within ten (10) days after the Date of Termination; provided, however, that no amount shall be paid until expiration of the 7-day statutory revocation period with respect to the release referred to in this Section 5.02 above. The amount
described in clause (iii) shall be paid in accordance with the terms of the applicable bonus plan subject to the attainment of the performance goals applicable to such bonus award and will be paid in such form and at such time as bonuses for
that year are paid to other executives of the Company as determined by the Compensation Committee or Board, as applicable. The 

 
amount described in clause (vi) shall be paid no later than the end of the calendar year following the year in which such expense is incurred by the Executive. The terms of all Company
restricted stock units, stock options and other equity based awards will be as set forth in the applicable award agreements and medical benefits shall be as provided in Section 5.05 below. The Executive’s entitlements under any other
benefit plan or program shall be as determined thereunder, except that severance benefits shall not be payable under any other plan or program. Notwithstanding the foregoing, if a termination of employment results in severance benefits being paid
under any change in control agreement (or any successor thereto), no amounts or benefits will be paid to the Executive under this Section 5.02 or 5.05. The Executive further agrees that in the event that the Employment Period is terminated
prior to the end of the Employment Period by the Executive under clause (c) under the definition of Good Reason, the Company may cease making payments under (ii) and (iii) above (and Executive will reimburse the Company for any

payment period during which payments under (ii) will be made. 
 SECTION 5.03. Termination Due to Death or Permanent
Disability. If the Employment Period shall be terminated prior to the end of the Employment Period due to the Executive’s death or Permanent Disability, the Executive (or his heirs, estate or legal representative) shall be entitled solely
to (i) Base Salary through the Date of Termination and any annual bonus awarded in accordance with the Company‘s bonus program but not yet paid; (ii) a pro-rata portion of the Executive’s bonus for the year of termination,
calculated by reference to the number of days during the bonus year during which he was employed by the Company; (iii) payment for all accrued, but unused, vacation time through the Date of Termination; and (iv) promptly following any such

in a single lump sum within ten (10) days after the Date of Termination. The amount described in clause (iii) shall be paid in accordance with the terms of the applicable bonus plan subject to the attainment of the performance goals
applicable to such bonus award and will be paid in such form and at such time as bonuses for that year are paid to other executives of the Company as determined by the Compensation Committee or Board, as applicable. The terms of all Company
restricted stock units, stock options and other equity based awards will be as set forth in the applicable award agreements, and the Executive’s entitlements under any other benefit plan or program shall be as determined thereunder. 

SECTION 5.04. Termination for Cause or Other Than Good Reason. If the Employment Period shall be terminated prior to the end of
the Employment Period (a) by the Company for Cause, or (b) by the Executive other than for Good Reason and not due to the Executive’s death or Permanent Disability, the Executive shall be entitled, within ten (10) days
following the Date of Termination, to receive solely (i) the Base Salary through the Date of Termination; (ii) payment for all accrued, but unused, vacation time through the Date of Termination; and (iii) reimbursement of all
Reimbursable Expenses incurred by the Executive prior to such termination. The Executive’s rights under any benefit plan or program shall be as set forth thereunder. 

SECTION 5.05. Medical Benefits. If the Employment Period is terminated as a result of a termination of employment as specified in
Section 5.02, the Executive and his dependents shall continue to receive his medical insurance benefits from the Company available through COBRA. If the Executive elects COBRA continuation coverage, the Executive shall continue to
participate in all medical insurance plans he was participating on the Date of Termination, and the Company shall pay the applicable premium. To the extent that Executive had dependent coverage immediately prior to termination of
employment, such continuation of benefits for Executive shall also cover Executive’s dependents for so long as Executive is receiving benefits under this paragraph and such dependents remain eligible. The COBRA Continuation Period for medical
insurance under this paragraph shall be deemed to run concurrent with the continuation period federally mandated by COBRA (generally 18 months), or any other legally mandated and applicable federal, state, or local coverage period for benefits
provided to terminated employees under the medical plan. For purposes of this Agreement, (a) “COBRA” means the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, and (b) “COBRA
Continuation Period” shall mean the continuation period for medical insurance to be provided under the terms of this Agreement which shall commence on the first day of the calendar month following the month in which the date of
termination falls and generally shall continue for an 18-month period or until such time as the executive is employed, whichever is earlier. 

