoint Mr. Nils Larsen as a director of the Company (the “New Independent Director”) with a term expiring at the 2017 annual meeting of stockholders (the “2017 Annual
Meeting”). In due course, the Board and the appropriate committee(s) of the Board shall take all necessary actions to nominate the New Independent Director for election at the 2017 Annual Meeting for a further term expiring at the 2020 annual
meeting of stockholders (the “2020 Annual Meeting”). 
 (b) Nomination and Election of the 2017 Director Nominee. It is
currently anticipated that one of the existing directors whose term expires at the 2017 Annual Meeting intends to retire and cease any service as a director (the “Retiring Director”). The Nominating and Corporate Governance Committee (the
“Nominating Committee”) is undertaking a process to select a candidate to replace the Retiring Director that will stand for election as a director on the Board at the 2017 Annual Meeting (the “2017 Director Nominee”) with a term
expiring at the 2020 Annual Meeting. Promptly following the execution of this Agreement, FPA shall have the right to submit potential candidates (the “FPA Candidates”) to the Nominating Committee to be considered as part of its 2017
Director Nominee process. The FPA Candidates: (i) shall qualify as “independent” pursuant to the Securities and Exchange Commission (“SEC”) and the New 

 
York Stock Exchange, Inc. listing standards, (ii) shall not be an Affiliate or Associate of FPA (as such terms are defined in Section 2 below), and (iii) shall have credentials
consistent with the criteria established by the Nominating Committee as to director qualifications (such criteria as has been provided to FPA in writing prior to the execution of this Agreement) (clauses (i)-(iii), together, the “Director
Criteria”). The Nominating Committee shall give due and careful consideration to the FPA Candidates and share with FPA information pertaining to the other final proposed candidates it considers for the 2017 Director Nominee position. However,
if no 2017 Director Nominee has been nominated by the time of the mailing of the Company’s definitive proxy statement for the 2017 Annual Meeting, the Board (i) shall take all necessary actions to set the size of the Board at 9 seats prior
to the 2017 Annual Meeting and (ii) recommend, support and solicit proxies for the election of only three nominees at the 2017 Annual Meeting (including the New Independent Director). 

(c) Solicitation Efforts. The Company will recommend, support and solicit proxies for the election of the New Independent Director and
the 2017 Director Nominee, if then identified and approved, at the 2017 Annual Meeting in the same manner as for any other nominees of the Company at the 2017 Annual Meeting. In the event that the 2017 Director Nominee is appointed to the Board
after the 2017 Annual Meeting (notwithstanding Section 1(b)) or a Substitute Nominee or Replacement Nominee is appointed to the Board in accordance with Section 1(d) below, then the Company will recommend, support and solicit proxies for
the election of such 2017 Director Nominee, Substitute Nominee or Replacement Nominee at the first annual meeting of stockholders of the Company following his or her appointment if such nominee is up for election at such annual meeting in the same
manner as for any other nominees of the Company at such annual meeting. 
 (d) Vacancies. So long as FPA continues to beneficially
own a “net long position” (as such term is defined in Rule 14e-4 of the Securities Exchange Act of 1934, as amended, or the rules or regulations promulgated thereunder (the “Exchange Act”)) of at least 10% of the Company’s
Common Stock (the “Minimum Ownership Threshold”), FPA shall have the right to propose up to three potential replacements that meet the Director Criteria for the New Independent Director or the 2017 Director Nominee, as applicable, should
the original appointee vacate the position by resignation or otherwise (each, a “Substitute Nominee,” and collectively, the “Substitute Nominees”). If the vacancy relates to the New Independent Director, the Nominating Committee
shall, within a reasonable period of time following the submission of the Substitute Nominees, recommend one of the Substitute Nominees for appointment to the Board. If the vacancy relates to the 2017 Director Nominee, the Nominating Committee
shall, after sharing with FPA information pertaining to its final candidates for the vacancy and giving due and careful consideration to the Substitute Nominees, recommend a candidate for appointment to the Board to fill such vacancy (the
“Replacement Nominee”). As promptly as practicable following the recommendation of either the Substitute Nominee or the Replacement Nominee to the Board, the Board shall vote upon such the appointment to the Board, upon which appointment
all references herein to the “New Independent Director” or the “2017 Director Nominee,” as applicable, shall refer to such Substitute Nominee or Replacement Nominee, as applicable. Any Substitute Nominee or Replacement Nominee
appointed in accordance with this Section 1(d) shall hold office until the 2020 Annual Meeting. If at any time FPA does not meet the Minimum Ownership Threshold, FPA will lose the right to nominate Substitute Nominees. 

