Dear Randy:

This will confirm your resignation from employment and all positions that you hold with Presbia PLC (the “Company”) and its subsidiaries (collectively, the “Presbia Group”), including as a member of the board of directors of the Company (the “Board”), effective as of December 10, 2017 (the “Separation Date”). This Separation and General Release Agreement (the “Agreement”) confirms the terms of the separation of your employment and service as a member of the Board, including the benefits described in paragraph 3 below that you will receive if you sign and return this Agreement to the Company no later than 21 days from today and do not revoke this Agreement during the 7-day revocation period described below in paragraph 6.

By signing, delivering and not revoking this Agreement, you will be entering into a binding agreement with the Company and will be agreeing to the terms and conditions in the numbered paragraphs below, including the general release of claims in paragraphs 4, 5, and 6. Therefore, you are advised to consult with an attorney of your choice before signing this Agreement. If you choose not to sign and return this Agreement within the required time-period or if you revoke your acceptance of this Agreement, you will not receive the benefits described in paragraph 3, but your resignation and Separation Date will remain effective.

1.Last Dav of Employment You acknowledge that you resigned from your employment with the Presbia Group, and that you resigned as a member of the Board (and any boards of directors of the Presbia Group), effective as of the Separation Date. You agree to take all actions that may be necessary or appropriate to effectuate such resignations, upon the Company’s request, including, but not limited to, providing letters of resignation as may be required under applicable law of foreign jurisdictions.

2.Final Salary/Wages: Vacation Pay. You have received your final pay check as of the Separation Date, which includes payment for all salary/wages that you earned through the Separation Date, less applicable withholdings and deductions. All unused and accrued vacation shall be paid to you upon execution of this Agreement. You will receive these payments even if you do not enter into this Agreement.

3.Consideration. If you choose to sign and return this Agreement within the required time-period, do not revoke this Agreement and abide by the other terms of this Agreement, the Company agrees as follows:

(a) You were granted an option the “option” under the Presbia PLC Incentive Plan (the ''Incentive Plan”) on January 28, 2015 to purchase up to 250,000 Ordinary Shares of the Company, which have previously vested. The Option shall remain exercisable for up to three years following the Separation Date (but not later than the expiration date of such Option). Except as modified hereby, the terms and conditions of the Option as set forth in the applicable option grant agreement, subject to the Incentive Plan, shall remain in full force and effect. No other options that may have previously been granted to you by the Company are or shall be outstanding;

(b) You were granted 8,247 restricted Ordinary Shares on August 5, 2016 and 12,738 restricted Ordinary Shares on March 14, 2017 collectively the “Restricted Shares”). Notwithstanding anything contained in the Restricted Share Grant Notices and related Restricted Share Agreements with respect to the Restricted Shares, the Restricted Shares shall be fully vested upon the effectiveness of this Agreement as set forth in paragraph 3.

You acknowledge that you are not otherwise entitled to the foregoing extension of the exercise period of the Option (which would otherwise expire if not exercised within ninety (90) days following the Separation Date) or to have the unvested Restricted Shares be vested to any extent, and that the Company would not agree to provide you with such benefits without your general release of claims and other promises in this Agreement.

4.General Release of Claims. In exchange for the consideration described in paragraph 3 above to which you are not otherwise entitled, you (for yourself and your heirs, executors, administrators, beneficiaries, personal representatives and assigns) hereby completely, forever, irrevocably and unconditionally release and discharge, to the maximum extent pennitted by law, the Company, the Company’s past, present and future parent organizations, subsidiaries, affiliated entities, managers, related companies and divisions and each of their respective past, present and future officers, directors, employees, shareholders, trustees, members, partners, attorneys and agents (in each case, individually and in their official capacities) and each of their respective employee benefit plans (and such plans' fiduciaries, agents, administrators and insurers, individually and in their official capacities), as well as any predecessors, future successors or assigns or estates of any of the foregoing (the “Released Parties”) from any and all claims, actions, charges, controversies, causes of action, suits, rights, demands, liabilities, obligations, damages, costs, expenses, attorneys' fees, damages, and obligations of any kind or character whatsoever, that you ever had, now have or may in the future claim to have by reason of any act, conduct, omission, transaction, agreement, occurrence or any other matter whatsoever occurring up to and including the date you sign this Agreement. This general release of claims includes, without limitation, any and all claims:

You expressly acknowledge that this general release of claims includes any and all claims arising up to and including the date you sign this Agreement which you have or may have against any of the Released Parties, whether such claims are known or unknown, suspected or unsuspected, asserted or unasserted, disclosed or undisclosed. By signing this Agreement, you expressly waive any right to assert that any such claim, demand, obligation or cause of action has, through ignorance or oversight, been omitted from the scope of this release and you further waive any rights under statute or common law principles that otherwise prohibits the release of unknown claims.

This general release of claims does not apply to, waive or affect: any rights or claims that may arise after the date you sign this Agreement; any claim for workers' compensation benefits (but it does apply to, waive and affect claims of discrimination and/or retaliation on the basis of workers' compensation status); claims for unemployment benefits; claims for indemnification in connection with your service as an officer and/or director; or any other claims or rights that by law cannot be waived in a private agreement between an employer and employee; or your rights to any vested benefits to which you are entitled under the terms of the applicable employee benefit plan.

5.Further Release By You Of the Released Parties. You expressly acknowledge that, in further consideration of the benefits set forth in paragraph 3, you waive all rights afforded by Section 1542 of the Civil Code of the State of California (“Section 1542”), or any other law or statute of similar effect in any jurisdiction with respect to the released Claims, with respect to the Released Parties. Section 1542 states: “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.” Notwithstanding the provisions of Section 1542 and for the purpose of implementing a full and complete release of all Claims, you expressly acknowledge and agree that this Agreement releases all Claims existing or arising prior to your execution of this Agreement which you have or suspect you may have against the Released Parties whether such claims are known or unknown and suspected or unsuspected by you and you forever waive all inquiries and investigations into any and all such claims. You understand and acknowledge that the significance and consequence of this waiver of Civil Code §1542, is that even if you should suffer additional injuries or damages arising out of the released Claims, you will not be permitted to make any claim for those injuries or damages.

6.Waiver of Claims under ADEA; Time to Consider/Revoke. You acknowledge, understand and agree that that the general release of claims in paragraphs 4 and 5 above includes, but is not limited to, a waiver and release of all claims that you may have under the Age Discrimination in Employment Act of 1967, as amended (the “ADEA”) arising up to and including the date that you sign this Agreement. As required by the Older Workers Benefit Protection Act of 1990, you are hereby advised that:

8.Covenant not to Sue. You covenant and agree that you will not report, institute or file a charge, lawsuit or action (or encourage, solicit, or voluntarily assist or participate in, the reporting, instituting, filing or prosecution of a charge, lawsuit or action by a third party) against any of the Released Parties with respect to any claim that has been released in this Agreement.