SECTION 5.06. Notice of Termination. Any termination by the Company for Permanent Disability or Cause or without Cause
or by the Executive with or without Good Reason shall be communicated by written Notice of 

 
Termination to the other party hereto. For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of employment under the provision indicated. 

SECTION 5.07. Date of Termination. “Date of Termination” shall mean (a) if the Employment
Period is terminated as a result of a Permanent Disability, the next business day after a Notice of Termination is given following the Permanent Disability; (b) if the Employment Period is terminated as a result of death, the date of death; and
(c) if the Employment Period is terminated for any other reason, the later of the date the Notice of Termination is given or the end of any applicable correction period except as otherwise specifically provided herein. 

SECTION 5.08. No Duty to Mitigate. The Executive shall have no duty to seek new employment or other duty to mitigate following a
termination of employment as described in Section 5.02 above, and no compensation or benefits described in Section 5.02 shall be subject to reduction or offset on account of any subsequent compensation, other than as provided in
Section 5.05. SECTION 5.09. Release. Notwithstanding any other provision hereof, the Executive shall not be required by the Release to release claims that the Executive may have against the Company for reimbursement of
ordinary and necessary business expenses incurred by him during the course of his employment, claims that arise after the effective date of the Release, any rights the Executive may have to enforce Sections 5.02 of this Agreement, and claims for
which the Executive is entitled to be indemnified under the Company‘s charter, by-laws or under applicable law or pursuant to the Company’s directors’ and officer’s liability insurance policies. 

ARTICLE 6 
 CONFIDENTIAL
INFORMATION 
 SECTION 6.01. Confidential Information and Trade Secrets. The Executive and the Company agree that
certain materials, including, but not limited to, information, data and other materials relating to customers, development programs, costs, marketing, trading, investment, sales activities, promotion credit and financial data, manufacturing
processes, financial methods, plans or the business and affairs of the Company and its Affiliates, constitute proprietary confidential information and trade secrets. Accordingly, the Executive will not at any time during or after the
Executive’s employment with the Company disclose or use for the Executive’s own benefit or purposes or the benefit or purposes of any Person, other than the Company and any of its Affiliates, any proprietary confidential
information or trade secrets. The foregoing obligations imposed by this Section 6.01 will not apply (i) in the course of the business of and for the benefit of the Company, (ii) if such information has become, through no fault of
the Executive, generally known to the public, or (iii) if the Executive is required by law to make disclosure (after giving the Company notice and an opportunity to contest such requirement). The Executive agrees that upon termination
of employment with the Company for any reason, the Executive will immediately return to the Company all memoranda, books, paper, plans, information, letters and other data, and all copies thereof or therefrom, which in any way
relate to the business of the Company and its Affiliates. The Executive further agrees that the Executive will not retain or use for the Executive’s account at any time any trade names, trademark or other proprietary business
designation used or owned in connection with the business of the Company or any of its Affiliates. 
 ARTICLE 7 

NONCOMPETITION 
 SECTION
7.01. Noncompetition. (a) The Executive acknowledges and recognizes the highly competitive nature of the business of the Company and its Affiliates and accordingly agrees that during the term of the Executive’s
employment and for a period of one (1) year after the termination thereof: 
 (i) the Executive will not directly or indirectly engage
in any business which is in competition with any line of business conducted by the Company or any of its Affiliates, including, but not limited to, where such engagement is as an officer, director, proprietor, employee, partner, investor
(other than as a holder of less than 1% of the outstanding capital stock of a publicly traded corporation), consultant, advisor, agent or sales representative, in any Restricted Territory; 

 (ii) the Executive will not perform or solicit the performance of services for any customer or
client of the Company or any of its Affiliates; 
 (iii) the Executive will not directly or indirectly induce any employee
of the Company or any of its Affiliates to (1) engage in any activity or conduct which is prohibited pursuant to this Section 7.01, or (2) terminate such employee’s employment with the Company or any of its
Affiliates. Moreover, the Executive will not directly or indirectly employ or offer employment (in connection with any business which is in competition with any line of business conducted by the Company or any of its Affiliates) to any
person who was employed by the Company or any of its Affiliates unless such person shall have ceased to be employed by the Company or any of its Affiliates for a period of at least twelve (12) months; and 