  
 2 

 (e) Committees. The New Independent Director and the 2017 Director Nominee, if elected,
shall be appointed to such committees and subcommittees as determined by the Board; provided, that the Board shall not create an Executive Committee or otherwise delegate executive authority to any committee or subcommittee of the Board. The Board
shall not implement any policy restricting the ability of any Director to attend meetings of the Board or meetings of its committees or subcommittees, except to the extent (i) required by law, or (ii) advised by legal counsel to avoid any
potential conflict of interest or that is otherwise inconsistent with the Board’s fiduciary duties. 
 (f) Declassification of
Board. 
 (i) Notwithstanding anything to the contrary in this Agreement, FPA shall have the right to request that the
Board take all necessary actions (including all necessary Board approvals and recommendations, subject to the exercise of the Board’s fiduciary duties) to allow the stockholders of the Company to vote at the 2018 annual meeting of stockholders
of the Company (the “2018 Annual Meeting”) on a binding proposal to amend the Company’s Certificate of Incorporation to eliminate the Company’s classified Board (the “Classified Board Proposal”). FPA shall make such
request no later than 30 days prior to the deadline for the submission of stockholder proposals for the 2018 Annual Meeting (the “2018 Notice Deadline”). If such proposal is requested by FPA and the Board agrees with such request in the
exercise of its fiduciary duties, the Company shall include such proposal in its definitive proxy statement for the 2018 Annual Meeting, in a form mutually agreeable to both Parties, and shall support such proposal in a manner no less rigorous than
the manner in which the Company supports the Board’s other proposals at the 2018 Annual Meeting. If such proposal carries at the 2018 Annual Meeting, the Company shall promptly cause the Certificate of Incorporation to be amended and take all
other necessary actions so that the Board is no longer classified pursuant to the terms of the Classified Board Proposal. 

(ii) If the Board determines, in the exercise of its fiduciary duties, that it will not submit the Classified Board Proposal
following a request by FPA in accordance with clause (i) above, then the Board shall promptly, but in any event no later than the date that is 15 days prior to the 2018 Notice Deadline, send FPA written notice of any such determination (a
“Notice”). Upon receipt of the Notice (or, regardless of whether such Notice is given, upon the failure of the Board to comply with the obligations set forth in clause (i) by the date that is 15 days prior to the 2018 Notice
Deadline), FPA may terminate this Agreement. 
 (iii) If the Classified Board Proposal does not carry at the 2018 Annual
Meeting, or if FPA does not submit such a request by the 2018 Notice Deadline, FPA shall have the right to request that the Board submit the Classified Board Proposal at the 2019 annual meeting of stockholders (the “2019 Annual Meeting”),
in accordance with this paragraph (f) with such changes as necessary to apply to the 2019 Annual Meeting. 

  
 3 

	Section 2.	Additional Agreements. 

 (a) FPA agrees that it will cause its Affiliates, and Associates
under its control, to comply with the terms of this Agreement and shall be responsible for any breach of this Agreement by any such Affiliate, or Associate under its control. As used in this Agreement, the terms “Affiliate” and
“Associate” shall have the respective meanings set forth in Rule 12b-2 promulgated by the Securities and Exchange Commission under the Exchange Act and shall include all persons or entities that at any time during the term of this
Agreement become Affiliates or Associates of any person or entity referred to in this Agreement. 
 (b) FPA agrees that it will appear in
person or by proxy at the 2017 Annual Meeting (and, if an FPA Candidate has been appointed as the 2017 Director Nominee, the 2018 Annual Meeting) and vote all shares of Common Stock beneficially owned by FPA at such meeting or meetings: (i) in
favor of the election of the director nominees recommended by the Board, (ii) in favor of the ratification of the appointment of Ernst & Young, LLP as the Company’s independent registered public accounting firm (or such other firm
as may be determined by the Board) for the year ending September 29, 2017 or, if applicable, the year ending September 28, 2018, and (iii) in accordance with the Board’s recommendation with respect to the Company’s
“say-on-pay” proposal, unless Institutional Shareholder Services Inc. and Glass Lewis & Co., LLC recommends otherwise with respect to such “say-on-pay” proposal. 

(c) As necessary conditions precedent to appointment to the Board, and in a form acceptable to the Company, the New Independent Director (and
any Substitute Nominee or Replacement Nominee, as applicable) will promptly submit to the Company (i) a fully completed copy of the Company’s standard director & officer questionnaire and other reasonable and customary director
qualification and onboarding documentation required by the Company in connection with the appointment or election of new Board members, (ii) a written acknowledgement that the New Independent Director agrees to be bound by all lawful policies,
codes and guidelines applicable to all directors of the Company, including those regarding confidentiality, as such may be amended from time to time, and (iii) an irrevocable resignation letter pursuant to which the New Independent Director
will immediately resign from the Board and all applicable committees thereof if, at any time during the Standstill Period, FPA fails to satisfy the Minimum Ownership Threshold. 

