Notwithstanding the foregoing, the Company may, in its sole discretion, permit the Executive to retain certain Company property during the consulting services period described in Section 7 of this Agreement and the Consulting Agreement.

3. Executive Representations. The Executive specifically represents, warrants, and confirms that the Executive:

(a) has not filed or otherwise pursued any charges, complaints, or claims of any nature against any of the Released Parties (as defined below) with any local, state, or federal government agency or court, except that Executive is not required to disclose to Employer any information provided to any government agency;

(b) has received all salary, wages, commissions, bonuses, and other compensation due to the Executive and has been fully and properly paid by the Company for work performed to date;

(c) has no work-related injuries or occupational diseases related to Executive’s employment with the Company; and

(d) except as governed by the Consulting Agreement, as of the Termination Date the Executive no longer holds any officer, director, employee, advisory or fiduciary position with the Company or any of its subsidiaries or affiliates, and he hereby resigns from any such positions to the extent such resignation is necessary to effectuate his removal.

4. Separation Benefits. As consideration for, and contingent on, the Executive’s timely execution of, non-revocation of, and compliance with this Agreement, including the Executive’s waiver and release of claims in Section 8 and other post-termination obligations, and the Executive’s timely execution of the Addendum to Executive Severance and Release Agreement attached hereto as Exhibit A on or within 3 days following the Termination Date, the Employer agrees to provide the benefits described in subsections (a) through (d) below, which are contemplated by the Employment Agreement and the additional payments and benefits described in subsections (e) through (g) below:

(a) Payment of any Base Salary amounts, less withholdings for wages, that have accrued but have not been paid as of the Termination Date and the unpaid Performance Bonus (as such term is defined in the Employment Agreement), if any, with respect to the calendar year preceding the calendar year in which the Termination Date occurs (such Performance Bonus, if any, to be determined in the manner that it would have been determined, and payable at the time it would have been payable).

(b) An amount equal to 150% of the Executive’s current Base Salary, less withholdings for wages, payable in eighteen (18) equal monthly installments, regardless of whether the Executive obtains other employment and is compensated therefor (with the first two (2) installments to be paid on the sixtieth (60^th) day following the Termination Date and the remaining sixteen (16) installments being paid on the sixteen (16) following monthly anniversaries of such date).

2

(c) Any unused vacation time accrued in the calendar year in which the Termination Date occurs, but only to the extent Company policy mandates the accrual of vacation time.

(d) If the Executive elects to continue his then current enrollment (including family enrollment, if applicable) in the health and/or dental insurance benefits set forth in the Employment Agreement in accordance with COBRA, then for a period of up to eighteen (18) months following the Termination Date, the Company will continue to pay a portion of the premiums such that the Executive’s contribution to such plans will remain the same as if the Executive were employed by the Company, such contributions to be paid by the Executive in the same period as all other employees of the Company (but deductions from the Executive’s monthly severance payments may be deemed acceptable for this purpose in the discretion of the Company); provided, however, that the Company may terminate such coverage if payment from the Executive is not made within ten (10) days of the date on which the Executive receives written notice from the Company that such payment is due; and provided, further, that such benefits shall be discontinued earlier to the extent that the Executive is no longer eligible for COBRA continuation coverage. In addition, this benefit is contingent upon timely election of COBRA continuation coverage and will run concurrent with the COBRA period. The Executive acknowledges and agrees that the amount of any such premiums paid by the Company will constitute taxable wages for income and employment tax purposes.

(e) In addition to the Executive continuing to receive the compensation and benefits contemplated by the Employment Agreement during the period commencing on the Execution Date and continuing through the Termination Date, the Executive will also receive a lump sum payment equal to six (6) months of Executive’s current Base Salary, less withholdings for wages, to be paid on the sixtieth (60^th) day following the Termination Date.

(f) The Executive shall be entitled to the vesting of any Restricted Stock Award (“RSA”) shares that are scheduled to vest through April 2027 pursuant to the terms of the applicable award agreements under the 2015 Incentive Plan of 3D Systems Corporation (the “Plan”), subject to Executive’s continued employment or service as a consultant under the Consulting Agreement through the applicable vesting date. All vested portions of such RSA shares shall remain subject to the terms and restrictions contained in the applicable award agreements and the Plan. All RSA shares not vested at the conclusion of the Executive’s employment or service under the Consulting Agreement shall be forfeited in accordance with the terms of the applicable award agreements and the Plan for no consideration.

(g) The Executive shall be entitled to any Performance-Based Restricted Stock Unit (“PSU”) shares within the Employer’s 2024 PSU plan that is scheduled to conclude in April 2027 pursuant to the terms of the applicable award agreements under the Plan, as long as they are determined to be earned based on the achievement of the applicable

3

performance criteria, subject to Executive’s continued employment or service as a consultant under the Consulting Agreement through the applicable vesting date. All vested portions of such PSU shares shall remain subject to the terms and restrictions contained in the applicable award agreements and the Plan. All PSU shares not vested at the conclusion of the Executive’s employment or service under the Consulting Agreement shall be forfeited in accordance with the terms of the applicable award agreements and the Plan for no consideration.

(h) The Parties mutually agree that the Executive has previously fully vested in the “Initial RSA shares” described in the Employment Agreement and no further vesting is required in connection with the Executive’s termination of employment.

5. Taxes. The Company may withhold from any amounts payable under this Agreement all federal, state, provincial, city or other taxes as the Company is required to withhold pursuant to any applicable law, regulation or ruling.

6. Cooperation. Following the Termination Date and thereafter, the Executive agrees that the Executive shall, without any additional compensation, respond to reasonable requests for information from the Company regarding matters that may arise in the Company’s business. The Executive further agrees to fully and completely cooperate with the Company, its advisors and its legal counsel with respect to any litigation that is pending against the Company and any claim or action that may be filed against the Company in the future.

For purposes of Section 409A, any installment payments provided under this Agreement shall each be treated as a separate payment. To the extent required under Section 409A, any payments to be made under this Agreement in connection with a termination of employment shall only be made if such termination constitutes a “separation from service” under Section 409A. Notwithstanding the foregoing, Employer makes no representations that the payments and benefits provided under this Agreement comply with Section 409A and in no event shall Employer be liable for all or any portion of any taxes, penalties, interest, or other expenses that may be incurred by Executive on account of non-compliance with Section 409A.

(b) If a payment obligation under this Agreement arises on account of the Executive’s “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h)) while the Executive is a “specified employee” (as defined under Section 409A of the Code and determined in good faith by the Compensation Committee), any payment of “deferred compensation” (as defined under Treasury Regulation Section 1.409A-1(b)(1), after giving effect to the exemptions in Treasury Regulation Sections 1.409A-1(b)(3) through (b)(12)) that is scheduled to be paid within six months after such separation from service shall accrue without interest and shall be paid on the first day of the seventh month beginning after the date of the Executive’s separation from service or, if earlier, within 15 days after the appointment of the personal representative or executor of the Executive’s estate following his death.