(iv) the Executive will not directly or indirectly assist others in engaging in any of the activities which are prohibited under clauses
(i)-(iii) of this Section 7.01(a) above. 
 Notwithstanding the foregoing, the Executive may serve as an advisor to any person or entity that is
not directly engaged in a business which is in competition with any line of business conducted by the Company or any of its Affiliates after the Executive receives the Company’s written permission, which shall not be unreasonably
withheld. 
 (b) The covenant contained in Section 7.01(a)(i) above is intended to be construed as a series of separate covenants, one
for each county, town, city and state or other political subdivision of a Restricted Territory. Except for geographic coverage, each such separate covenant shall be deemed identical in terms to the covenant contained in the preceding subsections.
If, in any judicial proceeding, the court shall refuse to enforce any of the separate covenants (or any part thereof) deemed included in such subsections, then such unenforceable covenant (or such part) shall be deemed to be eliminated from this
Agreement for the purpose of those proceedings to the extent necessary to permit the remaining separate covenants (or portions thereof) to be enforced. 

(c) It is expressly understood and agreed that although the Executive and the Company consider the restrictions contained in this
Section 7.01 to be reasonable, if a final judicial determination is made by a court of competent jurisdiction that the time or territory or any other restriction contained in this Agreement is an unenforceable restriction against the Executive,
the provisions of this Agreement shall not be rendered void but shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable. Alternatively, if
any court of competent jurisdiction finds that any restriction contained in this Agreement is unenforceable, and such restriction cannot be amended so as to make it enforceable, such finding shall not affect the enforceability of any of the other
restrictions contained herein. 
 ARTICLE 8 

EQUITABLE RELIEF 
 SECTION
8.01. Equitable Relief. The Executive acknowledges that (a) the covenants contained in Sections 6.01 and 7.01 hereof are reasonable, (b) the Executive’s services are unique, and (c) a breach or threatened breach by
him of any of his covenants and agreements with the Company contained in Sections 6.01 or 7.01 hereof could cause irreparable harm to the Company for which it would have no adequate remedy at law. Accordingly, and in addition to
any remedies which the Company may have at law, in the event of an actual or threatened breach by the Executive of his covenants and agreements contained in Sections 6.01 or 7.01 hereof, the Company shall be entitled as a matter of
right to an injunction, without a requirement to post bond, out of any court of competent jurisdiction, restraining any violation or further violation of such promises by the Executive or the Executive’s employees, partners or agents. 

 ARTICLE 9 

INDEMNIFICATION 
 SECTION 9.01.
(a) Indemnification. The Company agrees that if the Executive is made a party, or is threatened to be made a party, to any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the
fact that he is or was a director, officer or employee of the Company or is or was serving at the request of the Company as a director, officer, member, employee or agent of another corporation, partnership, joint venture, trust
or other enterprise, including service with respect to employee benefit plans, the Executive shall be indemnified and held harmless by the Company to the fullest extent permitted or authorized by applicable law and the
Company‘s certificate of incorporation or bylaws, against all cost, expense, liability and loss (including, without limitation, attorney’s fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be
paid in settlement) reasonably incurred or suffered by the Executive in connection therewith, and such indemnification shall continue as to the Executive even if he has ceased to be a director, member, employee or agent of the Company or
other entity and shall inure to the benefit of the Executive’s heirs, executors and administrators. 
 (b) D&O
Insurance. During the Employment Period, the Company shall keep in place a directors’ and officers’ liability insurance policy (or policies) providing comprehensive coverage to the Executive to the same extent that the
Company provides such coverage for any other officer or director of the Company and, after the expiration of the Employment Period, the Executive shall be entitled to such coverage to the same extent that the
Company provides such coverage for any other current or former officer or director of the Company. 
 ARTICLE 10

Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision will be ineffective only to the extent
of such prohibition or invalidity, without invalidating the remainder of this Agreement.