 

	Section 3.	Standstill Provisions. 

 (a) FPA agrees that from the period from the date of execution
of this Agreement until the earlier of (x) the date that is fifteen (15) business days prior to the deadline for the submission of stockholder nominations for the 2020 annual meeting of stockholders of

  
 4 

 
the Company (the “2020 Annual Meeting”) pursuant to the Bylaws and (y) the date that is 100 days prior to the first anniversary of the 2019 Annual Meeting (the “Standstill
Period”), neither it nor any of its Affiliates, or Associates under its control, will, and it will cause each of its Affiliates, and Associates under its control, not to, directly or indirectly, in any manner, alone or in concert with others:

 (i) purchase or cause to be purchased or otherwise acquire or agree to acquire beneficial ownership of any Common Stock or
other securities issued by the Company, or any securities convertible into or exchangeable for Common Stock, such that FPA, together with its Affiliates and Associates (as defined in Section 2(a)) would, in the aggregate, beneficially own a
number of shares in excess of 15% of the then outstanding shares of Common Stock prior to the earlier of (1) the conclusion of the 2018 Annual Meeting and (2) February 28, 2018, and 20% of the then outstanding shares of Common Stock
thereafter; 
 (ii) engage in any solicitation of proxies or consents or become a “participant” in a
“solicitation” (as such terms are defined in Regulation 14A under the Exchange Act) of proxies or consents (including, without limitation, any solicitation of consents that seeks to call a special meeting of stockholders), in each case,
with respect to securities of the Company; 
 (iii) form, join or in any way participate in a partnership, syndicate or other
group, including, without limitation, any “group” (within the meaning of Section 13(d)(3) of the Exchange Act) with respect to the Common Stock (other than a “group” that includes all or some of the persons identified on
Exhibit A, but does not include any other entities or persons not identified on Exhibit A as of the date hereof); provided, however, that nothing herein shall limit the ability of an Affiliate of FPA to join the “group” following the
execution of this Agreement, so long as any such Affiliate agrees to be bound by the terms and conditions of this Agreement; 

(iv) deposit any Common Stock in any voting trust or subject any Common Stock to any arrangement or agreement with respect to
the voting of any Common Stock, other than any such voting trust, arrangement or agreement solely among the members of FPA and otherwise in accordance with this Agreement;

(x) make any public statement other than in support of the recommendations of the Board regarding how FPA intends to vote or

FPA determines in its sole discretion. 
 (b) In the event FPA’s beneficial ownership of shares of Common Stock or other securities of
the Company, or any securities convertible into or exchangeable for Common Stock, exceeds 15% of the outstanding shares of Common Stock, then FPA will not, and FPA will cause each of its Affiliates, and Associates under its control, not to, directly
or indirectly, in any manner, alone or in concert with others, in one transaction or any series of transactions, sell, dispose of, transfer, grant any option or rights with respect to, or otherwise transfer voting or investment power or economic
interest with respect to, any Common Stock or any such other securities in a privately negotiated sale, block trade or otherwise to any person or “group” (within the meaning of Section 13(d)(3) of the Exchange Act) (other than a
“group” consisting solely of some or all of the persons identified on Exhibit A and their Affiliates and Associates, whether now or hereinafter existing) if, as a result of such transaction or transactions, such person or group (to
FPA’s actual knowledge, and, with respect to privately negotiated sales or block trades directly with the counterparty, after due inquiry) would beneficially own 5% or more of the Company’s Common Stock as of the close of business on the
third day following such purchase (as determined based on the publicly available filings relating to the Company with the SEC); provided, however, that the foregoing shall not apply to (i) unsolicited sales by FPA or its
Affiliates or Associates through a broker or financial intermediary on a stock exchange that are not to a specifically identified ultimate purchaser or through so called “dark pools” that are not arranged by FPA or any of its Affiliates or
Associates or with FPA’s or its Affiliates’ or Associates’ knowledge or the knowledge of any such broker or financial intermediary of the ultimate purchaser or (ii) participation by FPA or any of its Affiliates or Associates in
any tender offer approved by the Board for the Company’s Common Stock or the exchange of its shares for the merger in a merger of the Company.

specified event) for such securities or any obligations measured by the price or value of any securities of the Company or any of its Affiliates under its control, including any swaps or other derivative arrangements designed to produce economic
benefits and risks that correspond to the ownership of Common Stock, whether or not any of the foregoing would give rise to beneficial ownership (as determined under Rule 13d-3 promulgated under the Exchange Act), and whether or not to be settled by
delivery of Common Stock, payment of cash or by other consideration, and without regard to any short position under any such contract or arrangement) and (g) FPA will not, directly or indirectly, compensate or agree to compensate the New

	Section 6.	Press Release. 