(a) If any benefit provided under this Agreement is subject to the provisions of Section 409A of the Code and the regulations issued
thereunder, the provisions of the Agreement shall be administered, interpreted and construed in a manner necessary to comply with Section 409A and the regulations issued thereunder (or disregarded to the extent such provision cannot be so
administered, interpreted, or construed.) 
 (b) For purposes of the Agreement, the Executive shall be considered to have experienced a
termination of employment only if the Executive has terminated employment with the Company and all of its controlled group members within the meaning of Section 409A of the Code. For purposes hereof, the determination of controlled
group members shall be made pursuant to the provisions of Section 414(b) and 414(c) of the Code; provided that the language “at least 50 percent” shall be used instead of “at least 80
percent” in each place it appears in Section 1563(a)(1),(2) and (3) of the Code and Treas. Reg. § 1.414(c)-2. Whether the Executive has terminated employment will be determined based on all of the facts and circumstances
and in accordance with the guidance issued under Section 409A of the Code. 
 (c) For purposes of Section 409A, each severance
benefit payment shall be treated as a separate payment. Each payment under this Agreement is intended to be excepted from Section 409A to the maximum extent provided under Section 409A as follows: (i) the Employee’s termination
date and within the applicable 2 1/2 month period specified in Treas. Reg. § 1.409A-1(b)(4) is intended to be excepted under the short-term deferral exception as specified in Treas.
Reg. § 1.409A-1(b)(4); (ii) post-termination medical benefits are intended to be excepted under the medical benefits exceptions as specified in Treas. Reg. § 1.409A-1(b)(9)(v)(B); and (iii) to the extent payments are made as
a result of an involuntary separation, each payment that is not otherwise excepted under the short-term deferral exception or medical benefits exception is intended to be excepted under the involuntary pay exception as specified in Treas. Reg.
§ 1.409A-1(b)(9)(iii). The Executive shall have no right to designate the date of any payment under this Agreement. 
 (d) With respect
to payments subject to Section 409A of the Code (and not excepted therefrom), if any, it is intended that each payment is paid on a permissible distribution event and at a specified time consistent with Section 409A of the Code. The
Company reserves the right to accelerate and/or defer any payment to the extent permitted and consistent with Section 409A. Notwithstanding any provision of this Agreement to the contrary, to the extent that a payment hereunder is subject
to Section 409A of the Code (and not excepted therefrom) and payable on account or a termination of employment, such payment shall be delayed for a period of six months after the date of termination (or, if earlier, the death of the Executive )
if the Executive is a “specified employee” (as defined in Section 409A of the Code and determined in accordance with the procedures established by the Company). Any payment that would otherwise have been due or owing
during such 6-month period will be paid immediately following the end of the 6-month period in the month following the month containing the 6-month anniversary of the date of termination.

 Annex A 

SEPARATION OF EMPLOYMENT AND GENERAL RELEASE AGREEMENT 

THIS SEPARATION OF EMPLOYMENT AND GENERAL RELEASE AGREEMENT (this “Agreement”) is made as of
this              day of             ,             ,
by and between The ExOne Company, a Delaware corporation (the “Company”), and James L. McCarley (the “Executive”). 

WHEREAS, the Executive formerly was employed by the Company as Chief Executive Officer; 

WHEREAS, the Executive and Company entered into an Employment Agreement,
dated                     , 2016, (the “Severance Agreement”) which provides for certain payments and benefits in the event that the
Executive’s employment is terminated on account of a reason set forth in the Severance Agreement; and 
 WHEREAS, the Executive’s
employment with the Company was terminated for reasons that qualify the Executive to receive certain payments and benefits, as set forth in Article 5 of the Severance Agreement, subject to, among other things, the Executive’s execution of this
Release as defined therein. 
 NOW, THEREFORE, for and in consideration of the Company’s commitments in Article 5 of the Severance
Agreement, and intending to be legally bound, the Executive and the Company hereby agree as follows: 
 1. (a) The Executive does
hereby REMISE, RELEASE AND FOREVER DISCHARGE the Company, its affiliates, subsidiaries and parents, and its and their respective officers, directors, employees, and agents, and its and their respective successors and assigns, heirs, executors, and
administrators, as well as the current and former fiduciaries of any pension, welfare, or other benefit plans applicable to the employees or former employees of the Company, and the current and former welfare and other benefit plans sponsored by the
Company (collectively, “Releasees”) from all causes of action, suits, debts, claims and demands whatsoever in law or in equity, which the Executive ever had, now has, or hereafter may have, whether known or unknown, or which the
Executive’s heirs, executors, or administrators may have, by reason of any matter, cause or thing whatsoever, from the beginning of time to the date the Executive signs this Agreement, and particularly, but without limitation of the foregoing
general terms, any claims arising from or relating in any way to the Executive’s employment relationship with the Company, the terms and conditions of that employment relationship, and the termination of that employment relationship, including,
but not limited to, any claims arising under the Age Discrimination in Employment Act, the Older Workers Benefit Protection Act, Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act, the Worker Readjustment and Retraining
Notification Act, the Consolidated Omnibus Budget Reconciliation Act, the Employee Retirement Income Security Act of 1974, the Pennsylvania Human Relations Act, and any other claims under any federal, state or local common law, statutory, or
regulatory provision, now or hereafter recognized, and any claims for attorneys’ fees and costs. This Agreement is effective without regard to the legal nature of the claims raised and without regard to whether any such claims are based upon
tort, equity, implied or express contract or discrimination of any sort. 
 (b) Although Paragraph 1(a) is intended to be a general release,
it is understood and agreed that Paragraph 1(a) excludes claims related to the Executive’s right to receive the payments and benefits described in Article 5 of the Severance Agreement, as well as claims under any statute or common law that the
Executive is legally barred from releasing, such as the Executive’s entitlement to vested pension benefits. Notwithstanding any other provision hereof, the Executive shall not release claims that the Executive may have against the
Company for reimbursement of ordinary and necessary business expenses incurred by him during the course of his employment, claims that arise after the effective date of the Release, any rights the Executive may have to enforce Sections 5.02 of
the Severance Agreement, and claims for which the Executive is entitled to be indemnified under the Company‘s charter, by-laws or under applicable law or pursuant to the Company’s directors’ and officer’s liability
insurance policies. 
 (c) Nothing herein is intended to or shall preclude the Executive from filing a charge with any appropriate federal,
state or local government agency and/or cooperating with said agency in its investigation. The Executive, however, explicitly waives any right to file a personal lawsuit or receive monetary damages that the agency may recover against the Releasees,
without regard as to who brought any said complaint or charge. Employee further agrees that to the extent any relief, including monetary relief, is awarded in any such proceeding, all amounts paid as consideration under Article 5 of the Severance
Agreement shall be a setoff and credit against any such award to the fullest extent permitted by law. 

 (d) The Executive represents and agrees by signing below that the Executive has not been denied
any leave or benefit requested, has received the appropriate pay for all hours worked for the Company, and has no known workplace injuries or occupational diseases. 

(e) To the fullest extent permitted by law, the Executive represents and affirms that (i) [other
than             ,] the Executive has not filed or caused to be filed on the Executive’s behalf any claim for relief against any Releasee and, to the best of the
Executive’s knowledge and belief, no outstanding claims for relief have been filed or asserted against the Company or any Releasee on the Executive’s behalf; and (ii) [other
than             ,] the Executive has not reported any improper, unethical or illegal conduct or activities to any supervisor, manager, department head, human resources
representative, agent or other representative of the Company, to any member of the Company’s legal or compliance departments, or to the ethics hotline, and has no knowledge of any such improper, unethical or illegal conduct or activities. The
Executive agrees to promptly dismiss with prejudice all claims for relief filed before the date the Executive signs this Agreement. 
 2.
The Company does hereby REMISE, RELEASE AND FOREVER DISCHARGE the Executive from all claims, demands or causes of action arising out of facts or occurrences prior to the date of this Agreement, but only to the extent the Company knows or reasonably
should know of such facts or occurrence and only to the extent such claim, demand or cause of action relates to a violation of applicable law or the performance of the Executive’s duties with the Company; provided, however, that this release of
claims shall not in any case be effective with respect to any claim by the Company alleging a breach of the Executive’s obligations under this Agreement. [Note: The Company and the Executive may, but shall not be required to mutually agree on a
case-by-case basis at the time of the signing of this release to include the foregoing provision, or a substantially similar provision, to this Agreement.] 

3. The Executive further agrees and recognizes that the Executive’s employment relationship with the Company has been permanently
severed, that the Executive shall not seek employment with the Company or any affiliated entity at any time in the future, and that the Company has no obligation to employ the Executive in the future. 