 Promptly following the execution of this Agreement, the Company and FPA
shall jointly issue a mutually agreeable press release (the “Mutual Press Release”) announcing certain 

  
 8 

 
terms of this Agreement, in the form attached hereto as Exhibit B. Prior to the issuance of the Mutual Press Release and subject to the terms of this Agreement, neither the Company (including the
Board and any committee or subcommittee thereof) nor FPA shall issue any press release or public announcement regarding this Agreement or the matters contemplated hereby without the prior written consent of the other Party. 

 

	Section 7.	Expenses. 

 Each Party shall be responsible for its own fees and expenses in connection
with the negotiation and execution of this Agreement and the transactions contemplated hereby (including actions in respect of any stockholder meeting prior to the termination or expiration of this Agreement); provided, however, that the Company
shall reimburse FPA for its reasonable, documented out-of-pocket fees and expenses (including legal expenses) incurred in connection with the matters related to the negotiation and execution of this Agreement in an amount not to exceed $125,000.

  

	Section 8.	Specific Performance. 

 Each of the members of FPA, on the one hand, and the Company, on
the other hand, acknowledges and agrees that irreparable injury to the other Party hereto would occur in the event any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and that
such injury might not be adequately compensable by the remedies available at law (including the payment of money damages). It is accordingly agreed that FPA (or any of the entities and natural persons listed in the signature pages hereto), on the
one hand, and the Company, on the other hand (the “Moving Party”), shall each be entitled to specific enforcement of, and injunctive relief to prevent any violation of the terms hereof, and the other Party hereto will not take action,
directly or indirectly, in opposition to the Moving Party seeking such relief on the grounds that any other remedy or relief is available at law or in equity. This Section 8 is not the exclusive remedy for any violation of this Agreement. 

 

	Section 9.	Severability. 

 If any term, provision, covenant or restriction of this Agreement is held
by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or
invalidated. It is hereby stipulated and declared to be the intention of the Parties that the Parties would have executed the remaining terms, provisions, covenants and restrictions without including any of such which may be hereafter declared
invalid, void or unenforceable. In addition, the Parties agree to use their best efforts to agree upon and substitute a valid and enforceable term, provision, covenant or restriction for any of such that is held invalid, void or enforceable by a
court of competent jurisdiction.

	Section 11.	Applicable Law. 

 This Agreement shall be governed by and construed and enforced in
accordance with the laws of the State of Delaware without reference to the conflict of laws principles thereof. Each of the Parties hereto irrevocably agrees that any legal action or proceeding with respect to this Agreement and the rights and
obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement and the rights and obligations arising 

  
 10 

 
hereunder brought by the other Party hereto or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom
within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware). Each of the Parties hereto hereby irrevocably submits with regard to any
such action or proceeding for itself and in respect of its property, generally and unconditionally, to the personal jurisdiction of the aforesaid courts and agrees that it will not bring any action relating to this Agreement in any court other than
the aforesaid courts. Each of the Parties hereto hereby irrevocably waives, and agrees not to assert in any action or proceeding with respect to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the
above-named courts for any reason, (ii) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to
judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by applicable legal requirements, any claim that (A) the suit, action or proceeding in such court is
brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper or (C) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. 

 

	Section 12.	Counterparts. 

 This Agreement may be executed in two or more counterparts, each of which
shall be considered one and the same agreement and shall become effective when counterparts have been signed by each of the Parties and delivered to the other Party (including by means of electronic delivery or facsimile). 

 

	Section 13.	Entire Agreement; Amendment and Waiver; Successors and Assigns; Third Party Beneficiaries. 

This Agreement contains the entire understanding of the Parties hereto with respect to this subject matter. There are no restrictions,
agreements, promises, representations, warranties, covenants or undertakings between the Parties other than those expressly set forth herein. No modifications, amendments or waivers of this Agreement can be made except in writing signed by an
authorized representative of each the Company and FPA. No failure on the part of any Party to exercise, and no delay in exercising, any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of
such right, power or remedy by such Party preclude any other or further exercise thereof or the exercise of any other right, power or remedy. All remedies hereunder are cumulative and are not exclusive of any other remedies provided by law. The
terms and conditions of this Agreement shall be binding upon, inure to the benefit of, and be enforceable by the Parties hereto and their respective successors, heirs, executors, legal representatives, and permitted assigns. No Party shall assign
this Agreement or any rights or obligations hereunder without, with respect to any member of FPA, the prior written consent of the Company, and with respect to the Company, the prior written consent of FPA. This Agreement is solely for the benefit
of the Parties hereto and is not enforceable by any other persons.