4. The Executive further agrees that the Executive will not disparage or subvert the Company, or make any statement reflecting negatively on
the Releasees including, but not limited to, statements relating to the operation or management of the Company, the Executive’s employment and the termination of the Executive’s employment, irrespective of the truthfulness or falsity of
such statement. 
 5. The Executive acknowledges that if the Executive had not executed this Agreement containing a release of all claims,
the Executive would not have been entitled to the payments and benefits set forth in Article 5 of the Severance Agreement. 
 6. This
Agreement contains the entire agreement between the Company and the Executive relating to the subject matter hereof. No prior or contemporaneous oral or written agreements or representations may be offered to alter the terms of this Agreement. To
the extent Employee has entered into other agreements with the Company that are not in conflict with this Agreement, including, but not limited to the Severance Agreement, the terms of this Agreement shall not supersede, but shall be in addition to
such other agreements. 
 7. The Executive agrees not to disclose the terms of this Agreement or the Severance Agreement to anyone, except
the Executive’s spouse, attorney and, as necessary, tax/financial advisor. Likewise, the Company agrees that the terms of this Agreement will not be disclosed except as may be necessary to obtain approval or authorization to fulfill its
obligations hereunder or as required by law. It is expressly understood that any violation of the confidentiality obligation imposed hereunder constitutes a material breach of this Agreement. 

8. The Executive represents that the Executive has returned to the Company and does not presently have in the Executive’s possession or
control any records and business documents, whether on computer or hard copy, and other materials (including but not limited to computer disks and tapes, computer programs and software, office keys, correspondence, files, customer lists, technical
information, customer information, pricing information, business strategies and plans, sales records and all copies thereof) (collectively, the “Corporate Records”) provided by the Company and/or its predecessors, subsidiaries or
affiliates or obtained as a result of the Executive’s prior employment with the Company and/or its predecessors, subsidiaries or affiliates, or created by the Executive while employed by or rendering services to the Company and/or its
predecessors, subsidiaries or affiliates. In addition, the Executive has or will promptly return in good condition any other Company owned equipment or property, 

 
including, but not limited to, automobiles, personal data assistants, facsimile machines, copy machines, pagers, credit cards, cellular telephone equipment, business cards, laptops and computers.
At the Executive’s request, the Company will make reasonable arrangements to transfer cellular phone numbers and personal fax numbers to the Executive. 

9. Nothing in this Agreement shall prohibit or restrict the Executive from: (i) making any disclosure of information required by law;
(ii) providing information to, or testifying or otherwise assisting in any investigation or proceeding brought by, any federal regulatory or law enforcement agency or legislative body, any self-regulatory organization, or the Company’s
designated legal, compliance or human resources officers; or (iii) filing, testifying, participating in or otherwise assisting in a proceeding relating to an alleged violation of any federal, state or municipal law relating to fraud, or any
rule or regulation of the Securities and Exchange Commission or any self-regulatory organization. 
 10. The parties agree and acknowledge
that the agreement by the Company described herein, and the release of any asserted or unasserted claims against the Releasees, are not and shall not be construed to be an admission of any violation of any federal, state or local statute or
regulation, or of any duty owed by any of the Releasees to the Executive. 
 11. The Executive agrees and recognizes that should the
Executive breach any of the obligations or covenants set forth in Articles 6 and 7 of the Severance Agreement, the Company will have no further obligation to provide the Executive with the consideration set forth in Article 5 of the Severance
Agreement, and will have the right to seek repayment of all consideration paid up to the time of any such breach. Notwithstanding the foregoing, the Executive acknowledges that if the Executive breaches Articles 6 and 7 of the Severance Agreement,
and if the Company terminates or recovers any of the payments or benefits provided under Article 5 of the Severance Agreement (as provided for in Articles 6 and 7 of the Severance Agreement), the release provided by Section 1 of this Agreement
shall remain valid and enforceable. 
 12. The Executive further agrees that the Company shall be entitled to preliminary and permanent
injunctive relief, without the necessity of proving actual damages, as well as to an equitable accounting of all earnings, profits and other benefits arising from any violations of this Agreement, which rights shall be cumulative and in addition to
any other rights or remedies to which the Company may be entitled. 
 13. This Agreement and the obligations of the parties hereunder shall
be construed, interpreted and enforced in accordance with the laws of the Commonwealth of Pennsylvania. 
 14. The Executive certifies and
acknowledges as follows: 
 (a) That the Executive has read the terms of this Agreement, and that the Executive understands its terms and
effects, including the fact that the Executive has agreed to RELEASE AND FOREVER DISCHARGE the Releasees from any legal action arising out of the Executive’s employment relationship with the Company and the termination of that employment
relationship; and 
 (b) That the Executive has signed this Agreement voluntarily and knowingly in exchange for the consideration described
herein, which the Executive acknowledges is adequate and satisfactory to him and which the Executive acknowledges is in addition to any other benefits to which the Executive is otherwise entitled; and 

(c) That the Executive has been and is hereby advised in writing to consult with an attorney prior to signing this Agreement; and 

(d) That the Executive does not waive rights or claims that may arise after the date this Agreement is executed; and 

(e) That the Company has provided the Executive with a period of [twenty-one (21)] or [forty-five (45)] days within which
to consider this Agreement, and that the Executive has signed on the date indicated below after concluding that this Agreement is satisfactory; and 

(f) The Executive acknowledges that this Agreement may be revoked within seven (7) days after execution, and it shall not become
effective until the expiration of such seven (7) day revocation period. In the event of a timely revocation by the Executive, this Agreement will be deemed null and void and the Company will have no obligations hereunder or under Article 5 of
the Severance Agreement. 

 Intending to be legally bound hereby, the Executive and the Company executed the foregoing
Separation of Employment and General Release Agreement this              day
of             ,             .

Bellaire, Texas 77401 
 Dear Jim: 

On behalf of The ExOne Company, a Delaware corporation (the “Company”), I am pleased to extend to you an offer of employment with the
Company, subject to the terms and conditions set forth in this letter. 
  

			
	Title/Duties	  	You would serve in the positon of Chief Executive Officer of the Company, and I will assume the role of Executive Chairman of the Board of Directors. As required under the Company’s Bylaws, the duties of the Chief Executive
Officer will be determined from time to time as delegated or assigned by the Board. As Executive Chairman, I will continue in an executive leadership role, focusing on strategy and other matters as directed by the Board.
		
	Base Salary	  	Your base annual salary for 2017, and also pro-rata for the remainder of 2016, will be $375,000 on an annualized basis, less payroll deductions and all required withholdings.
		
	Retention Option Grant	  	To align your interests with the interests of our stockholders, the Company will issue you a one-time grant of 100,000 stock options of the Company’s common stock to be made contemporaneously with your employment. This
retention grant of options will vest one-third immediately on the grant date, and the remaining two-thirds will vest in equal parts on the first and second anniversary of your start date with the Company and may or may not be made pursuant to our
existing 2013 Equity Incentive Plan (the “Umbrella Plan”).
		
	 Targets for
 Future
Compensation Opportunities
	  	 Consistent with our past practice regarding annual incentives to our executive management team, the Compensation Committee (the
“Compensation Committee”) and the Board of Directors (the “Board”) intend to establish a 2017 executive compensation plan that will include awards under a 2017 Umbrella Annual Incentive Plan (the
“AIP”) and under the Company’s Umbrella Plan on the terms and conditions as determined by the Committee and in their sole discretion.
  

For 2017, it is intended that the Committee establish your targeted bonus opportunity for future awards under the AIP at 60% of your base salary with a maximum
amount not to exceed 120% of your base salary. Any payouts under the AIP will be conditioned on the Company achieving certain financial performance metrics established by the Committee and otherwise subject to the Committee’s discretion and
applicable to the executive management team. Any amounts that the Committee determines to award to you under the AIP may be paid in ExOne common stock or in cash, pursuant to such plan and also as the Committee may determine in its sole
discretion.

			
		  	As part of the continuing executive compensation plan arrangements, you will be eligible for additional grants of 100,000 options in 2017 and in 2018. The number of options granted would be subject to Committee negative
discretion at the time of grant based on performance factors. Furthermore, the Company agrees to work with you toward the mutual goal of establishing within the first six months of your employment, a new, modified or amended AIP and Long Term
Incentive Plan designed to enhance the retention of existing employees and to attract and retain future key personnel. It is intended that the options noted in this paragraph would be included in such plan.
		
	Employment Agreement	  	You will enter into an employment agreement with the Company in the form attached to this letter.
		
	 Acceptance/
 Start
Date
	  	Please sign and date this letter, and return it to me by August 18, 2016 or sooner if you wish to accept employment at the Company under the terms described above. We will provide you with a copy for your records. If you accept
our offer, we would like you to start on or about August 19, 2016.
